Embodiment Construction

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] See Figure 1-8 , A kind of antifreeze gate with:

[0030] Dam body, the back of the dam body is equipped with a telescopic cylinder that drives the dam body to turn over;

[0031] The bottom shaft is set at the bottom of the dam, and the bottom shaft is a hollow structure with through holes inside;

[0032] The sleeve core is installed in the through hole of the bottom shaft. The sleeve core is a hollow structure with a sleeve core central hole inside; a circumferentially extending guide groove is provided on the outer periphery of the sleeve core, and the guide groove communicates with the sleeve core central hole;

[0033] The rotating sleeve is rotatably installed on the sleeve core. The outer circumference of the rotating sleeve is provi...

Abstract

The invention discloses an anti-freezing gate. The anti-freezing gate comprises a dam body, a bottom shaft, a sleeve core, a rotary sleeve, an air inlet pipe and an air outlet. A telescopic cylinder for driving the dam body to overturn is arranged on the back side of the dam body. The bottom shaft is arranged at the bottom of the dam body. The bottom shaft is of a hollow structure with a through hole inside. The sleeve core is installed in the through hole of the bottom shaft. The sleeve core is of a hollow structure with a sleeve core center hole inside. A guide groove is arranged on periphery of the sleeve core and extends in the circumferential direction of the sleeve core. The guide groove communicates with the sleeve core center hole. The rotary sleeve is rotationally installed on thesleeve core. An air inlet hole communicating with the rotary sleeve center hole is formed in the periphery of the rotary sleeve. In the relative rotation process of the sleeve core and the rotary sleeve, the air inlet hole communicates with the guide groove all the time. The air inlet pipe penetrates through the bottom shaft and is connected with the air inlet hole of the rotary sleeve. The air outlet is formed in the periphery of the bottom shaft and communicates with the through hole of the bottom shaft. The anti-freezing gate can inhibit icing of a water surface in cold weather, and enables the dam body to be capable of overturning.

Description

Technical field [0001] The invention belongs to the technical field of hydraulic dams, and particularly relates to an antifreeze gate. Background technique [0002] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: during the use of the hydraulic dam, when encountering cold weather, the water surface freezes, causing the dam body to be unable to turn over and thus unable to open or close the dam body. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an antifreeze gate which can inhibit the freezing of the water surface in cold weather and enable the dam body to be turned over. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an antifreeze gate having: [0005] Dam body, the back of the dam body is provided with a telescopic cylinder that drives the dam body to turn over; [0...
