Description

Technical Field

[0001] The utility model relates to the technical field of transformer cooling, in particular to a heat dissipation device for a transformer substation. Background Art

[0002] The transformer is the heart of the substation. When the temperature reaches above 70℃, cooling measures need to be taken. However, in hot weather such as summer, the temperature of the transformer can reach 80℃~95℃. If it reaches above 90℃, the transformer cannot withstand the load and will "strike" and be forced to cut off power. Therefore, external force must be used to cool it down.

[0003] The cooling mist cannon is one of the commonly used cooling equipment for transformers in substations. The working principle of the mist cannon is as follows:

[0004] It mainly uses a high-pressure water pump to transport water through a specific pipe to the atomizing nozzle of the fog cannon, and then the wind tube fan generates a strong airflow to transport the water mist produced by the nozzle out. These tiny mist-like water particles can be suspended in the air for a long time, thereby achieving the effect of cooling the transformer.

[0005] When the existing cooling mist cannon is cooling the transformer, it is mostly transferred to the vicinity of the transformer through the universal wheel. Since the substation is located below the transformer, it is mostly soil ground or paved with stones. The soil ground is relatively soft, and there are loose gaps between the stones at the stone paving site. This causes the universal wheel to easily sink on the soil ground or the stone paving site, which makes the cooling mist cannon run unsteadily when on the soil ground or the stone paving site. Therefore, most of the cooling mist cannons are placed on a cement ground far away from the transformer for use. In this case, a lot of water mist will be lost in the process of the water mist blown out from the cooling mist cannon to the transformer position. Based on this, in order to enable the cooling mist cannon to be stably placed on the soil ground or the stone paved ground, so that the cooling mist cannon can be closer to the transformer, a heat dissipation device for the substation is provided.

[0028] The anti-sinking assembly 2 includes a lifting unit and an anti-drifting unit. The lifting unit moves downward to increase the contact area with the ground, and the anti-drifting unit is used to increase the friction between the bottom of the lifting unit and the ground.

[0029] The lifting unit includes a fixed bottom plate 201, a screw 202, a rotating handle 204, a rectangular frame 205, a fixed top plate 206, and a horizontal pad 207;

[0030] The fixed base plates 201 are symmetrically fixed to both ends of the main chassis 101. The screw rods 202 are rotatably connected to the top of one of the fixed base plates 201 and protrude above the main chassis 101. The rotating handle 204 is fixed to the top of the screw rods 202.

[0031] The rectangular frame 205 is sleeved on the outside of the main chassis 101, and the fixed top plates 206 are symmetrically fixed to the two ends of the top of the rectangular frame 205. One of the fixed top plates 206 is threadedly sleeved on the outside of the screw 202. The screw 202 rotates to drive the fixed top plate 206 to move up and down to achieve the lifting operation of the rectangular frame 205.

[0032] The horizontal pad 207 is fixed to the bottom of the rectangular frame 205 and fits the bottom of the main chassis 101. The horizontal pad 207 moves downward to contact the ground, thereby increasing the contact area between the pad and the ground.

[0033] The lifting unit further includes a guide rod 203, which is fixed to the top of another fixed base plate 201, and another rotating handle 204 is slidably sleeved on the outside of the guide rod 203;

[0034] There are multiple transverse pads 207 , and the multiple transverse pads 207 are evenly distributed along the horizontal direction.

[0035] In this embodiment: It should be supplemented that: a fan and an atomizing nozzle are installed inside the atomizing barrel 103, a water pump and a generator are provided inside the main box 101, the generator is used to provide power for the water pump, the fan, and the electric push rod 104, the water pump is used to transport water to the atomizing nozzle to form water mist, the fan is used to blow the water mist to the transformer for cooling operation, and the electric push rod 104 is used to adjust and support the angle of the atomizing barrel 103;

[0036] When the cooling mist cannon 1 needs to be placed on a soil or gravel ground, the anti-sinking component 2 can be used to support the bottom of the main box 101 to prevent the universal wheel 105 on the cooling mist cannon 1 from sinking. The operation steps are as follows:

[0037] By rotating the rotating handle 204, the screw 202 is driven to rotate, and the screw 202 drives a fixed top plate 206 to move downward through the threaded structure. This fixed top plate 206 drives the rectangular frame 205 to move downward, and the rectangular frame 205 drives another fixed top plate 206 to move downward along the outer wall of the guide rod 203.

The large area of ​​contact prevents the universal wheel 105 from sinking, and the entire device can be stably placed on the soil ground or the ground paved with stones, and then can be closer to the transformer, which is used to reduce the loss during the water mist transmission process, and then further improve the cooling effect on the transformer.

[0038] Please refer to Figure 3 The anti-drift unit includes a cone block 208, which is fixed to the bottom of the horizontal pad 207.

[0039] A plurality of cone blocks 208 are evenly arranged at the bottom of a single transverse pad 207 . When the transverse pad 207 is attached to the bottom of the main chassis 101 , the bottom level of the cone blocks 208 is lower than the bottom level of the universal wheel 105 .

[0040] In this embodiment, when the horizontal pad 207 moves downward and contacts the ground, the cone block 208 is inserted into the gap between the soil or gravel, effectively increasing the friction between the ground and the device, thereby preventing the device from deflecting and further improving the operating stability of the device.

[0041] During daily use, the handle 204 is rotated in the opposite direction to move the horizontal pad 207 upward to fit the bottom of the main chassis 101. At this time, the cone block 208 is separated from the ground and will not affect the daily transfer of the device.
