Description

Technical Field

[0001] The utility model relates to the field of road drainage, and more specifically, it relates to a municipal road drainage structure. Background Technique

[0002] Municipal road drainage refers to the measures taken to drain the accumulated water on the road surface. Usually, the road surface water converges to the gutter according to the slope of the road surface, and then flows into the drain pipe through the rainwater inlet of the gutter, and then is discharged to the nearby sewage pool or water bodies such as rivers, lakes, and seas through the outlet of the drain pipe.

[0003] The existing road drainage structure is a square drainage cover cast in the cement road surface, and the drainage groove on the surface of the drainage cover is used for drainage. Since there are often pedestrians walking on the drainage cover on the road surface, the drainage cover cast in the cement can provide strong support, but there are also certain disadvantages. In order to ensure the drainage volume, the width of the drainage groove is very wide. When the width of the drainage groove is too large, when items such as mobile phones and keys of people accidentally fall, they are likely to directly fall into the sewer, making it inconvenient for people to fish out the fallen items from the bottom of the sewer.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a municipal road drainage structure.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a municipal road drainage structure, including a drainage frame and a drainage cover. The drainage cover is slidably connected to the inner wall of the top of the drainage frame in the vertical direction. A protection plate is arranged at the bottom of the drainage cover. The side wall of the protection plate abuts against the inner wall of the drainage frame. A buffer pad is fixedly connected to the top of the protection plate. Through holes for water passage are opened on both the buffer pad and the protection plate. A number of connecting rods are jointly arranged between the drainage cover and the protection plate. A positioning member for making the drainage cover relatively fixed to the drainage frame is arranged on the side wall of the drainage cover.

[0007] The utility model is further arranged as: the positioning member is a positioning bump slidably connected to the side wall of the drainage cover. A spring is jointly fixedly connected between the positioning bump and the drainage cover. A positioning hole for the positioning bump to be embedded is opened on the inner wall of the top of the drainage frame.

[0008] The utility model is further arranged as: a number of threaded pipes are welded to the bottom of the drainage cover. One end of the connecting rod is threadedly connected to the threaded pipe. Connecting holes for the connecting rod to pass through are opened on both the protection plate and the buffer pad. A limiting ring is threadedly connected to the outer wall of the bottom of the connecting rod, and the limiting ring abuts against the bottom surface of the protection plate.

[0009] The present utility model is further configured such that: a plurality of dovetail blocks are fixedly connected to the side wall of the drainage cover, and dovetail grooves for the dovetail blocks to slide into are formed in the top inner wall of the drainage frame in the vertical direction.

[0010] The present utility model is further configured such that: the cross section of the protection plate is arc-shaped, and the horizontal height on both sides of the protection plate is greater than the horizontal height in the middle of the protection plate.

[0011] The present utility model is further configured such that: four support rods which are used for supporting the bottom of the protection plate and are inclined are fixedly connected to the bottom inner wall of the drainage frame.

[0012] The present utility model is further configured such that: the buffer pad is made of rubber material.

[0013] To sum up, the present utility model has the following beneficial effects: when the drainage cover drains water, the drainage cover is located on the top inner wall of the drainage frame and is relatively fixed to the latter through the positioning member. When an item accidentally falls from the drainage groove on the drainage cover, the item passes through the drainage groove and gradually falls downward in the drainage frame until the item abuts against the buffer pad, causing the buffer pad to deform. The buffer pad plays a buffering role for the item, reducing the damage to the item when it falls on the protection plate. At this time, the item falls on the protection plate. The user pulls the drainage cover upward to gradually separate it from the top inner wall of the drainage frame. When pulling the drainage cover upward, the connecting rod, the buffer pad, the protection plate and the dropped item are driven to move upward until the connecting rod, the buffer pad, the protection plate and the dropped item are separated from the inside of the drainage frame, thus facilitating the taking of the dropped item on the surface of the protection plate and preventing the item from falling into the sewer and causing blockage, thereby improving the drainage efficiency of the drainage structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment:

[0021] A municipal road drainage structure, as Figures 1 to 4As shown in the figure, it includes a drainage frame 1 and a drainage cover 2. A number of drainage grooves for draining water are provided on the drainage cover 2. The drainage cover 2 is slidably connected to the top inner wall of the drainage frame 1 in the vertical direction. A protective plate 3 is provided at the bottom of the drainage cover 2. The cross-section of the protective plate 3 is arc-shaped, and the horizontal height on both sides of the protective plate 3 is greater than the horizontal height in the middle of the protective plate 3, so that when the water flow is on the protective plate 3, it will flow through the protective plate 3 to the bottom of the drainage frame 1 faster. The side wall of the protective plate 3 abuts against the inner wall of the drainage frame 1, and a buffer pad 4 is adhesively bonded to the top of the protective plate 3 with waterproof glue. The buffer pad 4 is made of rubber material. Through holes 13 for water passage are provided on both the buffer pad 4 and the protective plate 3. The through holes 13 on the buffer pad 4 and the through holes 13 on the protective plate 3 are arranged in one-to-one correspondence. The rubber material has a good buffering effect. A number of connecting rods 5 are jointly provided between the drainage cover 2 and the protective plate 3. External threads are provided at both ends of the connecting rod 5. A positioning member for making it relatively fixed to the drainage frame 1 is provided on the side wall of the drainage cover 2. The positioning member is a positioning bump 6 slidably connected to the side wall of the drainage cover 2. A spring is jointly installed between the positioning bump 6 and the drainage cover 2. A positioning hole 7 for the positioning bump 6 to be embedded is provided on the top inner wall of the drainage frame 1. When the drainage cover 2 is located on the top inner wall of the drainage frame 1 to drain accumulated water, at this time, the positioning bump 6 is embedded in the positioning hole 7, and the accumulated water can flow into the drainage frame 1 through the drainage grooves on the drainage cover 2. At this time, when the accumulated water flows downward, it will contact the buffer pad 4 and the protective plate 3, and drain the accumulated water through the through holes 13 on the buffer pad 4 and the through holes 13 on the protective plate 3. Then the accumulated water flows to the bottom of the drainage frame 1. When an item accidentally falls from the inside of the drainage groove on the drainage cover 2, at this time, the item passes through the drainage groove and gradually falls downward in the drainage frame 1 until the item abuts against the buffer pad 4, causing the buffer pad 4 to deform. The buffer pad 4 plays a buffering role for the item, reducing the damage to the item when the item falls on the protective plate 3. At this time, the item falls on the protective plate 3. The user pulls up the drainage cover 2 to gradually separate it from the top inner wall of the drainage frame 1. When pulling up the drainage cover 2, it drives the dovetail block 10, the positioning bump 6, the spring, the connecting rod 5, the buffer pad 4, the protective plate 3 and the dropped item to move upward. At this time, the positioning bump 6 gradually disengages from the positioning hole 7, and the spring undergoes elastic deformation so that the positioning bump 6 can disengage from the positioning hole 7 until the connecting rod 5, the buffer pad 4, the protective plate 3 and the dropped item disengage from the inside of the drainage frame 1 and are gradually exposed outside, thus facilitating the taking of the dropped item on the surface of the protective plate 3. And the connection strength between the drainage cover 2 and the drainage frame 1 is improved by the connection between the dovetail block 10 and the dovetail groove 11, avoiding the blockage caused by the item falling into the sewer, thereby improving the drainage efficiency of the drainage structure.

[0022] As Figures 1 to 4As shown, the side wall of the drain cover 2 is pre-embedded with four dovetail blocks 10, and the top inner wall of the drain frame 1 is provided with a dovetail groove 11 in the vertical direction for the dovetail block 10 to slide into. When the drain cover 2 is located on the top inner wall of the drain frame 1 to drain the accumulated water, the positioning protrusion 6 is embedded in the positioning hole 7, and the dovetail block 10 is embedded in the dovetail groove 11. The bottom surface of the dovetail block 10 and the bottom inner wall of the dovetail groove 11 fit each other so that the drain cover 2 is stably placed on the top inner wall of the drain frame 1.

[0023] like Figures 1 to 4 As shown, four threaded tubes 8 are welded to the bottom of the drain cover 2, and one end of the connecting rod 5 is threadedly connected to the threaded tube 8. The protective plate 3 and the buffer pad 4 are both provided with connecting holes 14 for the connecting rod 5 to pass through. The connecting holes 14 on the protective plate 3 and the connecting holes 14 on the buffer pad 4 are arranged one by one. The bottom outer wall of the connecting rod 5 is threadedly connected to a limiting ring 9, and the limiting ring 9 is in conflict with the bottom surface of the protective plate 3. When one of the drain cover 2, the connecting rod 5 and the protective plate 3 is damaged and needs to be replaced, first screw the limiting ring 9 to disengage it from the bottom outer wall of the connecting rod 5, and then pull the protective plate 3 and the buffer pad 4 downward. At this time, the connecting holes 14 on the protective plate 3 and the threaded holes on the buffer pad 4 gradually stop contacting the outer peripheral wall of the connecting rod 5, and then screw the connecting rod 5 again to disengage the top outer wall of the connecting rod 5 from the threaded tube 8, so that one of the protective plate 3, the connecting rod 5 and the drain cover 2 can be partially replaced, so that there is no need to replace the entirety.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the bottom inner wall of the drainage frame 1 is pre-embedded with four support rods 12 which are inclined and used to support the bottom of the protective plate 3. When the drainage cover 2 is located on the top inner wall of the drainage frame 1, and the dovetail block 10 is embedded in the dovetail groove 11, and the positioning protrusion 6 is embedded in the positioning hole 7, the four support rods 12 and the bottom of the protective plate 3 are in contact with each other to support the protective plate 3, so that when the accumulated water flows to the bottom of the drainage frame 1 through the drainage groove on the drainage cover 2, the accumulated water will impact the protective plate 3. At this time, the support rods 12 support the protective plate 3, thereby improving the stability of the protective plate 3 when the accumulated water impacts the protective plate 3.

[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
