Description

Technical Field

[0001] This utility model relates to the field of broadcasting and television engineering, specifically to a wireless data transmission box for broadcasting and television engineering. Background Technology

[0002] In broadcast television systems, wireless transmission components are centrally installed inside electrical boxes. Similar to electrical and electronic cabinets such as distribution cabinets, these boxes contain a large number of electrical components and require continuous heat dissipation to maintain the system's efficient operation.

[0003] Installing cooling fans or vents on the top of the cabinet can accelerate the exchange of heat between the inside and outside by taking advantage of the low density of hot air. However, in broadcasting and television engineering, wireless data transmission boxes are often installed outdoors. In rainy or other inclement weather, rainwater can enter the cabinet through the top openings, damaging the components and causing short circuits in the system. This not only affects the normal signal transmission of broadcasting and television but may also cause dangers such as fires.

[0004] Therefore, a wireless data transmission box for broadcast television engineering is provided. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that while vertically arranging the heat dissipation channels inside the box can improve heat dissipation efficiency, it lacks effective waterproofing measures in rainy weather.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a wireless data transmission box for broadcasting and television engineering, combined with the attached... Figure 1 and attached Figure 3 The container includes: a cabinet 1, a base 7 connected to one side of the cabinet 1 to support its installation and fixation on the corresponding facility, and a transparent window 6 installed on the side of the cabinet 1 away from the base 7 to facilitate personnel to observe the internal state of the cabinet 1 from the outside.

[0026] Using the I-shaped iron base 7, the cabinet 1 carrying the wireless transmission components of the TV signal is installed on the corresponding facilities, such as utility poles, TV trucks, wall-mounted boxes, etc., by means of bolts, nuts, or welding.

[0027] Combined with appendix Figure 2 and attached Figure 4 The top of the cabinet 1 is provided with a through hole, and a fan 3 is installed at the through hole to dissipate heat from the environment inside the cabinet 1 by exhausting air.

[0028] Firstly, by installing a fan 3 at the top, according to common sense, heat attached to the air will reduce its density and always move upwards in a space. This will draw the hot air in the relatively enclosed cabinet 1 out from the top, which conforms to the law of hot air movement and utilizes efficient heat dissipation.

[0029] A canopy 9 with multiple sloping plates on the edge and an overall isosceles trapezoidal structure is installed above the cabinet 1. Multiple support rods 10 are connected downwards to the canopy 9. The bracket is installed above the cabinet 1 using bolts and nuts. The edge of the canopy 9 is lower than the installation position of the fan 3 on the cabinet 1.

[0030] Above the mounting hole of the fan 3 on the top of the cabinet 1, a canopy 9 is added. The canopy 9 provides dust and rain protection for the cabinet 1. The hot air extracted by the fan 3 is squeezed out from the gap between the cabinet 1 and the canopy 9. The bottom of the canopy 9 extends excessively downward, so that the end path of the airflow channel between it and the cabinet 1 is vertically downward. This prevents rainwater dripping from the top from entering the cabinet 1 through the airflow channel.

[0031] Combined with appendix Figure 2-4The cabinet 1 adopts a bottom-opening structure. The bottom of the cabinet 1 is equipped with a bracket for installing wireless data transmission components. The bottom edge of the cabinet 1 is bent outward. The bracket includes a base plate 4 and multiple carrier plates 5 that are vertically connected to one side of the base plate 4 and extend into the cabinet 1 to support the installation of related components. The carrier plates 5 are provided with multiple connection holes to facilitate the installation of related components.

[0032] Based on the above, the cooling fan 3 is placed above the cabinet 1. In order to straighten the cooling air channel inside the cabinet 1 and prevent rainwater from entering through gaps on the side of the cabinet 1, the "cabinet door" is placed directly below the cabinet 1.

[0033] The bracket is installed between the base plate 4 and the bent part of the cabinet 1 using bolts and nuts. The base plate 4 is provided with multiple air holes 8 that cooperate with the fan 3. Multiple sliding rods 2 extending to the bottom of the cabinet 1 are connected downward inside the cabinet 1. The base plate 4 is provided with multiple positioning holes that slide and connect with the sliding rods 2.

[0034] The cabinet 1 adopts a pull-out switch structure, with a bracket slidably connected at the bottom. When installed inside the cabinet 1, it is fixed with multiple bolts and nuts. Two carrier plates 5 grow out from the top to directly support the installation of TV signal transmission components. The bottom is a base plate 4 containing several air holes 8, which also serves as the base plate 4 of the cabinet 1 after installation.

[0035] After the fan 3 starts running, outside air enters the cabinet 1 through the lower air hole 8. This air intake method minimizes dust entering the cabinet 1 and also effectively prevents rainwater from entering the cabinet 1.

[0036] In the specific implementation of this utility model, during the installation stage, the canopy 9 is already installed above the cabinet 1 according to the processing of the device. The bracket is pulled out from the bottom of the cabinet 1, and the various components are installed reasonably and the wiring is arranged in an orderly manner. After completion, the bracket is pushed back into the cabinet 1 along the slide bar 2. Several bolts and nuts of the same number are used to connect each other with threads to install and fix the assembled TV broadcasting components into the cabinet 1.

[0037] Before and after this step, the cabinet 1 can be installed on the target area using a base 7 by welding or threaded connection or other suitable methods.

[0038] Under normal conditions, the fan 3 on the top of the cabinet 1 runs continuously, constantly generating airflow in and out of the cabinet 1 to dissipate heat for the internal components.

[0039] When it rains, the canopy 9 above can effectively prevent rainwater from entering the cabinet 1 through the top heat dissipation holes, thus preventing it from affecting the normal operation of the transmission components and system and providing protection for the television broadcasting system.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
