Fans can be found in various places, such as blast blowers of smelters, pipeline fans on construction sites, exhaust fans of operation workshops and the like. On the ship, the fan is an indispensable object, and for example, the engine room must be equipped with the fan, which is responsible for supplying oxygen to the main engine in addition to discharging heat and exhaust gas emitted by the main engine.

In the existing ship, the power supply of the fan is generally independent, and the fan needs to be manually started before being started every time. There are also some ships, and the power supply of the fan is associated with the main power supply, and when the ship is powered on for the total power, the fan power supply is powered on. However, the unmanned ship or the small-sized ship has little space in the cabin due to the narrow space of the cabin, and after the main engine (engine) is placed in the cabin, the small space means that the temperature of the cabin can rapidly rise along with the operation of the main engine, and the oxygen in the air can be greatly consumed. Therefore, the demand for wind turbines for unmanned boats or small ships is more urgent.

If the power supply of the unmanned ship fan needs to be manually turned on every time, the driver is required to have extremely strong responsibility, and whether the unmanned ship fan is turned on or not needs to be checked every time before the host is turned on. If the unmanned ship needs to be placed on a wharf for debugging or relevant communication tasks, the unmanned ship is required to start the main power supply, but the main machine of the unmanned ship does not need to be started (namely, the ignition switch is in a flameout state), and when the power supply of the fan is related to the main power supply of the unmanned ship, the fan is also started along with the starting of the main power supply in the state. The control mode of these two kinds of fan power all has the defect, and mode one needs the independent switch, forgets easily, and mode two causes the loss of electric energy easily, and long-time static is used, needs the manual work to charge many times. In view of these problems, a power supply scheme is needed to turn on the fan only when the fan is needed.

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more, and "several" means one or more unless specifically limited otherwise.

The fan starting device provided by the embodiment of the application comprises a first control switch and an ignition switch. Referring to fig. 1, the ignition switch has an OFF line (i.e., "OFF"), an ON line (i.e., "ON"), and a START line (i.e., "START"), when the key is in the "OFF" position, the host (e.g., an internal combustion engine) is in a non-START flameout state, when the key is turned to "ON", the host is powered ON, at this time, the host dashboard indicator light is turned ON and displays some key information such as oil pressure, water temperature, and the like, and when the key is turned to the "START" position and is maintained for 3-5S, the host is started. The device for setting the host is, for example, a boat, an automobile, an electric vehicle, etc., and the embodiments of the present application will be described with reference to a boat as an example.

Referring to fig. 2, in the first embodiment, the first control switch 2 has a first electrode L1, a second electrode L2, a first contact M and a second contact N, the fan 5 and the power source 4 are connected in series between the first contact M and the second contact N, and the second electrode L2 is connected to the negative pole of the power source 4; the upper wire B of the ignition switch 1 is connected to the first electrode L1, and the ignition switch 1 is configured to provide a voltage signal to the first electrode L1 when the upper wire B is powered on, so that the first contact M and the second contact N are conducted to power on the fan 5. Because the ignition switch 1 is used for controlling the host and the fan 5 is associated with the host, when the key is turned to 'ON' manually, the host is powered ON and the fan 5 is powered ON, so that a user does not need to control the fan 5 to be started and stopped independently, damage caused by starting cannot be forgotten, and resource waste caused by starting cannot be forgotten to be stopped or not required.

Alternatively, the first control switch 2 is a contactor or a relay, the first electrode L1 and the second electrode L2 are two ends of the coil of the first control switch 2, respectively, and the first contact M and the second contact N are two contacts of the normally open switch of the first control switch 2. Optionally, the blower starting device further includes a fuse 3, and the fuse 3 is connected between the first contact M and the positive electrode of the power supply 4, and is mainly used for protecting the power supply 4.

Optionally, the power source 4 is a dc power source, and may be a battery or a distribution box. The fan 5 is a direct current fan, and the direct current fan is selected because the volume is smaller than that of an alternating current fan, so that the space is saved, and the fan is suitable for small ships and unmanned boats.

When the key of the ignition switch 1 is turned to the "ON" position, the first electrode L1 introduces a voltage signal, and after the first electrode L1 and the second electrode L2 are powered, the first contact M and the second contact N ON the first control switch 2 are conducted, at this time, the fan 5 is switched ON to the power supply 4, and the fan 5 is powered ON and started. Therefore, during manual operation, as long as the host is started, the corresponding fan 5 is started after being powered on, and the risk that the host is possibly damaged due to overhigh cabin temperature and insufficient oxygen supply caused by the fact that the fan 5 is forgotten to be started manually is reduced. In addition, when the boat is parked and debugged in a harbor basin or a wharf, only certain equipment is needed to be started without starting a host, and at the moment, the fan is powered on without misoperation, so that the invalid loss of energy is avoided. For the fans requiring the secondary switch control power supply, the invention can greatly reduce the workload.

Referring to fig. 3, in the second embodiment, the blower starting device includes a first control switch 50, an ignition switch (not shown), a second control switch 20 and a wireless receiving module 30, wherein the connection manner of the first control switch 50, the ignition switch, the fuse 60, the power supply 70 and the blower 80 in the present embodiment is the same as that in the first embodiment, and is not described again here.

The second control switch 20 may be a relay or a contactor.

In this embodiment, the blower starting apparatus is connected to the host instrument panel 10 by connecting a line in parallel to a power line P1 and an upper line P2 of the host instrument panel 10, respectively, and connecting the power line P1 to a common terminal COM of a normally open switch of the second control switch 20, and connecting the upper line P2 to a normally open terminal NO of the normally open switch. It is understood that the power supply line P1 also serves as a power supply line for supplying power to the ignition switch 1. The driving coil of the second control switch 20 is controlled by the wireless receiving module 30 through the general purpose input/output port. The wireless receiving module 30 performs data interaction with a wireless transmitting module arranged in the shore-based control center 40 in a wireless communication mode, and the wireless transmitting module is used for transmitting a wireless power-on signal.

When the boat host needs to be remotely started, the shore-based control center 40 performs information interaction with the wireless receiving module 30 through wireless communication, the shore-based control center 40 sends a corresponding instruction, the wireless receiving module 30 controls the second control switch 20 to be closed, at the moment, the upper power line P2 of the host introduces a voltage signal of the power line P1, the corresponding first control switch 50 also introduces the voltage signal, the first contact M and the second contact N are conducted, the fan 80 starts to be powered on and started, and when the fan 80 is not needed to be started, the power failure of the fan 80 can be realized by remotely turning off the host.
