All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figures 1-4, the present invention provides the following technical solutions: An efficient self-cleaning mechanical equipment for a hydropower station trash rack, including a support assembly 1. There are two support assemblies 1. An interception assembly 2 is arranged between the two support assemblies 1. A top mounting plate 7 is fixedly connected above the two support assemblies 1. A winding assembly 6 is fixedly connected above the top mounting plate 7. The winding assembly 6 is connected to the interception assembly 2 through a steel cable 3. A cleaning and collection device 4 is fixedly installed on one side of the top mounting plate 7. A shielding and lighting device 5 is arranged outside the winding assembly 6.

[0026] Specifically, the cleaning and collection device 4 includes a support plate 41, a reduction motor 42, a collection assembly 43, a lead screw 44, a cleaning brush 46, and a lifting plate 47. A support plate 41 is fixedly installed on one side of the top mounting plate 7. A reduction motor 42 is fixedly installed above the support plate 41. A lead screw 44 is fixedly connected below the reduction motor 42 and at a position inside the support plate 41. A lifting plate 47 is installed on the outside of the lead screw 44 and below the support plate 41 through threads. A cleaning brush 46 is fixedly installed on one side of the lifting plate 47 close to the steel cable 3. A collection assembly 43 is fixedly installed on the side of the lifting plate 47 away from the cleaning brush 46.

[0027] By adopting the above technical solutions, it enables the staff to clean the dirt contaminated when intercepting the interception assembly 2 through the cooperation of structures such as the lead screw 44 and the cleaning brush 46 when needed, thereby reducing the difficulty of the cleaning work and alleviating the labor burden of the staff.

[0028] Specifically, the cleaning and collection device 4 further includes a guide rod 45. A guide rod 45 is fixedly installed below the support plate 41 and at a position between the lead screw 44 and the cleaning brush 46.

[0029] By adopting the above technical solutions, it enables the equipment to guide the movement of the lifting plate 47 through the guide rod 45, thereby preventing the lifting plate 47 from rotating and deviating during the movement, and further ensuring the normal progress of the work.

[0030] Specifically, the collection assembly 43 includes a collection box 431, a threaded block 432, a suction pipe 433, a filter screen 435, and a pump body 437. A collection box 431 is fixedly installed on the side of the lifting plate 47 away from the cleaning brush 46. A threaded block 432 is installed on the top of the collection box 431 through threads. A filter screen 435 is arranged inside the collection box 431. A plurality of pump bodies 437 are fixedly installed below the collection box 431. A suction pipe 433 is fixedly installed on the side of the collection box 431 away from the lifting plate 47.

[0031] By adopting the above technical solution, the problem that the staff can collect garbage and other objects on the water surface through the cooperation of structures such as the collection box 431 and the pump body 437 when needed is solved, thereby reducing the difficulty of collecting garbage and other objects on the water surface and reducing the labor burden of the staff.

[0032] Specifically, the collection assembly 43 further includes an elastic rubber ring 434 and a vibrator 436. The collection box 431 and the filter screen 435 are connected through the elastic rubber ring 434, and a vibrator 436 is fixedly installed below the filter screen 435.

[0033] By adopting the above technical solution, the staff can drive the filter screen 435 to vibrate through the vibrator 436 when needed, thereby preventing the filter screen 435 from being blocked. The elastic rubber ring 434 can prevent the vibration from affecting other structures through elastic deformation.

[0034] When this embodiment is in use, when the hydropower station needs to use mechanical equipment for trash interception work, the two support assemblies 1 are fixed at the working position. The staff operates the winding assembly 6 on the top mounting plate 7 to wind the steel cable 3, thereby adjusting the height of the interception assembly 2. Then, the dirty and garbage on the water surface are intercepted by the interception assembly 2. The staff can start the reduction motor 42 on the support plate 41 of the cleaning and collection device 4, thereby driving the lead screw 44 to rotate. The lead screw 44 is threadedly connected to the lifting plate 47, and the lifting plate 47 is slidably connected to the guide rod 45. Therefore, the lead screw 44 drives the lifting plate 47 and structures such as the cleaning brush 46 thereon to move up and down, thereby cleaning the dirt contaminated during the interception work of the interception assembly 2. In addition, the staff can operate the reduction motor 42 to drive the lifting plate 47 and the collection assembly 43 thereon to move until the suction pipe 433 moves to the height where the garbage floats. Then, each pump body 437 is started. Under the action of each pump body 437, the garbage and water pass through the suction pipe 433 and are sucked into the collection box 431. Then, the water passes through the filter screen 435 and each pump body 437 and is discharged, while the garbage is blocked by the filter screen 435 and remains in the collection box 431. The staff can start the vibrator 436 to drive the filter screen 435 to vibrate, thereby preventing the filter screen 435 from being blocked. The elastic rubber ring 434 can prevent the vibration from affecting other structures through elastic deformation. After the collection is completed, each pump body 437 can be closed. The staff can regularly unscrew the threaded block 432 to take out the collected garbage for use.

[0035] Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 lies in that: the shielding lighting device 5 includes a shielding plate 51, connecting columns 52 and a transparent shell 53. On the side of the top mounting plate 7 away from the support plate 41, two connecting columns 52 are fixedly installed. Above the two connecting columns 52, a transparent shell 53 is fixedly connected. Above the transparent shell 53, a shielding plate 51 is arranged.

[0037] By adopting the above technical solution, the device can intercept external heavy rain and the like through the cooperation of structures such as the shielding plate 51, thereby reducing the possibility of the device being adversely affected and better meeting the working needs.

[0038] Specifically, the shielding lighting device 5 further includes dampers 55 and an elastic rubber frame 56. An elastic rubber frame 56 is fixedly connected between the transparent shell 53 and the shielding plate 51. Between the transparent shell 53 and the shielding plate 51 and at a position inside the elastic rubber frame 56, a plurality of dampers 55 are fixedly connected.

[0039] By adopting the above technical solution, the device can buffer the impact brought by external heavy rain and the like through the cooperation of the dampers 55 and the elastic rubber frame 56, thereby improving the protection ability of the shielding lighting device 5.

[0040] Specifically, the shielding lighting device 5 further includes lighting lamps 54. A plurality of lighting lamps 54 are fixedly installed inside the transparent shell 53.

[0041] By adopting the above technical solution, the staff can perform certain auxiliary lighting through the lighting lamps 54 when needed, so as to better cope with the situation of insufficient light in some cases, and thus ensure the normal progress of the work.

[0042] When this embodiment is in use, in daily work, the shielding plate 51 in the shielding lighting device 5 can shield and block external heavy rain and the like. The dampers 55 and the elastic rubber frame 56 can buffer the impact brought by external heavy rain and the like. In addition, the staff can start each lighting lamp 54 in the transparent shell 53 for auxiliary lighting when needed to cope with the situation of insufficient light. The connecting columns 52 play a role of connection and fixation.

[0043] The structure and principle of the support assembly 1 composed of a fixed support and a guide groove, the interception assembly 2 composed of a connecting support rod, a vertical plate, a partition plate, a conical nail, a receiving plate and a reinforcing block, a steel cable 3, a winding assembly 6 composed of a fixed block, a core shaft, a winding drum and a brake motor, and a top mounting plate 7 and the structure thereon have been disclosed in a sewage interception device for a hydropower station disclosed in Chinese patent application No. 201921717997.7. Its working principle is that when working, the water flow drives the debris to hit the conical nail, so that the conical nail is inserted into the debris, so that the position of the debris is fixed, and large debris is avoided. At the water inlet, after long-term use, the debris in the conical nail needs to be cleaned. First, the brake motor needs to be turned on. When the brake motor rotates, the coupling will cause the core shaft to rotate together. When the core shaft rotates, the reel will rotate accordingly. When the reel rotates, the steel cable will gradually wrap around the surface of the reel, and the steel cable will be tightened, so that the steel cable pulls the reinforcement block upward, and the vertical plate and the partition plate will move upward accordingly, and the conical nail will leave the bottom of the water and reach the surface of the water. The debris on the conical nail can be cleaned, and the receiving plate prevents the debris from falling back into the water when cleaning, thereby playing a shielding role.

[0044] The structure and principle of the vibrator 436 in the present invention have been disclosed in an easy-to-clean concrete mixing device disclosed in Chinese Patent Application No. 201821054815.8. Its working principle is composed of components such as springs, mass blocks, and motors. When the spring or mass block is subjected to external force from the motor, elastic deformation or displacement will occur, thereby generating vibration.

[0045] The structure and principle of the damper 55 in the present invention have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese Patent Application No. 201721446985.6. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0046] Working principle and usage process of the present invention: When a hydropower station needs to use mechanical equipment for trash interception work, two support assemblies 1 are fixed at the working position. The staff operates the cable winding assembly 6 on the top mounting plate 7 to wind the steel cable 3, thereby adjusting the height of the interception assembly 2. Then, the interception assembly 2 intercepts the dirt and garbage on the water surface. The staff can start the reduction motor 42 on the support plate 41 of the cleaning and collection device 4, which drives the lead screw 44 to rotate. The lead screw 44 is threadedly connected to the lifting plate 47, and the lifting plate 47 is slidably connected to the guide rod 45. Therefore, the lead screw 44 drives the lifting plate 47 and structures such as the cleaning brush 46 thereon to move up and down, thereby cleaning the dirt contaminated during the interception work of the interception assembly 2. In addition, the staff can operate the reduction motor 42 to drive the lifting plate 47 and the collection assembly 43 thereon to move until the suction pipe 433 moves to the height where the garbage floats. Then, start each pump body 437. Under the action of each pump body 437, the garbage and water pass through the suction pipe 433 and are sucked into the collection box 431. Then, the water passes through the filter screen 435 and each pump body 437 and is discharged, while the garbage is blocked by the filter screen 435 and remains in the collection box 431. The staff can start the vibrator 436 to drive the filter screen 435 to vibrate, thereby preventing the filter screen 435 from being blocked. The elastic rubber ring 434 can prevent the vibration from affecting other structures through elastic deformation. After the collection is completed, just turn off each pump body 437. The staff can regularly unscrew the threaded block 432 to take out the collected garbage for use. During daily work, the baffle plate 51 in the shielding lighting device 5 can block and intercept external heavy rain, etc. The damper 55 and the elastic rubber frame 56 can buffer the impact brought by external heavy rain, etc. In addition, the staff can start each lighting lamp 54 in the transparent shell 53 for auxiliary lighting when needed to cope with the situation of insufficient light. The connecting column 52 plays a role of connection and fixation.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
