Description

Technical Field

[0001] The utility model relates to the technical field of trash racks, in particular to an anti-blocking trash rack. Background Art

[0002] The anti-blocking trash rack of water conservancy projects is mainly used to intercept waste, weeds and other solid materials to avoid damage to water pumps and downstream facilities. Its main feature is that it can effectively prevent the accumulation and blockage of solid materials, thereby ensuring the normal operation of water pumps and downstream facilities.

[0003] At present, trash racks are generally made of multiple welded steel bars. When the trash rack is intercepting solid waste in the water, floating objects and other impurities are easy to adhere to the trash rack, which is easy to clog the trash rack and affect the use of the trash rack. At the same time, when the trash rack is intercepting garbage, the garbage is located on one side of the trash rack, which is inconvenient to clean. Utility Model Content

[0013] The beneficial effects of the utility model are:

[0014] 1. This anti-blocking trash rack has a V-shaped trash plate, which blocks floating objects. Under the impact of water flow, the floating objects float to both sides under the action of the V-shaped trash plate until they enter the interior of the trash storage box for collection. The output shaft of the hydraulic cylinder can lift the trash storage box and clean the floating objects inside the trash storage box. The hydraulic cylinder then lowers the trash storage box to its original position, thereby blocking and cleaning the floating objects. The water flow can pass through the bottom of the trash plate, which will not affect the flow of water flow and avoids the situation where floating objects are stuck on the trash rack, causing blockage and inconvenience in cleaning.

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is an anti-blocking trash rack, comprising two positioning plate columns 1, a V-shaped trash blocking plate 2 is arranged between the middle parts of the two positioning plate columns 1, the height of the trash blocking plate 2 is set higher than the water surface, and a cleaning mechanism 3 for cleaning the blocked impurities is arranged on the positioning plate column 1; the cleaning mechanism 3 comprises a hydraulic cylinder 4 vertically mounted on the positioning plate column 1, the bottom end of the hydraulic cylinder 4 is connected to a trash storage net box 6 via a connecting piece 5, and the trash blocking plate 2 blocks floating objects through the V-shaped trash blocking plate 2, and the trash blocking plate 2 is used to clean the impurities in the water flow. Under the impact, the floating objects float to both sides under the action of the V-shaped trash-blocking plate 2 until they enter the interior of the trash-storage net box 6 for collection. The output shaft of the hydraulic cylinder 4 can lift up the trash-storage net box 6 and clean the floating objects inside the trash-storage net box 6. The hydraulic cylinder 4 then lowers the trash-storage net box 6 to its original position to block and clean the floating objects. The water flow can pass through the bottom of the trash-blocking plate 2 without affecting the flow of the water flow, and also avoids the floating objects getting stuck on the trash rack, causing blockage and inconvenience in cleaning.

[0024] Among them, a sewage outlet 7 is provided at the bottom of the outer side of the sewage storage net box 6, and a pull-out cover 8 is provided at the sewage outlet 7. A U-shaped handle 9 is provided at the outer end of the pull-out cover 8. A limiting component 10 for limiting the pull-out cover 8 is provided on the sewage storage net box 6. The limiting component 10 includes a spring latch 11 arranged on the outer wall of the sewage storage net box 6. The pin rod of the spring latch 11 passes through the cavity formed by the handle 9 and the pull-out cover 8. When the floating objects inside the sewage storage net box 6 are discharged, the pin rod of the spring latch 11 is separated from the cavity formed by the handle 9 and the pull-out cover 8. By pulling the handle 9, the pull-out cover 8 can be separated from the sewage outlet 7, and the floating objects inside the sewage storage net box 6 can be discharged.

[0025] The connecting member 5 comprises a lifting connecting plate 12 arranged at the top opening of the sewage storage net box 6 , and the output shaft of the hydraulic cylinder 4 is connected to the lifting connecting plate 12 .

[0026] Among them, two vertical guide rails 13 are provided on one side of the positioning plate column 1, and a guide slider 14 matching the guide rails 13 is provided on the back of the sewage storage box 6. The guide slider 14 moves under the action of the guide rails 13, thereby improving the stability of the movement of the sewage storage box 6.

[0027] The interior of the sewage storage net box 6 is provided with a guide plate 15 inclined downward, and the lowest end of the guide plate 15 is connected to the sewage outlet 7 to facilitate the discharge of impurities such as floating objects collected inside the sewage storage net box 6.

[0028] When working, this anti-blocking trash rack has a V-shaped trash blocking plate 2, which blocks floating objects and, under the impact of water flow, makes the floating objects float to both sides under the action of the V-shaped trash blocking plate 2 until they enter the interior of the trash storage net box 6 for collection. The output shaft of the hydraulic cylinder 4 can lift up the trash storage net box 6 and clean the floating objects inside the trash storage net box 6. The hydraulic cylinder 4 then lowers the trash storage net box 6 to its original position, thereby completing the blocking and cleaning of the floating objects. The water flow can pass through the bottom of the trash blocking plate 2, will not affect the flow of the water flow, and also avoids the situation where the floating objects are stuck on the trash rack, causing blockage and inconvenience in cleaning.
