Existing fire-fighting facilities in high-rise residential buildings need to be uniformly installed with devices for controlling sprinklers and alarm systems.
[0003] Currently, when using fire-fighting monitoring equipment, when a fire occurs inside the corridor, local alarms and local sprinkler systems will work.

[0006] A damping member is arranged between the first copper block and the second copper block. A docking member is arranged on the inner bottom surface of the main body of the installation box near the other side edge. The top of the main body of the installation box is provided with a top cover. A rubber pad is fixed to the bottom of the top cover. The outer surface of the rubber pad is mutually attached to the inner wall of the main body of the installation box. Docking columns are fixed to both sides of the main body of the installation box. One ends of the two docking columns are respectively fixed to one side of the first copper block and the second copper block.
[0007] Preferably, the induction adjustment device includes an adjustment pipe, which penetrates through the water supply pipe and extends to one side inner wall of the installation box body. An adjustment rod is slidably connected inside the adjustment pipe. A through hole is opened on one side of the adjustment rod, which faces the inside of the water supply pipe. One end of the adjustment rod extends to the outside of the adjustment pipe.
[0008] Preferably, guide grooves are opened on both inner walls of the adjustment pipe. Guide blocks are fixed on the outer surfaces of both sides of the adjustment rod. The two guide blocks are respectively slidably connected inside the guide grooves. A second spring is fixed at one end of the adjustment rod, and one end of the second spring is fixed on one side inner wall of the installation box body.
[0009] Preferably, the sensing element includes a bimetallic strip. A bayonet is opened on the top of the first copper block. A clamping plate is fixed on one side of the bimetallic strip, and the clamping plate is clamped inside the bayonet.
[0010] Preferably, a limiting plate is fixed on the other side of the bimetallic strip. A push plate is fixed on one side of the limiting plate. An arc-shaped plate is fixed on the top of the bimetallic strip.
[0011] Preferably, the damping element includes two clamping heads, which are respectively clamped at one ends of the first copper block and the second copper block. A plurality of damping rods are fixed between the corresponding sides of the two clamping heads. A damping ring is slidably connected between the outer surfaces of the plurality of damping rods.
[0012] Preferably, one side of the limiting plate is clamped on one side of the damping ring, and one end of the adjustment rod extends to one side of the arc-shaped plate.
[0013] Preferably, the docking element includes a guide rod, which is fixed on one side inner wall of the installation box body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. During actual use, the sensing element is snapped onto the first copper block and fixed in place by the damping limit of the damping element. Then, the docking post is docked with an external wire. When the current is too large, the sensing element will deform. When the force generated by the deformation is greater than the damping force of the damping element, the telescopic deformation of the sensing element drives the docking part and the sensing adjustment device to move, thus spraying water while cutting off the circuit to prevent a large load pressure from being generated due to continuous power supply;
[0017] 2. When the sensing element is working, mainly due to the different magnitudes of the current flowing through the bimetal sheet, the bimetal sheet is made by superimposing two different metals. When the currents are different, the thermal deformations generated by the two metals are also different, so it will generate a bending deformation. Under the action of the bending deformation, the bimetal sheet can drive the push plate to push the contact block to one side, separating the contact block from the second copper block, so that the current on the second copper block cannot be transmitted to the bimetal sheet through the contact block, cutting off the circuit. And when the push plate pushes the contact block, one side of the push plate also contacts the oil bag, which can squeeze the oil bag to extrude the insulating oil liquid inside the oil bag and coat it on the contact surface between the contact block and the second copper block to prevent an electric arc from being generated when the contact block and the second copper block are separated from each other;
[0018] 3. Under the action of the bending deformation, the concave surface of the bimetal sheet moves towards one end of the adjusting rod, which can push the adjusting rod into the interior of the adjusting tube, making the through hole communicate with the interior of the water supply pipe, so that the water flow inside the water supply pipe can flow into the interior of the side pipe.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0027] Please refer to Figures 1-6 , the present invention provides a technical solution: a fire-fighting equipment overload monitoring system, including an installation box body 1, a water supply pipe 3 is arranged on one side of the installation box body 1, one end of the water supply pipe 3 extends to the outside of the installation box body 1, one end of the water supply pipe 3 is communicated with a side pipe 4, a plurality of branch pipes 5 are equidistantly arranged on the outer surface of the side pipe 4, an induction adjustment device is arranged on the outer surface of the water supply pipe 3, a first copper block 12 is fixed on the inner bottom surface of the installation box body 1 near one side edge, an induction element is arranged on the first copper block 12, a second copper block 16 is fixed on the inner bottom surface of the installation box body 1 near the other side edge, a damping element is arranged between the first copper block 12 and the second copper block 16, a docking element is arranged on the inner bottom surface of the installation box body 1 near the other side edge, a top cover 6 is arranged on the top of the installation box body 1, a rubber pad 14 is fixed on the bottom of the top cover 6, the outer surface of the rubber pad 14 is mutually attached to the inner wall of the installation box body 1, docking columns 2 are fixed on both sides of the installation box body 1, and one ends of the two docking columns 2 are respectively fixed on one side of the first copper block 12 and the second copper block 16.
[0028] The achieved effect is that in actual use, the induction element is clamped on the first copper block 12, and the induction element is fixed under the damping limit of the damping element. Then, the docking column 2 is docked with the external wire. When the current is too large, the induction element will deform. When the force generated by the deformation is greater than the damping force of the damping element, the induction element expands and contracts to drive the docking element and the induction adjustment device to move, so as to cut off the circuit while spraying water, preventing a large load pressure from being generated by continuous power supply.
[0029] Such as Figures 2-6As shown in the figure, the induction adjustment device includes an adjustment pipe 13. The adjustment pipe 13 penetrates through the water supply pipe 3 and extends to the inner wall on one side of the installation box body 1. A sliding connection is provided inside the adjustment pipe 13 with an adjustment rod 31. A through hole 27 is provided on one side of the adjustment rod 31, and the through hole 27 faces the inside of the water supply pipe 3. One end of the adjustment rod 31 extends to the outside of the adjustment pipe 13. Guide grooves 29 are provided on the inner walls on both sides of the adjustment pipe 13, and guide blocks 30 are fixed on the outer surfaces on both sides of the adjustment rod 31. The two guide blocks 30 are respectively slidably connected inside the guide grooves 29. A second spring 28 is fixed at one end of the adjustment rod 31, and one end of the second spring 28 is fixed on the inner wall on one side of the installation box body 1.
[0030] The achieved effect is that when the induction component works, under the action of bending deformation, the concave surface of the bimetallic sheet 7 moves towards one end of the adjustment rod 31, and the adjustment rod 31 can be pushed into the adjustment pipe 13, so that the through hole 27 is in communication with the inside of the water supply pipe 3, enabling the water flow inside the water supply pipe 3 to flow into the side pipe 4. And a second spring 28 is fixed between one end of the adjustment rod 31 and the inner wall on one side of the installation box body 1, so that it can automatically reset. At the same time, during the sliding process of the adjustment rod 31, through the mutual engagement of the guide block 30 and the guide groove 29, the adjustment pipe 13 slides more smoothly and the rotation phenomenon of the adjustment pipe 13 can be prevented.
[0031] As Figures 2-6 shown in the figure, the induction component includes a bimetallic sheet 7. A bayonet 15 is provided at the top of the first copper block 12. A clamping plate 11 is fixed on one side of the bimetallic sheet 7, and the clamping plate 11 is clamped inside the bayonet 15. A limiting plate 9 is fixed on the other side of the bimetallic sheet 7, a push plate 8 is fixed on one side of the limiting plate 9, and an arc-shaped piece 10 is fixed on the top of the bimetallic sheet 7.
[0032] The achieved effect is that when the induction component works, mainly due to the different magnitudes of the current flowing through the bimetallic sheet 7. The bimetallic sheet 7 is made of two different metals stacked together. When the currents are different, the thermal deformations of the two metals are also different, so bending deformation will occur. Through the push plate 8, the contact block 22 can be pushed to move, and through the arc-shaped piece 10, the adjustment rod 31 can be pushed to move.
[0033] As Figures 2-6 shown in the figure, the damping component includes two clamping heads 24. The two clamping heads 24 are respectively clamped at one ends of the first copper block 12 and the second copper block 16. A plurality of damping rods 25 are fixed between the corresponding sides of the two clamping heads 24. A damping ring 26 is slidably connected between the outer surfaces of the plurality of damping rods 25. One side of the limiting plate 9 is clamped on one side of the damping ring 26, and one end of the adjustment rod 31 extends to one side of the arc-shaped piece 10.
[0034] The achieved effect is that the damping ring 26 is arranged between the outer surfaces of a plurality of damping rods 25, so that a damping force is generated between the damping ring 26 and the plurality of damping rods 25, thereby clamping and restricting the bimetal sheet 7. When the bimetal sheet 7 does not produce a large elastic deformation, it is impossible to push the damping ring 26 to move on the outer surface of the damping rod 25.
[0035] As Figures 2-6 shown, the docking part includes a guide rod 17. The guide rod 17 is fixed on the inner wall of one side of the installation box body 1. A movable plate 18 is slidably connected to the outer surface of the guide rod 17. A limiting ring 20 is fixed at one end of the guide rod 17. A first spring 19 is fixed on one side of the movable plate 18. One end of the first spring 19 is fixed on the inner wall of one side of the installation box body 1. A connecting plate 21 is fixed on one side of the movable plate 18. A contact block 22 is fixed on one side of the connecting plate 21. One side of the contact block 22 is in mutual contact with one side of the second copper block 16. An oil bag 23 is arranged on the outer surface of the contact block 22. One side of the push plate 8 extends to the outer surface of the oil bag 23.
[0036] The achieved effect is that under the action of bending deformation, the bimetal sheet 7 can drive the push plate 8 to push the contact block 22 to one side, so that the contact block 22 is separated from the second copper block 16, so that the current on the second copper block 16 cannot be transmitted to the bimetal sheet 7 through the contact block 22, cutting off the circuit. And when the push plate 8 pushes the contact block 22, one side of the push plate 8 also contacts the oil bag 23, and the oil bag 23 can be extruded to squeeze out the insulating oil liquid inside the oil bag 23 and coat it on the contact surface between the contact block 22 and the second copper block 16 to prevent arcs from being generated when the contact block 22 and the second copper block 16 are separated from each other. And a first spring 19 is fixed between one side of the movable plate 18 and the inner wall of one side of the installation box body 1 to facilitate the reset of the contact block 22.
[0037] Usage method and working principle of this device: During actual use, first connect the external wire to the two docking posts 2, so that the current flows through one of the docking posts 2 to the first copper block 12, then from the first copper block 12 to the bimetallic strip 7, from the bimetallic strip 7 to the push plate 8, from the push plate 8 to the contact block 22, from the contact block 22 to the second copper block 16, and finally flows out from the other docking post 2. Snap the limit plate 9 on the sensing part onto the first copper block 12, and fix the sensing part under the damping limit of the damping part. Then dock the docking post 2 with the external wire. When the current is too large, the sensing part will deform. When the force generated by the deformation is greater than the damping force of the damping part, the telescopic deformation of the sensing part drives the docking part and the sensing adjustment device to move, so as to cut off the circuit while spraying water, preventing a large load pressure from being generated due to continuous power supply. When the sensing part is working, mainly due to the different magnitudes of the current flowing through the bimetallic strip 7. The bimetallic strip 7 is made by superimposing two different metals. When the currents are different, the thermal deformations generated by the two metals are also different, so it will generate a bending deformation. Under the action of the bending deformation, the bimetallic strip 7 can drive the push plate 8 to push the contact block 22 to one side, so that the contact block 22 is separated from the second copper block 16, so that the current on the second copper block 16 cannot be transmitted to the bimetallic strip 7 through the contact block 22, cutting off the circuit. And when the push plate 8 pushes the contact block 22, one side of the push plate 8 also contacts the oil bag 23, which can squeeze the oil bag 23 to squeeze out the insulating oil liquid inside the oil bag 23 and coat it on the contact surface between the contact block 22 and the second copper block 16, preventing an electric arc from being generated when the contact block 22 is separated from the second copper block 16. Under the action of the bending deformation, the concave surface of the bimetallic strip 7 moves towards one end of the adjusting rod 31, which can push the adjusting rod 31 into the interior of the adjusting tube 13, so that the through hole 27 is communicated with the interior of the water supply pipe 3, so that the water flow inside the water supply pipe 3 can flow into the interior of the side pipe 4.
[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
