Embodiment Construction
[0029] Such as Figure 1 to Figure 15 As shown, the present invention includes a support frame 1, a garbage baffle 2, a flow limiting plate 3, a spring 5, an adjusting plate 6 and a rope 7, and the present invention will be described below in conjunction with the accompanying drawings.
[0030] Such as Figure 1 to Figure 4 As shown, the support frame 1 is a square hollow metal piece with two long sides and two short sides, which can be welded and fixed by four metal rods with a rectangular cross section, or can be cut by a wire to form a rectangular metal plate get. Such as Figure 6 As shown, a groove 11 is provided at the bottom of the support frame, and the length dimension of the groove is between the length dimension of the inner cavity of the support frame and the length dimension of the shape of the support frame; the width dimension of the groove is between the length dimension of the support frame Between the width dimension of the inner cavity and the width dimen...

A water draining well lid capable of adjusting the water displacement is used for solving the problem that the existing water draining well lids cannot drain water according to the water volume and comprises a supporting frame and a rubbish baffle plate. Water leaking holes are formed in the rubbish baffle plate, the mounting end of the rubbish baffle plate is in hinged connected with one short side of the supporting frame, and the free end of the rubbish baffle plate overlaps on the other short side of the supporting frame. A flow-restriction plate is in hinged connection with one side of the supporting frame, multiple springs are arranged between the free end of the flow-restriction plate and the corresponding side of the supporting frame, and under the function of the springs, the upper surface of the flow-restriction plate is in contacted with the bottom of the supporting frame in a matching mode. An adjusting plate is in hinged connection with the bottom of the rubbish baffle plate, and a torsion spring is arranged on a hinged shaft of the rubbish baffle plate and the adjusting plate. Under the function of the torsion spring, the upper surface of the adjusting plate is contacted with the bottom surface of the rubbish baffle plate, and the free end of the adjusting plate is connected with the free end of the rubbish baffle plate through a rope. The water draining well lid capable of adjusting water displacement can prevent rubbish from entering a sewer, and can realize the discharge of the rainwater according to the rainwater volume.
Description
technical field [0001] The invention relates to the technical field of drainage well covers, in particular to a drainage well cover which can prevent sundries from entering sewers and can discharge water according to the amount of rainwater. Background technique [0002] On city streets, manhole covers play an important role in dredging rainwater from the streets. Especially in the summer of our country, there is a lot of rain and a large amount of rainfall. If the precipitation on the streets is not removed in time, it will have a negative impact on the traffic in the city. Some of the existing drainage well covers are circular metal parts with round holes through which rainwater leaks. Due to the limited size of the round holes, the drainage efficiency is low; some are welded by several steel bars. The drainage well covers of this structure , although the rapid discharge of rainwater can be achieved, but garbage such as branches, leaves and plastic bags on the street can ...
