Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Aiming at the existing lighting lighthouse, the four-corner electric adjusting telescopic rod is adopted as the support frame of the whole device, and in the practical use, any one of the four corners electric adjusting telescopic rod and the ground easily form the problem of small ground clearance, the embodiment provides an automatic adjusting mechanism of lifting support legs, which is applicable to YDZY-M2012 automatic lighting lighthouse devices, YDZY-M0012 automatic lighting lighthouse devices, YDZY-M0022 automatic lighting lighthouse devices and M2500 automatic waterlogging drainage lighting devices produced by Shenzhen Shanghai lighting technology limited company.

Specifically, as shown in fig. 1, the automatic lifting leg adjusting mechanism includes lifting legs having four corners formed by electric adjusting telescopic rods 1, the electric cylinders of the electric adjusting telescopic rods 1 are respectively connected with a relay 2, a level 3 is further installed on the lifting legs, and the level 3 is installed inside the box body of the lifting legs, which is not shown in fig. 1. Spirit level 3 is connected with the electric regulation telescopic link 1 in lift landing leg four corners through four relays 2 respectively, and spirit level 3 cooperates corresponding relay 2 to produce the signal of telecommunication when the lift landing leg inclines, and corresponding relay 2 adjusts lift landing leg to horizontality through the corresponding electric regulation telescopic link 1 of signal of telecommunication control.

As shown in fig. 2, in the level 3 of the present embodiment, a box body is provided with groove slides 4 which are diagonally crossed, a sealing shell is installed on the top of the groove slides 4, and mercury drops 5 are arranged in the groove slides 4; four groups of annular fracture wires 6 are further arranged inside the box body of the level meter 3, two ends of each group of annular fracture wires 6 respectively extend into the slideways on two sides, and two adjacent groups of annular fracture wires 6 are connected with the relays 2 at corresponding angles. Each group of annular fracture wires 6 comprises a plurality of metal wires with arc-shaped sections extending outwards at equal intervals by taking the center of the box body as the circle center, and the interval between the metal wires is smaller than the section diameter of the mercury drops 5.

The working principle of the automatic adjusting mechanism for the lifting supporting leg is as follows:

as shown in fig. 2, when the electric adjusting telescopic rods 1 at the B and C corners of the lifting leg are the same in extension and retraction, the electric adjusting telescopic rods 1 at the a and D corners are different in extension and retraction, and when the electric adjusting telescopic rods 1 at the D corner are large in extension and retraction, the bottom of the electric adjusting telescopic rods 1 at the a corner form a small ground clearance with the ground; the lighthouse device is inclined towards the side of the A corner. At this time, the mercury drop 5 in the groove slideway 4 of the level 3 slides to the A angle side, and because the mercury has conductivity, the corresponding section of metal wire in the two adjacent groups of annular broken leads 6 at the staying position of the mercury drop 5 forms electric connection through the mercury drop 5; the relays 2 at the A corners connected with the two adjacent groups of annular fracture wires 6 can generate electric signals, and the relays 2 at the A corners control the electric adjusting telescopic rods 1 at the A corners to carry out micro-extension adjustment; after the telescopic amount of the electric adjusting telescopic rod 1 at the angle A is consistent with the telescopic amount of the electric adjusting telescopic rod 1 at the angle D, the mercury drops 5 flow back to the central position of the diagonal crossed groove slideway 4, corresponding sections of metal wires in the two adjacent groups of annular broken wires 6 are disconnected, electric signals disappear, and the electric adjusting telescopic rod 1 at the angle A stops stretching.

Based on the principle, if the telescopic amount of the electric adjusting telescopic rod 1 at the B angle and the C angle is inconsistent after the first adjustment, the mercury drops 5 in the level meter 3 still can generate offset, and the relay 2 at the corresponding angle controls the corresponding electric adjusting telescopic rod 1 to adjust the lifting supporting leg to the horizontal state through an electric signal.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
