[0029] The protective housing is also provided with a counterweight adjustment block 3; the side wall of the protective housing 1 is provided with threaded holes, and a plurality of counterweight adjustment blocks 3 are connected to the threaded holes through quick-release bolts. Figure 4 As shown, the counterweight adjustment block 3 is installed on the inner side of the protective shell. The existing mining transport vehicles use heavy and large lead-acid batteries; using lightweight lithium power sources as the power source of the mining transport vehicles, it is necessary to increase the counterweight to keep the adhesion gravity of the mining transport vehicles in compliance with the requirements. The structure of the counterweight adjustment of the present application is simple and easy to adjust. It only needs to thread the counterweight adjustment block 3. By changing the number of counterweight adjustment blocks 3, the counterweight of the power source can be conveniently and accurately matched and adjusted, which is convenient for adaptation to various mining transport vehicles.

[0030] As another adjustment method, the weight of the power box of different types of mining transport vehicles is different; when the overall size of the protective shell 1 remains unchanged, protective shells 1 with different wall thicknesses are selected to make the overall weight of the power supply after installation match the mining transport vehicle.
