Description

Technical Field

[0001] The utility model relates to the technical field of borehole water level measuring equipment, in particular to a rock and soil exploration borehole water level measuring device. Background Art

[0002] When conducting geotechnical exploration work, in order to detect the water level in the rock and soil respectively, it is often necessary to drill holes in the rock and soil and measure the water level in the borehole, and then it is necessary to use a borehole water level measuring device. The utility model patent with patent application number CN202020247465.8 discloses a geotechnical exploration borehole water level measuring instrument. The movable and fixed components are arranged to facilitate the movement and fixation of the measuring device, overcome the defects of the inconvenience of moving and fixing the traditional measuring instrument, and provide convenience for the operator. When the measuring device needs to be fixed, the first spiral rod is rotated to disengage it from the through hole, and then the hand wheel is turned to make the rotating rod drive the eccentric wheel to rotate. The eccentric wheel can be rotated by rotating the hand wheel, thereby driving the roller to rotate so that it is off the ground. When the measuring device needs to be moved, the eccentric wheel can be rotated by rotating the hand wheel, thereby driving the roller to rotate so that it supports the ground. The first spiral rod is rotated to insert it into the through hole, and the device can be moved. According to the technical scheme disclosed by the invention, the existing borehole water level measuring equipment cannot effectively protect the water level meter when it is used. When the rock and soil in the borehole collapses, the water level meter is easily crushed, which is not conducive to ensuring the safety of the water level meter. On the other hand, when the rock and soil in the borehole collapses and the equipment is stuck, the equipment is often unable to be removed, resulting in a waste of equipment.

[0003] Therefore, how to design a rock and soil exploration borehole water level measuring device has become our current problem to be solved. Utility Model Content

[0008] Furthermore, the screw is welded to the bottom of the water level gauge, and a screw opening is provided on the inner side of the circular plate, and the screw opening is sleeved on the outer side of the screw.

[0009] Furthermore, an internal thread is provided on the inner side of the screw mouth, and an external thread is provided on the screw rod, and the internal thread matches the external thread.

[0010] Furthermore, the bottom end of the support plate is clamped on the outer side of the top of the circular plate, and the top end of the cone sleeve is sleeved on the outer side of the bottom of the circular plate.

[0011] Furthermore, the block is welded to the inner wall of the support plate, a bayonet is opened on the inner side of the circular plate, the insertion rod is clamped on the inner side of the bayonet, the top end of the insertion rod is welded to the bottom of the block, and the block is clamped on the top of the circular plate.

[0013] Beneficial effects: 1. When the geotechnical exploration borehole water level measuring device is working, the cone sleeve and the support plate are inserted into the inner side of the borehole, and the water in the borehole flows to the inner side of the support plate through the gap between the support plates, and then the water level in the borehole is measured in real time by using the water level meter, and it is fixed to the top of the borehole through the support plate. When the rock and soil around the borehole collapses, the cone sleeve and the support plate can be effectively used to support the collapsed rock and soil, avoiding damage to the water level meter due to squeezing, thereby ensuring the safety of the water level meter.

[0014] 2. When the geotechnical exploration borehole water level measuring device is in use, when the support plate cannot be removed due to the collapse of the rock and soil in the borehole, the fixing bolts on the top of the support plate are removed, and then the support plate and the sleeve plate are pulled upward from the top of the support plate, and then the water level gauge is rotated. The water level gauge drives the screw to rotate and pushes the circular plate downward, so that the circular plate drives the wedge block to move downward to the bottom of the wedge groove.

The top end of the support plate 5 is installed on the inner side of the socket 4 by bolts. The support plates 5 are evenly distributed on the outer side of the water level gauge 1. When in use, the cone sleeve 6 and the support plate 5 are inserted into the inner side of the borehole. The water in the borehole flows to the inner side of the support plate 5 through the gap between the support plates 5. Then, the water level gauge 1 is used to measure the water level in the borehole in real time, and is fixed to the top of the borehole through the support plate 1. When the rock and soil around the borehole collapses, the cone sleeve 6 and the support plate 5 can be effectively used to support the collapsed rock and soil, thereby avoiding damage to the water level gauge 1 due to squeezing, thereby ensuring the safety of the water level gauge 1.

[0023] In this embodiment, the screw rod 7 is welded to the bottom of the water level gauge 1, a screw mouth 9 is provided on the inner side of the circular plate 8, and the screw mouth 9 is sleeved on the outer side of the screw rod 7. An internal thread is provided on the inner side of the screw mouth 9, and an external thread is provided on the screw rod 7. The internal thread matches the external thread.

When the rock and soil around the borehole collapses, the cone sleeve 6 and the support plate 5 can be effectively used to support the collapsed rock and soil, so as to avoid damage to the water level meter 1 due to squeezing, thereby ensuring the safety of the water level meter 1. When the support plate 5 cannot be taken out due to the collapse of the rock and soil in the borehole When the water level gauge 1 is in operation, the fixing bolts on the top of the support plate 5 are removed, and the support plate 2 and the sleeve plate 3 are pulled upward from the top of the support plate 5, and then the water level gauge 1 is rotated. The water level gauge 1 drives the screw rod 7 to rotate and pushes the circular plate 8 downward, so that the circular plate 8 drives the wedge block 14 to move downward to the bottom of the wedge groove 13. At the same time, the plug rod 11 on the stopper 10 is moved out from the inner side of the bayonet 12, so that the water level gauge 1 loses the fixation of the circular plate 8, and the support plate 5 loses the support of the circular plate 8, and then the water level gauge 1 and the support plate 5 are taken out. Only the cone sleeve 6 needs to be left on the inner side of the borehole, so as to avoid the equipment being unable to be recovered due to the collapse of the borehole and reduce the waste of equipment.
