Description

Technical Field

[0001] This invention relates to the field of marine safety technology, and more specifically to a striker for transmitting damage control signals. Background Technology

[0002] Damage control, or damage management, refers to the measures and actions taken by a warship to prevent, limit, and eliminate damage in order to maintain or restore its survivability. Damage control signals are warning signals issued before damage control is implemented. In modern warships, fire-fighting equipment has evolved into automatic alarm and fire-fighting systems. However, due to excessive noise in engine rooms such as main engines and auxiliary engines, damage control signals are still transmitted by manually striking the bulkheads. Damage control signals, as the deployment signal for damage control, are even more crucial. Only with timely and accurate transmission of damage control signals can correct actions be taken immediately, minimizing losses, maintaining survivability, reducing equipment damage, and protecting personnel safety. The main contents of damage control include preventing sinking and plugging leaks, extinguishing fires, evacuating personnel, and repairing equipment. One consecutive short blast indicates a fire, two consecutive short blasts indicate flooding, and three consecutive short blasts indicate abandonment. Shipboard personnel are required to memorize and master these signals. However, in the event of an emergency, personnel may be too nervous to find the mallet in time or strike the wrong damage control signal. Summary of the Invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a striking device for transmitting damage control signals. By setting a first striking device, a second striking device and a third striking device, different damage control signals can be generated quickly according to the emergency situation. Compared with the old-fashioned striking methods and equipment, it has the advantages of being more scientific, simpler, faster, easier and more efficient.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A striking device for transmitting damage control signals includes a main body and a damage control signal circuit. Three sets of control buttons are mounted on the front of the main body. Inside the main body, near the bottom of the three sets of control buttons, are respectively arranged a first striking device, a second striking device, and a third striking device. The output terminals of the first, second, and third striking devices are each connected to a striking mechanism. The striking mechanism is used to strike the interior wall of the compartment to generate a damage control signal. The first striking device is used to generate one sound damage control signal, the second striking device is used to generate two sound damage control signals, and the third striking device is used to generate three sound damage control signals. The damage control signal circuit includes three parallel striking circuits, which are used to generate one, two, and three sound signals, respectively.

[0006] As a further aspect of the present invention: the main body of the device is made of a 3 mm 304 aluminum alloy outer layer bonded with foamed aluminum fireproof material. Foamed aluminum is formed by mixing a foaming agent into aluminum and aluminum alloy, and expanding it in a liquid, solid or liquid-solid coexistence state. It is lightweight, low density, large specific surface area, and suitable structural strength. It has the characteristics of fireproof, moisture-proof, non-toxic and odorless. The shell made of this material is both strong and fireproof and water-resistant.

[0007] As a further aspect of the present invention: the control button includes a connecting terminal, a support spring and a button block, and the surfaces of the three button blocks are coated with red, blue and black respectively, corresponding to the first striker, the second striker and the third striker. The blue and black control buttons correspond to the first water, the second fire and the third abandoned compartment respectively.

[0008] As a further aspect of the present invention: a smoke sensor, a temperature sensor, and a water pressure sensor are externally connected to the main body of the device.

[0009] As a further aspect of the present invention: the first percussion device includes a first mounting body, a first brushless motor is mounted on the top surface of the first mounting body, and a first cam is connected to the output end of the first brushless motor. When the control button corresponding to the first percussion device is pressed, the circuit of the first brushless motor will be closed, the first brushless motor will start and drive the first cam to rotate. The curved motion of the first cam drives the percussion mechanism to achieve continuous single-beat percussion and emit a short sound loss signal.

[0010] As a further aspect of the present invention: the second percussion device includes a second mounting body, on the top surface of the second mounting body is a second brushless motor, and the output end of the second brushless motor is connected to a second cam. When the control button corresponding to the second percussion device is pressed, the circuit of the second brushless motor will be closed, the second brushless motor will start and drive the second cam to rotate. The curved motion of the second cam drives the percussion mechanism to achieve continuous single-beat percussion and emit two short sound loss tube signals.

[0011] As a further aspect of the present invention: the third percussion device includes a third mounting body, on the top surface of the third mounting body is a third brushless motor, and the output end of the third brushless motor is connected to a third cam. When the control button corresponding to the third percussion device is pressed, the circuit of the third brushless motor will be closed, the third brushless motor will start and drive the third cam to rotate. The curved motion of the third cam drives the percussion mechanism to achieve continuous single-beat percussion and emit three short sound loss tube signals.

[0012] As a further aspect of the present invention: the striking mechanism includes a connecting rod, one end of which is in contact with a first striking device, a second striking device, or a third striking device, and the other end of which is fixedly connected to a weight. When the first striking device, the second striking device, or the third striking device is activated, it will push the connecting rod, which will then push the weight, causing the weight to strike the inner wall of the cabin.

[0013] The beneficial effects of this invention are:

[0014] The main body of the device is made of 304 aluminum alloy with a layer of foamed aluminum fireproof material bonded to it. Foamed aluminum is made by mixing foaming agent into aluminum and aluminum alloy and expanding it in a liquid, solid or liquid-solid coexistence state. It is lightweight, low density, large specific surface area, and suitable structural strength. It has the characteristics of fireproof, moisture-proof, non-toxic and odorless. The shell made of this material is both strong and fireproof and water resistant.

[0015] By using the first, second, and third striking devices, different damage control signals can be generated quickly according to the emergency situation. Compared with the old-fashioned striking methods and equipment, it has the advantages of being more scientific, simpler, faster, easier, and more efficient. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1:

[0027] like Figures 1-6 As shown, a knocker for transmitting damage control signals includes a device body 1. Three sets of control buttons 2 are mounted on the front of the device body 1. Inside the device body 1, near the bottom surface of the three sets of control buttons 2, a first knocker 3, a second knocker 4, and a third knocker 5 are respectively arranged. The output ends of the first knocker 3, the second knocker 4, and the third knocker 5 are respectively connected to a knocking mechanism 6. The knocking mechanism 6 is used to knock on the inner wall of the compartment to generate damage control signals. The first knocker 3 is used to make the knocking mechanism 6 generate one damage control signal, the second knocker 4 is used to make the knocking mechanism 6 generate two damage control signals, and the third knocker 5 is used to make the knocking mechanism 6 generate three damage control signals.

[0028] The main body of the device 1 is made of 3 mm 304 aluminum alloy with foamed aluminum fireproof material bonded to the outer layer. Foamed aluminum is made by mixing foaming agent into aluminum and aluminum alloy and expanding it in liquid, solid or liquid-solid coexistence state. It is lightweight, low density, large specific surface area, and suitable structural strength. It has the characteristics of fireproof, moisture-proof, non-toxic and odorless. The shell made of this material is both strong and fireproof and water resistant.

[0029] By using the first striker 3, the second striker 4, and the third striker 5, different damage control signals can be generated quickly according to the emergency situation. Compared with the old-fashioned striking methods and equipment, it has the advantages of being more scientific, simpler, faster, easier, and more efficient.

[0030] like Figure 2As shown, the control button 2 includes a mounting block 21. One side of the mounting block 21 is provided with a connection terminal 22, a support spring 23 and a button block 24. The surfaces of the three button blocks 24 are coated with red, blue and black respectively, corresponding to the first striker 3, the second striker 4 and the third striker 5. The red, blue and black control buttons 2 correspond to the first water, the second fire and the third abandoned compartment respectively.

[0031] The main body 1 of the device is externally connected to a smoke sensor, a temperature sensor, and a water pressure sensor.

[0032] like Figure 3 As shown, the first percussion device 3 includes a first mounting body 31. A first brushless motor 33 is mounted on the top surface of the first mounting body 31. The output end of the first brushless motor 33 is connected to a first cam 34. One end of the first mounting body 31 is connected to a first connecting cable 32. When the control button 2 corresponding to the first percussion device 3 is pressed, the circuit of the first brushless motor 33 will be closed, the first brushless motor 33 will start, and drive the first cam 34 to rotate. The curved motion of the first cam 34 drives the percussion mechanism 6, so that the percussion mechanism 6 can continuously strike once and emit a short sound loss tube signal.

[0033] like Figure 4 As shown, the second percussion device 4 includes a second mounting body 41. A second brushless motor 43 is mounted on the top surface of the second mounting body 41. The output end of the second brushless motor 43 is connected to a second cam 44. One end of the second mounting body 41 is connected to a second connecting cable 42. When the control button 2 corresponding to the second percussion device 4 is pressed, the circuit of the second brushless motor 43 will be closed, the second brushless motor 43 will start, and drive the second cam 44 to rotate. The curved motion of the second cam 44 drives the percussion mechanism 6, so that the percussion mechanism 6 can continuously strike once and emit two short sound loss tube signals.

[0034] like Figure 5 As shown, the third percussion device 5 includes a third mounting body 51. A third brushless motor 53 is mounted on the top surface of the third mounting body 51. The output end of the third brushless motor 53 is connected to a third cam 54. One end of the third mounting body 51 is connected to a third connecting cable 52. When the control button 2 corresponding to the third percussion device 5 is pressed, the circuit of the third brushless motor 53 will be closed, the third brushless motor 53 will start, and drive the third cam 54 to rotate. The curved motion of the third cam 54 drives the percussion mechanism 6, so that the percussion mechanism 6 can continuously strike once and emit three short sound loss tube signals.

[0035] like Figure 6As shown, the striking mechanism 6 includes a connecting rod 61. One end of the connecting rod 61 is in contact with the first striking device 3, the second striking device 4, or the third striking device 5, respectively. The other end of the connecting rod 61 is fixedly connected to a hammer 65. A return spring 62 is nested on the side of the connecting rod 61. One end of the return spring 62 is fixedly connected to a mounting plate 63, and the other end of the return spring 62 is fixedly connected to a fixing plate 64. The mounting plate 63 is fixedly installed inside the main body 1 of the device, and the fixing plate 64 is fixedly nested on the side of the connecting rod 61.

[0036] When the first percussion device 3, the second percussion device 4, or the third percussion device 5 is activated, it will push the connecting rod 61, which in turn will push the hammer 65, causing the hammer 65 to strike the inner wall of the cabin.

[0037] Example 2:

[0038] For damage control signal circuits, such as Figure 7 As shown, the damage control signal circuit includes three parallel striking circuits, which are used to generate one-shot, two-shot, and three-shot signals, respectively. Resistors R1 to R6 form an electric bell. In the first circuit, resistor R1 and electrode tube one are connected in series, and electrode tube one controls the connection of the resistor R1 circuit. In the second circuit, resistors R2 and R3 are connected in series with electrode tube two, and electrode tube two controls the connection of the resistors R2 and R3 circuit. In the third circuit, resistors R4, R5, and R6 are connected in series with electrode tube three, and electrode tube three controls the connection of the resistors R4, R5, and R6 circuit. One side of this circuit is also connected via an inductor. An external power supply is provided to ensure that the signal circuit remains powered even when the power supply is damaged. When a single beep is required, electrode one is turned on, connecting resistor R1 to generate a single beep. When a second beep is required, electrode two is turned on, connecting resistors R2 and R3 to generate a double beep. When a third beep is required, electrode three is turned on, connecting resistors R4, R5, and R6 to generate a triple beep.

[0039] Working principle of the invention:

[0040] When water enters the cabin, pressing the red control button 2 will close the circuit of the first brushless motor 33, start the first brushless motor 33, and drive the first cam 34 to rotate. The first cam 34's curved motion drives the striking mechanism 6, enabling the striking mechanism 6 to strike continuously and emit a short sound loss signal.

[0041] When a fire occurs in the cabin, pressing the blue control button 2 will close the circuit of the second brushless motor 43, start the second brushless motor 43, and drive the second cam 44 to rotate. The curved motion of the second cam 44 drives the striking mechanism 6 to continuously strike once, emitting two short sound loss tube signals.

[0042] When water enters the cabin, pressing the black control button 2 will close the circuit of the third brushless motor 53, start the third brushless motor 53, and drive the third cam 54 to rotate. The curved motion of the third cam 54 drives the striking mechanism 6, so that the striking mechanism 6 strikes continuously and emits three short sound loss tube signals.

[0043] This ensures that the striking mechanism 6 can send signals more quickly and accurately when an accident occurs.

[0044] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
