Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a novel water pump guide vane impeller structure. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. The impeller refers to the disk with moving blades, which is a component of the impulse turbine rotor. It can also refer to the general term for the disk and the rotating blades installed on it. Impellers can be classified according to their shape and opening and closing conditions.

[0003] When conveying liquid, the impeller of a water pump will collide with solid impurities in the liquid, thereby causing damage to a single blade. In the prior art, the impeller disc and blades of the water pump impeller are usually cast and welded together, resulting in an inability to replace or repair a single blade. Directly replacing the entire impeller will cause a waste of resources and increase maintenance costs, while affecting the working efficiency of the water pump and making it inconvenient to use. In order to solve the above-mentioned problems, the utility model provides a novel water pump guide vane impeller structure. Utility Model Content

[0006] The locking structure comprises a first bolt threadedly mounted on the wheel disc, one end of the first bolt is sleeved with an arc-shaped soft plate, one end of the first bolt passes through the wheel disc and the mounting shaft, and one end of the first bolt is threadedly mounted with a first nut;

[0007] The impeller structure comprises two impellers threadedly mounted on the mounting shaft, the two impellers have the same structure, and a plurality of blades are detachably mounted on both impellers via a clamping structure.

[0008] Furthermore, the clamping structure includes a plurality of T-slots formed on the mounting shaft, and one end of each of the plurality of blades is T-shaped and clamped in the plurality of T-slots.

[0009] Furthermore, two gaskets are symmetrically distributed and threadedly installed on the installation shaft, the two impellers are located between the two gaskets, and a locking piece is also installed between the two gaskets.

[0010] Furthermore, the locking member includes second bolts threadedly installed between the two gaskets in a circular array, and the second bolts penetrate the two gaskets and the two impellers, and a second nut is threadedly installed at one end of the second bolt.

[0011] Compared with the prior art, the utility model has the following beneficial effects: one end of the blade can be clamped in the T-slot provided on the installation shaft and locked by two gaskets, which can prevent the blade from slipping out of the T-slot, and at the same time the locking piece can strengthen the fixation of the gasket to the blade, which is easy to operate, allowing the user to replace or repair a single blade, reducing the user's workload, and has certain practicality.

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0017] like Figure 1-3 As shown, a novel water pump guide vane impeller structure proposed in one embodiment of the utility model includes a wheel disc 1, characterized in that: a plurality of threaded holes 2 are opened on the wheel disc 1, a mounting shaft 4 is detachably mounted on the wheel disc 1 through a locking structure 3, and an impeller structure 5 is arranged on the mounting shaft 4. When in use, the wheel disc 1 is firstly mounted in the water pump through the threaded holes 2.

[0018] like Figure 1 and Figure 3As shown, in order to achieve the installation of the mounting shaft 4, the locking structure 3 includes a first bolt 31 threadedly mounted on the wheel disc 1, one end of the first bolt 31 is sleeved with an arc-shaped soft plate 32, and one end of the first bolt 31 passes through the wheel disc 1 and the mounting shaft 4, and one end of the first bolt 31 is threadedly mounted with a first nut 33, the mounting shaft 4 is inserted into the wheel disc 1 and the first bolt 31 is rotated until the arc-shaped soft plate 32 contacts the wheel disc 1, and finally the first nut 33 is installed on the first bolt 31 and tightened, thereby fixing the mounting shaft 4 on the wheel disc 1.

[0019] like Figure 1 and Figure 2 As shown, in order to achieve the installation of the blades 52, the impeller structure 5 includes two impellers 51 threadedly mounted on the mounting shaft 4, the two impellers 51 have the same structure, and both impellers 51 are detachably mounted with multiple blades 52 through a clamping structure 6, the clamping structure 6 includes multiple T-slots 61 opened on the mounting shaft 4, one end of the multiple blades 52 is T-shaped and clamped in the multiple T-slots 61, first install the two impellers 51 on the mounting shaft 4, and then insert the T-shaped end of the blade 52 into the T-slot 61, so that the blade 52 can be installed, and the operation is simple.

[0020] like Figure 3 As shown, in order to fix the blades 52, two gaskets 7 are symmetrically distributed and threadedly installed on the installation shaft 4, the two impellers 51 are located between the two gaskets 7, and a locking piece 8 is also installed between the two gaskets 7. After the blades 52 are installed, the two gaskets 7 are respectively installed on the left and right sides of the two impellers 51, so that one side of the gasket 7 is in close contact with the impeller 51, respectively, to prevent the blades 52 from slipping out of the T-slot 61.

[0021] like Figure 3 As shown, in order to achieve the fixation of the two gaskets 7, the locking member 8 includes second bolts 81 threadedly installed between the two gaskets 7 in a circular array, and the second bolts 81 pass through the two gaskets 7 and the two impellers 51, and one end of the second bolt 81 is threadedly installed with a second nut 82. The second bolt 81 is directly threadedly installed between the two gaskets 7, and then the second nut 82 is installed on the second bolt 81 and tightened, thereby achieving the fixation of the two gaskets 7 and strengthening the fixation of the blades 52.

At the same time, two impellers 51, multiple blades 52 and two gaskets 7 are installed on the mounting shaft 4 in sequence and locked using the locking member 8. When one of the blades 52 is damaged and needs to be repaired or replaced, first rotate the second nut 82 to remove it from the second bolt 81, then rotate the second bolt 81 until the second bolt 81 no longer fixes the two gaskets 7, and then rotate the two gaskets 7 and remove them from the mounting shaft 4, thereby releasing the fixation of the blade 52. At this time, the user can pull the damaged blade 52 out of the T-slot 61 and install a new blade 52 in the T-slot 61, and finally reinstall the gasket 7, the second bolt 81 and the second nut 82 on the mounting shaft 4.

[0023] Finally, the most important contribution of the present invention is that one end of the blade 52 can be snapped into the T-slot 61 provided on the mounting shaft 4 and locked by two gaskets 7, which can prevent the blade 52 from slipping out of the T-slot 61. At the same time, the locking member 8 can strengthen the fixation of the gasket 7 to the blade 52. The operation is convenient, so that the user can replace or repair a single blade 52, which reduces the user's workload and has certain practicality.
