[0002] Water exploration drilling is a detection measure taken to understand the hydrological situation and accurately grasp the location, scope and water volume of water bodies or water-bearing structures. Water exploration drilling is an important technical means in geological exploration. Through scientific drilling methods and safety technical measures, groundwater resources can be effectively detected, providing reliable geological and hydrological information for the development of water resources and the construction of engineering projects.

[0003] After searching, the publication number: CN210049857U discloses a rapid sealing device for water exploration drilling holes in coal mines. In the utility model, the device is inserted into the hole, and the slider is pushed to slide to the left under the elastic force of the spring. The middle support rod is unfolded under the action of the crank slider mechanism. At the same time, the middle support rod unfolds the left support rod under the action of the double crank mechanism. At the same time, the water retaining cloth is unfolded to block the hole. The end of the support rod contacts and supports the hole wall. Under the action of the elastic force of the spring and the pressure of water, the device is supported in the hole. The gap between the two groups of water retaining cloths is filled with sealing filling glue through the glue outlet hole to fully seal the hole. However, in the sealing process, the existing sealing method often has the problem of sealant dispersion due to the action of water flow, which affects the sealing work and the sealing effect is not good.

When the device is in use, the connecting hole flat plate can be inserted into the inner wall of the water exploration drilling hole. During this process, the fixed bracket is always embedded in the blind hole and does not extend out of the connecting hole flat plate. Since the internal compression spring is always in a compressed state, under the elastic support of the spring, the top periphery of the fixed bracket is placed above the drilling hole, so that the connecting hole flat plate cooperates with the fixed bracket to form a stable clamping effect of the device, and finally screwed into the threaded hole with bolts and connected to the coal mine ground, thereby improving the overall stability performance.

[0006] During sealing, the two sets of connecting flange plates are fitted along the periphery of the seamless steel casing, and the multi-layer sealing rubber rings are sleeved on the relative inner sides of the two sets of connecting flange plates and are squeezed, thereby enhancing the sealing effect and preventing the problem of the sealing glue flowing away; on the other hand, the surface of the mounting block at the upper end of the sealing top cap is closely fitted with the L-shaped clamping block. To prevent the device from shaking caused by underground ventilation, since the compression spring II inside is always in a compressed state, through the cooperation of the telescopic rod and the L-shaped clamping block, the mounting block and the connecting hole flat plate connected to the bottom are given a certain stable lifting effect, preventing air leakage during ventilation.

On this basis, a high-efficiency sealing mechanism 1 is added.
