Description

Technical Field

[0001] The invention relates to the field of water stoppers, and in particular to a pressure-sealed hole water stopper for geological drilling and a method thereof. Background Art

[0002] At present, in the process of geological drilling, the water stopper of the pressure-sealed hole is often only provided with one water stop. For example, application No. 202211704970.0 discloses a water stopper for a pressure-sealed hole for geological drilling, including a plug cover, a water stop plug and a pressure assembly. A fixing frame is arranged inside the plug cover, a water stop plug is clamped on the bottom side wall of the plug cover, an outlet pipe is welded on the bottom side wall of the water stop plug, and a pressure assembly is installed on the upper side wall of the water stop plug. The present invention adopts rubber material for the inner nesting and the anti-detachment rubber sleeve, which has high toughness and can ensure the sealing between them when contacting the drill bit. The height of the water-stop plug in the plug cover can be adjusted by the pressure component. When the water-stop plug and the plug cover are in an elongated state, the water outlet hole on the outer wall of the water-stop plug is exposed, and watering is performed so that water above the plug cover flows to the bottom. When the plug cover and the water-stop plug are in a contracted state, the water outlet hole is closed inside the plug cover, thereby forming a sealed and water-stopping effect.

[0003] However, the above-mentioned water stop and similar water stop only provide one water stop barrier when working. Once it fails, it will cause water leakage and lose the water stop effect. Therefore, improvement is needed. Summary of the invention

[0004] The object of the present invention is to provide a pressure-sealed hole water stopper for geological drilling and a method thereof to solve the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A pressure-sealed hole water stopper for geological drilling comprises a pressure-sealed hole, a threaded opening is fixedly arranged at the top of the pressure-sealed hole, a first sealing cover is threadedly connected to the top of the threaded opening, and a second sealing cover is threadedly connected to the top of the pressure-sealed hole.

[0007] Preferably, a base is fixedly provided on the top edge of the second sealing cover, the base is detachably connected to the connecting block, the connecting block is fixedly connected to the fixing seat, a socket is provided on the bottom of the fixing seat, a rod is slidably inserted in the socket, a piston is fixedly provided on the top of the rod, the piston is slidably connected to the inner wall of the socket, and a floating block is fixedly provided on the lower end of the rod.

[0008] Preferably, a controller is fixedly provided at the top of the socket, a self-reset control button is provided at the bottom of the controller, the top of the socket is fixedly connected to the lower ends of a plurality of second springs, and the upper ends of the second springs are fixedly connected to the top of the socket.

[0009] Preferably, the controller is wirelessly connected to the small motor, the small motor is fixedly connected to the top of the second sealing cover, a waterproof box is provided on the outside of the small motor, the waterproof box is fixedly connected to the second sealing cover, the power output end of the small motor is fixedly connected to both ends of the rope, the rope is wrapped around the first sealing cover, and a limiting ring is provided on the fixed sleeve of the first sealing cover, and the limiting ring is located above the rope.

[0010] Preferably, a water storage pan is sleeved on the pressure sealing hole, and the water storage pan is fixedly connected to the pressure sealing hole. A cover plate is provided on the water storage pan, and a slide cylinder is fixedly penetrated through the center of the cover plate, and the slide cylinder is slidably sleeved on the pressure sealing hole, and a plurality of water storage pipes are penetrated through the side of the cover plate close to the pressure sealing hole, and the water storage pipes are fixedly connected to the cover plate.

[0011] Preferably, a side of the cover plate close to the pressure sealing hole is recessed inwardly.

[0012] The beneficial effects of the present invention are:

[0013] 1. The present invention provides protection by installing a first sealing cover and a second sealing cover on the pressure sealing hole, thereby effectively preventing water sample leakage in the pressure sealing hole. By setting two water-stopping barriers, water leakage can be effectively prevented.

[0014] 2. When the second sealing cover is installed, the fixing seat is pressed against the first sealing cover. As the second sealing cover rotates, the fixing seat rotates synchronously and drives the first sealing cover to rotate under the action of friction, so that the first sealing cover can be further tightened to prevent water leakage from the pressure sealing hole.

[0015] 3. When the first sealing cover is not sealed tightly and water leaks out, water accumulates in the second sealing cover. When the water accumulation in the second sealing cover reaches a certain level, the small motor starts to drive the rope to spirally wind, so that the rope wrapped around the first sealing cover is tightened to tighten the first sealing cover and prevent the water in the pressure sealing hole from continuing to leak out.
