Since a universal wheel 6 is provided under the movable base plate 2, the universal wheel 6 can adjust the position of the water source heat pump unit body 1. By starting the hydraulic cylinder 7, the buffer base 3 can be driven to move downward, thereby lifting the entire water source heat pump unit body 1, and the universal wheel 6 is away from the ground to prevent the water source heat pump unit body 1 from moving. Adjustable height adjustment plates 4 are provided at the four corners. The adjustment plates 4 are used in conjunction with the buffer base 3 to increase the friction between the ground and the base of the water source heat pump unit body 1, thereby improving the stability of the water source heat pump unit body 1.

[0023] As a further implementation scheme of the above technical scheme: the fixing nut 10 is rotated on the adjustment plate 4 through the connecting bearing 12, and a rubber pad 13 is provided at the bottom of the adjustment plate 4. When the fixing nut 10 rotates, the distance between the adjustment plate 4 and the movable bottom plate 2 can be changed, thereby adjusting the corner height of the water source heat pump unit body 1 according to the terrain, so that the water source heat pump unit body 1 is in a horizontal state.

[0024] As a further implementation scheme of the above technical scheme: the bottom end surface of the rubber pad 13 is provided with a plurality of grooves which are evenly distributed at equal distances. The provision of the rubber pad 13 can increase the friction between the ground and the leveling plate 4 .

[0025] As a further implementation scheme of the above technical scheme: the buffer base 3 is lifted and lowered on the movable base plate 2 by the hydraulic cylinder 7. The hydraulic cylinder 7 can adjust the height between the buffer base 3 and the movable base plate 2.

When the water source heat pump unit body 1 falls, the ground contacts the buffer base 3 first, which can play a certain protective role. The height of the buffer base 3 can be adjusted by the hydraulic cylinder 7. When the universal wheel 6 extends out of the movable hole 8, the universal wheel 6 can drive the entire water source heat pump unit body 1 to move its position, which is convenient for subsequent docking with water pipes and pipelines. Rotating the hexagonal adjusting pieces 5 on the four corners can drive the fixing nut 10 to rotate. The fixing nut 10 rotates on the adjusting plate 4 through the connecting bearing 12, changes the distance between the adjusting plate 4 and the movable bottom plate 2, and adjusts the corner heights of the water source heat pump unit body 1 according to the terrain to make the water source heat pump unit body 1 in a horizontal state. When the bottom height of the water source heat pump unit body 1 is fixed, the hydraulic cylinder 7 can be started again. The hydraulic cylinder 7 pushes the buffer base 3 to move downward and fit closely to the ground to prevent the water source heat pump unit body 1 from moving.
