Description

A type of water conservancy sewage barrier bar Technical Field

[0001] This utility model relates to the field of barrier grid technology, and in particular to a water conservancy sewage barrier grid. Background Technology

[0002] A water conservancy sewage barrier screen, also known as a screen or trash rack, is a water conservancy facility used to control water flow and intercept pollutants. It consists of a set of parallel metal bars, typically placed obliquely on the main gravity-flow channel before the sewage lift pump's collection tank. Water conservancy sewage barrier screens are an important component of water resource protection, effectively preventing pollutants from flowing into water bodies, reducing water pollution, protecting the aquatic ecosystem, and maintaining the sustainable use of water resources.

[0003] Barrier screens intercept large, suspended or floating solids in sewage, such as grass, plastic products, fibers, and other household waste. This results in a significant accumulation of debris on the water-facing side of the barrier screen. Currently, lifting rubber scrapers are commonly used to raise the debris to the surface for easier collection. However, these scrapers wear down over time and require timely replacement. Replacing scrapers with numerous screws is cumbersome, so a new type of hydraulic sewage barrier screen is needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a water conservancy sewage barrier grille to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a water conservancy sewage barrier grille, comprising a drainage ditch body, a grille plate fixedly connected to the inner wall of the drainage ditch body, a top frame fixedly connected to the top surface of the drainage ditch body by bolts, a screw lifting mechanism fixedly connected to the top of the top frame, a connecting plate rotatably connected to the screw of the screw lifting mechanism via a bearing, a collection box fixedly connected to the side of the connecting plate, a support plate fixedly connected to the top surface of the collection box, a spring fixedly connected to the inner side of the support plate, a guide rod fixedly connected to the end of the spring away from the support plate, the guide rod slidably connected to the support plate, a movable frame fixedly connected to the end of the guide rod away from the spring, an assembly plate slidably connected to the top of the movable frame, a rubber scraper fixedly connected to the top surface of the assembly plate, a baffle fixedly connected to the side of the movable frame away from the assembly plate, a threaded post threadedly connected to one side of the baffle, a locking plate rotatably connected to one end of the threaded post via a bearing, a clamping plate fixedly connected to the inner side of the locking plate, and the clamping plate engaging with the assembly plate.

[0007] Preferably, in any of the above embodiments, an arc-shaped plate is fixedly connected to the side of the mobile frame, a rubber anti-collision pad is fixedly connected to the bottom of the collection box, and the arc-shaped plate is located above the collection box.

[0008] Preferably, in any of the above embodiments, the side of the assembly plate is fixedly fitted with several reinforcing ribs by bolts, and the top of the reinforcing ribs is fixedly connected to the rubber scraper.

[0009] Preferably, in any of the above solutions, a pin is fixedly connected to the top surface of the movable frame, and a pin hole is provided on the bottom surface of the assembly plate, wherein the pin is slidably connected to the assembly plate through the pin hole.

[0010] Preferably, in any of the above solutions, a limiting post is fixedly connected to the inner side of the locking plate, and the limiting post is slidably connected to the baffle.

[0011] Preferably, in any of the above solutions, the side of the assembly plate is provided with a slot, and the card plate is engaged with the assembly plate through the slot.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] When sewage is discharged inside the main body of the drainage ditch, debris is blocked when the sewage flows through the grating plate, which can intercept and retain debris in the sewage. When a certain number of debris accumulates on the water-facing side of the grating plate, the screw lifting mechanism can be activated to drive the collection box upward. At this time, the rubber scraper will slide relative to the grating plate, and the debris in the water can be collected through the collection box. The rubber scraper can scrape off the debris adhering to the grating plate, and the scraped debris can fall into the collection box along the curved plate. Moreover, the rubber scraper can stay in close contact with the grating plate under the compression of the spring, which can improve the cleaning effect of debris. When the rubber scraper becomes worn, the threaded column can be twisted. Through the threaded transmission, the locking plate can be moved away from the assembly plate until the locking plate moves out of the slot, which can release the locking of the assembly plate. The assembly plate can be quickly removed from the moving frame, which can facilitate the disassembly and replacement of the rubber scraper. Attached Figure Description

The debris in the sewage can be intercepted. When a certain number of debris accumulates on the water-facing surface of the grating plate 2, the screw lifting mechanism 4 can be activated to drive the collection box 6 to move upward.

[0031] 2): The rubber scraper 12 will slide relative to the grid plate 2. The collection box 6 can collect the debris in the water. The rubber scraper 12 can scrape off the debris adhering to the grid plate 2, and the scraped debris can fall into the collection box 6 along the arc plate 17.

[0032] 3): When the rubber scraper 12 wears out, the threaded post 14 can be twisted.

[0033] In summary, this hydraulic sewage barrier bar, when performing sewage discharge operations inside the main body 1 of the drainage ditch, blocks debris as sewage flows through the bar plate 2, effectively intercepting debris in the sewage. When a certain number of debris accumulates on the water-facing surface of the bar plate 2, the screw lifting mechanism 4 can be activated to move the collection box 6 upwards. At this time, the rubber scraper 12 will slide relative to the bar plate 2, allowing the collection box 6 to collect the debris in the water. The rubber scraper 12 can also scrape off the debris adhering to the bar plate 2. Furthermore, the scraped debris... The debris can fall into the collection box 6 along the arc plate 17, and the rubber scraper 12 can stay in close contact with the grid plate 2 under the compression of the spring 8, which can improve the cleaning effect of debris. When the rubber scraper 12 is worn, the threaded column 14 can be twisted, and the locking plate 15 can be driven away from the assembly plate 11 through the threaded transmission until the locking plate 16 moves out of the slot 23, which can release the locking of the assembly plate 11. The assembly plate 11 can be quickly removed from the moving frame 10, which can facilitate the disassembly and replacement of the rubber scraper 12.
