It is widely used, stable and reliable in operation, high in space utilization, small in footprint and environmentally friendly.
[0003] When in use, the existing power box usually only has the heat dissipation equipment on the side for heat dissipation. After the power box has been running for a long time, the heat dissipation efficiency is not enough to reduce the surface temperature of the electrical components in the power box, which can easily cause the temperature in the power box to rise, which has an adverse effect on the operation of the power box.

The rising airflow is discharged from the through holes. The rising airflow can also blow some floating dust on the surface of the electrical components out from the mesh holes of the grid plate, thereby reducing dust accumulation and facilitating heat dissipation of the electrical components.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an engineering power box, comprising a box body, two electric push rods are installed inside the box body, the piston rod ends of the two electric push rods pass through the top of the box body and are installed with an upper cover, the box body is provided with a through hole, the bottom of the upper cover is fixedly connected to a plastic plug, the plastic plug is inserted into the inside of the through hole, a bottom fan is installed at the bottom of the box body, a control mechanism for controlling the electric push rods and the bottom fan is installed inside the box body, a slot is provided inside the box body, the bottom of the upper cover is fixedly connected to a grid plate, and the grid plate is inserted into the inside of the slot.
[0007] Preferably, four side fans are installed inside the box body, and four ventilation windows are opened outside the box body, and the air outlets of the side fans are connected to the ventilation windows.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model pushes the upper cover upwards, thereby pulling out the plastic plug from the through hole, driving the mesh plate to rise, and then starting the bottom fan to create an upward airflow at the bottom of the box body. The airflow takes away the surface temperature of the electrical components, thereby cooling the electrical components. The rising airflow is discharged from the through hole.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 5 The embodiment of the utility model provides an engineering power box, comprising: a box body 1, two electric push rods 8 are installed inside the box body 1, and the piston rod ends of the two electric push rods 8 both pass through the top of the box body 1 and are installed with an upper cover 2.
[0022] Among them, a through hole 16 is opened on the box body 1, a plastic plug 13 is fixedly connected to the bottom of the upper cover 2, and the plastic plug 13 is inserted into the inside of the through hole 16, a bottom fan 12 is installed at the bottom of the box body 1, and a control mechanism for controlling the electric push rod 8 and the bottom fan 12 is installed inside the box body 1, a slot 14 is opened inside the box body 1, a grid plate 15 is fixedly connected to the bottom of the upper cover 2, and the grid plate 15 is inserted into the inside of the slot 14, four side fans 11 are installed inside the box body 1, and four ventilation windows 6 are opened outside the box body 1, and the air outlet of the side fan 11 is connected to the ventilation window 6. The control mechanism includes a temperature sensor 9, which is installed inside the box body 1, and a controller 10 is installed on the inner top of the box body 1. The controller 10 is connected to the temperature sensor 9 by signal, and the electric control end of the controller 10 is electrically connected to the electric control input end of the electric push rod 8, the side fan 11 and the bottom fan 12.
[0023] When in use, the side fan 11 discharges the temperature generated by the electrical components in the box body 1 through the ventilation window 6. When the temperature in the box body 1 exceeds 40°C, the temperature sensor 9 of the control mechanism transmits the temperature information to the controller 10, and the controller 10 starts the electric push rod 8 to push the upper cover 2 upward, thereby pulling the plastic plug 13 out of the through hole 16 and driving the grid plate 15 to rise, and then starts the bottom fan 12 to create an upward airflow at the bottom of the box body 1. The airflow takes away the surface temperature of the electrical components and cools the electrical components. The rising airflow is discharged from the through hole 16. When the temperature sensor 9 detects that the temperature in the box body 1 is lower than 35°C, it stops starting the bottom fan 12 and retracts the piston rod of the electric push rod 8 back to the upper cover 2.
[0024] At the same time, when the mesh plate 15 rises, airflow is discharged from the filter holes of the mesh plate 15 to dissipate heat, and when the upper cover 2 is retracted, the mesh plate 15 is inserted into the slot 14 .
[0025] In order to reduce the vibration of the box body 1 when installing the utility model, a plurality of feet 5 are installed at the bottom of the box body 1. In order to facilitate the movement of the position of the utility model for installation, two lifting ears 7 are installed on the outside of the box body 1.
[0026] In order to facilitate observation of the operating conditions of the electrical components in the box body 1 , a box door 4 is hingedly connected to the outside of the box body 1 , and a tempered glass 3 is embedded on the box door 4 .
[0027] According to the above technical solution, the working steps of this solution are summarized and sorted out: when using the utility model, the side fan 11 discharges the temperature generated by the electrical components in the box body 1 through the ventilation window 6. When the temperature in the box body 1 exceeds 40°C, the temperature sensor 9 of the control mechanism transmits the temperature information to the controller 10, and the controller 10 starts the electric push rod 8 to push the upper cover 2 upward, thereby pulling the plastic plug 13 out of the through hole 16, and driving the mesh plate 15 to rise, and then starts the bottom fan 12 to create an upward airflow at the bottom of the box body 1. The airflow takes away the surface temperature of the electrical components and cools the electrical components. The rising airflow is discharged from the through hole 16. When the temperature sensor 9 detects that the temperature in the box body 1 is lower than 35°C, the bottom fan 12 is stopped, and the piston rod of the electric push rod 8 is retracted and brought back to the upper cover 2. When the mesh plate 15 rises, the airflow is discharged from the mesh holes of the mesh plate 15 to dissipate heat. When the upper cover 2 is retracted, the mesh plate 15 is inserted into the slot 14.
