Referring to fig. 4 and 6, the fixed frame 5 is provided with the abutting assembly 6, and the abutting assembly 6 comprises a sliding rack 61 and an abutting plate 62. The fixing frame 5 is provided with a sliding groove 55, the sliding groove 55 is vertically arranged, the sliding groove 55 and the guide groove 53 are located on the side wall of the fixing frame 5, the sliding rack 61 is arranged in the sliding groove 55 in a penetrating mode, and the sliding rack 61 is meshed with the driving gear 23. The sliding rack 61 is thus located on the side of the drive gear 23 remote from the drive rack 25, and the abutment plate 62 is fixedly attached to the top of the sliding rack 61. The contact plate 62 completely covers the rain inlet 14 (see fig. 1) of the gutter cover 11 (see fig. 1), the contact block 63 is fixedly connected to the upper surface of the contact plate 62, and the contact plate 62 is completely in contact with the lower surface of the gutter cover 11 (see fig. 1) via the contact block 63. The abutment block 63 is provided so that rainwater can flow into the gutter body 1 (see fig. 1) through a gap between the gutter cover 11 (see fig. 1) and the abutment plate 62.

Meanwhile, the abutting plate 62 shields the driving gear 23, the driving rack 25 and the sliding rack 61 in the fixed frame 5 (see fig. 2), so that rainwater or impurities are prevented from entering the part where the driving gear 23 is meshed with the driving rack 25, and the possibility of jamming of the driving gear 23 is reduced.

During raining, rainwater flows into the drain main body 1 through a gap between the contact plate 62 and the gutter cover 11. The buoyancy of the floating plate 21 by the rainwater and the impact force of the rainwater on the abutting plate 62 are utilized to synchronously drive the transmission shaft 22 to rotate, so that the mud scraper 31 is driven to move.

Referring to fig. 4, the upper surface of the floating plate 21 is provided with an inclined surface 211, and the middle of the inclined surface 211 near the floating plate 21 is the highest point. The upper surface of the floating plate 21 is not easily deposited with sludge by the arrangement of the inclined surface 211, and the sludge is entirely dropped into the bottom of the drainage ditch body 1.

Referring to fig. 4, the lower surface of the floating plate 21 is provided with a drainage surface 212, and the inclination direction of the drainage surface 212 is the same as the flow direction of rainwater, so that in the process of rainwater flowing, the impact of rainwater can also exert an upward impact force on the floating plate 21, thereby making the floating plate 21 float upward more easily.

Referring to fig. 4, the mass of the floating plate 21 is greater than that of the abutting plate 62, so that the abutting plate 62 can abut at the rain inlet 14 (see fig. 1) of the gutter cover 11 (see fig. 1) and can bear a certain weight. When rainwater accumulates in the drainage ditch body 1 (refer to fig. 1), the floating plate 21 floats upwards due to the buoyancy of the rainwater, and the abutting plate 62 is also moved downwards due to the impact of the rainwater and the gravity of the abutting plate 62, so that the floating plate 21 and the abutting plate 62 simultaneously drive the transmission shaft 22 to rotate.

After the rainwater stops, the water level in the drainage ditch body 1 falls, so that the floating plate 21 moves downward, and meanwhile, the rainwater does not impact the abutting plate 62 any more. Since the weight of the floating plate 21 is greater than that of the abutting plate 62, the abutting plate 62 is moved upward to abut at the rain inlet 14 of the gutter cover 11.

Referring to fig. 4, the diameter length of the transmission gear 24 is greater than that of the driving gear 23, so that the driving shaft 22 is rotated by the engagement of the floating plate 21 and the abutting plate 62 with the driving gear 23 to move the driving rack 26 (see fig. 3) engaged with the transmission gear 24 a greater distance.

Referring to fig. 3, evenly distributed has a plurality of mud scraping components 3 and drive assembly 2 in the escape canal main part 1, has shown in this embodiment, and when driving transmission shaft 22 pivoted extreme position through kicking plate 21 and butt plate 62, the distance that transmission rack 26 drove mud scraping component 3 and removed is greater than the interval of adjacent mud scraping component 3.

Make the moving range of scraping mud subassembly 3 have the coincidence of certain degree for scrape mud subassembly 3 and be continuous scrape silt to the coincidence portion, the rethread is close to the adjacent mud subassembly 3 of scraping of drain pipe 12 and shifts to next coincidence portion to the silt of coincidence portion once more, thereby shifts silt to drain pipe 12 mouth.

The implementation principle of the embodiment 1 of the application is as follows: when not raining, the abutting plate 62 abuts against the rain inlet 14, so that the rain inlet 14 is blocked, foreign matters such as external dust and leaves are prevented from entering the drainage ditch main body 1, and a student teacher and the like who move are prevented from dropping a mobile phone or a key into the drainage ditch main body 1.

When the rainwater is large, the rainwater impacts the abutting plate 62 and causes the floating plate 21 to float gradually, so that the driving rack 25 and the sliding rack 61 synchronously drive the transmission shaft 22 to rotate. The driving shaft 22 rotates to drive the scraper 31 to scrape the sludge at the bottom of the drain body 1 toward one end of the drain pipe 12.

When the rainwater is small, the water level of the rainwater in the drainage ditch body 1 gradually decreases, so that the floating plate 21 gradually decreases, the driving rack 25 drives the transmission shaft 22 to rotate reversely at the moment, so that the mud scraping plate 31 resets, and the reset mud scraping plate 31 penetrates through the mud moved by the adjacent mud scraping plate 31.

When the rainwater is larger again, the abutting plate 62 is impacted by the rainwater again, and the floating plate 21 is made to float gradually again, so that the driving rack 25 and the sliding rack 61 synchronously drive the transmission shaft 22 to rotate. The sludge is scraped off again toward the drain pipe 12. The mud-scraping plates 31 are continuously reciprocated by the change of the size of the rainwater, so that the sludge is continuously transferred between the adjacent mud-scraping plates 31, and finally the sludge is scraped to the drain pipe 12, so that the sludge is discharged through the drain pipe 12.

If it is not rainy for a long time, the staff can continuously inject water into the drainage ditch main body 1 while impacting the abutting plate 62 with water through the water inlet pipe by the water pipe with large water pressure. The abutting plate 62 is driven to descend by the pressure of the water in the water pipe, so that the transmission shaft 22 can be driven to rotate, and the sludge in the drainage ditch body 1 is scraped by the bottom sludge scraper 31.

Or, after the drainage ditch main body 1 is filled with a certain amount of water, the abutting plate 62 is pressed down through a plurality of long rods at the same time, and the abutting plate 62 is pressed down through the long rods continuously. The scraper 31 is also constantly driven to scrape sludge at the bottom of the drain main body 1 to the drain pipe 12, thereby discharging the drain main body 1 through the drain pipe 12.

Example 2

Referring to fig. 7, the difference between embodiment 2 and embodiment 1 is that a plurality of scraping teeth 311 are integrally formed on the bottom of the scraper 31, and the bottom of the scraping teeth 311 abuts against the bottom of the drainage ditch body 1. The sludge at the bottom of the drainage ditch body 1 is scraped through the scraping teeth 311, and the scraped sludge is washed by rainwater, so that the sludge at the bottom of the drainage ditch body 1 is cleaned.

The mud scraper 31 of embodiment 1 is suitable for a place where soil is less near a playground, and thus sludge deposited in the drain main body 1 is less, and the mud deposited at the bottom of the drain main body 1 can be scraped off by the mud scraper 31, so that the sludge in the drain main body 1 can be cleaned more cleanly. However, when the amount of sludge near the playground is large, the sludge cannot be completely prevented from falling into the drainage ditch body 1 through the abutting plate 62, so that the sludge in the drainage ditch body 1 is deposited more, and the flat sludge scraping plate 31 cannot scrape the sludge at the bottom of the drainage ditch body 1, and therefore, the scraping teeth 311 are arranged at the bottom of the sludge scraping plate 31, so that the resistance of the sludge at the bottom of the drainage ditch body 1 on the sludge scraping plate 31 is reduced, the sludge at the bottom of the drainage ditch body 1 is scraped, and the scraped sludge is drained into the drainage pipe 12 through the scouring of rainwater.

The implementation principle of embodiment 2 of the present application is as follows: on the more playground of earth section, the bottom of escape canal main part 1 accumulates more silt easily, when the rainwater is great, the rainwater makes the kicking block upwards float, reduces the resistance that scrapes mud board 31 and receive silt through the setting of scraping tooth 311, make and scrape tooth 311 and be convenient for more scrape silt in escape canal main part 1 bottom, during the rethread rainwater will become flexible silt rush into drain pipe 12, thereby accomplish the clearance to escape canal main part 1 bottom silt.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
