Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to an automatic detection device for fire fighting emergency lights. Background Art

[0002] Fire emergency lights are an important lighting device for fire prevention. When an emergency such as an earthquake or fire occurs, the main power supply is suddenly interrupted. The ordinary lighting equipment cannot continue to provide lighting due to power outage. At this time, the fire emergency lights will be activated by the built-in battery and turn on the emergency lighting. When using fire emergency lights daily, it is necessary to frequently check whether the functions are normal. In order to save energy, some fire emergency lights have light sensors integrated inside. When the power is off during the day, if the light is strong, the lights can be temporarily turned off to save electricity.

[0003] When testing the fire emergency lights, it is generally necessary to press the test button of the fire emergency lights and observe with the human eye to determine whether the fire emergency lights can work normally. However, there are generally many fire emergency lights in a building, and testing them one by one will consume a lot of manpower. In the prior art, a self-test signal of the internal circuit of the fire emergency lights is generated by a wireless receiving device and received at a terminal, so as to obtain the self-test status of all the fire emergency lights at one time. However, it is also possible that the circuit self-test passes but the actual light does not light up. Therefore, a bypass detection device is needed. A fire emergency light automatic detection device disclosed by Chinese Patent Publication No. CN214580794U integrates a camera to detect the surrounding information of the fire emergency lights, but the cost of the integrated camera is high, which is not conducive to promotion.

[0004] Therefore, a fire emergency light automatic detection device with low cost and capable of providing bypass detection is needed. Utility Model Content

[0007] Preferably, the driving device includes two groups of symmetrically arranged limit plates, each of which is an L-shaped structure. The two groups of limit plates respectively limit the up and down sliding of the connecting rod under the action of the connecting rod. A micromotor is fixedly installed on one side wall of the limit plate, and a rotating shaft is fixedly installed on the output end of the micromotor. The rotating shaft can rotate between the two groups of limit plates, and a driving gear is fixedly installed on the rotating shaft at a position corresponding to the position between the two groups of limit plates. The connecting rod is provided with a groove that meshes with the driving gear at the position corresponding to the driving gear.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment: A fire emergency light automatic detection device, such as Figure 1-Figure 3 As shown, it includes a lamp housing 1, a lamp 2 is fixedly installed on the lamp housing 1, a cover plate 3 is detachably installed on the front end surface of the lamp housing 1, a mainboard box 4 is fixedly installed inside the lamp housing 1, and the mainboard box 4 includes a power supply and a main circuit board and other structures. When the power is off, the circuit board completes a series of judgments to enable the power supply to supply power to the lamp 2, thereby realizing the emergency lighting function.

[0026] In particular, a wireless transceiver assembly 5 for wireless information reception and transmission is fixedly installed in the lamp housing 1, and the wireless transceiver assembly 5 is electrically connected to the main board box 4. An avoidance groove 6 is opened on the lamp housing 1 at a position corresponding to the front of the lamp 2, and an active light sensor 8 is clamped in the avoidance groove 6. The active light sensor 8 can slide up and down along the avoidance groove 6, and a downwardly extending connecting rod 10 is fixedly installed on the bottom end surface of the active light sensor 8. A driving device for driving the connecting rod 10 to slide up and down is also fixedly installed in the lamp housing 1, and the driving device is electrically connected to the main board box 4. When testing is required, a signal is sent to the wireless transceiver assembly 5, and the wireless transceiver assembly 5 controls the main board box 4 to cut off the main power supply of the fire emergency light, and then powers the lamp 2, and starts the driving device, so that the connecting rod 10 drives the active light sensor 8 to rise upward to the front of the lamp 2 to obtain lighting parameters, thereby judging whether the emergency fire light is normal.

[0027] In some embodiments, the driving device is an electric telescopic rod, and the output end of the electric telescopic rod is fixedly connected to the connecting rod 10, so as to control the connecting rod 10 to slide up and down.

[0028] In some embodiments, the driving device includes two groups of symmetrically arranged limit plates 9, which are L-shaped structures. The two groups of limit plates 9 act on the connecting rod 10 to limit the up and down sliding of the connecting rod 10. A micromotor 11 is fixedly installed on one side wall of the limit plate 9, and a rotating shaft 12 is fixedly installed on the output end of the micromotor 11. The rotating shaft 12 can rotate between the two groups of limit plates 9. A driving gear 13 is fixedly installed on the rotating shaft 12 at a position corresponding to the two groups of limit plates 9. A groove that meshes with the driving gear 13 is opened at the position of the connecting rod 10 corresponding to the driving gear 13. When the micromotor 11 is started, the micromotor 11 drives the driving gear 13 to rotate, thereby driving the connecting rod 10 to slide up and down between the two groups of limit plates 9.

[0029] Furthermore, the limiting plate 9 is fixedly mounted on the cover plate 3 or fixedly connected to the inner wall surface of the lamp housing 1. In a preferred embodiment, the limiting plate 9 is fixedly mounted on the cover plate 3 to facilitate removal of the entire lamp housing 1.

[0030] In other embodiments, the first magnet 14 is fixedly installed on both sides of the lower end surface of the limit plate 9, and the second magnet 15 is fixedly installed on the lower end surface of the connecting rod 10. When the active light sensor 8 rises to the front of the lamp 2, the first magnet 14 and the second magnet 15 are magnetically connected. At this time, the power failure of the micromotor 11 will not cause the active light sensor 8 to fall back.

[0031] In other embodiments, the end of the second magnet 15 extends to directly below the two sets of limit plates 9, and plays a limiting role when the connecting rod 10 continues to slide upward, thereby preventing the connecting rod 10 from sliding excessively and deviating from the normal use height.

[0032] In other embodiments, a sealing ring 16 is fixedly installed on the top surface of the active light sensor 8. The sealing ring 16 has an inverted trapezoidal structure and is made of rubber. When the active light sensor 8 is in the avoidance groove 6, the sealing ring 16 has an interference fit with the inner wall surface of the avoidance groove 6, thereby sealing the interior of the lamp housing 1 and reducing the impact of dust on the interior of the lamp housing 1.

[0033] In other embodiments, a fixed light sensor 7 is fixedly mounted on the lamp housing 1 or the cover plate 3 , and the position of the fixed light sensor 7 is fixed. The generated illumination parameters are compared with the movable light sensor 8 to increase reliability.

[0034] The working principle of the utility model is as follows: when a test is required, a signal is sent to the wireless transceiver assembly 5, the wireless transceiver assembly 5 controls the mainboard box 4 to cut off the main power supply of the fire emergency light, and then supplies power to the lamp 2, and starts the driving device, so that the connecting rod 10 drives the active light sensor 8 to rise upward to the front of the lamp 2, obtains the lighting parameters, thereby judging whether the emergency fire light is normal, and then sends it to the terminal through the wireless transceiver assembly 5, which saves manpower and does not increase the high production cost.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
