A fixing post 18 is fixedly connected to the top of the spring 21 and damping rod 19. Clamping plates 14 are fixedly connected to both the left and right ends of the fixing post 18. An insert plate 23 is fixedly connected to the rear side of the fixing post 18. A limit block 24 is fixedly connected to the end of the insert plate 23. A mounting block 12 is fixedly connected to the inner side of the clamping block 13. A power module 10 is mounted on the left front end of the mounting block 12. A signal amplifier 9 is mounted on the right side of the power module 10. The signal amplifier 9 is the core component, and its main function is to amplify the received weak broadcast television signal to improve signal strength. The strength and quality of the number are determined by pressing the clamp 14, causing the fixing post 18 and the insert plate 23 to move along the damping rod 19 in the pressing direction, aligning the insert plate 23 with the slot 25 and inserting it in. After the insert plate 23 is aligned with the slot 25, the clamp 14 is released, and the spring 21 returns to its original position, causing the insert plate 23 and the limiting block 24 to move along the damping rod 19 in the direction of the spring 21's return. The insert plate 23 then engages in the slot 25, fixing the clamping block 13 and the clamping block 27, which simultaneously fixes the signal amplifier 9. The operation is simple and easy to install. The inner wall of the protective shell 1 is on the left and right sides. Each side is equipped with a heat dissipation mechanism 2, which is used to cool down the signal amplifier 9 and prevent the temperature from rising and affecting its performance and stability. A base 3 is installed on the right side of the top wall of the protective shell 1, and an antenna 4 is installed on the top of the base 3. The antenna 4 is responsible for receiving broadcast television signals. A dust cover 5 is installed on the front side of the outer wall of the protective shell 1. The dust cover 5 can effectively block dust particles in the air from entering the interior of the protective shell 1, and prevent dust from accumulating on the signal amplifier 9, thereby ensuring the stable performance of the equipment and preventing excessive dust from affecting signal reception and transmission.

[0034] Specifically, pressing the clamp 14 causes the fixing post 18 and the insert plate 23 to move along the damping rod 19 in the pressing direction, aligning the insert plate 23 with the slot 25. After the insert plate 23 is aligned with the slot 25, the clamp 14 is released, and the spring 21 returns to its original position, causing the insert plate 23 and the limiting block 24 to move along the damping rod 19 in the direction of the spring 21's return. The insert plate 23 then engages in the slot 25, fixing the first clamp 13 and the second clamp 17, which simultaneously fixes the signal amplifier 9. The operation is simple and easy to install.

[0035] Reference Figure 2 , Figure 3 and Figure 6The heat dissipation mechanism 2 includes a battery 201, which is installed on the left and right sides of the inner wall of the protective shell 1. A wire 203 is installed on the bottom outer side of the battery 201, and a motor 205 is installed at the end of the wire 203. A fan 204 is fixedly connected to the output end of the motor 205. Multiple fixing clips 202 are fixedly connected at equal intervals to the front side of the fan 204. A condenser pipe 206 is installed on the fixing clip 202. The condenser pipe 206 is started to generate cold air, which then activates the fan 204. The fan 204 blows air towards the signal amplifier 9. The temperature of the air drops rapidly as it passes through the condenser pipe 206. The fan 204 continues to rotate, distributing the cold air... The air is blown towards the signal amplifier 9 to ensure uniform coverage of the cool air, thereby reducing the temperature inside the protective shell 1 and preventing high temperature from affecting the performance of the equipment. The bottom of the protective shell 1 is fixedly connected with brackets 6 at equal intervals. The rear side of the brackets 6 is threaded with bolts 7. The brackets 6 have the advantages of high strength, good stability and corrosion resistance, and can withstand a certain weight and external force. They are used to support the protective shell 1 and other internal components. The bottom right side of the power module 10 is equipped with a second wire 26. The end of the second wire 26 is equipped with a data reader 16. The data reader 16 decodes the received broadcast television signal and converts it into a format that can be processed and understood by other components.

[0036] Specifically, the condenser 206 is activated to generate cold air, and then the fan 204 is activated. The fan 204 blows air towards the signal amplifier 9. The temperature of the air drops rapidly as it passes through the condenser 206. The fan 204 continues to rotate, blowing the cold air towards the signal amplifier 9 to ensure uniform coverage of the cold air, thereby reducing the temperature inside the protective housing 1 and preventing high temperature from affecting the performance of the equipment.

[0037] Reference Figure 1 , Figure 3 and Figure 6 A display 15 is mounted on the front side of the data reader 16, and a filter 11 is mounted on the left side of the front wall of the mounting plate 8.

[0038] Specifically, the display 15 is used to display the current signal strength, channel information, and power parameters of the power module 10, so that users can understand the working status of the equipment and make corresponding adjustments. The filter 11 is used to filter out noise and interference signals in the signal, ensuring that the output signal is purer. The filter 11 can be designed according to different broadcast television signal frequency bands, allowing only signals of specific frequency bands to pass through, thereby improving the stability and clarity of the signal.

[0039] Working principle: Pressing the clamp 14 causes the fixing post 18 and the insert plate 23 to move along the damping rod 19 in the pressing direction, aligning the insert plate 23 with the slot 25. After the insert plate 23 is aligned with the slot 25, the clamp 14 is released, and the spring 21 returns to its original position, causing the insert plate 23 and the limiting block 24 to move along the damping rod 19 in the direction of the spring 21's return. The insert plate 23 is then engaged in the slot 25, fixing the clamping block 13 and the clamping block 27, which simultaneously fixes the signal amplifier 9. The operation is simple and easy to install.

[0040] A fan 204 is fixedly connected to the output end of the motor 205. A condenser 206 is installed on the fixing clamp 202. The condenser 206 is started to generate cold air, and then the fan 204 is activated. The fan 204 blows the air towards the signal amplifier 9. The temperature of the air drops rapidly as it passes through the condenser 206. The fan 204 continues to rotate, blowing the cold air towards the signal amplifier 9 to ensure that the cold air is evenly distributed, thereby reducing the temperature inside the protective shell 1 and preventing high temperature from affecting the performance of the equipment.
