Technical Field

[0001] The utility model belongs to the technical field of municipal drainage, and particularly relates to a device for quickly taking out a drainage pipe blocking air bag. Background Art

[0002] Airbag plugging is required during the inspection, rectification and repair of drainage pipe networks. When the upstream water pressure is too high, the airbag is easily rushed from the pipe mouth to the middle of the pipe under the action of water pressure and stuck, causing the pipe to lose its flow capacity and cause overflow. If the airbag in the middle of the pipe is removed manually, it is very risky. Therefore, it is necessary to develop a method to quickly remove the airbag and restore the flow capacity of the pipe in time. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 As shown, as a preferred embodiment of the utility model, this embodiment provides a device for quickly removing a drainage pipe blocking airbag, comprising a fixed rod 1 and an adjusting sleeve 2 sleeved on the fixed rod 1, the fixed rod 1 is threadedly connected to the adjusting sleeve 2, the end of the adjusting rod 1 extends out of the adjusting sleeve 2, a connecting ring 3 is provided at the end of the fixed rod 1, a plurality of blades 4 are evenly distributed on the connecting ring 3, the blades 4 are all hinged to the connecting ring 3, a pushing ring 5 is provided at the end of the adjusting sleeve 2, the pushing ring 5 is slidably connected to the end of the adjusting sleeve 2, a pushing arm 6 is hinged to the middle part of the pushing ring 5 and each of the blades 4, so that when the pushing ring 5 moves toward the connecting ring 3, the pushing arm 6 pushes the blades 4 to open into an umbrella rib shape, and when the pushing ring 5 moves away from the connecting ring 3, the pushing arm 6 pulls the blades 4 to shrink into a rod shape.

[0018] In some embodiments, in order to extend the service life and improve the anti-corrosion performance, the fixing rod 1 and the adjusting sleeve 2 in this embodiment are both made of stainless steel.

[0019] In some preferred embodiments, in order to prevent the airbag from being unable to be quickly punctured and to improve operating efficiency, a conical piercing head 7 is also provided at the end of the connecting ring 3 in this embodiment. During operation, the conical piercing head 7 can be used to quickly puncture the airbag and quickly extend the blade 4 into the airbag.

[0020] In some preferred embodiments, see the attached Figure 2 In order to ensure that the blade 4 enters the airbag smoothly and prevent the blade from puncturing the airbag again when the airbag is pulled, the outer side of the blade 4 in this embodiment is set to be a blade shape, and the inner side of the blade 4 is set to be a smooth arc surface, especially the end of the blade adopts a smooth curved surface structure. When the airbag is pulled, the contact part between the blade 4 and the airbag is smooth, thereby avoiding puncturing the airbag again, resulting in the inability to smoothly remove the airbag.

[0021] In some embodiments, in order to facilitate control and adjustment, a handle 8 is provided on the adjusting sleeve 2 in this embodiment, and the handle 8 is used to quickly rotate the adjusting sleeve 2.

[0022] In some embodiments, in order to facilitate storage, a fixing ring 9 is provided on the fixing rod 1 in this embodiment, and the entire device can be hung and stored through the fixing ring 9 when the operation is completed.

[0023] When the above embodiment is in operation:

[0024] 1) In the initial state, the blade is closed and the fixing rod is facing the blocking airbag as a whole;

[0025] 2) When reaching the blocking airbag, use the blade edge or the piercing head 7 of the blade to pierce the blocking airbag;

[0026] 3) Then continue to move the fixing rod forward as a whole, so that the blades are completely inside the airbag;

[0027] 2) Turn the adjusting sleeve 2 so that the adjusting sleeve 2 pushes the pushing ring 5 forward. At this time, the pushing arm 6 pushes the blade to open into an umbrella rib shape, and then pulls the fixing rod 1 backward to make the free end of the blade 4 contact the inner wall of the airbag. Continue to pull the fixing rod 1, use the umbrella rib-shaped end of the blade to bring out the airbag, and finally take it out from the inspection wellhead.

[0028] When the operation is completed, the adjusting sleeve 2 is rotated to shrink the blade 4 into a rod shape for easy storage.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
