Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a river hazard removal sluice reinforcement device. Background Art

[0002] The river sluice gate is an important water conservancy project facility used to regulate the water volume of rivers, control floods, and ensure the safety of rivers. The sluice gate regulates the water flow between upstream and downstream by opening or closing the gate, which can prevent floods and ensure sufficient water supply in the dry season.

[0003] The reinforcement of river sluice gates is to improve their safety, stability and service life, and to ensure their normal operation under various hydrological conditions, especially to play an effective role in extreme weather and flood events. Therefore, the reinforcement of river sluice gates is indispensable. Existing river sluice gates are usually reinforced by welding multiple reinforcing pipes on the gates in an interlaced manner. This reinforcement method can only enhance the gate's own resistance to impact and extrusion, but cannot enhance the connection strength between the sluice gate and the side of the river. When the sluice gate is subjected to the lateral impact force of a large flow of water, there is a phenomenon that the bottom of the gate is subjected to greater pressure and deformation, thereby affecting the sealing of the gate and reducing the effectiveness of the use of the sluice gate.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] See also Figure 1 , Figure 3 and Figure 4 A river channel sluice reinforcement device comprises a positioning frame 1, wherein the positioning frame 1 is a U-shaped structure with an opening facing downward, and sliding grooves 11 are provided at opposite ends of two vertical sections of the positioning frame 1.

[0034] In specific operation, before use, the positioning frame 1 is first hoisted to the position where the sluice gate is to be installed in the river channel by using existing hoisting equipment, and then the positioning frame 1 is opened downward and fixed at the installation position by cement.

[0035] See also Figure 1 , Figure 2 , Figure 5 and Figure 8 The river channel hazard removal and sluice reinforcement equipment also includes a door panel device 2, which is connected to the two sliding grooves 11, and the door panel device 2 includes a rectangular plate 21 that is slidably connected to the two sliding grooves 11 at the same time.

[0036] See also Figure 1 , Figure 5 and Figure 8 The river channel hazard removal and sluice reinforcement equipment also includes a lifting device 3, which is connected to the horizontal section of the positioning frame 1. The lifting device 3 includes a threaded rod 31 connected to the horizontal section of the positioning frame 1, a circular plate 32 is installed at the lower end of the threaded rod 31, a clamping joint 33 is installed in the middle of the lower end of the circular plate 32, and a lifting mechanism 34 is connected to the circular plate 32. The lifting device 3 also includes two strip plates 35 fixedly connected to the front and rear ends of the horizontal section of the positioning frame 1 respectively, and a driving module 36 is installed on the horizontal section of the positioning frame 1, and the driving module 36 is threadedly connected to the threaded rod 31.

[0037] During specific operation, the driving module 36 is an existing screw-type gate opening and closing machine. Before use, the driving module 36 is connected to the existing power supply and started. The driving module 36 drives the threaded rod 31 to rotate and move the threaded rod 31 downward. The threaded rod 31 drives the lifting mechanism 34 to descend by driving the circular plate 32. At the same time, the rectangular plate 21 slides downward in the two sliding grooves 11 by its own gravity until the bottom wall of the river channel at the lower end of the rectangular plate 21 contacts.

[0038] See also Figure 5 and Figure 8A rectangular cavity 22 is provided inside the rectangular plate 21, and a V-shaped bar 23 with its opening facing downward is installed in the rectangular cavity 22. The lower ends of the two inclined sections of the V-shaped bar 23 are connected to bottom connection mechanisms 25, and a pushing mechanism 24 connected to the inclined sections of the V-shaped bar 23 is provided above the bottom connection mechanism 25. The inner end surface of the bottom wall of the rectangular plate 21 is symmetrically provided with limiting grooves 26.

[0039] See also Figure 1 , Figure 5 and Figure 8 The pushing mechanism 24 includes a pushing rod 241 which is slidably connected to the inclined section of the V-shaped bar 23 and is in a vertical state. A pushing block 242 with a right-angled trapezoidal structure is installed on the upper end of the pushing rod 241. The inclined surface of the pushing block 242 cooperates with the V-shaped bar 23, and a slope is arranged at the lower end of the pushing block 242.

[0040] See also Figure 1 and Figure 5 The lifting mechanism 34 is connected to the two pushing blocks 242 at the same time. The lifting mechanism 34 includes a circular frame 341 rotatably connected to the annular surface of the circular plate 32. The cross-section of the circular frame 341 is a U-shaped structure with an opening facing inward. The upper and lower circular segments of the circular frame 341 are rotatably connected to the opposite ends with multiple circumferentially evenly distributed balls 343. The lower end of the circular frame 341 is symmetrically installed with lifting rods 342. The lower end of the lifting rod 342 slides through the top wall of the rectangular plate 21 and is fixedly connected to the corresponding upper end of the pushing block 242.

[0041] During specific operation, at the beginning, the upper end of the pushing block 242 is tightly attached to the top wall of the rectangular plate 21 and supports and limits the rectangular plate 21. During the downward movement of the threaded rod 31, the threaded rod 31 drives the annular frame 341 to move downward through the circular plate 32, and the annular frame 341 drives the two pushing blocks 242 to move downward through the two lifting rods 342. During this process, the rectangular plate 21 is always tightly attached to the upper end of the pushing block 242 and descends along with the pushing block 242 through its own gravity until the lower end of the rectangular plate 21 contacts the bottom wall of the river channel. After that, the threaded rod 31 continues to move downward, and the threaded rod 31 drives the annular frame 341 to continue to move downward through the circular plate 32. The annular frame 341 drives the two pushing blocks 242 to move downward through the two lifting rods 342 and separate from the top wall of the rectangular plate 21, and the two pushing blocks 242 drive the two pushing rods 241 to move downward.

[0042] See also Figure 5 A semi-cylindrical protrusion is integrally formed at the lower end of the pushing rod 241 , and a rectangular opening 2411 is opened in the middle of the lower end of the pushing rod 241 .

[0043] See also Figure 5 and Figure 6The bottom connection mechanism 25 includes a rectangular through hole 251 opened at the lower end of the vertical side wall of the rectangular plate 21, and a bottom connection plate 252 is slidably connected in the rectangular through hole 251. The bottom connection plate 252 is slidably connected with the inclined section of the V-shaped bar 23. The upper end of the bottom connection plate 252 is integrally formed with a guide protrusion 253 located on the inner side of the V-shaped bar 23. The end of the bottom connection plate 252 away from the guide protrusion 253 is provided with a first drainage through hole 257. A first sealing sleeve 256 is installed on the surface of the bottom connection plate 252, and the first sealing sleeve 256 is fixedly connected to the inner end surface of the vertical side wall corresponding to the rectangular plate 21.

[0044] See also Figure 5 and Figure 6 A rectangular frame 12 is installed at the opposite ends of the two vertical sections of the positioning frame 1, and the rectangular frame 12 is plugged into and matched with the bottom connecting plate 252.

[0045] During specific operation, initially, one end of the bottom plate 252 away from the guide protrusion 253 is located in the rectangular through hole 251. When the pushing block 242 moves downward, the semi-cylindrical protrusion at the lower end of the pushing rod 241 pushes the guide protrusion 253 on the rectangular through hole 251. The guide protrusion 253 is driven by the force to slide the bottom plate 252 in the inclined section of the V-shaped bar 23 and the rectangular through hole 251 until the end of the bottom plate 252 moves into the rectangular frame 12. The rectangular frame 12 is longitudinally aligned with the bottom plate 252. The bottom plate 252 is limited in position, thereby increasing the connection strength between the bottom of the rectangular plate 21 and the positioning frame 1, and improving the strength of the bottom of the rectangular plate 21 against lateral impact and compression of water flow. The first drainage hole 257 is a T-shaped structure. When the end of the bottom connecting plate 252 moves to the rectangular frame 12, the water in the rectangular frame 12 is squeezed into the first drainage hole 257 and discharged, thereby preventing the water from affecting the cooperation between the bottom connecting plate 252 and the rectangular frame 12. The first sealing sleeve 256 can effectively prevent water from entering the rectangular cavity 22.

[0046] When the end of the bottom connecting plate 252 is inserted into the rectangular frame 12, the two pushing rods 241 continue to move downward and are inserted into the corresponding limiting grooves 26, and then the driving module 36 is closed, and the limiting grooves 26 cooperate with the pushing rods 241 to realize the function of limiting the pushing rods 241. At the same time, the two pushing rods 241 cooperate with the V-shaped bars 23 to form a stable structure of multiple triangles, which further enhances the overall impact and compression resistance of the rectangular plate 21.

[0047] See also Figure 1 , Figure 5 and Figure 6 The door panel device 2 further comprises a cylindrical rod 27 mounted on the upper end of the rectangular plate 21 , and a clamping groove 28 is formed on the upper end of the cylindrical rod 27 .

[0048] During specific operation, while the two pushing rods 241 continue to move downward and insert into the corresponding limit grooves 26, the threaded rod 31 drives the clamping joint 33 through the circular plate 32 to insert into the clamping groove 28 at the upper end of the cylindrical rod 27, thereby realizing the overall connection between the threaded rod 31 and the rectangular plate 21, and further increasing the support points of the rectangular plate 21.

[0049] See also Figure 2 , Figure 5 and Figure 7 A plurality of circular through holes 29 evenly distributed from top to bottom are formed on the left and right side walls of the rectangular plate 21 , and the plug-in mechanism 20 is connected in the circular through holes 29 .

[0050] See also Figure 2 , Figure 5 , Figure 7 and Figure 8 The plug-in mechanism 20 includes a plug-in rod 201 that is slidably connected to the circular through hole 29, and a circular plate 202 located in the rectangular cavity 22 is installed on the annular surface of the plug-in rod 201. A second sealing sleeve 203 sleeved on the outer periphery of the plug-in rod 201 is installed between the circular plate 202 and the inner end surface of the vertical side wall corresponding to the rectangular plate 21. A return spring 204 is sleeved on the outer periphery of the second sealing sleeve 203, and the two ends of the return spring 204 are respectively fixedly connected to the circular plate 202 and the inner end surface of the vertical side wall corresponding to the rectangular plate 21. A semi-spherical protrusion is integrally formed at one end of the plug-in rod 201 located in the rectangular cavity 22, and a plurality of sliding beads 205 evenly distributed in the circumferential direction are rotatably connected in the circular through hole 29. A second drainage through hole 206 is opened at one end of the plug-in rod 201 away from the circular plate 202.

[0051] See also Figure 5 and Figure 7 A plurality of cylindrical frames 13 evenly distributed from top to bottom are installed at the opposite ends of the two vertical sections of the positioning frame 1 , and the cylindrical frames 13 are plugged and matched with the corresponding plug-in rods 201 .

[0052] During specific operation, while the pushing block 242 moves downward, the slope on the pushing block 242 pushes the semi-spherical protrusions in the multiple plug-in rods 201 on the same side in turn, and the plug-in rod 201 slides in the circular through hole 29 under force, and the end of the plug-in rod 201 moves to the corresponding cylindrical frame 13, and the cylindrical frame 13 limits the longitudinal position of the plug-in rod 201, which further strengthens the impact and compression resistance of the rectangular plate 21. After the pushing block 242 squeezes and pushes the multiple plug-in rods 201, the inclined section of the V-shaped bar 23 and the pushing block The inclined surface of 242 is in close contact, and the pushing block 242 continuously blocks and limits the multiple plug-in rods 201. The plug-in rod 201 squeezes the return spring 204 through the annular plate 202 while moving, and the sliding bead 205 reduces the friction between the plug-in rod 201 and the circular through hole 29. The second sealing sleeve 203 can effectively prevent water from entering the rectangular cavity 22. The second drainage through hole 206 plays a function of draining water in the cylindrical frame 13 when the end of the plug-in rod 201 moves to the corresponding cylindrical frame 13 (such as Fig. 9 shown).

[0053] See also Figure 5 and Figure 8 The bottom connection mechanism 25 also includes a rotating roller 254 which is arranged on a side of the bottom connection plate 252 away from the rectangular through hole 251 and is rotatably connected to the inner end surface of the bottom wall of the rectangular plate 21 through a roller frame. A traction rope 255 is installed at one end of the bottom connection plate 252 away from the rectangular through hole 251, and the top wall of the rectangular opening 2411 is fixedly connected to the traction rope 255.

[0054] In the specific operation, during the gate opening process, the driving module 36 drives the threaded rod 31 to rise, the threaded rod 31 drives the circular frame 341 to rise through the circular plate 32, the circular frame 341 drives the pushing block 242 to rise through the two lifting rods 342, the pushing block 242 drives the pushing rod 241 to rise, the pushing rod 241 drives the traction rope 255 to move through the rectangular opening 2411, the traction rope 255 gradually straightens and drives the bottom connecting plate 252 to move, and the bottom connecting plate 252 moves from the rectangular frame 12, thereby The limit on the bottom of the rectangular plate 21 is released, and at the same time, the pushing block 242 is gradually separated from the multiple plug-in rods 201, the squeezed reset spring 204 is reset and drives the plug-in rod 201 to separate from the cylindrical frame 13 through the annular plate 202, thereby releasing the limit on the lifting direction of the rectangular plate 21, and then the pushing block 242 continues to rise and contacts the top wall of the rectangular plate 21. The two pushing blocks 242 that continue to rise drive the rectangular plate 21 to slide upward in the two sliding grooves 11, thereby realizing the opening of the sluice gate, and the work is completed.
