DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the utility model discloses a drainage pipe with a switch for drainage of an underpass section.

[0025] The utility model provides Figure 1-3 The shown drainage pipe with a switch for drainage in an underpass section includes a drainage pipe 1 and an inlet pipe 2. A switch valve 21 is fixedly sleeved on the pipe wall of the drainage pipe 1. A connecting rod 3 is fixedly provided between the drainage pipe 1 and the inlet pipe 2. A plurality of baffles 4 arranged in a symmetrical manner are fixedly provided at one end of the drainage pipe 1 close to the inlet pipe 2. A filter screen 5 is provided between the plurality of baffles 4. The filter screen 5 cover is provided on the outside of the pipe mouth of the drainage pipe 1. A plurality of cleaning plates 6 arranged in a symmetrical manner are provided on the surface contact of the filter screen 5. A cleaning belt 7 is fixed between two adjacent cleaning plates 6. The cleaning belt 7 is an elastic belt. A limit plate 19 is slidably penetrated inside the baffle 4. A positioning bolt 20 is threadedly penetrated through the side wall of the baffle 4. The positioning bolt 20 contacts and cooperates with the limit plate 19.

[0026] Before draining, the water inlet pipe 2 is connected to the road drain outlet. When draining, the switch valve 21 is opened and the drain pipe 1 is connected to the external water pump. At this time, the drain pipe 1 can quickly suck the water. At the same time, under the setting of the filter 5, the debris in the water is blocked and cannot enter the drain pipe 1 and damage the water pump. At the same time, multiple cleaning plates 6 can move and drive the cleaning belt 7 to clean the debris along the surface of the filter 5, so that the debris cannot block the surface of the filter 5, so that the drainage work can be carried out stably. After the drainage work is completed, the positioning bolt 20 can be removed to separate the limit plate 19 from the filter 5, and the filter 5 can be taken out for inspection.

[0027] In order to enable the plurality of cleaning plates 6 to move stably during drainage work, as shown in FIG. Figure 1-2As shown, a pushing cleaning mechanism is provided between the multiple cleaning plates 6 and the filter screen 5, and the pushing cleaning mechanism includes a reciprocating screw 8, which is rotatably connected to the surface of the filter screen 5, and a slider 9 is provided on the rod wall thread sleeve, and the outer wall of the slider 9 is hinged with a plurality of push plates 10 arranged in a symmetrical manner. The surface of the filter screen 5 is provided with a plurality of sliding holes arranged in a symmetrical manner, and a fixed rod 11 is fixed inside the sliding hole, and a sliding rod 12 is provided on the rod wall sliding sleeve of the fixed rod 11. The sliding rod 12 is fixed inside the cleaning plate 6, and the push plate 10 is hinged to the cleaning plate 6 at one end away from the slider 9.

[0028] During drainage, the reciprocating screw 8 is driven to drive the slider 9 to move back and forth, and at the same time push the multiple push plates 10. At this time, the multiple cleaning plates 6 are pushed by the push plates 10 under the sliding cooperation of the slide rod 12 and the fixed rod 11, so that the multiple cleaning plates 6 drive the cleaning belt 7 to quickly clean and remove debris along the surface of the filter 5.

[0029] In order to drive the reciprocating screw rod 8 to rotate stably while the drainage work is being carried out, Figure 1-2 As shown, the inner wall of the water inlet pipe 2 is rotatably provided with a rotating rod 13, and the rod wall of the rotating rod 13 is fixedly sleeved with an impeller 14. The pipe wall of the water inlet pipe 2 is provided with a through hole for cooperating with the rotation of the impeller 14. The lower end of the inner wall of the water inlet pipe 2 is fixedly provided with a fixing plate 15, and the interior of the fixing plate 15 is rotatably provided with a vertical rod 16. Both ends of the vertical rod 16 are fixedly provided with a first bevel gear 17, and the rod walls of the rotating rod 13 and the reciprocating screw 8 are fixedly sleeved with a second bevel gear 18, and the two adjacent first bevel gears 17 and the second bevel gears 18 are meshed.

[0030] When the water pump sucks the water, the water entering the drain outlet from the road surface quickly enters the water inlet pipe 2 and is sucked. At this time, under the rapid flow of water, the impeller 14 is pushed to drive the rotating rod 13 to rotate. At the same time, under the support of the vertical rod 16 and the engagement of multiple first bevel gears 17 and second bevel gears 18, the rotating rod 13, the vertical rod 16 and the reciprocating screw 8 rotate at the same time, and the multiple cleaning plates 6 can be driven to perform effective cleaning work while reducing the drive of external energy.

[0031] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
