Description

Technical Field

[0001] The utility model belongs to the technical field of sewage manhole covers, and in particular relates to a safe sewage manhole cover with a self-luminous warning slogan. Background Art

[0002] With the popularization of sewage pipe networks, sewage wells can be seen everywhere in life. There are flammable gases in sewage wells. Minors may like to throw firecrackers into sewage wells when playing with them or others may like to throw them into sewage wells after smoking, and accidentally ignite the flammable gases in the wells, causing explosions. In serious cases, major safety accidents may occur. At present, sewage well covers are cast iron well covers, which only have raised patterns, sewage words and the name of the property unit. Especially at night when the light is weak, it is difficult to distinguish whether the well is a sewage well or a tap water gate well. At the same time, the existing sewage well covers cannot extinguish the open flames thrown into the wells in time. Minors or other personnel are unaware of the risks and throw open flames into the wells, causing explosions in the wells, which will lead to safety accidents and cause significant economic losses. Utility Model Content

[0003] In order to solve the above problems, the utility model discloses a safe sewage manhole cover with a luminous warning slogan. The cover has a luminous warning slogan, which serves as a warning to personnel around the clock and can extinguish open flames thrown into the well in time, thereby improving safety.

[0004] In order to achieve the above object, the technical solution of the utility model is as follows:

[0005] A safe sewage manhole cover with a luminous warning slogan, including a black manhole cover body, the front of the manhole cover body is a groove structure, the bottom of the groove is provided with a white slogan, the groove is filled with epoxy resin with white luminous powder, the manhole cover body is provided with a vent, the vent extends downward to form a hollow cylinder, the back of the manhole cover body is provided with a safety pipeline, the safety pipeline includes two U-shaped water traps, a filter-like short tube and a straight pipe, the upper end of one end of the U-shaped water trap is connected to the filter-like short tube, the filter-like short tube is connected to the hollow cylinder, and the other ends of the two U-shaped water traps are connected by a straight pipe.

[0006] As a supplement to the present invention, the epoxy resin surface is provided with tempered glass, and the surface of the tempered glass is lower than the upper surface of the groove.

[0007] As a supplement to the present invention, the filter-like short tube is connected to the hollow cylinder via structural adhesive.

[0008] As a supplement to the present invention, a plurality of air-permeable circular holes are provided on the surface of the filter-shaped short tube.

[0009] As a supplement to the present invention, the safety pipeline is made of PVC or PE.

[0010] The beneficial effects of the utility model are:

[0011] (1) Since a self-luminous white warning slogan is added to the ordinary manhole cover, in daily use, the white slogan and the black sewage manhole cover form a sharp contrast, which can give people a striking warning effect during the day. At night, the luminous slogan can also serve as a warning to people.

[0012] (2) There is water in the safety pipeline. If someone accidentally throws an open flame into the sewage well, the remaining water can extinguish the flame in time.

[0013] (3) The purpose of setting up a short filter-like pipe is to facilitate the exhaust of air inside the well and outside and balance the air pressure.

[0014] (4) The tempered glass on the warning text can improve the durability of the warning slogan when used on the road. At the same time, when the road cleaners clean the road, the dust on the tempered glass can be easily cleaned, ensuring the energy storage effect of the luminous powder during the day. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a top view of the manhole cover body described in the utility model.

[0016] Figure 2 This is a cross-sectional view of the groove described in the utility model.

[0017] Figure 3 This is a schematic diagram of the safety pipeline described in the utility model.

[0018] List of Figure Symbols:

[0019] 1. Manhole cover body, 2. Groove, 3. White slogan, 4. Epoxy resin, 5. Tempered glass, 6. Vent, 7. Hollow cylinder, 8. Safety pipe, 9. Filter-like short pipe, 10. U-shaped water trap, 11. Straight pipe. DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] As shown in the figure, a safe sewage manhole cover with a self-luminous warning slogan described in the utility model includes a manhole cover body 1, the front of the manhole cover body 1 is a groove structure, a white slogan 3 is provided at the bottom of the groove 2 (for example: there is flammable gas in the well, open flames are strictly prohibited), the groove 2 is filled with epoxy resin 4 with white luminous powder, a vent 6 is provided on the manhole cover body, the vent 6 extends downward 2-5cm to form a hollow cylinder 7, a safety pipeline 8 is provided on the back of the manhole cover body, and the safety pipeline 8 includes two U-shaped water traps 10, a filter-like short tube 9 and a straight tube 11, the filter-like short tube 9 is connected to the top of one end of the U-shaped water trap 10 (the filter-like short tube 9 can be regarded as a part of the U-shaped water trap), a plurality of breathable circular holes are provided on the surface of the filter-like short tube, the filter-like short tube 9 is connected to the hollow cylinder 7 by structural glue, and the other ends of the two U-shaped water traps 10 are connected by a straight tube 11.

[0022] At present, the sewage manhole cover is a cast iron manhole cover, which only has raised patterns, sewage words and the name of the property unit. Especially at night when the light is weak, it is difficult to distinguish whether the well is a sewage well or a tap water gate well. The utility model sets a white slogan 3 in the groove, which forms a sharp contrast with the black part of the sewage manhole cover. The warning slogan can be seen prominently during the day. At night, the luminous powder in the daytime absorbs energy under the light and can emit light at night. At night, people can also see the luminous warning slogan on the sewage manhole cover. In daily life, the slogan on the sewage manhole cover can improve people's safety awareness and let people understand the serious safety accidents that may be caused by throwing open flames into the well. If someone accidentally throws an open flame into the sewage well, the water in the U-shaped water trap of the sewage manhole cover can extinguish the open flame in time.

[0023] The purpose of providing the filter-like short pipe 9 is to facilitate exhaustion between the well and the outside and balance the air pressure.

[0024] In order to improve the durability of warning slogans on the road, the utility model is provided with tempered glass 5 on the surface of the epoxy resin 4. When the road cleaner cleans, the dust on the tempered glass on the road can be easily cleaned, thereby ensuring the energy storage effect of the luminous powder during the day. In addition, the surface height of the tempered glass 5 is ≤ the upper surface height of the groove 2.

[0025] The safety pipeline of the utility model is made of PVC or PE, and can also be made in one piece with the sewage manhole cover (cast iron material).

[0026] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
