Description

Technical Field

[0001] This utility model relates to the field of steel dam technology, specifically to a bottom-axis arc-surface steel dam body that is easy to install. Background Technology

[0002] A steel dam is a new type of adjustable overflow dam, mainly composed of civil engineering structures, steel gate bodies with fixed shafts, and opening and closing equipment. The gate body rotates around its bottom axis. This unique structure eliminates the need for bottom and side gate slots. Upstream water pressure rests on the circular shaft, ensuring a sealed state when the dam is erected or collapsed. The civil engineering components of the steel dam include the foundation slab and sidewalls, providing stable support. The steel gate body is typically made of high-quality steel and includes a panel, main beams, and secondary beams. The panel withstands water pressure, while the main and secondary beams provide support. The opening and closing equipment is generally hydraulically driven, using a motor to drive a bidirectional oil pump to control the dam's raising and lowering, achieving functions such as water storage, flood discharge, and overflow.

[0003] Most existing steel dams are fixed with ordinary bolts, which have poor anti-loosening and anti-fall-off functions. They are prone to loosening or even falling off under the conditions of water flow impact and vibration. The installation process is cumbersome and it is difficult to achieve a quick and firm connection between the bottom mounting plate, the side mounting plate and the dam waterway, which affects the overall structural stability and has poor sealing performance.

[0004] Based on this, a bottom-axis arc-surface steel dam body that is easy to install is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, the easily installed bottom-axis arc-shaped steel dam body includes a bottom mounting plate 1, two side mounting plates 2, and multiple anti-loosening bolts 3. The bottom mounting plate 1 is fixedly connected to the bottom of the dam body waterway by the anti-loosening bolts 3, and the two side mounting plates 2 are respectively fixedly connected to the two sides of the dam body waterway by the anti-loosening bolts 3.

[0028] A rotating shaft 4 is provided between the two side mounting plates 2. Multiple rotating parts 5 are equidistantly mounted on the outside of the rotating shaft 4. A first gate plate 6 and a second gate plate 7 are staggered on the top of the multiple rotating parts 5. Mounting grooves 8 are provided on both sides of the first gate plate 6. A sealing mechanism 9 is provided inside the mounting groove 8.

[0029] In this embodiment, the bottom mounting plate 1 and the two side mounting plates 2 are conveniently fixed to the dam waterway by the anti-loosening bolts 3. The anti-loosening bolts 3 have the functions of preventing loosening and preventing detachment, which improves the stability and strength of the installation of the bottom mounting plate 1 and the side mounting plates 2. The sealing mechanism 9 improves the sealing between the first gate plate 6 and the second gate plate 7, and at the same time improves the sealing between the first gate plate 6 and the side mounting plates 2.

[0030] In one embodiment, such as Figure 1 and Figure 3 As shown, the anti-loosening bolt 3 includes a bolt body 31. A fixing plate 32 is disposed inside the bolt body 31. A sliding rod 33 is slidably mounted through the top of the fixing plate 32. A conical block 34 is disposed at the bottom end of the sliding rod 33, and a top plate 35 is disposed at the top end of the sliding rod 33. A first spring 36 is sleeved on the outside of the sliding rod 33, located between the fixing plate 32 and the top plate 35. Four mounting holes 37 are equidistantly arranged in a ring on the outside of the bolt body 31. Insert pins 38 are slidably mounted inside the mounting holes 37. A semi-circular block 39 is disposed at one end of each insert pin 38. A second spring 310 is sleeved on the outside of the insert pin 38, located on one side of the semi-circular block 39. The top of the bolt body 31... The inner wall of the end is provided with a threaded groove 311. The top of the bolt body 31 is threadedly connected to the screw 312 through the threaded groove 311. The bolt body 31 is passed through the bottom mounting plate 1 or the side mounting plate 2. The bolt body 31 is rotated so that the bolt body 31 is threadedly connected to the bottom or side wall of the dam waterway. Then, the screw 312 is threadedly connected to the bolt body 31 through the threaded groove 311 using a tool. The screw 312 pushes the top plate 35 to move, so that the slide rod 33 drives the conical block 34 to move. The conical block 34 moves the four semi-circular blocks 39 outward. One end of the four mounting holes 37 is inserted into the concrete. The second spring 310 is compressed, so that the bolt body 31 has the function of preventing loosening and improving the stability of the installation.

[0031] In one embodiment, such as Figure 4 and Figure 5As shown, the sealing mechanism 9 includes multiple third springs 91, which are equidistantly arranged inside the mounting groove 8. An adjusting plate 92 is provided between one end of each of the multiple third springs 91. A sealing ring 93 is provided on one side of the adjusting plate 92. A first sealing groove 10 is provided on the opposite side of each of the two side mounting plates 2. A second sealing groove 11 is provided on both sides of the second gate plate 7. The first sealing groove 10 and the second sealing groove 11 are adapted to the sealing ring 93. The top of the bottom mounting plate 1 is provided with... During the rotation and closing of the sealing block 12, the first gate plate 6 and the second gate plate 7, due to the force, cause the sealing ring 93 to move the adjusting plate 92 into the mounting groove 8. The third spring 91 is compressed. When the first gate plate 6 and the second gate plate 7 are aligned, due to the reset action of the third spring 91, the adjusting plate 92 causes the sealing ring 93 to enter the second sealing groove 11 or the first sealing groove 10, thereby achieving a sealing effect. At the same time, the bottom of the first gate plate 6 and the second gate plate 7 are in contact with the sealing block 12, ensuring the sealing performance of the dam body.

[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, mounting bases 13 are fixedly installed on one side of both the first gate plate 6 and the second gate plate 7. A hydraulic cylinder 14 is rotatably mounted inside the mounting base 13 via a pin. A fixed base 15 is rotatably mounted on one end of the hydraulic cylinder 14 via a pin. The fixed base 15 is fixedly connected to the bottom of the dam waterway via anti-loosening bolts 3. When water needs to be released, the second gate plate 7 or the first gate plate 6 is rotated by the contraction of the hydraulic cylinder 14. At this time, water can flow out through the flipped second gate plate 7 or the first gate plate 6. When water does not need to be released, the hydraulic cylinder 14 extends, causing the second gate plate 7 or the first gate plate 6 to flip and close.

[0033] The above embodiments disclose a bottom-arc steel dam body that is easy to install. In this embodiment, the bolt body 31 is inserted through the bottom mounting plate 1 or the side mounting plate 2. The bolt body 31 is rotated so that it is threadedly connected to the bottom or side wall of the dam body waterway. Then, a tool is used to thread the screw 312 through the thread groove 311 to the bolt body 31. The screw 312 pushes the top plate 35 to move, so that the slide rod 33 drives the conical block 34 to move. The conical block 34 moves the four semicircular blocks 39 outward. One end of the four mounting holes 37 is inserted into the concrete. The second spring 310 is compressed, so that the bolt body 31 has an anti-loosening function and improves the stability of the installation.

[0034] When water needs to be released, the hydraulic cylinder 14 retracts to rotate the second gate 7 or the first gate 6, allowing water to flow out through the flipped second gate 7 or the first gate 6. When water release is not needed, the hydraulic cylinder 14 extends, causing the second gate 7 or the first gate 6 to flip and close. During the closing process, due to the force, the sealing ring 93 moves the adjusting plate 92 into the mounting groove 8, and the third spring 91 is compressed. When the first gate 6 and the second gate 7 are aligned, the third spring 91 resets, causing the adjusting plate 92 to move the sealing ring 93 into the second sealing groove 11 or the first sealing groove 10, thus achieving a sealing effect. At the same time, the bottoms of the first gate 6 and the second gate 7 fit against the sealing block 12, ensuring the sealing of the dam body.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
