Description

Technical Field

[0001] The utility model relates to the technical field of road traffic engineering, in particular to a drainage ditch device. Background Art

[0002] In the field of road traffic engineering, the effectiveness and safety of drainage systems are crucial for ensuring unobstructed traffic, preventing waterlogging, and reducing traffic accidents. Especially in complex and changing road conditions, such as mountain curves, urban expressways, and racetracks, drainage ditches, as key drainage facilities, have a direct impact on the overall performance and service life of the road due to their design and installation quality.

[0003] Traditionally, drainage ditch covers are often connected to the ditch body by snap-fitting, or by bolting through the cover plate and directly screwing it into the ditch body. Although this design meets basic installation requirements to a certain extent, it is inadequate when faced with extreme operating environments. Specifically, for roads that have extremely high requirements for the cover plate's anti-fall-off performance, such as areas frequently impacted by high-speed vehicles, severe road vibrations, and extreme weather (such as strong winds), traditional fixing methods often cannot guarantee the long-term stability of the cover plate, especially cast iron covers, which have quality issues, while the long-term stability of the bolted connection to the concrete ditch body is difficult. This is especially true on racetracks, where the extremely high speeds of the cars create significant aerodynamic effects and ground friction. These external forces can easily cause the cover plate to loosen or even fall off, which not only affects the normal driving of the cars, but can also pose a safety threat to vehicles and personnel on the track, and even cause serious accidents.

Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in this utility model without affecting the efficacy and purpose of the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of this utility model. Changes or adjustments in their relative relationships should also be considered as the scope of the implementation of this utility model without substantially changing the technical content.

[0067] See also Figures 1 to 13The utility model provides a drainage ditch device, including a drainage ditch body 1 and a cover plate 2. The drainage ditch body 1 is provided with a groove 11, and also includes a guard 3 and a connecting mechanism. The drainage ditch body 1 is fixedly connected to the guard 3 on both sides of the groove 11. The inner side of the guard 3 is fixedly provided with a limit block A31 and a limit block B32. There are also a plurality of threaded holes 33 on the guard 3. The cover plate 2 is provided with a limit card groove A21 and a limit card groove B22 on the first side along the width direction, and a limit card groove C23 and a limit card groove D24 on the second side. The limit card groove A21 is fixed with a limit card groove B22 on the first side along the width direction. The side is open and the lower side has a groove bottom plate A211, the lower side of the limit slot B22 is open and the upper side has a groove bottom plate B221, and the lower sides of the limit slot C23 and the limit slot D24 are both open; the connecting mechanism connects the cover plate 2 to the edge guard 3, and the limit block A31 and the limit block B32 of the edge guard 3 on one side respectively extend into the limit slot A21 and the limit slot B22 on the first side of the cover plate 2, and the limit block A31 and the limit block B32 of the edge guard 3 on the other side respectively extend into the limit slot C23 and the limit slot D24 on the second side of the cover plate 2.

[0068] During assembly of the gutter device of the present invention, the edge guard 3 can be fixedly connected and assembled during the manufacture of the gutter body 1, and then the cover plate 2 is installed. The side of the cover plate 2 provided with the limiting slots A21 and B22 is designated as the left side, and the side provided with the limiting slots C23 and D24 is designated as the right side. The cover plate 2 is tilted so that the right side is higher than the left side. The left side of the cover plate 2 is positioned close to the left edge guard 3, and the limiting blocks A31 and B32 on the left edge guard 3 are respectively inserted into the limiting slots A21 and B22. The right side of the cover plate 2 is then laid downwardly and leveled, so that the limiting slots C23 and D24 on the right side of the cover plate 2 are respectively installed onto the limiting blocks A31 and B32 on the right side guard 3. After the cover plate 2 is placed, at least the right side of the cover plate 2 is connected to the edge guard 3 by a connecting mechanism to stabilize the upper and lower positions of the cover plate 2. The connection mechanism stably connects the cover plate 2 and the edge guard 3, which can form the first anti-loosening effect of the cover plate 2. At the same time, the edge guard 3 and the cover plate 2, through the cooperation of the limit block A31, the limit block B32, the limit slot A21 and the limit slot B22, etc., can limit the upper and lower positions of the cover plate 2, thereby achieving the second anti-loosening effect. Specifically, when the cover plate 2 is installed, see Figure 3 and Figure 4 The limit block A31 is clearance-matched with the bottom plate A211 on the lower side of the limit slot A21. If the cover plate 2 swings upward, the bottom plate A211 will resist the limit block A31, thereby limiting the cover plate 2 from swinging upward. The limit block B32 is clearance-matched with the bottom plate B221 on the upper side of the limit slot B22. If the cover plate 2 swings downward, the bottom plate B221 of the limit slot B22 will resist the limit block B32, thereby limiting the cover plate 2 from swinging downward.

[0069] See also Figures 1 to 13The present invention is further described below with reference to several specific embodiments:

[0070] Example 1:

[0071] See also Figures 1 to 8 , is a schematic diagram of the structure of embodiment 1. In this embodiment, see Figure 1 and Figure 5 As a preferred design, the connection mechanism includes several connecting bolts 4 and several threaded holes 33 on the edge guard 3. The connecting bolts 4 pass through the cover plate 2 and are screwed into the threaded holes 33, thereby fixing the cover plate 2 to the edge guard 3. In addition, the left and right sides of the cover plate 2 are respectively fixed to the edge guards 3 via the connecting bolts 4. The edge guard 3 can be made of cast iron or other suitable similar materials, which has a good screw connection effect with the connecting bolts 4. Compared with the existing method of directly screwing the connecting bolts 4 into the drainage ditch body 1, it can better maintain long-term stability.

[0072] In this embodiment, see Figure 5 and Figure 6 As a preferred design, the number of limit blocks A31 and limit blocks B32 on the edge guard 3 is N, where N ≥ 2. The specific number can be determined according to the length of a single edge guard 3 and the cover plate 2. The limit blocks A31 and limit blocks B32 are matched one by one, and a limit block A31 and a limit block B32 are arranged in pairs to form a limit block group. Correspondingly, the limit slots A21, limit slots B22, limit slots C23, and limit slots D24 on the side of the cover plate 2 are also N. In this embodiment, the number of threaded holes 33 on the edge guard 3 is also N. The limit blocks A31 and limit blocks B32 in each limit block group are respectively arranged on both sides of the threaded hole 33 along the length direction of the edge guard 3 (i.e., the front and back sides), so as to better achieve the loosening effect of the cover plate 2.

[0073] In this embodiment, see Figure 7 and Figure 8 As a preferred design, the upper side of the limit slot D24 has a bottom plate D241, which has the same structure as the opposite limit slot B22 and also serves to limit the downward movement of the cover plate 2. Because the limit block A31 cooperates with the limit slot A21 to prevent the cover plate 2 from moving downward, the upper side of the limit slot C23 is set to be open, which allows the limit block A31 to be as close as possible to the top surface of the cover plate 2 and the edge guard 3, thereby better ensuring that the bottom plate A211 below the limit slot A21 can have a greater thickness.

[0074] In this embodiment, see Figure 5 and Figure 6As a preferred design, a bearing surface 34 and a limiting side surface 35 are provided in the edge guard 3. The bearing surface 34 is preferably a flat surface, and the limiting side surface 35 is preferably a flat surface perpendicular to the bearing surface 34. An L-shaped mounting groove for accommodating the left and right sides of the cover plate 2 is formed between the two. The cover plate 2 is pressed on the bearing surface 34, and the limiting side surface 35 is gap-matched with the left and right side surfaces of the cover plate 2, so that the left and right positions of the cover plate 2 can be positioned and limited. The limiting block A31 and the limiting block B32 are arranged on the limiting side surface 35, and the threaded hole 33 is arranged on the bearing surface 34.

[0075] In this embodiment, see Figure 5 and Figure 6 As a preferred design, the side of the edge guard 3 is provided with a slag discharge hole 36 connected to the bottom of the threaded hole 33. During on-site installation, if any debris enters the threaded hole 33, it can be quickly discharged through the slag discharge hole 36, thereby avoiding the connection bolt 4 from being unable to be screwed into the threaded hole 33 due to the debris. It is convenient and flexible to use.

[0076] In this embodiment, see Figure 5 and Figure 6 As a preferred design, the drainage ditch body 1 is made of concrete, and the bottom of the edge guard 3 has a connecting plate 37 embedded in the drainage ditch body 1, and preferably, a connecting through-hole 371 is also provided on the connecting plate 37. When pouring the concrete drainage ditch body 1, the connecting plate 37 at the bottom of the edge guard 3 is pre-buried in the drainage ditch body 1, and the concrete enters the connecting through-hole 371, thereby firmly connecting the edge guard 3 to the drainage ditch body 1 to form a whole. The edge guard 3 is preferably made of cast iron, which has good structural strength, can be firmly connected to the drainage ditch body 1, and can be stably screwed with the connecting bolts 4, and is not prone to wear during long-term use. In other embodiments, the edge guard 3 can also be made of other metal materials and non-metallic materials with sufficient structural strength and hardness, such as stainless steel.

[0077] In this embodiment, see Figure 5 and Figure 6 As a preferred design, a socket 38 is provided on the outer surface of the edge guard 3, extending along the width direction of the drainage ditch body 1 and penetrating to the inner side (the side facing the center of the groove 11). The socket 38 can be used to install other types of covers, especially covers made of lightweight materials. When laying drainage ditch devices on both sides of the road, multiple drainage ditch devices are combined and arranged in sequence along the length of the road. Cast iron covers 2 can be selected in most places, but other types of covers may be required in some places. In this case, the other types of covers 2 can be placed on the drainage ditch body 1, and then bolts can be inserted into the socket 38 from the outer side of the edge guard 3 and screwed into the side of the other types of covers 2, which is convenient for installation.

[0078] Example 2:

[0079] See also Figures 9 to 13 , is a structural diagram of the second embodiment, wherein the drainage ditch body 1 is omitted. In this embodiment, a different connection mechanism is used, see Figure 10 and Figure 12 The connecting mechanism includes several snap-in components 5 installed on the cover plate 2, and a snap-in component 5 is provided at least on the second side of the cover plate 2. A snap-in block is provided on the edge guard 3. Preferably, the limit block B32 on the edge guard 3 is used as the snap-in block, or the limit block A31 can be used as the snap-in block, or an independent snap-in block can be provided additionally. The clamping assembly 5 includes a clamping member 51 and an elastic structure. The clamping member 51 includes an upper clamping plate 511, a lower clamping plate 512, and an intermediate connecting block 513 fixedly connecting the upper clamping plate 511 and the lower clamping plate 512. The clamping member 51 can move relative to the cover plate 2 in the width direction of the cover plate 2 and is restricted by the cover plate 2 in the height direction. That is, the clamping member 51 can be completely fixed to the cover plate 2 in the height direction, or it can have a slight displacement space relative to the cover plate 2 (in some cases there may be slight shaking), so that the clamping member 51 cannot move up and down relative to the cover plate 2; the elastic structure connects the clamping member 51 and the cover plate 2 and provides elastic force to the clamping member 51. The elastic force of the elastic structure can drive the clamping member 51 to move toward the side of the cover plate 2, and make the upper clamping plate 511 and the lower clamping plate 512 respectively located on the upper and lower sides of the clamping block of the edge guard 3.

[0080] When assembling the connecting mechanism in this embodiment, refer to Figure 9 、 Figure 12 and Figure 13 After the edge guard 3 is fixedly connected and assembled with the drainage ditch body 1, the cover plate 2 is installed. The side of the cover plate 2 with the limiting card slot A21 and the limiting card slot B22 is recorded as the left side, and the side with the limiting card slot C23 and the limiting card slot D24 is recorded as the right side. First, install the clamping component 5 on the cover plate 2. The clamping component 5 is installed on the cover plate 2 near the right side. In the natural state, the elastic force of the elastic structure can make the clamping part 51 extend to the right into the limiting card slot D24. The cover plate 2 is tilted with the right side higher than the left side, and the left side of the cover plate 2 is moved close to the left edge guard 3, and the limit block A31 and the limit block B32 on the left edge guard 3 are respectively inserted into the limit slot A21 and the limit slot B22, and then the right side of the cover plate 2 is laid down flat. During the laying process, the clamping part 51 of the clamping assembly 5 can be moved to the middle of the cover plate 2 by a tool such as a wrench to make it leave the limit slot D24. At this time, the elastic structure is in an elastic energy storage state; then the cover plate 2 is laid flat, and the limit slot C23 and the limit slot D24 on the right side are respectively installed on the limit block A31 and the limit block B32 of the right edge guard 3. After the cover 2 is placed, the clamping member 51 is released. Under the elastic force of the elastic structure, the clamping member 51 is pushed to the right and enters the limit slot D24. The upper clamping plate 511 and the lower clamping plate 512 respectively enter the upper and lower sides of the clamping block (i.e., the limit block B32) on the right side guard 3. Figure 13 In the state shown, a clamping effect is achieved, ensuring that the right side of the cover plate 2 cannot move up and down, and a stable connection between the cover plate 2 and the edge guard 3 is achieved. In addition, a clamping component 5 can also be provided on the first side (i.e., the left side) of the cover plate 2 to stably connect the left side of the cover plate 2 to the left edge guard 3, and its working principle is the same.

[0081] In this embodiment, see Figure 10 and Figure 13 As a preferred design, the upper and lower side surfaces of the clamping block are both inclined surfaces. The clamping block gradually becomes thicker from the inside to the outside, the upper side surface gradually decreases from the outside to the inside, and the lower side surface gradually increases from the outside to the inside. When the clamping part 51 of the clamping assembly 5 moves toward the clamping block, it can be better clamped on the clamping block through the guidance of the upper and lower side surfaces of the clamping block, and the clamping part 51 will not swing up and down relative to the clamping block.

[0082] In this embodiment, see Figure 11 and Figure 13 As a preferred design, the cover plate 2 is provided with a snap-fit mounting block 26. The upper snap-fit plate 511 and the lower snap-fit plate 512 of the snap-fit member 51 are located on the upper and lower sides of the snap-fit mounting block 26, respectively, and are clearance-fitted therewith. This allows the snap-fit mounting block 26 to restrict the vertical position of the snap-fit member 51, preventing it from moving up and down relative to the cover plate 2. At the same time, the snap-fit member 51 can move left and right along the width of the cover plate along the snap-fit mounting block 26. The snap-fit member 51 is easy to install on the cover plate 2; it simply needs to be inserted into the snap-fit mounting block 26 from the side of the cover plate 2. Further preferably, the elastic structure of the clamping assembly 5 includes a clamping spring 52, one end of which is fixed to the middle connecting block 513 of the clamping member 51, and the other end is provided with two elastic sheets 521. The elastic sheets 521 are used to connect with the clamping mounting block 26 and can be compressed and deformed to provide elastic force. The clamping mounting block 26 is provided with a V-shaped slot 261, and the elastic sheet 521 is provided with a V-shaped snap-in portion 522 that is mounted in the V-shaped slot 261. When the clamping member 51 is moved toward the middle of the cover plate 2, the elastic sheet 521 is squeezed and deformed, entering an elastic energy storage state, and can apply an elastic force to the clamping member 51 toward the side of the cover plate 2. The elastic structure can also adopt a structure such as a compression spring.

[0083] The other parts of the drainage ditch device in this embodiment are the same as those in the above-mentioned embodiment 1 and will not be described in detail.

[0084] The connection mechanism in the present invention is not limited to the forms in the above two embodiments, and an existing suitable structure can also be used as long as the cover plate 2 and the edge guard 3 are stably connected.

[0085] As can be seen from the above, the drainage ditch device of the present invention has the following beneficial effects:

[0086] 1. The cover plate 2 is fixedly connected to the drainage ditch body 1 by setting the edge guard 3. The edge guard 3 is stably connected to the drainage ditch body 1. The edge guard 3 can be made of cast iron or similar materials. The connecting mechanism connects the cover plate 2 to the edge guard 3. The connection is stable and reliable, can maintain long-term stability, and has a good anti-loosening effect. At the same time, a limit block A31 and a limit block B32 are also provided on the edge guard 3, which cooperate with the limit card groove A21 and the limit card groove B22 on the side of the cover plate 2 to limit the up and down shaking of the cover plate 2, forming a second anti-loosening effect, forming a double insurance for preventing the cover plate 2 from falling off, and can provide better anti-loosening of the cover plate 2 in limited road space with greater impact, thereby reducing safety risks.

[0087] 2. The connecting mechanism can use connecting bolts 4 to fix the cover plate 2 on the edge guard 3. The screw connection between the edge guard 3 and the connecting bolts 4 is stable and reliable, long-term stable, and has a good anti-loosening effect; the connecting mechanism can use a clamping assembly 5 to stably connect the cover plate 2 to the edge guard 3, which is easy to install and has a stable connection.

[0088] 3. In terms of installation, the edge guard 3 can be assembled with the drainage ditch body 1 when the drainage ditch body 1 is manufactured. The installation of the cover plate 2 on the edge guard 3 is also convenient and quick, which can shorten the construction period and facilitate the subsequent operation and maintenance replacement, saving a lot of construction cost and time cost.

[0089] In summary, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0090] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
