Description

Technical Field

[0001] This utility model relates to the field of drainage facilities technology, and in particular to a grating cover structure. Background Technology

[0002] Grille covers are installed on existing manholes, drainage ditches, and other facilities. The grille covers mainly serve the function of drainage. However, the following problems exist in the use of existing grille covers: (1) Odors from the manholes will overflow from the drainage holes of the covers; (2) Harmful insects will breed in the manholes and drainage ditches and then fly out. For example, chikungunya fever is mainly transmitted by Aedes aegypti and Aedes albopictus mosquitoes. Their larvae are easy to breed in various stagnant waters, including humid environments such as manholes and drainage ditches; (3) Fallen leaves are easy to fall into the manholes from the drainage holes and accumulate, thereby affecting the drainage efficiency of the manholes.

[0003] For example, an applicant has filed a grating cover structure (application publication number CN118065486A, application publication date May 24, 2024), which includes multiple support bars arranged in an arrangement, a connecting assembly for connecting the multiple support bars, and flexible sealing strips symmetrically arranged on the sides of any two adjacent support bars. The flexible sealing strip includes a fixed strip portion connected to the support bar and an arc-shaped piece portion integrally disposed on the fixed strip portion and bent downward in a direction away from the support bar; the ends of the arc-shaped pieces portions of the two flexible sealing strips between any two adjacent support bars abut against each other.

[0004] In the aforementioned comparative patent, the drainage holes on the grating cover are covered by the mutual contact of the arc-shaped pieces, thus solving problems such as odor overflow, the escape of harmful insects after breeding, and the accumulation of fallen leaves. However, the structure of its support strips and connecting components is relatively complex, which affects the production and assembly efficiency of the grating cover. Utility Model Content

[0005] The purpose of this utility model is to provide a grid cover structure that is easy to assemble.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a grid cover structure, comprising multiple base plates arranged in a row, multiple reinforcing plates arranged in a row and welded to the base plates in a direction perpendicular to the base plates, and a rubber layer wrapped and formed on the multiple base plates and multiple reinforcing plates; the portion of the rubber layer wrapping the reinforcing plates is a T-shaped reinforcing part, and insertion grooves extending along the length direction are formed on both sides of the reinforcing part, and flexible sealing strips are symmetrically arranged between any two adjacent insertion grooves of the reinforcing parts, the flexible sealing strips are arranged in an arc shape that bends downward away from the reinforcing part, and the two symmetrically arranged flexible sealing strips abut against each other on the side away from the support strip; an angled rubber block is provided at the end of the insertion groove between any two adjacent reinforcing parts to press down the ends of the two flexible sealing strips, the angled rubber block is provided with a guide slope to guide the fallen leaves between the two adjacent reinforcing parts and flexible sealing strips, and a separator portion is provided on the angled rubber block between the ends of the two flexible sealing strips.

[0007] By adopting the above technical solution, firstly, flexible sealing strips are symmetrically arranged between two adjacent reinforcing parts. The two symmetrically arranged flexible sealing strips abut against each other on the side away from the reinforcing part. This prevents odors from escaping, insects from flying out, and fallen leaves from falling in. When drainage is required, water can seep through the gap between the two flexible sealing strips or accelerate leakage after the flexible sealing strips are deformed. Secondly, the beveled rubber block facilitates sweeping out fallen leaves. The beveled rubber block presses down on the ends of the two flexible sealing strips, and the partition plate allows the ends of the flexible sealing strips to deform, avoiding the problem of one flexible sealing strip flipping up on the side away from the support strip and pressing down on the side of the other flexible sealing strip away from the support sleeve. In addition, in the welding arrangement of multiple base plates and reinforcing plates, rubber pads are wrapped and molded around the base plates and reinforcing plates. Subsequently, only the flexible sealing strips and beveled rubber blocks need to be inserted, which facilitates assembly. The rubber pads wrapping around the base plates and reinforcing plates prevent them from being corroded by external factors.

[0008] A further feature of this invention is that the reinforcing plate has multiple positioning slots arranged on it, and the base plate is embedded in the positioning slots of the multiple reinforcing plates and then fixed by welding.

[0009] By adopting the above technical solution, multiple positioning slots are arranged on the reinforcing sheet. The base plate is embedded in the positioning slots of the multiple reinforcing sheets and fixed by welding. This facilitates positioning when welding the base plate and the reinforcing sheet, improving the accuracy of the welded product. In addition, the combined structure of the base plate and the reinforcing sheet is grid-shaped, and the required size can be obtained by cutting the ends of the base plate or the reinforcing sheet, which facilitates processing.

[0010] A further feature of this invention is that the lower surface of the reinforcing sheet and the lower surface of the base plate are at the same height.

[0011] By adopting the above technical solution, the lower surface of the reinforcing plate and the lower surface of the base plate are at the same height. When placed on the well seat or drainage ditch, the contact area with the placement point is increased, thereby improving the structural stability of the grating cover structure after installation.

[0012] A further feature of this invention is that multiple anti-detachment posts are provided on both sides of the reinforcing plate, which are inclined toward the base plate.

[0013] By adopting the above technical solution, the setting of anti-detachment pillars during the rubber layer wrapping process can improve the firmness of the bond between the rubber layer and the reinforcing sheet. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example: A grid cover structure, such as Figures 1 to 3 As shown, it includes multiple base plates 1 arranged in an array, multiple reinforcing sheets 2 arranged in an array and welded to the base plates 1 in a direction perpendicular to the base plates 1, and a rubber layer 3 wrapped and molded on the multiple base plates 1 and the multiple reinforcing sheets 2.

[0021] like Figure 2 and Figure 3 As shown, multiple positioning slots 21 are arranged on the reinforcing plate 2, and the base plate 1 is embedded in the positioning slots 21 of the reinforcing plate 2 and fixed by welding. The lower surface of the reinforcing plate 2 and the lower surface of the base plate 1 are at the same height. Multiple anti-detachment posts 22 are provided on both sides of the reinforcing plate 2, which are inclined towards the base plate 1.

[0022] like Figure 1 and Figure 2 As shown, the part of the rubber layer 3 that wraps the reinforcing sheet 2 is a T-shaped reinforcing part 31. Insertion grooves 32 extending along the length direction are formed on both sides of the reinforcing part 31. Flexible sealing strips 4 are symmetrically arranged between the insertion grooves 32 of any two adjacent reinforcing parts 31. The flexible sealing strips 4 are arranged in an arc shape that bends downward in the direction away from the reinforcing part 31. The two symmetrically arranged flexible sealing strips 4 abut against each other on the side away from the support strip.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, an angled rubber block 5 is provided at the end of the insertion groove 32 between any two adjacent reinforcing parts 31 to press down the ends of the two flexible sealing strips 4. The angled rubber block 5 is provided with a guide slope 51 to guide the fallen leaves swept out between the two adjacent reinforcing parts 31 and the flexible sealing strips 4. The angled rubber block 5 is provided with a partition piece 52 located between the ends of the two flexible sealing strips 4.

[0024] Implementation Effects: Firstly, flexible sealing strips 4 are symmetrically arranged between two adjacent reinforcing parts 31. The two symmetrically arranged flexible sealing strips 4 abut against each other on the side away from the reinforcing part 31, which prevents odors from escaping, insects from flying out, and fallen leaves from falling in. When drainage is required, water can seep through the gap between the two flexible sealing strips 4 or the flexible sealing strips 4 can be deformed to accelerate leakage. Secondly, the angled rubber block 5 facilitates the sweeping out of fallen leaves, and the angled rubber block 5 presses down on the ends of the two flexible sealing strips 4 and the separating piece 52. The design allows the end of the flexible sealing strip 4 to deform, preventing one flexible sealing strip 4 from flipping up and pressing against the other flexible sealing strip 4 on the side away from the support sleeve. In addition, the rubber pad is molded and placed around the base plate 1 and the reinforcing plate 2 during welding. This allows for easy assembly, as only the flexible sealing strip 4 and the angled rubber block 5 need to be inserted. The rubber pad also prevents the base plate 1 and the reinforcing plate 2 from being corroded by external factors.

[0025] Multiple positioning slots 21 are arranged on the reinforcing plate 2. The base plate 1 is embedded in the positioning slots 21 of the reinforcing plate 2 and fixed by welding, which facilitates positioning during the welding of the base plate 1 and the reinforcing plate 2, improving the accuracy of the welded product. In addition, the combined structure of the base plate 1 and the reinforcing plate 2 is grid-like, and the required size can be obtained by cutting the ends of the base plate 1 or the reinforcing plate 2, which facilitates processing. The lower surface of the reinforcing plate 2 and the lower surface of the base plate 1 are at the same height. When placed on the well seat or drainage ditch, the contact area with the resting place is increased, improving the structural stability of the grating cover structure after installation. During the molding process of the rubber layer 3, the anti-detachment post 22 can improve the firmness of the bond between the rubber layer 3 and the reinforcing plate 2.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
