Description

Technical Field

[0001] This utility model relates to the field of municipal engineering tools technology, specifically an auxiliary opening device for rainwater well covers. Background Technology

[0002] In urban drainage systems, storm drain covers are important facilities for ensuring smooth drainage and maintaining public safety. They are widely distributed in urban roads, sidewalks, residential areas, and other areas. With the continuous expansion of urban scale and the continuous improvement of infrastructure, the number of storm drain covers is increasing year by year.

[0003] In municipal road construction projects, water accumulation often occurs at storm drain inlets. The reasons for this accumulation include large water volumes in a short period of time, blockage of the inlets by debris, and the drainage capacity being affected by the grate. To solve this problem, it is necessary to consider opening the storm drain grate to increase the water flow. However, if the grate is fully opened without warning signs, it will pose a safety hazard to pedestrians and vehicles. Therefore, those skilled in the art have provided a storm drain cover auxiliary opening device to solve the problems mentioned in the background art. Utility Model Content

[0008] As a further improvement of this utility model: a fixing steel plate is connected to the back of the second spiral sleeve, and two sets of positioning holes are opened inside the fixing steel plate.

[0009] As a further improvement of this utility model: the front of the fixed steel plate is connected to two reinforcing seats, and the two reinforcing seats are respectively connected to the left and right sides of the main support arm on their sides.

[0010] As a further improvement of this utility model: a protective pad is connected to the front of the auxiliary support arm, and the outer surface of the protective pad is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This rainwater well cover auxiliary opening device allows for the direct placement of warning cones via a set road cone support arm, eliminating the need for additional carrying or separate deployment of warning equipment. This reduces preparation time before operation and ensures precise alignment between the warning area and the work point, lowering the risk of pedestrians and vehicles accidentally entering the area. The main support arm and auxiliary support arm are then hinged together, allowing workers to easily adjust the tilt angle of the auxiliary support arm, thereby facilitating the adjustment of the well cover's opening angle.

[0014] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Please see Figures 1-5 In this embodiment of the utility model, a rainwater well cover auxiliary opening device includes a main support arm 1. The top end of the main support arm 1 is hinged to a first connecting post 2. One end of the first connecting post 2 is connected to an auxiliary support arm 3. A first loop sleeve 4 is sleeved on the outer surface of the main support arm 1. A second connecting post 5 is connected to the left side of the first loop sleeve 4. A traffic cone support arm 6 is hinged to the left end of the second connecting post 5. A first threaded hole 7 is opened inside the first loop sleeve 4. A first threaded post 8 is threaded inside the first threaded hole 7. One end of the first threaded post 8 is connected to a first tightening plate 9. A first handle 10 is connected inside the first threaded post 8. By sliding the first loop sleeve 4 up and down on the outside of the main support arm 1, the second connecting post 5 and the traffic cone support arm 6 can be driven to move up and down. This allows the staff to easily adjust the specific height of the traffic cone support arm 6 according to the actual situation.

[0017] The main support arm 1 is made of strip square steel. The outer surface of the main support arm 1 is coated with a corrosion-resistant coating. A second loop sleeve 11 is fitted on the outer surface of the main support arm 1. The second loop sleeve 11 has a second threaded hole 12 inside. A second threaded post 13 is threaded into the second threaded hole 12. One end of the second threaded post 13 is connected to a second tightening plate 14. A second handle 15 is connected inside the second threaded post 13. A fixing steel plate 16 is connected to the back of the second loop sleeve 11. The fixing steel plate 16 has two sets of positioning holes 17 inside. The corrosion-resistant coating on the outer surface of the main support arm 1 can resist the corrosion of acid and alkali substances in rainwater and sewage, extending the service life of the device. The second threaded post 13 and the second tightening plate 14 can be used to fasten the second loop sleeve 11 to the main support arm 1. The fixing steel plate 16 and the positioning holes 17 can be used to facilitate the workers to fix the device to the well wall.

[0018] The front of the fixed steel plate 16 is connected to two reinforcing seats 18. The two reinforcing seats 18 are connected to the left and right sides of the main support arm 1 on their respective sides. The front of the auxiliary support arm 3 is connected to a protective pad 19. The outer surface of the protective pad 19 is provided with anti-slip texture. The reinforcing seats 18 can be used to reinforce the second loop sleeve 11, so that the second loop sleeve 11 can be more firmly connected to the fixed steel plate 16. The protective pad 19 at the front end of the auxiliary support arm 3 not only enhances the friction during operation through anti-slip texture, but also avoids direct hard contact between the device and the manhole cover, reducing scratch damage to the surface of the manhole cover.

[0019] The working principle of this utility model is as follows: When using this device, the operator first uses the positioning hole 17 to fix the fixing steel plate 16 to the well wall. Then, the operator uses the second threaded column 13 to drive the second tightening plate 14 to fix the main support arm 1. At this time, the operator uses the first loop sleeve 4 to drive the second connecting column 5 and the road cone support arm 6 to move up and down, thereby adjusting the height of the road cone support arm 6. After the height of the road cone support arm 6 is adjusted, the operator uses the first threaded column 8 and the first tightening plate 9 to fix the first loop sleeve 4 to the outside of the main support arm 1. After all is fixed, the operator adjusts the opening angle of the auxiliary support arm 3 by rotating the hinge, and makes the auxiliary support arm 3 contact the bottom surface of the well cover. In this way, the opening angle of the well cover can be adjusted.
