[0019] S2, expansion: the motor is started to drive the convex surface on the transmission hole to gradually press against the L-shaped rod, and the L-shaped rod 351 is forced to one side to drive the expansion plate, the expansion rod, and the blocking rod to expand outward.

[0022] S5, descent: The hydraulic cylinder is started by the controller to drive the transmission rod to drive the transmission tube and the manhole cover downward.

[0023] Beneficial effects:

[0024] In the present invention, during the continuous reciprocating work, larger garbage can be intercepted and pushed to the vicinity of the port of the drainage hole 11, while smaller garbage flows into the drainage hole with the flow of rainwater. Through the guidance of the transmission hole, larger garbage can be prevented from being blocked at the port of the drainage hole, which can maintain the smoothness of rainwater discharge and facilitate workers' cleaning, thereby improving convenience and practicality.

[0025] In the present invention, in order to prevent leaves and plastics from clogging the leakage holes of the conical leakage plate, the conical leakage plate is provided with a cone, which effectively makes the fallen leaves and plastics automatically collect the leaves according to the angle of the cone and store them at the connection between the conical leakage plate and the transmission cylinder.

[0026] In the present invention, sometimes fallen leaves and plastics may adhere to the inner surface of the conical leakage plate and block the leakage holes of the conical leakage plate. The upward movement of the conical leakage plate and the downward flow of rainwater can be utilized to make the conical leakage plate impact the downwardly flowing rainwater upward, and then the conical angle of the conical leakage plate can effectively allow the leaves and plastics to slide downward and slide downward at the connection between the conical leakage plate and the transmission cylinder. As a result, smaller leaves and plastics can be intercepted to avoid blocking the leakage holes of the conical leakage plate, thereby improving functionality, preventing pollution of rivers or seas by filtering garbage, and improving environmental protection.

[0027] In the present invention, the hydraulic cylinder is started to drive the manhole cover and the conical leak plate to move upward until the upper port of the conical leak plate is located at the upper port of the drainage hole, and the hydraulic cylinder is stopped. At this time, workers can clean up the garbage, which is also convenient for manual cleaning. At the same time, without the obstruction of the expansion rod and the blocking rod, the garbage will flow along the inner surface of the conical leak plate with the rainwater. Therefore, when cleaning the leaves and plastics in the conical leak plate, the leaves and plastics will not fall down to the inner bottom of the drainage hole, thereby further strengthening the protection of the environment.

The transmission rod 23 is forced to move upward, and its transmission tube 41 drives the conical leak plate 42 upward through the transmission of the transmission ball 232. At the same time, the transmission rod 23 drives the motor 25 and the manhole cover 26 upward to move. The manhole cover 26 is forced to slide upward inside the casing 29 through the two guide rods 28, effectively ensuring the vertical upward movement of the manhole cover 26. When the manhole cover 26 gradually moves upward, as long as the blocking rod 356 passes over the port of the drainage hole 11, the hydraulic cylinder 21 can be stopped, which is conducive to realizing automatic drainage.

[0040] In this embodiment, the expansion mechanism 3 includes a first guide circular plate 31 rotatably connected to the upper end of the transmission rod 23, and a plurality of fixed rods 32 are connected to the lower end of the first guide circular plate 31 at equal angles in an annular manner at the upper end of the transmission rod 23, and a second guide circular plate 33 is fixedly connected to one end of the plurality of fixed rods 32, and the second guide circular plate 33 is on the same horizontal line as the first guide circular plate 31, wherein the second guide circular plate 33 and the first guide circular plate 31 have opposite surfaces that form a transmission hole 34.

[0041] In this embodiment, the transmission hole 34 is provided with a plurality of convex surfaces 341 and a plurality of concave surfaces 342, wherein a plurality of expansion components 35 are provided on the plurality of concave surfaces 342, which is conducive to realizing the reciprocating contraction and expansion of the expansion rod 355 and the blocking rod 356.

[0042] In this embodiment, the expansion assembly 35 includes an L-shaped rod 351 that slides in the transmission hole 34, one end of the L-shaped rod 351 is fixedly connected to an expansion plate 352, the middle of the upper end surface of the expansion plate 352 is fixedly connected to a sliding plate 353, the upper end of the sliding plate 353 is slidably matched with a sliding groove 354, and the sliding groove 354 is equiangularly annular and is opened on the lower end surface of the manhole cover 26. The outer side surface of the expansion plate 352 is connected to expansion rods 355 arranged along the length direction, and one end of the expansion rod 355 is fixedly connected to a blocking rod 356. The multiple L-shaped rods 351 located in the transmission hole 34 gradually slide onto the convex surface 341. The L-shaped rods 351 are guided by the convex surface 341, so that the L-shaped rods 351 are forced to drive the expansion plate 352 to one side. The expansion plate 352 is forced to slide to one side through the sliding plate 353 inside the sliding groove 354, so that the expansion plate 352 moves stably to one side. At the same time, the expansion rods 355 and the blocking rods 356 expand outwards, and after being gradually guided by the convex surface 341, they are gradually guided to the concave surface 342. At this time, the expansion rods 355 and the blocking rods 356 gradually return to their original positions. As the transmission hole 34 continues to rotate counterclockwise, The expansion rod 355 and the blocking rod 356 can realize the reciprocating contraction and expansion work. At this time, the garbage in the rainwater is surrounded at the end of the drain hole 11. At this time, the expansion rod 355 and the blocking rod 356 work reciprocatingly to push the garbage around the end of the drain hole 11 outward. In the continuous reciprocating work, larger garbage can be intercepted and pushed to the vicinity of the end of the drain hole 11, while smaller garbage flows into the drain hole 11 with the flow of rainwater, which is beneficial to prevent larger garbage from being blocked at the end of the drain hole 11, maintain the smoothness of rainwater discharge, and facilitate workers' cleaning, thereby improving convenience and practicality.

[0043] In this embodiment, the up and down reciprocating mechanism 4 includes a transmission cylinder 41, a through hole 411 is opened in the middle of the top of the transmission cylinder 41, and the inside of the through hole 411 is slidably matched with the upper end of the transmission rod 23, and the transmission rod 23 is inserted in the middle of the transmission cylinder 41, wherein a transmission ball 232 is fixedly connected to one side of the middle of the transmission rod 23 located inside the transmission cylinder 41, and the transmission ball 232 has a lifting ring groove 412 slidingly matched on the outside of the transmission ball 232, and the lifting ring groove 412 is opened on the inner side of the transmission cylinder 41, and a conical leak plate 42 is fixedly connected to the outside of the lower end of the transmission cylinder 41, and the lower end surface of the transmission cylinder 41 is connected to the first limit rod 43 and the second limit rod 44. The conical leak plate 42 has been driven by the motor 25, and the transmission rod 25 driven by the force drives the transmission ball 232 to slide counterclockwise inside the lifting ring groove 412, and the T-shaped groove 231 rotates counterclockwise on the outside of the T-shaped column 221. When the transmission ball 232 gradually slides to the high end of the lifting ring groove 412, the transmission cylinder 41 is forced to gradually slide downward to the lower end of the transmission rod 23 through the through hole 411, and at this time, it also moves downward with the conical leak plate 42. At the same time, the first limiting rod 43 and the second limiting rod 44 slide downward inside the first limiting hole 451 and the second limiting hole 461. The limiting rod 44 gradually slides to the end of the lifting ring groove 412 after the transmission ball 232 slides over the high end of the lifting ring groove 412, so that the transmission cylinder 41 and the conical leakage plate 42 move upward, and can realize reciprocating up and down work, so that the fallen garbage is always located at the inner bottom of the conical leakage plate 42, and the rainwater flows downward through the leakage holes on the conical leakage plate 42. In order to prevent leaves and plastics from clogging the leakage holes of the conical leakage plate 42, the conical leakage plate 42 is provided with a cone, which effectively makes the fallen leaves and plastics automatically gather the leaves according to the angle of the cone, and store them at the connection between the conical leakage plate 42 and the transmission cylinder 41. Sometimes fallen leaves and plastics may adhere to the inner surface of the conical leakage plate 42 and clog the leakage holes of the conical leakage plate 42. The upward movement of the conical leakage plate 42 and the downward flow of rainwater can be used to make the conical leakage plate 42 impact the downward flowing rainwater upward, and then the conical angle of the conical leakage plate 42 can effectively allow the leaves and plastics to slide downward and slide downward at the connection between the conical leakage plate 42 and the transmission cylinder 41. As a result, smaller leaves and plastics can be intercepted to avoid clogging the leakage holes of the conical leakage plate 42, thereby improving functionality, preventing pollution of rivers or seas by filtering garbage, and improving environmental protection.

[0044] In this embodiment, the lower end of the first limiting rod 43 slides in the first limiting hole 451 provided on one side of the first limiting plate 45, one side of the first limiting plate 45 is fixed to the inner side of the lower end of the drain hole 11, and the lower end of the second limiting rod 44 slides in the second limiting hole 461 provided on one side of the second limiting plate 46, one side of the second limiting plate 46 is fixed to the inner side of the lower end of the drain hole 11. This ensures that the transmission cylinder 41 moves vertically upward.

[0045] In this embodiment, the outer side surface of the upper end of the conical drain plate 42 is sleeved on the inner upper part of the drain hole 11. Without the obstruction of the expansion rod 355 and the blocking rod 356, the garbage will flow along the inner surface of the conical drain plate 42 with the rainwater, so that leaves and plastics will not fall down to the inner bottom of the drain hole 11, thereby enhancing the protection of the environment.

[0046] A method for using an automatic drainage system for a municipal road, the specific method steps are as follows:

[0047] S1, ascending: the hydraulic cylinder 21 is activated by the controller to drive the transmission rod 23 to drive the transmission cylinder 41 and the manhole cover 26 upward. The manhole cover 26 is forced to slide upward inside the casing 29 through the two guide rods 28, effectively ensuring the vertical upward movement of the manhole cover 26;

[0048] S2, expansion: the motor 25 is started to drive the convex surface 341 on the transmission hole 34 to gradually press against the L-shaped rod 351, and the L-shaped rod 351 is forced to one side to drive the expansion plate 352, the expansion rod 355, and the blocking rod 356 to expand outward, and after the convex surface 341 is gradually guided, it is gradually guided to the concave surface 342. At this time, the expansion rod 355 and the blocking rod 356 gradually return to their original positions, and then the expansion rod 355 and the blocking rod 356 are reciprocated. The contraction and expansion work can be achieved, which can prevent large garbage from clogging the end of the drainage hole 11, maintain the smoothness of rainwater discharge, and also facilitate workers to clean;

[0049] S3, reciprocating up and down: the transmission ball 232 is driven by the motor 25 to slide counterclockwise inside the lifting ring groove 412. When the transmission ball 232 gradually slides to the upper end of the lifting ring groove 412, the conical leak plate 42 moves downward. After the transmission ball 232 slides beyond the upper end of the lifting ring groove 412, it gradually slides to the lower end of the lifting ring groove 412, so that the transmission cylinder 41 and the conical leak plate 42 move upward, and the reciprocating up and down work can be realized, so that the fallen leaves and plastics are automatically collected according to the angle of the cone, and stored at the connection between the conical leak plate 42 and the transmission cylinder 41;

[0050] S4, cleaning: when too much garbage is intercepted at the bottom of the conical leakage plate 42, the motor 25 is stopped, and the hydraulic cylinder 21 is started to drive the manhole cover 26 and the conical leakage plate 42 to move upward until the upper end of the conical leakage plate 42 is located at the upper end of the drainage hole 11, and the hydraulic cylinder 21 is stopped. At this time, workers clean up the garbage, which is convenient for manual cleaning;

[0051] S5, descent: The hydraulic cylinder 21 is started by the controller to drive the transmission rod 23 to drive the transmission tube 41 and the manhole cover 26 downward. Before this, the expansion rod 355 and the blocking rod 356 are retracted to the original position. When the manhole cover 26 is completely closed at the upper end of the drainage hole 11, the lower end of the transmission plate 27 is embedded in the overlap groove 12, and the hydraulic cylinder 21 is stopped to realize automatic drainage.

[0052] The specific working principle of the present invention includes the following process:

[0053] First, in heavy rain, the hydraulic cylinder 21 is started by the controller to drive the lifting rod 22 to drive the transmission rod 23 upward. The transmission rod 23 is forced to move upward, and its transmission tube 41 is driven by the transmission ball 232 to move the conical leaking plate 42 upward. At the same time, the transmission rod 23 drives the motor 25 and the manhole cover 26 upward to move. The manhole cover 26 is forced to slide upward inside the casing 29 through the two guide rods 28. When the manhole cover 26 gradually moves upward, the hydraulic cylinder 21 can be stopped as long as the blocking rod 356 passes over the port of the drainage hole 11. At this time, the motor 25 is started to drive the rotating shaft 24 and the transmission rod 23 to drive the first guide circular plate 31, the fixed rod 32, and the second guide circular plate 33 to rotate counterclockwise. The multiple L-shaped rods 351 located in the transmission hole 34 gradually slide onto the convex surface 341. The L-shaped rods 351 are guided by the convex surface 341, so that the L-shaped rods 351 are The force drives the expansion plate 352 to one side, and the expansion plate 352 is forced to slide to one side through the sliding plate 353 inside the sliding groove 354. At the same time, the expansion rod 355 and the blocking rod 356 expand outward, and after the convex surface 341 is gradually guided, they are gradually guided to the concave surface 342. At this time, the expansion rod 355 and the blocking rod 356 gradually return to their original positions, and then the expansion rod 355 and the blocking rod 356 can realize the reciprocating contraction and expansion work. At this time, the garbage in the rainwater is surrounded by the port of the drainage hole 11. At this time, the expansion rod 355 and the blocking rod 356 work reciprocatingly to push the garbage around the port of the drainage hole 11 outward. In the continuous reciprocating work, larger garbage (such as larger branches and larger plastics, etc.) can be intercepted and pushed to the vicinity of the port of the drainage hole 11, while smaller garbage flows into the drainage hole 11 with the flow of rainwater.

[0054] After the smaller garbage flows into the drainage hole 11 with the flow of rainwater, it flows down to the inner surface of the conical leakage plate 42. At this time, the conical leakage plate 42 has been driven by the motor 25, and its stressed transmission rod 25 drives the transmission ball 232 to slide counterclockwise inside the lifting ring groove 412, and the T-shaped groove 231 rotates counterclockwise on the outside of the T-shaped column 221. When the transmission ball 232 gradually slides to the high end of the lifting ring groove 412, the transmission cylinder 41 is forced to gradually slide downward to the lower end of the transmission rod 23 through the through hole 411. At this time, it also moves downward with the conical leakage plate 42. At the same time, the first limiting rod 43 and the second limiting rod 44 slide downward inside the first limiting hole 451 and the second limiting hole 461. After the transmission ball 232 slides past the high end of the lifting ring groove 412, it gradually slides to the end of the lifting ring groove 412, so that the transmission cylinder 41 and the conical leakage plate 42 move upward. The cone 42 is provided with a cone, which can automatically collect the fallen leaves and plastics along the angle of the cone, and store them at the connection between the cone 42 and the transmission cylinder 41. Sometimes, the fallen leaves and plastics will adhere to the inner surface of the cone 42 and be blocked at the leakage holes of the cone 42. The cone 42 can move upward and the rainwater can flow downward to make the cone 42 impact the downward-flowing rainwater upward, and then the cone angle of the cone 42 can be used to make the leaves and plastics slide downward and slide downward at the connection between the cone 42 and the transmission cylinder 41.

[0055] When too much garbage is intercepted at the bottom of the conical leakage plate 42, the motor 25 is stopped and the hydraulic cylinder 21 is started to drive the manhole cover 26 and the conical leakage plate 42 to move upward until the upper port of the conical leakage plate 42 is located at the upper port of the drainage hole 11, and the hydraulic cylinder 21 is stopped. At this time, workers can clean up the garbage, which is also convenient for manual cleaning. At the same time, without the obstruction of the expansion rod 355 and the blocking rod 356, the garbage will flow along the inner surface of the conical leakage plate 42 with the rainwater. Therefore, when cleaning the leaves and plastics in the conical leakage plate 42, the leaves and plastics will not fall down to the inner bottom of the drainage hole 11, thereby further strengthening the protection of the environment.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
