Description

Technical Field

[0001] This utility model relates to the field of trash rack technology, and in particular to a cleaning mechanism and a trash rack. Background Technology

[0002] Trash grates are key facilities installed at the inlet of water diversion channels in hydropower stations, pumping stations, and water conservancy projects. They are mainly used to intercept floating objects and debris (such as branches, garbage, aquatic plants, plastics, etc.) in the water flow, preventing these objects from entering the turbines, pumps, or gates and causing equipment blockage, wear, or even shutdown accidents.

[0003] The trash racks of hydropower stations are installed in the water flow channel. During normal operation, there is a certain pressure difference between the water level upstream and downstream of the rack. Under normal circumstances, the pressure difference is small, and the water flows smoothly. However, when blocked, debris accumulates on the rack surface, causing the water level upstream to rise and the water level downstream to drop, resulting in a significant increase in the pressure difference and potential safety hazards.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1

[0033] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a cleaning mechanism, including:

[0034] Drive component 1 is fixedly mounted on the equipment;

[0035] The moving part 2 is connected to the driving part 1, and the driving part 1 can provide driving force to the moving part 2;

[0036] The driving component 1 provides power to the moving component 2, causing the moving component 2 to move on the surface of the equipment, thereby enabling the moving component 2 to clean the surface of the equipment.

[0037] By providing a stable power output to the moving part 2 through the driving component 1, the moving part 2 can move smoothly on the surface of the equipment. The moving part 2 performs moving operations on the surface of the equipment, thereby achieving a comprehensive cleaning of the equipment surface. This cleaning method not only improves cleaning efficiency, but also ensures the cleanliness and maintenance effect of the equipment surface.

[0038] Furthermore, the drive component 1 includes a limiting member 11 fixedly installed on the equipment, and a lead screw 12 symmetrically arranged with the limiting member 11. The lead screw 12 is connected to the drive assembly 13, and the moving component 2 is connected to the limiting member 11 and the lead screw 12.

[0039] The lead screw 12 is also fixed on the equipment and is connected to the lead screw 12 and the limiting member 11 through the moving part 2. When the lead screw 12 rotates, the moving part 2 can move vertically due to the limiting effect of the limiting member 11 on the moving part 2, thereby cleaning the surface of the equipment.

[0040] Furthermore, the moving part 2 includes a collecting hopper 21, which is slidably connected to the limiting member 11, and the collecting hopper 21 is threadedly connected to the lead screw 12;

[0041] The inner side of the collecting hopper 21 has a cavity that can collect impurities. The bottom of the collecting hopper 21 is connected to the limiting member 11 and the lead screw 12 respectively. The limiting member 11 and the lead screw 12 together limit the collecting hopper 21. By rotating the lead screw 12, the collecting hopper 21 moves vertically, thereby cleaning the surface of the equipment.

[0042] Furthermore, the bottom of the collecting hopper 21 is connected to the collecting chamber 22, and the side wall of the collecting chamber 22 is provided with multiple sets of through grooves 23; the bottom of the collecting hopper 21 is connected to the collecting chamber 22, and by providing through grooves 23, when the collecting hopper 21 moves the collecting chamber 22 upward to clean the equipment, water can be discharged from the collecting chamber 22, and impurities are collected in the collecting chamber 22, while reducing the resistance when the collecting hopper 21 rises.

[0043] Furthermore, the drive assembly 13 includes a motor 131 mounted on the device, the output end of the motor 131 is connected to a first bevel gear 132, and a second bevel gear 133 is fixedly connected to the top of the lead screw 12, with the first bevel gear 132 meshing with the second bevel gear 133;

[0044] The connecting shaft of the motor 131 is connected to the first bevel gear 132, so that the motor 131 can drive the first bevel gear 132 to rotate. When the collection hopper 21 is needed, the motor 131 drives the first bevel gear 132 to rotate, the first bevel gear 132 drives the second bevel gear 133 to rotate, and then drives the lead screw 12 to rotate, so that the lead screw 12 provides driving force to the collection hopper 21, driving the collection hopper 21 to clean the equipment.

[0045] Example 2

[0046] Reference Figures 1-4 This is the second embodiment of the present utility model. Unlike the previous embodiment, this embodiment also includes a sealing component 3, which is disposed on the collecting hopper 21 and located at the top of the collecting cavity 22. The sealing component 3 is provided with a cooperating contact component 4.

[0047] The contact element 4 is located above the sealing component 3, which is positioned on the collection hopper 21. The sealing component 3 is located at the top of the collection chamber 22. In this embodiment, the sealing component 3 seals the top of the collection chamber 22. After the impurities are cleaned, they first enter the collection hopper 21. Subsequently, the collection hopper 21 continues to move upward, causing the contact element 4 to contact the sealing component 3. The sealing component 3 is moved by the contact, which in turn opens the top of the collection chamber 22, allowing the impurities in the collection hopper 21 to fall into the collection chamber 22. When the collection hopper 21 moves downward, the sealing component 3 closes the top of the collection chamber 22, preventing the cleaned and collected impurities from falling back into the water, thereby improving the collection effect of impurities.

[0048] Furthermore, the sealing component 3 includes a sliding member 31 that is slidably disposed on the collection hopper 21, and a limiting member 11 is provided on one side of the collection hopper 21, and the sliding member 31 is slidably connected to the limiting member 11;

[0049] The collecting hopper 21 is slidably connected to the top of the collecting chamber 22 by a sliding member 31. The sliding member 31 passes through the side of the collecting hopper 21 away from the equipment, so that the sliding member 31 is slidably connected to the limiting member 11. The sliding member 31 is restricted from moving by the limiting member 11 and can only slide laterally.

[0050] Furthermore, the limiting component 32 includes a fixed post 321 fixedly mounted on the collection hopper 21, a sliding member 31 slidably connected to the fixed post 321, and a spring 322 provided between the outer wall of the collection hopper 21 and the end of the fixed post 321.

[0051] Two sets of fixed columns 321 are fixedly provided on the side of the collection hopper 21 away from the equipment. The sliding member 31 passes through one end of the collection hopper 21 and is slidably connected to the fixed column 321, so that the fixed column 321 can limit the collection hopper 21 and the collection hopper 21 can only slide laterally. At the same time, the spring 322 is sleeved on the outside of the fixed column 321, and the two ends of the spring 322 abut against the outer wall of the collection hopper 21 and the end of the fixed column 321, respectively.

[0052] When the contacting member 4 abuts against the sliding member 31, causing it to move away from the equipment and thus opening the top of the collecting chamber 22, the spring 322 is abutted and contracted. When the collecting hopper 21 moves downward away from the contacting member 4, the spring 322 pushes the sliding member 31 to reset, thus closing the top of the collecting chamber 22 again. At the same time, the sliding member 31 has a slot, so that when the collecting hopper 21 rises, water can be discharged through the slot, and impurities are collected in the collecting hopper 21, which can reduce the resistance when the collecting hopper 21 rises.

[0053] Furthermore, the collection bucket 21 is provided with a passage 33 that cooperates with the contacting part 4;

[0054] By providing an opening 33 on the collection hopper 21, the opening 33 is positioned to cooperate with the contact member 4. When the contact member 4 contacts the sliding member 31, the opening 33 cooperates with the contact member 4 to enable the collection hopper 21 to move continuously. The contact member 4 can resist the movement of the sliding member 31, thereby opening the top of the collection cavity 22.

[0055] In summary, the sealing component 3 allows impurities to be collected in the collection chamber 22, while also preventing impurities from escaping and causing secondary pollution.

[0056] In summary, the design of the enclosed component 3 not only achieves the directional collection of impurities, allowing various impurities to be guided and collected within the collection chamber 22, ensuring effective isolation and centralized treatment of impurities, but also fundamentally prevents impurities from re-escapeing into the surrounding environment while efficiently fulfilling its collection function, thus avoiding the recurrence of equipment blockage problems caused by impurity diffusion. This not only improves the operating efficiency and stability of the equipment but also provides strong support for long-term equipment maintenance and environmental protection.

[0057] The rest of the structure is the same as in Example 1.

[0058] Example 3

[0059] Reference Figures 1-4 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a trash rack, including the aforementioned cleaning mechanism, and...

[0060] The debris-blocking component 5 includes two sets of positioning posts 51, with a filter screen 52 disposed between the two sets of positioning posts 51.

[0061] The drive component 1 is mounted on the positioning column 51, and the moving component 2 is in contact with the surface of the filter screen.

[0062] In this embodiment, the limiting member 11 and the lead screw 12 are respectively fixed on opposite sides of two sets of positioning posts 51. The collecting hopper 21 is sleeved on the limiting member 11 and the lead screw 12. The motor 131 is installed on one side of one set of fixing posts 321. The output end of the motor 131 extends out of the fixing post 321 and is connected to the first bevel gear 132, so that the first bevel gear 132 meshes with the second bevel gear 133 at the top of the lead screw 12. The bottom side of the collecting hopper 21 is in contact with the surface of the filter screen, so that when the collecting hopper 21 rises... It can scrape and clean the impurities on the surface of the filter screen. The removed impurities are collected by the collection hopper 21. The side of the contact member 4 corresponding to the collection hopper 21 has an inclined surface. The contact member 4 is fixed on the surface of the filter screen and located above the collection hopper 21. When the collection hopper 21 continues to move upward, the inclined surface of the contact member 4 contacts one side of the sliding member 31, causing the sliding member 31 to slide away from the filter screen. At this time, the spring 322 is contracted by the contact, the top of the collection chamber 22 opens, and the garbage in the collection hopper 21 falls into the collection chamber 22.

[0063] When the collection hopper 21 moves downward, the spring 322 pushes the sliding member 31 to reset, so that the top of the collection chamber 22 is sealed, thus preventing the cleaned garbage from floating in the water and avoiding impurities from clogging the filter screen again. After the equipment has been used for a period of time, the impurities in the collection chamber 22 can be cleaned.

[0064] In summary, by placing the cleaning mechanism at the front end of the filter screen, it can clean and collect impurities on the surface of the filter screen, thereby avoiding the problem of poor water flow caused by filter screen blockage due to impurities. This ensures the normal use of the filter screen while collecting and cleaning impurities in the water, thus improving the water environment.
