[0019] The present utility model provides an aeration facility for a flood discharge tunnel, including a main body 101 and a portal-style aeration assembly. The portal-style aeration assembly includes a concrete bottom plate 102, side masonry walls 103, an air vent shaft 104, air vents 105, connecting rods 106, fixing plates 107, placement cavities 108, cleaning cylinders 109, connecting blocks 110, retractable rods 111, placement blocks 112, and handles 113. By the foregoing solution, problems existing in the existing aeration facilities, such as unstable aeration effect, uneven bubble distribution, and complex construction, which affect the aeration effect and service life, are solved. It can be understood that in the foregoing solution, during flood discharge, a stable aeration cavity formed by the air vent shaft 104 and the air vents 105 can achieve stable and uniform air replenishment, form a good air cushion layer. At the same time, the concrete bottom plate 102 and the side masonry walls 103 are in the shape of a portal, which has the advantages of optimizing the water flow pattern, reducing resistance, and improving the aeration efficiency. After the flood discharge is completed, in order to prevent the air vents 105 from being blocked by sediment in the flood, the staff will hold the handle 113 to take out the cleaning cylinder 109, and then adjust the length of the retractable rod 111 through the placement block 112 sliding on the retractable rod 111. Then, the staff stands on the fixing plate 107 and the connecting rod 106, holds the handle 113, and stabs the cleaning cylinder 109 into the air vents 105, thereby cleaning the blocked sediment. Thus, the problems existing in the existing aeration facilities, such as unstable aeration effect, uneven bubble distribution, and complex construction, which affect the aeration effect and service life, are solved, and the cleaning problem after the subsequent blockage of the air vents 105 is effectively guaranteed.
[0020] For this specific embodiment, the concrete bottom plate 102 is detachably connected to the main body 101 and is located below the interior of the main body 101. The side masonry walls 103 are fixedly connected to the concrete bottom plate 102 and are located on the upper side of the concrete bottom plate 102. Moreover, the side masonry walls 103 are arranged inside the main body 101. The air vent shaft 104 is fixedly connected to the main body 101 and is located above the interior of the main body 101. The air vents 105 are fixedly connected to the side masonry walls 103 and are located above the interior of the side masonry walls 103. Moreover, the air vents 105 are arranged below the air vent shaft 104. The concrete bottom plate 102 and the side masonry walls 103 are in the shape of a portal, and an air vent shaft 104 communicating with the outside atmosphere is arranged with the section center line as the axis, thereby optimizing the water flow pattern, reducing resistance, and improving the aeration efficiency. The air vent shaft 104 and the air vents 105 cooperate with each other to achieve stable and uniform air replenishment and form a good air cushion layer.
[0021] Among them, the connecting rod 106 is detachably connected to the main body 101 and is located inside the main body 101. Moreover, the connecting rod 106 is arranged above the inside of the ventilation shaft 104. The fixed disk 107 is detachably connected to the connecting rod 106 and is located at one end of the connecting rod 106 away from the main body 101. Also, the fixed disk 107 is arranged at the center of the inside of the ventilation shaft 104. The connecting rod 106 will cooperate with the fixed disk 107 to prevent the staff from falling into the ventilation shaft 104 when cleaning the sediment in the ventilation hole 105.
[0022] Secondly, the placement cavity 108 is fixedly connected to the main body 101 and is located inside the main body 101. In addition, the placement cavity 108 is arranged on one side of the ventilation shaft 104. The cleaning cylinder 109 is arranged inside the placement cavity 108. The placement cavity 108 is a place for placing the cleaning cylinder 109, and the cleaning cylinder 109 is mainly made of rubber and is the main functional component for cleaning the ventilation hole 105.
[0023] Meanwhile, the connecting block 110 is detachably connected to the cleaning cylinder 109 and is located above the cleaning cylinder 109. Also, the connecting block 110 is arranged inside the placement cavity 108. The retraction rod 111 is detachably connected to the connecting block 110 and is located above the connecting block 110. The connecting rod 106 is a structural component connecting the cleaning cylinder 109, and the retraction rod 111 is an auxiliary structural component that cooperates with the placement block 112 to extend, thereby cleaning the ventilation hole 105 more effectively.
[0024] In addition, the placement block 112 is slidably connected to the retraction rod 111 and is located on the outer surface above the retraction rod 111. The handle 113 is detachably connected to the placement block 112 and is located above the placement block 112. Also, the handle 113 is arranged above the main body 101.
[0025] When using the present utility model during flood discharge, a stable aeration cavity will be formed by the ventilation shaft 104 and the ventilation holes 105, achieving stable and uniform air supplementation, forming a good air cushion layer. At the same time, the concrete floor 102 and the side masonry wall 103 are in the shape of a portal, which has the advantages of optimizing the water flow pattern, reducing resistance, and improving ventilation efficiency. After the flood discharge is completed, in order to prevent the ventilation holes 105 from being blocked by sediment in the flood, the staff will hold the handle 113 to take out the cleaning cylinder 109, and then adjust the length of the retraction rod 111 by sliding the placement block 112 on the retraction rod 111. Then, the staff stands on the fixed disk 107 and the connecting rod 106, holds the handle 113, and stabs the cleaning cylinder 109 into the ventilation holes 105, thereby cleaning the blocked sediment. This will solve the problems existing in the existing aeration facilities, such as unstable ventilation effect, uneven bubble distribution, and complex construction, which affect the aeration effect and service life, and will also effectively ensure the cleaning problem after the subsequent blockage of the ventilation holes 105.
