Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, and particularly relates to an intelligent manhole cover with dual alarms. Background Art

[0002] A manhole cover is a lid covering a wellhead, usually made of metal, concrete or composite materials. There are many underground facilities in cities, such as drainage pipes, communication cable channels, gas pipelines, etc. These facilities are usually connected to the ground through wellheads. The manhole cover can cover the wellhead to prevent pedestrians, vehicles or other objects from accidentally falling into the well, avoiding casualties and property losses. Especially on roads, without a manhole cover, the wellhead will become a huge safety hazard, which may cause pedestrians and vehicles to fall into it, leading to serious traffic accidents.

[0003] With the continuous development of cities, manhole covers, as an important part of urban infrastructure, play a key role in road, drainage and other systems. However, there are many problems in the use of traditional manhole covers. For the water level situation under the manhole cover, traditional manhole covers cannot effectively monitor and give early warnings. In bad weather such as heavy rain, once there is a problem with the drainage system, the water level under the manhole cover may rise rapidly, but the relevant departments cannot know this situation in time, which is likely to lead to disasters such as urban waterlogging, posing a great threat to people's lives and property safety. When the manhole cover is accidentally opened, traditional manhole covers do not have an effective warning device, and pedestrians passing by are easily unaware and fall into the well, causing serious personal injuries. Content of the Utility Model

[0004] In order to solve the deficiencies of the prior art, this application provides an intelligent manhole cover that can give early warnings about the water level under the manhole cover, can provide warnings for pedestrians when the manhole cover is opened, and can prevent pedestrians from falling from the wellhead.

[0005] The utility model discloses a smart manhole cover with dual alarms. The smart manhole cover includes an outer frame, a cover body, a driven ball, a water level alarm component, a sound - emitting component, a control component and a power supply. One side of the cover body is hinged to the outer frame. The cover body includes a hollow accommodation cavity and an elastic component arranged on one side of the bottom of the accommodation cavity. The accommodation cavity has an inclined bottom surface and penetrates from below. The elastic component includes an elastic part and a pushing part. One end of the elastic part is connected to the cover body, and the other end of the elastic part is connected to the pushing part. The driven ball is movably arranged in the accommodation cavity of the cover body. The driven ball includes a driven rod with one end connected to the driven ball and a driving ball connected to the other end of the driven rod. The driven rod extends out of the accommodation cavity through the penetration below the accommodation cavity. One side of the accommodation cavity near the bottom is recessed upward to form an alarm cavity. The water level alarm component is arranged in the alarm cavity. The sound - emitting component is arranged on the side of the accommodation cavity away from the elastic component. The control component is arranged at the lower part of the outer frame. The control component is connected to the water level alarm component and the sound - emitting component. The power supply is arranged at the lower part of the outer frame. The power supply is electrically connected to the water level alarm component, the sound - emitting component and the control component.

[0006] Further, the lower side of the outer frame includes an outer frame track and an anti - fall component arranged in the outer frame track. The anti - fall component includes a plurality of telescopic anti - fall rods and a plurality of hinges for connecting the telescopic rods. Both ends of the anti - fall rods are arranged in the outer frame track. The anti - fall component includes an anti - fall through - hole for the driven rod to pass through.

[0007] Further, taking the plane extending from the cover body as the horizontal plane, the width of the projection of the alarm cavity on the horizontal plane is greater than the projection of the driven ball on the horizontal plane.

[0008] Taking the plane perpendicular to the horizontal plane as the vertical plane, the elastic force of the elastic component acting on the driven ball in the vertical plane is 70% - 80% of the self - gravity of the driven ball in the vertical plane.

[0009] Further, the driving ball is hollow inside. The driven ball includes a driven limit component, and the driven limit component is arranged on the driven rod on the side of the outside of the accommodation cavity near the hinged part of the cover body and the outer frame.

[0010] Further, a strengthening component is arranged on the side of the cover body close to the power supply.

[0011] Further, a wireless communication module is arranged inside the control component.

[0012] Further, anti - slip patterns are arranged on the side of the cover body away from the power supply.

[0013] The intelligent manhole cover of the present application can effectively monitor and give early warnings about the water level situation under the manhole cover. When the water level rises and touches the driving ball, the driving ball drives the driven ball to move upward under the buoyancy force, triggering the water level alarm component to give an alarm, and sending an alarm to the staff through the control component, providing timely early warnings for dealing with the rising water level situation, helping to prevent disasters such as urban waterlogging, and ensuring the safety of people's lives and property. When the manhole cover body is directly opened, the driven ball abuts against the sound-making component to make a sound, reminding passersby and preventing them from falling. The intelligent manhole cover can give two different alarms according to the state of the manhole cover and the water level state under the manhole cover, and two different styles of alarms can be set during alarm setting for distinguishing reminders.

[0014] The present application is also provided with an anti-falling component to provide a second line of protection for pedestrians. When the manhole cover is in normal use, the cover body provides the first line of defense. When an accident occurs to the manhole cover, the anti-falling component serves as the second line of defense to prevent pedestrians from falling into the well, greatly improving the safety protection level for pedestrians and vehicles, and effectively reducing the risk of casualties and property losses caused by manhole cover problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to enable those skilled in the art to better understand the solutions of the present utility model, the technical solutions in the specific embodiments of the present utility model will be clearly and completely described below.

[0021] The present application discloses an intelligent manhole cover 100 with dual alarms, as shown in Figure 1As shown, the intelligent manhole cover 100 includes an outer frame 11, a cover body 12, a driven ball 13, a water level alarm member 14, a sound generating member 15, a control member 16, and a power supply 17. One side of the cover body 12 is hinged to the outer frame 11. The outer frame 11 can firmly fix the cover body 12 at the wellhead, preventing the cover body 12 from moving, misaligning, or flipping under the heavy pressure of vehicles and pedestrians, maintaining the flatness and safety of the road, and reducing the risks of traffic accidents and pedestrian falls caused by the loosening of the cover body 12. The cover body 12 includes a hollow accommodation cavity with an inclined bottom surface and penetrating from below, and an elastic member 121 provided on one side of the bottom of the accommodation cavity, such as Figure 2 and Figure 3As shown, the elastic member 121 includes an elastic portion 1211 and a pushing portion 1212. One end of the elastic portion 1211 is connected to the cover body 12, and the other end of the elastic portion 1211 is connected to the pushing portion 1212. The driven ball 13 is movably arranged in the accommodation cavity of the cover body 12. The driven ball 13 is used to move in the accommodation cavity inside the cover body 12. When the cover body 12 is horizontal, the driven ball 13 moves to the lower part in the accommodation cavity and abuts against the elastic member 121. When the cover body 12 is inclined, the driven ball 13 moves in the accommodation cavity until it reaches the upper part in the accommodation cavity. The driven ball 13 includes a driven rod 131 with one end connected to the driven ball 13 and a driving ball 132 connected to the other end of the driven rod 131. The driven rod 131 extends out of the accommodation cavity through the through hole below the accommodation cavity. The driving ball 132 is used to contact the water body below the cover body 12. When the water level below the cover body 12 rises and contacts the driving ball 132, the driving ball 132 is subjected to the buoyancy force. At this time, the driving ball 132 drives the driven ball 13 to move upward. One side of the accommodation cavity near the bottom is recessed upward to form an alarm cavity. The water level alarm member 14 is arranged in the alarm cavity. The water level alarm member 14 is electrically connected to the power supply 17 and the control member 16. When the driving ball 132 is subjected to the buoyancy force and drives the driven ball 13 to move upward until the driven ball 13 moves into the alarm cavity and abuts against the water level alarm member, at this time the water level alarm member issues a water level alarm and sends an alarm to the staff through the control member 16. The accommodation cavity is for placing the water level alarm member on the one hand and positioning the driven ball 13 on the other hand, preventing the driven ball 13 from moving to the upper part in the accommodation cavity under the upward buoyancy force. The elastic member 121 is to provide a certain upward force to the driven ball 13, so that the driving ball 132 can move upward and abut against the water level alarm member with a smaller buoyancy force on the driven ball 13. The sounding member 15 is arranged on the side of the accommodation cavity away from the elastic member 121. When the cover body 12 of the manhole cover is directly opened, since the driven ball 13 is not subjected to an upward force but only a combined downward force, at this time the driven ball 13 moves downward along the bottom of the accommodation cavity until it abuts against the sounding member. After abutting against the sounding member, the sounding member keeps sounding, reminding passers-by and sending a reminder to prevent passers-by from falling. The control member 16 is arranged at the lower part of the outer frame 11. The control member 16 is connected to the water level alarm member 14. The control member 16 is used to send the water level alarm to the staff to provide an early warning for the staff. The power supply 17 is arranged at the lower part of the outer frame 11. The power supply 17 is electrically connected to the water level alarm member 14 and the control member 16. The intelligent manhole cover 100 of the present application can effectively monitor and give an early warning of the water level condition below the manhole cover. When the water level rises and contacts the driving ball 132, the driving ball 132 is driven by the buoyancy force to drive the driven ball 13 to move upward, triggering the water level alarm member 14 to issue an alarm and sending an alarm to the staff through the control member 16, providing a timely early warning for dealing with the rising water level situation, helping to prevent disasters such as urban waterlogging and ensuring the safety of people's lives and property.When the manhole cover body 12 is directly opened, the driven ball 13 abuts against the sound - making member 15 to make a sound, reminding passers - by and preventing pedestrians from falling. The intelligent manhole cover 100 can issue two different alarms according to the state of the manhole cover and the water level state below the manhole cover. Two different styles of alarms can be set during alarm setting for differentiation and reminder.

[0022] As an implementation manner, as Figure 4 shown, the lower side of the outer frame 11 includes an outer frame 11 track and an anti - falling member 111 arranged in the outer frame 11 track. The anti - falling member 111 includes a number of telescopic anti - falling rods and a number of hinges 1112 for connecting the telescopic rods. The two ends of the anti - falling rods are arranged in the outer frame 11 track. The anti - falling member 111 includes an anti - falling through - hole for the driven rod 131 to pass through. The anti - falling member 111 is used to provide protection for pedestrians when the manhole cover is opened. When the manhole cover is in normal use, the cover body 12 itself can prevent pedestrians and vehicles from falling. When an accident occurs to the manhole cover, such as damage, illegal opening or displacement of the cover body 12, the anti - falling member 111 can serve as a second line of defense to prevent people and objects from falling into the well. The structure of the telescopic anti - falling rods and the hinges 1112 enables the anti - falling member 111 to contract in the outer frame 11 track. When the staff needs to carry out underground operations in the well, the anti - falling member 111 can be contracted to one side. When the underground operation of the staff is completed, the anti - falling member 111 can be pulled to make the anti - falling member 111 move in the outer frame 11 track until the anti - falling member 111 is opened, so as to restore the protection function for pedestrians. The arranged through anti - falling through - hole ensures that the driven rod 131 can normally pass through the anti - falling member 111 without affecting the water level monitoring and alarm functions of the intelligent manhole cover 100. The driven rod 131 can freely move in the anti - falling through - hole when needed, trigger the water level alarm member 14 or the sound - making member 15, and realize the accurate monitoring of the manhole cover state and the water level condition.

[0023] As an implementation manner, taking the plane extended by the cover body 12 as the horizontal plane, the width of the projection of the alarm cavity on the horizontal plane is greater than the projection of the driven ball 13 on the horizontal plane. This setting is to ensure that the alarm cavity can position the driven ball 13 and prevent the driven ball 13 from moving to the higher side of the accommodation cavity under the action of buoyancy. Taking the plane perpendicular to the horizontal plane as the vertical plane, the elastic force of the elastic member 121 on the driven ball 13 in the vertical plane is 70% - 80% of the self - gravity of the driven ball 13 in the vertical plane. This setting is to enable the elastic member 121 to provide sufficient force for the driven ball 13 in the vertical direction, so that when the intelligent manhole cover 100 is actually used, the water level below only needs to reach the driving ball 132 to drive the driving ball 132 to move upward, thereby enabling the driven ball 13 to abut against the water level alarm member to issue an alarm.

[0024] As an implementation manner, the driving ball 132 is hollow inside. When the water level below the manhole cover rises, the hollow driving ball 132 can be more easily affected by the buoyancy of water. Due to the hollow structure, the overall density of the driving ball 132 is reduced, and it receives a greater buoyancy force under the same volume. In this way, even if the water level rises slightly, it can drive the driven ball 13 to move upward more quickly, trigger the water level alarm, and improve the sensitivity of water level monitoring. The driven ball 13 is provided with a driven limit member 133, and the driven limit member 133 is arranged on the driven rod 131 on the side of the receiving cavity close to the hinge outer frame 11 of the cover body 12. The driven limit member 133 is arranged on the driven rod 131 on the side of the receiving cavity close to the hinge outer frame 11 of the cover body 12, which can limit the moving range of the driven ball 13. When the cover body 12 is in an inclined state, the driven ball 13 moves in the receiving cavity. Without the limit member, the driven ball 13 may move excessively to an inappropriate position, affecting the normal operation of the device.

[0025] As an implementation manner, a reinforcing member 123 is arranged on the side of the cover body 12 close to the power source 17. During the use of the manhole cover, it may be subject to external impacts such as vehicle rolling and heavy object impact. The arrangement of the reinforcing member 123 can significantly improve the strength of the cover body 12 on the side close to the power source 17, enabling it to better withstand these external forces, reducing the damage of the cover body 12 caused by the impact, and thus protecting the internal power source 17 and other components.

[0026] As an implementation manner, a wireless communication module is provided inside the control member 16. The wireless communication module is used to remotely send the water level alarm to the staff, providing remote early warning for the staff.

[0027] As an implementation manner, anti-slip patterns are arranged on the side of the cover body 12 away from the power source 17. The anti-slip patterns are used to prevent pedestrians from slipping. In wet, rainy, snowy weather and other situations, the surface of the manhole cover is likely to become slippery. Arranging anti-slip patterns on the side of the cover body 12 away from the power source 17 can increase the friction force, greatly reducing the risk of pedestrians slipping when passing by the manhole cover. Especially in areas with a large flow of people, such as sidewalks and pedestrian streets, it can effectively ensure the safety of pedestrians.

[0028] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
