[0037] Example 1

[0038] Reference Figure 1 - Figure 5 The first embodiment of the present invention provides a dam water level monitoring device. This device includes a movable component 100, which includes a receiving component 101, left and right components 102, and upper and lower components 103. The left and right components 102 are disposed on the receiving component 101, and the upper and lower components 103 are disposed on the receiving component 101. Through the interaction between the receiving component 101, the left and right components 102, and the upper and lower components 103, the water level monitoring device can be adjusted to any position.

[0039] Specifically, the receiving component 101 includes a reservoir gate 101a, a spillway gate 101b, a trash rack 101c, and a mounting frame 101d. The spillway gate 101b, the trash rack 101c, and the mounting frame 101d are mounted on the reservoir gate 101a, which is located on the dam. The spillway gate 101b is movably connected to the reservoir gate 101a, the trash rack 101c is fixedly connected to the reservoir gate 101a, and the mounting frame 101d is fixedly connected to the reservoir gate 101a. The mounting frame 101d is positioned opposite the floodgate 101b and the trash rack 101c. The mounting frame 101d is positioned in the middle of the trash rack 101c. This facilitates the installation of water level monitoring equipment on both sides of the trash rack 101c. The mounting frame 101d has some internal space, which is convenient for designing other structures on it. The connection relationship between the reservoir gate 101a, the floodgate 101b, the trash rack 101c and the mounting frame 101d can be used to construct the initial position for installing the water level monitoring equipment.

[0040] Furthermore, the left and right components 102 include a transverse sliding groove 102a, a transverse sliding column 102b, a moving block 102c, a connecting block 102d, and a mounting block 102e. The transverse sliding groove 102a is disposed on the mounting frame 101d and is formed on the inner side wall of the mounting frame 101d. A transverse sliding groove 102a is provided on both sides of the mounting frame 101d. The transverse sliding column 102b is disposed on the transverse sliding groove 102a and is movably connected to the transverse sliding groove 102a. The transverse sliding column 102b is mounted on two transverse sliding grooves. On slot 102a, a horizontal sliding column 102b is provided on both sides of mounting frame 101d. Each horizontal sliding column 102b is composed of two rectangular columns with a certain distance between them. The rectangular columns on the horizontal sliding column 102b have "L"-shaped slots on their opposite sides to facilitate the movement of objects. A moving block 102c is set on the horizontal sliding column 102b and is movably connected to the horizontal sliding column 102b. There are several moving blocks 102c, and each rectangular column on the horizontal sliding column 102b has a moving block 102c. One, the width of the moving block 102c is equal to one-third of the length of the horizontal moving column 102b, so that the moving block 102c has a certain moving distance on the horizontal moving column 102b. The connecting block 102d is set on the moving block 102c and is fixedly connected to the moving block 102c. The width of the connecting block 102d is the same as that of the moving block 102c. The connecting block 102d is used to connect the moving blocks 102c on the horizontal moving column 102b together, and the connecting block 102d is located between the horizontal moving columns 102b. To facilitate simultaneous control of movement, mounting block 102e is set on connecting block 102d. Mounting block 102e is fixedly connected to connecting block 102d, and its length exceeds the width of transverse column 102b. Mounting block 102e is used to provide an installation position for water level monitoring equipment. In this way, mounting block 102e can move back and forth at the position of transverse column 102b and move left and right on transverse groove 102a under the action of transverse column 102b and transverse groove 102a, avoiding measurement dead zones caused by installation position limitations.

[0041] Furthermore, the upper and lower components 103 include rising grooves 103a, limiting posts 103b, limiting grooves 103c, and positioning grooves 103d. The rising grooves 103a and limiting posts 103b are disposed on the mounting frame 101d. The rising grooves 103a are formed on the mounting frame 101d, and there are several rising grooves 103a. Each rising groove 103a corresponds to and is connected to the transverse moving post 102b. Each side of the transverse moving post 102a has several rising grooves 103a, facilitating the vertical movement of the transverse moving post 102b. The limiting post 103b is fixedly connected to the mounting frame 101d and is located in the middle of the transverse moving post 102b, with its width occupying one-third of the length of the transverse moving post 102b. This allows the moving block 102c to carry the mounting block 103d. The 2e moves on the transverse column 102b, allowing the mounting block 102e to move from one side of the mounting frame 101d to the other side. The limiting column 103b also allows the transverse column 102b to contact and move on its lower side. The limiting groove 103c is provided on the limiting column 103b. The limiting groove 103c is opened on the limiting column 103b and corresponds to the transverse column 102b and also corresponds to the rising groove 103a. The setting of the limiting groove 103c allows the transverse column 102b to move upward and embed into the limiting column 103b when it moves to the appropriate position, and also realizes the function of floating up and down. The positioning groove 103d is provided on the rising groove 103a. The positioning groove 103d is opened on the rising groove 103a and is a rectangular groove with a certain depth opened in the rising groove 103a.

[0042] During operation, by setting an installation frame 101d on the reservoir gate 101a and positioning the installation frame 101d at the corresponding position of the trash rack 101c, the installation blocks 102e on both sides of the installation frame 101d can be moved to both sides of the trash rack 101c. Furthermore, by moving the installation blocks 102e, under the combined action of the moving block 102c on the transverse block and the connecting block 102d on the installation block 102e, the installation blocks 102e can move back and forth corresponding to the position of the trash rack 101c. The adjustment, and the movement of the transverse column 102b on the transverse groove 102a, allow the mounting block 102e to move left and right along with the mounting frame 101d. Finally, under the action of the upper and lower grooves and the limiting groove 103c on the limiting column 103b, the entire mounting block 102e moves upward with the transverse column 102b, making the installation of the water level monitoring equipment flexible and allowing it to be moved to a suitable monitoring position as needed, facilitating the subsequent installation of the monitoring equipment.

[0043] Example 2

[0044] Reference Figure 1 - Figure 9This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the device includes a mounting assembly 200, including a pushing member 201, a rotating member 202, and an assembly 203. The pushing member 201 is disposed on the left and right members 102, the rotating member 202 is disposed on the pushing member 201, and the assembly 203 is disposed on the pushing member 201. Through the interaction between the pushing member 201, the rotating member 202, and the assembly 203, and through their action on the moving assembly 100, the entire device can be adjusted and fixed according to the position to be monitored.

[0045] Specifically, the pushing component 201 includes an auxiliary groove 201a, a rotating block 201b, a pushing groove 201c, a follower block 201d, a pushing plate 201e, a positioning plate 201f, and an auxiliary block 201g. The auxiliary groove 201a is disposed on the mounting block 102e and is composed of stepped grooves on both sides and a circular groove connecting the stepped grooves on both sides. It provides a moving space for subsequent equipment movement. The rotating block 201b is disposed on the auxiliary groove 201a and is rotatably connected to the mounting block 102e. The rotating block 201b is cylindrical. The pushing groove 201c and the follower block 201d are disposed on the rotating block 201b. A semi-circular structure is located on one side of the rotating block 201b, creating a groove with a certain amount of movement space in the middle of one side of the rotating block 201b. The follower block 201d is fixedly connected to the rotating block 201b. The follower block 201d is a trapezoidal structure with a certain curvature on one side. The curved side facilitates pushing other contacting objects to move when the rotating block 201b rotates and drives the follower block 201d to move synchronously. The push plate 201e is set on the push groove 201c and is movably connected to the push groove 201c. The push plate 201e has a certain curvature and is close to the center of the rotating block 201b, so that it can be adapted to push the push block to move. The push plate 201e moves in the push groove 201c.

[0046] The positioning plate 201f is mounted on the push plate 201e and is fixedly connected to the push plate 201e. A positioning plate 201f is located on both sides of the push plate 201e. Each positioning plate 201f has an "F" structure, with each "I" section having a different length, allowing for a certain amount of movement. Its movement length is adapted to the auxiliary groove 201a to allow the rotating block 201b to rotate, driving the push plate 201e to move towards the transverse groove 102a. Its "|" section is connected to the push plate 201e. As the push plate 201e moves... The longest part of the positioning plate 201f can be moved into the positioning groove 103d to achieve the function of embedding and fixing, which facilitates the fixing function after the installation block 102e moves up. The auxiliary block 201g is set on the push plate 201e. The auxiliary block 201g is fixedly connected to the push plate 201e and is set in the auxiliary groove 201a. It moves in the auxiliary groove 201a and can restrict the movement of the push plate 201e. The auxiliary block 201g has a "7" structure to meet the movement structure in the auxiliary groove 201a.

[0047] Furthermore, the rotating component 202 includes an entry groove 202a, a first spring 202b, an entry post 202c, an adapter block 202d, and a rotating groove 202e. The entry groove 202a is disposed on the auxiliary block 201g, and the entry groove 202a is formed on the auxiliary block 201g such that a groove of a certain length is formed on one side of the auxiliary block 201g, and it is close to the rotating block 201b. The first spring 202b is disposed on the entry groove 202a, and the first spring 202b is fixed. The entry post 202c is fixedly connected to the entry slot 202a and mounted on the first spring 202b. The entry post 202c can move within the entry post 202c along with the first spring 202b. The entry post 202c has a structure with a straight surface on one side and an arc surface on the other. The straight surface is away from the push slot 201c, and the arc surface is close to the push slot 201c. Thus, when the entry post 202c... c can be biased to push the groove 201c to move. When moving in the opposite direction, it will retract into the groove 202a under the action of the first spring 202b due to the nature of the entering post 202c itself. The adapter block 202d is set on the entering post 202c. The adapter block 202d is movably connected to the entering post 202c. A groove is opened on one side of the adapter block 202d to facilitate the entry of the entering post 202c. The top of the adapter block 202d has a small convex ring that can be embedded into the follower block 201d. The groove inside allows for a knocking sound and force to be generated when the insertion post 202c is squeezed and then released after the fitting is complete, indicating that the insertion post 202c has been installed with the fitting block 202d. The rotating groove 202e is set on the fitting block 202d to facilitate the rotation of the rotating block 201b. When the rotating block 201b moves in the opposite direction, the insertion post 202c will retract into the insertion groove 202a.

[0048] Furthermore, assembly 203 includes a first nut block 203a, a pressure level gauge 203b, an auxiliary pipe 203c, a second nut block 203d, a connecting block 203e, and a radar level gauge 203f. The first nut block 203a is mounted on the follower block 201d and is fixedly connected to it. The first nut block 203a has threads to facilitate threaded connections with other objects. The pressure level gauge 203b is mounted on the first nut block 203a and can be rotatably connected via the threads on the first nut block 203a. It is located between the adapter blocks 202d for easy disassembly and replacement. The auxiliary pipe 203c is mounted on the adapter block 202d and is connected to it. The auxiliary pipe 203c extends into the water to facilitate the extension of the pressure level gauge 203b into the water. The system monitors water levels. A second nut block 203d is mounted on mounting block 102e. There are two second nut blocks 203d, one on each side of the first nut block 203a. The second nut block 203d has threads that allow for connection. A connecting block 203e is mounted on the second nut block 203d and connected to it via threads. One part of the connecting block 203e is threaded, and the other part is a cylindrical tube to protect the object inside. A radar level gauge 203f is mounted on the connecting block 203e and connected to it. The cylindrical part of the connecting block 203e protects the radar level gauge 203f. The radar level gauge 203f does not need to extend into the water; it can monitor water level changes while remaining on the surface.

[0049] Since the entire mounting frame 101d has two mounting blocks 102e, one mounting block 102e is equipped with two radar level gauges 203f and one pressure level gauge 203b, and the other mounting block 102e is equipped with one radar level gauge 203f and two pressure level gauges 203b, each mounting block 102e has a first threaded block and two second threaded blocks on both sides of the first threaded block for adaptation. A single level gauge is connected and installed on the first threaded block in the middle position.

[0050] The remaining structure is the same as that in Example 1.

[0051] Operation process: By installing a pressure-type water level gauge 203b onto the first nut block 203a, its rotation direction is opposite to the direction in which the rotating block 201b drives the follower block 201d to move, thus enabling a threaded connection. Then, by rotating the rotating block 201b and the follower block 201d in the same direction, the push plate 201e on the rotating block 201b drives the positioning plate 201f to move, causing the positioning plate 201f to enter the positioning groove 103d for fixation. Simultaneously, this will cause the auxiliary... When the entry post 202c on block 201g enters with the assistance of the first spring 202b and connects with the adapter block 202d and the first nut block 203a, it will generate a certain release force after compression and knocking sound during entry, which is used as a reminder. Then, the pressure level gauge 203b or radar level gauge 203f is installed on the adapter block 202d. Other pressure level gauges or radar level gauges 203f are installed on the mounting block 102e through the second nut block 203d, so that they can be used for subsequent monitoring operations.

[0052] Example 3

[0053] A third embodiment of the present invention provides an automatic control method for dam gates, comprising the following steps:

[0054] S1. Water level gauge installation stage: Two radar water level gauges 203f (radar 1 and radar 2) and one pressure water level gauge 203b (pressure type 1) are installed at key monitoring points in front of the trash rack 101c of the hydropower station dam. Two pressure water level gauges 203b (pressure type 2 and pressure type 3) and one radar water level gauge 203f (radar 3) are installed behind the trash rack 101c. The selection of these water level gauges is based on their measurement accuracy and adaptability to environmental factors to ensure stable operation under subtropical mountain climate conditions. The installation position of the water level gauges can be adjusted and fixed at will according to the device design to avoid measurement dead zones caused by installation position restrictions. The water level gauges collect dam water level signals.

[0055] S2. Data Transmission and Processing Stage: The collected water level signals are processed and analyzed to obtain the calculated water level value. All water level gauges are connected to the dam's local control unit via cables. The local control unit uses a three-average strategy to process the received water level data: when all water level gauges are working normally, the average value of two radar water level gauges (203f) is used as the control basis; if any radar water level gauge (203f) fails, the data from the other radar water level gauge (203f) is used; if both radar water level gauges (203f) fail, the data from the submersible water level gauge is used. Furthermore, the local control unit is equipped with a filtering algorithm to eliminate noise interference, a threshold value setting to identify water level gauge failures, and fault-tolerant filtering parameters to ensure the system can still operate normally when some equipment fails.

[0056] S3, Water Level Monitoring, Alarm, and Automatic Control Stage: Based on the calculated water level value, the gates are automatically opened and closed. The local control unit analyzes water level trends using real-time and historical data, and determines whether a flood warning needs to be issued based on a preset target water level dead zone (e.g., 1542.15m as the upper limit control water level). When the water level reaches or exceeds this limit, the local control unit automatically sends a signal to the alarm system in the downstream flood discharge area and issues a warning to operators via the SCADA system.

[0057] Under normal communication conditions, operators can manually switch between single control and joint control modes. When joint control mode is selected, the local control unit will automatically perform gate opening and closing operations according to the water level. For example, when the upstream water level is continuously higher than the control water level (default 1542m) and a continuous net inflow is detected, the local control unit will open the sand flushing gate and the flood discharge gate in sequence. The initial opening height of the sand flushing gate is 0.1m, and thereafter the opening height will not exceed 1m each time according to the water level change. If the upstream water level drops to the lower limit control water level or below (e.g., default 1541.85m), the local control unit will close the flood discharge gate 101b in sequence.

[0058] S4. Emergency and Optimization Processing Phase: During gate control, if the opening and closing relay nodes stick together or external electromagnetic interference causes malfunction, the anti-malfunction protection program in the local control unit will monitor in real time and issue a stop command in a timely manner; if the rate of change of the gate opening feedback value is detected to exceed the preset range, an alarm will be automatically activated; in addition, the gate stop control logic has been optimized, and logic has been added to automatically stop the gate if the feedback opening value is greater than or less than the given value during the gate lifting or closing process, so as to prevent the gate from repeatedly rising and falling.

[0059] S5. Simulation Mode Testing Phase: To train operators or conduct system testing, the local control unit has a simulation mode. In this mode, the actual physical gate will not move, but the results of gate operation and the impact of water level changes on the system can be simulated and displayed on the host computer screen in the central control center. This allows operators to familiarize themselves with the operating system or test new parameters without affecting actual production.
