An intelligent waterproof cut-off device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 4, an intelligent waterproof cut-off device 1 according to an embodiment of the present invention includes:

and a box body (not shown in the figure) which forms the appearance of the cut-off device, contains the components therein, and is provided with an operation key or an operation touch key on the surface, wherein the box body is internally provided with components such as a valve body 10, a liquid level monitoring frame 11, a connecting rod 12, a buoyancy ball 121 and the like.

The valve body 10 is internally provided with a valve cavity and used for sealing a water container; the valve body 10 can be installed on a water container such as a pipeline, so that the valve cavity is communicated with the water container such as the pipeline to monitor the water level in the water container such as the pipeline, and whether the water container such as the pipeline leaks or not is judged.

The liquid level monitoring frame 11 is arranged on the upper portion of the valve body 10 and used for driving components such as a connecting rod 12, a motor, a gear rack 16 and the like, and specifically, a first driving component and a second magnetic driving component are installed on the liquid level monitoring frame 11 along the height direction of the liquid level monitoring frame.

Specifically, the connecting rod 12 penetrates through the valve body 10, that is, one end of the connecting rod 12 is located on one side of the valve cavity, the other end of the connecting rod 12 is located on one side of the liquid level monitoring, a buoyancy ball 121 is installed on one end of the connecting rod 12 located in the valve cavity, and the connecting rod 12 can move in the depth direction of the valve cavity under the driving of the buoyancy ball 121.

Specifically, the first driving assembly includes a first magnetic sensor 131, a first motor 132 electrically connected to the first magnetic sensor 131, and a first gear 133 connected to a driving shaft of the first motor 132.

The second driving assembly includes a second magnetic sensor 141, a second motor 142 electrically connected to the second magnetic sensor 141, and a second gear 143 connected to a driving shaft of the second motor 142.

A first magnetic block 15 is installed at one end of the connecting rod 12 extending along the liquid level monitoring frame 11, and the first magnetic block 15 can approach the first magnetic sensor 131 and the second magnetic sensor 141 when moving along with the connecting rod 12.

The rack 16 is arranged in the box body in a sliding mode, a groove can be integrally formed in the box body in a stamping mode, the rack 16 is arranged in the groove and moves up and down under the driving of the first gear 133 or the second gear 143, the lower end of the rack 16 is fixedly provided with the intercepting ring 17, the intercepting ring 17 is annular, the intercepting speed of water flow in the pipeline can be limited when the rack extends into the pipeline, and the intercepting speed of water flow in the pipeline cannot be limited when the rack retracts out of the pipeline.

When the specific work is performed, when the first magnetic sensor 131 senses that the magnetic field of the first magnetic block 15 is greater than the preset threshold, the first motor 132 drives the first gear 133 to drive the rack 16 to move downwards, so that the rack 16 drives the cutoff ring 17 at the lower end of the rack to extend into the pipeline, and thereby the cutoff speed limit of the liquid flowing in the pipeline is realized.

When the second magnetic sensor 141 senses that the magnetic field of the first magnetic block 15 is greater than a preset threshold, the second motor 142 drives the second gear 143 to drive the rack 16 to move upward, so that the rack 16 drives the cutoff ring 17 at the lower end of the rack to retract into the pipeline, and thus, the flow in the pipeline is not cut off and limited.

Specifically, the water flow in the pipeline is explained, when the pipeline is in a non-leakage state, as shown in fig. 1, the water flow in the pipeline is slow, at this time, the buoyancy ball 121 rises under the buoyancy of the water, so that the buoyancy ball 121 pushes the connecting rod 12 to move upwards, the first magnetic block 15 on the connecting rod 12 is higher than the first magnetic sensor 131, and at this time, the first motor 132 and the second motor 142 do not work; as shown in fig. 2, when water flow in the pipeline leaks, the water flow in the pipeline needs to be reduced continuously, at this time, the buoyancy ball 121 descends under the buoyancy action of water, so that the buoyancy ball 121 moves the connecting rod 12 downwards, the first magnetic block 15 on the connecting rod 12 is close to the first magnetic sensor 131, when the magnetic field of the first magnetic block 15 sensed by the first magnetic sensor 131 is greater than a preset threshold value, it is determined that the pipeline leaks at this time, the first driving motor detects the signal to drive the first gear 133 to drive the rack 16 to move downwards, and the rack 16 drives the intercepting ring 17 to perform intercepting speed limiting on the pipeline.

After the pipeline is repaired, because the whole pipeline is continuously filled with water flow in the pipeline, the buoyancy ball 121 rises under the buoyancy action of water, so that the connecting rod 12 is moved upwards by the buoyancy ball 121, the first magnetic block 15 on the connecting rod 12 is close to the second magnetic sensor 141, when the magnetic force of the first magnetic block 15 sensed by the second magnetic sensor 141 is greater than a preset threshold value, the pipeline is judged to be free of leakage, the second driving motor detects the signal to drive the second gear 143 to drive the rack 16 to move upwards, and the rack 16 drives the intercepting ring 17 to move upwards to not carry out intercepting speed limiting on the pipeline.

In order to realize the above working principle and function, the first motor 132 and the second motor 142 do not work at the same time, that is, when the first motor 132 works, the second motor 142 does not work; when the second motor 142 is operated, the second motor 142 does not operate; also, the driving directions of the first motor 132 and the second motor 142 are different.

Further, as shown in fig. 5, the first magnetic sensor 131 and the second magnetic sensor 141 include a magnetic coil 1311 disposed therein, when the first magnetic block 15 and the magnetic coil 1311 are close to each other, the magnetic coil 1311 may sense a magnetic field of the first magnetic block 15, the magnetic coil 1311 transmits the sensed magnetic field to the controller 1312, and the controller 1312 compares a detected magnetic field signal with a preset threshold value, thereby controlling the corresponding driving motor to operate.

Further, be equipped with liquid level height dimension on the liquid level monitoring frame 11, through the liquid level height dimension set up the predetermined threshold value in the above-mentioned controller 1312, should predetermine the threshold value and can change according to actual conditions, this moment adjust first drive assembly and second drive assembly's position can, realize the different liquid level monitoring to liquid level monitoring, improve this cut-off equipment's range of application.
