[0002] Dust generation is a critical environmental issue that urgently needs to be addressed during high-rise building construction. Traditional dust suppression devices often have several shortcomings. For example, when water is drawn directly from a tank for spraying, impurities in the water can easily clog the nozzles, affecting the dust suppression effect and the normal operation of the device. Furthermore, the nozzle angle is usually fixed, making it difficult to flexibly adjust the nozzle's pitch angle according to the actual conditions of the construction site, wind direction, and the dust suppression needs of different construction areas, significantly reducing the dust suppression range and effectiveness. Therefore, a dust suppression device for high-rise building construction that can effectively avoid nozzle clogging and flexibly adjust the nozzle angle is needed to meet the dust suppression requirements of actual construction.

[0006] Preferably, a limiting groove is formed on the top of the fixing plate, and a limiting rod is fixedly connected to the bottom of the card block, with the limiting rod inserted inside the limiting groove.

[0007] Preferably, a sealing ring is provided between the square groove and the fixing plate.

[0011] Preferably, a guide rod is fixedly connected to the surface of the extension rod, and a guide groove is provided on the inner wall of the cylindrical tube, with the guide rod being engaged inside the guide groove.

[0012] Preferably, an angle adjustment assembly is provided between the bottom of the spray gun and the disc. The angle adjustment assembly includes a lead screw, which is fixedly connected to the disc. A sleeve is threaded onto the surface of the lead screw. A rotatable square rod is provided at the top of the sleeve. A rotatable connecting block is provided at the top of the square rod. A sliding groove is provided at the bottom of the spray gun. The top of the connecting block is engaged inside the sliding groove. A handwheel is fixedly connected to the surface of the sleeve.

[0013] Preferably, a handle sleeve is fixedly connected to the outer wall of the handwheel, and the handle sleeve is made of elastic rubber.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the filtration mechanism, in conjunction with components such as a water pump and a water tank, effectively filters the water drawn from the water tank. During use, after the water pump draws water from the tank, the water first enters the filter box through the outlet pipe. The filter box is equipped with a filter screen. When the water flows through the filter screen, impurities in the water are intercepted. The filtered water then flows through the connecting pipe, water pump, and hose to the spray gun. This ensures that the water entering the spray gun and nozzle for spraying is relatively pure, effectively preventing the nozzle from becoming clogged due to impurities, thus avoiding affecting the dust suppression effect. Furthermore, a slag discharge pipe is installed at the bottom of the filter box. When it is necessary to clean the filtered impurities, simply open the pipe cover, and the impurities can be smoothly discharged from the slag discharge pipe. The operation is very convenient, greatly improving the stability and service life of the dust suppression device, ensuring that the dust suppression work can be carried out continuously and efficiently.

[0015] 2. In this utility model, the pitch angle of the nozzle can be flexibly adjusted by cooperating with the angle adjustment component, spray gun, disc, and other components. During use, turning the handwheel causes the sleeve fixedly connected to it to move up and down on the screw. Since the top of the sleeve is connected to the sliding groove at the bottom of the spray gun through a rotatable square rod and a rotatable connecting block, the up and down movement of the sleeve will cause the spray gun to change its pitch angle around the rotatable connection point with the U-shaped frame. In actual high-rise building construction dust suppression applications, operators can adjust the pitch angle of the nozzle in a timely manner according to factors such as different construction heights and dust distribution in different construction areas, making the dust suppression coverage wider and more targeted, thereby significantly improving the dust suppression effect and better meeting the diverse dust suppression needs in the process of high-rise building construction.

The water pumps 6 are fixedly connected by connecting pipes 5. A slag discharge pipe 303 is fixedly connected to the bottom of the filter box 301, and a pipe cover 304 is provided at the bottom of the slag discharge pipe 303. A square groove 23 is opened at the top of the filter box 301, and a slot 24 is opened at the bottom of the square groove 23. A filter screen plate 302 is inserted inside the slot 24. A fixing plate 25 is fixedly connected to the top of the filter screen plate 302. The filter screen plate 302 is fixedly connected to the filter box 301 through the fixing plate 25 and two fixing components 4. The filter box 301 is connected to the water tank 2 through a water outlet pipe 17. The fixing components 4 include a fixing block 401, which is fixedly connected to the side wall of the filter box 301. The fixed block 401 is internally threaded with a screw 402. A knob 403 is fixedly connected to the top of the screw 402. A locking block 404 is rotatably connected to the surface of the screw 402. The locking block 404 abuts against the fixed plate 25. A limit groove 26 is formed on the top of the fixed plate 25. A limit rod 27 is fixedly connected to the bottom of the locking block 404. The limit rod 27 is inserted into the limit groove 26. A sealing ring 28 is provided between the square groove 23 and the fixed plate 25. A transparent observation window 15 is embedded in the side of the water tank 2. Universal wheels 14 with self-locking function are provided at the four corners of the bottom of the base 1. The extension rod 16 is fixed together with the cylindrical rod by the locking assembly 21. The sleeve 211 includes a pin 212 slidably connected inside the sleeve 211. One end of the pin 212 is fixedly connected to a pull rod 214, and the other end of the pull rod 214 is fixedly connected to a handle 215. A spring 213 is sleeved on the surface of the pull rod 214. The two ends of the spring 213 abut against the pin 212 and the end of the sleeve 211 away from the pin 212, respectively. An adjustment hole 13 is opened on the surface of the extension rod 16. The end of the pin 212 away from the pull rod 214 is inserted into the corresponding adjustment hole 13. A guide rod 8 is fixedly connected to the surface of the extension rod 16. A guide groove 19 is opened on the inner wall of the cylindrical tube 7. The guide rod 8 is locked inside the guide groove 19.

[0021] The beneficial effects achieved in this embodiment 1 are as follows: through the cooperation of the filtration mechanism 3 with components such as the water pump 6 and the water tank 2, the water drawn from the water tank 2 is effectively filtered. During use, after the water pump 6 draws water from the water tank 2, the water first enters the filter box 301 through the outlet pipe 17. The filter box 301 is equipped with a filter screen 302. When the water flows through the filter screen 302, impurities in the water are intercepted. The filtered water then flows through the connecting pipe 5, the water pump 6, and the hose 20 to the spray gun 11. This ensures that the water entering the spray gun 11 and nozzle 12 for spraying is relatively pure, effectively preventing the nozzle 12 from becoming clogged due to impurities, thus avoiding affecting the dust suppression effect. Furthermore, a slag discharge pipe 3 is provided at the bottom of the filter box 301. 03. When it is necessary to clean the filtered impurities, simply open the pipe cover 304, and the impurities can be smoothly discharged from the slag discharge pipe 303. The operation is very convenient, greatly improving the stability and service life of the dust suppression device, ensuring that the dust suppression work can be carried out continuously and efficiently. The fixing component 4 cooperates with the fixing plate 25, which on the one hand makes it easy to fix the filter screen 302 firmly, ensuring that its position is stable during the filtration process and can reliably intercept impurities. On the other hand, it is easy to disassemble. When it is necessary to clean or replace the filter screen 302, the fixing plate 25 and the filter screen 302 can be easily removed by reversing the knob 403, which is conducive to the maintenance of the device and ensures that the filtration function is effective for a long time. The limiting rod 27 on the locking block 404 is inserted into the limiting groove 26 on the fixing plate 25. Inside, when the locking block 404 fixes the filter screen 302, it can prevent the locking block 404 from rotating due to vibration or other reasons, so as not to affect the stability of the locking block 404 in fixing the filter screen 302. A sealing ring 28 is set between the square groove 23 and the fixing plate 25. The sealing ring 28 can effectively fill the gap between the square groove 23 and the fixing plate 25 to prevent water containing impurities from leaking out of the gap. Through the transparent observation window 15 embedded in the side of the water tank 2, the construction personnel can intuitively see the water level in the water tank 2 through the observation window 15, so as to know in time whether the water level in the water tank 2 is sufficient, so as to add water in time when the water level is low, ensuring that the dust suppression work will not be interrupted due to water shortage, thus ensuring the continuity of the dust suppression operation. The base 1 has built-in locks at the four corners of the bottom. The casters 14 with locking function enable the entire dust suppression device to have good mobility, allowing for flexible repositioning according to the dust suppression needs of different areas of the construction site. When the device needs to be fixed, the casters 14 can be locked using the built-in locking function, ensuring the device is stably placed in the corresponding position for dust suppression operations. This greatly improves the flexibility and convenience of the device, meeting the dust suppression needs of different locations and stages in high-rise building construction. Through the coordinated operation of the locking component 21, extension rod 16, and adjustment hole 13, when the height of the extension rod 16 needs to be adjusted, pulling the handle 215 disengages the pin 212 from the adjustment hole 13. After the height is adjusted, the pin 212 automatically resets and inserts back into the corresponding adjustment hole 13. This allows for flexible adjustment of the height position of the nozzle 12.This allows for better adaptation to dust suppression needs at different construction heights, expanding the coverage area of ​​the dust suppression device and enhancing its targeting and effectiveness. The cooperation between the guide rod 8 and the guide groove 19 prevents the extension rod 16 from rotating during vertical movement, ensuring that the pin 212 and the adjustment hole 13 are always quickly aligned, thus improving the ease with which the pin 212 can be inserted into the adjustment hole 13.

[0022] Example 2: As Figure 5 As shown, an angle adjustment component 22 is provided between the bottom of the spray gun 11 and the disc 9. The angle adjustment component 22 includes a lead screw 221, which is fixedly connected to the disc 9. A sleeve 222 is threadedly connected to the surface of the lead screw 221. A rotatable square rod 223 is provided at the top of the sleeve 222. A rotatable connecting block is provided at the top of the square rod 223. A sliding groove 18 is provided at the bottom of the spray gun 11. The top of the connecting block is locked inside the sliding groove 18. A handwheel 224 is fixedly connected to the surface of the sleeve 222. A handle sleeve 29 is fixedly connected to the outer wall of the handwheel 224. The handle sleeve 29 is made of elastic rubber.

[0023] The beneficial effects achieved in this embodiment 2 are as follows: By cooperating with the angle adjustment component 22 and components such as the spray gun 11 and the disc 9, the pitch angle of the nozzle 12 can be flexibly adjusted. When in use, the handwheel 224 is turned, and the handwheel 224 drives the sleeve 222, which is fixedly connected to it, to move up and down on the screw 221. Since the top of the sleeve 222 is connected to the slide groove 18 at the bottom of the spray gun 11 through the rotatable square rod 223 and the rotatable connecting block, the up and down movement of the sleeve 222 will drive the spray gun 11 to change the pitch angle around the rotatable connection point with the U-shaped frame 10. In this way, in the actual dust suppression application of high-rise building construction, the operator can adjust the pitch angle of the nozzle 12 in a timely manner according to factors such as different construction heights and dust distribution in different construction areas, so that the dust suppression coverage is wider and more targeted, thereby significantly improving the dust suppression effect and better meeting the diverse dust suppression needs in the construction process of high-rise buildings. The elastic rubber handle sleeve 29 on the outer wall of the handwheel 224 can provide a good grip and facilitate operation.

[0024] The working principle of this embodiment is as follows: In use, the dust suppression device is first moved to the appropriate location for dust suppression during high-rise construction using the casters 14 at the bottom of the base 1. Then, according to the actual construction height requirements, the handle 215 is pulled. The handle 215 drives the pull rod 214, causing the pin 212, which is fixedly connected to one end of the pull rod 214, to slide within the sleeve 211 against the spring force of the spring 213. This allows the pin 212 to disengage from the adjustment hole 13 on the surface of the extension rod 16. Next, the height of the extension rod 16 within the cylindrical tube 7 is adjusted. The guide rod 8 on the surface of the extension rod 16 slides along the guide groove 19 on the inner wall of the cylindrical tube 7, providing guidance and preventing rotation of the extension rod 16 during vertical movement. After adjustment, the handle 215 is released, and the pin 212 disengages. 2. Under the elastic force of spring 213, the extension rod 16 is inserted into the corresponding adjustment hole 13 to fix it, thereby determining the approximate height range of the nozzle 12. Then, the water pump 6 is turned on, and the water pump 6 draws water from the water tank 2. The water first enters the filter box 301 through the outlet pipe 17. When the water flows through the filter screen 302 in the filter box 301, impurities in the water are intercepted by the filter screen 302. The filtered water is then pressurized by the water pump 6 through the connecting pipe 5 and delivered to the spray gun 11 through the hose 20. Finally, it is sprayed out from the nozzle 12 for dust suppression. During the dust suppression process, the operator can adjust the pitch angle of the nozzle 12 by turning the handwheel 224 according to the dust distribution and wind direction of different construction areas. When the handwheel 224 is turned, the sleeve 222 is in The screw 221 moves up and down, causing the rotatable square rod 223, rotatable connecting block, and spray gun 11 to change angles, so that the nozzle 12 can spray at the optimal angle, expanding the dust suppression coverage and improving the dust suppression effect. When the filter screen 302 in the filter box 301 needs to be cleaned after a period of use, the water pump 6 is turned off, and the pipe cover 304 is unscrewed from the slag discharge pipe 303, so that the impurities in the filter box 301 can be discharged from the slag discharge pipe 303. If it is necessary to clean or replace the filter screen 302, rotate the knob 403 in the fixing assembly 4 to make the screw 402 rotate and drive the locking block 404 to disengage from the abutment state with the fixing plate 25. Then, take out the filter screen 302 from the slot 24 and clean the filter screen 302. The impurities are cleaned or replaced. After cleaning, the filter screen 302 is reinstalled back into the filter box 301 via the fixing plate 25. Tighten the knob 403 to make the locking block 404 press against the fixing plate 25 again to fix the filter screen 302. Insert the limiting rod 27 on the locking block 404 into the limiting groove 26 on the fixing plate 25 to continue the dust suppression operation. During the entire use, the construction personnel can check the water level in the water tank 2 at any time through the observation window 15 on the side of the water tank 2. When the water level is low, water should be added in time to ensure the continuous operation of the dust suppression work. When it is necessary to move the device to other construction areas, unlock the locking function of the universal wheels 14 and push the device to move to the designated position. Repeat the above operation procedure to carry out the dust suppression work.This is to meet the dust suppression needs of different stages and areas during the construction of high-rise buildings.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
