Description

Technical Field

[0001] The present invention relates to the field of balance self-detection tests, and more specifically, the present invention relates to a self-checking device for the balance of a dragon boat hull. Background Art

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

[0003] A dragon boat is a boat used in dragon boat races. The balance of the hull is directly related to the race result, so it is necessary to self-check its balance. At present, the rowing action will generate periodic vibrations, and together with the impact force of the waves on the hull, it will be transmitted to the connection between the self-checking device and the hull through the hull, causing the connection components to gradually become fatigued and loose, thereby affecting the self-checking accuracy of the self-checking device, that is, the state supervision and reinforcement treatment of the connection components of the self-checking device cannot be carried out to ensure the accuracy of the balance detection data; Moreover, during the race, the spray will splash onto the connection components, and the water stains in the small gaps where the connection components are connected to the self-checking device are difficult to dry. Over time, it will cause rust on the self-checking device or the connection components, and also affect the service life of the self-checking device. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-checking device for the balance of a dragon boat hull.

[0005] To achieve the above object, the present invention provides the following technical solution: A self-checking device for the balance of a dragon boat hull, including a hull and an installation groove opened above the hull. The inside of the installation groove is connected with a self-checking chassis through a connection component, and a control panel is fixedly arranged above the self-checking chassis; The connection component includes a baffle rotatably connected to the inner wall of the installation groove. Connection frames are connected to both side walls of the baffle. Grooves are opened on the outer walls of the two connection frames facing away from each other. An airbag is arranged inside the groove. A micro air pump is arranged above the installation groove. The output end of the micro air pump is connected with a main delivery pipe. The output end of the main delivery pipe is connected with two side delivery pipes. The output end of the side delivery pipe extends into the connection frame and is communicated with the airbag. A control valve I is arranged on the outer wall of the side delivery pipe; The output end of the main conveying pipe is also connected with a middle conveying pipe. A dredging pipe is longitudinally arranged inside the baffle. The dredging pipe is communicated with the middle conveying pipe. Drying grooves are arranged on both side walls of the baffle close to the connecting frame.

[0006] Furthermore, a plurality of upper drying pipes and a plurality of lower drying pipes are respectively arranged on the upper and lower sides of the drying groove. The plurality of upper drying pipes and the plurality of lower drying pipes are all communicated with the dredging pipe. A control valve II is arranged on the outer wall of the middle conveying pipe.

[0007] Furthermore, the cross section of the connecting frame is U-shaped on the side. A plurality of convex strips are arranged in an aligned manner above and below the U-shaped groove of the connecting frame. The output ends of the upper drying pipes and the lower drying pipes are all arranged towards the convex strips.

[0008] Furthermore, the control panel includes a processor, a parameter acquisition module and a component control end; The parameter acquisition module is used to collect the displacement value of the baffle during the dragon boat race. The displacement value is expressed as the numerical value of the displacement of the baffle relative to the installation groove; 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 the control valve I, closes the control valve II, and the gas enters the airbag through the side conveying pipe. The two airbags are continuously filled, thereby increasing the friction force between the connecting frame and the installation groove; When the displacement value is stable at zero, no signal is generated.

[0009] Furthermore, a support plate is arranged on the top wall of the installation groove away from the baffle. The top of the support plate is in contact with the bottom of the self-checking chassis.

[0010] Furthermore, a rubber strip is installed above the support plate. A fixing plate is fixedly connected to the side wall of the installation groove away from the baffle. The fixing plate abuts against the self-checking chassis.

[0011] Furthermore, a support is fixedly installed above the self-checking chassis. A sector plate is arranged above the support. A pendulum is rotatably arranged on the sector plate.

[0012] Furthermore, alarm lights are symmetrically installed on both sides of the top of the sector plate. A plurality of drain holes are arranged on the side of the installation groove opposite to the hull.

[0013] The technical effects and advantages of the present invention: The present invention monitors the state of the connection components of the self-checking device. That is, taking the baffle as a reference object, through the parameter acquisition module, the value of the displacement of the baffle relative to the installation groove is obtained. By judging whether the displacement value is stable at zero, it is determined whether displacement occurs. When the baffle is displaced, it indicates that the fixation of the self-checking device is loose. The component control end controls the micro air pump to work according to the received fixation signal. Gas enters the interior of the airbag and fills it, increasing the friction between the connection frame and the installation groove, making the self-checking device stable, improving the accuracy of the self-checking device when detecting the hull, and when disassembling the self-checking device, through the deflation of the airbag or the work of the micro air pump, the convex strip and slit of the connection component are dried, reducing rust and extending the service life of the self-checking device.

[0014] In the present invention, the bottom of the self-checking chassis is inserted into two connection frames, and the self-checking chassis is limited by the convex strips on the connection frames. After the installation is completed, the angle of the baffle is rotated and it is installed into the interior of the installation groove, and the other side of the self-checking chassis is limited and clamped by the resisting strip, so that the installation of the self-checking device can be quickly completed. When the self-checking chassis is pulled upward forcefully, after an angle exists between the two connection frames and the installation groove, and then the self-checking chassis is pulled outward to complete the disassembly of the self-checking device, improving the convenience of the installation and disassembly of the self-checking device.

[0015] In the present invention, two groups of infrared sensors are symmetrically arranged above the sector plate, and the infrared sensors are located at the critical point between the over-range and stable ranges on the sector plate. Once the swing of the pendulum is over-range, the infrared sensors immediately acquire and generate a warning signal, and the warning signal is transmitted to the control panel through the processor, and the control panel controls the alarm lamp to flash, which can more intuitively achieve the purpose of warning and ensure the stability of the rowing of the dragon boat hull.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: Please refer to Figures 1-9 As shown, for the problem that the rowing action in the prior art will generate periodic vibrations, and coupled with the impact force of the waves on the hull, it will be transmitted to the connection part between the self-checking device and the hull through the hull, resulting in the gradual fatigue and loosening of the connection components, thereby affecting the self-checking accuracy of the self-checking device, the following solutions can be adopted: In this embodiment, a self-checking device for the balance of a dragon boat hull includes a hull 1 and an installation groove 3 opened above the hull 1 and used for installing the self-checking device. The inside of the installation groove 3 is connected with a self-checking chassis 5 through a connection component, and a control panel 7 is fixedly arranged above the self-checking chassis 5; The connection component includes a baffle 61 rotatably connected to the inner wall of the installation groove 3. Symmetrically fixed connection frames 63 are fixedly connected to both side walls of the baffle 61. Grooves are opened on the outer walls of the two groups of connection frames 63 facing away from each other. An airbag 64 for strengthening the self-checking device is arranged inside the grooves. A micro air pump 65 is arranged above the installation groove 3. The output end of the micro air pump 65 is connected with a conveying main pipe 67. The output end of the conveying main pipe 67 is connected with two side conveying pipes 68. The output ends of the side conveying pipes 68 extend into the connection frame 63 and are communicated with the airbag 64. A control valve I 69 is arranged on the outer wall of the side conveying pipe 68; Then insert the bottom of the self-checking chassis 5 into the two connecting frames 63, and limit the self-checking chassis 5 through the protruding strips 610 on the connecting frames 63. After the installation is completed, rotate the baffle 61 and install it inside the installation groove 3, and limit and engage the other side of the self-checking chassis 5 through the resisting strip. When disassembling, pull the self-checking chassis 5 upward forcefully until there is an angle between the two connecting frames 63 and the installation groove 3, and then pull the self-checking chassis 5 outward to complete the disassembly of the self-checking device; Please refer to Figures 3-6 As shown, the output end of the conveying main pipe 67 is also connected to the middle conveying pipe 66. A dredging pipe 84 is longitudinally opened inside the baffle 61. The dredging pipe 84 is communicated with the middle conveying pipe 66. Drying grooves 81 are opened on both side walls of the baffle 61 close to the connecting frame 63. A plurality of upper drying pipes 83 and a plurality of lower drying pipes 82 are respectively opened on the upper and lower sides of the drying groove 81. The plurality of upper drying pipes 83 and the plurality of lower drying pipes 82 are both communicated with the dredging pipe 84. A control valve II is arranged on the outer wall of the middle conveying pipe 66; Then control the micro air pump 65 to work and open the control valve II. The gas enters the upper drying pipe 83 and the lower drying pipe 82 through the middle conveying pipe 66 and the dredging pipe 84, and blows and dries the protruding strip 610 to avoid water stains remaining in the tiny gaps and extend the service life of the self-checking device; Please refer to Figures 4-8 As shown, the cross-section of the connecting frame 63 is side U-shaped, and a plurality of groups of protruding strips 610 are arranged in rows above and below the U-shaped groove of the connecting frame 63. The output ends of the upper drying pipe 83 and the lower drying pipe 82 are both arranged towards the protruding strip 610. Here, it should be added that: a rubber layer is arranged above the protruding strip 610 to play a role in increasing friction and buffering vibration; Please refer to Figures 1-3 As shown, a support 4 is fixedly installed above the self-checking chassis 5. A sector plate 2 is arranged above the support 4. A pendulum is rotatably arranged on the sector plate 2. Here, it should be added that a housing for waterproof protection is arranged outside the sector plate 2, and the control panel 7 also has the function of waterproofing; Please refer to Figures 3-4 As shown, a support plate 62 is arranged on the top wall of the installation groove 3 away from the baffle 61. The top of the support plate 62 is in contact with the bottom of the self-checking 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 installation groove 3 away from the baffle 61. The fixing plate 11 abuts against the self-checking chassis 5; Please refer to Figure 9 As shown, warning lights 10 are symmetrically installed on both sides of the top of the sector plate 2. A plurality of drainage holes 9 are opened on the side of the installation groove 3 opposite to the hull 1. When the water wave enters the installation groove 3, it is discharged through the drainage holes 9; Embodiment 2: Please refer to Figures 1-9As shown in the figure, 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 represents the numerical value of the displacement of the baffle 61 relative to the installation groove 3, which is obtained through a displacement sensor. The displacement sensor is installed on the side wall of the baffle 61; When the displacement value is not stabilized at zero, it indicates that the baffle 61 has displaced relative to the installation groove 3, that is, the self-checking device above the baffle 61 has shaken in the installation groove 3. The larger the displacement value, the more unstable the baffle 61 is in the installation groove 3. A fixed signal is generated and sent to the component control terminal through the processor. After receiving the fixed signal, the component control terminal immediately controls the micro air pump 65 to work; Control the air pump to work, open the control valve I 69, close the control valve II. The gas enters the airbag 64 through the side delivery pipe 68, continuously fills the airbag 64, thereby increasing the friction between the connecting frame 63 and the installation groove 3, avoiding the shaking of the self-checking device and affecting the accuracy of the balance self-check. After the filling is completed, close the control valve I 69 and the air pump; After the dragon boat race is completed, open the control valve I 69 and the control valve II. The gas inside the airbag 64 enters the middle delivery pipe 66 through the side delivery pipe 68 and finally is discharged through the upper drying pipe 83 and the lower drying pipe 82 to assist in drying the bottom of the self-checking device; When the displacement value is stabilized at zero, no signal is generated, indicating that the baffle 61 has not displaced relative to the installation groove 3, that is, the self-checking device is firmly installed in the installation groove 3, ensuring the self-checking accuracy of the self-checking device; It should be supplemented here that: there are two groups of infrared sensors symmetrically arranged above the sector plate 2, and the infrared sensors are located at the critical point between the over-range and stable ranges on the sector plate 2. Once the swing of the pendulum exceeds the limit, the infrared sensors immediately acquire and generate a warning signal, and transmit the warning signal to the control panel 7 through the processor. The control panel 7 controls the alarm lamp 10 to flash, which can more intuitively achieve the purpose of warning and ensure the stability of the dragon boat hull rowing; It can be seen from the combination of Embodiment 1 and Embodiment 2 of the present invention that: By monitoring the status of the connection components of the self-checking device, that is, taking the baffle 61 as a reference object, the parameter acquisition module obtains the value of the displacement of the baffle 61 relative to the installation groove 3. By judging whether the displacement value is stable at zero, it is determined whether displacement occurs. When the baffle 61 is displaced, it indicates that the fixation of the self-checking device is loose. The component control end controls the micro air pump 65 to work according to the received fixation signal. Gas enters the inside of the airbag 64 and fills it, increasing the friction between the connection frame 63 and the installation groove 3, making the self-checking device stable, improving the accuracy of the self-checking device for detecting the hull 1, and when disassembling the self-checking device, by deflating the airbag 64 or the micro air pump 65 working, drying the fine gaps of the convex strips 610 of the connection components, reducing rust and extending the service life of the self-checking device; Working principle: Installation: Insert the bottom of the self-checking chassis 5 into the two connection frames 63, and limit the self-checking chassis 5 through the convex strips 610 on the connection frames 63. After the installation is completed, rotate the angle of the baffle 61 and install it into the installation groove 3, and limit and engage the other side of the self-checking chassis 5 through the resisting strip, so that the installation of the self-checking device can be quickly completed; Disassembly: Pull the self-checking chassis 5 upward forcefully, so that there is an angle between the two connection frames 63 and the installation groove 3, and then pull the self-checking chassis 5 outward to complete the disassembly of the self-checking device; From the two steps of installation and disassembly, it can be seen that the installation and disassembly of the self-checking device are relatively convenient, improving the practicability of the use of the self-checking device; Rust removal: Control the micro air pump 65 to work and open the second control valve. Gas enters the upper drying pipe 83 and the lower drying pipe 82 through the middle conveying pipe 66 and the dredging pipe 84, and blows and dries the convex strips 610 to avoid water stains remaining in the tiny gaps and causing rust at the bottom of the self-checking device.
