[0020] Embodiment: A municipal drainage pipe maintenance device

[0021] like Figure 1-5 As shown, a municipal drainage pipe maintenance device, the specific structure of which includes:

[0022] Two symmetrically arranged support plates 1 are provided, and an airbag 2 is fixedly installed between the two support plates 1. An air intake connecting pipe 3 is fixedly installed on one side of one of the support plates 1, and the inner end of the air intake connecting pipe 3 is communicated with the interior of the airbag 2. A support component is provided on the outer side of the support plate 1.

[0023] The support assembly includes a first support rod 4, and a plurality of evenly distributed first support rods 4 are fixedly installed at the outer edge of the support plate 1, and the upper ends of the first support rods 4 are hingedly installed with second support rods 5, and the movable ends of the second support rods 5 are rotatably installed with rollers 6. The first support rods 4 are respectively connected to the corresponding second support rods 5 through springs 7, and the angle between the first support rods 4 and the second support rods 5 on one side of the spring 7 is an obtuse angle. When this structural design is used, the second support rods 5 are in an outwardly extended state under the action of the elastic force of the spring 7, and the rollers 6 can be in contact with the inner wall of the pipe when used, thereby improving the flexibility of the device when moving in the drainage pipe. Under the mutual cooperation of the first support rods 4, the second support rods 5, and the springs 7, the device can be supported in multiple directions. Since the first support rods 4 and the second support rods 5 are hingedly connected, when used in a drainage pipe with a smaller inner diameter, the extension range of the second support rods 5 can be reduced by pressing the second support rods 5 to the inner side of the support plate 1, thereby adapting to drainage pipes with different inner diameters.

[0024] A connecting plate 8 is fixedly installed on one side of the first support rod 4, one end of the spring 7 is fixedly connected to the corresponding connecting plate 8, and the other end of the spring 7 is fixedly connected to one side of the corresponding second support rod 5. When this structural design is in use, the connecting plate 8 is used to install the spring 7, and the spring 7 can support the second support rod 5 connected thereto through the elastic force of the spring 7, so that the second support rod 5 can be turned outward to maintain the opening effect.

[0025] The outer end of the air intake connecting pipe 3 is integrally fixed with a threaded joint. This structural design makes it easy for the user to connect the high-pressure air pipe to the air intake connecting pipe 3, thereby ensuring that the airbag 2 is inflated.

[0026] The movable end of the second support rod 5 is provided with a wheel groove 9, and the rollers 6 are respectively mounted with bearings in the wheel grooves 9. This structural design can facilitate the installation of the rollers 6.

[0027] The two support plates 1 are fixedly connected by a connecting rod 10, and the two ends of the connecting rod 10 are respectively fixedly connected to the opposite side of the support plate 1. The airbag 2 is an annular structure, and the airbag 2 is sleeved outside the connecting rod 10, and the two sides of the airbag 2 are respectively fixedly connected to the opposite side of the support plate 1. The connecting rod 10 can improve the stability of the two support plates 1 when in use. The two support plates 1 are fixed by the connecting rod 10, which can ensure that the distance between the two support plates 1 is fixed. When the airbag 2 is inflated, as the volume of the airbag 2 increases, the outer periphery of the airbag 2 can contact the inner wall of the drain pipe to achieve the blocking of the drain pipe.

[0028] Working principle:

[0029] When in use, the user first extends the device into the drain pipe, and then moves the device in the drain pipe through the roller 6 to move the device to the position that needs maintenance in the drain pipe, and then inflates the air bag 2 through the air intake connecting pipe 3. The inflation device can use the electric air pump commonly used in the prior art to expand the air bag 2 to support the inner wall of the drain pipe to prevent the drain pipe from collapsing. Then the maintenance personnel can enter the drain pipe to perform maintenance work. After the maintenance is completed, the user discharges the gas in the air bag 2 through the air intake connecting pipe 3, and then the device can be taken out from the drain pipe, thereby completing the maintenance work on the drain pipe.

[0030] In the interpretation of the present invention, it should be noted that the terminology indicating the orientation is only for the convenience of description and understanding, and is not the only limitation on the installation position of the specific technical features, and does not exclude other possible installation methods.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
