Technical Field

[0002] With the development of science and technology and the increasing demand for water resource management, smart hydrology construction has become an important means to promote the sustainable use and management of water resources. Smart hydrology construction refers to the application of information technology to various sensors, networks and intelligent algorithms in hydrological monitoring, water conservancy management and water resource scheduling. Smart hydrology construction is of great significance to the sustainable development of modern society. It can improve water resource management capabilities, prevent floods, ensure water security, optimize water resource allocation and promote water environment improvement.

[0003] The main goals of smart hydrology construction include data sharing, decision support, risk early warning, and resource optimization. To achieve these goals, existing technologies generally employ the following methods and techniques: 1. Data acquisition and transmission; 2. Data analysis and modeling; 3. Intelligent monitoring and early warning systems; 4. Smart management and optimization.

[0004] Due to the extreme cold of winter in frigid regions, rivers and lakes freeze severely, and prolonged periods of low temperatures often result in thick ice layers forming on their surfaces, with extreme thicknesses reaching up to 3.0 meters. These thick ice layers pose significant challenges to the collection and transmission of river and lake flow data, thereby hindering the development of smart hydrology systems.

[0005] Based on the aforementioned environmental problems, the applicant previously filed a utility model patent, authorized announcement number CN117705170B, filed on December 12, 2023, for an integrated hydrological monitoring device that can automatically prevent freezing in winter in high-altitude and cold regions. This device can meet the requirements of hydrological monitoring in winter in high-altitude and cold regions.

[0006] Therefore, based on the above-mentioned technical problems, there is an urgent need in this field to develop a device that is based on the current hydrological monitoring devices and improves them to be suitable for hydrological monitoring cylinders in frigid regions where the water inside does not freeze and is disturbed.

[0046] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0047] See Figures 1 to 11 As shown;

[0048] The anti-icing device of the hydrological monitoring system in cold regions during winter in this embodiment is integrated into the hydrological monitoring cylinder 100.

[0049] Anti-freezing devices include:

[0050] The water disturbance device has an outlet located in the water inside the hydrological monitoring cylinder 100. The water disturbance device continuously supplies water into the water inside the hydrological monitoring cylinder 100 through the outlet to disturb the water inside the hydrological monitoring cylinder 100.

[0051] Specifically, this embodiment discloses an anti-freezing device based on a hydrological monitoring cylinder 100. This anti-freezing device is mainly used to continuously disturb the water inside the hydrological monitoring cylinder 100 to ensure that the water inside the cylinder does not freeze. Therefore, the main design of this embodiment is to integrate a disturbance device inside the hydrological monitoring cylinder 100, and to continuously output water through an outlet 101 placed inside the water body of the water temperature monitoring cylinder 100 to achieve the design purpose of disturbing the water body. The principle of preventing freezing by continuously disturbing the water body has been repeatedly proposed by the applicant in previous applications; therefore, its principle will not be repeated here.

[0052] Preferably, based on the structure of the hydrological monitoring cylinder 100, the hydrological monitoring cylinder 100 in this embodiment is divided into an upper cylinder 11 and a lower cylinder 12;

[0053] The cross-sectional dimensions of the upper cylinder 11 are larger than those of the lower cylinder 12.

[0054] When the water inside the hydrological monitoring cylinder 100 is disturbed, the lower cylinder 12 is embedded inside the ice layer 200, and the lower surface of the upper cylinder 11 contacts the upper surface of the ice layer 200.

[0055] This embodiment is mainly based on the structural feature that the upper cylinder 11 of the hydrological monitoring cylinder 100 is larger than the lower cylinder 12. The lower cylinder 12 is embedded into the ice layer 200 as a whole, while the upper cylinder 11 is attached to the ice layer 200 to support the entire device.

[0056] To further improve the anti-freezing effect, a cylinder insulation layer 13 is provided between the lower cylinder 12 and the ice layer 200 in this embodiment.

[0057] See Figures 2 to 8 As shown, the preferred embodiment is the first implementation method of this example:

[0058] The first implementation of the water disturbance device in this embodiment is: the water disturbance device adopts a submersible pump 1;

[0059] The submersible pump 1 is integrated inside the lower cylinder 12 via a linear slide 2, and the depth of the submersible pump 1 is adjusted via the linear slide 2.

[0060] First, a linear slide 2 is installed inside the lower cylinder 12. The linear slide 2 generally includes a drive motor, a mounting platform fixed to the inner wall of the lower cylinder 12, and a lead screw connected to the output end of the drive motor. The submersible pump 1 is connected to the lead screw by a submersible pump mounting base and a slider. When the lead screw rotates under the drive of the drive motor, the slider can convert the rotational motion into the linear motion of the slider due to the threaded connection with the lead screw, thereby realizing the deep adjustment of the submersible pump 1.

[0061] As a preferred embodiment, the outlet 101 of the submersible pump 1 in this embodiment is arranged horizontally, inclined, or vertically upward. It can be seen that, according to different requirements, there are various arrangements of the outlet 101 of the submersible pump 1 in this embodiment.

[0062] When the outlet 101 of the submersible pump 1 is tilted, the outlet 101 of the submersible pump 1 is tilted upward or downward.

[0063] Based on the ambient temperature and the volume of water inside the cylinder, a submersible pump with suitable head and flow rate is selected to generate a flow field intensity that meets the anti-icing requirements. The submersible pump 1 is driven by a variable frequency motor to adjust the flow intensity, but a conventional motor can also be used. The above describes the integration of the submersible pump in an adjustable manner using a linear slide. However, in this embodiment, the submersible pump can also be integrated directly inside the lower cylinder 12 in a fixed manner, i.e., the mounting base can be directly fixed inside the lower cylinder 12.

[0064] Preferably, in this embodiment, the outlet 101 of the submersible pump 1 is oriented along the circumferential tangent of the lower cylinder 12.

[0065] In this embodiment, the outlet direction of the submersible pump 1 is along the tangent direction of the cylinder circumference, which achieves better flow field intensity under the same power conditions.

[0066] See Figure 9 and Figure 10As shown in the preferred embodiment, the submersible pump's outlet is angled downwards at 45°, and the outlet is tilted towards the side closest to the cylinder wall, with an angle of 5° between the outlet and the vertical. The most preferred configuration in this embodiment is a 45° downward tilt and a 5° tangential angle along the cylinder wall. This arrangement utilizes the Coanda effect to convert limited pump power into high-intensity three-dimensional vortex flow, a core optimization strategy. This arrangement creates full-section circulation, inducing a rotating flow field and increasing vortex intensity by 30%. Centrifugal force is used to throw the central water body towards the cylinder wall, eliminating the central stagnant zone. The outlet is positioned 20-25 cm below the water surface to maximize disturbance to the frozen water surface, while the intake is located at the bottom of the cylinder to draw in warmer water from the river, improving ice-prevention efficiency and effectiveness.

[0067] Power-flow matching calculation for this arrangement:

[0068] Given: submersible pump power P = 84W, water density ρ = 1000kg / m³, and maximum flow rate Q = 0.00069 m³ / s.

[0069] Initial jet velocity: Vjet≥√(2P / ρQ), substituting the data, we get Vjet≥15.6m / s.

[0070] Compared to random arrangement, this scheme can increase the average kinetic energy inside the cylinder by 50%, reduce the volume of the dead water zone to less than 5%, and maintain the water surface in an unfrozen state at -25℃.

[0071] See Figure 11 As shown, the preferred embodiment is the second implementation method of this example:

[0072] In the second embodiment, the water disturbance device is a centrifugal pump 3;

[0073] Centrifugal pump 3 is arranged inside the upper cylinder 11, and centrifugal pump 3 has an inlet pipe and an outlet pipe;

[0074] The inlet 102 of the inlet pipe passes through the lower cylinder 12 and extends to the lower part of the interior of the lower cylinder 12, while the outlet 101 of the outlet pipe passes through the lower cylinder 12 and extends to the upper part of the interior of the lower cylinder 12.

[0075] In this embodiment, the centrifugal pump 3 is placed inside the upper cylinder 11, and the inlet 102 is placed in the water at the bottom of the lower cylinder 12 via a pipeline. The outlet is arranged in the water at the top of the lower cylinder 12 via a pipeline. The arrangement of the outlet 101 of the centrifugal pump 3 in this embodiment is the same as that of the submersible pump 3 in embodiment one, and will not be described again here.

[0076] Preferably, the submersible pump 1 in this embodiment is powered by 48V, 24V, or 12V.

[0077] Preferably, the centrifugal pump 3 in this embodiment is powered by 48V, 24V, or 12V.

[0078] In the above technical solution, the present invention provides a device for preventing water disturbance inside a hydrological monitoring cylinder in extremely cold regions from freezing, which has the following beneficial effects:

[0079] The device of this utility model integrates a disturbance device, such as a submersible pump 1 or a centrifugal pump 3, inside the hydrological monitoring cylinder 100 using an integrated frame; the disturbance device continuously disturbs the water body after reaching a certain water level to achieve the effect of preventing ice formation.

[0080] The device of this invention employs a method of disturbing the water inside the cylinder to create a flow field. Within this flow field, ice nuclei are less likely to form, or any existing ice nuclei are eliminated by the flow field. According to relevant literature, without ice nuclei, the water temperature will not freeze even below 0°C. Secondly, this application draws in water from outside the cylinder, where the water temperature may be higher than that inside the cylinder, thus utilizing this temperature difference.

[0081] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
