Description

Technical Field

[0001] The utility model relates to the field of manhole covers, in particular to a rainwater manhole cover with automatic flood discharge. Background Art

[0002] Rainwater manhole covers have a flood discharge function during rainy days, allowing rainwater to flow down through the seepage holes of the manhole covers. However, for safety reasons, the seepage holes of such manhole covers are currently small. In heavy rain, it is easy for them to fail to drain water in time and cause waterlogging. Currently, there are solutions for flood control manhole covers, such as the flood control manhole cover disclosed in patent document No. CN104975646A. This solution uses a hollow manhole cover to float up and automatically open the manhole cover to drain floodwater. Although this solution can indeed prevent floods, the floating manhole cover also directly makes the area impassable for pedestrians and vehicles. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a rainwater manhole cover with automatic flood discharge, which can automatically open the drainage channel when the rain is too heavy and automatically close the drainage channel when the rain becomes less. It will not affect pedestrians and vehicles, is safer and more reliable, and saves manpower.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a rainwater manhole cover with automatic flood discharge, comprising an outer ring; a retaining net layer and a flood discharge layer are arranged inside the outer ring; the retaining net layer is located above the flood discharge layer; the outer edge of the retaining net layer is detachably adapted to the outer ring;

[0005] The flood discharge layer includes two semicircular plates, and a rotating shaft is provided on the diameter edge of the semicircular plate. The rotating shaft is rotatably matched with the outer ring. A balancing piece is provided on the lower part of the semicircular plate extending toward the lower part of the other semicircular plate. The balancing piece drives the outer edge of the semicircular plate to tilt and engage with the outer ring. The semicircular plate is provided with a locking pin, and the inner wall of the outer ring is provided with a lock hole corresponding to the locking pin.

[0006] Since the semicircular plate is tilted up by the balancing part and then cooperates with the outer ring, when the outer edge of the semicircular plate is subjected to downward pressure, it will swing downward, thereby opening a channel for rainwater to flow downward. The heavier the rain, the greater the amplitude of the downward swing of the semicircular plate, and the easier it is to drain downward quickly. After the water flow becomes smaller, the semicircular plate will tilt up again and close the outer ring under the action of the balancing part.

[0007] During specific use, when it rains or there is a need for drainage, the lock pin is separated from the lock hole. When the rainwater becomes heavier, the semicircular plate is automatically pressed down, thereby opening a channel for downward drainage. Since the upper layer is a retaining net layer, it can ensure that rainwater flows downward fully, preventing pedestrians, vehicles or garbage from falling down.

[0008] Preferably, a spring is provided between the end of the balancing member and the semicircular plate on the other side.

[0009] Preferably, the spring is provided with an anti-corrosion layer. Since the spring is often in contact with rainwater, the use of corrosion resistance can increase the service life.

[0010] Preferably, a drainage gap is provided between the diameter edges of the two semicircular plates to facilitate drainage, and when the rain is not heavy, the semicircular plates do not need to be opened to drain the water.

[0011] Preferably, the semicircular plate is provided with a strip-shaped hole corresponding to the lock pin, and the lock pin is provided with a toggle member, and the toggle member is located in the strip-shaped hole, so that the toggle member can be operated from above to drive the lock pin to slide and separate from the lock hole.

[0012] Preferably, the lock further comprises a battery, an electromagnet, a flow sensor, and a controller. The battery, electromagnet, and flow sensor are electrically connected to the controller. The output end of the electromagnet is connected to the lock pin. When the electromagnet is powered off, the lock pin engages with the lock hole. The flow sensor detects the flow of rainwater to determine the amount of rain. If the rain is too heavy, the electromagnet is activated to drive the lock pin to separate from the lock hole.

[0013] Preferably, the semicircular plate is provided with a water seepage hole, and the flow sensor is arranged below the water seepage hole, so as to accurately detect the size of the rainwater.

[0014] Preferably, the barrier layer is made of metal to ensure sufficient strength.

[0015] Beneficial effects of the utility model:

[0016] This solution can automatically open the drainage channel when the rain is too heavy and automatically close the drainage channel when the rain is light. It will not affect pedestrians and vehicles, is safer and more reliable, and saves manpower. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown, a rainwater manhole cover with automatic flood discharge includes an outer ring 1; a retaining mesh layer 2 and a flood discharge layer are provided inside the outer ring 1; the retaining mesh layer 2 is located on the upper part of the flood discharge layer; the outer edge of the retaining mesh layer 2 is detachably adapted to the outer ring 1; the flood discharge layer includes two semicircular plates 3, the diameter edge of the semicircular plate 3 is provided with a rotating shaft 9, the rotating shaft 9 is rotatably matched with the outer ring 1, and a balancing member 4 is provided on the lower part of the semicircular plate 3 extending toward the lower part of the other semicircular plate 3, the balancing member 4 drives the outer edge of the semicircular plate 3 to tilt and engage with the outer ring 1, the semicircular plate 3 is provided with a locking pin 6, and the inner wall of the outer ring 1 is provided with a lock hole corresponding to the locking pin 6.

[0024] Since the semicircular plate 3 is tilted up by the balancing member 4 and then cooperates with the outer ring 1, when the outer edge of the semicircular plate 3 is subjected to downward pressure, it will swing downward, thereby opening a channel for rainwater to flow downward. The heavier the rain, the greater the amplitude of the downward swing of the semicircular plate 3, and the easier it is to drain downward quickly. After the water flow becomes smaller, under the action of the balancing member 4, the semicircular plate 3 will tilt up again to close the outer ring 1.

[0025] During specific use, when it rains or there is a need for drainage, the lock pin 6 is separated from the lock hole. When the rainwater becomes heavy, the semicircular plate 3 is automatically pressed down, thereby opening a channel for downward drainage. Since the upper layer is the retaining net layer 2, it can ensure that rainwater flows downward fully, preventing pedestrians, vehicles or garbage from falling down.

[0026] A spring 5 is provided between the end of the balance member 4 and the semicircular plate 3 on the other side. The spring 5 is provided with an anti-corrosion layer. Since it is often in contact with rainwater, the use of corrosion resistance can increase the service life.

[0027] A drainage gap is provided between the diameter edges of the two semicircular plates 3. This makes it easy to drain water, and when the rain is not heavy, there is no need to open the semicircular plates 3 to drain water.

[0028] The semicircular plate 3 is provided with a strip hole 7 corresponding to the lock pin 6, and the lock pin 6 is provided with a toggle 8, which is located in the strip hole 7. It is convenient to operate the toggle 8 from the top to drive the lock pin 6 to slide and separate from the lock hole.

[0029] The barrier layer 2 is made of metal to ensure sufficient strength.

[0030] Beneficial effects of the utility model:

[0031] This solution can automatically open the drainage channel when the rain is too heavy and automatically close the drainage channel when the rain is light. It will not affect pedestrians and vehicles, is safer and more reliable, and saves manpower.

[0032] Example 2

[0033] Compared to Example 1, this embodiment further includes the following distinguishing technical features: it also includes a battery, an electromagnet 10, a flow sensor 11, and a controller. The battery, electromagnet 10, and flow sensor 11 are each electrically connected to the controller. The output end of the electromagnet 10 is connected to the lock pin 6. When the electromagnet 10 is powered off, it controls the engagement of the lock pin 6 with the lock hole. The flow sensor 11 detects the flow rate of rainwater, thereby determining the amount of rainwater. If the rainwater is too heavy, the electromagnet 10 is activated to drive the lock pin 6 away from the lock hole.

[0034] The semicircular plate 3 is provided with a water seepage hole 12, and the flow sensor 11 is arranged below the water seepage hole 12, so as to accurately detect the size of the rainwater.

[0035] It should be noted that this solution is suitable for places with fewer pedestrians and vehicles. Of course, it does not matter if there are pedestrians and vehicles, because there is a retaining net layer to provide support. When there is no rain, the semicircular plate can also provide support, increase strength, and prevent impurities from falling. When there is a lot of rain, in order to drain water in time, a small amount of garbage can be allowed to fall in, and the possibility of large-scale blockage due to rainwater is relatively low.

[0036] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
