Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a noise-reducing, energy-dissipating and splash-proof filler. Background Art

[0002] The high-level cooling tower adds a high-level water collection mechanism on the basis of the conventional tower. The high-level water collection mechanism mainly includes a water collection inclined plate 1, a water collection tank 2, a suspension rod 3, a lower hanging beam 4 and a splash-proof filler 5, wherein the upper part of the splash-proof filler 5 is placed on the water collection inclined plate 1, and its bottom end is placed on the lower hanging beam 4 (such as Figure 1 ), the splash-proof filler 5 has a length of about 1.8 meters and a thickness of about 100 mm.

[0003] At present, there are two types of splash-proof fillers: PVC triangular straight-through type and PP injection molding type. The PVC triangular straight-through type consists of several corrugated plates and flat plates spaced apart from each other, and the water passage formed between the corrugated plates and the flat plates is in the form of a triangular straight-through (such as Figure 2 ). The PVC triangle straight-through type has the following defects: (1) When the corrugated plate and the flat plate are bonded, they are in line-surface contact, which is prone to false adhesion and sliding, which is time-consuming and labor-intensive, and the bonding quality is unstable and easy to loosen; (2) The water flow channel is straight-through, which does not reduce the kinetic energy of falling water. Falling water directly passes through the water flow channel and impacts the water collecting inclined plate. When the water density is high, the splash-proof effect is limited, and there is no silencing function for the impact sound of water flow impacting the water collecting inclined plate. The PP injection molding type is injection molding by injection molding machinery (such as Figure 3 ), there are the following defects: (1) Due to the limitations of injection molding machinery and molds, only a two-stage splash-proof filler can be used. The length of a single splash-proof filler is about 900 mm. Since PP material is easily affected by temperature, when the two adjacent sections of the splash-proof filler are misaligned due to thermal expansion and contraction, the upper splash-proof filler will slip; (2) Since the bottom end of the splash-proof filler (i.e., the bottom end of the lower splash-proof filler) is placed on the lower hanging beam and is in a suspended state, and the area of ​​the lower splash-proof filler on the water collecting inclined plate is limited, the bottom end of the lower splash-proof filler is slightly affected by external force (such as hanging ice or water column impact), and the lower splash-proof filler is prone to instability and falls into the water collecting tank; (3) The water passage is also straight-through, resulting in limited splash-proof effect and no silencer function.

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a noise-reducing and energy-dissipating splash-proof filler with a simple structural design, good integrity, greatly improved splash-proof effect, and noise-reducing function.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a noise-reducing, energy-dissipating and splash-proof filler, including a corrugated plate and a fastening structure, the corrugated plate is composed of a plurality of pieces, which are distributed side by side in the transverse direction, and adjacent corrugated plates are arranged in a mirror-symmetrical manner, the contact surfaces of adjacent corrugated plates are bonded to form a plurality of water passages, and the fastening structure is arranged on the left and right sides of the corrugated plate to connect adjacent corrugated plates.

[0006] Furthermore, the water passage includes a splash-proof section, a primary energy dissipation section and a secondary energy dissipation section connected in sequence from top to bottom, the center line M of the splash-proof section is vertical, the center line N of the primary energy dissipation section is inclined, and the center line L of the secondary energy dissipation section is vertical.

[0007] Furthermore, the fastening structure includes a truncated cone and a conical cylinder. There are a plurality of truncated cones evenly installed on the left side of the corrugated plate along the longitudinal direction. There are a plurality of conical cylinders evenly installed on the right side of the corrugated plate along the longitudinal direction. The truncated cones and conical cylinders on adjacent corrugated plates correspond to each other, and the truncated cones are inserted into the conical cylinders.

[0008] Furthermore, the angle α between the center line L of the secondary energy dissipation section and the water receiving inclined plate is 45°.

[0009] Furthermore, the thickness of the corrugated plate is about 150 mm.

[0010] Furthermore, the cross section of the water passage is hexagonal.

[0011] Furthermore, it also includes a reinforcement structure, which includes a clamping column, a spring and an annular ridge. The clamping column is slidably installed in a radial groove opened in the middle of the frustum, and its outer end extends out of the notch of the radial groove. There are several clamping columns, which are evenly distributed along the circumference of the frustum. The spring is arranged in the radial groove, one end of the spring abuts against the inner end of the clamping column, and the other end abuts against the bottom of the radial groove. The annular ridge is installed in the middle of the outer circumferential wall of the cone cylinder, and an annular cavity is opened in the annular ridge, and the annular cavity is connected to the inner cavity of the cone cylinder.

[0012] Furthermore, the outer end of the clamping column is spherical.

DETAILED DESCRIPTION

[0030] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] Example 1

[0032] like Figure 4 and Figure 7 As shown, a noise reduction and energy dissipation splashproof filler includes a corrugated plate 100 and a fastening structure 200. The corrugated plate 100 is a plurality of pieces, which are arranged side by side in the horizontal direction, and the adjacent corrugated plates 100 are arranged in a mirror-symmetrical manner. The contact surfaces of the adjacent corrugated plates 100 are bonded to form a plurality of water passages 300. The fastening structure 200 is arranged on the left and right sides of the corrugated plate 100 to connect the adjacent corrugated plates 100. Through the arrangement of the fastening structure 200, the adjacent corrugated plates 100 are bonded to each other on the basis of the surface bonding, so that the splashproof filler forms a whole. Compared with the PVC triangle straight-through type, the bonding is convenient, labor-saving, and the bonding quality is more stable and not easy to loosen; compared with the PP injection molding type, there is no need for segmentation to avoid the splashproof filler from slipping and falling. Specifically, the corrugated plate 100 is made of PVC material; the cross section of the water passage 300 is hexagonal; the length of the splashproof filler can fully cover the water collecting inclined plate according to actual needs.

[0033] like Figure 4-Figure 6 , Figure 8As shown, the water passage 300 includes a splash-proof section 310, a primary energy dissipation section 320 and a secondary energy dissipation section 330 connected in sequence from top to bottom. The center line M of the splash-proof section 310 is in a vertical state, the center line N of the primary energy dissipation section 320 is in an inclined state, and the center line L of the secondary energy dissipation section 330 is in a vertical state. The water passage 300 adopts a three-stage type. Compared with the straight-through water passage 300, it avoids the direct impact of the water column on the front of the water receiving inclined plate, has a better splash-proof effect, and has energy dissipation and noise reduction functions. When the water column falls into the splash-proof section 310, the splash-proof section 310 prevents the water column from splashing. When the water column falls from the splash-proof section 310 to the inclined surface of the primary energy dissipation section 320, the inclined surface eliminates the potential energy of the falling water, and at the same time avoids the water column directly impacting the water receiving inclined plate and causing another splash. The falling water after energy dissipation impacts the water receiving inclined plate through the secondary energy dissipation section 330, further realizing energy dissipation. Specifically, the angle α between the center line L of the secondary energy dissipation section 330 and the water collecting inclined plate is 45°. It should be noted that since the water passage 300 adopts a three-stage type, if the thickness of the corrugated plate 100 continues to be designed as 100mm, the height of the splash-proof section 310 may be insufficient, affecting the splash-proof effect of the splash-proof section 310. Therefore, the thickness of the corrugated plate 100 in this application is designed to be about 150mm. At the same time, since this application does not adopt injection molding (the demoulding thickness is limited to about 100mm), it will not be limited by the demoulding thickness.

[0034] like Figure 4 , Figure 6 , Figure 7 and Fig. 9 As shown, the fastening structure 200 includes a truncated cone 210 and a conical cylinder 220. There are a plurality of truncated cones 210, which are evenly installed on the left side of the corrugated plate 100 along the longitudinal direction. There are a plurality of conical cylinders 220, which are evenly installed on the right side of the corrugated plate 100 along the longitudinal direction. The truncated cones 210 and conical cylinders 220 on adjacent corrugated plates 100 correspond to each other, and the truncated cones 210 are inserted into the conical cylinders 220. During installation, it is only necessary to insert the truncated cone 210 into the conical cylinder 220 on the right side of the adjacent corrugated plate 100, which is quick and convenient. In practical applications, the truncated cone 210 can also be replaced by the conical cylinder 220.

[0035] Example 2

[0036] This embodiment adds a reinforcement structure 400 on the basis of Embodiment 1. The arrangement of the reinforcement structure 400 further reinforces the connection between adjacent corrugated plates 100 on the basis of the fastened connection, thereby further improving the bonding quality of adjacent corrugated plates 100.

[0037] like Fig. 9 and Fig.10As shown, the reinforcement structure 400 includes a clamping column 410, a spring 420 and an annular ridge 430. The clamping column 410 is slidably installed in a radial groove 211 opened in the middle of the frustum 210, and its outer end extends out of the notch of the radial groove 211. There are several clamping columns 410, which are evenly distributed along the circumference of the frustum 210. The spring 420 is arranged in the radial groove 211, one end of the spring 420 abuts against the inner end of the clamping column 410, and the other end abuts against the bottom of the radial groove 211. The annular ridge 430 is installed in the middle of the outer circumferential wall of the cone 220, and an annular cavity 431 is opened in the annular ridge 430, and the annular cavity 431 is connected to the inner cavity of the cone 220. During the process of inserting the truncated cone 210 into the right side cone 220 of the adjacent corrugated plate 100, the outer end of the clamping column 410 compresses the spring 420 and retracts into the radial groove 211 under the resistance of the inner wall of the cone 220. When the truncated cone 210 is inserted into place, the spring 420 pushes the outer end of the clamping column 410 out of the radial groove 211 and into the annular cavity 431, forming an axial limit. Specifically, the outer end of the clamping column 410 is spherical.

[0038] like Fig.10 As shown, the inner end outer peripheral wall of the clamping column 410 is evenly provided with a plurality of stop blocks 411 along the circumferential direction, and the middle inner wall of the radial groove 211 is provided with a plurality of stop grooves 2111 along the circumferential direction. The stop block 411 extends from the end of the clamping column 410 to the stop groove 2111 and slidably cooperates with the stop groove 2111. The cooperation between the stop block 411 and the stop groove 2111 limits the position of the clamping column 410 in the radial groove 211, and prevents the clamping column 410 from overextending.

[0039] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
