Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to an environmental information collection device. Background Art

[0002] When sampling water bodies, especially in lakes and rivers, the depth of the water body is deep, and it is troublesome to collect water samples at different depths of the water body. For deep water bodies, due to the uncertainty of the depth of the water body, it is also troublesome to collect water samples at different depths. In addition, in the prior art, when sampling water bodies of different depths, most of the sampling is done by samplers on the water surface. However, for deeper water bodies, the method of sampling on the water surface is obviously not enough.

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.

[0043] Example 1

[0044] like Figures 1 to 17 As shown, the present invention discloses an environmental information collection device, including a measuring mechanism, a sampling mechanism and a prompting mechanism.

[0045] The measuring mechanism includes a measuring rod 1, on which a scale 13 is provided, and a block 8 capable of moving up and down is also provided on the measuring rod 1, the number of the blocks 8 is multiple, the blocks 8 are distributed in the vertical direction, and the blocks 8 from top to bottom gradually approach the box body 2, a connecting rod 34 is fixedly connected to the block 8, a positioning groove 39 is provided on one side of the measuring rod 1, a rotatable positioning bolt 36 is provided on the connecting rod 34, one end of the positioning bolt 36 is inserted into the positioning groove 39, and after the positioning bolt 36 rotates a predetermined angle, the positioning bolt 36 can fix the position of the connecting rod 34 and the block 8,

[0046] As shown in the figure, when the narrower part of the positioning bolt 36 contacts the two side walls of the positioning groove 39, the rotating bolt 36 can slide up and down therein, so that the user can adjust its height. When the user needs to fix it, the user only needs to rotate the rotating bolt 36, and the wider part of the rotating bolt 36 abuts against the inner wall of the positioning groove 39, so that the purpose of fixing can be achieved. In order to ensure that the user can adjust the height more conveniently, the scale 13 and the block 8 are located on the same side of the measuring rod 1.

[0047] The sampling mechanism includes a box body 2 and a sampling box 3. The sampling box 3 is installed in the box body 2, and there are multiple sampling boxes 3. The sampling box 3 can collect water samples. A sliding plate 9 that can slide horizontally is arranged on the box body 2. The sliding plate 9 can be placed on the card block 8 from top to bottom, so that the box body 2 stays at different heights, thereby sampling water bodies at different depths.

[0048] The prompt mechanism includes an indicator rod 38, and a support plate 33 is fixedly connected to the side of the measuring rod 1. The support plate 33 is located below the block 8. After the sliding plate 9 falls from the block 8, it can stay on the support plate 33, and when the sliding plate 9 is pressed on the support plate 33, the indicator rod 38 can be lifted upward and extended to the outside of the top of the measuring rod 1.

[0049] When the sliding plate 9 falls on the supporting plate 33, it means that the sliding plate 9 falls to the bottom (sampling is completed), and the indicating rod 38 is lifted upward to prompt the user that the sampling operation is completed, and the user can lift the measuring rod 1 upward.

[0050] Regarding how to lengthen the measuring rod 1, the following technical solution is provided: the measuring rod 1 includes a main rod 101 and a secondary rod 102, a base plate 105 is installed at the lower end of the main rod 101, the base plate 105 is a mesh structure, a plug-in slot 103 is opened at the upper end of the main rod 101, and a plug-in block 104 is installed at the lower end of the secondary rod 102, and the plug-in block 104 can be inserted into the plug-in slot 103.

[0051] Of course, there can be multiple auxiliary rods 102. The base plate 105 can be disassembled to prevent the lower end of the main rod 101 from being inserted into the mud.

[0052] A first positioning block 106 is fixedly connected to the plug-in block 104, and a limiting plate 107 is also fixedly connected to the upper end of the plug-in block 104. A second positioning block 108 is fixedly connected to the side of the limiting plate 107. The first positioning block 106 and the second positioning block 108 are both made of elastic material. A second positioning blind hole 110 that cooperates with the second positioning block 108 is arranged in the auxiliary rod 102, and a third positioning blind hole 111 and a first positioning blind hole 109 are respectively arranged in the auxiliary rod 102 and the main rod 101. The third positioning blind hole 111 and the first positioning blind hole 109 can cooperate with the first positioning block 106.

[0053] When the user pulls the plug-in block 104 downward, the second positioning block 108 can enter the second positioning blind hole 110, so that the plug-in block 104 can remain stable. When the plug-in block 104 is inserted into the main rod 101, the first positioning block 106 cooperates with the first positioning blind hole 109, so that the main rod 101 is connected to the auxiliary rod 102, and during the connection process, the second positioning block 108 can always be in the second positioning blind hole 110.

[0054] The plug-in block 104 and the limiting plate 107 are an integrated structure, and a split body 103 is also provided on the secondary rod 102 . After the plug-in block 104 and the limiting plate 107 are installed in the T-slot 112 , the split body 103 is welded to the secondary rod 102 .

[0055] The third positioning blind hole 111 can clamp the plug-in block 104 in the auxiliary rod 102 when the plug-in block 104 is not in use.

[0056] There is no support plate 33 on the secondary rod 102 .

[0057] It also includes an energy storage mechanism, a rotating mechanism, a limiting mechanism and a connecting mechanism.

[0058] The energy storage mechanism is used to store energy to drive the rotating mechanism to rotate. The energy storage mechanism is a torsion spring 17.

[0059] The rotating mechanism is used to drive the sampling box 3 to rotate, so that the sampling box 3 that has been sampled can be rotated to the subsequent station, and the sampling box 3 that is not empty can be rotated to the sampling station.

[0060] The connecting mechanism is used to connect the box body 2 to the measuring rod 1 and enable the box body 2 to slide along the measuring rod 1.

[0061] The limiting mechanism is used to limit the energy storage mechanism so that it can only drive the rotating mechanism to rotate a predetermined angle each time.

[0062] A plug 35 is inserted into one end of the positioning bolt 36, and the plug 35 is inserted into the positioning bolt 36 and can drive the positioning bolt 36 to rotate. A fixed head is provided on one end of the positioning bolt 36 located in the positioning groove 39. The fixed head is elliptical and has a flat surface to facilitate the user to select and use the card block 8, that is, the card block 8 together with the connecting rod 34 is sleeved on the positioning bolt 36. The user can connect the card block 8 to the measuring rod 1 when needed, and can remove it when it is not needed.

[0063] A rotating rod 37 is disposed in the support plate 33 , one end of the rotating rod 37 extends outside the upper end of the support plate 33 , and the other end extends into the measuring rod 1 , and the lower end of the indicating rod 38 is pressed on the rotating rod 37 .

[0064] When the main rod 101 is connected to the auxiliary rod 102, the indicator rod 38 in the auxiliary rod 102 can be pressed on the upper end of the indicator rod 38 in the main rod 101, so that when the indicator rod 38 in the main rod 101 is pushed upward, the indicator rod 38 in the auxiliary rod 102 can be pushed upward accordingly. Of course, the indicator rod 38 can be set to a T-shaped structure with a larger upper part and a smaller lower part to prevent the indicator rod 38 from falling off.

[0065] The steps to use are as follows:

[0066] S1, insert the measuring mechanism into the water body and measure the depth of the water body.

[0067] S2, according to the depth of the water body, the height of the card block 8 is adjusted to collect water samples at different depths.

[0068] S3, after the adjustment of the block 8 is completed, the measuring mechanism is inserted into the water body again and its position is fixed.

[0069] S4, connecting the sampling mechanism to the measuring mechanism, and then the sampling mechanism performs sampling,

[0070] S5, after the sampling is completed, the prompt mechanism can rise to prompt the user that the sampling is completed. At this time, the measuring mechanism is pulled upward, and the sampling mechanism can move upward until it leaves the water surface.

[0071] For the specific matching structure of the sampling box 3 and the box body 2, the following technical solution is provided: the rotating mechanism includes a base 4, the base 4 is installed in the box body 2, and the base 4 can rotate in the box body 2, there are multiple sampling boxes 3, and they are distributed on the base 4 in a circular array,

[0072] A toggle mechanism is provided on the inner wall of the box body 2, and a bottle mouth mechanism is provided on the 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.

[0073] 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.

[0074] The connecting mechanism includes a sleeve block 7, which is fixedly connected to one side of the sampling box 3. The sleeve block 7 is sleeved outside the measuring rod 1, and a sliding plate 9 is arranged inside the sleeve block 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.

[0075] 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 3 are filled with water samples of different depths.

[0076] 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.

[0077] 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: the limiting mechanism is a telescopic rod 23, and a slide groove 11 is provided on the bottom surface of the base 4. The slide groove 11 has a plurality of inclined groove units connected end to end. The inclined groove unit is a smooth curved structure, and a socket 12 is provided at the deepest position of each inclined groove unit. 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. 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.

[0078] 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.

[0079] 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.

[0080] By disposing the top rod 22 , the telescopic rod 23 can be moved.

[0081] 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.

[0082] In other embodiments, in order to enable the box body 2 to stop sliding down after falling a certain distance, the following technical solution is provided: a track 27 is opened on the surface of the measuring rod 1, a slider 26 is fixedly connected in the sleeve block 7, and the slider 26 is located in the track 27.

[0083] 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 (falls down under the action of gravity). 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 (that is, it falls on the support plate 33), 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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 31 can continue to toggle the toggle gear 32, thereby closing the baffle 30.

[0089] Racks are respectively provided on the receiving seat 15 , the sliding plate 9 and the shifting tooth 31 .

[0090] 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.
