Description
Technical field
The utility model relates to U type tubular type inclining experiment device, is a kind of device of surveying the degree of tilt of ship.
Background technology
In the prior art, the degree of tilt of test ship has traditional pendulum method, and as shown in Figure 3, its principle is, swings because of the influence of inertia and wind-force produces in seawater according to boats and ships, is swung in oil groove by pendulum and embodies.Undertaken 1 by such step when making the test of pendulum method). according to " inclining experiment outline " requirement, cycloid 8 no pendulum one ends are suspended from the height of requirement, have pendulum one end then to put into oil groove.Oil groove to pack in advance certain altitude oil and ruler is fixed on the oil groove, pendulum requirement in oil groove can just be submerged.2). after pressing iron to move as requested, guarantee under the boats and ships pine cable state the corresponding data of opening entry at every turn.Adopt formula then and calculate angle: θ=arctg(△ L/ λ) (the adjacent twice reading mean value of △ L---poor, λ---cycloid length).There is following defective in this kind proving installation:
1). hang the pendulum pendulum length and require that sufficient length is arranged, if too short, then its pivot angle is less, and is bigger to the test findings influence, is difficult to guarantee accuracy.
2) if. oversize, then for spitkit, may be for hanging long clear height of hanging pendulum.
3). the material of cycloid.If too gentle, then can in the process of waving, may produce plastic yield, thereby test findings is brought certain influence.If material is a rigid material, in the process of swing, because the effect of self inertia can have influence on the accurate of reading.And then the result of influence test.
4). in the pendulum test, pendulum in addition may the front and back pendulum except vacillating now to the left, now to the right.Have influence on the accuracy and the accuracy of test figure.
The utility model content
The utility model technical issues that need to address provide U type tubular type inclining experiment device, this kind U type tubular type inclining experiment device, and long service life is saved cost, experiment accuracy height.
The utility model technical solution problem can be by taking following technical scheme:
U type tubular type inclining experiment device, it is characterized in that: comprise container, the U type pipe that to adorn liquid, container is provided with the opening that is in communication with the outside, one end of U type pipe connects container, the other end of U type pipe is measured end, measured end is provided with altitude scale or places the measurer place that can measure height, and container is communicated with U type pipe.
The utility model technical solution problem can also further be taked following innovative approach:
Its that end that connects container of U type pipe is connected with container in the bottom of container.
Described container is by bracket supports.
Its that end that connects container of U type pipe is connected with container by stop valve.
Described measured end is vertically, and described can tolerance measurer highly be ruler.
Described measured end places a vertical column of angles place, invests on the column of angles.
The utlity model has following technique effect:
1, the utility model U type tubular type inclining experiment device frock making is simple, and used unit all is existing parts, can gather materials on the spot at any time, be easy to find, and service time is longer, and is not fragile, long service life, thus save cost.
2, influenced by external factor less for the utility model U type tubular type inclining experiment device, compared with prior art, is not subjected to the size of measured ship, whether before and after the influence of pendulum, guarantee the accuracy of experimental result.
3, the utility model U type tubular type inclining experiment device less demanding to frock self compared with prior art, is not subjected to the length of cycloid, and the influence of material does not influence test findings, has guaranteed the accuracy of experimental result yet.

Embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
Embodiment 1: as shown in Figure 1, U type tubular type inclining experiment device comprises container 1, the U type pipe 2 that can adorn liquid, container 1 is provided with the opening that is in communication with the outside, one end of U type pipe 2 connects container 1, and the other end of U type pipe 2 is measured end 3, and measured end 3 is provided with altitude scale.Container 1 is communicated with U type pipe 2.Measured end can certainly be placed the measurer place that can measure height, so also can utilize measurer to read its reading.Measurer can be common ruler.
U type pipe 2 its those ends that connect container 1 are connected with container in the bottom of container 1, and this is to be connected the bottom center of container with the bottom surface of container in implementing.
During use, inject the water of certain altitude then in container, water does not have bubble, and current advance U type pipe.Press iron to be put in places different on the ship, ship will produce different degree of tilt, and water is also different at the height of measured end, as shown in Figure 1, measures length lambda, and the height α of variation moves the back corresponding data each time according to the order record of pressing iron to move then.
Then according to computing formula:
θ＝arctg(△L／α)
Promptly can draw heeling angle θ.
Embodiment 2: as shown in Figure 2, the characteristics of present embodiment are, described container 1 is by support 4 supportings, and support can be tripod.
Its that end that connects container of U type pipe is connected with container 1 by stop valve 5.Stop valve 5 can play the effect of controlling liquid.
Described measured end 3 is vertically, and described can tolerance measurer highly be ruler 6.
Described measured end 3 places the vertical column of angles 7 places, invests on the column of angles 7.
All the other are with embodiment 1.
During use, an end of U type pipe and the copper pipe on the container join, and the general water pipe that U type pipe is also available puts into U type pipe replaces, and opens stop valve then, make to be full of water in the water pipe, not bubble.The other end of water pipe (measured end) is then tied up on the column of angles.The column of angles should be placed in another side of a ship of ship in advance on request on the position of mark in advance, and binds steel ruler (ruler).Record data λ----U-shaped pipe two ends spacing, the height of water level is poor when the water level of △ L---inclination back water and initial level, also can be the poor of adjacent twice reading mean value, corresponding data after moving each time according to the order record of pressing iron to move then.Calculate according to formula then: θ=arctg (△ L/ λ) promptly can draw heeling angle.
The utility model U type tubular type inclining experiment device frock making is simple, and service time is longer, and is not fragile, thereby saves cost.It is less that the utility model U type tubular type inclining experiment device is influenced by external factor, also less demanding to self machine condition, guaranteed the accuracy of experimental result.
