Description

Technical Field

[0001] This utility model relates to the field of sewage pipeline treatment technology, specifically to a sewage pipeline internal cleaning device. Background Technology

[0002] Sewage pipe cleaning mainly involves removing blockages, deposits, and dirt from the pipes through physical, mechanical, or chemical means to ensure smooth drainage. Common internal treatment methods for sewage pipes typically involve inserting tools such as thin, long springs to twist and unclog them.

[0003] Existing dredging methods often fail to quickly and effectively loosen stubborn blockages when faced with them. This is due to the inherent elasticity of the cleaning devices themselves. Furthermore, the operation requires the operator to apply force towards the inside of the pipe, resulting in poor stability. Therefore, a sewage pipe internal cleaning device is proposed to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sewage pipe internal cleaning device, which has the advantage of conveniently clearing blockages in sewage pipes through both high-speed airflow and physical compression. It solves the problems of existing unblocking methods, which often fail to quickly and effectively loosen the target point when encountering stubborn blockages due to the elasticity of the cleaning device itself, and require the operator to apply force towards the inside of the pipe during use, resulting in poor stability.

The cleaning tube has multiple connecting holes on its outside that can be connected to a connecting joint. The threaded sleeve has a sealing block connected to its inside thread. The cleaning tube has an elastic sealing component inside that seals the connecting holes.

[0009] The beneficial effects of this utility model are:

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the embodiments, by Figure 1-4 The present invention provides a sewage pipe internal cleaning device, comprising a base plate 1, a clamping member 2 at the end of the base plate 1, a compressed gas control valve 3 fixedly installed on the outside of the base plate 1, a connecting joint 4 connected to the outlet of the compressed gas control valve 3, a positioning slider 5 slidably connected inside the base plate 1, a locking bolt for locking its position inside the positioning slider 5, and a cleaning pipe 6 slidably connected inside the positioning slider 5.

[0029] The cleaning tube 6 has a threaded sleeve 61 and a connecting sleeve 62 at its two ends. The connecting sleeve 62 has a thread on its outside that matches the thread on the inner wall of the threaded sleeve 61. The cleaning tube 6 has multiple connecting holes 63 on its outside that can connect with the connecting joint 4. The threaded sleeve 61 has a sealing block 64 connected to its inside thread. The cleaning tube 6 has an elastic sealing component 7 inside that seals the connecting holes 63.

[0030] Specifically, the external part of the connector 4 is provided with an air outlet. When the connector 4 is inserted into the connector hole 63, the air outlet is not affected by the sealing block 64. At the same time, when the cleaning tube 6 needs to be extended, the sealing block 64 can be removed directly, and another cleaning tube 6 can be taken. The first and last parts of the connecting sleeve 62 and threaded sleeve 61 of the two cleaning tubes can be connected to extend the length of the cleaning tube 6.

[0031] Furthermore, multiple agitators are provided on the outside of the end where the cleaning tube 6 is connected to the connecting sleeve 62, and the multiple agitators are distributed in a ring array.

[0032] By setting up a stirring plate, when encountering a position at the end that cannot be penetrated by high-pressure air, one end of the cleaning tube 6 can be held and repeatedly stirred at a certain angle without affecting the connection stability of the connector 4, so that the blockage at the end can be partially peeled off, making subsequent cleaning easier.

[0033] Furthermore, the elastic sealing assembly 7 includes a V-shaped elastic sheet 71 fixed to the inner wall of the cleaning tube 6, and a rubber block 72 extending into the connection hole 63 and pressed therewith to form a seal at the end of the V-shaped elastic sheet 71.

[0034] By setting a V-shaped elastic sheet 71, under normal circumstances, the V-shaped elastic sheet 71 applies elastic force to the rubber block 72 to seal the connection hole 63, thereby ensuring the sealing effect of the overall cleaning pipe 6. When necessary,

[0035] Furthermore, the bent end of the V-shaped elastic sheet 71 extends to the axis of the cleaning tube 6, and the V-shaped elastic sheet 71 is symmetrical on both sides of the bending point under normal conditions.

[0036] When there is airflow inside the cleaning pipe 6, the airflow impacts and squeezes the V-shaped elastic sheet 71, thereby giving it a component force that can further squeeze the rubber block 72, thus increasing the sealing effect of the rubber block 72. When there is positive pressure inside the cleaning pipe 6, the positive pressure can also apply pressure to the rubber block 72, ensuring the sealing performance of the rubber block 72.

[0037] Furthermore, the clamping member 2 includes a clamping base plate 21 fixed to the outside of the base plate 1, a clamping screw 22 is threadedly connected to the inside of the clamping base plate 21, and a clamping plate 23 is connected to the end of the clamping screw 22.

[0038] Furthermore, the clamping plate 23 is rotatably connected to the clamping screw 22, the end of the clamping plate 23 is flat and slides in contact with the base plate 1, and anti-slip pads are fixedly provided on the opposite sides of the clamping base plate 21 and the clamping plate 23.

[0039] When it is necessary to fix the device, the distance between the clamping base plate 21 and the clamping plate can be adjusted directly by the clamping screw 22 to complete the connection with the end of the pipe.

[0040] Working principle:

[0041] When this device is in operation, it is first connected to the end of the pipe through the clamp 2. Then, the position of the positioning slider can be adjusted by loosening the locking bolt to determine the position of the cleaning pipe 6. After the position is determined, the locking bolt is tightened again to complete the preparation work.

[0042] During the cleaning process, the cleaning pipe 6 is first inserted into the pipe until it comes into contact with the blockage. If the length of the cleaning pipe 6 is insufficient during insertion, it can be extended by using the threaded sleeve 61 and the connecting sleeve 62. After the cleaning pipe 6 is ready, the connecting joint 4 can be connected to the nearest connecting hole 63, and the compressed gas control valve 3 can be opened to fill the cleaning pipe 6 with compressed gas. The compressed gas is used to clear the blockage at the target point.
