Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of municipal public well lid facilities, and particularly relates to a variable-color inspection well lid. BACKGROUND

[0002] With the advancement of urbanization, municipal public infrastructure construction is developing rapidly. Among them, various municipal well facilities are widely used in various industries as common municipal facilities, such as power communication wells widely used by power and communication departments, sewage wells widely used by municipal environmental protection and residential areas, inspection wells in municipal road facilities, rainwater wells, and sewer wells in sewage treatment facilities, etc. The number is huge, and tragedies of pedestrians falling and being injured due to the loss or damage of well covers often occur. Especially, if such phenomenon occurs in crowded urban streets, pedestrian streets or tourist attractions, the consequences are self-evident. Therefore, for various well cover facilities used in urban streets, pedestrian streets or tourist attractions, the position status of the well cover needs to be clearly displayed to remind pedestrians. On the other hand, the installed well cover facility also needs to be coordinated with the surrounding environment of the urban street, pedestrian street or tourist attraction, and can increase the environmental aesthetics or even become a viewing point. How to achieve this purpose and effect is a problem faced by municipal public facilities and a problem that needs to be concerned by technical personnel in the field.

[0003] At present, a lamp light well cover and an intelligent control system with the announcement number CN105376914A on the market include a well seat and a well cover. The well cover is a hollow structure, and a light-transmitting glass plate and a lamp group are arranged in the well cover. The intelligent monitoring system includes a photosensitive element, a micro-processing controller, a light adjusting controller, a light sensor, a monitoring center and an alarm device. The invention uses the sensing signal emitted by the photosensitive element in response to the ambient brightness to process the signal through the micro-processing controller or the single-chip microcomputer and issue an instruction to control the lamp group to emit light, thereby indicating the position of the well cover facility for pedestrians and tourists, and increasing the urban landscape. It has the characteristics of clear display of well cover position status information, large light monitoring area, large number of covered well covers, real-time and accurate information, reliable work, good light visual effect, intelligent control, low power consumption, etc. It can not only display the position status of the well cover, but also increase the aesthetic landscape of the urban environment. It is an effective method for managing municipal public facilities by using intelligent technology.

[0004] However, there are some problems: 1. The light of the device only has the effect of being beautiful and displaying the position, and lacks the warning effect when the well cover is damaged, which cannot effectively remind the staff to repair. 2. The device has no remedial measures when pedestrians or animals do not pay attention or cannot understand the light and fall into the broken or well cover-free well. At this time, a device is needed to protect pedestrians and animals. SUMMARY

[0005] The application provides a variable color inspection well cover to solve the problem of lack of early warning effect when the cover is damaged.

[0006] The application provides a variable color inspection well cover, which comprises a cover arranged on a well wall, wherein the cover is provided with a lamp groove; a processor for processing an electric signal, which is arranged inside the cover; a power supply, which is fixedly connected with the processor and electrically connected with the processor; a light sensor, which is fixedly connected with the cover and electrically connected with the processor; an LED lamp, which has multiple light sources, is fixedly connected with the lamp groove and is electrically connected with the light sensor; and a supporting mechanism, which is arranged below the cover and is fixedly connected with the well wall; and the light sensor is arranged inside the cover.

The sealed cover can effectively prevent garbage and water from flowing into the inspection well. In a normal use state, the light sensor is located inside the cover, and there is no light source inside, so the light sensor is not triggered, the LED lamp has multiple light sources, and the processor controls the LED lamp to emit warm light. When the cover is damaged, light will penetrate into the well, sunlight or light from street lamps at night will penetrate into the well, and when the light intensity of the light sensor reaches a set value, the light sensor will be triggered, so that the LED lamp emits red light, reminding pedestrians not to step on it, and the processor will send information to the staff to remind them to come and repair it. If a person or an animal falls into the well, the supporting mechanism can also support the person or the animal from falling to the bottom of the well.

[0008] The application has the following beneficial effects: 1. The cover damage can be early warned, effectively reminding the staff to repair it; and 2. When a person falls into the well, the supporting mechanism can perform simple rescue.

[0009] Further, the supporting mechanism comprises a supporting frame and a floating plate, the supporting frame is provided with filter holes, and the supporting frame cooperates with the floating plate. When it is raining, garbage and water may penetrate into the connection between the cover and the well wall, at which time the garbage will be left on the floating plate, and the water will flow away from the filter holes, so that the drainage pipeline is not blocked.

[0012] Further, the adjusting mechanism is further included, the annular cylinder includes a cylinder body, a second piston, a spring and a push rod, the second piston is in sliding connection with the cylinder body, one end of the push rod is in fixed connection with the second piston, the other end of the push rod is in fixed connection with the sealing ring, one end of the spring is in fixed connection with the piston, and the other end of the spring is in fixed connection with the cylinder body, the adjusting mechanism includes a fixed plate, a stop block and a first piston, the well lid is provided with a cylinder groove and a drainage outlet, the well wall is provided with a fixed groove, the cylinder groove is in communication with the cylinder body, the first piston is in sliding connection with the cylinder groove, the first piston is in fixed connection with the fixed plate, the fixed plate is in fixed connection with the stop block, and the stop block is used for sealing the drainage outlet, the fixed plate cooperates with the fixed groove, and the stop block is in sliding connection with the drainage outlet.

[0013] When the inspection well is flooded, if the inspection well cover adopts a sealing structure, the cover is easily washed away by water pressure, but if a drainage port is provided, garbage and water flow will easily enter, and the foul smell inside the well will also be emitted, causing environmental pollution. When there is no flooding, the blocking piece is located at the drainage port, blocking the drainage port to prevent garbage and water from entering the inspection well, and prevent the internal foul smell from being emitted. When the well is flooded, the floating plate will rise, and the push rod will rise at the same time, the second piston will rise, the gas in the cylinder body will be squeezed, the gas will enter the cylinder groove, the pressure in the cylinder groove will increase, the first piston will move, the fixed plate will move, the fixed plate will be inserted into the fixed groove, which can effectively prevent the cover from being washed away by the water flow, and the fixed plate will move the blocking piece, so that the drainage port is opened for internal water flow drainage. At the same time, the sealing ring will form a closed environment with the ring-shaped cylinder, preventing the light sensor from being triggered due to the opening of the drainage port, so that the staff misjudge.

[0014] Further, a pressure sensor is further included, the pressure sensor is fixedly connected with the cylinder body, the pressure sensor cooperates with the second piston, and the pressure sensor is electrically connected with the processor. However, when the floating plate in the well is filled with too much garbage, the floating plate will move down, and the second piston will move down when the floating plate moves down, and the second piston will squeeze the pressure sensor, so that the pressure sensor is triggered, the processor controls the led lamp to turn yellow, reminding the staff that the floating plate in the well needs to be cleaned.

[0027] As shown in the accompanying drawings: Figure 1 , Figure 2

[0028] ​The principle of the scheme is that the inspection well drainage of the scheme is drained through the drainage well. Under normal conditions, the stop block 7 is located at the drainage port 8, blocking the drainage port 8, and a sealing layer 3 is arranged between the well cover 1 and the well wall 2, so that the well cover 1 and the well wall 2 form a sealed structure. The sealed well cover 1 can effectively prevent garbage and water from flowing into the inspection well, and prevent the internal odor from being emitted. In the normal use state, the light sensor 23 is located inside the well cover 1, and there is no light source inside, so the light sensor 23 is not triggered, and the processor 19 controls the led lamp 24 to emit warm light. When the well cover 1 is damaged, light will penetrate into the well, the light sensor 23 will be triggered, the led lamp 24 will emit red light, reminding pedestrians not to step on, and the processor 19 will send information to the staff, reminding the staff to repair. And if a person or an animal falls into the well, the floating plate 14 can also support the person or the animal from falling to the bottom of the well.

[0029] When the garbage on the floating plate 14 in the well is too much, the floating plate 14 will move down, and the second piston 20 will move down when the floating plate 14 moves down. The second piston 20 will press the pressure sensor 13, so that the pressure sensor 13 is triggered, and the processor 19 controls the led lamp 24 to emit yellow light, reminding the staff that the garbage on the floating plate 14 in the well needs to be cleaned.

[0030] When it rains, garbage and water may sometimes penetrate into the connection between the well cover 1 and the well wall 2. At this time, the garbage will be left on the floating plate 14, and the water will flow away from the filter hole 11, without blocking the drainage pipe.

[0031] When the inspection well is flooded, the rising water level will cause the processor 19 to be flooded, causing the device to be damaged. When the water level rises, the floating plate 14 will rise, the floating plate 14 will drive the sealing ring 15 to rise, until the sealing ring 15 contacts the annular air cylinder 17, forming a seal, and the processor 19 and the light sensor 23 are closed in a sealed space, reducing the impact of the water flow. Moreover, the processor 19 and the light sensor 23 are also waterproofed, so that the processor 19 and the light sensor 23 are not easily damaged by the water flow. At the same time, the sealing ring 15 drives the trigger block 16 to rise, and when the sealing ring 15 forms a closed state with the annular air cylinder 17, the trigger block 16 contacts the contact sensor 18, so that the contact sensor 18 is triggered, and the processor 19 controls the led lamp 24 to emit orange light, reminding pedestrians that the inspection well is flooded, which may cause the well cover 1 to fall off. At the same time, the processor 19 will send information to the staff, reminding the staff to come to solve the problem.

[0032] And when the well inside the waterlogging occurs, the floating plate 14 rises at the same time will make the push rod 22 rises, push rod 22 rises makes the second piston 20 rises, the second piston 20 rises makes the cylinder gas extrusion, makes the gas into cylinder groove 9, cylinder groove 9 pressure becomes big, push the first piston 10 moves, the first piston 10 drives fixed plate 6 moves, makes the fixed plate 6 inserts into fixed slot 5, can effectively prevent the well lid 1 is washed away by the water flow, at the same time fixed plate 6 will drive the stop block 7 moves, makes the drainage port 8 open, carries out internal water flow drainage. At the same time the sealing ring 15 will form airtight environment with annular cylinder, prevent because the drainage port 8 opens and causes the light sensor 23 false triggering, makes the staff misjudgment.

[0033] The beneficial effects of the present scheme are: 1, the well lid 1 plays a warning effect when broken, effectively reminding the staff to repair. 2, when someone falls into the well, the support mechanism can carry out simple rescue. 3, the change of led lamp 24 can inform the staff of the well condition, so that the staff can be prepared when repairing. 4, when waterlogging, the sealing ring 15 can protect the processor 19 and the light sensor 23, and because the drainage port 8 is opened, the sealing ring 15 can prevent the light sensor 23 from being triggered. 5, the well lid 1 of the present scheme can maintain sealing under normal circumstances, prevent garbage and water flow from entering, and prevent odor from flowing out. In the case of waterlogging, the well lid 1 remains connected with the outside world, and excess accumulated water is discharged through the drainage port 8, preventing the well lid 1 from being washed away or the internal water pressure from being too large, causing the well lid 1 to be damaged.

[0034] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application, which will not affect the effect and practicality of the patent.
