Description

Technical Field

[0001] The present invention relates to the technical field of drainage treatment, and particularly to an automatic cleaning device for intercepting objects at a rainwater inlet. Background Art

[0002] Generally speaking, in the field of rainwater collection and treatment, the operation of urban rainwater treatment in various countries mainly reduces the peak flood and waterlogging by transporting runoff rainwater through drainage pipe networks. Among them, by arranging rain grates to block some floating objects on the ground from mixing into the pipe network, the pipe blockage can be reduced, and the pressure on the sewage treatment plant to receive sewage can be alleviated. However, the sizes of surface debris are various, and it is difficult to isolate them with a single rain grate. In the application of rain grates, if the gap between the rain grate bars increases, the drainage capacity improves, but at the same time, the number of floating scum entering the pipe increases, and the degree of siltation increases, resulting in a decline in the drainage capacity of the pipe network system and even the paralysis of the drainage system; if the gap between the rain grate bars decreases, the floating scum interception capacity improves, and the number of floating scum entering the pipe decreases, but the degree of floating scum blocking the grille increases, resulting in a reduction in the flow of rainwater into the pipe network, causing the discharge of runoff rainwater to be blocked, and further causing waterlogging.

[0003] Therefore, there is a need in the art for a new automatic cleaning device for intercepting objects at a rainwater inlet, which can eliminate or at least alleviate all or part of the defects in the above-mentioned prior art. Summary of the Invention

[0004] In view of the above technical problems existing in the prior art, the purpose of the present invention is to provide an automatic cleaning device for intercepting objects at a rainwater inlet, which can be hidden under the rain grate when there is no rain without disturbing ground traffic. During rainfall, the floating objects covering the rain grate are automatically shifted and removed by the strips of a rotating dial, and the intercepted floating scum or intercepted objects are temporarily collected in a storage bin, so that the runoff rainwater quickly flows into the catch basin through the rain grate with small gaps, and then is quickly drained away through the pipe network. Finally, the floating scum in the storage bin is removed after the rain stops.

[0005] To this end, according to an embodiment of the present invention, there is provided an automatic cleaning device for intercepting objects at a rainwater inlet, wherein the automatic cleaning device includes:

[0053] Refer to Figures 1 to 3 , schematically showing an automatic cleaning device for rainwater inlet interceptors according to an embodiment of the present invention, wherein the automatic cleaning device includes:

[0054] A rain grate 2, which is installed at the rainwater inlet of a catch basin 3 for rainwater collection, including a horizontal grille 201 embedded in the rainwater inlet in a manner parallel to the ground. The horizontal grille 201 is used to introduce rainwater into the catch basin 3 and filter out the solid waste carried in the rainwater, thereby intercepting the interceptors;

[0055] A storage bin 9, which is communicated with the rain grate 2 and is used to receive the interceptors intercepted by the rain grate 2;

[0057] The rotatable dial wheel 1 includes a central shaft portion rotatably mounted at the first end of the swing arm assembly and a dial bar 104 radially extending outward from the central shaft portion.

[0058] The driving water wheel 7 is mounted at the second end of the swing arm assembly opposite to the first end and is connected to the central shaft portion of the dial wheel 1 to rotate the dial wheel 1.

[0059] Wherein, when there is no rain, the driving water wheel 7 is in the first upward position and is located below the horizontal grille 201, and the dial wheel 1 is in the second downward position.

Further, in one embodiment, the swing arm portion may include two identical swing arms 5 arranged in parallel and spaced apart, and the rotating shaft 6 may vertically pass through the two swing arms 5. For example, the two swing arms 5 can be hinged to the shaft seat on the side wall of the catch basin 3 through the rotating shaft 6.

[0062] In the present invention, the swing arm assembly can act as the frame part for adjusting the posture of the actuator of the above automatic cleaning device; the rotating shaft 6 can act as the support and swing center of the above automatic cleaning device.

[0063] Generally speaking, as used herein, "effective torque" refers to the torque of rotational force applied to a rod or shaft that can drive a mechanical system to rotate or turn. Referring to Figure 1 , in one embodiment, when there is no rain, the driving water wheel 7 is in a state without rain injection, and the effective torque of the dial wheel 1 on the rotating shaft 6 is greater than the effective torque of the driving water wheel 7 on the rotating shaft 6; when it rains, the driving water wheel 7 is in a state with rain injection, and the effective torque of the driving water wheel 7 on the rotating shaft 6 is greater than the effective torque of the dial wheel 1 on the rotating shaft 6, so that the driving water wheel 7 descends from the first upward position to the first downward position, and the dial wheel 1 correspondingly tilts up from the second downward position to the second upward position.

[0064] In one embodiment, as Figure 3 shown, the central shaft portion may include:

[0065] A shifting wheel shaft 102, which may penetrate and be fixed to two swing arms 5;

[0066] A hub 103, which may be rotatably and concentrically sleeved outside the shifting wheel shaft 102 between two swing arms 5;

[0067] A transmission wheel 101, which may be rotatably mounted to the shifting wheel shaft 102 at the mutually facing sides of two swing arms 5;

[0068] Wherein, multiple rows of shifting bars 104 may be fixed to the outer surface of the hub 103, and the number of shifting bars 104 in each row is at least one.

[0069] As Figure 3 shown, the shifting bar 104 may be, for example, in the shape of a rod or a bar. In Figure 1 the shown example, five rows of shifting bars 104 may be fixed to the outer surface of the hub 103, and the number of shifting bars 104 in each row is five. The above is only an example, and the present invention is not limited thereto.

[0070] In one embodiment, the driving water wheel 7 may include:

[0071] A water wheel shaft 702, which may penetrate and be fixed to two swing arms 5;

[0072] A water bucket device 703, which may be rotatably and concentrically sleeved outside the water wheel shaft 702 between two swing arms 5;

[0073] A driving wheel 701, which may be rotatably mounted to the water wheel shaft 702 at the mutually facing sides of two swing arms 5,

[0074] Wherein, the water bucket device 703 may include a plurality of trough-shaped water buckets for receiving rainwater that are evenly distributed at intervals along the circumference, and a water leakage hole 704 may be opened near the bottom of each water bucket. After rainfall, the runoff rainwater terminates, and the rainwater remaining in the water bucket may flow out through the water leakage hole 704.

[0075] As Figure 3 shown, the trough-shaped water bucket may be, for example, a groove approximately in the shape of a trapezoid, relatively wide at the top and relatively narrow at the bottom of the groove, which is easy to collect rainwater. The water leakage hole 704 may be a round hole. The above is only an example, and the present invention is not limited thereto.

[0076] In one embodiment, the driving wheel 701 of the driving water wheel 7 and the transmission wheel 101 of the shifting wheel 1 may be connected by a transmission belt 4.

[0077] In one embodiment, both the driving wheel 101 and the driven wheel 701 can be gears, and the transmission belt 4 can correspondingly be a toothed transmission belt, a chain transmission belt, or the like. In another embodiment, both the driving wheel 101 and the driven wheel 701 can be pulley wheels, and the transmission belt 4 can correspondingly be a V-shaped conveyor belt, a flat belt, or the like. The above are only examples, and the present invention is not limited thereto.

[0078] In one embodiment, the rain grate 2 can include:

[0079] A horizontal grille 201, which can have at least one horizontally extending first grid and can be installed corresponding to the position of the bar 104, such that when the dial wheel 1 is in the second upwardly tilted position, the bar 104 can freely rotate within the first grid and extend above the horizontal grille 201;

[0080] A slag inlet 202, which can be located between the horizontal grille 201 and the storage bin 9, such that the intercepted objects enter the storage bin 9 through the slag inlet 202;

[0081] A vertical grille 203, which can be located above the slag inlet 202, and the two vertical sides of the vertical grille 203 can extend vertically downward to the third end adjacent to the storage bin 9 of the horizontal grille 201;

[0082] An inclined grille 206, which can extend obliquely downward from the third end of the horizontal grille 201 in a direction away from the horizontal grille 201;

[0083] A water filtering grate 205, which can extend horizontally from the fourth end of the inclined grille 206 away from the horizontal grille 201 in a direction away from the inclined grille 206 to the catch basin 3, and can include a plurality of gaps. For example, the above gaps can be round holes or oblong holes, etc.

[0084] In the present invention, the inclined grille 206 can function to guide the floating scum into the storage bin 9, and the vertical grille 203 can prevent the floating scum that has entered the storage bin 9 from exiting the storage bin 9. Further, the inclined grille 206 and the water filtering grate 205 are arranged in a multi-gap shape, such that the rainwater that has entered the storage bin 9 can flow into the catch basin 3.

[0085] In one embodiment, the storage bin 9 can be surrounded by the vertical grille 203, the inclined grille 206, the water filtering grate 205, and the side wall of the catch basin 3, and a cover plate 204 that can be opened is further provided at the top of the storage bin 9. The cover plate 204 can play a safety protection role and can also facilitate the removal of the floating scum after rainfall.

[0086] In the present invention, the storage bin 9 can function as a temporary storage space for the floating scum or intercepted objects in the runoff rainwater, for reducing the downstream diffusion of the floating scum. After rainfall or when the storage bin 9 is filled with intercepted objects, the cover plate 204 can be opened to remove the intercepted objects, which is convenient for cleaning.

[0087] In one embodiment, the driving water wheel 7 may further include a water guide plate 8 that extends obliquely downward from the first end of the horizontal grille 201 toward the bucket device 703. The water guide plate 8 does not contact the driving water wheel 7 and is used to divert the water flow away from the bucket device 703.

[0088] In the present invention, the water guide plate 8 is a power source adjustment part of the automatic cleaning device. During rainfall, the water guide plate 8 can divert the rainwater away from the buckets to reduce the reverse force or reverse torque of the driving water wheel 7.

[0089] The working process of the automatic cleaning device for rainwater inlet interceptors according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0090] When there is no rain, the effective torque of the dial wheel 1 on the rotating shaft 6 is greater than the effective torque of the driving water wheel 7 on the rotating shaft 6, so that the dial wheel 1 descends relative to the rotating shaft 6 and is located at the second descending position. At the same time, the driving water wheel 7 can correspondingly tilt up to the first tilting-up position and is located below the horizontal grille 201 to keep the ground flat and clean. During the rainfall runoff process, a part of the rainwater flow filtered by the rain grate 2 can flow into or be injected into the driving water wheel 7. For example, it flows into the bucket device 703 of the driving water wheel 7. As Figure 3 shown, due to the gravity of the injected rainwater, the effective torque of the driving water wheel 7 on the rotating shaft 6 is greater than the effective torque of the dial wheel 1 on the rotating shaft 6, so that the driving water wheel 7 can sink or descend to the first descending position. At the same time, the dial wheel 1 can correspondingly tilt up from the second descending position to the second tilting-up position. At the second tilting-up position, the dial bar 104 can rotate and extend above the horizontal grille 201. During the continuous rotation of the dial wheel 1, the dial bar 104 continuously clears the scum covering the horizontal grille 201. Subsequently, these scum or interceptors enter the storage bin 9 under the action of gravity and water flow impact. After the rainfall, the runoff rainwater terminates, and the rainwater remaining in the bucket 703 can flow out through the water leakage holes 704. After the water is drained, the driving water wheel 7 tilts up again, the dial wheel 1 sinks correspondingly, and the dial bar 104 is completely hidden below the horizontal grille 201. Then, the cover plate 204 of the storage bin 9 can be opened, and the scum or interceptors collected in the storage bin 9 are transported to the scum treatment site according to environmental protection requirements.

[0091] In summary, the automatic cleaning device for rainwater inlet interceptors according to the embodiment of the present invention can automatically remove the scum or interceptors intercepted by the rain grate in the rainwater, automatically collect the scum or interceptors, has a good cleaning effect, is hydraulically driven by rainwater without other external power, has a simple structure, is reliable in use, has a low cost, is easy to implement, and is conducive to the generalization of products, etc.

Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including said element.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
