Technical Field

The utility model belongs to the technical field of the water pump, concretely relates to dive axial-flow pump.

Background

The ski-type axial-flow pump is a pump which can make liquid be transferred along the axial direction and submerged in water to work by means of acting force produced by blade of rotating impeller, and is mainly formed from dry motor, hydraulic component and two or three mechanical seals.

The submersible axial-flow pumps are submerged to work, so sundries such as aquatic weeds and the like are easy to be sucked into the pump body, the blades are wound, generally, a mesh plate for filtering the aquatic weeds and the sundries is arranged at the lower end of the pump body, in actual use, the sundries are easy to be adsorbed onto the mesh plate due to the suction force of the pump body, meshes are blocked, the internal pressure of the pump body is gradually increased, the service life of a motor is shortened, and the problems are required to be solved by targeted design.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a dive axial-flow pump comes into operation to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a dive axial-flow pump, includes the pump body, brush board, fixed mounting in the output motor of pump body upper end and rotate the pump shaft and the epaxial impeller seat of fixed mounting in pump with output motor, the lower extreme fixed mounting of pump shaft has the eccentric wheel, the spacing groove has been seted up at the middle part of brush board, the eccentric wheel rotates and sets up in the inside of spacing groove, the brush board passes through gag lever post and pump body sliding connection, the lower extreme welding of the pump body has the baffle, the inboard welding of the water inlet of seting up on the baffle has the otter board.

Preferably, the brush board is formed by laying bristles at the lower end of the plastic board, and the length of the bristles is larger than the distance between the brush board and the baffle.

Preferably, the bristles are made of steel wires or rayon wires.

Preferably, the two ends of the brush plate are provided with limiting holes, and the limiting rods penetrate through the limiting holes and are welded and fixed with the inner wall of the pump body.

Preferably, the limiting groove is a round-corner rectangular groove, and the outer side wall of the eccentric wheel is clamped by the limiting groove.

The utility model discloses a technological effect and advantage: this dive axial-flow pump drives the eccentric wheel through pump shaft work and rotates, through eccentric wheel and spacing groove cooperation for brush board horizontal reciprocating sliding clears up the otter board, when preventing debris to inhale in the pump body, avoids debris such as pasture and water to block up the otter board.

In the figure: 1. a pump body; 2. an output motor; 3. a pump shaft; 4. an impeller seat; 5. an eccentric wheel; 6. brushing the board; 7. a limiting groove; 8. a limiting rod; 9. a baffle plate; 10. a screen plate; 11. a limiting hole; 61. plastic board; 62. and (3) brush hairs.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a dive axial-flow pump as shown in fig. 1-3, including the pump body 1, brush 6 fixed mounting in the output motor 2 of the 1 upper end of the pump body and with output motor 2 rotate pump shaft 3 and fixed mounting in the epaxial impeller seat 4 of pump, the lower extreme fixed mounting of pump shaft 3 has eccentric wheel 5, spacing groove 7 has been seted up at the middle part of brush 6, eccentric wheel 5 rotates and sets up in the inside of spacing groove 7, brush 6 passes through gag lever post 8 and 1 sliding connection of the pump body, the lower extreme welding of the pump body 1 has baffle 9, the inboard welding of the water inlet of seting up on the baffle 9 has otter board 10. After the axial-flow pump starts, output motor 2 drives pump shaft 3 and rotates, and pump shaft 3 drives impeller seat 4 and rotates and draw water the operation, and inside the water inlet that rivers pass through baffle 9 entered into the pump body 1, pump shaft 3 drove eccentric wheel 5 simultaneously and rotates, extrudees between eccentric wheel 5's the lateral wall and the spacing groove 7 inner wall to drive brush 6 and brush and scrape the intraoral otter board 10 of inlet, avoid debris such as pasture and water to block up the mesh.

The brush plate 6 is formed by laying bristles 62 at the lower end of a plastic plate 61, and the length of the bristles 62 is larger than the distance between the brush plate 6 and the baffle plate 9, so that the bristles 62 at the lower end of the brush plate 6 can be fully contacted with the screen plate 10 on the baffle plate 9 to clean the screen plate 10.
