Description

Technical Field

[0001] The utility model relates to the technical field of drainage facilities, and particularly relates to an odor-proof rainwater grate.

Background Art

[0002] Rainwater grates are generally arranged beside the road (i.e., at the edge of the road), and are drainage facilities used to divert rainwater on the road into the sewer.

[0003] Rainwater grates generally include a frame body and a grid cover plate assembled on the frame body. At the same time, in order to facilitate the interception and cleaning of impurities in rainwater, some rainwater grates are also equipped with a dirt intercepting net. For example, a rainwater grate structure for facilitating the cleaning of sundries disclosed in the Chinese utility model patent with the application number CN202322700173.1 includes a base installed at the rainwater inlet, a through hole communicating with the rainwater inlet is provided on the base, a grate cover capable of covering the through hole is provided on the base, a water inlet is provided on the grate cover, and a dirt intercepting net is installed in the through hole of the base; a limiting block is arranged on the inner wall of the through hole along the circumferential direction of the through hole, and a limiting plate capable of cooperating with the limiting block is installed around the dirt intercepting net. However, the existing rainwater grates generally do not have an odor-proof function, resulting in the easy diffusion of the odor in the sewer to the road surface. At the same time, there is usually a large amount of sediment in rainwater, and it is difficult for the dirt intercepting net to effectively intercept the sediment, resulting in the possible blockage of the sewer due to sediment accumulation. In view of the above problems, the inventor of this case conducted in-depth research on this problem, and thus this case was born.

Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an odor-proof rainwater grate to solve the problems that the odor in the existing rainwater grate is easy to diffuse to the road surface and the sewer may be blocked due to sediment accumulation.

[0005] The utility model is realized as follows: an odor-proof rainwater grate, including a frame body, a sand storage box, a drain pipe, and a water passing cover plate installed on the frame body; the sand storage box is detachably arranged in the frame body, and the sand storage box is located below the water passing cover plate; the upper end of the drain pipe passes through the bottom of the sand storage box and extends upward to form an extension section, and the lower end of the drain pipe forms a bent pipe part for realizing odor prevention.

[0006] Further, it also includes a baffle; the bent pipe part has an upward-facing water outlet opening, the baffle is hinged to the bent pipe part, and the baffle blocks the water outlet opening under the action of gravity.

[0007] Further, a filter cover is arranged at the upper end of the extension section.

[0008] Further, an external thread section is formed at the upper end of the extension section, and an internal thread is formed on the inner wall of the filter cover. The filter cover is screwed onto the upper end of the extension section through the cooperation of the internal thread and the external thread section.

[0009] Further, a limiting convex ring is arranged around the circumference at the lower end position of the extension section corresponding to the external thread section, and the sand holding box is clamped by the cooperation of the limiting convex ring and the filter cover.

[0010] Further, the top of the filter cover is a hollow structure, and anti-slip strips are arranged on the outer side wall of the filter cover.

[0011] Further, a hinge seat is arranged at the bent position on the outer wall of the elbow section, an articulated portion is arranged at the outer edge of the baffle, and the articulated portion is articulated with the hinge seat through a hinge shaft.

[0012] Further, a cavity is formed through the upper and lower parts of the frame body, a supporting step is formed on the side wall of the cavity, and the water passing cover plate is installed on the supporting step; a plurality of supporting sinking grooves are sunken on the step surface of the supporting step, and a supporting block is arranged at the upper end of the sand holding box corresponding to each supporting sinking groove, and the sand holding box is detachably supported on the supporting sinking groove through the supporting block.

[0013] Further, the top surface of the frame body is an arc surface with high sides and low middle, and the water passing cover plate is an arc structure with high sides and low middle.

[0014] Further, a plurality of water inlet slots are arranged at intervals along the length direction and penetrate through the water passing cover plate, and each water inlet slot extends from the middle to both sides along the width direction; at least one communication notch communicated with the water inlet slot is arranged on both sides of the water passing cover plate, and the communication notches on both sides of the water passing cover plate are arranged staggeredly.

[0015] By adopting the technical scheme of the present utility model, at least the following beneficial effects are achieved:

[0016] 1. A sand holding box is detachably arranged in the frame body, and the upper end of the drain pipe passes through the bottom of the sand holding box and extends upward to form an extension section. When in specific use, most of the rainwater flowing in from the water passing cover plate will first enter the sand holding box, so that the sediment in the rainwater will precipitate and stay at the inner bottom of the sand holding box. As the water level in the sand holding box rises, the water filtered by precipitation can be drained away through the drain pipe, thereby reducing the blockage of the sewer caused by sediment accumulation and facilitating the disassembly and cleaning of the sand holding box.

[0017] 2. A bent pipe portion is formed at the lower end of the drain pipe. During actual use, a part of the rainwater will be retained inside the bent pipe portion, which can, to a certain extent, prevent the odor in the sewer from spreading to the road surface, thus achieving a certain anti-odor effect.

[0018] 3. By designing that the bent pipe portion has a water outlet opening arranged upward and is provided with a baffle for the water outlet opening, during actual use, when the water inside the bent pipe portion dries up and loses the anti-odor effect, the baffle can block the water outlet opening under the action of gravity, enabling the baffle to replace the dried-up water and play an anti-odor role. Therefore, through the cooperation of the bent pipe portion and the baffle, a good anti-odor effect can be achieved; at the same time, when drainage is required, the baffle will lift upward under the action of the water flow impact force, ensuring normal drainage function.

[0019] 4. By designing that the upper end of the extension section has an external thread section, the filter cover has an internal thread, and a limiting convex ring is arranged at the lower end of the external thread section. During actual use, on the one hand, the limiting convex ring can cooperate with the filter cover to clamp the sand holding box, so as to limit the upper end of the drain pipe inside the sand holding box and prevent sediment from falling through the gap between the drain pipe and the bottom of the sand holding box; on the other hand, it is convenient to disassemble and clean the sand holding box.

Among them, both the frame body 1 and the water passing cover plate 4 can be made of ductile iron, the drain pipe 3 can be made of plastic pipe, and the sand box 2 can be made of iron box; the sand box 2 is detachably arranged in the frame body 1 to facilitate the disassembly and cleaning of the sand box 2, and the sand box 2 is located below the water passing cover plate 4; the upper end of the drain pipe 3 passes through the bottom of the sand box 2 and extends upward to form an extension section 32, so that the sediment in the rainwater can precipitate and stay at the inner bottom of the sand box 2, and the lower end of the drain pipe 3 forms a bent pipe part 31 for preventing stink.

[0041] By adopting the above technical solutions of the present utility model, there are at least the following beneficial effects:

[0042] 1. A sand box 2 is detachably arranged in the frame body 1, and the upper end of the drain pipe 3 passes through the bottom of the sand box 2 and extends upward to form an extension section 32. When in use, most of the rainwater flowing in from the water passing cover plate 4 will first enter the sand box 2, so that the sediment in the rainwater will precipitate and stay at the inner bottom of the sand box 2. As the water level in the sand box 2 rises, the water filtered by precipitation can be drained away through the drain pipe 3, thus reducing the blockage of the sewer caused by sediment accumulation, and at the same time facilitating the disassembly and cleaning of the sand box 2.

[0043] 2. A bent pipe part 31 is formed at the lower end of the drain pipe 3, so that during the specific use process, a part of the rainwater will stay inside the bent pipe part 31, which can prevent the odor in the sewer from diffusing to the road surface to a certain extent, thus playing a certain stink-proof effect.

[0044] In some embodiments of the present utility model, the stink-proof rainwater grate 100 further includes a baffle 5; the bent pipe part 31 has an upwardly arranged water outlet opening 311, the baffle 5 is hinged to the bent pipe part 31, and the baffle 5 blocks the water outlet opening 311 under the action of gravity.

[0045] The present utility model designs that the bent pipe part 31 has an upwardly arranged water outlet opening 311 and is provided with a baffle 5 for the water outlet opening 311. During the specific use process, when the water inside the bent pipe part 31 dries up and loses the stink-proof effect, the baffle 5 can block the water outlet opening 311 under the action of gravity, so that the baffle 5 can replace the dried-up water to play a stink-proof role. Therefore, through the cooperation of the bent pipe part 31 and the baffle 5, a good stink-proof effect can be achieved; at the same time, when drainage is required, the baffle 5 will be lifted upward under the action of the water flow impact force, ensuring the normal drainage function.

[0046] In some embodiments of the present utility model, a filter cover 6 is provided at the upper end of the extension section 32. The filter cover 6 can filter larger floating objects (such as leaves) in the rainwater, preventing the large floating objects from entering the drain pipe 3.

[0047] Furthermore, an external thread section 321 is formed at the upper end of the extension section 32, and an internal thread 61 is formed on the inner wall of the filter cover 6. The filter cover 6 is screwed onto the upper end of the extension section 32 by the cooperation of the internal thread 61 and the external thread section 321.

[0048] Furthermore, a limiting convex ring 322 is circumferentially arranged around the extension section 32 at the lower end position corresponding to the external thread section 321, and the sand box 2 is clamped by the cooperation of the limiting convex ring 322 and the filter cover 6.

[0049] In the present utility model, by designing that the upper end of the extension section 32 has an external thread section 321, the filter cover 6 has an internal thread 61, and a limiting convex ring 322 is arranged at the lower end of the external thread section 321, when in specific use, on one hand, the limiting convex ring 322 and the filter cover 6 can be used to clamp the sand box 2 together, so as to limit the upper end of the drain pipe 3 in the sand box 2 and prevent sediment from falling through the gap between the drain pipe 3 and the bottom of the sand box 2; on the other hand, it is convenient to disassemble and clean the sand box 2.

[0050] In the present utility model, the top of the filter cover 6 is a hollow structure 62, allowing rainwater to enter the drain pipe 3 through the top of the filter cover 6, while also playing a certain filtering role; anti-slip strips 63 are provided on the outer side wall of the filter cover 6 to facilitate the rotation operation of the filter cover 6.

[0051] In some embodiments of the present utility model, in order to better hinge the baffle 5 with the elbow part 31, a hinge seat 312 is provided at the bent position on the outer wall of the elbow part 31, a hinge part 51 is provided on the outer edge of the baffle 5, and the hinge part 51 is hinged to the hinge seat 312 through a hinge shaft (not shown).

[0052] In some embodiments of the present utility model, an inner cavity 11 is formed through the upper and lower parts of the frame body 1. A support step 12 is formed on the side wall of the inner cavity 11. The water-passing cover plate 4 is installed on the support step 12. The support step 12 is used to meet the support requirement for the water-passing cover plate 4 and prevent the water-passing cover plate 4 from protruding above the frame body 1. A plurality of support sinking grooves 121 are sunken on the step surface of the support step 12. At the upper end of the sand box 2, a support block 21 is provided corresponding to each support sinking groove 121. The sand box 2 is detachably supported on the support sinking groove 121 through the support block 21, which can not only meet the support requirement for the sand box 2 but also facilitate the disassembly of the sand box 2. As a specific implementation manner of the present utility model, the frame body 1, the water-passing cover plate 4, and the sand box 2 are all in a rectangular structure, and support blocks 21 are provided on all four sides of the sand box 2. Support sinking grooves 121 are formed on the step surface of the support step 12 corresponding to each support block 21.

[0053] In some embodiments of the present utility model, the top surface of the frame body 1 is an arc surface that is high on both sides and low in the middle. The water-passing cover plate 4 is in an arc structure that is high on both sides and low in the middle. By adopting the above structural design, when in use, rainwater can flow quickly from both sides of the water-passing cover plate 4 to the middle, gather and drain downward, so as to achieve a better drainage effect and reduce the water accumulation on the road surface.

[0054] In some embodiments of the present utility model, a plurality of water inlet slots 41 are arranged at intervals and penetrate along the length direction on the water-passing cover plate 4. Each water inlet slot 41 extends from the middle to both sides along the width direction and does not extend to the side walls on both sides of the water-passing cover plate 4. In this way, when rainwater flows from both sides of the water-passing cover plate 4 to the middle and gathers, it can also drain downward through the water inlet slots 41 continuously, so as to achieve a better drainage effect. At least one communication notch 42 communicating with the water inlet slots 41 is provided on both sides of the water-passing cover plate 4, and the communication notches 42 on both sides of the water-passing cover plate 4 are arranged staggeredly to ensure that the water-passing cover plate 4 is an integral body. When the present utility model is specifically implemented, usually 1-2 communication notches 42 are arranged on each side of the water-passing cover plate 4, and it is not appropriate to arrange too many communication notches 42, otherwise the strength of the entire water-passing cover plate 4 cannot be guaranteed. By adopting the above structural design, not only can the overall support strength of the water-passing cover plate 4 be ensured, but also the communication notch 22 can be used to make the water-passing cover plate 4 generate elastic deformation, so as to realize the more tight and reliable assembly of the water-passing cover plate 4 and the frame body 1, and the disassembly and assembly operation of the water-passing cover plate 4 is also very convenient.

[0055] In the specific implementation of the present utility model, one end of the water passing cover plate 4 is provided with an assembly block 43, and plug-in grooves 44 are formed on the side walls on both sides of the assembly block 43; an assembly sunk groove 13 is formed on the frame body 1 at a position corresponding to the assembly block 43, and plug-in protrusions 14 are formed on the side wall of the assembly sunk groove 13 corresponding to each plug-in groove 44. The assembly block 43 is assembled with the plug-in protrusion 14 through the plug-in groove 44, so as to realize the assembly of one end of the water passing cover plate 4 and one end of the frame body 1. It should be noted that the assembly block 43 and the plug-in protrusion 14 are rotatably connected, so that the water passing cover plate 4 can be rotated during the disassembly and assembly process. As a specific implementation manner of the present utility model, two assembly blocks 43 are arranged at intervals in the middle of one end of the water passing cover plate 4, and two assembly sunk grooves 13 are correspondingly arranged at one end of the frame body 1.

[0056] An assembly clamping block 45 is arranged at the bottom of the other end of the water passing cover plate 4, and an assembly clamping groove 15 is formed on the side wall of the inner cavity 11 at a position corresponding to the assembly clamping block 45, and the assembly clamping groove 15 is located below the support step 12. The assembly clamping block 45 is clamped in the assembly clamping groove 15, so as to realize the clamping connection of the other end of the water passing cover plate 4 and the other end of the frame body 1; an operation notch 46 is formed at the top of the other end of the water passing cover plate 4 to facilitate using the operation notch 46 to pry the water passing cover plate 4 to generate elastic deformation. As a specific implementation manner of the present utility model, two assembly clamping blocks 45 are arranged at intervals at the bottom of the other end of the water passing cover plate 4, and two assembly clamping grooves 15 are correspondingly arranged on the side wall of the inner cavity 11.

[0057] Although the specific implementation manners of the present utility model are described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present utility model should be covered by the scope protected by the claims of the present utility model.
