Description

Technical Field

[0001] The utility model relates to the technical field of urban road manhole waterlogging monitoring, in particular to an urban road waterlogging detection and alarm device. Background Technique

[0002] Urban waterlogging is likely to occur during the annual plum rain season, seriously affecting the smoothness of urban traffic. To facilitate the municipal department to make an emergency response to urban waterlogging in a timely manner, actively organize personnel to intervene, and reduce waterlogging disasters, the current road waterlogging monitoring device adopts the method of setting up a waterlogging monitoring station on the urban road surface, and monitors the water accumulation on the road surface through an ultrasonic water level gauge. However, this method of detecting the water surface of water accumulation is not reliable.

[0003] For example, a Chinese utility model patent with the publication number of CN219776841U discloses an intelligent waterlogging monitoring device for urban waterlogging, including a riser pipe and a driving unit. The controller is arranged at the lower end of the rear side wall of the protective box, and the output end of the radar water level gauge is connected to the input end of the controller. For the intelligent waterlogging monitoring device for urban waterlogging, the cross bar for fixing the radar water level gauge can rotate, thereby increasing the detection range of the radar water level gauge and ensuring the accuracy of detection. However, this radar water level gauge will alarm as long as there is a water surface, that is, if a semi-trailer truck with a panel body stays under the radar water level gauge, the water accumulation in its open carriage can also cause an alarm. In addition, the urban road surface is often uneven and potholes are very common. The water accumulation in local potholes is not enough to reflect the severity of the overall road waterlogging, and it cannot support effective decision-making data during the plum rain season. In view of this, an urban road waterlogging detection and alarm device that can solve the above problems is proposed. Content of the Utility Model

[0004] To solve the technical problem of monitoring the waterlogging of road manholes, the utility model provides an urban road waterlogging detection and alarm device.

[0005] The utility model is realized by adopting the following technical solutions: an urban road waterlogging detection and alarm device, including a first threaded sleeve, a top block is threadedly sleeved on the upper side of the first threaded sleeve, an installation and fixing mechanism is arranged on the lower side of the first threaded sleeve, a limiting cylinder is fixedly connected to the upper side of the top block, a pressure-sensitive sensor is slidably connected inside the limiting cylinder, a wiring assembly is arranged outside the pressure-sensitive sensor, the pressure-sensitive sensor is cooperatively arranged with the top block, a limiting slide bar is fixedly connected to the upper side of the pressure-sensitive sensor, a limiting support mechanism is arranged on one side of the limiting slide bar, and a slide bar driving mechanism for making the pressure-sensitive sensor rush towards the top block is arranged at the upper end of the limiting slide bar.

[0006] As a further improvement of the above solution, the installation and fixing mechanism includes a connecting plate fixedly connected to the lower side of the first threaded sleeve. One side of the connecting plate away from the first threaded sleeve is fixedly connected with a mounting plate, and bolt holes are formed in the mounting plate for fixedly connecting with the inner wall of the road sewage well.

[0007] As a further improvement of the above solution, the limiting and supporting mechanism includes a second threaded sleeve fixedly connected to the upper side of the limiting cylinder. The inner side of the second threaded sleeve is threadedly sleeved with a limiting sleeve, and the inner side of the limiting sleeve is slidably connected with the limiting slide rod.

[0008] As a further improvement of the above solution, the slide rod driving mechanism includes a waterproof housing threadedly sleeved on the outer side of the second threaded sleeve. A grooved slot is formed on the outer side of the waterproof housing, and a connecting arm is rotatably connected to the inner side of the grooved slot. One end of the connecting arm away from the waterproof housing is rotatably connected with a buoyancy ball, and a latch mechanism for pushing the limiting slide rod to move up and down is arranged at the other end of the connecting arm.

[0009] As a further improvement of the above solution, the latch mechanism includes a latch fixedly connected to one end of the limiting slide rod close to the waterproof housing. A stop block is fixedly connected to the upper end of the limiting slide rod, and the latch is movably connected between the stop block and the limiting slide rod.

[0010] As a further improvement of the above solution, when the road sewage well in the city is flooded, the water level in the well rises. The buoyancy ball rises, the limiting slide rod is pushed downward, and the pressure-sensitive sensor is pushed to collide with the top block. The pressure-sensitive sensor generates a change in the piezoresistor to generate an electrical signal, and remotely communicates with the monitoring terminal to respond to the urban waterlogging early warning.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model cooperates with each other through the buoyancy ball, the connecting arm, the latch, the stop block, the limiting slide rod, and the pressure-sensitive sensor. When waterlogging occurs on the urban road, the water level in the sewage well rises to a certain threshold, higher than the buoyancy ball. At this time, under the action of its own buoyancy, the buoyancy ball pulls the connecting arm to rotate upward along with the water level. The latch pushes the limiting slide rod to move downward, so that the pressure-sensitive sensor collides with the top block. An alarm signal is generated through the change of the piezoresistor, which can avoid the interference of the change of the external water surface, and the monitored water surface data is more real and reliable;

[0013] 2. The present utility model cooperates with each other through the mounting plate, the connecting plate and the first threaded sleeve, so that the urban road water accumulation detection and alarm device can be installed inside the sewage well. Due to the protection of the road sewage well cover above, the service life of the water level monitoring and alarm device is longer and it is easier to maintain. Description of the Drawings

[0020] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be combined arbitrarily to form new embodiments.

[0021] Embodiment:

[0022] Please combine Figures 1-4 , a device for detecting and alarming urban road waterlogging in this embodiment includes a first threaded sleeve 3. A top block 13 is threadedly sleeved on the upper side of the first threaded sleeve 3. An installation and fixing mechanism is arranged on the lower side of the first threaded sleeve 3. The installation and fixing mechanism is used to connect the alarm device to the inner wall of the sewer well. A limiting cylinder 4 is fixedly connected to the upper side of the top block 13. A pressure-sensitive sensor 9 is slidably connected to the inner side of the limiting cylinder 4. A wiring assembly is arranged on the outer side of the pressure-sensitive sensor 9. The pressure-sensitive sensor 9 is cooperatively arranged with the top block 13, that is, when waterlogging occurs and the water level in the sewer well rises, the pressure-sensitive sensor 9 is pressed down to come into contact with the top block 13 and apply pressure; when there is no urban waterlogging and the water level in the sewer well remains unchanged, at this time, the pressure-sensitive sensor 9 is separated from the top block 13. A limiting slide bar 12 is fixedly connected to the upper side of the pressure-sensitive sensor 9. A limiting support mechanism is arranged on one side of the limiting slide bar 12. A slide bar driving mechanism for making the pressure-sensitive sensor 9 rush towards the top block 13 is arranged at the upper end of the limiting slide bar 12.

[0023] Please combine Figure 1As shown in the figure, the installation and fixing mechanism includes a connecting plate 2 fixedly connected to the lower side of the first threaded sleeve 3. On the side of the connecting plate 2 away from the first threaded sleeve 3, there is an installation plate 1. Bolt holes are provided on the installation plate 1 for fixedly connecting to the inner wall of the road sewer well. By setting the first threaded sleeve 3, it is convenient for future disassembly and replacement of relevant components. Both the installation plate 1 and the connecting plate 2 are made of engineering plastics, with excellent corrosion resistance and certain mechanical strength.

[0024] Please refer to Figure 2 As shown in the figure, the limiting and supporting mechanism includes a second threaded sleeve 5 fixedly connected to the upper side of the limiting cylinder 4. The inner side of the second threaded sleeve 5 is threadedly sleeved with a limiting sleeve 10. The inner side of the limiting sleeve 10 is slidably connected to a limiting slide bar 12. The limiting sleeve 10 is of a detachable design for easy replacement. A limiting channel is provided inside the limiting sleeve 10 to provide space for the up and down movement of the limiting slide bar 12.

[0025] Please refer to Figure 2 As shown in the figure, the slide bar driving mechanism includes a waterproof housing 6 threadedly sleeved on the outer side of the second threaded sleeve 5. The waterproof housing 6 is made of engineering plastics. A sealing component is provided at the gap in contact with the connecting arm 7. Grooves are provided on the outer side of the waterproof housing 6. A connecting arm 7 is rotatably connected to the inside of the grooves. The connecting arm 7 is of an arcuate structure and is made of engineering plastics. One end of the connecting arm 7 away from the waterproof housing 6 is rotatably connected to a buoyancy ball 8. The buoyancy ball 8 is made of macromolecular hollow plastics and has a large buoyancy. When it rises when encountering water, it can generate sufficient buoyancy. A latch mechanism for pushing the limiting slide bar 12 up and down is provided at the other end of the connecting arm 7.

[0026] Please refer to Figure 3 and Figure 4 As shown in the figure, the latch mechanism includes a latch pin 14 fixedly connected to the end of the limiting slide bar 12 close to the waterproof housing 6. A stopper 11 is fixedly connected to the upper end of the limiting slide bar 12. The latch pin 14 is movably connected between the stopper 11 and the limiting slide bar 12. Please refer to Figure 4 As shown in the figure, at the place where the limiting slide bar 12 contacts the latch pin 14, corresponding split grooves are provided on both sides of the limiting slide bar 12, so that the latch pin 14 can exert an abutting effect on the lower side of the split grooves.

[0027] When the road sewer well in the city is flooded, the water level in the well rises. The buoyancy ball 8 rises, and the limiting slide bar 12 is pushed down, pushing the pressure - sensitive sensor 9 to collide with the top block 13. The pressure - sensitive sensor 9 generates a change in piezoresistance to generate an electrical signal, and remotely communicates with the monitoring terminal for urban waterlogging early warning response.

[0028] In the embodiment of the present application, the implementation principle of a device for detecting and alarming waterlogging on urban roads is as follows: When there is urban waterlogging, the water level in the sewer well beside the road will surely rise. At this time, the buoyancy ball 8 rises, driving the connecting arm 7 to swing upward. The connecting arm 7 pushes the latch 14 to swing downward. Due to the clamping relationship between the latch 14 and the limit slide rod 12, at this time, the latch 14 presses down to push the limit slide rod 12 to move downward. The limit slide rod 12 slides downward along the inner side of the limit sleeve 10, driving the pressure-sensitive sensor 9 to collide with the top block 13 on the second thread sleeve 5, causing a change in the resistance of the pressure-sensitive sensor 9. This resistance change forms a change in the electrical signal, which is remotely communicated to the control center to form an early warning of urban waterlogging.

[0029] The above-mentioned implementation manner is only the preferred implementation manner of the present utility model and cannot be used to limit the scope of protection of the present utility model. Any non-substantive changes and substitutions made by those skilled in the art on the basis of the present utility model fall within the scope of protection required by the present utility model.
