[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, in the horizontal water pump support, the water pump includes a volute 1. A drain ring 1a is vertically formed on the bottom wall of the volute 1, and the inner hole of the drain ring 1a communicates with the inner cavity of the volute 1. The support includes a pump cover 2 vertically fixed to the rear side of the volute 1 and a sleeve 3 horizontally positioned behind the pump cover 2. A base plate 4 is horizontally positioned below the sleeve 3, and the base plate 4 supports the sleeve 3 via a connecting bracket 5. The bottom of the pump cover 2 is connected to the front end of the base plate 4 via a connecting plate 6. In the actual product, the top of the pump cover 2 is connected to the top of the sleeve 3 via an arc-shaped strip to enhance the overall stability of the support structure.

[0027] like Figures 2 to 4As shown, the bottom plate 4 is horizontally profiled with a support plate 4a at the front end, and the support plate 4a is directly below the volute 1. The support plate 4a is preferably flat. A connecting sleeve 7 is vertically arranged between the support plate 4a and the volute 1, the upper end of the connecting sleeve 7 is sleeved outside the drain ring 1a and is sealingly and fixedly connected with the drain ring 1a. The lower end of the connecting sleeve 7 is fixedly pressed on the support plate 4a. A strip-shaped flow channel 4b is formed in the support plate 4a, the inlet of the strip-shaped flow channel 4b is arranged on the top wall of the support plate 4a and is communicated with the connecting sleeve 7, and the outlet of the strip-shaped flow channel 4b is arranged on the side wall of the support plate 4a. A plugging member is detachably fixed at the outlet of the strip-shaped flow channel 4b to close the outlet of the strip-shaped flow channel 4b.

[0028] The volute 1 is fixedly connected with the support plate 4a through the connecting sleeve 7, and under the premise of enhancing the support effect of the support frame on the volute 1, the connecting sleeve 7 is matched with the strip-shaped flow channel 4b to change the drainage direction of the volute 1 from vertical to horizontal, and the outlet of the strip-shaped flow channel 4b is arranged on the side of the support plate 4a without obstruction, so that the plugging member can be effectively and conveniently taken out for drainage operation, and the use is easy and convenient.

Further, the inner wall of the upper end of the connecting sleeve 7 is provided with a ring-shaped support step 7a, the support step 7a is internally provided with a ring-shaped rubber pad two 9, and the two end surfaces of the rubber pad two 9 are tightly pressed on the bottom wall of the drain ring 1a and the bottom wall of the support step 7a. Under the action of the rubber pad two 9, reliable sealing can be ensured between the connecting sleeve 7 and the drain ring 1a after the position adjustment.

[0033] The connecting sleeve 7 is welded to the support plate 4a, and further, an annular groove is formed in the bottom wall of the connecting sleeve 7, and the annular groove is coaxially arranged with the connecting sleeve 7. A rubber pad 10 is arranged in the annular groove, and the two end faces of the rubber pad 10 are tightly pressed against the bottom wall of the annular groove and the top wall of the support plate 4a respectively, so as to enhance the sealing performance between the connecting sleeve 7 and the support plate 4a and improve the working stability.
