Abstract
Description
Technical Field
[0001] This invention relates to the field of hydrological surveying, and more particularly to a hydrological and water resources surveying device. Background Technology
[0002] Hydrological elements encompass various hydrological phenomena and variables. Precipitation, evaporation, and runoff are the fundamental elements of the hydrological cycle. Water level, flow velocity, discharge, water temperature, sediment load, ice jams, and water quality are also listed as hydrological elements. Hydrological flow velocity is one of the main factors constituting the hydrological situation at a specific location or region at a specific time. It is a primary physical quantity describing the hydrological situation, a measurement tool used to describe water flow, and a major scale reflecting changes in river hydrological conditions. Hydrological flow velocity data can be obtained through observation.
[0003] However, most current hydrological survey devices rely on power, but operators often encounter situations where there is no power when conducting surveys outdoors, making it inconvenient to carry out hydrological surveys. Furthermore, existing hydrological survey devices are prone to getting stuck by foreign objects in the water when being retrieved, making them difficult to retrieve. Existing hydrological survey devices are also prone to tilting when impacted by water currents, making the hydrological survey process very unstable. Summary of the Invention

Three fixed rings are fixedly connected to the upper part of the rotating shaft, and centrifugal rods are slidably connected to each of the three fixed rings. The centrifugal rods are located away from the rotating shaft. A first magnet is fixedly connected to one end of the shaft. A return spring is connected between the centrifugal rod and the first magnet. The return spring is sleeved on the centrifugal rod. Three ring frames are fixedly connected to the centrifugal disc. A second magnet is slidably connected to each of the three ring frames. The first magnet and the second magnet have opposite magnetic properties and will attract each other. Three triangular guide wheels are fixedly connected to the inner wall of the connecting frame. A secondary rope is fixedly connected to the second magnet. The secondary rope passes around the triangular guide wheels. A connecting ball is provided between the three secondary ropes. A traction line is fixedly connected to the top of the connecting ball between the three secondary ropes.
[0009] As a further preferred embodiment, the actuation mechanism includes a hollow wire, a handle, an annular base, a first winding reel, and a second triangular guide wheel. The top of the handle is fixedly connected to the annular base, and the first winding reel is rotatably connected to the annular base. The handle is rotatably connected to the first winding reel. The second triangular guide wheel is fixedly connected to the top of the first winding reel. A through hole is opened on the top of the first winding reel, and a hollow wire is fixedly connected inside the through hole. The hollow wire is wound on the first winding reel. The end of the hollow wire away from the first winding reel is fixedly connected to a hollow tube. The end of the hollow wire away from the first winding reel passes through the hollow tube. The end of the hollow wire away from the first winding reel contacts the connecting ball between the three auxiliary ropes. The traction line passes through the hollow wire and the through hole on the top of the first winding reel, and the traction line contacts the second triangular guide wheel.
[0010] As a further preferred embodiment, the indicating mechanism includes a second winding reel, an indicating shaft, and a torsion spring. The second winding reel is rotatably connected to the top of the first winding reel. A water speed scale is provided on the top of the second winding reel. The traction line is wound on the second winding reel. An indicating shaft is fixedly connected to the top of the first winding reel. The indicating shaft passes through the second winding reel. A torsion spring is connected between the second winding reel and the indicating shaft.
[0011] As a further preferred embodiment, a support mechanism is also included, which is mounted on the conical shell. The support mechanism includes horizontal rotating shafts, support frames, and small magnets. Three horizontal rotating shafts are rotatably connected to the conical shell, and support frames are fixedly connected to each of the three horizontal rotating shafts. The support frames are made of ferrous metal. Several pressure holes are opened at the bottom of the conical mesh, and the pressure holes are all connected to the water-pressing groove at the bottom of the conical mesh. Four small magnets are fixedly connected to the bottom of the conical mesh, and the small magnets and the bottom of the conical mesh are in contact with the bottom of the support frames. The small magnets will attract the bottom of the support frames.
[0012] As a further preferred embodiment, the housing also includes a hollow cone, to which the top of the housing is fixedly connected, and through which the hollow tube passes.
[0013] The beneficial effects of this invention are:
[0014] The operator places the casing, hollow tube, connecting frame, conical shell, and conical mesh into the water, causing them to sink to the bottom and remain vertical. The water flow then drives the rotating fan blades, causing the water velocity scale on the top of the second winding reel to rotate in front of the indicating shaft. The operator observes the water velocity scale on the top of the second winding reel, which points to the indicating shaft, to determine the water flow velocity in the surveyed area. This purely mechanical structure makes outdoor hydrological surveys more convenient for the operator. Furthermore, the shuttle-shaped structure reduces the likelihood of foreign objects getting stuck in the water during retrieval, thus facilitating easier recovery of the device.
[0015] When the conical mesh moves downward under the influence of gravity, the water jet will push the support frame and the horizontal rotating shaft to swing upward to a suitable angle, thereby supporting the shell, connecting frame, conical shell and conical mesh. In this way, the shell, hollow pipe, connecting frame, conical shell and conical mesh can remain more stable and vertical after sinking to the bottom of the water, which is conducive to more stable hydrological surveys.
[0016] When the shell, hollow tube, connecting frame, conical shell, and conical mesh are submerged in water, the hollow cone increases the buoyancy of the shell, thereby making the shell, hollow tube, connecting frame, conical shell, and conical mesh more stable and vertical after sinking to the bottom, thus enabling more stable hydrological surveys.

[0033] Example 1
[0034] A hydrological and water resources surveying device, such as Figures 1-14 As shown, it includes a housing 1, a hollow tube 11, a connecting frame 2, a conical shell 3, a conical mesh 4, a drive mechanism, a centrifugal rotation mechanism, an actuation mechanism, and an indicator mechanism. The top of the housing 1 is bolted to the hollow tube 11. The housing 1 is a hollow structure and is connected to the hollow tube 11. The bottom of the housing 1 is bolted to the connecting frame 2. The bottom of the connecting frame 2 is riveted to the conical shell 3. The bottom of the conical shell 3 is riveted to the conical mesh 4.

[0035] The drive mechanism includes a planetary gear 51, a circular shaft 52, a connecting shaft 53, and a rotating fan blade 54. The upper part of the conical shell 3 is connected to the planetary gear 51 by bolts. The bottom of the input shaft of the planetary gear 51 is connected to the circular shaft 52 by bolts.

Several shaped frames 61 are riveted to the top of the conical shell 3. Centrifugal discs 62 are riveted together among the shaped frames 61. A rotating shaft 63 is rotatably connected to the centrifugal disc 62. The bottom of the rotating shaft 63 is fixedly connected to the top of the output shaft of the planetary gear 51. Three fixed rings 64 are bolted to the upper part of the rotating shaft 63. A centrifugal rod 65 is slidably connected to each of the three fixed rings 64. The end of the centrifugal rod 65 away from the rotating shaft 63 is bolted... A first magnet 66 is bolted to the centrifugal disc 62. A return spring 67 is connected to the centrifugal rod 65 and the first magnet 66 via a hook. The return spring 67 is sleeved on the centrifugal rod 65. Three ring frames 68 are bolted to the centrifugal disc 62. A second magnet 69 is slidably connected to each of the three ring frames 68. The first magnet 66 and the second magnet 69 have opposite magnetic properties and will attract each other. Three triangular guide wheels 691 are bolted to the inner wall of the connecting frame 2. A secondary rope 693 is fixedly connected to the second magnet 69. The secondary rope 693 passes around the triangular guide wheels 691. A connecting ball is provided between the three secondary ropes 693. A traction line 692 is fixedly connected to the top of the connecting ball between the three secondary ropes 693.
[0037] The actuating mechanism includes a hollow wire 71, a handle 72, an annular base 73, a first winding reel 74, and a second triangular guide wheel 75. The top of the handle 72 is bolted to the annular base 73, and the first winding reel 74 is rotatably connected to the annular base 73. The handle 72 and the first winding reel 74 are rotatably connected. The top of the first winding reel 74 is bolted to the second triangular guide wheel 75. The top of the first winding reel 74 has a through hole, and a fixed part is fixed inside the through hole at the top of the first winding reel 74. A hollow wire 71 is connected, which is wound around a first winding reel 74. The end of the hollow wire 71 away from the first winding reel 74 is fixedly connected to a hollow tube 11. The end of the hollow wire 71 away from the first winding reel 74 passes through the hollow tube 11. The end of the hollow wire 71 away from the first winding reel 74 contacts a connecting ball between three auxiliary ropes 693. The traction line 692 passes through the through hole at the top of the hollow wire 71 and the first winding reel 74, and contacts the second triangular guide wheel 75.
[0038] The indicating mechanism includes a second winding reel 81, an indicating shaft 82, and a torsion spring 83. The second winding reel 81 is rotatably connected to the top of the first winding reel 74. A water speed scale is provided on the top of the second winding reel 81. The traction line 692 is wound on the second winding reel 81. The top of the first winding reel 74 is bolted to the indicating shaft 82, which passes through the second winding reel 81. A torsion spring 83 is connected between the second winding reel 81 and the indicating shaft 82 via a hook.
[0039] The operator approaches the riverbank to be surveyed, grasps handle 72, and lowers the housing 1, hollow tube 11, connecting frame 2, conical shell 3, and conical mesh 4 into the water. This causes the first winding reel 74 to unwind. The unwinding of the first winding reel 74 drives the second winding reel 81, triangular guide wheel 75, indicator shaft 82, and torsion spring 83 to rotate. Due to the gravity of the conical mesh 4, it causes the housing 1, hollow tube 11, connecting frame 2, and conical shell 3 to move downwards. Consequently, the housing 1 causes the hollow wire 71 to move downwards. Due to the buoyancy of the housing 1 in the water, it remains at the top of the connecting frame 2, thus causing the housing 1, hollow tube 11, connecting frame 2, conical shell 3, and conical mesh 4 to sink to the bottom and remain vertical. In a straight state, the water flow will drive the rotating fan blade 54 to rotate. The rotation of the rotating fan blade 54 will drive the connecting shaft 53 to rotate. The rotation of the connecting shaft 53 will drive the circular shaft 52 to rotate. The rotation of the circular shaft 52 will drive the planetary gear 51 to rotate. Under the deceleration effect of the planetary gear 51, the rotation of the planetary gear 51 will drive the rotating shaft 63 to rotate slowly. The rotation of the rotating shaft 63 will drive the three fixed rings 64 to rotate. The rotation of the fixed rings 64 will drive the centrifugal rod 65 to rotate. The rotation of the centrifugal rod 65 will drive the first magnet 66 to rotate. The first magnet 66 will attract the second magnet 69, causing the second magnet 69 to move. The movement of the second magnet 69 will drive the traction line 692 to move along the triangular guide wheel 691 towards the rotating shaft 63. Moving 692 will cause the second winding reel 81 to unwind, and the torsion spring 83 will be twisted, causing the water velocity scale on the top of the second winding reel 81 to rotate in front of the indicator shaft 82. The operator can observe the water velocity scale on the top of the second winding reel 81 pointed to by the indicator shaft 82 to know the water flow velocity in the surveyed area. After the survey is completed, the operator rotates the first winding reel 74 in the opposite direction. The reverse rotation of the first winding reel 74 will cause the second winding reel 81, the triangular guide wheel 75, the indicator shaft 82, and the torsion spring 83 to rotate in the opposite direction and reset, causing the first winding reel 74 to wind up. The winding of the first winding reel 74 will cause the hollow wire 71 to move upward. The upward movement of the hollow wire 71 will cause the housing 1, the hollow tube 11, the connecting frame 2, and the conical shell 3 to move upward as well. When the hollow wire 71 moves upward, causing the housing 1, hollow tube 11, connecting frame 2, and conical shell 3 to leave the water surface, the water flow no longer pushes the rotating fan blade 54 to rotate. When the rotating fan blade 54 stops rotating, the fixed ring 64, the round shaft 52, the planetary gear 51, the rotating shaft 63, the centrifugal rod 65, and the first magnet 66 will all stop rotating. The torsion spring 83 will reset. The reset of the torsion spring 83 will cause the second winding reel 81 to wind up. The winding of the second winding reel 81 will cause the traction wire 692 to move upward and reset. The upward movement and reset of the traction wire 692 will cause the auxiliary rope 693 to move along the triangular guide wheel 691 in a direction away from the rotating shaft 63 and reset. Then the operator continues to rotate the first winding reel 74 to complete the winding of the hollow wire 71.Thus, this device is a purely mechanical structure, making it more convenient for operators to conduct hydrological surveys outdoors. Furthermore, its spindle-shaped structure reduces the likelihood of foreign objects getting stuck in the water during retrieval, resulting in better recovery of the device.
[0040] Example 2
[0041] Based on Example 1, such as Figures 1-13 As shown, it also includes a support mechanism, which is set on the conical shell 3. The support mechanism includes a horizontal rotating shaft 91, a support frame 92, and small magnets 94. Three horizontal rotating shafts 91 are rotatably connected to the conical shell 3. Each of the three horizontal rotating shafts 91 is connected to a support frame 92 by bolts. The support frame 92 is made of iron metal. Several pressure holes 93 are opened at the bottom of the conical mesh 4. The pressure holes 93 are all connected to the water pressure groove at the bottom of the conical mesh 4. Four small magnets 94 are connected to the bottom of the conical mesh 4 by bolts. The small magnets 94 and the bottom of the conical mesh 4 are in contact with the bottom of the support frame 92. The small magnets 94 will attract the bottom of the support frame 92.
[0042] When the conical mesh 4 moves downward under the action of gravity, the water flow will enter the water-pressing groove at the bottom of the conical mesh 4, and then the water flow will be ejected through the pressurizing hole 93 on the water-pressurizing groove at the bottom of the conical mesh 4. The bottom of the support frame 92 will disengage from the small magnet 94. The water flow will push the support frame 92 and the horizontal rotating shaft 91 to swing upward to a suitable angle, thereby supporting the shell 1, the connecting frame 2, the conical shell 3, and the conical mesh 4. When the hollow line 71 moves upward and causes the conical mesh 4, the horizontal rotating shaft 91, the support frame 92, the pressurizing hole 93, and the small magnet 94 to all leave the water surface, the water flow will no longer push the support frame 92. The horizontal rotating shaft 91 and the support frame 92 will swing downward to reset under the action of gravity. The bottom of the support frame 92 and the small magnet 94 will re-contact the bottom of the conical mesh 4, and the small magnet 94 will re-attract the support frame 92. In this way, the shell 1, hollow tube 11, connecting frame 2, conical shell 3 and conical net 4 can remain more stable and vertical after sinking to the bottom of the water, which facilitates more stable hydrological surveys.
[0043] Example 3
[0044] Based on Example 2, such as Figures 11-14 As shown, it also includes a hollow cone 10, the top of the housing 1 is connected to the hollow cone 10 by bolts, and the hollow tube 11 passes through the hollow cone 10.
[0045] When the shell 1, hollow tube 11, connecting frame 2, conical shell 3 and conical mesh 4 are submerged in water, the hollow cone 10 can increase the buoyancy of the shell 1 in the water, thereby making the shell 1, hollow tube 11, connecting frame 2, conical shell 3 and conical mesh 4 more stable and vertical after sinking to the bottom of the water, and further making hydrological surveys more stable.
