[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. For the portable water measuring device for water conservancy projects and its using method, after the limiting slider is snapped and fixed on the top of the main floating beam, select an appropriate amount of independent floating beams, and complete the assembly with the main floating beam and the counterweight floating beam, so that the main floating beam, independent floating beams and counterweight floating beam form a floating rod with a length corresponding to the measuring position.

[0022] 2. For the portable water measurement device of this water conservancy project and its usage method, when the top frame sinks in water, control the electromagnet to be energized to adsorb the metal plate, so that the metal plate drives the spring to move towards the electromagnet and compress the spring.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Embodiment 1:

[0036] Please refer to Figures 1-10 , a portable water measuring device for water conservancy projects, including a main floating beam 1 and a controller. The water measuring device is controlled by the controller. A main screw rod 11 is fixed on one side of the main floating beam 1. An independent floating beam 12 is threadedly connected to the outside of the main screw rod 11. An auxiliary screw rod 13 is fixed on the side of the independent floating beam 12 away from the main screw rod 11. A counterweight floating beam 14 is threadedly connected to the outside of the auxiliary screw rod 13;

[0037] A limit slider 2 is fixed to the outside of the main floating beam 1 by bolts. A floating plate 21 is fixed to the bottom of the limit slider 2. A bracket 22 is fixed to one side of the top of the floating plate 21. A motor 23 is fixed to the surface of the bracket 22. The bottom of the limit slider 2 is rotatably connected to a reel 24. One end of the reel 24 is fixed to the output shaft of the motor 23. A suspension rope 25 is wound around the outside of the reel 24. The suspension rope 25 passes through the floating plate 21. One end of the suspension rope 25 passing through the floating plate 21 is provided with a water measuring assembly for measuring water. A counterweight assembly is provided on the water measuring assembly for assisting the water measuring assembly to quickly enter the water;

[0038] The water measuring assembly includes a top frame 3, the top frame 3 is fixed to a suspension rope 25, a vertical rod 31 is fixed to the bottom of the top frame 3, a loading column 32 is fixed to the bottom of the vertical rod 31, a pressure type depth sensor 33 is fixed to the middle position at the bottom of the loading column 32, a conical wire mesh frame 34 is fixed to the bottom of the loading column 32, and the pressure type depth sensor 33 is located inside the conical wire mesh frame 34. The counterweight assembly includes a conical sleeve ring 4, the conical sleeve ring 4 is fixed to the outside of the loading column 32, two sides at the bottom of the inner cavity of the conical sleeve ring 4 are fixed with air cylinders 41, an annular rubber plate 42 is slidably and sealingly connected inside the conical sleeve ring 4, and the annular rubber plate 42 is fixed to the output shaft of the air cylinder 41. A water injection port 43 is opened at the top of the conical sleeve ring 4;

[0039] During the specific operation process, first, the limiting slider 2 is slidably sleeved outside the main floating beam 1, and the limiting slider 2 is fixed to the outside of the main floating beam 1 through bolts. Subsequently, according to the position where the water body needs to be measured, an appropriate amount of independent floating beams 12 are selected. Then, the first independent floating beam 12 is threadedly connected to the main screw rod 11, and the subsequent independent floating beams 12 are threadedly connected to the auxiliary screw rod 13 of the first independent floating beam 12 for assembly in sequence. After all the independent floating beams 12 are assembled, the counterweight floating beam 14 is threadedly connected to the auxiliary screw rod 13 of the last independent floating beam 12, thereby making the main floating beam 1, the main screw rod 11, the counterweight floating beam 14, and each independent floating beam 12 and auxiliary screw rod 13 form a whole;

[0040] When the present invention is assembled from individual components into a whole, the main floating beam 1 can be placed into the water surface, and by pushing and adjusting the counterweight floating beam 14, the counterweight floating beam 14 drives the independent floating beam 12 and the main floating beam 1 to perform displacement adjustment on the water surface, so that the main floating beam 1 drives the limiting slider 2 to be adjusted on the water surface until the limiting slider 2 moves to the position where measurement is required;

[0041] Specifically, when the limiting slider 2 moves to the specified position, the controller can be used to control the air cylinder 41 to reset. During the reset process of the air cylinder 41, it drives the annular rubber plate 42 to move towards the direction of the air cylinder 41, and then the water injection port 43 loses the sealing and shielding of the annular rubber plate 42. Since the water injection port 43 is located in the water body, when the water injection port 43 is completely opened, under the action of water pressure, the water body is poured into the inside of the conical sleeve ring 4 from the water injection port 43, increasing the weight of the conical sleeve ring 4, and then increasing the weight of the top frame 3, further increasing the sinking speed of the top frame 3 in the water, reducing the influence of water flow on the top frame 3, and further improving the accuracy of the sinking position of the top frame 3, and then improving the accuracy of the pressure type depth sensor 33 for measuring the water depth;

[0042] Subsequently, the motor 23 is started by the controller, causing the motor 23 to drive the reel 24 to rotate. During the rotation of the reel 24, the lifting rope 25 is released. After the release, the lifting rope 25, under the action of the gravity of the top frame 3, follows the top frame 3 and sinks into the water. When the top frame 3 sinks into the water, the pressure type depth sensor 33 can be started by the controller. When the pressure type depth sensor 33 sinks with the top frame 3, a water pressure test can be carried out, and the real-time water depth can be calculated based on the water pressure. When the water pressure no longer changes, it means that the pressure type depth sensor 33 has reached the bottom of the water. Subsequently, the calculation and measurement of the water depth can be carried out, and the measured data can be transmitted to the display for display.

[0043] It should be noted that during actual use, a display can be equipped for the pressure type depth sensor 33 to display the data measured by the pressure type depth sensor 33. The initial state of the air cylinder 41 is the ejected state, that is, the air cylinder 41 drives the annular rubber plate 42 to be in the ejected state, and then the initial state of the annular rubber plate 42 is to seal and cover the water injection port 43, making the water injection port 43 in a closed state;

[0044] According to Figure 3 As shown, the bottoms of the main floating beam 1 and the counterweight floating beam 14 are flat, and the bottom materials of the main floating beam 1 and the counterweight floating beam 14 can be made of plastic. Then, the main floating beam 1 and the counterweight floating beam 14 have considerable buoyancy on the water surface. At the same time, the bottom heights of the main floating beam 1 and the counterweight floating beam 14 are the same as the bottom height of the floating plate 21. Then, when the main floating beam 1 and the counterweight floating beam 14 float on the water surface, the floating plate 21 floats on the water surface synchronously, and then the top frame 3 is located in the water body below the floating plate 21. Therefore, when the water injection port 43 loses its sealing and covering, the water body can directly pour into the inside of the conical sleeve 4, improving the speed of adjusting the counterweight of the conical sleeve 4.

[0045] Embodiment 2:

[0046] A plurality of sleeves 5 are uniformly fixed at the bottom of the conical sleeve 4, and the sleeves 5 are communicated with the conical sleeve 4. Inner rods 51 are slidably and sealingly connected inside the sleeves 5. One side of the top of the inner rod 51 is fixed with a metal plate 52. A plurality of electromagnets 53 are fixed at the bottom of the annular rubber plate 42, and the positions and quantities of the electromagnets 53 correspond to those of the metal plate 52. An internal groove 54 is opened at the top end of the inner rod 51, a spring 55 is fixed at the bottom of the internal groove 54, and a telescopic groove 56 is opened inside the bottom end of the inner rod 51. An anchor head 57 is slidably and sealingly connected inside the telescopic groove 56;

[0047] An inner chute 6 is provided inside the inner rod 51, and both ends of the inner chute 6 communicate with the built-in groove 54 and the telescopic groove 56 respectively. A top rod 61 is slidably and sealingly connected inside the inner chute 6. The top of the top rod 61 is fixed to the annular rubber plate 42. An extension rod 62 is fixed to the top of the anchor head 57, and the extension rod 62 is slidably and sealingly connected with the inner chute 6. One side of the bottom end of the inner rod 51 is fixed with a side pipe 63. An air cavity 64 is provided inside the side pipe 63 near one end of the inner rod 51, and the air cavity 64 communicates with the telescopic groove 56. An anchor nail 65 is slidably and sealingly connected inside the air cavity 64, and the anchor nail 65 is slidably and sealingly connected with the side pipe 63. The anchor nail 65 and the extension rod 62 are connected by a connecting rope 66;

[0048] Specifically, on the basis of Embodiment 1, when the inside of the conical sleeve ring 4 is filled with water and during the sinking process of the top frame 3, the electromagnet 53 can be started through the controller. After the electromagnet 53 is powered on, it generates a suction force, so that the electromagnet 53 adsorbs the metal plate 52, causing the metal plate 52 to drive the inner rod 51 to move towards the direction of the electromagnet 53. The inner rod 51 drives the spring 55 to move towards the direction of the electromagnet 53, and the spring 55 is limited by the annular rubber plate 42, so that the spring 55 is compressed. At the same time, the inner rod 51 drives the anchor head 57 and the extension rod 62 to move towards the direction of the electromagnet 53. During the movement, the anchor head 57 and the extension rod 62 gradually approach the top rod 61 until they contact the top rod 61;

[0049] Since the top rod 61 is fixed to the annular rubber plate 42, and the annular rubber plate 42 is limited by the air cylinder 41 and is in a fixed state. That is, after the extension rod 62 contacts the top rod 61, the top rod 61 reversely pushes the extension rod 62, causing the extension rod 62 to push the anchor head 57 to move inside the telescopic groove 56, so that the anchor head 57 extends out from the telescopic groove 56. During the process of the top rod 61 pushing the extension rod 62, the extension rod 62 pulls the connecting rope 66 to move towards the direction of the anchor head 57, and then the connecting rope 66 pulls the anchor nail 65 to slide inside the air cavity 64 and the side pipe 63, so that the anchor nail 65 is retracted into the side pipe 63;

[0050] When the pressure type depth sensor 33 reaches the bottom of the water, that is, the conical wire frame 34 reaches the bottom of the water synchronously and contacts the bottom soil. When the conical wire frame 34 reaches the bottom of the water, the electromagnet 53 can be controlled to be powered off, so that the electromagnet 53 loses its adsorption on the metal plate 52, and then the spring 55 loses pressure and resets. During the reset process of the spring 55, it drives the inner rod 51 to eject and reset. During the reset process of the inner rod 51, it ejects towards the direction of the bottom soil;

[0051] During the ejection process of the inner rod 51, the inner rod 51 drives the anchor head 57 to synchronously eject towards the bottom soil. The ejector rod 61 gradually disengages from the inner chute 6, increasing the space inside the inner chute 6. When the anchor head 57 contacts the bottom soil, the anchor head 57 and the inner rod 51 are anchored into the bottom soil. Thus, under the action of each anchored anchor head 57 and inner rod 51, the stability of the top frame 3 and the conical collar 4 after sinking to the bottom of the water is increased, and the situation of deviation caused by the impact of water flow on the top frame 3 is also avoided, ensuring the accuracy of the later water depth measurement;

[0052] Furthermore, at the moment when the anchor head 57 is anchored into the bottom soil, under the reaction force of the bottom soil, the anchor head 57 is retracted into the inside of the telescopic groove 56 again. After the anchor head 57 is retracted into the inside of the telescopic groove 56, the anchor head 57 compresses the air in the telescopic groove 56, increasing the air pressure in the telescopic groove 56 and the air chamber 64. The air pressure pushes the anchor pin 65, causing the anchor pin 65 to protrude outward from the inside of the side pipe 63, and the anchor pin 65 is anchored into the bottom soil again at an inclined angle, further increasing the anchoring effect, making the top frame 3 and the conical collar 4 more stable, and thus improving the accuracy of the later pressure type depth sensor 33 for measuring the water depth.

[0053] It should be noted that the extension rod 62 is always in sliding and sealing connection with the inner chute 6, that is, the connection between the telescopic groove 56 and the inner chute 6 is sealed by the extension rod 62.

[0054] Embodiment Three:

[0055] A support plate 7 is fixed to the inner wall of the loading column 32. A waterproof pipe 701 is fixed to the top of the support plate 7, and the space between the waterproof pipe 701 at the top of the support plate 7 and the inner wall of the loading column 32 is used as a storage groove 702. A double-headed cylinder 71 is fixed inside the support plate 7, and the double-headed cylinder 71 is located inside the waterproof pipe 701. The top of the loading column 32 is rotatably connected to a steering frame 72. A limit rotating shaft 73 is fixed to the top of the steering frame 72, and the limit rotating shaft 73 is rotatably connected to the top frame 3. A detection port 74 is opened inside the limit rotating shaft 73. A storage chamber 75 is opened at the bottom of the detection port 74. A flow velocity sensor 76 is slidably connected inside the storage chamber 75. A linkage frame 77 is fixed to the bottom of the flow velocity sensor 76, and the linkage frame 77 is rotatably connected to the steering frame 72. The output shaft of the double-headed cylinder 71 close to the steering frame 72 is rotatably connected to the linkage frame 77;

[0056] The output shaft of the double-headed cylinder 71 near one end of the conical grid 34 is fixed with a cross plate 8. Four corners of the cross plate 8 near one side of the support plate 7 are fixed with rubber rods 81. The rubber rods 81 are slidably and sealingly connected to the support plate 7. A sealing ring 82 is fixed on the surface of the rubber rod 81. A plurality of water inlets 83 are evenly formed at the top of the loading column 32, and the number and positions of the water inlets 83 correspond to those of the rubber rods 81. The rubber rods 81 are slidably and sealingly connected to the water inlets 83. A plurality of water inlets 83 are evenly fixed on the side of the cross plate 8 away from the rubber rods 81, and the water inlets 83 pass through the pressure type depth sensor 33;

[0057] Specifically, on the basis of Embodiment 1 and Embodiment 2, when the pressure type depth sensor 33 sinks to the bottom and the inner rod 51, the anchor head 57 and the anchor pin 65 are respectively fixed to the ground, the top frame 3 tends to be in a stable state. At this time, the underwater water flow impacts the top frame 3 and impacts the swivel frame 72. According to Figure 4 , both sides of the swivel frame 72 are inclined. Therefore, after the swivel frame 72 is impacted by the water flow, it can turn along the water flow direction, so that the detection port 74 is in a relative state with the water flow, and then the water flow can enter the inside of the swivel frame 72 through the detection port 74;

[0058] At this time, the double-headed cylinder 71 can be started through the controller, so that the output shaft of the double-headed cylinder 71 near one end of the swivel frame 72 is ejected, so that the double-headed cylinder 71 drives the linkage frame 77 to be ejected, so that the linkage frame 77 drives the flow velocity sensor 76 to be ejected from the inside of the storage compartment 75, and then the water flow entering the swivel frame 72 passes through the flow velocity sensor 76. Furthermore, the flow velocity sensor 76 measures the flow velocity of the water flow and synchronously transmits the measured data to the display;

[0059] Furthermore, in Embodiment 1 and Embodiment 2, when the top frame 3 sinks, the double-headed cylinder 71 can be started through the controller, so that the output shaft of the double-headed cylinder 71 near one end of the pressure type depth sensor 33 is ejected, so that the double-headed cylinder 71 drives the cross plate 8 to move towards the pressure type depth sensor 33, and then the cross plate 8 drives the rubber rod 81 and the sealing ring 82 to move towards the pressure type depth sensor 33. During the movement of the rubber rod 81, it disengages from the inside of the water inlet 83, and the sealing ring 82 also releases the abutment with the water inlet 83, and then the water inlet 83 is opened, and then the water body enters the inside of the storage tank 702 from the water inlet 83, and then the weight of the top frame 3 is further increased, further increasing the sinking speed of the top frame 3, improving the resistance of the top frame 3 to the underwater undercurrent, and the stability of the top frame 3 after sinking to the bottom, reducing the probability of deviation, and improving the measurement accuracy of the pressure type depth sensor 33;

[0060] Furthermore, when the storage groove 702 is filled with water, the double-headed cylinder 71 can be reset. When the conical wire frame 34 contacts the bottom soil, the end of the double-headed cylinder 71 close to the pressure depth sensor 33 can be controlled to protrude again, so that the double-headed cylinder 71 drives the cross plate 8 to move towards the pressure depth sensor 33. The cross plate 8 synchronously drives the anchor rod 84 to move towards the bottom soil. And because the weight of the top frame 3 itself increases again, with the top frame 3 as the support, the anchor rod 84 is anchored into the bottom soil, thereby further increasing the stability of the top frame 3 and the conical collar 4 at the bottom of the water, and also improving the accuracy of the pressure depth sensor 33 and the flow velocity sensor 76 in measuring the water flow and the water body flow velocity;

[0061] After the measurement is completed, the cylinder 41 can be controlled by the controller to protrude, so that the cylinder 41 drives the annular rubber plate 42 to slide inside the conical collar 4, making the annular rubber plate 42 approach towards the water injection port 43. Then, the accumulated water in the conical collar 4 is discharged outwards through the annular rubber plate 42 until the annular rubber plate 42 abuts against the top of the inner cavity of the conical collar 4 to seal the water injection port 43. Thus, the weight of the top frame 3 and the conical collar 4 is reduced. Subsequently, the motor 23 is controlled to drive the reel 24 to reverse, so that the reel 24 winds up the suspension rope 25, and then the top frame 3 and the conical collar 4 are towed back from the bottom of the water.

[0062] It should be noted that when not in measurement, the flow velocity sensor 76 can be retracted inside the storage cabin 75, avoiding the friction of the gravel in the water flow on the flow velocity sensor 76 and improving the service life of the flow velocity sensor 76. At the same time, the pressure depth sensor 33 is located inside the conical wire frame 34. The conical wire frame 34 can provide protection for the pressure depth sensor 33, ensuring the normal measurement of the water pressure by the pressure depth sensor 33 while avoiding the touch of the bottom fish or debris on the pressure depth sensor 33, thereby improving the accuracy of the water pressure measurement of the pressure depth sensor 33, and then improving the accuracy of the subsequent calculation of the water depth. And the double-headed cylinder 71 is located inside the waterproof pipe 701, and the waterproof pipe 701 ensures that water does not contact the double-headed cylinder 71.

[0063] A method for using a portable water measurement device for water conservancy projects, using the portable water measurement device for water conservancy projects as described above, including the following steps:

[0064] A1: First, according to the measurement position of the water body to be measured, first slide and snap the limit slider 2 outside the main floating beam 1 and fix it with bolts. Then, select an appropriate amount of independent floating beams 12, and then splice the main floating beam 1, the independent floating beams 12 and the counterweight floating beam 14, so that the combination of the main floating beam 1, the independent floating beams 12 and the counterweight floating beam 14 can send the limit slider 2 to the designated water measurement location;

[0065] A2: Then start the motor 23 to drive the reel 24 to rotate, and release the lifting rope 25, so that the water measuring assembly sinks into the water body along with the released lifting rope 25. After the water measuring assembly is completely submerged in the water, the water in the water body is filled into the counterweight assembly through the counterweight assembly, so that the weight of the water measuring assembly increases and it quickly sinks to the bottom.

[0066] A3: After the water measuring assembly sinks to the bottom, it is anchored by the anchor head 57 and the anchor pin 65, and secondary anchored by the anchor rod 84, so that when the present invention is measuring at the bottom, displacement caused by water flow impact, pebble and fish impact, etc. can be avoided, and the measurement accuracy is improved.

[0067] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
