Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, in particular to an impeller that is wear-resistant and has a long service life. Background Art

[0002] A water pump is a common mechanical equipment. Its main function is to extract water from one source through the water pump and then transport it to another place to achieve the purpose of farmland irrigation and fire extinguishing. It plays a very important role in daily life.

[0003] The main function of the water pump impeller is to transfer the mechanical energy of the prime mover directly to the liquid to increase the static pressure energy and kinetic energy of the liquid, mainly increasing the static pressure energy. When the impeller is driven to rotate by the motor, a vacuum will be generated in the middle of the impeller, and water will flow into the vacuum (on the surface, the impeller continuously sucks in water), and then the water is discharged through the high-speed rotating impeller, which plays a role in pushing the water.

[0004] In the current existing technology, when a water pump extracts water from a river through an impeller, due to the poor water quality of the water in the river, it contains a large amount of mud, sand and other materials, which will cause wear on the surface of the impeller when it rotates. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the problems raised in the background technology, an impeller with wear resistance and long service life is proposed.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes an impeller that is wear-resistant and has a long service life, comprising an impeller body; a blade is fixedly connected to the top of the impeller body; a slot is provided inside the blade; a cavity is provided inside the blade; a block is slidably connected to the inside of the slot; a wear-resistant protective sleeve plate is fixedly connected to the top of the block; a lock slot is provided inside the block; a lock block is slidably connected to the inside of the cavity; a spring is fixedly connected to the side end of the lock block.

[0007] Preferably, a pull rod is fixedly connected to the side end of the locking block; a pull handle is fixedly connected to the side end of the pull rod; and the pull rod is slidably connected to the inside of the cavity.

[0008] Preferably, a support rod is fixedly connected to the top of the wear-resistant protective sleeve plate; a filter screen is fixedly connected to the top of the support rod and is located at the top of the impeller body.

[0009] Preferably, a rigid protective plate is fixedly connected to the bottom of the filter screen and is arranged in a circular array.

[0010] Preferably, the inner side wall of the wear-resistant protective sleeve plate is fixedly connected with a guide block, and a plurality of guide blocks are provided; the end of the wear-resistant protective sleeve plate is in a spike shape; the side wall of the wear-resistant protective sleeve plate is fixedly connected with a wear-resistant block, and the end of the wear-resistant block is in a semi-arc shape.

[0011] Preferably, the end of the locking block is semi-arc-shaped and is on the same horizontal plane as the locking groove.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model discloses an impeller that is wear-resistant and has a long service life. A wear-resistant protective sleeve is sleeved on the surface of the blade so that the wear-resistant protective sleeve fits the surface of the blade, and then drives the clamping block to be inserted into the inside of the clamping slot, and then squeezes the locking block so that the locking block is squeezed and shrinks into the inside of the cavity and then squeezes the spring to generate elastic force. When the locking slot is aligned with the cavity, the spring generates elastic force to push the locking block to be inserted into the inside of the locking slot for clamping and fixing, so as to fix the cavity on the surface of the blade, thereby achieving the effect of wear resistance and protection.

[0014] 2. The utility model describes an impeller that is wear-resistant and has a long service life. When the wear-resistant protective sleeve needs to be removed, the pull handle is pulled to drive the pull rod to slide toward the side end, thereby driving the pull handle to slide toward the side end, so that the pull handle pulls the locking block to shrink into the interior of the cavity, making it easy for the wear-resistant protective sleeve to slide out of the slot for removal.

When the locking slot 33 is aligned with the cavity 34, the spring 36 generates elastic force to push the locking block 35 into the inside of the locking slot 33 for clamping and fixing, so as to fix the cavity 34 on the surface of the blade, thereby achieving the effect of wear resistance and protection.

[0025] Further, such as Figure 4 As shown, a pull rod 41 is fixedly connected to the side end of the locking block 35; a pull handle 42 is fixedly connected to the side end of the pull rod 41; the pull rod 41 is slidably connected to the inside of the cavity 34; during operation, when the wear-resistant protective sleeve 24 needs to be removed, the pull handle 42 is pulled to drive the pull rod 41 to slide toward the side end, thereby driving the pull handle 42 to slide toward the side end, so that the pull handle 42 pulls the locking block 35 to retract into the inside of the cavity 34, making it easy for the wear-resistant protective sleeve 24 to slide out of the inside of the slot 31 for removal.

[0026] Further, such as Figure 1 As shown, the top of the wear-resistant protective sleeve plate 24 is fixedly connected to a support rod 23; the top of the support rod 23 is fixedly connected to a filter screen 22, and is located at the top of the impeller body 1; when working, the filter screen 22 is installed on the top of the impeller body 1, so that during the circulation of water, the sediment is filtered through the filter screen 22, thereby reducing the problem of wear on the blades.

[0027] Further, such as Figure 2As shown, a rigid protective plate 21 is fixedly connected to the bottom of the filter screen 22 and is arranged in a circular array; when working, a plurality of rigid protective plates 21 are installed at the bottom of the filter screen 22 to protect the blades on the top of the impeller body 1, thereby effectively reducing the problem of wear of the internal blades by external impurities.

[0028] Further, such as Figure 2 As shown, the inner side wall of the wear-resistant protective sleeve plate 24 is fixedly connected with a guide block 26, and there are several guide blocks 26; the end of the wear-resistant protective sleeve plate 24 is in a spike shape; the side wall of the wear-resistant protective sleeve plate 24 is fixedly connected with a wear-resistant block 25, and the end of the wear-resistant block 25 is semi-arc-shaped; when working, the wear-resistant blocks 25 and the guide blocks 26 are fixedly connected on both sides of the wear-resistant protective sleeve plate 24 to guide the water flow and protect against impurities, thereby effectively improving the protection effect on the blades.
