Description

Technical Field

[0001] The invention belongs to the technical field of geological drilling, and in particular relates to a foldable drilling device for geological exploration. Background Art

[0002] In geological survey operations, groundwater sampling is usually required to investigate hydrogeology, groundwater resources, geothermal hot spring resources, etc. When investigating groundwater, it is necessary to drop the drilling pipe from top to bottom to the ground, so that the soil and rocks are squeezed into the drilling pipe, and then the soil and rocks in the pipe are led out and dropped again, and the cycle is repeated until the water flows out to complete the groundwater collection and sampling. For the falling pipe, its height will be adjusted so that the drilling pipe has a higher impact force, thereby ensuring the groundwater collection effect. Among them, for the height adjustment of the drilling pipe, the staff needs to set up additional brackets on the supporting bracket to increase the height. In order to ensure the stability of the device, the bracket needs to be tilted. For the tilted bracket, the staff needs to add brackets, fix the angles of the brackets respectively, and connect and fix multiple brackets. This operation method reduces the convenience of the drilling device when using it, and makes the degree of automation of the drilling device insufficient. Summary of the invention

[0037] Working principle: Determine in advance the height that the top plate 316 needs to be at, with the distance from the top of the secondary support rod 33 to the bottom of the primary support rod 31 as the side, half of the spacing between the bottom ends of the left and right groups of primary support rods 31 as the first right-angled side, and the horizontal height between the top of the secondary support rod 33 and the bottom end of the primary support rod 31 as the second right-angled side. For the first right-angled side, since the spacing between the bottom ends of the left and right groups of primary support rods 31 remains unchanged, the value of the first right-angled side is constant. When determining the required height of the top plate 316, since the horizontal height between the top of the secondary support rod 33 and the top plate 316 is constant, the height that the top plate 316 needs to be at plus the sum of the horizontal heights between the top of the secondary support rod 33 and the top plate 316 is determined as the value of the second right-angled side. According to the Pythagorean theorem, determine the value that needs to be set for the distance from the top of the secondary support rod 33 to the bottom end of the primary support rod 31.

[0038] When it is necessary to raise the height of the top plate 316 to a preset value, the secondary drive motor 45 is turned on to rotate the primary gear 46, thereby driving the two sets of secondary gears 47 and the screw 42 to rotate. When the screw 42 rotates, the thread on its outer side will drive the movable plate 43 on the left to move left and the movable plate 43 on the right to move right, thereby increasing the distance between the left and right sets of movable plates 43, changing the angle between the primary support rod 31 and the bottom frame 1, achieving the effect of folding the primary support rod 31 and facilitating the extension of the secondary support rod 33. At this time, the contact switch 53 is separated from the vertical plate 51 on the right, and the contact switch 53 transmits a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the primary drive motor 39 to turn on, so that the drive screw 311 rotates, and cooperates with the threaded hole 310 to make the top of the secondary support rod 33 extend. The telescopic cavity 32 gradually reduces the distance between the top ends of the two groups of secondary support rods 33 due to the tilted state of the primary support rod 31. When the laser rangefinder 38 cooperates with the reflector 37 to monitor that the distance from the top end of the secondary support rod 33 to the bottom end of the primary support rod 31 reaches a preset value, the laser rangefinder 38 transmits the data to the external terminal. The external terminal receives the data and controls the primary drive motor 39 to turn off and the secondary drive motor 45 to drive the primary gear 46 to rotate in the opposite direction, so that the distance between the left and right groups of movable plates 43 is reduced until the contact switch 53 contacts the vertical plate 51 on the right side. The contact switch 53 transmits the signal to the external terminal. The external terminal receives the signal and controls the secondary drive motor 45 to turn off, thereby completing the height adjustment of the top plate 316, improving the convenience of the device when used and the degree of automation of the device.
