Description

Technical Field

[0001] This utility model relates to the field of fire protection electrical facility safety technology, specifically a safety testing device for fire protection electrical facilities. Background Technology

[0002] Fire protection electrical facilities are key equipment in buildings used for the prevention, monitoring, and extinguishing of fires. Their design and operation are directly related to the safety and effectiveness during a fire, providing reliable fire protection for the building. Fire protection electrical facility safety testing devices are specialized tools used to monitor and assess the safety of electrical equipment and wiring in buildings, aiming to prevent electrical fires.

[0003] According to announcement number CN221491345U, a safety testing device specifically for fire-fighting electrical facilities includes a main body, a support mechanism, and a fixing mechanism. The support mechanism is located at the lower end of the main body, and the fixing mechanism is located on the left and right sides of the support mechanism. The main body includes a mounting frame, with a sliding groove fixedly formed in the middle of the mounting frame. A threaded rod is rotatably connected to the inner wall of the sliding groove, and a control handle is fixedly connected to one end of the threaded rod. A limit plate is slidably connected to the middle of the sliding groove. This safety testing device for fire-fighting electrical facilities, by setting a limit plate inside the mounting frame and threadedly connecting the limit plate to the outer surface of the threaded rod, allows the threaded rod to rotate when the control handle is rotated. Simultaneously, the two limit plates move relative to each other, clamping the testing instrument. A first spring prevents excessive force from damaging the testing instrument, thus improving the protection capability of the testing instrument.

[0004] However, the aforementioned patent fixes the detector to the top of the mounting bracket without protecting it, which results in the detector being exposed to the outside world during both working and rest periods. Furthermore, the detector is a relatively delicate electronic device, and when staff leave the detector during rest periods, it is prone to collisions with external debris and damage, thus affecting the use of the safety detection device.

[0021] Please see Figures 1-6This utility model provides a technical solution: a safety testing device specifically for fire-fighting electrical facilities, comprising a base 1, a testing device body 4, and a protective mechanism 6. A base 2 is welded to the outer wall of the top of the base 1, and a protective box 3 is connected to the top of the outer wall of the base 2. The testing device body 4 is connected inside the protective box 3. A caster wheel 5 is installed on the outer side of the bottom of the base 1. The protective mechanism 6 includes a worm gear 601, a worm wheel 602, a threaded rod 603, a threaded seat 604, a transmission plate 605, a lifting seat 606, a slide rail 607, a threaded column 608, and a transmission... The base 2 comprises a moving seat 609, a support plate 610, a support base 611, and a limiting plate 612. A worm gear 601 is rotatably connected to one side of the bottom end of the base 2. A worm wheel 602 is meshed with the middle of the outer wall of the worm gear 601. A threaded rod 603 is welded to the top of the outer wall of the worm wheel 602. A threaded seat 604 is threadedly connected to the middle of the outer wall of the threaded rod 603. A transmission plate 605 is welded to both sides of the top of the threaded seat 604. A lifting seat 606 is welded to the top of the outer wall of the transmission plate 605. The top of the lifting seat 606 is connected to the bottom of the main body 4 of the detection device. The outer wall of the lifting seat 606... The protective box 3 is equipped with sliding rails 607 on both sides, and one side of the outer wall of the sliding rail 607 is welded to the inner wall of the protective box 3. The top of the protective box 3 has an opening for movement. The top of the threaded rod 603 is connected to the protective box 3 through a bearing seat. The threaded seat 604 and the transmission plate 605 have a "U" shaped structure. The bottom of the worm gear 602 is welded with a threaded post 608, and the middle of the outer wall of the threaded post 608 is threadedly connected to the transmission seat 609. The bottom of the threaded post 608 is connected to the base 1 through a bearing seat. The outer walls of the transmission seat 609 are rotatably connected to support plates 610, and the support plates 610 are rotatably connected to the two sides of the outer wall of the transmission seat 609. The bottom end of the base 1 is rotatably connected to a support base 611, and a limiting plate 612 is welded to the middle of the outer wall of the support base 611; the bottom end of the support base 611 is connected to a second universal wheel 7, the bottom end of the base 1 has an open movable groove, and the limiting plate 612 extends into it, and the support plate 610 is distributed in a figure-eight shape; the middle part of the base 1 has limiting grooves on both sides, and the outer walls of the transmission seat 609 extend into them, and the support base 611 and the limiting plate 612 form a “T” structure; the center line of the threaded rod 603 and the threaded column 608 coincides, and the protective box 3 has a storage cavity inside.

[0022] In specific implementation, during the safety inspection of fire-fighting electrical facilities using a safety inspection device, when it is necessary to protect the main body 4 of the inspection device during a break, first rotate the worm 601. Because the worm 601 and worm wheel 602 are meshed, the rotation of the worm 601 will drive the worm wheel 602 to rotate. Since the worm wheel 602 is connected to the threaded rod 603 and the threaded post 608, the rotation of the worm wheel 602 will drive the threaded rod 603 and the threaded post 608 to rotate together. Then, the rotation of the threaded rod 603 will generate a downward thrust on the threaded seat 604, causing the threaded seat 604 to drive the transmission plate 605 to move downward. The transmission plate 605 is connected to the lifting seat 606. When the transmission plate 605 moves, it will drive the lifting seat 606 to move together. Since the lifting seat 606 is connected to the main body 4 of the detection device, when the lifting seat 606 moves along the slide rail 607, it will drive the main body 4 of the detection device to move together until the lifting seat 606 drives the main body 4 of the detection device to be stored in the protective box 3. At this time, the protective box 3 protects the main body 4 of the detection device during the rest period, preventing the main body 4 of the detection device from being damaged by collision with external debris during the rest period. In addition, the worm 601 and the worm wheel 602 have a self-locking effect, which can prevent the lifting seat 606 and the transmission seat 609 from moving at will.

[0023] Because the threaded column 608 and the transmission seat 609 are connected by threads, the rotation of the threaded column 608 will generate an upward thrust on the transmission seat 609, causing the transmission seat 609 to move upward. Since the transmission seat 609 and the support plate 610 are rotatably connected, the movement of the transmission seat 609 will drive the support plate 610 to rotate. At this time, the included angle between the support plate 610 and the transmission seat 609 will change, which will generate a pulling force on the support seat 611, causing the support seat 611 to drive the second universal wheel 7 to move closer to the base 1. Since the support seat 611 is connected to the limiting plate 612, the limiting plate 612 will slide along the base 1, thereby guiding the movement of the support seat 611 to move smoothly until the support seat 611 is in contact with the base 1, thereby reducing the space occupied by the support seat 611 and making it convenient for staff to store the safety detection device.

[0024] When the main body 4 of the testing device needs to be extended out of the protective box 3 for operation, the worm gear 601 is first rotated to drive the worm wheel 602 to rotate. Then, the rotation of the threaded rod 603 will generate an upward thrust on the threaded seat 604 until the lifting seat 606 drives the main body 4 of the testing device to move out of the protective box 3. At this time, the rotation of the threaded seat 604 will generate a downward thrust on the transmission seat 609, which in turn generates a thrust on the support seat 611, causing the support seat 611 to drive the second universal wheel 7 to move away from the base 1. This increases the support area between the testing device and the ground, improves the support stability of the testing device, and thus plays a role in facilitating the protection of the testing device and providing auxiliary support during operation when used in a fire protection electrical facility safety testing device.

[0025] In summary, when using this safety testing device for fire-fighting electrical facilities, the base 1 is first moved by the first universal caster 5. Then, the base 1 moves, driving the protective box 3 to move together through the base 2 until the main body 4 of the testing device on top of the protective box 3 reaches the designated position. At this time, the main body 4 of the testing device, in conjunction with temperature sensors and infrared technology, monitors the temperature of electrical circuits and equipment in real time, and promptly detects potential overheating hazards. This is existing technology and will not be elaborated on here. The lifting seat 606 of the protective mechanism 6 moves the main body 4 of the testing device until it is housed in the protective box 3 for protection, thereby preventing the main body 4 of the testing device from being damaged by collisions with external debris during rest periods. When the testing device is working, the support seat 611 moves away from the base 1, thereby increasing the support area between the testing device and the ground and improving the support stability of the testing device. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
