Description

Technical Field

[0001] The present application relates to the technical field of marine biological prevention for ships, and in particular to a biological expelling device for a seabed door of a cabin. Background Art

[0002] A subsea gate is typically located on the side or outer plating of a ship below the waterline. It serves as a channel for pumping seawater or fresh water overboard. Water is pumped through the subsea gate into the seawater pipe and then into the various systems on the ship.

[0003] When a ship is operating at sea, the presence of organisms in the ocean, such as fish and seaweed, can easily increase the ship's resistance and reduce transmission, especially near the seabed gate. The pumping pipes at the seabed gate are easily infected by marine organisms and may even cause pipe blockage, affecting the smooth progress of the pumping operation. Summary of the Invention

[0004] In order to improve the intrusion of marine organisms on the seabed door, the present application provides a biological expelling device for the seabed door of the cabin.

[0005] This application provides a biological expelling device for a seabed door of a cabin, which adopts the following technical solution:

[0006] A biological expelling device for a seabed door of a cabin comprises a detector, an electronic expelling device and a controller. The detector and the electronic expelling device are both electrically connected to the controller and are both arranged at the seabed door of the cabin. The detector is used to detect whether there are biological organisms at the seabed door. The controller is used to obtain the detection result of the detector and activate the electronic expelling device when biological organisms are present at the seabed door. The electronic expelling device at least comprises a discharge expelling module for discharging.

[0007] By adopting the above technical solution, the detector and the electronic expeller are installed at the seabed gate. The detector is used to detect in real time whether there are any creatures at the seabed gate. If so, the controller will start the electronic expeller to expel the creatures. Specifically, the electronic expeller includes a discharge expulsion module. The discharge expulsion module drives away the creatures around the seabed gate by discharging, so as to reduce the intrusion of the seabed gate by marine organisms.

[0008] Preferably, it also includes a mounting assembly, which includes a turntable and a rotating member. The turntable is arranged on the inner wall of the seabed door opening. The rotating member is used to drive the turntable to rotate with the axis of the seabed door opening as the rotation center. The electronic expeller and detector are both arranged on the side of the turntable away from the cabin.

[0009] By adopting the above technical solution, the rotating member drives the turntable to rotate around the axis of the opening of the sea chest. Since the electronic repeller and the detector are installed on the turntable, the electronic repeller and the detector will rotate with the turntable and detect the entire circumferential environment of the sea chest during the rotation, expanding the detection range and optimizing the effect of repelling marine organisms.

[0010] Preferably, the turntable includes an inner disk and an outer disk magnetically adsorbed to each other. The inner disk is located inside the cabin, and the outer disk is located outside the cabin. The electronic repeller and the detector are arranged on the outer disk. The rotating member includes tooth blocks arranged along the circumference of the inner disk, a driving gear rotatably connected inside the cabin, and a motor for driving the driving gear to rotate. The driving gear is meshed with the tooth blocks. The opening of the sea chest is sealed, and the water inlet end of the water pump at the sea chest penetrates through the sea chest and is located outside the cabin.

[0011] By adopting the above technical solution, when the sea chest is closed, the water pump at the sea chest is located inside the cabin, and only the water inlet end of the water pump penetrates through the sea chest and is located outside the cabin. At this time, in order to realize the rotation of the turntable, the turntable is specifically divided into an inner disk and an outer disk magnetically adsorbed to each other. The rotating member is located inside the cabin and directly acts on the inner disk to realize the rotation of the inner disk. Since the outer disk is magnetically adsorbed to the inner disk, the outer disk will rotate under the action of the rotating inner disk and magnetic force, and then drive the electronic repeller and the detector to rotate circumferentially along the periphery of the water inlet pipe.

[0012] Preferably, the water inlet end of the water pump at the sea chest is communicated with a water inlet pipe. The marine organism repelling device further includes a filter screen arranged at the pipe orifice of the water inlet pipe and a cleaning assembly for cleaning the filter screen.

[0013] By adopting the above technical solution, the setting of the filter screen can intercept marine organisms, further reduce the intrusion of marine organisms, reduce the situation of marine organisms entering the water inlet pipe or even blocking the water inlet pipe, and ensure the smooth pumping work of the water pump.

[0014] Preferably, the turntable is located outside the water inlet pipe. The cleaning assembly includes a rotating rod, a scraping plate, and a linkage frame. The linkage frame is arranged on the lower surface of the turntable. The electronic repeller and the detector are arranged on the linkage frame. The rotating rod is located outside the turntable and is rotatably connected to the outer side wall of the cabin. The scraping plate is sleeved outside the rotating rod. A sliding hole for the end part of the linkage frame to slide is formed in the side wall of the scraping plate along its length direction. The linkage frame is used to rotate circumferentially with the turntable and drive the scraping plate to swing around the rotating rod at the same time. The scraping plate is used to be attached to the surface of the filter screen when swinging.

[0015] By adopting the above technical solution, when the turntable rotates, the linkage frame rotates together with the turntable to drive the electronic repeller and the detector to perform multi-directional detection. At the same time, since the linkage frame is inserted into the sliding hole and can slide along the length direction of the sliding hole, the linkage frame can also drive the scraper to swing around the rotating rod, so that the scraper is attached to the filter screen during the swinging process, realizing the cleaning of the filter screen.

[0016] Preferably, reinforcing ribs are provided on the side wall of the filter screen close to the inside of the water inlet pipe, and the peripheral wall of the reinforcing ribs is connected to the water inlet pipe.

[0017] By adopting the above technical solution, the setting of the reinforcing ribs can enhance the structural strength of the filter screen, so as to support the filter screen through the reinforcing ribs when the water pump starts pumping water, reducing the impact force of the water flow on the filter screen.

[0018] Preferably, a fixing rod is vertically arranged at the center of the reinforcing rib, the filter screen is movably sleeved on the fixing rod, and the filter screen is slidably connected to the fixing rod along the length direction of the fixing rod.

[0019] By adopting the above technical solution, when the water pump pumps water, the filter screen will move towards the direction close to the reinforcing rib under the impact of the water flow, realizing the sliding of the filter screen relative to the fixing rod. When there is no need to pump water, the filter screen will slide away from the reinforcing rib under the action of its own weight, promoting the exfoliation of the sundries on the filter screen through the sliding of the filter screen and optimizing the cleaning effect.

[0020] Preferably, the filter screen is rotatably connected to the side wall of the reinforcing rib, and the rotation center of the filter screen coincides with the center of the reinforcing rib. An elastic dial is provided on the side wall of the filter screen facing the scraper, and the elastic dial is located on the swinging path of the scraper.

[0021] By adopting the above technical solution, when the scraper swings around the rotating rod driven by the linkage frame, the scraper pushes against the elastic dial, so that the elastic dial drives the filter screen to deflect relative to the reinforcing rib, contributing to the exfoliation of the sundries attached to the filter screen and optimizing the cleaning effect.

[0022] Preferably, a docking rod is rotatably connected to the side wall of the scraper facing the filter screen, and the docking rod is used to be attached to the filter screen.

[0023] By adopting the above technical solution, the setting of the docking rod reduces the resistance when the scraper swings. At the same time, since the docking rod is in direct contact with the scraper, the rotation of the docking rod can reduce the retention of sundries on the docking rod, thereby affecting the subsequent cleaning effect of the docking rod on the filter screen.

[0024] Preferably, a plurality of guiding grooves are arranged along the circumferential direction of the peripheral wall of the docking rod far from the filter screen. The guiding grooves are distributed along the circumferential direction of the docking rod, and each guiding groove is arranged along the length direction of the docking rod.

[0025] By adopting the above technical solution, the provision of the guiding groove increases the contact area between the water flow and the docking rod. When the docking rod moves with the scraper, the water flow impacts the inner wall of the guiding groove to achieve the rotation of the docking rod.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Install the detector and the electronic expeller at the sea chest. The detector can detect in real time whether there are organisms at the sea chest. If so, the controller will activate the electronic expeller to expel the organisms. Specifically, the electronic expeller includes a discharge expelling module, and the discharge expelling module drives away the organisms around the sea chest by discharging, so as to reduce the intrusion of sea organisms on the sea chest.

[0028] 2. The rotating member drives the turntable to rotate around the axis of the sea chest opening. Since the electronic expeller and the detector are installed on the turntable, the electronic expeller and the detector will rotate with the turntable, and detect the entire circumferential environment of the sea chest during the rotation process, expanding the detection range and optimizing the expelling effect on sea organisms.

[0029] 3. The provision of the filter screen can intercept sea organisms, further reducing the intrusion of sea organisms, reducing the situation of sea organisms entering the water inlet pipe or even blocking the water inlet pipe, and ensuring the smooth pumping work of the water pump.
