Description

Technical Field

[0001] This application relates to the technical field of energy station management, and in particular to a cold and heat storage pipeline management device for energy stations. Background Technology

[0002] A heating room is a type of energy station, an equipment room used to provide heating to the heating area. A heating room generally includes water supply units, water pumps, boiler units, water treatment dosing devices, water collectors, water distributors, and various electrical control components. In order to provide heating to the heating area, fluids need to be transported through pipelines. After being pressurized and heated by blowers, compressors, pumps, and boilers, the fluids flow from the high-pressure area to the low-pressure area in the pipelines. Alternatively, the fluids can be transported using their own pressure or gravity.

[0003] However, during long-term use, pipe walls may break due to aging, collisions, or other factors, resulting in a large amount of fluid spilling out. If this is not dealt with in time, it will cause energy loss. Therefore, we need to propose a cold and heat storage pipeline management device for energy stations. Utility Model Content

[0010] The control module is connected to the water pressure monitoring module, the pipeline control module, and the leak sealing module respectively. By receiving the monitoring signal from the water pressure monitoring module, it controls the pipeline control module to switch the pipeline and the leak sealing module to seal the leak.

[0011] As a preferred technical solution of this application, the water pressure monitoring module includes a pressure sensor connected to the pipeline and a video camera installed in the energy station. The pressure sensor is connected to the control module and transmits pressure signals to the control module.

[0018] 1. In this application, a water pressure monitoring module is used to monitor the pressure of the cold and heat storage pipelines in the energy station. Based on the pressure changes, it is determined whether the pipeline has been damaged. The leak point is identified by a video camera.

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0024] Example: This application proposes a cold and heat storage pipeline management device for energy stations, referring to... Figure 1-2 The device includes a water pressure monitoring module 1, a pipeline control module 2, a leak sealing module 3, and a control module 4. The water pressure monitoring module 1 monitors pipeline pressure and identifies leak points. The pipeline control module 2, based on the identified leak, controls the switching of the fluid flow path through the pipeline. The leak sealing module 3, based on the identified leak location, moves to the leak point and seals it. The control module 4 can be a PLC controller to control the operation of the entire device. In this embodiment, an alarm device can be connected to the control module 4. When a pipeline leak occurs, the alarm device can sound an alarm to alert on-duty personnel.

[0025] This embodiment explains the application of the device on a straight pipe. The water pressure monitoring module 1 includes a pressure sensor 11 and a video camera 12. The pressure sensor 11 is installed on the pipe, and multiple sensors can be set according to the pipe length, with one sensor installed every five meters. The pressure sensor 11 is electrically connected to the control module 4. The pressure sensor 11 collects the fluid pressure in the pipe in real time and sends the pressure data to the control module 4 in the form of a data signal. The control module 4 monitors the pressure changes in the pipe in real time. The video camera 12 is installed in the energy station and can monitor the entire target pipe, making it convenient for on-duty personnel to detect leaks in a timely manner.

[0026] The pipeline control module 2 includes a backup pipeline 21 and a control valve group. The backup pipeline 21 is connected in parallel with the target pipeline. The control valve group is installed at the ends of the backup pipeline 21 and the target pipeline. In this embodiment, the control valve group is equipped with two electromagnetic three-way valves 22. The two inlets of the electromagnetic three-way valves 22 are respectively connected to the backup pipeline 21 and the target pipeline, realizing the switching between the state of the backup pipeline 21 being open and the state of the target pipeline being open. The two electromagnetic three-way valves 22 are electrically connected to the control module 4. The control module 4 issues a control command to the electromagnetic three-way valves 22 according to the determined leakage situation. The electromagnetic three-way valves 22 close the target pipeline and open the backup pipeline 21, so that the fluid can continue to flow in the circulation system of the entire energy station, avoiding the problem of energy station shutdown caused by leakage in the target pipeline.

[0027] The leak sealing module 3 is set parallel to the target pipeline and connected to it. The leak sealing module 3 can move relative to the target pipeline and to the leak point to seal it. The leak sealing module 3 includes a traveling track 31 and a sealing vehicle. The traveling track 31 is set parallel to the target pipeline, and the sealing vehicle is movably mounted on the traveling track 31, allowing it to move relative to the target pipeline to reach the leak point and seal it.

[0028] In this embodiment, the walking track 31 is set as a transmission chain with the same direction as the target pipeline. The drive wheel of the transmission chain is connected to a drive motor 32 to drive the transmission chain to rotate. In specific implementation, a single transmission chain or multiple transmission chains can be set on the target pipeline. The drive motor 32 is electrically connected to the control module 4, and the control module 4 controls the start and stop of the rotation and the direction of rotation of the drive motor 32. In this embodiment, the leak-sealing vehicle is fixedly connected to the transmission chain and moves together with the transmission chain.

[0029] The leak-sealing vehicle includes a fixed base 33, a pipe collar 34, a sealing airbag 35, and an air pump 36. The fixed base 33 has a split structure, with the two parts fixedly mounted on the drive chain by bolts. The fixed base 33 is always located on the side of the drive chain closest to the target pipe. The pipe collar 34 is circular and fixedly mounted on the fixed base 33, and coaxially sleeved on the target pipe. The sealing airbag 35 is an annular airbag installed on the inner ring of the pipe collar 34. The air pump 36 is installed on the outer ring of the pipe collar 34 and is connected to the sealing airbag 35 through a pipe. The air pump 36 inflates the sealing airbag 35. The air pump 36 is electrically connected to the control module 4, which controls the start and stop of the air pump 36. After the sealing airbag 35 is inflated, it will squeeze the outer wall of the target pipe and seal the damaged and leaking parts of the target pipe.

[0030] The implementation principle of this application embodiment is as follows: A pressure sensor 11 and a video camera 12 monitor the pipelines within the energy station. When a leak occurs in the target pipeline, the pressure sensor 11 senses a significant change in pressure within the pipeline and sends a signal to the control module 4. The control module 4 determines whether a pipeline leak has occurred according to a pre-set program. If a leak occurs, an alarm device is activated to send an alarm to the monitoring personnel. The monitoring personnel observe the scene using the video camera 12, determine the leak situation and location, and control the electromagnetic tri-channel system via the control module 4. The valve 22 changes the direction of the connecting pipe, closes the target pipe, and starts the direction of the backup pipe 21 to reduce the leakage of fluid at the leak point. At the same time, the drive motor 32 on the drive wheel of the transmission chain is started to control the leak-sealing vehicle to move to the leak point. Then, the air pump 36 inflates the sealing airbag 35. After inflation, the sealing airbag 35 will fully expand and stick to the leak point of the target pipe to prevent the fluid at the leak point from continuing to flow out. Since the target pipe has been closed, the internal pressure is reduced, making it difficult to break open the sealing airbag 35, so that the leakage is controlled and it is convenient for maintenance personnel to carry out subsequent maintenance.

[0031] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
