Description

Technical Field

[0001] This utility model relates to a greening sprinkler system. Background Technology

[0002] In routine greening maintenance, automatic sprinkler systems have replaced traditional manual watering. Chinese Utility Model Patent Specification CN 205233039 U describes an automatic plant irrigation system, which includes a water source, a water supply pipe, and a sprinkler head device. The water supply pipe is equipped with a solenoid valve, which is electrically connected to a control mechanism and a power source. The control mechanism responds to a control signal to control the opening and closing of the solenoid valve, thereby achieving automatic irrigation of the green plants. However, for water sources at elevated locations, the water pressure and velocity are very high, which can easily impact components such as pipes, solenoid valves, and sprinkler heads, affecting the normal operation of the pipeline and even causing damage to these components.

Detailed Implementation

[0012] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0013] like Figures 1 to 5 The greening sprinkler system shown is used to spray water from a high water storage tank (not shown) to green plants at a low ground level 100. It includes a pipeline buried below the low ground level 100. The pipeline includes an inlet pipe 10, an outlet pipe 20 at the same height as the inlet pipe 10, and a water flow control pipeline 30 connecting the inlet pipe 10 and the outlet pipe 20. The inlet pipe 10 is connected to the high water storage tank. The outlet pipe 20 is provided with multiple branch risers 40 that are spaced apart along the extension direction of the outlet pipe 20. The lower end of each branch riser 40 is connected to the outlet pipe 20, and the upper end of each branch riser 40 extends upward toward the low ground level 100. A sprinkler head is installed at the upper end of each branch riser 40.

[0014] The water flow control pipeline 30 includes an ascending riser 301, a descending riser 302, and a horizontal pipe 303 that is higher than the inlet pipe 10;

[0015] The rising riser 301 is parallel to the falling riser 302. The lower end of the rising riser 301 is connected to the inlet pipe 10, and the lower end of the falling riser 302 is connected to the outlet pipe 20. The horizontal pipe 303 is connected between the upper end of the rising riser 301 and the upper end of the falling riser 302, and the horizontal pipe 303 is connected to both the rising riser 301 and the falling riser 302.

[0016] An air valve 50 is installed at the upper end of the horizontal pipe 303 or the rising pipe 301;

[0017] Pressure reducing valve 60 and solenoid valve 70 are installed at intervals on the horizontal pipe 303, and the solenoid valve 70 is located in front of the pressure reducing valve 60 along the direction of water flow.

[0018] This invention uses an air valve to stabilize the pressure inside the pipeline and a pressure reducing valve to reduce the water pressure and speed flowing to components such as the solenoid valve and nozzles, thus ensuring the normal operation of the sprinkler system.

[0019] An air valve is a type of valve used to prevent negative pressure from being generated inside a pipe due to pressure reduction waves during transient processes. It draws in air when the pressure inside the pipe is lower than atmospheric pressure and discharges air when the pressure rises above atmospheric pressure. In this embodiment, because water is drawn from a high altitude, the water flow is rapid during the descent, which can easily create trapped air inside the pipe. The air valve is used to discharge excess air, stabilizing the pressure inside the pipe and ensuring its normal operation.

[0020] Pressure reducing valves lower water pressure by reducing the local resistance of the water flow through the valve's internal flow channel. Since the water flows down from a high point at a relatively fast speed, installing a pressure reducing valve can reduce the water flow velocity and ensure the normal operation of the pipeline.

[0021] Solenoid valves can automatically control the switch to achieve timed water spraying and irrigation.

[0022] In this embodiment, the air valve 50, the pressure reducing valve 60, and the solenoid valve 70 can all be made using existing technologies.

[0023] The horizontal pipe 303 is also equipped with a manual switch valve 80, and the pressure reducing valve is located in front of the manual switch valve 80 along the direction of water flow.

[0024] A manual on / off valve is installed to allow for manual closure during pipeline maintenance, thus stopping water flow to the horizontal pipe, downcomer, and outlet pipe. After maintenance is complete, the manual on / off valve can be reopened.

[0025] In this embodiment, the figure shows that the air valve is installed at the upper end of the riser pipe. Specifically, a T-connector is provided at the upper end of the riser pipe. One end of the T-connector is connected to the upper end of the riser pipe, the other end is connected to the air valve, and the other end is connected to the horizontal pipe. Of course, the air valve can also be installed on the horizontal pipe, and when the air valve is installed on the horizontal pipe, the switch valve is located in front of the air valve along the direction of water flow.

[0026] In this embodiment, a conventional gate valve can be used as the manual switching valve.

[0027] The nozzle is an underground telescopic nozzle, including a nozzle body 401 and a nozzle inner core 402, wherein the nozzle inner core 402 is telescopically installed in the nozzle body 401.

[0028] The upper end of the branch riser 40 is equipped with a connector 403, and the nozzle body 401 is installed on the connector 403.

[0029] The upper end of the branch riser 40 is also equipped with a protective pipe 404 outside the nozzle body 401;

[0030] The lower end of the protective tube 404 is fixedly connected to the connector 403, and the upper end of the protective tube 404 is higher than the upper end of the nozzle body 401.

[0031] like Figure 4 As shown, when the nozzle inner core 402 extends out of the nozzle body 401, it is higher than the upper end of the protective tube 404;

[0032] like Figure 3 As shown, when the nozzle inner core 402 is retracted into the nozzle body 401, it is lower than the upper end of the protective tube 404.

[0033] This technical solution allows the upper end of the protective tube to bear the entire force of being stepped on when the nozzle core retracts into the nozzle body, thus preventing damage to the entire nozzle and protecting it.

[0034] In this embodiment, the structure of the buried telescopic sprinkler head can be based on existing technology, and the inner core of the sprinkler head can also be rotated 180 degrees or 360 degrees as in existing technology.

[0035] This invention is particularly suitable for installation in locations with water sources at high altitudes, such as hilltop parks.

[0036] A maintenance well 90 is provided at a low ground level 100, and the water flow control pipeline 30 is installed in the maintenance well 90. The wellhead of the maintenance well 90 is covered with an openable well cover 901. This technical solution facilitates the maintenance of the sprinkler system.
