DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The embodiment of the present invention provides a water meter protection structure, as Figure 1As shown in the figure, it includes a first liquid level detector 19 and a protective housing 4. The first liquid level detector 19 is installed at a first preset height position on the inner wall of the water meter well. The protective housing 4 is sleeved outside the water meter 1 in the water meter well, and the inlet pipe and outlet pipe of the water meter 1 both pass through the side wall of the protective housing 4. The top end of the protective housing 4 is provided with an opening, and a top cover for opening or closing the opening is provided at the opening.

[0019] In the water meter protection structure of the embodiment of the present invention, the first liquid level detector 19 installed on the inner wall of the water meter well is used to monitor the liquid level height in the water meter well in real time. At the same time, the protective housing 4 is sleeved outside the water meter 1 to surround the water meter 1. Once it is detected that the liquid level in the water meter well reaches the preset height, the top cover can be covered on the opening, so that the water meter is located in the sealed protective housing, preventing water from entering the protective housing, thereby forming the first protection line of defense for the water meter. The water meter protection structure of the embodiment of the present invention can effectively prevent the water meter from being flooded and ensure the normal use of the water meter.

[0020] Preferably, a sealing ring 18 is provided at the connection between the inlet pipe and outlet pipe of the water meter 1 and the side wall of the protective housing 4. The sealing ring 18 is used to fill the gap between the side wall of the protective housing 4 and the connection of the inlet pipe and outlet pipe, effectively preventing water from entering the protective housing 4 and further protecting the water meter.

[0021] As a preferred example, a second liquid level detector 5-1 is provided in the protective housing 4, and the second liquid level detector 5-1 is arranged at the bottom end of the water meter 1. The bottom end of the protective housing 4 is provided with a first drain pipe communicating with the inner cavity of the protective housing. In this preferred embodiment, if the water in the water meter well rises to the top end of the protective housing 4 and enters the protective housing 4 from the opening, or the water outside the water meter well enters the protective housing 4 from above the protective housing 4 through the opening, the water in the protective housing 4 rises. The second liquid level detector 5-1 located at the bottom end of the water meter 1 detects that there is water at the bottom end of the water meter 1, then notifies the user to deal with it in time. At the same time, the first drain pipe at the bottom end of the protective housing 4 can drain the water in the protective housing 4 to prevent the water in the protective housing 4 from continuing to rise and flooding the water meter, thereby forming the second protection line of defense for the water meter.

[0022] Furthermore, a third liquid level detector 5-2 and a suction pump are also provided in the protective housing 4. The third liquid level detector 5-2 is arranged at the top end of the water meter 1, and the outlet of the suction pump is communicated with the first drain pipe. If no timely treatment is carried out after the second liquid level detector 5-1 issues a notification, or a flood breaks out and water suddenly surges into the protective housing 4, causing the water meter 1 to be flooded. In this preferred embodiment, the third liquid level detector 5-2 located at the top end of the water meter 1 detects that there is water at the top end of the water meter 1, then notifies the user to deal with it in time, and at the same time controls the suction pump to suck the water in the protective housing 4 and discharge it through the first drain pipe, shortening the time for the water meter to be flooded, thereby forming the third protection line of defense for the water meter.

[0023] Considering that when the first liquid level detector 19, the second liquid level detector 5-1 or the third liquid level detector 5-2 issues a liquid level signal, since it is impossible to timely check whether the water pipe in the water meter well is broken and causes water, in order to prevent the water meter well from continuing to admit water, as a preferred example, the water meter protection structure of this preferred embodiment further includes a drainage device. The drainage device includes a second drain pipe 12, a control valve 20 and a reservoir 13. One end of the second drain pipe 12 is connected to the water inlet pipe of the water meter 1, and the other end of the second drain pipe 12 is connected to the reservoir 13. The control valve 20 is provided at the connection between the second drain pipe 12 and the water inlet pipe of the water meter 1. The reservoir 13 is located outside the water meter well. Once the first liquid level detector 19, the second liquid level detector 5-1 or the third liquid level detector 5-2 issues a liquid level signal, the control valve 20 is opened, so that the incoming water flows into the reservoir 13 through the control valve 20 and the second drain pipe 12, reducing the water flowing into the pipes in the water meter well, preventing the water in the water meter well from increasing continuously, providing time for troubleshooting and maintenance, and thus forming the fourth protection line of defense for the water meter.

[0024] Further, a first soluble food-grade color film 16 is provided at the second preset height position on the inner side wall of the reservoir 13, and a first camera device 14 is provided on the top inner wall of the reservoir 13. The first camera device 14 is used to monitor the color change of the water body in the reservoir. In this preferred embodiment, the second preset height position is the maximum capacity height of the reservoir 13. When the water body reaches the second preset height, the first soluble food-grade color film 16 dissolves in the water body, causing the water body to change color. The color change of the water body can be monitored by the first camera device 14, and the control valve 20 can be closed in time before the reservoir 13 is filled with water to avoid the water in the reservoir 13 from overflowing.

[0025] Preferably, a fourth liquid level detector 15 is further provided in the reservoir 13. The fourth liquid level detector 15 is added to detect the liquid level height in the reservoir 13 and jointly monitor with the first camera device 14 to further ensure that the water volume in the reservoir 13 is appropriate.

[0026] As a preferred example, the top cover includes a cover body and a driving member. The cover body is rotatably connected to the protection housing 4, and the driving member is connected to the cover body and is used to drive the cover body to rotate. The opening of the protection housing can be opened and closed by controlling the driving member to drive the cover body to rotate, without manual operation, which saves time and effort and can be operated in time.

[0027] As a preferred example, the water meter protection structure of this preferred embodiment further includes a temperature detection device 6, a heating device 7, an exhaust device 8, and a humidity detection device 9. The temperature detection device 6, the heating device 7, the exhaust device 8, and the humidity detection device 9 are all installed in the water meter well. In this preferred embodiment, the temperature detection device 6 is used to detect the temperature in the water meter well. If the temperature is greater than the preset high temperature value, the exhaust device 8 is started to cool down. If the temperature is lower than the preset low temperature value, the control device starts the heating device 7 to heat, so that the water meter is in a suitable temperature environment to ensure the normal use of the water meter. The humidity detection device 9 is used to detect the humidity in the water meter well. If the humidity is greater than the preset humidity value, the exhaust device 8 is started to dehumidify. If the humidity is lower than the preset low temperature value, no device is started, so that the water meter is in a suitable humidity environment to ensure the normal use of the water meter.

[0028] Preferably, the water meter protection structure of the embodiment of the present invention further includes an alarm device and a control device 21. The control device 21 is connected to the first liquid level detector 19, the second liquid level detector 5-1, the third liquid level detector 5-2, the fourth liquid level detector 15, the control valve 20, the first imaging device 14, the driving member, the temperature detection device 6, the heating device 7, the exhaust device 8, the humidity detection device 9, and the alarm device. The control device 21 is used to receive the liquid level signals sent by the first liquid level detector 19 and / or the second liquid level detector 5-1 and / or the third liquid level detector 5-2 and / or the fourth liquid level detector 15, receive the video signal sent by the first imaging device 14, receive the temperature signal sent by the temperature detection device 6, receive the humidity signal sent by the humidity detection device 9, and send an alarm signal to the alarm device, and send a control signal to the control valve 20 and / or the driving member and / or the heating device 7 and / or the exhaust device 8.

[0029] Preferably, the water meter protection structure of the embodiment of the present invention further includes a second imaging device 17. The second imaging device 17 is disposed on the inner wall of the water meter well and is used to monitor the liquid level height in the water meter well, and jointly monitor with the first liquid level detector 19 to further ensure that the water in the water meter well will not flood the water meter.

[0030] Preferably, the first liquid level detector 19, the second liquid level detector 5-1, the third liquid level detector 5-2, and the fourth liquid level detector 15 can adopt an ultrasonic liquid level sensor, a resistive liquid level sensor, an optical liquid level sensor, or a pressure liquid level sensor.

[0031] As a preferred example, a second soluble food-grade color film 10 is provided at the water inlet of the water meter 1, and a third soluble food-grade color film 11 is provided at the water outlet of the water meter 1. The second soluble food-grade color film 10 and the third soluble food-grade color film 11 have different colors. An observation window is provided on the water outlet pipe of the water meter 1 for observing the color of the water body in the water outlet pipe. In this preferred embodiment, when the new water meter is used for the first time after being installed, the incoming water reaches the water inlet of the water meter 1, causing the second soluble food-grade color film 10 to dissolve in the water, and the water body changes color. The water body flows through the water meter and reaches the water outlet of the water meter 1, causing the third soluble food-grade color film 11 to dissolve in the water, and the water body changes color again, and it is a mixture of two colors. The color of the water flowing out of the water meter can be observed through the observation window. If the water body is a mixture of two colors, it indicates that the seals at both ends of the water meter are intact before use, otherwise it indicates that the water meter is not in its original factory state.

[0032] The working process of the water meter protection structure according to the embodiment of the present invention is as follows:

[0033] When the new water meter is used for the first time after being installed, the incoming water reaches the water inlet of the water meter 1, and the second soluble food-grade color film 10 dissolves in the water, and the water body changes color. The water body flows through the water meter and reaches the water outlet of the water meter 1, and the third soluble food-grade color film 11 dissolves in the water, and the water body changes color again, and it is a mixture of two colors. The color of the water flowing out of the water meter is observed through the observation window. If the water body is a mixture of two colors, it indicates that the seals at both ends of the water meter are intact before use, otherwise it indicates that the water meter is not in its original factory state.

[0034] The first liquid level detector 19 installed on the inner wall of the water meter well monitors the liquid level height in the water meter well in real time. If the liquid level in the water meter well reaches the preset height, the first liquid level detector 19 sends a liquid level signal to the control device 21, and the control device 21 sends a control signal to the driving member. The driving member acts to drive the top cover to rotate and cover the opening, so that the water meter is located in the closed protective housing, preventing water from entering the protective housing. At the same time, the control device 21 sends an alarm signal to the alarm device, and the alarm device issues an alarm to remind the staff to check. Thus, the first protection line of defense for the water meter is formed.

[0035] If not dealt with in time, the water in the water meter well rises to the top of the protective housing 4 and enters the protective housing 4 through the opening, or the water outside the water meter well enters the protective housing 4 through the opening above the protective housing 4, and the water in the protective housing 4 rises. The second liquid level detector 5-1 located at the bottom end of the water meter 1 detects that there is water at the bottom end of the water meter 1, then sends a liquid level signal to the control device 21, and the control device 21 sends an alarm signal to the alarm device, and the alarm device issues an alarm to remind the staff to deal with it in time. At the same time, the first drain pipe at the bottom end of the protective housing 4 can drain the water in the protective housing 4 to prevent the water in the protective housing 4 from continuing to rise and flooding the water meter. Thus, the second protection line of defense for the water meter is formed.

[0036] If it has not been processed in time, or if a flood breaks out and water rushes into the protection housing 4 all at once, the water meter 1 will be submerged. The third liquid level detector 5-2 located at the top of the water meter detects the presence of water at the top of the water meter 1, and then sends a liquid level signal to the control device 21. The control device 21 sends an alarm signal to the alarm device, and the alarm device issues an alarm to remind the staff to process it in time. At the same time, the control device 21 sends a control signal to the suction pump, and the suction pump sucks the water in the protection housing 4 and discharges it through the first drain pipe, shortening the time for the water meter to be submerged. Thus, a third protection line for the water meter is formed.

[0037] If the control device 21 receives a liquid level signal sent by one or more of the first liquid level detector 19, the second liquid level detector 5-1 or the third liquid level detector 5-2, it sends a control signal to the control valve 20. The control valve 20 opens, allowing the incoming water to flow into the reservoir 13 through the control valve 20 and the second drain pipe 12, reducing the water flowing into the pipes in the water meter well and preventing the water in the water meter well from increasing continuously, providing time for troubleshooting and maintenance. Thus, a fourth protection line for the water meter is formed. When the water body in the reservoir 13 reaches the second preset height, the first soluble food-grade color film 16 dissolves in the water body, causing the water body to change color. The color change of the water body can be monitored by the first camera device 14, and the control valve 20 can be closed in time before the reservoir 13 is full of water to prevent the water in the reservoir 13 from overflowing.

[0038] The temperature detection device 6 continuously detects the temperature in the water meter well. If the temperature is greater than the preset high temperature value, the control device activates the exhaust device 8 for cooling. If the temperature is lower than the preset low temperature value, the control device activates the heating device 7 for heating, so that the water meter is in a suitable temperature environment to ensure the normal use of the water meter. The humidity detection device 9 continuously detects the humidity in the water meter well. If the humidity is greater than the preset humidity value, the control device activates the exhaust device 8 for dehumidification. If the humidity is lower than the preset low temperature value, no device is activated, so that the water meter is in a suitable humidity environment to ensure the normal use of the water meter.

[0039] The water meter protection structure according to the embodiment of the present invention forms a first protection line for the water meter by setting the first liquid level detector 19 and the protection housing with an openable and closable top cover; forms a second protection line for the water meter by setting the second liquid level detector 5-1 and the first drain pipe; forms a third protection line for the water meter by setting the third liquid level detector 5-2 and the suction pump; and forms a fourth protection line for the water meter by setting the drainage device. By forming four protection lines for the water meter, the water in the water meter well can be effectively prevented from being submerged in various situations, ensuring the normal use of the water meter.

Those skilled in the art should understand that the present invention is not limited by the above specific embodiments, and the above specific embodiments and the descriptions in the specification are only for further illustrating the principles of the present invention.
