Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Example 1, by Figure 1 This utility model relates to a non-contact drive dual-fan cooling heat pump, including a rear fan cover 1, a rear end cover 4 on the rear fan cover 1, a base 5 connected to the rear end cover 4, a support mechanism 6 at the bottom of the base 5, a front end cover 11 on the base 5, a stator 8 on the inner side of the base 5, a front bearing 10 on the front end cover 11, a rear bearing 3 on the rear end cover 4, a motor shaft 9 between the rear end cover 4 and the front bearing 10, a rotor 7 on the motor shaft 9, and a rear fan 2 at the rear end of the motor shaft 9, located inside the rear fan cover 1. The unit is equipped with a junction box 24, a main drive disk 12 is provided at the front end of the motor shaft 9, a main drive magnet 13 is provided on the main drive disk 12, a heat insulation pad 14 is provided on the front cover 11, a pump cover 15 is provided on the heat insulation pad 14, a pump body 16 and a mechanical seal 22 are provided on the pump cover 15, a driven magnetic conductor 19 is provided on the outer side of the main drive magnet 13, a driven disk 18 is provided on the driven magnetic conductor 19, a driven shaft 20 is provided on the driven disk 18, a driven support bearing 23 and an impeller 21 are provided on the driven shaft 20, and a central front fan 17 is provided at the front end of the driven disk 18. When the drive motor is powered on, the stator 8 generates a rotating magnetic field, which drives the rotor 7 to rotate, causing the main drive disk 12 and the main drive magnet 13 to rotate together. At this time, the main drive magnet 13 drives the driven magnetic conductor 19 to rotate in the air. Simultaneously, the driven disk 18 and the centrally mounted front fan 17 rotate under the drive of the integrated driven magnetic conductor 19, driving the impeller 21, which is mounted on the same axis, to rotate. The hot liquid is drawn in from the inlet and output from the outlet, generating a certain pressure, and transported to a specific location through the connecting pipe. During this process, the rear fan 2 cools the drive motor housing, and the centrally mounted front fan 17 dissipates the heat from the outer surface of the hot liquid pump body 16 through the front exhaust vent, preventing it from being conducted to the drive motor. With the combined effect of non-contact power transmission and the heat insulation pad 14, the high temperature of the working medium is isolated from the drive motor, ensuring its long-term reliable operation.

[0016] Specifically, by Figures 2-4 The support mechanism 6 includes a support plate 601 fixed to the bottom of the base 5. Support columns 605 are fixedly connected to the bottom of the support plate 601 near its four corners. Each support column 605 has a roller 604 at its bottom end. A frame 602 is provided at the bottom of the support plate 601, fixedly fitted onto the outside of each support column 605. Two uprights 6013 are symmetrically fixedly connected to the bottom of the frame 602. A base block 6015 is fixedly connected to the bottom end of each of the two uprights 6013. An annular groove 6014 is movably fitted onto the outside of each of the two uprights 6013. A lifting plate 603 is fixedly connected between the two annular grooves 6014. Two connecting columns 606 are symmetrically fixedly connected to the bottom of the lifting plate 603. A U-shaped plate 608 is fixedly connected to the bottom end of each of the two connecting columns 606. The bottoms of the two U-shaped plates 608 are symmetrically fixedly connected to... There are two rubber pads 607. Multiple balls 6016 are provided at equal angles on the inner side of the annular groove 6014. Each ball 6016 abuts against the outer side of the column 6013. Multiple balls 6016 are provided between the annular groove 6014 and the column 6013 to avoid direct contact between the annular groove 6014 and the column 6013 and reduce the friction between the annular groove 6014 and the column 6013 when the annular groove 6014 moves. Two guide columns 609 are symmetrically fixedly connected to the inner side of the sleeve 602. A guide plate 6011 is movably sleeved between the two guide columns 609. A movable plate 6012 is rotatably connected to the bottom of the guide plate 6011. The bottom of the movable plate 6012 is rotatably connected to the top of the lifting plate 603. An electric push rod 6010 is fixedly installed on the inner side of the sleeve 602. The guide plate 6011 is fixed to the output end of the electric push rod 6010. The entire device can be moved and transferred via various rollers 604. When the device needs to work, the electric push rod 6010 is first activated, which drives the guide plate 6011 to slide along the two guide columns 609. The movable plate 6012 drives the lifting plate 603 to move downward. At the same time, the two annular grooves 6014 slide downward along the two columns 6013 respectively to ensure the stability of the lifting plate 603 during movement. Then, the two connecting columns 606 drive the two U-shaped plates 608 to move downward respectively. At the same time, all rubber pads 607 descend until they are in close contact with the ground, achieving stable support for the entire device and ensuring the stability of the device during operation.
