Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting lamps, in particular to an embedded ground emergency lamp. Background Art

[0002] Embedded ground emergency lights (also known as fire landmark lights) are lights embedded in the ground for emergency lighting and directional indication after a fire accident occurs. Existing embedded ground emergency lights are generally consistent with the ground plane after being embedded in the ground, and people can only observe the surface of the embedded ground emergency lights. Since the luminous brightness of the embedded ground emergency lights is low and the light direction is mainly upward, only a small part of the light enters the human eye. Therefore, the embedded ground emergency lights can only be found when people approach, which is not conducive to observation. Utility Model Content

[0003] Therefore, in view of the above-mentioned problems, the present invention proposes an embedded ground emergency light, which can protrude from the ground when a fire accident occurs, so as to facilitate observation by people.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An embedded ground emergency light, comprising an embedded lamp holder, a power line, a signal line, a ring-shaped LED light panel, a controller, a lifting assembly, and a light guide lamp post;

[0006] The embedded lamp holder is provided with a groove, and the inner wall of the groove is provided with an internal thread;

[0007] The lifting assembly comprises a reduction motor and a connecting rod arranged at the bottom of the groove, wherein the connecting rod is connected to the output shaft of the reduction motor and rotates synchronously with the output shaft of the reduction motor;

[0008] The outer wall of the light guide lamp post is provided with an external thread matched with the internal thread;

[0009] The light guide lamp post is provided with a mounting hole for fixed connection with the connecting rod, and the upper surface of the light guide lamp post is provided with a fire indication pattern;

[0010] The annular LED lamp panel passes through the connecting rod and is arranged around the bottom of the light guide lamp column;

[0011] The controller is arranged at the bottom of the groove, and the controller includes a rechargeable power supply, a rectifier, a processor, an LED driving circuit module, and a reduction motor driving circuit module;

[0012] The power cord passes through the embedded lamp holder and is electrically connected to the AC input end of the rectifier, the DC output end of the rectifier is electrically connected to the rechargeable power supply, the rechargeable power supply is electrically connected to the power supply end of the processor, the signal line passes through the embedded lamp holder and is electrically connected to the communication end of the processor, the LED drive circuit module and the reduction motor drive circuit module are respectively electrically connected to the I / O end of the processor, the annular LED light panel is electrically connected to the LED drive circuit module, and the reduction motor is electrically connected to the reduction motor drive circuit module.

[0013] Furthermore, the controller is also integrated with a buzzer; the buzzer is electrically connected to the I / O terminal of the processor.

[0014] Furthermore, a human infrared sensor is disposed on the upper surface of the light guide lamp post; the human infrared sensor is electrically connected to the I / O terminal of the processor.

[0015] Furthermore, the controller is also integrated with an NFC chip and a sensing antenna; the sensing antenna is electrically connected to the communication end of the NFC chip; and the NFC chip is electrically connected to the processor.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are:

[0017] The light guide pole of this embedded ground emergency light is liftable. When in use, the signal line is connected to the fire linkage control system (this solution does not involve the improvement of the fire linkage control system. Those skilled in the art should know that the fire linkage control system is an existing device). When a fire accident occurs, the fire linkage control system sends a signal to the processor of this embedded ground emergency light. The processor controls the output shaft of the reduction motor to rotate and drive the connecting rod to rotate synchronously. The rotation of the connecting rod can control the rotation of the light guide pole to rise / fall (such as setting the connecting rod to rotate the light guide pole to rise when the connecting rod rotates forward, and the connecting rod to rotate the light guide pole to fall when the connecting rod rotates reversely). After the light guide pole rises, it is more convenient to observe because the light guide pole can emit light all over and protrude from the ground.

[0018] Furthermore, in order to prevent people from tripping when the light guide lamp column rises, a human infrared sensing sensor is set on the light guide lamp column. If a person is detected on the embedded ground emergency light, a prompt message is issued through a buzzer. The light guide lamp column will not be controlled to rotate and rise until the person leaves.

[0019] Furthermore, an NFC chip and an induction antenna are provided. When maintenance and overhaul are required, the NFC function of the mobile terminal device can be used to wirelessly connect to the embedded ground emergency light for identity verification, and then the light guide lamp pole can be controlled to rotate up or down, which is convenient for maintenance and overhaul.

[0023] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] refer to Figure 1-Figure 3 This embodiment provides a recessed ground emergency light, including a recessed lamp holder 1, a power cord ( Figure 1 and Figure 2 Not shown), signal line ( Figure 1 and Figure 2 Not shown), annular LED light board 4, controller ( Figure 1 and Figure 2 ), a lifting assembly 3, and a light guide lamp post 2.

[0025] The embedded lamp holder 1 is provided with a groove 10 , the depth of which can be set according to actual needs, and an internal thread 11 is provided on the inner wall of the groove 10 .

[0026] The light guide lamp post 2 can be made of transparent glass or acrylic plate. A mounting hole is provided in the light guide lamp post 2 (not marked in the figure, but those skilled in the art should understand the location of the mounting hole according to the specification and the drawings).

[0027] The upper surface of the light guide pole 2 is also provided with a human infrared sensor 5 for sensing whether there is a person on the light guide pole 2. It should be noted that the light guide pole 2 generally rises to a height of 3 cm to 10 cm, and the rising process is slow. People will observe when walking, and normally they will not trip people passing by.

[0028] The lifting assembly 3 includes a reduction motor 31 and a connecting rod 32 disposed at the bottom of the groove 10 . The connecting rod 32 is connected to the output shaft of the reduction motor 31 and rotates synchronously with the output shaft of the reduction motor 31 .

[0029] The outer wall of the light guide pole 2 is provided with an outer thread 21 adapted to the inner thread 11; the connecting rod 32 is fixedly connected to the mounting hole on the light guide pole 2, and the rotation of the connecting rod 32 can control the light guide pole 2 to rotate up / down (for example, the connecting rod 32 is set to rotate the light guide pole 2 up when it rotates forward, and the connecting rod 32 is set to rotate the light guide pole 2 down when it rotates reversely). The upper surface of the light guide pole 2 is provided with a fire indication pattern 22, which in this specific embodiment is a unidirectional arrow pattern, and can also be set to a double-display arrow pattern according to actual conditions.

[0030] It should be noted that lubricating oil should be applied between the internal thread 11 and the external thread 21 to facilitate the light guide lamp post 2 to rotate upward or downward.

[0031] The annular LED lamp panel 4 passes through the connecting rod 32 and is arranged around the bottom of the light guide lamp post 2 .

[0032] The controller 6 is arranged at the bottom of the groove 10 ( Figure 1 and Figure 2 The controller 6 is not shown installed at the bottom of the groove 10, but those skilled in the art should understand the setting method of the controller 6, and it should be noted that the setting of the controller 6 should not affect the rotation up or down of the light guide lamp post 2). The controller 6 includes a processor 61, a rechargeable power supply 62, a rectifier 63, an LED drive circuit module 64, a reduction motor drive circuit module 65, a buzzer 66, an NFC chip 67, and an induction antenna 68.

[0033] In this specific embodiment, preferably, the processor 61 adopts an ESP32-S3 chip, and the above-mentioned electronic components are all existing equipment. Those skilled in the art should have the conventional selection ability of the above-mentioned electronic components, and those skilled in the art can fully reproduce the embedded ground emergency light disclosed in this patent application and produce the same technical effect after a limited number of circuit connection experiments based on this specification and the drawings in the specification.

[0034] The connection method of the above electronic components is:

[0035] The power cord passes through the embedded lamp holder 1 and is electrically connected to the AC input end of the rectifier 63, and the DC output end of the rectifier 63 is electrically connected to the rechargeable power supply 62. When in use, the power cord is connected to the mains to charge the rechargeable power supply 62. It should be noted that the power cord passing through the embedded lamp holder 1 is not shown in the figure, but those skilled in the art should understand the arrangement of the power cord.

[0036] The rechargeable power source 62 is electrically connected to a power terminal of the processor 61 to supply power to the processor 61 .

[0037] The signal line passes through the embedded lamp holder 1 and is electrically connected to the communication end of the processor 61. It should be noted that the signal line passing through the embedded lamp holder 1 is not shown in the figure, but those skilled in the art should understand the setting method of the signal line.

[0038] The human infrared sensing sensor 5, LED drive circuit module 64, reduction motor drive circuit module 65, and buzzer 66 are electrically connected to the I / O terminal of the processor 61 respectively, the NFC chip 67 is electrically connected to the communication terminal of the processor 61, the sensing antenna 68 is electrically connected to the NFC chip 67, the annular LED light board 4 is electrically connected to the LED drive circuit module 64, and the reduction motor 31 is electrically connected to the reduction motor drive circuit module 65.

[0039] When using:

[0040] Connect the signal line to the fire linkage control system (this solution does not involve the improvement of the fire linkage control system, and those skilled in the art should know that the fire linkage control system is an existing device). When a fire accident occurs, the fire linkage control system sends a signal to the processor 61 of the embedded ground emergency light. The processor 61 controls the output shaft of the reduction motor 31 to rotate and drive the connecting rod 32 to rotate synchronously. The rotation of the connecting rod 32 can control the light guide post 2 to rotate and rise. After the light guide post 2 rotates and rises, it is more convenient to observe because the light guide post 2 can emit light throughout the body and protrude from the ground. When the fire accident is eliminated, the processor 61 controls the reduction motor 31 to make the light guide post 2 rotate and descend to be flush with the ground plane.

[0041] When maintenance and inspection is needed, after the NFC function of the mobile terminal device is used to conduct NFC wireless connection with the embedded ground emergency light (through the sensing antenna 68 and NFC chip 67 of the embedded ground emergency light) to verify the identity, the light guide lamp post 2 can be controlled to rotate up or down, which is convenient for maintenance and inspection.

[0042] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
