Description

Technical Field

[0001] The invention belongs to the technical field of ocean water quality detection spectrometers, in particular to an ocean water quality remote sensing monitoring spectrometer. Background Art

[0002] The working position of the ocean water quality remote sensing monitoring spectrometer is not limited to one place. In the air, the ocean water quality can be tested with the help of drones equipped with spectrometers. The drones are highly maneuverable and can flexibly reach designated sea areas to carry out work. In the water, buoys are common carrying platforms. The buoys float on the sea surface and drift with the current. The spectrometers installed on them can monitor the water quality parameters of the surrounding seawater in real time. This method can continuously monitor the ocean water quality at a specific location in situ for a long time, and continuously provide real-time data for marine environmental monitoring and early warning. Spectrometers operating underwater face many challenges brought by the seawater environment. The seawater flow rate is significantly uncontrollable. Fast-flowing water not only changes the water environment, but also affects the surrounding biological activities. When the water flow speed increases, it will drive the fish to move quickly. These fish are very likely to frequently shuttle around the lens of the spectrometer under the influence of the water flow. At present, the spectrometers located underwater in existing devices are generally not equipped with a function specifically for dispersing fish. This leads to the frequent appearance of fish near the lens during actual operation, which may cause a series of problems. On the one hand, the huge body or dense swimming of the fish can easily block the lens of the spectrometer, making it impossible for the spectrometer to normally obtain the light information of the target sea area, thereby extending the measurement data cycle and failing to provide real-time data support for marine environmental monitoring in a timely manner. On the other hand, when the fish swim quickly, there is a risk of hitting the lens. Once a collision occurs, it may cause damage such as scratches on the lens surface and displacement of internal optical components, seriously affecting the optical performance of the spectrometer, and ultimately causing the accuracy of its measurement data to deteriorate significantly, causing deviations in the monitoring results and failing to accurately reflect the true condition of the marine water quality. Summary of the invention

[0003] In order to solve the problems raised in the above background technology, the present invention provides a remote sensing monitoring spectrometer for ocean water quality, comprising a float, a placement bucket for placing a driving liquid, an emergency feeding structure located above the placement bucket, and a dispersing structure located below the placement bucket are installed on the top of the float, a spectrometer body is installed at the axis of the bottom of the float, and a protective structure is arranged outside the spectrometer body, a controller body is installed behind the placement bucket, and a protective cover is arranged outside the float; The emergency feeding structure includes an emergency box installed on the top of the placement barrel and a cylinder installed on the top of the emergency box, and a gear plate fixedly connected to the output end of the cylinder. The outer part of the gear plate is meshed and connected with two symmetrically distributed gears, and the bottom of the gear passes through the placement barrel and is equipped with a blocking ring; The dispersing structure includes two symmetrically distributed servo motors installed on both sides of the placement barrel, two cavities opened inside the float, and an output box installed below the cavity. The output ends of the two servo motors are both installed with cylinders, the outer walls of the cylinders are opened with guide grooves, and the inside of the guide grooves is slidably connected with movable blocks.

[0004] Preferably, two symmetrically distributed sliding rods are installed on the inner top wall of the cavity, a spring is sleeved on the outside of the sliding rod, and the bottom of the movable block is fixedly connected to the top of the spring.

[0005] Preferably, there are two connecting rods at the bottom of the movable block and located in the middle of the two sliding rods. The bottom of the connecting rods penetrates the output box and is equipped with a piston plate that fits the inner wall of the output box.

[0006] Preferably, the outsides of the two output boxes are connected with a transmission pipe and the other end of the transmission pipe is connected with the placement bucket, and a spray head connected with the output box is installed at the bottom.

[0007] Preferably, the protective structure includes a bidirectional threaded rod and two protective covers threadedly connected to the outside of the bidirectional threaded rod, extension rods are provided at both ends of the bidirectional threaded rod and a water wheel is fixedly installed at one end of the extension rod away from the bidirectional threaded rod, and belts are provided on the outside of the two extension rods.

[0008] Preferably, the inner wall of the belt is rotatably connected to a pulley that fits tightly with the inner wall, and a driving motor is arranged above the float and behind the pulley.

[0009] Preferably, the inner wall of the emergency box is provided with two through holes communicating with the placement bucket, and a float type water level sensor is arranged inside the placement bucket.

[0010] Preferably, the float type water level sensor, the drive motor, the servo motor and the cylinder are all communicatively connected with the controller body.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention effectively realizes the evacuation of fish schools through the design of the dispersing structure, so that the measurement result is more accurate. The servo motor drives the cylinder to rotate. As the cylinder rotates, the movable block can only move up and down in the vertical direction under the constraint of the guide groove and the limiting effect of the slide rod. In the process of the movable block moving downward, it will gradually squeeze the spring below, so that the spring will produce elastic deformation and store elastic potential energy. At the same time, the movable block is connected to the piston plate through a connecting rod. When the movable block moves downward, the connecting rod will drive the piston plate to move downward synchronously in the output box. The output box is pre-filled with a special driving liquid. As the piston plate moves downward, the pressure in the output box gradually increases, and the driving liquid is sprayed from the spray head. Since the smell or components emitted by the driving liquid will stimulate the sense organs of the fish, the fish are prompted to avoid and be discharged, which effectively avoids the fish from blocking and impacting the spectrometer lens, and greatly improves the stability of the spectrometer measurement environment.

[0012] The present invention realizes effective replenishment of the driving liquid inside the placement barrel through the design of the emergency feeding structure, and conveniently and timely monitors the liquid in the placement barrel through the design of the float type water level sensor. When the liquid level is too low, the float type water level sensor transmits a signal to the controller, and the controller controls the cylinder to start, and the gear plate is pushed to move by the cylinder, and the gear plate can drive the gear to rotate, and the through hole is unsealed after the rotation of the gear and the blocking ring. At this time, the driving liquid pre-reserved in the emergency box, under the action of gravity and the pressure formed by the liquid level difference, flows into the placement barrel continuously along the discharge port to complete the replenishment of the driving liquid in the placement barrel, which greatly increases the sustainability of the dispersing structure and ensures that the spectrometer can always rely on sufficient driving liquid to effectively disperse the surrounding fish schools during long-term underwater operation, thereby ensuring its own stable operation.

[0013] The present invention realizes the protection of the spectrometer body through the design of the protection structure. When the wind and waves are strong, the fish and the waves will impact the spectrometer body. At this time, the two protective covers move closer to the middle and gradually close to protect the spectrometer body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figures 1 to 8 As shown, the present invention provides a remote sensing monitoring spectrometer for ocean water quality, comprising a float 1, a placement bucket 2 for placing a driving liquid, an emergency feeding structure 3 located above the placement bucket 2, and a dispersing structure 4 located below the placement bucket 2 are installed on the top of the float 1, a spectrometer body 5 is installed at the axis of the bottom surface of the float 1, and a protective structure 6 is arranged outside the spectrometer body 5, a controller body 7 is installed behind the placement bucket 2, and a protective cover 8 is arranged outside the float 1; The emergency feeding structure 3 includes an emergency box 31 installed on the top of the placement barrel 2, a cylinder 32 installed on the top of the emergency box 31, and a gear plate 33 fixedly connected to the output end of the cylinder 32. The outer part of the gear plate 33 is meshed and connected with two symmetrically distributed gears 34. The bottom of the gear 34 passes through the placement barrel 2 and is installed with a blocking ring 35. The dispersing structure 4 includes two symmetrically distributed servo motors 41 installed on both sides of the placement barrel 2, two cavities 42 opened inside the float 1, and an output box 43 installed below the cavity 42. The output ends of the two servo motors 41 are both equipped with cylinders 44, the outer wall of the cylinder 44 is provided with a guide groove 45, and the inside of the guide groove 45 is slidably connected with a movable block 46.

[0018] The above scheme is adopted: through the design of the dispersing structure 4, the evacuation of the fish school is effectively achieved, so that the measurement result is more accurate, and the servo motor 41 drives the cylinder 44 to rotate. As the cylinder 44 rotates, the movable block 46 can only move up and down in the vertical direction under the constraint of the guide groove 45 and the limiting effect of the slide bar 47. In the process of the movable block 46 moving downward, it will gradually squeeze the spring 471 below, so that the spring 471 produces elastic deformation and stores elastic potential energy. At the same time, the movable block 46 is connected to the piston plate 481 through the connecting rod 48. When the movable block 46 moves downward, the connecting rod 48 will drive the piston plate 481 to move downward synchronously in the output box 43. The output box 43 is pre-filled with a special driving liquid. As the piston plate 481 moves downward, the pressure in the output box 43 gradually increases, and the driving liquid is sprayed from the spray head 431 to the output box 431. The smell or ingredients emitted by the repelling liquid will stimulate the sense organs of fish, thereby prompting fish to avoid it, effectively avoiding the obstruction and impact of fish on the spectrometer lens, and greatly improving the stability of the spectrometer measurement environment. The repelling liquid mentioned in the article is mint extract, the smell or ingredients emitted by it will stimulate the sense organs of fish, causing fish to avoid it, and it is relatively easy to degrade in the natural environment. At normal usage concentrations, it will not have a significant effect on the optical properties of the water body, and will not interfere with the measurement of water quality parameters by the marine water quality remote sensing monitoring spectrometer. In order to reduce the excessive concentration of mint extract, when the servo motor 41 continues to rotate, the movable block 46 slides along the inside of the guide groove 45 and drives the revival plate to reset under the action of the elastic potential energy of the spring 471, thereby reducing the environmental pollution caused by excessive mint extract and the problem of affecting the detection structure.

[0019] like Figure 1 - Figure 8 As shown, two symmetrically distributed slide bars 47 are installed on the inner top wall of the cavity 42, and a spring 471 is sleeved on the outside of the slide bar 47. The bottom of the movable block 46 is fixedly connected to the top of the spring 471. There are two connecting rods 48 at the bottom of the movable block 46 and located in the middle of the two slide bars 47. The bottom of the connecting rod 48 passes through the output box 43 and is installed with a piston plate 481 that fits the inner wall of the output box 43. The outsides of the two output boxes 43 are connected with a transmission pipe 49 and the other end of the transmission pipe 49 is connected to the placement barrel 2. The bottom of the output box 43 is installed with a spray head 431 that is connected thereto.

[0020] The above scheme is adopted: through the design of the emergency feeding structure 3, the effective replenishment of the driving liquid inside the placement barrel 2 is realized, and through the design of the float type water level sensor 36, the liquid in the placement barrel 2 is conveniently and timely monitored. When the liquid level is too low, the float type water level sensor 36 transmits a signal to the controller, and the controller controls the cylinder 32 to start, and the gear plate 33 is pushed to move by the cylinder 32, and the gear plate 33 can drive the gear 34 to rotate, and the through hole is unsealed after the rotation of the gear 34 and the blocking ring 35. At this time, the driving liquid pre-reserved in the emergency box 31, under the action of gravity and the pressure formed by the liquid level difference, flows into the placement barrel 2 along the discharge port continuously, completing the replenishment of the driving liquid in the placement barrel 2, greatly increasing the sustainability of the dispersing structure 4, ensuring that the spectrometer can always rely on sufficient driving liquid to effectively disperse the surrounding fish schools during long-term underwater operations and ensure its own stable operation.

[0021] like Figure 1 - Figure 8 As shown, the protective structure 6 includes a bidirectional threaded rod 61 and two protective covers 62 threadedly connected to the outside of the bidirectional threaded rod 61, extension rods 63 are provided at both ends of the bidirectional threaded rod 61, and a water wheel 64 is fixedly installed at one end of the extension rod 63 away from the bidirectional threaded rod 61, and belts 65 are sleeved on the outside of the two extension rods 63, and the inner wall of the belt 65 is rotatably connected to a pulley 66 that fits tightly with the inner wall, and a driving motor 67 is arranged above the float 1 and behind the pulley 66.

[0022] The above scheme is adopted: through the design of the protection structure 6, the protection of the spectrometer body 5 is achieved. When the wind and waves are strong, the fish and the waves will impact the spectrometer body 5. At this time, the two protective covers 8 move closer to the middle and gradually close to achieve the protection of the spectrometer body 5. When the water flow rate in the ocean is too fast, the water wheel 64 will rotate, and an overload protector is arranged inside the water wheel 64. When the water wheel 64 rotates at high speed, the overload protector will transmit a Class A signal to the controller body 7, and the controller body 7 controls the drive motor 67 to start by receiving the Class A signal, and drives the bidirectional threaded rod 61 to rotate through the drive motor 67, thereby driving the two protective covers 62 to move toward the middle to protect the spectrometer body 5.

[0023] like Figure 1 - Figure 8 The inner wall of the emergency box 31 is provided with two through holes connected with the placement bucket 2. A float type water level sensor 36 is arranged inside the placement bucket 2. The float type water level sensor 36, the drive motor 67, the servo motor 41 and the cylinder 32 are all connected to the controller body 7 for communication.

[0024] The above scheme is adopted: the controller body 7 is the existing technology. When the level of the driving liquid in the placement bucket 2 drops to a preset low liquid level threshold, the float type water level sensor 36 will detect this change and generate a low liquid level signal, which is transmitted to the controller body 7 through a wire. After receiving the low liquid level signal, the controller body 7 identifies it as an instruction to replenish the driving liquid. The controller body 7 immediately sends a start signal to the cylinder 32. After receiving the signal, the cylinder 32 starts to work, pushing the gear plate 33 to move, thereby driving the gear 34 to rotate, releasing the seal on the through hole, and allowing the driving liquid in the emergency box 31 to flow into the placement bucket 2. When it is necessary to disperse the school of fish, the controller body 7 will send a start instruction to the servo motor 41 according to a preset time interval or an external trigger signal such as a spectrometer measurement. After receiving the start instruction, the servo motor 41 starts to rotate, driving the cylinder 44 to rotate. As the cylinder 44 rotates, the movable block 46 moves up and down in the vertical direction under the constraint of the guide groove 45 and the limiting action of the slide rod 47, and then pushes the piston plate 481 in the output through the connecting rod 48. The water wheel 64 moves out of the box 43 to release the driving liquid. When the water flow rate in the ocean is too fast, causing the water wheel 64 to rotate at a high speed, the overload protector inside the water wheel 64 will detect this change and generate a high-speed rotation signal, which is transmitted to the controller body 7 through a wire. After receiving the high-speed rotation signal, the controller body 7 identifies it as an instruction to protect the spectrometer body 5. The controller body 7 immediately sends a start signal to the drive motor 67. After receiving the signal, the drive motor 67 starts to work, driving the bidirectional threaded rod 61 to rotate, driving the two protective covers 62 to move toward the middle, closing the protective cover 8, and protecting the spectrometer body 5. All sensors including the float type water level sensor 36, the overload protector, etc. and the actuators including the drive motor 67, the servo motor 41, the cylinder 32, etc. are connected to the controller body 7 through the wireless communication module to ensure accurate transmission of signals and timely execution of instructions. A signal processing module and an instruction generation module are arranged inside the controller body 7 to process the received sensor signals and generate corresponding control instructions according to preset logical rules.

[0025] The working principle and use process of the present invention: First, place the float 1 in the designated monitoring sea area to ensure that it floats stably, inject an appropriate amount of mint extract into the placement barrel 2 as a repelling liquid, and check whether the repelling liquid stored in the emergency box 31 is sufficient. The spectrometer body 5 starts to work and monitors the ocean water quality in real time. If there is a school of fish approaching for interference, the operator starts the servo motor 41 through the controller body 7. The servo motor 41 drives the cylinder 44 to rotate, so that the movable block 46 moves up and down in the guide groove 45, squeezes the spring 471 and drives the piston plate 481 to move downward through the connecting rod 48, and the mint extract in the output box 43 is sprayed out from the spray head 431. To disperse the fish, the float type water level sensor 36 in the placement bucket 2 monitors the liquid level in real time. When the liquid level is too low, a signal is sent to the controller body 7. The controller body 7 controls the cylinder 32 to start, pushes the gear plate 33 to move, and drives the gear 34 and the blocking ring 35 to rotate. At this time, the driving liquid flows into the placement bucket 2 through the through hole. When the wind and waves are strong or the water flow rate is too fast, the water wheel 64 rotates, and its internal overload protector sends a Class A signal to the controller body 7. The controller body 7 controls the drive motor 67 to start, drives the bidirectional threaded rod 61 to rotate, and moves the two protective covers 62 to the middle to protect the spectrometer body 5.
