Technical Field

[0001] The utility model relates to the technical field of devices for geological core drilling, in particular to a flushing fluid collecting device for geological core drilling. Background Art

[0002] Geological core drilling is a type of drilling, aiming to obtain cores below the surface by using drilling machinery and technology, mainly for reliable evaluation of geological and mineral resource parameters. Geological core drilling not only includes basic drilling work, but also involves the taking and preservation of cores to ensure an accurate understanding of the underground geological conditions. The purpose of geological core drilling is to drill core samples to study the age, lithology, sedimentary characteristics of strata, as well as the physical, chemical properties and ore-bearing characteristics of reservoirs, so as to provide basic data and support for fields such as resource exploration, oilfield development, and mineral resource evaluation.

[0003] As a typical process, in the process of core sampling with wireline coring, the wire rope will be stained with the flushing fluid in the hole. When the operator operates the winch to wind and unwind the wire rope, a part of the flushing fluid on the wire rope will penetrate into the ground, causing soil pollution, and the other part will splash onto the operator's body and spill onto the operating platform, bringing inconvenience to the operator's operation. Content of the Utility Model

[0004] The utility model aims to provide a flushing fluid collecting device for geological core drilling to solve the problems that the flushing fluid on the wire rope during the core sampling process spills onto the machine table board and splashes onto the body of the winch operator, and at the same time, it avoids the pollution of the soil caused by the penetration of the flushing fluid into the ground.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A flushing fluid collecting device for geological core drilling includes a frame. A drum is rotatably connected to the frame through a rotating shaft. The drum is used for winding and unwinding the wire rope. One end of the rotating shaft is connected with a driving device. A liquid collecting funnel is connected to the frame. The liquid collecting funnel is located below the drum, and the opening of the liquid collecting funnel faces the drum. An arc-shaped baffle is detachably connected to the frame through a connecting piece. The inner diameter of the arc-shaped baffle is larger than the diameter of the drum. The arc-shaped baffle covers the drum, and the axis of the arc-shaped baffle extends along the axis of the drum. One side of the arc-shaped baffle extends into the liquid collecting funnel, and the other side of the arc-shaped baffle is higher than the vertex of the drum. A drain pipe is connected to the bottom of the liquid collecting funnel, and the free end of the drain pipe leads to a sedimentation tank.

[0007] Further, the connecting piece includes a mounting post arranged on the frame. A mounting sleeve is connected to the outer wall of the arc-shaped baffle. The mounting post is slidably connected to the mounting sleeve.

[0008] Further, the frame includes three trapezoidal frames arranged side by side, at least one cross bar is connected to the three trapezoidal frames, and the mounting post is connected to the cross bar.

[0009] Further, the cross-sectional shape of the arc-shaped baffle is a semi-circle or five-sixths of a semi-circle.

[0010] Further, the cross-sectional shape of the liquid collecting funnel is trapezoidal.

[0011] Principle and beneficial effects of the technical solution:

[0012] (1) The frame of the present utility model is used to install various components. A roller is rotatably connected to the frame through a rotating shaft. One end of the rotating shaft is connected to a driving device. The driving device drives the rotating shaft to rotate, and the rotating shaft drives the roller to rotate, thereby realizing the winding and unwinding of the steel wire rope; an arc-shaped baffle is connected to the frame. The axis of the arc-shaped baffle extends along the axis of the roller. The diameter of the arc-shaped baffle is larger than the diameter of the roller, and one side of the arc-shaped baffle extends into the liquid collecting funnel, and the other end is higher than the vertex of the roller. The vertex of the roller refers to the highest point in the vertical direction where the roller is installed on the frame. In this way, when the roller winds and unwinds the steel wire rope, the flushing liquid on the steel wire rope will be blocked by the arc-shaped baffle, avoiding the flushing liquid from splashing onto the body of the operator and spilling onto the operating machine table, increasing the convenience of the operator's operation; and a liquid collecting funnel is connected to the frame. The liquid collecting funnel is located below the roller. The flushing liquid dripping from the steel wire rope and the flushing liquid blocked back by the arc-shaped baffle flow into the liquid collecting funnel and flow into the sedimentation tank through the drain pipe for treatment. In this way, it can avoid the flushing liquid on the steel wire rope from directly flowing into the ground and polluting the soil, reducing environmental pollution;

[0013] (2) The liquid collecting funnel of the present utility model is detachably connected to the cross bar of the frame through a mounting post and a mounting sleeve. During installation, only need to put the mounting sleeve on the mounting post until the lower end of the mounting sleeve abuts against the cross bar of the frame, which increases the installation convenience and can also ensure sufficient connection strength; the frame adopts a combination of trapezoidal frames and cross bars. Cross bars are respectively connected to the two side bars of the trapezoidal frame. The cross bar can be used to install the mounting post and can also increase the strength of the trapezoidal frame, which not only increases the stability of the device but also reduces the material consumption and saves costs; the cross-section of the arc-shaped baffle is a semi-circle or five-sixths of a semi-circle, which can further block the splashing flushing liquid, and the cross-section of the liquid collecting funnel is trapezoidal, which can make the flushing liquid flow smoothly downward into the drain pipe.

[0019] The present utility model will be further described in detail below in conjunction with the attached drawings and implementation manners:

[0020] As Figures 1 to 3 shown, a flushing fluid collecting device for drilling includes a frame. The frame includes three trapezoidal frames 1 arranged side by side. Cross bars 3 are respectively connected to the side rods on the three trapezoidal frames 1. A drum 9 is rotatably connected to the frame through a rotating shaft. The drum 9 is located between two adjacent trapezoidal frames 1. The drum 9 is used for winding and unwinding a steel wire rope 91. One end of the rotating shaft is connected to a driving device 8. The driving device 8 is a motor. The driving device 8 can be installed on another trapezoidal frame 1; A liquid collecting funnel 4 is welded and connected to the frame. The cross-sectional shape of the liquid collecting funnel 4 is trapezoidal. The liquid collecting funnel 4 is located below the drum 9, and the opening of the liquid collecting funnel 4 faces the drum 9; An arc-shaped baffle 2 is detachably connected to the frame through a connecting member. The cross-sectional shape of the arc-shaped baffle 2 is a semi-circle or five-sixths of a semi-circle. Among them, the connecting member includes a mounting post 31 arranged on the cross bar 3 of the frame. An mounting sleeve 21 is connected to the outer wall of the arc-shaped baffle 2. The mounting post 31 is slidably connected to the mounting sleeve 21. The inner diameter of the arc-shaped baffle 2 is larger than the diameter of the drum 9. The arc-shaped baffle 2 covers the drum 9. The axis of the arc-shaped baffle 2 extends along the axis of the drum 9. One side of the arc-shaped baffle 2 extends into the liquid collecting funnel 4. The other side of the arc-shaped baffle 2 is higher than the vertex of the drum 9; A drain pipe 5 is connected to the bottom of the liquid collecting funnel 4. The free end of the drain pipe 5 leads to a sedimentation tank 6.

[0021] The specific implementation process is as follows:

[0022] Install the device, start the driving device 8. The driving device 8 drives the rotating shaft to rotate. The rotating shaft drives the drum 9 to rotate. The operator stands on the side where the arc-shaped baffle 2 is located and controls the rotation speed and rotation direction through the operating rod 7 to realize the winding of the steel wire rope 91. The flushing fluid on the steel wire rope 91 hits the arc-shaped baffle 2 and flows into the liquid collecting funnel 4 along the inner wall of the arc-shaped baffle 2, and then flows into the sedimentation tank 6 through the drain pipe 5.

[0023] Among them, the frame of the present utility model is used to install various components. A roller 9 is rotatably connected to the frame through a rotating shaft. One end of the rotating shaft is connected to a driving device 8. The driving device 8 drives the rotating shaft to rotate, and the rotating shaft drives the roller 9 to rotate, so as to realize the winding and unwinding of the steel wire rope 91. An arc-shaped baffle 2 is connected to the frame. The axis of the arc-shaped baffle 2 extends along the axis of the roller 9. The diameter of the arc-shaped baffle 2 is larger than the diameter of the roller 9. One side of the arc-shaped baffle 2 extends into the liquid collecting funnel 4, and the other end is higher than the vertex of the roller 9. The vertex of the roller 9 refers to the highest point in the vertical direction when the roller 9 is installed on the frame and wrapped with the steel wire rope 91. In this way, when the roller 9 winds and unwinds the steel wire rope 91, the flushing liquid on the steel wire rope 91 will be blocked by the arc-shaped baffle 2 and flow into the liquid collecting funnel 4 along the inner wall of the baffle 2, avoiding the flushing liquid from splashing onto the body of the operator and spilling onto the operating machine table, and increasing the convenience of the operator's operation. And a liquid collecting funnel 4 is connected to the frame. The liquid collecting funnel 4 is located below the roller 9. The flushing liquid dripping from the steel wire rope 91 and the flushing liquid blocked back by the arc-shaped baffle 2 flow into the liquid collecting funnel 4 and flow into the sedimentation tank 6 through the drain pipe 5 for treatment. In this way, it can be avoided that the flushing liquid on the steel wire rope directly flows into the ground to pollute the soil, reducing environmental pollution.
