Description

Technical Field

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

[0002] A coastal rowing boat is mainly a rowing boat for racing in coastal areas. The rowing boat race includes multiple groups of athletes starting from the starting point and rowing on the seawater. The one who reaches the finish line first wins. Since there are waves in the seawater, in order to improve the racing speed, a drainage structure is required on the rowing boat.

[0003] Currently, the drainage measure is to keep the tail of the rowing boat open. When the athlete rows on the sea, seawater enters the rowing boat. When the rowing boat tilts backward driven by the seawater during movement, the seawater will automatically drain out from the open tail.

[0004] During the normal driving process of the rowing boat, including the pitching state, the forward tilting state, and the parallel state, in the forward tilting state and the parallel state, the open tail will cause seawater to enter the hull from the tail. When the rowing boat is in the pitching state, although the seawater can automatically drain out from the open tail, when the wind and waves are relatively large, a large amount of seawater surges into the hull, and the existing drainage method cannot achieve the discharge of seawater, thus reducing the overall driving speed. Summary of the Invention

[0005] In order to facilitate the rapid driving of the rowing boat in different states and improve the overall driving speed, the present application provides a seawater discharge monitoring method, system, drainage structure, and coastal rowing boat.

[0006] In the first aspect, the present application provides a seawater discharge monitoring method, adopting the following technical solution:

[0007] A seawater discharge monitoring method,

[0008] which is applied to a coastal rowing boat. The coastal rowing boat includes an attitude detection device and a seawater detection device. The attitude detection device is arranged on the deck of the rowing boat hull, and the seawater detection device is arranged inside the rowing boat hull. The coastal rowing boat includes a drainage airbag, which is arranged at the tail of the hull. The drainage airbag includes an inflated state and a drainage state. The initial state of the drainage airbag is the inflated state. The method includes the following steps:

[0009] Based on the attitude detection device, the hull data is obtained in real time, and the hull attitude is obtained according to the hull data;

[0010] Judge whether the hull attitude is a backward tilting state;

[0011] If it is determined that the hull attitude is in a backward tilt state, a seawater monitoring signal is generated, and based on the seawater monitoring signal, the seawater detection device is controlled to monitor the hull of the rowing boat for seawater to obtain monitoring data;

[0012] Judge whether the monitoring data is valid data, and the valid data indicates that accumulated water to be drained is detected inside the rowing boat hull;

[0013] If it is determined that the monitoring data is valid data, a drainage start signal is generated, and based on the drainage start signal, the drainage airbag is controlled to enter the drainage state from the inflated state to facilitate the drainage of the accumulated water to be drained.

[0014] By adopting the above technical solution, through the judgment of the hull attitude, when the hull attitude is in a backward tilt state, based on the seawater monitoring signal, the seawater detection device is controlled to monitor the hull of the rowing boat for seawater to obtain monitoring data, and then it is detected whether there is accumulated water to be drained in the rowing boat hull. When there is accumulated water to be drained in the rowing boat hull, it is determined that the monitoring data is valid data. Furthermore, based on the drainage start signal, the drainage airbag is controlled to enter the drainage state from the inflated state to facilitate the drainage of the accumulated water to be drained, which can facilitate the rowing boat to travel quickly in different states and improve the overall traveling speed.

[0015] In one of the embodiments, the coastal rowing boat further includes a blower device, and the blower device is arranged facing the stern of the rowing boat. After it is determined that the monitoring data is valid data and a drainage start signal is generated, the following steps are further included:

[0016] Based on the drainage start signal, the blower device is started so as to control the blower device to blow air at the stern of the rowing boat according to a preset scheme.

[0017] By adopting the above technical solution, when draining the rowing boat, while controlling the drainage airbag to enter the drainage state according to the drainage start signal, the blower device is controlled to start blowing air. When the rowing boat is in a backward tilt state, the accumulated water to be drained inside the rowing boat is blown towards the stern of the rowing boat by the blower device. Furthermore, the accumulated water to be detected can flow outwards along the slope unfolded at the stern, improving the speed of the accumulated water to be detected flowing out of the rowing boat hull and the seawater drainage efficiency. Furthermore, it is convenient for the rowing boat to travel quickly in different states and improves the overall traveling speed.

[0018] In one of the embodiments, after controlling the drainage airbag to enter the drainage state from the inflated state based on the drainage start signal, the following steps are further included:

[0019] Based on the drainage start signal, the hull attitude is obtained within a specified time, and it is judged whether the hull attitude is in a backward tilt state;

[0020] If it is determined that the hull attitude is in a backward tilt state, control the drainage airbag to perform an exhaust operation according to the drainage opening signal;

[0021] If it is determined that the hull attitude is not in a backward tilt state, generate a signal to close the airbag, and control the drainage airbag to perform an inflation operation based on the signal to close the airbag to enter the inflation state.

[0022] By adopting the above technical solution, when the rowing boat is in a backward tilt state, it is necessary to continue monitoring the hull attitude. When the hull attitude changes from the backward tilt state to other states, it is necessary to control the drainage airbag to change from the drainage state to the inflation state, so as to reduce the entry of seawater from the tail of the rowing boat into the hull of the rowing boat when the rowing boat is in other states, reduce the deposition of accumulated water to be measured in the hull of the rowing boat, and thus improve the driving speed of the rowing boat.

[0023] In one of the embodiments, obtaining the hull attitude based on the hull data includes the following steps:

[0024] Obtain the hull tilt angle and the corresponding tilt direction based on the hull data;

[0025] Compare the hull tilt angle with a first preset angle, and determine whether the hull tilt angle is greater than the first preset angle;

[0026] If the hull tilt angle is greater than the first preset angle, determine whether the tilt direction is backward;

[0027] If the tilt direction is backward, determine that the hull attitude is in a backward tilt state.

[0028] By adopting the above technical solution, based on the comparison between the hull tilt angle and the first preset angle, it can be further obtained whether the rowing boat is tilted, and then by the tilt direction, it can be determined which side the rowing boat is tilted to, so as to accurately determine that the rowing boat is in a backward tilt state, and then quickly determine whether to open the drainage function of the drainage airbag according to whether there is water in the hull, which can reduce the operation of the athlete and can drain water according to the current driving state of the rowing boat, improving the drainage efficiency of seawater.

[0029] In one of the embodiments, before comparing the hull tilt angle with the first preset angle, the following steps are further included:

[0030] Obtain sea surface data based on image recognition technology, obtain a predicted hull state based on the sea surface data, and determine whether the predicted hull state is in a backward tilt state;

[0031] If it is determined that the predicted hull state is in a backward tilt state, compare the hull tilt angle with a second preset angle;

[0032] If the hull tilt angle is greater than the second preset angle, it is determined that the hull attitude is in a backward tilt state.

[0033] 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 tilt, the predicted hull state is obtained in advance, and then the drainage operation of the drainage airbag can be quickly started. Therefore, when the hull just starts to tilt, the drainage can be started, which can improve the overall drainage efficiency.

[0034] In a second aspect, the present application provides a seawater discharge monitoring system, adopting the following technical solution:

[0035] A seawater discharge monitoring system is applied to a coastal racing boat. The coastal racing boat includes an attitude detection device and a seawater detection device. The attitude detection device is arranged on the deck of the racing boat hull, and the seawater detection device is arranged inside the racing boat hull. The coastal racing boat includes a drainage airbag, which is arranged at the tail of the hull, and the drainage airbag includes an inflated state and a drainage state. The initial state of the drainage airbag is the inflated state. The system includes an attitude acquisition module, a data judgment module, and a data processing module. The data judgment module is network-connected to the attitude acquisition module, and the data judgment module is network-connected to the data processing module;

[0036] The attitude acquisition module acquires hull data based on the attitude detection device and obtains the hull attitude according to the hull data;

[0037] The data judgment module is used to judge whether the hull attitude is in a backward tilt state;

[0038] If it is determined that the hull attitude is in a backward tilt state, the data processing module is used to generate a seawater monitoring signal and control the seawater detection device to monitor the seawater inside the boat based on the seawater monitoring signal to obtain monitoring data;

[0039] The data judgment module is also used to judge whether the monitoring data is valid data, and the valid data indicates that accumulated water to be drained is detected inside the racing boat;

[0040] If it is determined that the monitoring data is valid data, the data processing module is used to generate a drainage start signal and control the drainage airbag to enter the drainage state from the inflated state according to the drainage start signal, so as to drain the accumulated water to be drained.

[0041] In a third aspect, the present application provides a drainage structure, adopting the following technical solution:

[0042] A drainage structure includes:

[0043] A drainage airbag, which is arranged at the tail of the racing boat and has a flexible layer on its surface;

[0044] The blowing device is arranged above the hull, and the exhaust port of the blowing device is arranged directly opposite to the drainage airbag.

[0045] 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.

[0046] 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;

[0047] 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.

[0048] 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.

[0049] 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;

[0050] 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.

[0051] 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.

[0052] In a fourth aspect, the present application provides a coastal rowing boat, which adopts the following technical solution:

[0053] A coastal rowing boat includes the drainage structure described in the above third aspect.

[0054] In summary, the present application includes at least one of the following beneficial technical effects:

[0055] 1. By judging the attitude of the hull, when the hull attitude is in a backward-leaning state, based on the seawater monitoring signal, the seawater detection device is controlled to monitor the hull of the rowing boat to obtain monitoring data, and then it is detected whether there is accumulated water to be drained in the hull of the rowing boat. When there is accumulated water to be drained in the hull of the rowing boat, the monitoring data is determined to be valid data, and then based on the drainage opening signal, the drainage airbag is controlled to enter the drainage state from the inflated state, so as to facilitate the discharge of the accumulated water to be drained, which can facilitate the rowing boat to travel quickly in different states and improve the overall traveling speed.

[0056] 2. When draining the rowing boat, while controlling the drainage airbag to enter the drainage state according to the drainage opening signal, the air blowing device is controlled to start the air blowing operation. When the rowing boat is in a backward-leaning state, the accumulated water to be drained in the hull of the rowing boat is blown towards the tail of the rowing boat by the air blowing device, and then the accumulated water to be detected can flow outwards along the slope unfolded at the tail, improving the speed of the accumulated water to be detected flowing out of the hull of the rowing boat, improving the seawater drainage efficiency, and then facilitating the rowing boat to travel quickly in different states and improving the overall traveling speed.

[0063] To better understand the purpose, technical solution, and advantages of the present application, the present application will be described and explained below in conjunction with the accompanying drawings and embodiments. However, those of ordinary skill in the art should understand that the present application can be implemented without these details. In some cases, to avoid unnecessary description making 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 elaborated further. For those of ordinary skill in the art, it is obvious that various changes can be made to the disclosed embodiments of 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 illustrated embodiments, but conforms to the broadest scope consistent with the scope claimed in the present application.

[0064] Referring to Figure 1 and Figure 2 , an embodiment of the present application discloses a seawater discharge monitoring method, which is applied to a coastal rowing boat. The coastal rowing boat includes a drainage airbag 10, an attitude detection device, and a seawater detection device. The attitude detection device is arranged on the deck of the rowing boat hull 41, and the seawater detection device is arranged inside the rowing 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 In which, the identifier F in Figure 1 indicates the flow direction of seawater. As Figure 2 shown, when the drainage airbag 10 is in the inflated state, the tail of the rowing boat is higher than the hull, which can prevent seawater from entering the hull from the tail. As Figure 2 shown, when the drainage airbag 10 is in the drainage state, specifically, the drainage airbag 10 discharges the gas inside it, so that the whole rowing boat slopes downward along the hull towards the stern, and the hull is higher than the tail, facilitating the rowing boat to drain the accumulated water inside the hull along the tail.

[0065] Combined with Figure 3 , the seawater discharge monitoring method includes the following steps:

[0066] S100, based on the attitude detection device, obtain the hull data in real time, and obtain the hull attitude according to the hull data.

[0067] Among them, the hull data represents the data during the hull's travel, specifically including the tilt angle and tilt direction of the hull, etc. The hull attitude includes a rearward tilt state, a forward tilt state, and a parallel state, etc. The attitude detection device is specifically used to monitor the travel data of the hull, and an attitude sensor can be used, which is specifically installed on the horizontal platform of the deck of the hull and can accurately measure the tilt angle of the hull during travel and the tilt direction corresponding to the tilt angle, etc.

[0068] It should be noted here that when the athlete is in the process of driving, the processor obtains the hull data in real time based on the attitude detection device, analyzes the hull data obtained in real time to obtain the hull attitude, and thus can obtain an accurate hull attitude. Among them, obtaining the hull attitude based on the hull data includes the following steps:

[0069] S110, obtain the hull tilt angle and the corresponding tilt direction based on the hull data.

[0070] S120, compare the hull tilt angle with the first preset angle and determine whether the hull tilt angle is greater than the first preset angle.

[0071] S130, if the hull tilt angle is greater than the first preset angle, then determine whether the tilt direction is backward tilt.

[0072] S140, if the tilt direction is backward tilt, then determine that the hull attitude is a backward-leaning state.

[0073] Among them, the first preset angle represents the angle set in advance, which is the minimum standard angle for determining whether the hull is forward-leaning or backward-leaning, and this angle can be set according to the hull running state. When the hull tilt angle is not greater than the first preset angle, no corresponding operation is required, and only the hull data needs to be continuously obtained based on the attitude detection state and the hull data needs to be processed. If it is determined that the tilt direction is not backward tilt, it means that the hull can travel in a parallel state or a forward-leaning state. At this time, there is no need to start the drainage operation for the rowing boat.

[0074] 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 tilt angle and the corresponding tilt direction based on the hull data, and compare the hull tilt angle with the first preset angle to obtain the current hull attitude.

[0075] S200, determine whether the hull attitude is a backward-leaning state.

[0076] S300, if it is determined that the hull attitude is a backward-leaning state, then generate a seawater monitoring signal and control the seawater detection device to monitor the hull of the rowing boat based on the seawater monitoring signal to obtain monitoring data.

[0077] Among them, the seawater monitoring signal represents the signal generated by the processor, which is specifically used to control the seawater monitoring device to detect the accumulated water on the hull. The monitoring data represents the monitoring results obtained by the seawater detection device.

[0078] S400, determine whether the monitoring data is valid data.

[0079] Among them, the monitoring data includes valid data and invalid data. The valid data indicates that accumulated water to be drained is detected inside the hull of the rowing boat, and the invalid data indicates that no accumulated water to be drained is detected inside the hull of the rowing boat.

[0080] It should be noted here that the valid data indicates that accumulated water to be drained is detected, and the amount of the accumulated water to be drained reaches the lowest standard for drainage. Therefore, when the processor obtains the monitoring data acquired by the seawater detection device, by processing the detection data, it further determines whether the current amount of accumulated water meets the drainage operation. If it meets the drainage operation, the current monitoring data is determined to be valid data. If it does not meet the drainage operation, the current monitoring data is determined not to be valid data.

[0081] S500, if it is determined that the monitoring data is valid data, a drainage start signal is generated, and the drainage airbag is controlled to enter the drainage state from the inflated state according to the drainage start signal, so as to drain the seawater.

[0082] Among them, the drainage start signal is a signal generated by the processor based on the valid monitoring data. Specifically, it is to control the drainage airbag 10 to enter the drainage state from the inflated state, so as to drain the accumulated water to be drained from the hull.

[0083] Refer to Figure 1 and Figure 2 , in one of the embodiments, the coastal rowing boat further includes a blower device 20. The blower device 20 is arranged facing the stern 42 of the rowing boat. After it is determined that the monitoring data is valid data and a drainage start signal is generated, the following steps are further included:

[0084] S600, start the blower device according to the drainage start signal, so as to control the blower device to blow air on the stern of the rowing boat according to a preset scheme based on the drainage start signal.

[0085] Among them, the blower device 20 is mainly installed on the hull of the rowing boat, and the air outlet of the blower device 20 faces the drainage airbag 10. When the processor generates the drainage start signal and the drainage airbag 10 enters the drainage state from the inflated state, the blower device 20 starts the blowing function and blows air towards the stern 42 of the rowing boat, thereby blowing the accumulated water to be drained from the hull to the tail and discharging it outward along the drainage airbag 10 at the tail.

[0086] It should be noted here that the preset scheme refers to the blowing intensity. When it is detected that there is accumulated water to be drained in the hull 41 of the rowing boat, different wind force magnitudes need to be set for blowing according to the amount of the accumulated water to be drained. The processor needs to detect the amount of the accumulated water to be measured. If the amount of water exceeds the preset amount of water, the first-level blowing mode is turned on. If the amount does not exceed the preset amount of water, the second-level blowing mode is turned on. The first-level blowing mode is stronger than the second-level blowing mode.

[0087] Refer to Figure 1 andFigure 4 , in one of the embodiments, after controlling the drainage airbag 10 to enter the drainage state from the inflated state according to the drainage opening signal, the following steps are further included:

[0088] S510, obtain the hull attitude within a specified time based on the drainage opening signal, and determine whether the hull attitude is in a reclined state.

[0089] S520, if the hull attitude is in a reclined state, control the drainage airbag to continue to be in the drainage state according to the drainage opening signal.

[0090] S530, if the hull attitude is not in a reclined state, generate a signal to close the airbag, and control the drainage airbag to enter the inflated state based on the signal to close the airbag.

[0091] Wherein, the specified time represents the time interval for obtaining the hull attitude after the drainage airbag 10 is in the drainage state. When the drainage airbag 10 is in the drainage state, it is not necessary to obtain the hull attitude in real time, and the drainage state can be obtained according to the specified time, so as to reduce the number of data processing times by the processor.

[0092] It should be noted here that the specified time is set according to the operation process of the rowing boat. Specifically, the interval duration when the rowing boat is in a reclined state is determined according to the conditions of the current sea area. The specified time does not exceed the interval duration, and the specified time should be greater than the interval for obtaining the hull data in real time.

[0093] The signal to close the airbag represents the signal generated by the processor when it determines that the hull attitude is not in a reclined state. Specifically, it controls the drainage airbag 10 to enter the inflated state from the drainage state, that is, controls the drainage airbag 10 to return to the initial position.

[0094] It should be noted here that the signal to close the airbag also controls the blower device 20 to stop the blowing operation.

[0095] In one of the embodiments, before comparing the hull tilt angle with the preset angle, the following steps are further included:

[0096] S111, obtain the sea surface data based on the image recognition technology, obtain the predicted hull state according to the sea surface data, and determine whether the predicted hull state is in a reclined state.

[0097] S112, if it is determined that the predicted hull state is in a reclined state, compare the hull tilt angle with the second preset angle.

[0098] S113, if the hull tilt angle is greater than the second preset angle, determine that the hull attitude is in a reclined state.

[0099] Among them, the sea surface data characterizes 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 minimum angle for predicting that the hull state is in a backward state, and the second preset angle is smaller than the first preset angle. Here, the size mainly compares the angle values, and both the first preset angle and the second preset angle are compared for angles in the same direction.

[0100] It should be noted here that the image recognition technology specifically recognizes an image to obtain the specific situation corresponding to the image. Here, the image recognition technology is an existing technology, and there will be no further elaboration here. The sea surface data is the data obtained by recognizing the sea surface photos taken by the camera installed on the rowing boat based on the image recognition technology. The predicted hull state can be obtained by training a state generation model according to the historical hull's sea surface data and the corresponding hull state during operation, and inputting the sea surface data into the state generation model to obtain the corresponding predicted hull state.

[0101] Here, the state generation model can be a conventional object detection network. As long as the sea surface data is input into the state generation model, the corresponding predicted hull state can be obtained. Specifically, the object detection network can be selected from RFCN / SSD / RCNN / FastRCNN / FasterRCNN / SPPNet / DPM / OverFeat / YOLO, etc.

[0102] Referring to Figure 1 , the embodiment of the present application also discloses a seawater discharge monitoring system, which is applied to a coastal rowing boat. The coastal rowing boat includes an attitude detection device and a seawater detection device. The attitude detection device is arranged on the deck of the rowing boat hull 41, and the seawater detection device is arranged inside the rowing boat hull 41. The coastal rowing boat includes a drainage airbag 10, and the drainage airbag 10 is arranged at the tail of the hull. Moreover, the drainage airbag 10 includes an inflated state and a drainage state, and the initial state of the drainage airbag 10 is the inflated state.

[0103] As Figure 5 shown, the seawater discharge monitoring system includes an attitude acquisition module 50, a data judgment module 60, and a data processing module 70. The data judgment module 60 is network-connected to the attitude acquisition module 50, and the data judgment module 60 is network-connected to the data processing module 70.

[0104] The attitude acquisition module 50 acquires hull data based on the attitude detection device and obtains the hull attitude according to the hull data.

[0105] The data judgment module 60 is used to judge whether the hull attitude is in a backward state.

[0106] If it is determined that the hull attitude is in a backward tilt state, the data processing module 70 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.

[0107] The data judgment module 60 is also used to judge whether the monitoring data is valid data, and the valid data indicates that accumulated water to be drained is detected inside the hull of the rowing boat.

[0108] If it is determined that the monitoring data is valid data, the data processing module 70 is used to generate a drainage opening signal, and based on the drainage opening signal, control the drainage airbag 10 to enter the drainage state from the inflated state, so as to drain the accumulated water to be drained.

[0109] Among them, the hull data, hull attitude, seawater monitoring signal, monitoring data, and drainage opening signal are the same as or similar to those in the seawater drainage monitoring method described above, and will not be described in detail here.

[0110] Other functions executed by the attitude acquisition module 50, data judgment module 60, and data processing module 70, as well as the technical details of each function, are the same as or similar to the corresponding features in the seawater drainage monitoring method described above, so they will not be elaborated here.

[0111] The embodiment of the present application also discloses a drainage structure.

[0112] Referring to Figure 1 and Figure 2 , the drainage structure includes a drainage airbag 10, the drainage airbag 10 is arranged at the tail of the rowing boat, and a flexible layer 30 is arranged on the surface of the drainage airbag 10.

[0113] A blower device 20, the blower device 20 is arranged above the hull, and the air outlet of the blower device 20 faces the drainage airbag 10.

[0114] 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 rowing boat is inclined downward from the hull towards the tail, and the highest point at the tail is higher than the hull, so as to prevent seawater from entering the hull from the tail. The blower device 20 is installed on the hull, and the blower device 20 includes a fan, an air outlet, and a driving motor. The air outlet faces the stern. When the processor generates a drainage opening signal, it will control the driving motor to start the fan according to the drainage opening signal.

[0115] In one of the embodiments, a plurality of drainage airbags 10 are arranged, and the plurality of drainage airbags 10 are arranged in order from large to small towards the stern 42 of the rowing boat.

[0116] Among them, when the drainage airbag 10 is in the inflated state, the tail of the rowing boat is higher than the hull 41 of the rowing boat. When the drainage airbag 10 is in the drainage state, the tail of the rowing boat unfolds downward along the hull, and the hull 41 of the rowing boat is higher than the tail of the rowing boat.

[0117] In one of the embodiments, the air blowing device 20 is provided with a baffle at the air outlet position, and the baffle moves up and down along the direction perpendicular to the hull 41 of the rowing boat.

[0118] Among them, when the hull attitude is in the backward tilt state, the baffle moves upward along the direction perpendicular to the hull 41 of the rowing boat until the air outlet is directly opposite the drainage airbag 10. When the rowing boat enters the forward tilt state or the parallel state, the baffle moves downward along the direction perpendicular to the hull 41 of the rowing boat until the baffle is clamped with the hull 41 of the rowing boat.

[0119] The embodiment of the present application also discloses a coastal rowing boat, and the coastal rowing boat includes the drainage structure described above.

[0120] The implementation principle is as follows:

[0121] When the athlete is in the driving process, the processor obtains the hull data in real time based on the attitude detection device, and analyzes the hull data obtained in real time to obtain the hull attitude. It is judged whether the hull attitude is in the backward tilt state. If it is determined that the hull attitude is in the backward tilt state, a seawater monitoring signal is generated, and based on the seawater monitoring signal, the seawater detection device is controlled to monitor the hull of the rowing boat to obtain the monitoring data. It is judged whether the monitoring data is valid data. If it is determined that the monitoring data is valid data, a drainage opening signal is generated, and based on the drainage opening signal, the drainage airbag 10 is controlled to enter the drainage state from the inflated state so as to discharge the seawater.

[0122] It should be understood that although the steps in the flowchart of the accompanying drawings are shown in sequence according to the indication of the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps has no strict order limit, and they can be executed in other orders.

[0123] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
