Description

Technical Field

[0001] The patent of this invention belongs to the field of geological exploration technology, and specifically relates to a drilling device for hydrogeological exploration. Background Art

[0002] Hydrogeology refers to various changes and movement phenomena of groundwater in nature, such as the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, so as to make rational use of groundwater. Hydrogeological detection helps researchers understand the geological conditions. At present, when researchers conduct hydrogeological detection, they usually drill to extract soil samples from a certain depth from the ground for hydrogeological detection.

[0003] According to the inventor's inquiry, the prior art, such as Chinese patent (CN115112416A), discloses a hydrogeological condition detector for mines, including a bracket, a sampling mechanism, an adjustment mechanism, a driving mechanism and a clamping mechanism. The sampling mechanism includes a sampling tube, a first-level sampling box, a second-level sampling box and a third-level sampling box. The adjustment mechanism includes a first connecting rod, a first screw rod, a second screw rod, a first partition, a second partition, a first cam, a second cam, a third cam, three second connecting rods and a synchronization rod. The driving mechanism drives the sampling tube to rotate. The clamping mechanism is used to limit the up and down movement of the sampling tube. Although the device can sample in layers, it has the following defects: 1. The length of the drill rod in the device is limited. Each drill rod can only be used for underground sampling at a corresponding depth, and the loading and unloading is cumbersome. At the same time, the drill bit of the device is not set reasonably, and its smooth drill bit surface makes it difficult to drill into the deep formation for sampling; 2. Although the sampling structure of the device can perform layered sampling at the same time, the spacing between the sampling boxes is limited by the length of the sampling rod body, and the layered sampling is not very meaningful. In addition, the design of multiple sampling ports will weaken the compression resistance of the sampling rod body structure. In the high-pressure environment underground, the service life is shortened and the use cost is increased; 3. The device cannot directly explore the underground environment. It is difficult to accurately explore the hydrogeological conditions deep underground using only the samples obtained from the sampling mechanism.

[0004] Therefore, this paper proposes a drilling device for hydrogeological exploration. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. Example 1

[0021] like Figure 1 As shown, the prior art in this embodiment has the following problems: the inventor found that in practice, when the water level is buried deep, the method has the following disadvantages: when the groundwater is buried deep, the length of the wire is long, and the wire put into the hole is very heavy, which often makes it bulky and time-consuming and laborious to operate manually with both hands due to the heavy weight of the wire; when the wire is too long, the collision of the wire end is easy to cause misjudgment; at the same time, it is not easy to adjust when recovering and straightening the wire, and the recovery amount cannot be accurately controlled; the traditional "multimeter" method requires multiple factors to complete the work together and none of them can be missing, and there are many external factors that can interfere with the measurement; therefore, the inventor provides a drilling device for hydrogeological exploration, including a base, a detachable bracket, a measuring A component, a detachable bracket is installed on the base, and a measuring component is installed on the detachable bracket. The upper part of the detachable bracket is arranged in a stable right-angled triangle shape, and a bracket hanging hole 7 is arranged at the tip of the detachable bracket near the hole 6; the measuring component also includes a gravity measuring device 31, a winding drum 32 that can be positioned with an emergency stop, a load-bearing PE line 11, and a buoy body. The gravity measuring device 31 is installed on the hanging hole 7 through the hook 8 above it, and the winding drum 32 that can be positioned with an emergency stop is installed on the hook 8 below the gravity measuring device 31 through the hanging buckle 9 thereon, the upper end of the load-bearing PE line 11 is connected to the turntable shaft 13 of the winding drum, and the end of the load-bearing PE line 11 is connected to the buoy body; The device has a simple structure and is easy to operate and carry. The operating principle of the device is simple. The water level can be measured by controlling the winding disk 32 that can be stopped and positioned in an emergency, thereby reducing the difficulty of traditional groundwater measurement work. The load-bearing PE line 11 is controlled by the ratchet 21 mechanism in the emergency stop positioning device to straighten it, thereby improving the measurement accuracy. The device adopts the physical gravity principle to measure groundwater, the measurement process is less affected by external interference, and the measurement result is highly reliable. Example 2

[0022] like Figure 1 As shown, derived from the above embodiments, the base provided in this embodiment also includes a base 1 and a counterweight 2. The base 1 is horizontally placed next to the hole 6, and the counterweight 2 is placed on the upper surface of the base 1. A detachable bracket that can support the measuring component is installed on the side of the base 1 close to the hole 6 through a bolt hole structure 30; the setting of the counterweight 2 in the device can increase the overall stability of the device, and if the weight of the load-bearing PE line 11 is too large due to the hole being too deep, the counterweight 2 can be appropriately increased or decreased according to the weight of the load-bearing PE line 11 to make it stable. Example 3

[0023] like Figure 1As shown, derived from the above embodiments, the detachable bracket provided in this embodiment also includes a shaft rod 3, an upper bracket 4, and a lower bracket 5. The upper bracket 4 is installed on the side of the top end of the shaft rod 3 close to the hole 6 through a bolt hole structure 30. The lower bracket 5 connects the shaft rod 3 and the rear end of the upper bracket 4 and forms a right-angled triangle shape with the two. A hanging hole 7 is provided on the end of the upper bracket 4. The device adopts a right-angled triangle-shaped bracket as the supporting structure of the measuring component, wherein the right-angled triangle-shaped bracket can increase the stability of its structure and prevent the shaking of the bracket from affecting the measurement result. Example 4

[0024] like Figure 1 As shown, derived from the above embodiments, the gravity measuring device 31 provided in this embodiment is configured as an electronic scale 10 with a hook; before use, the fixed mass of the winding drum and the buoy body on the electronic scale can be set as M1, and then the buoy body can be lowered. When encountering groundwater, the buoy 28 will float on the water. At this time, the electronic scale reading is M2. After debugging, M2 is approximately 70g smaller than M1; and at this time, the winding drum is positioned by the emergency stop positioning device, stops rotating, and the buoy body no longer falls. The device provides timely feedback, thereby avoiding the increased measurement difficulty due to more external interference measurement factors when using the "multimeter" method. Example 5

[0025] like Figures 2 to 8As shown, derived from the above embodiments, the winding reel 32 capable of emergency stop positioning provided in this embodiment also includes a winding turntable 12, a turntable shaft 13, a rotating wheel 14, a ball 15, a groove body 16, a wheel axle 17, a handle 18, a hook 9, a rotating handle 19, a butterfly bolt 20, and an emergency stop positioning device. The winding turntable 12 is installed on the wheel axle 17 through the turntable shaft 13, and the rotating wheel 14 is provided with an axle 17. The ball 15 is rotatably installed in the groove body 16 between the winding turntable 12 and the front wheel of the rotating wheel 14. The handle 18 and the hook 9 are provided on the end surface of the front wheel of the rotating wheel 14. An emergency stop positioning device is installed between the winding turntable 12 and the rear wheel of the rotating wheel 14. A butterfly bolt 20 is installed on the rear end of the turntable shaft 13, and a rotating handle 19 is provided on the rear end of the turntable shaft 13. When in use, the emergency stop positioning device on the winding reel can be opened to allow the thin rod-shaped buoy body to enter the hole by the action of its own weight, and the handle 1 8, by adjusting the tightness of the butterfly bolt 20, the friction between the contact surface of the turntable shaft 13 and the wheel axle 17 is controlled, thereby controlling the rotation speed of the winding turntable 12, and then controlling the thin rod-shaped buoy body to freely and uniformly enter the hole. When encountering groundwater, the buoy 28 will float on the water and the winding drum will not rotate without the weight of the buoy body. Then close the emergency stop positioning device, and then while holding the handle 18 steadily, control the ratchet 21 mechanism in the emergency stop positioning device by turning the handle 19 to accurately adjust the recovery amount of the bent part of the load-bearing PE line 11, thereby straightening the load-bearing PE line 11. During the straightening and recovery process, if the value of the weight measuring device begins to increase, the emergency stop positioning device can be opened again, and while holding the handle 18 steadily, the handle 19 can be turned slightly to restore the value to its original state. Finally, the emergency stop positioning device is closed. At this time, the load-bearing PE line 11 is straightened, and the data measured in this way is more accurate.

[0026] Among them, the above-mentioned emergency stop positioning device also includes a ratchet 21, an inner cavity 22, a positioning card 23, a spring 24, a tail handle 25, and a positioning piece 26. The ratchet 21 is arranged on the rear wheel of the rotating wheel 14, and an inner cavity 22 is arranged in the winding turntable 12 above the ratchet 21. The positioning card 23, the spring 24, the tail handle 25, and the positioning piece 26 are installed in the inner cavity 22. The positioning card 23 is connected to the wall of the inner cavity 22 of the winding turntable 12 through the spring 24. The rear end of the positioning card 23 is rotatably installed with the tail handle 25. The tail handle 25 and the wall of the inner cavity 22 are provided with a positioning piece 26 that can be correspondingly locked. The rear end of the tail handle 25 extends out of the winding turntable 12; When the emergency stop positioning device is to be opened, the tail handle 25 can be lifted and then rotated to clamp the positioning piece 26 on the tail handle 25 onto the positioning piece 26 in the wall of the inner cavity 22, so that the positioning card 23 can be separated from the ratchet 21, thereby facilitating the rotation of the winding turntable 12; similarly, when the emergency stop position needs to be closed, the tail handle 25 can be rotated to make the positioning card 23 clamped into the card slot of the ratchet 21 under the action of the elastic force of the spring 24, thereby preventing the winding turntable 12 from rotating forward when the line is reversed and wound back; the device has a simple structure and is easy to operate and carry, wherein the shaking of the winding turntable 12 can be avoided by stably holding the handle 18 during operation. Example 6

[0027] like Figure 1 As shown, derived from the above embodiments, the load-bearing PE line 11 provided in this embodiment is detachably installed with a positioning device 33 at a position parallel to the hole mouth; the load-bearing PE line 11 can adopt 0.5mm braided Dainippon line, which is strong and durable, and the positioning device can adopt a pin. When the buoy body stops falling, the pin can be nailed on the load-bearing PE line 11 at the hole mouth to record the position. Example 7

[0028] like Figure 1 As shown, derived from the above embodiment, the buoy body provided in this embodiment also includes a lifting eye screw 27, a buoy 28, and a metal cone head 29. The buoy 28 and the metal cone head 29 are connected by the lifting eye screw 27, and the top lifting eye of the lifting eye screw 27 is connected to the load-bearing PE line 11.

[0029] The working principle of the present invention is: before use, the fixed mass of the winding drum and the buoy body on the electronic scale can be set as M1. When in use, the emergency stop positioning device on the winding drum can be opened to allow the thin rod-shaped buoy body to enter the hole through the action of its own weight. The friction between the turntable and the wheel axle 17 can be controlled by adjusting the tightness of the butterfly bolt 20 on the winding drum, so that the thin rod-shaped buoy body can be controlled to enter the hole freely and at a uniform speed. When encountering groundwater, the buoy 28 will float on the water surface 34 and the winding drum will not rotate without the weight of the buoy body, and then the emergency stop positioning device can be closed. , and then the recovery amount of the bent part of the load-bearing PE line 11 is accurately adjusted through the ratchet 21 mechanism in the emergency stop positioning device. At this time, the electronic scale reading is M2. After debugging, M2 is about 70g smaller than M1. At this time, the winding reel is positioned by the emergency stop positioning device, stops rotating, and the buoy body no longer falls. Then, a pin is nailed at the hole mouth to record the position, and finally the buoy body and connecting wire below are lifted up through a turntable or manually, and the length of the connecting wire below the pin is measured to measure the depth of the water level in the hole. Because the connecting wire is very thin, it can be folded several times during actual operation for more convenient measurement.
