Description

Technical Field

[0001] The utility model relates to the technical field of parts of amusement facilities, in particular to a spray pump flow guiding and anti-rotation structure. Background Art

[0002] Amusement facilities refer to carriers used for business purposes, operating in a closed area and carrying tourists for amusement. A motorboat is a common amusement facility for water play;

[0003] A spray pump is a fluid dynamic pump, which is an indispensable part of a motorboat. It is installed at the bottom of the motorboat and used to spray water flow. By the acting force of the water flow, power is provided for the motorboat. In the existing spray pump structure, since the spray pump drives the water flow to spray by the rotation of the impeller, the sprayed water flow will rotate along with the rotation of the impeller and finally be sprayed out from the tail of the spray pump. This results in a more dispersed water flow force sprayed by the spray pump, thus reducing the efficiency of the spray pump. At the same time, the rotating water flow will generate a reverse torque on the impeller, reducing the service life of the impeller. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects in the prior art that since the spray pump drives the water flow to spray by the rotation of the impeller, the sprayed water flow will rotate along with the rotation of the impeller and finally be sprayed out from the tail of the spray pump, resulting in a more dispersed water flow force sprayed by the spray pump, thus reducing the efficiency of the spray pump. At the same time, the rotating water flow will generate a reverse torque on the impeller, reducing the service life of the impeller. A spray pump flow guiding and anti-rotation structure is provided. The impeller shaft bracket of the spray pump is connected to the pump body shell through a flow guiding stator. Under the action of the flow guiding stator, the rotation of the water flow output by the impeller can be eliminated, thus eliminating the reverse torque of the impeller, increasing the service life of the device, improving the efficiency of the spray pump at the same time, and through the structural design of the flow guiding stator, making the anti-rotation effect of the flow guiding stator more excellent, and not causing the water flow to be blocked too much due to the too large rotation direction of the flow guiding stator, which in turn affects the efficiency of the spray pump.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The utility model discloses a spray pump diversion and anti-rotation structure, which includes a spray pump main body. The spray pump main body adopts a modular assembly structure. The spray pump main body includes a spray pump base, a nozzle and a steering nozzle. Among them, an impeller is detachably installed in the spray pump base. One end of the spray pump base is welded or integrally formed with a first connecting plate. One end of the nozzle is welded or integrally formed with a connecting ring. The connecting ring is fixedly connected with the first connecting plate through a plurality of bolts. The steering nozzle is movably installed at the tail of the nozzle, and the steering nozzle can adjust the angle by rotation. Such a structural setting makes the whole spray pump main body a modular assembly structure. Therefore, when each structure is damaged, the damaged part can be disassembled and replaced separately. The spray pump base includes a pump body shell and an impeller shaft bracket. Among them, the impeller shaft bracket is connected with the pump body shell through a diversion stator. The shaft of the impeller is installed on the impeller shaft bracket. Under the action of the diversion stator, the rotation of the water flow output by the impeller can be eliminated. In this way, the reverse torque of the impeller can be eliminated, the service life of the device can be increased, and the efficiency of the spray pump can be improved at the same time.

[0007] Preferably, the other end of the spray pump base is welded or integrally formed with a second connecting plate. The second connecting plate is fixedly installed with an impeller jacket through bolts. The impeller jacket wraps the impeller inside. The impeller jacket and the impeller with such a structure can be replaced with different diameters and can be modularly replaced as needed. The nozzle and the steering nozzle can also be selected with different outlet diameters as needed to match different power requirements.

[0008] Preferably, both the nozzle and the steering nozzle adopt a horn-shaped structure in which the diameter gradually decreases from the water inlet end to the water spray end along the water flow spraying direction, and the waist positions of the nozzle and the steering nozzle have streamline arcs. Such a structural setting makes the water flow guiding ability of the spray pump stronger, and the horn-shaped structure can enhance the intensity of water flow spraying, thereby enhancing the power intensity.

[0009] Preferably, a plurality of the diversion stators are provided. The plurality of diversion stators are distributed in an annular array. The diversion stator has a rotation direction, and the rotation direction of the diversion stator is opposite to the rotation direction of the impeller. There is an included angle ∠α between the water flow direction in the pump body shell and the rotation direction of the diversion stator. The value range of ∠α is 15°-30°. Such a structural setting has a more excellent anti-rotation effect of the diversion stator, and will not cause excessive water flow obstruction due to the too large rotation direction of the diversion stator, which will instead affect the efficiency of the spray pump.

[0010] Preferably, a reinforcing rib plate is provided at the connection between the second connecting plate and the pump body shell. The reinforcing rib plate adopts a triangular structure. Such a structural setting makes the pump body shell and the second connecting plate have higher strength and better stability.

[0011] Preferably, two connecting caps are symmetrically arranged at the side position of one end of the nozzle. Two connecting ear pieces adapted to the connecting caps are arranged at the side position of one end of the deflecting nozzle. The deflecting nozzle is rotationally sleeved on the nozzle through the connecting ear pieces and the connecting caps, so that the deflecting nozzle can rotate and adjust the angle with the connecting line of the two connecting caps as the axis, change the angle of the deflecting nozzle, and thus change the spraying angle of the water flow to achieve the effect of adjusting the deflection.

[0012] Preferably, a plurality of auxiliary support connecting pieces are arranged on the side of the nozzle. They are used to connect with the hull, and the plurality of auxiliary support connecting pieces are connected to each other to form a triangular structure, which can greatly increase the stability and strength of the nozzle during use.

[0013] Preferably, an adjusting control ear piece is arranged on the outer edge of the end of the deflecting nozzle close to the nozzle. It is used to connect with the control pull rod of the hull to pull and adjust the orientation of the deflecting nozzle, thereby changing the spraying angle of the water flow.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The impeller shaft bracket of the spray pump is connected with the pump body shell through a guide stator. Under the action of the guide stator, the rotation of the water flow output by the impeller can be eliminated, so that the reverse torque of the impeller can be eliminated, the service life of the device can be increased, and the efficiency of the spray pump can be improved at the same time. And through the structural design of the guide stator, the effect of the guide stator on eliminating rotation is more excellent, and the water flow will not be blocked too much due to the excessive rotation direction of the guide stator, which will instead affect the efficiency of the spray pump;

[0016] The whole spray pump body is a modular assembly structure. Therefore, when each structure is damaged, the damaged part can be disassembled and replaced separately, and the impeller outer sleeve and the impeller can be replaced with different diameters and can be modularly replaced as needed. The nozzle and the deflecting nozzle can also be selected with different outlet diameters as needed to match different power requirements. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] The following further describes the detailed implementation manners of a spray pump flow guide and anti-rotation structure of the present utility model in conjunction with the attached Figure 1 - attached Figure 7 , overcoming the defects in the prior art that since the spray pump drives the water flow to spray by the rotation of the impeller, the sprayed water flow will rotate following the rotation of the impeller and finally spray out from the tail of the spray pump, resulting in a relatively dispersed water flow force sprayed by the spray pump, thus reducing the efficiency of the spray pump. At the same time, the rotating water flow will generate a reverse torque on the impeller, resulting in a reduced service life of the impeller. The impeller shaft bracket of the spray pump is connected to the pump body housing through a guide stator. Under the action of the guide stator, the rotation of the water flow output by the impeller can be eliminated, so that the reverse torque of the impeller can be eliminated, the service life of the device can be increased, and at the same time, the efficiency of the spray pump can be improved. And through the structural design of the guide stator, the anti-rotation effect of the guide stator is more excellent, and the water flow will not be blocked too much due to the too large rotation direction of the guide stator, which will instead affect the efficiency of the spray pump. A spray pump flow guide and anti-rotation structure of the present utility model is not limited to the description of the following embodiments.
