[0002] With the continuous development of industry and the improvement of people's quality of life, the demand for water vehicles is also gradually increasing. When driving a water vehicle, in addition to driving on the deep river surface, it is sometimes necessary to drive to some shallow areas. However, when a water vehicle encounters a shallow area, the pedal-driven propeller may touch the bottom. The current solution for water vehicles is to lay the entire propeller flat in the cabin to avoid touching the bottom, but this is not convenient and requires a larger opening space to be set in the hull, which may also affect the stability and buoyancy of the vessel. Therefore, it is particularly important to find a more effective way to recover the propeller in order to improve the seaworthiness, stability and convenience of the vessel.

[0003] The existing problem is that it is not convenient to recycle propellers in existing water vehicles, as it not only requires a larger opening space to be set in the hull, but may also affect the stability of the vessel. Utility Model Content

[0004] The utility model solves the technical problem that it is not convenient to recover the propeller of existing water transportation vehicles, which not only requires a large opening space to be set in the hull, but may also affect the stability of the ship. By making the lifting member move relative to the driving base in the length direction of the lifting member, the propeller can be quickly recovered and the opening space of the hull can be effectively reduced, thereby achieving the technical effect of increasing the stability and convenience of the ship.

[0005] In order to solve the above problems, the utility model provides a pedal drive device, comprising: a driving base, the driving base is installed at the opening of the hull; a pedal and a lifting member, the pedal is connected to one end of the lifting member, the lifting member passes through the driving base and is partially placed on the bottom of the ship; a spiral device, the spiral device is connected to the other end of the lifting member, and the spiral device is placed on the bottom of the ship; wherein the pedal can drive the spiral device to rotate; when the lifting member moves relative to the driving base in the length direction of the lifting member, it will drive the spiral device to move in a direction close to or away from the driving base.

[0006] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by installing the lifting member through the driving base and making it move relative to the driving base in the length direction of the lifting member, compared with the large opening of the traditional hull, this innovation effectively reduces the opening size of the hull, thereby significantly improving the stability of the hull. In addition, the spiral device moves in the direction of approaching the driving base as the lifting member moves, realizing efficient storage of the spiral device. This design not only optimizes the hull structure technically, but also brings higher safety and stability to ship operation, providing more reliable protection for ship driving.

[0007] In an example of the present utility model, the pedal drive device further comprises a limit device, which is mounted on the drive base, wherein when the limit device is in a locked state, the limit device will limit the movement of the lifting member relative to the drive base.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by installing a limit device on the driving base, the position of the lifting member can be locked by the limit device after it is moved, thereby effectively maintaining the stable position of the lifting member. This technological innovation not only ensures the precise positioning of the lifting member during movement, but also improves the reliability and stability of the system.

It not only ensures the close connection between the limit plate and the lifting member, but also improves the stability and accuracy of the system, providing an important guarantee for the reliable operation of the device.

[0011] In one example of the utility model, the driving base includes: a fixed base; a movable base, the movable base is installed on the fixed base, and the movable base can move relative to the fixed base; wherein the lifting member is installed on the movable base, and when the movable base moves relative to the fixed base, the lifting member will move with the movable base.

[0013] In one example of the utility model, the pedal drive device also includes a blocking member, which includes: a knob, which is installed on a side of the movable seat close to the pedal member; a rotating disk, which is installed on a side of the movable seat close to the spiral device, and the rotating disk passes through the movable seat and is connected to the knob; at least one blocking bar, and at least one blocking bar is installed on the rotating disk; wherein, rotating the knob will drive the rotating disk to rotate, and when the blocking bar moves in a direction close to the fixed seat, the blocking member will limit the movement of the movable seat relative to the fixed seat; when the blocking bar moves in a direction away from the fixed seat, the blocking member will release the restriction on the movable seat.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: installing the knob on the side of the movable seat close to the pedal can make the user's operation more convenient. And by rotating the rotating disk to drive the blocking bar, the activity of the blocking bar is simplified, and the operation efficiency is improved. The blocking member effectively controls the activity between the movable seat and the fixed seat, which is convenient for the installation and storage of the spiral device. This design not only increases the convenience of operation, but also optimizes the functionality of the system, making the operation of the ship equipment smoother and more efficient.

[0015] In one example of the utility model, the driving base also includes at least one clamping groove and a clamping boss, and the clamping groove and the clamping boss are arranged on a side of the fixed base close to the spiral device; wherein, when the blocking member is in a blocking state, the blocking bar will be inserted into the clamping groove, and the rotating disk will be clamped with the clamping boss.

In addition, a clamping boss is provided on the fixed seat corresponding to the rotating disk, and when the blocking member is in the blocking state, the cooperation between the clamping boss and the rotating disk can enhance the stability of the blocking member.

[0017] In one example of the utility model, the pedal drive device also includes a positioning member, which is installed through the fixed seat; the driving base also includes a plurality of positioning holes, which are installed on the movable seat and arranged corresponding to the positioning member; wherein, when the positioning member is inserted into the positioning holes at different positions, the angle between the movable seat and the fixed seat is different.

[0018] Compared with the prior art, the technical effect achieved by adopting this technical solution is: a plurality of positioning holes at different positions are set on the movable seat, and by adjusting the positioning pieces on the fixed seat to insert into different positioning holes, the movable seat and the fixed seat can maintain different angles. This design can effectively fix the angle between the movable seat and the fixed seat when the spiral device is stored, ensuring the stability and reliability of the system during operation, and effectively improving the flexibility and accuracy of the operation.

[0019] In one example of the utility model, the positioning member includes: a positioning column, which passes through the fixed seat and can be inserted into the positioning hole; a positioning head, which is connected to the positioning column and is placed on a side of the fixed seat away from the movable seat; a spring member, which is sleeved on the positioning column and is placed on a side of the fixed seat close to the movable seat; wherein, pulling the positioning head can cause the positioning column to move in a direction away from the positioning hole; releasing the positioning head, the spring member can cause the positioning column to move in a direction close to the positioning hole.

[0020] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by inserting the positioning column into the positioning hole, the movable seat is effectively fixed. The positioning column is connected by a positioning head, and is arranged on the side of the fixed seat away from the movable seat, so that the user can easily pull the positioning head to release the fixation of the movable seat. In addition, the spring member is sleeved on the positioning column. When the positioning column is pulled away from the positioning hole, the restoring force of the spring member will automatically drive the positioning column to reinsert into the positioning hole, achieving a fast and reliable fixing effect.

[0022] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the fan blade cover and the fan blade hole, the effective management of the fan blade during the storage process of the spiral device is successfully achieved. When the fan blade cover is closed, it can effectively prevent the water splashing from the bottom of the ship into the ship's hold; when the spiral device is recovered, the fan blade can push the fan blade cover open, and the fan blade can pass through the fan blade hole to achieve effective storage of the spiral device.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] See also Figures 1 to 7 The present embodiment provides a pedal drive device, comprising: a driving base 10, the driving base 10 is installed at the opening of the hull; a pedal 20 and a lifting member 30, the pedal 20 is connected to one end of the lifting member 30, the lifting member 30 passes through the driving base 10, and a part of it is placed on the bottom of the ship; a spiral device 40, the spiral device 40 is connected to the other end of the lifting member 30, and the spiral device 40 is placed on the bottom of the ship; wherein the pedal 20 can drive the spiral device 40 to rotate; when the lifting member 30 moves relative to the driving base 10 in the length direction of the lifting member 30, it will drive the spiral device 40 to move in the direction close to or away from the driving base 10.

[0036] Specifically, in this embodiment, the driving base 10 is installed at the opening of the hull, and the lifting member 30 passes through the driving base 10, and is partially inserted into the water through the opening of the hull. The pedal 20 is connected to the lifting member 30 and is placed on one side of the cabin, and the spiral device 40 is connected to the lifting member 30 and is placed on one side of the bottom of the boat. When the user drives the boat outdoors, by stepping on the pedal of the pedal 20, the fan blades of the spiral device 40 can be driven to rotate, providing power for the boat. Among them, the lifting member 30 and the driving base 10 are movably connected, and the spiral device 40 can be moved in the direction close to the driving base 10 by pulling the lifting member 30, so that the boat can travel in some shallow water areas.

[0037] Furthermore, the pedal drive device further includes a limit device 50 , which is mounted on the drive base 10 . When the limit device 50 is in a locked state, the limit device 50 will limit the movement of the lifting member 30 relative to the drive base 10 .

[0038] Specifically, the limiting device 50 is installed on the driving base 10, and the lifting member 30 and the driving base 10 are movably connected. Therefore, after adjusting the positional relationship between the lifting member 30 and the driving base 10, the positional relationship between the lifting member 30 and the driving base 10 can be kept fixed through the limiting device 50.

[0039] Furthermore, the limiting device 50 includes: a limiting plate 51; a limiting member 52, the limiting member 52 is installed on the driving base 10, and the limiting plate 51 is connected to the limiting member 52; wherein, when the limiting member 52 is rotated so that the limiting plate 51 is close to the lifting member 30, the limiting device 50 is in a locked state, and the limiting plate 51 will limit the movement of the lifting member 30 relative to the driving base 10.

[0040] Specifically, in the present embodiment, the limit plate 51 is installed on the side of the driving base 10 close to the lifting member 30, and the limit plate 52 passes through the driving base 10 and is fixed to the limit plate 51, wherein the limit plate 52 and the driving base 10 are spirally connected, and the limit plate 51 can be driven to be close to the lifting member 30 by rotating the limit plate 52. The friction between the limit plate 51 and the lifting member 30 can limit the lifting member 30 from sliding relative to the limit plate 51, thereby realizing the effective fixation of the lifting member 30 by the driving base 10.

[0041] Furthermore, the driving base 10 includes: a fixed base 11; a movable base 12, the movable base 12 is installed on the fixed base 11, and the movable base 12 can move relative to the fixed base 11; wherein, the lifting member 30 is installed on the movable base 12, and when the movable base 12 moves relative to the fixed base 11, the lifting member 30 will move with the movable base 12.

[0042] Specifically, the movable seat 12 is connected to the fixed seat 11 via a connecting shaft, and the movable seat 12 can rotate relative to the fixed seat 11 via a rotating shaft to form different angles. After the screw device 40 is pulled to release from the movable seat 12, the movable seat 12 is controlled to rotate relative to the fixed seat 11, and the screw device 40 can be flipped from the bottom of the ship to the cabin, completing the storage of the screw device 40.

[0043] Furthermore, the pedal drive device also includes a blocking member 60, which includes: a knob 61, which is installed on the side of the movable seat 12 close to the pedal member 20; a rotating disk 62, which is installed on the side of the movable seat 12 close to the spiral device 40, and the rotating disk 62 passes through the movable seat 12 and is connected to the knob 61; at least one blocking bar 63, and at least one blocking bar 63 is installed on the rotating disk 62; wherein, rotating the knob 61 will drive the rotating disk 62 to rotate, and when the blocking bar 63 moves in a direction close to the fixed seat 11, the blocking member 60 will limit the movement of the movable seat 12 relative to the fixed seat 11; when the blocking bar 63 moves in a direction away from the fixed seat 11, the restriction of the movable seat 12 by the blocking member 60 will be released.

[0044] Specifically, in this embodiment, the knob 61 is installed on the side of the movable seat 12 close to the pedal 20, which can facilitate the user to rotate the knob 61. When the knob 61 is rotated to the locking position, the rotating disk 62 drives the blocking bar 63 to move toward the fixed seat 11, thereby limiting the rotation of the movable seat 12 relative to the fixed seat 11. When the knob 61 is rotated to the unlocking position, the rotating disk 62 drives the blocking bar 63 to move toward the center of the rotating disk 62, thereby contacting the blocking bar 63 to limit the fixed seat 11.

[0045] Furthermore, the driving base 10 also includes at least one snap-fitting groove 13 and a snap-fitting boss 14, and the snap-fitting groove 13 and the snap-fitting boss 14 are arranged on the side of the fixed base 11 close to the spiral device 40; wherein, when the blocking member 60 is in a blocking state, the blocking bar 63 will be inserted into the snap-fitting groove 13, and the rotating disk 62 will be snap-fitted with the snap-fitting boss 14.

[0048] Specifically, a plurality of positioning holes 15 are provided at the position of the connecting shaft of the movable seat 12. When the movable seat 12 is rotated to form a corresponding angle between the movable seat 12 and the fixed seat 11, the positional relationship between the movable seat 12 and the fixed seat 11 can be fixed by inserting the positioning member 70 into the corresponding positioning hole 15.

[0049] Furthermore, the positioning member 70 includes: a positioning column 71, which passes through the fixed seat 11 and can be inserted into the positioning hole 15; a positioning head 72, which is connected to the positioning column 71 and is placed on the side of the fixed seat 11 away from the movable seat 12; a spring member 73, which is sleeved on the positioning column 71 and is placed on the side of the fixed seat 11 close to the movable seat 12; wherein, pulling the positioning head 72 can cause the positioning column 71 to move in a direction away from the positioning hole 15; releasing the positioning head 72, the spring member 73 can cause the positioning column 71 to move in a direction close to the positioning hole 15.

[0051] Furthermore, the driving base 10 also includes a blade hole 16 and a blade cover 17. The blade hole 16 is arranged on the movable seat 12, and the blade cover 17 is installed on the movable seat 12 corresponding to the blade hole 16. When the blade cover 17 is in an open state, the blade hole 16 will be exposed, and the blades of the spiral device 40 can pass through the movable seat 12 through the blade hole 16. When the blade cover 17 is in a closed state, the blade cover 17 will block the blade hole 16.

[0052] Specifically, the blade hole 16 is provided on the movable seat 12 corresponding to the blade of the spiral device 40, and the blade cover 17 is provided corresponding to the blade hole 16. When the spiral device 40 is recovered, the lifting member 30 is pulled to make the spiral device 40 approach the movable seat 12, and the blade of the spiral device 40 can pass through the blade hole 16 and push open the blade cover 17. When the blade cover 17 is closed, the blade hole 16 is covered, which can prevent water from the bottom of the ship from splashing into the cabin.

[0053] Furthermore, the pedal drive device also includes a locking device 80, which is installed on the pedal member 20; wherein the locking device 80 can lock the pedal member 20 when the length direction of the crank of the pedal member 20 is in the same direction as the length direction of the lifting member 30; and when the length direction of the crank is in the same direction as the length direction of the lifting member 30, the length direction of the fan blade of the spiral device 40 is also in the same direction as the length direction of the lifting member 30.

[0054] Specifically, in this embodiment, a locking device 80 is also installed on the pedal member 20, and the locking device 80 is provided with a locking column. The crank of the pedal member 20 is correspondingly provided with a locking hole. The locking column of the locking device 80 is inserted into the locking hole of the crank, and the pedal member 20 can be locked. Among them, when the crank and the lifting member 30 are in the same direction in length, the fan blades of the spiral device 40 are also in the same direction in length with the lifting member 30. By locking the pedal member 20 when the crank and the lifting member 30 are in the same direction in length, it can be ensured that the fan blades are in the same direction in length with the lifting member 30, thereby ensuring that when the spiral device 40 is stored, the fan blades can pass through the fan blade hole 16 normally.
