Problems solved by technology

[0006] In order to solve the problem in the prior art that when the dirt accumulated on the net and in front of the trash net reaches a certain amount, the dirt will easily block the trash net, resulting in a water level difference on both sides of the trash net. When the water level difference reaches a certain value, it may As a result, the trash net is damaged under the pressure of the water on both sides, and the trash blocking effect is lost. A large amount of dirt pours into the power plant to block equipment such as grids and drum nets, causing the power plant's generator set to trip and stop, and the maintenance cost is high. Problem, the embodiment of the present invention provides a sewage blocking device for open water intake channels

Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0065] Such as figure 1 shown, combined with figure 2 To illustrate, the embodiment of the present invention provides a kind of sewage intercepting device for open water intake channel. In the embodiment of the present invention, the application of the open water intake channel for power plant to the open channel for water intake is used as an example for illustration. : two land piers 1, main mesh wire rope 2, main mesh 3, two side mesh nylon ropes 4, two fusible cables 6 and two sections of side mesh 5;

[0066] The two land piers 1 are respectively fixed on the embankment slopes 200 on both sides of the water intake open channel mouth, and both are located above the high water level;

[0067] Both ends of the main mesh wire rope ...

Abstract

The invention discloses a trash holding device of a water intaking open channel opening, and belongs to the field of circulating water intaking and filtering. The trash holding device comprises two land area abutments, a main net steel wire rope, a main net, two side net nylon ropes, two fusible cables and two side nets. When the waterhead of the two sides of the main net is large due to too much dirt accumulated on the trash holding device of the water intaking open channel opening and in front of the trash holding device, the fusible cables are fused, the two side nets are burst open, water passes through the two side nets, the waterhead of the two sides of the main net is reduced, and it is guaranteed that the main net is not damaged; most dirt accumulated on the trash holding device and in front of the trash holding device is held up by the main net, and therefore the situation that a large amount of dirt swarms into a power plant to block equipment such as a grating and a drum net, and consequently a generator net of the power plant is shut down is avoided; and the maintenance cost of the trash holding device is low.

Description

technical field [0001] The invention relates to the field of water intake and filtration of circulating water, in particular to a sewage blocking device at the mouth of an open water intake channel. Background technique [0002] The circulating water intake facilities of the Binhai Power Plant are built in the area near the coastline, and open channels are mostly used for water intake. Due to engineering floating objects or marine organisms mixed in the seawater, it is easy to block the grids and drum nets of the power plant, causing the generator sets of the power plant to trip. , so it is necessary to set up a trash stop device at the mouth of the open water intake channel to intercept and remove engineering floating objects or marine organisms mixed in the seawater. [0003] The current trash blocking device includes a first fixed pier, a second fixed pier, a cable and a trash net. The first fixed pier and the second fixed pier are respectively arranged on the dike slopes...
