[0028] Example 1

[0029] The specific implementation method of this utility model's hydraulic gate opening observation device is described in detail with reference to the accompanying drawings. For example... Figure 1 As shown, this device includes a fixed bracket 1, a sliding measurement assembly 2, and a data acquisition module 3. The fixed bracket 1 consists of a vertical guide rail 4 and a horizontal top beam 5. The vertical guide rail 4 is welded to one side of the gate 17 frame, and the horizontal top beam 5 is bolted to the top of the vertical guide rail 4. The sliding measurement assembly 2 is installed inside the fixed bracket 1 and connected to the gate 17.

The slider 6 is nested inside the vertical guide rail 4 and threadedly connected to one end of the transmission rod 7. A connecting plate 14 is provided on one side of the slider 6. The connecting plate 14 is arc-shaped and bolted to both sides of the gate 17 and the slider 6, respectively.

The data acquisition module 3 is electrically connected to the displacement sensor 8 and is used to receive the displacement signal from the sliding measurement assembly 2.

[0030] Example 2

[0031] Based on Example 1, a ball bearing 9 was added to reduce the friction between the slider 6 and the vertical guide rail 4.

[0032] like Figure 5 As shown, the inner side of the slider 6 is provided with a ball groove, in which multiple balls 9 are embedded. The balls 9 are symmetrically arranged on both sides of the vertical guide rail 4, and are limited by the ball groove. The design of the balls 9 reduces the friction when the slider 6 moves along the vertical guide rail 4. The transmission rod 7 adopts a telescopic structure, including an inner rod and an outer cylinder. The inner rod is hinged to the slider 6, and the outer cylinder is hinged to the movable end of the displacement sensor 8. This telescopic structure can adapt to the length change requirements of the slider 6 at different height positions. The displacement sensor 8 adopts the magnetostrictive principle. Its movable end is threadedly connected to the outer cylinder of the transmission rod 7, and its fixed end is bolted to the horizontal top beam 5.

[0033] Example 3

[0034] Based on Embodiment 1, a guide block 12 is provided to ensure that the slider 12 does not deviate in the horizontal direction.

[0035] The slider 6 has a guide groove on its side, and a guide block 12 is embedded in the guide groove. The guide block 12 is fixed to the inner side of the vertical guide rail 4 by bolts. The guide block 12 cooperates with the guide groove to limit the lateral swing amplitude of the slider 6. The bottom of the horizontal top beam 5 has a reinforcing rib 13. One end of the reinforcing rib 13 is welded to the horizontal top beam 5, and the other end is welded to the top of the vertical guide rail 4 to enhance the overall rigidity of the fixed bracket 1. The slider 6 and the gate 17 are connected by a connecting plate 14. One end of the connecting plate 14 is fixed to the outside of the slider 6 by bolts, and the other end is fixed to the side of the gate 17 by bolts. The connecting plate 14 has an arc-shaped transition section to disperse stress concentration. Figure 2 As shown, the cooperative design of the guide groove of slider 6 and guide block 12 ensures the stable movement of slider 6 in the vertical direction and avoids measurement errors caused by lateral swaying.

[0036] Example 4

[0037] Based on Example 1, a sealing strip 11 is provided to prevent water and foreign objects from entering the interior of the vertical guide rail 4.

[0038] A protective cover 10 is provided on the outer side of the vertical guide rail 4 of the fixed bracket 1. The protective cover 10 is connected to the vertical guide rail 4 by a buckle, such as... Figure 4 As shown, the inner wall of the protective cover 10 is provided with a sealing strip 11, which is tightly fitted to the surface of the vertical guide rail 4 to prevent foreign objects from entering between the slider 6 and the vertical guide rail 4. Figure 3As shown, the snap-on design of the protective cover 10 facilitates disassembly and maintenance, while the sealing strip 11 ensures the cleanliness of the moving environment of the slider 6.

[0039] Example 5

[0040] Based on Embodiment 1, a wireless transmission unit 16 is provided, which can transmit gate displacement information in real time.

[0041] The data acquisition module 3 includes a signal processing unit 15 and a wireless transmission unit 16. The signal processing unit 15 is connected to the displacement sensor 8 via a shielded cable, and the wireless transmission unit 16 is fixed to the top surface of the horizontal beam 5 with screws. The signal processing unit 15 converts the analog signal from the displacement sensor 8 into a digital signal and transmits it to the remote monitoring terminal via the wireless transmission unit 16.

[0042] During actual operation, when the gate 17 rises or falls, the slider 6 moves synchronously with the gate 17. The balls 9 inside the slider 6 roll along the surface of the vertical guide rail 4, reducing friction and ensuring smooth movement of the slider 6. The movement of the slider 6 causes the transmission rod 7 to shift. The telescopic structure of the transmission rod 7 automatically adjusts its length according to the height of the slider 6, ensuring that the transmission rod 7 remains connected to the displacement sensor 8. The displacement sensor 8 detects the displacement of the transmission rod 7 using the magnetostrictive principle and transmits the displacement signal to the signal processing unit 15. The signal processing unit 15 converts the analog signal output by the displacement sensor 8 into a digital signal and then sends the data to the remote monitoring terminal via the wireless transmission unit 16. The remote monitoring terminal displays the opening information of the gate 17 in real time, thus achieving accurate monitoring of the gate 17's opening. The wireless transmission unit 16 of the data acquisition module 3 uses the low-power Bluetooth protocol, with a signal transmission distance of no less than 50 meters, meeting the long-distance data transmission requirements of water conservancy projects. The low-power design of the wireless transmission unit 16 extends the device's battery life, while the use of the Bluetooth protocol simplifies the connection process with the remote monitoring terminal. The reinforcing ribs 13 of the fixed bracket 1 enhance the overall rigidity and prevent structural deformation caused by external loads or vibrations. The protective cover 10 and the sealing strip 11 effectively prevent water from entering between the slider 6 and the vertical guide rail 4, extending the service life of the device.

[0043] In water conservancy projects, this device can be applied to various types of gate systems, such as reservoir spillway gates and irrigation canal control gates. By installing this device, operators can monitor the gate opening information in real time via a remote monitoring terminal, thereby optimizing gate operation strategies. For example, during reservoir spillway operations, operators can adjust the gate opening degree based on real-time opening data to control the discharge flow and prevent downstream areas from being threatened by floods. In irrigation canals, this device helps operators precisely control water flow, improving water resource utilization efficiency. By integrating this device into the automated control system of water conservancy projects, intelligent gate management can be achieved, further enhancing the safety and efficiency of project operation.

[0044] All components in this embodiment are made of corrosion-resistant materials to withstand the humid environment of hydraulic engineering sites. For example, the vertical guide rail 4 and the horizontal top beam 5 are made of stainless steel, the slider 6 and the transmission rod 7 are made of high-strength aluminum alloy, and the housings of the displacement sensor 8 and the data acquisition module 3 are designed to be waterproof and dustproof. These material and design choices ensure the long-term stable operation of the device in harsh environments.

[0045] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure.
