DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] The present invention provides a hydraulic opening and closing system with a continuous locking function for a water conservancy project, which comprises a loading frame 1 and a hydraulic mechanism 2. A gate 3 is provided at the output end of the hydraulic mechanism 2. First slide grooves corresponding to the gate 3 are provided on both sides of the loading frame 1. The gate 3 slides up and down along the first slide groove through the hydraulic mechanism 2.

[0032] Sliding components 31 and first grooves corresponding to the sliding components 31 are provided on both sides of the gate 3. The sliding components 31 are located inside the first grooves. The sliding components 31 include a sliding plate 311 and a roller 312. The roller 312 is located at one end of the sliding plate 311 away from the gate 3. The roller 312 contacts and slides with the first slide groove. The sliding plate 311 and the first groove are connected by a first spring 313.

[0033] The loading frame 1 is provided with locking components 11 corresponding to the sliding components 31 on both sides, and the locking components 11 include locking blocks 111 and telescopic rods 112. The loading frame 1 is provided with second grooves corresponding to the locking components 11 on both sides, and the locking components 11 are located inside the second grooves. The locking blocks 111 are slidably connected to the second grooves through the telescopic rods 112. The two ends of the locking blocks 111 close to the sliding plate 311 are designed as arcs;

[0034] Cleaning components 32 are provided on both sides of the bottom of the gate 3. The cleaning components 32 include support rods 321. A first cleaning block 322 corresponding to the cleaning component 32 is provided at the bottom of the gate 3. The first cleaning block 322 is fixedly connected to the gate 3. The top of the support rod 321 is hinged to the first cleaning block 322. The first cleaning block 322 is in contact with the first slide groove. A second cleaning block 323 is provided at one end of the bottom of the support rod 321 away from the first cleaning block 322. The second cleaning block 323 is hinged to the support rod 321. A second slide groove 12 corresponding to the second cleaning block 323 is provided at the bottom of the loading frame 1. The second cleaning block 323 slides in the second slide groove 12. The second slide groove 12 is provided with a plurality of first through holes 121 that penetrate therethrough.

[0035] The bottom of the gate 3 is provided with a third groove 33 corresponding to the support rod 321 and the second cleaning block 323;

[0036] A filter assembly 4 corresponding to the gate 3 is provided on the loading frame 1, and floating objects are intercepted by the filter assembly 4.

[0037] When the gate 3 needs to be opened during use, the hydraulic mechanism 2 drives the gate 3 to start moving upward along the first slide groove, and the rollers 312 on both sides of the gate 3 slide along the first slide groove. When the rollers 312 slide to the position of the locking block 111, the first spring 313 begins to bear the force of the sliding plate 311 to move in the direction of the gate 3, and the telescopic rod 112 begins to telescope and drives the locking block 111 to move in the direction of the gate 3. One side of the locking block 111 is stuck in the first groove, and the other side is located in the second groove. The gate 3 is locked by the locking block 111, and the filter assembly 4 intercepts floating objects in the water. During the rising process of the gate 3, the support rod 321 is driven to move by the first cleaning block 322, and the support rod 321 drags the second cleaning block 323 to move to both sides. During the movement, the second cleaning block 323 cleans the garbage in the second slide groove 12 The first cleaning block 322 cleans the garbage in the first chute on both sides of the loading frame 1 during the descent of the gate 3 to ensure that the gate 3 can slide smoothly in the first chute. At the same time, the second cleaning block 323 continues to clean the second chute 12. When the gate 3 is closed, the support rod 321 tends to be horizontal, and the second cleaning block 323 is inserted into the third groove 33 at the bottom of the gate 3 to ensure the sealing of the gate 3 and the bottom of the loading frame 1.

[0038] Compared with the prior art, the gate is continuously locked by the cooperation between the locking assembly 11 and the sliding assembly 31. When the gate 3 rises to its proper position, the locking block 111 is automatically snapped into the first groove under the action of the telescopic rod 112, providing a stable locking force and effectively preventing the gate from accidentally moving. Cleaning assemblies 32 are arranged on both sides of the bottom of the gate 3, including a support rod 321, a first cleaning block 322 and a second cleaning block 323. During the lifting process of the gate, the first cleaning block 322 and the second cleaning block 323 automatically clean the garbage in the first chute 12 and the second chute 12 respectively, and the garbage is washed away by the water flow through the first through hole 121, realizing the automatic cleaning function and reducing the maintenance cost. A third groove 33 is arranged at the bottom of the gate 3. When the gate is closed, the support rod 321 tends to be horizontal, and the second cleaning block 323 is snapped into the third groove 33, effectively improving the sealing between the gate and the bottom of the loading rack and reducing water leakage.

[0039] Example 2

[0040] In the above embodiment, the filter assembly 4 is directly exposed to the water flow. Long-term or high-intensity water flow impact may cause deformation and damage. Therefore, the embodiment of the present application optimizes the filter assembly 4 to a certain extent based on the above embodiment.

[0041] In this embodiment, the filter assembly 4 includes a filter frame 41 and a buffer assembly 42. The filter frame 41 is provided with a plurality of first filter holes. The filter frame 41 is connected to the loading frame 1 through the buffer assembly 42. The buffer assembly 42 includes a connecting rod 421 and a buffer rod 423. The buffer assembly 42 is symmetrically arranged on both sides of the filter frame 41 near the gate 3. The connecting rod 421 is located at the upper and lower ends of the filter frame 41. The buffer rod 423 is provided with a connecting block with a sliding connection. The two ends of the connecting rod 421 are respectively hinged to the filter frame 41 and the connecting block. The buffer rod 423 is provided with a second spring 422 corresponding to the connecting block.

[0042] When in use, floating objects in the water flow are filtered and intercepted through the first filter holes on the filter frame 41. During the interception process, the water flow will impact the filter frame 41. The filter frame 41 moves toward the gate 3 under the action of the water flow. During the movement, the filter frame 41 drives the connecting rod 421 to move. The connecting rod 421 pushes the connecting block to expand to both sides, and the second spring 422 begins to be stressed to offset the force applied to the filter frame 41, thereby ensuring the stability of the filter frame 41 and preventing it from being damaged by direct impact of the water flow.

[0043] Compared with the prior art, the buffer assembly 42 provides effective buffering and support for the filter frame 41. When the water flow impacts the filter frame 41, the connecting rod 421 pushes the connecting block to expand to both sides, and the second spring 422 is stressed and offsets part of the impact force, thereby protecting the filter frame 41 from damage and significantly enhancing its impact resistance. The buffer assembly 42, through the hinged design of the connecting rod 421 and the connecting block, and the elastic effect of the second spring 422, enables the filter frame 41 to maintain a relatively stable position when impacted by the water flow, thereby improving the overall stability of the filter assembly and ensuring the continuity and reliability of the filtering effect. When the water flow intensity increases or the floating matter content increases, the buffer assembly 42 can absorb and disperse more impact force, maintain the stability of the filter frame 41, and ensure the continuity of the filtering effect.

[0044] Example 3

[0045] The above embodiment uses a fixed-size filter hole, and the diameter of the water flow cannot be adjusted according to actual needs, making it difficult to adapt to the interception needs of floating objects of different sizes. It is easy to shake up and down due to uneven force under the impact of water flow. Therefore, the embodiment of the present application optimizes the filter frame 41 to a certain extent based on the above embodiment.

[0046] In this embodiment, a plurality of horizontally distributed unloading strips 412 are provided on the side of the filter frame 41 away from the gate 3, and the unloading strip 412 is located between two adjacent filter holes. A first filter 411 is provided in the buffer assembly 42, and a second filter hole corresponding to the first filter hole is provided on the first filter 411. The first filter 411 is connected to the inner wall of the filter frame 41 on both sides by an air bag 413, and the first filter 411 is slidably connected to the filter frame 41.

[0047] When in use, the unloading bar 412 starts to be inflated according to the size of the floating object, the air bag 413 on one side of the first filter screen 411 is inflated and the other side is deflated synchronously, and the first filter screen 411 starts to slide inside the filter frame 41. During the sliding process of the first filter screen 411, the second filter hole on the first filter screen 411 begins to overlap with the first filter hole on the filter frame 41, and the overlapping position of the first filter hole and the second filter hole is different with the different pushing distances, thereby adjusting the diameter of the water flow passing through and the size of the intercepted floating objects. During the interception process, the filter frame 41 is easily shaken up and down by the impact of the water flow, and the unloading bar 412 on the filter frame 41 can segment the water waves themselves, interrupt part of the impact of the water waves, and reduce the impact on the filter frame 41.

[0048] Compared with the prior art, the first filter screen 411 and the airbag 413 realize dynamic adjustment of the filter hole. The airbag 413 on one side of the first filter screen 411 is inflated while the airbag 413 on the other side is deflated synchronously, so that the first filter screen 411 slides inside the filter screen frame 41. As the sliding distance changes, the overlapping position of the second filter hole on the first filter screen 411 and the first filter hole on the filter screen frame 41 changes, thereby adjusting the diameter of the water flow to meet the interception requirements of different floating objects. The filter screen frame 41 is provided with a force unloading bar 412, which is located between two adjacent filter holes and can divide the water waves themselves and interrupt part of the impact of the water waves. This design effectively reduces the impact on the filter screen frame 41, enhances the stability of the equipment, and reduces shaking.

[0049] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
