[0002] A municipal well cover refers to a well cover used on municipal infrastructure such as urban roads, sidewalks, and public areas. Currently, well covers mainly have the functions of anti-theft warning, ventilation, and drainage when in use. Traditional well covers are generally directly placed above the wellhead, which has led to many theft incidents. Therefore, in order to prevent such incidents from occurring, some fixing components are generally added to make the well cover better embedded above the wellhead, and a warning device is added inside the well cover to improve its safety. However, at the same time, when heavy rain occurs or floods break out, the drainage well cover is blocked due to the sediment and garbage mixed in the water, resulting in blockage of the drainage outlet on the well cover, and it often requires workers to open the well cover to drain the accumulated water.

[0042] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present utility model, but do not limit the scope of the present utility model. Similarly, the following embodiments are only partial embodiments of the present utility model rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0043] Please refer to Figures 1 to 5 , this embodiment provides a multi-functional manhole cover for mud-water separation, which includes a cover body 1, a cylindrical shell 2, a deflector group 3, a fan blade group, and a collection tank 5. A plurality of grilles are provided on the cover body 1; the cylindrical shell 2 includes a first opening and a second opening. The cover body 1 is provided on the first opening, and the second opening is disposed opposite to the first opening; the deflector group 3 is disposed inside the cylindrical shell 2. The deflector group 3 includes a first deflector 31, a second deflector 32, and a first deflector groove 33. The first deflector 31 and the second deflector 32 are symmetrically distributed along the central axis of the cylindrical shell 2. The radial distance between the first deflector 31 and the second deflector 32 gradually decreases from the first opening towards the second opening according to a preset gradient to the area where the first deflector groove 33 is located. The first deflector 31 and the second deflector 32 are used to divert water to the first deflector groove 33; the fan blade group is disposed inside the cylindrical shell 2. The fan blade group can rotate relative to the cylindrical shell 2, and the fan blade group is disposed below the first deflector groove 33. The fan blade group includes a plurality of fan blades 4, and the fan blades 4 are used to transport the sediment in the water to the edge of the cylindrical shell 2; the collection tank 5 is disposed at the second opening. A sediment diversion port 21 is provided on the side wall of the cylindrical shell 2. The collection tank 5 is communicated with the sediment diversion port 21, and the collection tank 5 is used to collect sediment.

[0044] In this embodiment, the cover body 1 can be understood as a normal manhole cover structure. A plurality of grilles are provided on the cover body 1, and the size of the grilles can be adjusted according to actual needs to effectively block large garbage and sundries. In this embodiment, the cylindrical shell 2 is a cylindrical shell structure. For the convenience of description, the two ends of the cylindrical shell 2 are denoted as the first opening and the second opening. In the normal use state, the cylindrical shell 2 is placed vertically, the first opening is upward, and the second opening is downward. The cover body 1 is provided at the first opening. That is, during the use of the multi-functional manhole cover shown in this embodiment, the cylindrical body needs to be placed in the corridor connecting the sewer and the road surface, the cover body 1 is adjusted to the same height as the road surface, and the lower part of the second opening is also the main passage of the sewer. The water flows into the cylindrical shell 2 through the grilles on the cover body 1 and finally flows into the sewer.

[0045] Please refer to Figures 2 to 5, Further, in this embodiment, a deflector plate group 3 is provided. The deflector plate group 3 includes a first deflector plate 31, a second deflector plate 32, and a first deflector groove 33. The first deflector groove 33 is a through groove structure formed under the arrangement of the first deflector plate 31 and the second deflector plate 32. Specifically, the first deflector groove 33 and the second deflector groove are symmetrically distributed along the central axis of the cylindrical shell 2. The radial distance between the first deflector plate 31 and the second deflector plate 32 can be understood as the straight-line distance between the first deflector plate 31 and the second deflector plate 32 along the radial direction of the cylindrical shell 2. Regarding the radial distance between the first deflector plate 31 and the second deflector plate 32 gradually decreasing to the area where the first deflector groove 33 is located according to a preset gradient from the first opening towards the second opening, it can be understood as follows: In the normal use state of the cylindrical shell 2, when the cylindrical shell 2 is in a vertical manner, the radial distance between the first deflector plate 31 and the second deflector plate 32 gradually decreases from top to bottom until the first deflector groove 33 is formed. That is, the first deflector plate 31 and the second deflector plate 32 form a V-shaped deflector structure, and the open end of the V-shaped deflector structure faces the direction where the cover body 1 is located. The first deflector groove 33 is arranged at the intersection of the V-shaped deflector structure. Then, after the water seeps into the grille of the cover body 1, it will be gathered into the first deflector groove 33 under the drive of the first deflector plate 31 and the second deflector plate 32.

[0046] The fan blade group is arranged below the first deflector groove 33. The fan blade group can use the existing fan blade 4 structure or can be manufactured separately. In this embodiment, the number of fan blades 4 in the fan blade group is not limited. When the water volume in the first deflector groove 33 increases, the guidance of the first deflector plate 31 and the second deflector plate 32 will cause the water to generate the Bernoulli effect. That is, when the fluid velocity increases, the pressure decreases. When the available cross-sectional area becomes smaller, the fluid velocity increases and the pressure decreases. As a result, the water flow impacts the outer surface of the fan blade 4 at a relatively fast speed. Based on the principle of conservation of momentum, the kinetic energy contained in the water flow will be transferred to the fan blade 4, causing the fan blade 4 to rotate.

[0047] In this embodiment, when the fan blade 4 rotates, a centrifugal force will be generated. The continuous impact of the water flow causes the centrifugal force generated by the rotation of the fan blade 4 to act on the subsequent incoming water flow synchronously. According to Newton's second law, an object will generate an acceleration under the action of a force. The magnitude of the acceleration is proportional to the acting force and inversely proportional to the mass of the object. The centrifugal force can be regarded as the force generated by the centripetal acceleration received by the object. According to Newton's second law, the magnitude of the centrifugal force is equal to the mass of the object multiplied by the centripetal acceleration. Therefore, the greater the mass, the greater the centrifugal force. Under this principle, since the water flow contains sediment and the mass of the sediment is greater than that of the water, the centrifugal force received by the sediment is greater than that of the water. The sediment is thrown to the inner sidewall and the edge of the cylindrical shell 2 under the drive of the fan blade 4, realizing the separation operation of water and sediment. Specifically, Figure 2 The arrows in [diagram] represent the flow direction of the water flow, Figure 4 The arrows in [diagram] represent the flow direction of the sediment.

[0048] A sediment diversion opening 21 is provided on the inner side wall of the cylindrical shell 2. After the sediment is thrown out by the fan blades 4, it gets out of the influence of the centrifugal force and sinks under the action of its own weight, gathering at the edge of the inner side wall of the cylindrical shell 2. Driven by the remaining water flow, the sediment will flow into the sediment diversion opening 21 along the trend and thus enter the collection tank 5 connected to the sediment diversion opening 21, completing the collection of the sediment.

[0049] When this embodiment is in use, in the state of less water volume, the water flows into the deflector group 3 through the grille on the cover body 1, enters the first diversion groove 33 and falls. At this time, the water volume is small and cannot provide power for the fan blade group, and the current manhole cover functions as a normal manhole cover; in the state of more water volume, the large garbage or sundries mixed in will be blocked outside at the grille, and the water flow and fine sediment will flow into the deflector group 3 through the grille together. A large amount of water gathers at the first diversion groove 33 and falls onto the fan blades 4 of the fan blade group. The fan blades 4 start to rotate under the driving force of the water flow, and the sediment is brought to the edge of the cylindrical shell 2 by using the difference in centrifugal force. The sediment flows from the inner side wall of the cylindrical shell 2 into the collection tank 5 in the sediment diversion opening 21 under the mixing of the remaining small amount of water, completing the separation of the sediment and the water. The separation of the muddy water is realized by using the difference in centrifugal force, which can solve the problem that a large amount of muddy water blocks the holes of the manhole cover, timely guide the water to the sewer, and collect the excess sediment, improving the adaptability of the manhole cover to various environments. Moreover, using the water flow as the driving force of the fan blades 4 makes full use of the kinetic energy contained in the water flow, saves energy, has environmental protection advantages, and at the same time, there is no need to be equipped with a separate driving device, which avoids the problem of damage and maintenance of the driving device, reduces the manufacturing cost and prolongs the service life of the manhole cover.

[0050] Please refer to Figure 2 and Figure 3 , in some embodiments, it further includes a support beam 6, a support shaft 7 and a bearing 71. The support beam 6 is arranged inside the cylindrical shell 2 and below the fan blade group; the support shaft 7 is arranged at the center point of the support beam 6; the bearing 71 is sleeved outside the support shaft 7, and the fan blade group is sleeved on the bearing 71, and the fan blade group can rotate relative to the support shaft 7.

[0051] In this embodiment, the support beam 6 is arranged radially in the cylindrical shell 2 and is located below the fan blade group. A support shaft 7 is vertically provided on the support beam 6. Optionally, the diameter of the support shaft 7 is the same as that of the support beam 6 to ensure the support strength for the fan blade group. A bearing 71 is sleeved on the support shaft 7, and the fan blade group is sleeved outside the bearing 71. Specifically, the fan blade group may include a support ring, and a plurality of fan blades 4 are distributed circumferentially on the support ring. The support ring is sleeved on the bearing 71. Optionally, a shield or cover plate may be provided at the connection between the bearing 71 and the support ring to ensure the flexibility of use of the bearing 71 and reduce the probability of the bearing 71 being infiltrated and jammed by sediment. Or, the probability of sediment infiltration may also be reduced by selecting a suitable type of bearing 71, which can be specifically set according to actual needs.

[0052] Please refer to Figure 3 and Figure 5 , in some embodiments, it further includes a seepage plate 8. The seepage plate 8 is arranged in the cylindrical shell 2 and is located at the second opening. The seepage plate 8 is arranged at the lower edge of the sediment diversion opening 21, and a plurality of seepage holes 81 are provided on the seepage plate 8. In this embodiment, the seepage plate 8 is a disc structure with a size slightly smaller than the inner side wall of the cylindrical shell 2. A plurality of seepage holes 81 are provided on the seepage plate 8, and the size and distribution density of the seepage holes 81 can be set according to actual needs. The seepage plate 8 is arranged at the second opening, so that the seepage plate 8, the cover body 1 and the cylindrical shell 2 form a complete whole, strengthening the stability of the entire manhole cover structure.

[0053] Please refer to Figure 4 and Figure 5 , in some embodiments, the number of sediment diversion openings 21 is two, and they are oppositely arranged on the side wall of the cylindrical shell 2; the number of collection grooves 5 is two, and each collection groove 5 communicates with one sediment diversion opening 21.

[0054] In this embodiment, the number of sediment diversion openings 21 is two, and the two sediment diversion openings 21 are oppositely arranged on the side wall of the cylindrical shell 2. The number of collection grooves 5 corresponds one-to-one to the number of sediment diversion openings 21, and one collection groove 5 corresponds to one sediment diversion opening 21.

[0055] Optionally, in some embodiments, the number of sediment diversion openings 21 is multiple, and the multiple sediment diversion openings 21 are arranged circumferentially along the inner side wall of the cylindrical shell 2 to improve the efficiency of sediment collection.

[0056] In some embodiments, a first long groove and a second long groove are oppositely arranged at the sediment diversion opening 21; a first side edge and a second side edge are oppositely arranged on the collection groove 5, and the first side edge is fitted in the first long groove, and the second side edge is fitted in the second long groove.

[0057] In this embodiment, a first long groove and a second long groove are provided at the sediment diversion opening 21 and are oppositely arranged. Specifically, the first long groove and the second long groove are arranged in parallel, and the openings of the first long groove and the second long groove are both communicated with the second opening; a first side edge and a second side edge are provided at the edge of the collection groove 5. The first side edge and the second side edge can be understood as flange structures. When assembling the multi-functional manhole cover, the first side edge and the second side edge can be respectively aligned with the openings of the first long groove and the second long groove, and the collection groove 5 can be moved in from the second opening so that the first side edge is fitted into the first long groove and the second side edge is fitted into the second long groove. This method can realize the detachable connection between the collection groove 5 and the sediment diversion opening 21, facilitating the timely cleaning and removal of the sediment in the collection groove 5.

[0058] Please refer to Figure 1 , further, in some embodiments, a dumping opening 51 is provided at the top of the collection groove 5. The dumping opening 51 does not overlap with the sediment diversion opening 21. The dumping opening 51 can be arranged above the collection groove 5 to prevent sediment from directly leaking out of the collection groove 5 when it is not dumped.

[0059] Optionally, a partition board made of a water-permeable material can also be provided at the bottom of the collection groove 5 to facilitate the derivation of the residual water volume in the sediment to the outside, avoiding the backflow or leakage of the sediment caused by the accumulation of the water volume.

[0060] In some embodiments, the guide vane group 3 further includes a third guide vane. The third guide vane is arranged at the central axis of the cylindrical shell 2. The third guide vane has a guiding surface, and the guiding surface is conical. The guiding surface is used to guide the water to both sides of the first guide groove 33.

[0061] In this embodiment, the third guide vane can be understood as a conical structure. The third guide vane is arranged at the central axis of the cylindrical shell 2 and is arranged in the central area of the first guide groove 33. This method can ensure that the water flow guided by the first guide vane 31 and the second guide vane 32 does not concentrate in the central area but dispersedly falls into the two end areas of the first guide groove 33. That is, it reduces the flow rate of the water flow directly acting on the central area of the fan blade group and more water flow acts on the fan blades 4 to improve the driving efficiency of the fan blades 4.

[0062] In some embodiments, a first arc-shaped guide groove is provided on the fan blade 4. The first arc-shaped guide groove spirally extends from the central axis of the cylindrical shell 2 to the edge of the cylindrical shell 2. In this embodiment, the setting of the first arc-shaped guide groove can improve the efficiency of converting the kinetic energy contained in the water flow into the kinetic energy for driving the fan blade 4, and the first arc-shaped guide groove is convenient for more efficiently guiding the sediment onto the inner side wall of the cylindrical shell 2.

[0063] In some embodiments, a plurality of second arc-shaped guide grooves are provided on the inner side wall of the cylinder shell 2. The orientation of the second arc-shaped guide grooves is the same as that of the first arc-shaped guide grooves. The second arc-shaped guide grooves are used to divert the sediment to the inner edge of the cylinder shell 2; a collecting groove is provided at the edge of the seepage plate 8, and the collecting groove is communicated with the sediment diversion opening. It should be noted that the second arc-shaped guide grooves extend spirally from the first opening to the second opening, and the orientation of the second arc-shaped guide grooves is the same as that of the first arc-shaped guide grooves. This way can make the sediment be introduced into the edge of the cylinder shell 2 more efficiently.

[0064] Furthermore, a collecting groove is provided at the edge of the seepage plate 8. The depth of the groove body of the collecting groove can be inclined towards the sediment diversion opening 21, so that after the sediment enters the collecting groove, it is introduced into the sediment diversion opening 21 under the action of gravity, reducing the accumulation amount of sediment in the collecting groove.

[0065] Please refer to Figure 1 and Figure 2 , in some embodiments, the grille includes a first main grille 11, a plurality of first sub-grilles 12 and a plurality of second sub-grilles 13. The first main grille 11 is arranged at the central axis of the cover body 1. The plurality of first sub-grilles 12 are sequentially and spaced apart along one side of the first main grille 11, and the plurality of second sub-grilles 13 are sequentially and spaced apart along the other side of the first main grille 11.

[0066] In this embodiment, the first main grille 11, the first sub-grilles 12 and the second sub-grilles 13 are all arranged in parallel. It can be understood that the grille lengths of the plurality of first sub-grilles 12 are different, and the grille lengths of the plurality of second sub-grilles 13 are different, specifically as Figure 1 shown. This way can distribute more grilles on the limited cover body 1, expand the water flow introduction area, and improve the water flow introduction efficiency.

[0067] The multi-functional manhole cover for mud-water separation includes a cover body 1, a cylinder shell 2, a deflector plate group 3, a fan blade group, and a collection tank 5. The cover body 1 is provided with a plurality of grilles; the cylinder shell 2 includes a first opening and a second opening. The cover body 1 is provided on the first opening, and the second opening is disposed opposite to the first opening; the deflector plate group 3 is arranged inside the cylinder shell 2. The deflector plate group 3 includes a first deflector plate 31, a second deflector plate 32, and a first deflector groove 33. The first deflector plate 31 and the second deflector plate 32 are symmetrically distributed along the central axis of the cylinder shell 2. The radial distance between the first deflector plate 31 and the second deflector plate 32 gradually decreases from the first opening towards the second opening according to a preset gradient to the area where the first deflector groove 33 is located. The first deflector plate 31 and the second deflector plate 32 are used to divert water to the first deflector groove 33; the fan blade group is arranged inside the cylinder shell 2. The fan blade group can rotate relative to the cylinder shell 2, and the fan blade group is arranged below the first deflector groove 33. The fan blade group includes a plurality of fan blades 4, and the fan blades 4 are used to transport the sediment in the water to the edge of the cylinder shell 2; the collection tank 5 is arranged at the second opening. A sediment diversion port 21 is provided on the side wall of the cylinder shell 2. The collection tank 5 is communicated with the sediment diversion port 21, and the collection tank 5 is used to collect sediment. When in use, when the water volume is small, the water flows into the deflector plate group 3 through the grilles on the cover body 1, enters the first deflector groove 33 and falls. At this time, the water volume is small and cannot provide power to the fan blade group. The current manhole cover functions as a normal manhole cover; when the water volume is large, the large garbage or sundries mixed in will be blocked outside at the grilles. The water flow and the fine sediment flow into the deflector plate group 3 through the grilles together. A large amount of water gathers at the first deflector groove 33 and falls onto the fan blades 4 of the fan blade group. The fan blades 4 start to rotate under the driving force of the water flow, and use the difference in centrifugal force to bring the sediment to the edge of the cylinder shell 2. The sediment flows from the inner wall of the cylinder shell 2 into the collection tank 5 in the sediment diversion port 21 under the mixing of the remaining small amount of water, completing the separation of sediment and water. This technical solution realizes the separation of mud and water by using the difference in centrifugal force, can solve the problem that a large amount of mud and water blocks the holes of the manhole cover, timely guides the water to the sewer, collects the excess sediment, prolongs the service life of the manhole cover, and improves the adaptability of the manhole cover to various environments.

[0068] The above are only some embodiments of the present invention, and thus do not limit the protection scope of the present invention.
