Description

Technical Field

[0001] This utility model relates to the technical field of drainage facilities for highway engineering, and in particular to a rapid flow channel for highway engineering. Background Technology

[0002] In the field of highway engineering, chutes play a crucial role as a key drainage facility. Their main function is to guide water flows with significant drops in elevation over short distances. They are often connected to roadside ditches or serve directly as outlets for road surface runoff. Simultaneously, they can quickly remove residual water from road cut slopes, playing a vital role in preventing slope collapses, landslides, and debris flows caused by waterlogging, as well as protecting the stability of the highway subgrade.

[0003] Chinese Patent No. CN222183608U discloses a rapid flow channel for highway engineering, including a drainage channel with a rapid flow channel fixedly connected to the drainage channel. A slow flow channel is fixedly connected to the other end of the rapid flow channel. A drainage mechanism is provided between the drainage channel and the rapid flow channel. The drainage mechanism includes a fixed frame fixed between the drainage channel and the rapid flow channel, with a gate plate slidably connected inside the fixed frame. A slow flow mechanism is provided inside the rapid flow channel, including a rotating rod rotating inside the rapid flow channel. A circular array of rotating blades is fixedly connected to the rotating rod. A diversion mechanism is provided between the drainage channel and the rapid flow channel, including a diversion channel connecting the drainage channel and the rapid flow channel.

[0004] The aforementioned existing technologies have several shortcomings: To address the problem of impurities clogging the rapid flow channel, a filter screen is used. However, in practical applications, this method has been found to have significant drawbacks. When the water carries debris such as leaves, the leaves easily clog the filter screen's mesh, drastically reducing the effective area for water flow and severely lowering drainage efficiency. Furthermore, existing rapid flow channels are mostly constructed of cast concrete or masonry. While these traditional structures can meet drainage requirements to some extent, they have numerous drawbacks during construction. Concrete casting requires a series of complex procedures, including formwork construction, concrete mixing and pouring, and vibration, and requires waiting for the concrete to reach its design strength, resulting in a long construction period. Masonry structures, on the other hand, have high requirements for stone selection and masonry techniques, making construction cumbersome and requiring extensive manual labor. Moreover, if these two traditional structures are damaged during later use, their strong integrity makes repair difficult, often requiring demolition and reconstruction of the damaged area and surrounding area, consuming significant manpower, resources, and time, leading to high maintenance costs.

[0031] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0032] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Please see Figure 1-5This utility model provides a rapid flow channel for highway engineering, including a drainage channel 1, a channel body, a rotating shaft 3, a filter plate 4, a housing 5, an anti-clogging mechanism 6, a transmission mechanism 7, and a connecting mechanism 8. The channel body is assembled from multiple prefabricated channel bodies 2, which have a U-shaped structure. The rotating shaft 3 is rotatably mounted between the inner walls of both sides of the drainage channel 1, and multiple blades 31 are arranged around the rotating shaft 3. The filter plate 4 is fixedly mounted between the inner walls of both sides of the drainage channel 1, and the housing 5 is fixedly mounted between the inner walls of both sides of the drainage channel 1 and located above the filter plate 4. Through the above structural design, the channel body is modularly designed and assembled from multiple prefabricated channel bodies 2. When a prefabricated channel body 2 is damaged during later use, due to its modular design, only the damaged prefabricated channel body 2 needs to be replaced individually, without the need for large-scale dismantling and reconstruction of the entire rapid flow channel. This not only reduces the difficulty and complexity of maintenance but also greatly saves the manpower, material resources, and time costs required for maintenance, significantly reducing maintenance costs.

[0035] An anti-clogging mechanism 6 is installed inside the housing 5. The anti-clogging mechanism 6 is used to clean the filter plate 4 to prevent it from clogging. The anti-clogging mechanism 6 includes a reciprocating screw 61, which is rotatably mounted between the inner walls of the two sides of the housing 5. Two guide rods 62 are fixedly mounted between the inner walls of the two sides of the housing 5 and above the reciprocating screw 61. A movable seat 63 adapted to the reciprocating screw 61 is slidably sleeved between the two guide rods 62. An L-shaped cleaning plate 64 is fixedly connected to the upper side wall of the movable seat 63. The L-shaped cleaning plate 64 has several bristles on the side wall near the filter plate 4. The bristles are made of nylon filaments. Nylon bristles have good wear resistance and flexibility. Through the anti-clogging mechanism 6, the L-shaped cleaning plate 64 can continuously clean the filter plate 4, preventing leaves from clogging the filter plate 4 and keeping the mesh of the filter plate 4 unobstructed, thus ensuring stable drainage efficiency.

[0036] The transmission mechanism 7 is installed on one side of the outer wall of the drainage trough 1. The transmission mechanism 7 can drive the anti-blocking mechanism 6 to operate while the rotating shaft 3 rotates. The transmission mechanism 7 includes an idler wheel 71, which is rotatably installed on one side of the outer wall of the drainage trough 1. One end of the rotating shaft 3 extends to the outside of the drainage trough 1 and is fixedly connected to a drive gear 72 that meshes with the idler wheel 71. One end of the reciprocating screw 61 extends to the outside of the drainage trough 1 and is fixedly connected to a driven gear 73 that meshes with the idler wheel 71. The transmission mechanism 7 can use the kinetic energy of the water flow to drive the anti-blocking mechanism 6 to operate without the need for an additional drive source, resulting in lower operating costs and easier maintenance.

[0037] The connecting mechanism 8 is installed on the precast trough body 2. The connecting mechanism 8 is used to complete the connection between the precast trough body 2 and the drainage trough 1, as well as between multiple precast trough bodies 2. The connecting mechanism 8 includes two symmetrically distributed side plates 81 fixedly installed at both ends of the precast trough body 2 and at one end of the drainage trough 1 near the precast trough body 2. At least two connecting holes 82 are opened on the side plates 81. Two adjacent side plates 81 are connected together by bolts 83 and nuts 84 through the connecting holes 82. The above-mentioned connecting mechanism 8 can conveniently complete the splicing of each precast trough body 2 without complicated on-site construction operations, which greatly shortens the construction cycle and improves construction efficiency.

[0038] To further explain, multiple inclined buffer plates 21 are spaced apart on the inner walls of both sides of the precast tank body 2 along the direction of water flow. The buffer plates 21 are provided with several protruding buffer blocks 211. When the water flow impacts the buffer plates 21, the buffer blocks 211 can disperse the impact force of the water flow, slow down the water flow speed, reduce the scouring of the precast tank body 2 by the water flow, and improve the service life.

[0039] To further explain, two symmetrically distributed reinforcing plates 22 are fixed between the buffer plate 21 and the inner wall of the precast trough 2, which can enhance the strength of the buffer plate 21.

[0040] To further explain, one end of the precast trough body 2 and the end of the drainage trough 1 near the precast trough body 2 both have U-shaped docking grooves 23. A sealing gasket is provided inside the U-shaped docking groove 23. The other end of the precast trough body 2 is fixedly connected to a plug block 24 that is compatible with the U-shaped docking groove 23. After the plug block 24 is inserted into the U-shaped docking groove 23, it can enhance the connection effect between two adjacent precast trough bodies 2, as well as the connection effect between the precast trough body 2 and the drainage trough 1, and ensure the sealing performance.

[0041] It is explained here that the reciprocating screw 61 has two threaded grooves with the same pitch and opposite directions on its surface. A slider that matches the threaded groove is provided below the moving seat 63. By rotating the reciprocating screw 61 in one direction, the side of the helical groove pushes the slider placed in the helical groove to drive the moving seat 63 to perform axial reciprocating motion.

[0042] It should be noted that this utility model is a rapid flow channel for highway engineering. During installation, the location of the rapid flow channel is determined at the construction site. First, the drainage channel 1 is fixed in the predetermined position. Then, the plug block 24 on the first prefabricated channel body 2 is inserted into the U-shaped mating groove 23 on the drainage channel 1. At this time, the connecting holes 82 on the two side plates 81 that are in contact with each other will be aligned. Then, the bolt 83 is passed through the connecting hole 82 and the bolt 83 is fixed by using the nut 84, thereby completing the fixing between the side plates 81 that are in contact with each other, and thus connecting the drainage channel 1 with the first prefabricated channel body 2. Then, the remaining prefabricated channel bodies 2 are spliced ​​together in this way. In use, when rainwater flows into the drainage trough 1, the water flow impacts the blades 31, causing the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the drive gear 72 to rotate, which in turn drives the idler gear 71 to rotate. The rotation of the idler gear 71 causes the driven gear 73 to drive the reciprocating screw 61 to rotate, thereby causing the moving seat 63 to move back and forth continuously along the guide rod 62. During the movement of the moving seat 63, the L-shaped cleaning plate 64 cleans the filter plate 4 to prevent leaves and other impurities from clogging the filter plate 4. When the water flows into the precast tank body 2, the water flow impacts the inclined buffer plate 21. The inclination angle of the buffer plate 21 changes the direction of the water flow. At the same time, the buffer block 211 further disperses the impact force of the water flow, thereby slowing down the water flow speed. The spaced arrangement of multiple buffer plates 21 can continuously buffer the water flow, effectively reducing the scouring of the precast tank body 2 by the water flow, thereby improving the service life of the precast tank body 2.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
