Description

Technical Field

[0001] This application relates to the field of dust suppression technology at construction sites, specifically a spray dust suppression device for construction sites. Background Technology

[0002] In order to avoid dust pollution in construction sites, sprinkler systems are often used. By spraying water mist, the dust in the air is combined with the atomized water droplets, which increases the weight of the dust and causes it to settle to the ground. This reduces the dust content in the air and improves the air quality at and around the construction site. In addition, the sprinkler system is usually installed with a PVC protective shell to facilitate the recycling of the aging sprinkler pipes.

[0003] A search revealed that patent CN216986918U discloses an anti-aging, reusable dust suppression spray structure for construction sites. This structure uses first and second protective shells to protect the pipes and spray heads during installation. The first and second protective shells are wall-mounted using external mounting blocks, threaded holes, and bolts, preventing prolonged exposure to sunlight and thus extending their lifespan and allowing for repeated long-term use.

[0004] Although the existing technology can achieve the protection and installation of sprinkler pipes, in the actual use of such devices, the installation of a single set of first and second protective shells requires multiple sets of mounting blocks and threaded holes to be bolted to the top of the wall. The installation is cumbersome and inconvenient for subsequent disassembly and recycling. In addition, the fixed installation height is not very applicable. Utility Model Content

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 5This application provides a dust suppression spraying device for construction sites, including a protective housing 1 and a spraying pipe 2. The spraying pipe 2 includes a through-connected liquid pipe 201 and multiple sets of spray heads 202. Hook blocks 102 are fixedly installed at both ends of the top of the protective housing 1. The hook blocks 102 have through grooves inside. Lateral splicing mechanisms 5 are provided on both sides of the protective housing 1 for lateral splicing. A wall-mounted assembly 4 is provided on the top of the multiple sets of protective housing 1 away from the splicing end. A connecting and reinforcing assembly 6 is provided on the top of the multiple sets of protective housing 1 near the splicing end. The wall-mounted assembly 4 includes a connecting rod 410 and two sets of connecting sleeves 402 that are sleeved together. The connecting rod 410 and the two sets of connecting sleeves 402 form a telescopic structure. The connecting rod 410 is connected through the through groove. The connecting and reinforcing assembly 6 is connected to the two sets of hook blocks 102. The through-slot of the part is connected, and the sprinkler pipe 2 can be stored and placed through the protective shell 1. Multiple sets of protective shells 1 can be spliced ​​and combined through the horizontal docking mechanism 5. The splicing of multiple sets of protective shells 1 can be reinforced by the connecting and reinforcing component 6. At the same time, the wall-mounted component 4 can provide hoisting support for the end of the spliced ​​multiple sets of protective shells 1 (that is, by inserting the connecting rod 410 into the hook block 102 at the top of the protective shell 1). Thus, the device can be installed and used with reduced bolt installation and easy subsequent disassembly and recycling. Furthermore, through the cooperation of the connecting sleeve 402 and the connecting rod 410 in the wall-mounted component 4, the height of the protective shell 1 and the sprinkler pipe 2 can be adjusted by the telescopic adjustment of the connecting rod 410 at the end of the connecting sleeve 402.

[0033] Reference Figure 2 , Figure 4 and Figure 5 In one aspect of this embodiment, the ends of two sets of connecting sleeves 402 are threaded with locking bolts 403 for limiting the contact of the connecting rod 410. The ends of the two sets of connecting sleeves 402 away from the connecting rod 410 are fixedly installed with fixing plates 401 for wall mounting. The connecting rod 410 is U-shaped, and both ends of the connecting rod 410 are fitted inside the connecting sleeves 402. The middle part of the connecting rod 410 is engaged with the through groove inside the hook block 102. When the device is in use, the wall-mounted assembly 4 can be installed in the desired position by the cooperation of the fixing plate 401 and the bolts. The length of the connecting rod 410 can be adjusted by adjusting the tightness of the locking bolts 403.

[0034] Reference Figure 1 , Figure 2 and Figure 5In one aspect of this embodiment, the connecting reinforcement component 6 is a U-bolt, and the transverse docking mechanism 5 includes two sets of sliding plates 510 and multiple sets of through blocks 501 fixedly connected to both sides of the protective housing 1. The sliding plates 510 slide through the through blocks 501, and a connecting block 511 is fixedly installed at one end of the sliding plate 510. A retraction spring 512 is fixedly connected between the connecting block 511 and the through block 501. The U-bolt includes a U-shaped rod that engages with the through groove inside the hook block 102. Limit nuts are threaded to both ends of the U-shaped rod. When this device is in use, the limit nuts are retracted. The contraction of the spring 512 in the reset state can drive the sliding plate 510 to move towards the connecting block 501. Thus, when the two sets of protective shells 1 are spliced, the sliding plate 510 passes through the two sets of connecting blocks 501 on the sides of the two sets of protective shells 1, assisting the horizontal splicing of multiple sets of protective shells 1 and providing a certain amount of reinforcement support when the multiple sets of protective shells 1 are spliced. When the two sets of protective shells 1 are connected, the connection of the reinforcement component 6 at the joint of the hook block 102 at the top of the two sets of protective shells 1 can further reinforce the splicing of multiple sets of protective shells 1.

[0035] Reference Figure 2 , Figure 3 and Figure 4 In one aspect of this embodiment, the protective housing 1 has a through-tube channel 101 for the liquid pipe 201 to pass through, and a plurality of slots 103 for the spray heads 202 to pass through are provided on one side of the protective housing 1. A limiting component 3 for limiting the liquid pipe 201 is installed inside the protective housing 1, and a fiber cotton layer 7 is bonded to the inner wall of the protective housing 1. When the device is in use, the liquid pipe 201 can be protected and placed through the protective housing 1, and a plurality of spray heads 202 can pass through the slots 103 to spray the outside. In this process, the fiber cotton layer 7 on the inner wall of the through-tube channel 101 can effectively prevent the liquid pipe 201 from rigidly colliding with the protective housing 1, and can also play a role in heat preservation and sound absorption during use.

[0036] Reference Figure 2 and Figure 4 In one aspect of this embodiment, the limiting component 3 includes a threaded interface 301 opened on the top of the protective housing 1 and a downward pressing arc plate 311 located inside the protective housing 1. A threaded rod 310 is rotatably connected to the top of the downward pressing arc plate 311. The threaded rod 310 is threadedly connected to the threaded interface 301. When the device is in use, by rotating the threaded rod 310, the threaded rod 310 and the threaded interface 301 can be driven to move, thereby driving the downward pressing arc plate 311 to move up and down in the pipe passage 101 inside the protective housing 1. By controlling the downward pressing arc plate 311 to move down and abut against the upper surface of the liquid passage 201, the limiting of the liquid passage 201 inside the protective housing 1 can be completed.

[0037] Working principle: When using this construction site dust suppression spraying device, the spray pipe 2 should first be horizontally inserted into multiple sets of protective housings 1. The multiple sets of protective housings 1 are then spliced ​​together using the horizontal docking mechanisms 5 on both sides of the protective housings 1 (i.e., the contraction of the spring 512 in its reset state causes the sliding plate 510 to move towards the connecting block 501, thus allowing the sliding plate 510 to pass through the two connecting blocks 501 on the sides of the two sets of protective housings 1 during splicing, assisting in the horizontal splicing of the multiple sets of protective housings 1). During this process, the threaded rod 310 at the top of the protective housing 1 is rotated... This can drive the downward pressure arc plate 311 to move down and abut against the spray pipe 2 inside the protective housing 1, so as to complete the pre-assembly of the device before use. When the device is installed and used, the connection and reinforcement component 6 can be inserted at the hook block 102 at the top of the two sets of protective housings 1 to reinforce the splicing of multiple sets of protective housings 1. Furthermore, by using the wall-mounted component 4 (that is, by inserting the connecting rod 410 into the hook block 102 at the top of the protective housing 1 and installing the wall-mounted component 4 to the required position through the cooperation of the fixing plate 401 and the bolt), the protective housing 1 of the device spliced ​​and assembled can be hoisted and placed.
