The invention relates to devices and mechanisms for exploitation of groundwater sources and intakes, particularly for pumping of artesian water in the main line of urban water systems.

Known devices for water supply from wells containing discharge pipe immersed in the borehole multistage pump gear shaft running inside the discharge pipe, and a motor mounted on the frame above the mouth of the well [1].

The presence of known devices gear transmission, not allowing you to accurately adjust the clearance between the impellers and guide apparatus of the pump, leading to a greater volume loss, reduced feed pressure and efficiency of the pump.

Closest to the proposed technical substance and dostigaev the pipeline, multi-section pump with submersible motor and the device hydroplane installed on the delivery pipe below the static water level in the well, and is designed as a sealing element, the inner cavity of which is connected with a line of high pressure, laid along the discharge pipe to the mouth of the well [2].

A disadvantage of the known device is the unreliability of the seal, which is a consequence of the presence of the water column above the sealing element, made in the form of inflatable chambers, while the impact from the bottom to the specified element of the discharged air.

The objective of the invention is the creation of a reliable seal between the walls of the discharge pipe and casing of the well.

The problem is solved in that the device for supplying water from wells containing housed in a casing pipe, discharge pipe, multi-section pump with submersible motor and the device hydroplane installed on the delivery pipe below the static water level in the well, the device hydroplane equipped with a locking mechanism and is made in the form of upper and lower support flanges pressure the melting mounted the lower edge of the first sealing element, with the upper edge of which is pivotally connected movable axis scenes rocker mechanisms, fixed axis, wings pivotally connected with the upper support flange, links rocker mechanisms are rigidly connected with the upper end of the float, which is fixed to the rod locking mechanism placed with the possibility of reciprocating displacement in the vertical through holes of the upper support flange, the rod is made one recess balls locking mechanism, provided with compression springs and one placed in a horizontally oriented holes of the upper support flange, made from the side walls of the casing and the upper end of the lower support flange, diameter which exceeds the inner diameter of the float is provided with a second sealing element.

In Fig. 1 is a diagram of the proposed device for supplying water from the well of Fig. 2-3 explains the work of his devices hydroplane.

The device is located in the casing pipe 1 well and contains a section of the discharge pipe 2 with a flange 3, a multiple pump 4 water intake grid 5, submersible motor 6 and mounted on section 7 discharge pipe is wow sealing elements 11 and 12. In addition, the device hydroplane equipped with a valve and rocker mechanisms. The composition of the locking mechanism included housed in a vertically oriented holes of the upper support flange, the rod 13 with grooves 14 and the balls 15 are located compression springs 16 in a horizontally oriented holes specified flange. The rocker mechanism composed of the wings 17, movable and fixed axis 18 and 19 which are pivotally connected with the upper edge of the first sealing element and the upper support flange, respectively, and link 20, is rigidly connected with the upper end of the float. The first sealing element mounted on the float by means of a clamp 21 (Fig. 1-3).

The device operates as follows.

The natural water level in the well is characterized by a static level (line I in Fig. 1). After you enable the submersible motor 6 specified level is reduced by the amount So that an appropriate balance between the amount of water pumped by the pump 4 through the intake grid 5, and the amount of water influx from the aquifer. With the occurrence of the equilibrium in the well continuously during operation of the device dynamotive funnel depression radius Ro.

Distance So between dynamic and static water levels in proportion to the productivity of the well. When this static level is determined by the hydrodynamic features of groundwater and the value of the atmospheric pressure and the dynamic level should be not less than half a meter above multistage pump 4, which provides the desired cooling of the housing of the latter. I.e., with decreasing natural water level (line III in Fig. 1) as a result of, for example, the beginning of the operation of additional wells, the power intake will fall by an amount proportional to the value of dSx.

Therefore, to compensate for the effects of static level on the performance of the pump 4, the device is equipped with a device hydroplane in the composition of the upper and lower support flanges 8 and 9, the float 10, the first and second sealing elements 11 and 12, and also shut and rocker mechanisms (Fig. 1).

The lower edge of the first sealing element 11 is mounted on the outer side of the float 10 by means of the clamp 21 and the upper edge of the hinge is connected with the moving axes 18 of the wings 17, a stationary axis 19 which is pivotally connected to the upper support flange 8. In horizontally landmark is the second ball 15 of the locking mechanism from the side of the casing 1 of the well. The rods 13 locking mechanism rigidly connected to the float 10, posted with the possibility of reciprocating displacement in end-to-end and vertically oriented holes flange 8 (Fig. 2-3).

The number of sections of the discharge pipe 2, successively joined by means of flanges 3 at immersing the device in the casing 1 and the preceding sections 7, equipped with a device hydroplane, choose from the calculation that the interface in the well crossed the wall section 7 above the float 10, installed in the original condition in which the balls 15 of the locking mechanism under the action of springs 16 are accommodated in the recesses 14 of the rod 13. The distance from the upper end of the float 10 to the recesses 14 is chosen so that the condition of the float 10 17 scenes were being held in a position where there is a gap between the first sealing element 11 and the casing pipe 1, makes it possible to mount the device (Fig. 2).

After mounting the unit to a predetermined depth start the motor 6. Under the action of hydraulic shock in the moment of starting the float 10 disables locking mechanisms (with a sharp displacement of the float 10 with the rod 13 down balls strobino power pump 4.

With the lowering of the water level in the casing pipe 1, the float 10 is lowered to the second sealing element 12 mounted on the upper end of the lower support flange 9 and at the same time, acting through the links 20 in 17 scenes, translates rocker mechanisms in the operating position, in which the upper edge of the sealing element 11 is pressed against the walls of the casing 1 under the action of centrifugal force pump 4 is securely block the gap between the casing pipe 1 and the outer side wall of the float 10, and the gap between the inner side wall of the float 10 and the discharge pipe 2, resulting in the achievement of dynamic water level in the well will be accompanied by a weakening effect on the boundaries of atmospheric pressure, which causes an additional inflow of water from the aquifer in siege tube 1 wells (Fig. 3).

In the moment of switching off the electric motor 6 as a result of sharp increase of water level in the well is exerted on the float 10 hammer, which trigger locking mechanisms. When this float 10 rocker mechanisms are returned to the initial position, at which reversed the above gaps for a smooth ascent eliminate the element is provided, the consequence of which is the unreliability of seals in the prototype, the proposed device is a prerequisite for reliable operation of the devices hydroplane.

SUBSTANCE: water-intake tubular well comprises a perforated casing pipe in soil arranged with its perforated section in a water-bearing layer of rocks, and a water-lifting device in it. At the upper end the casing pipe is equipped with a cover with a collar installed on it, on the cord of which there is a water-lifting pipe suspended. The water-lifting pipe has an injection valve at the lower input and a circular body along the casing pipe diameter with a suction valve and elements of hydraulic seal along the external diameter in the form of circular grooves. To drill a water-intake tubular well, a device is used, which comprises drilling pipes and a cutting drilling bit. The drilling bit is equipped with a container with a valve made of light material, for instance, plastic, to stock damaged rock. Drilling pipes are lighter pipes, for instance, water-gas pipes. On the upper end of drilling pipes there is a transverse lever of rotation. In case of high drilling depth a device is used for lowering and raising operations, including a clamp of drilling pipes and a support for clamp placement. The support is made in the form of a well head with openings of trapezoidal shape on the upper end. The clamp is made of one movable and one fixed halves with a tightening bolt and radial levers laid into openings of the well head.

EFFECT: increased height of water raising from a water-intake tubular well.
