Description

Technical Field

[0001] This utility model relates to the field of branch pipe technology, specifically a temporary branch pipe for water supply and drainage. Background Technology

[0002] Building water supply and drainage pipes are piping systems within buildings used to transport clean water (water supply) and discharge wastewater (drainage). Drainage pipes are used to collect domestic sewage and wastewater and discharge them to external pipe networks or treatment facilities.

[0003] The aforementioned device lacks a drainage branch pipe filtration and discharge structure during use. As a result, existing drainage pipes often have branch pipes installed to divert wastewater to another pipe for discharge and to facilitate maintenance of the blocked pipe below. However, since the branch pipe is smaller than the drainage pipe, it is very easy for the branch pipe to become blocked if the wastewater contains large waste or impurities, which can lead to the simultaneous blockage of multiple pipes and make maintenance difficult. Based on the shortcomings of existing technology, this utility model designs a temporary branch pipe for water supply and drainage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temporary branch connection for water supply and drainage, which has the advantages of filtering and discharging through drainage branch pipes.

[0005] This utility model provides the following technical solution: a temporary branch pipe for water supply and drainage, including a main pipe, a filter box is provided on one side of the main pipe, and a filter mechanism is provided inside the filter box to facilitate the filtration of drainage;

[0006] The filtration mechanism includes a side plate, a limiting post, a lifting plate, a rotating groove, a side frame, a cam, a rotating rod, a pull rod, a filter cartridge, a support plate, and a sealing gasket. The side plate is fixedly connected to both sides of the inner wall of the filter box. The limiting post is slidably connected to the side plate. The lifting plate is fixedly connected to the top of the limiting post. The rotating groove is formed through the side plate. The side frame is fixedly connected to the lower surface of the side plate. The cam is rotatably connected inside the rotating groove. The rotating rod is fixedly connected to both sides of the cam. The pull rod is fixedly connected to the cam. The filter cartridge is disposed inside the filter box. The support plate is fixedly connected to the filter cartridge. The sealing gasket is fixedly connected to the top of the filter cartridge.

[0007] As a preferred embodiment of this utility model, the top end of the main pipe is fixedly connected to a water inlet, the bottom end of the main pipe is fixedly connected to a water outlet, an upper branch pipe is provided on one side of the main pipe, and a water shut-off valve is provided on the main pipe.

[0008] As a preferred technical solution of this utility model, a fixing frame is fixedly connected to one side of the filter box, a water inlet is opened at the top of the filter box, a lower branch pipe is fixedly connected to the bottom of the filter box, a side window is opened on one side of the filter box, a threaded hole is opened on one side of the filter box, a sealing plate is covered on the side window, and a fixing bolt is connected through the sealing plate.

[0009] In a preferred embodiment of this invention, the sidewall of the cam contacts the lower surface of the lifting plate, and the rotating rod is rotatably connected inside the side frame.

[0010] In a preferred embodiment of this invention, the support plate is disposed on the upper surface of the lifting plate, and the sealing gasket is in contact with the top of the inner cavity of the filter box.

[0011] As a preferred embodiment of this utility model, the bottom of the side plate is provided with a buckle, and the pull rod is locked in place within the buckle after being closed and locked.

[0012] As a preferred embodiment of this utility model, the fixing bolt is threaded into the inside of the threaded hole, the bottom end of the lower branch pipe is connected to other pipelines, and an opening and closing valve is provided between the lower branch pipe and other pipelines.

[0013] As a preferred embodiment of this utility model, the bottom end of the upper branch pipe is fixedly connected to the water inlet, and the water shut-off valve is located below the connection between the main pipe and the upper branch pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This temporary branch pipe for water supply and drainage allows for branch filtration and drainage of the main pipe when necessary. First, the shut-off valve is closed and the valve at the bottom of the lower branch pipe is opened. The sewage flowing in the main pipe is blocked by the shut-off valve and enters the filter box from the upper branch pipe. The sewage entering the filter box enters the filter cartridge directly through the inlet hole for filtration. The filtered sewage flows into the bottom of the inner cavity of the filter box and is discharged to other pipelines through the lower branch pipe. This device facilitates branch filtration and drainage of the main pipe.

[0016] 2. This temporary branch pipe for water supply and drainage is designed to open the side window by unscrewing the fixing bolts from the filter box using a tool. Then, by holding the pull rod and pushing it downwards, the cam rotates under the limit of the rotating rod and the side frame. The rotating cam contacts the lower surface with the lifting plate, reducing the pushing height of the lifting plate. At this time, the lifting plate begins to move downwards under the limit of the limit post, and the filter cartridge and support plate placed on the lifting plate move downwards accordingly, causing the sealing gasket to disengage from the top of the inner wall of the filter box. Finally, the handle on the support plate is pulled to remove the filter cartridge, clean the filtered dirt, and reinsert it into the filter box. The pull rod is then lifted upwards to use the cam to push the lifting plate upwards, causing the filter cartridge and support plate to move upwards again and the sealing gasket to contact and fix with the top of the inner wall of the filter box. This device facilitates the cleaning of the filter cartridge. Attached Figure Description

[0026] The filter cartridge 309, support plate 310, and sealing gasket 311 are provided to filter the sewage entering the filter box 2. The side plate 301, limiting column 302, and lifting plate 303 are provided to support the filter cartridge 309 by placing the support plate 310. The rotating groove 304, side frame 305, cam 306, rotating rod 307, and pull rod 308 are provided to control the lifting and fixing of the filter cartridge 309 and support plate 310.

[0027] Please see Figure 3-4A fixing bracket 201 is fixedly connected to one side of the filter box 2. A water inlet hole 202 is opened on the top of the filter box 2. A lower branch pipe 203 is fixedly connected to the bottom of the filter box 2. A side window 204 is opened on one side of the filter box 2. A threaded hole 205 is opened on one side of the filter box 2. A sealing plate 206 is installed on the side window 204. A fixing bolt 207 is threaded through the sealing plate 206. The fixing bolt 207 is threaded into the inside of the threaded hole 205. The bottom end of the lower branch pipe 203 is connected to other pipes, and an opening and closing valve is provided between the lower branch pipe 203 and other pipes.

[0028] By setting a fixing bracket 201, the filter box 2 can be fixed on the main pipe 1. By setting an inlet hole 202 and a lower branch pipe 203, and connecting the inlet hole 202 to the upper branch pipe 103, the sewage in the main pipe 1 can be diverted into the filter box 2, filtered by the filtration mechanism 3, and then discharged to the outside or into another pipeline.

[0029] Working principle: When a temporary branch pipe for water supply and drainage is used, in the initial state, a shut-off valve 104 is first installed on the main pipe 1, and the filter box 2 is fixed to the main pipe 1 by a fixing bracket 201. The bottom end of the upper branch pipe 103 installed on one side of the main pipe 1 is connected to the water inlet hole 202 opened on the top of the filter box 2, and the upper branch pipe 103 is installed at the bottom of the filter box 2 so as to divert the sewage in the main pipe 1 to the filter box 2 and drain it through the lower branch pipe 203. A filtration mechanism 3 is installed in the filter box 2 to filter the sewage diverted to the filter box 2, so as to prevent the filter box 2, the lower branch pipe 203 and the downstream pipe from becoming blocked after the main pipe 1 is blocked.

[0030] When branch filtration and drainage of the main pipe 1 is required, first close the shut-off valve 104 and open the valve at the bottom of the lower branch pipe 203. The sewage flowing in the main pipe 1 is blocked by the shut-off valve 104 and enters the filter box 2 from the upper branch pipe 103. The sewage entering the filter box 2 enters the filter cartridge 309 directly through the inlet hole 202 for filtration. The filtered sewage flows into the bottom of the inner cavity of the filter box 2 and is discharged to other pipelines through the lower branch pipe 203. This device facilitates branch filtration and drainage of the main pipe 1.

[0031] When cleaning the filter cartridge 309 is required, first use a tool to unscrew the fixing bolt 207 from the filter box 2 to open the side window 204. Then, hold the pull rod 308 and push it downwards to make the cam 306 rotate under the limit of the rotating rod 307 and the side frame 305. The rotating cam 306 will bring its lower surface into contact with the lifting plate 303, reducing the pushing height of the lifting plate 303. At this time, the lifting plate 303 begins to move downwards under the limit of the limit post 302, and drives the filter cartridge 309 placed on the lifting plate 303. 09 and support plate 310 move down to disengage the sealing gasket 311 from the top of the inner wall of the filter box 2. Finally, pull the handle on support plate 310 to remove the filter cartridge 309, clean the filtered dirt, and reinsert it into the filter box 2. Lift the pull rod 308 upward and use cam 306 to push the lifting plate 303 upward, so that the filter cartridge 309 and support plate 310 move upward again and the sealing gasket 311 contacts and fixes itself to the top of the inner wall of the filter box 2. This device facilitates the cleaning of the filter cartridge 309.
