Description

Technical Field

[0001] The present application relates to the technical field of rowing, and in particular to a seawater discharge monitoring method, system, drainage structure and coastal rowing. Background Art

[0002] Coastal rowing is a type of rowing competition that is mainly held in seaside areas. Rowing competitions involve multiple groups of athletes starting from a starting point and rowing on the sea. Whoever reaches the finish line first wins. Due to the presence of waves in the sea, a drainage structure is required on the rowing boat in order to increase the speed of the competition.

[0003] The current drainage measure is to open the stern of the rowing boat. When the athletes row on the sea, seawater enters the rowing boat. When the rowing boat is driven by the seawater and tilts backward, the seawater will automatically be discharged from the open stern.

[0004] During normal driving, the racing boat is in pitch, forward tilt and parallel states. In the forward tilt and parallel states, the open stern allows seawater to enter the hull from the stern. When the racing boat is in the pitch state, although the seawater can be automatically discharged from the open stern, when the wind and waves are strong, more seawater will flow into the hull. The existing drainage method cannot discharge the seawater, which will reduce the overall driving speed. Summary of the invention

[0005] In order to facilitate the rapid travel of a racing boat under different conditions and improve the overall travel speed, the present application provides a seawater discharge monitoring method, system, drainage structure and coastal racing boat.

[0006] In a first aspect, the present application provides a method for monitoring seawater discharge, which adopts the following technical solution: A method for monitoring seawater discharge, Applied to a coastal rowing boat, the coastal rowing boat comprises a posture detection device and a seawater detection device, the posture detection device is arranged on the deck of the rowing boat hull, the seawater detection device is arranged inside the rowing boat hull, the coastal rowing boat comprises a drainage airbag, the drainage airbag is arranged at the rear of the hull, and the drainage airbag comprises an inflated state and a drainage state, the initial state of the drainage airbag is an inflated state, and the method comprises the following steps: Acquire hull data in real time based on the attitude detection device, and acquire the hull attitude according to the hull data; Determining whether the hull posture is in a rearward state; If it is determined that the hull posture is in a backward state, a seawater monitoring signal is generated, and based on the seawater monitoring signal, the seawater detection device is controlled to perform seawater monitoring on the hull of the racing boat to obtain monitoring data; Determining whether the monitoring data is valid data, wherein the valid data indicates that accumulated water to be drained is detected in the hull of the racing boat; If the monitoring data is determined to be valid data, a drainage start signal is generated, and the drainage airbag is controlled to enter a drainage state from an inflated state according to the drainage start signal, so as to drain the accumulated water.

[0007] By adopting the above technical scheme, through judging the posture of the hull, when the posture of the hull is in a backward state, the seawater detection device is controlled based on the seawater monitoring signal to monitor the seawater of the racing boat hull to obtain monitoring data, and then whether there is water to be drained in the racing boat hull is detected. When there is water to be drained in the racing boat hull, the monitoring data is determined to be valid data, and then the drainage airbag is controlled from the inflated state to the drainage state based on the drainage start signal, so as to discharge the water to be drained, which can facilitate the racing boat to travel quickly in different states and improve the overall driving speed.

[0008] In one embodiment, the coastal racing boat further comprises a blowing device, and the blowing device is arranged directly opposite to the stern of the racing boat. After determining that the monitoring data is valid data and generating a drainage start signal, the following steps are further included: The blowing device is activated according to the drainage start signal, so as to control the blowing device to blow air to the stern of the racing boat according to a preset scheme based on the drainage start signal.

[0009] By adopting the above technical scheme, when the racing boat is drained, the drainage airbag is controlled to enter the drainage state according to the drainage start signal, and the blowing device is controlled to start the blowing operation. When the racing boat is in the backward state, the accumulated water to be drained in the hull of the racing boat is blown toward the tail of the racing boat through the blowing device, so that the accumulated water to be tested can flow outward along the slope unfolded at the tail, thereby increasing the speed of the accumulated water to be tested flowing out of the racing boat hull, improving the efficiency of seawater discharge, and thus facilitating the racing boat to travel quickly in different states and improving the overall travel speed.

[0010] In one embodiment, after controlling the drainage airbag from the inflation state to the drainage state according to the drainage start signal, the following steps are also included: Acquiring the hull posture within a specified time based on the drainage start signal, and determining whether the hull posture is in a rearward state; If it is determined that the hull posture is in a rearward state, the drainage airbag is controlled to perform a venting operation according to the drainage start signal; If it is determined that the hull posture is not in the rearward state, a closing airbag signal is generated, and based on the closing airbag signal, the drainage airbag is controlled to perform an inflation operation to enter the inflation state.

[0011] By adopting the above technical solution, when the racing boat is in the rearward state, the hull posture needs to continue to be monitored. When the hull posture changes from the rearward state to other states, the drainage airbag needs to be controlled to change from the drainage state to the inflation state, thereby reducing the entry of seawater from the rear end of the racing boat into the hull of the racing boat when the racing boat is traveling in other states, reducing the deposition of water to be measured on the hull of the racing boat, and thereby increasing the speed of the racing boat.

[0012] In one embodiment, obtaining the hull posture according to the hull data comprises the following steps: Acquire the hull tilt angle and the corresponding tilt direction according to the hull data; Comparing the hull inclination angle with a first preset angle, and determining whether the hull inclination angle is greater than the first preset angle; If the hull inclination angle is greater than the first preset angle, determining whether the inclination direction is tilted backward; If the tilt direction is tilted backward, it is determined that the hull posture is in a backward tilt state.

[0013] By adopting the above technical scheme, based on the comparison between the hull inclination angle and the first preset angle, it is possible to determine whether the racing boat is tilted, and then determine which side the racing boat is tilted to by the inclination direction, so as to accurately determine whether the racing boat is in a backward state, and then quickly decide whether to activate the drainage function of the drainage airbag based on whether there is water in the hull. This can reduce the operation of athletes, and can drain water according to the current driving state of the racing boat, thereby improving the efficiency of seawater discharge.

[0014] In one embodiment, before comparing the hull inclination angle with the first preset angle, the following steps are also included: Acquire sea surface data based on image recognition technology, acquire a predicted hull state based on the sea surface data, and determine whether the predicted hull state is a rearward state; If it is determined that the predicted hull state is a rearward state, comparing the hull inclination angle with a second preset angle; If the hull inclination angle is greater than the second preset angle, it is determined that the hull posture is in a backward state.

[0015] By adopting the above technical solution, the predicted hull state is obtained based on the sea surface data. Before the hull reaches the first preset angle of inclination, the predicted hull state is obtained in advance, so that the drainage operation of the drainage airbag can be quickly started, and the drainage is started when the hull just tilts, which can improve the overall drainage efficiency.

[0016] In a second aspect, the present application provides a seawater discharge monitoring system, which adopts the following technical solution: A seawater discharge monitoring system is applied to a coastal rowing boat, the coastal rowing boat comprises a posture detection device and a seawater detection device, the posture detection device is arranged on the deck of the rowing boat hull, the seawater detection device is arranged inside the rowing boat hull, the coastal rowing boat comprises a drainage airbag, the drainage airbag is arranged at the tail of the hull, and the drainage airbag comprises an inflated state and a drainage state, the initial state of the drainage airbag is an inflated state, the system comprises a posture acquisition module, a data judgment module and a data processing module, the data judgment module is connected to the posture acquisition module through a network, and the data judgment module is connected to the data processing module through a network; The attitude acquisition module acquires hull data based on the attitude detection device, and acquires the hull attitude according to the hull data; The data judgment module is used to judge whether the hull posture is in a backward state; If it is determined that the hull posture is in a backward state, the data processing module is used to generate a seawater monitoring signal, and based on the seawater monitoring signal, control the seawater detection device to monitor the seawater inside the ship to obtain monitoring data; The data judgment module is also used to judge whether the monitoring data is valid data, and the valid data indicates that the accumulated water to be drained is detected in the hull of the racing boat; If the monitoring data is determined to be valid data, the data processing module is used to generate a drainage start signal, and control the drainage airbag from the inflation state to the drainage state according to the drainage start signal, so as to drain the accumulated water.

[0017] In a third aspect, the present application provides a drainage structure, which adopts the following technical solution: A drainage structure, comprising: A drainage airbag, which is arranged at the tail of the racing boat and has a flexible layer on its surface; The blowing device is arranged above the hull, and the exhaust port of the blowing device is arranged directly opposite to the drainage airbag.

[0018] By adopting the above technical scheme, the racing boat is drained based on the drainage airbag and the blowing device, and the racing boat is drained by the seawater discharge monitoring method described in the first aspect. The drainage airbag expands the flexible layer when inflated, so that the tail of the racing boat can block part of the seawater from entering the racing boat hull. When the racing boat needs to be drained, the exhaust airbag enters the drainage state according to the drainage start signal, and turns on the blowing device at the same time, so that the seawater can be quickly discharged from the racing boat hull, thereby improving the overall hull drainage efficiency.

[0019] In one embodiment, the drainage airbags are provided in plurality, and the plurality of drainage airbags are arranged in descending order toward the stern of the racing boat; Wherein, when the drainage airbag is inflated, the tail of the racing boat is higher than the hull of the racing boat. When the drainage airbag is in the drainage state, the tail of the racing boat is unfolded downward along the hull, and the hull of the racing boat is higher than the tail of the racing boat.

[0020] By adopting the above technical solution, multiple drainage airbags are provided, which are reduced in size along the hull toward the stern when inflated. When the racing boat is operating normally, they can block part of the water and prevent it from entering the hull. When drainage is required, it is necessary to facilitate the discharge of seawater, thereby improving the efficiency of seawater discharge.

[0021] In one embodiment, the blowing device is provided with a baffle at the air outlet, and the baffle moves up and down in a direction perpendicular to the hull of the racing boat; Among them, when the hull posture is in a backward state, the baffle moves upward along the vertical racing boat hull until the exhaust port is facing the drainage airbag. When the racing boat enters a forward state or a parallel state, the baffle moves downward along the vertical racing boat hull until the baffle is engaged with the racing boat hull.

[0022] By adopting the above technical solution, when the hull is normally traveling, the baffle will block seawater from entering the inside of the blowing device and causing damage to the blowing device. When the racing boat needs to drain water, the baffle will open in a direction perpendicular to the racing boat hull to enable blowing operation to be performed toward the stern of the racing boat, so that the accumulated water in the hull can quickly flow out of the hull, thereby improving the efficiency of seawater discharge.

[0023] In a fourth aspect, the present application provides a coastal rowing boat, which adopts the following technical solution: A coastal racing boat comprises the drainage structure described in the third aspect above.

When there is water to be drained in the hull of the racing boat, the monitoring data is determined to be valid data, and then the drainage airbag is controlled from the inflated state to the drainage state based on the drainage start signal, so as to drain the water to be drained, which can facilitate the racing boat to travel quickly in different states and improve the overall travel speed; 2. When the racing boat is draining water, the drainage airbag is controlled to enter the drainage state according to the drainage start signal, and the blowing device is controlled to start the blowing operation. When the racing boat is in the backward state, the accumulated water to be drained in the hull of the racing boat is blown toward the tail of the racing boat through the blowing device, so that the accumulated water to be tested can flow outward along the slope unfolded at the tail, thereby increasing the speed of the accumulated water to be tested flowing out of the racing boat hull, improving the efficiency of seawater discharge, and thus facilitating the racing boat to travel quickly in different states and improving the overall travel speed.

[0027] To more clearly understand the purpose, technical solutions and advantages of the present application, the present application is described and illustrated below in conjunction with the accompanying drawings and embodiments. However, it should be understood by those of ordinary skill in the art that the present application can be implemented without these details. In some cases, in order to avoid unnecessary descriptions that make various aspects of the present application obscure, well-known methods, processes, systems, components and / or circuits that have been described at a higher level will not be described in detail. For those of ordinary skill in the art, it is obvious that various changes can be made to the embodiments disclosed in the present application, and without departing from the principles and scope of the present application, the general principles defined in the present application can be applied to other embodiments and application scenarios. Therefore, the present application is not limited to the embodiments shown, but conforms to the broadest scope consistent with the scope claimed for protection of the present application.

[0028] Reference Figure 1 and Figure 2The embodiment of the present application discloses a seawater discharge monitoring method, which is applied to a coastal racing boat. The coastal racing boat includes a drainage airbag 10, a posture detection device and a seawater detection device. The posture detection device is arranged on the deck of the racing boat hull 41, the seawater detection device is arranged inside the racing boat hull 41, the drainage airbag 10 is arranged at the tail of the hull, and the drainage airbag 10 includes an inflated state and a drainage state. Figure 1 and Figure 2 The symbol F is the direction of seawater flow, such as Figure 1 As shown, the drainage airbag 10 is inflated, and the tail of the racing boat is higher than the hull, which can prevent seawater from entering the hull from the tail. Figure 2 As shown, the drainage airbag 10 is in a drainage state. The drainage airbag 10 is in the drainage state, which specifically means that the drainage airbag 10 discharges the gas inside it, so that the entire racing boat slopes downward along the hull toward the stern, and the hull is higher than the stern, which is convenient for the racing boat to discharge the accumulated water inside the hull out of the hull along the stern.

[0029] Combination Figure 3 , a seawater discharge monitoring method, comprising the following steps: S100, acquiring hull data in real time based on a posture detection device, and acquiring the hull posture according to the hull data.

[0030] The hull data represents the data of the hull's travel process, including the hull's tilt angle, tilt direction, etc. The hull's posture includes the backward state, forward state, and parallel state, etc. The posture detection device is specifically used to monitor the hull's travel data. A posture sensor can be used, which is specifically installed on a horizontal platform on the deck of the hull, and can accurately measure the hull's tilt angle during travel and the tilt direction corresponding to the tilt angle.

[0031] It should be noted here that when the athlete is running, the processor obtains the hull data in real time based on the attitude detection device, and analyzes the real-time obtained hull data to obtain the hull attitude, and then can obtain the accurate hull attitude, wherein obtaining the hull attitude based on the hull data includes the following steps: S110, obtaining a hull tilt angle and a corresponding tilt direction according to the hull data.

[0032] S120, comparing the hull inclination angle with a first preset angle, and determining whether the hull inclination angle is greater than the first preset angle.

[0033] S130: If the hull tilt angle is greater than a first preset angle, determine whether the tilt direction is tilted backward.

[0034] S140: If the tilt direction is tilted backward, it is determined that the hull posture is in a backward tilt state.

[0035] Among them, the first preset angle represents the angle set in advance, which determines whether the hull is the lowest standard angle of forward or backward tilt, and the angle can be set according to the running state of the hull. When the hull tilt angle is not greater than the first preset angle, there is no need to perform corresponding operations, and it is only necessary to continue to obtain hull data based on the attitude detection state and process the hull data. If it is determined that the tilt direction is not tilted backward, it indicates that the hull can travel in a parallel state or in a forward tilt state. At this time, there is no need to start the drainage operation for the racing boat.

[0036] It should be noted here that the first preset angle is stored in the memory. When the processor needs to process the hull data, it can send an angle acquisition signal to the memory. After receiving the angle acquisition signal, the memory will send the first preset angle to the processor, so that the processor can obtain the hull inclination angle and the corresponding inclination direction based on the hull data, and compare the hull inclination angle with the first preset angle to obtain the current hull posture.

[0037] S200, determining whether the ship's hull posture is in a rearward state.

[0038] S300: If it is determined that the hull posture is in a backward state, a seawater monitoring signal is generated, and based on the seawater monitoring signal, a seawater detection device is controlled to perform seawater monitoring on the hull of the racing boat to obtain monitoring data.

[0039] The seawater monitoring signal represents the signal generated by the processor, which is specifically used to control the seawater monitoring device to detect water accumulation on the hull. The monitoring data represents the monitoring results obtained by the seawater detection device.

[0040] S400, determining whether the monitoring data is valid data.

[0041] The monitoring data includes valid data and invalid data. The valid data indicates that accumulated water to be discharged is detected in the hull of the racing boat, and the invalid data indicates that accumulated water to be discharged is not detected in the hull of the racing boat.

[0042] It should be noted here that valid data indicates that accumulated water to be drained has been detected, and the amount of accumulated water to be drained has reached the minimum standard for drainage. Therefore, the processor obtains the monitoring data obtained by the seawater detection device, processes the detection data, and then determines whether the current amount of accumulated water meets the requirements for drainage operation. If it meets the requirements for drainage operation, the current monitoring data is determined to be valid data. If it does not meet the requirements for drainage operation, the current monitoring data is determined to be invalid data.

[0043] S500: If the monitoring data is determined to be valid data, a drainage start signal is generated, and the drainage airbag is controlled to enter a drainage state from an inflated state according to the drainage start signal to facilitate the discharge of seawater.

[0044] Among them, the drainage start signal represents a signal generated by the processor based on the monitoring data being valid data, specifically to control the drainage airbag 10 from the inflated state to the drainage state, so as to discharge the accumulated water in the hull.

[0045] Reference Figure 1 and Figure 2 In one embodiment, the coastal racing boat further comprises a blower 20, which is arranged facing the stern 42 of the racing boat. After determining that the monitoring data is valid data and generating a drainage start signal, the following steps are also included: S600, starting the blowing device according to the drainage start signal, so as to control the blowing device to blow air to the stern of the racing boat according to a preset scheme based on the drainage start signal.

[0046] The blower device 20 is mainly installed on the hull of the racing boat, and the air outlet of the blower device 20 faces the drainage airbag 10. When the processor generates a drainage start signal, the drainage airbag 10 enters the drainage state from the inflated state, and the blower device 20 starts the blowing function and blows air toward the stern 42 of the racing boat, thereby blowing the accumulated water to be drained from the hull to the stern, and draining it outward along the drainage airbag 10 at the stern.

[0047] It should be noted here that the preset scheme refers to turning on the blowing intensity. When it is detected that there is water to be drained in the racing boat hull 41, it is necessary to set different wind strengths for blowing according to the amount of water to be drained. The processor needs to detect the amount of water to be detected. If the amount of water exceeds the preset amount, the first-level blowing mode is turned on. If the amount does not exceed the preset amount, the second-level blowing mode is turned on. The first-level blowing mode is stronger than the second-level blowing mode.

[0048] Reference Figure 1 and Figure 4 In one embodiment, after the drainage airbag 10 is controlled to enter the drainage state from the inflated state according to the drainage start signal, the following steps are also included: S510, obtaining the hull posture within a specified time based on the drainage start signal, and determining whether the hull posture is in a rearward state.

[0049] S520, if the hull posture is in the rearward state, the drainage airbag is controlled to continue to be in the drainage state according to the drainage start signal.

[0050] S530: If the hull posture is not in the backward state, a closing airbag signal is generated, and the drainage airbag is controlled to enter the inflation state based on the closing airbag signal.

[0051] Among them, the designated time represents the time interval for obtaining the hull posture after the drainage airbag 10 is in the drainage state. When the drainage airbag 10 is in the drainage state, there is no need to obtain the hull posture in real time, and the drainage state can be obtained according to the designated time, thereby reducing the number of data processing times by the processor.

[0052] It should be noted here that the designated time is set according to the running process of the racing boat. Specifically, the interval duration when the racing boat is in the backward state is determined by the current sea conditions. The designated time does not exceed the interval duration, and the designated time must be greater than the interval for obtaining real-time hull data.

[0053] The airbag closing signal represents a signal generated by the processor when it determines that the hull posture is not in the backward state, specifically controlling the drainage airbag 10 to enter the inflation state from the drainage state, that is, controlling the drainage airbag 10 to return to the initial position.

[0054] It should be noted here that the airbag closing signal also controls the blowing device 20 to close the blowing operation.

[0055] In one embodiment, before comparing the hull inclination angle with the preset angle, the method further includes the following steps: S111, acquiring sea surface data based on image recognition technology, acquiring a predicted hull state based on the sea surface data, and determining whether the predicted hull state is a rearward state.

[0056] S112: If the predicted hull state is determined to be a rearward state, the hull inclination angle is compared with a second preset angle.

[0057] S113: If the hull inclination angle is greater than a second preset angle, it is determined that the hull posture is in a backward state.

[0058] The sea surface data represents the sea surface conditions of the sea area where the current rowing boat is traveling, and the predicted hull state represents the prediction result obtained based on the sea surface data. Different from the first preset angle, the second preset angle represents the lowest angle for predicting the hull state to be in the backward state, and the second preset angle is smaller than the first preset angle. The size here is mainly to compare the angle values, and the first preset angle and the second preset angle are both angles in the same direction for comparison.

[0059] It should be noted that the image recognition technology specifically recognizes the image to obtain the specific situation corresponding to the image. The image recognition technology here is a prior art and will not be elaborated here. The sea surface data is obtained by recognizing the sea surface photos taken by the camera set on the racing boat based on the image recognition technology. The predicted hull state can be obtained by training the state generation model based on the historical hull sea surface data and the corresponding hull state during operation, and the sea surface data is input into the state generation model to obtain the corresponding predicted hull state.

[0060] The state generation model here can be a conventional target detection network. As long as the sea surface data is input into the state generation model, the corresponding predicted hull state can be obtained. The target detection network can be RFCN / SSD / RCNN / FastRCNN / FasterRCNN / SPPNet / DPM / OverFeat / YOLO, etc.

[0061] Reference Figure 1 The embodiment of the present application also discloses a seawater discharge monitoring system, which is applied to a coastal racing boat. The coastal racing boat includes a posture detection device and a seawater detection device. The posture detection device is arranged on the deck of the racing boat hull 41, and the seawater detection device is arranged inside the racing boat hull 41. The coastal racing boat includes a drainage airbag 10, and the drainage airbag 10 is arranged at the tail of the hull. The drainage airbag 10 includes an inflated state and a drainage state. The initial state of the drainage airbag 10 is an inflated state.

[0062] like Figure 5 As shown, the seawater discharge monitoring system includes a posture acquisition module 50, a data judgment module 60 and a data processing module 70. The data judgment module 60 is connected to the posture acquisition module 50 via a network, and the data judgment module 60 is connected to the data processing module 70 via a network.

[0063] The posture acquisition module 50 acquires the hull data based on the posture detection device, and acquires the hull posture according to the hull data.

[0064] The data judgment module 60 is used to judge whether the hull posture is in a backward state.

[0065] If it is determined that the hull posture is in a backward state, the data processing module 70 is used to generate a seawater monitoring signal, and control the seawater detection device to monitor the seawater inside the ship based on the seawater monitoring signal to obtain monitoring data.

[0066] The data judgment module 60 is also used to judge whether the monitoring data is valid data, and the valid data indicates that the accumulated water to be drained is detected in the hull of the racing boat.

[0067] If the monitoring data is determined to be valid data, the data processing module 70 is used to generate a drainage start signal, and control the drainage airbag 10 from the inflation state to the drainage state according to the drainage start signal, so as to drain the accumulated water.

[0068] Among them, the hull data, hull posture, seawater monitoring signal, monitoring data and drainage start signal are the same or similar to the seawater discharge monitoring method described above, so no detailed description will be given here.

[0069] Other functions performed in the above-mentioned posture acquisition module 50, data judgment module 60 and data processing module 70 and the technical details of each function are the same or similar to the corresponding features in the seawater discharge monitoring method described above, so they are not repeated here.

[0070] The embodiment of the present application also discloses a drainage structure.

[0071] Reference Figure 1 and Figure 2 The drainage structure includes a drainage airbag 10, which is arranged at the tail of the racing boat, and a flexible layer 30 is arranged on the surface of the drainage airbag 10.

[0072] The blowing device 20 is arranged above the hull, and the air outlet of the blowing device 20 faces the drainage airbag 10 .

[0073] Specifically, in the initial state, the drainage airbag 10 is in an inflated state, the flexible layer 30 is on the surface of the drainage airbag 10, the tail of the racing boat is tilted downward from the hull to the tail, and the highest point of the tail is higher than the hull, thereby preventing the water on the sea surface from entering the hull from the tail. The air blowing device 20 is installed on the hull, and the air blowing device 20 includes a fan, an air outlet and a drive motor. The air outlet faces the stern. When the processor generates a drainage start signal, it controls the drive motor to start the fan according to the drainage start signal.

[0074] In one embodiment, a plurality of drainage airbags 10 are provided, and the plurality of drainage airbags 10 are arranged in order from large to small toward the stern 42 of the racing boat.

[0075] Wherein, when the drainage airbag 10 is inflated, the tail of the racing boat is higher than the racing boat hull 41; when the drainage airbag 10 is in the drainage state, the tail of the racing boat is unfolded downward along the hull, and the racing boat hull 41 is higher than the tail of the racing boat.

[0076] In one embodiment, the blowing device 20 is provided with a baffle at the air outlet position, and the baffle moves up and down in a direction perpendicular to the hull 41 of the racing boat.

[0077] Among them, when the hull posture is in a backward state, the baffle moves upward along the vertical racing boat hull 41 until the exhaust port is facing the drainage airbag 10. When the racing boat enters a forward state or a parallel state, the baffle moves downward along the vertical racing boat hull 41 until the baffle is engaged with the racing boat hull 41.

[0078] The embodiment of the present application also discloses a coastal racing boat, which includes the drainage structure described above.

[0079] The implementation principle is: When the athlete is running, the processor obtains the hull data in real time based on the attitude detection device, and analyzes the real-time acquired hull data to obtain the hull attitude. It is judged whether the hull attitude is in a backward state. If it is judged that the hull attitude is in a backward state, a seawater monitoring signal is generated, and the seawater detection device is controlled based on the seawater monitoring signal to monitor the seawater of the hull of the rowing boat to obtain monitoring data. It is judged whether the monitoring data is valid data. If it is judged that the monitoring data is valid data, a drainage start signal is generated, and the drainage airbag 10 is controlled to enter the drainage state from the inflated state according to the drainage start signal to discharge the seawater.

[0080] It should be understood that although the steps in the flowchart of the accompanying drawings are shown in sequence according to the instructions of the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise clearly stated in this document, the execution of these steps is not strictly limited in order and can be performed in other orders.

[0081] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
