The construction of intelligent hydrology is of great significance to the sustainable development of modern society, and it can improve the water resource management ability, prevent floods, ensure water safety, optimize water resource allocation, and promote water environment improvement.

[0003] The goals of the construction of intelligent hydrology mainly include data sharing, decision support, risk warning, and resource optimization.

[0054] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0055] See Figures 1 to 8 Shown;

[0056] A device for measuring flow rate in winter in cold regions in this embodiment, the device includes:

[0057] Integrated cylinder assembly 100;

[0058] The integrated cylinder assembly 100 internally integrates a flow measurement instrument;

[0059] The flow measurement instrument is arranged inside the integrated cylinder assembly 100 through a height adjustment structure, and the inside of the integrated cylinder assembly 100 forms a non-freezing area. The flow measurement instrument is placed underwater inside the integrated cylinder assembly 100 and measures the flow rate at this place.

[0060] Specifically, this application is a device improved for measuring flow in winter in cold regions based on an integrated hydrological monitoring device that can automatically prevent freezing in winter in cold regions in the applicant's prior application. The main body of the device is the integrated cylinder assembly 100 in the prior application, and a flow measurement instrument is integrated inside the integrated cylinder assembly 100 through a height adjustment structure. The flow measurement instrument is lowered and extended into the water through the height adjustment structure. Due to the existence of the integrated cylinder assembly 100, a static water area can be formed between the ice layers, and it is ensured that the water in this part does not freeze. At the same time, considering the technological requirements for measuring flow, it is necessary to use the height adjustment structure to lower and extend the flow measurement instrument into the water below the ice layer to measure the flow velocity in this area, so as to finally obtain the flow value.

[0061] Preferably, the flow measurement instrument in this embodiment is a horizontal acoustic Doppler current profiler 401, a rotor current meter 403, or an ultrasonic Doppler lead fish 402.

[0062] As an extended explanation, the flow measurement instruments involved in this application are all off-the-shelf components, and their models are as follows:

[0063] The horizontal acoustic Doppler current profiler 401 is selected from: Guangzhou Zhonghaida Satellite Navigation Technology Co., Ltd., model: iFlow RH600;

[0064] The rotor current meter 403 is selected from: Chongqing Huazheng Hydrological Instrument Co., Ltd., model: LS68;

[0065] The ultrasonic Doppler lead fish 402 is selected from: Tangshan Modern Industrial Control Technology Co., Ltd., model: XD-2306-QY-QD.

[0066] See Figures 1 to 3 As shown in the following, Embodiment 1:

[0067] This Embodiment 1 discloses the first implementation manner of this application, that is, the structure in which the flow measurement instrument selects a horizontal acoustic Doppler current profiler 401. Specifically, when the flow measurement instrument in this Embodiment 1 selects a horizontal acoustic Doppler current profiler 401, the horizontal acoustic Doppler current profiler 401 adjusts the depth of penetration into the water through the height adjustment structure;

[0068] The height adjustment structure includes:

[0069] A linear module 1 fixed to the inner wall of the integrated cylinder assembly 100; and

[0070] A rotating mechanism 2 slidably connected to the linear module 1 through a slider 203. The rotating mechanism 2 has a rotating shaft 204 extending in the vertical direction, and a horizontal acoustic Doppler current profiler 401 is installed at the lower end of the rotating shaft 204;

[0071] The linear module drives the rotating mechanism 101 to move in the vertical direction to adjust the depth of the rotating mechanism 2 and the horizontal acoustic Doppler current profiler 401 immersed in water;

[0072] The horizontal acoustic Doppler current profiler 401 adjusts its orientation through the rotating mechanism 2.

[0073] Wherein, the linear module 1 of the first embodiment is fixed to the inner wall of the integrated cylinder assembly 100 through the linear module mounting seat 104;

[0074] The upper end of the linear module 1 is provided with a linear module servo motor 101. A driving lead screw 102 is connected to the output end of the linear module servo motor 101. Slide rails 103 are arranged on both sides of the driving lead screw 102 of the linear module 1;

[0075] Both sides of the slider 203 are slidably connected to the slide rails 103, and the middle part of the slider 203 is threadedly connected to the driving lead screw 102 to convert the rotational motion of the driving lead screw 102 into the linear motion of the slider 203;

[0076] The rotating mechanism 2 includes:

[0077] A rotating mechanism cylinder body 201 connected to the slider 203;

[0078] A rotating mechanism servo reduction motor 202 integrated at the upper end of the rotating mechanism cylinder body 201. The output end of the rotating mechanism servo reduction motor 202 is connected with a rotating shaft 204;

[0079] The rotating shaft 204 is rotatably connected to the rotating mechanism cylinder body 201 through a bearing.

[0080] The horizontal acoustic Doppler current profiler 401 of the first embodiment utilizes the linear module 1 and the rotating mechanism 2 as height adjustment structures and integrates them inside the integrated cylinder assembly 100. The linear module 1 drives the driving lead screw 102 to rotate with the linear module servo motor 101 as the power source. Since the middle part of the slider 203 is threadedly connected to the driving lead screw 102, the rotational motion of the driving lead screw 102 is converted into the linear motion of the slider 203. The slide rails 103 play a guiding role for the slider 203 and finally drive the entire rotating mechanism 2 to reciprocate in the vertical direction to adjust the appropriate height. Secondly, the rotating mechanism 2 of the first embodiment uses the rotating mechanism servo reduction motor 202 as the driving structure, which drives the rotating shaft 204 to rotate to adjust the orientation of the horizontal acoustic Doppler current profiler 401.

[0081] See Figures 4 to 8 As shown in the figure, the second embodiment:

[0082] The second embodiment discloses the second implementation of the present application, that is, the specific structure when the rotor type flow meter 403 and the ultrasonic Doppler lead fish 402 are respectively used as the flow measurement instrument. When the flow measurement instrument of this embodiment uses the rotor type flow meter 403 or the ultrasonic Doppler lead fish 402, the rotor type flow meter 403 or the ultrasonic Doppler lead fish 402 adjusts the depth of penetration into the water through the height adjustment structure;

[0083] The height adjustment structure is a hoisting and lifting mechanism 3, which drives the cable core steel wire rope 306 thereon to rise and fall; the lower end of the cable core steel wire rope 306 is connected to a rotor flow meter 403 or an ultrasonic Doppler lead fish 402.

[0084] The hoisting and lifting mechanism 3 of the second embodiment includes:

[0085] A mounting base 301 fixed to the inner wall of the integrated cylinder assembly 100, and a reinforcing rib 307 is provided at the lower portion of the mounting base 301;

[0086] A hoist 302 is arranged on the mounting base 301, a conductive slip ring 304 is arranged at one end of the hoist 302, and a hoist servo reduction motor 303 is connected to the other end of the hoist, and the hoist servo reduction motor 303 is connected to the central axis of the hoist 302 through a bearing in a bearing seat 305;

[0087] The installation base 301 reserves a passage for the cable core steel wire rope 306 to pass through, and the cable core steel wire rope 306 extends from the passage to the bottom of the installation base 301 .

[0088] The second embodiment mainly discloses the technology of using the hoisting lifting mechanism 3 as the height adjustment structure. The hoisting lifting mechanism 3 is driven to move by the hoisting machine servo reduction motor 303. In order to supply power to the flow measuring instrument at the lower end, the present embodiment adopts a cable wire rope 306 and a conductive slip ring 304. The height adjustment of the flow measuring instrument at the lower end can be achieved by retracting and releasing the cable wire rope 306, and the electrical connection requirements of the instrument can be met.

[0089] As the third embodiment of the present application, when the flow measurement instrument uses a rotor flow meter 403, the lower end of the cable core steel wire rope 306 is connected to a lead fish 404, and the upper part of the lead fish 404 is connected to the rotor flow meter 403. The height adjustment structure of the third embodiment also adopts the hoisting lifting mechanism 3 in the second embodiment, so it is not repeated here.

[0090] In actual use, when the water surface of rivers and lakes freezes in winter and the ice layer has a certain bearing capacity, the integrated cylinder assembly 100 is embedded in the ice layer. The cross-sectional area of the end face at the equipment installation position can be obtained from the local hydrological department. Taking the first implementation mode as an example, during the non-measurement period, the horizontal acoustic Doppler profiler 401 is lifted above the interior of the integrated cylinder assembly 100 through the linear module 1 to avoid damage caused by foreign object piles in the river or lake. During the measurement period, the linear module 1 operates to lower the horizontal acoustic Doppler profiler 401 to an appropriate depth below the ice layer. Then the rotating mechanism 2 starts to operate to adjust the emitting surface of the horizontal acoustic Doppler profiler 401 to be perpendicular to the water flow direction. After the adjustment is completed, the measurement is carried out. When the measurement at this position is completed, the rotating mechanism 2 operates to rotate the horizontal acoustic Doppler profiler 401 by 180 degrees for measurement. After the entire measurement is completed, the rotating mechanism 2 continues to drive the horizontal acoustic Doppler profiler 401 to rotate back to the initial position. Finally, the linear module 1 lifts to store the horizontal acoustic Doppler profiler 401.

[0091] For the rotor current meter 403 and the ultrasonic Doppler lead fish 402 used as flow measurement instruments, the hoisting mechanism 3 is used to adjust the height. mainly by lowering the hoisting mechanism 3 to several different depths respectively for flow measurement, so as to achieve the purpose of accurate measurement values. Similarly, the same as in the first embodiment, during the non-measurement period, the hoisting mechanism 3 is also needed to recover the flow measurement instrument to avoid damage caused by impact of foreign objects in the water.

[0092] After the measurement, the electronic control system transmits the data to the user intelligent terminal through Ethernet and records it.

[0093] In the above technical solution, a device for measuring flow in winter in cold regions provided by the present utility model has the following beneficial effects:

[0094] The flow measurement device of the present utility model improves the integrated cylinder assembly 100, and integrates flow measurement instruments inside it through a height adjustment structure, so as to meet the requirements of measuring flow in rivers and lakes in cold regions in winter; this device solves the problems of difficult flow measurement, difficult data collection, and inability to transmit data in cold regions in winter. This device can monitor, collect, and transmit data in real time, and has high accuracy and strong practicability. It does not require manual participation and can better promote the development of intelligent hydrology construction.
