[0003] A jet pump is a type of fluid power pump, which is an indispensable part of a motorboat. It is installed at the bottom of the motorboat and used to eject water flow. Through the acting force of the water flow, it provides power for the motorboat. In the existing jet pump structures, most of them adopt an integrated installation structure. Therefore, when the jet pump structure is damaged, it is cumbersome to replace, and when replacing, the entire jet pump needs to be replaced, and the maintenance cost is relatively high. Therefore, it is difficult to meet people's needs. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the defect that in the existing jet pump structure, most of them adopt an integrated installation structure. Therefore, when the jet pump structure is damaged, it is cumbersome to replace, and when replacing, the entire jet pump needs to be replaced, and the maintenance cost is relatively high. The utility model provides a modular jet pump. The whole jet 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 steering nozzle can also be selected with different outlet diameters as needed to match different power requirements.

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

[0006] The utility model discloses a modular jet pump, which includes a jet pump body. The jet pump body adopts a modular assembly structure. The jet pump body includes a jet pump base, a nozzle and a steering nozzle. Among them, an impeller is detachably installed in the jet pump base. One end of the jet 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 jet pump body a modular assembly structure. Therefore, when each structure is damaged, the damaged part can be disassembled and replaced separately.

[0007] Preferably, a second connecting plate is welded or integrally formed at the other end of the spray pump base. The second connecting plate is fixedly installed with an impeller housing through bolts. The impeller housing wraps the impeller inside. The impeller housing and impeller of this structure 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.

[0008] Preferably, both the nozzle and the deflecting nozzle adopt a horn-shaped structure with a gradually decreasing diameter from the water inlet end to the water spraying end along the water flow spraying direction, and the waist positions of the nozzle and the deflecting 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, the spray pump base includes a pump body housing and an impeller shaft bracket. Among them, the impeller shaft bracket is connected to the pump body housing through a guide stator. The shaft of the impeller is installed on the impeller shaft bracket. Under the action of the guide stator, the rotation of the water flow output by the impeller can be eliminated.

There is an included angle ∠α between the water flow direction in the pump body housing and the rotation direction of the guide stator. The value range of ∠α is 15° - 30°. Such a structural setting has a more excellent effect of eliminating rotation by the guide stator and will not cause excessive water flow obstruction due to too large a rotation direction of the guide 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 housing. The reinforcing rib plate adopts a triangular structure. Such a structural setting makes the pump body housing and the second connecting plate have higher strength and better stability.

[0011] Preferably, two connecting caps are symmetrically arranged at one side position of the nozzle. Two connecting ear pieces adapted to the connecting caps are provided at one side position 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 connection 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 steering.

[0012] Preferably, a plurality of auxiliary support connecting pieces are provided 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. This can greatly increase the stability and strength of the nozzle during use.

[0013] Preferably, an adjustment control earpiece is provided on the outer edge of one end of the steering nozzle close to the nozzle. It is used to connect with the control pull rod of the hull and is used to pull and adjust the orientation of the steering nozzle, thereby changing the jet angle of the water flow.

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

[0015] The main body of the jet pump is an overall modular assembly structure. Therefore, when each structure is damaged, the damaged part can be disassembled and replaced separately. Moreover, the impeller outer sleeve and the impeller 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.

[0016] The impeller shaft bracket of the jet pump is connected to the pump body housing through a flow guide stator. Under the action of the flow guide 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 at the same time, the efficiency of the jet pump can be improved. And through the structural design of the flow guide stator, the effect of the flow guide stator in eliminating rotation is more excellent, and the water flow will not be blocked too much due to the excessive rotation direction of the flow guide stator, which will instead affect the efficiency of the jet pump.

Therefore, when the spray pump structure is damaged, it is cumbersome to replace, and when replacing, the entire spray pump needs to be replaced, and the maintenance cost is relatively high. The spray pump body is a modular assembly structure as a whole. Therefore, when each structure is damaged, the damaged part can be disassembled and replaced separately, and the impeller jacket and impeller can be replaced with different diameters, and can be modularly replaced as needed. The nozzles and steering nozzles can also be selected with different outlet diameters as needed to match different power requirements. The modular spray pump of the present invention is not limited to the description of the following embodiments.

[0026] Embodiment 1:

[0027] This embodiment provides a modular spray pump, as Figure 1-7 shown, including a spray pump body 1. The spray pump body 1 adopts a modular assembly structure. The spray pump body 1 includes a spray pump base 13, a nozzle 14 and a steering nozzle 15. Among them, an impeller 11 is detachably installed in the spray pump base 13. One end of the spray pump base 13 is welded or integrally formed with a first connecting plate 1332. One end of the nozzle 14 is welded or integrally formed with a connecting ring 143. The connecting ring 143 is fixedly connected to the first connecting plate 1332 through a plurality of bolts. The steering nozzle 15 is movably installed at the tail of the nozzle 14, and the steering nozzle 15 can adjust the angle by rotation.

[0028] By adopting the above technical solutions:

[0029] The spray pump body 1 is a modular assembly structure as a whole. Therefore, when each structure is damaged, the damaged part can be disassembled and replaced separately.

[0030] Embodiment 2

[0031] On the basis of Embodiment 1, in this embodiment, the other end of the spray pump base 13 is welded or integrally formed with a second connecting plate 1333. The second connecting plate 1333 is fixedly installed with an impeller jacket 12 through bolts. The impeller jacket 12 wraps the impeller 11 inside. The impeller jacket 12 and the impeller 11 with this structure can be replaced with different diameters and can be modularly replaced as needed. The nozzle 14 and the deflector nozzle 15 can also be selected with different outlet diameters as needed to match different power requirements.

[0032] Both the nozzle 14 and the deflector nozzle 15 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 spray direction, and the waist position of the nozzle 14 and the deflector nozzle 15 has a streamline arc. 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 injection, thereby enhancing the power intensity.

[0033] The spray pump base 13 includes a pump body housing 133 and an impeller shaft bracket 131. Among them, the impeller shaft bracket 131 is connected to the pump body housing 133 through a flow guiding stator 132, and the shaft of the impeller 11 is installed on the impeller shaft bracket 131;

[0034] Furthermore, a plurality of flow guiding stators 132 are provided in total. The plurality of flow guiding stators 132 are distributed in a circular array. The flow guiding stator 132 has a rotation direction, and the rotation direction of the flow guiding stator 132 is opposite to the rotation direction of the impeller 11. There is an included angle ∠α between the water flow direction in the pump body housing 133 and the rotation direction of the flow guiding stator 132. The value range of ∠α is 15° - 30°.

[0035] Reinforcing rib plates 1331 are provided at the connection between the second connecting plate 1333 and the pump body housing 133. The reinforcing rib plates 1331 adopt a triangular structure. Such a structural setting makes the pump body housing 133 and the second connecting plate 1333 have higher strength and better stability.

[0036] By adopting the above technical solutions:

[0037] Under the action of the flow guiding stator 132, the rotation of the water flow output by the impeller 11 can be eliminated, which can eliminate the reverse torque of the impeller, increase the service life of the device, and at the same time improve the efficiency of the spray pump. And through the design of the angle of the flow guiding stator 132, its anti-rotation effect is more excellent, and it will not cause excessive water flow obstruction due to the too large rotation direction of the flow guiding stator 132, which in turn affects the efficiency of the spray pump.

[0042] By adopting the above technical solutions:

[0043] The deflecting nozzle 15 can rotate and adjust the angle with the connection line of the two connecting caps 142 as the axis, change the angle of the deflecting nozzle 15, and thus change the jet angle of the water flow to achieve the effect of adjusting the steering.
