Device for pumping drainage monitoring and alarming of underground pump house

Abstract

The invention discloses a device for pumping drainage monitoring and alarming of an underground pump house. The device comprises a liquid level monitoring device, and a circuit overload monitoring device. The liquid level monitoring device comprises a floating ball, a support and an electric sensor, wherein the electric sensor is equipped with a relay coil, installed on the support to form high-level and low-level touch point switches, and electrically connected to the circuit overload monitoring device; and the support is installed on the floating ball. The circuit overload monitoring device comprises an electric control box, wherein a main loop and a control loop are installed inside the electric control box; and a first relay, a second relay and a contact device are disposed on the main loop and the control loop. A first contact point of the contact device is disposed in a power source circuit of a three-phase circuit; and a second contact point and a coil of the contact device are disposed in the main loop. The device disclosed by the invention can effectively solve the problem of accumulated water overflowing caused by monitoring lack of a liquid pumping device can be solved effectively and can enhance running control capability.

Description

technical field [0001] The invention relates to pond water treatment equipment, more specifically, to a monitoring pumping and alarming device for an underground pump room. Background technique [0002] Underground space is a common building. Due to the needs of building functions and the infiltration of groundwater, a pump room is generally installed in the underground space of the building for pumping or transporting accumulated water. [0003] The accumulated water in the underground space is usually divided into clean water, reclaimed water and sewage according to the source of water quality and cleanliness. Among them, clean water refers to water with high cleanliness and can be used for daily life (such as tap water, etc.), and reclaimed water refers to cleanliness Water that is lower than clean water but higher than sewage, and can be used for cleaning, irrigation, and industrial cooling (such as accumulated rainwater and purified industrial water, etc.). Water that ...

AI Technical Summary

Problems solved by technology

[0009] 1. Monitoring failure: Since the hot extrusion cooling water contains metal impurities, grease, etc., it is easy to adhere between the floating ball and the limit contact, resulting in a decrease in the sensitivity of the liquid level monitoring, or even failure, and the actual height of the liquid level cannot be real Effectively reflect to the liquid pump, sometimes the liquid level is at a high level, but the liquid pump fails to start due to failure to receive the monitoring signal, resulting in overflow of cooling water

[0010] 2. Unable to detect the operation of the water pump: the existing device can only detect the level of the accumulated water, but cannot monitor the operation status of the water pump. Functional limitations cannot be displayed and alarmed in time, resulting in overflow of cooling water

[0011] 3. The structure of double floating balls is relatively cumbersome: two floating balls are installed in a water recovery station with an area of ​​less than 1 square meter, and the centralized installation of two sets of signal lines, contact brackets, water pumps, etc. is relatively cramped, and daily maintenance is also difficult. inconvenient

[0012] Therefore, at present, there are certain deficiencies in the online operation monitoring and timely fault alarm of the hot extrusion underground pump room pumping device. Once the water in the basement pump room overflows, it will affect the adjacent equipment, resulting in the expansion of equipment failure. At the same time, the flooding of the underground pump room will affect the entire working environment, which will bring a lot of inconvenience to the employees who enter the pump room for disposal operations, and there are certain safety hazards
