Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and in particular to an integrated device for groundwater intelligent dynamic monitoring and pressure relief control. Background Art

[0002] In the field of water conservancy projects, effective monitoring and reasonable control of groundwater are crucial to ensure the safety and stable operation of the project. With the acceleration of urbanization and the continuous advancement of infrastructure construction, more and more water conservancy projects are facing the challenge of groundwater problems.

[0003] Traditional groundwater monitoring methods often rely on manual regular testing, which is not only inefficient but also unable to obtain real-time information on the dynamic changes of groundwater. For example, in some large-scale water conservancy projects, manual monitoring is difficult to fully cover due to the wide range of areas involved, resulting in untimely grasp of changes in key parameters such as groundwater level and water quality, and failure to detect potential safety hazards in a timely manner.

[0004] In terms of groundwater pressure relief control, existing devices are usually simple in structure, single in function, and lack intelligent control methods. Some pressure relief valves rely solely on water pressure to control opening and closing, and cannot be accurately adjusted according to multiple factors such as groundwater quality and flow rate. This may cause impurities to easily clog the pressure relief valve when the water quality is poor, affecting its normal operation; or when the flow rate is too large or too small, the pressure relief volume cannot be adjusted in time, causing unnecessary pressure on the structure of the water conservancy project and threatening the stability of the project.

[0005] In addition, existing groundwater monitoring and pressure relief control devices are often independent of each other and do not form an integrated system. This makes it impossible to timely feed back monitoring data to the pressure relief control link, resulting in a disconnect between monitoring and control and an inability to achieve efficient management of groundwater.

[0006] It can be seen that the following problems exist in the prior art: a) Due to the limitations of manual monitoring, the monitoring data of groundwater cannot reflect its dynamic changes in real time, and monitoring blind spots are prone to occur, resulting in delayed early warning of potential safety hazards in the project. In addition, human errors may exist in the manual detection process, affecting the accuracy of the data. b) Traditional pressure relief valves cannot comprehensively consider multiple factors for precise control, are easily affected by impurities, and cannot flexibly adjust the pressure relief strategy according to actual conditions, which has limited protection effects on water conservancy projects. c) Measurement and pressure relief control are independent of each other, and information cannot be shared and processed collaboratively, making it difficult to achieve comprehensive and effective management of groundwater, reducing the ability of water conservancy projects to deal with groundwater problems. Summary of the invention

[0007] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide an integrated device for intelligent dynamic monitoring and pressure relief control of groundwater, which solves the technical problems of inaccurate and non-real-time groundwater monitoring, lack of intelligent precision in pressure relief control, and non-integration of monitoring and control in water conservancy projects, realizes real-time and accurate monitoring of groundwater, intelligent and precise pressure relief control, and integrated collaborative management of monitoring and control, and effectively improves the ability of water conservancy projects to cope with groundwater problems and operational safety.

[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0031] Embodiment 1

[0032] As Figure 1 shown, the present invention provides an integrated device for intelligent dynamic monitoring and pressure relief control of groundwater, which is composed of a valve body 1, a valve core 4, a dynamic monitoring unit, a driving unit, and a control unit. A fluid passage is formed between the valve body 1 and the valve core 4. Groundwater flows in through the water inlet end 2 on the side of the valve body 1 away from the valve core 4, and flows out from the water outlet end 17 on the side close to the valve core 4 after passing through the fluid passage.

[0033] Specifically, the dynamic monitoring unit is integrated on the fluid passage, including a water quality sensor 21 symmetrically installed on both sides of the inner wall of the water inlet end 2 and a flow sensor 18 symmetrically installed on both sides of the inner wall of the water outlet end 17. The water quality sensor 21 is used to monitor water quality conditions such as the acidity and alkalinity, dissolved matter content, total ion concentration in water, and turbidity of groundwater. The flow sensor 18 adopts the ultrasonic measurement principle to real-time monitor the water outlet flow of the device. Below the water quality sensor 21, there is a filter screen 3, the two ends of which are fixedly connected to both ends of the inner wall of the valve body 1, and is made of corrosion-resistant material, which is used to screen the inflowing groundwater, intercept impurities in the water, and protect the water quality sensor 21 and other components of the device.

[0034] The drive unit includes a movable rod 6 and a sleeve 14. The movable rod 6 is sleeved inside the sleeve 14, and one end of it is fixedly connected to the valve core 4. A telescopic spring 7 is provided between the movable rod 6 and the sleeve 14. One end of the telescopic spring 7 is fixedly connected to the other end of the movable rod 6, and the other end is connected to a guide post 8. Under the elastic action of the telescopic spring 7, the guide post 8 provides a stable elastic force for the reset of the valve core 4. The other end of the guide post 8 is fixedly connected to a cover plate 9 with an arc structure. An L-shaped fixing bracket 15 is installed on the outer wall of the movable rod 6. Its horizontal end is fixed to the movable rod 6, and a slide rail 16 is arranged on the vertical end. The slide rail 16 is slidably connected to the fixing bracket 15, and one end of the slide rail 16 is fixed to the outer wall of the control unit, providing guidance and support for the movement of the movable rod 6.

[0035] The control unit includes an electromagnetic coil 12, a controller 10, a power module 19, and a signal processing module 20. The output end of the controller 10 is connected to the electromagnetic coil 12, which is used to control the energized or de-energized state of the electromagnetic coil 12. Protective covers 11 are provided at both ends of the controller 10. The bottom of the protective cover 11 is fixedly connected to a baffle 13. The guide post 8 passes through the middle of the baffle 13 to ensure the longitudinal movement of the guide post 8. The power module 19 and the signal processing module 20 are both arranged inside the valve body 1. The power module 19 selects a lithium battery. Refer to Figure 2 , the power module 19 is electrically connected to the controller 10, the water quality sensor 21, the flow sensor 18, and the signal processing module 20 respectively to provide electrical energy for each component of the device. At the same time, the monitoring signals of the water quality sensor 21 and the flow sensor 18 are wirelessly transmitted to the signal processing module 20, and the signals of the signal processing module 20 are wirelessly transmitted to the controller 10.

[0036] Refer to Figure 3, the signal processing module 20 includes a signal receiving group 22, a signal evaluation group 23, and a wireless transmitting group 24. The signal receiving group 22 is used to receive the monitoring data of the water quality sensor 21 and the flow sensor 18. The signal evaluation group 23 compares the received data with a preset threshold. When the groundwater quality data detected by the water quality sensor 21, such as pH value, dissolved matter content, total ion concentration in water, turbidity, etc., exceeds the allowable threshold set according to the water quality requirements of different projects, the wireless transmitting group 24 is enabled. The wireless transmitting group 24 uses one of Bluetooth, Wi-Fi, and LoRa to transmit a wireless signal to the controller 10. The controller 10 controls the electromagnetic coil 12 to be energized or de-energized according to the signal. At the same time, the controller 10 also issues an instruction to automatically close the device to prevent the polluted groundwater from being discharged into the channel or reservoir and affecting its water quality, thereby realizing the control of the opening and closing state of the valve core 4. When the device is applied to scenarios where the monitoring points are relatively concentrated, close to the control terminal (usually within 100 meters), and have high requirements for real-time performance, the wireless transmitting group selects the Bluetooth communication method, which has the characteristics of low power consumption and high-speed short-distance transmission. The transmission distance is usually 10 - 100 meters in an open space, and the transmission rate can reach 1 Mbps - 2 Mbps. When the monitoring points are distributed within a certain area (a few kilometers), and there are not high requirements for the data transmission rate, but a communication method with better penetration and lower cost is needed, LoRa is selected. Its transmission distance can reach several kilometers in an open area, generally 2 - 5 kilometers, and the transmission rate is between 0.3 kbps - 50 kbps. If the device is in an area covered by a Wi-Fi network and a large amount of data needs to be transmitted, Wi-Fi communication is used, which has the advantages of high bandwidth and high-speed transmission, and the transmission rate can reach 11 Mbps - 1000 Mbps or more.

[0037] In addition, limiting parts 25 are symmetrically arranged at both ends of the valve body 1 and are integrally formed with the valve body 1 to limit the displacement of the valve body 1. A groove is formed in the inner wall of the valve body 1, and rubber pads 5 connected to both ends of the valve core 4 are embedded in the groove to enhance the sealing performance between the valve core 4 and the valve body 1. A sealing gasket 26 is arranged at the contact position between the top of the valve body 1 and the inner side of the cover plate 9 to ensure the overall sealing performance of the device in the closed state of the valve core 4.

[0038] In addition, due to the coordinated use of the driving unit and the control unit, the working principle of the device is as follows:

[0039] First, the signal processing module 20 in the control unit is responsible for collecting the data acquired by the flow sensor 18 and the water quality sensor 21. After the signal receiving group 22 receives this data, it transmits it to the signal evaluation group 23. The signal evaluation group 23 compares the received monitoring data with the preset threshold. For example, when the water quality sensor 21 detects abnormal groundwater pH value or excessive dissolved matter content, or when the flow sensor 18 monitors that the effluent flow rate is too large or too small, the signal evaluation group 23 determines that the monitoring data exceeds the normal range and triggers the wireless transmission group 24. The wireless transmission group 24 sends a signal to the controller 10 through wireless communication methods such as Bluetooth, Wi-Fi, LoRa, etc. After receiving the signal, the controller 10 generates corresponding control instructions according to the preset control logic. Since the output end of the controller 10 is connected to the electromagnetic coil 12, the generated control instructions are transmitted to the electromagnetic coil 12 in the form of electrical signals. This instruction is used to control the energized or de-energized state of the electromagnetic coil 12, and thus determine whether a magnetic field is generated and the intensity of the magnetic field.

[0040] When the electromagnetic coil 12 is energized, a magnetic field is generated. Under the action of the magnetic field, the telescopic spring 7 contracts under the suction force, and then drives the movable rod 6 to perform axial movement. Since the movable rod 6 is sleeved inside the sleeve 14 and is fixedly connected to the valve core 4 at one end. When the electromagnetic force overcomes the elastic force of the telescopic spring 7, the movable rod 6 will move along the axial direction of the sleeve 14. At the same time, the fixed frame 15 slides on the slide rail 16, and then drives the valve core 4 and the cover plate 9 to open simultaneously, so that the fluid channel in the valve body 1 is opened, and the groundwater can flow from the water inlet end 2 to the water outlet end 17, realizing the pressure relief function. When the electromagnetic coil 12 is de-energized, the magnetic field disappears, and the electromagnetic force also disappears. At this time, the telescopic spring 7 begins to play a role. One end of the telescopic spring 7 is connected to the movable rod 6, and the other end is connected to the guide post 8, and the guide post 8 is fixed on the cover plate 9. Under the action of the elastic restoring force of the telescopic spring 7, the movable rod 6 is pulled back to the initial position, driving the valve core 4 and the cover plate 9 to close simultaneously, and the fluid channel is closed accordingly, stopping the pressure relief. During the movement of the movable rod 6, the fixed frame 15 on its outer wall cooperates with the slide rail 16 to provide guidance and support for the movement of the movable rod 6, ensuring that the movable rod 6 moves reciprocally stably and ensuring the accurate and reliable opening and closing actions of the valve core 4.

[0041] Moreover, throughout the process, the control unit continuously receives data from the dynamic monitoring unit and adjusts the control of the driving unit in real time according to the data changes. If the monitored data remains abnormal, the controller 10 will continuously send a power-on signal to the electromagnetic coil 12 to keep the valve core 4 open for continuous pressure relief; if the monitored data returns to normal, the controller 10 will control the electromagnetic coil 12 to cut off the power and close the valve core 4. At the same time, in terms of water quality monitoring, once the water quality returns to normal and meets the requirements of the project for water quality, the controller 10 will control the device to resume the open state and restore the normal drainage process. Through the close cooperation of the driving unit and the control unit, the device can automatically and accurately control the opening and closing state of the valve core 4 according to the actual situation of the groundwater.

[0042] Therefore, by adopting the above-mentioned integrated device for intelligent dynamic monitoring and pressure relief control of groundwater, the technical problems of inaccurate and untimely groundwater monitoring, lack of intelligent precision in pressure relief control, and non-integration of monitoring and control in water conservancy projects are solved. The real-time and accurate monitoring of groundwater, intelligent and precise pressure relief control, and integrated collaborative management of monitoring and control are realized, effectively improving the ability of water conservancy projects to cope with groundwater problems and operation safety.

[0043] In this article, specific examples are used to elaborate on the principles and implementation methods of the present invention. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
