Water collection tank for rotary hydraulic cylinders

Abstract

A water collection tank for a rotary hydraulic cylinder includes a body and a cover. The body is made of plastic and has a reservoir, a first opening, a second opening, and a drain outlet. The first opening and the second opening are opposite to each other and communicate with the reservoir. The drain outlet is located at the bottom of the body and communicates with the reservoir. The cover is connected to the body and closes the periphery of the first opening. The cover has a third opening that communicates with the reservoir and is opposite to the second opening. The water collection tank, at least its body, is made of plastic, making it lightweight and convenient to use. Compared to traditional metal processing and corrosion prevention methods, it not only has a faster forming speed but also effectively reduces overall manufacturing costs.

Claims

1. A water collection tank for a rotary hydraulic cylinder, comprising: a body made of plastic, the body having a receiving groove, a first opening, a second opening, and a drain outlet, the first opening and the second opening being opposite to each other and communicating with the receiving groove, the drain outlet being located at the bottom of the body and communicating with the receiving groove; and a cover connected to the body and closing the periphery of the first opening, wherein... The cover has a third opening that communicates with the receiving groove and is opposite to the second opening.

2. The water collection tank as described in claim 1, wherein the cover is made of plastic.

3. The water collection tank as described in claim 1, wherein the cover system is detachably attached to the body.

4. The water collection tank as claimed in claim 3, wherein the body has a plurality of screw holes arranged along the periphery of the first opening; the cover has a plurality of through holes corresponding to the screw holes; and a plurality of fasteners pass through the through holes and are locked into the screw holes.

5. The water collection tank as claimed in claim 4, wherein the body has a plurality of protrusions formed on the tank wall of the tank, and each of the protrusions extends along the first opening toward the second opening; the screw holes are respectively formed on the protrusions.

6. The water collection tank as claimed in claim 3, wherein the body has a positioning groove formed along the periphery of the first opening; the cover has an inner side facing the receiving groove, and the inner side has a positioning flange that engages with the positioning groove.

7. The water collection tank as described in claim 1, wherein the diameter of the third opening is larger than the diameter of the second opening.
