Description

Technical Field

[0001] This utility model belongs to the technical field of dust suppression equipment for underground chambers, specifically relating to a protective dust suppression device for underground chambers. Background Technology

[0002] Underground chambers are artificially excavated or naturally existing spatial structures within underground rock and soil masses, widely used in mine shafts, transportation tunnels, hydraulic tunnels, underground powerhouses, and underground military engineering projects. The excavation of underground chambers primarily employs mechanical excavation and blasting excavation. Mechanical excavation is mainly used for soft or homogeneous rock, while when encountering hard rock, explosives are used for blasting to improve excavation efficiency.

[0003] However, blasting inside caverns generates stones and dust, which create a harsh working environment and temporarily prevent work from taking place. Stones also fly erratically and rapidly within the cavern during the explosion, potentially impacting nearby equipment and causing damage to its exterior or even the equipment itself. Currently, the common method to address these issues is to move equipment and personnel away from the blast site, allowing the dust to settle before relocating the equipment to the excavation site. This process is cumbersome and time-consuming, significantly reducing the efficiency of underground cavern excavation.

[0004] Therefore, it is necessary to design a dust protection device for underground chambers to enable dust inside the underground chambers to fall quickly. Utility Model Content

[0005] This invention provides a dust protection device for underground chambers to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dust suppression and protection device for an underground chamber includes: a support assembly including a base; and a dust suppression assembly including a housing, a water pump, a pipe, a nozzle, and a protective cloth. The housing, the water pump, the nozzle, and the protective cloth are all mounted on the base. The input end of the water pump is connected to the housing via the pipe, and the output end of the water pump is connected to the nozzle via the pipe. The nozzle and the protective cloth are located on the same side. The protective cloth has an open structure. The water pump and the housing are located on the top surface of the base.

[0007] As a further improvement to the technical solution, the support assembly also includes a bracket; the bracket is disposed at one end of the base; the nozzle and the protective cloth are disposed on the base via the bracket.

[0008] As a further improvement to the technical solution, the bracket includes multiple telescopic rods; one end of each telescopic rod is connected to the base; the telescopic rods are distributed in parallel at intervals along the circumference; and the multiple telescopic rods are arranged to form a fan shape.

[0009] As a further improvement to the technical solution, the nozzle is connected to the telescopic rod; a through hole is provided on the protective cloth; the output end of the nozzle passes through the protective cloth through the through hole.

[0010] As a further improvement to the technical solution, the protective cloth is detachably connected to the bracket.

[0011] As a further improvement to the technical solution, the protective fabric is made of tear-resistant material.

[0012] As a further improvement to the technical solution, the nozzle is made of stainless steel.

[0013] As a further improvement to the technical solution, the support assembly also includes a protective cover; the protective cover is disposed on the base; the protective cover covers the water pump.

[0014] As a further improvement to the technical solution, the support assembly also includes a walking wheel; the walking wheel is rotatably mounted on the bottom of the base.

[0015] As a further improvement to the technical solution, the support assembly also includes a pull rod; one end of the pull rod is connected to the end of the base away from the protective cloth.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Before blasting, this application involves moving the base to a position a certain distance from the blasting site. Then, the protective fabric is connected to the telescopic end of the telescopic rod, extending the rod to open the protective fabric into a fan-shaped structure. Simultaneously, pads are placed under the wheels to prevent rotation and secure the base. Explosives are remotely detonated, blasting the rock. The opened protective fabric blocks the flying rocks, absorbing their kinetic energy and preventing them from continuing to fly, causing them to fall to the ground. The telescopic rod supports the protective fabric, ensuring it remains open. After all the rocks have landed, a water pump is activated, delivering water from the tank to the nozzles. The nozzles atomize and spray the water, combining with the dust, increasing its weight and causing it to fall quickly, preventing dust from flying and creating a favorable working environment.
