Pneumatic anti-freezing water gate based on geothermal waterless heating

Abstract

The invention discloses a pneumatic anti-freezing water gate based on geothermal waterless heating. The pneumatic anti-freezing water gate mainly comprises a gate body and a pneumatic anti-freezing device, wherein the gate body mainly comprises a gate pier, a gate platform and a gate plate; the gate platform is fixedly and transversely arranged at the upper-end opening position of the gate pier; two end parts of the gate platform are overlapped and fixed with the top of the gate pier; and the gate plate is positioned below the gate platform. According to the pneumatic anti-freezing water gatedisclosed by the invention, air is continuously injected through a fan into a vertical air injecting pipe; at the time, the air in the vertical air injecting pipe is sprayed from an air nozzle after entering an air diffusing device; water accumulated in gate plate sliding chutes can be disturbed through the sprayed airflow, thereby avoiding the circumstance of water accumulation; or when less water is accumulated in the gate plate sliding chutes, the evaporation rate of residual water can be effectively improved by continuously spraying air into the gate plate sliding chutes; and accordingly,the amount of the water accumulated in the gate plate sliding chutes can be reduced, the amount of the residual water can be reduced to a certain extent, and then the freezing strength can be reduced.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a pneumatic antifreeze water conservancy gate based on geothermal anhydrous heating. Background technique [0002] Gates are divided by crafting material. There are mainly wooden gates, wooden panel steel frame gates, cast iron gates, reinforced concrete gates and steel gates. According to the relative position of the gate top and the horizontal plane, there are mainly open-top gates and submersible gates. According to the nature of work, there are mainly working gates, emergency gates and maintenance gates. Divided according to the gate opening and closing method, there are mainly mechanically operated gates and hydraulic automatic gates controlled by the change of water pressure on the gate when the water level fluctuates. According to the different support forms of the door leaves, it is mainly divided into fixed wheel support gates, hinge support gates, slideway support gat...

AI Technical Summary

Problems solved by technology

[0003] In the common small valves at present, the gate is generally slidably installed in the chute of the gate pier. At this time, under the action of the gate hoist, the gate is driven to slide up and down along the chute of the gate pier, thereby opening and closing the gate. After closing, there is non-flowing water in the gate pier chute, so when the temperature is low, the non-flowing water is prone to freezing, which will cause the gate to freeze to death
