Description

Technical Field

[0001] This invention belongs to the field of environmental protection technology, specifically relating to an adaptive underwater waste liquid collection device and a waste liquid collection method. Background Technology

[0002] With the rapid rise and development of industry, large amounts of industrial wastewater containing various pollutants are continuously discharged into oceans and lakes, making the treatment of underwater wastewater an urgent environmental problem.

[0003] Current methods for collecting underwater waste liquid are quite limited. Traditional suction methods are often constrained by factors such as water depth and current, making it difficult to accurately locate and collect waste liquid. Traditional waste liquid recovery methods usually require external power and manual operation to control the opening and closing of the collection tank. Waste liquid collection in water faces many difficulties, especially in complex underwater terrain conditions, such as areas with crisscrossing ditches and reefs. The collection work faces even greater challenges, including difficult operation, low efficiency, and potential environmental impact.

[0004] Therefore, developing a device that can automatically open and close the cover without external energy or human intervention, adapting to underwater pressure and specific environmental conditions, is crucial for improving operational efficiency and reducing environmental impact. Summary of the Invention

[0005] To address the problems existing in the prior art mentioned in the background section, this invention proposes an adaptive underwater waste liquid collection device. Utilizing changes in water pressure and density, it achieves automatic opening and closing of the lid without external energy supply or manual operation. This device can adapt to the pressure and low temperature conditions of the underwater environment, ensuring stable and reliable operation in extreme environments, and improving the efficiency and safety of waste liquid recycling. This invention also proposes an underwater waste liquid collection method, providing a simple, efficient, and environmentally friendly solution that improves operational efficiency and reduces operational difficulty.

[0016] A method for collecting underwater waste liquid, using any of the above-described adaptive underwater waste liquid collection devices, includes the following steps:

[0017] S1: First, place the waste liquid recovery tank in water. When the waste liquid recovery tank sinks to the target area in the water, the spring in the first working box will be compressed and respond to perform the opening operation.

[0018] S2: When the waste liquid recovery tank is full, the density of the surrounding water and waste liquid mixture increases, and the spring in the second working box responds to the pressure, thus performing the closing operation.

[0019] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0020] (1) The underwater waste liquid adaptive collection device of the present invention is designed for efficient and environmentally friendly recycling of underwater waste liquid. It ingeniously combines depth sensing, density change sensing and a precision gear system, and achieves automatic control through the spring mechanism and float action in the working box; the device uses the water pressure and density change of the water-waste liquid mixture to automatically adjust the spring pressure, thereby driving the gear system to perform the opening and closing operation of the cover. The eccentric hole design ensures the unidirectionality and stability of the gear movement, avoids the possibility of reverse movement or misoperation, enhances the reliability of the device in complex underwater environments, and provides an effective technical means for underwater environmental protection.

[0021] (2) The device of the present invention comprises two independent working chambers, each containing a carefully designed spring. These springs not only have different elastic coefficients but are also specially treated to adapt to the pressure environment underwater. The core design of the spring system lies in its ability to sense changes in the pressure and density of the surrounding environment and adjust the elastic force accordingly. This adaptive mechanism enables the working chambers to open and close automatically under underwater conditions without the need for an external power source or manual intervention.

[0022] (3) The float of the present invention primarily functions to drive the compression and release of a spring by utilizing the pressure of water and the density change of the water-waste liquid mixture. The design of the float fully considers the special characteristics of the underwater environment, such as pressure and low temperature conditions. The material selection and shape design of the float aim to minimize resistance and improve responsiveness, thereby ensuring efficient operation under various environmental conditions.

[0023] (4) The underwater waste liquid collection method of the present invention provides a simple, efficient and environmentally friendly collection method, which improves work efficiency and reduces the difficulty of operation.

[0024] (5) The underwater waste liquid collection method of the present invention adopts a purely mechanical structure design, which features simple structure, low failure rate, and high safety. Compared with traditional methods that rely on electronic sensors, it exhibits significant advantages. It is especially suitable for application scenarios such as underwater waste liquid recycling, which have high requirements for equipment reliability, environmental adaptability, and safety.

[0029] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] like Figure 1-4 As shown, the underwater waste liquid adaptive collection device provided in this embodiment mainly includes an opening device and a closing device connected to the lid 13 of the waste liquid recycling tank; by utilizing the pressure and density changes of water to activate the opening device and the closing device, the lid 13 of the waste liquid recycling tank is automatically opened and closed.

[0031] In this embodiment, the waste liquid recycling tank adopts a cylindrical design, which is a commercially available product.

[0032] like Figure 1 As shown, the lid 13 of the waste liquid recycling bin is hemispherical in shape, smoothly transitioning to the top of the bin body. The diameter of the lid 13 is the same as the diameter of the bin body, ensuring a perfect fit with the opening and forming a complete sealed structure. The lid 13 is located at the top of the waste liquid recycling bin and is hinged to the bin body, opening and closing via a flip-top mechanism.

[0033] like Figure 2-3 As shown, the opening device includes a first working box, and a first communicating vessel 1, a first float 2, a first slide rail 3, and a first spring 4 (elastic coefficient range: 1.99 × 10⁻⁶) disposed within the first working box. 6 N / m - 2.78 × 10 6 N / m), first disc spring 5, gear D6, eccentric gear E7 and gear F8.

[0034] One end of the first communicating vessel 1 is installed through the first working box and is movably connected to the inner wall of the first working box, so that the first communicating vessel 1 can slide relative to the first working box when compressed. The area of ​​the first float 3 is S, the depth of the detected position is h, and it can provide a force of ρghs to the first spring 4. The spring compression is l, the spring constant is k, and the required force of the spring is kl. As long as ρghs ≥ kl, the first spring can generate sufficient compression to release the gear D. h can be measured, the spring compression l is 3 mm, and the required elastic constant can be selected to make the first float 3 slide relative to the first working box. A spring generates sufficient compression to release gear D; a first float 2 is connected to a first spring 4; the first spring 4 is positioned above the first communicating vessel 1, with one end connected to the inner wall of the first working box and the other end in contact with gear D6; gear D6 is positioned on the first disc spring 5, and is locked and constrained by the first spring 4 and the first float 2; an eccentric gear E7 is positioned above gear D6 and meshes with gear D6, and gear F8 is positioned above eccentric gear E7 and meshes with eccentric gear E7, used to transmit power.

[0035] In this embodiment, the first float 2 is a snap-fit ​​type, the first float 2 is disposed on the first communicating vessel 1, the first float 2 is slidably disposed on the first slide rail 3, the first slide rail 3 provides the range of movement of the first float 2; the first float 2 is in contact with the movable end of the first spring 4 (the two are fixedly connected, or the two are in contact).

[0036] In this embodiment, the first drive shaft 9 of gear F8 is connected to the pin 10. The operation of gear F8 causes the pin 10 connected to the first drive shaft 9 of gear F8 to rotate, thereby opening the bucket lid.

[0037] In this embodiment, the first float 2 fixes the gear D6 under the action of the first spring 4, and the first spring 4 keeps the gear D6 in the initial position; the first disc spring 5 is in a compressed state in the initial state and stores energy.

[0038] Depth sensing and spring compression: When the waste liquid recycling tank sinks to a certain depth, the pressure of the surrounding water applies pressure to the first spring 4 in the first working box through the first communicating vessel 1 and the first float 2, causing the first spring 4 to generate a certain amount of compression; when the first spring 4 in the first working box is compressed to a degree sufficient to release the constraint on gear D6, the first disc spring 5 is released, driving gear D6 to rotate, gear D6 drives eccentric gear E7 to rotate, eccentric gear E7 transmits to gear F8, and then drives pin 10 through the transmission shaft 9 of gear F8 to realize the opening operation of the waste liquid recycling tank lid.

[0039] like Figure 2As shown, the closing device includes a second working box, and a second communicating vessel 11, a second float 21, a second slide rail 31, and a second spring 41 (elastic coefficient range: 3.18 × 10⁻⁶) disposed within the second working box. 6 N / m - 3.98 × 10 6 N / m), second disc spring 51, gear A61, gear B71, gear C81.

[0040] The second communicating vessel 11 is mounted through the second working box at one end and is movably connected to the inner wall of the second working box, so that the second communicating vessel 11 can slide relative to the second working box when it is pressed. The second float 21 is connected to the second spring 41. The second spring 41 is located above the second communicating vessel 11, and one end of the second spring 41 is connected to the inner wall of the second working box, and the other end is connected to the gear A61. The gear A61 is mounted on the second disc spring 51, and the gear A61 is locked and constrained by the second spring 41 and the second float 21. The gear B71 is located above the gear A61 and meshes with the gear A61. The gear C81 is located above the gear B71 and meshes with the gear B71, and is used to transmit power.

[0041] In this embodiment, the second float 21 is a snap-fit ​​type, the second float 21 is disposed on the second communicating vessel 11, the second float 21 is slidably disposed on the second slide rail 31, the second slide rail 31 provides the range of movement of the second float 21; the second float 21 is in contact with the movable end of the second spring 41 (the two are fixedly connected, or the two are in contact).

[0042] In this embodiment, the second drive shaft 91 of gear C81 is connected to the pin 10. The operation of gear C81 causes the pin 10 connected to the second drive shaft 91 of gear C81 to rotate, thereby closing the lid.

[0043] In this embodiment, the second float 21 fixes the gear A61 under the action of the second spring 41, and the second spring 41 keeps the gear A61 in the initial position; the second disc spring 51 is in a compressed state in the initial state and stores energy.

[0044] The function of density sensing and the float: After the waste liquid recovery tank is full of waste liquid, the density of the surrounding water and waste liquid mixture increases. This density change causes the second communicating vessel 11 and the second float 21 in the second working box to be under greater pressure, thereby compressing the second spring 41 in the second working box to the extent required to release the constraint on gear D6. At this time, the second disc spring 51 in the second working box is released, driving gear A61 to rotate, and through the linkage of gears B71 and C81, the lid 13 of the waste liquid recovery tank is closed.

[0045] Because the spring in the first working chamber has a smaller spring constant, it responds to pressure changes earlier than the spring in the second working chamber. This design difference ensures the correct response of the device under specific conditions.

[0046] In this embodiment, the pin 10 is located at the edge of the waste liquid recycling tank lid 13 and is connected to the rotating arm of the waste liquid recycling tank lid 13 via a sleeve structure. The first drive shaft 9 of the first working box and the second drive shaft 91 of the second working box are both rigidly connected to the pin 10 via flanges. The first drive shaft 9 drives the pin 10 to rotate, and the rotating arm on the waste liquid recycling tank lid 13 transmits power through the sleeve structure, rotating 90 degrees clockwise to open the waste liquid recycling tank lid 13, allowing waste liquid to enter the recycling tank. When the waste liquid recycling tank is full, the second drive shaft 91 drives the pin 10 to rotate, and the rotating arm on the waste liquid recycling tank lid 13 transmits power through the sleeve structure, rotating 90 degrees counterclockwise to close the waste liquid recycling tank lid 13.

[0047] In this embodiment, eccentric holes 12 are provided on both eccentric gear E7 and gear B71. The eccentric holes 12 allow gear D6 to transmit power to eccentric gear E7, while gear F8 cannot transmit power to eccentric gear E7; and allow gear A61 to transmit power to gear B71, while gear C81 cannot transmit power to gear B71; thus maintaining the unidirectional motion and stability of the system, ensuring the accuracy of operation and the reliability of the system.

[0048] The working principle or usage process of the device of the present invention is as follows: In the initial state, the first float 2, together with the first spring 4, fixes the gear D6; when the waste liquid recovery tank and the first working box sink to a certain depth, the first communicating vessel 1 is subjected to the pressure of the surrounding water, and the first float 2 applies pressure to the first spring 4, causing the first spring 4 to generate a certain amount of compression and the first float 2 to be displaced in the first slide 3, that is, the first float 2 drives the first spring 4 away from the surface of the gear D; when the first spring 4 of the first working box is compressed to a degree sufficient to release the constraint on the gear D6, the first disc spring 5 is released, driving the gear D6 to rotate, the gear D6 drives the eccentric gear E7 to rotate, the eccentric gear E7 transmits to the gear F8, and then drives the pin 10 connected to it through the first transmission shaft 9 of the gear F8. The rotating arm on the cover 13 of the waste liquid recovery tank transmits power through the sleeve structure and rotates 90 degrees clockwise to open the cover 13 of the waste liquid recovery tank, allowing the waste liquid to enter the recovery tank.

[0049] After the waste liquid recovery tank is filled with waste liquid, the density of the surrounding water and waste liquid mixture increases. The second communicating vessel 11 is subjected to greater pressure from the surrounding water and waste liquid mixture. This pressure causes the second float 21 in the second working box to compress the second spring 41 and displace the second float 21 in the second slide 31. Specifically, the second float 21 moves the second spring 41 away from the surface of gear A61, thus compressing the second spring 41 in the second working box to the extent necessary to release the constraint on gear A61. At this time, the second disc spring 51 in the second working box is released, causing gear A61 to rotate. Through the linkage of gears B71 and C81, the second transmission shaft 91 drives the pin 10 to rotate. The rotating arm on the waste liquid recovery tank lid 13 transmits power through the sleeve structure, rotating 90 degrees counterclockwise to close the waste liquid recovery tank lid 13.

[0050] The present invention also includes a method for collecting underwater waste liquid, employing the above-mentioned adaptive underwater waste liquid collection device, comprising the following steps:

[0051] S1: First, place the waste liquid recovery tank in water. When the waste liquid recovery tank sinks to the target area in the water, the spring in the first working box will be compressed and respond to perform the opening operation.

[0052] S11: The first communicating vessel 1 is subjected to water pressure, which causes the first spring 4 to be compressed through the first float 2, thereby releasing the constraint on the gear D6. At the same time, the first disc spring 5 is released and drives the gear D6 to rotate.

[0053] S12: Gear D6 is linked with eccentric gear E7 and gear F8. The first drive shaft 9 drives the pin 10 to rotate. The rotating arm on the waste liquid recycling tank cover 13 transmits power through the sleeve structure and rotates 90 degrees clockwise to open the waste liquid recycling tank cover 13, allowing waste liquid to enter the recycling tank.

[0054] S2: When the waste liquid recovery tank is full, the density of the surrounding water and waste liquid mixture increases, and the spring in the second working box responds to the pressure, thus performing the closing operation;

[0055] S21: The second communicating vessel 11 is subjected to the pressure of the surrounding water and waste liquid mixture. The second float 21 compresses the second spring 41, thereby releasing the constraint on the gear A61. At the same time, the second disc spring 51 is released and drives the gear A61 to rotate.

[0056] S22: Gear A61 is linked with gears B71 and C81. The second drive shaft 91 drives the pin 10 to rotate. The rotating arm on the waste liquid recovery tank cover 13 transmits power through the sleeve structure and rotates 90 degrees counterclockwise to close the waste liquid recovery tank cover 13.

[0057] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
