Description

Technical Field

[0001] This utility model relates to the field of drainage facilities technology, and in particular to a water grate for bridge engineering. Background Technology

[0002] In bridge engineering, road drainage differs from that of ordinary surface roads. Surface roads are usually built according to the terrain and can either drain directly through the terrain or introduce water into underground pipelines through drainage outlets. Bridge engineering requires specialized drainage systems, among which storm drains are an important component.

[0003] For example, Chinese patent CN221918954U, with an authorization announcement date of October 29, 2024, discloses a drainage grate for elevated and bridge roads, including a base and a drainage plate; the base includes a front wall, a rear wall, a left side wall, and a right side wall, which are connected sequentially and together define a cavity extending along the height direction; the front wall has multiple drainage outlets, each opening downwards at the bottom of the front wall; the height of the front wall is less than the height of the rear wall; the inner wall of the left side wall has a first support portion, and the inner wall of the right side wall has a second support portion; the drainage plate has multiple through grooves; the rear end of the drainage plate is rotatably connected to the top of the base, and at least a portion of the drainage plate is tilted backwards and upwards, allowing the drainage plate to switch between an open state and a closed state; when the drainage plate is in the closed state, the drainage plate covers the top of the cavity, and the left and right sides of the drainage plate press against the first and second support portions respectively; when the drainage plate is in the open state, the cavity is open.

[0004] During the use of water grates, debris such as stones, leaves, and garbage can accumulate inside, affecting the efficiency of rainwater drainage. Therefore, it is necessary to regularly open the drain plate for cleaning. However, in the aforementioned comparative patent, the base has a left and right side wall along its length, which obstructs cleaning (cleaning is done along multiple arranged water grates). Furthermore, the cover plate has left and right pins extending into left and right limiting holes at both ends. As shown in the accompanying drawings, the pins can move within the limiting holes, allowing the cover plate to move after installation. This movement can cause vibration and noise during vehicle travel due to road vibrations. Utility Model Content

[0005] The purpose of this invention is to provide a water grate for bridge engineering, which can improve cleaning efficiency and reduce noise generation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water grate for bridge engineering, comprising a base body and a cover plate disposed on the base body. The cross-section of the base body is U-shaped. The front wall of the base body is provided with strip-shaped drainage grooves with upward openings. One end of the base body is provided with a plug-in part, and the other end of the base body is provided with a plug-in groove. The plug-in parts and plug-in grooves of two adjacent water grates are matched to achieve assembly. The cover plate is provided with a plurality of strip-shaped drainage holes. Two hinge components are provided between the rear side of the cover plate and the rear wall of the base body to keep the cover plate fixed when fully opened. Two supports are provided at both ends of the front wall of the base body. The supports are provided with rubber seats with plug-in holes. The front ends of the cover plate are respectively provided with plug-in blocks for embedding into the plug-in holes of the rubber seats during the closing process.

[0007] By adopting the above technical solution, firstly, an upward-facing strip-shaped drainage groove is provided on the front wall of the base body, which facilitates the cleaning of the accumulated dirt in the strip-shaped drainage groove; secondly, the cross-section of the base body is U-shaped, which, when the cover is fully opened and kept in a fixed state, allows for unobstructed movement along the length of the water grate, thus facilitating the cleaning of debris in the side-by-side water grates; simultaneously, when the cover is closed, the plug on the cover inserts into the plug hole of the rubber seat, which on the one hand fixes the cover, and on the other hand allows the cover to rest on the two rubber seats, thereby reducing the noise generated at the cover.

[0008] A further feature of this invention is that: the rear wall of the base body has an extension extending toward the front wall; the rear wall of the base body has a hinge seat corresponding to the hinge assembly; the hinge assembly includes a connecting seat with a groove on the cover plate, a sliding shaft slidably connected in the groove of the connecting seat, and a hinge arm with one end on the sliding shaft and the other end hinged to the hinge seat; the hinge arm is L-shaped; when the cover plate is closed, the sliding shaft is in the middle of the groove; when the hinge arm rotates to the state of abutting the extension as the cover plate opens, and the cover plate rotates to a vertical state and moves downward to its limit state, the lower end of the cover plate rests on the hinge arm, and the side of the lower end of the cover plate near the extension abuts against the extension.

[0009] By adopting the above technical solution, the hinge assembly firstly includes a connecting seat with a groove on the cover plate, a sliding shaft slidably connected in the groove of the connecting seat, and a hinge arm with one end on the sliding shaft and the other end hinged to the hinge seat. This allows the position and angle of the sliding shaft at one end of the hinge arm and the cover plate to be adjusted, excluding the rotation angle of the hinge arm. Thus, when the hinge arm rotates to the state of abutting the extension as the cover plate opens, and the cover plate rotates to the vertical state and moves downward to its limit, the lower end of the cover plate rests on the hinge arm, and the side of the lower end of the cover plate near the extension abuts against the extension. At this time, when the connecting arm wants to rotate downward, the lower end of the cover plate is blocked by the extension, thus ensuring that the cover plate remains fixed when fully opened.

[0010] A further feature of this invention is that the end of the connecting seat near the front wall of the base body is provided with a mounting groove that communicates with the sliding groove and allows the sliding shaft to be embedded in the sliding groove.

[0011] By adopting the above technical solution, the sliding shaft can be embedded in the sliding groove for installation by setting the mounting groove.

[0012] A further feature of this invention is that the hinge base includes two hinge plates arranged side by side, the hinge plates being integrally disposed between the rear wall of the base body, the extension of the rear wall of the base body, and the bottom wall of the base body, and the two hinge plates and the hinge support arm are hinged together by a pin.

[0013] By adopting the above technical solution, the hinge plate is integrally set between the rear wall of the base body, the extension of the rear wall of the base body, and the bottom wall of the base body, thereby improving the structural strength of the base body, strengthening the structure at the hinge of the cover plate, and thus improving the overall structural stability.

[0014] A further feature of this invention is that the support is integrally disposed between the front wall of the base body and the bottom wall of the base body, the support is provided with a mounting hole, and the bottom of the rubber seat is provided with a mounting part that is inserted into the mounting hole, wherein the mounting part of the rubber seat is interference-fitted with the inner wall of the mounting hole.

[0015] By adopting the above technical solution, the support is integrated between the front wall and the bottom wall of the base body, thereby improving the structural strength of the base body and strengthening the structure at the cover plate support point, thus improving the overall structural stability.

[0016] A further feature of this invention is that the plug-in block is frustoconical in shape, and the cross-section of the plug-in block gradually decreases along the direction away from the cover plate.

[0017] By adopting the above technical solution, the plug block is truncated cone-shaped, and the cross-section of the plug block gradually decreases along the direction away from the cover plate, thereby facilitating the insertion of the plug block into the plug hole of the rubber seat.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example: A water grate for bridge engineering, such as Figure 1 As shown, it includes a base body 1 and a cover plate 2 disposed on the base body 1.

[0026] like Figure 1 and Figure 2 As shown, the cross-section of the base body 1 is "U" shaped. The front wall of the base body 1 is provided with strip-shaped drainage grooves 1-1 with the opening facing upward. One end of the base body 1 is provided with a plug-in part 1-2, and the other end of the base body 1 is provided with a plug-in groove 1-3. The plug-in parts 1-2 and plug-in grooves 1-3 of two adjacent water grates are matched to achieve assembly.

[0027] like Figures 2 to 4As shown, multiple strip-shaped drainage holes 2-1 are arranged on the cover plate 2. Two hinge components 3 are provided between the rear side of the cover plate 2 and the rear wall of the base body 1 to keep the cover plate 2 fixed when fully opened. The top of the rear wall of the base body 1 is provided with an extension 1-5 extending towards the front wall. The rear wall of the base body 1 is provided with a hinge seat 1-6 corresponding to the hinge component 3. The hinge component 3 includes a connecting seat 3-1 with a groove 3-1-1 on the cover plate 2, a sliding shaft 3-2 slidably connected in the groove 3-1-1 of the connecting seat 3-1, and a hinge arm 3-3 with one end on the sliding shaft 3-2 and the other end hinged to the hinge seat 1-6 by a pin. The hinge arm 3-3 is L-shaped. When the cover plate 2 is in the closed state, the sliding shaft 3-2 is in the middle of the slide groove 3-1-1; based on the state of the hinged support arm 3-3 rotating to the state of abutting the extension 1-5 during the opening process of the cover plate 2, when the cover plate 2 rotates to the vertical state and moves downward to the limit state, the lower end of the cover plate 2 rests on the hinged support arm 3-3, and the side of the lower end of the cover plate 2 near the extension 1-5 abuts against the extension 1-5.

[0028] like Figures 2 to 4 As shown, the connecting seat 3-1 has a mounting groove 3-1-2 at one end near the front wall of the base body 1, which communicates with the sliding groove 3-1-1 and allows the sliding shaft 3-2 to be embedded in the sliding groove. The hinge seat 1-6 includes two hinge plates 1-6-1 arranged side by side. The hinge plates 1-6-1 are integrally disposed between the rear wall of the base body 1, the extension 1-5 of the rear wall of the base body 1, and the bottom wall of the base body 1. The two hinge plates 1-6-1 and the hinge support arm 3-3 are hinged together by a pin.

[0029] like Figure 2 and Figure 5 As shown, two supports 1-4 are provided at both ends of the front wall of the base body 1. Each support 1-4 has a rubber seat 4 with a insertion hole 4-1. At both ends of the front side of the cover plate 2, insertion blocks 2-2 are respectively provided for embedding into the insertion holes 4-1 of the rubber seats 4 during the closing process. The supports 1-4 are integrally formed between the front wall and the bottom wall of the base body 1. Each support 1-4 has a mounting hole 1-4-1. The bottom of the rubber seat 4 has a mounting part 4-2 that inserts into the mounting hole 1-4-1, and the mounting part 4-2 of the rubber seat 4 is press-fitted with the inner wall of the mounting hole 1-4-1. The insertion block 2-2 is frustoconical in shape, and its cross-section gradually decreases in the direction away from the cover plate 2.

[0030] Implementation effect: First, the front wall of the base body 1 is provided with an upward-facing strip-shaped drainage groove 1-1, which facilitates the cleaning of the mud and dirt accumulated in the strip-shaped drainage groove; and the cross-section of the base body 1 is "U" shaped, which, when the cover plate 2 is fully opened and kept in a fixed state, allows for easy cleaning along the length of the water grate, thus facilitating the cleaning of debris in the side-by-side water grates; at the same time, when the cover plate 2 is closed, the plug 2-2 on the cover plate 2 is inserted into the plug hole 4-1 of the rubber seat 4, which on the one hand fixes the cover plate 2, and on the other hand allows the cover plate 2 to rest on the two rubber seats 4, thereby reducing the noise generated at the cover plate 2.

[0031] Firstly, the hinge assembly 3 includes a connecting seat 3-1 with a groove 3-1-1 mounted on the cover plate 2, a sliding shaft 3-2 slidably connected to the groove 3-1-1 of the connecting seat 3-1, and a hinge arm 3-3 with one end mounted on the sliding shaft 3-2 and the other end hinged to the hinge seat 1-6. This allows the position and angle of the sliding shaft 3-2 at one end of the hinge arm and the cover plate 2 to be adjusted, excluding the rotation angle of the hinge arm. Thus, when the hinge arm 3-3 rotates to the state of abutting the extension 1-5 during the opening process of the cover plate 2, and the cover plate 2 rotates to the vertical state and moves downward to its limit state, the lower end of the cover plate 2 rests on the hinge arm 3-3, and the side of the lower end of the cover plate 2 closest to the extension 1-5 abuts against the extension 1-5. At this time, when the connecting arm wants to rotate downward, the lower end of the cover plate 2 is blocked by the extension 1-5, thus ensuring that the cover plate 2 remains fixed when fully opened.

[0032] The sliding shaft 3-2 can be embedded in the sliding groove for installation by setting the mounting groove 3-1-2. The hinge plate 1-6-1 is integrally set between the rear wall of the base body 1, the extension 1-5 of the rear wall of the base body 1, and the bottom wall of the base body 1, thereby improving the structural strength of the base body 1, strengthening the structure at the hinge of the cover plate 2, and thus improving the overall structural stability. The first support 1-4 is integrally set between the front wall and the bottom wall of the base body 1, thereby improving the structural strength of the base body 1 and strengthening the structure at the support of the cover plate 2, thereby improving the overall structural stability. The insertion block 2-2 is frustoconical, and the cross-section of the insertion block 2-2 gradually decreases along the direction away from the cover plate 2, thereby facilitating the insertion of the insertion block 2-2 into the insertion hole 4-1 of the rubber seat 4.

[0033] 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.
