Description
Technical Field
[0001] This utility model relates to the field of sampling devices, and in particular to a marine ecological environment detection sampling device. Background Technology
[0002] Against the backdrop of global marine ecological environment protection and sustainable development, marine ecological environment monitoring has become a crucial link in safeguarding marine resources. Marine ecological environment monitoring sampling devices, as core tools for acquiring key data on marine water quality, sediments, and organisms, directly impact the accuracy of monitoring results and operational efficiency. From nearshore shallows to deep-sea areas, from estuarine wetlands to open seas, diverse marine environments place high demands on the adaptability of sampling devices. Developing efficient, stable sampling devices adaptable to various scenarios has become an important direction for the development of marine environmental monitoring technology.
[0003] Existing marine ecological environment monitoring and sampling devices mostly adopt a fixed rigid frame structure in their mechanical design. The core sampling components and supporting structure are fixedly connected by bolts, welding, or pins, forming a non-adjustable overall length. Technically, these devices typically rely on manual lifting, robotic arm hoisting, or ship towing to reach the sampling point. They then use a pre-set sampling container or tool to complete the sampling at a fixed depth. Some devices are equipped with simple scale markings to assist in determining the sampling depth, but the overall length cannot be dynamically adjusted according to actual needs.
[0004] However, existing sampling devices, due to their fixed overall length, have significant limitations when facing sampling needs at different water depths. When sampling in shallow waters, excessively long devices are prone to getting stuck in mud or colliding with seabed obstacles; while in deeper waters, excessively short devices cannot reach the target sampling layer, forcing operators to frequently change devices of different specifications or use additional auxiliary tools. This seriously affects the convenience of sampling operations and reduces the device's adaptability to diverse marine sampling environments. Therefore, a marine ecological environment monitoring sampling device is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a marine ecological environment detection and sampling device, including a fixed rod 1. One end of the fixed rod 1 is fixedly connected to a rubber sleeve 3, which enhances the grip friction of the operator and provides a comfortable and non-slip operating feel. The other end of the fixed rod 1 is provided with a fixed hook 4, which is used to hook the entire device to the ship's side or a specific position, achieving the auxiliary effect of stabilizing the device during the sampling process. The inner wall of the fixed hook 4 is provided with a connecting frame 5, and the bottom of the connecting frame 5 is provided with a connecting ring 6. A quick-release assembly is provided between the connecting frame 5 and the connecting ring 6, which is used to quickly disassemble and assemble the filter part, greatly improving the efficiency of on-site work. The bottom of the connecting ring 6 is fixedly connected to a filter screen 7, which is used to filter target samples in the water. The bottom of the inner wall of the filter screen 7 is fixedly connected to a collector 8, which is used to collect samples and particles that settle from the filter screen 7, achieving the effect of integrating filtration and collection functions into one.
[0035] The adjustment assembly includes a connecting rod 2, which is slidably connected to the inner wall of the fixed rod 1. The connecting rod 2 slides and extends in conjunction with the fixed rod 1, achieving the effect of adjusting the overall working length of the device. One end of the connecting rod 2 is fixedly connected to the outer wall of the fixed hook 4. Multiple locking pins 14 are slidably connected inside the fixed rod 1. One end of each locking pin 14 engages with a groove on the outer wall of the connecting rod 2, achieving precise positioning and locking of the connecting rod 2. Multiple fixing blocks 9 are fixedly connected to the outer wall of the fixed rod 1. Each locking pin 14 has a pushing assembly on its outer wall. This pushing assembly is the core operating unit for unlocking and adjusting. Each pushing assembly includes a pressing plate 11, and each pressing plate 11 is located on the outer wall of the locking pin 14. A rotating bar 10 is fixedly connected between two adjacent fixing blocks 9. Each pressing plate 11 is rotatably connected to the outer wall of the rotating bar 10. The pressing plate 11 rotates in conjunction with the rotating bar 10, providing a lever to reduce effort during the unlocking action. Multiple springs 15 are provided on the outer wall of the fixing rod 1. One end of each spring 15 is fixedly connected to the outer wall of the fixing rod 1, and the other end of each spring 15 is fixedly connected to the outer wall of the pressing plate 11. The spring 15 provides a restoring force to ensure that the locking pin 14 can be automatically pushed to lock after the pressing plate 11 is released, thus enhancing the reliability of the adjustment. Multiple connecting blocks 12 are fixedly connected to the bottom of each pressing plate 11. A rotating bar 13 is fixedly connected between two adjacent connecting blocks 12. Each rotating bar 13 is rotatably connected inside the locking pin 14. The rotating bar 13 rotates in conjunction with the locking pin 14, achieving the effect of smoothly transmitting the pressing action of the pressing plate 11 to the locking pin 14.
[0036] Reference Figures 3-5The quick-release assembly includes multiple locking blocks 23 located on the outer wall of the connecting ring 6. Multiple slots 24 are formed on the outer wall of the connecting ring 6. The locking blocks 23 engage with the inner walls of the slots 24, achieving quick fixing or release of the connecting ring 6. A transmission frame 20 is fixedly connected to one side of each locking block 23. Limiting plates 21 are fixedly connected to both sides of each transmission frame 20. A fixed housing 19 is slidably connected between adjacent transmission frames 20. The limiting plates 21 are slidably connected to the sealing groove surface inside the fixed housing 19. These limiting plates 21 restrict the sliding range of the transmission frame 20, preventing excessive displacement or detachment during movement. A spring 22 is installed inside each fixed housing 19, with both ends fixedly connected to… Between the two transmission frames 20, the second spring 22 provides a continuous outward elastic force to ensure that the locking block 23 can be stably locked into the slot 24, realizing a self-locking function and improving the stability of the connection. Each fixed shell 19 has a slider 17 fixedly connected to its top, and each slider 17 has a limit plate 18 fixedly connected to both sides. Each slider 17 has a connecting block 16 slidably connected to its outer wall. The slider 17 slides in cooperation with the connecting block 16, achieving the effect of guiding the quick-installation assembly to perform disassembly and assembly movements. The limit plate 18 is slidably connected to the surface of the sealing groove inside the connecting block 16. The limit plate 18 is used to ensure that the slider 17 slides smoothly inside the connecting block 16 without coming out, ensuring the structural integrity of the quick-installation assembly. The tops of multiple connecting blocks 16 are fixedly connected to the bottom of the connecting frame 5.
[0037] Working principle: When the overall length of the sampling device needs to be adjusted to adapt to different water depths or operating distances, the operator presses the multiple pressing plates 11 located on the outside of the fixed rod 1. The pressing plates 11 will rotate around the rotating bar 10 as the fulcrum, and in the process, the spring 15 is compressed. At the same time, the pressing plates 11 push the locking pin 14 towards the center of the fixed rod 1 through the connecting block 12 and the rotating bar 13 at the bottom, so that the top of the locking pin 14 disengages from the groove on the outer wall of the connecting rod 2, releasing the lock on the connecting rod 2. At this time, the connecting rod 2 can be freely pulled out and slid inside the fixed rod 1, thereby changing the extension length of the fixed hook 4. After the adjustment is completed, the pressing plates 11 are released. The rebound force of the spring 15 will cause the pressing plates 11 to reset and push the locking pin 14 back into the corresponding groove on the connecting rod 2, thereby reliably fixing the adjusted length. This solves the problem that the traditional sampling rod has a fixed length, cannot adapt to different water depths and working environments, and is inconvenient to operate. It enhances the adaptability of the device to different sampling environments and the convenience of operation.
[0038] When the filter screen 7 needs to be disassembled for cleaning or replacement, the operator presses the two symmetrical transmission brackets 20 on the quick-release assembly inward. The transmission brackets 20 will cause the bottom locking block 23 to retract inward, disengaging it from the slot 24 on the outer wall of the connecting ring 6. At the same time, the spring 22 between the two transmission brackets 20 is stretched. After the locking block 23 separates from the slot 24, the connecting ring 6, along with the filter screen 7 and the collector 8 below, can be removed upwards as a whole. Next, the fixed shell 19 connected to the transmission brackets 20 and the slider 17 on top will be pushed... The connecting block 16 at the bottom of the connecting bracket 5 slides in the groove inside and is limited by the limiting plate 18 to prevent the parts from falling off. The installation process is the opposite. Simply align the connecting ring 6 and press it down. The inclined design of the locking block 23 will cause it to retract automatically. When it reaches the position of the locking groove 24, it will automatically pop out and lock under the elastic force of the spring 22. This solves the problem that the filter screen 7 and the connecting parts are usually fixed by bolts, which is time-consuming and laborious to disassemble and clean, especially when changing the filter screen in the field environment. It improves the cleaning efficiency of the surface of the filter screen 7.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
