Optionally, the number of the first mounting grooves 40 can be changed according to the size of the spherical tank 1000, for example, when the spherical tank 1000 is larger, the selected annular water-blocking adhesive tape 10 is longer, and the number of the corresponding first mounting grooves 40 can be larger, so that the corresponding magnets 30 can be conveniently arranged for prepositioning, and convenience is provided for filling the adhesive.
In addition, due to the magnet 30, when the annular water blocking adhesive tape 10 is installed, subsequent adhesive filling operation can be carried out without the help of a person, and labor cost is reduced. Furthermore, the magnets 30 are detachably connected, and after one annular water-blocking adhesive tape 10 is installed, the magnets 30 can also be applied to installation work of the annular water-blocking adhesive tape 10 of another spherical tank 1000, so that the cost is saved.

Other metals or corresponding alloys that are more active and stable than the spherical tank 1000 may be used as long as corrosion protection of the chemical battery is achieved without affecting the stability of the spherical tank 1000.
In detail, the second installation groove 50 of the present embodiment is further provided with a gravity sensor for measuring the mass of the active metal 70, and when the mass of the active metal 70 is lower than a preset value, the gravity sensor gives an alarm to the upper computer. The gravity sensor can remind the worker of timely replacing the new active metal 70, and the worker can know the corrosion condition of the active metal 70, so that the active metal 70 cannot be replaced too early and wasted, and the spherical tank 1000 cannot be damaged due to untimely replacement.
An embodiment of the present application provides an installation method of an anticorrosion device for installing the above-mentioned spherical tank manhole anticorrosion device 100 to the spherical tank 1000, the method comprising:
the annular water-blocking rubber strip 10 is preset at the bottom of the spherical tank 1000 by a magnet 30 and surrounds a manhole 1001;
filling a gap between the annular water-blocking adhesive tape 10 and the spherical tank 1000 with an adhesive, and fixing the annular water-blocking adhesive tape 10 and the spherical tank 1000;
the magnet 30 for pre-positioning is removed.
In the step of pre-positioning the annular water-blocking adhesive tape 10, the opening of the annular water-blocking adhesive tape 10 having the zigzag structure needs to be away from the spherical tank 1000, and in addition, the second mounting groove 50 needs to be upward.
Further, after the annular water-blocking adhesive tape 10 is fixed, an active metal 70 which is more active than the spherical tank 1000 is arranged in the second mounting groove 50 and a gravity sensor is arranged at the upward part of one side, close to the spherical tank 1000, of the annular water-blocking adhesive tape 10 to monitor the weight of the active metal 70, and the active metal 70 at the position can contact rainwater.

Because the opening of the annular water-blocking adhesive tape 10 with the concave-shaped structure faces away from the spherical tank 1000, rainwater can continue after flowing to the position of the annular water-blocking adhesive tape 10 because of no radian, and can not flow smoothly, and because the annular water-blocking adhesive tape 10 with the concave-shaped structure is divided into an upper cut-off part and a lower cut-off part in the longitudinal section direction, the rainwater can further directly fall down at the position and can not flow along the tank body, and the problem of poor corrosion prevention effect at the position of the manhole 1001 is effectively solved.
The active metal 70 is also arranged above the annular water-blocking adhesive tape 10 where a lot of rainwater is accumulated to form a chemical battery with the spherical tank 1000, so that the corrosion of rainwater to the tank body at the position is avoided. By monitoring the quality change of the active metal 70, the corrosion degree of the active metal 70 can be known, and when the critical value is reached, an alarm signal can be sent to a place on duty of a worker, so that the worker can timely know and replace the active metal 70, and the reliability of long-term anti-corrosion work of the spherical tank 1000 is guaranteed.
According to the installation method, the spherical tank can be installed on line, the spherical tank 1000 does not need to be stopped to be transformed like the installation method of live-fire welding, the transformation cost is greatly reduced, the labor intensity is reduced, and the installation efficiency is improved.
To sum up, spherical tank manhole corrosion prevention device 100 of this application can stop the rainwater through cyclic annular adhesive tape 10 cooperation binder and continue to flow to manhole 1001 department along spherical tank 1000 downstream, and it is also very convenient to cooperate magnet 30 to carry out corresponding installation to can install on line, when playing the problem of improving manhole 1001 by the rainwater corruption, can also save time and manpower, very practical.
