Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-5 , a safety detection device for fire-fighting electrical facilities, including a base 1, a detector is fixedly installed on the base 1 through a support column, a plurality of electric telescopic rods 2 are vertically and fixedly installed on the lower surface of the base 1, and U-shaped connecting blocks 3 are fixedly installed at the lower ends of the plurality of electric telescopic rods 2. A support block 4 is fixedly installed at the lower end of the U-shaped connecting block 3;

[0024] The support block 4 and the electric telescopic rod 2 play a role in supporting the base 1, so as to support and place the detector in the fire passage. The electric telescopic rod 2 can drive the base 1 to move up and down in the vertical direction, so as to adjust the height of the detector and realize the detection of airflows at different heights. When the height of the detector increases, the center of gravity of the overall device will increase.

[0025] Fixing blocks 5 are symmetrically and fixedly installed on the support block 4. Rack bars 6 are slidably installed on both fixing blocks 5. The two rack bars 6 are centrosymmetrically arranged on the support block 4. Extension blocks 7 are fixedly installed at one ends of the two rack bars 6. A transmission component for driving the two rack bars 6 to move away from each other is provided on the support block 4. The transmission component includes a rotating shaft 8 vertically and rotatably installed on the support block 4, a spur gear 9 fixedly sleeved on the rotating shaft 8, and a rotating component for driving the rotating shaft 8 to rotate. The upper end of the rotating shaft 8 is fixedly connected to the U-shaped connecting block 3. Both rack bars 6 are meshed with the spur gear 9. The rotating component includes a wire winding wheel 10 fixedly sleeved on the rotating shaft 8, a rope 11 wound around the wire winding wheel 10, and a torsion spring 12 fixedly installed on the wire winding wheel 10. One end of the rope 11 away from the wire winding wheel 10 is fixedly connected to the lower surface of the base 1, and one end of the torsion spring 12 away from the wire winding wheel 10 is fixedly connected to the U-shaped connecting block 3;

[0026] When the electric telescopic rod 2 drives the base 1 to move vertically upward, the distance between the base 1 and the support block 4 will increase. At this time, the base 1 will pull one end of the rope 11, and then drive the winding wheel 10 to rotate through the rope 11, thereby driving the rotating shaft 8 to rotate, and the torsion spring 12 will deform. During the rotation of the rotating shaft 8, it will drive the spur gear 9 to rotate. Since both rack bars 6 are meshed with the spur gear 9, it will drive the two rack bars 6 to move away from each other, and then drive the two expansion blocks 7 to move away from each other through the two rack bars 6. The expansion blocks 7 and the support block 4 are in contact with the ground together, playing a supporting role for the device. As the distance between the two expansion blocks 7 becomes farther, the contact area with the ground becomes larger, so that the device is supported more stably, avoiding being blown by strong air currents, and effectively improving the stability of the device;

[0027] When the height of the base 1 decreases, under the action of the torsion of the torsion spring 12, it drives the winding wheel 10 to rotate in the opposite direction, thereby winding the rope 11 around the winding wheel 10, and then drives the spur gear 9 to rotate in the opposite direction through the rotating shaft 8, driving the two expansion blocks 7 to move closer to each other.

[0028] A bracket 13 is fixedly installed at the lower end of the electric telescopic rod 2. One end of the bracket 13 is rotatably installed with a guide wheel 14. The rope 11 is sleeved on the guide wheel 14. The bracket 13 and the guide wheel 14 play a supporting role for the rope 11, ensuring that the rope 11 is in a horizontal state between the guide wheel 14 and the winding wheel 10 and in a vertical state between the guide wheel 14 and the base 1, facilitating the rope 11 to drive the winding wheel 10 to rotate.

[0029] Spherical grooves are formed on the lower surfaces of both expansion blocks 7, and support balls 15 are rotatably embedded in the spherical grooves. The expansion blocks 7 are in contact with the ground through the support balls 15. During the movement of the expansion blocks 7, rolling contact occurs between the support balls 15 and the ground, and the support balls 15 can reduce the friction between the expansion blocks 7 and the ground.

[0030] Anti-slip pads are fixedly installed on the lower surfaces of multiple support blocks 4. The anti-slip pads are made of rubber material, and the anti-slip pads can increase the friction between the support blocks 4 and the ground, further improving the stability of the device.

[0031] In the present utility model, when the electric telescopic rod 2 drives the base 1 to move vertically upward, the spur gear 9 is driven to rotate through the transmission assembly, thereby driving the two rack bars 6 to move away from each other, and then driving the two expansion blocks 7 to move away from each other through the two rack bars 6. As the distance between the two expansion blocks 7 becomes farther, the contact area with the ground becomes larger, so that the device is supported more stably, avoiding being blown by strong air currents, and effectively improving the stability of the device.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
