Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to a water meter protection device and a use method thereof. Background Art

[0002] With the development of water conservancy projects, water meters, as an important tool for measuring water volume, play an indispensable role in daily life. Existing water meters are divided into recycled water meters and tap water meters. Recycled water meters are generally installed outdoors in buildings, such as in green belts, beside roads, etc. Due to the relatively harsh operating environment, the service life of recycled water meters is relatively short. In order to extend the service life, regular maintenance and inspection are required. When traditional recycled water meters are installed outdoors, a water meter well needs to be built with cement and steel bars. The project is large in scale and costly, and it is not convenient for later inspection and maintenance.

[0003] In addition, in the prior art, a shell is usually set on the outside of the water meter to protect the water meter. The Chinese utility model patent (application number: 201920805362.6) proposes a water meter anti-theft protection device, which connects the two ends of the water meter and the water pipe through a flange and places them together inside the shell to protect the water meter and the connection structure. However, such a setting is that the water meter is connected on both sides of the shell through flanges, which is not convenient for the staff to install, and is even more inconvenient for the subsequent disassembly, maintenance and maintenance of the water meter; and the Chinese utility model patent (application number: 202321135729.0) proposes a smart water meter with anti-theft function, and the protective cover provided therein can only protect the water meter body itself, and cannot protect the connection structure between the two sides of the water meter and the pipeline. Moreover, if the water meter is placed outdoors, it is also necessary to consider how to achieve anti-theft protection for it. Summary of the Invention

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In a typical embodiment of the present invention, Figure 1-2As shown, a water meter protection device is proposed, including a box body 15, a first water pipe joint 1 is installed on one side of the box body 15, and the first water pipe joint 1 extends to the inner side of the box body 15 and is installed with a connector 3, and the distance between the connector 3 and the first water pipe joint 1 is adjustable; a second water pipe joint 2 is installed on the other side of the box body 15 away from the first water pipe joint 1, and a ball valve 4 is installed on the inner side of the second water pipe joint 2 extending to the inner side of the box body 15;

[0030] A water meter 7 is provided inside the box 15 . One end of the water meter 7 is detachably connected to the connector 3 , and one end of the water meter 7 away from the connector 3 is overlapped with the ball valve 4 .

[0031] In this embodiment, by arranging the water meter 7 and the connection structure between the water meter 7 and the pipeline inside the box 15, it is possible to replace the water meter 7 well built by reinforced concrete in the prior art, thereby protecting the water meter 7 and its connection structure, avoiding a large amount of engineering work while reducing the protection cost of the water meter 7.

[0032] In addition, by providing a connecting piece 3 and making the distance between the connecting piece 3 and the first water pipe joint 1 adjustable, the end of the water meter 7 away from the connecting piece 3 is overlapped with the ball valve 4. When the water meter 7 needs to be installed in the box 15, by adjusting the distance between the connecting piece 3 and the first water pipe joint 1, a suitable installation distance is provided for the water meter 7 to be placed between the first water pipe joint 1 and the second water pipe joint 2, and one end of the water edge is abutted against the ball valve 4, and the other end is connected to the first water pipe joint 1 through the hexagonal joint 13 by adjusting the connecting piece 3 again. At the same time, the water meter 7 is pressed against the ball valve 4 of the second water pipe joint 2 to achieve sealing. Such operation makes it more convenient for the operator to install the water meter 7 and perform subsequent disassembly and maintenance, greatly speeding up the workers' work efficiency.

[0033] Furthermore, both the first water pipe connector 1 and the second water pipe connector 2 are threaded connectors, and the radial dimension of the ends of the first water pipe connector 1 and the second water pipe connector 2 away from the housing 15 is smaller than the radial dimension of the ends closer to the housing 15. In this embodiment, the connection portions between the first water pipe connector 1 and the second water pipe connector 2 and the housing 15 are both locked with hexagonal nuts 5, facilitating the connection of the first water pipe connector 1 and the second water pipe connector 2 to the external pipeline while ensuring a tight seal.

[0034] Furthermore, a gasket 6 is provided at the connection between the connector 3 and the first water pipe joint 1. This arrangement ensures that when the distance between the connector 3 and the first water pipe joint 1 is adjusted, no interference damage occurs between the connector 3 and the first water pipe joint 1, thereby avoiding damage to the connector 3 due to excessive adjustment.

[0035] Furthermore, the box body 15 includes a box cover 16, which is detachably connected to the box body 15. Since the water meter 7 is used outdoors, the box body 15 can protect the internal water meter 7 in a sealed state, and the detachable box cover 16 also facilitates the operator to perform subsequent disassembly and maintenance.

[0036] Furthermore, a slot structure is provided at one end of the box cover 16, and a protrusion is provided at the contact portion of the box body 15 with the box cover 16, which engages with the slot structure. A lock structure 14 is provided at the end of the box cover 16 away from the slot structure. In this embodiment, a strip-shaped protrusion is provided on the right side of the box body 15, and a slot structure is provided at the contact portion of the box cover 16 with the box body 15. The protrusion and slot structure engage to achieve a detachable connection between the box cover 16 and the box body 15. Simultaneously, a lock structure 14 is provided on the left side, and a protrusion is also provided at the contact portion of the box body 15 with the box cover 16. The lock structure 14 cooperates with the protrusion structure to achieve the opening and locking of the box cover 16 and the box body 15.

[0037] Furthermore, the lock body structure 14 is provided with a control component 11 and a slide groove, and a spring 12 and a cylindrical pin 8 are provided in the slide groove. The spring 12 can be tightened and relaxed under the action of the control component 11. The spring 12 abuts against the cylindrical pin 8, and the cylindrical pin 8 can approach or move away from the side wall of the box body 15 under the action of the spring 12.

[0038] Furthermore, the box cover 16 is provided with a digital display component 9 and a password disk 10 which are in communication with the control component 11. The control component 11 is used to receive the password and verify it, and after the verification is passed, the control spring 12 is tightened and relaxed.

[0039] In this embodiment, the cylindrical pin 8 cooperates with the raised structure provided on the left side of the box body 15. When the box cover 16 needs to be opened, the control component 11 receives the correct password and controls the spring 12 to contract. At this time, the cylindrical pin 8 moves to the right to open the box cover 16; when closing the box cover 16, the box cover 16 and the box body 15 are closed. At the same time, the control component 11 controls the spring 12 to relax, and the cylindrical pin 8 moves to the left to achieve the locking of the box cover 16 and the box body 15.

[0040] Furthermore, an alarm module is provided on the box cover 16 and is connected to the control component 11. The alarm module will alarm when it detects abnormal vibration of the box body 15 and the box cover 16 through the connected vibration sensor, or when the alarm module detects that the password is entered incorrectly multiple times.

[0041] The alarm module can sound an alarm if the box body 15 or the box lid 16 is illegally pried. Illegal prying specifically refers to the unauthorized separation of the box lid 16 from the box body 15 by external force or objects, or other circumstances that cause the box body 15 to vibrate abnormally. In this embodiment, a vibration sensor is built into the lock body structure 14 and can keenly capture abnormal vibrations caused by illegal operations. Once these abnormal vibration signals are detected, the sensor will immediately activate and transmit an alarm signal to the connected alarm module, which will then activate and sound an alarm, thereby ensuring the security of the box body 15 and preventing unauthorized access or theft.

[0042] In a second aspect of the present invention, a method for using a water meter protection device is provided, comprising:

[0043] When installing the water meter 7, open the box cover 16, overlap one end of the water meter 7 with the ball valve 4, screw the connector 3 on the other end to adjust the distance between the connector 3 and the first water pipe joint 1, and connect the connector 3 to the first water pipe joint 1. After connection, screw the connector 3 so that the end of the water meter 7 overlapping the ball valve 4 is squeezed and sealed. After the water meter 7 is installed, close the box cover 16, and connect the first water pipe joint 1 and the second water pipe joint 2 to the external water supply pipe;

[0044] When repairing the water meter 7, open the box cover 16, screw the connector 3 to separate it from the first water pipe joint 1, and loosen the end of the water meter 7 that is connected to the ball valve 4. Remove the water meter 7 for repair and maintenance.

[0045] Furthermore, the box cover 16 is opened as follows: the lock structure 14 on the box cover 16 receives the password and verifies it, and then opens the box cover 16 after the verification is passed, wherein the password is sent by the mobile phone in response to the user's instruction or sent by the password disk 10;

[0046] The alarm module will sound an alarm when it detects that the box 15 is illegally pried, or when it detects that the password is entered incorrectly for multiple times.

[0047] The water meter protection device and usage method provided by the present invention have low cost, are easy to install and use, can ensure the tightness of the connection between the water meter and the pipeline to avoid water leakage, can be remotely controlled and have an anti-theft function, and the water meter placed inside the protection device and its connection structure are easy to disassemble, maintain and service, which greatly improves the maintenance efficiency of the staff.
