Description

Technical Field

[0001] This utility model relates to the technical field of gravity flap doors, and in particular to a flap door clamp device for intelligent transformation of gravity flap doors. Background Technology

[0002] Urban drainage pipe networks generally use gravity flap gates to prevent backflow, but there are two major technical defects: (1) at low water levels, impurities accumulate and cause incomplete closure; (2) at high water levels, the water pressure is too high and it is difficult to open. Therefore, intelligent flap gate modification is urgently needed. Although the utility model patent with patent number CN207567933U proposes an electric flap gate solution, the existing intelligent flap gate modification solution has the following shortcomings: 1. It is necessary to dismantle the original flap gate structure and replace it with a brand new intelligent flap gate; 2. The construction period is long (water needs to be shut down for 3-5 days); 3. The modification cost is as high as 20,000-30,000 yuan / set. The technical problem of in-situ modification of gravity flap gates has not been solved, and the above-mentioned technical modification of millions of gravity flap gates across the country cannot be implemented.

[0003] How to achieve the transformation of existing gravity flap gates into intelligent flap gate devices without demolishing them, using non-destructive methods, is a key technical problem that urgently needs to be solved in the industry. This transformation is characterized by simple installation, short construction period (≤3 hours), and low cost (<5000 yuan / gate). Utility Model Content

[0004] The purpose of this utility model is to provide a door clamping device for intelligent transformation of gravity door flaps. Without removing the original gravity door flap, this device is added to the original gravity door flap. It adopts a non-destructive installation structure and a non-intrusive linkage control mechanism to achieve quick and simple installation and low-cost intelligent transformation of gravity door flaps.

[0005] According to one aspect of this utility model, a door clamping device for intelligent transformation of gravity door flapping is provided, including a robotic arm, an intelligent control module, and a door clamping module. The door clamping module includes a vertical rod, a horizontal rod, a movable clamping rod, a hinge, an elastic pressure block, and a steel rope hook. The intelligent control module is signal-connected to the robotic arm. One end of the vertical rod is fixedly installed on the dam wall, and the other end is fixedly installed on the door hinge of the gravity door flapping seat. One end of the horizontal rod is vertically installed in the middle of the vertical rod, and the other end is fixedly connected to one end of the robotic arm. The movable clamping rod is located below the horizontal rod, with one end installed on the vertical rod via a hinge, and the other end fixedly connected to the other end of the robotic arm. The elastic pressure block is located between the gravity door flapping cover and the movable clamping rod, with one side installed on the movable clamping rod and the other side abutting against the gravity door flapping cover. One end of the steel rope hook is fixedly connected to the movable clamping rod, and the other end is fixedly connected to the handle of the gravity door flapping cover.

[0006] In some embodiments, the present invention also includes a water level monitoring module, which is installed on the inner wall of the drainage pipe and is connected to the intelligent control module via signal.

[0007] In some implementations, the water level monitoring module is a water level gauge.

[0008] In some embodiments, the robotic arm is a pneumatic robotic arm, which includes a cylinder mounting base, a cylinder, and a rotating shaft. The cylinder mounting base is fixedly mounted on the other end of the crossbar, and the cylinder is connected to the cylinder mounting base through the rotating shaft. The cylinder is provided with a piston rod, the front end of which is hinged to the other end of the movable clamping rod.

[0009] In some embodiments, the piston rod has a telescopic range of 100-2000 mm, and the vertical rotation angle of the rotating shaft has a range of 0-180°.

[0010] In some implementations, the intelligent control module includes a water level signal acquisition unit, a control logic unit, and a drive output unit connected in sequence by circuits. The water level signal acquisition unit is connected to the water level monitoring module, and the drive output unit is connected to the cylinder.

[0011] In some implementations, the hinge is a self-lubricating hinge with a rotation angle range of 0-180°.

[0012] In some embodiments, the flapping gate clamp module also includes pipe clamps, wall clamps, and right-angle connectors. One end of the vertical rod is fixedly installed on the dam wall by the wall clamp, and the other end is fixedly installed above the door hinge of the gravity flapping gate seat by the pipe clamp. One end of the horizontal rod is vertically installed in the middle of the vertical rod by the right-angle connector.

[0013] The beneficial effects of this utility model are: (1) Non-destructive installation structure: This utility model achieves double fixation of the vertical rod through pipe clamps and wall clamps, ensuring the stability of the device, without destroying the original gravity door seat installation structure, and realizing non-destructive installation;

[0014] (2) Non-intrusive linkage control mechanism: This utility model sets a movable clamping rod and an elastic pressure block to contact the flapping door cover, and provides a steel rope hook to connect the flapping door cover handle. Without changing the original working structure of the gravity flapping door cover, the movable clamping rod and the flapping door cover are linked. At the same time, the pneumatic mechanical arm drives the movable clamping rod to achieve linkage control, so as to realize the precise opening and closing of the flapping door cover.

[0015] (3) The present invention can automatically compensate for the deformation of the flap cover by means of the elastic pressure block at the end of the movable clamping rod, so as to ensure the sealing effect of the flap cover on the pipe opening;

[0016] (4) Compared with the existing intelligent door flapping modification method, this utility model achieves a 76% reduction in installation time, a 67% reduction in modification cost, an improvement in sealing performance to 99.2%, and compatibility with more than 95% of existing gravity door flapping models.
