[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Gates are control facilities used to close and open drainage channels. They are important components of hydraulic structures and can be used to intercept water flow, control water levels, and regulate flow. In daily operations, under the action of water flow and wind, a large amount of floating objects and other garbage will gather at the gates. When the gates are opened to release water, floating objects and other garbage will flow downstream along the river.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: floating objects and other garbage gather at the gate, affecting the opening and closing of the gate, and floating objects and other garbage float downstream, affecting irrigation.

The gate is provided with a driving device for driving the interception net and the push plate to slide.

[0007] By adopting the above technical solution, the interception net intercepts and collects the garbage at the gate, and the push plate cleans the garbage in the interception net, thereby improving the water quality and reducing the impact on the opening and closing of the gate.

[0012] The present application further provides that: the second transmission mechanism includes a second screw rod horizontally rotatably connected to the top of the gate, the second screw rod passes through the push plate and is threadedly connected to the push plate, and a driven gear is provided at one end of the second screw rod close to the first screw rod.

[0013] By adopting the above technical solution, the power mechanism drives the driven gear to rotate, the driven gear drives the second screw rod to rotate, and the second screw rod drives the push plate to slide, so the transmission is stable and accurate.

[0014] The present application further arranges: the power mechanism includes a motor arranged at the top of the gate, a sleeve is connected to the output shaft of the motor in an axial sliding manner along the output shaft, a fixing assembly for fixing the sleeve is provided on the output shaft, a driving gear meshing with the driven gear is provided on the sleeve, and a driving bevel gear meshing with the driven bevel gear is provided on the sleeve.

The driving device includes a power mechanism, a first transmission mechanism and a second transmission mechanism. Under the transmission action of the first transmission mechanism, the power mechanism can drive the interception net 2 to slide, and under the transmission action of the second transmission mechanism, the power mechanism can drive the push plate 3 to slide.

[0029] During daily operation, under the action of the power mechanism and the first transmission mechanism, the interception net 2 is lowered to the liquid level to intercept and collect garbage. When the interception net 2 collects a predetermined amount of garbage, under the action of the power mechanism and the first transmission mechanism, the interception net 2 rises to a predetermined height. At this time, the push plate 3 is located in the interception net 2 and abuts against the interception net 2. Under the action of the power mechanism and the second transmission mechanism, the push plate 3 slides from one end of the interception net 2 to the other end to clear out the garbage in the interception net 2, thereby improving the water quality and reducing the impact on the opening and closing of the gate 1.

[0030] Among them, the power mechanism includes a motor 11 installed on the left side of the top of the gate 1, the output shaft 12 of the motor 11 is in a horizontal state, and a sleeve 13 is slidably connected to the output shaft 12 of the motor 11 along the axial direction of the output shaft 12, and a fixing component for fixing the sleeve 13 is provided on the output shaft 12. A driving bevel gear 23 is welded to the left end of the sleeve 13, and a driving gear 33 is welded to the right end of the sleeve 13.

[0031] The first transmission mechanism includes a first screw rod 21 that is vertically rotatably connected to the left side of the gate 1, a first support block 41 is welded to the left side of the interception net 2, the first screw rod 21 passes through the first support block 41 and is threadedly connected to the first support block 41, and a driven bevel gear 22 meshing with the active bevel gear 23 is welded to the top of the first screw rod 21. The second transmission mechanism includes a second screw rod 31 that is horizontally rotatably connected to the top of the gate 1, a second support block 42 is welded to the push plate, the second screw rod 31 passes through the second support block 42 and is threadedly connected to the second support block 42, and a driven gear 32 meshing with the active gear 33 is welded to the left side of the second screw rod 31.

[0032] When it is necessary to drive the intercepting net 2 to rise or fall, push the sleeve 13 to slide along the output shaft 12, so that the active bevel gear 23 is engaged with the driven bevel gear 22, use the fixing assembly to fix the sleeve 13, start the motor 11, and under the transmission action of the active bevel gear 23, the driven bevel gear 22 and the first screw rod 21, the intercepting net 2 is raised or lowered.

[0033] When the push plate 3 needs to be driven to slide, the sleeve 13 is pushed to slide along the output shaft 12, so that the driving gear 33 is meshed with the driven gear 32, and the sleeve 13 is fixed by a fixing assembly, and the motor 11 is started. Under the transmission action of the driving gear 33, the driven gear 32 and the second screw rod 31, the push plate 3 slides. One motor 11 can drive the interception net 2 and the push plate 3 to slide respectively, which is energy-saving and environmentally friendly, and is consistent with the concept of sustainable development.

[0034] The fixing assembly includes a plug rod 14 vertically inserted into one side of the sleeve 13, and the bottom end of the plug rod 14 is spherical.

[0035] When the sleeve 13 is pushed to slide along the output shaft 12, under the action of the restoring force of the spring 17, the end of the rod 14 abuts against the output shaft 12 and slides along the output shaft 12. When one of the slots 16 is aligned with the socket 15, under the action of the restoring force of the spring 17, the rod 14 rebounds into the slot 16, and the sleeve 13 is fixed. The operation is convenient and the fixation is firm.

[0036] The implementation principle of a water conservancy gate for a river in an embodiment of the present application is as follows: when the interception net 2 is full of garbage, the active bevel gear 23 is meshed with the driven bevel gear 22, and the sleeve 13 is fixed using the insertion rod 14. Under the drive of the motor 11, the interception net 2 rises to a predetermined height under the transmission action of the active bevel gear 23, the driven bevel gear 22 and the first screw 21.
