Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression nozzle structures, in particular to a construction dust suppression device with a nozzle quick-detachment mechanism. Background Art

[0002] During construction, dust pollution is a common problem that has serious impacts on the environment and workers' health. In order to effectively control dust, various dust suppression devices have emerged.

[0003] Traditional dust suppression devices are tubular in design, typically employing fixed nozzles on the outside of the pipes. While these devices can reduce dust to a certain extent, they also have some drawbacks. For example, when a nozzle becomes clogged or damaged, replacement and maintenance are cumbersome, requiring the entire sprinkler system to be shut down and the nozzle's connectors to be disconnected from the water pipes before replacement. This lengthy replacement process makes it difficult to meet construction site requirements and compromises dust suppression effectiveness. Therefore, a construction dust suppression device with a quick-release nozzle mechanism is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A construction dust reduction device with a quick-release nozzle mechanism includes a hanging water pipe, a joint group is installed on the end side of the hanging water pipe, the joint group includes a straight-through pipe, the top end of the straight-through pipe is connected to the vertical pipe end, and the top end of the vertical pipe end is inserted and installed with a nozzle group, the nozzle group includes a nozzle, the bottom end of the nozzle is connected to an insert tube, and the insert tube is inserted into the inside of the vertical pipe end, the end of the insert tube is sleeved on the surface of the inner insert tube, and the inner insert tube is connected and fixed to the inner wall of the vertical pipe end.

[0007] Preferably, an inner ring block is connected to the top of the inner wall of the vertical pipe end, and a sealing rubber sleeve is installed on the outer side of the inner ring block. A plurality of annular grooves are equidistantly provided on the inner wall of the sealing rubber sleeve. When the insert is inserted into the interior of the vertical pipe end, the insert can contact the inner wall of the sealing rubber sleeve to ensure the tightness of the insert installed inside the vertical pipe end.

[0008] Preferably, a ring plate is connected to the top side of the insert, and a sealing ring is embedded in the bottom end of the ring plate through a ring groove, and the sealing ring contacts the top surface of the vertical pipe end. When the insert is inserted into the vertical pipe end, the ring plate can contact the top of the vertical pipe end to ensure the stability of the insert.

[0009] Preferably, a filter is installed at the top of the inner tube, and an outer edge is provided on the side of the filter, and the outer edge is laid on the top side of the inner tube. By inserting the filter inside the inner tube, impurities in the water flow can be intercepted to prevent impurities from directly clogging the nozzle hole.

[0010] Preferably, a clamping part is arranged around the outer side of the bottom end of the insert tube, and the clamping part includes a supporting spring, and the supporting spring is fixed to the inner wall of the insert tube through a through hole. A clamping bead is connected to the outer side of the supporting spring, and the clamping bead is embedded in the inner wall of the vertical tube end through a clamping groove. When the insert tube is inserted into the interior of the vertical tube end, the elastic force of the supporting spring can push the clamping bead, so that the clamping bead can be embedded and engaged in the clamping groove of the vertical tube end under force, thereby realizing rapid installation of the insert tube.

[0011] Preferably, a threaded end is provided on the outer side of the top end of the vertical pipe end, and a fixing component is sleeved and installed on the outer side of the top end of the vertical pipe end, and the vertical pipe end can be buckled through the fixing component to ensure the stability of the docking between the vertical pipe end and the insert.

[0012] Preferably, the fixing assembly includes a threaded sleeve, which is threadedly mounted on the outer side of the top end of the vertical pipe. A pressure ring is connected to the inner wall of the top end of the threaded sleeve, and the pressure ring is in contact with the surface of the ring plate. A shift plate is connected around the outer side of the threaded sleeve. When the threaded sleeve is mounted on the surface of the vertical pipe end, the pressure ring can squeeze the surface of the ring plate to ensure the stability of the docking between the ring plate and the vertical pipe end.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting up a nozzle group, the nozzle can be quickly connected and disassembled. Compared with the traditional structure, this device is inserted into the inside of the vertical pipe end through the insertion tube, so that the bottom end of the insertion tube is connected to the inner insertion tube. When the insertion tube collides with the bottom end of the inner wall of the vertical pipe end, the elastic force of the supporting spring can push the card to move and buckle into the card slot on the inner wall of the vertical pipe end, so as to complete the initial disassembly and assembly of the nozzle, ensure the portability of disassembly and assembly, and can be independently and quickly plugged in and replaced after the nozzle is blocked, without stopping the entire sprinkler system, meeting the use needs of the construction site.

[0015] 2. By setting up a joint group and a fixing component, the sealing and stability of the insert tube after installation are guaranteed. This device sets an inner ring block on the inner wall of the vertical pipe end, and sets a sealing rubber sleeve on the outside of the inner ring block. When the insert tube is inserted into the inside of the vertical pipe end, the insert tube contacts the inner wall of the sealing rubber sleeve, thereby ensuring the sealing of the insert tube installation. At the same time, the threaded sleeve is threaded from top to bottom on the outside of the vertical pipe end, and the ring plate is pressed down by the pressure ring to ensure the stability of the insert tube installation.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-4 A construction dust reduction device with a quick-release nozzle mechanism includes a hanging water pipe 1, a joint group 2 is installed on the end side of the hanging water pipe 1, the joint group 2 includes a straight-through pipe 21, the top of the straight-through pipe 21 is connected to a vertical pipe end 22, and a nozzle group 3 is installed on the top of the vertical pipe end 22, the nozzle group 3 includes a nozzle 31, the bottom end of the nozzle 31 is connected to an insert tube 32, and the insert tube 32 is inserted into the inside of the vertical pipe end 22, the end of the insert tube 32 is sleeved on the surface of an inner insert tube 25, and the inner insert tube 25 is connected and fixed to the inner wall of the vertical pipe end 22.

[0024] An inner ring block 23 is connected to the top of the inner wall of the vertical pipe end 22, and a sealing rubber sleeve 24 is installed on the outer side of the inner ring block 23. A plurality of annular grooves are equidistantly formed on the inner wall of the sealing rubber sleeve 24.

[0025] A ring plate 33 is connected to the top side of the insert 32 , and a sealing ring 34 is embedded in the bottom end of the ring plate 33 through a ring groove, and the sealing ring 34 contacts the top surface of the vertical pipe end 22 .

[0026] A filter screen 26 is installed on the top end of the inner insert tube 25 . An outer extension edge is provided on the side of the filter screen 26 , and the outer extension edge is laid on the side of the top end of the inner insert tube 25 .

[0027] A clamping part 35 is arranged around the outside of the bottom end of the insert tube 32, and the clamping part 35 includes a support spring 351, which is fixed to the inner wall of the insert tube 32 through a through hole. A clamping bead 352 is connected to the outside of the support spring 351, and the clamping bead 352 is embedded in the inner wall of the vertical pipe end 22 through a clamping groove.

[0028] A threaded end is provided on the outer side of the top end of the vertical pipe end 22 , and a fixing component 4 is sleeved and installed on the outer side of the top end of the vertical pipe end 22 .

[0029] The fixing assembly 4 includes a threaded sleeve 41, which is threadedly mounted on the outer side of the top of the vertical pipe end 22. A pressure ring 42 is connected to the inner wall of the top of the threaded sleeve 41, and the pressure ring 42 contacts the surface of the ring plate 33. A shift plate 43 is connected around the outer side of the threaded sleeve 41.

[0030] By sleeve-mounting the sealing rubber sleeve 24 on the surface of the inner ring block 23, when the insert tube 32 is inserted into the vertical pipe end 22, the insert tube 32 can contact the inner wall of the sealing rubber sleeve 24, ensuring the tightness of the insert tube 32 installed inside the vertical pipe end 22. The multiple ring grooves on the inner side of the sealing rubber sleeve 24 can effectively prevent water from splashing out. When the insert tube 32 is inserted into the vertical pipe end 22, the ring plate 33 can contact the top of the vertical pipe end 22, ensuring the stability of the insertion of the insert tube 32. At the same time, the sealing ring 34 fills the gap between the ring plate 33 and the vertical pipe end 22, further improving the sealing effect. By inserting the filter screen 26 into the inner insert tube 25, impurities in the water flow can be intercepted to prevent impurities from directly clogging the spray hole of the nozzle 31 and affecting the normal dust reduction effect of the nozzle 31.

[0031] When the screw thread sleeve 32 is inserted into the vertical tube end 22, the elastic force of the supporting spring 351 can push the card bead 352 so that the card bead 352 can be embedded and engaged in the card groove of the vertical tube end 22 under force, realizing the quick installation of the screw thread sleeve 32 and ensuring the convenience of installation. It is installed on the outside of the vertical tube end 22 through the fixing component 4, and the vertical tube end 22 can be buckled through the fixing component 4 to ensure the docking stability between the vertical tube end 22 and the screw thread sleeve 32. When the threaded sleeve 41 is sleeved on the surface of the vertical tube end 22, the pressure ring 42 can squeeze the surface of the ring plate 33 to ensure the docking stability between the ring plate 33 and the vertical tube end 22. The design of the dial plate 43 outside the threaded sleeve 41 can increase the friction when the staff holds the threaded sleeve 41, which is convenient for twisting and rotating the threaded sleeve 41.

[0032] Working principle: According to the attached Figure 2 With attached Figure 3 As shown, when the nozzle 31 is damaged, the staff member holds the threaded sleeve 41 and rotates the threaded sleeve 41 so that the threaded sleeve 41 rotates on the threaded end of the vertical pipe end 22, and then removes the threaded sleeve 41 upwards. At this time, the nozzle 31 is pulled out, so that the nozzle 31 drives the insert 32 to move in the vertical pipe end 22, and the card bead 352 is disengaged from the inside of the card groove of the vertical pipe end 22 under pressure, and then the insert 32 can be disengaged from the surface of the inner insert pipe 25. Then, the nozzle 31 is pulled outward to be pulled out.

[0033] Secondly, according to the attached Figure 3 With attached Figure 4 As shown, after the nozzle 31 is removed, the filter screen 26 can be inserted into the inner insert tube 25, and the new insert tube 32 can be inserted into the vertical pipe end 22. At this time, the insert tube 32 is inserted into the vertical pipe end 22 so that the sealing ring 34 is embedded in the ring groove at the bottom end of the ring plate 33. When the insert tube 32 is inserted and installed, the ring plate 33 can be abutted against the top of the vertical pipe end 22, and the threaded sleeve 41 can be inserted from the top of the nozzle 31. Then, the threaded sleeve 41 can be moved on the threaded surface of the vertical pipe end 22 so that the pressure ring 42 can be abutted and buckled on the surface of the ring plate 33 to ensure the stability of the installation of the nozzle 31.
