Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation device technology, specifically to a ventilation device for a broadcast television transmitter room. Background Technology
[0002] In the field of broadcasting and television, transmitters are an indispensable piece of equipment. Transmitters generate a lot of heat during operation, and if this heat is not dissipated in a timely and effective manner, it will affect the normal use of the transmitter.
[0003] Currently, conventional transmitter rooms rely solely on doors, windows, or exhaust fans for ventilation, resulting in low efficiency. This prevents the timely and effective removal of heat, leading to localized overheating and affecting the transmitter's normal operation. Furthermore, the entry of humid air from outside can cause equipment inside the room to become damp and malfunction, further impacting the transmitter's functionality.
[0004] For example, the computer room exhaust device with Chinese patent application number CN2019223691534 has an air inlet pipe that is detachably connected to the inner top of the computer room, and the air inlet pipe is equipped with a fan, filter and air conditioner, which facilitates the conversion of air inside the computer room and facilitates the cooling of the computer room.
[0005] However, in this application, the outer end of the air inlet duct is open upwards, making it easy for external rainwater and humid air to enter the computer room, affecting the exhaust efficiency of the air inlet duct.
[0006] Design a ventilation device for broadcast television transmitter rooms to facilitate the timely removal of heat from the room while preventing humid air from entering and ensuring the efficient operation of the transmitter. Utility Model Content

The fixed base has a drying chamber inside, and a drying plate is slidably connected inside the drying chamber. The fixed plate is detachably connected to the outside of the exhaust pipe. An air outlet pipe is connected to the other side of the fixed base. A driving component is provided inside the fixed base, and the driving component is used to drive the drying plate to move.
[0009] As an optimization, the fixed base is provided with opposite exhaust openings on both sides. The area of the exhaust opening is larger than the opening area of the exhaust pipe. The end of the exhaust pipe adjacent to the fixed base gradually opens and is connected to the exhaust opening. The end of the exhaust pipe adjacent to the fixed base gradually opens and is connected to the other exhaust opening.
[0010] The mounting base is equipped with a detection module, which includes a temperature sensor, a humidity sensor, and a controller. The controller is connected to the temperature sensor and the humidity sensor via a circuit.
[0011] As an optimization, the length of the drying chamber is greater than twice the diameter of the exhaust opening. The middle part of the fixing seat protrudes outward to form a connecting shell. The connecting shell has a connecting cavity inside. The driving assembly includes a first driving motor and a driving roller. The interior of the connecting cavity is in communication with the interior of the drying chamber. The driving roller is rotatably connected to the interior of the connecting cavity. The first driving motor is fixed to the outside of the connecting shell. The output shaft of the first driving motor is fixedly connected to the axis of the driving roller.
[0012] As an optimization, the exhaust pipe is equipped with an exhaust fan inside, and the end of the exhaust pipe away from the fixed seat is provided with an external thread. The fixed plate is threadedly connected to the exhaust pipe, and a limiting plate is provided at the end of the threaded section of the exhaust pipe adjacent to the fixed seat. The limiting plate and the fixed plate are arranged opposite to each other, and both the limiting plate and the fixed plate are annular.
[0013] As an optimization, both the upper and lower parts of the fixing base are provided with drying openings, which are connected to the interior of the drying chamber, and a waterproof plate is slidably connected inside the drying opening.
[0014] As an optimization, the waterproof membrane is provided with connecting ears on the outside, and connecting screw holes are provided inside the connecting ears;
[0015] The fixed base is provided with a second drive motor on its exterior. The output shaft of the second drive motor is connected to a second drive screw, which is connected to a connecting screw hole.
[0016] As an optimization, the upper length of the air outlet duct is greater than the lower length of the air outlet duct.
[0017] The beneficial effects of this solution are as follows: A ventilation device for a broadcast television transmitter room has the following advantages:
[0018] The device is detachably connected to the transmitter room, facilitating efficient heat dissipation for the transmitter room. The mounting base is equipped with a drying plate, which efficiently dries and filters the air to prevent external humid air from entering the room and ensure the efficient operation of the transmitter.
[0019] The diameter of the connection between the exhaust duct, outlet duct and the fixed base is increased to improve the exhaust efficiency of the part where the air contacts the drying plate and prevent excessive local air pressure inside the exhaust duct.
[0020] The drying plate is moved by the first drive motor and drive roller, so that different parts of the drying plate work, thereby improving the drying effect on the air. Attached Figure Description

[0032] like Figure 1 , 2 As shown, a detection module is provided on the outside of the fixed base 2. The detection module includes a temperature sensor 7, a humidity sensor 8 and a controller. The controller is connected to the temperature sensor 7 and the humidity sensor 8 through a circuit.
[0033] like Figure 4 , 5 As shown, the length of the drying chamber 3 is greater than twice the diameter of the exhaust opening. The middle part of the fixing base 2 protrudes outward to form a connecting shell 9. The connecting shell 9 has a connecting cavity inside. The driving assembly includes a first driving motor and a driving roller 10. The interior of the connecting cavity is in communication with the interior of the drying chamber 3. The driving roller 10 is rotatably connected to the interior of the connecting cavity. The first driving motor is fixed to the outside of the connecting shell 9. The output shaft of the first driving motor is fixedly connected to the axis of the driving roller 10.
[0034] like Figure 5As shown, the exhaust pipe 1 is equipped with an exhaust fan 11 inside. The end of the exhaust pipe 1 away from the fixed seat 2 is provided with an external thread. The fixed plate 5 is threadedly connected to the exhaust pipe 1. The end of the threaded section of the exhaust pipe 1 adjacent to the fixed seat 2 is provided with a limiting plate 12. The limiting plate 12 is arranged opposite to the fixed plate 5. Both the limiting plate 12 and the fixed plate 5 are annular.
[0035] like Figure 5 As shown, both the upper and lower parts of the fixing base 2 are provided with drying openings, which are connected to the interior of the drying chamber 3. A waterproof plate 13 is slidably connected inside the drying opening.
[0036] like Figure 1 As shown, the waterproof membrane 13 has connecting ears on the outside and connecting screw holes inside the connecting ears;
[0037] like Figure 1 , 2 As shown, a second drive motor 14 is provided on the outside of the fixed base 2. The output shaft of the second drive motor 14 is connected to a second drive screw 15, and the second drive screw 15 is connected to the connecting screw hole.
[0038] like Figure 1 As shown, the upper length of the air outlet pipe 6 is greater than the lower length of the air outlet pipe 6.
[0039] This solution also includes a controller, the location of which is set by the operator according to the actual situation. The controller is used to control the electrical components used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, displays, computer input devices, switches, communication devices, lights, speakers, and microphones. The controller is an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller.

[0040] When the device is used, mounting holes are made in the transmitter room;
[0041] Unscrew the fixing plate 5, insert the exhaust pipe 1 into the mounting hole, and then rotate the fixing plate 5 to connect it to the exhaust pipe 1 to fix the exhaust pipe 1.
[0042] The exhaust fan 11 is controlled to run in the forward direction by the controller, and the exhaust fan 11 exhausts the overheated air inside the transmitter room to the outside.
[0043] When the exhaust fan 11 is not running, the exhaust fan 11 runs in reverse, and the outside air flows into the computer room through the air outlet duct 6 and the fixed base 2, so that the dry outside air enters the computer room and the air inside the computer room is ventilated.
[0044] External air is dried by drying plate 4 to prevent humid external air from entering the computer room.
[0045] After the drying plate 4 has been used for a period of time, the controller controls the drive roller 10 to operate. The drive roller 10 drives the drying plate 4 to move along the drying chamber 3, moving the used drying plate 4 away from the exhaust opening, so that the unused drying plate 4 reaches the exhaust opening and dries the incoming air efficiently.
[0046] When the humidity sensor 8 detects that the humidity of the outside air is low and the temperature sensor 7 detects that the outside temperature is high, the controller controls the second drive motor 14 to operate. The second drive motor 14 drives the waterproof plate 13 to move to one side through the second drive screw 15, so that the damp drying plate 4 is exposed to the air, which facilitates the natural air drying of the drying plate 4.
[0047] When the humidity sensor 8 detects that the external humidity is high, the controller controls the second drive motor 14 to operate, so that the waterproof plate 13 covers the drying chamber 3.
