After long-term sun exposure and rain, the outer wall surface of the tank body will be damaged, mainly in the following aspects: first, in heavy rain, rainwater quickly accumulates, which will form a large impact force on the outer wall of the tank body, thereby causing damage to the paint surface of the tank body; second, due to the irregular and smooth curvature of the tank top, rainwater cannot be immediately drained, causing rainwater to continuously flow to the tank body, so that the tank body is in a state of rainwater immersion or dampness for a long time, thereby increasing the corrosion of the tank body; third, the accumulated sand, dust and other impurities on the tank top will flow to the reinforcing ring on the tank body and accumulate at the reinforcing ring, thereby increasing the corrosion of the tank body.
[0004] It can be understood that after the tank body is corroded by rainwater, sand and dust for a long time, the outer wall surface will be painted, rusted and even perforated, which requires a large amount of funds for corrosion and repair treatment, thereby increasing the maintenance cost; at the same time, during the maintenance process, the workers need to perform high-altitude operation, such as rust removal, paint brushing and repair welding on the tank body, which not only makes the construction difficult, but also has a high safety risk, which is easy to cause safety accidents; and even after the corrosion and repair treatment is completed, the tank body still has the phenomenon of paint peeling and rusting due to rainwater corrosion after a period of use, which cannot fundamentally solve the problem.
[0005] Therefore, it is necessary to design an economical and safe rainwater drainage device for the top of the oil tank, which can be modified without fire operation, prevent rainwater and impurities from accumulating on the tank top and flowing to the tank body, and effectively reduce the maintenance cost of the tank body.

[0030] Embodiment 1:
[0031] The utility model provides a vertical oil storage tank top rainwater centralized drainage device.
[0032] In an embodiment of the utility model, a vertical oil storage tank top rainwater centralized drainage device includes tank body 1 and sets up on the tank lid 2 of tank body 1 top surface, the tank lid 2 is gradually tapered from bottom to top setting, the top of tank body 1 is formed with annular flange 3 along its circumferential, is set with the water collecting groove 4 for collecting rainwater on annular flange 3, the bottom of water collecting groove 4 is set with several water outlet holes 5, several water outlet holes 5 all are provided with drain pipe 6 in;
[0033] Several drain pipes 6 far from the one end of water collecting groove 4 all are communicated with a annular water delivery pipe 7, and the annular water delivery pipe 7 is set up on the outer wall of tank body 1, and the annular water delivery pipe 7 is communicated with a water outlet pipe 8 extending to the bottom of tank body 1.
[0034] Specifically, as Figures 1 to 4 Indicated, the utility model discloses a vertical oil storage tank top rainwater centralized drainage device in the use process, when the weather is rainy day, rainwater directly falls on the top surface of tank lid 2, and because the tank lid 2 is gradually tapered from bottom to top setting, namely tank body 1 is conical, round table or half circle ball etc., and is set with water collecting groove 4 on the annular flange 3 of tank body 1 top, so that rainwater can flow into water collecting groove 4 along the top surface of tank lid 2, and the mud, dust and other impurities attached on the top surface of tank lid 2 are washed, and then the collection of rainwater and impurities can be completed, effectively prevent rainwater from carrying impurities to the outer wall of tank body 1, avoid the phenomenon such as paint drop, rust and perforation of the outer wall of tank body 1 due to the corrosion of rainwater and impurities, prolong the service life of tank body 1.
[0035] Further, because the bottom of water collecting groove 4 is set with several water outlet holes 5, and several water outlet holes 5 all are provided with drain pipe 6, when rainwater is contained in water collecting groove 4, rainwater can be automatically discharged outside water collecting groove 4 through several water outlet holes 5 and drain pipe 6, thereby effectively prevent rainwater from filling in water collecting groove 4, ensure the collection of rainwater and the protection effect of the outer wall of tank body 1, reliable in use, and simultaneously, through several water outlet holes 5 and drain pipe 6, the multi-point drainage of water collecting groove 4 can also be realized, thereby improve the drainage efficiency of water collecting groove 4, and the structure design is simple and reasonable.

Specifically, by providing a cover plate 11 at the opening of the water collection tank 4, workers can stand on the cover plate 11 to perform cleaning, unblocking, and other maintenance work on the water collection tank 4. Furthermore, since several through slots 12 are provided on the cover plate 11, rainwater on the tank lid 2 can flow through the through slots 12 into the water collection tank 4, thereby achieving rainwater collection. The structural design is simple and reasonable.
[0040] In one embodiment, a baffle 13 is also provided at the opening of the water collection tank 4, and the baffle 13 is located between the handrail 10 and the outer wall of the annular flange 3.
