Description

Technical Field

[0001] The invention relates to the technical field of high-speed water jet ice breaking, and in particular to an experimental device for jet cutting ice bodies under long target distance submerged conditions. Background Art

[0002] With global warming and the melting of ice sheets, the opening of polar shipping routes and resource exploration have become possible, but the existence of sea ice makes polar operations too difficult. At present, the research on the mechanical deformation mechanism and interaction force of ice is still immature, and a complete, efficient and feasible polar icebreaking technology system has not yet been formed. The main icebreaking methods currently used include blasting icebreaking, mechanical icebreaking, icebreaker collision and other methods, but these methods have problems such as environmental pollution and low efficiency, and have certain limitations.

[0003] Water jet technology is mainly used in mining, tunnel construction and other fields. It uses high-pressure jets of fluid to cut and crush rocks. Compared with traditional blasting and mechanical crushing methods, water jet rock breaking technology has the advantages of small environmental impact, precise control, and high work efficiency. In the polar marine environment, the huge impact force generated by high-speed water jets can cause ideal controllable destruction to large blocks of ice, and the water for the jet can be replenished at any time. Therefore, water jet technology can be used as a new means in the field of icebreaking, which requires a set of jet icebreaking experimental equipment that can adjust different experimental parameters under submerged and non-submerged working conditions, so as to facilitate the study of water jet icebreaking modes and destruction mechanisms.

[0004] After searching, the existing Chinese invention patent with an application date of 2019.08.20 and an application number of 201910767721.8 discloses an experimental device for high-speed water jet icebreaking experiments. The device can analyze the influence of different parameters on the damage characteristics of ice plates during the coupling of high-speed water jets and ice surfaces. In addition, the existing Chinese utility model patent with an application date of 2023.03.31 and an application number of 202320684811.2 discloses an experimental device for high-speed water jet icebreaking experiments. The device can analyze the magnitude of the force on the ice surface during the impact, the damage to the ice surface when the ice surface bends or shears under different parameters, and the generation and expansion of cracks. However, after research, the inventors of this application found that these two experimental devices are small in scale and cannot provide a long target distance submerged experimental environment.

Therefore, after the experiment is completed, the drain valve 17 is opened, and the liquid in the submerged chamber can be quickly discharged through the drain port 15 and the drain pipe 16 to prevent blockage.

[0030] As a specific example, please refer to Figure 1 As shown, the load-bearing platform includes a load-bearing plate 21 for supporting a large submersion chamber.

The load-bearing seats 22 are used to support the weight of the entire experimental device. Load-bearing columns 23 for supporting the mobile system are fixed to the four corners of the surface of the load-bearing plate 21.

[0031] As a specific example, please refer to Figure 1 and Figure 3 As shown, the target loading system includes a hollow target box 31, and a transparent glass is also arranged on the front of the target box 31, that is, the front of the target box 31 adopts the same transparent acrylic glass as the wall of the submerged cavity, so as to facilitate observation of the target 35; a top plate 32 is fixed on the top of the target box 31, and a lifting ring 33 is connected to the top plate 32, so that the entire target box 31 can be moved by the lifting ring 33 in cooperation with a crane or a crane; a bottom plate 34 is fixed on the lower part of the target box 31, and the bottom plate 34 is fixedly arranged on the top of the large submerged cavity, and specifically, the bottom plate 34 is fixed to the bearing plate 13 of the large submerged cavity, and the target 35 is clamped and loaded inside the target box 31, and a second cutting groove 341 is opened on the bottom plate 34 below the target 35 to facilitate the jet to act on the target 35, and the second cutting groove 341 is the same size as and opposite to the first cutting groove 131 on the bearing plate 13, so as to facilitate the jet to act on the target 35.

[0034] As a specific example, please refer to Figure 1 and Figure 4 As shown, the mobile system includes a crossbeam 40 and a control box 41 fixed on the load-bearing platform. Specifically, the crossbeam 40 and the control box 41 are fixed to the load-bearing column 23 of the load-bearing platform. The crossbeam 40 is arranged on the top of the load-bearing column 23, and the control box 41 is attached to the left side wall of the load-bearing column 23. The crossbeam 40 is provided with a lateral moving component 42 that can move left and right relative to the crossbeam 40.

A nozzle holder 44 is fixedly provided at the bottom of the up-and-down moving assembly 43, and a nozzle 46 and a jet pipeline 47 connected to the inside of the nozzle are provided on the nozzle holder 44 through a nozzle fixing bolt 45. A controller 48 is provided in the box 41, and the controller 48 is electrically connected to the lateral moving component 42 and the up-and-down moving component 43 through a line (specifically, it is electrically connected to the servo motor in the lateral moving component 42 and the cylinder in the up-and-down moving component 43) to control the movement of the components. The controller 48 can be specifically implemented by an existing PLC controller, that is, the specific control method of the controller 48 for the servo motor and the cylinder is well known to those skilled in the art. Under the control of the controller 48, the lateral moving component 42 can drive the up-and-down moving component 43 to move left and right on the beam 40 to drive the nozzle 46 to move left and right. At the same time, the up-and-down moving component 43 can drive the nozzle 46 to move up and down through the cylinder, and the left-and-right movement range of the lateral moving component 42 (adjusting the cutting speed) and the up-and-down movement range of the up-and-down moving component 43 (adjusting the jet target distance) are both not less than 1000mm, and the moving distance and moving speed can be adjusted by the controller 48, that is, the left-and-right movement speed of the nozzle 46, that is, the cutting speed parameter, can be controlled by the controller 48 during the jet cutting process, and the cutting range is not less than 1000mm.

That is, the emergency stop valve 49 is connected to the power supply of electrical equipment such as servo motors and cylinders. When an accident occurs and the entire equipment needs to be stopped immediately, the power supply of the device can be immediately disconnected through the emergency stop valve 49, which effectively ensures the safety of the entire experiment.

[0037] In order to better understand the experimental device for jet cutting ice under long target distance submerged conditions provided by the present invention, the specific working mode of the device is introduced as follows:

[0038] First, connect the jet pipeline 47 and the nozzle 46 and fix them on the nozzle holder 44, and adjust the nozzle incident angle according to the experimental needs by loosening the screws; after the nozzle 46 is connected, use the external water pipe to inject water into the large submerged cavity to the required water level, and connect the power supply to power on the entire device; remove the fixing bolts 36 of the bottom plate 34, use the crane to tighten the lifting ring 33, and hang the target box 31 from just above the large submerged cavity, remove the fixing bolts 36 of the top plate 32, pull up the pull ring 33, open the top plate 32, place the target 35 in the target box 31, and clamp it with the pull rod 38 and the rigid clamping plate 37, and cover it. The top plate 32 is tightened, and the top plate fixing bolts 36 are tightened. The hoisting hoisting ring 33 is lifted to the upper part of the large submerged chamber. At this time, the second cutting groove 341 in the target box 31 must be aligned with the first cutting groove 131 on the carrier plate 13 so that the jet can act on the target 35. The bottom plate fixing bolts 36 are tightened to fix the position of the target box 31. The controller 48 set in the control box 41 is used to adjust the height of the up-down moving assembly 43 according to the required jet target distance, and the nozzle holder 44, the nozzle 46 and the jet pipeline 47 are driven to move to the target position together. At this time, the controller 48 is operated to move the horizontal moving assembly 42 Move to the leftmost end of the large submerged chamber and prepare to start the experiment; after the preparation is completed, turn on the existing jet pump connected to the jet pipeline 47 to generate the jet. After the pressure stabilizes, operate the controller 48 to set the right movement speed of the lateral moving component 42. At this time, the lateral moving component 42 drives the up-down moving component 43, the nozzle holder 44, the jet pipeline 47 and the nozzle 46 to move to the right together. The set right movement speed of the lateral moving component 42 is also the movement speed of the jet cutting the ice body. After the up-down moving component 43 moves to the rightmost end of the large submerged chamber, operate the controller 48 to stop the movement. This process If any unexpected situation occurs, the emergency stop valve 49 can be pressed to disconnect the power supply of the entire equipment; after the cutting experiment is completed, stop the jet, use the crane to tighten the lifting ring 33, lift the target box 31 from just above the large submerged chamber, remove the top plate fixing bolts 36, open the top plate 32, pull the pull ring 39 to loosen the rigid clamping plate 37, take out the target 35, observe and record the experimental data; after the experiment is completed, open the drain valve 17, and the liquid in the large submerged chamber can flow through the drain port 15 through the drain pipe 16 and be quickly discharged. After the discharge, clean the cavity and perform regular maintenance on each system equipment in preparation for the next experiment.

[0039] The advantages of the present invention are: 1) the experimental environment is controllable: the amount of water injected into the submerged chamber can be determined according to needs, and the submerged or non-submerged experimental environment can be freely controlled; 2) the experimental scale is large: a large block of ice, i.e., a target body, can be placed in the target box, and the jet target distance and the nozzle movement range can both move within a large range, which can meet the requirements of long target distance and large-scale experiments; 3) the experimental conditions are controllable: the controller can be adjusted according to needs to determine whether the nozzle moves to achieve jet impact or cutting experiments; 4) the safety of the device is guaranteed: fixing bolts are set on the contact part between the target box and the submerged chamber and the top plate to prevent the target box from being opened or water splashing due to excessive jet pressure, and an emergency stop valve is also set to disconnect the power supply of the device at any time.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
