a curved baffle shell is arranged in the vertical cavity, the right end of the curved baffle shell is in a wide-mouth shape, and an impeller is arranged at the wide-mouth position;
the impeller is installed at the end head of the output shaft, the output shaft is horizontally arranged and is connected with the motor in a driving way, the output shafts positioned in the vertical cavity and the horizontal cavity are provided with central shaft holes, and the output shaft positioned in the horizontal cavity is provided with a large waist-shaped through hole;
water in the curved baffle shell enters the horizontal cavity through the central shaft hole and the large waist-shaped through hole and then flows into the vertical cavity, and the water is outside the curved baffle shell.
Furthermore, a small gap is arranged between the impeller and the wide mouth of the curved baffle shell, and the distance of the small gap is one tenth to one fifth of the diameter of the central shaft hole.
Furthermore, a baffle plate for preventing a large amount of water from directly flowing downwards is arranged at the lower part of the curve removing baffle shell in the vertical cavity.
Preferably, the vertical cavity, the horizontal cavity and the motor are supported and fixed on the bottom plate.
Preferably, the output shaft is installed in a matched mode with the horizontal cavity in a sealing mode through a bearing, and the motor is connected with the output shaft through a coupler.
The utility model has the advantages of it is following: (1) in the scheme, the impeller mainly forms negative pressure, and the output shaft is provided with the central shaft hole and the large waist-shaped through hole, so that water flows from the central shaft hole to the large waist-shaped through hole, the impeller cannot block the flow of the water too much, and the water flow is improved;
(2) the wide-mouth structure of the curved baffle shell and the small gap between the wide-mouth structure and the impeller are arranged, so that excessive water is prevented from flowing from the direction of the impeller, and the influence of impeller blocking is reduced;
(3) the baffle is arranged to enable more water to be positioned at the upper part of the vertical cavity, so that the water can be drained from the water outlet barrel at the top.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1, a novel structure of a water pump comprises a vertical cavity 1, a horizontal cavity 2 and a motor 3. A horizontal cavity 2 which is connected and communicated is arranged at the right side wall of the vertical cavity 1, an output shaft 7 in the horizontal direction is arranged in the horizontal cavity 2, and the output shaft 7 penetrates through the horizontal cavity 2 and is connected with a motor 3 in a driving mode. The vertical cavity 1, the horizontal cavity 2 and the motor 3 are all fixed on the bottom plate 4 through support.
In the scheme, a water inlet barrel 5 is arranged above the left side wall of the vertical cavity 1, and a water outlet barrel 6 is arranged at the top of the water inlet barrel; a curved baffle shell 8 is arranged in the inner part of the device, the right end of the curved baffle shell 8 is in a wide mouth shape, and the wide mouth is also in a neck shape. The wide mouth is provided with an impeller 10, and a small gap is arranged between the impeller 10 and the wide mouth of the curved retaining shell 8 so as to reduce the water flow between the impeller 10 and the curved retaining shell 8.
The main structure of flow direction of rivers does in this scheme: the impeller 10 is arranged at the end of the output shaft 7; the output shaft 7 positioned in the vertical cavity 1 and the horizontal cavity 2 is provided with a central shaft hole 701, and the central through hole 701 reaches the left end surface of the output shaft 7 and is communicated with the inside of the curved blocking shell 8; and a large waist-shaped through hole 702 is arranged on the output shaft 7 positioned in the horizontal cavity 2.
