Description

Technical Field

[0001] The utility model relates to the technical field of power plant cooling circulating water, and specifically to an umbrella-shaped cooling tower. Background Art

[0002] As an important part of the power plant cooling circulation system, the cooling tower mainly conducts evaporation heat dissipation on the cooling water. Since the cooling tower is set outdoors, in summer, due to strong sunlight, the temperature of the circulating water is high, which affects the cooling effect of the cooling tower. In winter, due to the low temperature of the circulating water in the cooling tower, ice hanging is serious under the influence of cold wind. Ice hanging is likely to cause damage to the structure of the cooling tower, and the falling ice will also cause blockage at the inlet of the circulating water pump, further leading to cavitation damage of the circulating water pump, and even causing the circulating water to lose the unit and shut down. In view of this, an umbrella-shaped cooling tower is proposed. Summary of the Invention

It should be understood that these embodiments are used to illustrate the present utility model rather than limit the scope of the present utility model. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0018] In a specific embodiment, an umbrella-type cooling tower is provided, including the tower body a of the cooling water tower. In order to wrap and shield the tower body, shielding umbrellas are provided on both the north and south sides of the tower body a of the cooling water tower.

[0019] On this basis, in order to be able to fold and unfold the shielding umbrella according to the actual use situation, the shielding umbrella mainly includes an umbrella framework 4, which includes several rods. One end of each rod is hinged and installed on the outer side of the waist of the tower body a of the cooling water tower. A common umbrella surface 1 is installed on each rod. Similar to the existing umbrella structure, the umbrella framework 4 structure is constructed by dry rods, and one umbrella surface is fixed by multiple rods. In order to realize the opening and closing of the umbrella body, an unwinding motor 6 installed on the tower body a of the cooling water tower is also included. The output end of the unwinding motor 6 is wound with a towing rope 3, and the towing rope 3 is connected to the umbrella framework 4 and can pull the rods to swing. Therefore, in this example, the unwinding motor 6 winds the towing rope 3 to make the rods swing upward and fold.

[0020] On this basis, in order to realize the fixation of the folded umbrella body, a folding and fixing device 2 is also included. It is fixedly installed on the outer side of the waist of the tower body a of the cooling water tower. When the umbrella framework 4 rotates upward to the specified position, it can be connected to the folding and fixing device 2, and the tower body a of the cooling water tower can be wrapped by the shielding umbrellas on both sides. In order to realize the fixation of the umbrella framework 4 and the folding and fixing device 2, the folding and fixing device 2 of the present application includes several mounting frame plates 2.2. Every two mounting frame plates 2.2 are fixed in a group on the side wall of the tower body a of the cooling water tower, and a placement groove 2.4 is formed between the two mounting frame plates 2.2. Electromagnets 2.1 are installed on the outer sides of the two mounting frame plates 2.2, and bolts 2.3 are arranged on the inner sides of the two mounting frame plates 2.2. The electromagnet 2.1 can adsorb the bolt 2.3 to move outward to the outside of the placement groove 2.4, and the bolt 2.3 can move inward to the inside of the placement groove 2.4 through a spring. After the shielding umbrella is folded, the rods of the umbrella framework 4 can be placed in the placement groove 2.4, and jacks are provided on the rods. The bolt 2.3 can be inserted into the jacks to realize the fixation of the rods.

[0021] On this basis, to fix the umbrella body after it is deployed, several fixing piles 5 are further included, which are respectively arranged on the north and south sides of the cooling tower.

There is only one type of fixing pile on the north side, with a height of 20 centimeters above the ground, which can fix the umbrella bones.

[0022] For the specific usage method, during normal operation, the umbrella surface is folded and attached to the outer wall of the cooling tower. When the sunlight is strong and the circulating water temperature is too high, lower the south side umbrella surface, fix the umbrella bones to the south side fixing piles, and block the top of the cooling tower pool to avoid sunlight irradiation and reduce the circulating water temperature. When the sunlight is not strong, untie the fixing of the fixing piles and fold up the south side umbrella surface. When it is cold and windy in the north during the day in winter, lower the north side umbrella surface, fix the umbrella bones to the north side fixing piles 5, and can be fixed through the towing rope to block the north wind, while reducing the heat dissipation of the cooling water and increasing the circulating water temperature to avoid icing on the cooling tower. At night, also lower the south side umbrella surface, fix the umbrella bones to the south side low fixing piles to block the wind and increase the circulating water temperature. After the transformation, the problems of poor cooling effect and icing of the cooling tower can be solved, the safety of the unit is enhanced, the economy is enhanced, the reliability of the equipment is improved, and economic benefits are increased for the enterprise.

[0023] In order to further improve the shielding effect of the umbrella surface in this application, the umbrella surface 1 of the shielding umbrella on the south side of the cooling tower body a is made of fiberglass high-temperature resistant cloth and painted white to enhance the reflective effect. The umbrella surface 1 of the shielding umbrella on the north side of the cooling tower body a is made of PVC transparent rainproof cloth and painted black to enhance the heat absorption and heat preservation effect.
