[0046] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0047] Referring to Figures 1 to 11 shown;

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

[0049] The anti-icing device comprises:

[0050] The water body disturbance device has a water outlet in the water in the hydrological monitoring cylinder 100, and the water body disturbance device continuously transports water to the water in the hydrological monitoring cylinder 100 through the water outlet to disturb the water body in the hydrological monitoring cylinder 100.

[0051] Specifically, the embodiment discloses an anti-freezing device based on a hydrological monitoring cylinder, which is mainly used for continuously disturbing water in the hydrological monitoring cylinder 100 to ensure that the water in the hydrological monitoring cylinder 100 will not freeze. Therefore, the main design scheme of the embodiment is to integrate a disturbing device in the hydrological monitoring cylinder 100, and continuously output water through the water outlet 101 placed in the water in the hydrological monitoring cylinder 100 to achieve the design purpose of disturbing the water. The principle that the water is continuously disturbed to prevent freezing has been proposed many times in the applicant's previous applications, so the principle will not be described here.

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

[0053] The cross-sectional size of the upper cylinder 11 is greater than that of the lower cylinder 12.

[0054] When the device is used to disturb the water in the hydrological monitoring cylinder 100, the lower cylinder 12 is embedded in the ice layer 200, and the lower surface of the upper cylinder 11 contacts the upper surface of the ice layer 200.

[0055] The 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, and the lower cylinder 12 is embedded in the ice layer 200, and the upper cylinder 11 is lapped on the ice layer 200 to support the entire device.

[0056] In order to further improve the anti-freezing effect, the lower cylinder 12 of the embodiment is provided with a cylinder heat preservation layer 13 between the lower cylinder 12 and the ice layer 200.

[0057] Referring to Figures 2 to 8 The first embodiment of the embodiment is as follows:

[0058] The first embodiment of the water disturbing device of the embodiment is that the water disturbing device adopts a submersible pump 1.

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

[0060] First, the linear slide 2 is arranged in the lower cylinder 12, and the linear slide 2 generally includes a driving motor, a mounting table fixed to the inner wall of the lower cylinder 12, and a lead screw connected with the output end of the driving motor; and the submersible pump 1 is threadedly connected with the lead screw through a submersible pump mounting seat and a sliding block. When the lead screw rotates under the driving of the driving motor, the sliding block can convert the rotary motion into the linear motion of the sliding block due to the threaded connection with the lead screw, so as to realize the deep adjustment of the submersible pump 1.

[0061] As a preferred embodiment, the water outlet 101 of the submersible pump 1 is horizontally arranged or the water outlet 101 of the submersible pump 1 is obliquely arranged or the water outlet 101 of the submersible pump 1 is vertically upward arranged; it can be seen that the arrangement form of the water outlet 101 of the submersible pump 1 of the embodiment has multiple forms according to different requirements.

[0062] Among them, when the water outlet 101 of the submersible pump 1 is obliquely arranged, the water outlet 101 of the submersible pump 1 is obliquely upward or obliquely downward.

[0063] According to the ambient temperature and the volume of water in the cylinder, the submersible pump with suitable head and flow is selected to generate a flow field strength that meets the anti-icing requirements. Among them, the submersible pump 1 drive adopts a variable frequency motor to adjust the flow process strength, and the conventional motor drive mode can also be used. The above introduces the submersible pump integrated in an adjustable way through a linear sliding table, and the embodiment can also be integrated in a fixed way directly in the lower cylinder 12, that is, the mounting seat is directly fixed in the lower cylinder 12.

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

[0065] And the outlet direction of the submersible pump 1 of the embodiment is along the circumferential tangent direction of the cylinder, and under the condition of the same power, a better flow field strength is obtained.

[0066] Referring to Figure 9 and Figure 10 As a preferred embodiment of the embodiment, the water outlet arrangement angle of the submersible pump of the embodiment is 45° downward, and the water outlet of the submersible pump is inclined toward the side of the cylinder wall close to it, and the angle between the water outlet and the vertical line is 5°. The most preferred way of the embodiment is that the water outlet of the submersible pump is inclined downward by 45°, and at the same time, it is arranged along the tangential direction of the cylinder wall by 5°. By this arrangement, the impact on the cylinder wall is the core optimization strategy for converting limited pump power into high-strength three-dimensional rotational flow through the Coanda effect. This arrangement form will form a full-section circular flow, induce a rotating flow field, and increase the vortex intensity by 30%. The centrifugal force will throw the central water body to the cylinder wall, eliminating the central stagnant flow area. The water outlet is arranged at a depth of 20-25 cm below the water surface, maximizing the disturbance of the ice water surface, and the suction port is arranged at the bottom of the cylinder to absorb the water with a higher temperature in the river channel, improving the ice prevention efficiency and effect.

[0067] The power-flow matching calculation of this arrangement form is as follows:

[0068] It is known that the submersible pump power P = 84w, the water density p = 1000kg / m³, and the maximum flow of the submersible pump Q = 0.00069 m³ / s.

[0069] The jet initial velocity is Vjet≥sqrt(2P / pQ), and the data can be obtained as Vjet≥15.6 m / s.

[0070] Compared with the random arrangement, the scheme can increase the average kinetic energy in the cylinder by 50%, reduce the dead water volume to less than 5%, and maintain the water surface in an ice-free state at an environment of-25 DEG C.

[0071] Referring to Figure 11 As shown, preferably, the second embodiment of the embodiment is:

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

[0073] The centrifugal pump 3 is arranged in the upper cylinder body 11, and the centrifugal pump 3 has a water inlet pipe and a water outlet pipe.

[0074] The water inlet 102 of the water inlet pipe penetrates the lower cylinder body 12 and extends below the inside of the lower cylinder body 12, and the water outlet 101 of the water outlet pipe penetrates the lower cylinder body 12 and extends above the inside of the lower cylinder body 12.

[0075] The centrifugal pump 3 of the second embodiment is placed in the upper cylinder body 11, and the water inlet 102 is placed in the water in the lower part of the lower cylinder body 12 by a pipeline, and the outlet is arranged in the water in the upper part of the lower cylinder body 12 by a pipeline. The arrangement of the water outlet 101 of the centrifugal pump 3 of the embodiment is the same as that of the water outlet 101 of the submersible pump 3 in the first embodiment, which will not be described again.

[0076] Preferably, the power supply voltage of the submersible pump 1 of the embodiment is 48V or 24V or 12V.

[0077] Preferably, the power supply voltage of the centrifugal pump 3 of the embodiment is 48V or 24V or 12V.

[0078] In the above technical solution, the water body disturbance device provided by the application in the hydrological monitoring cylinder in the cold region has the following beneficial effects:

[0079] The device of the application is integrated with a disturbance device such as a submersible pump 1 or a centrifugal pump 3 in the hydrological monitoring cylinder 100, and the disturbance device is continuously disturbed after being deeply immersed in a certain water level to achieve the effect of preventing ice formation.

[0080] The device of the application adopts the method of disturbing the water body in the cylinder to form a flow field, and the water body in the flow field is not easy to form ice nuclei or the formed ice nuclei are eliminated by the flow field. According to the relevant literature, under the condition of no ice nuclei, the water temperature will not freeze even below 0 DEG C. Secondly, the application inhales the water outside the cylinder, and the water in this area may be higher in temperature than the water in the cylinder to obtain the temperature difference.

[0081] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application. The appended drawings and description are illustrative only, and are not intended to be limiting.
