Description

Technical Field

[0001] The present invention relates to the technical field of ice layer measurement, and more particularly to an ice thickness measurement device for a floating platform type ice temperature temperature chain. Background Art

[0002] Field prototype observations of river ice, lake ice and reservoir ice layer conditions are important means to clarify ice-water dynamics and ice-water coupling mechanisms, and also the basis for ice prevention and disaster reduction. Ice thickness and water depth are important observation parameters in prototype ice observations, and are of great significance for evaluating the safety of river-blocking buildings, the stability of revetments, and ice prevention and disaster reduction.

[0003] During the ice layer formation process and after its formation, two types of forces, static ice pressure and dynamic ice pressure, are exerted on hydraulic structures, which is a special form of damage to hydraulic structures in cold regions in the north. At the same time, the ice layer thickness is also an important parameter that determines the ice breakup time and ablation state, and plays an important role in flood control and ice prevention.

[0004] Therefore, it is necessary to study the laws of ice layer generation, disappearance and change in order to achieve the purpose of disaster reduction. The ice layer thickness is the most significant feature of ice layer generation, disappearance and change, and is the main physical parameter for studying ice layers. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides an ice thickness measurement device for a floating platform type ice temperature temperature chain.

[0006] The technical solution of the present invention is: an ice thickness measurement device for a floating platform type ice temperature temperature chain, including a bracket, an ice temperature temperature chain for measuring the longitudinal temperature gradient of the ice temperature holes in the reservoir ice layer profile, a floating platform and a chassis,

[0007] The bracket includes a support rod, two first support rods arranged at both ends of the support rod in the horizontal direction, and a second support rod arranged in the middle of the support rod in the vertical direction. The two first support rods and the second support rod are perpendicular to the support rod,

[0008] There are two floating platforms, which are respectively arranged along the length direction of the first support rod and fixedly connected to the first support rod. The chassis is arranged on the second support rod and fixedly connected to the second support rod. A connecting plate for fixing the ice temperature temperature chain is provided on the second support rod,

[0009] The ice temperature temperature chain is composed of a plurality of temperature sensors and a cable for connecting the plurality of temperature sensors in series,

[0010] Inside the chassis, there are a data collector for receiving ice temperature chain monitoring data, a power supply battery, and a DTU module for transmitting the data collected by each temperature sensor. The power supply battery is connected to the ice temperature chain, the data collector, and the DTU module respectively through wires. The data collector is connected to the ice temperature chain through a data cable, and the DTU module is connected to the data collector through a data cable.

[0011] Furthermore, the temperature sensor is detachably connected to the cable, and the ice temperature chain is subjected to sealing and waterproof treatment, and the scale and the positions of the temperature nodes are marked on the outside of the ice temperature chain.

[0012] Note: By performing sealing and waterproof treatment on the ice temperature chain, the working stability of the ice temperature chain can be effectively improved, and the normal operation of the ice temperature chain under the ice can be avoided. By marking the scale and the positions of the temperature nodes on the outside of the ice temperature chain, it is convenient to observe the positions of the various temperature sensors of the ice temperature chain and the specific depth of the ice temperature chain inserted into the ice temperature hole, thus laying a prerequisite for the temperature measurement work.

[0013] Furthermore, the temperature sensor is a digital temperature sensor; the cable is a polyurethane cable, and a plurality of the temperature sensors are connected in an SDI-12 bus mode using one such cable. The output signal of the ice temperature chain is in the standard international hydrographic SDI-12 interface protocol.

[0014] Note: The ice temperature chain is connected in an SDI-12 bus mode, which does not occupy the analog input channels of the data collector. The ice temperature chain uses the standard international hydrographic SDI-12 interface protocol, which can be applicable to the collection of most current data collectors, thereby improving the compatibility with market data collectors. It is very simple to use and can easily form a temperature acquisition system or network based on the SDI-12 bus with market data collectors.

[0016] Note: The chassis is also additionally equipped with a GPS module and an atmospheric temperature and humidity sensor, which can provide a reliable means for the continuous monitoring of the ice thickness, growth and decay of rivers, lakes and reservoirs, and the time evolution of the multi-year cycle. Its low cost allows for the deployment of multiple units in an array to improve the spatial variability data;

[0017] The data collected by ice thickness gauges are very suitable for evaluating process models, for example, determining ice-water energy exchange, for weather forecasting in extremely cold regions, and for monitoring ice thickness and state in rivers and lakes. Ice thickness gauges can also be used to monitor snowmelt and changes in structural snowpack in mountainous areas.

[0018] As an optional solution of the present invention, the temperature sensor is connected to the cable via a cable tie.

[0019] Note: Connecting the temperature sensor to the cable with a cable tie is low cost, simple to connect and easy to operate.

[0021] The loading slot is provided with a sinking slot which is slidably connected to the driving plate, and a gear set which is rotatably connected to the driving plate is provided in the sinking slot, and the gear set is composed of a first gear and a second gear which are arranged from bottom to top, and the first gear and the second gear are fixedly connected through a shaft, and the first gear is located in the strip-shaped hole and is meshed and transmission-connected with the first rack.

[0022] A second rack meshing with the second gear is respectively provided on the loading slot located at the front and rear sides of the second gear, and the two second racks are slidably connected to the loading slot and penetrate through the side walls of the loading slot and are fixedly connected to the first supporting plates corresponding thereto, and a cover plate for covering the second rack and the driving plate is provided in the loading slot, and the cover plate is detachably connected to the loading slot;

[0023] A ratchet wheel component capable of adjusting the forward and reverse rotation of the ratchet wheel is respectively provided at the left and right ends of the second support plate, and a slide groove for moving the ratchet wheel component is respectively provided on the side walls on both sides of the loading slot, a spur gear is provided at the output end of the ratchet wheel component, and a third rack for meshing with the spur gear is provided in the slide groove.

[0024] Description: The locking carrier can provide a new locking method for the temperature sensor to be mounted on the cable. It can be applied to cables of various specifications and sizes, thus providing greater freedom in the selection of multi-core cables. It is also easy to disassemble and assemble, and is convenient for maintenance and replacement of local temperature sensors. The locking carrier is reusable, which is more economical and can reduce the problem of temperature sensor offset on the cable.

[0025] Further, a third support plate is provided at the rear side of the second support plate and is arranged parallel to the second support plate. A plurality of first airbag columns are arranged between the third support plate and the second support plate, and the third support plate is slidably connected to the driving plate.

[0026] On the opposite side surfaces of the two first support plates, a plurality of groups of locking members are provided, and on the opposite side surfaces of the two first support plates, storage grooves for storing the locking members are provided.

[0027] The locking member includes two groups of locking rods and an anti-slip rod. One ends of the two groups of locking rods are rotatably connected to the anti-slip rod through a rotating shaft, and a guide rod rotatably connected thereto is provided at the other end of the locking rod. The guide rod is slidably connected to the storage groove. The locking rod is hollow inside, and a slider slidably connected thereto is provided inside the locking rod. One end of the slider is provided with a spring connected to one end inside the locking rod. A guide strip with a trapezoidal cross-section is arranged along the length direction inside the locking rod. A plurality of anti-slip convex points for using the slider to move out of the locking rod are provided on the guide strip. A plurality of the anti-slip convex points are all arranged on the guide strip, and holes corresponding to the anti-slip convex points are provided on the locking rod.

[0028] The other end of the slider is provided with a connecting rope fixedly connected to the inner wall of the storage groove. A strip-shaped groove for moving the connecting rope is provided on the side wall of the locking rod. A second airbag column for contacting the corresponding guide rod on one side is provided at the inner end of the storage groove. The second airbag column is communicated with the first airbag column through a conduit.

[0029] Explanation: By setting the third support plate, the first and second airbag columns, and the locking members, the two groups of first support plates can provide further locking and clamping for the cable, thereby further preventing relative misalignment with the cable and avoiding the problem of deviation of the temperature nodes set by the temperature sensor. And through the structural setting of the locking member, the kinetic energy of its outward expansion is used to control the anti-slip convex points on the guide strip to protrude and contact the cable, which ensures locking while not affecting the ease and convenience of disassembly.

[0030] The present invention also provides a method for measuring ice thickness by using an ice thickness measuring device, including the following steps:

Set the spacing of each temperature sensor of the ice temperature temperature chain. 40 cm of the upper part of the ice temperature temperature chain is exposed in the air, and a temperature sensor for measuring the air temperature is set every 20 cm. The middle and lower parts of the ice temperature temperature chain are immersed 160 cm under the ice. In the 0 - 120 cm section under the ice of the ice temperature temperature chain, a temperature sensor for measuring the temperature in the water body or ice body is set every 3 cm. In the 120 - 160 cm section under the ice of the ice temperature temperature chain, a temperature sensor for measuring the temperature in the water body or ice body is set every 10 cm.

[0032] S2. Drill ice temperature holes in the ice layer of the reservoir, place the ice temperature chain into the ice temperature holes, and keep the ice thickness measuring device stable on the ice surface through a floating platform and a bracket;

[0033] S3. Each temperature sensor obtains temperature data of the air or different ice layers and transmits it to the data collector through a cable. The data collector records and stores the data and transmits the data to the data server through the DTU module for analysis. The thickness of the ablation of the reservoir ice layer is judged according to the different temperatures of the temperature sensors at different nodes of the ice temperature chain in the air and different ice layers.

Detailed implementation manners

[0054] The present invention will be further described in detail below in conjunction with specific embodiments to better reflect the advantages of the present invention.

[0055] Embodiment 1

[0056] As Figure 1 shown, an ice thickness measuring device for a floating ice-temperature temperature chain includes a bracket 1, an ice-temperature temperature chain 2 for measuring the longitudinal temperature gradient of the ice-temperature holes in the reservoir ice layer profile, a floating platform 3, and a chassis 4.

[0057] The bracket 1 includes a support rod 11, two first support rods 12 arranged at both ends of the support rod 11 in the horizontal direction, and a second support rod 13 arranged in the middle of the support rod 11 in the vertical direction. The two first support rods 12 and the second support rod 13 are both perpendicular to the support rod 11.

[0058] There are two floating platforms 3, and the two floating platforms 3 are respectively arranged along the length direction of the first support rod 12 and fixedly connected to the first support rod 12. The chassis 4 is arranged on the second support rod 13 and fixedly connected to the second support rod 13. A connecting plate 14 for fixing the ice-temperature temperature chain 2 is provided on the second support rod 13.

[0059] The ice-temperature temperature chain 2 is composed of 47 temperature sensors 22 and a cable 21 for connecting the 47 temperature sensors 22 in series. As Figure 2 shown, the temperature sensors 22 are connected to the cable 21 through cable ties, and the ice-temperature temperature chain 2 is sealed and waterproofed with a cable sheath. Only the temperature measuring probe of the temperature sensor 22 penetrates through the cable sheath, and the scale and the position of the temperature node are marked on the outside of the ice-temperature temperature chain 2. The ice-temperature temperature chain selects DS18B20 digital temperature sensors. The cable 21 is a polyurethane cable, and 47 temperature sensors 22 are connected in an SDI-12 bus mode using one cable 21. The output signal of the ice-temperature temperature chain 2 is in the standard international hydrological SDI-12 interface protocol.

[0060] The chassis 4 is equipped with a data collector for receiving the monitoring data of the ice temperature chain 2, a power supply battery, a DTU module for transmitting the data collected by each temperature sensor 22, and a GPS module for the ice movement of rivers, lakes and reservoirs. The upper end of the second rod 13 is sleeved with a radiation shield. An atmospheric temperature and humidity sensor for obtaining local ambient air temperature and humidity data is provided on the second rod 13 below the radiation shield. The power supply battery is respectively connected to the ice temperature chain 2, the data collector, the DTU module, the GPS module, and the atmospheric temperature and humidity sensor through wires. The data collector is connected to the ice temperature chain 2, the atmospheric temperature and humidity sensor, and the GPS module through data lines. The DTU module is connected to the data collector through a data line. Among them, the atmospheric temperature and humidity sensor selects the Model HC2S3 air temperature and humidity sensor, the data collector selects the G30 series ultra-low power data collector, and the GPS module selects the SKYLAB SKG12BL GPS module.

[0061] The measurement method using the above ice thickness measurement device includes the following steps:

[0062] S1. Set the spacing of each temperature sensor 22 of the ice temperature chain 2. As Figure 3 shown, 40 cm of the upper part of the ice temperature chain 2 is exposed in the air, and a temperature sensor 22 for measuring air temperature is set every 20 cm. The middle and lower parts of the ice temperature chain 2 are immersed 160 cm under the ice. In the section of 0-120 cm under the ice of the ice temperature chain 2, a temperature sensor 22 for measuring the temperature in the water body or ice body is set every 3 cm. In the section of 120-160 cm under the ice of the ice temperature chain 2, a temperature sensor 22 for measuring the temperature in the water body or ice body is set every 10 cm;

[0063] S2. Drill an ice temperature hole in the ice layer of the reservoir, and place the ice temperature chain 2 into the ice temperature hole. The ice thickness measurement device is kept stable on the ice surface through the floating platform 3 and the bracket 1;

[0064] S3. The temperature data of the air or different ice layers obtained by each temperature sensor 22 is transmitted to the data collector through the cable 21, recorded and stored by the data collector, and the data is transmitted to the data server for analysis through the DTU module. According to the different temperatures of the temperature sensors 22 at different nodes of the ice temperature chain 2 in the air and different ice layers, the ablation thickness of the reservoir ice layer is judged;

[0065] Specifically, the above ice thickness measurement device is used to monitor the dynamic change process of the winter ice thickness in a reservoir area in Xinjiang. As Figure 3Currently, three sets of ice temperature chains are installed in a reservoir area in Xinjiang to monitor the ice thickness change and dynamic process of the reservoir and for demonstration applications. Based on summarizing relevant operating parameters, research is conducted on the installation, commissioning, operation, maintenance, and evaluation criteria of the data acquisition network.

[0066] Monitoring results: Through the monitoring of a reservoir area in Xinjiang from December 16, 2021, to March 31, 2022, temperature gradient data of the air-ice-snow-water layer were obtained.

[0067] 1) Freezing period:

[0068] Linear: h i = β F × AFDD γ ; where β F and γ are coefficients, and AFDD is the accumulated ice period.

[0069] Non - linear: h i = Δh i + h i-1 where Δh i is non - linearly related to the underwater temperature; h = f(T a , C, L) is a machine learning algorithm.

[0070] 2) Ice melting period:

[0071] where ATDD is the accumulated ice melting days.

[0072] Through the above calculations, the change in the ice thickness of the reservoir measured by the ice temperature chain is finally converted, and at the same time, it is compared with the manually measured value. As Figure 4 shown, it can be seen that the ice thickness measuring device of the present invention can accurately monitor the dynamic change process of the winter ice thickness in a reservoir area in Xinjiang.

[0073] Embodiment 2

[0074] The difference between this embodiment and Embodiment 1 is that, as Figure 5 shown, the temperature sensor 22 is connected to the cable 21 through the locking carrier 5.

[0075] As Figure 6 shown, the locking carrier 5 includes a carrier slot 51 for buckling the temperature sensor 22, two first support plates 52, and a second support plate 53. The two first support plates 52 are arranged in parallel on the left and right sides of the carrier slot 51 and are perpendicular to the carrier slot 51. The second support plate 53 is arranged on the bottom surface of the carrier slot 51 and is perpendicular to the bottom surface of the carrier slot 51. A driving plate 54 perpendicular to the second support plate 53 is provided on the second support plate 53. A strip - shaped hole 541 is provided on the driving plate 54, and a first rack 542 is provided on one inner wall of the strip - shaped hole 541.

[0076] As Figure 7 、 8 shown, a sunk groove 511 slidably connected to the driving plate 54 is provided on the carrier groove 51. A gear set 55 rotatably connected thereto is provided in the sunk groove 511. The gear set 55 is composed of a first gear 551 and a second gear 552 arranged from bottom to top. The first gear 551 and the second gear 552 are fixedly connected by a shaft rod. The first gear 551 is located in the strip-shaped hole 541 and is meshed and drivingly connected with the first rack 542.

[0077] As Figure 5 shown, a second rack 553 meshed and drivingly connected with the second gear 552 is provided on each of the front and rear sides of the carrier groove 51 where the second gear 552 is located. The two second racks 553 are slidably connected to the carrier groove 51 and penetrate through the side walls on both sides of the carrier groove 51 and are fixedly connected to the corresponding first support plates 52. A cover plate 59 for covering the second rack 553 and the driving plate 54 is provided in the carrier groove 51. The cover plate 59 is detachably connected to the carrier groove 51;

[0078] As Figure 6 shown, a ratchet member 56 capable of adjusting the forward and reverse rotation of the ratchet is provided at each of the left and right ends of the second support plate 53. The ratchet member 56 is adjusted in shape by using a commercially available adjustable ratchet wrench to be adapted and installed in this device. A sliding groove 512 for the movement of the ratchet member 56 is provided on each of the side walls of the carrier groove 51. A spur gear is provided at the output end of the ratchet member 56. A third rack 513 for meshing with the spur gear is provided in the sliding groove 512.

[0079] The usage method of the above-mentioned locking carrier 5 is as follows:

[0080] The temperature sensor 22 used in this device is of a strip-shaped structure. If a temperature sensor 22 of other shapes is adapted and installed, a strip-shaped plate needs to be assembled as a substrate;

[0081] One side of the locking carrier 5 provided with two first support plates 52 is buckled on the cable 21. Subsequently, the temperature sensor 22 is pushed forcefully into the carrier groove 51 along the upper end of the carrier groove 51 as shown in Figure 5 . The temperature sensor 22 is clamped by the protrusions on the upper end part of the inner wall of the carrier groove 51.

[0082] During the process of pushing the temperature sensor 22 into the carrier groove 51, the temperature sensor 22 pushes the second support plate 53 to move, thereby causing the driving plate 54 to move. Through the meshing and driving action of the first rack 542 and the first gear 551, the gear set 55 rotates, thereby causing the second gear 552 to rotate. Under the meshing and driving action of the second gear 552 and the two second racks 553, the two first support plates 52 gather towards the cable 21 side, thereby clamping the cable 21.

[0083] Meanwhile, during the process of pushing the temperature sensor 22 into the carrier slot 51, due to the action of the ratchet member 56, the spur gear rotates forward. When the cable 21 is clamped, due to the action of the ratchet member 56, the spur gear rotates backward and locks. Under the meshing action with the third rack 513, as Figure 5 shown, it cannot move upward.

[0084] When it is necessary to take out the temperature sensor 22, just switch the forward and reverse locking of the two groups of ratchet members 56 first, and then as Figure 5 shown, push the temperature sensor 22 upward to release the connection between the temperature sensor 22 and the cable 21.

[0085] Embodiment 3

[0086] This embodiment is further set on the basis of Embodiment 2. Specifically: as Figure 9 、 10 、11 shown, a third support plate 57 parallel to the rear side of the second support plate 53 is provided. There are 5 first airbag columns 571 between the third support plate 57 and the second support plate 53, and the third support plate 57 is slidably connected to the drive plate 54.

[0087] As Figure 10 、 12 、13 shown, 8 groups of locking members 58 are provided on the opposite side surfaces of the two first support plates 52. The number of locking members 58 provided depends on the length of the first support plate 52. The length of the first support plate 52 is 1.5 times the diameter length of the cable 21, and storage grooves 521 for storing the locking members 58 are provided on the opposite side surfaces of the two first support plates 52.

[0088] As Figure 14 、 15 shown, the locking member 58 includes two groups of lock rods 581 and an anti-slip rod 587. One ends of the two groups of lock rods 581 are rotatably connected to the anti-slip rod 587 through a rotating shaft, and a guide rod rotatably connected thereto is provided at the other end of the lock rod 581. The guide rod is slidably connected to the storage groove 521. The lock rod 581 is hollow inside, and a slider 582 slidably connected thereto is provided inside the lock rod 581. One end of the slider 582 is provided with a spring 583 connected to one end inside the lock rod 581. A guide strip 584 with a trapezoidal cross-section is provided along the length direction inside the lock rod 581. There are 5 anti-slip bumps on the guide strip 584 for using the slider 582 to move out of the lock rod 581. The 5 anti-slip bumps are all provided on the guide strip 584, and holes corresponding to the anti-slip bumps are provided on the lock rod 581.

[0089] As Figure 10 、 13As shown, a connecting rope 585 fixedly connected to the inner wall of the storage groove 521 is provided at the other end of the slider 582. A strip-shaped groove for moving the connecting rope 585 is provided on the side wall of the locking rod 581. A second air bag column 586 for contacting the corresponding guide rod on one side is provided at the inner end of the storage groove 521. The second air bag column 586 is communicated with the first air bag column 571 through the inner air passage of the first support plate 52, the second telescopic hose, the inner air passage of the carrier groove 51, and the first telescopic hose in sequence.

[0090] The usage method of the above-mentioned locking carrier 5 is as follows:

[0091] Based on the usage method of Embodiment 2, as shown in Figure 9 During the process of pushing the temperature sensor 22 into the carrier groove 51, the temperature sensor 22 pushes the third support plate 57 to move towards the second support plate 53, squeezing each first air bag column 571, so that the gas enters the inner air passage of the carrier groove 51 from the first telescopic hose and enters the inner air passage of the first support plate 52 through the second telescopic hose, and the gas is sent to each second air bag column 586 through the inner air passage of the first support plate 52;

[0092] Under the push of the second air bag column 586, the ends of the two locking rods 581 of the locking member 58 with guide rods are gathered, so that one side of the anti-slip rod 587 fits against the cable 21. Since Figure 8 the lowermost locking member 58 is located below the cable 21, the anti-slip rod 587 of this locking member 58 can be moved directly below the cable 21, and the cable 21 can be wrapped around 360° by the cooperation of the two locking rods 581 of this locking member 58.

[0093] At the same time, during the unfolding process of the locking member 58, under the pulling of the connecting rope 585, the slider 582 of the locking rod 581 of the locking member 58 slides, stretching the spring 583 and pushing the guide bar 584, so that the anti-slip protrusions of the guide bar 584 extend to increase the friction force with the cable 21.
