Description

Technical Field

[0001] The invention relates to the technical field of self-starting energy for ship emergency generators, and in particular to an automatic energy conversion device in an electrical combination form. Background Art

[0002] Emergency generators commonly found on ships, as one of the main forms of emergency power supply, are an important measure to obtain necessary electricity on board before the ship resumes normal power supply after the main power supply on board is lost. Emergency generators are even related to whether the ship can resume normal power supply, which shows that their importance to ship safety is self-evident. For such an important emergency generator, the relevant regulations and rules specifically require that the self-starting unit has two independent starting devices, including starting energy. The supporting energy forms are commonly: two sets of batteries (or compressed air), one set of batteries (or compressed air) and a mechanical starting device, among which the mechanical starting device includes springs, hydraulic energy storage, etc.

[0003] Practice shows that the emergency generator starting system that meets the requirements of the rules and regulations is normal in daily ship navigation through regular inspection and maintenance, but it has appeared more than once in real cases that for a specific ship sailing in a specific waters, a specific fault occurs, and the emergency generator cannot be started as soon as possible (including manual start-up does not work), or even the so-called "breakdown", and it is necessary to urgently check the possible starting problems item by item. At this point, every minute and every second that endangers the safety of the ship is very critical. In order to solve the urgent problem, we must race against time. Usually, although the self-starting system of the emergency generator meets the requirements of the rules and regulations, the control method of the switch box for the starting energy supply is only on-site manual operation. When it is necessary to switch the battery or switch to compressed air start-up, there will be a certain delay in time (manual intervention is required to start), which is also a very obvious "defect" for the safety of the ship at a critical juncture; in view of this, a multi-energy (electrical combination) automatic conversion device for the self-starting of the emergency generator on board is specially designed, which is naturally irreplaceable in terms of time to ensure the safety of the ship and restore it to normal as soon as possible at an extraordinary moment.

[0028] Among them, the first incoming line switch QS1 plays the role of overall on-off control of the automatic supply of specific starting energy (battery power); the first self-reset button SR1 can enable the second starting energy module to provide starting energy to the emergency generator. The first self-reset button SR1 is a normally closed button. When the first self-reset button SR1 is pressed, the first starting energy module will be in an off-circuit state, and the second starting energy module will be in a conducting state, thereby allowing the second energy to be online.

The surface of the conversion box is also provided with an indicator light corresponding to the first energy online, that is, the preferred starting energy (battery pack or gas cylinder) can be rotated by pressing the self-reset button (SR1 or SR2) during the working cycle;

[0032] In addition, the function of the fuse is to provide short-circuit protection for the two control circuits of the first starting energy module and the second starting energy module; the gas pressure switch 2PS installed on the starting gas cylinder is connected to the corresponding control output circuit in the conversion box to monitor the gas cylinder pressure and make automatic conversion conditions. That is to say, when the second starting energy module is used to provide starting power to the emergency generator, when the pressure in the gas cylinder is lower than the rated safety pressure, the gas pressure switch will be disconnected, so that the first starting energy module can provide starting energy to the emergency generator.

[0033] See also Figure 1The second starting energy module also includes a test light submodule, a first indicator light submodule and a second indicator light submodule.

[0034] See also Figure 2 and Figure 3 The test light submodule includes a third contactor coil, a third self-reset button, a fifth fuse and a sixth fuse. The third contactor KM3 coil, the third self-reset button SR3, the fifth fuse 3FU1 and the sixth fuse 3FU2 are selected as examples for explanation below; one end of the third contactor KM3 coil is connected to the local control box, the second switch control submodule and the second switch submodule respectively through the sixth fuse 3FU2, the other end of the third contactor KM3 coil is connected in series with the third self-reset button SR3, and the other end of the third self-reset button SR3 is connected to the local control box, the second switch control submodule and the second switch submodule respectively through the fifth fuse 3FU1, wherein the function of the test light submodule is to test whether the first energy online indicator light PWR1 and the second energy online indicator light PWR2 mentioned below are faulty, and the third self-reset button SR3 is a normally open button. In addition, an indicator light corresponding to the test light submodule is also provided on the surface of the conversion box.

[0035] See also Figure 2 The first indicator light module includes a first energy online indicator light, a second normally open contact of a first contactor, a first normally open contact of a third contactor, a seventh fuse and an eighth fuse. The first energy online indicator light PWR1, a second normally open contact of a first contactor KM1, a first normally open contact of a third contactor KM3, a seventh fuse 4FU1 and an eighth fuse 4FU2 are selected as examples for explanation;

[0036] One end of the first energy online indicator light PWR1 is connected to the local control box, the second indicator light submodule, the second switch control submodule, the test light submodule and the second switch submodule respectively through the eighth fuse 4FU2; the other end of the first energy online indicator light PWR1 is connected in series with the second normally open contact of the first contactor KM1, and the second normally open contact of the first contactor KM1 is also connected to the local control box, the second indicator light submodule, the second switch control submodule, the test light submodule and the second switch submodule respectively through the seventh fuse 4FU1, and the first normally open contact of the third contactor KM3 is connected in parallel with the second normally open contact of the first contactor KM1, wherein, when the first starting energy module is used to provide starting energy to the emergency generator, the coil of the first contactor KM1 is energized, the second normally open contact of the first contactor KM1 will be closed, and the first energy online indicator light PWR1 will light up.

[0037] See also Figure 2The second indicator light module includes a second energy online indicator light, a second normally open contact of a second contactor, a second normally open contact of a third contactor, a ninth fuse and a tenth fuse. The second energy online indicator light PWR2, a second normally open contact of a second contactor KM2, a second normally open contact of a third contactor KM3, a ninth fuse 4FU3 and a tenth fuse 4FU4 are selected as examples for explanation;

[0038] One end of the second energy online indicator light PWR2 is connected to the local control box, the first indicator light submodule, the second switch control submodule, the test light submodule and the second switch submodule respectively through the tenth fuse 4FU4; the other end of the second energy online indicator light PWR2 is connected in series with the second normally open contact of the second contactor KM2, and the second normally open contact of the second contactor KM2 is also connected to the local control box, the first indicator light submodule, the second switch control submodule, the test light submodule and the second switch submodule respectively through the ninth fuse 4FU3, and the second normally open contact of the third contactor KM3 is connected to the second normally open contact of the second contactor KM2 The contacts are connected in parallel; when the second starting energy module is used to provide starting energy to the emergency generator, the second contactor KM2 coil is energized, the second normally open contact of the second contactor KM2 will be closed, and the second energy online indicator light PWR2 will light up; when a light test is required, the third self-reset button SR3 is pressed to close the third self-reset button SR3, the third contactor KM3 coil is energized, the first normally open contact of the third contactor KM3 and the second normally open contact of the third contactor KM3 will be closed, and if the first energy online indicator light PWR1 and the second energy online indicator light PWR2 are fault-free, they will light up at the same time.

[0039] Also in Figure 2 In the present invention, the third normally open contact of the first contactor KM1 and the third normally open contact of the second contactor KM2 are also connected to the local control box. The first contactor KM1 and the second contactor KM1 each have a normally open contact connected to the local control box of the emergency generator to facilitate the staff at the local control box to know whether the battery is online or the gas cylinder is online at this time, that is, the conversion box is also provided with an online status output of the starting energy (battery power and compressed air power) (to the local control box of the emergency generator).

[0040] Specifically, the present invention is applicable to the automatic conversion between a group of batteries (storage batteries) and a group of gas cylinders (compressed air) as the starting energy source; and all electrical components in the conversion box of the present invention refer to Figure 2Electrical connections are made to form a "two-in, two-out" topological structure; the conversion box is connected to the starting battery pack and the local control box of the emergency generator respectively, directly introducing the starting energy and control power supply DC24V, and the output is connected to the electric starting motor on the emergency generator set and the solenoid valve on the gas supply pipeline corresponding to the starting gas cylinder; during the ship's operating life cycle, the conversion box can be transformed and upgraded as needed, and other starting energy sources, such as the conversion function of "dual electricity" or "dual gas" combination, can be realized by re-combining the connection of the components in the conversion box.

[0041] More specifically, when the electrical combination energy automatic conversion device is used, the first starting energy module is selected as the preferred energy source, and the second starting energy module is selected as the alternative energy source. First, on the premise of ensuring that the internal and external wiring of the conversion box is correct, the first incoming line switch QS1 and the second incoming line switch QS2 are manually closed in sequence (at intervals of 2 to 3 seconds), and the cylinder pressure switch 2PS is also closed. When the first incoming line switch QS1 is closed, the coil of the first contactor KM1 is energized, and the normally open contact of the first contactor KM1 is closed, so that the first starting energy module is in a conducting state, so that the battery pack can be connected to the electric starter motor to achieve the purpose of starting the emergency generator; at the same time, the first contactor KM1 is normally closed. The closed contact is disconnected, so that the second starting energy module is in an open circuit state; if there is a problem with the first starting energy module, the coil of the first contactor KM1 will not be energized, and the normally closed contact of the first contactor KM1 will be closed, so that the second starting energy module is in a conducting state, so that the local control box can be connected to the solenoid valve of the starting gas cylinder, so that the automatic conversion of the self-starting energy supply (battery power and compressed air power) of the emergency generator on board can be realized; if the second starting energy module is selected as the preferred energy source, the first starting energy module is the alternative energy source, first close the second incoming line switch QS2, and then close the first incoming line switch QS1, the subsequent operation steps are similar to the above content, and no further description is given here;

[0042] In addition, it should be noted that when troubleshooting, all incoming line switches can be disconnected and the corresponding components or circuits can be troubleshooted and replaced by referring to the electrical principle wiring diagram.

[0043] In summary, in the present invention, the first starting energy module contains the first contactor KM1 coil and the second contactor KM2 normally closed contact, and the second starting energy module contains the second contactor KM2 coil and the first contactor KM1 normally closed contact, so that the first starting energy module responds to the control signal sent when the second starting energy module is disconnected to be in a conductive operating state, and the second starting energy module also responds to the control signal sent when the first starting energy module is disconnected to be in a conductive operating state, so that the first starting energy module and the second starting energy module can be switched, so that the automatic switching of the self-starting energy (battery power and compressed air power) supply of the emergency generator on board can be realized, wherein the first starting energy module is a battery power energy source, and the second starting energy module is a compressed air power energy source, one of the first starting energy module and the second starting energy module is used as the preferred starting energy source, and the other is used as an alternative starting energy source, when the preferred starting energy connected to the emergency generator cannot start the emergency generator, it can be automatically switched to the alternative starting energy source and connected to the emergency generator, realizing a zero-time delay conversion, ensuring the normal startup of the emergency generator, and ensuring the safety of the ship to the greatest extent;

[0044] The first starting energy module also contains a first self-reset button SR1, and the second starting energy module also contains a second self-reset button SR2. The staff presses the normally closed first self-reset button SR1 to make the compressed air power energy in the second starting energy module the preferred starting energy, or the staff presses the normally closed second self-reset button SR2 to make the battery power energy in the first starting energy module the preferred starting energy, thereby manually and periodically setting the preferred starting energy. This manual and periodic setting of the preferred starting energy can relatively extend the service life of the starting energy.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
