Description
Technical Field
The utility model relates to a water drainer in a hole; the device is suitable for draining accumulated water in the drill hole which is arranged vertically downwards or obliquely downwards.
Background
In water conservancy and hydropower or mining engineering, it is often necessary to drill holes in rock for various reasons, such as exploration, grouting and shoring. After some drilling holes are finished, water is often accumulated in the holes, and subsequent work can be carried out after water is drained, for example, television test in the holes, sealing of an orifice section by cement slurry before grouting and the like. The diameter of a drilling hole for television test and grouting in the hole is about 42-120 mm, the hole diameter is small, the water amount in the hole is not large, and if equipment such as a drainage pump is adopted, the equipment is usually large and small in size, and power supply equipment is required to be configured.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: aiming at the existing problems, the in-hole drainer has the advantages of simple structure, convenient manufacture and lower cost.
The utility model adopts the technical proposal that: the utility model provides an downthehole drainer for get rid of ponding in the drilling, its characterized in that: the tubular water storage mechanism is provided with a tubular water storage mechanism, the shape and the size of the tubular water storage mechanism are matched with those of the drilled holes, a water storage chamber is arranged in the tubular water storage mechanism, a hole for communicating the outside with the water storage chamber is formed in the lower end of the tubular water storage mechanism, and a one-way valve is arranged in the hole.
The tubular water storage mechanism is provided with a water storage pipeline and an end sleeve connected to the lower end of the water storage pipeline, and the one-way valve is installed in the end sleeve.
The check valve is provided with a metal sheet with the shape and the size matched with the hole, a rubber sheet with the shape matched with the metal sheet and the size slightly larger than the metal is concentrically fixed below the metal sheet, and the edge of the rubber sheet is provided with a connecting block and is fixed on the edge of the hole through the connecting block.
The metal sheet and the rubber sheet are fixed through bolts penetrating through the metal sheet and the rubber sheet.
The end sleeve is connected with the water storage pipeline through a screw thread.
The rubber sheet is fixed on the edge of the hole through a bolt.
The upper end of the tubular water storage mechanism is connected with a rope.
The utility model has the advantages that: after the drainer is inserted into the drill hole, the one-way valve at the lower end of the tubular water storage mechanism is opened inwards under the action of water pressure in the hole, and accumulated water in the hole enters the water storage cavity in the tubular water storage mechanism; when the drainer is pulled out of the hole, the one-way valve is closed under the action of the gravity of the water in the water storage cavity, so that the accumulated water in the hole is reserved outside the hole in the water storage cavity. The utility model discloses simple structure, convenient operation, do not power consumptive, do not need the lead wire or be equipped with power supply facility.

Detailed Description
The embodiment is a downthehole drainer for getting rid of ponding in the drilling, including tubulose water storage mechanism, have the water storage cavity in the tubulose water storage mechanism, this tubulose water storage mechanism comprises water storage pipeline and the end sleeve pipe that connects in the water storage pipeline lower extreme, and wherein tip sleeve pipe end welding or threaded connection a slice support ring to form the hole at end sleeve pipe lower extreme, correspond the hole and install the check valve.
In the embodiment, the water storage pipeline can adopt a metal pipe or a plastic pipe, and the length of the water storage pipeline is determined according to the actual operable space and the hole depth; the end sleeve is preferably a metal tube, and the length of the end sleeve is preferably less than 10cm, so that the one-way valve is convenient to disassemble and replace. The end sleeve is reliably connected with the water storage pipeline through the screw thread, and the end sleeve is ensured not to fall off under the action of water load.
In this embodiment, the check valve is installed above the hole in the end sleeve, the check valve has a metal sheet and a rubber sheet fixed below the metal sheet, the metal sheet is circular and has a diameter matched with the hole, the rubber sheet is circular and has a diameter slightly larger than the hole, and the rubber sheet and the metal sheet are fixed by a bolt penetrating through the centers of the two circles. The rubber sheet is used for sealing water and the metal sheet is used for bearing the water load in the water outlet pipe. In this case, the rubber sheet has a connecting piece at its edge, and the check valve is fixed to the upper end of the support ring around the hole by bolts via the connecting piece.
When the drilling depth is deeper, the top of the water storage pipeline of the drainer can be drilled and connected by a rope, so that the drainable range of the drainer is extended.
The working principle of the embodiment is as follows: after one end of the in-hole drainer with the one-way valve is inserted into the hole, the one-way valve is opened inwards under the action of water pressure in the hole, and accumulated water in the hole enters the water storage chamber; when the drainer is pulled out of the hole, the one-way valve is closed under the action of gravity of water in the water storage cavity, so that accumulated water in the hole is reserved in the water storage pipeline and is taken out of the hole.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
