Description

Technical Field

[0001] The utility model relates to the technical field of a port tugboat refueling system, in particular to a novel port tugboat intermediate refueling station device. Background Art

[0002] The fuel filling ports of harbor tugboats are basically on the port and starboard sides of the ship. Usually, when a ship is refueled, it will be on one side. Figure 1 During the fuel filling process, the left and right fuel tanks on the ship are filled by adjusting the opening of the left fuel tank inlet valve and the right fuel tank inlet valve.

[0003] The existing refueling device has the following disadvantages: First, the fuel is added on one side of the ship. Once a fuel leak occurs, the pressure of the fuel refueling pipeline is relatively high. Due to the close proximity to the sea and the untimely treatment of oil spills, it is easy to cause marine pollution accidents;

[0004] Second, during the fuel filling process, the staff needs to measure the liquid levels of the left and right tanks at any time, and control the refueling volume of the left and right fuel tanks by adjusting the opening of the left and right fuel tank inlet valves, which makes the fuel filling work inconvenient;

[0005] Third, the fuel supply pump pressures of refueling ships are different. If the fuel supply pressure is too high, the pressure at the connecting flange will be too high during the fuel filling process, which may easily cause the risk of fuel leakage.

[0006] Therefore, a new intermediate refueling station device for harbor tugboats is proposed to solve the above problems. Utility Model Content

[0007] In view of the above existing technical problems, the utility model provides a novel intermediate filling station device for port tugboats, characterized in that it includes an oil receiving pan, a refueling main pipe, an overflow pipe, a pressure solenoid valve, an overflow tank, a liquid level remote control solenoid valve, a left fuel tank, a right fuel tank, and a high-level relay. The oil receiving pan is arranged at the bottom of the fuel filling port, the fuel filling port is connected to one end of the refueling main pipe, the other end of the refueling main pipe is respectively connected to two refueling branch pipes through a three-way valve, and a liquid level remote control solenoid valve is installed on the pipelines of the two refueling branch pipes. One of the refueling branch pipes is connected to the left fuel tank, and the other refueling branch pipe is connected to the right fuel tank. High-level relays are respectively installed on the left fuel tank and the right fuel tank, the branch outlet arranged on the refueling main pipe is connected to the overflow pipe, the overflow pipe is connected to the overflow tank, and the pressure solenoid valve is installed on the overflow pipe.

[0008] The fuel filling port is arranged at the middle position of the rear deck.

[0009] Beneficial effects of the utility model:

[0010] The utility model sets an intermediate filling station in the middle of the rear deck. Compared with the original setting on one side of the ship, the staff can handle the leakage in time, and an oil receiving pan is set at the bottom of the fuel filling port. Once a fuel leak occurs, the set oil receiving pan can store the leaked fuel, reducing the risk of marine environmental pollution.

[0011] The utility model arranges high-level relays on the left and right fuel tanks and installs a liquid level remote control solenoid valve on the refueling branch pipe. When the oil level in the fuel tank reaches the position of the high-level relay, an alarm is triggered and the corresponding liquid level remote control solenoid valve is closed to block the addition of fuel, thereby realizing automatic control of the refueling amount of the left and right fuel tanks and reducing the workload of the staff.

[0012] The utility model provides a branch outlet on the refueling main pipe and connects it to the overflow chamber through an overflow pipe, and a pressure solenoid valve is installed on the overflow pipe. When the oil supply pressure is large and exceeds the set limit of the pressure solenoid valve, the pressure solenoid valve opens, and a part of the fuel flows to the overflow chamber for pressure relief, which effectively reduces the risk of leakage caused by excessive pressure when refueling.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1

[0020] like Figure 2 As shown, the fuel filling port 101 is arranged in the middle of the tail frame plate 100, and an oil receiving pan 1 is arranged at the bottom of the fuel filling port 101. Once a fuel leak is found, compared with the original filling port arranged on one side of the ship, the staff can handle the leak in time, and the arranged oil receiving pan 1 can store the leaked fuel, thereby reducing the risk of marine environmental pollution;

[0021] The fuel filling port 101 is connected to one end of the fuel filling main pipe 2. The branch outlet arranged on the fuel filling main pipe 2 is connected to the overflow chamber 8 through the overflow pipe 7. A pressure solenoid valve 9 is installed on the overflow pipe 7. When the fuel supply pressure is relatively high and exceeds the set limit of the pressure solenoid valve 9, the pressure solenoid valve 9 opens, and a part of the fuel flows into the overflow chamber 8 through the overflow pipe 7 to achieve pressure relief, thereby effectively reducing the risk of leakage caused by excessive pressure when fuel is added.

[0022] The main refueling pipe 2 is connected to two refueling branch pipes 3 through a three-way valve, one of which is connected to the left fuel tank 41, and the other is connected to the right fuel tank 42. Liquid level remote control solenoid valves 5 are installed on the pipelines of the two refueling branch pipes 3, and high-level relays 6 are installed on the left fuel tank 41 and the right fuel tank 42. When the tugboat is adding fuel, the fuel enters the left fuel tank 41 and the right fuel tank 42 respectively through the main refueling pipe 2 and the refueling branch pipe 3. When the high-level relays 6 set on the left fuel tank 41 and the right fuel tank 42 trigger an alarm, the liquid level remote control solenoid valves 5 on the corresponding pipelines are closed to block the addition of fuel, thereby realizing automatic control of the refueling amount of the left and right fuel tanks and automatic filling of the fuel tanks, thereby reducing the workload of the staff.

[0023] It should be noted that:

[0024] The high-level relay 6 in this application belongs to a liquid level relay. The liquid level relay monitors the liquid level and automatically triggers a switch when the liquid level reaches or exceeds a preset value, thereby controlling the liquid level. The liquid level relay usually includes a sensor and a relay. The sensor is responsible for monitoring the liquid level and converting it into an electrical signal and sending it to the relay. The relay connects or disconnects the circuit according to the received signal to control the operation or stop of the equipment.

[0025] The pressure solenoid valve of the present application belongs to a pressure control solenoid valve, which is an automatic control device for adjusting the pressure of a fluid medium, and can accurately and stably control the pressure of the conveyed fluid medium.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
