According to actual use requirements, the protection requirements and ventilation requirements for prefabricated box-type substations and prefabricated cabin-type distribution equipment are relatively high. At present, ventilation and heat dissipation are mostly achieved by installing louvers on prefabricated box-type substations and prefabricated cabin-type distribution equipment.

[0003] In rainy or foggy weather, the fixedly installed louvers keep the ventilation openings always open, and cannot completely block the rain and fog from entering the equipment, and the humid environment may damage the internal components of the box-type substation; in order to effectively block the rain, fog and fine sand from entering the equipment, the density of the louvers is large and the ventilation channels are small, then the effective heat dissipation area cannot be guaranteed, affecting the heat dissipation effect, and the high-temperature environment may also damage the internal components of the box-type substation. Summary of the Utility Model

[0004] In view of the above problems in the prior art, the purpose of the utility model is to provide a door body structure with a ventilation mechanism and good protection effect, which adjusts the structure of the switch component through a driving member, thereby adjusting the position of the louvers to adjust the heat dissipation area, and realizing the conversion between good heat dissipation effect and good protection effect under different conditions, and discharging the condensed water through a condensate collecting groove and a drain pipe to ensure the dryness of the internal environment of the equipment.

[0005] A door body structure with a ventilation mechanism and good protection effect includes a door frame and a door panel. A ventilation mechanism is arranged on the door panel. The ventilation mechanism includes a switch component installed in a ventilation groove on the door panel. The switch component includes a connecting rod connected to a driving member. An array of louvers is connected to the connecting rod through a crank arm. The driving member drives the connecting rod to move up and down to drive the louvers to act. When the ventilation mechanism is in a ventilation state, a ventilation channel is formed between adjacent louvers. When the ventilation mechanism is in a closed state, adjacent louvers are in contact with each other to form a baffle structure to block the ventilation groove. A condensate collecting groove is installed at the bottom of the ventilation groove. The condensate collecting groove is in a funnel-shaped structure. The bottom of the condensate collecting groove is connected to a drain pipe, and the other end of the drain pipe extends to the outside of the door panel.

[0009] Preferably, a filter screen is installed in the ventilation slot on the door panel.

[0010] The beneficial effects of the present utility model are as follows: For the door body structure with a ventilation mechanism and good protection effect, the structure of the switch assembly is adjusted by the driving member, so as to adjust the position of the louvers to adjust the heat dissipation area.

Detailed Description of the Embodiments

[0016] Embodiment 1

[0017] As Figure 1 、 Figure 3As shown in the figure, a door structure with a good protection effect and a ventilation mechanism includes a door frame 1 and a door panel 2. Among them, a ventilation mechanism 13 is configured on the door panel 2, and the ventilation mechanism 13 includes a switch assembly installed in a ventilation slot on the door panel 2. In order to prevent dust and flying insects from entering the interior of the device, a filter screen 8 is installed in the ventilation slot on the door panel 2.

[0018] As Figure 3 shown, the switch assembly includes a connecting rod 7 connected to a driving member 11, and a plurality of louvers 5 distributed in an array are connected to the connecting rod 7 through a crank arm 6; the driving member 11 drives the connecting rod 7 to move up and down to drive the louvers 5 to act. As Figure 3 shown on the left side, when the device needs to improve the ventilation effect, the ventilation mechanism 13 is in a ventilation state, and a ventilation channel is formed between adjacent louvers 5. As Figure 3 shown on the right side, when the device encounters rainy or snowy weather, in order to improve the protection effect of the device, the ventilation mechanism 13 is in a closed state, and adjacent louvers 5 are in contact with each other to form a baffle structure to block the ventilation slot. Specifically, the louver 5 includes a connecting plate and an extension plate, the extension plates are connected to both sides of the connecting plate, and the connecting rod 7 is connected to the connecting plate through a crank arm 6.

[0019] The driving member 11 drives the connecting rod 7 to move up and down, thereby adjusting the position of the louvers 5 and changing the heat dissipation area of the device. Among them, the driving member 11 can be an electromagnetic mechanism or an electric telescopic rod. A temperature sensor (not shown in the figure) and a humidity sensor (not shown in the figure) are configured inside the device. When the temperature or humidity is higher than the threshold value, the driving member 11 drives the connecting rod 7 to move to adjust the position of the louvers 5, so that the area of the ventilation channel formed between adjacent louvers 5 is the largest, so as to maximize the heat dissipation efficiency.

[0020] The ventilation mechanism 13 further includes a ventilation fan 12. The ventilation fan 12 is installed at the ventilation slot. The ventilation fan 12 is located inside the door panel 2. Starting the ventilation fan 12 can accelerate the air flow inside and outside the device, realize air exchange, and can further improve the heat dissipation efficiency and dehumidification efficiency of the device; in addition, the ventilation fan 12 can also clean the filter screen 8.

[0021] In addition, a dew collecting trough 9 is installed at the bottom of the ventilation slot. The dew collecting trough 9 has a funnel-shaped structure. A drain pipe 10 is connected to the bottom of the dew collecting trough 9, and the other end of the drain pipe 10 extends to the outside of the door panel 2. When the ventilation fan 12 dehumidifies, condensation may form at the louvers 5. When the condensation accumulates to a certain level, water droplets are formed and drip into the dew collecting trough 9 below the louvers 5. The condensation in the dew collecting trough 9 will be discharged to the outside of the device through the drain pipe 10, which can ensure the dryness inside the device.

[0022] As Figure 2As shown in the figure, the corresponding edges of the door frame 1 and the door panel 2 are in a mutually matching stepped shape. A sealing strip 3 is installed on the stepped edges of the door frame 1 and the door panel 2, and a sealing ring 4 is arranged between the stepped edges of the door frame 1 and the door panel 2. Through the structural design of the stepped structure and the sealing strip 3 and the sealing ring 4, the sealing performance between the door frame 1 and the door panel 2 is improved, and it can effectively reduce the entry of dust or water vapor into the equipment interior through the gap between the door frame 1 and the door panel 2.

[0023] During the transportation of the equipment configured with this door body structure, since the equipment is in a power-off state, at this time, the driving part 11 of the ventilation device 13 is in a power-off state, and the louvers 5 on the connecting rod 7 are in the closed state as shown on the Figure 3 right side, forming a baffle structure to block the ventilation slots. At this time, air convection exchange cannot occur between the inside and outside of the equipment, and it can effectively prevent the dust and water vapor in the convective air from entering the equipment.

[0024] When the equipment is running normally, the humidity sensor and the temperature sensor inside the equipment work all the time. When the humidity inside the equipment reaches a level that may affect the safe operation of the equipment, the humidity sensor controls the driving part 11 to push the connecting rod 7, and rotates the louvers 5 to the open state as shown on the Figure 3 left side through the crank arm 6. At this time, a ventilation channel is formed between adjacent louvers 5, and at the same time, the ventilation fan 12 is driven to start, discharging the high-humidity air inside the equipment to the outside of the equipment. At this time, if the humidity inside the equipment is relatively high (mainly in rainy and foggy weather), when the ventilation fan 12 is discharging moisture, condensation may form at the louvers 5. When the condensation accumulates to a certain extent, water droplets are formed and drip into the dew collection groove 9 below the louvers 5, and the condensation in the dew collection groove 9 is discharged to the outside of the equipment through the drain pipe 10.

[0025] When the temperature inside the equipment rises to the set value that requires ventilation and heat dissipation, the temperature sensor controls the driving part 11 to push the connecting rod 7, and rotates the louvers 5 to the open state as shown on the Figure 3 left side through the crank arm 6. At this time, a ventilation channel is formed between adjacent louvers 5, and at the same time, the ventilation fan 12 is driven to start, discharging the high-temperature air inside the equipment to the outside of the equipment to complete the heat discharge and temperature reduction of the equipment.

[0026] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
