Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Example 1:

[0033] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a ground structure for a coal conveying trestle bridge used in the civil engineering of thermal power plants to prevent water accumulation. The structure includes a bridge body 1. Drainage channels 12 are provided on both the left and right sides of the bottom of the bridge body 1. A fixed short plate 14 is fixedly connected to the top of the drainage channel 12. A motor 15 is fixedly connected to the top of the fixed short plate 14. A bevel gear 16 is fixedly connected to the output end of the motor 15. Turning on the motor 15 drives the bevel gear 16 to rotate. When the bevel gear 16 rotates, it meshes with a bevel gear 23 on a threaded column 18, thereby driving the threaded column 18 to rotate. Support plates 17 are fixedly connected to the front and rear sides of the bottom of the fixed short plate 14. A threaded column 18 is rotatably connected to the bottom of the support plate 17. A bevel gear 23 is fixedly connected to an adjacent end of the outer wall of the threaded column 18. The bevel gear 23 and the bevel gear... Wheel 16 meshes with the bottom of the fixed short plate 14 and is fixedly connected to multiple hollow inner sliding plates 13 at equal intervals. The outer wall of the threaded column 18 is threaded with a moving block 21. The rotation of the threaded column 18 can drive the brush 22 on the moving block 21 on the outer wall to move and clean. The left and right sides of the outer wall of the moving block 21 are fixedly connected with brushes 22. Multiple protective mechanisms 2 are installed at equal intervals on the top of the bridge body 1. The protective mechanisms 2 are used to cover the drainage channel 12 for protection. The right side of the inner wall of the bridge body 1 is fixedly connected with a hollow box 7. The hollow box 7 is slidably connected with a drawer 8 inside. The drawer 8 can facilitate the storage of tools for daily use and maintenance. The left side of the outer wall of the drawer 8 is fixedly connected with a handle 6. The handle 6 can facilitate the operation of opening or closing the drawer 8 by the staff. The outer wall of the handle 6 is fixedly connected with a protective sleeve 5.

[0034] Specifically, by turning on motor 215, the output bevel gear 16 rotates. Since bevel gear 23 and bevel gear 16 are meshed, the rotation of bevel gear 16 will drive bevel gear 23 to rotate. Bevel gear 23 is fixed to one end of the outer wall of threaded column 18. Therefore, the rotation of bevel gear 23 will cause threaded column 18 to rotate under the support of support plate 17. Because moving block 21 is threadedly connected to threaded column 18, when threaded column 18 rotates, moving block 21 will move on the outer wall of threaded column 18. Since multiple hollow inner sliding blocks 13 are equidistantly fixed to the bottom of fixed short plate 14, moving block 21 will move during the movement process. Restricted and guided by the hollow inner sliding plate 13, the brushes 22 fixedly connected to the left and right sides of the moving block 21 move together with the moving block 21 to clean the inside of the drainage channel 12, sweeping the dirt and debris in the drainage channel 12 to a suitable position for subsequent cleaning or to prevent blockage by drainage. A hollow box 7 is fixedly connected to the right side of the inner wall of the bridge body 1. A drawer 8 is slidably connected inside the hollow box 7. The drawer 8 can conveniently store tools for daily use and maintenance. A handle 6 is fixedly connected to the left side of the outer wall of the drawer 8. The handle 6 can facilitate the operation of opening or closing the drawer 8 by the staff. A protective sleeve 5 is fixedly connected to the outer wall of the handle 6.

[0035] Example 2:

[0036] Reference Figure 2 , Figure 3 and Figure 6 The protective mechanism 2 includes a fixing plate 201, which is equidistantly installed on the top of the bridge body 1. A belt 202 is fixedly connected to the top of the fixing plate 201. A hollow short block 203 is fixedly connected to the rear side of the outer wall of the fixing plate 201. A telescopic frame 204 is fixedly connected to the bottom wall of the hollow short block 203. A long short plate 208 is fixedly connected to the rear end of the belt 202. The rear end of the outer wall of the telescopic frame 204 is fixedly connected to the front side of the outer wall of the long short plate 208. A motor 207 is fixedly connected to the rear bottom of the bridge body 1. A fixed short column 206 is fixedly connected to the output short of the motor 207. A pull rope 205 is fixedly connected to the outer wall of the bridge body 1. The front end of the outer wall of the pull rope 205 is fixedly connected to the rear side of the outer wall of the long short plate 208. By turning on the motor 207, the fixed short column 206 can be rotated, thereby winding up or releasing the pull rope 205 on the outer wall. Multiple screws 3 are equidistantly threaded at the bottom of the bridge body 1. Anti-slip pads 4 are threaded on the outer wall of the screws 3. The anti-slip pads 4 can enhance the contact surface between vehicles and workers when moving on the bridge body 1 and prevent slippage. A light bulb 9 is installed on the right side of the middle of the inner wall of the bridge body 1. The light bulb 9 can play the role of auxiliary lighting in environments with poor lighting.

[0037] Specifically, by turning on the output end of the motor 207, the fixed short column 206 rotates. Since the pull rope 205 is fixedly connected to the outer wall of the fixed short column 206, and the front end of the pull rope 205 is fixedly connected to the rear side of the outer wall of the elongated short plate 208, the rotation of the fixed short column 206 will cause the pull rope 205 to wrap around the fixed short column 206, thereby pulling the elongated short plate 208 to move backward. When the elongated short plate 208 moves backward, it will drive the winding belt 202 to retract, and at the same time generate force on the telescopic frame 204. The backward pressure gradually compresses the telescopic frame 204. As the conveyor belt 202 contracts, the drainage trough 12 is gradually exposed, facilitating subsequent cleaning and maintenance. After cleaning and maintenance are completed, the motor 207 rotates in the reverse direction, and the fixed short column 206 also rotates in the reverse direction. The pull rope 205 gradually loosens, and the telescopic frame 204 begins to extend due to its own elasticity, pushing the long short plate 208 forward. The long short plate 208 drives the conveyor belt 202 to unfold forward, covering the drainage trough 12. By turning on the output end of motor 207, the fixed short column 206 rotates. Since the pull rope 205 is fixedly connected to the outer wall of the fixed short column 206, and the front end of the pull rope 205 is fixedly connected to the rear side of the outer wall of the elongated short plate 208, the rotation of the fixed short column 206 will cause the pull rope 205 to wrap around the fixed short column 206, thereby pulling the elongated short plate 208 to move backward. When the elongated short plate 208 moves backward, it will drive the winding belt 202 to retract, and at the same time, it will exert a backward force on the telescopic frame 204. The pressure causes the telescopic frame 204 to be gradually compressed. As the conveyor belt 202 contracts, the drainage trough 12 is gradually exposed, facilitating subsequent cleaning and maintenance. After cleaning and maintenance are completed, the motor 207 rotates in the opposite direction, and the fixed short column 206 also rotates in the opposite direction. The pull rope 205 gradually loosens, and the telescopic frame 204 begins to extend due to its own elasticity, pushing the long short plate 208 forward. The long short plate 208 drives the conveyor belt 202 to unfold forward, covering the drainage trough 12.

[0038] Example 3:

[0039] Reference Figure 1 , Figure 2 and Figure 3 The inner wall of the bridge body 1 is threaded with screw 2 10 on the left side, and screw 2 10 is threaded with hook 11 on the outer wall. Hook 11 can be used to hang tools for daily use and cleaning for subsequent use. The outer wall of motor 2 15 is fixedly connected with support feet 19 on both the left and right sides. Support feet 19 can reinforce motor 2 15 and prevent motor 2 15 from shifting and being damaged. Screw 3 20 is threaded with the outer wall of support foot 19.

[0040] Specifically, screw 10 is threadedly connected to the left side of the inner wall of bridge body 1, and hook 11 is threadedly connected to the outer wall of screw 10. Hook 11 can be used to hang tools for daily use and cleaning for subsequent use. Support legs 19 are fixedly connected to the left and right sides of the outer wall of motor 15. Support legs 19 can reinforce motor 15 and prevent motor 15 from shifting and being damaged. Screw 20 is threadedly connected to the left side of the outer wall of support leg 19.

[0041] Working principle: By turning on motor 215, the output bevel gear 16 rotates. Since bevel gear 23 and bevel gear 16 are meshed, the rotation of bevel gear 16 will drive bevel gear 23 to rotate. Bevel gear 23 is fixed to one end of the outer wall of threaded column 18. Therefore, the rotation of bevel gear 23 will cause threaded column 18 to rotate under the support of support plate 17. Because moving block 21 is threadedly connected to threaded column 18, when threaded column 18 rotates, moving block 21 will move on the outer wall of threaded column 18. Furthermore, because multiple hollow parts are equidistantly fixed at the bottom of fixed short plate 14... During the movement of the inner sliding plate 13 and the moving block 21, the inner sliding plate 13 restricts and guides the movement. The brushes 22 fixedly connected to the left and right sides of the moving block 21 move together with the moving block 21 to clean the inside of the drainage channel 12. This cleans the dirt and debris in the drainage channel 12 to a suitable position for subsequent cleaning or to prevent blockage by drainage. This avoids the problem that the drainage channel 12 of the bridge body 1 will gradually accumulate and adhere to the drainage channel 12 after a long period of rainwater and impurities flow and discharge, which would cause blockage of the drainage channel 12 and cause inconvenience to subsequent drainage and waterproofing work.

[0042] By rotating the fixed short column 206 at the output end of motor 207, the pull rope 205 is fixedly connected to the outer wall of the fixed short column 206, and the front end of the pull rope 205 is fixedly connected to the rear side of the outer wall of the elongated short plate 208. Therefore, the rotation of the fixed short column 206 will cause the pull rope 205 to wrap around the fixed short column 206, thereby pulling the elongated short plate 208 backward. When the elongated short plate 208 moves backward, it will drive the winding belt 202 to retract, and at the same time exert backward pressure on the telescopic frame 204, causing the telescopic frame 204 to gradually... As the conveyor belt 202 contracts, the drainage trough 12 is gradually exposed, facilitating subsequent cleaning and maintenance. After cleaning and maintenance are completed, the motor 207 rotates in the opposite direction, and the fixed short column 206 also rotates in the opposite direction. The pull rope 205 gradually loosens, and the telescopic frame 204 begins to extend due to its own elasticity, pushing the long short plate 208 forward. The long short plate 208 drives the conveyor belt 202 to unfold forward, covering the drainage trough 12, thereby achieving the function of covering the drainage trough 12 for protection.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
