Automatic humidity controller
(57) Abstract:The automatic controller is designed to control irrigation during the irrigation of farmlands or greenhouses. The regulator has a lever, one arm associated with the humidity sensor and the other with the load. Axis of the lever is located below its center of gravity. The sensor is designed as a container filled with soil from irrigated land. Soil capacity connected with irrigated soil using filters. Capacity is the ability of vertical movement in the chamber. Weight capacity determines the position of the lever, and by increasing the moisture capacity allows you to cut off the body, decreasing to open it. This gives the opportunity to improve the quality of irrigation and to increase the reliability of the device. 1 C.p. f-crystals, 2 Il. The invention relates to agriculture, relates to irrigation devices and can be used for irrigation on the plot.A device for automatic control of irrigation using the humidity sensor and automation of irrigation for a given soil moisture with the supply and drain pipes, the Executive mechanism with a flow control valve and the Converter; the device is hydroprene has a locking device, connected kinematically with a flow control valve. This device provides a predetermined humidity, but it is difficult in manufacture and maintenance .Known automatic humidity controller with humidity sensor placed in the soil and in the form of a diaphragm chamber filled with water, connected to the bellows, suspended on a spring loaded arm. One end of the lever is equipped with a valve that closes the drain pipe of the hydraulic cylinder. The increase in soil moisture leads to an increase in its weight, the deflection of the membrane chamber and the overflow of water in the bellows. The increase in the weight of the bellows leads to overlapping of the pipe, movement of the piston of the hydraulic cylinder in the upper position and closing the valve. To set control limits soil moisture applies the adjustment screw. The specified analog has the following disadvantages: constantly flowing out of the cylinder a small stream of water leads to water logging and low areas of the soil. In addition, the movable seal between the cylinder and the piston rod and the cylinder, the stem and the valve housing body are unreliable elements .The objective of the invention is to improve the quality of irrigation of the soil, reducing prosachivaetsya reliability of the device.The task is characterized by the fact that automatic humidity controller has a humidity sensor placed in the soil and in the form of vessels, placed together with flexible filters in the camera. Capacity with filters is the possibility of vertical movement in the chamber. The position of the two shoulders of the lever is determined by the influence of the weight capacity on the lever with the load. The axis of the two shoulders of the lever is located below its center of gravity, and due to this, the lever has only two stable positions: one of his shoulders is always omitted, the other raised. At any position of the lever acts on the Cam, which, in turn, interacts with the locking body or actuator interconnected hydraulically. In the hydraulic system connected to the supply pipe with throttle. When this actuator is made in the form of a chamber of the diaphragm, and a stop valve in the form of a hose valve.Comparative analysis of the claimed invention with analogue has allowed to establish that both inventions have a humidity sensor in the soil, on the lever unit humidity, a stop valve and an actuator connected hydraulically. However, the invention differs in that the data in the cell, with it the possibility of vertical travel. The position of the two shoulders of the lever is determined by the influence of the weight capacity on the lever with the load. This lever with the load has an axis located below its center of gravity, and has due to this, only two stable positions. Moreover, the position of the lever through the rocker is the impact on the locking lever or actuator. Thus, it can be concluded according to the invention, the criterion of "novelty". The features distinguishing the claimed solution to the prototype, not identified in the radiation of the art and, therefore, provide the claimed solution according to the criterion of "significant differences".In Fig. 1 shows a regulator in the closed position; Fig. 2 - in the "open" position, the area of the drain line enters the water.Automatic humidity controller contains located in the soil moisture sensor in the form of the container 1 with soil from the area and flexible filters 2, placed in the chamber 3. Flexible filters 2 connect the soil of irrigated land with soil capacity, so when moist or dry soil capacity changes its weight, and to this end, the capacity has vozmojnostyam the position of the two shoulders of the lever 4, axis 6 which is located below its center of gravity. On one lever arm is installed setpoint humidity 7, and each shoulder has projections 8 and 9 to control rocker 10. The rocker arm 10 with the rotary axis 11 has a plate 12 and pin 13. A stop valve 14 is in the form of a hose valve, which is formed of a flexible tube 15 and the plate 12. A stop valve 14 is connected with the supply pipe 16 and the actuating mechanism 17, is made in the form of a diaphragm chamber 18 with the membrane 19 and the rigid center 20. When humidity irrigated land within the limits of the reference humidity, the controller is in the following position: vessel 1 is in the lower position in the chamber 3, and the lever 4 is tilted to the left, the load 5 is at the top. The lever 4 lug 8 presses the rocker arm 10, the right shoulder raised up and the left down. The supply pipe 16 with the choke 21 is hydraulically connected with the actuating mechanism 17 and the locking body 14, so that when the humidity of the irrigated area within a given rigid center 20 of the actuator due to the water pressure in the hydraulic system provides the effect on the finger 13 of the rocker arm 10. Thus, the flexible tube 15 parijata plate 12 of the rocker arm 10 and, therefore, shut the characteristic capacity of 1, the lever 4 is rotated on the axis 6 and takes a more extreme position: the shoulder of the lever with the load at the bottom. The guide lever 9 presses the rocker arm 10, which is rotated on an axis 11 and occupies a different position: the finger 13 of the rocker arm 10 presses on the hard center 20 and respectively on the membrane 19. In this membrane bending, a stop valve is opened. Once opened stop valve 14 and appeared the rate of flow through the orifice 21, the pressure in the diaphragm chamber 18 decreases due to the pressure loss at the orifice 21, the membrane bending deeper, the plate 12 is raised even higher, and the water flow rate increases. In the membrane 19 with a rigid center 20 is at the lower position, and the plate 12 is at the top. A stop valve is open. This process lasts from 0.5 C to 1 C.In the process of watering when the soil is saturated with water to the desired humidity at a certain moment capacity 1 drag and drop a load 5, the lever 4 rotates on the axis 6 and will take a more extreme position. When the guide lever 8 presses the rocker arm 10, which is rotated on the axis 11. This plate 12 acts on the flexible tube 15 and reduces its flow section. By reducing water flow through the throttle 21 a drop in water pressure on the choke smart is the first section of flexible pipe 15 and the reduction of water consumption. In the end, a stop valve 14 is closed. The overlap time from 0.5 seconds to 1 secondThus, solved the main task of the invention is the elimination of seepage water, which is ensured by the design of the controller and confirmed by the description, as well as increased reliability due to the absence of moving seals.This device can be implemented in the factory using conventional mechanical presses with a capacity of 10 tons and 25 tons with using stamps.
