Description

Technical Field

[0001] This invention relates to the field of underground exploration technology, and in particular to an auxiliary surveying device for groundwater flow velocity and direction. Background Technology

[0002] Determining the direction and velocity of groundwater flow is of great significance for environmental monitoring, hydrogeology, and natural resources. In environmental monitoring, accurate monitoring of groundwater flow direction and velocity can promptly determine groundwater pollution and monitor covert sewage discharge in real time. In hydrogeology, groundwater flow direction and velocity can provide accurate reference data for geological exploration and engineering construction. In natural resources, groundwater flow direction and velocity can be used to predict water resource loss.

[0003] Chinese utility model patent CN218003452U discloses a groundwater flow velocity and direction measuring device, including an underwater detector. The underwater detector is a sealed cylindrical structure with a pressure sensor on its outer surface. A signal processing and transmission unit compartment is located inside the underwater detector, sealed to the underwater detector via a top connector. The upper part of the underwater detector is connected to a ground component. The signal processing and transmission unit compartment contains a signal processing and transmission unit with a built-in microprocessor connected to a ground-based acquisition and display device via a transmission cable. The pressure sensor is connected to the signal processing and transmission unit via a pressure sensor cable. This device can achieve real-time monitoring of groundwater flow direction and velocity based on different seepage field characteristics. Furthermore, the device has reasonable manufacturing costs, low operating costs, good adaptability, and does not pollute the environment, making it of significant engineering application value.

[0004] However, existing measurement techniques mostly employ pumping experiments or tracer methods, which are very cumbersome and have long measurement cycles. This device uses dedicated measuring instruments to accurately measure the direction and velocity of water flow. Existing data collection methods often involve directly connecting ropes and cables to the measuring instruments and sending them underground, which can damage the measuring instruments during the descent. This invention is designed to assist in measurement and protect the measuring device, preventing damage from collisions during descent and thus ensuring measurement accuracy. Summary of the Invention

[0011] One end of the connecting rod is rotatably connected to the shaft on the drill bit claw, and the other end is connected to one end of the tension spring. The other end of the tension spring is fixedly installed on the short shaft inside the drill barrel. The short shafts on both sides of the connecting rod are simultaneously slidably installed in the grooves inside the drill barrel. The round head at the lower end of the connecting rod is slidably connected to the threaded groove on the long sleeve. There are several drill bit claws. The short shafts on the sides of the drill bit claws are slidably installed in the grooves inside the drill barrel. The cover plate is rotatably connected to the shaft below the drill bit claw. At the same time, the cover plate is slidably installed in the grooves inside the drill barrel. The shaft in the hollowed-out groove in the middle of the cover plate is rotatably connected to one end of the telescopic rod. The other end of the telescopic rod is rotatably connected to the shaft in the hollowed-out groove below the drill bit claw.

[0012] Preferably, the drilling mechanism includes: a buckle, a rope, and a cable;

[0013] The buckle is fixedly installed at the tail end of the long sleeve, the rope is fixedly installed on the buckle, and the cable passes through the opening at the tail end of the long sleeve and connects to the electrical instrument inside the long sleeve, thereby supplying power to the internal equipment.

[0014] Preferably, the floating mechanism includes: a fixing frame, a floating ring, and a sensing element;

[0015] The fixed frame is slidably installed on the inner wall of the long sleeve, the floating ring is fixedly installed inside the ring at the lower end of the fixed frame, and the sensing element is fixedly installed on the inner wall of the long sleeve.

[0016] Preferably, the clamping mechanism includes: a locking ring, a retaining ring, and an inner sleeve;

[0017] The short rod on the inner side of the locking ring is fixedly connected to the retaining ring, and the short rod on the inner side of the locking ring is slidably connected to the sliding groove on the long sleeve. The retaining ring is rotatably installed on both sides of the inner sleeve, and the round hole on the inner sleeve is slidably connected to the long rod inside the long sleeve.

[0018] Preferably, the clamping mechanism includes: a slider, a clamping plate, a compression spring A, and a compression spring B;

[0019] There are four sliders, all of which are slidably mounted on the grooves of the inner ring of the inner sleeve. The short rods on the clamping plate are slidably mounted in the round holes on the sliders. The two ends of the compression spring A are in contact with the slider and the inner sleeve, respectively, and the two ends of the compression spring B are in contact with the slider and the clamping plate, respectively.

[0020] Preferably, the clamping mechanism includes: a connecting ring and an electric cylinder;

[0021] The connecting ring is rotatably mounted on the outside of the retaining ring, the piston rod of the electric cylinder is fixedly connected to the connecting ring, and the cylinder body of the electric cylinder is fixedly mounted on the inner wall of the long sleeve.

[0022] Preferably, the floating ring is filled with hydrogen gas, which generates strong buoyancy from the limited volume of the floating ring, allowing it to always float on the water surface.

[0023] The beneficial effects of this invention compared to the prior art are:

[0024] 1. In use, the stepper motor starts, driving the driven gear to rotate. The driven gear drives the drill barrel to rotate, and the connecting rod inside the drill barrel is simultaneously driven to rotate. The round head at the lower end of the connecting rod slides on the threaded groove on the long sleeve, thereby driving the connecting rod to slide outward on the groove inside the drill barrel. The connecting rod drives the drill bit claw to slide outward until it slides to the end of the groove. When the drill bit claw extends, it drives the cover plate to extend. The cover plate closes under the action of the telescopic rod, thereby protecting the internal measuring instruments. After the drill bit claw extends, it will continue to rotate, clearing minor obstacles encountered during descent.

[0025] 2. When the device touches the water surface and continues to submerge, the floating ring will rise to the surface, causing the ring on the fixed frame to contact the sensing element and generate data that is transmitted to the ground operating computer. When the fixed frame reaches the preset position of the sensing element, the device stops submerging, which can reach the optimal measurement position very accurately.

[0026] 3. In use, the present invention can be manually rotated by rotating the locking ring, which drives the retaining ring to rotate. The protrusion on the retaining ring locks the slider, thereby squeezing the slider inward and sliding it. Then the slider drives the clamping plate to slide inward, so that the clamping plate clamps the measuring instrument. The measuring instrument is placed stably in the equipment and will not be damaged by collisions, which is very safe. Attached Figure Description

These illustrative embodiments and descriptions are used to explain the invention, but are not intended to limit the scope of the invention. Furthermore, detailed descriptions of known technologies that are unnecessary to illustrate the features of the present invention are omitted.

[0040] Please see Figure 1-14 As shown, an auxiliary surveying device for groundwater flow velocity and direction includes a drilling mechanism 1, a floating mechanism 2, and a clamping mechanism 3.

[0041] The drilling mechanism 1 is rotatably mounted on the outer ring of the long sleeve 105, the floating mechanism 2 is slidably mounted on the inner ring of the long sleeve 105, and the clamping mechanism 3 is movably mounted at the upper end of the long sleeve 105. The drilling mechanism 1 is used to protect the measuring instrument and clear the way for the equipment to dive, clearing away minor collapses and soil obstacles. The floating mechanism 2 is used to sense the water surface, thereby positioning the equipment at the most suitable position for measuring the water flow velocity and direction. The clamping mechanism 3 is used to fix the measuring instrument and, after reaching the measurement position, push the measuring instrument out of the equipment to contact the water flow, thereby measuring the water flow velocity and direction.

[0042] In one optional embodiment of the present invention, such as Figure 4 As shown, the drilling mechanism 1 includes: a protective shell 101, a drill barrel 102, a stepper motor 103, a driven gear 104, and a long sleeve 105;

[0043] The protective shell 101 is fixedly installed on the outside of the long sleeve 105, and the drill barrel 102 is rotatably connected to the long sleeve 105. The stepper motor 103 is fixedly installed on the outside of the long sleeve 105, and the motor shaft of the stepper motor 103 is fixedly connected to the rotating shaft of the driven gear 104. The rotating shaft of the driven gear 104 is rotatably installed on the hinge seat on the outer ring of the long sleeve 105. The driven gear 104 meshes with the inner ring teeth of the drill barrel 102. The rotation of the driven gear 104 can drive the drill barrel 102 to rotate, thereby performing obstacle clearing work.

[0044] In one optional embodiment of the present invention, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the drilling mechanism 1 includes: a drill barrel 102, a long sleeve 105, a connecting rod 106, a tension spring 107, a drill bit claw 108, a cover plate 109, and a telescopic rod 110.

[0045] One end of the connecting rod 106 is rotatably connected to the shaft on the drill bit claw 108, and the other end is connected to one end of the tension spring 107. The other end of the tension spring 107 is fixedly installed on a short shaft inside the drill barrel 102. The tension spring 107 generates tension, which is used to pull the drill bit claw 108 back to its original position when the drill barrel 102 reverses. The short shafts on both sides of the connecting rod 106 are simultaneously slidably installed in the grooves inside the drill barrel 102. The round head at the lower end of the connecting rod 106 is slidably connected to the threaded groove on the long sleeve 105. There are several drill bit claws 108, and the short shafts on the sides of the drill bit claws 108 slide... Installed in the groove inside the drill barrel 102, the cover plate 109 is rotatably connected to the shaft under the drill bit claw 108. At the same time, the cover plate 109 is slidably installed in the groove of the drill barrel 102. The shaft in the hollowed-out groove in the middle of the cover plate 109 is rotatably connected to one end of the telescopic rod 110. The other end of the telescopic rod 110 is rotatably connected to the shaft in the hollowed-out groove under the drill bit claw 108. The telescopic rod 110 generates elastic force. The function of the telescopic rod 110 is to give the cover plate 109 an elastic force when the cover plate 109 is taken out of the groove by the drill bit claw 108, so that several cover plates 109 close to protect the measuring instrument.

[0046] In one optional embodiment of the present invention, such as Figure 9 As shown, the drilling mechanism 1 includes: a buckle 111, a rope 112, and a cable 113;

[0047] The buckle 111 is fixedly installed at the tail end of the long sleeve 105, and the rope 112 is fixedly installed on the buckle 111. The long sleeve 105 is slowly lowered through the rope 112 to measure the direction and velocity of the water flow. The cable 113 passes through the opening at the tail end of the long sleeve 105 and is connected to the electrical instruments inside the long sleeve 105 to supply power to the internal equipment.

[0048] Specifically, after the measuring instrument is installed, the equipment is lowered into the pre-drilled hole. During descent, the stepper motor 103 starts, driving the driven gear 104 to rotate. The driven gear 104 drives the drill barrel 102 to rotate, and the connecting rod 106 inside the drill barrel 102 is simultaneously driven to rotate. The round head at the lower end of the connecting rod 106 slides on the threaded groove on the long sleeve 105, thereby driving the connecting rod 106 to slide outward on the groove inside the drill barrel 102. The connecting rod 106 drives the drill bit claw 108 to slide outward until it slides to the end of the groove. The round head at the lower end of the connecting rod 106 also enters the end of the threaded groove on the long sleeve 105. The groove at this point is horizontal and will not drive the connecting rod 106 to continue sliding. When the drill bit claw 108 extends, it drives the cover plate 109 to extend. The cover plate 109 closes under the action of the telescopic rod 110, thereby protecting the measuring instrument inside. After the drill bit claw 108 extends, it will continue to rotate, clearing any minor obstacles encountered during descent. Once the equipment reaches the designated position, the stepper motor 103 rotates in the reverse direction, causing the drill bit claw 108 and the cover plate 109 to retract, exposing the measuring instrument for the next measurement step.

[0049] In one optional embodiment of the present invention, such as Figure 10 , Figure 11 As shown, the floating mechanism 2 includes: a fixed frame 201, a floating ring 202, and a sensing element 203;

[0050] The fixed frame 201 is slidably installed on the inner wall of the long sleeve 105. The floating ring 202 is fixedly installed in the ring at the lower end of the fixed frame 201. The sensing element 203 is fixedly installed on the inner wall of the long sleeve 105. When the equipment touches the water surface and continues to dive, the floating ring 202 will float up, so that the ring on the upper part of the fixed frame 201 will contact the sensing element 203, thereby generating data that is transmitted to the ground operation computer. When the fixed frame 201 reaches the preset position of the sensing element 203, the equipment stops diving.

[0051] In one optional embodiment of the present invention, such as Figure 12 , Figure 13 As shown, the clamping mechanism 3 includes: a locking ring 301, a retaining ring 302, and an inner sleeve 303;

[0052] The short rod inside the locking ring 301 is fixedly connected to the retaining ring 302. The short rod inside the locking ring 301 is slidably connected to the sliding groove on the long sleeve 105. The retaining ring 302 is rotatably installed on both sides of the inner sleeve 303. The round hole on the inner sleeve 303 is slidably connected to the long rod inside the long sleeve 105.

[0053] In one optional embodiment of the present invention, such as Figure 13 As shown, the clamping mechanism 3 includes: a slider 304, a clamping plate 305, a compression spring A 306, and a compression spring B 307;

[0054] There are four sliders 304, all of which are slidably installed on the grooves of the inner ring of the inner sleeve 303. When the retaining ring 302 rotates, the protrusions on the retaining ring 302 will lock the sliders 304, thereby squeezing the sliders 304 to slide inward. The short rod on the clamping plate 305 is slidably installed in the round hole on the slider 304. The two ends of the compression spring A306 are in contact with the slider 304 and the inner sleeve 303 respectively. The compression spring A306 generates elastic force, and its function is to drive the slider 304 to reset when the protrusions of the retaining ring 302 disengage from the slider 304. The two ends of the compression spring B307 are in contact with the slider 304 and the clamping plate 305 respectively. The compression spring B307 generates elastic force, and its function is to drive the clamping plate 305 to clamp the measuring device when the slider 304 is compressed inward, thereby creating a buffer for the clamping force and flexibly clamping the measuring instrument.

[0055] In one optional embodiment of the present invention, such as Figure 14 As shown, the clamping mechanism 3 includes: a connecting ring 308 and an electric cylinder 309;

[0056] The connecting ring 308 is rotatably mounted on the outside of the retaining ring 302, the piston rod of the electric cylinder 309 is fixedly connected to the connecting ring 308, and the cylinder body of the electric cylinder 309 is fixedly mounted on the inner wall of the long sleeve 105.

[0057] Specifically, when the equipment is in use, the tail end of the long sleeve 105 can be opened. After inserting the measuring instrument into the long sleeve 105, the cover is closed. After inserting the measuring instrument into the designated position, the locking ring 301 is manually rotated. The locking ring 301 drives the retaining ring 302 to rotate. The protrusion on the retaining ring 302 locks the slider 304, thereby squeezing the slider 304 to slide inward. The slider 304 drives the clamping plate 305 to slide inward, thereby clamping the measuring instrument with the clamping plate 305.

[0058] When the drill bit claw 108 and the cover plate 109 are retracted, the electric cylinder 309 is activated, the piston rod of the electric cylinder 309 retracts, which drives the connecting ring 308 to slide, thereby driving the inner sleeve 303 to slide, which in turn drives the measuring instrument clamped by the clamping plate 305 to slide, thereby exposing the measuring instrument to the equipment and entering the water, so as to measure the direction and velocity of the water flow.

[0059] In one optional embodiment of the present invention, such as Figure 10 , Figure 11 As shown, the floating ring 202 is filled with hydrogen gas, which generates strong buoyancy from the limited volume of the floating ring 202, allowing the floating ring 202 to always float on the water surface.

[0060] Working principle: Specifically, when the equipment is in use, the long sleeve 105 has an openable cover at its tail end. After inserting the measuring instrument into the long sleeve 105, close the cover. After inserting the measuring instrument into the designated position, manually rotate the locking ring 301. The locking ring 301 drives the retaining ring 302 to rotate. The protrusion on the retaining ring 302 locks the slider 304, thereby squeezing the slider 304 inward. The slider 304 drives the clamping plate 305 to slide inward, thereby clamping the measuring instrument with the clamping plate 305.

[0061] After the measuring instruments are installed, the equipment is lowered into the drilled hole. During descent, the stepper motor 103 starts, driving the driven gear 104 to rotate. The driven gear 104 drives the drill barrel 102 to rotate, and the connecting rod 106 inside the drill barrel 102 is simultaneously driven to rotate. The round head at the lower end of the connecting rod 106 slides on the threaded groove on the long sleeve 105, thereby driving the connecting rod 106 to slide outward on the groove inside the drill barrel 102. The connecting rod 106 drives the drill bit claw 108 to slide outward until it slides to the end of the groove. The round head at the lower end of the connecting rod 106 also enters the end of the threaded groove on the long sleeve 105. The groove at this point is horizontal and will not drive the connecting rod 106 to continue sliding. When the drill bit claw 108 extends, it drives the cover plate 109 to extend. The cover plate 109 closes under the action of the telescopic rod 110, thereby protecting the measuring instruments inside. After the drill bit claw 108 extends, it will continue to rotate, clearing any minor obstacles encountered during descent.

[0062] When the device touches the water surface and continues to descend, the floating ring 202 will rise to the surface, causing the ring on the fixed frame 201 to contact the sensing element 203, thereby generating data that is transmitted to the ground operating computer. When the fixed frame 201 reaches the preset position of the sensing element 203, the device stops descending.

[0063] Once the equipment reaches the designated position, the stepper motor 103 rotates in the reverse direction, causing the drill bit claw 108 and the cover plate 109 to retract, exposing the measuring instrument for the next measurement step.

[0064] After the drill bit claw 108 and cover plate 109 retract, the electric cylinder 309 is activated. The piston rod of the electric cylinder 309 retracts, causing the connecting ring 308 to slide, which in turn causes the inner sleeve 303 to slide, thereby causing the measuring instrument clamped by the clamping plate 305 to slide, thus exposing the measuring instrument to the equipment and allowing it to enter the water, thereby measuring the direction and velocity of the water flow. This device plays an auxiliary protective role in the measurement, preventing the measuring instrument from being damaged by impact, and making the measurement data more accurate.
