[0003] During the use of smart meters, they may be overloaded for a long time, causing internal overheating or short circuit, poor heat dissipation, etc., which may cause the meter to self-ignite. The self-ignition of the meter is a serious safety issue. Although the air switch installed inside the meter will disconnect the circuit when the meter self-ignites, it only cuts off the power connection and cannot separate the meter from other devices. The wires connecting the meter and other devices can easily spread the fire to other devices, resulting in the risk of fire for the energy meter and other devices in the electrical box, which can easily cause greater economic losses.

This prevents the fire from spreading from the meter body to other devices, or when other devices catch fire, prevents the fire from spreading to the meter body.

[0018] 2. When the flame retardant component isolates the meter body from the outside world, start the fire extinguishing equipment and rotate the rotating ring at the same time, which is conducive to spraying the fire extinguishing dry powder evenly onto the meter body or onto the outside of the flame retardant component.

[0019] 3.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-Figure 16 The type of smart electricity meter shown has flameproof function.

[0040] Embodiment 1: The technical solution adopted by the present invention is as follows: A smart electric energy meter with flame retardant function includes a mounting plate 1 for mounting an electric meter body 9 and a flame retardant component. The electric meter body 9 is mounted on the mounting plate 1 by mounting bolts 12. A wire 10 is provided at the lower end of the electric meter body 9, and the electric meter body 9 is connected to other devices through the wire 10.

[0041] The mounting plate 1 is provided with a groove 14, in which a rotating ring 11 is rotatably mounted. The mounting plate 1 is provided with a first driving assembly for driving the rotating ring 11 to rotate. The first driving assembly includes a gear ring 2 and a gear 16. The gear ring 2 is coaxially fixedly connected to the rotating ring 11. The mounting plate 1 is provided with a third clearance groove 38, in which a first motor 15 is fixedly mounted, and the gear 16 is coaxially fixedly mounted on the motor shaft of the first motor 15, and the gear ring 2 and the gear 16 are meshed. The meter body 9 is located inside the rotating ring 11.

[0042] The flame retardant assembly includes a support rod and a diaphragm 3. A plurality of guide members are provided on the rotating ring 11 along its circumference for limited sliding. The plurality of guide members correspond to the plurality of support rods one by one, and one end of the support rod is rotatably provided on the corresponding guide member. Specifically, a first slide groove 8 is provided on the end face of the rotating ring 11, and a second slide groove 20 is provided on the inner wall of the first slide groove 8 on one side close to the axis of the rotating ring 11. The first slide groove 8 and the second slide groove 20 are both coaxially arranged with the rotating ring 11. The guide member includes a mounting block and a guide block 40, the guide block 40 is slidably arranged in the second slide groove 20, the mounting block is slidably arranged in the first slide groove 8, and the mounting block and the guide block 40 are fixedly connected. A fixing seat 18 is fixedly installed on each mounting block, and a second motor 23 is embedded and fixedly installed on the fixing seat 18. A first clearance groove 31 is provided on the end of each support rod close to the rotating ring 11, and a first rotating shaft 30 is fixedly installed in the first clearance groove 31. The fixing seat 18 extends into the first clearance groove 31 and the first rotating shaft 30 is fixedly connected to the motor shaft of the second motor 23 .

[0043] The support rod is arc-shaped, and the inner concave surface of the support rod faces the axis of the rotating ring 11. The intersection of the rotation trajectories of the ends of the multiple support rods away from the second motor 23 is located on the axis of the rotating ring 11. When the support rods rotate around the corresponding first rotating shaft 30 toward the direction close to the axis of the rotating ring 11, the ends of the multiple support rods away from the first rotating shaft 30 gather in the direction close to the axis of the rotating ring 11. A diaphragm 3 is connected between two adjacent support rods. The diaphragm 3 is elastic and made of fireproof material.

[0044] In this embodiment, for the convenience of description, the support rod at the head end of the flame retardant assembly is named the fourth support rod 7, and the support rod at the tail end of the flame retardant assembly is named the fifth support rod 13. The two support rods located between the fourth support rod 7 and the fifth support rod 13 are respectively named the first support rod 4 and the second support rod 5. The first support rod 4 and the second support rod 5 are adjacent. The other support rods are named the third support rod 6.

[0045] The fifth mounting block 39 corresponds to the fifth support rod 13 , the fourth mounting block 41 corresponds to the fourth support rod 7 , the first mounting block 25 corresponds to the first support rod 4 , the second mounting block 43 corresponds to the second support rod 5 , and the third mounting block 19 corresponds to the third support rod 6 .

[0046] The rotating ring 11 is provided with a second driving assembly for driving the flame retardant assembly to extend and retract.

[0047] The second driving assembly includes a rope 21, a winding wheel 22 and a spring 26. From the beginning to the end of the flame retardant assembly, a spring 26 is fixedly connected between two adjacent guide blocks 40. Under the action of the spring 26, the beginning and the end of the flame retardant assembly are against each other. Figure 6 , Figure 7 , Figure 8 As shown, two third motors 24 are fixedly embedded in the first slide groove 8, and the two third motors 24 are both located at the upper part of the rotating ring 11. A winding wheel 22 is coaxially fixedly connected to the motor shaft of each third motor 24, and a rope 21 is wound on each winding wheel 22. The free end of one of the ropes 21 slides to the left in sequence through multiple mounting blocks and is fixedly connected to the fifth mounting block 39, and the free end of the other rope 21 slides to the right in sequence through multiple mounting blocks and is fixedly connected to the fourth mounting block 41. The winding wheel 22 rotates to reel the rope 21, so that the fifth mounting block 39 and the fourth mounting block 41 are both moved to a position close to the middle of the flame retardant assembly, the spring 26 is compressed, and the multiple support rods are moved closer to the middle, and the flame retardant assembly shrinks. When the rope 21 is released, under the action of the spring 26, the fifth mounting block 39 and the fourth mounting block 41 slide outward, and the flame retardant assembly extends.

[0048] The width of the support rod gradually decreases from one end close to the second motor 23 to the other end, so that when the flame retardant component shrinks, two adjacent support rods can be completely fitted together.

[0049] The outer sides of the fourth support rod 7 and the fifth support rod 13 are fixedly mounted with cutting knives 17. The outer sides of the fourth support rod 7 and the fifth support rod 13 are provided with second clearance grooves 32. When the ends of the flame retardant assembly are pressed against each other, the cutting knives 17 on the fourth support rod 7 enter the second clearance grooves 32 on the fifth support rod 13, and the cutting knives 17 on the fifth support rod 13 enter the second clearance grooves 32 on the fourth support rod 7. When the two cutting knives 17 approach each other, the wires 10 are cut and cut off, thereby cutting off the connection between the electric meter body 9 and other devices.

[0050] A cleaning component is installed on the flame retardant component. The cleaning component cleans the meter body 9 to prevent a large amount of dust from accumulating on the outer surface of the meter body 9 and causing adverse effects. It also facilitates the staff to clearly observe the values ​​displayed on the display screen of the meter body 9. The cleaning component includes a storage case 33 and a brush 34. Fig.11 As shown, the storage shell 33 is fixedly mounted on the inner concave surface of the first support rod 4, and an opening is provided on the side of the storage shell 33 away from the first support rod 4. The upper end of the brush 34 is rotatably connected to the storage shell 33. Specifically, a second rotating shaft 37 is fixedly mounted on the upper end of the brush 34, and the second rotating shaft 37 is rotatably arranged on the upper end of the storage shell 33. A first torsion spring is sleeved on the second rotating shaft 37, and the first torsion spring is fixedly connected between the storage shell 33 and the brush 34. Under the action of the first torsion spring, the brush 34 is stored in the storage shell 33. The second rotating shaft 37 is perpendicular to the length direction of the storage shell 33.

[0051] A second connecting column 36 is fixedly mounted on one side of the storage shell 33, and the second connecting column 36 is perpendicular to the second rotation axis 37. The second connecting column 36 is rotatably mounted with a baffle 29, and the second connecting column 36 is sleeved with a second torsion spring, which is fixedly connected between the baffle 29 and the storage shell 33. Under the action of the second torsion spring, the baffle 29 blocks the opening of the storage shell 33.

[0052] The top of the brush 34 is fixedly connected to the first connection column 35. The second support rod 5 is fixedly mounted with an inclined surface block 28. The inclined surface block 28 cooperates with the first connection column 35. When the second support rod 5 approaches the first support rod 4, the inclined surface block 28 squeezes the first connection column 35, causing the brush 34 to rotate around the second rotation axis 37, and the brush 34 rotates out of the storage shell 33 and contacts the meter body 9. Then the rotating ring 11 is rotated, and the brush 34 is rotated around the axis of the rotating ring 11, and the rotating ring 11 cleans the outer surface of the meter body 9.

[0053] Working principle: Initially, Figure 1 As shown, the flame retardant assembly is located above the meter body 9 and is spread out at a certain angle. The flame retardant assembly protects the meter body 9 to reduce the aging speed of the outer shell of the meter body 9 and extend the service life of the meter body 9. The brush 34 is stored in the storage shell 33, and the baffle 29 blocks the opening of the storage shell 33 to protect the brush 34.

[0054] If the flame retardant component affects the maintenance of the meter body 9 in the initial state, multiple second motors 23 can be started at the same time to rotate the support rod upward, thereby moving the flame retardant component away from the meter body 9, making it easier to maintain the meter body 9. After the maintenance is completed, the motor shaft of the second motor 23 is rotated in the opposite direction to reset the support rod, so that the flame retardant component can better protect the meter body 9.

[0055] After using for a period of time, a large amount of dust will gather on the surface of the meter body 9, which is not conducive to the heat dissipation of the meter body 9 and affects the observation of the meter body 9. When the meter body 9 needs to be cleaned, the second motor 23 is first started to rotate the support rods toward the meter body 9 until the ends of the support rods away from the second motor 23 are gathered together.

[0056] Start the third motor 24, and the winding wheel 22 reels the rope 21, so that the fifth mounting block 39 and the fourth mounting block 41 move toward the upper part of the rotating ring 11 along the first slide groove 8, and then the multiple guide members move toward the upper part of the rotating ring 11, so that the flame retardant assembly shrinks and the adjacent support rods fit together. In the process of the second support rod 5 approaching the first support rod 4, the inclined block 28 acts on the first connecting column 35, so that the brush 34 rotates around the second rotating shaft 37, and the brush 34 pushes the baffle 29 to turn the baffle 29 outward, and then the brush 34 rotates to the outside of the storage shell 33 and gradually approaches the meter body 9. When the first support rod 4 and the second support rod 5 fit together, the brush 34 hits the front end surface of the meter body 9.

[0057] Afterwards, the first motor 15 is started, the gear 16 rotates, the gear ring 2 rotates, the rotating ring 11 rotates, the flame retardant component and the cleaning component rotate around the axis of the rotating ring 11, and the brush 34 cleans the front end surface of the meter body 9.

[0058] After cleaning is completed, the third motor 24 is started to release the rope 21. Under the action of the spring 26, the fifth support rod 13 and the fourth support rod 7 are moved outward, and the flame retardant assembly is gradually unfolded. When the flame retardant assembly is unfolded to a suitable angle, the third motor 24 is turned off. When the first support rod 4 and the second support rod 5 are far apart, under the action of the first torsion spring, the brush 34 rotates around the second rotating shaft 37 into the storage shell 33. When the brush 34 returns to the storage shell 33, the baffle 29 is reset under the action of the second torsion spring. Then the second motor 23 is started to rotate the support rod around the corresponding first rotating shaft 30 to a certain angle away from the meter body 9. Then, the rotating ring 11 is rotated through the first driving assembly so that the flame retardant assembly is directly above the meter body 9.

[0059] When the meter body 9 spontaneously ignites or other equipment catches fire, the second motor 23 is started to make the ends of the multiple support rods away from the second motor 23 gather toward the middle until the ends of the multiple support rods away from the second motor 23 gather together.

[0060] Then the third motor 24 is started to pay out the rope 21. Under the action of the spring 26, the adjacent support rods move away from each other, and the fourth support rod 7 and the fifth support rod 13 gradually approach each other until the cutting knife 17 contacts the wire 10, cutting the wire 10 and disconnecting the meter body 9 from other devices. Then the fourth support rod 7 and the fifth support rod 13 collide, and the cutting knife 17 is inserted into the corresponding second motor 23.

[0061] At this time, the flame retardant component completely covers the meter body 9, isolating the meter body 9 from the outside.

[0062] Prevent the fire in the meter body 9 from spreading to other devices along the wire 10 and causing damage to other devices. If other devices catch fire, prevent the fire from spreading to the meter body 9 and protect the meter body 9.

[0063] The storage shell 33 and the baffle 29 are both made of fireproof materials. The brush 34 is stored in the storage shell 33, which has a protective effect on the brush 34 and prevents the brush 34 from catching fire and increasing the fire.

[0064] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1, and only the different parts from Embodiment 1 are introduced.

[0065] A plurality of first spray holes 27 are provided on the inner side of each support rod, and a plurality of second spray holes 42 are provided on the outer side of each support rod. A first channel and a second channel are provided inside the support rod, and the first channel and the second channel are both connected to an external fire extinguishing device for spraying fire extinguishing dry powder. The output end of the fire extinguishing device is connected to the first channel or the second channel through a hose. The first spray hole 27 is connected to the first channel. The second spray hole 42 is connected to the second channel.

[0066] If a fire occurs in the meter body 9, the fire extinguishing device is started, and the fire extinguishing dry powder in the fire extinguishing device enters the first channel, and then is sprayed out through the first spray hole 27 and sprayed toward the meter body 9. At the same time, the first motor 15 is started to rotate the flame retardant component around the axis of the rotating ring 11, and the fire extinguishing dry powder is evenly sprayed onto the meter body 9, thereby comprehensively extinguishing the fire of the meter body 9, which is conducive to timely control of the fire.

[0067] If other equipment catches fire, the fire extinguishing equipment is started, and the fire extinguishing dry powder in the fire extinguishing equipment is sprayed out through the second spray hole 42 to control the fire outside the flame retardant component. At the same time, the first motor 15 is started, the rotating ring 11 rotates, and the flame retardant component rotates, so that the fire outside the flame retardant component can be fully extinguished to prevent the fire from spreading.

[0068] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
