Embodiment 1

[0030] see Figure 1 to Figure 6 , a detachable water meter impeller protection device, including an impeller 1, the bottom of the impeller 1 is provided with a buffer mechanism 2, the interior of the buffer mechanism 2 contains a fixed block 201, and a groove is opened on the fixed block 201, and the size of the groove is the same as The bottom end of the impeller 1 is matched to fix the impeller 1; the outer side of the bottom of the fixed block 201 is provided with a screw 202, the size of the screw 202 matches the groove inside the limit block 204, and the screw 202 rotates in the reverse direction. It can cooperate with the groove on the limit block 204 to make the pressing column 206 move down; The grooves are matched, and the deceleration block 203, the clamping block 205, the pressing column 206 and the spring 207 are used together to obtain a certain buffer when the impeller 1 rotates, thereby reducing the impact force of the water flow on the front of the impeller 1;...

Embodiment 2

[0032] see Figure 5 to Figure 7 , a detachable water meter impeller protection device, including a connection block 301, the bottom of the connection block 301 is fixedly connected with an outer rotation block 302, the shape of the outer rotation block 302 is a ring, and a certain number of card slots are opened inside. The size of the rotating block 302 matches the ratchet 303, and the outer rotating block 302 rotates under the drive of the connecting block 301; the inner of the outer rotating block 302 is clamped with a ratchet 303, and the ratchet 303 can stop the entire device when it rotates in the reverse direction; the ratchet 303 There are metal blocks 304 inside, the number of metal blocks 304 is two, and the shape is a rectangle bent from the middle. The metal block 304 defines the position of the friction block 310. When the reverse rotation stops, the friction block 310 return to original position;

Abstract

The invention relates to the technical field of water meters, and discloses a detachable water meter impeller protection device which comprises an impeller, a buffer mechanism is arranged at the bottom of the impeller, a fixing block is arranged in the buffer mechanism, a threaded part is arranged on the outer side of the bottom of the fixing block, and the size of the threaded part is matched with that of a groove in a limiting block. The bottom of the threaded piece is fixedly connected with a speed reduction block, the speed reduction block is composed of a certain number of hemispheres, the size of the speed reduction block is matched with that of the groove in the clamping block, a limiting block is arranged on the outer side of the threaded piece, the clamping block is arranged in the limiting block, and a groove is formed in the top of the clamping block; according to the detachable water meter impeller protection device, the gear at the bottom of the impeller is meshed with the gear-shaped notch in the top of the fixing block, the position of the impeller is fixed, meanwhile, the gear-shaped appearance and the notch are fixed more tightly, and the situation that the impeller shakes in the water meter under the impact of water flow, and consequently the impeller is impacted and damaged is prevented.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a detachable water meter impeller protection device. Background technique [0002] The horizontal screw-wing water meter, also known as the turbine-type water meter, means that the screw axis of the water meter is parallel (or coincident) with the axis of the tap water pipe, and its impeller adopts the shape of a screw wing. The impeller is an important component of the water meter. The water flows into the water meter through the water inlet, and the impeller inside the water meter starts to rotate driven by the water flow, and the flow of water passing through is calculated by the rotation of the impeller. [0003] Most of the impellers used in water meters on the market today are made of plastic. When the water meter starts to operate, the water flow will enter the water meter from the water inlet. Under the impact of the water flow, the impeller will shake and cause dama...
