DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] Working principle: When a heat pump unit 2 fails and needs maintenance, the personnel controls the corresponding hydraulic push rod 4 to operate, and the hydraulic push rod 4 drives the heat pump unit 2 to move out from multiple side-by-side heat pump units 2, effectively expanding the operating space of the maintenance personnel, making it convenient for the personnel to inspect or replace the heat pump unit 2, and effectively improving the maintenance efficiency of the heat pump unit 2.

[0023] Example 2: Please refer to Figure 4 This embodiment further explains Example 1. The valve structure 8 includes a ball valve 801 that can rotate inside the connecting pipe 5 and the auxiliary pipe 7. A rubber ball sleeve 802 is fixedly sleeved on the outer side of the ball valve 801. Flow holes are provided on the ball valve 801 and the rubber ball sleeve 802. A positioning tube 803 is movably sleeved on the outer side of the rubber ball sleeve 802. The rubber ball sleeve 802 can increase the sealing between the ball valve 801 and the positioning tube 803.

[0024] See also Figure 3 , Figure 4 The two positioning tubes 803 are fixedly connected to the connecting tube 5 and the auxiliary tube 7 respectively. A connecting shaft 804 is fixedly embedded in the center of the upper end of the spherical valve 801, and the two connecting shafts 804 are rotatably connected to the connecting tube 5 and the auxiliary tube 7 respectively through sealed bearings. The sealed bearings are conducive to smoother rotation of the spherical valve 801. The upper end of the connecting shaft 804 is fixedly connected to a gear 805.

[0025] See also Figure 3 The driving structure 9 includes a movable tube 901 movably sleeved on the outside of the connecting tube 5 and the auxiliary tube 7. The upper end of the movable tube 901 is provided with an avoidance groove for avoiding the connecting shaft 804. Two symmetrically distributed top rods 902 are fixedly installed on the outside of the movable tube 901. A tooth plate 903 is installed on the outside of the gear 805, and the tooth plate 903 is fixedly connected to the movable tube 901.

[0026] See also Figure 3 The two movable tubes 901 are fixedly connected with a ring 904 at one end away from each other, and the side of the ring 904 away from the movable tube 901 is movably abutted with a spring 905, which can drive the movable tube 901 to move, and the two springs 905 are movably sleeved on the outside of the connecting tube 5 and the auxiliary tube 7 respectively.

[0027] See also Figure 3 One end of the spring 905 away from the collar 904 is movably abutted against a retaining ring 906, the collar 904 can move with the movable tube 901, and the two retaining rings 906 are fixedly sleeved on the outside of the connecting tube 5 and the auxiliary tube 7 respectively.

[0028] In this embodiment: during the process of the hydraulic push rod 4 driving the heat pump unit 2 to move, the connecting pipe 5 gradually moves away from the auxiliary pipe 7. During this process, the spring 905 drives the movable pipe 901 and the tooth plate 903 to move back and reset. During the movement, the tooth plate 903 drives the ball valve 801 to rotate 90° through the gear 805. At this time, the flow hole on the rubber ball sleeve 802 of the ball valve 801 rotates to the inside of the positioning pipe 803, and the entity part of the rubber ball sleeve 802 blocks the two ends of the positioning pipe 803, so that when the heat pump unit 2 is moved out, the connecting pipe 5 and the auxiliary pipe 7 are automatically closed, without the need to empty the entire hydraulic circuit, which is more convenient to use;

[0029] When the connecting pipe 5 is docked with the auxiliary pipe 7, the tooth plate 903 will drive the ball valve 801 to rotate through the gear 805. The flow hole on the ball valve 801 coincides with the port of the positioning pipe 803. At this time, the connecting pipe 5 and the auxiliary pipe 7 are in a flow state. After the heat pump unit 2 is reset, the personnel inserts the positioning pin on the base plate 1 to position the heat pump unit 2 and reduce the pressure on the hydraulic push rod 4.

[0030] Example 3: Please refer to Figure 3 This embodiment further explains the first embodiment. One end of the auxiliary pipe 7 close to the connecting pipe 5 is fixedly connected to the butt-joint pipe 10. Two symmetrically distributed retaining rings 11 are fixedly sleeved on the outside of the connecting pipe 5. A rubber ring 12 is movably sleeved on the outside of the connecting pipe 5, and the rubber ring 12 is located between the two retaining rings 11. The rubber ring 12 can rotate on the outside of the connecting pipe 5, and the rubber ring 12 can movably fit with the inner wall of the butt-joint pipe 10.

[0031] In this embodiment: when the two push rods 902 are just fitted together, the connecting tube 5 is inserted into the inside of the butt joint tube 10, and the rubber ring 12 is against the inner wall of the butt joint tube 10, which can effectively enhance the sealing between the butt joint tube 10 and the connecting tube 5. When the connecting tube 5 continues to move, the butt joint tube 10 can drive the rubber ring 12 to move outside the connecting tube 5. The rubber ring 12 can rotate during the movement, which can effectively reduce the friction resistance between the rubber ring 12 and the butt joint tube 10.
