The invention relates to a portable cast-in-place pile hole bottom sediment thickness detection device. The detection device comprises a transportation plate trailer and a thickness detection assembly, a winding mechanism is arranged on the transportation plate trailer, one end of the winding mechanism is fixedly connected with the thickness detection assembly, and the thickness detection assembly comprises a bearing mechanism, a leveling mechanism, a detection mechanism and a moving mechanism; the bearing mechanism serves as a supporting mechanism of the whole detection assembly, the leveling mechanism adjusts the levelness of the detection mechanism and the bearing mechanism, the detection mechanism is used for detecting the sediment thickness, and the moving mechanism is used for driving the whole detection assembly to move. The overall flexible movement of the device is realized through the transportation plate trailer, the winding mechanism can stably lower the detection assembly into a cast-in-place pile hole, the detection assembly can be leveled in the hole through the leveling mechanism, the detection assembly is convenient to move through the moving mechanism, the heavy detection assembly does not need to be manually carried or dragged, and the detection efficiency is improved. The problems that existing equipment is large in size, and manual position adjustment is inconvenient are solved.

The invention relates to the technical field of temperature measurement, and discloses a temperature measuring device for a geothermal well, which comprises a cylindrical measuring main body, a plurality of side blocks are arranged on the side wall of the measuring main body at equal intervals in the circumferential direction, grooves are formed in the side blocks, shaft pieces are rotationally connected in the grooves, and first torsion springs are arranged between the shaft pieces and the grooves; a swing arm is obliquely arranged on the shaft piece, an end groove is formed in the end, away from the shaft piece, of the swing arm, a supporting shaft is rotationally connected into the end groove, and the supporting shaft is sleeved with a roller. A temperature detector is arranged in the end groove and located in the projection range of the rolling wheel. The geothermal well temperature measuring device mainly solves the problem that operation is tedious when an existing geothermal well temperature measuring device enters a geothermal well.

This utility model relates to a tool for measuring the furnace lining of an aluminum electrolytic cell, belonging to the field of electrolytic cell measurement technology. It includes a handheld part with scale lines, a tank insertion part at the end of the handheld part, and a movable scale sleeved on the handheld part and movable along the handheld part in both the lateral and longitudinal directions. When it is necessary to measure the furnace lining thickness at different locations in the aluminum electrolytic cell, it is only necessary to move the handheld part along the longitudinal direction of the movable scale to achieve multi-point measurement of the furnace lining in the aluminum electrolytic cell.
