Description

Technical Field

[0001] The present invention relates to the technical field of municipal engineering, and particularly to a manhole cover for preventing waterlogging. Background Art

[0002] With the acceleration of the urbanization process, the underground pipeline system has gradually become complex, and the importance of manhole covers has become increasingly prominent. Since the installation position of the manhole cover is often lower than the surrounding ground, there is often a certain amount of accumulated water on the manhole cover. This not only affects the walking of pedestrians, increasing the risk of pedestrians falling, but also requires municipal personnel to perform drainage operations, increasing their workload. Seriously, the accumulated water on the manhole cover may also affect traffic safety. Currently, several small holes for drainage are designed on the manhole cover, but they are extremely easy to be blocked by various sundries, resulting in unsmooth drainage. And once the accumulated water is too much, the manhole cover cannot be opened in time for drainage. Summary of the Invention

[0018] (III) Advantageous Effects

[0019] Compared with the prior art, the present invention provides a manhole cover for preventing water accumulation, having the following advantageous effects:

[0020] This manhole cover for preventing water accumulation is used by the mutual cooperation of a manhole cover assembly, a cleaning assembly, a driving assembly, and a transmission control assembly.

[0021] When there is a small amount of accumulated water in the outside world and the water leakage holes above the manhole cover are blocked by impurities. At this time, the motor rotates counterclockwise, driving the first transmission shaft to rotate counterclockwise, and finally driving the bevel gears II of the transmission control assemblies on the left and right to rotate clockwise and counterclockwise. At this time, the directions of the internal ratchet teeth in the two transmission control assemblies on the left and right are opposite. Therefore, the bevel gears II on both sides drive the second transmission shaft to rotate, thereby driving the cleaning components in the cleaning assemblies on both sides to swing towards the bottom of the manhole cover. At this time, the first lifting surface and the second lifting surface do not contact each other. The cleaning component gradually rotates in the horizontal plane to the bottom of the water leakage hole of the manhole cover. When the cleaning component approaches the bottom of the water leakage hole, the first lifting surface and the second lifting surface contact, thereby lifting the cleaning component so that the cleaning head aligns with the water leakage hole and jacks upwards, pushing away the blocked impurities to achieve the cleaning of the water leakage hole.

[0022] When there is a large amount of accumulated water in the outside world, at this time, the drainage through the water leakage holes is not sufficient to drain the accumulated water completely. At this time, the motor rotates clockwise. At this time, the bevel gears II of the transmission control assemblies on the left and right are in an idle rotation state because they cannot engage with the internal engaging teeth, and the cleaning components will not make a jacking action. However, the bevel gear II in the transmission control assembly on the flipping mechanism engages with the engaging teeth to drive the third transmission shaft to rotate, causing the slider to descend, and then the transmission plate drives the connecting end to descend, and finally drives the manhole cover to open around the rotating shaft, enabling the large amount of accumulated water to be quickly drained.

[0023] Thus, the effects of being able to clean the drainage holes on the manhole cover in a timely manner and opening the manhole cover in a timely manner for drainage when there is too much accumulated water are achieved. Description of the Drawings

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1-8 , a manhole cover 11 for preventing water accumulation, which includes a manhole cover assembly 1, a cleaning assembly 2 and a driving assembly 3. The manhole cover assembly 1 includes a manhole cover 11, and a water leakage hole 111 is provided on the manhole cover 11. The manhole cover 11 can be opened under the drive of the driving assembly 3 to drain a large amount of accumulated water.

[0039] Cleaning assemblies 2 are respectively arranged on both sides of the manhole cover assembly 1. The cleaning assemblies 2 on both sides respectively correspond to two water leakage holes 111 on the manhole cover 11. The cleaning assembly 2 can push the magazines deposited in the water leakage holes 111 from the outside to the inside and upwards under the drive of the driving assembly 3, always keeping the water leakage holes 111 unblocked and ensuring the smooth drainage of a small amount of accumulated water.

[0040] A base 12 is arranged on the outer side of the manhole cover 11. The base 12 is fixedly installed on the ground. The base 12 is the basis for installing the manhole cover 11. It is fixedly installed on the ground to provide stable support for the manhole cover 11. One side of the manhole cover 11 is rotatably connected to the base 12 through a rotating shaft 14. The rotating shaft 14 is a component connecting the manhole cover 11 and the base 12. It allows the manhole cover 11 to rotate within a certain range, ensuring that the manhole cover 11 can be rotated and opened by the driving assembly 3 subsequently. A connection end 13 is also provided on the manhole cover 11. The connection end 13 is connected to the flipping mechanism 32 and is used to pull the manhole cover 11 to rotate around the rotating shaft 14 to achieve opening and closing.

[0041] The cleaning assembly 2 includes a mounting seat 21. A jacking device 22, a second chute 29 and a fixing groove 211 are provided on the mounting seat 21. The fixing groove 211 is used for fixedly installing a second cam 28. The second cam 28 is a fixed part. A first cam 27 is rotatably arranged in the middle of the second cam 28. The first cam 27 is a rotating part. In addition, the first cam 27 is cooperated above the second cam 28 by its own gravity. A ring groove 273 is provided in the middle of the first cam 27. A lifting support rod 24 is rotatably arranged in the ring groove 273. The lifting support rod 24 is also slidably arranged in the second chute 29. The first cam 27 is a rotating component, while the lifting support rod 24 is a non-rotating component and only moves up and down. Therefore, the lifting support rod 24 is arranged in a ring around the ring groove 273. When the first cam 27 rotates, the lifting support rod 24 will not rotate together. However, when the first cam 27 moves up and down, the first cam 27 can drive the lifting support rod 24 to move up and down. In order to limit the up and down movement direction of the lifting support rod 24, the lifting support rod 24 is slidably arranged up and down in the second chute 29.

[0042] The lower surface of the first cam 27 is provided with a first lifting surface 272, and the upper surface of the second cam 28 is provided with a second lifting surface 281. The first lifting surface 272 and the second lifting surface 281 compensate for each other. When the first lifting surface 272 and the second lifting surface 281 are misaligned with each other, the first cam 27 and the second cam 28 rotate closely together, driving the cleaning component 25 with a height lower than that of the manhole cover 11 to rotate to the bottom of the water leakage hole 111 of the manhole cover 11. At this time, the height of the cleaning head 251 is also lower than the water leakage hole 111 of the manhole cover 11, facilitating the movement of the cleaning head 251 below the water leakage hole 111. When the cleaning head 251 is about to reach below the water leakage hole 111, the first lifting surface 272 and the second lifting surface 281 come into contact with each other. Due to the continuous rotation of the first cam 27, the first lifting surface 272 is lifted upward by the second lifting surface 281, thereby increasing the height of the first cam 27, further increasing the height of the swing rod 23 pressed in the annular gap 273, and finally lifting the cleaning head 251 of the cleaning component 25 upward. When the cleaning head 251 rises, it inserts into the water leakage hole 111 of the manhole cover 11, pushing open the debris blocking the water leakage hole 111, making the water leakage hole 111 unobstructed and realizing the normal drainage function.

[0043] The bottom of the rotating shaft 271 meshes with the fourth bevel gear 261 of the second transmission shaft 26. One end of the second transmission shaft 26 extending out of the mounting seat 21 is provided with a transmission control component 4. The rotating shaft 271 is fixedly connected to the first cam 27 and can drive the first cam 27 to rotate through the drive of the second transmission shaft 26.

[0044] The abutting device 22 includes a first chute 221 fixedly arranged on the mounting seat 21. A rod sleeve 222 is slidably arranged in the first chute 221. The arrangement of the first chute 221 enables the sleeve rod to slide up and down in the chute to correspond to the up and down movement of the first cam 27. A push rod 224 is slidably arranged inside the rod sleeve 222. A first spring 223 is arranged between the push rod 224 and the rod sleeve 222. The arrangement of the first spring 223 enables the push rod 224 located inside the rod sleeve 222 to be always pushed outwards by the first spring 223, so that one end of the swing rod 23 can always be pressed by the push rod 224 in the annular gap 273 of the first cam 27, thereby ensuring that the swing rod 23 can be driven to move up and down during the up and down movement of the first cam 27 and preventing the swing rod 23 from disengaging from the first cam 27.

[0045] A swing rod 23 is placed on the lifting support rod 24. A rotary lifting rod 231 is arranged in the middle of the swing rod 23, and the rotary lifting rod 231 is arranged on the mounting base 21. The main part of the swing rod 23 is placed on the lifting support rod 24. Since the swing rod 23 is a rotating part, the function of the lifting support rod 24 is only to support the swing rod 23. The rotary lifting rod 231 is used as the rotating shaft 271 of the swing rod 23. When the first cam 27 rotates, one end of the swing rod 23 pressed against the first cam 27 will move accordingly, and the other end of the swing rod 23, that is, the end provided with the cleaning component 25, will rotate at a certain angle around the rotary lifting rod 231.

[0046] The cleaning component 25 includes a swing seat 253 fixedly arranged at the other end of the swing rod 23. A cleaning head 251 is rotatably arranged on the swing seat 253. Two second springs 252 are arranged between the bottom of the cleaning head 251 and the swing rod 23, and the two second springs 252 are arranged on both sides of the swinging direction of the cleaning head 251. In order to ensure that the cleaning head 251 can reach the bottom of the manhole cover 11 more stably and prevent the top of the cleaning head 251 from being blocked by the edge of the manhole cover 11 during the process of entering and rising from the bottom of the manhole cover 11, when the cleaning head 251 rises, once the cleaning head 251 touches the lower part of the edge of the manhole cover 11, the cleaning head 251 will swing to one side, so that the cleaning head 251 can smoothly enter the bottom of the manhole cover 11. After the cleaning head 251 enters the bottom of the manhole cover 11, the springs on both sides of the bottom of the cleaning head 251 reset, so that the cleaning head 251 returns to the upright state and then continues to rise to push out the impurities in the water leakage hole 111 of the manhole cover 11.

[0047] The driving assembly 3 includes a motor bracket 311 and a flipping mechanism 32. A motor 31 is installed on the motor bracket 311. A first transmission shaft 33 is arranged on the motor 31. Two first bevel gears 331 are respectively arranged at both ends of the first transmission shaft 33, and the two first bevel gears 331 are respectively engaged with the transmission control assemblies 4 on the second transmission shafts 26 of the two cleaning assemblies 2 on both sides. A third bevel gear 332 is arranged in the middle of the first transmission shaft 33. The above is the prior art and will not be elaborated here.

[0048] The flipping mechanism 32 includes a bearing seat fixing plate 321. A second bearing seat 323 is arranged on the bearing seat fixing plate 321. One end of a third transmission shaft 322 is installed on the second bearing seat 323. A slider 324 is arranged on the third transmission shaft 322. A transmission plate 325 is rotatably connected to the slider 324. The transmission plate 325 is rotatably connected to the connection end 13. A transmission control assembly 4 is arranged at the other end of the third transmission shaft 322, and the transmission control assembly 4 is engaged with the third bevel gear 332. The above is the prior art and will not be elaborated here.

[0049] The drive control assembly 4 includes a fixed seat 42. Inside the fixed seat 42, a second bevel gear 41 is rotatably arranged. An internal ratchet 46 is arranged on the inner ring surface of the second bevel gear 41 inside the fixed seat 42. Inside the second bevel gear 41, a drive shaft sleeve 43 is rotatably arranged. A locking tooth 44 is fixedly arranged inside the drive shaft sleeve 43. A torsion spring 45 is arranged between the locking tooth 44 and the drive shaft sleeve 43. The locking tooth 44 cooperates with the internal ratchet 46. In this design, since there is only one motor 31 and the rotation direction of the motor 31 is fixed, and the cleaning assemblies 2 on both left and right sides are mirror - set with inconsistent swinging directions of their swing rods 23, it is necessary to install the drive control assembly 4 to limit its rotation direction. In addition, a drive control assembly 4 is also arranged on the flipping mechanism 32. Through this component, when the motor 31 rotates counter - clockwise, the cleaning assembly 2 cleans the water leakage holes 111, corresponding to the situation where there is less accumulated water on the road surface and the water leakage holes 111 are blocked; when the motor 31 rotates clockwise, the cleaning assembly 2 does not move, and the flipping mechanism 32 opens the manhole cover 11, corresponding to the situation where there is a large amount of accumulated water on the road surface. The drive control assembly 4 is formed by the mutual nesting of the fixed seat 42, the second bevel gear 41, and the drive shaft sleeve 43, and all three are rotatably connected to each other.

[0050] When the second bevel gear 41 drives the internal ratchet 46 therein to rotate along the locking tooth 44, the locking tooth 44 is not stuck by the internal ratchet 46, and the locking tooth 44 always stays in place and thus does not drive the drive shaft sleeve 43 to rotate; when the second bevel gear 41 drives the internal ratchet 46 therein to rotate against the locking tooth 44, the internal ratchet 46 catches the locking tooth 44, and the internal ratchet 46 drives the locking tooth 44 to further drive the drive shaft sleeve 43 to rotate.

[0051] The drive shaft sleeve 43 is fixedly connected to the second drive shaft 26. The drive control assemblies 4 are respectively installed on the second drive shafts 26 of the left and right cleaning assemblies 2, and the drive shaft sleeve 43 is fixedly connected to the second drive shaft 26, so as to realize that when the motor 31 rotates counter - clockwise, the swing rod 23 swings, and when the motor 31 rotates clockwise, the second bevel gear 41 is in an idling state and the swing rod 23 does not move. In addition, due to the arrangement of the first bevel gears 331 on both sides of the first drive shaft 33, the directions of the internal ratchets 46 inside the drive control assemblies 4 on both sides are opposite.

[0052] The drive shaft sleeve 43 is fixedly connected to the third drive shaft 322. The drive control assembly 4 is also installed on the third drive shaft 322, and the second bevel gear 41 on this drive control assembly 4 meshes with the third bevel gear 332 on the first drive shaft 33. When the motor 31 rotates counter - clockwise, this second bevel gear 41 is in an idling state, that is, the manhole cover 11 will not be opened, and at this time the cleaning assembly 2 is cleaning the water leakage holes 111; when the motor 31 rotates clockwise, the cleaning assembly 2 is hidden on both sides outside the manhole cover 11, the manhole cover 11 is opened, and a large amount of accumulated water is discharged, so as to ensure that the cleaning assembly 2 will not be washed away by a large amount of accumulated water.

[0053] Working principle: When there is a small amount of accumulated water in the external environment and the water leakage holes 111 above the manhole cover 11 are blocked by impurities. At this time, the motor 31 rotates counterclockwise, driving the first transmission shaft 33 to rotate counterclockwise, and finally driving the bevel gears II 41 of the left and right transmission control components 4 to rotate clockwise and counterclockwise. At this time, the directions of the internal ratchet teeth 46 inside the left and right transmission control components 4 are opposite. Therefore, the bevel gears II 41 on both sides drive the second transmission shaft 26 to rotate, thereby driving the cleaning components 2 on both sides to swing the cleaning parts 25 towards the bottom of the manhole cover 11. At this time, the first lifting surface 272 and the second lifting surface 281 do not contact each other. The cleaning part 25 gradually rotates in the horizontal plane to the bottom of the water leakage hole 111 of the manhole cover 11. When the cleaning part 25 approaches the bottom of the water leakage hole 111, the first lifting surface 272 and the second lifting surface 281 contact each other, thereby lifting the cleaning part 25, so that the cleaning head 251 aligns with the water leakage hole 111 and jacks upward, pushing away the blocked impurities and realizing the cleaning of the water leakage hole 111.

[0054] When there is a large amount of accumulated water in the external environment, at this time, the drainage through the water leakage holes 111 is not sufficient to drain the accumulated water completely. At this time, the motor 31 rotates clockwise. At this time, the bevel gears II 41 of the left and right transmission control components 4 are in an idling state because they cannot engage with the internal ratchet teeth 44, and the cleaning parts 25 will not make a jacking action. However, the bevel gears II 41 in the transmission control component on the flipping mechanism 32 engage with the ratchet teeth 44 to drive the third transmission shaft 322 to rotate, causing the slider 324 to descend, and then the transmission plate 325 drives the connection end 13 to descend, and finally drives the manhole cover 11 to open around the rotating shaft 14, so that a large amount of accumulated water can be quickly drained.
