The suction cup is fixed to the lower left side of the shell, and the groove is opened to the lower front of the shell. The movable shaft is movably connected to the left and right sides of the inner wall of the groove. The device is equipped with a movable shaft. When the external wire is inserted into the power strip, the plug base can be flipped through the movable shaft, so that the plug base is not easy to bend and cause looseness and damage between the power cord; however, there are still the following deficiencies in actual use: From a practical point of view, the video compression encoding processor will generate a lot of heat during operation. Overheating will cause the processor performance to decline, resulting in problems such as slower video compression speed, reduced image quality, and weakened data processing capability, affecting the video monitoring and information display effects of the subway system.

[0004] Therefore, a high-definition video compression encoding processor for subway vehicles is needed to solve the problem in the prior art that the overheating of the video encoder affects the video monitoring and information display effects of the subway system. Utility Model Content

[0013] Compared with the prior art, the utility model provides a subway vehicle-mounted high-definition video compression encoding processor, which has at least the following beneficial effects:

[0014] (1) By setting a cooling mechanism, turning on the cooling water tank and the water pump, the water in the first water pipe and the second water pipe circulates.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a high-definition video compression encoding processor for subway vehicles, including a processor body 1, a plurality of shock-absorbing pads 2 are fixedly connected to the bottom of the processor body 1, mounting plates 3 are fixedly connected to both sides of the processor body 1 near the bottom, two positioning holes 4 are provided on the surfaces of the two mounting plates 3, a plurality of evenly distributed heat dissipation fins 5 are fixedly connected to both sides of the processor body 1, a support plate 6 is fixedly connected to the top of the processor body 1 near both sides, two clamping rods 7 are slidably connected inside the two support plates 6, springs 8 are sleeved on the outer walls of the plurality of clamping rods 7, a pull plate 9 is fixedly connected to the outer sides of every two corresponding clamping rods 7, and a cooling mechanism 10 is arranged on the top of the processor body 1.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth mentioning that the multiple heat sink fins 5 are made of silicon carbide ceramic material. Silicon carbide ceramics have good thermal conductivity and can efficiently transfer the heat generated by the processor body 1 to the surface of the heat sink fins 5, and accelerate the transmission and dissipation of heat, which helps to effectively reduce the operating temperature of the processor body 1 and maintain the stability and performance of the equipment. At the same time, silicon carbide ceramics have high chemical stability, can resist chemical corrosion and oxidation, and are not easily affected by the external environment and undergo quality changes, so that the silicon carbide ceramic heat sink fins 5 can maintain good performance under various chemical gases and humidity conditions that may exist inside the subway car.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth mentioning that the ends of the multiple clamping rods 7 are all hemispherical in design. The hemispherical ends can be more easily aligned with the interface, thereby improving the accuracy and efficiency of installation and facilitating maintenance and disassembly. At the same time, the hemispherical ends can provide better fixation and stability during connection, reducing the adverse effects caused by looseness or swinging.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that multiple springs 8 are fixedly connected between the outer side of the support plate 6 and the inner side of the pull plate 9 to ensure that the clamping rod 7 can slide flexibly inside the support plate 6, thereby realizing the detachable connection of the cooling mechanism 10 on the top of the processor body 1.

[0026] According to the above working process, it can be known that: by setting the clamping rod 7, under the action of the spring 8 and the pull plate 9, it is ensured that the clamping rod 7 can slide flexibly inside the support plate 6, thereby realizing the detachable connection of the cooling mechanism 10 on the top of the processor body 1, which is convenient for the installation and disassembly of the cooling mechanism 10 and saves maintenance time and repair costs.

[0027] Further as Figure 4As shown, it is worth specifically explaining that the cooling mechanism 10 includes a protective cover 1001 detachably connected to the top of the processor body 1, two clamping holes 1002 corresponding to the clamping rod 7 are arranged on both sides of the protective cover 1001, two heat dissipation fans 1003 are installed on the top of the protective cover 1001, and a water pump 1004 and a cooling water tank 1005 are installed at the rear end of the protective cover 1001. A first water pipe 1006 and a second water pipe 1007 are fixedly connected between the water pump 1004 and the cooling water tank 1005. By setting the cooling mechanism 1 0, the second water pipe 1007 takes out the heat generated by the operation of the processor body 1 inside the protective cover 1001, thereby reducing the temperature of the processor body 1. At the same time, the second water pipe 1007 cooperates with the heat dissipation fan 1003. The wind blown by the heat dissipation fan 1003 is transformed into cold wind under the action of the second water pipe 1007 and acts on the processor body 1, which has a good cooling effect on the processor body 1, thereby ensuring that the performance and stability of the processor body 1 are not affected, and ensuring the normal operation of functions such as subway video monitoring and information display.

[0028] Further as Figure 4 As shown, it is worth explaining in detail that the inner wall of the snap-in hole 1002 fits tightly with the outer wall of the snap-in rod 7. The tight fit can ensure that there is no gap between the inner wall of the snap-in hole 1002 and the outer wall of the snap-in rod 7, thereby improving the stability of the connection. Such a design can prevent loosening during vibration or movement and maintain the firmness of the connection.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that the second water pipe 1007 penetrates into the interior of the protective cover 1001, and the second water pipe 1007 is designed in a serpentine shape, which increases the contact area of ​​the second water pipe 1007 inside the protective cover 1001, making the heat exchange more sufficient and the cooling effect better.

[0030] This solution has the following working process: during actual use, while the processor body 1 is running, the cooling water tank 1005 and the water pump 1004 are turned on, and the water in the first water pipe 1006 and the second water pipe 1007 circulates. Under the action of the cooling water tank 1005, the heat generated by the operation of the processor body 1 inside the protective cover 1001 is brought out by the second water pipe 1007, thereby reducing the temperature of the processor body 1. At the same time, the second water pipe 1007 cooperates with the heat dissipation fan 1003. The wind blown out by the heat dissipation fan 1003 is converted into cold wind under the action of the second water pipe 1007 and acts on the processor body 1, thereby cooling the processor body 1. When disassembly is required, only the pull plate 9 needs to be pulled outward to remove the clamping rod 7 from the clamping hole 1002, and then the protective cover 1001 is lifted up.

[0031] In summary: by setting up the cooling mechanism 10, the second water pipe 1007 brings out the heat generated by the operation of the processor body 1 inside the protective cover 1001, thereby reducing the temperature of the processor body 1. At the same time, the second water pipe 1007 cooperates with the heat dissipation fan 1003, and the wind blown by the heat dissipation fan 1003 is transformed into cold wind under the action of the second water pipe 1007 and acts on the processor body 1, which has a good cooling effect on the processor body 1, thereby ensuring that the performance and stability of the processor body 1 are not affected, and ensuring the normal operation of functions such as subway video monitoring and information display; by setting up the clamping rod 7, under the action of the spring 8 and the pull plate 9, it is ensured that the clamping rod 7 can slide flexibly inside the support plate 6, thereby realizing the detachable connection of the cooling mechanism 10 at the top of the processor body 1, facilitating the installation and disassembly of the cooling mechanism 10, and saving maintenance time and repair costs.
