[0039] Among them, the heat dissipation component 002 arranged in the meter housing 001 includes a back frame plate 201, and a plurality of through cavities 202 are sequentially opened downward on the inner wall of the back frame plate 201. An upper grid plate 204 is arranged above the back frame plate 201, and a lower grid plate 205 is arranged below the back frame plate 201. The gaps inside the upper grid plate 204 and the lower grid plate 205 are connected with the through cavities 202 at corresponding positions.

[0040] The heat in the meter housing 001 can be discharged through the upper grid plate 204, the lower grid plate 205 and the through cavity 202, and when the upper grid plate 204 and the lower grid plate 205 are close to each other, the gap between the upper grid plate 204 and the lower grid plate 205 is misaligned with the through cavity 202, so that the through cavity 202 is sealed and loses its heat dissipation effect, and when the upper grid plate 204 and the lower grid plate 205 are away from each other, they can also be misaligned with the through cavity 202.

[0041] Furthermore, the heat dissipation component 002 also includes a slide groove 203, which is symmetrically opened on the inner wall of the back frame plate 201, and sliders 206 are symmetrically installed on both sides of the upper grille plate 204 and the lower grille plate 205, and the sliders 206 are slidably connected to the corresponding slide grooves 203; through the cooperation of the sliders 206 and the slide grooves 203, the upper grille plate 204 and the lower grille plate 205 can slide in the back frame plate 201.

[0042] In the above structure, a plurality of electric push rods 207 are installed between the upper grid plate 204 and the lower grid plate 205, touch blocks 208 are installed on the outer sides of the sliders 206 on both sides of the upper grid plate 204, and touch buttons 209 are symmetrically installed on the inner wall of the meter housing 001, and the touch buttons 209 and the touch blocks 208 are arranged opposite to each other; through the sliding of the upper grid plate 204, the touch blocks 208 can contact with the touch buttons 209.

[0043] Furthermore, a controller 210 is installed on the inner wall of the meter housing 001, and the controller 210 is electrically connected to the electric push rod 207 and the touch button 209, and the controller 210 is electrically connected to the cooling fan 104; the controller 210 can control the movement of the electric push rod 207 to make the electric push rod 207 work, and the controller 210 can control the cooling fan 104 to work.

[0044] The protection component 003 arranged in the meter housing 001 includes a guide ring 301, which is symmetrically installed on both sides of the lower grid plate 205. The two sets of guide rings 301 are connected with electric plug rods 302, and the electric plug rods 302 are electrically connected to the meter instrument 103. Sockets 305 are symmetrically installed on the inner wall of the meter housing 001, and the sockets 305 are electrically connected to the outside world, and the sockets 305 are plugged into the electric plug rods 302.

[0045] The guide ring 301 can be used to make the lower grid plate 205 slide upward, and at this time, the guide ring 301 slides along the electric plug rod 302; when the lower grid plate 205 moves downward, the guide ring 301 can drive the electric plug rod 302 to move downward, so that the electric plug rod 302 is disengaged from the socket 305, thereby cutting off the power to the electric meter 103, thereby completing the power off in case of fire or safe power off during maintenance.

[0046] Furthermore, the protection component 003 also includes a limit ring 303, which is sleeved and fixed on the electric plug rod 302, and a spring 304 is sleeved on the electric plug rod 302, and the two sides of the spring 304 are respectively fitted with the limit ring 303 and the guide ring 301, a through groove 306 is opened on one side of the lower grid plate 205, and a connecting hole 307 is opened below the inner wall of the through groove 306, a push cylinder 308 is slidably connected through the connecting hole 307, and the push cylinder 308 is slidably limited with the connecting hole 307; the spring 304 can make the electric plug rod 302 firmly fixed inside the socket 305, and the push cylinder 308 can slide up and down along the connecting hole 307.

[0047] In the above structure, a spring 2 309 is fittedly connected between the push cylinder 308 and the connecting hole 307, a push frame 310 is installed above the push cylinder 308, a baffle 311 is installed above the push frame 310, a through slot 2 312 is opened at the lower part of the inner wall of the through cavity 202 near the through slot 1 306, and the through slot 2 312 is connected to the through slot 1 306.

[0048] By sliding the push cylinder 308 in the connecting hole 307, the push frame 310 can be in the through groove 1 306 or the through groove 2 312, so that the upper grid plate 204 and the lower grid plate 205 can avoid interference with the push frame 310 during the movement, and the spring 2 309 can ensure that the position of the baffle 311 is fixed, and when the upper grid plate 204 and the lower grid plate 205 are moving away from each other, the baffle 311 can move with them, so that the baffle 311 closes the through cavity 202.

[0049] Furthermore, guide grooves 315 are symmetrically provided on the inner wall of the through cavity 202, guide blocks 316 are symmetrically installed on both sides of the baffle 311, and the guide blocks 316 are slidably connected with the corresponding guide grooves 315; a baffle 311 structure is also provided below the upper grid plate 204 and above the lower grid plate 205; through the cooperation of the guide blocks 316 and the guide grooves 315, the baffle 311 can slide more smoothly in the through cavity 202.

[0050] A touch block 2 313 is installed on the outer side of the slider 206 above the upper grid plate 204, and a touch button 2 314 is symmetrically installed on the inner wall of the meter housing 001, and the touch button 2 314 and the touch block 2 313 are arranged opposite each other; the touch button 2 314 is electrically connected to the controller 210, and the touch button 2 314 is electrically connected to the background control center of the meter instrument 103, and a temperature detector 317 is installed on the inner wall of the meter housing 001, and the temperature detector 317 is electrically connected to the controller 210.

[0051] The temperature and whether a fire occurs can be monitored in real time through the temperature sensor 317, so that the controller 210 controls the electric push rod 207, so that the upper grid plate 204 and the lower grid plate 205 are moved away from each other, and the touch block 2 313 and the touch button 2 314 are coordinated. When the touch button 2 314 is touched, the background can receive a fire alarm signal, and the upper grid plate 204 and the lower grid plate 205 are moved away from each other to seal the inside of the meter housing 001, reduce oxygen, and prevent the fire from further spreading to the outside.

[0052] The fixed component 004 arranged in the meter housing 001 includes a toggle rod 402, which is symmetrically arranged above the upper grid plate 204, and the toggle rod 402 is also symmetrically arranged below the lower grid plate 205. Each group of toggle rods 402 is fitted with a fixing rod 404 on one side away from the upper grid plate 204 and the lower grid plate 205, and each group of fixing rods 404 is connected to the corresponding fixing seat 102.

[0053] The upper grid plate 204 pushes the toggle rod 402 to move, so that the toggle rod 402 pushes the fixing rod 404 to move into the fixing seat 102, so that the fixing seat 102 can be fixed to the installation position of the electric meter.

[0054] Furthermore, the fixing component 004 also includes a docking hole 401, which is symmetrically opened above the upper grille plate 204, and a docking hole 401 is also symmetrically opened below the lower grille plate 205, a limiting ring 2 403 is fixedly sleeved on the toggle rod 402, the toggle rod 402 is limitedly connected to the docking hole 401, a spring 3 406 is fitted between the docking hole 401 and the toggle rod 402, a toggle groove 405 is opened on the surface of the back frame plate 201, and the toggle groove 405 and the toggle rod 402 are at the same horizontal position.

[0055] The toggle slot 405 can be used to displace the toggle rod 402 and squeeze the spring three 406, so that the fixing rod 404 can be displaced in the fixing seat 102, so that the meter housing 001 can be disassembled as a whole, and the continuous toggle of the toggle rod 402 can make the back frame plate 201 disassembled as a whole; due to the action of the spring three 406, the position of the fixing rod 404 will not be disturbed during the movement of the upper grid plate 204 and the lower grid plate 205, thereby ensuring the stability of the installation of the back frame plate 201 and the meter housing 001.

[0056] Working principle: The temperature inside the meter housing 001 can be monitored in real time through the temperature sensor 317. When the temperature is high, the upper grid plate 204 and the lower grid plate 205 are driven by the electric push rod 207 to move closer to each other, so that the gap between the two is moved to a position flush with the through cavity 202. At the same time, the touch block 208 contacts the touch button 209, so that the cooling fan 104 works to actively dissipate the internal heat. In the environment of normal temperature or low temperature at night, the upper grid plate 204 and the lower grid plate 205 will reset and close the through cavity 202 to prevent dust from entering; when the temperature sensor 317 detects a fire, the electric push rod 207 can drive the upper grid plate 204 and the lower grid plate 205 to move in opposite directions, so that the upper grid plate 204 and the lower grid plate 205 move and drive the two sets of baffles 311 to move, so that the through cavity 202 of the back frame plate 201 is sealed, and the touch block 2 313 and the touch button 2 314 are in contact, so that the touch button 2 314 transmits the alarm signal to the background control center, and at the same time, the electric plug rod 302 is moved from The socket 305 is detached to complete the power off; due to the sealing of the meter housing 001, the risk of fire spreading can be further reduced, and the power can be cut off in advance for the entire meter during maintenance and disassembly, ensuring the safety during maintenance; and due to the movement of the upper grid plate 204 and the lower grid plate 205, the position of the toggle rod 402 and the fixing rod 404 is maintained, thereby ensuring the overall installation stability of the back frame plate 201 and the meter housing 001, and the disassembly can be completed by moving the toggle rod 402; through this structure, The meter housing 001 can actively dissipate heat to the outside and provide a certain degree of protection against dust. The upper grid plate 204 and the lower grid plate 205 can move toward each other to disconnect the electric plug rod 302 and the socket 305, thereby achieving timely power off and active alarm prompts during maintenance or fire. The upper grid plate 204 and the lower grid plate 205 can still be sealed in this state to prevent further spread of the fire. The meter housing 001 and the back frame plate 201 can be disassembled together to facilitate daily repair and maintenance.
