Abstract

The embodiment of the utility model provides a maintenance manhole cover and a liquid tank, which relates to the technical field of fire-fighting equipment. The liquid tank includes the above-mentioned maintenance manhole cover, and the maintenance manhole cover includes a manhole cover body, the manhole cover body has a first side and a second side opposite to each other, the first side is used to cover the liquid tank, and the second side is provided with an overflow device and a liquid injection pipe. The liquid injection pipe is provided with a liquid injection hole extending along its own axial direction, and the maintenance manhole cover is also provided with a water injection joint, which is detachably connected to the liquid injection pipe to seal or open the liquid injection hole, and the water injection joint is used to connect with an external water pipe. The overflow device and the liquid injection pipe are both arranged on the manhole cover body. Therefore, during installation, the overflow device and the liquid injection pipe can be arranged on the manhole cover body in advance, and then the manhole cover body can be installed on the liquid tank, without having to install the overflow device and the liquid injection pipe on the top of the liquid tank respectively, which reduces the difficulty of installing the overflow device and the liquid injection pipe on the liquid tank.
