Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, and in particular to a manhole cover structure with electromagnetic power generation function. Background Technology

[0002] For a long time, traditional manhole covers have primarily served the basic protective function of covering manhole openings and preventing people and objects from falling in. For example, in urban streets and residential roads, they have only served as simple road barrier devices. However, this single function is no longer sufficient to meet the growing urban energy demands and the trend of intelligent development.

[0003] While electromagnetic power generation technology has applications in other fields, directly applying it to manhole cover scenarios faces numerous challenges. The pressure direction, frequency, and intensity experienced by manhole covers are complex and variable, differing significantly from conventional power generation scenarios. Existing technologies struggle to adapt precisely, resulting in low power generation efficiency.

[0004] Integrating an electromagnetic power generation device into the existing structure of a manhole cover requires ensuring that the cover's original protective and drainage functions are not affected, while also guaranteeing the stable operation of the power generation device. This places extremely high demands on structural design and spatial layout. Previous attempts have resulted in a decline in the overall performance of the manhole cover due to unreasonable structural integration, such as a significant increase in the cover's weight affecting its opening flexibility, or the power generation device becoming susceptible to damage from external environmental interference. Therefore, those skilled in the art have provided a manhole cover structure with electromagnetic power generation functionality to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a manhole cover structure with electromagnetic power generation function. To achieve the above objective, this utility model provides the following technical solution: it includes a manhole base, with an electromagnetic power generation box installed at the bottom of the upper cover plate. When pedestrians or vehicles apply pressure to the manhole cover, the upper cover plate drives the active seat, transmission rod, and other transmission components to drive the first electromagnetic coil at the bottom of the movable electromagnetic plate to approach the second electromagnetic coil at the top of the electromagnetic generator. By utilizing the principle of electromagnetic induction, the pressure mechanical energy is converted into electrical energy to power urban facilities and realize energy recovery and utilization.

[0006] Preferably, several drainage holes are opened at the bottom of the manhole cover to quickly drain the water inside the manhole, avoid traffic hazards caused by water accumulation on the road, and at the same time reduce the corrosion of the manhole cover and surrounding road surface by water accumulation, thus extending the service life of the manhole cover and road surface.

[0007] Preferably, the first movable box on both sides of the bottom of the well plate is provided with a first movable groove, which cooperates with the second movable groove of the well plate. The transmission structure composed of the active seat, the transmission rod, and the driven seat accurately and stably transmits the pressure of the upper cover plate to the electromagnetic power generation component, ensuring the continuity of the power generation process.

[0008] Preferably, when the locking bolt is tightened or loosened, it may exert a certain impact force on the locking component. The locking groove and the second spring work together to buffer these impact forces, reduce damage to the locking component and the entire locking structure, extend its service life, and also ensure the stability and reliability of the bottom door when it is closed.

[0009] Preferably, when the locking bolt is screwed into the internal thread sleeve, the locking component will automatically adjust its position according to the outer diameter of the locking bolt and the screwing position under the action of the second spring, tightly fitting against the surface of the locking bolt, increasing the friction between the two, preventing the locking bolt from loosening due to external force vibration or other reasons, and playing a good fastening role.

[0010] Preferably, the locking element located on both sides of the middle of the inner wall of the locking block has one end connected to the second spring, and the other end passing through and movably connected to both sides of the inner wall of the internal threaded sleeve. The second spring provides elastic force to the locking element, causing it to tend to move inward (i.e., towards the center of the internal threaded sleeve) in its natural state, thereby clamping and positioning the locking bolt inserted into the internal threaded sleeve.

[0011] Ideally, continuous power generation can supply power to surrounding equipment, reduce municipal facilities' reliance on traditional energy sources, reduce carbon emissions, conform to green and environmentally friendly concepts, and contribute to the sustainable development of the city.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the pressure generated by pedestrians or vehicles stepping on or running over the top cover plate is used to drive the movable electromagnetic plate and the first electromagnetic coil to move through the coordinated operation of a series of components such as the active seat, transmission rod, and driven seat. This cuts the magnetic field generated by the second electromagnetic coil, thereby realizing electromagnetic induction power generation. This method of converting everyday mechanical energy into electrical energy provides a green and sustainable distributed power supplement for cities, which can power streetlights, nearby monitoring equipment, etc., effectively reducing urban energy consumption.

[0014] 2. In this utility model, the first movable groove in the first movable box, in conjunction with the second movable groove, provides precise guidance for the movement of components such as the active seat and transmission rod, ensuring stable and reliable pressure transmission. Simultaneously, the transmission groove limits the range of motion of the connecting rod, and in conjunction with the first spring, not only ensuring the stable lifting and lowering of the movable electromagnetic plate, but also buffering pressure, reducing component wear, and extending the overall service life of the manhole cover. Compared to some traditional manhole covers with simple structures and loose connections, its stability is significantly improved.

[0015] 3. In this utility model, a bottom door is provided at the bottom of the electromagnetic generator box, which is connected by a limit seat and fixed by a locking bolt and an internal threaded sleeve. When it is necessary to inspect the internal power generation components such as the electromagnetic generator, simply unscrew the locking bolt, and the locking parts on both sides will separate from the locking groove under the action of the second spring, and then the bottom door can be opened. The operation is simple and greatly saves maintenance time and cost. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 — Figure 4This is a manhole cover structure with electromagnetic power generation function. The structure consists of several key components, including a manhole base 1, a manhole plate 2, and a top cover 3. Construction workers first place the manhole base 1 firmly in the pre-dug manhole opening. The manhole base is made of high-strength cast iron, making it sturdy and durable, capable of withstanding the heavy pressure of passing vehicles. Next, the manhole plate 2 is installed on top of the manhole base 1. Several drainage holes 5, approximately 3 centimeters in diameter and circular in shape, are evenly distributed at the bottom of the manhole plate 2. These holes quickly drain water from the manhole, preventing water accumulation on the road surface from affecting pedestrian traffic and road safety.

[0023] Subsequently, the workers installed the top cover plate 3 at the center of the top of the well plate 2. The top cover plate and the well plate are connected by a specially designed hinge, ensuring that the top cover plate can be opened and closed flexibly, facilitating future maintenance of the facilities inside the well. At the bottom center of the top cover plate 3, the electromagnetic generator box 6 is installed. The electromagnetic generator box 6 uses waterproof and dustproof sealing materials to effectively protect the internal power generation components from the influence of the external environment.

[0024] A transmission groove 7 is provided in the middle of the two side walls of the electromagnetic generator box 6, which is an important channel for the power generation transmission structure. A first movable box 4 is installed on both sides of the bottom center of the well plate 2. A first movable groove 20 is provided on the inner side wall of the first movable box 4, and a second movable groove 21 is provided at the connection between the first movable groove 20 and the well plate 2. The active seat 19 on both sides of the bottom center of the upper cover plate 3 passes through the bottom of the corresponding second movable groove 21. A transmission rod 18 is installed at the bottom of the active seat 19, and the driven seat 17 at the bottom of the transmission rod 18 is movably connected to the inner side wall of the corresponding first movable groove 20. When a pedestrian or vehicle steps on the upper cover plate 3, the upper cover plate 3 rotates under force, causing the active seat 19 to move downwards, which in turn pushes the driven seat 17 to slide within the first movable groove 20 via the transmission rod 18.

[0025] The connecting rods 16 mounted on the bottom of the driven seat 17 are arranged in a mirror image, with their side walls penetrating and movably connected to the inner side walls of the corresponding transmission grooves 7. As the driven seat 17 moves, the connecting rods 16 also move. A first spring 14 is installed at the middle position of the bottom of the inner side wall of the transmission groove 7, with one end connected to the bottom of the connecting rod 16 and the other end fixed to the bottom of the transmission groove 7. When the connecting rod 16 moves downward, the first spring 14 is compressed, storing elastic potential energy. A movable electromagnetic plate 8 is installed at the bottom of the connecting rod 16, and a first electromagnetic coil 9 is installed at the middle position of the bottom of the movable electromagnetic plate 8.

[0026] An electromagnetic generator 10 is installed on the inner wall of the electromagnetic generator box 6, and the top of the electromagnetic generator 10 is electrically connected to the second electromagnetic coil 11. When the movable electromagnetic plate 8 approaches the second electromagnetic coil 11 under the action of the connecting rod 16, the first electromagnetic coil 9 and the second electromagnetic coil 11 interact. According to the principle of electromagnetic induction, the electromagnetic generator 10 generates current and realizes power generation.

[0027] To facilitate internal maintenance of the electromagnetic generator box 6, a limiting seat 13 is installed on one side of the bottom center of the electromagnetic generator box 6. The inner wall of the limiting seat 13 is rotatably connected to the bottom door 15. A locking bolt 22 is threadedly connected to the bottom of the bottom door 15 on the side away from the limiting seat 13. A locking block is installed below the transmission groove 7 and above the locking bolt 22. An internally threaded sleeve 23 is installed at the center of the bottom of the inner wall of the locking block. The locking bolt 22 and the internally threaded sleeve 23 are threadedly connected to ensure the sealing and safety of the bottom door when closed.

[0028] Working principle: When a pedestrian or vehicle applies pressure to the upper cover plate 3, the upper cover plate 3 rotates around the rotational connection point between it and the top of the well plate 2. At this time, the active seats 19 installed on both sides of the bottom center of the upper cover plate 3 move downwards. The active seats 19 pass through the bottom of the corresponding second movable groove 21, driving the transmission rod 18 connected to them to move downwards. The driven seat 17 at the bottom of the transmission rod 18 slides within the first movable groove 20 opened in the inner side wall of the first movable box 4, thereby ensuring the stability of the transmission.

[0029] When the driven seat 17 moves downward, the connecting rod 16 installed at its bottom also moves downward. The connecting rod 16 is distributed in a mirror image, with its two side walls penetrating and sliding along the inner side wall of the corresponding transmission groove 7. Since the transmission groove 7 is located in the middle of the two side walls of the electromagnetic generator box 6, the downward movement of the connecting rod 16 will drive the movable electromagnetic plate 8 installed at its bottom to move downward. The bottom two sides of the movable electromagnetic plate 8 are connected to the first spring 14, which is installed in the middle of the bottom of the inner side wall of the transmission groove 7. During the downward movement of the movable electromagnetic plate 8, the first spring 14 is compressed, storing elastic potential energy.

[0030] The first electromagnetic coil 9, installed at the bottom center of the movable electromagnetic plate 8, is then brought close to the second electromagnetic coil 11, which is electrically connected to the top of the electromagnetic generator 10 installed on the inner wall of the electromagnetic generator box 6. The first electromagnetic coil 9 and the second electromagnetic coil 11 are matched. When the first electromagnetic coil 9 is brought close to the second electromagnetic coil 11 by the movable electromagnetic plate 8, a current will be generated in the electromagnetic generator 10 according to the principle of electromagnetic induction, thus realizing the power generation function.

[0031] When the pressure disappears, the first spring 14 releases its elastic potential energy, pushing the movable electromagnetic plate 8, connecting rod 16 and other components to reset, and the first electromagnetic coil 9 moves away from the second electromagnetic coil 11, completing one power generation process.

[0032] In addition, a bottom door 15 is rotatably connected to a limiting seat 13 installed on one side of the bottom center of the electromagnetic generator box 6. The bottom side of the bottom door 15, away from the limiting seat 13, is threadedly connected to the internal threaded sleeve 23 on the locking block by a locking bolt 22, facilitating maintenance and other operations inside the electromagnetic generator box 6. Several drainage holes 5 opened at the bottom of the manhole cover 2 can effectively drain water accumulated in the manhole, ensuring the normal operation of the manhole cover structure and the surrounding environment.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
