Description

Technical Field

[0001] The present invention relates to the technical field of men's sanitary circles, and specifically to an automatic emptying system for pipeline detection. Background Art

[0002] Pipeline detection is an important link to ensure the safe and effective operation of pipeline systems. It involves the process of evaluating the physical condition, performance, and potential problems of pipelines. Pipeline detection can be applied to various types of pipeline systems, including but not limited to water supply pipelines, drainage pipelines, oil and gas transportation pipelines, and industrial pipelines, etc. During winter use, due to the low temperature, the water inside the pipeline is easily affected by the temperature and freezes. Freezing can cause cracks and damage to the pipeline.

[0003] Currently, after pipeline detection, the water inside the pipeline is controlled to drain by closing the water inlet valve of the pipeline. This method will cause residual water in the pipeline and low drainage efficiency.

[0004] Therefore, in order to correct the above defects, we propose an automatic emptying system for pipeline detection. Summary of the Invention

[0005] The technical problem solved by the present invention is to propose an automatic emptying system for pipeline detection.

[0006] To achieve the above object, the present invention provides the following technical solution: An automatic emptying system for pipeline detection, including a data acquisition module, a data processing module, and a valve control module. The data acquisition module collects the temperature and pressure inside the pipeline to be detected and feeds the collected data back to the data processing module. The data processing module feeds the signal back to the valve control module. The valve control module is connected to different valves on the pipeline. The valve control module controls the opening or closing of different valves according to the signal to empty the pipeline.

[0007] The data acquisition module includes a temperature sensor and a pipeline internal pressure sensor.

[0008] Further, the data acquisition module further includes two pneumatic three-way valves. The two pneumatic three-way valves are installed by intercepting a section on the pipeline to be detected. A replacement pipeline parallel to the pipeline to be detected is also connected between the two pneumatic three-way valves. The temperature sensor and the pipeline internal pressure sensor are installed inside the replacement pipeline. The two pneumatic three-way valves are respectively connected to the valve control module.

[0009] Further, a same-diameter pipe is installed by intercepting a section on the replacement pipeline. The temperature sensor and the pipeline internal pressure sensor are installed inside the same-diameter pipe.

[0010] Further, both ends of the same-diameter pipe are connected to the replacement pipeline through flanges.

[0011] Further, the alternative pipeline is installed in the direction of the inlet end of the alternative pipeline.

[0012] Further, the venting system further includes a water storage well, an inlet pipeline and a return pipeline are connected to the water storage well. When the pipeline to be detected is vented, the water in the pipeline to be detected is introduced into the water storage well through the inlet pipeline, and at the same time, it flows back into the pipeline to be detected through the return pipeline.

[0013] Further, an electromagnetic three-way valve 1 is installed at the short outlet of the alternative pipeline. One port of the electromagnetic three-way valve 1 is connected to a water diversion pipe, and the other end of the water diversion pipe is connected to an electromagnetic three-way valve 2. The other two ports of the electromagnetic three-way valve 2 are respectively connected to the inlet pipeline and the return pipeline.

[0014] Further, a water pump is installed at the outlet end of the inlet pipeline, and the inlet end of the return pipeline extends to the bottom of the water storage well. At the same time, a water pump is also installed at the inlet end of the return pipeline.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The system in the present invention can detect the temperature and pressure in the pipeline through temperature sensors, pressure sensors, etc., and then automatically drain the water in the pipeline, and at the same time, it can also achieve automatic water return.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a technical solution:

[0021] Please refer to Figure 1, An automatic emptying system for pipeline detection, including a data acquisition module, a data processing module, and a valve control module. The data acquisition module collects the temperature and pressure inside the pipeline to be detected, and feeds the collected data back to the data processing module. The data processing module feeds the signal back to the valve control module. The valve control module is connected to different valves on the pipeline, and the valve control module controls the opening or closing of different valves according to the signal to perform the emptying process on the pipeline;

[0022] The data acquisition module includes a temperature sensor and a pipeline internal pressure sensor;

[0023] When the temperature sensor and the pipeline internal pressure sensor detect that the temperature and pressure inside the pipeline are relatively low, they transmit the data signal to the data processing module, and the data processing module then transmits the signal to the valve control module to perform the valve operation, such as closing the valve on the inlet of the pipeline to be detected, and using a water pump or the like to pump the water inside the pipeline into the water storage well 8.

[0024] Considering that directly adding a detection device inside the pipeline to be detected will affect the normal water flow inside the pipeline after a long time, a parallel alternative pipeline is added outside the pipeline to be detected to detect the temperature and pressure. Specifically:

[0025] The data acquisition module further includes two pneumatic three-way valves 1. The two pneumatic three-way valves 1 are installed by intercepting a section on the pipeline to be detected. A parallel alternative pipeline 2 to the pipeline to be detected is also connected between the two pneumatic three-way valves 1. The temperature sensor and the pipeline internal pressure sensor are installed inside the alternative pipeline 2. The two pneumatic three-way valves 1 are respectively connected to the valve control module. That is, two pneumatic three-way valves 1 are inserted into the pipeline to be detected. When it is necessary to detect the temperature and pressure inside the pipeline, the valve plate of the valve port where the pneumatic three-way valve 1 in the inlet direction is connected to the inlet end of the alternative pipeline 2 is opened, while the other valve plate is closed. The valve plate of the valve port where the other pneumatic three-way valve 1 is connected to the outlet end of the alternative pipeline 2 is opened, while the other valve plate is closed. In this way, the water will bypass and enter the alternative pipeline 2, and the alternative pipeline 2 will form an interconnection with the part in the inlet end direction and the part in the outlet end direction of the pipeline to be detected through the two pneumatic three-way valves 1. The temperature sensor and the pipeline internal pressure sensor detect that the temperature data and pressure data inside the alternative pipeline 2 are equivalent to the temperature data and pressure data inside the pipeline to be detected. When emptying is not required, the two pneumatic three-way valves 1 are reset, and no water enters the alternative pipeline 2.

[0026] Considering that the temperature sensor and the in-pipe pressure sensor will scale in the pipeline in the long term, affecting the accuracy of the measurement data. Therefore, the temperature sensor and the in-pipe pressure sensor need to be removable for replacement. For this purpose: Instead of cutting a section on pipeline 2 and installing a pipe of the same diameter 3, the temperature sensor and the in-pipe pressure sensor are installed inside the pipe of the same diameter 3. The two ends of the pipe of the same diameter 3 are respectively flange-connected to the replacement pipeline 2. That is, after removing the pipe of the same diameter 3, the temperature sensor and the in-pipe pressure sensor can be maintained.

[0027] The replacement pipeline 2 is installed in the direction of the inlet end of the replacement pipeline 2.

[0028] The emptying system further includes a water storage well 8. An inlet pipeline 7 and a return pipeline are connected to the water storage well 8. When the pipeline to be detected is emptied, the water in the pipeline to be detected is introduced into the water storage well 8 through the inlet pipeline 7, and at the same time, it flows back into the pipeline to be detected through the return pipeline. On the replacement pipeline 2, an electromagnetic three-way valve 4 is installed at the short outlet. One port of the electromagnetic three-way valve 4 is connected to a water diversion pipe 5. The other end of the water diversion pipe 5 is connected to an electromagnetic three-way valve 6. The other two ports of the electromagnetic three-way valve 6 are respectively connected to the inlet pipeline 7 and the return pipeline. A water pump is installed at the outlet end of the inlet pipeline 7. The inlet end of the return pipeline extends to the bottom of the water storage well 8, and a water pump is also installed at the inlet end of the return pipeline.

[0029] That is, during the emptying process, close all the valve plates of the pneumatic three-way valve 1 at the inlet end of the replacement pipeline 2 and the valve at the outlet end of the pipeline to be detected, and at the same time, close the valve plate of the port of the electromagnetic three-way valve 6 connected to the return pipeline. Then the water in the pipeline to be detected and the replacement pipeline 2 enters the water storage well. When it will not freeze, the water in the water storage well 8 can be returned to the pipeline to be detected, that is, open the valve plate of the port of the electromagnetic three-way valve 6 connected to the return pipeline, close the valve plate of the port of the electromagnetic three-way valve 6 connected to the inlet pipeline 7, and at the same time, close the valve plate of the port of the electromagnetic three-way valve 4 facing the inlet end of the replacement pipeline 2, so that the water in the water storage well 8 enters the pipeline to be detected through the water diversion pipe 5.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
