Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a composite multifunctional outdoor electric meter box. Background Art

[0002] Electricity meter boxes are primarily installed outdoors, including cable branch boxes, low-voltage distribution boxes, and electrical equipment such as streetlight and traffic light control boxes used in public power grids. Due to their high and relatively hidden location, if electrical components malfunction within meter boxes, sparks could ignite fires. This could not only damage electrical equipment and disrupt power supply, but also be difficult to detect in the early stages and prevent timely rescue efforts. This fire could easily spread and cause a larger fire, impacting personal safety and power supply. Furthermore, meter boxes attract birds to nest nearby. Birds' pecking can damage the box door, opening it and further attracting birds to nest inside. Nesting materials used by birds, such as fluff, paper scraps, wire, metal wire, and damp branches, can damage electronic components within the meter box, ignite flammable materials, and potentially cause short circuits.

In this embodiment, the electric energy meter box integrates a plurality of electric energy meters 4, thereby realizing the monitoring and control of a plurality of branches.

[0024] In this embodiment, if Figure 1 and Figure 2 As shown, a plurality of bird-repelling components 3 are provided on the box body 1 .

[0025] The composite multifunctional outdoor electric meter box of this embodiment includes a box body 1, a fire extinguishing component 2 and a bird-repelling component 3. An electric energy meter 4, a controller 5 and a main switch 6 are provided in the box body 1. The fire extinguishing component 2 is arranged in the box body 1, and includes a fixing frame 21, a fire extinguisher body 22 and a temperature sensor. The fire extinguisher body 22 is detachably installed in the fixing frame 21, which can effectively fix the fire extinguisher body 22 and facilitate the replacement of the fire extinguisher body 22; the temperature sensor is used to monitor the temperature in the box body 1. When the temperature in the box body 1 reaches a preset value, the fire extinguisher body 22 is activated to spray flame retardant and fire-extinguishing substances to extinguish the fire, prevent the fire from spreading, and reduce fire hazards. The bird-repelling component 3 is arranged on the box body 1, which can prevent birds from nesting near the electric meter box, prevent birds from damaging the electric meter box, and prevent safety hazards caused by bird nesting. The composite multifunctional outdoor electric meter box of this embodiment has protective, fireproof and bird-proof functions, and has good reliability and practicality.

[0026] Figure 5 This is a structural diagram of a fire extinguisher body 22 provided in this embodiment. Figure 6 This is a structural diagram of a fixing frame 21 provided in this embodiment. Figure 3 、 Figure 5 and Figure 6 As shown, the fixing frame 21 is provided with a slot 24. The slot 24 is provided with a limiting assembly 25. The fire extinguisher body 22 is provided with a block 26. When the fire extinguisher body 22 is installed in the fixing frame 21, the limiting assembly 25 limits the block 26 in the slot 24.

[0027] In this embodiment, if Figure 6 As shown, the fixing frame 21 is provided with a through hole 27 for the sensor line 23 to pass through. When the temperature inside the box 1 reaches a preset value and a fire occurs, the fire extinguisher body 22 receives a fire signal from the temperature sensor through the sensor line 23, triggering the fire extinguisher body 22 to automatically start and perform a fire extinguishing operation.

[0028] The fire extinguisher body 22 in this embodiment is a device installed in the electric meter box that automatically activates and extinguishes the fire when a fire is detected. Examples include a flexible temperature-sensing self-activating fire extinguishing device, a non-pressure-storage perfluorohexanone automatic fire extinguishing device, an aerosol automatic fire extinguishing device, a carbon dioxide automatic fire extinguishing device, and a dry powder automatic fire extinguishing device.

[0029] In this embodiment, a fixing frame 21 is provided in the box body 1 for mounting the fire extinguisher body 22, and a limiting assembly 25 is used to restrict the block 26 on the fire extinguisher body 22 in the card slot 24, which can prevent the fire extinguisher body 22 from sliding out of the fixing frame 21, and avoid the fire extinguisher body 22 from shaking or shifting in the box body 1, thereby ensuring that the fire extinguisher body 22 can work normally when fire extinguishing is required.

[0030] Figure 7 This is a schematic diagram of the structure of a limit assembly 25 provided in this embodiment. Figure 7 As shown, the limiting assembly 25 includes a shell 251, a limiting block 253 and a connecting rod 255. The shell 251 is arranged on the fixed frame 21. A slide groove 252 is provided in the shell 251. One end of the slide groove 252 has an opening, and the other end of the slide groove 252 is a closed end. The opening faces the card slot 24. The limiting block 253 is slidably arranged in the slide groove 252. The connecting rod 255 extends into the slide groove 252 from the closed end and is connected to the limiting block 253. A spring 256 is sleeved on the connecting rod 255. The spring 256 is located in the slide groove 252. The spring 256 is connected between the limiting block 253 and the closed end. The limiting block 253 can extend out of the opening under the support of the spring 256 to limit the card block 26 in the card slot 24. Pulling the connecting rod 255 outward from the closed end can compress the spring 256 and retract the limiting block 253 into the sliding groove 252 to release the restriction of the limiting block 253 on the locking block 26 .

[0031] In this embodiment, Figure 7As shown, two connecting rods 255 are connected to the limit block 253. By using the two connecting rods 255 to push the limit block 253 to move, the limit block 253 can be evenly stressed and move more smoothly.

[0032] When installing the fire extinguisher body 22, the block 26 on the fire extinguisher body 22 is aligned with the slot 24 on the fixing frame 21, and the fire extinguisher body 22 is then installed into the fixing frame 21. As the block 26 slides into the slot 24, the connecting rod 255 is pulled outward from the closed end, compressing the spring 256 and retracting the stopper 253 into the chute 252, allowing the block 26 to slide into the base of the slot 24. The connecting rod 255 is then released, and the stopper 253, supported by the spring 256, extends out of the chute 252, thereby confining the block 26 in the slot 24. The stopper assembly 25 of this embodiment facilitates installation and removal of the fire extinguisher body 22.

[0033] Among them, such as Figure 7 As shown, a top sheet 257 is provided at one end of the connecting rod 255 located outside the closed end.

[0034] In this embodiment, Figure 7 As shown, the connecting rod 255 and the top plate 257 are an integrally formed structure.

[0035] In this embodiment, a top plate 257 is provided at the free end of the connecting rod 255 , which can prevent the limiting block 253 from sliding out of the open end of the sliding groove 252 and facilitate pulling the connecting rod 255 .

[0036] Among them, such as Figure 7 As shown, the end surface of the stopper 253 facing the slot 24 is an inclined surface 254. When the fire extinguisher body 22 is installed in the fixing frame 21, as the block 26 slides into the slot 24, the block 26 can press against the inclined surface 254 of the stopper 253, causing the block 253 to overcome the elastic force of the spring 256 and slide into the slot 252. When the block 26 slides to the base of the slot 24, the block 26 and the inclined surface 254 are offset, and the spring 256 releases its elastic potential energy, pushing the stopper 253 out of the slot 252, thereby retaining the block 26 and preventing it from sliding out of the slot 24. When the fire extinguisher body 22 needs to be disassembled, the connecting rod 255 is pulled outward from the closed end, which compresses the spring 256 and retracts the stopper 253 into the slot 252, releasing the restraint imposed by the block 253 on the block 26.

[0037] Figure 8 This is a schematic diagram of the installation state of a bird-repelling assembly 3 provided in this embodiment. Figure 4 and Figure 8As shown, the connection structure 33 includes: a mounting groove 331, an elastic connecting plate 332 and a fixing ring 333. The mounting grooves 331 are symmetrically arranged on both sides of the mounting rod 31 and extend along the axial direction of the mounting rod 31. Each elastic connecting plate 332 is arranged in a mounting groove 331. The fixing ring 333 is sleeved on the mounting rod 31 and is connected to the mounting rod 31 by threaded engagement. The fixing ring 333 restricts the elastic connecting plate 332 in the mounting groove 331. After removing the fixing ring 333, one end of the elastic connecting plate 332 can extend out of the mounting groove 331 under the action of its own elastic force and extend along the radial direction of the mounting rod 31 to be clamped on the box body 1.

[0038] In this embodiment, if Figure 8 As shown, the mounting rod 31 is provided with an external thread 34, and the fixing ring 333 is connected to the mounting rod 31 through threaded engagement. Such an arrangement can ensure the stability of the fixing ring 333 and facilitate the installation and disassembly of the fixing ring 333.

[0039] When installing the bird-repellent assembly 3 of this embodiment, first extend the end of the mounting rod 31 provided with the connecting structure 33 into the housing 1. Then remove the fixing ring 333, allowing the pair of elastic connecting plates 332 to extend out of the mounting groove 331 under their own elastic force and snap into the housing 1. Then, install the fixing ring 333 on the mounting rod 31 to abut against the elastic connecting plates 332, preventing the elastic connecting plates 332 from retracting into the mounting groove 331 due to gravity, causing the bird-repellent assembly 3 to fall off. When disassembling the bird-repellent assembly 3 of this embodiment, first remove the fixing ring 333, then manually press the elastic connecting plates 332 into the mounting groove 331, and then install the fixing ring 333 on the mounting rod 31 to confine the elastic connecting plates 332 in the mounting groove 331. The bird-repellent assembly 3 can then be removed.

[0040] Among them, such as Figure 4 and Figure 8 As shown, a mounting hole is provided in the housing 1. The diameter of the mounting hole is larger than the outer diameter of the fixing ring 333. The mounting rod 31 is extended through the mounting hole into the interior of the housing 1 until the fixing ring 333 enters the housing 1. The fixing ring 333 is removed, and one end of the elastic connecting plate 332 extends out of the mounting groove 331 and snaps onto the inner wall of the housing 1 to connect the mounting rod 31 to the housing 1. This embodiment provides a mounting hole in the housing 1 for installing the bird repellent assembly 3, thereby optimizing the structure of the electric meter box.

[0041] In this embodiment, a bird-repellent assembly 3 is installed in the mounting hole on the box body 1, which can prevent birds from perching around the meter box or entering the inside of the meter box, avoid birds from damaging the meter box, and ensure the normal operation of the meter box.

[0042] Among them, such as Figure 2As shown, a partition 12 is provided inside the housing 1. Partition 12 divides the interior of the housing 1 into a first accommodating chamber 13 and a second accommodating chamber 14. The first accommodating chamber 13 includes a mounting plate 15 and mounting rails 16. Mounting rails 16 are located below mounting plate 15. The energy meter 4 is mounted on mounting plate 15. The controller 5 is mounted on mounting rails 16. A main switch 6 is located in the second accommodating chamber 14. The main switch 6 is connected to the energy meter 4 via a connecting line 7.

[0043] In this embodiment, a partition 12 is provided inside the box 1 to divide the inside of the box 1 into different areas, optimizing the spatial layout. In this embodiment, a mounting plate 15 and mounting rails 16 are provided in the first accommodating cavity 13 to facilitate the installation and positioning of the energy meter 4 and the controller 5.

[0044] Among them, Figure 1 and Figure 2 As shown, the door 11 includes a first door 111 and a second door 112. The first door 111 is openably and closably disposed on the housing 1. When the first door 111 is closed, it covers the first accommodating cavity 13. The second door 112 is openably and closably disposed on the housing 1. When the second door 112 is closed, it covers the second accommodating cavity 14. When the first door 111 and the second door 112 are both closed, the first door 111 and the second door 112 can fit tightly together.

[0045] In this embodiment, Figure 1 As shown, the first door 111 and the second door 112 are respectively provided with handles 18 to facilitate opening and closing of the door 11 .

[0046] The box door 11 of this embodiment is a two-leaf structure, which covers the first accommodating cavity 13 and the second accommodating cavity 14 respectively. When the first box door 111 and the second box door 112 are in the closed state at the same time, the first box door 111 and the second box door 112 can fit tightly together, so it has good sealing performance and can provide good protection for the electronic components in the meter box.

[0047] Among them, Figure 1 As shown, the box door 11 is provided with a plurality of observation windows 17. The positions of the observation windows 17 correspond to the positions of the electric energy meter 4, the controller 5 and the main switch 6 respectively.

[0048] In this embodiment, a plurality of observation windows 17 are provided on the box door 11. The operator can check the operating status of the internal equipment of the meter box through these observation windows 17 without opening the box door 11, such as the reading of the energy meter 4, the working indicator light of the controller 5, the status of the main switch 6, etc., which is convenient for daily inspection and maintenance.

[0049] The above is a detailed introduction to the composite multifunctional outdoor electric meter box of this embodiment. The composite multifunctional outdoor electric meter box of this embodiment has multiple practical functions. The box body 1 cooperates with the box door 11 to provide a protective space inside. The observation window 17 on the box door 11 allows the operator to check the operating status of the internal equipment without opening the box door 11. The internal partition 12 optimizes the spatial layout. The fire extinguisher body 22 is installed in the fixed frame 21 through the cooperation of the block 26, the slot 24, the slide 252, and the limit block 253. This ensures that the fire extinguishing assembly 2 is stably placed in the box body 1 and can automatically activate the fire extinguishing when receiving a fire signal. The bird repellent assembly 3 is easy to install and prevents it from falling through the cooperation of the mounting rod 31, the elastic connecting plate 332 and the fixing ring 333, effectively preventing birds from entering the box body 1 and damaging the equipment. The fixing ring 333 squeezes and fixes the elastic connecting plate 332, further enhancing the stability of the installation of the bird repellent assembly 3, ensuring the normal operation of the electric meter box in terms of protection, fire prevention, and bird prevention, and improving its overall reliability and practicality.
