Description

Technical Field

[0001] The present invention relates to the technical field of surveying devices, and particularly to a hydrological environment surveying device for hydropower generation. Background Art

[0002] Hydrological survey is the basis of hydropower generation, providing basic data support for hydropower generation. Groundwater level survey is an important project in hydrological survey. Groundwater level data can reveal the permeability of rock formations in the reservoir area and predict the leakage risk after the reservoir is impounded, playing a key role in hydropower generation.

[0003] A groundwater level surveying device for hydrogeology and its using method disclosed in a Chinese patent with the publication number CN115290164B. By installing a floating board at the bottom of the installation plate where the camera is installed, when the floating board touches the groundwater surface, the pulling force on the towing rope is reduced, causing the compression spring to reset and push the lifting plate and the movable block upward. The relative position between the movable block and the reference board changes. Above the ground, the staff can determine that the floating board has reached the groundwater level according to the position of the movable block, compare the position of the starting marking board, mark the towing rope at the position flush with it, and finally measure the length of the towing rope from the position where the floating board reaches to the marked position to obtain the groundwater level depth.

[0004] However, the above-mentioned existing technology has the following defects: It still requires the staff to manually measure the length between the starting mark and the final mark on the towing rope, and manual measurement may result in errors, making it less convenient to use. In addition, there is a time difference between when the staff observes the position change of the movable block and when the winding motor is turned off. During this time difference, the winding motor continues to work, causing the winding roller to continue to release the rope. The final mark coordinate recorded by the staff on the towing rope is greater than the actual mark coordinate, that is, the length between the starting mark and the final mark on the towing rope measured by the staff is greater than the actual length, resulting in errors in the surveyed groundwater level.

Detailed implementation mode

[0032] Example 1, as Figures 1-5 and Figures 8-9 and Figure 11 shown, a hydrological environment survey device for hydropower generation proposed by the present invention includes a support mechanism, a wire pay-off mechanism, a wire limiting mechanism and a measuring mechanism;

[0033] The support mechanism includes a moving seat 1, plates a 2, plates b 3 and a plate c. There are two plates a 2 and they are arranged at the top of the moving seat 1; there are two plates b 3 and they are respectively connected to the tops of the two side plates a 2. One end of the plate b 3 is connected to the moving seat 1 through the plate c. The plate c and the plate a 2 are respectively located at both ends of the plate b 3, playing a role in stably supporting the plate b 3; a counterweight b is arranged on the moving seat 1 to enhance the stability of the moving seat 1 and ensure that the center of gravity of the whole device will not shift.

[0034] The wire pay-off mechanism is connected to the plate b 3 and is used to drive the survey component into the inner side of the survey hole. The wire pay-off mechanism includes a motor 6, a wire pay-off roller 4 and a rope 5; the rope 5 is wound on the surface of the wire pay-off roller 4; the motor 6 is installed on the plate b 3 and is in transmission connection with the wire pay-off roller 4. The motor 6 drives the wire pay-off roller 4 to rotate clockwise (refer to Figure 1 ) to pay out the rope, and the motor 6 drives the wire pay-off roller 4 to rotate counterclockwise (refer to Figure 1 ) to take in the rope.

[0035] The rope limiting mechanism includes roller a10, roller b17, hollow plate 18, fixed plate 19 and telescopic component 16; roller a10 and roller b17 are made of materials with a large friction coefficient such as rubber, and anti-slip patterns for increasing friction are provided on the surfaces of roller a10 and roller b17; there are two hollow plates 18 which are rotatably connected to roller a10 through rotating shaft a; there are two fixed plates 19 which are rotatably connected to roller b17 through rotating shaft b; one end of fixed plate 19 is inserted into the inner side of hollow plate 18; telescopic component 16 is arranged on fixed plate 19 and connected to hollow plate 18, and telescopic component 16 includes, but is not limited to, electric push rods and other devices that can drive hollow movement; a ratchet assembly is connected to one end of rotating shaft b, and the ratchet assembly can make roller b17 rotate only in one direction and provide a certain resistance when roller b17 rotates; fixed plate 19 is connected to plate b3 through plate d, so that the entire rope limiting mechanism can be fixed on plate b3.

[0036] A wire guide cylinder is sleeved outside the rope 5, and the wire guide cylinder is connected to plate d (refer to Figure 1 ), so that the rope 5 can vertically pass through the gap between roller a10 and roller b17.

[0037] In this embodiment, telescopic component 16 drives hollow plate 18 to move towards the direction of fixed plate 19, and then drives roller a10 to move towards the direction of roller b17, so that roller a10 and roller b17 clamp rope 5. When the wire releasing roller 4 releases the rope, under the action of the gravity of the survey component, rope 5 is pulled to pass through the gap between roller a10 and roller b17, and drives roller a10 and roller b17 to rotate under the action of friction (refer to Figure 1 roller a10 rotates clockwise, roller b17 rotates counterclockwise). Under the action of the ratchet assembly, a certain resistance is applied to the rotation of roller b17. When the survey component contacts the groundwater, the survey component will float on the water surface. At this time, the pulling force of the survey component on rope 5 is zero. Even if the wire releasing roller 4 continues to release the rope, roller a10 and roller b17 will not continue to rotate under the resistance applied by the ratchet assembly, and the rope 5 continuously released by the wire releasing roller 4 will not pass through the gap between roller a10 and roller b17. At this time, the rope 5 below roller a10 and roller b17 is still in a straight state, while the rope 5 above roller a10 and roller b17 is in a bent state, ensuring that when the survey component contacts the groundwater, the marked position of the rope 5 corresponding to the hole will not change, and further ensuring the accuracy of the groundwater level measurement.

[0038] The measuring mechanism includes a rope ruler 8, a roller a7, a roller b15, a screw 13, a guide rod 14 and a nut block 22; the roller a7 is of a hollow structure and has a very light mass itself; the screw 13 is rotatably connected to the plate b3, and the screw 13 is drivingly connected to the roller a7; one end of the roller a7 is connected to the rotating shaft b, and the other end of the roller a7 is connected to the plate b3 through the plate e, so that the roller a7 can be fixed on the plate b3; the nut block 22 is threadedly connected to the screw 13; the roller b15 is rotatably arranged on the outer peripheral surface of the nut block 22; the rope ruler 8 is wound around the surface of the roller b15 and one end of it is connected to the roller a7; a guide hole is provided inside the nut block 22; the guide rod 14 passes through the guide hole and is connected to the plate b3, the plate e is rotatably connected to the roller a7, and an indicating rod 12 is connected to the plate e; the indicating rod 12 extends above the roller a7 and a pointer 27 is slidably arranged thereon; one end of the roller a7 is connected with a synchronous pulley a; one end of the screw 13 is connected with a synchronous pulley b, and a synchronous belt is connected between the synchronous pulley b and the synchronous pulley a.

[0039] It should be noted that: when the wire pay-off roller 4 pays out the rope, the rope 5 moves downward, and the length of the rope 5 moving downward through the gap between the roller a10 and the roller b17 can be fed back by the number of turns of the roller b17 rotating (for example, when the length of the rope 5 moving downward is the circumference of the roller b17, the roller b17 rotates one turn); the cross-sectional diameter of the roller a7 is the same as the diameter of the roller b17, and the roller a7 winds the rope ruler 8 evenly without overlapping, ensuring that the winding length of the rope ruler 8 by the roller a7 is the same for each turn of the roller a7, and ensuring that the winding amount of the rope ruler 8 by the roller a7 can accurately reflect the effective length of the rope 5 when the survey component contacts the groundwater, that is, the groundwater level value.

[0040] In this embodiment, the rotation of the roller b17 drives the rotation of the roller a7, the roller a7 drives the rotation of the synchronous pulley a, the synchronous pulley a drives the synchronous pulley b to rotate through the synchronous belt, and then drives the screw 13 to rotate, so that the nut block 22 moves along the screw 13, the nut block 22 drives the roller b15 to move along the screw 13, and the roller b15 drives the rope ruler 8 thereon to move, so that the winding point of the rope ruler 8 by the roller a7 moves continuously, ensuring that the rope ruler 8 on the roller b15 can be evenly wound on the roller a7. During the movement of the rope ruler 8, it will push the pointer 27 to move, ensuring that the pointer 27 is always in contact with the rope ruler 8 and is used to indicate the scale on the rope ruler 8.

[0041] Embodiment 2, as Figure 10As shown in the figure, a hydrological environment survey device for hydropower generation proposed by the present invention. Compared with the first embodiment, the structure of the survey component is also introduced in detail in this embodiment. The survey component includes a mounting plate 26, a counterweight a 24, a camera 23, and a floating plate 25. The camera 23 is provided at the bottom end of the mounting plate 26. The floating plate 25 is connected to the mounting plate 26 and is located below the camera 23. The counterweight a 24 is provided at the top end of the mounting plate 26 to increase the weight of the survey component. The free end of the rope 5 passes through the gap between the roller a 10 and the roller b 17 and is connected to the mounting plate 26. Two symmetric bidirectional lead screws are rotatably provided at the top end of the mounting plate 26. L-shaped plates are threadedly connected to the bidirectional lead screws. One end of the L-shaped plate is connected to a transfer block. The bottom end of the transfer block is hinged to an inclined plate. A guide wheel is provided at one end of the inclined plate. A shock-absorbing spring 20 is connected between the inclined plate and the transfer block.

[0042] In this embodiment, when the floating plate 25 contacts the groundwater, under the buoyancy of the floating plate 25, the entire survey component floats on the water surface. At this time, the downward pulling force of the survey component on the rope 5 is zero.

[0043] By rotating the bidirectional lead screw, the guide wheel is brought into contact with the inner wall of the survey hole. When the survey component moves downward inside the survey hole, the guide wheel can play a guiding and protecting role for the entire survey component. The shock-absorbing spring 20 can play a shock-absorbing and buffering role for the entire survey component when the guide wheel contacts a foreign object.

[0044] Embodiment Three, as Figures 6-7 As shown in the figure, a hydrological environment survey device for hydropower generation proposed by the present invention. Compared with the second embodiment, the ratchet assembly is also introduced in detail in this embodiment. The ratchet assembly includes a ratchet 9, a helical gear 21, a housing 11, and a spring 20. The housing 11 is connected to the plate b 3. The ratchet 9 is connected to the rotating shaft b. The helical gear 21 is slidably provided inside the housing 11. The spring 20 is provided inside the housing 11 and its two ends are respectively connected to the housing 11 and the helical gear 21. The helical gear 21 meshes with the ratchet 9, and the helical gear 21 has an arc-shaped inclined surface only on one side.

[0045] In this embodiment, when the rope 5 moves downward, the roller b 17 rotates counterclockwise downward (refer to Figure 5), roller b17 drives the ratchet 9 to rotate counterclockwise. When the ratchet 9 rotates, the inclined teeth on its surface will squeeze the inclined surface of the bevel teeth 21, thereby generating a component force on the bevel teeth 21 along the direction of the housing 11. Under the action of the component force, the bevel teeth 21 will be squeezed into the inside of the housing 11, and at the same time, the bevel teeth 21 will compress the spring 20. The elastic force of the spring 20 will generate resistance to the bevel teeth 21 entering the housing 11, thereby generating resistance to the rotation of the ratchet 9; if the rope 5 has a tendency to move upward, the roller b17 will have a tendency to rotate clockwise, and the roller b17 drives the ratchet 9 to rotate clockwise. If the ratchet 9 rotates clockwise, the inclined teeth on its surface will be blocked by the straight surface of the bevel teeth 21 and cannot rotate, thereby blocking the ratchet 9 from rotating, and then blocking the roller b17 from rotating, so that the rope 5 cannot move upward, and the pay-off roller 4 can retract the excess rope 5 (the rope 5 in the curved part above the roller a10 and the roller b17).

[0046] It is worth noting that one end of the bevel tooth 21 located on the inner side of the shell 11 and the inner bottom end of the shell 11 are magnetically attracted to each other. By manually moving the bevel tooth 21, the part of the bevel tooth 21 retracted into the shell 11 is greatly increased, that is, the one end of the bevel tooth 21 located on the inner side of the shell 11 and the inner bottom end of the shell 11 are significantly close. At this time, the magnetic attraction force between the two is greater than the elastic force generated when the spring 20 is compressed, thereby realizing the limiting function of the bevel tooth 21 when it is retracted into the inner side of the shell 11, thereby releasing the limiting function of the bevel tooth 21 on the ratchet 9.

[0047] In summary, before using the present invention, it is necessary to calibrate "zero" first. The steps of calibrating "zero" are as follows: first turn on the motor 6, and the motor 6 drives the pay-off roller 4 to rotate clockwise (refer to Figure 1 ), so that the survey component moves down to the hole mouth of the survey hole, at this time the recording pointer 27 points to the scale at the rope ruler 8 as the initial scale.

[0048] Then, the guide wheel is brought into contact with the inner wall of the survey hole by rotating the bidirectional screw rod, and the motor 6 is turned on. The motor 6 drives the pay-off roller 4 to continue to rotate and pay the rope, so that the survey component enters the survey hole. During the downward movement of the survey component, the rope 5 is continuously pulled through the gap between the roller a10 and the roller b17 by its own gravity. When the rope 5 passes through the gap between the roller a10 and the roller b17, the friction between the rope 5 and the roller a10 and the roller b17 drives the roller a10 and the roller b17 to rotate (refer to Figure 1The roller a10 rotates clockwise and the roller b17 rotates counterclockwise. The rotation of the roller b17 drives the ratchet 9 and the drum a7 to rotate counterclockwise. When the ratchet 9 rotates, the inclined teeth on its surface will squeeze the inclined surface of the helical gear 21, thereby generating a component force along the direction of the housing 11 on the helical gear 21. Under the action of the component force, the helical gear 21 will be squeezed into the housing 11. At the same time, the helical gear 21 will compress the spring 20, and the elastic force of the spring 20 will generate a resistance to the entry of the helical gear 21 into the housing 11, thereby generating a resistance to the rotation of the ratchet 9, and thus providing a resistance to the rotation of the roller b17, so that the rope 5 can only pass through the gap between the roller a10 and the roller b17 under the action of the gravity of the surveying component.

[0049] When the drum a7 rotates counterclockwise, it will wind the rope ruler 8. Since the cross-sectional diameter of the drum a7 is the same as the diameter of the roller b17, that is, the circumferences of the outer peripheral surfaces of the drum a7 and the roller b17 are the same. When the rope 5 drives the roller b17 to rotate a corresponding number of turns, the drum a7 also rotates a corresponding number of turns and winds the rope ruler 8 a corresponding number of turns at the same time. The length of the wound rope ruler 8 is the downward movement length of the rope 5. When the drum a7 rotates, it drives the synchronous pulley a to rotate. The synchronous pulley a drives the synchronous pulley b to rotate through the synchronous belt, and then drives the screw 13 to rotate, so that the nut block 22 moves along the screw 13 (the nut block 22 will not rotate with the screw 13 under the limiting action of the guide rod 14). The nut block 22 drives the drum b15 to move along the screw 13, and the drum b15 drives the rope ruler 8 thereon to move, so that the winding point of the rope ruler 8 on the drum a7 continuously moves, ensuring that the rope ruler 8 on the drum b15 can be evenly wound on the drum a7, ensuring that the length of the rope ruler 8 wound by the drum a7 per rotation is the same. During the movement of the rope ruler 8, it will push the pointer 27 to move, ensuring that the pointer 27 is always in contact with the rope ruler 8 and is used to indicate the scale on the rope ruler 8.

[0050] When the survey component reaches the groundwater, the floating plate 25 will first come into contact with the water surface. Under the buoyancy of the floating plate 25, the entire survey component floats on the water surface. At this time, the survey component no longer moves downward, and the downward pulling force of the survey component on the rope 5 is zero. Under the resistance provided by the ratchet assembly to the roller b17, the rope 5 no longer continues to pass through the gap between the roller a10 and the roller b17. At the same time, the roller b17 also stops rotating, and the drum a7 also stops rotating and no longer winds the measuring tape 8 (there is a large frictional force at the rotational connection of the outer peripheral surface of the drum b15 and the nut block 22, ensuring that when the drum a7 stops winding the measuring tape 8, the drum b15 will not continue to rotate due to inertia). When the staff observes that the rope 5 above the roller a10 and the roller b17 continues to bend, it indicates that the rope 5 no longer passes through the gap between the roller a10 and the roller b17, indicating that the survey component has reached the groundwater. The staff can then turn off the motor 6, causing the wire reel 4 to stop paying out the rope. At this time, read the scale where the pointer 27 points to the measuring tape 8, and subtract the initial scale from the scale read at this time to obtain the groundwater level value. Since during the process from when the staff realizes that the survey component has reached the groundwater to when the staff turns off the motor 6, although the motor 6 still continuously drives the wire reel 4 to rotate, the rope 5 paid out by the wire reel 4 will not pass through the gap between the roller a10 and the roller b17. Therefore, the roller b17 will not drive the drum a7 to rotate either, ensuring that when the survey component contacts the groundwater, the drum a7 stops winding the measuring tape 8, thus ensuring the accuracy of the measuring tape 8 in measuring the groundwater level and realizing the automatic measurement function, significantly reducing the workload of groundwater level survey.

[0051] Finally, manually move the helical gear 21, so that the part of the helical gear 21 retracted into the housing 11 increases significantly, that is, the distance between the end of the helical gear 21 located inside the housing 11 and the bottom end inside the housing 11 is significantly reduced. At this time, the magnetic suction force between the two is greater than the elastic force generated when the spring 20 is compressed, realizing the limiting function when the helical gear 21 retracts into the inner side of the housing 11, so that the limiting of the helical gear 21 on the ratchet 9 can be released, enabling the ratchet 9 to rotate bidirectionally. At this time, turn on the motor 6 again, and the motor 6 drives the wire reel 4 to rotate counterclockwise (refer to Figure 1 ), start winding the rope 5, and the rope 5 pulls the survey component upward to recover the survey component. When the rope 5 moves upward through the gap between the roller a10 and the roller b17, the rope 5 drives the roller b17 to rotate clockwise (refer to Figure 1 ), the roller b17 drives the drum a7 to rotate clockwise, and the wound measuring tape 8 is paid out. At this time, the screw 13 rotates clockwise synchronously, causing the nut block 22 to drive the drum b15 to reset. After the drum b15 is reset, the staff manually rotates the drum b15 to wind the measuring tape 8.

[0052] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
