Description

Technical Field

[0001] This utility model relates to a rainwater well cover lifting and retaining device. Background Technology

[0002] When cities experience heavy rainfall or torrential downpours, the drainage capacity of stormwater pipe networks is often insufficient to cope with the large amount of rainwater that accumulates in a short period of time, easily leading to urban flooding. To accelerate the drainage of water from the roads, municipal workers usually take measures such as temporarily opening storm drain covers—by increasing the flow area of ​​the drainage outlets, improving the efficiency of water discharge into the stormwater pipe network, and alleviating the flooding situation.

[0003] Currently, the procedure for temporarily opening storm drain covers is as follows: after the staff lifts the cover upwards at a certain angle, they use simple supports such as wooden sticks, bricks, and stones to place between the cover and the edge of the well opening to maintain the opening of the cover. In some scenarios, the cover is also removed and placed on the roadside, but this method poses serious safety hazards such as pedestrians falling or vehicles getting stuck. Therefore, in most scenarios, it is preferred to keep the cover half open.

[0004] However, existing technical solutions have significant drawbacks: Poor support stability. The contact between simple supports and manhole covers / openings is mostly point or line contact, resulting in uneven distribution of support force. Under the impact of strong water flow (such as the reverse thrust when water flows into the manhole), the supports are very easy to fall off or shift, causing the manhole cover to close again, interrupting the drainage process, and failing to meet the needs of emergency response to large-scale urban flooding.

[0005] Therefore, there is an urgent need for a technical solution that can stably maintain the temporary opening of rainwater well covers to solve the problems of unstable support, high safety risks, and low operational efficiency in existing technologies, and improve the effectiveness and safety of emergency response to urban flooding.

[0028] like Figures 1-7As shown, this embodiment provides a rainwater well cover lifting and holding device, including a tripod 1, a suspension rope 2 fixedly connected to the top middle of the tripod, and a hook 3 connected to the bottom end of the suspension rope; The tripod includes three support rods, each of which is composed of a fixed rod 4 and a movable rod 5 that are fixedly connected to each other. Each movable rod is connected to a hook 7 by a pull rope 6.

[0029] In this embodiment of the utility model, a base 8 is provided on the top of the tripod, and the top ends of the fixed rods are all hinged to the bottom of the base. A traction assembly is provided between two adjacent fixed rods. Each traction assembly includes a fixed ring 9 fixed on the fixed rod. Each traction assembly also includes a traction rod 10. One end of each traction rod is fixed with a connecting ring 11, and the other end is fixed with a hook 12. The connecting ring is connected in series with one of the fixed rings in the two adjacent fixed rods, and the hook is hooked on the other fixed ring in the two adjacent fixed rods.

[0030] In this embodiment of the utility model, a fixed pulley 13 is installed at the bottom center of the base, a rope fixing component is provided on the side of the fixed pulley, and the top of the suspension rope is wound around the fixed pulley and then connected to the rope fixing component.

[0031] In this embodiment of the utility model, the rope fixing assembly includes a fixing seat 14 fixed on the bottom surface of the base. The fixing seat is provided with two mounting through holes, and a U-shaped screw 15 is connected to the two mounting through holes. The top of the suspension rope is clamped between the U-shaped screw and the fixing seat, and the two external threads of the U-shaped screw are respectively locked by a wing nut 16.

[0032] In this embodiment of the invention, a warning light 17 is installed at the center of the top of the base. A rechargeable battery is provided inside the base to power the warning light.

[0033] In this embodiment of the utility model, the top of each movable rod is provided with a socket 18 for inserting the bottom of the fixed rod from top to bottom. The top of the movable rod and the bottom of the fixed rod are fastened together by a wing bolt 19 and a wing nut. The movable rod and the fixed rod can be easily disassembled and assembled.

[0034] In this embodiment of the utility model, the other end of the pull rope is connected to a rain grate claw 20, which is hinged to the middle of the movable frame. A ground-contact claw 21 is hinged to the bottom of the movable frame, and the bottom of the ground-contact claw is serrated. There are two hinge methods: The first type: The hinge shaft between the rain grate claw and the movable rod, and the hinge shaft between the ground contact claw and the movable rod, are both made of wing bolts, and each wing bolt is screwed with a wing nut; an L-shaped upper support rod 22 is also hinged in the middle of the rain grate claw, and multiple fixed upper support parts 23 are vertically evenly distributed below the rain grate claw on the movable rod, with the support notch 24 of the upper support parts facing upward, and the bottom end of the upper support rod is embedded for support; an L-shaped lower support rod 25 is also hinged in the middle front part of the ground contact claw, and multiple fixed lower support parts 26 are vertically evenly distributed above the ground contact claw on the movable rod, with the support notch of the lower support parts facing downward, and the top end of the lower support rod is embedded for support. By tightening and loosening the hinge shaft with a butterfly bolt, the rain grate claws and ground contact claws can be adjusted to a suitable swing angle and locked. The auxiliary support of the upper and lower support rods can enhance the support stability of the rain grate claws and ground contact claws.

[0035] The second method involves connecting the rain grate claws and ground contact claws to the movable frame via an angle adjuster 27. The fixed end 28 of the angle adjuster is screwed securely to the movable frame, and the rain grate claws and ground contact claws are screwed securely to the rotating end 29 of their respective angle adjusters. The angle adjuster allows direct adjustment of the rain grate claws and ground contact claws to a suitable swing angle and locking them in place. The angle adjuster is existing technology and will not be described in detail here.

[0037] Operators can choose between tapered support feet and surface support blocks as needed.

[0038] A method for operating a rainwater well cover lifting retainer includes the following steps: S1: Transport the rainwater well cover lifting retainer to the drainage site; S2: Place the rainwater well cover lifting retainer at the position of the rainwater well cover 32 to be opened, and unfold the tripod. After unfolding, use the hook of the pull rod to pull and connect the two adjacent fixed rods to limit the excessive extension of the tripod. S3: Loosen the wing nut of the rope fixing component to make it easier to lower the bottom end of the suspension rope so that the hook at the bottom end of the suspension rope can be hooked on the hanging opening on the rainwater well cover. Then the operator can lift the rainwater well cover upwards. S4: When the rainwater well cover is opened to a certain degree, the suspension rope is pulled to make it taut, and the wing nut of the rope fixing component is tightened to fix the top of the taut suspension rope to the rope fixing component. Under the suspension of the suspension rope, the rainwater well cover maintains a fixed opening for drainage. S5: During drainage, the warning light will be activated to provide visual warning.

[0039] This rainwater well cover lifting retainer can also be used to open rainwater grates. During operation, any movable rod is removed from the fixed rod, and the angles of the rainwater grate claw and the ground contact claw are adjusted by swinging. Then, the hook is hung forward and downward on the rainwater grate grid. The bottom end of the movable rod is then supported on the ground behind and next to the rainwater grate. At this time, the ground contact claw also touches the ground backward to provide additional support. Finally, the operator holds the top of the movable rod and pulls it backward to open the rainwater grate.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments.
