[0002] In current water conservancy projects, sluice gates are important structures for controlling water flow, and their sealing performance directly affects the overall effect of the project. However, the sealing performance of existing sluice gate structures will gradually decrease during long-term use due to material aging, water erosion, and other reasons.

[0003] A search revealed a Chinese patent publication number of CN215948110U, which discloses a highly sealed sluice gate for water conservancy projects. The sluice gate comprises a base plate with side plates symmetrically welded vertically to the left and right ends of the upper surface of the base plate. A mounting groove is provided in the middle of the upper surface of the base plate. The two side plates are symmetrically provided with limiting chutes on opposite sides. A top plate is welded horizontally to the top ends of the two side plates. A transmission mechanism is provided on the top plate, and a gate is provided at the bottom end of the transmission mechanism. The left and right sides of the gate are connected to the two limiting chutes by a first sealing mechanism, respectively. The bottom of the gate is connected to the mounting groove by a second sealing mechanism, and the left and right corners of the gate bottom are connected to the left and right ends of the mounting groove by a third sealing mechanism. While ensuring high sealing performance, the utility model also effectively reduces wear between the first and second rubber strips between the gate and the side plates, thereby improving sealing performance and extending service life. However, in actual use, the rubber sealing strips used are easily damaged after long-term use, affecting the sealing effect.

[0038] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Refer to the attached Figure 1 , Attachment Figure 3 and attached Figure 4 The utility model provides an embodiment: a river sluice sealing structure, including a base 1, a pillar 3 is fixedly connected to the top of the base 1, a slide groove 4 is provided on the adjacent side of the pillar 3 and the base 1, the inner sides of multiple slide grooves 4 are slidably connected with the same slider 6, the outer wall of the slider 6 is fixedly connected with a gate plate 5, the outer wall of the slider 6 is provided with a sealing strip 7, the left and right sides of the outer wall of the slider 6 are slidably connected with multiple moving columns 8, the adjacent sides of the multiple moving columns 8 are fixedly connected with a spring 9, the adjacent sides of the multiple springs 9 are fixedly connected with a triangular plate 10, the inner sides of the multiple sealing strips 7 are fixedly connected with multiple connecting columns 12, the multiple connecting columns 12 are fixedly connected to the inner sides of the multiple connecting columns 12. One end is fixedly connected to a triangular slide 11, which is arranged on the outside of the triangular plate 10. The outer walls of the triangular plate 10 and the connecting column 12 are slidably connected to the inner side of the slider 6, and the outer wall of the slider 6 is provided with a fastening mechanism 2; the outer walls of the multiple movable columns 8 and the connecting column 12 are fixedly connected to the outer walls of the multiple sealing rings 13, and the outer walls of the multiple sealing rings 13 are slidably connected to the outer wall of the slider 6; the outer walls of the multiple sealing strips 7 are fixedly connected to the wear-resistant layer 18, and the outer wall of the wear-resistant layer 18 is made of ceramic particles and a polymer matrix; the sealing strip 7 is made of a polymer composite material, the gate 5 is made of a corrosion-resistant alloy material, and the outer wall of the gate 5 is provided with a grid 19;

[0040] Specifically, through the synergistic effect of the movable column 8, spring 9, triangular support plate 10, triangular slide plate 11 and connecting column 12 that are slidably connected to the left and right sides of the outer wall of the slider 6, when water flows through, the sealing strip 7 can automatically stretch outward and press more tightly against the slide groove 4 to achieve adaptive sealing reinforcement. The outer walls of multiple movable columns 8 and connecting columns 12 are fixedly connected with sealing rings 13, which enhances the sealing of the internal structure of the slider 6 and prevents the invasion of water flow and impurities. The outer walls of multiple sealing strips 7 are provided with a wear-resistant layer 18 made of ceramic particles and polymer matrix to improve the wear resistance of the sealing strip 7. The sealing strip 7 is made of a polymer composite material, and the gate plate 5 is made of a corrosion-resistant alloy material. A grid 19 is opened on the outer wall of the gate plate 5 to enhance the overall durability.

[0041] Refer to the attached Figure 5 The fastening mechanism 2 includes a plurality of dovetail plates 201, each of which is fixedly connected to the outer wall of the slider 6. A dovetail groove 202 is provided on the inner side of the sealing strip 7. The outer walls of the dovetail plates 201 are slidably connected to the inner side of the dovetail groove 202. The slider 6 and the sealing strip 7 are connected by a special adhesive 203.

[0042] Specifically, the cooperation between the dovetail plate 201 and the dovetail groove 202 can achieve precise positioning when installing the sealing strip 7, effectively prevent the sealing strip 7 from moving and dislocating in the horizontal direction, and ensure the accuracy of the installation position of the sealing strip 7. The sliding connection method of the dovetail structure increases the contact area, improves the connection strength between the slider 6 and the sealing strip 7, and enables the sealing strip 7 to withstand greater external forces and is not easy to fall off. The slider 6 and the sealing strip 7 are further connected by a special adhesive 203, forming a double fixation with the dovetail structure, which greatly enhances the reliability of the seal and maintains good sealing performance even under long-term use and harsh environments.

[0043] Refer to the attached Figure 2 The top of the pillar 3 is fixedly connected to a hydraulic pump 14, and one end of the hydraulic pump 14 is fixedly connected to a push rod 15; the top of the gate 5 is fixedly connected to a connecting ring 16, and the top of the connecting ring 16 is fixedly connected to the bottom of the push rod 15; the top of the pillar 3 is fixedly connected to a support frame 17, and the top of the support frame 17 is fixedly connected to the bottom of the hydraulic pump 14;

[0044] Specifically, the hydraulic pump 14 is connected to the connecting ring 16 at the top of the gate plate 5 through the push rod 15, which can accurately control the lifting and lowering of the gate plate 5. The support frame 17 at the top of the pillar 3 provides stable support for the hydraulic pump 14, ensuring that the hydraulic pump 14 will not shake or shift during operation, thereby ensuring the stability and reliability of pushing the gate plate 5 up and down.

[0045] Working principle: The slide groove 4 opened by the base 1 and the support 3 provides a track for the sliding of the slider 6. When sealing is required, the hydraulic pump 14 is started to push the push rod 15 to move downward with the gate plate 5 to resist the passage of water. When the water flows in time, the impact force of the water flow acts on the gate plate 5. At this time, the moving columns 8 slidingly connected to the left and right sides of the outer wall of the slider 6 move inward under the pressure of the water flow. While the moving columns 8 move inward, the spring 9 is compressed, thereby causing the triangular support plate 10 fixedly connected to the other side of the spring 9 to move forward. Due to the contact between the triangular support plate 10 and the triangular slide plate 11, the forward movement of the triangular support plate 10 causes the triangular slide plate 11 set on one side to move outward, and the triangular slide plate 11 moves outward with The connecting column 12 fixedly connected thereto moves outward. When the connecting column 12 moves outward, the sealing strip 7 is stretched outward due to its fixed connection with the sealing strip 7. After the sealing strip 7 is stretched outward, it presses more tightly against the slide groove 4, maintaining good sealing. When installing the sealing strip 7 on the slider 6, the dovetail plate 201 on the slider 6 is first inserted into the dovetail groove 202 provided on the inner side of the sealing strip 7. The matching structure of the dovetail plate 201 and the dovetail groove 202 can provide preliminary positioning and fixation, preventing the sealing strip 7 from moving and misaligning in the horizontal direction. Then, a special adhesive 203 is applied between the slider 6 and the sealing strip 7 to further enhance the connection strength between the two. The special adhesive 203 can fill the small gap between the dovetail plate 201 and the dovetail groove 202, as well as other contact areas of the slider 6 and the sealing strip 7, thereby achieving a more secure connection.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
