[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering. Only by building water conservancy projects can water flow be controlled, floods be prevented, and water volume be regulated and distributed to meet the water needs of people's lives and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, ferries, and fishways.

[0003] Currently, water conservancy dredging trenches on the market require the ground soil to be crushed during excavation to facilitate soil removal. The trench excavation depth is usually fixed, making it difficult to conveniently adjust the trench structure according to the excavation needs. Furthermore, the trenching tooth structure is prone to damage, breakage, or loosening during the excavation process, making it difficult to easily install, fix, disassemble, or replace the trenching teeth, thus affecting the efficiency and practicality of the trenching operation. Therefore, it is necessary to design a trench excavation device for water conservancy and hydropower construction to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figure 1-7As shown, this utility model provides a trench excavation device for water conservancy and hydropower construction, including a mobile frame 1. A driving component for driving the excavating component is fixedly installed on the top of the mobile frame 1. An adjusting component for adjusting the trenching depth of the excavating component is installed on one side of the mobile frame 1. The excavating component also includes a rotating disk 101 for driving the trenching teeth 2 to rotate rapidly. Multiple trenching teeth 2 are arranged in a staggered manner on both sides of the rotating disk 101. Multiple fixed frames 3 arranged in a circular pattern are welded on both sides of the rotating disk 101. A locking component for fixing the trenching teeth 2 is installed on one side of the fixed frame 3. A protective shell 29 is installed on the other side of the support shell 15 by bolts. A material guide shell 30 is installed on one side of the protective shell 29 by bolts.

[0025] In addition, the driving component can drive the two sets of multiple trenching teeth 2 on the edge of the rotating disk 101 to rotate rapidly, so that the trenching teeth 2 can excavate the trench. The adjusting component can adjust the depth of the trenching teeth 2 so as to adjust the depth according to the needs of the trench. The locking component can lock and fix the trenching teeth 2 so as to disassemble and replace or install the trenching teeth 2. The protective shell 29 can block and protect the broken soil, and the material guide shell 30 can discharge the material.

[0026] Specifically, the drive unit is fixedly mounted on a fixed plate 4 on one side of the moving frame 1. An engine 5 is mounted on the top of the fixed plate 4. A drive disc 6 is mounted on the outside of the engine 5 through the output shaft. A fixed housing 7 is fixedly mounted on one side of the drive disc 6. A connecting shaft 8 passes through the inside of the fixed housing 7. A driven disc 9 is fixedly mounted on one end of the connecting shaft 8. Two belts 10 are mounted on the outside of the drive disc 6 and the driven disc 9. The drive unit also includes a first sprocket 11 mounted inside the fixed housing 7 and located at the other end of the connecting shaft 8. A second sprocket 12 is mounted inside the fixed housing 7 and near the other end. A chain 13 is mounted on the outside of the first sprocket 11 and the second sprocket 12. A rotating shaft 14 is fixedly mounted inside the second sprocket 12. The rotating shaft 14 is used to install and fix the drive disc 6.

[0027] Among them, the engine 5 is a diesel engine 5 or a gasoline engine 5. The engine 5 drives the driven plate 9 to rotate through the two belts 10 on the outer side of the drive plate 6. The driven plate 9 drives the first sprocket 11 on the outer side of the connecting shaft 8 to rotate. The first sprocket 11 drives the second sprocket 12 to rotate through the chain 13. Therefore, the second sprocket 12 drives the drive plate 6 to rotate rapidly through the rotating shaft 14, so that the rotating plate 101 drives multiple trenching teeth 2 to rotate rapidly to perform trenching operations.

[0028] More specifically, the adjusting component includes a support shell 15 mounted on one side of the fixed plate 4 and the outside of the driven disc 9. Two connecting plates 16 are hinged between the support shell 15 and the fixed plate 4. A connecting rod 17 is hinged to one end of the support shell 15, and a connecting frame 18 is hinged to one end of the connecting rod 17. A support frame 19 is fixedly mounted on the top of the movable frame 1. A lead screw 20 is screwed to the inner side of the support frame 19 near one end. A pushing part 201 is fixedly mounted on the outer side of the lead screw 20 near one end. The connecting frame 18 is slidably connected to the support frame 19. A handle 21 is fixedly mounted on one end of the lead screw 20.

[0029] It should be added that the lead screw 20 can drive the connecting frame 18 to slide telescopically outside the support frame 19. Then, the connecting frame 18 is driven to rotate hingedly through the connecting rod 17. At the same time, the two connecting plates 16 support the support shell 15. The support shell 15 rotates around the output shaft inside the drive disk 6. At the same time, the support shell 15 drives the drive disk 6 to change angle, so that the drive disk 6 can move downward for depth adjustment.

[0030] Furthermore, the locking component includes a screw 22 that runs through one side of the fixed frame 3. A drive plate 24 is installed on the outside of the screw 22 near one end through the fixed part 23. Locking pins 25 are fixedly connected to one side of the drive plate 24 near both ends. Two locking slots 26 are opened on one side of the trenching teeth 2. A lock nut 27 is screwed onto one end of the screw 22. Multiple circumferentially arranged limit blocks 28 are fixedly connected to both sides of the rotating disk and on one side of the fixed frame 3. The limit blocks 28 are embedded in one side of the trenching teeth 2.

[0031] The screw 22 can be screwed to the fixing frame 3. The screw 22 can drive the two locking posts 25 on one side of the driving plate 24 to move through the fixing part 23, so that the locking posts 25 can be inserted into or disengaged from the locking groove 26. The limiting block 28 is embedded in one side of the trenching tooth 2 for positioning. The anti-reverse nut 27 is screwed to one end of the screw 22 to prevent the screw 22 from loosening or disengaging, thereby improving the convenience and stability of installing the trenching tooth 2.

[0032] Working principle: First, the moving frame 1 is moved, then the engine 5 is started, causing the driven plate 9 to rotate via the two belts 10 on the outer side of the drive plate 6. At this time, the driven plate 9 drives the first sprocket 11 on the outer side of the connecting shaft 8 to rotate. Simultaneously, the first sprocket 11 drives the second sprocket 12 to rotate via the chain 13. The second sprocket 12 then drives the grooved teeth 2 on the outer side of the drive plate 6 to rotate rapidly via the rotating shaft 14. Then, the handle 21 is turned, causing the lead screw 20 to rotate. The lead screw 20 then drives the connecting frame 18 to slide upward on the outer side of the support frame 19 via the pushing part 201. Then, the connecting frame 18 is hinged and rotated via the connecting rod 17. At the same time, the two connecting plates 16 support the support shell 15. The support shell 15 rotates around the output shaft inside the drive plate 6. Simultaneously, the support shell 15 causes the rotating plate 101 to change angle, so that the rotating plate 101 can move downward for depth adjustment.
