Description

Technical Field

[0001] This utility model relates to the field of data acquisition device technology, and more specifically, to a data acquisition device for monitoring water hazards in coal mining faces. Background Technology

[0002] In recent years, with the increasing depth, speed, and intensity of coal mining, the hydrogeological conditions in mines have become increasingly complex, leading to frequent coal mine water inrush and seepage accidents. To prevent water hazards from escalating due to a lack of timely prevention or detection, monitoring of water hazard conditions in mines is implemented.

[0003] Existing water hazard monitoring typically predicts water hazards by detecting water seepage at the coal mining face. In practice, cameras capture images of seepage areas at the face, and the collected data is processed in real time to monitor for water seepage. However, in actual use, cameras are typically mounted on the roof of the mine roadway to capture images of seepage areas. Since water can seep from the mine roadway roof, dripping water easily falls onto the cameras, affecting their usability. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a data acquisition device for monitoring water hazards in coal mining faces, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A grid is installed at the water inlet. The cross-section of the water collection hood is arc-shaped. An adjustable hoisting bracket is provided on the bottom wall of the water collection hood. The high-definition camera is detachably mounted on the hoisting bracket. Drainage pipes located on both sides of the hoisting bracket are provided on the outer wall of the water collection hood.

[0007] Furthermore, a fixing column is provided on the bottom wall of the water collection hood, and a spherical cavity with an opening facing downwards is provided inside the fixing column. A hand-tightening bolt that extends into the spherical cavity is threaded onto the outer wall of the fixing column.

[0008] The hoisting support includes a hoisting rod, the upper end of which is provided with a ball that rotates inside a spherical cavity. Tightening bolts compresses the ball to fix the hoisting rod.

[0009] Furthermore, the hoisting rod includes an upper rod fixedly connected to the ball and a lower rod threadedly connected to the upper rod, with a mounting plate for installing a high-definition camera at the lower end of the lower rod.

[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0028] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0029] This embodiment provides a data acquisition device for monitoring water hazards at coal mining faces, which is used in conjunction with a water hazard monitoring system to monitor water hazards at coal mining faces.

[0030] like Figures 1-4 As shown, in this embodiment, the data acquisition device includes a high-definition camera 100 and mounting components, combined with... Figure 6 As shown, the water hazard monitoring system includes a processing unit, a mine site workstation, and a monitoring room workstation. The data acquisition device uses a high-definition camera 100 to acquire image data of the monitored area in real time. The input end of the processing unit is connected to the data acquisition device to process the image data output by the data acquisition device and send the processing results to the monitoring room workstation and the mine site workstation via the network.

[0031] In practical use, the high-definition camera 100 is installed on the top wall of the mine roadway using a mounting assembly, so that the high-definition camera 100 can acquire images of the monitored area; the processing unit is an existing video analyzer.

[0032] Specifically, the high-definition camera 100 is aimed at the seepage area on the coal mining face to acquire images. The video analyzer analyzes the image sequence of the detection area in real time. When seepage or leakage occurs in the detection area, the brightness and contrast of the corresponding area of ​​the image change. The video analyzer uses this to determine whether there is seepage. If there is seepage, an alarm signal (including an image: referring to an image of the seepage area) is transmitted to the mine site workstation and the monitoring room workstation.

[0033] Among them, the video analyzer is an existing structure that can use video image analysis technologies such as target analysis, fuzzy recognition and dynamic target tracking detection to perform real-time detection of the detection area, so as to achieve real-time monitoring of the water leakage area of ​​the coal mining face, thereby completing the monitoring of water hazards in the coal mining face.

[0034] In this embodiment, the mounting assembly includes a base plate 110, on which a water collection cover 111 is provided. A water inlet 201 is provided on the base plate 110 corresponding to the opening of the water collection cover 111. A grille 310 is installed at the water inlet 201. The cross-section of the water collection cover 111 is arc-shaped. An adjustable hoisting bracket 120 is provided on the bottom wall of the water collection cover 111. The high-definition camera 100 is detachably mounted on the hoisting bracket 120. Drain pipes 112 located on both sides of the hoisting bracket 120 are provided on the outer side wall of the water collection cover 111.

[0035] In actual use, the base plate 110 is fixedly installed on the top wall of the mine roadway by expansion bolts, thereby realizing the fixed installation of the installation components. At this time, the high-definition camera 100 is installed on the hoisting bracket 120, thus realizing the installation of the high-definition camera 100 on the top wall of the mine roadway.

[0036] In this embodiment, by setting up the water inlet 201 and the water collection cover 111, when the base plate 110 is installed on the tunnel roof, the water that leaks from the tunnel roof can flow into the water collection cover 111 through the water inlet 201 and be collected, so as to avoid it dripping directly onto the high-definition camera 100 below the base plate 110, thereby affecting the high-definition camera 100's image acquisition work.

[0037] The grid 310 is fixedly installed inside the water inlet 201, and there is a gap between the upper side of the grid 310 and the upper side of the bottom plate 110. Thus, the grid 310 is used to block the soil that peels off the top wall of the tunnel and prevents it from falling into the water collection hood 111. At the same time, the gap between the two allows water that seeps from the top wall of the tunnel to flow into the water collection hood 111.

[0038] Specifically, by setting up the drain pipe 112, after a large amount of water is collected in the water collection hood 111, the water collected in the water collection hood 111 can be discharged through the drain pipe 112 by opening the drain pipe 112, so as to ensure the long-term use of the installation component.

[0039] Specifically, in order to open and close the drain pipe 112, a plug is threaded to the outer end of the drain pipe 112, and the drain operation can be carried out by removing the plug.

[0040] In this embodiment, the adjustable configuration of the mounting bracket 120 allows for adjustment of the height and orientation of the high-definition camera 100 mounted thereon during actual use. This enables the high-definition camera 100 mounted on the mounting assembly to be suitable for different scenarios, thereby improving the applicability of the data acquisition device.

[0041] In this embodiment, a fixing post 113 is provided on the bottom wall of the water collection cover 111. Specifically, the upper end of the fixing post 113 is fixedly connected to the center position of the bottom wall of the water collection cover 111. A spherical cavity 321 with an opening facing downward is provided inside the fixing post 113. A hand-tightening bolt 130 extending into the spherical cavity 321 is threadedly connected to the outer wall of the fixing post 113.

[0042] The hoisting bracket 120 includes a hoisting rod 121. The upper end of the hoisting rod 121 is provided with a ball 122 that rotates inside a spherical cavity 321. Specifically, the size of the ball 122 is adapted to the spherical cavity 321 so that it can slide and be locked inside the spherical cavity 321 and will not detach from the opening of the spherical cavity 321. The hand-tightening bolt 130 presses the ball 122 to fix the hoisting rod 121.

[0043] In actual use, when the top wall of the mine roadway where the mounting base plate 110 is installed is inclined, the base plate 110 is installed on the top wall of the roadway by expansion bolts so that the base plate 110 is in an inclined state. At this time, by rotating the ball 122 in the spherical cavity 321, the hoisting rod 121 can be better kept in a vertical state. At this time, by tightening the hand-tightening bolt 130, the side wall of the ball 122 is squeezed so that the ball 122 is fixed in the spherical cavity 321, thereby fixing the hoisting rod 121 and keeping it in a vertical state, so as to carry out the vertical installation of the high-definition camera 100 in the mine roadway.

[0044] Specifically, in order to improve the effect of the hand-tightening bolt 130 in fixing the ball 122, a rubber pad is provided at the end of the hand-tightening bolt 130 that presses against the ball 122. The rubber pad increases the friction between the two, thereby improving the effect of fixing the ball 122.

[0045] Specifically, in order to improve the threaded connection strength of the hand-tightening bolt 130 on the fixed post 113, in this embodiment, a connecting sleeve 322 is fixedly provided on the outer wall of the fixed post 113. The connecting sleeve 322 communicates with the spherical cavity 321. The hand-tightening bolt 130 is threadedly connected to the connecting sleeve 322. The connecting sleeve 322 is used to increase the distance between the hand-tightening bolt 130 and the threaded connection, thereby improving the connection strength between the hand-tightening bolt 130 and the fixed post 113.

[0046] In this embodiment, the hoisting rod 121 includes an upper rod 210 fixedly connected to the ball 122 and a lower rod 220 threadedly connected to the upper rod 210. The lower end of the lower rod 220 is provided with a mounting plate 221 for installing the high-definition camera 100.

[0047] In this embodiment, the upper end of the upper rod 210 is fixedly connected to the ball 122, and a threaded cavity with an opening at the lower end is provided inside it. The upper end of the lower rod 220 is threaded into the threaded cavity. Thus, in actual use, the length of the hoisting rod 121 can be adjusted by rotating the distance of the threaded connection of the lower rod 220 in the threaded cavity, so that the distance between the high-definition camera 100 and the water collection cover 111 can be adjusted.

[0048] Specifically, in order to facilitate the rotation of the lower rod 220, in this embodiment, the lower end of the lower rod 220 is fixed to a nut 222 located on the upper side of the mounting plate 221. Thus, in actual use, the operator can hold the upper rod 210 with one hand and turn the nut 222 with the other hand to drive the lower rod 220 to rotate in the threaded cavity, so as to adjust the length of the lifting rod 121.

[0049] Combination Figure 5 As shown, in this embodiment, the mounting plate 221 is provided with a mounting base 510 by screws, the mounting base 510 is provided with a mounting post 511 in the middle, the mounting post 511 is provided with a threaded hole 512, and the bottom of the high-definition camera 100 is provided with a threaded post 521, which is threadedly connected to the threaded hole 512.

[0050] In this embodiment, the mounting base 510 is detachably mounted on the mounting plate 221 by screws. The high-definition camera 100 can be detachably mounted on the mounting base 510 by means of a threaded post 521 threaded into a threaded hole 512, thereby facilitating the assembly and disassembly of the high-definition camera 100 from the mounting assembly.

[0051] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
