Technical Field
[0001] The utility model relates to the technical field of fire detection equipment, and more specifically, to a detection component for the end power distribution device of a fire smoke prevention and exhaust system. Background Art
[0002] The end power distribution device of a fire smoke prevention and exhaust system is an important power supply device in the fire smoke prevention and exhaust system. Its core function is to perform dual power supply (manual or automatic) conversion. In terms of the installation quality inspection, the installation requirements of the end power distribution device first require that the environment should be kept dry. Secondly, if it is installed on the wall, the bottom edge should be 1.3 - 1.5 meters from the ground (floor) surface. The side close to the door hinge should be no less than 0.5 meters from the door hinge, and the front operation distance should be no less than 1.2 meters. If it is installed on the ground, the bottom edge should be 0.1 - 0.2 meters higher than the ground (floor) surface, mainly for waterproof consideration. In terms of the internal safety inspection, the end power distribution device usually contains electrical components such as circuit breakers, switches, indicator lights, and protection devices. In addition to detecting whether the outside and wiring of the electrical components are damaged, it is also necessary to detect whether the electrical components are damp or overheated.
[0003] In the existing inspection work, the staff generally uses a tape measure to detect whether the installation position of the end power distribution device meets the requirements. The measurement work takes a long time and is affected by various factors during the manual measurement process, resulting in a large measurement error. For the humidity outside and inside the end power distribution device, most of them are judged and filled in the inspection form by observation experience, without specific data support, reducing the inspection reliability and making it difficult to detect electrical component faults in a timely manner. Content of the Utility Model
[0004] The purpose of the utility model is to provide a detection component for the end power distribution device of a fire smoke prevention and exhaust system. On the one hand, this detection component can quickly detect the installation quality of the end power distribution device, and at the same time, it can conveniently detect the temperature and humidity at various positions outside and inside the end power distribution device, display the data in real time, improve the reliability of the inspection work, and be able to detect electrical component faults in a timely manner.
[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0006] A detection component for the end power distribution device of a fire smoke prevention and exhaust system, including a door frame arranged on the wall. An end power distribution device is installed on the wall surface on one side of the door frame. The end power distribution device is connected upward to the electrical equipment of the fire smoke prevention and exhaust system through a wire conduit. A detection component is arranged on one side of the end power distribution device. The detection component includes an L-shaped bracket. A longitudinal through groove is opened at the lower end in the middle position of the horizontal section of the L-shaped bracket, and an L-shaped measuring scale passes through the inside of the through groove. The length of the horizontal section of the L-shaped measuring scale is greater than 1.2 meters, and the vertical section of the L-shaped measuring scale abuts against the wall surface. The L-shaped bracket fixes the L-shaped measuring scale inside the through groove with bolts. A support plate is arranged upward at the outer end of the horizontal section of the L-shaped bracket.
[0007] As a further optimization of this solution, a horizontal mounting plate is arranged at the upper end of the vertical section of the L-shaped bracket. An arc-shaped sliding track is arranged between the mounting plate and the support plate. The cross-section of the sliding track is H-shaped, and a measuring component is slidably mounted on the sliding track. A temperature and humidity sensor is arranged above the mounting plate. A wire management groove is arranged on the rear side of the temperature and humidity sensor. The temperature and humidity sensor is connected to a detection probe through a wire, and the excess length of the wire is placed inside the wire management groove.
[0008] As a further optimization of this solution, the measuring component includes a laser rangefinder. Laser probes are arranged on both sides at the lower end of the laser rangefinder. One side surface of the laser rangefinder is connected to one side surface of a clamping plate through a support column. Rotating shafts are arranged on both sides between the clamping plates, and rollers are rotatably sleeved on the rotating shafts. The rollers are slidably embedded on the sliding track. A moving handle is arranged outward on the other side surface of the clamping plate.
[0009] As a further optimization of this solution, the height of the support plate is less than 0.1 meter, and the length of the vertical section of the L-shaped bracket is greater than 1.3 meters.
[0010] As a further optimization of this solution, the measuring component slides to the positions between the end power distribution device and the door frame and between the end power distribution device and the ground respectively.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In the present utility model, by setting a structure of a measuring component that can move freely, the laser probes on both sides can be moved to the positions to be detected, and the distances below and on the side of the end power distribution device installed on the wall or on the ground can be measured respectively for installation quality detection. The data is displayed on the display of the laser rangefinder, which improves the efficiency of the detection work. At the same time, compared with manual tape measurement, the obtained data is more accurate and reliable. The L-shaped measuring scale is used to detect whether the front of the end power distribution device meets the minimum operating distance.
[0013] In the present utility model, by providing a cable management groove and a temperature and humidity sensor structure, the inspector can hold the detection probe and directly detect the temperature and humidity at various positions outside and inside the terminal power distribution device, which is directly displayed on the display of the temperature and humidity sensor to detect whether the electrical components are damp or overheated, and timely discover the faults of the electrical components.
