Description

Technical Field

[0001] The present invention relates to the technical field of soil and water monitoring, and particularly to a continuous sampling and preservation device for soil and water conservation monitoring. Background Art

[0002] Soil and water conservation monitoring refers to the long-term investigation, observation and analysis of the occurrence, development, harm of soil erosion and the benefits of soil and water conservation. Through soil and water conservation monitoring, the types and development laws of soil erosion are clarified, which is of great significance for various measures of comprehensive treatment of soil erosion. During the process of soil and water conservation monitoring, it is necessary to take samples of soil multiple times.

[0003] According to a preservation device for continuous sampling in soil and water conservation monitoring proposed in Chinese Patent CN214268532U, when the device is in use, the obtained samples are placed in a sample storage bottle, and then the sample storage bottle is placed in a fixing component. There are multiple groups of the fixing components, which are convenient for storing the sample storage bottles separately to avoid confusion of multiple samples, thereby ensuring subsequent detection. A support plate is arranged at the lower end of the fixing component, and a shock-absorbing spring is arranged at the lower end of the support plate. The shock-absorbing spring can reduce the vibration transmitted from the storage box to the fixing component and avoid damaging the sample storage bottle in the fixing component when the storage box is collided, ensuring the safety of the samples and improving the practicability of the device.

[0004] However, there are still some deficiencies in this patent. The way of clamping and fixing the sample storage bottle inside the storage box of this device is to fix the sample storage bottle through the extrusion force of a return spring, a movable ring and a rubber pad. However, this device cannot clamp and fix sample storage bottles with different heights and outer diameters for storage, which affects the applicable range of the device and thus affects the storage effect of the device on soil and water. For this reason, we propose a continuous sampling and preservation device for soil and water conservation monitoring. Summary of the Invention

[0005] The purpose of the present invention is to provide a continuous sampling and preservation device for soil and water conservation monitoring, which solves the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A continuous sampling and preservation device for soil and water conservation monitoring includes a storage box and an adjustment component arranged inside the storage box. The adjustment component includes a bottom plate fixedly connected to the bottom of the inner wall of the storage box. A sponge block is fixedly connected to the top of the middle part of the bottom plate. A first electric push rod is fixedly connected to the top of the side of the bottom plate. The output end of the first electric push rod is fixedly connected to a lifting plate. The outer wall of the lifting plate is slidably connected to the inner wall of the storage box. A through groove is opened inside the lifting plate. Through the adjustment component, it is convenient to adjust the height of the lifting plate, so as to store sample storage bottles with different heights.

[0007] Preferably, the adjusting assembly also includes a fixing bracket fixedly connected to the top of the lifting plate, the top inner wall of the fixing bracket is fixedly connected to the forward and reverse motor, the output end of the forward and reverse motor is fixedly connected to the first rotating rod, the bottom outer wall of the first rotating rod is fixedly connected to a butterfly-shaped rotating block, the outer wall of the butterfly-shaped rotating block is slidably connected to the F-shaped displacement block, the bottom of the F-shaped displacement block is slidably connected to the top of the lifting plate, the outer wall of the F-shaped displacement block is fixedly connected to the limiting block, the inner wall of the other side of the limiting block is slidably connected to the limiting column, the other end of the limiting column is fixedly connected to the vertical plate, the bottom of the vertical plate is fixedly connected to the top of the lifting plate, the top side wall of the vertical plate is fixedly connected to a compression spring, and the other end of the compression spring is fixedly connected to the side wall of the limiting block. When the sample bottle is placed inside the lifting plate, In order to improve the stability of the sample bottles during the storage process, it is necessary to clamp and fix the sample bottles. At this time, the operator starts the forward and reverse motors to cause the first rotating rod to rotate. After the first rotating rod rotates, the butterfly-shaped rotating block will be caused to rotate. During the rotation of the butterfly-shaped rotating block, its outer wall will squeeze the two F-type displacement blocks. Since the set limit blocks and limit columns limit the F-type displacement blocks, the butterfly-shaped rotating block squeezes the two F-type displacement blocks, causing the two F-type displacement blocks to move alternately and approach each other, so that the inner sides of the two F-type displacement blocks can squeeze the outer wall of the sample bottle, thereby clamping the sample bottle. In this process, sample bottles with different outer diameters can be clamped and fixed, thereby improving the stability of the device when storing sample bottles after water and soil sampling.

[0008] Preferably, a shock-absorbing assembly is provided at the bottom of the storage box, and the shock-absorbing assembly includes a rectangular support frame fixedly connected to the bottom of the storage box, a shock-absorbing spring fixedly connected to the top of the inner wall of the rectangular support frame, the other end of the shock-absorbing spring fixedly connected to a slider, the outer portion of the slider is slidably connected to the bottom inner wall of the rectangular support frame, the bottom of the slider is fixedly connected to a connecting column, the bottom of the connecting column is fixedly connected to a U-shaped block, the top side wall of the U-shaped block is fixedly connected to a cross plate, the bottom of the storage box is fixedly connected to a damper, and the other end of the damper is connected to the top of the cross plate The U-shaped block is fixedly connected, and the inner wall of the U-shaped block is rotatably connected to the second rotating rod through a bearing, and the outer wall of the second rotating rod is fixedly connected to a roller. By setting a shock-absorbing component, after the storage of the sample bottle is completed, when the device needs to be transported, it is easy to encounter uneven road conditions. At this time, the roller will compress the connecting column through the U-shaped block, so that the connecting column squeezes the slider, and the slider compresses the shock-absorbing spring. In the process of moving the U-shaped block, the cross plate will be prompted to move. Under the action of the damper, it can cooperate with the shock-absorbing spring to achieve shock absorption of the device, thereby improving the stability of the device during transportation.

[0009] Preferably, the shock absorption assembly further includes a connecting plate fixedly connected to the side wall of the cross plate. The top of the connecting plate is fixedly connected with a rectangular frame. The inner wall of the rectangular frame is fixedly connected with a cross column. The outer wall of the cross column is slidably connected with a moving block. The side wall of the moving block is fixedly connected with a return spring. The other end of the return spring is fixedly connected with the inner wall of the rectangular frame. The top of the moving block is movably connected with a rotating plate through a hinge. The other end of the rotating plate is movably connected with the bottom of the storage box through a hinge. When the cross plate vibrates and moves, it will drive the connecting plate to move, and cooperate with the rotating plate to rotate, so that the rotating plate pushes the moving block to move along the outer wall of the cross column, and compresses the return spring. With the cooperation of the shock absorption spring and the damper, the purpose of further damping the device can be achieved.

[0010] Preferably, the shock absorption assembly further includes a connecting frame fixedly connected to the bottom of the cross plate. The inner wall of the bottom of the connecting frame is fixedly connected with a driving motor. The output end of the driving motor is fixedly connected with a lead screw. The outer wall of the lead screw is threadedly connected with a socket block. The top of the socket block is slidably connected with the bottom of the cross plate. The bottom side wall of the socket block is fixedly connected with an insertion post. The outer wall of the other end of the insertion post is slidably connected with the side inner wall of the roller. An embedding groove adapted to the outer wall of the insertion post is provided on the side wall of the U-shaped block. When it is necessary to limit the roller after the device is transported, the operator starts the driving motor to make the lead screw rotate. During the rotation of the lead screw, the socket block will be driven to move along the outer wall of the lead screw and push the insertion post to move. When the insertion post enters the embedding groove on the side wall of the U-shaped block and then enters the side inner wall of the roller, the roller can be limited, and the position of the device can be fixed.

[0011] Preferably, a plurality of card slots are circumferentially arranged on the side wall of the roller. The inner diameter of the card slot is adapted to the outer wall of the other end of the insertion post. By arranging a plurality of card slots on the side inner wall of the roller, it is convenient for the insertion post to enter the inside of the card slot, so as to limit the roller and thus limit the device.

[0012] Preferably, a push rod is fixedly connected to the outer wall of the storage box. The top of the storage box is movably connected with a box cover through a hinge. The top of the box cover is fixedly connected with a handle. By arranging a push rod on the outer wall of the storage box, it is convenient for the operator to apply pressure to the push rod and cooperate with the rotation of the roller to transport the device. By arranging a box cover on the top of the storage box, it is convenient for the operator to rotate the box cover to the top of the storage box after storing the sample bottle, so as to store the sample bottle.

[0013] Preferably, there are three groups of the F-shaped displacement blocks, and there are two F-shaped displacement blocks in each group. Every two F-shaped displacement blocks are arranged staggeredly. By arranging three groups of F-shaped displacement blocks, it is convenient to clamp and fix multiple sample storage bottles inside the storage box, thereby improving the stability of the device during the storage process of the sample storage bottles.

[0014] The present invention provides a continuous sampling and preservation device for soil and water conservation monitoring. The continuous sampling and preservation device for soil and water conservation monitoring has the following beneficial effects:

[0015] (1) For the continuous sampling and preservation device for soil and water conservation monitoring, when it is necessary to store the sample storage bottles after soil and water sampling through the adjustment component, since the lengths of different types of sample storage bottles are often inconsistent, it is necessary to adjust the storage height of the sample storage bottles inside the storage box according to the height of the sample storage bottles. At this time, the operator starts the first electric push rod to make the first electric push rod extend and push the lifting plate to rise. When the height of the lifting plate rises to a certain position, the operator places the sample storage bottle in the through groove inside the lifting plate so that the bottom of the sample storage bottle contacts the sponge block, thereby preventing the sample storage bottle from being damaged due to being knocked during transportation. After the sample storage bottle is placed inside the lifting plate, in order to improve the stability of the sample storage bottle during the preservation process, it is necessary to clamp and fix the sample storage bottle. At this time, the operator starts the forward and reverse motor to make the first rotating rod rotate. After the first rotating rod rotates, it will make the butterfly-shaped rotating block rotate. During the rotation of the butterfly-shaped rotating block, its outer wall will squeeze the two F-shaped displacement blocks. Due to the limiting effect of the set limiting block and limiting column on the F-shaped displacement blocks, under the squeezing action of the butterfly-shaped rotating block on the two F-shaped displacement blocks, the two F-shaped displacement blocks will move staggeredly and approach each other, so that the inner sides of the two F-shaped displacement blocks squeeze the outer wall of the sample storage bottle, thereby realizing the clamping of the sample storage bottle. In this process, it is convenient to clamp and fix sample storage bottles with different outer diameters, thereby improving the stability of the device when storing the sample storage bottles after soil and water sampling;

[0016] (2) The continuous sampling and storage device for soil and water conservation monitoring is provided with a shock-absorbing component. After the storage of the sample bottles is completed, when the device needs to be transported, it is easy to encounter uneven road conditions. At this time, the roller will compress the connecting column through the U-shaped block, so that the connecting column squeezes the slider, and the slider compresses the shock-absorbing spring. During the movement of the U-shaped block, the cross plate will be prompted to move. Under the action of the damper, it can cooperate with the shock-absorbing spring to achieve shock absorption of the device, thereby improving the stability of the device during transportation. When the cross plate vibrates and moves, it will move with the connecting plate and cooperate with the rotating plate to produce The cam is rotated to make the rotating plate push the moving block to move along the outer wall of the horizontal column, and compress the return spring and cooperate with the shock-absorbing spring and the damper to further achieve the purpose of shock-absorbing the device. When the device is transported and the roller needs to be limited, the operator starts the drive motor to cause the screw rod to rotate. During the rotation of the screw rod, the sleeve block will be prompted to move along the outer wall of the screw rod and push the plug column to move, so that the plug column enters the embedded groove of the side wall of the U-shaped block and then enters the side inner wall of the roller, thereby limiting the roller and fixing the position of the device.

Detailed implementation manners

[0027] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0028] A preferred embodiment of a continuous sampling and preservation device for soil and water conservation monitoring provided by the present invention is as Figures 1 to 9 shown: A continuous sampling and preservation device for soil and water conservation monitoring includes a storage box 1 and an adjusting component 41 arranged inside the storage box 1. The adjusting component 41 includes a bottom plate 411 fixedly connected to the bottom of the inner wall of the storage box 1. A sponge block 412 is fixedly connected to the top of the middle of the bottom plate 411. A first electric push rod 413 is fixedly connected to the top of the side of the bottom plate 411. The output end of the first electric push rod 413 is fixedly connected to a lifting plate 414. The outer wall of the lifting plate 414 is slidably connected to the inner wall of the storage box 1. A through groove 415 is opened inside the lifting plate 414. Through the adjusting component 41, when it is necessary to store the sample bottles after soil and water sampling, since the lengths of different types of sample bottles are often inconsistent, it is necessary to adjust the storage height of the sample bottles inside the storage box 1 according to the height of the sample bottles. At this time, the operator starts the first electric push rod 413 to extend the first electric push rod 413 and push the lifting plate 414 to rise. When the height of the lifting plate 414 rises to a certain position, the operator places the sample bottle in the through groove 415 inside the lifting plate 414 so that the bottom of the sample bottle contacts the sponge block 412, thereby preventing the sample bottle from being damaged due to being knocked during transportation.

[0029] The adjusting assembly 41 further includes a fixing frame 416 fixedly connected to the top of the lifting plate 414. A forward and reverse motor 417 is fixedly connected to the inner wall of the top of the fixing frame 416. The output end of the forward and reverse motor 417 is fixedly connected to a first rotating rod 418. A butterfly-shaped rotating block 419 is fixedly connected to the outer wall of the bottom of the first rotating rod 418. An F-shaped displacement block 4110 is slidably connected to the outer wall of the butterfly-shaped rotating block 419. The bottom of the F-shaped displacement block 4110 is slidably connected to the top of the lifting plate 414. A limiting block 4111 is fixedly connected to the outer wall of the F-shaped displacement block 4110. A limiting post 4112 is slidably connected to the inner wall of the other side of the limiting block 4111. The other end of the limiting post 4112 is fixedly connected to a vertical plate 4113. The bottom of the vertical plate 4113 is fixedly connected to the top of the lifting plate 414. A compression spring 4114 is fixedly connected to the side wall of the top of the vertical plate 4113. The other end of the compression spring 4114 is fixedly connected to the side wall of the limiting block 4111. After the sample storage bottle is placed inside the lifting plate 414, in order to improve the stability of the sample storage bottle during storage, it is necessary to clamp and fix the sample storage bottle. At this time, the operator starts the forward and reverse motor 417 to cause the first rotating rod 418 to rotate. After the first rotating rod 418 rotates, it will cause the butterfly-shaped rotating block 419 to rotate. During the rotation of the butterfly-shaped rotating block 419, its outer wall will squeeze the two F-shaped displacement blocks 4110. Due to the limiting effect of the arranged limiting block 4111 and limiting post 4112 on the F-shaped displacement blocks 4110, under the squeezing action of the butterfly-shaped rotating block 419 on the two F-shaped displacement blocks 4110, the two F-shaped displacement blocks 4110 will move alternately and approach each other, so that the inner sides of the two F-shaped displacement blocks 4110 squeeze the outer wall of the sample storage bottle, thereby realizing the clamping of the sample storage bottle. In this process, it is convenient to clamp and fix sample storage bottles with different outer diameters, thereby improving the stability of the device when storing the sample storage bottles after soil and water sampling.

[0030] A preferred embodiment of the continuous sampling and preservation device for soil and water conservation monitoring provided by the present invention is as follows Figures 1 to 9As shown in the figure: A shock absorption component 42 is provided at the bottom of the storage box 1. The shock absorption component 42 includes a rectangular support frame 421 fixedly connected to the bottom of the storage box 1. At the top of the inner wall of the rectangular support frame 421, a shock absorption spring 422 is fixedly connected. The other end of the shock absorption spring 422 is fixedly connected to a slider 423. The outside of the slider 423 is slidably connected to the bottom inner wall of the rectangular support frame 421. At the bottom of the slider 423, a connecting column 424 is fixedly connected. At the bottom of the connecting column 424, a U-shaped block 425 is fixedly connected. On the top side wall of the U-shaped block 425, a cross plate 426 is fixedly connected. At the bottom of the storage box 1, a damper 427 is fixedly connected. The other end of the damper 427 is fixedly connected to the top of the cross plate 426. Inside the U-shaped block 425, a second rotating rod 4215 is rotatably connected through a bearing. On the outer wall of the second rotating rod 4215, a roller 4214 is fixedly connected. By providing the shock absorption component 42, after the sample storage bottles are stored and when the device needs to be transported, it is easy to encounter uneven road surfaces. At this time, the roller 4214 will compress the connecting column 424 through the U-shaped block 425, causing the connecting column 424 to squeeze the slider 423, making the slider 423 compress the shock absorption spring 422. During the movement of the U-shaped block 425, it will cause the cross plate 426 to move. Under the action of the damper 427, it can cooperate with the shock absorption spring 422 to achieve shock absorption for the device and improve the stability of the device during transportation.

[0031] The shock absorption component 42 further includes a connecting plate 428 fixedly connected to the side wall of the cross plate 426. At the top of the connecting plate 428, a rectangular frame 4216 is fixedly connected. Inside the rectangular frame 4216, a cross column 4217 is fixedly connected. A moving block 4218 is slidably connected to the outer wall of the cross column 4217. On the side wall of the moving block 4218, a reset spring 4219 is fixedly connected. The other end of the reset spring 4219 is fixedly connected to the inner wall of the rectangular frame 4216. The top of the moving block 4218 is movably connected to a rotating plate 4220 through a hinge. The other end of the rotating plate 4220 is movably connected to the bottom of the storage box 1 through a hinge. When the cross plate 426 vibrates and moves, it will drive the connecting plate 428 to move and cooperate with the rotating plate 4220 to rotate, causing the rotating plate 4220 to push the moving block 4218 to move along the outer wall of the cross column 4217 and compress the reset spring 4219. Under the combined action of the shock absorption spring 422 and the damper 427, the purpose of further shock absorption for the device can be achieved.

[0032] The shock absorption assembly 42 further includes a connecting frame 429 fixedly connected to the bottom of the cross plate 426. A driving motor 4210 is fixedly connected to the inner wall of the bottom of the connecting frame 429. The output end of the driving motor 4210 is fixedly connected to a lead screw 4211. A socket block 4212 is threadedly connected to the outer wall of the lead screw 4211. The top of the socket block 4212 is slidably connected to the bottom of the cross plate 426. A plug post 4213 is fixedly connected to the bottom side wall of the socket block 4212. The outer wall of the other end of the plug post 4213 is slidably connected to the inner side wall of the roller 4214. An embedding groove adapted to the outer wall of the plug post 4213 is formed in the side wall of the U-shaped block 425. When the device is transported, when it is necessary to limit the roller 4214, the operator starts the driving motor 4210 to cause the lead screw 4211 to rotate. During the rotation of the lead screw 4211, the socket block 4212 will move along the outer wall of the lead screw 4211 and push the plug post 4213 to move. After the plug post 4213 enters the embedding groove in the side wall of the U-shaped block 425, it then enters the inner side wall of the roller 4214, so as to realize the limitation of the roller 4214 and fix the position of the device.

[0033] Furthermore, a plurality of card slots are circumferentially arranged on the side wall of the roller 4214. The inner diameter of the card slots is adapted to the outer wall of the other end of the plug post 4213. By arranging a plurality of card slots on the inner side wall of the roller 4214, it is convenient for the plug post 4213 to enter the inside of the card slots, so as to realize the limitation of the roller 4214 and thus realize the limitation of the device.

[0034] Furthermore, a push rod 2 is fixedly connected to the outer wall of the storage box 1. The top of the storage box 1 is movably connected to a box cover 3 through a hinge. A handle 5 is fixedly connected to the top of the box cover 3. By arranging the push rod 2 on the outer wall of the storage box 1, it is convenient for the operator to apply pressure to the push rod 2 and cooperate with the rotation of the roller 4214 to realize the transportation of the device. By arranging the box cover 3 on the top of the storage box 1, it is convenient for the operator to rotate the box cover 3 to make the box cover 3 on the top of the storage box 1 after the sample bottles are stored, so as to realize the preservation of the sample bottles.

[0035] In addition, there are three groups of F-shaped displacement blocks 4110. Each group of F-shaped displacement blocks 4110 has two, and every two F-shaped displacement blocks 4110 are staggered. By arranging three groups of F-shaped displacement blocks 4110, it is convenient to clamp and fix a plurality of sample bottles inside the storage box 1, thereby improving the stability of the device during the preservation of the sample bottles.

[0036] Working principle: When it is necessary to store the sample bottles after soil and water sampling, since the lengths of different types of sample bottles often vary, it is necessary to adjust the storage height of the sample bottles inside the storage box 1 according to the height of the sample bottles. At this time, the operator starts the first electric push rod 413 to make the first electric push rod 413 extend and push the lifting plate 414 to rise. When the height of the lifting plate 414 rises to a certain position, the operator places the sample bottle in the through groove 415 inside the lifting plate 414 so that the bottom of the sample bottle contacts the sponge block 412, thus preventing the sample bottle from being damaged by bumps during transportation;

[0037] After the sample bottle is placed inside the lifting plate 414, in order to improve the stability of the sample bottle during storage, it is necessary to clamp and fix the sample bottle. At this time, the operator starts the forward and reverse motor 417 to make the first rotating rod 418 rotate. After the first rotating rod 418 rotates, it will cause the butterfly-shaped rotating block 419 to rotate. During the rotation of the butterfly-shaped rotating block 419, its outer wall will squeeze the two F-shaped displacement blocks 4110. Due to the limiting effect of the set limiting block 4111 and limiting column 4112 on the F-shaped displacement blocks 4110, under the squeezing action of the butterfly-shaped rotating block 419 on the two F-shaped displacement blocks 4110, the two F-shaped displacement blocks 4110 will move alternately and approach each other, so that the inner sides of the two F-shaped displacement blocks 4110 squeeze the outer wall of the sample bottle, thus realizing the clamping of the sample bottle. In this process, it is convenient to clamp and fix sample bottles with different outer diameters, thereby improving the stability of the device when storing the sample bottles after soil and water sampling;

[0038] After the storage of the sample bottle is completed, when it is necessary to transport the device, it is easy to encounter uneven road surfaces. At this time, the roller 4214 will compress the connecting column 424 through the U-shaped block 425, so that the connecting column 424 squeezes the slider 423, and the slider 423 compresses the shock-absorbing spring 422. During the movement of the U-shaped block 425, it will cause the cross plate 426 to move. Under the action of the damper 427, it can cooperate with the shock-absorbing spring 422 to shock-absorb the device and improve the stability of the device during transportation;

[0039] When the cross plate 426 vibrates and moves, it will drive the connecting plate 428 to move and cooperate with the rotating plate 4220 to rotate, so that the rotating plate 4220 pushes the moving block 4218 to move along the outer wall of the cross column 4217, compress the return spring 4219, and cooperate with the shock-absorbing spring 422 and the damper 427 to further achieve the purpose of shock-absorbing the device;

[0040] When it is necessary to limit the roller 4214 after the transfer of the device is completed, the operator starts the drive motor 4210 to cause the lead screw 4211 to rotate. During the rotation of the lead screw 4211, the socket block 4212 will be prompted to move along the outer wall of the lead screw 4211 and push the plug post 4213 to move. After the plug post 4213 enters the embedding groove on the side wall of the U-shaped block 425, it then enters the inner wall of the side of the roller 4214, thereby realizing the limitation of the roller 4214 and fixing the position of the device.

[0041] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be selected and used alone according to actual needs or multiple features can be combined for use. Therefore, the present invention should logically cover other combinations and specific applications related to this case.
