Description

A drilling device for water conservancy and hydropower exploration Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower technology, and in particular to a drilling device for water conservancy and hydropower exploration. Background Technology

[0002] Drilling operations are frequently involved in the surveying and exploration of water conservancy and hydropower projects. Changing drill bits during drilling operations presents numerous inconveniences. Traditional drilling equipment often uses threaded connections to fix the drill bit to the drill pipe. This method has the following drawbacks: in complex field environments, such as damp, muddy, or saline-alkali land, the threaded parts are prone to corrosion or blockage, making manual disassembly and installation very difficult. Therefore, changing drill pipes often requires the use of specialized tools such as wrenches for tightening operations. However, using tools is cumbersome and demands a high level of physical strength and experience from the operators.

[0003] Therefore, there is an urgent need to provide a drilling device for water conservancy and hydropower exploration that can enable tool-free and rapid assembly and disassembly of drilling pipes, avoiding the risk of thread jamming, while also possessing good stability and environmental adaptability, so as to improve the efficiency, safety and convenience of drilling equipment in field operations. Summary of the Invention

The locking element is used to lock the toggle block. The end of the drilling pipe is provided with a fixed groove that can be inserted and engaged with the reinforcing block.

[0013] In some embodiments, the locking element includes a second circular block and a pin. The outer wall of the rotating column is fitted with the second circular block, which is located between the actuating block and the first motor. The second circular block has a through hole, and the pin is slidably connected in the through hole. The actuating block has a fitting groove that can engage with the pin.

[0014] In some embodiments, the end of the drill pipe away from the first motor is detachably connected to an extension section via the replacement assembly.

[0015] In some embodiments, the lifting assembly includes a vertical plate, a second motor, a lead screw, an auxiliary rod, a scale, and a guide. The top of the base is provided with vertical plates located on both sides of the drill hole. The two vertical plates are installed vertically and each has a movable groove inside. A lead screw is rotatably installed in the movable groove of one vertical plate. A second motor is installed on the top of the vertical plate, and the output end of the second motor is connected to the end of the lead screw. An auxiliary rod is provided in the movable groove of the other vertical plate. A support plate for installing the first motor is provided between the two vertical plates. One end of the support plate is threadedly connected to the lead screw, and the other end of the support plate is slidably connected to the auxiliary rod. A scale that can indicate the height position of the support plate is embedded in the inner wall of the vertical plate with the auxiliary rod. The top of the base is also provided with a guide, which is connected to the side wall of the support plate. The guide is used to provide guidance when the support plate moves vertically.

[0016] In some embodiments, the guide includes positioning posts and support rods. The top of the base is provided with a pair of vertically arranged positioning posts, and support rods are slidably sleeved on the positioning posts respectively. The ends of the support rods away from the positioning posts are connected to the sidewalls of the support plate.

[0017] In some embodiments, a cleaning assembly is also included, comprising a water storage tank, a cap, a water pump, a first water supply pipe, a second water supply pipe, and a cleaning nozzle. The top of the base is provided with a water storage tank and a water pump capable of storing water. The top of the water storage tank is provided with a water inlet, and a cap is installed at the water inlet. One end of the water pump is connected to the water storage tank via the first water supply pipe, and the other end of the water pump is connected to the cleaning nozzle via the second water supply pipe. A position plate is installed on the lifting assembly, and part of the second water supply pipe is embedded inside the position plate.

[0018] In some embodiments, the control component includes a control box, and the first motor and the lifting component are both communicatively connected to the control box. The control box is provided with control buttons that can respectively operate the first motor and the lifting component.

[0019] In some embodiments, the base has a storage box on top, the storage box has a chamber inside that can store items, and a closing plate is movably connected to the top of the storage box.

[0020] In some embodiments, the base is provided with a plurality of casters and fixing pins at its bottom.

[0021] The beneficial effects of this utility model are:

[0022] 1. By replacing components, a detachable connection between the first motor and the drill pipe is achieved. The plug-in connection allows for tool-less, quick replacement of the drill pipe, improving adaptability and ease of operation in the field. Furthermore, the non-threaded connection reduces the failure rate caused by corrosion in the field environment and lowers the risk of thread jamming due to rust. Simultaneously, the replacement components allow for locking of the connection between the first motor and the drill pipe, enhancing the overall stability and safety of the drilling equipment.

[0023] 2. The replacement component in this application adopts a plug-in structure. The reinforcing block and the fixing groove at the end of the drill pipe are plugged in. By inserting the reinforcing block into the fixing groove, and then rotating the actuating block, the moving block is driven to rotate. Under the guidance of the arc-shaped groove, the moving block causes the locking part of the reinforcing block to enter or exit the fixing groove. Thus, the operator can complete the installation and removal of the drill pipe without using a wrench or special tools. At the same time, a pin-type locking mechanism is adopted. The pin on the second round block is inserted into the fitting groove on the actuating block to prevent the actuating block from rotating back, thereby locking the rotating block, improving the connection reliability and reducing the connection loosening caused by vibration and other factors.

[0035] "First," "second," etc. As used in this article, these terms serve as labels for the nouns preceding them and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). Detailed Implementation

[0036] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0037] Referring to Figures 1 to 7, this embodiment is a drilling device for water conservancy and hydropower exploration, including a base 1, a first motor 201, a replacement component 2, a lifting component 5, and a control component. A drilling port is provided through the middle of the base 1. The lifting component 5 and the control component are located on the top of the base 1. The output end of the lifting component 5 is connected to a support platform, which is located above the drilling port. The first motor 201 is located on the support platform. The output end of the first motor 201 is connected to a drilling pipe 208 facing the drilling port via the replacement component 2. The replacement component 2 can lock the connection between the first motor 201 and the drilling pipe 208. The first motor 201 drives the drilling pipe 208 to perform drilling operations. The lifting component 5 drives the support platform to move vertically to adjust the drilling depth of the drilling pipe 208. The first motor 201 and the lifting component 5 are both communicatively connected to the control component, which controls the opening and closing of the first motor 201 and the lifting component 5.

[0038] In some implementations, as shown in Figures 2 and 3, the replacement component 2 includes a rotating column 202, a first circular block 203, a rotating block 204, a moving block 206, a reinforcing block 207, a toggle block 212, and a locking element. The output end of the first motor 201 is fixedly connected to the rotating column 202, and the end of the rotating column 202 away from the first motor 201 is fixedly connected to the first circular block 203. The rotating block 204 is rotatably embedded in the first circular block 203 facing the wall of the first motor 201. The top of the rotating block 204 is fixedly connected to the toggle block 212, which is rotatably sleeved on the outer wall of the rotating column 202. An arc-shaped groove 205 is formed on the rotating block 204, and the moving block 206 is slidably embedded in the arc-shaped groove 205. The arc-shaped groove 205 can guide the movement of the moving block 206. The bottom of the first circular block 203 is provided with a movable groove 213, which corresponds to and is connected through the arc-shaped groove 205. The two side walls of the arc-shaped groove 205 are inclined to engage the movable block 206, so that the movable block 206 will not fall out of the movable groove 213. The bottom of the movable block 206 is connected to a reinforcing block 207 that can be slidably connected in the movable groove 213. The end of the reinforcing block 207 facing the drill pipe 208 is provided with a protruding engaging part. A locking member is fixedly sleeved on the rotating column 202. The locking member is used to lock the actuating block 212 to limit the rotation of the movable block 206 driven by the actuating block 212. The end of the drill pipe 208 is provided with a fixing groove 209 that can be inserted and engaged with the reinforcing block 207. The interior of the fixing groove 209 is L-shaped, which allows the engaging part at the end of the reinforcing block 207 to slide appropriately.

[0039] Furthermore, the rotating block 204 is provided with a pair of arc-shaped grooves 205, and the bottom of the first circular block 203 is provided with a movable groove 213 corresponding to and communicating with the arc-shaped grooves 205. The arc-shaped guide directions of the pair of arc-shaped grooves 205 are roughly opposite, and movable blocks 206 are slidably embedded in each arc-shaped groove 205. The bottom of each movable block 206 is correspondingly connected to a reinforcing block 207. The end of the drill pipe 208 is provided with a pair of fixed grooves 209 corresponding to the reinforcing blocks 207. By rotating the actuating block 212, the actuating block 212 drives the rotating block 204 to rotate in the first circular block 203. Guided by the arc-shaped grooves 205, the pair of reinforcing blocks can synchronously expand outward or contract inward to engage with or disengage from the fixed grooves 209.

[0040] Furthermore, the locking element includes a second circular block 210 and a pin 211. The second circular block 210 is sleeved on the outer wall of the rotating column 202. The second circular block 210 is located between the actuating block 212 and the first motor 201. The second circular block 210 has a through hole, and the pin 211 is slidably connected in the through hole. The actuating block 212 has a fitting groove 214 that can be inserted and engaged with the pin 211. Specifically, in this embodiment, the pin 211 and the fitting groove 214 can also be replaced by other connection methods such as bolts.

[0041] As shown in Figure 4, by starting the first motor 201, the output end of the first motor 201 drives the first circular block 203 and the drill pipe 208 to rotate and drill. When it is necessary to replace or install the drill pipe 208, the drill pipe 208 is raised to a specified height by the lifting component 5. The operator inserts the reinforcing block 207 axially into the fixing groove 209, and then manually rotates the actuating block 212, causing the actuating block 212 to drive the rotating block 204 to rotate. When the rotating block 204 rotates, due to the combined action of the side wall of the reinforcing block 207 being abutted by the side wall of the fixing groove 209, the arc-shaped groove 205 inside it pushes the moving block 206 to move outward along the arc-shaped path, thereby driving the reinforcing block 207 to move in the moving groove 213 of the first circular block 203. The moving block 206 simultaneously drives the reinforcing block 207 to expand outward, and the snap-fit ​​part of the reinforcing block 207 snaps into the interior of the fixing groove 209, realizing the initial fixation of the drill pipe 208. Finally, the insertion pin 211 passes through the second round block 210 and into the fitting groove 214 of the actuating block 212, thereby restricting the rotation of the rotating block 204 and ensuring the stability of the entire structure, so that the operator can complete the installation and removal of the drill pipe 208 without using a wrench or special tools.

[0042] Furthermore, as shown in Figure 3, the end of the drill pipe 208 away from the first motor 201 is detachably connected to an extension section 215 via a replacement component 2.

[0043] By replacing component 2, multiple extension sections 215 can be detachably connected. By repeating the assembly steps of replacing component 2 to connect extension sections 215, the drilling depth can be increased.

[0044] In some implementations, as shown in Figures 1 and 6, the lifting assembly 5 includes a vertical plate 501, a second motor 503, a lead screw 504, an auxiliary rod 505, a scale 506, and a guide. The top of the base 1 is provided with vertical plates 501 located on both sides of the drill hole. The two vertical plates 501 are installed vertically and each has a movable groove 502 inside. The lead screw 504 is rotatably installed in the movable groove 502 of one vertical plate 501. The second motor 503 is installed on the top of the vertical plate 501. The output end of the second motor 503 passes through the vertical plate 501 and is connected to the end of the lead screw 504. The auxiliary rod 505 is installed in the movable groove 502 of the other vertical plate 501 along the axis. A support plate 507 for mounting the first motor 201 is provided between the two vertical plates 501. One end of the support plate 507 is threadedly connected to the lead screw 504, and the other end is slidably connected to the auxiliary rod 505, so that the support plate 507 forms a support platform for the first motor 201 and the drill pipe 208. A scale 506 is embedded in the inner wall of the vertical plate 501 with the auxiliary rod 505 to indicate the height position of the support plate 507, so that the operator can easily understand the depth of the support plate 507. A guide is also provided at the top of the base 1. The guide is connected to the side wall of the support plate 507 and provides guidance when the support plate 507 moves vertically.

[0045] Furthermore, the guide includes positioning posts 509 and support rods 508. The top of the base 1 is provided with a pair of vertically arranged positioning posts 509, and support rods 508 are slidably sleeved on the positioning posts 509 respectively. The ends of the support rods 508 away from the positioning posts 509 are connected to the side wall of the support plate 507.

[0046] The positioning post 509 provides a fixed sliding track for the support. When the support plate 507 needs to move up and down, the support rod 508 provides an auxiliary guiding function, so that the support plate 507 can move in a precise straight line along the direction of the positioning post 509, reducing the offset and tilt caused by lateral force.

[0047] Furthermore, in this embodiment, a double-layer sealing structure (not shown in the figure) is adopted at the threaded connection between the lead screw 504 and the support plate 507. The inner layer is a fluororubber O-ring, which can prevent the intrusion of mud, sand, and moisture; the outer layer is equipped with a detachable protective cover with a labyrinth design, combined with a self-lubricating polytetrafluoroethylene retaining ring, which forms multiple physical barriers while ensuring the free rotation of the lead screw. This structure has passed the IP67 protection level test and can effectively resist harsh environments such as high dust and rain immersion. The auxiliary rod 505 and the support rod 508 adopt a hollow cavity design with a built-in compressed air blowing system. When the equipment starts or stops, the system automatically sprays high-pressure gas into the guide groove to remove the deposited mud and sand particles. At the same time, a scraper is set at the sliding connection, which can actively scrape off the attached foreign objects during the movement of the support plate 507, avoiding the risk of jamming from the source.

[0048] In this embodiment, the lead screw 504 serves as the core load-bearing component. Its threaded connection with the support plate 507 is not a single-point load-bearing point, but rather forms a linearly distributed bearing surface along the axial direction through the threaded pair. According to the principles of material mechanics, with reasonable design of lead and pitch parameters, the vertical load can be evenly distributed. The auxiliary rod 505 and the support rod 508 are slidably connected. Through the cooperation of a precision guide groove and a linear bearing, a rigid constraint can be formed in the horizontal direction to counteract the lateral force generated during drilling operations, forming a three-dimensional load-bearing system of "axial load + lateral constraint." The three-end sliding connection essentially constitutes a statically indeterminate structure. Although not completely fixed, through the reasonable arrangement of constraint conditions, each guide component can collaboratively share the bending moment. For example, when the drill pipe 208 generates torque through eccentric operation, the constraint reaction force of the auxiliary rod 505 and the support rod 508 can form a force couple balance with the lead screw 504, effectively reducing the overload risk of the lead screw 504. According to finite element analysis data, the maximum stress of this structure under full load is only 40% of the allowable stress of the material, possessing significant safety redundancy.

[0049] In some embodiments, as shown in Figures 1 and 5, the drilling apparatus further includes a cleaning assembly, which includes a water tank 8, a cap 9, a water pump 11, a first water supply pipe 10, a second water supply pipe 12, and a cleaning nozzle 14. The top of the base 1 is equipped with a water tank 8 and a water pump 11 capable of storing water. The top of the water tank 8 has a water inlet, and a cap 9 is installed at the water inlet. One end of the water pump 11 is connected to the water tank 8 via the first water supply pipe 10, and the other end of the water pump 11 is connected to the cleaning nozzle 14 via the second water supply pipe 12. A horizontally arranged position plate 13 is installed between the side walls of a pair of vertical plates 501. The second water supply pipe 12 is partially embedded inside the position plate 13, and the cleaning nozzle 14 protrudes from the outer wall of the position plate 13 and corresponds to the drilling pipe 208.

[0050] First, open the cap 9 on the water storage tank 8 and fill the water storage tank 8 with water through the water inlet. Then start the water pump 11. The water pump 11 draws water from the water storage tank 8 through the first water supply pipe 10 and then delivers it to the cleaning nozzle 14 through the second water supply pipe 12. The cleaning nozzle 14 can clean the drilling pipe 208 within the spray range.

[0051] In some implementations, as shown in Figure 1, the control component includes a control box 3. The first motor 201, the second motor 503, and the water pump 11 are all communicatively connected to the control box 3. The control box 3 is equipped with control buttons 4 that can respectively control the first motor 201, the second motor 503, and the water pump 11 to start and stop.

[0052] In some embodiments, as shown in FIG5, the top of the base 1 is provided with a storage box 15 located adjacent to the water tank 8. The storage box 15 has a chamber inside that can store items, and a closing plate 16 is movably connected to the top of the storage box 15.

[0053] In some implementation schemes, as shown in Figures 1, 5, and 7, the bottom of the base 1 is provided with multiple casters 7 and fixing pins 6. Specifically, in this embodiment, the fixing pins 6 can be selected in appropriate length and shape according to different actual working environments, such as grass, mud, concrete, etc., to ensure optimal grip.

[0054] The casters 7 are mounted on the bottom of the base 1, allowing the entire drilling rig to be easily moved around the work site. For exploration tasks that require frequent changes in work location, this effectively saves manpower and time costs, and also improves the equipment's mobility in complex terrain or confined spaces.

[0055] Once the drilling rig reaches the designated working position, to prevent displacement due to vibration or external forces during drilling, the base 1 can be securely fixed to the ground using fixing nails 6. This ensures accuracy and safety during the drilling process.

[0056] The implementation principle of a drilling device for water conservancy and hydropower exploration is as follows:

[0057] Traditional threaded connections require manual unscrewing of the drill bit and drill rod for disassembly and installation, a process that is not only time-consuming and labor-intensive but also prone to jamming in complex environments. Therefore, this technical solution adopts a non-threaded connection method, using plug-in replacement component 2, which can be operated without tools.

[0058] The control button 4 on the control box 3 controls the first motor 201, the second motor 503 and the water pump 11 respectively. The first motor 201 is started to drive the first circular block 203 and the drilling pipe 208 to perform rotary drilling.

[0059] When the drill pipe 208 needs to be replaced, the second motor 503 is controlled to drive the lead screw 504 to rotate. Since one end of the support plate 507 is threadedly connected to the lead screw 504, and the other end of the support plate 507 is slidably connected to the auxiliary rod 505, the support plate 507 can move upward. The support plate 507 will drive the support rod 508 to move synchronously. With the help of the sliding cooperation between the support rod 508 and the positioning column 509, the movement of the support plate 507 is provided with a certain support and guidance, ensuring the stability of the support plate 507 during the movement. The specific height position of the support plate 507 is determined according to the scale 506 on the inner wall of the vertical plate 501.

[0060] The operator only needs to insert the reinforcing block 207 into the corresponding fixing groove 209, and then rotate the actuating block 212. The rotating block 204 drives the moving block 206 to move through the arc groove 205 inside the rotating block 204, so that the reinforcing block 207 can engage or disengage from the fixing groove 209 on the drilling pipe 208, thereby completing the fixing or release of the drilling pipe 208.

[0061] To further ensure the stability of the drill pipe 208, after the above-mentioned fixing process is completed, the movable block 206 is rotated and locked by the cooperation of the pin 211 and the fitting groove 214. After the reinforcing block 207 fixes the drill pipe 208, the pin 211 is inserted through the through hole of the second round block 210 into the fitting groove 214 in the actuating block 212. This prevents the movable block 206 from rotating due to accidents, thus preventing the reinforcing block 207 from loosening from the fixing groove 209, and enhancing the stability and safety of the entire connection.

[0062] Compared to the traditional method of using specific tools for screwing, this technical solution simplifies the operation steps by manually rotating the actuating block 212, which generates a corresponding mechanical linkage. This reduces the physical and technical requirements for operators, enabling the replacement of the drill pipe 208 to be completed efficiently even in complex field environments.

[0063] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
