Description

Technical Field

[0001] The invention relates to the technical field of deep-water towing pool experiments, in particular to a deep-water towing pool movable dock with adjustable intermediate distance. Background Art

[0002] The deep-water towing pool is the core equipment and prerequisite for conducting rapid tests on ship models. Its dock is usually a reinforced concrete structure fixed on both sides of the pool. It is mainly used for ship model ballasting and waterline observation operations: personnel will hoist the ballast onto the ship model in the center of the pool in the dock, observe the waterline and level it. Since this type of dock is a fixed form, the width of the passage between the two docks is fixed, which is suitable for the ballasting and passage of conventional-sized ship models. For ship models with larger widths such as engineering ships and ground-effect wing-craft, it is often impossible to ballast in the dock area. For models that are too small, it is difficult to get close to observe, and the operation is also very inconvenient.

[0003] The existing docks in deep-water towing pools are mostly fixed in form. Ship models with a larger width cannot be ballasted in the dock area, and ship models that are too small are difficult to observe at close range and are not convenient for operation.

[0004] For this reason, we propose a deep-water towing pool movable dock with adjustable middle distance. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a deep-water towing pool mobile dock with adjustable intermediate distance. The distance between the mobile platforms can be continuously adjusted to move close to the ship model. In addition to placing ballast, observing and adjusting the waterline, it can also be used with a small amount of tooling to install and replace propellers, instruments and equipment. Moving the platforms to both sides of the pool also ensures the width of the test water area and reduces the impact on water flow and testing.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A deep-water towing pool movable dock with adjustable intermediate distance, comprising:

[0008] Two mobile platforms are respectively arranged on both sides of the pool wall;

[0009] The traction components are arranged on both sides of the pool and are used to drive the mobile platform to move;

[0010] A movable channel is arranged above the movable platform, and the movable channel can be pushed along the length direction of the pool;

[0011] The bottom of the mobile platform is provided with solid ballast and running wheels, the bottom of the pool is provided with tracks, and the running wheels are arranged in the tracks and can move along the tracks;

[0012] The traction assembly includes a winch, a pulley, and a steel wire rope. Each mobile platform is provided with a winch at both ends of the length direction of the pool. A single layer of steel wire rope is wound around the winch drum. Pulleys are provided at the top and bottom of the pool wall. The steel wire rope passes through a group of pulleys. The two ends of the steel wire rope are fixedly connected to the pulling points on both sides of the mobile platform.

[0013] It is further characterized by:

[0014] The movable passage includes an upper aisle and a lower aisle. The upper aisle connects the two sides of the pool to facilitate people to move from one side of the pool to the other side. The lower aisle is used for people to move up and down the platform. The upper aisle and the lower aisle are connected by an inclined ladder.

[0015] The water pool is also provided with an electric control component, which includes a control button, a contactor, a limit switch, a brake limit protection device, and is equipped with an operation and fault alarm indicator light and a buzzer.

[0016] The box body of the mobile platform is provided with a personnel operation area and a ship model ballast stacking area, and the upper edge of the box body of the mobile platform is higher than the water surface of the pool.

[0017] The track comprises a bottom track and a side track. The side track is arranged on the bottom track. The side track is L-shaped. The bottom track and the side track cooperate to restrict the running wheels to prevent the running wheels from twisting and deflecting.

[0018] The running wheel is provided with a guide wheel, and the guide wheel cooperates with the side track for guiding.

[0019] The track is provided with four sections, which are laid on both sides of the bottom of the pool respectively, and the two sections of the track on each side are arranged opposite to each other in a "┏┒" shape.

[0020] The beneficial effects of the present invention are as follows:

[0021] The invention has a compact and reasonable structure and is easy to operate. The mobile platform has a light structure, a lower center of gravity than the center of buoyancy, and a slow moving speed. The wheels move in the track to limit twisting and deviation, ensuring smooth and reliable operation. The distance between the mobile platforms can be continuously adjusted to move close to the ship model. In addition to placing ballast, observing and adjusting the waterline, a small amount of tooling can also be used to install and replace propellers, instruments and equipment. Moving the mobile platforms to both sides of the pool also ensures the width of the test water area and reduces the impact on the water flow and the test.

[0022] At the same time, the present invention also has the following advantages:

[0023] (1) The mobile platform can be processed and assembled separately, which is simple to implement. It is helpful to reduce the total weight and reduce the resistance of the mobile platform moving in the water. Solid ballast is set at the bottom of the mobile platform so that the overall gravity is greater than the buoyancy and the center of gravity is lower than the center of buoyancy to ensure stable bottoming. The mobile platform has good strength and rigidity and can withstand the static pressure of the pool and the impact of waves. The box on the top of the mobile platform has a personnel operation area, a ship model ballast stacking area, and an inclined ladder for people to go up and down. The box on the top of the mobile platform is higher than the water surface as a whole. Eaves are set on the three sides of the upper end of the box on the top of the mobile platform, and no eaves are set on the side close to the pool wall. It can provide personnel or ballast for a short stay and prevent waves from rushing into the cabin. Tires can be set outside the eaves to prevent collisions and protect the model.

[0033] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0034] like Figure 1-8As shown, a deep-water towing pool movable dock with adjustable intermediate distance includes two mobile platforms 1, which are arranged on both sides of the pool wall, respectively. The box on the top of the mobile platform 1 is a coverless cabin structure, and the mobile platform 1 is an assembled truss structure under the coverless cabin structure. The bottom of the mobile platform 1 is provided with a solid ballast 2. The bottom of the mobile platform 1 is provided with a running wheel 3.

[0035] In one embodiment, the solid ballast 2 is cast heavy aggregate concrete.

[0036] The traction assembly 6 includes a winch 601, a pulley 604, and a steel wire rope 603. Each mobile platform 1 is provided with a winch 601 at both ends of the length direction of the pool. A single layer of steel wire rope 603 is wound on the drum 602 of the winch 601. Pulleys 604 are provided at the top and bottom of the pool wall. The steel wire rope 603 passes through a group of pulleys 604. Both ends of the steel wire rope 603 are respectively fixedly connected to the pulling points on both sides of the mobile platform 1. The winch 601 drives the drum 602 to pull the steel wire rope 603 in forward and reverse directions to pull the pulling point of the mobile platform 1 to drive the walking wheel 3 to move, so that the mobile platform 1 can move horizontally along the pool, and the distance between it and the ship model can be adjusted.

[0037] The pulling points on both sides of the mobile platform 1 are arranged up and down and staggered. A steel wire rope 603 passes through the drum 602 of the winch 601, and then passes through a set of pulleys 604. One end of the steel wire rope 603 is connected to the pulling point on one side of the mobile platform 1, and the other end of the steel wire rope 603 is connected to the pulling point on the other side of the mobile platform 1.

[0038] In the working state, the mobile platform 1 can be moved to the center of the pool, and the moving position can be adjusted independently and continuously. In the non-working state, the mobile platform 1 can be moved to both sides of the pool for parking.

[0039] The box body of the mobile platform 1 is provided with a personnel operation area and a ship model ballast stacking area, and the upper edge of the box body of the mobile platform 1 is higher than the water surface of the pool.

[0040] A track 4 is provided at the bottom of the pool, and the track 4 includes a bottom track 401 and a side track 402. The side track 402 is provided on the bottom track 401, and the side track 402 is L-shaped. The bottom track 401 and the side track 402 cooperate to restrict the running wheel 3 to prevent the running wheel 3 from twisting and deflecting. A guide wheel 301 is provided on the running wheel 3, and the guide wheel 301 cooperates with the side track 402 for guidance. The running wheel 3 is provided in the track 4 and can move along the track.

[0041] A moving channel 8 is provided above the moving platform 1, and the moving channel 8 can be pushed by hand. The moving channel 8 is a double-layer structure, and an inclined ladder is provided between the two layers of the moving channel 8, so that people can move between the two layers of the moving channel 8 and go down to the moving platform 1 from the moving channel 8.

[0042] The movable dock in this application is particularly suitable for ballasting, installing and testing ship models in deep-water towing pools: the bottom-type mobile platform 1 is specially designed, the structure weight of the mobile platform 1 is light, the center of gravity of the mobile platform 1 is lower than the center of buoyancy, the moving speed is slow, and the running wheel 3 moves in the track 4 to limit its torsion and deviation, ensuring smooth and reliable operation. The distance between the mobile platforms 1 can be continuously adjusted to move close to the ship model. In addition to placing ballast, observing and adjusting the waterline, it can also be equipped with a few tooling to install and replace propellers, instruments and equipment. Moving the mobile platform 1 to both sides of the pool also ensures the width of the test water area and reduces the impact on the water flow and the test.

[0043] The mobile platform 1 can be processed and assembled separately, and the implementation is simple; it is conducive to reducing the total weight and reducing the resistance of the mobile platform 1 moving in the water; a solid ballast 2 is arranged at the bottom of the mobile platform 1 so that the overall gravity is greater than the buoyancy, and the center of gravity is lower than the center of buoyancy, ensuring stable bottoming. The mobile platform 1 has good strength and stiffness, and can withstand the static pressure of the pool and the impact of waves. The box on the top of the mobile platform 1 has a personnel operation area, a ship model ballast stacking area, and an inclined ladder for people to go up and down. The box on the top of the mobile platform 1 is higher than the water surface as a whole. The top three sides of the box on the top of the mobile platform 1 are provided with eaves, and no eaves are arranged on the side close to the pool wall, which can provide personnel or ballast for a short stay, and can also prevent waves from rushing into the cabin. Tires can be arranged outside the eaves to prevent collisions and protect the model.

[0044] The pulling points are arranged at the front and rear ends along the length direction of the mobile platform 1, and the pulling points are close to and slightly lower than the center of gravity of the platform along the height direction to reduce the deflection and tipping of the platform. The running wheels 3 are arranged symmetrically along the length direction of the mobile platform 1, and the running wheels 3 close to the longitudinal center line of the pool along the width direction are arranged on the outside of the mobile platform 1, with a larger wheelbase, which helps to maintain smooth movement.

[0045] There is no need to lay the track 4 near the center of the pool. Four sections of track 4 are set on both sides of the bottom of the pool. The two sections of track 4 on each side are arranged opposite to each other in a "┏┒" shape. A groove will be formed between the bottom track 401 and the side track 402, which will limit the running wheel 3 in the groove of the track 4 to prevent the mobile platform 1 from floating up and tipping over. In order to avoid eccentricity, two running wheels 3 are set on a wheel frame. The two running wheels 3 are arranged symmetrically, one in the groove of the track 4 and the other directly falls on the track surface of the track 4, so that the running wheel 3 and the wheel axle are more evenly stressed and have better stability. The wheel frame is also provided with a horizontal guide wheel to play a mechanical deviation correction role. Vehicle stops 5 are set at both ends of each section of track 4. The vehicle stops 5 are installed with buffer rubber pads to limit the mobile platform 1 and prevent collision.

[0046] The mobile platform 1 adopts the traction method of winch 601 and wire rope 603. Each mobile platform 1 is individually pulled by a set of traction components 6. By controlling the reel 602 to pull the wire rope 603 forward and reversely to pull the lower pulling point of the mobile platform 1, the mobile platform 1 can be moved horizontally along the pool to adjust the distance from the ship model.

[0047] A moving channel 8 is provided above the moving platform 1, and the moving channel 8 can be pushed by hand and moved arbitrarily along the length direction of the pool. The moving channel 8 includes two layers of aisles, the upper aisle connects the two sides of the pool, which is convenient for people to move from one side of the pool to the other side, and the lower aisle is for people to move the platform 1 up and down. The moving channel 8 is equipped with a simple rail clamp for locking and preventing sliding when stopped.

[0048] The pool is also provided with an electric control assembly 7, which includes a control button, a contactor, a limit switch, a brake limit protection device, etc., and is equipped with an operation and fault alarm indicator light and a buzzer. A cam limit switch is provided on the drum 602 of the winch 601, and a stop point is provided in each forward and reverse directions to provide safety limit protection for the left and right end travels of the mobile platform 1. The mobile platform 1 adopts a conventional contactor control method. Each side of the mobile platform 1 is driven by two winches 601, which are driven by an electric motor and have linkage, single action, stop, safety protection and emergency stop modes. In the linkage mode, the two winches 601 of each mobile platform 1 move simultaneously, forward or backward. The single action mode is mainly used for inching fine adjustment of the wire rope 603 when the mobile platform 1 is deflected. The safety protection mode performs safety braking when the mobile platform 1 encounters a limit.

[0049] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
