Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water-stopping device for water conservancy engineering construction. Background Technology

[0002] Water conservancy projects are a collective term for projects (including new construction, expansion, reconstruction, reinforcement, and repair) and their supporting and ancillary projects, such as flood control, drainage, irrigation, power generation, water supply, reclamation, soil and water conservation, resettlement, and water resource protection. They are projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water-stopping devices are an important component of water conservancy projects. Water-stopping devices, also known as gates, are control facilities used to close and open water discharge channels. They can be used to intercept water flow, control water level, regulate flow, and discharge sediment and floating debris.

[0003] Currently, most sluice gates have sealing grooves at the bottom and sides to ensure sealing. When the gate is open, sludge and mortar in the flowing water will enter the inner side of the sealing groove. Over time, the sludge and mortar in the sealing groove will accumulate, thus affecting the sealing performance of the gate when closed and the water-stopping effect of the gate. Therefore, a water-stopping device for water conservancy engineering construction is proposed to address the above problems. Utility Model Content

[0023] Example

[0024] like Figure 1-4As shown, a water-stopping device for water conservancy construction includes a gate frame 1 and a motor 2. The top of the gate frame 1 is fixedly connected to the motor 2, and the end of the main shaft of the motor 2 is fixedly connected to a screw 3. A gate 4 is screwed to the outside of the screw 3. A sealing groove 6 is provided on the inner side of the gate frame 1, and the gate 4 is slidably connected to the gate frame 1 through the sealing groove 6. A fixing plate 5 is fixedly connected to one end of the gate frame 1, and the fixing plate 5 is slidably connected to the gate 4. An adjustment mechanism is provided at one end of the fixing plate 5. A connecting block 14 is fixedly connected to one end of the adjustment mechanism. A fixing rod 15 is fixedly connected to one end of the connecting block 14. A protective mechanism is fixedly connected to one end of the fixing rod 15.

[0025] As a further improvement to this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the protective mechanism includes a connecting frame 16 fixedly connected to the fixed rod 15. One end of the connecting frame 16 is fixedly connected to a side protection plate 17 and a lower protection plate 18, so that the connecting frame 16, the side protection plate 17 and the lower protection plate 18 can seal and protect the side and bottom of the sealing groove 6, thereby preventing sludge and mortar from entering the inner side of the sealing groove 6, ensuring the sealing between the gate 4 and the sealing groove 6, and improving the water-stopping effect of the gate 4.

[0026] As a further improvement to this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, there are two side protection plates 17, which are symmetrically distributed on both sides of the vertical center line of the connecting frame 16. The two side protection plates 17 can seal and protect both sides of the sealing groove 6.

[0027] As a further improvement to this utility model, such as Figure 4As shown, the adjusting mechanism includes a fixing block 7 fixedly connected to a fixing plate 5. A first rotating shaft 8 is rotatably connected to the inner side of the fixing block 7. Worms 10 are fixedly connected to both ends of the first rotating shaft 8. A handwheel 9 is fixedly connected to one end of one of the worm gears 10. A connecting plate 11 is rotatably connected to the outer side of the first rotating shaft 8, and the connecting plate 11 is fixedly connected to the fixing plate 5. A second rotating shaft 13 is rotatably connected to one end of the connecting plate 11. A worm gear 12 is fixedly connected to the outer side of the second rotating shaft 13, and the worm gear 12 is fixedly connected to... The worm gear 10 is engaged, and the worm wheel 12 is fixedly connected to the connecting block 14. When the gate 4 is open, if the sealing groove 6 needs to be protected by the side protection plate 17 and the lower protection plate 18, the operator first pulls the locking screw 20 out from the inside of the worm gear 10. Then, the operator rotates the worm gear 10 by using the handwheel 9, which causes the worm gear 10 to rotate with the worm wheel 12. Then, the worm wheel 12, through the connecting block 14, the fixing rod 15, and the connecting frame 16, uses the side protection plate 17 and the lower protection plate 18 to cover the sealing groove 6.

[0028] As a further improvement to this utility model, such as Figure 3 As shown, a protective cover 19 is provided on the outer side of the worm gear 10 and the worm wheel 12, and the edge of the protective cover 19 is fixedly connected to the fixing plate 5, the connecting plate 11 and the fixing rod 15. The protective cover 19 is made of rubber.

[0029] As a further improvement to this utility model, such as Figure 3 As shown, a locking screw 20 is helically connected to the inner side of one of the worm gears 10. The locking screw 20 is helically connected to the gate frame 1. When the side protection plate 17 and the lower protection plate 18 are adjusted to the appropriate position, the locking screw 20 is used to limit and fix the worm gear 10 and the gate frame 1, ensuring that the worm gear 10 will not rotate, thereby achieving the limit and fixation of the side protection plate 17 and the lower protection plate 18.

[0030] Workflow: When the gate 4 is open, and the sealing groove 6 needs to be protected by the side protection plate 17 and the lower protection plate 18, the operator first pulls the locking screw 20 out from the inside of the worm gear 10. Then, the operator rotates the worm gear 10 by using the handwheel 9, causing the worm gear 10 to rotate the worm wheel 12. The worm wheel 12 then, through the connecting block 14, the fixing rod 15, and the connecting frame 16, causes the side protection plate 17 and the lower protection plate 18 to cover the sealing groove 6. When it is necessary to re-lock the gate 4 with the sealing groove 6... When assembled, the operator rotates the worm gear 10 in the reverse order of the above operation, so that the worm gear 10, through the worm wheel 12, connecting block 14, fixing rod 15 and connecting frame 16, gradually rotates the side protection plate 17 and the lower protection plate 18 out from the inside of the sealing groove 6, so that the side protection plate 17 and the lower protection plate 18 are on the side of the sealing groove 6, ensuring that the side protection plate 17 and the lower protection plate 18 will not affect the engagement of the gate 4 and the sealing groove 6, and at the same time, the locking screw 20 achieves the limiting and fixing between the gate frame 1 and the worm gear 10.
