Description

Technical Field

[0001] This invention relates to the field of manhole cover technology, and in particular to an intelligent manhole cover with waterproof and shock-absorbing functions. Background Technology

[0002] As we all know, many facilities are placed underground during urban construction for aesthetic and traffic convenience, such as power cables, gas pipes, and water pipes. For the convenience of construction, maintenance, and repair, these underground facilities are equipped with a manhole at regular intervals on the ground surface. The manhole contains a well body, and the well body is equipped with a manhole cover to prevent people or objects from falling in.

[0003] In the existing technology, the waterproof effect of manhole covers is not good enough. A single waterproofing treatment of the manhole cover cannot meet the sealing requirements in some special situations. For example, when the water level exceeds the height of the manhole cover and submerges it, water will enter the internal space of the well, affecting the normal use of some facilities.

When the water level near the manhole opening exceeds the height of the base, water can enter the manhole from the side of the opening. The water will first pass through the base and then enter the manhole. At this time, the drainage pipe connected to the bottom of the base will guide the water into the sewer pipe. At this time, the second sealing component also blocks the water to prevent it from entering the manhole. The use of multiple seals and drainage pipes can ensure that water does not enter the manhole under different conditions, keep the internal space of the manhole dry, and protect the facilities inside the manhole.

[0070] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0071] Example 1

[0072] like Figure 1-15 As shown in the figure, this embodiment proposes an intelligent manhole cover with waterproof and shock-absorbing functions, including a manhole wall 1, a manhole base 2, a manhole cover 3, and a lifting drive component 4. The manhole wall 1 is set in concrete on all four sides, and a ladder is installed on the manhole wall 1. The manhole base 2 is installed on the manhole wall 1, and the manhole cover 3 is hinged to the manhole base 2. The fixed end of the lifting drive component 4 is hinged to the manhole wall 1, and the telescopic end of the lifting drive component 4 is hinged to the manhole cover 3.

[0073] It also includes drainage mechanisms;

[0074] The drainage mechanism includes,

[0075] The sealing assembly comprises two parts: a first sealing assembly and a second sealing assembly. The sealing assembly prevents water from entering the interior of the well wall 1.

[0076] The drainage pipe 8 is connected to the bottom of the well base 2 via a bend. The drainage pipe 8 is lower than the bottom of the well base 2. The drainage pipe 8 allows water entering the well base 2 to flow out. The drainage pipe 8 is arranged in a rectangular pattern and is installed around the concrete around the well wall 1. The outlet end of the drainage pipe 8 is connected to a sewer pipe.

[0077] In this embodiment, when the manhole cover 3 is installed, its base 2 is slightly higher than the ground. When the water level near the well opening does not reach the height of the base 2, water can only enter the well from above the manhole cover 3. At this time, the first sealing component and the base 2 cooperate to block the water from entering. When the water level near the well opening exceeds the height of the base 2, water can enter the well from the side of the well opening. The water will pass through the base 2 before entering the well. At this time, the drainage pipe 8 connected to the bottom of the base 2 will guide the water into the sewer pipe. At this time, the second sealing component also blocks the water to prevent water from entering the well. The use of multiple seals and drainage pipe 8 can ensure that water will not enter the well under different conditions, keep the internal space of the well dry, and protect the facilities inside the well.

[0078] Example 2

[0079] Based on the first specific implementation method, such as Figure 4-7 As shown, the well base 2 is divided into inner and outer layers. The height of the upper surface of the outer layer is higher than that of the upper surface of the inner layer. The inner layer of the well base 2 has a rectangular groove and a right-angled trapezoidal groove in the horizontal direction. The inner layer of the well base 2 has several cylindrical water flow channels in the vertical direction and is connected to the drainage pipe 8 through a bend. The upper half of the rectangular groove of the well base 2 away from the concrete has an oblique flare.

[0080] The first sealing assembly includes,

[0081] The upper cover plate 5 is fixed to the upper surface of the manhole cover 3. When the manhole cover 3 is closed, the upper cover plate 5 contacts the outer upper surface of the manhole seat 2, and the bottom surface of the manhole cover 3 contacts the inner upper surface of the manhole seat 2.

[0082] In this embodiment, the manhole cover 3 is closed, and the upper cover plate 5 contacts the outer upper surface of the manhole seat 2. When the water level is not high enough to reach the height of the manhole seat 2, water can only enter the well from above the manhole cover 3. For example, when it rains, the water will first fall onto the upper cover plate 5. At the same time, the upper cover plate 5 and the manhole seat 2 have a certain contact area, thereby ensuring that water will not enter the well and achieving the function of blocking most of the water.

[0083] Example 3

[0084] Based on the second specific implementation method, such as Figure 10-11 As shown, the second sealing assembly includes,

[0085] A first sealing ring 7 is installed on the lower surface of the manhole cover 3, and the lower surface has a protrusion.

[0086] The second sealing ring 19 is installed on the well base 2. When the well cover 3 is closed, the protruding part of the first sealing ring 7 contacts the side of the second sealing ring 19.

[0087] The lower base plate 6 is installed on the lower surface of the manhole cover 3. When the manhole cover 3 is closed, the lower base plate 6 is inserted between the manhole wall 1.

[0088] In this embodiment, when the water level is higher than that of the well seat 2, water flows into the well. At this time, when the water flows through the well seat 2, the rectangular groove and water flow channel of the inner layer of the well seat 2 guide the water through the bend pipe into the drainage pipe 8, and then discharge it into the sewer pipe through the drainage pipe 8. When the well cover 3 is closed, the first sealing ring 7 and the second sealing ring 19 are in a state of mutual compression, and water cannot flow through the first sealing ring 7 and the second sealing ring 19 into the channel between the well wall 1, thereby keeping the internal space of the well dry. By adopting this multiple sealing and drainage pipe 8, the use of the well cover 3 can meet the needs of different situations, ensuring that the internal space of the well always maintains a relatively dry environment.

[0089] Example 4

[0090] Based on the third specific implementation method, such as Figure 4-9 As shown,

[0091] The drainage mechanism also includes an anti-clogging component, which includes...

[0092] There are two first sliding rods 9, arranged symmetrically. Each first sliding rod 9 is slidably positioned on the middle of the opposite side of the well base 2 where the well cover 3 is not installed.

[0093] There are two first connecting frames 10, and each of the two first connecting frames 10 is slidably connected to one of the two first sliding rods 9.

[0094] Two first cover plates 11 are provided, each mounted on one of the two first connecting frames 10. The first cover plates 11 are slidably disposed in the right-angled trapezoidal groove of the well base 2.

[0095] The second sliding rod 15, there are four of them, and the two sets of the two second sliding rods 15 are slidably disposed on the opposite side of the well base 2 where the well cover 3 is not installed.

[0096] Four limiting frames 16 are provided, and the four limiting frames 16 are respectively installed on the four second sliding rods 15. The limiting frames 16 are arranged at an angle.

[0097] The third sliding rod 17, of which four are provided, are arranged in pairs, with the two pairs of third sliding rods 17 slidably disposed on the opposite side of the well base 2 where the well cover 3 is installed. The first end of the third sliding rod 17 is slidably connected to the limiting frame 16.

[0098] The second mounting frame 33, of which eight are provided, is divided into four groups. Two groups of the second mounting frames 33 are respectively mounted on two of the first cover plates 11. The two second mounting frames 33 mounted on the first cover plates 11 are symmetrically mounted on both sides of the first cover plates 11. The four groups of second mounting frames 33 are alternately and slidably connected to the two groups of second sliding rods 15 and the two groups of third sliding rods 17.

[0099] The second cover plate 34 is provided in two. The two second cover plates 34 are respectively installed on the other two sets of the four sets of the second mounting frames 33. The second cover plate 34 is slidably disposed in the right-angled trapezoidal groove of the well base 2.

[0100] The anti-blocking component also includes,

[0101] Two driven blocks 13 are provided, and the two driven blocks 13 are respectively installed on the opposing ends of the two first sliding rods 9. The height of the upper surface of the driven block 13 gradually decreases from the side closer to the first sliding rod 9 to the side farther away from the first sliding rod 9.

[0102] The elastic telescopic rod 12 is provided in two sets, with each set containing two symmetrical elastic telescopic rods 12. The two sets of elastic telescopic rods 12 are symmetrically installed on the opposite side of the well base 2 where the well cover 3 is not installed. The telescopic ends of the elastic telescopic rods 12 are connected to the first sliding rod 9.

[0103] Two pressure blocks 14 are provided and are symmetrically installed on the manhole cover 3. When the manhole cover 3 is closed, the pressure blocks 14 press the driven block 13.

[0104] In this embodiment, when the manhole cover 3 is closed, the two pressure blocks 14 move together with the manhole cover 3, and the two pressure blocks 14 press down on the two driven blocks 13 respectively, thereby causing the two driven blocks 13 to move away from each other.

[0105] When the manhole cover 3 is open, gravel, leaves, and soil may enter the rectangular groove and water channel of the manhole seat 2, causing blockage. Therefore, when the manhole cover 3 is opened, the pressure block 14 moves with the manhole cover, moving away from the driven block 13. This allows the compressed elastic telescopic rod 12 to extend. The extension of the elastic telescopic rod 12 causes the first sliding rod 9 to slide towards the center of the manhole seat 2, which in turn causes the first connecting frame 10 to slide towards the center of the manhole seat 2. This slides the first cover plate 11 out of the right-angled trapezoidal groove of the manhole seat 2 to the upper part of the rectangular groove of the manhole seat 2. The upper surface of the first cover plate 11 is flush with the upper surface of the inner layer of the manhole seat 2, thus covering the rectangular groove on the first opposite side of the inner layer of the manhole seat 2. When the first cover plate 11 moves, the two sets of second mounting frames 33 mounted on it move synchronously. The movement of the second mounting frames 33 causes the two sets of second sliding rods 15 to move closer to each other. The limiting frame 16 moves synchronously with the second sliding rods 15. The movement of the second sliding rods 15 causes the two sets of third sliding rods 17 to move closer to each other. The movement of the third sliding rods 17 brings the two sets of second mounting frames 33 connected to them closer to each other. The movement of the two sets of second mounting frames 33 brings the two second cover plates 34 out of the right-angled trapezoidal groove of the well seat 2, so that they cover the rectangular groove on the second opposite side of the inner layer of the well seat 2. This covers all the rectangular grooves on the well seat 2, preventing debris from entering the rectangular grooves and water channels of the well seat 2, thus reducing the waterproof effect.

[0106] Example 5

[0107] Based on the fourth specific implementation method, such as Figure 12-15 As shown,

[0108] It also includes support mechanisms, of which two are provided, and the support mechanisms include,

[0109] An embedded mounting box 20 is disposed in the concrete on the side of the well wall 1.

[0110] Guide plate 21, the guide plate 21 is installed in the concrete on the side of the well wall 1.

[0111] Two first electric telescopic rods 23 are provided, and the two first electric telescopic rods 23 are symmetrically arranged within the embedded mounting box 20.

[0112] A sliding mounting plate 24 is slidably disposed on the guide plate 21. The sliding mounting plate 24 is fixedly connected to the telescopic end of the first electric telescopic rod 23. The sliding mounting plate 24 has two mutually symmetrical sliding grooves.

[0113] A limiting support assembly is provided, which connects the well wall 1 and the well cover 3, and provides temporary support when the well cover 3 is tilted.

[0114] The limiting support component includes:

[0115] Support rod 25, two of which are symmetrically arranged, are rotatably mounted on the sliding mounting plate 24 via an electric rotating shaft. Each support rod 25 has rubber pads at both ends, and the end of the support rod 25 closest to the sliding mounting plate 24 is spherical.

[0116] Two locking posts 32 are provided, and the two locking posts 32 are respectively installed on the two support rods 25.

[0117] Support block 18, two support blocks 18 are provided, and the two support blocks 18 are symmetrically installed on the well base 2. The support block 18 has a semi-cylindrical groove.

[0118] The limiting support component also includes

[0119] Two sliding support seats 26 are provided, each slidably disposed in one of the two grooves of the sliding mounting plate 24. Each sliding support seat 26 has a spherical groove, and the spherical end of the support rod 25 slides in contact with the spherical groove of the sliding support seat 26.

[0120] Two baffles 27 are provided, and the two baffles 27 are symmetrically arranged on the sliding mounting plate 24.

[0121] Two lifting mounting cylinders 28 are provided, and the two lifting mounting cylinders 28 are symmetrically arranged on the sliding mounting plate 24.

[0122] Two elastic elements 29 are provided, and the two elastic elements 29 are respectively installed inside the two lifting mounting cylinders 28.

[0123] Two second electric telescopic rods 30 are provided, and the fixed ends of the two second electric telescopic rods 30 are respectively installed on the two elastic members 29.

[0124] Two lifting blocks 31 are provided, each capable of being lifted and lowered within one of the two lifting mounting cylinders 28. The two lifting blocks 31 are respectively installed at the telescopic ends of the two second electric telescopic rods 30. The opposing sides of the two lifting blocks 31 are arc-shaped.

[0125] Electric door 22, which can be lifted and installed on the embedded mounting box 20.

[0126] In its initial state, the support rod 25 is arranged at an angle so that one of its spherical ends is located in the spherical groove of the sliding support seat 26. The locking post 32 is installed in the lower middle part of the support rod 25, and when the support rod 25 is rotated to its limit position, the locking post 32 is between the lifting block 31 baffle 27.

[0127] In this embodiment, the concrete around the manhole cover 3 is prone to collapse after prolonged vehicle traffic and earthquakes. When the concrete collapses, the manhole seat 2 will tilt. If a person steps on the tilted manhole seat 2, they may sprain their ankle, and a car may fall into it. Therefore, a support and fixing device is needed. When the manhole seat 2 tilts, the electric door 22 opens, and the first electric telescopic rod 23 extends. The extension of the first electric telescopic rod 23 pushes the sliding mounting plate 24 to move towards the center of the manhole wall 1 on the guide plate 21. After the sliding mounting plate 24 is completely removed from the embedded mounting box 20, the support rod 25 rotates away from the sliding mounting plate 24. The rotation of the support rod 25 drives the locking pin 32 to move synchronously. At the same time, the spherical head end of the support rod 25 moves. This forces the sliding support seat 26 to slide in the groove of the sliding mounting plate 24. Since the spherical end of the support rod 25 is provided with a rubber pad, the sliding support seat 26 provides support for the support rod 25. During the movement of the locking post 32, it contacts the arc surface of the lifting block 31. After that, the movement of the locking post 32 will press down on the lifting block 31, thereby compressing the elastic element 29. When the locking post 32 passes the lifting block 31, the elastic element 29 recovers. At this time, the locking post 32 is between the baffle 27 and the lifting block 31, thereby ensuring the horizontal rotation of the support rod 25. At this time, the spherical end of the support rod 25 does not enter the semi-cylindrical groove of the support block 18. When a pedestrian steps on the manhole cover 3, the manhole cover 3 will not tilt, and the rubber pad will also cushion the fall of the manhole cover 3.

[0128] When maintenance personnel repair the concrete around the manhole cover 3, the second electric telescopic rod 30 retracts, and the lifting block 31 descends inside the lifting installation cylinder 28. Then, the electric rotating shaft controls the support rod 25 to rotate the locking pin 32 in the opposite direction, so that it can smoothly pass through the lifting block 31 to return to the initial state, thereby achieving temporary support for the entire manhole cover 3.

[0129] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
