Description

Technical Field

[0001] The invention relates to the field of building drainage systems, in particular to a building drainage pipe network structure with a self-cleaning function. Background Art

[0002] Building drainage contains various impurities, such as sand, hair, grease, etc., which will form dirt on the inner wall of the pipe after long-term accumulation. The currently commonly used manual cleaning method is not only inefficient, but also requires a lot of manpower and time costs. Moreover, for some complex pipeline layouts, it is difficult for manual labor to reach certain parts for thorough cleaning, resulting in increasingly serious dirt accumulation, affecting the drainage effect.

[0003] The accumulation of dirt in the drainage network will gradually reduce the flow cross-sectional area of ​​the pipe. When the dirt accumulates to a certain extent, it is very easy to cause pipe blockage. Pipe blockage will not only cause poor drainage and sewage overflow, causing great inconvenience to residents' lives, but may also damage the structure of the building and increase maintenance costs.

[0004] Most of the existing building drainage pipe networks do not have self-cleaning functions and cannot automatically remove dirt during the drainage process, and can only rely on regular manual maintenance. This not only increases maintenance costs, but also makes it difficult to ensure that the pipes are always in good drainage conditions, and cannot meet the needs of modern buildings for efficient and convenient drainage systems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a building drainage pipe network structure with a self-cleaning function, which solves the problem that most of the existing building drainage pipe networks do not have a self-cleaning function and cannot automatically remove dirt during the drainage process, and can only rely on regular manual maintenance. This not only increases the maintenance cost, but also makes it difficult to ensure that the pipes are always in a good drainage state, and cannot meet the needs of modern buildings for efficient and convenient drainage systems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a building drainage pipe network structure with a self-cleaning function, comprising:

[0007] The shell as a supporting component has a plug-in drill bit connected to one side thereof by plugging and fixed by a fixing assembly. After plugging, the end of the plug-in drill bit is deformed to move inwards to achieve the purpose of clamping. A flip arm is connected to the middle of the outer wall of the shell through an expansion assembly to achieve the flip arm flipping outwards. The end of the flip arm is connected to the plug-in drill bit through a leakage screen cover.

[0008] A straight pipe, the end of which is connected to a curved pipe, an external cover is installed on one side of the outer arc of the curved pipe, a discharge valve is provided at the bottom of the external cover, and a conical cavity is provided inside the external cover, a draw rope is provided at the inner center of the straight pipe, and the end of the draw rope passes through the external cover and extends outward, holes connected to the draw rope are provided inside the shell and the plug-in drill bit, and the shell and the plug-in drill bit are located inside the straight pipe.

[0009] Preferably, the top end of the curved pipe is connected to a connecting pipe to achieve pipeline connection.

[0010] Preferably, both ends of the pull rope are connected to a winding machine, and the working states of the two winding machines are opposite.

[0011] Preferably, a plug-in groove is provided on one side of the shell, a plug-in plate is threadedly connected to one side of the plug-in drill bit, a buffer pad is fixedly connected to the outer wall of the plug-in plate, and a deformation space for moving inward is provided on the left side of the outer wall of the plug-in plate.

[0012] Preferably, the inner wall of the plug-in plate is provided with a plurality of barbs for clamping and hooking the pull-out rope after deformation, thereby achieving fixation between the housing, the plug-in drill bit and the pull-out rope.

[0013] Preferably, the installation assembly includes a reserved installation hole on one side of the shell, the shell and the plug board are fixed by bolts, and the bolts are located inside the reserved installation hole, and a sealing plug is provided inside the reserved installation hole.

[0014] Preferably, the expansion assembly includes a rotation groove opened in the middle of the outer wall of the shell, the flip arm is located inside the rotation groove and rotatably connected, and a torsion spring is provided at the connection to enable the flip arm to flip outward and fit the inner wall of the straight tube.

[0015] The self-cleaning method of the building drainage pipe network structure comprises the following steps:

[0016] Step 1: Install and debug the winding machine to ensure that the pull rope can be normally retracted and released under the control of the winding machine. Check whether the connection between the plug-in drill bit and the housing is firm, whether the barbs on the plug-in board are intact, whether the flip arm can rotate flexibly in the rotating groove, and whether the torsion spring elasticity is normal;

[0017] Step 2: Start one of the winding machines to start winding the pull rope. The pull rope drives the housing and the plug-in drill bit to move in the straight pipe. As the pull rope is pulled, the plug-in drill bit goes deeper into the straight pipe. The clamping force generated by the deformation of its end keeps itself moving stably. During the movement, the plug-in drill bit can push the dirt inside the pipe.

[0018] Step 3: Due to the pulling of the pull rope, the flip arm begins to flip outward under the action of the torsion spring and fits the inner wall of the straight pipe, wiping the inner wall of the pipe more comprehensively to scrape off the dirt. During this period, the filter cover can filter out larger impurities in the water to prevent them from accumulating in the pipe;

[0019] Step 4: When the cleaning component moves to the end of the straight pipe, open the discharge valve to discharge the dirt, start another winding machine with the opposite working state to reel in the pull rope and retract the cleaning component from the pipe.

[0020] Preferably, when starting cleaning in step 2:

[0021] If there is a lot of dirt in the pipe and it is stubborn, the winding speed of the winding machine should be set to 1 to 2 revolutions per minute;

[0022] If there is less dirt, the winding speed of the winding machine is increased to 3 to 5 revolutions per minute.

[0023] The present invention provides a building drainage pipe network structure with a self-cleaning function. It has the following beneficial effects:

[0024] 1. The present invention provides structures such as a plug-in drill bit, a flip arm and a drain screen, and uses a pull rope to drive these components to move in the pipeline to achieve automatic cleaning of the dirt on the inner wall of the pipeline. The plug-in drill bit can push the dirt, the flip arm can wipe the inner wall of the pipeline to scrape off the dirt, and the drain screen can filter impurities, effectively reducing the accumulation of dirt in the pipeline and keeping the pipeline unobstructed.

[0025] 2. The present invention reasonably adjusts the winding speed of the winding machine according to the different conditions of the dirt in the pipeline. When the dirt is large and stubborn, a lower speed is used for cleaning to ensure that the cleaning parts have enough time to contact the dirt; when the dirt is small, the speed is increased to improve the cleaning efficiency and save cleaning time.

[0026] 3. The reserved mounting holes and bolts in the mounting assembly of the present invention facilitate the installation and removal of the plug board and the housing, and the setting of the sealing plug ensures the sealing of the connection. At the same time, the discharge valve at the bottom of the external cover facilitates the discharge of dirt generated during the cleaning process, which is convenient for the maintenance and management of the drainage network.

The housing 9, the plug-in drill bit 6 and the pull rope 3 are fixed to each other. After the bolt is unscrewed, the plug-in drill bit 6 is pulled outward, and the plug-in plate 13 starts to return to its position to separate the plug-in drill bit 6 from the housing 9. After separation, the pull rope 3 is passed through the housing 9 and the plug-in drill bit 6 in sequence again and fixed. The end of the pull rope 3 is reconnected to the winding machine, and the work can continue. A rotating groove 10 is provided in the middle of the outer wall of the housing 9. The flip arm 8 is located in the internal rotation connection of the rotating groove 10, and a torsion spring is provided at the connection to realize the flip arm 8 flipping outward and fitting the inner wall of the straight tube 1. The end of the flip arm 8 is connected to the plug-in drill bit 6 through the leakage screen cover 7;
