Description

Technical Field

[0001] The present invention relates to the field of balance self-testing, and more particularly to a dragon boat hull balance self-testing device. Background Art

[0002] The dragon boat hull balance self-test device usually refers to a ship inclinometer, which is a device used to measure the tilt state of the ship. Its main purpose is to determine whether the hull is stable. Most balance test devices cannot adjust the position of the counterweight. For example, on a small boat, the small boat sways greatly in the wind and waves, so the detector can easily exceed the range. On a large ship, the influence of wind and waves is small, and it is difficult to produce large swings, making it difficult for the detection device to detect. For example, a ship balance test device with the announcement number CN222682646U increases the detection accuracy of the detection device by adjusting the position of the counterweight pendulum.

[0003] Dragon boats are used in dragon boat races. The balance of the boat is directly related to the results of the race, so it is necessary to perform self-tests on its balance. Currently, the paddling action generates periodic vibrations. Combined with the impact of waves on the boat, these vibrations are transmitted through the boat to the connection between the self-test device and the boat, causing the connection components to gradually fatigue and loosen, thereby affecting the accuracy of the self-test device. This means that it is impossible to monitor the status of the connection components of the self-test device and strengthen them to ensure the accuracy of the balance test data.

[0004] Moreover, during the competition, the waves will splash onto the connecting parts, and the water stains in the small gaps between the connecting parts and the self-test device are difficult to dry. If this continues for a long time, it will cause rust on the self-test device or the connecting parts, and also affect the service life of the self-test device. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dragon boat hull balance self-test device.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a dragon boat hull balance self-test device, comprising a hull and a mounting slot provided above the hull, wherein the interior of the mounting slot is connected to a self-test chassis via a connecting component, and a control panel is fixedly provided above the self-test chassis;

[0007] The connecting component includes a baffle rotatably connected to the inner wall of the mounting groove, and both side walls of the baffle are connected to a connecting frame. Grooves are provided on the outer walls opposite to each other of the two groups of connecting frames, and air bags are provided inside the grooves. A micro air pump is provided above the mounting groove, and the output end of the micro air pump is connected to a delivery main pipe. The output end of the delivery main pipe is connected to two side delivery pipes, and the output ends of the side delivery pipes extend into the connecting frame and are in communication with the air bags. A control valve 1 is provided on the outer wall of the side delivery pipe.

[0008] The output end of the main delivery pipe is also connected to the middle delivery pipe. A dredging pipe is longitudinally opened inside the baffle, and the dredging pipe is connected to the middle delivery pipe. Drying grooves are opened on both side walls of the baffle close to the connection frame.

[0009] Furthermore, multiple groups of upper drying pipes and multiple groups of lower drying pipes are respectively provided on the upper and lower sides of the drying tank, and the multiple groups of upper drying pipes and multiple groups of lower drying pipes are all connected to the dredging pipe, and a control valve 2 is provided on the outer wall of the middle conveying pipe.

[0010] Furthermore, the cross section of the connecting frame is U-shaped, and multiple groups of convex strips are arranged evenly above and below the U-shaped groove of the connecting frame, and the output ends of the upper drying tube and the lower drying tube are both arranged towards the convex strips.

[0011] Furthermore, the control panel includes a processor, a parameter acquisition module and a component control terminal;

[0012] The parameter acquisition module is used to collect the displacement value of the baffle during the dragon boat race, where the displacement value is expressed as the displacement value of the baffle relative to the installation slot;

[0013] When the displacement value is not stable at zero, a fixed signal is generated and sent to the component control end through the processor. After receiving the fixed signal, the component control end immediately controls the micro air pump to work, opens control valve 1, and closes control valve 2. Gas enters the airbag through the side delivery pipe. The two sets of airbags are continuously filled, thereby increasing the friction between the connection frame and the mounting groove;

[0014] When the displacement value stabilizes at zero, no signal is generated.

[0015] Furthermore, a support plate is provided on the top wall of the mounting groove away from the baffle, and the top of the support plate contacts the bottom of the self-test chassis.

[0016] Furthermore, a rubber strip is installed above the support plate, and a fixing plate is fixedly connected to the side wall of the installation groove away from the baffle, and the fixing plate is in conflict with the self-test chassis.

[0017] Furthermore, a bracket is fixedly installed above the self-inspection chassis, a fan-shaped plate is provided above the bracket, and a pendulum is rotatably provided on the fan-shaped plate.

[0018] Furthermore, alarm lights are symmetrically installed on both sides of the top of the fan-shaped plate, and multiple groups of drainage holes are opened on the side of the installation groove opposite to the hull.

[0019] Technical effects and advantages of the present invention:

[0020] The present invention monitors the status of the connecting components of the self-inspection device, that is, using the baffle as a reference, the parameter acquisition module obtains the displacement value of the baffle relative to the installation slot, and judges whether the displacement occurs by judging whether the displacement value is stable at zero. When the baffle is displaced, it indicates that the fixation of the self-inspection device is loose. The component control end controls the operation of the micro air pump based on the received fixed signal, and the gas enters the interior of the air bag and fills it, thereby increasing the friction between the connection frame and the installation slot, making the self-inspection device stable, and improving the accuracy of the self-inspection device in detecting the hull. When the self-inspection device is disassembled, the convex strips and crevices of the connecting components are dried by deflating the air bag or operating the micro air pump, thereby reducing rust and extending the service life of the self-inspection device.

[0021] The present invention inserts the bottom of the self-inspection chassis into the two connecting frames, and limits the self-inspection chassis by the convex strips on the connecting frames. After the installation is completed, the angle of the baffle is rotated to install it into the inside of the installation groove, and the other side of the self-inspection chassis is limited and engaged by the stop strip, so that the installation of the self-inspection device can be completed quickly. The self-inspection chassis is pulled upward with force so that there is an angle between the two connecting frames and the installation groove, and then the self-inspection chassis is pulled outward to complete the disassembly of the self-inspection device, thereby improving the convenience of installation and disassembly of the self-inspection device.

[0022] The present invention is achieved by symmetrically arranging two groups of infrared sensors above the fan-shaped plate, and the infrared sensors are located at the critical point between the excess range and the stable range on the fan-shaped plate. Once the swing of the pendulum exceeds the limit, the infrared sensor immediately obtains and generates an early warning signal, and transmits the early warning signal to the control panel through the processor. The alarm light is controlled to flash by the control panel, which can more intuitively achieve the purpose of early warning and ensure the stability of the dragon boat's paddling.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-9 As shown, the paddling action in the prior art generates periodic vibrations, and the impact force of the waves on the hull is transmitted through the hull to the connection between the self-test device and the hull, causing the connection parts to gradually fatigue and loosen, thereby affecting the self-test accuracy of the self-test device. This problem can be solved by the following solution:

[0035] In this embodiment, a dragon boat hull balance self-test device includes a hull 1 and a mounting slot 3 provided above the hull 1 for mounting the self-test device. The interior of the mounting slot 3 is connected to a self-test chassis 5 via a connecting component. A control panel 7 is fixedly provided above the self-test chassis 5.

[0036] The connecting component includes a baffle 61 rotatably connected to the inner wall of the mounting groove 3. Connecting frames 63 are symmetrically fixedly connected to both side walls of the baffle 61. Grooves are provided on the opposite outer walls of the two sets of connecting frames 63. Air bags 64 for reinforcing the self-test device are provided inside the grooves. A micro air pump 65 is provided above the mounting groove 3. The output end of the micro air pump 65 is connected to a delivery main pipe 67. The output end of the delivery main pipe 67 is connected to two side delivery pipes 68. The output ends of the side delivery pipes 68 extend into the connecting frame 63 and are in communication with the air bags 64. A control valve 69 is provided on the outer wall of the side delivery pipe 68.

[0037] Insert the bottom of the self-test chassis 5 into the two connecting frames 63, and use the convex strips 610 on the connecting frames 63 to limit the self-test chassis 5. After the installation is completed, rotate the angle of the baffle 61 and install it inside the installation groove 3, and use the stop bar to limit the other side of the self-test chassis 5. When removing, pull the self-test chassis 5 upward with force so that there is an angle between the two connecting frames 63 and the installation groove 3, and then pull the self-test chassis 5 outward to complete the removal of the self-test device.

[0038] See also Figure 3-Figure 6 As shown, the output end of the main delivery pipe 67 is also connected to the middle delivery pipe 66. A dredge pipe 84 is further longitudinally opened inside the baffle 61, and the dredge pipe 84 is connected to the middle delivery pipe 66. Drying grooves 81 are opened on both side walls of the baffle 61 near the connection frame 63. The upper and lower sides of the drying groove 81 are respectively opened with multiple groups of upper drying pipes 83 and multiple groups of lower drying pipes 82. The multiple groups of upper drying pipes 83 and multiple groups of lower drying pipes 82 are all connected to the dredge pipe 84. A control valve 2 is provided on the outer wall of the middle delivery pipe 66.

[0039] Then the micro air pump 65 is controlled to work and the control valve 2 is opened. The gas enters the upper drying tube 83 and the lower drying tube 82 through the middle delivery pipe 66 and the dredging pipe 84, and is blown dry at the convex strips 610 to avoid water stains remaining in the tiny gaps and extend the service life of the self-test device.

[0040] See also Figure 4-Figure 8 As shown, the cross section of the connecting frame 63 is U-shaped, and multiple groups of ridges 610 are arranged evenly above and below the U-shaped groove of the connecting frame 63. The output ends of the upper drying tube 83 and the lower drying tube 82 are both arranged toward the ridges 610. It should be supplemented here that a rubber layer is provided above the ridges 610 to increase friction and reduce vibration.

[0041] See also Figure 1-Figure 3 As shown, a bracket 4 is fixedly mounted above the self-test chassis 5, and a fan-shaped plate 2 is provided above the bracket 4. A pendulum is rotatably provided on the fan-shaped plate 2. It should be noted that a cover is provided on the outer side of the fan-shaped plate 2 to provide waterproof protection for the fan-shaped plate 2, and the control panel 7 also has a waterproof effect.

[0042] See also Figure 3-Figure 4 As shown, a support plate 62 is provided on the top wall of the mounting groove 3 away from the baffle 61, the top of the support plate 62 contacts the bottom of the self-test chassis 5, and a rubber strip is installed above the support plate 62. A fixing plate 11 is fixedly connected to the side wall of the mounting groove 3 away from the baffle 61, and the fixing plate 11 conflicts with the self-test chassis 5;

[0043] See also Figure 9As shown, warning lights 10 are symmetrically installed on both sides of the top of the sector plate 2, and multiple sets of drainage holes 9 are opened on the side of the installation groove 3 opposite to the hull 1. When water waves enter the interior of the installation groove 3, they are discharged through the drainage holes 9;

[0044] Example 2: Please refer to Figures 1-9 As shown, the control panel 7 includes a processor, a parameter acquisition module and a component control terminal. The parameter acquisition module is used to collect the displacement value of the baffle 61 during the dragon boat race. The displacement value is expressed as the displacement value of the baffle 61 relative to the mounting slot 3. The displacement value is obtained by a displacement sensor installed on the side wall of the baffle 61.

[0045] When the displacement value is not stable at zero, it means that the baffle 61 is displaced relative to the installation slot 3, that is, the self-test device above the baffle 61 is shaking in the installation slot 3, and the larger the displacement value is, the more unstable the baffle 61 is in the installation slot 3. A fixed signal is generated and sent to the component control end through the processor. After receiving the fixed signal, the component control end immediately controls the micro air pump 65 to work.

[0046] Control the air pump to work, open control valve 1 69, close control valve 2, and allow gas to flow into the airbag 64 through the side delivery pipe 68, continuously filling the airbag 64 and thereby increasing the friction between the connecting frame 63 and the mounting slot 3, thereby preventing the self-test device from shaking and affecting the accuracy of the balance self-test. After the filling is completed, close control valve 1 69 and the air pump;

[0047] When the dragon boat race is finished, the control valve 1 69 and the control valve 2 are opened, and the gas inside the airbag 64 enters the middle delivery pipe 66 through the side delivery pipe 68, and is finally discharged through the upper drying pipe 83 and the lower drying pipe 82 to assist in drying the bottom of the self-test device;

[0048] When the displacement value is stable at zero, no signal is generated, indicating that the baffle 61 has not moved relative to the mounting groove 3, that is, the self-test device is firmly installed in the mounting groove 3, ensuring the self-test accuracy of the self-test device;

[0049] It should be noted that two sets of infrared sensors are symmetrically arranged above the fan-shaped plate 2, and the infrared sensors are located at the critical point between the excess range and the stable range on the fan-shaped plate 2. Once the swing of the pendulum exceeds the limit, the infrared sensor immediately obtains and generates an early warning signal, which is transmitted to the control panel 7 through the processor. The control panel 7 controls the alarm light 10 to flash, which can more intuitively serve the purpose of early warning and ensure the stability of the dragon boat hull.

[0050] The present invention is combined with Example 1 and Example 2 to know that:

[0051] By monitoring the status of the connecting components of the self-test device, that is, taking the baffle 61 as a reference, the displacement value of the baffle 61 relative to the mounting groove 3 is obtained through the parameter acquisition module, and by checking whether the displacement value is stable at zero, it is determined whether it has displaced. When the baffle 61 is displaced, it indicates that the fixation of the self-test device is loose. The component control end controls the micro air pump 65 to operate according to the received fixation signal, and the gas enters the interior of the air bag 64 and fills it, thereby increasing the friction between the connecting frame 63 and the mounting groove 3, making the self-test device stable and improving the accuracy of the self-test device in detecting the hull 1. When the self-test device is disassembled, the slits of the convex strips 610 of the connecting components are dried by deflating the air bag 64 or operating the micro air pump 65, thereby reducing rust and extending the service life of the self-test device.

[0052] Working principle:

[0053] Installation: Insert the bottom of the self-test chassis 5 into the two connecting frames 63, and use the convex strips 610 on the connecting frames 63 to limit the self-test chassis 5. After installation, rotate the angle of the baffle 61 and install it into the inside of the installation slot 3. Use the stop bar to limit the other side of the self-test chassis 5, so that the self-test device can be installed quickly.

[0054] Disassembly: Pull the self-test chassis 5 upward with force, so that there is an angle between the two connecting frames 63 and the mounting slot 3, and then pull the self-test chassis 5 outward to complete the disassembly of the self-test device. Through the two steps of installation and disassembly, it can be seen that the installation and disassembly of the self-test device are relatively convenient, which improves the practicality of the use of the self-test device.

[0055] Rust removal: Control the micro air pump 65 to work and open the control valve 2. The gas enters the upper drying tube 83 and the lower drying tube 82 through the middle delivery pipe 66 and the dredging pipe 84, and blows the raised strips 610 to dry them to prevent water stains from remaining in the tiny gaps and causing rust on the bottom of the self-test device.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, many modifications and variations are possible based on the contents of this specification.
