Description

A sample storage device for water quality environmental testing Technical Field

[0001] This utility model belongs to the technical field of sample storage devices for water quality environmental testing, and particularly relates to a sample storage device for water quality environmental testing. Background Technology

[0002] Water quality environmental testing, also known as water quality analysis, refers to the process of monitoring and analyzing physical, chemical, and biological indicators in water bodies to assess water quality. Water quality environmental testing sample storage devices are instruments used for collecting, preserving, and transporting water samples. In summary, the existing technology has the following problems: Water samplers are a type of water quality environmental testing sample storage device. When in use, the water sampler is placed in the water and removed when full. Water quality at different depths may vary significantly, so sampling at different depths is necessary. However, the water sampler itself is lightweight and cannot be accurately moved to a specific depth in the water. A sampler without adjustable weight may only collect surface or fixed-depth water samples, failing to obtain complete vertical water quality information. However, existing water quality samplers used for water quality environmental testing lack weight adjustment components for different water depths. Therefore, a water quality environmental testing sample storage device is proposed to solve these problems. Summary of the Invention

[0003] To address the problems of existing technologies, this utility model provides a sample storage device for water quality environmental testing. This device allows for weight adjustment of the water sampler used in water quality environmental testing according to different water depths. It solves the problem that existing water samplers, which are simply placed in water and removed when full, cannot accurately reach specific depths due to the significant differences in water quality at different depths. Furthermore, the lightweight nature of existing water samplers may limit their movement to surface or fixed depth samples, failing to obtain complete vertical water quality information. Finally, existing water samplers for water quality environmental testing lack a weight adjustment mechanism for different water depths.

[0004] This utility model is implemented as follows: a sample storage device for water quality environmental testing includes a water sampler and a counterweight base. The bottom of the water sampler is fixedly connected to the top of the counterweight base. A plurality of counterweight rings are movably connected to the inner cavity of the counterweight base. A circular pressure shell is movably connected to the surface of the counterweight base. The bottom of the circular pressure shell contacts the top of the counterweight rings. A fixing device is provided in the inner cavity of the circular pressure shell.

[0005] As a preferred embodiment of this utility model, the fixing device includes four fixing plates, each with a limiting groove inside. A spring is fixedly connected to the surface of the fixing plate, and the surface of the spring is fixedly connected to the inner cavity of the circular pressure shell. By setting the fixing device, when the circular pressure shell moves to an appropriate position, the fixing device has a limiting effect on the position of the circular pressure shell.

[0006] As a preferred embodiment of this utility model, the inner cavity of the circular pressure shell is fixedly connected with four limiting frames that cooperate with the limiting groove. The surface of the limiting frame contacts the inner cavity of the limiting groove. The side of the limiting frame near the spring passes through the fixing plate. By setting the limiting frame, when the fixing plate moves, it will drive the limiting groove to move along the surface of the limiting frame. The cooperation between the limiting frame and the limiting groove has a limiting effect on the movement position of the fixing plate.

[0007] In a preferred embodiment of this invention, a rotating column is fixedly connected to the top of the fixed plate, and a four-sided arc frame that cooperates with the rotating column is movably connected to the inner cavity of the circular pressure shell. The surface of the four-sided arc frame contacts the surface of the rotating column, and the top of the four-sided arc frame penetrates through the circular pressure shell and extends to the outer side of the inner cavity of the circular pressure shell. By setting the rotating column and the four-sided arc frame, when the four-sided arc frame rotates, it can generate a squeezing force on the rotating column, and the rotating column subjected to the squeezing force can drive the fixed plate to move.

[0008] In a preferred embodiment of this invention, a control turntable is fixedly connected to the top of the quadrilateral arc frame, and two control blocks that cooperate with the control turntable are fixedly connected to the top of the circular pressure shell. The surface of the control blocks is movably connected to the inner cavity of the control turntable. By setting the control blocks and the control turntable, when the control turntable rotates along the surface of the control blocks, it can drive the quadrilateral arc frame to rotate along the surface of the rotating column. The cooperation between the control turntable and the control blocks has a limiting effect on the rotation position of the quadrilateral arc frame.

[0009] As a preferred embodiment of this utility model, the inner cavity of the counterweight base is provided with a locking plate groove for use with a fixing block. The surface of the fixing block contacts the inner cavity of the locking plate groove. There are several locking plate grooves, which are evenly distributed in the inner cavity of the counterweight base. By setting the locking plate grooves, when the circular pressure shell moves to the position of contacting the surface of the counterweight ring, the control turntable is released. The restoring force generated by the spring returning to its shape will drive the fixing plate to be locked into the inner cavity of the locking plate groove. The cooperation between the fixing plate and the locking plate groove has a limiting effect on the position of the circular pressure shell.

[0010] As a preferred embodiment of this utility model, a positioning post is fixedly connected to the bottom of the inner cavity of the counterweight base for use with the counterweight ring. The surface of the positioning post is in contact with the inner cavity of the counterweight ring and the surface of the positioning post is in contact with the inner cavity of the circular pressure shell. By setting the positioning post, when the counterweight ring is sleeved on the positioning post, the cooperation between the positioning post and the circular pressure shell has a limiting effect on the position of the counterweight ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing water quality samplers, which are a type of sample storage device for water quality environmental testing, by setting up a fixing device, fixing plate, limiting groove, and spring in combination. The water quality of water bodies at different depths may vary significantly, so it is necessary to sample water bodies at different depths. However, the water quality sampler itself is relatively light and cannot be accurately moved to a specific depth in the water body. The sampler, which cannot adjust its weight, may only collect water samples from the surface or a certain fixed depth, and cannot obtain complete vertical water quality information. However, the existing water quality samplers used for water quality environmental testing do not have a component for adjusting the weight according to different water depths.

[0013] 2. By setting a fixing device, the rotating column, which is subjected to the squeezing force of the four-sided arc frame, will drive the fixing plate to move closer to the inner cavity of the circular pressure shell. When the fixing plate moves, it will drive the limiting groove to move along the surface of the limiting frame. At the same time, the force generated when the fixing plate moves will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the fixing plate to be inserted into the inner cavity of the plate groove. The fixing device has a limiting effect on the position of the circular pressure shell. Attached Figure Description

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] As shown in Figures 1 to 4, the present invention provides a sample storage device for water quality environmental testing, including a water sampler 1 and a counterweight base 2. The bottom of the water sampler 1 is fixedly connected to the top of the counterweight base 2. A plurality of counterweight rings 3 are movably connected to the inner cavity of the counterweight base 2. A circular pressure shell 4 is movably connected to the surface of the counterweight base 2. The bottom of the circular pressure shell 4 contacts the top of the counterweight rings 3. A fixing device 5 is provided in the inner cavity of the circular pressure shell 4.

[0022] Referring to Figure 4, the fixing device 5 includes four fixing plates 501. The fixing plates 501 have limit grooves 502 inside. Springs 503 are fixedly connected to the surface of the fixing plates 501. The surface of the springs 503 is fixedly connected to the inner cavity of the circular pressure shell 4.

[0023] The above solution is adopted: by setting the fixing device 5, when the circular pressure shell 4 moves to the appropriate position, the fixing device 5 has a limiting effect on the position of the circular pressure shell 4.

[0024] Referring to Figure 2, the inner cavity of the circular pressure shell 4 is fixedly connected with four limiting frames 6 that cooperate with the limiting groove 502. The surface of the limiting frame 6 is in contact with the inner cavity of the limiting groove 502, and the side of the limiting frame 6 near the spring 503 passes through the fixing plate 501.

[0025] The above solution is adopted: by setting the limiting frame 6, when the fixed plate 501 moves, it will drive the limiting groove 502 to move along the surface of the limiting frame 6. The cooperation of the limiting frame 6 and the limiting groove 502 has a limiting effect on the movement position of the fixed plate 501.

[0026] Referring to Figure 4, a rotating column 7 is fixedly connected to the top of the fixed plate 501, and a four-sided arc frame 8 that works with the rotating column 7 is movably connected to the inner cavity of the circular pressure shell 4. The surface of the four-sided arc frame 8 is in contact with the surface of the rotating column 7, and the top of the four-sided arc frame 8 penetrates through the circular pressure shell 4 and extends to the outside of the inner cavity of the circular pressure shell 4.

[0027] The above solution is adopted: by setting a rotating column 7 and a four-sided arc frame 8, when the four-sided arc frame 8 rotates, it can generate a squeezing force on the rotating column 7, and the rotating column 7 subjected to the squeezing force can drive the fixed plate 501 to move.

[0028] Referring to Figure 3, a control turntable 9 is fixedly connected to the top of the four-sided arc frame 8, and two control blocks 10 that cooperate with the control turntable 9 are fixedly connected to the top of the circular pressure shell 4. The surface of the control blocks 10 is movably connected to the inner cavity of the control turntable 9.

[0029] The above scheme is adopted: by setting up control card block 10 and control turntable 9, when control turntable 9 rotates along the surface of control card block 10, it can drive the four-sided arc frame 8 to rotate along the surface of rotating column 7. The cooperation between control turntable 9 and control card block 10 has a limiting effect on the rotation position of the four-sided arc frame 8.

[0030] Referring to Figure 2, the inner cavity of the counterweight base 2 is provided with a card slot 11 for use with the fixing block. The surface of the fixing block is in contact with the inner cavity of the card slot 11. There are several card slots 11 and they are evenly distributed in the inner cavity of the counterweight base 2.

[0031] The above scheme is adopted: by setting the card slot 11, when the circular pressure shell 4 moves to the position of contact with the surface of the counterweight ring 3, the control turntable 9 is released, and the restoring force generated by the spring 503 returning to its shape will drive the fixed card 501 to be inserted into the inner cavity of the card slot 11. The cooperation of the fixed card 501 and the card slot 11 has a limiting effect on the position of the circular pressure shell 4.

[0032] Referring to Figure 2, a positioning post 12 that works with the counterweight ring 3 is fixedly connected to the bottom of the inner cavity of the counterweight base 2. The surface of the positioning post 12 is in contact with the inner cavity of the counterweight ring 3, and the surface of the positioning post 12 is in contact with the inner cavity of the circular pressure shell 4.

[0033] The above scheme is adopted: by setting the positioning post 12, when the counterweight ring 3 is sleeved on the positioning post 12, the cooperation between the positioning post 12 and the circular pressure shell 4 has a limiting effect on the position of the counterweight ring 3.

[0034] The working principle of this utility model:

[0035] When using the water sampler 1 for water quality environmental testing, if the weight needs to be adjusted according to different water depths, the user first places an appropriate number of counterweight rings 3 on the surface of the positioning column 12. Then, the user rotates the control turntable 9, causing it to rotate along the surface of the control block 10. When the control turntable 9 rotates, it will cause the four-sided arc frame 8 to rotate along the surface of the rotating column 7. The rotating column 7, subjected to the squeezing force of the four-sided arc frame 8, will cause the fixed plate 501 to move closer to the inner cavity of the circular pressure shell 4. When the fixed plate 501 moves, it will cause the limiting groove 502 to move along the surface of the limiting frame 6. At the same time, the force generated when the fixed plate 501 moves causes the spring 503 to spring back. When the fixed plate 501 moves completely into the inner cavity of the circular pressure shell 4, it pulls the circular pressure shell 4 towards the side closer to the counterweight ring 3, causing the circular pressure shell 4 to move along the surface of the counterweight base 2. When the bottom of the circular pressure shell 4 contacts the top of the counterweight ring 3, the control turntable 9 is released. The restoring force generated by the spring 503 returning to its shape will cause the fixed plate 501 to be inserted into the inner cavity of the plate slot 11. The cooperation between the fixed plate 501 and the plate slot 11 restricts the position of the circular pressure shell 4. The cooperation between the positioning column 12 and the circular pressure shell 4 restricts the position of the counterweight ring 3. At this time, the water quality sampler 1 used for water quality environmental testing adjusts its weight according to the water depth.

[0036] In summary, this water quality environmental testing sample storage device, through the coordinated use of the fixing device 5, fixing plate 501, limiting groove 502, and spring 503, solves the problem that existing water quality samplers, which are a type of water quality environmental testing sample storage device, can only be placed in water and removed when full. However, water quality conditions at different depths may vary significantly, necessitating sampling at different depths. Furthermore, the water quality sampler itself is relatively lightweight and cannot accurately move to a specific depth in the water. A sampler without adjustable weight may only collect surface or fixed-depth water samples, failing to obtain complete vertical water quality information. Existing water quality environmental testing samplers lack components for weight adjustment based on water depth.
