Description

Technical Field

[0001] This utility model relates to the field of air shield dam technology, and in particular to a novel double-airbag air shield dam anchoring structure. Background Technology

[0002] Air-shield dams, also known as pneumatic steel-shield rubber dams, are a new type of water-retaining structure that combines the advantages of rubber dams and steel gates, offering a balance of rigidity and flexibility. Their structure mainly consists of a shield plate, inflatable airbags, and a control system. Inflatable airbags support the shield plate to retain water; after the airbags are deflated, the dam collapses, with the airbags lying beneath the shield plate, preventing damage from river sand, ice, and other debris. The airbags are filled with gas, allowing for rapid collapse. All components are prefabricated, resulting in a short installation period. The modular design of the shield plate and airbags facilitates repair. Double-airbag air-shield dams use two airbags to support the shield plate, providing even greater stability.

[0003] Patent document CN210797463U discloses a double-airbag air-shield dam, comprising a concrete layer, a shield plate installed on the concrete layer, a lower airbag fixed to the upper surface of the concrete layer, and an upper airbag fixed to the lower airbag and abutting the lower arc-shaped surface of the shield plate. A connecting assembly for connecting the shield plate and the concrete layer is installed on the concrete layer, and a buffer assembly for cushioning is installed between the concrete layer and the lower arc-shaped surface of the shield plate. During flood discharge, workers only need to release the gas from the upper and lower airbags. At this time, the supporting force on the shield plate from the upper airbag gradually decreases, causing the shield plate to tilt towards the upper airbag. During this process, the buffer assembly plays a good cushioning role, preventing the shield plate from instantly tilting and bursting the upper and lower airbags due to the large flood pressure.

[0004] The aforementioned double-airbag air shield dam, which simply fixes the V-shaped rubber plate and the first plate to the concrete layer with anchors and fastening nuts, has poor air stability and is unstable in use. To address these issues, we have introduced a new type of double-airbag air shield dam anchoring structure. Utility Model Content

[0005] This utility model discloses a novel double-airbag air shield dam anchoring structure, which aims to solve the technical problem of poor air stability and unstable use in related technologies that simply fix the V-shaped rubber plate and the first plate to the concrete layer by anchor nails and fastening nuts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel double-airbag air-shield dam anchoring structure includes a concrete layer and a connecting plate. The concrete layer has pre-embedded grooves equidistantly spaced on one side of its top. Anchor nails are embedded in the pre-embedded grooves through concrete. The connecting plate has through grooves on the side near the anchor nails. The top of each pre-embedded groove passes through the through groove inside the connecting plate. Each anchor nail has a sliding groove inside. A sliding rod is slidably connected inside the sliding groove. A push block is fixedly installed at the bottom of the sliding rod. A first spring is sleeved on the outside of the push block. The top and bottom of the first spring are fixedly connected to the sliding groove and the push block, respectively. A locking block is symmetrically slidably connected to the bottom of the sliding groove. The connecting plate has locking grooves inside and near the locking blocks. The locking blocks extend into the locking grooves. An avoidance groove is formed at the top of the sliding groove. The top of the sliding rod extends through and into the avoidance groove, slidably connecting to the anchor nail. An outer nut is threaded onto the outer top of the anchor nail. A push column is fixedly installed on the side of the outer nut near the avoidance groove, extending into the avoidance groove.

[0008] By embedding anchors in the corresponding pre-embedded grooves through concrete, passing the through grooves inside the connecting plate through the corresponding anchors, and rotating the threads of the outer nut on the outside of the anchor tip, the push rod pushes the slide rod downwards, causing the push block to move down. The push block then pushes the locking blocks on both sides to move into the corresponding locking grooves and extend into the locking grooves. This strengthens the fixation between the connecting plate and the concrete layer, solving the technical problem of poor air stability and unstable use in related technologies that simply fix the V-shaped rubber plate and the first plate to the concrete layer with anchors and fastening nuts.

[0009] In a preferred embodiment, a fixing block is fixedly installed on one side of the top of the connecting plate, and a shield plate is connected to the outside of the fixing block via a rotating shaft. A buffer plate is fixedly installed on the side of the shield plate away from the concrete layer. The shield plate and the connecting plate are fixed together by a sealing element. A second airbag is fixedly installed on the side of the shield plate close to the concrete layer. A first airbag is fixedly installed on the top of the concrete layer close to the second airbag. The first and second airbags are fixedly connected. Positioning frames are fixedly installed at equal intervals on the side of the shield plate close to the concrete layer. Each positioning frame has a symmetrically threaded positioning bolt inside. An elastic support strip is connected between two corresponding positioning frames.

[0010] The dual airbag setup with No. 1 and No. 2 airbags provides more stable support for the shield plate. Furthermore, a device for inflating and deflating the No. 1 and No. 2 airbags should be installed in the middle of the concrete layer. The positioning frame, positioning bolts, and elastic support bars further enhance the support for the shield plate.

[0011] In a preferred embodiment, a support rod is fixedly installed on the side of the shield plate near the second airbag, a connecting block is fixedly installed on one side of the support rod, a first connecting groove is opened on the side of the support rod away from the connecting block, one of the connecting blocks extends into the other first connecting groove and is fixed by a fixing bolt, a slot is opened around the connecting block, and a locking block is fixedly installed inside the first connecting groove and near the slot.

[0012] By setting a connecting block on one side of one support rod to extend into the No. 1 connecting groove on the other side of the support rod and fixing it with a fixing bolt, as well as setting a locking block and a locking groove, it is convenient to quickly fix and install the two shield plates together.

[0013] In a preferred embodiment, a connecting rod is fixedly installed on the side of the shield plate near the first connecting groove, and a second connecting groove is opened on the side of the shield plate away from the connecting rod. A connecting arc plate is fixedly installed on the side of the seal near the connecting rod, and a connecting arc groove is opened on the side of the seal away from the connecting arc plate. Limiting blocks are symmetrically opened on both sides of the connecting rod, and limiting grooves are symmetrically opened on both sides inside the second connecting groove.

[0014] By extending the connecting rod on one side of one shield plate into the No. 2 connecting groove on the other side of the shield plate, and extending the connecting arc plate on one side of one seal into the connecting arc groove on the other side of the seal, the sealing performance at the connection between the two shield plates is enhanced. The limiting block and limiting groove facilitate the positioning of the connection between the connecting rod and the No. 2 connecting groove.

[0015] In a preferred embodiment, the anchor nail has symmetrically formed movable grooves inside and near the bottom of the sliding groove. The bottom of each snap-fit ​​block is fixedly installed with a movable plate. The movable plate extends into the movable groove and is slidably connected to the movable groove. The movable groove is fixedly installed with a fixed rod inside. A second spring is sleeved on the outside of each fixed rod. The two ends of the fixed rod are fixedly connected to the movable plate and the movable groove, respectively.

[0016] The movable groove, movable plate, fixed rod and No. 2 spring are designed to enhance the stability of the movement of the two locking blocks. When the connecting plate is disassembled, the locking block can be quickly moved into the sliding groove by the No. 2 spring when the push block moves upward, making disassembly more convenient.

[0017] In a preferred embodiment, sealing strips are symmetrically fixedly installed on the bottom of the connecting plate, and sealing grooves are provided on the side of the concrete layer near the sealing strips, with the sealing strips extending into the sealing grooves.

[0018] By setting a sealing strip at the bottom of the connecting plate to extend into the sealing groove inside the concrete layer, the sealing performance between the connecting plate and the concrete layer is enhanced.

[0019] In a preferred embodiment, a rotating ring is fixedly installed at the bottom of the outer nut, and a rotating groove is formed on the top of the connecting plate near the rotating ring.

[0020] By setting a rotating ring that extends into the rotating groove and is rotatably connected to the rotating groove, the operation becomes more stable.

[0021] The novel double-airbag air shield dam anchoring structure provided by this utility model has the following advantages:

[0022] Firstly, by pre-embedding anchors in the corresponding pre-embedded grooves through concrete, passing the through grooves inside the connecting plate through the corresponding anchors, and rotating the threads of the outer nut on the outside of the top of the anchor, the push rod pushes the slide rod downwards, causing the push block to move down, and the push block pushes the locking blocks on both sides to move into the corresponding locking grooves and extend into the locking grooves. This helps to strengthen the firmness of the connection between the connecting plate and the concrete layer, and solves the technical problem of poor air stability and unstable use in related technologies that simply fix the V-shaped rubber plate and the first plate to the concrete layer by anchors and fastening nuts.

The through groove inside the connecting plate 2 passes through the corresponding anchor nail 4. The outer nut 11 is screwed onto the outside of the top of the anchor nail 4. The push rod 12 pushes the slide rod 6 downward, causing the push block 7 to move downward. The push block 7 pushes the locking blocks 8 on both sides to move into the corresponding locking groove 9 and extend into the locking groove 9.

[0037] In the above technical solution, considering the sealing problem between the two shield plates 15, the specific operation is as follows to solve this problem:
