Description

Technical Field

[0001] The utility model relates to the technical field of electric energy metering boxes, in particular to an electric energy metering box with an automatic fire extinguishing function. Background Art

[0002] The electric energy meter box is a new type of electrical equipment, which is a product specially used to calculate electric energy. It is very common in daily life. The electric energy meter box is mainly composed of a box body, a box door, an electric meter, a circuit breaker and other equipment. At present, the electric energy meter boxes of many residential areas, apartments and office buildings are usually installed inside the power well. Fire hydrants are generally equipped next to the power well. Once a fire occurs in the electric energy meter box due to a short circuit or other fault, fire prevention measures can be taken immediately. However, in rural areas, due to the relatively scattered residence of people, the electric energy meter box does not have a centralized and accurate installation location, so it is usually not equipped with fire-fighting facilities. Once a fire occurs in the electric energy meter box due to a short circuit or other fault, it is easy to cause a large safety accident and economic losses;

[0003] In the prior art, for example, announcement number CN219180982U proposes an electric energy meter box. This technical solution discloses an electric energy meter box, which belongs to the technical field of electric energy meter boxes, and includes a main box body and a box door. A hinge is installed on one side of the front end of the main box body, and the box door is hinged to the front end of the main box body through the hinge. An electric meter is installed inside the main box body, and a circuit breaker is installed below the electric meter. A protective cover is installed above the main box body, and a fire extinguishing assembly is fixed to the bottom end of the protective cover. The fire extinguishing assembly includes a fire box, a fire extinguishing agent, a sealing film and a support frame, and the fire box is fixedly connected to the bottom end of the protective cover. The utility model forms a simple fire-fighting facility by filling a fire extinguishing agent inside the fire box. When an open fire occurs inside the electric energy meter box due to a fault, the simple fire-fighting facility will automatically release the fire extinguishing agent to extinguish the open fire and prevent the spread of the fire, thereby avoiding major safety accidents and economic losses. It is worthy of promotion and use in rural areas.

[0004] However, when an open fire occurs inside the electric energy meter box of the prior art solution during use, the sealing film melts due to heat, and the fire extinguishing agent filled in the fire extinguishing box is released under the action of gravity, which can extinguish the open fire inside the electric energy meter box. However, it is difficult to restore the sealing film at the bottom of the fire extinguishing box after it melts, so that the fire extinguishing box cannot play the role of extinguishing the fire again, so the only option is to replace the fire extinguishing box with a new one, which causes certain waste;

[0005] In order to solve the above problems, the present application proposes an electric energy metering box with automatic fire extinguishing function. Utility Model Content

[0006] The utility model is intended to provide an electric energy metering box with an automatic fire extinguishing function, which is mainly used to solve the problem that the sealing film at the bottom of the fire extinguishing box on the existing electric energy metering box is difficult to recover after melting, resulting in the fire extinguishing box being unable to play a role in fire extinguishing again.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] An electric energy metering box with automatic fire extinguishing function comprises a box body, an electric meter, a protective cover and a fire fighting box fixedly connected to the bottom of the protective cover, a slide plate is slidably connected to the bottom of the fire fighting box, guide blocks are fixedly connected to both sides of the slide plate, guide grooves matching the guide blocks are provided on both sides of the inner wall of the fire fighting box, a through groove matching the slide plate is provided on one side of the box body, a screw rod is rotatably connected between the two sides of the inner wall of the box, a moving plate passes through the outer wall of the screw rod, the moving plate and the screw rod are threadedly connected, a push plate matching the slide plate is fixedly connected to the top of the moving plate, one side of the push plate is set against the slide plate, a driving assembly is fixedly connected to one side of the inner wall of the box, and one end of the screw rod is fixedly connected to the driving assembly.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When an open fire occurs inside the electric energy metering box during use, the drive assembly can drive the screw to rotate, thereby driving the moving plate to move inside the box. While the moving plate moves, the push plate can push the slide plate to slide on the bottom of the fire box, thereby opening it and allowing the dry powder fire extinguishing agent inside the fire box to be released under the action of gravity, and extinguish the open fire inside the box, thereby playing a role of automatic fire extinguishing. After the open fire inside the box is extinguished, the protective cover, fire box and slide plate can be taken out from the inside of the box. After adding fire extinguishing agent to the inside of the fire box, it can play the role of fire extinguishing again.

[0011] 2. Beneficial effect: When an open fire appears inside the electric energy metering box, the slide plate at the bottom of the fire extinguishing box can be pushed open through the operation of the driving component, so that the fire extinguishing agent inside the fire extinguishing box is released under the action of gravity and the open fire inside the box is extinguished, thereby playing the role of automatic fire extinguishing. After the protective cover, the fire extinguishing box and the slide plate are taken out from the inside of the box and the fire extinguishing agent is added to the inside of the fire extinguishing box, the fire extinguishing box can play the role of fire extinguishing again, so that the fire extinguishing box can be recycled, thereby effectively reducing waste.

[0012] Preferably, the drive assembly includes a mounting plate fixedly connected to one side of the inner wall of the box, a motor fixedly connected to the top of the mounting plate, an output end of the motor fixedly connected to a first bevel gear, one side of the first bevel gear meshingly connected to the second bevel gear, one end of the screw rod passes through the second bevel gear and is fixedly connected to the second bevel gear, a temperature sensor is fixedly connected to one side of the inner wall of the box close to the motor, the temperature sensor is electrically connected to the motor, when an open flame appears inside the electric energy metering box, the temperature sensor detects an increase in the temperature inside the box, and will send an electrical signal to the motor, thereby controlling the motor to start, the operation of the motor can drive the first bevel gear to rotate, and the rotation of the first bevel gear can drive the second bevel gear to rotate synchronously, because the screw rod is fixedly connected to the second bevel gear, the rotation of the second bevel gear can drive the screw rod to rotate, and the rotation of the screw rod can push the slide plate and open it, so that the dry powder fire extinguishing agent inside the fire box is released under the action of gravity, and the open fire inside the box is extinguished, thereby achieving the effect of automatic fire extinguishing.

[0013] Preferably, multiple ventilation holes are provided on both sides of the box, and the inner walls of the ventilation holes are fixedly connected with filter nets. A certain amount of heat will be generated during the operation of the electricity meter inside the box. The ventilation holes on both sides of the box can realize air flow inside the box, thereby achieving a better heat dissipation effect on the electricity meter. The filter nets arranged on the inner walls of the ventilation holes can prevent external dust from entering the box and affecting the normal operation of the electricity meter, thereby effectively extending the service life of the electricity meter.

[0014] Preferably, one end of the screw rod passes through the box and is rotatably connected to the box, and one end of the screw rod extending out of the box is fixedly connected to a spur gear, one side of the spur gear is meshingly connected to a toothed plate, and the lower end of the toothed plate is fixedly connected to a baffle, and the baffle and the toothed plate are both slidably connected to the side wall of the box, and the baffle is matched with the ventilation hole. When an open flame appears inside the box, the drive assembly will drive the screw rod to rotate, and the rotation of the screw rod can also drive the spur gear to rotate. When the spur gear rotates, the baffle can be driven downward by the toothed plate, thereby having a better blocking effect on the ventilation holes on one side of the box, so that the airflow inside the box cannot continue to flow, thereby effectively reducing the fire inside the box.

[0015] Preferably, a magnet that attracts the skateboard is fixedly connected to one side of the push plate. Through the magnet arranged on one side of the push plate, when the push plate and the skateboard are against each other, the magnet will be attracted to the skateboard. The advantage of such an arrangement is that when the driving assembly drives the screw rod to rotate in the opposite direction, the push plate can drive the skateboard to move synchronously and reset, thereby making the device more automated.

[0016] Preferably, a symmetrical T-shaped slider is fixedly connected to one side of the baffle, and a T-shaped slot matching the T-shaped slider is opened on one side of the box body. When the baffle slides on one side of the box body, the T-shaped slider arranged on one side of the baffle and the T-shaped slot opened on one side of the box body can play a better limiting and guiding role for the baffle, thereby making the baffle more stable when sliding on one side of the box body.

[0017] Preferably, a T-shaped slider is rotatably connected to a side away from the baffle plate, and the balls are equidistantly distributed in a linear array on one side of the T-shaped slider. When the baffle plate slides on one side of the box body, the T-shaped slider will slide inside the T-shaped groove. The multiple balls arranged on one side of the T-shaped slider can effectively reduce the friction between the T-shaped slider and the inner wall of the T-shaped groove, thereby making the baffle plate slide more smoothly on one side of the box body.

One side of the push plate 10 is fixedly connected with a magnet 23 attracted to the slide plate 5. One side of the inner wall of the box body 1 is fixedly connected with a driving component. One end of the screw rod 8 is fixedly connected to the driving component. The operation of the driving component can drive the screw rod 8 to rotate, thereby driving the movable plate 9 to move inside the box body 1. While the movable plate 9 moves, the slide plate 5 can be pushed to slide on the bottom of the fire box 4 through the push plate 10, thereby opening it. The fire extinguishing agent inside the fire box 4 can extinguish the open fire inside the box body 1.

[0027] like Figure 3 and Figure 6As shown, the drive assembly includes a mounting plate 11 fixedly connected to one side of the inner wall of the box body 1, a motor 12 fixedly connected to the top of the mounting plate 11, a first bevel gear 13 fixedly connected to the output end of the motor 12, a second bevel gear 14 meshingly connected to one side of the first bevel gear 13, one end of the screw rod 8 passes through the second bevel gear 14 and is fixedly connected to the second bevel gear 14, and a temperature sensor 24 is fixedly connected to one side of the inner wall of the box body 1 near the motor 12. When an open flame appears inside the electric energy metering box, the temperature sensor 24 will detect that the temperature inside the box body 1 has risen, and a fire will be generated. An electrical signal is output to the motor 12, thereby controlling the motor 12 to start. The operation of the motor 12 can drive the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 can drive the second bevel gear 14 to rotate synchronously. Since the screw rod 8 is fixedly connected to the second bevel gear 14, the rotation of the second bevel gear 14 can drive the screw rod 8 to rotate. When the screw rod 8 rotates, the slide plate 5 can be pushed and opened by the push plate 10, so that the dry powder fire extinguishing agent inside the fire box 4 is released under the action of gravity, and the open fire inside the box body 1 is extinguished, which plays a role of automatic fire extinguishing.

[0028] like Figure 2 As shown, multiple ventilation holes 15 are provided on both sides of the box body 1, which can realize air flow inside the box body 1, thereby having a good heat dissipation effect on the electricity meter 2, and the inner walls of the ventilation holes 15 are fixedly connected with filter screens to prevent external dust from entering the box body 1 and affecting the normal operation of the electricity meter 2, thereby effectively extending the service life of the electricity meter 2, one end of the screw rod 8 passes through the box body 1 and is rotatably connected between the box body 1, and one end of the screw rod 8 extending out of the box body 1 is fixedly connected with a spur gear 16, one side of the spur gear 16 is meshedly connected with a tooth plate 17, and the lower end of the tooth plate 17 is fixedly connected with a baffle 18, and the baffle 18 and the tooth plate 17 are both slidably connected to the side wall of the box body 1, and one side of the baffle 18 is fixedly connected with a symmetrical T-shaped slider 19, and one side of the box body 1 is provided with a T-shaped slide groove 20 matching the T-shaped slider 19, and the baffle 18 is matched with the ventilation hole 15. When an open fire appears inside the box body 1, the driving assembly will drive the screw rod 8 to rotate. When the screw rod 8 rotates, it can drive the spur gear 16 to rotate. When the spur gear 16 rotates, it can drive the baffle 18 to move downward through the tooth plate 17, thereby effectively blocking the ventilation hole 15 on one side of the box body 1, so that the airflow inside the box body 1 cannot continue to flow, thereby effectively slowing down the fire inside the box body 1. The T-shaped slider 19 is rotatably connected to the side away from the baffle 18, and the balls 21 are equidistantly distributed on one side of the T-shaped slider 19 in a linear array. When the baffle 18 slides on one side of the box body 1, the T-shaped slider 19 will slide inside the T-shaped groove 20. The multiple balls 21 arranged on one side of the T-shaped slider 19 can effectively reduce the friction between the T-shaped slider 19 and the inner wall of the T-shaped groove 20, so that the baffle 18 can slide more smoothly on one side of the box body 1.

[0029] From the above, it can be seen that the specific implementation of the utility model is as follows:

[0030] When an open flame appears inside the electric energy metering box during use, the temperature sensor 24 detects that the temperature inside the box body 1 rises, and sends an electrical signal to the motor 12, thereby controlling the motor 12 to start. The operation of the motor 12 can drive the first bevel gear 13 to rotate, and the rotation of the first bevel gear 13 can drive the second bevel gear 14 to rotate synchronously. Since the screw rod 8 is fixedly connected to the second bevel gear 14, the rotation of the second bevel gear 14 can drive the screw rod 8 to rotate, and the rotation of the screw rod 8 can drive the movable plate 9 to move inside the box body 1. When the movable plate 9 moves, the sliding plate can be pushed by the push plate 10 5 slides on the bottom of the fire box 4, thereby opening it and releasing the dry powder fire extinguishing agent in the fire box 4 under the action of gravity, and extinguishing the open fire in the box body 1, thereby playing the role of automatic fire extinguishing, and the screw rod 8 can drive the spur gear 16 to rotate while rotating, and the spur gear 16 can drive the baffle 18 to move downward through the tooth plate 17 while rotating, thereby playing a better blocking role on the ventilation hole 15 on one side of the box body 1, so that the airflow in the box body 1 can not continue to flow, which can effectively reduce the fire in the box body 1, and thus make the device have a better fire extinguishing effect on the electric energy metering box.
