Description

Technical Field

[0001] The present application relates to the field of monitoring wells, and in particular to a protective device for desilting inspection wells. Background Art

[0002] Inspection wells are a key component of urban infrastructure and bear the important responsibility of maintaining the safe operation of underground pipeline systems. They are usually set up on the road to facilitate maintenance personnel to enter the well to perform daily maintenance and emergency repairs on various pipelines. Inspection wells not only improve the efficiency of maintenance work, but also ensure the safety and smoothness of road traffic. At the same time, inspection wells also have drainage functions, which can timely drain road water and prevent floods.

[0003] At present, in the desilting and inspection projects of urban municipal pipe networks, the protective devices for inspection wells usually adopt mobile iron horses, which are set up around the inspection wells and enclose the inspection wells to ensure the safety of workers, vehicles and pedestrians. When working at night, it is also necessary to equip the mobile iron horses with warning flashing lights to provide night protection warnings to prevent vehicles and pedestrians from colliding and causing the mobile iron horses to be moved.

[0004] However, the mobile iron horse has relatively poor stability and is easy to move. In addition, some large moving objects can still pass through the mobile iron horse and enter the inspection well. The protective effect is relatively poor and there is room for improvement. Utility Model Content

[0005] In order to improve the problems of low stability and poor protective effect of protective devices in related technologies, the present application provides a protective device for dredging inspection wells.

[0006] The present application provides a protective device for dredging inspection wells, which adopts the following technical solutions:

[0007] A protective device for a dredging inspection well comprises an upper base frame, a lower base frame for embedding in the well mouth of the inspection well is fixed on the lower side of the upper base frame, the lower base frame is a circular structure, and a first protective net is also fixed on the upper side of the lower base frame.

[0008] By adopting the above technical solution, in actual use, the lower base frame is embedded in the wellhead of the inspection well. At this time, the first protective net will cover the wellhead of the inspection well, which helps to ensure the stability of the protective device and reduce the occurrence of large objects entering the inspection well, thereby improving the protective efficiency of the protective device and improving the safety of workers during operations.

[0009] Preferably, a warning component is also provided on the upper base frame.

[0010] By adopting the above technical solution, the warning component warns oncoming vehicles and pedestrians, thereby reducing the occurrence of oncoming vehicles and pedestrians colliding with the protective device.

[0011] Preferably, the warning component comprises a warning stripe rod, and a plurality of the warning stripe rods are evenly spaced around the axis of the lower base frame, the lower end of each of the warning stripe rods is connected to the upper base frame, and the other ends of all the warning stripe rods are upward and overlapped with each other.

[0012] By adopting the above technical solution, a plurality of warning stripe rods arranged upwards can warn passing vehicles and pedestrians, further reducing the occurrence of passing vehicles and pedestrians colliding with the protective device.

[0013] Preferably, a hinged ear is fixed at the edge of the upper base frame, a latch is inserted through the hinged ear, the latch partially penetrates the lower end of the warning stripe rod, the warning stripe rod is hinged to the hinged ear through the latch, and both the hinged ear and the latch are arranged corresponding to the warning stripe rod;

The lower base frame can be lowered so that the guide frame falls down and lands on the load-bearing plate; the lower base frame can also be raised and rotated so that the guide frame falls on the support plate. This facilitates the lifting and lowering of the lower base frame and the conversion of the lower base frame between the working state and the idle state.

[0020] On the other hand, when the staff enters the inspection well, they can place the protective device next to the inspection well and enter the inspection well; then, they can pull the protective device to the upper side of the inspection well and rotate the lower frame so that the guide frame enters the guide groove and the lower frame enters the inspection well mouth. When the staff exits the inspection well, they lift the lower frame from the inspection well; when the guide frame reaches the support plate, they rotate the lower frame so that the guide frame is placed on the support plate; at this time, the staff can push the protective device away from the inspection well. This improves the convenience of using the protective device.

[0021] Preferably, the fixing member is a locking bolt, the locking bolt is threadedly connected to the lower base frame, and the end of the locking bolt is pressed against the side wall of the lifting groove.

[0022] By adopting the above technical solution, the locking bolt is tightened so that the end of the locking bolt is pressed against the side wall of the lifting groove, thereby realizing a detachable connection between the lower base frame and the upper base frame and helping to ensure the stability of the connection between the lower base frame and the upper base frame.
