[0029] In order to realize the water spraying function, the existing construction dust suppression fence usually adds structures such as nozzles and water tanks on the fence panels, and multiple water supply pipes need to be set up to supply water to each water tank, resulting in a complex structure of the construction dust suppression fence, difficulty in transportation and installation, and low water supply efficiency.

[0030] The utility model proposes a construction dust reduction fence, including a water tank 10, a connecting column 20, a suction pipe 30 and a guardrail 40, a water storage chamber 11 is formed in the water tank 10, and the two side walls of the water tank 10 along the first horizontal direction are respectively provided with through holes 12 and water injection holes, the through holes 12 and the water injection holes are both connected to the water storage chamber 11, the water injection holes are connected to a water injection pipe 13 extending outward from the water tank 10, the water injection pipe 13 can extend into the through hole 12 of a water tank 10 adjacent thereto, and a first card slot 14 extending along the first horizontal direction is provided on the top of the water tank 10; the connecting column 20 is provided with a first card slot 14 extending along the first horizontal direction ... 20 is detachably connected to the top of the water tank 10 and extends vertically, a nozzle 21 is arranged on the top of the connecting column 20, a water delivery cavity is opened in the connecting column 20, and two second card slots 22 are respectively arranged on both sides of the connecting column 20 along the first horizontal direction, and each second card slot 22 extends vertically; the suction pipe 30 is passed through the water delivery cavity and connects the nozzle 21 with the water storage cavity 11; the bottom of the guardrail 40 is engaged with the first card slot 14, and the guardrail 40 can be engaged with the two second card slots 22 of two adjacent connecting columns 20 on both sides along the first horizontal direction.

[0031] See also Figure 1 and Figure 2 , Figure 1 The left and right direction in is the first horizontal direction. Figure 1 The up and down directions in the figure are the vertical directions. The water tank 10 is located at the bottom of the construction dust reduction fence, the connecting column 20 and the guardrail 40 are located above the water tank 10, and the suction pipe 30 is built into the connecting column 20 and connects the nozzle 21 with the water storage chamber 11, so as to supply water to the nozzle 21 through the water storage chamber 11, so that the nozzle 21 sprays water outward to reduce dust. It can be understood that the nozzle 21 is built with a water pump in the prior art, and the water pump is used to absorb water from the water storage chamber 11 and supply water to the nozzle 21. The connecting column 20 is detachably connected to the top of the corresponding water tank 10, and two second card slots 22 are respectively provided on both sides of the connecting column 20 along the first horizontal direction, one of the second card slots 22 is engaged with the guardrail 40 in the construction dust reduction fence, and the other second card slot 22 is engaged with the guardrail 40 in the adjacent construction dust reduction fence. When multiple construction dust suppression fences are installed, multiple water tanks 10 are arranged side by side, wherein the water injection pipe 13 of one water tank 10 extends into the through hole 12 of the water tank 10 adjacent to that side, and the through hole 12 on the other side of the water tank 10 is extended by the water injection pipe 13 of the water tank 10 adjacent to that side, so that the water storage chambers 11 of the multiple water tanks 10 are interconnected. Multiple connecting columns 20 in the multiple construction dust suppression fences are arranged at intervals, and a guardrail 40 is clamped between any two adjacent connecting columns 20, so that the multiple construction dust suppression fences form a complete enclosure structure. It can be explained that the water injection pipe 13 and the guardrail 40 can be made of flexible material, and when the connection direction of two adjacent construction dust suppression fences changes, the water injection pipe 13 and the guardrail 40 remain connected by flexible deformation.

[0032] The construction dust reduction fence proposed by the utility model has a water tank 10 located at the bottom of the construction dust reduction fence. When the water storage chamber 11 of the water tank 10 stores water, the deadweight of the water tank 10 increases, and the center of gravity of the construction dust reduction fence is lowered, which can further improve the stability of the construction dust reduction fence. By arranging a detachable connecting column 20 and a clip-fitting guardrail 40 on the top of the water tank 10, the nozzle 21 is arranged on the top of the connecting column 20, and the suction pipe 30 for supplying water to the nozzle 21 is built into the connecting column 20. The nozzle 21 and the suction pipe 30 can be installed along with the installation of the connecting column 20, and the structure is simple, and transportation and installation are convenient. By respectively opening a through hole 12 and a water injection hole on both sides of the water tank 10 along the first horizontal direction, connecting the water injection pipe 13 at the water injection hole, and the water injection pipe 13 can extend into the through hole 12 of the adjacent water tank 10, the water storage chambers 11 of the multiple water tanks 10 can be connected to each other, and water supply to the multiple water tanks 10 can be achieved by injecting water into the water storage chamber 11 of any water tank 10, thereby effectively improving the water supply efficiency.

[0033] In one embodiment, a sealing assembly 15 is disposed at the through hole 12 , and the sealing assembly 15 can block the through hole 12 , and the sealing assembly 15 can open the through hole 12 when the water injection pipe 13 is inserted.

[0034] It should be noted that when the through hole 12 is not connected to the water injection pipe 13, the sealing assembly 15 covers the through hole 12 to form a barrier to prevent water from flowing out of the through hole 12. When the water storage chambers 11 of the two water tanks 10 need to be connected, the water injection pipe 13 is aligned with the through hole 12 and pressure is applied, and the sealing assembly 15 is deformed or displaced under the pressure, thereby opening the through hole 12 and allowing the water injection pipe 13 to extend into. After the water injection pipe 13 moves out of the through hole 12, the sealing assembly 15 returns to its position and blocks the through hole 12, thereby keeping the through hole 12 sealed. The installation is simple and the sealing of the water tank 10 can be effectively ensured.

[0035] In one embodiment, the sealing assembly 15 is located in the water storage chamber 11, and the sealing assembly 15 includes a sealing cover 151, a connecting rod 152 and an elastic member 153. The connecting rod 152 is connected between the sealing cover 151 and the elastic member 153. The elastic member 153 can be compressed and contracted when the water injection pipe 13 is extended into the through hole 12, so as to pull the connecting rod 152 to drive the sealing cover 151 to move away from the through hole 12; the elastic member 153 can be extended under the action of the elastic restoring force when the water injection pipe 13 extends out of the through hole 12, so as to push the connecting rod 152 to drive the sealing cover 151 to move toward the direction close to the through hole 12 until the through hole 12 is blocked.

[0036] See also Figure 5The sealing cover 151 is connected to the elastic member 153 through the connecting rod 152. The elastic member 153 is in a compressed state and can apply elastic force to the connecting rod 152, so that the sealing cover 151 abuts against the inner wall of the water tank 10 to block the through hole 12; when the water injection pipe 13 extends into the through hole 12, the water injection pipe 13 applies pressure to the side of the sealing cover 151 away from the connecting rod 152, so as to drive the sealing cover 151 and the connecting rod 152 to move in a direction away from the through hole 12, and further compress the elastic member 153, so that the sealing cover 151 is separated from the inner wall of the water tank 10 to open the through hole 12; when the water injection pipe 13 moves out of the through hole 12, the sealing cover 151 and the connecting rod 152 are reset under the action of the restoring force of the elastic member 153, and the sealing cover 151 abuts against the inner wall of the water tank 10 again and blocks the through hole 12. It should be noted that the water injection pipe 13 is arranged in an arc shape, and when the water injection pipe 13 extends into the through hole 12, the water injection pipe 13 abuts against the sealing cover 151 at a certain angle, so that when the water injection pipe 13 abuts against the sealing cover 151, the sealing cover 151 will not block the pipe opening of the water injection pipe 13. Through the coordinated work of the sealing cover 151, the connecting rod 152 and the elastic member 153, the automatic opening and closing function of the through hole 12 is realized, which effectively simplifies the loading and unloading process of the construction dust reduction fence.

[0037] In one embodiment, the sealing assembly 15 further includes a sealing gasket 154 , which is connected to the sealing cover 151 . The sealing gasket 154 is used to be placed between the sealing cover 151 and the inner wall of the water tank 10 when the sealing cover 151 blocks the through hole 12 .

[0038] It can be understood that the sealing gasket 154 is connected to the sealing cover 151 and is used to be placed between the sealing cover 151 and the inner wall of the water tank 10 when the sealing cover 151 blocks the through hole 12, forming an additional sealing layer to ensure the sealing of the through hole 12.

[0039] In one embodiment, the connecting column 20 includes a fixing portion 23 and two clamping portions 24. The water delivery cavity is opened in the fixing portion 23. The two clamping portions 24 are respectively located on both sides of the fixing portion 23 along the first horizontal direction. Each clamping portion 24 forms a second clamping groove 22. The fixing portion 23 is detachably connected to the top of the water tank 10, and one of the clamping portions 24 extends outside the top of the water tank 10.

[0040] See also Figure 4 The two clamping parts 24 are respectively located on both sides of the fixing part 23 along the first horizontal direction, and each clamping part 24 includes a second clamping groove 22 and two groove walls of the second clamping groove 22. The two groove walls in one clamping part 24 extend to the outside of the top range of the water tank 10 in the direction away from the other clamping part 24, and the clamping part 24 can extend into the top of the water tank 10 of the adjacent construction dust reduction fence, so that the second clamping groove 22 in the clamping part 24 is clamped and matched with the guardrail 40 in the adjacent construction dust reduction fence to form a stable enclosure structure.

[0041] In one embodiment, a plurality of spaced-apart plug connectors 231 are disposed at the bottom of the fixing portion 23 , each plug connector 231 extends vertically, and a socket 161 is provided at the top of the water tank 10 corresponding to each plug connector 231 , and each plug connector 231 is plugged into and matched with the corresponding socket 161 .

[0042] See also Figure 3 The shapes and positions of the plug connectors 231 and the corresponding sockets 161 match each other. The connecting column 20 is connected to the corresponding sockets 161 through multiple plug connectors 231 to achieve a detachable connection with the top of the water tank 10. The connection between the connecting column 20 and the water tank 10 is fast and stable, which effectively improves the loading and unloading speed of the construction dust reduction fence.

[0043] In one embodiment, a mounting seat 16 is disposed on the top of the water tank 10 , and each plug hole 161 is opened on the mounting seat 16 and is spaced apart from the water storage chamber 11 .

[0044] It should be noted that a mounting seat 16 is provided at the position corresponding to the fixing portion 23 at the top of the water tank 10, and the mounting seat 16 extends to a certain depth in the water tank 10 to facilitate the opening of the plug hole 161, and when each plug connector 231 is plugged into the corresponding plug hole 161, the mounting seat 16 provides stable support for the fixing portion 23, ensuring a stable connection between the connecting column 20 and the top of the water tank 10. Each plug hole 161 is arranged at intervals from the water delivery cavity, avoiding direct contact between the plug connector 231 and the water storage cavity 11 when the plug connector 231 is inserted into the plug hole 161, preventing the water storage cavity 11 from being contaminated when the plug connector 231 is plugged into the plug hole 161, and ensuring that the water storage cavity 11 has good sealing performance.

[0045] In one embodiment, the spray head 21 is rotatably connected to the top of the connecting column 20 , and a motor for driving the spray head 21 to rotate is also disposed on the top of the connecting column 20 .

[0046] It can be explained that the motor provides power for the rotation of the nozzle 21, so that the nozzle 21 can adjust the direction of water spraying to cover a wider area or reduce dust in a specific area, effectively improving the dust reduction range of the construction dust reduction fence, and can adapt to various complex construction environments.

[0047] In one embodiment, the lower end of the straw 30 extends to the bottom of the water storage chamber 11. It can be understood that the lower end of the straw 30 extends to the bottom of the water storage chamber 11, so that the straw 30 can directly draw water from the lowest point of the water tank 10, thereby ensuring that the water in the water tank 10 is fully utilized and the water supply process is more stable.

[0048] In one embodiment, a liquid level sensor is disposed in the water storage chamber 11 .

[0049] It can be explained that the liquid level sensor is communicatively connected to the external processor. The liquid level sensor monitors the water level inside the water storage chamber 11 and transmits the water level signal obtained by monitoring to the external processor, so as to obtain the water amount in the water tank 10 in real time, facilitate timely water supply or stop of water supply to the water tank 10, ensure the effective dust reduction of the construction dust reduction fence, and effectively improve the intelligence level of the construction dust reduction fence.
