Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering equipment, in particular to a water seepage prevention device for water conservancy engineering construction. Background Art

[0002] In the field of water conservancy project construction, anti-seepage technology has always been a key link in ensuring the quality and safety of the project. As the scale of water conservancy projects continues to expand, the construction environment involved has become increasingly complex, especially in areas with high incidence of seepage such as soft soil foundations, and the performance requirements for anti-seepage devices are increasing. Once water seepage problems occur in dams, channels and other facilities in water conservancy projects, it will not only cause a waste of water resources, but also cause a decrease in structural stability, and even lead to serious safety accidents such as dam breaches. Therefore, the development of efficient and reliable anti-seepage devices has become an important issue that needs to be urgently addressed in the field of water conservancy projects.

[0003] At present, common water conservancy project construction anti-seepage devices mostly use fixed baffle structures or sandbags, which are directly inserted into the foundation to block water infiltration. This type of device mainly relies on the material and insertion depth of the baffle itself to achieve the anti-seepage function. Some devices will set a waterproof layer on the surface of the baffle to enhance the anti-seepage effect. Its structural principle is based on physical barriers, using the density of the baffle to prevent water from passing through, and the waterproof layer further reduces the water penetration path. However, this traditional anti-seepage device has many limitations in practical applications.

[0004] In actual water conservancy project scenarios, such as the soft soil foundation areas involved in river diversion projects, traditional fixed anti-seepage devices are difficult to adapt to the complex and changeable water flow environment. When encountering strong water flow impact, the fixed baffle cannot effectively disperse the impact force of the water flow due to its limited contact area, causing the device to easily loosen or even be washed out of place by the water flow, thereby losing its anti-seepage function. At the same time, its single physical barrier method cannot adjust the anti-seepage structure in time when facing soil particle loss, foundation settlement, etc., which gradually aggravates the seepage problem. Therefore, the present invention provides a water conservancy project construction anti-seepage device to solve the shortcomings of the prior art. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a water conservancy project construction anti-seepage device, which solves the problem that the water conservancy project construction anti-seepage device in the prior art is difficult to be stable and easily displaced when impacted by strong water flow.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A water seepage prevention device for water conservancy project construction, including a baffle. A wing expansion mechanism is arranged on the outer side of the baffle. The wing expansion mechanism includes a rotating shaft and two first rack plates.

The outer side of the first rack plate is slidably connected to the inner side of the sliding groove. A limiting strip is fixedly connected to the outer side of the first rack plate. A limiting groove is opened on the inner side of the sliding groove. The outer side of the limiting strip is slidably connected to the inner side of the limiting groove.

[0007] Preferably, one end of the first rack plate is fixedly connected with a connecting block. A wing plate is fixedly connected to the outer side of the connecting block.

[0008] Preferably, a limiting cylinder is fixedly connected to the outer side of the baffle. A second rack plate is slidably connected to the inner side of the limiting cylinder. The outer side of the second rack plate is meshed with the second cylindrical gear.

[0009] Preferably, two fixing blocks are fixedly connected to the outer side of the baffle. A guide rod is fixedly connected to the outer side of the fixing block. A combined groove is opened inside the wing plate. The outer side of the guide rod is slidably connected to the inner wall of the combined groove.

[0010] Preferably, a positioning mechanism is arranged at one end of the second rack plate. The positioning mechanism includes a mounting block and a connecting frame. The outer side of the mounting block is fixedly connected to one end of the second rack plate. A grip rod is fixedly connected to the outer side of the mounting block.

[0011] Preferably, the top of the connecting frame is fixedly connected to the bottom of the mounting block. An activity groove is opened inside the connecting frame. A plurality of positioning holes are opened on the inner wall of the activity groove.

[0012] Preferably, a T-shaped rod is slidably connected to the through hole on the inner wall of the activity groove. A jack is opened inside the T-shaped rod. A plug pin is slidably connected to the inner side of the jack.

[0013] Preferably, two connecting pieces are fixedly connected to the bottom of the T-shaped rod. Two rotating blocks are rotatably connected to the inner sides of the two connecting pieces. A conical block is fixedly connected to the outer side of the rotating block. An arc-shaped block is fixedly connected to the outer side of the conical block.

[0017] 2. Through the mutual cooperation of the guiding block and the diversion grooves on the wing plate, the present invention forms a unique water flow guiding system. When the water flow impacts the device, it is initially diverted by the slope of the guiding block and then further dispersed by the diversion grooves, dispersing the water flow impact force over a larger area, avoiding the direct impact of the water flow on the baffle and the wing plate.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to the appendix Figure 1 - Appendix Figure 9, an embodiment of the present invention provides a water conservancy project construction anti-seepage device, including a baffle 1. A wing expansion mechanism 2 is arranged on the outer side of the baffle 1. The wing expansion mechanism 2 includes a rotating shaft 201 and two rack plates 204. One end of the rotating shaft 201 is rotatably connected to the outer side of the baffle 1. A first cylindrical gear 202 and a second cylindrical gear 203 are fixedly connected to the outer side of the rotating shaft 201. The outer side of the first cylindrical gear 202 is meshed with the two rack plates 204 at the same time. Two sliding grooves 207 are opened on the outer side of the baffle 1. The outer side of the rack plate 204 is slidably connected to the inner side of the sliding groove 207. To prevent the rack plate 204 from shifting during the sliding process, a limiting strip 206 is fixedly connected to the outer side of the rack plate 204, and a limiting groove 208 is opened on the inner side of the sliding groove 207. The outer side of the limiting strip 206 is slidably connected to the inner side of the limiting groove 208. One end of the rack plate 204 is fixedly connected with a connecting block 205, and a wing plate 209 is fixedly connected to the outer side of the connecting block 205. The outer side of the wing plate 209 is slidably connected to the outer side of the baffle 1. When actually in use, hold the grip 602 and pull the entire positioning mechanism 6. Since the mounting block 601 is fixed to one end of the rack plate 211, the grip 602 drives the mounting block 601 to move downward, and then the rack plate 211 slides downward in the limiting cylinder 210. The rack plate 211 is meshed with the second cylindrical gear 203. As the rack plate 211 moves downward, the second cylindrical gear 203 starts to rotate. Because one end of the rotating shaft 201 is rotatably connected to the outer side of the baffle 1, and the first cylindrical gear 202 and the second cylindrical gear 203 are fixed on the rotating shaft 201, the rotation of the second cylindrical gear 203 will drive the first cylindrical gear 202 to rotate synchronously through the rotating shaft 201. The first cylindrical gear 202 is meshed with the two rack plates 204, so that the rack plate 204 slides in the sliding groove 207. As the rack plate 204 moves, the connecting block 205 drives the wing plate 209 to move to both sides. The wing plate 209 slides smoothly under the cooperation of the guide rod 4 and the combined groove 5, and finally presents an unfolded state, greatly increasing the sealing area of the device for the seepage area. A plurality of diversion grooves 7 are opened on the outer side of the wing plate 209. A limiting cylinder 210 is fixedly connected to the outer side of the baffle 1. A rack plate 211 is slidably connected to the inner side of the limiting cylinder 210. The outer side of the rack plate 211 is meshed with the second cylindrical gear 203. Two fixing blocks 3 are fixedly connected to the outer side of the baffle 1. A guide rod 4 is fixedly connected to the outer side of the fixing block 3. A combined groove 5 is opened inside the wing plate 209. The outer side of the guide rod 4 is slidably connected to the inner wall of the combined groove 5.One end of the rack plate two 211 is provided with a positioning mechanism 6. The positioning mechanism 6 includes a mounting block 601 and a connecting frame 603. The outside of the mounting block 601 is fixedly connected to one end of the rack plate two 211. A grip rod 602 is fixedly connected to the outside of the mounting block 601. The top of the connecting frame 603 is fixedly connected to the bottom of the mounting block 601. An activity slot 604 is opened inside the connecting frame 603. A plurality of positioning holes 605 are opened on the inner wall of the activity slot 604. A T-shaped rod 606 is slidably connected to the through hole on the inner wall of the activity slot 604. A jack 607 is opened inside the T-shaped rod 606. A bolt 608 is slidably connected to the inner side of the jack 607. After the device is placed on the soft soil foundation in an area prone to water seepage, the guiding block 10 is flipped so that the guiding block 10 is in a slope state that fits the outside of the baffle 1. The slope angle is carefully designed to effectively guide the water flow and reduce the direct impact of the water flow on the device. Then, grasp the grip rod 602 and pull the entire positioning mechanism 6 downward so that the two tapered blocks 611 are inserted into the ground for positioning. At this time, the jack 607 corresponds to the lowest positioning hole 605 and is restricted by the bolt 608 to ensure that the tapered block 611 is inserted deeper into the ground. At this time, the position of the T-shaped rod 606 in the activity slot 604 is fixed, so that the tapered block 611 can be stably inserted deeper into the ground, providing reliable support for the entire device. Two connecting pieces 609 are fixedly connected to the bottom of the T-shaped rod 606. Two rotating blocks 610 are rotatably connected to the inner sides of the two connecting pieces 609. A tapered block 611 is fixedly connected to the outside of the rotating block 610. An arc-shaped block 612 is fixedly connected to the outside of the tapered block 611. The outside of the arc-shaped block 612 is attached to the outside of the T-shaped rod 606. When the T-shaped rod 606 is pulled upward, the two rotating blocks 610 rotate inside the connecting piece 609, driving the tapered block 611 to expand to both sides. The special shape of the tapered block 611, which is wide at the top and pointed at the bottom, makes it more resistant to being pulled out of the ground after it is inserted into the ground. At this time, align the hole position of the jack 607 with one of the positioning holes 605 at a higher position and lock it with the bolt 608. The L-shaped slider 613 at the bottom of the mounting block 601 slides in the corresponding slot opened on the outside of the baffle 1, further enhancing the stability of the positioning mechanism 6, so as to ensure that the overall device is not easily lifted off the ground when facing external forces such as water flow impact. Two L-shaped sliders 613 are fixedly connected to the bottom of the mounting block 601. Two guiding grooves 614 are opened on the outside of the baffle 1. A vertical rod 615 is fixedly connected to the inner side of the guiding groove 614. The inner side of the L-shaped slider 613 is slidably connected to the outside of the component Y. Two assembly grooves 8 are opened at the bottom of the baffle 1. A fixing column 9 is fixedly connected to the inside of the assembly groove 8. A connecting sleeve 11 is sleeved outside the fixing column 9. One end of the two connecting sleeves 11 is fixedly connected to the guiding block 10. The multiple diversion grooves 7 opened on the outside of the wing plate 209 cooperate with the slope of the guiding block 10 to form a unique water flow guiding structure.When the water flow impacts the device, the diversion groove 7 can disperse and guide the water flow, change the water flow direction, and enable the water flow to flow along the surfaces of the wing plate 209 and the guide block 10, reducing the direct impact force of the water flow on the baffle 1 and the wing plate 209, and effectively improving the impact resistance and service life of the device.

[0023] Specifically, first, place the device on the soft soil foundation in an area prone to water seepage. Soft soil foundations usually have loose soil and weak bearing capacity, which are high-incidence areas for water seepage problems. At this time, flip the guiding block 10 so that the guiding block 10 is in a ramp state that fits against the outer side of the baffle 1. The ramp formed by the guiding block 10 and the baffle 1 can effectively change the direction of the water flow, making the water flow smoothly along the inclination angle of the ramp, avoiding the water flow directly impacting the baffle 1 and the wing plate 209 vertically, thereby reducing the impact force of the water flow on the device, lowering the risk of damage to the device caused by water flow impact, and at the same time guiding the water flow away from the water seepage area, playing a preliminary role in preventing water seepage. Then, grasp the grip rod 602 and pull the entire positioning mechanism 6 downward so that the two tapered blocks 611 are inserted into the ground for positioning. The tapered blocks 611 are designed with a special shape that is wider at the top and narrower at the bottom. When inserting into the ground, as the depth increases, the contact area with the soil gradually becomes smaller, and the tapered blocks 611 will generate a large pressure on the soil, being able to easily penetrate the soft soil foundation and go deep underground. When the tapered blocks 611 are inserted into the ground, at this time, the insertion hole 607 corresponds to the lowest positioning hole 605, and is restricted by the pin 608. The insertion of the pin 608 firmly fixes the position of the T-shaped rod 606 in the movable slot 604, enabling the tapered blocks 611 to stably remain deep underground, like a strong anchor point, providing a strong grip and support force for the entire device, effectively preventing the device from shifting under the impact of water flow or other external forces. At the same time, since the mounting block 601 is fixedly connected to one end of the second rack plate 211, when pulling the grip rod 602 to move the positioning mechanism 6 downward, the mounting block 601 will drive the second rack plate 211 downward. The second rack plate 211 meshes with the second cylindrical gear 203. As the second rack plate 211 moves downward, according to the gear-rack transmission principle, the second cylindrical gear 203 starts to rotate. Also, because the rotating shaft 201 connects the first cylindrical gear 202 and the second cylindrical gear 203, under the driving action of the rotating shaft 201, the rotation of the second cylindrical gear 203 will drive the first cylindrical gear 202 to rotate synchronously. The first cylindrical gear 202 meshes with the two first rack plates 204, thereby causing the first rack plates 204 to slide in the sliding grooves 207. Under the guiding and limiting action of the limiting strip 206 and the limiting groove 208, the first rack plates 204 can move smoothly and precisely, and the connecting block 205 at one end drives the wing plates 209 to move to both sides, and finally the two wing plates 209 are in an unfolded state. After the wing plates 209 are unfolded, the contact area between the device and the water seepage area is greatly increased. Like an opened protective net, it can more effectively block the water seepage, significantly improving the water seepage prevention effect of the device. And the ramp of the guiding block 10 and the diversion grooves 7 on the outer side of the wing plate 209 are complementary in design. The diversion grooves 7 are evenly distributed on the outer side of the wing plate 209. When the water flow passes through the device, the ramp of the guiding block 10 first preliminarily diverts the water flow and changes the direction of the water flow. Subsequently, the water flow enters the diversion grooves 7, and the special shape and orientation of the diversion grooves 7 further disperse and guide the water flow, making the water flow flow along the surface of the wing plate 209 in a more gentle and orderly manner.This design disperses the impact force of the water flow to a larger area, greatly reducing the direct impact of the water flow on the baffle 1 and the wing plate 209, enhancing the impact resistance of the device and extending the service life of the device. In addition, when the T-shaped rod 606 is pulled upward, the rotating block 610 on the inner side of the two connecting pieces 609 will drive the conical block 611 to expand to both sides. After the conical block 611 is expanded to both sides, the contact mode with the soil changes, and the friction and bite force between it and the soil are greatly increased. Because the conical block 611 has a wide upper and pointed lower structure, it forms a stable structure similar to an inverted wedge underground after expansion, making the conical block 611 in a state that is difficult to be pulled out of the ground. At this time, align the hole position of the jack 607 with one of the positioning holes 605 located at the upper position, and lock it with the latch 608 to further fix the position of the T-shaped rod 606. The L-shaped slider 613 at the bottom of the mounting block 601 slides in the corresponding groove on the outer side of the baffle 1 to assist in positioning and enhance stability. Through this series of operations, a solid connection is formed between the entire device and the ground, as if it is rooted in the ground. It can effectively resist the impact of water flow and other external forces, ensure the stability of the entire device, and make it difficult to leave the ground.

[0024] Working principle: First, place the device on a soft soil foundation in an area prone to water seepage, flip the guide block 10 so that the guide block 10 is in a sloped state that fits the outer side of the baffle 1, then grab the handle 602 to pull the entire positioning mechanism 6 downward, so that the two conical blocks 611 are inserted into the ground for positioning. At this time, the position of the insertion hole 607 corresponding to the lowest positioning hole 605 is limited by the latch 608 to ensure that the conical block 611 is inserted deeper into the ground. At the same time, the mounting block 601 will drive the rack plate 211 to move downward, thereby rotating the cylindrical gear 203, and under the connection of the rotating shaft 201, the cylindrical gear 1 202 drives the rack plate 1 204 to move, which will make the two The wing plate 209 moves to both sides and is in an unfolded state, which can increase the blocking area, and the slope of the guide block 10 and the guide groove 7 on the outside of the wing plate 209 can reduce the direct impact of the water flow on the baffle 1 and the wing plate 209, thereby increasing the impact resistance of the device. In addition, the T-shaped rod 606 is pulled upward, and the two conical blocks 611 will unfold to both sides. The design of the conical block 611 with a wide top and a pointed bottom facilitates its insertion into the ground. The conical block 611 will also be in a state that is difficult to be pulled out of the ground. At this time, the hole position of the socket 607 is aligned with one of the upper positioning holes 605 and locked with a latch 608. This can ensure the stability of the overall device and prevent it from being impacted and leaving the ground.
