Description

Technical Field

[0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to an outdoor rainproof and heat-dissipating power distribution cabinet. Background Art

[0002] If existing power distribution cabinets are placed outdoors, they must be dustproof and rainproof. For example, CN210693065U discloses a dustproof and heat-dissipating power distribution cabinet, which includes a cabinet body with a plurality of heat dissipation holes arranged in a matrix on the cabinet sidewalls. A downwardly curved arc shield is fixed to the cabinet outer wall above each heat dissipation hole. The heat dissipation holes are strip-shaped and arranged horizontally. Although this device can use the arc shield to block the heat dissipation holes to prevent rainwater from entering the cabinet body during rain, the presence of the arc shield will affect the heat dissipation effect of the heat dissipation holes. At the same time, the existing rainproof top cover is connected to the top of the cabinet body when in use. This relatively closed setting will affect the overall heat dissipation effect of the power distribution cabinet. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0038] See also Figure 1-4As shown, the present invention is an outdoor rainproof and heat-dissipating power distribution cabinet, including a cabinet body, which includes a cubic frame 1, and the cubic frame 1 is fixed with a front plate 11 and three side plates 10 in sequence along its peripheral side walls. A door opening is provided on the front plate 11, and a cabinet door 111 is hingedly installed on one side of the door opening; at the same time, a heat dissipation hole 101 is provided on the side plate 10, and the outer wall of the side plate 10 located at the heat dissipation hole 101 is provided with a "U"-shaped water retaining edge A102, and also includes a rain shield 12 hingedly connected to the bottom of the water retaining edge A102, and the four corner sides of the rectangular frame A at the top of the cubic frame 1 are provided with mounting plates A14, and a telescopic structure 15 is provided on the mounting plate A14, and a top cover 3 is connected to the end of the telescopic structure 15, and a guide wheel seat 13 is provided near the inner wall of the rectangular frame A of the side plate 10, and the guide wheel seat 13 is installed The waist-shaped wheel 131 and the inner top side surface of the top cover 3 are provided with three downward-extending connecting rods 30, and the bottom end of the connecting rod 30 is connected to the traction rope A130, and one end of the traction rope A130 passes through the waist-shaped wheel 131 and is connected to the top position of the inner wall of the rain shield 12; when the telescopic structure 15 drives the top cover 3 to complete the maximum upward movement, the bottom end of the connecting rod 30 is lower than the waist-shaped wheel A131, and then in the above, when the telescopic structure 15 is controlled to extend, the top cover 3 moves upward, and at this time, under the action of the traction rope A130 and the self-gravity of the rain shield 12, the rain shield 12 flips outward along the hinge, and a gap A is formed between the bottom end of the top cover 3 and the top of the cabinet, and the heat dissipation hole 101 is in an open state. The formed gap A and the heat dissipation hole 101 can be used for heat dissipation.

[0039] At the same time, when the telescopic structure 15 is controlled to shrink, under the action of the traction rope A130, the rain shield 12 flips inward along the hinge until it fits on the water retaining edge A102. A waterproof edge 31 extends downward on the peripheral side of the top cover 3, and at this time, the bottom end of the waterproof edge 31 is higher than the top of the front plate 11 and the side plate 10; at the same time, in order to improve the rainproof and waterproof effect, connecting plates 120 pivotally connected to the water retaining edge A102 are provided on both sides of the inner wall of the rain shield 12, and a "U"-shaped water retaining edge B121 is provided on the edge side of the inner wall of the rain shield 12; a water retaining convex edge 103 flipped outward is provided on the outer side of the water retaining edge A102.

[0040] It should be noted that in order to facilitate the implementation of intelligent control in the above, the telescopic structure 15 uses a telescopic motor or a telescopic cylinder, and the telescopic structure 15 is connected to a controller, and the controller is connected to a raindrop sensor. When the raindrop sensor detects rain, the controller controls the telescopic structure 15 to retract; when the raindrop sensor detects no rain, the controller controls the telescopic structure 15 to extend.

[0041] In order to facilitate the control of the rain shield 12 after the top is turned down, as shown in FIG. Figure 5-6That is to say, when in use, it is necessary to control the telescopic structure 15 to extend, and it is also necessary to control the rain shield 12 to continue to flip along the hinge. The present invention installs a connecting member 6 that is telescopic in the vertical direction on the inner wall surface of the rain shield 12. The connecting member 6 includes at least two fixed blocks 61 installed on the rain shield 12, and a guide rod 62 that movably passes through the fixed block 61. Both ends of the guide rod 62 are connected to the limit plate 63. The limit plate 63 located at the top of the guide rod 62 is connected to the end of the traction rope A130, and a locking bolt A64 is provided on any fixed block 61; that is, when in use, when it is necessary to control the rain shield 12 to continue to flip along the hinge, the locking bolt A64 is controlled to loosen, and the guide rod 62 is controlled to move along its axial direction toward the end close to the traction rope A130.

[0042] It is understandable that, in order to facilitate the control of the top cover 3 moving downward, at this time, in order to facilitate the control of the rain shield 12, it is close to the water retaining edge A102, such as Figure 8-10 At this time, a baffle 32 is rotatably connected to the inner wall of the waterproof edge 31 opposite the side panel 10 through a rotating column, and the bottom end of the baffle 32 is connected to an extension plate 321 extending horizontally to one side, and the end of the extension plate 321 is threadedly connected to a locking bolt B33, and a washer 331 passes through the locking bolt B33; when protecting from rain, the end of the locking bolt B33 abuts against the outer wall of the rain shield 12, and when the baffle 32 is retracted, the washer 331 abuts against the outer wall of the waterproof edge 31.

[0043] In one possible implementation, Figure 11-12When the telescopic structure 15 includes an inner sleeve and an outer sleeve that are sealed and sleeved with each other, in order to facilitate the control of the telescopic structure 15 to perform synchronous telescopic expansion and contraction, the four telescopic structures 15 of the present invention are all connected to an air supply pipeline 16 through a hose. The air supply pipeline 16 is connected to an air supply pipe A17, and the end of the air supply pipe A17 is connected to a joint structure 18; the joint structure 18 includes a pipe body A180, one end of the pipe body A180 is connected to the air supply pipe A17, and a convex ring 181 and a convex ring B1 are provided on one side of the pipe body A180 away from the air supply pipe A17. 85; The side of the convex ring 181 close to the convex ring B185 is connected to the porous plate 183 through a spring A182, and the side of the porous plate 183 close to the convex ring B185 is provided with a plug 184; the convex ring B185 is provided with an air vent A1851 that cooperates with the plug 184; the side of the convex ring B185 away from the convex ring 181 is connected to the movable iron ring 187 through a spring B186, and the outer side of the movable iron ring 187 is provided with a sealing layer A1871; it also includes an air supply pipe B188 connected to the air supply device, and the air outlet of the air supply pipe B188 The end is connected to an electromagnet ring 189 that slides along the inner wall of the tube body A180, and a sealing layer B1891 that is sealed with the sealing layer A1871 is set on the outside of the electromagnet ring 189, that is, when in use, the air supply device is used to facilitate the introduction of air into the four telescopic structures 15, thereby prompting the four telescopic structures 15 to complete the synchronous extension; and through the setting of the movable iron ring 187 and the electromagnet ring 189, it is convenient to control the movable iron ring 187 and the electromagnet ring 189 to seal and dock when in use, so that the operator can carry the air supply when in use. The air supply device moves, thereby facilitating the operation of multiple distribution cabinets located in the outside world and controlling the extension of the telescopic structure 15 in the corresponding distribution cabinet; similarly, in order to facilitate the air supply, the air supply device provided in the present invention uses an air pump or an air pump and other devices; at the same time, the present invention uses the spring A182, the porous plate 183, the plug 184 and the air vent A1851 to facilitate the plug 184 to block the air vent A1851 to form a seal when the air supply device is stopped for air supply, thereby preventing gas from overflowing from the telescopic structure 15.

[0044] Specifically, such as Figure 11 and 13The air supply pipe 17 provided by the present invention is connected to the exhaust pipe 170 on one side, and the end of the exhaust pipe 170 is connected to the exhaust control structure 19; the exhaust control structure 19 includes a pipe body B190, one end of the pipe body B190 is connected to the exhaust pipe 170, and the other end is provided with an end plate 1901; a partition 191 is provided in the pipe body B190, and a vent hole B1910 is provided on the partition 191. The side of the partition 191 away from the exhaust pipe 170 is connected to a spring C193 that moves along the inner wall of the pipe body B190. The movable plate A194 is connected to a push rod 1941 on one side, and a sealing plate 1942 that matches the air vent B1910 is connected to the end of the push rod 1941. A frustum column 1943 that passes through the air vent B1910 is connected to one side of the sealing plate 1942. An adjusting bolt 197 is threadedly connected to the end plate 1901, and the end of the adjusting bolt 197 abuts against one side of a movable plate B196. One side of the movable plate B196 is connected to at least two guide columns 19 that pass through the end plate 1901. 8; A spring D195 is connected between the movable plate B196 and the movable plate A194, and a limit ring 1902 is provided on the inner wall of the tube body B190 between the movable plate B196 and the movable plate A194; at least two exhaust holes 192 are provided on the side wall of the tube body B190 between the movable plate A194 and the partition 191, and an air whistle 1921 is installed at one of the exhaust holes 192. When in use, the exhaust control structure 19 is used to control the exhaust control structure 19. When exhausting, loosen the adjusting bolt 197, and the sealing plate 1942 is controlled to separate from the movable plate A194 under the action of air pressure. At this time, the gas in the telescopic structure 15 is exhausted through the exhaust control structure 19, and the gas makes a sound when passing through the whistle 1921. At the same time, the present invention utilizes the double spring action of spring D195 and spring C193, which makes it convenient to automatically push open the sealing plate 1942 for exhaust when the air pressure is high, so as to avoid damage to the telescopic structure 15 due to excessive internal air pressure.

[0045] At the same time, the rectangular frame B at the bottom of the cubic frame 1 of the present invention is connected to the bottom plate 2, as shown in FIG. Figure 5 and 7, a rectangular hole 20 is opened in the middle of the bottom plate 2, and T-shaped guide columns 24 are provided at the four corners of the upper surface of the bottom plate 2 at the rectangular hole 20, and a cover plate 23 is also included to cover the rectangular hole 20; the T-shaped guide columns 24 are movable through the cover plate 23; a pair of traction ropes B22 are connected to both ends of the cover plate 23, and the ends of the traction ropes B22 are connected to the inner wall of the rain shield 12; a horizontally extending cross bar 105 is fixed to the inner wall of the side plate 10 at the bottom end of the heat dissipation hole 101, and a waist-shaped wheel B is provided at the end of the cross bar 105. The traction rope B22 passes through the waist-shaped wheel B, and then when the rain shield 12 is flipped outward in use, the cover plate 23 is driven to detach from the upper surface of the bottom plate 2 under the action of the traction rope B22. At this time, air can pass through the rectangular hole 20 and then enter the interior of the cabinet through the gap between the cover plate 23 and the bottom plate 2, thereby improving the overall heat dissipation effect; at the same time, the setting of the T-shaped guide columns 24 makes it convenient to control the movement of the cover plate 23 in the vertical direction.

[0046] Based on the above, since the rain shield 12 needs to complete a 180° flip, in order to limit the movement of the cover 23 during use, the rain shield 12 is controlled to continue to flip, such as Figure 5 and 7 A connecting structure 25 connected to the traction rope B22 is provided on the inner wall of the rain shield 12, and the connecting structure 25 includes a cylinder A250 with a port facing downward. The bottom side of the cylinder A250 is connected to a movable block A254 that moves along the inner wall of the cylinder A250 through a spring E253, and the end of the movable block A254 is connected to the movable block B256 through a spring rope 255, and the end of the movable block B256 is connected to the traction rope B22; the inner wall of the cylinder A250 is provided with a limiting convex ring A252 and a limiting convex ring B251 that respectively limit the movement of the movable block A254 and the movable block B256. After the control cover 23 moves upward and abuts against the T-shaped guide column 24, the rain shield 12 continues to be controlled to flip over. In the present invention, the spring E253 and the spring rope 255 are completely extended.

[0047] What you need to know is that Figure 14 、 16-17. After the telescopic structure 15 is controlled to extend, the end of the telescopic structure 15 is used to press against the inner top side of the top cover 3 to support the top cover 3, so as to prevent the telescopic structure 15 from being deflated and causing the top cover to always move downward under the action of its gravity. The rectangular frames A on both sides are connected to the mounting plates B53. The bottom side of the mounting plate B53 is connected to the cylinder B5 with the port facing upward. The cylinder B5 is penetrated by a vertical rod A50 whose top is movable and passes through the mounting plate B53. A mounting convex ring 502 is provided on the outer side of the vertical rod A50. A spring is connected between the mounting convex ring 502 and the bottom side of the cylinder B5. F52; two through holes A501 are set in the bottom end gap of the vertical rod A50, and a through hole B51 is set on the cylinder B5 in a concentric structure with the through hole A501. That is, after the telescopic structure 15 is controlled to extend and drive the top cover 3 to move upward, the vertical rod A50 is controlled to move upward and supported on the inner top side surface of the top cover 3 under the action of the spring F52. At the same time, a guide sleeve that cooperates with the vertical rod A50 is set on the inner top side surface of the top cover 3, and the vertical rod A50 is inserted into the guide. At this time, a pin rod is controlled to be inserted into the through hole B51 and the through hole A501, and then the vertical rod A50 is used to support the top cover 3.

[0048] Based on the above, in order to facilitate the control of the pin rod inserted into the through hole B51, or the pin rod is pulled out from the through hole B51, as shown in FIG. Figure 15 In the present invention, a horizontally arranged rod sleeve 43 is connected to the bottom side of the rectangular frame A on both sides through a suspension rod 44, a horizontal rod 40 is arranged in the rod sleeve 43, the end of the horizontal rod 40 is connected to the vertical rod B41, the top of the two vertical rods B41 is connected to the horizontally arranged operating rod 4, and a pin rod A42 is arranged on one side of the operating rod 4 to be inserted into the through hole B51 and the through hole A501; rectangular openings 431 are provided on the opposite sides of the two rod sleeves 43 along the length direction, one side of the horizontal rod 40 is connected to a connecting block 401 that passes through the rectangular opening 431, the end of the connecting block 401 is connected to a vertically arranged vertical rod C402, and the top of the vertical rod C402 is connected to a pin rod A42 that is inserted into the through hole B51. and the pin rod B403 in the through hole A501, the radii of the through hole B51, the through hole A501, the pin rod B403 and the pin rod A42 are r1, r2, r3 and r4 respectively, r3 and r4 are both smaller than r1, r3 and r4 are both smaller than r2; then based on the above, the operating rod 4 is used to control the cross bar 40 to extend and retract along the axial direction of the rod sleeve 43 in the rod sleeve 43, thereby completing the control of the pin rod A42 and the pin rod B403 to move in the horizontal direction, thereby conveniently controlling the pin rod B403 and the pin rod A42 to be inserted into the through hole B51 and the through hole A501, or inserting and pulling the pin rod B403 and the pin rod A42 out of the through hole B51 and the through hole A501 during use.
