Description

Technical Field

[0001] This utility model relates to the field of ice thickness measurement technology, specifically to an ice thickness measurement device. Background Technology

[0002] Ice thickness measurement is of great significance in many fields, such as meteorological research, water conservancy projects, transportation, and polar scientific expeditions. The common method is to manually use a drill rod to cut into the ice layer by rotating it until it penetrates the ice layer to the bottom. Then, the measuring tool is inserted into the ice layer to obtain the thickness value.

[0003] Typically, the ice layer to be measured is quite thick. If a drill rod is used to penetrate the ice layer directly, it will encounter significant resistance, making the operation quite laborious. Furthermore, it is difficult for a person to maintain a vertical position while using a drill rod to penetrate the ice layer, which can easily lead to deviation. This can result in the subsequent measuring tools being misaligned, affecting the measurement results.

[0004] In order to reduce the difficulty of ice penetration work before measurement and reduce the impact on measurement results, this application proposes an ice thickness measuring device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an ice thickness measuring device that delivers heat flow to the location where the ice layer is to be penetrated, thereby melting the ice surface and reducing the ice layer's hardness.

[0007] Further description: A bellows is fixedly connected to the bottom end of the sleeve, and a pressure ring is fixedly connected to the bottom end of the bellows. A counterweight groove is provided on all four sides of the top of the pressure ring. Here, the bellows is in a folded state, and it will only be stretched when conveying heat.

[0008] Further description: A retaining frame is fixedly connected to the inner wall of the left side at both ends of the air collection box. A motor is fixedly connected to the left end of the retaining frame. The drive end of the motor passes through the right side of the retaining frame and is fixedly connected to an impeller. Here, the motor serves as a power source to provide rotational power to the impeller. During the rotation of the impeller, outside air is drawn in from multiple slots at one end of the air collection box and then blown to the other side.

[0009] Further description: Pulling blocks are provided on the inner walls of both the upper and lower sides of the left end of the scale, and traction rods are fixedly connected to the right ends of the pulling blocks. The outer walls of the traction rods are slidably connected to the inner walls of the scale, and a connecting rod is fixedly connected to the right side of one end of the traction rod. Here, the connecting rod acts as a linkage component, and when one traction rod moves, it will inevitably drive the other traction rod to move.

[0010] Further description: The inner wall of the horizontal plate is slidably connected to the front side of the rotating shaft with a rod. The shape of the top of the rod matches the shape of the inner wall of the limiting hole. A pressure plate is fixedly connected to the upper side of the front end of the rod. Here, the top of the rod is circular, and its outer diameter is the same as the inner diameter of the limiting hole.

[0011] Further description: A spring is fixedly connected to the bottom end of the pressure plate, and the bottom end of the spring is fixedly connected to the top end of the horizontal plate; here, the spring will generate elastic potential energy after being pressed down by the pressure plate.

[0012] Further description: Each of the four corners of the outer wall of the frame is fixedly connected to a bracket, and each bracket is fixedly connected to a base plate; here, the brackets are set so that the frame is kept at a certain distance from the ice surface.

[0013] Further description: Heating rods are fixedly connected to the outer side of the inner wall of the base plate and penetrate the bottom of the base plate. A protective shell is fixedly connected to the bottom end of the base plate outside the heating rods. Here, the heating rods are existing technology components that can generate heat and are waterproof. The protective shell is made of metal, which has excellent thermal conductivity and protects the heating rods from damage.

[0014] Beneficial effects:

[0015] 1. In this utility model, through the cooperation of a motor, a mounting frame, an impeller, an electric heating wire, an air supply pipe, a sleeve, a corrugated pipe, and a pressure ring, heat flow is delivered to the location where the ice layer needs to be penetrated, causing the ice surface to melt and reducing the hardness of the ice layer. Furthermore, while drilling through the ice layer, the heat flow is continuously delivered, thereby melting the ice debris in the ice into water. The melted ice water can reduce the friction between the bottom of the drill rod and the ice layer, reduce the wear of the bottom of the drill rod and the resistance during drilling, making it easier to penetrate the ice layer.

[0016] 2. In this utility model, the electric heating rod is connected to the power supply to heat its surface. Then, through the conduction of the metal material of the protective shell, the heat is transferred to the contact ice surface, causing the contact part to gradually melt into a pit. The protective shell is then trapped in the pit, keeping the bottom plate in a limited position. This improves the overall stability of the device during the ice drilling process. Furthermore, the connection of the horizontal plate, rotating shaft, and connecting plate limits the position of the drill rod, ensuring that the drill rod remains vertical during the ice drilling process and preventing deviation when penetrating the ice layer, which would affect the subsequent measurement results.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4 , Figure 6 An ice thickness measuring device includes a frame 1. A horizontal plate 6 is fixedly connected to the inner wall of the lower middle section of both ends of the frame 1. A rotating shaft 10 is rotatably connected to the middle of the top of the horizontal plate 6. A connecting plate 7 is fixedly connected to the top of the rotating shaft 10. Limiting holes 20 are formed on the middle of both the front and rear sides of the bottom end of the connecting plate 7. A damping sleeve 21 is fixedly connected to the left side of the inner wall of the connecting plate 7. A scale 8 is slidably connected to the inner wall of the damping sleeve 21. A damping sleeve 19 is slidably connected to the outer wall of the scale 8 located below the connecting plate 7. A drill rod 9 is threadedly connected to the right side of the inner wall of the connecting plate 7. A sleeve 15 is fixedly connected to the bottom end of the connecting plate 7 located outside the drill rod 9. An air collecting box 14 is fixedly connected to the bottom end of the horizontal plate 6 located to the left of the sleeve 15. An electric heating wire 25 is installed on the lower right side of the inner wall of the air collecting box 14. A mounting bracket 26 is fixedly connected to the inner wall of the left side of both ends of the air collection box 14. A motor 23 is fixedly connected to the left end of the mounting bracket 26. The drive end of the motor 23 passes through the right side of the mounting bracket 26 and is fixedly connected to an impeller 24. An air supply pipe 16 is fixedly connected to the lower right side of the air collection box 14. The right end of the air supply pipe 16 is fixedly connected to the left end of the sleeve 15. A corrugated pipe 17 is fixedly connected to the bottom end of the sleeve 15. A pressure ring 18 is fixedly connected to the bottom end of the corrugated pipe 17. A counterweight groove 22 is opened on all four sides of the top of the pressure ring 18. A bracket 2 is fixedly connected to the four corners of the outer wall of the frame 1. A base plate 3 is fixedly connected to the bottom end of the bracket 2. An electric heating rod 4 is fixedly connected to the outer side of the inner wall of the base plate 3 and passes through the bottom of the base plate 3. A protective shell 5 is fixedly connected to the bottom end of the base plate 3 outside the electric heating rod 4.

[0027] To explain further, firstly, the entire frame 1 is moved onto the ice surface, and the bottom of the protective shell 5 is brought into contact with the ice surface. Then, the power supply to the heating rod 4 is turned on. After the surface of the heating rod 4 heats up, the heat will be conducted to the ice surface through the metal material of the protective shell 5 itself. Under the action of heat, the ice surface gradually melts until a pit is formed. Then, the power supply is turned off, and the protective shell 5 is stuck in the pit. This can limit the position of the base plate 3, improve the stability of the entire device during the ice drilling process, and prevent the bottom of the base plate 3 from slipping on the ice surface.

[0028] Next, lower the pressure ring 18 so that its bottom fits tightly against the ice surface. At the same time, the corrugated pipe 17 will extend and expand to form a longer pipe shape, which will shield the subsequent heat flow and reduce heat loss. It can also limit the direction and range of the heat flow. The accessory box at the top of the horizontal plate 6 contains counterweights. These counterweights are inserted into the counterweight groove 22 at the top of the pressure ring 18 in sequence. By adding counterweights, the gravity on the pressure ring 18 is increased, so that its bottom can fit more firmly against the ice surface. Then, press the switch at the front of the air collection box 14 to turn on the power to the heating wire 25 and the motor 23. The heating wire 25 starts to heat up. The drive end of the motor 23 drives the impeller 24 to rotate and generate airflow, which is blown towards one side of the heating wire 25. After the airflow passes through the heated heating wire 25, the temperature rises and heat flow is formed. The heat flow is discharged into the sleeve 15 along the air supply pipe 16 and then blown along the corrugated pipe 17 to the corresponding part of the ice surface.

[0029] The heat flow continues to act on the ice surface, causing it to gradually melt and the ice layer to become less hard. At this point, by holding the handle at the top of drill rod 9 and turning it, the bottom of drill rod 9 can drill into the ice surface. Due to the reduced hardness of the ice layer, the drilling process is relatively easy. As drill rod 9 drills into the ice layer, the heat flow continues to be delivered, which not only melts the drilled ice fragments into water and allows them to flow into the ice layer, but also uses the lubricating effect of water to reduce the friction between the bottom of drill rod 9 and the ice layer. As a result, the wear at the bottom of drill rod 9 is reduced, the resistance when drilling ice is significantly reduced, and the work of penetrating the ice layer becomes easier.

[0030] Example 2

[0031] Please see Figure 5 Further, based on Embodiment 1, the inner wall of the horizontal plate 6 is slidably connected to the front side of the rotating shaft 10 with a rod 11. The shape of the top end of the rod 11 matches the shape of the inner wall of the limiting hole 20. A pressure plate 12 is fixedly connected to the upper side of the front end of the rod 11. A spring 13 is fixedly connected to the bottom end of the pressure plate 12. The bottom end of the spring 13 is fixedly connected to the top end of the horizontal plate 6. Pulling blocks 28 are provided on the upper and lower inner walls of the left end of the scale 8. A traction rod 29 is fixedly connected to the right end of the pulling block 28. The outer wall of the traction rod 29 is slidably connected to the inner wall of the scale 8. A connecting rod 27 is fixedly connected to the right side of the opposite end of the traction rod 29.

[0032] To further explain, after completing the work of penetrating the ice layer, the power supply to the motor 23 and the heating wire 25 is disconnected in time. Then, the bellows 17 and drill rod 9 are retracted. Then, the pressure plate 12 is pressed, and the bottom of the pressure plate 12 squeezes the spring 13. The insertion rod 11 slides down and its top disengages from the front limiting hole 20, releasing the limitation on the connecting plate 7. The connecting plate 7 is rotated so that the scale 8 is above the penetrating ice layer. Then the pressure plate 12 is released. Under the elastic force of the spring 13, the pressure plate 12 drives the insertion rod 11 to reset and insert it into the limiting hole 20 that was originally located on the rear side, thereby limiting the connecting plate 7 again.

[0033] Finally, push the scale 8 downwards so that its outer wall slides inside the damping sleeve 21. The damping sleeve 19 will also move accordingly. When the damping sleeve 19 moves to the penetration point of the ice layer, its bottom will be blocked by the ice surface because its length at both ends is greater than the outer diameter of the drill rod 9. The scale 8 continues to go deeper. When the top is close to the damping sleeve 21, pull the upper pull block 28 outwards. With the cooperation of the traction rod 29 and the connecting rod 27, the lower pull block 28 extends outwards. Then lift the scale 8 until the top of the lower pull block 28 is blocked by the bottom of the ice layer. Then slide the damping sleeve 19 downwards so that its bottom is in contact with the top of the ice layer. At this time, the scale position corresponding to the bottom of the damping sleeve 19 and the surface of the scale 8 is the real-time thickness of the ice layer. The measurement of the ice thickness is now complete.

[0034] Additional notes: When using the device in practice, it is necessary to set up the relevant power supply and wiring, which are not directly shown in the figure.

[0035] Working principle: First, the frame 1 is moved onto the ice surface. Then, the bottom of the protective shell 5 is brought into contact with the ice surface. The electric heating rod 4 is connected to the power supply to heat its surface. Through the conduction of the metal material of the protective shell 5, the heat is transferred to the ice surface, causing it to gradually melt until a pit is formed. Then, the power supply is disconnected. At this time, the protective shell 5 is stuck in the pit, maintaining the limiting effect on the base plate 3, thereby improving the stability of the device as a whole during the ice drilling process and preventing the bottom of the base plate 3 from slipping on the ice surface.

[0036] Next, pull down the pressure ring 18 so that its bottom is in contact with the ice surface. At the same time, the corrugated pipe 17 extends and forms a long pipe. The accessory box is fixed at the top of the horizontal plate 6. The counterweights in the box are then inserted into the counterweight groove 22 at the top of the pressure ring 18 to increase the gravity on the pressure ring 18 and keep its bottom in close contact with the ice surface. Then, press the switch at the front of the air collection box 14 to connect the heating wire 25 and the motor 23 to the power supply. The heating wire 25 starts to heat up. The motor 23 drives the impeller 24 to rotate and blows airflow to one side of the heating wire 25. The airflow forms a hot flow after passing through the heating wire 25 and is discharged into the sleeve 15 along the air supply pipe 16, and then blown into the ice surface at that location along the corrugated pipe 17.

[0037] A continuous flow of heat is blown into the ice surface, causing it to gradually melt and reduce its hardness. Then, the handle at the top of drill rod 9 is held and rotated, allowing the bottom of drill rod 9 to drill into the ice surface. The ice surface with reduced hardness is relatively easy to drill into. As drill rod 9 drills into the ice surface, a continuous flow of heat is delivered, which melts the drilled ice fragments into water, which flows into the ice surface. Furthermore, the friction between the bottom of drill rod 9 and the ice surface is reduced due to the lubrication of the water, reducing wear on the bottom of drill rod 9 and reducing resistance when drilling ice, making the work of penetrating the ice surface easier.

[0038] After completing the work of penetrating the ice layer, disconnect the power supply of motor 23 and heating wire 25, then retract the bellows 17 and drill rod 9, then press the pressure plate 12, the bottom of which squeezes the spring 13, causing the insertion rod 11 to slide down and its top to disengage from the front limiting hole 20, thus releasing the limitation on the connecting plate 7. Then rotate the connecting plate 7 so that the scale 8 is above the penetrating ice layer, then release the pressure plate 12. Under the elastic force of the spring 13, the pressure plate 12 drives the insertion rod 11 to reset and insert it into the original rear limiting hole 20, thus limiting the connecting plate 7.

[0039] Then, the scale 8 is pushed downwards, causing its outer wall to slide within the damping sleeve 21. The damping sleeve 19 moves accordingly. When the damping sleeve 19 moves to the point where the ice penetrates, its bottom will be blocked by the ice because the length of both ends of the damping sleeve 19 is greater than the outer diameter of the drill rod 9. The scale 8 continues to penetrate deeper. When the top of the scale 8 is pushed close to the damping sleeve 21, the upper pull block 28 is pulled outwards. With the cooperation of the traction rod 29 and the connecting rod 27, the lower pull block 28 extends outwards. Then, the scale 8 is lifted until the top of the lower pull block 28 is blocked by the bottom of the ice. Then, the damping sleeve 19 is slid downwards, so that its bottom is in contact with the top of the ice. At this time, the scale position where the bottom of the damping sleeve 19 aligns with the surface of the scale 8 is the real-time thickness of the ice. This completes the measurement of the ice thickness.
