Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a steel dam water-stopping device. Background Art

[0002] In water conservancy engineering buildings, water-stopping rubber is often used between the bottom shaft of the flip-type steel dam gate and the concrete foundation;

[0003] However, in the prior art, the bottom waterstop of a steel dam is usually provided with a concave notch at the bottom shaft flange and hinge seat. The gap between the concave notch and the bottom of the steel dam is prone to water leakage. During the rotation of the steel dam, the concave notch is prone to blockage by foreign objects such as stones, causing damage to the waterstop rubber and affecting the bottom waterstop effect of the steel dam. In addition, in order to reduce the resistance encountered by the steel dam during the rotation process, a certain gap is usually required 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 in the gap.

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

[0005] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Summary of the Invention

[0018] The upper scraper is fastened to the upper end of the bracket by a first locking bolt. The upper scraper is pressed against the upper part of the bottom shaft to close the accommodating groove.

[0019] Furthermore, the bottom water-stop assembly further includes:

[0020] The lower scraper is fastened obliquely to one end of the cushion layer through a second locking bolt. One end of the lower scraper is pressed against the lower part of the bottom shaft to cooperate with the upper scraper to close the accommodating groove.

[0021] Furthermore, one end of the cushion 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] There are two sets of arc-shaped baffles, which are respectively arranged on the outer side of the bottom shaft near both ends;

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

[0025] Furthermore, the bottom of the river channel is provided with an arc-shaped cavity for cooperating with the arc-shaped sleeve to accommodate the arc-shaped baffle;

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] See also Figure 1-8 , the present invention provides a technical solution:

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

[0047] The steel dam unit 1 is provided inside the river channel 100 and is used to block water from the river channel 100;

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

[0049] It should be noted that the bottom water stop assembly 22 directly transitions into the gap between the dam body 12 and the bottom of the river channel 100, so that the gap between the dam body 12 and the bottom of the river channel 100 is blocked. The entire blocking method does not require the use of the flange of the bottom shaft 11 and the concave notch on the upper part of the hinge seat to limit the bottom shaft 11, thereby preventing water leakage or obstruction by foreign objects such as stones at the flange of the bottom shaft 11 and the concave notch on the upper part of the hinge seat.

[0050] In addition, by transitioning the gap between the dam body 12 and the side wall of the river channel 100 through the side water-stopping assembly 21, water leakage in the gap between the dam body 12 and the side wall of the river channel 100 is avoided, thereby achieving comprehensive water-stopping of the dam body 12 and the river channel 100.

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

[0052] The bottom shaft 11 has two ends rotatably connected to the interior of the river channel 100;

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

[0054] The hydraulic cylinder 13 is provided with multiple groups for adjusting the angle of the dam body 12. The bottom of the river channel 100 is fixedly connected with a lower positioning card 131 for articulating and limiting the lower end of the hydraulic cylinder 13. One side of the dam body 12 is fixedly connected with an upper positioning card 121 for articulating and limiting the driving end of the hydraulic cylinder 13.

[0055] Further, such as Figure 3 As shown, the bottom water stop assembly 22 includes:

[0056] The cushion layer 221 is provided at the bottom of the river channel 100 and is used to raise the bottom of the river channel 100 on one side of the dam body 12. The cushion layer 221 is provided with a receiving groove 2212 for receiving the bottom shaft 11 at a corner on one side 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 a first locking bolt 223 . The upper scraper 224 is pressed against the upper portion of the bottom shaft 11 to close the receiving groove 2212 .

[0059] Furthermore, the bottom water-stop assembly 22 further includes:

[0060] The lower scraper 225 is fastened obliquely to one end of the cushion layer 221 by a second locking bolt 226 . One end of the lower scraper 225 is pressed against the lower portion of the bottom shaft 11 to cooperate with the upper scraper 224 to close the receiving groove 2212 .

[0061] One end of the cushion layer 221 is provided with an inclined surface 2211 for supporting the lower end of the lower scraper 225 , so as to support the lower scraper 225 in an inclined posture.

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

[0063] There are two sets of arc-shaped baffles 213, which are respectively arranged on the outer side of the bottom shaft 11 near both ends;

[0064] The arc sleeve 211 is fixedly connected to the inner wall of the river channel 100 and is used to accommodate the arc baffle 213. The arc sleeve 211 and the inner wall of the river channel 100 are sealed. The outer side of the arc baffle 213 contacts the arc sleeve 211 and the inner wall of the river channel 100, and is used to close 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 cooperating with 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, one end of the arc-shaped baffle 213 is fixedly connected to a locking rod 212;

[0068] The locking rod 212 is provided with a second locking hook 2121 on one side close to 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, Figure 5 , Figure 8 As shown, a second slot 2122 is provided on the side of the locking rod 212 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 locking slot 122 and the second locking slot 2122 for locking the locking rod 212 and the dam body 12 .

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

[0075] like Figure 3As shown, the present invention presses the upper portion of the bottom shaft 11 by the upper scraper 224 and presses the lower portion of the bottom shaft 11 by the lower scraper 225, so that the receiving groove 2212 between the bottom shaft 11 and the cushion layer 221 forms a closed area, thereby preventing stones and other debris at the bottom of the river channel 100 from entering the inner area of the receiving groove 2212 during the rotation adjustment of the bottom shaft 11, causing the bottom shaft 11 to be stuck during subsequent rotation adjustment;

[0076] like Figure 2-7 As shown, in addition, during the rotation adjustment process of the dam body 12, the arc-shaped baffle 213 is driven by the locking rod 212 to rotate along the arc-shaped sleeve 211. During the entire rotation adjustment process of the dam body 12, both sides of the dam body 12 are always closed by the cooperation of the arc-shaped sleeve 211 and the arc-shaped baffle 213, thereby preventing water in the river channel 100 from flowing out of 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 baffle 213 of the present invention, the arc baffle 213 is inserted into the arc sleeve 211, so that the locking rod 212 is clamped into 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 clamping groove 122 and the second clamping groove 2122 correspond to each other, and the clamping rod 214 is inserted into the first clamping groove 122 and the second clamping groove 2122 to complete the installation of the locking rod 212 and the dam body 12. The entire assembly and disassembly work is simple and quick, which facilitates the subsequent disassembly and maintenance of the arc baffle 213.

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