Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a drainage pipe backflow prevention alarm device. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they serve the purpose of drainage, they should be counted as drainage pipes.

[0003] However, most of the drainage pipes in the prior art do not have the function of preventing backflow, which causes the sewage in the drainage pipe to flow back. At the same time, the existing drainage pipes are not equipped with alarm devices. Therefore, after the drainage is completed, the user cannot judge whether the sewage in the drainage pipe has flowed back, which greatly reduces the practicality of the drainage pipe. In order to solve the above-mentioned problems, the utility model provides a drainage pipe anti-backflow alarm device. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and provide a drainage pipe backflow prevention alarm device.

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0017] like Figure 1-3 As shown, an embodiment of the utility model proposes a drain pipe backflow prevention alarm device, comprising a drain pipe 1, to which a transfer pipe 2 is connected, and is characterized in that: the inner surfaces of the left and right ends of the drain pipe 1 are provided with internal thread sections 101, the drain pipe 1 is provided with an anti-backflow component 3, and the transfer pipe 2 is provided with an alarm component 4.

[0018] When in use, connect one end of the drain pipe 1 to the drain outlet of the equipment that needs drainage. After the equipment completes drainage, in order to prevent the water in the drain pipe 1 from flowing back, the water in the drain pipe 1 can be prevented from flowing back through the backflow prevention component 3. If the backflow prevention component 3 cannot effectively prevent the water in the drain pipe 1 from flowing back, the alarm component 4 will sound an alarm to remind the staff that the water in the drain pipe 1 has flowed back, so that the staff can deal with the backflow of the water in the drain pipe 1 in time.

[0019] like Figure 1 and Figure 3 As shown, in some embodiments, the backflow prevention assembly 3 includes a rotating rod 31 rotatably installed in the drain pipe 1, both ends of the rotating rod 31 pass through the drain pipe 1, a fixing plate 32 is fixedly installed at one end of the rotating rod 31, and two baffles 33 are fixedly sleeved on the outer surface of the rotating rod 31, and the two baffles 33 are both located in the drain pipe 1, and a limiting assembly 5 is provided on the outer surface of the drain pipe 1.

[0020] When water in the drain pipe 1 flows back, the staff can manually rotate the fixed plate 32 to drive the rotating rod 31 to rotate, thereby driving the two baffles 33 fixed on the outer surface of the rotating rod 31 to rotate synchronously, so that the two baffles 33 block the drain pipe 1, thereby preventing the water in the drain pipe 1 from flowing back, and use the limiting component 5 to limit and fix the fixed plate 32 to prevent the impact force generated by the flow of water from pushing the two baffles 33 to rotate, so that the two baffles 33 cannot block the drain pipe 1. Similarly, when drainage is needed, the fixed plate 32 is rotated again, and the two baffles 33 are adjusted to make the two baffles 33 parallel to the drain pipe 1, so that the water in the drain pipe 1 can flow down normally.

[0021] like Figure 2 As shown, in some embodiments, the alarm assembly 4 includes a connecting rod 41 rotatably installed in the transfer tube 2, a circular plate 42 is fixedly sleeved on the outer surface of the connecting rod 41, a thin rope 43 is fixed to the bottom of the circular plate 42, a float 44 is fixed to one end of the thin rope 43, a mounting plate 45 is fixedly installed in the transfer tube 2, and a water immersion alarm 46 is fixed to the top of the mounting plate 45.

[0022] When the backflow prevention component 3 cannot effectively prevent the water in the drain pipe 1 from flowing back, the water in the drain pipe 1 will flow back into the transfer pipe 2, and the liquid level will continue to rise. When the liquid level contacts the float 44, the float 44 will float up and push the circular plate 42 upward, so that the water in the transfer pipe 2 will submerge the circular plate 42. At the same time, the liquid level will continue to rise. When the water in the transfer pipe 2 submerges the mounting plate 45 and contacts the water immersion alarm 46, the water immersion alarm 46 will sound an alarm through its own alarm speaker, thereby achieving the effect of early warning.

[0023] like Figure 1 and Figure 3 As shown, in some embodiments, the limiting assembly 5 includes a ring 51 mounted on the outer surface of the drain pipe 1, and two limiting blocks 52 are symmetrically arranged and fixed on the outer surface of the ring 51. A sliding block 53 is slidably installed on the outer surface of the ring 51, and the sliding block 53 is U-shaped.

[0024] When it is necessary to limit and fix the fixing plate 32, if the fixing plate 32 and the drain pipe 1 are in a horizontal state, manually push the ring 51 so that the ring 51 approaches the fixing plate 32 along the outer surface of the drain pipe 1, and then clamp the fixing plate 32 between the two limit blocks 52 to prevent the water flow in the drain pipe 1 from pushing the two baffles 33 to rotate, thereby driving the fixing plate 32 to rotate; if the fixing plate 32 and the drain pipe 1 are in a vertical state, push the ring 51 to move it to one side of the fixing plate 32, and then pull the sliding block 53 to make it slide along the outer surface of the ring 51, and clamp the fixing plate 32 between the sliding blocks 53, thereby achieving the limit and fixation of the fixing plate 32.

[0025] like Figure 1 As shown, in some embodiments, a sealing cover 6 is detachably mounted on the top of the transfer tube 2 .

[0026] The sealing cover 6 makes it convenient for the staff to repair or install the water flood alarm 46 .

[0027] like Figure 2 As shown, in some embodiments, the outer surface of one end of the transfer tube 2 is provided with an external thread 7 , and the inner surface of the sealing cover 6 is provided with an internal thread 8 matched with the external thread 7 .

[0028] When the water flood alarm 46 needs to be installed or repaired, the sealing cover 6 can be directly rotated to remove it from one end of the transfer tube 2.

[0029] Finally, the most important contribution of the utility model is that the anti-backflow component 3 arranged in the drain pipe 1 can make the water in the drain pipe 1 flow down normally, and at the same time can effectively prevent the water in the drain pipe 1 from flowing back. If the anti-backflow component 3 cannot effectively prevent the water from flowing back, the water in the drain pipe 1 flows into the transfer pipe 2 and lifts the float 44 in the alarm component 4. At this time, the circular plate 42 rotates, and the water in the drain pipe 1 continues to flow back. When the water in the transfer pipe 2 contacts the water immersion alarm 46 on the mounting plate 45, the water immersion alarm 46 will sound an alarm, thereby reminding the staff that the water in the drain pipe 1 has flowed back.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
