[0019] The implementation principle of the test device for an air source heat pump heating and cooling unit in an embodiment of the present application is as follows: When in use, first open the cabinet door 3, then start the push rod motor I. The push rod motor I drives the mounting frame 7, the conveying wheel I 8 and the conveyor belt I 9 to move outside the test box 1, and then simultaneously drives the two rack bars II 20 to move to one side. The movement of the two rack bars II 20 simultaneously drives the two gear wheels II 21 to rotate, so that the rotating column II 17 drives the sprocket II 18 to rotate. The sprocket II 18 drives the sprocket I 16 to rotate through the chain I 19. The sprocket I 16 drives the rotating column I 15 to rotate. The rotating column I 15 drives the two gear wheels I 14 to rotate. The two gear wheels I 14 drive the rack bar I 13 to move to one side and drive the push plate 10 to move to one side, so that the push plate 10 pushes the push rod 11, the bracket 22, the conveying wheel II, the conveyor belt II 23 and the fixing block I 24 to move outside the test box 1; When the two conveyor wheels II, the conveyor belt II 23 and the fixed block I 24 completely leave the inside of the test box 1, the continuous movement of the push plate 10 will squeeze the rear end of the spring plate I 38, causing the rear end of the spring plate I 38 to drive the rack III 37 to move. The rack III 37 drives the gear III 36 to rotate, the gear III 36 drives the rotating column IV 35 to rotate, the rotating column IV 35 drives the two sprocket wheels IV 33 to rotate, and the two sprocket wheels IV 33 drive the two sprocket wheels III 32 to rotate through the two chains V 34, so that the two sprocket wheels III 32 drive the two rotating columns III 31 to rotate. The two rotating columns III 31 drive the two bevel gears IV 30 to rotate, the two bevel gears IV 30 drive the two bevel gears III 29 to rotate, the two bevel gears III 29 drive the two telescopic rods I to rotate, the two telescopic rods I drive the bevel gear I to rotate, the bevel gear I drives the bevel gear II to rotate, the bevel gear II drives the rotating column to rotate, and the rotating column drives the bracket 22 to rotate, thus enabling the conveyor belt II 23 to be inclined for easy feeding; At the same time, the rotating column II 17 drives the two sprocket wheels VI 46 to rotate. The two sprocket wheels VI 46 drive the two sprocket wheels V 45 to rotate through the two chains II. The two sprocket wheels V 45 drive the same rotating column V 44 to rotate, and the rotating column V 44 drives the two gears IV 42 to rotate, thus driving the rack IV 41 to move forward to the front side of the test box 1. At the same time, when the connecting plate 40 moves forward a certain distance, the continuous movement will squeeze the rear end of the spring plate II 47 and drive the rack V 48 to move to one side, causing the rack V 48 to drive the gear V 49 to rotate. The gear V 49 drives the rotating rod I 50 to rotate, the rotating rod I 50 drives one of the sprocket wheels VII 51 to rotate, and one of the sprocket wheels VII 51 drives the other sprocket wheel VII 51 to rotate through the chain III, causing it to drive the rotating rod II 52 to rotate. The rotating rod II 52 drives the bevel gear V 53 to rotate, the bevel gear V 53 drives the bevel gear VI 54 to rotate, the bevel gear VI 54 drives the telescopic rod II 55 to rotate, the telescopic rod II 55 drives the bevel gear VII 56 to rotate, the bevel gear VII 56 drives the bevel gear VIII 57 to rotate, and the bevel gear VIII 57 drives the rotating rod III 58 to rotate, and the rotating rod III 58 drives the auxiliary plate 59 to rotate; Then place the air source heat pump heating and cooling unit on the platform. By starting the motor VII, the output shaft of the motor VII drives the reciprocating screw II to rotate. The reciprocating screw II drives the two sliding plates III to approach each other, and at the same time drives the two limiting plates to approach each other, thus enabling the air source heat pump heating and cooling unit to be located at the center of the platform; Then, by starting the push rod motor two, the air source heat pump heating and cooling unit is made flush with the conveyor belt two 23. Then, start the motor one 60 and the hydraulic cylinder three 63. The two adjusting plates 68 can prevent the air source heat pump heating and cooling unit from shifting during transmission. At the same time, the hydraulic cylinder three 63 can push the air source heat pump heating and cooling unit onto the conveyor belt two 23 for transmission. The output shaft of the motor one 60 drives the screw one 61 to rotate, and the screw one 61 drives the sliding plate one 62 to move upward, which can drive the hydraulic cylinder three 63, the positioning plate one 64, and the adjusting plate 68 to move upward, continuously adjusting the height. Through the conveyor belt two 23, the air source heat pump heating and cooling unit can be transmitted to the conveyor belt one 9, and then through the conveyor belt one 9, the position of the air source heat pump heating and cooling unit inside the test box 1 can be adjusted; Then, connect the inlet pipe and the outlet pipe of the external refrigerant storage tank to the two interfaces at the top of the test box 1 respectively, and connect the water tank inlet pipe and the outlet pipe to the two interfaces on one side of the test box 1 respectively. Then, start the two hydraulic cylinders four 69. The two hydraulic cylinders four 69 drive the fixed block two 70, the positioning plate two 71, the clamping plate 72, the triangular shovel 73, and the components inside the fixed block two 70 and the positioning plate two 71 to move downward respectively, so that the triangular shovel 73 contacts the conveyor belt one 9. Then, start the two motors four 78. The output shafts of the two motors four 78 drive the two screws two 79 to rotate. The two motors four 78 can make the two positioning plates two 71, the four clamping plates 72, and the two triangular shovels 73 approach each other through the two U-shaped plates 80. Then, by starting the motor two 65, the output shaft of the motor two 65 drives the reciprocating screw one 66 to rotate. Through the two sliding plates two 67, the two clamping plates 72 can be made to approach each other, so as to clamp the air source heat pump heating and cooling unit. At the same time, the air source heat pump heating and cooling unit can be propped up by the two triangular shovels 73. Then, start the motor three 75. The output shaft of the motor three 75 drives one of the sprockets eight 76 to rotate. One of the sprockets eight 76 drives the other sprocket eight 76 to rotate through the chain four 77, making the annular plate 74 rotate, which can drive the air source heat pump heating and cooling unit to rotate, adjust the position of the notch of the air source heat pump heating and cooling unit, and facilitate the connection with the connector 27. Then, start the four hydraulic cylinders two 28 respectively to adjust the position of the connector 27 so that it corresponds to the notch of the air source heat pump heating and cooling unit. Then, start the corresponding hydraulic cylinder one 26 to make the connector 27 access the corresponding notch to form a cycle. Embodiment Two
