Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to a mobile vacuum pump platform. Background Technology

[0002] In the face of tightening energy supplies and increasingly stringent environmental protection requirements, people are constantly seeking new energy sources that are both energy-efficient and environmentally friendly. Heat pumps are one such new energy source. Because heat pumps can transfer low-temperature heat energy to high-temperature heat energy, they can make extensive use of heat from natural resources and waste heat resources, effectively saving primary energy required for both residential and industrial use. As a new heating technology, it has not only received widespread attention but has also been rapidly applied to practical engineering projects with excellent results.

[0003] To ensure the stable operation of a heat pump system, it is necessary to inspect and maintain its components and heat exchange piping. However, if the vacuum level of the heat pump system cannot be quickly restored after maintenance, or if chemicals such as aluminum hydroxide are not added in a timely manner, oxidation and corrosion of the heat exchange pipes can occur. Currently, although the vacuum level of the heat pump system can be restored after maintenance using existing vacuum pumps, the relocation and fixed connection of these pumps require significant manpower and resources before operation, thus hindering a rapid restoration of the vacuum level. Therefore, achieving rapid vacuum restoration of the heat pump system is a pressing technical problem that needs to be solved. Utility Model Content

[0038] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

[0039] Figures 1 to 3 This is a schematic diagram of the structure of a mobile vacuum pump platform according to an embodiment of the present invention, as shown below. Figure 1 , Figure 2 and Figure 3 As shown, the mobile vacuum pump platform includes at least a mobile platform, a vacuum pump 200, and an electrical control box 300.

[0040] A mobile platform includes a support platform 110 and wheels 120. The wheels 120 are mounted on the support platform 110 and are used to move the mobile vacuum pump platform. A vacuum pump 200 is mounted on the support platform 110, and the output end of the vacuum pump 200 is connected to the air inlet of an external gas source heat pump. A power distribution box 300 is mounted on the support platform 110, and the power input end of the power distribution box 300 is connected to the power output end of the heat pump system. The power output end of the power distribution box 300 is connected to the power input end of the vacuum pump 200.

[0041] In the above embodiment, both the vacuum pump 200 and the power distribution box 300 are mounted on the support platform 110, and the wheels 120 are also mounted on the support platform 110. The movement of the wheels 120 allows the entire mobile vacuum pump platform to be moved, thus enabling rapid deployment of the vacuum pump 200. Furthermore, before the vacuum pump 200 is moved, the power output terminal of the power distribution box 300 located on the support platform 110 is connected to the power input terminal of the vacuum pump 200. Therefore, when deploying the mobile vacuum pump platform, only the power input terminal of the power distribution box 300 of the mobile vacuum pump platform moved to the working position needs to be connected to the power output terminal of the heat pump system. This mobile vacuum pump platform enables rapid movement and deployment of the vacuum pump 200, saving the connection steps between the vacuum pump 200, the power distribution box 300, and the heat pump system. This not only saves manpower and resources but also improves the vacuum recovery speed of the heat pump system.

[0042] In addition, to make the mobile vacuum pump platform adaptable to different terrains, the mobile platform also includes adjustable height support legs 130, which are disposed on the support platform 110 and used to adjust the levelness of the support platform 110. In this embodiment, the adjustable height support legs 130 are used to adjust the height and levelness of the support platform 110, thereby achieving rapid adjustment of the height and levelness of the vacuum pump 200. For example, there may be multiple adjustable height support legs 130, which are respectively disposed at multiple corner positions of the support platform 110, that is, multiple adjustable height support legs 130 are used to adjust the height of multiple corners of the support platform 110, thereby ensuring the levelness of the support platform 110. It is understood that the structural shape of the mobile platform in the above embodiment is not limited, and the number of adjustable height support legs 130 can be adaptively set based on the structural shape of the mobile platform.

[0043] In some embodiments of this utility model, the support platform 110 is a rectangular platform, and the number of adjustable height supports 130 is even, with the even number of adjustable height supports 130 symmetrically arranged on opposite sides of the rectangular platform. Figure 6 and Figure 7 As shown, the support platform 110 is specifically a rectangular plate, with wheels 120 positioned at the bottom. The vacuum pump 200 and the electrical distribution box 300 are positioned above the rectangular plate. The number of wheels 120 can be four, and the four wheels 120 are detachably connected to the rectangular plate via wheel brackets. Figure 3 As shown, the four wheels 120 are arranged symmetrically with respect to the center plane of the rectangular plate. In this embodiment, an even number of adjustable height support legs 130 are symmetrically arranged on the front and rear sides of the rectangular plate, specifically the front and rear sides of the rectangular plate. Figure 6 and Figure 7 The top and bottom sides of the rectangular plate shown.

[0044] Furthermore, the rectangular platform is provided with a plurality of ear plates 111 protruding outwards, and the adjustable height support legs 130 are disposed on the ear plates 111. In this embodiment, the number of ear plates 111 and the number of adjustable height support legs 130 can be equal, and the positions of the plurality of ear plates 111 correspond to the positions of the plurality of adjustable height support legs 130 respectively. For example, when the number of adjustable height support legs 130 is even, the number of ear plates 111 is also even, and the even number of ear plates 111 also have a front-to-back symmetrical structure with respect to the center plane of symmetry of the rectangular plate.

[0045] For example, the adjustable height support 130 is an anchor bolt, and the ear plate 111 has a threaded hole, in which the anchor bolt is disposed. In this embodiment, the levelness of the support platform 110 can be adjusted by means of the anchor bolt. It is understood that the type of adjustable height support 130 listed in this embodiment is only a few examples, and in other embodiments, other components besides anchor bolts can be used to adjust the levelness of the support platform 110.

[0046] In some specific embodiments of this utility model, the support platform 110 is rectangular in shape, with four ear plates 111 and four adjustable height supports 130, which are respectively located at the four corners of the rectangular platform. Figure 1 and Figure 3 As shown, the support platform 110 has two ear plates 111 on its front and rear sides, and there is a distance between the two ear plates 111 on each side. That is, the two ear plates 111 on each side are close to the left and right ends of the support platform 110. At this time, four adjustable height support feet 130 are respectively set on the four ear plates 111, that is, the four adjustable height support feet 130 are used to adjust the height of the four corners of the support platform 110. It is understood that setting the number of adjustable height support legs 130 to four in this embodiment is only an example. For example, when the shape of the support platform 110 is rectangular, the number of adjustable height support legs 130 can also be two or six. When the number of adjustable height support legs 130 is two, the front and rear sides of the support platform 110 are respectively provided with an ear plate 111, and the ear plates 111 on each side are located close to the end. When the number of adjustable height support legs 130 is six, the front and rear sides of the support platform 110 can be provided with three ear plates 111, and the three ear plates 111 on each side are spaced apart by a certain distance. In addition to the above, the number of adjustable height support legs 130 can also be an odd number. In addition, the shape of the support platform 110 can also be triangular, in which case the number of adjustable height support legs 130 can specifically be three, and the three adjustable height support legs 130 can also be respectively set at the three corners of the triangular support platform 110.

[0047] In one embodiment, the mobile platform further includes a level, which is disposed on the support platform 110. The level is used to monitor the levelness of the support platform 110, and can be specifically positioned on the top or side of the support platform 110. Figure 2As shown, the level may include a first level 141 and a second level 142. The first level 141 is arranged along the length direction of the rectangular platform, and the second level 142 is arranged along the width direction of the rectangular platform. In this embodiment, both the first level 141 and the second level 142 are arranged on the top of the support platform 110, with the first level 141 located near the front side of the rectangular support platform 110 and the second level 142 located near the right side of the rectangular support platform 110. The first level 141 is located in the middle part of the length direction of the support platform 110, while the second level 142 is located in the middle part of the width direction of the support platform 110.

[0048] In some embodiments of this utility model, the mobile platform includes a trolley handle 150, which is disposed on the support platform 110, and the trolley handle 150 is located on the side of the vacuum pump 200 away from the electrical distribution box 300. Figure 4 and Figure 5 The trolley handle 150 is specifically located on the left side of the vacuum pump 200, and the electrical control box 300 is specifically located on the right side of the vacuum pump 200.

[0049] Furthermore, the mobile vacuum pump platform includes a power distribution box bracket 400, the bottom end of which is fixed to the support platform 110, and the power distribution box 300 is mounted on the power distribution box bracket 400. In this embodiment, the power distribution box bracket 400 and the support platform 110 can be an integral structure, or they can be connected by a detachable connection; similarly, the power distribution box 300 and the power distribution box bracket 400 can be an integral structure, or they can be connected by a detachable connection.

[0050] In addition to the above, the vacuum pump 200 may specifically be a VDN602 vacuum pump; it is understood that limiting the vacuum pump 200 to a VDN602 vacuum pump in this embodiment is only an example, and in some other embodiments, other types of vacuum pumps 200 besides the VDN602 vacuum pump may be used. Furthermore, the power input terminal of the distribution box 300 has a quick-connect connector, which is used to connect with the quick-connect connector of the heat pump system; in this embodiment, setting the connection between the distribution box 300 and the heat pump system as a quick-plug connection improves the convenience of connection between the mobile vacuum pump platform and the heat pump system, thereby also improving the vacuum recovery efficiency of the heat pump system.

[0051] The mobile vacuum pump platform disclosed in the above embodiments can be quickly moved to the working area after the heat pump is overhauled, and can be quickly connected to the heat pump system, thereby realizing the rapid restoration of the vacuum degree of the heat pump system, reducing the degree of oxidation and corrosion of the heat exchange tubes, and also quickly reducing the dissolved oxygen in the heat pump water tank, ensuring the stable operation of the heat pump.

[0052] In this invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, and / or combined with or in place of features of other embodiments.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of this utility model.
