Abstract

The invention belongs to the technical field of substation equipment accessories, and is an adjustable substation equipment base adaptable to uneven settlement, which consists of three parts: a base, a support and a supporting plate. The foot seat is welded by three sleeves and the annular plate, and the three sleeves form 120° with each other. The support is composed of a screw and its nut. The top of the screw is smooth and spherical, and the bottom is all threads. The supporting plate is an annular plate, and the lower surface of the supporting plate has smooth spherical grooves. The smooth spherical top of the upper part of the screw can be placed in the smooth spherical groove, and connected with the supporting plate through an L-shaped connecting piece. When the substation equipment is tilted due to uneven settlement of buildings, the invention can be used to correct the substation equipment.

Description

An adjustable substation equipment base adapting to uneven settlement

technical field

The invention belongs to the technical field of substation equipment accessories, in particular to an adjustable substation equipment base adaptable to uneven settlement.

Background technique

As my country's development of coastal areas continues to increase, investment in coastal areas has also increased accordingly. At the same time, infrastructure construction in coastal areas has also gradually spread. In coastal areas, especially in coastal areas with marine deposits, due to the thicker soft soil layers, especially silty soil layers, generally more than 10m thick, this brings a lot of engineering geological problems to the corresponding infrastructure construction. question. For substation buildings and their ancillary facilities built on such foundation soil, it is necessary to do a good job in the treatment of soft soil foundation. When the building has uneven settlement, the substation equipment placed in the room will also tilt, which will affect the normal operation of the equipment.

Contents of the invention

The purpose of the present invention is to provide an adjustable substation equipment base adapting to uneven settlement, so as to solve the inclination problem of substation equipment caused by uneven settlement of buildings.

In order to solve the inclination problem of substation equipment caused by uneven settlement of buildings, the technical solution provided by the invention is: an adjustable substation equipment base adapting to uneven subsidence, including a base, a support and a supporting plate. Its special feature is: the design of the support system makes the screw rod always vertical to the ring plate of the foot seat during the adjustment process of the nut, so as to ensure the smooth rotation of the nut without damaging the thread. Through the principle of three points that are not collinear and form a plane, the screw ends are adjusted to the same horizontal plane, and the inclination of the substation equipment is corrected.

Detailed ways

The present invention is described below in conjunction with accompanying drawing.

The present invention is described below in conjunction with accompanying drawing. Referring to Figure 2, it is composed of a foot base 1, a support 2, and a support plate 3, the support 2 is placed on the foot base 1, the support plate 3 is placed on the support 2, and an L-shaped connector 8 and a small bolt 9 , 10 connect the above two. The foot seat 1 is connected by the sleeve 4 and the annular plate through welding, and the sleeve needs to have sufficient strength and corresponding length to meet the adjustment requirements of the screw rod. Support 2 is made up of nut 6 and screw rod 7, wherein the screw thread length of screw rod 7 should be as long as possible. Screw rod 7 top broken end is rounded, and drills small bolt hole in nearby position. The supporting plate 3 is an annular plate, and a spherical hole is left at the contact point with the support 2, and a small bolt hole is drilled at a nearby position. The connection between support 2 and supporting plate 3 is completed by connector 8 and small bolts 9,10. The small bolts do not need to be tightened, allowing some rotational flexibility in this area.

When in use, put the substation equipment on the adjustable base, and realize the level of the support plate by twisting the three nuts, so as to correct the inclination of the substation equipment.
