Problems solved by technology

However, the filter layer has a limited service life. In order to ensure the effect of use, the filter layer needs to be replaced frequently. At the same time, because there is a lot of dust on the construction site, it is easy to cause dust accumulation outside the filter layer, which further affects the filtering effect. Causes a drop in efficiency and an increase in fan energy consumption

Embodiment 1

[0053] combine Figure 1-3 , a distribution box convenient for safe management, including a housing 1, the distribution box housing is widely used in this field, its structure and principle are well known to those skilled in the art, and will not be described in detail here.

[0054] A partition 11 is arranged inside the housing 1, and the partition 11 divides the space in the housing 1 into an upper power distribution space 12 and a lower ventilation space 13, and the power distribution space 12 is used for installing and setting power distribution Components (not shown in the figure, not described in detail here); the ventilation space 13 is used to install the ventilation component 5 to realize the exchange of air and moisture in the power distribution space.

[0055] Further, the shell 1 is also provided with an upper door 2 and a lower door 3 , the upper door 2 can realize the opening and closing of the power distribution space 12 , and the lower door 3 can realize the op...

Embodiment 2

[0062] On the basis of embodiment 1, in conjunction with description Figure 3-5 , this embodiment further discloses the specific structure of the ventilation assembly 5 .

[0063] Combined with the manual Figure 4-5 , the ventilation assembly 5 includes an upper pipe 58 , a filter pipe 51 , a direct blowing pipe 52 , a three-way regulating valve 53 , an exhaust fan 54 , a filter layer 56 and an air blowing port 55 .

[0064] One end of the upper pipe 58 is connected to the inlet of the three-way regulating valve 53 , and the other end is connected to the exhaust fan 54 .

[0065] One end of the filtering pipeline 51 and the direct blowing pipeline 52 are respectively connected to two outlets of a three-way regulating valve 53 . The other end of the filter pipe 51 is provided with a threaded opening, and the filter layer 56 is detachably connected to the filter pipe 51 through threads. The other end of the straight blowing pipe 52 is provided with an air blowing port 55 , ...

Embodiment 3

[0073] On the basis of embodiment 1-2, in conjunction with description Figure 3-5 In this embodiment, taking two ventilation assemblies 5 installed in the ventilation space 13 as an example, the working principle of the ventilation assemblies is further disclosed.

[0074] A first ventilation assembly and a second ventilation assembly are installed in the ventilation space 13 . During use, the controller collects the temperature and humidity inside and outside the distribution box through the first temperature sensor, the first humidity sensor, the second temperature sensor, and the second humidity sensor respectively.

[0075] When the temperature inside the distribution box is greater than the external temperature, and the internal air humidity is lower than the external humidity. The first ventilation component is used as the exhaust component, and its exhaust fan starts to rotate forward. The three-way regulating valve of the first ventilation component closes the direct...

Abstract

The invention discloses a power distribution box convenient for safety management. The power distribution box is characterized in that a partition plate is arranged in the shell of the power distribution box, the space in the shell is divided into a power distribution space and a ventilation space by the partition plate, the power distribution space is used for installing power distribution components, the ventilation space is used for installing ventilation assemblies, a first temperature sensor, a first humidity sensor and a controller are arranged in the power distribution space and used for detecting the air temperature and humidity in the power distribution box, and a second temperature sensor and a second humidity sensor are arranged outside the shell and used for detecting the air temperature and humidity outside the distribution box. According to the invention, the temperature and humidity in the power distribution box are controlled through the controller so as to improve the safety coefficient of the power distribution box, and alternate maintenance of the two ventilation assemblies is achieved through the arrangement of the at least two ventilation assemblies so as to prolong the service time of the ventilation assemblies.

Description

technical field [0001] The invention relates to the technical field of safety equipment for building engineering construction, in particular to a distribution box which is convenient for safety management. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box. [0003] For distribution boxes used in humid areas, due to the hot and humid environment, high air humidity, and large changes in ambient temperature, the inside of the distribution box is often relatively humid. The ambient temperature is high. When the external ambient temperature drops at night, the temperature of the enclosure of the distribution box decreases. When the hot and humid air in the distribution box encounters the cold enclosure of the distribution box, the water vapor in the air will conden...
