[0030] Example 1: Reference Figure 1-3 As shown, the present invention provides a device for monitoring power quality in mines, comprising a power quality analyzer and a housing 1. One side of the housing 1 is open and is divided into an equipment compartment 3 and a heat dissipation compartment 4 by a heat dissipation plate 2. The equipment compartment 3 is a sealed compartment for installing the power quality analyzer.

[0031] A harness hole is also provided on the side wall of the equipment compartment 3 to connect the harness of the power quality analyzer out of the equipment compartment 3. A rubber sleeve is provided in the harness hole to seal the harness hole.

[0032] The heat dissipation chamber 4 is equipped with a water cooling pump 5 , a coolant tank 6 , a fan 7 and a power supply 8 .

[0033] Mounting blocks 9 are provided at both ends of the coolant tank 6 and the fan 7 , and mounting grooves 15 are provided on the shell wall of the housing 1 for mounting the mounting blocks 9 to fix the coolant tank 6 and the fan 7 .

[0034] The power supply 8 and the power quality analyzer are both connected to the lighting grid under the mine to provide electricity; the power supply 8 supplies power to the water cooling pump 5 and the fan 7.

[0035] The heat sink 2 includes a sealing frame 21 and aluminum plates 22 arranged on both sides of the sealing frame 21; the sealing frame 21 is a frame structure, and its two sides are connected to the aluminum plates 22, so that the interior of the heat sink 2 is a cavity structure.

[0036] The heat dissipation plate 2 is provided with connecting pillars 23 , and the connecting pillars 23 are welded to two sides of the sealing frame 21 .

[0037] Two C-shaped cylinders 11 are arranged opposite to each other on the inner side of the shell 1 for plugging in the connecting column 23 to fix the heat sink 2, thereby separating the shell 1 into the equipment compartment 3 and the heat dissipation compartment 4 through the heat sink 2.

[0038] A C-shaped sealing gasket 12 is provided in the inner wall of the C-shaped column 11, so that the connecting column 23 is inserted into the C-shaped column 11 to play a sealing role.

[0039] A shell cover 13 is provided on the open side of the shell 1, and a sealing gasket 14 is provided at the joint between the shell 1 and the shell cover 13.

[0044] When the coolant is in the heat sink 2 , it fully exchanges heat with the hot air in the equipment compartment 3 through the aluminum plate 22 .

[0045] The fan 7 is attached to the coolant tank 6 to dissipate heat from the coolant tank 6; at the same time, a fan 7 is also provided near the heat sink 2 in the equipment cabin 3 to better enable the gas circulation in the equipment cabin 3 to complete heat exchange with the heat sink 2.
