Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and the utility model is described.
Fig. 1 and Fig. 2 respectively illustrates main TV structure and the plan structure of the density of sea water sampling sharp-pointed tube of the utility model embodiment, and as depicted in figs. 1 and 2, density of sea water sampling sharp-pointed tube comprises:
Water intaking cylinder 3, for holding seawater;
Upper cover 1, cover on described water intaking cylinder 1, described upper cover 1 comprises: the connecting portion 13 be connected with described water intaking cylinder, the hinge 10 be fixedly connected with described connecting portion, the elastic device (in figure independent label) being hinged on the removable cover (in figure independent label) on described hinge 10 and being connected between described removable cover and described connecting portion, described removable cover has initial position and open position, at initial position, described water intaking cylinder closed by described removable cover, in open position, described water intaking cylinder opened by described removable cover.
Density of sea water sampling sharp-pointed tube of the present utility model is before dropping to the drauht centre position calculated, due to the effect of elastic device, sampling sharp-pointed tube is in air-tight state always, after sampling sharp-pointed tube dive to the drauht centre position calculated, because the degree of depth increases, the seawater pressure of this middle position is greater than the pressure of seawater surface, and thus removable cover is opened, and seawater enters sampling sharp-pointed tube.Along with the rising of sampling sharp-pointed tube, seawater pressure decline, elastic device reply, removable cover close, after leaving the water, open removable cover envelope or back out upper cover, to water intaking cylinder in insert densitometer, can obtain and surveying vessel in position density of sea water.
Further, as Fig. 1 and Fig. 2, further, described connecting portion 13 is annular, and described water intaking cylinder 3 is cylinder, so that the socket both realizing, is also convenient to being threaded both realizing.Be connected on described water intaking cylinder 3 in described connecting portion 13.The external diameter of connecting portion 13 is less than the internal diameter of water intaking cylinder 3, to reduce the volume of upper cover, under equivalent weight, increases the useful volume of density of sea water sampling sharp-pointed tube.
Described removable cover comprises: left removable cover 11 and right removable cover 12, and described left removable cover 11 is identical with right removable cover 12 shape and be symmetrical arranged about described hinge.Like this, convenient making, also fast and easy water inlet, water completely rear Quick-return, quick closure, guarantee can not be obscured with upper ocean water.
Further, described left removable cover 11 and right removable cover 12 are semicircle, like this, are convenient to make.
Further, described elastic device is spring, and such as described left removable cover 11 and right removable cover 12 are connected on connecting portion 13 respectively by spring 14 and spring 16.Use spring, cost is low, be convenient to make, install and change.
Further, described connecting portion 13 is threaded connection with described water intaking cylinder 3, and connecting portion 13 is provided with external thread, and water intaking cylinder 3 is provided with internal thread, is convenient to installation and removal, backs out upper cover fast, detect after being convenient to water intaking.
Further, described connecting portion 13 comprises: interconnective bottom thread portion 131 and upper suspension portion 133, and described bottom thread portion 131 has external thread, is threaded connection with described water intaking cylinder 3.Upper suspension portion 133 is connected with described elastic device, and upper suspension portion 133 is annular, which is provided with hook, for hanging elastic device, and such as spring.In the cavity of spring between upper suspension portion 133 and removable cover, like this, the setting of spring, without the need to taking other spaces, is conducive to compact conformation, increase the useful volume that seawater holds, and spring can be protected.
Described connecting portion 13 also comprises: the brace table 135 of annular, be arranged on the outside in bottom thread portion 131, for spacing to connecting portion 13, whole upper cover is played a supporting role simultaneously, make the connection of upper cover more stable, minimizing is stressed with described water intaking cylinder 3 connection of thread, ensures the stable of water intaking process.
Further, as shown in Figure 1, the initial position of described removable cover is horizontal level, and at initial position, described removable cover is equal with the distance on the bottom in described bottom thread portion and the top in described upper suspension portion.Like this, removable cover can be made after water intaking process and water intaking can to have sufficient activity space, ensure that the smoothness of water intaking is smooth.
Further, as shown in Figure 1, described hinge 10 is greater than zero, to enable removable cover smooth opening with the distance of described spring 14 and spring 16.
Further, as shown in Figure 1, at initial position, described spring 14 and spring 16 intersect with surface level the angle being greater than zero degree and being less than 90 degree.The pulling force of the gravity of seawater and spring can be made like this to form the angle being greater than zero degree and being less than 90 degree, removable cover can not be made not open, removable cover also can not be made to open rear pass and do not go up, ensure that the validity of water intaking.
The course of work of the present utility model is as follows: by scale amount line and cable guiding device, water intaking cylinder is positioned over midship draft position, density of sea water sampling sharp-pointed tube is in decline process, due to the effect of elastic device, sampling sharp-pointed tube is in air-tight state always, after sampling sharp-pointed tube dive to the drauht centre position calculated, because the degree of depth increases, the seawater pressure of this middle position is greater than the pressure of seawater surface, thus removable cover is opened, and seawater enters sampling sharp-pointed tube.Along with the rising of sampling sharp-pointed tube, seawater pressure declines, and elastic device is replied, and removable cover is closed.After leaving the water, open removable cover envelope or back out upper cover, to water intaking cylinder in insert densitometer, can obtain and surveying vessel in position density of sea water.
After sampling sharp-pointed tube exploitation of the present utility model, expectation can improve Weight by Draft precision per mille, and with handling capacity 200,000,000 tons, value of goods, by being 500 yuans of rough calculation per ton, will retrieve a loss 12,000,000 yuans for trade side.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.For each ingredient of the present utility model can mutually combine under the condition of not conflicting; any those skilled in the art; equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
