Description
Technical Field
[0001] This invention relates to the field of meter box technology, specifically to an outdoor waterproof and heat-dissipating meter box. Background Technology
[0002] The meter box contains switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment. Generally, the meter box is installed outdoors, and its waterproof effect is relatively poor. On rainy days, rainwater may wet the meter box and seep into it, which may cause faults in the internal wiring. To address this, the meter box is usually completely sealed. However, the meter box will generate a certain amount of heat during long-term operation. If the temperature inside the fully sealed meter box is too high and cannot be dissipated, it will easily cause the wiring to age.
[0003] To address the issue of the inability to simultaneously achieve both heat dissipation and waterproofing, the existing utility model patent with publication number CN208637849U provides a waterproof and heat-dissipating meter box. It features an adjustable protective cover, allowing for adjustments to the size of the air outlet. This ensures proper ventilation within the meter box while also reducing the angle of the protective cover during windy or rainy weather to make it more difficult for rainwater to enter the meter box, thus achieving both waterproofing and heat dissipation.
[0004] In existing technologies, fans are typically installed at the air outlet to ensure heat dissipation. However, these fans can only expel heat from the inside of the meter box, leaving the internal structure still generating heat. This results in poor heat dissipation. Furthermore, if there is heavy rainfall, rainwater will collect around the meter box after passing over the top cover and drip down. The impact of rainwater and splashing from heights increase the likelihood of rainwater entering the box. If the meter box is completely sealed with a protective cover, heat dissipation cannot continue during rainy weather. Therefore, existing technologies suffer from problems with waterproofing and inadequate heat dissipation. Summary of the Invention
[0005] Therefore, the present invention provides an outdoor waterproof and heat-dissipating meter box, which effectively solves the technical problem that in the prior art, the fan can only dissipate the heat inside the box, while the structure inside the meter box itself is still in a state of heat dissipation, resulting in poor heat dissipation effect. If the meter box is completely sealed with a protective cover, it cannot continue to dissipate heat in rainy weather, resulting in unsatisfactory waterproof and heat dissipation effect.
[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: an outdoor waterproof and heat-dissipating meter box, comprising: Meter box; A heat-conducting base is embedded in a mounting plate inside the meter box. A heat dissipation pipe is installed inside the meter box. The side wall of the heat dissipation pipe is rotatably installed inside the meter box via a rotating shaft. A gas channel and a liquid channel are formed inside the heat dissipation pipe, and a drain pipe is connected to the outside of the liquid channel. Several heat-conducting tubes, one end of which is placed inside the heat-conducting base, and the other end extends into the gas channel and the liquid channel. Coolant flows inside the heat-conducting tubes. The coolant is heated and vaporized at the end of the heat-conducting tube near the heat-conducting base and flows to the end near the gas channel and the liquid channel. After cooling and condensing into liquid, it flows back. A water collection chamber is installed on the top of the meter box. The heat dissipation pipe is rotated to adjust the position of the liquid inlet at the end of the liquid channel so that it communicates with the water collection chamber or the liquid inlet is closed. A limiting component is disposed on the side of the water collection cavity and the heat dissipation pipe. The limiting component abuts against the side of the heat dissipation pipe to prevent the heat dissipation pipe from rotating, and can be lowered to no longer obstruct the heat dissipation pipe. When the heat dissipation pipe is blocked by the limiting component and remains in its original position, the liquid channel is connected to the inside of the water collection cavity through the liquid inlet, so that the liquid in the water collection cavity can flow into the liquid channel. When the heat dissipation pipe is not blocked by the limiting component, the heat dissipation pipe is rotated by force and the liquid inlet of the liquid channel is closed.
[0007] Furthermore, the height of the end of the heat pipe near the heat-conducting base is lower than the height of the end of the heat pipe near the liquid channel; After water enters the liquid channel, the liquid level in the liquid channel is higher than the end position of the heat pipe.
[0008] Furthermore, a protrusion is provided inside the liquid channel, and a connecting partition is connected to the protrusion along the direction of the liquid channel. The side of the connecting partition is connected to the inner wall of the liquid channel, and its end is higher than the end of the heat pipe. The connecting partition is positioned above the rotating shaft.
[0009] Furthermore, the inlet is connected to an inlet pipe, and the outer wall of the water collection chamber is provided with an arc-shaped slide for the end of the inlet pipe to slide, and the end of the arc-shaped slide is provided with a water passage hole. When the heat dissipation pipe is not rotating, the liquid inlet pipe is directly opposite the water passage hole. After the heat dissipation pipe rotates, the end of the liquid inlet pipe abuts against the inner wall of the arc-shaped slide and is sealed.
[0010] Furthermore, the limiting component includes an installation cavity disposed within the water collection cavity, a buoyancy seat disposed within the installation cavity, a connecting rod connected to the bottom of the buoyancy seat, and a limiting seat connected to the bottom of the connecting rod; The outer wall of the heat dissipation pipe is provided with a connecting frame, a limit block is installed on the connecting frame, and a limit groove is provided on the limit seat for the limit block to pass through; The top two sides of the mounting cavity are connected to the side of the water collection cavity, and there is a gap between the other two sides of the top of the mounting cavity and the inner wall of the water collection cavity; The top of the meter box forms a slope that connects with the edge of the water collection chamber.
[0011] Furthermore, the limiting block has a ball groove on its side, and a steel ball is installed in the ball groove. When the limiting component abuts against the side of the heat dissipation pipe, the steel ball rolls into contact with the outer wall of the limiting seat.
[0012] Furthermore, the heat pipe includes a first pipe section and a second pipe section connected in sequence; The first pipe section is a flexible tube, the second pipe section is a rigid tube, and the end of the first pipe section is connected to the side of the heat-conducting base. After the heat dissipation pipe is rotated, the inclination angle of the section of the second pipe segment away from the heat dissipation pipe increases; The mounting plate has a slot for the first pipe section to pass through.
[0013] Furthermore, a partition plate is provided inside the gas channel. The partition plate is composed of multiple bent plate segments, with one end connected to the inner wall of one side of the gas channel and the other end connected to the inner wall of the other side of the gas channel, so that a gas channel with a larger top and a smaller bottom and a smaller bottom and a smaller top are formed inside the gas channel. Several heat sinks are provided in the larger cross-sectional area of the air distribution channel. The heat pipe passes through each heat sink in sequence. A connecting seat is installed in the air distribution channel. A cooling fan facing the heat sink is provided in the connecting seat. Each side wall of the air distribution channel is provided with an air inlet and an air outlet. The air inlet and air outlet on different air distribution channels face opposite directions. The side wall of the meter box is provided with ventilation holes, and a baffle is provided on the outer wall of the meter box directly opposite the ventilation holes.
[0014] Furthermore, a water pump is installed between the drainage pipe and the liquid channel; The connection between the drain pipe and the liquid channel is close to the rotating shaft. A connecting pipe is connected inside the drain pipe, and the end of the connecting pipe extends to the bottom of the liquid channel without contacting the bottom wall of the liquid channel.
[0015] Furthermore, a mounting base is installed inside the meter box, and the rotating shaft is rotatably mounted on the mounting base. A torsion spring is provided between the mounting base and the rotating shaft. The torsion spring is wound around the outside of the rotating shaft, with one end connected to the mounting base and the other end connected to the outer wall of the rotating shaft.
[0016] Compared with the prior art, the present invention has the following advantages: In this invention, a heat dissipation pipe is installed inside the meter box. During rainy weather, the water collection chamber collects rainwater falling from above the meter box and flows it into the heat dissipation pipe, reducing the amount of rainwater falling around the meter box and the possibility of rainwater entering the meter box, thus improving the waterproof effect. In addition, the liquid in the heat dissipation pipe cools the steam in the heat conduction pipe, and the heat from the equipment is conducted to the heat dissipation pipe through the heat conduction pipe, realizing direct cooling of the corresponding equipment installed on the heat conduction base, thus improving the heat dissipation effect. By using heat dissipation pipes to introduce rainwater into the meter box and draw it out from a lower position, the height of rainwater falling is reduced by using heat dissipation pipes as a transmission medium, which reduces the amount of rainwater splashing upwards and further reduces the amount of rainwater entering the meter box, thus enhancing the waterproof effect. In non-rainy weather, the heat dissipation pipes can be rotated to close the liquid inlet of the liquid channel, reducing liquid evaporation, increasing the liquid storage time in the liquid channel and thus increasing the liquid cooling usage time. Rainwater can be recycled and reused, and in addition to being waterproof, the recycled rainwater can be used for heat dissipation, making it more energy-efficient. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] like Figures 1-6 As shown, the present invention provides an outdoor waterproof and heat-dissipating meter box, including a meter box body 1, a heat-conducting base 2, a heat dissipation pipe 3, a heat-conducting pipe 4, a water collection cavity 5, a limiting component 6, and other structures.
[0022] The meter box 1 is generally equipped with a mounting plate 7 for equipment installation. Measuring instruments, switching equipment, etc. are all installed on the mounting plate 7. The heat-conducting base 2 is embedded in the mounting plate 7 inside the meter box 1. To further achieve heat conduction, the mounting plate 7 is made of heat-conducting material, or a heat-conducting base 2 is set at each equipment installation position to achieve heat conduction and heat dissipation for measuring instruments, switching equipment, etc.
[0023] The heat dissipation pipe 3 is installed inside the meter box 1. The heat dissipation pipe 3 forms a gas channel 9 and a liquid channel 10. The liquid channel 10 is connected to a drain pipe 11, and the liquid in the liquid channel 10 can be discharged through the drain pipe 11.
[0024] In this invention, the drainage pipe 11 leads the liquid in the liquid channel 10 out of the meter box 1 at a lower position, and the heat dissipation pipe 3 introduces rainwater into the meter box 1 and leads it out from a lower position. By using the heat dissipation pipe 3 as the transmission medium, the height of the rainwater falling is reduced, the upward splashing of rainwater is reduced, and the entry of rainwater into the meter box 1 is further reduced, thereby enhancing the waterproof effect.
[0025] Each heat-conducting base 2 generally corresponds to several heat-conducting pipes 4. One end of each heat-conducting pipe 4 is placed inside the heat-conducting base 2, and the other end extends into the gas channel 9 and the liquid channel 10. Coolant flows inside the heat-conducting pipe 4. The coolant is heated and vaporized at the end of the heat-conducting pipe 4 near the heat-conducting base 2 and flows to the end near the gas channel 9 and the liquid channel 10. After cooling and condensing into liquid, it flows back.
[0026] The heat dissipation pipe 3 cools the heat pipe 4 using water cooling or air cooling. Water cooling uses the liquid in the liquid channel 10 to cool the end of the heat pipe 4, while air cooling uses the airflow in the gas channel 9 to cool the end of the heat pipe 4. Under normal circumstances, water cooling is sufficient to cool the end of the heat pipe 4, and air cooling is generally not required. If there is no rain for a long time, the liquid in the liquid channel 10 may gradually evaporate along the drain pipe 11, resulting in insufficient liquid in the liquid channel 10 to complete the cooling. In this case, air cooling is required to cool the end of the heat pipe 4 simultaneously, or the activation and rate of air cooling may be controlled and adjusted according to the heat dissipation requirements of the equipment.
[0027] The heat dissipation pipe 3 can rotate inside the meter box 1. The side wall of the heat dissipation pipe 3 is rotatably installed inside the meter box 1 via the rotating shaft 8. Rotating the heat dissipation pipe 3 to different positions can put the heat dissipation pipe 3 into different processes.
[0028] like Figure 3As shown, the water collection chamber 5 is installed on the top of the meter box 1. The water collection chamber 5 is used to collect rainwater from the top of the meter box 1 and supply it into the heat dissipation pipe 3. The heat dissipation pipe 3 is rotated to adjust the position of the liquid inlet 12 at the end of the liquid channel 10 to communicate with the water collection chamber 5 or to close the liquid inlet 12. When the liquid inlet 12 at the end of the liquid channel 10 is connected to the water collection chamber 5, the rainwater in the water collection chamber 5 flows into the liquid channel 10. When the liquid inlet 12 at the end of the liquid channel 10 is closed, the liquid channel 10 is closed.
[0029] In this invention, a heat dissipation pipe 3 is installed inside the meter box 1. During rainy weather, the water collection chamber 5 collects all the rainwater falling from above the meter box 1 and flows into the heat dissipation pipe 3, reducing the amount of rainwater falling around the meter box 1 and reducing the possibility of rainwater entering the meter box 1, thus improving the waterproof effect. In addition, the liquid in the heat dissipation pipe 3 is used to cool the steam in the heat conduction pipe 4, and the heat from the equipment is conducted to the heat dissipation pipe 3 through the heat conduction pipe 4, thereby achieving direct cooling of the corresponding equipment installed on the heat conduction base 2 and improving the heat dissipation effect.
[0030] like Figure 3 As shown, the limiting component 6 is set on the side of the water collection cavity 5 and the heat dissipation pipe 3. The limiting component 6 mainly restricts the position of the heat dissipation pipe 3 in the meter box 1. The limiting component 6 abuts against the side of the heat dissipation pipe 3 to prevent the heat dissipation pipe 3 from rotating, and can be lowered to no longer block the heat dissipation pipe 3. That is, the limiting component 6 controls the rotation of the heat dissipation pipe 3.
[0031] When the heat dissipation pipe 3 is blocked by the limiting component 6 and remains in its original position, the liquid channel 10 is connected to the inside of the water collection cavity 5 through the liquid inlet 12, so that the liquid in the water collection cavity 5 can flow into the liquid channel 10. When the heat dissipation pipe 3 is not blocked by the limiting component 6, the heat dissipation pipe 3 is rotated by force and the liquid inlet 12 of the liquid channel 10 is closed.
[0032] In non-rainy weather, the heat dissipation pipe 3 can be rotated to close the liquid inlet 12 of the liquid channel 10, reducing liquid evaporation and increasing the liquid storage time in the liquid channel 10, thereby increasing the liquid cooling time. If the equipment generates a lot of heat per unit time, and the heat is conducted to the liquid in the heat dissipation pipe 3 and not discharged in time, the liquid water cooling in the heat dissipation pipe 3 cannot achieve complete heat dissipation, and air cooling is required for better heat dissipation.
[0033] The main feature of this invention is the design of a heat dissipation pipe 3 that can store and recycle rainwater. By controlling the state of the heat dissipation pipe 3 under different weather conditions, different processes are achieved: In the initial state, the heat dissipation pipe 3 is in an inclined state, and the liquid inlet 12 is connected to the water collection chamber 5. When it rains, the rainwater in the water collection chamber 5 enters the heat dissipation pipe 3. At this time, the limiting component 6 will block the heat dissipation pipe 3, and it cannot rotate even under force. The liquid continues to enter the heat dissipation pipe 3 and then discharged, thereby cooling the end of the heat conduction pipe 4. When the rainy weather ends, the drainage pipe 11 stops draining water. After a period of time, the limiting component 6 descends and no longer blocks the heat dissipation pipe 3. The heat dissipation pipe 3 rotates counterclockwise, and the liquid inlet 12 is sealed to prevent the liquid from evaporating. This invention recycles and reuses rainwater, and on the basis of waterproofing, it uses the recycled rainwater for heat dissipation, which is more energy-efficient.
[0034] A capillary layer is usually set inside the heat pipe 4. Under the action of gravity and capillary action, the liquid will flow from one end of the heat pipe 4 to the other end. To further promote this process, a height difference needs to be formed at the two ends of the heat pipe 4. That is, the height of the end of the heat pipe 4 near the heat-conducting base 2 is lower than the height of the end of the heat pipe 4 near the liquid channel 10. After the coolant is heated and vaporized at the end of the heat pipe 4 near the heat-conducting base 2, it flows to the end near the gas channel 9 and the liquid channel 10. After being cooled and condensed into liquid, it accelerates backflow under the action of capillary action and gravity.
[0035] When water enters the liquid channel 10, the liquid level in the liquid channel 10 should be higher than the end of the heat pipe 4. Only when the liquid level in the liquid channel 10 is higher than the end of the heat pipe 4 will the liquid in the liquid channel 10 have a certain cooling effect on the heat pipe 4. When the liquid level in the liquid channel 10 is lower than the end of the heat pipe 4, the liquid in the liquid channel 10 will not have a cooling effect on the heat pipe 4. In this case, air cooling is required to cool the end of the heat pipe 4.
[0036] In this invention, the heat dissipation pipe 3 is required to rotate under force, and the force on the heat dissipation pipe 3 can be provided by gravity. Specifically, as shown in the figure... Figure 11 and Figure 12 As shown, a protrusion 13 is provided inside the liquid channel 10. A connecting partition 14 is connected to the protrusion 13 along the direction of the liquid channel 10. The side of the connecting partition 14 is connected to the inner wall of the liquid channel 10, and its end is higher than the end of the heat pipe 4. The connecting partition 14 is located above the position directly opposite the rotating shaft 8. The connecting partition 14 is L-shaped, and both ends of the connecting partition 14 are connected to the inner wall of the liquid channel 10.
[0037] In the above embodiments, the liquid flowing down from the inlet 12 gradually enters the bottom of the liquid channel 10. When the liquid level rises to the bottom of the connecting partition 14, the liquid continues to rise along the connecting partition 14, and the liquid level on the left side of the connecting partition 14 continues to rise until the liquid on the left side of the connecting partition 14 in the heat dissipation pipe 3 is full.
[0038] The heat dissipation pipe 3 is generally designed as a symmetrical pipe structure. The pivot 8 is located on the heat dissipation pipe 3 near the middle. The design of the connecting partition 14 is such that the volume of liquid in the area above the pivot 8 in the liquid channel 10 is less than the volume of liquid in the area below the pivot 8 in the liquid channel 10. This is mainly to create a gravity difference between the upper and lower pipe sections after liquid is injected into the heat dissipation pipe 3 evenly. With the pivot 8 as the dividing point, the heat dissipation pipe 3 above the pivot 8 is the upper pipe section, and the heat dissipation pipe 3 below the pivot 8 is the lower pipe section. In the initial state, the upper pipe section is tilted to the right, and the lower pipe section is tilted to the left. When a gravity difference is formed between the upper and lower pipe sections, the gravity of the lower pipe section is greater than that of the upper pipe section, causing the lower pipe section to rotate counterclockwise to a near-vertical state. The entire heat dissipation pipe 3 also rotates counterclockwise to a near-vertical state.
[0039] In actual operation, the liquid level in the liquid channel 10 cannot be precisely controlled. Generally, when liquid flows into the liquid channel 10, the liquid stays at the bottom of the liquid channel 10, and the top of the liquid channel 10 has not yet been filled with liquid. When the liquid channel 10 is filled with liquid below the rotating shaft 8 and there is no liquid in the liquid channel 10 above the rotating shaft 8, the gravity difference between the upper and lower pipe sections is the greatest. When the liquid channel 10 is gradually filled with liquid above the rotating shaft 8, the gravity difference between the upper and lower pipe sections decreases. When the liquid channel 10 is completely filled with liquid, the gravity difference between the upper and lower pipe sections is sufficient to keep the heat dissipation pipe 3 in a vertical state.
[0040] Therefore, the above design is mainly to provide a rotational force to the heat dissipation pipe 3 when it is filled with water, without the need for external force. The rotation of the heat dissipation pipe 3 causes a change in its own position and orientation. The closed state of the heat dissipation pipe 3 changes before and after the change, so as to adapt to the heat dissipation process under different weather conditions.
[0041] To ensure that the heat dissipation pipe 3 can be reset, the present invention also includes the following design features, such as... Figure 4 As shown, a mounting base 30 is installed inside the meter box 1, and a rotating shaft 8 is rotatably mounted on the mounting base 30. A torsion spring is provided between the mounting base 30 and the rotating shaft 8. The torsion spring is wound around the outside of the rotating shaft 8, with one end connected to the mounting base 30 and the other end connected to the outer wall of the rotating shaft 8.
[0042] Under normal conditions, the heat dissipation pipe 3 is in an inclined state. When the heat dissipation pipe 3 rotates due to its own gravity, the heat dissipation pipe 3 gradually tends to be vertical.
[0043] To achieve the adjustment of the closed state of the heat dissipation pipe 3 under different orientations, the present invention makes the following design, such as... Figure 7 As shown, the liquid inlet 12 is connected to the liquid inlet pipe 15. The outer wall of the water collection chamber 5 is provided with an arc-shaped slide 16 for the end of the liquid inlet pipe 15 to slide. The end of the arc-shaped slide 16 passes through a water passage 17. When the heat dissipation pipe 3 is not rotated, the liquid inlet pipe 15 is directly opposite the water passage 17. After the heat dissipation pipe 3 is rotated, the end of the liquid inlet pipe 15 abuts against the inner wall of the arc-shaped slide 16 and is sealed.
[0044] In its natural state, the heat dissipation pipe 3 is not rotating and is tilted. The liquid inlet pipe 15 is directly opposite the water passage 17. At this time, the liquid channel 10 and the water collection chamber 5 are connected. When the heat dissipation pipe 3 rotates due to its own weight, the heat dissipation pipe 3 gradually becomes vertical. The liquid inlet pipe 15 slides along the inner wall of the arc-shaped slide 16, and the opening of the liquid inlet pipe 15 is also closed by the inner wall of the arc-shaped slide 16.
[0045] The limiting component 6 can control the position and orientation of the heat dissipation pipe 3, specifically, as follows: Figure 9 , Figure 10 and Figure 11 As shown, the limiting component 6 includes an installation cavity 61 disposed in the water collection cavity 5, a buoyancy seat 62 disposed in the installation cavity 61, a connecting rod 63 connected to the bottom of the buoyancy seat 62, and a limiting seat 64 connected to the bottom of the connecting rod 63. A connecting frame 65 is provided on the outer wall of the heat dissipation pipe 3. A limiting block 66 is installed on the connecting frame 65, and a limiting groove 67 is provided on the limiting seat 64 for the limiting block 66 to pass through.
[0046] During rainy weather, rainwater will enter the installation cavity 61, causing the liquid level in the installation cavity 61 to rise. The buoyancy seat 62 will rise accordingly, driving the limit seat 64 to rise. When the limit seat 64 rises to a certain position, if the heat dissipation pipe 3 is subjected to force and wants to rotate, the limit seat 64 will block the limit block 66, and the heat dissipation pipe 3 cannot rotate. In non-rainy weather, the liquid in the mounting cavity 61 will evaporate quickly, the liquid level will drop, the buoyancy seat 62 will drop accordingly, and the limiting seat 64 will drop. When the limiting seat 64 drops to a certain position, the limiting block 66 can pass through the limiting groove 67. At this time, the limiting seat 64 will not block the limiting block 66, nor will it block the heat dissipation pipe 3.
[0047] In rainy weather, if the liquid channel 10 contains liquid before the mounting cavity 61, the heat dissipation pipe 3 may rotate first, while the buoyancy seat 62 in the mounting cavity 61 has not yet risen in time. At this time, the limiting block 66 is very likely to pass through the limiting groove 67, so that the liquid inlet 12 is no longer aligned with the water passage hole 17, and no more liquid can enter. Rainwater will also flow directly into the meter box 1 through the water passage hole 17.
[0048] To avoid the above situation, the present invention also makes the following design: the top two sides of the mounting cavity 61 are connected to the side of the water collection cavity 5, and there is a gap 68 between the other two sides of the top of the mounting cavity 61 and the inner wall of the water collection cavity 5. Under this condition, a small part of the rainwater enters the water collection cavity 5 through the gap 68, and most of the rainwater is more likely to enter the mounting cavity 61, and then overflows from the mounting cavity 61 into the water collection cavity 5. As a result, the liquid level in the mounting cavity 61 will definitely rise faster, so that the limiting seat 64 will rise before the heat dissipation pipe 3 rotates under gravity. When the heat dissipation pipe 3 is filled with enough liquid and has a tendency to rotate under gravity, it will be blocked by the limiting seat 64.
[0049] To further prevent the limiting component 6 from not activating when the heat dissipation pipe 3 rotates, the following can be achieved: when the heat dissipation pipe 3 has not yet rotated, there is a certain distance between the heat dissipation pipe 3 and the limiting component 6. In this case, even if the heat dissipation pipe 3 rotates a small angle in advance, it has not yet reached or has just reached the limiting component 6. When the limiting block 66 follows and reaches the side of the limiting seat 64, the limiting seat 64 has already risen, thereby blocking the heat dissipation pipe 3.
[0050] After the liquid in the mounting cavity 61 has evaporated, the limiting seat 64 will no longer block the limiting block 66, and the water passage hole 17 will be in the open state. During this process, the liquid in the water collection cavity 5 will also evaporate, so it will not flow into the meter box 1 through the water passage hole 17. In practical applications, structures such as fans can also be used to help the rainwater in the water collection cavity 5 and the mounting cavity 61 evaporate. In addition, a filter screen can be installed above the mounting cavity 61 and the water collection cavity 5 to prevent fallen leaves from entering. The fan in the water collection cavity 5 can also blow away and remove the fallen leaves on the filter screen.
[0051] To further improve the water collection effect, a slope 18 is formed on the top of the meter box 1, which connects with the side of the water collection cavity 5. Rainwater flows into the installation cavity 61 or the water collection cavity 5 along the slope 18.
[0052] When the limiting block 66 abuts against the side of the limiting seat 64, a certain frictional force is generated, which prevents the limiting seat 64 from rising or falling. This may cause the limiting seat 64 to fail to follow the liquid level in the mounting cavity 61. To address this, the present invention makes the following design, as follows: Figure 8 , Figure 12 and Figure 13 As shown, the side of the limiting block 66 is provided with a ball groove 69, and a steel ball 610 is installed in the ball groove 69. When the limiting component 6 abuts against the side of the heat dissipation pipe 3, the steel ball 610 rolls in contact with the outer wall of the limiting seat 64.
[0053] In the above embodiments, the rolling friction force formed between the limiting block 66 and the limiting seat 64 is negligible relative to the buoyancy force on the limiting seat 64, the connecting rod 63, and the buoyancy seat 62 as a whole, and will not affect the lifting process of the limiting seat 64.
[0054] When the heat dissipation pipe 3 is in different orientations, the angle of the heat conduction pipe 4 will also change accordingly, resulting in different heat dissipation effects. Specifically, for example... Figure 6 As shown, the heat pipe 4 includes a first pipe section 41 and a second pipe section 42 connected in sequence; the first pipe section 41 is a flexible tube, the second pipe section 42 is a rigid tube, and the end of the first pipe section 41 is connected to the side of the heat-conducting base 2. After the heat dissipation pipe 3 is rotated, the inclination angle of the section of the second pipe section 42 that is far away from the heat dissipation pipe 3 increases.
[0055] The design of flexible and rigid tubes facilitates the movement of the heat pipe 4 along with the heat dissipation pipe 3, preventing the heat pipe 4 from pulling on the heat dissipation pipe 3. The flexible tube can be a silicone-based soft heat pipe 4 with good thermal conductivity, while the rigid tube can be a metal-based heat pipe 4. During the process of the heat dissipation pipe 3 changing from an inclined state to a vertical state, the section of the second tube 42 away from the heat dissipation pipe 3 will gradually change from a horizontal state to a downward inclination. When the second tube 42 is adjusted to a downward inclination, the cooled coolant will flow more quickly along the second tube 42 to the equipment end. The liquid flow speed per unit time increases, thereby accelerating the heat dissipation rate. Compared with rainy weather, the heat dissipation rate will be faster in non-rainy weather. The segmented design of the heat pipe 4 avoids affecting the rotation of the heat dissipation pipe 3 and differentiates the heat dissipation process under different weather conditions, achieving adaptive adjustment of the heat dissipation effect.
[0056] In addition, such as Figure 2 As shown, the mounting plate 7 has a slot 19 for the first pipe section 41 to pass through, and the slot 19 fits the shape of the first pipe section 41.
[0057] To further achieve air cooling, the present invention also includes the following design features, such as... Figure 11 and Figure 12 As shown, a partition plate 20 is provided inside the gas channel 9. The partition plate 20 is composed of multiple bent plate segments, and one end of the partition plate 20 is connected to the inner wall of one side of the gas channel 9 and the other end is connected to the inner wall of the other side of the gas channel 9, so that a gas separation channel 21 with a larger upper part and a smaller lower part and a larger lower part and a smaller upper part is formed inside the gas channel 9. Several heat sinks 22 are installed in the larger cross-sectional area of the air distribution channel 21. Heat pipes 4 pass through each heat sink 22 in sequence. A connecting seat 23 is installed in the air distribution channel 21, and a cooling fan is installed in the connecting seat 23 facing the heat sink 22.
[0058] Taking one of the air distribution channels 21 as an example, the cooling fan blows air onto the heat sink 22. The design of the heat sink 22 increases the contact area between the heat pipe 4 and the air, thus cooling the heat pipe 4. After passing through the heat sink 22, the airflow area in the air distribution channel 21 becomes smaller, creating resistance to the airflow. This further makes the air stay in the heat sink 22 area for a longer time, promoting the heat conduction process.
[0059] Each air distribution channel 21 has an air inlet 24 and an air outlet 25 on its side wall. The air inlet 24 and the air outlet 25 on different air distribution channels 21 face opposite directions. That is, the air inlet 24 and the air outlet 25 on different air distribution channels 21 are set on different sides to avoid the situation where the air inlet 24 and the air outlet 25 of adjacent air distribution channels 21 are on the same side, causing the hot air that has just been discharged from one air distribution channel 21 to be sucked into another air distribution channel 21.
[0060] Furthermore, such as Figure 3 As shown, the side wall of the meter box 1 is provided with a ventilation hole 26, and a baffle 27 is provided on the outer wall of the meter box 1 directly opposite the ventilation hole 26. Gas can enter the meter box 1 through the ventilation hole 26 and enter the gas distribution channel 21 under the force of the cooling fan.
[0061] To further achieve waterproofing inside the meter box 1, the mounting plate 7 can be designed as follows: the mounting plate 7 is installed upright inside the meter box 1, dividing the inside of the meter box 1 into two chambers, front and rear, which are not connected. The front chamber is used to install various equipment, and the rear chamber is used to install heat dissipation structures such as heat dissipation pipes 3. The ventilation hole 26 is connected to the rear chamber. With this design, rainwater can be completely prevented from entering the front chamber of the meter box 1 and affecting the equipment, and heat dissipation is achieved through contact heat conduction, thus achieving heat dissipation while isolating the equipment.
[0062] In this invention, the drainage pipe 11 has the function of drainage, specifically, as follows: Figure 6 As shown, a water pump 28 is installed between the drainage pipe 11 and the liquid channel 10.
[0063] In this invention, the drainage of the drainage pipe 11 is adjusted according to different weather conditions. Therefore, a control circuit can be designed inside the meter box 1 to control the drainage action of the drainage pipe. The control circuit can obtain the weather conditions in real time, and thus control the start or stop of the water pump 28 based on the weather conditions. It can also control the power of the water pump 28 based on the rainfall, so as to collect and guide the rainwater above the meter box 1 as much as possible, so as to prevent rainwater from falling from the top of the meter box 1.
[0064] If the drain pipe 11 is located near the bottom of the heat dissipation pipe 3, the heat dissipation pipe 3 will need to resist the gravity of the drain pipe 11 when it is tilted. The location of the drain pipe 11 may prevent the heat dissipation pipe 3 from being initially tilted. The weight of the drain pipe 11 may affect the rotation of the heat dissipation pipe 3. To reduce this effect, the connection between the drain pipe 11 and the liquid channel 10 can be located close to the rotating shaft 8. The gravity of the drain pipe 11 itself will not generate a large torsional force on the heat dissipation pipe 3. Based on this, the heat dissipation pipe 3 will not have a significant impact on the drain pipe 11 during rotation within a small angle range.
[0065] like Figure 11 and Figure 12 As shown, a connecting pipe 29 is connected inside the drain pipe 11. The end of the connecting pipe 29 extends to the bottom of the liquid channel 10 and does not contact the bottom wall of the liquid channel 10, so as to facilitate the discharge of liquid in the heat dissipation pipe 3 as much as possible.
[0066] When it is not rainy but rainy weather is imminent, the heat dissipation pipe 3 needs to be reset to its initial state to facilitate the injection of rainwater. Therefore, before the rainy weather arrives, the liquid in the heat dissipation pipe 3 is drained, and there is no longer a gravity difference inside the heat dissipation pipe 3. Under the action of the torsion spring, the heat dissipation pipe 3 can be reset to its initial state, so that the liquid inlet pipe 15 is aligned with the water passage hole 17 to facilitate the inflow of rainwater.
[0067] In summary, the main implementation process of this invention is as follows: In the initial state, under the action of the torsion spring, the heat dissipation pipe 3 is in an inclined state, and the liquid inlet pipe 15 is directly opposite the water passage hole 17. During rainy weather, rainwater flows down the slope 18. A small portion of the rainwater enters the water collection chamber 5 through the gap 68, while most of the rainwater enters the installation chamber 61 and then overflows from the installation chamber 61 into the water collection chamber 5. During the process of rainwater entering the water collection chamber 5, the liquid level in the installation chamber 61 rises, the buoyancy seat 62 rises accordingly, and drives the limit seat 64 to rise. After rising, the limit groove 67 on the limit seat 64 is no longer in the movement path of the limit block 66. At the same time, rainwater enters the liquid channel 10 through the water inlet 17 and the liquid inlet pipe 15. The liquid enters the bottom of the liquid channel 10, and the liquid level in the liquid channel 10 gradually rises. A gravity difference is formed between the upper and lower pipe sections of the heat dissipation pipe 3, which drives the heat dissipation pipe 3 to rotate counterclockwise. Since the limit seat 64 has risen to a certain position at this time, if the heat dissipation pipe 3 is subjected to force and wants to rotate, the limit seat 64 will block the limit block 66, and the heat dissipation pipe 3 cannot rotate. When the liquid channel 10 is filled with liquid, the water pump 28 is driven to continuously discharge the rainwater in the liquid channel 10 at a certain speed through the drainage pipe 11, so that the rainwater in the installation cavity 61 and the water collection cavity 5 continuously flows into the liquid channel 10 and is discharged from the drainage pipe 11. After the rainy weather, the liquid in the installation cavity 61 will evaporate quickly, the liquid level will drop, the buoyancy seat 62 will drop accordingly, and the limiting seat 64 will drop. When the limiting seat 64 drops to a certain position, the limiting block 66 can pass through the limiting groove 67. At this time, the limiting seat 64 will not block the limiting block 66, nor will it block the heat dissipation pipe 3. The heat dissipation pipe 3 can smoothly change from an inclined state to a vertical state. As the heat dissipation pipe 3 rotates under its own weight, it gradually becomes more vertical. The liquid inlet pipe 15 slides along the inner wall of the arc-shaped slide 16, and the opening of the liquid inlet pipe 15 is sealed by the inner wall of the arc-shaped slide 16. At the same time, the drain pipe 11 stops draining. The liquid in the liquid channel 10 continuously cools the end of the heat pipe 4; When it is not rainy but rainy weather is imminent, the water pump 28 is started to discharge all the liquid in the liquid channel 10 through the drainage pipe 11, so that the heat dissipation pipe 3 is reset to the initial state under the action of the torsion spring, and the liquid inlet pipe 15 is aligned with the water passage hole 17 to facilitate the flow of rainwater.
