An energy-saving high-rise building construction temporary automatic water supply simple combined system

technical field

The utility model relates to the field of building construction facilities, in particular to an energy-saving simple combination system for temporary automatic water supply in high-rise building construction.

Background technique

In the construction of high-rise buildings, in order to solve the water problem of the floors on site, it is generally necessary to set up a reservoir and then use a pressurized water pump to directly supply water to the floors. We always install a pressurized pump on the water pipe, or add a set of pipeline pumps to directly send electricity water supply. When this kind of general device does not use water, it is impossible for workers to turn off the water from dozens of floors up and down, but to directly turn off the faucet, and at this time the water pump is still running continuously to pump water, resulting in a large amount of water and electricity. waste; moreover, the water pump keeps running, which increases the pressure of the water pipes, which can easily cause damage to the water pumps, motors, water pipes and other facilities; in addition, when the workers are off duty, the water pumps are often turned off, and the water supply to the floor is stopped. When emergencies (such as fires) require timely water, it is difficult for general devices to meet the requirements. In order to overcome these shortcomings and difficulties, it is necessary to design a set of innovative devices on the basis of general devices.

Detailed ways

As shown in Figure 1, when the utility model was implemented, it included a reservoir 7, a water pump 4, a contact pressure gauge 3, a check valve 5, an automatic water supply control box 6, and a water pump motor (its position is the same as that of the water pump 4 in Fig. 1 ). The position overlaps, and the water pump motor is indicated with reference sign M in Fig. 2) and the water supply pipe. The water supply pipe includes a main water pipe 2 and a floor water distribution pipe 9 , the main water pipe 2 is connected to the reservoir 7 and the floor water distribution pipe 9 , and the floor water distribution pipe 9 is connected to the water tap 1 . The water pump 4, the check valve 5 and the contact pressure gauge 3 are arranged on the main water pipe 2, wherein the water pump 4 is arranged near the reservoir 7, and the check valve 5 is arranged on the water pump 4 and the contact pressure gauge. Between Table 3. Comprise an automatic water supply control circuit in the automatic water supply control box 6. The normally closed contact of contact pressure gauge 3 links to each other with the automatic water supply control circuit in the automatic water supply control box 6 by electric wire 10, and the automatic water supply control circuit in the automatic water supply control box 6 links to each other with the water pump motor by cable 8.

As shown in Figure 1 and Figure 2, the normally closed contact Y of the contact pressure gauge 3 is connected in series with the power supply circuit of the attraction coil of the AC contactor Km through the wire 10; The three moving contacts are respectively connected in series through the cables 8 to the three AC phase lines A, B, and C that supply power to the water pump motor. In the power supply circuit of the attracting coil of the AC contactor Km, there is also a dynamic breaker contact of the thermal relay RJ in series, and the thermal sensitive element of the thermal relay RJ is connected in series in the AC phase line for powering the water pump motor.
