Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a dust suppression sprayer for building construction. Background Technology

[0002] During construction, a large amount of dust is often generated, which not only seriously affects the air quality at the construction site and endangers the health of construction workers, but also spreads to the surrounding environment, causing many inconveniences to the lives of nearby residents. In order to effectively control construction dust, dust suppression sprayers have become one of the essential dust suppression equipment at construction sites.

[0003] The existing technology has the following drawbacks: In terms of water pipe connection, the assembly and disassembly process of water pipes for some sprayers is cumbersome and complicated, making it difficult to flexibly adjust the water pipe layout according to the actual layout of the construction site and the needs of different stages. Moreover, storage is also troublesome, consuming manpower and time. In terms of nozzle protection, some sprayers lack effective dust prevention measures. The nozzles are exposed to the dusty construction environment for a long time, which makes them easily contaminated by dust, thereby affecting the spraying effect, shortening the service life of the nozzles, and increasing equipment maintenance costs. Therefore, a dust prevention sprayer for construction is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figures 1-3This utility model provides an embodiment of a dust suppression sprayer for construction, comprising a water pipe 1, a fixing ring 2 fixedly connected to the right side wall of the water pipe 1, an annular groove 3 formed on the inner wall of the fixing ring 2, an opening in the annular groove 3 allowing an L-block 8 to enter and exit the annular groove 3 through the opening, a limit component provided on the inner wall of the fixing ring 2, a rotating ring 7 rotatably connected to the left side wall of the water pipe 1, an L-block 8 fixedly connected to the left side wall of the rotating ring 7, the shape of the L-block 8 being the same as the annular groove 3, allowing the L-block 8 to move along the inner wall of the annular groove 3, a sealing pipe 9 fixedly connected to the left side wall of the water pipe 1, and a nozzle 10 provided at the top of the water pipe 1, through which water is sprayed out in a mist, reducing the spread of dust during construction, and a protective component provided on the outer wall of the nozzle 10.

[0035] The limiting component includes a wedge 5, which is slidably connected to the inner wall of the fixed ring 2. The wedge 5 is inclined, and when the inclined surface is squeezed, the wedge 5 will move. The inner side wall of the wedge 5 is elastically connected to the fixed ring 2 through a return spring 4. A guide rod 6 is slidably connected to the inner wall of the wedge 5. The guide rod 6 allows the wedge 5 to move laterally, and the movement trajectory will not deviate.

[0036] Reference Figure 1 , Figure 6 and Figure 7 The protective assembly includes a connecting block 11, which primarily supports and connects the entire baffle 14. The outer wall of the connecting block 11 is elastically connected to a rod 13 via a positioning spring 12. The inner wall of the connecting block 11 is rotatably connected to the baffle 14, which can shield the nozzle 10 from dust blockage. The outer wall of the connecting block 11 is fixedly connected to one end of the positioning spring 12. When the rod 13 moves outward, it stretches the positioning spring 12. Upon resetting, the spring force of the positioning spring 12 returns the rod 13 to its original position. The other end of the positioning spring 12 is fixedly connected to the inner side wall of the rod 13. The rod 13 passes through and slides on the inner wall of the connecting block 11. The connecting block 11 has a corresponding slot for the rod 13, allowing the rod 13 to move along the connecting block 11. The rod 13 is inserted into the lower outer wall of the baffle 14. Figure 7 As shown, the baffle 14 has a slot corresponding to the insert rod 13. There are two slots on the baffle 14, which are symmetrically arranged. The lower surface of the baffle 14 is in contact with the top of the nozzle 10.

[0037] Reference Figures 3-5The inner sidewall of wedge 5 is fixedly connected to one end of return spring 4. When wedge 5 moves to the left, it will stretch return spring 4. When resetting, the elastic force of return spring 4 will carry wedge 5 to reset. The other end of return spring 4 is fixedly connected to the left sidewall of fixed ring 2. Guide rod 6 is fixedly connected to the left sidewall of fixed ring 2. The left sidewall of sealing tube 9 is in contact with the right sidewall of water pipe 1. The left end of sealing tube 9 is made of rubber material, which can be used to seal the water pipe 1 by contacting the right sidewall of water pipe 1. The outer wall of wedge 5 is in contact with the outer wall of L block 8. L block 8 can be blocked by wedge 5 to prevent it from moving. Wedge 5 is inserted into the inner wall of ring groove 3. The right sidewall of fixed ring 2 is in contact with the left sidewall of rotating ring 7.

[0038] Working principle: When multiple water pipes 1 need to be assembled, first rotate the rotating ring 7 with block L 8 so that block L 8 aligns with the opening of the annular groove 3. Then insert block L 8 into the opening of the annular groove 3. Then rotate the rotating ring 7 with block L 8, allowing block L 8 to move along the inner wall of the annular groove 3. During the movement, block L 8 will press against the inclined surface of wedge 5, causing wedge 5 to move to the left and stretch the return spring 4. When wedge 5 is no longer pressed, the reverse elastic force of the return spring 4 will move wedge 5 to the right to reset it, allowing wedge 5 to move to the right and block block L 8, preventing it from moving. This completes the assembly of the entire water pipe 1. When the water pipe 1 needs to be disassembled and stored, simply move wedge 5 to the left and stretch the return spring 4 so that wedge 5 does not block the movement of block L 8. Then rotate the rotating ring 7 in the opposite direction with block L 8 to the opening of the annular groove 3. Finally, allow block L 8 to be removed from the opening of the annular groove 3.

[0039] When the nozzle 10 is not in use and is being protected from dust, simply move the insert rod 13 outward and stretch the positioning spring 12 to separate the insert rod 13 from the groove on the lower outer wall of the baffle 14. Then rotate the baffle 14 to cover the top of the nozzle 10. When the other groove of the baffle 14 coincides with the insert rod 13, release the insert rod 13 and use the reverse elastic force of the positioning spring 12 to reset the insert rod 13, allowing the insert rod 13 to be inserted into the groove of the baffle 14. If the insert rod 13 needs to be used, simply follow the above steps to ensure that the baffle 14 does not cover the nozzle 10.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
