Abstract
Description
Technical Field
[0001] This invention relates to an apparatus and method for preparing strip ice for ice ridge experiments, belonging to the field of ice engineering technology. Background Technology
[0002] Ice ridges are raised sections on the upper and lower surfaces of sea ice formed by the breaking up of ice blocks of varying sizes and shapes under the influence of environmental dynamics such as wind, currents, and waves, resulting from overlapping and compression. They are mainly composed of a ridge sail and a keel. The study of the physical properties of ice ridges is an indispensable part of fundamental research in ice mechanics. According to ITTC specifications, the preparation of ice ridges requires stacking strips of ice together to simulate the ridge sail and keel structure.
[0003] The strip ice required for ice ridges is prepared by cutting frozen layers of ice, which is typically done in an ice-water bath. Cutting strip ice in an ice-water bath requires cutting over a wide area, and traditional cutting methods cannot accurately cut strips of ice of uniform width, making the operation difficult. Furthermore, due to the low temperature of the ice-water bath, the cutting time is also critical; if the cutting time is too long, the cut will refreeze, affecting the accumulation of the strip ice and consequently the preparation of the ice ridge. Currently, research on ice ridges in China is limited, and there is no dedicated strip ice cutting device for the ice ridge preparation process. Summary of the Invention
[0004] This invention provides a mechanical device for cutting layers of ice to obtain a large number of ice strips of equal width, which is characterized by simple operation, rapid cutting and easy disassembly.
[0005] The objective of this invention is achieved as follows: it includes a trailer, a motor mounted on the trailer, a main drive belt mechanism mounted on the output end of the motor, a driven support mounted on the trailer, a follower drive belt mechanism mounted on the driven support, a lifting support located in the middle of the trailer, a lifting bushing mounted on the lifting support, and a lifting shaft located inside the lifting bushing. A cutting shaft is provided between the output wheels of the main drive belt mechanism and the follower drive belt mechanism. Cutting blades are provided at equal intervals on the cutting shaft. A lifting handwheel is provided at the upper end of the lifting shaft, and the lower end is connected to the cutting shaft via a bearing.
[0006] The present invention also includes the following structural features:
[0007] 1. The trailer includes a trailer frame, trailer cable, and trailer wheels.
[0008] 2. A method for cutting strip ice for ice ridge experiments.
[0009] The first stage is the preparation stage: drive the trailer to the area where the ice layer needs to be prepared, clear the area around the cutting blade into an open water state, adjust the lifting handwheel to put the two transmission belt mechanisms in a tensioned state, and start the motor after the adjustment is completed.
[0010] The second stage is the operation stage: After the motor runs smoothly, the trailer is started, and the entire system begins to cut the ice. The trailer moves at a constant speed, and the ice layer is cut into strips of ice of equal width.
[0011] The third stage is the cleaning stage: After the trailer moves to the target distance, the motor is turned off. After the system has completely stopped, the lifting handwheel is adjusted to clean up the ice debris around the cutting shaft.
[0012] Compared with existing technologies, the advantages of this invention are: it significantly improves the efficiency of strip ice preparation at a lower cost. This invention is a device designed for preparing strip ice in ice ridge experiments, and there are currently no related patents with similar specifications. This invention is simple to operate and requires inexpensive consumables. Furthermore, this invention can be used at low temperatures. Taking into account the impact of freezing on the system, the lifting system can promptly remove ice frozen around the cutting shaft 18, allowing for extended operation at low temperatures after timely removal.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0018] This invention proposes a mechanical device for cutting layered ice to obtain a large number of uniformly wide strips of ice. It mainly consists of a trailer system, a motor 7, a cutting shaft 17, and a cutting blade 11. A tow cable 1 is connected to a trailer frame 2. The tow cable 1 pulls the trailer, causing the trailer wheels 10 to rotate, and the entire trailer begins to move. The motor 7 is fixed to the trailer frame 2 by a support 18. The motor 7 is directly connected to a drive wheel 8. When the motor 7 starts, the drive wheel 8 rotates, driving the cutting shaft 17 and the cutting blade 11 to rotate together via a transmission belt 9. The cutting shaft 17 passes through a bearing 13 and is secured with bolts 14. A lifting shaft 15 is fixed at the top, passing through a lifting shaft sleeve 12. A lifting handwheel 5 is located at the top, and rotating the lifting handwheel 5 raises and lowers the lifting shaft 15. The lifting shaft sleeve 12 is fixed to a lifting support 6, which is bolted to the trailer frame 2.
[0019] The lifting handwheel 5 can adjust the height of the cutting shaft 17 when rotated. The lifting handwheel 5 can also control the tension of the transmission belt 9. When the work is completed, the lifting handwheel can be rotated to raise the cutting shaft 17 and remove the frozen ice around the shaft and the cutting blade 11. In addition, the cutting shaft can be separated from the lifting shaft 15 by removing the fixing bolt 14.
[0020] Cutting blades 11 are arranged at equal intervals on the cutting shaft 17. The rotation of the cutting shaft 17 drives the cutting blades 11 to rotate, and the trailer moves forward to start the cutting operation.
[0021] The device for improving the flatness of overlapping ice surfaces is used in three stages:
[0022] The first stage is the preparation stage: drive the trailer to the area where the ice layer needs to be prepared, clear the area around the cutting blade 11 into an open water state, adjust the lifting handwheel 5 to make the transmission belt 9 taut, and start the motor 7 after adjustment.
[0023] The second stage is the operation stage: after motor 7 is running smoothly, the trailer is started, and the entire system begins to cut. The trailer moves at a constant speed, and the ice layer is cut into strips of ice of equal width.
[0024] The third stage is the cleaning stage: After the trailer moves to the target distance, turn off motor 7. After the system stops completely, adjust the lifting handwheel 5 and clean up the ice fragments around the cutting shaft 17.
[0025] exist Figure 1In the process, the towing cable 1 is connected to the trailer frame 2. The towing cable 1 pulls the trailer, causing the trailer wheels 10 to rotate, and the entire trailer begins to move. The driven shaft support 3 supports the driven wheel 4. The driven wheel 4 is connected to the cutting shaft 17 via a transmission belt. The lifting bushing 12 is fixed to the lifting support 6, which is bolted to the trailer frame 2. Rotating the lifting handwheel 5 drives the lifting shaft 15, which in turn drives the cutting shaft 17 to achieve lifting and lowering. The cutting shaft 17 is connected to the lifting shaft 15 via a fixing bolt 14, which is fixed to a bearing 13. The cutting shaft 17 has a cutting blade 11. When the cutting shaft 17 rotates, it drives the cutting blade 11 to rotate, thus performing the cutting operation.
[0026] exist Figure 2 In this system, motor 7 is directly connected to drive wheel 8. Drive wheel 8 drives cutting shaft 17 via transmission belt 9, which in turn drives cutting blade 11 to rotate. Cutting shaft 17 passes through bearing 13. Bearing 13 is fixed below by fixing bolt 14, and lifting shaft 15 is fixed above it. Lifting shaft 15 passes through lifting bushing 12, and a lifting handwheel 5 is located at the top. Rotation of lifting handwheel 5 raises and lowers lifting shaft 15. Lifting bushing 12 is fixed to lifting support 6, which is bolted to trailer frame 2. Driven wheel 4 is connected to cutting shaft 17 via follower transmission belt and output pulley. Rotation of cutting shaft 17 drives driven wheel 4 to rotate. The rotation of driven wheel 4 ensures the dynamic balance of the entire system.
[0027] exist Figure 3 In the process, tow cable 1 is connected to trailer frame 2. Tow cable 1 pulls the trailer, causing trailer wheels 10 to rotate, and the entire trailer begins to move. Motor 7 is fixed to trailer frame 2 by support 18. Motor 7 is directly connected to drive wheel 8. Drive wheel 8 drives cutting shaft 17 to rotate via transmission belt 9 and output wheel. Cutting shaft 17 passes through bearing 13. Bearing 13 is fixed below by fixing bolt 14, and lifting shaft 15 is fixed above by it. Lifting shaft 15 passes through lifting shaft sleeve 12, and a lifting handwheel 5 is provided at the top. Rotating lifting handwheel 5 raises and lowers lifting shaft 15. Lifting shaft sleeve 12 is fixed to lifting support 6, and lifting support 6 is fixed to trailer frame 2 by bolts.
