Description

Technical Field

[0002] Groundwater pollution mainly refers to the phenomenon that human activities cause changes in the chemical composition, physical properties and biological characteristics of groundwater, resulting in a decline in quality. The strata below the surface are complex and the groundwater flows extremely slowly. Therefore, groundwater pollution has the characteristics of slow process, difficult to detect and difficult to control. Once groundwater is polluted, even if the source of pollution is completely eliminated, it will take more than ten years or even decades for the water quality to recover. In order to understand the location of the groundwater pollution source, drilling equipment is needed to drill and take samples.

[0003] The drilling equipment currently used uses an electric push rod to adjust the inclination angle of the drill rod. The first motor works through a set screw to adjust the working depth of the drill rod.

[0037] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

The bottom of the longitudinal rotating shaft 3 is located in the cylinder 2 and has a conveying blade 4. The longitudinal rotating shaft 3 is also connected to the shaft end of the driving motor 6 installed on the fixed plate 1; the two-way drive mechanism 100 is arranged in the fixed plate 1, and the two-way drive mechanism 100 is transmission-connected to the longitudinal rotating shaft 3 so as to push the continuous toggle mechanism on both sides when the longitudinal rotating shaft 3 rotates. 200 and the intermittent detection mechanism 300 move synchronously; the continuous shifting mechanism 200 and the intermittent detection mechanism 300 are both slidably installed on the fixed plate 1, and when moving with the longitudinal rotating shaft 3, the continuous shifting mechanism 200 is provided to shift out the material conveyed by the conveying blade 4, and at the same time, the intermittent detection mechanism 300 realizes real-time detection of the material; the depth adjustment mechanism 400 is installed on the outside of the cylinder 2, and the depth adjustment mechanism 400 is driven by an external motor to facilitate adjustment of the drilling depth of the cylinder 2 during operation; the floating adjustment mechanism 500 is installed on the depth adjustment mechanism 400, and the floating adjustment mechanism 500 moves synchronously with the depth adjustment mechanism 400, and overcomes the influence of vibration during the lifting and lowering of the depth adjustment mechanism 400 and the cylinder 2.

[0039] In one example of the present invention, the drilling equipment is arranged on an external walking platform to facilitate the movement of the drilling equipment. In addition, the walking platform and the side frame 21 can be connected by an arc-shaped telescopic member to facilitate the adjustment of the inclination angle of the entire equipment before and after drilling, thereby facilitating storage and transportation before and after drilling.

[0040] like Figure 1 and Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, the bidirectional driving mechanism 100 includes a driving gear 7 , a connecting gear 8 , a pushing member 9 and an elastic supporting member 10 ;

[0041] The driving gear 7, the connecting gear 8, the pushing member 9 and the elastic support member 10 are all symmetrically arranged in the space inside the fixed plate 1, wherein the driving gear 7 is fixedly connected to the longitudinal rotating shaft 3, the driving gear 7 is meshed with the connecting gear 8, and the pushing member 9 is fixedly installed on the shaft end of the connecting gear 8;

[0042] The elastic support member 10 is arranged on the outside of the pushing member 9 , and the elastic support members 10 on both sides are respectively in contact with the continuous dialing mechanism 200 and the intermittent detection mechanism 300 .

[0043] In one embodiment of the present invention, the longitudinal rotating shaft 3 drives the driving gear 7 at the corresponding position to rotate synchronously when rotating. Since the driving gear 7 is engaged with the connecting gear 8, it can drive the connecting gear 8 and the pushing member 9 to rotate. When the pushing members 9 on both sides rotate, they push the movable rod 11 and the movable rod 2 17 at the corresponding position to slide along the fixed plate 1, and the elastic support member 10 is elastically deformed under the force.

[0044] like Figure 1 、 Figure 2 and Figure 3 As shown in FIG. 1 , as another preferred embodiment of the present invention, the continuous toggle mechanism 200 includes a movable rod 11 , a guide groove 12 , a horizontal rod 13 , a scraper 14 , a limit block 15 and a baffle 16 ;

[0045] The movable rod 11 is slidably connected to the guide groove 12 provided on the fixed plate 1. The movable rod 11 is located between the pusher 9 and the elastic support 10. Both sides of the movable rod 11 abut against the pusher 9 and the elastic support 10 respectively.

[0046] A horizontal rod 13 is fixedly installed at the bottom end of the movable rod 11, a scraper 14 is installed at the end of the horizontal rod 13, and a limit block 15 arranged at the free end of the horizontal rod 13 is slidably connected to the limit groove set on the scraper 14, and a baffle 16 is installed in the limit groove on the scraper 14.

[0047] In one example of the present invention, when the movable rod 11 is forced to slide along the guide groove 12, the horizontal rod 13 and the scraper 14 move synchronously therewith, and the scraper 14 moves along the gap of the conveying blade 4. At the same time, the limit block 15 set at the end of the horizontal rod 13 slides along the limit groove to push the upward conveyed material outward.

[0048] like Figure 1 As shown, as another preferred embodiment of the present invention, the intermittent detection mechanism 300 includes a second movable rod 17, a second guide groove 18, a detection pin 19 and a socket 20;

[0049] The movable rod 2 17 is installed on the fixed plate 1, and the movable rod 2 17 is slidably connected to the guide groove 2 18 provided on the fixed plate 1;

[0050] One side of the movable rod 17 abuts against the pusher 9, and the other side of the movable rod 17 abuts against the elastic support member 10;

[0051] A detection pin 19 is fixedly mounted on the inner side of the bottom end of the movable rod 2 17 , and the detection pin 19 is slidably connected to a socket 20 provided on the fixed plate 1 so as to be inserted into the cylinder 2 for detection.

[0052] In one embodiment of the present invention, when the movable rod 17 is forced to move along the guide groove 18, the detection needle 19 moves synchronously therewith. The detection needle 19 is intermittently inserted into the cylinder 2 to perform real-time detection of the material transported upward.

[0053] like Figure 1 、 Figure 4 and Figure 5 As shown in FIG. 4 , as another preferred embodiment of the present invention, the depth adjustment mechanism 400 includes a side frame 21 , a driving screw 22 , a movable block 23 , a horizontal rod 24 and an oblique rod 25 ;

[0054] The side frame 21 is arranged on the side of the cylinder 2 and is offset from the fixed plate 1. A driving screw 22 is rotatably installed in the side frame 21, and a movable block 23 is arranged on the driving screw 22. A horizontal rod 24 is slidably installed in the movable block 23;

[0055] An oblique rod 25 is fixedly installed on both sides of the horizontal rod 24, and the end of the oblique rod 25 is fixedly connected to the cylinder 2.

[0056] In one example of the present invention, the driving screw 22 rotates along the side frame 21 under the drive of an external motor. When rotating, the driving screw 22 pushes the movable block 23, the horizontal rod 24, the inclined rod 25 and the cylinder 2 to move synchronously along the height direction, thereby dynamically adjusting the drilling depth.

[0057] like Figure 4 、 Figure 5 and Figure 6 As shown, as another preferred embodiment of the present invention, the floating adjustment mechanism 500 includes a second inclined rod 26, a positioning pile 27, a longitudinal groove 28, a longitudinal groove 28, an elastic sleeve 29, a roller 30 and a pad 31;

[0058] The second oblique rod 26 is fixedly mounted on the outside of the first oblique rod 25, and a positioning pile 27 is provided at the end of the second oblique rod 26. The positioning pile 27 is also slidably connected to a longitudinal groove 28 provided in the driving screw 22, and the width of the longitudinal groove 28 is greater than the diameter of the positioning pile 27.

[0059] The elastic sleeve 29 is fixedly mounted on both sides of the movable block 23, and the free end of the elastic sleeve 29 is rotatably mounted with a roller 30, which abuts against the second inclined rod 26;

[0060] The pad 31 is disposed in a groove in the movable block 23 for the horizontal rod 24 to move.

[0061] In one example of the present invention, when the drilling equipment gets stuck during operation, the cylinder 2 drives the horizontal rod 24 and the inclined rod 1 25 to rise and fall locally along the movable block 23. On the one hand, the pad 31 is deformed by the force. On the other hand, the inclined rod 1 25 also drives the inclined rod 26 to move. The inclined rod 26 pushes the roller 30 to move along the elastic sleeve 29. The elastic parts inside the elastic sleeve 29 are matched with the damper to reduce the impact of vibration. At the same time, the positioning pile 27 slides along the longitudinal groove 28, thereby ensuring that the drilling equipment vibrates locally to prevent damage to the drilling components.

[0062] To sum up, the driving screw 22 rotates along the side frame 21 under the drive of the external motor. When rotating, the driving screw 22 pushes the movable block 23, the horizontal rod 24, the inclined rod 1 25 and the cylinder 2 to move synchronously in the height direction to adjust the drilling depth. The driving motor 6 drives the longitudinal rotating shaft 3 and the conveying blade 4 to rotate, and the material at the bottom moves upward along the inner wall of the cylinder 2. When a jam occurs, the cylinder 2 drives the horizontal rod 24 and the inclined rod 1 25 to move partially along the movable block 23. The inclined rod 1 25 also drives the inclined rod 2 26 to move. The inclined rod 2 26 pushes the roller 30 to move along the elastic sleeve 29. The elastic parts inside the elastic sleeve 29 are matched with the damper to reduce the impact of vibration. When the longitudinal rotating shaft 3 rotates, it drives the driving gear 7 at the corresponding position to rotate synchronously. Since the driving gear 7 is engaged with the connecting gear 8, it can drive the connecting gear 8 to rotate and the pushing member 9 to rotate. The pushing member 9 on one side The movable rod 11 is pushed to slide along the guide groove 12, and the horizontal rod 13 and the scraper 14 move synchronously therewith. The scraper 14 moves along the gap of the conveying blade 4. The limit block 15 set at the end of the horizontal rod 13 slides along the limit groove to push the upward conveyed material outward. The pushing member 9 on the other side pushes the movable rod 2 17 to move along the guide groove 2 18, and the detection needle 19 moves synchronously therewith. The detection needle 19 is intermittently inserted into the cylinder 2 to perform real-time detection of the material conveyed upward; this drilling equipment can not only adjust the drilling depth during drilling, but also avoid jamming and damage of components during the drilling process, thereby providing effective protection for the workpiece in the drilling area; in addition, during the drilling process, different depths can be detected in real time and automatically pushed out, while avoiding accumulation on the longitudinal rotating shaft 3 and the conveying blade 4, without manual cleaning, thereby greatly improving the application value of the equipment.
