Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion storage tanks, in particular to a storage tank manhole cover security device. Background Art

[0002] Anti-corrosion storage tanks are essential and important basic equipment in the petroleum, chemical, grain and oil, food, fire protection, transportation, metallurgy, national defense and other industries. Our economic life is always inseparable from large and small anti-corrosion storage tanks. The important role that anti-corrosion storage tanks play in the development of the national economy is irreplaceable.

[0003] The manhole of the storage tank is used for personnel to enter the tank to inspect or clean the inside of the tank. In normal use, the manhole mouth is covered with the end cover to seal the manhole. In order to achieve a better sealing effect, the manhole adopts a rigid structure and an anti-corrosion layer is coated on the inner surface. It is heavy. When it needs to be opened, several bolts are unscrewed and it needs to be caught and carried away manually. Due to its heavy weight, it is easy to fall and injure personnel. Utility Model Content

[0004] The utility model aims to provide a security device for a manhole cover of a storage tank. The manhole adopts a rigid structure and an anti-corrosion layer is coated on the inner surface. It is heavy. When it needs to be opened, several bolts are unscrewed and it needs to be caught and carried away manually. Due to its heavy weight, it is easy to fall and injure personnel.

[0005] To achieve the above-mentioned purpose, a tank manhole cover security device is provided, comprising: an end cover, a manhole is installed at the rear end of the end cover, the side wall of the manhole is rotatably connected to a connecting plate, the side wall of the connecting plate is fixedly connected to a connecting rod, the side wall of the end cover is fixedly connected to a connecting ring, a hook is installed on the outside of the connecting ring, one end of the hook passes through the middle of the connecting rod and extends to the outside, and a nut is threadedly connected to the outside of the hook.

[0006] According to the tank manhole cover security device, a plurality of bolts are arranged on the outside of the end cover, one end of each of the plurality of bolts passes through the middle of the manhole and extends to the outside, and two handles are fixedly connected to the outside of the end cover.

[0007] The above scheme has the beneficial effect: the utility model arranges a connecting rod, one end of which is detachably connected to the end cover. The end cover is opened and suspended by the connecting rod and rotated to the vicinity of the outer wall of the tank body next to the manhole. It does not need to be lifted manually and will not fall or injure people.

[0008] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
