Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency receivers, and in particular to a radio frequency receiver capable of suppressing interference signals. Background Art

[0002] An ideal receiver suppresses all unwanted noise, including other signals, and does not add any noise or interference to the desired signal. Regardless of the form or format of the signal, it can be transformed to fit the characteristics required by the signal processor detection circuit and then sent to the intelligent user interface.

[0003] Existing RF receivers place sealing gaskets, usually made of rubber, at the contact edge of the box cover and the box body, and then use screws to tightly fix the box cover and the box body together. The screws are distributed on the edge of the box body. By tightening the screws, the box cover and the box body fit tightly together, and the sealing gasket is squeezed and deformed to fill the tiny gap between the two, thereby achieving sealing. When the internal components of the receiver generate heat, the heat will be transferred to the chassis shell by heat conduction. There is a temperature difference between the chassis shell and the surrounding air. According to the principle of thermal convection, hot air rises and cold air is replenished, thereby taking away the heat from the surface of the shell to achieve heat dissipation. In some traditional RF receivers with higher power, metal heat sinks are installed on the surface of the main heating components (such as power amplifiers). After the heat of the heating components is transferred to the heat sink, the heat sink uses its large surface area to exchange heat with the surrounding air to achieve the purpose of heat dissipation.

[0004] Existing devices are easily affected by environmental factors (such as temperature changes, chemical corrosion, ultraviolet radiation, etc.) and may age, deform or be damaged, resulting in a decrease in sealing performance. The screw removal process is relatively cumbersome, especially for large RF receivers with a large number of screws. Both disassembly and installation take a long time, which is not conducive to the rapid maintenance and overhaul of the equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a radio frequency receiver capable of suppressing interference signals, which solves the problems in the background art that the sealing effect of the box is limited, the heat dissipation efficiency of the radio frequency receiver is low, and it is difficult to maintain a stable temperature.

[0015] By adopting the above technical solution, the coolant storage tank is used to store the coolant, and when the valve is opened, the coolant enters the copper tube from the first pipeline, thereby realizing the cooling operation of the radio frequency receiver.

[0016] As a further description of the above technical solution: a second pipe is fixedly connected to one side of the rear end of the copper tube, and one end of the outer wall of the second pipe is fixedly connected to the top rear end of the coolant storage tank.

[0017] By adopting the above technical solution, the coolant absorbs the remaining heat of the copper tube and flows into the second pipe, thereby realizing the circulation operation of the coolant inside the coolant storage tank.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0032] Combination Figure 1-Figure 4 The present invention discloses a radio frequency receiver capable of suppressing interference signals, comprising a box body 1, a box cover 2 is arranged on the top of the box body 1, and the box cover 2 cooperates with the box body 1. A radio frequency receiver 13 is arranged at the bottom of the inner wall of the box body 1, and the radio frequency receiver 13 is the core component of the whole device, and its main function is to receive radio frequency signals.

[0033] The box body 1 cooperates with the box cover 2 to provide physical protection for the RF receiver 13 to prevent external physical impact, dust, moisture and other factors from causing damage to the internal components.

[0034] The top of the outer wall of the box body 1 is fixedly connected with a lock shell 9 all around, the bottom of the inner wall of the lock shell 9 is fixedly connected with a threaded sleeve 19, the top of the inner wall of the lock shell 9 is rotatably connected with fixing clips 15 on both sides, the bottom of each fixing clip 15 is penetrated and slidably connected with a moving block 16, the moving block 16 is fixedly connected with the same pull rod 17 facing the same end, the bottom of the pull rod 17 is rotatably connected with a threaded rod 20, and the outer wall of the threaded rod 20 is threadedly connected to the inner wall of the threaded sleeve 19, and the bottom of the threaded rod 20 is fixedly connected with a rotating handle 18.

[0035] The outer wall bottom of the box cover 2 is fixedly connected with lock buckles 10 all around, and each lock buckle 10 is arranged one by one with the adjacent lock shell 9. The inner wall of each lock buckle 10 can contact the top of the corresponding fixing clip 15, and the rotating handle 18 is turned to drive the threaded rod 20 to rotate and move in the threaded sleeve 19, prompting the pull rod 17 to pull the moving block 16, so that the fixing clip 15 rotates and is fixed to the lock buckle 10.

[0036] The bottom of the box cover 2 and the top of the box body 1 are both fixedly connected with a sealing gasket 11 .

[0037] An absorbing material sheet 12 is fixedly connected to the inner wall of the box body 1 , and the absorbing material sheet 12 can absorb the radio frequency signal reflected by the inner wall of the box body 1 , thereby reducing the interference of the signal reflection on the signal received by the radio frequency receiver 13 .

[0038] The sealing gasket 11 is combined to complete the sealing of the box body 1 and the box cover 2, and the first electromagnetic shielding is constructed for the RF receiver 13 to block most external interference signals. The absorbing material sheet 12 handles the residual electromagnetic interference, ensures the purity and stability of the received signal, and reduces internal signal reflection and scattering. The sealing of the internal RF receiver 13 by the box body 1 and the box cover 2 can reduce the impact of external water and dust on the RF receiver 13 inside the box body 1, allowing the receiver to work in harsh environments. The absorbing material sheet 12 protects the internal RF receiver 13 from impact. During maintenance, the box cover 2 can be removed by twisting the rotating handle 18 in the opposite direction, and maintenance operations can be performed on the RF receiver 13, ensuring the reliability of the device.

[0039] A cooling component for cooling the interior of the box 1 is provided at the bottom of the box 1. When the RF receiver 13 is working, the circuit components in the RF receiver 13 will generate heat. If the heat cannot be dissipated in time, the temperature of the components will increase, which will affect the performance of the components, reduce the service life of the device and even cause malfunctions. The cooling component can take away the heat from the inside of the box 1, maintain the internal temperature within a suitable range, and ensure the normal operation of the RF receiver 13 and other components.

[0040] The cooling assembly includes a base 14, which is plugged into the interior of the box 1 from bottom to top, and the outer wall of the base 14 is fixedly connected to the bottom inner wall of the box 1. A copper tube 21 is fixedly connected to the bottom of the base 14, and the outer wall of the copper tube 21 is penetrated and fixedly connected with evenly distributed heat dissipation fins 4. A first pipe 5 is fixedly connected to one side of the front end of the copper tube 21. A valve 6 is fixedly connected to the top of the outer wall of the first pipe 5.

[0041] One end of the outer wall of the first pipe 5 penetrates and is fixedly connected to the coolant storage tank 3, and one side of the rear end of the copper tube 21 is fixedly connected to the second pipe 8. The second pipe 8 and the first pipe 5 together constitute a circulation path for the coolant between the copper tube 21 and the coolant storage tank 3. One end of the outer wall of the second pipe 8 penetrates the top of the coolant storage tank 3 and is fixedly connected to the coolant storage tank 3.

[0042] The top of the outer wall of the second pipe 8 is penetrated and fixedly connected with the radiator 7. The bottom of the second pipe 8 is fixedly connected with the water pump 22, which is the power source for the coolant to circulate in the cooling system. The base 14 absorbs the heat of the RF receiver 13 and transfers it to the copper tube 21. The heat dissipation fins 4 dissipate part of the heat, and then the valve 6 and the water pump 22 are opened. The water pump 22 draws coolant from the coolant storage tank 3. The coolant enters the copper tube 21 through the first pipe 5 to absorb heat, and then enters the second pipe 8 through the copper tube 21. After being cooled by the radiator 7, it flows back to the coolant storage tank 3.

[0043] Complete cycle cooling, efficient temperature reduction, fast and stable temperature control, ensure device performance, maintain low temperature at high temperature or high load, reduce signal distortion and component damage. The stable temperature range also reduces thermal noise, optimizes signal reception, prevents component aging, extends the life of components and RF receivers, and improves reliability and continuous working ability.

[0044] Working principle: Cover the box cover 2 on the box body 1, turn the rotating handle 18, and the rotating handle 18 drives the threaded rod 20 to rotate and move in the threaded sleeve 19. When the threaded rod 20 moves, it drives the pull rod 17 to move, and the movement of the pull rod 17 drives the moving block 16 to move at the bottom of the fixed clamp 15, and the movement drives the fixed clamp 15 to rotate, fix the fixed clamp 15 and the lock buckle 10, so as to fix the box body 1 and the box cover 2. The sealing of the box body 1 is achieved, and the sealing gasket 11 further improves the sealing effect, providing the first electromagnetic shielding defense line for the radio frequency receiver 13, which can effectively block the entry of most external electromagnetic interference signals.

[0045] The absorbing material sheet 12 can absorb the remaining interference electromagnetic signals that penetrate through the tiny gaps of the sealed box 1 or from other channels (such as interfaces), greatly reducing the impact of external interference on the target signal received. The absorbing material sheet 12 can be a carbonyl iron absorbing material sheet, which can effectively suppress the leakage of internal electromagnetic signals.

[0046] The reduction of external interference signals directly improves the purity of the signal received by the receiver. Through the dual protection of sealing and the absorbing material sheet 12, the target signal entering the receiver can be received and processed more completely and accurately. The absorbing material sheet 12 can also reduce the signal loss and interference caused by the reflection and scattering of the signal inside the receiver, making the signal transmission more stable and efficient, and helping to improve the overall performance of the receiver.

[0047] The box body 1, the box cover 2 and the sealing gasket 11 can prevent dust and moisture from entering the receiver, enhance the waterproof and dustproof effect, and enable the radio frequency receiver 13 to work reliably in outdoor, humid or dusty environments. The absorbing material sheet 12 can increase the mechanical strength and stability of the box body 1, and it can play a buffering role. When the device is subjected to external mechanical impact such as collision and vibration, it absorbs and disperses the impact force to protect the internal radio frequency receiver 13 from damage.

[0048] When the RF receiver 13 needs to be maintained, the box cover 2 is removed by twisting the rotating handle 18 in the opposite direction, and the RF receiver 13 is maintained. When the RF receiver 13 is working, heat is generated, and the base 14 absorbs the heat of the RF receiver 13 and transfers the heat to the copper tube 21. The heat sink 4 dissipates part of the heat, and the valve 6 and the water pump 22 are opened, and the water pump 22 extracts the coolant in the coolant storage tank 3. The coolant enters the copper tube 21 through the first pipe 5 and absorbs the remaining heat. Then it enters the second pipe 8 through the copper tube 21, and the radiator 7 cools the coolant, and then it flows back to the coolant storage tank 3 through the second pipe 8 to achieve circulating cooling. The temperature of the device can be effectively reduced to prevent overheating, the temperature of the device can be reduced more quickly, and the temperature of the device can be timely and effectively maintained within a reasonable range to ensure the stable performance of the device.

[0049] For example, in a high temperature environment or when the device is running at high load, the temperature of the device can be kept at a relatively low level to avoid signal distortion or component damage due to excessive temperature. The device can be maintained in a relatively stable temperature range, and a stable temperature environment can reduce thermal noise and improve the quality of signal reception. Effective heat dissipation can reduce the phenomenon of accelerated aging or damage of electronic components inside the device due to overheating, greatly extending the service life of the components. Thereby extending the service life of the RF receiver 13. When the temperature of the device is controlled, the performance fluctuation of the components is reduced, the accuracy and stability of signal processing are increased, and the reliability of the equipment and the continuous working ability of the device can be improved.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
