Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to hydrogeological survey, in particular to a field drilling circulation fluid rapid pumping device. Background Art
[0002] In hydrogeological surveys, it is necessary to extract water from geological boreholes to obtain hydrogeological parameters. However, hydrogeological boreholes are generally constructed in areas with broken rock structures such as faults and folds. Therefore, during the pumping experiment, the boreholes often collapse and groundwater brings in a lot of rock particles.
[0003] In traditional water pumping experiments, buckets are still widely used in areas with large water level burial depth, small water volume, and low test requirements. It can reduce the economic losses caused by hole collapse during the water pumping process and is a non-continuous water pumping tool. However, when pumping water, the efficiency of bucket pumping is inversely proportional to the depth of the borehole. The deeper the borehole, the lower the efficiency of water pumping. Utility Model Content
[0004] The utility model aims to provide a field drilling circulation fluid fast pumping device, which can solve the problem of low pumping efficiency of traditional bucket pumping devices.
[0005] To this end, the technical solution adopted by the utility model is: a field drilling circulating fluid rapid pumping device, including a lifting bucket, a cylindrical measuring column is arranged in the lifting bucket, rubber sheets are symmetrically arranged on the left and right sides of the bottom of the lifting bucket, the opposite ends of the two rubber sheets are fixedly connected to the inner side of the lower wall of the lifting bucket by screws, the lifting bucket is left with an opening at a corresponding position below the rubber sheet, the size of the rubber sheet is larger than the size of the opening, the upper end of the measuring column is connected to the drilling rig, and the lifting bucket is driven by the drilling rig to move up and down in the borehole to complete pumping.
[0006] Preferably, the upper outer surface of the measuring column is threaded to connect with the drilling rig. The upper outer surface of the measuring column is threaded to facilitate connection with the drilling rig, and the rotation of the drilling rig drives the measuring column and the bucket to rise or fall quickly, thereby improving the pumping efficiency.
[0007] More preferably, the lower end of the measuring column is welded to the inner wall of the bucket, so that the connection is more precise and more secure.
[0008] More preferably, the bucket and the measuring column are both made of metal. Metal materials have higher connection strength and are not easy to break.
[0009] The beneficial effects of the utility model are as follows: an opening is provided at the lower end of the lifting bucket, and a rubber sheet is provided on the opening to cover the opening. During the process of pumping water, the lifting bucket is connected to the measuring column through the drilling rig, and the lifting bucket is extended below the circulating liquid surface. After the pumping is completed, the rubber sheet is covered with the opening by the pressure of the circulating liquid extracted from the lifting bucket, and then the lifting bucket is lifted by the rising of the measuring column driven by the drilling rig, so that the pumping of water can be completed quickly, thereby improving the efficiency of pumping water from the drilling circulating fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 The utility model is a schematic diagram of the water inlet structure at the lower end of the middle bucket.
[0012] Figure 3 It is a top view of the rubber sheet in the utility model. DETAILED DESCRIPTION
[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0014] like Figure 1-3 As shown, a field drilling circulating fluid rapid pumping device comprises a lifting bucket 1, a cylindrical measuring column 2 is arranged in the lifting bucket 1, and the lifting bucket 1 and the measuring column 2 are both made of metal. The connection strength of the metal material is higher and it is not easy to break.
[0015] Rubber sheets 3 are symmetrically arranged on the left and right sides of the bottom of the bucket 1. The opposite ends of the two rubber sheets 3 are fixedly connected to the inner side of the lower wall of the bucket 1 by screws 4. The bucket 1 has an opening at the corresponding position below the rubber sheet 3, and the size of the rubber sheet 3 is larger than the size of the opening.
[0016] The upper end of the measuring column 2 is connected to the drilling rig, and the drilling rig drives the bucket 1 to move up and down in the borehole to complete the water pumping. The lower end of the measuring column 2 is welded to the inner wall of the bucket 1. The connection is more precise and more secure. The upper outer surface of the measuring column 2 is set to be threaded and connected to the drilling rig. The upper outer surface of the measuring column 2 is set to be threaded for easy connection with the drilling rig. The rotation of the drilling rig drives the measuring column 2 and the bucket 1 to rise or fall quickly, thereby improving the water pumping efficiency. During the first water pumping, the water level in the borehole can be directly read according to the scale of the wetted position on the measuring column 2.
[0017] An opening is provided at the lower end of the lifting bucket 1, and a rubber sheet 3 is provided on the opening to cover the opening. During the pumping process, the lifting bucket 1 is connected to the measuring column 2 through the drilling rig, and the lifting bucket 1 is extended below the circulating liquid surface. After the pumping is completed, the rubber sheet 3 is covered with the opening by the pressure of the circulating liquid extracted from the lifting bucket 1, and then the lifting bucket 1 is lifted by the rising measuring column 2 driven by the drilling rig, so that the pumping can be completed quickly, thereby improving the efficiency of pumping the circulating fluid in the borehole.
[0018] The process of extracting the circulating fluid from the drilling hole is as follows: the lifting bucket 1 is lowered by the drilling rig and enters below the circulating fluid surface. At this time, the rubber sheet 3 covers the opening at the bottom of the lifting bucket 1. The pressure inside the lifting bucket 1 is lower than the pressure below the circulating fluid surface. The circulating fluid pushes the rubber sheet 3 upward and enters the lifting bucket 1 through the opening at the bottom of the lifting bucket 1.
[0019] The bucket 1 continues to descend until the bucket 1 is completely submerged under the liquid surface, part of the liquid enters the bucket 1 through the bottom opening, and part of the liquid enters the bucket 1 through the upper opening of the bucket 1. At this time, the bucket 1 is full of water.
[0020] The lifting bucket 1 is lifted upward by the drilling rig. When the lifting bucket 1 rises, the circulating liquid water pressure inside the lifting bucket 1 acts on the rubber sheet 3, and the rubber sheet 3 will cover the bottom opening, so that the bottom of the lifting bucket 1 is closed. The lifting bucket 1 continues to rise until it is out of the hole, and the circulating liquid in the bucket is discharged.
[0021] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
