Description

Technical Field

[0001] This utility model relates to a drain pipe sealing device, belonging to the field of drainage equipment technology. Background Technology

[0002] Urban drainage pipes and channels are essential infrastructure for modern cities and are the backbone of urban water pollution prevention, flood control, and drainage management. A sealing device is installed at the outlet of the drainage pipe, which has a sealing plate driven by an electric cylinder to seal the outlet of the drainage pipe.

[0003] Existing sealing devices have the following drawbacks:

[0004] Although the existing device can open and close the sealing plate using an electric cylinder, the electric cylinder in the sealing device is prone to failure because it is in a dark and humid environment for a long time and has not been used for a long time. This can cause the sealing plate to fail to open and close properly, affecting the normal use of drainage pipes in emergencies, such as when drainage pipes need to be opened in time during a rainstorm in the city. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in an emergency, how to ensure that the sealing plate can still be opened or closed even if the electric cylinder that drives the sealing plate to open or close malfunctions.

[0006] To address the above problems, the technical solution proposed by this utility model is as follows:

[0007] A drain pipe sealing device includes a mounting frame at the drain outlet of the drain pipe, a sealing plate mounted on the mounting frame, and an electric cylinder 1. It also includes an electric cylinder 2 disposed between the drain outlet and the mounting frame. The extension and retraction directions of the electric cylinder 1 and the electric cylinder 2 are axial directions of the drain pipe. When the extension rod 1 of the electric cylinder 1 extends or retracts, it can drive the sealing plate to seal or open the drain outlet. When the extension rod 2 of the electric cylinder 2 extends or retracts, it can move the mounting frame, the electric cylinder 1 mounted on the mounting frame, and the sealing plate, and cause the sealing plate to seal or open the drain outlet.

[0008] There are two electric cylinders, which are symmetrically installed on both sides of the drain outlet of the drain pipe.

[0009] The mounting frame is a U-shaped rectangular frame consisting of two columns and one beam. The two columns are fixedly connected to the telescopic rods of the two electric cylinders, forming a rectangular cavity that runs through both sides of the mounting frame with the beam. The sealing plate is located inside the rectangular cavity, and the electric cylinder is installed between the sealing plate and the beam.

[0010] It also includes an annular mounting base fixedly installed on the outer circumferential surface of the drain outlet of the drain pipe, and the electric cylinder is fixed on the mounting base.

[0011] The sealing plate has a protruding plug protruding into the drain pipe on the side facing the drain pipe. The outer peripheral surface of the plug protruding into the drain pipe can be close to the inner wall of the drain pipe. Beneficial effects

[0012] In an emergency, if the first electric cylinder malfunctions, the second electric cylinder can push the entire mounting bracket to open or block the discharge port. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0018] like Figure 1 , 2 As shown, a drain pipe sealing device includes a mounting frame 1 installed at the discharge port 701 of a drain pipe 7, a sealing plate 2 installed on the mounting frame 1, and an electric cylinder 3. It also includes an electric cylinder 4 positioned between the discharge port 701 and the mounting frame 1. The extension and retraction directions of the electric cylinders 3 and 4 are axial directions of the drain pipe 7. When the extension rod 301 of the electric cylinder 3 extends or retracts, it can drive the sealing plate 2 to seal or open the discharge port 701. When the extension and retraction of the extension rod 401 of the electric cylinder 4 extends or retracts, it can move the mounting frame 1, the electric cylinder 3, and the sealing plate 2 installed on the mounting frame 1, causing the sealing plate 2 to seal or open the discharge port 701. Thus, in an emergency, if the electric cylinder 3 malfunctions and cannot seal or open the discharge port 701 using the sealing plate 2, the electric cylinder 4 can perform the sealing or opening of the discharge port 701 using the sealing plate 2.

[0019] To ensure force balance, two electric cylinders 4 are provided, symmetrically installed on both sides of the discharge port 701 of the drain pipe 7. The mounting frame 1 is a U-shaped rectangular frame composed of two columns 101 and a beam 102. The two columns 101 are fixedly connected to the telescopic rods 2 of the two electric cylinders 4 respectively, forming a rectangular cavity 103 through both sides of the mounting frame 1 with the beam 102. The sealing plate 2 is located in the rectangular cavity 103, and the electric cylinder 3 is installed between the sealing plate 2 and the beam 102.

[0020] The aforementioned sealing device also includes an annular mounting base 5 fixedly installed on the outer periphery of the drain outlet 701 of the drain pipe, and the electric cylinder 4 is fixed on the mounting base 5 to make the installation of the electric cylinder 4 more stable.

[0021] Outside the drain pipe 7, there is a switch box 6 for controlling electric cylinder 3 and electric cylinder 4. Example 2

[0022] like Figure 3 As shown, it is a further improvement of the first embodiment. The side of the sealing plate 2 facing the drain pipe 7 has a plug platform 201 that protrudes into the drain pipe 7 and can be inserted into the drain pipe 7. The outer peripheral surface of the plug platform 201 inserted into the drain pipe 7 can be close to the inner wall of the drain pipe 7, so that the sealing plate 2 and the electric cylinder 3 can be more stable on the mounting bracket 1 in the sealing state, and it is also beneficial to the sealing of the drain pipe.

[0023] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the scope of protection covered by the present invention. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present invention.
