Technical Field
[0001] This utility model relates to the technical field of water sample collection equipment, specifically a water quality data collection and analysis device. Background Technology
[0002] Water sampling and testing is a crucial part of environmental monitoring and water quality management. It aims to collect and analyze water samples using scientific methods to assess water quality, pollution sources, pollution levels, and trends.
[0003] In existing water sampling technologies, especially for sampling in deeper waters, there are often problems such as inaccurate positioning and difficulty in accurately controlling the sampling depth. Traditional sampling methods usually rely on manual operation or simple mechanical devices. When faced with complex and ever-changing aquatic environments, these methods often cannot ensure the accuracy and representativeness of the sampling, especially when sampling at a fixed depth or taking multiple samples at different depths, which is quite difficult.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a water quality data acquisition and analysis device to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a water quality data acquisition and analysis device, including a scissor lift, a first fixing rod, a guide rod, and a limiting rod. Several fixing blocks are rotatably connected to one side wall of the scissor lift along its extension direction, and all fixing blocks are sleeved on the outside of the same guide rod. Several shells are rotatably connected to the side wall of the scissor lift away from the fixing blocks, and all shells are sleeved at the center of the top of the end of each shell away from the scissor lift. The limiting rod's axial direction is parallel to the extension direction of the scissor lift. The shell is a hollow structure, and an external toothed ring rotatably connects to the bottom of the shell. Several second fixing rods arranged in a ring array are rotatably connected to the top of the external toothed ring. A limiting plate rotatably connects to the end of the second fixing rod away from the external toothed ring, and the limiting plate is located inside the external toothed ring. A gear is meshed with the outer end of the external toothed ring near the limiting rod, and the gear is sleeved on the outside of the limiting rod.
[0007] Furthermore, both ends of the guide rod are fixedly connected to the same fixing rod 1. The end of fixing rod 1 away from the guide rod is fixedly connected to the limiting rod. A channel 1 is opened at the top of the housing corresponding to the axis of the outer toothed ring. The channel 1 extends through the housing along the extension direction of the scissor lift. The outer toothed ring and the channel are coaxially arranged. A channel 2 is opened at the top of the housing corresponding to the axis of the limiting rod. The channel 2 extends through the housing along the extension direction of the scissor lift. The limiting rod slides in the channel 2. A collection container is detachably connected to the bottom opening of the channel 1.
[0008] Furthermore, the outer arc wall of the limiting rod is provided with a sliding groove 1 with the same structure on both the side wall near the scissor lift and the side wall away from the scissor lift. The length direction of the sliding groove 1 is consistent with the axial direction of the limiting rod and is provided through the end of the limiting rod. The outer arc wall of the limiting rod is provided with a plurality of sliding grooves 3, and the plurality of sliding grooves 3 correspond one-to-one with the plurality of housings. The sliding grooves 3 are spiral and coaxial with the limiting rod. The sliding grooves 3 and 1 are interconnected, and the two ends of the sliding grooves 3 are provided with sliding grooves 2 along the opposite sides. The sliding grooves 2 and 3 are interconnected, and the widths of the sliding grooves 2 and 3 are the same. The width of the sliding groove 3 is smaller than the width of the sliding groove 1.
[0009] Furthermore, a wedge block is fixedly connected to one end of the slide groove two away from the slide groove three. The inclined surface of the wedge block is connected to the inner wall of the slide groove one and the slide groove three respectively. The width of several slide grooves two and three increases sequentially along the extension direction of the scissor lift. A guide post slides in the slide groove one. The guide post is movably connected to the inner arc wall of the gear. The cross-sectional radius of several guide posts increases sequentially along the extension direction of the scissor lift, and the increasing direction of the guide posts is consistent with that of the slide groove three.
[0010] Furthermore, a storage groove is provided radially on the inner arc wall of the gear, and a guide post slides in the storage groove. A reset spring is fixedly connected to the end of the guide post away from the gear axis, and the end of the reset spring away from the guide post is fixedly connected to the inner wall of the storage groove.
[0011] Furthermore, a horizontally arranged fixed shaft is fixedly connected to one end of the outer wall of the housing near the scissor lift. The fixed shaft passes through the housing and is rotatably connected to the housing. The end of the fixed shaft away from the housing is fixedly connected to a fixed block. A locking block is fixedly connected to the end of the fixed shaft away from the housing. A limiting slot adapted to the locking block is provided on the outer wall of the fixed block near the fixed shaft. The locking block is inserted into the limiting slot.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The scissor lift mechanism drives multiple sampling containers to descend. As they descend, the position of the sliding groove three on the limit rod determines when the closure of channel one on the shell will be released, thus enabling multi-point sampling at different depths. Furthermore, the length of the scissor lift extension can be calculated by the rotation angle of the scissor lift, allowing for convenient understanding of the current sampling depth. In addition, the mesh structure of the scissor lift reduces the contact area with the water flow, thereby reducing the impact of the water flow and ensuring the accuracy of the detection.
[0014] 2. All components in the device are detachable and replaceable, facilitating daily maintenance and upkeep. At the same time, the detachable design of components such as the collection container also facilitates the collection and treatment of water samples. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see the appendix Figure 1 To be continued Figure 6This utility model provides a water quality data acquisition and analysis device, comprising a scissor lift 10, a fixing rod 11, a guide rod 12, and a limiting rod 13. A plurality of fixing blocks 14, evenly distributed along the extension direction of the scissor lift 10, are rotatably connected to one side wall of the scissor lift 10. All fixing blocks 14 are sleeved on the outside of the same guide rod 12. A plurality of housings 20, evenly distributed along the extension direction of the scissor lift 10, are rotatably connected to the side wall of the scissor lift 10 away from the fixing blocks 14. The housings 20 are located away from the scissor lift. The same limiting rod 13 is sleeved at the center of the top of one end of the scissor lift 10. The axial direction of the limiting rod 13 is parallel to the extension direction of the scissor lift 10. The housing 20 is a hollow structure. An external toothed ring 21 is rotatably connected to the bottom of the housing 20. Several fixed rods 22 arranged in a ring array are rotatably connected to the top of the external toothed ring 21. A limiting plate 23 is rotatably connected to the end of the fixed rod 22 away from the external toothed ring 21. The limiting plate 23 is located inside the external toothed ring 21. A gear 24 is meshed with the end of the external toothed ring 21 near the limiting rod 13. The gear 24 is sleeved on the outside of the limiting rod 13.
[0028] It should be noted that when the scissor lift 10 moves along the guide rod 12, the scissor lift 10 can maintain a stable telescopic trajectory due to the sleeve relationship between the fixed block 14 and the guide rod 12. At the same time, the housing 20 moves up and down with the telescopic movement of the scissor lift 10, and the guide rod 12 and the limiting rod 13 work together to maintain stability during the movement.
[0029] The scissor lift 10 includes several sets of scissor arms. Each set of scissor arms includes two scissor arms, namely scissor arm 1 and scissor arm 2, which are rotatably connected to each other. Scissor arms 1 and scissor arms 2 in the same set are stacked on top of each other and are rotatably connected to each other through the same connecting shaft 1 in the middle. Scissor arms 1 and scissor arms 2 in adjacent sets of scissor arms are rotatably connected to each other through the same connecting shaft 2. Thus, multiple sets of scissor arms are rotatably connected to each other to form a mesh structure.
[0030] The scissor arms 1 and 2, which are closer to the fixed rod 11, are longer, making it easier for operators to operate. The fixed block 14, which is closer to the fixed rod 11, is fixedly connected to the outer arc wall of the guide rod 12. That is, the fixed block 14 serves as the fulcrum for the telescopic and folding of the scissor frame 10.
[0031] The limiting plate 23 is crescent-shaped, and its top center is rotatably connected to the second fixing rod 22. One end of the limiting plate 23 away from the second fixing rod 22 rotates on the bottom inner wall of the housing 20. When several limiting plates 23 abut against each other, they can completely block the first channel. Furthermore, the side walls of the limiting plates 23 that are close to each other are provided with sealing gaskets.
[0032] Please see the appendix Figure 1 To be continued Figure 6This utility model provides a technical solution: both ends of the guide rod 12 are fixedly connected to the same fixing rod 11. The end of the fixing rod 11 away from the guide rod 12 is fixedly connected to the limiting rod 13. A channel 1 is opened at the top of the housing 20 corresponding to the axis of the external toothed ring 21. The channel 1 extends through the housing 20 along the extension direction of the scissor lift 10. The external toothed ring 21 is coaxial with the channel. A second channel is opened at the top of the housing 20 corresponding to the axis of the limiting rod 13. The second channel extends through the housing 20 along the extension direction of the scissor lift 10. The limiting rod 13 slides in the second channel. A collection container 26 is detachably connected to the bottom opening of the first channel.
[0033] It should be noted that: Channel 1 is the opening through which water flows into the collection container 26, and Channel 2 is the opening through which the limiting rod 13 passes.
[0034] Please see the appendix Figure 1 To be continued Figure 6 This utility model provides a technical solution: the outer arc wall of the limiting rod 13 is provided with a sliding groove 30 with the same structure on the side wall near the scissor lift 10 and the side wall away from the scissor lift 10. The length direction of the sliding groove 30 is consistent with the axial direction of the limiting rod 13 and is provided through the end of the limiting rod 13. The outer arc wall of the limiting rod 13 is provided with a plurality of sliding grooves 32, and the plurality of sliding grooves 32 correspond one-to-one with the plurality of housings 20. The sliding grooves 32 are spiral and coaxial with the limiting rod 13. The sliding grooves 32 and the sliding grooves 30 are interconnected. The two ends of the sliding grooves 32 are provided with sliding grooves 31 on the side away from each other. The sliding grooves 31 and the sliding grooves 32 are interconnected. The width of the sliding grooves 31 and the sliding grooves 32 is the same. The width of the sliding grooves 32 is smaller than the width of the sliding grooves 30.
[0035] It should be noted that: the slide groove 32 is spiral and is interconnected with the slide groove 30. The position of the slide groove 32 determines where the gear 24 will rotate, thereby opening the channel 1. The pitch of the slide groove 32 determines the rotational speed of the gear 24.
[0036] Please see the appendix Figure 1 To be continued Figure 6 The present invention provides a technical solution: a wedge block is fixedly connected to one end of the slide groove 31 away from the slide groove 32. The inclined surface of the wedge block is connected to the inner wall of the slide groove 30 and the slide groove 32 respectively. The width of the slide groove 31 and the slide groove 32 increases sequentially along the extension direction of the scissor lift 10. A guide post 25 slides in the slide groove 30. The guide post 25 is movably connected to the inner arc wall of the gear 24. The cross-sectional radius of the guide post 25 increases sequentially along the extension direction of the scissor lift 10, and the increasing direction of the guide post 25 is consistent with that of the slide groove 32.
[0037] A storage groove is provided on the inner arc wall of the gear 24 along its radial direction. A guide post 25 slides in the storage groove. A reset spring is fixedly connected to the end of the guide post 25 away from the axis of the gear 24. The end of the reset spring away from the guide post 25 is fixedly connected to the inner wall of the storage groove.
[0038] It should be noted that: the guide post 25 initially slides in the slide groove 30. When the cross-sectional radius of the guide post 25 is smaller than the cross-sectional radius of the slide groove 31, the guide post 25 will pop out and get stuck in the slide groove 31 under the action of the reset spring, and then enter the slide groove 32. At this time, the guide post 25 will be guided by the slide groove 32 to rotate around the limit rod 13, which will drive the gear 24 to rotate, and then drive the corresponding channel 1 to open.
[0039] Furthermore, the width of the groove 32 at the end of the limiting rod 13 furthest from the fixed rod 11 is the largest, and the cross-sectional radius of the guide post 25 at the end furthest from the fixed rod 11 is the largest. Therefore, the guide post 25 at the end furthest from the fixed rod 11 will not be stuck when it passes through the groove 32 at the end closest to the fixed rod 11.
[0040] Please see the appendix Figure 1 To be continued Figure 6 The present invention provides a technical solution: a horizontally arranged fixed shaft 15 is fixedly connected to one end of the outer wall of the housing 20 near the scissor lift 10. The fixed shaft 15 passes through the housing 20 and is rotatably connected to the housing 20. The end of the fixed shaft 15 away from the housing 20 is fixedly connected to the fixed block 14. A locking block 16 is fixedly connected to the end of the fixed shaft 15 away from the housing 20. A limiting slot adapted to the locking block 16 is provided on the outer wall of the fixed block 14 near the fixed shaft 15. The locking block 16 is inserted into the limiting slot.
[0041] It should be noted that: the fixed shaft 15 is set through the damping shaft, and the locking block 16 and the limiting slot are used to strengthen the connection between the fixed block 14 and the housing 20, and at the same time facilitate disassembly.
[0042] Working principle:
[0043] The guide post 25 initially slides within the first slide groove 30. When the cross-sectional radius of the guide post 25 is smaller than that of the second slide groove 31, the guide post 25 will pop out and be inserted into the second slide groove 31 under the action of the reset spring, and then enter the third slide groove 32. At this time, the guide post 25 will be guided by the third slide groove 32 to rotate around the limiting rod 13, which will drive the gear 24 to rotate, and then drive the corresponding gear 24 to rotate. The gear 24 meshes with the outer toothed ring 21, which will drive the limiting plate 23 to open the first channel. At this time, water will enter the collection container 26. The reverse drive of the scissor lift 10 can make the multiple housings 20 move in the opposite direction. At the same time, the gear 24 rotates in the opposite direction to close the first channel.
[0044] Furthermore, the width of the groove 32 at the end of the limiting rod 13 furthest from the fixed rod 11 is the largest, and the cross-sectional radius of the guide post 25 at the end furthest from the fixed rod 11 is the largest. Therefore, the guide post 25 at the end furthest from the fixed rod 11 will not be stuck when it passes through the groove 32 at the end closest to the fixed rod 11.
