Description

Technical Field

[0001] This utility model relates to the field of cooling tower silencing technology, specifically a cooling tower silencer sliding device. Background Technology

[0002] Silencers are usually installed at the air inlet of power plant mechanical cooling towers to reduce noise. However, the installation of silencers can cause inconvenience for customers during maintenance. On the other hand, the installation of soundproof doors can affect the cooling and ventilation effect. Therefore, a cooling tower silencer sliding device is proposed to facilitate the formation of a maintenance passage at the air inlet of the power plant mechanical cooling tower when maintenance is required. Utility Model Content

[0003] The purpose of this utility model is to provide a cooling tower silencer sliding device to solve the problem mentioned in the background art that the installation of silencers at the air inlet of power plant mechanical cooling towers causes inconvenience for customers during maintenance.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cooling tower silencer sliding device includes brackets evenly spaced at the air inlet of a power plant mechanical cooling tower. A silencer unit is installed on each bracket. A slider is fixedly installed on the top of the bracket, and a slide rail is slidably connected within the slider. The slide rail is fixedly installed on the inner top of the air inlet of the power plant mechanical cooling tower. A directional wheel is rotatably installed at the bottom of the bracket. The directional wheels are in the same direction and can roll along the sliding direction of the slider and slide rail. The directional wheel rolls at the bottom of the air inlet of the power plant mechanical cooling tower. Fixed connecting rods are fixedly connected to the outermost brackets and are fixedly connected to the side wall of the air inlet of the power plant mechanical cooling tower. Two fixed-length connecting rods are arranged parallel between the two middle brackets. The maximum opening length of the fixed-length connecting rods is equal to that of the hinge mechanism. The two ends of the fixed-length connecting rods are fixedly installed to the corresponding brackets by fixing bolts. Circular holes for the fixing bolts to pass through are opened at both ends of the fixed-length connecting rods. Threaded holes for the threaded connection of the fixing bolts are opened on the brackets. A hinge mechanism is provided between the brackets between the middle brackets and the edge brackets.

[0006] As a further embodiment of this utility model: the hinge mechanism includes a first link and a second link, with the ends of the first link and the second link being hinged to corresponding supports respectively.

[0007] As a further embodiment of this utility model: the upper end of the first connecting rod is fixedly connected to a first connecting plate, and the upper end of the second connecting rod is fixedly connected to a second connecting plate. The second connecting plate and the first connecting plate are concentrically arranged and are rotatably installed by a pin.

[0008] As a further solution of this utility model: a limiting pin is fixedly connected to the eccentric part of the first connecting plate, and an arc-shaped limiting groove is opened on the second connecting plate corresponding to the limiting pin, and the arc-shaped limiting groove is concentrically set with the pin shaft.

[0009] As a further embodiment of this utility model: the tail end of the arc-shaped limiting groove of the second connecting plate is provided with a limiting protrusion, the limiting protrusion corresponds to and is adapted to the limiting pin, the limiting protrusion is slidably connected in the U-shaped seat, and a spring is fixedly connected between the U-shaped seat and the limiting protrusion, and the U-shaped seat is fixedly connected to the second connecting plate.

[0010] As a further improvement of this utility model: the opening of the U-shaped seat is symmetrically and fixedly connected with a limiting block, and a limiting guide groove is opened on the limiting card protrusion corresponding to the limiting block. The limiting block is slidably connected in the limiting guide groove. Through the cooperation of the limiting block and the limiting guide groove, the limiting card protrusion is restricted in the U-shaped seat, so as to prevent the limiting card protrusion from slipping off.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the slider slides on the slide rail, and the directional wheel can roll, thereby allowing the bracket to move. In conjunction with the hinge mechanism, adjacent brackets can form a linkage. The fixed-length connecting rod fixes the two middle brackets to each other through the fixing bolts. Thus, by disassembling the fixed-length connecting rod, the bracket can be slid to both sides, making the middle position open up a passage, thereby facilitating the entry and exit of personnel for maintenance.

[0013] 2. In this utility model, the first and second connecting rods rotate through the first connecting plate, the second connecting plate, and the pin, so that the distance between the ends of the first and second connecting rods can change with the movement of the bracket. The rotation angle of the first and second connecting plates is limited by the limiting pin and the arc-shaped limiting groove, thereby controlling the limit distance between the opening ends of the first and second connecting rods and preventing the remaining brackets from moving after the bracket is fully unfolded and fixed by the fixed-length connecting rod.

[0014] 3. This utility model uses a U-shaped seat and a spring to push the limiting card protrusion outward, while the limiting block and limiting guide groove limit the limiting card protrusion. This allows the limiting card protrusion to elastically insert into the arc-shaped limiting groove. When the bracket is fully closed, the limiting card protrusion can limit the limiting pin, preventing the bracket from moving without pushing and causing the channel to close, thus affecting passage.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 4 In this embodiment of the utility model, a cooling tower silencer sliding device includes brackets 2 evenly spaced at the air inlet 1 of a power plant mechanical cooling tower. A silencer unit 3 is installed on the brackets 2. A slider 4 is fixedly installed on the top of the brackets 2, and a slide rail 5 is slidably connected within the sliders 4. The slide rail 5 is fixedly installed on the inner top of the air inlet 1 of the power plant mechanical cooling tower. A directional wheel 6 is rotatably installed at the bottom of the brackets 2. The directional wheels 6 are in the same direction and can roll along the sliding direction of the slider 4 and the slide rail 5. The directional wheels 6 roll at the bottom of the air inlet 1 of the power plant mechanical cooling tower. The outermost bracket... Each of the two supports 2 is fixedly connected with a fixed connecting rod 7, which is fixedly connected to the side wall of the air inlet 1 of the power plant cooling tower. Two fixed-length connecting rods 8 are arranged in parallel between the two middle supports 2. The maximum opening length of the fixed-length connecting rods 8 is equal to that of the hinge mechanism 10. The two ends of the fixed-length connecting rods 8 are fixedly installed to the corresponding supports 2 by fixing bolts 9. The two ends of the fixed-length connecting rods 8 are provided with round holes for the fixing bolts 9 to pass through. The supports 2 are provided with threaded holes for the threaded connection of the fixing bolts 9. The hinge mechanism 10 is provided between the supports 2 between the middle support 2 and the edge support 2.

[0022] The slider 4 slides on the slide rail 5, and the directional wheel 6 can roll, so that the bracket 2 can move. In conjunction with the hinge mechanism 10, the adjacent brackets 2 can be linked together. The fixed-length connecting rod 8 fixes the two middle brackets 2 to each other through the fixing bolt 9. Thus, by disassembling the fixed-length connecting rod 8, the bracket 2 can be slid to both sides, so that the middle position is cleared, which facilitates the staff to enter and exit for maintenance.

[0023] The hinge mechanism 10 includes a first link 11 and a second link 12, with the ends of the first link 11 and the second link 12 being hinged to the corresponding brackets 2 respectively.

[0024] The upper end of the first connecting rod 11 is fixedly connected to the first connecting plate 13, and the upper end of the second connecting rod 12 is fixedly connected to the second connecting plate 14. The second connecting plate 14 and the first connecting plate 13 are concentrically arranged and are installed by rotating the pin.

[0025] A limiting pin 15 is fixedly connected to the eccentric part of the first connecting plate 13, and an arc-shaped limiting groove 16 is opened on the second connecting plate 14 corresponding to the limiting pin 15. The arc-shaped limiting groove 16 is concentrically set with the pin shaft.

[0026] The first connecting rod 11 and the second connecting rod 12 rotate through the first connecting plate 13, the second connecting plate 14 and the pin, so that the distance between the ends of the first connecting rod 11 and the second connecting rod 12 can change with the movement of the bracket 2. The rotation angle of the first connecting plate 13 and the second connecting plate 14 is limited by the limiting pin 15 and the arc-shaped limiting groove 16, thereby controlling the limit distance between the ends of the first connecting rod 11 and the second connecting rod 12 when they are opened, and preventing the remaining brackets 2 from still moving after the bracket 2 is fully unfolded and fixed by the fixed-length connecting rod 8.

[0027] The second connecting plate 14 is provided with a limiting protrusion 17 at the tail end of the arc-shaped limiting groove 16. The limiting protrusion 17 corresponds to and is adapted to the limiting pin 15. The limiting protrusion 17 is slidably connected in the U-shaped seat 18. A spring 19 is fixedly connected between the U-shaped seat 18 and the limiting protrusion 17. The U-shaped seat 18 is fixedly connected to the second connecting plate 14.

[0028] A limiting block 20 is symmetrically fixedly connected to the opening of the U-shaped seat 18. A limiting guide groove 21 is opened on the limiting protrusion 17 corresponding to the limiting block 20. The limiting block 20 is slidably connected in the limiting guide groove 21. Through the cooperation of the limiting block 20 and the limiting guide groove 21, the limiting protrusion 17 is restricted in the U-shaped seat 18, so as to prevent the limiting protrusion 17 from slipping off.

[0029] The U-shaped seat 18, in conjunction with the spring 19, pushes the limiting protrusion 17 outward. At the same time, the limiting block 20 and the limiting guide groove 21 limit the limiting protrusion 17, allowing the limiting protrusion 17 to elastically insert into the arc-shaped limiting groove 16. When the bracket 2 is fully closed, the limiting protrusion 17 can limit the limiting pin 15, preventing the bracket 2 from moving without being pushed, causing the channel to close and affecting passage.

[0030] The working principle of this utility model is as follows:

[0031] When opening, loosen the fixing bolt 9 and disassemble the fixed-length connecting rod 8. At this time, push the middle bracket 2 to both sides so that the brackets 2 come closer together, forming a channel in the middle. When the brackets 2 come closer together, the first connecting rod 11 and the second connecting rod 12 form a folding effect. At this time, the first connecting plate 13 and the second connecting plate 14 rotate relative to each other, and the limiting pin 15 moves along the arc-shaped limiting groove 16 until the limiting protrusion 17 is pressed and moves to the end of the arc-shaped limiting groove 16. Under the action of the spring 19, the limiting protrusion 17 pops out along the U-shaped seat 18, thereby limiting the limiting pin 15 through the limiting protrusion 17, so that the brackets 2 are limited to the close-up state.

[0032] When closed, the middle support 2 is brought together, and the adjacent supports 2 are pulled away from each other. The first connecting rod 11 and the second connecting rod 12 are opened, and the first connecting plate 13 and the second connecting plate 14 rotate relative to each other. The limiting pin 15 moves along the arc-shaped limiting groove 16 and passes through the limiting protrusion 17 to move to the other end of the arc-shaped limiting groove 16, so that the first connecting rod 11 and the second connecting rod 12 reach the opening and closing limit. At this time, the fixed length connecting rod 8 is connected to the two middle supports through the fixing bolt 9, so that the silencing unit 3 is unfolded to form a complete silencing effect.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
