Description

Technical Field

[0001] This utility model relates to the field of broadcast television transmitter room technology, and more specifically, to a ventilation device for broadcast television transmitter rooms. Background Technology

[0002] In many computer rooms, ventilation systems are crucial for ensuring the normal operation of equipment. Because the equipment generates a significant amount of heat during prolonged operation, it is essential to effectively remove this heat and introduce fresh outside air. Current technology involves adding ventilation structures to the computer room walls, which effectively exhausts heat from inside the room while simultaneously introducing fresh outside air. This incoming air undergoes preliminary filtration and purification, which not only effectively improves the air quality in the computer room but also prevents damage to the equipment from external contaminants and impurities.

[0003] However, existing technologies using filter plates for preliminary filtration of incoming air present several challenges in practical applications. First, the current filter plate designs are often inconvenient, leading to time-consuming and labor-intensive installation and disassembly, thus impacting operational efficiency. For scenarios requiring frequent maintenance and replacement, this inconvenient design not only increases workload but may also prolong equipment downtime. Second, cleaning the filter plates is also cumbersome. Traditional filter plate cleaning processes are complex and time-consuming, especially when using large areas of filter plates, making cleaning even more difficult and affecting the efficiency of subsequent maintenance.

[0029] Please see Figures 1-5 The ventilation system for a broadcast television transmitter room includes a mounting frame 1. A filter plate 2 is fixedly mounted on the outer side of the mounting frame 1 via a quick-installation mechanism. The quick-installation mechanism includes a rod 3, a fixing sleeve 4, an abutment plate 5, a hinge plate 6, a sliding groove 7, a sliding sleeve 8, and a limiting mechanism. The rod 3 is fixed to the outer wall of the mounting frame 1 and inserted into the filter plate 2. The fixing sleeve 4 abuts against the outer wall of the filter plate 2.

[0030] A positioning rod 14 is fixedly provided at the top of the insertion rod 3. A slot 15 is provided on the outer wall of the positioning rod 14. The cooperation between the slot 15 and the fixing sleeve 4 ensures a stable connection between the insertion rod 3 and the filter plate, preventing loosening or misalignment during use, and increasing the robustness and safety of the entire structure.

[0031] The fixing sleeve 4 has an insertion hole 16. Both the insertion hole 16 and the positioning hole are polygonal and are inserted together. The polygonal insertion design improves the insertion accuracy, making the insertion process tighter and more precise, reducing operational errors caused by loosening or misalignment, and ensuring the filter plate is fixed and stable.

[0032] Multiple sets of hinge plates 6 are rotatably connected at both ends to the bottom ends of multiple sets of abutment plates 5 and the inner side of the sliding sleeve 8. The rotatable connection of the hinge plates 6 provides flexibility for the filter plates during installation and disassembly, making the filter plates easy to disassemble and install, improving operating efficiency, and making them less prone to damage.

[0033] The bottom surface of the rotating sleeve 10 is provided with a reset mechanism, which includes a pressing block 17, a baffle 18 and a reset spring 19. Multiple sets of pressing blocks 17 are fixed to the bottom surface of the rotating sleeve 10, multiple sets of baffles 18 are fixed to the outer wall of the fixed sleeve 4, and multiple sets of reset springs 19 are provided and connected between multiple sets of pressing blocks 17 and baffles 18 respectively. The reset mechanism uses the elastic force provided by the reset springs 19 to ensure that the rotating sleeve 10 can automatically reset after disassembly, reducing the burden of manual operation and making the disassembly process smoother and more convenient.

[0034] Multiple sets of extrusion blocks 17 are each fixed with an arc-shaped rod 20 on their outer side, and multiple sets of baffles 18 are each provided with a sliding hole 21. The multiple sets of arc-shaped rods 20 slide in the multiple sets of sliding holes 21 respectively.

[0037] In this embodiment, during use, the mounting bracket 1 is installed inside the machine room wall, the filter plate 2 is installed outside the inlet fan 22, the filter plate 2 is inserted with multiple sets of insert rods 3, and then the fixing sleeve 4 is inserted with the positioning rod 14. The limiting sleeve 9 is pushed to drive the sliding sleeve 8 to slide along the sliding groove 7 and push the multiple sets of hinge plates 6. The multiple sets of hinge plates 6 push the abutment plate 5 to abut in the slot 15. The multiple top blocks 12 abut against the bottom of the limiting sleeve 9 to support and limit the sliding sleeve 8. The multiple sets of return springs 19 push the squeezing block 17 to limit the position of the rotating sleeve 10. The inlet fan 22 and the exhaust fan 23 are started. The inlet fan 22 introduces fresh air from outside into the machine room, and the exhaust fan 23 exhausts the heat inside the machine room to the outside.

[0038] More specifically, when the filter plate 2 needs to be disassembled, rotating the rotating sleeve 10 causes the pressing block 17 to push the arc rod 20 to slide along the sliding hole 21 and press the return spring 19. At the same time, it drives the multiple sets of top rods 11 and top blocks 12 to rotate. When the multiple sets of top blocks 12 rotate to below the relief groove 13, the multiple sets of top blocks 12 release the support of the limiting sleeve 9, push the limiting sleeve 9 to drive the sliding sleeve 8 to slide along the sliding groove 7, the sliding sleeve 8 pulls the hinge plate 6, the hinge plate 6 pulls the abutment plate 5 to disengage it from the slot 15, release the locking of the fixing sleeve 4 and the positioning rod 14, release the fixing of the fixing sleeve 4 on the filter plate 2, and then the filter plate 2 can be disassembled and cleaned.

[0039] In summary, the overall equipment is used or operated as follows: When in use, the mounting bracket 1 is installed inside the machine room wall, the filter plate 2 is installed outside the inlet fan 22, the filter plate 2 is inserted with multiple sets of insert rods 3, and then the fixing sleeve 4 is inserted with the positioning rod 14. The limiting sleeve 9 is pushed to drive the sliding sleeve 8 to slide along the sliding groove 7 and push the multiple sets of hinge plates 6. The multiple sets of hinge plates 6 push the abutting plate 5 to abut in the slot 15. The multiple top blocks 12 abut against the bottom of the limiting sleeve 9 to support and limit the sliding sleeve 8. The multiple sets of return springs 19 push the squeezing block 17 to limit the position of the rotating sleeve 10. The inlet fan 22 and the exhaust fan 23 are started. The inlet fan 22 introduces fresh air from outside into the machine room, and the exhaust fan 23 exhausts the heat inside the machine room to the outside. The filter plate 2 performs preliminary filtration and purification of the introduced air. When the inlet fan 22 and the exhaust fan 23 stop operating, the filter plate 2 is fixed outside the exhaust fan 23 to prevent unfiltered outside air from entering the machine room.

[0040] When the filter plate 2 needs to be disassembled, rotating the rotating sleeve 10 causes the pressing block 17 to push the arc rod 20 to slide along the sliding hole 21 and press the return spring 19. At the same time, it drives the multiple sets of top rods 11 and top blocks 12 to rotate. When the multiple sets of top blocks 12 rotate to the bottom of the relief groove 13, the support of the multiple sets of top blocks 12 on the limiting sleeve 9 is released. The limiting sleeve 9 is pushed to drive the sliding sleeve 8 to slide along the sliding groove 7. The sliding sleeve 8 pulls the hinge plate 6. The hinge plate 6 pulls the abutment plate 5 to disengage it from the slot 15. The locking of the fixing sleeve 4 and the positioning rod 14 is released, and the fixing sleeve 4 is released from the filter plate 2. Then the filter plate 2 can be disassembled and cleaned.
