Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower, and in particular to an anti-seepage and water-stopping structure for water conservancy and hydropower projects. Background Art

[0002] A dam refers to a weir or dike that blocks water from a river, such as a reservoir or river. A typical reservoir dam consists of a main dam, auxiliary dam, gravity dam, normal spillway, emergency spillway, newly added emergency spillway, Lingzheng Canal culvert, and power station. Dams can be categorized as concrete dams and earth-rockfill dams. The type of dam is selected based on a comprehensive consideration of the site's natural conditions, construction materials, construction site, diversion, construction schedule, and cost.

[0003] According to Chinese patent CN221320833U, an anti-seepage and water-stopping structure for use in water conservancy and hydropower projects is proposed. The device uses the cooperation of a buffer spring and a buffer plate to buffer and reduce the pressure of water waves. At the same time, the damper can increase the stability of the buffer plate. The cooperation of the pressure reducing hole and the pressure reducing groove can further reduce the pressure of water waves. The waterproof effect of the waterproof dam body is increased by the anti-seepage layer, the waterproof effect of the top of the device is increased by the waterproof layer, the water retaining plate can be used to block the water waves, and the strength of the waterproof dam body can be increased by strengthening the steel bars, thereby further improving the waterproof function of the dam.

[0004] However, there are still some shortcomings in this device. Although the device can buffer and relieve the pressure of water waves through the cooperation between the buffer spring and the buffer plate, when the water waves are scouring, it is easy for some water waves to seep out from the top of the buffer plate due to the inability to adjust the blocking height of the buffer plate to the water waves, and then scour the dam, affecting the anti-seepage and water-stopping effect of the dam. For this reason, we propose an anti-seepage and water-stopping structure for water conservancy and hydropower projects. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-seepage and water-stopping structure for water conservancy and hydropower projects, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-seepage and water-stopping structure for water conservancy and hydropower projects, comprising a base plate, a waterproof dam body fixedly connected to the center top of the base plate, and an anti-seepage component arranged on the side of the waterproof dam body, the anti-seepage component comprising a fixing frame fixedly connected to the outer wall of the waterproof dam body, a forward and reverse motor fixedly connected to the inner wall of the other end of the fixing frame, an output end of the forward and reverse motor fixedly connected to an output shaft, a driving gear fixedly connected to the middle outer wall of the output shaft, and a side wall of the driving gear. A half-toothed ring is meshed, and the inner wall of the side of the half-toothed ring is slidably connected to a limit ring. The bottom side wall of the limit ring is fixedly connected to a connecting block, and the other end of the connecting block is fixedly connected to a cross plate. The other end of the cross plate is fixedly connected to the outer wall of the base plate. The inner wall of the half-toothed ring is fixedly connected to an arc-shaped protective plate, and the inner wall of the arc-shaped protective plate is fixedly connected to a pressure-resistant cross block. By setting an anti-seepage component, the protection height of the arc-shaped protective plate against water waves can be adjusted to avoid higher water waves from eroding the waterproof dam body, thereby achieving a protective effect on the waterproof dam body.

[0007] The outer wall of the driving wheel is connected to the outer wall of the driving wheel through a belt transmission, and the driven wheel is located above the driving wheel, and the inner wall of the driven wheel is fixedly connected to a rotating rod, and the outer wall of one end of the rotating rod is rotatably connected to an L-shaped vertical plate through a bearing, and the other end of the L-shaped vertical plate is fixedly connected to the top of the waterproof dam body. The outer wall of the other end of the rotating rod is fixedly connected to the first bevel gear, and the bottom of the first bevel gear is meshed with a second bevel gear, and the inner wall of the second bevel gear is fixedly connected to the transmission shaft, and the bottom of the transmission shaft is fixedly connected to a screw, and the bottom outer wall of the screw is rotatably connected to the top of the base plate through a bearing, and the outer wall of the screw is threadedly connected to a socket block, and the side wall of the socket block is fixedly connected to the displacement plate, The other side is fixedly connected with a limit block, and the inner wall of the limit block is slidably connected to the limit column, and the bottom of the limit column is fixedly connected to the top of the base plate. When the output shaft rotates forward, it drives the driving wheel to rotate. During the rotation of the driving wheel, it drives the driven wheel to rotate through the belt transmission, and the driven wheel prompts the rotating rod to rotate. After the rotating rod rotates, it drives the second bevel gear to rotate through the first bevel gear. After the second bevel gear rotates, it drives the screw to rotate through the transmission shaft. Due to the limiting action of the limit column and the limit block on the displacement plate and the socket block, the socket block will be prompted to move downward along the outer wall of the screw, and drive the displacement plate to move downward, so that the bottom of the displacement plate contacts the top of the base plate, and the water flow is blocked by the displacement plate to prevent the water flow from penetrating the bottom of the waterproof dam body.

[0008] Preferably, an auxiliary component is also provided above the base plate, and the auxiliary component includes a counterweight block fixedly connected to the left top, and the counterweight block is located on the side of the waterproof dam body. The left top of the waterproof dam body is fixedly connected to a first support column, and the side wall of the first support column is fixedly connected to a protective rod, and the other end of the protective rod is fixedly connected to a second support column, and the bottom of the second support column is fixedly connected to the top of the waterproof dam body.

[0011] Preferably, there are several compression-resistant transverse blocks, and the several compression-resistant transverse blocks are distributed in a circular array along the central axis of the arc-shaped protective plate.

[0012] Preferably, the surface of the waterproof dam body is coated with a waterproof layer.

[0013] The present invention provides an anti-seepage and water-stopping structure for water conservancy and hydropower projects. The anti-seepage and water-stopping structure for water conservancy and hydropower projects has the following beneficial effects: (1) The anti-seepage and water-stopping structure for water conservancy and hydropower projects is provided with an anti-seepage component. In the process of anti-seepage and water-stopping of the waterproof dam body, it is necessary to block the water waves by means of an arc-shaped protective plate and a pressure-resistant cross block, so as to prevent higher water waves from scouring the waterproof dam body and causing erosion of the waterproof dam body. In order to block higher water waves, it is necessary to adjust the protective height of the arc-shaped protective plate against water waves. At this time, the operator turns on the forward and reverse motors. When the forward and reverse motors rotate forward, the output shaft is prompted to rotate forward. During the rotation of the output shaft, the driving gear is driven to rotate. The driving gear is engaged with the half-tooth ring.

During the rotation of the half-tooth ring, the arc-shaped protective plate is driven to tilt, so as to increase the protective height of the arc-shaped protective plate, thereby blocking higher water waves and preventing the waterproof dam body from being eroded. (2) The anti-seepage and water-stopping structure for water conservancy and hydropower projects can evenly balance the weight of the waterproof dam body by setting auxiliary components and counterweight blocks, thereby improving the stability of the waterproof dam body. By setting the first support column, the protective rod and the second support column, the mutual cooperation between the first support column, the protective rod and the second support column can be utilized, thereby increasing the safety of the waterproof dam body.

By setting up the anti-seepage component 31, in the process of anti-seepage and water-stopping the waterproof dam body 4, it is necessary to block the water waves through the arc-shaped protective plate 319 and the pressure-resistant cross block 3110 to prevent high water waves from scouring the waterproof dam body 4 and causing erosion to the waterproof dam body 4. In order to block high water waves, it is necessary to adjust the protection height of the arc-shaped protective plate 319 against the water waves. At this time, the operator turns on the forward and reverse motor 312. When the forward and reverse motor 312 rotates forward, it will prompt the output shaft 313 to rotate forward. During the rotation of the gear 13, the driving gear 314 is driven to rotate, and the driving gear 314 is meshed with the half-toothed ring 315. The half-toothed ring 315 is limited by the limiting ring 316 and the connecting block 317, which causes the half-toothed ring 315 to rotate along the outer wall of the limiting ring 316. During the rotation of the half-toothed ring 315, the arc-shaped protective plate 319 is driven to tilt, causing the protective height of the arc-shaped protective plate 319 to increase, thereby blocking higher waves and preventing erosion of the waterproof dam body 4.

When the driving wheel 3111 rotates, it will drive the driven wheel 3112 to rotate through the belt transmission, and the driven wheel 3112 will prompt the rotating rod 3113 to rotate. After the rotating rod 3113 rotates, it will drive the second bevel gear 3116 to rotate through the first bevel gear 3115. After the second bevel gear 3116 rotates, it will drive the screw 3118 to rotate through the transmission shaft 3117. Because the limiting column 3122 and the limiting block 3121 limit the displacement plate 3120 and the socket block 3119, the socket block 3119 will be prompted to move downward along the outer wall of the screw 3118, and drive the displacement plate 3120 to move downward, so that the bottom of the displacement plate 3120 contacts the top of the base plate 1, and the water flow is blocked by the displacement plate 3120 to prevent the water flow from penetrating the bottom of the waterproof dam body 4.

[0018] A preferred embodiment of an anti-seepage and water-stopping structure for water conservancy and hydropower projects provided by the present invention is as follows: Figures 1 to 6 As shown: an auxiliary component 32 is further provided above the base plate 1. The auxiliary component 32 includes a counterweight 321 fixedly connected to the left top. The counterweight 321 is located on the side of the waterproof dam body 4. A first support column 322 is fixedly connected to the left top of the waterproof dam body 4. A protective rod 323 is fixedly connected to the side wall of the first support column 322. The other end of the protective rod 323 is fixedly connected to a second support column 324. The bottom of the second support column 324 is fixedly connected to the top of the waterproof dam body 4.

[0021] Furthermore, there are a number of compression-resistant cross blocks 3110 , and the compression-resistant cross blocks 3110 are distributed in a circular array along the central axis of the arc-shaped protective plate 319 .

[0022] In addition, the surface of the waterproof dam body 4 is coated with a waterproof layer.

[0023] Working principle: In the process of waterproofing and stopping the waterproof dam body 4, it is necessary to block the water waves through the arc-shaped protective plate 319 and the pressure-resistant cross block 3110 to prevent high water waves from scouring the waterproof dam body 4 and causing erosion to the waterproof dam body 4. In order to block high water waves, it is necessary to adjust the protection height of the arc-shaped protective plate 319 against the water waves. At this time, the operator turns on the forward and reverse motor 312. When the forward and reverse motor 312 rotates forward, it will prompt the output shaft 313 to rotate forward.

The half-toothed ring 315 is limited by the limiting ring 316 and the connecting block 317, which causes the half-toothed ring 315 to rotate along the outer wall of the limiting ring 316. During the rotation of the half-toothed ring 315, the arc-shaped protective plate 319 is driven to tilt, causing the protective height of the arc-shaped protective plate 319 to increase, thereby blocking higher water waves and preventing erosion of the waterproof dam body 4; When the output shaft 313 rotates forward, it drives the driving wheel 3111 to rotate. When the driving wheel 3111 rotates, it drives the driven wheel 3112 to rotate through the belt transmission, and the driven wheel 3112 prompts the rotating rod 3113 to rotate. After the rotating rod 3113 rotates, it drives the second bevel gear 3116 to rotate through the first bevel gear 3115. After the second bevel gear 3116 rotates, it drives the screw rod 3118 to rotate through the transmission shaft 3117. Because the limiting column 3122 and the limiting block 3121 limit the displacement plate 3120 and the sleeve block 3119, the sleeve block 3119 is prompted to move downward along the outer wall of the screw rod 3118, and drive the displacement plate 3120 to move downward, so that the bottom of the displacement plate 3120 contacts the top of the base plate 1, and the displacement plate 3120 blocks the water flow, preventing the water flow from penetrating the bottom of the waterproof dam body 4; By setting the counterweight block 321, the waterproof dam body 4 can be evenly balanced to improve the stability of the waterproof dam body 4. By setting the first support column 322, the protective rod 323 and the second support column 324, the mutual cooperation between the first support column 322, the protective rod 323 and the second support column 324 can be utilized to increase the safety of the waterproof dam body 4.
