[0027] With the development of industrial automation and intelligence, the safety and efficiency of hydropower stations, as one of the important renewable energy sources, have received extensive attention. During the operation of hydropower stations, flood discharge is an important link to ensure the safety of dams and related facilities. At present, traditional hydropower station flood discharge control usually relies on manual monitoring and operation.

[0028] However, the manual monitoring method not only has the problem of untimely response, but is also easily affected by human factors, resulting in low actual monitoring efficiency. In addition, the control response speeds of gates in different locations are different, and the manual monitoring method is difficult to adapt to the complex and changeable on-site environment.

[0029] In order to solve this technical problem, the present invention proposes a flood discharge monitoring device for a hydropower station reservoir.

[0030] See also Figure 1 , Figure 2 and Figure 5 In one embodiment of the present invention, a flood discharge monitoring device for a hydropower station reservoir is provided. The hydropower station reservoir comprises a breast wall 10 and a gate 20. The gate 20 is arranged below the breast wall 10. The gate 20 is connected to a hoist 30. The flood discharge monitoring device for a hydropower station reservoir comprises a clamping assembly 100, a base 200, a monitoring mechanism 300 and a control module 400. The clamping assembly 100 is clamped on the top of the breast wall 10. The base 200 is slidably arranged on the clamping assembly 100 in a vertical direction. The base 200 and the gate 20 are connected to each other. The monitoring mechanism 300 is arranged at an interval; the monitoring mechanism 300 is arranged on the side of the base 200 facing the gate 20, and the monitoring mechanism 300 can rotate around the base 200 between an initial position close to the breast wall 10 and a debugging position away from the breast wall 10, and the monitoring mechanism 300 is used to monitor the position of the gate 20 to obtain the opening degree of the gate 20; the monitoring mechanism 300 and the gate hoist 30 are both electrically connected to the control module 400, and the control module 400 is used to control the gate hoist 30 according to the opening degree of the gate 20 and the flood discharge.

[0031] It should be noted that the monitoring mechanism 300 is an ultrasonic sensor, a radar sensor or a laser sensor in the related technology.

[0032] Specifically, a flood discharge monitoring device for a hydropower station reservoir is proposed. The device is aimed at the demand for accurate control of flood discharge during the operation of the hydropower station to improve safety and operation efficiency. The hydropower station reservoir structure includes a breast wall 10 and a gate 20 located below the breast wall 10. The gate 20 is operated by a hoist 30 to ensure the smooth progress of the flood discharge operation.

[0033] First, the clamping assembly 100 is fixed to the top of the breast wall 10. The clamping assembly 100 provides a stable foundation that can firmly support the base 200 and avoid the problem of instability of the monitoring device due to water flow impact or other external interference. The clamping assembly 100 can effectively assist other components in performing stable and accurate monitoring tasks.

[0034] The base 200 can slide vertically in the clamping assembly 100 to maintain an appropriate distance from the gate 20. The base 200 can flexibly adjust its position to meet the monitoring needs in different environments, ensuring that the monitoring mechanism 300 can always be located at a position with the best field of view. Through the adjustable base 200, the monitoring mechanism 300 can obtain accurate data and reduce errors caused by environmental factors.

[0035] The monitoring mechanism 300 is arranged on one side of the base 200, facing the gate 20, and can rotate between positions close to or far from the breast wall 10. This rotation capability enables the monitoring mechanism 300 to perform monitoring work at different angles. After adjusting the angle, it is ensured that the monitoring mechanism 300 can accurately capture the real-time opening and closing information of the gate 20. The opening degree of the gate 20 directly affects the flood discharge. Through real-time monitoring, the system can respond quickly and adjust the control strategy.

[0036] Finally, the monitoring mechanism 300 and the gate hoist 30 are both electrically connected to the control module 400. The control module 400 makes a comprehensive calculation based on the opening degree of the gate 20 and the flood discharge volume, and issues a command to the gate hoist 30 to accurately adjust the opening degree of the gate 20 to realize the automation of flood discharge control. This not only improves the response speed, but also reduces the risk of improper human operation.

[0037] In the technical solution provided by the present invention, a clamping assembly 100 is arranged on the top of the breast wall 10, and a base 200 is arranged vertically and slidably thereon, and the base 200 is spaced apart from the gate 20, thereby ensuring that the monitoring mechanism 300 can be stably installed on the base 200. The monitoring mechanism 300 can rotate around the base 200, and can be flexibly adjusted between the initial position close to the breast wall 10 and the debugging position away from the breast wall 10, so as to debug and obtain the best angle for monitoring the position of the gate 20, thereby obtaining the opening degree of the gate 20. It can effectively solve the problems of slow response and inability to adapt to complex environments of traditional manual monitoring methods, significantly improve the operational efficiency and safety of monitoring the flood discharge of the hydropower station reservoir, and provide reliable guarantee for the smooth operation of the hydropower station.

[0038] As an optional implementation of this embodiment, the flood discharge monitoring device of the hydropower station reservoir also includes a water level sensor: using an ultrasonic or pressure sensor, installed at different positions of the reservoir to monitor water level changes; and / or, a flow sensor: using an ultrasonic flowmeter or an electromagnetic flowmeter, installed in a flood discharge channel or channel to measure flow; and / or, a water flow velocity sensor: using a Doppler flowmeter, installed in a flood discharge channel or channel to monitor water flow velocity; and / or, an environmental sensor: including temperature, humidity, air pressure sensors, and possible light intensity and wind speed sensors to monitor environmental conditions. Among them, the water level sensor control module 400, the flow sensor, the water flow velocity sensor or the environmental sensor are electrically connected to the control module 400, and the control module 400 adjusts the monitoring frequency of the monitoring mechanism 300 according to the sensing signals of the water level sensor control module 400, the flow sensor, the water flow velocity sensor or the environmental sensor, so that the monitoring mechanism 300 can more quickly respond to the current flood discharge situation of the hydropower station reservoir.

[0039] For ease of understanding, a specific implementation is shown here: The clamping assembly 100 is mounted on the top of the breast wall 10 of the hydropower station. The base 200 is mounted on the clamping assembly 100 so that it can slide vertically. The height of the base 200 is preliminarily adjusted to ensure that it maintains a safe distance from the upper edge of the gate 20 to avoid physical obstacles during operation. The monitoring mechanism 300 is mounted on the base 200 so that the monitoring end 321 faces the gate 20. The rotation angle of the monitoring mechanism 300 is adjusted to determine the best monitoring position through trial operation. The monitoring mechanism 300 and the hoist 30 are connected to the control module 400 respectively. Ensure that all cables are tightly connected and waterproof to avoid the influence of harsh environment on the electrical connection. Start the control module 400 and perform initial settings, including the calibration of the gate 20 and the setting of the flood discharge monitoring benchmark. By collecting initial data, the relationship between the reading of the monitoring mechanism 300 and the actual gate 20 opening is calibrated to ensure the accuracy of the data. After startup, the control module 400 receives the gate 20 opening information sent back by the monitoring mechanism 300 in real time. According to the set flood discharge target, the control module 400 calculates the required opening of the gate 20 and sends instructions to the hoist 30 for adjustment. During the operation, the monitoring mechanism 300 continuously tracks the dynamics of the gate 20 to ensure that the opening adjustment achieves the expected effect.

[0040] More specifically, a first sensor is installed on the clamping assembly 100 to obtain the overall flood discharge volume of the flood discharge reservoir and the operating status information of each flood discharge gate 20. The information includes real-time opening and closing degree and historical flood discharge data. The first sensor is arranged in an area close to each gate 20 to capture the precise opening and closing state and the surrounding water flow conditions. The processor receives the data from the first sensor and performs flow analysis on the historical flood discharge data of each flood discharge gate 20. Through calculation, the processor obtains the flood discharge flow rate and its response speed of each gate 20 at the maximum opening and closing degree. The first impact attribute is pre-set, defined as the speed at which the gate 20 is adjusted to the maximum opening and closing degree from the received signal, and is calibrated and optimized through historical data. The processor uses multiple parameters such as the real-time gate 20 opening and closing degree, flood discharge height, etc. to calculate the current flood discharge volume, and compares the planned flood discharge volume to dynamically adjust the gate 20 opening. The monitoring mechanism 300 is configured on one side of the base 200, facing the gate 20. Through its rotation function, the monitoring mechanism 300 can work at multiple angles to collect accurate data on the activity of the gate 20. The control module 400 receives the data analysis results of the processor and commands the hoist 30 to adjust the opening of the gate 20 through an electrical connection. The instant feedback mechanism allows the control module 400 to adjust the opening of each gate 20 according to the obtained data to ensure that the required flood discharge is achieved while avoiding safety issues caused by excessive flow. At startup, the operator sets the target flood discharge, and the system starts historical data analysis and performs preliminary calibration. The opening and closing status of each gate 20 is monitored in real time, and the current flood discharge is calculated by the processor. Based on the calculation results, the control module 400 immediately adjusts the operation of the hoist 30 to ensure the accuracy and safety of the flood discharge process. The alarm system monitors potential over-flow or improper response, and once identified, immediately initiates safety protection measures to ensure the safety of downstream flow and stable operation of the equipment.

[0041] Please continue reading Figure 2 In an embodiment of the present invention, the clamping assembly 100 includes a limit rod 110, a rotating rod 120 and two counterweight seats 130. The two counterweight seats 130 are spaced apart along the thickness direction of the breast wall 10. The base 200 is slidably arranged on the counterweight seats 130 along the vertical direction. The limit rod 110 and the rotating rod 120 both extend along the thickness direction of the breast wall 10. The two counterweight seats 130 are slidably connected through the limit rod 110. The rotating rod 120 is threadedly connected to the two counterweight seats 130 respectively, and the rotating rod 120 is used to drive the two counterweight seats 130 to move closer to or away from each other along the limit rod 110.

[0042] Specifically, the clamping assembly 100 is composed of a limit rod 110, a rotating rod 120 and two counterweight seats 130 to provide flexible and stable structural support and improve the performance of the hydropower station reservoir flood discharge monitoring device under different operating conditions.

[0043] The two counterweight seats 130 are arranged at intervals along the thickness direction of the breast wall 10, ensuring that the base 200 has sufficient stability during the vertical sliding process, and also facilitating installation and adjustment. The counterweight seats 130 provide a stable support point, so that the base 200 can slide and adjust smoothly above the counterweight seats 130 to calibrate the optimal monitoring position of the monitoring mechanism 300 and achieve accurate monitoring of the gate 20.

[0044] The limit rod 110 and the rotating rod 120 both extend along the thickness direction of the breast wall 10, ensuring the compactness of the system and the convenience of operation. The limit rod 110 plays a guiding and limiting role between the two counterweight seats 130, allowing the counterweight seat 130 to slide on the rod, ensuring that the length of the clamping assembly 100 along the thickness direction of the breast wall 10 is adjustable, and has been adapted to breast walls 10 of different thicknesses, improving the adaptability of the flood discharge monitoring device of the hydropower station reservoir, and does not affect the use of the existing hydropower station reservoir structure, nor will it affect the structure of the hydropower station reservoir.

[0045] The rotating rod 120 has a dual function: it is threadedly connected to the two counterweight seats 130 respectively, and by rotating the rotating rod 120, the two counterweight seats 130 can be driven to move closer or farther along the limit rod 110. The counterweight seats 130 can be adjusted according to actual needs to optimize the clamping force and adaptability of the clamping assembly 100. This adjustment capability allows the monitoring device to easily adapt to different breast wall 10 thicknesses and installation conditions, improving the versatility and flexibility of the device. In addition, the threaded connection can also play a certain degree of self-locking function, preventing the monitoring mechanism 300 from loosening during use, thereby improving the overall reliability and adaptability of the device and effectively supporting the application of the flood discharge monitoring device in complex environments.

[0046] Please continue reading Figure 2 , and see Figure 3 In an embodiment of the present invention, the counterweight seat 130 includes a vertical rod 131 and a counterweight block 132. The counterweight block 132 is arranged at the top of the breast wall 10. The bottom of the counterweight block 132 is slidably connected to the limit rod 110, and the top of the counterweight block 132 is threadedly connected to the rotating rod 120; one end of the vertical rod 131 is connected to the counterweight block 132 to form a horizontal section 1311, and the other end of the vertical rod 131 is bent downward from the counterweight block 132 to form a vertical section 1312. The vertical section 1312 is arranged against the side wall of the breast wall 10, and the base 200 is slidably arranged on the vertical section 1312 along the vertical direction.

[0047] Specifically, the bottom of the counterweight block 132 is slidably connected to the limit rod 110. In this way, the counterweight block 132 can slide along the extension direction of the limit rod 110, thereby providing the monitoring device with the ability to adjust the overall center of gravity and position of the device, thereby improving the stability and reliability of the system operation.

[0048] The top of the counterweight block 132 is connected to the rotating rod 120 via a thread, and the relative position between the two counterweight blocks 132 is adjusted by rotating the rotating rod 120 .

[0049] In addition, one end of the vertical rod 131 is fixedly connected to the counterweight block 132 to form a horizontal section 1311, and the other end is bent downward to form a vertical section 1312. The vertical section 1312 is arranged close to the side wall of the breast wall 10 and allows the base 200 to slide on it in the vertical direction. This not only enhances the mechanical stability of the monitoring mechanism 300, but also enables the monitoring mechanism 300 to smoothly adjust its height and position according to actual needs, thereby ensuring the accuracy and reliability of monitoring.

[0050] Please continue reading Figure 2 and Figure 3 In an embodiment of the present invention, a plurality of through holes 1301 are formed on the vertical section 1312, and the plurality of through holes 1301 are arranged at intervals in the vertical direction, and each through hole 1301 extends along the width direction of the vertical section 1312; a plurality of insertion holes 201 are formed on the side wall of the base 200, and the insertion holes 201 are detachably connected to the through holes 1301 through the latch 500.

[0051] Specifically, the through hole 1301 on the vertical section 1312 provides more position options and operational convenience for the vertical sliding and fixing of the base 200, further improving the adaptability of the monitoring mechanism 300 in different application scenarios.

[0052] The side wall of the base 200 is provided with a plurality of plug holes 201, which are aligned with the through holes 1301 of the vertical section 1312, and the plug holes 201 are detachably connected with the through holes 1301 through the latch 500, so that the user can quickly adjust and lock the position of the base 200 on the vertical section 1312. The detachable connection mode not only provides great convenience for installation and maintenance, but also ensures the safety and stability of the monitoring mechanism 300 during operation.

[0053] More specifically, the user can select a suitable combination of through hole 1301 and jack 201 according to actual needs, lock the position of base 200, and thus realize precise adjustment of monitoring height, which greatly improves the efficiency and monitoring accuracy of the device in actual use.

[0054] Please continue reading Figure 2 and Figure 3 In an embodiment of the present invention, the outer walls of the vertical section 1312 and the horizontal section 1311 are both recessed inward to form a wire groove 1302, and the base 200 is slidably installed vertically on the side of the vertical section 1312 away from the breast wall 10, and a wire hole 202 is formed on the side of the base 200 away from the vertical section 1312, and the wire hole 202 is connected to the wire groove 1302.

[0055] Specifically, the outer walls of the vertical section 1312 and the horizontal section 1311 are recessed inward to form a wire groove 1302 , which provides a hidden and protected path for the wiring of the monitoring mechanism 300 , thereby improving the safety of the monitoring mechanism 300 .

[0056] The cable trough 1302 is arranged along the outer wall of the vertical section 1312 and the horizontal section 1311, which can effectively guide and fix the cables to prevent the cables from being damaged during use. The cable trough 1302 can arrange the cables neatly, avoid the phenomenon of tangling and confusion, improve the neatness of the wiring, and also reduce the physical damage of the environment to the cables.

[0057] A wire hole 202 is provided on one side of the base 200 away from the vertical section 1312, and the wire hole 202 is directly connected to the wire groove 1302. The cable of the control module 400 is introduced into the base 200 from the wire groove 1302, and enters the monitoring mechanism 300 in the base 200 through the wire hole 202 to be connected.

[0058] Please continue reading Figure 2 and Figure 3 , and see Figure 4 In an embodiment of the present invention, the base 200 includes a slider 210, a rotating shaft 220 and two ear plates 230. The slider 210 is slidably arranged on the clamping assembly 100 in the vertical direction. The two ear plates 230 are spaced apart along the length direction of the breast wall 10 on the side of the slider 210 facing the gate 20. The rotating shaft 220 extends along the length direction of the breast wall 10. The rotating shaft 220 passes through the two ear plates 230 and is threadedly connected with the two ear plates 230. The monitoring mechanism 300 is installed on the rotating shaft 220, and the monitoring mechanism 300 can rotate around the rotating shaft 220 between an initial position close to the breast wall 10 and a debugging position away from the breast wall 10.

[0059] Specifically, the slider 210 can be vertically slidably disposed in the clamping assembly 100, ensuring that the base 200 can be adjusted in height during installation or as needed. This sliding function enables the base 200 to flexibly adapt to different installation environments and conditions, thereby improving the versatility and flexibility of the monitoring mechanism 300.

[0060] Two ear plates 230 are arranged at intervals along the length direction of the breast wall 10 on one side of the slider 210, facing the gate 20. The ear plates 230 provide mounting support points for the rotating shaft 220, and also provide accurate connections for the installation and positioning of the monitoring mechanism 300. The position and spacing of the ear plates 230 ensure the stable installation of the rotating shaft 220 and provide support for the rotational movement of the monitoring mechanism 300.

[0061] The rotating shaft 220 extends along the length direction of the breast wall 10 and passes through the two ear plates 230. Through the threaded connection with the ear plates 230, the rotating shaft 220 not only maintains stability during use, but also provides a necessary fulcrum for the rotation of the monitoring mechanism 300. The threaded connection of the rotating shaft 220 ensures that it does not accidentally slide or loosen in the ear plates 230, maintaining the structural monitoring stability of the entire monitoring mechanism 300.

[0062] The monitoring mechanism 300 is mounted on the rotating shaft 220 and can rotate around the rotating shaft 220 from a position close to the breast wall 10 to a position away from the breast wall 10. The monitoring mechanism 300 can adjust its working angle so as to perform accurate monitoring operations under different conditions. The adjustable rotation function between the initial position and the debugging position enables the monitoring mechanism 300 to be debugged to the optimal angle for comprehensive monitoring and adjustment of the opening and closing degree of the gate 20 during installation and maintenance, thereby achieving more accurate flood discharge control.

[0063] Please continue reading Figure 4 In an embodiment of the present invention, the slider 210 extends along the length direction of the breast wall 10, and a limiting hole 211 is formed on one side of the slider 210 along its extension direction. One end of the rotating shaft 220 extending out of the ear plate 230 is threadedly connected to the limiting head 600, and the limiting head 600 is detachably connected to the limiting hole 211 through a limiting plate 700.

[0064] Specifically, at least one limiting hole 211 is provided on one side of the slider 210 along its extension direction. The limiting hole 211 is provided to solve the problem of excessive sliding that may occur during the adjustment of the monitoring mechanism 300. Through the limiting hole 211, the monitoring mechanism 300 can be firmly fixed at the debugged preset position to prevent accidental movement, which helps to ensure that the monitoring mechanism 300 is aligned with the target monitoring position on the gate 20 during operation.

[0065] The rotating shaft 220 passes through the ear plate 230 and extends out at one end thereof, and the extended portion is connected to a limit head 600 by means of a thread. The limit head 600 is ensured not to be loosened during operation by means of its threaded connection, and the limit head 600 is detachably connected to the limit hole 211 by means of a limit piece 700, such as by means of a bolt connection, so that the user can quickly and conveniently install or remove the limit piece 700 according to actual operation needs. When debugging and maintaining the system, the disassembly and assembly operation of the limit piece 700 is simple and quick, and the limiting and unlocking functions of the slider 210 can be effectively realized by adjusting the position of the limit piece 700.

[0066] In an embodiment of the present invention, the monitoring mechanism 300 includes a packaging box 310 and a monitoring module 320. The packaging box 310 can rotate around the base 200 between an initial position close to the breast wall 10 and a debugging position away from the breast wall 10. The monitoring module 320 is installed on the packaging box 310. The monitoring module 320 is electrically connected to the control module 400. The monitoring end 321 of the monitoring module 320 is set toward the gate 20. The monitoring module 320 is used to monitor the position of the gate 20 to obtain the opening degree of the gate 20.

[0067] Specifically, when the monitoring module 320 needs to be inspected, repaired or recalibrated, it is only necessary to rotate the packaging box 310 to the debugging position, thereby reducing the complexity of the operation.

[0068] The monitoring module 320 is installed in the packaging box 310, so that the monitoring module 320 is well physically protected, which not only prevents the external environment from affecting its performance, but also prolongs its service life.

[0069] The monitoring end 321 of the monitoring module 320 is set toward the gate 20 to ensure monitoring accuracy. By directly facing the top of the gate 20, the monitoring module 320 can quickly and accurately obtain the position change information of the gate 20, and then accurately calculate its opening degree. Combined with the acquired data, the operator of the hydropower station can make data-driven decisions to improve the safety and efficiency of the dam's flood discharge.

[0070] Please continue reading Figure 1 In an embodiment of the present invention, the gate 20 includes a panel 21 and a beam grid 22 , the beam grid 22 is installed on a side of the panel 21 away from the breast wall 10 , and the monitoring end 321 of the monitoring module 320 is arranged toward the top of the beam grid 22 .

[0071] Specifically, the beam grid 22, as a support and structural reinforcement component of the panel 21, is located on the side of the panel 21 away from the breast wall 10. By aligning the monitoring end 321 with the top of the beam grid 22, the monitoring module 320 can directly obtain important parameters related to the opening degree of the gate 20, that is, as the gate 20 is vertically displaced, the position change of the top of the beam grid 22 can be accurately sensed by the monitoring mechanism 300 because a plurality of open squares facing upward are formed on the top of the beam grid 22. This arrangement improves the monitoring accuracy, especially in situations where the water flow is large, and can overcome the perception deviation caused by water flow or other environmental factors.

[0072] In addition, setting the monitoring end 321 toward the top of the beam grid 22 helps protect the monitoring equipment and reduce the probability of it being directly impacted by the water flow, thereby reducing the damage rate of the equipment.

[0073] In the embodiment of the present invention, the monitoring end 321 of the monitoring module 320 is installed at the bottom of the packaging box 310, and the size of the monitoring end 321 is gradually expanded from the packaging box 310 toward the direction away from the installation box.

[0074] Specifically, the monitoring terminal 321 is installed at the bottom of the packaging box 310, so that it can effectively approach and monitor the change of the opening degree of the gate 20, especially in the flood discharge operation of the hydropower station that requires frequent adjustment, ensuring that the monitoring module 320 can always maintain the best monitoring position, and improving the signal acquisition efficiency between the monitoring terminal 321 and the gate 20. The bottom installation is not only convenient for fixing and protecting the device, but also ensures that the monitoring terminal 321 is not interfered by the outside world, thereby improving the stability and accuracy of monitoring.

[0075] In addition, the gradually expanding size of the monitoring terminal 321 ensures that it has a larger monitoring range and perception capabilities. With the expansion of the size of the monitoring terminal 321, the monitoring module 320 can better cover the dynamic changes when the gate 20 is opened. It can effectively reduce the measurement errors caused by the uneven movement of the gate 20 or changes in environmental factors. Through the expanded monitoring range, the monitoring module 320 can maintain high performance under various flow conditions, thereby achieving more accurate data collection.

[0076] More specifically, the gradually expanding shape of the monitoring end 321 helps reduce signal interference and optimize signal quality. In the case where the monitoring module 320 must handle multiple signal sources or a clutter environment, the gradually expanding shape increases and concentrates the signal power required by the monitoring module 320 during the monitoring process, which helps improve signal quality and increase anti-interference capabilities, thereby achieving a more stable monitoring process.

[0077] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
