Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a diversion device for water conservancy engineering planning and its usage method. Background Technology

[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and underground water resources and the environment. They include different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways. Water conservancy project planning is a component of river basin planning or regional water conservancy planning. In water conservancy project planning, it is often necessary to use diversion devices to guide the existing water flow. For example, existing published documents CN115162277B - A diversion device for water conservancy engineering planning and CN217402030U - A diversion device for water conservancy engineering both disclose a diversion device for water conservancy engineering construction. Although the existing diversion devices can be used for diversion in water conservancy projects, they still have the following shortcomings in actual use: 1. In existing diversion devices, the pipes used for diversion are fixedly installed on the cofferdam. This means that the diversion device cannot adjust the direction of diversion according to the actual situation in actual use, resulting in poor practicality of the entire diversion device. 2. When using existing diversion devices, in order to prevent garbage, branches and other debris in the water from clogging the drainage pipes, a filter screen is installed in the cofferdam. Although the filter screen can intercept garbage, branches and other debris and prevent blockage of the pipes, the design of the filter screen means that garbage, branches and other debris will accumulate on one side of the filter screen, which will still affect the diversion of water. Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0004] In view of the fact that the existing diversion devices cannot adjust the direction of diversion according to actual needs in actual use and have poor overall practicality, a diversion device for water conservancy engineering planning is proposed.

The screw post above the slide rail groove is screwed with a locking nut.

[0006] The beneficial effects of this invention are as follows: When in use, the siphon tube can be adjusted on the baffle assembly as needed by sliding the rotating disk in the slide rail groove. This allows for adjustment of the siphon tube position according to actual requirements, facilitating the adjustment of the flow direction. After the siphon tube position is adjusted, the locking nut is rotated to fix the siphon tube on the baffle assembly via the locking assembly. This design allows for adjustment of the flow direction according to actual requirements, resulting in good overall practicality.

[0007] As a preferred embodiment of the diversion device for water conservancy engineering planning of the present invention, a plurality of external support legs are fixedly arranged in a U-shaped array at the lower end of the outer side wall of the retaining component, and a first plug hole is provided on the base plate.

[0008] As a preferred embodiment of the diversion device for water conservancy engineering planning of the present invention, the enclosure assembly includes a rectangular enclosure plate and a semi-circular arc enclosure plate. The two rectangular enclosure plates are symmetrically arranged on the opening side of the semi-circular arc enclosure plate. A first limiting strip with a vertical cross-section and a convex shape is fixed on the bottom surface of the rectangular enclosure plate along the long side direction. At the same time, a second limiting groove with an open end is opened on the top surface of the base plate for clearance fit with the first limiting strip. Both ends of the semi-circular arc enclosure plate are fixed with a second limiting strip with a horizontal cross-section and a convex shape along the vertical direction. A first limiting groove with an open upper end for clearance fit with the second limiting strip is opened on one side surface of the rectangular enclosure plate.

[0009] As a preferred embodiment of the diversion device for water conservancy engineering planning according to the present invention, a connecting plate is provided on the other side of the rectangular enclosure with a semi-circular arc enclosure, and a diversion plate is provided on the other side of the connecting plate. A second connecting strip is fixed at the upper end of one side of the connecting plate, and a second insertion hole is opened on the top surface of the other side of the connecting plate. A first insertion post is fixed on the bottom surface of the second connecting strip. A first connecting strip is fixed at the lower end of one side of the rectangular enclosure, and a first insertion hole for sliding insertion of the first insertion post is opened on the top surface of the first connecting strip. A third connecting strip is fixed at the upper end of one side of the diversion plate, and a third insertion hole is opened on the top surface of the other side of the diversion plate. A second insertion post is fixed on the bottom surface of the third connecting strip, and the second insertion post is used to slide into the second insertion hole and / or the third insertion hole.

[0010] As a preferred embodiment of the diversion device for water conservancy engineering planning of the present invention, the diversion plate is provided with vertical second insertion holes arranged in an array along the long side direction.

[0011] As a preferred embodiment of the diversion device for water conservancy engineering planning of the present invention, wherein: a telescopic sleeve is slidably sleeved on the siphon pipe located inside the retaining component, a limiting ring is fixedly provided on the outer wall of the end of the siphon pipe located inside the retaining component, the lower ends of multiple telescopic sleeves are fixedly sleeved on the same linkage plate, and the two ends of the linkage plate are symmetrically fixedly provided with suspension plates.

[0012] As a preferred embodiment of the diversion device for water conservancy engineering planning of the present invention, the distance from the end of the siphon tube located inside the enclosure component to the top surface of the base plate is h1, the distance from the end of the siphon tube located outside the enclosure component to the top surface of the base plate is h2, and the axial dimension of the telescopic sleeve is h3, then h1-h3>h2.

[0013] Given that existing filter screens used for interception still have the problem of clogging water flow in actual use, the present invention provides a further optimized and improved flow guiding device for water conservancy engineering planning, wherein: an inclined baffle plate is provided between two connecting plates, and the inclined upper end of the baffle plate is located near the baffle assembly; rotating columns that are slidably sleeved on the two connecting plates are fixed in the middle of the two side walls of the baffle plate; a gear disk is fixed on the free end of one of the rotating columns; a rack is meshed with one side of the gear disk in the vertical direction; a screw rod is rotatably connected to the upper end of the rack rod; a mating block is helically sleeved on the screw rod, and the mating block is fixedly connected to the outer wall of the connecting plate.

[0014] Another beneficial effect of the present invention is that, when the flow guiding device is in use, the baffle plate can intercept garbage, branches and other objects entering the baffle assembly.

The water flows from the lower end and below the baffle plate. The tilt angle of the baffle plate can be adjusted according to the water level by the rotation of the gear disk, so as to effectively intercept garbage, branches and other objects while ensuring the normal flow of water.

In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example

[0030] Reference Figure 1 , Figure 2 and Figure 3This is the first embodiment of the present invention. This embodiment provides a flow guiding device for water conservancy engineering planning. When the flow guiding device is in use, the flow guiding mechanism 100 is located at the water head position to block the water flow, and the drainage mechanism 200 is used to guide the water in the flow guiding mechanism 100 as needed.

[0031] Specifically, it includes a flow guiding mechanism 100, comprising a baffle assembly 101 and a base plate 102 located below the baffle assembly 101. The horizontal cross-section of the baffle assembly 101 is U-shaped. Multiple outer legs 101b are fixedly arranged in an array along the U-shaped direction at the lower end of the outer side wall of the baffle assembly 101. The arrangement of the outer legs 101b can play a supporting and limiting role on the outside of the baffle assembly 101, improving the stability during use. The base plate 102 is provided with a first pinhole 102a, thereby playing a limiting and fixing role for the base plate 102. It also includes a drainage mechanism 200, comprising a siphon pipe 201 and a locking assembly 202. Multiple siphon pipes 201 are arranged in an array and locked onto the baffle assembly 101. The siphon pipes 201 can drain the water inside the baffle assembly 101 to the outside according to the siphon principle.

[0032] See Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the locking assembly 202 includes a semi-circular clamp 202a, a screw post 202b, and a rotating disk 202c. The two semi-circular clamps 202a are symmetrically engaged on the outside of the siphon tube 201. Extended plates 202a-1 are symmetrically fixed on the two outer side walls of the open end of the semi-circular clamp 202a. A locking bolt 202a-2 is fixed on the top surface of the extended plate 202a-1 on the lower semi-circular clamp 202a. This allows for a detachable connection between the two semi-circular clamps 202a, and the two semi-circular clamps 202a can limit and fix the siphon tube 201. The top surface of the barrier assembly 101 has a vertical convex slide rail groove 101a along the long side direction. At the same time, a screw post 202b is fixed on the bottom surface of the extension piece 202a-1. The two symmetrical extension pieces 202a-1 are fixed by locking bolts 202a-2. A limiting plate 202b-1 is fixed on the bottom surface of the screw post 202b. The rotating plate 202c is fitted in the slide rail groove 101a with clearance. The top surface of the rotating plate 202c has a convex groove 202c-1 for the clearance fit of the limiting plate 202b-1. In this way, the rotating plate 202c can rotate freely relative to the limiting plate 202b-1. A locking nut 202b-2 is screwed onto the screw post 202b above the slide rail groove 101a. When the above-mentioned setup is in use, after the operator clamps and fixes the siphon tube 201 with the semi-circular clamp 202a, the operator can adjust the rotating disk 202c to move and adjust in the slide rail groove 101a as needed, so as to adjust the position of the siphon tube 201. After the adjustment is completed, the operator tightens the locking nut 202b-2 to limit and fix the screw post 202b on the barrier assembly 101. Example

[0033] Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that, in order to facilitate the disassembly, assembly and transportation of the flow guiding mechanism 100 by the staff during use, the flow guiding mechanism 100 is set to be detachable. See this embodiment for details.

[0034] Specifically, the enclosure assembly 101 includes a rectangular enclosure 101c and a semi-circular enclosure 101d. The two rectangular enclosures 101c are symmetrically arranged on the open side of the semi-circular enclosure 101d. A first limiting strip 101c-3 with a vertical convex cross-section is fixed on the bottom surface of the rectangular enclosure 101c along the long side direction. At the same time, a second limiting groove 102b with one end open is opened on the top surface of the base plate 102 for clearance fit with the first limiting strip 101c-3. This arrangement can realize a detachable fit between the rectangular enclosure 101c and the base plate 102. Both ends of the semi-circular enclosure 101d are fixed with a second limiting strip 101d-1 with a horizontal convex cross-section along the vertical direction. A first limiting groove 101c-4 with an open upper end for clearance fit with the second limiting strip 101d-1 is opened on one side surface of the rectangular enclosure 101c. This arrangement can realize a detachable fit between the semi-circular enclosure 101d and the rectangular enclosure 101c. When in use, the staff first fixes the base plate 102 in the predetermined area, then inserts the first limiting strip 101c-3 of the rectangular enclosure 101c into the second limiting groove 102b, and finally inserts the second limiting strip 101d-1 of the semi-circular enclosure 101d into the first limiting groove 101c-4, thereby realizing the cooperative installation between the enclosure assembly 101 and the base plate 102.

[0035] A connecting plate 103 is provided on one side of the rectangular enclosure 101c, which is equipped with a semi-circular enclosure 101d. A guide plate 104 is provided on the other side of the connecting plate 103. A second connecting strip 103a is fixed at the upper end of one side of the connecting plate 103, and a second insertion hole 103b is opened on the top surface of the other side of the connecting plate 103. A first insertion post 103a-1 is fixed on the bottom surface of the second connecting strip 103a. A first connecting strip 101c-1 is fixed at the lower end of one side of the rectangular enclosure 101c. 1. A first insertion hole 101c-2 for sliding insertion of a first insertion post 103a-1 is provided on the top surface of the first connecting strip 101c-1. A third connecting strip 104c-1 is fixed at the upper end of one side surface of the guide plate 104. At the same time, a third insertion hole 104b is provided on the top surface of the other side of the guide plate 104. A second insertion post 104c is fixed on the bottom surface of the third connecting strip 104c-1. The second insertion post 104c is used to slide into the second insertion hole 103b or / and the third insertion hole 104b. When the above-mentioned setup is in use, after the staff completes the installation of the baffle assembly 101, the staff inserts the first post 103a-1 on one side of the connecting plate 103 into the first insertion hole 101c-2 to realize the assembly between the connecting plate 103 and the rectangular baffle 101c. After the assembly is completed, the number of guide plates 104 is selected according to the size and shape of the water inlet of the guide area, and the second post 104c is slidably inserted into the second insertion hole 103b or / and the third insertion hole 104b to realize the cooperation between the connecting plate 103 and the guide plate 104, and the cooperation between the guide plates 104 is realized according to the number of guide plates 104.

[0036] Furthermore, the guide plate 104 has vertically arranged second brazing holes 104a arrayed along its long side direction. This arrangement can achieve fixed installation of the guide plate 104 and improve the stability of the guide plate 104. Example

[0037] Reference Figure 3 , Figure 4 and Figure 5 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in order to enable the drainage mechanism 200 to still play a good guiding role for different water levels, this embodiment is proposed.

[0038] Specifically, a telescopic sleeve 203a is slidably sleeved on the siphon pipe 201 located inside the baffle assembly 101. A limiting ring 201a is fixed on the outer wall of the end of the siphon pipe 201 located inside the baffle assembly 101. This setting can limit the position of the siphon pipe 201. The lower ends of multiple telescopic sleeves 203a are fixedly sleeved on the same linkage plate 203, and the two ends of the linkage plate 203 are symmetrically fixed with suspension plates 203b. In use, the suspension plates 203b can be used to adjust the height of the linkage plate 203 by buoyancy, thereby realizing the sliding of the telescopic sleeves 203a on the siphon pipe 201. This allows the water intake end of the siphon pipe 201 located inside the baffle assembly 101 to be adjusted according to the water level, so that the siphon pipe 201 can play a good role in drainage and flow guidance.

[0039] Furthermore, the distance from the end of the siphon tube 201 located inside the barrier assembly 101 to the top surface of the base plate 102 is h1, the distance from the end of the siphon tube 201 located outside the barrier assembly 101 to the top surface of the base plate 102 is h2, and the axial dimension of the telescopic sleeve 203a is h3. Therefore, h1 - h3 > h 2， This configuration ensures that the suction end of the siphon pipe 201 located inside the enclosure assembly 101 is always higher than the outlet end of the siphon pipe 201, so that drainage can be carried out through siphon regardless of the water level. Example

[0040] Reference Figure 2 , Figure 3 , Figure 6 , Figure 8 and Figure 9 This is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that, in order to avoid the inability to properly guide the flow due to the blockage of the drain pipe by floating objects such as garbage and branches in actual use, this embodiment is proposed.

[0041] Specifically, an inclined baffle plate 300 is provided between the two connecting plates 103, and the inclined upper end of the baffle plate 300 is located on the side close to the baffle assembly 101. Rotating columns 303a, which are slidably sleeved on the two connecting plates 103, are fixed in the middle of the two side walls of the baffle plate 300. A gear disk 303 is fixed on the free end of one of the rotating columns 303a. A rack rod 304 is meshed on one side of the gear disk 303 in the vertical direction. A screw rod 304a is rotatably connected to the upper end of the rack rod 304a. A mating block 304b is screwed onto the screw rod 304a and fixedly connected to the outer wall of the connecting plate 103. In use, the above-mentioned configuration allows the rack 304 to move along its axis by rotating the screw rod 304a in conjunction with the screw engagement of the locking block 304b. Furthermore, the meshing of the rack 304 and the gear disc 303 allows the baffle plate 300 to rotate around the rotating column 303a, thus adjusting its tilt angle to adapt to varying water levels. The baffle plate 300 can block suspended debris such as garbage and branches. Due to the flow of water, the suspended debris collects on the upper surface of the baffle plate 300, while water flows over the lower tilt of the baffle plate 300.

[0042] Furthermore, the baffle plate 300 is provided with an array of water outlet grooves 302 to achieve water discharge. The garbage accumulates on the baffle plate 300. The baffle plate 300 has a vertically L-shaped collection plate 301 fixed at its inclined upper end. The collection plate 301 can collect the suspended matter accumulated on the baffle plate 300 for subsequent centralized cleaning. Example

[0043] This embodiment is the fifth embodiment of the present invention. This embodiment provides a method for using a diversion device for water conservancy engineering planning. Specifically, it is used according to the following steps. First, insert the baffle plate into the position where the water needs to be diverted according to the direction of the water flow, so as to intercept the water flow; The equipment is used to excavate an area for placing the base plate 102 in the waterless area of ​​the interception, and the base plate 102 is fixed and limited by the chisel. Then, the barrier assembly 101 is installed on the base plate 102, and the connecting plate 103 and the dirt baffle 300 are installed on the barrier assembly 101. Assemble the guide plate 104 according to the actual situation of the guide area, and fix and limit the guide plate 104 by means of a chisel; The locking assembly 202 is fitted into the slide rail groove 101a, and the position of the locking assembly 202 is adjusted according to the direction of the required flow. Finally, the siphon tube 201 is fitted onto the locking assembly 202, and the baffle plate is removed to guide the water flow.
