Abstract

The falling water noise reducing floating frame includes grating frame and hollow circular floating pipes, which are arranged parallelly or in grating form and set below the grating frame. Because change the flotation pontoon into cavity circle and float the pipe, make the buoyancy of whole floating frame more even, and the grid frame is fixed on hollow circular superficial pipe, it is good not only the levelness to install falling into water on the grid frame and fall the board of making an uproar, the working angle that falls into water and fall the board of making an uproar can obtain guaranteeing, the drop of water of whereabouts drips on hollow circular superficial pipe in addition, can the amortization landing, can not produce the secondary noise, fall into water simultaneously and fall the board of making an uproar and the distance between the surface of water is stable, can full play fall the effect of making an uproar of falling into.

Description

Floating pipe type falling water noise reducing support frame

Technical field

The utility model relates to the cooling tower falling water noise reducing device that the power plant uses, and relates in particular to the bracing frame of falling water noise reducing plate.

Background technology

In the cooling tower in power plant, all must use the falling water noise reducing device, what noise reduction was best at present is exactly " the cooling tower falling water noise reducing device " of the applicant in the calendar year 2001 application, the patent No. is 01230431.X, it comprises falling water noise reducing plate and float-type bracing frame, the falling water noise reducing plate is the cellular noise reducing plate that the pipe oblique arrangement of both ends open constitutes, this denoiser has adopted the inclined-plane principle of noise reduction, making falls into water contacts with the inclined-plane of cellular board, its noise reduction is more satisfactory, and bracing frame is the float-type bracing frame.This falling water noise reducing device has become the first-selected articles for use that current power plant cooling tower noise reduction is transformed, but this product also has certain defective in actual use, wherein the design of float-type bracing frame is reasonable inadequately, grill frame is fixed on a plurality of fiberglass floating drums, because the fiberglass floating drum is made and is varied, the buoyancy that causes each floating drum to produce is not of uniform size, after bracing frame is put into the pond, the noise reducing plate difficulty reaches the requirement of predeterminated level degree, in actual use, the operating angle of noise reducing plate can't guarantee, every floating drum resembles a drum on the other hand, the globule that falls drips to be beaten on the end face of floating drum, can produce bigger noise, so the float-type bracing frame is difficult to make the best noise reduction of falling water noise reducing plate performance.

Summary of the invention

Goal of the invention of the present utility model provides a kind of floating pipe type falling water noise reducing support frame, it can effectively overcome the deficiency that the float-type bracing frame exists, can not only eliminate the globule and drip the secondary noise of playing the floating drum generation, and can guarantee the correct setting angle of falling water noise reducing plate, give full play to the noise reduction of falling water noise reducing plate.

Technical solution adopted in the utility model is:

Described floating pipe falling water noise reducing support frame, it is characterized in that: it comprises grill frame and floating shelf, and grill frame is fixed on the floating shelf, and described floating shelf is made up of the floating pipe of some hollows.

Described floating pipe falling water noise reducing support frame, described grill frame is fixed on the floating shelf by restraint zone.

Described floating pipe falling water noise reducing support frame, described floating shelf is combined into one by the parallel interval arrangement mode by the floating pipe of the hollow of some circles.

Described floating pipe falling water noise reducing support frame, described floating shelf is integral by grill-shaped mode permutation and combination by the floating pipe of the hollow of some circles.

Owing to change floating drum into hollow floating pipe, the buoyancy of floating shelf is more even, and grill frame is fixed on the floating shelf, not only levelness is good to be installed in falling water noise reducing plate on the grill frame, and the operating angle of falling water noise reducing plate can be guaranteed, and the globule that falls drops on the floating pipe of circular hollow, can noise reduction land, can not produce the secondary noise, the stable distance between the falling water noise reducing plate and the water surface simultaneously can be given full play to the noise reduction of falling water noise reducing plate.

Description of drawings

Fig. 1 is the structural representation that falling water noise reducing device of the present utility model is housed;

Fig. 2, Fig. 3 are schematic diagram of the present utility model; Fig. 3 is the vertical view of Fig. 2;

Among the figure: the 1-floating shelf; The 2-grill frame; The 3-restraint zone; The floating pipe of 4-hollow; 5-falling water noise reducing plate;

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is elaborated:

Example 1: described floating pipe falling water noise reducing support frame, shown in accompanying

drawing

2,3, it is made up of grill frame 2, restraint zone 3 and floating shelf 1, described floating shelf 1 is arranged in a combination by the parallel interval mode by the floating pipe of the hollow of some circles 4, the floating pipe 4 of the hollow of some circles is evenly distributed in the lower end of grill frame 2, and grill frame 2 is fixed on the floating pipe 4 of circular hollow by restraint zone 3.

Example 2: go up in the example, described floating shelf 1 is arranged by grill-shaped by the floating pipe 4 of the hollow of some circles, and grill frame 2 is fixed on the floating shelf 1 by restraint zone 3.

Its using method is as follows: falling water noise reducing plate 5 is placed on floating shelf 1 gets final product, as shown in Figure 1.
