Description
Technical Field
[0001] The present invention relates to the technical field of intelligent water meters, and in particular to an intelligent multifunctional water meter. Background Art
[0002] With the development of intelligence, water meters have also changed from manual meter reading to smart water meters with networked remote recording. Existing smart water meters use electronic processing modules to detect and remotely transmit water meter data, so that water usage can be viewed online.
[0003] However, in many water meters, metal manhole covers are installed in some water meter wells. In order to reduce power consumption, the signal power intensity of the smart water meter will be relatively low. This causes the smart water meter to be very unstable in deeper water meter wells, resulting in data loss. Moreover, if a water pipe ruptures in the water meter well, the smart water meter will be submerged for a long time, which will also cause damage to the internal electronic processing module.

[0026] The working principle of the first embodiment of the present invention is as follows: the water inlet pipe of the main base meter 1 is connected to the tap water pipe, and the water flow drives the magnetic needle 101 of the main base meter 1 to rotate. Each time the magnetic needle 101 passes through the reed switch probe 201, a metering pulse is generated and transmitted to the central information processing module 203. The central information processing module 203 performs data statistics and displays the numbers on the display screen 202. The central information processing module 203 can also transmit the data to the data center remotely through the antenna module 5. The electric drive gear box 204 is driven by a motor. The electric drive gear box 204 starts to drive the valve stem of the water valve 102 to rotate to realize the control of opening and closing the water valve 102. The water flow drives the inner worm gear 301 to rotate, and the inner worm gear 301 drives the generator 303 to rotate to transmit power to the central information processing module 203 and charge the battery of the intelligent module 2. The generator 303 also shares and supplements the power consumption of the liquid level sensor 401 and the antenna module 5, reduces the power consumption rate of the battery of the intelligent module 2, and prolongs the service life of the internal battery of the intelligent module 2. The antenna module 5 is adsorbed on the gaps around the manhole cover of the water meter well by magnets. The antenna module 5 is close to the gaps to facilitate signal transmission, reduce the shielding of the metal manhole cover on the antenna module 5 signal, and the antenna module 5 is better connected to the external wireless network. The central information processing module 203 improves the stability of the external wireless network connection through the antenna module 5, avoiding the problem of unstable wireless transmission signals when the central information processing module 203 is deep in the water meter well. The antenna module 5 is extended by the extension line 501, and the hub 502 rotates to surround the extension line 501 for collection; The liquid level sensor 401 can sense the liquid level below. The two side connecting slides 402 of the side shear fork frame 404 move closer along the slide groove of the liquid level sensor 401, and the side shear fork frame 404 extends downward. The tightening nut 403 moves along the thread of the side connecting slide column 402 to tighten the liquid level sensor 401 to fix the height position of the liquid level sensor 401. As the side shear fork frame 404 is adjusted in telescopic manner and the distance from the ground, the liquid level sensor 401 starts to monitor the water on the ground at a fixed time, especially in some underground water meter wells. By monitoring the liquid level in the water meter well, it is possible to monitor whether the pipeline is leaking or there is too much water, and the water level is too high. The data is automatically alarmed through the information processing module 203 and the antenna module 5; When the liquid level sensor 401 senses that water is approaching, the motor of the upper electric threaded rod 210 starts to drive the upper electric threaded rod 210 to rotate, and the upper electric threaded rod 210 moves along the internal threads of the lower threaded tube 208 to increase the height, and the smart module 2 and the upper electric threaded rod 210 are increased in height synchronously, and after the upper electric threaded rod 210 moves to the inner smooth surface 209, it can slide upwards without following the threads. At this time, the lower support spring 206 supports the smart module 2 and the upper electric threaded rod 210 to increase synchronously and rapidly, speeding up the height increase speed of the smart module 2, and the interval setting of the internal threads of the lower threaded tube 208 can be used for multi-stage height increase adjustment to avoid the situation where the smart module 2 is soaked by water. After the smart module 2 is increased, it needs to be manually assisted by personnel to descend and return to its original position; When the inner worm gear 301 is stuck or stops rotating, the water pressure will press the sealing plate 307 and the side U-shaped tube 306 to separate, and a flow channel will appear between the sealing plate 307 and the side U-shaped tube 306. The water flows through the side U-shaped tube 306 to bypass the inner worm gear 301 and enter the household pipe, reducing the impact on the user's water use. When the inner worm gear 301 rotates freely, the water flows through the inner worm gear 301 to enter the household pipe, and the outer support spring 304 supports the sealing plate 307 and the side U-shaped tube 306 to fit and seal, preventing the water from bypassing the inner worm gear 301 from the side U-shaped tube 306. When the inner worm gear 301 is damaged, the inner worm gear 301 and the generator 303 are separated and replaced along with the fixing cover 302 and the power generation base valve body 3, eliminating the need to disassemble the power generation base valve body 3 and the pipeline.
