The invention relates to a cooling tower structure. The cooling tower structure comprises a cooling tower body. The cooling tower body is internally provided with a cooling draught fan, water distributors, padding and a water storage pond all of which are sequentially arranged from top to bottom. The side wall of the cooling tower body is provided with an air inlet and an air outlet. A filtering sieve is arranged above the water storage pond. The bottom wall of the water storage pond is of a V-shaped structure. A plurality of magnetic rods are arranged on the bottom wall of the water storage pond, the lower end portions of the magnetic rods are fixed to the bottom wall of the water storage pond, and magnetic balls are arranged on the upper end portions of the magnetic rods. The side wall of the water storage pond is provided with a water draining opening which communicates with a water draining pipeline, and the water draining pipeline is provided with an anti-blockage elastic ball bags. The cooling tower structure can effectively filter and adsorb metal fragments, the water draining opening is not blocked easily, and the cooling tower structure has the beneficial effects that the structure is simple and reasonable and a user can use the cooling tower structure conveniently and other beneficial effects.
