[0032] The base 101 is formed by pouring concrete into a plurality of support frames 207 and solidifying, and the support frame 207 is fixedly welded between the fixed plate 103.

[0033] The both ends of the fixed plate 103 are provided with round holes 208, the comb-shaped plate 102 is fixedly connected with an L-shaped connecting shaft 209, and one end of the L-shaped connecting shaft 209 extends into the inside of the round hole 208.

[0034] The gasket 104 is made of rubber material, and one end of the gasket 104 is aligned with one end of the fixed plate 103.

[0035] One end of the screw conveyor 204 is fixedly connected with a rotating shaft 210, a first gear 211 is sleeved on the rotating shaft 210, an inclined groove 212 is formed in the rotating shaft 210, an elastic sheet 213 is fixedly connected in the inclined groove 212, a one-way groove 214 is formed in the inside of the first gear 211, a transmission shaft 215 is rotatably connected on the water channel 201, a second gear 216 and a third gear 217 are fixedly connected on the transmission shaft 215, and the second gear 216 is engaged with the first gear 211.

[0037] Installation process

[0038] First, in the construction phase, according to the design requirements in the position of the expansion joint foundation construction, the water channel 201 is installed in the appropriate position under the expansion joint through the fixed hole 203 of the connecting belt 202, ensuring the correct drainage direction of the flow guide groove 205. Install the auger 204 in the water channel 201, fix the rotating shaft 210 and the auger 204, and cover the first gear 211. Install the transmission shaft 215 on the water channel 201, fix the second gear 216 and the third gear 217, make the second gear 216 mesh with the first gear 211, adjust the position of each gear to ensure smooth transmission. Rotate the connecting frame 219 on the transmission shaft 215, and make the toothed plate 218 rotatingly connected below the comb-shaped plate 102 pass through the frame 219 and mesh with the third gear 217.

[0039] Build multiple support frames 207 and pour concrete. After the concrete solidifies, a stable base 101 is formed. The fixed plate 103 is welded on the support frame 207 to ensure firm connection. Circular holes 208 are opened at both ends of the fixed plate 103, and the L-shaped connecting shaft on the comb-shaped plate 102 is inserted into the circular holes 208 to allow the comb-shaped plate 102 to rotate freely relative to the fixed plate 103. The installation cylinder 105 is embedded on the base 101, and the tension spring 106 is installed in the installation cylinder 105, with one end connected to the comb-shaped plate 102 and the other end fixed to the bottom of the installation cylinder 105. Rubber pads 104 are attached to the top of the base 101 and the fixed plate 103 to achieve noise reduction and provide some cushioning capacity.

[0040] Workflow

[0041] In daily use, when the building, bridge or road expands or contracts due to temperature changes, foundation settlement or other factors, the angle between the two bases 101 may change, and the comb-shaped plate 102 will also tilt accordingly. At this time, the tension spring 106 adjusts the tension according to the tilt state of the comb-shaped plate 102 to maintain a certain pre-tightening force.

[0042] When a vehicle drives to the expansion joint, the wheels first contact one end of the comb-shaped plate 102 that is flush with the base 101. As the vehicle moves forward, the wheels press down on the comb-shaped plate 102. Due to the rotating connection of the L-shaped connecting shaft and the elasticity of the tension spring 106, the comb-shaped plate 102 smoothly rotates around the L-shaped connecting shaft, the tension spring 106 is moderately stretched, and the impact force of the wheels is cushioned. The comb-shaped plate 102 is gradually transferred to the other comb-shaped plate 102, and the entire process is smooth and stable.

[0043] When it rains, rainwater flows into the water channel 201. The bottom of the water channel 201 is designed with a certain slope, and the flow guide groove 205 gradually decreases from the water inlet to the water outlet 206 along the slope direction. Under the action of gravity and water flow, the rainwater smoothly flows out of the water outlet 206, avoiding water damage to the building structure.

[0044] When the comb tooth type plate 102 rotates, the lower tooth plate 218 rotates, the tooth plate 218 drives the third gear 217 engaged with it to rotate synchronously, since the third gear 217 and the second gear 216 are fixedly connected on the transmission shaft 215, the second gear 216 is engaged with the first gear 211, the power is transmitted in turn, drives the first gear 211 and the rotating shaft 210 sleeved in it to rotate, finally realizes the rotating of the auger 204. Through the cooperation of the one-way groove 214 in the first gear 211 and the elastic sheet 213 on the rotating shaft 210, the reverse rotation of the first gear 211 is limited, the one-way stable rotation of the auger 204 is ensured, the sundries is effectively broken and pushed, the auger 204 adopts a special spiral blade structure, the blade presents a certain inclination angle, the sundries such as sand and dust entering the water channel is pushed along the guide groove to the water outlet by the thrust of the spiral surface and is discharged, the daily maintenance workload is reduced, and the service life of the expansion joint is prolonged.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
