Description

Technical Field

[0001] This invention relates to the field of temperature sensor technology, and in particular to a protective structure for a high-performance temperature sensor. Background Technology

[0002] An infrared temperature sensor is a device that uses infrared radiation to measure temperature. Its working principle is based on the characteristics of thermal radiation of objects, that is, all objects above absolute zero will radiate energy outward, and the intensity of the radiated energy is closely related to the surface temperature of the object. By receiving and analyzing this infrared radiation, the infrared temperature sensor can measure the temperature of an object non-contactly. It has advantages such as rapid response, wide measurement range, and simple operation. Since existing infrared temperature sensors are widely used in outdoor environments, their self-protection function is very important to ensure their normal use and long-term stability.

[0003] However, most existing protective structures for high-performance infrared temperature sensors only focus on the physical protection of the sensor's exterior, such as dustproofing, waterproofing, or impact resistance. They fail to adequately address the sensor's other needs under complex and variable outdoor weather conditions. Outdoors, infrared temperature sensors are susceptible to external electromagnetic interference, leading to abnormal readings and affecting their accuracy and reliability. In summer, due to extremely high outdoor temperatures and the fact that the infrared temperature sensor itself generates heat during operation, the internal temperature of the sensor will rise sharply without an effective heat dissipation mechanism. This not only affects measurement accuracy but may also accelerate the aging of internal components, reducing the sensor's lifespan and affecting its normal use. In winter, low temperatures can easily cause frost to form on the sensor lens. Frost formation can obstruct the lens, affecting the reception and conversion of infrared radiation, thus reducing the sensor's monitoring quality. This not only leads to inaccurate measurement data but may also prevent the capture of clear temperature images due to lens blur, severely impacting the sensor's practicality and reliability, resulting in poor usability. Summary of the Invention

[0004] The purpose of this invention is to address the problem that most existing protective structures for high-performance infrared temperature sensors only focus on physical protection of the sensor's exterior, which can easily lead to reduced monitoring quality and lifespan due to external temperature changes and electromagnetic interference. Therefore, this invention proposes a protective structure for high-performance temperature sensors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective structure for a high-performance temperature sensor, comprising a column, wherein a mounting bracket is detachably mounted on the outer wall of the column, and further comprising: The protective mechanism includes a housing, which is detachably mounted on the top of a mounting frame. Both ends of the housing are equipped with fixing frames. The outer walls of the two sets of fixing frames are respectively provided with openings and through-holes. Sensors are installed on the inner walls of the two sets of fixing frames. A cooling and shielding mechanism includes a water circulation component, a reinforcing mesh 1, a reinforcing mesh 2, and a reinforcing mesh 3. Reinforcing mesh 1, 2, and 3 are all cylindrical and installed on the inner wall of the outer casing. Reinforcing mesh 2 is located inside reinforcing mesh 1, reinforcing mesh 3 is located inside reinforcing mesh 2, and a sensor is located inside reinforcing mesh 3. Heat exchange tube 1, heat exchange tube 2, and heat exchange tube 3 are respectively installed on the outer walls of reinforcing mesh 1, 2, and 3, and all three are made of metal. The water circulation component is located on the outer wall of the outer casing and is used to provide circulating cooling water to heat exchange tube 1, heat exchange tube 2, and heat exchange tube 3. Both ends of heat exchange tube 1, heat exchange tube 2, and heat exchange tube 3 are connected to the water circulation component. The system includes a gas cooling mechanism and an air purification mechanism. The gas cooling mechanism is mounted on the outer shell to allow air circulation inside the shell. The air purification mechanism includes a screen, which is cylindrical and mounted on the inner wall of the outer shell. The screen covers a reinforcing mesh. The screen, reinforcing mesh one, and reinforcing mesh two are all externally connected to negative electrodes. The heat exchange tube one and heat exchange tube two are both externally connected to positive electrodes. A drainage assembly is provided at the bottom of the outer shell to drain water droplets from inside the shell.

[0006] Preferably, the lens of the sensor head is located at an opening on a set of fixed frames, and the power cable of the sensor tail passes through a through-hole on another set of fixed frames and is connected to an external power supply device.

[0007] Preferably, the water circulation assembly includes a water circuit assembly and a micro circulation pump. The water circuit assembly is mounted on the outer wall of the housing and is located at the tail of the sensor. The input and output ends of the water circuit assembly are respectively connected to an inlet pipe and a return pipe. The ends of the inlet pipe and the return pipe away from the water circuit assembly are respectively connected to the output and input ends of the micro circulation pump. Both ends of heat exchange tube one, heat exchange tube two, and heat exchange tube three penetrate the inner wall of the housing and are connected to the water circuit assembly. Cooling components are provided on the inlet pipe and the return pipe to reduce the temperature of the water flowing in the inlet pipe and the return pipe.

[0008] Preferably, the cooling component includes a spiral heat dissipation tube one and a spiral heat dissipation tube two, which are respectively installed on the outer walls of the water inlet pipe and the water return pipe. A throttling valve is installed on the water inlet pipe, and the throttling valve is located between the spiral heat dissipation tube one and the water circuit assembly.

[0009] Preferably, the gas cooling mechanism includes multiple sets of air inlets and multiple sets of ventilation fans. The multiple sets of air inlets are symmetrically arranged in pairs and are respectively installed through the bottom of the outer shell near the two sides. The multiple sets of ventilation fans are uniformly installed in an arc shape on the outer wall of the outer shell, and the outer walls of the multiple sets of ventilation fans are in contact with the outer wall of the fixing frame located at the sensor head. The space between the reinforcing mesh and the sensor is a duct. The multiple sets of ventilation fans are provided with air outlets through the connection between them and the outer shell, and the multiple sets of ventilation fans are connected to the duct through multiple sets of air outlets.

[0010] Preferably, it also includes a driving mechanism, which includes two sets of impellers. The two sets of impellers are symmetrically rotated and connected to the inner wall of the outer shell, and the positions of the two sets of impellers correspond to the positions of multiple sets of air inlets that are symmetrical in pairs. Multiple sets of bells are placed inside each set of impellers.

[0011] Preferably, the heat exchange tube one, the reinforcing mesh one, the heat exchange tube two, and the reinforcing mesh two are all coated with platinum catalyst metal.

[0012] Preferably, the drainage component includes a through-hole, which is disposed at the middle of the bottom end of the housing, and a connecting block is installed at the outward end of the through-hole, and a drainage pipe is fixedly installed at the bottom end of the connecting block.

[0013] Preferably, the connecting block is funnel-shaped, and a rubber hose is installed at the bottom end of the drain pipe.

[0014] Preferably, the system also includes a rainwater collection mechanism, which includes two sets of inlets and two sets of partitions. The two sets of inlets are symmetrically arranged through the top of the outer shell near both sides. The bottom ends of the two sets of partitions are symmetrically installed on the bottom wall of the inner shell, and the two sets of partitions are located on both sides of the screen. The two sets of partitions are located above multiple sets of air inlets, and the positions of the two sets of partitions correspond to the positions of the two sets of inlets. The space between each set of partitions and each set of inlets is a water storage chamber.

[0015] Compared with existing technologies, the advantages of this invention are: 1. This invention, through the coordinated operation of a protective mechanism, a cooling shielding mechanism, and a gas heat dissipation mechanism, can provide physical protection for the sensor while automatically adjusting the internal temperature environment of the housing based on external temperature changes and utilizing water circulation and air flow within the housing (i.e., implementing reasonable heat dissipation measures inside the housing according to the external temperature). This ensures that the sensor operates stably within a suitable operating temperature range, preventing performance degradation or damage caused by excessively high or low temperatures. Furthermore, the gas heat dissipation mechanism prevents frost formation on the sensor lens due to low external temperatures, effectively guaranteeing the sensor's monitoring quality and lifespan. Additionally, the innermost heat exchange tube and reinforcing mesh within the cooling shielding mechanism form a metal shielding layer around the sensor, preventing external electromagnetic interference and further ensuring the sensor's monitoring quality and lifespan.

[0016] 2. This invention, through the coordinated operation of a cooling shielding mechanism, a gas heat dissipation mechanism, and an air purification mechanism, utilizes the external negative electrodes of the screen, reinforcing mesh one, and reinforcing mesh two, as well as the external positive electrodes of heat exchange tube one and heat exchange tube two. This effectively removes moisture, dust, or other impurities from the air entering the casing during heat dissipation through air circulation inside the casing. Furthermore, the use of multiple sets of heat exchange tubes achieves cooling of the air. This not only improves the heat dissipation effect of air circulation on the sensor's working environment but also prevents dust particles and moisture from the outside air from adhering to the sensor surface. This not only ensures the cleanliness and operational stability of the sensor but also effectively extends its service life.

[0017] 3. This invention utilizes the combined action of a gas heat dissipation mechanism and an air purification mechanism. By leveraging the water droplets condensed on heat exchange tubes one and two, the electric field effect of part of the reinforcing mesh and part of the heat exchange tubes, and the platinum catalyst metal plating on the outside, it can effectively purify automobile exhaust when it enters the casing through the air inlet. During this process, harmful nitrogen oxides in the automobile exhaust are converted into nitrogen and oxygen. Part of the nitrogen is discharged through the ventilation fan, while the remainder further reacts to generate ammonia, which dissolves in the water droplets and is ultimately used for fertilizing roadside trees. This design not only effectively purifies harmful nitrogen oxides in automobile exhaust but also achieves resource reuse.

[0018] 4. This invention, through the cooperation of a gas cooling mechanism and a deterrent mechanism, allows for heat dissipation through air circulation inside the outer casing. The multiple air inlets in the gas cooling mechanism cause the two sets of impellers in the deterrent mechanism to rotate under the influence of external air. Since multiple bells are placed inside the impellers, they continuously rotate and emit sounds as the impellers rotate, thus frightening birds that perch near the protective device. This prevents birds from perching, nesting, damaging the wiring, or causing corrosion due to their droppings, effectively extending the device's lifespan and reducing the frequency of repairs by maintenance personnel.

[0019] 5. This invention, through the setting of a rainwater collection mechanism, can collect rainwater in rainy weather by using the inlet and water storage chamber. The rainwater in the storage chamber is continuously evaporated by the external sunlight shining on the outer shell or the residual heat generated by the sensor and then floats into heat exchange tube one and heat exchange tube two. This ensures that there is sufficient moisture on the outer wall of heat exchange tube one and heat exchange tube two, so that the vehicle exhaust purification process can proceed smoothly. If there is too much rainwater in the storage chamber, the excess rainwater will overflow from the inlet, thus avoiding the situation where the collected rainwater overflows the partition and damages the sensor.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Reference Figures 1 to 4 A protective structure for a high-performance temperature sensor includes a column 2, a mounting bracket 21 detachably mounted on the outer wall of the column 2, a protective mechanism 6 at the top of the mounting bracket 21, and a sensor 1 mounted on the protective mechanism 6. The protective mechanism 6 is used to protect the sensor 1, providing strength protection and protecting the sensor 1 from direct sunlight, hail, rain, etc. The protective mechanism 6 includes a housing 67, which is detachably mounted on the top of the mounting bracket 21. Both ends of the housing 67 are equipped with fixing frames. The outer walls of the two sets of fixing frames are respectively provided with openings and through-holes. The sensor 1 is fixedly mounted on the inner walls of the two sets of fixing frames, and the lens of the sensor 1 is located at the opening on one set of fixing frames. The power cord 11 at the tail of the sensor 1 passes through the through-hole on the other set of fixing frames and is connected to an external power supply device.

[0024] Reference Figures 1 to 5The outer casing 67 is equipped with a cooling and shielding mechanism to cool the sensor 1 and prevent it from being affected by external electromagnetic interference. The cooling and shielding mechanism includes a water circulation component, a first reinforcing mesh 612, a second reinforcing mesh 614, and a third reinforcing mesh 616. The first reinforcing mesh 612, the second reinforcing mesh 614, and the third reinforcing mesh 616 are all cylindrically mounted on the inner wall of the outer casing 67. The second reinforcing mesh 614 is located inside the first reinforcing mesh 612, and the third reinforcing mesh 616 is located inside the second reinforcing mesh 614. The sensor 1 is located within the... Inside the reinforced mesh 616, heat exchange tubes 611, 613, and 615 are respectively installed on the outer walls of reinforced meshes 612, 614, and 616. All three reinforced meshes are made of metal. A water circulation assembly is located on the outer wall of the outer shell 67 to provide circulating cooling water for heat exchange tubes 611, 613, and 615. Heat pipe 3 615 is connected to a water circulation assembly at both ends. The water circulation assembly includes a water circuit assembly 64 and a micro circulation pump 3. The water circuit assembly 64 is mounted on the outer wall of the housing 67 and is located at the tail of the sensor 1. The input and output ends of the water circuit assembly 64 are respectively connected to an inlet pipe 4 and a return pipe 5. The ends of the inlet pipe 4 and the return pipe 5 away from the water circuit assembly 64 are respectively connected to the output and input ends of the micro circulation pump 3. Heat exchanger tube 1 611, heat exchanger tube 2 613, and heat exchanger tube 3 61 Both ends of the water inlet pipe 4 and the water outlet pipe 5 are connected to the inner wall of the outer casing 67 and the water circuit assembly 64. Cooling components are provided on both the water inlet pipe 4 and the water outlet pipe 5 to reduce the temperature of the water flow in the water inlet pipe 4 and the water outlet pipe 5. The cooling components include a spiral heat dissipation tube 41 and a spiral heat dissipation tube 51. The spiral heat dissipation tube 41 and the spiral heat dissipation tube 51 are respectively installed on the outer wall of the water inlet pipe 4 and the water outlet pipe 5. A throttle valve 42 is installed on the water inlet pipe 4. The throttle valve 42 is located between the spiral heat dissipation tube 41 and the water circuit assembly 64.

[0025] When sensor 1 detects that the external temperature is higher than its preset temperature threshold, sensor 1 needs to dissipate heat. At this time, the micro-circulation pump 3 is activated. Due to the influence of natural processes such as transpiration from roadside trees, a low-temperature zone forms beneath the tree trunks. This low-temperature environment, combined with the coordinated operation of spiral heat dissipation pipe 41, spiral heat dissipation pipe 51, and throttle valve 42, can collectively reduce the temperature of the water flow in the inlet pipe 4 and the return pipe 5. Throttling valve 42 mainly controls the flow state of the water in the inlet pipe 4 by adjusting the flow rate and pressure, thereby indirectly affecting the water temperature. Specifically, throttle valve 42 can adjust the water flow as needed. The dynamic design ensures that the water flowing in the inlet pipe 4 can dissipate heat fully when passing through the spiral heat dissipation pipe 41, reaching a lower temperature. This ensures that the water flowing into the heat exchange pipes 611, 613, and 615 in the outer casing 67 is kept at a low temperature, effectively dissipating heat from the working environment of the sensor 1 (i.e., dissipating heat from inside the outer casing 67). At the same time, since the heat exchange pipe 615 and the reinforcing mesh 616, located on the innermost side of the outer casing 67, surround the sensor 1, and the reinforcing mesh 616 is made of metal, a metal shielding layer can be formed, thereby preventing the sensor 1 from experiencing abnormal readings due to external electromagnetic interference.

[0026] Reference Figures 2 to 6 A gas cooling mechanism is installed on the housing 67 to allow air circulation inside the housing 67, thereby dissipating heat from the sensor 1 inside the housing 67. The gas cooling mechanism includes multiple sets of air inlets 63 and multiple sets of ventilation fans 66. The multiple sets of air inlets 63 are symmetrically arranged in pairs and are respectively installed through the bottom of the housing 67 near the two sides. The multiple sets of ventilation fans 66 are evenly installed in an arc shape on the outer wall of the housing 67, and the outer walls of the multiple sets of ventilation fans 66 are in contact with the outer wall of the fixing frame located at the head of the sensor 1, strengthening the connection between the three-mesh 616 and the sensor 1. The space between them is a duct 68. Multiple sets of ventilation fans 66 are connected to the outer casing 67 and each has an air outlet 69. The multiple sets of ventilation fans 66 are connected to the duct 68 through multiple sets of air outlets 69. The outer casing 67 is equipped with a deterrent mechanism to deter birds from the outside. The deterrent mechanism includes two sets of impellers 617. The two sets of impellers 617 are symmetrically rotated and connected to the inner wall of the outer casing 67. The positions of the two sets of impellers 617 correspond to the positions of multiple sets of air inlets 63 that are symmetrical in pairs. Multiple sets of bells 618 are placed inside each set of impellers 617.

[0027] When sensor 1 detects that the outside temperature is higher than its preset temperature threshold, in addition to the start of the micro circulation pump 3, multiple sets of ventilation fans 66 will also be powered on and rotate to blow air outward, thereby creating a negative pressure inside the outer casing 67. Under the action of the internal negative pressure, outside air enters the interior of the outer casing 67 through multiple sets of air inlets 63. At this time, the two sets of impellers 617 rotate under the blowing of outside air. Since multiple sets of bells 618 are placed inside the impellers 617, the bells 618 will continuously flip and make sounds as the impellers 617 rotate, thereby startling the birds that are staying near the device, thus preventing the birds from staying or nesting and damaging the wiring on the device or producing droppings that corrode the device.

[0028] Reference Figures 1 to 6 An air purification mechanism is installed inside the outer casing 67 to purify the air entering the casing 67. The air purification mechanism includes a screen 610, which is cylindrical and installed on the inner wall of the outer casing 67. The screen 610 covers the reinforcing mesh 612. The screen 610, reinforcing mesh 612, and reinforcing mesh 614 are all externally connected to negative electrodes. The heat exchange tubes 611 and 613 are both externally connected to positive electrodes. All 614 are coated with platinum catalyst metal. The bottom of the outer shell 67 is provided with a drainage component for draining water droplets inside the outer shell 67. The drainage component includes a through-hole, which is located in the middle of the bottom of the outer shell 67. A connecting block is installed at the outward end of the through-hole. The connecting block is funnel-shaped, and a drain pipe 62 is fixedly installed through the bottom of the connecting block. The funnel-shaped design of the connecting block is to allow water droplets inside the outer shell 67 to enter the drain pipe 62 more smoothly. A rubber hose 61 is installed at the bottom of the drain pipe 62.

[0029] Because the outer casing of the reinforcing mesh 612 is equipped with a screen 610, and the screen 610, reinforcing mesh 612, and reinforcing mesh 614 are all externally connected with negative electrodes, while the heat exchange tubes 611 and 613 are externally connected with positive electrodes, the air entering the outer casing 67 and passing through the impeller 617 will first pass through the screen 610. The screen 610 will block larger particles of dust or other impurities in the air. At this time, smaller particles in the air pass through the screen 610 and continue to move forward, carrying negative charges due to the influence of the negative electrodes on the screen 610. The air that has been screened and carries negative charges will then pass through each set of heat exchange tubes and each set of reinforcing meshes in sequence. The smaller particles in the air that are negatively charged are repelled by the reinforcing mesh 612 and reinforcing mesh 614, which are externally connected with negative electrodes, and become positively charged. The heat exchange tubes 611 and 613 adsorb the heat. At the same time, the air is continuously cooled between the stacked heat exchange tubes 611 and 613, causing the corresponding water inside to be precipitated and attached to the tube walls of the heat exchange tubes 611 and 613. Finally, the cooled clean and dry air passes through the heat exchange tube 615 and the reinforcing mesh 616 and is further cooled before entering the air duct 68. The heat generated by the sensor 1 is carried away by the air in the air duct 68 (the air refers to the aforementioned clean and dry air) and blown out by the ventilation fan 66 through the air outlet 69. This effectively achieves further heat dissipation of the working environment of the sensor 1, and at the same time, it can prevent dust particles and moisture in the outside air from adhering to the surface of the sensor 1.

[0030] When sensor 1 detects that the outside temperature is lower than its preset temperature threshold, the ventilation fan 66 starts rotating intermittently (at this time, the micro circulation pump 3 is in the off state). The lower the outside temperature, the longer the intermittent time of the ventilation fan 66. This ensures heat dissipation of the working environment of sensor 1 in summer and other high-temperature conditions, and maintains heat dissipation of the working environment of sensor 1 in winter and other low-temperature conditions. At the same time, it uses the heat generated by sensor 1 to keep itself warm, preventing sensor 1 from freezing due to low temperature. In addition, since the air blown out by the ventilation fan 66 is hot air after heat dissipation, its temperature is higher than the outside temperature. Therefore, in winter and other seasons prone to frost, this design can effectively prevent frost from forming on the lens of sensor 1, thus effectively ensuring the monitoring quality of sensor 1.

[0031] Furthermore, as the air entering the outer casing 67 continuously cools between the stacked heat exchange tubes 611 and 613, and the water inside condenses and adheres to the tube walls of the heat exchange tubes 611 and 613, some water droplets condensed on the heat exchange tubes 611 and 613 will slide down the tube walls and, after passing through the reinforcing mesh 612 and 614 located below the sensor 1, will finally fall into the drain pipe 62. Other water droplets will be electrolyzed by the heat exchange tubes 611 and 613 with positive electrodes and the reinforcing mesh 612 and 614 with negative electrodes, producing oxygen and hydrogen. The electrolyzed oxygen and hydrogen will diffuse within the outer casing 67. Due to the setting of the column 2... Located next to roadside trees on the outer side of the road (i.e., the entire device is set up next to roadside trees on the outer side of the road), the device will be surrounded by a large number of cars. As a result, the air entering the outer casing 67 from the air inlet 63 will contain a large amount of car exhaust gas (car exhaust gas mainly contains nitric oxide and nitrogen dioxide). The large amount of nitrogen oxides in car exhaust gas is extremely harmful to the environment and people. When the air containing a large amount of car exhaust gas enters the outer casing 67, the unstable nitrogen oxides (nitric oxide) in the car exhaust gas are oxidized into more stable nitrogen oxides (nitric oxide) by the oxygen in the outer casing 67 and the platinum catalyst metal plated on the heat exchange tube 611, reinforcing mesh 612, heat exchange tube 613, and reinforcing mesh 614.

[0032] Meanwhile, the aforementioned nitrogen oxides (nitrogen dioxide) react with hydrogen under the catalysis of platinum catalyst to produce nitrogen and oxygen. Some of the nitrogen is discharged by the ventilation fan 66, while the remaining nitrogen will continue to react with hydrogen to produce ammonia, which dissolves into the water droplets that will fall into the drain pipe 62. Since a rubber hose 61 is installed at the bottom of the drain pipe 62, the ammonia water in the drain pipe 62 can be guided to the soil at the bottom of the roadside trees by the rubber hose 61. This design not only helps the roadside trees absorb and utilize the nitrogen element in the ammonia water, thereby reducing the use of nitrogen fertilizer, but also achieves effective purification and reuse of harmful nitrogen oxides in automobile exhaust.

[0033] Reference Figure 2 and Figure 6 The outer shell 67 is equipped with a rainwater collection mechanism for collecting rainwater from the outside. The rainwater collection mechanism includes two sets of inlets 65 and two sets of partitions 620. The two sets of inlets 65 are symmetrically arranged through the top of the outer shell 67 near the two sides. The bottom ends of the two sets of partitions 620 are symmetrically installed on the inner bottom wall of the outer shell 67, and the two sets of partitions 620 are located on both sides of the screen 610. The two sets of partitions 620 are located above multiple sets of air inlets 63, and the positions of the two sets of partitions 620 correspond to the positions of the two sets of inlets 65. The space between each set of partitions 620 and each set of inlets 65 is a water storage chamber 619.

[0034] When encountering rainy weather, rainwater will enter the water storage chamber 619 through the inlet 65. Through the external sunlight shining on the outer shell 67 or the residual heat generated by the sensor 1 heating the baffle 620, the water in the water storage chamber 619 can continuously evaporate and drift into the heat exchange tube 1 611 and heat exchange tube 2 613, thereby ensuring sufficient moisture on the outer walls of the heat exchange tube 1 611 and heat exchange tube 2 613. If there is too much rainwater in the water storage chamber 619, the excess rainwater will overflow from the inlet 65, thereby preventing the rainwater from overflowing the baffle 620 and damaging the sensor 1.

[0035] This invention is applied to the protection of infrared temperature sensors used for urban road temperature monitoring. The sensor 1 is installed in the protective mechanism 6. When the sensor 1 is installed, it is usually preset with a specific temperature threshold by the operator. The outer shell 67 in the protective mechanism 6 provides strong protection for the sensor 1 while protecting it from direct sunlight, hail, rain, etc. The sensor 1's head lens and tail power cable 11 protrude from the outer shell 67 through openings and ports on two sets of fixing frames. After adjusting the angle of the outer shell 67 according to requirements... The sensor 1 (after adjusting its angle) is detachably mounted on the mounting bracket 21, and the mounting bracket 21 is detachably mounted on the column 2. The column 2 is located next to the roadside trees on the outer side of the road. The micro circulation pump 3 is installed on the roadside trees. The micro circulation pump 3 provides power to the water circuit inside the housing 67, and the water circuit assembly 64 connects the heat exchange tube 1 611, heat exchange tube 2 613, and heat exchange tube 3 615 to the inlet pipe 4 and the return pipe 5, thereby ensuring the circulating water supply to the heat exchange tube 1 611, heat exchange tube 2 613, and heat exchange tube 3 615. Spiral heat dissipation pipe 41 and spiral heat dissipation pipe 51 are respectively installed on the outer walls of pipe 4 and return pipe 5. When sensor 1 detects that the external temperature is higher than its preset temperature threshold, sensor 1 needs to dissipate heat. At this time, micro circulation pump 3 is started. Due to the influence of natural processes such as transpiration of roadside trees, a low-temperature area will form under the trunk. This low-temperature environment, together with the coordinated work of spiral heat dissipation pipe 41, spiral heat dissipation pipe 51 and throttle valve 42, can reduce the temperature of the water flow in inlet pipe 4 and return pipe 5, thus saving water temperature. The flow valve 42 mainly controls the flow state of the water in the inlet pipe 4 by adjusting the flow rate and pressure, thereby indirectly affecting the water temperature. Specifically, the flow valve 42 can adjust the dynamics of the water flow as needed to ensure that the water in the inlet pipe 4 can dissipate heat fully when passing through the spiral heat dissipation tube 41, reaching a lower temperature. This ensures that the temperature of the water entering the heat exchange tubes 611, 613, and 615 in the outer casing 67 is low, thus effectively achieving heat dissipation of the working environment of the sensor 1 (i.e., heat dissipation inside the outer casing 67).

[0036] Furthermore, when sensor 1 detects that the outside temperature is higher than its preset temperature threshold, multiple sets of ventilation fans 66 are energized and rotate, blowing air outwards, thereby creating negative pressure inside the outer casing 67. Under the action of the internal negative pressure, outside air enters the interior of the outer casing 67 through multiple sets of air inlets 63. At this time, the two sets of impellers 617 rotate under the blowing of outside air. Since multiple sets of bells 618 are placed inside the impellers 617, the bells 618 will continuously flip and make sounds as the impellers 617 rotate, thereby scaring away birds that are staying near the device, preventing birds from staying or nesting and damaging the wiring on the device or producing droppings that corrode the device, thus effectively extending the life of the device and reducing the number of repairs required by maintenance personnel.

[0037] Because the reinforcing mesh 612 is covered by a screen 610, and the screen 610, reinforcing mesh 612, and reinforcing mesh 614 are all externally connected to negative electrodes, while heat exchange tubes 611 and 613 are externally connected to positive electrodes, the air entering the outer shell 67 and passing through the impeller 617 will first pass through the screen 610. The screen 610 will block larger particles of dust or other impurities in the air. At this time, smaller particles in the air pass through the screen 610 and continue to move forward, carrying negative charges due to the influence of the negative electrodes on the screen 610. The filtered air carrying negative charges will then pass through each set of heat exchange tubes and each set of reinforcing meshes in sequence. The smaller particles in the air carrying negative charges are repelled by the reinforcing mesh 612 and 614 with externally connected negative electrodes and adsorbed by the heat exchange tubes 611 and 613 with externally connected positive electrodes. At the same time, the air passes through the stacked heat exchange tubes. The heat exchange tube 611 and the heat exchange tube 613 are continuously cooled, causing the corresponding water inside to be precipitated and adhere to the tube walls of the heat exchange tube 611 and the heat exchange tube 613. Finally, the clean and dry air that has been cooled down passes through the heat exchange tube 615 and the reinforcing mesh 616 and is further cooled down, and then enters the air duct 68. The heat generated by the sensor 1 is carried away by the air in the air duct 68 (this air refers to the aforementioned clean and dry air) and blown out by the ventilation fan 66 through the air outlet 69. This effectively achieves further heat dissipation of the working environment of the sensor 1, that is, effectively improves the heat dissipation effect of the working environment of the sensor 1. At the same time, while improving the heat dissipation effect, it effectively prevents dust particles and moisture in the outside air from adhering to the surface of the sensor 1. This not only ensures the cleanliness and operational stability of the sensor 1, but also effectively extends its service life.

[0038] When sensor 1 detects that the ambient temperature is lower than its preset temperature threshold, the ventilation fan 66 starts rotating intermittently (at this time, the micro circulation pump 3 is in the off state). The lower the ambient temperature, the longer the intermittent time of the ventilation fan 66. This ensures heat dissipation of the sensor 1's working environment in hot summer and cold winter, while maintaining heat dissipation of the sensor 1's working environment and using the heat generated by the sensor 1 to keep itself warm, preventing the sensor 1 from freezing due to low temperature. In addition, since the air blown out by the ventilation fan 66 is hot air after heat dissipation, its temperature is higher than the ambient temperature. Therefore, in winter and other seasons prone to frost, this design can effectively prevent frost from forming on the lens of the sensor 1, thus effectively ensuring the monitoring quality of the sensor 1. At the same time, since the heat exchange tube 3 615 and the reinforcing mesh 3 616 located on the innermost side of the outer shell 67 surround the sensor 1, and the reinforcing mesh 3 616 is made of metal, a metal shielding layer can be formed, thereby preventing the sensor 1 from having abnormal readings due to external electromagnetic interference. This effectively ensures the accuracy and reliability of its monitoring data and extends the service life of the sensor 1.

[0039] As the air entering the outer casing 67 continuously cools between the stacked heat exchange tubes 611 and 613, and the water inside condenses and adheres to the walls of the heat exchange tubes 611 and 613, some water droplets condensed on the heat exchange tubes 611 and 613 will slide down the tube walls and, after passing through the reinforcing mesh 612 and 614 located below the sensor 1, will finally fall into the drain pipe 62. Other water droplets will be electrolyzed by the heat exchange tubes 611 and 613 (with positive electrodes) and the reinforcing mesh 612 and 614 (with negative electrodes), producing oxygen and hydrogen. The electrolyzed oxygen and hydrogen will diffuse within the outer casing 67. Since the pillar 2 is located next to the roadside trees on the outer side of the road... (That is, the entire device is set up next to the roadside trees on the outside of the road), so that a large number of cars will pass by the device. As a result, the air entering the outer casing 67 from the air inlet 63 will contain a large amount of car exhaust gas (car exhaust gas mainly contains nitric oxide and nitrogen dioxide). The large amount of nitrogen oxides contained in car exhaust gas is extremely harmful to the environment and people. When the air containing a large amount of car exhaust gas enters the outer casing 67, the unstable nitrogen oxides (nitric oxide) in the car exhaust gas are oxidized into more stable nitrogen oxides (nitric oxide) by the oxygen in the outer casing 67 and the platinum catalyst metal (other catalyst metals or alloys can also be selected) plated on the heat exchange tube 1 611, reinforcing mesh 1 612, heat exchange tube 2 613, and reinforcing mesh 2 614.

[0040] Meanwhile, the aforementioned nitrogen oxides (nitrogen dioxide) will react with hydrogen under the catalysis of platinum catalyst to produce nitrogen and oxygen (nitrogen is one of the most abundant gases in the Earth's atmosphere, chemically stable, and harmless to humans and the environment). Some of the nitrogen is discharged by the ventilation fan 66, while the remaining nitrogen will continue to react with hydrogen to produce ammonia (ammonia is easily soluble in water) and dissolve into the water droplets that will fall into the drain pipe 62. Since a rubber hose 61 is installed at the bottom of the drain pipe 62, the ammonia water in the drain pipe 62 can be guided to the soil at the bottom of the roadside trees by the rubber hose 61. This design not only helps the roadside trees absorb and utilize the nitrogen element in the ammonia water, thereby reducing the use of nitrogen fertilizer, but also achieves effective purification and reuse of harmful nitrogen oxides in automobile exhaust.

[0041] When encountering rainy weather, rainwater will enter the water storage chamber 619 through the inlet 65. Through the external sunlight shining on the outer shell 67 or the residual heat generated by the sensor 1 heating the baffle 620, the water in the water storage chamber 619 can continuously evaporate and drift into the heat exchange tube 1 611 and heat exchange tube 2 613, thereby ensuring sufficient moisture on the outer walls of the heat exchange tube 1 611 and heat exchange tube 2 613 so that the above reactions can proceed normally. If there is too much rainwater in the water storage chamber 619, the excess rainwater will overflow from the inlet 65, thereby preventing the rainwater from overflowing the baffle 620 and damaging the sensor 1.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
