Well with bicycle-type pedal hoist

FIELD: construction.

SUBSTANCE: well is made of a wellbore, a water tank, and a manually-driven winch. The water tank is equipped with a rope connected with its upper end through the drum of the manually-driven winch to the drum on the shaft of a bicycle-type pedal hoist. The supporting frame with the operator seat is mounted on the wellbore. The water tank is equipped with a counterweight equipped with a thin rope wound on the drum of the manually-driven winch in the direction opposite to the rope of the water tank. The water tank is equipped with an unbalanced mass in the form of a steel rod of small length, which is hung at the ends by two wire loops to the bow of the water tank.

EFFECT: increasing the efficiency of lifting water from the well.

FIELD: oil and gas industry.

SUBSTANCE: water supply well includes a casing pipe. Pump (4), perforated filter (1), increased pressure line and electric motor (7) are installed in the pipe. Perforated filter (1) is made in the form of a piece of pipe with perforation (2) on its surface. Additional perforated pipe (11) is installed in the water intake influence zone. Perforated pipe (11) is equipped with an ejector, the active nozzle of which is connected to the pipe. Air supply confuser (20) with return valve (21) is connected to the ejector.

EFFECT: improving the pump capacity, continuous operation of the water supply well and improving efficiency due to increase in common air access to vacuum area.

FIELD: construction.

SUBSTANCE: water-intake well comprises a perforated filter, a head and a bleed pipe. The perforated filter is arranged in the form of a pipe with perforation on its surface. The head is connected to the filter. The bleed pipe is communicated via the bellows with a collector pipe. The axes of perforated holes of the perforated filter make angles with the pipe axis from 30 to 60 degrees. Perforated holes of the perforated filter are drilled bottom-up.

EFFECT: continuous and long-term operation of water-intake well.

SUBSTANCE: simulator consists of wheels, a frame, a pedal mechanism. On the shaft of the carriage on each its side, there are two combined rods, of which one right and one left rods are rigidly fixed, the other two heteronymous rods are movably placed on the axis of the carriage and have dosed free movement relative to it and fixedly secured rods. The strain-gauges are located between the movable and fixedly mounted rods and control the power of application at all points of the circular pedalling, and the audio signal enables the cyclist to reveal independently own mistakes.

EFFECT: registration of parameters and determining the efficiency during pedalling.

SUBSTANCE: drive sprocket rims are arranged on overrunning coupling. Drive comprises pair of boomerang-like bell cranks, each having pedal arm resting upon opposite ends of carriage shaft and arm that transfers torque. Both aforesaid arms are bent in the plate perpendicular to carriage axis to form boomerang-like shape. Arm that transfers torque is rigidly coupled with similarly bent element intended for transfer of toque to carriage shaft. Overrunning coupling is rigidly coupled with aforesaid elements that transfer torque. Pedal arm of one of the levers and arm that transfers torque are furnished with weights rigidly fixed thereon. Aforesaid drive is designed for bicycles, bicycle-tandems and bicycles with trailers.

EFFECT: optimising pedaling, increased tractive characteristics.

FIELD: transport engineering; bicycles.

SUBSTANCE: invention relates to fastening of bicycle pedals on shaft of crank. Two bearing units 3, 4 are arranged on shaft 1, with hollow housing of pedal 5 fitted on bearing units. One of bearing units, namely unit 3, is mated with surface of crank 2. thread is made on inner surface of hollow housing of pedal 5 in which hollow bolt 6 is fitted to serve as stop for other bearing unit 4. Nut 7 thrusts bearing unit 4 from outer side of shaft 1. Thrust end face surface of hollow bolt 6 is arranged at distance equal to approximately 1/4 of length of housing of pedal 5 from its axis of symmetry along shaft 1 in outward direction.

EFFECT: decreased deformation of pedal shaft owing to reduction of arm creating bending moment, facilitated assembling of pedal.
