Description

Underwater walking air blowing device for face rockfill dam in cold region

Technical Field

The utility model relates to a reservoir dam anti-icing technical field especially relates to a cold district's panel rock-fill dam is walking gas blowing device under water.

Background

The dam is an important component of the reservoir and plays an irreplaceable role in the aspects of irrigation, water regulation, flood control, power generation and the like. However, due to the influence of special climate and environment, the freezing damage of reservoir dams in cold regions is frequent and serious. The problem of freezing damage poses a significant threat to the safety of reservoir dams and brings many adverse effects to the lives of local residents. The ice damage can cause the reservoir dam slope protection panel to be denuded and damaged, and the panel joint water stop is damaged. The joint water stop of the water level change area of the concrete-filled rock-fill dam in the cold area is most easily damaged by freezing, an operation unit costs a large amount of money every year to repair the joint water stop of the surface of the concrete-filled rock-fill dam, and effective measures adopted at the present stage are mainly a method for treating the ice damage by combining early engineering deicing measures and later manual deicing measures. Manual de-icing is the main measure.

The engineering deicing measures are to protect the joint water seal on the surface of the face dam in the construction process, so that the joint water seal in a water level change area in winter is ensured not to be damaged by freezing, but the effect is poor, after a protective layer is usually damaged by freezing in winter, a local water seal joint can be seriously damaged, and then manual deicing measures are needed to be taken as conventional deicing measures to reduce the damage of the freezing damage to dam water seal wind to the maximum extent.

The manual deicing measure is the most effective method at present, and generally speaking, a plurality of people are orderly arranged in a straight line shape, and carry an ice-breaking tool respectively to stand on an ice cover layer to break the ice cover layer to break an ice crack so as to block the formation of an ice cover. However, in manual ice breaking operation, the engineering amount is huge, the required personnel are numerous, the capital investment is high, the personal safety cannot be effectively guaranteed, and the whole worker needs to do the work repeatedly in winter, so that the safety and economic influences are great.

In addition, the popularization of the anti-icing technology of the underwater bubble generating device effectively solves the problem, and the problems are met when the underwater bubble generating device is arranged on a pipeline; at present, various exquisite mechanical design structures and mature products exist in the pipeline collecting and releasing/accommodating device and are put into the market. Conventional pipeline winding and unwinding devices are mainly classified into three categories: the device comprises an automatic pipeline winding and unwinding device, an electric pipeline winding and unwinding device and a manual pipeline winding and unwinding device.

The three types of pipeline winding and unwinding devices have a common point in structural characteristics, namely the pipeline cladding winding type structure achieves the storage effect, the structure is safe, reliable, practical and convenient to operate, the working efficiency is greatly improved, the operation environment is also improved, and the service life of the pipeline is prolonged. Therefore, the utility model is widely used and popularized by the users.

However, the structural characteristics of the device also have certain use limitations, and once the use working condition is underwater, the device can expose the unstable and unsafe characteristics. The following are potential safety hazards which may be generated when the three common pipeline retracting devices are used for underwater operation.

1. Referring to fig. 1, the automatic pipeline winding and unwinding device stretches and retracts a pipeline by using a rewinding spring, a shell of the automatic pipeline winding and unwinding device is not waterproof, once the automatic pipeline winding and unwinding device works underwater for a long time, underwater unknown sundries and sludge enter the shell along a pipeline winding and unwinding channel, the rewinding spring is blocked, wound and filled, and the rewinding spring loses the functional characteristics, so that the pipeline winding and unwinding failure is caused.

2. Referring to fig. 2, the electric pipeline winding and unwinding device utilizes the motor to drive the winding drum to stretch and contract the pipeline, and firstly, during underwater operation, after long-time soaking and corrosion, the safety of the electric pipeline winding and unwinding device is difficult to ensure, and once a leakage point phenomenon occurs, the consequences are unreasonable. Secondly, once the underwater floating objects (such as branches and the like) are wound on the reel by the pipeline and cannot be found in time, the underwater floating objects tend to cause serious damage to the pipeline.

3. Referring to fig. 3, the manual pipeline storage device is similar to the electric pipeline storage device in working principle, and the pipeline is stretched and contracted by using the winding drum driven by manual operation, so that the structure is not suitable for underwater working condition operation.

Therefore, based on the above technical problems, those skilled in the art need to develop an underwater walking blowing device for concrete faced rockfill dams in cold regions.
