Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to a dust detection device for mines. Background Technology

[0002] A mine is an underground mining facility, typically used to extract resources such as coal and metallic ores. A mine consists of vertical or inclined tunnels and passages, used for transporting ore, providing access points and air circulation, and housing various equipment and machinery. Workers perform mining operations within the mine, including excavation, support, transportation, and ventilation. Mines present numerous safety hazards, such as collapses, toxic gases, and fires. Therefore, workers must adhere to strict safety regulations and operating procedures. Ensuring the safety of workers' lives and property is a crucial task of mine management. Mine dust detection devices are used to monitor dust concentrations in coal mines or other industrial environments. These devices typically use sensors or instruments to measure the content of dust particles in the air to ensure that dust concentrations remain within safe ranges. By monitoring dust concentrations in real time, these devices can help protect workers from dust pollution and potential health risks.

[0003] Current dust detection devices are fixed in position during the detection process, which is a static detection method. Static detection cannot fully cover the entire work area, which may result in inaccurate detection results. Static detection cannot reflect the impact of personnel activities and mechanical operations on dust generation, and cannot provide a comprehensive safety assessment. In addition, adjusting the position of the dust detection device requires moving the fixed structure, which takes a long time. Utility Model Content

[0004] The purpose of this utility model is to provide a mine dust detection device, which has the advantages of being able to adjust the height of the detection device body and drive the detection device body to move back and forth laterally for maintenance, thereby realizing dynamic detection, expanding the detection range, and reducing the difficulty of operation. It solves the problems of small detection range and inconvenience in adjusting the detection position of mine dust detection devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine dust detection device, comprising a base plate, a screw block, a retainer, and a filter screen. A screw sleeve is movably installed on the top of the base plate, and a stud is fixedly installed on the bottom of the retainer. The stud is engaged with the screw sleeve. A lead screw is movably installed on the retainer, and the screw block is engaged with the lead screw. A servo motor is installed on the side of the retainer. A bearing plate is installed on the top of the screw block. Fixing plates are welded to both sides of the top of the bearing plate. Both fixing plates have screw holes, and screw rods are threaded into the inner walls of the two screw holes. Clamping plates are movably installed on opposite ends of the two screw rods. The detection device body is clamped and fixed on opposite sides of the two clamping plates.

[0006] When using the mine dust detection device in this technical solution, the detection device body is placed on top of the support plate. Two handwheels are used to rotate two screws, which rotate and move within the screw holes of two fixed plates. The two screws push two clamping plates to move, clamping and fixing the detection device body. The base plate carries the detection device body into the mine via casters. A lever is used to rotate the screw sleeve, causing the stud to rotate and move within the rotating sleeve. The stud drives the retainer to rise, which in turn drives the detection device body to rise and adjust its height. After the detection device body is adjusted to a suitable height, the servo motor drives the lead screw to rotate through the transmission structure, causing the screw block... Moving on the rotating lead screw, the screw block drives the detection device body to move laterally back and forth via the bearing plate. During the movement, air from inside the mine enters the detection device body through two air inlet pipes. The mesh frame inside the two air inlet pipes prevents large foreign objects from entering the detection device body. The dust inspection mechanism inside the detection device body detects the dust content in the air and transmits the detection data to the central control room through the internal signal transmission mechanism. The air that has completed the detection inside the detection device body is discharged from the air outlet pipe. The filter screen inside the air outlet pipe adsorbs the dust in the air, preventing the dust from continuing to spread into the surrounding air.

[0007] Preferably, the threaded sleeve is provided with handles arranged in a circular array on its outer side. The handles allow the threaded sleeve to be rotated, causing the stud to move within the rotating sleeve. The stud can then raise and lower the retainer, allowing for height adjustment of the retainer.

[0008] Preferably, a fixing sleeve is installed on the top of the base plate on one side of the threaded sleeve, and a fixing rod is installed on the bottom of the retainer on the side of the stud, with the bottom of the fixing rod inserted into the fixing sleeve. The fixing sleeve and the fixing rod limit the position of the retainer, and when the retainer is raised or lowered, it drives the fixing rod to move inside the fixing sleeve, preventing the retainer from shaking.

[0009] Preferably, the servo motor transmission structure is fixedly connected to the lead screw. The servo motor drives the lead screw to rotate through the transmission structure, and the screw block moves on the rotating lead screw.

[0010] Preferably, a slider is installed at the bottom of the screw block, and a groove is formed at the bottom of the cage, with the slider and the groove slidably connected. The slider provides support to the screw block, and the screw block can slide inside the cage via the slider and the groove.

[0011] Preferably, two positioning rods are symmetrically installed on the inner side of the cage, and two positioning holes are symmetrically opened on the screw block. The two positioning rods pass through the two positioning holes. The positioning rods and positioning holes limit the movement of the screw block. When the screw block moves on the lead screw, it moves on the two positioning rods through the two positioning holes, making the movement of the screw block on the lead screw more stable and preventing deviation or shaking.

[0012] Preferably, each of the two screws has a handwheel installed at one end facing away from the other. Using the two handwheels, the two screws can be rotated, moving within the screw holes of the two fixed plates, thus driving the two clamping plates to move.

[0013] Preferably, the detection device body has air inlet pipes installed on both sides, and a mesh frame installed inside each air inlet pipe. An air outlet pipe is installed on the top of the detection device body, and an insertion hole is provided on the side of the air outlet pipe through which a filter is inserted. When the detection device body moves laterally back and forth, air from inside the mine enters the detection device body through the two air inlet pipes. The mesh frames inside the two air inlet pipes prevent large foreign objects from entering the detection device body. The air that has completed detection inside the detection device body is discharged through the air outlet pipe. The filter inside the air outlet pipe adsorbs dust from the air, preventing dust from further spreading into the surrounding air.

[0014] Preferably, casters are installed at all four corners of the bottom of the base plate. The base plate can be moved on the ground via the casters, and the movement of the base plate will drive the detection device body to adjust its position.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a stud and a screw block to fix the detection device body to the top of a support plate. The base plate then carries the detection device body into the mine. A lever is used to rotate the screw sleeve, causing the stud to rotate and move within the sleeve. The stud drives the retainer to rise, which in turn raises the detection device body to adjust its height. Once the detection device body is at the appropriate height, a servo motor drives a lead screw to rotate via a transmission structure. The screw block moves along the rotating lead screw, and through the support plate, it drives the detection device body to move laterally back and forth. During this movement, air from inside the mine enters the detection device body through two air inlets. The internal mesh frame of the trachea prevents large foreign objects from entering the detection device. The dust inspection mechanism inside the detection device detects the dust content in the air and transmits the detection data to the central control room through an internal signal transmission mechanism. The air that has completed the detection inside the detection device is discharged from the exhaust pipe. The filter inside the exhaust pipe adsorbs the dust in the air, preventing the dust from spreading further into the surrounding air. This allows for adjustment of the height of the detection device and enables it to move laterally back and forth for maintenance, thereby achieving dynamic detection, expanding the detection range, and reducing the difficulty of operation.

[0029] In this embodiment, by placing the detection device body 11 on top of the support plate 17, two handwheels 9 are used to rotate two screws 27. The two screws 27 rotate and move within the screw holes 26 of the two fixing plates 10, pushing the two clamping plates 16 to move.
