[0003] In the existing electrostatic haze removal equipment, the electrode wire is mostly installed in a fixed welding or single bolt fastening mode. Once the electrode wire is loosened due to long-term use or is broken due to vibration or temperature change, adjustment or replacement of the electrode wire needs to disassemble the overall frame, which is complicated to operate and requires professional personnel to work for a long time, thereby increasing the operation difficulty. SUMMARY

[0039] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear and obvious, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0042] Referring to Figures 1 to 8 The haze removal screen provided by the present application will be described. The haze removal screen comprises at least two spaced support frames 100, two anode frames 200 connected between adjacent two support frames 100, the two anode frames 200 being arranged in parallel and spaced apart front and back, and a cathode frame 300 arranged between the two anode frames 200, the two sides of the cathode frame 300 being insulatively connected to the same side support frames 100; a plurality of electrode wires 310 are arranged in the cathode frame 300 in a spaced manner, the upper ends of the electrode wires 310 being connected to the top of the cathode frame 300, and the lower ends of the electrode wires 310 being provided with an adjusting assembly detachably connected to the bottom of the cathode frame 300, the adjusting assembly being used for adjusting the tightness of the electrode wires 310 in the axial direction; a metal wire mesh 210 is arranged in the anode frame 200, and a plurality of connecting bolts 220 are symmetrically arranged on the two sides of the anode frame 200, and the connecting bolts 220 are horizontally connected to the same side support frames 100 in the axial direction.

[0043] Compared with the prior art, in the plurality of connecting bolts 220 symmetrically arranged on the two sides of the anode frame 200, the non-top connecting bolts can be individually detached, when the internal electrode wires 310 need to be operated, only the non-top connecting bolts 220 need to be detached, so that the anode frame 200 can be rotated outward around the top connecting point to be opened, without the need to disassemble the entire support frame 100, and the exposure process of the internal cathode frame 300 is greatly simplified. In the internal cathode frame 300, the adjusting assembly can be directly used to fine-tune the axial tightness of the electrode wires 310, without the need to disassemble the electrode wires 310. In addition, the adjusting assembly is designed to be detachable, when the electrode wires 310 need to be replaced, only the connection between the adjusting assembly and the bottom of the cathode frame 300 needs to be separated, so that the old electrode wires 310 can be quickly removed and new wires can be installed, avoiding the complex process of disassembling the cathode frame 300 to replace the electrode wires 310 in the traditional scheme. The haze removal screen provided by the present application effectively reduces the steps and time of the maintenance operation of the electrode wires 310 through the split connection design and the modular adjustment structure, reduces the technical dependence on professionals, and significantly improves the operation convenience.

[0044] Referring to Figures 3 to 4The support frame 100 is provided with a plurality of support platforms 110 arranged longitudinally at intervals. The cathode frame 300 is provided with a connecting portion 320 extending outward on each side, and the connecting portion 320 is connected to the support platform 110 on the same side through an insulator string 130. The longitudinally arranged support platforms 110 provide the cathode frame 300 with multiple, uniform support points, avoiding the problem of stress concentration and easy tilting of the cathode frame 300 caused by traditional single-point support. At the same time, the cathode frame 300 is connected to the support platform 110 through the outwardly extending connecting portion 320 on both sides, so that the connecting point is closer to the gravity center of the frame, further improving the overall stability of the installed cathode frame 300, effectively resisting external wind and other external force interference, and reducing the risk of structural deformation during long-term use.

[0045] As an insulating medium between the cathode frame 300 and the support frame 100, the insulator string 130 can completely block the current conduction path between the cathode frame 300 and the support frame 100, avoiding the problem of electric leakage and short circuit caused by direct contact between the two. The longitudinal interval design of the support platform 110 provides a clear and fixed mounting point for the connection of the insulator string 130 and the connecting portion 320 of the cathode frame 300, eliminating the need for temporary adjustment of the support position on site, reducing the difficulty of installation and positioning. At the same time, the outwardly extending connecting portion 320 increases the operation space of the cathode frame 300 and the support frame 100, so that the workers can more conveniently access the connecting portion without disassembling the frame body when checking the status of the insulator string 130 or maintaining the cathode frame 300, improving the maintenance efficiency.

[0046] Please refer to Figure 5 The support platform 110 is a H-shaped platform, and the left and right sides of the H-shaped platform are provided with avoidance grooves 111 for avoiding the side edges of the cathode frame 300. The avoidance grooves 111 on the left and right sides of the H-shaped platform avoid the side edges of the cathode frame 300, avoiding the structural interference between the traditional flat support platform 110 and the side edges of the cathode frame 300. When the cathode frame 300 is connected to the support platform 110 through the connecting portion 320, the avoidance grooves 111 can provide accommodation space for the side edges of the cathode frame 300, without the need for additional grinding or adjustment of the frame size, ensuring that the cathode frame 300 can accurately fit the pre-installed position of the support platform 110, reducing the installation deviation caused by structural conflict, and indirectly ensuring the uniformity of the subsequent electrode wire 310 arrangement and the relative position accuracy of the cathode frame 300 and the anode frame 200. The existence of the avoidance grooves 111 increases the operation space of the connecting portion of the cathode frame 300 and the support platform 110. When installing the insulator string 130, the workers do not need to avoid the obstruction of the side edges of the cathode frame 300, and can more smoothly complete the bolt fastening, position adjustment and other operations of the insulator string 130, avoiding the problem of limited tool use caused by narrow space, shortening the installation time of a single connecting structure, and improving the overall construction efficiency.

[0047] In addition, the I-shaped platform itself has a mechanically optimized structure of upper and lower flanges and a middle web, and its bending and shear strength is much higher than that of a flat platform under the same material usage, so that it can stably bear the weight of the cathode frame 300 and the electrode wire 310, and avoid deformation of the platform during long-term use. At the same time, the design of the avoiding groove 111 reduces the material usage of the unnecessary area of the platform under the premise of ensuring the structural strength, realizes weight reduction and material saving, reduces the overall weight of the support frame 100, controls the manufacturing cost, and balances the practicability and economy.

[0048] Please refer to Figures 3 to 4 Each support frame 100 has four support platforms 110 arranged longitudinally at intervals, and each cathode frame 300 has two connection parts 320 arranged at intervals on the upper and lower sides, respectively. The insulator string 130 is connected between the second layer of support platform 110 and the upper connection part 320, and between the fourth layer of support platform 110 and the lower connection part 320. The combination of the four support platforms 110 and the two connection parts 320 forms a two-point support mode, and the support points are located at the second layer and the fourth layer in the longitudinal direction of the support frame 100, so that the stress points of the cathode frame 300 are evenly distributed in the middle and lower regions in the longitudinal direction, avoiding the risk of frame tilting caused by too concentrated support points at the top or bottom. At the same time, two-point support can effectively limit the displacement of the cathode frame 300 in the horizontal and vertical directions, so that even in the face of external wind force and other external force interference, the frame can be stably maintained through the cooperation of the tension of the insulator string 130 and the bearing capacity of the support platform 110, reducing the structural deformation during long-term use, and providing reliable protection for the precise arrangement of the electrode wire 310. The two connection parts 320 arranged at intervals correspond to the second layer and the fourth layer of support platform 110, respectively, so that the longitudinal stress of the cathode frame 300 is evenly distributed to the two support points, avoiding the problem of local overload caused by single-point support, and prolonging the service life of the insulator string 130 and the connection part 320.

[0049] Please refer to Figure 5 The second layer and the fourth layer of support platform 110 are respectively screwed or welded with a mounting tray 120, and the lower end of the insulator string 130 is fixed longitudinally to the upper end surface of the mounting tray 120. Among them, the mounting tray 120 has a mounting plate at the bottom and a connecting plate at the top, the mounting plate is screwed to the support platform 110, and the connecting plate is welded to the upper end of the mounting plate for connecting the lower end of the insulator string 130, so that the insulator string 130 remains in a vertical state. The connection part 320 is a connecting rod welded outside the cathode frame 300, the connecting rod is perpendicular to the side wall of the cathode frame 300, and the upper end of the insulator string 130 is connected vertically to the connecting rod. The double positioning of the upper and lower parts makes the insulator string 130 always remain vertical, avoids the inclination of the cathode frame 300, accurately maintains the electrode spacing, and guarantees the uniformity of the electric field and the dust removal efficiency.

[0050] Please refer to Figure 1 andFigure 7 The facade of the support frame 100 is provided with a protective plate 150; when the support frame 100 is located at the end of the haze removal screen, the protective plate 150 wraps the front and rear facades and the outer lateral facade of the support frame 100; when the support frame 100 is located in the middle of the haze removal screen, the protective plate 150 wraps the front and rear facades of the support frame 100. For the end support frame 100, the protective plate 150 wraps the front and rear facades and the outer lateral facade, which can form a three-sided protective structure. The outer lateral facade directly faces the external environment, which can effectively block the erosion of outdoor wind and sand, rain, debris, etc. on the frame body, and prevent the metal frame from rusting due to long-term exposure. The protection of the front and rear facades can isolate the dust accumulation inside the haze removal screen during operation or the potential interference of the electrode wire 310 during work, and prevent personnel from accidentally touching the end frame to cause safety risks. The middle support frame 100 only needs to wrap the front and rear facades, as the middle position does not need to face the external environment. Therefore, by wrapping the front and rear facades, the unnecessary amount of protective plate 150 can be reduced, the protection and cost balance can be achieved, and material waste can be avoided.

[0051] Preferably, the protective plate 150 is an arc-shaped plate that protrudes outward in the middle. The outward protruding shape of the arc-shaped plate can significantly improve the wind resistance and drainage performance. When facing strong winds, the arc-shaped surface can guide the airflow to flow smoothly along the surface, reducing the impact of wind resistance on the support frame 100, and preventing the frame from shaking or the protective plate 150 from deforming due to the direct impact of wind on the traditional flat protective plate 150. In rainy and snowy weather, the inclined surface of the arc-shaped structure can accelerate the sliding of rainwater and snow, preventing rain and snow from accumulating on the surface of the protective plate 150.

[0052] In addition, compared with a flat plate, the arc-shaped plate that protrudes in the middle can disperse external forces to the entire curved surface, reducing local stress concentration and making it less likely to be damaged by indentation, cracking, etc. This improves the protection ability of the protective plate 150 for the support frame 100. At the same time, the arc-shaped design reduces the joint gaps of the protective plate 150 or reduces the stress deformation of a single plate, making it less likely to crack due to temperature changes or external forces during long-term use, further enhancing the stability and durability of the protection.

[0053] Please refer to Figure 1 and Figure 8The top of the support frame 100 is provided with an upper sealing plate 160, the shape of the upper sealing plate 160 is adapted to the combined cross-sectional shape of the support frame 100 and the protective plate 150. The upper sealing plate 160 can completely cover the gaps and hollow areas on the top of the support frame 100. For the end support frame 100, the adapted upper sealing plate 160 can form a top closed loop protection to prevent rain, dust, fallen leaves and other sundries from penetrating into the inside of the support frame 100 from the top, so as to avoid the rusting or insulation performance degradation of the internal support platform 110 and the connection part 320 of the insulator string 130 due to the accumulation of sundries. For the middle support frame 100, the upper sealing plate 160 can fill the exposed area on the top of the frame to prevent the dust generated during the haze removal process from drifting to the outside of the frame from the top, and to prevent foreign matters from falling into the inside of the frame to interfere with the operation of the electrode wire 310 or the anode frame 200, thereby further improving the overall protection system.

[0054] The upper sealing plate 160 is connected with the support frame 100 by bolts, and can form a transverse constraint on the longitudinal rod on the top of the support frame 100, so as to reduce the shaking or deformation of the top of the frame due to external forces (such as strong wind or slight impact), and indirectly improve the stability of the entire support frame 100. In addition, the integrated and adapted design avoids the misalignment or gap between the traditional special-shaped sealing plate and the frame and the protective plate 150, so that the top appearance of the haze removal screen is more regular and unified, especially in outdoor installation scenes, the visual coordination of the equipment can be improved, and the influence of the disordered top structure on the beauty of the surrounding environment can be avoided.

[0055] Please refer to Figure 6 The adjusting assembly comprises an adjusting screw, the upper end of the adjusting screw is rotationally connected to the lower end of the electrode wire 310, the lower end of the adjusting screw is rotationally connected to the lower end of the cathode frame 300, and the adjusting screw and the electrode wire 310 are coaxial. The coaxial design of the adjusting screw and the electrode wire 310 ensures that the adjusting force is completely transmitted along the axis of the electrode wire 310, avoiding the lateral component force that may be generated by a non-coaxial structure. The coaxial adjustment enables the staff to directly and uniformly change the tension of the electrode wire 310 by rotating the screw, so as to accurately control the electrode wire 310 to be in the best working state and avoid functional abnormalities caused by excessive or insufficient adjustment. At the same time, the rotational connection of the two ends of the screw not only retains the flexibility of adjustment, but also can fix the axial position of the electrode wire 310 after the adjustment is completed, so as to reduce the loosening of the screw caused by equipment vibration or temperature change, and long-term maintain the tension stability of the electrode wire 310.

[0056] Based on the same inventive concept, the present application also provides a construction method of the haze removal screen, comprising the following steps:

[0057] S1: preparation before construction, removing sundries in the construction area and leveling the ground, checking the specifications and quantities of each part of the haze removal screen, checking the completeness of the parts, and preparing construction tools and equipment at the same time;

[0059] S3: cathode frame 300 installation, the lower end of the insulator string 130 is connected to the support platform 110, the upper end of the insulator string 130 is connected to the outwardly extending connecting part 320 on both sides of the cathode frame 300, and the position and verticality of the cathode frame 300 are adjusted;

[0060] S4: electrode line 310 installation and adjustment, a plurality of electrode lines 310 are arranged in the cathode frame 300 according to the design interval, the upper end of the electrode line 310 is connected to the top of the cathode frame 300, and the lower end is installed and adjusted to adjust the axial tightness of the electrode line 310 to a suitable tension state;

[0063] The haze removal screen construction method provided by the present application has the beneficial effects that compared with the prior art, the preparation steps before construction clearly require removing sundries, leveling the ground, checking the specifications, quantities and integrity of the components, and preparing tools and equipment. This step can exclude construction environment interference and component hidden dangers in advance, avoid construction interruption caused by missing tools or component problems, lay a foundation for smooth follow-up construction, and improve overall construction efficiency. The installation of the support frame 100 emphasizes positioning and line laying according to the design drawing, adjusting the perpendicularity and levelness, and then fixing, and checking the position, flatness and strength of the support platform 110, to ensure that the support frame 100 serves as the foundation of the overall structure, the installation position is accurate and the bearing capacity meets the standard, and deviation in the installation of subsequent components caused by frame inclination or unstable support platform 110 is avoided. The installation of the cathode frame 300 connects the support platform 110 and the cathode frame 300 through the insulator string 130, and adjusts the position and perpendicularity, and the installation of the anode frame 200 determines the parallel and spaced arrangement front and back, and adjusts the levelness through the horizontal connection of the connecting bolts 220. The three steps cooperatively guarantee the relative position accuracy of the cathode frame 300, the anode frame 200 and the support frame 100, provide a structural prerequisite for the subsequent function of the electrode wire 310 and the metal wire mesh 210, and reduce the problem of reduced haze removal efficiency caused by installation misalignment. In the electrode wire 310 installation and adjustment step, the adjustment assembly is used to adjust the tightness of the electrode wire 310, without the need for additional disassembly of the structure, the operation is simple and the tension state of the electrode wire 310 can be accurately controlled, and the electrode wire 310 is ensured to be in the best working mode. When the anode frame 200 is installed, the metal wire mesh 210 is first fixed in the frame and then the whole is connected, avoiding the space limitation of installing the frame first and then installing the wire mesh, reducing the operation difficulty, and the horizontal connection of the connecting bolts 220 also provides convenience for subsequent maintenance. The overall debugging and checking step covers component installation correctness, connection firmness, insulation performance, electrical connection state and trial operation observation, and multi-dimensional detection can comprehensively check installation hidden dangers, discover system operation problems in advance through trial operation and correct in time, avoid downtime maintenance caused by hidden faults after formal commissioning, significantly improve the safety and stability of the haze removal screen operation, and prolong the service life of the equipment. The haze removal screen construction method provided by the present application controls step by step, adjusts accurately and detects comprehensively, guarantees the construction quality and efficiency, and provides protection for long-term reliable operation of the equipment, effectively reducing the construction and post-operation and maintenance cost.

[0064] After step S5, according to the end or middle position of the support frame 100 in the haze-removing screen, the corresponding wrapping protective plate 150 is applied to the front and rear vertical surfaces and the outer vertical surface or only the front and rear vertical surfaces of the support frame 100, and the upper sealing plate 160 that is adapted to the combined cross-sectional shape of the support frame 100 and the protective plate 150 is installed at the top of the support frame 100. The end support frame 100 forms a closed-loop protection through the three protective plates 150+adapted upper sealing plate 160, and the middle support frame 100 realizes key area coverage through the front and rear protective plates 150+adapted upper sealing plate 160, thereby finally constructing a comprehensive protection system from the side of the frame to the top. This design can not only block rain, wind, sand, and other foreign matters from penetrating into the support frame 100 from the side or top, thereby avoiding problems such as rusting and insulation performance degradation of the support platform 110 and the insulator string 130 due to foreign matter accumulation or environmental erosion, but also can enhance the overall sealing and stability of the support frame 100 through the adaptive structure, thereby providing protection for the long-term and reliable operation of the core components of the haze-removing screen.

[0065] If the electrode wire 310 is loose or broken, any non-top connecting bolt 220 on both sides of the anode frame 200 is removed, the anode frame 200 is rotated outward around the connecting bolt 220 at the top of both sides of the anode frame 200 as the pivot, the loose electrode wire 310 is adjusted through the adjusting assembly to achieve a suitable tension state, or the connection between the broken electrode wire 310 and the top and bottom of the cathode frame 300 is removed, a new electrode wire 310 is installed, the upper end of the electrode wire 310 is installed first, then the lower end of the electrode wire 310 is installed, and the axial tightness of the electrode wire 310 is adjusted to a suitable tension state through the adjusting assembly, and after the electrode wire 310 is tensioned or replaced, the anode frame 200 is rotated inward around the connecting bolt 220 at the top of both sides of the anode frame 200 as the pivot, and the installation of the non-top connecting bolt 220 on both sides of the anode frame 200 is sequentially completed from top to bottom.

[0066] Specifically, the staff does not need to disassemble the overall frame of the haze-removing screen, only needs to remove the non-top connecting bolt 220 on both sides of any anode frame 200, and rotates the anode frame 200 outward around the connecting bolt 220 at the top of both sides of the anode frame 200 as the pivot to open, thereby quickly exposing the internal cathode frame 300 and the electrode wire 310, and avoiding problems such as complex operation and long time caused by overall disassembly in the traditional scheme.

[0067] For different fault scenarios, the process design further simplifies the operation. If the electrode wire 310 is loose, the axial tightness of the electrode wire 310 can be adjusted to a suitable tension state directly through the adjusting assembly without disassembling the electrode wire 310 body. If the electrode wire 310 is broken, only the connection of the broken electrode wire 310 with the top and bottom of the cathode frame 300 needs to be removed, the new electrode wire 310 is installed in the order of first installing the upper end and then installing the lower end, and then the tightness is fine-tuned through the adjusting assembly. After the maintenance is completed, the anode frame 200 is rotated inward and reset with the top connecting bolt 220 as the pivot, and then the two side non-top connecting bolts 220 are installed in turn from top to bottom. This can not only ensure that the anode frame 200 is connected firmly with the support frame 100 and the levelness meets the standard, but also quickly restore the overall structural stability of the equipment, significantly shorten the maintenance time, and reduce the impact on the normal operation of the haze removal screen.

[0068] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
