Description

Technical Field

[0001] The utility model relates to the technical field of Internet of Things water meters, in particular to an automatic alarm Internet of Things water meter. Background Art

[0002] With the advancement of science and technology, IoT water meters are becoming increasingly popular. IoT water meters refer to remote water meters that use IoT private networks. They are the latest generation of remote water meters. As a convenience, IoT water meters can also support remote meter reading. The remote reading of water meter data can be achieved through the background IoT remote meter reading system, which can greatly improve the meter reading efficiency in large and medium-sized cities. The IoT remote meter reading system can be combined with the online revenue platform, which is convenient and fast, solving the inconvenience of having to queue up at the water company regularly in the past.

[0003] At present, the use process of IoT water meters is the same as that of traditional water meters, and water leakage will also occur at the interface. At present, some IoT water meters already have the function of automatic alarm, which can automatically report to the management system when leaking, so that maintenance personnel can quickly rush to the scene for repair. However, the leaked water cannot be collected in this process. The most important thing is that there is a lack of means to temporarily stop the leakage. If the maintenance personnel cannot arrive at the scene in time, a lot of water resources will be wasted before the maintenance. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6The utility model provides an automatic alarm Internet of Things water meter, comprising a water meter body 1, which is installed on a water pipe, a collecting box 2 is arranged below the water meter body 1, a connecting pipe 3 is fixedly arranged on the top of the collecting box 2, a shell 4 is fixedly arranged on the surface of the water meter body 1, the top of the connecting pipe 3 is connected to the shell 4, a cover plate 6 is fixedly installed on the surface of the shell 4 by bolts 5, the cover plate 6 is fixedly arranged on the surface of the water pipe, a groove 26 is arranged on the surface of the shell 4, a sealing ring 27 is engaged inside the groove 26, one side of the sealing ring 27 is in contact with the surface of the cover plate 6, the bolt 5 passes through the sealing ring 27, a blocking mechanism is arranged inside the connecting pipe 3, an alarm mechanism is arranged on the collecting box 2, an inclined surface 23 is arranged at the bottom of the collecting box 2, a drain pipe 24 is arranged at the bottom of the collecting box 2, the drain pipe 24 is arranged as an external thread structure, and the bottom end of the drain pipe 24 is threadedly connected with an end cover 25.

[0027] See also Figure 1 and 4 When in use, the water meter body 1 is directly installed on the water pipe. When water leaks at the connection between the water pipe and the water meter body 1, the leaked liquid will enter between the shell 4 and the cover 6, and enter the collection box 2 through the connecting pipe 3. At this time, the blocking mechanism will block the connecting pipe 3 after sensing the liquid in the collection box 2, thereby realizing a secondary seal of the connection between the water meter body 1 and the water pipe through the connecting pipe 3, the shell 4 and the end cover 25. At the same time, the alarm mechanism is activated to send a warning message to the outside world to remind the maintenance personnel to repair it in time. After the repair is completed, the maintenance personnel rotate the end cover 25 to separate it from the surface of the drain pipe 24. The liquid in the collection box 2 can reach the drain pipe 24 along the inclined surface 23 under the action of gravity. At this time, the liquid in the collection box 2 can be discharged or collected to facilitate the subsequent normal use of the collection box 2.

[0028] It should be noted that the connection between the water pipe and the water meter body 1 is generally a threaded connection, and a sealing tape is wrapped around the contact surface of the two to improve the sealing performance. Therefore, the water pipe needs to be rotated when it is connected to the water meter body 1. At this time, relative rotation will occur between the water pipe and the end cover 25. In this solution, the sealing between the end cover 25 and the water pipe is achieved through the sealing means in the prior art, so that the liquid can enter the connecting pipe 3 inside the shell 4.

[0029] The included angles between the generatrix of the conical chamber 7 and the conical sealing plug 8 and the horizontal plane are the same.

[0030] Specifically, this structure can ensure the sealing between the conical chamber 7 and the conical sealing plug 8. The conical sealing plug 8 is composed of a skeleton and external rubber. In order to further improve the sealing, the connection between the conical sealing plug 8 and the conical chamber 7 can be provided with mutually matching notches or mortise and tenon structures to achieve the effect of improving the sealing.

[0031] The blocking mechanism includes a conical chamber 7, a conical sealing plug 8, a threaded rod 9 and a base 10. The conical chamber 7 is arranged inside the connecting pipe 3, and the conical sealing plug 8 is concentrically arranged inside the conical chamber 7. The angles between the generatrix of the conical chamber 7 and the conical sealing plug 8 and the horizontal plane are the same. The base 10 is fixed to the top of the inner cavity of the collecting box 2, the threaded rod 9 is rotatably arranged on the base 10, and the top end of the threaded rod 9 is threadedly connected to the inside of the conical sealing plug 8. The conical sealing plug 8 is slidably arranged in the conical chamber 7 through a limiting structure, and the threaded rod 9 is connected to the collecting box 2 through a driving mechanism. The limiting structure includes a slide groove 20, a connecting arm 21 and a limiting plate 22. The connecting arm 21 is fixed to the bottom of the conical sealing plug 8, and the limiting plate 22 is integrally formed on the side of the connecting arm 21. The slide groove 20 is arranged on the inner wall of the connecting pipe 3, and the limiting plate 22 is slidably arranged in the slide groove 20.

[0032] See also Figure 2 and 3 The alarm mechanism can sense the liquid in the collection box 2 and control the action of the blocking mechanism. When the threaded rod 9 rotates, it can drive the conical sealing plug 8 to rotate synchronously, and the conical sealing plug 8 can drive the connecting arm 21 to rotate synchronously, but the connecting arm 21 cannot rotate due to the restriction of the limit plate 22 and the slide groove 20. Therefore, the conical sealing plug 8 can move vertically inside the conical chamber 7, and the conical sealing plug 8 can drive the limit plate 22 to move synchronously inside the slide groove 20 through the connecting arm 21. The rotation direction of the threaded rod 9 is set so that it can drive the conical sealing plug 8 to move upward inside the conical chamber 7. At this time, the conical sealing plug 8 can block the water flow inside the conical chamber 7, thereby forming a sealed space inside the shell 4 to prevent liquid from leaking out.

[0033] The driving mechanism includes a driving motor 11 and a rotating shaft 12. The rotating shaft 12 is rotatably arranged at the top of the inner cavity of the collecting box 2. The driving motor 11 is installed on the surface of the collecting box 2 and is connected to the rotating shaft 12. One end of the rotating shaft 12 is connected to the threaded rod 9 through a transmission member. The transmission member includes a synchronous wheel 13 and a synchronous belt 14. The two synchronous wheels 13 are respectively installed on the surface of the threaded rod 9 and the rotating shaft 12. The two synchronous wheels 13 are connected by a synchronous belt 14 for transmission.

[0034] See also Figure 3 The driving motor 11 can drive the rotating shaft 12 to rotate, and the rotating shaft 12 drives the threaded rod 9 to rotate synchronously through the synchronous wheel 13 and the synchronous belt 14. In this embodiment, the driving motor 11 is connected to the alarm mechanism, so that the alarm mechanism can drive the control driving motor 11 to start, so as to realize the rapid action of the conical sealing plug 8.

[0035] The alarm mechanism includes a liquid level sensor 15, a control box 16, a controller 17, a wireless transmission module 18 and a buzzer 19. The control box 16 is fixed to the surface of the collection box 2, the liquid level sensor 15 is installed inside the collection box 2, the controller 17, the wireless transmission module 18 and the buzzer 19 are installed inside the control box 16, the drive motor 11, the liquid level sensor 15, the buzzer 19 and the wireless transmission module 18 are all electrically connected to the controller 17, and the drive motor 11, the liquid level sensor 15, the buzzer 19, the wireless transmission module 18 and the controller 17 are all powered by the built-in battery of the water meter body 1.

[0036] See also Figure 1 , 5 and 6. When the liquid enters the collecting box 2, the liquid level in the collecting box 2 will gradually rise. At this time, the liquid in the collecting box 2 triggers the liquid level sensor 15, and the liquid level sensor 15 transmits the signal to the controller 17. The controller 17 controls the drive motor 11 to start, so as to realize the sealing of the conical chamber 7 by the conical sealing plug 8, and the controller 17 can control the buzzer 19 to make a sound to remind the nearby maintenance personnel. The maintenance personnel can also receive the signal from the wireless transmission module 18 through the mobile terminal (such as a mobile phone, tablet) or the background system to realize online alarm.

[0037] It should be noted that the drive motor 11, the liquid level sensor 15, the controller 17, the wireless transmission module 18 and the buzzer 19 are well-known technical means in the prior art, and their specific structures and working principles are not described in detail here.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
