[0049] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0050] The following is combined with Figure 1-4 The barb wire assembly 100 and the electrostatic precipitator according to the embodiment of the present invention are described in detail.

[0051] like Figure 1-Figure 4 As shown, the barb wire assembly 100 of the embodiment of the present invention includes a barb wire 1 and a first connecting component 2, one end of the barb wire 1 is fixedly connected to a frame 5, and the other end of the barb wire 1 is connected to the frame 5 through the first connecting component 2; the end of the barb wire 1 close to the first connecting component 2 has a first guide portion 14 and a clamping portion 15 arranged in sequence along the length direction of the barb wire 1.

[0052] The first connecting component 2 includes a first seat body 21, a spring leaf 22 and a first sleeve 23. The first seat body 21 is fixedly connected to the frame 5, and the first seat body 21 has a first groove; the spring leaf 22 is arranged on the inner wall surface of the first groove, the clamping portion 15 is arranged in the first groove and the spring leaf 22 abuts against the clamping portion 15; the first sleeve 23 is sleeved on the first guide portion 14, the first sleeve 23 is fixedly connected to the first seat body 21, the inner wall surface of the first sleeve 23 abuts against the first guide portion 14, and the first guide portion 14 is movable in the first sleeve 23 along the length direction of the thorn line 1.

[0053] Both ends of the barb wire 1 are connected to the frame 5, and the clamping portion 15 of the barb wire 1 is clamped in the first groove by the spring 22. During the periodic rapping process, the clamping portion 15 of the barb wire 1 will squeeze the spring 22, and the spring 22 will undergo a certain elastic deformation, so that the clamping portion 15 of the barb wire 1 can move relative to the first connecting component 2 in the length direction of the barb wire 1. The first guide portion 14 is sleeved with the first sleeve 23, which can ensure that the length direction of the barb wire 1 remains unchanged, and can perform adaptive small displacement movement during the rapping process, thereby reducing stress concentration at the connection between the barb wire 1 and the frame 5, and preventing some parts of the barb wire 1 from breaking or even falling off during long-term use.

[0054] In some embodiments, the barb wire 1 includes a wire body 11 and a first plate 12, wherein one end of the wire body 11 close to the first connecting component 2 is a first guide portion 14, and the first guide portion 14 has a hollow inner cavity; a partial section of the first plate 12 is located in the inner cavity of the first guide portion 14, and the other sections of the first plate 12 are clamping portions 15; the end of the first guide portion 14 is contracted to clamp the first plate 12.

[0055] That is to say, the first guide portion 14 and the clamping portion 15 are respectively arranged on two different components, the wire body 11 and the first plate 12. A partial section of the first plate 12 is located in the inner cavity of the first guide portion 14, which can play a role in reinforcing the structure of the first guide portion 14. At the same time, the first plate 12 is clamped by contracting the port of the first guide portion 14, and other connecting parts 35 are not required to connect the first plate 12 and the wire body 11, so as to avoid the connection part 35 from falling off due to corrosion, thereby improving the stability of the structure.

[0056] In addition, the embodiment of the present invention can set the materials of the first plate 12 and the wire body 11 separately. The wire body 11 is made of a conductive and corrosion-resistant material, for example, supported by 304 stainless steel. The first plate 12 can be made of the same material as the wire body 11, or a corrosion-resistant material that does not have conductive properties, such as plastic, composite materials, etc.

[0057] The separate arrangement of the first plate 12 and the wire body 11 can more conveniently ensure the structural stability of different components, facilitate the selection of more suitable materials for manufacturing according to the functions of different components, and improve the practicality of the product.

[0058] like Figure 4 As shown, in some embodiments, the first plate 12 has a first protrusion 121, the reed 22 has a second protrusion 221 facing the first plate 12, the first protrusion 121 and the second protrusion 221 abut against each other, and the first protrusion 121 and the second protrusion 221 are staggered.

[0059] When the first plate 12 and the first connecting member 2 are assembled, the first protrusion 121 and the second protrusion 221 abut against each other. During the abutting process, the spring leaf 22 is deformed to a certain extent, thereby providing a clamping force to the first plate 12 to ensure that the barb wire 1 is in a stable state. When vibration occurs, the barb wire 1 will move a small distance in its length direction. At this time, the spring leaf 22 will deform synchronously, and the force between the first protrusion 121 and the second protrusion 221 will change accordingly. The force on the clamping portion 15 of the barb wire 1 is adjusted in real time to ensure the stability of the structure of the barb wire 1.

[0060] Furthermore, there are two springs 22, which are respectively arranged on two opposite inner wall surfaces of the first groove. The two springs 22 are symmetrically arranged on two opposite side surfaces of the first plate 12, so that the two side surfaces of the first plate 12 are subjected to stable forces and have a better clamping effect.

[0061] Furthermore, one end of the spring leaf 22 is fixed to the first seat body 21, and the other end of the spring leaf 22 is bent in a wavy line to form a supporting section 222, which supports between the first plate 12 and the inner wall surface of the first groove. The middle part of the spring leaf 22 has an arc section protruding toward the first plate 12 and forms a second protrusion 221.

[0062] When the spring leaf 22 is squeezed, one end of the spring leaf 22 is fixed to the first seat body 21 and remains stationary relative to the first seat body 21, and the supporting segment 222 at the other end of the spring leaf 22 will deform and move to a certain extent, thereby causing the arc segment in the middle of the spring leaf 22 to deform. Both the supporting segment 222 and the arc segment will deform with the vibration, and can avoid the problem of stress concentration at the connection part between the spring leaf 22 and the first seat body 21 due to the deformation of the spring leaf 22, thereby improving the structural stability and service life of the spring leaf 22.

[0063] Furthermore, there are multiple first protrusions 121, for example, the number of first protrusions 121 is two, three or four, and the second protrusion 221 can abut against one of the first protrusions 121, or the second protrusion 221 can abut against two adjacent first protrusions 121 at the same time, so that the clamping force acting on the first plate 12 is more stable.

[0064] In some embodiments, a first connecting rod 24 is provided on the first seat body 21, and the first connecting rod 24 is fixed to the first sleeve 23 by a connecting member 35. A second connecting rod 25 is provided between the first sleeve 23 and the frame 5, and one end of the second connecting rod 25 is fixed to the first sleeve 23. The other end of the second connecting rod 25 is provided with a lap joint 26, and the lap joint 26 is fixed to the frame 5.

[0065] That is to say, the first sleeve 23 and the first seat body 21 are a detachable connection structure, which facilitates the installation and assembly of the components, avoids interference between the first sleeve 23 and the first seat body 21 during the assembly process, and ensures smooth assembly.

[0066] The first sleeve 23 is connected to the frame 5 via the second connecting rod 25. The lap joint 26 may be a connecting plate, a U-shaped card plate or a rectangular sleeve arranged on the second connecting rod 25. After the lap joint 26 is assembled with the frame 5, effective contact between the lap joint 26 and the frame 5 is ensured. The lap joint 26 and the frame 5 may also be fixed by setting a connecting member 35 such as bolts.

[0067] In some embodiments, the barb wire assembly 100 further includes a second connecting component 3, and the end of the barb wire 1 away from the first connecting component 2 is fixed to the frame 5 via the second connecting component 3; the end of the barb wire 1 close to the second connecting component 3 has a second guide portion 16 and a fixing portion 17.

[0068] The second connecting component 3 includes a second seat body 31, a third seat body 32 and a second sleeve 33. The second seat body 31 is fixedly connected to the frame 5. The fixing portion 17 is fixedly connected to the second seat body 31 via a connecting member 35. The third seat body 32 is fixedly connected to the frame 5. The second sleeve 33 is sleeved on the second guide portion 16. A third connecting rod 34 is provided between the second sleeve 33 and the third seat body 32.

[0069] That is to say, the end of the barb wire assembly 100 away from the first connecting part 2 can be stepped and fixedly connected to the frame 5 through the second seat body 31, and can be guided by the second sleeve 33, so as to ensure that the barb wire 1 is only subjected to force in its length direction and not to lateral force, thereby improving the stability of its structure. In addition, the end of the barb wire 1 close to the second connecting part 3 is provided with a second guiding portion 16 and a fixing portion 17, so that the connection between the barb wire 1 and the second connecting part 3 is more stable. The second seat body 31 and the third seat body 32 are arranged separately, which facilitates the assembly between the components and avoids over-positioning between the fixing portion 17 and the guiding portion. After the barb wire 1 is assembled, the straightness of the barb wire 1 in its length direction is better.

[0070] Furthermore, the barb wire 1 also includes a second plate 13 , a second guide portion 16 having a hollow inner cavity, a partial section of the second plate 13 is arranged in the inner cavity of the second guide portion 16 , and other sections of the second plate 13 are fixed portions 17 , and the end of the second guide portion 16 is contracted to clamp the second plate 13 .

[0071] That is to say, the fixing portion 17 and the second guide portion 16 are respectively arranged on two different parts, the wire body 11 and the second plate 13. A partial section of the second plate 13 is located in the inner cavity of the second guide portion 16, which can play a role in reinforcing the structure of the second guide portion 16. At the same time, the second plate 13 is clamped by contracting the port of the second guide portion 16, and other connecting parts 35 are not required to connect the second plate 13 and the wire body 11, so as to avoid the connection part 35 from falling off due to corrosion, thereby improving the stability of the structure.

[0072] In addition, the embodiment of the present invention can also set the materials of the second plate 13 and the wire body 11 separately. The second plate 13 can be made of the same material as the wire body 11, or it can be made of a corrosion-resistant material that does not have conductive properties, such as plastic, composite materials, etc.

[0073] The separate arrangement of the second plate 13 and the wire body 11 can more conveniently ensure the structural stability of different components, facilitate the selection of more suitable materials for manufacturing according to the functions of different components, and improve the practicality of the product.

[0074] In some embodiments, the wire body 11 includes a first tube body 111, a first conductive plate 112, a second conductive plate and barbs 18. The first conductive plate 112 and the second conductive plate have arc grooves. The first conductive plate 112 and the second conductive plate are arranged in abutment with each other. The arc grooves on the first conductive plate 112 and the arc groove openings on the second conductive plate are arranged opposite to each other and form an assembly cavity. The first tube body 111 is inserted into the assembly cavity, and a plurality of barbs 18 are arranged on the first conductive plate 112 and / or the second conductive plate.

[0075] The first conductive plate 112 and the second conductive plate are fitted and abutted against each other and fixedly connected by rivet anchors. The first tube body 111 is clamped and fixed in the arc groove between the first conductive plate 112 and the second conductive plate. In order to improve the structural stability, rivets can also be set between the first tube body 111 and the first conductive plate 112, or between the first tube body 111 and the second conductive plate.

[0076] The first tube 111 , the first conductive plate 112 and the second conductive plate may all be made of 304 stainless steel.

[0077] The burrs 18 are fixed to the first conductive plate 112 and the second conductive plate by rivets. The burrs 18 are divided into two groups of burr groups, which are respectively arranged at the two side edges of the first conductive plate 112 and the second conductive plate. Each group of burr groups includes a plurality of burrs 18. The plurality of burrs 18 in each group of burr groups are arranged at intervals along the axial direction of the first tube body 111, and the burrs 18 in the two groups of burr groups are staggered.

[0078] In some embodiments, the first plate 12 has a first column segment 122 at one end close to the wire body 11 , the outer diameter of the first column segment 122 is the same as the inner diameter of the inner cavity of the first guide portion 14 , and the first column segment 122 is inserted into the inner cavity of the first guide portion 14 .

The outer diameter of the second column segment is the same as the inner diameter of the inner cavity of the second guide portion 16 . The second column segment is inserted into the inner cavity of the second guide portion 16 .

[0080] It should be understood that by inserting the first column segment 122 and the second column segment in the first tube body 111, the structural strength of the two ends of the first tube body 111 can be improved. During the rapping process, the stability and service life of the thorn wire 1 can be improved, and the bending, deformation, and even breakage of the two ends of the first tube can be avoided.

[0081] In some embodiments, the barb wire assembly 100 further includes a dust cover, and a dust cover is provided on the outer sides of the first connecting component 2 and the second connecting component 3.

The elastic member 41 is a spring, and the first pull rod 4 can pull the barb wire 1, so that the barb wire 1 is subjected to a pulling force in its length direction, thereby ensuring that the barb wire 1 has sufficient rigidity and can be more stable during the rapping process.

[0083] The electrostatic precipitator of the embodiment of the present invention comprises a shell, a frame 5 and a plurality of barb wire assemblies 100 . The frame 5 is disposed in the shell.

Multiple barb wire assemblies 100 are arranged on the frame 5. The barb wire assembly 100 serves as a cathode. An anode plate is also arranged in the frame 5 to achieve electrostatic precipitator.

[0085] The embodiment of the present invention can not only improve the effect of electrostatic precipitator and the service life of components, and improve the stability of the structure, but also avoid the reduction of dust removal effect due to the breakage of the barb wire 1, and can avoid the short circuit caused by the contact of the barb wire 1 with the anode plate after the breakage.
