Description

Technical Field

[0001] This invention belongs to the field of rowing, and more specifically, relates to a wide-body recreational single rowing boat. Background Technology

[0002] Rowing is a water sport in which one or more rowers sit in a boat, facing away from the direction the boat is going, and use their muscle strength to propel the boat forward by paddling with oars and oarlocks using a simple lever action. Nowadays, rowing is also used for everyday leisure and recreation.

[0003] During modern rowing, the reciprocating motion of the oars stirs up water, some of which enters the boat and accumulates inside. If too much water accumulates inside, it will affect the boat's normal movement, increase its weight, and make it more prone to sinking, posing a danger to the rowers. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wide-body recreational single-person racing boat that can discharge the water accumulated inside the racing boat.

[0005] The present invention relates to a wide-body recreational single-person racing boat, comprising a hull, pedals rotatably connected to the hull, and a sliding seat slidably connected to the hull; a foot pedal area for mounting the pedals is provided on the hull near the stern; an open compartment is provided on the hull above the stern; and an inclined guide surface is provided at one end of the foot pedal area near the open compartment.

[0006] As a further improvement of the present invention, a balancing mechanism is provided on both sides of the hull along the width direction; the balancing mechanism includes a sealing plate rotatably connected to the lower part of the hull and a retractable corrugated sleeve installed between the sealing plate and the outer wall of the hull.

[0007] As a further improvement of the present invention, the balancing mechanism further includes a plurality of support plates that rotate coaxially with the sealing plate; each of the support plates is installed inside the corrugated sleeve.

[0008] As a further improvement of the present invention, a transmission belt is installed in the hull along the length of the hull; the transmission belt is connected to the sealing plate; and a synchronous plug that can engage with the transmission belt and thus drive the transmission belt to move is longitudinally slidably connected on the slide.

[0009] As a further improvement of the present invention, the pedal includes two symmetrically arranged foot pedal halves; each foot pedal halves is slidably connected to the hull body along the width direction of the hull; a drive slide rod for driving the synchronous plug to move longitudinally is slidably connected inside the slide block along the width direction of the hull; the foot pedal halves and the drive slide rod move synchronously along the width direction of the hull.

[0010] As a further improvement of the present invention, a pump body is installed in the hull for pumping water retained in the foot pedal area into the outside; the pump body is connected to a transmission belt.

[0011] As a further improvement of the present invention, a drive slide plate is fixedly connected to the upper end of the transmission belt; a rotating gear is fixedly connected to the sealing plate coaxially; and a sliding rack capable of meshing with the rotating gear is slidably connected longitudinally on the drive slide plate.

[0012] As a further improvement of the present invention, a switching mechanism for driving the longitudinal movement of the sliding rack is installed in the hull; the switching mechanism includes a lifting frame that is longitudinally slidably connected to the hull and abuts against the lower end of the sliding rack, a swing plate that is rotatably connected to the lower part of the hull and is driven to rotate by the water flow, and an eccentric plate that is fixedly connected to the swing plate for driving the longitudinal movement of the lifting frame.

[0013] As a further improvement of the present invention, a counterweight is fixedly connected to the lower side of the swing plate.

[0014] As a further improvement of the present invention, the end of the sealing plate away from the corrugated sleeve is an inclined guide wall.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up an open compartment, the water in the foot area can leave the hull under its own inertia when the hull moves at high speed, and the open compartment is concave as a whole, which can reduce wind resistance during movement.

[0016] In the initial learning stages, students often have poor control over the boat's balance, making it easy for the boat to capsize and endanger their lives. This solution addresses this by controlling the rotation of the sealing plate, altering the area of ​​the extended corrugated sleeve. Initially, the sleeve is extended to its maximum area to facilitate balance control. As students become more proficient, the extended area is reduced to adapt to their learning pace, allowing them to gradually master balance. Finally, when the sleeve fully retracts into the boat, the student is completely comfortable with the hull. Throughout this process, the chance of capsizing is minimized, significantly improving student safety. This solution also provides enhanced safety for solo recreational activities.

[0017] The pedal in this design can not only assist in the movement of the boat, but also control the movement of the synchronizing block, thereby controlling the transmission relationship between the slide and the transmission belt.

[0018] The sliding block in this design can both assist in the movement of the hull and drive the transmission belt.

[0019] The transmission belt in this design can not only drive the sealing plate to rotate, thereby causing the corrugated sleeve to extend and retract, but also control the pump body to discharge water from the foot pedal area.

[0020] This solution utilizes the thrust of the water flow to rotate the swing plate, thereby controlling the transmission relationship between the drive belt and the sealing plate, preventing the sealing plate from rotating along with the water in the foot pedal area, which would affect the normal use of the boat.

[0029] Specific Implementation Example 1: Please refer to... Figure 1-12 A wide-body recreational single-person racing boat includes a hull 1, a pedal 21 rotatably connected within the hull 1, and a slide seat 31 slidably connected within the hull 1. The slide seat 31 is slidably connected to the hull 1 along its length. A sliding area 12 is provided on the hull 1. A slide rail 13 is provided at the upper end of the sliding area 12. A track connecting seat 313 slidably connected to the slide rail 13 is provided at the lower end of the slide seat 31. A foot pedal area 11 for mounting the pedal 21 is provided on the hull 1 near the stern. An open compartment 15 is provided on the hull 1 above the stern. An inclined guide surface 16 is provided at one end of the foot pedal area 11 near the open compartment 15.

[0030] The height of the sliding area 12 is higher than that of the foot pedal area 11. The hull 1 can be divided into a bow, a stern, and a body located between the bow and the stern along its length. The sliding area 12 and the foot pedal area 11 are located on the body.

[0031] A pedal link 14 is fixedly connected above the foot pedal area 11; the pedal 21 is rotatably connected to the pedal link 14; and a strap is installed on the surface of the pedal 21.

[0032] When the hull 1 moves at a relatively high speed, the water entering the hull 1 will gather in the foot pedal area 11, and under the action of inertia, it will flow along the guide surface 16 to the upper end of the open compartment 15, and finally flow out of the hull 1 along the open compartment 15, thus preventing water from accumulating inside the hull 1.

[0033] The hull 1 is provided with a boat frame 10 on each side along the width direction; the boat frame 10 is detachably connected to the propeller 8.

[0034] The hull 1 is provided with balancing mechanisms 5 on both sides along the width direction; the balancing mechanism 5 includes a sealing plate 54 rotatably connected to the lower part of the hull 1 and a retractable corrugated sleeve 51 installed between the sealing plate 54 and the outer wall of the hull 1.

[0035] The corrugated sleeve 51 extends into a fan shape and contracts into a rectangle. The corrugated sleeve 51 is made of plastic. When the sealing plate 54 rotates to the outside of the hull 1, the corrugated sleeve 51 extends, thereby increasing the overall width of the hull 1. When the hull 1 has a tendency to capsize, the water will generate greater buoyancy on the hull 1, thereby reducing the probability of the hull 1 capsizing.

[0036] By adjusting the rotation angle of the sealing plate 54, the area of ​​the corrugated sleeve 51 after extension is controlled so that the trainees can adapt to the current progress and it is not easy to flip during the trainees' learning process.

[0037] The balancing mechanism 5 also includes a plurality of support plates 52 that rotate coaxially with the sealing plate 54; each of the support plates 52 is installed inside the corrugated sleeve 51.

[0038] The upper end of the support plate 52 is coaxially provided with a fan-shaped connecting groove 521; the lower end of the support plate 52 is provided with a connecting post 522; for two adjacent support plates 52, the connecting post 522 on the upper support plate 52 is slidably connected in the connecting groove 521 on the lower support plate 52. When one support plate 52 rotates until the connecting post 522 abuts against the side wall of the corresponding connecting groove 521, the two support plates 52 have a certain angle between them, and then the two support plates 52 will rotate synchronously.

[0039] The sealing plate 54 is coaxially provided with a fan-shaped sealing plate groove 541; the sealing plate groove 541 is slidably connected to the connecting column 522 on the support plate 52 located at the upper end of the sealing plate 54, so that when the sealing plate 54 rotates to the outside of the hull 1, the sealing plate 54 can both drive the corrugated sleeve 51 to extend and drive each support plate 52 to rotate in sequence. After rotation, the support plates 52 are distributed in the fan-shaped corrugated sleeve 51, which plays a supporting role for the corrugated sleeve 51 and prevents the corrugated sleeve 51 from fluctuating violently under the impact of water flow.

[0040] A transmission belt 41 is installed inside the hull 1 along the length of the hull 1; the transmission belt 41 is connected to the sealing plate 54; the transmission belt 41 is located below the slide block 31; a synchronous plug 33 is longitudinally slidably connected to the slide block 31, which can engage with the transmission belt 41 and drive the transmission belt 41 to move.

[0041] Two drive belt connecting shafts 410 arranged along the width direction of the hull 1 are rotatably connected inside the hull 1; the drive sleeve 41 is sleeved on the two drive belt connecting shafts 410; an installation cavity 18 is provided on the hull 1 at the bow position; part of the drive belt 41 is located in the sliding area 12, and the other part is located in the installation cavity 18.

[0042] The upper end of the transmission belt 41 is fixedly connected to a card holder 411 below the slide block 31, which can be inserted into the synchronous plug 33; the upper middle part of the card holder 411 is provided with a card slot 412 for accommodating the synchronous plug 33.

[0043] When the synchronizing insert 33 is located in the slot 412, the slide 31 slides, causing the sealing plate 54 to rotate.

[0044] The pedal 21 includes two symmetrically arranged foot pedal halves 211; each foot pedal half 211 is slidably connected to the hull 1 along the width direction of the hull 1; a drive slide rod 32 for driving the synchronous plug 33 to move longitudinally is slidably connected to the slide block 31 along the width direction of the hull 1; the foot pedal half 211 and the drive slide rod 32 move synchronously along the width direction of the hull 1.

[0045] The lower end of the slide block 31 is provided with a longitudinal slide groove 311 that is longitudinally slidably connected to the synchronous plug 33; the slide block 31 is provided with a transverse through groove 312 that is slidably connected to the drive slide rod 32 along the width direction of the hull 1.

[0046] A pedal connecting rod 22 is slidably connected to the hull 1 along the width direction; a drive slide rod 32 is slidably connected to the pedal connecting rod 22 along the length direction of the hull 1, so that the drive slide rod 32 slides relative to the pedal connecting rod 22 along the length direction of the hull 1 and moves synchronously along the width direction of the hull 1.

[0047] The foot pedal half 211 is fixedly connected to the pedal connecting rod 22, and the longitudinal movement of the synchronous plug 33 is controlled by controlling the sliding of the foot pedal half 211.

[0048] The synchronizing plug 33 has inclined synchronizing surfaces 331 at both ends along the width direction of the hull 1; there are two driving slide rods 32, which are symmetrically arranged on both sides of the synchronizing plug 33; the end of the driving slide rod 32 near the synchronizing plug 33 has a driving surface 321 that cooperates with the synchronizing surface 331.

[0049] There are two pedal connecting rods 22, which are symmetrically installed on the hull 1 respectively; one pedal half 211 is fixed to one pedal connecting rod 22, and one pedal connecting rod 22 is engaged with one drive slide rod 32.

[0050] The card holder 411 has inclined lifting walls 413 at both ends of the upper part along the length of the hull 1.

[0051] When the two foot pedal halves 211 move away from each other, the pedal connecting rod 22 drives the drive slide rod 32 to move outward from the hull 1. The synchronous inclined surface 331 separates from the drive inclined surface 321, and the synchronous plug 33 can move freely longitudinally. Under its own weight, it is located at the lower limit position. If the synchronous plug 33 is not inserted into the slot 412 at this time, the slide 31 slides along the length of the hull 1, and the synchronous plug 33 moves synchronously until the synchronous plug 33 abuts against the lifting wall 413. The slide 31 continues to move, and the synchronous plug 33 moves upward along the lifting wall 413. Finally, the synchronous plug 33 will move to the upper end of the slot 411 and be directly opposite the slot 412. Then, the synchronous plug 33 will be inserted into the slot 412 under its own weight, thereby making the slide 31 connected to the transmission belt 41.

[0052] When the two foot pedal halves 211 approach each other to their extreme positions, the pedal connecting rod 22 drives the drive slide rod 32 to move inward to the hull 1. The drive inclined surface 321 abuts against the synchronous inclined surface 331 and forces the synchronous inclined surface 331 to move upward until the synchronous plug 33 moves to the upper extreme position. At this time, the synchronous plug 33 does not cooperate with the transmission belt 41.

[0053] The hull 1 is equipped with a pump body 6 for pumping water retained in the foot pedal area 11 into the outside; the pump body 6 is connected to the transmission belt 41.

[0054] The pump body 6 includes a pump housing 61 fixedly connected inside the hull 1 and located below the transmission belt 41, and a piston body 62 sealed and slidably connected inside the pump housing 61; the sliding direction of the piston body 62 is parallel to the movement direction of the transmission belt 41; a piston drive plate 621 extending to the lower end of the transmission belt 41 is fixedly connected to one side of the piston body 62.

[0055] The lower end of the transmission belt 41 is fixedly connected to two piston push plates 414 that can contact the piston drive plate 621 and drive the piston drive plate 621 to move; the piston drive plate 621 is located between the two piston push plates 414.

[0056] When the slide 31 drives the transmission belt 41 to reciprocate for one cycle, the piston push plate 414 drives the piston drive plate 621 to reciprocate for one cycle, and then the piston body 62 reciprocates to discharge the water in the foot pedal area 11. The stroke of the piston body 62 is less than the stroke of the transmission belt 41.

[0057] The pump casing 61 is equipped with an inlet check valve 611 and an outlet check valve 612; the outlet check valve 612 is connected to the outside of the hull 1; the hull 1 is equipped with a drain pipe 17 that connects the foot pedal area 11 and the inlet check valve 611.

[0058] When the hull 1 moves at a relatively slow speed, the water flowing into the foot pedal area 11 will have difficulty flowing out of the open compartment 15. Therefore, the pump body 6 is used to discharge the water that has entered the foot pedal area 11, without the need for manual cleaning.

[0059] The upper end of the transmission belt 41 is fixedly connected to a drive slide plate 42; the sealing plate 54 is coaxially fixedly connected to a rotating gear 531; and a sliding rack 43 that can mesh with the rotating gear 531 is longitudinally slidably connected to the drive slide plate 42.

[0060] The upper end of the drive slide plate 42 is provided with a longitudinal slide post 421; the sliding rack 43 slides longitudinally on the longitudinal slide post 421.

[0061] A connecting sleeve 542 is coaxially arranged on the sealing plate 54; a rotating column 53, which is coaxially fixed with the connecting sleeve 542, is rotatably connected inside the hull 1; a rotating gear 531 is coaxially arranged on the upper part of the rotating column 53, and the rotating gear 531 is located in the mounting cavity 18.

[0062] When the sliding rack 43 is in the lower limit position, the sliding rack 43 meshes with the rotary gear 531.

[0063] When the sliding rack 43 is in the upper limit position, the sliding rack 43 does not mesh with the rotary gear 531.

[0064] The hull 1 is equipped with a switching mechanism 7 that drives the sliding rack 43 to move longitudinally. The switching mechanism 7 includes a lifting frame 74 that is longitudinally slidably connected to the hull 1 and abuts against the lower end of the sliding rack 43, a swing plate 71 that is rotatably connected to the lower part of the hull 1 and is driven to rotate by the water flow, and an eccentric plate 73 that is fixedly connected to the swing plate 71 for driving the lifting frame 74 to move longitudinally.

[0065] The eccentric plate 73 is located in the mounting cavity 18, and a lifting connecting plate 741 extending to the upper end of the eccentric plate 73 is fixedly connected to the lifting frame 74; when the swing plate 71 rotates, the eccentric plate 73 drives the lifting frame 74 to move up and down.

[0066] The lower end of the hull 1 is provided with a swing groove 19; the swing plate 71 is rotatably connected in the swing groove 19.

[0067] A counterweight 72 is fixedly connected to the lower side of the swing plate 71.

[0068] When the hull 1 moves on the water surface, the water flow generates a thrust on the counterweight 72, causing the counterweight 72 to drive the swing plate 71 to rotate inward toward the swing groove 19. At the same time, the eccentric plate 73 pushes the lifting connecting plate 741, causing the lifting frame 74 to drive the sliding rack 43 to move upward to the limit position.

[0069] When the hull 1 is not moving on the water surface, the water flow will not generate thrust on the counterweight 72. The counterweight 72 moves to below the hull 1 under its own weight, the swing plate 71 rotates synchronously, the eccentric plate 73 drives the lifting connecting plate 741 to move in the opposite direction, and the lifting frame 74 and the sliding rack 43 both move to the lower limit position under their own weight.

[0070] The end of the sealing plate 54 away from the corrugated sleeve 51 is an inclined guide wall 543. When the hull 1 moves, the water flow impacts the guide wall 543. Since the guide wall 543 is inclined, the force of the water flow on the sealing plate 54 in the horizontal direction is reduced, and the sealing plate 54 is prevented from automatically rotating towards the hull 1 due to the impact of the water flow.

[0071] In the initial state, the corrugated sleeve 51 is in a retracted state, the two foot pedal halves 211 are in the side limit position close to each other, and the synchronous plug 33 is separated from the slot 412.

[0072] When in use, the hull 1 is placed in the water, the paddle 8 is installed on the hull frame 10, and then the person sits in the hull 1, puts their feet on the pedal 21 and uses straps to fix their feet on the pedal 21, holds the paddle 8 and lays the paddle 8 flat along the water surface so that the hull 1 remains stable when stationary, the counterweight 72 hangs down naturally, and the sliding rack 43 meshes with the rotating gear 531.

[0073] If it is necessary to increase the overall buoyancy of the hull 1 by using the corrugated sleeve 51, then the following operations should be performed.

[0074] With feet apart, the feet drive the foot pedal half 211 to move to the extreme position outside the hull 1. The foot pedal connecting rod 22 drives the drive slide rod 32 to move synchronously to the outside of the hull 1. The drive slide rod 32 no longer restricts the longitudinal movement of the synchronous plug 33.

[0075] Next, the slide block 31 is moved along the length direction so that the synchronous plug 33 abuts against the lifting wall 413 and moves upward along the lifting wall 413. The synchronous plug 33 moves to the upper end of the card seat 411 and is located directly above the card slot 412. At this time, the synchronous plug 33 is inserted into the card slot 412 under its own gravity, and then the slide block 31 will drive the transmission belt 41 to move.

[0076] When the sliding resistance of the slide block 31 increases, the synchronous plug 33 and the slot 412 are already inserted together. Then, the slide block 31 continues to move, and the slide block 31 drives the synchronous belt 41 to move together. The drive slide plate 42 on the synchronous belt 41 drives the sliding rack 43 to move. The sliding rack 43 drives the rotating column gear 531 to rotate. The rotating column gear 531 drives the sealing plate 54 to rotate outward, and then the corrugated sleeve 51 extends.

[0077] Control the movement distance of the slide block 31 so that the corrugated sleeve 51 extends to a suitable length. Then stop moving the slide block 31, bring your feet together so that the foot pedal half 211 moves to the extreme position where they are close to each other. The foot pedal half 211 drives the pedal connecting rod 22 to move synchronously, driving the slide rod 32 to move inward to the slide block 31, driving the inclined surface 321 to contact the synchronous inclined surface 331, and driving the synchronous plug 33 to move upward until the synchronous plug 33 separates from the slot 412. At this time, the corrugated sleeve 51 is adjusted.

[0078] By rocking the propeller 8 and moving the slide block 31, the hull 1 moves along the water surface.

[0079] If the hull 1 moves at a high speed, the water entering the foot pedal area 11 will flow through the guide surface 16 to the upper end of the open compartment 15 under its own inertia, and then flow out of the hull 1 along the open compartment 15.

[0080] If the hull 1 moves at a low speed, the water entering the foot pedal area 11 will remain in the foot pedal area 11 and will be difficult to flow out of the hull 1 from the open compartment 15; and the moving hull 1 will have relative displacement with the water, and the water flow will generate a thrust on the counterweight 72 and the swing plate 71, causing the counterweight 72 to rotate inward toward the swing groove 19, and the swing plate 71 to rotate synchronously. The swing plate 71 drives the eccentric plate 73 to rotate, so that the eccentric plate 73 drives the lifting frame 74 to drive the sliding rack 43 to move upward, and then the sliding rack 43 separates from the rotating column gear 531.

[0081] When too much water remains in the foot pedal area 11, it is necessary to drain the water from the foot pedal area 11. At this time, the feet separate, the two foot pedal halves 211 move outward, and the pedal connecting rod 22 drives the drive slide rod 32 to move outward synchronously. The drive slide rod 32 no longer restricts the longitudinal movement of the synchronous plug 33.

[0082] As the slide block 31 moves on the hull 1, the synchronous insert block 33 will move along the lifting wall 413 and insert into the slot 412. Then the slide block 31 continues to move, driving the transmission belt 41 to reciprocate. The piston push plate 414 drives the piston drive plate 621 to reciprocate, causing the piston body 62 to reciprocate inside the pump housing 61. The pump body 6 draws water from the foot pedal area 11 into the pump housing 61 through the drain pipe 17 and the inlet check valve 611, and discharges it to the outside of the hull 1 through the outlet check valve 612.

[0083] Once the water in the foot pedal area 11 is completely drained, bring your feet together. The two foot pedal halves 211 move to their closest extreme positions, driving the slide bar 32 to keep the synchronizing block 33 in the longitudinal slide groove 311, and the synchronizing block 33 separates from the transmission belt 41.

[0084] After the activity, the hull 1 stops moving, and the counterweight 72 hangs down under its own weight, causing the eccentric plate 73 to drive the lifting frame 74 to move downward, and the sliding rack 43 meshes with the rotary gear 531.

[0085] With the feet separated, the two foot pedal halves 211 move to their extreme positions far apart from each other, and the drive slide bar 32 no longer restricts the longitudinal movement of the synchronous plug 33; the slide block 31 moves so that the synchronous plug 33 is inserted into the slot 412, and then the slide block 31 moves in the opposite direction so that the sliding rack 43 drives the sealing plate 54 to rotate in the opposite direction, and the corrugated sleeve 51 retracts to its extreme position and returns to its initial state.
