[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 4 to 6 This utility model provides an embodiment of a comprehensive dust suppression device for foundation pits, including a pit bottom 1 and a water tank 4, which is designed to store water for dust suppression. A spraying assembly for spraying is fixedly connected to the front of the water tank 4. The spraying assembly includes a water pump 5, which draws water from the water tank 4 for delivery. The external input end of the water pump 5 is fixedly connected to the front of the water tank 4. A connecting pipe 6 is fixedly connected to the output end of the water tank 4 to transport the water source delivered by the water pump 5. Multiple nozzles 7 are fixedly connected to the outside of the connecting pipe 6 to atomize the water flow, increase the contact area with dust, and achieve the dust suppression effect. The outside of the connecting pipe 6 is inside two locking blocks 13, wherein the bottom of the connecting pipe 6 is attached to the top of the bottom locking block 13. A dustproof net 3 is fixedly connected to the top of the two locking rods 2, which blocks the dust generated in the foundation pit through the mesh structure and prevents it from spreading to the surrounding environment. Locking rods 2 are slidably connected to the top of the pit bottom 1 on both sides to support the two sides of the dustproof net 3.

[0035] The bottom of the dustproof net 3 is fixedly connected to an extension assembly for extension support. The extension assembly includes two connecting rods 8, designed to provide good connection capability. By pulling one side of the connecting rod 8, the connecting rod 8 can drive multiple support rods 9 to extend outward. The outer sides of the two connecting rods 8 are on both sides of the bottom of the dustproof net 3, and the outer sides of the two connecting rods 8 are adjacent to the two clamping rods 2. Multiple support rods 9 are rotatably connected to the adjacent outer sides of the two connecting rods 8. Through staggered arrangement, they form a stable support. The outer sides of the multiple support rods 9 are staggered. Multiple rotating columns 10 are rotatably connected to the intersection points of the multiple support rods 9, and multiple movable columns 11 are rotatably connected to the intersection points on both sides of the multiple support rods 9. Rotating columns 10 are rotatably connected to the outer sides of the multiple support rods 9, and movable columns 11 are rotatably connected to the outer sides of the multiple support rods 9. The connection with the support rods 9 allows the support rods 9 to rotate and prevents the support rods 9 from producing static electricity. The bottom of the support column 12 is rotatably connected to the bottom of the rotating column 10. The bottom of the extension component is rotatably connected to the support column 12. After the rotating column 10 rotates, the support column 12 can be adjusted to form a smooth placement space for placing the connecting tube 6. The two outer sides of the support column 12 are slidably connected to the limiting rods 14, which are designed to prevent the two locking blocks 13 from disengaging. At the same time, the limiting rods 14 have multiple rectangular grooves on their outer sides for good positioning. The two limiting rods 14 are slidably connected to the locking blocks 13, which can place the connecting tube 6. The two limiting rods 14 are slidably connected to the fixing rods 15. The support column 16 slides inside the limiting rods 14 to fix the distance between the two locking blocks 13. When the locking rod 2 slides, the dustproof net 3 can drive the connecting rod 8 to slide.

[0036] Reference Figures 1 to 3 Each of the multiple movable columns 11 has a support column 16 rotatably connected to its top. By rotating the movable column 11, the support column 16 can be rotated to adjust the angle. Each of the multiple support columns 16 has two locking columns 17 slidably connected to its exterior. These are designed to engage the dustproof net 3. A connecting column 18 is fixedly connected to the adjacent side of the two locking columns 17. The connecting column 18 is used to connect the two locking columns 17. The exterior of the support column 16 is inside the dustproof net 3. By sliding the two locking columns 17 inside the connecting column 18, the locking columns 17 can engage the dustproof net 3.

[0037] Working Principle: During operation, the equipment first draws dust-suppressing water from the water tank 4 via the water pump 5 and delivers it to the connecting pipe 6. The connecting pipe 6 distributes the water flow to multiple nozzles 7, which atomize the water and spray it into the pit, thereby increasing the contact area between the water and dust to achieve dust suppression. Simultaneously, the dustproof net 3, supported by the clamping rod 2, covers the pit, using its mesh structure to block dust generated within the pit and prevent it from spreading to the surrounding environment. At the bottom of the dustproof net 3, the connecting rod 8 and the support rod 9 work together to expand and contract. When one side of the connecting rod 8 is pulled, it causes multiple support rods 9 to extend outward. The support rods 9 are staggered through the connection of the rotating column 10 and the movable column 11, forming a stable support structure. After the rotating column 10 has rotated, the support column 12 is adjusted to create a smooth placement space for the connecting pipe 6. The limiting rod 14, through the fixing rod 15, engages with the rectangular groove to position the engaging block 13, preventing it from detaching and ensuring the stable placement of the connecting pipe 6. Simultaneously, the fixing rod 15 is slidably connected to the outside of the limiting rod 14, further fixing the distance between the two engaging blocks 13. During equipment operation, the sliding of the clamping rod 2 moves the dustproof net 3, which in turn moves the connecting rod 8, allowing the dustproof net 3 to expand or contract to adapt to the size and shape of the pit, achieving comprehensive coverage and effective control of dust within the pit.

[0038] When the support of the dustproof net 3 needs adjustment, the rotation of the movable column 11 will drive the support column 16 to adjust accordingly. Further rotation of the support column 16 allows for precise angle adjustment, thus accommodating the fixation of the dustproof net 3. Simultaneously, the connecting column 18 ensures the synchronous movement of the two locking columns 17. During operation, the locking column 17 slides along the outside of the support column 16, and through its cooperation with the connecting column 18, it engages the dustproof net 3. This design ensures that the cooperation between the locking column 17 and the support column 16 effectively engages the dustproof net 3, guaranteeing its stability and reliability during use.

[0039] 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.
