Description

Technical Field

[0001] The utility model relates to the technical field of external-mounted spray pumps, in particular to a propeller of an external-mounted spray pump. Background Art

[0002] A propeller is a device that converts the engine's rotational power into propulsion by rotating blades in air or water. It can have two or more blades connected to a hub, with the rearward-facing surface of the blades forming a helical surface or something resembling a helical surface. There are many different types of propellers, and they are used in a wide range of applications, including propellers for aircraft and ships.

[0003] The existing external spray pump has certain problems when in use. The water spray pump on the boat is similar to a propeller, which uses the water spray pump to drive the impeller to rotate and spray water backwards for rapid forward movement. After long-term use of the impeller, a large amount of seaweed and pollutants will often adhere to the surface. If it is not cleaned in time, it is easy to cause the impeller to be entangled and necrotic, affecting the use of the boat. It is also relatively troublesome to repair. In addition, the existing propeller boats are not safe when in use and are easy to injure the staff. In response to the above problems, an improvement and upgrade of the propeller of the external spray pump is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a propeller for an external jet pump to solve the problems raised in the above background technology.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] A propeller for an external jet pump is designed, comprising a propulsion water pipe, an external mounting bracket being fixedly provided on the outer wall of the propulsion water pipe, and one end of the propulsion water pipe being fixedly connected to one end of a main sleeve, an impeller being rotatably installed inside the main sleeve, a first mounting bracket being provided at the other end of the main sleeve, a disassembly assembly being provided on the outside of the first mounting bracket, a second mounting bracket being provided on one side of the disassembly assembly, and an electric protective cover being provided on the outer wall of the second mounting bracket.

[0007] Furthermore, a limit rod is fixedly provided on the upper end surface of the main sleeve and one end of the limit rod is sleeved above the second mounting bracket. Six screws are provided on the outer wall of the first mounting bracket and the screws are rotatably installed on the outer wall of the main sleeve.

[0008] Furthermore, a filter is provided inside the first mounting frame and the filter is slidably engaged inside the first mounting frame, and the disassembly assembly includes a mounting plate, a engaging circular plate and a knob.

[0009] Furthermore, the mounting plate is fixedly mounted inside the first mounting frame, the clamping circular plate is fixedly mounted inside the second mounting frame, and a placement groove is provided inside the mounting plate.

[0010] Furthermore, a sealing ring is fixedly provided inside the placement groove and a sealing gasket is fitted on the outside of the sealing ring. One end of the clamping circular plate is clamped on the placement groove. There are two knobs and the knobs are fixedly connected to a threaded rod.

[0011] Furthermore, two thread grooves are symmetrically provided inside the installation plate, and threaded rods are provided in the threaded interior of the thread grooves, and one end of the threaded rods is clamped on the clamping circular plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a mounting plate, a clamping circular plate, a knob, a threaded rod, a sealing ring, a filter screen and other components. By rotating the two knobs, the threaded rod is driven to rotate away from the clamping circular plate, and then the clamping circular plate is moved away from the placement groove inside the mounting plate. A sealing ring and a sealing gasket are provided to facilitate relative sealing when the clamping circular plate is connected.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 4 As shown, the present embodiment provides a propeller for an external jet pump, comprising a propulsion water pipe 1, an external mounting bracket 8 fixedly provided on the outer wall of the propulsion water pipe 1, and one end of the propulsion water pipe 1 is fixedly connected to one end of a main sleeve 2, an impeller 9 is rotatably installed inside the main sleeve 2, a first mounting bracket 4 is provided at the other end of the main sleeve 2, and a disassembly component 5 is provided on the outside of the first mounting bracket 4, a second mounting bracket 6 is provided on one side of the disassembly component 5, and an electric protective cover 7 is provided on the outer wall of the second mounting bracket 6.

[0023] Preferably, a limit rod 3 is fixedly provided on the upper end surface of the main sleeve 2 and one end of the limit rod 3 is sleeved on the second mounting bracket 6, six screws 41 are provided on the outer wall of the first mounting bracket 4 and the screws 41 are rotatably installed on the outer wall of the main sleeve 2, a filter screen 42 is provided inside the first mounting bracket 4 and the filter screen 42 is slidably clamped inside the first mounting bracket 4, and the disassembly assembly 5 includes a mounting plate 51, a clamping circular plate 52 and a knob 53. By setting the limit rod 3, the position of the second mounting bracket 6 is limited to prevent it from slipping.

[0024] Preferably, the mounting disk 51 is fixedly mounted inside the first mounting frame 4, the clamping circular plate 52 is fixedly mounted inside the second mounting frame 6, a placement groove 55 is provided inside the mounting disk 51, a sealing ring 56 is fixedly provided inside the placement groove 55, and a sealing gasket 57 is fitted and connected to the outside of the sealing ring 56, one end of the clamping circular plate 52 is clamped on the placement groove 55, there are two knobs 53 and the knob 53 is fixedly connected to the threaded rod 54, two threaded grooves 58 are symmetrically provided inside the mounting disk 51, the threaded grooves 58 are internally threaded with a threaded rod 54 and one end of the threaded rod 54 is clamped on the clamping circular plate 52, the threaded rod 54 is driven to rotate away from the clamping circular plate 52 by rotating the two knobs 53, and then the clamping circular plate 52 is moved away from the placement groove 55 inside the mounting disk 51, and the sealing ring 56 and the sealing gasket 57 are provided to facilitate relative sealing when the clamping circular plate 52 is connected.

[0025] The principle and process of use of the present invention are as follows: by installing the external bracket 8 on the boat, connecting the external power supply, driving the water jet pump to drive the impeller 9 in the main sleeve 2 to rotate, and then by pushing the water source from the propulsion water pipe 1 along the main sleeve 2 from the second mounting bracket 6 backward, the boat is driven to travel quickly. When the impeller 9 is used for a long time, a large amount of seaweed and pollutants will adhere to the surface. At this time, by rotating the two knobs 53, the threaded rod 54 is driven to rotate away from the clamping circular plate 52, and then the clamping circular plate 52 is moved away from the placement groove 55 inside the mounting plate 51, and a sealing ring 56 and a sealing gasket 57 are provided to facilitate relative sealing when the clamping circular plate 52 is connected. Then the second mounting bracket 6 is disassembled, and then the internal filter screen 42 of the first mounting bracket 4 is moved out to intercept and block the pollutants. In this way, the staff can easily clean the impeller 9 through the first mounting bracket 4 to prevent seaweed and pollutants from causing the impeller 9 to be entangled and affecting use. A water jet pump is provided instead of the propeller, which is relatively safe and convenient to use.
