Description

TECHNICAL FIELD

[0001] The utility model relates to a frame structure, more specifically, especially relates to a SVG power unit support frame structure. BACKGROUND

[0002] The SVG market presents a significant growth trend in the retention of high pressure, with the expansion of market size, the application requirement of high pressure SVG power frame structure is increasing day by day. However, the application of SVG power frame still has many problems to be solved: first, the installation efficiency of power unit fixed guide rail is low and the number of bolts used is more, specifically, the existing installation method needs to fix each guide rail on the cross brace in front and back using two screws first, then install the power unit on the guide rail, and fix the fixed screw of the corresponding power unit. This installation method is not only inefficient, but also needs a large number of bolts for fixing, which increases the installation cost and time cost.

[0003] Secondly, there is a lap problem between the optical fiber path and the copper bar of the power unit. In the process of arranging the control optical fiber to the unit optical fiber interface, due to improper path planning or insufficient installation accuracy, it is easy to cause the optical fiber to touch the unit connection copper bar. This not only may cause the damage of optical fiber, but also may cause the safety hazard of optical fiber lap copper bar discharge. In addition, the insufficient fixing strength of power unit on power frame is also a prominent problem. Due to the unreasonable fixing method or improper material selection, the fixing strength of unit on power frame cannot meet the expected requirement. This may cause the unit to loosen or even fall off during transportation, and then cause the damage of equipment or the occurrence of safety accident.

[0004] Finally, there is also the situation that the unit needs to be disassembled and transported again because of the insufficient fixing strength of unit on power frame. This not only increases the operation difficulty and cost, but also affects the overall performance and stability of the equipment. At the same time, if the fixing strength is not up to standard, it may also cause serious consequences such as frame cracking and damage during transportation. SUMMARY

[0011] The SVG power unit support frame structure of this utility model is made of SMC composite material for the king-shaped base, U-shaped vertical support, L-shaped reinforcing support, U-shaped horizontal support and L-shaped reinforcing front horizontal support. The L-shaped metal guide rail is made of one-piece metal sheet metal parts and has a powder coating layer on the outer surface of the L-shaped metal guide rail to avoid scratching the outer surface of the power unit.

[0012] The beneficial effects of this utility model are as follows: In the SVG power unit support frame structure of this utility model, the L-shaped metal guide rail for fixing the power unit is fixed on the U-shaped cross brace of the support frame. The rear end of the base plate of the L-shaped metal guide rail is provided with a lower pin and a countersunk hole, and the front end of the base plate is provided with a cylindrical pin. The U-shaped cross brace is provided with a rear bolt hole and a lower long sliding hole aligned with the countersunk hole and the cylindrical pin. When the L-shaped metal guide rail is fixed, the lower pin is engaged below the upper plate of the U-shaped cross brace, thereby limiting the upward and downward movement of the guide rail. The countersunk hole and the rear bolt hole are inserted with... Countersunk bolts limit the forward and backward movement of the guide rail, while cylindrical pins inserted into the lower oblong holes limit the left and right movement of the guide rail. Thus, the L-shaped metal guide rail is securely fixed to the U-shaped cross brace by a lower pin clip held under the upper plate of the U-shaped cross brace, a cylindrical pin inserted into the lower oblong sliding hole, and countersunk bolts screwed into the countersunk holes and rear bolt holes. Compared to existing guide rails that use at least two fixing bolts, this method ensures the guide rail's secure fixation while reducing the number of bolts required for installation, thus lowering costs and improving installation efficiency.

[0013] Furthermore, by designing the width of the L-shaped reinforcement front horizontal brace protruding beyond the U-shaped vertical brace to be greater than the width of the left and right connecting rows of the unit protruding beyond the U-shaped vertical brace, the optical fiber will not come into contact with the left and right connecting rows of the unit during the optical fiber deployment process, thus avoiding the occurrence of optical fiber damage and the occurrence of discharge through the optical fiber to the connecting copper busbar.

The fixing bolt passes through the unit bolt hole, the upper sliding hole, and the front bolt hole at the front end of the bottom of the power unit, giving the power unit high fixing strength on the L-shaped metal guide rail. This prevents the power unit from loosening or falling off during transportation and avoids damage to the power unit.

[0015] Furthermore, the U-shaped vertical brace, the king-shaped base, the L-shaped reinforcing brace, the U-shaped horizontal brace, and the L-shaped reinforcing front horizontal brace that constitute the support frame are all made of SMC composite material, which ensures that the formed support frame has good strength, meets the requirement of transportation without disassembling the power unit, and can avoid the occurrence of cracks or other damage to the support frame.
