Problems solved by technology

[0002] The water supply device on the traditional building construction site mainly includes several parts such as the reservoir, the power frequency high-pressure water pump, the pipe network, and the return water. Connected to the water-demanding area, because the construction water does not always require the maximum amount in each section, therefore, it is necessary to install a "backwater" device next to the high-pressure water pump to discharge the excess water. One-half to one-third, the energy loss is relatively large, which is not conducive to energy saving and environmental protection
In actual construction, there will be insufficient water pressure and insufficient water volume. Special personnel are required to be responsible for the opening of the valve to meet the water requirements, which wastes labor costs, low reliability and lagging adjustment speed; during operation, due to frequent opening of the water pump And closing will produce water hammer phenomenon, water hammer phenomenon will have impact on water pipes and equipment, reduce the service life of equipment, increase the failure rate of equipment; moreover, the problem of dust in the construction site is relatively prominent at present, which has a great impact on the surrounding environment and operators Health hazards; therefore, it is also necessary to monitor the dust at the construction site in real time, and when the dust concentration is greater than or equal to the set value, start the water pump to automatically spray water to achieve dust reduction

Embodiment 1

[0040] In the present invention, the remote frequency conversion constant pressure pump set for construction can be specifically divided into a high-area pump set and a low-area pump set, which supply water to the high-altitude area and the low-altitude area respectively, and the water supply operation is divided, saving electric energy; specifically as figure 2As shown: the pump set in the high area includes a first frequency conversion water pump 3, two second frequency conversion water pumps 8 and a surge tank 4, the first frequency conversion water pump 3 is a frequency conversion water pump for high-altitude dust suppression, and the two second frequency conversion water pumps 8 are respectively The frequency conversion water pump for fire fighting and the frequency conversion water pump for maintenance, the water inlet end of the surge tank 4 is connected to the output ends of the first frequency conversion water pump 3 and the second frequency conversion water pump 8 thr...

Embodiment 2

[0045] In the present invention, the remote frequency conversion constant pressure pump group for construction includes a temperature sensor 71, a humidity sensor 72, an exhaust fan 73 and a warm fan 74, and the temperature sensor 71, the humidity sensor 72, the exhaust fan 73 and the warm fan 74 are all installed on the inner wall of the box structure 7 . When the temperature in the box structure 7 was high, the exhaust fan 73 was turned on to cool down, in case the temperature was too high and the equipment circuit was damaged; When the temperature is low, the parts in the equipment will freeze and crack, become hard and brittle, and are easily damaged.

[0046] Wherein, the temperature sensor 71 and the humidity sensor 72 are both electrically connected to a third controller (not shown in the figure), and the third controller is used to control the start and stop of the exhaust fan 73 and the heater fan 74 respectively. Specifically, the third controller is used to control...

Embodiment 3

[0048] In this application, the dust monitoring device 2 can not only realize dust monitoring, but also measure wind speed, wind direction, temperature, humidity, light intensity, carbon dioxide, PM2.5, PM10 and other environmental data; figure 2 As shown, the dust monitoring device 2 is mainly composed of a particle monitor (including monitor), environmental parameter collection device, data collection and transmission system, video monitoring system, background data processing system and information monitoring management platform. Specifically, light scattering monitors, 360° spherical cameras, meteorological five-parameter acquisition equipment and data transmission equipment are used to realize real-time, remote and automatic monitoring of particle concentration; data can be transmitted on smart mobile platforms, desktop PCs, etc. through network transmission. Multi-terminal access; the monitoring platform also has a variety of statistics and high-concentration alarm funct...
