Problems solved by technology

First, it is difficult to observe the intersection position of the planes under the ice layer, and the error is relatively large; second, drilling holes on the ice surface cannot be measured twice, and the ice holes will be sealed, and they must be drilled again to measure

Embodiment 1

[0038] Such as figure 1 Shown, a kind of ice layer thickness measuring device comprises hollow tube 1, fire-fighting waterproof hose 2, T-shaped angle iron 3, hollow tube 4, rope 5, clamp 6 and counterweight 7;

[0039] Such as figure 2 As shown, the shape of the hollow tube 1 is a cylindrical tube with an open upper end, and an opening 11 is opened in the center of the bottom surface;

[0040] One end of the waterproof hose 2 is sealed, and one end has a mouth, and the T-shaped angle iron 3 is loaded from the mouth of the waterproof hose 2, and a section of the waterproof hose 2 with a mouth is passed through the opening 11;

[0041] Such as image 3 As shown, the T-shaped angle iron 3 is composed of a rectangular iron plate 31 and a circular iron block 32. One end of the iron plate 31 is connected and fixed with the center of the iron block 32. On the other side of the iron plate 31, there is a hole near the end position. The through hole 33; the diameter of the iron blo...

Embodiment 2

[0063] This embodiment only describes the differences from Embodiment 1;

[0064] Such as Figure 5 As shown, the edge of the upper surface of the circular iron block 32 of the T-shaped angle iron 3 is provided with several protrusions 34 for limiting the movement of the waterproof hose 2 and reducing measurement errors.

Abstract

The invention discloses an ice layer thickness measuring device and method. The device comprises a hollow cylinder, a water-proof flexible pipe for fire protection, a T-shaped angle iron, a hollow pipe and a rope; a hole is formed in the bottom face of the hollow cylinder, one end opening of the water-proof flexible pipe is sealed, the other end opening is reserved, the T-shaped angle iron is firstly put in the water-proof flexible pipe, the flexible pipe penetrates through the opening formed in the bottom face of the hollow cylinder, the hollow pipe is put in the water-proof flexible pipe, one end of the rope is connected with the T-shaped angle iron, and the other end penetrates through the hollow pipe. The method comprises the steps that a hole is made in the ice, and the device is putin the hole; the rope is pulled upwards until the top of the hollow cylinder is in contact with the bottom of the ice layer; the ice layer thickness is calculated. The device and method have the advantages that long-term monitoring for the ice layer thickness of a lake at a fixed point is carried out under the guarding circumstance, making a hole each time for observation is not needed, manpower and time are saved, and the measurement is accurate.

Description

technical field [0001] The invention relates to the technical field of ice layer thickness measurement, in particular to an ice layer thickness measurement device and method. Background technique [0002] In northern my country and plateau areas, the winter is long and cold, and water bodies such as rivers, lakes, and reservoirs are frozen for a long period of time. In the field of ecological investigation and research in water areas and in the management of overwintering and winter fishing in large-scale fisheries, it is necessary to carry out when the ice layer in frozen waters reaches a certain safe thickness. Collect water, biological samples and other operations. [0003] Currently, measurements require drilling holes in the ice and measuring with a ruler. This method of measurement requires drilling holes in the ice and then measuring with a ruler. First, it is difficult to observe the intersection position of the planes under the ice layer, and the error is relativel...
