Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, specifically to a water conservancy pipeline cleaning device for water conservancy projects. Background Technology

[0002] Water conservancy pipelines in water conservancy projects are important infrastructures used to transport, regulate and distribute water flow. They are typically used for irrigation, water supply, flood control, power generation and other purposes. The design and construction of water conservancy pipelines must meet a series of technical requirements to ensure smooth, safe and efficient water flow.

[0003] There are many existing water conservancy pipeline cleaning devices. For example, the pipeline cleaning device for water conservancy projects disclosed in patent publication number CN222288226U can quickly clean the inner wall of water conservancy pipelines through the cleaning mechanism. However, when water conservancy pipelines are transported, installed, or subjected to large external temperature differences, the outer wall of the pipeline may be dented and deformed. As a result, the cleaning disc and protective cover of the device will be obstructed when moving in the pipeline, making it impossible to clean the pipeline normally. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water conservancy pipeline cleaning device for water conservancy projects, which can effectively solve the problem that existing devices are inconvenient to clean when pipelines are deformed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a water conservancy pipeline cleaning device for water conservancy projects, comprising:

[0007] The active cleaning component includes a rotary drive component, the outer wall of which is elastically provided with multiple cleaning heads, and a water tray is fixedly installed at one end of the rotary drive component, the outer wall of which is connected to multiple water spray nozzles.

[0008] An expansion drainage assembly includes multiple telescopic tubes arranged in a circumferential array on one side of a rotating drive component. An air bladder is fixedly installed at one end of each telescopic tube, and a hollow box is fixedly installed at the other end of each telescopic tube. A first connecting plate is fixedly installed at the end of the rotating drive component away from the water tray. An elastic cover is fixedly installed between the first connecting plate and the air bladder, and a movable joint is fixedly installed between the first connecting plate and the hollow box.

[0009] The air injection assembly is used to inject air into the airbag.

[0010] Preferably, a plurality of fixed seats are fixedly mounted on the outer wall of the output end of the rotary drive component in a circumferential array. A fixed rod is fixedly mounted on one end of each fixed seat. A sliding sleeve is slidably mounted on the outer wall of the fixed rod. The sliding sleeve is fixedly connected to the cleaning head. A first spring is fixedly mounted between the fixed seat and the sliding sleeve.

[0011] Preferably, a traction disc is fixedly installed at the end of the water pan away from the rotating drive component, and multiple connecting ropes are fixedly installed in a circumferential array at one end of the traction disc. A connector is fixedly installed at one end of each connecting rope. A water pipe is connected to one end of the water pan, and one end of the water pipe passes through the traction disc and is fixedly connected to a water supply device.

[0012] Preferably, a second spring is fixedly installed between the telescopic tube and the hollow box, one end of the hollow box is connected to a vent pipe, one end of the vent pipe is connected to a second connecting plate, and a first one-way valve is embedded in the second connecting plate.

[0013] Preferably, the gas injection assembly further includes a gas injection tank disposed on one side of the second connecting plate. A sliding plate is slidably installed on the inner wall of the gas injection tank. A push-pull rod is fixedly installed on one side of the sliding plate. The push-pull rod is slidably connected to the gas injection tank. Two connecting blocks are symmetrically fixedly installed on the inner wall of the gas injection tank. A second one-way valve is embedded in the inner wall of the connecting blocks.

[0014] Preferably, a card seat is symmetrically fixedly installed on one side of the second connecting plate, and two card blocks are symmetrically fixedly installed on the outer wall of the gas injection tank, and the card blocks are slidably connected to the card seat.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] 1. By working together with the flexible cleaning head and the retractable airbag assembly, the problem of easy jamming when the pipeline is deformed is effectively solved by traditional devices. The cleaning head achieves radial elastic expansion and contraction through a spring mechanism, and the airbag expands by inflation and combines with the flexible deformation of the telescopic tube to dynamically conform to the inner wall of the pipeline. Even in the concave or locally deformed areas of the pipeline, the device can still move smoothly and maintain stable cleaning contact, which significantly improves the reliability of operation under complex working conditions.

[0017] 2. By adopting a cleaning method that combines rotating water spraying with mechanical brushing, the spray nozzles evenly spray high-pressure cleaning water onto the pipe wall, and the high-speed rotating cleaning head achieves all-round cleaning, greatly improving cleaning efficiency. At the same time, the inflated airbags push the wastewater to the pipe outlet during movement, and the elastic cover forms an isolation area to prevent sewage from spreading and polluting the environment. This achieves simultaneous cleaning and drainage, which not only ensures the operation effect but also meets environmental protection requirements. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 5 A water conservancy pipeline cleaning device for water conservancy projects, comprising:

[0028] The active cleaning component 1 includes a rotary drive 101. Multiple cleaning heads 106 are elastically provided on the outer wall of the rotary drive 101. A water tray 107 is fixedly installed on one end of the rotary drive 101. Multiple water spray nozzles 108 are connected to the outer wall of the water tray 107.

[0029] The expansion drainage assembly 2 includes multiple telescopic tubes 205 (the rotary drive 101 uses a DC motor of model YX series) fixedly arranged in a circumferential array on one side of the rotary drive 101. An air bladder 206 is fixedly installed at one end of each telescopic tube 205, and a hollow box 203 is fixedly installed at the other end of each telescopic tube 205. A first connecting plate 201 is fixedly installed at the end of the rotary drive 101 away from the water tray 107. An elastic cover 202 is fixedly installed between the first connecting plate 201 and the air bladder 206. A movable joint 204 is fixedly installed between the first connecting plate 201 and the hollow box 203. The spray nozzle 108 sprays cleaning water onto the inner wall of the pipe, which, together with the rotating cleaning head 106, cleans the inner wall of the pipe.

[0030] Inflation assembly 3 is used to inflate airbag 206.

[0031] Reference Figure 3 Multiple fixed seats 102 are fixedly installed in a circumferential array on the outer wall of the output end of the rotary drive 101. A fixed rod 103 is fixedly installed at one end of the fixed seat 102. A sliding sleeve 105 is slidably installed on the outer wall of the fixed rod 103. The sliding sleeve 105 is fixedly connected to the cleaning head 106. A first spring 104 is fixedly installed between the fixed seat 102 and the sliding sleeve 105.

[0032] Reference Figure 2 A traction disc 113 is fixedly installed at the end of the water pan 107 away from the rotating drive component 101. Multiple connecting ropes 109 are fixedly installed in a circular array at one end of the traction disc 113. A connector 110 is fixedly installed at one end of each connecting rope 109. A water pipe 112 is connected to one end of the water pan 107. One end of the water pipe 112 passes through the traction disc 113 and is fixedly connected to a water supply device. The clean water supplied by the water supply device needs to be mixed with a certain proportion of cleaning agent and clean water for supply and use.

[0033] Reference Figures 4 to 5 A second spring 208 is fixedly installed between the telescopic tube 205 and the hollow box 203. One end of the hollow box 203 is connected to a vent pipe 207, and one end of the vent pipe 207 is connected to a second connecting plate 209. A first one-way valve 210 is embedded in the second connecting plate 209.

[0034] Reference Figure 5 The air injection assembly 3 also includes an air injection tank 301 disposed on one side of the second connecting plate 209. A sliding plate 304 is slidably and airtightly mounted on the inner wall of the air injection tank 301. A push-pull rod 305 is fixedly mounted on one side of the sliding plate 304, and the push-pull rod 305 is airtightly and slidably connected to the air injection tank 301. Two connecting blocks 302 are symmetrically and fixedly mounted on the inner wall of the air injection tank 301. A second one-way valve 303 is embedded in the inner wall of the connecting blocks 302. When the sliding plate 304 moves in one direction on the inner wall of the air injection tank 301, the internal air pressure of the air injection tank 301 decreases, and outside air enters the air injection tank 301 through the second one-way valve 303. When the sliding plate 304 moves in another direction on the inner wall of the air injection tank 301... The internal air pressure of the air injection tank 301 increases, the second one-way valve 303 closes, and the air inside the air injection tank 301 enters the air pipe 207 and the hollow box 203 through the first one-way valve 210. A retainer 306 is symmetrically fixedly installed on one side of the second connecting plate 209, and two retaining blocks 307 are symmetrically fixedly installed on the outer wall of the air injection tank 301. The retaining blocks 307 and retaining blocks 306 are slidably connected. After air is injected into the airbag 206 through the air injection component 3, the air injection tank 301 can be rotated as a whole to make the retaining blocks 307 and retaining blocks 306 misaligned. The air injection tank 301 can then be removed from one side of the second connecting plate 209. This can prevent the air injection component 3 from moving along the inner wall of the pipe, thus avoiding increasing the burden on personnel.

[0035] The working principle of this utility model is as follows:

[0036] By tying the traction rope to the connector 110, the traction rope and water pipe 112 are passed through the inner wall of the pipe. By reciprocatingly pulling the push rod 305, the sliding plate 304 is driven to slide back and forth in the air injection tank 301. Outside air will enter the air injection tank 301 through the second one-way valve 303, and then enter the air pipe 207 and the hollow box 203 through the first one-way valve 210. The air entering the hollow box 203 will be continuously transported to the air bag 206 through the telescopic tube 205, causing the air bag 206 to continuously expand and grow, so as to match and fit the inner wall of the pipe.

[0037] Pulling the traction rope causes the expansion drainage component 2 and the air injection component 3 to move on the inner wall of the pipe. The cleaning head 106 will slide the sliding sleeve 105 on the outer wall of the fixed rod 103 through the elasticity of the first spring 104, so that the cleaning head 106 fits against the inner wall of the pipe. Turning on the rotation drive component 101 drives each sliding sleeve 105 to rotate the cleaning head 106, so that the cleaning head 106 rotates and cleans inside the pipe. By turning on the water supply device, the external water source is transported into the water tray 107 through the water pipe 112, and then sprayed onto the inner wall of the pipe from the spray nozzle 108, which works in conjunction with the rotating cleaning head 106 to clean the inner wall of the pipe.

[0038] When encountering a deformation point, the sliding sleeve 105 slides freely on the outer wall of the fixed rod 103 to avoid getting stuck at the pipe deformation point and being unable to move. The inflated airbag 206 has a certain elasticity, and the telescopic tube 205 can extend and retract. When encountering a pipe deformation point, it can deform and extend accordingly, causing the airbag 206 to deform and maintain a close fit with the inner wall of the pipe, which can also avoid getting stuck.

[0039] It should be noted that during the expansion of the airbag 206, the elastic cover 202 will also deform and expand, thus isolating the movable cleaning component 1 and the expansion drainage component 2. During the spraying of water by the nozzle 108, the moving airbag 206 and elastic cover 202 will move the cleaned water after cleaning, pushing the clean water out of the pipe for unified collection, thus avoiding environmental pollution by the clean water.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
