Description

Technical Field

[0001] This utility model relates to the field of steel grating technology, specifically to a drainage ditch steel grating that is easy to clean. Background Technology

[0002] Steel grating is a drainage component made of steel. Most of them are rectangular in shape and are composed of crisscrossing metal partitions inside, forming multiple drainage ditches. During the rainy season, it can isolate external garbage and collect sewage flowing in from various places into the sewer for centralized treatment, preventing drainage pipe blockage.

[0003] Traditional steel gratings only have the ability to trap water, but lack a closing function. In the event of a long drought and no need for drainage, debris may pass through the trough and enter the sewer. If not cleaned in time, it can easily cause blockages, and the maintenance cost is relatively high, making it difficult to keep the water flow unobstructed.

[0004] Now, a new type of easy-to-clean steel grating for drainage ditches is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage ditch steel grating that is easy to clean, so as to solve the problem of inconvenience in opening and closing mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage ditch steel grating that is easy to clean, comprising a main body and seepage grooves. Five sets of seepage grooves are arranged between the front and rear of the main body. A left fixing block is fixed to the left rear of the bottom of the main body, and a right fixing block is fixed to the right rear of the bottom of the main body. A screw rod is laterally movably connected between the left and right fixing blocks. A baffle is threaded to the outside of the screw rod, and a threaded groove is provided between the two sides of the rear of the baffle. Limiting grooves are fixed between the rear and front sides of the bottom of the main body. A gear one is movably connected to the right side of the right fixing block, and a gear two is movably connected to the right rear of the bottom of the main body. A slot is provided at the right rear of the main body, and a handle is movably connected to the lower part of the slot. A hidden groove is provided at the upper left of the slot, and a stop block is movably connected in the hidden groove.

[0007] Preferably, the first gear meshes with the lower left corner of the second gear, and the top of the second gear is fixed to the handle.

[0008] Preferably, the motherboard body has a connecting groove at each of the four corners, and a slot at the bottom of the connecting groove. A limit rod is inserted and fixed in the slot, and a pin is fixed above the limit rod.

[0009] Preferably, the limiting rods are symmetrically fixed on both sides of the bottom of the pin, and the pin spans between adjacent main body panels.

[0010] Preferably, a rectangular groove is provided on the right side of the seepage groove, and a sliding groove is provided at the front end and the rear end of the rectangular groove. A slider is movably connected in the sliding groove, and a filter is fixed at the center between the inner sides of the slider. A connecting rod is fixed between the outer sides of the slider. A transverse groove is provided at the front and the rear of the main body.

[0011] Preferably, the connecting rod is embedded in the horizontal groove, and the seepage groove is connected to the rectangular groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-clean drainage ditch steel grating not only realizes the timely closure or opening of the seepage channel and the maintenance of the stability of adjacent gratings, but also makes it easy to intercept small debris;

[0013] (1) A screw rod is laterally connected between the left fixed block and the right fixed block. The stop block is pushed horizontally towards the hidden groove above the slot, so that the handle is exposed. After rotating the handle, the gear two connected at the bottom is rotated, thereby pushing the gear one meshing on the left side. The screw rod is rotated between the left fixed block and the right fixed block. Under the restriction of the front and rear limit grooves, the baffle is pushed horizontally to cover the seepage groove, or the baffle is removed so that the seepage groove is exposed in time.

[0014] (2) By inserting and fixing the limiting rod in the slot longitudinally, aligning the adjacent motherboard body, the left and right connecting slots are assembled together. Then, insert the pin longitudinally so that the limiting rod at the bottom of the pin is embedded in the slot. This can reinforce the adjacent motherboard bodies from both the front and back, prevent the motherboard bodies from loosening under the scouring of rainwater, improve the connection strength between the motherboard bodies, and facilitate disassembly or reinstallation.

[0015] (3) By fixing the filter at the center between the inner sides of the slider, the connecting rod moves left and right along the front and rear horizontal grooves of the main body, passes through the front and rear sliding grooves, and adjusts the left and right position of the filter by the slider, so that it passes through the rectangular groove and enters the seepage tank for blocking. It can be used to intercept small debris and prevent it from flowing into the sewer with rainwater. It can also be collected in the rectangular groove to speed up the flow of sewage. It can be judged by the real-time water flow. Attached Figure Description
