Description

Technical Field

[0001] This utility model relates to the field of underground power monitoring technology in coal mines, specifically a transmission device for a coal mine power monitoring system. Background Technology

[0002] The transmission equipment of the coal mine power monitoring system is used to realize the transmission of data and signals in the coal mine power monitoring system, ensuring information exchange between the monitoring center and various power equipment, so as to realize real-time monitoring and control of the coal mine power system.

[0003] Transmission equipment generates heat during operation. Existing transmission equipment mostly relies on ventilation holes on the external enclosure for heat dissipation. After long-term use, the ventilation holes are easily clogged with dust, which affects normal heat dissipation. This requires staff to disassemble the enclosure for cleaning, which is a cumbersome operation and the cleaning effect is poor. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a transmission device for a coal mine power monitoring system. It has the advantage of easy cleaning of the heat dissipation mesh, solving the problem that existing transmission devices mostly rely on external heat dissipation holes for heat dissipation, which are prone to clogging after long-term use, making it inconvenient for staff to clean and thus affecting the heat dissipation effect.

[0008] The equipment box has symmetrically arranged heat dissipation vents on its outer side wall;

[0009] A heat dissipation mesh is disposed inside the heat dissipation vent;

[0010] The main component is provided with a replacement component, which includes:

[0011] Connecting blocks are symmetrically and fixedly connected to the outer wall of the heat dissipation mesh;

[0012] A limiting groove is formed on the connecting block;

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, this utility model provides a transmission device for a coal mine power monitoring system, which has the following beneficial effects:

[0025] This transmission device features easy cleaning of the heat dissipation mesh. When dust clogs the mesh, pulling the rods to both sides causes the limiting blocks to disengage from the limiting grooves and retract into the cavity. Pulling them outwards allows for the removal of the heat dissipation mesh, facilitating cleaning. After cleaning, pulling the rods to both sides again causes the limiting blocks to retract into the cavity and compress the spring. The heat dissipation mesh can then be inserted into the heat dissipation vent, and releasing the rods causes the spring to spring the limiting blocks back into the limiting grooves, thus limiting the connection block and installing the heat dissipation mesh. This facilitates heat dissipation and filtration during equipment use. It solves the problem that existing transmission devices often rely on external ventilation holes for heat dissipation, which easily become clogged after prolonged use, making cleaning difficult and affecting heat dissipation efficiency.

[0034] 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.

[0035] Example 1

[0036] See Figure 1-4 A power monitoring system transmission device for a coal mine includes a main component 1, which includes: an equipment box 11 with symmetrically arranged heat dissipation vents 12 on its outer side wall; a heat dissipation mesh 13 disposed within the heat dissipation vents 12; and a replacement component 2 disposed on the main component 1. The replacement component 2 includes: a connecting block 21 symmetrically and fixedly connected to the outer side wall of the heat dissipation mesh 13; a limiting groove 22 disposed on the connecting block 21; a cavity 23 symmetrically disposed at the top and bottom of the heat dissipation vents 12; a placement groove 24 symmetrically disposed at the top and bottom of the heat dissipation vents 12, wherein the cavity 23 and the placement groove 24 are interconnected; a spring 25, one end of which is fixedly connected to the inner side wall of the cavity 23; a limiting block 26 fixedly connected to the other end of the spring 25; and a rod 27, one end of which is fixedly connected to the side wall of the limiting block 26 near the heat dissipation mesh 13, and the other end extending through and to the outside of the equipment box 11, wherein the equipment box 11 has a through groove for the rod 27 to move. A baffle 3 is fixedly connected to the inner side wall of the heat dissipation vent 12. A bracket 41 is fixedly connected to the bottom surface inside the equipment box 11, and a fan 4 is provided on the top of the bracket 41.

[0037] When dust clogs the heat dissipation mesh 13, the operator pulls the rod 27 to both sides simultaneously, causing the rod 27 to separate the limiting block 26. At this time, the limiting block 26 disengages from the limiting groove 22 and retracts into the cavity 23. The connecting block 21 is no longer restricted and can be pulled out to disassemble the heat dissipation mesh 13, making it easier for the operator to clean the heat dissipation mesh 13 separately, resulting in better cleaning. After cleaning, the operator pulls the rod 27 to both sides again, causing the limiting block 26 to retract into the cavity 23 and compress the spring 25. At this time, the heat dissipation mesh 13 is inserted into the heat dissipation port 12, and the rod 27 is released. The spring 25 pushes the limiting block 26 into the limiting groove 22, thereby limiting the connecting block 21 and installing the heat dissipation mesh 13, which facilitates heat dissipation and filtration during the use of the equipment box 11.

[0038] When the heat dissipation mesh 13 is installed inside the heat dissipation port 12, the baffle 3 fits against the heat dissipation mesh 13 and blocks and limits the heat dissipation mesh 13. At this time, the positions of the limiting groove 22 and the limiting block 26 correspond to each other, which facilitates the installation of the heat dissipation mesh 13.

[0039] When the equipment enclosure 11 is in use, the ventilation and heat dissipation effect of the heat dissipation mesh 13 alone is poor. At this time, the fan 4 is turned on. The fan 4 blows the heat flow inside the equipment enclosure 11 through the heat dissipation mesh 13 to the outside of the equipment enclosure 11, increasing the speed of air circulation inside and outside the equipment enclosure 11, thereby enhancing the heat dissipation effect. At the same time, the airflow generated by the fan 4 can exert force on some loose dust attached to the heat dissipation mesh 13, causing this dust to be removed from the surface of the heat dissipation mesh 13 under the impact of the airflow, thereby playing a certain cleaning role, reducing the accumulation of dust on the heat dissipation mesh 13, and thus reducing the frequency of cleaning of the heat dissipation mesh 13 by the staff.

[0040] The aforementioned equipment box 11 houses a microprocessor, communication interface chip, power management chip, memory chip, and crystal oscillator, among other components. Its workflow is as follows: Equipment box 11 acquires various parameters from the coal mine power system, such as voltage, current, power, and switch status, through sensors or other data acquisition devices. These data are typically in the form of analog or digital signals. The microprocessor analyzes, processes, and packages the digital signals, encapsulating the data into frame formats according to a specific communication protocol, adding address, checksum, and other information to form data frames that can be transmitted over a communication network. The communication interface chip, according to the set communication protocol, converts the data frames processed by the microprocessor into a signal format suitable for transmission over a specific communication medium. The receiving end's transmission equipment receives the signals through the corresponding communication interface chip, converts them into digital signals, and transmits them to the microprocessor. The microprocessor unpacks the received data frames according to the communication protocol, extracts the valid data, performs verification and error detection, ensuring data integrity and accuracy. The processed and verified data can be output in various ways, such as being sent to a computer in the monitoring center for display and analysis, or transmitted to other control equipment for remote control and regulation of the coal mine power system. The specific installation structure will not be detailed here.

[0041] Example 2

[0042] An auxiliary function has been added based on Embodiment 1.

[0043] See Figure 1-4 The limiting block 26 has an inclined surface on the side near the heat dissipation mesh 13. A temperature sensor 5 is provided on the inner wall of the equipment box 11, and a controller 51 is also provided on the inner wall of the equipment box 11. The temperature sensor 5 is electrically connected to the fan 4 through the controller 51. A handle 6 is symmetrically and fixedly connected to the side of the heat dissipation mesh 13 away from the heat dissipation port 12.

[0044] The inclined surface on the limiting block 26 allows the operator to fix the heat dissipation mesh 13 without pulling the rod 27 in advance: the operator directly inserts the cleaned heat dissipation mesh 13 into the heat dissipation port 12. At this time, the connecting blocks 21 enter the placement groove 24 in sequence. When the edge of the connecting block 21 contacts the inclined surface of the limiting block 26, it pushes the limiting block 26 into the cavity 23. The spring 25 is compressed. When the connecting block 21 is in contact with the inner side of the placement groove 24, the limiting block 26 and the limiting groove 22 are on the same longitudinal axis. At this time, the spring 25 automatically springs the limiting block 26 into the limiting groove 22, thereby achieving the limiting and fixing of the connecting block 21 and improving the convenience of installing the heat dissipation mesh 13. When the equipment box 11 is in operation, the temperature sensor 5 inside the equipment box 11 monitors the temperature inside the equipment box 11. When the temperature exceeds the threshold, the temperature sensor 5 transmits the temperature data to the controller 51. The controller 51 outputs a start signal to the fan 4, and the fan 4 automatically dissipates heat to avoid the equipment box 11 overheating and causing safety hazards. The handle 6 on the outside of the heat dissipation mesh 13 increases the convenience and stability for staff when disassembling the heat dissipation mesh 13.

[0045] The temperature sensor 5 described above utilizes the property that the resistance of metal or semiconductor materials changes with temperature to measure the temperature inside the equipment enclosure 11. The resistance of most metals increases with temperature; for example, platinum resistance thermometers have a relatively precise mathematical relationship between their resistance and temperature. By measuring the resistance of the resistance thermometer, the corresponding temperature can be calculated.

[0046] 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.
