Abstract
Description
Technical Field
[0001] This invention relates to the field of outdoor protective equipment for agricultural sensors, specifically to a rainproof and heat dissipation device for an outdoor junction box for agricultural sensors. Background Technology
[0002] In agricultural production, sensors are widely used to monitor environmental information such as soil moisture, temperature, light intensity, and meteorological parameters, providing data support for precision agriculture. Sensors typically transmit the collected signals to a data processing system via a junction box. However, outdoor sensor junction boxes face numerous environmental challenges, with rain protection and heat dissipation being critical. Currently, some protective devices for outdoor sensor junction boxes exist on the market. Some devices only offer simple rain protection, such as using ordinary plastic shells for shielding. However, this design allows rainwater to easily seep in through gaps in the shell during heavy rain or prolonged rainfall, damaging the electronic components inside the junction box and affecting the normal operation of the sensor.
[0003] Regarding heat dissipation, some devices rely primarily on natural ventilation, but due to the complex outdoor environment, ventilation is often ineffective. Especially in hot weather or when sensors operate for extended periods, heat accumulates inside the junction box, leading to a decline in the performance of electronic components and shortening their lifespan. Some devices use fans for cooling, but fans are susceptible to dust and rain in outdoor environments, causing malfunctions, and the noise generated by the fans can also interfere with the surrounding environment. It is widely recognized in the industry that outdoor sensor junction boxes need to have excellent rainproof and heat dissipation performance to ensure that sensors can operate stably and reliably in various harsh environments.
[0004] Therefore, developing an outdoor junction box protection device that can effectively prevent rain and has good heat dissipation has become an urgent problem to be solved in the industry. Summary of the Invention
[0005] The technical problems to be solved by this invention are: (1) Insufficient rain protection: Existing simple plastic shell protective devices have poor sealing performance and cannot effectively block the intrusion of rainwater. In the case of heavy rainfall or long rainfall time, rainwater can easily enter the junction box from the splicing gaps of the shell, the inlet and outlet holes and other parts, causing short circuits and corrosion of electronic components, which seriously affects the service life and data accuracy of the sensor. (2) Poor heat dissipation: Natural ventilation heat dissipation is greatly affected by environmental factors. In the environment with low wind or poor air circulation, the heat dissipation effect is limited. Although fan heat dissipation can improve the heat dissipation efficiency to a certain extent, the fan itself is easily polluted by dust, rainwater and other pollutants, which leads to an increased failure rate. In addition, the noise generated by the fan operation will also cause certain interference to the agricultural ecological environment, which does not meet the requirements of modern agriculture for environmental protection and quiet working environment. (3) Single function: Most existing protective devices only focus on the single function of rain protection or heat dissipation, and lack comprehensive solutions. Some devices can achieve good rain protection but cannot effectively solve the heat dissipation problem; while some devices with good heat dissipation effect have obvious defects in rain protection. This single function design cannot meet the diverse needs of outdoor sensor junction boxes in complex environments.

[0020] Preferably, both the first and second water cooling heads are provided with a set of liquid inlet and liquid outlet on their sides. The discharge port of the micro water pump is connected to the liquid inlet of the first water cooling head through a water pipe. The liquid outlet of the first water cooling head is connected to the liquid inlet of the second water cooling head through a water pipe. The liquid outlet of the second water cooling head is connected to the liquid inlet of the micro water pump through a water pipe.
[0021] Preferably, the first water-cooling head is fixed inside the housing, and a bearing seat is provided on the side of the first water-cooling head, with a shaft body fixed inside the bearing seat.

[0022] Compared with the prior art, the advantages of this invention are: (1) Good rainproof performance: The rain canopy of this invention has a unique design with a guide channel on the front and a plug on the back.

(2) Highly efficient heat dissipation effect: The heat dissipation method combines water cooling and air cooling. The coolant is driven by a micro water pump to circulate between the first water cooling head and the second water cooling head. After the coolant absorbs the heat generated by the sensor junction box, it is transferred to the cooling fan through the heat pipe. The cooling fan blows out the heat, achieving highly efficient heat dissipation. Compared with traditional natural ventilation and single fan cooling, the heat dissipation effect of the present invention is better and is not affected by environmental factors, which can effectively solve the problem of poor heat dissipation effect in the prior art. (3) Comprehensive functions: The present invention integrates multiple functions such as rain protection, heat dissipation, fixing the sensor junction box and observing the sensor indicator light, providing comprehensive protection and convenient user experience for outdoor sensor junction boxes. Users only need to place the sensor junction box on the first water cooling head and rotate the second water cooling head to lock it in place, which can complete the fixing and achieve good heat dissipation and rain protection effects at the same time. In addition, through the first observation window and the second observation window, users can easily observe the working status of the sensor indicator light, which solves the problem of single function in the prior art.

[0035] Example 1
[0036] This embodiment provides a rainproof and heat dissipation device for an outdoor junction box for agricultural sensors. Specifically, it describes a specific implementation method regarding the composition and structural features of the components.
[0037] like Figure 1 As shown, the bracket 1 includes a crossbeam 103, with side frames 101 welded to both sides of the crossbeam 103. Self-tapping screw mounting positions 102 are welded to both sides of the side frames 101. The bracket 1 can be assembled and fixed on the plane by passing the self-tapping screw through the self-tapping screw mounting positions 102, providing a fixed support structure for the entire equipment, and used to support and fix components such as the box 2.
[0038] like Figure 2As shown, the box body 2 has a hinged door 201 on its side for easy opening and closing for internal operation; the top of the box body 2 has multiple first observation windows 203 at equal intervals for easy observation of the sensor indicator light status of the internal sensor junction box 7; the door 201 has multiple branch line holes 202 at equal intervals, and one side of the box body 2 has a main line hole 204 for the signal line of the sensor junction box 7 to extend out; the internal space of the box body 2 is divided into a first cavity 205 and a second cavity 206 by a partition. The first cavity 205 is used to place the sensor junction box 7 and to set the first water cooling head 501 and the second water cooling head 505. The second cavity 206 is equipped with a micro water pump 510 and a main control mechanism 6, providing installation space and layout for the various components inside the equipment.
[0039] like Figure 1 and Figure 9 As shown, the canopy 3 has a guide channel 301 on the front and a plug 302 on the back, and the back is coated with a diffuse reflection coating. When it rains, the canopy 3 is driven to rotate to an inclined state by the drive mechanism 4. The guide channel 301 allows the rainwater to fall smoothly and avoids the accumulation of rainwater. The plug 302 can be inserted into the socket 408 of the fixing base 407 for fixation. The diffuse reflection coating makes it easy to reflect the light of the sensor indicator light when it rains so that the status can be observed, and provides rain protection for the box 2.
[0040] like Figure 7 and Figure 8 As shown, the drive mechanism 4 includes a motor 401, with a gear commutator 402 rotatably connected to the motor shaft of the motor 401. First drive shafts 403 are rotatably connected to both sides of the gear commutator 402. The motor 401 is electrically connected to the main control mechanism 6 via a signal line, and its operation is controlled by the main control mechanism 6. One first drive shaft 403 is connected to a lead screw seat 404. A lead screw nut 406 is slidably mounted on the ball screw 405 of the lead screw seat 404. The top of the lead screw nut 406 is provided with a fixed seat 407 with a socket 408. A fixed shaft gear 409 is interference-fitted to the end of the other first drive shaft 403. The fixed shaft gear 409 is rotatably connected to a reduction gear 410, which is rotatably connected to the outer ring gear. On the planetary carrier 411, the gear planetary carrier 411 is fixed on the crossbeam 103. The reduction gear 410 is interference-fitted on a second transmission shaft 412. The shaft end of the second transmission shaft 412 is fixed with a support arm 413. A canopy 3 is welded to one side of the support arm 413. When it rains, the motor 401 works. The driving force is reduced and reversed in the initial stage by the gear commutator 402 and then distributed to the first transmission shafts 403 on both sides. One shaft drives the lead screw seat 404 to rotate the ball screw 405. The lead screw nut 406 moves outward along the shaft body. The other shaft drives the second transmission shaft 412 to rotate through the fixed shaft gear 409 and the reduction gear 410, so that the canopy 3 rotates around the second transmission shaft 412 to an inclined state, thereby realizing the driving and position adjustment of the canopy 3.
[0041] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the heat dissipation mechanism 5 includes a miniature water pump 510, which is electrically connected to the main control mechanism 6 via a signal line and is controlled by the main control mechanism 6. The miniature water pump 510 is connected to a first water cooling head 501, which is fixed inside the first cavity 205 of the housing 2. The first water cooling head 501 has a bearing seat 508 on its side, and a shaft 509 is fixed inside the bearing seat 508. The first water cooling head 501 is connected to a second water cooling head 505 via a water pipe 511. The second water cooling head 505 has a rotating seat 507 on its side that is adapted to the shaft 509. The second water cooling head 505 is rotatably connected to the first water cooling head 501 via the assembly of the rotating seat 507 and the shaft 509. Both the first and second water cooling heads 501 and 505 have a set of inlet ports 512 and outlet ports 513 on their sides. The discharge port of the micro water pump 510 is connected to the inlet port 512 of the first water cooling head 501 via a water pipe 511. The outlet port 513 of the first water cooling head 501 is connected to the inlet port 512 of the second water cooling head 505 via a water pipe 511. The outlet port 513 of the second water cooling head 505 is connected to the inlet port 512 of the second water cooling head 505 via a water pipe 511. 1. Connect the inlet of the micro water pump 510 to achieve coolant circulation; both the first water cooling head 501 and the second water cooling head 505 have copper sheets 503 on their surfaces. A threaded post 504 is provided on one side of the copper sheet 503 of the second water cooling head 505, and a matching limiting hole 502 is provided on one side of the copper sheet 503 of the first water cooling head 501. The second water cooling head 505 is fixedly connected to the first water cooling head 501 by assembling the threaded post 504 with the limiting hole 502, which can clamp the sensor junction box 7 from both sides; the second water cooling head 505 has a second observation window 506. 06 is located in the same vertical direction as the first observation window 203; both the first water-cooling head 501 and the second water-cooling head 505 are equipped with heat-conducting pipes 514 that are in contact with the water pipes 511 filled with coolant. One side of each heat-conducting pipe 514 is connected to a cooling fan 515. The coolant is driven by a micro water pump 510 to circulate between the first water-cooling head 501 and the second water-cooling head 505. After the coolant absorbs the heat generated by the sensor junction box 7, it transfers the heat to the cooling fan 515 through the heat-conducting pipes 514. The cooling fan 515 blows the heat out to achieve the heat dissipation function.
[0042] In addition, this device is equipped with a main control mechanism 6, which includes a PCB board with a CPU main control chip, a power supply, and auxiliary control circuits. The main control mechanism 6 is electrically connected to the motor 401 of the drive mechanism 4 and the miniature water pump 510 of the heat dissipation mechanism 5 via signal lines, and is used to control the operation of the drive mechanism 4 and the heat dissipation mechanism 5 to realize the automated operation and regulation of the equipment. The sensor junction box 7 is placed on the first water cooling head 501 of the first cavity 205 of the box body 2. The bottom surface contacts the copper sheet 503 of the first water cooling head 501. By rotating the second water cooling head 505, it is fastened on top, and the top surface contacts the copper sheet 503 of the second water cooling head 505. Tightening the threaded post 504 clamps the first water cooling head 501 and the second water cooling head 505 together and fixes them. It is used to collect environmental information such as soil moisture, temperature, light intensity, and meteorological parameters and transmit them to the data processing system via signal lines. The signal lines are extended from the branch line hole 202 and the main line hole 204, and the signal lines are equipped with waterproof sleeves.
[0043] Example 2
[0044] This embodiment provides a rainproof and heat dissipation device for an outdoor junction box for agricultural sensors. Specifically, it describes the usage method and functional principle of the device.
[0045] like Figures 1 to 10 As shown, bracket 1 serves as the fixed support structure for the equipment. Side frames 101 are welded to both sides of its crossbeam 103, and self-tapping screw mounting positions 102 are welded to both sides of the side frames 101. During equipment installation, self-tapping screws are passed through the self-tapping screw mounting positions 102 to securely mount bracket 1 to a wall or other flat surface, providing reliable support for the entire equipment and ensuring stable placement in outdoor environments. Open the hinged door 201 on the side of the housing 2 and place the sensor junction box 7 onto the first water-cooling head 501 inside the first cavity 205 of the housing 2. At this time, the bottom surface of the sensor junction box 7 is in close contact with the copper sheet 503 on the surface of the first water-cooling head 501, ensuring good heat conduction. Next, rotate the second water-cooling head 505 so that it rotates around the shaft 509 via a rotating seat 507 that matches the inner shaft 509 of the side shaft seat 508 of the first water-cooling head 501, and then latches onto the sensor junction box 7. At this point, the top surface of the sensor junction box 7 contacts the copper sheet 503 on the surface of the second water-cooling head 505. A threaded post 504 is provided on one side of the copper sheet 503 of the second water-cooling head 505, and a matching limiting hole 502 is provided on one side of the copper sheet 503 of the first water-cooling head 501. By screwing the threaded post 504 into the limiting hole 502, the first water-cooling head 501 and the second water-cooling head 505 clamp the sensor junction box 7 tightly, thus fixing the sensor junction box 7 and ensuring it does not shake during equipment operation, while also ensuring good heat dissipation contact.
[0046] The main control unit 6 is electrically connected to the miniature water pump 510 of the heat dissipation mechanism 5 via a signal line, controlling its operation. After the miniature water pump 510 starts, its discharge port delivers coolant through the water pipe 511 to the inlet port 512 of the first water cooling head 501, where the coolant enters the first water cooling head 501. After absorbing the heat generated by the sensor junction box 7, the coolant in the first water cooling head 501 flows out from its outlet port 513, and then through the water pipe 511 to the inlet port 512 of the second water cooling head 505, where it enters the second water cooling head 505. The coolant in the second water cooling head 505 continues to absorb heat, then flows out from its outlet port 513, and returns through the water pipe 511 to the inlet port of the miniature water pump 510, forming a complete coolant circulation system. Inside both the first water cooling head 501 and the second water cooling head 505, there are heat-conducting pipes 514 that contact the water pipes 511 that fill the coolant. The heat absorbed by the coolant during circulation is transferred to the cooling fan 515 through the heat pipe 514. The cooling fan 515 operates, blowing the heat out of the device, achieving efficient heat dissipation, effectively reducing the operating temperature of the sensor junction box 7, and ensuring its stable performance.
[0047] In rainless weather conditions, the canopy 3 stands upright above the housing 2, providing some shade for the equipment without obstructing observation of the sensor junction box 7. At this time, the drive mechanism 4 is stationary, and the motor 401 is not operating.
[0048] When rain is detected, the main control mechanism 6 electrically connects to the motor 401 of the drive mechanism 4 via a signal line to control its start-up. The motor shaft of motor 401 is rotatably connected to a gear commutator 402. The driving force of motor 401 is first transmitted to the gear commutator 402, and after initial deceleration and reversal, it is distributed to the first drive shafts 403 on both sides. One of the first drive shafts 403 is connected to a lead screw seat 404, transmitting the driving force to the lead screw seat 404, causing the ball screw 405 inside the lead screw seat 404 to rotate. The lead screw nut 406 on the ball screw 405 moves outward along the screw body, and the top of the lead screw nut 406 is provided with a fixing seat 407 with a insertion hole 408. Another first drive shaft 403 has a fixed-axis gear 409 with an interference fit at its end. The fixed-axis gear 409 is rotatably connected to a reduction gear 410, which is rotatably connected to a planetary gear carrier 411 on the outer ring. The planetary gear carrier 411 is fixed to the crossbeam 103. The second stage of speed reduction is achieved through the transmission of the fixed-axis gear 409 and the reduction gear 410. The reduction gear 410 is interference-fitted to a second drive shaft 412, driving the second drive shaft 412 to rotate. A support arm 413 is fixed to the end of the second drive shaft 412, and a canopy 3 is welded to one side of the support arm 413. The canopy 3, which was originally vertical, rotates synchronously around the second drive shaft 412 until the insertion rod 302 on its back is inserted into the insertion hole 408 of the fixing seat 407. At this time, the canopy 3 is tilted.
[0049] The tilted canopy 3 has a drainage channel 301 on its front, allowing rainwater to flow smoothly and preventing it from accumulating on the canopy 3. This effectively protects the housing 2 from rain and prevents rainwater from entering the housing 2 and damaging the sensor junction box 7. Meanwhile, the back of the canopy 3 is coated with a diffuse reflection coating, which helps reflect the light from the sensor indicator lights during rain, making it easier to observe the sensor status. Exposed components such as the motor 401, gear commutator 402, and lead screw seat 404 are all waterproof. The surfaces of the first drive shaft 403, fixed shaft gear 409, reduction gear 410, planetary gear carrier 411, second drive shaft 412, and support arm 413 are all treated with an anti-rust process, further improving the equipment's rain and rust resistance in rainy weather.
[0050] When it's not raining, with the canopy 3 upright, users can clearly observe the operating status colors of the indicator lights on the sensor junction box 7 through the second observation window 506 of the second water-cooling head 505 and the multiple first observation windows 203 equidistantly arranged on the top of the box 2, allowing them to promptly understand the sensor's operating status. When it rains, the light from the indicator lights on the sensor junction box 7 is transmitted upwards and projected through the diffuse reflection coating on the back of the canopy 3, directly displaying the top surface of the box 2. Even with the canopy 3 obstructing the view, users can still see the operating status colors of the indicator lights through the first observation windows 203, facilitating monitoring of sensor operation in rainy weather.
[0051] After collecting environmental information such as soil moisture, temperature, light intensity, and meteorological parameters, the sensor junction box 7 needs to transmit the data to the data processing system via signal lines. The signal lines from the sensor junction box 7 extend from multiple branch line holes 202 evenly spaced on the box door 201 and the main line hole 204 on one side of the box body 2. Furthermore, these signal lines are equipped with waterproof sleeves to further prevent rainwater from damaging the signal lines, ensuring the stability and reliability of data transmission.
[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
