Description

Technical Field

[0001] The present application relates to the field of water conservancy engineering technology, and in particular to underwater topographic survey equipment. Background Art

[0002] The complex hydrogeological conditions of underground rivers make them prone to karst seepage after reservoir construction. Severe seepage could affect the functioning of hydropower stations. Underground rivers, which flow below the surface, are a type of underground karst landform. These rivers are formed by the accumulation of groundwater, or by surface water seeping through cracks in underground rocks, through rock erosion, collapse, and water transport.

[0003] Due to the difficulty of surveying underground rivers, the propulsion systems of existing underwater exploration equipment are blocked when passing through rock, soil, gravel and water layers, and the propeller blades are easily blocked by the gravel. Existing underwater exploration equipment also lacks the necessary support for drilling holes, and cannot proceed when encountering narrow caves. Surveying in the crisscrossing network of caves is extremely difficult. Summary of the Invention

The reaming drill frame is fixedly sleeved on the surface of the vortex fan frame, the reaming drill frame faces the surface of the vortex cover, the drilling wall positioning wheel is evenly rotatably connected to the reaming drill frame, and the The drill surface positioning wheel rotates evenly and is connected to the reaming drill frame, the reaming drill tool is evenly arranged on the reaming drill frame, the digging drill tool is evenly arranged on the vortex fan frame, and the balanced survey assembly includes an annular propeller, an axial propeller, an anti-collision guide vane, a waste slag guide vane and a surveyor. The annular propeller is evenly buried on the circumference of the vortex cover, the axial propeller is evenly buried on the circumference of the vortex cover, the anti-collision guide vane is evenly arranged between the survey cabin and the vortex cover, the vortex fan frame faces the anti-collision guide vane, the waste slag guide vane is evenly arranged between the power cabin and the vortex cover, the anti-collision guide vane faces the waste slag guide vane, and the surveyor is arranged at one end of the power cabin.

[0008] In one embodiment of the present application, a gear shaping platform is provided at one end of the survey top shaft, and the gear shaping platform is inserted into the vortex fan frame. A positioning top is provided at one end of the vortex fan frame, and the end face of the vortex fan frame is tilted and retracted from the end face of the reaming drill frame and the survey top shaft.

[0009] In one embodiment of the present application, drill wall positioning cabins are evenly embedded on the reaming drill rack, the drill wall positioning wheels are rotatably connected to the drill wall positioning cabins, the rotation profile of the drill wall positioning wheels is higher than the rotation profile of the reaming drill tool, and drill surface positioning cabins are evenly embedded on the reaming drill rack, the drill surface positioning wheels are rotatably connected to the drill surface positioning cabins, and the rotation profile of the drill surface positioning wheels is higher than the drill surface positioning wheels.

[0010] In one embodiment of the present application, a propulsion cabin is buried around the vortex cover, a suspension frame is provided in the propulsion cabin, the circumferential propeller and the axial propeller are both provided on the suspension frame, the circumferential propeller faces the survey top shaft, and the axial propeller faces the side wall of the propulsion cabin.

[0011] In one embodiment of the present application, a tail shroud is provided at one end of the power cabin, and the tail shroud gradually reduces the diameter of the power cabin outline. A sealing flange is provided at one end of the tail shroud, and the surveyor is provided on the sealing flange.

[0012] In one embodiment of the present application, an overhanging ring support is provided at one end of the reaming drill frame, and the overhanging ring support is flush with the vortex cover. A jet cover is provided at one end of the vortex cover, and the jet cover faces the tail cover.

[0013] The beneficial effects of the present application are as follows: the underwater topographic survey equipment obtained by the present application through the above-mentioned design, when in use, the survey device realizes the movement and direction change of the survey device underwater through the combined action of the radial thrust of the annular propeller and the axial thrust of the axial propeller, and collects the reservoir area data through the surveyor and transmits it to the remote terminal. When the survey device encounters a narrow area between caves and is unable to move forward, the annular propeller and the axial propeller push the front of the reaming drill frame to face the drilling surface of the rock wall, the top end of the vortex fan frame is aligned with the rock wall, the rotation speed of the vortex fan frame is controlled by the vortex motor, and under the thrust of the vortex, the drill surface positioning wheel first contacts the rock wall for cutting and positioning, cooperates with the drilling centering of the top end, and repeatedly uses the annular propeller and the axial propeller to correct the drilling error. The eddy current motor increases the rotational speed of the vortex fan frame, while the reaming and digging drills drill the rock wall. Because the end face of the vortex fan frame tilts and retracts from the reaming drill frame and the survey jack, the rock wall wrapped by the vortex fan frame forms a cone, which cooperates with the top and drill face positioning wheels to cut and position the borehole. Maintaining continuous propulsion of the eddy current motor, the reaming drill drills and expands the inner wall of the borehole, while the drill wall positioning wheels cut and position the inner wall of the borehole. This adapts to changes in the borehole's structural and compositional properties caused by changes, thereby increasing the stability of underwater terrain drilling. Without the need for wall support, the suspending cave can be used to drill through narrow rock walls, enabling the survey of crisscrossing caves and making underwater terrain surveys more convenient.

[0014] Compared with traditional manipulator drilling, the overall fluid design of the survey device, the reaming drill frame is flush with the vortex cover, reducing the interference of the inner wall of the borehole on the movement of the survey device. Through the streamline design of the outer wall of the survey cabin, the outer wall of the power cabin and the inner wall of the vortex cover, combined with the guidance of the fluid by the anti-collision guide vanes and the waste guide vanes, and through the bunching effect of the vortex, the drilling thrust direction of the survey device is more concentrated and the drilling stability is higher. The contour diameter of the tail of the power cabin gradually decreases to reduce the impact and damage of the drilling waste fluid on the tail surveyor. Compared with the traditional manipulator drilling waste handling, there is no need for related settings. The waste fluid is guided by the tail of the vortex cover, and the ejected waste fluid is concentrated and sprayed outward, reducing blockage in the borehole and facilitating the overall fluid design of the survey device. The buried annular and axial thrusters reduce interference with the borehole inner wall during drilling. Combined with the water absorption effect of the vortex fan, waste residue from the reaming and digging drill tools is sucked into the vortex cover, reducing the risk of waste debris and debris clogging the propeller blades. This ensures high stability of the surveying device's propulsion system and reduces propulsion interference resistance. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] Example

[0026] like Figures 1-6 As shown, the underwater terrain survey equipment according to an embodiment of the present application includes an eddy current survey assembly 100, a drilling assembly 300, and a balanced survey assembly 500. The drilling assembly 300 is installed at one end of the eddy current survey assembly 100, and the balanced survey assembly 500 is installed on the sides of the eddy current survey assembly 100. The eddy current survey assembly 100 provides eddy current power to drill and impact the rock and gravel layer and preliminarily locate the center of the borehole; the drilling assembly 300 locates the borehole inner wall and drill surface and drills the rock and soil interlayer; the balanced survey assembly 500 adjusts the balance stability of the survey device and cooperates with the eddy current survey assembly 100 and the balanced survey assembly 500 to divert and discharge rock and soil waste.

[0027] like Figure 2-Figure 6 As shown, due to the influx of groundwater and the difficulty of surveying underground rivers, the propulsion systems of existing underwater exploration equipment are blocked when passing through rock, soil, gravel and water layers, and the propulsion blades are easily blocked by the gravel. Existing underwater exploration equipment also lacks the necessary support for drilling holes, making it impossible to advance when encountering narrow caves. Surveying in the crisscrossing network of caves is extremely difficult.

[0028] The eddy current survey assembly 100 includes a vortex cover 110, a survey cabin 120, a power cabin 130, a survey top shaft 140, a vortex fan frame 150, and a vortex motor 160. The survey cabin 120 is located within the vortex cover 110, and the power cabin 130 is located at one end of the survey cabin 120. Specifically, the outer walls of the survey cabin 120, the outer walls of the power cabin 130, and the inner wall of the vortex cover 110 form a fluid cavity. The survey top shaft 140 is rotatably connected to the survey cabin 120. Specifically, the survey cabin 120 is equipped with multiple sets of bearings, and the survey top shaft 140 is fixed in these bearings to reduce vibration and impact generated during the drilling process. The vortex fan frame 150 is fixedly sleeved on one end of the survey top shaft 140. A gear shaping platform 141 is provided at one end of the survey top shaft 140. The gear shaping platform 141 is integrally formed with the survey top shaft 140 and is inserted into the vortex fan frame 150. A positioning tip 151 is provided at one end of the vortex fan frame 150, and the vortex fan frame 150 is tilted and retracted from the end surface of the reaming drill frame 310 and the surveying top shaft 140. The vortex motor 160 is disposed in the power cabin 130 and is screwed to the power cabin 130.

[0029] The output end of the eddy current motor 160 is driven by the survey top shaft 140, and the eddy current motor 160 is keyed to the survey top shaft 140. A jet cover 113 is provided at one end of the vortex cover 110, and the jet cover 113 is welded to the vortex cover 110. The jet cover 113 faces the tail cover 131 to guide the fluid.

[0030] The drilling assembly 300 includes a reaming drill rig 310, a wall positioning wheel 320, a surface positioning wheel 330, a reaming drill tool 340, and a digging drill tool 350. The reaming drill rig 310 is fixedly sleeved onto the surface of the vortex fan frame 150 and is screwed to the vortex fan frame 150. The reaming drill rig 310 faces the surface of the vortex cover 110. A transition ring support 313 is provided at one end of the reaming drill rig 310. The transition ring support 313 is welded to the reaming drill rig 310 and is flush with the vortex cover 110. The overall fluid design of the device is optimized. The wall positioning wheel 320 is evenly connected to the reaming drill frame 310 for rotation. The reaming drill frame 310 has evenly embedded wall positioning capsules 311 welded to the reaming drill frame 310. The wall positioning wheel 320 is rotatably connected within the wall positioning capsules 311 and is connected to the reaming drill frame 310 through a bearing connection. The rotation profile of the wall positioning wheel 320 is higher than the rotation profile of the reaming drill tool 340, which allows positioning of the inner wall of the borehole. The surface positioning wheel 330 is evenly connected to the reaming drill frame 310 for rotation. The surface positioning capsules 312 are evenly embedded in the reaming drill frame 310 and welded to the reaming drill frame 310.

[0031] The drill surface positioning wheel 330 is rotatably connected to the drill surface positioning chamber 312 and is connected to the drill surface positioning chamber 312 via a bearing. The rotational profile of the drill surface positioning wheel 330 is higher than that of the drill surface positioning wheel 330, which is used to position the drill surface. The reaming drill 340 is evenly mounted on the reaming drill frame 310 and is screwed to the reaming drill frame 310 to drill the inner wall of the drill hole. The digging drill 350 is evenly mounted on the vortex fan frame 150 to drill the drill surface.

[0032] The balanced survey assembly 500 includes an circumferential propeller 510, an axial propeller 520, an anti-collision guide vane 530, a waste slag guide vane 540, and a surveyor 550. The circumferential propeller 510 is evenly buried around the vortex cover 110, and the axial propeller 520 is evenly buried around the vortex cover 110. A propulsion cabin 111 is buried around the vortex cover 110 and is welded to the vortex cover 110. A suspension frame 112 is provided in the propulsion cabin 111 and is welded to the propulsion cabin 111. The circumferential propeller 510 and the axial propeller 520 are both provided on the suspension frame 112 and are screwed to the suspension frame 112. The circumferential propeller 510 faces the survey top shaft 140, and the axial propeller 520 faces the side wall of the propulsion cabin 111. Anti-collision guide vanes 530 are evenly distributed between the survey cabin 120 and the vortex cover 110 and are welded to both. The vortex fan frame 150 faces the anti-collision guide vanes 530 to guide the fluid. Waste residue guide vanes 540 are evenly distributed between the power cabin 130 and the vortex cover 110 and are welded to both.

[0033] Among them, the anti-collision guide vane 530 is directed toward the waste slag guide vane 540 to guide the fluid. The surveyor 550 is set at one end of the power cabin 130. A tail shroud 131 is set at one end of the power cabin 130. The tail shroud 131 is welded to the power cabin 130 to facilitate the sealing and waterproofing of the power cabin 130. The tail shroud 131 automatically reduces the outline diameter of the power cabin 130 to avoid fluid impact. A sealing flange 132 is set at one end of the tail shroud 131. The sealing flange 132 is welded to the tail shroud 131. The surveyor 550 is set on the sealing flange 132 and is screwed to the sealing flange 132 to survey the criss-crossing caves in the reservoir area.

[0034] The survey device achieves underwater movement and direction changes through the combined action of the radial thrust of the annular propeller 510 and the axial thrust of the axial propeller 520. The survey device also collects data on the water-filled areas of the coal mine goaf via the survey device 550 and transmits it to a remote terminal. When the survey device encounters Rongrong, the survey device 550 detects and selects a weak point in the rock wall. The annular propeller 510 and the axial propeller 520 propel the reaming drill rig 310 so that its front face faces the rock wall. The positioning tip 151 at one end of the vortex fan rig 150 is aligned with the rock wall. The vortex motor 160 controls the speed of the vortex fan rig 150. Under the thrust of the vortex, the drill face positioning wheel 330 first contacts the rock wall for cutting and positioning. This, combined with the positioning tip 151 to center the hole, repeatedly corrects drilling errors using the annular propeller 510 and the axial propeller 520. The eddy current motor 160 increases the rotational speed of the eddy current fan frame 150, and the reaming drill 340 and the digging drill 350 drill the rock wall. Because the end face of the eddy current fan frame 150 tilts and retracts from the reaming drill frame 310 and the surveying top shaft 140, the rock wall wrapped by the eddy current fan frame 150 forms a cone, and the positioning tip 151 and the drill surface positioning wheel 330 cooperate to cut and position the borehole. Maintaining the continuous propulsion of the eddy current motor 160, the reaming drill 340 drills and expands the inner wall of the borehole, and the drill wall positioning wheel 320 cuts and positions the inner wall of the borehole, adapting to the changes in the structural and compositional properties of the rock wall, and increasing the stability of underwater terrain drilling. Without the need for force support from the cave wall, the suspended cave can be used to drill through the narrow rock wall, enabling the survey of criss-crossing caves and making underwater terrain survey more convenient.

[0035] Compared with traditional manipulator drilling, the overall fluid design of the survey device, the transition ring support 313 is flush with the vortex cover 110, reducing the interference of the inner wall of the borehole on the movement of the survey device. Through the streamlined design of the outer wall of the survey cabin 120, the outer wall of the power cabin 130 and the inner wall of the vortex cover 110, combined with the guidance of the fluid by the anti-collision guide vanes 530 and the waste guide vanes 540, and through the bunching effect of the vortex, the drilling thrust direction of the survey device is more concentrated and the drilling stability is higher. The tail cover 131 automatically reduces the outline diameter of the power cabin 130, reducing the impact damage of the drilling waste fluid on the tail surveyor 550. Compared with the traditional manipulator drilling waste handling, no relevant settings are required. The waste fluid is guided by the spray cover 113, and the waste fluid ejected is concentrated and sprayed outward, reducing blockage in the borehole and facilitating the overall fluid design of the survey device. The buried annular propeller 510 and the axial propeller 520 reduce interference with the borehole inner wall during drilling. Combined with the water absorption effect of the vortex fan frame 150, waste residue generated by the reaming drill 340 and the digging drill 350 during drilling is drawn into the vortex cover 110, reducing the risk of waste residue and debris clogging the propulsion device blades. This provides the surveying device's propulsion system with high stability and low propulsion interference resistance.

[0036] The risk of collapse in goaf areas of coal mines is high. Falling rocks and localized cave roof subsidence threaten the practical safety of underwater terrain survey equipment. The surveyor 550 promptly monitors falling rocks and collapses, and the eddy current motor 160 controls the rotation of the vortex fan frame 150 to generate a propulsion flow, accelerating escape from the danger zone. The circumferential placement of the annular thruster 510 and axial thruster 520 increases the fault tolerance of thruster damage, while the vortex cover 110 protects some thrusters, maintaining propulsion power in real time. The survey equipment is highly safe and stable, making it suitable for surveying complex underground caves.

[0037] Specifically, the underwater topographic survey equipment operates as follows: The survey device, driven by the combined radial thrust of the annular propeller 510 and the axial thrust of the axial propeller 520, achieves underwater movement and direction changes. The survey device, using the surveyor 550, collects data on the water-filled areas of the coal mine goaf and transmits it to a remote terminal. When the survey device encounters a rock and soil fault between water-filled goafs, the surveyor 550 detects and selects weak points in the rock wall. The annular propeller 510 and the axial propeller 520 propel the reaming drill rig 310 so that its front face faces the rock wall. The positioning tip 151 at one end of the vortex fan frame 150 is aligned with the rock wall. The vortex motor 160 controls the rotational speed of the vortex fan frame 150. Under the thrust of the vortex, the drill face positioning wheel 330 first contacts the rock wall for cutting and positioning. This, combined with the positioning tip 151 to center the hole, repeatedly corrects drilling errors using the annular propeller 510 and the axial propeller 520. The eddy current motor 160 increases the rotational speed of the eddy current fan frame 150, and the reaming drill 340 and the digging drill 350 drill the rock wall. Because the end face of the eddy current fan frame 150 tilts and retracts from the reaming drill frame 310 and the surveying top shaft 140, the rock wall wrapped by the eddy current fan frame 150 forms a cone, and the positioning tip 151 and the drill surface positioning wheel 330 cooperate to cut and position the borehole. Maintaining the continuous propulsion of the eddy current motor 160, the reaming drill 340 drills and expands the inner wall of the borehole, and the drill wall positioning wheel 320 cuts and positions the inner wall of the borehole, adapting to the changes in the structural and compositional properties of the rock wall, and increasing the stability of underwater terrain drilling. Without the need for force support from the cave wall, the suspended cave can be used to drill through the narrow rock wall, enabling the survey of criss-crossing caves and making underwater terrain survey more convenient.

[0038] Furthermore, compared with traditional manipulator drilling, the overall fluid design of the survey device, the transition ring support 313 is flush with the vortex cover 110, reducing the interference of the inner wall of the borehole on the movement of the survey device. Through the streamlined design of the outer wall of the survey cabin 120, the outer wall of the power cabin 130 and the inner wall of the vortex cover 110, combined with the guidance of the fluid by the anti-collision guide vanes 530 and the waste guide vanes 540, and through the bunching effect of the vortex, the thrust direction of the survey device drilling is more concentrated, and the drilling stability is higher. The tail cover 131 automatically reduces the outline diameter of the power cabin 130, reducing the impact damage of the drilling waste fluid on the tail surveyor 550. Compared with traditional manipulator drilling waste handling, no relevant settings are required. The waste fluid is guided by the spray cover 113, and the waste fluid ejected is concentrated and sprayed outward, reducing blockage in the borehole and facilitating the overall fluid design of the survey device. The buried annular propeller 510 and the axial propeller 520 reduce interference with the borehole inner wall during drilling. Combined with the water absorption effect of the vortex fan frame 150, waste residue generated by the reaming drill 340 and the digging drill 350 during drilling is drawn into the vortex cover 110, reducing the risk of waste residue and debris clogging the propulsion device blades. This provides the surveying device's propulsion system with high stability and low propulsion interference resistance.

[0039] Furthermore, some karst formations pose a risk of collapse, threatening the practical safety of the underwater terrain survey device. The surveyor 550 promptly monitors rockfall and collapse, and the vortex motor 160 controls the rotation of the vortex fan frame 150 to create a propulsion flow, accelerating escape from the danger zone. The circumferential placement of the annular thruster 510 and axial thruster 520 increases the tolerance for thruster damage, while the vortex cover 110 protects some thrusters, maintaining propulsion power in real time. The overall safety and stability of the survey device are highly adaptable to surveys in complex hydrogeological conditions.
