Description

Technical Field

[0001] This invention belongs to the technical field of fire protection equipment, and in particular relates to a device that can continuously monitor emergency lighting fixtures for a long time. Background Technology

[0002] Emergency lighting fixtures are a type of lighting equipment that effectively illuminates and displays evacuation routes when normal lighting power fails, or provides continuous, uninterrupted illumination. They are widely used in public places and areas where uninterrupted lighting is unacceptable. Emergency lighting fixtures consist of several parts, including a light source, a light source driver, a rectifier, an inverter, a battery pack, and a marker light housing. Normally, 36V power drives the light source driver for illumination, while the rectifier replenishes the battery pack. Even when the lights are turned off after get off work, the rectifier continues charging to keep the battery pack fully charged. In an emergency, when the mains power suddenly fails, the inverter automatically activates its inverter circuit, converting the low-voltage energy from the battery pack into high-voltage energy to drive the light source for continued illumination. Evacuation emergency lighting and marker lights, collectively known as fire emergency lighting fixtures, are an important product required by fire safety measures. Normally, it provides illumination like a regular light fixture. However, in emergencies such as earthquakes, fires, or sudden power outages caused by electrical faults, when all other light sources cease operation, it must immediately provide reliable lighting and indicate the direction of evacuation and the location of emergency exits to ensure the safe evacuation of those stranded in darkness. Therefore, emergency lighting is a light source that maintains illumination and guides evacuation in emergency situations.

[0003] Therefore, emergency lighting fixtures generally require weekly inspections to check their functionality and duration of illumination, ensuring normal operation. National maintenance requirements dictate weekly checks of charging status and monthly discharge tests. Fixtures with a discharge time less than 30 minutes should be repaired or replaced promptly. Backup power supply time should be no less than 30 seconds, and illumination brightness should be no less than 0.8 lux. Since these fixtures are typically installed high up, inspections are cumbersome. Brightness testing, requiring multiple measurements with a lux meter, is also inefficient and time-consuming. Therefore, we aim to develop a testing device that can be installed on emergency lighting fixtures to monitor brightness and illumination time, reducing the workload of maintenance personnel. This necessitates a device capable of continuous, long-term monitoring of emergency lighting fixtures to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a device capable of continuously detecting emergency lighting fixtures over extended periods. This addresses the problems mentioned in the background art, such as the inconvenience, low efficiency, and time-consuming nature of existing emergency lighting fixture testing methods. Furthermore, it solves the problem that existing technologies do not combine the detection of both brightness and illumination time.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A device capable of continuously detecting emergency lighting fixtures over a long period of time includes an emergency lighting fixture body and a housing with an open left end that cooperates with the emergency lighting fixture. An L-shaped first support rod is vertically slidably connected inside the housing. The lower end of the first support rod is placed inside the housing and is rotatably connected to an adjusting pin that is threaded into the housing. The front end of the first support rod is longitudinally slidably connected to an L-shaped second support rod. A rectangular hole is longitudinally opened at the upper end of the housing. The second support rod is longitudinally slidably connected inside the rectangular hole. The upper surfaces of the two sets of support rods are flush and both are connected to a crossbar. The left end of the crossbar has a groove that cooperates with the lamp support rod on the emergency lighting fixture.

[0007] The left end of the housing is laterally slidably connected to a U-shaped plate. A first gear and a second gear rotate longitudinally within the housing, with the first gear positioned above the second gear. A sector gear, longitudinally rotatably connected within the housing, meshes between the first and second gears. The sector gear is coaxially connected via the output shaft of a drive motor installed within the housing. A third gear is coaxially mounted on the second gear. A first rack, meshing with the third gear, is laterally mounted at the lower end of the U-shaped plate. The first gear is connected to a triggering device, enabling the second gear's drive triggering device to activate the emergency lighting test button. A lux meter is installed on the U-shaped plate. A power transmission structure is provided between the U-shaped plate and the housing, allowing the power transmission structure to drive the lux meter to move vertically. An electromagnetic light-shielding door is installed on the lux meter.

[0008] An alarm is installed inside the housing, and the alarm, drive motor, illuminometer, and electromagnetic light-shielding door are all electrically connected to a controller installed inside the housing.

[0009] Preferably, the triggering device includes a drive plate that is laterally slidably connected to the upper end of the housing and positioned above the first gear. A first spring is connected between the left end of the drive plate and the housing, and a sleeve is installed at the right end. The right end of the sleeve is laterally slidably connected to a trigger rod that cooperates with the test button on the emergency lighting lamp. A second spring is connected between the trigger rod and the inner bottom surface of the sleeve. A third rack that meshes with the first gear is installed at the lower end of the drive plate.

[0010] Preferably, the power transmission structure includes a second rack mounted laterally within the housing, and a fourth gear and a fifth gear longitudinally rotatably connected within the U-shaped plate and arranged from left to right. The fifth gear meshes with the second rack. It also includes a cylinder rotatably connected vertically within the U-shaped plate, with a screw threaded into the upper end of the cylinder. An inclined illuminance meter is mounted on the upper end of the screw, and a limit groove is formed along the axial direction of the screw. A limit rod that slides vertically through the limit groove is formed on the U-shaped plate. A first bevel gear is coaxially mounted outside the cylinder, and a second bevel gear meshing with the first bevel gear is coaxially mounted on the fourth gear. The shafts of the fourth and fifth gears are connected by a belt for transmission.

[0011] Preferably, a rubber block is provided at the end of the slot.

[0012] The beneficial effects of this invention are as follows: This invention features a housing structure with slots on two sets of laterally sliding support rods that engage with the support rods of the emergency lighting lamp. This allows for detachable installation on the emergency lighting lamp, facilitating repeated use. An adjusting pin adjusts the vertical position. A U-shaped plate is located at one end of the housing. The sector gears on the U-shaped plate sequentially drive the first and second gears to rotate. The first gear triggers a detection button via a trigger device, and the second gear drives the U-shaped plate laterally through a rack and pinion mechanism. This lateral movement of the U-shaped plate, via a power transmission structure, adjusts the vertical position of the illuminance meter. Under normal operating conditions, without affecting the lamp's normal use, the illuminance meter's lateral and vertical positions are adjusted during testing to measure the lamp's brightness and lighting time. This invention offers convenient and simple testing, flexible disassembly, and easy repeated use, reducing the workload of testing personnel. It is easy to operate, fully automated, highly efficient, practical, and suitable for widespread application. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-11 The specific embodiments of the present invention will be described in further detail.

[0026] Example 1: Based on existing technology, a device capable of continuously monitoring an emergency lighting fixture 1 for an extended period includes the main body of the emergency lighting fixture 1 and a housing 2 with an open left end that cooperates with the emergency lighting fixture. An L-shaped first support rod 3 is vertically slidably connected within the housing 2, allowing the first support rod 3 to move only vertically. The lower end of the first support rod 3 rests within the housing 2 and is rotatably connected to an adjusting pin 4 threadedly engaged with the housing 2. The threaded engagement between the adjusting pin 4 and the housing 2 allows the user to adjust the vertical position of the first support rod 3. An L-shaped second support rod 5 is longitudinally slidably connected to the front end of the first support rod 3. The front end of the first support rod 3 has a rectangular groove structure into which the second support rod 5 is inserted. The housing 2 has a rectangular hole 6 at its upper end, which is slidably connected to the second support rod 5 in the longitudinal direction relative to the first support rod 3. The upper ends of the two sets of support rods are flush and connected to the crossbar 7. The left end of the crossbar 7 has a slot 8 that cooperates with the lamp support rod on the emergency lighting lamp. A rubber block 32 is provided at the end of the slot 8. The slot 8 on the crossbar 7 clamps the support rod on the lighting lamp, thereby locking the first support rod 3 and the second support rod 5 into the slot 8. At the same time, with the adjustment pin 4, the cooperation between the housing 2 and the first support rod 3 and the second support rod 5 locks the emergency lighting lamp 1 onto the housing 2. The disassembly and installation are also very convenient and quick.

[0027] The left end of the housing 2 is laterally slidably connected to a U-shaped plate 9. The U-shaped plate 9 can be slidably connected to the left end of the housing 2 by means of a slide rail. To prevent the U-shaped plate 9 from detaching from the left end of the housing 2, a limit stop can be set at its end. Inside the housing 2, a first gear 10 and a second gear 11 rotate longitudinally. The shafts of the first gear 10 and the second gear 11 are arranged in the longitudinal direction. The first gear 10 is positioned above the second gear 11. A sector gear 12, longitudinally rotatably connected inside the housing 2, meshes between the first gear 10 and the second gear 11. The rotation of the sector gear 12 can sequentially drive the first gear 10 and the second gear 11 to rotate. During the rotation of gears 10 and 11, they drive either the first gear 10 or the second gear 11 to rotate. The sector gear 12 is coaxially connected to the output shaft of the drive motor 13 installed in the housing 2. The sector gear 12 only serves to intermittently drive the first gear 10 and the second gear 11. The second gear 11 is coaxially mounted with a third gear 14. A first rack 15 that meshes with the third gear 14 is horizontally mounted at the lower end of the U-shaped plate 9. The cooperation between the third gear 14 and the first rack 15 can drive the U-shaped plate 9 from the left end of the housing 2, thereby adjusting the lateral position of the U-shaped plate 9. The first gear 10 is connected to a triggering device, which triggers the test button 16 of the emergency lighting lamp to satisfy the drive triggering device of the second gear 11. The first gear 10 presses the test button 16 of the emergency lighting fixture via a triggering device. Pressing the test button 16 disconnects the mains power to the emergency lighting fixture 1 and then supplies power through an internal battery, simulating the illumination of the emergency lighting fixture 1 under power failure. Specifically, the triggering device includes a drive plate 18 laterally slidably connected to the upper end of the housing 2 and positioned above the first gear 10. The housing 2 has a perforated structure with grooves on both sides, allowing the drive plate 18 to slide within the perforated and grooved structures, enabling it to move laterally only along the perforated structure. The lower end of the drive plate 18 is fitted with a mechanism that meshes with the first gear 10. The third rack 33 is connected to the drive plate 18. A first spring 19 is connected between the left end of the drive plate 18 and the housing 2. The first spring 19 serves as a reset mechanism. A sleeve 20 is installed on the right end of the sleeve 20. The right end of the sleeve 20 is laterally slidably connected to a trigger rod 21 that cooperates with the test button 16 on the emergency lighting lamp. A second spring 22 is connected between the trigger rod 21 and the inner bottom surface of the sleeve 20. The trigger rod 21, the sleeve 20, and the second spring 22 form a telescopic trigger rod 21 structure. This structure is used to press the test button when the drive plate 18 moves the trigger rod 21, thereby driving the test. A lux meter 17 is installed on the U-shaped plate 9. A power transmission structure is provided between the U-shaped plate 9 and the housing 2.The illuminance meter 17 is driven vertically by a power transmission structure. The illuminance meter 17 can be raised from the U-shaped plate 9 via this structure. The illuminance meter 17 is used to detect the brightness of the emergency lighting fixture 1 and calculate the irradiation time. The illuminance meter 17 is equipped with an electromagnetic light-shielding door. This door is used to shield the illuminance meter 17 after the detection is complete, preventing prolonged irradiation from affecting its accuracy. Because during the calculation of the irradiation time, it is not necessary to keep the illuminance meter 17 continuously open; it only needs to be opened within a specified time to re-detect the brightness of the lighting fixture, thus obtaining the irradiation time and achieving the desired detection effect.

[0028] An alarm is installed inside the housing 2. The alarm, drive motor 13, illuminance meter 17, and electromagnetic light shield are all electrically connected to a controller installed inside the housing 2. The controller is made of an integrated chip and controls the operation and status of each device. This is existing technology and will not be described in detail. The controller can be set with a switch to control the operation of the entire device, or it can be set with an infrared sensor, similar to the setting method of a remote control. Because the emergency lighting fixture 1 is generally set at a high height, we can remotely detect and turn the entire device on and off.

[0029] In this embodiment, before installing the emergency lighting fixture 1, the housing 2 is first installed below the emergency lighting fixture 1. The relative positions of the first support rod 3 and the second support rod 5 are adjusted to change their longitudinal distance, aligning it with the distance between the support rods on the emergency lighting fixture. Then, the slots 8 on the crossbars 7 of the first and second support rods 3 and 5 are engaged with the support rods on the lighting fixture. After engagement, the vertical positions of the first and second support rods 3 and 5 are adjusted by turning the adjusting pin 4, ensuring the housing 2 is securely positioned below the lighting fixture. After adjustment and installation, the emergency lighting fixture 1 is installed. When it is necessary to test the brightness and illumination time of the emergency lighting fixture 1, it can be controlled remotely. The device operates, causing the drive motor 13 to operate. The operation of the drive motor 13 causes the sector gear 12 to operate, which in turn drives the first gear 10 to operate. The rotation of the first gear 10 drives the third rack 33 to move the drive plate 18 laterally. The detection circuit is activated by triggering the detection button via the trigger rod 21. Once the sector gear 12 disengages from the first gear 10, the trigger rod 21 resets the drive plate 18 under the action of the first spring 19. Then, the sector gear 12 drives the second gear 11 to operate, which in turn drives the third gear 14 to operate. The third rack 33 then drives the first rack 15 to move, thereby moving the U-shaped plate 9 out from the left side of the housing 2 and adjusting the lateral position of the U-shaped plate 9. The U-shaped plate 9 is moved relative to the housing 2, causing the illuminance meter 17 to rise and reach the detection position. The illuminance of the lighting fixture is then measured. After the measurement, the controller closes the electromagnetic light-shielding door to protect the illuminance meter 17. The measured data is recorded in the controller. After 30 minutes, the controller opens the electromagnetic light-shielding door and performs another brightness measurement to check if the lighting fixture's brightness lasts for 30 minutes and what the brightness is like after 30 minutes. The data is recorded in the controller. After the measurement is complete, the controller controls the drive motor 13 to operate. The drive motor 13 drives the sector gear 12 to rotate in the opposite direction, retracting the U-shaped plate 9 and the illuminance meter 17 back into the housing. Inside body 2, the sector gear 12 then drives the first gear 10 to work again, causing the trigger rod 21 to press the detection button again, turning off the detection system and restoring the lighting fixture to normal operation. Since the first gear 10 and the third rack 33 are about to mesh, pushing the first gear 10 in the opposite direction will not drive the third rack 33 to move. It should be noted that the on and off state of the detection button can be adjusted by controlling the driving sequence of the sector gear 12. This embodiment is convenient and simple to use, can be flexibly disassembled, and is easy to reuse, saving the workload of the testing personnel. It is easy and simple to operate, fully automated, highly efficient, practical, and suitable for widespread use.

[0030] In Embodiment 2, based on Embodiment 1, the power transmission structure includes a second rack 23 horizontally mounted within the housing 2, and a fourth gear 24 and a fifth gear 25 longitudinally rotatably connected within the U-shaped plate 9 and arranged from left to right. The fifth gear 25 meshes with the second rack 23. It also includes a cylinder 26 vertically rotatably connected within the U-shaped plate 9, with a screw 27 threaded onto its upper end. An inclined illuminance meter 17 is mounted on the upper end of the screw 27. The screw 27 has an axially oriented limit groove 28, and the U-shaped plate 9 has a limit rod 29 that slides vertically with the limit groove 28. The engagement of the limit groove 28 and the limit rod 29 prevents the screw 27 from rotating. The cylinder 26 is coaxial with the outside. The first bevel gear 30 is installed, and the second bevel gear 31, which meshes with the first bevel gear 30, is coaxially installed with the fourth gear 24. The shafts of the fourth gear 24 and the fifth gear 25 are connected by a belt for transmission. In this embodiment, the relative lateral movement between the U-shaped plate 9 and the housing 2 causes the second rack 23 to mesh with the fifth gear 25 and rotate, driving the fourth gear 24 to rotate. The fourth gear 24 drives the sleeve 20 to rotate through the transmission of the bevel gear set. Since the lead screw 27 cannot rotate, the rotation of the sleeve 20 drives the lead screw 27 to adjust its position in the vertical direction, so that when the U-shaped plate 9 is opened, the illuminance meter 17 rises and when the U-shaped plate 9 is closed, the illuminance meter 17 retracts.

[0031] In use, before installing the emergency lighting fixture 1, the housing 2 is first installed below the emergency lighting fixture 1. The relative positions of the first support rod 3 and the second support rod 5 are adjusted to change their longitudinal distance, aligning it with the distance between the support rods on the emergency lighting fixture. Then, the slots 8 on the crossbars 7 of the first and second support rods 3 and 5 are engaged with the support rods on the lighting fixture. After engagement, the vertical positions of the first and second support rods 3 and 5 are adjusted by turning the adjusting pin 4, ensuring the housing 2 is properly positioned below the lighting fixture. After adjustment and installation, the emergency lighting fixture 1 is installed. When it is necessary to test the brightness and illumination time of the emergency lighting fixture 1, the control can be activated via remote control. The operation of the drive motor 13 causes the sector gear 12 to operate, which in turn drives the first gear 10. The rotation of the first gear 10 drives the third rack 33 to move the drive plate 18 laterally. The detection circuit is activated by triggering the detection button via the trigger rod 21. Once the sector gear 12 disengages from the first gear 10, the trigger rod 21 resets the drive plate 18 under the action of the first spring 19. Then, the sector gear 12 drives the second gear 11, which in turn drives the third gear 14. The third rack 33 then moves the first rack 15, thereby moving the U-shaped plate 9 out from the left side of the housing 2. The lateral position of the U-shaped plate 9 is adjusted to... Upon reaching the detection position, simultaneously, as the U-shaped plate 9 moves relative to the housing 2, the second rack 23 meshes with the fifth gear 25 and rotates, driving the fourth gear 24 to rotate. The fourth gear 24, through the transmission of the bevel gear set, drives the sleeve 20 to rotate. Since the lead screw 27 cannot rotate, the rotation of the sleeve 20 drives the lead screw 27 to adjust its position in the vertical direction, thereby reaching the detection position to detect the brightness of the lighting fixture. After the detection is completed, the controller controls the electromagnetic light shield to close, protecting the brightness meter 17. The detection data is recorded in the controller. After thirty minutes, the controller opens the electromagnetic light shield and performs the brightness detection again to see if the brightness of the lighting fixture lasts for thirty minutes and beyond. The brightness level is then recorded in the controller. After the test is complete, the controller controls the drive motor 13 to operate. The drive motor 13 drives the sector gear 12 to rotate in the reverse direction, retracting the U-shaped plate 9 and the illuminance meter 17 into the housing 2. Then, the sector gear 12 pushes the first gear 10 again, causing the trigger lever 21 to press the detection button again, shutting down the detection system and restoring the lighting fixture to normal operation. Since the first gear 10 and the third rack 33 are about to mesh, pushing the first gear 10 in the reverse direction will not drive the third rack 33 to move. It is important to note that the on / off state of the detection button can be adjusted by controlling the driving sequence of the sector gear 12.This invention offers convenient and simple testing, allows for flexible disassembly and reuse, reduces the workload of testing personnel, is easy to operate, features fully automated testing, high testing efficiency, and strong practicality, making it suitable for widespread use.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
