Description

Technical Field

[0001] This invention belongs to the field of sanitary treatment equipment technology, and specifically relates to a sanitary system for diving. Background Technology

[0002] With the development of diving technology, diving equipment (such as submersibles, submarines, and underwater workstations) is increasingly widely used in marine exploration, military operations, and commercial activities. In the confined diving environment, the reliability and safety of the sanitation system directly affect personnel health and mission efficiency. Traditional diving sanitation systems suffer from the following technical shortcomings:

[0003] Low treatment efficiency: Wastewater and excrement need to be collected manually or rely on simple filtration devices, which can easily cause blockages or pollution.

[0004] Insufficient automation: Relying on manual monitoring and operation, it is difficult to adapt to the needs of long-duration diving missions.

[0005] Space constraints: Traditional systems have a loose structure, occupying limited space inside the cabin and affecting equipment layout and personnel activities.

[0006] Environmental risks: Direct discharge of untreated wastewater may damage marine ecosystems or cause odors and bacterial growth due to poor circulation in enclosed environments.

[0007] To address the above problems, the present invention provides a sanitary system for diving. Summary of the Invention

Both the gear 2 and the gear 3 are rotatably installed on the filter box, and the gear 3 is fixedly connected to the rotating shaft.

[0017] Furthermore, the filtration mechanism also includes two baffles, which are installed on both sides of the connecting frame. The connecting frame is fixedly connected to the rotating shaft. When the rotating shaft drives the connecting frame to rotate, one baffle coincides with a collection hole on the filter box, and the other baffle does not overlap with another collection hole.

[0018] Furthermore, the filtration mechanism also includes two cleaning rollers, which are slidably engaged with two filter plates respectively. A sliding rod is fixedly installed on each cleaning roller, and the sliding rod is slidably engaged with a guide rod. The guide rod is fixedly installed on the filter box, and a return spring is provided between the guide rod and the filter box. A lever is provided between the two cleaning rollers, and the lever is fixedly installed on the output shaft of the second motor.

[0019] Furthermore, the sliding plate is provided with a plurality of through holes arranged in a circle. A lower ring is rotatably installed above the through holes. The lower ring is fixedly connected to the upper ring and communicates with the upper ring. The lower ring is provided with a circular hole corresponding to the through hole. A movable rod is fixedly installed on the upper ring. A threaded block is provided on the movable rod. A ball head rod that can form a threaded engagement with the threaded block is provided above the threaded block. The ball head rod is fixedly installed inside the upper part of the discharge box.

[0020] Furthermore, the emission mechanism also includes two sets of symmetrically arranged push rods. Each set of push rods includes two push rods. One end of each set of two push rods is rotatably connected to a sliding plate, and the other end is rotatably connected to a drive block. The two drive blocks are slidably mounted on a long rod. The long rod is fixedly mounted inside the emission box. Two symmetrically arranged drive rods are arranged between the two long rods. The drive rods are provided with bosses. A return spring is provided between the drive block, the boss, and the emission box. One end of an L-shaped rod is fixedly mounted on the drive rod, and the other end of the L-shaped rod is slidably engaged with the emission bucket.

[0021] Furthermore, the discharge mechanism also includes a water tank, which is fixedly installed above the discharge box, and the outlet of the water tank is connected to the movable rod.

[0022] The beneficial effects of this invention compared with the prior art are: (1) This invention completes the collection and discharge of waste through the crushing mechanism, the filtering mechanism and the discharge mechanism, and can collect waste for centralized treatment, which not only solves the hygiene problem of the staff during the diving operation, but also protects the underwater environment; (2) By setting up the filtering mechanism, this invention can store the crushed waste with smaller volume in the discharge box, and can also collect the waste that is not completely crushed in the collection box, which improves the filtration efficiency and ensures the cleanliness of the environment; (3) During the process of collecting waste in the discharge box, it can prevent waste from entering the water environment at will and polluting the water source, which plays a protective role for the environment.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example: Figure 1 — Figure 12 A sanitary system for diving, as shown, includes:

[0038] Processing box 1, with toilet 2 installed on processing box 1;

[0039] like Figure 1As shown, toilet 2 is a place for personnel to relieve themselves in the cabin. During the installation process, toilet 2 is placed above the plane, and the treatment box 1 is installed below the plane. The plane refers to a structure with a layered function, such as the floor or partition in the cabin. The purpose of this is to ensure that the process of treating sewage does not occur in the environment where people are.

[0040] Crushing mechanism 3 includes crushing rod 302, which is used to crush waste.

[0041] The crushing mechanism 3 also includes multiple crushing discs 303, which are mounted on the crushing rod 302. The crushing rod 302 is fixedly connected to the output shaft of the motor 301. The motor 301 is fixedly installed inside the processing box 1, and the crushing rod 302 is located inside the filter box 402.

[0042] like Figure 1 —— Figure 3 As shown, the crushing rod 302 is located in the vertical section connecting the pipe 401 and the toilet 2. The crushing rod 302 and the pipe 401 rotate together. When the staff finishes using the toilet and the toilet 2 is flushed, the motor 301 is started. The motor 301 drives the crushing rod 302 and the crushing discs 303 on the crushing rod 302 to stir and crush the sewage entering the pipe 401, so that the crushed sewage enters the filter box 402 through the pipe 401. There are two pipes 401 connected to the filter box 402. One pipe is located above the filter box 402 and connects to the toilet 2, and the other pipe 401 is located below the filter box 402 and connects to the inside of the discharge box 501.

[0043] The filter mechanism 4 is located inside the processing box 1. The filter mechanism 4 includes a filter box 402 fixedly installed on the processing box 1. The filter box 402 is connected to the toilet 2 through a pipe 401. Two filter plates 411 are provided inside the filter box 402. Multiple through holes 412 are provided on the filter plates 411. The filter plates 411 are fixedly connected to the filter box 402.

[0044] The filter mechanism 4 also includes a separation plate 410, which is located between two filter plates 411. The separation plate 410 is fixedly mounted on a rotating shaft 409, which is rotatably engaged with the filter plates 411. The rotating shaft 409 is connected to a power source for transmission.

[0045] The filter box 402 is provided with two collection holes 403, and a collection box 404 is provided outside the collection holes 403. The collection box 404 is detachably installed on the outside of the filter box 402. The filter box 402 is provided with two baffles 414 inside, which are used to block the separation plate 410.

[0046] The filter mechanism 4 also includes two baffles 413, which are installed on both sides of the connecting frame. The connecting frame is fixedly connected to the rotating shaft 409. When the rotating shaft 409 drives the connecting frame to rotate, one baffle 413 coincides with one collection hole 403 on the filter box 402, and the other baffle 413 does not overlap with the other collection hole 403.

[0047] like Figure 4 , Figure 7 , Figure 8 As shown, in the initial state, the separator 410 is in contact with a baffle 414 inside the filter box 402, so as to... Figure 8 From a specific perspective, when the separator plate 410 contacts the left-side baffle 414, the dirt that has entered the filter box 402 through the pipe 401 will fall onto the right-side filter plate 411. Figure 7 On the right-side filter plate 411, dirt is filtered through the through-hole 412, causing unbroken dirt to fall onto the filter plate 411. Since the separation plate 410 is in contact with the left-side baffle 414, dirt will not fall onto the left-side filter plate 411 at this time.

[0048] Furthermore, when the separating plate 410 contacts the left baffle 414, the left baffle 413 on the connecting frame overlaps with the left collection hole 403 on the filter box 402, and the right baffle 413 on the connecting frame does not overlap with the right collection hole 403 on the filter box 402. That is, the upper edge of the right baffle 413 is located at the lower edge of the collection hole 403. At the same time, the upper edge of the right filter plate 411 near the collection hole 403 is not lower than the lower edge of the collection hole 403. The purpose of this is that the collection box 404, which can be detachably installed outside the right collection hole 403 on the filter box 402, is connected to the inside of the filter box 402, which facilitates the subsequent cleaning of the dirt remaining on the filter plate 411.

[0049] The power source includes a second motor 405, which is fixedly installed on the outside of the filter box 402. The output shaft of the second motor 405 passes through the filter box 402 and is fixedly connected to a first gear 406 rotatably installed inside the filter box 402. The first gear 406 meshes with the second gear 407, and the second gear 407 meshes with the third gear 408. Both the second gear 407 and the third gear 408 are rotatably installed on the filter box 402. The third gear 408 is fixedly connected to the rotating shaft 409.

[0050] The filtration mechanism 4 also includes two cleaning rollers 416, which are slidably engaged with two filter plates 411 respectively. A sliding rod 417 is fixedly installed on the cleaning roller 416, and the sliding rod 417 is slidably engaged with a guide rod 418. The guide rod 418 is fixedly installed on the filter box 402, and a return spring 419 is provided between the guide rod 418 and the filter box 402. A lever 415 is provided between the two cleaning rollers 416, and the lever 415 is fixedly installed on the output shaft of the motor 405.

[0051] like Figure 4 —— Figure 8 As shown, when the separating plate 410 is positioned close to any of the baffles 414, the second motor 405, which is fixedly installed on the outside of the filter box 402, can be activated. This causes the output shaft of the second motor 405 to drive the first gear 406 and the lever 415 fixedly connected to the output shaft to rotate. When the first gear 406 rotates, since only a portion of its circumference has teeth, when that toothed portion rotates to mesh with the second gear 407, the second gear 407 will drive the third gear 408 to rotate. The rotating shaft 409 fixedly connected to the third gear 408 will then drive the separating plate 410 to rotate, causing the separating plate 410 to move closer to and contact a baffle 414. When the toothed portion of the first gear 406 leaves the second gear 407, the separating plate 410 contacts the baffle 414.

[0052] When a significant amount of residue remains on the filter plate 411 during filtration, the control center can restart motor 405. The output shaft of motor 405 drives gear 406 and lever 415 to rotate. Since the teeth on gear 406 have disengaged from gear 407, gears 407 and 408 cease rotation. The rotating lever 415 approaches sliding rod 417 and pushes it to slide on guide rod 418. Cleaning roller 416, fixedly connected to sliding rod 417, slides along the surface of filter plate 411, pushing the residue through collection hole 403 into collection box 404, thus cleaning the surface of filter plate 411 and preventing blockage of through hole 412. Furthermore, the collection box 404 improves the residue storage capacity. During underwater operations, to protect the environment, it is impossible to discharge and dispose of waste anytime and anywhere. Instead, the waste needs to be collected first. Therefore, some waste will enter the discharge tank 501 through the filter box 402, while some waste will enter the collection tank 404 through the collection hole 403. Of course, one-way valves are installed at the connections between pipe 401 and toilet 2, pipe 401 and filter box 402, and filter box 402 and discharge tank 501, ensuring the flow of gas and waste is from toilet 2 to filter box 402 and then to discharge tank 501. Alternatively, collection tank 404 can be filled with ionic compounds with disinfecting properties, such as silver ions or hypochlorite ions.

[0053] When one collection box 404 is full, motor 405 can be started, causing gear 406 to drive gear 3 408 to rotate through gear 407, thereby causing the separation plate 410 to switch to another baffle 414. At this time, the other collection hole 403 is no longer blocked by the baffle 413, and the dirt will be filtered through another filter plate 411. The dirt left on the surface of the filter plate 411 after filtration will be collected through another collection box 404.

[0054] The discharge mechanism 5 includes a discharge box 501 connected to the treatment box 1. A sliding plate 502 is slidably installed inside the discharge box 501, and a discharge bucket 516 is provided below the discharge box 501. The sliding plate 502 is provided with a plurality of circumferentially arranged through holes 503. A lower ring 505 is rotatably installed above the through holes 503. The lower ring 505 is fixedly connected to an upper ring 504 and communicates with the upper ring 504. The lower ring 505 is provided with a circular hole corresponding to the through holes 503. A moving rod 506 is fixedly installed on the upper ring 504. A threaded block 507 is provided on the moving rod 506. A ball head rod 508 that can form a threaded engagement with the threaded block 507 is provided above the threaded block 507. The ball head rod 508 is fixedly installed inside the upper part of the discharge box 501.

[0055] like Figure 1 , Figure 2 , Figure 9 —— Figure 12 As shown, after the waste is filtered by the filter plate 411, it enters the discharge box 501 through the pipe 401 below the filter box 402. Because the discharge bucket 516 is completely sealed below the two L-shaped rods 515, the waste can only be stored inside the discharge box 501. To prevent the spread of bacteria, silver ions, hypochlorite ions, etc. can be added to the discharge box 501 for sterilization and disinfection.

[0056] When the amount of waste inside the discharge box 501 reaches a certain volume (a pressure sensor can be installed to detect the pressure inside the discharge box 501), the gradually increasing waste will push the sliding plate 502 to slide upwards along the inside of the discharge box 501. In the initial state, the second through hole 503 does not coincide with the round hole below the lower ring 505, and the lower ring 505 will block the second through hole 503. Therefore, the waste in the discharge box 501 will not enter the upper ring 504 and the area above the discharge box 501 through the second through hole 503. When the threaded block 507 on the sliding plate 502 rises to contact the ball head rod 508, the threaded block 507 and the ball head rod 508 form a threaded engagement. At this time, during the rising process of the sliding plate 502, the threaded block 507 will drive the moving rod 506 to rotate on the water tank 517. That is, as the sliding plate 502 rises, the lower ring 505, the upper ring 504, and the moving rod 506 will rotate with the threaded block 507 until the circular hole on the lower ring 505 rotates to coincide with the second through hole 503. At this time, the threaded block 507 leaves the ball head rod 508, and the water tank 517 is activated. Water (which may contain hypochlorite ions) is supplied to the moving rod 506 through the water tank 517. The water enters the upper ring 504 and the lower ring 505 through the moving rod 506, and then enters the discharge tank 501, increasing the pressure in the discharge tank 501.

[0057] The emission mechanism 5 also includes two sets of symmetrically arranged push rods 509. Each set of push rods 509 includes two push rods 509. One end of each of the two push rods 509 is rotatably connected to the sliding plate 502, and the other end is rotatably connected to the drive block 513. The two drive blocks 513 are slidably mounted on the long rod 510. The long rod 510 is fixedly mounted inside the emission box 501. Two symmetrically arranged drive rods 512 are arranged between the two long rods 510. The drive rod 512 is provided with a boss 514. A return spring 511 is provided between the drive block 513, the boss 514 and the emission box 501. One end of an L-shaped rod 515 is fixedly mounted on the drive rod 512. The other end of the L-shaped rod 515 is slidably engaged with the emission bucket 516. The drive rod 512 is slidably engaged with the drive block 513. The discharge mechanism 5 also includes a water tank 517, which is fixedly installed above the discharge box 501, and the outlet of the water tank 517 is connected to the moving rod 506.

[0058] like Figure 1 , Figure 2 , Figure 9 —— Figure 12 As shown, during the initial upward movement of the sliding plate 502, the sliding plate 502 pushes the push rod 509 upward. The end of the push rod 509 away from the sliding plate 502 pushes the two drive blocks 513 to move away from each other along the long rod 510. When the threaded block 507 rotates upward and leaves the ball head rod 508, the drive block 513 has not yet contacted the boss 514 on the drive rod 512. As the sliding plate 502 continues to rise, the drive block 513 continues to move closer to the boss 514. When the drive block 513 contacts the boss 514, the drive block 513 will drive the two drive rods 512 to move away from each other on the discharge box 501 through the boss 514. Drive rod 512 moves L-shaped rod 515 away from discharge tank 516, causing the portion of L-shaped rod 515 extending into discharge tank 516 to gradually move away from discharge tank 516. This opens up the previously sealed interior of discharge tank 516, allowing waste inside discharge box 501 to be discharged through discharge tank 516. Water in water tank 517 then flushes and disinfects the interior of discharge box 501. It should be noted that other containers with collection functions can be connected to the outside of discharge tank 516. Alternatively, waste can be discharged when the submarine reaches a designated location, ensuring the waste is disposed of appropriately.

[0059] It should be noted that the start and stop of motor 301, motor 405, and water tank 517 in this invention can all be started by the control system. The control system includes a PLC controller, pressure sensor, etc. The control system belongs to the prior art, and the control system is not the main technical problem solved by this invention. Those skilled in the art can use it, and it will not be described in detail here.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
