Description

Technical Field

[0001] The present invention relates to the technical field of smart water meters, in particular to a waterproof and moisture-proof smart water meter. Background Art

[0002] Water meters are usually used to measure water flow, mostly cumulative measurements of water usage. With the rapid development of society, water meters are becoming more and more popular in our lives, providing great convenience for people's lives. At the same time, when choosing the specifications of a water meter, you should first estimate the size of the water flow used under normal circumstances and select a suitable water meter.

[0003] Patent publication number CN216246588U discloses a waterproof and moisture-proof smart water meter, relating to the field of smart water meter technology. Specifically, the waterproof and moisture-proof smart water meter comprises a water meter body mounted within an outer shell, with connecting pipes mounted on both sides of the water meter body, and through-holes adapted for the connecting pipes are provided in the middle of both inner sidewalls of the outer shell. The waterproof and moisture-proof smart water meter, comprising an outer shell, a water meter body, a reinforcement assembly, and a drying assembly, is configured such that, during use, the water meter body is mounted within the outer shell. The outer shell is secured with feet to prevent direct contact between the outer shell and the ground. After the water pipe is connected to the connecting pipe, a knob stud is rotated to tighten the curved plate against the water pipe, providing excellent reinforcement. After installation, a sealed cover is placed on the water meter body. A dryer within the drying box dries the air entering the outer shell, preventing the water meter body from becoming damp, thereby increasing its service life.

[0004] However, the device currently has some shortcomings: the device can dry the air to prevent the water meter body from getting damp, but the air inside the water meter is difficult to flow. When the temperature is too high, the metering elements inside the water meter body will malfunction, resulting in errors in the metering data. Therefore, we propose a waterproof and moisture-proof smart water meter. Summary of the Invention

[0005] In response to the deficiencies of the prior art, the present invention provides a waterproof and moisture-proof smart water meter, which solves the problem in the above background technology that air is difficult to flow inside the water meter, and the metering elements inside the water meter body may malfunction when the temperature is too high.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a waterproof and moisture-proof intelligent water meter, comprising a water meter, water pipes are arranged on both sides of the water meter, and also comprising a circulating ventilation device, an anti-fogging device, an anti-freezing device and a leakage alarm device, wherein the circulating ventilation device is arranged outside the water meter, the anti-fogging device is arranged inside the circulating ventilation device, the anti-freezing device is arranged on the back of the anti-fogging device, and the leakage alarm device is arranged on the left and right sides of the circulating ventilation device, the circulating ventilation device comprises a waterproof shell, an electric telescopic column and a baffle, and the back of the inner wall of the waterproof shell is fixedly connected to the back of the water meter, The front of the waterproof shell is transparent, and ventilation holes are provided on the left and right sides of the waterproof shell. The good sealing performance of the waterproof shell provides an excellent waterproof effect for the water meter to prevent the water meter from being soaked and eroded by water. The bottom of the electric telescopic column is fixedly installed on the bottom of the inner wall of the waterproof shell, and the electric telescopic columns are symmetrically distributed with the water meter as the center. The bottom of the baffle is fixedly installed on the top of the telescopic end of the electric telescopic column, and the ventilation holes are located on the movement trajectory of the baffle. When the telescopic end of the electric telescopic column moves upward, it will push the baffle to move synchronously. After the baffle moves upward, it will leave the cover on the ventilation holes of the waterproof shell, so that internal heat and moisture can be discharged.

[0007] Preferably, the circulating ventilation device also includes a connecting rod spring plate and a protrusion. The left side of the connecting rod spring plate is fixedly installed on the right side surface of the baffle, and the connecting rod spring plate is symmetrically distributed with the water meter as the center. The back side of the protrusion is fixedly installed on the back side of the inner wall of the waterproof shell, and the protrusion is located on the movement trajectory of the connecting rod spring plate. When the baffle moves up, it drives the connecting rod spring plate to move synchronously, and the connecting rod spring plate contacts the protrusion. When the connecting rod spring plate continues to move up and completely passes the protrusion, the connecting rod spring plate will restore through its own elasticity, and will swing up and down during the restoration process of the connecting rod spring plate, thereby accelerating the air flow inside the waterproof shell and accelerating the rapid replacement of internal air and external air.

[0008] Preferably, the anti-fogging device includes a resist plate, a U-shaped frame, a roller and a spring piece. The right side of the resist plate is fixedly mounted on the left side of the baffle, and the upper and lower sides of the U-shaped frame are slidably mounted on the upper and lower sides of the inner wall of the waterproof shell, and the U-shaped frame is located on the movement trajectory of the resist plate. The upper and lower ends of the roller are rotatably mounted on the upper and lower sides of the inner wall of the U-shaped frame, and the outer surface of the roller is in front contact with the inner wall of the waterproof shell, and the spring piece is fixedly mounted between the right side of the U-shaped frame and the right side of the inner wall of the waterproof shell. When the baffle moves up, it drives the resist plate to move synchronously. When the resist plate moves up, it will contact the U-shaped frame, so that the U-shaped frame generates a force to move to the right and slides to the right. When the U-shaped frame slides to the right, it will contact the spring piece, so that the spring piece is deformed synchronously. The reciprocating movement of the U-shaped frame drives the roller to do so synchronously. At this time, the roller will rotate and absorb the fog water generated on the surface of the waterproof shell due to the large temperature difference between day and night, so as to prevent the fog water from blocking the water meter.

[0009] Preferably, the anti-fogging device further comprises an L-shaped plate and a capsule, wherein the bottom of the L-shaped plate is fixedly mounted at the top center of the shrapnel, the right side of the capsule is fixedly mounted on the right side of the inner wall of the waterproof shell, and a desiccant is provided inside the capsule, and the bottom of the capsule contacts the top surface of the L-shaped plate. When the shrapnel is deformed, the L-shaped plate is driven to move up and down, and when the L-shaped plate moves upward, it contacts the bottom of the capsule, causing the capsule to deform. When the contact force disappears, the capsule recovers through its own elasticity, and absorbs the mist water on the surface of the waterproof shell during the expansion and contraction deformation of the capsule, and dries the mist water through the desiccant inside the capsule.

[0010] Preferably, the antifreeze device includes a connecting column, a U-shaped plate and a heating component. The front of the connecting column is fixedly installed on the back of one end of the bottom of the U-shaped frame, the front of the U-shaped plate is fixedly installed on the back of the connecting column, and the left and right sides of the U-shaped plate are penetrated and slidably installed on the outer surface of the water pipe. The left and right movement of the U-shaped frame drives the connecting column to move synchronously, and the connecting column drives the U-shaped plate to move synchronously. When the U-shaped plate moves left and right, the movable range of the heating component is expanded. The bottom of the heating component is fixedly installed at the bottom center of the inner wall of the U-shaped plate, and the heating component is located directly below the water meter. The heat dissipated by the heating component heats the water meter to prevent the internal temperature from being too low, which causes the water meter to freeze and crack.

[0011] Preferably, the antifreeze device also includes a hinged plate, a cylinder and a non-Newtonian fluid sac. The right side of the bottom of the hinged plate is hinged to the left surface of the bottom of the waterproof shell, and the hinged plate is symmetrically distributed with the waterproof shell as the center. When the outside of the waterproof shell is impacted, the hinged plate preferentially contacts the impactor to avoid direct contact between the impactor and the waterproof shell and causing damage to the waterproof shell. The left side of the cylinder is fixedly installed on the right side of the hinged plate, and the end of the cylinder close to the water meter passes through the waterproof shell and the U-shaped plate. The left side of the non-Newtonian fluid sac is fixedly installed on the right end of the cylinder, and the non-Newtonian fluid sac is located below the water meter. When the hinged plate is subjected to impact force, it will drive the cylinder to move synchronously toward the center of the waterproof shell. The cylinder drives the non-Newtonian fluid sac to move synchronously, and the non-Newtonian fluid sac will suddenly collide with another non-Newtonian fluid sac, so that the non-Newtonian fluid sac instantly hardens to form support, offsetting the impact force.

[0012] Preferably, the leakage alarm device includes a sensing box and an alarm component. The right side of the sensing box is fixedly installed on the left side of the waterproof shell, and a sensor for sensing water droplets is provided inside the sensing box. The water pipe runs through the sensing box, and the sensing boxes are symmetrically distributed with the waterproof shell as the center. The bottom of the alarm component is fixedly installed on the top surface of the sensing box. When the water pipe interface drips due to aging, the dripping water droplets will fall onto the inner wall of the sensing box. When the inner wall of the sensing box senses the falling water droplets, it will transmit a signal to the alarm component. The alarm component will issue an alarm in time, thereby reminding maintenance personnel to rush to the site for maintenance and repair in time.

[0013] The sliding block is slidably mounted on the top of the inner wall of the sensing box, and a spring is fixedly connected between the left side of the sliding block and the left side of the inner wall of the sensing box. The inclined surface of the sliding block is located on the movement track of the top of the T-shaped block, and the telescopic end of the electric push rod drives the scraper block to move in the direction close to the water pipe. At the same time, the electric push rod will also drive the T-shaped block to move downward, and the T-shaped block will resist the sliding block and move along the bottom of the inner wall of the sensing box towards the water pipe. At this time, the inner wall of the sensing box is scraped around by the sliding block, T-shaped block and scraping block, so that the dripping water droplets and small water droplets splashed are collected, so that the water droplets can be concentrated in one place, thereby accelerating the sensing speed of the sensing box to the water droplets.

[0014] The present invention provides a waterproof and moisture-proof smart water meter. It has the following beneficial effects: (1) The present invention provides a good waterproof effect for the water meter through the setting of circulating ventilation and the setting of the waterproof shell, so that the good sealing performance of the waterproof shell provides an excellent waterproof effect for the water meter, thereby preventing the water meter from being soaked and corroded by water; through the cooperation of the electric telescopic column and the baffle, when the telescopic end of the electric telescopic column moves upward, it will push the baffle to move synchronously, and the baffle will leave the cover of the vent of the waterproof shell, so that internal heat and moisture can be discharged, thereby preventing long-term internal air from not flowing and causing adverse effects on the water meter, thereby causing the internal metering element of the water meter to malfunction, thereby affecting the accurate recording of water consumption; through the cooperation of the baffle, the connecting rod spring plate and the protrusion, when the connecting rod spring plate moves upward, it will contact the protrusion, and when the connecting rod spring plate continues to move upward and completely passes the protrusion, the connecting rod spring plate will recover through its own elasticity, and will swing up and down during the recovery process of the connecting rod spring plate, thereby accelerating the air flow inside the waterproof shell, accelerating the rapid replacement of internal air and external air, and further avoiding the failure of the water metering element.

[0015] (2) The present invention sets an anti-atomization device, and cooperates with the baffle, the resisting plate, the U-shaped frame, the roller and the spring sheet, so that when the resisting plate moves up, it will resist the U-shaped frame to slide to the right, and the U-shaped frame will resist the spring sheet and deform synchronously. When the resisting force disappears, the thrust of the spring sheet when it recovers pushes the U-shaped frame to reset. When the U-shaped frame resets, it will resist the resisting plate and the baffle to descend, thereby increasing the number of contacts between the connecting rod spring plate and the protrusion, thereby accelerating the air flow inside the waterproof shell; it can also make the roller start to rotate due to the friction generated when it contacts the surface of the waterproof shell, and the reciprocating movement of the U-shaped frame drives the roller to do so synchronously. At this time, the roller will rotate and absorb the mist water generated on the surface of the waterproof shell due to the large temperature difference between day and night, so as to prevent the mist water from blocking the water meter, thereby affecting the staff's judgment on whether the water meter is counting normally; through the cooperation of the spring piece, L-shaped plate and capsule, the L-shaped plate will contact the bottom of the capsule when moving upward, causing the capsule to deform. When the resistance force disappears, the capsule recovers through its own elasticity. During the expansion and contraction process of the capsule, it will absorb the mist water on the surface of the waterproof shell and dry the mist water through its own internal desiccant to prevent the mist water from overflowing again, while also speeding up the elimination of the mist water on the surface of the waterproof shell.

[0016] (3) The present invention heats the water meter by setting up an antifreeze device and a heating component, thereby preventing the internal temperature from being too low and causing the water meter to freeze and crack, thereby shortening the service life of the water meter. By coordinating the U-shaped frame, the connecting column and the U-shaped plate, the U-shaped plate will expand the range of movement of the heating component when it moves left and right, making the heating of the water meter more uniform, avoiding local uneven heating that causes damage to the water meter, and avoiding increased maintenance costs. By coordinating the hinged plate, the cylinder and the non-Newtonian fluid capsule, when the outside of the waterproof shell is hit, the hinged plate will first contact the impacting object, avoiding direct contact between the impacting object and the waterproof shell to cause damage to the waterproof shell, thereby causing water seepage inside the waterproof shell in the later stage. The non-Newtonian fluid capsule can also suddenly hit another non-Newtonian fluid capsule, thereby causing the non-Newtonian fluid capsule to instantly harden and form a support, offsetting the impact force, avoiding the water meter from shifting and the water pipe from being disconnected when the impact force is too large, and ensuring normal water supply.

[0017] (4) The present invention sets a leakage alarm device, and cooperates with the induction box and the alarm component so that the dripping water droplets will fall to the inner wall of the induction box. When the inner wall of the induction box senses the falling water droplets, it will transmit the signal to the alarm component. The alarm component will sound an alarm in time, thereby reminding the maintenance personnel to rush to the site for maintenance and repair in time, avoiding affecting the normal water supply and avoiding wasting water resources; through the cooperation of the electric push rod, scraper block, T-shaped block and sliding block, the sliding block, T-shaped block and scraper block scrape around the inner wall of the induction box, thereby collecting the small water droplets splashed by the dripping water droplets, so that the water droplets can be concentrated in one place, thereby accelerating the sensing speed of the induction box to the water droplets, thereby accelerating the alarm reminder speed, and preventing the water pipe from dew phenomenon from aggravating, thereby increasing the difficulty of maintenance and maintenance expenses.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0021] See also Figure 1-4The present invention provides a technical solution: a waterproof and moisture-proof smart water meter, comprising a water meter 1, water pipes 2 are arranged on both sides of the water meter 1, and also comprising a circulating ventilation device 3 and an anti-fogging device 4. The circulating ventilation device 3 is arranged outside the water meter 1, and the anti-fogging device 4 is arranged inside the circulating ventilation device 3. The circulating ventilation device 3 comprises a waterproof shell 31, an electric telescopic column 32 and a baffle 33. The back of the inner wall of the waterproof shell 31 is fixedly connected to the back of the water meter 1. The front of the waterproof shell 31 is transparent, and ventilation holes are arranged on the left and right sides of the waterproof shell 31. The waterproof shell 31 is well connected to the back of the water meter 1. Good sealing provides excellent waterproof effect for the water meter 1, preventing the water meter 1 from being soaked and corroded by water. The bottom of the electric telescopic column 32 is fixedly installed on the bottom of the inner wall of the waterproof shell 31, and the electric telescopic column 32 is symmetrically distributed with the water meter 1 as the center. The bottom of the baffle 33 is fixedly installed on the top of the telescopic end of the electric telescopic column 32, and the vent is located on the movement trajectory of the baffle 33. When the telescopic end of the electric telescopic column 32 moves upward, it will push the baffle 33 to move synchronously. After moving upward, the baffle 33 will leave the cover on the vent of the waterproof shell 31, allowing internal heat and moisture to be discharged.

[0022] The circulating ventilation device 3 also includes a connecting rod spring plate 34 and a protrusion 35. The left side of the connecting rod spring plate 34 is fixedly installed on the right surface of the baffle 33, and the connecting rod spring plate 34 is symmetrically distributed with the water meter 1 as the center. The back of the protrusion 35 is fixedly installed on the back of the inner wall of the waterproof shell 31, and the protrusion 35 is located on the movement trajectory of the connecting rod spring plate 34. When the baffle 33 moves upward, it drives the connecting rod spring plate 34 to move synchronously, and the connecting rod spring plate 34 contacts the protrusion 35. When the connecting rod spring plate 34 continues to move upward and completely passes the protrusion 35, the connecting rod spring plate 34 will restore through its own elasticity. During the restoration process of the connecting rod spring plate 34, it will swing up and down, thereby accelerating the air flow inside the waterproof shell 31 and accelerating the rapid replacement of internal air and external air.

[0023] The anti-fogging device 4 includes a plate 41, a U-shaped frame 42, a roller 43 and a spring 44. The right side of the plate 41 is fixedly mounted on the left side of the baffle 33. The upper and lower sides of the U-shaped frame 42 are slidably mounted on the upper and lower sides of the inner wall of the waterproof shell 31, and the U-shaped frame 42 is located on the movement track of the plate 41. The upper and lower ends of the roller 43 are rotatably mounted on the upper and lower sides of the inner wall of the U-shaped frame 42, and the outer surface of the roller 43 is in front contact with the inner wall of the waterproof shell 31. The spring 44 is fixedly mounted on the right side of the U-shaped frame 42 and the inner wall of the waterproof shell 31. When the baffle 33 moves upward, it drives the support plate 41 to move synchronously. When the support plate 41 moves upward, it will contact the U-shaped frame 42, causing the U-shaped frame 42 to generate a force to move rightward and slide to the right. When the U-shaped frame 42 slides to the right, it will contact the spring piece 44, causing the spring piece 44 to deform synchronously. The reciprocating movement of the U-shaped frame 42 drives the roller 43 to do so synchronously. At this time, the roller 43 will rotate and absorb the fog water generated on the surface of the waterproof shell 31 due to the large temperature difference between day and night, so as to prevent the fog water from blocking the water meter 1.

[0024] The anti-fogging device 4 also includes an L-shaped plate 45 and a capsule 46. The bottom of the L-shaped plate 45 is fixedly mounted at the top center of the spring piece 44. The right side of the capsule 46 is fixedly mounted on the right side of the inner wall of the waterproof shell 31. A desiccant is provided inside the capsule 46. The bottom of the capsule 46 contacts the top surface of the L-shaped plate 45. When the spring piece 44 is deformed, it drives the L-shaped plate 45 to move up and down. When the L-shaped plate 45 moves upward, it will contact the bottom of the capsule 46, causing the capsule 46 to deform. When the resistance force disappears, the capsule 46 recovers through its own elasticity. During the expansion and contraction deformation process of the capsule 46, it absorbs the mist water on the surface of the waterproof shell 31 and dries the mist water through the desiccant inside itself.

[0025] When in use, the water meter 1 is located inside the waterproof shell 31. The good sealing performance of the waterproof shell 31 provides the water meter 1 with an excellent waterproof effect, preventing the water meter 1 from being soaked and corroded by water. When the water meter 1 needs to be ventilated, the electric telescopic column 32 is started. When the telescopic end of the electric telescopic column 32 moves upward, it pushes the baffle 33 to move synchronously. After the baffle 33 moves upward, it leaves the vent of the waterproof shell 31, allowing internal heat and moisture to be discharged, preventing long-term internal air stagnation from causing adverse effects on the water meter 1, thereby causing the internal metering components of the water meter 1 to malfunction, thereby affecting the accurate recording of water consumption. When the baffle 33 moves upward, it drives the connecting rod spring 34 When the connecting rod spring plate 34 moves upward, it will contact the protrusion 35. At this time, the connecting rod spring plate 34 will bend downward and deform. When the connecting rod spring plate 34 continues to move upward and completely passes the protrusion 35, the connecting rod spring plate 34 will recover through its own elasticity. During the recovery process, the connecting rod spring plate 34 will swing up and down, thereby accelerating the air flow inside the waterproof shell 31 and accelerating the rapid replacement of the internal air and the external air, further avoiding the failure of the metering element of the water meter 1; at the same time, the up and down swinging of the connecting rod spring plate 34 can also accelerate the upper and lower gas circulation inside the waterproof shell 31, promote the circulation of the gas inside the waterproof shell 31, and improve the maintenance effect of the metering element.

[0026] When the baffle 33 moves upward, it drives the resisting plate 41 to move synchronously. When the resisting plate 41 moves upward, it will contact the U-shaped frame 42, causing the U-shaped frame 42 to generate a force to move to the right and thus slide to the right. When the U-shaped frame 42 slides to the right, it will contact the spring piece 44, causing the spring piece 44 to deform synchronously. When the resistance force disappears, the thrust of the spring piece 44 when it recovers pushes the U-shaped frame 42 to reset. When the U-shaped frame 42 is reset, it will contact the resisting plate 41 and the baffle 33 to move down, thereby increasing the number of contacts between the connecting rod spring plate 34 and the protrusion 35, thereby accelerating the air flow inside the waterproof shell 31; at the same time, when the U-shaped frame 42 slides to the right, it will drive the roller 43 to move synchronously. The roller 43 starts to rotate due to the friction generated when it contacts the surface of the waterproof shell 31, and the reciprocating movement of the U-shaped frame 42 drives the roller 43 synchronously In this way, the surface of the roller 43 is made of plush material. At this time, the roller 43 will rotate and absorb the mist water generated on the surface of the waterproof shell 31 due to the large temperature difference between day and night, so as to prevent the mist water from blocking the water meter 1, thereby affecting the staff's judgment on whether the water meter 1 is counting normally; when the spring piece 44 is deformed, it will drive the L-shaped plate 45 to move up and down. When the L-shaped plate 45 moves upward, it will contact the bottom of the capsule 46, causing the capsule 46 to deform. When the resistance force disappears, the capsule 46 recovers through its own elasticity. The suction force generated during the expansion and contraction deformation of the capsule 46 will suck the mist water on the surface of the waterproof shell 31 into itself through the square opening on its own surface. At this time, the mist water is dried by the desiccant inside itself to prevent the mist water from overflowing again, and at the same time, the speed of eliminating the mist water on the surface of the waterproof shell 31 is also accelerated. Example 2

[0027] See also Figure 1-7 Based on Example 1, this embodiment further includes an antifreeze device 5 and a leakage alarm device 6.

The front of the connecting column 51 is fixedly installed on the back of one end of the bottom of the U-shaped frame 42, the front of the U-shaped plate 52 is fixedly installed on the back of the connecting column 51, and the left and right sides of the U-shaped plate 52 are penetrated and slidably installed on the outer surface of the water pipe 2. The left and right movement of the U-shaped frame 42 drives the connecting column 51 to move synchronously, and the connecting column 51 drives the U-shaped plate 52 to move synchronously. When the U-shaped plate 52 moves left and right, the movable range of the heating component 53 is expanded. The bottom of the heating component 53 is fixedly installed at the bottom center of the inner wall of the U-shaped plate 52, and the heating component 53 is located directly below the water meter 1. The heat dissipated by the heating component 53 heats the water meter 1 to prevent the internal temperature from being too low, which may cause the water meter to freeze and crack.

[0028] The antifreeze device 5 also includes a hinged plate 54, a cylinder 55, and a non-Newtonian fluid sac 56. The right side of the bottom of the hinged plate 54 is hinged to the left surface of the bottom of the waterproof shell 31, and the hinged plates 54 are symmetrically distributed with the waterproof shell 31 as the center. When the outside of the waterproof shell 31 is hit, the hinged plate 54 contacts the impactor first to prevent the impactor from directly contacting the waterproof shell 31 and causing damage to the waterproof shell 31. The left side of the cylinder 55 is fixedly installed on the right side of the hinged plate 54, and the end of the cylinder 55 close to the water meter 1 passes through the waterproof shell 31 and the U-shaped plate 52. The left side of the non-Newtonian fluid sac 56 is fixedly installed on the right end of the cylinder 55, and the non-Newtonian fluid sac 56 is located below the water meter 1. The non-Newtonian fluid sac 56 is made of soft elastic metal. When the hinged plate 54 is subjected to impact force, it will drive the cylinder 55 to move synchronously toward the center of the waterproof shell 31. The cylinder 55 drives the non-Newtonian fluid sac 56 to move synchronously. The non-Newtonian fluid sac 56 will suddenly collide with another non-Newtonian fluid sac 56, so that the non-Newtonian fluid sac 56 instantly hardens to form a support, offsetting the impact force.

[0029] The leakage alarm device 6 includes a sensing box 61 and an alarm component 62. The right side of the sensing box 61 is fixedly installed on the left side of the waterproof shell 31, and a sensor for sensing water droplets is arranged inside the sensing box 61. The water pipe 2 runs through the sensing box 61, and the sensing box 61 is symmetrically distributed with the waterproof shell 31 as the center. The bottom of the alarm component 62 is fixedly installed on the top surface of the sensing box 61. When the interface of the water pipe 2 drips due to aging, the dripping water droplets will fall onto the inner wall of the sensing box 61. When the inner wall of the sensing box 61 senses the falling water droplets, it will transmit a signal to the alarm component 62. The alarm component 62 will issue an alarm in time, thereby reminding maintenance personnel to rush to the site for maintenance and repair in time.

[0030] The leakage alarm device 6 also includes an electric push rod 63, a scraper block 64, a T-shaped block 65 and a sliding block 66. The left side of the electric push rod 63 is fixedly installed on the left side of the inner wall of the induction box 61, and the electric push rod 63 is symmetrically distributed with the water pipe 2 as the center. The left side of the scraper block 64 is fixedly installed on the left side of the telescopic end of the electric push rod 63. The bottom of the T-shaped block 65 is hinged to the top of the telescopic end of the electric push rod 63. The sliding block 66 is slidably installed on the top of the inner wall of the induction box 61, and a spring is fixedly connected between the left side of the sliding block 66 and the left side of the inner wall of the induction box 61. The inclined surface of the sliding block 66 is located at the T-shaped On the movement trajectory of the top of the block 65, the telescopic end of the electric push rod 63 drives the scraping block 64 to move toward the water pipe 2. At the same time, the electric push rod 63 also drives the T-shaped block 65 to move downward. The T-shaped block 65 will resist the sliding block 66 and move along the bottom of the inner wall of the sensing box 61 toward the water pipe 2. At this time, the sliding block 66, the T-shaped block 65 and the scraping block 64 are used to scrape the inner wall of the sensing box 61, so as to collect the small water droplets splashed by the dripping water droplets, so that the water droplets can be concentrated in one place, thereby speeding up the sensing speed of the sensing box 61 to the water droplets.

[0031] When in use, in cold weather, the heating component 53 is started, and the heat dissipated by the heating component 53 is used to heat the water meter 1 to prevent the internal temperature from being too low, which may cause the appearance of the water meter to freeze and crack, thereby shortening the service life of the water meter 1; the left and right movement of the U-shaped frame 42 drives the connecting column 51 to move synchronously, and the connecting column 51 drives the U-shaped plate 52 to move synchronously. When the U-shaped plate 52 moves left and right, the range of movement of the heating component 53 is expanded, making the heating of the water meter 1 more uniform, avoiding damage to the water meter 1 caused by uneven local heating, and avoiding increased maintenance costs; when the outside of the waterproof shell 31 is impacted, the hinged plate 54 takes priority Contact with the impact object to avoid direct contact between the impact object and the waterproof shell 31, which may cause damage to the waterproof shell 31 and water seepage inside the waterproof shell 31 in the future; when the hinged plate 54 is subjected to the impact force, it will drive the cylinder 55 to move synchronously toward the center of the waterproof shell 31, and the cylinder 55 will drive the non-Newtonian fluid capsule 56 to move synchronously. The non-Newtonian fluid capsule 56 will suddenly collide with another non-Newtonian fluid capsule 56, so that the non-Newtonian fluid capsule 56 will instantly harden to form a support, offsetting the impact force, avoiding the water meter 1 from shifting and the water pipe 2 from being disconnected when the impact force is too large, and ensuring normal water supply.

[0032] When the interface of the water pipe 2 starts to drip due to aging, the dripping water drops will fall to the inner wall of the induction box 61. When the inner wall of the induction box 61 senses the falling water drops, it will transmit a signal to the alarm component 62. The interior of the induction box 61 is a sensing environment composed of a sensor, and the induction box 61 and the alarm component 62 are closely connected as a whole through the sensor. The alarm component 62 will sound an alarm in time, thereby reminding the maintenance personnel to rush to the site for maintenance and repair in time to avoid affecting the normal water supply and avoiding water waste. At the same time, the induction box 61 will automatically start the electric push rod 63, and the extension and contraction of the electric push rod 63 The end drives the scraper 64 to move toward the water pipe 2. At the same time, the electric push rod 63 also drives the T-shaped block 65 to move downward. When the T-shaped block 65 moves downward, it will interfere with the sliding block 66 and move along the bottom of the inner wall of the sensing box 61 toward the water pipe 2. At this time, the sliding block 66, the T-shaped block 65 and the scraper block 64 scrape the inner wall of the sensing box 61 around, so as to collect the dripping water droplets and the small water droplets splashed, so that the water droplets can be concentrated in one place, thereby speeding up the sensing speed of the sensing box 61 to the water droplets, thereby speeding up the alarm reminder speed, and preventing the dew phenomenon in the water pipe 2 from worsening, thereby increasing the difficulty of maintenance and maintenance expenses.
