Description

Technical Field

[0001] This utility model relates to the technical field of vegetation maintenance devices, specifically to a spraying device for vegetation in sponge cities. Background Technology

[0002] A sponge city, simply put, is a city that can absorb water like a sponge. Such a city can retain rainwater to the greatest extent possible. It has a water storage function during heavy rains, which can then be used for subsequent spraying and irrigation of vegetation.

[0003] CN 214784484 U discloses a spraying device for vegetation in sponge cities, comprising a box body with vertical plates fixedly installed on the inner wall of the box body. The box body contains a collection mechanism and an outlet pipe mechanism. A water pump and a high-pressure water pump are fixedly installed on the bottom inner side of the box body. The device uses a filter screen to reduce clogging caused by larger debris entering the filter box. The device is designed to facilitate rainwater filtration and clean debris from the filter box through the coordinated use of a box door, sliding groove, first slider, filter box, handle block, insertion rod, handle, and locking block, reducing the impact of debris on rainwater drainage. The coordinated use of the water pump, high-pressure water pump, suction pipe, drainage pipe, and outlet pipe allows for the drainage of large amounts of rainwater, reducing urban flooding, and the accumulation of small amounts of rainwater for convenient plant irrigation. However, the following problems still exist: 1. The upward orientation of the spray nozzle cannot be changed, making it inflexible in use; 2. With the suction pipe inlet facing upwards, impurities in the water can easily accumulate inside, causing blockage of the suction pipe. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for vegetation in sponge cities that has a reasonable structure and reliable operation, which solves the above problems, avoids clogging of water supply pipes, and allows for adjustment of the water spraying direction, making it flexible in use.

[0005] The technical solution of this utility model is:

[0006] A spraying device for vegetation in sponge cities includes a water storage tank, a filter assembly located on top of the water storage tank, and a water lifting assembly located in the water storage tank. The key technical features are as follows: the filter assembly includes a filter grid fixed to the upper edge of the water storage tank, a positioning cylinder fixed to the center of the lower surface of the filter grid, an annular outer support plate fixed to the upper part of the inner wall of the water storage tank, an annular inner support plate fixed to the outer wall of the positioning cylinder and flush with the annular outer support plate, an annular filter groove fixed between the annular outer support plate and the annular inner support plate, and a filter screen located at the bottom of the annular filter groove. The water lifting assembly includes a lift pump fixed in the positioning cylinder, a lower lift pipe connected to the inlet of the lift pump and inserted into the lower part of the water storage tank, and an upper lift pipe connected to the outlet of the lift pump and passing through the filter grid. The upper end of the upper lift pipe is connected to a retractable flexible pipe, and the other end of the retractable flexible pipe is connected to a nozzle. A telescopic cylinder is provided between the nozzle and the upper lift pipe. A motor is located at the bottom of the water storage tank, and the output end of the motor is connected to a stirring paddle near the lower end of the lower lift pipe.

[0007] The above-mentioned spraying device for vegetation in sponge cities consists of a filter grid plate composed of a central fixed part and a rotatable part hinged to both sides of the central fixed part. The central fixed part is connected and fixed to the upper edge of the water storage tank, and the central fixed part is provided with a positioning through hole corresponding to the upper lifting pipe.

[0008] The above-mentioned spraying device for vegetation in sponge cities has an inclined inner bottom surface of the water storage tank, and a debris sedimentation tank is provided at the lower end of the inclined surface.

[0009] The aforementioned spraying device for vegetation in sponge cities has a liquid level sensor installed on the inner wall of the water storage tank.

[0010] The aforementioned spraying device for vegetation in sponge cities has a drainage pipe on the inner wall of the water storage tank, and a drainage pump connected to the drainage pipe is provided on the outer side of the water storage tank. The outlet pipe of the drainage pump extends to the urban drainage pipe.

[0011] The aforementioned spraying device for vegetation in sponge cities has a funnel-shaped lower end for the lower lifting pipe, with the top of the stirring paddle inserted therein.

[0012] The above-mentioned spraying device for vegetation in sponge cities has a first right-angle connecting seat fixed at the upper end of the upper lifting pipe, a second right-angle connecting seat fixed on the outer wall of the nozzle, and a telescopic cylinder hinged between the first right-angle connecting seat and the second right-angle connecting seat.

[0013] The beneficial effects of this utility model are:

[0014] 1. Because a telescopic cylinder is installed between the nozzle and the upper lifting pipe, the pitch angle of the nozzle can be adjusted through the telescopic cylinder to achieve flexible use.

[0015] 2. The lower end of the lower riser pipe is arranged downwards, and an agitator is placed at its lower end. Before the water enters the lower riser pipe, it is stirred by the agitator, which can break up the debris in it, prevent the debris from clumping together and clogging the lower riser pipe, and avoid damaging the riser pump.

[0016] 3. The filter grille ensures smooth water flow while filtering out larger debris from the water. The filter screen at the bottom of the annular filter tank filters out smaller debris. When debris accumulates, the flip-up part of the filter grille can be opened for cleaning, making it convenient to use. Attached Figure Description

[0020] The present invention will be described in detail with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 As shown, the spraying device for vegetation in sponge cities includes a water storage tank 20, a filter assembly located on top of the water storage tank 20, and a water lifting assembly located in the water storage tank 20.

[0022] The filter assembly includes a filter grid plate 2 fixed to the upper edge of the water tank 20, a positioning cylinder 15 fixed to the center of the lower surface of the filter grid plate 2, an annular outer support plate 3 fixed to the upper part of the inner wall of the water tank 20, an annular inner support plate 6 fixed to the outer wall of the positioning cylinder 15 and flush with the annular outer support plate 3, an annular filter groove 4 fixed between the annular outer support plate 3 and the annular inner support plate 6, and a filter screen 5 disposed on the bottom surface of the annular filter groove 4. In this embodiment, the filter grid plate 2 is composed of a middle fixing part 201 and a flip-up part 202 hinged to both sides of the middle fixing part 201. The middle fixing part 201 is connected and fixed to the upper edge of the water tank 20.

[0023] The water lifting assembly includes a lifting pump 14 fixed in the positioning cylinder 15, a lower lifting pipe 16 connected to the inlet of the lifting pump 14 and inserted into the lower part of the water storage tank 20, and an upper lifting pipe 7 connected to the outlet of the lifting pump 14 and passing through the filter grid plate 2. A retractable flexible pipe 8 is connected to the upper end of the upper lifting pipe 7, and a nozzle 9 is connected to the other end of the retractable flexible pipe 8. A telescopic cylinder 11 is provided between the nozzle 9 and the upper lifting pipe 7. In this embodiment, the middle fixing part 201 of the filter grid plate 2 has a positioning through hole 203 corresponding to the upper lifting pipe 7. A first right-angle connecting seat 12 is fixed to the upper end of the upper lifting pipe 7, a second right-angle connecting seat 10 is fixed to the outer wall of the nozzle 9, and the telescopic cylinder 11 is hinged between the first right-angle connecting seat 12 and the second right-angle connecting seat 10.

[0024] The water storage tank 20 is equipped with a motor 19 at its bottom, and the output end of the motor 19 is connected to a stirring paddle 17 near the lower end of the lower riser pipe 16. In this embodiment, the lower end of the lower riser pipe 16 is funnel-shaped and the top of the stirring paddle 17 is inserted into it.

[0025] The water storage tank 20 has a liquid level sensor 13 installed on its inner wall. A drainage pipe 21 is also installed on the inner wall of the water storage tank 20. A drainage pump 1 connected to the drainage pipe 21 is installed on the outer side of the water storage tank 20. The outlet pipe 22 of the drainage pump 1 extends into the city drainage pipe. The inner bottom surface of the water storage tank 20 is sloped, and a debris sedimentation tank 18 is installed at the lower end of the slope.

[0026] Working principle:

[0027] When in use, the water storage tank 20 is buried below ground level, and the upper surface of the filter screen 2 is flush with or slightly higher than the ground level.

[0028] When it rains, rainwater is filtered through the filter grid 2 and filter screen 5 in sequence before entering the water storage tank 20. When the liquid level sensor 13 detects that the liquid level has reached the upper limit, the drainage pump 1 directs the rainwater in the water storage tank 20 to the city drainage pipe.

[0029] When rainwater needs to be drawn from outside for spraying, first start the motor 19 to drive the agitator 17 to rotate, then start the lift pump 14. The water enters through the lower end of the lower lift pipe 16, and is then sprayed out through the lower lift pipe 16, lift pump 14, upper lift pipe 7, telescopic flexible pipe 8 and nozzle 9. During this process, the pitch angle of the nozzle 9 can be changed by the telescopic cylinder 11.

[0030] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
