Description

Technical Field

[0001] This utility model relates to the field of construction site equipment technology, specifically a spray system used for cooling, dust reduction, and noise reduction at construction sites. Background Technology

[0002] As the number and scale of construction sites continue to increase, the resulting environmental problems are becoming increasingly serious. Among them, dust and noise are common environmental pollution problems at construction sites.

[0003] Construction operations such as waste transportation, drilling, and blasting excavation, which are extremely important on construction sites, generate a lot of dust and noise. These have an adverse effect on the surrounding environment and the health of construction workers, and fail to meet the green construction requirements of the construction industry.

[0004] Patent CN219111181U discloses a dust suppression device for construction sites, which achieves dust suppression by spraying water through nozzles. However, the device lacks environmental quality monitoring capabilities, requiring manual monitoring of the environment to ensure construction site safety, which is labor-intensive.

[0005] Patent CN208072314U discloses a dust suppression and cooling system for construction sites. This dust suppression and cooling system is only equipped with noise sensors and noise alarm devices, but no noise reduction devices are installed. Therefore, the noise pollution is serious and affects the green construction effect. Utility Model Content

[0006] The problem to be solved by this utility model is to address at least one of the problems in the background art by providing a sprinkler system for construction sites.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sprinkler system for construction sites, including an installation frame for installation at construction sites, characterized in that: the installation frame is formed by splicing together at least three installation rods (1), the installation frame forms at least one polygon, and the angle between the plane of the polygon and the ground is in the range of [45°, 90°]; a water supply pipe (61) is installed on the installation frame, and a sprinkler head (7) is installed on at least one side of the water supply pipe (61).

[0008] The spray system also includes a sound-absorbing plate (4), which is limited by each mounting rod (1) and thus installed inside the mounting frame.

[0009] By adopting the above technical solution, the mounting rods are spliced ​​to form an installation frame, which facilitates the confinement of the sound-absorbing panel inside the installation frame (i.e., within the polygon), thereby achieving a noise barrier effect and reducing the noise impact of the construction site on the surrounding area. It also has a certain pollution blocking effect. In addition, by using sprinkler heads, water can be sprayed in the direction of the construction site. For pollutants that are carried by the air to the vicinity of the sprinkler system, the water droplets can be used to make the airborne pollutants fall to the ground, thereby reducing the spread of pollutants from the construction site to the surrounding area.

[0010] Furthermore, the mounting frame is formed by splicing together at least four mounting rods (1); the mounting frame is also provided with at least N-3 connecting rods (3); each end of each connecting rod (3) is connected to the connection position of two adjacent mounting rods (1);

[0011] The at least N-3 connecting rods (3) divide the inner space of the polygon into at least N-2 sub-parts, each sub-part being a triangle, where N is the number of sides of the polygon and N≥4.

[0012] By using connecting rods, the polygonal mounting frame is divided into sub-parts that are all relatively stable triangles, making the overall structure of the mounting frame more stable.

[0013] Furthermore, the sprinkler system also includes a first connector (2) for connecting adjacent mounting rods (1), the first connector (2) including a connector body (23) and mounting sleeves (21) disposed on the connector body (23), the number of mounting sleeves (21) being not less than the number of mounting rods (1) connected to the first connector (2); the mounting rods (1) extend into the corresponding mounting sleeves (21) or are sleeved on the outside of the mounting sleeves (21) to connect with the first connector (2);

[0014] Alternatively, adjacent mounting rods (1) are connected by a hinge.

[0015] By adopting the above technical solution, adjacent mounting rods can be connected to each other through the mounting sleeve of the first connector, or through a hinged connection.

[0016] Furthermore, at least one first connector (2) has at least two mounting sleeves (21), and the first connector (2) is integrally formed into an L-shaped structure; or

[0017] At least one first connector (2) has at least three mounting sleeves (21), and the first connector (2) is integrally formed into a T-shaped structure or a Y-shaped structure; or

[0018] At least one first connector (2) has at least four mounting sleeves (21), and the first connector (2) is integrally formed into a cross-shaped structure.

[0019] By adopting the above technical solution, when K≥3, after forming a polygonal installation frame, more connecting rods can be connected to the outside of the polygon through unused sleeves, thereby forming a noise blocking structure with a larger area, which is suitable for construction sites of different sizes and shapes.

[0020] Furthermore, the spray system also includes a second connector (8);

[0021] The mounting rod (1) is provided with mounting protrusions (22), and the second connector (8) has a first limiting segment (81) and a second limiting segment (82) that respectively limit two adjacent mounting protrusions (22).

[0022] When two adjacent mounting rods (1) are connected, the mounting protrusions (22) of the two adjacent mounting rods (1) are connected by the second connector (8).

[0023] Furthermore, the mounting rod (1) is correspondingly equipped with a water supply pipe (61); at least one water supply pipe (61) is equipped with the spray head (7).

[0024] In the preferred technical solution, each first connector (2) is provided with a corresponding pipe joint, and each port of the pipe joint is connected to the water supply pipe (61) on the corresponding mounting rod (1).

[0025] By adopting the above technical solution, when building a larger noise barrier structure, water can be directed through various water pipes via pipe joints, thereby achieving spraying over a larger area and providing a cooling effect.

[0026] Furthermore, the mounting rod (1) is provided with at least one mounting groove for mounting the sound-absorbing plate (4), and the mounting groove limits the position of the sound-absorbing plate (4); the mounting groove extends along the length of the mounting rod (1). When the mounting rods (1) are spliced ​​together to form a mounting frame, the opening of at least one mounting groove of each mounting rod (1) is set facing the inside of the polygon; the opening of the mounting groove is perpendicular to the length of the mounting rod (1).

[0027] By adopting the above technical solution, the sound-absorbing plate can be conveniently positioned inside the polygon, thereby fixing the sound-absorbing plate.

[0028] Furthermore, the mounting frame forms at least two polygons, wherein two adjacent polygons share a common edge;

[0029] The mounting rod (1) used to form the common edge has a first mounting groove (11) for mounting the sound-absorbing plate (4) and a second mounting groove (12) for mounting the sound-absorbing plate (4); the first mounting groove (11) and the second mounting groove (12) both extend in the length direction of the mounting rod (1); the opening orientation of the first mounting groove (11) and the opening orientation of the second mounting groove (12) are both perpendicular to the length direction of the mounting rod (1);

[0030] When both the first mounting slot (11) and the second mounting slot (12) are equipped with sound-absorbing plates (4), the sound-absorbing plate (4) installed in the first mounting slot (11) and the sound-absorbing plate (4) installed in the second mounting slot (12) are different sound-absorbing plates (4).

[0031] The sound-absorbing plate (4) installed in the first mounting slot (11) is limited to one of the two adjacent polygons;

[0032] The silencing plate (4) installed in the second mounting slot (12) is limited to the other of the two adjacent polygons.

[0033] By adopting the above technical solution, the sound-absorbing panels contained in at least two polygons can cover a larger area and achieve better noise blocking effect.

[0034] Furthermore, the mounting rod (1) for forming the common edge includes a first rod portion (1A) and a second rod portion (1B) respectively; the first rod portion (1A) has a protrusion structure (13), and the second rod portion (1B) has a groove (14).

[0035] The protruding structure (13) of the first rod part (1A) and the groove (14) of the second rod part (1B) cooperate with each other to form the mounting rod (1), and the first rod part (1A) and the second rod part (1B) both extend in the length direction of the mounting rod (1).

[0036] By adopting the above technical solution, the protruding structure and the groove cooperate to fix the first rod and the second rod together to form the mounting rod.

[0037] Furthermore, the first rod portion (1A) includes a mounting base (15) and the protruding structure (13) disposed on the mounting base (15).

[0038] The mounting base (15) and the protruding structure (13) are fixedly connected to each other or are an integral structure.

[0039] Furthermore, the mounting base (15) and the protruding structure (13) are connected by an extension (16);

[0040] The mounting base (15), extension (16), and protrusion structure (13) form a first limiting groove (18A) and a second limiting groove (18B).

[0041] The first limiting groove (18A) and the second limiting groove (18B) are located on both sides of the extension section (16);

[0042] A first protrusion (17A) and a second protrusion (17B) are formed on both sides of the groove (14) of the second rod (1B).

[0043] The first rod portion (1A) and the second rod portion (1B) have a first connection state, a second connection state, and a third connection state;

[0044] When the first rod portion (1A) and the second rod portion (1B) are in the first connection state, the first protrusion (17A) extends into the first limiting groove (18A), the first protrusion (17A) contacts the mounting base (15) and / or contacts the extension section (16), and there are gaps between the second protrusion (17B) and the mounting base (15) and between the second protrusion (17B) and the extension section (16);

[0045] When the first rod portion (1A) and the second rod portion (1B) are in the second connection state, the second protrusion (17B) extends into the second limiting groove (18B), the second protrusion (17B) contacts the mounting base (15) and / or contacts the extension section (16), and there are gaps between the first protrusion (17A) and the mounting base (15) and between the first protrusion (17A) and the extension section (16);

[0046] When the first rod (1A) and the second rod (1B) are in the third connection state, there are gaps between the first protrusion (17A) and the mounting base (15), between the first protrusion (17A) and the extension (16), between the second protrusion (17B) and the mounting base (15), and between the second protrusion (17B) and the extension (16).

[0047] By adopting the above technical solution, when the first rod and the second rod are in the first connection state and the second connection state, respectively, the first rod and the second rod are mutually limited, that is, the first rod rotates relative to the second rod to the first limit position and the second limit position. When in the third connection state, it is the position between the two limit positions. Through the above setting, the first rod can rotate relative to the second rod between the first limit position and the second limit position, thereby adjusting the included angle between the opening orientation of the first groove and the opening orientation of the second groove, thereby adjusting the included angle between the sound-absorbing plate limited by the first groove and the sound-absorbing plate limited by the second groove, which is suitable for different installation occasions.

[0048] Furthermore, the spray system also includes a first connector (2) for connecting adjacent mounting rods (1), the first connector (2) including a connector body (23) and a mounting sleeve (21) disposed on the connector body (23), the mounting rod (1) extending into the corresponding mounting sleeve (21) or sleeved on the outside of the mounting sleeve (21) to connect with the first connector (2);

[0049] In the length direction of the mounting rod (1), the size of the protruding structure (13) is larger than the size of the mounting base (15) and larger than the size of the second rod (1B), so that when the first rod (1A) and the second rod (1B) are connected to each other, the two ends of the protruding structure (13) in the length direction of the mounting rod (1) respectively extend into the mounting sleeve (21) of the corresponding first connector (2), thereby cooperating with the corresponding first connector (2).

[0050] By adopting the above technical solution, the two ends of the protruding structure in the length direction of the mounting rod extend into the two mounting sleeves of the two first connectors respectively, thereby cooperating with the corresponding two first connectors.

[0051] Furthermore, the outer wall of the protruding structure (13) has an arc surface; the groove (14) is an arc-shaped groove that is interference-fitted with the arc surface.

[0052] By adopting the above technical solution, the connection between the protruding structure and the groove is made more stable.

[0053] Furthermore, the plane containing the polygon makes a 90° angle with the ground.

[0054] The first rod portion (1A) is provided with the first mounting groove (11);

[0055] The second rod portion (1B) is also provided with the second mounting groove (12);

[0056] The circumferential dimension of the arc surface of the protrusion structure (13) is larger than the circumferential dimension of the arc groove, such that:

[0057] When the protruding structure (13) is connected to the groove (14), at least a portion of the arc surface of the protruding structure (13) is located outside the second rod (1B), that is, a portion of the arc surface of the protruding structure (13) is connected to the arc groove, while the other portion of the arc surface is not connected to the arc groove, and the mounting base (15) abuts against the second rod (1B) or has a gap with the second rod (1B), so that the protruding structure (13) of the first rod (1A) can rotate within a certain angle range relative to the groove (14) of the second rod (1B). The range of rotatable angles depends on the proportion of the at least portion of the arc surface of the protruding structure that is not connected to the arc groove in the circumferential dimension of the arc surface.

[0058] By adopting the above technical solution, since only the two ends of the protruding structure extend into the mounting sleeve, and only the arc-shaped part is connected with the arc-shaped groove, the first rod and the second rod have a certain range of relative rotation. That is, the angle between the surface of the silencing plate installed in the first mounting groove and the surface of the silencing plate installed in the second mounting groove is adjustable within a certain range (depending on the proportion of at least part of the arc surface of the protruding structure in the circumferential dimension). This allows the sprinkler system to form a noise blocking structure within a certain range, and the angle between the two silencing plates can be set according to the shape of the actual construction site, thus being more suitable for noise reduction in the actual construction site area. It also avoids the area enclosed by the sprinkler system being too large, reducing the impact on the surrounding environment, such as reducing the encroachment on the surrounding area.

[0059] Furthermore, when the first rod (1A) and the second rod (1B) are connected to each other, the angle θ between the first ray and the second ray varies within the range of [135°, 225°].

[0060] The first ray (LA) extends from the first position point (P1) to the position of the first mounting groove (11), and the first ray (LA) is parallel to the axis of the first mounting groove (11);

[0061] The second ray (LB) extends from the first position point (P1) to the location of the second mounting groove (12), and the second ray (LB) is parallel to the axis of the second mounting groove (12);

[0062] The first position point (P1) is the point where the axis of the first mounting groove (11) and the axis of the second mounting groove (12) intersect on the protruding structure (13).

[0063] By adopting the above technical solution, the angle between the surface of the silencing plate installed in the first mounting groove and the surface of the silencing plate installed in the second mounting groove is adjustable within a certain range (depending on the proportion of at least part of the arc surface of the protruding structure in the circumferential dimension), thereby enabling the spray system to form a noise blocking structure within a certain range, and the angle between the two silencing plates can be set according to the shape of the actual construction site, thus being more suitable for noise reduction in the actual construction site area.

[0064] Furthermore, the sprinkler system also has a control module (10); the water supply pipe (61) is connected to the water storage device (64) via a water pump (63); the control terminal of the water pump (63) is electrically connected to the control module (10).

[0065] Furthermore, an environmental monitoring device (30) is installed on the mounting frame, and the output end of the environmental monitoring device (30) is connected to the input end of the control module (10).

[0066] Furthermore, the environmental detection device (30) includes at least one of a temperature sensor (301), a humidity sensor (302), a dust concentration sensor (303), and a noise sensor (304).

[0067] Furthermore, a water supply pipe (61) is correspondingly installed on the mounting rod (1);

[0068] Except for the mounting rod (1) located at the bottom of the mounting frame, the water supply pipes (61) on the other mounting rods (1) are all equipped with the spray heads (7).

[0069] By adopting the above technical solution, compared with the existing technology that only sets the spray head on the top mounting rod, this utility model can achieve spraying over a larger area and achieve better cooling and dust removal effects.

[0070] Furthermore, the water supply pipe (61) is provided with an installation joint (62), and the spray head (7) includes a connecting pipe (71) and a spray head body (72) that are connected to each other; the spray head body (72) is provided with spray holes;

[0071] The connecting pipe (71) is connected to the mounting joint (62), thereby making the inner cavity of the corresponding water supply pipe (61), the inner cavity of the connecting pipe (71), the inner cavity of the spray head body (72), and the spray hole connected in sequence.

[0072] By adopting the above technical solution, water from the water supply pipe passes through the connecting pipe and the main body of the spray head in sequence, and is sprayed out from the spray hole to achieve spraying.

[0073] Further, the spray head body (72) includes a base (75) and a rotating part (721) disposed on the base (75), the spray holes are disposed on the rotating part (721), and the rotation axis of the rotating part (721) is parallel to the axis of the connecting pipe (71); or

[0074] The main body (72) of the spray head includes a base (75) and a rotating part (721) disposed on the base (75). The rotating part (721) has an annular structure and is located on the side of the base (75) away from the connecting pipe (71). An end cap (73) is provided on the opening of the rotating part (721) away from the base (75). The spray hole includes a first spray hole (701) opened on the end cap (73) and a second spray hole (702) opened on the wall of the rotating part (721). The end cap (73) is rotatably connected to the rotating part (721). The rotation axis of the end cap (73) and the rotation axis of the rotating part (721) are both parallel to the axis of the connecting pipe (71).

[0075] During the applicant's research, it was discovered that dust generated at the construction site could reach the sprinkler system and clog some of the first or second sprinkler holes. With the above-described design, both the end cap and the rotating part can rotate independently. When some of the desired first / second sprinkler holes become clogged, the end cap / rotating part can be rotated to move the unclogged first / second sprinkler holes to the desired position, thereby achieving sprinkler operation.

[0076] Furthermore, in one embodiment, a valve is provided on the pipeline of each spray head (7), and the control end of the valve corresponding to each spray head (7) on the water supply pipe (61) of the j-th mounting rod (1) is electrically connected to the j-th signal output end of the control module (10), j=1,2,……,J; J is the number of mounting rods (1) with spray heads (7) in the spray system.

[0077] By adopting the above technical solution, the valves of the spray head pipelines located on the same mounting rod can be opened or closed simultaneously, so that each spray head on the same mounting rod can spray or stop spraying at the same time. Alternatively, spray heads on two or more mounting rods can be opened as needed to achieve the effects of cooling, humidification, and pollution reduction.

[0078] Furthermore, in another embodiment, each spray head (7) is provided with a corresponding valve on the pipeline. The control end of the valve corresponding to each spray head (7) on the water supply pipe (61) on the top mounting rod (1) of the mounting frame is electrically connected to the first signal output terminal (IO_1) of the control module (10). The control end of the valve corresponding to each spray head (7) on the water supply pipe (61) on the other mounting rods (1) of the mounting frame is electrically connected to the second signal output terminal (IO_2) of the control module (10).

[0079] By adopting the above technical solution, when the pollution or humidification requirements are low, only the valves of each spray head on the top mounting rod can be opened, meaning only those spray heads on the top mounting rod will spray. When the pollution or humidification requirements are high, all the valves of all the spray heads on each mounting rod can be opened, meaning all the spray heads will spray, thus achieving a better humidification and pollution reduction effect.

[0080] Compared with existing technologies, the beneficial effects of this automated cooling, dust reduction, and noise reduction system for construction sites are as follows: Construction sites often have unique environments with construction vehicle operating areas; the modular installation frame of this invention can be equipped with cooling, dust reduction, and noise reduction devices of different shapes and variable ranges, making it more adaptable. The application of sound-absorbing panels reduces the transmission of noise and pollution during construction, improving the comfort of construction work. This invention can improve the quality of the working environment at construction sites, effectively suppressing dust and noise from construction equipment, and achieving dust reduction, cooling, and noise reduction effects.

[0119] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0120] Example 1

[0121] like Figure 1 As shown, this embodiment 1 provides a sprinkler system for construction sites, including an installation frame for installation at the construction site. The installation frame is formed by splicing together at least three installation rods 1, and the installation frame forms at least one polygon. In this embodiment, the angle between the plane of the polygon and the ground is within the range of 90°, that is, the sound-absorbing plate 4 is perpendicular to the ground. Those skilled in the art can also set the angle between the plane of the polygon and the ground to other angles within the angle range [45°, 90°] according to actual needs. A water supply pipe 61 is installed on the installation frame, and a sprinkler head 7 is installed on at least one side of the water supply pipe 61. The outlet of the sprinkler head 7 is set towards the construction site. The installation frame can be set close to the noise-generating equipment of the construction site, or at least on one side of the construction site (i.e., the installation frame is set on one side of the construction site to block noise from the construction site and the external environment on this side), or at least around the construction site, for example, close to machinery.

[0122] The sprinkler system may also include a base 5 installed at the construction site. A mounting frame is installed on the base 5.

[0123] The spray system also includes a rigid sound-absorbing plate 4, which is limited by each mounting rod 1 and thus installed inside the mounting frame.

[0124] A polygon is a polygon with at least 3 sides, and can be a triangle, a rectangle, or a polygon with at least 5 sides.

[0125] The mounting frame is formed by splicing together at least four mounting rods 1; the mounting frame is also provided with at least N-3 connecting rods 3; each end of each connecting rod 3 is connected to the connection position of two adjacent mounting rods 1; the at least N-3 connecting rods 3 divide the inner space of the polygon into at least N-2 sub-parts, each sub-part being a triangle, where N is the number of sides of the polygon, and N≥4.

[0126] like Figure 1 As shown, in this embodiment, the polygon is a rectangle (quadrilateral), i.e., N=3. Therefore, only one connecting rod 3 is needed to divide the quadrilateral into two triangular structures. In this embodiment, the plane containing the polygon has an angle of 90° with the ground (that is, the surface of the sound-absorbing plate 4 has an angle of 90° with the ground).

[0127] The sprinkler system also includes a first connector 2 for connecting adjacent mounting rods 1. For example... Figure 3-2 As shown, the first connector 2 includes a connector body 23 and a mounting sleeve 21 disposed on the connector body 23. The mounting rod 1 extends into the corresponding mounting sleeve 21 or is fitted onto the outside of the mounting sleeve 21, thereby connecting with the first connector 2. The number of mounting sleeves 21 is not less than the number of mounting rods 1 connected to the first connector 2. In this embodiment, the number of mounting sleeves 21 is K. The K mounting sleeves 21 are respectively used to fit onto the outside of the corresponding mounting rod, thereby fixing the mounting rod. K is the number of mounting rods 1 interconnected with the first connector 2, K≥2; the mounting rod 1 extends into the corresponding mounting sleeve 21 or is fitted onto the outside of the mounting sleeve 21, thereby connecting with the first connector 2.

[0128] The first connector may have the following structural form:

[0129] Type 1: At least one first connector 2 has at least two mounting sleeves 21, and the first connector 2 is integrally formed into an L-shaped structure, such as... Figure 3-2 As shown;

[0130] The second type: at least one first connector 2 has at least three mounting sleeves 21, and the first connector 2 is integrally formed into a T-shaped structure or a Y-shaped structure;

[0131] The third type: at least one first connector 2 has at least four mounting sleeves 21, and the first connector 2 is integrally formed into a cross-shaped structure.

[0132] The mounting protrusion 22 and the connecting rod 3 can have the following structural form (not shown in the figure): The first connecting member 2 is provided with a mounting protrusion 22, and the mounting protrusion 22 can be set at... Figure 3-2 The connecting body 23 shown is equipped with a connecting rod 3 on the mounting frame, and two through holes are provided near both ends of the connecting rod 3. The mounting protrusions 22 on the two opposite and non-adjacent first connecting parts 2 in the mounting frame respectively cooperate with the two through holes, so that the two mounting rods 1 and one connecting rod 3 form a stable triangular structure.

[0133] like Figure 3-2 , Figure 4 As shown, the water supply pipe 61 is provided with an installation joint 62, and the spray head 7 includes a connecting pipe 71 and a spray head body 72 that are connected to each other; the spray head body 72 is provided with spray holes.

[0134] The connecting pipe 71 is connected to the mounting joint 62, thereby making the inner cavity of the corresponding water supply pipe 61, the inner cavity of the connecting pipe 71, the inner cavity of the spray head body 72, and the spray hole connected in sequence.

[0135] The spray head 7 can have one of the following structural forms:

[0136] The first structural form: The spray head body 72 includes a base 75 and a rotating part 721 disposed on the base 75. The spray holes are disposed on the rotating part 721, for example, on the side of the rotating part 721 and / or on the surface of the rotating part away from the base 75. The rotation axis of the rotating part 721 is parallel to the axis of the connecting pipe 71. This structural form is not shown in the figure.

[0137] The second structural form: such as Figure 4 As shown, the main body 72 of the spray head includes a base 75 and a rotating part 721 disposed on the base 75. The rotating part 721 has an annular structure and is located on the side of the base 75 away from the connecting pipe 71. An end cap 73 is disposed on the opening of the rotating part 721 on the side away from the base 75. The spray holes include a first spray hole 701 opened on the end cap 73 and a second spray hole 702 opened on the wall of the rotating part 721. The end cap 73 is rotatably connected to the rotating part 721. The rotation axis of the end cap 73 and the rotation axis of the rotating part 721 are both parallel to the axis of the connecting pipe 71.

[0138] Each mounting rod 1 is equipped with a water supply pipe 61, and the water supply pipes 61 installed on each mounting rod 1 are interconnected. At least one water supply pipe 61 is equipped with a spray head 7. Each first connector 2 is equipped with a pipe joint (e.g., a pipe branch connector or a pipe manifold connector), and each port of the pipe joint is connected to the corresponding water supply pipe 61 on the mounting rod 1. The pipe joint (not shown in the figure) can be fixed to the corresponding first connector 2, for example, a three-way valve or a multi-way valve can be used.

[0139] The water supply pipe can be either rigid or flexible. When using rigid pipe, at the bend, i.e., where the two mounting rods connect, a pipe fitting can be installed on the first connector. That is, the water supply pipe corresponding to each mounting rod is connected to the corresponding interface of the pipe fitting, thereby enabling water flow between different water supply pipes.

[0140] The mounting rod 1 has at least one mounting groove for mounting the sound-absorbing plate 4, and the mounting groove limits the position of the sound-absorbing plate 4; the mounting groove extends along the length of the mounting rod 1. The sound-absorbing plate 4 is encased in the mounting groove after being covered with rubber material. When the mounting rods 1 are spliced ​​to form a mounting frame, the opening of at least one mounting groove on each mounting rod 1 faces the inside of the polygon, thereby facilitating the insertion of the sound-absorbing plate into the mounting groove during splicing and limiting the sound-absorbing plate to the position of the polygon. The opening of the mounting groove faces perpendicular to the length direction of the mounting rod 1.

[0141] When the mounting frame of this embodiment 1 forms at least two polygons, two adjacent polygons have a common edge.

[0142] The mounting rod 1 used to form the common edge has a mounting slot for mounting one sound-absorbing plate 4 and another mounting slot for mounting another sound-absorbing plate 4; both mounting slots extend along the length of the mounting rod 1, and the openings of the two mounting slots are perpendicular to the length of the mounting rod 1. Figure 1 In the middle, the mounting groove opening of the mounting rod 1 on the left side faces to the right, the mounting groove opening of the mounting rod 1 on the right side faces to the left, the mounting groove opening of the mounting rod 1 on the upper side faces downward, and the mounting groove opening of the mounting rod 1 on the lower side faces upward.

[0143] The sound-absorbing plate 4 is wrapped with an elastic material 41 and then extends into the mounting groove of the mounting rod 1. The mounting groove can be a T-shaped groove, and the part of the sound-absorbing plate 4 that extends into the mounting groove can also be a T-shaped structure, thus providing a better limiting effect for the sound-absorbing plate 4. The elastic material 41 is located between the sound-absorbing plate 4 and the inner wall of the mounting groove, thus playing a buffering role and protecting the sound-absorbing plate.

[0144] When both mounting slots of mounting rod 1 are equipped with sound-absorbing plates 4, the sound-absorbing plates 4 installed in the two mounting slots are different sound-absorbing plates 4.

[0145] The sprinkler system also has a control module 10; an environmental monitoring device 30 is installed on the mounting frame, and the output of the environmental monitoring device 30 is connected to the input of the control module 10.

[0146] The environmental detection device 30 includes at least one of a temperature sensor 301, a humidity sensor 302, a dust concentration sensor 303, and a noise sensor 304.

[0147] The mounting rod 1 is equipped with a water supply pipe 61, which can be mounted on the mounting rod 1, for example, using a pipe retainer 65 (which can be a pipe clamp or pipe clip). Except for the mounting rod 1 located at the bottom of the mounting frame, all other mounting rods 1 have water supply pipes 61 equipped with the spray head 7. Figure 4 As shown, the spray head 7 can be a T-shaped structure, and its surface can be porous. Each opening on the surface of the spray head 7 forms its outlet, and the axial direction of each opening is the direction in which the outlet of the spray head 7 faces. The spray head 7 can adopt a structure from existing technology. The mounting connector 62 can be a connector with an internal thread or a threaded opening on the water supply pipe 61. The water supply pipes 61 on each mounting rod 1 are interconnected and then flow back into the water storage device 64. Figure 1 The middle arrow indicates the direction of water flow.

[0148] The spray head 7 includes a connecting pipe 71; a spray head body 72; an end cap 73; a first spray hole 701; and a second spray hole 702.

[0149] In this embodiment 1, the solenoid valve module 40 may include a first solenoid valve, a second solenoid valve, and a third solenoid valve. The specific structural form of the solenoid valve module 40 may be one of the following first and second structural forms.

[0150] The first structural form is as follows: Figure 2-1 As shown. Each spray head 7 has a corresponding valve installed on its pipe. Figure 1 The control terminals of the valves corresponding to each spray head 7 on the water supply pipe 61 on the top mounting rod 1 (that is, one end of the coil L1 of the first solenoid valve) are all electrically connected to the first signal output terminal IO_1 of the control module 10. Figure 1 The control terminals of the valves corresponding to each spray head 7 on the water supply pipe 61 on the left side of the mounting rod 1 (that is, one end of the coil L2 of the second solenoid valve) are all electrically connected to the second signal output terminal IO_2 of the control module 10. Figure 1The control terminals (i.e., one end of the coil L3 of the third solenoid valve) of the valves corresponding to each spray head 7 on the water supply pipe 61 of the mounting rod 1 on the right side are all electrically connected to the third signal output terminal IO_3 of the control module 10. The other ends of the coil L1 of the first solenoid valve, the other ends of the coil L2 of the second solenoid valve, and the other ends of the coil L3 of the third solenoid valve are all electrically connected to the output terminal VCC of the power supply module 20. The power supply voltage of VCC can be 3.3V~5V. In this embodiment, the solenoid valve can be a normally closed solenoid valve. When the signal output terminal of the control module 10 outputs a low-level signal (e.g., 0 level) to energize the corresponding coil, the valves in each spray head corresponding to the solenoid valve open, allowing spraying through the corresponding spray holes. When the signal output terminal of the control module 10 outputs a high-level signal to de-energize the corresponding coil, the valves in each spray head corresponding to the solenoid valve close, preventing water supply to the corresponding spray holes and thus preventing spraying. For example, when the coil L1 of the first solenoid valve is energized, the valves corresponding to each spray head 7 on the water supply pipe 61 on the top mounting rod 1 open, allowing water to be supplied to the spray holes corresponding to each spray head 7 on the water supply pipe 61 on the top mounting rod 1, thus enabling spraying; when the coil L1 of the first solenoid valve is de-energized, the valves corresponding to each spray head 7 on the water supply pipe 61 on the top mounting rod 1 close, preventing water from being supplied to the spray holes corresponding to each spray head 7 on the water supply pipe 61 on the top mounting rod 1, thus preventing spraying. The energization / de-energization of the solenoid valve coil causing the corresponding valves to open / close is a matter of prior art, and will be understood by those skilled in the art.

[0151] The second structural form is as follows: Figure 2-2 As shown. Each spray head 7 has a corresponding valve installed on its pipeline. Figure 1 The control terminals of the valves corresponding to each spray head 7 on the water supply pipe 61 on the mounting rod 1 located at the top (that is, one end of the coil L1 of the first solenoid valve) are all electrically connected to the first signal output terminal IO_1 of the control module 10. Figure 1 The control ends of the valves corresponding to the water supply pipes 61 on the other mounting rods 1 in the mounting frame (i.e., one end of the coil L2 of the second solenoid valve and one end of the coil L3 of the third solenoid valve) are all electrically connected to the second signal output terminal IO_2 of the control module 10.

[0152] The purpose of this utility model is to provide a dust reduction, cooling and noise reduction device for construction sites, which can effectively improve the quality of the working environment at construction sites and at least solve at least one of the problems of existing spray devices, such as lack of noise reduction function, limited dust reduction range and low efficiency of manual monitoring.

[0153] The following is a further detailed description of Embodiment 1 of this utility model.

[0154] A sprinkler system for construction sites is disclosed, used for cooling, dust suppression, and noise reduction. The sprinkler system includes a sprinkler assembly (including individual sprinkler heads), a noise reduction device (i.e., a layer of sound-absorbing material composed of sound-absorbing panels 4), a support structure, an environmental monitoring device, a control module, and a power supply module. The cooling and dust suppression devices are arranged horizontally at the upper and lower ends of the mounting frame, the noise reduction devices are installed inside the mounting frame, and the output of the environmental monitoring device is connected to the control module.

[0155] The support device includes a base 5 (which can be a stable bracket), a first connector 2, and a mounting rod 1. The mounting rod 1 can be assembled into a rectangular mounting frame via the first connector 2. At least one of the inner or outer sides of the mounting rod 1 has a mounting groove to limit the position of the sound-absorbing plate. The mounting rod 1 at the bottom can connect to the base 5, allowing the mounting frame to stand upright on the ground. The mounting rod 1 may have a threaded opening for installing a water pipe limiting component. The water pipe limiting component is used to fix the water supply pipe. The first connector 2 uses a mounting sleeve to assemble the mounting rod 1, and can be L-shaped, T-shaped, or cross-shaped. The specifications and dimensions of the base 5 and the mounting rod 1 need to be customized according to the actual conditions of the construction site. This embodiment adopts a frame assembly type, which makes the space occupied by the water storage tank, cooling and dust removal devices, etc., small, easy to install, practical and efficient.

[0156] The noise reduction device includes a sound-absorbing plate 4 (which can be made of sound-absorbing cotton) and an elastic material 41 (such as rubber). The size of the sound-absorbing plate 4 is determined according to the dimensions of the assembled rectangular frame. The rubber material 5 is wrapped around the sound-absorbing plate 4 and embedded in the inner side of the rectangular frame (i.e., in the mounting groove of each mounting rod), forming the noise reduction device. The elastic material 41 can form a ring structure that conforms to the overall shape of the sound-absorbing plate 4. The sound-absorbing plate 4 can be an existing sound-absorbing plate or a sheet material processed from fibers. The sound-absorbing plate 4 can also block the scattering of dust at low altitudes. The sound-absorbing plate 4 is placed in the inner groove (i.e., mounting groove) of the mounting rod 1. To prevent it from shaking, the edges of the sound-absorbing plate can be wrapped with rubber material, and the sound-absorbing plate wrapped with rubber material is inserted into the mounting groove inside the mounting rod 1.

[0157] The cooling and dust suppression device includes a water supply pipe 61, a water pipe limiting component 65 (which can be a pipe clamp or pipe clip), a pipe joint, a spray head 7 (which can be an atomizing spray head), a solenoid valve 631 for controlling the water pump (not shown in the figure), a water pump 63, and a water storage tank 64. The two electrical connection terminals of the solenoid valve for controlling the water pump are electrically connected to the control terminal of the water pump 63 and the output terminal of the power supply module, respectively. The control terminal of the solenoid valve 631 is electrically connected to the control module. After the control terminal of the solenoid valve is energized, the water pump 63 is energized and operates, delivering water through the water supply pipe 61. The water flows in different directions through the pipe joint. Under the action of water pressure, the spray head 7 atomizes the water delivered by the water supply pipe and sprays it onto the working surface. Depending on the dust concentration and temperature / humidity, some or all of the spray heads 7 can be opened. The outlet orientation of the spray head 7 can be set as needed. The structure of the spray head 7 and the angle adjustment structure of the spray head 7 are existing technologies. The water supply pipe 61 can be made of PVC material, and the pipe joints can be splice-free, enabling quick splicing and rerouting, resulting in greater efficiency and applicability. Under water pressure, the sprinkler heads 7 can be arranged in different directions according to the actual conditions of the construction site, such as horizontal or vertical. Depending on the dust concentration and temperature and humidity, different numbers and intensities of sprinkler heads 7 can be activated. The outlet direction of the sprinkler heads can be adjusted to any angle for efficient operation. In this embodiment, the sprinkler heads are mounted on mounting rods, which can be arranged horizontally or vertically. Compared to the prior art where sprinkler heads are only installed at the top, this embodiment increases the spray range and intensity, resulting in better performance.

[0158] like Figure 2 As shown, the environmental monitoring device includes a temperature sensor, a humidity sensor, a dust concentration sensor, and a noise sensor. The power supply module provides power to the sensors to ensure their normal operation, enabling real-time monitoring and wireless transmission of the acquired signal data to the control module. Each sensor can be set with a corresponding environmental quality detection range. When a certain environmental monitoring value exceeds the threshold, the corresponding sensor issues an early warning and sends the signal data to the control module for appropriate processing. The environmental monitoring device 4 contains multiple sensors, including temperature and humidity sensors and a dust concentration sensor. The temperature and humidity sensor 401 can be an NB-IoT type. The dust concentration sensor 402 uses a CCGZ-1000 direct-reading dust meter and can acquire particulate matter concentrations such as TSP and PM2.5.

[0159] The environmental monitoring device uses various sensors to monitor environmental data (such as temperature, humidity, and noise) in real time and transmits the detected signals to the control module. The control module controls the sprinkler system based on the received signals, activating some or all of the sprinkler heads to achieve cooling, dust reduction, and noise reduction at the construction site. The signal transmission between the environmental monitoring device and the control module, and between the control module and the sprinkler system, as well as the control of the sprinkler system by the control module based on the received signals, are all existing technologies.

[0160] When the humidity does not reach the humidity threshold, or the temperature exceeds the temperature threshold, or the dust concentration exceeds the dust concentration threshold, the water pump can be turned on, and part or all of the spray system can be opened via the solenoid valve. When the humidity reaches the humidity threshold, or the temperature is not higher than the temperature threshold, or the dust concentration is not higher than the dust concentration threshold, the water pump 63 can be turned off. This improves efficiency, saves resources, and reduces errors. The control module's control of the water pump and solenoid valve when the humidity / temperature / dust concentration reaches / does not reach the threshold is based on existing technology. The control module can use a microcontroller, DSP, etc. The signal output terminal of the environmental detection device 4 is connected to the control module 5. The power supply module 6 is connected to the cooling and dust suppression water supply device 3, the environmental detection device 4, and the control module 5 respectively, and provides power.

[0161] The power supply module includes a voltage conversion device and a power switch. One end of the power switch is connected to a power source (e.g., a 220V power supply), and the other end is connected to the input of the voltage conversion device. The output of the voltage conversion device is connected to the cooling and dust suppression device (i.e., each spray head), the water pump, the solenoid valve, the environmental monitoring device, and the control module, thereby supplying power. The voltage conversion device can be a step-down type. The power switch can be a point-contact switch. The output of the step-down type voltage conversion device can be 12V-24V. Neither the power switch nor the voltage conversion device is shown in the figure, which will be understood by those skilled in the art.

[0162] In this embodiment 1, the control module 10, power supply module 20, and solenoid valve module 40 can be set on the outside of the mounting frame. For example, a box can be set on one side of the mounting frame to house each module, thereby achieving a waterproof effect.

[0163] The sprinkler system of this embodiment can be placed near noise-generating devices on the construction site, such as drilling rigs, electric motor accessories, or, for example, near an Atlas air compressor drilling rig.

[0164] Example 2

[0165] The difference between Embodiment 2 and Embodiment 1 is that the mounting rod 1 used to form the common side of the two polygons includes a first rod portion 1A and a second rod portion 1B respectively; the first rod portion 1A has a protruding structure 13, and the second rod portion 1B has a groove 14, such as... Figure 5-1 , Figure 5-2 , Figure 5-3 , Figure 5-4 As shown.

[0166] like Figure 5-5As shown, the sound-absorbing plate 4 is wrapped with an elastic material 41 and then extends into the first mounting groove 11 of the first rod portion 1A. The first mounting groove 11 can be a T-shaped groove, and the part of the sound-absorbing plate 4 that extends into the first mounting groove can also be a T-shaped structure, thus providing a better limiting effect for the sound-absorbing plate 4. The elastic material 41 is located between the sound-absorbing plate 4 and the inner wall of the first mounting groove, thereby playing a buffering role and protecting the sound-absorbing plate.

[0167] The protruding structure 13 of the first rod portion 1A and the groove 14 of the second rod portion 1B cooperate with each other to form the mounting rod 1. Both the first rod portion 1A and the second rod portion 1B extend in the length direction of the mounting rod 1.

[0168] The first rod portion 1A includes a mounting base 15 and the protruding structure 13 disposed on the mounting base 15. An extension section 16 may also be provided between the protruding structure 13 and the mounting base 15, such as... Figure 5-5 As shown, the protruding structure 13 and the extension section 16 are integrally formed on the protrusion of the mounting base 15.

[0169] When the first rod 1A and the second rod 1B are connected to each other, the mounting base 15 is located on the side of the protruding structure 13 away from the second rod 1B.

[0170] The mounting base 15 and the protruding structure 13 are fixedly connected to each other or are an integral structure.

[0171] like Figure 5-1 , Figure 5-3 As shown, the mounting base 15 and the protruding structure 13 are connected by an extension section 16;

[0172] The mounting base 15, extension 16, and protrusion structure 13 form a first limiting groove 18A and a second limiting groove 18B.

[0173] The first limiting groove 18A and the second limiting groove 18B are located on both sides of the extension section 16, and the opening orientations of the first limiting groove 18A and the second limiting groove 18B are opposite.

[0174] A first protrusion 17A and a second protrusion 17B are formed on both sides of the groove 14 of the second rod portion 1B, respectively;

[0175] When the protrusion structure 13 of the first rod portion 1A and the groove 14 of the second rod portion 1B cooperate with each other, the first limiting groove 18A and the second limiting groove 18B are respectively used to limit the first protrusion 17A and the second protrusion 17B.

[0176] The first rod portion 1A and the second rod portion 1B have a first connection state, a second connection state, and a third connection state.

[0177] When the first rod portion 1A and the second rod portion 1B are in the first connected state, the first protrusion 17A extends into the first limiting groove 18A, and the first protrusion 17A contacts the mounting base 15 and / or the extension 16. There are gaps between the second protrusion 17B and the mounting base 15, and between the second protrusion 17B and the extension 16. Figure 6-1 As shown, the first rod 1A and the second rod 1B are in the third connection state.

[0178] When the first rod portion 1A and the second rod portion 1B are in the second connected state, the second protrusion 17B extends into the second limiting groove 18B, and the second protrusion 17B contacts the mounting base 15 and / or the extension 16. There are gaps between the first protrusion 17A and the mounting base 15, and between the first protrusion 17A and the extension 16. Figure 6-3 As shown, the first rod 1A and the second rod 1B are in the second connection state.

[0179] When the first rod portion 1A and the second rod portion 1B are in the third connection state, there are gaps between the first protrusion 17A and the mounting base 15, between the first protrusion 17A and the extension 16, between the second protrusion 17B and the mounting base 15, and between the second protrusion 17B and the extension 16. For example... Figure 6-2 As shown, the first rod 1A and the second rod 1B are in the third connection state.

[0180] In the length direction of the mounting rod 1, the size of the protruding structure 13 is larger than the size of the mounting base 15 and larger than the size of the second rod 1B, so that when the first rod 1A and the second rod 1B are connected to each other, the two ends of the protruding structure 13 in the length direction of the mounting rod 1 respectively extend into the mounting sleeve 21 of the corresponding first connector 2, thereby cooperating with the corresponding first connector 2.

[0181] The outer wall of the protruding structure 13 has an arc surface (preferably a circular arc surface); the groove 14 is an arc-shaped groove that is interference-fitted with the arc surface.

[0182] The first rod portion 1A has a first mounting groove 11. The second rod portion 1B also has a second mounting groove 12. The included angle θ1 between the opening orientation of the first mounting groove 11 and the opening orientation of the second mounting groove 12 is in the range of [45°, 180°].

[0183] The circumferential dimension of the arc surface of the protrusion structure 13 is larger than the circumferential dimension of the arc groove, such that:

[0184] When the protrusion structure 13 is connected to the groove 14, at least a portion of the arc surface of the protrusion structure 13 is located outside the second rod portion 1B, and the mounting base 15 abuts against the second rod portion 1B or has a gap with the second rod portion 1B.

[0185] When the first rod 1A and the second rod 1B are connected to each other, the angle θ between the first ray and the second ray varies within the range of [150°, 210°].

[0186] The first ray LA extends from the first position point P1 to the position of the first mounting groove 11, and the first ray LA is parallel to the axis of the first mounting groove 11;

[0187] The second ray LB extends from the first position point P1 to the position of the second mounting groove 12, and the second ray LB is parallel to the axis of the second mounting groove 12.

[0188] In this embodiment, the first ray is the direction in which the opening of the first mounting groove 11 faces, and the second ray is the direction in which the opening of the second mounting groove 12 faces.

[0189] The first position point (P1) is the point where the axis of the first mounting groove 11 and the axis of the second mounting groove 12 on the protruding structure 13 intersect.

[0190] In this embodiment, the opening orientation of the first mounting groove 11 and the orientation of the protrusion 13 can be opposite. The opening orientation of the second mounting groove 12 and the opening orientation of the groove 14 can be opposite.

[0191] When the first rod 1A and the second rod 1B are connected to each other, the angle between the first ray and the second ray is [90°, 210°] when viewed along the length of the mounting rod 1.

[0192] in:

[0193] The first ray LA extends from the first position point P1 to the position of the first mounting groove 11, and the first ray LA is parallel to the axis of the first mounting groove 11;

[0194] The second ray LB extends from the first position point P1 to the position of the second mounting groove 12, and the second ray LB is parallel to the axis of the second mounting groove 12;

[0195] The first position point (P1) is the point where the axis of the first mounting groove 11 and the axis of the second mounting groove 12 on the protruding structure 13 intersect.

[0196] Figure 6-1 , Figure 6-2 , Figure 6-3This diagram illustrates that, in Embodiment 2 of this invention, the angles θ between the first and second rays are 150°, 180°, and 210°, respectively, when the first and second rods are connected in three different connection states. Depending on the specific shape of the area occupied by the noisy machinery on the actual construction site, different connection states of the first and second rods can be configured to effectively block noise.

[0197] Because of the interference fit between the groove 14 and the arc surface, it can also be rotated to other connection positions, so that the angle between the first ray and the second ray is other angles within the range of [150°, 210°].

[0198] When the mounting frame of this embodiment 2 forms a polygon, the mounting rod 1 forming the sides of the polygon can be adopted. Figures 5-1 to 5-4 The structure can be composed of a first rod 1A and a second rod 1B joined together; or, instead of using two rods joined together, each mounting rod 1 can be a single, integral mounting rod 1, with at least one mounting slot. That is, when the mounting rods 1 are joined to form a polygonal structure, the openings of the mounting slots of each mounting rod 1 face inwards, allowing the sound-absorbing plate 4 to be inserted into each mounting slot, thus confining it to the inner side of each mounting rod 1 (i.e., the location of the polygon).

[0199] When the mounting frame of this embodiment 2 forms at least two polygons, in addition to the mounting rod 1 used to form the common side, other mounting rods 1 may also be used. Figures 5-1 to 5-4 The structure consists of a first rod 1A and a second rod 1B joined together. Alternatively, other mounting rods 1 may not use two rods joined together, but rather a single, integrated mounting rod 1.

[0200] like Figure 7-1 , Figure 7-2 , Figure 7-3 The diagram shows the structure when the mounting frame forms two polygons (rectangles). Figure 7-2 As shown in the top view, the surfaces of both rectangles are perpendicular to the bottom surface, and the included angle between the two rectangular surfaces is an obtuse angle, thus allowing them to adapt to different occlusion shapes. For example... Figure 7-2 , Figure 7-3 As shown, for Figure 7-2 The mounting rod in section M (i.e., the mounting rod forming the common side of the two rectangles) has its first and second sections rotatable as follows: Figure 7-2 The connection positions are shown to accommodate the installation of two sound-absorbing panels 4. Figure 7-3 As shown, the connecting body 23 of the corresponding first connector 2 can have an opening (not shown in the figure), and one of the mounting sleeves 21 can be fitted inside the opening and have an interference fit with the connecting body 23. Figure 7-3The dotted line represents the portion of the mounting sleeve 21 that extends into the opening, i.e., the portion obscured by the connecting body 23 in this view. This allows the axial direction of the mounting sleeve 21 to be adjusted within a certain angle range relative to the axial direction of the connecting body 23, thereby accommodating the corresponding mounting rod (i.e., Figure 7-2 The installation of the mounting rod on the left side. Or, for Figure 7-1 The rectangle on the left can also be installed without the top and bottom mounting rods. That is, the sound-absorbing plate 4 in the rectangle on the left can be installed by two mounting rods on the left and right sides that extend in the direction perpendicular to the ground.

[0201] In this embodiment 2, the mounting rod 1 is divided into a left rod and a right rod (i.e., the first rod section and the second rod section), which are spliced ​​together by a fan-shaped groove, allowing for large-angle rotation to change the included angle between the axes of the first rod section and the second rod section. The water pipe 61 can be mounted on the mounting base 15 or on the second rod section 1B.

[0202] The mounting protrusion 22 and connecting rod 3 can have the following structural forms (e.g.) Figure 5-3 , Figure 5-4 As shown): A mounting protrusion 22 is provided on the second rod 1B, and a groove (not shown in the figure) is opened on the side wall of the mounting sleeve 21 to adapt to the mounting protrusion 22, thereby limiting the mounting protrusion 22. A connecting rod 3 is provided on the mounting frame, and two through holes provided on the connecting rod 3 near both ends respectively cooperate with the two mounting protrusions 22, so that the two mounting rods 1 and one connecting rod 3 form a stable triangular structure.

[0203] When both the first mounting slot 11 and the second mounting slot 12 are equipped with sound-absorbing plates 4, the sound-absorbing plates 4 installed in the first mounting slot 11 and the sound-absorbing plates 4 installed in the second mounting slot 12 are different sound-absorbing plates 4.

[0204] The sound-absorbing plate 4 installed in the first mounting slot 11 is limited to one of the two adjacent polygons. The sound-absorbing plate 4 installed in the second mounting slot 12 is limited to the other of the two adjacent polygons.

[0205] Example 3

[0206] The difference between Embodiment 3 and Embodiment 1 is that the first connecting member may not be provided, and adjacent mounting rods 1 are connected by a hinge. For example:

[0207] Method 1: Each of the two adjacent mounting rods 1 is provided with a mounting protrusion 22. The two mounting protrusions 22 are connected and limited by a second connector 8, thereby achieving a hinged connection between the two mounting rods 1. For example... Figure 8-1 , Figure 8-2 , Figure 8-3As shown, the second connector 8 has a first limiting segment 81 and a second limiting segment 82 that respectively limit two adjacent mounting protrusions 22. The first limiting segment 81 and the second limiting segment 82 are connected to each other through a connecting segment 83. The second connector 8 can be an S-shaped structure, that is, the two openings of the S-shaped structure facing away from each other (formed by the curved first limiting segment 81 and the curved second limiting segment 82 respectively) limit the mounting protrusions 22 of two adjacent mounting rods 1 respectively. One of the mounting protrusions 22 is connected to the connecting rod 3. Optionally, the first limiting segment 81 and the second limiting segment 82 can also both be formed into annular shapes, limiting the mounting protrusions 22 of two adjacent mounting rods 1 respectively. That is, the two annular shapes are connected by the connecting segment 83, and the second connector 8 as a whole forms a figure-eight-like structure.

[0208] The second method (not shown in the figure): One mounting rod 1 is stacked on top of another mounting rod, and the two mounting rods 1 form an L-shaped structure. The structure of the first rod portion 1A and the second rod portion 1B of the mounting rod 1 can be referenced. Figures 5-1 to 5-4 The structure is as follows: Two through holes can be opened near the two ends of the connecting rod 3. The two through holes respectively cooperate with the two mounting protrusions 22, so that the two mounting rods 1 and one connecting rod 3 form a stable triangular structure.

[0209] Example 4

[0210] like Figure 9-1 , Figure 9-2 , Figure 9-3 , Figure 9-4 As shown, the difference between this embodiment 4 and embodiment 2 is that, viewed from the length direction of the second rod 1B, the plane containing the surface of the first protrusion 17A facing away from the groove 14 and the plane containing the surface of the second protrusion 17B facing away from the groove 14 are 90°, which makes the range of the angle θ between the first ray and the second ray [135°, 225°], that is, compared with embodiment 2, the range of rotation angle is increased.

[0211] like Figure 9-3 As shown, the first rod 1A and the second rod 1B are in the third connection state. Figure 9-4 As shown, the first rod 1A and the second rod 1B are in the second connection state.

However, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Without departing from the principle of this utility model, several improvements and refinements can also be made. These improvements and refinements should also be considered within the protection scope of this utility model.
