Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
The embodiment of the utility model provides a include ditch 6, level gauge 7, lift by crane facility 8, guide rail 5, main graticule mesh 3, block 4 and centralized control system 10.
A water inlet runner 1, a runner hole 9 and a water outlet runner 2 are arranged in front of and behind the water channel 6; the runner hole 9 is arranged between the water inlet runner 1 and the water outlet runner 2, and the water inlet runner 1 is communicated with the water outlet runner 2 through the runner hole 9. In this embodiment, two flow passage holes 9 are provided in front and rear.
Two guide rails 5 are fixedly arranged on the inner wall of the water channel 6, the two guide rails 5 are arranged in the front and back direction and are positioned between the water inlet flow passage 1 and the water outlet flow passage 2, the first guide rail 5 is close to the water inlet flow passage 1, and the second guide rail 5 is close to the water outlet flow passage 2. The two guide rails 5 are respectively positioned in front of the two runner holes 9.
The main grid 3 is arranged on the first guide rail 5 in a lifting and sliding way. The size of the water inlet 8 behind the main grid 3 is slightly smaller than that of the grid.
The blocking member 4 is detachably slidably mounted on the second guide rail 5. The blocking element 4 comprises a spare grid and a shutter, which are alternatively slidably mounted on the second guide 5.
The two hoisting facilities 8 are arranged on the edge of the ditch 6, and the two hoisting facilities 8 are respectively connected with the main grid 3 and the blocking piece 4.
The water inlet flow passage 1 and the water outlet flow passage 2 are respectively provided with a liquid level meter 7, and the liquid level meter 7 is connected with a centralized control system 10. The centralized control system 10 is a DCS system.
The observation hole 11 has been seted up at ditch 6 top before main graticule mesh 3 for when wasing or normally patrolling and examining, there is large-scale floater to check before main graticule mesh 3, and in time clear up.
The cooled circulating water flows to the water outlet flow channel 2 through the water inlet flow channel 1 and the main grid 3 and the water inlet holes 9, the filtered clean water is supplied to the heat exchange equipment again through the water pump suction pipeline, and at the moment, the blocking piece 4 is detached from the second guide rail 5. The level meter 7 that each runner 1 of intaking and 2 of going out water flow set up respectively sends liquid level data to centralized control system 10 for liquid level around real time monitoring main grid 3, and circulating water system is after using a period, receives air impurity and peripheral floater influence, and main grid 3 is dirty stifled, causes the grid front and back liquid level difference, and when both liquid level differences exceeded the setting value (like 0.3 m), centralized control system 10 reported to the police, the suggestion needs carried out main grid 3 and washs. Before the main grid 3 is cleaned, a spare grid is firstly installed at the position of a second guide rail 5 in a sliding mode by using a lifting facility 8, and then the main grid 3 to be cleaned is lifted by using the lifting facility 8; and moving the cleaned main grid 3 to the outside of the water channel 6 for cleaning by a high-pressure water gun. After cleaning, placing the grid in the original position, lifting the standby grid out of the water surface, and moving the standby grid to a warehouse for next cleaning. Thus, unfiltered circulating water can be prevented from entering the system.
