Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to an energy-saving outdoor power metering box based on heat pipe heat dissipation. Background Technology

[0002] With the continuous development of power systems, outdoor power metering boxes, as key equipment for power metering and distribution, are increasingly widely used and often need to be exposed to the outdoor environment for extended periods, enduring harsh natural conditions such as sunlight, high temperatures, rain, and sandstorms. These boxes integrate numerous heat-generating components, including transformers, metering modules, and switching devices, which generate significant heat during operation. If this heat cannot be effectively dissipated in time, the internal temperature will rise continuously, affecting metering accuracy, accelerating the aging of electronic components, and even causing insulation damage or equipment failure. Existing outdoor metering boxes mostly use traditional louvered ventilation combined with natural convection for heat dissipation. This method is very ineffective in high-temperature summers or under direct sunlight. Some solutions employ forced air cooling or external heat sinks, but these often require additional power to drive the fan, and the heat sinks are prone to performance degradation due to dust accumulation or corrosion, making it difficult to balance efficient heat dissipation with long-term energy saving. In addition, some improved products attempt to use heat pipe technology to conduct heat to the outside, but their structural design is still relatively simple, lacking the ability to intelligently and adaptively adjust the heat dissipation intensity as the ambient temperature changes, and failing to effectively integrate natural cold sources such as soil heat dissipation, resulting in low heat dissipation efficiency. Therefore, this invention provides an energy-saving outdoor power metering box based on heat pipe heat dissipation. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing an energy-saving outdoor power metering box based on heat pipe cooling, overcoming the problems of low heat dissipation efficiency and inability to automatically adjust heat dissipation intensity according to internal temperature in existing equipment under high-temperature environments.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving outdoor power metering box based on heat pipe heat dissipation, comprising a base plate, on which a side extension component, a heat conduction component, and an auxiliary component are provided. The side extension component includes a square frame, on which four side plates are movably arranged in a circular array. A linkage circular plate is rotatably mounted on the square frame, and connecting steel cables are provided between the linkage circular plate and the side plates. The heat conduction component includes a heat conduction square plate, on which multiple heat dissipation pipes are uniformly fixed, and a cooling box is provided between the multiple heat dissipation pipes. The auxiliary component includes an auxiliary square cylinder, on which four heat conduction pipes are provided. Water is stored inside the heat conduction pipes. A square sliding plate is slidably mounted inside the auxiliary square cylinder, on which linkage sliding plates are symmetrically movably arranged. A linkage unit is provided between the linkage sliding plate and the linkage circular plate, and a flow control unit is provided between the square sliding plate and the cooling box.

[0005] Furthermore, the cooling box is fixedly installed on the base plate, and four connecting seats are fixedly installed on the square frame. The side plates are rotatably installed on the corresponding connecting seats. Torsion springs are installed between the side plates and the connecting seats. A square protective chamber is formed between the four side plates, and a square filter cylinder is installed in the square protective chamber.

[0006] Furthermore, each side plate is also fixedly provided with a fan-shaped strip plate. The axis of the fan-shaped strip plate is on the same straight line as the center line of the corresponding side plate and the rotating connection point of the connecting seat. An annular groove is provided on the linkage circular plate. The two ends of the connecting steel cable are fixedly connected to the annular groove and the upper end of the corresponding fan-shaped strip plate, respectively. Each connecting seat is also fixedly provided with a limiting ring to restrict the position of the connecting steel cable.

[0007] Furthermore, the heat-conducting square plate is fixedly installed on the base plate, the cooling box is fixedly installed on the lower surface of the base plate, the middle part of the heat dissipation pipe is located inside the cooling box, and multiple guide pipes are provided at both ends of the cooling box.

[0008] Furthermore, the auxiliary square tube is fixedly installed inside the square filter tube, and the heat conduction tubes are all connected to the cavity formed between the lower surface of the square slide plate and the auxiliary square tube. The lower ends of the heat conduction tubes are all in contact with the upper surface of the heat conduction plate.

[0009] Furthermore, symmetrical linkage rods are fixedly installed on both sides of the square slide plate. The linkage rods are slidably engaged with the square frame and the auxiliary square tube. The linkage slide plates are respectively set between the two corresponding linkage rods. The linkage slide plates and the corresponding linkage rods are slidably engaged. Relief springs are provided between the lower surface of the linkage slide plate and the linkage rod.

[0010] Furthermore, each linkage unit includes a transmission bevel gear, a linkage gear, and a linkage rack. A linkage bevel gear is fixedly mounted on the linkage circular plate, and the transmission bevel gear is rotatably mounted on the square frame. The transmission bevel gears mesh with the linkage bevel gears to form a gear pair. The linkage gears are fixedly mounted on the corresponding transmission bevel gears, and the linkage racks are fixedly mounted on the corresponding linkage slide plates. The linkage gears and linkage racks mesh to form a gear rack pair.

[0011] Furthermore, the flow control unit includes two strip-shaped flow control plates. Flow control rods are symmetrically fixed on the lower surface of the square slide plate. Linkage plates are fixed at the lower ends of the flow control rods. The two ends of the linkage plates are fixedly connected to the corresponding strip-shaped flow control plates. The strip-shaped flow control plates are used to limit the flow of the guide pipes on the same side of the cooling box.

[0012] Furthermore, L-shaped limiting plates are symmetrically slidably installed on the square frame. The L-shaped limiting plates are used to limit the position of the linkage slide plate, and a heat dissipation impeller is also rotatably installed on the lower surface of the auxiliary square tube.

[0013] The advantages of this invention compared with the prior art are: (1) This invention constructs a continuous heat dissipation path by passing the heat dissipation pipe through the cooling box and extending it into the soil, which greatly improves the high-temperature heat dissipation capacity of the outdoor metering box. (2) This invention utilizes the evaporation of liquid in the heat conduction pipe to drive the square slide plate to move upward, and automatically unfolds the side plate through the linkage unit, realizing adaptive air cooling adjustment with a larger ventilation area as the temperature increases. (3) This invention uses the lifting and lowering of the square slide plate to synchronously drive the strip control plate to adjust the opening of the guide pipe, so that the coolant flow rate automatically matches the temperature, avoiding continuous full flow consumption and achieving energy saving and consumption reduction. (4) This invention sets an L-shaped limit plate, which can forcibly lock the linkage slide plate in bad weather, restrict the unfolding of the side plate, prevent rainwater and sand from entering, and take into account both heat dissipation needs and outdoor safety protection.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Example: Reference Figures 1-12 An energy-saving outdoor power metering box based on heat pipe heat dissipation includes a base plate 101. The base plate 101 is provided with a side extension assembly, a heat conduction assembly, and an auxiliary assembly. The side extension assembly includes a square frame 112, which is fixedly installed on the base plate 101. Four side plates 105 are movably arranged in a circular array on the square frame 112. Four connecting seats 117 are fixedly installed on the square frame 112. The side plates 105 are rotatably installed on the corresponding connecting seats 117. A torsion spring is provided between the side plates 105 and the connecting seats 117. One end of the torsion spring is fixedly connected to the side plate 105, and the other end of the torsion spring is fixedly connected to the connecting seat 117. A square protective chamber is formed between the four side plates 105. A square filter cylinder 108 is provided in the square protective chamber and is fixedly installed on the base plate 101. In the initial position, the torsion spring between the side plate 105 and the connecting seat 117 is not compressed. At this time, the side plates 105 are all in a vertically downward state, that is, the four side plates 105 completely cover the square filter cylinder 108 to form a square protective shell. Each side plate 105 is provided with a louvered plate 106.

[0029] A linkage circular plate 123 is rotatably mounted on a square frame 112. A torsion spring is provided between the linkage circular plate 123 and the square frame 112. One end of the torsion spring is fixedly connected to the square frame 112, and the other end of the torsion spring is fixedly connected to the linkage circular plate 123. A connecting steel cable 118 is provided between the linkage circular plate 123 and the side plate 105. A fan-shaped strip 116 is also fixedly provided on the side plate 105. The axis of the fan-shaped strip 116 is on the same straight line as the center line of the corresponding side plate 105 and the connecting seat 117 at the rotatable connection point. An annular groove 124 is provided on the linkage circular plate 123. The two ends of the connecting steel cable 118 are fixedly connected to the annular groove 124 and the upper end of the corresponding fan-shaped strip 116, respectively. A limiting ring 122 is also fixedly provided on the connecting seat 117 to limit the position of the connecting steel cable 118. The connecting steel cable 118 passes through the corresponding limiting ring 122.

[0030] In the initial position, the torsion springs between the linkage circular plate 123 and the square frame 112, as well as between the side plate 105 and the connecting seat 117, are not compressed. At this time, the side plate 105 is in a vertically downward state. The linkage circular plate 123 is driven to rotate, and the torsion springs between the linkage circular plate 123 and the square frame 112 are compressed. Under the action of the linkage circular plate 123, the connecting steel cable 118 is pulled and moved. Under the action of the limiting ring 122, the position of the connecting steel cable 118 between the side plate 105 and the limiting ring 122 is restricted. Thus, under the action of the connecting steel cable 118, the lower end of the side plate 105 rotates away from the bottom plate 101. At this time, the connecting steel cable 118 is housed inside the annular groove 124. The position of the connecting steel cable 118 is restricted by the annular groove 124. At this time, the torsion springs between the side plate 105 and the connecting seat 117 are compressed. Under the action of the linkage circular plate 123, the side plate 105 can finally be in a horizontal state.

[0031] The heat-conducting component includes a heat-conducting square plate 114, which is fixedly installed on the base plate 101. Multiple heat dissipation pipes 103 are evenly fixedly arranged on the heat-conducting square plate 114. A cooling box 102 is also arranged between the multiple heat dissipation pipes 103. The cooling box 102 is fixedly installed on the lower surface of the base plate 101. The middle part of the heat dissipation pipes 103 is located inside the cooling box 102. Multiple guide pipes 104 are arranged at both ends of the cooling box 102. The guide pipes 104 on both sides of the cooling box 102 are the water inlet and the water outlet, respectively. The heat in the square protective chamber is conducted to the heat dissipation pipe 103 through the heat-conducting square plate 114. The heat moves along the heat dissipation pipe 103 towards the end. During the movement of heat on the heat dissipation pipe 103, the part of the heat dissipation pipe 103 located in the cooling box 102 is actively cooled and dissipated. The heat passing through the area of ​​the cooling box 102 is introduced into the soil for heat dissipation through the heat dissipation pipe 103 located outside the cooling box 102. The guide pipe 104 at the water inlet end is connected to the water pump to inject water into the cooling box 102. The guide pipe 104 at the water outlet end is connected to the recovery pipe. That is, the cooling water in the cooling box 102 is rapidly replaced through the guide pipes 104 on both sides.

[0032] The auxiliary component includes an auxiliary square tube 115, which is fixedly installed inside the square filter tube 108. Four heat-conducting pipes 113 are installed on the auxiliary square tube 115, and water is stored inside the heat-conducting pipes 113. A square slide plate 119 is slidably installed inside the auxiliary square tube 115. The heat-conducting pipes 113 are all connected to the cavity formed between the lower surface of the square slide plate 119 and the auxiliary square tube 115. The lower ends of the heat-conducting pipes 113 are in contact with the upper surface of the heat-conducting square plate 114. The heat in the square protective cavity heats the water in the heat-conducting pipes 113. The water vapor generated by the temperature rise moves upward along the inner wall of the heat-conducting pipes 113. The water vapor eventually enters the cavity formed between the lower surface of the square slide plate 119 and the auxiliary square tube 115, thereby increasing the volume of the cavity and pushing the square slide plate 119 upward.

[0033] It should be noted that the liquid inside the heat pipe 113 can be replaced as needed to meet different initial cooling temperature requirements.

[0034] A symmetrically movable linkage slide plate 127 is mounted on the square slide plate 119. A linkage rod 121 is symmetrically fixed on both sides of the square slide plate 119. The linkage rod 121 slides in conjunction with the square frame 112 and the auxiliary square tube 115. The linkage slide plate 127 is respectively positioned between the two corresponding linkage rods 121. The linkage slide plate 127 slides in conjunction with the corresponding linkage rod 121. A relief spring 128 is provided between the lower surface of the linkage slide plate 127 and the linkage rod 121. In the initial position, the relief springs 128 are compressed. At this time, the linkage slide plate 127 is located at the position furthest from the base plate 101 on the linkage rod 121.

[0035] A linkage unit is provided between the linkage slide plate 127 and the linkage circular plate 123. Each linkage unit includes a transmission bevel gear 131, a linkage gear 132, and a linkage rack 133. A linkage bevel gear 125 is fixedly installed on the linkage circular plate 123. The transmission bevel gear 131 is rotatably installed on the square frame 112. The transmission bevel gear 131 meshes with the linkage bevel gear 125 to form a gear pair. The linkage gear 132 is fixedly installed on the corresponding transmission bevel gear 131. The linkage rack 133 is fixedly installed on the corresponding linkage slide plate 127. The linkage gear 132 and the linkage rack 133 mesh to form a gear rack pair.

[0036] The square slide plate 119 moves upward, and the linkage rod 121 moves upward synchronously. The elastic force of the relief spring 128 is greater than the sum of the torsion spring force between the linkage circular plate 123 and the square frame 112 and the torsion spring force between the side plate 105 and the connecting seat 117. At this time, under the action of the relief spring 128, the linkage slide plate 127 moves upward synchronously, and the linkage rack 133 also moves upward synchronously. Under the action of the linkage rack 133, the linkage gear 132 rotates, and the transmission bevel gears 131 rotate synchronously. Under the action of the two transmission bevel gears 131, the linkage bevel gear 125 rotates, which causes the linkage circular plate 123 to rotate. Under the action of the linkage circular plate 123, the ends of the four side plates 105 rotate upward, thus realizing the unfolding of the four side plates 105 on the cooling box 102, thereby increasing the ventilation effect inside the square protective chamber. The higher the temperature inside the square protective chamber, the greater the upward movement of the square slide plate 119, and thus the greater the unfolding angle of the side plates 105.

[0037] A cooling impeller 126 is rotatably mounted on the lower surface of the auxiliary square tube 115. A cooling motor 120 is fixedly mounted on the auxiliary square tube 115. The output shaft of the cooling motor 120 is fixedly connected to the cooling impeller 126. When the cooling motor 120 is started, it drives the cooling impeller 126 to rotate. Under the action of the cooling impeller 126, the air below is drawn to move towards the center and then discharged from all sides, thereby improving the internal heat dissipation effect.

[0038] A flow control unit is provided between the square slide plate 119 and the cooling box 102. The flow control unit includes two strip flow control plates 110. Flow control rods 111 are symmetrically fixed on the lower surface of the square slide plate 119. Linkage plates 109 are fixedly provided at the lower ends of the flow control rods 111. The two ends of the linkage plates 109 are respectively fixedly connected to the corresponding strip flow control plates 110. The strip flow control plates 110 are used to limit the flow of the guide pipes 104 on the same side of the cooling box 102.

[0039] In the initial position, the square slide plate 119 is located closest to the base plate 101. At this time, the flow guide pipes 104 are all covered by the strip control plates 110. When the temperature inside the square protective chamber rises and the square slide plate 119 moves upward, the flow control rod 111 moves upward synchronously. Under the action of the linkage plate 109, the two strip control plates 110 also move upward synchronously, thereby gradually removing the obstruction of the flow guide pipes 104. When the square slide plate 119 moves to the position furthest from the base plate 101, the flow guide pipes 104 are in a fully open state.

[0040] A symmetrical L-shaped limiting plate 130 is slidably mounted on the square frame 112. The L-shaped limiting plate 130 is used to limit the position of the linkage slide plate 127. A bidirectional electric cylinder 129 is fixedly mounted on the square frame 112. The two piston rod ends of the bidirectional electric cylinder 129 are respectively fixedly connected to the corresponding L-shaped limiting plate 130. When using the equipment in inclement weather, the bidirectional electric cylinder 129 is first activated to move the two L-shaped limiting plates 130 towards each other, so that the L-end of the L-shaped limiting plate 130 contacts the surface of the linkage slide plate 127. Under the action of the L-shaped limiting plate 130, the linkage slide plate 127 cannot move upward, thus preventing the side plate 105 from unfolding. At this time, the temperature inside the square protective chamber rises, the linkage rod 121 moves upward, and the clearance spring 128 is compressed.

[0041] A cover 107 is also fixedly installed on the base plate 101. The cover 107 is used to cover and protect the components on the square frame 112.

[0042] Working Principle: The heat generated by the electronic components within the internal square protective chamber is passively dissipated to the underground soil via heat dissipation pipes 103, utilizing heat-conducting components. Simultaneously, the coolant inside the cooling tank 102 actively cools the portion of the heat dissipation pipes 103 located within the cooling tank 102, forming a highly efficient heat pipe heat exchange. Furthermore, the water inside the heat-conducting pipes 113 evaporates upon heating, generating pressure that drives the square sliding plate 119 upwards. This, in turn, automatically unfolds the four side plates 105 outwards via a linkage unit, increasing the ventilation and heat dissipation area. Simultaneously, the flow control unit gradually opens the coolant guide pipes 104, automatically adjusting the air cooling and liquid cooling intensity according to the internal temperature. In addition, the built-in heat dissipation impeller 126 enhances internal air turbulence, while the side plates 105 can be forcibly kept closed by L-shaped limiting plates 130 in emergency or severe weather conditions, balancing energy-saving heat dissipation with safety protection.

[0043] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
