Description

Technical Field

[0001] The invention relates to the technical field of electric meter boxes, in particular to an intensive electric meter box for residential areas. Background Art

[0002] Most of the electric meters in residential buildings are located in intensive meter boxes in the electric well. The centralized design makes it convenient for electricians to inspect and repair the meters in the meter box.

[0003] The common intensive meter boxes on the market are partly of relatively sealed design and partly of non-sealed design. The former has almost no heat dissipation effect, while the latter only has a few heat dissipation holes at the bottom of the box, and the heat dissipation effect is also average. Especially in Wuhan, one of the four major furnaces where the applicant is located, the summer is now mostly in a high temperature environment for a long time. In summer, every family will use high-power air conditioners at home to cool down the indoor environment to ensure the comfort of the living environment. The electrical lines in the meter boxes that have been used for a long time will be aging. In summer, when residents use a lot of electricity, there will be a hidden danger of overheating of the wires and burning of the insulation sheath causing a fire. Especially in the summer nights when electricity consumption is at its peak, the wires are more likely to overheat. In order to ensure electricity safety, the power company will send electricians to inspect, repair and replace all meters after a certain period of time. The applicant's jurisdiction is the Wuhan East Lake New Technology Development Zone, which currently has an actual population of more than 4 million and an area of ​​600 square kilometers, with nearly 2 million meters. As the number of electricity users increases year by year, the burden on employees is getting heavier and heavier. How to reduce the failure rate of meters, extend the service life of meters, and replace meters conveniently is urgent. Of course, being able to replace meters without power outages is a very good choice for users. CN219392142U discloses an electric meter box structure which is convenient for replacing electric meters. When fixing the electric meter, the electric meter can be fixed and clamped by pressing the pressing handle of the fixing component. It is convenient and quick to use, but it must be carried out during a power outage. If the electric meter is replaced for users in the applicant's jurisdiction during a power outage in the hot summer, it will bring a bad experience to the users. Summary of the invention

[0019] The appearance of a concentrated electric meter box for residential areas provided by the present invention is as follows Figure 1 , Figure 2 As shown, it includes a box body 1, an air outlet 11 and an exhaust pipe 12 are opened on the top of the box body, the exhaust direction of the exhaust pipe 12 is horizontal, and an elongated air inlet 6 is opened at the bottom of the box body, and a filter 5 is installed on the air inlet 6.

[0020] like Figure 3 , Figure 4As shown, the box door of the box is opened, and the box 1 is provided with multiple groups of meter mounting racks 3 for mounting the meter 2. The mounting rack 3 can be an L-shaped rack fixed on the back plate of the box 1, and there can also be vertical plates on both sides of the L-shaped rack. An induced draft fan 4 is fixedly installed on the inner top wall of the box 1, and an induced draft fan 4 is arranged on the top of the inner wall of the box 1. The induced draft fan is connected to the exhaust pipe 12 through the air outlet 11 on the top wall of the box 1. A plurality of air guide plates 13 are arranged on the upper part of the box 1, and one end of the air guide plates is gathered and connected to the inlet of the induced draft fan 4, and the other end of the air guide plates 13 is dispersed to separate the upper part of the box 1 into a plurality of sections, so that the air in each part of the box can be evenly drawn out of the box when the induced draft fan draws air.

[0021] like Figure 5 As shown, the mounting frame 3 is provided with at least two groups of plug-in holes 1 35, plug-in posts 1 36 slidably arranged in the plug-in holes 1, plug-in holes 2 38, and plug-in posts 2 37 slidably arranged in the plug-in holes 2, one group is used to connect the live wire of the electric meter, and the other group is used to connect the neutral wire of the electric meter. The distance between the plug-in posts 1 36 and the plug-in posts 2 37 is consistent with the distance between the inlet and outlet holes of the same pole (such as the positive pole) on the electric meter. The plug-in posts 1 36 and the plug-in posts 2 37 are both provided with steps. The plug-in posts 1 36 and the plug-in posts 2 37 are used to insert the inlet and outlet holes of the electric meter. The plug-in hole 1 35 is connected to the incoming wire 7, and the plug-in hole 2 38 is connected to the outgoing wire 8. One group of incoming wires and outgoing wires is the live wire, and the other group of incoming wires and outgoing wires is the neutral wire. A bracket 39 is fixedly arranged on the mounting frame 3, the plug hole 1 35 and the plug hole 2 38 are fixedly arranged on the bracket 39, an intermediate conductor 33 is arranged between the plug hole 1 35 and the plug hole 2 38 and the mounting frame 3, and a spring 32 is also arranged between the intermediate conductor and the mounting frame 3, and an insulating column 34 is arranged on the intermediate conductor near the plug hole 1 and the plug hole 2, corresponding to the plug hole 1 and the plug hole 2, respectively, and the diameter of the insulating column is smaller than the diameter of the plug hole 1 and the plug hole 2. A limiting ring 31 is arranged on the mounting frame, and the spring is arranged in the limiting ring 31.

[0022] Working principle:

[0023] The blades of the induced draft fan 4 in the box body 1 rotate, forming wind flowing from bottom to top in the box body 1. The flowing wind enters through the air inlet 6, exchanges heat with the electric meter, wires, etc. in the box body, allowing the wind to take away the heat in the box body 1 and be discharged out of the box body through the air outlet 11. The filter 5 can prevent dust from entering the box body.

[0024] like Figure 5 As shown, in the initial state, the intermediate conductor 33 is connected to the first plug hole 35 and the second plug hole 38 under the thrust of the spring 32, so that the incoming line 7 and the outgoing line 8 are connected; Figure 6As shown, during the insertion process, align the wire inlet hole of the electric meter with the plug-in post 1 36 and the plug-in post 2 37, and press down with force to insert the plug-in post 1 and the plug-in post 2 into the wire inlet hole of the electric meter. When the wire inlet hole of the electric meter contacts the plug-in post 1 36 and the plug-in post 2 37, the incoming wire, the outgoing wire and the electric meter form a passage, and the plug-in post 1 36 and the plug-in post 2 37 are forced to push the middle conductor 33 downward, and the middle conductor 33 is separated from the plug-in hole 1 35 and the plug-in hole 2 38, and the plug-in post 1 36 and the plug-in post 2 37 are connected. An insulating column 34 is provided between the second plug-in column 37 and the middle conductor 33, so the incoming line 7 and the outgoing line 8 only form a passage through the electric meter to ensure accurate meter measurement. When the plug-in column 1 36 and the second plug-in column 37 continue to move downward, they are axially blocked by the limit ring 31. Even if the plug-in column 1 36 and the second plug-in column 37 have an interference fit with the inlet and outlet holes of the electric meter and require greater force to insert them, they can also obtain better force support to facilitate better insertion.
