Description

Technical Field

[0001] This utility model relates to the field of equipment linkage structure technology, specifically to an equipment linkage structure for a low-speed detection radar on a highway. Background Technology

[0002] Detection radar is a device that uses radio waves or microwave technology to detect and measure the speed, distance, and other characteristics of objects. Detection radar detects and measures objects by emitting radio waves or microwave signals and receiving the reflected waves of these signals. According to the Doppler effect, when a target object moves relative to the radar, the frequency of the reflected wave changes, thus allowing the object's speed to be calculated. In highway scenarios, detection radar is mainly used to monitor slow-moving vehicles to ensure road traffic safety and smooth flow. Highway low-speed detection radar is a device specifically designed to detect slow-moving vehicles on highways. This radar system uses radio waves or microwaves to detect and track vehicle speeds.

[0003] The principle of the existing low-speed detection radar equipment linkage structure on highways is generally to detect the speed of vehicles by the radar system and compare it with the set speed limit. When the vehicle speed is lower than the set limit, the radar system will trigger an alarm or notify the traffic management center so that appropriate measures can be taken. Such radar systems are usually installed in conspicuous locations on highways, such as on both sides of the lane or in the median strip, to avoid being blocked by vehicles. They can monitor the traffic conditions on highways in real time and provide real-time speed data and alarm information.

[0004] The existing equipment linkage structure for low-speed detection radar on highways is usually installed at toll stations and used in conjunction with low-speed detection radar on the highway. However, since vehicles travel on highways all day, the equipment linkage structure easily generates a lot of heat during long-term operation. The equipment usually uses a motor to control the rotation of a cooling fan to dissipate heat from the linkage structure. However, the cooling effect of the cooling fan is limited by factors such as the fan power, air volume, and the design of the ventilation holes, resulting in poor heat dissipation of the equipment linkage structure during long-term operation, which cannot meet people's needs. Utility Model Content

[0006] How can we improve the heat dissipation effect of the linkage structure of equipment that operates for extended periods?

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0015] The beneficial effects of this utility model are:

[0016] (1) This utility model uses the equipment box and the detection linkage structure together to enable the detection linkage structure to process vehicles traveling at low speeds on highways. During the operation of the detection linkage structure, heat is transferred to the air guide plate and the air guide plate is controlled to move downwards, so that the wind outside the equipment box dissipates heat on the heat absorption mounting plate and the heat conduction pipe, thereby dissipating heat on the detection linkage structure. The cooling fan and the bidirectional drive motor work together to dissipate heat on the detection linkage structure.

[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. 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 scope of protection of the present utility model.

[0026] Please refer to the attached diagram. Figure 1-6As shown in the figure, a device linkage structure for a low-speed detection radar on a highway is applied to a display screen on a highway. The display screen can display information such as vehicle license plate numbers. The structure includes a device box 1, a detection linkage structure 2 disposed inside the device box 1, and a heat dissipation mechanism installed inside the device box 1 to dissipate heat from the detection linkage structure 2. Several sets of height-adjustable support feet are installed at the bottom of the device box 1. The detection linkage structure 2 includes a radar sensor 3 detachably installed inside the device box 1, a data processing module 4 connected to the radar sensor 3, and a linkage execution module 5 connected to the data processing module 4. The radar sensor 3 is responsible for real-time monitoring of vehicle speeds on the highway and transmitting the data to the data processing module 1. Processing module 4 receives data transmitted from radar sensor 3, processes and analyzes the data, and determines whether the vehicle speed is lower than a set value. Linkage execution module 5 can issue an alarm to remind staff that a vehicle is traveling at low speed. Linkage execution module 5 is connected to the display screen via a signal. Based on the judgment result of data processing module 4, linkage execution module 5 takes corresponding measures, such as reminding the low-speed vehicle through the display screen. The heat dissipation mechanism includes a detachable support filter cover 6 installed on the bottom inner side of the equipment box 1, a detachable heat-absorbing mounting plate 7 installed on the upper end of the support filter cover 6, several sets of heat-conducting pipes 8 vertically installed at the bottom end of the heat-absorbing mounting plate 7, and thermal expansion and contraction components movable inside the heat-conducting pipes 8. 9. The support filter cover 6 supports the heat-absorbing mounting plate 7 while preventing external dust from entering the equipment box 1. The heat pipe 8 transfers heat from the heat-absorbing mounting plate 7 to the thermal expansion and contraction component 9, causing the thermal expansion and contraction component 9 to expand due to heat. The heat dissipation mechanism also includes a guide plate 10 detachably mounted on the bottom of the thermal expansion and contraction component 9 and several sets of heat dissipation fins 11 detachably mounted on the bottom of the heat-absorbing mounting plate 7. The bottom surface of the equipment box 1 is provided with a groove that matches the guide plate 10. The thermal expansion and contraction component 9 can control the guide plate 10 to move downward when heated. The heat dissipation fins 11 can dissipate heat from the heat-absorbing mounting plate 7, thereby dissipating heat from the detection linkage structure 2. The detection linkage structure 2 is detachably mounted on the heat-absorbing mounting plate 7. The top of the heat dissipation mechanism also includes a support plate 12 detachably mounted on one side of the support filter cover 6, several sets of cooling fans 13 rotatably mounted on the support plate 12 near the support filter cover 6, and a bidirectional drive motor 14 mounted on the other side of the support plate 12 and controlling the rotation of the cooling fans 13. The bidirectional drive motor 14 can dissipate heat from the detection linkage structure 2 and can exhaust hot air from the ventilation holes and the support filter cover 6 to the equipment box 1. The heat dissipation mechanism also includes a cleaning component 15 movably mounted on the outer wall of the equipment box 1 and a transmission assembly detachably connected to the cleaning component 15. The bidirectional drive motor 14 cleans the dust at the ventilation holes through the cleaning component 15. The output shaft at one end of the bidirectional drive motor 14 is detachably connected to the transmission assembly.

[0027] As one embodiment of the present invention, when the detection linkage structure 2 is activated, the radar sensor 3 is responsible for monitoring the speed of vehicles on the highway in real time and transmitting the vehicle speed data to the data processing module 4. The data processing module 4 receives the data transmitted by the radar sensor 3, processes and analyzes the data, and determines whether the vehicle speed is lower than the set value. When the vehicle speed is lower than the set value, the linkage execution module 5 can issue an alarm to remind the staff that there is a vehicle traveling at low speed, and the linkage execution module 5 will also remind the low-speed vehicle through the display screen.

[0028] When the radar sensor 3, data processing module 4, and linkage execution module 5 generate heat during operation, the heat-absorbing mounting plate 7 absorbs the heat and transfers it to the heat pipe 8 and heat dissipation fins 11. The heat pipe 8 transfers the heat to the thermal expansion and contraction component 9, causing the thermal expansion and contraction component 9 to expand due to heat. This causes the air guide plate 10 to move downwards, allowing external air to pass through the air guide plate 10 to dissipate heat from the heat pipe 8 and heat dissipation fins 11. When the temperature on the heat pipe 8 decreases, the thermal expansion and contraction component 9 contracts due to cold, causing the air guide plate 10 to move upwards. In addition, the bidirectional drive motor 14 is activated, driving the cooling fan 13 to rotate and dissipate heat from the radar sensor 3, data processing module 4, and linkage execution module 5. The bidirectional drive motor 14 drives the cleaning component 15 to move up and down through the transmission assembly to clean the dust at the ventilation holes, preventing external dust from clogging the ventilation openings.

[0029] In this embodiment, the thermal expansion and contraction component 9 includes a movable component 16 movably installed inside the heat conduction pipe 8 and an expansion component 17 connected to the movable component 16. The expansion component 17 can be made of rubber. When the temperature is 60 degrees, the volume of the rubber material can expand by about 2 times. One end of the expansion component 17 is connected to the heat conduction pipe 8. A support spring 18 connected to the heat conduction pipe 8 is sleeved on the movable component 16. The support spring 18 supports the movable component 16. The expansion component 17 can control the movement of the movable component 16 in the heat conduction pipe 8.

[0030] In this embodiment, the movable component 16 has an "I" shaped structure, both ends of the air guide plate 10 are inclined surfaces, the thermal expansion and contraction component 9 and the heat dissipation fins 11 are both provided on the supporting filter cover 6, and the upper end of the heat absorption mounting plate 7 is symmetrically provided with mounting rods 19 that are connected to the equipment box 1. The mounting rods 19 can increase the stability of the connection between the heat absorption mounting plate 7 and the equipment box 1.

[0031] Please refer to the accompanying drawings as one embodiment of the present invention. Figure 2 - Figure 4As shown, the heat-absorbing mounting plate 7 absorbs heat and transfers it to the heat-conducting pipe 8 and the heat dissipation fins 11. The heat-conducting pipe 8 transfers heat to the expansion member 17, causing the expansion member 17 to expand due to heat. This causes the moving member 16 to move downwards, which in turn causes the air guide plate 10 to move downwards, allowing external air to pass through the air guide plate 10 to dissipate heat from the heat-conducting pipe 8. When the heat-conducting pipe 8 and the expansion member 17 cool down and contract, the moving member 16 moves upwards, causing the air guide plate 10 to move upwards and thus reset.

[0032] In this embodiment, a transmission wheel 20 connected to the rotating shaft of the cooling fan 13 is rotatably mounted on the support plate 12. A rotating wheel 21 is provided on the output shaft of the other end of the bidirectional drive motor 14.

[0033] Please refer to the accompanying drawings as one embodiment of the present invention. Figure 2 and Figure 5 As shown, the bidirectional drive motor 14 is started, which drives the rotating wheel 21 to rotate. The rotating wheel 21 drives the transmission belt 22 to rotate, which in turn drives the transmission wheel 20 to rotate. The transmission wheel 20 drives the cooling fan 13 to rotate.

[0034] In this embodiment, the transmission assembly includes a first gear 24 mounted on one end of the output shaft of the bidirectional drive motor 14 and a second gear 25 rotatably mounted on the mounting component 23. The second gear 25 meshes with the first gear 24.

Several sets of rotating rods cooperate to make the first transmission rod 32, the second transmission rod 26, and the transmission block 27 rotatably connected. The bidirectional drive motor 14 controls the first transmission rod 32 to rotate through the first gear 24 and the second gear 25. The first transmission rod 32 can drive the cleaning component 15 to move up and down through the second transmission rod 26 and the transmission block 27.

[0035] Please refer to the accompanying drawings as one embodiment of the present invention. Figure 2 - Figure 6 As shown, the bidirectional drive motor 14 is started, which drives the first gear 24 to rotate. The first gear 24 drives the second gear 25 to rotate. The second gear 25 drives the first transmission rod 32 to rotate. The first transmission rod 32 drives the second transmission rod 26 to rotate. The second transmission rod 26 drives the transmission block 27 to move up and down. The transmission block 27 drives the cleaning component 15 to move up and down.

[0036] In this embodiment, ventilation holes are provided on both sides of the equipment box 1. Two sets of guide seats 28 and guide members 29 movably disposed inside the two sets of guide seats 28 are installed on the inner wall of the equipment box 1. One side of the transmission block 27 is fixedly connected to one side of the guide member 29. Two sets of reinforcing rods 30 are symmetrically installed on the cleaning member 15, and one end of the reinforcing rod 30 passes through the ventilation hole and is fixedly connected to the other side of the guide member 29. The guide seats 28 and the guide members 29 can guide the movement direction of the cleaning member 15.

[0037] Please refer to the accompanying drawings as one embodiment of the present invention. Figure 2 and Figure 6 As shown, when the bidirectional drive motor 14 is started, the transmission block 27 moves up and down through the first gear 24, the second gear 25, the first transmission rod 32 and the second transmission rod 26. The transmission block 27 drives the guide member 29 to move. The guide member 29 drives the cleaning member 15 to move up and down through the reinforcing rod 30, so that the cleaning member 15 cleans the dust at the ventilation hole.

[0038] In this embodiment, both ends of the guide member 29 are equipped with sliders 31, and the guide seat 28 is provided with a sliding groove that is slidably connected to the sliders 31. The guide seat 28 and the sliders 31 can improve the stability of the guide member 29 when it moves.

[0039] Please refer to the accompanying drawings as one embodiment of the present invention. Figure 6 As shown, the transmission block 27 drives the guide member 29 to move, so that the guide member 29 drives the slide member 31 to move in the slide groove.

[0040] The working principle of this utility model is as follows: When the detection linkage structure 2 is activated, the radar sensor 3 is responsible for monitoring the speed of vehicles on the highway in real time and transmitting the vehicle speed data to the data processing module 4. The data processing module 4 receives the data transmitted by the radar sensor 3, processes and analyzes the data, and determines whether the vehicle speed is lower than the set value. When the vehicle speed is lower than the set value, the linkage execution module 5 can issue an alarm to remind the staff that there is a vehicle traveling at low speed. The linkage execution module 5 also reminds the low-speed vehicle through the display screen.

[0041] When the radar sensor 3, data processing module 4, and linkage execution module 5 generate heat during operation, the heat-absorbing mounting plate 7 absorbs the heat and transfers it to the heat pipe 8 and heat dissipation fins 11. The heat pipe 8 transfers the heat to the thermal expansion and contraction component 9, causing the thermal expansion and contraction component 9 to expand due to heat. This causes the air guide plate 10 to move downward, allowing external air to pass through the air guide plate 10 to dissipate heat from the heat pipe 8 and heat dissipation fins 11. When the temperature on the heat pipe 8 decreases, the thermal expansion and contraction component 9 contracts due to cold, causing the air guide plate 10 to move upward. In addition, the bidirectional drive motor 14 is activated, driving the cooling fan 13 to rotate and dissipate heat from the radar sensor 3, data processing module 4, and linkage execution module 5. The bidirectional drive motor 14 drives the cleaning component 15 to move up and down through the transmission assembly to clean the dust at the ventilation holes, preventing external dust from clogging the ventilation openings.

[0042] When the radar sensor 3, data processing module 4, and linkage execution module 5 generate heat during operation, the heat-absorbing mounting plate 7 absorbs the heat and transfers it to the heat pipe 8 and heat dissipation fins 11. The heat pipe 8 transfers the heat to the thermal expansion and contraction component 9, causing the expansion component 17 to expand due to heat. This causes the moving component 16 to move downwards, and the moving component 16 causes the air guide plate 10 to move downwards, allowing external air to pass through the air guide plate 10 to dissipate heat from the heat pipe 8 and heat dissipation fins 11. When the temperature on the heat pipe 8 decreases, the thermal expansion and contraction component 9 contracts due to cold, causing the air guide plate 10 to move upwards and thus reset.

[0043] The bidirectional drive motor 14 is started, driving the rotating wheel 21 to rotate. The rotating wheel 21 drives the transmission belt 22 to rotate, which in turn drives the transmission wheel 20 to rotate. The transmission wheel 20 drives the cooling fan 13 to rotate, providing cooling for the radar sensor 3, data processing module 4, and linkage execution module 5. The bidirectional drive motor 14 is then started, driving the first gear 24 to rotate. The first gear 24 drives the second gear 25 to rotate, which in turn drives the first transmission rod 32 to rotate. The first transmission rod 32 drives the second transmission rod 26 to rotate, which in turn drives the transmission block 27 to move up and down. The transmission block 27 drives the guide member 29 to move, and the guide member 29, through the reinforcing rod 30, drives the cleaning member 15 to move up and down, allowing the cleaning member 15 to clean the dust at the ventilation holes and prevent external dust from clogging the ventilation openings.
