Description

Technical Field

[0001] This utility model belongs to the field of manhole dredging construction, and in particular relates to an integrated device for manhole dredging and protection in drainage pipe networks. Background Technology

[0002] Over long-term use, municipal pipelines frequently experience silt and debris accumulation, as well as aging and damage, necessitating regular dredging and repair work. During dredging operations, manhole openings need to be protected to ensure the safety of workers and pedestrians. Traditional protective methods often involve simple fences or covers, which cannot fully cover the manhole openings during high-pressure water jet cleaning of pipelines and manholes, making it difficult to guarantee the safety of workers and pedestrians around the manholes. Currently, some simple support structures are used for protection, but these generally have narrow coverage and poor structural stability. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an integrated device for dredging and protecting drainage pipe network inspection wells.

[0004] This invention is achieved through the following technical solution:

[0005] An integrated device for dredging and protecting drainage pipe network inspection wells includes two symmetrical protective frames. A long rod is fixedly connected between the middle of the two short frames of the secondary protective frames. Several short rods are vertically connected between the long rod and the inner long frame of the secondary protective frame. Several inverted U-shaped buckles are welded to the side of the secondary protective frame near the inspection well. The device also includes a main protective frame. The two long frames of the main protective frame are respectively engaged with the inverted U-shaped buckles on both sides. The long frame of the main protective frame consists of a stationary rod and a sliding rod that are slidably connected together. Each stationary rod and sliding rod has a corresponding adjustment hole, with threaded bolts connected to the adjustment holes. Support rods are vertically fixed between the two stationary rods and between the two sliding rods. Stop rods are fixed downwards at both ends of the bottom surface of the support rods. A fixed shaft is fixed between the two sliding rods, and a pulley is rotatably connected to the fixed shaft. The pulley is located between the stop rods on the left and right sides.

[0006] Preferably, the inverted U-shaped buckle is an elastic buckle.

[0007] Preferably, two inverted U-shaped buckles are welded onto the secondary protective frame.

[0008] Preferably, the inner top surface of the inverted U-shaped buckle is flush with the top surface of the secondary protective frame.

[0009] Preferably, the thickness of the main protective frame and the thickness of the secondary protective frame are equal.

[0010] The protective device of this invention has a large coverage area. The three parts are connected as a whole, which is simple to assemble and has a stable structure, ensuring the safety of workers and pedestrians in the surrounding area. In addition, the device of this invention can avoid the location of the manhole cover, so that the protected area is not affected by the manhole cover, further ensuring safety. The device of this invention can also adjust its length according to the size of the manhole opening, and can be applied to the dredging work of manholes of different diameters, making it highly versatile.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0018] This embodiment includes two symmetrical protective frames 1, each a rectangular frame. A long rod 2 is fixedly connected between the middle of the two short side frames of the secondary protective frame 1, dividing the secondary protective frame 1 into two parts. The part furthest from the manhole opening allows a manhole cover to pass through; that is, the gap between the long rod 2 and the outer long side frame of the secondary protective frame 1 allows the manhole cover to pass through. Here, "outer side" refers to the side furthest from the manhole opening. Several short rods 3 are vertically connected between the long rod 2 and the inner long side frame of the secondary protective frame 1. Since the inner long side frame is above the manhole opening, the short rods 3 provide further protection, preventing personnel or large objects from falling through the gap between the long rod 2 and the inner long side frame. The number of short rods 3 can be determined according to specific circumstances. Several inverted U-shaped clips 4 are welded to the side of the secondary protective frame 1 near the manhole. The openings of the inverted U-shaped clips 4 face downwards and are used to engage with the main protective frame 5. Preferably, two inverted U-shaped clips 4 are welded to each secondary protective frame 1.

[0019] This embodiment also includes a main protective frame 5, which is also a rectangular frame. The lengths of both the main protective frame 5 and the aforementioned secondary protective frame 1 are greater than the wellhead diameter, meaning they can both cover the wellhead. The thickness of the main protective frame 5 is equal to the thickness of the secondary protective frame 1. The main protective frame 5 is located between the two secondary protective frames 1. The two long side frames of the main protective frame 5 are respectively engaged with the inverted U-shaped buckles 4 on both sides of the secondary protective frame 1. The width of the two long side frames of the main protective frame 5 is equal to the inner width of the inverted U-shaped buckles 4, allowing them to fit snugly into the inverted U-shaped buckles 4. To make the connection between the main protective frame 5 and the secondary protective frame 1 tighter, the inverted U-shaped buckles 4 are preferably elastic buckles, which can tightly engage the main protective frame 5 and the secondary protective frame 1 together. After engagement, the inner top surface of the inverted U-shaped buckle 4 is flush with the top surface of the secondary protective frame 1.

[0020] The main protective frame 5 is length-adjustable to accommodate manholes of different diameters. Specifically, the long side frames on both sides of the main protective frame 5 consist of stationary rods 6 and sliding rods 7 that are slidably connected together. The sliding rods 7 can slide left and right within the stationary rods 6 to adjust the overall length of the main protective frame 5. Each stationary rod 6 and sliding rod 7 has a corresponding adjustment hole 8. Bolts 9 are threaded into the adjustment holes 8 and pass downwards through them to securely connect the two rods, fixing the overall length of the main protective frame 5. Support rods 10 are vertically fixed between the two stationary rods 6 and between the two sliding rods 7. Stop rods 11 are fixed downwards at both ends of the bottom surface of the support rods 10. The stop rods 11 abut against the inner wall of the manhole. The two stop rods 11 on the left and two on the right abut against the left and right sides of the inner wall of the manhole, respectively, preventing the main protective frame 5 from moving left or right and ensuring safety.

[0021] A fixed shaft 12 is fixed between the two sliding rods 7, perpendicular to the sliding rods 7. A pulley 13 is rotatably connected to the fixed shaft 12, located between the two sliding rods 7. The pulley 13 can rotate around the fixed shaft 12 and is positioned between the left and right stop bars 11. The pulley 13 is used to release the pump pipe of the sewage suction truck or the cable of the cleaning equipment downwards to facilitate operations inside the well.

[0022] During construction, after lifting the manhole cover, first place the main protective frame 5 in the middle position above the manhole opening. The main protective frame 5 covers the middle of the manhole opening, and both side stops 11 are located inside the manhole. Make the stop 11 on the side of the stationary rod 6 press tightly against the manhole wall. Then pull the sliding rod 7 so that the stop 11 on the side of the sliding rod 7 presses tightly against the manhole wall on the other side. At this time, screw the bolts 9 into the adjustment holes 8 of the stationary rod 6 and the sliding rod 7 to fix the stationary rod 6 and the sliding rod 7. Then place the secondary protective frames 1 on both sides of the main protective frame 5. When placing them, the side of the secondary protective frame 1 with the inverted U-shaped buckle 4 should be hooked downward to the long frame of the main protective frame 5, and the secondary protective frame 1 and the main protective frame 5 should be hooked together. The secondary protective frames 1 on both sides can completely cover the manhole opening and the surrounding area. The side of the secondary protective frame 1 with the short rod 3 is located on the manhole side. When the secondary protective frame 1 on the manhole cover side is placed downward, the lifted manhole cover can pass through the gap between the long rod 2 and the outer long frame of the secondary protective frame 1. After assembly, the two connected protective frames 1 and the main protective frame 5 can completely cover the wellhead, with the excess portion resting on the ground around the wellhead. Once the device of this invention is installed and fixed, cleaning or maintenance equipment can be placed next to the wellhead, and the pump pipe or cable can be lowered from the pulley 13. The rotation of the pulley 13 prevents damage to the pump pipe or cable during lowering, while also improving lowering efficiency, making it easy to retrieve and lower, and thus improving construction efficiency.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
