Description

Technical Field

[0001] This utility model relates to the field of water quality testing sampler technology, specifically to a stratified sampler for water quality testing. Background Technology

[0002] In the field of water quality testing, understanding the distribution of microorganisms in water bodies is crucial. This not only helps assess the health of water bodies but also provides a scientific basis for environmental protection and water resource management. Patent CN202422331824.9 discloses a stratified sampler for water quality testing. Through a combination design of a mounting frame, sampling mechanism, and support frame, multiple water layers can be sampled at once with a simple pressing action, reducing the need for repeated sampler placement and adjustments, lowering operational difficulty and labor intensity, and improving work efficiency. However, during the use of the stratified sampler, operators need to manually press the pressing disc to release the blocked sampling port, which is quite inconvenient when sampling deeper water sources. Therefore, we propose a stratified sampler for water quality testing. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a stratified sampler for water quality testing.

[0004] The technical solution adopted by this utility model to solve its technical problem is a stratified sampler for water quality testing, including a plate frame. The inner side of the plate frame is equipped with tube seats for support by bolts, and there are multiple sets of tube seats. The bottom surface of the tube seat is screwed with a ring shell for sealing, and the inner side of the ring shell is slidably installed with a sliding sleeve that fits with the tube seat. The outer circumference of the sliding sleeve is clamped with a rubber sleeve for leak prevention, and a vertical cylinder that is slidably connected to both the ring shell and the tube seat is assembled between the multiple sets of sliding sleeves. The top surface of the plate frame is equipped with an electric push rod for driving the vertical cylinder to slide displacement by bolts. The outer wall surface of the plate frame and the outer wall surface of the tube seat are both provided with interconnected straight holes, and there are multiple sets of straight holes. The outer wall surface of the plate frame is screwed with a bent tube that communicates with the straight holes, and the end of the bent tube away from the plate frame is screwed with a sampling bottle for sampling.

[0005] The outer wall surface of the plate frame is integrally constructed with a protective box, and the inner side of the box is equipped with a battery pack electrically connected to the electric push rod. The outer wall surface of the plate frame is equipped with a controller electrically connected to the electric push rod, and the top surface of the box is provided with a remote interactive device electrically connected to the controller. Multiple sets of lifting rings are rotatably installed on the top surface of the plate frame.

[0006] By adopting the above technical solution, during the use of the water quality testing stratified sampler, the plate frame is placed in the water source, and the electric push rod at the top of the plate frame can operate to easily push the vertical cylinder inside the plate frame. This allows the vertical cylinder to simultaneously drive the sliding sleeves inside multiple sets of tube seats to move. At the same time, the sliding sleeves drive the rubber sleeves to move and release the blocked holes on the outer periphery of the tube seats, allowing the external water source to enter the tube seat and easily pass through the straight holes and bends to enter the sampling bottle. The electric operation is more convenient, and the design of multiple sampling bottles facilitates sampling of different water layers inside the water source. After sampling, the electric push rod can continue to operate and easily drive the sliding sleeves back to their original position through the vertical cylinder, which can then drive the rubber sleeves to continue sealing the holes on the outer periphery of the tube seats and the straight holes, thus facilitating smooth sampling.

[0007] During the use of the water quality testing sampler, the lifting rings on the plate frame surface facilitate hoisting, enabling the sampler to sample water sources at different depths. During the sampling process, the battery pack inside the box provides power to the electric push rod, while the remote control allows for remote control and operation of the electric push rod via the controller. This ensures that the sampler can successfully collect water samples, facilitating subsequent testing.

[0008] Specifically, the outer wall surface of the box is fitted with a cover plate for sealing by screws, and the top surface of the plate frame is fitted with a shell cover located on the outer periphery of the electric push rod by bolts.

[0009] By adopting the above technical solution, the cover is located on the outer periphery of the electric push rod on the outer periphery of the plate frame and facilitates the protection of the electric push rod, enabling the electric push rod to operate more stably. The cover plate on the outside of the box is easy to disassemble and install, making it convenient to maintain the internal structure of the box.

[0010] Specifically, a rubber ring that fits into the annular shell is provided on the bottom surface of the tube seat.

[0011] By adopting the above technical solution, the rubber ring can improve the tightness of the screw connection between the ring shell and the tube seat.

[0012] Specifically, a protective filter plate is fitted inside the outer peripheral opening of the tube seat by screws.

[0013] By adopting the above technical solution, the filter screen plate can easily protect the opening on the outer periphery of the tube seat, thus reducing the possibility of garbage and debris entering the tube seat.

[0014] Specifically, the inner side of the plate frame is equipped with a vertical rod that is inserted and connected to the vertical cylinder, and compression springs for buffering are installed between the plate frame and the vertical cylinder and between the ring shell and the sliding sleeve.

[0015] By adopting the above technical solution, the compression spring inside the ring shell can buffer the displacement of the sliding sleeve, so that the sliding sleeve can move more stably with the displacement of the vertical cylinder. The vertical rod inside the plate frame is interlocked and slidably connected with the vertical cylinder, which can improve the stability of the vertical cylinder during lifting and sliding displacement. The compression spring inside the plate frame located on the outer periphery of the vertical rod can buffer the lifting and sliding displacement of the vertical cylinder, so that the vertical cylinder can lift and slide more stably.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of an electric push rod, vertical cylinder, tube seat, ring shell, sliding sleeve, rubber sleeve, straight hole, bent pipe, and sampling bottle, allows for the use of a water quality testing stratified sampler. When the plate frame is placed in the water source, the electric push rod at the top of the plate frame operates, easily pushing the vertical cylinder inside the plate frame. This allows the vertical cylinder to simultaneously move the sliding sleeves inside multiple tube seats. Simultaneously, the sliding sleeves move the rubber sleeves, releasing the blocked holes on the outer periphery of the tube seats. This allows external water to enter the tube seats and easily pass through the straight hole, guided by the bent pipe, into the sampling bottle. The electric operation is more convenient, and the multiple sampling bottle design facilitates sampling from different water layers within the water source. After sampling, the electric push rod continues to operate, easily moving the sliding sleeve back to its original position via the vertical cylinder. This allows the rubber sleeve to continue sealing the holes on the outer periphery of the tube seats and the straight hole, thus facilitating smooth sampling.

[0018] 2. The technical solution of this application, through the design of the housing, battery pack, controller, remote intercom, and lifting ring, facilitates the hoisting of the water quality testing sampler during use. The lifting ring on the surface of the frame allows the sampler to sample water sources at different depths. During the sampling process, the battery pack inside the housing provides power to the electric push rod, and the remote intercom allows for remote control and operation of the electric push rod via the controller. This enables the sampler to successfully collect water samples, facilitating subsequent testing. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a stratified sampler for water quality testing, comprising a plate frame 1, with multiple sets of tube seats 2 bolted to the inner side of the plate frame 1 for support, and an annular shell 3 for sealing screwed onto the bottom surface of the tube seat 2, and a sliding sleeve 4 that fits into the tube seat 2 slidably mounted on the inner side of the annular shell 3, with a leak-proof rubber sleeve 5 snapped onto the outer circumference of the sliding sleeve 4, and a vertical cylinder 7 slidably connected to both the annular shell 3 and the tube seat 2 assembled between the multiple sets of sliding sleeves 4, and an electric push rod 8 for driving the vertical cylinder 7 to slide displacement bolted to the top surface of the plate frame 1, and both the outer wall surface of the plate frame 1 and the outer wall surface of the tube seat 2 are provided with... There are interconnected straight holes 9, and there are multiple sets of straight holes 9. A bent pipe 10 connected to the straight holes 9 is screwed onto the outer wall surface of the plate frame 1, and a sampling bottle 11 for sampling is screwed onto the end of the bent pipe 10 away from the plate frame 1. A protective box 13 is integrally constructed on the outer wall surface of the plate frame 1, and a battery pack 14 electrically connected to the electric push rod 8 is assembled inside the box 13. A controller 17 electrically connected to the electric push rod 8 is assembled on the outer wall surface of the plate frame 1, and a remote interactive device 16 electrically connected to the controller 17 is provided on the top surface of the box 13. A lifting ring 18 is rotatably mounted on the top surface of the plate frame 1, and there are multiple sets of lifting rings 18.

[0026] When using the water quality testing stratified sampler, the plate frame 1 is placed into the water source, and the electric push rod 8 at the top of the plate frame 1 operates, which facilitates the pushing of the vertical cylinder 7 inside the plate frame 1. This allows the vertical cylinder 7 to simultaneously drive the sliding sleeves 4 inside multiple sets of tube seats 2 to move. At the same time, the sliding sleeves 4 drive the rubber sleeves 5 to move and release the blocked holes on the outer periphery of the tube seats 2, allowing the external water source to enter the tube seat 2 and easily pass through the straight hole 9 and bend 10 to enter the sampling bottle 11. The electric operation is more convenient, and the design of multiple sampling bottles 11 facilitates sampling of different water layers inside the water source. After sampling, the electric push rod 8 continues to operate and the vertical cylinder 7 drives the sliding sleeve 4 to return to its original position, which facilitates the rubber sleeves 5 to continue blocking the holes on the outer periphery of the tube seats 2 and the straight hole 9, thus facilitating smooth sampling.

[0027] During the use of the water quality testing sampler, the lifting ring 18 on the surface of the plate frame 1 facilitates hoisting, enabling the sampler to sample water sources at different depths. During the sampling process, the battery pack 14 inside the housing 13 provides power to the electric push rod 8, while the remote control 16 facilitates remote control and allows the electric push rod 8 to operate via the controller 17. This ensures that the sampler can successfully sample the water quality, facilitating subsequent testing.

[0028] like Figure 1 and Figure 3 As shown, a cover plate 15 for sealing is installed on the outer wall surface of the box body 13 by screws, and a housing 19 located on the outer periphery of the electric push rod 8 is installed on the top surface of the plate frame 1 by bolts.

[0029] During use, the cover 19 is located on the outer periphery of the electric push rod 8 on the outer periphery of the plate frame 1 and provides convenient protection for the electric push rod 8, enabling the electric push rod 8 to operate more stably. The cover plate 15 on the outer side of the box 13 is easy to disassemble and install, facilitating the maintenance of the internal structure of the box 13.

[0030] like Figure 1 and Figure 2 As shown, a rubber ring 12 that fits into the ring shell 3 is provided on the bottom surface of the tube seat 2.

[0031] When in use, the rubber ring 12 helps to improve the tightness of the screw connection between the ring shell 3 and the tube seat 2.

[0032] like Figure 1 and Figure 2 As shown, a filter screen 6 for protection is installed on the inner side of the outer opening end of the tube seat 2 by screws.

[0033] When in use, the filter plate 6 can protect the opening on the outer periphery of the tube seat 2, which helps to reduce the entry of garbage and debris into the tube seat 2.

[0034] like Figure 1 and Figure 2 As shown, the inner side of the plate frame 1 is equipped with a vertical rod 20 that is connected to the vertical cylinder 7 by insertion, and compression springs 21 for buffering are installed between the plate frame 1 and the vertical cylinder 7 and between the ring shell 3 and the sliding sleeve 4.

[0035] During use, the compression spring 21 inside the ring shell 3 facilitates the buffering of the displacement of the sliding sleeve 4, allowing the sliding sleeve 4 to move more stably with the displacement of the vertical cylinder 7. The vertical rod 20 inside the plate frame 1 is interlocked with and slidably connected to the vertical cylinder 7, which facilitates the improvement of the stability of the vertical cylinder 7 during lifting and sliding displacement. The compression spring 21 located on the outer periphery of the vertical rod 20 inside the plate frame 1 facilitates the buffering of the lifting and sliding displacement of the vertical cylinder 7, allowing the vertical cylinder 7 to lift and slide more stably.

[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in appropriate positions. During the use of the water quality testing stratified sampler, place the plate frame 1 into the water source, enabling the electric push rod 8 at the top of the plate frame 1 to operate and easily push the vertical cylinder 7 inside the plate frame 1. This allows the vertical cylinder 7 to simultaneously drive the sliding sleeves 4 inside multiple sets of tube seats 2 to move. Simultaneously, the sliding sleeves 4 drive the rubber sleeves 5 to move, releasing the blocked holes on the outer periphery of the tube seats 2. This allows external water to enter the tube seats 2 and easily pass through the straight hole 9, guided by the bent pipe 10, into the sampling bottle 11. The electric operation is more convenient, and the design of multiple sampling bottles 11 facilitates sampling different water layers within the water source. The sampler is designed to facilitate sampling by allowing the electric push rod 8 to continue operating after sampling and to easily return the sliding sleeve 4 to its original position via the vertical cylinder 7. This facilitates the sealing of the holes on the outer periphery of the tube seat 2 by the rubber sleeve 5 and the sealing of the straight hole 9. This ensures smooth sampling. During the use of the water quality testing sampler, the lifting ring 18 on the surface of the plate frame 1 facilitates hoisting, allowing the sampler to sample water sources at different depths. During the sampling process, the battery pack 14 inside the box 13 provides power to the electric push rod 8, while the remote control 16 allows for remote control and the operation of the electric push rod 8 via the controller 17. This ensures that the sampler can successfully sample water quality for subsequent testing.
