Description

Technical Field

[0001] The utility model relates to the technical field of road administration drainage, in particular to a permeable drainage ditch for municipal roads. Background Art

[0002] Permeable drainage ditch plays a key role in urban planning and construction. Its structure mainly includes permeable bricks, drainage boards and bottom plates. The porous properties of permeable bricks enable them to quickly penetrate rainwater into the ground. The drainage system composed of drainage boards and bottom plates effectively guides rainwater to water collection facilities to prevent water accumulation and flooding. The role of this drainage ditch is to reduce flood risks, improve urban water environment, increase greening levels and reduce road pollution. For example, a permeable drainage ditch for municipal roads disclosed in the authorization announcement number CN212223504U includes a ditch body, the ditch body is detachably connected to a rainwater grate, the ditch body is movably connected to a permeable device, the permeable device includes a permeable plate and a fixed frame, the permeable plate and the fixed frame are slidably connected, the fixed frame and the ditch body are cooperatively arranged, the permeable plate includes a permeable concrete layer, a pressure mesh layer and a permeable pressure plate, and the ends of the permeable pressure plates close to each other are fixedly connected to the pressure mesh layer. The pressure mesh layer and the permeable concrete layer are fixedly connected, and a movably connected permeable device is provided on the drainage ditch to effectively prevent debris from entering the ditch during drainage, thereby ensuring that the ditch will not be blocked. However, the permeable plate in this technical solution slides with the fixed frame, which results in a large sliding amount between the permeable plate and the fixed frame. After long-term use, the permeable plate is damaged due to sliding wear, and when maintaining the permeable plate at a later stage, the staff is required to separate the permeable device and the ditch body through a pull ring. The operation process is time-consuming and labor-intensive, especially when frequent drainage ditch maintenance is required, which will increase the labor intensity of the staff and affect the maintenance efficiency.

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.

[0018] See also Figure 1-5 The utility model provides an embodiment: a permeable drainage ditch for municipal roads, comprising a drainage ditch monomer 1 and a permeable grate 3 installed at the top opening position of the drainage ditch monomer 1, two symmetrical positioning holes are installed on both inner walls of the drainage ditch monomer 1, an inverted trapezoidal drainage cavity 2 is arranged inside the drainage ditch monomer 1, two symmetrical pins 10 are installed on both outer walls of the permeable grate 3, elastic limiting structures 9 interconnected with one end of the pins 10 are installed on both inner walls of the permeable grate 3, and the pins 10 on the outer walls of both sides of the permeable grate 3 are automatically pushed into the positioning holes on the inner wall of the drainage ditch monomer 1 under the action of the elastic limiting structures 9, thereby realizing stable and rapid connection between the permeable grate 3 and the drainage ditch monomer 1;

[0019] A gear bidirectional pushing structure is installed between the two elastic limiting structures 9 in the same X-axis direction, and a dial button 4 for driving the elastic limiting structure 9 to move is installed at the corner position of the top of the water-permeable grate 3;

[0020] When the user needs to remove the permeable grate 3 from the top of the drainage ditch monomer 1, the user can push the two dial buttons 4 on the same side of the Y axis, and the dial buttons 4 drive the elastic limiting structure 9 to act, that is, at this time, the rack monomer 8 drives another rack monomer 8 to slide synchronously through the gear monomer 701 and the central axis 7, and at this time, the two pins 10 in the same X-axis direction move toward the direction of the vertical center line of the drainage ditch monomer 1 until the end of the pin 10 withdraws from the outside of the positioning hole, so that the permeable grate 3 and the drainage ditch monomer 1 are unlocked;

[0021] The elastic limiting structure 9 includes a hollow shaft seat 901 fixed inside the water-permeable grate 3, and a valve stem 902 slidably installed inside the hollow shaft seat 901, one end of the valve stem 902 is fixedly connected to one end of the pin shaft 10, and the other end of the valve stem 902 passes through the outside of the hollow shaft seat 901 and is installed with a connecting piece 904, the top of the connecting piece 904 is fixedly connected to the bottom end of the dial button 4, and a spring 903 is installed at one end of the hollow shaft seat 901 close to the connecting piece 904, and the spring 903 is sleeved on the outer circumference of the valve stem 902, the gear bidirectional pushing structure is a central axis 7 rotatably installed inside the water-permeable grate 3, and a gear monomer 701 fixed at one end of the central axis 7, a rack monomer 8 is fixed on the outside of the connecting piece 904 close to the gear monomer 701, and the rack monomer 8 and the central axis 7 are meshed with each other;

[0022] The dial button 4 drives the connecting piece 904, the valve stem 902 and the pin shaft 10 to slide in the direction of the central axis 7. Since the connecting piece 904 and the rack monomer 8 are fixedly connected, the connecting piece 904 and the rack monomer 8 drive another rack monomer 8 to move synchronously through the central axis 7 and the gear monomer 701, so that the two pin shafts 10 can be synchronously withdrawn from the outside of the positioning hole. In case of emergency or emergency maintenance, the water-permeable grate 3 can be quickly replaced or maintained;

[0023] A U-shaped rib 5 is fixed on the outer wall of one side of the drainage ditch monomer 1, and a U-shaped inner groove 6 plugged with the U-shaped rib 5 is arranged on the outer wall of the other side of the drainage ditch monomer 1. The U-shaped rib 5 is made of a hard plastic component, and the length of the U-shaped rib 5 is equal to the depth of the U-shaped inner groove 6. The staff takes out multiple sets of assembled drainage ditch monomers 1 and permeable grates 3, and the head and tail ends of two adjacent drainage ditch monomers 1 are plugged through the U-shaped rib 5 and the U-shaped inner groove 6, so as to realize the extended layout function of the drainage ditch, and its construction layout efficiency is high, which provides convenience for the staff to build the ditch;

[0024] The bottom of the drainage ditch monomer 1 is provided with a plurality of equally spaced sinking grooves 101;

[0025] Rainwater enters the inverted trapezoidal drainage cavity 2 through the permeable grate 3. When the rainwater moves along the extension direction of the side ditch, the impurities carried in the rainwater will settle into the sinking trough 101, that is, the impurities are intercepted by the sinking trough 101. When the staff removes the permeable grate 3, the staff can salvage the impurities in the sinking trough 101.

[0026] When the embodiment of the present application is in use, the staff first takes out the drainage ditch monomer 1 and the permeable grate 3 to be assembled, and then buckles the permeable grate 3 at the opening position at the top of the drainage ditch monomer 1. Then, the pins 10 on the outer walls of both sides of the permeable grate 3 are automatically pushed into the positioning holes on the inner wall of the drainage ditch monomer 1 under the action of the elastic limiting structure 9, so as to achieve a stable and fast connection between the permeable grate 3 and the drainage ditch monomer 1. The elastic limiting structure 9 can provide a certain connection strength to ensure that the connection between the permeable grate 3 and the drainage ditch monomer 1 is firm and reliable, which helps to prevent connection failure due to external force or other factors, and ensure the normal operation of the drainage system. When the user needs to remove the permeable grate When removing the drain gutter 3 from the top of the drainage gutter monomer 1, the user can push the two dial buttons 4 on the same side Y axis, and the dial buttons 4 drive the elastic limiting structure 9 to move, that is, at this time, the rack monomer 8 drives the other rack monomer 8 to slide synchronously through the gear monomer 701 and the central axis 7. At this time, the two pins 10 in the same X-axis direction move toward the vertical center line of the drainage gutter monomer 1 until the end of the pin 10 withdraws from the outside of the positioning hole, so that the permeable grate 3 and the drainage gutter monomer 1 are unlocked. In this process, the staff does not need to operate laboriously or use large tools, and the replacement or maintenance of the permeable grate 3 becomes more economical and efficient. For the large-scale operation and maintenance of the urban drainage system, the overall maintenance cost can be reduced.
