Description

TECHNICAL FIELD

[0002] In the management of hydrological and water resources and the protection of water environment, real-time and accurate grasp of the water environment status is the core prerequisite for pollution early warning, emergency disposal and ecological management. At present, the buoy-type online automatic monitoring system composed of modern sensor technology, automatic measurement technology, automatic control technology, computer application technology, special analysis software and communication network has become the key means to achieve this goal. This system can continuously, timely and accurately monitor the water quality changes, the growth status of aquatic plants and the surrounding climate conditions of the on-site water area, and truly reflect the water environment status and evolution trend, providing important scientific basis for the protection and pollution emergency response of lakes, reservoirs, estuaries and other water bodies.

[0003] However, the existing buoy-type water quality detection device is restricted by its own structural stability and measurement accuracy. The existing buoy-type water quality detection device can usually only be deployed in areas with stable water flow, the main reason being that too fast water flow can easily cause the buoy to overturn, causing damage to the equipment; in addition, fast water flow can interfere with the measurement environment of the sensor, causing deviation of the water quality parameter detection results, and cannot guarantee the accuracy of the data.

[0004] However, in actual application, there is also an urgent monitoring demand in water areas such as rivers and reservoirs with fast water flow. Due to the strong water flow power and fast pollution diffusion speed in water areas with fast water flow, the demand for real-time monitoring is more urgent in order to prevent pollution diffusion risks, but the existing buoy-type water quality detection device cannot meet the dual requirements of "stable operation" and "accurate monitoring" in water areas with fast water flow, resulting in that the existing buoy-type water quality detection device cannot effectively monitor the hydrological and water resources in water areas with fast water flow.

[0036] As shown in Figures 1 to 11 The hydrological and water resource automatic monitoring system provided by the embodiment of the present application comprises a floating module, a monitoring module and a regulating module.

[0037] The floating module comprises a floating block 110, which can float on the water surface under the action of its own buoyancy. The upper surface of the floating block 110 is always above the water surface. A power generation module and a monitoring module are arranged on the upper surface of the floating block 110. In this embodiment, the power generation module comprises a solar panel 120 and a storage battery. The storage battery is arranged inside the floating block 110. The solar panel 120 can convert solar energy into electric energy. The storage battery can store the electric energy generated by the solar panel 120 and provide sufficient electric energy for the entire device. The monitoring module comprises a camera 130 arranged on the upper surface of the floating block 110. The storage battery can provide electric energy for the camera 130. The camera 130 can take pictures of the water surface environment.

[0038] The monitoring module is connected to the floating module through a connecting module. When the floating block 110 floats on the water surface, the monitoring module is located underwater. The monitoring module can monitor hydrological data. The connecting module can adjust the distance between the monitoring module and the floating module, so that the monitoring module can monitor hydrological data at a specified depth, thereby increasing the application range of the device.

[0039] The regulating module comprises a first regulating assembly and a second regulating assembly. The first regulating assembly is used to stabilize the state of the monitoring module when the water flow impacts the monitoring module, thereby avoiding the probability of shaking of the monitoring module and further avoiding the probability of overturning of the floating module. The second regulating assembly is used to prolong the contact time of water at a specified depth with the monitoring module, thereby reducing the interference of the water flow on the monitoring module and further improving the accuracy of the monitoring module in monitoring hydrological data.

[0040] In one of the embodiments, the connecting module comprises a telescopic main shaft 210 for connecting the floating module and the monitoring module; the telescopic main shaft 210 can adjust the length according to the requirement; the power generation module is used for providing the electric energy for the telescopic main shaft 210. Specifically, the connecting module further comprises a control cylinder fixedly arranged on the floating block 110, the power output shaft of the control cylinder is vertically downward, the telescopic main shaft 210 is hollow inside, the upper end of the telescopic main shaft 210 is coaxially fixedly connected with the cylinder body of the control cylinder, the lower end of the telescopic main shaft 210 is fixedly connected with the power output shaft of the control cylinder inside, the storage battery can provide the electric power for the length change of the control cylinder, and the length of the telescopic main shaft 210 can be changed when the length of the control cylinder changes. Further, the lower end of the telescopic main shaft 210 is connected with the monitoring module, and when it is required to monitor the hydrological data of the specified depth, the length of the telescopic main shaft 210 can be controlled by the staff to deliver the monitoring module to the water area of the specified depth.

[0041] In one of the embodiments, the first regulating assembly comprises a plurality of guide arc plates 220 and a plurality of connecting rings 230, the connecting ring 230 is coaxially rotationally connected with the telescopic main shaft 210, and the plurality of connecting rings 230 are distributed on the telescopic main shaft 210 at intervals. Each of the guide arc plates 220 is fixedly connected with one of the connecting rings 230, when the floating block 110 floats on the water surface, the telescopic main shaft 210 is in a vertical state, the guide arc plate 220 has an upper surface and a lower surface, wherein the upper surface is arranged as a horizontal plane, and the lower surface is arranged as an arc surface with a middle part upwardly protruding, according to the Bernoulli principle, the flowing water has a greater flow rate on the lower surface than on the upper surface when passing through the upper surface and the lower surface, so that a pressure difference is generated between the upper surface and the lower surface of the guide arc plate 220, and the guide arc plate 220 has a downward movement trend under the action of the pressure difference, which is transmitted to the telescopic main shaft 210 through the connecting ring 230, thereby enhancing the stability of the telescopic main shaft 210. Further, the guide arc plate 220 is connected with the telescopic main shaft 210 through the connecting ring 230, and when the direction of the water flow changes, the guide arc plate 220 can adjust the position under the guidance of the water flow, thereby ensuring that the guide arc plate 220 can effectively extrude the axial direction of the telescopic main shaft 210.

[0042] In one embodiment, the second control component includes a sensing cylinder 310, a transmission component, and a mounting box 320. The mounting box 320 is coaxially rotatably connected to the lower end of the telescopic main shaft 210. Further, to ensure sufficient installation space at the lower end of the telescopic main shaft 210, a positioning sleeve 330 is coaxially fixedly installed at the lower end of the telescopic main shaft 210. The positioning sleeve 330 is hollow inside, and the mounting box 320 is coaxially rotatably connected to the positioning sleeve 330. The mounting box 320 has a monitoring channel 321 penetrating its sidewall. A monitoring module is disposed within the monitoring channel 321, allowing water to enter. The monitoring module includes multiple monitoring sensors 322, which can monitor the water within the monitoring channel 321. The monitoring channel 321 passes through the circumferential sidewall of the mounting box 320 and is located along the axis of the mounting box 320. Both ends of the monitoring channel 321 are equipped with barrier nets 323 to prevent debris such as tree branches from entering the monitoring channel 321. The sensing cylinder 310 is coaxially rotatably connected to the mounting box 320 and is coaxially rotatably sleeved on the outside of the positioning sleeve 330. When water flows through the sensing cylinder 310, it can drive the sensing cylinder 310 to rotate outside the positioning sleeve 330. A transmission component is located between the sensing cylinder 310 and the mounting box 320. When the sensing cylinder 310 rotates, the mounting box 320 rotates relative to the positioning sleeve 330. This rotation of the mounting box 320 changes the orientation of the monitoring channel 321, causing it to form an angle with the water flow direction, thereby reducing the water flow velocity within the monitoring channel 321. Furthermore, during the rotation of the mounting box 320, the orientation of the monitoring channel 321 may be parallel to or at an angle to the direction of the water flow. When the mounting box 320 rotates 90 degrees, the water flow speed entering the monitoring channel 321 is the lowest. At this time, the monitoring module monitors the hydrological data inside the monitoring channel 321, extending the contact time between the water at the specified depth and the monitoring module.

[0043] Furthermore, during the rotation of the installation box 320, the orientation of the monitoring channel 321 may be parallel to or at an angle to the direction of the water flow. When the installation box 320 rotates 180 degrees, the direction of the water flow into the monitoring channel 321 changes. During this process, the water inside the monitoring channel 321 is replaced. At the same time, the water flow can backwash the barrier net 323, reducing the blockage caused by impurities.

[0044] In one of the embodiments, the transmission member comprises a transmission sleeve 340, a transmission shaft 350, a torsion spring 360 and a speed reduction gear set. The transmission sleeve 340 is coaxially connected to the lower end of the telescopic main shaft 210, and is arranged inside the positioning sleeve 330. The fixed cover is fixedly arranged on the positioning sleeve 330. One end of the transmission shaft 350 is coaxially arranged inside the transmission sleeve 340. The torsion spring 360 is arranged between the outer side wall of the transmission shaft 350 and the inner side wall of the transmission sleeve 340. When the transmission sleeve 340 rotates, the transmission shaft 350 rotates through the torsion spring 360. The speed reduction gear set comprises a center tooth sleeve 370, a transmission gear 380 and a gear ring 390. The center tooth sleeve 370 is coaxially arranged outside the transmission shaft 350. When the transmission shaft 350 rotates, the center tooth sleeve 370 rotates. The center tooth sleeve 370 is coaxially connected to the mounting box 320. The transmission gear 380 is rotatably connected to the fixed cover. The gear ring 390 is coaxially fixedly connected to the mounting box 320. The transmission gear 380 is arranged between the center tooth sleeve 370 and the gear ring 390, and simultaneously engages the center tooth sleeve 370 and the gear ring 390. The rotation speed of the center tooth sleeve 370 is greater than that of the gear ring 390, so as to avoid the rotation speed of the mounting box 320 being too fast, and to ensure that new water enters the monitoring channel 321 at a slow speed.

[0045] In one of the embodiments, the transmission member can also limit the rotation speed of the mounting box 320 when the induction cylinder 310 rotates. Specifically, when the water flow speed is too fast, the rotation speed of the mounting box 320 is still too fast through the transmission of the speed reduction gear, and the plurality of monitoring sensors 322 cannot accurately monitor the hydrological data. At this time, the maximum rotation speed of the mounting box 320 limited by the transmission member is less than the second preset value, so as to ensure that the plurality of monitoring sensors 322 arranged in the mounting box 320 can accurately monitor the hydrological data when the water flow is too fast. The second preset value is a parameter artificially set.

[0046] Further, the transmission member further comprises magnetic columns 410, the transmission shaft 350 is a metal with magnetism, for example, elemental metal or alloy of iron metal, cobalt metal, nickel metal; the inner diameter of the central tooth sleeve 370 is larger than the outer diameter of the transmission shaft 350, so that there is a gap between the central tooth sleeve 370 and the transmission shaft 350, the inner side wall of the central tooth sleeve 370 is provided with a plurality of installation grooves opening towards the axis of the central tooth sleeve 370, the plurality of installation grooves are uniformly distributed in the circumferential direction of the central tooth sleeve 370, and the installation grooves extend in the radial direction of the central tooth sleeve 370. The magnetic columns 410 have magnetism, and a plurality of magnetic columns 410 are provided, each magnetic column 410 is slidingly arranged in one installation groove. A push spring 430 is arranged between the end of the installation groove and one end of the magnetic column 410, the push spring 430 is in a compressed state, under the action of magnetic force between the push spring 430 and the magnetic column 410 and the transmission shaft 350, in the initial state, the magnetic column 410 is in an adsorbed state with the transmission shaft 350. Further, the magnetic column 410 has a relatively high weight, when the central tooth sleeve 370 rotates, the magnetic column 410 will be subjected to centrifugal force, when the rotating speed of the central tooth sleeve 370 reaches a first preset value, the magnetic column 410 will be instantaneously separated from the transmission shaft 350, at the same time, the centrifugal force of the magnetic column 410 will extrude the push spring 430, so that the magnetic column 410 enters the installation groove, thereby cutting off the transmission between the transmission shaft 350 and the central tooth sleeve 370, causing the rotating speed of the mounting box 320 not to exceed a second preset value. When the transmission between the transmission shaft 350 and the central tooth sleeve 370 is cut off, the torsional spring 360 between the transmission shaft 350 and the transmission sleeve 340 resets. With the gradual slowing down of the speed of the mounting box 320, the rotating speed of the central tooth sleeve 370 gradually decreases, the magnetic column 410 again contacts the transmission shaft 350 under the action of the push spring 430 and the magnetic force, the transmission shaft 350 and the central tooth sleeve 370 are again in transmission connection, so that the mounting box 320 continues to rotate.

[0047] In one of the embodiments, the induction cylinder 310 comprises a first cylinder body 440 and a second cylinder body 450, the first cylinder body 440 and the second cylinder body 450 are sleeved outside the positioning sleeve 330, the first cylinder body 440 and the second cylinder body 450 are arranged in the axial direction of the transmission sleeve 340, the first cylinder body 440 is internally provided with a first spoiler 441, the second cylinder body 450 is internally provided with a second spoiler 451, the first spoiler 441 and the second spoiler 451 are both arranged in an arc shape, and the first spoiler 441 and the second spoiler 451 are both provided with a plurality of spoilers, the plurality of first spoilers 441 are arranged in a vortex inside the first cylinder body 440, the plurality of second spoilers 451 are arranged in a vortex inside the second cylinder body 450, and the vortex direction of the plurality of first spoilers 441 inside the first cylinder body 440 is opposite to the vortex direction of the plurality of second spoilers 451 inside the second cylinder body 450. The outer surface of the first cylinder body 440 and the outer surface of the second cylinder body 450 are both provided with water-permeable holes, in the water flow, the water flow can enter the inside of the first cylinder body 440 and the second cylinder body 450, under the action of the plurality of first spoilers 441 and the second spoilers 451, the first cylinder body 440 or the second cylinder body 450 rotates, and the first cylinder body 440 or the second cylinder body 450 can drive the transmission sleeve 340 to rotate when rotating. Further, by arranging the first cylinder body 440 and the second cylinder body 450, it is ensured that the transmission sleeve 340 can still rotate when the water flow flows in different directions.

[0048] In one of the embodiments, the first cylinder body 440 is fixedly provided with a first transmission ring 510, the second cylinder body 450 is fixedly provided with a second transmission ring 530, a first gear 520 is arranged between the first transmission ring 510 and the transmission sleeve 340, the first gear 520 is rotatably connected to the positioning sleeve 330 and penetrates the positioning sleeve 330. A second gear 540 is arranged between the second transmission ring 530 and the transmission sleeve 340, one of the second gears 540 engages with the second transmission ring 530, the other second gear 540 engages with the transmission sleeve 340, the two second gears 540 engage with each other, the two second gears 540 are both rotatably connected to the positioning sleeve 330, and the two second gears 540 both penetrate the positioning sleeve 330. By arranging one first gear 520 and two second gears 540, it is ensured that the transmission sleeve 340 can rotate in a constant direction when the first cylinder body 440 or the second cylinder body 450 rotates, avoiding the situation that the first cylinder body 440 and the second cylinder body 450 are stuck when the water flow suddenly changes.

[0049] Further, when the first barrel 440 is driven to rotate by the water flow, the reverse transmission of the transmission sleeve 340, the second transmission ring 530 and the two second gears 540 causes the second barrel 450 to rotate simultaneously with the first barrel 440, and the rotating directions of the second barrel 450 and the first barrel 440 are opposite, the rotating torques of the first barrel 440 and the second barrel 450 with opposite rotating directions cancel each other in the rotating process, thereby improving the stability of the telescopic main shaft 210 in the working process.

[0050] In one of the embodiments, the monitoring channel 321 is provided with a fixing support 610, and the fixing support 610 is provided with a cleaning brush 620, the cleaning brush 620 is always in contact with the monitoring sensor 322, the monitoring sensor 322 is arranged at the axis position of the installation box 320, the telescopic main shaft 210 extends into the monitoring channel 321, and the monitoring sensor 322 is arranged on the telescopic main shaft 210, when the installation box 320 rotates, the cleaning brush 620 can clean the outer surface of the monitoring sensor 322, thereby preventing the surface of the monitoring sensor 322 from being attached by microorganisms in the water.

[0051] In other embodiments, the cleaning brush 620 does not contact the outer surface of the monitoring sensor 322 in the initial state, when the impurities accumulate on the outer surface of the monitoring sensor 322 to a certain thickness, the impurities contact the cleaning brush 620, thereby cleaning the thicker impurities, and preventing the cleaning brush 620 from always cleaning the outer surface of the monitoring sensor 322 to cause the abrasion of the monitoring sensor 322 and the cleaning brush 620.
