Description

Technical Field

[0001] The present invention relates to the technical field of water resource monitoring, and in particular to a hydrological and water resource data acquisition and monitoring device. Background Art

[0002] In the current context where water resources management and environmental protection are becoming increasingly important, the accurate collection and real-time monitoring of hydrological and water resources data has become a vital key technology. With the increasing impact of global climate change and human activities, the rational use and protection of water resources are particularly critical. Accurate hydrological data can not only help us better understand the distribution and changing patterns of water resources, but also have important guiding significance for formulating effective water resources management strategies and environmental protection measures.

[0003] A Chinese patent discloses a hydrological and water resources monitoring device (authorization announcement number CN109141378A). In this patented technology, the water quality monitoring sensor transmits the monitored hydrological information to the central processor. The central processor receives and processes the information, stores one copy of the information in a storage module, and sends one copy to the base station via a wireless transmitter, allowing the base station to monitor the hydrological information in real time and locate the position of the entire device in real time through the Beidou locator.

[0004] With respect to the above and existing related technologies, the inventors believe that the following defects often exist:

[0005] Traditional monitoring devices are usually placed in water for a long time to monitor rivers in real time, which requires the devices to be immersed in water for a long time. When the water environment is polluted and corrosive, the devices may be damaged or affect the monitoring accuracy due to long-term immersion. When the water flow is relatively turbulent, objects such as stones in the water flow may collide with the monitoring device, causing damage to the device, or objects such as water plants in the water flow may be entangled on the surface of the device. After the entanglement, the water plants cannot be removed in time, resulting in the clogging of the device by the water plants. The device cannot normally introduce water resources for testing, affecting the accuracy of the device's monitoring and analysis of various water resources and water quality data, and having a certain impact on the continuous and stable operation of the monitoring equipment.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] Reference Figure 1-Figure 7 As shown, the present invention provides a technical solution: a hydrological and water resources data acquisition and monitoring device, including a bracket 1, a telescopic rod 2 is fixedly connected to the top of the bracket 1, an extension rod 10 is fixedly connected to the bottom output end of the telescopic rod 2, a cross plate 3 is fixedly connected to the bottom of the extension rod 10, a monitoring collector 4 is fixedly connected to the bottom of the cross plate 3, and the monitoring collector 4 includes: a flow meter, a multi-parameter water quality sensor, and a sediment monitor. Four protective shells 5 are provided on the outside of the monitoring collector 4, and a disc 7 is rotatably connected to the top of the cross plate 3, which also includes a filter plate 6 and a cutter 8;

[0035] A rotating assembly is installed on the top of the disc 7. The expansion assembly is in transmission connection with the rotating assembly. The rotating assembly includes:

[0036] Sleeve 9, sleeve 9 is fixedly connected to the top of the cross plate 3, and sliding grooves 11 are opened on both sides of the inner wall of the sleeve 9. The bottom of the telescopic rod 2 is fixedly connected to the sleeve plate 12, and the bottom of the sleeve plate 12 is sleeved on the surface of the extension rod 10. Both sides of the bottom of the sleeve plate 12 are fixedly connected to the extension block 13. The surface of the disc 7 is provided with four arc grooves 14;

[0037] The expansion assembly includes a slide rod 15, which is fixedly connected to the top of the protective shell 5. Long grooves 16 are provided around the cross plate 3. The slide rod 15 is slidably connected to the inner wall of the long groove 16. The slide rod 15 is slidably connected to the inner wall of the arc groove 14. The interior of the protective shell 5 is provided with a contraction groove 17. The filter plate 6 is slidably connected to the inner wall of the contraction groove 17. The bottom of the protective shell 5 is fixedly connected to a bottom plate 18. A fishing net 19 is fixedly connected between the four bottom plates 18. The staff fixes the bracket 1 on the bank of the river so that the bottom of the telescopic rod 2 is aligned with the top of the river. Figure 1 The figure shows the initial state of the device. When the device needs to collect and detect river water resources, the telescopic rod 2 is extended downward through the operation of the telescopic rod 2, so that the extension rod 10 moves down and the monitoring collector 4 at the bottom is extended into the water. In the process of the telescopic rod 2 extending downward, the downward movement of the extension rod 10 will drive the disc 7 and the sleeve 9 to slide downward along the outer side of the sleeve plate 12. The sliding connection between the extension block 13 and the slide 11 makes the sleeve 9 move down to a certain height and the monitoring collector 4 will enter the water flow. After that, the telescopic rod 2 continues to push the extension rod 10 downward, and the extension block 13 enters the arc groove at the top of the slide 11. During the downward movement of the sleeve 9, the sleeve 9 is caused to rotate ninety degrees, thereby driving the disc 7 to rotate at the same time. Since the extension rod 10 is fixed to the cross plate 3 When the disc 7 is connected, the position of the cross plate 3 remains unchanged, which makes the slide bar 15 extend and slide inside the arc groove 14 when the disc 7 rotates, and the slide bar 15 is pushed to move outward along the inner wall of the arc groove 14 through the rotation of the disc 7, and the slide bar 15 slides inside the long groove 16, which makes the slide bar 15 translate outward when the disc 7 rotates, thereby driving the protective shell 5 to expand outward along the trajectory of the long groove 16. At this time, the monitoring collector 4 is already in the water flow, and when the protective shell 5 expands outward, it will push the water grass impurities and other dirt in the water flow outward, so that the dirt is away from the monitoring collector 4, and after the bottom plate 18 and the protective shell 5 are deep in the water, the expansion of the protective shell 5 will also prevent the water grass from being entangled on the outside of the device, and can make the water grass entangled on the outside of the protective shell 5 be stretched and broken;

[0038] During the expansion of the protective shell 5, the four protective shells 5 move away from each other and pull the filter plate 6 to slide out of the contraction groove 17, so that when the protective shell 5 moves to the outermost side, it forms a larger circle with the contraction groove 17. At this time, the fishing net 19 will also be placed at the bottom of the monitoring collector 4 and expand with the movement of the bottom plate 18, so as to surround and protect the monitoring collector 4 through the protective shell 5, the filter plate 6 and the fishing net 19. After that, the water in the river will be filtered into the interior of the monitoring collector 4 through the filter holes of the filter plate 6 and the fishing net 19, thereby preventing the dirt and impurities in the river from adhering to the surface of the monitoring collector 4 and blocking the water inlet of the monitoring collector 4. The monitoring collector 4 contacts the water flow to monitor the water source data, and the flow meter, multi-parameter water quality sensor, The sediment monitor performs multiple analyses and tests on the water flow, analyzing key indicators such as flow rate, turbidity, temperature, pH value, dissolved oxygen, conductivity and sediment content in the water, and then transmits them to the terminal network storage. The user analyzes the water quality status, obtains water quality warning information in a timely manner, and responds quickly to abnormal water quality conditions to ensure the accuracy and reliability of the monitoring data. When the monitoring collector 4 completes the monitoring, the telescopic rod 2 of the device will rise to reset the position of the monitoring collector 4. During this process, the sleeve 9 will rotate in the opposite direction, and the slide bar 15 will move in the opposite direction along the arc groove 14 to reset, so that the protective shell 5 and the bottom plate 18 are close to each other and the fishing net 19 is put into the retraction groove 17. The retraction of the protective shell 5 when closed will also cause the surface aquatic plants to entangle and fall off. After that, the monitoring collector 4 moves up and is lifted to the top of the water surface away from the water flow. This makes the monitoring collector 4 enter the water only when it needs to collect water samples, and it will be drawn out of the water when the device does not need to collect and monitor.

[0039] This design prevents the monitoring collector 4 from being corroded and rusted due to being immersed in water for a long time, or from being in water for a long time to absorb impurities and dirt in the water and become dirty and clogged in the monitoring water inlet. When the monitoring collector 4 is not in water, the protective shell 5 and the bottom plate 18 will shield and protect the outside of the monitoring collector 4 to prevent direct sunlight and foreign objects from directly damaging the monitoring collector 4, thereby extending the service life of the monitoring collector 4 and reducing the damage rate, so that the monitoring collector 4 can operate stably for a long time to effectively collect and monitor water resources, and ensure that any abnormalities in water resources can be detected in time.

[0040] Reference Figure 6 As shown, the hydrological and water resources data acquisition and monitoring device also includes a cutting component, which includes:

[0041] The frame plate 20 and the inner wall of the long groove 16 are provided with a wave groove 21 on both sides. The inner wall of the wave groove 21 is slidably connected with a slider 22. The bottom of the slider 22 is fixedly connected to the tool 8. The surface of the protective shell 5 is fixedly connected with a U-shaped shell 23. The frame plate 20 is slidably connected to the inner wall of the U-shaped shell 23. When the four protective shells 5 move outward and expand, the protective shell 5 will push the frame plate 20 so that the tool 8 moves synchronously with the protective shell 5. The slider 22 is fixed to the tool 8 and will slide along the inner wall of the wave groove 21 while following the translation of the tool 8. The wave-shaped opening of the wave groove 21 causes the horizontal trajectory of the slider 22 to move up and down repeatedly, thereby driving the tool 8 to move up and down repeatedly along the inside of the U-shaped shell 23, so that the roots of plants wrapped around the outside of the protective shell 5 will be cut by the tool 8, and the repeated up and down movement of the tool 8 can form a sawing effect on the plants, so as to increase the cutting and breaking effect of the tool 8 on plants such as aquatic plants, further preventing weeds from being entangled on the surface of the protective shell 5 and affecting the normal operation of the device, and avoiding excessive entanglement of aquatic plants affecting the water flow infiltration into the monitoring collector 4.

[0042] Reference Figure 5 As shown, in this embodiment: both sides of the filter plate 6 are fixedly connected with extension columns 24, and the extension columns 24 are slidably connected to the inner wall of the contraction groove 17. The surface of the filter plate 6 fits with the surface of the openings at both ends of the contraction groove 17. A brush 25 is fixedly connected to one side of the protective shell 5. When the protective shell 5 expands and the filter plate 6 is pulled out from the inside of the contraction groove 17, the brush 25 is set on one side of the contraction groove 17. When the brush 25 is unfolded, one side of the brush 25 will move along the surface of the filter plate 6. The bristles of the brush 25 fit with the surface of the filter plate 6, and the dynamic movement of the filter plate 6 makes The static brush 25 brushes the surface of the extension column 24, thereby ensuring the fluidity of the mesh of the extension column 24, avoiding clogging of the extension column 24 due to long-term use, and achieving a self-cleaning effect. The setting of the extension column 24 can ensure that both sides of the filter plate 6 are always inside the contraction groove 17, avoiding the filter plate 6 from being pulled out from the contraction groove 17, and the surface of the extension column 24 is smooth and presents a round rod state and contacts the inner wall of the contraction groove 17, ensuring that the moving trajectory of the filter plate 6 is restricted while reducing the friction resistance between the filter plate 6 and the contraction groove 17, so that the device can operate smoothly and stably.

[0043] Reference Figure 4 and Figure 7As shown, in this embodiment: the top of the protective shell 5 is rotatably connected to a folding rod 26, the middle part of the folding rod 26 can be folded and rotatable, and the other end of the folding rod 26 is rotatably connected to the surface of the cross plate 3. The folding rod 26 is used to form a conical structure between the protective shell 5 in a closed state and the bottom plate 18, so that when the protective shell 5 is pulled out of the water, the aquatic plants and impurities wrapped around the outside can slide off through the downward conical structure. When the protective shell 5 expands, the folding rod 26 will rotate and fold. Through the downward rotation of the middle part of the folding rod 26, the folding rod 26 is close to the outside of the protective shell 5. At this time, the plant roots wrapped around the surface of the protective shell 5 will be on the surface of the folding rod 26. When the protective shell 5 is reset, the folding rod 26 will rotate to a straight state. Through the inclination angle of the folding rod 26, the aquatic plants are stretched and expanded, so that the wrapped aquatic plants are loosened, and the formation of a conical structure is more conducive to the shedding of the aquatic plants.

[0044] Reference Figure 5 and Figure 6 As shown, in this embodiment: the top of the protective shell 5 is fixedly connected with a baffle 27, and the tool 8 is slidably connected to the inner wall of the baffle 27. The top of the tool 8 is curved outward. When the tool 8 moves outward with the protective shell 5, the top of the tool 8 will also slide along the inside of the baffle 27, wherein the top of the tool 8 is in a curved state, which makes it possible for aquatic plants to gather at the top arc position of the tool 8 when the device is extended into the water, so that the aquatic plants can be contacted and cut by the arc surface of the tool 8, and the tool 8 moves up and down repeatedly, so that the top position of the tool 8 is located inside the baffle 27 for movement. Through the clamping of the two sides of the tool 8 by the inner wall of the baffle 27, the tool 8 that moves up and down repeatedly can scrape off the surface residue through the baffle 27, reducing the residue on the surface of the tool 8, and the baffle 27 set at the bottom of the long groove 16 moves synchronously with the protective shell 5, which can reduce the bottom opening area of ​​the long groove 16 and reduce the probability of dirt entering the long groove 16.

[0045] Reference Figure 7 As shown, in this embodiment: the four bottom plates 18 are conical structures, and the bottom plates 18 gradually tilt inward from top to bottom. The top of the disc 7 is fixedly connected to the top cover 28. When the bottom plates 18 are gathered together, the hole in the center and its conical structure allow the moisture on the surface of the monitoring collector 4 to drip normally and then be discharged from the inside of the protective shell 5 through it. The top cover 28 is arranged on the top of the disc 7 to prevent dirt and impurities on the surface of the disc 7 from clogging the arc groove 14. At the same time, when the device moves upward, the inclined surface of the top cover 28 can divert impurities in the water to the outside to avoid pulling the aquatic plants when the device moves upward and affecting normal operation. The top and bottom of the part that enters the water through this device are both conical structures, so that when the device moves downward, it can automatically push impurities and dirt in the water to the outside through the conical contact surface. At the same time, the conical structure is more conducive to the device diving into the water, avoiding the bottom position being blocked by plants when moving downward.

[0046] Working principle: The telescopic rod 2 extends downward through operation, so that the extension rod 10 moves downward to extend the monitoring collector 4 at the bottom into the water. In the process of the telescopic rod 2 extending downward, the downward movement of the extension rod 10 will drive the disc 7 and the sleeve 9 to slide downward along the outer side of the sleeve plate 12. Through the sliding connection between the extension block 13 and the slide 11, the sleeve 9 moves down to a certain height and the monitoring collector 4 will enter the water flow. After that, the telescopic rod 2 continues to push the extension rod 10 downward, and the extension block 13 will enter the arc groove at the top of the slide 11. During the downward movement of the sleeve 9, the sleeve 9 is caused to rotate ninety degrees, thereby driving the disc 7 to rotate at the same time. Since the extension rod 10 is fixedly connected to the cross plate 3, the position of the cross plate 3 remains unchanged at this time. , which makes the slide bar 15 extend and slide inside the arc groove 14 when the disc 7 rotates, and pushes the slide bar 15 to move outward along the inner wall of the arc groove 14 through the rotation of the disc 7, and the slide bar 15 slides inside the long groove 16, which makes the slide bar 15 translate outward when the disc 7 rotates, thereby driving the protective shell 5 to expand outward along the trajectory of the long groove 16. At this time, the monitoring collector 4 is already in the water flow, and when the protective shell 5 expands outward, it will push dirt such as water plants and impurities in the water flow outward, so that the dirt is away from the monitoring collector 4, and after the bottom plate 18 and the protective shell 5 are deeply immersed in the water, the expansion of the protective shell 5 will also prevent water plants from being entangled on the outside of the device, and can make the water plants entangled on the outside of the protective shell 5 be stretched and broken;

[0047] During the expansion of the protective shell 5, the four protective shells 5 move away from each other and pull the filter plate 6 to slide out of the contraction groove 17, so that when the protective shell 5 moves to the outermost side, it forms a larger circle with the contraction groove 17. At this time, the fishing net 19 will also be placed at the bottom of the monitoring collector 4 and expand with the movement of the bottom plate 18, so as to surround and protect the monitoring collector 4 through the protective shell 5, the filter plate 6 and the fishing net 19. After that, the water in the river will pass through the filter holes of the filter plate 6 and the fishing net 19 to filter into the interior of the monitoring collector 4, and the water source will be monitored by the monitoring collector 4 through contact with the water flow. The flow meter, multi-parameter water quality sensor, The sediment monitor performs multiple analyses and tests on the water flow, analyzing key indicators such as flow rate, turbidity, temperature, pH value, dissolved oxygen, conductivity and sediment content in the water, and then transmits them to the terminal network storage. The user analyzes the water quality, obtains water quality warning information in a timely manner, and responds quickly to abnormal water quality conditions. When the monitoring collector 4 completes the monitoring, the telescopic rod 2 of the device will rise to reset the position of the monitoring collector 4. During this process, the sleeve 9 will rotate in the opposite direction, and the slide bar 15 will move in the opposite direction along the arc groove 14 to reset, so that the protective shell 5 and the bottom plate 18 are close to each other and the fishing net 19 is put into the retraction groove 17. The shrinkage of the protective shell 5 when closed will also cause the aquatic plants on the surface to be entangled and fall off. After that, the monitoring collector 4 moves up and is lifted to the top of the water surface away from the water flow.
