Description

TECHNICAL FIELD

[0001] The present application relates to the field of trench drainage devices, in particular to a grate assembly and a water intercepting trench structure. BACKGROUND

[0002] The water intercepting trench refers to a drainage ditch in the cross section of a highway, which mainly plays a role in intercepting precipitation and draining the road surface. The top of the water intercepting trench is provided with a grate. The grate is arranged at the open end of the water intercepting trench to prevent vehicles and pedestrians from falling into the water intercepting trench. The grate has a grid structure. The grate with the grid structure has a plurality of drainage holes. The accumulated water on the road surface falls into the water intercepting trench through the drainage holes. The top of the current grate is convex and has an arched structure. The height from the two sides of the width direction of the grate to the middle of the grate gradually increases. The accumulated water on one side of the width direction of the grate cannot pass the middle of the grate to reach the other side of the width direction of the grate, thereby enhancing the water intercepting effect.

[0003] In actual use, in order to avoid the height difference between the highest point of the grate and the ground from hindering the vehicle passing, a pedal that can swing up and down is installed on both sides of the width direction of the grate, and a spring is installed at the bottom of the grate. Before the vehicle passes through the water intercepting trench, the spring lifts the grate so that the grate is exposed above the ground. The pedal is free to fall on the bottom surface on the side away from the grate. At this time, the grate is in an efficient water intercepting state. When the vehicle passes through the water intercepting trench, the wheels roll on the pedal and then on the grate. The wheels pass through the grate to generate a downward pressure on the spring. The spring is compressed and shrunk, so that the grate is lowered. The height difference between the highest point of the grate and the bottom surface is reduced, thereby improving the smoothness of the vehicle passing through the water intercepting trench. After the vehicle passes through the water intercepting trench, the spring rebounds without the downward pressure of the wheels, pushes the grate up, and makes the grate return to the efficient water intercepting state. However, when the spring rebounds to push the grate, the instantaneous force of the spring is too large, so that the grate is thrown up and completely separated from the water intercepting trench, and then falls back into the water intercepting trench. During the period when the grate is completely separated from the water intercepting trench, pedestrians are easily tripped or hit by vehicles. In addition, the service life of the spring is gradually shortened after being subjected to multiple extreme pressures, thereby causing a potential safety hazard of road traffic. SUMMARY

[0004] The purpose of the present application is to provide a grate assembly and a water intercepting trench structure, which can prevent the grate from being thrown up when the grate is pushed by the spring rebounding, avoid the grate from being completely separated from the water intercepting trench, prevent pedestrians from being tripped or hit by vehicles, eliminate the potential safety hazard of road traffic, and prolong the service life of the spring.

[0005] In order to achieve the above-mentioned purpose, the present application provides a grate assembly of a water intercepting trench structure, which comprises a grate, pedals hinged to both sides of the width direction of the grate, two groups of spring assemblies arranged at the bottom of the grate, the spring assemblies corresponding to the pedals on both sides one by one, and each group of spring assemblies comprising a plurality of springs arranged in a row along the length direction of the grate,

[0006] Each of the foot plates is provided with a limiting block on the lower side of the corresponding spring assembly, and a limiting cavity is formed in the limiting block and opens to one side of the spring assembly.

[0007] In the grate assembly of the water interception trench structure, the limiting plate comprises a limiting plate body fixedly connected to the top of the spring assembly, and a pair of support plates fixedly connected to the top of the limiting plate body, the top of the support plates is fixedly connected to the bottom of the grate, and the pair of support plates are arranged at intervals along the width direction of the grate.

[0008] In the grate assembly of the water interception trench structure, a drainage hole is formed in the limiting plate body and located between the pair of support plates.

[0009] In the grate assembly of the water interception trench structure, the top and bottom of the limiting cavity are fixedly connected with a buffer layer.

[0010] In the grate assembly of the water interception trench structure, the limiting block comprises a sealing plate arranged directly below the foot plate and a base, the base comprises a bottom plate and a side plate vertically connected to the top surface of the bottom plate, the top of the side plate is detachably connected to the bottom of the sealing plate, and the top surface of the bottom plate, the inner side surface of the side plate and the bottom surface of the sealing plate jointly form the limiting cavity.

[0011] In the grate assembly of the water interception trench structure, the spring assembly further comprises an electromagnet corresponding to the spring, and the electromagnet is fixedly connected to the bottom end of the spring.

[0012] The water interception trench structure comprises a trench and the grate assembly according to any one of the above, and further comprises a sunken step formed at the edge of the trench in the width direction, the limiting block on each side corresponds to the sunken step, the limiting block is fixed to the inner side of the sunken step, and the bottom of the spring assembly is fixedly connected to the bottom of the sunken step.

[0013] In the water interception trench structure, the bottom of the sunken step is provided with a positioning hole corresponding to the spring, and the lower end of the spring is arranged in the positioning hole.

[0014] Compared with the prior art, the grate assembly and the water interception trench structure have the following beneficial effects:

[0015] In this embodiment, limiting blocks are provided on both sides of the grate in the width direction. Each limiting block is fixedly connected to both sides of the drainage ditch in the width direction. A limiting plate is fixedly connected to the bottom of the grate. The limiting plate is horizontally arranged and its bottom is fixedly connected to the top of the spring assembly. A limiting cavity is opened on the side of the limiting block near the grate, and the limiting plate extends into the limiting cavity. When the vehicle passes through the drainage ditch, the wheel rolls from the pedal onto the grate, and the wheel presses down on the grate. The grate, through the limiting plate, presses down on the spring in the spring assembly, compressing the spring. The grate and the limiting plate descend synchronously until the limiting plate is inside the limiting cavity. The grate stops descending when its portion abuts against the bottom of the limiting cavity. The limiting plate is partially lifted by the bottom of the limiting cavity, and the bottom of the limiting cavity bears part of the spring's force, reducing the load on the spring, preventing the spring from reaching its limit, and extending the spring's service life. After the vehicle passes through the drainage ditch, the spring rebounds and pushes the grate and the limiting plate to rise synchronously until the portion of the limiting plate inside the limiting cavity abuts against the top of the limiting cavity, at which point the grate stops rising. The top of the limiting cavity then limits the grate, preventing it from being thrown up and completely detached from the drainage ditch, thus preventing pedestrians from tripping or being knocked away from the drainage ditch by vehicles and eliminating road safety hazards.

[0024] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] like Figures 1-5 As shown, a preferred embodiment of the present invention provides a grate assembly for a drainage ditch structure, including a grate 2 and pedals 3 hinged to both sides of the grate 2 in the width direction. The bottom of the grate 2 is provided with two sets of spring assemblies 4, each spring assembly 4 corresponding to one of the pedals 3 on both sides, and respectively located below the corresponding pedal 3. Each set of spring assemblies 4 includes several springs 41 arranged in a row along the length direction of the grate 2.

[0026] Each of the pedals 3 is provided with a limiting block 5 below it. The limiting block 5 is located on the outside of the corresponding spring assembly 4. The limiting block 5 has a limiting cavity 53 that opens to one side of the spring assembly 4. The spring 41 of each set of spring assemblies 4 is fixedly connected to the bottom of the grate 2 through the same limiting plate 7. The limiting plate 7 is arranged horizontally and extends partially into the limiting cavity 53. The bottom of the limiting cavity 53 is higher than the bottom of the spring 41.

[0027] In this embodiment, the width direction of the comb 2 refers to the direction in which the car is traveling.

[0028] In this embodiment, limiting blocks 5 are provided on both sides of the grate 2 in the width direction. The limiting blocks 5 are fixedly connected to both sides of the drainage ditch in the width direction. A limiting plate 7 is fixedly connected to the bottom of the grate 2. The limiting plate 7 is arranged horizontally and its bottom is fixedly connected to the top of the spring assembly 4. A limiting cavity 53 is opened on the side of the limiting block 5 near the grate 2. The limiting plate 7 extends into the limiting cavity 53. When the vehicle passes through the drainage ditch, the wheel rolls from the pedal 3 onto the grate 2. The wheel presses down on the grate 2. The grate 2 presses down on the spring 41 in the spring assembly 4 through the limiting plate 7, compressing the spring 41. The grate 2 and the limiting plate 7 descend synchronously until the limiting plate 7 is in the limiting cavity 53. The grate 2 stops descending when its portion abuts against the bottom of the limiting cavity 53. The limiting plate 7 is partially lifted by the bottom of the limiting cavity 53. The bottom of the limiting cavity 53 bears part of the force of the spring 41, reducing the load intensity of the spring 41, avoiding the spring 41 from being under extreme pressure, and extending the service life of the spring 41. After the vehicle passes through the drainage ditch, the spring 41 rebounds and pushes the grate 2 and the limiting plate 7 to rise synchronously until the portion of the limiting plate 7 inside the limiting cavity 53 abuts against the top of the limiting cavity 53. The grate 2 stops rising, and the top of the limiting cavity 53 acts as a limit for the grate 2, preventing the grate 2 from being thrown up and completely leaving the drainage ditch, preventing pedestrians from being tripped or knocked away from the drainage ditch by vehicles, and eliminating road traffic safety.

[0029] Combination Figure 1 , Figure 2 andFigure 3 As shown in the drawings, the limiting plate 7 comprises a limiting plate body 72 fixedly connected to the top of the spring assembly 4, and a pair of support plates 71 fixedly connected to the top of the limiting plate body 72, the top of the support plate 71 being fixedly connected to the bottom of the grate 2, and the pair of support plates 71 being spaced apart along the width direction of the grate 2.

[0030] The limiting plate body 72 is fixedly connected to the bottom of the grate 2 through the pair of support plates 71, the limiting plate 7 has two connection points with the grate 2, the connection is more firm, the support plate 71 serves as a rib plate of the limiting plate body 72, and the overall strength of the limiting plate 7 is strengthened.

[0031] Preferably, a drainage hole 721 is formed in the limiting plate body 72 and located between the pair of support plates 71.

[0032] Most of the accumulated water on the road falls into the water collecting ditch through the grate 2, and a small part of the accumulated water drops on the limiting plate 7. In order to avoid the accumulated water from being accumulated between the support plates 71 on the two sides of the limiting plate 7, the drainage hole 721 is formed in the limiting plate body 72 and located between the support plates 71 on the two sides, so that the accumulated water can quickly drip downward.

[0033] As shown in the drawings, Figure 4 Further, the top and the bottom of the limiting cavity 53 are fixedly connected with the buffer layer 6.

[0034] The buffer layer 6 is specifically a rubber layer. After the buffer layer 6 is arranged in the limiting cavity 53, when the limiting plate 7 rises or falls, the part of the limiting plate 7 extending into the limiting cavity 53 abuts against the corresponding buffer layer 6. The buffer layer 6 buffers the limiting plate 7 by deforming itself, so that the part of the limiting plate 7 extending into the limiting cavity 53 does not rigidly collide with the top or the bottom of the limiting cavity 53, noise is reduced, and the service life of the extending limiting plate 7 and the limiting block 5 is prolonged.

[0035] The limiting block 5 comprises a sealing plate 51 arranged directly below the pedal 3 and a base 52, the base 52 comprises a bottom plate 522 and a side plate 521 vertically connected to the top of the bottom plate 522, the top of the side plate 521 is detachably connected to the bottom of the sealing plate 51, and the top surface of the bottom plate 522, the inner side surface of the side plate 521 and the bottom surface of the sealing plate 51 together enclose the limiting cavity 53.

[0036] The sealing plate 51 and the base 52 together form the limiting block 5, making it easier for the portion of the limiting plate 7 extending into the limiting cavity 53 to be installed within the limiting cavity 53. When installing the limiting block 5, first use expansion bolts to fix the bases 52 of the two limiting blocks 5 to both sides of the width direction of the drainage ditch. Then, lower the grate 2 so that the portions of the limiting plates 7 extending into the limiting cavity 53 on both sides of the bottom of the grate 2 are directly above the bottom plate 522 of their corresponding bases 52. Finally, install the sealing plate 51 on top of the side plate 521 of the base 52, allowing the limiting plate 7 to extend into the limiting cavity 53. The portion of the sealing plate 51 is pressed down by the bottom of the sealing plate 51. The bottom surface of the sealing plate 51, the inner side surface of the side plate 521 (the side surface of the side plate 521 adjacent to the grate 2), and the top surface of the bottom plate 522 together form the limiting cavity 53. The bottom surface of the sealing plate 51 and the top surface of the bottom plate 522 respectively form the top and bottom of the limiting cavity 53. When the limiting plate 7 is raised and lowered, the portion of the limiting plate 7 extending into the limiting cavity 53 is raised and lowered between the bottom surface of the sealing plate 51 and the top surface of the bottom plate 522. The bottom surface of the sealing plate 51 and the top surface of the bottom plate 522 play a limiting role on the portion of the limiting plate 7 extending into the limiting cavity 53.

[0037] In some embodiments, the base plate 522 and the side plate 521 are integrally formed.

[0038] In this embodiment, the bottom of the grate 2 is fixedly connected to the top of multiple springs 41, and the multiple springs 41 share the pressure, reducing the pressure load on a single spring 41, extending the service life of the springs 41, and avoiding frequent replacements.

[0039] Furthermore, the spring assembly 4 also includes an electromagnet 42 corresponding to each spring 41, with the top end of the electromagnet 42 fixedly connected to the bottom end of the spring 41.

[0040] The top of the electromagnet 42 is fixedly connected to the bottom of the spring 41. When the spring 41 rebounds and pushes the grate 2, the electromagnet 42 is energized and generates magnetic force. The limiting plate 7 is made of metal. The spring 41 and the limiting plate 7 are pulled by the downward magnetic force, which slows down the rise of the limiting plate 7. The limiting plate 7 pulls the grate 2 to prevent the grate 2 from bouncing up quickly.

[0041] like Figure 2 As shown, in this embodiment, the grate 2 is a grid plate. As a standard component on the market, the grid plate has the advantages of being easy to purchase and replace, and having low maintenance costs.

[0042] like Figures 1-5 As shown, a drainage ditch structure includes a ditch 1 and a grate assembly as described above, and also includes recessed steps 11 opened at the edges on both sides of the width direction of the ditch 1. The limiting blocks 5 on both sides correspond one-to-one with the two recessed steps 11. The limiting blocks 5 are fixed to the side of the recessed steps 11, and the bottom of the spring assembly 4 is fixedly connected to the bottom of the recessed steps 11.

[0043] Further, the bottom of the limiting block 5 abuts against the bottom of the sunken step 11, and the side of the limiting block 5 away from the grate 2 is fixedly connected with the side of the sunken step 11.

[0044] Further, the bottom of the sunken step 11 is provided with a positioning hole 12 corresponding to each spring 41, and the lower end of the spring 41 is arranged in the positioning hole 12.

[0045] The positioning hole 12 is provided with a plurality of positioning holes corresponding to the plurality of springs 41 in the spring assembly 4, the electromagnet 42 fixedly connected with the bottom end of the spring 41 is arranged at the bottom of the positioning hole 12, the bottom end of the spring 41 is arranged in the positioning hole 12, and the positioning hole 12 limits the bottom end of the electromagnet 42 and the spring 41 in the horizontal direction.

[0046] The working process of the present application is as follows: the limiting block 5 is arranged on both sides of the width direction of the grate 2, the limiting block 5 is fixedly connected on both sides of the width direction of the water interception ditch, the bottom of the grate 2 is fixedly connected with the limiting plate 7, the limiting plate 7 is horizontally arranged, the bottom of the limiting plate 7 is fixedly connected with the top of the spring assembly 4, the side of the limiting block 5 close to the grate 2 is provided with a limiting cavity 53, the limiting plate 7 extends into the limiting cavity 53, when the vehicle passes through the water interception ditch, the wheel rolls on the tread plate 3 and then on the grate 2, the wheel presses down the grate 2, the grate 2 presses down the spring 41 in the spring assembly 4 through the limiting plate 7, the spring 41 is compressed, the grate 2 and the limiting plate 7 synchronously descend until the part of the limiting plate 7 in the limiting cavity 53 abuts against the bottom of the limiting cavity 53, the grate 2 stops descending, the part of the limiting plate 7 is lifted by the bottom of the limiting cavity 53, the part of the limiting cavity 53 bottom bears the part of the spring 41, the load strength borne by the spring 41 is reduced, the limit pressure borne by the spring 41 is avoided, the service life of the spring 41 is prolonged, after the vehicle passes through the water interception ditch, the spring 41 rebounds to synchronously lift the grate 2 and the limiting plate 7 until the part of the limiting plate 7 in the limiting cavity 53 abuts against the top of the limiting cavity 53, the grate 2 stops ascending, the top of the limiting cavity 53 limits the grate 2, the grate 2 is prevented from completely separating from the water interception ditch after being thrown, the pedestrian is prevented from being tripped or the vehicle from being hit away from the water interception ditch, and the road traffic safety is eliminated.

[0047] In summary, the embodiment of the present application provides a grate assembly and a water interception ditch structure, which prevents the grate 2 from being thrown when the grate 2 is pushed by the spring 41, avoids the grate 2 from completely separating from the water interception ditch, prevents the pedestrian from being tripped or the vehicle from being hit away from the water interception ditch, eliminates the road traffic safety hazard, and prolongs the service life of the spring 41.

[0048] The above merely describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, several improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
