Description

Technical Field

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] like Figure 1-15 As shown, the present invention has the following three specific embodiments

[0046] Example 1

[0047] A hydrogeological drilling and pumping device, comprising a soil layer 100 and a water layer 200 located below the soil layer 100, and also comprising a mounting tube 1, a driving motor 2, a drilling tube 3, a linkage mechanism, an extension tube 5, a fixing ring 6 and a support 7;

[0048] A short-circuit tube 11 is fixedly connected to the top of the installation tube 1, and openings 12 are evenly arranged on the lower circumference of the short-circuit tube 11. A first central axis 13 is rotatably connected to the center of the top plate of the installation tube 1, and a first lifting blade 14 is fixedly connected above the first central axis 13; a driving motor 2 is used to drive the first central axis 13 to rotate; a drill tube 3 is sleeved on the outside of the installation tube 1 and rotatably connected to the installation tube 1, and a screw-in blade 31 is fixedly connected to the outer wall of the drill tube 3; a linkage mechanism is used to transmit the power of the first central axis 13 to the drill tube 3; a plurality of extension tubes 5 are provided, and the center of the extension tube 5 is evenly arranged on the circumference. The support rod 51 is fixedly connected to a swivel seat 52, and the swivel seat 52 is symmetrically arranged up and down. A second central axis 53 is rotatably connected between the swivel seats 52, and a second lifting blade 54 is fixedly connected to the second central axis 53; the bottom extension tube 5 is connected to the short-circuit tube 11, and the two adjacent extension tubes 5 are connected through the fixing ring 6, and the bottom second central axis 53 is connected to the first central axis 13, and the two adjacent second central axes 53 are connected to each other; the bottom of the support 7 is fixedly connected to a support rod 71, and the bottom of the support rod 71 is anchored to the soil layer 100 through an anchor rod 72, and the extension tube 5 is slidably connected to the support 7.

[0049] Furthermore, a material guide seat 32 is fixedly connected to the top of the mounting tube 1, and the material guide seat 32 is located between the short-circuit tube 11 and the drill tube 3. The material guide seat 32 and the top of the side plate of the drill tube 3 and the bottom of the opening 12 are all inclined, and a disturbance rod 33 is evenly fixedly connected to the inner wall circumference of the side plate of the drill tube 3.

[0050] Furthermore, a cavity 21 is opened in the top plate of the mounting cylinder 1, a driven gear 22 is fixedly connected to the position corresponding to the cavity 21 on the first central axis 13, a hood 23 is fixedly connected to the lower surface of the top plate of the mounting cylinder 1, the drive motor 2 is fixed in the hood 23, the drive motor 2 is provided with a vertically upward output shaft 24, the output shaft 24 is rotatably connected to the top plate of the mounting cylinder 1, a driving gear 25 meshing with the driven gear 22 is fixedly connected to the output shaft 24, the number of teeth of the driving gear 25 is less than the number of teeth of the driven gear 22, the drive motor 2 is electrically connected to a wire 26, and the wire 26 passes through the top plate of the mounting cylinder 1 and the material guide seat 32.

[0051] Furthermore, grooves 81 are provided at the upper and lower ends of the extension tube 5 and the top of the short-circuit tube 11, and the fixing ring 6 is located in the grooves 81. Fixing screws 82 are symmetrically inserted into the outer wall of the fixing ring 6, and the fixing screws 82 are embedded. Fixing screw holes 83 are provided at positions corresponding to the fixing screws 82 on the grooves 81. The outer wall of the extension tube 5 and the outer wall of the fixing ring 6 are evenly provided with first guide grooves 84 and second guide grooves 85 on the circumference. The first guide grooves 84 and the second guide grooves 85 are staggered with the fixing screws 82. A through groove (not shown in the figure) is provided on the support 7. The extension tube 5 is movably inserted in the through groove. A guide block 86 is fixedly connected to the inner wall of the through groove. Square grooves 87 are provided on the tops of the first center axis 13 and the second center axis 53, and a square block 88 is fixedly connected to the bottom of the second center axis 53.

[0052] In this embodiment, Figure 1 As shown, when drilling and pumping are required, the support 7 is first fixed to the soil layer 100 by the anchor rod 72, the drill tube 3 is placed on the soil layer 100 and directly below the through groove, the extension tube 5 is inserted into the through groove, and the first guide groove 84 is slidably connected with the guide block 86, and then the fixing ring 6 is used to connect the extension tube 5 with the short-circuit tube 11.

[0053] like Figure 6 , 10 As shown in FIG. 15 , firstly, the bottom of the fixing ring 6 is placed in the groove on the short-circuit tube 11, and then the groove at the bottom of the extension tube 5 is inserted into the fixing ring 6, and the fixing screws 82 on the upper and lower sides of the fixing ring 6 are screwed into the fixing screw holes 83, so that the short-circuit tube 11 and the extension tube 5 are connected to each other through the fixing ring 6, as shown in FIG. Figure 3 As shown, the first center shaft 13 and the second center shaft 53 are connected by the cooperation of the square groove 87 and the square block 88 .

[0054] The drive motor 2 is connected to an external power source via a wire 26, so as to realize power supply to the drive motor 2. The wire 26 should have a sufficient reserved length, such as Figure 1 and 7As shown, the driving motor 2 drives the output shaft 24 and the driving gear 25 to rotate, and the driving gear 25 drives the driven gear 22 and the first center shaft 13 to rotate. Since the number of teeth of the driving gear 25 is less than the number of teeth of the driven gear 22, the first center shaft 13 rotates at a reduced speed, which can increase the output power of the first center shaft 13. The first center shaft 13 drives the drill tube 3 to rotate through the linkage mechanism, and the first center shaft 13 also drives the second center shaft 53 to rotate, so that the first lifting blade 14 and the second lifting blade 54 rotate.

[0055] Due to the limitation of the guide block 86, the drill tube 3 can only move vertically. When the drill tube 3 rotates, the soil is transported upward by the screw-in blade 31, thereby realizing the opening of the drilling well. The soil slides down through the top of the drill tube 3 and the guide seat 32, and enters the short-circuit tube 11 through the opening 12. The rotation of the first lifting blade 14 and the second lifting blade 54 transports the soil from bottom to top and discharges it from the outlet of the addition tube. Figure 2 and 8 As shown, the disturbance rod 33 disturbs the soil to prevent the soil from piling up on the material guide seat 32 and being unable to slide down.

[0056] When the top extension tube 5 is about to separate from the support 7, the drive motor 2 can be controlled to brake, and then a new extension tube 5 can be installed through the fixing ring 6. After installation, the first guide grooves 84 on the upper and lower extension tubes 5 should be aligned, and the second guide groove 85 on the fixing ring 6 should also be aligned with the first guide groove 84. The two adjacent second center axes 53 are also connected through the cooperation of the square block 88 and the square groove 87. According to the depth of the drilling well to be opened, the appropriate number of extension tubes 5 can be connected, and then the drive motor 2 can be started again to open the drilling well.

[0057] Example 2

[0058] The linkage mechanism includes a lifting plate 41, a linkage cylinder 42 and a pull rope 43; the lifting plate 41 is slidably connected to the installation cylinder 1, and a first spring 44 is evenly fixedly connected to the top plate of the lifting plate 41 and the installation cylinder 1. The linkage cylinder 42 is rotatably connected to the center of the lifting plate 41, and the first central axis 13 is movably inserted in the linkage cylinder 42. The outer wall of the first central axis 13 and the inner wall of the linkage cylinder 42 are respectively provided with a first linkage block 45 and a first linkage groove 46, and the upper surface of the bottom plate of the drill tube 3 is provided with a linkage hole 47, and the inner wall of the linkage hole 47 and the outer wall of the linkage cylinder 42 are respectively provided with a first linkage block 45 and a first linkage groove 46. A second linkage groove 48 and a second linkage block 49 are separately provided. The pull rope 43 is evenly arranged around the circumference. The bottom of the pull rope 43 is fixedly connected to the lifting plate 41. The pull rope 43 is slidably connected to the top plate of the mounting cylinder 1 and the material guide seat 32. A guide wheel 410 is rotatably connected to the position of the support 7 corresponding to the pull rope 43. A wire tube 411 is fixedly connected to the support 7. The pull rope 43 is slidably connected to the support 7, and the pull rope 43 passes through the wire tube 411 after being guided by the guide wheel 410. The free end of the pull rope 43 is fixedly connected to a lock seat 412, and the lock seat 412 is fixed to the support 7 by a locking screw 413.

[0059] Furthermore, when the lifting plate 41 contacts the top plate of the drill tube 3, the first spring 44 is in a natural state.

[0060] In this embodiment, the technical features of the linkage mechanism are disclosed, which is used to drive the drill tube 3 to rotate through the first central axis 13. Figure 1 , 5 , 8 and 9, in the initial state, under the action of the first spring 44, the lifting plate 41 moves to the bottom of the mounting tube 1, the bottom of the linkage tube 42 is inserted into the linkage hole 47, and the second linkage block 49 enters the second linkage groove 48. When the first center axis 13 rotates, the linkage tube 42 is driven to rotate through the cooperation of the first linkage block 45 and the first linkage groove 46, and the linkage tube 42 drives the drill tube 3 to rotate through the cooperation of the second linkage block 49 and the second linkage groove 48.

[0061] like Figure 1 and 4 As shown, the pull rope 43 passes through the wire tube 411 after being guided by the guide wheel 410, a lock seat 412 is fixed at the free end of the pull rope 43, and the lock seat 412 is fixed to the support 7 by a locking screw 413. The length of the pull rope 43 corresponds to the depth that needs to be opened in the drilling well, that is, when the drill tube 3 enters the water layer 200, the pull rope 43 is straightened, and the linkage tube 42 contacts the top of the installation tube 1.

[0062] When the device is working, the driving motor 2 drives the drill barrel 3 to rotate to realize the opening of the drilling well. The first lifting blade 14 and the second lifting blade 54 rotate to discharge the soil generated when the drilling well is opened, and the drill barrel 3 continues to descend. When the drill barrel 3 penetrates the soil layer 100 and enters the water layer 200, it will fall under the action of gravity. At this time, the pull rope 43 will lift the lifting plate 41 upward, and the first spring 44 is compressed until the linkage cylinder 42 contacts the top of the installation cylinder 1. At this time, the linkage cylinder 42 is separated from the linkage hole 47, and the drill barrel 3 loses power drive. The driving motor 2 drives the first lifting blade 14 and the second lifting blade 54 to rotate to empty the soil in the short-circuit cylinder 11 and the extension cylinder 5.

[0063] After the soil is emptied, clean water is discharged. When water pumping detection is required, the drive motor 2 is started, and the first lifting blade 14 and the second lifting blade 54 can lift the groundwater. A cover plate can be set on the top extension tube 5, and a water outlet pipe can be set on the cover plate to receive the groundwater.

[0064] Example 3

[0065] The upper surface of the lifting plate 41 is evenly fixed with a first push rod 91, which passes through the first spring 44. The first push rod 91 is slidably connected with the top plate of the installation tube 1 and the side plate of the short-circuit tube 11. The outer wall of the extension tube 5 is evenly provided with a storage groove 92. The storage groove 92 and the pull rope 43 are arranged alternately. The inner side of the storage groove 92 is provided with a slide groove 93. The inner side of the slide groove 93 is provided with a track groove 94. The track groove 94 is fixed with a track rod 95. The slide groove A plug hole 96 is provided at the bottom of 93, a flip plate 97 is rotatably connected to the top of the storage groove 92, an insertion rod 98 is fixedly connected to the bottom of the flip plate 97, a slider 99 is slidably connected in the slide groove 93, a track block 910 is fixedly connected to the slider 99, the track block 910 is slidably connected to the track rod 95, a second push rod 911 is fixedly connected to the top of the slider 99, the second push rod 911 is slidably connected to the side plate of the extension tube 5, and a connecting rod 912 is hinged between the slider 99 and the flip plate 97.

[0066] Furthermore, the flip plate 97 includes a first short plate 971 and a second short plate 972 that are separated from each other. The top of the first short plate 971 is rotatably connected to the top of the storage groove 92. The first short plate 971 is hinged to the connecting rod 912. A telescopic rod 973 is fixedly connected between the first short plate 971 and the second short plate 972, and a second spring 974 is sleeved on the telescopic rod 973.

[0067] Furthermore, when the slide seat is located at the bottom of the slide groove 93, the length of the second push rod 911 extending out of the extension tube 5 is equal to the length of the socket 96, and when the lifting plate 41 is located at the bottom of the mounting tube 1, the length of the first push rod 91 extending out of the short-circuit tube 11 is equal to the length of the socket 96.

[0068] In this embodiment, the device is only fixed by hanging the pull rope 43, which may cause excessive tension on the pull rope 43. To solve this problem, this embodiment discloses a flip plate 97 to assist in fixing the device.

[0069] like Figure 6 and 11 As shown, when the short-circuit tube 11 is connected to the extension tube 5, the first push rod 91 enters the insertion hole 96 in the bottom extension tube 5 and contacts the slider 99. Figure 12-13 As shown, when the extension tubes 5 are docked, in the initial state, under the action of gravity, the slider 99 is located at the bottom of the slide groove 93, and the flip plate 97 is in a vertical state. After the two extension tubes 5 are docked, the second push rod 911 at the bottom contacts the slider 99 at the top.

[0070] When the drill tube 3 penetrates the soil layer 100 and descends under the action of gravity, due to the superposition of multiple extensions, the gravity is large, so that the lifting plate 41 can rise until the linkage tube 42 contacts the top plate of the installation tube 1, and the bottom slider 99 is pushed up by the first push rod 91, and the remaining sliders 99 are pushed up by the second push rod 911. Fig.13 and 14 As shown, when the slider 99 rises, the connecting rod 912 drives the flip plate 97 to rotate outward, and the flip plate 97 abuts against the wall of the drilling well, so that the device is fixed by the flip plate 97.

[0071] Due to the large gravity caused by the stacking of multiple extension tubes 5, the rising height of the slider 99 and the rising height of the lifting plate 41 are fixed, and the rotation angle of the flip plate 97 is fixed. When the flip plate 97 rotates, the insertion rod 98 first enters the well wall. As the flip plate 97 continues to rotate, the telescopic rod 973 and the second spring 974 are compressed, ensuring that the insertion rod 98 can completely enter the well wall. The friction between the insertion rod 98 and the well wall can assist in fixing the device.

[0072] The working principle of the present invention is:

[0073] First, an extension tube 5 is slidably connected to the support 7, and the short-circuit tube 11 is docked with the bottom extension tube 5 through the fixing ring 6. The length of the pull rope 43 is set according to the depth of the drilling well to be opened, and the free end of the pull rope 43 is fixed.

[0074] When the driving motor 2 is working, it drives the first central shaft 13 to rotate, and the first central shaft 13 drives the drill tube 3 to rotate through the linkage mechanism to realize the opening of the drilling well. The soil generated during drilling enters the short-circuit tube 11, and the soil is output through the rotation of the first lifting blade 14 and the second lifting blade 54. In the process of opening the drilling well, the extension tubes 5 can be docked one by one through the fixing ring 6.

[0075] When the drill tube 3 penetrates the soil layer 100, the drill tube 3 descends under the action of gravity, the pull rope 43 lifts the lifting plate 41, the linkage cylinder 42 is separated from the linkage hole 47, the drill tube 3 loses power, and the flip plate 97 rotates outward to contact the well wall, and the flip plate 97 and the pull rope 43 jointly fix the device.
