Description

Technical Field

[0001] The invention relates to the technical field of water pipe water flow detection, and in particular to a water pipe water flow detection instrument. Background Art

[0002] In the field of water pipe water flow detection technology, it is usually necessary to use a vibration sensor to contact the outer wall of the water pipe. When water flows in the water pipe, pulsation will be generated, and the vibration generated by the pulsation will be transmitted to the water pipe. The vibration sensor then senses the vibration generated by the pulsation of the water flow in the water pipe and transmits the sensing signal to the detector, so that the detector displays the information that there is water flowing in the water pipe for reference by the staff, and at the same time, sound and light alarms are issued. However, traditional water pipe water flow detection instruments still have problems in actual operation.

[0003] For example, in actual operation, there are many situations in which water flows in a water pipe. When a small water flow flows, the pulsating vibration generated will be relatively small, and the vibration will be further dissipated when transmitted to the water pipe.

[0136] The bolt 40 is rotatably inserted through the sliding sleeve 37 and penetrates the inner side of the second spring 38 to be threadedly connected with the arc recessed block 39 .

[0137] Specifically, the sleeve 37 can provide support for the second spring 38, and the end of the second spring 38 away from the sleeve 37 can provide support for the arc recessed block 39, and the sleeve 37 can provide a through channel for the bolt 40. The sleeve 37 can provide a resistance for the bolt 40, so that the bolt 40 can position the arc recessed block 39 by means of the threaded action, so that the arc recessed block 39 squeezes the second spring 38 to contract and store energy under the support of the sleeve 37.

[0138] In the actual application of this embodiment, before the sleeve 17 is wrapped around the outside of the water pipe 1, the staff needs to insert the bolt 40 through the sleeve 37 and connect it with the bottom thread of the arc recess block 39. Under the resistance of the sleeve 37, the bolt 40 uses the thread action to pull the arc recess block 39 downward, so that the arc recess block 39 squeezes the second spring 38 downward under the action of external force, so that the second spring 38 is squeezed and contracted to store energy under the support of the sleeve 37.

[0139] When wrapping the sleeve 17 around the outside of the water pipe 1 with different diameters, the staff needs to push the sliding sleeve 37 so that the sliding sleeve 37 can use external force to move along the N guide plate 36 under the support of the sleeve 17. At the same time, the sliding sleeve 37 will drive the bolt 40, the second spring 38 and the arc recessed block 39 to move together on the inner side of the guide groove 35, so that the second spring 38 and the arc recessed block 39 are moved to a position of the water pipe 1 away from the arc rubber pad 9.

[0140] After fixing the sleeve 17, rubber sheet 18 and arc rubber pad 9, the staff needs to rotate the bolt 40 so that the bolt 40 is separated from the arc recessed block 39 by the thread action, thereby releasing the tension on the arc recessed block 39. Then, the second spring 38 will use the rebound force to push the arc recessed block 39 upward under the support of the sliding sleeve 37, so that the arc recessed block 39 fits with the outer wall of the water pipe 1 under the elastic force of the second spring 38, and pushes the sliding sleeve 37, the N guide plate 36 and the sleeve 17 downward under the rebound force of the second spring 38, so that the sleeve 17 cooperates with the rubber sheet 18 to squeeze the arc rubber pad 9 downward under the action of external force, so that the arc rubber pad 9 and the conductive rod 12 can fit more closely with the water pipe 1, thereby improving the effect and firmness of vibration transmission.

[0141] Working principle: The rubber material and arc design of the arc rubber pad 9 enable it to fit with the outer wall of the water pipe 1, providing stable support and ensuring efficient transmission of vibration. The longitudinal groove 10 provides deformation space for the arc rubber pad 9 to ensure fit, and the conductive rod 12 directly contacts the water pipe 1 to transmit the vibration to the cone cover 11. The first spring 13 and the striking ball 14 expand the vibration amplitude of the cone cover 11 through elasticity and inertia, thereby enhancing the vibration transmission efficiency.

[0142] Through the combination of the slot 15, the rubber sheet 18, the through slot 20, the support ring 21, the rotating rod 22, the sleeve 24 and the connecting rod 25, the rubber sheet 18 can be inserted into the outside of the water pipe 1 through the arc rubber pad 9 and fit tightly with the water pipe 1. The locking bolt 28, the friction pad 30 and the push rod 29 of the adjusting parts cooperate to achieve the stable positioning of the rubber sheet 18.

[0143] The sliding sleeve 37 slides along the guide groove 35 with the support of the N guide plate 36, moving the second spring 38 and the arc recessed block 39 to the appropriate positions, and the second spring 38 is energy stored by pulling the arc recessed block 39 by the bolt 40. After releasing the bolt 40, the elastic force of the second spring 38 pushes the arc recessed block 39 to fit against the outer wall of the water pipe 1, and at the same time drives the sleeve belt 17, the rubber sheet 18 and the arc rubber pad 9 to squeeze the water pipe 1, thereby improving the firmness of vibration transmission and the tightness of fit.

[0144] The vibration sensor 2 receives the vibration signal transmitted by the cone cover 11 through the sensing end, and transmits the signal to the detector 3 through the connector 4. The detector 3 analyzes the intensity and frequency of the vibration signal and displays it, and at the same time sends out an audible and visual alarm to remind the staff that there is water flowing in the water pipe 1.

[0145] The weak vibration of the water pipe 1 is amplified by the vibration expansion part, and combined with the elastic expansion effect of the first spring 13 and the hitting ball 14, the perception ability of the vibration sensor 2 to the vibration of small flow water is effectively improved to avoid missed detection. The vibration caused by the water flow in the water pipe 1 can be efficiently transmitted to the vibration sensor 2, thereby improving the detection accuracy.

[0146] The close fit of components such as the arc rubber pad 9 and the rubber plate 18 can be adjusted to adapt to water pipes 1 with different diameters, and the application range is wide.

[0147] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
