Description

Technical Field

[0001] This utility model relates to the technical field of signal stabilizers and enhancers for broadcast and television transmitters, and in particular to signal stabilizers and enhancers for broadcast and television transmitters. Background Technology

[0002] In broadcasting and television engineering, signal stabilizers and enhancers are crucial devices for addressing the special needs of complex transmission environments. Their application not only directly alleviates problems such as image stuttering and sound distortion caused by signal attenuation and interference, improving the audience's reception experience, but also provides key support for optimizing broadcasting and television transmission systems. Through signal strength monitoring and anti-interference performance debugging, engineers can accurately control transmission quality and adjust deployment plans accordingly. This effectively reduces the impact of environmental factors on transmission performance, creating conditions for high-quality coverage and long-term operation of broadcasting and television projects.

[0003] However, existing signal stabilizers and enhancers for broadcast television transmitters have the following drawbacks:

[0004] (1) Common broadcast television transmitter signal enhancement devices have insufficient vibration reduction structure design, rely on simple shell protection, lack the cooperation of elastic vibration reduction components and auxiliary vibration reduction components, and are prone to buffering displacement during vibration, which cannot effectively absorb the impact force. The signal module and internal components are easily damaged by vibration.

[0005] (2) Common radio and television transmitter signal enhancement devices rely on bolts and other fixed structures for installation and disassembly. They require additional tools and the process is complicated and time-consuming. The locking type devices lack effective guide and limit structures, which can easily lead to loosening of the locking mechanism.

[0006] Therefore, this utility model provides a signal stabilizer and enhancer for broadcast television transmitters. Utility Model Content

[0008] The problem solved by this utility model is to provide a highly practical signal stabilizer and enhancer for broadcast television transmitters, which solves the problems of lack of shock absorption structure and cumbersome disassembly and assembly process mentioned in the background art.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a signal stabilizer and enhancer for a broadcast television transmitter, comprising an enhancer body, a first cavity inside the enhancer body, a buffer plate slidably connected inside the first cavity, a first spring connected between the bottom of the buffer plate and the opposite side of the first cavity, a signal module fixedly connected to the top of the buffer plate, a connecting wire fixedly connected to the top of the signal module, a connecting post fixedly connected to the top of the connecting wire, a fixed post rotatably connected to the top of the connecting post, a connecting plate fixedly connected to the top of the fixed post, an antenna rotatably connected to the surface of the connecting plate, a locking plate fixedly connected to the bottom of the enhancer body, a second cavity inside the locking plate, a limit plate slidably connected inside the second cavity, a second spring connected between one side of the limit plate and the opposite side of the second cavity, and a button and a locking block fixedly connected to the other side of the limit plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4This utility model provides a technical solution: a signal stabilizer and enhancer for a broadcast television transmitter, including an enhancer body 1. The enhancer body 1 has a first cavity inside, and a buffer plate 2 is slidably connected inside the first cavity. The buffer plate 2, in conjunction with a first spring 3 at its bottom, forms an elastic vibration damping structure, dispersing vibration impact force through its own sliding motion. The bottom of the buffer plate 2 and the opposite side of the first cavity are connected to the first spring 3. A signal module 4 is fixedly connected to the top of the buffer plate 2. A connecting line 5 is fixedly connected to the top of the signal module 4. A connecting post 6 is fixedly connected to the top of the connecting line 5. A fixing post 7 is rotatably connected to the top of the connecting post 6. A connecting plate 8 is fixedly connected to the top of the fixing post 7, providing a rotation fulcrum for an antenna 9. Combined with the angle adjustment function of the antenna 9, this allows the antenna 9 to accurately adapt to different signal propagation paths. Antenna 9 is rotatably connected to the surface of the receiving plate 8. A locking plate 10 is fixedly connected to the bottom of the booster body 1. A second cavity is opened inside the locking plate 10. A limiting plate 11 is slidably connected inside the second cavity. A second spring 12 is connected between one side of the limiting plate 11 and the opposite side of the second cavity. The spring 12 provides restoring force by its own elastic deformation. When the button 13 is released, it pushes the limiting plate 11 to drive the locking block 14 to pop out and engage. The button 13 and the locking block 14 are fixedly connected to the other side of the limiting plate 11. The booster body 1 is made of 304 stainless steel with a thickness of 3-5mm. The depth of the first cavity is set to 8-12cm. The elastic coefficient of the first spring 3 is 2-3N / mm. The locking block 14 is made of high manganese steel with a surface quenching treatment and a hardness of HRC45-50 to ensure the engagement strength.

[0027] The surface of the booster body 1 is equipped with an indicator light 15. When the device is successfully connected, the indicator light 15 starts to flash. The indicator light 15 transmits the connection ready signal through flashing, which makes it convenient for engineering technicians to quickly confirm the working status of the device and avoid signal enhancement failure due to incomplete connection. The indicator light 15 uses an LED light source with a rated voltage of 12V, a flashing frequency of 2-3 times / second, and a luminous intensity of ≥800mcd. The shell is made of PC transparent material with a protection level of IP65, which is suitable for harsh outdoor environments.

[0028] A buffer pad 16 is fixedly connected to the inner wall of the first cavity. The buffer pad 16 has a honeycomb design. Utilizing the porous buffering characteristics of the honeycomb design, it increases the vibration damping contact area, evenly disperses the vibration impact force, and further strengthens the vibration damping protection of the signal module 4 and its internal components. The buffer pad 16 is made of EVA foam material with a density of 0.9-1.1 g / cm³, a thickness of 2-3 cm, a honeycomb pore size of 8-10 mm, and a porosity of ≥75%. It can absorb vibration energy with a frequency of 5-500 Hz and has a vibration damping efficiency of over 85%.

[0029] A rotating shaft is rotatably connected to the center of the connecting plate 8, and an antenna 9 is rotatably connected to the surface of the rotating shaft, providing a flexible mounting base for the antenna 9. The rotational characteristics of the rotating shaft enable multi-directional adjustment of the antenna 9's transmit and receive angles. The rotating shaft is made of 45# steel, with a diameter of 8-10mm, and is hard chrome plated. The coefficient of friction is ≤0.15. The antenna 9 can achieve 0-360° horizontal rotation and -45° to 90° pitch adjustment, with an adjustment damping of 0.5-1N・m, ensuring a fixed and stable angle.

[0030] The surface of the booster body 1 is provided with ventilation slots. The ventilation slots are rectangular in design, which increases the heat dissipation area and accelerates the dissipation of internal heat during operation, thus preventing the performance of components from deteriorating or being damaged due to heat accumulation. The ventilation slots are 20mm×80mm in size, and there are 3 sets in total. The total heat dissipation area is ≥0.015m². Dustproof nets are installed inside the slots. The mesh size is 0.5-1mm, which can keep the internal temperature of the device below 60℃ and improve the heat dissipation efficiency by more than 40%.

[0031] The inner wall of the second cavity has a limiting groove, and a limiting plate 11 is slidably connected inside the limiting groove to prevent the limiting plate 11 from shifting or getting stuck when sliding in the second cavity, thus ensuring the linkage stability between the limiting plate 11 and the locking block 14. The limiting groove is 12-15mm wide and 3-5mm deep. The limiting plate 11 is made of ABS engineering plastic with a thickness of 8-10mm and a sliding stroke of 15-20mm. With the elastic recovery of the second spring 12, the locking response time is ≤0.3 seconds and the number of repeated uses is ≥10,000 times.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When using the device, place the booster body 1 at the target deployment position. The elastic vibration damping structure composed of the buffer plate 2 and the first spring 3 in the first cavity inside, together with the honeycomb-shaped buffer pad 16, can automatically absorb the impact of environmental vibration and protect the signal module 4 and internal components. Then, rotate the pivot at the center of the connecting plate 8 to adjust the antenna 9 to the appropriate signal transmission and reception angle. Observe the signal light 15 on the surface of the booster body 1. When the signal light 15 starts to flash, it indicates that the signal connection is successful and ensures stable signal transmission.

[0034] The second step: When using this device, during installation, press the button 13 on the side of the clamping plate 10. The button 13 causes the limiting plate 11 to slide within the limiting groove on the inner wall of the second cavity, compressing the second spring 12 and causing the clamping block 14 to retract synchronously. After aligning the clamping plate 10 with the mounting slot, release the button 13, and the clamping block 14 will pop out to complete the locking and fixing. During disassembly, press the button 13 again, causing the limiting plate 11 to slide and compress the second spring 12. The clamping block 14 will retract and disengage from the slot, allowing the device to be quickly removed. No additional tools are required throughout the process, making the operation convenient and efficient.
