Description

Technical Field

[0001] The present invention relates to the fields of agricultural machinery automation and water environment detection such as fishery farming, and specifically to a multi-functional water quality detection device and method installed on an amphibious water-air vehicle. Technical Background

[0002] Water quality is of utmost importance in the aquaculture industry, and the quality of aquatic products is closely related to water quality. Existing water quality detection devices are basically handheld and fixed-point devices. Handheld devices require manual measurement, which is time-consuming and laborious; fixed-point devices can only detect the water quality of a single fish pond and cannot meet the needs of distributed intelligent fish ponds. Moreover, the devices need to be maintained regularly, and the replacement cost is high. Traditional water quality detection cannot detect the water quality of different water layers in fish ponds, lakes, etc., and the detection area is limited. In addition, in traditional aquaculture methods, farmers mainly collect water samples manually and analyze and adjust water quality detection parameters based on experience. This method is inefficient and has poor timeliness. Specifically, due to the lack of experience or inadequate detection by farmers, the water quality cannot be adjusted in time, which is not conducive to expanding the aquaculture scale and easily leads to poor quality or even death of aquatic products, resulting in economic losses.

[0003] Currently, the fishery farming industry is more committed to improving the efficiency and timeliness of water quality detection and pursuing more automated and intelligent water quality detection devices. Real-time detection of fish pond water quality can timely handle corresponding water quality problems according to the detection results, which is beneficial to improving the quality of aquatic products, increasing the production capacity of aquaculture, reducing labor costs, and increasing the economic income of farmers, thus gradually becoming the development direction of future aquaculture technology. Summary of the Invention

[0004] Based on the above deficiencies of the prior art, the present invention discloses a multi-functional water quality detection device based on an amphibious water-air vehicle. Different from the prior fixed-point water quality detection devices with limited detection ranges, during the detection of river pond water quality, the present invention can flexibly cross different areas through the amphibious water-air vehicle and more conveniently and efficiently collect water quality information of different waters.

[0005] Technical solution of the device of the present invention: A multifunctional water quality detection device based on an amphibious water-air vehicle, including a water pump bottom plate (1), a pump fixing pipe clamp (2), a carbon tube (3), a support carbon tube (4), a main control board (5), a driving servo (6), an aluminum part (7), a servo disc (8), a cable (9), a winding wheel (10), a three-way pipe (11), a main body carbon tube (12), a first joint three-way pipe (13), a first joint carbon tube (14), a fixing pipe clamp (15), a nozzle holder (16), a high-pressure nozzle (17), a water quality detection tube (18), a water pressure sensor (19), a base disc (20), an underwater rangefinder (21), a probe positioning cap (22), a second joint carbon tube (23), a water pump (24), a second joint three-way pipe (25), a joint pipe clamp (26), a bearing (27), a third joint carbon tube (28), a probe calibration capsule (29), a disc (30);

[0006] On one side in the horizontal direction of the main body carbon tube (12), two carbon tubes (3) connected by a three-way pipe are arranged. On one side in the vertical direction of the main body carbon tube (12), two first joint carbon tubes (14) and two second joint three-way pipes (25) connected by a three-way pipe are respectively arranged. The second joint three-way pipes (25) are inside the two first joint carbon tubes (14), and a second joint carbon tube (23) is connected between the second joint three-way pipes (25);

[0007] The water pump bottom plate (1) fixes the water pump (24) on the main body carbon tube (12) at the bottom of the amphibious water-air vehicle through the pump fixing pipe clamp (2), and a winding wheel (10) is assembled on the same side. One end of the winding wheel (10) is connected to the driving servo (6) through the servo disc (8), and the other end is joined to the carbon tube (3) through the bearing (27), and then connected to the third joint carbon tube (28), and fixed on the carbon tube (3) through the three-way pipe (11). The cable (9) is wound on the bearing (27), and the driving servo (6) is fixed with the aluminum part (7) and placed in the space supported by the two main control boards (5) through the support carbon tube (4);

[0008] The main body carbon tube (12) is connected and fixed to the first joint carbon tubes (14) on both sides through the first joint three-way pipe (13). The first joint carbon tube (14) is connected to the nozzle holder (16) through the fixing pipe clamp (15), and the high-pressure nozzle (17) is fixed under the nozzle holder (16);

[0009] The joint pipe clamp (26) fixes the second joint carbon tube (23) and the disc (30) together, and the probe positioning cap (22) is fixed by drilling holes on the surface of the above disc (30); The water quality detection tube (18) required for water quality detection operations can be assembled on the upper surface of the base disc (20), and the underwater rangefinder (21) and the water pressure sensor (19) are assembled on the lower surface of the base disc (20).

[0010] Further, the main control board (5) sends a control signal to control the driving servo (6) to drive the winding wheel (10) to rotate, thereby realizing the retraction and release of the cable (9), so as to achieve the purpose of putting the multifunctional water quality detection device to different water depths.

[0011] Further, the cable (9) is a long strip-shaped rigid waterproof wire. There is a protruding columnar body on the upper surface of the base disk (20). The columnar body is drilled through in the center to form a long strip-shaped channel for fixing the cable (9) and providing a channel for the cable (9) to pass through, so as to supply power to the underwater rangefinder (21) and the water pressure sensor (19).

[0012] Further, the high-pressure nozzle (16) is of a fan-shaped structure. A hole is drilled in the middle of the base disk (20) to facilitate the passage of the cable (9). The cable (9) communicates with the water quality detection tube (18) through the interlayer of the base disk (20).

[0013] Further, the probe calibration capsule (29) is made of rubber and contains a solution corresponding to the lower water quality detection tube (18) for calibrating and maintaining the water quality detection tube. The probe calibration capsule (29) opens downward and is usually in a closed and sealed state. After the water quality detection tube (18) is inserted, it performs function calibration and maintenance; the operator can select the water quality detection tube (18) for detecting different water quality parameters and install it on the base disk (20) to perform water quality detection operations.

[0014] Further, the underwater rangefinder (21) can measure the relative position between the bottom of the present invention and the underwater object in real time, flexibly command the operation of the water-air amphibious vehicle, and avoid obstacles in time. The water pressure sensor (19) can judge the current water depth, extract water layer information, and upload the water depth data of the river pond to the user terminal; after the water quality detection operation is completed, the driving servo (6) drives the cable (9) to contract and reset.

[0015] Further, the cable (9) supplies power to the nozzle fixer (16), the high-pressure nozzle (17) and the water pump (24), making the water quality monitoring work process more automated and convenient.

[0016] A multifunctional water quality detection method based on a water-air amphibious vehicle of the present invention includes the following steps:

[0017] Step 1, remotely control the water-air amphibious vehicle to land on the water surface of the operation fish pond. The water depth rangefinder (21) and the water pressure sensor (19) detect and upload the underwater information to the main control board (5). After judging that it can enter the water, send an instruction to the driving servo (6), and the winding wheel (10) starts to lower the cable (9);

[0018] Step 2: During the lowering process of the cable (9), the water depth rangefinder (21) determines the relative position between the bottom of the device and the water bottom, and transmits the relative position information to the user terminal through wired communication to achieve real-time obstacle avoidance.

[0019] Step 3: The five groups of water quality detection tubes (18) start to detect the water quality situation and upload the information to the main control board (5) through wired communication.

[0020] Step 4: After completing the water quality detection work, the user terminal sends an "end detection" instruction to the main control board (5) of the present invention. After receiving the instruction, the driving servo (6) controls the cable reel (10) to retract the cable (9) to its original position.

[0021] Step 5: After confirming that the multi-functional water quality detection device has completed the detection work and returned to its position, the main control board (5) sends an instruction to activate the high-pressure cleaning function, and the high-pressure nozzle (17) starts a 3-minute cleaning work.

[0022] Step 6: After the cleaning work is completed, each functional part of the multi-functional water quality detection device checks whether the function is normal. Under normal conditions, the five groups of water quality detection tubes (18) will be inserted into the probe calibration capsule (29) for calibration and maintenance; if any functional part reports an error, the error information will be transmitted to the main control board (5) and then summarized to the user terminal through wireless communication to carry out the next solution measure.

[0023] Advantages of the method of the present invention:

[0024] (1) By controlling the water-air amphibious vehicle to conduct water quality detection, the retractable detection device can flexibly detect the water quality at different water depths, effectively solving the pain points of limited water quality detection areas and inability to conduct multi-dimensional water quality detection in traditional aquaculture. To a certain extent, through automatic control, it brings convenience to fish farmers in fish pond farming.

[0025] (2) The unique bottom-touch detection device measures the water depth in different areas of the fish pond through the water pressure sensor (19) and the underwater rangefinder (21) during operation. The main control board (5) uploads the data to the user terminal through wireless communication to achieve real-time obstacle avoidance and extend the service life of the water quality detection device.

[0026] (3) The present invention is designed with a fully automatic high-pressure cleaning function. In the past, water quality monitors needed to be manually cleaned, and because the probe part is made of delicate materials, if the cleaning is not in place, it is easy to affect the next use and even damage the probe. The present invention integrates water quality detection and detector cleaning functions. The river water is pumped by the water pump (24), filtered, and then the high-pressure nozzle (17) discharges water to remove pollutants such as scale attached to the water quality detector to prevent problems such as deterioration of the detection effect or detection failure of the detector.

[0027] (4) For the daily calibration and maintenance of water quality detection tubes such as dissolved oxygen detection tubes (18), the present invention designs a probe calibration capsule (29). Before the water quality detection operation and after the cleaning work are completed, the present invention can automatically position the probes of water quality detection tubes such as dissolved oxygen detection tubes (18) through the probe tube positioning cap (22), and accurately contract and immerse them into their respective probe calibration capsules (29). The saturated dissolved oxygen water is stored in the chamber, which can maintain and calibrate the dissolved oxygen detection tube to ensure the accuracy of the next underwater detection.

[0028] (5) The cable (9) is a long strip-shaped rigid waterproof wire material, which has better stability than ordinary cylindrical soft wire materials during the lowering process and is not easy to sway back and forth. Description of the Drawings

The carbon tube (3) is fixed through the three-way pipe (11), and the winding wheel (10) is assembled on the same side. One end of the winding wheel (10) is connected to the driving servo (6) through the servo disc (8), and the other end is connected to the carbon tube through the bearing (27). The cable (9) is wound on the bearing (27). The driving servo (6) drives the winding wheel (10) to rotate, so as to realize the winding and unwinding of the cable (9). The driving servo (6) is fixed with the aluminum part (7) and placed in the space supported by the two main control boards (5) through the support carbon tube (4). The main body carbon tube (12) is connected and fixed to the first joint carbon tubes (14) on both sides through the first joint three-way pipe (13). The first joint carbon tube (14) is connected to the nozzle holder (16) through the fixing clamp (15), and the high-pressure nozzle (17) is fixed under the nozzle holder (16). The joint clamp (26) fixes the second joint carbon tube (23) and the disc (30) together. The surface of the above disc (30) is drilled to fix the probe calibration capsule (29). The upper surface of the base disc (20) can be assembled with up to five water quality detection tubes (18) required for water quality detection operations. The underwater rangefinder (21) and the water pressure sensor (19) are assembled on the lower surface of the base disc (20). The upper structure and the lower structure of the present invention are associated through the rigid cable (9). The cable (9) not only plays a role in signal transmission, but also cooperates with the winding wheel (10) and the driving servo (6) in the upper structure to pull up and lower the lower structure. The upper surface of the base disc (20) has a raised columnar body, and a long strip channel is drilled through the center of the columnar body for fixing the cable (9) and providing a channel for the cable (9) to pass through, so as to supply power to the underwater rangefinder (21) and the water pressure sensor (19).

[0038] by Figure 2As shown in the figure, the probe of the detection tube such as the dissolved oxygen detection tube of the present invention is accurately retracted and immersed into its respective probe calibration capsule (29) after being positioned by the probe tube positioning cap (22). The calibration capsule stores saturated dissolved oxygen water, which can maintain and calibrate the dissolved oxygen detection tube to ensure the accuracy of the next underwater detection. During the high-pressure spray cleaning process, the cable (9) can drive the base disc (20) and the equipment thereon to move up and down for thorough cleaning. There are multiple through holes on the surface of the base disc (20), and the water flows out through the through holes without accumulating on the base disc (20).

[0039] As shown Figure 3 As shown in the figure, for the winch part of the multi-functional water quality detection device based on the water-air amphibious vehicle, one end of the winch (10) is connected to the driving servo (6) through the servo disc (8), and the other end is joined to the carbon tube through the bearing (27). The cable (9) is wound and unwound on the bearing (27). The driving servo (6) drives the winch (10) to rotate, thereby realizing the retraction and release of the cable (9).

The multi-functional water quality detection device is installed on the front side of the control cabin board (31) and is fixedly joined to the carbon tube bracket of the water-air amphibious vehicle through the three-way pipe (11) and the first joint three-way pipe (13).

[0041] The present invention uses the driving servo (6) to flexibly retract and release the cable (9) to realize the automatic collection of water quality information, saving labor costs and effectively improving the sampling speed. In addition, the present invention conducts wired communication with the underwater detection device through the main control board (5), and the underwater rangefinder (21) detects the depth from the water bottom to prevent the water quality detection device from being damaged by collision, thereby extending the service life of the present invention. At the same time, the water quality detection equipment is stopped at the required water level height for water quality detection; after each water quality detection work is completed, the driving servo (6) controls the cable (9) to return to its original position. By sending a cleaning instruction from the ground end, the water pump (24) automatically pumps water, and the high-pressure nozzle (17) automatically cleans the water quality detector whose surface is contaminated during the detection process to avoid affecting the accuracy of its detection. Before the water quality detection operation starts and after the cleaning work ends, the present invention can accurately retract and immerse the probes of the water quality detection tubes (18) such as the dissolved oxygen detection tube into their respective probe calibration capsules (29) after positioning through the probe tube positioning cap (22). The calibration capsule stores saturated dissolved oxygen water, which can maintain and calibrate the dissolved oxygen detection tube to ensure the accuracy of the next underwater detection. Thus, it can be seen that the present invention can effectively improve the water quality environment detection efficiency in fields such as fishery aquaculture and bring certain social and economic benefits.

[0042] This invention is an extended part of an amphibious vehicle that can be applied to different water environment detection fields such as fishery farming. Its functions include being able to flexibly detect water quality conditions at different depths, achieving real-time obstacle avoidance through a water pressure sensor (19) and an underwater rangefinder (22), automatically cleaning the water quality detector, and performing general calibration and maintenance on the detection tubes that require calibration and maintenance. This invention can effectively improve the water quality environment detection efficiency in fields such as fishery farming and bring certain social and economic benefits.
