Description

Technical Field

[0001] This invention belongs to the field of outdoor power distribution cabinet technology, specifically relating to a protective outdoor power distribution cabinet. Background Technology

[0002] Outdoor distribution cabinets are power distribution and control devices specifically designed for outdoor environments. They are mainly used in construction sites, residential power supply, road lighting, communication base stations, and new energy systems. They are waterproof, dustproof, and corrosion-resistant to ensure the safe and stable operation of electrical systems under complex climatic conditions. Their core function is to distribute, control, monitor, and protect low-voltage power. They are widely used in power distribution scenarios in industries, construction, and commerce. Low-voltage distribution cabinets integrate multiple electrical components into one cabinet, facilitating maintenance, repair, and management, and improving the reliability and maintainability of the system.

[0003] In the existing technology, in order to ensure that the outdoor power distribution cabinet has a certain heat dissipation performance, heat dissipation holes are symmetrically opened on the outer side wall of the outdoor power distribution cabinet to achieve heat dissipation through convection. However, since the heat dissipation holes are exposed, rainwater falling at an angle can easily enter the power distribution cabinet in rainy weather, especially in strong convective weather, which may cause corrosion of electrical equipment or even short circuits.

[0004] Therefore, a protective outdoor power distribution cabinet is proposed. Summary of the Invention

[0005] This invention provides a protective outdoor power distribution cabinet, the purpose of which is to solve the problems mentioned above.

[0006] This invention provides a protective outdoor power distribution cabinet, including a cabinet body composed of two side panels, a back panel, and two top and bottom panels.

An external rain guard assembly and an internal heat dissipation assembly are provided on the side panel.

[0007] Furthermore, the external rain shield assembly includes a rain shield plate that slides on one side of the outer wall of the side plate. Two external racks and two external mating blocks are symmetrically arranged on the outer wall of the rain shield plate facing the side plate. The external racks are located above the external mating blocks and mesh with the linkage gear. The external mating blocks are fixedly connected to the top of the spring. An air inlet is provided on one side of the outer wall of the rain shield plate near the two external racks, and an electromagnet is embedded therein. An air inlet cover is provided on the outer wall of the rain shield plate away from the side plate near the air inlet. A plurality of air inlet holes are equally spaced at the bottom of the air inlet cover.

[0008] Furthermore, a rain collection hood is provided on the outer wall of the rain shield away from the side plate, near the upper part of the air intake hood. An outer edge plate is provided on the top outer edge of the rain collection hood, and two limiting sleeves are symmetrically arranged on the inner bottom of the rain collection hood. A fixed contact and a second spring are provided on the inner center of the inner bottom of the rain collection hood near the inner side of the limiting sleeve. The fixed contact is located inside the second spring. A guide post is provided on the top of the second spring. A moving contact is provided on the bottom of the guide post near the fixed contact directly above it. A pressure plate is provided on the top of the guide post. A traction rack is provided on one outer wall of the rain collection hood, and a through hole is opened on one outer wall of the rain collection hood near the maximum moving height of the pressure plate to allow rainwater to drain slowly.

[0009] Furthermore, the internal heat dissipation assembly includes an internal movable plate that slides on the outer wall of the other side of the side plate. Two internal racks are symmetrically arranged on the outer wall of the internal movable plate facing the side plate. The internal racks mesh with a linkage gear. An active heat dissipation groove and two passive heat dissipation grooves are formed on the outer wall of the internal movable plate near the two internal racks. The active heat dissipation groove is located between the two passive heat dissipation grooves. A fixed cover is provided on the outer wall of the internal movable plate away from the side plate and near the outer side of the active heat dissipation groove. A fan is provided on the inner side wall of the fixed cover. An abutment is provided on the top of the fixed cover near the limit switch directly below it.

[0010] Furthermore, a number of electrical mounting brackets are provided at equal intervals in the vertical direction on one side of the outer wall of the back plate near the two side plates, and a cooling groove is provided on the top of the back plate. A drain outlet is provided on the other side of the outer wall of the back plate near the bottom position, and the drain outlet is connected to the cooling groove.

[0011] Furthermore, two guide grooves are symmetrically opened at the top of the rain shield, and an arc groove is embedded in the top of the rain shield and located on the guide groove. A baffle plate is rotatably connected inside the arc groove. The baffle plate is composed of an inclined plate one, an inclined plate two, and a vertical plate. The inclined plate one and the inclined plate two are fixed together on the same axis. The vertical plate is located at the joint of the inclined plate one and the inclined plate two and is vertically connected. A traction gear is provided at the axial end of the baffle plate. The traction gear meshes with the traction rack.

[0012] Furthermore, the outer wall of the side plate is provided with a mating groove for the vertical movement of the outer rack and the inner rack, and the rain shield and the inner moving plate are in a dynamic sealing fit with the outer wall of the side plate. By adopting the above technical solution, the groove design ensures that the rain shield and the inner movable plate can move up and down along the outer side wall of the side plate. The dynamic seal ensures the sealing of the rain shield and the inner movable plate as they move along the side plate, preventing rainwater leakage and ensuring the airtightness of the outdoor power distribution cabinet.

[0013] Furthermore, a metal block is embedded in one outer wall of the side plate and magnetically attracted to the electromagnet that has been energized and generated magnetism. The fixed contact, moving contact, electromagnet and external power supply constitute a circuit path. By adopting the above technical solution, a complete circuit structure can be formed by utilizing the structure of the formed path. When the fixed contact and the moving contact come into contact, the circuit structure that was originally in a closed state becomes an open circuit structure. At this time, after the electromagnet loses the power supply from the external power source, the electromagnet is de-energized and loses its magnetism.

[0014] Furthermore, the module and number of teeth between the traction gear and the traction rack can enable the traction gear to rotate precisely at a certain angle corresponding to the traction rack moving a specific distance; By adopting the above technical solution and utilizing the special design of the module and number of teeth, the external rainproof component moves downward under the action of rainwater gravity. Then, through the meshing of the traction rack and traction gear, the baffle plate rotates and is positioned at the designed angle. Specifically, the inclined plate two forms an angle with the arc groove, the inclined plate one is located inside the arc groove, and the gap between the vertical plate and the arc groove allows rainwater to pass through. The rainwater flows downward along the inner wall of the cooling tank.

[0015] Furthermore, the arc groove and the cooling groove are connected, and the inner circumferential surface of the arc groove matches and fits the outer wall of the baffle plate. By adopting the above technical solution, the interconnected structure allows rainwater to enter the arc groove under the guidance of the flow channel, and then enter the cooling tank through the arc groove. Through the flow of rainwater in the cooling tank, the back panel is cooled and dissipated through heat exchange, thereby achieving heat dissipation of the power distribution cabinet. The rotation of the baffle plate in the arc groove ensures the sealing of the baffle plate during its rotation.

[0016] The beneficial effects of this invention are as follows: 1. This invention enables outdoor power distribution cabinets to have a certain self-heating capacity on sunny days through the linkage between the external rainproof component and the internal heat dissipation component. The convection design ensures that air can pass through the outdoor power distribution cabinet for heat dissipation, which meets the heat dissipation needs of power distribution cabinets with small-power electrical equipment installed inside. In rainy weather, the heat dissipation holes used for convection heat dissipation are blocked, and the fan is forced to turn on for active heat dissipation, avoiding the problem of heat not being effectively dissipated due to the blockage of the heat dissipation holes. The weight characteristics of rainwater are fully utilized to activate the linkage between the external rainproof component and the internal heat dissipation component.

[0017] 2. This invention uses a baffle plate that rotates under the pull of rainwater, so that it is in a state of shielding the cooling tank on sunny days to prevent debris from falling into the cooling tank and causing blockage. On rainy days, the cooling tank is exposed and the rainwater is guided into the interior of the cooling tank. The cooling and heat dissipation are achieved by using the heat exchange between the rainwater and the outdoor power distribution cabinet, thereby improving the active heat dissipation effect of the outdoor power distribution cabinet on rainy days.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Reference Figure 1-6This invention proposes a protective outdoor power distribution cabinet, including a cabinet body 1. The cabinet body 1 is composed of two side plates 11, a back plate 12, and two top and bottom plates 13. The two side plates 11, the back plate 12, and the two top and bottom plates 13 are connected and fixed to each other to form a cover structure with a rectangular cross-section. A rain guard 14 is provided on the top of one of the top and bottom plates 13. A main heat dissipation hole 111 and an auxiliary heat dissipation hole 112 are provided on one side of the outer wall of the side plate 11. The main heat dissipation hole 111 is located below the auxiliary heat dissipation hole 112. A groove 113 is provided on one side of the outer wall of the side plate 11 near the horizontal side of the main heat dissipation hole 111. A spring 114 is provided at the bottom of the groove 113. A linkage gear 115 is rotatably connected to the inside of the side plate 11 in a through state. A limit switch 116 is provided on the other side of the outer wall of one of the side plates 11. An outer rain guard component 2 and an inner heat dissipation component 3 are provided on the side plate 11. The outer rain shield assembly 2 includes a rain shield 21 that slides on one side of the outer wall of the side plate 11. Two external racks 211 and two external mating blocks 212 are symmetrically arranged on the outer wall of the rain shield 21 facing the side plate 11. The external racks 211 are located above the external mating blocks 212 and mesh with a linkage gear 115. The external mating blocks 212 are fixedly connected to the top of a spring 114. An air inlet 213 is provided on one side of the outer wall of the rain shield 21 near the two external racks 211, and an electromagnet 214 is embedded therein. An air intake hood 215 is provided on the outer wall of the side panel 11 away from the side plate 11, near the air intake port 213. Several air intake holes 2151 are evenly spaced at the bottom of the air intake hood 215. A rain collection hood 216 is provided on the outer wall of the rain shield 21 away from the side plate 11, near the upper part of the air intake hood 215. An outer edge plate 2161 is provided on the top outer edge of the rain collection hood 216, and two limiting sleeves 2162 are symmetrically arranged on the inner bottom of the rain collection hood 216. A [missing information - likely a design feature] is provided at the inner center of the inner bottom of the rain collection hood 216 near the limiting sleeves 2162. A fixed contact 2163 and a second spring 2164 are provided. The fixed contact 2163 is located inside the second spring 2164. A guide post 2165 is provided at the top of the second spring 2164. A moving contact 2166 is provided at the bottom of the guide post 2165, near the top of the fixed contact 2163. A metal block is embedded in the outer wall of one side of the side plate 11, which is magnetically attracted to the electromagnet 214 that has been energized and generated magnetism. The fixed contact 2163, the moving contact 2166, the electromagnet 214, and the external power supply constitute a circuit path. The structure can form a complete circuit structure. When the fixed contact 2163 and the moving contact 2166 are in contact, the circuit structure that was originally in a closed state becomes an open circuit structure. At this time, after the electromagnet 214 loses the power supply from the external power source, the electromagnet 214 is de-energized and loses its magnetism. The top of the guide post 2165 is provided with a pressure plate 2167, and a through hole is opened on one side of the outer wall of the rain cover 216 near the maximum moving height of the pressure plate 2167 to allow rainwater to drain slowly, so that the rainwater can drain slowly and thus the pressure plate 2167 can be reset. The internal heat dissipation assembly 3 includes an inner movable plate 31 that slides on the outer wall of the other side of the side plate 11. Two inner racks 311 are symmetrically arranged on the outer wall of the inner movable plate 31 facing the side plate 11. A matching groove is provided on the outer wall of the side plate 11, allowing the outer rack 211 and inner rack 311 to move vertically. Both the rain shield 21 and the inner movable plate 31 are in a dynamically sealed fit with the outer wall of the side plate 11. The matching groove ensures that the rain shield 21 and the inner movable plate 31 can move up and down along the outer wall of the side plate 11, and the dynamic seal ensures the sealing of the rain shield 21 and the inner movable plate 31 as they move along the side plate 11, preventing leaks. To prevent rainwater leakage and ensure the airtightness of the outdoor power distribution cabinet, the internal rack 311 and the linkage gear 115 mesh together. An active heat dissipation groove 312 and two passive heat dissipation grooves 313 are opened on one side of the outer wall of the inner moving plate 31 near the two internal racks 311. The active heat dissipation groove 312 is located between the two passive heat dissipation grooves 313. A fixed cover 314 is provided on the outer wall of the inner moving plate 31 away from the side plate 11 and near the outer side of the active heat dissipation groove 312. A fan 315 is provided on the inner side wall of the fixed cover 314. An abutment 316 is provided on the top of the fixed cover 314 near the position directly below the limit switch 116. To prevent rainwater from entering the outdoor electrical distribution cabinet during rainfall while simultaneously achieving heat dissipation, this embodiment utilizes the coordinated operation of the external rainproof component 2 and the internal heat dissipation component 3. This allows the outdoor electrical distribution cabinet to have a certain self-heating capacity on sunny days. The convection design ensures that air can pass through the cabinet for heat dissipation, meeting the heat dissipation needs of distribution cabinets with internally installed low-power electrical equipment. Furthermore, during rainy weather, the heat dissipation vents used for convection cooling are blocked, and the fan 315 is forcibly activated for active cooling, preventing heat from being effectively dissipated due to blocked vents. The weight of rainwater is fully utilized to activate the coordinated operation between the external rainproof component 2 and the internal heat dissipation component 3. Specifically, on sunny days… The rain shield 21 and the inner movable plate 31 are in a balanced state. At this time, the passive heat dissipation groove 313 and the main heat dissipation hole 111 on the inner movable plate 31 are on the same horizontal plane and are connected. The rain shield 21 blocks the auxiliary heat dissipation hole 112 and is located above the main heat dissipation hole 111. At this time, the auxiliary heat dissipation holes 112, which are mirrored on the two side plates 11, allow air to enter and exit the outdoor distribution cabinet in a convective state. The convective airflow is used to achieve passive heat dissipation of the outdoor distribution cabinet, maintain the stability of the internal temperature of the outdoor distribution cabinet, and prevent the electrical equipment installed inside from being damaged due to its height. In rainy weather, especially in strong convective heavy rainfall, as the rain falls, the rain collection cover 2... 16 collects rainwater. When the collection speed exceeds the discharge speed, the amount of rainwater in the rain collection cover 216 increases rapidly. Under the gravity of the rainwater, the rainwater pushes the pressure plate 2167 downward, and the spring 2164 is compressed. When the fixed contact 2163 and the moving contact 2166 contact, the circuit structure that was originally in a closed state becomes an open circuit structure. At this time, after the electromagnet 214 loses the power supply from the external power source, the electromagnet 214 is de-energized and loses its magnetism. After the rain shield 21 is no longer fixed, under the action of the rainwater and the gravity of the rain shield 21 itself, the rain shield 21 moves downward along the side plate 11. The rain shield 21 blocks the main heat dissipation hole 111, and the air inlet 213 and the auxiliary heat dissipation hole 112 overlap and connect. The rain shield 21 moves downward, and the outer rack 211 on the rain shield 21 moves downward synchronously. Through the meshing transmission of the outer rack 211 and the inner rack 311 with the linkage gear 115, the inner rack 311 pulls the inner moving plate 31 to move upward along the side plate 11. As the fixed cover 314 and the fan 315 move upward, when the fan 315 overlaps and connects with the auxiliary heat dissipation hole 112, the contact joint 316 contacts the limit switch 116. At this time, the power supply system in the outdoor power distribution cabinet supplies power to the fan 315. After the fan 315 is powered on, it works and draws the air outside the outdoor power distribution cabinet into the interior. The outside air enters the air intake cover 215 from bottom to top along the air intake hole 2151, effectively preventing rainwater from seeping in.

[0022] Example 2 Reference Figure 1-2 and Figure 7-9 Based on the above embodiments, this embodiment of the invention also proposes that a traction rack 2168 is provided on one side outer wall of the rain collection cover 216, and a plurality of electrical mounting brackets 121 are provided on one side outer wall of the back plate 12 near the two side plates 11 and at equal intervals in the vertical direction. A cooling groove 122 is provided on the top of the back plate 12, and a drain outlet 123 is provided on the other side outer wall of the back plate 12 near the bottom position. The drain outlet 123 and the cooling groove 122 are connected. Two symmetrical guide grooves 141 are formed on the top of the rain guard 14, and an arc groove 142 is embedded in the top of the rain guard 14 and located on the guide grooves 141. A baffle plate 143 is rotatably connected inside the arc groove 142. The arc groove 142 is connected to the cooling groove 122, and the inner circumferential surface of the arc groove 142 matches and fits the outer wall of the baffle plate 143. The connected structure allows rainwater to enter the arc groove 142 under the guidance of the guide grooves 141 and flow out through the arc groove. Rainwater enters the cooling tank 122 through the flow of rainwater within the cooling tank 122, achieving heat dissipation of the back panel 12 via heat exchange, thereby achieving heat dissipation of the distribution cabinet. The rotation of the baffle plate 143 within the arc groove 142 ensures the airtightness of the baffle plate 143 during its rotation. The baffle plate 143 consists of an inclined plate 1431, an inclined plate 1432, and a vertical plate 1433. The inclined plate 1431 and the inclined plate 1432 are fixed together on the same axis. The straight plate 1433 is located at the joint of the inclined plate 1431 and the inclined plate 1432, and is vertically connected. A traction gear 144 is provided at the axial end of the baffle plate 143. The traction gear 144 meshes with the traction rack 2168. The module and number of teeth between the traction gear 144 and the traction rack 2168 allow the traction gear 144 to rotate precisely at a certain angle corresponding to a specific distance the traction rack 2168 moves. This special design of the module and number of teeth enables the external rain shield to... After component 2 moves downward under the gravity of rainwater, the traction rack 2168 and traction gear 144 mesh to make the baffle plate 143 rotate and make the baffle plate 143 reach the designed angle state. Specifically, the inclined plate 1432 and the arc groove 142 form a 60-degree angle, the inclined plate 1431 is located inside the arc groove 142, and the gap between the vertical plate 1433 and the arc groove 142 allows rainwater to pass through. The rainwater flows downward along the inner wall of the cooling tank 122. To improve the active heat dissipation capability of the outdoor power distribution cabinet, in this embodiment, the baffle plate 143 rotates under the pull of rainwater, so that it is in a state of shielding the cooling tank 122 on sunny days, preventing debris from falling into the cooling tank 122 and causing blockage. On rainy days, the cooling tank 122 is exposed, and rainwater is guided into the interior of the cooling tank 122. The cooling effect is achieved by the heat exchange between the rainwater and the outdoor power distribution cabinet, thereby improving the active heat dissipation effect of the outdoor power distribution cabinet on rainy days. Specifically, on sunny days, the external rain shield component 2 is in a stable position. At this time, the tops of the first inclined plate 1431 and the second inclined plate 1432 coincide with the guide channel 141 on the same inclined plane. The baffle plate 143 shields the arc groove 142 and the cooling tank 122, preventing debris from falling in. On rainy days... After the outer rain shield assembly 2 moves downward, the traction rack 2168 moves downward synchronously. Through the meshing transmission between the traction rack 2168 and the traction gear 144, the traction rack 2168 pulls the traction gear 144 to rotate, and the traction gear 144 pulls the baffle plate 143 to rotate. Because the module and number of teeth on the traction rack 2168 and the traction gear 144 are designed, when the outer rain shield assembly 2 moves downward to the lowest position, the inclined plate 1432 on the baffle plate 143 forms a 60-degree angle with the arc groove 142. The inclined plate 1431 is located inside the arc groove 142. The gap between the vertical plate 1433 and the arc groove 142 allows rainwater to pass through. The rainwater flows downward along the inner wall of the cooling tank 122, and the flowing rainwater is used to dissipate heat from the outdoor power distribution cabinet.
