Description

Technical Field

[0001] The utility model relates to the technical field of cabin-type substations, in particular to a temperature-sensing ventilation mechanism for a prefabricated cabin substation. Background Art

[0002] As an integrated power facility, prefabricated cabin substation is widely used in urban power supply systems and industrial electricity. It consists of transformers, distribution equipment and control systems, and has the characteristics of modularization, mobility and rapid deployment. However, during the operation of prefabricated cabin substation, excessive internal temperature may cause equipment failure, damage and even fire and other safety hazards. Therefore, it is of great significance to effectively control the internal temperature of prefabricated cabin substation.

[0003] At present, the solutions for the internal temperature control of prefabricated cabin substations mostly use traditional ventilation equipment, such as using ventilation fans for ventilation and cooling. Since traditional dust covers are mostly fixedly installed on the ventilation unit and are inconvenient to remove, the fan blades and dust covers installed in the ventilation mechanism will inevitably adhere to a lot of dust after long-term use, thereby affecting the ventilation effect.

[0029] Reference Figure 1-6 The utility model provides a prefabricated cabin substation temperature sensing ventilation mechanism, comprising:

[0030] The main unit 100 , the ventilation unit 200 and the elastic unit 300 .

[0031] The main unit 100 includes a cabin 101 and a ventilation window 102 fixedly arranged on the upper right side of the cabin 101.

The controller 103 receives the sensor data and controls the temperature through the ventilation unit 200 according to the set threshold value, thereby achieving the effect of temperature sensing control. The temperature sensor 104 and the controller 103 in the utility model are often used in the field of substations and are inherent components of the temperature sensing ventilation mechanism of the substation. The working principle thereof is not described in detail here.

[0033] Furthermore, the connecting unit 300 includes two mounting blocks 301 fixedly mounted on both sides of the fixed bracket 201, each mounting block 301 is provided with a slide groove 302, the slide groove 302 is vertically slidably connected with a pull rod 305, the bottom end of the pull rod 305 is fixedly connected with a clamping block 303, the outer surface of the pull rod 305 is sleeved with a spring 304, the mounting block 301 is provided with a connecting block 306, the outside of the clamping block 303 is slidably connected with the inside of the connecting block 306, and a dust cover 307 is fixedly mounted on the left side of the connecting block 306, the dust cover 307 can effectively prevent dust and other impurities from entering the ventilation unit 200, protect the equipment and extend its service life, and through the design of the slide groove 302 and the clamping block 303 and other structures, the dust cover 307 can be flexibly disassembled for cleaning or replacement, thereby ensuring the efficient operation of the ventilation unit 200 and improving the efficiency of the ventilation equipment.

[0034] During use, the temperature inside the cabin 101 is first sensed by the temperature sensor 104, and the information is transmitted to the controller 103.

At the same time, the dust cover 307 can effectively prevent dust and other impurities from entering the ventilation unit 200, and when the dust cover 307 needs to be cleaned or replaced, the pull rod 305 can be pulled upward to drive the block 303 to move upward, thereby disengaging from the inside of the connecting block 306, so that the dust cover 307 can be disassembled, making it simple and convenient to clean or replace the dust cover 307, thereby ensuring the use effect of the fan blades 205 and the dust cover 307, thereby ensuring the effective control of the internal temperature of the prefabricated cabin substation.
