Description

Technical Field

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

[0002] Anti-seepage technology is crucial in water conservancy and hydropower projects. It reduces or prevents water from penetrating through the project structure, improves the density and durability of the project structure, and prevents water from eroding and damaging the project structure, thereby ensuring the normal operation and service life of the project. According to the laws of physics, when the anti-seepage water board is subjected to water flow pressure, the pressure generally has two effects: the first is to rotate the water stop board along the bottom end point of the facade, and the second is to make the water stop board as a whole translate inward along the direction of the water flow; however, the rotating structure has an overturning effect on the water stop board, and the inward translation will cause the water stop board to be dislocated, resulting in water seepage.

[0003] At present, the anti-seepage board is installed by fixing piles, and the bottom of the anti-seepage board is fixed with electrical equipment to achieve the stability of the anti-seepage water-stopping device. However, since the anti-seepage board is placed on the dam body all year round during use, its surface will be frequently impacted and corroded by running water. If the electrical equipment or electronic components are damaged, it will affect the use effect of the device. Therefore, the prior art further improves the anti-seepage board.

[0004] In the patent application number CN202211088390.3, the linkage effect of the gear mechanism enables the device to only use the pressure generated by the impact of the water flow for thrust fixation, reducing the difficulty of maintenance caused by the use of electronic equipment. However, since gear transmission has high requirements for manufacturing and installation accuracy, it will increase the manufacturing cost and installation difficulty; and the above device uses incomplete gears. Although the incomplete gears are flexible in design, they are complicated to process, and there is a sudden change in speed when entering and exiting the meshing, which is easy to cause rigid impact. Summary of the invention

[0005] The object of the present invention is to provide an anti-seepage water-stopping device for water conservancy and hydropower engineering, which can convert the lateral force of water flow impact into a longitudinal downward extending force through the mutual cooperation of a locking part and a movable rod, thereby improving the stability of the device; and can achieve reverse fixation of an anti-seepage plate through the mutual cooperation of special-shaped parts, movable parts and a push-back rod, and achieve the push-back of the anti-seepage plate through a simple resistance effect, and has a better application scenario; at the same time, the use of a purely mechanical structure can avoid the difficulty of inconvenient maintenance of electronic equipment.

[0028] 2. In the present invention, by converting the lateral pressure generated by the impact of water flow into the power for the locking piece to extend downward, it can be concluded that the impact force of the water flow and the downward force of the locking piece are proportional. The greater the impact force of the water flow, the deeper the locking piece is inserted into the ground, thereby ensuring the overall stability of the device.

At this time, the push-back rod drives the abutment blocks 2 and 3 to extrude the anti-seepage plate. The above structure makes it possible for the greater the impact force of the water flow, the greater the push-back force of the abutment blocks 2 and 3 on the anti-seepage plate, thereby ensuring the stability of the device when in use.

[0030] 4. In the present invention, when the annular plate rotates, the wave groove is driven to rotate synchronously. At this time, the contact surface between the extrusion rod and the wave groove keeps changing. When the low surface in the wave groove contacts the extrusion rod, the extrusion plate on the extrusion rod is in the lowest position. When the curved surface in the wave groove contacts the extrusion rod, the extrusion plate on the extrusion rod is in the middle position. When the high surface in the wave groove contacts the extrusion rod, the extrusion plate on the extrusion rod is in the highest position. In this way, different extrusion forces can be generated on the anti-seepage plate. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0043] The embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0044] Please refer to Figure 1-Figure 10 , which shows the overall structural schematic diagram of the anti - seepage and water - stop device for water conservancy and hydropower projects.

[0045] This embodiment provides an anti - seepage and water - stop device for water conservancy and hydropower projects, including a bottom plate 100. One end of the bottom plate 100 is inclined and provided with an anti - seepage plate 101 integrally formed with the bottom plate 100. The slope of the surface of the anti - seepage plate 101 is the same as the slope of the corresponding dam body. The top surface of the bottom plate 100 is provided with a fixing frame 102 and a movable rod 103. One end of the movable rod 103 is provided with a contact block one 104 that abuts against the inner wall of the anti - seepage plate 101. The other end of the movable rod 103 movably penetrates through the fixing frame 102 and is connected to a pushing - back mechanism 300 arranged on the bottom plate 100.

[0046] The fixed frame 102 is provided with a locking mechanism 200, which includes a locking piece 201 that vertically moves through the fixed frame 102 and the bottom plate 100, and a first locking portion 202 is provided on the side wall of the locking piece 201 opposite to the movable rod 103; an auxiliary structure 203 that cooperates with the first locking portion 202 is provided on the outer wall of the movable rod 103, and the auxiliary structure 203 is used to drive the locking piece 201 to move downward through the first locking portion 202 when the anti-seepage plate 101 is impacted by water flow and causes the movable rod 103 to move horizontally;

[0047] The push-back mechanism 300 includes a support member 301, a movable member 302, a special-shaped member 303 and a push-back rod 304. The support member 301 is fixedly connected to one end of the fixed frame 102 away from the anti-seepage plate 101; the movable member 302 is elastically slidably arranged in the support member 301, and one end of the movable member 302 abuts against the movable rod 103, and the other end of the movable member 302 is at a certain distance from the inner end surface of the support member 301, and the inner wall of the movable member 302 is provided with a pressing portion 305; One end of the push-back rod 304 is movably inserted into the movable part 302, and the other end extends to the outside of the support part 301 and is connected to the push-back assembly 306; the push-back assembly 306 extends toward one end of the anti-water seepage plate 101 and abuts against the anti-water seepage plate 101; the special-shaped part 303 radially and obliquely penetrates the push-back rod 304 and cooperates with the extrusion part 305, so that the extrusion part 305 can extrude the special-shaped part 303 and drive the push-back rod 304 to move axially toward one end of the anti-water seepage plate 101.

[0048] Next, the anti-seepage and water-stopping device for water conservancy and hydropower engineering according to this exemplary embodiment will be further described.

[0049] In some embodiments, reference Figure 1 A fixed frame 102 is arranged near the middle position on the top surface of the bottom plate 100, and the fixed frame 102 is an inverted U-shaped structure; a movable rod 103 is movably arranged on the opposite side of the fixed frame 102, and a resistance block 104 is arranged at one end of the movable rod 103 to abut against the inclined inner wall of the anti-seepage plate 101; the other end of the movable rod 103 is arranged inside the fixed frame 102, and can pass through the fixed frame 102 during its movement, and cooperate with the push-back mechanism 300 arranged on the bottom plate 100 to generate a push-back force on the anti-seepage plate 101.

[0050] Reference Figure 2-Figure 4The above-mentioned fixed frame 102 is provided with a locking mechanism 200, and the locking mechanism 200 includes a locking piece 201 that vertically moves through the fixed frame 102 and the bottom plate 100, and the side wall of the locking piece 201 opposite to the movable rod 103 is provided with a first locking portion 202; the outer wall of the movable rod 103 is provided with an auxiliary structure 203 that cooperates with the first locking portion 202, and the auxiliary structure 203 is used to drive the locking piece 201 to move downward through the first locking portion 202 when the anti-seepage plate 101 is impacted by water flow and causes the movable rod 103 to move laterally. That is, when the anti-seepage plate 101 is impacted by water flow, the impact force of the water flow causes the resistance block 104 to move away from the anti-seepage plate 101, thereby synchronously driving the movable rod 103 to move. At this time, the locking member 201 and the auxiliary structure 203 cooperate to convert the lateral pressure generated by the water flow impact into the power for the locking member 201 to extend downward. The greater the impact force of the water flow, the deeper the locking member 201 is inserted into the ground, thereby limiting the overall stability of the device.

[0051] As a preferred embodiment, the locking member 201 includes two locking anchors, and the bottom of the locking anchors is a conical structure to ensure stability during insertion. The two locking anchors are arranged in parallel along the width direction of the bottom plate 100 (i.e., perpendicular to the water flow direction), and the two locking anchors are respectively located on both sides of the movable rod 103; the arrangement of the two locking anchors can balance the movable rod 103 and improve the stability of the device during insertion. The auxiliary structure 203 is an auxiliary groove opened on the outer wall of the movable rod 103 along the axial direction, such as Figure 5 As shown. Two auxiliary grooves are provided and the two auxiliary grooves are symmetrically arranged on opposite sides of the movable rod 103. The auxiliary grooves gradually rise along the end close to the anti-seepage plate 101 to the other end, that is, they are arc-shaped grooves extending axially upward along the outer wall of the movable rod 103; the first locking part 202 is an auxiliary protrusion provided on the outer wall of the locking anchor, and the auxiliary protrusion is slidably connected in the auxiliary groove, so that when the movable rod 103 moves away from the end of the anti-seepage plate 101 (hereinafter referred to as "leftward"), the auxiliary protrusion slides from a high position to a low position in the auxiliary groove, thereby driving the auxiliary protrusion to move downward, and driving the locking anchor to move downward. Through the above structure, when the movable rod 103 is impacted by water flow, it moves to the left side, driving the auxiliary protrusion to move downward, thereby driving the locking anchor to move downward. The greater the impact force of the water flow, the more displacement of the movable rod 103 to the left, and the deeper the locking anchor moves downward, thereby firmly restricting the entire device.

[0052] As a preferred implementation method, refer to Figure 6 The top of the fixing frame 102 is provided with two through holes 102a for two locking anchors to pass through, and the inner wall of the two through holes 102a close to each other is provided with a limiting hole 102b; Figure 2The two locking anchors are provided with a limit strip 204 on one side opposite to the other, and the limit strip 204 is inserted into the limit hole 102b. The limit strip 204 is correspondingly slidably connected in the limit hole 102b, so that the locking anchor cannot deflect and can only move in the vertical direction, thereby improving the stability of the locking anchor when inserted.

[0053] Furthermore, a connecting rod 205 is connected between the opposite side walls of the two locking anchors near their tops, and the two locking anchors are connected as a whole through the connecting rod 205, so that the two locking anchors can move up and down synchronously while avoiding deflection, thereby further improving the stability of the device body.

[0054] In some embodiments, reference Figure 1 , Figure 5 and Figure 7 The above-mentioned push-back mechanism 300 includes a support member 301, a movable member 302, a special-shaped member 303 and a push-back rod 304. The support member 301 is fixedly connected to one end of the fixed frame 102 away from the anti-seepage plate 101; the movable member 302 is elastically slidably penetrated into the support member 301 and one end of the movable member 302 abuts against the movable rod 103, and the other end of the movable member 302 has a preset distance from the inner end surface of the support member 301, so that when the movable rod 103 moves to the left, it can push the movable member 302 to move a certain distance inside the support member 301, and after the movable rod 103 releases the thrust, the movable member 302 can return to its original position. One end of the push-back rod 304 is movably inserted into the movable member 302, and the other end extends to the outside of the support member 301 and is connected to a push-back assembly 306. The push-back assembly 306 extends toward one end of the water-proof plate 101 and abuts against the water-proof plate 101, that is, the push-back rod 304 can move in the movable member 302 and drive the push-back assembly 306 to move synchronously, so that the push-back assembly 306 generates a push-back force on the water-proof plate 101, thereby abutting the water-proof plate 101. An extrusion portion 305 is provided on the inner wall of the movable member 302, and the special-shaped member 303 radially and obliquely penetrates the push-back rod 304 and cooperates with the extrusion portion 305, so that the extrusion portion 305 can squeeze the special-shaped member 303 and drive the push-back rod 304 to move axially toward one end of the water-proof plate 101.

[0055] That is, when the movable rod 103 pushes the movable part 302 to move to the left, the extrusion portion 305 of its inner wall can squeeze the special-shaped part 303. The special-shaped part 303 is arranged in the push back rod 304 along the radial direction of the push back rod 304, so that it can generate an axial movement force on the push back rod 304. By setting its inclination direction, it can push the push back rod 304 to move toward the side of the anti-seepage plate 101, and then drive the push back assembly 306 to move toward the side of the anti-seepage plate 101 to produce resistance to it.

[0056] As a preferred embodiment, the support member 301 can be configured as a support tube 301a of a cylindrical structure, one end of the support tube 301a is provided with a through hole for the movable rod 103 to pass through, and the end is fixedly connected to the end surface of the fixed frame 102, so that the movable rod 103 can push the movable member 302 inside it, and the fixed support tube 301a can provide support for the movement of the movable member 302 and the push-back rod 304 to generate a reverse force. The other end of the support tube 301a is provided with a through hole for the push-back rod 304 to pass through.

[0057] The movable member 302 may be a movable cylinder with a cylindrical structure. The movable cylinder is movably arranged in the support cylinder 301a and its length is less than that of the support cylinder 301a, so that it can move in the support cylinder 301a. One end of the movable cylinder is closed and the other end is open. The closed end of the movable cylinder is close to the fixed frame 102 and can be flush with the end surface of the support cylinder 301a, that is, it abuts against the end surface of the fixed frame 102. At this time, the movable rod 103 is located in the fixed frame 102. When it moves to the left, it passes through the hole on the end surface of the fixed frame 102 and pushes the movable cylinder to move in the support cylinder 301a. Figure 7 and Figure 8 The inner wall of the opening end of the movable cylinder is provided with a first extrusion block 305a and a second extrusion block 305b opposite to each other; the opposite surfaces of the first extrusion block 305a and the second extrusion block 305b are inclined extrusion surfaces 305c with the same inclination direction. Since the inclination directions of the two inclined extrusion surfaces 305c are the same, only one of the inclined extrusion surfaces 305c is used to extrude the special-shaped part 303, and the other inclined extrusion surface 305c is used to make way for the special-shaped part 303, so that the special-shaped part 303 can move horizontally along the radial direction of the push back rod 304.

[0058] Reference Figure 7 The end of the support tube 301a away from the fixed frame 102 is fixedly connected to the fixed tube 301b, and the fixed tube 301b is inserted through the open end of the movable tube and a compression spring 307 is abutted against the closed end of the movable tube; so that the movable rod 103 can squeeze the compression spring 307 when pushing the movable tube to move. When the movable rod 103 releases the thrust, the compression spring 307 is reset, and the movable tube is driven to reset. Figure 5 and Figure 7, rectangular movable holes 301c are provided on opposite sides of the fixed cylinder 301b; the push-back rod 304 is movably arranged in the fixed cylinder 301b, and the push-back rod 304 is provided with an inclined through hole 304a opposite to and connected to the movable hole 301c. The inclined through hole 304a is a hole that passes through the opposite sides of the push-back rod 304 and is inclined along its radial direction. The special-shaped member 303 is arranged in the inclined through hole 304a, and the two ends of the special-shaped member 303 are respectively matched with the two inclined extrusion surfaces 305c. The matching relationship of the inclined through hole 304a, the special-shaped member 303 and the two inclined extrusion surfaces 305c is as shown in FIG. Figure 7 As shown, the three cooperate with each other. When the movable rod 103 pushes the movable cylinder to move to the left, the inclined extrusion surface 305c of the first extrusion block 305a squeezes one end of the special-shaped part 303 that fits therewith, and the inclined extrusion surface 305c of the second extrusion block 305b makes way for the other end of the special-shaped part 303, so that it can move horizontally. Since the special-shaped part 303 is tiltedly arranged in the inclined through hole 304a in the push back rod 304, the horizontal movement of the special-shaped part 303 along its radial direction is converted into the movement of the push back rod 304 along its axial direction, and moves toward one end of the anti-seepage plate 101 in the opposite direction to the moving direction of the movable cylinder.

[0059] As a preferred implementation method, refer to Fig. 9 The above-mentioned special-shaped member 303 is in a Z shape, including an inclined block 303a and a first wedge block 303b and a second wedge block 303c arranged at both ends of the inclined block 303a; the first wedge block 303b and the second wedge block 303c are respectively provided with an inclined surface 303d adapted to the inclined extrusion surface 305c on the side away from each other, and the first wedge block 303b and the second wedge block 303c are in contact with the end surface of the movable hole 301c on the side away from the inclined block 303a, that is, the first wedge block 303b and the second wedge block 303c are in contact with the end surface of the movable hole 301c ... and the first wedge block 303b and the second wedge block 303c are in contact with the end surface of the movable hole 301c, and the first wedge block 303b and the second wedge block 303c are in contact with the end surface of the movable hole 301c, and the first wedge block 303b and the second wedge block 303c are in contact with the end surface of the movable hole 301c, and the first wedge block 303b and the second wedge block 303c are in contact with the end surface of the movable hole 301c, and the first wedge block 303b and the second wedge block 303c The axial length of block 303c along the push back rod 304 is adapted to the length of the movable hole 301c, so that the movable hole 301c can limit it axially, so that the first wedge block 303b and the second wedge block 303c can only move along the radial direction of the push back rod 304, but cannot move along its axial direction. In this way, when the movable cylinder moves to the left, the push back rod 304 can be pushed to move toward the side opposite to the movement direction of the movable cylinder due to the movement of the inclined block 303a in the inclined through hole 304a.

[0060] As a preferred implementation method, refer to Figure 3 and Figure 5The push-back assembly 306 includes a linkage plate 306a, a first linkage rod 306b and a second linkage rod 306c. The linkage plate 306a is connected to one end of the push-back rod 304 away from the support tube 301a. The movement of the push-back rod 304 can drive the linkage plate 306a to move toward one end of the anti-seepage plate 101. The first linkage rod 306b and the second linkage rod 306c are respectively located on both sides of the fixed frame 102, and one end thereof is connected to the linkage plate 306a, and the other end thereof is respectively connected to the second and third abutment blocks 306d and 306e. When the linkage plate 306a moves toward one end of the anti-seepage plate 101, it can drive the first linkage rod 306b and the second linkage rod 306c to move synchronously, and then drive the second and third abutment blocks 306d and 306e to move synchronously toward one side of the anti-seepage plate 101 to abut against the anti-seepage plate 101. When the impact force of the water flow is greater, the push back force of the second and third blocks 306d and 306e on the water seepage prevention plate 101 is greater, thereby ensuring the stability of the device when in use. The pressure generated by the impact of the water flow plays a role in resisting and fixing the water seepage prevention plate 101.

[0061] Compared with the prior art which uses gear meshing for transmission, the push-back mechanism 300 of the present device realizes the reverse fixation of the anti-water seepage plate 101 through the force brought by the movement of the tilting block 303a, thereby simplifying the structure and using a simple resistance effect to realize the push-back of the anti-water seepage plate 101, which has a better application scenario.

[0062] In some embodiments, reference Figure 1 and Figure 2 The bottom plate 100 is also provided with a resistance mechanism 400, which includes a telescopic member 401, a pressing member 402 and a ring member 403 rotatably arranged on the top of the fixed frame 102; the locking member 201 is surrounded by the ring member 403. Figure 4The side wall of the locking member 201 opposite to the annular member 403 is provided with a second locking portion 404; the inner wall of the annular member 403 is provided with a deflection structure 405 matched with the second locking portion 404, and the deflection structure 405 is used to drive the annular member 403 to rotate through the second locking portion 404 when the locking member 201 moves downward. The top surface of the annular member 403 close to the anti-seepage board 101 is provided with a wave structure 406; the telescopic member 401 is arranged on the bottom plate 100 and is located between the fixed frame 102 and the anti-seepage board 101; the extrusion member 402 is connected to the top of the telescopic member 401, one end of the extrusion member 402 abuts against the inner wall of the anti-seepage board 101, and the other end of the extrusion member 402 abuts against the wave surface of the wave structure 406. When the locking member 201 moves downward, the second locking portion 404 and the deflection structure 405 cooperate to make the annular member 403 rotate on the top surface of the fixed model, driving the wave mechanism to rotate, so that the extrusion member 402 rises and falls on the wave surface, and the telescopic member 401 supports the extrusion member 402 and can synchronously extend and retract when the extrusion member 402 rises and falls; the extrusion member 402 rises and falls, so that one end of it produces different extrusion forces on the anti-seepage plate 101.

[0063] As a preferred implementation method, refer to Figure 2 The above-mentioned annular member 403 includes an annular plate 403a, an annular strip 403b is provided at the bottom of the annular plate 403a, an annular groove 102c is opened on the top surface of the fixed frame 102, and the annular strip 403b is slidably connected in the annular groove 102c, so that the annular plate 403a can rotate on the top surface of the fixed frame 102.

[0064] As a preferred implementation method, refer to Figure 2 and Figure 6 The above-mentioned deflection structure 405 is a deflection groove provided on the inner wall of the annular plate 403a. Two deflection grooves are provided and the two deflection grooves are relatively provided on the inner wall of the annular plate 403a. The two deflection grooves gradually rise in a clockwise or counterclockwise direction along the annular plate 403a; that is, although the two deflection grooves are relatively provided, their rotation directions are consistent, so that the annular plate 403a can rotate in one direction. The above-mentioned second locking part 404 is a deflection block provided on the outer wall of the locking anchor, and the deflection block is slidably connected in the deflection groove. When the locking anchor moves downward, the deflection block is driven to move downward synchronously. Since the locking anchor can only move vertically, the deflection block can drive the annular plate 403a to rotate. At this time, the deflection block slides from a high point to a low point in the deflection groove.

[0065] As a preferred implementation method, refer to Figure 2The telescopic member 401 includes a first telescopic rod 401a and a second telescopic rod 401b disposed on the bottom plate 100; the movable rod 103 is provided with two sliding holes 103a extending along its axial direction; the tops of the first telescopic rod 401a and the second telescopic rod 401b respectively pass through the two sliding holes 103a and are connected to a mounting frame 401c; the mounting frame 401c is provided with a notch, and the extrusion member 402 is passed through and fixed in the notch. By arranging two telescopic rods in parallel, the supporting force of the extrusion member 402 can be increased; by correspondingly providing two sliding holes 103a on the movable rod 103, when the movable rod 103 moves axially, the telescopic rod can give way to avoid interference between the telescopic rod and the movable rod 103.

[0066] As a preferred implementation method, refer to Figure 2 The extrusion member 402 includes an extrusion plate 402a, one end of which is provided with a wedge-shaped portion 402b integrally formed therewith, the slope of the wedge-shaped portion 402b is consistent with the slope of the anti-seepage plate 101 and abuts against the inner wall of the anti-seepage plate 101; the other end of the extrusion plate 402a is integrally connected with an extrusion rod 402c, and the extrusion rod 402c abuts against the wave surface of the wave structure 406. The wedge-shaped portion 402b at one end of the extrusion plate 402a can be adapted to the anti-seepage plate 101 and produce resistance thereto, and the end of the extrusion rod 402c at the other end can be in an arc shape, so that it can move flexibly on the wave surface. When the extrusion rod 402c in the extrusion plate 402a is subjected to an upward resistance force, the resistance portion squeezes the inner plate surface of the anti-seepage plate 101, thereby ensuring the stability of the anti-seepage plate 101 when in use.

[0067] As a preferred implementation method, refer to Figure 6 and Fig.10 The wave structure 406 includes a wave groove opened on the top surface of one side of the annular plate 403a, and the wave groove includes a high surface 406a, a curved surface 406b and a low surface 406c. The high surface 406a is connected to the high side of the curved surface 406b, and the low surface 406c is connected to the low side of the curved surface 406b. When the annular plate 403a rotates, the contact surface between the extrusion rod 402c and the wave groove changes continuously. Specifically, when the low surface 406c in the wave groove contacts the extrusion rod 402c, the extrusion plate 402a on the extrusion rod 402c is in the lowest position; when the curved surface 406b in the wave groove contacts the extrusion rod 402c, the extrusion plate 402a on the extrusion rod 402c is in the middle position; when the high surface 406a in the wave groove contacts the extrusion rod 402c, the extrusion plate 402a on the extrusion rod 402c is in the highest position, thereby generating different extrusion forces on the anti-seepage plate 101.

[0068] The device uses the pressure generated by the impact of water flow to resist and fix the anti-seepage plate 101, which not only avoids the difficulty of inconvenient maintenance of electronic equipment, but also combines the locking mechanism 200, the resistance mechanism 400 and the push-back mechanism 300 together to achieve hierarchical fixation of the anti-seepage plate 101. Compared with the prior art that uses gear meshing to transmit power, the device uses the force brought by the inclined block 303a moving in the inclined through hole 304a to achieve reverse fixation of the anti-seepage plate 101, thereby simplifying the structure and using a simple resistance effect to achieve the push-back of the anti-seepage plate 101, which has a better application scenario.
