Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a steel dam water-stopping device. Background Technology

[0002] In hydraulic engineering structures, water-stop rubber is often used between the bottom shaft of the tilting steel dam gate and the concrete foundation.

[0003] However, in existing steel dam bottom waterstops, concave notches are usually provided at the bottom flange and hinge seat. Water leakage is prone to occur at the gap between the concave notch and the bottom of the steel dam. During the rotation of the steel dam, foreign objects such as stones can easily get stuck at the concave notch, causing damage to the waterstop rubber and affecting the waterstop effect at the bottom of the steel dam. In addition, in order to reduce the resistance encountered by the steel dam during rotation, a certain gap usually needs to be maintained between the two sides of the steel dam and the inner wall of the river channel. When the water pressure on the steel dam is high, water leakage occurs at this gap.

[0004] Therefore, it is necessary to propose a device that can comprehensively stop water from entering the bottom axis and both sides of the steel dam to solve the above problems.

[0005] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a steel dam water-stopping device to solve the problems of water leakage and stone blockage that easily occur in the gap between the two sides of the steel dam and the river channel, as well as the concave notch at the bottom flange and hinge seat of the steel dam, as mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0019] Furthermore, the bottom water-stopping component also includes:

[0020] The lower scraper is obliquely fastened to one end of the pad by the second locking bolt. One end of the lower scraper abuts against the lower part of the bottom shaft to cooperate with the upper scraper to close the receiving groove.

[0021] Furthermore, one end of the pad layer is provided with an inclined surface for supporting the lower end of the lower scraper, so as to support the lower scraper in an inclined posture.

[0022] Furthermore, the side water-stop assembly includes:

[0023] Two sets of arc-shaped baffles are provided, respectively located on the outer side of the bottom shaft near both ends;

[0024] An arc-shaped sleeve is fixedly connected to the inner wall of the river channel to accommodate the arc-shaped baffle, and the arc-shaped sleeve is sealed to the inner wall of the river channel.

[0025] Furthermore, the bottom of the river channel is provided with an arc-shaped cavity for accommodating the arc-shaped baffle in conjunction with the arc-shaped sleeve;

[0026] The curvature of the arc-shaped cavity is equal to the curvature of the inner wall of the arc-shaped sleeve.

[0027] Furthermore, a locking rod is fixedly connected to one end of the arc-shaped baffle;

[0028] The locking rod is provided with a second locking hook on the side near the arc-shaped baffle;

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-8 The present invention provides a technical solution:

[0046] A steel dam water-stopping device, comprising:

[0047] Steel dam unit 1 is located inside the river channel 100 and is used to impound water from the river channel 100;

[0048] The water-stopping unit 2 includes side water-stopping components 21 disposed on both sides of the steel dam unit 1 to stop the gap between the steel dam and the river channel 100, and bottom water-stopping components 22 disposed at the bottom of the steel dam unit 1 to stop the transition area between the bottom of the steel dam unit 1 and the river channel 100.

[0049] It should be noted that: by directly transitioning the bottom water-stop component 22 into the gap between the bottom of the dam body 12 and the bottom of the river channel 100, the gap between the bottom of the dam body 12 and the bottom of the river channel 100 is sealed. The entire sealing method does not require the use of the flange and the concave notch at the top of the hinge seat of the bottom shaft 11 to limit the bottom shaft 11, thus avoiding water leakage or obstruction by foreign objects such as stones at the flange and the concave notch at the top of the hinge seat of the bottom shaft 11.

[0050] In addition, by using the side water-stop component 21 to transition the gap between the dam body 12 and the side wall of the river channel 100, water leakage is prevented from occurring in the gap between the dam body 12 and the side wall of the river channel 100, thereby achieving complete water-stopping of the dam body 12 and the river channel 100.

[0051] As an improvement, such as Figure 1-2 As shown, the steel dam unit 1 includes:

[0052] The bottom shaft 11 is rotatably connected at both ends to the interior of the river channel 100;

[0053] The dam body 12 is fixedly connected to the outside of the bottom shaft 11 and is used to block water from the river channel 100.

[0054] The hydraulic cylinder 13 is provided in multiple sets for adjusting the angle of the dam body 12. The bottom of the river channel 100 is fixedly connected to a lower positioning card 131 for hinged limiting of the lower end of the hydraulic cylinder 13. The side of the dam body 12 is fixedly connected to an upper positioning card 121 for hinged limiting of the drive end of the hydraulic cylinder 13.

[0055] Furthermore, such as Figure 3 As shown, the bottom water-stopping component 22 includes:

[0056] The cushion layer 221 is provided with the bottom of the river channel 100 for raising the bottom of the river channel 100 located on one side of the dam body 12. The cushion layer 221 is provided with a receiving groove 2212 for accommodating the bottom shaft 11 at the corner of the bottom shaft 11.

[0057] The bracket 222 is fixedly connected to one side of the receiving groove 2212;

[0058] The upper scraper 224 is fastened to the upper end of the bracket 222 by the first locking bolt 223. The upper scraper 224 abuts against the upper part of the bottom shaft 11 and is used to close the receiving groove 2212.

[0059] Furthermore, the bottom water-stop component 22 also includes:

[0060] The lower scraper 225 is obliquely fastened to one end of the pad 221 by the second locking bolt 226. One end of the lower scraper 225 abuts against the lower part of the bottom shaft 11 and is used to cooperate with the upper scraper 224 to close the receiving groove 2212.

[0061] The pad 221 has an inclined surface 2211 at one end for supporting the lower end of the lower scraper 225, which supports the lower scraper 225 in an inclined position.

[0062] As an improvement, such as Figure 4-8 As shown, the side water-stopping assembly 21 includes:

[0063] Two sets of arc-shaped baffles 213 are provided, respectively located on the outer side of the bottom shaft 11 near both ends;

[0064] An arc-shaped sleeve 211 is fixedly connected to the inner wall of the river channel 100 to accommodate the arc-shaped baffle 213. The arc-shaped sleeve 211 is sealed to the inner wall of the river channel 100. The outer side of the arc-shaped baffle 213 contacts the arc-shaped sleeve 211 and the inner wall of the river channel 100 to seal the gap between the dam body 12 and the inner wall of the river channel 100.

[0065] Furthermore, the bottom of the river channel 100 is provided with an arc-shaped cavity 1001 for accommodating the arc-shaped sleeve 211 to accommodate the arc-shaped baffle 213;

[0066] The curvature of the arc-shaped cavity 1001 is equal to the curvature of the inner wall of the arc-shaped sleeve 211.

[0067] Furthermore, a locking rod 212 is fixedly connected to one end of the arc-shaped baffle 213;

[0068] The locking rod 212 is provided with a second locking hook 2121 on the side near the arc-shaped baffle 213;

[0069] The two ends of the dam body 12 are provided with first locking hooks 123 that cooperate with the second locking hooks 2121;

[0070] The locking rod 212 and the arc-shaped baffle 213 are both slidably connected to the outer side of the bottom shaft 11.

[0071] Among them, such as Figure 5 , Figure 8 As shown, the locking rod 212 is provided with a second slot 2122 on the side away from the arc-shaped baffle 213;

[0072] The two ends of the dam body 12 are provided with first slots 122 corresponding to the second slots 2122.

[0073] In addition, a locking rod 214 is inserted between the first slot 122 and the second slot 2122 to lock the locking rod 212 to the dam body 12.

[0074] It should be noted that: in the specific implementation process of this invention, such as Figure 7 As shown, when the dam body 12 is rotated, the hydraulic cylinder 13 is activated. The hydraulic cylinder 13 drives the dam body 12 to rotate through the upper positioning card 121. The dam body 12 drives the bottom shaft 11 to rotate relative to the river channel 100, thus completing the angle adjustment of the dam body 12.

[0075] like Figure 3As shown, the present invention uses an upper scraper 224 to press the upper part of the bottom shaft 11 against the bottom shaft 11 and a lower scraper 225 to press the lower part of the bottom shaft 11 against the bottom shaft 11, so that the receiving groove 2212 between the bottom shaft 11 and the pad layer 221 forms a closed area. This prevents stones and other debris from the bottom of the river channel 100 from entering the internal area of ​​the receiving groove 2212 during the rotation adjustment of the bottom shaft 11, which would cause the bottom shaft 11 to get stuck during subsequent rotation adjustment.

[0076] like Figure 2-7 As shown, in addition, during the rotation adjustment process, the dam body 12 also drives the arc-shaped baffle 213 to rotate along the arc-shaped sleeve 211 through the locking rod 212. Throughout the entire rotation adjustment process of the dam body 12, both sides of the dam body 12 are always sealed by the cooperation of the arc-shaped sleeve 211 and the arc-shaped baffle 213 to prevent water in the river channel 100 from flowing out from the gap between the dam body 12 and the inner wall of the river channel 100.

[0077] like Figure 5-6 , Figure 8 As shown, when installing the arc-shaped baffle 213, the arc-shaped baffle 213 is inserted into the arc-shaped sleeve 211, so that the locking rod 212 is engaged with the first locking hook 123 located at one end of the dam body 12 through the second locking hook 2121. At this time, the first slot 122 and the second slot 2122 correspond to each other. The locking rod 214 is inserted into the first slot 122 and the second slot 2122 to complete the installation of the locking rod 212 and the dam body 12. The entire installation and disassembly work is simple and quick, which facilitates the subsequent disassembly and maintenance of the arc-shaped baffle 213.

[0078] like Figure 3 As shown, the present invention fastens the upper scraper 224 to the bracket 222 with the first locking bolt 223 and the lower scraper 225 to the inclined surface 2211 with the second locking bolt 226. When it is necessary to disassemble and replace the upper scraper 224 or the lower scraper 225, the corresponding bolts can be removed, and the replacement process is convenient and quick.
