Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, and in particular to a noise reduction and sound insulation barrier for cooling towers. Background Technology

[0002] A cooling tower is a device used to cool water carrying heat for reuse. It is widely used in air conditioning systems of industrial production and large buildings. It achieves cooling by spraying hot water into fine droplets or forming a water film, utilizing the direct contact between the air and water to remove heat.

[0003] During operation, cooling towers generate noise from fan rotation, water flow, and vibration, all of which impact the factory environment. Currently, to mitigate this noise pollution, sound barriers are installed externally. These barriers consist of a frame and aluminum alloy plates mounted on it. While simple in structure and effective in reducing noise to some extent, their noise reduction effect is limited. Furthermore, installation often employs welding and riveting, which offers greater flexibility on-site but results in a long construction period. Utility Model Content

[0004] This utility model provides a noise reduction and sound insulation barrier for cooling towers, which solves the shortcomings of the prior art, addresses the problems of poor sound insulation effect and long installation and construction period, and has strong practicality.

[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A noise reduction and sound insulation barrier for cooling towers includes four identical sound insulation units, which are fixed to the ground to form a rectangular frame enclosure. Alternatively, three sound insulation units can be used to form a triangular enclosure. The enclosure structure is set according to the on-site construction conditions.

[0006] The sound insulation unit includes a pair of uprights, with connectors at the lower ends of the uprights. A mounting plate is welded to the lower end of the connector, and the mounting plate is bolted to the foundation. Multiple rectangular tubes are installed between the uprights, their lengths perpendicular to the lengths of the uprights. Wall panels are mounted on the rectangular tubes with screws. This design facilitates easy disassembly and installation of the uprights and connectors, preventing excessive height of the uprights and thus reducing the risk of accidents during construction. Multiple sound-absorbing components are located on the front of the wall panels. Concave components are located at both ends between adjacent sound-absorbing components. The outer ends of the concave components are bent outwards to create limiting protrusions. The inner wall of the limiting protrusions acts on the outer wall of the sound-absorbing components, and the concave components are mounted to the uprights with screws. The combined effect of the sound-absorbing components and the wall panels further weakens the energy of noise propagation, thereby achieving noise reduction. Furthermore, the concave components facilitate the fixing of the sound-absorbing components, and the resulting stability is strong.

[0007] Furthermore, the connector has multiple protruding plates on its outer periphery, which are embedded in the inner wall of the upright. These protruding plates enhance the structural strength of the connector and improve the connection between the connector and the upright.

[0008] Furthermore, the connector is secured by a first bolt and a second bolt, with the axial direction of the first bolt perpendicular to the axial direction of the second bolt. This dual-directional positioning enhances the fixing effect.

[0009] Furthermore, the interior of the wall panel is hollow and filled with sound-absorbing cotton. The sound-absorbing cotton can weaken the energy of sound propagation, thereby achieving the purpose of noise reduction.

[0010] Furthermore, the sound-absorbing component has a hollow internal structure and is filled with sound-absorbing columns made of cotton material. The inner wall of the sound-absorbing columns has multiple holes. The two ends of the sound-absorbing component are fixed with end caps by pins. The sound insulation effect is improved by filling the sound-absorbing component with sound-absorbing columns. Secondly, the sound-absorbing component can also be vacuumed to reduce noise by reducing the sound transmission medium.

[0011] Furthermore, to facilitate the installation and fixation of the rectangular tubes, which serve to strengthen the connection between the uprights and improve the rigidity of the sound barrier, concave clips are installed at both ends of the rectangular tubes using multiple third bolts. L-shaped pieces are welded to the outer ends of the concave clips, and these L-shaped pieces are fastened to the uprights. The L-shaped pieces have slots, and a retaining plate is welded to the outer wall of the upright, passing through the slot.

[0012] Furthermore, to facilitate the installation of the rectangular tube, a locking protrusion is formed on the clamping plate, a connecting post is welded to the L-shaped piece, a pull plate passes through the connecting post, a connecting pin is provided on the outer end of the pull plate, a rotating sleeve is rotatably mounted on the connecting pin, a rectangular hole is opened at one end of the rotating sleeve, the locking protrusion passes through the rectangular hole, a groove is opened on the outer end of the rotating sleeve, the pull plate passes through the groove, and a pair of inner insert plates are formed on the outer end of the pull plate. When the locking protrusion passes through the rectangular hole, the inner insert plates are inserted into the connecting post. On the top, rotating protruding rods are welded to the upper and lower sides of the connecting column. A concave rotating plate is rotatably mounted on the rotating protruding rod. An outer support rod is mounted on the concave rotating plate. An outer protruding plate is vertically formed on the outer end of the pull plate. An outer support U-groove is opened on the outer end of the outer protruding plate. The outer support rod passes through the outer support U-groove. An inner top screw is threaded to the other end of the concave rotating plate. An end cap is provided on the outer end of the inner top screw. An inner top locking block is rotatably mounted on the inner end of the inner top screw. A limit socket is opened at the end of the pull plate. The inner top locking block is inserted into the limit socket.

[0013] The advantages of the above technical solution are: This invention can significantly improve the sound insulation and noise reduction effect, and facilitate on-site installation and construction, thereby shortening the construction cycle. Attached Figure Description

[0019] Figure 5 A magnified view of point B is shown. Detailed Implementation

[0020] like Figures 1-5 As shown, a noise reduction and sound insulation barrier for cooling towers includes four identical sound insulation units, which are fixed to the ground to form a rectangular frame enclosure structure.

[0021] The sound insulation unit includes a pair of uprights 1. A connector 2 passes through the lower end of each upright 1. A mounting plate 22 is welded to the lower end of each connector 2. The mounting plate 22 is bolted to the foundation. Multiple protruding plates 20 are provided on the outer periphery of the connector 2, and these protruding plates 20 are embedded in the inner wall of the upright 1. The connector 2 is connected by a first bolt 21 and a second bolt 23, with the axial direction of the first bolt 21 perpendicular to the axial direction of the second bolt 23.

[0022] Multiple rectangular tubes 5 are provided between the uprights 1. The length direction of the rectangular tubes 5 is perpendicular to the length direction of the uprights 1. A wall panel 3 is installed on the rectangular tubes 5 by screws. The wall panel 3 has a hollow structure and is filled with sound-absorbing cotton.

[0023] The front side of the wall panel 3 is provided with multiple sound-absorbing components 4. The sound-absorbing components 4 have a hollow internal structure and are filled with sound-absorbing columns. The sound-absorbing columns are made of cotton material and have multiple holes on their inner walls. The two ends of the sound-absorbing components 4 are fixed with end caps by pins. The two ends of two adjacent sound-absorbing components 4 are respectively provided with concave components 40. The outer end of the concave component 40 is bent outward to a limiting protrusion 41. The inner wall of the limiting protrusion 41 acts on the outer wall of the sound-absorbing component 4, and the concave component 40 is installed on the upright 1 by screws.

[0024] When the component provided in this embodiment reduces noise, the noise generated by the cooling tower spreads outwards. During the propagation process, it is first weakened by the energy of the silencing component 4 and its internal silencing column, thereby reducing the ability of the noise to propagate outwards. Then, the noise will pass through the wall panel 3 and be further blocked by the wall panel 3 and its internal silencing cotton, thereby further significantly reducing the noise level.

[0025] In this embodiment, during installation, the connector 2 is first installed on the foundation using bolts, then the upright 1 is inserted into the upright 1, and the two are connected and fixed using the first bolt 21 and the second bolt 23. After fixing, the rectangular tube 5 is fixed between the uprights using bolts, then the wall panel 3 is fixed to the rectangular tube 5 using self-tapping screws, and finally the sound-absorbing component 4 is installed using the concave part 40.

[0026] In some embodiments, the two ends of the rectangular tube 5 are fitted with concave clips 50 by multiple third bolts 51. An L-shaped piece 52 is welded to the outer end of the concave clip 50. The L-shaped piece 52 is fastened to the upright 1. A slot 53 is opened on the L-shaped piece 52. A clamping plate 73 is welded to the outer wall of the upright 1. The clamping plate 73 passes through the slot 53. The card plate 73 has a carding protrusion 74 formed on it. A connecting post 6 is welded onto the L-shaped part 52. A pull plate 60 passes through the connecting post 6. A connecting pin 70 is provided on the outer end of the pull plate 60. A rotating sleeve plate 71 is rotatably mounted on the connecting pin 70. A rectangular hole is opened at one end of the rotating sleeve plate 71, and the carding protrusion 74 passes through the rectangular hole. A groove is opened on the outer end of the rotating sleeve plate 71, and the pull plate 60 passes through the groove. A pair of inner insert plates 72 are formed on the outer end of the pull plate 60. When the carding protrusion 74 passes through the rectangular hole, the inner insert plates 72 are inserted into the connecting post 6. The upper and lower sides of the connecting post 6 are welded... There is a rotating convex rod 63, and a concave rotating plate 64 is rotatably mounted on the rotating convex rod 63. An outer support rod 65 is mounted on the concave rotating plate 64. An outer convex plate 61 is vertically formed on the outer end of the pull plate 60. An outer support U-groove 62 is opened on the outer end of the outer convex plate 61. The outer support rod 65 passes through the outer support U-groove 62. The other end of the concave rotating plate 64 is connected to an inner top screw rod 67 by a thread. An end cap 68 is provided on the outer end of the inner top screw rod 67. An inner top locking block 69 is rotatably mounted on the inner end of the inner top screw rod 67. A limit socket is opened at the end of the pull plate 60. The inner top locking block 69 is inserted into the limit socket.

[0027] Optionally, when fixing the rectangular tube 5 using the above method, the operator installs concave clips 50 at both ends of the rectangular tube 5 using multiple third bolts 51, and then fastens the L-shaped piece 52 onto the upright 1. After fastening, the clip plate 73 needs to be inserted into the slot 53. Then, the concave rotating plate 64 is rotated. When it rotates, the outer support rod 65 acts on the outer support U-groove 62, thereby causing the pull plate 60 to move inward. At the same time, the clip protrusion 74 is inserted into the rectangular hole, and the inner insert plate 72 is inserted into the connecting column 6. Then, by screwing the inner top screw 67, the inner top clip 69 is inserted into the limiting socket to limit the rotation of the concave rotating plate 64.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
