Description

Technical Field

[0001] This invention belongs to the technical field of detection and sampling equipment, specifically referring to a watershed environmental detection device for the surrounding waters of industrial plants. Background Technology

[0002] Industrial plants may generate wastewater containing heavy metals, organic pollutants, or suspended particles during production. If mismanaged or leaking, these pollutants can enter surrounding watersheds via surface runoff or groundwater seepage, posing a serious threat to aquatic ecosystems and the drinking water safety of downstream residents. Therefore, long-term, fixed-point, and regular water quality monitoring of rivers and lakes surrounding industrial plants is necessary to promptly understand pollution levels and implement appropriate countermeasures. However, the watershed environment surrounding industrial plants is complex, and traditional monitoring methods often rely on manual on-site sampling or fixed monitoring stations, which present challenges such as deployment difficulties, inconvenient power supply, and the inability to flexibly schedule sampling.

[0003] Existing environmental monitoring equipment or methods for watersheds surrounding industrial plants have the following main shortcomings: First, most equipment requires external power, and the surrounding watersheds often lack a stable power grid. Although batteries can be manually replaced before and after sampling, this method still relies on periodic on-site operation and cannot achieve truly long-term unattended continuous operation. Furthermore, laying cables is costly and involves a large amount of engineering work, making maintenance difficult in the field. Additionally, after deployment, the solar panels and other energy devices require manual operation, making deployment cumbersome and preventing automatic deployment and buoyancy self-adjustment. Second, traditional sampling devices typically use a fixed structure, allowing sampling only at one location per deployment, making it difficult to automatically complete multiple samplings at different times. Moreover, the water tank's sealing is poor after sampling, easily leading to contamination with upper-layer water or sample leakage, affecting detection accuracy. Third, existing equipment often relies on complex electronic control or remote control commands for counterweight release or component separation, resulting in low reliability in the field. Simultaneously, the sampling process requires regular on-site operation, making unattended automatic timed sampling and sealing impossible. In summary, there is an urgent need for a watershed environmental monitoring device that is self-deployable, self-powered, automatically timed for sampling, and reliably sealed. Summary of the Invention

[0004] In response to the above situation, and to overcome the shortcomings of existing technologies that rely on external power supply, require manual deployment, and cannot automatically and regularly seal and sample, this invention provides an environmental monitoring device for watersheds around industrial plants. This device effectively solves the problems of inconvenient power supply, complex sampling operations, and inability to achieve unattended automatic and timed collection and sealing of water samples by traditional watershed monitoring devices for industrial plants.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an environmental monitoring device for watersheds around industrial plants, including an automatic deployment structure for new energy equipment, a counterweight rotation and release structure, and a pneumatic rotation water sample extraction device. The automatic deployment structure for new energy equipment is suspended on the surface of the river. The counterweight rotation and release structure is engaged and installed at the center of the automatic deployment structure for new energy equipment. The pneumatic rotation water sample extraction device is connected to the counterweight rotation and release structure through a flexible hose. The pneumatic rotation water sample extraction device is located below the automatic deployment structure for new energy equipment and is engaged and connected to the counterweight rotation and release structure.

[0006] Furthermore, the automatic deployment structure of the new energy equipment includes a hollow column, a limiting base plate, an internal slider, a hexagonal retaining ring, a hinge bracket A, a hinge bracket B, a solar panel A, and a solar panel B. The limiting base plate is fixedly connected to the counterweight rotation release structure. The hollow column is fixedly installed at the center of the limiting base plate. The internal slider engages and slides inside the hollow column. The hexagonal retaining ring engages and slides on the outer wall of the hollow column. The hinge bracket A is hinged to the hexagonal retaining ring. Both solar panels A and B are hinged to the side wall of the limiting base plate. The hinge bracket B is hinged to the side wall of the limiting base plate. Solar panels A and B are respectively hinged to two sets of hinge brackets B. The hinge bracket A is engaged and connected to the hinge joint between solar panels A and B.

[0007] Furthermore, the hollow column has a sliding groove on its side wall, and the built-in slider and the hexagonal retaining ring are fixedly connected through the gap of the sliding groove, so that the built-in slider drives the hexagonal retaining ring to move.

[0008] Furthermore, the bottom walls of solar panel A and solar panel B are respectively provided with water surface suspending airbags to provide buoyancy for the equipment to float on the water surface.

[0009] Furthermore, the counterweight rotation release structure includes an adjusting disc, bevel gear A, bevel gear B, a bottom slot, a rotating block, and a rotating chuck. The adjusting disc is fixedly installed on the bottom wall of the limiting base plate via a bracket. The bevel gear B is engaged and rotatably installed on the top wall of the adjusting disc, and is positioned between the adjusting disc and the limiting base plate. The bevel gear A meshes with the bevel gear B. The bevel gear A is perpendicular to the limiting base plate and penetrates both the upper and lower walls of the limiting base plate. The bevel gear A is driven by a motor. The bottom slot is located on the bottom wall of the adjusting disc. The rotating block engages and slides within the bottom slot. The rotating chuck is fixedly connected to the rotating block, and the rotating block is positioned on the side wall of the rotating chuck.

[0010] Furthermore, the bottom slot is designed as an arc-shaped structure, and both the rotating block and the bottom slot have a T-shaped cross-section. In order to release the T-shaped rotating block from one end of the bottom slot, the width of the end cross-section of the bottom slot is greater than the width of the middle cross-section of the bottom slot. In order to drive the rotating block when the bevel gear B rotates, a locking pin is provided on the top wall of the rotating chuck, and the locking pin engages in the slot of the bottom wall of the bevel gear B.

[0011] Furthermore, the pneumatic rotary water sample extraction device includes a pneumatic airbag B, an adjusting sleeve, a rotating adjusting column, a rotating limiting plate, a side positioning column, a notch guide rail, a water tank, a rotating column, and a tank placement base. The pneumatic airbag B is disposed on the bottom wall of the rotating chuck, and the side positioning column is fixedly installed on the side wall of the rotating chuck. The adjusting sleeve is fixedly bonded to the pneumatic airbag B. The expansion of the pneumatic airbag B causes the adjusting sleeve to slide downward. The rotating adjusting column engages and rotates within the adjusting sleeve. Inside the sleeve, the rotating limiting plate is fixedly installed on the bottom wall of the side positioning column, and the rotating adjusting column is engaged and rotated at the center of the rotating limiting plate. The notch guide rail is set on the bottom wall of the rotating limiting plate. The rotating column passes through the center of the rotating limiting plate and is fixedly connected to the rotating adjusting column. The center of the tank placement base coincides with the center of the rotating column, and the two are fixedly connected. The water tank is engaged and installed on the upper wall of the tank placement base, and the water tank slides along the notch guide rail.

[0012] Furthermore, the pneumatic airbag B is driven by a micro air pump connected to an air pipe. The micro air pump is installed on the upper wall of the limiting base plate to ensure that the equipment is always placed on the water surface.

[0013] Furthermore, the cross-section of the notch guide rail is set as an inverted isosceles trapezoid, and the top wall of the water tank is provided with an arc-shaped groove with an isosceles trapezoidal cross-section. The arc-shaped groove on the top wall of the water tank slides along the notch guide rail. The notch guide rail has both a guiding function for the water tank and a sealing effect for the water tank.

[0014] Furthermore, the water tank is designed as a cylindrical structure, and a sealed ball and spring are installed inside the water tank. When the underwater pressure is greater than atmospheric pressure, the water flow will squeeze the ball into the tank.

[0015] Furthermore, the side wall of the rotating adjusting column is provided with an arc-shaped groove and a straight groove, the ends of which are connected to form a closed groove. The inner wall of the adjusting sleeve is provided with a protrusion, which slides along the arc-shaped groove and the straight groove. A return spring is provided between the top wall of the adjusting sleeve and the top wall of the rotating adjusting column.

[0016] Furthermore, the hollow column, limiting base plate, adjusting disc, rotating chuck, tank placement base, and rotating limiting disc all have small holes penetrating the upper and lower walls at their centers. A thin rope is placed inside the small hole, with one end of the rope fixed to the built-in slider. A conical counterweight is placed on the other end of the rope, allowing a clamp to be placed on it. The diameter of the clamp is larger than the diameter of the hole through which the rope slides within the device. The clamp can limit the length of the rope entering the water. The position of the clamp on the rope can be adjusted according to the water depth, thereby changing the length of the rope entering the water.

[0017] Furthermore, a central controller and an energy storage battery are provided on the upper wall of the limiting base plate, and an indicator light is provided on the side wall at the top of the hollow column. The central controller is connected to the indicator light, the motor, and the air pump respectively.

[0018] Furthermore, the top wall of the tank placement chassis is provided with a T-shaped slot, and the bottom wall of the water tank is provided with a T-shaped locking block. After the water tank is installed, the T-shaped slot is sealed with a sealing block.

[0019] This solution provides a watershed environmental monitoring device for the vicinity of industrial plants, which has the following beneficial effects: (1) In the automatic deployment structure of the new energy equipment of this application, when the counterweight sinks, the built-in slider and hexagonal retainer are pulled by the thin rope, which drives the hinge bracket to automatically unfold and place the solar panel on the water surface. At the same time, the contact area between the water surface suspended airbag on the bottom wall of the solar panel and the water surface increases, which not only improves the buoyancy stability of the equipment on the water surface, but also realizes the automatic deployment and energy collection of the solar panel, and the deployment can be completed without manual intervention. (2) In the counterweight rotation release structure of this application, the motor drives the bevel gear transmission to make the rotating block slide along the bottom slot. When the rotating block moves to the end of the bottom slot, it automatically falls off, realizing the controllable separation of the counterweight rotation release structure and the automatic unfolding structure of the new energy equipment, thereby triggering the unfolding action of the solar panel. The structure is compact and the action is reliable, avoiding the use of complex control components. (3) In the pneumatic rotating water sample extraction device of this application, the pneumatic airbag is expanded by the air pump to drive the adjustment sleeve to slide. The protrusion slides along the arc groove and straight groove on the rotating adjustment column, so that the tank placement base rotates intermittently, driving the water tank to move along the notch guide rail to the notch to automatically enter water for sampling. After rotation, the water inlet on the top wall of the water tank is sealed by the notch guide rail, realizing automatic water sample collection and sealing at different time points without human supervision.

The adjusting sleeve 21 is fixedly bonded to the pneumatic airbag B20, and the rotating adjusting column 22 is engaged and rotatably mounted inside the adjusting sleeve 21. The rotating limiting plate 23 is fixedly installed on the bottom wall of the side positioning column 24, and the rotating adjusting column 22 is engaged and rotated at the center of the rotating limiting plate 23. The notch guide rail 25 is set on the bottom wall of the rotating limiting plate 23. The rotating column 27 passes through the center of the rotating limiting plate 23 and is fixedly connected to the rotating adjusting column 22. The center of the tank placement base 28 coincides with the center of the rotating column 27. The water tank 26 is engaged and installed on the upper wall of the tank placement base 28. The water tank 26 slides along the notch guide rail 25.

[0027] The cross-section of the notched guide rail 25 is an inverted isosceles trapezoid, and the top wall of the water tank 26 is provided with an arc-shaped groove with an isosceles trapezoidal cross-section. The arc-shaped groove on the top wall of the water tank 26 slides along the notched guide rail 25.

[0028] The water tank 26 is designed as a cylindrical structure, and a sealed ball and spring are installed inside the water tank 26.

The internal slider 6 engages and slides inside the hollow column 4. The hexagonal retaining ring 7 engages and slides on the outer wall of the hollow column 4. The hinge bracket A8 is hinged to the hexagonal retaining ring 7. The solar panels A10 and B11 are both hinged to the side wall of the limiting base plate 5. The hinge bracket B9 is hinged to the side wall of the limiting base plate 5. The solar panels A10 and B11 are respectively hinged to two sets of hinge brackets B9. The hinge bracket A8 is engaged and connected to the hinge joint between the solar panels A10 and B11.

[0031] The hollow column 4 has a sliding groove on its side wall, and the built-in slider 6 and hexagonal retaining ring 7 are fixedly connected through the gap of the sliding groove.

[0032] The bottom walls of solar panels A10 and B11 are respectively equipped with water surface suspending airbags 12.

[0033] The counterweight rotation release structure 2 includes an adjusting disc 13, a bevel gear A14, a bevel gear B15, a bottom slot 16, a rotating block 17, and a rotating chuck 18. The adjusting disc 13 is fixedly installed on the bottom wall of the limiting base plate 5 by a bracket. The bevel gear B15 is engaged and rotatably installed on the top wall of the adjusting disc 13 and is located between the adjusting disc 13 and the limiting base plate 5. The bevel gear A14 is meshed with the bevel gear B15 and is perpendicular to the limiting base plate 5. The bevel gear A14 passes through the upper and lower walls of the limiting base plate 5 and is driven by a motor. The bottom slot 16 is located on the bottom wall of the adjusting disc 13. The rotating block 17 engages and slides within the bottom slot 16. The rotating chuck 18 is fixedly connected to the rotating block 17 and is located on the side wall of the rotating chuck 18.

[0034] The bottom slot 16 is designed with an arc shape, and the cross-sections of the rotating block 17 and the bottom slot 16 are both designed with a T-shape. The width of the end cross-section of the bottom slot 16 is greater than the width of the middle cross-section of the bottom slot 16. The top wall of the rotating chuck 18 is provided with a locking pin 19, which engages in the slot of the bottom wall of the bevel gear B15.

[0035] The pneumatic airbag B20 is driven by an air pump connected to an air pipe, and the air pump is located on the upper wall of the limiting base plate 5.

[0036] Hollow column 4, limiting base plate 5, adjusting disc 13, rotating chuck 18, tank placement base plate 28, and rotating limiting disc 23 have small holes penetrating the upper and lower walls at their center. A thin rope is placed inside the small hole. One end of the thin rope is fixed on the built-in slider 6, and a conical counterweight is placed on the other end of the thin rope.

[0037] The upper wall of the limiting base plate 5 is equipped with a central controller and an energy storage battery, and the side wall at the top of the hollow column 4 is equipped with an indicator light. The central controller is connected to the indicator light, the motor, and the air pump.

[0038] The top wall of the tank placement base 28 is provided with a T-shaped slot, and the bottom wall of the water tank 26 is provided with a T-shaped block.

[0039] In practical use, the equipment in its retracted state is thrown into the water area around the factory. The buoyancy of the water surface suspension airbag 12 overcomes the weight of the counterweight and suspends the equipment on the water surface. The length of the thin rope between the counterweight and the tank placement base 28 has been fixed by clamps before the equipment is put into the watershed. The remaining part of the thin rope is hidden in the hollow column 4. The thin rope is always taut in the pneumatic rotating water sample extraction device 3. The central controller controls the motor to power on and work. The bevel gear A14 rotates, and the bevel gear B15 rotates horizontally under meshing action. The rotation of the bevel gear B15 drives the lower locking pin 19 to rotate. The locking pin 19 drives the rotating chuck 18 to rotate. When the rotating chuck 18 rotates, it causes the rotating block 17 to engage and slide in the bottom slot 16 in the adjusting disc 13. When the rotating block 17 rotates to the end of the bottom slot 16, the rotating block 17 falls out of the bottom slot 16. As the pneumatic rotating water sample extraction device 3 separates from the new energy equipment automatic deployment structure 1, the counterweight descends to the bottom of the river. The thin rope pulls the built-in slider 6 to slide along the slot inside the hollow column 4. The hexagonal retaining ring 7 slides, the hinge bracket A8 is pressed down, and the angle between the solar panel A10, solar panel B11 and the hollow column 4 changes. The solar panel A10 and solar panel B11 unfold at the height of the limiting base plate 5, so that the solar panel composed of solar panel A10 and solar panel B11 is placed flat on the water surface. The contact area between the water surface suspension airbag 12 and the water surface increases, improving the buoyancy of the equipment on the water surface. The central controller sets the time interval for the air pump to work. When the set time condition is met, the air pump is powered on, the pneumatic air bag B20 is inflated, the adjusting sleeve 21 slides down along the side positioning column 24 under the action of the pneumatic air bag B20, the protrusion 31 slides along the arc groove 29 and the straight groove 30, the protrusion 31 controls the rotation of the rotating adjusting column 22 to rotate, the tank placement base 28 rotates with the rotating adjusting column 22, the water tank 26 slides along the notched guide rail 25, when the water tank 26 moves to the notch of the notched guide rail 25, the top of the water tank 26 contacts the external water environment, and the water inlet opens under the pressure of the water pressure; The pressure of the spring inside the water tank 26 cannot overcome the underwater pressure. Under the action of water pressure, the small ball inside the water tank 26 is misaligned with the water inlet of the water tank 26. The water sample flows into the water tank 26. After sampling for a period of time, the control tank placement base 28 continues to rotate, so that the notch guide rail 25 seals and blocks the water inlet of the water tank 26. After one sampling is completed, wait for the next time point to sample the water flow area; During the sampling process, the solar panels convert solar energy into electrical energy to power the central controller; At night, the signal lights on the hollow column 4 are powered on and illuminate, providing a warning to ships in the river basin and allowing them to avoid the equipment. When it is necessary to remove the water tank 26 from the tank placement base 28, rotate the tank placement base 28, move the water tank 26 to the notch of the notch guide rail 25, pull the water tank 26 outward, and the water tank 26 can be removed. Then send the water sample for testing. The equipment requires no human monitoring or operation, nor does it require external power supply, making it simple to operate.
