Description
Technical Field
[0001] The invention relates to the technical field of ice layer detection, and in particular to a pneumatic detection device for ice development in a channel under the influence of multiple factors. Background Art
[0002] Due to the lack of channel ice condition detection equipment. Nowadays, channel ice condition detection data still relies on artificial drilling or ice drilling. There are few observation data, and it is impossible to monitor the thickness of the ice body in real time. In addition, the influence of variable factors such as temperature, humidity, wind direction, and wind speed on ice development is ignored. It is difficult to obtain ice development records under multiple influencing factors. The flow rate, temperature, and salt content of water under the ice surface also have a very important influence on the freezing and thawing of the ice body. Channel flow, wind force and direction and other factors are the main factors in the formation of ice floods. Real-time monitoring of ice freezing and thawing can effectively prevent the occurrence of ice floods.
[0003] With the advancement of science and technology and the emphasis on ice safety in various fields, ice detection technology has been continuously improved, and a variety of detectors and detection equipment based on different detection principles have been developed. The main methods for detecting ice thickness in industry are: radar technology, acoustic wave technology, optical method, electrical method and mechanical method, etc. Many ice measuring devices have low stability in complex environments, weak anti-interference ability, and may have errors in measurement results. In addition, the equipment cost is high, the operation is cumbersome, and the factors affecting ice formation are not fully considered. For example, ice detection technology based on image recognition is easily affected by factors such as light, resulting in reduced measurement accuracy.
[0004] At present, most ice development test devices are self-made. Patent CN101221036A uses the principle of electrical capacitance tomography to detect ice thickness. Changes in ion concentration in water will increase the error of the instrument, and it fails to consider the relationship between river flow rate, humidity and ice development. Patent CN116399276A uses ice drilling measurement, which has large errors and cannot detect ice layer changes in real time. For this reason, we have launched a pneumatic detection device for ice development in channels under the influence of multiple factors. Summary of the invention

[0043] The present invention adopts non-contact real-time monitoring technology for lateral displacement of ice bodies, avoiding sensor damage or measurement errors that may be caused by direct contact. This non-contact measurement method improves the reliability and durability of the system, and can monitor and accurately record the lateral displacement of ice bodies in the channel in real time.

First, the real-time collection and feedback mechanism ensures the timeliness of the data, and the flexible design allows the equipment to adapt to different environmental conditions and meet diverse measurement needs. In addition, the high-precision air resistance ice measurement method and non-contact real-time monitoring technology of ice lateral displacement not only improve the measurement accuracy, but also maintain stability in extreme weather. The combination of automation and multi-parameter monitoring greatly reduces the need for manual intervention, improves work efficiency, and makes the response to environmental changes more rapid and comprehensive.

[0087] After receiving the signal, the signal processor 104 controls the heating controller 201 through the first PLC controller 101 to adjust the temperature of the heating tube 902 and the heater 901;
[0088] The model of the heating controller 201 is Honeywell 900U02-0100, Honeywell 900U01-0100 or other models that meet the use requirements.
[0089] The temperature and humidity detector 208 is used to detect the temperature and humidity of the air;
[0090] The pressure gauge 205 is electrically connected to the second PLC controller 202 . The second PLC controller 202 is used to process the data transmitted by the pressure gauge 205 and transmit the data back via the signal processor 104 .
[0091] The model of pressure gauge 2051 is YK-100B or other models that meet the use requirements.
[0092] The model of the pressure gauge 205 is a HAKK-YBS-2S digital pressure gauge or other models that meet the use requirements.
[0093] The air inlet pipe 204 is connected to the air inlet of the peristaltic pump 203, and the air outlet of the peristaltic pump 203 is connected to a plurality of groups of detection tubes 209. The upper part of the detection tubes 209 is provided with a pressure gauge 205 and a pressure gauge 2051. The bottom ends of the detection tubes 209 extend into the heating tube 902, and the bottom ends of the detection tubes 209 are arranged in sequence up and down (i.e., closely arranged longitudinally) and then extend from the inner wall of the heating tube 902.

[0096] The heating tube 902 and the heater 901 melt the ice around them (the temperature is controlled at 0-5°C) to prevent the ice layer development detector 9 from losing its mobility due to the adhesion of ice.
[0097] The heating tube 902 is used to melt the ice in the detection tube 209 (the temperature is controlled at 0-5°C) to ensure that the ice does not block the inside of the detection tube 209;
[0098] The model of peristaltic pump 203 is BT100-3J or other models that meet the usage requirements.
[0099] The peristaltic pump 203 compresses the gas in the air inlet pipe 204 into the detection tube 209. Since the gas flow compressed into each detection tube 209 is the same, the type of medium at the end of the detection tube 209 is determined according to the different resistances generated by air, ice and water to the end of the detection tube 209, thereby achieving the purpose of detecting the thickness of the ice layer.
[0100] The ice body development lateral displacement detector 20 is used to detect the lateral movement of the ice body in the channel to collect the lateral displacement data of the ice body;
[0101] like Fig.14 As shown, the ice body development transverse displacement detector 20 includes a T-groove rod 16 fixed to the middle of the equipment main frame 14, a slider 19 arranged in the T-groove of the T-groove rod 16, a metal rod 18 arranged on the slider 19, and a displacement detector 17;
[0102] The model of the displacement detector 17 is a laser displacement sensor of brands such as Keyence and Omron, or other models that meet the use requirements.
[0103] During the development of ice in the channel, the ice squeezes each other, causing the ice to drive the metal rod 18 to produce lateral displacement. The displacement of the metal rod 18 drives the slider 19 to slide on the T-groove rod 16. The displacement detector 17 on the slider 19 detects the lateral displacement of the ice during the development of the ice, and transmits the data to the signal processor 104 through the first PLC controller 101, and transmits the data back through the signal processor 104.
[0104] The size and quantity of the non-contact ice lateral displacement real-time monitoring module (i.e., ice lateral displacement detector 20) used in the present invention are not limited to Fig.14 As shown in , it can be adjusted according to actual situation.
[0105] The detection module is used to detect the wind speed and wind direction data in the channel, the flow velocity data of the water flow in the channel, the ion concentration data, the temperature data and the water level data, and the temperature data and the humidity data of the air;
[0106] The ice layer development detector 9 , the ice body development lateral displacement detector 20 and the detection module transmit the collected data to the signal processor 104 in the equipment box 1 .

[0108] The present invention uses a variety of detection sensors to detect the temperature, humidity, wind speed, wind direction, water salinity and other environments of the channel. By using the difference in resistance between air, ice and water to the detection outlet, a pressure gauge 205 is connected to the detection tube, and the air pressure is used to characterize the development of the ice body, thereby improving the accuracy and efficiency of ice monitoring. The law of channel ice development is explored by combining factors such as temperature, humidity, wind speed, wind direction, water salinity and so on.
[0109] The present invention designs a non-contact real-time monitoring technology for the lateral displacement of ice bodies, that is, the displacement information is transmitted through the physical contact between the metal rod and the ice body, and the displacement detector 17 itself does not directly contact the ice body, thereby avoiding sensor damage or measurement errors that may be caused by direct contact. The displacement detector 17 can monitor and accurately record the lateral displacement caused by the interaction of the ice body in real time. The device is specially designed to adapt to special environments and can accurately detect the lateral development of the ice body in the channel, which is conducive to analyzing the damage factors of the channel under lateral action.
[0110] In order to minimize the interference of the detection process on the development of natural ice, the present invention adopts advanced signal control technology and refined electric heating strategy to achieve micro-melting of the ice around the ice layer development detector, ensuring that the normal operation of the detection device is not affected by the attachment of ice.
[0111] In the present invention, the wind speed detector 5, the wind direction detector 6, the flow velocity detector 7, the temperature and humidity detector 208, and the ice layer development detector 9 are electrically connected to the first PLC controller 101. The signal processor 104 performs signal control on the detection box 2, the mechanical guide rail assembly 3, the wind speed detector 5, the wind direction detector 6, the flow velocity detector 7, the temperature and humidity detector 208, the ice body development lateral displacement detector 20, and the ice layer development detector 9 by connecting to the first PLC controller 101, thereby realizing high-speed data transmission and execution of control instructions.

[0121] At the same time, the signal processor 104 receives real-time data from the wind speed detector 5, wind direction detector 6, flow rate detector 7, temperature and humidity detector 208, ice body development lateral displacement detector 20 and ice layer development detector 9, and realizes the detection and transmission of temperature, humidity, wind speed, wind direction, water salinity and other data in the channel environment through various detectors on the equipment and the signal processor 104.
[0122] After receiving the signal, the signal processor 104 controls the heating controller 201 through the first PLC controller 101 to adjust the temperature of the heating tube 902 and the heater 901, melt the ice around the ice layer development detector 9 and the mouth of the detection tube 209 to prevent the mouth of the detection tube 209 from freezing before the detection, and realize the up and down movement detection of the equipment without interfering with the detection, thereby ensuring the flexibility of the equipment.
[0123] The signal is transmitted to the signal processor 104 through the signal antenna 106 for processing, and the lifting controller 206 is controlled by the first PLC controller 101 to start the lifting motor 207 and control the rotation direction of the driving gear of the lifting motor 207, thereby controlling the up and down movement of the detection box 2 and the ice layer development detector 9.
[0124] The power of the lifting motor 207 is transmitted to the gear guide rail 301 through the meshing of the driving gear. As the lifting motor 207 is started, the sliding seat 15 connected thereto and the partition plate 303 and the detection box 2 thereon also begin to move. After the ice layer development detector 9 is moved to the specified position, the lifting controller 206 is turned off to stop the movement of the equipment.
[0125] Four peristaltic pumps 203 are placed in the detection box 2. A pressure gauge 205 and a pressure gauge 2051 are set on each detection tube 209. Each pressure gauge 205 is connected to the second PLC controller 202 to process the data transmitted by the pressure gauge 205. The detection tube 209 is set in the heating tube 902, and the tube mouth of the detection tube 209 protrudes from the heating tube 902.
[0126] When the ice layer development detector 9 reaches the designated position, the heater 901 and the heating tube 902 are stopped. The first PLC controller 101 is used to control the peristaltic pump 203 to start working, and the gas in the air inlet pipe 204 is compressed into the detection tube 209. Since the gas flow compressed into each detection tube 209 is the same, the resistance of air, ice and water to the detection outlet is different, so the type of medium at the mouth of the detection tube 209 is determined to achieve the purpose of detecting the thickness of the ice layer. The detection tube 209 is connected with a pressure gauge 205 to receive the pressure of the detection tube 209, calculate the thickness of the ice layer, and use the data transmitted by the water level detector 12 to calculate the flow of water under the ice in the channel and the distance between the ice layer and the water surface. All the data in the pressure gauge 205 are transmitted to the second PLC controller 202 and converted into relevant information of the ice layer, and the detection results are transmitted back through the signal processor 104.
[0127] Each peristaltic pump 203 is provided with 15 detection tubes 209, the diameter of which is set to 5 mm and arranged closely in the longitudinal direction to improve the detection accuracy. The detection tubes 209 are arranged in the heating tube 902 to ensure that the ice in the tube opening of the detection tube 209 melts when the heating tube 902 is heated. The tube opening of the detection tube 209 protrudes from the heating tube 902 to ensure that the detection tube 209 can contact the ice.
[0128] The driving mechanism drives the ice layer development detector 9 below the detection box 2 to a designated position, so that the detection tube 209 on the ice layer development detector 9 can detect the thickness of the ice body.

[0130] The slider 19 moves, and the work starts after adjusting the plurality of sliders 19 to a reasonable interval.
[0131] During the development of ice in the channel, the ice squeezes each other, causing the ice to drive the metal rod 18 to produce lateral displacement, and the displacement of the metal rod 18 drives the slider 19 to slide on the T-groove rod 16. The displacement detector 17 on the slider 19 detects the lateral displacement of the ice during the development of the ice, transmits the data to the signal processor 104 through the first PLC controller 101, and transmits the data back through the signal processor 104.
[0132] Specifically, when using, (1) check the equipment wires, signal processing devices and equipment connections, and adjust the equipment;
[0133] (2) Using the signal to control the first PLC controller 101, the data detected by the detection module is transmitted back through the signal processor 104, and the system records the transmitted data;
[0134] (3) using the transmitted signal to determine the approximate position of the water flow, using the first PLC controller 101 to control the heating controller 201, so that the heating tube 902 and the heater 901 are heated to slightly melt the surrounding ice (the heating temperature is 0-5°C), turning on the lifting controller 206, and the lifting motor 207 moves the detection tube 209 to the ice layer position;
[0135] (4) After the position is adjusted, turn off the heating tube 902 and the heater 901;
[0136] (5) After the device is left to stand for a period of time, when the ice body grows and freezes the mouth of the detection tube 209, the peristaltic pump 203 is turned on to inflate the detection tube 209, and the second PLC controller 202 is used to process the data transmitted by the pressure gauge 205. After the pressure value stabilizes, the value is recorded, and the peristaltic pump 203 is turned off after the value collection is completed;
[0137] (6) Repeat the operation in (5) at regular intervals;
[0138] (7) After the experiment is completed, all instruments are turned off through the first PLC controller 101.
