Description

Technical Field

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

[0002] The distribution box is an important component in the power system, mainly used for the distribution, control and protection of electricity. The distribution box can be used to manage the power distribution in the building, manage the power supply of complex power systems and machinery and equipment, or manage power in municipal engineering, transportation systems, etc. The power equipment in the distribution box may generate noise during operation, and high-voltage electrical appliances are dangerous, so the distribution box is often placed outdoors to reduce the noise impact on the indoor environment. However, in this case, changes in the outdoor environment, such as rain, will affect the power equipment inside the distribution box.

[0003] To solve the above problems, a rainproof distribution box is disclosed in the patent with announcement number CN221652063U. The device can shield the heat dissipation louvers of the distribution box body from rain by setting a rain shield component to prevent rainwater from entering the interior of the distribution box body through the heat dissipation louvers.

[0004] However, when the device is actually used, although it can prevent rainwater from entering the interior of the distribution box through the heat dissipation louvers, there is often water accumulation on the wires connected to the distribution box. The accumulated water will slowly flow into the distribution box along the reserved gaps in the distribution box due to gravity, and the wires are directly connected to the electrical connections of the power equipment inside the distribution box. In this way, even if a small amount of rainwater enters the distribution box along the wires, it may cause accidents such as short circuits and fires.

[0005] In summary, there is a need for a distribution box that can remove rainwater from the distribution lines directly connected thereto. Summary of the invention

[0006] The invention aims to provide an outdoor rainproof distribution box.

[0007] The technical solution adopted by the present invention to solve the above problems is: an outdoor rainproof distribution box, comprising: A distribution box, wherein electrical components are arranged inside the distribution box, distribution wires are connected to the electrical components, and a wire threading hole is arranged on the side of the distribution box, and the distribution wires pass through the wire threading hole; The dewatering assembly comprises a water retaining ring movably sleeved on the outside of the distribution line, and a transmission assembly driving the water retaining ring to move back and forth on the distribution line.

[0008] The water retaining ring is driven by the transmission component to move along the surface of the wire and actively scrape off the rainwater accumulated on the surface of the wire. This dynamic removal mechanism can effectively remove the moisture attached to the wire and prevent the rainwater from flowing into the distribution box along the wire due to gravity. Compared with traditional static seals (such as rubber rings and fixed baffles), the dynamic scraping design of the water retaining ring can cope with continuous rainfall or high humidity environments, reduce long-term hidden dangers caused by residual or infiltrated rainwater, and reduce maintenance requirements.

[0009] In addition, the water retaining ring can also serve as a physical barrier when stationary, directly cutting off the flow path of rainwater flowing along the surface of the wires into the inside of the distribution box, preventing it from penetrating into the inside through the reserved pores of the distribution box. By preventing moisture from entering the distribution box, the water retaining ring fundamentally avoids short circuits, arc discharges or electrical fires caused by moisture in the electrical equipment inside the box (such as terminal blocks, switch contacts, etc.), significantly improving safety.

[0010] A further preferred technical solution is that the transmission assembly includes a connecting rod fixedly connected to the water retaining ring, a fixing rod fixedly connected to the side of the connecting rod, a motor fixedly connected to the distribution box, a screw rod coaxially fixedly connected to the rotor end of the motor, and a screw tube connected to the external thread of the screw rod; the screw tube is fixedly connected to the fixing rod.

[0011] A further preferred technical solution is that a box door is hinged at the front end of the distribution box.

[0012] A further preferred technical solution is that a plurality of heat dissipation openings are provided at the lower portion of the cabinet door.

[0013] A further preferred technical solution is that a sealing ring is provided inside the threading hole.

[0014] A further preferred technical solution is that a guide rod is fixedly connected to one side of the distribution box body and the guide rod is slidably connected to the connecting rod.

[0015] A further preferred technical solution is that the end of the guide rod is fixedly connected to a limiting plate.

[0016] A further preferred technical solution is that a rain shield is fixedly connected to the top of the distribution box body, and the top of the rain shield is a slope inclined to the side.

[0017] A further preferred technical solution is that: the external fixing sleeve of the distribution line is provided with a support frame and the support frame is fixedly connected to the distribution box.

[0018] A further preferred technical solution is that a supporting base is fixedly connected to the bottom of the distribution box.

[0019] In summary, the present invention has the following benefits: 1. The transmission assembly of the present invention drives the lead screw to rotate through a motor, and utilizes the threaded connection between the lead screw and the screw tube, and the sliding cooperation between the guide rod and the connecting rod, so that the screw tube can be driven to move horizontally, thereby driving the water retaining ring to move together to clean the rainwater on the surface of the distribution line exposed to the outside of the distribution box, so as to prevent the residual water on the wire from entering the interior of the distribution box.

[0020] 2. The present invention can block rainwater flowing along the distribution line by means of the water retaining ring to prevent it from entering the threading hole. By adding a sealing ring in the threading hole, the waterproof ability of the threading point of the distribution box can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The specific structure of the distribution box 1 may include: The housing can be made of metal or high-strength plastic to have good mechanical strength and corrosion resistance. The housing itself has a certain protection level, such as IP65, IP66, to ensure waterproof, dustproof, and corrosion-resistant, and is suitable for outdoor use.

[0031] Internal brackets and mounting plates are used to fix and support internal electrical components to ensure stability. They can be metal plates used to mount electrical components such as circuit breakers, contactors, relays, etc., which can be disassembled to facilitate assembly and maintenance.

[0032] Two sets of distribution wires 2 are fixedly connected to the electrical components. The specific structure of the distribution line may include: Conductors, which can be made of copper or aluminum, have good conductivity and act as carriers of electric current, transferring power from the source to the load.

[0033] The insulation layer, which can be made of polyvinyl chloride, polyethylene or cross-linked polyethylene, prevents current leakage, protects the conductor from the external environment, and ensures safety.

[0034] Shielding, which can be made of metal foil or braided wire, is used to reduce EMI and RFI and protect signal integrity, especially in environments where protection from interference is required.

[0035] The filling layer can be made of some fiber materials. In multi-core cables, the filling layer is used to maintain the circular structure of the cable and prevent the conductors from moving relative to each other.

[0036] The jacket, which is usually the same material as the insulation and can be PVC or PE, but is thicker and more durable, and is used to provide additional mechanical protection against physical damage, moisture and other environmental factors.

[0037] Armor layers, which can be made of steel wire or steel tape, are used in environments where additional protection is required to enhance the mechanical strength and compression resistance of the cable.

[0038] The design of the threading hole should have certain waterproof performance, which can include the following forms: Threaded adapter, the threading hole can be designed as an internal thread structure to facilitate the installation of cable glands of different specifications. This design allows for quick replacement and tightening, enhancing the sealing effect.

[0039] Conical design, the inside of the wire hole can be tapered to better guide the distribution wires and improve waterproof performance.

[0040] Cable locking head: The outside of the threading hole can be equipped with a cable locking head, which can tighten the cable by rotating to further improve the sealing and fixing effect. The locking head is usually made of materials with good weather resistance, such as corrosion-resistant metal or engineering plastic.

[0041] Double or multi-layer sealing: The threading hole can be designed with a double or multi-layer sealing structure to provide additional protection. This design is usually used in extreme environmental conditions to ensure higher sealing reliability.

[0044] Two sets of threading holes 3 are symmetrically opened on one side of the distribution box 1, and the distribution wires 2 pass through the threading holes 3. A rain cover 4 is fixedly connected to the top of the distribution box 1. The rain cover on the distribution box is mainly used to prevent rainwater from directly entering the box, thereby protecting the internal electrical components. The forms that can be realized include: The double slope design is similar to the double slope structure of the roof, and rainwater is discharged from both sides. This design provides better drainage capacity and is suitable for areas with heavy rainfall.

[0045] The single slope design has a simple single-sided inclined surface on the top, which can effectively direct rainwater to one side. This design is simple and easy to manufacture and install.

[0046] The curved cover has a curved top. This design is not only beautiful, but also effectively reduces the retention and accumulation of rainwater.

[0047] The multi-layer stepped type is designed in a multi-layered step shape, with each step extending outward to guide rainwater dripping layer by layer. It is suitable for applications that require additional protection.

[0048] Equipped with rain gutters, the edges are designed with rain gutters to collect and guide rainwater to prevent it from dripping directly around the distribution box.

[0049] Removable rain cover, this cover can be fixed by screws or buckles, and is easy to remove for maintenance and cleaning.

[0050] Integrated ventilation design, with ventilation holes or grilles integrated on the inside of the rain cover, can both keep out the rain and provide ventilation and heat dissipation functions.

[0051] Windproof reinforcement design: In areas susceptible to strong winds, the design can be reinforced by increasing the thickness, adding additional support or weighting to prevent it from being blown away by strong winds.

[0052] The front end of the distribution box 1 is symmetrically hinged with two sets of box doors 5, which can protect the electrical components inside. The box door is an important component of the distribution box and may include the following structures and features: Material characteristics: the box door can be made of the same or similar materials as the distribution box body, such as steel plate, aluminum alloy or waterproof plastic to ensure overall strength and weather resistance.

[0053] Connection feature: the door is hinged to the distribution box body through a hinge and can be set on one side so that the door can be opened and closed smoothly. The hinge needs to be corrosion-resistant and able to withstand frequent opening and closing operations.

[0054] Sealing feature: the inner edge of the box door can be equipped with a sealing strip to prevent dust and moisture from entering the interior of the box. The sealing strip material can be rubber or other elastic waterproof materials.

[0055] Observation window: The box door can be designed with a transparent observation window so that the internal instruments or status indicators can be viewed without opening the door. The observation window material is usually tempered glass or impact-resistant plastic.

[0056] Ground connection: the box door can be grounded to the box body through a grounding wire to prevent static electricity accumulation.

[0057] The lower part of the box door 5 is provided with heat dissipation openings 6 at equal intervals, so as to dissipate the heat generated by the electrical components when they are working to the outside, thereby playing a role in cooling. The heat dissipation openings are intended to facilitate air circulation and heat dissipation inside the box, and the implementation forms may include: Parallel slit type, with multiple parallel slits opened at the bottom of the door. This design is simple, effective and easy to manufacture.

[0058] Honeycomb mesh type, by punching or stamping on the metal plate to form a honeycomb grid hole, this design can increase the surface area while maintaining structural strength.

[0059] Louvered, similar to a Venetian blind design, the openings are angled to keep rain and debris out while allowing air to circulate.

[0060] Trapezoidal hole type, with multiple trapezoidal holes, this design not only increases the aesthetics, but also effectively guides the airflow.

[0061] Circular hole array: multiple circular holes are arranged in a regular array and evenly distributed at the bottom of the door to facilitate air exchange.

[0062] The long hole type is designed as a horizontal or vertical long hole. The length and interval of the holes can be adjusted as needed to achieve the best heat dissipation effect.

[0063] The corrugated hole type uses a special mold to punch corrugated holes on the door to increase the air contact area and convection effect.

[0064] The external fixed sleeve of the distribution line 2 is provided with a support frame 7 and the support frame 7 is fixedly connected to the distribution box 1, which can support the distribution line 2. The support frame 7 can also play the role of clamping and fixing the distribution line 2, so that the relative position of the distribution line 2 and the distribution box 1 is fixed. The implementation form may include: The L-shaped support frame is connected to the distribution box on one side and supports the cables on the other side. It is suitable for vertical or horizontal wiring.

[0065] The U-shaped support frame adopts a U-shaped design. The cables can be placed in the U-shaped groove. There are usually fixing clips or cable ties to fix the cables. It is simple and universal.

[0066] The cantilever support frame leads the cables out of the distribution box through the cantilever structure, which is suitable for occasions that require support at a certain distance.

[0067] The ring support frame has a ring or semi-circular structure, which is used to wrap and support cables and is suitable for parallel fixing of multiple cables.

[0068] The slide rail support frame is equipped with a slide rail, which can slide and adjust the position of the cables during installation, making wiring and maintenance easier.

[0069] Perforated plate supports use metal or plastic plates with multiple holes. Cables can be fixed to the plate with cable ties, which is highly flexible.

[0070] The frame-type support frame has a more complex structure and provides all-round support and protection. It is suitable for large and important cable systems.

[0071] The embedded support frame is directly embedded into the design of the distribution box, hiding part of the structure to save space.

[0072] The water removal assembly includes a water retaining ring 101 movably mounted on the outside of the distribution line 2. The inner diameter of the water retaining ring 101 matches the diameter of the distribution line 2. The specific structural design of the water retaining ring is crucial to effectively prevent water from entering the distribution box along the distribution line. The key points may include: Material selection: Water retaining rings are usually made of waterproof and corrosion-resistant elastic materials such as rubber, silicone or plastic. These materials can effectively resist the influence of environmental factors and maintain close contact with the distribution line.

[0073] Shape selection, the water retaining ring is usually a circular ring design, close to the outer diameter of the distribution line, and the inner diameter is slightly larger than the outer diameter of the distribution line to ensure that it can fit tightly on the wire.

[0074] The inner ring sliding characteristics, the inner surface may be designed with a smooth surface, or smooth components, to improve the sliding performance on the insulation layer of the distribution line.

[0075] Installation and fixing characteristics, the water retaining ring design allows for quick installation and removal, facilitating regular maintenance and inspection.

[0076] The transmission assembly is used to drive the water retaining ring to move back and forth on the distribution line to ensure its water removal function. The forms that can be realized include: Electric motor driven, a small electric motor is connected to the water retaining ring, and drives the reciprocating motion of the water retaining ring through a specific transmission mechanism.

[0077] Mechanical spring device, using the elastic force of the spring, so that the water retaining ring on the distribution line naturally rebounds back and forth. The movement is achieved by periodically stretching and releasing the spring manually or by other mechanical means.

[0078] The gear and rack mechanism uses a combination of gears and racks to rotate the gears manually or electrically, and drives the water retaining ring to move on the distribution line through the rack.

[0079] The eccentric wheel mechanism generates reciprocating motion through the rotation of the eccentric wheel, connects the water retaining ring and drives it to move.

[0080] The cam mechanism uses a specially shaped cam to rotate and push the slider or connecting rod to make the water retaining ring reciprocate.

[0081] Hydraulic or pneumatic drive, using hydraulic cylinder or air cylinder to produce linear reciprocating motion, and the water retaining ring is driven to move by the push and pull action of the piston.

[0082] Magnetic drive uses an internally mounted magnet to influence its position through an external movable magnet or a variable electromagnetic field, driving the water retaining ring to move.

[0083] In this embodiment, the transmission assembly includes two groups of water retaining rings 101, between which a connecting rod 102 is fixedly connected, one side of the connecting rod 102 is fixedly connected to a fixing rod 103, the back of the distribution box 1 is fixedly connected to a motor 104, the rotor end of the motor 104 is coaxially fixedly connected to a screw rod 105, the external thread of the screw rod 105 is connected to a screw tube 106 and the screw tube 106 is fixedly connected to the fixing rod 103, and a sealing ring 107 is provided inside the threading hole 3 to improve the waterproof ability of the threading point of the distribution box 1, two groups of guide rods 108 are symmetrically fixedly connected to one side of the distribution box 1 and the two groups of guide rods 108 are slidably connected to the connecting rod 102 at the same time, which can play a certain guiding role in the horizontal movement of the water retaining ring 101, and the end of the guide rod 108 is fixedly connected to a limiting plate 109 to prevent the connection rod 102 from detaching from the guide rod 108.

[0084] The above transmission assembly is a kind of motor drive implementation. It can be divided into a driving part and a pushing part. The driving part includes: The motor, as the main driving component, provides rotational power. It converts electrical energy into mechanical energy to drive the screw to rotate.

[0085] The screw rod is coaxially connected to the motor and receives the rotational power of the motor. The rotation of the screw rod is the core driving force of the entire system movement.

[0086] The promotion department includes: The solenoid is connected to the external thread of the lead screw, and the rotation of the lead screw will cause the solenoid to move along the lead screw. Since the solenoid is fixedly connected to the fixed rod, the rotational motion of the lead screw is converted into linear motion.

[0087] The fixed rod is connected to the screw tube and fixed to the side of the connecting rod, and plays the role of transmitting the linear movement of the screw tube to the connecting rod.

[0088] The connecting rod is fixedly connected to the water retaining ring and is driven by the fixing rod to move along the distribution line, thereby driving the water retaining ring to move back and forth.

[0089] In addition, the sealing ring 107 is used to ensure the sealing of the device when the cable passes through, to prevent water, dust or other pollutants from entering, and the implementation form may include: The rubber ring is a flexible rubber ring that can fit the cable tightly and provide good sealing. The ring is usually set around the threading hole or in the internal groove.

[0090] The conical sealing ring adopts a conical design, so that when the cable passes through, the sealing ring can be gradually compressed, increasing the contact area and improving the sealing effect.

[0091] Split seals are designed as two halves or multiple pieces, which can be installed and replaced without removing the installed cables. This form is convenient for maintenance.

[0092] Bellows seals, with a bellows structure, can adapt to cables of different diameters while providing additional flexibility to cope with vibration and movement.

[0093] Adjustable seals, this design includes an adjustable clamping mechanism that allows the seal to be adjusted to the size of the cable to ensure a snug fit.

[0094] Multi-hole gaskets use gaskets with multiple pre-made holes, which are suitable for multiple cables to pass through at the same time. They can be cut or punched to accommodate different cable diameters.

[0095] The self-adhesive sealing ring is equipped with a self-adhesive layer, which can automatically adhere to the wall of the threading hole during installation, simplifying the installation steps and enhancing the sealing effect.

[0096] In addition, the guide rod 108 is a part of the driving portion of the transmission assembly, and is intended to enable the connecting rod to move along the distribution line.

[0097] In addition, the limiting plate 109 is also a part of the driving portion of the transmission assembly, and is intended to enable the connecting rod to move within a limited area.

[0098] The implementation principle of an outdoor rainproof distribution box in the embodiment of the present application is as follows: the rainwater splashed onto the distribution line 2 and flowing along the distribution line 2 can be blocked by the provided water retaining ring 101 to prevent it from entering the threading hole 3. A sealing ring 107 is added to the threading hole 3 to further improve the waterproof ability of the threading point of the distribution box body 1. The motor 104 is started, and the motor 104 drives the screw rod 105 to rotate alternately forward and reverse. The threaded connection between the screw rod 105 and the screw tube 106 and the sliding cooperation between the guide rod 108 and the connecting rod 102 can drive the screw tube 106 to move horizontally, thereby driving the two groups of water retaining rings 101 to move together to scrape the rainwater on the surface of the distribution line 2 exposed to the outside of the distribution box body 1, and the support frame 7 clamps and fixes the distribution line 2, so that the distribution line 2 will not change position due to the movement of the water retaining ring 101. The scraping of the water retaining ring 101 can accelerate the drying speed of the surface of the distribution line 2.

[0099] In addition, a further improvement is that a support base 8 is fixedly connected to the bottom of the distribution box 1, which can lift the distribution box 1 off the ground to prevent the inside of the distribution box 1 from getting damp due to water accumulation on the ground. The forms that can be realized include: Fixed base, the distribution box is directly fixed on the concrete or steel base, connected by bolts or welding, suitable for permanent installation.

[0100] Adjustable base with adjustable height design to facilitate installation on uneven or sloping ground, ensuring the level and stability of the distribution box.

[0101] The frame structure base uses a metal frame structure to provide comprehensive support for the distribution box, while making it easy to wire or install other facilities inside the base.

[0102] Platform base, a horizontal platform, usually made of steel or concrete, suitable for applications requiring moisture protection or increased height.

[0103] Mobile base, equipped with rollers or pulleys, is convenient for moving the switch box when needed, suitable for temporary installation or environment requiring flexible layout.

[0104] Embedded base, part of the structure is embedded in the ground, providing better stability and anti-overturning ability, suitable for outdoor environments with strong winds.

[0105] The anchored base is fixed to the ground by anchor bolts to increase wind resistance and stability. It is usually used outdoors or in exposed conditions.

[0106] The suspended base is suitable for special environments, such as distribution boxes that need to be installed at high places, and is fixed to the building structure through a hanging device.
