The technical scheme of the utility model is that: the anti-theft door comprises an upper door ring (1), a high-strength organic glass plate (2), a countersunk screw (3), a lower door ring (4), a handle (5), an oil tank top cover (6), a backing plate (7), a rubber pad (8), an oil retainer ring (9), a connecting rod (10), a rotating shaft (11) and a support (12). Go up door ring (1) and press fitting high strength organic glass board (2) on door ring (4) upper portion down together with backing plate (7) through countersunk screw (3), excircle one side and handle (5) welding of door ring (4) down, the excircle opposite side and the one end welding of connecting rod (10) of door ring (4) down, the other end and pivot (11) welding of connecting rod (10), the dress is worn in the mounting hole of support (12) in pivot (11), support (12) weld in oil tank top cap (6) upper surface, welding and the same oil retainer ring (9) of manhole internal diameter on oil tank top cap (6), rubber pad (8) are installed on oil retainer ring (9) upper portion.

Principle of operation

Will the utility model discloses the equipment is accomplished the back, need not open into under the people's door cover board condition, operating personnel can be in a certain position of people's side top, through high strength organic glass board (2) direct observation oil level and oil stream condition in the oil tank, satisfies the power station demand of patrolling and examining daily.

When the cover plate of the door for entering a person is required to be opened, the handle (5) welded on the lower door ring (4) is pulled up manually, so that the cover plate integrally rotates upwards for 180 degrees around the rotating shaft (11) on the support (12) through the connecting rod (10), the upper door ring (1) contacts the top cover (6) of the oil tank, and the cover plate of the door for entering a person is completely opened at the moment.

When the person entering door cover plate needs to be closed, the handle (5) welded on the lower door ring (4) is pulled up manually, so that the whole cover plate rotates reversely for 180 degrees around the rotating shaft (11) on the support (12) through the connecting rod (10), the lower door ring (4) is pressed on the rubber pad (8) on the upper part of the oil retainer ring (9), and the person entering door cover plate is closed.

Technical effects

When the oil return tank normally runs and is patrolled and examined in general power station, lean on opening into people's door apron at every turn and observe oil level and oil stream in the oil return tank, it is very inconvenient to operate, also does not benefit to and pollutes the protection to the oil yet.

The utility model discloses a set up the observation window on the door cover board of entering the people, can the inside oil level meter oil flow condition of direct observation oil return tank.

The utility model discloses a pivot and handle structure need whole translation type to advance people's access door cover board for the tradition, open and close convenient more laborsaving.

The utility model discloses the oil scraper ring and the rubber gasket that set up can prevent that oil return tank upper surface equipment oil impregnate from flowing into oil return tank inside through the manhole, can prevent again that outside dust from getting into oil return tank and polluting the inside oil body when the door cover board of entering the people closes.

Detailed Description

As shown in fig. 1 and 2, the cover plate of the manhole door of the oil return tank with the observation window is composed of an upper door ring 1, a high-strength organic glass plate 2, a sunk screw 3, a lower door ring 4, a handle 5, an oil tank top cover 6, a backing plate 7, a rubber pad 8, an oil retainer ring 9, a connecting rod 10, a rotating shaft 11 and a support 12.

Go up door ring 1 and pass through countersunk screw 3 with high strength organic glass board 2 together with backing plate 7 pressure equipment on 4 upper portions of lower door ring, the excircle one side and the welding of handle 5 of lower door ring 4, the excircle opposite side of lower door ring 4 and the one end welding of connecting rod 10, the other end and the pivot 11 welding of connecting rod 10, pivot 11 wears to adorn in the mounting hole of support 12 and can freely rotate, support 12 welds in oil tank top cap 6 upper surface, weld the same oil slinger 9 of manhole internal diameter on the oil tank top cap 6, rubber pad 8 is installed on oil slinger 9 upper portion, the shock attenuation is sealed when being used for with the contact of lower door ring 4.

After the equipment is accomplished, under the apron condition of closing, operating personnel can be in the certain position of people's side top of entering, through the interior oil level of high strength organic glass board 2 direct observation oil tank and the oil flow condition.

When the cover plate of the door for entering a person needs to be opened, the handle 5 welded on the lower door ring 4 is pulled upwards manually, so that the cover plate integrally rotates 180 degrees upwards around the rotating shaft 11 on the support 12 through the connecting rod 10, the upper door ring 1 contacts the top cover 6 of the oil tank, and the cover plate of the door for entering a person is completely opened at the moment.

When the cover plate of the entrance door needs to be closed, the handle 5 welded on the lower door ring 4 is pulled up manually, so that the whole cover plate rotates reversely for 180 degrees around the rotating shaft 11 on the support 12 through the connecting rod 10, and then the whole lower door ring 4 is pressed on the rubber pad 8 at the upper part of the oil retainer 9, and the closing of the cover plate of the entrance door is completed.

Finally, the scope of protection of the present invention is not limited to the embodiments described above. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention.
