Two sliding blocks 57 extending above it are slidably installed inside the frame 56. The limiting of the frame 56 enables the sliding blocks 57 to always slide in a straight line. Two connecting rods 58 are rotatably connected to the top of the threaded block 54 and respectively rotatably connected to the tops of the two sliding blocks 57.

[0027] The installation mechanism 6 includes an installation frame 601. The opposite sides of the two sliding blocks 57 are fixedly installed with the installation frame 601. The inner top wall of the installation frame 601 is open. The front and rear ends of the installation frame 601 are respectively slidably connected to the front and rear sides of the inner wall of the installation seat 2. The inner bottom wall of the installation frame 601 is fixedly installed with two rectangular frames 602. The two rectangular frames 602 inside a single installation frame 61 are symmetrically distributed front and back. The inner bottom wall of the installation frame 601 is fixedly installed with a second servo motor 603 located between the two rectangular frames 602.

[0029] Two chutes adapted to the movement track of the installation frame 601 are opened on both the front and rear sides of the inner wall of the installation seat 2. The limit of the chutes ensures the stability of the installation frame 601 and prevents it from tilting. A rectangular groove adapted to the movement track of the limit rod 55 is opened on the inner bottom wall of the installation seat 2.

A slider 42 located on the right side of the fixed block 41 is slidably installed on the inner bottom wall of the base 1. A groove adapted to the movement track of the slider 42 is formed on the inner bottom wall of the base 1. The slider 42 extends to the inside of the groove and is slidably connected thereto, ensuring the stability of the slider 42 during movement and preventing its front-back position from shifting. A lifting plate 43 is slidably installed between the front and rear sides of the inner wall of the base 1. The mounting seat 2 is fixedly installed on the top of the lifting plate 43. A hydraulic cylinder 44 is fixedly installed on the inner bottom wall of the base 1. The hydraulic cylinder 44 is electrically connected to an external power supply and is controlled by an external program. The output end of the hydraulic cylinder 44 is fixedly connected to the slider 42. Two first inclined rods 45 are rotatably connected to the bottom of the lifting plate 43 and are rotatably connected to the top of the slider 42. Two slide rails 46 are fixedly installed on the bottom of the lifting plate 43. The slide rails 46 are used for limiting the second inclined rod 47. Two second inclined rods 47 are rotatably connected to the top of the fixed block 41 and are respectively slidably connected to the outer sides of the two slide rails 46. The intersection point of the first inclined rod 45 and the second inclined rod 47 is rotatably connected by a connecting shaft.

[0031] The inner top wall of the base 1 is designed to be open. Limiting chutes are formed on both the front and rear sides of the inner wall of the base 1. The size of the limiting chutes is adapted to the movement track of the lifting plate 43.

[0032] During use, when installing the main body 3 of the heat pump unit, place it on the top of the mounting base 2. By setting the adjusting mechanism 5 and the mounting mechanism 6, adjust the positions of the mounting block 608 and the pressing block 612 according to the size of the main body 3 of the heat pump unit. First, start the first servo motor 52 to drive the threaded rod 53 to rotate forward and backward. The threaded block 54 on its outer side makes a reciprocating linear motion back and forth under the limiting support of the limiting rod 55. In this way, the connecting rod 58 is pulled to tilt at an angle. The two connecting rods 58 respectively drive the two sliding blocks 57 to move relatively or away from each other inside the frame 56. The sliding block 57 drives the two mounting frames 601 to slide on the side wall of the mounting base 2. The two mounting mechanisms 6 as a whole are displaced, and the distance between the two mounting mechanisms 6 is adjusted according to the width of the main body 3 of the heat pump unit, completing the fixation of the left and right sides of the main body 3 of the heat pump unit by the mounting block 608. Secondly, start the second servo motor 603 to drive the reel 604 to rotate forward and backward, and the pull rope 606 can be wound or loosened. With the cooperation of the return spring 613, the pull rope 606 pulls the vertical rod 610 to slide up and down in the cylinder 609. In this way, the top plate 611 and the pressing block 612 are adjusted to move up and down, and move to fit the top of the main body 3 of the heat pump unit, and the top of the main body 3 of the heat pump unit can be limited and fixed. After the pressing block 612 is kept in contact with the main body 3 of the heat pump unit, continue to wind the pull rope 606, and the pull rope 606 will drive the front and rear moving blocks 605 to move relatively. With the cooperation of the telescopic spring 607, the moving blocks 605 drive the front and rear mounting blocks 608 to move relatively. In this way, the mounting blocks 608 fit the front and rear sides of the main body 3 of the heat pump unit and fix it. By setting the lifting mechanism 4, start the hydraulic cylinder 44 to push the slider 42 to move left and right. With the cooperation of the fixed block 41, change the inclination angles of the first inclined rod 45 and the second inclined rod 47. While the second inclined rod 47 is inclined, the top end of it slides outside the slide rail 46. In this way, the height of the lifting plate 43 is adjusted, and the height adjustment of the main body 3 of the heat pump unit is completed.

[0033] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] To sum up, for the heat pump unit that is convenient for installation and height adjustment, by setting the adjusting mechanism 5 and the mounting mechanism 6, when installing the main body 3 of the heat pump unit, place it on the top of the mounting base 2, adjust the positions of the mounting block 608 and the pressing block 612 according to the size of the main body 3 of the heat pump unit, and install and fix the main body 3 of the heat pump unit. Secondly, by setting the lifting mechanism 4, start the hydraulic cylinder 44 to adjust the height of the lifting plate 43 in cooperation with the first inclined rod 45 and the second inclined rod 47, and complete the height adjustment of the main body 3 of the heat pump unit, solving the problems that the four sides of the unit cannot be fixed, the installation is relatively unstable, resulting in the unit being prone to position deviation, affecting the use of the heat pump unit, secondly, the height cannot be adjusted, it cannot be applied to different height situations, and the convenience of the heat pump unit is reduced.
