[0004] An existing digital variable frequency heat pump chiller with a de-icing structure has the following shortcomings:

[0005] Because the generator set is applicable to a wide range of locations, it often needs to be moved in actual use. However, the existing technology lacks a corresponding moving structure, and each move requires the use of an external crane or the cooperation of multiple people to complete the task. This not only increases the difficulty and cost of the move, but also consumes a lot of manpower and time, which is extremely inconvenient in actual operation and seriously affects the efficiency and convenience of the generator set's relocation.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figures 1-4This utility model provides a technical solution: a digital variable frequency heat pump chiller unit with a de-icing structure, including a moving mechanism 1, with an equipment mechanism 2 fixedly installed on the outer wall of the moving mechanism 1; the moving mechanism 1 includes a fixed block 101 and a connecting plate 118, a set of servo motors 119 fixedly installed on the top of the fixed block 101, a set of lead screws 117 fixedly connected to the output end of the servo motors 119, a set of threaded cylinders 116 threadedly connected to the outer wall of the lead screws 117, and sliding grooves 108 are provided on the inner wall of the connecting plate 118. The inner wall of the groove 108 is slidably connected to a slider 111, and the outer wall of the slider 111 is fixedly connected to a set of first movable plates 103. The bottom of the first movable plates 103 is fixedly connected to a first spring 104, and one end of the first spring 104 is fixedly connected to a second movable plate 106. The outer walls of the first movable plates 103 and the second movable plates 106 are rotatably connected to a rotating shaft 112. Through the above components, the high-strength moving wheels 109 can be quickly driven to move up and down, so as to lift the equipment mechanism 2 and facilitate the user to move it.

[0025] like Figure 2 As shown, the outer wall of the fixed block 101 is fixedly connected with a reinforcing block 110, and the bottom of the threaded cylinder 116 is fixedly connected to the bottom of the first movable plate 103. Through the reinforcing block 110, the connection between the fixed block 101 and the unit body 201 is made more stable.

[0026] like Figure 2 and Figure 3 As shown, connecting plates 105 are fixedly connected to the outer wall of the rotating shaft 112. One end of the first spring 104 is fixedly connected to the top of the second movable plate 106, and the other end of the first spring 104 is fixedly connected to the bottom of the first movable plate 103. Through the connecting plates 105 and the rotating shaft 112, the second movable plate 106 can be moved up and down stably, thus playing a guiding role.

[0027] like Figure 2 As shown, the inner wall of the slide groove 108 is fixedly connected with a limit rod 102, and the outer wall of the limit rod 102 is slidably connected to the inner wall of the slider 111. By setting the limit rod 102, the stability of the slider 111 when it moves up and down in the slide groove 108 can be improved, which indirectly ensures that the high-strength moving wheel 109 can move up and down stably.

[0028] like Figure 3 As shown, the bottom of the second movable plate 106 is fixedly connected to a connecting column 107, and a damper 113 is fixedly installed on the inner wall of the connecting column 107. A second spring 114 is sleeved on the outer wall of the damper 113. Through the damper 113 and the second spring 114, the damping and buffering purpose can be achieved, reducing the impact on the equipment mechanism 2 during movement.

[0029] like Figure 3and Figure 4 As shown, each shaft end of the damper 113 is fixedly connected to a connecting rod 115, and the bottom of each connecting rod 115 is rotatably connected to a high-strength moving wheel 109. The high-strength moving wheel 109 facilitates the user to move the whole unit and improves the overall flexibility.

[0030] like Figure 4 As shown, the equipment mechanism 2 includes a unit body 201. A PLC controller 202 is fixedly installed on the top of the unit body 201. A set of air inlet pipes 203 are fixedly connected to the top of the unit body 201. A set of dustproof nets 204 are fixedly connected to the inner wall of the air inlet pipes 203. The PLC controller 202 is electrically connected to the components to control the opening and closing of the components.

[0031] The device's operation and working principle are as follows: After the servo motor 119 is powered on, it rotates, driving the lead screw 117 to rotate. Since the lead screw 117 is threadedly connected to the threaded cylinder 116, the threaded cylinder 116 moves up and down along the lead screw 117. The bottom of the threaded cylinder 116 is fixed to the first movable plate 103, thereby driving the first movable plate 103 to move up and down. At this time, the slider 111 slides up and down within the slide groove 108. The first movable plate 103 is connected to the second movable plate 106 via the rotating shaft 112 and connecting plate 105, thus realizing the lifting and lowering of the high-strength moving wheel 109. When the high-strength moving wheel 109 descends to contact the ground, it can lift the entire assembly, allowing it to be moved to any location via the high-strength moving wheel 109, improving the overall flexibility. When the unit moves, ground bumps will cause the high-strength moving wheels 109 to be impacted. This impact is transmitted to the damper 113 and the second spring 114 through the connecting rod 115. The damper 113 can absorb the vibration energy, while the second spring 114 acts as a buffer, reducing the impact of vibration on the equipment mechanism 2. At the same time, the first spring 104 can also absorb vibration to a certain extent, further protecting the precision components inside the unit. In addition, the PLC controller 202 is electrically connected to the components and can control the opening and closing of components such as the servo motor 119, realizing the overall control of the moving mechanism 1 and the equipment mechanism 2. For example, the servo motor 119 can be started by the PLC controller 202 to complete the lifting and lowering operation of the moving wheels, so as to facilitate the movement and positioning of the unit.

[0032] The servo motor 119, the unit body 201, and the PLC controller 202 used in this application are all common conventional equipment on the market and are well known to those skilled in the art. The unit body 201 is a YCAE-D series (such as YCAE065). In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. Regarding their settings, installation, and electrical connection methods, those skilled in the art can perform debugging operations according to the corresponding product instruction manuals, so they will not be described in detail here.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
