[0002] Marine debris affects the marine landscape, threatens navigational safety, and impacts the health of marine ecosystems, thereby having a negative effect on the marine economy.
[0003] To intercept marine debris and gather it together for later salvage, multiple interconnected auxiliary tubes are typically set up on the sea surface to intercept floating objects. However, since existing tubes are hollow and can only float on the water, while they can intercept floating objects, they also obstruct passing ships and cause many inconveniences. Therefore, a floating debris interception device with a mid-section that can be opened and closed is needed. Utility Model Content

[0010] Furthermore, the water inlet is set at an angle.
[0011] Furthermore, the battery is fitted with a sealed casing.
[0012] The beneficial effects of this patent are:
[0013] This device uses a submersible pump installed inside the pontoon to draw seawater into the pontoon, increasing its weight and causing it to sink into the sea, creating a gap in the barrier and allowing ships to pass.
[0014] In addition, the device is equipped with a filter mechanism inside the water inlet pipe to prevent marine debris or phytoplankton from being drawn into the submersible pump and thus avoid damage to the submersible pump. Attached Figure Description

Detailed Implementation
[0021] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.
[0022] See Figure 1 , Figure 2 , Figure 3This is a schematic diagram of the structure of this patent. A mid-section openable and closable sea surface floating object blocking device includes a connecting pipe 1 and a float 2. Multiple floats 2 are provided and connected to each other through the connecting pipe 1. An installation seat 3 is installed in the inner cavity of the float 2. A submersible pump 4 is installed on the upper wall of the installation seat 3. One end of the water inlet pipe 5 is installed at the water inlet end of the submersible pump 4. The other end of the water inlet pipe 5 passes through the lower wall of the float 2. The output end of the submersible pump 4 is connected to the connecting pipe 1.
[0023] The submersible pump 4 can pump water from the outer ocean into the buoy 2, increasing the weight of the buoy 2 and causing multiple buoys 2 close to the submersible pump 4 to descend, thereby creating an opening in the arresting device to facilitate the entry and exit of ships.
[0024] At the same time, the submersible pump 4 in this device can also pump out the water in the float 2, so that the float 2 returns to its original weight and floats up, and the blocking device returns to the closed state.
[0025] In this paper, only one of the floats 2 located in the middle of the device is equipped with a photovoltaic panel 7, as well as an internal battery 8 and a submersible pump 4.
[0026] A filter mechanism 6 is inserted and installed inside the water inlet pipe 5. The filter mechanism 6 includes an insertion ring 61, a filter screen 62, a rotating rod 63, and a paddle 64. The insertion ring 61 is inserted and installed inside the water inlet pipe 5. The filter screen 62 is installed on the inner side wall of the insertion ring 61. The rotating rod 63 is inserted and installed in the middle of the filter screen 62. The paddle 64 is installed at the lower end of the rotating rod 63.
[0027] To prevent debris or plankton from entering the submersible pump 4, a filter screen 62 is installed in its inlet pipe 5 to filter the incoming water flow and prevent debris or plankton from getting tangled on the blades of the submersible pump 4, thus preventing damage to the submersible pump 4.
[0028] A photovoltaic panel 7 is installed on the upper wall of the float 2, and a storage battery 8 is installed in the inner cavity of the float 2. The photovoltaic panel 7 is electrically connected to the storage battery 8, and the storage battery 8 is electrically connected to the submersible pump 4.
[0029] The photovoltaic panel 7 can convert solar energy into electrical energy. The direct current generated will be stored in the battery 8 and then used to power the submersible pump 4.
[0030] Meanwhile, the submersible pump 4 proposed in this paper can be started by an external wireless controller, which eliminates the need for staff to swim to the device to start the submersible pump 4, making it very convenient.
[0031] The side wall of the float 2 has a through hole 9. The connecting pipe 1 is inserted into the inner cavity of the float 2. A limit ring 10 is installed at one end of the connecting pipe 1 inside the float 2. A sealing ring 11 is sleeved on the outside of the connecting pipe 1. The sealing ring 11 can fit against the inner wall of the through hole 9.
[0032] The setting of the limiting ring 10 can prevent the connecting pipe 1 from being pulled out of the float 2, while the sealing ring 11 can ensure the seal between the connecting pipe 1 and the float 2.
[0033] A shielding ring 12 is installed on the lower wall of the insertion ring 61. The shielding ring 12 is located on the outside of the blade 64. A water inlet hole 13 is opened on the side wall of the shielding ring 12.
[0034] The shielding ring 12 can prevent external debris from getting tangled on the outside of the blade 64. At the same time, when the submersible pump 4 is pumping water, the blade 64 can rotate under the drive of the water flow, and the blade 64 can scrape the filter screen 62 to prevent the filter screen 62 from being blocked.
[0035] The water inlet hole 13 is set at an angle;
[0036] The inclined water inlet 13 allows the water flow to push the blades 64 during pumping.
[0037] The battery 8 is fitted with a sealing casing 14.
[0038] The sealed casing 14 can prevent the battery 8 from coming into contact with external water, thus preventing damage to the battery 8.
[0039] When this patent is in operation, if it is necessary to open a gap in the device to allow ships to pass through smoothly, the staff controls the submersible pump 4 to start through the external controller, pumping water from the outer ocean into the buoy 2, increasing the weight of the buoy 2, causing multiple buoys 2 close to the submersible pump 4 to descend, thereby creating a gap in the barrier device to facilitate the entry and exit of ships.
[0040] Then, after the ship passes, the submersible pump 4 in this device pumps out the water in the buoy 2, restoring the buoy 2 to its original weight, causing it to float, and the arresting device returns to the closed state.
[0041] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent.
