Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a drilling equipment for geophysical prospecting. Background Technique

[0002] Geophysical prospecting, abbreviated as geophysical exploration, refers to the exploration of geological conditions such as formation lithology and geological structure by studying and observing the changes of various geophysical fields. Since different rock formation media that make up the earth's crust often have differences in density, elasticity, conductivity, magnetism, radioactivity, and thermal conductivity, these differences will cause local changes in the corresponding geophysical fields. The drilling method is often used to detect and study the physical properties of rocks, ores (or strata) and surrounding rocks. Therefore, a drilling device is required for drilling.

[0003] In this regard, it can be known from the retrieval of the novelty search agency that the patent with the publication number CN220580945U discloses a drilling equipment for geophysical prospecting, including a bottom plate and a drilling cone. On the top of the bottom plate, a box body is fixedly connected to the right side. A first motor is fixedly installed at the bottom of the inner cavity of the box body. The output end of the first motor is fixedly connected with a threaded rod. A threaded sleeve is threadedly connected to the surface of the threaded rod. One side of the threaded sleeve is fixedly connected with a connecting rod. One side of the connecting rod is fixedly connected with a bearing plate. A second motor is fixedly installed on the top of the bearing plate. It solves the problem that most of the existing drilling equipment is handheld. Because the device is extremely easy to vibrate during the working process, the force generated by the vibration will be transmitted to the user's arm, resulting in arm soreness, and thus greatly reducing the subsequent drilling efficiency, making it extremely inconvenient to use. The achieved technical effects are: high stability and high drilling efficiency.

[0004] The above-mentioned drilling equipment for geophysical prospecting disclosed in the technology uses a motor to drive the drilling cone to rotate and move down to perform the drilling work at the geophysical prospecting position, solving the problem that traditional handheld operation is prone to cause arm soreness during drilling. However, there are still the following deficiencies in use: 1. When the drilling cone drills the ground, it is inevitable that dust will be generated at the drilling position due to factors such as impact, and it is also easy for a large amount of soil impurities to adhere to the outside of the drilling cone after drilling. The dust is easy to harm the human body, and the environmental protection and cleanliness are not ideal; 2. During the drilling work, it is inevitable that the drilling cone will become hot. However, traditional direct external water spraying for cooling will change the soil properties at the drilling position, affecting the accuracy of geophysical prospecting work, and lacking a structure for safe cooling without changing the soil properties at the drilling position. In view of this, this application proposes a drilling equipment for geophysical prospecting to solve the above problems. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

The return seat 3 is slidably sleeved on the dust-proof and cleaning component. The dust-proof and cleaning component is used to automatically block and prevent dust from flying at the ground drilling position when the return seat 3 moves downwards, and is used to automatically brush and clean the outer side of the hollow drill rod 4 when the hollow drill rod 4 moves upwards and returns after drilling;

[0030] A water tank 8 is fixedly installed on the top of the return seat 3. Cooling water is filled in the water tank 8. An internal circulation water-cooling component is installed on the water tank 8. The hollow drill rod 4 is hermetically rotatably sleeved on the internal circulation water-cooling component. The water tank 8 is made of copper material. A plurality of heat dissipation fins 17 are fixedly connected to both sides of the water tank 8. A water supply pipe is fixedly connected and communicated to the right side of the top of the water tank 8. The internal circulation water-cooling component is used to extract the cooling water in the water tank 8, make it flow inside the hollow drill rod 4 and then return to the water tank 8, forming the effect of circulating and flowing inside the hollow drill rod 4 to absorb heat and cool down. In addition, because the water tank 8 is made of copper material, using the characteristic of good heat conduction of copper material, when the temperature of the cooling water is high after use, the heat can be effectively conducted to the heat dissipation fins 17 for heat dissipation and cooling, so as to continue to be used subsequently.

The support rod 14, dust cover 13, annular brush 12 and T-shaped guide rod 15 are arranged to cooperate with each other, and the supporting force on the T-shaped guide rod 15 will be relaxed when the circular seat 3 moves down. At this time, under the action of its own gravity, the dust cover 13 automatically moves down to cover the punching position on the ground, and performs the dust shielding and dust prevention work at the ground punching position. When the dust cover 13 moves down, it drives the T-shaped guide rod 15 to move down. When the subsequent circular seat 3 is raised to drive the hollow drill rod 4 to rise, the circular seat 3 is raised to a high position and squeezes the top inner wall of the T-shaped guide rod 15 to move it up. The T-shaped guide rod 15 drives the dust cover 13 to separate from the ground, and the shielding work is released. In addition, when the hollow drill rod 4 moves up, it will rub against the inner side of the annular brush 12, so as to achieve the effect of automatically brushing and cleaning the outer side of the hollow drill rod 4 when it is raised after use.

[0033] Further, the inner loop water-cooling component includes a circular seat 10 that is hermetically and rotatably sleeved inside the hollow drill rod 4. There are two sealing bearings fixedly sleeved inside the hollow drill rod 4, and the inner rings of the sealing bearings are fixedly sleeved on the outer side of the circular seat 10, achieving the effect of hermetically and rotatably installing the hollow drill rod 4 on the inner side. A water pump 9 is fixedly installed at the bottom of the water tank 8. The water inlet of the water pump 9 extends into the water tank 8, and a water supply pipe 16 located inside the hollow drill rod 4 is fixedly connected to the water outlet of the water pump 9. The circular seat 10 is fixedly sleeved on the water supply pipe 16. There is a sleeved hole at the top of the circular seat 10 that is fixedly connected to the outer side of the water supply pipe 16. A return water pipe 11 is fixedly installed by embedding at the right side of the bottom of the circular seat 10. There is an embedding hole at the bottom of the circular seat 10 that is fixedly connected to the outer side of the return water pipe 11. The top end of the return water pipe 11 extends into the water tank 8. There is a penetrating hole at the bottom of the water tank 8 that is fixedly connected to the outer side of the return water pipe 11. An avoidance hole is provided on the inner wall of the top of the return seat 3. The water pump 9 and the return water pipe 11 are both located in the avoidance hole and do not contact the inner wall of the avoidance hole; the circular seat 10, the water pump 9, the water supply pipe 16, and the return water pipe 11 are configured to cooperate. The water pump 9 pumps the cooling water in the water tank 8 and supplies it to the inside of the hollow drill rod 4 through the water supply pipe 16. As the water in the hollow drill rod 4 increases, the water is discharged back into the water tank 8 through the return water pipe 11 and is pumped and reused again, achieving the effect of the cooling water circulating and flowing inside the hollow drill rod 4 for heat absorption and cooling. And by using internal flow for heat absorption and cooling, the cooling water does not directly act on the geological soil and will not affect the external soil properties, and thus will not affect the subsequent geophysical exploration work.

[0034] Further, a storage battery is fixedly connected to the right side of the top of the U-shaped base 1. The electric slide rail 2, the drive motor 7, and the water pump 9 are all electrically connected to the storage battery. The provided storage battery is used to supply power to the electric slide rail 2, the drive motor 7, and the water pump 9. T-shaped anchor bolts 101 are provided on the front side and the rear side of the storage battery. Two threaded holes are provided on the right side of the top of the U-shaped base 1. The T-shaped anchor bolts 101 are threadedly sleeved in the corresponding threaded holes. The provided T-shaped anchor bolts 101 are used to drill into the ground for stable operation during use.

[0035] The usage method of this embodiment is as follows: Push this device to the ground at the geophysical exploration position where drilling is required. Rotate the T-shaped anchor bolts 101 so that they rotate downward and drill into the ground under the action of the corresponding threaded holes for stable operation. Start the drive motor 7 to drive the gear 6 to rotate. The gear 6 drives the outer gear ring 5 to rotate. The outer gear ring 5 drives the hollow drill rod 4 to rotate outside the circular seat 10. Start the electric slide rail 2 to drive the return seat 3 to move downward. The return seat 3 drives the hollow drill rod 4 to move downward. At this time, the rotating and downward-moving hollow drill rod 4 drills downward at the geophysical exploration position for drilling work;

[0036] When drilling, the water pump 9 is turned on, the water pump 9 extracts cooling water from the water tank 8, and supplies it to the hollow drill rod 4 through the water supply pipe 16. As the water in the hollow drill rod 4 increases, the water is discharged back to the water tank 8 through the return pipe 11 and is extracted and utilized again, so that the cooling water circulates in the hollow drill rod 4 to absorb heat and cool down. Moreover, the cooling water will not directly act on the geological soil, will not affect the external soil properties, and will not affect the subsequent geophysical exploration work, so as to achieve the effect of safely cooling the hollow drill rod 4 without changing the soil properties at the drilling position, thereby reducing the risk of high-temperature damage.

[0037] The T-shaped guide rod 15 drives the dust cover 13 to separate from the ground, and the shielding work is released by automatically shielding the punching position to prevent dust during drilling and automatically brushing the outer side of the hollow drill rod 4 after use, which effectively reduces the phenomenon of generating a large amount of dust that harms the health of personnel and improves the environmental protection and cleanliness of use.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
