Description

Technical Field

[0001] The utility model relates to the technical field of vegetation irrigation equipment, in particular to a water circulation irrigation system used for urban landscape greening. Background Art

[0002] In order to improve the beauty of the city and increase the oxygen content of the city, landscape greening is usually set up in the city. In addition to being set up in concentrated areas, general landscape greening is also set up in the middle of the road as a green belt, which also has the effect of dividing the road. In order to ensure the healthy growth of green plants during use, the plants need to be watered regularly.

[0003] A Chinese invention patent application with publication number CN115316228A discloses a water circulation irrigation system for urban landscaping, which belongs to the technical field of vegetation irrigation equipment. The system includes a water intake well and a pumping pipe connected to the water intake well; one end of the pumping pipe is located below the liquid level inside the water intake well, and the other end extends to the outside of the water intake well; and a water pump is connected to the pumping pipe; a soil watering mechanism for watering the soil and a vegetation spraying mechanism for spraying water on vegetation leaves are provided at one end of the pumping pipe located outside the water intake well.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned device, water is transported through a water pipe to irrigate green plants, and impurities will accumulate inside the water pipe after long-term use. At this time, if the impurities cannot be cleaned, it is easy to cause the water flow inside the water pipe to flow back, thereby causing the water pipe to be unable to irrigate the green plants normally. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a water circulation irrigation system for urban landscaping.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a water circulation irrigation system for urban landscaping, comprising a water inlet pipe, a connecting piece is installed on the side wall of the water inlet pipe, a through hole is penetrated through the side wall of the connecting piece, a water outlet pipe is installed at the end of the connecting piece away from the water inlet pipe, the water inlet pipe, the through hole and the water outlet pipe are directly opposite, a sprinkler head is installed at the end of the water outlet pipe away from the connecting piece, and an anti-backflow device for reducing the probability of backflow is installed in the connecting piece.

[0007] By adopting the above technical solution, when the staff needs to water the green plants, the water flows from the water inlet pipe to the through hole, then moves to the water outlet pipe, and finally, the water is sprayed through the sprinkler head to water the green plants. During this process, when the sprinkler head or the water outlet pipe is blocked, the anti-backflow device is activated, thereby reducing the probability of the water in the water outlet pipe flowing into the water inlet pipe, thereby reducing the probability of backflow.

[0008] Furthermore, a rotating groove is symmetrically opened on the inner wall of the through hole, and the backflow prevention device includes two rotating rods rotatably arranged in the rotating grooves, a fixed plate fixedly arranged on the inner wall of the through hole, and a rotating plate rotatably arranged in the through hole, the side walls of the two rotating rods close to each other are fixed to the rotating plate, and the side wall of the rotating plate close to the water inlet pipe is in contact with the side wall of the fixed plate away from the water inlet pipe.

[0009] By adopting the above technical solution, when water flows from the water inlet pipe to the water outlet pipe, the rotating plate rotates under the action of the water flow, thereby causing the water to flow into the water outlet pipe. At this time, when the sprinkler head or the water outlet pipe is blocked, the water flows from the water outlet pipe to the water inlet pipe. During this process, the rotating plate rotates under the action of the water flow. During this process, when the side wall of the rotating plate abuts against the side wall of the fixed plate, the fixed plate blocks the rotating plate, thereby preventing the rotating plate from rotating. Therefore, the rotating plate blocks the water flow, thereby reducing the probability of backflow.

[0010] Furthermore, a reset groove is provided on the inner wall of the rotation groove, a torsion spring is fixedly arranged on the inner wall of the reset groove, and the other end of the torsion spring is fixedly arranged on the side wall of the rotation rod away from the rotation plate.

[0011] By adopting the above technical solution, when watering is stopped, the water flow loses power and stops flowing. At this time, the rotating plate is reset under the action of the torsion spring, thereby reducing the difficulty of the staff to reset the rotating plate, thereby reducing the difficulty of the staff's work.

[0012] Furthermore, one end of the rotating plate away from the inner wall of the through hole is provided with a rounded corner.

[0013] By adopting the above technical solution, the rounded corners reduce the probability of the rotating plate colliding with the fixed plate when rotating, thereby improving the stability of the device.

[0014] Furthermore, a filter screen is fixedly arranged on the inner wall of the water inlet pipe.

[0015] By adopting the above technical solution, the filter screen filters impurities in the water flow, thereby reducing the probability of the water outlet pipe and the sprinkler head being blocked, thereby reducing the probability of backflow.

[0016] Furthermore, a backflow prevention plug is fixedly provided on the inner wall of the through hole, the upper end of the backflow prevention plug is fixed to the inner top wall of the through hole, the lower end of the backflow prevention plug is abutted against the bottom surface of the through hole, and an installation groove is provided on the side wall of the backflow prevention plug close to the water outlet pipe.

[0017] By adopting the above technical solution, when water flows from the water inlet pipe to the water outlet pipe, the lower end of the backflow prevention plug is lifted up by the water flow, thereby allowing the water to flow into the water outlet pipe. Subsequently, when water flows from the water outlet pipe to the water inlet pipe, the water flows into the installation groove. During this process, since the lower end of the backflow prevention plug abuts against the inner wall of the through hole, the backflow plug cannot be lifted up, thereby causing the backflow plug to block the water flow, thereby reducing the probability of the water flowing into the water inlet pipe.

[0018] Furthermore, the backflow prevention plug is made of rubber material.

[0019] By adopting the above technical solution, the backflow prevention plug made of rubber material reduces the difficulty of lifting and releasing the backflow plug by water flow, thereby reducing the work difficulty of the staff.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to water the green plants, the water flows from the water inlet pipe to the through hole. Then, it moves to the water outlet pipe, and finally, the water is sprayed through the sprinkler head to water the green plants. During this process, when the sprinkler head or the water outlet pipe is blocked, the anti-backflow device is activated, thereby reducing the probability of water in the water outlet pipe flowing into the water inlet pipe, thereby reducing the probability of backflow;

[0022] 2. In the present application, when water flows from the water inlet pipe to the water outlet pipe, the rotating plate rotates under the action of the water flow, thereby causing the water to flow into the water outlet pipe. At this time, when the sprinkler head or the water outlet pipe is blocked, the water flows from the water outlet pipe to the water inlet pipe. During this process, the rotating plate rotates under the action of the water flow. During this process, when the side wall of the rotating plate abuts against the side wall of the fixed plate, the fixed plate blocks the rotating plate, thereby preventing the rotating plate from rotating. Thus, the rotating plate blocks the water flow, thereby reducing the probability of backflow.

[0023] 3. In the present application, when watering is stopped, the water flow loses power and stops flowing. At this time, the rotating plate is reset under the action of the torsion spring, thereby reducing the difficulty of the staff to reset the rotating plate, thereby reducing the difficulty of the staff's work.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] Example 1

[0031] like Figure 1-3 As shown, the embodiment of the present application discloses a water circulation irrigation system for urban landscaping, including an inlet pipe 1, a connector 11, an outlet pipe 12, a sprinkler head 13, an anti-backflow device 3, a torsion spring 4 and a filter 6. The inlet pipe 1 is a circular tubular structure with a horizontal axis. The connector 11 is mounted on the side wall of the inlet pipe 1, and its axis coincides with the axis of the inlet pipe 1. A through hole 2 is provided through the side wall of the connector 11. The outlet pipe 12 is a circular tubular structure, and its axis coincides with the axis of the inlet pipe 1. The outlet pipe 12 is mounted at one end of the connector 11 away from the inlet pipe 1, and the inlet pipe 1, the through hole 2 and the outlet pipe 12 are directly opposite. The sprinkler head 13 is mounted at one end of the outlet pipe 12 away from the connector 11, and is used to water green plants.

[0032] When the staff needs to water the green plants, the water flows from the water inlet pipe 1 to the through hole 2. Then, it moves to the water outlet pipe 12, and finally, the water is sprayed through the sprinkler head 13 to water the green plants. During this process, when the sprinkler head 13 or the water outlet pipe 12 is blocked, the anti-backflow device 3 is activated, thereby reducing the probability of the water in the water outlet pipe 12 flowing into the water inlet pipe 1, thereby reducing the probability of backflow.

[0033] The inner wall of the through hole 2 is symmetrically provided with a rotation groove 21. The backflow prevention device 3 is installed in the connecting piece 11 to reduce the probability of backflow. The backflow prevention device 3 includes a rotation rod 31, a fixed plate 32 and a rotation plate 33. The rotation rod 31 is a round rod-shaped structure with a horizontal axis. Two rotation rods 31 are provided and are respectively rotatably arranged in two rotation grooves 21. The fixed plate 32 is a semicircular plate-shaped structure, and the fixed plate 32 is fixedly arranged on the inner wall of the through hole 2. The rotation plate 33 is a semicircular plate-shaped structure, and the rotation plate 33 is rotatably arranged in the through hole 2. The side walls of the two rotation rods 31 close to each other are fixed to the rotation plate 33, and the side wall of the rotation plate 33 close to the water inlet pipe 1 abuts against the side wall of the fixed plate 32 away from the water inlet pipe 1.

[0034] When water flows from the water inlet pipe 1 to the water outlet pipe 12, the rotating plate 33 rotates under the action of the water flow, thereby causing the water to flow into the water outlet pipe 12. At this time, when the sprinkler head 13 or the water outlet pipe 12 is blocked, the water flows from the water outlet pipe 12 to the direction of the water inlet pipe 1. During this process, the rotating plate 33 rotates under the action of the water flow. During this process, when the side wall of the rotating plate 33 abuts against the side wall of the fixed plate 32, the fixed plate 32 blocks the rotating plate 33, thereby preventing the rotating plate 33 from rotating. Therefore, the rotating plate 33 blocks the water flow, thereby reducing the probability of backflow.

[0035] In order to reduce the difficulty of the staff's work, a reset groove 22 is opened on the inner wall of the rotating groove 21, and a torsion spring 4 is fixedly arranged on the inner wall of the reset groove 22. The other end of the torsion spring 4 is fixedly arranged on the side wall of the rotating rod 31 away from the rotating plate 33. When the irrigation is stopped, the water flow loses power and stops flowing. At this time, the rotating plate 33 is reset under the action of the torsion spring 4, thereby reducing the difficulty of the staff to reset the rotating plate 33, thereby reducing the difficulty of the staff's work.

[0036] In order to improve the stability of the device, a rounded corner 5 is provided at one end of the rotating plate 33 away from the inner wall of the through hole 2. The rounded corner 5 reduces the probability of the rotating plate 33 colliding with the fixed plate 32 when rotating, thereby improving the stability of the device.

[0037] In order to reduce the probability of backflow, a filter 6 is fixedly arranged on the inner wall of the water inlet pipe 1. The filter 6 filters impurities in the water flow, thereby reducing the probability of the water outlet pipe 12 and the sprinkler head 13 being blocked, thereby reducing the probability of backflow.

[0038] The use principle of a water circulation irrigation system for urban landscape greening in this embodiment is as follows: when the staff needs to water the green plants, when the water flows from the water inlet pipe 1 to the water outlet pipe 12, the rotating plate 33 rotates under the action of the water flow, thereby causing the water to flow into the water outlet pipe 12. At this time, when the sprinkler head 13 or the water outlet pipe 12 is blocked, the water flows from the water outlet pipe 12 to the direction of the water inlet pipe 1. During this process, the rotating plate 33 rotates under the action of the water flow. During this process, when the side wall of the rotating plate 33 abuts against the side wall of the fixed plate 32, the fixed plate 32 blocks the rotating plate 33, thereby preventing the rotating plate 33 from rotating, thereby causing the rotating plate 33 to block the water flow, thereby reducing the probability of backflow.

[0039] Example 2

[0040] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the method of preventing water from flowing backward is different. In this embodiment, when water flows from the water inlet pipe 1 to the water outlet pipe 12, the lower end of the backflow prevention plug 7 is lifted up by the water flow, so that the water flows into the water outlet pipe 12. Subsequently, when the water flows from the water outlet pipe 12 to the water inlet pipe 1, the water flows into the installation groove 23. In this process, since the lower end of the backflow prevention plug 7 abuts against the inner wall of the through hole 2, the backflow plug cannot be lifted up, so that the backflow plug blocks the water flow, thereby reducing the probability of water flowing into the water inlet pipe 1. In this process, since the backflow prevention plug 7 is made of rubber material, the difficulty of the water flow lifting the backflow plug is reduced, thereby reducing the difficulty of the staff's work.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
