[0035] The present invention will be further described with reference to the following embodiments.

[0036] Example 1.

[0037] like Figure 1-6As shown, an oil level detection device for a transformer oil conservator includes an oil conservator body 1. A side end cover 2 is provided at one end of the oil conservator body 1. A detection guide column 3 is vertically mounted near one end of the oil conservator body 1 near the side end cover 2. A detection float ring 4 is movably sleeved on the detection guide column 3. A horizontal display mechanism 5 is fixedly mounted above the oil conservator body 1. A through hole 6 is formed in the top of the oil conservator body 1, which is connected to the horizontal display mechanism 5. The detection float ring 4 and the horizontal display mechanism 5 are connected by a force transmission rope 7, which movably passes through the through hole 6.

[0038] The present application is used for detecting the oil level in a transformer oil conservator. First, a detection guide column 3 is installed inside the oil conservator body 1. Then, a detection float ring 4 is raised and lowered inside the oil conservator body 1 by utilizing the buoyancy of the transformer oil. At the same time, the raising and lowering of the detection float ring 4 can drive a horizontal display mechanism 5 to display the displacement via a force transmission rope 7. The horizontal display mechanism 5 is placed on the top of the oil conservator body 1, eliminating the need for a partition inside the oil conservator body 1, thereby reducing costs.

[0039] The horizontal display mechanism 5 includes a double-tube housing 51, which is fixedly installed above the oil conservator body 1 and is connected to the through hole 6. A transmission cavity 52 and a display cavity 53 are provided inside the double-tube housing 51. An axial guide wheel 54 and a first radial guide wheel 55 are fixedly installed inside the transmission cavity 52, and a second radial guide wheel 56 is fixedly installed inside the display cavity 53. The transmission cavity 52 and the display cavity 53 are connected. An oil level display assembly 57 is fixedly installed inside the display cavity 53. The detection float 4 and the oil level display assembly 57 are connected by a force transmission rope 7, and the force transmission rope 7 is in rolling engagement with the axial guide wheel 54, the first radial guide wheel 55 and the second radial guide wheel 56.

[0040] The horizontal display mechanism 5 is fixedly mounted on the oil conservator body 1 via a double-tube housing 51. Meanwhile, the detection float 4 is connected to the oil level display assembly 57 via a force transmission rope 7 passing through a through hole 6, sequentially passing through an axial guide wheel 54, a first radial guide wheel 55, and a second radial guide wheel 56. The vertical lifting motion of the detection float 4 is converted into horizontal motion of the oil level display assembly 57, thereby displaying the oil level.

[0041] The oil level display assembly 57 includes a positioning tube 571, and a display block 572 is slidably installed inside the positioning tube 571. The end of the display block 572 close to the second radial guide wheel 56 is fixedly connected to the force transmission rope 7. A reset spring 573 is fixedly installed between the display block 572 and the end of the positioning tube 571 close to the second radial guide wheel 56, and the force transmission rope 7 moves through the positioning tube 571.

[0042] The oil level display assembly 57 drives the display block 572 to move horizontally inside the positioning tube 571 through the force transmission rope 7. At the same time, the installation of the reset spring 573 prevents the force transmission rope 7 from moving only to one side, resulting in inaccurate display of the oil level of the transformer oil conservator.

[0043] The axial guide wheel 54 is fixedly mounted in the center of the transmission cavity 52 , and the first radial guide wheel 55 and the second radial guide wheel 56 are mounted on the same end of the transmission cavity 52 and the display cavity 53 respectively.

[0044] The axial guide wheel 54 is located directly above the force transmission rope 7. At the same time, the force transmission rope 7 is also installed in the center of the oil storage tank body 1 through the detection floating ring 4. The first radial guide wheel 55 and the second radial guide wheel 56 convert the vertical force of the force transmission rope 7 into horizontal force, and transfer it from the transmission cavity 52 to the interior of the display cavity 53 to drive the oil level display assembly 57 to move.

[0045] A sliding block 8 is fixedly installed on the bottom of the detection guide column 3, and a card slot 9 is opened at one end of the bottom of the oil storage cabinet body 1 close to the side end cover 2, and the sliding block 8 and the card slot 9 are snap-fitted.

[0046] The cooperation between the sliding block 8 and the card slot 9 makes the installation of the detection guide column 3 more convenient, and its position can be fixed by the side end cover 2 of the transformer oil conservator.

[0047] A transparent display area 10 is provided on the double-tube housing 51 , and the positioning tube 571 corresponds to the transparent display area 10 . The positioning tube 571 is made of a transparent material.

[0048] The transparent display area 10 facilitates observation of the oil level from outside the transformer oil conservator. The position of the display block 572 of the positioning tube 571 can be observed from the transparent display area 10, thereby knowing the oil level.

[0049] The detection float ring 4 is equipped with a counterweight 11

[0050] The counterweight 11 can prevent the detection floating ring 4 from being suspended in the air due to the gravity being less than the elastic force of the return spring 573 .

[0051] The utility model is installed inside the oil conservator body 1 by clamping the detection guide column 3 and the sliding clamping block 8, which simplifies the steps of installing the oil level detection device of the transformer oil conservator. The horizontal display mechanism 5 on the top of the oil conservator is directly driven by the force transmission rope 7 for display, which has strong replaceability and convenient maintenance. In addition, there is no need to install a partition inside the oil conservator, which reduces the installation cost.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
