Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a temporary protection and warning device for a sewer outlet used in municipal engineering. Background Art

[0002] The sewer manhole covers on the road are an important part of municipal engineering. They are prone to collapse after long-term use, or may be washed away by heavy rain. Therefore, sewer manhole covers need regular maintenance and servicing to increase their service life. Maintenance takes a certain amount of time. Before the maintenance is completed, protective measures such as fencing are needed to enclose the sewer openings to alert vehicles or pedestrians and prevent accidents.

[0003] At present, when maintaining the manhole cover, four groups of fences are usually used to enclose the sewer opening so that the sewer opening is within the protection range of the fence, and warning signs or warning devices are placed. This temporary protection and warning measure is low-cost, economical and practical, but there are also some problems. The stability of the fence is relatively poor. When it is hit by an external impact, the position of the fence may shift or even fall. The deviation of the fence may cause the sewer opening to be out of the protection range of the fence. When the light is poor at night, accidents are prone to occur.

[0004] In response to the above-mentioned problems, one-piece fences have appeared on the market. The fences are rectangular or circular, with improved stability and are not easy to tip over. However, the one-piece fences occupy a relatively large space, and therefore require more space for transportation and storage. In addition, although the one-piece fences have improved stability, they may still shift in position when impacted by external factors, posing certain safety hazards. Utility Model Content

[0029] like Figure 1-Figure 6 As shown, a temporary protective warning device for a sewer outlet for municipal engineering includes two enclosures 100 and two folding plates 200. The two enclosures 100 and the two folding plates 200 form a rectangular structure. The two enclosures 100 are arranged opposite to each other, and the enclosures 100 and the folding plates 200 are hingedly connected.

[0030] The enclosure 100 includes a rectangular frame 101, and a plurality of protective rods 102 are evenly distributed in the frame 101. The protective rods 102 are vertically arranged. The frame 101 is also provided with a limit rod 103 arranged in the vertical direction. The bottom of the limit rod 103 is hinged to the bottom of the frame 101. The top of the frame 101 is provided with a groove that matches the limit rod 103. The limit rod 103 is inserted into the groove for easy hiding and fixing. The limit rod 103 includes a hollow cylinder 1031 and an extension rod 1032 slidably assembled in the hollow cylinder 1031. The side wall of 1031 is threadedly connected with a locking bolt 1033 for locking the extension rod 1032. The top of the extension rod 1032 is hinged with a connecting rod 1034. The extension rod 1032 is also provided with a locking pin 1035 for locking the connecting rod 1034. The connecting rod 1034 is provided with a pin hole (not shown) that matches the locking pin 1035. When the connecting rod 1034 needs to be rotated, the locking pin 1035 is pulled out, the connecting rod 1034 is rotated, and then the locking pin 1035 is inserted into the pin hole on the connecting rod 1034 to lock the connecting rod 1034. The locking pin 1035 can be a pin shaft with a thread or a spring pin shaft to prevent the locking pin 1035 from falling and being lost.

[0031] Two folding plates 200 , the folding plates 200 include a first baffle 201 and a second baffle 204 , a hinge shaft 202 is provided between the first baffle 201 and the second baffle 204 , the first baffle 201 and the second baffle 204 are both hinged to the hinge shaft 202 , and a warning device 203 is provided on the top of the hinge shaft 202 .

[0032] In this embodiment, the warning device 203 is a plastic tube, and a reflective strip is attached to the outer wall of the plastic tube. The plastic tube is sleeved on the hinge shaft 202 to facilitate the removal of the plastic tube. In other embodiments, the warning device 203 can also be a warning light.

[0033] like Figure 5 As shown, the distribution direction of the two enclosures 100 is defined as the front-to-back direction, and the two limit rods 103 are staggered along the front-to-back direction to divide the sewer opening 300 into three parts to block the sewer opening 300 and prevent pedestrians from falling into the sewer opening 300 in an accident.

[0034] Working principle: When in use, the device is unfolded to form a rectangle so that the device surrounds the sewer opening 300. Then the hollow cylinder 1031 is rotated to a horizontal position, the extension rod 1032 is stretched to adjust the length, and the extension rod 1032 is fixed by the locking bolt 1033 after adjustment; then the connecting rod 1034 is rotated to be perpendicular to the extension rod 1032, so that the connecting rod 1034 is inserted into the sewer opening 300, and the connecting rod 1034 is locked to limit the position of the device, so that the device will not be displaced when a slight collision or bump occurs, so as to prevent the sewer opening 300 from exceeding the protection range of the fence due to the displacement of the fence.

[0035] After use, the device can be folded and retracted for easy transportation and storage.

[0036] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
