Description

Technical Field

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

[0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It refers to the materials and equipment used, and the technical activities such as survey, design, construction, maintenance, and repair carried out. It also refers to the objects of engineering construction, that is, various engineering facilities built on the ground, underground, or on land, which directly or indirectly serve human life, production, military, and scientific research, including roads, pipelines, water supply and drainage, etc.

[0003] When the existing road drainage device is draining water, garbage on the road, such as leaves, garbage bags, etc., will also flow into the waterway along with the water. These garbage will continue to flow with the water in the waterway and eventually accumulate together, causing blockage, making the drainage ineffective and causing waterlogging on the road. In some waterways, flat filters are installed to filter out debris in the water to prevent garbage from accumulating. Although this method can prevent the waterway from being completely blocked, the location of the garbage will still cause the filter to be blocked. The fine mesh on the filter will also reduce the speed at which the water falls, which is not conducive to the rapid discharge of the water. In addition, this design method requires the installation of a continuous and uninterrupted filter to achieve the corresponding effect. It is time-consuming and labor-intensive to lay and clean, and the materials required for manufacturing are also greatly increased. Utility Model Content

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] See attached Figure 1 -Attached Figure 3 The utility model embodiment discloses a civil engineering road drainage device, including a waterway 1, a plurality of water guide components 2, and a plurality of cleaning mechanisms 3. The waterway 1 is basically U-shaped and used for guiding and draining. The plurality of water guide components 2 are laid on the waterway 1, and a first through hole 4 can be enclosed between two adjacent water guide components 2. Each water guide component 2 is provided with a plurality of second through holes 5 connecting the inside and outside of the waterway 1, so that water and debris can enter the waterway 1 through the first through hole 4 and the second through hole 5; the plurality of cleaning mechanisms 3 are located in the waterway 1 and arranged along the direction of the waterway 1, and each cleaning mechanism 3 is rotatably connected between two opposite side walls in the waterway 1. The rotation axis formed when the cleaning mechanism 3 rotates is horizontally arranged and perpendicular to the direction of the water in the waterway 1. The rotation axis is located at the center of gravity of the cleaning mechanism 3, so that the cleaning mechanism 3 can rotate under the impact of the water falling outside the waterway 1 and the driving effect of the water flowing inside the waterway 1.

[0043] In actual use, the water outside the waterway 1 will fall into the waterway 1 through the second through hole 5 on the water guide component 2 and the first through hole 4 enclosed by two adjacent water guide components 2. The impact force generated when the water falls and the force generated when the water in the waterway 1 flows will drive the cleaning mechanism 3 to rotate, so that the cleaning mechanism 3 can continuously filter the water. Since the cleaning mechanism 3 is rotatably connected in the waterway 1, the cleaning mechanism 3 can be set intermittently, and no matter how much debris is carried on it, it will not affect the speed of the water falling into the waterway. When there are too many debris on a cleaning mechanism 3, the cleaning mechanism 3 will no longer filter the debris in the water during the rotation process, but let the debris flow with the water and be cleaned by the subsequent cleaning mechanism 3, so it will not affect the discharge of the water in the waterway. In general, by using the civil engineering road drainage device, the debris in the water can be filtered, and the speed of the water falling into the waterway and the discharge of the water in the waterway will not be affected, and the cleaning mechanism can be set intermittently.

[0044] Furthermore, since the presence of water on the surface of an object will reduce friction, making it easy for pedestrians to slip or vehicles to skid, an anti-skid layer can be provided on the water-guiding component 2 to increase friction and prevent pedestrians from slipping or vehicles from skidding. The anti-skid layer can be made of polyurethane coating, which has excellent wear resistance, oil resistance, chemical resistance, adjustability, performance diversity, strong adhesion, high and low temperature resistance, and is non-toxic and harmless, and is an environmentally friendly coating.

[0045] See attached Figure 1 , Attachment Figure 3 and attached Figure 4 Due to the problem of the structure of the waterway 1 itself, the middle part of the water guide component 2 is suspended in the air. When pedestrians or vehicles pass by, the part where the water guide component 2 contacts the waterway 1 is subjected to the greatest force, and is very easy to be damaged under continuous impact and vibration. In order to solve the above problem, the following design is made in this embodiment. Specifically, a plurality of vertically arranged guide holes 6 with top openings are provided on the edges of the tops on both sides of the waterway 1. The plurality of guide holes 6 are linearly arranged along the extension direction of the waterway 1. The water guide component 2 includes a plate body 21 and two elastic members 22. The plate body 21 is laid on the waterway 1 to block the waterway 1 and provide protection. Both ends of the plate body 21 along the direction of the waterway 1 are provided with a substantially U-shaped notch 211, so that the first through hole 4 can be enclosed between two adjacent plate bodies 21, and a plurality of second through holes 5 are all provided on the plate body 21; the elastic member 22 is substantially L-shaped, and the two elastic members 22 are relatively arranged at the bottom of the plate body 21 and are respectively stuck on the edges of the tops on both sides of the waterway 1 for buffering and shock absorption.

[0046] By setting the elastic member 22, a buffering and shock absorbing effect can be achieved, which greatly reduces the damage to the plate body 21 caused by impact and vibration, thereby extending its service life; there are various materials or structures with buffering effects. In this embodiment, buffering and shock absorption are achieved through the material of the elastic member 22. Specifically, the material of the elastic member 22 is EVA, which is soft and elastic, has good impact strength, is non-toxic and odorless, has good toughness, is resistant to low temperatures, acid and alkali, ozone, mildew, and organic solvents, and has excellent electrical insulation.

[0047] See attached Figure 3 and attached Figure 4 In order to enrich the functions of the water guide component 2, the following design is also carried out in this embodiment. Specifically, a plurality of second through holes 5 are linearly arranged along a direction perpendicular to the extension of the water channel 1, each second through hole 5 is in a long strip shape and is arranged along the extension direction of the water channel 1, a first protrusion 8 is provided on the plate body 21 between two adjacent second through holes 5, and second protrusions 9 are provided on both sides of the side wall of the water channel 1 of the plate body 21. There is a spacing between the corresponding first protrusions 8 on different plate bodies 21, and the corresponding second protrusions 9 on different plate bodies 21 abut against each other, which can guide the water on the plate body 21 to move the water to the first through hole 4 and the second through hole 5, and can also serve as a blind path.

[0048] Through the design of the above-mentioned structure, the water on the water guiding component 2 can be prevented from spreading around, and the water on the water guiding component 2 can be guided. Some water that does not have time to fall can be diverted through the channel between the first protrusion 8 and the second protrusion 9 and the channel between two adjacent first protrusions, so that the water on the water guiding component 2 can fall into the waterway 1 as quickly and completely as possible; in addition, the setting of the first protrusion 8 and the second protrusion 9 can also serve as a blind path and increase the friction of the water guiding component 2, which can guide the blind and prevent pedestrians from slipping on the water guiding component 2 as much as possible.

[0049] Since the elastic member 22 is elastic, it is easy to deform when pedestrians and vehicles pass by, which may cause the water guide component 2 to be skewed and its position to change easily after being reset. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, a plurality of vertically arranged guide members 7 are provided at the bottom of the plate body 21, each guide member 7 corresponds to a guide hole 6 and is slidably connected to the guide hole 6, and the length of the guide member 7 in the vertical direction is greater than the thickness of the elastic member 22 in the vertical direction, so that the guide member 7 can contact the waterway 1 before the elastic member 22, thereby guiding the movement of the plate body 21 and the elastic member 22, and the depth of the guide hole 6 in the vertical direction is greater than the length of the guide member 7 in the vertical direction, so that the elastic member 22 can play a buffering role.

[0050] The above-mentioned structural design can prevent the water guide component 2 from moving and dislocating in the horizontal direction after installation. When the elastic member 22 is cushioned and shock-absorbing by its own material, that is, when the elastic member 22 is made of elastic material, such as rubber, the setting of the guide member 7 can also prevent the elastic member 22 from deforming after long-term use, causing the plate body 21 to tilt.

[0051] See attached Figure 2 , Attachment Figure 5 and attached Figure 7 In order to enable the cleaning mechanism 3 to filter and purify the water in the waterway 1 by rotation, the following design is carried out in this embodiment. Specifically, the cleaning mechanism 3 includes a connecting component 31 and two rotating parts 32. The connecting component 31 is detachably rotatably connected to the waterway 1; the two rotating parts 32 are relatively arranged on the connecting component 31, and each rotating part 32 is provided with a plurality of hooks 321 for hooking debris in the water.

[0052] Through the design of the above structure, not only can the hook 321 be rotated to continuously hook debris in the water body, such as leaves, garbage bags, etc., but the cleaning mechanism 3 can also be removed from the waterway 1 by disassembling the connecting component 31, so as to facilitate maintenance and cleaning of the cleaning mechanism 3.

[0053] Furthermore, the hook 321 can be made of a flexible material to prevent pricking the hands during the cleaning process, while also reducing the weight so that the cleaning mechanism 3 can be rotated more easily; a hollow rigid material can also be used to reduce the weight.

[0054] See attached Figure 2 and attached Figure 8 When the connecting component 31 rotates, a certain friction force will be generated between it and the waterway 1. The greater the friction force, the more difficult it is for the connecting component 31 to rotate. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, multiple groups of bearings 10 are provided in the waterway 1. The multiple groups of bearings 10 are linearly arranged along the direction of the waterway 1. Each group of bearings 10 is composed of two bearings 10 relatively arranged on the inner walls on both sides of the waterway 1. The connecting component 31 is rotatably connected to the waterway 1 through the bearings 10 to reduce the friction force when the connecting component 31 rotates.

[0055] Through the design of the above structure, the friction force generated when the cleaning mechanism 3 rotates can be reduced as much as possible, making its rotation smoother and able to rotate with less force, that is, it can still function normally when there is less water entering the waterway 1, and the debris in the water can be salvaged and cleaned by rotation.

[0056] See attached Figure 2 and attached Figure 5 -Attached Figure 8In order to make the connection component 31 detachably rotatably connected in the waterway 1, the following design is carried out in this embodiment. Specifically, the connection component 31 includes two frames 311, two moving parts 312, two baffles 313, two springs 314, and two positioning parts 315. The two frames 311 are arranged opposite to each other and connected by a connecting plate 16. The frames 311 are arranged in a rectangular ring shape. The opposite sides of the two frames 311 are provided with third through holes 11, and the separated sides of the two frames 311 are provided with fourth through holes 12; the two moving parts 312 are respectively slidably connected in the two third through holes 11; the two baffles 313 are respectively slidably connected in the two frames 311 and fixedly connected to the corresponding moving parts 312; the two springs 314 are respectively located in the two frames 311 and sleeved Installed on the outside of the corresponding moving part 312, one end of the spring 314 abuts against the side of the frame 311 close to the connecting plate, and the other end abuts against the baffle 313 and presses the baffle 313 against the side of the frame 311 away from the connecting plate; the two positioning members 315 are respectively slidably connected in the two fourth through holes 12, and the positioning member 315 can move along the fourth through holes 12 and extend out of the frame 311 or retract into the frame 311, so that the positioning member 315 can be inserted into the bearing 10 or withdrawn from the bearing 10. A positioning groove 13 is provided on the positioning member 315, and a positioning block 14 corresponding to the positioning groove 13 is provided at the hole in the middle of the bearing 10. After the positioning member 315 is inserted into the bearing 10, the positioning block 14 can be inserted into the positioning groove 13 to prevent the connection parts of the positioning member 315 and the bearing 10 from rotating relative to each other.

[0057] Through the design of the above structure, force is applied to make the two moving parts 312 approach each other, and the two positioning parts 315 will be retracted into the two frames 311 respectively. At this time, the cleaning mechanism 3 can be placed between the two bearings 10 or taken out of the waterway 1, and then the two moving parts 312 are released. Under the elastic action of the spring 314, the baffle 313 will move and reset along the direction of the frame 311 and the moving part 312, so that the two positioning parts 315 are respectively extended from the two frames 311. If the cleaning mechanism 3 is located between the two bearings 10 at this time, the two positioning parts 315 can be respectively inserted into the holes in the middle of the two bearings 10 to connect the cleaning mechanism 3 to the waterway 1.

[0058] See attached Figure 5 and attached Figure 6After long-term use, the waterway 1 will inevitably produce various dirt, which will reduce the size of the internal space of the waterway 1. If the cleaning mechanism 3 is slidably connected to the inner wall of the waterway 1, as the dirt in the waterway 1 becomes thicker and thicker, the cleaning mechanism 3 will become more and more difficult to rotate until it stops rotating, making it unable to play the role of filtering the water body. If the size of the cleaning mechanism 3 is much smaller than the size of the inside of the waterway 1, the entire water body cannot be cleaned. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, bristles 15 are provided on the side of each rotating member so that the rotating member can clean the bottom of the plate body 21, the two side walls and the bottom of the waterway 1 during rotation.

[0059] Through the design of the above structure, the bristles 15 of the cleaning mechanism 3 can continuously clean the inner wall of the waterway 1 and the bottom of the plate 21 during the rotation. In addition, compared with the sliding connection between rigid structures, the sliding connection between the rigid structure and the flexible structure has smaller friction, and the friction between the rigid structure and the flexible structure remains basically unchanged after the rigid structure is deformed.
