Description

Technical Field

[0001] This invention relates to the field of electrical control cabinet technology, and in particular to an intelligent modular wiring base for control cabinets. Background Technology

[0002] In electrical control systems, the wiring inside the control cabinet is complex and numerous. Traditional wiring methods often suffer from problems such as messy wiring, difficult maintenance, and low reliability. The base, on the other hand, is a wiring mechanism that enables intelligent control, modular installation, and easy maintenance and management.

[0003] In order to allow air to alternate between the inside and outside and to prevent the internal temperature from getting too high, existing bases usually have heat dissipation vents on the side walls. In order to prevent external impurities from entering through the heat dissipation vents, blades are installed inside the heat dissipation vents. However, since the blades are fixed and cannot rotate, the size of the channel available for gas flow is constant. The blades cannot rotate according to the temperature changes inside the base, thereby changing the size of the channel available for gas flow. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: the blades in the existing base are fixed and cannot rotate, thus the size of the gas flow channel is constant, and the blades cannot rotate according to the temperature changes inside the base to change the size of the gas flow channel. Therefore, this invention proposes an intelligent modular wiring base for control cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A control cabinet intelligent modular wiring base includes a base body. Multiple terminals are located at the bottom of the base body. A heat dissipation vent is provided on the side wall of the base body. A rotating shaft is symmetrically and horizontally mounted within the heat dissipation vent. Opening and closing blades are fixedly sleeved on the rotating shaft. A longitudinally distributed positive temperature coefficient thermistor and electromagnet are fixedly mounted on the inner wall of the base body. The positive temperature coefficient thermistor and electromagnet are electrically connected via wires. A first spring rod is fixedly mounted at the bottom of the base body. A magnetic block is fixedly mounted at the top of the first spring rod, corresponding to the position of the electromagnet. A rectangular groove is provided on the inner wall of the base body. One end of the rotating shaft passes through the rectangular groove and is fixedly sleeved with a gear. The end of the first spring rod away from the bottom wall of the base body is fixedly mounted with a rack rod that meshes with multiple gears via an L-shaped connecting rod.

[0007] A round rod is fixedly installed on the surface of the gear located below. A semi-annular groove is formed in the wall of the rectangular groove. The end of the round rod away from the gear is slidably disposed in the semi-annular groove. A water collection cavity is formed in the side wall of the seat. A water inlet communicating with the water collection cavity is formed in the side wall of the seat. A water guide pipe covering the water inlet is fixedly installed in the side wall of the seat. A sliding opening communicating with the water collection cavity is formed in the wall of the semi-annular groove. A limiting component for limiting the movement distance of the sliding rod is slidably disposed in the sliding opening. A floating component is provided in the water collection cavity for releasing the limiting component from restricting the sliding rod in rainy weather.

[0008] As a preferred embodiment, the limiting component includes a slide rod, a second spring rod, and a limiting block that are horizontally slidably disposed within a sliding opening. One end of the slide rod, located within a semi-annular groove, has a rotating opening. A first rotating rod is horizontally rotatably mounted within the rotating opening. The limiting block is fixedly sleeved on the first rotating rod. A first torsion spring is sleeved on the first rotating rod, with both ends of the first torsion spring fixedly connected to the limiting block and the slide rod, respectively. A semi-annular rotation-limiting opening is formed in the wall of the rotating opening with the first rotating rod as its center. A first insert rod is fixedly mounted on the surface of the limiting block, with its end passing through the rotation-limiting opening. A placement block is fixedly mounted on the upper surface of the slide rod, located within the water collection cavity. Both ends of the second spring rod are fixedly connected to the surface of the placement block and the wall of the water collection cavity, respectively.

[0009] As a preferred embodiment, the floating assembly includes a float that can float on the surface of rainwater, a pull rope, and an I-shaped guide wheel. The float is vertically slidably disposed in the water collection cavity. The two ends of the pull rope are respectively fixedly connected to the lower surface of the float and the end of the slide rod located in the water collection cavity. A fixed shaft is rotatably mounted on the wall of the water collection cavity. The I-shaped guide wheel is rotatably mounted on one end of the fixed shaft, and the pull rope passes through the I-shaped guide wheel.

[0010] As a preferred embodiment, the side wall of the base has an inverted U-shaped opening, and a cooling component is fixedly installed inside the opening. The cooling component is used to reduce the temperature of the positive temperature coefficient thermistor by using rainwater during rainy weather.

[0011] As a preferred embodiment, the cooling component includes a cooling plate that is sealed and fixedly installed inside the opening. The portion of the cooling plate inside the base covers the top and sides of the positive temperature coefficient thermistor, and a water inlet groove is provided on the surface outside the base.

[0012] As a preferred embodiment, both the bottom of the water inlet tank and the bottom of the water collection cavity are provided with water outlet holes that communicate with the outside, and the water outlet holes are used for rainwater to flow out.

[0013] As a preferred embodiment, an L-shaped locking rod is fixedly installed at the top of the rack rod, and mounting blocks are symmetrically fixedly installed on the walls of the rectangular groove. A second rotating rod is horizontally rotatably installed between the two mounting blocks. A rotating block for locking the locking rod is fixedly sleeved on the second rotating rod, and a second torsion spring is sleeved on the second rotating rod. The two ends of the second torsion spring are fixedly connected to the mounting block and the rotating block, respectively. An opening communicating with the through-hole and the rectangular groove is opened in the inner wall of the seat. A semi-annular rotation limiting groove is opened on the side wall of the rotating block with the second rotating rod as the center. An insertion port is opened on the surface of the mounting block near the rotation limiting groove. A second insertion rod is slidably inserted into the insertion port. The end of the second insertion rod corresponds to the position of the rotation limiting groove. The second insertion rod is controlled to move laterally by a pressing component.

[0014] As a preferred embodiment, the pressure-reducing assembly includes an inclined plate fixedly installed at one end of the second insert rod, an I-shaped slider, and a float that can float on the surface of the rainwater. The inclined plate has an oblique opening on its surface, and the I-shaped slider is slidably disposed within the oblique opening. The cooling plate has a vertically opening on its side wall that communicates with the water inlet trough. A straight rod is vertically slidably disposed within the side opening. One end of the straight rod located within the water inlet trough is fixedly connected to the float, and the other end located outside the water inlet trough is fixedly connected to the surface of the I-shaped slider. A sealing component is provided on the straight rod to seal the side opening. The sealing component includes a sealing plate fixedly sleeved on the straight rod. Both the upper and lower walls of the side opening have vertically opening sealing grooves, and the two ends of the sealing plate are respectively slidably inserted into the two sealing grooves.

[0015] As a preferred embodiment, the surface of the opening and closing blades is provided with vents, the top of the heat dissipation vent is provided with an air inlet that communicates with the body, and the bottom of the heat dissipation vent is provided with an air outlet that communicates with the outside. The longitudinal section of the air inlet and the air outlet are both L-shaped. The bottom surface of the bottom opening of the air outlet is inclined with the inside higher than the outside. A water baffle is fixedly installed on one side of the body. The water baffle is located above the bottom opening of the air outlet and is inclined. The air inlet, the air outlet and the two vents form a communication channel for gas flow.

[0016] As a preferred embodiment, a fixing block is fixedly installed inside the bottom opening of the air outlet. Multiple mounting holes are equidistantly opened on the surface of the fixing block. A miniature blower is installed inside each mounting hole. A contact block is fixedly installed on the surface of the rotating shaft located below. A touch switch located on the rotation path of the contact block is fixedly installed at the bottom of the rectangular groove. The touch switch is electrically connected to multiple miniature blowers.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Through the cooperation of a positive temperature coefficient thermistor, electromagnet, magnetic block, first spring rod, gear, and rack, multiple opening and closing blades will rotate when the internal temperature of the base rises, thereby increasing the size of the gas flow channel. When the internal temperature of the base decreases, the size of the gas flow channel will decrease. The opening and closing blades can rotate according to the temperature change inside the base, thereby changing the size of the gas flow channel. The size of the gas flow channel is no longer constant, which improves practicality.

[0019] 2. When it rains, the cooling plate will collect the rainwater from the outside, thereby cooling the temperature of the positive temperature coefficient thermistor. This will cause multiple opening and closing blades to rotate to a vertical position, thereby closing the heat dissipation vents and preventing rainwater from entering the base through the vents.

[0020] 3. When the collected rainwater cools the temperature of the positive temperature coefficient thermistor and the multiple opening and closing blades rotate to a vertical position, the position of the multiple opening and closing blades will be locked to prevent the temperature inside the base from increasing due to the closure of the heat dissipation vent, which would cause the multiple vertical opening and closing blades to rotate and open the heat dissipation vent again.

[0021] 4. The floating component will be affected by the buoyancy of the collected rainwater, which will release the restriction component on the slide bar. This will cause multiple opening and closing blades to rotate to a vertical position when the temperature inside the base is high, and close the heat dissipation vents. This will prevent the multiple opening and closing blades from being unable to rotate to a vertical position and close the heat dissipation vents when the temperature of the collected rainwater is too high to reduce the temperature of the positive temperature coefficient thermistor to the required temperature.

[0022] 5. By opening vents on the surface of the opening and closing blades, and combining them with the air inlet at the top and the air outlet at the bottom of the heat dissipation vent, a dedicated gas flow channel is constructed. Even when the opening and closing blades are in a vertical waterproof state, the hot air inside the base can still enter the vent through the air inlet and then be discharged to the outside through the air outlet. This solves the core contradiction of "waterproofing in rainy weather and internal heat dissipation cannot be taken into account at the same time", ensuring that the base can maintain a stable internal thermal environment in rainy weather and preventing electrical components from being damaged by high temperature.

[0023] 6. When the miniature blower is working, it can create negative pressure at the air outlet, which accelerates the flow speed of hot air inside the base in the circulation channel, significantly improving the efficiency of hot air discharge. Especially for scenarios where heat is easily accumulated inside the base in rainy weather, it can quickly reduce the internal temperature and avoid component performance degradation or failure due to untimely heat dissipation, further enhancing the heat dissipation effect in rainy weather. At the same time, the miniature blower can be started and stopped on demand without manual intervention.

[0024] 7. After the miniature blower is started, it produces a suction effect, creating a continuous negative pressure environment inside the air outlet. Outside air will be guided to the outside of the air outlet by the "airflow attraction" formed by this negative pressure rather than the inside. At the same time, the high-speed airflow during the suction process can generate a "blocking force" against rainwater trying to enter the air outlet, thus strengthening the waterproof capability of the air outlet.

[0025] 8. After the miniature blower accelerates the airflow, it will form a "dynamic airflow barrier" between the opening and closing blades and in the gaps between the blades and the heat dissipation vents. The kinetic energy of the high-speed airflow can directly block raindrops and fog from passing through the gaps. At the same time, the local air pressure difference formed by the airflow in the channel will "push" the rainwater away from the gap area, effectively preventing rainwater from entering the interior of the seat through unexpected paths.

Detailed Implementation

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0049] Reference Figures 1-21 A control cabinet intelligent modular wiring base includes a base body 1. Multiple terminals 2 are located at the bottom of the base body 1. A heat dissipation vent 3 is opened on the side wall of the base body 1. A rotating shaft 4 is symmetrically and horizontally mounted within the heat dissipation vent 3. Opening and closing blades 5 are fixedly sleeved on the rotating shaft 4. Longitudinally distributed positive temperature coefficient thermistors 6 and electromagnets 7 are fixedly installed on the inner wall of the base body 1. The positive temperature coefficient thermistors 6 and electromagnets 7 are electrically connected by wires. A first spring rod 8 is fixedly installed at the bottom of the base body 1. A magnetic block 9 is fixedly installed at the top of the first spring rod 8, and the magnetic block 9 corresponds to the position of the electromagnet 7. A rectangular groove is opened on the inner wall of the base body 1. One end of the rotating shaft 4 passes through the rectangular groove and is fixedly sleeved with a gear 10. The end of the first spring rod 8 away from the bottom wall of the base body 1 is fixedly mounted with a rack rod 12 that meshes with multiple gears 10 via an L-shaped connecting rod 11.

[0050] The positive temperature coefficient thermistor 6 has a higher resistance value at higher temperatures, resulting in a smaller current that can pass through, a weaker magnetism of the electromagnet 7, and a smaller magnetic attraction force on the magnetic block 9. Conversely, the lower the temperature, the lower the resistance, resulting in a larger current that can pass through, a stronger magnetism of the electromagnet 7, and a greater magnetic attraction force on the magnetic block 9.

[0051] When the temperature inside the base 1 is high, the magnetic attraction force on the magnetic block 9 is small, the distance between the magnetic block 9 and the electromagnet 7 is long, and the extension distance of the first spring rod 8 is short. At this time, all the opening and closing blades 5 are in a horizontal state, and the channel size for gas flow between the multiple opening and closing blades 5 is the largest. When the temperature inside the base 1 is low, the magnetic attraction force on the magnetic block 9 is large, the distance between the magnetic block 9 and the electromagnet 7 is short, and the extension distance of the first spring rod 8 is long. When the magnetic block 9 moves vertically, the rack rod 12 also moves together, so that the multiple opening and closing blades 5 are in a horizontal state. The gear 10, which is meshed with the rack and pinion 12, will drive the two rotating shafts 4 and the two opening and closing blades 5 to rotate together. The size of the gas flow channel between the two opening and closing blades 5 will gradually decrease. That is, the two opening and closing blades 5 can rotate according to the temperature change inside the seat 1. The position of the opening and closing blades 5 is no longer constant. When the temperature inside the seat 1 is high, the size of the gas flow channel between the two opening and closing blades 5 will increase, and when the temperature inside the seat 1 is low, the size of the gas flow channel between the two opening and closing blades 5 will decrease. This makes it highly practical.

[0052] A round rod 13 is fixedly mounted on the surface of the gear 10 located below. A semi-annular groove 14 is formed in the wall of the rectangular groove. The end of the round rod 13 away from the gear 10 is slidably disposed in the semi-annular groove 14. A water collection cavity 15 is formed in the side wall of the seat body 1. A water inlet 30 communicating with the water collection cavity 15 is formed in the side wall of the seat body 1. A water guide pipe 25 covering the water inlet 30 is fixedly mounted on the side wall of the seat body 1. A sliding opening communicating with the water collection cavity 15 is formed in the wall of the semi-annular groove 14. A limiting component for limiting the movement distance of the round rod 13 is slidably disposed in the sliding opening. The limiting component includes a sliding rod 16, a second spring rod 17, and a limiting block 18, which are slidably disposed in the sliding opening. A rotating opening is provided at one end of the 6-segment groove 14. A first rotating rod is horizontally rotatably installed in the rotating opening. A limiting block 18 is fixedly sleeved on the first rotating rod. A first torsion spring 19 is sleeved on the first rotating rod. The two ends of the first torsion spring 19 are fixedly connected to the limiting block 18 and the slide rod 16, respectively. A semi-annular rotation limiting opening 20 is provided on the wall of the rotating opening with the first rotating rod as the center. A first insert rod 21 is fixedly installed on the surface of the limiting block 18. The end of the first insert rod 21 passes through the rotation limiting opening 20. A placement block is fixedly installed on the upper surface of one end of the slide rod 16 located in the water collection cavity 15. The two ends of the second spring rod 17 are fixedly connected to the surface of the placement block and the cavity wall of the water collection cavity 15, respectively.

[0053] The side wall of the base 1 has an inverted U-shaped opening, and a cooling component is fixedly installed inside the opening. The cooling component is used to reduce the temperature of the positive temperature coefficient thermistor 6 by rainwater during rainy weather. The cooling component includes a cooling plate 26 that is sealed and fixedly installed inside the opening. The part of the cooling plate 26 inside the base 1 covers the top and sides of the positive temperature coefficient thermistor 6. A water inlet groove 27 is opened on the surface outside the base 1. The bottom of the water inlet groove 27 and the bottom of the water collection cavity 15 are both provided with water outlet holes 28 that communicate with the outside. The water outlet holes 28 are used for rainwater to flow out.

[0054] When the temperature inside the seat 1 is low and it rains, the channel size for gas flow between the two opening and closing blades 5 is small. Rainwater from the outside will enter the cooling plate 26 from the water inlet 27. The part of the cooling plate 26 inside the seat 1 will cause the temperature at the positive temperature coefficient thermistor 6 to drop again, thus reducing the resistance and allowing a larger current to pass through. The magnetism of the electromagnet 7 will be stronger, and the magnetic attraction force on the magnetic block 9 will also be stronger. As the first spring rod 8 is stretched, the rack rod 12 moves upward, and multiple gears 10 will rotate the two opening and closing blades 5 to a vertical position, thereby closing the heat dissipation vent 3 and preventing rainwater from entering the seat 1 from the heat dissipation vent 3. At this time, the round rod 13 will rotate to abut against the bottom wall of the semi-annular groove 14.

[0055] After the rain stops, the water in the inlet tank 27 will slowly flow out from the outlet hole 28. Then, as the temperature inside the heat dissipation vent 3 rises, the resistance of the positive temperature coefficient thermistor 6 increases, the current that can pass through is smaller, the magnetism of the electromagnet 7 weakens, and the magnetic attraction force on the magnetic block 9 also weakens. The first spring rod 8 will then move the magnetic block 9 down, and at this time the two opening and closing blades 5 will rotate, thereby opening the heat dissipation vent 3.

[0056] When the temperature inside the seat 1 is high, the resistance of the positive temperature coefficient thermistor 6 is large, which weakens the magnetism of the electromagnet 7 and reduces the magnetic attraction force on the magnetic block 9. Due to the transmission of the rack 12 and gear 10, the round rod 13 will rotate to abut against the lower surface of the limiting block 18. Due to the restriction of the first insertion rod 21 and the rotation limit port 20, the end of the limiting block 18 away from the slide rod 16 cannot rotate upward. Thus, the limiting block 18 will block the movement of the round rod 13. At this time, the two opening and closing blades 5 can only rotate to a horizontal state and cannot continue to rotate under the elastic potential energy of the first spring rod 8.

[0057] The water collection cavity 15 is equipped with a floating component for releasing the restriction component on the round rod 13 during rainy weather. The floating component includes a float 22 that can float on the surface of rainwater, a pull rope 23, and an I-shaped guide wheel 24. The float 22 is vertically slidably disposed in the water collection cavity 15. The two ends of the pull rope 23 are fixedly connected to the lower surface of the float 22 and the end of the slide rod 16 located in the water collection cavity 15, respectively. A fixed shaft is rotatably installed on the cavity wall of the water collection cavity 15. The I-shaped guide wheel 24 is rotatably installed on one end of the fixed shaft. The pull rope 23 passes through the I-shaped guide wheel 24.

[0058] When the temperature inside the seat 1 is high and it rains, or when the temperature of the rainwater in the inlet tank 27 is too high to effectively cool the temperature of the positive temperature coefficient thermistor 6, rainwater will enter the water collection chamber 15 through the water pipe 25. As the water in the water collection chamber 15 increases, the float 22 will rise due to buoyancy. During the upward movement, the float 22 will pull the rope 23, causing the slide rod 16 to move towards the I-shaped guide wheel 24. As a result, the limiting block 18 at the end of the slide rod 16 will also move together and will no longer obstruct the round rod 13 in the semi-annular groove. When the seat 1 slides within 14, if the temperature inside the seat 1 is high, the resistance of the positive temperature coefficient thermistor 6 is large, thus the magnetism of the electromagnet 7 is weaker, and the magnetic attraction force on the magnetic block 9 is smaller. Due to the transmission and cooperation of the rack 12 and the gear 10, since the round rod 13 is not restricted by the limiting block 18 during the rotation, it will quickly rotate under the elastic potential energy of the first spring rod 8 until it abuts against the top wall of the semi-annular groove 14. At this time, the two opening and closing blades 5 will rotate to a vertical state, thereby sealing the heat dissipation port 3 and preventing rainwater from entering the interior of the seat 1 through the heat dissipation port 3.

[0059] When the rain stops, the water in the water collection chamber 15 will slowly flow out from the outlet 28. As the water level in the water collection chamber 15 drops, the float 22 will also move down. The slide bar 16 will gradually move and reset under the elastic potential energy of the second spring bar 17. When the control cabinet stops working, the temperature in the base 1 will gradually decrease. The resistance of the positive temperature coefficient thermistor 6 is small, and the magnetism of the electromagnet 7 is strong. As a result, the magnetic block 9 will move up quickly under the magnetic attraction force, and the rack bar 12 will also move up. At this time, as the round bar 13 slides down in the semi-annular groove 14, it will abut against the upper surface of the limiting block 18 and push the end of the limiting block 18 away from the slide bar 16 to rotate downward until the round bar 13 no longer abuts against the limiting block 18. At this time, the limiting block 18 will quickly rotate and reset under the elastic potential energy of the first torsion spring 19 to be horizontal with the slide bar 16.

[0060] An L-shaped locking rod 29 is fixedly installed at the top of the rack 12. Mounting blocks are symmetrically fixedly installed on the walls of the rectangular groove. A second rotating rod is horizontally rotatably mounted between the two mounting blocks. A rotating block 31 for locking the locking rod 29 is fixedly sleeved on the second rotating rod. A second torsion spring 32 is sleeved on the second rotating rod, with its two ends fixedly connected to the mounting block and the rotating block 31, respectively. An opening communicating with the through-hole and the rectangular groove is provided on the inner wall of the base 1. A semi-annular rotation-limiting groove 33 is formed on the side wall of the rotating block 31 with the second rotating rod as its center. An insertion port is provided on the surface of the mounting block near the rotation-limiting groove 33. A second insertion rod 34 is slidably inserted into the insertion port. The end of the second insertion rod 34 corresponds to the position of the rotation-limiting groove 33. The second insertion rod 34 is controlled to move laterally by a pressing component. The device includes an inclined plate 35 fixedly installed at one end of the second insert rod 34, an I-shaped slider 36, and a float 37 that can float on the surface of rainwater. The inclined plate 35 has an inclined opening 38 on its surface. The I-shaped slider 36 is slidably disposed in the inclined opening 38. The cooling plate 26 has a side opening vertically opened on its side wall that is connected to the water inlet 27. A straight rod 39 is vertically slidably disposed in the side opening. One end of the straight rod 39 located in the water inlet 27 is fixedly connected to the float 37, and the other end located outside the water inlet 27 is fixedly connected to the surface of the I-shaped slider 36. A sealing component is provided on the straight rod 39. The sealing component is used to seal the side opening. The sealing component includes a sealing plate 40 fixedly sleeved on the straight rod 39. Both the upper and lower walls of the side opening have vertically opened sealing grooves. The two ends of the sealing plate 40 are respectively slidably inserted into the two sealing grooves.

[0061] When the temperature inside the seat 1 is low and it rains, the rack 12 moves upward, controlling the two opening and closing blades 5 to rotate to a vertical position and closing the heat dissipation vent 3. During this process, rainwater enters the water inlet trough 27, causing the float 37 within the trough 27 to move upward along with the straight rod 39 and the I-shaped slider 36 due to buoyancy. The I-shaped slider 36 slides within the inclined opening 38. Under the pressure of the inclined surface, the second insert rod 34 moves laterally, and one end inserts into the top of the rotation limiting groove 33. Then, as the rack 12 moves upward, the upper surface of the locking rod 29 at the top of the rack 12... When the lower surfaces of the rotating block 31 abut against each other, the end of the rotating block 31 away from the second rotating rod will rotate upward under the pressure of the locking rod 29 until both opening and closing blades 5 rotate to a vertical position and close the heat dissipation port 3. At this time, the rotating block 31 will no longer be in contact with the locking rod 29, and the rotating block 31 will quickly rotate and reset under the elastic potential energy of the second torsion spring 32. At this time, since the end of the second insertion rod 34 is located at the top of the rotation limiting groove 33, the end of the rotating block 31 away from the second rotating rod cannot rotate downward due to the restriction of the second insertion rod 34. At this time, the locking rod 29 is blocked by the rotating block 31 and cannot move downward.

[0062] To prevent the temperature inside the base 1 from gradually rising when the heat dissipation vent 3 is closed, which would increase the resistance of the positive temperature coefficient thermistor 6 and reduce the magnetic attraction force on the magnetic block 9, the first spring rod 8 would move down with the rack rod 12, causing the two opening and closing blades 5 to rotate, thus releasing the closure of the heat dissipation vent 3 and opening it again, allowing rainwater from the outside to enter the base 1 through the heat dissipation vent 3.

[0063] Only when it stops raining will the rainwater in the inlet trough 27 slowly flow out from the outlet 28, the water level in the inlet trough 27 gradually drop, the float 37 will also drop along with it, and the I-shaped slider 36 will move down with it. During the downward movement of the I-shaped slider 36, it will control the second insert rod 34 to move laterally. The end of the second insert rod 34 will move out of the rotation limit groove 33, and the rotation restriction on the rotating block 31 will be released. At this time, when the rack rod 12 moves down with the locking rod 29, the end of the rotating block 31 away from the second rotating rod will rotate downward due to the pressure of the locking rod 29.

[0064] The surface of the opening and closing blade 5 is provided with a vent 41. The top of the heat dissipation vent 3 is provided with an air inlet 42 that communicates with the inside of the base 1. The bottom of the heat dissipation vent 3 is provided with an air outlet 43 that communicates with the outside. The longitudinal section of the air inlet 42 and the air outlet 43 are both L-shaped. The bottom surface of the bottom opening of the air outlet 43 is inclined with the inside higher than the outside. A water baffle 44 is fixedly installed on one side of the base 1. The water baffle 44 is located above the bottom opening of the air outlet 43 and is inclined. The air inlet 42, the air outlet 43 and the two vents 41 form a communication channel for gas flow.

[0065] When it rains, the two opening and closing blades 5 rotate to a vertical position, at which point the heat dissipation vent 3 will be closed. The air vents 41 on the surface of the two opening and closing blades 5 will be precisely aligned with the air inlet 42 at the top and the air outlet 43 at the bottom of the heat dissipation vent 3. The three are on the same vertical horizontal line and closely connected, forming a dedicated flow channel for directional airflow. As the electrical components inside the seat 1 continuously generate heat, the hot air, being less dense than cold air, has the characteristic of natural rising and will gradually accumulate in the upper part of the seat 1.

[0066] The accumulated hot air will spontaneously enter from the top opening of the air inlet 42, flow downward along the L-shaped channel of the air inlet 42, pass through the two connected vents 41 in sequence, and then enter the L-shaped channel of the air outlet 43, and finally be discharged to the outside from the bottom opening of the air outlet 43. This process does not require additional power to drive it. It can achieve the orderly discharge of hot air inside the seat 1 by relying on the natural convection of hot air. This avoids the hot air inside the seat 1 from being unable to be discharged after the heat dissipation vent 3 is closed, which would cause the temperature inside the seat 1 to continue to rise, and ensure that the internal components are always within the safe operating temperature range.

[0067] To further enhance the waterproof performance of the connecting channel and prevent rainwater from flowing back into the body 1 through the vent 43, the bottom surface of the vent 43 is specially designed as an inclined structure with the inside higher than the outside. Even if a small amount of rainwater enters the vent 43 due to external wind splash or airflow, the inclined bottom surface can quickly guide the rainwater to flow to the outside, preventing rainwater from stagnating in the vent 43 and forming water accumulation, thus structurally cutting off the path of rainwater backflow.

[0068] Meanwhile, the water-blocking eaves 44 can completely cover the area above and to the side of the bottom opening of the air outlet 43. When raindrops fall vertically or rain splashes from the side, the water-blocking eaves 44 can directly intercept the rainwater, preventing the rainwater from falling directly into the bottom opening of the air outlet 43. The tilt angle of the water-blocking eaves 44 can also guide the rainwater on its surface to slide quickly away from the air outlet 43, further reducing the probability of rainwater entering the circulation channel.

[0069] In summary, when the opening and closing blades 5 are vertically closed and the heat dissipation port 3 is closed in rainy weather, the flow channel formed by the air inlet 42, the vent 41, and the air outlet 43 achieves "directional discharge of hot air". The inclined bottom surface of the air outlet 43 and the water baffle 44 form a double waterproof protection of "drainage guidance + physical shielding", which not only ensures the heat dissipation needs in rainy weather, but also maximizes the waterproof reliability, achieving efficient synergy between heat dissipation and waterproofing functions.

[0070] A fixing block 45 is fixedly installed inside the bottom opening of the air outlet 43. Multiple mounting holes are equidistantly opened on the surface of the fixing block 45. A miniature blower 46 is installed in the mounting hole. A contact block 47 is fixedly installed on the surface of the rotating shaft 4 located below. A touch switch 48 located on the rotation path of the contact block 47 is fixedly installed at the bottom of the rectangular groove. The touch switch 48 is electrically connected to multiple miniature blowers 46. The fixing block 45 has a pre-set wire hole for the power cord of the miniature blower 46 to pass through. One end of the power cord passes through the wire hole and extends into the base 1 and forms an electrical connection with the touch switch 48, thus forming a complete power supply and control circuit.

[0071] When the rotating shaft 4 rotates with the opening and closing blade 5 to a vertical position, the contact block 47 will rotate synchronously with the rotating shaft 4 and precisely abut against the trigger end of the touch switch 48 to trigger the switch. When the opening and closing blade 5 leaves the vertical position, the contact block 47 rotates away from the trigger end with the rotating shaft 4, and the touch switch 48 automatically resets. When the touch switch 48 is triggered by the contact block 47, the circuit is connected, and multiple miniature blowers 46 start synchronously. When the touch switch 48 resets, the circuit is disconnected, and the miniature blowers 46 stop working.

[0072] When it rains, the opening and closing blades 5 rotate to a vertical position under the action of the cooling components or floating components. The contact block 47 on the rotating shaft 4 rotates synchronously and squeezes the touch switch 48, triggering the micro blower 46 to start. When the micro blower 46 is working, it generates outward suction force, forming a negative pressure environment in the flow channel. The hot air in the seat 1 will be accelerated from the air inlet 42 under the dual action of negative pressure suction and its own thermal buoyancy, and will flow quickly from the air outlet 41 to the air outlet 43. Finally, it will be forcibly discharged to the outside by the blower. Compared with the natural convection state, the hot air discharge efficiency is increased by 30%-50%, effectively avoiding the accumulation of temperature in the seat 1.

[0073] The high-speed airflow generated after the micro blower 46 is started can form an "airflow barrier" at the bottom opening of the air outlet 43, preventing rainwater and water mist from entering the channel in the opposite direction with the airflow. On the other hand, the high-speed airflow will drive the small amount of rainwater that may remain in the air outlet 43 to be discharged quickly. Together with the inclined bottom surface of the air outlet 43 and the water-blocking eaves 44, a dual protection of "active airflow protection + passive structural waterproofing" is formed, further reducing the risk of rainwater intrusion.

[0074] Furthermore, after the micro blower 46 accelerates the airflow, it will form a "dynamic airflow barrier" between the two opening and closing blades 5 and the gap between the two opening and closing blades 5 and the heat dissipation port 3. The kinetic energy of the high-speed airflow can directly impact and block the raindrops splashing from the outside and the diffused fog from passing through the gap. At the same time, the high-speed flow in the flow channel will continuously "take away" the air in the channel, so that the side of the gap near the channel (i.e., the "inner side") will always maintain a low pressure, while the side of the gap near the outside (i.e., the "outer side") will always be high pressure. In the end, a local air pressure difference of "low inside and high outside" will be formed in the gap area. This air pressure difference can actively "push" the rainwater near the gap away from the area. From the perspective of active protection, it can effectively prevent rainwater from entering the interior of the base 1 through the unexpected gaps between the opening and closing blades 5 and the inner wall of the opening and closing blades 5 and the heat dissipation port 3. This active airflow protection, together with the inclined bottom surface of the air outlet 43 and the passive structure waterproofing of the water baffle 44, forms a "triple protection system", which greatly improves the waterproof reliability of the base in rainy weather.

[0075] After the rain stops, the rainwater in the inlet tank 27 and the collection chamber 15 is gradually discharged through the outlet hole 28. The temperature of the positive temperature coefficient thermistor 6 rises, the magnetism of the electromagnet 7 weakens, the first spring rod 8 drives the rack rod 12 to move down, and the gear 10, along with the rotating shaft 4, disengages from the vertical state from the opening and closing blade 5. At this time, the contact block 47 rotates away from the touch switch 48 with the rotating shaft 4, the switch resets and disconnects the circuit, and the micro blower 46 automatically stops working to avoid unnecessary energy consumption, while not affecting the base to return to normal heat dissipation.

[0076] In this invention, the positive temperature coefficient thermistor 6 has a higher resistance at higher temperatures, resulting in a smaller current flow and weaker magnetism of the electromagnet 7, leading to a smaller magnetic attraction force on the magnetic block 9. Conversely, at lower temperatures, the resistance is lower, resulting in a larger current flow and stronger magnetism of the electromagnet 7, leading to a larger magnetic attraction force on the magnetic block 9. When the temperature inside the base 1 is high, the magnetic attraction force on the magnetic block 9 is smaller, resulting in a longer distance between the magnetic block 9 and the electromagnet 7, and a shorter extension distance of the first spring rod 8. At this time, all the opening and closing blades 5 are horizontal, maximizing the channel size for gas flow between them. Conversely, when the temperature inside the base 1 is low, the magnetic attraction force on the magnetic block 9 is larger, and the magnetic block 9 and the electromagnet 7 are more closely connected. The distance between the magnets 7 is relatively short, and the extension distance of the first spring rod 8 is relatively long. When the magnetic block 9 moves vertically, the rack rod 12 also moves together. As a result, multiple gears 10, which are all meshed with the rack rod 12, will drive the two rotating shafts 4 and the two opening and closing blades 5 to rotate together. The size of the channel for gas flow between the two opening and closing blades 5 will gradually decrease. That is, the two opening and closing blades 5 can rotate according to the temperature change inside the seat 1. The position of the opening and closing blades 5 is no longer constant. When the temperature inside the seat 1 is high, the size of the channel for gas flow between the two opening and closing blades 5 will increase, and when the temperature inside the seat 1 is low, the size of the channel for gas flow between the two opening and closing blades 5 will decrease. This makes it highly practical.
