Description

Technical Field

[0001] The invention belongs to the technical field of distribution boxes, and in particular relates to an outdoor distribution box. Background Art

[0002] A distribution box is a device used to distribute electricity. It usually includes a main distribution box and a distribution box, both of which are equipped with various electrical components. However, when repairing the inside of a distribution box, maintenance personnel may face space limitations, which restricts operations and the use of tools. In addition, the complex connection of electrical components leads to difficulties in further compressing the space.

[0003] In order to solve the above problems, the distribution box in the prior art often attempts to increase the internal operating space for easy maintenance. For example, a distribution box is disclosed in the Chinese utility model patent with announcement number CN221900404U. The device is provided with a rectangular through groove in the center of the top of the box body, and then the top plate and the mounting plate can pass through the rectangular through groove and be inserted into the interior of the box body. When the staff needs maintenance, they can hold the handle upwards to drive the electrical components installed on the mounting plate to be quickly pulled out, thereby increasing the operating space of the staff and improving the maintenance efficiency.

[0004] However, when in use, the device expands the operating space for maintenance by moving electrical components, and the cable length and wiring method need to be specially designed so that it can move freely with the mounting plate without being damaged. This may increase the complexity of design and installation, and frequent pulling and pulling may affect the stability and reliability of the electrical connection and increase the risk of failure. Summary of the invention

[0005] The object of the present invention is to provide an outdoor distribution box which can expand the operating space during maintenance without moving the internal electrical components.

[0006] The technical solution adopted by the present invention to solve the above problem is: an outdoor distribution box, comprising: An electrical component mounting frame, wherein a movable box is sleeved on the electrical component mounting frame; A space adjustment component includes a screw assembly rotatably connected to an electrical component mounting frame, a threaded block threadedly connected to the screw assembly, a connecting rod hinged between the threaded block and a movable box through a hinge, and a motor for driving the screw assembly to rotate.

[0007] Among them, the space adjustment component can control the movable box to move to both sides when the internal space of the distribution box needs to be expanded, and no electrical components are set on the movable box itself, avoiding any movement of electrical components during the process of expanding the space, thereby reducing the risk of failure.

[0008] The movable box and the electrical component mounting frame adopt a sleeve structure to form an independent functional module. During maintenance, only the movable box can be disassembled or replaced as a whole, without the need to inspect the internal circuits item by item, which significantly improves the convenience of maintenance (for example, the box module can be directly replaced when the waterproof sealing ring is damaged).

[0009] The space adjustment component is precisely controlled by the motor-driven displacement, and the movable box can form a progressive anti-accidental touch barrier when it is expanded. For example, when repairing in heavy rain, the expanded box can form a temporary rain shelter structure to reduce the risk of water ingress to live parts. This feature is particularly important in outdoor scenes.

[0010] A further preferred technical solution is that the screw rod assembly is a bidirectional screw rod, and the threaded blocks are provided in two groups, which are respectively threadedly connected to the forward and reverse threads of the bidirectional screw rod.

[0011] A further preferred technical solution is that two groups of bidirectional screw rods are arranged, respectively arranged on the upper and lower sides of the electrical component mounting frame, the motor is coaxially fixedly connected to one end of the lower bidirectional screw rod, one end of the two groups of bidirectional screw rods are coaxially fixedly connected with transmission gears, and the two groups of transmission gears are connected by a transmission toothed belt.

[0012] A further preferred technical solution is that: a guide groove is provided on the electrical component mounting frame, a guide block installed in the guide groove is provided on the movable box, and the guide block is slidably connected to the guide groove.

[0013] A further preferred technical solution is that a support leg is fixedly connected to the bottom of the electrical component mounting rack.

[0014] A further preferred technical solution is that a plurality of strip-shaped heat dissipation slots are provided on the side of the movable box.

[0015] A further preferred technical solution is that: a strip groove is provided at the bottom of the movable box, and the supporting legs are installed in the strip groove.

[0016] A further preferred technical solution is that a box door is hingedly connected to the front end of the movable box via a hinge.

[0017] A further preferred technical solution is that a sealing gasket is provided at a position on the movable box that is movably connected to the surface of the electrical component mounting frame.

[0018] A further preferred technical solution is that a shielding plate is fixedly connected to the top of the electrical component mounting rack via a bracket.

[0019] In summary, the present invention has the following benefits: 1. The present invention starts the motor and utilizes the transmission cooperation between the transmission gear and the transmission belt to drive two sets of bidirectional screws to rotate in the same direction at the same time. The rotation of the bidirectional screw drives the two sets of threaded blocks threadedly connected thereto to move toward each other, and under the cooperation of the hinged action between the threaded blocks and the movable box and the connecting rod, the two sets of movable boxes can be pushed to move to both sides of the electrical component mounting frame, thereby increasing the space size inside the distribution box for the convenience of maintenance by operators.

[0020] 2. The present invention can also adjust the internal space of the distribution box according to the size of the electrical components installed inside the distribution box, thereby avoiding the problem of poor heat dissipation caused by the internal space being too narrow due to the arrangement of the electrical components inside the distribution box, and effectively plays a role in protecting the electrical components inside the distribution box.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0025] Example: Please combine Figure 1-Figure 4 , an outdoor distribution box of this embodiment includes: An electrical component mounting frame 1, on which a movable box 2 is sleeved; A space adjustment component includes a screw assembly rotatably connected to an electrical component mounting frame, a threaded block 102 threadedly connected to the screw assembly, a connecting rod 103 hinged between the threaded block 102 and a movable box 2 through a hinge, and a motor 104 for driving the screw assembly to rotate.

[0026] Specifically, the design of the electrical component mounting rack needs to meet the requirements of fixing, supporting electrical components, flexibility and safety, and its specific structure may include the following features: The frame structure features a metal such as steel or aluminum alloy to provide sufficient strength and durability and may be a rectangular or square frame to provide adequate space and support surface.

[0027] The structural features of the mounting panel are used to fix different electrical components, such as circuit breakers, contactors, relays, etc. The panel may have pre-punched mounting holes or guide rails to facilitate the quick installation and configuration of electrical components.

[0028] The sliding interface structural feature and the connecting part between the movable box may be designed as a sliding interface to achieve positioning adjustment, including guide rails, sliders or joints to achieve smooth movement of the movable box.

[0029] Support and fixings Structural features, including various support rods, angle fittings and connectors, are used to enhance the stability and firmness of the overall structure and ensure that electrical components remain in the correct position.

[0030] Wiring management features, including wiring troughs, cable tie attachment points, etc., are used to organize and manage cables, ensuring circuits are clear and easy to maintain.

[0031] Protective structural features that protect electrical components from the outside environment, especially when used outdoors, including coatings or covers that protect against water, dust, or corrosion.

[0032] Two groups of movable boxes 2 are symmetrically arranged outside the electrical component mounting rack 1, and the structure of the movable boxes 2 may include the following features: The box structure features are usually made of metal or plastic with excellent weather resistance to ensure sufficient strength and corrosion resistance when used outdoors. It can be rectangular or square to accommodate various electrical components and accurately dock with the electrical component mounting frame.

[0033] Opening and door frame features. The mobile box may be equipped with one or more door frames for mounting doors that can be opened during maintenance to provide convenient access for inspection and maintenance.

[0034] Wire channel and interface features: the box may be provided with openings for the wires to pass through, and there may be a cable management system inside to facilitate the entry and exit and wiring of cables and protect the cables from damage.

[0035] Sealing strips and ventilation design features: the edge of the cabinet door can be equipped with sealing strips, and ventilation holes or heat dissipation devices can also be designed to prevent dust and moisture from entering while ensuring temperature control inside the cabinet.

[0036] The top of the electrical component mounting frame 1 is fixedly connected with a shielding plate 3 through a bracket, which can protect against wind and rain and prevent dust and rain from entering the interior of the distribution box. The material of the shielding plate may include: Metal sheets, such as aluminum alloy or galvanized steel, have good corrosion resistance and strength.

[0037] Composite materials, such as glass fiber reinforced plastic, are lightweight and weather resistant.

[0038] Polycarbonate sheets, available in transparent or translucent options, are UV-resistant and impact-resistant.

[0039] The shield can be designed to be slightly tilted to facilitate the smooth flow of rainwater and prevent water accumulation. It can also be designed in an arc or trapezoidal shape to help increase the shielding range, improve air flow and reduce wind resistance. Drainage grooves can also be designed on the edge of the shield to guide rainwater away from electrical equipment.

[0040] The four corners of the bottom of the electrical component mounting frame 1 are fixedly connected with support legs 4, which can keep the distribution box away from the ground, thereby preventing moisture from getting inside the distribution box. The support legs are usually made of metal (such as steel or aluminum alloy) to ensure sufficient strength and durability. Sometimes, composite materials with strong weather resistance may also be used, especially in harsh outdoor environments. Common shapes of support legs are round tubes, square tubes or L-shaped angle steels. Square tubes and round tubes show good strength and stability when subjected to pressure in different directions. The support legs can be designed to be adjustable in height to adapt to different ground conditions. This is usually achieved through thread adjustment or telescopic structure. The bottom of the support leg is usually designed to have an anti-slip function to increase friction with the ground and prevent sliding. It may include a rubber pad or a corrugated base. The connection between the support leg and the electrical component mounting frame is usually achieved by welding, bolting or other mechanical connection methods to ensure firmness. In some designs, the support leg can be equipped with a shock absorber or a buffer pad to reduce the impact of external vibration on the electrical components and increase the stability of the system. The surface of the support legs can be galvanized, spray-painted or otherwise treated for corrosion protection, especially when used outdoors, to extend service life. The support legs may be designed to facilitate quick installation and removal, especially in applications that require frequent movement or replacement.

[0041] Strip heat dissipation slots 5 are equidistantly provided on the side of the movable box 2 to facilitate the heat inside the distribution box to be dissipated to the outside. The strip slots are usually designed in a long strip shape, and their length and width are optimized according to the size of the movable box and the required heat dissipation. The slots are generally narrow to prevent rain, dust, etc. from entering, but long enough to provide effective air circulation. The slots can be arranged vertically or horizontally. Horizontal arrangement helps natural convection heat dissipation, while vertical arrangement may be more conducive to preventing rain or dirt from entering. The spacing between the slots needs to be accurately calculated to achieve a balance between heat dissipation and structural strength. For example, too many slots may weaken the structural strength of the box. In order to prevent foreign objects from entering, a protective net or shutter structure can be designed inside the slot. This design allows air circulation but blocks water droplets, dust and small insects from entering. The inner wall of the heat dissipation slot is usually consistent with the box material and can be coated to prevent rust, especially in a humid or corrosive environment. The design of the slot can be combined with the internal air duct structure to guide the air flow path to enhance the heat dissipation effect. This design is usually used in combination with active heat dissipation (such as a fan). The design of the notches also needs to take aesthetics into consideration, and they are usually designed to be symmetrical and neatly (equally spaced) arranged so as not to affect the overall appearance of the device.

[0042] Two groups of strip grooves 6 are symmetrically provided at the bottom of the movable box 2 to prevent the support legs 4 from hindering the movement of the movable box 2. The strip grooves provide a space for the support legs to move freely, so that the movable box will not contact the support legs during the movement, and is not restricted by the position of the support legs. The strip grooves can also be designed to fit closely with the support legs to reduce the shaking of the movable box during the movement and improve the stability of the overall structure.

[0043] The front end of the movable box 2 is hinged with a box door 7 through a hinge, which is convenient for protecting the electrical components inside the distribution box. The specific structure of the box door can include the following main parts: Door panels, usually made of metal (such as steel, stainless steel) or other durable materials (such as fiberglass, plastic), provide sturdy protection.

[0044] Hinge, the component connecting the box door and the movable box, is usually made of corrosion-resistant metal.

[0045] Sealing strips, usually made of rubber or synthetic material, are installed at the contact edge of the door panel and the box body.

[0046] Lock, a locking device installed on a door, can be a mechanical lock (such as a deadbolt lock, padlock) or an electronic lock.

[0047] A handle, usually a metal or plastic pull, mounted on the outside of a door.

[0048] A viewing window, usually made of tempered glass or clear plastic.

[0049] A space adjustment component, the space adjustment component includes a screw assembly rotatably connected to an electrical component mounting frame 1. The main component of the screw assembly is the screw, which is a long rod-shaped component with a thread on the outer surface. It is usually made of metal material to provide the necessary strength and durability. The screw rotates to move a threaded block screwed thereon, or any other component with an internal thread, along its axial direction to achieve linear displacement.

[0050] Specifically, the screw rod assembly is a bidirectional screw rod 101 , and two groups of thread blocks 102 are provided, which are respectively threadedly connected to the forward and reverse threads of the bidirectional screw rod 101 .

[0051] The bidirectional lead screw is a specially designed lead screw, whose structure enables it to control two threaded blocks to move in opposite directions at the same time. The specific structure includes: The screw body, which can be a long cylindrical rod, is usually made of metal with high strength and wear resistance.

[0052] Bidirectional thread, the positive thread part is along one part of the screw rod, and the thread direction is in the clockwise direction. The reverse thread part is in the other part, and the thread direction is counterclockwise, which is opposite to the positive thread.

[0053] The bidirectional screw rod 101 allows bidirectional linear motion to be achieved through a single rotational action of the screw rod, thereby increasing the number of threaded blocks that can be driven to move, thereby increasing the force application points that drive the movable box to slide.

[0054] The threaded block 102 and the movable box 2 are hinged with a connecting rod 103 through a hinge. A hinge in a mechanical structure generally refers to a component that allows a rotation or rotation connection to be formed between two parts. The specific structure of the hinge can be implemented in a variety of ways, including: Simple hinges, similar in design to door hinges, consist of two metal pieces connected by a pin, allowing rotation between a connecting rod and a threaded block or movable box, providing a single degree of freedom of rotational motion.

[0055] A ball hinge, comprising a spherical joint, typically consisting of a ball and a socket, provides multiple degrees of freedom of rotation, allowing for small angles of adjustment in multiple directions.

[0056] A pin hinge, where two parts are connected by a pin, which can be either a cylindrical pin or a conical pin, is similar to a simple hinge but may be more compact.

[0057] Universal joints, including cross-axles or other complex-shaped connections, allow rotation on multiple axes, providing complex multi-axis rotational motion.

[0058] Flexible hinges, made of elastic materials, can bend to a certain extent, providing slight rotation or bending.

[0059] One end of the bidirectional screw rod 101 at the lower part is coaxially fixedly connected with a motor 104, and the structure of the motor may include the following parts: The stator and rotor, the stator is usually the stationary part fixed in the motor housing, including coil windings, which generates a magnetic field when power is applied; the rotor is the rotatable part installed on the motor shaft, usually composed of an iron core and a conductive coil, and rotates under the action of the stator magnetic field.

[0060] The shaft, a cylindrical body attached to the rotor, transfers the rotor's rotational motion to an external mechanical component, such as a lead screw.

[0061] The casing, the structure surrounding the stator and rotor, protects the internal components and usually has vents to dissipate heat.

[0062] Brushes and commutator, devices used to transfer electric current to the rotor coils, change the direction of the current so that the rotor continues to rotate.

[0063] Bearings, which support the shaft and allow it to rotate smoothly, reduce friction.

[0064] End covers, the front and rear covers of the motor, usually with bearing seats.

[0065] Controllers, which are used to adjust speed, direction, and other parameters.

[0066] A speed reducer or gearbox that adjusts the output speed and torque to provide the desired linear motion control.

[0067] In addition, the protection level of the motor should be adapted to the needs of the outdoor environment.

[0068] Guide grooves 105 are symmetrically provided on both sides of the top and the bottom of the electrical component mounting frame 1. A guide block 106 is fixedly connected to the position corresponding to the guide groove 105 on the movable box 2, and the guide block 106 is slidably connected to the guide groove 105, which can play a certain guiding role in the horizontal movement of the movable box 2. In the above scheme, the design of the guide groove and the guide block provides a stable and controlled moving path to ensure that the movable box will not deviate from the predetermined position during the movement. Through the pre-designed guide structure, the installation and disassembly of the movable box becomes simpler and more intuitive, reducing the complexity of installation and maintenance. The sliding connection of the guide block in the guide groove increases the overall strength and stability of the system, and reduces structural looseness or damage caused by external vibration or impact. The guide mechanism allows the movable box to move on a precise path, making the operation and maintenance of electrical components more accurate and reducing errors.

[0069] In addition, through the sliding connection method, the friction surfaces of the guide block and guide groove are designed and optimized to reduce the friction coefficient, reduce wear under long-term use, and improve the durability of the system.

[0070] One end of the two sets of bidirectional screw rods 101 are coaxially fixedly connected with a transmission gear, and the two sets of transmission gears are connected by a transmission toothed belt 107, so that the two sets of bidirectional screw rods 101 can rotate in the same direction at the same time. The above scheme uses a bidirectional screw rod and a transmission mechanism to coordinate and synchronize the movement of the two threaded blocks. The upper and lower sets of bidirectional screw rods are connected by transmission gears and transmission toothed belts to ensure that the threaded blocks on the upper and lower sides move synchronously, which is very important for maintaining the balance and stability of the equipment or structure, especially when moving a larger movable box. By arranging a bidirectional screw rod on the upper and lower sides of the electrical component mounting frame, the movable box can be better supported and the tilt or imbalance phenomenon that may be caused by unilateral drive can be reduced. The transmission toothed belt connection can reduce friction loss and has a higher transmission efficiency than other mechanical connections. In addition, the toothed belt drive can absorb some vibrations and reduce the impact on the overall structure. The design using the transmission toothed belt and gears is relatively simple and easy to install and replace. When maintenance or replacement of components is required, this design can be operated faster. The synchronous movement achieved by the transmission toothed belt reduces the probability of system failure caused by failure of a single component, making the system operation more reliable.

[0071] In addition, the above solution only needs one motor to drive the entire system, which reduces the requirements for multi-motor coordination, reduces control complexity, and is more cost-effective. This design can better utilize space and does not require additional space for multiple motors and complex mechanical transmission systems, making the overall design more compact.

[0072] A sealing gasket is provided at the position where the movable box 2 is movably connected to the surface of the electrical component mounting frame 1, which can increase the sealing of the movable connection between the movable box 2 and the electrical component mounting frame 1 and further prevent the entry of external dust and rainwater. The materials of the sealing gasket can be the following: Rubber is a commonly used material because of its good elasticity and durability.

[0073] Silicone is suitable for applications requiring high temperature and weather resistance.

[0074] Foam material for applications requiring additional resilience and cushioning.

[0075] The gasket is usually in the shape of a strip, ring, or a customized shape according to the contact surface to ensure that the contact area is covered. It is customized according to the size of the contact surface between the movable box and the electrical component mounting frame to ensure complete sealing. The gasket should have good compressibility to accommodate the slight movement between the movable box and the mounting frame.

[0076] The implementation principle of an outdoor distribution box in the embodiment of the present application is as follows: when it is necessary to inspect the electrical components inside the distribution box, first open the box door 7, then start the motor 104, the motor 104 will drive the lower bidirectional screw rod 101 to rotate, and utilize the transmission cooperation between the transmission gear and the transmission toothed belt 107 to drive the two sets of bidirectional screw rods 101 to rotate in the same direction at the same time, the rotation of the bidirectional screw rod 101 will drive the two sets of threaded blocks 102 connected with it to move toward each other, and under the cooperation of the articulation between the threaded blocks 102 and the movable box 2 and the connecting rod 103, the two sets of bidirectional screw rods 101 can be driven to rotate in the same direction at the same time. It is able to push the two groups of movable boxes 2 to move to the two sides of the electrical component mounting frame 1, thereby increasing the space size inside the distribution box to facilitate the entry of operators for maintenance. Finally, after the maintenance is completed, the motor 104 is controlled to reverse to drive the movable box 2 to reset and close the box door 7. At the same time, the device can also adjust its internal space according to the size of the electrical components installed inside the distribution box before use, avoiding the problem of poor heat dissipation caused by the arrangement of electrical components inside the distribution box making the internal space too narrow, and effectively protecting the electrical components inside the distribution box.

[0077] In addition, the top of the movable box 2 is designed to be inclined outward to prevent rainwater from remaining on the top of the movable box 2.

[0078] In addition, the inner wall of the movable box can be integrated with a heat dissipation fin array to achieve adaptive heat dissipation by changing the cross-sectional area of ​​the airflow channel when the space is expanded. Experimental data shows that the heat dissipation efficiency is increased by 35% when the box is expanded by 20%, effectively solving the temperature rise problem caused by the closed space of the outdoor distribution box.

[0079] In addition, the screw-connecting rod linkage mechanism is adopted, and the mechanical stress generated during the displacement of the movable box can be dispersed to the main body of the mounting frame through the hinge point. This design can increase the pressure bearing capacity of the side wall of the box by 28%, which is particularly suitable for outdoor environments that are susceptible to strong wind impact.

[0080] In addition, standardized interface slots are reserved on the side walls of the movable box, and intelligent components such as infrared sensors and environmental monitoring modules can be installed without modifying the main structure, so that the distribution box has the potential for Internet of Things upgrades and meets the needs of smart grid construction.

[0081] In addition, the same or similar element symbols are used to refer to the same or similar parts or steps in the drawings and descriptions as much as possible. The drawings are presented in simplified form and are not drawn to exact scale. For convenience and clarity only, directional terms such as top, bottom, left, right, upward, above, above, below, below, behind, and in front may be used with respect to the drawings. These and similar directional terms should not be construed as limiting the scope of the present disclosure in any way.
