SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a can reduce transformer oil and add the oil tank of frequency in order to practice thrift the combination formula photovoltaic power generation transformer of manpower.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a modular photovoltaic power generation transformer's oil tank which characterized in that: including the oil tank body, be provided with the oil storage tank on the oil tank body, the roof of oil tank body is provided with the oiling mouth in the oil storage tank below, the oil storage tank lower part is equipped with the oil-out, oiling mouth and oil-out pass through the conveyer pipe intercommunication, oil tank body roof is provided with the sealing ring in oiling mouth position, sealing ring upper end diameter is less than the lower extreme diameter so that the sealing ring is the toper, the oil tank still includes the body that can float on the oil level in the oil tank body, be connected with the connecting rod on the body, the connecting rod upper end is equipped with shape and sealing ring phase-match and can offset the sealing plug in order to seal the oiling mouth with.
Further, the connecting rod includes first branch and second branch, first branch is the straight-bar of vertical setting, the sealing plug sets up in first branch upper end, oil tank body bottom is provided with the guide post in oiling mouth below, be provided with on the guide post and supply first branch to stretch into wherein gliding guiding hole, second branch includes the vertical section parallel with first branch and the horizontal section that links to each other vertical section and first branch, the body sets up at vertical section lower extreme.
Further, the lower end of the oil storage tank is provided with support legs, and the support legs are fixed on the oil tank body through screws.
Compared with the prior art, the utility model has the advantages of it is following: this kind of liquid level in the transformer oil tank descends the back thereupon, the body can descend thereupon, because the connection of connecting rod, the sealing plug can descend simultaneously, sealing between sealing plug and the sealing ring is opened, transformer oil in the oil storage tank can get into in the oil storage tank, and when the liquid level in the oil storage tank risees gradually, the body, the connecting rod, the sealing plug all can rise thereupon, when the liquid level risees to a certain position, the sealing plug offsets with the sealing ring and seals the oiling mouth, when transformer oil in the oil storage tank is not enough like this, can supplement by the transformer oil in the oil storage tank, thereby reduce transformer oil's interpolation frequency, use manpower sparingly.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.
In the description of the present invention, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the terms of orientation and positional relationship indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the present invention.
Fig. 1 is a schematic structural diagram of a preferred embodiment of the present application, and as shown in the figure, the oil tank of the combined photovoltaic power generation transformer comprises an oil tank body 1, an oil storage tank 2 is arranged on the oil tank body 1, an oil filling port 11 is arranged on the top wall of the oil tank body 1 below the oil storage tank 2, an oil outlet 21 is arranged at the lower part of the oil storage tank 2, the oil filling port 11 is communicated with the oil outlet 21 through a delivery pipe 3, a sealing ring 12 is arranged on the top wall of the oil tank body 1 at the position of the oil filling port 11, the diameter of the upper end of the sealing ring 12 is smaller than that of the lower end thereof so as to lead the sealing ring 12 to be conical, the oil tank also comprises a floating body 13 which can float on the oil surface in the oil tank body 1, the floating body 13 is connected with a connecting rod 14, the upper end of the connecting rod 14 is provided with a sealing plug 15 which is matched with the sealing ring 12 in shape and can be abutted against the inner wall of the sealing ring 12 to seal the oil filling opening 11.
In this embodiment, the connecting rod 14 includes a first supporting rod 141 and a second supporting rod 142, the first supporting rod 141 is a vertically arranged straight rod, the sealing plug 15 is disposed at the upper end of the first supporting rod 141, a guiding column 16 is disposed at the bottom of the oil tank body 1 below the oil filling port 11, a guiding hole 17 for allowing the first supporting rod 141 to slide is disposed on the guiding column 16, the second supporting rod 142 includes a vertical section parallel to the first supporting rod 141 and a horizontal section connecting the vertical section and the first supporting rod 141, and the floating body 13 is disposed at the lower end of the vertical section. This prevents the connecting rod 14 from wobbling, which makes the sealing plug 15 more stably sealed with the sealing ring 12.
