The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The utility model embodiment provides a circulation pump which is easy to install, such as Figure 1-Figure 5 As shown, the circulating pump that is easy to install includes:

[0031] A driving motor 110 and a circulating pump body 120;

[0032] A floating plate 200 and a base 300, wherein the floating plate 200 slides on the base 300, and the drive motor 110 and the circulating pump body 120 are fixed to the end surface of the floating plate 200 away from the base 300 by bolts;

[0033] An inlet compensator 500 is provided at the water inlet of the circulation pump body 120, and an outlet compensator 400 is provided at the water outlet of the circulation pump body 120; the driving motor 110 and the circulation pump body 120 slide and move along the axial direction of the inlet compensator 500 with the help of the floating plate 200, so as to help the inlet compensator 500 align with the water outlet pipe located above the circulation pump body 120, and the inlet compensator 500 compensates for the height difference between the water outlet of the circulation pump body 120 and the docking water outlet pipe by lifting and extending, and the inlet compensator 500 compensates for the distance difference caused by the sliding movement of the floating plate 200;

[0034] In this embodiment, the driving motor 110 and the circulating pump body 120 are both existing mature technologies, and the outlet compensator 400 and the inlet compensator 500 are fixedly connected to the circulating pump body 120 by welding, and the base 300 is generally fixed on the loading platform. When the circulating pump is installed, it is found that the liquid inlet and the liquid outlet are misaligned. By sliding between the floating plate 200 and the base 300, the inlet compensator 500 is calibrated and aligned with the water outlet pipe located above the circulating pump body 120, and the inlet compensator 500 and the outlet compensator 400 are used to compensate for the gap that still exists after the floating plate 200 and the base 300 are slid and adjusted, thereby reducing the connection difficulty caused by the misalignment problem during the pipe docking process and improving the convenience of installing the circulating pump;

[0035] As a preferred implementation in this embodiment, the end surface of the floating plate 200 away from the driving motor 110 and the circulating pump body 120 is provided with a guide slider 210 and a driving slider 220;

[0036] The end surface of the base 300 close to the floating plate 200 is provided with a guide slot 310 adapted to the guide slider 210 and a driving slot 320 adapted to the driving slider 220. The guide slider 210 slides in the guide slot 310, and the driving slot 320 is further provided with a driving screw 330. The driving screw 330 penetrates the driving slider 220 that slides in the driving slot 320.

[0037] In this embodiment, the driving screw 330 extends from one side of the base 300 into the driving slide groove 320, and the driving screw 330 is assembled through bearings arranged at both ends of the driving slide groove 320. The driving screw 330 can rotate under the bearing structure, and the driving slider 220 is provided with a screw hole matching the driving screw 330. When the driving screw 330 rotates, the driving slider 220 will move axially along the driving screw 330 under the limit of the driving slide groove 320. The structural principle here is the same as the principle of the screw transmission technology in the prior art. The driving screw 330 uses self-rotation to complete the position movement adjustment of the driving slider 220.

[0038] As a preferred implementation in this embodiment, the outlet compensator 400 includes a base pipe 410, a telescopic pipe 420 and a sliding pipe 430; the sliding pipe 430 extends from one end of the base pipe 410 into the interior of the base pipe 410, one end of the telescopic pipe 420 is connected to the base pipe 410, and the other end of the telescopic pipe 420 is connected to one end of the sliding pipe 430 extending into the base pipe 410;

[0039] In this embodiment, both ends of the base pipe 410 are provided with limiting rings, wherein one end of the base pipe 410 is welded or assembled to the water outlet of the circulation pump body 120 through a flange structure, and the limiting ring on the side of the base pipe 410 close to the circulation pump body 120 mainly provides a connection end surface for the telescopic pipe 420, while the limiting ring on the other side prevents the sliding pipe 430 from slipping off the base pipe 410;

[0040] The sliding pipe 430 includes a limiting connection block 431, a pipe body 432 and a connection flange 433. The limiting connection block 431 and the connection flange 433 are respectively arranged at two ends of the pipe body 432. The limiting connection block 431 slides on the inner wall of the base pipe 410, and the limiting ring arranged on the base pipe 410 prevents the limiting connection block 431 from sliding out of the inner wall of the base pipe 410. The connection flange 433 is located outside the base pipe 410.

[0041] The telescopic tube 420 is composed of a telescopic section and connecting plates arranged at both ends of the telescopic section. The telescopic section is made of a stainless steel telescopic tube. The connecting plate is a ring-shaped structure and is mainly used for connecting the telescopic tube 420. In this application, the liquid sent out of the water outlet will first pass through the limit ring and then enter the inside of the telescopic tube 420, and then enter the sliding pipe 430, and be transported outward by the sliding pipe 430. Here, the telescopic tube 420 has a deformation space, which allows the sliding pipe 430 to extend and change its length, thereby meeting the needs of docking connection.

[0042] The structural principle of the inlet compensator 500 is the same as that of the outlet compensator 400, and the sliding end of the inlet compensator 500 is away from the circulating pump body 120;
