Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering, specifically to a bar screen cleaning structure for water conservancy engineering. Background Technology

[0002] Hydraulic engineering screens are generally installed at the inlet of hydropower stations and pumping stations to intercept debris in the water flow, thereby protecting equipment such as turbines and pumps. However, over time, a large amount of debris accumulates on the surface of the screens. If not cleaned in time, this will affect the service life of the screens and the normal operation of the hydraulic equipment. Therefore, cleaning structures are needed to clean the hydraulic screens to ensure the normal flow of water. Existing cleaning mechanisms on the market use cleaning rakes installed on external conveying devices. The conveying device moves the cleaning rakes up and down to clean the screens.

[0003] However, the types of mesh openings on the existing market are different. Depending on the interception situation, the mesh openings on the bar can be set as round mesh openings, rectangular strip mesh openings, and rectangular mesh openings with equal spacing. When the mesh openings are evenly distributed with equal spacing, the traditional method of using a conveyor mechanism to drive the cleaning rake up and down cannot clean the bar. Therefore, manual cleaning and unblocking are the only options, which is very troublesome. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a screen cleaning structure for water conservancy projects, including a support component 1, which is used for supporting the work and is set on the outside of the water conservancy screen;

[0024] The lifting component 2 is disposed inside one side of the support component 1;

[0025] The cleaning component 3 is connected to the outside of the lifting component 2. It completes the cleaning work of the external grille through lifting. The cleaning component 3 includes cleaning wheel teeth 31 and connecting shaft 32 arranged at equal intervals. The cleaning wheel teeth 31 and connecting shaft 32 are detachable and installable.

[0026] This application provides a flexible cleaning component 3 for water conservancy projects. Specifically, in use, firstly, select an appropriate number of cleaning wheel teeth 31 and connecting shafts 32 according to the size of the screen. Then, splice the appropriate number of cleaning wheel teeth 31 and connecting shafts 32 so that their size corresponds to the size of the screen. Then, install them with the lifting component 2 on the support component 1. After installation, control the entire device to move to the outside of the screen, and the screen can be cleaned. When cleaning is required, the lifting component 2 needs to be activated so that it drives the cleaning component 3 to move up and down to complete the cleaning of the screen.

[0027] After cleaning, the scraped-off waste can be collected and processed using external grabs and transfer devices.

[0028] Among them, according to Figure 1 As shown, the support assembly 1 includes two support vertical rods 11 and a connecting horizontal rod 12. The connecting horizontal rod 12 is installed by the middle bolts of the two support vertical rods 11. One of the support vertical rods 11 has a hollow structure inside for the installation of the lifting assembly 2.

[0029] Specifically, by disassembling and installing the connecting crossbar 12 and the two supporting vertical bars 11, the cleaning component 3 can be fully exposed, thus facilitating the disassembly, installation, and maintenance of the cleaning component.

[0030] Furthermore, when controlling the cleaning component 3 to move up and down, according to Figure 2-3 As shown, the lifting assembly 2 includes a rotating screw 21 and a rotating sleeve 22. The bottom of the rotating screw 21 is connected to the bottom bearing of the hollow structure inside the support rod 11, and the top of the rotating screw 21 passes through the top of the support rod 11 and is connected to the control motor.

[0031] The rotating sleeve 22 has a threaded hole 221 in the middle for threaded connection with the outside of the rotating screw 21, and a polygonal first locking block 222 is provided on the outside of the rotating sleeve 22.

[0032] Specifically, the control motor needs to be started to drive the rotating screw 21 at the bottom to rotate. When the rotating screw 21 rotates, it will be threadedly connected to the threaded hole 221 inside the rotating sleeve 22. This causes the rotating sleeve 22 to drive the first locking block 222 at its top to move up and down in the limiting groove on the outer wall of the support vertical rod 11. Thus, the first locking block 222 will drive the cleaning component 3 connected at its top to move up and down.

[0033] Furthermore, according to Figure 4-6As shown, when the cleaning assembly 3 is assembled, a first connecting block 311 and a second connecting block 315 are respectively provided on both sides of the cleaning wheel tooth 31. The inner side of the first connecting block 311 is provided with a polygonal groove, and the second connecting block 315 is provided with a polygonal structure. Mounting grooves 313 are distributed at equal angles around the outer periphery of the cleaning wheel tooth 31. Mounting teeth 312 are provided inside the mounting grooves 313 to engage with them. A fastening screw 314 is provided between the through hole at the bottom of the mounting tooth 312 and the through hole on the outer wall of the cleaning wheel tooth 31. Nuts are provided on both sides of the fastening screw 314 for fixing.

[0034] The connecting shaft 32 is provided with a slot 321 and a second block 322 on both sides. The slot 321 engages with the second connecting block 315 and the two are fixed by fasteners. The second block 322 engages with the polygonal groove inside the first connecting block 311 and the second block 322 and the first connecting block 311 are fixed by fasteners.

[0035] When installing the cleaning wheel tooth 31 and the connecting shaft 32, the polygonal groove inside the first connecting block 311 on the outer side of the cleaning wheel tooth 31 needs to be engaged with the second locking block 322 on the connecting shaft 32. Then, it is fixed with fasteners. Then, the second connecting block 315 on the other side of the cleaning wheel tooth 31 is engaged with the locking groove 321 on the connecting shaft 32. Then, it is fixed with fasteners. In this way, all the installation and connection work of the cleaning wheel tooth 31 and the connecting shaft 32 is completed. After installation, it is necessary to ensure that both sides are connecting shafts 32. Then, the connecting shafts 32 on both sides are respectively installed and connected to the rotating sleeve 22 and the drive motor 4.

[0036] Specifically, when it is necessary to install the mounting tooth 312, simply engage the bottom of the mounting tooth 312 with the mounting groove 313, then pass the screw through the through hole on the mounting tooth 312 and the mounting groove 313, and finally tighten it with a nut.

[0037] The outermost side of the cleaning component 3 is provided with two connecting shafts 32. The second locking block 322 at the top of one of the connecting shafts 32 is connected to the groove inside the first locking block 222 by fasteners. The locking groove 321 at the top of the other connecting shaft 32 engages with the polygonal connecting block at the top of the drive motor 4, and the two are fastened together by fasteners. The drive motor 4 is provided with a mounting bracket, and a sliding block is provided on the outside of the mounting bracket to slide in the sliding groove outside the support rod 11.

[0038] When installing the cleaning component 3 with the rotating sleeve 22 and the drive motor 4, the outer slot 321 of one of the connecting shafts 32 on both sides needs to be engaged with the polygonal connecting block at the top of the drive motor 4, and the second slot 322 on the outside of the other connecting shaft 32 needs to be engaged with the groove inside the first slot 222. Finally, it can be fixed by fasteners, which can be bolts and nuts.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
