Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

Example one

As shown in fig. 1-5, the utility model discloses a seawater sampling device, comprises a box bod 1, the vertical rotation in middle part is connected with pivot 11 in the box body 1, 1 downside of box body is equipped with the motor, the output shaft of motor runs through box body 1 and is connected with the transmission of pivot 11, box body 1 is equipped with and protects box 13 with motor assorted seal, 1 downside of box body is equipped with annular balancing weight 14, 1 upside of box body is equipped with four sampling barrels 15 that become the rectangular distribution, and four sampling barrel 15 upper ends are the opening, the equal sealed sliding connection of opening part of four sampling barrels 15 has sealed lid 16, all be equipped with the subassembly that opens and shuts between four sealed lids 16 and the pivot 11, 1 upside of box body is equipped with stand 17, the stand 17 upper end is equipped with through-hole 18, four sealed lid 16 upper ends all are equipped with stay cord 19.

When the seawater sampling device is used for sampling seawater, a rope on the external existing rope retracting device firstly passes through the through hole 18 on the upper side of the upright post 17, and the rope is tied on the upright post 17, at the moment, people only need to drive the boat to the sea surface needing to be sampled for sampling, the rope is gradually released through the rope releasing and releasing device, then people throw the sampling device into seawater, when the upper end of the sampling barrel 15 is positioned on the sea surface, the motor is started, the rotation of the motor drives the rotating shaft 11 to rotate 90 degrees, during the rotation of the rotating shaft 11, the sealing cover 16 in one of the sampling buckets 15 is pushed upwards out of the sampling bucket 15 through the opening and closing component, and then the sealing cover 16 is pulled back into the sampling bucket 15 again through the opening and closing component, the corresponding sampling barrel 15 is sealed, when the sealing cover 16 is pushed upwards out of the sampling barrel 15, the seawater can be rapidly filled into the corresponding sampling barrel 15, at the moment, the seawater sampling work of a seawater depth is completed, the rope is continuously released, the balance weight 14 arranged at the lower side of the box body 1 can ensure that the sampling device continuously moves to the sea water, the depth of the sampling device in the seawater can be roughly judged by the length of the rope released by the rope releasing and releasing device, so that when the sampling depth is reached, the motor can be started again, the motor drives the rotating shaft 11 to rotate 90 degrees again, the sealing cover 16 in another sampling barrel 15 is pushed out of the sampling barrel 15 and then pulled back in the same way, and the seawater can be rapidly filled into the sampling barrel 15, the four sampling barrels 15 can finish the sampling work of seawater at 1 to 4 different depths, and finally the seawater sampling device is pulled back by the rope retracting device, so that the sampling work of people on the seawater at different depths is very convenient and fast; the motor can be protected by the arranged sealing protection box 13, and the motor is prevented from being damaged by seawater; when the seawater needs to be taken out, the pull rope 19 on the corresponding sampling barrel 15 is pulled, the sealing cover 16 is pulled out of the sampling barrel 15, and finally the seawater is poured out of the sampling barrel 15; the utility model discloses make the staff can once only and convenient completion carry out the sample storage to the sea water of the different degree of depth, make sample staff's work to a certain extent simultaneously and simplify.

The opening and closing assembly comprises four ejector rods 2 and a shifting lever 21, one end of each of the four ejector rods 2 is fixedly connected with the lower ends of four sealing covers 16 respectively, the other ends of the four ejector rods 2 extend into the box body 1, the four ejector rods 2 are connected with the box body 1 in a sealing and sliding mode, the shifting lever 21 is fixedly connected with the rotating shaft 11, the shifting lever 21 is provided with an inclined plane 22, the lower ends of the four ejector rods 2 are matched with the height position of the inclined plane 22, and elastic members are arranged between the four ejector rods 2 and the inner wall of the upper side of the box body 1. Rotating shaft 11 rotates the driving lever 21 and rotates 90 degrees when 90 degrees, because four sampling barrels 15 are the setting of rectangle evenly distributed, so four ejector pins 2 also become the setting of rectangle evenly distributed, so driving lever 21 will make inclined plane 22 on the driving lever 21 contact with one of them ejector pin 2 in the process of rotating 90 degrees, and the guide through inclined plane 22 makes ejector pin 2 rebound, ejector pin 2 will extrude elastic component when rebound, can be simultaneously with sealed 16 ejecting sampling barrels 15 of lid, after driving lever 21 has rotated 90 degrees, driving lever 21 will break away from completely and correspond the contact of ejector pin 2, so ejector pin 2 will reset thereupon under elastic component's self elasticity effect that resets this moment, thereby accomplish the sample and the storage function to the sea water, and ejector pin 2 and box body 1 sealing sliding connection, so the sea water in four sampling barrels 15 all can't get into box body 1 internal mixing.

The elastic component comprises a cylinder 3 with a closed lower end, the cylinder 3 is fixedly connected with the upper side wall of the box body 1, a ring piece 31 is connected in the cylinder 3 in a sliding mode, the ring piece 31 is fixedly connected with the ejector rod 2, the ejector rod 2 penetrates through the lower end of the cylinder 3, and a spring 32 is arranged between the ring piece 31 and the upper side wall of the box body 1. When the ejector rod 2 moves upwards, the ring piece 31 is driven to move upwards in the cylinder 3, the ring piece 31 moves upwards to be matched with the upper side wall of the box body 1, so that the spring 32 is stressed to contract, when the ejector rod 2 is separated from contact with the deflector rod 21, the spring 32 is reset through self elasticity, the ring piece 31 is pushed to move downwards to reset, and finally the ring piece 31 drives the ejector rod 2 to move downwards to reset; the lowermost side of the cylinder 3 is higher than the uppermost side of the lever 21, so that the lever 21 can normally rotate.

Example two

As a further optimization of the previous embodiment, the lower end of the carrier rod 2 is rounded as shown in FIGS. 4 to 5. The push rod 2 is more smooth when contacting with the inclined surface 22 on the shift lever 21, so that the push rod 2 can move upwards relatively stably.

The side surfaces of the four sealing covers 16 are provided with annular mounting grooves 4, sealing rings 41 are arranged in the four annular mounting grooves 4, and the four sealing rings 41 are respectively abutted against the inner walls of the four sampling barrels 15. Through installing sealing washer 41 and the inner wall looks butt of sampling bucket 15 in annular mounting groove 4, make sealed lid 16 can be better with the inside sealed of sampling bucket 15 like this.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
