Abstract
Description
Technical Field
[0001] The utility model relates to the field of exploration technology, in particular to a drainage device suitable for exploration drilling. Background Art
[0002] During the survey, in order to measure the accurate original groundwater level in the borehole, it is necessary to remove the residual water in the drilling process. In the prior art, a bucket with a weight greater than the buoyancy of water is usually used to collect the water in the borehole after sinking due to gravity. If the bucket used in this method is to improve the water extraction efficiency and increase the amount of water extracted at one time, the weight of the bucket needs to be increased, and the residual water close to the length of the bucket from the bottom of the hole cannot be removed, which has a certain impact on the accuracy of measuring the water level in the borehole. Utility Model Content
[0003] The utility model aims to solve the problem in the prior art that when water in a prospecting borehole is scooped out by a bucket, there is a lot of residual water, which affects the accuracy of subsequent surveys, and provides a drainage device suitable for prospecting boreholes.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A drainage device suitable for surveying drilling holes comprises a cylinder and a float. A vertical water inlet is provided at the bottom of the cylinder. The diameter of the float is larger than the diameter of the water inlet. The density of the float is larger than the density of water. The water inlet can be opened when the float is away from the water inlet, and can be closed when the float abuts against the water inlet.
[0006] The utility model discloses a drainage device suitable for surveying boreholes. By opening a vertically arranged water inlet at the bottom of the cylinder, the water inlet is closer to the bottom of the drainage device, and the residual water in the borehole can be drained more easily. The water inlet can be opened or closed by the cooperation of the float and the water inlet. The device is placed in a borehole containing residual water. After the cylinder itself can sink into the water, the water pressure difference inside and outside the cylinder can lift the float to open the water inlet, so that the water in the borehole flows into the cylinder. Since the diameter of the float is greater than the diameter of the water inlet and the density is greater than the density of water, the float can sink to close the water inlet. When the cylinder containing residual water is lifted up, the water pressure inside can better ensure the close contact between the float and the water inlet to prevent leakage, thereby achieving the purpose of taking water from the borehole. The device is more convenient in extracting residual water in the borehole, and it is also easier to drain the residual water, which is conducive to accurately measuring the groundwater level of the site and effectively improving the accuracy of the survey design.
[0007] In order to ensure that the float can sink to the water inlet in the water, methods such as making the water inlet position as low as possible (funnel-shaped, etc.) and providing a limiting structure above the water inlet (such as a filter, guide plates arranged at intervals, etc.) can be adopted.
[0008] Preferably, the cylinder comprises a cylinder body and a base which are connected to each other, and the water inlet is arranged on the base.
[0009] Further preferably, the base has a counterweight.
[0010] It can make it easier to lower the cylinder to the bottom of the borehole, so that the residual water can be drained away, and the capacity of the drainage device can be selected according to needs.
[0011] Further preferably, the barrel is an iron component or a rubber component.
[0012] Preferably, the cylinder is also provided with a drain outlet.
[0013] Further preferably, the drain outlet is located at the top of the cylinder.
[0014] Further preferably, the distance between the water inlet and the bottom surface of the cylinder is less than or equal to 5 cm.
[0015] Further preferably, the top of the cylinder has a first anti-collision plate, the bottom of the cylinder has a second anti-collision plate, and the second anti-collision plate is a flexible component.
[0016] Effectively protect the drainage device, the flexible second anti-collision plate avoids affecting the extraction of residual water. The second anti-collision plate can be made of materials such as rubber, PU, PVC, etc.
[0017] Further preferably, the first anti-collision plate and the second anti-collision plate are both arc-shaped structures, and one end of the first anti-collision plate away from the cylinder and one end of the second anti-collision plate away from the cylinder are both inwardly arranged.
[0018] The above arrangement can further avoid damaging the drilled hole. Of course, the inward setting of the second anti-collision plate will not be set too small to affect water inlet.
[0019] Further preferably, a hook is provided on the first anti-collision plate.
[0020] Further preferably, there are at least two hooks, and the hooks are evenly distributed along the circumference of the first anti-collision plate.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0022] 1. A drainage device suitable for surveying boreholes according to the utility model is adopted. By opening a vertically arranged water inlet at the bottom of the cylinder, the water inlet is closer to the bottom of the drainage device, and the residual water in the borehole can be drained more easily. The water inlet can be opened or closed by the cooperation of the float and the water inlet. The device is placed in the borehole containing residual water. After the cylinder itself can sink into the water, the water pressure difference inside and outside the cylinder can lift the float to open the water inlet, so that the water in the borehole flows into the cylinder. Since the density of the float is greater than the density of water, it can sink to close the water inlet. When the cylinder containing residual water is lifted up, the water pressure inside it can better ensure the close contact between the float and the water inlet to prevent leakage, thereby achieving the purpose of extracting water from the borehole. The device is more convenient in the use of extracting residual water in the borehole, and it is also easier to drain the residual water, which is conducive to accurately measuring the groundwater level of the site and effectively improving the accuracy of the survey design.
