Description

Technical Field

[0001] This utility model belongs to the field of road infrastructure technology, and in particular relates to an anti-displacement ductile iron water grate. Background Technology

[0002] Water grates are mainly installed at the opening of deep wells to prevent pedestrians from falling into them. Water grates are an essential road facility in municipal construction and are commonly used in drainage systems.

[0003] An existing application (application number 202020257094.1) discloses a self-locking curved ductile iron grate for a drainage channel, comprising a grate and a base. The grate includes a back plate with evenly distributed curved drainage holes. A first frame is fixedly connected to the edge of the back plate. Three limit blocks are fixedly connected to one end of the first frame. Trip shafts are fixedly connected to one end of the limit blocks on both sides of the first frame. Two impact grooves are provided at the other end of the first frame. An elastic break is provided on the same side of the back plate and the first frame as the trip shaft. The base includes a second frame. In this invention, the grate has breaks on both sides, forming a transverse spring frame. Utilizing the elasticity of ductile iron, triangular impact points are designed at one longitudinal end of the grate and the grate base. The other longitudinal end of the grate abuts against the inner edge of the base. The two sides have built-in trip shafts to restrict the grate from lifting, thereby achieving a self-locking function, preventing displacement, jumping, and arbitrary opening.

[0004] During use, existing water grates are prone to popping up under the pressure of heavy objects such as vehicles moving at high speeds. This can cause them to shift in position, leading to the opening being exposed and potentially causing them to fall off. Utility Model Content

[0005] This invention provides a displacement-resistant ductile iron water grate, aiming to solve the problem of positional displacement in existing water grates.

[0006] This utility model is implemented as follows: a displacement-resistant ductile iron water grate includes a sewer opening, a through groove is provided inside the center of the sewer opening, an installation groove is provided inside the top center of the sewer opening, a positioning frame is installed on the inner wall of the installation groove, a water grate outer frame is installed at the center of the installation groove, a water grate drain plate is slidably connected inside the center of the water grate outer frame, and rotating heads are installed on the four sides of the bottom of the water grate drain plate away from the center, with positioning brackets installed at the bottom of the rotating heads.

[0007] The outer surface of the drain plate of the grate is in close contact with the inner surface of the inner wall of the outer frame of the grate.

[0008] Preferably, the four sides of the outer frame of the grate near the center of the sewer opening are provided with limiting grooves. A limiting rod is fixed at the center of the limiting groove. A high-pressure spring is sleeved on the outside of the limiting rod. A lower return pad is fixed on the top of the high-pressure spring. An upper return pad is installed on the top of the lower return pad. A limiting block is installed on the top of the upper return pad.

[0009] Preferably, the limiting rod passes through the interior of the lower rebound pad, the upper rebound pad, and the limiting block, respectively, and the side of the limiting block near the center of the sewer opening is fixedly connected to the outer surface of the drain grate.

[0010] Preferably, the hardness of the upper rebound pad is less than that of the lower rebound pad, and the high-pressure spring is a coarse spring with greater pressure resistance.

[0011] Preferably, positioning claws are evenly distributed on the bottom side of the positioning frame away from the center of the sewer opening, and spherical buckles are fixed at both ends of the positioning frame near the center of the sewer opening. A pusher frame is rotatably connected to the spherical buckle near the center of the sewer opening, and a connecting buckle is rotatably connected to the top of the pusher frame.

[0012] Preferably, an adjustment bracket is fixed to the top of the connecting buckle, an adjustment screw is threadedly connected to the center of the adjustment bracket, an adjustment buckle is fixed to the top of the adjustment screw, and an installation groove is opened inside the center of the top of the water grate plate, with a sealing cap rotatably connected to the top of the installation groove.

[0013] Preferably, an insert is fixed to the lower part of the top of the adjusting screw, and the adjusting screw passes through the interior of the center of the water grate plate.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages:

[0015] 1. This utility model, through the setting of positioning frame and limiting groove, causes the water grate plate to press down and bounce up when the top of the water grate plate is subjected to high pressure and moves quickly. When it bounces up, the positioning frame can limit the height of the bounce, preventing it from bouncing up too high and causing dislocation. At the same time, the high pressure spring installed in the limiting groove, together with the lower and upper return spring pads, can buffer the downward pressure, thereby reducing the upward bounce force and providing double anti-dislocation protection.

[0016] 2. This utility model, through the setting of positioning frame and positioning claw, allows the drain grate plate to be installed in the installation groove. By rotating the adjusting screw, the position of the adjusting frame is lowered, and the adjusting frame drives the pushing frame to expand. This causes the positioning claw to move away from the center of the sewer opening, allowing the positioning claw to penetrate deeply into the inner wall of the inlet groove, further reinforcing the connection between the drain grate plate and the sewer opening and preventing detachment.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model embodiment provides a displacement-resistant ductile iron water grate, such as... Figure 1-5As shown, the device includes a drain outlet 1, with a through groove in the center of the drain outlet 1 and an installation groove in the center of the top of the drain outlet 1. A positioning frame 2 is installed on the inner wall of the installation groove, and a grate outer frame 3 is installed in the center of the installation groove. A grate drain plate 6 is slidably connected to the center of the grate outer frame 3. Rotating heads 4 are installed on the four sides of the bottom of the grate drain plate 6 away from the center, and positioning brackets 5 are installed at the bottom of the rotating heads 4. The outer surface of the grate drain plate 6 is in close contact with the inner surface of the inner wall of the grate outer frame 3.

[0026] It should be noted that, due to the pressure from the rapid movement of heavy objects such as vehicles on the top of existing water grates during use, they are prone to popping up under heavy pressure, resulting in positional displacement and exposure of the opening, which could lead to them falling off. In this solution, the outer frame 3 of the water grate is installed in the center of the mounting groove, and the positioning frame 2 is installed on the outside of the outer frame 3. The positioning frame 2 reinforces the connection between the water grate and the sewer opening 1 and limits the water grate from popping up under pressure.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 as well as Figure 3 As shown, the four sides of the outer frame 3 of the drain grate near the center of the drain outlet 1 have limit grooves. A limit rod 7 is fixed at the center of each limit groove. A high-pressure spring 8 is sleeved on the outside of the limit rod 7. A lower rebound pad 9 is fixed to the top of the high-pressure spring 8. An upper rebound pad 10 is installed on the top of the lower rebound pad 9. A limit block 11 is installed on the top of the upper rebound pad 10. The limit rod 7 passes through the interiors of the lower rebound pad 9, the upper rebound pad 10, and the limit block 11. The side of the limit block 11 near the center of the drain outlet 1 is fixedly connected to the outer surface of the drain grate plate 6. The hardness of the upper rebound pad 10 is less than that of the lower rebound pad 9, and the high-pressure spring 8 is a coarse spring with higher pressure resistance.

[0028] In this embodiment, when the water grate plate 6 is subjected to pressure 2, pressure is first applied to the upper rebound pad 10, and then applied to the lower rebound pad 9 through the upper rebound pad 10, and finally to the high-pressure spring 8. This progressive pressure method can effectively reduce the impact force during rebound, thereby reducing the rebound amplitude and avoiding the problem of dislocation due to excessive rebound amplitude.

[0029] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5As shown, positioning claws 12 are evenly distributed on the side of the positioning frame 5 away from the center of the sewer opening 1. Spherical buckles 13 are fixed at both ends of the positioning frame 5 near the center of the sewer opening 1. A pusher frame 14 is rotatably connected to the spherical buckles 13 near the center of the sewer opening 1. A connecting buckle 15 is rotatably connected to the top of the pusher frame 14. An adjusting frame 16 is fixed to the top of the connecting buckle 15. An adjusting screw 17 is threadedly connected to the center of the adjusting frame 16. An adjusting buckle 18 is fixed to the top of the adjusting screw 17. An installation groove is opened inside the center of the top of the drain grate 6. A sealing cap 19 is rotatably connected to the top of the installation groove. An insert 20 is fixed to the lower part of the top of the adjusting screw 17. The adjusting screw 17 passes through the interior of the center of the drain grate 6.

[0030] In this embodiment, after the outer frame 3 and the drain plate 6 of the grate are placed inside the through groove, the adjusting screw 17 is rotated by the adjusting buckle 18. Since the top of the adjusting screw 17 is fixed with an embedded piece 20 on the outside, and the top of the adjusting screw 17 is embedded and connected to the drain plate 6 through the embedded piece 20, the adjusting frame 16 can be moved on the outer surface of the adjusting screw 17 by rotating the adjusting screw 17 while the position of the adjusting screw 17 remains unchanged. This causes the position of the adjusting frame 16 to drop, thereby pushing the pusher 14 to expand and causing the bottom of the positioning frame 5 to move away from the center of the sewer opening 1, so that the positioning claw 12 can penetrate deep into the inner wall of the through groove.

[0031] In summary, the outer frame 3 of the grate is installed at the center of the mounting groove, and the positioning frame 2 is installed on the outside of the outer frame 3. The positioning frame 2 reinforces the connection between the grate and the drain opening 1 and limits the grate's rebound under pressure. When the grate plate 6 is under pressure, pressure is first applied to the upper rebound pad 10, then to the lower rebound pad 9, and finally to the high-pressure spring 8. This progressive pressure effectively reduces the impact force during rebound, thereby reducing the rebound amplitude and preventing dislocation due to excessive rebound. The outer frame 3 and the grate plate 6 are then placed at the drain opening. After entering the groove, the adjusting screw 17 is rotated by the adjusting buckle 18. Since the top of the adjusting screw 17 is fixed with an embedded piece 20 on the outside, and the top of the adjusting screw 17 is embedded and connected to the drain plate 6 through the embedded piece 20, the adjusting frame 16 can be moved on the outer surface of the adjusting screw 17 by rotating the adjusting screw 17 while the position of the adjusting screw 17 remains unchanged. This causes the position of the adjusting frame 16 to drop, thereby pushing the pusher frame 14 to expand and causing the bottom of the positioning frame 5 to move away from the center of the drain opening 1, so that the positioning claw 12 can penetrate deep into the inner wall of the inlet groove.
