Detailed Description
The present invention is described in further detail below with reference to fig. 1.
As shown in fig. 1, the flood-proof pipe comprises a pipe body 1, which is used for being installed on a vertical drainage pipe 2; and the safety valve 3, the safety valve 3 sets up in the body 1, and when the water level in the drainage riser 2 reached warning water level, the safety valve 3 opened. The cross section of the tube body 1 in this embodiment is circular, and in other embodiments, the cross section may also be rectangular or other shapes.
As shown in fig. 1, an alarm system 4 is arranged on the pipe body 1, and the alarm system 4 comprises an audible and visual alarm. The pressure sensor 5 is used for measuring the water pressure in the vertical drainage pipe 2, the pressure sensor 5 is a strip sensor, the pressure sensor 5 comprises a lead and a probe used for measuring a pressure value, and the length of the lead is not less than the distance from the pipe body 1 to the bottom end of the vertical drainage pipe 2.
During installation, the conducting wire falls along the vertical drainage pipe 2 along the access opening 23, and the probe of the pressure sensor 5 can extend into the bottom end of the vertical drainage pipe 2. Once the blockage occurs, the water level in the vertical drainage pipe 2 rises, so that the pressure value measured by the pressure sensor 5 can reach a set value in time, the alarm system 4 can send out an audible and visual alarm signal in time, and enough reaction time is left for maintainers.
As shown in fig. 1, when the pressure value measured by the pressure sensor 5 is greater than the set value, the alarm system 4 sends out an audible and visual alarm signal. When the pressure value measured by the pressure sensor 5 is equal to the set value, the water level height of the vertical drainage pipe 2 is H1, and the height of H1 is lower than the access opening 23.
As shown in fig. 1, when the pressure value measured by the pressure sensor 5 is greater than the set value and reaches the threshold time T, the alarm system 4 sends out an audible and visual alarm signal and a blockage alarm signal, and transmits the blockage alarm signal to the duty room or the property control room. The threshold time T is a time preset by the alarm system 4, and T is greater than zero. After the water level in the vertical drainage pipe 2 rises to a position above the water level at which the pressure value of the pressure sensor 5 reaches the set value for a period of time, the alarm system 4 starts to work and sends out an acousto-optic alarm signal, so that misjudgment caused by the fact that the water level rises in a short time due to sudden increase of the drainage flow in the vertical drainage pipe 2 is avoided, and the accuracy of alarm is improved.
In addition, as shown in fig. 1, one end of the pipe body 1 far away from the vertical drainage pipe 2 is communicated with a drainage hose 6, and the safety valve 3 is arranged in the pipe body 1 between the access opening 23 and the drainage hose 6; the drain hose 6 may communicate with an outdoor drain or bilge well 7. Because of body 1 has a take the altitude apart from ground, installation drainage hose 6 on body 1, the other end of drainage hose 6 can be placed on outdoor lawn or escape canal, avoids sewage direct from body 1 discharge and leads to sewage to splash, influences market appearance and environment.
As shown in figure 1, the drainage anti-flooding structure comprises a vertical drainage pipe 2 and a horizontal drainage pipe 21, wherein the bottom end of the vertical drainage pipe 2 is communicated with the horizontal drainage pipe 21, and the horizontal drainage pipe 21 is communicated with a sewage well 7. The horizontal drainage pipe 21 is horizontally arranged and buried under the ground. The vertical drainage pipe 2 is communicated with a bottom user drainage branch pipe 22. The users at the bottom floor are users at second floor or third floor, and because the users at the first floor usually set the drainage pipe independently, only the users at the second floor or above the third floor share one drainage vertical pipe 2; thus, the bottom layer user drain branch 22 herein refers to the drain branch of the lowest layer user of the common drain stand pipe 2.
Wherein the warning water level H2 for driving the safety valve 3 to open is lower than the distance between the pipe body 1 and the bottom user drain branch pipe 22. So that the safety valve 3 can be opened for emergency drainage after the blockage occurs before the water level reaches the user room at the bottom.
The vertical drainage pipe 2 is provided with a flood-proof pipe, and a pipe body 1 of the flood-proof pipe is communicated with the vertical drainage pipe 2. The drainage vertical pipe 2 is provided with an access hole 23, the access hole 23 is arranged when the drainage vertical pipe 2 is installed, and the height of the access hole 23 is usually 1-2m away from the ground.
The access hole 23 is positioned between the drainage branch pipe and the drainage transverse pipe 21 at the lower layer, and the pipe body 1 is arranged at the access hole 23; the pipe body 1 is in threaded connection with the access hole 23.
During installation, only the sealing screw cap at the access opening 23 needs to be unscrewed, the pipe body 1 is in threaded connection with the access opening 23, and the pipe body 1 is screwed; need not in addition to carry out operations such as trompil to drainage riser 2, it is convenient to reform transform the drainage riser 2 that has operated, and the installation cost is low.
The specific working process is as follows: the anti-flooding pipe is arranged on the vertical drainage pipe 2, if the horizontal drainage pipe 21 is blocked, the drainage section of the horizontal drainage pipe 21 is reduced, and drainage starts to be unsmooth. When large-flow drainage is carried out, the drainage transverse pipe 21 can be filled with water in a short time, and water begins to accumulate in the drainage vertical pipe 2, so that the pressure value measured by the pressure sensor 5 is gradually increased; after the water level gradually rises to above H1, when the pressure value is greater than the set value and a period of time T is elapsed, the alarm system 4 sends out an audible and visual alarm signal to prompt that the horizontal drainage pipe 21 communicated with the vertical drainage pipe 2 is blocked, and after the blockage is eliminated, the audible and visual alarm signal is removed, and the alarm system 4 is recovered.
If the blockage is not eliminated, even the pipeline is completely blocked, the water level of the vertical drainage pipe 2 continues to rise, and after the water level rises to the warning water level H2, the safety valve 3 is opened, so that the sewage in the vertical drainage pipe 2 is emergently discharged into emergency drainage points such as an outdoor lawn or an outdoor water distribution ditch, and the sewage is prevented from overflowing into rooms of users at the bottom layer due to untimely maintenance of maintainers. At the moment, the alarm system 4 continuously sends out audible and visual alarm signals, and sends the blockage alarm signals to the duty room until the pipeline is cleared, and the alarm system 4 is reset.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
