It should be understood that these examples are only used to illustrate the present invention and are not used 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 has a main structure including a cover opening device and a cover closing device connected to the waste liquid recovery barrel cover 13; the cover opening device and the cover closing device are activated by utilizing the pressure and density changes of water to automatically open and close the waste liquid recovery barrel cover 13.

[0031] In this embodiment, the waste liquid recovery barrel adopts a cylindrical design and is an existing commercially available product.

[0033] like Figure 2-3 As shown, the cover opening device includes a first working box, and a first communicating vessel 1, a first floating block 2, a first slideway 3, and a first spring 4 (elastic coefficient range: 1.99×10 6 N / m-2.78×10 6 N / m), first coil spring 5, gear D6, eccentric gear E7 and gear F8.

[0034] One end of the first communicating vessel 1 is penetrated and arranged on the first working box, and is movably connected with the inner wall of the first working box, so that the first communicating vessel 1 can slide relative to the first working box when under pressure. The area of ​​the first floating block 3 is S. When the depth of the position to be collected is detected to be h, a force of ρghs can be provided to the first spring 4. The spring compression amount is l, and the spring coefficient is k. At this time, the required force of the spring is kl. Only ρghs≥kl can make the first spring produce enough compression to release the gear D. h can be measured. The spring compression amount l is 3 mm. By selecting the required elastic coefficient, the first A spring generates enough compression to release gear D; the first floating block 2 is connected to the first spring 4; the first spring 4 is arranged above the first communicating vessel 1, and one end of the first spring 4 is connected to the inner wall of the first working box, and the other end is in contact with gear D6; gear D6 is arranged on the first disc spring 5, and the gear D6 is locked and constrained by the first spring 4 and the first floating block 2; the eccentric gear E7 is arranged above the gear D6 and meshes with the gear D6, and the gear F8 is arranged above the eccentric gear E7 and meshes with the eccentric gear E7 for transmitting power.

[0035] In this embodiment, the first floating block 2 is of a snap-on type, the first floating block 2 is arranged on the first communicating vessel 1, the first floating block 2 is slidably arranged on the first slide 3, and the first slide 3 provides a range of movement for the first floating block 2; the first floating block 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 transmission shaft 9 of the gear F8 is connected to the latch 10. Through the operation of the gear F8, the latch 10 connected to the first transmission shaft 9 of the gear F8 is rotated to open the barrel cover.

[0037] In this embodiment, the first floating block 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 coil spring 5 is in a compressed state in the initial state to store energy.

[0038] Depth sensing and spring compression: When the waste liquid recovery barrel 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 floating block 2, causing the first spring 4 to produce a certain amount of compression; 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 coil spring 5 is released, driving the gear D6 to rotate, and the gear D6 drives the eccentric gear E7 to rotate, and the eccentric gear E7 is transmitted to the gear F8, and then the latch 10 is driven through the transmission shaft 9 of the gear F8 to realize the opening operation of the lid of the waste liquid recovery barrel.

[0039] like Figure 2As shown, the cover closing device includes a second working box, and a second connecting vessel 11, a second floating block 21, a second slideway 31, and a second spring 41 (elastic coefficient range: 3.18×10 6 N / m-3.98×10 6 N / m), second coil spring 51, gear A61, gear B71, gear C81.

[0040] One end of the second communicating vessel 11 is penetrated and arranged on the second working box, and is movably connected with the inner wall of the second working box, so that the second communicating vessel 11 can slide relative to the second working box when pressurized, and the second floating block 21 is connected with the second spring 41; the second spring 41 is arranged above the second communicating vessel 11, and one end of the second spring 41 is connected with the inner wall of the second working box, and the other end is connected with the gear A61; the gear A61 is arranged on the second disc spring 51, and the gear A61 is locked and constrained by the second spring 41 and the second floating block 21; the gear B71 is arranged above the gear A61 and meshes with the gear A61, and the gear C81 is arranged above the gear B71 and meshes with the gear B71, for transmitting power.

[0041] In this embodiment, the second float 21 is a snap-on type, the second float 21 is arranged on the second communicating vessel 11, the second float 21 is slidably arranged on the second slide 31, and the second slide 31 provides a range of movement for 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 transmission shaft 91 of the gear C81 is connected to the latch 10. Through the operation of the gear C81, the latch 10 connected to the second transmission shaft 91 of the gear C81 is rotated to achieve the closing of the barrel cover.

[0043] In this embodiment, the second floating block 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 coil spring 51 is in a compressed state in the initial state to store energy.

[0044] Function of density sensing and floating block: After the waste liquid recovery barrel is filled with 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 floating block 21 in the second working box to be subjected to greater pressure, so that the second spring 41 in the second working box is compressed to the extent required to release the constraint on the gear D6. At this time, the second coil spring 51 of the second working box is released, driving the gear A61 to rotate and realize the closing operation of the waste liquid recovery barrel cover 13 through the linkage of the gear B71 and the gear C81.

[0045] Since the spring in the first chamber has a smaller spring rate, it responds to pressure changes earlier than the spring in the second chamber. This design difference ensures that the device reacts correctly under certain conditions.

[0046] In this embodiment, the latch 10 is located at the edge of the waste liquid recovery barrel lid 13, and is connected to the rotating arm of the waste liquid recovery barrel lid 13 through a sleeve structure. The first transmission shaft 9 of the first working box, the second transmission shaft 91 of the second working box and the latch 10 are rigidly connected by flanges. The first transmission shaft 9 drives the latch 10 to rotate, and the rotating arm on the waste liquid recovery barrel lid 13 transmits power through the sleeve structure and rotates 90 degrees clockwise to open the waste liquid recovery barrel lid 13 and allow waste liquid to enter the recovery barrel. When the waste liquid recovery barrel is full, the second transmission shaft 91 drives the latch 10 to rotate, and the rotating arm on the waste liquid recovery barrel lid 13 transmits power through the sleeve structure and rotates 90 degrees counterclockwise to close the waste liquid recovery barrel lid 13.

[0047] In this embodiment, an eccentric hole 12 is provided on both the eccentric gear E7 and the gear B71. The eccentric hole 12 enables the gear D6 to transmit power to the eccentric gear E7, while the gear F8 cannot transmit power to the eccentric gear E7; enables the gear A61 to transmit power to the gear B71, while the gear C81 cannot transmit power to the gear B71; maintains the unidirectional movement and stability of the system, and ensures the accuracy of the operation and the reliability of the system.

[0048] The working principle or use process of the device of the present invention is as follows: in the initial state, the first floating block 2 cooperates with the first spring 4 to fix the gear D6; when the waste liquid recovery barrel 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 floating block 2 applies pressure to the first spring 4, resulting in a certain amount of compression of the first spring 4 and displacement of the first floating block 2 on the first slide 3, that is, the first floating block 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 coil spring 5 is released, driving the gear D6 to rotate, the gear D6 drives the eccentric gear E7 to rotate, the eccentric gear E7 is transmitted to the gear F8, and then the first transmission shaft 9 of the gear F8 drives the pin 10 connected thereto, the rotating arm on the waste liquid recovery barrel cover 13 transmits power through the sleeve structure, and rotates 90 degrees clockwise to open the waste liquid recovery barrel cover 13, allowing the waste liquid to enter the recovery barrel.

[0049] After the waste liquid recovery barrel is filled with waste liquid, the density of the surrounding water and waste liquid mixture increases. The second communicating vessel 11 is subjected to a greater pressure of the surrounding water and waste liquid mixture, and the second floating block 21 in the second working box causes the second spring 41 to produce a certain amount of compression and the second floating block 21 to produce displacement in the second slide 31, that is, the second floating block 21 drives the second spring 41 away from the surface of the gear A61; so that the compression amount of the second spring 41 in the second working box reaches the required degree to release the constraint on the gear A61. At this time, the second coil spring 51 of the second working box is released, driving the gear A61 to rotate and through the linkage of the gear B71 and the gear C81, the second transmission shaft 91 drives the latch 10 to rotate, and the rotating arm on the waste liquid recovery barrel cover 13 transmits power through the sleeve structure, and rotates 90 degrees counterclockwise to realize the closing operation of the waste liquid recovery barrel cover 13.

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

[0051] S1: First, place the waste liquid recovery barrel in water. When the waste liquid recovery barrel sinks to the target area in the water, the spring in the first working box is first compressed and responds, and the cover opening operation is performed;

[0052] S11: The first communicating vessel 1 is subjected to water pressure, which compresses the first spring 4 through the first floating block 2 to release the constraint on the gear D6. At the same time, the first coil spring 5 is released and drives the gear D6 to rotate;

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

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

[0055] S21: The second communicating vessel 11 is subjected to the pressure of the surrounding water and waste liquid mixture, and the second spring 41 is compressed through the second floating block 21, thereby releasing the constraint on the gear A61, and at the same time, the second coil spring 51 is released and drives the gear A61 to rotate;

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