[0002] In the unique and harsh working environment of underground coal mines, the real-time and accurate capture of key data such as gas concentration, roof pressure, underground temperature and humidity, and equipment operating parameters is crucial for ensuring production safety and improving mining efficiency. As the core hub for underground data aggregation and transmission, the coal mine underground data acquisition box must operate stably in extreme environments characterized by high humidity, high dust levels, strong vibrations, and severe electromagnetic interference.

[0003] Existing underground data acquisition boxes in coal mines typically consist of a protective shell, an interface module, a data acquisition module, and a processing and storage module. The protective shell is made of explosion-proof, dustproof, and impact-resistant materials, making it suitable for the extreme underground environment. The interface module is equipped with multiple types of ruggedized interfaces for connecting various sensors such as gas, pressure, temperature, and humidity sensors, as well as external devices. The data acquisition module receives analog and digital signals output by the sensors through the interface and converts them into processable electrical signals. The processing and storage module filters and calibrates the acquired signals before temporarily storing them in the local storage unit.

[0004] In existing technologies, some underground data acquisition boxes in coal mines often face the problem of unstable data transmission. This is because the data transmission line is prone to loosening during the acquisition process, which leads to data acquisition interruption. To address this issue, an underground data acquisition box for coal mines is proposed. Utility Model Content

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.

[0012] Example: A data acquisition box for underground coal mines, referring to Figures 1 to 3 The data acquisition box includes a housing 1, which is the basic structure of the entire data acquisition box. A partition 2 is fixedly connected inside the housing 1. The partition 2 is used to separate the electrical equipment related to data acquisition from the protective mechanism 4. An anti-detachment mechanism 3 is fixedly connected inside the housing 1. The protective mechanism 4 is fixedly connected inside the housing 1. The anti-detachment mechanism 3 includes a support plate 31, which serves as the main support component. The support plate 31 is externally fixedly connected to the inside of the housing 1. An annular support plate 32 is fixedly connected internally to the support plate 31, providing initial support and positioning for the data transmission line 38. An annular sliding plate 33 is slidably connected to the inner side of the support plate 31. When the data transmission line 38 is placed on the annular support plate 32, the annular sliding plate 33 can cooperate with the annular support plate 32 to clamp and fix the data transmission line 38. A sliding plate 34 is fixedly connected to the top of the annular sliding plate 33, facilitating the sliding of the annular sliding plate 33. The outer side of the plate 34 is slidably connected to the inside of the support plate 31. The top of the annular support plate 32 is fixedly connected to an anti-slip pad 35, which increases the friction between the data transmission line 38 and the annular support plate 32. The inner side of the support plate 31 is fixedly connected to an elastic component 36. The outer side of the partition plate 2 is fixedly connected to a data collector 37. The data collector 37 has a chip inside for receiving and storing data from the data transmission line 38. The data transmission line 38 is fixedly connected inside the data collector 37 and plays the role of transmitting data. The outer side of the data transmission line 38 is in contact with the top of the anti-slip pad 35 and the bottom of the annular slide plate 33. The elastic component 36 includes a round rod 361, which provides a guide track for the sliding of the annular slide plate 33. The outer side of the round rod 361 is fixedly connected to the inner side of the support plate 31, and the inner side of the annular slide plate 33 is slidably connected to the outer side of the round rod 361. A spring 362 is sleeved on the outer side of the round rod 361. The spring 362 generates a downward elastic force on the annular slide plate 33, so that the annular slide plate 33 can be pressed tightly onto the data transmission line 38, thereby achieving a firm clamping of the data transmission line 38. The top of the spring 362 is fixedly connected to the inner side of the support plate 31, and the bottom of the spring 362 is fixedly connected to the top of the annular slide plate 33. Specifically, when it is necessary to fix the data transmission line 38, the data transmission line 38 is first placed on the anti-slip pad 35 on the top of the annular support plate 32. The spring 362 drives the annular slide plate 33 to slide down along the round rod 361 through its own elasticity. When the annular slide plate 33 moves to the bottom and makes close contact with the data transmission line 38, the data transmission line 38 is firmly clamped between the annular support plate 32 and the annular slide plate 33. The data transmission line 38 transmits the data collected in the coal mine to the data collector 37, and the data collector 37 receives and stores the data.

[0013] Reference Figure 2 and Figure 5 The protective mechanism 4 includes a connecting box 41, which provides an installation position for the nozzles 42. The outside of the connecting box 41 is fixedly connected to the inside of the partition 2. Multiple nozzles 42 are fixedly connected to the bottom inside the connecting box 41. The nozzles 42 can evenly spray the carbon dioxide released from the carbon dioxide storage tank 43 into the inside of the box 1 to extinguish the fire and ensure the safety of the data. The inside of the box 1 is fixedly connected to the carbon dioxide storage tank 43, which stores carbon dioxide gas. The top of the carbon dioxide storage tank 43 is fixedly connected to the control valve 44, which is used to control the opening and closing of the carbon dioxide storage tank 43. The output end of the control valve 44 is fixedly connected to the delivery pipe 45, which delivers carbon dioxide gas. The outside of the delivery pipe 45 is fixedly connected to the inside of the connecting box 41. The inside of the partition 2 is fixedly connected to the smoke detector assembly 46. The smoke detection assembly 46 includes a smoke detector 461, which is used to monitor the smoke concentration inside the housing 1 in real time. The smoke detector 461 is externally fixedly connected to the inside of the partition 2. A signal line 462 is externally fixedly connected to the smoke detector 461. The signal line 462 is used to transmit signals. The signal line 462 is externally fixedly connected to the inside of the control valve 44. Specifically, the smoke detector 461 monitors the smoke concentration inside the enclosure 1 in real time. When the smoke concentration reaches the preset alarm threshold, the smoke detector 461 sends a signal to the control valve 44 through the signal line 462. After receiving the signal, the control valve 44 opens, and the carbon dioxide gas in the carbon dioxide storage tank 43 is transported to the connecting box 41 through the delivery pipe 45. Then, it is evenly sprayed into the interior of the enclosure 1 through multiple nozzles 42 on the bottom side of the connecting box 41.

[0014] Reference Figure 1 , Figure 2 and Figure 4An L-shaped connecting plate 5 is fixedly connected to the outside of the box body 1. The L-shaped connecting plate 5 provides a connection and support structure for the rotation of the box door 6. The box door 6 is rotatably connected inside the L-shaped connecting plate 5. The box door 6 is used to close the box body 1. A sealing ring 7 is fixedly connected to the outside of the box body 1. When the box door 6 is closed, the sealing ring 7 can fill the gap between the box door 6 and the box body 1, thus providing a sealing function. The outside of the sealing ring 7 is in contact with the outside of the box door 6. A connecting block 8 is fixedly connected to the outside of the box body 1. After the box door 6 is closed, the L-shaped plate 9 cooperates with the connecting block 8 to provide a certain degree of limitation and fixation for the box door 6. The function is as follows: an L-shaped plate 9 is fixedly connected to the outside of the box door 6. The L-shaped plate 9 cooperates with the connecting block 8 to help fix the box door 6 and enhance the stability of the box door 6 after it is closed. The inner side of the L-shaped plate 9 is slidably connected to the outside of the connecting block 8. A hanging plate 10 is fixedly connected to one side of the box body 1. The hanging plate 10 is used to hang the box body 1 on the support frame. A U-shaped plate 11 is fixedly connected to one side of the box body 1. The U-shaped plate 11 provides an installation base for the arc-shaped mounting bracket 12. The arc-shaped mounting bracket 12 is rotatably connected inside the U-shaped plate 11. The arc-shaped mounting bracket 12 is used to install the box body 1 on a columnar object. Specifically, when hanging the box 1 on the support frame, the hanging plate 10 can be used to suspend the box 1 at a suitable position on the support frame. When installing the box 1 on a columnar object, first adjust the angle of the arc-shaped mounting bracket 12 so that the arc-shaped mounting bracket 12 fits against the columnar object, and then use the arc-shaped mounting bracket 12 to fix the box 1 on the columnar object. When it is necessary to open the box 1, the L-shaped plate 9 on the outside of the sliding door 6 separates from the connecting block 8, and then the door 6 is rotated around the L-shaped connecting plate 5 on the outside of the box 1 to open the box 1. When closing the door 6, the door 6 is rotated in the opposite direction so that the door 6 contacts the sealing ring 7 on the outside of the box 1. The door 6 drives the L-shaped plate 9 to cooperate with the connecting block 8 to complete the closing and fixing of the door 6.

[0015] The implementation principle of this application embodiment is as follows: During installation, the box 1 can be hung on the support frame using the hanging plate 10, or the arc mounting bracket 12 inside the U-shaped plate 11 can be adjusted to fit the columnar object, and the box 1 can be installed on the columnar object. When fixing the data transmission line 38, the sliding plate 34 first drives the annular sliding plate 33 to move upward. The annular sliding plate 33 can slide outside the round rod 361, while the spring 362 is compressed. Then, the data transmission line 38 is placed on the anti-slip pad 35 on the top of the annular support plate 32. The sliding plate 34 is released, and the spring 362 restores its deformation and generates elastic force. The elastic force drives the annular sliding plate 33 to slide down the round rod 361 until the bottom of the annular sliding plate 33 is in close contact with the data transmission line 38, clamping the data transmission line 38 between the annular support plate 32 and the annular sliding plate 33 to prevent the data transmission line 38 from loosening. The data transmission line 38 transmits the data collected downhole to the data collector 37, and the data collector 37 receives and stores the data. The smoke detector 461 monitors the smoke concentration inside the enclosure 1 in real time. When the concentration reaches the alarm threshold, the smoke detector 461 sends a signal to the control valve 44 through the signal line 462. The control valve 44 opens, and the carbon dioxide in the carbon dioxide storage tank 43 is delivered to the connecting box 41 through the delivery pipe 45. Then, multiple nozzles 42 on the bottom side of the connecting box 41 spray the carbon dioxide evenly into the enclosure 1. When the enclosure 1 needs to be opened, the door 6 is rotated to separate the L-shaped plate 9 from the connecting block 8, which opens the door 6. When closing, the door 6 is rotated in the opposite direction to make the door 6 contact the sealing ring 7. The door 6 drives the L-shaped plate 9 to cooperate with the connecting block 8. The door 6 can be locked in place by using a lock.
