Description

Technical Field

[0001] The present invention relates to the technical field of marine geological survey devices, and relates to a drilling device and a drilling method for marine geological survey and development. Background Art

[0002] The ocean covers an area of about 71% of the earth's surface area. It is an important part of the global geological structure and a natural laboratory for modern sedimentation. The seabed contains rich mineral resources and is an important resource base for humanity in the future. Marine environmental geology and disaster geology are directly related to human production and life. Marine geological survey is also the basis for seaport construction, submarine engineering, and submarine resource development. The seabed geomorphic landscape, its spatial distribution, and origin are one of the classic contents of marine geology. There are three main topographic units on the seabed, namely the continental margin, the ocean basin, and the mid-ocean ridge. The continental margin is the transitional part between the continent and the ocean and is a part of the seabed affected by both land and sea; the ocean basin is mainly composed of abyssal plains and abyssal hills, on which there are long sea ridges and isolated peak-shaped seamounts; Marine regional geological survey, like land regional geological survey, is an important part of a country's geological work, a sign of the degree of a country's marine geological work, and also the basis for work such as marine geological and mineral exploration and geological environmental protection. During marine geological survey, a drilling device is needed to conduct seabed drilling, and then sampling investigation and research are carried out. The current marine geological survey drilling devices require the assistance of a special drilling ship to complete, with relatively high drilling difficulty, and it is not convenient to collect samples of the drilled geology, and marine debris is prone to cause inconvenience to the collection.

[0013] The present invention also provides a drilling method for marine geological survey and development, which is characterized by including the following steps: S1. Place the device at the marine geology to be investigated, so that its stabilizing component contacts the geology to achieve stability. S2. Start its driving docking component, so that the drilling component descends. During the startup process, stabilize its driving. S3. When the drilling component descends, make its drill bit touch the geology for drilling. At the same time, buffer the descent during the descent to avoid the drill bit colliding with the geology due to too fast a descent speed. S4. The stabilizing component contacts the geology to limit the position of the main body of the drilling equipment, so as to prevent the drilling location of the device from shifting. S5. Then conduct an investigation on the marine geology. During the process of drilling and extracting the geology, let the geological soil enter the device. After the drilling of the geology is completed, take out the device and rotate it in the reverse direction to discharge the geology in the collection bin.

[0014] The beneficial effects of the present invention are reflected in: 1. When the main body of the drilling equipment is moved to the investigation location, the present invention places the device at the marine geology to be investigated, so that its stabilizing component contacts the geology to achieve stability, and starts the driver in its driving docking component, and the drilling component installed at its output end descends. The stable base and the drive base stabilize its drive. When the drilling assembly descends, the rotating column at the end drives the docking seat to descend, causing the drilling pressure plate to descend. Then, the drilling column drives the drill bit to contact the geology for drilling. At the same time, the drilling column causes the drill bit to rotate. When the docking seat descends, it drives its buffer plate to slide down along the side of the buffer column, causing the buffer plate to compress the lower buffer spring 1 and buffer spring 2, enabling the drill bit of the drilling assembly to buffer and descend, preventing the drill bit from colliding with the geology due to too fast a descent speed. The buffer assembly can buffer the stress during the drilling of the device, extending the service life of the device. When conducting an investigation on marine geology, the collection box controls the investigation assembly to rotate. During the process of drilling into the geology, the geological soil being drilled is affected by the rotation of the collection spiral blade, causing the geological soil to enter the device through the collection groove and the aggregate groove and being driven by the collection spiral blade to move towards the inside of the collection bin. The collection spiral blade is driven to rotate. After the geological drilling is completed, the device is taken out, causing the collection spiral blade to rotate in the reverse direction to discharge the geology in the collection bin.

[0015] 2. When the main body of the drilling equipment is moved to the investigation location, the stable seat at the bottom of the stable box of the stable component drives its stable column to contact the geology, enabling its control board to drive the stable column to rotate, causing the stable column to drill into the geology, limiting the position of the stable box and the main body of the drilling equipment, preventing the drilling location of the device from shifting. At the same time, the right stable column of the stable component also drills into the geology to limit the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present invention belongs.

[0021] The following is further described in detail with reference to the attached Figures 1 to 8 The present invention is further described as follows: A drilling device and a drilling method for marine geological survey and development, including the main body 1 of the drilling device. Inside the main body 1 of the drilling device, a drilling assembly 3 is fixedly installed. At the rear end of the drilling assembly 3, a stabilizing assembly 2 is installed. The stabilizing assembly 2 includes: a sealing plate 21, a control plate 22, a stabilizing base 23, a stabilizing column 24, a stabilizing box body 25, and a connecting wire harness 26.

Inside the sealing plate 21, a control plate 22 is installed. On the side of the stabilizing box body 25, a connecting wire harness 26 is installed. Below the stabilizing box body 25, a stabilizing base 23 is provided. Below the stabilizing base 23, a stabilizing column 24 is installed. Below the drilling assembly 3, a rotating column 31 is fixedly installed. The drilling assembly 3 includes a rotating column 31, a docking seat 32, a drilling pressure plate 33, a drilling column 34, and a drill bit head 35. Below the drilling assembly 3, a docking seat 32 is detachably installed. Below the docking seat 32, a drilling column 34 is detachably installed. Below the drilling column 34, a drilling pressure plate 33 is detachably installed.

[0022] Specifically, when moving the main body 1 of the drilling device to the investigation location, the device is placed at the marine geology to be investigated, so that its stabilizing assembly 2 contacts the geology for stabilization. When the stabilization is completed, the driver 51 in the docking assembly 5 is started, so that the drilling assembly 3 installed at its output end descends. At the same time, during the startup process, its stabilizing seat 54 and driving base 52 stabilize the driving. When the drilling assembly 3 descends, the rotating column 31 at its end drives the docking seat 32 to descend, so that its drilling pressure plate 33 descends. Then, the drilling column 34 drives the drill bit head 35 to contact the geology for drilling. At the same time, the drilling column 34 rotates the drill bit. At the same time, when the docking seat 32 descends, it drives the buffer plate 42 to slide down along the side of the buffer column 41, so that the buffer plate 42 presses the buffer spring one 43 and the buffer spring two 45 below, so that the drill bit head 35 of the drilling assembly 3 descends with buffering, avoiding the drill bit colliding with the geology due to too fast a descent speed.

[0023] Preferably, in this embodiment, a drill probe 35 is detachably installed below the drilling pressing plate 33, and a driving docking assembly 5 is fixedly installed above the rotating column 31. The driving docking assembly 5 includes a driver 51, a driving base 52, a mounting seat 53, a stabilizing seat 54, and a supporting baffle 55. The driver 51 is installed below the driving docking assembly 5, and the driving base 52 is detachably installed below the driver 51. The mounting seat 53 is installed below the driving base 52. A stabilizing seat 54 is provided on the side of the mounting seat 53, and a supporting baffle 55 is installed on the side of the stabilizing seat 54. A buffer assembly 4 is installed inside the supporting baffle 55. The buffer assembly 4 includes a buffer column 41, a buffer plate 42, a first buffer spring 43, a damping bottom plate 44, and a second buffer spring 45. The buffer column 41 is installed below the buffer assembly 4, the buffer plate 42 is slidably connected below the buffer column 41, the first buffer spring 43 is installed below the buffer plate 42, the second buffer spring 45 is installed below the buffer plate 42, and the damping bottom plate 44 is installed below the second buffer spring 45.

[0024] Specifically, when the main body 1 of the drilling equipment is moved to the investigation site, the stabilizing column 24 is driven by the stabilizing base 23 at the bottom of the stabilizing box body 25 of the stabilizing assembly 2 to contact the geology, so that the control board 22 drives the stabilizing column 24 to rotate, causing the stabilizing column 24 to drill into the geology to limit the positions of the stabilizing box body 25 and the main body 1 of the drilling equipment, preventing the drilling site of the device from shifting. At the same time, the stabilizing column 24 on the right side of the stabilizing assembly 2 also drills into the geology to limit the device.

[0025] Preferably, in this embodiment, an investigation assembly 6 is installed at the bottom of the main body 1 of the drilling equipment. A collection groove 61 is provided above the investigation assembly 6. A collection spiral blade 63 is fixedly installed on the side of the collection groove 61. The collection spiral blade 63 rotates forward and backward driven by a stepping motor. A collection bin 66 is provided on the side of the collection spiral blade 63. A fitting seat 67 is detachably installed at the front end of the collection bin 66. A protection column 62 is fixedly installed at the front end of the fitting seat 67. An aggregate groove 65 is provided on the side of the protection column 62. A docking plate 64 is fixedly installed at the front end of the protection column 62. A fixing assembly 7 is installed on the side of the main body 1 of the drilling equipment. A first fixing column 71 is provided below the fixing assembly 7. A fixing base 72 is installed at the bottom of the first fixing column 71. A second fixing column 74 is installed above the fixing base 72. An adjusting column 75 is installed at the front end of the second fixing column 74. A protection bottom plate 11 is installed on the side of the fixing base 72. An installation bottom plate 14 is installed on the side of the protection bottom plate 11. A collection box body 12 is installed above the installation bottom plate 14. An installation side plate 13 is installed on the side of the collection box body 12.

[0026] Specifically, during use, when conducting a survey of marine geology, the collection box 12 is controlled to rotate the survey component 6. During the process of drilling into the geology, the geological soil being drilled is affected by the rotation of the collection spiral blade 63, causing the geological soil to enter the device through the collection groove 61 and the aggregate groove 65, and being driven by the collection spiral blade 63 to move into the interior of the collection bin 66. The collection spiral blade 63 is driven to rotate. After the geological drilling is completed, the device is taken out, causing the collection spiral blade 63 to rotate in the reverse direction to discharge the geology in the collection bin 66.

[0027] When the drilling equipment and method for marine geological survey and development of the present invention are in use, when the main body 1 of the drilling equipment is moved to the survey location, the device is placed at the marine geology to be surveyed, and the stabilizing component 2 contacts the geology to stabilize it. When the stabilization is completed, the driver 51 in the drive docking component 5 is started, causing the drilling component 3 installed at its output end to descend. At the same time, during the startup process, the stabilizing seat 54 and the drive base 52 stabilize the drive. When the drilling component 3 descends, the rotating column 31 at its end drives the docking seat 32 to descend, causing the drilling pressure plate 33 to descend, and then the drilling column 34 drives the drill head 35 to contact the geology for drilling. At the same time, the drilling column 34 causes the drill bit to rotate. At the same time, when the docking seat 32 descends, it drives the buffer plate 42 to slide down along the side of the buffer column 41, causing the buffer plate 42 to compress the buffer spring one 43 and the buffer spring two 45 below, enabling the drill head 35 of the drilling component 3 to buffer and descend, preventing the drill bit from colliding with the geology due to too fast a descent speed. When the main body 1 of the drilling equipment is moved to the survey location, the stabilizing column 24 is driven by the stabilizing base 23 at the bottom of the stabilizing box 25 of the stabilizing component 2 to contact the geology, and the control board 22 drives the stabilizing column 24 to rotate, causing the stabilizing column 24 to drill into the geology to limit the positions of the stabilizing box 25 and the main body 1 of the drilling equipment, preventing the drilling location of the device from shifting. At the same time, the stabilizing column 24 on the right side of the stabilizing component 2 also drills into the geology to limit the device. Specifically, during use, when conducting a survey of marine geology, the collection box 12 is controlled to rotate the survey component 6. During the process of drilling into the geology, the geological soil being drilled is affected by the rotation of the collection spiral blade 63, causing the geological soil to enter the device through the collection groove 61 and the aggregate groove 65, and being driven by the collection spiral blade 63 to move into the interior of the collection bin 66. The collection spiral blade 63 is driven to rotate. After the geological drilling is completed, the device is taken out, causing the collection spiral blade 63 to rotate in the reverse direction to discharge the geology in the collection bin 66.
