Problems solved by technology

[0004] However, Chinese patent CN201520908963.1 does not consider external factors such as solar radiation in the area where the pouring warehouse surface is located, the ambient temperature outside the warehouse surface, and the water temperature of the spraying water. The wind speed of the machine fan is not precise enough to control!

Embodiment Construction

[0040] The structure and features of the present invention will be described in detail below in conjunction with the drawings and embodiments. It should be noted that various modifications can be made to the embodiments disclosed herein, therefore, the embodiments disclosed in the specification should not be regarded as limitations on the present invention, but only as examples of embodiments, and its purpose is to make the present invention The features of the invention are self-evident.

[0041] In order to monitor the atomization effect, study the relationship between spray volume and temperature drop, and study the relationship between spray and rainfall in the small environment, the applicant conducted spray-related experiments from April 2017 to September 2017. The test site is the Daxing test base of the China Academy of Water Resources and Hydropower Research, which is located near Banbidian Forest Park, Daxing District, Beijing.

Abstract

The invention provides a method for controlling a spray machine used for cooling the concrete bin surface. The method comprises the steps that according to whether the height distance between the spray machine and the concrete bin surface is more than 4.5 m or not, the angle of downward swinging of the spray machine is adjusted; and the spray amount and the fan air speed of the spray machine are controlled according to the actually-measured water temperature of spray water, external environment temperature of the concrete bin surface, and solar radiation of an area where the poured bin surfaceis located. The method has the remarkable effects on spray cooling optimization of the concrete bin surface and crack prevention of the concrete bin surface.

Description

technical field [0001] The invention relates to a method for controlling a sprayer, in particular to a method for controlling the spray volume, the wind speed of a fan and the up and down swing angle of a sprayer for cooling the surface of a concrete storehouse. The invention belongs to the technical field of water conservancy and hydropower engineering. Background technique [0002] In water conservancy and hydropower projects, some dams are made of concrete. How to ensure that there are no cracks on the surface of the concrete silo after pouring is very important! Controlling the pouring temperature is one of the important measures for concrete temperature control and anti-cracking, and controlling the ambient temperature of the concrete warehouse surface is an important means of controlling the pouring temperature. [0003] In order to control the ambient temperature of the concrete warehouse surface, usually, several sprayers are installed near the concrete warehouse su...
