Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a video monitoring device for underground drilling sites in coal mines. Background Technology

[0002] Currently, underground coal mine operations are prone to accidents due to their distance from the surface, complex terrain, and harsh environment. By utilizing remote video monitoring systems, ground monitoring personnel can directly monitor the underground situation in real time. This not only allows for intuitive monitoring and recording of the safety production situation at the underground work site, but also enables the timely detection of potential accidents, preventing them from happening in the first place. Furthermore, it provides relevant first-hand image data for post-accident analysis. Therefore, remote video monitoring systems are an important component of modern mine safety production monitoring systems.

[0003] A drilling site video monitoring device provided in the prior art uses two cameras and a fixing device for mounting the cameras. The fixing device includes a bracket, a rotating mechanism placed on top of the bracket, and a tilt adjustment mechanism. The centers of the two cameras are arranged in a triangular structure with the center of the drilling rig. The cameras cover the drilling rig and the borehole with their monitoring range through the rotating mechanism and the tilt adjustment mechanism. By adjusting the monitoring range of the cameras through the rotating mechanism and the tilt adjustment mechanism, the device can effectively cover the drilling rig and the borehole opening, intuitively monitor and record the safety production situation at the downhole work site, promptly detect potential accidents, prevent them before they occur, and provide relevant first-hand image data for post-accident analysis.

[0004] However, the drilling environment is quite unique. A large amount of dust is generated during drilling operations. This dust can easily accumulate on the surface of the camera, causing the image captured by the camera to become blurry and seriously affecting the monitoring effect. In addition, due to geological conditions and mining activities, rocks often fall from the top of the drilling site. If they hit the camera, they are likely to be damaged, leading to monitoring interruption and failure to obtain critical information about the underground operations in a timely manner.

[0005] Therefore, it is necessary to provide a video monitoring device for underground coal mine drilling sites to solve the above-mentioned technical problems. Utility Model Content

A video monitoring device for underground coal mine drilling sites includes: a chassis 2, a protective frame 21 fixedly mounted on the top of the chassis 2, a drive component 22 fixedly mounted on the bottom of the chassis 21, a turntable 23 fixedly mounted on the output end of the drive component 22, a monitoring component 24 fixedly mounted on the top of the turntable 23, and a mounting bracket 25 fixedly mounted on the top of the turntable 23.

[0031] Buffer assembly 3, which is disposed on the top of the mounting bracket 25;

[0032] Cleaning component 4 is disposed on top of buffer component 3. Cleaning component 4 includes water tank 41, pump body 42, diversion frame 43 and nozzle 44. Pump body 42 is fixedly installed on the inner side of water tank 41, diversion frame 43 is fixedly installed on the bottom of water tank 41, and nozzle 44 is fixedly installed on the bottom of diversion frame 43.

[0033] Two scraping components 5 are provided on the side of the protective frame 21. Each scraping component 5 includes a mounting rod 51 and a scraping blade 52. The top of the mounting rod 51 is fixedly installed on the bottom of the water tank 41, and the scraping blade 52 is fixedly installed on the side of the mounting rod 51.

[0034] The buffer assembly 3 includes a fixed rod 31, a sliding rod 32, a damping rod 33, and a buffer member 34. The sliding rod 32 is slidably connected to the inner side of the fixed rod 31. The bottom of the damping rod 33 is fixedly installed on the inner side of the fixed rod 31, and the top of the damping rod 33 is fixedly installed on the bottom of the sliding rod 32. The buffer member 34 is sleeved on the outer side of the damping rod 33.

[0035] The bottom of the fixed rod 31 is fixedly installed on the top of the mounting bracket 25, and the top of the sliding rod 32 is fixedly installed on the bottom of the water tank 41.

[0036] Multiple support rods 11 are fixedly installed at the bottom edge of the chassis 2, and brackets 1 are fixedly installed at the bottom of each of the multiple support rods 11.

[0037] The output end of the pump body 42 is connected to the interior of the diversion frame 43, and one side of the scraper 52 is attached to the side of the protective frame 21.

[0038] A limiting structure is provided inside the fixed rod 31 to limit the sliding rod 32. In this way, when the fixed rod 31 rotates, it can synchronously drive the sliding rod 32 to rotate.

[0039] The top of the water tank 41 is provided with a water inlet, and a sealing cap is threadedly connected to the top of the water inlet;

[0040] The monitoring component 24, the drive component 22 and the pump body 42 can all be remotely controlled and are all charged by a battery. The monitoring component 24 can also perform remote video transmission.

[0041] The protective frame 21 is made of transparent material. When in use, it not only protects the monitoring component 24, but also allows the monitoring component 24 to capture images of the drilling site.

[0042] The working principle of the video monitoring device for underground drilling sites in coal mines provided by this utility model is as follows:

[0043] When in use, the video monitoring device is placed on the side of the drilling rig so that the monitoring component 24 can capture the drilling direction of the drilling rig. When working, if gravel falls from the top, it will first come into contact with the water tank 41. At the same time as it comes into contact with the water tank 41, the sliding rod 32 in the buffer component 3 will slide in the fixed rod 31. The damping rod 33 and the buffer component 34 work together to buffer the impact force generated by the gravel, reduce the damage to the water tank 41 and the entire device, and protect the monitoring component 24.

[0044] When a lot of dust accumulates on the protective frame 21 of the monitoring component 24 after prolonged use, the user can first start the pump 42 to draw water from the water tank 41 and spray it onto the protective frame 21 through the nozzle 44 at the bottom of the diversion frame 43, thereby washing away the dust on the protective frame 21. At the same time, the user can also start the drive component 22 to drive the turntable 23 to rotate, thereby causing the turntable 23 to drive the mounting bracket 25, the buffer component 3, and the water tank 41 to rotate, and then the water tank 41 to drive the scraping component 5 to move, thereby scraping away the dust on the protective frame 21.

[0045] Compared with related technologies, the video monitoring device for underground coal mine drilling sites provided by this utility model has the following beneficial effects:

[0046] The protective frame 21, drive unit 22, turntable 23, monitoring component 24, mounting bracket 25, buffer component 3, cleaning component 4, and scraping component 5 work together to form a comprehensive monitoring system. During operation, the protective frame 21 blocks some debris and dust, reducing their direct impact on the monitoring component 24. Simultaneously, the cleaning component 4 and scraping component 5 work in tandem. When dust accumulates on the protective frame 21 and affects the monitoring image, the pump 42 draws water from the water tank 41 and sprays it through the nozzle 44. The drive unit 22 rotates the scraping component 5 to remove the dust, ensuring the cleanliness of the protective frame 21 and enhancing the monitoring effect. The buffer component 3 effectively cushions the impact of debris hitting the water tank 41, preventing direct impact on the monitoring component 24 and thus increasing the stability of the drilling site monitoring.

[0051] The working principle of the video monitoring device for underground drilling sites in coal mines provided by this utility model is as follows:

[0052] When adding water to the inside of the water tank 41, open the sealing cap at the top of the water inlet of the water tank 41, and then pour the water into the inner side of the water inlet. The water is then filtered through the filter screen 64 and enters the inner side of the water tank 41, causing impurities to accumulate on the inner side of the filter frame 63. When dealing with the impurities later, simply remove the fixing ring 62 from the top of the retaining ring 61, and the filter frame 63 can be removed from the inner side of the water inlet, making it convenient for the user to clean the impurities.

[0053] Compared with related technologies, the video monitoring device for underground coal mine drilling sites provided by this utility model has the following beneficial effects:

[0054] The structure, consisting of baffle ring 61, fixing ring 62, filter frame 63, and filter screen 64, works together to filter the water added to the water tank 41 during use. Impurities are collected on the inner side of the filter frame 63, thus preventing impurities from accumulating on the inner side of the water tank 41 and facilitating subsequent treatment of impurities by the user.
