Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to an anti-icing plug device for a ballast water tank. Background Art
[0002] The function of a ship's ballast water tank is to adjust the ship's heel, trim, draft, etc. by allocating ballast water. The role of ballast water is very important. When a ship actually sails to a high-latitude area, due to the low ambient temperature, such as below zero, the ballast water in the ballast water tank is easy to freeze. After freezing, the ballast water cannot circulate between the various compartments, and the meaning of adjusting the ship's navigation status by allocating ballast water is lost. In addition, for a fully loaded ballast tank, the expansion of the frozen ballast water volume will also cause structural damage to the cabin, affecting safe navigation. In response to the above problems, the inventor proposes an anti-icing plug device for a ballast water tank to solve the above problems. Utility Model Content
[0003] In order to solve the problem that the ship's ballast water tank is prone to ice formation when the water temperature is low, thus affecting the effective allocation of ballast water and the safe navigation of the ship; the purpose of the utility model is to provide an anti-icing plug device for a ballast water tank.
[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: an anti-icing plug device for a ballast water tank, comprising a cabin body, a hatch cover detachably provided on the top surface of the cabin body, a motor is provided above the hatch cover, an output shaft end of the motor is fixedly connected to an extension rod, an end of the extension rod away from the motor is fixedly connected to a first bevel gear, a second bevel gear is meshed with a side wall of the first bevel gear, a horizontal axis is inserted and fixedly connected to the middle of the side wall of the second bevel gear, a stirring paddle is fixedly sleeved on the side wall of the horizontal axis, a horizontal pipe is inserted and fixedly connected to the lower part of the side wall of the cabin body, a branch pipe is inserted and fixedly connected to the side wall of the horizontal pipe, the branch pipe is located in the cabin body, and a jet hole is penetrated through the side wall of the branch pipe.
[0005] Preferably, the side wall of the motor is provided with a fixed seat, the bottom surface of the fixed seat is fixedly connected to the top surface of the hatch cover, a water outlet pipe is inserted and fixedly connected to the lower part of the side wall of the cabin body, and a water inlet pipe is inserted and fixedly connected to one side of the top surface of the hatch cover, and the pipe openings of the water outlet pipe and the water inlet pipe are both provided with plugs. The motor is installed through the fixed seat. When the water temperature in the cabin is lower than zero degrees Celsius, the motor is started, and the extension rod will drive the first bevel gear to rotate under the action of the motor output shaft, so that the first bevel gear is meshed with the second bevel gear, and then the horizontal axis drives the stirring paddle to rotate, so that the water in the cabin can flow to avoid freezing.
[0006] Preferably, the top surface of the cabin cover is penetrated by an air vent, and the port of the air vent is provided with a dustproof net. When jet is sprayed in the cabin through the jet hole, exhaust can be discharged through the air vent to avoid excessive air pressure in the cabin. The dustproof net is used to prevent external dust from entering the cabin through the air vent. The side wall of the extension rod is rotatably connected to a concave plate, and the first bevel gear and the second bevel gear are both located in the concave opening of the concave plate. The side wall of the concave plate is fixedly connected to a transverse plate, and one end of the transverse plate away from the concave plate is fixed to the inner wall of the cabin, and one end of the transverse axis away from the second bevel gear extends into the cabin, and the transverse axis is rotatably connected to the cabin, and the concave plate is installed through the transverse plate. When the motor is started, the extension rod will drive the first bevel gear to rotate under the action of the motor output shaft, thereby making the first bevel gear mesh with the second bevel gear, and then the transverse axis drives the stirring paddle to rotate, so that the water in the cabin flows to avoid ice.
[0007] Preferably, a one-way valve is fixedly connected to the pipe end of the branch pipe, and the one-way valve is located outside the cabin. An air pipe connector is fixedly connected to the input end of the one-way valve, which connects the air pipe connector to an external air supply pipe, and supplies gas to the cross pipe through the air pipe connector. The gas enters the branch pipe and is then ejected through the jet holes, thereby generating bubbles in the cabin. During the rising process, the bubbles expand in volume and break near the liquid surface. The process of continuous rising, expansion and breaking of the gas can effectively alleviate the freezing condition of the ballast water. A support plate is provided on the side wall of the cross pipe, and the bottom surface of the support plate is fixedly connected to the inner bottom wall of the cabin.
[0008] Compared with the prior art, the beneficial effect of the utility model is that it can effectively prevent the ballast water in the cabin from freezing, thereby ensuring the effective allocation of ballast water and the safe navigation of the ship. When the water temperature in the cabin is below zero degrees Celsius, starting the motor can make the horizontal axis drive the stirring paddle to rotate, so that the water in the cabin can flow to avoid freezing. At the same time, gas can be supplied to the branch pipe through the horizontal pipe, and the gas is ejected through the jet hole, thereby generating bubbles in the cabin. In the process of the bubbles rising, the volume of the bubbles expands and breaks near the liquid surface. The freezing condition of the ballast water can be effectively alleviated by the continuous rising, expansion and breaking of the gas. BRIEF DESCRIPTION OF THE DRAWINGS
