Abstract

This invention relates to a wall-mounted and floor-standing integrated distribution box, belonging to the field of distribution box technology. It includes a main body, a fixing component at the cable inlet and outlet, multiple fixing plates equally spaced within the fixing component, an opening / closing component at the heat dissipation vent, a sealing plate fixed to one side of the opening / closing component, and a heat dissipation component on the back of the main body, containing multiple heat dissipation plates evenly spaced. This invention uses multiple fixing plates evenly arranged circumferentially to form a ring-shaped clamping surface. The contact surface between the fixing plates and the cable is machined into a continuous sawtooth shape, forming multiple annular edges along the cable axis. This ring-shaped clamping transfers the axial tension generated by the cable's own weight to the box shell, alleviating the continuous pulling force on the terminals. Simultaneously, the sawtooth contact surface forms multiple labyrinthine sealing interfaces along the cable axis, which can, to a certain extent, prevent dust and moisture from entering the box through the gaps between the cable and the hole walls.

Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically to a wall-mounted and floor-standing integrated distribution box. Background Technology

[0002] This wall-mounted and floor-standing integrated distribution box features pre-drilled wall-mounting holes and an optional base for floor-standing installation. It integrates incoming line protection, power distribution, metering, leakage protection, and surge protection. The choice between wall-mounted or floor-standing options depends on site conditions. It is commonly used in low-voltage power distribution scenarios such as factories, buildings, construction sites, and transformer substations. The back of the box has wall-mounting holes, while a channel steel base is added for floor-standing use. Cable entry / exit holes are located at the bottom. As a terminal device in the power distribution network, this type of distribution box is compatible with low-voltage distribution nodes in smart grids. It provides bottom-level terminal power distribution support for large-scale power grid security, defense systems, and intelligent dispatching systems, receiving power from the upper-level transmission network, distributing and protecting power, and ensuring the stable operation of low-voltage equipment.

[0003] However, in existing wall-mounted and floor-mounted integrated distribution boxes, the incoming and outgoing cables are subject to their own weight. Especially when wall-mounted, the cables hang vertically downwards, which exerts a continuous axial tension on the terminals. When floor-mounted, the cables bend inside the base, creating lateral stress. Over time, this can cause terminal screws to loosen, contact resistance to increase, or even cables to come loose. Without securing the cables, the stress will directly affect the electrical connections. Furthermore, when wall-mounted, the back of the box is flush against the wall, and the rear ventilation openings are blocked, making it difficult for air to form effective convection at the back. In this case, the rear ventilation openings not only fail to dissipate heat but may also become a channel for moisture and dust from the wall to enter the box. When floor-mounted, the bottom of the box is supported and blocked by the base, obstructing airflow at the bottom ventilation openings. If the ventilation openings are kept open, some ventilation openings will be blocked or ineffective in both installation modes, reducing the effective heat dissipation area and hindering air convection within the box, leading to higher temperatures.

[0004] To address the aforementioned issues, there is an urgent need for innovative design of the existing integrated distribution box that can be installed both wall-mounted and floor-standing. Summary of the Invention

[0007] Preferably, the inner wall of the main body has a cavity that moves to cooperate with the heat dissipation plate. The inner wall of the cavity is fixedly connected to the second oil tank. The second oil tank is connected to the first oil tank through a hose. The knob rotates with the inner wall of the main body, and a friction damping engagement is formed between the knob and the inner wall of the main body. Under the drive of external force, the knob can rotate relative to the inner wall. After the external force is removed, the knob can be maintained in the corresponding position after rotation due to the friction damping effect.

[0008] Preferably, the fixing component includes a gear fixedly connected to the knob, the gear meshing with a gear ring, a rotating ring fixed to the inner wall of the gear ring, a plurality of guide rods slidably connected at equal angles inside the rotating ring, the bottom end of the guide rods being fixedly connected to a fixing plate, and a fixing ring slidably connected to a protrusion at the bottom end of the fixing plate.

[0009] Preferably, the rotating ring has a cavity that moves with the guide rod, and the fixed ring has a cavity that moves with the bottom protrusion of the fixed plate. The fixed ring is fixedly connected to the cavity in the inner wall of the main body.

[0010] Preferably, the opening and closing assembly includes a base fixed to the bottom of the main body, a slide rod slidably connected to the base, pull frames fixed to both ends of the slide rod, tension springs symmetrically fixed to the outer wall of the slide rod, and the base rotatably connected to the sealing plate.

[0011] Preferably, the base has sliding grooves on both sides, the sliding grooves are slidably connected to the sliding rod, and the sealing plate has two slots that cooperate with the pulling frame, and the slots are vertically distributed between them.

[0012] Preferably, one end of the tension spring is fixedly connected to the slide rod, the other end of the tension spring is fixedly connected to the base protrusion, the slide rod is fixedly connected to the first sliding rod, and the base protrusion is fixedly connected to the first oil tank.

[0013] Preferably, the heat dissipation assembly includes a push plate fixedly connected to the second sliding rod, the push plate is slidably connected to a movable frame, a plurality of rotating plates are rotatably connected at equal distances on one side of the movable frame, one side of the rotating plate is fixedly connected to a rotating shaft, and the rotating shaft is fixedly connected to the heat dissipation plate.

[0014] Preferably, both sides of the heat sink are fixed with rotating shafts, which are rotatably connected to the inner wall of the main body cavity, and the main body has a cavity that cooperates with the movable frame and the rotating plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses multiple fixing plates evenly arranged circumferentially to form a ring-shaped clamping surface. The contact surface between the fixing plates and the cable is processed into a continuous sawtooth shape, forming multiple annular edges along the cable axis. This ring-shaped clamping transfers the axial tension generated by the cable's own weight to the housing shell, alleviating the continuous pulling force on the terminals. This helps reduce the probability of problems such as terminal loosening, increased contact resistance, and overheating oxidation, improving the long-term reliability of electrical connections. At the same time, the sawtooth contact surface forms multiple labyrinth-like sealing interfaces along the cable axis, which can, to a certain extent, prevent dust and moisture from entering the housing through the gap between the cable and the hole wall, improving the protection level of the inlet hole and slowing down the rate of environmental corrosion of internal components.

[0016] 2. This invention uses the bottom sealing plate as a trigger source to synchronously drive the opening and closing of the back heat dissipation plate via hydraulic transmission. When the bottom sealing plate is switched to the closed state, it can block the path of dust and moisture accumulated inside the base to enter the box upwards through the ventilation opening, reducing the probability of the box being contaminated by the environment on the side of the base. At the same time, the back heat dissipation plate is switched to the open state, increasing the effective heat dissipation area by utilizing the space where the back is completely exposed when the box is placed on the ground, which helps to improve the heat dissipation efficiency inside the box, reduce the temperature rise under full load, and slow down the insulation aging rate of electrical components. When the back heat dissipation plate is switched to the closed state, it can prevent moisture, dust, and insects from entering the box through the ventilation openings that are blocked by the wall, and at the same time prevent the formation of airflow dead zones and condensation accumulation after the ventilation openings are blocked. At the same time, the bottom ventilation opening is opened, utilizing the bottom suspended space to organize air intake. Even when the back heat dissipation surface fails, a complete air convection path can still be constructed to ensure basic heat dissipation capacity and alleviate the heat dissipation pressure under wall-mounted conditions.

[0019] Please see Figures 1 to 9 This invention provides a technical solution: a wall-mounted and floor-standing integrated power distribution box, comprising a main body 1, with a cable inlet / outlet and a heat dissipation vent at the bottom of the main body 1, a knob 2 at the bottom of the main body 1, a fixing component at the cable inlet / outlet, multiple fixing plates 4 are equally spaced within the fixing component, and the fixing plate 4 is rotated by the fixing component to fix the cable, the contact surface between the fixing plate 4 and the cable is serrated, an opening / closing component at the heat dissipation vent, a sealing plate 6 is fixed on one side of the opening / closing component, and the opening / closing component moves the sealing plate 6 to open and close the heat dissipation vent, a first sliding rod 7 is fixed within the opening / closing component, and a first oil tank 8 is slidably connected to the outer wall of the first sliding rod 7, a heat dissipation component is provided on the back of the main body 1, multiple heat dissipation plates 12 are equally spaced within the heat dissipation component, and the heat dissipation component rotates the heat dissipation plates 12 to switch the heat dissipation state of the back of the main body 1, a second oil tank 9 is provided on one side of the heat dissipation component, and a second sliding rod 10 is slidably connected within the second oil tank 9.

[0020] In practice, the bottom of the main body 1 is equipped with cable inlet / outlet and heat dissipation vent. Rotating the knob 2 at the bottom of the main body 1 can drive the fixing component to move multiple fixing plates 4 arranged at equal angles in a centripetal motion. The cable is clamped and fixed by the sawtooth contact surface of the fixing plate 4. The operation of the opening and closing component can drive the sealing plate 6 to move, realizing the opening and closing of the heat dissipation vent at the bottom of the main body 1. The opening and closing component simultaneously drives the first sliding rod 7 to slide within the first oil tank 8. Through the oil transmission, the second sliding rod 10 inside the second oil tank 9 is displaced, thereby driving the heat dissipation component and causing multiple heat dissipation plates 12 in the heat dissipation component on the back of the main body 1 to rotate, thus completing the linkage switching of the heat dissipation on / off state of the back of the main body 1.

[0021] As a further embodiment of the present invention, the inner wall of the main body 1 is provided with a cavity that moves in conjunction with the heat sink 12. The inner wall of the cavity is fixedly connected to the second oil tank 9. The second oil tank 9 is connected to the first oil tank 8 through a hose. The knob 2 is rotated in conjunction with the inner wall of the main body 1, and a friction damping fit is formed between the knob 2 and the inner wall of the main body 1. Under the drive of external force, the knob 2 can rotate relative to the inner wall. After the external force is removed, the knob 2 can be maintained in the corresponding position after rotation due to the friction damping effect.

[0022] In specific implementation, this structure has a cavity in the inner wall of the main body 1 for the heat sink 12 to move. The inner wall of the cavity is fixed with a second oil tank 9, which is connected to the first oil tank 8 through a hose, forming a hydraulic oil circuit structure that can be linked and transmitted, thereby realizing the linkage switching of the working state of the heat sink 12. At the same time, the knob 2 rotates with the inner wall of the main body 1 to form a friction damping structure. Under the action of external force, the knob 2 can rotate relative to the inner wall of the main body 1 to adjust the working state of the cable clamping structure. After the external force is removed, the current rotation position can be stably maintained by the damping friction force, realizing stepless positioning. The stability of the clamping adjustment state can be guaranteed without the need for an additional locking structure.

[0023] As a further embodiment of the present invention, the fixing component includes a gear 301 fixedly connected to the knob 2, the gear 301 meshing with a gear ring 302, a rotating ring 303 fixedly fixed to the inner wall of the gear ring 302, a plurality of guide rods 304 slidably connected at equal angles inside the rotating ring 303, the bottom end of the guide rods 304 being fixedly connected to the fixing plate 4, and a fixing ring 305 slidably connected to the bottom protrusion of the fixing plate 4.

[0024] In practice, the knob 2 drives the gear 301 to rotate, and the gear 301 meshes with and drives the gear ring 302 to rotate synchronously, so that the rotating ring 303 inside the gear ring 302 rotates with it. The rotating ring 303 drives multiple guide rods 304 arranged at equal angles to slide synchronously through the internal contour. The guide rods 304 drive the fixed plate 4 fixed at the bottom to move. The protrusion at the bottom of the fixed plate 4 slides along the fixed ring 305 to limit the movement, thereby realizing that multiple sets of fixed plates 4 synchronously converge towards the center or open outward, completing the adaptive circumferential clamping and fixing of cables of different diameters, ensuring that the cable clamping force is uniform and the fixing is reliable.

[0025] As a further embodiment of the present invention, the rotating ring 303 has a cavity that moves in conjunction with the guide rod 304, and the fixing ring 305 has a cavity that moves in conjunction with the bottom protrusion of the fixing plate 4. The fixing ring 305 is fixedly connected to the cavity on the inner wall of the main body 1.

[0026] In specific implementation, the rotating ring 303 has a cavity for the guide rod 304 to move, thereby converting the rotational motion of the rotating ring 303 into the radial movement of the guide rod 304. The fixed ring 305 has a cavity adapted to the sliding of the bottom protrusion of the fixed plate 4, which limits the radial movement of the fixed plate 4. The fixed ring 305 is fixed to the cavity position of the inner wall of the main body 1, realizing the positioning and installation of the overall fixed assembly. This ensures that the guide rod 304 can only move the fixed plate 4 radially to converge and open, thus ensuring the motion accuracy of the multiple fixed plates 4 in the process of clamping the cable.

[0027] As a further embodiment of the present invention, the opening and closing assembly includes a base 501 fixed to the bottom end of the main body 1, a slide rod 503 slidably connected to the base 501, a pull frame 504 fixed at both ends of the slide rod 503, a tension spring 505 symmetrically fixed to the outer wall of the slide rod 503, and the base 501 rotatably connected to the sealing plate 6.

[0028] In specific implementation, the base 501 is fixedly installed at the bottom of the main body 1, the slide rod 503 is slidably engaged with the base 501, the two ends of the slide rod 503 are fixedly connected with the pull frame 504, and the outer side of the slide rod 503 is symmetrically equipped with tension springs 505. The base 501 is rotatably connected to the sealing plate 6. By operating the pull frame 504, the slide rod 503 can be driven to slide on the base 501 and the tension spring 505 can be stretched and deformed. After the pull frame 504 is released, the slide rod 503 can be reset by the restoring force of the tension spring 505, thereby locking the flipped sealing plate 6, completing the work position switching of the sealing plate 6, and realizing the opening and closing control of the bottom heat dissipation port.

[0029] As a further embodiment of the present invention, the base 501 has sliding grooves 502 on both sides, the sliding grooves 502 are slidably connected to the sliding rod 503, and the sealing plate 6 has two slots that cooperate with the pulling frame 504, and the slots are vertically distributed between them.

[0030] In specific implementation, sliding grooves 502 are opened on both sides of the base 501. The sliding grooves 502 and the sliding rod 503 slide together, providing guidance and constraint for the reciprocating sliding of the sliding rod 503. Two vertically distributed slots are provided on the sealing plate 6 and are adapted to the pull frame 504. After rotating the sealing plate 6 to switch the working position, the sliding rod 503 can be inserted into the corresponding slot under the action of the return force of the tension spring 505, thereby realizing the limit locking of the two working positions of the sealing plate 6, which correspond to the two working states of the heat dissipation port at the bottom of the main body 1 being closed and open, respectively.

[0031] As a further embodiment of the present invention, one end of the tension spring 505 is fixedly connected to the slide rod 503, the other end of the tension spring 505 is fixedly connected to the protrusion of the base 501, the slide rod 503 is fixedly connected to the first sliding rod 7, and the protrusion at the base 501 is fixedly connected to the first oil tank 8.

[0032] In specific implementation, one end of the tension spring 505 is fixed to the slide rod 503, and the other end is connected to the protrusion of the base 501 to provide a reset tension for the slide rod 503. The slide rod 503 is fixedly connected to the first sliding rod 7. The protrusion of the base 501 provides fixed support for the first oil tank 8. When the pulling frame 504 drives the slide rod 503 to slide, the tension spring 505 can deform and accumulate elastic force, and the first sliding rod 7 can be driven to make a limited movement inside the first oil tank 8 at the same time, thereby outputting linear motion and providing motion input for the subsequent hydraulic transmission to realize the linkage switching of the heat sink 12.

[0033] As a further embodiment of the present invention, the heat dissipation assembly includes a push plate 111 fixedly connected to the second sliding rod 10, a movable frame 112 slidably connected to the push plate 111, a plurality of rotating plates 113 rotatably connected at equal distances on one side of the movable frame 112, a rotating shaft 114 fixedly connected to one side of the rotating plate 113, and the rotating shaft 114 fixedly connected to the heat dissipation plate 12.

[0034] In specific implementation, the push plate 111, which is fixed to the second sliding rod 10, moves linearly back and forth with the second sliding rod 10. The push plate 111 slides with the moving frame 112, thereby driving the moving frame 112 to generate displacement. The moving frame 112 drives multiple rotating plates 113 connected to it to rotate. The rotating plates 113 drive the heat sink 12 to deflect synchronously through the rotating shaft 114, thereby converting the linear motion output by the second sliding rod 10 into the rotational motion of the heat sink 12, realizing the switching between the opening and closing of the heat sink on the back of the main body 1.

[0035] As a further embodiment of the present invention, the heat sink 12 is fixed with rotating shafts 114 on both sides, the rotating shafts 114 are rotatably connected to the inner wall of the cavity of the main body 1, and the main body 1 has a cavity that cooperates with the movable frame 112 and the rotating plate 113.

[0036] In specific implementation, rotating shafts 114 are fixed to both sides of the heat sink 12. The rotating shafts 114 rotate with the inner wall of the cavity of the main body 1 to form a rotational support for the heat sink 12. The main body 1 has a cavity inside that allows the movable frame 112 and the rotating plate 113 to move, providing clearance for the linear sliding of the movable frame 112 and the rotational swing of the rotating plate 113, so that the transmission motion can be smoothly transmitted to the rotating shaft 114, driving the heat sink 12 to complete the deflection action, thereby realizing the on / off switching of the heat sink on the back of the main body 1.

[0037] Working principle: When using this wall-mounted and floor-standing integrated distribution box, after the cable is connected to the main body 1 and the electrical connection is completed, it passes through the cable inlet / outlet hole at the bottom of the main body 1. When the knob 2 is turned (the knob 2 and the shaft hole on the inner wall of the main body 1 are damped friction fit, and the rotation angle is self-locked by the static friction of the contact surface, and the position can be maintained at any angle within the rotation stroke), the gear 301 fixed on the same axis rotates synchronously. The gear 301 meshes with the gear 301 and drives the gear ring 302 to rotate on the same axis, which in turn drives the rotating ring 303 fixed to the gear ring 302 to rotate synchronously. The rotating ring 303 has a cavity that moves with the guide rod 304. The guide rod 304 is fixedly connected to the fixing plate 4, so that the rotating ring 303 drives the fixing plate 4 to slide along the cavity opened by the rotating ring 303. At this time, the protrusion at the bottom of the fixing plate 4 is fixed. The fixed ring 305 slides within the cavity, causing multiple fixing plates 4 to move synchronously towards the center along the radial cavity of the fixed ring 305, forming a ring-shaped clamping of the cable. The contact surface between the fixing plate 4 and the cable has a sawtooth structure, which can adapt to cables of different diameters. The clamping also forms multiple sealing interfaces, and the circumferential force on the cable is relatively uniform, which can reduce the risk of local stress concentration, uneven wear and displacement of the cable, and help maintain the connection stability between the cable and the terminal. The sawtooth clamping surface can increase the friction of the contact surface, improve the axial tensile force of the cable, alleviate the continuous pulling effect of the cable's own weight on the terminal, and reduce the probability of terminal loosening and increased contact resistance. On the other hand, the multiple sawtooth edges can form a labyrinth seal, which to a certain extent prevents dust and moisture from entering the box along the cable surface, thus achieving the dual function of mechanical fixation and protective sealing. After the cables are fixed, determine the installation method: wall-mounted or floor-mounted. If floor-mounted, pull the pull bracket 504. The movement of the pull bracket 504 causes the slide rod 503, which is fixed to the pull bracket 504, to slide in the slide groove 502. At this time, the tension spring 505 between the base 501 and the slide rod 503 is stretched. Rotate the sealing plate 6 to a position perpendicular to the base 501. Then release the pull bracket 504. The slide rod 503 slides inward under the return force of the tension spring 505 and gets into the corresponding limiting groove of the sealing plate 6, thus locking the position of the sealing plate 6. At this time, the heat dissipation vent at the bottom of the main body 1 is sealed by the sealing plate 6. When the slide rod 503 moves into the slot where the sealing plate 6 is in a vertical position, it drives the first slide rod 7, which is fixed to it, to move within the first oil tank 8. The end of the first slide rod 7 has a piston structure, which slides within the cavity of the first oil tank 8 to compress the hydraulic oil in the cavity. The hydraulic oil is then transported to the second oil tank 9 through a connecting hose, pushing the piston at the end of the second slide rod 10, causing the second slide rod 10 to extend outward along the cavity of the second oil tank 9. The movement of the second slide rod 10 drives the push plate 111, which is fixed to it, to move synchronously. Since the push plate 111 is slidably connected to the moving frame 112, and the moving frame 112 is rotatably connected to the rotating plate 113, the movement of the push plate 111 pushes the moving frame 112. When the mobile frame 112 moves, it slides on the outer wall of the push plate 111, which causes the rotating plate 113 to rotate. The rotating plate 113 is fixedly connected to the heat sink 12 through the rotating shaft 114. The rotating plate 113 drives the heat sink 12 to deflect, so that the heat sink on the back of the main body 1 is switched to the open state. When the body is on the ground, the bottom ventilation is closed, which can block the path of dust and moisture inside the base to enter the box through the ventilation. This helps to maintain a clean and dry operating environment inside the box. At the same time, the back ventilation is opened. When the body is installed on the ground, the back of the box is separated from the wall and has effective heat dissipation conditions. After opening, the effective heat dissipation area of ​​the back of the box can be increased, which helps to improve the heat dissipation efficiency inside the box, reduce the temperature rise during full load operation, and slow down the insulation aging rate of electrical components. When wall-mounted installation is selected, pull the pull bracket 504 to release the limit of the sliding rod 503 on the sealing plate 6, flip the sealing plate 6 to a position parallel to the base 501, and after releasing the pull bracket 504, the sliding rod 503 resets under the action of the tension spring 505 and locks into the corresponding slot of the sealing plate 6. At this time, the heat dissipation vent at the bottom of the main body 1 is switched to the open state. At the same time, the sliding rod 503 drives the first sliding rod 7 to reset outward, a negative pressure is formed in the first oil tank 8, and the hydraulic oil in the second oil tank 9 flows back along the hose. The second sliding rod 10 drives the push plate 111 to retract, and the moving bracket 11 moves back to the starting position. 2. The rotating plate 113 drives the rotating shaft 114 to rotate in the opposite direction, causing the back heat sink 12 to deflect and reset in the opposite direction, sealing the heat sink vent on the back of the main body 1. When wall-mounted, the back of the cabinet is close to the wall. Sealing the back vent can prevent moisture, dust, and insects from entering the cabinet through the vent. At the same time, it can prevent the back vent from being blocked by the wall, thus preventing the formation of a dead air zone and the accumulation of condensation, and protecting the internal electrical components from corrosion. After opening the bottom vent, in the case of failure of the back heat sink, the bottom suspended space is fully utilized to organize airflow, ensure basic heat dissipation capacity, and alleviate the heat dissipation pressure under wall-mounted conditions.
