Description

Technical Field

[0001] The utility model relates to the technical field of ship lifesaving, in particular to a signal lamp with a lifebuoy combined signal. Background Art

[0002] The signal light of the lifebuoy combination signal usually refers to the signal light installed on the lifebuoy or used in conjunction with it. This type of signal light is mainly used to emit light signals in emergency situations to indicate the position of the lifebuoy at night or in low visibility environments, thereby improving rescue efficiency. The lifebuoy signal light can automatically light up after the lifebuoy is thrown into the water without manual operation. The self-igniting light usually uses seawater batteries or dry batteries as power supply, with a long service life and stable luminous performance. With the development of the times, some lifebuoys are equipped with a combination smoke signal in addition to the self-igniting light. This signal can indicate the position by emitting orange smoke during the day, complementing the self-igniting light to improve the rescue effect under all-weather conditions.

[0003] For example, a Chinese patent (publication number: CN209839901U) discloses a lifebuoy self-igniting floating light, which includes a bulb, an upper shell, and a lower shell. The upper shell is provided with a first cavity, the top of the first cavity is provided with a fixing seat, and the bulb is mounted on the fixing seat; the top of the upper shell is threadedly connected to the lampshade; the lower shell is provided with a second cavity, and the second cavity is provided with a control circuit board, a battery, a counterweight and a water contact terminal in sequence; the top of the second cavity is screwed to a fixing plate, and the fixing plate is provided with a mercury switch; the upper shell and the lower shell are matched and sealed. The self-igniting floating light of the lifebuoy provided by this utility model has a compact structure, automatically turns on and floats on the water surface after falling into the water, and the lampshade with sun-ray processing makes the LED lamp emit light more evenly, making it easier to obtain rescue.

[0004] However, the device is not stable enough. When the mercury switch is in a horizontal state, the circuit is disconnected. When the mercury switch is in the range of 45° to 135°, the circuit is connected. The waves on the sea are constant, and it is impossible to guarantee that it is in a connected state at all times. The flickering light will delay rescue. Therefore, a signal light with a lifebuoy combination signal is proposed to solve the above problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a signal light with a lifebuoy combination signal, which has the advantages of stable use and solves the problem of complex sea conditions and unstable use.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a signal light for a lifebuoy combination signal, comprising a smoke combination signal, wherein a signal light indicating the specific location of a person falling into the water is provided on the top of the smoke combination signal, wherein the signal lights are two and are respectively located on the left and right sides of the smoke combination signal;

[0007] Each of the signal lights includes a shell threadedly connected to the smoke combination signal, a lampshade is fixed to the top wall of the shell, a base is clamped at the bottom of the shell, a trapezoidal soft rubber is fixed on the top of the base, and an electric control component is arranged inside the shell.

[0008] Furthermore, the electronic control component includes a light-emitting portion and a switch portion abutting against the inner wall of the housing, a positioning portion is provided between the switch portion and the light-emitting portion, and a battery is abutted between the light-emitting portion and the switch portion.

[0009] Furthermore, the light-emitting portion includes a light-emitting circuit board that abuts against the inner wall of the shell, and an electric lamp is fixedly connected to the light-emitting circuit board.

[0010] Furthermore, the switch portion includes a switch circuit board that abuts against the top of the trapezoidal soft rubber, and a pressure switch is provided on the switch circuit board.

[0011] Furthermore, the positioning portion includes a positioning circuit board located between the light-emitting circuit board and the switch circuit board and connected to both of them, and an inversion sensor is provided on the positioning circuit board.

[0012] Furthermore, a sealing ring is fixed on the inner side of the base, and the other side of the sealing ring is in contact with the outer wall of the shell.

[0013] Furthermore, the base is trapezoidal, and the base is adapted to the trapezoidal soft rubber.

[0014] Furthermore, the trapezoidal soft rubber extends to the outside of the base, a protrusion is fixed to the bottom of the trapezoidal soft rubber, the protrusion is located on the outside of the base, and the inner side of the trapezoidal soft rubber is adapted to the pressure switch.

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] The signal light of the lifebuoy combination signal, generally, the smoke combination signal is inverted on the boat, at this time due to the effect of the positioning part, even if the switch part and the smoke combination signal are offset, the light-emitting part will not be triggered. When the lifebuoy falls into the water, the smoke combination signal will enter the water with the signal light. Since one end of the smoke combination signal is heavy and the other end is light, the light end will be exposed on the water surface, and at this time the signal light will be exposed on the water surface. Since the signal light is facing upward at this time, the positioning part and the switch part cooperate to prompt the light-emitting part to emit light stably, and the signal light can help rescue personnel successfully find the person who fell into the water.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 In this embodiment, a signal light for a lifebuoy combination signal includes a smoke combination signal 1. A signal light 2 for displaying the specific location of a person falling into the water is provided on the top of the smoke combination signal 1. There are two signal lights 2, which are respectively located on the left and right sides of the smoke combination signal 1.

[0023] In this embodiment, when someone falls into the water, the signal light 2 will fall along with the smoke combination signal 1. After the signal light 2 falls into the water, the smoke combination signal 1 will flip under the action of buoyancy, causing the signal light 2 to face upward. At this time, the signal light 2 can emit light stably.

[0024] See also Figures 1 to 2 In order to improve the stability of the signal light, each signal light 2 in this embodiment includes a shell 201 that is threadedly connected to the smoke combination signal 1. A lampshade 202 is fixed to the top wall of the shell 201. A base 203 is clamped on the bottom of the shell 201. A trapezoidal soft rubber 204 is fixed on the top of the base 203. The trapezoidal soft rubber 204 can transmit pressure and also has a waterproof effect. An electric control component 205 is provided in the shell 201.

[0025] In addition, a sealing ring is fixed on the inner side of the base 203, and the other side of the sealing ring is in contact with the outer wall of the shell 201. The sealing ring can prevent seawater from entering the shell 201, thereby increasing the service life of the signal light 2. The base 203 is trapezoidal, and the base 203 is adapted to the trapezoidal soft rubber 204.

[0026] It can be known that the trapezoidal soft glue 204 extends to the outside of the base 203, and a protrusion is fixed to the bottom of the trapezoidal soft glue 204. The protrusion can transfer pressure to the switch part 2052 through the trapezoidal soft glue 204, helping the signal light 2 to light up smoothly. The protrusion is located on the outside of the base 203, and the inside of the trapezoidal soft glue 204 is adapted to the pressure switch.

[0027] In addition, the electronic control component 205 includes a light-emitting portion 2051 and a switch portion 2052 that are abutted against the inner wall of the outer shell 201. A positioning portion 2053 is provided between the switch portion 2052 and the light-emitting portion 2051. A battery 2054 is abutted between the light-emitting portion 2051 and the switch portion 2052. The battery 2054 can provide good power for the signal light 2, and through the joint action of the light-emitting portion 2051 and the switch portion 2052, the battery 2054 can be effectively limited to ensure that the battery 2054 is stably stored in the outer shell 201.

[0028] The light-emitting portion 2051 includes a light-emitting circuit board that is against the inner wall of the outer shell 201, and an electric light is fixedly connected to the light-emitting circuit board. The switch portion 2052 includes a switch circuit board that is against the top of the trapezoidal soft rubber 204, and a pressure switch is provided on the switch circuit board. The pressure switch is a long-press switch that requires continuous pressure to be effective. The positioning portion 2053 includes a positioning circuit board located between the light-emitting circuit board and the switch circuit board and clamped with the two, and an inversion sensor is provided on the positioning circuit board.

[0029] In this embodiment, the trapezoidal soft glue 204 provides a sealing effect, and the electronic control component 205 realizes circuit control, which cooperates with the switch part 2052 to further improve the stability of the signal light 2 and ensure that the device can operate stably.

[0030] It is understandable that when the smoke combination signal 1 falls into the water, the signal light 2 will flip along with the smoke combination signal 1. Under the joint action of the positioning part 2053 and the switch part 2052, the light-emitting part 2051 will emit light smoothly and stably, thereby helping rescuers find the person who falls into the water faster.

[0031] See also Figure 3 In order to achieve the electronic control effect, the signal light 2 in this embodiment is powered by a battery 2054. K1 is a touch button and is in the off state before loading. After loading and installation, an external force is applied through the external result. When the K1 button is in the normally closed state, the power is turned on. SW is an inverted switch with the characteristic of being connected when forward and disconnected when inverted. The specific operating principle is as follows:

[0032] 1. The combined signal light 2 is usually installed upside down on the side of the bridge. When someone falls into the water, the lifebuoy is released to drive the signal light 2 into the water.

[0033] 2. Under the action of buoyancy, signal light 2 faces upwards and floats on the water. After the SW is turned on for more than two seconds, pin 3 of the U2 control chip will output a control signal, turning on the Q1 transistor and the LED will flash.

[0034] 3. When the signal is inverted, if SW is disconnected for more than 2 seconds, the U2 control circuit will automatically turn off the LED flashing.

[0035] 4. K1 is in the disconnected state before installation. At this time, the U2 control circuit is not connected, so the LED will not flash and the power is in the disconnected state.

[0036] 5.U1, L1, D1, D3, R1, C1, C2, and LED form a boost constant current drive LED lighting circuit, and U2, K1, S-type switch, D2, C3, R3, R4, and Q1 form a flashing control circuit.

[0037] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. Moreover, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0038] The working principle of the above embodiment is:

[0039] During transportation, the signal light 2 is first inserted into the smoke combination signal 1, but not completely tightened, so as to ensure that the switch part 2052 does not contact the smoke combination signal 1. When equipped on the ship, the signal light 2 is first tightened to the smoke combination signal 1, and the smoke combination signal 1 is turned upside down. In this way, under the action of the positioning part 2053, it can be ensured that the light-emitting part 2051 does not emit light. When someone falls into the water, the smoke combination signal 1 will fall with the lifebuoy. At this time, due to the structure of the smoke combination signal 1 itself, the signal light 2 on it will flip over with the smoke combination signal 1. At this time, the signal light 2 is facing upwards. Under the joint action of the switch part 2052 and the positioning part 2053, the light-emitting part 2051 will be prompted to emit light stably, helping rescuers find the person who fell into the water faster.
