Description

Technical Field

[0001] This utility model relates to the technical field of line anti-aging devices, and in particular to an anti-aging device for broadcast television signal transmission lines. Background Technology

[0002] Broadcast and television signal transmission systems are the core infrastructure for information dissemination, and their stability directly affects the coverage quality and user experience of broadcast and television programs. As the physical carrier of signal transmission, lines such as coaxial cables, optical fibers, and microwave feeders are exposed to complex environments for extended periods, making them susceptible to external factors such as temperature, humidity, ultraviolet radiation, and chemical corrosion. This leads to material aging and performance degradation, subsequently causing signal attenuation and interruptions. Therefore, the research and application of anti-aging equipment is crucial for ensuring the reliability and lifespan of transmission systems.

[0003] A search revealed a device for preventing aging of broadcast television signal transmission lines (publication number CN218414071U). This device provides heat dissipation for the transmission lines. The device includes a mounting frame, mounting fixtures, guide components, hinges, and a cover plate. The mounting fixture is bolted to the front of the mounting frame. Multiple guide components are connected to both sides of the mounting fixture. A hinge is rotatably connected to the upper side of the mounting fixture, and a cover plate is connected to the hinge, contacting the mounting fixture. This invention, through the cooperation of the mounting fixture and the cover plate, protects the line, while a cooling fan dissipates heat, thus preventing overheating and damage to the line.

[0004] Based on the aforementioned patent, the installation fixture and cover plate work together to protect the cable, while the cooling fan dissipates heat from the cable. This prevents the cable from overheating and causing damage and aging. However, the heat load distribution of cables varies significantly under different environments and operating conditions. For example, the temperature difference between the section exposed to direct sunlight and the section shaded from the environment can reach more than 20°C. In existing patents, the fan is fixedly installed at a specific point, and the heat dissipation range is limited to the area near the fan outlet, usually 0.5-1.5 meters, which is difficult to cover the entire cable section. For example, when the middle of the cable experiences an abnormal temperature rise due to increased local resistance or external high temperature, the fixed fan cannot move to the hot area in time, leading to accelerated aging of the overheated section. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-aging device for broadcast television signal transmission lines. This device utilizes friction to push the fan casing along the cable axis to the area to be cooled, thereby achieving dynamic directional heat dissipation, maintaining a constant water temperature, and forming a closed-loop cooling system of water cooling circulation, air cooling, and semiconductor refrigeration to ensure efficient heat dissipation of the cable.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-aging device for broadcast television signal transmission lines includes a fan housing. A fixing frame is fixedly connected to the inner walls of both the left and right ends of the fan housing. A drive motor is fixedly connected to the outer wall of the front end of each fixing frame. The drive end of the drive motor is connected to a second transmission wheel and a first transmission wheel via a transmission assembly. A transition ring is rotatably connected to the front and rear ends of the second and first transmission wheels. A connecting frame is fixedly connected to the front end of the fan housing. Fixing rings are fixedly connected to both the left and right ends of the connecting frame. A cooling fan is installed on the inner wall of each fixing ring.

[0008] Furthermore, the transmission assembly includes a gear column fixedly connected to the drive end of the drive motor, a face gear one fixedly connected to the front end of each of the two transmission wheels, and a face gear two fixedly connected to the front end of each of the two transmission wheels. The inner diameter of the gear column meshes with the outer diameter of the front end of the face gear one and the face gear two, respectively.

[0009] Furthermore, the outer walls of the two transition rings of the transmission wheel are slidably connected to the inner wall of the front end of the fixed frame, and the outer wall of the one transition ring of the transmission wheel is fixedly connected to the inner wall of the front end of the fixed frame.

[0010] Furthermore, a transmission screw is rotatably connected to the bottom end of the inner wall of the fixed frame, and an adapter block is threadedly connected to the outer wall of the transmission screw.

[0011] Furthermore, the left end of the adapter block is rotatably connected to the outer wall of the front adapter ring at the second transmission wheel, and the rear end of the adapter block is slidably connected to the inner wall of the front end of the fixed frame.

[0012] Furthermore, a water tank is fixedly connected to the bottom of the fan casing, and a semiconductor cooling chip is installed on the bottom of the inner wall of the water tank.

[0013] Furthermore, a water pump is installed on the left end of the inner wall of the water tank, and a delivery pipe is fixedly connected to the drive end of the water pump. The other end of the delivery pipe is fixedly connected to the top of the water tank and passes through it. A water inlet is fixedly connected to the left end of the water tank.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, after the fan housing is installed, the second transmission wheel and the first transmission wheel are set on the surface of the cable. The rotating transmission screw drives the adapter block to move along the fixed frame. The adapter ring drives the second transmission wheel to move closer to the first transmission wheel to adjust the clamping distance. The external control device starts the drive motor, and the gear column links the second surface gear and the first surface gear to drive the second transmission wheel and the first transmission wheel to rotate in opposite directions. The friction force pushes the fan housing to move along the cable axis to the area to be cooled, so as to realize dynamic directional heat dissipation.

[0016] 2. In this invention, when the cooling fan starts, the cooling water in the water tank is pumped into the delivery pipe by the water pump. During the circulation, the cooling energy is transferred to the air through the pipe wall, and the cooling fan blows the cool air towards the cable to enhance the cooling effect. The cooling water returning to the water tank is cooled a second time by the semiconductor cooling chip to maintain a constant water temperature, forming a closed-loop cooling system of "water cooling circulation + air cooling + semiconductor cooling" to ensure efficient heat dissipation of the cable.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an anti-aging device for broadcast television signal transmission lines, comprising a fan housing 1, with fixed frames 7 fixedly connected to the inner walls of both the left and right ends of the fan housing 1, and drive motors 15 fixedly connected to the outer walls of the front ends of the fixed frames 7. The drive ends of the drive motors 15 are respectively connected to transmission wheels 18 and 17 via a transmission assembly. Adapter rings 19 are rotatably connected to the front and rear ends of transmission wheels 18 and 17. The transmission assembly includes a gear column 14 fixedly connected to the drive end of the drive motor 15, and face gears 13 fixedly connected to the front ends of transmission wheels 18. The front end of each of the transmission wheels 17 is fixedly connected to a face gear 16. The inner diameter of the gear column 14 meshes with the outer diameter of the front end of the face gear 13 and the face gear 16 respectively. The outer wall of the adapter ring 19 at the transmission wheel 18 is slidably connected to the inner wall of the front end of the fixed frame 7. The outer wall of the adapter ring 19 at the transmission wheel 17 is fixedly connected to the inner wall of the front end of the fixed frame 7. The bottom end of the inner wall of the fixed frame 7 is rotatably connected to a transmission screw 8. The outer wall of the transmission screw 8 is threadedly connected to an adapter block 12. The left end of the adapter block 12 is rotatably connected to the outer wall of the front adapter ring 19 at the transmission wheel 18. The rear end of the adapter block 12 is slidably connected to the inner wall of the front end of the fixed frame 7.

[0026] Specifically: After the fan housing 1 is fixed to the cable surface by the mounting fixture, its built-in transmission wheel 2 18 and transmission wheel 17 are symmetrically fitted onto the outer wall of the cable through the wheel groove structure. At this time, the operator can rotate the transmission screw 8 manually or by motor drive. Utilizing the fit between the screw thread and the internal thread hole of the adapter block 12, the adapter block 12 is driven to move axially along the guide rail of the fixed frame 7. Simultaneously, the adapter block 12 is connected to the wheel frame of transmission wheel 2 18 through the hinged adapter ring 19, thereby synchronously driving transmission wheel 2 18 to move towards transmission wheel 17, realizing the active adjustment of the distance between the two transmission wheels. When the external control device starts the drive motor 15, the output shaft of the drive motor 15 drives the coaxially connected gear column 14 to rotate. The gear column 14 rotates through the end face teeth... The structure is respectively fixed to the shaft end of the second transmission wheel 18 by the second face gear 16 and fixed to the shaft end of the first transmission wheel 17 by the first face gear 13. This meshes with the transmission wheel 18 and the first transmission wheel 17 to drive them to rotate synchronously in opposite directions. Since the two transmission wheels are in contact with the cable surface through friction, the tangential force generated by their reverse rotation will push the fan housing 1 to move along the cable axis, thereby realizing the dynamic displacement of the heat dissipation equipment. It can accurately position the local high temperature area of ​​the cable for directional air cooling, effectively solving the problem that traditional heat dissipation equipment cannot dynamically respond to the heat load distribution, and significantly improving the heat dissipation efficiency and equipment utilization.

[0027] Reference Figure 2 and Figure 5A connecting frame 2 is fixedly connected to the front end of the fan housing 1. A fixing ring 3 is fixedly connected to both the left and right ends of the connecting frame 2. A cooling fan 9 is installed on the inner wall of the fixing ring 3. A water tank 4 is fixedly connected to the bottom end of the fan housing 1. A semiconductor cooling chip 11 is installed on the bottom end of the inner wall of the water tank 4. A water pump 10 is installed on the left end of the inner wall of the water tank 4. A delivery pipe 6 is fixedly connected to the drive end of the water pump 10. The other end of the delivery pipe 6 is fixedly connected to the top of the water tank 4 and passes through it. A water inlet 5 is fixedly connected to the left end of the water tank 4.

[0028] Specifically: When the cooling fan 9 starts, a temperature sensor integrated inside the water tank 4 monitors the cooling water temperature in real time. If the detected water temperature is higher than a preset threshold, such as 30°C, the water pump 10 and the semiconductor cooling chip 11 are activated in conjunction. The water pump 10 draws cooling water from the water tank 4 through the inlet 4a, pressurizes it, and delivers it to the copper delivery pipe 6 spirally wound around the air outlet of the cooling fan 9; the cooling water flows in the delivery pipe 6 at a rate of 0.5-1.2... The circulating flow rate of L / min allows for rapid heat transfer to the tube wall via the high thermal conductivity of the copper tube, forcibly cooling the air flowing outside the delivery tube 6. The temperature difference can reach 15-25℃. The cooled air is then blown onto the cable surface by the cooling fan 9 in an axial airflow mode, forming a directional airflow that directly reduces the temperature of the cable's outer sheath and conductor. The cooling water that has completed heat exchange returns to the water tank 4 from the outlet of the delivery tube 6 via the return pipe. The semiconductor cooling chip 11 is a prior art technology, including a series of refrigeration devices such as a compressor and condenser, which will not be described in detail here. At this time, the cold end face of the semiconductor cooling chip 11 is in close contact with the inner wall of the water tank 4, and the minimum operating temperature can reach -10℃. Through the Peltier effect, the water temperature is cooled a second time to the initial set value, thus forming a closed-loop cooling system. This significantly improves heat dissipation efficiency and energy utilization, solving the problems of traditional single air-cooled heat dissipation equipment being easily affected by ambient temperature and having insufficient endurance.

[0029] Working principle: After the fan casing 1 is installed at the cable, and the second transmission wheel 18 and the first transmission wheel 17 are fitted onto the cable surface, the transmission screw 8 can be rotated to drive the adapter block 12 to move on the surface of the fixed frame 7. This allows the adapter block 12 to drive the second transmission wheel 18 to move within the fixed frame 7 via the adapter ring 19, shortening the distance between the second transmission wheel 18 and the first transmission wheel 17. When the drive motor 15 is started by the external control device, it drives the gear column 14 to transmit power to the second face gear 16 and the first face gear 13, causing the second transmission wheel 18 and the first transmission wheel 17 to rotate relative to each other, thus allowing the transmission wheels to move. The second transmission wheel 18 and the first transmission wheel 17 move on the surface of the cable, making it convenient for the second transmission wheel 18 and the first transmission wheel 17 to move the fan housing 1 to the location where the cable needs to be cooled. When the cooling fan 9 is started to dissipate heat, the cooling water preset in the water tank 4 is transported by the water pump 10, so that the cooling water circulates in the delivery pipe 6, thereby conducting the low temperature generated in the delivery pipe 6 to the surrounding air, and being transported by the cooling fan 9 to form cold air to improve the cooling effect on the cable. After the water in the delivery pipe 6 flows back to the water tank 4, it is cooled again by the semiconductor cooling chip 11, thereby maintaining the low temperature effect of the cooling water in the water tank 4.
