[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0020] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0021] As Figures 1-11 shown, an electrical fire alarm and monitoring device includes a residual current type electrical fire monitoring detector 1. Dust-proof mechanisms 2 are arranged on both sides of the residual current type electrical fire monitoring detector 1. The dust-proof mechanisms 2 are used to prevent dust from entering the interior of the residual current type electrical fire monitoring detector 1. Dust-removing mechanisms 3 are arranged at the bottoms of both sides of the residual current type electrical fire monitoring detector 1. The dust-removing mechanisms 3 can be used to clean the dust-proof mechanisms 2. A mounting mechanism 4 is arranged outside the dust-removing mechanisms 3. The mounting mechanism 4 is used to quickly mount the residual current type electrical fire monitoring detector 1.

[0022] The dust-proof mechanism 2 includes two sliding rails 201. The sliding rails 201 provide sliding positions and mounting positions. One side of the four sliding rails 201 is fixedly connected to the upper and lower ends on both sides of the residual current type electrical fire monitoring detector 1 respectively. A sliding bar 202 is slidably connected inside the sliding rail 201. The sliding bar 202 and the sliding rail 201 cooperate to serve as the basis for installation and sliding. A plurality of receiving grooves 203 are formed inside the sliding bar 202. The receiving grooves 203 provide sliding positions. A pressing spring 204 is arranged inside the receiving groove 203. A limiting round block 205 is slidably connected inside the receiving groove 203. The limiting round block 205 has a limiting function. A movable rod 206 is fixedly connected to the side of the limiting round block 205 away from the pressing spring 204. The movable rod 206 serves as a connection. A filter plate 207 is fixedly connected between a plurality of movable rods 206. The pressing spring 204 can pull the limiting round block 205 and the movable rod 206 to move towards the direction of the residual current type electrical fire monitoring detector 1, and then the filter plate 207 can be made to closely adhere to the heat dissipation holes of the residual current type electrical fire monitoring detector 1. A toothed plate 208 is fixedly connected to the bottom of the upper sliding bar 202. A through groove 209 is formed at the bottom of the upper sliding rail 201. The through groove 209 does not prevent the movement of the toothed plate 208. The toothed plate 208 is slidably connected inside the through groove 209. A limiting groove 210 is formed at the top of the sliding bar 202. A limiting block 211 is fixedly connected to the inner top of the sliding rail 201. The cooperation between the limiting groove 210 and the limiting block 211 can prevent the sliding bar 202 from completely moving out of the inside of the sliding rail 201. The limiting block 211 is slidably connected inside the limiting groove 210. Rotating shafts 212 are rotatably connected to the inner sides of both sides of the residual current type electrical fire monitoring detector 1. The rotating shafts 212 have the functions of installation and rotation. A gear 213 is fixedly connected to the top of the rotating shaft 212. A cleaning roller brush 214 is fixedly connected to the outside of the rotating shaft 212. The movement of the toothed plate 208 can drive the gear 213 to rotate, and then drive the rotating shaft 212 and the cleaning roller brush 214 to rotate, and then can play a role in cleaning the filter plate 207. The gear 213 and the toothed plate 208 are meshed. One end of the pressing spring 204 is fixedly connected inside the receiving groove 203, and the other end of the pressing spring 204 is fixedly connected to the side of the limiting round block 205 away from the movable rod 206. A pull handle 215 is fixedly connected between the upper and lower sliding bars 202. The movable rod 206 penetrates through the inside of the sliding bar 202. When dust enters the residual current type electrical fire monitoring detector 1, it will be blocked by the filter plate 207, and then the dust can be prevented from entering the inside of the residual current type electrical fire monitoring detector 1. When the filter plate 207 needs to be cleaned, the pull handle 215 is pulled outwards, and then the sliding bar 202 can be driven to move towards the outside of the sliding rail 201, and then the toothed plate 208 can be driven to move outwards. At the same time, the filter plate 207 will also move outwards.When the toothed plate 208 moves outward, it can drive the gear 213 to rotate. After the gear 213 rotates, it can drive the rotating shaft 212 to rotate. When the rotating shaft 212 rotates, it can drive the cleaning roller brush 214 to rotate. When the filter plate 207 contacts the outside of the cleaning roller brush 214, the cleaning roller brush 214 will squeeze the filter plate 207 outward. At this time, the abutting spring 204 will provide a pulling force to pull the limiting round block 205 towards the direction close to the residual current type electrical fire monitoring detector 1. Subsequently, the movable rod 206 can be subjected to a pulling force towards the residual current type electrical fire monitoring detector 1. Therefore, the filter plate 207 can be closely attached to the outside of the cleaning roller brush 214. Similarly, when the filter plate 207 is located at the heat dissipation holes on both sides of the residual current type electrical fire monitoring detector 1, it will also be subjected to the pulling force of the abutting spring 204, making the filter plate 207 closely attached to both sides of the residual current type electrical fire monitoring detector 1 to prevent dust from entering the gap. When the cleaning roller brush 214 rotates, the cleaning roller brush 214 can clean the filter plate 207.,

[0023] The dust removal mechanism 3 includes an installation curved rod 301 which provides an installation function. The bottoms of the two installation curved rods 301 are respectively fixedly connected to the bottom sides of the residual current type electrical fire monitoring detector 1. The outer top end of the installation curved rod 301 is rotatably connected with a rotating outer sleeve 302. The rotating outer sleeve 302 can rotate on the outer top end of the installation curved rod 301. A torsion spring 303 is arranged inside the rotating outer sleeve 302. The outer part of the rotating outer sleeve 302 is fixedly connected with a knocking rod 304. Under the action of the torsion spring 303, it can drive the knocking rod 304 to reset. The bottom side of one side of the filter plate 207 is fixedly connected with a groove plate 305. The torsion spring 303 can drive the rotating outer sleeve 302 to reset and then can use the knocking rod 304 to knock the groove plate 305, making the groove plate 305 vibrate. Subsequently, the dust on the filter plate 207 will fall. One end of the torsion spring 303 is fixedly connected to the inside of the rotating outer sleeve 302, and the other end of the torsion spring 303 is fixedly connected to the outside of the installation curved rod 301. The torsion spring 303 is sleeved on the outside of the installation curved rod 301. The knocking rod 304 is in contact with the groove plate 305. When the filter plate 207 moves outward, it drives the groove plate 305 to move outward. When the groove on the groove plate 305 moves to one side of the knocking rod 304, under the action of the torsion spring 303, it drives the rotating outer sleeve 302 to rotate. Subsequently, it can drive the knocking rod 304 to move towards the groove of the groove plate 305. When the knocking rod 304 moves out of the groove of the groove plate 305, it will drive the knocking rod 304 to rotate. Subsequently, it can compress the torsion spring 303. Therefore, the knocking rod 304 continuously moves in and out of the groove of the groove plate 305, making the knocking rod 304 knock the groove plate 305. Subsequently, the vibration generated on the groove plate 305 can be transmitted to the filter plate 207. Subsequently, the dust on the filter plate 207 will fall. Cooperating with the cleaning roller brush 214 can play a role in cleaning the filter plate 207.,

[0024] The installation mechanism 4 includes an installation slide plate 401. One side of the installation slide plate 401 is fixedly connected to the outside of the residual current type electrical fire monitoring detector 1. Two placement grooves 402 are formed inside the installation slide plate 401. The placement grooves 402 can provide a sliding space. A rotating core 403 is rotatably connected inside the installation slide plate 401. A return spring 404 is arranged inside the placement groove 402. A limiting circular plate 405 is slidably connected inside the placement groove 402. One end of the limiting circular plate 405 away from the return spring 404 is fixedly connected with a clamping head 406. The return spring 404 can drive the limiting circular plate 405 and the clamping head 406 to reset. An installation base 407 is arranged outside the installation slide plate 401. An installation groove 408 is formed inside the installation base 407. After the installation slide plate 401 slides into the installation groove 408, the installation slide plate 401 can be installed on the installation base 407. The outside of the installation slide plate 401 is slidably connected inside the installation groove 408. Clamping holes 409 are formed on both the upper and lower sides inside the installation base 407. The clamping head 406 is engaged with the clamping holes 409. After the clamping holes 409 and the clamping head 406 are engaged, it can prevent the installation slide plate 401 from sliding out of the installation groove 408. One side of the limiting circular plate 405 close to the rotating core 403 is fixedly connected with a steel rope. The steel rope can be wound up when the rotating core 403 rotates, and drive the limiting circular plate 405 and the clamping head 406 to move towards the middle. One side of the steel rope is fixedly connected to the outside of the rotating core 403. One end of the return spring 404 is fixedly connected inside the placement groove 402. The other end of the return spring 404 is fixedly connected to one end of the limiting circular plate 405 away from the clamping head 406. A screwing round handle 410 is fixedly connected to the outside of the rotating core 403. An anti-slip sleeve is sleeved on the outside of the screwing round handle 410. When installing the residual current type electrical fire monitoring detector 1, first, the installation base 407 is fixed inside places such as a distribution box or a power distribution room through the holes on the installation base 407 by bolts. At this time, then slide the installation slide plate 401 into the installation groove 408. When the clamping head 406 is about to enter the installation groove 408, rotate the screwing round handle 410, and then it can drive the rotating core 403 to rotate, thereby driving the steel rope to rotate towards the middle, and then it can pull the limiting circular plate 405 towards the middle, and then drive the clamping head 406 to move towards the middle. When the clamping head 406 enters the placement groove 402, slide the installation slide plate 401 into the installation groove 408 again and completely slide into the installation groove 408. When the clamping head 406 moves to the clamping hole 409, release the screwing round handle 410. Under the action of the return spring 404, it drives the limiting circular plate 405 to move outwards, and then it can make the clamping head 406 slide into the clamping hole 409 to complete the installation of the residual current type electrical fire monitoring detector 1. When disassembling, rotate the screwing round handle 410 again, and then it can drive the steel rope to wind up towards the middle, and then it can make the clamping head 406 move towards the inside of the placement groove 402.At this time, after sliding the installation slide plate 401 out of the interior of the installation groove 408, the residual current type electrical fire monitoring detector 1 can be detached from the installation base 407. Therefore, if the installation base 407 is installed inside a distribution box or a power distribution room, etc., there is no need to detach the installation base 407 again. Subsequently, when installing the residual current type electrical fire monitoring detector 1 again later, there is no need to use bolts for installation.

[0025] Working principle: When dust enters the residual current type electrical fire monitoring detector 1, it will be blocked by the filter plate 207, thus preventing the dust from entering the interior of the residual current type electrical fire monitoring detector 1. When it is necessary to clean the filter plate 207, pull the pull handle 215 outward, which can drive the sliding bar 202 to move outward along the sliding rail 201, and then drive the toothed plate 208 to move outward. At the same time, the filter plate 207 will also move outward. When the toothed plate 208 moves outward, it can drive the gear 213 to rotate. After the gear 213 rotates, it can drive the rotating shaft 212 to rotate. When the rotating shaft 212 rotates, it can drive the cleaning roller brush 214 to rotate. When the filter plate 207 contacts the outer part of the cleaning roller brush 214, the cleaning roller brush 214 will squeeze the filter plate 207 outward. At this time, the abutting spring 204 will provide a pulling force to pull the limiting round block 205 towards the direction close to the residual current type electrical fire monitoring detector 1, so that the movable rod 206 is pulled towards the residual current type electrical fire monitoring detector 1. Therefore, the filter plate 207 can be closely attached to the outer part of the cleaning roller brush 214. Similarly, when the filter plate 207 is located at the heat dissipation holes on both sides of the residual current type electrical fire monitoring detector 1, it will also be subjected to the pulling force of the abutting spring 204, so that the filter plate 207 is closely attached to both sides of the residual current type electrical fire monitoring detector 1, preventing dust from entering the gap. When the cleaning roller brush 214 rotates, the cleaning roller brush 214 can clean the filter plate 207; When the filter plate 207 moves outward, it drives the groove plate 305 to move outward. When the groove on the groove plate 305 moves to one side of the knocking rod 304, under the action of the torsion spring 303, it drives the rotating outer sleeve 302 to rotate, and then drives the knocking rod 304 to move towards the groove of the groove plate 305. When the knocking rod 304 moves out of the groove of the groove plate 305, it will drive the knocking rod 304 to rotate, and then compress the torsion spring 303. Therefore, the knocking rod 304 continuously moves in and out of the groove of the groove plate 305, causing the knocking rod 304 to knock on the groove plate 305, and then the vibration generated on the groove plate 305 can be transmitted to the filter plate 207, so that the dust on the filter plate 207 can fall off. Cooperating with the cleaning roller brush 214 can play a role in cleaning the filter plate 207; When installing the residual current type electrical fire monitoring detector 1, first fix the installation base 407 inside a distribution box or a power distribution room and other places by bolts through the holes on the installation base 407. At this time, slide the installation slide plate 401 into the installation groove 408. When the engaging head 406 is about to enter the installation groove 408, turn the round handle 410, which can drive the rotating core 403 to rotate, thereby driving the steel rope to rotate towards the middle, and then pulling the limiting circular plate 405 towards the middle, and then driving the engaging head 406 to move towards the middle. When the engaging head 406 enters the placement groove 402, slide the installation slide plate 401 into the installation groove 408 again and completely slide it into the installation groove 408. When the engaging head 406 moves to the engaging hole 409, release the rotation of the round handle 410. Under the action of the return spring 404, drive the limiting circular plate 405 to move outwards, and then the engaging head 406 can slide into the engaging hole 409 to complete the installation of the residual current type electrical fire monitoring detector 1. When disassembling, rotate the round handle 410 again to drive the steel rope to wind towards the middle, and then the engaging head 406 can move into the placement groove 402. At this time, after sliding the installation slide plate 401 out of the installation groove 408, the residual current type electrical fire monitoring detector 1 can be disassembled from the installation base 407. Therefore, when the installation base 407 is installed inside a distribution box or a power distribution room and other places, there is no need to disassemble the installation base 407 again. Then, when installing the residual current type electrical fire monitoring detector 1 again in the future, there is no need to install it with bolts again.
