Furthermore, caisson pressurization improves the stability of the caisson during the sinking process, ensuring smooth construction and reliable project quality.

[0003] Currently, the construction involves too many workers and the marine environment is harsh, so there are certain risks involved in offshore construction, which may pose certain risks to the construction workers. In addition, the presence of garbage in the seawater will also have a certain impact on the pressurization operation. Therefore, this utility model proposes a caisson pressurization device.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-7 As shown, a caisson depressurization device includes a caisson 1 with multiple water inlets 2 installed on it. Depressurization components are installed on the water inlets 2. The depressurization components include a connecting pipe 4 for water inlet and a pipe connector 5 for connecting the connecting pipe 4. The connecting pipe 4 and the pipe connector 5 are fixedly connected. A waterproof box 3 is installed on the pipe connector 5. The connecting pipe 4 is connected to the water inlet 2. A water inlet unit 6 is installed inside the waterproof box 3. The water inlet unit 6 includes a scraping component for cleaning and an opening and closing component for controlling the water inlet in the connecting pipe 4.

[0021] The scraping assembly includes a scraper 601 and a filter element 603. The filter element 603 is fixedly installed inside the connecting pipe 4 and has multiple filter holes 604. The scraper 601 contacts the filter element 603 and is connected to the connecting pipe 4. The scraping assembly also includes a mounting shell 605, which is fixedly installed inside the waterproof box 3. A motor 606 is fixedly installed on the mounting shell 605, and a lead screw 611 is fixedly installed on the output end of the motor 606. The scraping assembly also includes a connecting plate 607, which is threadedly engaged with the lead screw 611 and connected to the scraper 601. The scraper 601 scrapes the filter element 603, causing some debris blocked on the rotating plate 602 to be scraped off, ensuring the efficiency of water intake.

[0022] The opening and closing assembly includes a rotating plate 602, which is connected to the connecting pipe 4. A gear 610 is fixedly installed on the rotating plate 602. The opening and closing assembly also includes a motor 608, which is fixedly installed inside the waterproof box 3. A gear 609 is fixedly installed on the output end of the motor 608. The gear 609 meshes with the gear 610. By rotating the rotating plate 602, the rotating plate 602 can be deflected at an angle, thereby further controlling the water inlet speed in the connecting pipe 4.

[0023] The connecting pipe 4 is provided with a through hole 401 and a connecting hole 402. The rotating plate 602 is connected to the scraper 601, and the connecting hole 402 is connected to the rotating plate 602. The scraper 601 slides in the through hole 401, and the rotating plate 602 rotates in the connecting hole 402.

[0024] Working principle: When the caisson sinks below the water surface and reaches the designated pressure water height, motor 2 (608) is started. The output of motor 2 (608) drives gear 2 (610) to rotate via gear 1 (609). Gear 2 (610) drives rotating plate 602 to rotate within connecting hole 402. At this time, rotating plate 602 shifts in angle. Water passes through connecting pipe 4 and is filtered by filter element 603. Then, it enters inlet 2 through rotating plate 602 and flows into the caisson. Once the pressure water height of the caisson reaches the stable draft requirement, motor 2 (608) is started. When 608 is reversed, the rotating plate 602 fits perfectly with the connecting pipe 4, preventing water from passing through. When water enters, debris enters the connecting pipe 4 and blocks the filter holes 604 on the filter element 603. At this time, motor 606 is started. The output end of motor 606 drives the lead screw 611 to rotate. The lead screw 611 drives the scraper 601 through the connecting plate 607 to scrape the filter element 603, ensuring the cleanliness of the filter element 603 and further ensuring the speed of water intake. After scraping, motor 606 is reversed, and the connecting plate 607 drives the scraper 601 to reset.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
