Description

Technical Field

[0001] This utility model relates to the field of buoyancy power machinery technology, and more specifically, to a pontoon structure. Background Technology

[0002] Chinese invention patent "A Drainage-Mounted Buoyancy-Type Energy Conversion Device and Method" (Publication No.: CN108869162A) describes an energy conversion device comprising a water storage tank, a rotating wheel, and floats. Each float has a buoyancy cavity, and each float is connected to an inlet / outlet assembly to allow water to enter and exit the buoyancy cavity. Through the inlet and outlet of the buoyancy cavity, the energy conversion device ensures that the resultant force of the float's weight and buoyancy acts downwards on the descending side of the rotating wheel and upwards on the ascending side, driving the rotating wheel to rotate and generating kinetic energy. This converts the work done by the float's weight and buoyancy into other forms of energy.

[0003] The float structure of this energy conversion device involves the actuator releasing the impermeable cloth to stop the float when it needs to sink. Water enters the float cavity, and the impermeable cloth also enters and adheres to the cavity wall, almost completely purging the air inside the float cavity. When the float needs to switch from a sinking to a floating state, the actuator pulls the impermeable cloth out of the float cavity to expel the water and draw in air, increasing the float's buoyancy and causing it to rise. However, during the drainage initiation, the base connecting the impermeable cloth and the actuator is pressed against the bottom of the float cavity. Besides being pressed tightly against the bottom of the float cavity by water pressure, the base is also subject to a vacuum-like adsorption force between the float cavity and the impermeable cloth. Therefore, pulling the base in this state requires a very large pulling force, placing high demands on the actuator's performance and necessitating the use of an expensive actuator, thus increasing the overall cost of the equipment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a float structure. This float structure can reduce the water pressure and vacuum adsorption force when starting drainage, reduce the pulling force required to pull the end cap, save equipment costs, and improve operational reliability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pontoon structure, characterized in that it includes a pontoon body with a cavity, a waterproof cloth cover, a head seat, and a pulling mechanism; the cavity wall of the pontoon body has an air inlet and outlet; one end of the waterproof cloth cover has a cover opening, which covers the opening of the cavity of the pontoon body; the other end of the waterproof cloth cover is connected to the head seat; the head seat is connected to the pulling mechanism to realize that the pulling mechanism pulls the head seat to move; when the head seat is in the state closest to the bottom wall of the cavity of the pontoon body, the bottom surface of the head seat and the bottom wall of the cavity of the pontoon body are in direct contact with each other, or indirect contact through the waterproof cloth cover; the bottom surface of the head seat and / or the bottom wall of the cavity of the pontoon body form an outwardly protruding part.

[0006] In this invention, the pulling mechanism is in a released brake state. Under water pressure, the impermeable cloth cover is drawn into the buoy body cavity, and water also enters the buoy body cavity. The air in the impermeable cloth cover and the buoy body cavity is discharged from the air inlet and outlet, and the impermeable cloth cover is close to the wall of the buoy body cavity. When the impermeable cloth cover enters to the deepest part of the buoy body cavity, that is, when the end cap directly or indirectly contacts the bottom wall of the buoy body cavity, the air in the impermeable cloth cover and the buoy body cavity is almost completely discharged, and the space between the impermeable cloth cover and the buoy body cavity is close to a vacuum state. The bottom surface of the end cap and / or the bottom wall of the buoy body cavity form a protrusion, which allows the impermeable cloth cover to partially enter the gap below the end cap and around the protrusion under water pressure, so that the bottom surface of the end cap does not completely adhere to the bottom wall of the buoy body cavity. In this state, when the pulling mechanism is activated, the bottom surface of the end cap is not completely attached to the bottom wall of the float body cavity, which can effectively reduce the water pressure force and the vacuum adsorption force on the end cap. Therefore, compared with the original float, this utility model can use a smaller pulling force to move the waterproof cloth cover out of the float body cavity, reducing the pulling force requirement of the pulling mechanism, saving equipment costs, and improving the reliability of operation.

[0007] Preferably, the end cap is provided with an end cap cavity for increasing buoyancy; this can increase the buoyancy of the end cap, so that when the float body is placed horizontally in the water, the end cap can have a certain buoyancy in the water and will not sink to the area of ​​another float body below.

[0008] Preferably, the protrusion refers to a protruding arc surface.

[0009] Preferably, the raised arc surface is located on the bottom surface of the end cap; the bottom wall of the pontoon body cavity is flat; and the air inlet and outlet are located in the middle of the bottom wall of the pontoon body cavity. This arrangement can make full use of the pontoon structure space.

[0010] Preferably, the top of the end cap has an inwardly recessed cavity; the recessed cavity forms a mounting platform; and the pulling mechanism is connected to the mounting platform.

[0011] Preferably, the pulling mechanism includes a fixed pulley block, a movable pulley block, a rope, a winch drum, and a rotary drive device for driving the winch drum to rotate; the movable pulley block is mounted on the end cap; both ends of the rope are fixed to the winch drum, and the rope is wound around the winch drum, the fixed pulley block, and the movable pulley block, so that during the rotation of the winch drum, the rope can be wound up to shorten the rope length between the fixed pulley block and the movable pulley block, or the rope can be released to increase the rope length between the fixed pulley block and the movable pulley block.

[0012] The rotary drive device operates in three states: stopped, brake released, and running. When drainage is required, the rotary drive device operates, rotating the winch drum to wind up the rope, shortening the rope length between the fixed and movable pulley blocks. This pulls the end cap seat out of the float's main body cavity, thus extending the waterproof cloth cover and allowing the float to drain water and take in air. When the drainage volume reaches a set value, or the rope is wound to a set length, the rotary drive device stops. When water intake is required, the rotary drive device releases the brake, and the water pressure draws the waterproof cloth cover into the float's main body cavity. The end cap seat then pulls the movable pulley block, increasing the rope length between the fixed and movable pulley blocks, allowing the winch drum to release the rope.

[0013] Preferably, the rotary drive device refers to an electric motor.

[0014] Preferably, the length of the impermeable cloth cover is greater than or equal to the depth of the buoy body cavity; this allows the impermeable cloth cover to fit snugly inside the buoy body cavity, maximizing the removal of air from the buoy body and increasing the buoyancy variation of the buoy body.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. By adopting this utility model, when drainage is started, the water pressure force and vacuum adsorption force can be effectively reduced; the pulling force requirement of the pulling mechanism is reduced, equipment costs are saved, and the reliability of operation is improved;

[0017] 2. In this utility model, the end cap has good buoyancy, so that when the float body is placed horizontally in the water, the end cap can have a certain buoyancy in the water and will not sink to the area of ​​another float body below. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] This embodiment describes a pontoon structure, such as... Figures 1 to 4 As shown, the system includes a float body 1 with a cylindrical cavity, a waterproof cloth cover 2, a head seat 3, and a pulling mechanism 4. The cavity wall has inlet and outlet ports; one end of the waterproof cloth cover 2 has a cover opening that covers the opening of the cylinder cavity of the float body 1; the other end of the waterproof cloth cover 2 is connected to the head seat 3. The length of the waterproof cloth cover 2 is greater than or equal to the depth of the cylinder cavity of the float body 1; this allows the waterproof cloth cover 2 to fit snugly inside the cylinder cavity of the float body 1, maximizing the removal of air from the inside of the float body 1 and increasing the buoyancy variation of the float body 1.

[0026] The end cap 3 is connected to the pulling mechanism 4 so that the pulling mechanism 4 can pull the end cap 3 to move. When the end cap 3 is in the state closest to the bottom wall of the buoy body 1, the bottom surface of the end cap 3 and the bottom wall of the buoy body 1 are in direct contact with each other, or indirect contact through the waterproof cloth cover 2.

[0027] The head seat 3 is provided with a head seat cavity 32 for increasing buoyancy; this can increase the buoyancy of the head seat 3 so that when the float body is placed horizontally in the water, the head seat 3 can have a certain buoyancy in the water and will not sink too much.

[0028] The bottom surface of the head seat 3 and / or the bottom wall of the buoy body 1 cavity form an outwardly protruding portion. Specifically, the protruding portion refers to the protruding arc surface 31. In this embodiment, the protruding arc surface 31 is located on the bottom surface of the head seat 3; the bottom wall of the cavity is flat; the inlet and outlet are located in the middle of the bottom wall of the cavity; this arrangement can make full use of the space of the buoy structure. In practical applications, the protruding arc surface can also be set on the bottom wall of the buoy body cavity, while the bottom surface of the head seat is flat; or both the bottom wall of the buoy body cavity and the bottom surface of the head seat are protruding arc surfaces.

[0029] In this invention, the pulling mechanism 4 is in a released brake state. Under water pressure, the impermeable cloth cover 2 is drawn into the cavity of the float body 1. At the same time, water also enters the cavity of the float body 1. The air in the cavity of the impermeable cloth cover 2 and the float body 1 is discharged from the air inlet and outlet. The impermeable cloth cover 2 is close to the wall of the cavity of the float body 1. When the impermeable cloth cover 2 enters to the deepest part of the cavity of the float body 1, that is, when the end cap 3 directly or indirectly contacts the bottom wall of the cavity of the float body 1, the air in the cavity of the impermeable cloth cover 2 and the float body 1 is almost completely discharged. The space between the impermeable cloth cover 2 and the cavity of the float body 1 is close to a vacuum state. The bottom surface of the end cap 3 and / or the bottom wall of the cavity of the float body 1 form a protrusion, which allows the impermeable cloth cover 2 to partially enter the gap below the end cap 3 and around the protrusion under water pressure, so that the bottom surface of the end cap 3 does not completely adhere to the bottom wall of the cavity of the float body 1. In this state, when the pulling mechanism 4 is activated, since the bottom surface of the end cap 3 is not completely attached to the bottom wall of the pontoon body 1, the water pressure force and the vacuum adsorption force on the end cap 3 can be effectively reduced. Therefore, compared with the original pontoon, this utility model can use a smaller pulling force to move the impermeable cloth cover 2 out of the pontoon body 1, reducing the pulling force requirement of the pulling mechanism 4, saving equipment costs, and improving the reliability of operation.

[0030] The top of the end cap 3 is provided with an inwardly recessed cavity 33; the recessed cavity 33 forms a mounting platform; the pulling mechanism 4 is connected to the mounting platform.

[0031] The pulling mechanism 4 includes a fixed pulley block 42, a movable pulley block 44, a rope 43, a winch drum 41, and a rotary drive device for driving the winch drum 41 to rotate. The movable pulley block 44 is mounted on the end cap 3. The two ends of the rope 43 are respectively fixed to the winch drum 41, and the rope 43 is wound around the winch drum 41, the fixed pulley block 42, and the movable pulley block 44. This allows the winch drum 41 to rotate, either by winding up the rope 43 to shorten the length of the rope 43 between the fixed pulley block 42 and the movable pulley block 44, or by releasing the rope 43 to increase the length of the rope 43 between the fixed pulley block 42 and the movable pulley block 44.

[0032] The rotary drive device operates in three states: stopped, brake released, and running. When drainage is required, the rotary drive device operates, rotating the winch drum 41 to wind up the rope 43, shortening the length of the rope 43 between the fixed pulley block 42 and the movable pulley block 44. This pulls the end cap 3 out of the cavity of the float body 1, thereby pulling out the waterproof cloth cover 2, allowing the float body 1 to drain water and take in air. When the drainage volume reaches a set value, or the rope is wound to a set length, the rotary drive device stops. When water needs to be introduced, the rotary drive device releases the brake, and the water pressure brings the waterproof cloth cover 2 into the cavity of the float body 1. The end cap 3 then pulls the movable pulley block 44, increasing the length of the rope 43 between the fixed pulley block 42 and the movable pulley block 44, and the winch drum 41 releases the rope 43.

[0033] The winch and rotary drive can both utilize existing technologies. The rotary drive can be an electric motor.

[0034] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
