Description

Technical Field

[0002] Transportation is one of the important areas of carbon emissions, accounting for about 10% of my country's total carbon emissions. According to statistics, my country has built more than 3,300 pairs of expressway service areas. Based on the annual average carbon dioxide emissions of about 1,000 tons per pair of service areas, the annual average carbon dioxide emissions of expressway service areas across the country are about 3.3 million tons. As an important ancillary facility on the expressway, the realization of low-carbon development of expressway service areas is of great significance to the low-carbon process of the entire transportation system.

[0003] The current exhaust gas degradation equipment uses a fan to introduce the exhaust gas into the equipment so that the exhaust gas contacts the photocatalytic composite material and is treated. After the equipment is started, the fan is in a continuous working state. When the traffic volume is small, the degradation equipment will be in an idling state for a long time, resulting in a large energy consumption. Therefore, we proposed a highway exhaust gas degradation equipment to solve the above problems. Summary of the invention

[0042] The power storage mechanism includes a plurality of lifting pedals 6, a fixed rack 61, a second gear 62 and a third gear 63. A plurality of second grooves are provided on the mounting plate 1. The plurality of lifting pedals 6 are movably mounted in the second grooves. The fixed rack 61 is fixedly mounted at the lower end of the lifting pedal 6. The lower end of the fixed rack 61 extends into the mounting groove. A fixing frame 13 is fixedly mounted in the mounting groove. The second gear 62 and the third gear 63 are rotatably mounted on the fixing frame 13. When the fixed rack 61 moves downward, the fixed rack 61 meshes with the second gear 62. When the compression spring 52 recovers its deformation, the movable rack 51 quickly returns to its initial position. When the third gear 63 is in the state, the third gear 63 will be driven to move. At this time, the second gear 62 rotates with the third gear 63, but because the fixed rack 61 is not engaged with the second gear 62 at this time, the third gear 63 is in a rotatable state and does not affect the movement of the movable rack 51. A one-way transmission component is provided between the second gear 62 and the third gear 63, and the third gear 63 is engaged with the movable rack 51. A rebound part is provided at the lower end of the lifting pedal 6, and the lifting pedal 6 and the movable plate 54 are provided with anti-slip convex patterns.

[0044] The rebound member includes a fixed tube 64, a return spring 641 and an insertion rod 642. A slot connected to the second groove is provided on the mounting plate 1. The fixed tube 64 is fixedly installed in the slot. The return spring 641 is fixedly installed between the fixed tube 64 and the lifting pedal 6. The insertion rod 642 is fixedly installed at the lower end of the lifting pedal 6. The insertion rod 642 is inserted in the fixed tube 64.

[0045] The method of use of the present invention is as follows:

[0046] When the car is driving on the mounting plate 1 and passes the lifting pedal 6, the lifting pedal 6 will move up and down. When the lifting pedal 6 is lowered, the fixed rack 61 contacts the second gear 62 and drives the second gear 62 to rotate, and drives the third gear 63 to rotate through the ratchet 622 and the pawl 631. When the lifting pedal 6 is lifted by the elastic force of the return spring 641, the second gear 62 rotates in the opposite direction, the ratchet 622 and the pawl 631 are in an active state, and the third gear 63 is not subjected to force and does not rotate.

[0047] When the lifting pedal 6 is lowered and the second gear 62 drives the third gear 63 to rotate, the third gear 63 drives the movable rack 51 to move in the direction of the compression spring 52 under the limiting action of the limiting rod 5, and the rotating wedge 544 on the trigger plate 543 is sequentially inserted into the tooth groove of the one-way rack 53. When the third gear 63 stops rotating, the rotating wedge 544 can produce a clamping effect on the movable rack 51 through the one-way rack 53, and the compression spring 52 is deformed by the force. When the car passes through multiple lifting pedals 6, the compression spring 52 gradually accumulates force.

[0048] When the car drives above the movable plate 54, the trigger plate 543 will move away from the movable rack 51, and the rotating wedge 544 will disengage from the one-way rack 53. At this time, the movable rack 51 will quickly return to its initial state under the elastic force of the compression spring 52 to drive the first gear 55 to rotate. With the cooperation of the rotating shaft 56, the transfer rod 542 and the rotating rod 31, the guide fan 42 is driven to rotate, and the exhaust gas can be introduced into the billboard 4, so that the exhaust gas contacts the photocatalytic composite material 41 and is oxidized and degraded.

[0049] The above is a detailed introduction to a highway exhaust gas degradation device provided by the present invention. The description of the specific embodiment is only used to help understand the method and core idea of ​​the present invention.
