Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically an integrated fire-fighting fan control cabinet. Background Technology

[0002] Fire-fighting fans refer to industrial fans that can operate continuously for more than 60 minutes at 300℃ and for 20 hours at 100℃ without damage. They are primarily used in buildings with fire safety requirements, such as subways, tunnels, high-rise buildings, stadiums, underground shopping malls, and workshops, for fire smoke extraction and ventilation. In the event of a fire, the fans are generally controlled by automatic controllers. However, for safety reasons, most fire-fighting fans are also connected to control cabinets for manual control in special circumstances. The fire-fighting fan control cabinet is a metal cabinet that assembles switching equipment, measuring instruments, and other equipment according to electrical wiring requirements. Its layout should meet the requirements of normal power system operation. During normal operation, the circuit can be connected or disconnected using switches. In case of faults or abnormal operation, the circuit is cut off or an alarm is triggered by protective electrical devices. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions.

[0003] For example, Chinese utility model patent CN211958367U proposes an integrated fire-fighting fan control cabinet, including a cabinet door and a fan. The top of the cabinet door has a ventilation hole, and a support plate is installed at the bottom of the ventilation hole. Nuts are installed at both ends of the support plate. A handle is installed at one end of the cabinet door, and a storage box is installed at the bottom of the cabinet door. Screws are installed at the four corners of the storage box. A hinge is installed at one end of the cabinet door, and the right end of the hinge is connected to the cabinet body. The fan is located at the top inside the cabinet body, and a mesh cover is installed on the outside of the fan. A sponge layer is installed on the inside of the cabinet body, and adjustment plates are welded to both ends inside the cabinet body. Adjustment holes are opened on the surface of the adjustment plates, and a fixing plate is installed on the surface of the adjustment plates. This integrated fire-fighting fan control cabinet is equipped with a support plate. The design of the support plate is to easily support heavier objects such as electrical boxes, preventing them from falling during installation and increasing the stability of the installed objects.

[0004] However, the internal components of existing fire fan control cabinets operate at relatively high efficiency. Although the inner walls are equipped with heat dissipation vents, they are mostly passive heat dissipation and cannot actively cool the internal temperature. This can easily lead to damage to internal components due to excessive temperature and may even cause a fire, thus reducing efficiency and increasing costs. Therefore, we propose an integrated fire fan control cabinet with heat dissipation function. Utility Model Content

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figures 1-6 This application provides an integrated fire-fighting fan control cabinet, characterized in that it includes a cabinet body 100, a cabinet door 110 rotatably connected to one side of the cabinet body 100, a base 120 at the bottom of the cabinet body 100, a controller 130 on one side of the cabinet door 110, a honeycomb-shaped air inlet 210 on the lower half of one side of the cabinet door 110, a filter screen 200 on one side of the cabinet door 110 located on the honeycomb-shaped air inlet 210, a fan 400 on the inner wall of the cabinet body 100, a cable tray 300 on the inner wall of the cabinet body 100 located below the controller mounting plate, an air outlet 140 on the top of the cabinet body 100, a heat dissipation mechanism 600 fixed to the top of the air outlet 140 by bolts 620, the heat dissipation mechanism 600 including a U-shaped block 610, a guide plate 630 penetrating through the side wall of the U-shaped block 610, and a temperature sensor 800 on the top of the controller inside the cabinet body 100.

[0033] During use, first rotate the guide plate 630 to a suitable angle, then open the cabinet door 110 and install the fan 400 on the left and right side walls of the cabinet 100. Then, insert the wires plugged into the bottom of the internal controller into the wire slot 300 to make the wires neat and avoid tangling. Then close the cabinet door 110. When the device is running, the contactors, relays and other components inside the device (not shown in the existing structural diagram) generate heat. At this time, the honeycomb-shaped air inlet 210 on one side of the cabinet door 110, the air outlet 140 on the top of the cabinet 100 and the guide plate 630 installed in the air outlet 140 form a gas heat dissipation channel to dissipate heat inside the device. If the heat dissipation is slow and the temperature reaches a certain threshold, the temperature sensor 800 installed inside the device will turn on the fan 400 through electrical connection. The fan 400 blows air to accelerate the air flow. The air is discharged along the heat dissipation channel to the top along the guide plate 630 to prevent the internal temperature of the device from becoming too high.

[0034] In some embodiments, a T-shaped opening is provided on one side of the fan 400, and a T-shaped slide rail 410 is provided on the inner side wall of the cabinet 100, with the T-shaped slide rail 410 embedded in the T-shaped opening.

[0035] During use, the fan 400 slides into the T-shaped slide rail 410 on one side of the cabinet 100 through a T-shaped opening on one side, which facilitates the installation and replacement of the cabinet 100. The fan 400 and the T-shaped slide rail 410 are interference fit.

[0036] In some embodiments, a dehumidifier 500 is embedded on one side of the T-shaped slide rail 410.

[0037] During use, the dehumidifier 500 can be turned on. The dehumidifier 500 draws humid air into the machine through its internal air intake device. The air is rapidly cooled as it passes through the semiconductor cooling chip of the refrigeration component. When the air temperature drops below the dew point, the moisture condenses into water droplets and is collected in the collection bottle at the bottom, keeping the inside of the cabinet 100 dry and preventing damage to the internal electronic components caused by moisture. The collection bottle inside the dehumidifier 500 needs to be cleaned regularly. The model is Ecor Pro RD-280Y.

[0038] In some embodiments, a groove 900 is provided on one side of the cabinet door 110, a spring 910 is provided at the bottom of the groove 900, the bottom compression spring 910 of the filter screen 200 is engaged in the groove 900, and a micro vibration motor 920 is provided at the top of the filter screen 200.

[0039] During use, the bottom of the filter screen 200 presses against the spring 910 at the bottom of the groove 900 and is then engaged in the groove 900. After the device has been used for a period of time, the micro vibration motor 920 at the top of the filter screen 200 can be opened. The top of the filter screen 200 has an installation groove, and the micro vibration motor 920 is fixed in the installation groove with screws (the installation groove is not shown in the figure). The micro vibration motor 920 vibrates and drives the filter screen 200 to vibrate, shaking off the dust on its surface and achieving a self-cleaning effect.

[0040] In some embodiments, a short rod 640 is provided on one side of the guide plate 630, the short rod 640 passes through the loop block 610 and is inserted into the side wall of the air outlet 140.

[0041] During use, the guide plate 630 is connected to the side wall of the air outlet 140 via a short rod 640 through the loop block 610, allowing the guide plate 630 to rotate relative to the loop block 610 and the air outlet 140. This facilitates the adjustment of the angle of the short rod 640, enabling it to be adjusted to a suitable angle in different environments. In high-temperature environments, the angle can be increased to 30°~45° to extend the airflow path and enhance heat dissipation. In high-humidity environments, the angle can be decreased to 15°~30° to accelerate the removal of moisture.

[0042] In some embodiments, a crossbar 700 is provided on one side of the bottom of the guide plate 630, a telescopic rod 710 is provided on one side of the crossbar 700, an adjusting rod 720 is provided on one side of the telescopic rod, and a square groove 730 is provided on the top of the cabinet. The adjusting rod 720 passes through the square groove 730 and is hinged to its inner wall.

[0043] During use, the adjustable rod 720 can be rotated, which in turn drives the telescopic rod 710 to move. The telescopic rod 710 then moves the crossbar 700, which in turn drives the guide plate 630 on one side to rotate, thus facilitating the adjustment of the angle of the guide plate 630.

[0044] In some embodiments, the top of the cabinet 100 is provided with a plurality of card slots 740 on one side of the square groove 730.

[0045] During use, when adjusting the angle of the guide plate 630 by rotating the adjusting rod 720, the adjustment can be made according to the slot 740 set on one side of the square groove 730. First, pull the adjusting rod 720 to one side, then rotate it and push it into the slot 740. The slots 740 are spaced at 5 degrees, which makes it easy to adjust the guide plate 630 to a fixed angle and then fix it.

[0046] In some embodiments, the deflector 630 is arc-shaped.

[0047] During use, the fan 400 is turned on to accelerate the air flow. The air is discharged upward along the guide plate 630, which has an arc-shaped design. The arc-shaped design suppresses the formation of vortices through the smooth transition of curvature, keeps the airflow directional, reduces collision loss, and improves the heat dissipation efficiency of the device.
