Description

Technical Field

[0001] This utility model relates to the technical field of preventing ice and freezing disasters in rivers and reservoirs, and in particular to an air bubble anti-freezing device for water conservancy projects. Background Technology

[0002] Due to the influence of special climate and environment, freezing damage to reservoirs and rivers in cold regions occurs frequently and is severe. This freezing damage poses a significant threat to the security of natural resources and brings many adverse effects to the production and lives of local residents. Freezing damage can cause erosion and damage to the panels of flood control structures in rivers and reservoirs. If not prevented in time, it will directly affect the safe operation of the structures, shorten their service life, and increase the difficulty of maintenance and management. To address this situation, bubble anti-icing devices are typically used. These devices effectively prevent ice from forming on the water surface by creating a turbulent group of bubbles. The devices use gas for discharge, causing no environmental pollution and meeting environmental protection requirements.

[0003] Currently, the anti-freezing devices used in water conservancy projects generally employ pipes with air pores, which are relatively complex to lay. If the pipes are damaged, they need to be completely disassembled, which is time-consuming and labor-intensive. Utility Model Content

[0004] This utility model aims to address the shortcomings of existing technologies by providing a bubble anti-icing device for water conservancy projects.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A bubble anti-freezing device for water conservancy projects includes an upper connecting pipe, a plurality of bubble radiation devices are installed sequentially at the bottom of the upper connecting pipe, a gas conveying pipe is connected to the upper end of the upper connecting pipe, and a gas supply device is connected to the gas conveying pipe.

[0007] The bubble radiant device includes a central tube with connecting flanges at the top and bottom. Several radiant tubes are arranged circumferentially on the side wall of the central tube, and bubble screens are connected to the ends of the radiant tubes. The bottom of the central tube of the lowest bubble radiant device has a closed structure.

[0008] The lower end of the upper connecting pipe is provided with a bottom connecting flange, which is fixedly connected to the connecting flange of the corresponding bubble radiation device by bolts. The side wall of the upper connecting pipe is provided with a ring plate.

[0009] Several floats are installed around the circumference of the ring plate, and the ends of the floats are equipped with buoys.

[0010] The bottom flange of the lowest bubble radiant device is fixed with anchor bolts.

[0011] The lengths of the radiation tubes corresponding to the bubble radiation devices are arranged in ascending order from top to bottom.

[0012] The mesh diameter of the bubble grates corresponding to the bubble radiation devices is set to increase sequentially from top to bottom.

[0013] The beneficial effects of this utility model are: the bubble radiation device and the upper connecting pipe of this utility model are set separately, which can be installed as needed, making it highly adaptable, and can be maintained and replaced as needed, reducing replacement costs, and improving gas radiation distribution and anti-freezing effect.

[0019] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 2 As shown, a bubble anti-freezing device for water conservancy projects includes an upper connecting pipe 1, a gas conveying pipe 3 connected to the upper end of the upper connecting pipe 1, and a gas supply device 4 connected to the gas conveying pipe 3.

[0025] The gas supply device 4 can be a pressure-type gas supply device, such as an air pump, as long as it can pump gas.

[0026] Several bubble radiation devices 2 are installed sequentially at the bottom of the upper connecting pipe 1. The bubble radiation devices 2 can radiate gas in multiple directions in the water.

[0027] The bubble radiation device 2 includes a central tube 201. The top and bottom of the central tube 201 are provided with connecting flanges 202. Several radiation tubes 203 are arranged circumferentially on the side wall of the central tube 201. The ends of the radiation tubes 203 are connected to bubble mesh covers 204. The bottom of the central tube 201 at the bottom of the bubble radiation device 2 is a closed structure.

[0028] By sequentially increasing the length of the radiation tubes 203 corresponding to the bubble radiation devices 2 from top to bottom, the distribution range of the bubbles can be made wider.

[0029] The mesh diameter of the bubble shrouds 204 corresponding to the bubble radiation devices 2 from top to bottom is set to increase sequentially. The bubble shrouds 204 can divide the gas to form bubbles of different sizes, thereby achieving a better antifreeze effect.

[0030] The lower end of the upper connecting pipe 1 is provided with a bottom connecting flange 101, which is fixedly connected to the connecting flange 202 of the corresponding bubble radiation device 2 by bolts.

[0031] The entire device can be arranged in different ways, for example:

[0032] Floating installation can be adopted: A ring plate 102 is provided on the side wall of the upper connecting pipe 1, and several float plates 5 are installed around the circumference of the ring plate 102. The float plates 5 are provided with float balls 6 at their ends. Floating installation can be achieved by using the float plates 5 and float balls 6.

[0033] Alternatively, anchoring can be used: the bottom connecting flange 202 of the lowest bubble radiation device 2 is fixed with anchor 7 by bolts. The bottom of the anchor 7 has a conical structure, and anchoring can be achieved by using the anchor 7.

[0034] The bubble radiation device 2 and the upper connecting pipe 1 of this utility model are set separately, which can be installed as needed, making it highly adaptable. It can be maintained and replaced as needed, reducing replacement costs, and the gas radiation distribution is better, with better anti-freezing effect.

[0035] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
