Description

Technical Field

[0001] This utility model relates to the field of ecological restoration engineering technology, specifically to an ecological restoration spraying device. Background Technology

[0002] In ecological restoration projects, irrigation systems are key infrastructure for ensuring the survival and growth of vegetation. Traditional greening irrigation systems typically consist of multiple components connected in series, including sprinkler kits (including rotating sprinklers, atomizing sprinklers, etc.), poles (made of metal or PVC), capillary tubes, branch pipes, and main pipes. The working principle is as follows: the main pipe supplies water through a water pump or municipal pipe network, which is then distributed to the capillary tubes through the branch pipes, and finally sprayed onto the target area through the sprinklers supported by the poles.

[0003] However, traditional systems have the following technical drawbacks: Redundant components and high material costs: It requires independent components such as nozzles, poles, and capillaries, and each component needs to be assembled with connectors such as elbows, tees, and straight connectors. The material cost of a single system accounts for more than 60% of the total cost. Installation is complicated and labor-intensive: processes such as the heat fusion connection between the capillary tube and the branch pipe, and the threaded connection between the nozzle and the station rod require professional tools. The installation time is about 8-12 man-hours per hectare of irrigation area, resulting in significant labor costs. Poor structural stability: The support poles are mostly fixed by insertion, which makes them prone to tilting and falling over in soft soil or slope areas; the connection between the capillary tube and the branch pipe is prone to detachment due to water pressure fluctuations, with a leakage rate as high as 15% to 20%; Adaptability limitations: Traditional nozzles have a fixed flow rate, making it difficult to match the water requirements of different vegetation (such as herbs and shrubs), and atomizing nozzles are prone to clogging, requiring a short maintenance cycle (approximately 15 to 30 days / time).

[0004] To address the aforementioned issues, this invention proposes an integrated spraying device that simplifies materials, facilitates installation, and stabilizes operation through structural optimization, thereby reducing the overall cost of ecological restoration projects. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ecological restoration spraying device, comprising a main pipe connection unit for providing water source transportation, a water supply pipeline unit for connecting a water source diversion component on the side of the main pipe connection unit, and a water storage spraying unit for storing water and continuously spraying it outward at one end of the water supply pipeline unit.

[0006] As a further improvement to the above solution, the main pipe connection unit includes a main pipe, a bypass valve on the side of the main pipe, and a valve handle on the side of the bypass valve.

[0007] Through the above technical solution, a 32mm diameter installation hole is opened on the side wall of the main pipeline to embed a UPVC external thread socket bypass valve. The valve body has an outer diameter of 32mm and a socket depth of 20mm. It is sealed with hot melt adhesive and fixed with stainless steel clamps to ensure the connection strength with the main pipe. The water outlet of the bypass valve is directly connected to the external thread interface of the water supply pipeline unit through the internal thread. A sealing groove is set on the inner wall and a built-in nitrile rubber O-ring is used to achieve double sealing.

[0008] As a further improvement to the above scheme, the water supply pipeline unit includes a branch pipe threaded to one end of the bypass valve.

[0009] Through the above technical solution, the diversion pipe adopts hot-dip galvanized seamless steel pipe, with a length of 1.5m, an outer diameter of 32mm, and a wall thickness of 3.5mm. The inner wall is treated with an anti-corrosion coating of epoxy resin and polyethylene composite layer, which can withstand water pressure ≥1.0MPa. Its upper end pipe port is fixed to the bottle port of the water storage spray unit by argon arc welding, while the lower end is machined with an external thread interface and equipped with a polytetrafluoroethylene sealing tape. At the same time, the bottom end of the diversion pipe is 90° elbow and threaded to the corresponding end interface of the bypass valve.

[0010] As a further improvement to the above solution, the water storage spray unit includes a cylinder set at the top of the diversion pipe, and a variable diameter interface is provided at the bottom of the cylinder, which is fixed to the interface at the top of the diversion pipe.

[0011] The above technical solution uses an inverted water bottle made of 304 stainless steel, which is cylindrical with a total height of 30cm and a capacity of 500mL, ensuring that it can store a sufficient amount of water.

[0012] As a further improvement to the above scheme, the side circumferential array of the cylinder is provided with multiple sets of spraying mechanisms, each set of spraying mechanisms including spray holes opened vertically in an array on the side of the cylinder.

[0013] With the above technical solution, the diameter of the spray holes is 0.5cm, and the holes are distributed in a matrix pattern with a horizontal spacing of 2cm and a vertical spacing of 2cm to form a uniform spray grid.

[0014] Furthermore, no holes are made within 4cm above the bottle mouth and within 2cm below the bottle bottom to prevent water from flowing directly onto the ground or along the bottle wall. At the same time, a reducing interface is opened at the center of the lower end. The upper diameter is 32mm and is welded to the bottle body, while the lower diameter is 25mm and is connected to the water supply pipeline unit. The inner wall of the interface is chamfered at 30° to reduce water flow resistance.

[0015] As a further improvement to the above solution, an auxiliary unit is provided on the water storage spray unit. The auxiliary unit includes a sealing cover threaded onto the cylinder, and a sealing mechanism is fixed inside the sealing cover.

[0016] The sealing mechanism includes a retaining ring movably connected to the inside of the sealing cover interface. A silicone membrane can be provided on the side of the retaining ring. A screw is threadedly connected to the side of the retaining ring. One end of the screw passes through the silicone membrane and is fixed at the corresponding position inside the sealing cover.

[0017] Through the above technical solution, the diameter of the retaining ring matches the inner diameter of the sealing cap. The retaining ring presses the edge of the silicone membrane tightly against the inside of the sealing cap and fixes it with screws, thus achieving a stable connection between the silicone membrane and the sealing cap. Moreover, the silicone membrane has high elasticity. Under the action of gravity, the silicone membrane is stretched and sinks, causing pressure to be generated inside the cylinder.

[0018] As a further improvement to the above solution, a weight-increasing mechanism is provided on the sealing cover. The weight-increasing mechanism includes a sleeve hole opened on the axis of the sealing cover, a weight-increasing rod is movably sleeved in the sleeve hole, and a limit button is fixed at the top of the weight-increasing rod.

[0019] Through the above technical solution, the weight-increasing mechanism is used to increase the weight, ensure that the silicone membrane is pressed down, and generate pressure inside the cylinder, thereby stably spraying the internal water source out of the spray hole.

[0020] As a further improvement to the above solution, a connecting hole is provided on the side of the sealing cover to communicate with its interior.

[0021] Through the above technical solution, when the silicone membrane rebounds according to the water supply, the air between the top of the silicone membrane and the inside of the sealing cover is discharged or drawn in through the connecting hole.

[0022] When in use, this ecological restoration sprinkler system draws water from the main pipeline and connects to the fire protection network or elevated water tank, and is then supplied by a booster pump. With the bypass valve open, water is delivered into the diversion pipe and continuously flows into the cylinder. At this point, the silicone membrane rebounds upward, and the weight-bearing rod generates an upward displacement force until the water level reaches its limit. Then, the weight of the weight-bearing rod presses down on the silicone membrane, causing it to gradually sink and pressurize the water inside the cylinder. This causes the water inside to be steadily sprayed outward from the sprinkler holes. During the spraying, the water flow spreads in a fan shape, ensuring that the vegetation receives water evenly.

[0023] Compared with the prior art, this utility model provides an ecological restoration spraying device, which has the following beneficial effects: 1. This ecological restoration sprinkler system uses a bypass valve to directly connect the main pipe and the branch pipe. A cylinder with spray holes is installed above the branch pipe. Under the pressure of the water flow inside the cylinder, water is sprayed evenly from the spray holes. This integrates water storage, distribution, and spraying functions into a single interface, reduces intermediate connecting parts, improves installation efficiency and operational reliability, and thus achieves cost reduction and efficiency improvement in the irrigation system.

[0024] 2. This ecological restoration spraying device uses an auxiliary unit that can reciprocate to move above the cylinder, and a weight-increasing rod in conjunction with a silicone membrane to achieve spraying inside the cylinder. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] Please see Figure 1 - Figure 4 As shown, the ecological restoration spraying device proposed in this embodiment includes a main pipe connection unit 1 for providing water source transportation, a water supply pipeline unit 2 for connecting a water source diversion component on the side of the main pipe connection unit 1, and a water storage spraying unit 3 for storing water and continuously spraying it outward at one end of the water supply pipeline unit 2.

[0029] Furthermore, the main pipe connection unit 1 includes a main pipe 11, a bypass valve 12 on the side of the main pipe 11, and a valve handle 121 on the side of the bypass valve 12.

[0030] More specifically, the main pipe 11 has a 32mm diameter mounting hole on its side wall to insert a UPVC external thread socket bypass valve 12. The valve body has an outer diameter of 32mm and a socket depth of 20mm. It is sealed with hot melt adhesive and fixed with stainless steel clamps to ensure the connection strength with the main pipe. The outlet of the bypass valve 12 is directly connected to the external thread interface of the water supply pipeline unit through internal thread. A sealing groove is set on the inner wall and a built-in nitrile rubber O-ring is used to achieve double sealing.

[0031] Furthermore, the water supply pipeline unit 2 includes a diversion pipe 21 threadedly connected to one end of the bypass valve 12.

[0032] More specifically, the diversion pipe 21 is made of hot-dip galvanized seamless steel pipe, with a length of 1.5m, an outer diameter of 32mm, and a wall thickness of 3.5mm. The inner wall is treated with an anti-corrosion coating of epoxy resin + polyethylene composite layer, which can withstand water pressure ≥1.0MPa. Its upper end is fixed to the bottle mouth of the water storage spray unit by argon arc welding, while the lower end has a machined external thread interface and is equipped with a polytetrafluoroethylene sealing tape. At the same time, the bottom end of the diversion pipe 21 is a 90° bend and is threaded to the corresponding end interface of the bypass valve 12.

[0033] Furthermore, the water storage spray unit 3 includes a cylinder 31 disposed at the top of the diversion pipe 21, and a variable diameter interface 32 disposed at the bottom of the cylinder 31, which is fixed to the interface at the top of the diversion pipe 21.

[0034] More specifically, the cylinder 31 is an inverted water bottle made of 304 stainless steel, cylindrical in shape, with a total height of 30cm and a capacity of 500mL, ensuring that it can store a sufficient amount of water.

[0035] Furthermore, the side circumferential array of the cylinder 31 is provided with multiple sets of spray mechanisms 33, each set of spray mechanisms 33 including spray holes 331 opened vertically in the side of the cylinder 31.

[0036] More specifically, the nozzles 331 have a diameter of 0.5 cm, and the nozzle positions are distributed in a matrix pattern with a horizontal spacing of 2 cm and a vertical spacing of 2 cm to form a uniform spray grid.

[0037] Furthermore, no holes are made within 4cm above the bottle mouth and within 2cm below the bottle bottom to prevent water from flowing directly onto the ground or along the bottle wall. At the same time, a reducing interface is opened at the center of the lower end. The upper diameter is 32mm and is welded to the bottle body, while the lower diameter is 25mm and is connected to the water supply pipeline unit. The inner wall of the interface is chamfered at 30° to reduce water flow resistance.

[0038] Furthermore, the water storage spray unit 3 is provided with an auxiliary unit 4, which includes a sealing cover 41 threadedly connected to the cylinder 31, and a sealing mechanism 42 fixed inside the sealing cover 41.

[0039] The sealing mechanism 42 includes a retaining ring 421 movably connected to the inner side of the interface of the sealing cover 41. A silicone membrane 422 can be provided on the side of the retaining ring 421. A screw 423 is threadedly connected to the side of the retaining ring 421. One end of the screw 423 passes through the silicone membrane 422 and is fixed at the corresponding position inside the sealing cover 41.

[0040] More specifically, the diameter of the retaining ring 421 matches the inner diameter of the sealing cover 41. The retaining ring 421 presses the edge of the silicone membrane 422 against the inner side of the sealing cover 41 and fixes it with screws 423, so as to achieve a stable connection between the silicone membrane 422 and the sealing cover 41. The silicone membrane 422 has high elasticity. Under the action of gravity, the silicone membrane 422 is stretched and sinks, which generates pressure inside the cylinder 31.

[0041] Furthermore, a weight-increasing mechanism 43 is provided on the sealing cover 41. The weight-increasing mechanism 43 includes a sleeve hole 431 opened on the axis of the sealing cover 41, and a weight-increasing rod 432 is movably sleeved in the sleeve hole 431. A limit button 433 is fixed at the top of the weight-increasing rod 432.

[0042] More specifically, the weight-increasing mechanism 43 is used to increase the weight, ensuring that the silicone membrane 422 is pressed down, thereby generating pressure inside the cylinder 31, and thus stably spraying the internal water source out of the spray hole 331.

[0043] It should be further explained that by lowering the weight-increasing rod 432, the silicone membrane 422 is pushed down, causing it to sink, thereby generating pressure inside the cylinder 31. When the water supply is relatively large, the weight-increasing rod 432 will move upward and then descend again. At the same time, when the weight-increasing rod 432 moves, the limit button 433 indicates that the weight-increasing rod 432 has disengaged from the sleeve hole 431.

[0044] Furthermore, the side of the sealing cover 41 is provided with a communication hole 44 that communicates with its interior.

[0045] More specifically, when the silicone membrane 422 rebounds according to the water supply, the air between the top of the silicone membrane 422 and the inside of the sealing cover 41 is discharged or drawn in through the connecting hole 44.

[0046] The working principle of the ecological restoration sprinkler device proposed in this embodiment is as follows: During use, water is drawn from the main pipeline 11 and connected to the fire protection network or high-level water tank and supplied by a booster pump. With the bypass valve 12 open, water is delivered into the diversion pipe 21. As the water source is continuously delivered, it flows into the cylinder 31. At this time, the silicone membrane 422 rebounds upward, and the weight-adding rod 432 generates an upward displacement force until the water level reaches the limit. At this time, the weight of the weight-adding rod 432 presses down on the silicone membrane 422, causing the silicone membrane 422 to gradually sink and pressurize the water source in the cylinder 31. This causes the water source inside to be stably sprayed outward from the sprinkler hole 331. During the spraying, the water flow spreads in a fan shape, ensuring that the vegetation receives water evenly.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
