Description

Technical Field

[0001] The present application relates to the technical field of ventilation and heat dissipation, and in particular to an intelligent ventilation device. Background Art

[0002] When an electrical container or electrical cabinet is in operation, the electrical components inside it usually release a lot of heat. Therefore, ventilation holes need to be opened in the electrical container or electrical cabinet to ventilate and dissipate the internal electrical components to ensure the normal operation of the equipment. However, since electrical containers or electrical cabinets are often replaced in different working scenes, they need to face many different environments during transportation, especially during road transportation, they will experience strong winds, rain, snow and other weather conditions. If the ventilation holes are kept open, the protective performance of the equipment cannot be guaranteed. The present application proposes an intelligent ventilation device that is suitable for effectively sealing the internal electrical components of an electrical container or electrical cabinet during transportation and dissipating the internal electrical components of the electrical container or electrical cabinet during operation. Summary of the invention

[0003] In view of this, the present application proposes an intelligent ventilation device.

[0041] Here, it should be noted that the installation frame 100 is suitable for installing the whole at the position to be installed, and the hinged setting of the ventilation plate 200 and the installation frame 100 is suitable for opening or closing the installation frame 100 at any time as needed, so as to facilitate ventilation and heat dissipation or protective isolation of the inside of the equipment. The shutter 300 serves as a protective barrier, and air can flow through the shutter 300. While achieving uniform ventilation, it is filtered to improve the protection level and effectively prevent large impurities from being directly sucked into the equipment. The window opener 400 is suitable for driving the ventilation plate 200 to produce a rotational motion, thereby realizing the tilting and buckling of the ventilation plate 200. The present application is widely applicable to ventilation and heat dissipation in closed environments such as houses, cabinets, and boxes. It should be noted here that, when in use, the present invention is installed on the side wall or door panel of the container 1000. When the ambient air temperature rises and reaches a preset high temperature, the window opener 400 drives the ventilation plate 200 to rotate to open the ventilation plate 200, and the high-temperature gas in the container 1000 can flow out of the container 1000, so that the working environment of the equipment remains at a normal temperature, thereby increasing the service life of the equipment; when the container 1000 is in the process of transportation and does not need to dissipate heat, the ventilation plate 200 is buckled on the mounting frame 100 to seal the interior of the container 1000 to prevent rain, snow, impurities, dust, etc. from entering the interior of the container 1000. The present application has strong protective sealing performance while meeting the effective heat dissipation inside the container 1000.

[0043] In one possible implementation, Figure 3 As shown, a sealing ring 120 is provided on the mounting plate 110. The main body of the sealing ring 120 is a rectangular ring structure. The sealing ring 120 is arranged on the side of the mounting plate 110 facing the ventilation plate 200 and is arranged around the window 111. It should be noted that in order to improve the sealing performance between the ventilation plate 200 and the mounting plate 110, the sealing ring 120 is arranged on the mounting plate 110 so that the ventilation plate 200 and the mounting plate 110 can be effectively contacted when the ventilation plate 200 is covered on the mounting frame 100.

[0044] In a possible implementation, the ventilation plate 200 and the mounting plate 110 are rotatably connected via two or more first hinges 800.

The first hinge 800 is provided with a rotating shaft 810. Figure 8 As shown, the rotating shaft 810 is fixedly connected to the side of the ventilation plate 200 , and the ventilation plate 200 can be rotated relative to the mounting plate 110 under the action of the first hinge 800 .

[0045] Furthermore, there are three first hinges 800 in total, and the three first hinges 800 are respectively fixedly connected to the mounting plate 110 by bolts 820. The three first hinges 800 are evenly arranged on the top edge of the mounting plate 110.

The shape of the pressure ring 210 matches the shape of the sealing ring 120 and the position of the pressure ring 210 on the ventilation plate 200 corresponds to the position of the sealing ring 120 on the mounting plate 110. When the ventilation plate 200 is buckled on the mounting plate 110, the pressure ring 210 presses the sealing ring 120 to improve the sealing performance between the ventilation plate 200 and the mounting frame 100 and the mounting plate 110.

When the window frame 310 is embedded in the window 111 of the mounting plate 110, the frame edge contacts the mounting plate 110 and is fixedly connected to the mounting plate 110, thereby improving the overall installation stability of the window frame 310.

[0049] In a possible implementation, the angle between the surface where the fan blade 320 is located and the horizontal plane is 45 degrees to 80 degrees. Preferably, the angle between the surface where the fan blade 320 is located and the horizontal plane is 60 degrees.

[0050] In a possible implementation, it further includes: a dustproof net 600; the dustproof net 600 is arranged on the side of the shutter 300 away from the ventilation plate 200. It should be noted that the dustproof net 600 can effectively filter fine impurities, dust, etc. in the external environment, clean the air flowing through, and avoid pollution to the inside of the device.

[0051] Furthermore, the dustproof net 600 is embedded in the window frame 310 of the shutter 300 .

[0052] In a possible implementation, the invention further includes: a locking device; the locking device is arranged on a side of the ventilation plate 200 facing the mounting frame 100. It should be noted that when the ventilation plate 200 is fastened to the mounting frame 100, in order to prevent the ventilation plate 200 from flipping up due to loose fastening, the locking device is arranged on the ventilation plate 200, thereby improving the stability of the ventilation plate 200 fastened to the mounting frame 100.

When the ventilation plate 200 is buckled in the mounting frame 100, the clamp 230 probes into the through hole 112 of the mounting plate 110 and holds the mounting plate 110 tightly.

[0053] In a possible implementation, the auxiliary pushing device 500 is further included; the auxiliary pushing device 500 is arranged between the mounting frame 100 and the ventilation plate 200. Here, it should be noted that the auxiliary pushing device 500 is suitable for assisting the opening of the ventilation plate 200, and the auxiliary pushing device 500 cooperates with the window opener 400 to ensure the smooth opening and closing of the door panel.

[0054] In a possible implementation, the auxiliary pushing device 500 uses a pneumatic spring rod. Fig.13 As shown, one end of the pneumatic spring rod is hinged to the mounting plate 110 in the mounting frame 100 through a second hinge 510 , and the other end of the pneumatic spring rod is hinged to the ventilation plate 200 through a second hinge 510 .

When the window opener 400 drives the ventilation plate 200 to rotate and open, the pneumatic spring rod is pushed out to assist the opening of the ventilation plate 200. When the window opener 400 drives the ventilation plate 200 to rotate and close, the pneumatic spring rod is retracted to assist the closing of the ventilation plate 200.
