TECHNICAL FIELD

[0001] The utility model relates to underground monitoring technical field especially relates to a kind of underground working face monitoring equipment. BACKGROUND

[0002] In the field of underground mining operation, the environment of underground working face is complex and harsh. High humidity environment can cause internal circuit short circuit of equipment, high concentration dust can easily cause wear and tear of key components of equipment, harmful gas can also corrode equipment shell and internal elements, strong mechanical vibration can make equipment parts loose, and electromagnetic interference can affect signal transmission and data processing of equipment. In such an environment, underground working face monitoring equipment shoulders the heavy responsibility of ensuring safety in production and improving operation efficiency. It needs to capture the running state of underground equipment in real time, closely monitor the work of personnel, accurately monitor environmental parameters such as gas concentration, carbon monoxide content, temperature and humidity, so as to timely detect potential safety hazards and take prompt measures. Once the monitoring equipment fails, it will cause safety accidents, resulting in immeasurable personnel casualties and property losses, so there are high requirements for its stability, reliability and protection performance.

[0003] The existing underground working face monitoring equipment mostly adopts a relatively traditional way in mechanical structure and technical principle. In terms of heat dissipation design, fixed heat dissipation holes are generally set to rely on natural convection to realize heat dissipation, and some are also equipped with small fans to assist heat dissipation. In terms of dust prevention, basic sealing is mainly realized by installing rubber sealing rings at the gaps of equipment shell. For the installation of filter plate, it is common to use screws to fix the filter plate at the air inlet or ventilation port position of the equipment to filter the dust in the air. Its technical principle is mainly based on simple mechanical fixation and physical filtration, lacks intelligent and automatic design, and is difficult to adapt to complex underground environment.

[0004] However, these traditional designs have obvious problems. Taking the disassembly of filter plate as an example, the existing screw fixing method requires workers to use screwdrivers, wrenches and other tools to complete the operation when the filter plate needs to be maintained and replaced. However, the working space underground is often very cramped, and the light is also very dim, so using multiple tools to operate is not only very inconvenient, but also frequent screwing can easily cause the screw to slip. This not only makes it difficult to disassemble the filter plate, but also can cause the filter plate to be not firmly installed, which not only consumes a lot of time and manpower, but also can not complete the maintenance and replacement of the filter plate in time, causing dust to enter the equipment, affecting the normal operation of the equipment, reducing the service life of the equipment, and failing to meet the needs of efficient and convenient operation underground. Therefore, a kind of underground working face monitoring equipment is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0031] With reference to Figure 1 - Figure 3 The utility model provides an embodiment: a kind of underground working face monitoring device, camera 1 is fixedly connected with fixed shell 2 on both sides of camera 1, fixed shell 2 selects high-strength aluminum alloy material, not only light in quality, also have excellent corrosion resistance, can effectively resist the erosion of underground humid, dusty and rich in corrosive gas harsh environment.Meanwhile, its unique fin design greatly enhances the heat dissipation effect, ensures that camera 1 can maintain stable working condition when long time high load operation, fixed shell 2 is provided with filter plate 3 inside, filter plate 3 adopts stainless steel material, is made by precision stamping and welding process.Its surface fine filter screen, can efficiently intercept dust, coal cinder and other particulate impurities suspended in underground air, prevent them from entering camera 1 inside, to prolong the service life of equipment, maintain good imaging quality, filter plate 3 is provided with dismounting assembly inside, switch assembly is provided on the outer wall of camera 1;

[0032] Dismounting assembly includes connecting column 11, connecting column 11 outer wall is slidably connected in filter plate 3 inside, limiting groove 4 is opened in filter plate 3 inside, limiting ring 12 is fixedly connected to one end of connecting column 11, limiting ring 12 adopts the steel that is also treated by heat, its outer wall is processed by fine grinding, and is perfectly matched with the inner wall of limiting groove 4, can stably slide in groove, provides accurate guide and limit for the movement of connecting column 11, limiting ring 12 outer wall is slidably connected in limiting groove 4 inside, clamping ball 10 is fixedly connected to the other end of connecting column 11, clamping ball 10 selects wear-resistant alloy material, surface is treated by carburizing quenching, hardness is extremely high, can bear greater friction and extrusion force, its smooth arc surface can slide in the clamping groove in fixed shell 2 inside easily, clamping ball 10 outer wall is slidably connected in fixed shell 2 inside, spring 5 is arranged in filter plate 3, one end of spring 5 is fixedly connected to the outer wall of limiting ring 12, the other end of spring 5 is fixedly connected to the inner wall of limiting groove 4.

[0033] Specifically, when the movable filter plate 3 of the downhole working face monitoring device is used for a long time and accumulates a large amount of dust that needs to be cleaned and maintained, since the clamping ball 10 is arc-shaped, only the filter plate 3 needs to be pulled to move the clamping ball 10 together. After the clamping ball 10 moves, the connecting column 11 is driven to move by the situation, and then the connecting column 11 drives the limiting ring 12 to smoothly slide in the limiting groove 4. At the same time, the limiting ring 12 compresses the spring 5, and when the spring 5 is compressed to a certain extent, the filter plate 3 can be easily removed. After cleaning and maintenance, the filter plate 3 is placed back in position. At this time, the spring 5 rebounds to drive the clamping ball 10 to re-clamp in the fixed shell 2, thereby realizing stable fixation and ensuring that the filter plate 3 continues to play a dustproof role.

[0034] With reference to Figure 1 , Figure 2 and Figure 4 , the switch assembly comprises an electric push rod 9 fixedly connected to the outer wall of the camera 1, a rack 8 fixedly connected to the output end of the electric push rod 9, a rotating disc 13 rotatably connected to the outer wall of the camera 1, a gear ring 7 fixedly connected to the outer wall of the rotating disc 13, the gear ring 7 being engaged with the rack 8, a heat dissipation hole 18 formed in the camera 1, a limiting groove 17 formed in the camera 1, a fixed block 14 fixedly connected to the inside of the rotating disc 13, a moving groove 19 formed in the fixed block 14, a connecting plate 6 fixedly connected to the outer wall of the rotating disc 13, a sealing plate 15 arranged in the rotating disc 13, and a slide column 16 fixedly connected to the both sides of the sealing plate 15, the outer wall of one side of the slide column 16 being slidably connected to the inside of the moving groove 19, and the outer wall of the other side of the slide column 16 being slidably connected to the inside of the limiting groove 17.

[0035] Specifically, in the complex working environment underground, when the device is in an unused state or the temperature underground is low, in order to prevent the device from being damaged by low temperature and dust from entering to affect the performance of the device, the heat dissipation hole 18 needs to be effectively controlled. At this time, the electric push rod 9 can be started to drive the rack 8 to move smoothly. The movement of the rack 8 drives the gear ring 7 to rotate by virtue of the precise engagement relationship between the two, and then drives the rotating disc 13 fixed coaxially with it to rotate. During the rotation of the rotating disc 13, the fixed block 14 fixedly arranged inside rotates synchronously. The rotation of the fixed block 14 makes the moving groove 19 inside rotate, and the rotation of the moving groove 19 cleverly drives the slide column 16 to move horizontally. The movement of the slide column 16 drives the sealing plate 15, so that it can accurately cover or move away from the heat dissipation hole 18. At the same time, the other side of the slide column 16 smoothly slides in the limiting groove 17 to limit the movement of the sealing plate 15, so as to realize the convenient opening and closing of the heat dissipation hole 18 and effectively prevent dust from entering the inside of the device.

[0036] Working principle: when the use time is too long, the movable filter plate 3 can move, the ball 10 is circular arc, thereby driving the ball 10 to move, then through the ball 10 drive connecting column 11 to move, then through the connecting column 11 drive limit ring 12 in the limit groove 4 inside sliding, and compress the spring 5, thereby taking off to clean and maintain, then put it back through the spring 5 rebound drive ball 10 clamping in the fixed shell 2 inside fixed, keep fixed;

[0037] In addition, when the device is not used or the temperature is low, the electric push rod 9 can be started to drive the rack 8 to move, then through the engagement between the rack 8 and the gear ring 7 drive rotating disc 13 to rotate, then through the rotating disc 13 drive internal fixed block 14 to rotate, then through the fixed block 14 drive internal moving groove 19 to rotate, thereby drive the slide column 16 to move, can drive the sealing plate 15 to move, at the same time through the other side of the slide column 16 in the limit groove 17 inside sliding limit, thereby the heat dissipation hole 18 is convenient to open and close, ensure that the dust does not enter.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
