By setting the bypass pipe, it is ensured that its multi-stage telescopic pipe can fall back completely.

[0004] Prior art application number CN201310006949.8 discloses an underground automatic telescopic integrated sprinkler irrigation device, which can be used in plain areas.

[0005] For this purpose, the present invention also provides a fully automatic telescopic sprinkler irrigation equipment return system suitable for plain areas. Summary of the invention

[0006] The main purpose of the present invention is to provide a fully automatic telescopic sprinkler irrigation equipment return system suitable for plain areas, which can effectively solve the problems in the background technology.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] The fully automatic telescopic sprinkler irrigation equipment return system includes a sprinkler irrigation system, which is mainly composed of a plurality of underground sprinkler irrigation equipment, and the underground sprinkler irrigation equipment includes a pipe sleeve, a primary telescopic pipe, a secondary telescopic pipe and a spray group, and includes a power system, which is mainly composed of a water pump, a controller, a main pipe and a branch pipe. The bottom of the pipe sleeve is connected to the branch pipe, and the water pump is connected to the branch pipe through the main pipe. The controller controls the water pump to supply water to the sprinkler irrigation system;

[0009] It also includes a gutter system, which is mainly composed of a gutter and an auxiliary connecting branch pipe, and the gutter is connected to the pipe sleeve through the auxiliary connecting branch pipe;

[0010] Solenoid valve a and solenoid valve b are arranged in the branch pipe and the auxiliary connecting branch pipe in sequence, and are all controlled by a controller. The controller controls the solenoid valve a, the solenoid valve b, the water pump and the gutter system, that is, it assists the sprinkler irrigation equipment in falling back, so that the sprinkler irrigation equipment can also fall back completely in plain areas.

[0011] Furthermore, the gutter includes a cement-cast trough shell with no bottom. The upper middle position of the inner surface of the trough shell is divided from top to bottom into a water storage area and a falling area by a rotating water gate. The controller controls the operation of the rotating water valve. When the controller controls the operation of the overall system, the sprinkler irrigation equipment is in the sprinkler irrigation state, and water is stored in the water storage area. After the sprinkler irrigation is completed, the controller controls the rotating water gate to open and let the water in the water storage area fall into the falling area, generating a siphon force to assist the sprinkler irrigation equipment to fall back.

[0012] Furthermore, the rotating water gate includes a leakage disc fixed to the inner surface of the tank shell and a valve disc arranged on the top of the leakage disc and rotating concentrically relative to the leakage disc. A reduction motor is fixedly connected to the middle position of the bottom of the leakage disc. The output shaft of the reduction motor is fixedly connected to the valve disc through a coupling and a transmission shaft. The controller controls the operation of the reduction motor. The controller controls the rotation of the reduction motor to drive the valve disc to rotate, change the relative position of the leakage disc, and realize the function of opening and closing the valve.

[0013] Furthermore, a plurality of fan-shaped openings are provided at equal angles on the front side of the leakage disc, the valve disc comprises a seat sleeve, a plurality of fan-shaped valve discs are provided at equal angles on the outer surface of the seat sleeve, the fan-shaped openings correspond one to one with the fan-shaped valve discs, that is, when water is stored in the water storage area, the fan-shaped valve disc is located directly above the fan-shaped openings, and when water is not stored in the water storage area, the reduction motor rotates to drive the fan-shaped valve disc so that there is no obstruction at the fan-shaped opening position.

[0014] Furthermore, the control logic of the controller is that during sprinkler irrigation, the water pump is controlled to work, and the solenoid valve a and the solenoid valve b are opened. At this time, water enters the sprinkler irrigation equipment and the water storage area. After the water in the water storage area is filled, the controller still controls the water pump to work, and then the sprinkler irrigation equipment drills out of the ground from the ground under the action of water pressure to achieve sprinkler irrigation. After the sprinkler irrigation is completed, the solenoid valve b is closed and the solenoid valve a is opened. The water in the sprinkler irrigation equipment will flow back to the water source through the main pipe and the branch pipe and through the water pump. The process of water flow backflow drives the sprinkler irrigation equipment to fall back. Because it is in a plain area, the water level difference is not large, resulting in the sprinkler irrigation equipment not falling back completely. After 20-60s, the sprinkler irrigation equipment is in a relatively prohibited state, solenoid valve a is closed and solenoid valve b is opened, that is, the water storage area and the auxiliary connecting branch pipe form a closed space with the sprinkler irrigation equipment. The controller controls the reduction motor to rotate, which in turn drives the valve disc to rotate. After rotating a certain angle, there is no obstruction at the fan-shaped mouth position. After 10-30s, the water in the water storage area completely flows to the water drop area, generating a siphon force, and the sprinkler irrigation equipment in the prohibited state continues to fall back to the original state. The reduction motor is controlled to rotate a certain angle, that is, the fan-shaped valve disc is located directly above the fan-shaped mouth, completing a working cycle.

[0015] Working principle and beneficial effects: The solenoid valve a, solenoid valve b, water pump and gutter system are controlled by the controller, which assists the sprinkler irrigation equipment in falling back, so that the sprinkler irrigation equipment can also fall back completely in plain areas, which can effectively solve the problems existing in the background technology.

[0016] (1) When the controller controls the operation of the overall system, the sprinkler equipment is in the sprinkler irrigation state, and water is stored in the water storage area. After the sprinkler irrigation is completed, the controller controls the water gate to open and let the water in the water storage area fall into the falling area, generating a siphon force to assist the sprinkler equipment to fall back.

[0017] (2) The gutter system is connected to multiple sprinkler irrigation equipment through auxiliary connecting branches, which can assist the return of multiple sprinkler irrigation equipment. That is, one gutter system can help the return of multiple sprinkler irrigation equipment, which is economical and practical. BRIEF DESCRIPTION OF THE DRAWINGS

The controller controls the electromagnetic valve a, electromagnetic valve b, water pump and water trough system, that is, when the sprinkler irrigation equipment falls back, it assists its fall back, so that the sprinkler irrigation equipment can also fall back completely in the plain area. The control logic of the controller is that when sprinkling, the water pump is controlled to work, and the electromagnetic valve a and the electromagnetic valve b are opened. At this time, water enters the sprinkler irrigation equipment and the water storage area. After the water in the water storage area is filled, due to The controller still controls the water pump to work, and then the sprinkler irrigation equipment drills out of the ground from the ground under the action of water pressure to achieve sprinkler irrigation. After the sprinkler irrigation is completed, the solenoid valve b is closed and the solenoid valve a is opened. The water in the sprinkler irrigation equipment will flow back to the water source through the main pipe and the branch pipe and through the water pump. The sprinkler irrigation equipment is driven to fall back during the water flow back.
