[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the embodiments described are only some embodiments of the invention, not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the invention.

[0031] Example 1: See Figures 1 to 7 ;

[0032] The present invention discloses a sluice buffering and protection mechanism, comprising symmetrically arranged power chambers 01, a guide bar 05 connected between two power chambers 01, a drive shaft connected between the two power chambers 01, a gate plate 02 connected to the drive shaft, a plurality of guide grooves 04 for water flow buffering and guiding are provided on the gate plate 02, and a guide plate 03 for guiding flow is also provided on the top of the gate plate 02. When the water flow hits the gate plate 02, the water flow is guided by the guide grooves 04 and the guide plates 03, so that the water flow tends to move upward, and then overflows or flows back through the guide plates 03, thereby removing part of the impact force to achieve the protection of the sluice. A power component for driving the shaft to rotate is provided in the power chamber 01 to flip the gate plate 02 to achieve water diversion.

[0033] In one embodiment, a flow-disturbing mechanism is further provided in the guide groove 04 for buffering the impact water. The flow-disturbing mechanism further disturbs the water to ensure the safety and stability of the gate plate 02 and the drive shaft, and further ensure the safety and stability of the power assembly.

[0034] In one embodiment, a cutting strip 08 is provided between the two guide grooves 04, and a flexible waterproof strip is provided between the gate plate 02 and the power chamber 01. The cutting strip 08 performs local water flow cutting and guidance, so that the water impacting the gate plate 02 is diverted and locally disturbed. The waterproof strip blocks the gap between the two sides of the gate plate 02 and the power chamber 01 to ensure the function of the sluice.

[0035] Example 2: Figure 1 、 Figure 2 and Figure 6-8 As shown, the difference between this embodiment and the first embodiment lies in the difference in the spoiler mechanism;

[0036] In this embodiment, the spoiler mechanism includes a mounting groove 16 that is slidably sleeved in the guide groove 04, and a flexible buffer sleeve 17 is provided at the bottom of the mounting groove 16. The bottom of the mounting groove 16 is provided with a flexible buffer sleeve 17. The buffer sleeve 17 is relatively fixed to the guide groove 04 and is filled with water. A plurality of diverter units are slidably sleeved in the mounting groove 16, and are used for diverting and unloading water and buffering water flow. The plurality of diverter units are connected in sequence, and the water flow impacts the buffer sleeve 17, so that the water in the buffer sleeve 17 flows out through one side. Since the flow rate of the liquid outflow is constant, a certain buffering can be obtained. The diverter unit diverts and unloads the water flow, and unloads the corresponding instantaneous impact and periodic impact.

[0037] In the second embodiment, the flow transfer unit includes a mobile box 19 that can be slidably sleeved in the installation groove 16, and a return bucket 22 is fixedly connected to the mobile box 19. The middle of the return bucket 22 is rotatably connected to a rotating tube 25, and a collecting bucket 24 is provided at the top of the rotating tube 25. A plurality of driving plates 23 are also connected to the outer wall of the rotating tube 25. When the water flow hits the mobile box 19, it can drive the mobile box 19 to move up and down along the installation groove 16 to perform preliminary unloading and mixing. At the same time, part of the water flow passes through the collecting bucket 24 and the rotating tube 25 into the mobile box 19. The synchronous flowing water can drive the driving plate 23 to rotate, further performing local The mixed flow unloading force is partially unloaded, and when part of the water contacts the reflux bucket 22, it disperses around to form a reverse water flow, and then further mixes the flow, and then unloads the impacting water in multiple directions to reduce instantaneous local impact. The outer side of the rotating tube 25 is also connected to a friction block in contact with the reflux bucket 22 to slow down the rotation speed of the rotating tube 25. The bottom of the mobile box 19 is also provided with an impact sleeve 29, and a plurality of elastic components 26 are provided in the impact sleeve 29. Both sides of the mobile box 19 are connected with a plurality of reflux pipes 21 for reflux backwashing of the liquid in the mobile box 19. The middle of the mobile box 19 on the same side as the reflux pipe 21 is fixedly connected with a guide pipe 18, which is located A connecting pipe 28 is connected between the two guide pipes 18 on the same moving box 19, one end of the connecting pipe 28 is connected to the impact sleeve 29, and the bottom of the impact sleeve 29 is connected to a supplementary pipe 27 connected to the buffer sleeve 17. A slidable sleeve 20 is provided between the guide pipes 18 on the two adjacent moving boxes 19. The sleeve 20 is fixed relative to the mounting groove 16. The middle of the sleeve 20 is connected to a flow control pipe 09 connected to the outside world. The flow control pipe 09 is connected to a flow control valve. The water entering the moving box 19 impacts the impact sleeve 29 for instantaneous buffering. At the same time, the water overflows through the return pipe 21 and is mixed again to achieve the rear It continues to buffer and unload the impact of water flow, and in the process of the mobile box 19 being impacted and moved, the space in the sleeve 20 is changed, so that the external water passes through the flow control valve, enters the impact sleeve 29 after passing through the connecting pipe 28, and further enters the buffer sleeve 17 through the supplementary pipe 27, exerting a reverse force on the vertical impact. When the vertical impact is too large, a reverse force can also be formed through the flow of fluid to perform buffering and pressure relief. At the same time, the combination of multiple devices forms multiple unloading mixed flow states, reducing local instantaneous impacts. At the same time, the mixed flow reduces subsequent peak impacts, thereby protecting the safety of the sluice.

[0038] Example 3: Figure 1-Figure 7 The difference between this embodiment and the first embodiment lies in the difference in the temporary support unit;

[0039] In this embodiment, the bottom end of the buffer sleeve 17 is also connected to a series tube 33, and the other end of the series tube 33 is connected to a temporary support unit for reducing the lever arm. The series tube 33 guides the fluid in the buffer sleeve 17 and then transports it into the snack support unit, triggering the snack support unit to take action.

[0040] In the third embodiment, the temporary support unit includes a through bar 14 connected to the riverbed, the through bar 14 is connected to the series pipe 33, and a plurality of supporting telescopic rods 15 are fixedly connected to the through bar 14. The fixed end of the supporting telescopic rod 15 is connected to the through bar 14, and the executive end of the supporting telescopic rod 15 is fixedly connected to the support plate 30. The support plate 30 matches the drive shaft. The water entering the moving box 19 enters the supporting telescopic rod 15, causing the executive end of the supporting telescopic rod 15 to move. The extension of the supporting telescopic rod 15 causes the support plate 30 to contact the drive shaft, thereby reducing the force torque of the drive shaft and protecting the stability and installation of the drive shaft. After the drive shaft is stable, it can further provide better support force to the gate plate 02, thereby further ensuring the safety and stability of the gate plate 02 and reducing its deformation.

[0041] Example 4: Figure 1-Figure 7 The difference between this embodiment and the first embodiment lies in the difference in the supporting mechanism;

[0042] In this embodiment, a support mechanism for mitigating instantaneous impact is also provided on the outside of the drive shaft. The support mechanism is connected to the temporary support unit. The support mechanism provides long-term support for the drive shaft. At the same time, when subjected to impact, it can provide a certain buffer to ensure the safety of the support shaft and the gate plate 02.

[0043] In the fourth embodiment, the supporting mechanism includes a fixed box 13 fixed relative to the riverbed, the fixed box 13 is connected to the installation box 31, a bearing 32 is provided in the installation box 31, the drive shaft and the bearing 32 are interference fit, and the installation of the two boxes facilitates the installation of the entire gate 02 and the drive shaft.

[0044] In the fourth embodiment, a diverter block 35 is fixedly connected to one side of the installation box 31, and a plurality of mixing holes 36 are provided on the diverter block 35. A protective cover 43 is connected between the fixed box 13 and the installation box 31. The mixing holes 36 cut the water flow that impacts the installation box 31 from the bottom, and at the same time, part of the water flow is guided and mixed through the mixing holes 36, thereby further reducing the instantaneous impact.

[0045] Example 5: Figure 8 and Figure 9 As shown, the difference between this embodiment and the first embodiment lies in the difference in the spoiler mechanism;

[0046] In this embodiment, the spoiler mechanism includes a plurality of rotating disks 06 arranged in the guide groove 04, the rotating disk 06 is rotatably connected to the gate plate 02, the gate plate 02 is hollow, and a plurality of support columns are arranged in the gate plate 02. One end of the rotating disk 06 is connected to the generator located in the gate plate 02, and the rotating disk 06 is located on one side of the guide groove 04 and is fixedly connected to a plurality of special-shaped pieces 07. When the impact water flow hits the gate plate 02, part of the water flow is diverted out through the gate plate 02 and the guide groove 04, realizing a certain mixed flow disturbance. At the same time, the flow of water drives the special-shaped piece 07 to rotate, further driving the rotating disk 06 and the driving end of the generator to rotate, generating electricity, unloading energy, reducing impact and recovering part of the energy at the same time. The rotation of the special-shaped piece 07 causes local water to mix, achieving a disturbance effect, and reducing the impact on the gate plate 02.
