[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-6 and Figure 9As shown, the present invention provides a technical solution: a 4G electromagnetic water meter with anti-tamper alarm function, including a water meter body 1, which is used for water measurement. The water meter body 1 includes an insulating lining 101, and a water pipe 102 is bonded to the outer wall of the insulating lining 101. Two rings 103 are fixedly sleeved on the outer wall of the water pipe 102. A sealing ring 104 is bonded to the opposite side of each of the two rings 103. The two sealing rings 104 are movably sleeved on the outer wall of the water pipe 102. The outer wall of the water pipe 102 is provided with two coils 106 and two sets of fixing members 105. The coil 106 is fixed to the outer wall of the water pipe 102. An electrode 107 is installed inside each through-hole of the outer wall of the water pipe 102. The sensing end of each electrode 107 movably penetrates the outer wall of the insulating lining 101 and extends into the interior of the insulating lining 101. A main protective shell 108 and a secondary protective shell 109 are installed between the outer walls of the two rings 103. The main protective shell 108 and the secondary protective shell 109 are fixed together by bolts and nuts. The surfaces of the two sealing rings 104 are in contact with the inner walls of the main protective shell 108 and the secondary protective shell 109. A main storage tube 110 is attached to the top of the main protective shell 108. The interior of the main storage tube 110 is connected to the interior of the main protective shell 108. A set of mounting posts 111 are fixed to the bottom of the inner wall of the main storage tube 110. A converter 113 is installed between the tops of the set of mounting posts 111. The converter 113 is located inside the main storage tube 110. A battery 112 is placed at the bottom of the inner wall of the main storage tube 110. A main tube cover 114 is attached to the top of the main storage tube 110. A display 115 is installed inside the main tube cover 114. The display end of the display 115 is movably sleeved on the main tube cover 114. Inside the through hole of 4, a secondary storage tube 116 is installed at the connecting end of the main storage tube 110. The interior of the secondary storage tube 116 is connected to the interior of the main storage tube 110. A set of limiting blocks 117 are fixed to the inner wall of the secondary storage tube 116. The bottom of each limiting block 117 is fixed to the bottom of the inner wall of the secondary storage tube 116. A communication module 118 is placed between the grooves of the set of limiting blocks 117. A secondary tube cover 119 is installed at the top of the secondary storage tube 116. An antenna 120 is installed at the top of the secondary tube cover 119. Cameras 121 are installed inside the two detection ends of the main storage tube 110.

[0035] In this embodiment, when it is necessary to measure the amount of water flowing from inside the 4G electromagnetic water meter, the start button on the display 115 is pressed to start the 4G electromagnetic water meter. The coil 106 (excitation coil) in the started 4G electromagnetic water meter generates a stable magnetic field perpendicular to the water flow direction. When the conductive liquid (water) passes through the interior of the insulating liner 101, it cuts the magnetic field lines. The detection electrode 107 then captures the induced electromotive force and processes it, i.e., amplifies the signal. The detection electrode 107 then transmits the processed analog signal to the converter 113. The converter 113 converts the received analog signal into a digital signal and continues processing it. Simultaneously, it combines preset parameters such as "nominal diameter" and "pulse equivalent" to calculate the real-time water volume and accumulate the total water consumption. Then, the converter 113 transmits both the calculated real-time water volume data and the total water consumption data to the remote management platform via a 4G network through the communication module 118 and the antenna 120. The system provides monitoring personnel on the remote management platform with real-time images. Simultaneously, two cameras 121 capture real-time images of the position between the inlet of the 4G electromagnetic water meter and the outlet of one of the water pipes, as well as the position between the outlet of the 4G electromagnetic water meter and the inlet of the other water pipe. The two cameras 121 then transmit the captured image data to the converter 113. The converter 113 processes the received image data and, through the communication module 118 and antenna 120, transmits the processed image data to the remote management platform via the 4G network. When the remote management platform receives the real-time images, it compares them with preset images of the 4G electromagnetic water meter under normal installation conditions. If the result is abnormal, it indicates that the 4G electromagnetic water meter has been disassembled, and the remote management platform will issue an alarm. The monitoring personnel who receive the alarm will then dispatch personnel to investigate.

[0036] Example 2: According to Figures 1-4 and Figures 6-9As shown, the water meter body 1 is equipped with an auxiliary mechanism 2. The auxiliary mechanism 2 is used to extend the length of the inlet and outlet of the 4G electromagnetic water meter. The auxiliary mechanism 2 includes two first flanges 201 and two mounting slots 206. Six connecting blocks 202 are fixed on the opposite sides of the two first flanges 201. The opposite sides of the two first flanges 201 are in contact with second flanges 203. An auxiliary tube 205 is fixedly sleeved inside each second flange 203. Three of the connecting blocks 202 on each first flange 201 are fixedly equipped with perforated blocks 212. Three cylindrical holes 217 are pre-set on the surface of each first flange 201. A limit rod 211 is movably sleeved inside each cylindrical hole 217. Each perforated block 212 has pre-set auxiliary holes 213 on its surface. A movable block 214 is slidably connected inside each auxiliary hole 213. An arc-shaped anti-slip pad 215 is adhered to the inner surface of each movable block 214. A hand-tightening screw 216 is threaded through the top of each movable block 214 near both ends. Two rectangular anti-slip pads 218 are adhered to the upper side of each slider 209. Sealing gaskets 204 are adhered to the opposite sides of the two second flanges 203. Two auxiliary tubes 205 are movably fitted inside the two first flanges 201. A sealing ring 207 is provided inside each mounting groove 206. The surface of each sealing ring 207 contacts the inner wall of each auxiliary tube 205. Three connecting blocks 202 on the first flange 201 have pre-set grooves 208 on their surfaces. A slider 209 is slidably connected inside each groove 208. An auxiliary block 210 is fixed to the surface of each slider 209. Each limiting rod 211 is fixedly fitted into the through hole of each auxiliary block 210. The side of each limiting rod 211 near the corresponding second flange 203 is fixed to the surface of the corresponding second flange 203. Each limiting rod 211 is movably fitted into the through hole of each perforated block 212. The outer surface of each limiting rod 211 contacts the inner surface of each arc-shaped anti-slip pad 215. The threaded end of each hand-tightening screw 216 is rotatably embedded in the corresponding... On the surface of the perforated block 212, two rectangular anti-slip pads 218 on each slider 209 are in contact with the inner wall of the corresponding groove 208. The water meter body 1 includes an insulating lining 101. The two ends of the insulating lining 101 are in contact with the opposite sides of two sealing gaskets 204. A water pipe 102 is bonded to the outer wall of the insulating lining 101. Two mounting grooves 206 are preset at both ends of the outer wall of the water pipe 102. The inner walls of the two auxiliary pipes 205 are fixed to the outer walls of the insulating lining 101 and the outer walls of the water pipe 102. Two rings 103 are fixedly sleeved on the outer wall of the water pipe 102. The connecting block 202 on each first flange 201 is fixed to the surface of the corresponding ring 103.

[0037] In this embodiment, when the 4G electromagnetic water meter needs to be installed between two water pipes, the second flange 203 corresponding to the water inlet end is moved horizontally and stably using the cooperation of the cylindrical hole 217, the corresponding slide groove 208, the corresponding slider 209, the corresponding auxiliary block 210, the corresponding rectangular anti-slip pad 218, and the corresponding limit rod 211. When the sealing gasket 204 attached to the moving second flange 203 comes into contact with the outlet end of one of the water pipes, the second flange 203 is fixed to the outlet end of one of the water pipes using accurate bolts and nuts. Then, the above operation steps are repeated to move the second flange 203 corresponding to the outlet end until the second flange 203 is fixed to the other water pipe. After fixing the inlet end of one water pipe together, turn the two hand screws 216 on one of the perforated blocks 212. At this time, the two hand screws 216, in cooperation with the corresponding perforated block 212, the corresponding slide groove 208, the corresponding rectangular anti-slip pad 218, the corresponding auxiliary block 210, the corresponding slider 209, the corresponding moving block 214, the corresponding arc-shaped anti-slip pad 215 and the fixed connecting block 202, will press and fix the corresponding limit rod 211. Then repeat the above operation steps to press and fix all the remaining limit rods 211. When all the limit rods 211 have been fixed, the connection operation between the 4G electromagnetic water meter and the two water pipes to be connected is completed.

[0038] The overall effect and working principle of the mechanism are as follows:

[0039] In the preparation stage, all coils 106, all electrodes 107, batteries 112, converters 113, displays 115, communication modules 118, antennas 120, and all cameras 121 are connected in accordance with electrical connection safety and accuracy and drawing requirements. Then, the nominal diameter, pulse equivalent, and magnetic field strength of the 4G electromagnetic water meter are set using the control buttons on the display 115. Next, the converter 113 is wirelessly connected to the remote management platform using the cooperation of the communication module 118 and the antenna 120.

[0040] During the installation phase, when it is necessary to install the 4G electromagnetic water meter between two water pipes, first utilize the water inlet end of the 4G electromagnetic water meter (from...). Figure 1As shown, the left side is the water inlet and the right side is the water outlet. The corresponding cylindrical hole 217, corresponding slide groove 208, corresponding slider 209, corresponding auxiliary block 210, corresponding rectangular anti-slip pad 218, and corresponding limit rod 211 work together to stably and horizontally move the second flange 203 corresponding to the water inlet. When the sealing gasket 204 adhered to the moving second flange 203 contacts the water outlet of one of the water pipes, the second flange 203 is then fixed to the water outlet of one of the water pipes using precise bolts and nuts (at this time, the corresponding sealing gasket 204 can increase the seal between the second flange 203 and the water outlet of one of the water pipes). The above steps are then repeated, moving the second flange 203 corresponding to the water outlet until the first flange is complete. After fixing the two flanges 203 together with the inlet end of another water pipe, turn the two hand screws 216 on one of the perforated blocks 212. At this time, the two hand screws 216 will press and fix the corresponding limit rod 211 in the cooperation of the corresponding perforated block 212, the corresponding slide groove 208, the corresponding rectangular anti-slip pad 218, the corresponding auxiliary block 210, the corresponding slider 209, the corresponding moving block 214, the corresponding arc-shaped anti-slip pad 215 and the fixed connecting block 202. Then repeat the above operation steps to press and fix all the remaining limit rods 211. When all the limit rods 211 have been fixed, the connection operation between the 4G electromagnetic water meter and the two water pipes to be connected is completed.

[0041] During the metering phase, when it is necessary to measure the amount of water flowing from inside the 4G electromagnetic water meter, the start button on the display 115 is pressed to activate the 4G electromagnetic water meter. The coil 106 (excitation coil) in the activated 4G electromagnetic water meter generates a stable magnetic field perpendicular to the water flow direction. When the conductive liquid (water) passes through the insulating liner 101, it cuts the magnetic field lines. The detection electrode 107 then captures the induced electromotive force and processes it (i.e., amplifies the signal). The detection electrode 107 then transmits the processed analog signal to the converter 113. The converter 113 converts the received analog signal into a digital signal and continues processing it. Simultaneously, it combines preset parameters such as "nominal diameter" and "pulse equivalent" to calculate the real-time water volume and accumulate the total water consumption. Finally, the converter 113 transmits both the calculated real-time water volume data and the total water consumption data to the remote management platform via a 4G network through the communication module 118 and the antenna 120. The system is designed for monitoring personnel on a remote management platform. Simultaneously, two cameras 121 capture real-time images of the position between the inlet of the 4G electromagnetic water meter and the outlet of one of the water pipes, as well as the position between the outlet of the 4G electromagnetic water meter and the inlet of the other water pipe. The two cameras 121 then transmit the captured image data to a converter 113. The converter 113 processes the received image data and, through the communication module 118 and antenna 120, transmits the processed image data to the remote management platform via a 4G network. When the remote management platform receives the real-time images, it compares them with preset images of the 4G electromagnetic water meter under normal installation conditions. If the result is abnormal, indicating that the 4G electromagnetic water meter has been disassembled, the remote management platform will issue an alarm. The monitoring personnel receiving the alarm will then dispatch personnel to investigate.
