The outer side of the clamp ring 5 is provided with a screw nut 51, and the front side of the top of the electric energy metering box body 1 is connected to a smoke sensor 121. The inside of the connecting block 4 is rotatably connected to an electric sprinkler 6, and water can be sprayed out to extinguish the fire through the electric sprinkler 6. The electric sprinkler 6 and the smoke sensor 121 are electrically connected through a control module, and the bottom of the electric sprinkler 6 and the bottom of the water tank 2 are connected. Hose 8, a filter screen 7 is provided on the upper part of the water tank 2, people can also pour waste water through the top of the water tank 2, and the waste water can be filtered through the filter screen 7, so that the purpose of waste water recycling can be achieved. A distance mechanism for keeping the power meter box away from other nearby power equipment is provided at the bottom of the power meter box body 1; the distance mechanism includes a support seat 9, a connecting piece 10, a rack 11, a first motor 12, a first gear 13 and a protective shell 14, and connecting pieces 10 are welded on both sides of the bottom of the support seat 9, and a rack 11 is welded on the rear part of the support seat 9. The first motor 12 is connected to the output shaft of the first motor 12 through a coupling. The first gear 13 and the rack 11 are meshed, and the smoke sensor 121 and the first motor 12 are electrically connected through the control module. A protective shell 14 is provided in the middle of the bottom of the power meter box body 1, and the protective shell 14 covers the outside of the first motor 12, and the protective shell 14 can prevent the first motor 12 from fire.

[0031] The safety and fireproof electric energy meter box used in the dry environment can be installed between two electric poles. Before installing the safety and fireproof electric energy meter box used in the dry environment, it is necessary to use a mounting frame to first fix it between the two electric poles, and then install the support seat 9 on the mounting frame. The connecting piece 10 can be fixed to the mounting frame by bolts, and other power equipment can be installed on the upper left part of the support seat 9. Then, the lines of other power equipment and the line connecting part need to be connected. When connecting, the line connecting piece 101 of other power equipment needs to be put on the upper position of the line connecting part, and then a nut is used to put on the upper part of the line connecting part, and the nut is rotated to clamp the line connecting piece 101 of other power equipment on the line through the nut. The electric energy meter box body 1 and the electric energy meter box body 2 are connected to each other by the electric power supply, and the electric energy meter box body 1 is connected to the electric energy meter box body 1. The electric energy meter box body 1 is connected to the electric energy meter box body 1 by the electric power supply, and the ... The electric equipment nearby can also be sprayed. After adjusting the installation position of the electric sprinkler 6, the screw nut 51 can be reinstalled into the clamp ring 5. In this way, the clamp ring 5 can fix the electric sprinkler 6 on the electric pole. During the operation of the electric energy meter box body 1, if the electric energy meter box body 1 is on fire, when the smoke sensor 121 detects smoke, it will control the electric sprinkler 6 to work. The electric sprinkler 6 can spray water onto the electric energy meter box body 1 to extinguish the fire. At the same time, the water can also extinguish the fire of the electric equipment around the electric energy meter box body 1 to avoid damage to other electric equipment due to excessive fire. At the same time, the first motor 12 automatically stops working after 3 seconds of starting to work. The output shaft of the first motor 12 rotates to drive the first gear 13 to rotate. With the cooperation between the rack 11 and the first gear 13, the first gear 13 can move to the right along the rack 11, thereby driving the power meter box body 1 to move to the right. In this way, the power meter box body 1 can be away from the power equipment on the left, thereby preventing the fire from spreading to the power equipment on the left, which can improve the fire prevention effect. When the fire is extinguished, the smoke sensor 121 does not detect smoke, then the electric sprinkler 6 will be controlled to stop working, and the output shaft of the first motor 12 will reverse and automatically stop working after 3 seconds. The output shaft of the first motor 12 drives the first gear 13 to reverse, thereby driving the power meter box body 1 to move to the left and reset.

[0032] Embodiment 2: Based on embodiment 1, Figure 5-Figure 6As shown, it also includes a fixing frame 15, a contact rod 16, a guide rod 17, a first spring 18, a contact plate 19 and an ejection assembly. The fixing frame 15 is fixedly connected to the upper rear part of the support seat 9, and a protrusion is provided on the upper right part of the fixing frame 15. The left and right sides of the upper rear part of the electric energy meter box body 1 are connected to the guide rods 17, and the contact plates 19 are slidably connected between the guide rods 17. The contact plates 19 cooperate with the line connection part of the electric energy meter box body 1. The left and right sides of the bottom of the contact plate 19 and the electric energy meter box body 1 are connected to the first spring 18. The spring 18 is wound on the guide rod 17, and the contact rod 16 is fixedly connected to the middle of the rear part of the contact plate 19. The contact rod 16 and the protrusion of the fixing frame 15 are squeezed together. An ejection component for ejecting the line connecting piece 101 upward is provided between the upper part of the line connecting part of the electric energy meter box body 1; the ejection component includes an ejection piece 20 and a second spring 21, and the upper parts of the three line connecting parts are all slidably connected with the ejection piece 20, the contact plate 19 and the ejection piece 20 are squeezed together, and the second spring 21 is connected between the bottom of the ejection piece 20 and the line connecting part.

[0033] In the process of connecting the electric energy meter box body 1 and the lines of other electric equipment together, it is necessary to manually turn the nut to clamp the line connecting piece 101 of other electric equipment on the line connecting part. If the electric energy meter box body 1 is on fire, the fire can easily spread to other electric equipment through the line connecting piece 101 of other electric equipment. In order to avoid the above problem, a contact plate 19 and a ejection assembly are provided. Before connecting the line connecting part of the electric energy meter box body 1 and the line connecting piece 101 of other electric equipment, the contact plate 19 can be manually pulled upwards. The first spring 18 is stretched to separate the contact plate 19 from the line connecting part. At this time, the contact plate 19 moves upwards. The ejector 20 will be released, and the second spring 21, which was originally in a compressed state, will drive the ejector 20 to move upward. Then, people can manually put the line connecting piece 101 of other power equipment on the upper position of the line connection part, and press the line connecting piece 101 downward with force. The line connecting piece 101 will contact the ejector 20 and drive the ejector 20 to move downward. The second spring 21 is compressed, and then the contact plate 19 is released. Under the action of the first spring 18, the contact plate 19 will move downward and contact the top of the line connecting piece 101. Since the elastic force of the first spring 18 is greater than that of the second spring 21, the contact plate 19 will continue to squeeze the line connecting piece 101, so that the line connecting piece 1 01 drives the ejector 20 to move downward, and the second spring 21 continues to be compressed. In this way, the line connecting piece 101 can be fixed on the line connecting part of the electric energy meter box body 1 under the cooperation between the ejector 20 and the contact plate 19. If a fire occurs later, the electric energy meter box body 1 will move to the right and drive the contact plate 19 and the contact rod 16 to move to the right. When the contact rod 16 contacts the raised position of the fixing frame 15, the contact rod 16 is pushed upward by the raised position, and the contact rod 16 drives the contact plate 19 to move upward. The first spring 18 is stretched again, and the contact plate 19 moves upward to release the line connecting piece 101. At this time, under the action of the second spring 21, the ejector 20 will be driven. 0 moves upward to push out the line connecting piece 101, and the line connecting piece 101 will automatically separate from the line connecting part of the electric energy meter box body 1. In this way, it is possible to automatically disconnect the line connecting piece 101 of other power equipment from the line connecting part of the electric energy meter box body 1 in the event of a fire, so as to prevent the fire from spreading through the line connecting piece 101. When the electric energy meter box body 1 moves to the left and resets, it will drive the contact plate 19 and the contact rod 16 to move to the left. After the contact rod 16 moves to the left and slowly separates from the protrusion, under the action of the first spring 18, it will drive the contact plate 19 to move downward and reset, and the contact plate 19 drives the ejector 20 to move downward and reset, and the second spring 21 is compressed.

[0034] like Figure 7As shown, it also includes a second motor 201, a second gear 22 and a third gear 23. The second motor 201 is connected to the connecting block 4 by bolts, the second motor 201 and the smoke sensor 121 are electrically connected through a control module, the output shaft of the second motor 201 is connected to the second gear 22 through a coupling, the electric sprinkler 6 is connected to the third gear 23, and the second gear 22 and the third gear 23 are meshed.

[0035] In order to speed up fire extinguishing, a second motor 201 is provided. When the smoke sensor 121 detects smoke, the output shaft of the second motor 201 is controlled to rotate back and forth. The output shaft of the second motor 201 drives the second gear 22 and the third gear 23 to rotate forward and backward. The third gear 23 drives the electric sprinkler head 6 to swing forward and backward continuously. The forward and reverse swing angle of the electric sprinkler head 6 is 60 degrees. In this way, the electric sprinkler head 6 can expand the water spraying range and speed up fire extinguishing. When the smoke sensor 121 does not detect smoke, the second motor 201 automatically stops working.

[0036] like Figure 8 As shown, it also includes an elastic telescopic member 24, a shielding cover 25, a shielding plate 26 and an extrusion rod 27. The elastic telescopic member 24 is connected to the left and right sides of the top of the electric energy meter box body 1. A shielding cover 25 is connected between the tops of the elastic telescopic member 24. The shielding cover 25 is used to cover the top of the electric energy meter box body 1 to keep out rain. The shielding plates 26 are connected to the left and right sides of the bottom of the shielding cover 25. The shielding plates 26 are used to block the heat dissipation holes on the left and right sides of the electric energy meter box body 1. An extrusion rod 27 is welded to the upper right part of the fixing frame 15, and the bottom of the extrusion rod 27 and the top of the shielding cover 25 are squeezed together.

[0037] When the electric energy meter box body 1 catches fire, the electric nozzle 6 sprays water on the electric energy meter box body 1, and the water may be sprayed into the electric energy meter box body 1 through the heat dissipation holes. If a large amount of water enters the electric energy meter box body 1, some components inside the electric energy meter box body 1 that were not originally on fire will easily burn out. Therefore, when the electric energy meter box body 1 moves to the right, it will drive the elastic telescopic member 24, the shielding cover 25 and the shielding plate 26 to move to the right. When the top of the shielding cover 25 contacts the squeezing rod 27, the squeezing rod 27 will squeeze the shielding cover 25 downward, the elastic telescopic member 24 is compressed, and the shielding cover 25 moves downward, which will drive the shielding plate 26 to move downward as well. The shielding plate 26 can block the heat dissipation holes on both sides of the electric energy meter box body 1, which can Secondly, it can isolate the inside of the electric energy meter box body 1 from the outside air, so that when the inside of the electric energy meter box body 1 is on fire, after the oxygen inside the electric energy meter box body 1 is consumed, the fire inside the electric energy meter box body 1 will automatically gradually shrink and disappear. Secondly, it can prevent water from entering the inside of the electric energy meter box body 1. If the fire point is not inside the electric energy meter box body 1, blocking the heat dissipation holes by the baffle plate 26 can prevent water from infiltrating and causing the internal components of the electric energy meter box body 1 to burn out. When the electric energy meter box body 1 moves to the left, it drives the elastic telescopic member 24, the shielding cover 25 and the shielding plate 26 to move to the left and reset. When the top of the shielding cover 25 is separated from the extrusion rod 27, under the action of the elastic telescopic member 24, the shielding cover 25 and the shielding plate 26 are driven to move upward and reset.

[0038] like Figure 8-Figure 9 As shown, it also includes a support member 28, a slider 29, a telescopic rod 30 and a clamping ring 31. The upper left portion of the fixed frame 15 is connected to the support member 28, and three sliders 29 are slidably connected to the upper portion of the support member 28. The tops of the sliders 29 are all connected to the telescopic rods 30, and the tops of the telescopic rods 30 are all connected to the clamping rings 31.

[0039] When the electric energy meter box body 1 and the lines of other electric equipment are connected, the lines of other electric equipment can be clamped on the upper part of the clamping ring 31, and the position of the clamping ring 31 and the height of the clamping ring 31 can be adjusted forward and backward according to the position of the lines. When the front and rear position of the clamping ring 31 is adjusted, the telescopic rod 30 and the slider 29 will be driven to move forward and backward, and when the height of the clamping ring 31 is adjusted, the telescopic rod 30 will telescope, thereby avoiding clutter in the lines of other electric equipment.

[0040] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
