Problems solved by technology

[0003] Since there are many rats in spring and summer, especially in areas such as garbage dumps, the activity of mice is more frequent, so that the power box installed near the garbage dump is likely to have mice enter the interior through the heat dissipation vents that communicate with the outside world, resulting in damage to the inside of the power box. The power supply line was bitten off by a mouse and there was a damaged short circuit

Embodiment 1

[0029] For example figure 1 -example Image 6 Shown:

[0030] The invention provides a power box for municipal engineering, its structure includes an alarm 1, a box door 2, a control panel 3, a radiator 4, and a power box 5, the alarm 1 is embedded and connected to the power box 5, and the box The door 2 is hingedly connected to the power box 5 , the back surface of the control panel 3 is attached to the surface of the box door 2 , and the radiator 4 is welded to the bottom of the power box 5 .

[0031] Wherein, the heat sink 4 includes a shell 41, a heat dissipation port 42, a fixed block 43, a rebound ring 44, an opening and closing plate 45, an expelling mechanism 46, and a ventilating plate 47, and the heat dissipation port 42 and the shell 41 are an integral structure, so The fixed block 43 is provided with four, and the two on the right end are connected with the inner wall of the casing 41, and the two on the left end are embedded in the right side of the air-permeabl...

Embodiment 2

[0039] For example Figure 7 -example Figure 9 Shown:

[0040] Wherein, the expelling mechanism 46 includes a housing 461, an expelling vane 462, a movable shaft 463, and an outlet 464. The expelling vane 462 is embedded with the movable shaft 463, and the movable shaft 463 is engaged with the bottom of the inner wall of the housing 461. Combined, the outlet 464 and the housing 461 are an integrated structure, and the expelling blades 462 are provided with eight, and are distributed in a circle on the movable shaft 463, and the rats that fall between the expelling blades 462 are dispelled when running. Drive blade 462 thrust, can make it rotate, until mouse is expelled from outlet 464.

[0041] Wherein, the expulsion blade 462 includes a telescopic plate c1, a blocking piece c2, and a cover plate c3. The telescopic plate c1 is matched with the inner wall of the cover plate c3. There are two blocking pieces c2, and one is embedded in the telescopic The outer surface of the ...

Abstract

The invention discloses a power box for municipal engineering, the structure of which comprises an alarm, a box door, a control panel, a radiator, and a power box. The back side fits the surface of the box door, and the radiator is welded to the bottom of the power box. Since mice can easily enter the inside of the power box through the cooling hole on the radiator, this situation can be effectively prevented by the cooperation of the opening and closing plate and the repelling mechanism. , to avoid the phenomenon that the mice enter the power box through the heat dissipation port, causing the circuit inside the power box to be bitten by the mouse. Unnecessary pollution will be caused to the interior of the repelling mechanism, and such problems can be effectively avoided by the cooperation of the repelling blades and the movable shaft.

Description

technical field [0001] The invention relates to the field of electric boxes, in particular to an electric box for municipal engineering. Background technique [0002] The power box is mainly a device for distributing electric energy. It is a control center for rationally distributing electric energy to power supply lines, and it can intuitively monitor the use status of power supply and testing circuits. It is a common device in outdoor public places. Based on the above description, the inventor It is found that the existing electric box for municipal engineering mainly has the following deficiencies, for example: [0003] Because there are more rats in spring and summer, especially in areas such as garbage dumps, the activity of mice is more frequent, so that the power boxes installed near the garbage dumps are likely to have mice enter the interior through the heat dissipation vents that communicate with the outside world, resulting in damage to the inside of the power box...
