Detailed description of the invention
In order to summary of the invention of the present utility model, feature and function can be understood further, hereby enumerate following examples, and coordinate accompanying drawing to be described in detail as follows:
Illustrate in Fig. 1 with Fig. 2 that a kind of ship load detecting device comprises the vertical water level permeator 1 being placed in boats and ships center, the upper end of coolant inlet pipe 2 is connected with water level permeator 1, below the external unloaded water surface of boats and ships is stretched into as water inlet 15 in the lower end of coolant inlet pipe 2, floating drum 3 is placed in water level permeator 1, can fluctuate according to the water level in water level permeator 1, by displacement and the deadweight of vessel of its real-time reaction boats and ships, chain 4 is engaged in sprocket gear 5, sprocket gear 5 engages with quadrant gear 8, quadrant gear 8 suspends and is provided with gauge panel 6, one end of chain 4 connects floating drum 3, the other end connects weight 9, weight 9 is placed within conduit 10, can up and down freely not by external interference, pointer 11 is fixed on the center of circle of quadrant gear 8, the keying of corresponding indicator lamp and annunciator 13 in control circuit loop, one group of contact 12 7.
In load-carrying testing process, when deadweight of vessel increases, water level in water level permeator 1 rises, floating drum 3 also rises thereupon, chain 4 makes sprocket gear 5 rotate counterclockwise under the Action of Gravity Field of weight 9, drive quadrant gear 8 and pointer 11 to rotate clockwise, pointer 11 indicates the relevant position to gauge panel 6, can show the real-time load amount of boats and ships simultaneously.The heavy 3-4KG of the comparable weight 9 of floating drum 3.Meanwhile, connect corresponding contact in 12, corresponding indicator lamp and sounding alarm 13 are also switched on.
When deadweight of vessel reduces, water level decreasing in water level permeator 1, floating drum 3 also declines thereupon, chain 4 makes sprocket gear 5 rotate clockwise under the Action of Gravity Field of floating drum 3, and drive quadrant gear 8 and pointer 11 to rotate counterclockwise, pointer 11 indicates the relevant position to gauge panel 6 simultaneously, the real-time load amount of boats and ships can be shown, meanwhile, connect corresponding contact in 12, corresponding indicator lamp and generation annunciator 13 are also switched on.
Under floating drum stabilized conditions, the weight relationships between floating drum and weight meets following equation: the gravity of the buoyancy=weight of the gravity-floating drum of floating drum.The motion principle of this device of labor is as follows:
Initial condition, ship load is zero, and draft is constant, and the immersed water level of floating drum is constant, is subject to constant buoyancy, the buoyancy of the deadweight+floating drum of the deadweight=weight of floating drum, the buoyancy F of floating drum
floating=ρ

rowbe the volume that floating drum arranges liquid, S is the floor space of floating drum, h
leachingit is the degree of depth that floating drum immerses liquid level in water level permeator 1.
At first, the loading displaying device of ship load detecting device is in zero-bit time unloaded, along with load-carrying increases, draft is deepened, moment, the immersed water level of floating drum was deepened, and buoyancy increases, under gravity, the trend of floating drum and chain oriented weight direction motion, when the buoyancy increased enough overcomes the static friction force F between chain 4 and sprocket gear 5
rubtime, chain is to the motion of weight direction, and the immersed water level of floating drum decreases, and the buoyancy of floating drum reduces, until reach new balance, now the immersed water level of floating drum returns constant, but pointer turns to corresponding display position along with the motion of chain.
When unloading ships, draft shoals instantaneously, and the immersed water level of floating drum shoals, and buoyancy reduces, and under gravity, the trend of floating drum and chain oriented floating drum direction motion, when the buoyancy reduced enough overcomes the static friction force F between chain 4 and sprocket gear 5
rubtime, chain is to the motion of floating drum direction, and the immersed water level of floating drum increases thereupon, and the buoyancy of floating drum increases, until reach new balance, now the immersed water level of floating drum returns constant, but pointer is turned back to corresponding display position along with the motion of chain.During ship in ballast, pointer returns zero-bit.
As the above analysis, the weight of floating drum must be greater than the weight of weight, the change in displacement numerical value of floating drum 3 in water level permeator 1 can change into the change that pointer 11 indicates position to gauge panel 6, can reflect the change of the real-time load amount of boats and ships, and the zero-bit of this device can return to zero when ship in ballast.
Adopt the design of the formula of full machinery that liquid level data can be made to be converted into load-carrying data lossless to lose, thus reflect load-carrying data more accurately.Wherein, good scheme is fan-shaped by design of gears, adopts the design of fully mechanical that liquid level data can be made to be converted into load-carrying data lossless and lose, thus reflect load-carrying data more accurately, better effects if, and not fragile, and weather resisting property improves.
Light and sound prompting staff can be adopted when load-carrying excess, the problem that load-carrying excess is brought can be processed in time.
The water inlet of condensate tank of dehumidifier is arranged at the center of bottom of ship, the impact of stormy waves can be avoided, thus reduce the error of level sensing, thus the ship load value drawn is also more accurate.
