The invention discloses a protective device capable of being installed conveniently for an ascend operation vehicle. The protective device comprises a support platform, clamping blocks and stand columns. The support platform is provided with first connecting grooves and second connecting grooves separately, and the first connecting grooves are located on the outer sides of the second connecting grooves. Vertical rods are installed on the inner sides of the second connecting grooves, and the clamping blocks are located inside mounting grooves. Return springs are installed on the outer sides ofthe clamping blocks, and the stand columns are located on the inner sides of the first connecting grooves. The stand columns are connected to the support platform through the first connecting grooves,and three-way sleeve heads are installed on the upper part of the stand columns. Connecting heads are installed on the lower part of a cross bar, and the cross bar is connected to the vertical rods through the connecting heads. According to the protective device capable of being installed conveniently for the ascend operation vehicle, the clamping blocks are of a convex-shaped structure, and theclamping blocks are connected with the mounting grooves in a clamping mode; and the clamping blocks and the return springs form telescopic structures, so that the clamping blocks are pushed by the return springs to extend out of the mounting grooves to clamp and fix the vertical rods, and the stability of the vertical rod installation is improved.

The invention discloses a track spot lamp. The track spot lamp comprises a lamp body and a base, wherein the surface of the lamp body is rotatably connected with a fixing rack; the top of the fixing rack is rotatably connected with a bottom plate; a first latch is fixedly mounted on the top of the bottom plate; a through hole is formed in the first latch; the top end of the first latch penetratesthrough the base and extends into the base; and a flange is fixedly mounted on the top of the base. The invention relates to the technical field of LED lamps. According to the track spot lamp, a key cap is pressed to push an ejector rod to slide leftwards, the ejector rod pushes a connecting rod, thus, the left end of the connecting rod drives two second latches to be separated from each other towards two sides, the first latch is inserted in the base, then the key cap is released, under the elasticity effect of the spring, the ejector rod is pushed to the original position, the two second latches are inserted in the through hole in the first latch and are fixed, and the lamp body is fixed on the base. The track spot lamp is simple to operate, the lamp body can be easily disassembled, andtherefore, change and repair are facilitated.

The invention discloses a harmonic-free voltage transformer, which includes a working module, a main control unit and an operating device; the working module includes a voltage transformer and a resonance eliminator, and a conductive groove is provided at the central axis of the voltage transformer , a resonance eliminator is plugged inside the conduction tank, and one end of the resonance eliminator and the conduction tank are connected in series through current, so that the resonance eliminator and the voltage transformer are integrated; the main control unit includes a microprocessor device, memory, information collection module and timing module; the information collection module is respectively connected to the voltage transformer and the microprocessor, and the microprocessor is connected to the memory, the timing module and the operating device. The harmonic eliminator is detachably installed inside the conductive tank, which is convenient for replacement and maintenance, and effectively saves a lot of space; and effectively improves the intelligence of the system, facilitates the monitoring and maintenance of equipment, not only improves work efficiency, but also Enhanced security.
