Description

Technical Field

[0001] This utility model belongs to the field of measuring device technology, and in particular relates to an auxiliary device for precise control of water level in a sluice gate that is easy to adjust. Background Technology

[0002] When a pumping station draws water, it only takes clean water from the upper part, so there are requirements for the water level. This is where adjustable control gates are needed. In water conservancy projects, agricultural irrigation, urban water supply and other fields, control gates are an important water level control device and are widely used for water level regulation in rivers, canals, reservoirs and other water bodies.

[0003] In actual reservoir water level monitoring, the water surface is often subject to significant wave fluctuations due to factors such as wind, flood discharge, and inflow / outflow. These surface fluctuations cause traditional buoy-type water level gauges to float considerably, affecting measurement accuracy and causing considerable inconvenience for on-site personnel. This fluctuation is particularly pronounced during flood season or under extreme weather conditions.

[0004] To address these issues, we provide an easily adjustable auxiliary device for precise control of the water level in a sluice gate. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an auxiliary device for precise control of water level in a sluice gate that is easy to adjust, including a vertically fixed vertical rod, and a measuring device that can slide along the vertical direction is provided on the outer wall of the vertical rod; the measuring device includes an outer cylinder that passes through the water level line and is placed vertically; the outer wall of the outer cylinder is an arc-shaped surface that points from the upper and lower sides to its center and is concave inward; a sliding shaft is coaxially provided in the inner cavity of the outer cylinder, the top end of the sliding shaft extends out of the surface of the outer cylinder, and scale lines are provided on its peripheral side; a float ring is slidably provided on the peripheral side of the sliding shaft along its axial direction, and a number of float balls are evenly distributed in a circular array near the center of the peripheral side of the outer cylinder.

[0006] The present invention is further configured such that when waves occur, the float causes the outer cylinder to change position accordingly, and the arc-shaped surface of the outer wall of the outer cylinder directly contacts the undulating water surface, thus intercepting and returning the water waves that are impacting the inner cavity of the outer cylinder.

[0007] The present invention is further configured such that the water level in the inner cavity of the outer cylinder changes in the vertical direction but remains within the inner cavity of the outer cylinder.

[0008] The present invention is further configured such that the arc-shaped surface of the outer wall of the outer cylinder corresponds to a part of a complete arc surface, and the angle corresponding to the arc-shaped surface is between 60° and 150°.

[0009] The present invention is further configured such that the measuring device includes an index ring that is vertically slidably disposed on the circumferential side of the slide shaft, the index ring being located above the float ring, and a connecting shaft being fixed between the index ring and the float ring.

[0010] The present invention is further configured such that a mounting bracket is fixed on the vertical rod, and a slip ring is vertically slidably disposed on the periphery of the vertical rod, and the slip ring is fixedly connected to the measuring device.

[0011] The present invention has the following beneficial effects: 1. The present invention transforms the macroscopic into the microscopic. When waves occur, from a macroscopic perspective, the water level will change significantly. From a microscopic perspective, the water is divided into countless small parts, and the water level in each small part changes slightly. The inner cavity of the outer cylinder is selected as one of these parts. The water level in the inner cavity of the outer cylinder can be regarded as unaffected by the waves and will not change significantly. Therefore, the water level can still be measured relatively stably when waves occur.

[0012] 2. When waves occur, the waves will impact the arc-shaped surface of the outer wall of the outer cylinder. The arc-shaped surface forms a protective barrier for the inner cavity of the outer cylinder, reducing the swing amplitude of the water, float ring and other components in the inner cavity of the outer cylinder. The water waves that are impacting the inner cavity of the outer cylinder are guided back by the arc-shaped surface, thereby improving the stability of the measuring device.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation

[0022] Please see Figure 1-3 This utility model is an auxiliary device for precise control of water level in a control gate that is easy to adjust, including a vertically fixed vertical rod 1, and a measuring device that can slide along the vertical direction is provided on the outer wall of the vertical rod 1.

[0023] A mounting bracket 9 is fixed on the vertical rod 1, and a slip ring 10 is vertically and slidably arranged on the side of the vertical rod 1. The slip ring 10 is fixedly connected to the measuring device.

[0024] Specifically, before using the device, the mounting frame 9 can be fixed to the dam wall near the water level with fastening bolts, so that the measuring device can float near the water level line. When the water level rises or falls, the measuring device will move vertically through the slip ring 10 to prevent the measuring device from tipping over. The vertical rod 1 is marked with relatively large intervals. By observing the position of the slip ring 10, the approximate range of the water level can be known.

[0025] Specifically, the measuring device includes an outer cylinder 2 that runs through the water level line and is placed vertically; the water level inside the outer cylinder 2 changes in the vertical direction but remains inside the outer cylinder 2.

[0026] Specifically, when waves occur, from a macroscopic perspective, the water level will change significantly. From a microscopic perspective, if the water is divided into countless small parts, the water level in each small part will change slightly. The inner cavity of the outer cylinder 2 is selected as one of these parts as the microscopic location for measuring the water level. The water level in the inner cavity of the outer cylinder 2 can be considered to be unaffected by the waves and will not change significantly. Therefore, the water level can still be measured relatively stably when waves occur.

[0027] Furthermore, several floats 6 are evenly distributed in a circular array on the two sides of the outer cylinder near its center;

[0028] Specifically, the float 6 floats near the water level line, thereby keeping the outer cylinder 2 near the water level line and preventing the outer cylinder 2 from entering the water and making it impossible to measure the water level.

[0029] Furthermore, a sliding shaft 3 is coaxially arranged in the inner cavity of the outer cylinder 2; the top end of the sliding shaft 3 extends out of the surface of the outer cylinder 2, and scale lines 4 are provided on its peripheral side; a float ring 5 is slidably arranged on the peripheral side of the sliding shaft 3 along its axial direction.

[0030] The measuring device also includes an index ring 7 that is vertically slidably disposed on the side of the slide shaft 3. The index ring 7 is located above the float ring 5, and a connecting shaft 8 is fixed between the index ring 7 and the float ring 5.

[0031] Specifically, the float 5 floats relatively stably near the water level line. When the water level changes, the float 5 moves up and down, which in turn moves the connecting shaft 8, which in turn moves the indicator ring 7. The scale line 4 is located above the outer cylinder 2 on the sliding shaft 3. The approximate range of the water level can be understood through the sliding ring 10. The position of the indicator ring 7 on the scale line 4 is the precise value of the water level, thus improving the accuracy of the reading.

[0032] Furthermore, the outer wall of the outer cylinder 2 is an arc-shaped surface that points from the upper and lower sides toward its center and is concave inward;

[0033] The arc-shaped surface of the outer wall of the outer cylinder 2 corresponds to a part of a complete arc surface, and the angle between the arc-shaped surface and the arc surface is between 60° and 150°.

[0034] Specifically, when wave floating occurs, the waves will impact the arc-shaped surface of the outer wall of the outer cylinder 2. The arc-shaped surface forms a protective barrier for the inner cavity of the outer cylinder 2, reducing the swing amplitude of the water, float ring 5 and other components in the inner cavity of the outer cylinder 2. The water waves impacting the inner cavity of the outer cylinder 2 are guided back by the arc-shaped surface, thereby improving the stability of the measuring device.
