Description

Technical Field

[0001] The utility model belongs to municipal engineering technology and is an automatic sewage discharge system for septic tanks in public toilets. Background Art

[0002] Sewage from urban public toilets is mainly discharged into septic tanks first. After the sewage enters the septic tank and settles, the solidified matter settles and decomposes at the bottom of the tank, and the hydrated matter is discharged into the sewage treatment plant through the municipal sewage pipe network. Some public toilets in cities and towns are too far away from the municipal sewage pipe network, and there are only temporary sewage pipes around them. Most of these temporary sewage pipes are shallow from the ground, and the septic tank outlet is too low, so the sewage cannot be directly discharged into the municipal sewage pipe network. The septic tank sewage can only be transported and discharged by suction trucks, which causes a huge waste of manpower and material resources. The automatic sewage discharge system for septic tanks in public toilets can automatically discharge sewage into temporary sewage pipes, and then into the municipal pipe network, effectively solving this problem. Summary of the invention

[0003] The utility model aims to solve the problem of difficult sewage discharge from septic tanks in urban public toilets.

[0004] The technical scheme of the utility model is as follows: the utility model is composed of a septic tank, a fixed bracket, a sewage pump, a steel wire rope, a sewage pump cable, a sewage pump control line, a sewage pipe, a cable-type float switch, a cable-type float switch fixing seat, a sewage pump control line, a distribution box circuit breaker, a distribution box switch power supply, a sewage pipe, and a municipal sewage pipe network. The septic tank is divided into a primary sedimentation chamber, a secondary sedimentation chamber, and a sewage chamber by a partition wall. First, the sewage pump cable, the sewage pump control line, and one end of the sewage pipe are connected to the sewage pump, and the other end is connected to the distribution box circuit breaker, the cable-type float switch, and the sewage pipe, respectively. The steel wire rope is fixed to the sewage pump, and is placed at a certain height in the sewage chamber, and the upper end of the steel wire rope is fixed to the fixed bracket. One end of the cable float switch's control line is connected to the sewage pump control line, and the other end is connected to the power switch of the distribution box. After the connection is completed, place the cable float switch in the sewage chamber, adjust the position of the cable float switch, and connect the cable float switch fixing seat to the fixing bracket. When the liquid level in the sewage chamber reaches the set high level, the cable float switch is turned on, and the sewage pump works to drain water. When the sewage level reaches the set low level, the cable float switch is disconnected, and the sewage pump stops working. This operation is repeated to realize the automatic discharge of septic tank sewage into the municipal sewage pipe network. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] Figure 1 It is a schematic diagram of the utility model. Specific implementation plan

[0006] The technical solution of the utility model is as follows: the utility model comprises a septic tank (1), a fixing bracket (5), a sewage pump (11), a steel wire rope (7), a sewage pump cable (6), a sewage pump control line (12), a sewage pipe (8), a cable-type float switch (14), a cable-type float switch fixing seat (13), a distribution box circuit breaker (3), a distribution box switch power supply (2), a sewage pipe (9), and a municipal sewage pipe network (10). The invention is characterized in that a septic tank (1) is divided into a primary sedimentation chamber (1-1), a secondary sedimentation chamber (1-2) and a sewage chamber (1-3) by a partition wall; a sewage pump cable (6), a sewage pump control line (12) and one end of a sewage pipe (8) are connected to a sewage pump (11); and the other ends are respectively connected to a distribution box circuit breaker (3), a cable-type float switch (13) and a sewage pipe (9); a steel wire rope (7) is fixed to the sewage pump (11) and placed at a certain height in the sewage chamber (1-3); and the upper end of the steel wire rope (7) is fixed to a fixed bracket (5). One end of the control line of the cable float switch (14) is connected to the sewage pump control line (12), and the other end is connected to the switch power supply (2) of the distribution box. After the connection is completed, the cable float switch (14) is placed in the sewage chamber (1-3), the position of the cable float switch (14) is adjusted, and the cable float switch fixing seat (13) is connected to the fixing bracket (5). When the liquid level in the sewage chamber (1-3) reaches the set high level, the cable float switch (14) is turned on, and the sewage pump (11) works to drain water. When the sewage liquid level reaches the set low level, the cable float switch (14) is turned off, and the sewage pump (11) stops working. This operation is repeated to realize the automatic discharge of sewage from the septic tank (1) to the municipal sewage pipe network (10).
