Description

Technical Field

[0001] The present invention provides a rat and insect-proof electricity meter box, belonging to the technical field of electricity meter boxes. Background Art

[0002] The electricity meter box is the basis for the standard installation of the electricity metering device and is currently widely used in the one-meter-per-household renovation project and the electricity meter replacement project. Since the electricity meter box is usually installed in buildings where residents are relatively concentrated, certain insect and rat protection measures need to be taken for the electricity meter box.

[0003] Currently, a patent document with the publication number CN219123768U discloses a distribution box with a rat and insect prevention device, including a distribution box body. A radiator is fixedly installed on one side of the distribution box body, and at least two exhaust fans are arranged inside the radiator. By setting the radiator, an insect-proof baffle, and a mounting handle, this design effectively solves the problem that in actual use, after installing the radiator in the existing distribution box, it often communicates with the external air. Once flying insects and rats enter the inside of the distribution box and move, it is very likely to cause a major electrical fire accident.

[0004] For the distribution box with a rat prevention device disclosed in the above patent document, a heat dissipation device is only arranged on one side of the distribution box, and the heat dissipation fins on the other side of the distribution box cannot intake air, resulting in poor ventilation and heat dissipation inside the distribution box. Moreover, after the insect-proof baffle on the surface of the distribution box adsorbs the insect net, its through holes are prone to blockage and need to be frequently cleaned, which is cumbersome to operate. Summary of the Invention

[0005] In order to overcome the technical problems of poor ventilation and heat dissipation, lack of rat prevention function, and easy blockage of the insect-proof baffle in the existing distribution box, the present invention provides a rat and insect-proof electricity meter box with an improved structure.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a rat and insect-proof electricity meter box, including an electricity meter box body. A partition is fixedly connected to the inner wall of the electricity meter box body. A rat prevention mechanism and an air inlet hole are further arranged on the lower surface of the electricity meter box body, and an insect-proof net assembly is arranged inside the air inlet hole. Exhaust holes are opened on both the left and right sides of the electricity meter box body, a wind guide cover is fixedly connected to the outside of the exhaust holes, and a dust-proof metal net is fixedly connected to the inner wall of the exhaust holes.

[0007] Ventilation holes are opened on the upper surface of the partition, and an air inlet fan is installed at the top of the ventilation holes. Both the air inlet fan and the ventilation holes are arranged directly above the air inlet hole.

[0008] The rat prevention mechanism includes an anti-climbing shell fixedly connected to the lower surface of the electricity meter box body, and a plurality of spiked cone columns are fixedly connected to the inner wall of the anti-climbing shell.

[0009] The insect-proof net assembly includes a movable net shell, which is slidably connected to the inner wall of the air inlet hole. A linkage plate is fixedly connected to the upper surface of the movable net shell, and a number of strip-shaped through holes are formed on the surface of the linkage plate; Rubber connecting bands are fixedly connected to both the left and right sides of the linkage plate, and the sides of the rubber connecting bands away from the linkage plate are fixedly connected to the inner wall of the electricity meter box body.

[0010] Four L-shaped plates are symmetrically distributed on the upper surface of the linkage plate, and movable plates are fixedly connected to the surfaces of the two L-shaped plates on the same side; A limiting rod is fixedly connected between the lower surface of the partition plate and the movable plate. A limiting through hole matching the limiting rod is formed on the surface of the movable plate, and the movable plate is slidably connected to the surface of the limiting rod through the limiting through hole; A return spring is sleeved on the surface of the limiting rod, and the top end of the return spring is fixedly connected to the lower surface of the movable plate; A driving motor for driving the movable plate to move up and down is also fixedly installed on the inner wall of the electricity meter box body. The output end of the driving motor is fixedly connected to a driving rod. A transmission rod is fixedly connected between the front and rear inner walls of the electricity meter box body. Synchronous wheels are fixedly connected to the surfaces of the driving rod and the transmission rod, and a transmission belt is sleeved on the surface of the synchronous wheel. The driving motor drives the transmission rod to rotate through the synchronous wheel and the transmission belt; Driving cams are installed on the surfaces of the driving rod and the transmission rod. The installation positions of the driving cams correspond to the movable plates, and the driving cams are lapped with the upper surfaces of the movable plates.

[0011] The beneficial effects of the present invention compared with the prior art are as follows: The present invention provides a mouse-proof mechanism at the position of the air inlet hole at the bottom of the existing electricity meter box. Specifically, a number of spike cone columns on the inner wall of the anti-climbing shell form a barrier, so that it is easy for mice to slip after climbing into the inner wall of the anti-climbing shell, and the spike cone columns can play an effective blocking role to prevent mice from entering the electricity meter box through the air inlet hole; at the same time, an insect-proof net assembly is provided inside the electricity meter box body. When the outer surface of the movable net shell inside the air inlet hole is blocked by the insect net, the driving motor can be used to drive the driving rod and the transmission rod to rotate, and then drive the two driving cams to rotate simultaneously. The driving cams are used to push the movable plate downward during rotation, and then the movable plate is used to drive the L-shaped plate to move up and down. Under the action of the return spring, the movable net shell vibrates up and down on the inner wall of the air inlet hole, and the insect net adsorbed on the surface of the movable net shell is cleaned by the vibration, realizing the effect of preventing the insect-proof net from being blocked.
