Description

Technical Field

[0001] The present invention relates to the technical field of ice harvesting, and particularly relates to a portable ice harvesting device. Background Art

[0002] An ice harvesting device is a device used to collect ice cubes from the river surface or lake surface. Its main function is to stably remove the ice cubes from the water surface and ensure that the ice cubes do not tilt or break away during the ice harvesting process. In polar scientific expeditions and glacier research, researchers need to collect glacier ice samples for analysis to understand the formation, evolution process of glaciers, and the impact of climate change on glaciers. The ice harvesting device can help scientific researchers collect ice samples at different depths and positions in polar or alpine glacier areas, providing important data support for research.

[0003] There will be a thin liquid water film on the surface of ice at low temperatures, which is formed by the interaction between the molecules on the ice surface and the external environment. This water film makes the surface of the ice relatively smooth and reduces the friction force. After the traditional ice harvesting device finishes collecting biological samples, even if the ice cube has a certain contact with surrounding objects, the small friction force is difficult to provide enough resistance to prevent the ice cube from sliding under the action of gravity. The sliding may cause the sample to break, deform or be damaged, affecting its integrity, and then interfering with the observation and analysis of the original characteristics and state of the sample. Re-collecting may face many difficulties, thus seriously delaying the progress of the entire research project. Based on the above problems, a portable ice harvesting device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and provide a portable ice harvesting device that can solve the problems in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A portable ice harvesting device includes a drill bit. The drill bit is hollow. A spiral rod is fixedly connected to the top of the drill bit. The spiral rod is hollow. A moving rod is spirally connected to the surface of the spiral rod. Anti-slip lines are provided on the surface of the moving rod. A push rod is slidably connected inside the spiral rod. A handle is provided at the top of the push rod. The push rod extends into the drill bit. A grinding column is fixedly installed inside the drill bit. One end of the push rod is slidably connected to the inside of the grinding column. Grinding teeth are provided on the surface of the grinding column. The grinding teeth are in the shape of sharp cones.

[0006] Preferably, an extrusion block is fixedly connected to one end of the push rod. A spring is movably sleeved on the surface of the push rod. One end of the spring is fixedly connected to the inner wall of the grinding column, and the other end of the spring is fixedly connected to the surface of the push rod.

[0007] Preferably, a support column is fixedly connected to the inner wall of the grinding column, a limiting plate is fixedly connected to the other end of the support column, and a sliding plate is slidably connected to the surface of the support column.

[0008] Preferably, an extrusion spring is movably sleeved on the surface of the support column. One end of the extrusion spring is fixedly connected to the inner wall of the grinding column, and the other end of the extrusion spring is fixedly connected to the surface of the sliding plate.

[0009] Preferably, a sliding groove is formed on the surface of the grinding column. A sliding rod is fixedly connected to the inside of the sliding plate. The sliding rod is inside the sliding groove. A conical thorn is fixedly connected to the surface of the sliding rod, and the surface of the sliding rod is slidably connected to the inside of the sliding groove.

[0010] Preferably, a rack is fixedly connected to the surface of the push rod. The rack is L-shaped and is divided into upper and lower sections. A rotating shaft is rotatably connected to the inner wall of the grinding column, and a winding wheel is fixedly connected to the surface of the rotating shaft.

[0011] Preferably, a support platform is fixedly connected to the inner wall of the grinding column. A fixed block is fixedly connected to the surface of the support platform. A return spring is movably sleeved on the surface of the fixed block. One end of the return spring is fixedly connected to the surface of the fixed block, and the other end of the return spring is fixedly connected to a sliding block. The surface of the fixed block is slidably connected to the inside of the sliding block.

[0012] Preferably, a rope is wound around the surface of the winding wheel. The rope is fixedly connected to the surface of the sliding block, and a hammer is fixedly connected to the surface of the sliding block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1). For this portable ice collection device, the sliding rod slides, causing the sliding plate to slide on the surface of the support column. As a result, the sliding plate squeezes the extrusion spring, causing it to deform. The conical thorn supports the ice block, preventing it from sliding down under the action of gravity. Such a slide may cause the sample to break, deform or be damaged, affecting its integrity, and thus interfering with the observation and analysis of the original characteristics and state of the sample. Re-collection may face many difficulties, leading to a serious delay in the progress of the entire research project. This improves the efficiency of sample collection.

[0015] (2). For this portable ice collection device, the vibration waves generated by the hammer hitting the support platform multiple times are transmitted to the entire inner wall of the grinding column. As a result, the inner wall of the grinding column vibrates, causing the ice block to slide out of the inside of the drill bit due to the vibration of being hit. This prevents the biological sample from not falling due to the resistance of the ice block itself or the inner wall of the drill bit, reducing the collection efficiency.

Detailed implementation manners

[0024] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to visually and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0025] Please refer to Figures 1-6 , the present invention provides a technical solution: a portable ice collection device, including a drill bit 1. The drill bit 1 is hollow. The top of the drill bit 1 is fixedly connected with a screw rod 3. The screw rod 3 is hollow. The surface of the screw rod 3 is helically connected with a moving rod 2. The surface of the moving rod 2 is provided with anti-slip lines. The inside of the screw rod 3 is slidably connected with a push rod 4. The top of the push rod 4 is provided with a handle. The push rod 4 extends into the inside of the drill bit 1. A polishing column 5 is fixedly installed inside the drill bit 1. One end of the push rod 4 is slidably connected with the inside of the polishing column 5. The surface of the polishing column 5 is provided with polishing teeth 6. The polishing teeth 6 are in a sharp cone shape.

[0026] When collecting glacier samples, the moving rod 2 slides on the surface of the screw rod 3, and the spiral shape drives the screw rod 3 to rotate. When the screw rod 3 rotates, it drives the drill bit 1 to rotate, so that the drill bit 1 drills holes in the ice surface. When the screw rod 3 rotates, it can drive the grinding column 5 to rotate, and the grinding teeth 6 on the surface of the grinding column 5 grind the top of the biological sample ice block, so that the top of the glacier sample ice block is ground into a hollow shape.

[0027] One end of the push rod 4 is fixedly connected with an extrusion block 22. The surface of the push rod 4 is movably sleeved with a spring 14. One end of the spring 14 is fixedly connected to the inner wall of the grinding column 5, and the other end of the spring 14 is fixedly connected to the surface of the push rod 4. The inner wall of the grinding column 5 is fixedly connected with a support column 23. The other end of the support column 23 is fixedly connected with a limit plate 20. The surface of the support column 23 is slidably connected with a sliding plate 18. The surface of the support column 23 is movably sleeved with a compression spring 19. One end of the compression spring 19 is fixedly connected to the inner wall of the grinding column 5, and the other end of the compression spring 19 is fixedly connected to the surface of the sliding plate 18. The surface of the grinding column 5 is provided with a sliding groove 21. The inside of the sliding plate 18 is fixedly connected with a sliding rod 17. The sliding rod 17 is inside the sliding groove 21. The surface of the sliding rod 17 is fixedly connected with a conical thorn 16, and the surface of the sliding rod 17 is slidably connected with the inside of the sliding groove 21.

[0028] When the grinding of the biological sample ice block is completed, press down the push rod 4, so that the extrusion block 22 on the surface of the push rod 4 moves downward, so that the upper part of the extrusion block 22 extrudes the sliding rod 17, so that the sliding rod 17 is extruded and slides inside the sliding groove 21, so that the conical thorn 16 is inserted into the ice block. The spring 14 is stretched and deformed by the downward pulling force. The sliding of the sliding rod 17 causes the sliding plate 18 to slide on the surface of the support column 23, so that the sliding plate 18 extrudes the compression spring 19 and deforms. The conical thorn 16 supports the ice block to prevent the ice block from sliding due to gravity. The sliding may cause the sample to break, deform or be damaged, affecting its integrity, and then interfering with the observation and analysis of the original characteristics and state of the sample. Re-collecting may face many difficulties, resulting in a serious delay in the progress of the entire research project, and improving the efficiency of sample collection.

[0029] When the ice collection device is placed in a suitable position, release the push rod 4 and no longer apply force to the push rod 4. The spring 14 is no longer subjected to the pulling force and returns to its original state, so that the push rod 4 slides upward inside the grinding column 5 and returns to its original state. Therefore, the compression spring 19 is no longer squeezed and returns to its original state, so that the sliding plate 18 slides on the surface of the support column 23 and returns to its original state, so that the sliding plate 18 drives the sliding rod 17 to slide inside the sliding groove 21 and returns to its original state. Therefore, the conical thorn 16 leaves the inside of the ice block and no longer supports the ice block.

[0030] The surface of the push rod 4 is fixedly connected with a rack 15. The rack 15 is L-shaped and is divided into upper and lower sections. The inner wall of the grinding column 5 is rotatably connected with a rotating shaft 24. The surface of the rotating shaft 24 is fixedly connected with a wire winding wheel 12. The inner wall of the grinding column 5 is fixedly connected with a support platform 9. The surface of the support platform 9 is fixedly connected with a fixing block 8. The surface of the fixing block 8 is movably sleeved with a return spring 7. One end of the return spring 7 is fixedly connected with the surface of the fixing block 8, and the other end of the return spring 7 is fixedly connected with a sliding block 25. The surface of the fixing block 8 is slidably connected with the inside of the sliding block 25. A rope 11 is wound around the surface of the wire winding wheel 12. The rope 11 is fixedly connected to the surface of the sliding block 25. The surface of the sliding block 25 is fixedly connected with a hammer 10.

[0031] Slide the push rod 4 upward inside the grinding column 5. The spring 14 is deformed by the extrusion of the grinding column 5, thereby causing the rack 15 to slide upward, thereby causing the rack 15 and the gear 13 to mesh, thereby driving the rotation of the rotating shaft 24, thereby causing the wire winding wheel 12 to rotate. Therefore, the rope 11 is retracted and wound around the surface of the wire winding wheel 12, thereby causing the rope 11 to pull the sliding block 25 to slide upward on the surface of the fixing block 8, thereby squeezing the return spring 7 to deform, thereby causing the hammer 10 to move upward. When the rack 15 moves to the middle position, the gear 13 is disengaged, thereby causing the gear 13 to stop rotating, thereby causing the rotating shaft 24 to stop rotating, thereby causing the sliding block 25 to stop sliding upward. Therefore, the extrusion of the return spring 7 stops, and the return spring 7 returns to its original state, thereby causing the sliding block 25 to slide instantaneously on the surface of the fixing block 8, thereby causing the hammer 10 to move downward instantaneously to strike the support platform 9. When the rack 15 moves to the lower half, the rack 15 and the gear 13 mesh and rotate, thereby driving the rotation of the rotating shaft 24, thereby causing the wire winding wheel 12 to rotate. Therefore, the rope 11 is retracted and wound around the surface of the wire winding wheel 12, thereby causing the rope 11 to pull the sliding block 25 to slide upward on the surface of the fixing block 8, thereby squeezing the return spring 7 to deform, thereby causing the hammer 10 to move upward. When the gear 13 is disengaged, the gear 13 stops rotating, thereby causing the rotating shaft 24 to stop rotating, thereby causing the sliding block 25 to stop sliding upward. Therefore, the extrusion of the return spring 7 stops, and the return spring 7 returns to its original state, thereby causing the sliding block 25 to slide instantaneously on the surface of the fixing block 8, thereby causing the hammer 10 to move downward instantaneously to strike the support platform 9.

[0032] When the push rod 4 is released, the push rod 4 is no longer subjected to force. Therefore, the grinding column 5 stops squeezing the spring 14, causing the spring 14 to return to its original state, which in turn drives the push rod 4 to slide downward inside the grinding column 5, causing the rack 15 and the gear 13 to mesh and rotate, driving the rotating shaft 24 to rotate, and then causing the winding wheel 12 to rotate. Thus, the rope 11 is retracted and wound around the surface of the winding wheel 12, pulling the sliding block 25 to slide upward on the surface of the fixed block 8, squeezing the return spring 7 to deform, and causing the hammer 10 to move upward. When the rack 15 moves to the middle position, the gear 13 disengages from the teeth, causing the gear 13 to stop rotating, the rotating shaft 24 to stop rotating, and the sliding block 25 to stop sliding upward. Therefore, the squeezing of the return spring 7 stops, and the return spring 7 returns to its original state, causing the sliding block 25 to slide instantaneously on the surface of the fixed block 8, and the hammer 10 to move downward instantaneously to strike the support platform 9. When the rack 15 moves to the lower half, the rack 15 and the gear 13 mesh and rotate, driving the rotating shaft 24 to rotate, and then causing the winding wheel 12 to rotate. Thus, the rope 11 is retracted and wound around the surface of the winding wheel 12, pulling the sliding block 25 to slide upward on the surface of the fixed block 8, squeezing the return spring 7 to deform, and causing the hammer 10 to move upward. When the gear 13 disengages from the teeth, the gear 13 stops rotating, the rotating shaft 24 to stop rotating, and the sliding block 25 to stop sliding upward. Therefore, the squeezing of the return spring 7 stops, and the return spring 7 returns to its original state, causing the sliding block 25 to slide instantaneously on the surface of the fixed block 8, and the hammer 10 to move downward instantaneously to strike the support platform 9. The shock waves generated by the hammer 10 striking the support platform 9 multiple times are transmitted to the inner wall of the entire grinding column 5, causing the inner wall of the grinding column 5 to vibrate, and the ice block to slide out of the inside of the drill bit 1 due to the vibration of being struck, preventing the biological sample from not falling due to the resistance of the ice block itself or the inner wall of the drill bit 1, and reducing the collection efficiency.

[0033] Working principle:

[0034] When collecting a glacier sample, the moving rod 2 slides on the surface of the screw rod 3, driving the screw rod 3 to rotate by the spiral shape. When the screw rod 3 rotates, it drives the drill bit 1 to rotate, so that the drill bit 1 drills the ice surface. When the screw rod 3 rotates, it can drive the grinding column 5 to rotate, and the grinding teeth 6 on the surface of the grinding column 5 grind the top of the biological sample ice block, making the top of the glacier sample ice block ground into a hollow shape.

[0035] After the grinding of the ice block of the biological sample is completed, press down the push rod 4, so that the extrusion block 22 on the surface of the push rod 4 moves downward, so that the upper part of the extrusion block 22 squeezes the sliding rod 17, so that the sliding rod 17 slides inside the sliding groove 21 under the extrusion, so that the cone spike 16 is inserted into the ice block, and the spring 14 expands and deforms under the downward pulling force, and the sliding rod 17 slides, so that the sliding plate 18 slides on the surface of the support column 23, so that the sliding plate 18 squeezes the compression spring 19 and deforms. The cone spike 16 supports the ice block to prevent the ice block from slipping under the action of gravity. The slipping may cause the sample to break, deform or be damaged, affecting its integrity, and then interfering with the observation and analysis of the original characteristics and state of the sample. Re-sampling may face many difficulties, resulting in a serious delay in the progress of the entire research project, and improving the efficiency of sample collection.

[0036] Slide the push rod 4 upward inside the grinding column 5. The spring 14 deforms under the extrusion of the grinding column 5, so that the rack 15 slides upward, so that the rack 15 meshes with the gear 13, so as to drive the rotating shaft 24 to rotate, so that the wire winding wheel 12 rotates. Therefore, the rope 11 is retracted and wound on the surface of the wire winding wheel 12, so that the rope 11 pulls the sliding block 25 to slide upward on the surface of the fixed block 8, so as to squeeze the return spring 7 and deform, so that the hammer 10 moves upward. When the rack 15 moves to the middle position, the gear 13 disengages from the teeth, so that the gear 13 stops rotating, so that the rotating shaft 24 stops rotating, so that the sliding block 25 no longer slides upward. Therefore, the squeezing of the return spring 7 stops, and the return spring 7 returns to its original state, so that the sliding block 25 slides instantaneously on the surface of the fixed block 8, so that the hammer 10 moves downward instantaneously to strike the support table 9. When the rack 15 moves to the lower half, the rack 15 meshes with the gear 13 and rotates, so as to drive the rotating shaft 24 to rotate, so that the wire winding wheel 12 rotates. Therefore, the rope 11 is retracted and wound on the surface of the wire winding wheel 12, so that the rope 11 pulls the sliding block 25 to slide upward on the surface of the fixed block 8, so as to squeeze the return spring 7 and deform, so that the hammer 10 moves upward. When the gear 13 disengages from the teeth, the gear 13 stops rotating, so that the rotating shaft 24 stops rotating, so that the sliding block 25 no longer slides upward. Therefore, the squeezing of the return spring 7 stops, and the return spring 7 returns to its original state, so that the sliding block 25 slides instantaneously on the surface of the fixed block 8, so that the hammer 10 moves downward instantaneously to strike the support table 9.

[0037] When the push rod 4 is released, the push rod 4 is no longer subjected to force. Therefore, the grinding column 5 stops squeezing the spring 14, causing the spring 14 to return to its original state, driving the push rod 4 to slide downward inside the grinding column 5, causing the rack 15 and the gear 13 to mesh and rotate, driving the rotating shaft 24 to rotate, driving the winding wheel 12 to rotate, causing the rope 11 to retract and wind around the surface of the winding wheel 12, causing the rope 11 to pull the sliding block 25 to slide upward on the surface of the fixed block 8, squeezing the return spring 7 to deform, causing the hammer 10 to move upward. When the rack 15 moves to the middle position, the gear 13 disengages, causing the gear 13 to stop rotating, causing the rotating shaft 24 to stop rotating, causing the sliding block 25 to stop sliding upward, stopping squeezing the return spring 7, and the return spring 7 returns to its original state, causing the sliding block 25 to slide instantaneously on the surface of the fixed block 8, causing the hammer 10 to move downward instantaneously to strike the support platform 9. When the rack 15 moves to the lower half, the rack 15 and the gear 13 mesh and rotate, driving the rotating shaft 24 to rotate, driving the winding wheel 12 to rotate, causing the rope 11 to retract and wind around the surface of the winding wheel 12, causing the rope 11 to pull the sliding block 25 to slide upward on the surface of the fixed block 8, squeezing the return spring 7 to deform, causing the hammer 10 to move upward. When the gear 13 disengages, the gear 13 stops rotating, causing the rotating shaft 24 to stop rotating, causing the sliding block 25 to stop sliding upward, stopping squeezing the return spring 7, and the return spring 7 returns to its original state, causing the sliding block 25 to slide instantaneously on the surface of the fixed block 8, causing the hammer 10 to move downward instantaneously to strike the support platform 9. The shock waves generated by the hammer 10 striking the support platform 9 are transmitted to the inner wall of the entire grinding column 5, causing the inner wall of the grinding column 5 to vibrate, causing the ice block to slide out of the inside of the drill bit 1 due to the vibration of being struck, preventing the biological sample from not falling due to the resistance of the ice block itself or the inner wall of the drill bit 1, and reducing the collection efficiency.
