Description

Technical Field

[0001] The invention relates to a marine weathertight shutter, and in particular to a marine weathertight shutter device and a control method. Background Art

[0002] With the development of the global shipping industry, ship container power supplies and ship battery compartments have become an important development direction for new energy power for small and medium-sized inland ships. Steel weatherproof shutters are used as ventilation and heat dissipation equipment for ship container power supplies and ship battery compartments. They are widely used in the ship field due to their advantages such as simple structure and installation. It is an inevitable trend for small and medium-sized inland ships to implement small cabin and large-capacity battery systems in the future. At present, most steel weatherproof shutters are directly welded to the vents of ship container power supplies and ship battery compartments, and the opening air volume cannot be automatically adjusted. When encountering severe weather such as storms, steel weatherproof shutters cannot detect whether rain has entered the cabin, and personnel need to check on site. However, the vents of some relatively important places, such as the emergency exhaust inlet and outlet of the battery compartment, the engine room vents, etc., consider the necessity of ventilation, and the ventilation system must be kept open.

[0003] How to improve the reliability of ventilation systems in important places such as ship container power supplies and ship battery compartments, and keep them open without being affected by bad weather, is a difficult point in ship ventilation design. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art such as the inability of the existing steel weathertight shutters to automatically adjust the opening air volume, the inability to detect whether rainwater has entered the cabin, and the vents of some relatively important places must be kept open. A marine weathertight shutter device and a control method are proposed. By configuring water pressure reducing dustproof cotton, a water leakage detection system, an electric control system, and a temperature measuring instrument, the problems such as the inability of the weathertight shutters to adjust the air volume, the inability to detect whether rainwater has entered the cabin, and the vents of some relatively important places must be kept open are effectively solved.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a marine weatherproof shutter device, including water pressure reducing dust-proof cotton, a water leakage detection system, an electric control system, and a temperature measuring instrument. The water leakage detection system is composed of a water leakage detection module and a water leakage detection cable. The electric control system is composed of a sensor, an actuator, and a PLC module. The cabin ventilation and heat dissipation outlet is installed with an electric controlled shutter facing outward, and a water leakage detection shutter is installed inward. Water pressure reducing dust-proof cotton is placed between the water leakage detection shutter and the electric control shutter to form a weatherproof shutter device. The water leakage detection module is connected to the water leakage detection cable in the water leakage detection shutter and the PLC module of the electric control system. The PLC module is connected to the temperature measuring instrument in the cabin and is connected to the electric controlled shutter through sensors and actuators.

[0006] Furthermore, the water leakage detection shutter includes a cable connection position, and the external connection terminals are all in the form of quick plugs; the water leakage detection cable is directly connected to the water leakage detection module.

[0007] Furthermore, the water leakage detection module detects the surface of the water leakage detection cable arranged inside the water leakage detection shutter, and when rainwater is detected on the surface of the cable, the water leakage detection module sends out an audible and visual alarm.

[0008] Furthermore, in the electrically controlled blinds, the motor and the blinds are connected to each other, and when the motor rotates, the blinds rotate accordingly.

[0009] Furthermore, the motor is powered by 24DCV and connected to the sensor and the actuator through the communication module. The sensor and the actuator are powered by 24DCV and connected to the PLC module through the communication module.

[0010] Furthermore, the PLC module uses 24DCV two-way power supply to connect the temperature measuring instrument and the local or remote integrated display and control screen through the communication module. In addition to being able to be viewed at any time, the integrated display and control screen can also be operated locally or remotely.

[0011] Furthermore, the PLC module cooperates with the sensor and the actuator to detect the temperature change signal fed back by the cabin temperature measuring instrument through the communication module, and starts the motor to rotate, thereby automatically adjusting the air volume of the shutter opening.

[0012] A control method for a marine weathertight shutter device, when a temperature measuring instrument measures a temperature change signal of a cabin, the signal is fed back to a PLC module through a communication module; the PLC module receives the temperature change signal fed back by the temperature measuring instrument through the communication module, cooperates with a sensor and an actuator, and controls the electric shutter to rotate through the communication module, automatically adjusting the air volume of the electric shutter opening until the temperature set in the cabin is reached; at the same time, the PLC module receives the sound and light alarm signal fed back by the leakage detection module when a leakage detection module detects rainwater on the surface of a leakage detection cable inside the shutter through the communication module; the PLC module cooperates with a sensor and an actuator through the communication module, and controls the electric shutter to rotate through the communication module, so as to discharge the rainwater to a drain outlet.

[0013] The beneficial effects of the present invention are:

[0014] The marine weathertight shutter device and control method of the present invention include water pressure reducing dustproof cotton, a water leakage detection system, an electric control system, and a temperature measuring instrument; the water leakage detection system includes a water leakage detection shutter (water leakage detection cable, shutter), a water leakage detection module, etc.; the electric control system includes an electric control shutter (motor, shutter), a sensor, an actuator, a PLC module, etc. In addition to the conventional rainproof and heat dissipation functions, the weathertight shutter device also includes dustproof, shutter opening air volume control, drain, water leakage detection alarm, temperature detection, detachable maintenance, etc., effectively increasing the cabin shutter opening air volume, preventing water ingress into the cabin, and preventing the risks caused by excessive temperature.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 The electrical connection diagram of the marine weathertight shutter device is shown. In the figure, the 24V power supply is supplied by AC220V and UPSDC24V (power will not be cut off in case of emergencies). The 24V power supply supplies power to the integrated display and control screen, the water leakage detection module, the PLC module, the sensor, the actuator, the 24V motor, and the temperature measuring instrument respectively. The integrated display and control screen, the water leakage detection module, the PLC module, the sensor, the actuator, the 24V motor, and the temperature measuring instrument use 485 communication to detect each other. The water leakage detection module and the water leakage detection cable are combined into a water leakage detection system, and the PLC module, the sensor, the actuator, and the 24V motor are combined into an electric control system. The water leakage detection system and the electric control system control the weathertight shutter device respectively. Combined into a marine weathertight shutter control method.

[0025] like Figure 2 The diagram shows the structure of the marine water pressure reducing dustproof cotton. Figure 2 The number of small holes in the water pressure reducing dustproof cotton in (a) and (b) is called fiber density, also called PPI value. It can effectively prevent dust, buffer water pressure, and does not affect air volume, and is also a flame retardant material. When used with blinds with water leakage detection and blinds with electric control, it can prevent dust and prevent rainwater from entering the cabin.

[0026] like Figure 3 The structure diagram of the marine water leakage detection shutter of the present invention is shown. Figure 3In (a) and (b), the water leakage detection cable 3 is arranged inside the shutter 2 to form a shutter with water leakage detection. The water leakage detection cable 3 arranged inside the leakage detection shutter 2 is directly detected by the water leakage detection module (powered by DC24V (two-way)). If there is rain on the surface of the water leakage detection cable 3, the water leakage detection module will send out an audible and visual alarm. The audible and visual alarm signal sent by the water leakage detection module is fed back to the local integrated display and control screen and the remote cabin operation panel through 485 communication. It can also be operated locally / remotely to form a shutter with water leakage detection that meets the requirements of marine use. The present invention designs a marine water leakage detection system. In addition to the water leakage detection module directly detecting rainwater on the surface of the water leakage detection cable 3 installed inside the shutter, the water leakage detection module sends out an audible and visual alarm. At the same time, the water leakage detection module sends out an audible and visual alarm signal through 485 communication and feeds it back to the PLC module. The PLC module receives the audible and visual alarm signal fed back by the water leakage detection module through 485 communication, cooperates with the sensor and the actuator through 485 communication to control the rotation of the electric shutter (the motor rotates, and the shutter rotates accordingly), and discharges the rainwater to the drain port 6, thereby forming a control method for the marine weathertight belt water leakage detection shutter.

[0027] like Figure 4 The figure shows the structure of the electric controlled shutter for ship. Figure 4 In (a) and (b), the motor 4 and the shutter 5 are combined into an electrically controlled shutter. The motor 4 and the shutter 5 are connected to each other. The PLC module controls the motor 4 to rotate through 485 communication, and the shutter 5 rotates accordingly. When the temperature measuring instrument measures the temperature change signal of the cabin and feeds it back to the PLC module through 485 communication, the PLC module receives the temperature change signal fed back by the temperature measuring instrument through 485 communication, cooperates with the sensor and the actuator to control the rotation of the electrically controlled shutter through 485 communication (the motor and the shutter are connected to each other), and automatically adjusts the air volume of the opening of the electric shutter until the cabin temperature is reached (used in conjunction with the cabin air conditioner and fan). It is combined into an electrically controlled shutter that meets the requirements of marine use. The present invention designs a marine electric control system. In addition to the temperature change signal of the cabin measured by the temperature measuring instrument being fed back to the PLC module through 485 communication, the PLC module receives the temperature change signal fed back by the temperature measuring instrument through 485 communication, cooperates with the sensor and the actuator through 485 communication to control the rotation of the electric control blinds (the motor and the blinds are connected to each other), and automatically adjusts the opening air volume of the electric blinds until the set temperature of the cabin is reached. At the same time, the PLC module receives the sound and light alarm signal fed back by the leakage detection module when the leakage detection module detects rainwater on the surface of the leakage detection cable 3 inside the blinds 2 through 485 communication; the PLC module cooperates with the sensor and the actuator through 485 communication to control the rotation of the electric blinds (the motor rotates, and the blinds rotate accordingly) through 485 communication, and discharges rainwater to the drain port 6, thereby forming a control method for marine wind and raintight electric control blinds.

[0028] like Figure 5 , 6 7 is a structural diagram and exploded diagram of the invented marine weathertight shutter device. Figure 5 and Figure 6 (a), (b) and Figure 7 The middle water pressure reducing dustproof cotton 1, the shutters with leakage detection 7 and the shutters with electric control 8 are combined into a wind and rain tight shutter device, the shutters with electric control 8 face outside the cabin, the water pressure reducing dustproof cotton 1 is placed in the middle, and the shutters with leakage detection 7 face the cabin, and the whole is installed at the ventilation and heat dissipation outlets of other places such as ship container box power supplies and ship battery cabins. When encountering severe weather such as storms, rainwater enters the electric blinds 7 and is buffered by the water-reducing dust-proof cotton 1. Assuming that part of the rainwater is not buffered by the water-reducing dust-proof cotton 1, the rainwater will hit the surface of the leakage detection cable 3 arranged inside the blinds 2. The leakage detection module directly detects the rainwater on the surface of the leakage detection cable 3 arranged inside the blinds 2, and the leakage detection module sends out an audible and visual alarm signal. At the same time, the audible and visual alarm signal sent by the leakage detection module through 485 communication is fed back to the PLC module. The PLC template receives the audible and visual alarm signal sent by the leakage detection module through 485 communication. The PLC template cooperates with the sensor and the actuator through 485 communication to control the rotation of the electric blinds (motor rotation, blinds rotation) through 485 communication to discharge the rainwater to the drain outlet 6. When the cabin temperature is too high or too low, the temperature change signal measured by the cabin temperature measuring instrument is fed back to the PLC module through 485 communication. The PLC module receives the temperature change signal fed back by the temperature measuring instrument through 485 communication. The PLC module cooperates with the sensor and actuator through 485 communication to control the rotation of the electric shutter (motor rotation, shutter rotation), and (at the same time cooperates with the cabin air conditioner or fan) automatically adjusts the wind volume of the windproof shutter opening until the cabin temperature is reached. The marine windproof shutter device is flexible to install and can be disassembled for maintenance, which effectively solves the problems that the windproof shutter cannot adjust the wind volume, cannot detect whether rainwater has entered the cabin, and the vents of some important places must be kept open.
