[0017] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0019] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0020] The following is combined with Figures 1 to 4 The embodiments shown illustrate the technical solution of this utility model: This utility model embodiment provides a water level monitoring device for hydraulic construction, such as... Figures 1-4 As shown, the enclosure includes a waterproof barrier 1, a gate assembly 2, a water storage tank 3, a guide rod 4, a floating plate 5, and an observation ruler 6. The waterproof barrier 1 has a through-hole 101. The gate assembly 2 is located on the waterproof barrier 1 and above the water outlet 101. The water storage tank 3 is located on the outside of the waterproof barrier 1 and is connected to the water outlet 101. The guide rod 4 is erected inside the water storage tank 3. The floating plate 5 is located inside the water storage tank 3 and is slidably connected to the guide rod 4. The observation ruler 6 is erected on top of the floating plate 5.

[0021] Specifically, the waterproof enclosure 1 provides a stable installation foundation for the entire device; the water outlet 101 allows water to flow smoothly into the water storage tank 3, ensuring that the water level in the water storage tank 3 is synchronized with the external water level and guaranteeing the accuracy of monitoring; the sliding cooperation between the guide rod 4 and the floating plate 5 restricts the movement trajectory of the floating plate 5 and prevents it from tilting or deviating; the observation ruler 6 is erected on the top of the floating plate 5 to realize intuitive and visual observation of the water level height without complicated operation.

[0022] During implementation, a waterproof enclosure 1 is installed at the designated monitoring location in the water conservancy construction area. A water outlet 101 is drilled through the waterproof enclosure 1, and the gate assembly 2 is assembled on the waterproof enclosure 1 and positioned above the water outlet 101. A water storage tank 3 is set outside the waterproof enclosure 1, ensuring that the water storage tank 3 is connected to the water outlet 101. A guide rod 4 is vertically fixed inside the water storage tank 3, and a floating plate 5 is slidably connected to the guide rod 4 through a pre-set through hole, ensuring that the floating plate 5 can rise and fall freely along the guide rod 4. Finally, an observation ruler 6 is vertically fixed on the top of the floating plate 5, with the scale of the observation ruler 6 facing a direction that is convenient for staff to observe. The water level can be directly read by observing the scale of the water storage tank 3 through the scale of the observation ruler 6.

[0023] In an exemplary embodiment, see Figure 2 The water storage tank 3 is also provided with a drain outlet 301 on the side opposite to the water outlet 101, and a sealing door 302 is provided at the drain outlet 301.

[0024] Specifically, the drain outlet 301 provides a cleaning channel for the water storage tank 3, allowing for the periodic removal of deposited silt and debris, preventing impurities from affecting the sliding stability of the floating plate 5. The sealing door 302 remains closed when not being cleaned, ensuring the water storage tank 3's airtightness and preventing water leakage that could lead to inaccurate water level monitoring. This structure, in conjunction with the water storage tank 3 and the floating plate 5, ensures continuous monitoring accuracy, improves the ease of maintenance, and extends the device's service life.

[0025] During implementation, the size of the drain outlet 301 is adapted to the needs of impurity cleaning and water replacement; a sealing door 302 is installed at the drain outlet 301. When it is necessary to clean the water storage tank 3 or replace the internal water, the sealing door 302 is opened and impurities and old water are discharged through the drain outlet 301. After cleaning is completed, the sealing door 302 is closed to restore the sealing state of the water storage tank 3 and ensure that the water level monitoring is carried out normally.

[0026] In an exemplary embodiment, reference is made to... Figure 3 and Figure 4 The water level detection device also includes an alarm component 7, which comprises a mounting box 701, an alarm 702, a trigger switch 703, a trigger spring 704, a trigger plate 705, a traction rope 706, and a counterweight ball 707. The mounting box 701 is located on the top of the water storage tank 3, and a clearance hole 7011 is provided on the side of the mounting box 701 closest to the water storage tank 3. The alarm 702 is located on the side of the mounting box 701 away from the clearance hole 7011. The trigger switch... 703 is located inside the mounting box 701 and is electrically connected to the alarm 702; the trigger spring 704 is located on the inner wall of the mounting box 701 on the side with the clearance hole 7011; the trigger plate 705 is connected to the end of the trigger spring 704 away from the clearance hole 7011; one end of the traction rope 706 is connected to the trigger plate 705, and the other end passes through the clearance hole 7011 and hangs freely in the water storage tank 3; the counterweight ball 707 is located at the end of the traction rope 706 that hangs freely.

[0027] Specifically, the mounting box 701 provides protection for internal components, preventing moisture and impurities in the hydraulic construction environment from damaging electrical components. The trigger spring 704, trigger plate 705, traction rope 706, and counterweight ball 707 work together to move the floating plate 5 upwards by adjusting the water level, thereby moving the counterweight ball 707. This releases the tension on the trigger plate 705 via the traction rope 706, causing the trigger plate 705 to contact the trigger switch 703, achieving a mechanical trigger for early warning. This eliminates the need for complex control logic and ensures reliable response. The trigger switch 703 is electrically connected to the alarm 702, ensuring a rapid alarm signal is issued when the water level is abnormal. The coordinated operation of these components enables automatic early warning of abnormal water levels, improving the safety of hydraulic construction.

[0028] In implementation, a clearance hole 7011 is made on the side of the mounting box 701 closest to the water storage tank 3; the alarm 702 is fixed on the side of the mounting box 701 away from the clearance hole 7011; the trigger switch 703 is installed inside the mounting box 701 and electrically connected to the alarm 702 via a wire; one end of the trigger spring 704 is fixed to the inner wall of the mounting box 701 on the side with the clearance hole 7011; and the trigger plate 705 is fixedly connected to the trigger spring 704 away from the clearance hole 7011. One end of the traction rope 706 is fixedly connected to the trigger plate 705, and the other end passes through the clearance hole 7011 and hangs freely in the water storage tank 3. The counterweight ball 707 is fixed to the free-hanging end of the traction rope 706. When the water level rises, it causes the floating plate 5 to float up. Under the buoyancy of the floating plate 5, the counterweight ball 707 floats up, the traction rope 706 loosens, the trigger spring 704 pushes the trigger plate 705 to touch the trigger switch 703, and the alarm 702 is activated to send an alarm signal.

[0029] In an exemplary embodiment, see Figure 2 The waterproof enclosure 1 is located above the water outlet 101 and has a through groove 102. The gate assembly 2 includes a mounting frame 201, a winding roller 202, a lifting rope 203, and a sealing gate 204. The mounting frame 201 is erected on the top of the waterproof enclosure 1. The winding roller 202 is rotatably connected to the mounting frame 201. One end of the lifting rope 203 is wound on the winding roller 202, and the other end hangs freely. The sealing gate 204 is slidably connected in the groove 102, and its top is connected to the free end of the lifting rope 203.

[0030] Specifically, the chute 102 provides precise guidance for the sealing door 204, ensuring smooth up-and-down sliding and preventing deviation or jamming; the mounting bracket 201 provides stable support for the winding roller 202, which controls the lifting and lowering of the sealing door 204 via the winding and releasing of the lifting rope 203, making operation convenient; the sealing door 204 allows flexible control of the opening and closing of the water outlet 101, allowing water to flow into the water storage tank 3 during monitoring and closing it during maintenance to prevent water flow interference. This structure, in conjunction with the waterproof enclosure 1 and the water outlet 101, achieves controllable water flow introduction, improves the flexibility and practicality of the device, and solves the problems of cumbersome installation and inflexible adjustment in traditional devices.

[0031] In an exemplary embodiment, see Figure 3 There are two guide rods 4, which are symmetrically erected in the water storage tank 3.

[0032] Specifically, compared to a single guide rod 4, the two symmetrically positioned guide rods 4 more comprehensively restrict the degrees of freedom of movement of the float plate 5, preventing it from tilting, twisting, or shifting horizontally when the water level changes. This ensures that the float plate 5 remains horizontal, thereby allowing the observation ruler 6 to rise and fall vertically and improving the accuracy of water level readings. The symmetrical arrangement of the two guide rods 4 ensures that the float plate 5 is subjected to uniform force, reducing wear during sliding and extending the service life of components. Together with the float plate 5 and the observation ruler 6, this further optimizes the accuracy of intuitive monitoring and solves the problem of inaccurate results from existing measuring equipment.

[0033] In an exemplary embodiment, see Figure 2 The top of the guide rod 4 is equipped with a barrier plate 401.

[0034] Specifically, a baffle plate 401 is added to the top of the guide rod 4, which effectively prevents the floating plate 5 from detaching from the guide rod 4 due to abnormally high water levels. This ensures that the floating plate 5 always maintains a sliding fit with the guide rod 4, avoiding monitoring interruption or device damage. The baffle plate 401, together with the two symmetrical guide rods 4 and the floating plate 5, further improves the operational reliability of the device, especially suitable for sudden high water level scenarios that may occur during water conservancy construction. It fills the protection gap of the device under extreme water levels and ensures the continuity of monitoring functions.

[0035] In an exemplary embodiment, see Figure 3 The alarm component 7 also includes a warning light 708, which is located on the top of the water tank 3 and electrically connected to the trigger switch 703.

[0036] Specifically, the warning light 708 and the alarm 702 form a dual sound and light warning mechanism. Compared to a single sound warning, this provides a wider coverage and a more noticeable effect. In noisy environments during water conservancy construction, in long-distance monitoring scenarios, or during nighttime operations, the light signal of the warning light 708 can be quickly detected by workers, preventing warnings from being missed due to limited sound propagation. The warning light 708, in conjunction with the trigger switch 703 and the alarm 702, enhances the practicality of the warning function and further improves the safety protection level of water conservancy construction.

[0037] For example, the lifting rope 203 is a steel cable.

[0038] Specifically, the lifting rope 203 is designed as a steel cable. Utilizing the high strength, high wear resistance, and strong corrosion resistance of steel cables, it is suitable for the harsh environments of hydraulic construction, characterized by dampness, high friction, and susceptibility to rust. This avoids the problems of breakage, wear, and corrosion that occur with traditional ropes over long-term use, ensuring the reliability and service life of the gate assembly 2. The steel cable, in conjunction with the winding roller 202 and the sealing gate 204, can stably transmit winding force, preventing rope slack or breakage during lifting that could lead to loss of control of the sealing gate 204. This reduces the frequency of device maintenance and improves overall operational stability.

[0039] The principle involved in this utility model is as follows: A waterproof enclosure 1 is used to block the water area at the construction site, ensuring a gentle water flow. Then, by lifting the sealing gate 204, the water enclosed by the waterproof enclosure 1 flows into the water storage tank 3 through the outlet 101. The height of the water storage tank 3 is the same as the height of the waterproof enclosure 1. Based on the principle of communicating vessels, it is known that the water level in the water storage tank 3 and the water level in the waterproof enclosure 1 remain consistent. Therefore, by introducing water into the water storage tank 3, the buoyancy of the water flow lifts the floating plate 5, and the observation ruler 6 rises synchronously with the floating plate 5. Workers only need to read the value on the observation ruler 6 to directly determine the water level. The length of the traction rope 706 is set so that when the water level reaches the warning height, the trigger switch 7 is activated. 03. When the water level rises, the float plate 5 rises, and the float plate 5 will lift the counterweight ball 707 under its own buoyancy, thereby releasing the tension of the traction rope 706 on the trigger plate 705, thus offsetting the pressure of the trigger plate 705 on the spring. As the water level continues to rise, the tension of the traction rope 706 on the trigger plate 705 becomes less and less, and the trigger spring 704 will continue to push the trigger plate 705 towards the trigger switch 703 until the trigger switch 703 is triggered. The trigger switch 703 will turn on the alarm 702 and the warning light 708 to remind the staff. When too much impurity accumulates in the water storage tank 3, the sealing door 204 will be closed and the sealing door 302 will be opened to discharge and clean the impurities in the water storage tank 3.

[0040] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
