Description

Technical Field

[0001] The present invention relates to the field of water conservancy measurement, and more specifically, to an intelligent water depth measurement device and method for water conservancy projects. Background Art

[0002] Water conservancy projects are constructed to control and allocate surface water and groundwater in nature to achieve the purposes of eliminating disasters and bringing benefits. In modern society, as an integral part of the national economic system, water conservancy projects have a special and important status in China and play a fundamental role in flood prevention and safety guarantee, supporting economic and social development, and maintaining the health of natural ecology.

[0003] During the design and construction of water conservancy projects, it is necessary to measure the water depth of their waters. The existing modern intelligent water depth measurement methods mainly include single-beam echo sounding, multi-beam echo sounding, and airborne laser sounding, etc. For single-beam echo sounding, its principle is to measure the time interval from the ultrasonic signal emitted by the transducer to the bottom of the water and then reflected back to the receiver, and then calculate the water depth based on the time interval and the propagation speed of sound waves in water.

[0004] In single-beam echo sounding equipment, its ultrasonic transmitting transducer and receiving transducer are both installed at the bottom of the ship. During use, since the surface of the transducer cannot be coated with paint, the transducer will gradually be corroded by water bodies and attached with shellfish and snails, affecting the service life and performance of the transducer (the attachment of shellfish and snails will cause the attenuation of sound waves and result in inaccurate measurement results). Therefore, it is necessary to regularly overhaul and maintain it. In the prior art, the replacement and overhaul of the transducer at the bottom of the ship can only be carried out when the whole ship enters the shipyard for overhaul. However, the ship overhaul period is relatively long, usually 2 - 3 years, and the overhaul frequency is low, which is not sufficient to ensure the replacement and overhaul period of the transducer. Therefore, during the navigation of the ship, its overhaul, maintenance, and replacement work will become very difficult.

[0005] Therefore, an intelligent water depth measurement device and method for water conservancy projects are proposed. Summary of the Invention

[0006] 1. Technical Problems to be Solved

[0007] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an intelligent water depth measurement device and method for water conservancy projects.

[0045] Embodiment 1:

[0046] Please refer to Figures 1 to 8 , an intelligent water depth measuring device for water conservancy projects, including a mounting plate 1,

[0047] The middle position on the upper surface of the mounting plate 1 is fixedly connected with a mounting member 2; a wire harness tube 3 is arranged at the middle position inside the mounting member 2; an anti-shellfish adsorption mechanism 4 is arranged at the edge position of the lower surface of the mounting plate 1; a sealed cabin 6 is fixedly installed at one side position of the lower surface of the mounting plate 1; a trigger pulse generator 11 is arranged inside the sealed cabin 6; an anti-rust mechanism 8 is fixedly connected to the lower end of the sealed cabin 6; a device cabin 10 is fixedly connected to one side surface of the outer surface of the anti-rust mechanism 8;

[0048] The anti-rust mechanism 8 includes a working cabin body 81 fixedly connected to the lower surface of the sealed cabin 6; a water suction pipe 82 is arranged inside the working cabin body 81; a water suction pump 84 is fixedly connected to one side wall of the inner wall of the device cabin 10; one end of the water suction pipe 82 penetrates through the side walls of the working cabin body 81 and the device cabin 10 and is communicated with the water suction pump 84; one end of the water suction pump 84 is fixedly connected with a drain pipe 85; one end of the drain pipe 85 extends outside the device cabin 10, and a one-way valve is arranged inside the drain pipe 85; a sealed plate opening and closing mechanism 83 is arranged at the inner bottom of the device cabin 10, and one end of the sealed plate opening and closing mechanism 83 penetrates through the side wall of the device cabin 10 and is rotatably connected with the working cabin body 81;

[0049] A transmitting transducer 12 and a receiving transducer 13 are arranged from left to right at the inner top of the working cabin body 81.

[0050] In view of the problem that the overhaul cycle of the ship's hull in the prior art is relatively long and the overhaul frequency is relatively low, which is insufficient to ensure the replacement and overhaul cycle of the transducer. Therefore, during the navigation of the ship, the overhaul, maintenance and replacement work will become very difficult. The present invention solves this problem by setting an anti-rust mechanism 8. When in use, first, the closed plate opening and closing mechanism 83 is closed, so that the internal space of the working cabin 81 is sealed. Then, the water pump 84 pumps out the water inside the working cabin 81 through the water suction pipe 82 and the drain pipe 85, so that the transmitting transducer 12 and the receiving transducer 13 inside the working cabin 81 are prevented from being soaked by water, thereby delaying their rusting speed, extending their overhaul cycle, reducing their overhaul frequency, making it consistent with the ship's hull overhaul cycle, and thus being able to meet the requirements of overhauling, maintaining and replacing the transmitting transducer 12 and the receiving transducer 13 during the ship's hull overhaul.

[0051] As an embodiment of the present invention, as Figure 2 and Figure 3 shown, the closed plate opening and closing mechanism 83 includes a motor 831 arranged on one side inside the equipment cabin 10; the output end of the motor 831 is fixedly connected with a speed reduction mechanism 832; one end of the speed reduction mechanism 832 is fixedly connected with a sealing bearing 836; one end of the sealing bearing 836 is rotatably connected with a closed plate 833; a sealing mechanism 835 is arranged around the outer surface of the closed plate 833; the middle position of the outer surface on one side of the closed plate 833 is also rotatably connected with the side wall of the working cabin 81 through a sealing bearing 836; a liquid level sensor 86 is arranged on the inner surface of one side of the working cabin 81.

[0052] As Figure 4 shown, the speed reduction mechanism 832 includes a worm 8321 fixedly connected with the output end of the motor 831; the lower surface of the worm 8321 is meshed with a worm wheel 8324; the middle position of the outer surface on one side of the worm wheel 8324 is fixedly connected with a connecting rod 8323, and one end of the connecting rod 8323 is fixedly connected with the sealing bearing 836; a coupling 8322 is arranged on the outer cylindrical surface of the connecting rod 8323.

[0053] When the transmitting transducer 12 and the receiving transducer 13 are not in use, the rust prevention mechanism 8 is required to protect them. At this time, the sealing plate opening and closing mechanism 83 closes the interior of the working cabin 81. When the sealing plate opening and closing mechanism 83 is in use, first, the motor 831 starts to work under the control of the control system, driving the reduction mechanism 832 to start working. The reduction mechanism 832 is a transmission member composed of a group of worm wheels 8324 and a worm 8321. The worm 8321 is the driving member, forming a reduction system, which can reduce the transmission power of the output shaft of the motor 831, thereby reducing the deflection speed of the sealing plate 833. Driven by the motor 831, the sealing plate 833 starts to deflect, changing from a vertical state to a horizontal state, and then seals the bottom of the working cabin 81. Among them, both ends of the sealing plate 833 are rotatably connected to the side wall of the working cabin 81 through sealing bearings 836, which can ensure the sealing performance inside the working cabin 81. The liquid level sensor 86 can detect the liquid level inside the working cabin 81, facilitating the control system to control the water pump 84 to work accurately.

[0054] As an implementation manner of the present invention, as Figure 5 shown, the sealing mechanism 835 includes a mounting frame 8355 fixedly connected to the outer surface of the sealing plate 833 for one week, and a waterproof bonding layer 8356 is provided between the sealing plate 833 and the mounting frame 8355; a support body 8353 is fixedly connected to the outer surface of one side of the mounting frame 8355; uniformly distributed rib plates 8352 are symmetrically installed on the outer side surface of the support body 8353; uniformly distributed support bars 8354 are provided inside the support body 8353; one end of the support body 8353 is fixedly connected to an arc-shaped sealing strip 8351; the arc-shaped sealing strip 8351, the rib plates 8352 and the support body 8353 are all components made of rubber material.

[0055] When the sealing plate opening and closing mechanism 83 uses the sealing plate 833 to seal the bottom of the working cabin 81, the sealing effect is poor, and water still enters through the gaps, making the rust prevention mechanism 8 unable to work. By providing the sealing mechanism 835 on the surface of the sealing plate 833 in contact with the working cabin 81 around the circumference, when the sealing plate 833 changes from a vertical state to a horizontal state, the arc-shaped sealing strip 8351 first contacts the side wall of the working cabin 81. After being pressed, it squeezes the support body 8353, and the support body 8353 deforms. At this time, there is pressure between the support body 8353 and the arc-shaped sealing strip 8351, which can completely seal the contact position between the sealing plate 833 and the working cabin 81 by the extrusion force, improving the sealing effect of the working cabin 81. In addition, the rib plates 8352 can improve the structural strength of the support body 8353 to prevent it from being damaged due to excessive extrusion. At the same time, the arc-shaped sealing strip 8351, the rib plates 8352 and the support body 8353 are all components made of rubber material, which have a good rust prevention effect while playing a sealing role and have a long service life.

[0056] AsFigure 2 and Figure 3 As shown in Figure 3 , a level sensor 834 is provided at the middle position of the upper surface of the sealed plate 833, and the level sensor 834 is of a waterproof type; a single-chip microcomputer 837 is provided at a position on one side of the sealed cabin 6 close to the trigger pulse generator 11.

[0057] When the rust prevention mechanism 8 uses the sealed plate opening and closing mechanism 83 to close the working cabin 81, it is difficult to master the horizontal state of the sealed plate 833, and the accuracy of the motor 831 in controlling deflection is low. By providing a level sensor 834 at the middle position of the upper surface of the sealed plate 833, through the detection of the level sensor 834, the single-chip microcomputer 837 can accurately sense the rotation state of the sealed plate 833, and then can accurately control the deflection of the motor 831, improving the working accuracy.

[0058] As an embodiment of the present invention, as Figure 1 and Figure 2 shown in Figure 2 , the anti-shellfish adsorption mechanism 4 includes an anti-attachment side net 41 fixedly connected to the edge position of the lower surface of the mounting plate 1; a bottom anti-attachment mechanism 9 is provided at the bottom of the equipment cabin 10; a shellfish removal mechanism 42 is fixedly connected in a U shape at a position on the outer side of the lower surface of the mounting plate 1 close to the anti-attachment side net 41; a protection mechanism 43 is fixedly connected at a position on the outer side of the lower surface of the mounting plate 1 close to the shellfish removal mechanism 42.

[0059] When the water depth measuring device works in the water body, shellfish and snails in the water will adsorb on the working surfaces of the transmitting transducer 12 and the receiving transducer 13. Since the working surfaces of the transmitting transducer 12 and the receiving transducer 13 have strong absorption of sound waves by paint, paint cannot be coated. At this time, the adsorption of shellfish and snails on the working surfaces of the transmitting transducer 12 and the receiving transducer 13 will attenuate the ultrasonic waves, reducing the measurement accuracy. In the present invention, although the transmitting transducer 12 and the receiving transducer 13 are sealed by providing the working cabin 81, however, when the working cabin 81 is adsorbed by shellfish and snails, it will be quickly corroded due to the mucus secreted by them, greatly reducing the service life of the working cabin 81. Therefore, by providing the anti-shellfish adsorption mechanism 4, by providing a circle of anti-attachment side nets 41 outside the working cabin 81, the sealed cabin 6 and the equipment cabin 10, and cooperating with the bottom anti-attachment mechanism 9 at the bottom, the working cabin 81, the sealed cabin 6 and the equipment cabin 10 can be protected, reducing their corrosion speed and extending the maintenance period. In addition, by providing the shellfish removal mechanism 42, the snails and shellfish adsorbed on the anti-attachment side net 41 can also be removed, further ensuring their service life.

[0060] As an embodiment of the present invention, as Figure 2 and Figure 3As shown in the figure, the bottom anti - adhesion mechanism 9 includes a rotating shaft 91 disposed inside the equipment cabin 10 and fixedly connected to the middle position of the outer surface of the other side of the worm gear 8324; one end of the rotating shaft 91 is fixedly connected to a gear 92; a rack 93 is meshed and connected to one side of the gear 92; the lower end of the rack 93 is fixedly connected to a push rod 94, and the push rod 94 extends to the outside of the equipment cabin 10, and a sealing ring is provided at the connection position between the push rod 94 and the equipment cabin 10; two fixing plates 95 are symmetrically installed on one side of the lower surface of the equipment cabin 10; one side of the two fixing plates 95 is jointly rotatably connected to the bottom anti - adhesion net 96.

[0061] When the bottom anti - adhesion mechanism 9 is in use, it works synchronously with the sealing plate opening and closing mechanism 83. When the motor 831 drives the worm gear 8324 to rotate, the rotating shaft 91 fixedly connected to the other end of the worm gear 8324 rotates, driving the gear 92 to rotate in the same direction as the worm gear 8324, and the rack 93 meshed with the gear 92 drives the push rod 94 to move up and down. By setting the operating direction of the motor 831, when the sealing plate 833 is converted from a horizontal state to a vertical state, the rack 93 drives the push rod 94 to move upward. When the water depth measuring equipment is in use, after the push rod 94 is removed, since one end of the bottom anti - adhesion net 96 is no longer pressed by the push rod 94, under the action of gravity, it deflects around the fixing plate 95, causing the bottom anti - adhesion net 96 to open. By driving the sealing plate opening and closing mechanism 83 and the bottom anti - adhesion mechanism 9 to work simultaneously by the motor 831, the bottom anti - adhesion mechanism 9 and the sealing plate opening and closing mechanism 83 can work synchronously, thereby improving work efficiency.

[0062] As an embodiment of the present invention, as Figure 6 shown in the figure, the shellfish removing mechanism 42 includes a high - pressure plunger pump 421 disposed at the upper end of the equipment cabin 10; one end of the high - pressure plunger pump 421 is fixedly connected to a connecting hose 422; one end of the connecting hose 422 extends to the outside of the equipment cabin 10 and is connected to a U - shaped pipe 423; the upper end of the U - shaped pipe 423 is provided with uniformly distributed telescopic rods 424, and the upper ends of the telescopic rods 424 are fixedly connected to the lower surface of the mounting plate 1; the lower end of the U - shaped pipe 423 is provided with uniformly distributed high - pressure nozzles 425, and the high - pressure nozzles 425 are inclined.

[0063] After the anti - adhesion side net 41 on the anti - shellfish adsorption mechanism 4 has been used for a long time, the surface will be covered with a large number of snails and shellfish. Under the action of corrosion, the service life of the anti - adhesion side net 41 is relatively short. By setting the shellfish removing mechanism 42, when working, the high - pressure plunger pump 421 sucks water and pressurizes it, and then sprays it out through the connecting hose 422, the U - shaped pipe 423 and the high - pressure nozzles 425 to remove the adsorbed snails and shellfish. The telescopic rods 424 can drive the U - shaped pipe 423 and the high - pressure nozzles 425 to move up and down, increasing the cleaning area.

[0064] As an embodiment of the present invention, as Figure 7 shown, the protection mechanism 43 includes a U-shaped side plate 431 fixedly connected to the lower surface of the mounting plate 1 near the outer side of the shellfish removal mechanism 42; an elastic sealing strip 432 is provided at the bottom end of the U-shaped side plate 431, and the elastic sealing strip 432 is of a hollow structure; a torsion spring 433 is fixedly connected inside the elastic sealing strip 432; one end of the torsion spring 433 is fixedly connected to a partition plate 434, and one end of the partition plate 434 extends outside the elastic sealing strip 432; a limiting strip 435 is fixedly connected to the outer surface of one side of the anti-adhesion side net 41 corresponding to the position of the elastic sealing strip 432.

[0065] When the shellfish removal mechanism 42 is not in use, its surface is also prone to adsorbing snails and shellfish, causing pipeline corrosion. By setting the protection mechanism 43, when the shellfish removal mechanism 42 is not in use, the telescopic rod 424 shortens, driving the U-shaped pipe 423 to return to the inside of the U-shaped side plate 431 by the high-pressure nozzle 425. At the same time, under the action of the torsion spring 433 and the limiting strip 435, the partition plate 434 turns to a horizontal state to close the U-shaped side plate 431, which can prevent snails and shellfish from adsorbing on the high-pressure nozzle 425 behind the U-shaped pipe 423. The torsion spring 433 is arranged in the elastic sealing strip 432 and can be protected from corrosion by water.

[0066] An intelligent water conservancy project water depth measurement method includes the following steps:

[0067] S1: Install the water depth measurement device on the bottom of the measurement ship by using the mounting plate 1 and the mounting parts 2;

[0068] S2: On the basis of S1, open the bottom anti-adhesion mechanism 9 and the closed plate opening and closing mechanism 83 to expose the transmitting transducer 12 and the receiving transducer 13 inside the working cabin 81;

[0069] S3: When performing water depth detection, control the trigger pulser 11 to work through the display control system on the measurement ship. The trigger pulser 11 emits ultrasonic pulses of a certain frequency to the bottom of the water through the transmitting transducer 12. After being reflected by the bottom ground, the ultrasonic waves are received by the receiving transducer 13 and the signals are transmitted to the display control system on the measurement ship;

[0070] S4: The display control system can calculate the water depth according to the time difference between the emission and reception of the pulsed sound wave and the sound velocity of the sound wave in the water body;

[0071] S5: When not in use, close the bottom anti-adhesion mechanism 9 and the closed plate opening and closing mechanism 83. The anti-shellfish adsorption mechanism 4 can prevent shellfish from adsorbing on the working surfaces of the transmitting transducer 12 and the receiving transducer 13, while the rust prevention mechanism 8 can drain the water inside the working cabin 81 where the transmitting transducer 12 and the receiving transducer 13 are located, so that the transmitting transducer 12 and the receiving transducer 13 are in a non-immersed state, delaying their rusting speed.

[0072] Usage method: When the present invention is in use, first, the water depth measuring device is installed at the bottom of the measuring ship by using the mounting plate 1 and the mounting member 2; the bottom anti-adhesion mechanism 9 and the closed plate opening and closing mechanism 83 are opened to expose the transmitting transducer 12 and the receiving transducer 13 inside the working cabin 81; when performing water depth detection, the trigger pulser 11 is controlled to work through the display control system on the measuring ship. The trigger pulser 11 emits ultrasonic pulses of a certain frequency to the bottom of the water through the transmitting transducer 12. After being reflected by the bottom ground, the ultrasonic waves are received by the receiving transducer 13 and the signals are transmitted to the display control system on the measuring ship; the display control system can calculate the water depth according to the time difference between the emission and reception of the pulsed sound waves and the sound velocity of the sound waves in the water body; when not in use, the bottom anti-adhesion mechanism 9 and the closed plate opening and closing mechanism 83 are closed, and the anti-shellfish adsorption mechanism 4 can prevent shellfish from adsorbing on the working surfaces of the transmitting transducer 12 and the receiving transducer 13, while the rust prevention mechanism 8 can drain the water inside the working cabin 81 where the transmitting transducer 12 and the receiving transducer 13 are located, so that the transmitting transducer 12 and the receiving transducer 13 are in a non-immersed state, delaying their rusting speed.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
