Description

Technical Field

[0001] This utility model relates to the field of fire protection testing equipment technology, and more specifically, to a continuous illuminance testing device for fire protection lighting fixtures. Background Technology

[0002] Firefighting lighting fixtures, also known as fire emergency lighting fixtures, mainly refer to various lighting fixtures that provide signage and illumination for personnel evacuation and firefighting operations during a fire. The industrial enterprise building standard "Technical Standard for Fire Emergency Lighting and Evacuation Guidance Systems" GB51309-2018 stipulates that the illuminance of evacuation lighting in main passageways should not be less than 1 Lx. Fire protection codes require that emergency lighting be installed in evacuation corridors longer than 20 meters, with a minimum illuminance of not less than 3 lx and good uniformity. The continuous power supply time for emergency lighting fixtures should not be less than 20 minutes, and the evacuation lighting time should not be less than 30 minutes. For super high-rise buildings, extra-large multi-story buildings, and large hospitals, longer durations, such as 45, 60, or 90 minutes, should be considered.

[0003] Existing fire-fighting lighting fixture testing equipment has the following problems in actual use: First, most testing personnel use handheld portable lux meters to test the illuminance of fire-fighting lighting fixtures. The probes of these handheld portable lux meters are small and cannot be extended, and they are far from the lighting fixtures. Due to the complex conditions at the testing site, the light is easily blocked or reflected by temporary obstacles, resulting in a large error between the measured illuminance value and the actual value, and the testing accuracy is not good enough. Second, the entire testing process requires the testing personnel to move frequently and keep track of the time, measure the illuminance at multiple locations, and compare the uniformity. The entire testing process is time-consuming and has low testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a continuous illuminance detection device for fire-fighting lighting fixtures. This device can be directly installed below the fire-fighting lighting fixtures to be tested. Its height is adjustable, reducing the impact of temporary obstacles and ensuring the accuracy of the test data. At the same time, it can continuously detect the illuminance of multiple areas, facilitating recording and uniformity comparison, thus improving the testing efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A continuous illuminance detection device for fire-fighting lighting fixtures includes fire-fighting lighting fixtures. The power cord of the fire-fighting lighting fixture has a plug at its outer end, and the fire-fighting lighting fixture is mounted on a building wall. The plug is inserted into a power quality detector, which is inserted into a socket. The power quality detector is connected to a power supply control box via a line. A left detection plate and a right detection plate are installed between the power supply control box and the fire-fighting lighting fixture. The lower inner edge of the left detection plate has a slot running along its edge, and the lower inner edge of the right detection plate has a retaining plate running along its edge. The retaining plates are aligned and inserted into the slots, and the left and right detection plates are joined together by fixing bolts on the outer side of the slots. Telescopic brackets are provided on the lower surfaces of both the left and right detection plates. A stabilizing plate is provided at the lower end of each telescopic bracket, and a locking nut is provided on the non-telescopic section of the telescopic bracket.

[0007] As a further optimization of this solution, the inner sides of the left and right detection plates are both quarter-circular arcs and respectively wrap around the lower outer area of ​​the fire lighting fixtures from both sides. The rear ends of the left and right detection plates rest against the building wall, and several illuminance meter probes are arranged side by side at equal intervals on the inner sides of the left and right detection plates. All illuminance meter probes are connected to the power supply control box through lines.

[0008] As a further optimization of this solution, the power supply control box is equipped with a temperature and humidity sensor and a timer on the front side, an interface and a control panel on the upper surface of the power supply control box, a built-in power supply inside the power supply control box, and driving wheels on both sides of the power supply control box.

[0009] As a further optimization of this solution, the left and right detection plates can be used individually or assembled together, depending on the area illuminated by the fire-fighting lighting fixtures.

[0010] As a further optimization of this solution, the inner surfaces of the left and right detection plates are machined with grooves, and wiring channels are opened inside the grooves. The illuminance meter probe is embedded and installed inside the grooves and the wiring is routed through the wiring channels.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This utility model, by setting a left detection plate and a right detection plate and a telescopic bracket structure, can be applied to different areas of illumination of fire-fighting lighting fixtures. At the same time, the height of the left and right detection plates can be adjusted to reduce the influence of temporary obstacles, so that the light from the lamps can be completely illuminated on the surface of the detection plates and detected by several illuminance meter probes, thus ensuring the accuracy of the detection data.

[0013] In this invention, several illuminance meter probes are arranged side by side at equal intervals on the inner sides of the left and right detection plates, which realizes the zone detection of illuminance, eliminates the need for frequent movement and repositioning of the detection personnel, enables long-term continuous detection, facilitates recording and uniformity comparison, and improves detection efficiency.

The lower end of the telescopic bracket 9 is provided with a stabilizing plate seat 8. The non-telescopic section of the telescopic bracket 9 is provided with a locking nut.

[0025] like Figure 3 As shown, the inner sides of the left detection plate 4 and the right detection plate 5 are both quarter-circular arcs and wrap around the lower outer area of ​​the fire lighting fixture 1 from both sides. The rear ends of the left detection plate 4 and the right detection plate 5 are against the building wall, and several illuminance probes 10 are arranged side by side at equal intervals on the inner sides of the left detection plate 4 and the right detection plate 5. All illuminance probes 10 are connected to the power supply control box 7 through the line 3.

[0026] like Figure 5 As shown, the front side of the power supply control box 7 is equipped with a temperature and humidity sensor 18 and a timer 19, the upper surface of the power supply control box 7 is equipped with an interface 17 and a control panel 6, the power supply control box 7 has a built-in power supply, and both sides of the power supply control box 7 are equipped with driving wheels.
