Description

Technical Field

[0001] This utility model relates to the field of underground mining communication technology, and more specifically, to an underground mining communication device. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. Coal mines typically include roadways, shafts, and working faces. When workers are working underground, they usually need to use communication devices. However, existing technologies have the following shortcomings in their use:

[0003] The underground mining area is connected to the upper and lower sections, and pedestrian traffic frequently occurs in these sections. There are multiple electric scrapers in the mining area. When workers enter the mining area, these electric scrapers may still be working continuously, and the audible and visual alarms may not be activated, which could lead to accidental injury to personnel. At the same time, the communication devices used by workers are often equipped with charging interfaces, but the underground mining area often contains a lot of dust and powder. If the charging interfaces are exposed to the outside for a long time, it may affect the subsequent use of the charging interfaces.

[0004] Therefore, there is an urgent need for an underground mining communication device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the current situation where underground mining areas are connected to upper and lower sections, and pedestrian traffic frequently occurs between these sections. Multiple electric scrapers exist within the mining area, and when workers enter, these scrapers may continue operating without providing audible and visual alarms, potentially causing injury. Furthermore, the communication devices used by workers often have charging interfaces, but underground mining areas often contain large amounts of dust and powder, and prolonged exposure of these charging interfaces may affect their effectiveness.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A communication device for underground mining operations is proposed to improve the aforementioned problems.

[0008] The application is as follows:

[0009] A communication device for underground mining operations includes a control switch, a battery, an audible and visual alarm, and a communication unit. The communication unit has a charging port at its bottom, a connecting block below it, a sealing gasket fixedly connected to the top of the connecting block, two first positioning rings fixedly connected to the bottom of the communication unit, two positioning blocks fixedly connected to the top of the connecting block, a slider directly below the connecting block, a spring fixedly connected between the connecting block and the slider, a fixing block fixedly connected to the bottom of the communication unit on one side of the first positioning rings, two connecting rods fixedly connected to the right side wall of the fixing block, the slider slidingly mounted on the two connecting rods, and two second positioning rings fixedly connected to the bottom of the communication unit.

[0010] As a preferred technical solution of this application, the power supply input terminal of the control switch is electrically connected to the power supply output terminal of the storage battery, and the power supply output terminal of the control switch is electrically connected to the power supply input terminal of the audible and visual alarm.

[0011] As a preferred technical solution of this application, two symmetrically distributed telescopic guide rods are fixedly connected between the connecting block and the slider, and the spring is located between the two telescopic guide rods.

[0012] As a preferred technical solution of this application, an elastic clip is fixedly connected to the back of the communication device body.

[0013] As a preferred technical solution of this application, the sealing gasket is attached to the bottom of the communication device body, and the sealing gasket is located outside the charging interface.

[0014] As a preferred technical solution of this application, the positioning block is adapted to the first positioning ring, and the two positioning blocks are respectively inserted into the two first positioning rings.

[0015] As a preferred technical solution of this application, the two second positioning rings are parallel to the two first positioning rings, and the specifications of the second positioning rings are the same as those of the first positioning rings.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. Before entering the mining area, press the control button on the control switch to activate the audible and visual alarm installed near the electric scraper. This will alert the electric scraper operator that someone is about to enter the mining area. At this time, the electric scraper operator can immediately stop operating the scraper to ensure the safety of the personnel about to enter the mining area.

[0019] 2. By using a combination of connecting block, sealing gasket, first positioning ring, positioning block, slider, spring and connecting rod, dust can be prevented from entering the charging interface when the communication device is used in the mining area, greatly improving the dustproof performance of the charging interface and ensuring the subsequent use effect of the charging interface.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Example

[0031] like Figure 1-4As shown in this embodiment, a communication device for underground mining operations includes a control switch 1, a battery 2, an audible and visual alarm 3, and a communication unit 4. Before a worker enters the mining area, pressing the control button on the control switch 1 activates the audible and visual alarm 3, which is installed near the electric scraper, to alert the scraper operator that someone is about to enter. The communication unit 4 has a charging port 5 at its bottom. At this time, the scraper operator can immediately stop operating the scraper, ensuring the safety of the worker entering the mining area. A connecting block 6 is located below the communication unit 4, with a sealing gasket 7 fixedly connected to the top of the connecting block 6. Two first positioning rings 8 are fixedly connected to the bottom of the communication unit 4, and two positioning blocks 9 are fixedly connected to the top of the connecting block 6. A slider 10 is located directly below the connecting block 6, and a spring 11 is fixedly connected between the connecting block 6 and the slider 10. When the communication unit 4 is used in the mining area, the spring 11 keeps the sealing gasket 7 constantly sealing the charging port 5, preventing the inside of the charging port 5 from entering. Dust is greatly reduced, improving the dustproof performance of the charging interface 5 and ensuring its effectiveness in subsequent use. A fixed block 12 is fixedly connected to the bottom of the communicator body 4, located on one side of the first positioning ring 8. When the operator pulls the connecting block 6 downwards, the two positioning blocks 9 disengage from the two first positioning rings 8, causing the spring 11 to compress and deform. Then, the connecting block 6 is pulled closer to the fixed block 12. Two connecting rods 13 are fixedly connected to the right side wall of the fixed block 12. The slider 10 slides on the two connecting rods 13, guiding it. Two second positioning rings 14 are fixedly connected to the bottom of the communicator body 4. When the slider 10 is in contact with one end face of the fixed block 12, the connecting block 6 is released, and the elastic force of the spring 11 causes the connecting block 6 to move upwards, allowing the two positioning blocks 9 to be inserted into the two second positioning rings 14, thus positioning the connecting block 6. At this point, the charging interface 5 is fully exposed, facilitating subsequent charging of the communicator body 4.

[0032] Meanwhile, the number of audible and visual alarms 3 can be determined according to the actual situation of the mining site.

[0033] like Figure 1 As shown, the power input terminal of control switch 1 is electrically connected to the power output terminal of battery 2, and the power output terminal of control switch 1 is electrically connected to the power input terminal of audible and visual alarm 3. Before a worker enters the mining area, pressing the control button on control switch 1 will trigger the audible and visual alarm 3 installed near the electric rake to sound an alarm, thereby reminding the electric rake operator in the mining area that someone is about to enter the mining area.

[0034] like Figure 2As shown, two symmetrically distributed telescopic guide rods 15 are fixedly connected between the connecting block 6 and the slider 10. The spring 11 is located between the two telescopic guide rods 15. When the connecting block 6 is pulled, the two telescopic guide rods 15 guide the connecting block 6, so that the connecting block 6 moves vertically.

[0035] like Figure 3 As shown, the back of the communicator body 4 is fixedly connected to an elastic clip 16. With the elastic clip 16, the communicator body 4 can be easily clipped to the edge of a pocket, eliminating the need to hold it in your hand all the time, thus freeing up your hands and making your work more convenient and efficient.

[0036] like Figure 1 and Figure 2 As shown, the sealing gasket 7 is attached to the bottom of the communication device body 4, and the sealing gasket 7 is located outside the charging interface 5. The sealing gasket 7 can be made of silicone rubber, which has good weather resistance, is not easy to age, and has a long service life.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the positioning block 9 is adapted to the first positioning ring 8, and the two positioning blocks 9 are respectively inserted into the two first positioning rings 8. The two positioning blocks 9 cooperate with the two first positioning rings 8 to position the connecting block 6 and the sealing gasket 7. The sealing gasket 7 seals the charging interface 5 to prevent dust from entering the charging interface 5.

[0038] like Figure 4 As shown, the two second positioning rings 14 are parallel to the two first positioning rings 8, and the second positioning rings 14 have the same specifications as the first positioning rings 8.

[0039] Specifically, when using the underground mining communication device: The control switch 1 is installed in a conspicuous and easily accessible location at the mining entrance. It is a waterproof, dustproof, and durable explosion-proof push-button switch. Simultaneously, the audible and visual alarm 3 can be installed near the electric scraper. The battery 2 is also a mining explosion-proof battery. Before a worker enters the mining area, pressing the control button on the control switch 1 will activate the audible and visual alarm 3 near the electric scraper, alerting the scraper operator that someone is about to enter. The scraper operator can then immediately stop operating the scraper, ensuring the safety of the worker entering the mining area. When the communication device 4 is used inside the mining area, the spring 11 keeps the sealing gasket 7 constantly blocking the charging interface 5, preventing dust from entering and significantly improving efficiency. The dustproof performance of the charging interface 5 ensures the effectiveness of its subsequent use. When the communication device body 4 needs to be charged, the operator pulls the connecting block 6 downwards, causing the two positioning blocks 9 to disengage from the two first positioning rings 8 respectively. The spring 11 is compressed and deformed under force. Then, the connecting block 6 is pulled towards the fixed block 12, and the slider 10 slides on the two connecting rods 13. The two connecting rods 13 guide the slider 10. When the slider 10 is in contact with one end face of the fixed block 12, the connecting block 6 is released. The elastic force of the spring 11 drives the connecting block 6 upwards, so that the two positioning blocks 9 are inserted into the two second positioning rings 14 respectively, thereby positioning the connecting block 6. At this time, the charging interface 5 is fully exposed, which facilitates the subsequent charging of the communication device body 4. The model of the communication device body 4 in this application is: KTL121.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
