Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering, and specifically relates to a multifunctional reminder board. Background Art

[0002] Municipal engineering refers to municipal facility construction projects. During the construction of municipal engineering, sewage pipes will be laid under the road, and manholes will be opened on the road to drain the water on the road. In order to prevent foreign objects or impurities from falling into the pipes through the manholes, manhole covers will be installed on the manholes. When the sewage pipes are blocked, the sewage level inside the pipes will gradually rise, eventually contacting the manhole cover and lifting it up. At this time, the tilted manhole cover will affect moving vehicles, so the staff will place warning signs on the outside of the manhole cover while repairing the pipes to prevent moving vehicles from colliding with the manhole cover. The maintenance cycle of sewage pipes is relatively long, resulting in the manhole covers on the road surface still being lifted up and shifted by sewage during the maintenance process, making it impossible for the manhole covers to continue to protect the manholes.

[0015] See also Figure 1-Figure 3 The utility model provides the following technical solutions: it includes a mounting base 1, a plurality of water inlets 11 are provided at the bottom end of the mounting base 1, a supporting frame 2 is fixedly connected to the top of the mounting base 1, a prompt plate 21 is fixedly connected to the inner side of the supporting frame 2, a lighting lamp 22 is fixedly connected to the top of the supporting frame 2, a limiting bin 3 is provided on the inner side of the supporting frame 2, an entry hole 31 is provided at the bottom end of the limiting bin 3, a pushing plate 32 is slidably connected inside the limiting bin 3, a proximity switch 33 is fixedly connected to the inner wall at the top end of the limiting bin 3, a positioning plate 4 is slidably provided inside the limiting bin 3, a motion guide rod 41 is fixedly connected to the inner wall at the top end of the limiting bin 3, and the positioning plate 4 slides on the outside of the motion guide rod 41.

[0016] In this embodiment: the mounting base 1 is used to support and connect various components, so as to serve as an auxiliary reminder for the moving vehicle. The staff can fix the mounting base 1 to the position outside the manhole cover above the road by means of bolts or the like. The several water inlets 11 opened at the bottom end of the mounting base 1 are used to make space for water to flow into the inside of the mounting base 1, so that when the staff places the mounting base 1 on the outside of the manhole cover, the water flow on the road outside the mounting base 1 can still flow into the inside of the mounting base 1, and the bottom end of the limiting bin 3 is opened with an entry hole 31, so that the water flow inside the mounting base 1 can enter the inside of the limiting bin 3 through the entry hole 31, so that when the staff places the limiting bin 3 above the manhole cover The support frame 2 fixed on the top of the installation base 1 is used to support the reminder board 21, so that the reminder board 21 can be fixed at a suitable height, and the staff can post reminders on the surface of the reminder board 21, so as to achieve the purpose of reminding the moving vehicles. The lighting lamp 22 fixed on the top of the support frame 2 is used to illuminate both sides of the reminder board 21, so that at night, the personnel can still quickly and effectively observe the reminders posted on the surface of the reminder board 21, so as to achieve the purpose of ensuring the reminder effect for the personnel. The limiting bin 3 provided on the inner side of the support frame 2 is used to limit the manhole cover, and the staff can place the limiting bin 3 above the manhole cover. , so that when the manhole cover is lifted up by the water source inside the sewage pipe, the manhole cover will not shift due to the limitation of the limiting bin 3. The pushing plate 32 sliding inside the limiting bin 3 is used to limit the two sides of the manhole cover, so that when the manhole cover is lifted up and tilted, the pushing plate 32 will limit the two sides of the top of the manhole cover, so that the manhole cover cannot be tilted, thereby avoiding the displacement of the manhole cover. The motion guide rod 41 fixed on the inner wall of the top of the limiting bin 3 is used to support and guide the sliding of the positioning plate 4. When the water in the sewage pipe overflows from the manhole cover, it will contact the bottom end of the positioning plate 4 and drive the positioning plate 4 to move through buoyancy. When the positioning plate 4 moves to close to the proximity switch 3 installed on the inner wall of the top of the limiting bin 3 3, the proximity switch 33 will receive the proximity signal of the positioning plate 4, and send a signal to the outside world through the signal transmission module installed inside the limit bin 3, so that the staff can know that the sewage overflows again. The way in which the signal transmission module sends a signal to the outside world is a mature existing technology in this field and is a well-known technology, so it will not be repeated here. Through the cooperation of the supporting frame 2 and the limit bin 3 and other components, while providing auxiliary prompts to the moving vehicle, it can also prevent the manhole cover from being lifted up and tilted, and when the sewage overflows, a signal can be sent to the outside world, so that the staff can quickly learn of the sewage overflow news, which is convenient for the staff to repair the sewage pipeline.

[0017] A connecting block 23 is fixedly connected between the support frame 2 and the limiting bin 3; the connecting block 23 fixed between the support frame 2 and the limiting bin 3 is used to connect and fix the support frame 2 and the limiting bin 3, so that the limiting bin 3 can support and fix the support frame 2, and then when the limiting bin 3 is placed above the manhole cover, the limiting bin 3 can limit the manhole cover to prevent the manhole cover from shifting.

[0018] An auxiliary block 321 is fixedly connected to one side of the pushing plate 32, and a guide groove 34 is provided on the inner wall of the limiting bin 3, and the auxiliary block 321 slides inside the guide groove 34; the auxiliary block 321 fixed on one side of the pushing plate 32 is used to assist the sliding of the pushing plate 32, and the guide groove 34 provided on the inner wall of the limiting bin 3 is used to guide the sliding of the pushing plate 32, and the auxiliary block 321 slides inside the guide groove 34, so that the pushing plate 32 can be guided by the guide groove 34 when sliding, thereby avoiding unnecessary displacement of the pushing plate 32 when sliding.

[0019] A spring 322 is fixedly connected between the push plate 32 and the limit bin 3; a spring 322 is fixed between the push plate 32 and the limit bin 3, so that when the manhole cover is lifted up and tilted, the manhole cover will drive the push plate 32 to stop vertical movement, and the spring 322 fixed between the push plate 32 and the limit bin 3 will push the push plate 32 through the elastic release force, thereby achieving the purpose of limiting the manhole cover and preventing the manhole cover from being lifted up and tilted.

[0020] The bottom end of the motion guide rod 41 is fixedly connected to a fixed seat 42, and a clearance groove 43 is opened inside the motion guide rod 41, and the motion guide rod 41 slides inside the clearance groove 43; the fixed seat 42 fixed at the bottom end of the motion guide rod 41 is used to limit the initial height of the positioning plate 4, so that the fixed seat 42 will not contact the top of the manhole cover. When sewage overflows from the manhole cover, the manhole cover can contact the bottom end of the positioning plate 4, thereby achieving the purpose of driving the positioning plate 4 to move vertically through buoyancy, and the clearance groove 43 opened inside the motion guide rod 41 is used to guide the sliding of the positioning plate 4, so that the positioning plate 4 will not have unnecessary displacement when sliding.

[0021] The working principle and use process of the utility model are as follows: when there is a problem with the sewage pipeline, causing the sewage to lift up and tilt the manhole cover, the staff can place the mounting base 1 above the road so that the limit bin 3 is located above the manhole cover. At this time, the staff can fix the mounting base 1 above the road by means of bolts, etc., and then the staff can post a reminder on one side of the reminder plate 21 to achieve the purpose of reminding the moving vehicles. While reminding the vehicles, when the sewage lifts up the manhole cover again, the manhole cover will drive the push plate 32 to move vertically when it is tilted, so that the push plate 32 and the limit bin 3 are installed on the push plate 32 and the limit bin 3. The spring 322 between the bins 3 will push the push plate 32 to move through the force of elastic release, thereby achieving the purpose of limiting the manhole cover and preventing the manhole cover from tilting. When sewage overflows from the manhole cover, the sewage will contact the bottom of the positioning plate 4 and drive the positioning plate 4 to move vertically upward through buoyancy until the positioning plate 4 reaches a position close to the proximity switch 33. At this time, the proximity switch 33 will send a signal to the outside world through the signal transmission module installed inside the limit bin 3, so that the staff can quickly learn about the sewage overflow, which is convenient for the staff to repair the sewage pipeline.
