TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage drainage systems, in particular to an intelligent detection and alarm sewage backflow prevention device. BACKGROUND

[0002] The indoor drainage pipe of a multi-storey or high-rise building is composed of horizontal pipes of each floor and a common vertical pipe. The horizontal pipes are connected to the common vertical pipe, the common vertical pipe is connected to the ground and then connected to a municipal well through a buried horizontal section.

[0003] In actual use, the sewage and waste water discharged by the residents may contain a large amount of garbage, which can easily cause pipe blockage in the buried horizontal section of the common vertical pipe, causing the drainage system to fail. The sewage and waste water of high floors cannot be discharged into the municipal well in time, and when the accumulated water head in the vertical pipe exceeds the floor height of the lower floors, the sewage will flow back to the indoor through the indoor toilet, kitchen drain, floor drain, etc., causing indoor decoration pollution and damage, and affecting the normal use of the residents.

[0004] To reduce the occurrence of indoor backflow, regulations require that the drainage system of the first floor residents be designed as an independent sewer. This method can effectively solve the backflow problem of the first floor residents, but the second floor and above cannot be designed as an independent sewer. Therefore, the lower floors of the second floor and above can only be managed by the property management company, but manual supervision cannot achieve long-term seamless monitoring and can only be supervised by regular detection, which can still cause pipe blockage and sewage backflow. Therefore, the management method of the property management company cannot solve the actual problem. CONTENT OF THE INVENTION

[0011] An alarm is arranged on the end cover and connected with the probe to give an alarm according to the signal of the probe.

[0012] According to the technical scheme, due to the double effects of gravity and water flow impact, the vertical section of the common vertical pipe is not prone to be blocked, and the blocking position is usually located in the horizontal section of the buried pipe. The detection pipe is arranged on the vertical section of the common vertical pipe at a specified distance from the ground. During the sewage backflow process, sewage will first enter the detection pipe and then be detected by the probe before backflowing into the house, and then the alarm will alarm. Since there is a period of time from the full detection opening to the indoor backflow, as long as the alarm is timely, there is sufficient time to dredge and respond to the horizontal section of the common vertical pipe.

[0013] Optionally, the probe includes a positive metal probe and a negative metal probe, the positive metal probe and the negative metal probe are separated from each other in a normal state, the positive metal probe is connected with a positive electrode of the alarm, the negative metal probe is connected with a negative electrode of the alarm, and the alarm alarms when a circuit closed loop is formed between the positive metal probe, the negative metal probe and the alarm.

[0014] Optionally, the end of the detection pipe is provided with a sealing ring, and the inner wall of the end cover abuts against the sealing ring.

[0015] Optionally, a sealing block is arranged on the inner wall of the end of the end cover, and the sealing block is embedded in the end of the detection pipe in cooperation with sliding.

[0016] Optionally, a mounting groove is arranged on the side of the end cover away from the detection pipe, the alarm is mounted in the mounting groove, a protective cover is arranged in the mounting groove, and the protective cover covers the alarm.

[0017] Optionally, an open-type battery compartment is arranged on the side of the alarm away from the detection pipe.

[0021] Optionally, a filter screen cover is arranged on the probe to filter impurities in the sewage.

[0022] In summary, in the sewage backflow process, the sewage will first enter the detection pipe before backflowing into the house, and then the probe will detect it, and the alarm will alarm. Since there is still a period of time from the full detection opening to the indoor backflow, as long as the alarm is timely, there is sufficient time to dredge and respond to the horizontal section of the public vertical pipe.

The detection pipe 1 is generally set to be 1 meter away from the ground, and the specific height from the ground can be adjusted according to the local situation.

[0033] With reference to Figure 2 and Figure 3 , a cylindrical end cover 2 is threadedly mounted on one end of the detection tube 1, the end cover 2 is provided with a probe 3 on the side facing the inside of the detection tube 1, and an alarm 4 is provided on the side of the end cover 2 facing away from the inside of the detection tube 1, the probe 3 is used to detect the water level inside the detection tube 1, and the alarm 4 is in communication with the probe 3 and alarms when the probe 3 detects that the water level exceeds the warning line.

[0034] With reference to Figure 2 and Figure 3 , the probe 3 includes a positive metal probe 31 and a negative metal probe 32, one end of the positive metal probe 31 is electrically connected to the positive electrode of the alarm 4, and one end of the negative metal probe 32 is electrically connected to the negative electrode of the alarm 4, the alarm 4 is driven by a battery, when sewage backwash enters the inside of the detection tube 1 and the water level exceeds the positive and negative metal probes 32, the positive and negative metal probes 32 are connected by water, the alarm 4 forms a closed loop circuit, and the alarm 4 is started to issue an alarm.

[0035] With reference to Figure 2 and Figure 3 , a filter screen 5 is covered outside the positive and negative metal probes 31 and 32, the filter screen 5 is used to filter impurities in the sewage, and prevent impurities from adhering to the positive and negative metal probes 31 and 32 to form an insulating layer and cause detection failure. The positive and negative metal probes 31 and 32 are made of corrosion-resistant metal to increase the service life of the positive and negative metal probes 31 and 32.

[0036] With reference to Figure 2 and Figure 3 , a rubber sealing ring 11 is provided between the end cover 2 and the end face of the detection tube 1, and a sealing block 21 is integrally provided on the inner wall of the end face of the end cover 2, and the sealing block 21 is embedded in the end of the detection tube 1. After tightening the end cover 2, the rubber sealing ring 11 is tightly attached to the inner wall of the end cover 2, the end face of the detection tube 1 and the side wall of the sealing block 21, so that a good seal is formed between the detection tube 1 and the end cover 2.

[0037] With reference to Figure 2 and Figure 3 , a circular mounting groove 22 is coaxially provided on the outer side wall of the end of the end cover 2, and the alarm 4 is fixedly installed in the mounting groove 22, and an open battery compartment is provided on the side of the alarm 4 facing away from the detection tube 1 to facilitate replacement of the battery of the alarm 4. A protective cover is threadedly mounted in the mounting groove 22 to cover the alarm 4, and the alarm 4 is protected by the protective cover to prevent damage to the alarm 4 due to external reasons.

[0038] With referenceFigure 2 and Figure 3 One end of the protective cover protrudes the mounting groove 22, so as to facilitate the dismounting and mounting of the protective cover. One end of the alarm 4 provided with the battery compartment also protrudes the mounting groove 22, so as to facilitate the mounting and dismounting of the battery.

[0039] The implementation principle of the intelligent detection and alarm anti-backflow device is as follows: when the sewage is backflowing along the vertical section of the public riser, the sewage will first enter the detection pipe 1 before entering the house, then the positive metal probe 31 and the negative metal probe 32 in the detection pipe 1 are connected and powered through the sewage, so as to form a closed loop of the circuit in the alarm 4, and the alarm 4 is started to issue an alarm. Since there is still a period of time from the sewage filling the detection pipe 1 to backflowing into the house, if the property department timely dredges the blocked pipeline, the sewage will not backflow into the house.

[0040] Embodiment 2, an intelligent detection and alarm anti-backflow device:

[0041] The difference between the embodiment 2 and the embodiment 1 is only that:

[0042] Referring to Figure 4 , the detection pipe 1 is inclined upward, and a detection rod 6 is rotatably installed in the detection pipe 1. One end of the detection rod 6 is fixedly installed with a hollow floating ball 61 made of corrosion-resistant material, and the other end of the detection rod 6 is fixedly installed with an arc-shaped metal sheet 62. The arc-shaped metal sheet 62 is coaxial with the rotating shaft of the detection rod 6, and the rotating axis of the detection rod 6 is horizontal. The arc-shaped metal sheet 62 can be rotated to abut and connect the positive metal probe 31 and the negative metal probe 32.

[0043] Referring to Figure 4 , the floating ball 61 is located at the lower end of the detection pipe 1. Under the action of the gravity of the lower end of the detection rod 6 and the floating ball 61, the arc-shaped metal sheet 62 is separated from the positive metal probe 31 and the negative metal probe 32 under the normal state. When the sewage backflows, the detection rod 6 rotates to drive the arc-shaped metal sheet 62 to move until the arc-shaped metal sheet 62 abuts and connects the positive metal probe 31 and the negative metal probe 32, the circuit of the alarm 4 forms a closed loop, and the alarm 4 is started.

[0044] Referring to Figure 4 , and when the arc-shaped metal sheet 62 abuts the positive metal probe 31 and the negative metal probe 32, the floating ball 61 abuts the upper inner side wall of the detection pipe 1, so that the arc-shaped metal sheet 62 and the positive metal probe 31 and the negative metal probe 32 are kept in contact.

[0045] Through the above scheme, the object in direct contact with the sewage is the floating ball 61 made of corrosion-resistant material, which has stronger corrosion resistance compared to corrosion-resistant metal. In areas where heavy rain does not cause rapid sewage backflow, although the installation difficulty is increased, the service life of the above scheme is longer, and the situation that the positive metal probe 31 and the negative metal probe 32 are connected due to the possible splashing of sewage into the detection tube 1 during daily sewage discharge, thereby causing the alarm 4 to be triggered mistakenly, is less likely to occur.

[0046] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
