Abstract

The present invention discloses a flood prevention and waterlogging prevention rainwater manhole cover that can be quickly opened based on the Internet of Things, including a lower housing, and an upper housing is rotatably and clamped above the lower housing. A plurality of connecting pieces are connected in a circular arrangement on the circumferential side of the upper housing. A baffle is hinged inside the connecting piece, and a plurality of the baffles are combined into a disc structure. Both sides of the baffle are arc structures. By adding a driving mechanism, the driving mechanism can drive the expansion between a plurality of baffles. At the same time, the gaps left during the expansion process will not cause pedestrians to fall into the sewer along the wellhead. Moreover, the manhole cover forms a vortex by rotating, which can enable pedestrians to know that there is a manhole cover here during the day, and thus can avoid it in advance. In the case of low visibility at night, night lighting is provided by a lighting lamp, thereby preventing pedestrians from falling into the sewer. And because the vortex formed by the manhole cover can accelerate the water flow rate, the subsequent drainage speed is improved.

Description

Technical Field

[0001] The present invention relates to the technical field of manhole covers, and specifically to a flood-control and waterlogging-preventing rainwater manhole cover that can be quickly opened based on the Internet of Things. Background Technique

[0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. Currently, the sewer design is imperfect. Whenever there is heavy rain, many places in the city face the tragedy of being flooded. At this time, the solution of the relevant departments is to manually remove the manhole cover when the rainstorm comes, so that the rainwater can directly drain into the sewer through the wellhead. However, this method is time-consuming and laborious and has very low efficiency. Secondly, this method is not safe. When pedestrians are walking in the rain, due to the heavy rain and the untimely drainage of the wellhead, the wellhead is directly submerged and covered by the flood. Pedestrians walking in the water, especially at night in this situation, it is very difficult to identify the location of the wellhead. Once stepping into the wellhead, under the huge impact of the flood, pedestrians are helpless and can only be washed away by the flood. Summary of the Invention

[0003] The purpose of the present invention is to provide a flood-control and waterlogging-preventing rainwater manhole cover that can be quickly opened based on the Internet of Things to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A flood-control and waterlogging-preventing rainwater manhole cover that can be quickly opened based on the Internet of Things, including a lower housing, an upper housing is rotatably and clamped above the lower housing. A plurality of connecting members are connected in a circular arrangement on the periphery of the upper housing. A baffle is hinged inside the connecting member. A plurality of the baffles are combined into a disc structure. Both sides of the baffle are arc structures. A connecting rod is rotatably connected to the inner wall of the upper housing. The lower end of the connecting rod is connected to a rod body. A driving mechanism is connected above the rod body. Both ends of the rod body are connected with sliders. Limiting grooves adapted to the sliders are opened on both sides of the inner wall of the lower housing.

[0006] Preferably, the driving mechanism includes an electric push rod connected to the central part above the rod body. A push block located at the central part of the through hole is connected above the electric push rod. The edge of the push block is closely attached to one side of the baffle. A plurality of gear teeth are connected in a circular arrangement on the periphery of the inner wall of the upper housing. A waterproof motor is connected to the edge above the rod body. The output end of the waterproof motor is connected with a gear that meshes with the gear teeth.

[0007] Preferably, one end of the connecting rod is connected with a ring body with a T-shaped cross-section. A first annular groove adapted to the ring body is connected to the periphery of the inner wall of the upper housing.

[0008] Preferably, a second annular groove is formed above the lower housing. A connecting cylinder is rotatably connected inside the second annular groove. A connecting block is connected above the connecting cylinder. A groove adapted to the connecting block is formed above the upper housing. The connecting block is clamped in the vertical direction of the groove.

[0009] Preferably, a sliding groove is formed above the groove. A rotating rod is rotatably connected inside the sliding groove. A threaded disc is connected to one end of the rotating rod. Positioning grooves communicating with the groove are formed on both sides of the sliding groove. A positioning rod threadedly engaged with the threaded disc is slidably engaged in the parallel direction of the positioning groove. Card slots adapted to the positioning rods are formed on both sides of the connecting block.

[0010] Preferably, a first flat thread is provided on one side of the threaded disc. A second flat thread threadedly engaged with the first flat thread is provided above the positioning rod.

[0011] Preferably, a straight groove is formed above the rotating rod. A sliding rod is slidably engaged in the parallel direction of the straight groove. One end of the sliding rod passing through the sliding groove is connected with a knob. A placement groove adapted to the knob is formed above the sliding groove.

[0012] Preferably, a pressing plate is connected above the pushing block. A pressing groove adapted to the pressing plate is formed above the baffle. A notch is formed above the pushing block. A lighting lamp is arranged inside the notch. A transparent plate is installed above the lighting lamp.

[0013] Preferably, the connecting member includes a connecting frame. A rotating block rotatably connected inside the connecting frame is connected to the second side of the baffle. Fixed rods are connected to both ends of the rotating block. Positioning holes adapted to the fixed rods are formed on both sides of the inner wall of the connecting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. By adding a driving mechanism, the driving mechanism can drive multiple baffles to unfold. At the same time, the gaps left during the unfolding process will not cause pedestrians to fall into the sewer along the wellhead. And the manhole cover forms a vortex by rotating, so that pedestrians can know that there is a manhole cover here during the day and can avoid it in advance. In the case of low visibility at night, night lighting is provided by the lighting lamp, thus preventing pedestrians from falling into the sewer. And since the vortex formed by the manhole cover can accelerate the water flow speed, the subsequent drainage speed is improved.

[0016] 2. The provision of the connecting cylinder facilitates the personnel to snap the upper housing. When it is necessary to maintain the sewer, the upper housing can be disassembled. At the same time, the driving mechanism connected to the upper housing will also slide out from the space of the lower housing, avoiding the inconvenience of sewer maintenance caused by the small opening of the subsequent baffle. Moreover, the snap connection method is simple, which facilitates the subsequent disassembly of the upper housing and the lower housing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0023] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] A flood-control and waterlogging-preventing rainwater manhole cover that can be quickly opened based on the Internet of Things, including a lower housing 1. An upper housing 2 is rotatably and clamped above the lower housing 1. The clamping method of the upper housing 2 and the lower housing 1 facilitates the opening of the manhole cover during the maintenance of the sewer, facilitating subsequent personnel to enter the sewer. A plurality of connecting pieces are connected in a circular arrangement on the periphery of the upper housing 2. A baffle 3 is hinged inside the connecting piece. The baffle 3 is an arc-shaped plate structure. A plurality of baffles 3 are combined into a disc structure. Both sides of the baffle 3 are arc structures. The setting of the arc structures avoids interference when the plurality of baffles 3 are unfolded. A through hole is left in the middle of the combined arc structure. The setting of the through hole facilitates the subsequent pushing of the baffle by the push block 9. A connecting rod 4 is rotatably connected to the inner wall of the upper housing 2. The lower end of the connecting rod 4 is connected to a rod body 5. The connecting rod 4 is provided to fix the rod body 5, and since the connecting rod 4 is rotatable, it does not affect the subsequent rotation of the upper housing 2. A driving mechanism is connected above the rod body 5. Sliders 6 are connected to both ends of the rod body 5. Limiting grooves 7 adapted to the sliders 6 are provided on both sides of the inner wall of the lower housing 1. The setting of the sliders 6 and the limiting grooves 7 prevents the subsequent rod body 5 from rotating together with the upper housing 2.

[0025] The driving mechanism includes an electric push rod 8 connected to the central part above the rod body 5. The electric push rod 8 is a waterproof electric push rod 8. Above the electric push rod 8 is connected a push block 9 located at the center of the through hole. The cross-section of the push block 9 is a trapezoidal block. The edge of the push block 9 is in close contact with one side of the baffle 3. A plurality of gear teeth are connected in a circular arrangement on the periphery of the inner wall of the upper housing 2. The setting of the gear teeth and the gear 11 allows the upper housing 2 to rotate at a high speed. Thus, a vortex can be formed at the upper housing 2, making the water flow into the sewer faster. A waterproof motor 10 is connected to the edge above the rod body 5. The setting of the waterproof motor 10 prevents the motor from being damaged due to long-term contact with water. The output end of the waterproof motor 10 is connected to a gear 11 that meshes with the gear teeth.

[0026] One end of the connecting rod 4 is connected to an annular body 12 with a T-shaped cross-section. A first annular groove 13 adapted to the annular body 12 is connected to the periphery of the inner wall of the upper housing 2. The setting of the first column and the first annular groove 13 prevents the subsequent connecting rod 4 from being suspended, improving the stability after the connecting rod 4 is installed.

[0027] Above the lower housing 1, a second annular groove 14 is provided. Inside the second annular groove 14, a connecting cylinder 15 is rotatably connected. Above the connecting cylinder 15, a connecting block 16 is connected. Above the upper housing 2, a groove 17 adapted to the connecting block 16 is provided. The connecting block 16 is clamped in the vertical direction of the groove 17. The arrangement of the connecting cylinder 15 facilitates the clamping of the upper housing 2 by the personnel. And the connecting block 16 is of a rectangular block structure, and the groove 17 is of a rectangular groove structure. Through the arrangement of the connecting block 16 and the groove 17, when the personnel combine the upper housing 2 and the lower housing 1 subsequently, the position is more accurate, which facilitates the combination of the upper housing and the lower housing 1 by the personnel.

[0028] Above the groove 17, a sliding groove 18 is provided. Inside the sliding groove 18, a rotating rod 19 is rotatably connected. One end of the rotating rod 19 is connected with a threaded disc 20. On both sides of the sliding groove 18, positioning grooves 21 communicating with the groove 17 are provided. In the parallel direction of the positioning grooves 21, a positioning rod 22 threadedly engaged with the threaded disc 20 is slidably fitted. The cross-section of the positioning rod 22 is of a U-shaped rod structure. On both sides of the connecting block 16, clamping grooves adapted to the positioning rod 22 are provided. Through the arrangement of the threaded disc 20, the relative movement between the two positioning rods 22 can be driven simultaneously, and then the connecting block 16 can be clamped, thereby improving the stability of the positioning rod 22 after installation.

[0029] On one side of the threaded disc 20, a first flat thread is provided. Above the positioning rod 22, a second flat thread threadedly engaged with the first flat thread is provided. Through the self-locking properties of the first flat thread and the second flat thread, the stability of the subsequent position adjustment of the positioning rod 22 can be improved.

[0030] Above the rotating rod 19, a straight groove 23 is provided. In the parallel direction of the straight groove 23, a sliding rod 24 is slidably fitted. One end of the sliding rod 24 passing through the sliding groove 18 is connected with a knob 25. Above the sliding groove 18, a placement groove 32 adapted to the knob 25 is provided. The straight groove 23 is of a rectangular groove structure, and the sliding rod 24 is of a rectangular rod structure. Through the arrangement of the straight groove 23 and the sliding rod 24, the rotating rod 19 can be driven to rotate in the sliding groove 18, and the arrangement of the sliding rod 24 is used to make the manhole cover more flat, avoiding the situation that personnel are tripped by the rotating rod 19.

[0031] Above the push block 9, a pressing plate 26 is connected. Above the baffle 3, a pressing groove adapted to the pressing plate 26 is provided. Above the push block 9, a notch 27 is provided. Inside the notch 27, a lighting lamp 28 is provided. Above the lighting lamp 28, a transparent plate 29 is installed. Through the arrangement of the lighting lamp 28, it can remind personnel that there is a manhole cover here at night, and can also remind personnel and vehicles that the manhole cover here has been opened when the water level is too high, avoiding personnel from falling into the manhole cover. The transparent plate 29 is made of PE material, and the transparent plate 29 seals the notch 27 by means of screws.

[0032] The connecting member includes a connecting frame 30. A rotating block 31 that rotates within the connecting frame 30 is connected to the second side of the baffle 3. Fixed rods are connected to both ends of the rotating block 31. Positioning holes adapted to the fixed rods are formed on both sides of the inner wall of the connecting frame 30. The connecting frame 30 positions the position of the rotating block 31, and the setting of the rotating block 31 enables the baffle 3 to be unfolded upward. The settings of the fixed rods and the positioning holes prevent the rotating block 31 from being suspended, improving the stability of the rotation of the rotating block 31.

[0033] Working principle: When flood discharge is required, first turn on the electric guide rail to make the push block 9 connected to the output end of the electric guide rail move upward. Subsequently, the push block 9 will push multiple baffles 3 to form an angular space between the multiple baffles 3. Then, the water flow will flow in from the angle. Subsequently, turn on the lighting lamp 28 to make the lighting lamp 28 emit light to remind pedestrians at night. Then, turn on the waterproof motor 10 to make the gear 11 connected to the output end of the waterproof motor 10 rotate. Then, the gear 11 drives the upper housing 2 to rotate through the cooperation with the internal teeth of the inner wall of the upper housing 2. At the same time, during the rotation of the upper housing 2, the first column body will rotate in the first annular groove 13, and the connecting cylinder 15 will rotate in the second annular groove 14. Then, due to the high-speed rotation of the upper housing 2, a vortex will be formed and the water will be attracted into the sewer, thus completing the flood discharge treatment of the manhole cover. When attracting and maintaining the sewer, first pull the knob 25 to make the slide rod 24 connected to the knob 25 slide out along the chute 18. Subsequently, rotate the knob 25 to make the knob 25 drive the rotating rod 19 to rotate through the slide rod 24. Then, the threaded disc 20 connected to the rotating rod 19 will rotate in the chute 18. Then, the threaded disc 20 will drive the relative movement between the two positioning rods 22. Then, the positioning rods 22 will slide out of the card slots formed in the connecting block 16. Then, the personnel pull the upper housing 2 to make the connecting block 16 slide out of the groove 17. At the same time, the sliders 6 at both ends of the rod body 5 will move upward along the inner wall of the lower housing 1. Then, the maintenance personnel can enter the sewer from the opening formed by the lower housing 1. When the baffle 3 needs to return to its original position, it is the same principle.

[0034] The electric push rod 8 and the waterproof motor 10 in the above-mentioned parts can both be controlled through the Internet of Things. The Internet of Things is a network that connects any item to the Internet through information sensing devices, exchanges and communicates information according to an agreed protocol, and realizes intelligent identification, positioning, tracking, monitoring, and management.
