Embodiment 1

[0026] Embodiment 1, the present invention is a groundwater level detection device for hydrogeological exploration, comprising a support base 1 placed on the ground, and a pre-drilled measuring hole 2 on the ground. The detector goes deep into the measuring hole 2, and measures the water level in the measuring hole 2. The upper end of the supporting base 1 is fixedly connected with a fixed horizontal plate 3, and the fixed horizontal plate 3 provides the follow-up structure. The fixed support foundation, the middle position of the fixed horizontal plate 3 is fixedly connected with a limit ring sleeve 4, and the limit ring sleeve 4 is fixedly connected with a number of sliding boxes 5, and the sliding boxes 5 are all along the The limit ring sleeve 4 is radially slidably connected with a sliding limit sleeve 6, and the sliding limit sleeve 6 is rotatably connected with a limit ball 7, and the limit ball 7 is in the sliding limit sleeve 6. Free rotation inside, the sliding limit...

Embodiment 2

[0027] Embodiment 2, on the basis of Embodiment 1, in the process of supporting the inner wall of the measuring hole 2 through the measuring cylinder 9, during the disassembling process of the measuring cylinder 9, due to the influence of the geological environment, It may cause damage to the upper end of the measurement hole 2, especially the upper port, or even collapse. Therefore, this embodiment provides a combined measurement cylinder 9 to avoid damage to the inner wall of the measurement hole 2. Specifically, the measuring cylinder 9 includes two half-arc cylinders 15 and two limit arc plates 16 . Both sides of the two half-arc cylinders 15 are provided with arc-shaped limit rails 17 . The arc-shaped limiting bars 18 are fixedly connected to the arc-shaped limiting rails 17. The half-arc cylinder 15 and the limiting arc-plate 16 are closed to form a cylinder. The cooperation of the half arc cylinder 15 and the limit arc plate 16 realizes the combination of the measuring ...

Embodiment 3

[0028] Embodiment 3, on the basis of Embodiment 1, when the holding force of the spring 8 and the limiting ball 7 on the measuring cylinder 9 is too large, it is difficult to realize the measurement cylinder 9 through external pulling. The retraction and release of 9 is time-consuming and laborious. When the holding force is too small, it cannot achieve a good fixing effect in the up and down direction. Therefore, this embodiment provides a method for measuring the measuring cylinder 9 under the action of a large holding force. The structure for retracting and placing, specifically, the lower end of the limit ring sleeve 4 is fixedly connected with a fixed sleeve 19, and the front and rear sides of the fixed sleeve 19 are rotatably connected with conveying rollers 20. The idler 20 is in the shape of a dumbbell, and the middle arc surface of the conveying idler 20 is in contact with the outer wall of the measuring cylinder 9. Through the reverse rotation of the two conveying idl...

Abstract

The invention provides an underground water level detection device for hydrogeological exploration. The problems that in the underground water level detection process, a detector cannot be adjusted in real time along with the water level position, a well wall cannot be supported, the well wall collapses, and a well wall supporting cylinder is controlled to be folded and unfolded are solved. The device comprises a supporting base arranged on the ground and a measuring hole, the upper end of the supporting base is fixedly connected with a fixed transverse plate, the middle position of the fixed transverse plate is fixedly connected with a limiting circular ring sleeve, the limiting circular ring sleeve is fixedly connected with a plurality of sliding boxes, and sliding limiting sleeves are slidably connected in the sliding boxes in the radial direction of the limiting circular ring sleeve; a limiting ball is rotatably connected in the sliding limiting sleeve, the sliding limiting sleeve is connected with the sliding box through a spring, a plurality of measuring cylinders are coaxially arranged in the measuring hole and are connected end to end up and down, the lower end of the measuring cylinder at the lowest end is fixedly connected with a conical positioner through a bolt, and the measuring cylinder at the upper end is arranged in a limiting circular ring sleeve; the device is exquisite in structure and has very high practicability.

Description

technical field [0001] The invention relates to the technical field of water level detection, in particular to a groundwater level detection device for hydrogeological exploration. Background technique [0002] Hydrogeology, a branch of geology, refers to the phenomena of various changes and movements of groundwater in nature. Hydrogeology is the science of groundwater. It mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational use, the adverse effects of groundwater on engineering construction and mining and its prevention and control. With the development of science and the needs of production and construction, hydrogeology is divided into regional hydrogeology, groundwater dynamics, hydrogeochemistry, water supply hydrogeology, mineral deposit hydrogeology, soil improvement hydrogeology and other branches. [0003] At present, the observation of groundwater le...
