Description

Technical Field

[0001] The utility model belongs to the technical field of demodulators, and in particular relates to an explosion-proof optical fiber modem for mining. Background Art

[0002] The purpose of a demodulator is to convert the information to be transmitted into a form that can be transmitted over a wireless channel. This means converting the signal to a frequency suitable for transmission. Generally speaking, modulation converts a baseband signal into a higher-frequency bandpass signal. Modulation is the process of using a baseband signal to alter parameters such as the amplitude, phase, or frequency of a high-frequency carrier according to specific rules.

[0003] Explosion-proof equipment for mines generally uses flameproof enclosures to protect the interior of electrical equipment, thereby ensuring that the electrical equipment can operate safely in explosive environments. Optical fibers are generally used inside mines to detect and transmit signals to the internal electrical equipment, so a demodulator is required to modulate and demodulate the light to facilitate signal transmission. However, the demodulator is generally fixed to its flameproof enclosure with multiple sets of bolts, which makes it inconvenient to disassemble the enclosure. When a fault occurs, it is inconvenient to maintain it, which is time-consuming and labor-intensive.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0038] See also Figures 1-6 As shown, the utility model is a mine explosion-proof optical fiber modem, comprising a housing 1:

[0039] The housing 1 is provided with a sealing assembly 2, a positioning assembly 3, a fixing assembly 4, a limiting assembly 5, and an installation assembly 6 respectively;

[0040] The sealing assembly 2 is provided at the top of the housing 1 so that the sealing assembly 2 seals the top of the housing 1;

[0041] The top end of the positioning assembly 3 is fixedly connected to the bottom end of the sealing assembly 2, so that the sealing assembly 2 cooperates with the positioning assembly 3 to be installed with the housing 1;

[0042] The outer surface of the fixing component 4 is rotatably arranged with the interior of the sealing component 2 so that the fixing component 4 can fix the sealing component 2 and the housing 1;

[0043] The outer surface of the limiting component 5 is slidably arranged inside the fixing component 4 so that the limiting component 5 limits the position of the fixing component 4;

[0044] One side of the installation component 6 is fixedly connected to one side of the housing 1 so that the installation component 6 can be installed in the position of the housing 1.

[0045] When in use, pick up the sealing component 2 and make it correspond to the top of the shell 1, and drive the positioning component 3 to correspond, so that it limits the position of the sealing component 2, and then push the sealing component 2 downward, so that the positioning component 3 is plugged in, and at the same time, it can drive the fixing component 4 set in its internal rotation to complete the socketing, and by pulling the limiting component 5, it can be moved out of the interior of the fixing component 4 during the movement, thereby releasing the position restriction of the fixing component 4, so that the fixing component 4 can be rotated. When the fixing component 4 is rotated 90 degrees, one end of the limiting component 5 can re-enter the interior of the fixing component 4, thereby limiting its rotation angle, that is, the fixing component 4 can fix the sealing component 2 and the shell 1. When the sealing component 2 needs to be disassembled, the position restriction of the fixing component 4 is released by pulling the limiting component 5, and then the fixing component 4 is rotated in the opposite direction and the sealing component 2 is pulled out, which is more convenient.

[0046] The utility model picks up the sealing component 2, makes it correspond to the top of the shell 1, and then pushes the sealing component 2 downward to drive the fixing component 4 to complete the socketing, and moves the limiting component 5 out of the interior of the fixing component 4 by pulling the limiting component 5, thereby releasing the position restriction of the fixing component 4, and then rotates the fixing component 4 90 degrees to make one end of the limiting component 5 enter the interior of the fixing component 4 again, thereby limiting its rotation angle, that is, the fixing component 4 can fix the sealing component 2 and the shell 1. When the sealing component 2 needs to be disassembled, the position restriction of the fixing component 4 is released by pulling the limiting component 5, and then the fixing component 4 is rotated in the opposite direction and the sealing component 2 is pulled out, thereby facilitating the disassembly of the sealing component 2. When the mining explosion-proof optical fiber modem fails, it is convenient to maintain it, which saves time and effort.

[0048] By inserting the sealing block 202 fixedly connected to the bottom end of the sealing plate 203 into the sealing groove 201, the interior of the shell 1 can be sealed, thereby preventing external dust and other impurities from entering the interior of the shell 1, thereby improving the sealing performance of the mining explosion-proof optical fiber modem.

[0050] The top end of the positioning rod 302 is fixedly connected to the bottom end of the sealing plate 203 , and the outer surface of the positioning rod 302 is slidably arranged inside the positioning hole 303 .

[0051] When the sealing plate 203 drives the sealing block 202 to be inserted into the sealing groove 201, it can drive the positioning rod 302 fixed at its bottom end to move, and insert one end of it into the positioning hole 303 opened at the top of the positioning block 301, so that the sliding direction of the sealing plate 203 can be limited during the downward sliding process, thereby improving the stability of the sealing plate 203 during the installation process.

[0052] In one embodiment, the fixing assembly 4 includes a fixing block 401 and a rotating shaft 402. One side of the fixing block 401 is fixedly connected to the inner wall of the housing 1. A slot 403 is provided inside the fixing block 401.

When the rotating shaft 402 moves, the connecting column 405 fixedly connected to its bottom end can be driven to move. When the connecting column 405 moves, the blocking block 406 fixedly connected to its outer surface can be driven to move. When the blocking block 406 moves, it can be inserted into the inside of the slot 403 opened at the top of the fixed block 401. Then, the knob 404 is rotated to drive the rotating shaft 402 fixedly connected to its bottom end to rotate. The rotating shaft 402 can cooperate with the connecting column 405 to drive the blocking block 406 to rotate. When the blocking block 406 rotates, its outer surface can be engaged with the inside of the slot 403, thereby completing the installation between the sealing plate 203 and the shell 1, which is more convenient.

[0055] In one embodiment, the above-mentioned limiting assembly 5 includes a mounting block 501 and a limiting groove 502. The bottom end of the mounting block 501 is fixedly connected to the top end of the sealing plate 203. The top end of the mounting block 501 is provided with a sliding groove 503.

Since the outer surface of the limit block 505 is set to slide inside the limit groove 502, and the limit groove 502 is provided with multiple groups and opened on the outer surface of the knob 404, when the limit block 505 moves, its outer surface can be separated from the inside of the limit groove 502, thereby facilitating the rotation of the knob 404. After the knob 404 is rotated to a certain angle, the position of the knob 404 can be limited by pushing the limit block 505 into the inside of another group of limit grooves 502, thereby facilitating the limitation of the rotation angle of the knob 404.

[0058] In one embodiment, for the above-mentioned limiting assembly 5, the limiting assembly 5 also includes a sliding rod 507 and a spring 508, one end of the sliding rod 507 is fixedly connected to the interior of the mounting block 501, the outer surface of the sliding rod 507 is slidingly arranged with the interior of the sliding block 506, one end of the spring 508 is fixedly connected to the interior of the mounting block 501, and the other end of the spring 508 is fixedly connected to one side of the sliding block 506.

The setting of the spring 508 makes it easier to continuously push the sliding block 506 to move, thereby allowing the sliding block 506 to push the limit block 505 into the limit groove 502, thereby improving the stability between the limit block 505 and the limit groove 502.
