Description

Technical Field

[0001] The present invention relates to the technical field of sound insulation barriers, and in particular to a mobile sound insulation barrier with a quick-release connection structure. Background Art

[0002] As an important sound insulation facility, the main function of the sound barrier is to insert a physical barrier between the sound source and the receiver to significantly attenuate the propagation of sound waves, thereby reducing the noise impact in the area where the receiver is located. Such facilities are particularly common in outdoor environments, especially at a time when road traffic noise pollution is becoming increasingly serious. Many countries widely use various forms of sound insulation barriers to reduce traffic noise. In addition, inside buildings, for occasions where sound insulation requirements are not high, such as separating workshops and offices, sound insulation barriers can also be used to achieve a certain sound insulation effect.

[0003] For example, the mobile sound insulation barrier for substation sound insulation with publication number CN103485433A realizes mobility by cooperating with a base with universal wheels at the bottom to facilitate quick placement for sound insulation. However, the integral fixed structure still has certain inconveniences: first, the integral sound insulation barrier is bulky and difficult to be quickly disassembled and assembled before use in various scenarios, and it is also inconvenient to transport it quickly. Secondly, when a local area of ​​the sound insulation barrier is damaged, it often needs to be replaced as a whole. It is difficult to quickly replace the local damaged area for repair, which is time-consuming and labor-intensive, and also greatly reduces the utilization rate of the rest of the sound insulation barrier. Summary of the invention

[0004] The object of the present invention is to provide a mobile sound insulation barrier with a quick-detachable connection structure, which realizes modular quick-detachable combination of multiple sound insulation panel units by combining a fixed frame with a quick-detachable connection component, so as to avoid the inconvenience of transportation of traditional integral sound insulation barriers and the targeted replacement of local area damage. Combined with a fixed sealing component, it can not only further increase the stability of the sound insulation panel units after assembly, but also assist in improving the overall sound insulation performance of the assembled sound insulation barrier, so as to solve the technical defects proposed by the background technology.

[0005] The object of the present invention can be achieved by the following technical scheme: A mobile sound insulation barrier with a quick-release connection structure, comprising a mobile base, and a fixed frame fixedly installed on the top of the mobile base, wherein a plurality of sound insulation screen units are detachably installed in the fixed frame, and a quick-release connection component and a fixed sealing component are arranged on the fixed frame;

[0006] The quick-release connection assembly includes movable blocks located on both sides of the corresponding sound insulation screen unit and sliding with the fixed frame, the two sides of the sound insulation screen unit are fixedly connected with a rotating shaft and a guide column, the movable block is provided with a card slot adapted to the corresponding rotating shaft, the fixed frame is provided with an L-shaped guide groove adapted to the guide column, and the fixed sealing assembly includes two groups of L-shaped abutment seats arranged in a mirror image, and a strip sealing block is fixedly connected to one side of the L-shaped abutment seat.

[0007] Preferably, the limiting blocks are symmetrically fixed on both sides of the top and bottom of the slot, the limiting slots are symmetrically provided on both sides of the rotating shaft, and the fixing frame is provided with a clearance slot matching the corresponding slot.

[0008] Preferably, a step hole is provided at the top of the movable block, and a T-bar two is fixedly connected at the bottom to slide with the corresponding step hole, a fixed crossbeam is provided at the top of the fixed frame, and a T-bar one is fixedly connected at the bottom of the fixed crossbeam to slide with the corresponding step hole, and sealing strips are installed on both the top and bottom sides of the sound insulation screen unit.

[0009] Preferably, the lengths of the plurality of T-shaped rods 2 decrease sequentially from bottom to top.

[0010] Preferably, a linkage seat is fixedly connected to the fixed crossbeam, and a plurality of Z-shaped guide grooves are formed through the linkage seat.

[0011] Preferably, a plurality of plug rods slidably connected to the fixed frame are installed on the L-shaped abutment seat through a support plate, a connecting plate is fixedly connected to the fixed frame, and a connecting groove adapted to the connecting plate is provided, and a connecting hole cooperating with the corresponding plug rods is provided on the connecting plate.

[0012] Preferably, a push plate is slidably connected to the L-shaped abutment seat, and an auxiliary plate is welded on the push plate, a guide rod sliding with the corresponding Z-shaped guide groove is fixedly connected between the auxiliary plates, and a plurality of springs are fixedly connected between the auxiliary plate and the L-shaped abutment seat.

[0013] Preferably, an extrusion plate cooperating with the push plate is rotatably connected on the L-shaped abutment seat and located between the push plate and the strip-shaped sealing block, and an L-shaped block is slidably connected to one of the guide rods.

[0014] Preferably, a limit plate extending to the inside of the corresponding Z-shaped guide groove is slidably connected to the linkage seat, and a vertical plate is fixedly connected between the ends of the limit plate, and a tension spring is fixedly connected between the vertical plate and the linkage seat.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) The present invention realizes modular combination of multiple sound insulation panel units by combining a fixed frame with a quick-release connection component, so as to avoid the problem that the traditional integral sound insulation panel is large in size and difficult to carry and transport, and that it is difficult to replace and treat the damaged local area, thereby reducing the overall utilization rate of the sound insulation panel. When the sound insulation panel is disassembled, the limit plate is separated from the guide rod, and the fixed crossbeam is moved to combine with multiple movable blocks to carry multiple sound insulation panel units for separate movement, so that a single sound insulation panel unit can be disassembled. When the sound insulation panel unit is moved, the guide column is guided by the L-shaped guide groove, so that the sound insulation panel unit is autonomously deflected, so that its bottom is moved out of the fixed frame, which can further improve the convenience of disassembly and assembly of the sound insulation panel unit.

[0017] (2) The present invention also uses the fixed crossbeam to carry the linkage seat to move, combined with the Z-shaped guide groove to guide the guide rod, and synchronously links the L-shaped abutment seat to carry the strip sealing block to move, so that the sound insulation panel unit is separated from the strip sealing block before disassembly and abuts against the strip sealing block after assembly, thereby avoiding interference with the deflection movement of the sound insulation panel unit and improving the stability after assembly, effectively avoiding the problem of additional noise caused by unstable installation of the sound insulation panel unit;

[0018] (3) The present invention also uses the guide rod to carry the movement of the auxiliary plate, which can not only achieve the abutment and fixing effect between the sound insulation screen panel unit and the strip sealing block in combination with the spring, but also prompt the push plate to push the inclined extrusion plate to deflect and extrude the strip sealing block, so that the strip sealing block simultaneously squeezes the sound insulation screen panel and the fixed frame to achieve the blocking of the gap between the sound insulation screen panel and the fixed frame, thereby improving the overall sound insulation effect of the assembled sound insulation barrier; in addition, by means of the L-shaped abutment seat combined with the support plate to carry the movement of multiple insertion rods, the fixing effect of the two groups of fixed frames after splicing can be achieved synchronously, further achieving the efficiency of rapid disassembly and assembly of the single sound insulation screen and multiple groups.

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 8 As shown, the following solutions can be used to solve the problems that the integrated sound insulation barrier in the prior art is large in size and difficult to transport and convey, and that it is difficult to replace and treat the damaged local area, thereby reducing the overall utilization rate of the sound insulation barrier;

[0035] In the present embodiment, a mobile sound barrier with a quick-release connection structure includes a mobile base 1, a lifting wheel is provided at the bottom of the mobile base 1, and the wheel is removed from the inside of the mobile base 1 when moving. When used for sound insulation, the wheel is stored inside the mobile base 1 to improve the sound insulation effect, and a fixed frame 11 fixedly installed on the top of the mobile base 1, and a plurality of sound insulation screen units 12 are detachably installed in the fixed frame 11. By combining the fixed frame 11 with the plurality of sound insulation screen units 12, the sound barrier is modularly combined to avoid the large size of the traditional integral sound barrier, which is difficult to carry and transport. The fixed frame 11 is provided with a quick-release connection component 2 and a fixed sealing component 3;

[0036] The quick-release connection assembly 2 includes movable blocks 21 located on both sides of the corresponding sound insulation panel unit 12 and sliding with the fixed frame 11. The two sides of the sound insulation panel unit 12 are fixedly connected with the rotating shaft 13 and the guide column 14. The movable block 21 is provided with a card slot 22 adapted to the corresponding rotating shaft 13. Through the movement of multiple movable blocks 21, the sound insulation panel unit 12 is driven to separate and move in combination with the rotating shaft 13 and the card slot 22, so as to replace a single damaged sound insulation panel unit 12, so as to achieve targeted replacement when a local area is damaged, thereby improving the utilization effect of the rest of the sound insulation barrier as a whole;

[0037] The fixed frame 11 is provided with an L-shaped guide groove 15 adapted to the guide column 14. During the upward separation process of the sound insulation panel unit 12, the guide column 14 is guided by the L-shaped guide groove 15, so that the guide column 14 is moved out of the L-shaped guide groove 15, causing the sound insulation panel unit 12 to deflect upward autonomously, causing its bottom to move out of the fixed frame 11, which can further improve the convenience of disassembly and assembly of the sound insulation panel unit 12. The fixed sealing assembly 3 includes two sets of L-shaped abutting seats 31 arranged in a mirror image, and a strip sealing block 32 is fixedly connected to one side of the L-shaped abutting seat 31.

[0038] The top and bottom sides of the slot 22 are symmetrically fixed with limit blocks, and the distance between the two sets of limit blocks is greater than the diameter of the shaft 13, so as to prevent the shaft 13 from shaking significantly in the slot 22. The two sides of the shaft 13 are symmetrically provided with limit slots, and the dimension between the two sets of limit slots is smaller than the dimension between the two sets of limit blocks, so as to be used for taking the shaft 13 out of the slot 22. The two sets of limit slots are arranged in parallel with the sound insulation side wall of the sound insulation panel unit 12, so as to prevent the slot 22 and the shaft 13 from being easily separated after the sound insulation panel unit 12 is installed.

[0039] The fixing frame 11 is provided with a clearance groove 16 which matches with the corresponding clamping groove 22, and is further used for disassembling and removing the sound insulation panel unit 12. The sound insulation panel unit 12 is moved upward and separated until the clamping groove 22 is connected with the corresponding clearance groove 16, and the sound insulation panel unit 12 to be replaced is rotated upward to a horizontal state, and the rotating shaft 13 is taken out through the two groups of limit blocks, thereby realizing the disassembly and removal of the sound insulation panel unit 12, and then the replacement process is completed by reverse operation.

[0040] The top of the movable block 21 is provided with a step hole 23, and the bottom is fixedly connected with a T-shaped rod 24 that slides with the corresponding step hole 23. By pulling the movable block 21 located at the top, the T-shaped rod 24 at the bottom thereof slides in the corresponding step hole 23, so that the multiple movable blocks 21 are separated in sequence, and then the multiple movable blocks 21 are synchronously moved, so that the multiple sound insulation screen panel units 12 are separated from each other and then turned upward;

[0041] A fixed crossbeam 25 is provided on the top of the fixed frame 11, and a T-shaped rod 26 that slides with the corresponding step hole 23 is fixedly connected to the bottom of the fixed crossbeam 25. The fixed crossbeam 25 moves upward to drive the movable block 21 located above to move through the T-shaped rod 26. Sealing strips are installed on both the top and bottom sides of the sound insulation panel unit 12 to increase the sealing between the multiple sound insulation panel units 12 that collide with each other.

[0042] The fixed crossbeam 25 moves downward, and under the gravity of the sound insulation panel unit 12, the guide column 14 enters the corresponding L-shaped guide groove 15, and then the multiple movable blocks 21 move and contact each other, which simultaneously causes the sound insulation panel units 12 to contact and squeeze the sealing strips, thereby blocking the gaps between the sound insulation panel units 12, thereby increasing the sound insulation effect.

[0043] The lengths of the multiple T-shaped rods 24 decrease from bottom to top. The different lengths of the multiple T-shaped rods 24 are used to reduce the distances that the multiple movable blocks 21 move before synchronous movement, thereby quickly completing the separation of the multiple sound insulation panel units 12 from each other.

[0044] A linkage seat 27 is fixedly connected to the fixed cross beam 25 , and a plurality of Z-shaped guide grooves 28 are formed through the linkage seat 27 .

[0045] A plurality of plug rods 34 slidably connected to the fixed frame 11 are installed on the L-shaped abutment seat 31 through the support plate 33. The provided plug rods 34 are used to increase the movement stability of the L-shaped abutment seat 31. A connecting plate is fixedly connected to the fixed frame 11, and a connecting groove adapted to the connecting plate is provided. The provided connecting plate and the connecting groove are used to realize the connection between two adjacent fixed frames 11, thereby realizing a large-area sound insulation effect. A sealing gasket is provided on one side of the fixed frame 11 to increase the sound insulation sealing performance of the connection between two adjacent groups of fixed frames 11.

[0046] The connecting plate is provided with connecting holes that cooperate with the corresponding plug rods 34. Before the L-shaped abutment seat 31 moves, the two groups of fixed frames 11 are spliced, so that the connecting plate on one group of fixed frames 11 is plugged into the connecting groove on the other group. While the L-shaped abutment seat 31 is combined with the support plate 33 to carry multiple plug rods 34 to move, the plug rods 34 are plugged into the corresponding connecting holes on the connecting plate to complete the quick connection processing between multiple groups of fixed frames 11.

[0047] A push plate 35 is slidably connected to the L-shaped abutment seat 31, and an auxiliary plate 36 is welded to the push plate 35. A guide rod 37 that slides with the corresponding Z-shaped guide groove 28 is fixedly connected between the auxiliary plates 36. A plurality of springs 38 are fixedly connected between the auxiliary plates 36 and the L-shaped abutment seat 31.

[0048] By lowering the linkage seat 27, the guide rod 37 moves in the corresponding Z-shaped guide groove 28, and the Z-shaped guide groove 28 guides the guide rod 37, so that the auxiliary plate 36 is pushed in combination with the spring 38 to drive the L-shaped abutment seat 31 to move close to the sound insulation screen unit 12, thereby realizing the connection between multiple groups of fixed frames 11. The multiple Z-shaped guide grooves 28 and the corresponding guide rods 37 are used to increase the movement effect of the L-shaped abutment seat 31 when the linkage seat 27 moves.

[0049] An extrusion plate 39 cooperating with the push plate 35 is rotatably connected on the L-shaped abutment seat 31 and located between the push plate 35 and the strip sealing block 32. An L-shaped block 310 is slidably connected to one of the guide rods 37. After the slot 22 is connected to the corresponding give-way slot 16, the L-shaped block 310 on the guide rod 37 is moved to the bottom of the linkage seat 27 to limit the downward movement of the fixed beam 25, so as to facilitate the replacement of the sound insulation screen unit 12.

[0050] A limit plate 29 extending to the inside of the corresponding Z-shaped guide groove 28 is slidably connected to the linkage seat 27, and a vertical plate is fixedly connected between the ends of the limit plate 29. A tension spring 210 is fixedly connected between the vertical plate and the linkage seat 27. The vertical plate is pulled to stretch the tension spring 210, so that one end of the limit plate 29 moves out of the corresponding Z-shaped guide groove 28, thereby releasing the position restriction of the limit plate 29 on the guide rod 37 in the Z-shaped guide groove 28;

[0051] This facilitates the upward movement of the linkage seat 27 and the fixed crossbeam 25 to complete the replacement of the corresponding sound insulation panel unit 12. The bottom of the limiting plate 29 located on one side of the Z-shaped guide groove 28 is provided with an inclined surface, so that when the guide rod 37 moves upward relative to the linkage seat 27 in the Z-shaped guide groove 28, it can automatically push the limiting plate 29 to move, thereby achieving a self-locking effect after the sound insulation panel unit 12 is assembled and fixed.

[0052] Example 2: Please refer to Figure 2 , Figure 4 , Figure 8 and Fig. 9 As shown, the following solutions can be used to solve the problem of difficulty in further increasing assembly stability and effectively avoiding the problem of additional noise caused by unstable installation of the sound insulation panel unit;

[0053] In this embodiment, a linkage seat 27 is fixedly connected to the fixed cross beam 25 , and a plurality of Z-shaped guide grooves 28 are formed through the linkage seat 27 .

[0054] A plurality of plug rods 34 slidably connected to the fixed frame 11 are installed on the L-shaped abutment seat 31 through a support plate 33. The support plate 33 is not only used to install the plug rods 34 to increase the movement stability of the L-shaped abutment seat 31, but also used for the installation of the auxiliary plate 36, and by limiting the position of the auxiliary plate 36, the push plate 35 is prevented from being separated from the L-shaped abutment seat 31. A connecting plate is fixedly connected to the fixed frame 11, and a connecting groove adapted to the connecting plate is opened, and a connecting hole matching the corresponding plug rod 34 is opened on the connecting plate.

[0055] A push plate 35 is slidably connected to the L-shaped abutment seat 31, and an auxiliary plate 36 is welded to the push plate 35. A guide rod 37 that slides with the corresponding Z-shaped guide groove 28 is fixedly connected between the auxiliary plates 36. A plurality of springs 38 are fixedly connected between the auxiliary plates 36 and the L-shaped abutment seat 31.

[0056] By lowering the linkage seat 27 and guiding the guide rod 37 with the help of the Z-shaped guide groove 28, the auxiliary plate 36 is pushed in combination with the spring 38 to drive the L-shaped abutting seat 31 equipped with the strip sealing block 32 to move close to the sound insulation screen unit 12, so that the strip sealing block 32 abuts against the sound insulation screen unit 12 to further increase its stability after assembly, and effectively avoid the problem of additional noise caused by unstable installation of the sound insulation screen unit 12.

[0057] An extrusion plate 39 cooperating with the push plate 35 is rotatably connected on the L-shaped abutment seat 31 and located between the push plate 35 and the strip sealing block 32. With the movement of the auxiliary plate 36, the push plate 35 slides on the L-shaped abutment seat 31, and pushes the inclined extrusion plate 39 to deflect and extrude the strip sealing block 32. The sound insulation screen unit 12 and the fixed frame 11 are simultaneously squeezed by the strip sealing block 32 to block the gap between the sound insulation screen unit 12 and the fixed frame 11, thereby improving the overall sound insulation effect of the assembled sound insulation barrier. An L-shaped block 310 is slidably connected to one of the guide rods 37.

[0058] Example 3: Please refer to Figure 1-Figure 9 As shown, the present invention also provides a method for using a mobile sound insulation barrier with a quick-detachable connection structure, comprising the following steps:

[0059] Step 1: Pull the vertical plate to stretch the tension spring 210, so that one end of the limit plate 29 moves out of the corresponding Z-shaped guide groove 28, and pushes the linkage seat 27 to carry the fixed beam 25 to move upward. The fixed beam 25 drives the movable block 21 located above to move through the T-shaped rod 1 26, and combines with multiple T-shaped rods 24 of different lengths to promote the separation of multiple movable blocks 21 from each other. After that, the rotation shaft 13 cooperates with the card slot 22 to complete the upward movement and separation of multiple sound insulation screen panel units 12;

[0060] Step 2: During the upward separation of the sound insulation panel unit 12, the guide column 14 is guided by the L-shaped guide groove 15 so that the guide column 14 moves out of the L-shaped guide groove 15, causing the sound insulation panel unit 12 to deflect upward until the clamping groove 22 is connected with the corresponding clearance groove 16, and the L-shaped block 310 on the guide rod 37 is moved to the bottom of the linkage seat 27 to limit the downward movement of the fixed crossbeam 25, and the sound insulation panel unit 12 to be replaced is rotated upward to a horizontal state, so that the rotating shaft 13 passes through the two sets of limit blocks, and the sound insulation panel unit 12 is disassembled and removed, and then the reverse operation is performed to complete the replacement process;

[0061] Step 3: Move the L-shaped block 310 to make the fixed crossbeam 25 and the linkage seat 27 move downward. Under the gravity of the sound insulation panel unit 12, the guide column 14 enters the corresponding L-shaped guide groove 15. Then, with the mutual movement of the multiple movable blocks 21, the multiple sound insulation panel units 12 are quickly assembled with each other. With the descent of the linkage seat 27, the guide rod 37 moves in the corresponding Z-shaped guide groove 28. The Z-shaped guide groove 28 guides the guide rod 37, and the auxiliary plate 36 is driven in combination with the spring 38 to drive the L-shaped abutment seat 31 equipped with the strip sealing block 32 to move close to the sound insulation panel unit 12, so that the strip sealing block 32 abuts against the sound insulation panel unit 12 to further increase its stability after assembly.

[0062] Step 4: With the movement of the auxiliary plate 36, the push plate 35 slides on the L-shaped abutment seat 31, and pushes the inclined extrusion plate 39 to deflect and extrude the strip sealing block 32, and the strip sealing block 32 simultaneously extrude the sound insulation screen unit 12 and the fixed frame 11, and the gap between the sound insulation screen unit 12 and the fixed frame 11 is blocked. After the linkage seat 27 completes the guidance of the guide rod 37, the guide rod 37 contacts the corresponding limit plate 29, and through the inclined surface below the end of the limit plate 29, the limit plate 29 is pushed to move and stretch the tension spring 210 until the guide rod 37 moves to the upper part of the limit plate 29, and the limit plate 29 is reset to lock the position of the fixed crossbeam 25, and through the mutual contact between the movable blocks 21, the sound insulation screen units 12 are simultaneously caused to contact and squeeze the sealing strip, and the gap between the sound insulation screen units 12 is blocked, thereby increasing the sound insulation effect;

[0063] Step 5: Before the L-shaped abutment seat 31 moves, the two groups of fixed frames 11 are spliced ​​so that the connecting plate on one group of fixed frames 11 is plugged into the connecting groove on the other group. While the L-shaped abutment seat 31 is combined with the support plate 33 to carry multiple plug rods 34 to move, the plug rods 34 are plugged into the corresponding connecting holes on the connecting plate to complete the quick connection processing between the multiple groups of fixed frames 11, and the running wheels on the mobile base 1 are stored inside the mobile base 1, thereby completing the assembly of the sound insulation barrier.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
