Description

Technical Field

[0001] This utility model relates to the field of mine communication technology, and in particular to a wireless ground-penetrating communication device for use in mines. Background Technology

[0002] A mine shaft is a general term for the shafts, tunnels, equipment, surface buildings and structures that form an underground coal mine production system. Since mine shafts are all underground, communication is very troublesome. In order to ensure the normal operation of mine mining, a wireless communication device is needed to communicate with the surface. Therefore, a wireless ground-penetrating communication device for mines is particularly needed.

[0003] However, most existing wireless ground-penetrating communication devices used in mines are fixedly installed in the mine. The vibrations generated during the mining process will cause the communication devices to vibrate, which will affect the ground-penetrating transmission of signals and affect communication operations.

[0004] To address the aforementioned issues, a search revealed a patent (public account number 201921793341.3) that discloses an electronic information communication device for mine construction. The patent states that "due to the strong enclosure and high spatial interference of wireless communication in mines, the signal attenuation of gas acquisition data during wireless transmission is significant, resulting in a high error rate. This leads to data errors or omissions when the control center receives wireless signals, affecting the accurate judgment of ground rescue command." The device uses a gas analyzer to detect the concentration of hazardous gases underground in real time, sends the detection signal to a CPU for data processing, and designs a wireless communication unit to adjust the CPU's output signal. Finally, a wireless signal transmitter transmits the gas data signal to the surface control center without error, greatly enhancing the safety of mine construction and production. Furthermore, an amplification compensation circuit can utilize the RC feedback compensation principle to achieve fast and stable signal output. However, after installation, the communication device cannot avoid the impact of mine mining operations, and vibrations cannot prevent the signal transmission from being affected.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide a wireless ground-penetrating communication device for mines, in order to solve the problem mentioned in the background art that most existing wireless ground-penetrating communication devices for mines are fixedly installed in the mine. The vibration generated during the mining process will cause the communication device to vibrate, which will affect the ground-penetrating transmission of signals and affect the communication operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wireless ground-penetrating communication device for mines, comprising a communicator, an mounting plate fixedly mounted on the lower surface of the communicator, movable blocks fixedly mounted on both sides of the mounting plate, a mounting base connected to the outer wall of the movable blocks, sliding grooves formed on both sides of the inner wall of the mounting base, a support plate fixedly connected to the lower surface of the mounting plate, a lifting plate fixedly mounted on the lower surface of the support plate, sliders provided at both ends of the lifting plate, a screw rod penetrating one end of the support plate, a steel cover fixedly connected to the lower end of the screw rod, a first spring fixedly connected to the lower surface of the steel cover, a base fixedly connected to the other end of the first spring, a housing fixedly mounted on the upper surface of the base, a damping rubber pad adhered to the inner wall of the housing, and guide rails provided at both ends of the housing.

[0008] Preferably, the movable block forms a sliding structure with the mounting base through a groove, and the inner wall of the damping rubber pad is in contact with the outer wall of the lifting plate.

[0009] Preferably, the steel cover forms a telescopic structure with the base via a first spring.

[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: a wireless ground-penetrating communication device for mines, including a communicator 1. A mounting plate 2 is fixedly installed on the lower surface of the communicator 1. Movable blocks 3 are fixedly installed on both sides of the mounting plate 2. A mounting base 4 is connected to the outer wall of the movable blocks 3. Sliding grooves 5 are formed on both sides of the inner wall of the mounting base 4. A support plate 6 is fixedly connected to the lower surface of the mounting plate 2. A lifting plate 7 is fixedly installed on the lower surface of the support plate 6. Slider blocks 8 are provided at both ends of the lifting plate 7. A screw 9 is passed through one end of the support plate 6. A steel cover 10 is fixedly connected to the lower end of the screw 9. A first spring 11 is fixedly connected to the lower surface of the steel cover 10. A base 12 is fixedly connected to the other end of the first spring 11. A housing 13 is fixedly installed on the upper surface of the base 12. A damping rubber pad 14 is adhered to the inner wall of the housing 13. Guide rails 15 are provided at both ends of the housing 13. With the arrangement of communicator 1, mounting plate 2, moving block 3, mounting base 4, slide 5, support plate 6, lifting plate 7, slider 8, screw 9, steel cover 10, first spring 11, base 12, outer shell 13, damping rubber pad 14, and guide rail 15, when communicator 1 is installed in the mine, the vibration generated during mining causes communicator 1, along with mounting plate 2, to press down on support plate 6. Support plate 6, through screw 9, causes steel cover 10 to press down on first spring 11. When first spring 11 is under pressure, it generates an upward rebound force, which has a vibration reduction effect. When support plate 6 presses down, lifting plate 7 is moved along with it. At this time, lifting plate 7 rubs against damping rubber pad 14, which also has a vibration reduction effect. When lifting plate 7 moves up and down, slider 8 slides on guide rail 15. Slider 8 can limit the up and down movement of lifting plate 7 and the extension and retraction movement of first spring 11.

[0022] Furthermore, the movable block 3 forms a sliding structure with the mounting base 4 through the slide groove 5, and the inner wall of the damping rubber pad 14 contacts the outer wall of the lifting plate 7. Through the setting of the movable block 3 and the slide groove 5, the lifting movement of the mounting plate 2 can be limited when the movable block 3 slides in the slide groove 5.

[0023] Furthermore, the steel cover 10 forms a telescopic structure with the base 12 through the first spring 11. With the first spring 11, when the first spring 11 is subjected to downward pressure, it will generate an upward rebound force, which plays a role in vibration reduction.

[0024] Furthermore, the slider 8 forms a sliding structure with the outer shell 13 via the guide rail 15. With the slider 8 and the guide rail 15 in place, the slider 8 can limit the lifting movement of the lifting plate 7 when it slides on the guide rail 15.

[0025] Furthermore, a mounting block 16 is fixedly installed on one side surface of the communicator 1. Slots 17 are formed on both sides of the mounting block 16. A mounting bracket 18 is connected to one end of the mounting block 16. Storage slots 19 are formed on both sides of the inner wall of the mounting bracket 18. A second spring 20 is fixedly installed inside the storage slot 19. A locking block 21 is fixedly connected to the other end of the second spring 20. A connecting rod 22 is fixedly connected to one side surface of the locking block 21. Fixing plates 23 are fixedly installed on both sides of the mounting bracket 18. A bolt 24 is threaded through one end of the fixing plate 23. Through the arrangement of the mounting block 16, slots 17, mounting bracket 18, storage slots 19, second spring 20, locking block 21, connecting rod 22, fixing plate 23, and bolt 24, when installing the communicator 1... Use bolts 24 to fix the fixing plate 23 and the mounting bracket 18 in a suitable position in the mine. Then, align the mounting block 16 with the opening of the mounting bracket 18 and insert it. When the mounting block 16 is fully inserted into the mounting bracket 18, the locking block 21 is pushed into the slot 17 by the second spring 20. At this time, the mounting block 16 will be fixed inside the mounting bracket 18. Thus, the mounting block 16 is fixed in the mounting bracket 18. The mounting base 4 is fixed in the mine through the mounting bracket 18 and the fixing plate 23, and the installation of the communicator 1 is completed quickly. When disassembling, pull the connecting rod 22. The connecting rod 22 pulls the locking block 21 into the storage slot 19. At this time, the locking block 21 leaves the slot 17, allowing the mounting block 16 to leave the mounting bracket 18. The installation and disassembly of the communicator 1 are very convenient.

[0026] Furthermore, the card slot 17 and the card block 21 are sized to match. The card block 21 and the mounting block 16 form a locking structure through the card slot 17. With the setting of the card block 21, when the card block 21 enters the card slot 17, it can fix the mounting block 16, so that the mounting block 16 is fixed in the mounting bracket 18.

[0027] Furthermore, the locking block 21 forms a telescopic structure with the mounting bracket 18 via the second spring 20. With the setting of the second spring 20, when the connecting rod 22 is not under force, the elastic force of the second spring 20 will fix the locking block 21 in the locking groove 17, thereby limiting the mounting block 16.

[0028] Working principle: When installing the communicator 1, first use bolts 24 to fix the fixing plate 23 and the mounting bracket 18 in a suitable position in the mine. Then, align the mounting block 16 with the opening of the mounting bracket 18 and insert it. When the mounting block 16 is fully inserted into the mounting bracket 18, the locking block 21 is pushed into the slot 17 by the second spring 20. At this time, the mounting block 16 will be fixed inside the mounting bracket 18. Thus, the mounting base 4 is fixed in the mine through the mounting bracket 18 and the fixing plate 23, quickly completing the installation of the communicator 1. When disassembling, pull the connecting rod 22. The connecting rod 22 pulls the locking block 21 into the storage slot 19. At this time, the locking block 21... The mounting block 16 can be removed from the mounting frame 18 after leaving the slot 17. When the communicator 1 is installed in the mine, the vibration generated during the mining process causes the communicator 1 to press down the support plate 6 along with the mounting plate 2. The support plate 6 will press down the first spring 11 through the screw 9. When the first spring 11 is under pressure, it will generate an upward rebound force, which will have the effect of vibration reduction. When the support plate 6 is pressed down, the lifting plate 7 will be moved together. At this time, the lifting plate 7 rubs against the damping rubber pad 14, which will also have the effect of vibration reduction. When the lifting plate 7 moves up and down, the slider 8 will slide on the guide rail 15. The slider 8 can limit the up and down movement of the lifting plate 7 and the extension and retraction movement of the first spring 11.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
