Technical Field

[0001] This utility model relates to the technical field of coal bunker safety devices, specifically a safety device for coal bunkers in mines based on 3D model radar detection. Background Technology

[0002] The 3D model-based radar detection safety device for coal bunkers is a new technology that combines 3D modeling technology with radar detection systems. Through 3D modeling technology, it can accurately construct a three-dimensional structural model of the coal bunker, and then use radar detection technology to monitor the material accumulation inside the coal bunker in real time, which can effectively improve the safety management level of the coal bunker.

[0003] However, existing 3D model-based radar detection safety devices for coal bunkers in mines have the following problems when in use:

[0004] Because dust easily accumulates in coal bunkers, in order to reduce the impact of smoke and dust on the radar, a device is needed to store the radar when it is not in operation. However, existing safety devices for detecting coal bunkers in mines based on 3D models are not easy to store when the radar is not in operation, which can easily lead to dust accumulation on the radar and affect its operation.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing 3D model-based radar detection safety devices for coal bunkers in mines. Utility Model Content

[0006] The purpose of this invention is to provide a safety device for detecting coal bunkers in mines based on 3D model radar, in order to solve the problem mentioned in the background art that the existing safety devices for detecting coal bunkers in mines based on 3D model radar are not easy to store when the radar is not working, which easily leads to dust accumulation on the radar and affects its operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety device for detecting coal bunkers in mines based on D-model radar, comprising a support, a displacement motor, a servo motor, and a detection radar. A displacement motor is mounted on the back of one end of the support, and a secondary sprocket mechanism is provided on the inner wall of the other end of the support. A main sprocket is fixedly mounted on the outer wall of the displacement motor's output shaft. A positioning rod is fixedly connected to the lower inner wall of the support, and a suspension frame is fitted onto the outer wall of the positioning rod. A protective shell is fixedly connected to the lower surface of the suspension frame, and a servo motor is mounted on the inner wall of the protective shell's side. A lifting rod is fixedly connected to the upper end of the servo motor's output shaft, and a lifting sleeve is fitted onto the outer wall of the lifting rod. A lifting frame is fixedly connected to the side of the lifting sleeve, and a detection radar is mounted at the end of the lifting frame.

[0008] Preferably, the secondary sprocket mechanism includes a support rod and a secondary sprocket body, with the support rod rotatably mounted on the inner wall of the bracket and the secondary sprocket body fixedly disposed on the outer wall of the support rod.

[0009] Preferably, the outer wall of the secondary sprocket body is connected to the main sprocket via a chain, and the chain is fixedly connected to the suspension frame.

[0010] Preferably, the output shaft of the displacement motor and the bracket are rotatably connected, and the suspension frame and the positioning rod form a sliding structure.

[0011] Preferably, the lifting rod and the protective shell are rotatably arranged, the lifting rod and the lifting sleeve are threadedly connected, and the protective shell and the lifting frame are slidably arranged.

[0012] Preferably, the inner wall of the protective shell on the side of the detection radar is fixedly provided with bristles, and the detection radar and the bristles are fitted together.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the safety device for detecting coal bunkers in mines based on D-model radar is easy to store when the radar is not working, thereby avoiding the accumulation of dust on the radar and affecting its operation;

[0014] A servo motor drives a lifting rod, which in turn moves a lifting sleeve and a lifting frame upwards. The lifting frame then moves the detection radar upwards, causing the radar to retract into its protective housing. As the radar moves upwards, it presses the brush bristles against the radar surface, cleaning away surface dust. When the radar is fully retracted into the protective housing, it detaches from the brush bristles, allowing them to return to their original position. The protective housing and brush bristles protect the radar, making the device easy to store when the radar is not in operation, thus preventing dust accumulation from affecting its function.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a safety device for detecting coal bunkers in mines based on 3D model radar, including a support 1, a displacement motor 2, a secondary sprocket mechanism 3, a support rod 301, a secondary sprocket body 302, a main sprocket 4, a chain 5, a positioning rod 6, a suspension frame 7, a protective shell 8, a servo motor 9, a lifting rod 10, a lifting sleeve 11, a lifting frame 12, a detection radar 13, and brush bristles 14. The displacement motor 2 is installed on the back of one end of the support 1, and the secondary sprocket mechanism 3 is provided on the inner wall of the other end of the support 1. A main sprocket 4 is fixedly installed on the outer wall of the output shaft, and a positioning rod 6 is fixedly connected to the lower inner wall of the bracket 1. A suspension frame 7 is sleeved on the outer wall of the positioning rod 6. A protective shell 8 is fixedly connected to the lower surface of the suspension frame 7. A servo motor 9 is installed on the inner side of the protective shell 8. A lifting rod 10 is fixedly connected to the upper end of the output shaft of the servo motor 9. A lifting sleeve 11 is sleeved on the outer wall of the lifting rod 10. A lifting frame 12 is fixedly connected to the side of the lifting sleeve 11. A detection radar 13 is installed at the end of the lifting frame 12.

[0023] The secondary sprocket mechanism 3 includes a support rod 301 and a secondary sprocket body 302. The support rod 301 is rotatably mounted on the inner wall of the bracket 1, and the secondary sprocket body 302 is fixedly installed on the outer wall of the support rod 301. This facilitates the horizontal movement of the radar through the secondary sprocket mechanism 3, the main sprocket 4, and the chain 5, thereby fully detecting the coal bunker environment.

[0024] The outer wall of the secondary sprocket body 302 is connected to the main sprocket 4 via the chain 5, and the chain 5 is fixedly connected to the suspension frame 7, which facilitates the main sprocket 4 and the secondary sprocket body 302 to make the chain 5 move stably, thereby driving the suspension frame 7 to move horizontally.

[0025] The output shaft of the displacement motor 2 is rotatably connected to the bracket 1. The suspension frame 7 and the positioning rod 6 form a sliding structure, which facilitates the displacement motor 2 to drive the main sprocket 4 to rotate stably, so that the chain 5 drives the secondary sprocket body 302, thereby allowing the chain 5 to move stably and the suspension frame 7 to move stably relative to the positioning rod 6.

[0026] The lifting rod 10 and the protective shell 8 are rotatably configured, and the lifting rod 10 and the lifting sleeve 11 are threadedly connected. The protective shell 8 and the lifting frame 12 are slidably configured, which facilitates the servo motor 9 to drive the lifting rod 10 to rotate, so that the lifting sleeve 11 moves vertically upward, thereby driving the lifting frame 12 to slide upward relative to the protective shell 8, allowing the radar to retract into the protective shell 8.

[0027] The inner wall of the protective shell 8 on the side of the detection radar 13 is fixedly provided with bristles 14, and the detection radar 13 and the bristles 14 are fitted together, so that the detection radar 13 can move relative to the bristles 14 when it moves upward, thereby cleaning the floating dust on the surface of the detection radar 13 through the bristles 14, and protecting the detection radar 13 through the bristles 14 and the protective shell 8.

[0028] Working principle: When using this 3D model-based radar detection safety device for coal bunkers in mines, firstly as follows... Figures 1-5 As shown, the user fixes the bracket 1 to the top wall of the coal bunker. Then, the user connects the detection radar 13 to the computer system and uses the data collected by the radar 13 to create a 3D model of the coal bunker in the computer system. When it is necessary to adjust the position of the detection radar 13 to avoid blind spots, the user starts the displacement motor 2. The displacement motor 2 then drives the main sprocket 4 to rotate. Next, the main sprocket 4 drives the chain 5 to move. Simultaneously, the chain 5 drives the secondary sprocket body 302, causing the support rod 301 to rotate relative to the bracket 1. Then, the chain 5 drives the suspension frame 7 to slide relative to the positioning rod 6. At this time, the suspension frame 7 drives the protective shell 8 to move horizontally, thereby moving the position of the detection radar 13 to facilitate its thorough detection of the coal bunker environment. Then, when the detection radar 13 is not in use... The user starts the servo motor 9, which then drives the lifting rod 10 to rotate. Next, the lifting sleeve 11 moves vertically upward relative to the lifting rod 10. Subsequently, the lifting sleeve 11 drives the lifting frame 12 to move upward relative to the protective shell 8. Then, the lifting frame 12 drives the detection radar 13 to move upward, causing the detection radar 13 to retract into the protective shell 8. At the same time, as the detection radar 13 moves upward, the detection radar 13 presses the brush bristles 14 relative to the surface of the detection radar 13. At this time, the brush bristles 14 clean the surface dust of the detection radar 13. When the detection radar 13 is completely retracted into the protective shell 8, the detection radar 13 disengages from the brush bristles 14, causing the brush bristles 14 to reset. Thus, the detection radar 13 is protected by the protective shell 8 and the brush bristles 14. Therefore, the device is easy to store when the radar is not working, thereby preventing dust accumulation on the radar from affecting its operation.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
