Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cast iron gates, in particular to a bidirectional rubber water-stop cast iron gate. Background Art
[0002] Cast iron gates are mainly composed of gate frames, gate plates, hangers and closing inclined irons. In order to overcome the shortcomings of steel gates that are prone to rust, the gate frames and gate plates are all made of cast iron, and the gate frame is composed of an upper crossbeam, a lower crossbeam, a left straight beam and a right straight beam. In order to facilitate manufacturing, transportation and installation, the gate plate is generally assembled from upper and lower parts according to its size or height. The gate is a control facility used to close and open the water discharge (release) channel. An important component of hydraulic structures, it can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. In the prior art, the gate plate and the gate frame in the bidirectional cast iron gate cannot be effectively sealed, resulting in water leakage, which in turn reduces the practicality of the bidirectional hydraulic cast iron gate. In addition, after being subjected to long-term hydraulic impact, the gate plate is easily deformed, which in turn reduces the service life of the bidirectional hydraulic cast iron gate. At the same time, during the use of the bidirectional water-stop cast iron gate, the gate plate of the water-facing surface of the gate plate is often broken and shattered under excessive water pressure due to the low structural firmness and strength of the gate plate, and the overall service life of the gate plate is short. Summary of the invention
[0003] To achieve the above objectives, the present invention is implemented through the following technical solutions: a bidirectional rubber water-stop cast iron gate, comprising a gate, the top of the gate is rotatably connected to an adjustment component, and the outer side of the adjustment component is rotatably connected to a rotating wheel; The gate seat supports and guides the gate. The gate is located inside the gate seat and is rotatably connected to the gate seat. Among them, the gate includes a fixed frame, which is slidably connected to the gate seat, the fixed frame is located inside the gate seat, an arc plate is arranged inside the fixed frame, a fixed block is arranged inside the fixed frame, a square plate is arranged inside the fixed frame, an elastic frame is fixedly connected to the outside of the fixed block, and arc plates are arranged on both sides of the fixed frame. By setting this shape design, it is helpful to achieve a good water-stopping effect under the action of water pressure in different directions. When one side is subjected to water pressure, the arc plate is stressed, and the side of the arc plate can better fit the rubber strip and the side wall of the gate chamber or other water-stopping structures. At the same time, due to the geometric shape of the arc, the water pressure will be evenly distributed on the surface of the gate along the curved surface. The arc-shaped contact surface with water can disperse the huge water pressure to a larger area, thereby reducing the situation of excessive local pressure. This uniform pressure distribution helps to improve the structural stability of the gate and reduce the risk of structural deformation or damage caused by excessive local pressure. The elastic frame is fixedly connected to a rubber strip on the side close to the arc plate, and an arc groove is opened on the side of the arc plate close to the rubber strip.
[0004] Preferably, there are two arc-shaped plates, which are symmetrically arranged with the fixed frame as the center, the fixed block and the square plate are located at the interval between the two arc-shaped plates, the outer side of the fixed block is fixedly connected to the limit plate, the limit plate is evenly distributed at the outer edge of the fixed block, the limit plate is located at the interval between the fixed block and the arc-shaped plate, the outer side of the fixed frame is rotatably connected to rollers, there are multiple rollers, and the multiple rollers are symmetrically arranged with the arc-shaped plate as the center, the elastic frame is made of rubber material, and the elastic frame contacts with the fixed block and the rectangular surface of the square plate to provide stable support. Under this contact mode, the elastic frame can evenly distribute pressure on the plane, and when the gate is subjected to water pressure, the contact of the rectangular surface allows a part of the rubber strip to be stable The rubber strip can effectively resist the pressure perpendicular to the plane direction, which helps to prevent the elastic frame from being over-extruded and deformed and losing its water-stopping function, and ensures that the rubber strip can maintain a good sealing state in the vertical direction. The arc contact between the rubber strip and the arc plate enhances the sealing effect and the adaptability to different working conditions. The arc shape enables the rubber strip to better fit the curved surface of the arc groove on the arc plate when it is squeezed by the arc plate. This fit can not only effectively prevent water leakage in a static state, but also when the shape of the arc plate changes due to temperature changes, structural deformation or uneven water pressure, the rubber strip can also deform accordingly and adaptively maintain the sealing state. The combination of rectangular surface contact and arc contact enables the rubber strip and the elastic frame to be in two different The geometric surface of the square plate plays a role, forming a synergistic effect. The rectangular surface contact ensures the stability of the elastic frame in the basic position, while the arc contact enhances the sealing ability of the rubber strip under dynamic and complex shapes. This synergistic effect can cope with various complex working conditions, including water pressure in different directions, small displacement of the gate, etc., thereby significantly improving the water-stopping effect. The elastic frame is located on the side of the limit plate close to the fixed frame, and the fixed frame and the square plate are connected through the elastic frame. A convex block is fixedly connected to the side of the fixed frame close to the elastic frame. The convex block is located at the interval between the elastic frame and the rubber strip. The contact surface between the fixed block and the square plate is wedge-shaped. The wedge-shaped contact part of the fixed block and the square plate can also play a role in water-stopping to a certain extent. Function: When the wedge-shaped contact between the two plates is tight, the gap between them can be effectively closed. At the same time, by installing a soft sealing strip at the wedge-shaped contact, the sealing strip can fill the gap by utilizing the extrusion effect of the wedge, thereby further improving the water-stopping performance and reducing water leakage. The combination of the arc plate and the wedge-shaped structure can enhance the gate's anti-bending ability. When the gate is subjected to uneven water pressure or external impact force, the arc structure can disperse the force, and the wedge-shaped contact part can resist bending deformation by extrusion between each other. This structure can effectively prevent the gate from bending due to impact force and ensure the normal operation of the gate. A sealing strip is fixedly connected to the side of the fixed block close to the square plate.
[0005] Preferably, the adjusting assembly includes a screw rod, the bottom of which is rotatably connected to the middle of the top of the fixed frame, the top of the screw rod passes through the top of the gate seat, a cylinder is provided on the outside of the screw rod, the cylinder is located inside the gate seat, and the cylinder is rotatably connected to the inside of the gate seat, and a spring is fixedly connected to the bottom of the cylinder. The staff operates the rotary wheel to rotate, and the rotary wheel drives the bottom fixed ring to rotate, and extrusion is generated between the fixed ring and the bottom circular ring. In the process of mutual extrusion between the protrusions between the fixed ring and the circular ring, the spring is forced to contract, so that the cylinder drives the internal ball to move inside the slide groove toward the direction close to the base, and the circular ring moves away from the fixed ring. At the same time, the ball is located inside the spiral groove outside the screw rod, and then the rotary wheel drives the screw to rotate, so that the screw drives the gate to move up and down, and the moving rotary wheel stops. Under the elasticity of the spring Under the action of force, the ring resets and meshes with the fixed ring through the protrusion. Due to the water pressure, an axial thrust is generated on the gate. Through the meshing between the ring and the fixed ring, the screw will not rotate automatically under the action of the axial force, thereby achieving self-locking. The self-locking function can ensure that the screw will not reverse under the action of this thrust, so that the gate remains in a closed state. The end of the spring away from the cylinder is fixedly connected to the gate seat, and the end of the cylinder away from the spring is fixedly connected with a ring. A rotating wheel is arranged on the outside of the screw, and a fixing ring is fixedly connected to the bottom of the rotating wheel. A protrusion is arranged on the contact surface between the fixing ring and the ring. A ball is rotatably connected to the inner wall of the cylinder. There are two balls, which are symmetrically arranged with the screw as the center. Slide grooves are symmetrically opened on the outside of the screw, and the balls are located inside the slide grooves.
[0006] Preferably, the gate seat includes a base, which is a frame arrangement, an inner cavity is opened inside the base, a fixed frame is located inside the inner cavity, and a side of the fixed frame is slidably connected to the inner cavity. The rotating wheel rotates, and the rotating wheel drives the screw to rotate, thereby driving the gate to move up and down. The water on the water-facing surface of the gate will accelerate the flow due to the change in the area of the water passage, thereby generating pressure. The pressure may generate resistance to the movement of the gate. Due to the wedge-shaped arrangement between the square plate and the fixed block, when the gate moves, the friction force is decomposed into two components along the inclined plane and the direction perpendicular to the inclined plane. The component in the direction perpendicular to the inclined plane will cause the gate and the distribution block to move. The contact between the combined parts is closer, and the component force along the inclined direction is conducive to the sliding of the gate. This force decomposition method reduces the thrust or pull required to move the gate under the same water pressure and gate weight conditions. At the same time, the water-facing surface is set to an arc shape, which effectively reduces the water pressure on the water-facing surface of the gate, improves the stability and firmness of the gate, and is conducive to the smooth lifting or lowering of the gate. The inner wall of the inner cavity is fixedly connected with a guide plate. There are multiple guide plates, and the multiple guide plates are symmetrically arranged with the roller as the center. The roller is located in the middle of the two guide plates, and a bent plate is fixedly connected to the side of the base close to the rubber strip.
[0007] The present invention provides a bidirectional rubber water-stop cast iron gate. It has the following beneficial effects: 1. The bidirectional rubber water-stop cast iron gate uses a combination of rectangular surface contact and arc contact to enable the rubber strip and the elastic frame to function on two different geometric surfaces, forming a synergistic effect. The rectangular surface contact ensures the stability of the elastic frame in the basic position, while the arc contact enhances the sealing ability of the rubber strip under dynamic and complex shapes. This synergistic effect can cope with various complex working conditions, including water pressure in different directions, small displacement of the gate, etc., thereby significantly improving the water-stopping effect.
[0008] 2. The two-way rubber water-stop cast iron gate installs soft sealing strips at the wedge contact point, and uses the extrusion effect of the wedge to fill the gap with the sealing strips, thereby further improving the water-stopping performance and reducing water leakage. The combination of the arc plate and the wedge structure can enhance the gate's anti-bending ability.
[0009] 3. The two-way rubber water-stop cast iron gate achieves self-locking by meshing between the circular ring and the fixed ring, so that the screw will not rotate automatically under the action of axial force. The self-locking function can ensure that the screw will not reverse under this thrust, so that the gate remains closed.
[0010] 4. The bidirectional rubber water-stop cast iron gate is wedge-shaped between the square plate and the fixed block. When the gate moves, the friction force is decomposed into two components along the inclined plane and perpendicular to the inclined plane. The component in the perpendicular inclined plane will make the contact between the gate and the mating parts closer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.
[0014] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: The gate 2, the top of the gate 2 is rotatably connected to an adjusting component 3, and the outer side of the adjusting component 3 is rotatably connected to a rotating wheel 4; A gate seat 1, which supports and guides a gate 2. The gate 2 is located inside the gate seat 1, and the gate 2 is rotatably connected to the gate seat 1; The gate 2 includes a fixed frame 21, which is slidably connected to the gate seat 1. The fixed frame 21 is located inside the gate seat 1. An arc plate 22 is arranged inside the fixed frame 21. A fixed block 23 is arranged inside the fixed frame 21. A square plate 24 is arranged inside the fixed frame 21. An elastic frame 28 is fixedly connected to the outer side of the fixed block 23. Arc plates 22 are arranged on both sides of the fixed frame 21. By setting this shape design, it is helpful to achieve a good water-stopping effect under the action of water pressure in different directions. When one side is subjected to water pressure, the arc plate 22 is stressed, and the side of the arc plate 22 can be better The rubber strip 27 fits snugly against the side wall of the gate chamber or other water-stopping structures. Due to the arc-shaped geometric shape, the water pressure will be evenly distributed on the gate surface along the curved surface. The arc-shaped surface in contact with water can disperse the huge water pressure to a larger area, thereby reducing the situation of excessive local pressure. This uniform pressure distribution helps to improve the structural stability of the gate and reduce the risk of structural deformation or damage caused by excessive local pressure. The elastic frame 28 is fixedly connected to the rubber strip 27 on one side close to the arc plate 22, and an arc groove 210 is opened on the side of the arc plate 22 close to the rubber strip 27.
[0015] There are two arc plates 22, which are symmetrically arranged with the fixed frame 21 as the center. The fixed block 23 and the square plate 24 are located at the interval between the two arc plates 22. The outer side of the fixed block 23 is fixedly connected with a limiting plate 26, and the limiting plate 26 is evenly distributed at the outer edge of the fixed block 23. The limiting plate 26 is located at the interval between the fixed block 23 and the arc plate 22. The outer side of the fixed frame 21 is rotatably connected with a roller 25. There are multiple rollers 25, and the multiple rollers 25 are symmetrically arranged with the arc plate 22 as the center. The elastic frame 28 is made of rubber material, and the elastic frame 28 contacts the rectangular surface of the fixed block 23 and the square plate 24 to provide stable support. In this contact mode, the elastic frame 28 can evenly distribute pressure on the plane. When the gate 2 is subjected to water pressure When the rubber strip 27 is in the airtight state, the contact of the rectangular surface enables a part of the rubber strip to firmly resist the pressure perpendicular to the plane direction, which helps to prevent the elastic frame 28 from being excessively squeezed and deformed and losing the water-stopping function, and ensures that the rubber strip can maintain a good sealing state in the vertical direction. The arc contact between the rubber strip 27 and the arc plate 22 enhances the sealing effect and the adaptability to different working conditions. The arc shape enables the rubber strip 27 to better fit the curved surface of the arc groove 210 on the arc plate 22 when it is squeezed by the arc plate 22. This fit can not only effectively prevent water leakage in a static state, but also when the arc plate changes shape due to temperature changes, structural deformation or uneven water pressure, the rubber strip can also deform accordingly to adaptively maintain the sealing state. The combination of rectangular surface contact and arc contact The combination makes the rubber strip 27 and the elastic frame 28 work on two different geometric shapes, forming a synergistic effect. The rectangular surface contact ensures the stability of the elastic frame 28 in the basic position, while the arc contact enhances the sealing ability of the rubber strip 27 under dynamic and complex shapes. This synergistic effect can cope with various complex working conditions, including water pressure in different directions, small displacement of the gate, etc., thereby significantly improving the water-stopping effect. The elastic frame 28 is located on the side of the limit plate 26 close to the fixed frame 21, and the fixed frame 21 and the square plate 24 are connected through the elastic frame 28. A convex block 29 is fixedly connected to the side of the fixed frame 21 close to the elastic frame 28. The convex block 29 is located at the interval between the elastic frame 28 and the rubber strip 27. The contact surface between the fixed block 23 and the square plate 24 is a wedge-shaped setting. The wedge-shaped contact part of the fixed block 23 and the square plate 24 can also play a role in water stopping to a certain extent. When the wedge-shaped contact between the two plates is tight, the gap between them can be effectively closed. At the same time, by installing a soft sealing strip 211 at the wedge-shaped contact, the sealing strip is filled with the gap by the squeezing effect of the wedge, which further improves the water-stopping performance and reduces water leakage. The combination of the arc plate 22 and the wedge-shaped structure can enhance the bending resistance of the gate 2. When the gate 2 is subjected to uneven water pressure or external impact force, the arc structure can disperse the force, and the wedge-shaped contact part can resist bending deformation by squeezing each other. This structure can effectively prevent the gate 2 from bending due to impact force and ensure the normal operation of the gate 2.A sealing strip 211 is fixedly connected to one side of the fixing block 23 close to the square plate 24.
[0016] The second embodiment is based on the first embodiment. Figures 7 and 8 As shown, the adjusting assembly 3 includes a screw rod 31, the bottom of which is rotatably connected to the middle of the top of the fixing frame 21, the top of the screw rod 31 passes through the top of the gate seat 1, a cylinder 34 is arranged on the outside of the screw rod 31, the cylinder 34 is located inside the gate seat 1, and the cylinder 34 is rotatably connected to the inside of the gate seat 1, and a spring 36 is fixedly connected to the bottom of the cylinder 34. The staff operates the rotating wheel 4 to rotate, and the rotating wheel 4 drives the bottom fixing ring 33 to rotate, and extrusion is generated between the fixing ring 33 and the bottom circular ring 35. In the process of mutual extrusion between the protrusions between the fixing ring 33 and the circular ring 35, the spring 36 is contracted by force, so that the cylinder 34 drives the internal ball 37 to move in the direction close to the base 11 inside the sliding groove 32, and the circular ring 35 is away from the fixing ring 33. At the same time, the ball 37 is located inside the spiral groove outside the screw rod 31, and then the rotating wheel 4 drives the screw rod 31 to rotate, so that the screw 31 drives the gate 2 to move up and down, and the moving wheel stops. Under the elastic force of 36, the ring 35 is reset and meshed with the fixing ring 33 through the protrusion. Due to the water pressure, an axial thrust is generated on the gate. Through the meshing between the ring 35 and the fixing ring 33, the screw 31 will not automatically rotate under the action of the axial force, thereby realizing self-locking. The self-locking function can ensure that the screw 31 will not reverse under the action of this thrust, so that the gate 2 remains in a closed state. The end of the spring 36 away from the cylinder 34 is fixedly connected to the gate seat 1, and the end of the cylinder 34 away from the spring 36 is fixedly connected with the ring 35. The outer side of the screw 31 is provided with a rotating wheel 4, and the bottom of the rotating wheel 4 is fixedly connected with the fixing ring 33. The contact surface between the fixing ring 33 and the ring 35 is provided with a protrusion. The inner wall of the cylinder 34 is rotatably connected with a ball 37. There are two balls 37, and the two balls 37 are symmetrically arranged with the screw 31 as the center. The outer side of the screw 31 is symmetrically provided with a slide groove 32, and the ball 37 is located inside the slide groove 32.
[0017] The third embodiment is based on the first and second embodiments. Fig. 9As shown, the gate seat 1 includes a base 11, which is a frame arrangement. An inner cavity 12 is opened inside the base 11. A fixed frame 21 is located inside the inner cavity 12. The side of the fixed frame 21 is slidably connected to the inner cavity 12. The runner 4 rotates, and the runner 4 drives the screw 31 to rotate, thereby driving the gate 2 to move up and down. The water on the water-facing surface of the gate 2 will accelerate the flow due to the change in the area of the water passage, thereby generating pressure. The pressure may generate resistance to the movement of the gate 2. Due to the wedge-shaped arrangement between the square plate 24 and the fixed block 23, when the gate 2 moves, the friction force is decomposed into two components along the inclined plane and perpendicular to the inclined plane. The component in the direction of the perpendicular inclined plane will cause the gate 2 to move. The contact between the gate 2 and the mating parts is closer, and the component force along the inclined surface is beneficial to the sliding of the gate 2. This force decomposition method reduces the thrust or pull required to move the gate under the same water pressure and gate weight conditions. At the same time, the water-facing surface is set to an arc shape, which effectively reduces the water pressure on the water-facing surface of the gate 2, improves the stability and firmness of the gate 2, and is conducive to the smooth lifting or lowering of the gate 2. The inner wall of the inner cavity 12 is fixedly connected with a guide plate 13. There are multiple guide plates 13, and the multiple guide plates 13 are symmetrically arranged with the roller 25 as the center. The roller 25 is located in the middle of the two guide plates 13, and the base 11 is fixedly connected to the side close to the rubber strip 27 with a bent plate 14.
[0018] When in use, the staff operates the wheel 4 to rotate, and the wheel 4 drives the bottom fixed ring 33 to rotate, and extrusion is generated between the fixed ring 33 and the bottom circular ring 35. In the process of mutual extrusion between the protrusions between the fixed ring 33 and the circular ring 35, the spring 36 is forced to shrink, so that the cylinder 34 drives the internal ball 37 to move inside the slide groove 32 toward the direction close to the base 11, and the circular ring 35 moves away from the fixed ring 33. At the same time, the ball 37 is located inside the spiral groove outside the screw 31. Then the wheel 4 drives the screw 31 to rotate, so that the screw 31 drives the gate 2 to move up and down.
