Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a novel sewage interception mechanism for municipal drainage. Background Art

[0002] Municipal drainage refers to the process in which rainwater and sewage in a city are collected and discharged into water bodies such as rivers, lakes, and reservoirs through facilities such as sewers, drains, and rainwater outlets. In this process, the sewage needs to be treated to meet the discharge standards or the purpose of reuse. The sewage interception mechanism is a device in the municipal drainage system, which is mainly used to collect and treat sewage. In combination with the existing literature, a sewage interception device for municipal drainage (CN209837256U) includes a well seat and a cover body, and the cover body is hinged on the well seat. It also includes a filter screen, a linkage mechanism, and a through hole. The through hole is opened on the side wall of the well seat, and the hinge points of the through hole and the cover body are both arranged on the same side of the well seat. The filter screen passes through the through hole and is slidably connected to the inner wall of the well seat. The sewage interception device for municipal drainage, through the provided filter screen, spring, concave slide, and connecting rod, cooperates with each other, so that personnel do not need to perform cleaning operations in such a small place as the well, and do not need to take out the filter screen deliberately. By driving the slider and the connecting rod to move during the process of opening the cover, the filter screen moves out of the well seat through the through hole, which reduces the number of cleaning steps, shortens the cleaning time, and improves the cleaning efficiency. It can be seen that at least the following defects are exposed during use:

[0003] 1. During the use of the sewage interception mechanism of the current municipal drainage, the water is simply filtered through the filter net before drainage. Since there are some sediment particles and other substances in the water, the filter net can only filter some large and medium-sized substances, so that small substances such as sediment particles will be discharged with the water flow. Over time, a layer of sediment will accumulate at the bottom of the sewage interception mechanism of the municipal drainage. The current sediment cleaning is done manually. Due to the low efficiency of manual cleaning, the cleaning efficiency of the sewage interception mechanism of the municipal drainage is affected.

[0004] 2. During the inspection and maintenance of the sewage interception mechanism of today's municipal drainage, since most of the filter screens of today's municipal drainage sewage interception mechanism are fixed inside the sewage interception mechanism of the municipal drainage by screws, special tools need to be prepared for maintenance and replacement when the filter screen is repaired and replaced. Utility Model Content

[0005] The purpose of the utility model is to provide a novel sewage interception mechanism for municipal drainage, so as to solve the problems in the use of the existing novel sewage interception mechanism for municipal drainage proposed in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A novel sewage interception mechanism for municipal drainage comprises a main body and a connecting block, a shielding box is fixedly installed at the front end of the main body, a first telescopic rod is fixedly installed at the upper end of the shielding box, a limiting plate is connected inside the shielding box, a limiting plate is fixedly installed at the lower end of the first telescopic rod, a second telescopic rod is installed at the rear end of the main body, and a push plate is arranged inside the main body; two protrusions are installed at the front and rear ends of the connecting block, a fixed block is connected inside the protrusion, a pull strip is installed at the front end of the fixed block, and four slots are arranged inside the main body.

[0008] Preferably, water outlets are provided at the left and right ends of the main body, and two second handles are installed at the upper end of the connecting block.

[0009] Preferably, a cover is provided inside the upper end of the main body and a plurality of holes are provided inside the cover, and two first handles are installed on the upper end of the cover.

[0010] Preferably, the shielding box is arranged in an L shape.

[0011] Preferably, the size of the slot matches the protrusion, the connecting block is connected to the main body by inserting the protrusion into the slot, and the protrusion and the slot are arranged in a T shape.

[0012] Preferably, the push plate is fixedly connected to the telescopic part of the second telescopic rod.

[0013] Preferably, connecting grooves are arranged inside the protrusion, the connecting block and the filter net. The connecting grooves of the protrusion and the connecting block are through-going, while the connecting groove of the filter net is not through-going. The connecting block is inserted into the three connecting grooves through a fixing block to connect with the filter net.

[0014] The utility model provides a novel sewage interception mechanism for municipal drainage, which has the following beneficial effects:

[0015] 1. By setting the first telescopic rod, the second telescopic rod, the limit plate, the push plate and the shielding box, when the inside of the main body needs to be cleaned, it is only necessary to start the first telescopic rod and the second telescopic rod with the push plate to clean the mud and sand accumulated inside the main body, thereby improving the cleaning efficiency of the sewage interception mechanism of the municipal drainage.

[0016] 2. By setting the protrusion, fixed block, pull bar, slot and connecting block, when the filter needs to be repaired or replaced, it is only necessary to slide the protrusion out of the slot and then pull out the fixed block to repair or replace the filter, so that the filter can be replaced without preparing special tools.

When it is necessary to clean the mud and sand inside the main body 1, start the first telescopic rod 4 to drive the limit plate 13 to move upward, and then start the second telescopic rod 6 to control the push plate 12 to move forward, and push the mud and sand inside the main body 1 into the shielding box 5 to discharge it, thereby improving the cleaning efficiency of the sewage interception mechanism of the municipal drainage. Four slots 8 are arranged inside the main body 1, and the inside of the main body 1 is connected to the connecting block 9 through a protrusion 10.

[0026] like Figure 4-5 As shown, a filter screen 14 is connected to the interior of the connecting block 9, and two second handles 11 are installed at the upper end of the connecting block 9. The connecting block 9 is pulled by the second handles 11. Two protrusions 10 are installed at the front and rear ends of the connecting block 9, and connecting grooves 17 are arranged inside the connecting block 9, the protrusions 10, and the filter screen 14. The connecting grooves 17 of the connecting block 9 and the protrusions 10 are set through, and the connecting grooves 17 of the filter screen 14 are not set through. The connecting block 9 is connected to the filter screen 14 by inserting the fixing block 16 into the three connecting grooves 17.

[0027] Working principle: water flows into the main body 1 through the cover 2, and then filters the water through the filter 14. The filtered water is discharged through the water outlets 7 at both ends of the main body 1. When it is necessary to clean the mud and sand inside the main body 1, start the first telescopic rod 4 to drive the limit plate 13 to move upward, and start the second telescopic rod 6 to control the push plate 12 to move forward, so as to push the mud and sand inside the main body 1 into the shielding box 5 to discharge it, thereby improving the cleaning efficiency of the sewage interception mechanism of the municipal drainage. When it is necessary to repair and replace the filter 14, it is only necessary to pull the protrusion 10 out of the slot 8, and then pull the pull rod 15 to drive the fixing block 16 to be pulled out from the filter 14, the connecting block 9, and the protrusion 10, and then take the filter 14 out of the connecting block 9, so as to repair and replace the filter 14. Therefore, no special tools are required to replace the filter 14.
