DETAILED DESCRIPTION

[0021] 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. 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.

[0022] See also Figure 1-7 The utility model provides an embodiment: an urban road drainage structure for energy-saving municipal engineering, comprising an inverted U-shaped bottom frame 1 and a circular drainage channel 2 whose ends can be connected to each other, which is arranged at the bottom of the inverted U-shaped bottom frame 1. Side blocks 4 are fixed on the outer walls of both sides of the inverted U-shaped bottom frame 1, and upper grilles 7 are arranged on the tops of the two side blocks 4. Connecting plates 401 are fixed on both ends of the side blocks 4, and a plurality of circular holes with equal spacing are arranged on the surface of the connecting plates 401;

[0023] Rectangular convex seats 8 for plugging with the side block seat 4 are installed on both sides of the bottom end of the upper grille 7, two secondary filter frames 5 are installed inside the inverted U-shaped bottom frame 1 below the upper grille 7, and a guide pipe 6 extending to the inside of the loop drain 2 is installed at the bottom end of the secondary filter frame 5. Elastic limiting structures 10 are installed on both sides of the top of the side block seat 4, and a sliding tongue 9 for moving the elastic limiting structure 10 is installed at the top of the side block seat 4. A rectangular lower groove for plugging with the rectangular convex seat 8 is provided at the top of the side block seat 4, and countersunk holes are provided at both ends of the rectangular convex seat 8;

[0024] When the staff needs to install the side block seat 4 and the upper grille 7, the staff needs to operate the sliding tongue 9 in advance, so that the sliding tongue 9 drives the elastic limiting structure 10 to move, so that the pin end of the elastic limiting structure 10 withdraws from the rectangular groove, and the rectangular protrusion 8 is inserted into the rectangular groove at the top of the side block seat 4. After the user releases the sliding tongue 9, the pin end of the elastic limiting structure 10 automatically pushes into the rectangular protrusion 8, thereby locking the side block seat 4 and the rectangular protrusion 8. The stable upper grille 7 can reduce the failure and damage of the drainage system caused by falling off or damage, and extend the service life of the drainage system;

[0025] A middle vertical plate 3 is fixed to the top of the loop drain 2, and the upper surface of the middle vertical plate 3 is in contact with the lower surface of the upper grille 7;

[0026] A cavity 201 is provided inside the meandering drain 2, and a meandering inner tube 202 is fixed at the other end of the meandering drain 2. One end of the meandering inner tube 202 extends to the outside of the meandering drain 2. When multiple drainage structures are connected, the head and tail ends of two meandering drains 2 are connected, that is, the meandering inner tube 202 is inserted into the cavity 201 of another meandering drain 2, thereby forming a long-path pipeline structure.

[0027] A filter plate 501 is fixed at one end of the secondary filter frame 5. Rainwater enters the secondary filter frame 5 through the upper grille 7. At this time, the filter plate 501 performs secondary filtration on the rainwater, which can reduce the failure and failure of the drainage system caused by impurities clogging. The filter plate 501 is made of hard plastic material, and the upper grille 7 is made of stainless steel. Both hard plastic and stainless steel have good durability and corrosion resistance, and can withstand long-term use and various environmental conditions without being easily corroded or damaged, thereby ensuring the long-term stability and service life of the filter plate 501 and the upper grille 7.

[0028] The elastic limiting structure 10 includes a lower groove 1005 arranged at one end of the side stop seat 4, and a baffle 1001 slidably installed on one side of the lower groove 1005. Pins 1002 and recessed columns 1003 are respectively installed on the outer walls of both sides of the baffle 1001. The pin 1002 is concentrically plugged with the countersunk hole. A coil spring 1004 is fixed to one end of the recessed column 1003. One end of the coil spring 1004 is fixedly connected to the inner wall of one side of the lower groove 1005. When the staff manually slides the sliding tongue 9, the sliding tongue 9 drives the baffle 1001 and the recessed column 1003 to slide, so that the coil spring 1004 is in a compressed state, and then the pin 1002 withdraws to the countersunk hole at the end of the rectangular protrusion 8, so that the pin 1002 is no longer connected to the rectangular protrusion 8.

[0029] When the embodiment of the present application is used, the staff first takes out a plurality of the road drainage structures, so that the head and tail ends of the plurality of loop drainage channels 2 are connected in sequence to form a long-sized drainage pipe. The drainage pipe is distributed on both sides and the center of the road in two types: a curb drainage channel and a central drainage channel, so as to realize the function of discharging rainwater and accumulated water. When the rainwater flows to the upper grille 7, the leaves and other materials in the rainwater are initially intercepted by the upper grille 7. The intercepted rainwater enters the secondary filter frame 5 and undergoes a secondary filtration treatment. At this time, the relatively clean rainwater without debris enters the loop drainage channel 2 through the guide pipe 6 and is continuously collected. The drainage structure is filtered by the upper grille 7 and the secondary filter frame 5. It can effectively remove impurities, leaves, mud and other solid particles and pollutants in rainwater, improve the quality and cleanliness of rainwater, and reduce the pollution of surface water and water bodies when the treated rainwater enters the underground pipe network. The bottom end of the upper grille 7 is plugged into the side block seat 4 through the rectangular boss 8, and the pin end of the elastic limiting structure 10 locks the rectangular boss 8, so that the four elastic limiting structures 10 are used to form a connection point for the corners of the upper grille 7, which can ensure that the upper grille 7 is firmly fixed on the side block seat 4 to avoid the grille from falling out due to vibration or external force, such as the grille falling off due to trampling or rolling by people and vehicles, thereby improving the stability and reliability of the drainage system.
