Description

Technical Field

[0001] This utility model relates to the field of water accumulation alarm technology, and in particular to a water accumulation alarm device for urban underpasses. Background Technology

[0002] Urban underpasses can alleviate traffic congestion and improve citizens' travel conditions. However, due to their special structure and geographical location, urban underpasses are highly susceptible to natural factors such as rainfall, leading to frequent water accumulation, which can even affect urban traffic safety and citizens' travel safety in severe cases.

[0003] Existing water accumulation alarm devices are vertical cylindrical in shape and are equipped with liquid level sensors or other types of water accumulation detection sensors inside. These sensors monitor changes in water level or the state of water body. However, once the water has submerged the alarm device, the water depth cannot be directly determined, which greatly reduces its warning effect.

[0004] Based on this, this utility model designs a water accumulation alarm device for urban underpasses to solve the above problems. Utility Model Content

[0005] In view of the problems in the above or existing technologies, such as the alarm effect being greatly reduced after the water level exceeds the alarm level, and the inability to directly observe the water depth, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a water accumulation alarm device for urban underpasses.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: including an outer cylinder assembly and an inner cylinder assembly disposed inside the outer cylinder assembly;

[0008] An outer cylinder assembly includes an outer cylinder body, an upper floating ring is provided inside the outer cylinder body, a ring magnet is provided inside the upper floating ring, and a mesh plate is provided outside the outer cylinder body;

[0009] The inner cylinder assembly includes an inner cylinder body, with a lower floating ring and a limiting ring on the outside of the inner cylinder body, a pressure ring at the upper end of the inner cylinder body, a colored light alarm column inside the inner cylinder body, two inclined bottom grooves inside the inner cylinder body, each of the two inclined bottom grooves having an inclined bottom block, and multiple water inlets at the bottom of the inner cylinder body.

[0010] As a preferred embodiment of the water accumulation alarm device for urban underpasses according to this utility model, the outer cylinder assembly is provided with a chassis at its lower end, the upper floating ring is sleeved on the outer end of the inner cylinder body, and the lower floating ring is sleeved inside the outer cylinder body.

[0011] As a preferred embodiment of the water accumulation alarm device for urban underpasses according to this utility model, the inner cylinder body has four movable slots at its outer end, and the lower floating ring has four movable blocks inside, with the four movable blocks arranged inside the four movable slots.

[0012] As a preferred embodiment of the water accumulation alarm device for urban underpasses according to this utility model, the lower end of the colored light alarm column is provided with a float, and a buckle cylinder is provided below the float. All four moving blocks are connected to the buckle cylinder.

[0013] As a preferred embodiment of the water accumulation alarm device for urban underpasses according to this utility model, the colored light alarm column is provided with an electrical connection inside, the inner cylinder body is provided with a support rod, the upper part of the support rod is connected to the electrical connection, and the support rod is sleeved inside the colored light alarm column, the float and the buckle cylinder.

[0014] As a preferred embodiment of the water accumulation alarm device for urban underpasses according to this utility model, the lower end of the pressure ring is provided with four limiting rods, and a return spring is provided below each of the four limiting rods.

[0015] As a preferred embodiment of the water accumulation alarm device for urban underpasses according to this utility model, the lower end of the pressure ring is provided with four pressure rods, and all four pressure rods pass through the limiting ring.

[0016] The beneficial effects of this utility model on a water accumulation alarm device for urban underpasses are as follows: Water passes through the mesh plate and enters the outer cylinder assembly. The upper floating ring is buoyed and rises with the water level. When the rising upper floating ring reaches the position of the limiting ring, it is stopped by the limiting ring. The ring magnet inside the upper floating ring attracts the inclined bottom block inside the inclined bottom groove, causing the inclined bottom block to loosen its engagement with the color light alarm column. After the lower floating ring loses resistance, it will rise under the action of buoyancy. The upward-lifted color light alarm column will loosen its obstruction of the water inlet, allowing water to enter the inner cylinder body and assist the lower floating ring in pushing the color light alarm column, causing the color light alarm column to extend out of the inner cylinder body. The different heights of the exposed part indicate different brightness levels, which can be used to judge the water depth and improve the warning effect. Attached Figure Description

[0033] Specifically, the lower end of the outer cylinder assembly 1 is provided with a chassis 3, the upper floating ring 13 is sleeved on the outer end of the inner cylinder body 21, and the lower floating ring 22 is sleeved inside the outer cylinder body 11.

[0034] Furthermore, the chassis 3 is fixedly mounted on the lower end face of the outer cylinder assembly 1, the upper floating ring 13 is slidably sleeved on the outer end of the inner cylinder body 21, and the lower floating ring 22 is slidably sleeved inside the outer cylinder body 11.

[0035] Specifically, the outer end of the inner cylinder body 21 is provided with four moving slots 23, and the lower floating ring 22 is provided with four moving blocks 216, which are arranged inside the four moving slots 23.

[0036] Furthermore, four movable slots 23 are equidistantly opened at the lower side of the outer end of the inner cylinder body 21, and four movable blocks 216 are equidistantly fixed in the middle position inside the lower floating ring 22, and the four movable blocks 216 are slidably disposed inside the four movable slots 23.

[0037] Specifically, a float 29 is provided at the lower end of the colored light alarm column 27, and a buckle 210 is provided below the float 29. All four moving blocks 216 are connected to the buckle 210.

[0038] Furthermore, the float 29 is fixedly installed on the lower end face of the color light alarm column 27, the buckle 210 is fixedly installed on the lower end face of the float 29, and the four moving blocks 216 are fixedly installed at equal intervals at the middle position of the outer end of the buckle 210.

[0039] Specifically, the color light alarm column 27 is provided with an electrical connection 215 inside, the inner cylinder body 21 is provided with a support rod 28 inside, the upper part of the support rod 28 is connected to the electrical connection 215, and the support rod 28 is sleeved inside the color light alarm column 27, the float 29 and the buckle cylinder 210.

[0040] Furthermore, the inner top surface of the color light alarm column 27 is provided with an electrical contact 215, the inner bottom surface of the inner cylinder body 21 is fixedly provided with a support rod 28, and the upper end of the support rod 28 is provided with an embedded piece, which is inserted between the electrical contact 215. The color light alarm column 27, the float 29 and the buckle 210 are respectively slidably sleeved on the outer end surface of the support rod 28.

[0041] In use, the alarm device is fixed inside the channel via the chassis 3. When rainwater accumulates during rain, the water passes through the mesh plate 12 on the outer cylinder assembly 1 and enters the outer cylinder body 11. The floating ring 13 rises at the outer end of the inner cylinder assembly 2 due to the buoyancy of the water. A ring magnet 14 is installed inside the floating ring 13. The floating ring 13 continues to rise due to the influence of water until it is stopped by the limiting ring 24. At this time, the ring magnet 14 and the inclined bottom block 214 are aligned, and the ring magnet 14 attracts the inclined bottom block 214, causing the inclined bottom block 214 to retract into the inclined bottom groove 213. Then the inclined bottom block 214 is released. The alarm light column 27 is engaged, and the lower float ring 22 is not affected by resistance. The lower float ring 22 rises due to buoyancy. The lower float ring 22 drives the retaining cylinder 210 to rise via the moving block 216. The moving block 216 moves within the moving groove 23, allowing the lower float ring 22 to move stably upwards. The retaining cylinder 210 releases its obstruction of the water inlet 217, and water from inside the outer cylinder body 11 enters the inner cylinder body 21 through the water inlet 217. A float 29 is installed between the retaining cylinder 210 and the alarm light column 27. This float 29 also rises due to buoyancy. The cooperation between the cylinder 29 and the lower float ring 22 gives the color light alarm column 27 an upward force. When the color light alarm column 27 rises, the embedded piece above the support rod 28 will release and block the electrical contact 215, allowing the electrical contact 215 to be energized, causing the color light alarm column 27 to light up and sound an alarm. Moreover, affected by water depth, the deeper the water level, the greater the water pressure, and the more water enters the inner cylinder body 21 through the inlet 217, causing the color light alarm column 27 to float higher. When the water level drops, water is discharged from the inner cylinder body 21 and the outer cylinder body 11, and the color light alarm column 27 has no buoyancy. The support will descend, and the upper floating ring 13 will be positioned by the attraction between the ring magnet 14 and the inclined bottom block 214. When the color light alarm column 27 descends, its upper end will press against the pressure ring 25, causing the pressure ring 25 to drive the pressure rod 26 through the limit ring 24 to push the upper floating ring 13, causing the upper floating ring 13 to disengage from the magnetic attraction of the inclined bottom block 214 and move downward. The inclined bottom block 214 loses its magnetic attraction and slides out under the action of the inclined surface at the bottom of the inclined bottom groove 213, re-locking the color light alarm column 27. Meanwhile, the limit rod 211 below the pressure ring 25 is pushed by the reset spring 212, allowing the pressure ring 25 to reset.

[0042] In summary, the upper floating ring 13 rises with the water level due to buoyancy. As it rises, the upper floating ring 13 reaches the ring magnet 14 inside the limiting ring 24, which attracts the inclined bottom block 214 inside the inclined bottom groove 213. This causes the inclined bottom block 214 to release its engagement with the color light alarm column 27. At this point, the lower floating ring 22 moves upward without resistance, allowing the color light alarm column 27 to extend out of the inner cylinder body 21. The color light alarm column 27 will display different brightness levels at different heights to determine the water depth and improve the warning effect.

[0043] Example 2, refer to Figures 1 to 6This is the second embodiment of the present invention, which provides a water accumulation alarm device for urban underpasses;

[0044] Specifically, the lower end of the pressure ring 25 is provided with four limiting rods 211, and a return spring 212 is provided below each of the four limiting rods 211.

[0045] Furthermore, four limiting rods 211 are fixedly and equidistantly arranged on the inner ring of the lower end face of the pressure ring 25, and a return spring 212 is fixedly arranged on the lower end of each of the four limiting rods 211. The four return springs 212 are respectively embedded in the upper end face of the inner cylinder body 21.

[0046] Specifically, the lower end of the pressure ring 25 is provided with four pressure rods 26, and all four pressure rods 26 penetrate the limiting ring 24.

[0047] Furthermore, four pressure rods 26 are fixedly arranged at equal intervals on the outer ring of the pressure ring 25, and the four pressure rods 26 slide through the limiting ring 24 and are movably arranged above the floating ring 13.

[0048] When in use, the color light alarm column 27 descends and presses the pressure ring 25 above it, causing the pressure ring 25 to drive the pressure rod 26 to descend and press the upper floating ring 13. The magnetic connection between the inner ring magnet 14 and the inclined bottom block 214 of the upper floating ring 13 is released, allowing it to descend normally. The inclined bottom block 214 then re-clamps the color light alarm column 27, and the pressure ring 25 is reset by the push of the limit rod 211 by the reset spring 212, waiting for the next use.

[0049] In summary, the descending of the color light alarm column 27 presses against the pressure ring 25, causing the pressure rod 26 to descend and press against the upper floating ring 13, allowing the upper floating ring 13 to descend normally. Moreover, the pressure ring 25 is reset by the push of the limit rod 211 by the reset spring 212, waiting for the next use. This setting avoids the inclined bottom block 214 from affecting the normal descent of the color light alarm column 27.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
