DETAILED DESCRIPTION

[0037] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1 to 13 As shown, the present invention discloses a sample collection device for environmental data analysis, including a measuring rod 1 and a box body 2. The box body 2 is not a sealed structure, and a water sample can enter the box body 2. A scale 13 is arranged on the measuring rod 1 to facilitate the measurement of the depth of the water sample. A sleeve block 7 is fixedly connected to one side of the box body 2, and the sleeve block 7 can be sleeved outside the measuring rod 1. A rotatable base 4 is arranged in the box body 2, and a plurality of sampling boxes 3 are arranged on the base 4. The base 4 is a disc-shaped structure, and the plurality of sampling boxes 3 are arranged in a ring array on the base 4.

[0040] A toggle mechanism is provided on the inner wall of the box body 2, and a bottle mouth mechanism is provided on each sampling box 3. When the sampling box 3 is rotated to a predetermined position, the bottle mouth mechanism can cooperate with the toggle mechanism to open the bottle mouth mechanism, and the water sample can enter the sampling box 3 through the bottle mouth mechanism.

[0041] When one of the sampling boxes 3 is filled with water sample, the base 4 can rotate so that the next empty sampling box 3 can rotate to the side of the toggle mechanism.

[0042] There are two sets of blocks 7 , and a sliding plate 9 is arranged in the lower set of blocks 7 . After the water sample is poured into the sampling box 3 , the sliding plate 9 can slide horizontally for a predetermined distance, so that the box body 2 can slide downward along the measuring rod 1 .

[0043] When the device is implemented, the user first inserts the measuring rod 1 into the water body, and then installs the sampling box 3 in the box body 2, and opens the bottle mouth mechanism of the sampling box 3 that cooperates with the toggle mechanism at this time, and then puts the sleeve 7 on the outside of the measuring rod 1. After the user puts down the box body 2, due to the influence of its own gravity, the box body 2 can enter the water body, and the water sample can enter the sampling box 3 that cooperates with the toggle mechanism. As the water sample in the sampling box 3 increases, the sliding plate 9 can slide, so that the box body 2 can fall, and when the sampling box 3 falls to the lowest position, the base 4 rotates, so that the next empty sampling box 3 rotates to cooperate with the toggle mechanism, and the sampling box 3 filled with water samples can close its bottle mouth mechanism under the action of the toggle mechanism, and the next empty sampling box 3 can open its bottle mouth mechanism when cooperating with the toggle mechanism, so that the water sample enters the sampling box 3, and then repeats the above operation so that different sampling boxes 2 are filled with water samples of different depths.

[0044] In some embodiments, the box body 2 has an upper cover, which is rotatably mounted on the box body 2 and can be opened so as to install or remove the sampling box 3 therein.

[0045] A rotating block 5 is fixedly connected to the lower end of the base 4, and a fixed seat 6 is fixedly connected to the inner bottom wall of the box body 2. The rotating block 5 is sleeved outside the fixed seat 6, and a torsion spring 17 is arranged between the rotating block 5 and the fixed seat 6. After the sampling box 3 is installed on the base 4, the user rotates the base 4 counterclockwise so that the torsion spring 17 can be compressed and energized, so that the base 4 can rotate after the sampling box 3 is filled with water.

[0046] In order to enable the torsion spring 17 to release energy intermittently when the device is in use, so that the base 4 can rotate after the sampling box 3 at the corresponding position is filled with water samples each time, the following technical scheme is provided: a slide groove 11 is provided on the bottom surface of the base 4, and the slide groove 11 has a plurality of inclined groove units connected end to end, the inclined groove unit is a smooth curved surface structure, and a socket 12 is provided at the deepest position of each inclined groove unit, and a telescopic rod 23 is installed on the inner bottom wall of the box body 2, and the upper end of the telescopic rod 23 is pressed against the inclined groove unit, and when the upper end of the telescopic rod 23 is pressed against the step at the connection of the two inclined grooves, the telescopic rod 23 can prevent the base 4 from rotating, and the socket 12 is provided at the step.

[0047] The telescopic rod 23 can cooperate with the chute unit, so that after the sampling box 3 corresponding to the chute unit is filled with water samples, the telescopic rod 23 can be shortened, so that the torsion spring 17 releases energy, and after the telescopic rod 23 passes over a chute unit, it can immediately hit the wall of the next chute unit, so that when the sampling box 3 corresponding to the next chute unit is not filled with water samples, the telescopic rod 23 can prevent the base 4 from continuing to rotate.

[0048] In order to move the telescopic rod 23, the following technical solution is provided: a groove 14 for accommodating the sampling box 3 is opened on the base 4, and the number of the grooves 14 is the same as the number of the chute units. A receiving seat 15 capable of sliding up and down is provided in the groove 14, and a push rod 22 is fixedly connected to the lower end of the receiving seat 15, and a first spring 16 is provided between the receiving seat 15 and the base 4, so that after the water sample enters the sampling box 3, the first spring 16 can be compressed, and the push rod 22 extends downward and is inserted into the socket 12. After the water sample is poured into the sampling box 3, the sampling box 3 compresses the first spring 16, so that the push rod 22 presses the telescopic rod 23 downward and crosses the step at the connection between the two chute units.

[0049] By disposing the top rod 22 , the telescopic rod 23 can be moved.

[0050] The specific structure of the telescopic rod 23 is as follows: the lower end of the telescopic rod 23 is inserted into the fixed rod 24, and the fixed rod 24 is fixedly connected to the box body 2, and a second spring 25 is arranged between the telescopic rod 23 and the fixed rod 24, the groove 14 has a notch, and a fixed block 21 is fixedly connected to the side wall of the sampling box 3, and the fixed block 21 can pass through the notch and be inserted into the groove 14.

[0051] In order to make the box body 2 stop sliding down after falling a certain distance, the following technical solution is provided: a track 27 is provided on the surface of the measuring rod 1, a slider 26 is fixedly connected in the sleeve block 7, the slider 26 is located in the track 27, and a clamping block 8 is provided on the side of the measuring rod 1. There are multiple clamping blocks 8, which are arranged from top to bottom and are not connected to each other (the arrangement position of the clamping blocks 8 is as shown in FIG. Figure 2 As shown), the block 8 from top to bottom is gradually arranged in a direction close to the box body 2, and the sliding plate 9 can be pressed on the block 8.

[0052] When the sliding plate 9 is in use, it can first be placed on the uppermost block 8. When the sliding plate 9 slides to one side (the sampling box 3 at the corresponding position is filled with water samples), the sliding plate 9 is separated from the uppermost block 8. At this time, the sliding plate 9 cooperates with the block 8 of the second layer to prevent the box body 2 from continuing to slide downward until the box body 2 moves to the lowest position, which means that the sampling is completed. When the box body 2 moves to the bottom, the sliding plate 9 will no longer be able to slide downward to avoid the box body 2 from separating from the measuring rod 1, and it is convenient for the user to retract the box body 2.

[0053] A rotatable first gear 10 is provided on the inner wall of the box body 2, the sliding plate 9 extends into the box body 2, and the first gear 10 and the sliding plate 9 are meshed with each other. A second gear 20 is installed in the base 4, and the second gear 20 and the first gear 10 are meshed with each other. When the water sample is poured into the sampling box 3 and moves downward, the second gear 20 can rotate.

[0054] In some embodiments, in order to enable the sampling box 3 to perform sampling at a fixed position during sampling, the following technical solution is provided: the side wall of the receiving seat 15 is meshed with the second gear 20, and a limiting block 18 is fixed on the side wall of the receiving seat 15, and a limiting groove 19 is provided on the side wall of the groove 14, and there are two limiting grooves 19, which are arranged up and down, and the limiting block 18 can be inserted into the limiting groove 19, and the limiting block 18 can be squeezed to produce elastic deformation.

[0055] When the sampling box 3 is not filled with water sample, the limit block 18 cannot slide out of the upper limit slot 19, and when the sampling box 3 is filled with water sample, the limit block 18 can slide out of the upper limit slot 19 and enter the lower limit slot 19 under the weight of the sampling box 3 and the water therein. Of course, only one limit slot 19 can be provided, that is, when the empty sampling box 3 is placed on the receiving seat 15, the limit block 18 is located in the limit slot 19.

[0056] The bottle mouth mechanism includes a first through hole 28 and a baffle 30. The sampling box 3 is a box-mounted structure, and the first through hole 28 is arranged at the upper end of the sampling box 3. The baffle 30 is arranged in the sampling box 3, and the baffle 30 can rotate. A second through hole 29 is opened on the baffle 30, and the second through hole 29 is arranged alternately with the first through hole 28. The toggle mechanism includes a toggle tooth 31. A toggle gear 32 is also arranged in the baffle 30. The toggle gear 32 is meshed with the outer wall of the baffle 30 so that when the toggle gear 32 rotates, the baffle 30 can rotate accordingly. The toggle tooth 31 and the toggle gear 32 are meshed with each other.

[0057] When the base 4 rotates, the empty sampling box 3 can rotate accordingly and cooperate with the toggle mechanism. At this time, the baffle 30 can rotate and open accordingly. At this time, the telescopic rod 23 rests on the step of the inclined slot unit, and the base 4 cannot continue to rotate. When the sampling box 3 is filled with water samples, the base 4 can continue to rotate. At this time, the toggle tooth 23 can continue to toggle the toggle gear 32, thereby closing the baffle 30.

[0058] Racks are respectively provided on the receiving seat 15 , the sliding plate 9 and the shifting tooth 31 .

[0059] In order to avoid the first gear 10 and the second gear 20 from getting stuck, the contact surface between the first gear 10 and the second gear 20 can be reduced.
