Description

Technical Field

[0001] The utility model relates to the technical field of cabinets, in particular to a cabinet for a radio and television transmitter. Background Art

[0002] A television transmitter is a radio device that modulates the image video signal and accompanying audio signal that conform to a certain television broadcasting standard at a fixed intermediate frequency, then frequency converts it to a specified radio frequency, amplifies it to a specified power level, and finally feeds it to a specified load antenna to make the signal waveform conform to the radio frequency characteristics of the television broadcasting standard. In order to ensure the stability of the broadcast signal, the requirements for radio and television transmitters are extremely strict, so radio and television transmitters are usually installed in professional cabinets for protection.

[0006] A cabinet for a radio and television transmitter comprises a cabinet body, air inlets are provided on both sides of the cabinet body, a plurality of baffles are arranged at equal intervals from top to bottom in the air inlet, a damping shaft is installed in the middle of the baffles, the baffles are connected to the cabinet plates on both sides of the air inlet for damping rotation through the damping shaft, a filter screen plate is installed horizontally on one side of the air inlet, an exhaust pipe is installed on the upper part of the cabinet body, an upper cover is installed on the exhaust pipe, a filter screen cover is installed on the bottom surface of the upper cover, a cooling fan is installed on the top of the cabinet body, the filter screen cover covers the cooling fan, and air outlets are provided on four sides of the exhaust pipe at equal intervals.

[0007] As a further solution of the utility model: horizontal mounting frames are installed on the inner walls on both sides of the cabinet, vertical mounting frames are installed on the horizontal mounting frames by bolts, and mounting holes are opened on the vertical mounting frames at equal intervals from top to bottom.

[0008] As a further solution of the utility model: the upper cover is plugged and fixed to the upper pipe opening of the exhaust pipe.

[0009] As a further solution of the present invention: the bottom end of the filter screen is in contact with the top surface of the cabinet.

[0010] As a further solution of the utility model: a handle is installed at one end of the filter plate outside the air inlet.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model sets an air inlet and installs a baffle on the air inlet. Both ends of the baffle are connected to the air inlet damping rotation. The personnel can rotate and adjust the baffle according to the heat dissipation of the equipment in the cabinet of the radio and television transmitter, thereby changing the effective ventilation area between the upper and lower adjacent baffles, so as to better meet the ventilation and heat dissipation needs in emergency situations.

[0013] 2. The utility model provides a filter screen plate and a filter screen cover, which can filter dust from the air entering from both sides and the top of the cabinet to keep the cabinet clean. The filter screen plate can be pulled out from one side of the air inlet, and the filter screen cover is installed at the bottom of the upper cover and can be removed from the cabinet along with the upper cover, so that the filter screen plate and the filter screen cover can be easily disassembled and cleaned, making the maintenance of the radio and television transmitter cabinet more convenient.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 4 In an embodiment of the utility model, a cabinet for a radio and television transmitter includes a cabinet body 1, air inlets 2 are opened on both sides of the cabinet body 1, a plurality of baffles 3 are arranged at equal intervals from top to bottom in the air inlet 2, a damping shaft 13 is installed in the middle of the baffle 3, the baffle 3 is connected to the cabinet plates on both sides of the air inlet 2 through the damping shaft 13, a filter screen plate 4 is installed horizontally on one side of the air inlet 2, and a handle 5 is installed on one end of the filter screen plate 4 located outside the air inlet 2, and the setting of the handle 5 can facilitate personnel to pull out the filter screen plate 4 from one side of the air inlet 2 for cleaning.

[0022] See also Figure 2-3 An exhaust pipe 8 is installed on the upper part of the cabinet 1, an upper cover 9 is installed on the exhaust pipe 8, a filter screen cover 12 is installed on the bottom surface of the upper cover 9, a cooling fan 11 is installed on the top of the cabinet 1, the cooling fan 11 is powered by an external power supply, the filter screen cover 12 covers the cooling fan 11, and air outlets 10 are evenly spaced on the four sides of the exhaust pipe 8. The upper cover 9 is plugged and fixed to the upper pipe opening of the exhaust pipe 8. This design makes it easy to open the upper cover 9 and take out the filter screen cover 12 for cleaning. The bottom end of the filter screen cover 12 is in contact with the top surface of the cabinet 1. This design allows the inner cavity of the filter screen cover 12 to be connected to the cabinet 1, so as to prevent dust in the external air from entering the cabinet 1 through the air outlet 10 when the cabinet is not in use.

[0023] See also Figure 1-2 Horizontal mounting frames 6 are installed on the inner walls of both sides of the cabinet 1, and vertical mounting frames 7 are installed on the horizontal mounting frames 6 by bolts. The vertical mounting frames 7 are provided with mounting holes at equal intervals from top to bottom. The vertical mounting frames 7 can facilitate the installation of radio and television transmitters and related equipment.

[0024] When in use, the cooling fan 11 draws the hot air in the cabinet 1 upward, and the hot air is discharged through the air outlet 10 on the side of the exhaust pipe 8. At the same time, fresh air from outside enters the cabinet 1 through the air inlet 2. When the external gas enters the air inlet 2, the inclined baffle 3 can block some dust in the air, reduce the filtering pressure of the filter plate 4, reduce the cleaning frequency of the filter plate 4, and play a role in blocking water, thereby improving the waterproof effect of the cabinet 1. After passing through the baffle 3, the air is filtered by the filter plate 4 and then enters the cabinet 1. The airflow drives the heat in the cabinet 1 to be discharged from the top of the cabinet 1, and then discharged from the air outlet 10 to complete the heat dissipation. When the cabinet 1 is overheated and needs emergency heat dissipation, the baffle 3 can be directly moved to increase the effective ventilation area between the baffles 3 and the baffles 3, thereby improving the air circulation efficiency and thus improving the heat dissipation efficiency.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
