[0002] Hydraulic metal structures generally refer to various metal components and equipment used in water conservancy projects. Specifically, they can be categorized as follows: gates and opening / closing devices, including planar gates, arc gates, and miter gates, as well as their associated hoists; pressure steel pipes; steel pipes used to transport high-pressure water, typically made of low-alloy steel such as Q345B, with wall thickness designed according to water pressure; trash racks; and filter devices composed of metal bars, with bar spacing typically ranging from 50-200mm, mostly made of stainless steel or hot-dip galvanized steel. Since hydraulic metal structures are mostly immersed in water for extended periods during use, anti-corrosion coating is an essential treatment process to ensure their service life.

[0003] However, due to the limitations of existing spraying technology, automatic spraying equipment often suffers from problems such as excessive dead corners in the spraying of trash racks and difficulty in improving spraying quality when spraying multi-plate structures such as trash racks due to its own flat spraying limitations and lack of adaptive adjustment technology.

[0011] Preferably, the auxiliary roller frame includes a first auxiliary frame, with a plurality of movable rollers arranged and fitted inside one side of the first auxiliary frame, and a pin fixed inside the other end of the first auxiliary frame that is movably fitted to the top structure of the spraying platform.

The bottom of the recycling bin is provided with an assembly space that is not connected to its own space. An electric heating plate is installed in the assembly space.

[0014] Preferably, the treatment process of the anti-corrosion treatment equipment for hydraulic metal structures includes the following steps; S1, Surface pretreatment The trash rack body to be coated with anti-corrosion paint undergoes a series of surface treatments, including sandblasting and power tool rust removal, in order to achieve the specified surface cleanliness and roughness. S2, Cleaning treatment Solvent cleaning is used, followed by scrubbing or spray cleaning with an alkaline cleaning agent. After completion, rinse two to three times with clean fresh water and then dry. S3, Painting Preparation; Before painting, the quality of the surface pretreatment of the trash rack body shall be inspected. Only after it passes the inspection can the painting be carried out. When painting, the relative humidity of the ambient air should be lower than 85% or the surface temperature of the base metal should be no less than three degrees above the dew point. S4. Coating Application The first step is to place the trash rack body on the support platform formed by splicing two auxiliary roller frames and align and straighten it relative to the top structure of the spraying platform; The second step is to connect the conduit of the existing paint pumping device to the spraying assembly. At this time, the spraying assembly is in a vertical position relative to the top of the spraying platform. The second screw travel mechanism is activated. The second screw travel mechanism reciprocates to drive the angle adjustment assembly and the spraying assembly to move left and right at the corresponding positions on the trash rack body. Then, the spraying assembly automatically sprays the paint onto the surface of the corresponding position on the trash rack body. The third step involves pausing the transmission output of the second lead screw travel mechanism after the angle adjustment component and the spraying component have completed one cycle of reciprocating motion. Then, the first lead screw travel mechanism is activated, which drives the adjustment bracket, the second lead screw travel mechanism, the angle adjustment component, and the spraying component to move automatically forward or backward until the spraying component moves to the area near the trash rack body to be processed. Once this is completed, the transmission output of the first lead screw travel mechanism is paused, and the operation of the second step is repeated. After this is completed, the operation of the third step is repeated. By repeating this process, the trash rack body can be fully automated for anti-corrosion spraying. Step 4; Considering that the internal plate-like structure of the trash rack is in a vertical position and the need to further enhance the coating effect, after a full coating of the trash rack body, the spraying angle of the spraying component is adjusted using the angle adjustment component. The specific operation is as follows: The second motor component inside the angle adjustment assembly outputs a transmission gear shaft, which then actively engages with the transmission gear ring until the gear ring drives the spraying assembly to rotate forward to the specified angle via the composite cylinder. After completion, the transmission output of the second motor component is paused. Then, following the operation steps one to three above, the spraying assembly performs a fully automatic spraying of the trash rack body in a relatively tilted state. After completion, the second motor component inside the angle adjustment assembly outputs a transmission gear shaft, which then actively engages with the transmission gear ring until the gear ring drives the spraying assembly to rotate in the reverse direction to the specified angle via the composite cylinder. After completion, the transmission output of the second motor component is paused. Then, following the operation steps one to three above, the spraying assembly performs a fully automatic spraying of the trash rack body in a relatively tilted state. Once all the above steps are completed, a comprehensive and thorough high-quality spraying process can be performed on the trash rack body.

[0015] The present invention has the following beneficial effects: 1. This anti-corrosion treatment equipment for hydraulic metal structures uses an angle adjustment component as a support for the spraying component and for rotational adjustment. In subsequent use in conjunction with the adjustment bracket, the first screw travel mechanism, and the second screw travel mechanism, the spraying component can perform fully automated spraying of the trash rack body in the form of flat spraying and continuous oblique spraying at a specified tilt angle. This significantly improves the quality of anti-corrosion spraying and enables adaptive spraying of structures such as trash rack bodies, solving the problems existing in the prior art.

[0016] 2. This anti-corrosion treatment equipment for hydraulic metal structures, with its two auxiliary roller frames, two fourth-brake servo motors, and two clamping components working in tandem, provides convenient conveying, adjustment, and stable support during the initial placement of the trash rack body. After the trash rack body is placed, the two clamping components automatically clamp and suspend the trash rack body, while the two auxiliary roller frames are rotated and stored near the inner side wall of the spraying platform by their respective fourth-brake servo motors, away from the spraying area of ​​the spraying components. This prevents the paint from causing the rolling of the moving rollers inside the auxiliary roller frames to become stuck, thus extending the service life of the auxiliary roller frames.

[0017] 3. This anti-corrosion treatment equipment for hydraulic metal structures provides collection conditions through a set recycling bin and lifting components, thereby collecting excess paint that leaks out from the inside of the trash rack body and is scattered disorderly during the spraying process. This avoids polluting the processing environment. At the same time, the electric heating plate set in the recycling bin can also heat the paint inside the recycling bin, turning it from a solid to a liquid state, which facilitates further recycling and reduces processing costs.

[0018] 4. The anti-corrosion treatment process of this hydraulic metal structure anti-corrosion treatment equipment, through the dual effects of thorough pre-treatment cleaning and highly automated spraying, can significantly improve the processing quality of the anti-corrosion spraying of the trash rack body, ensuring that the trash rack body has a long-term and effective service condition.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Please see Figures 1-4 The present invention provides a technical solution: a corrosion protection device for hydraulic metal structures, including a spraying platform 1, two opposing auxiliary roller frames 2 are fitted inside the top of the spraying platform 1, and the top structures of the two auxiliary roller frames 2 are aligned to form a support platform and support a trash rack body 12. An adjusting bracket 3 is fitted on the outside of the trash rack body 12. A first screw travel mechanism 5 and a guide structure 6 are respectively connected to the two sides of the bottom of the adjusting bracket 3. The first screw travel mechanism 5 and the guide structure 6 are respectively installed on the two sides of the top of the spraying platform 1, and the first screw travel mechanism 5 and the guide structure 6 cooperate to drive the adjusting bracket 3, so that the adjusting bracket 3 can automatically move back and forth. The first lead screw travel mechanism 5 includes a first lead screw 51, a first nut 52, and a first brake servo motor 53. The ends of the first lead screw 51 are fitted with bearing seats mounted on the top of the spraying platform 1 via bearing sleeves. The first brake servo motor 53 is mounted on the top of the spraying platform 1 and is connected to one end of the first lead screw 51. The first nut 52, as the output structure of the first lead screw travel mechanism 5, is threadedly connected to the surface of the first lead screw 51 and is connected to the bottom structure on one side of the adjusting bracket 3. The guide structure 6 includes a first guide rod 61 and a guide sleeve 62. The ends of the first guide rod 61 are fixedly fitted with top support seats mounted on the spraying platform 1. The guide sleeve 62, as the output structure of the guide structure 6, is snapped onto the surface of the first guide rod 61 and is then connected to the bottom structure on the other side of the adjusting bracket 3. The combined transmission of the first lead screw travel mechanism 5 and the guide structure 6 enables the adjusting bracket 3 and related structures on the adjusting bracket 3 to automatically move back and forth on the top of the spraying platform 1. The outer side of the first lead screw traveling mechanism 5 and the outer side of the guide structure 6 are both fitted with the second auxiliary frame 4 on the top of the spraying platform 1. The top of the second auxiliary frame 4 is provided with a sliding groove. The bottom structures on both sides of the adjusting bracket 3 are slidably installed on the top of the two second auxiliary frames 4 respectively. Thus, in addition to using the second auxiliary frame 4 as an outer protective structure for the first lead screw traveling mechanism 5 or the guide structure 6, the two second auxiliary frames 4 can also provide further stable support for the adjusting bracket 3 in subsequent reciprocating movement, thereby improving the reliability and stability of the adjusting bracket 3 during the movement process. The top of the adjusting bracket 3 is equipped with a second lead screw traveling mechanism 7. The output structure of the second lead screw traveling mechanism 7 is connected to the angle adjusting component 8. The second lead screw traveling mechanism 7 can automatically move the angle adjusting component 8 left and right. The bottom of the angle adjusting component 8 is equipped with a spraying component 9. The angle adjusting component 8 can automatically adjust the output angle of the spraying component 9. The angle adjusting component 8 includes a composite cylinder frame 81, a gear ring 82, a gear shaft 83, and a second motor component 84. One end of the composite cylinder frame 81 is fitted onto the output structure surface of the second lead screw traveling mechanism 7. The gear ring 82 and the gear shaft 83 mesh with each other and are respectively fixedly sleeved inside the composite cylinder frame 81 and movably sleeved inside the composite cylinder frame 81. The output structure of the second motor component 84 is connected to the middle part of the gear shaft 83. The second lead screw travel mechanism 7 includes a second lead screw 71, a second nut 72, and a first motor component 73. The second nut 72 serves as the output structure of the second lead screw travel mechanism 7 and is threadedly connected to the surface of the second lead screw 71. The surface of one end of the second nut 72 is fitted with the internal structure of one end of the composite cylinder frame 81 through a bearing. Both ends of the second lead screw 71 are fitted with auxiliary bearing seats mounted on the top of the adjusting bracket 3 through bearings. The first motor component 73 is mounted on the top surface of the adjusting bracket 3 and includes a second brake servo motor and a first reducer. The output end of the second brake servo motor is connected to the input end of the reducer, and the output end of the reducer is connected to one end of the second lead screw 71. The second lead screw travel mechanism 7 enables the angle adjustment component 8 to automatically reciprocate in the left and right directions on the top of the spraying platform 1, thereby meeting the requirements for automated and comprehensive spraying of the trash rack body 12, ensuring spraying quality while improving work efficiency. The second motor component 84 includes a third brake servo motor and a second reducer. The output end of the third brake servo motor is connected to the input end of the reducer, and the output end of the reducer is connected to one end of the gear shaft 83. The housing of the reducer and the housing of the third brake servo motor are both mounted with an auxiliary bracket fixed to the top surface of the second nut 72. The spraying component 9 includes an extension plate and a nozzle body mounted on one end of the extension plate. The other end of the extension plate is fixed to the bottom surface of the composite cylinder frame 81. The angle adjustment component 8 can automatically adjust the spraying output angle of the spraying component 9, thereby adapting to the structural spraying requirements of the trash rack body 12, reducing the spraying dead angle area, and improving the spraying quality.

[0023] The treatment process of the anti-corrosion treatment equipment for hydraulic metal structures includes the following steps; S1, Surface pretreatment The trash rack body 12 to be coated with anti-corrosion coating undergoes a series of surface treatments, including sandblasting and power tool rust removal, in order to achieve the specified surface cleanliness and roughness. S2, Cleaning treatment Solvent cleaning is performed, such as using gasoline. Then, alkaline cleaning agents are used for wiping or spraying, such as a solution of sodium hydroxide, sodium carbonate, triuranium phosphate and uranium silicate in a certain proportion. After completion, rinse two to three times with clean fresh water and then dry. S3, Painting Preparation; Before painting, the quality of the surface pretreatment of the trash rack body 12 shall be inspected. Only after it is qualified can the painting be carried out. When painting, the relative humidity of the ambient air should be lower than 85% or the surface temperature of the base metal should be not lower than three degrees above the dew point. S4. Coating Application The first step is to place the trash rack body 12 on the support platform formed by splicing two auxiliary roller frames 2 and align and straighten it relative to the top structure of the spraying platform 1; The second step is to connect the conduit of the existing paint pumping device to the spraying component 9. At this time, the spraying component 9 is in a vertical state relative to the top of the spraying platform 1. The second screw travel mechanism 7 is activated. The second screw travel mechanism 7 reciprocates to drive the angle adjustment component 8 and the spraying component 9 to move left and right at the corresponding positions of the trash rack body 12. Then, the spraying component 9 automatically sprays the paint onto the surface of the corresponding position of the trash rack body 12. The specific transmission principle of the second lead screw travel mechanism 7 is as follows: the second brake servo motor inside the first motor component 73 drives the second lead screw 71 to rotate synchronously through the first reducer. Then, by utilizing the reciprocating meshing between the second lead screw 71 and the second nut 72, the second nut 72 drives the angle adjustment component 8 and the spraying component 9 to perform reciprocating linear displacement. The third step is to pause the transmission output of the second lead screw travel mechanism 7 after the angle adjustment component 8 and the spraying component 9 have moved back and forth for one cycle, and then start the first lead screw travel mechanism 5. The first lead screw travel mechanism 5 drives the adjustment bracket 3, the second lead screw travel mechanism 7, the angle adjustment component 8 and the spraying component 9 to move forward or backward automatically until the spraying component 9 moves to the area near the processing area of ​​the trash rack body 12. After completion, pause the transmission output of the first lead screw travel mechanism 5 and repeat the operation of the second step. After completion, repeat the operation of the third step. By repeating this process, the trash rack body 12 can be fully automated for anti-corrosion spraying. The specific transmission principle of the first lead screw traveling mechanism 5 is as follows: the first brake servo motor 53 drives the first lead screw 51 to rotate synchronously, and then the reciprocating meshing between the first lead screw 51 and the first nut 52 is used to drive the first nut 52 to drive the assembly formed by the adjusting bracket 3, the angle adjusting component 8, the spraying component 9 and other structures to perform reciprocating linear displacement. Step 4; Considering that the internal plate-like structure of the trash rack body 12 is in a vertical state and the need to further enhance the spraying effect, after the trash rack body 12 is fully sprayed, the spraying angle of the spraying component 9 is adjusted by the angle adjustment component 8. The specific operation is as follows: The second motor component 84 inside the angle adjustment assembly 8 outputs a transmission gear shaft 83, which then actively engages the transmission gear ring 82 until the gear ring 82 drives the spraying assembly 9 to rotate forward to a specified angle via the composite cylinder frame 81. After completion, the transmission output of the second motor component 84 is paused. Then, following the operation steps one to three above, the spraying assembly 9 performs a fully automatic spraying of the trash rack body 12 in a relatively tilted state. After completion, the second motor component 84 inside the angle adjustment assembly 8 outputs a transmission gear shaft 83, which then actively engages the transmission gear ring 82 until the gear ring 82 drives the spraying assembly 9 to rotate in the opposite direction to a specified angle via the composite cylinder frame 81. After completion, the transmission output of the second motor component 84 is paused. Then, following the operation steps one to three above, the spraying assembly 9 performs a fully automatic spraying of the trash rack body 12 in a relatively tilted state. After all the above steps are completed, a comprehensive and thorough high-quality spraying process can be performed on the trash rack body 12.

[0024] Example 2 Please see Figures 1-6 Both sides of the top of the adjusting bracket 3 are provided with arc-shaped grooves 10, and the center of the arc-shaped grooves 10 coincides with the rotation center of the composite cylinder frame 81. T-shaped tubes 11 are installed on the surface of the extended support plate. The two ends of the T-shaped tubes 11 pass through the two arc-shaped grooves 10 respectively and are fixed with flange structures. During the rotation adjustment of the composite cylinder frame 81, the T-shaped tubes 11 can be rotated and adjusted in the same center within the arc-shaped clearance space formed by the two arc-shaped grooves 10.

[0025] When in use, considering the convenience of connecting the existing paint pumping device's conduit to the spray nozzle body inside the spraying assembly 9 and the clearance requirements during the treatment process of the anti-corrosion treatment equipment for hydraulic metal structures, the T-shaped pipe 11 is used as a conveying channel to provide rigid support and sliding clearance for the spraying assembly 9. This further improves the stability of the spraying assembly 9 during spraying and reduces the probability of the paint pumping device's conduit being entangled and interfered with by structures such as the spraying platform 1, without interfering with the rotation and adjustment of the spraying assembly 9.

[0026] Example 3 Please see Figures 1-7The auxiliary roller frame 2 includes a first auxiliary frame 21. Several movable rollers 22 are arranged and fitted inside one side of the first auxiliary frame 21. A pin is fixed inside the other end of the first auxiliary frame 21 and is movably fitted to the top structure of the spraying platform 1. One end of the pin is connected to a fourth brake servo motor 14 installed on the front surface of the spraying platform 1. The fourth brake servo motor 14 can automatically rotate and adjust the corresponding auxiliary roller frame 2 inside the spraying platform 1 through the pin. Limiting holes 17 are opened on the front and rear surfaces of the first auxiliary frame 21. A third electric push rod 18 that can automatically fit into the limiting holes 17 is installed on the top of the spraying platform 1. The spraying platform 1 is equipped with clamping components 13 at both the front and rear ends of the top. The output structure of the two clamping components 13 can clamp and support the trash rack body 12. The clamping components 13 include clamping plates 131, protective covers 132 and first electric push rods 133. The output end of the first electric push rod 133 is connected to the side of the clamping plate 131 away from the trash rack body 12. The protective cover 132 is connected to the output end of the first electric push rod 133 and is movably sleeved with the housing structure of the first electric push rod 133. A positioning support is installed between the housing surface of the first electric push rod 133 and the top of the spraying platform 1. The two clamping plates 131 can clamp and support the trash rack body 12 under the transmission of their respective first electric push rods 133.

[0027] During use, considering that the two auxiliary roller frames 2 are prone to jamming due to excess paint leaking from the inside of the trash rack body 12 during the treatment process of the anti-corrosion treatment equipment for hydraulic metal structures, the two auxiliary roller frames 2 are adjusted by the fourth brake servo motor 14, clamping components 13 and other structures, as follows: When the process of the anti-corrosion treatment equipment for hydraulic metal structures is carried out to the point where the trash rack body 12 is placed on top of the two auxiliary roller frames 2 and aligned and adjusted, the first electric push rod 133 inside the two clamping components 13 is activated. The two first electric push rods 133 drive their respective corresponding clamping plates 131 to clamp and support the trash rack body 12 from the front and back, thereby suspending the trash rack body 12 in the top space of the spraying platform 1. After the trash rack body 12 is suspended and clamped, the third electric push rod 18 set on the front and rear ends of the auxiliary roller frame 2 is closed until the output end of the third electric push rod 18 is disengaged from the limiting hole 17 fitted on itself. Then, the two fourth brake servo motors 14 are started, so that the output ends of the two fourth brake servo motors 14 drive their respective auxiliary roller frames 2 through their respective pins until the two auxiliary roller frames 2 rotate and are stored inside the spraying platform 1. The two auxiliary roller frames 2 are close to the inner walls on both sides of the spraying platform 1, thereby preventing the movable rollers 22 inside the two auxiliary roller frames 2 from being covered by paint and ensuring the flexibility of movement.

[0028] Example 4 Please see Figures 1-7 The spraying platform 1 is internally equipped with a recycling bin 15 and a lifting assembly 16. The lifting assembly 16 includes a second electric push rod 161. The output end of the second electric push rod 161 is connected to the bottom of the recycling bin 15. The bottom of the recycling bin 15 is fixed with a second guide rod 162 on both sides. One end of the second guide rod 162 is engaged with a positioning sleeve plate 163 fixed on the inner wall of the spraying platform 1. The bottom of the recycling bin 15 is provided with an assembly space that is not connected to its own space. An electric heating plate 19 is installed in the assembly space.

[0029] During use, considering the problem that excess coating leaking from the inside of the trash rack body 12 can easily scatter disorderly on the two auxiliary roller frames 2 during the treatment process of the anti-corrosion treatment equipment for hydraulic metal structures, the collection conditions are provided by the set up recycling box 15 and lifting component 16. The specific operation is as follows: After the two auxiliary roller frames 2 are rotated and stored inside the spraying platform 1, the second electric push rod 161 is activated. The output end of the second electric push rod 161 drives the recycling box 15 to move automatically upward until the maximum stroke of the second electric push rod 161. During the movement of the recycling box 15, the second guide rod 162 and the positioning sleeve plate 163 are engaged with each other to provide guidance and support. Thus, the recycling box 15 is used to collect the excess paint that falls from the trash rack body 12 during the spraying process. After a certain amount is collected, the electric heating plate 19 is turned on to heat the paint inside the recycling box 15, causing it to change from a solid to a liquid state for centralized collection.

10. A treatment process for a corrosion protection device for hydraulic metal structures as described in claim 1, characterized in that: Includes the following steps; S1, Surface pretreatment The body of the anti-corrosion sprayed trash rack (12) is subjected to a series of surface treatments, including sandblasting and power tool rust removal, in order to achieve the specified surface cleanliness and roughness. S2, Cleaning treatment Solvent cleaning is used, followed by scrubbing or spray cleaning with an alkaline cleaning agent. After completion, rinse two to three times with clean fresh water and then dry. S3, Painting Preparation; Before painting, the quality of the surface pretreatment of the trash rack body (12) shall be inspected. Only after it is qualified can the painting be carried out. When painting is carried out, the relative humidity of the ambient air should be lower than 85% or the surface temperature of the base metal should be not lower than three degrees above the dew point. S4. Coating Application The first step is to place the trash rack body (12) on the support platform formed by splicing two auxiliary roller frames (2) and align and straighten it relative to the top structure of the spraying platform (1); The second step is to connect the conduit of the existing paint pumping device to the spraying assembly (9), and at this time the spraying assembly (9) is in a vertical state relative to the top of the spraying platform (1). The second screw travel mechanism (7) is activated, and the second screw travel mechanism (7) reciprocates to drive the angle adjustment assembly (8) and the spraying assembly (9) to move left and right at the corresponding positions of the trash rack body (12), so that the spraying assembly (9) automatically sprays the paint onto the surface of the corresponding position of the trash rack body (12). The third step is to pause the transmission output of the second lead screw travel mechanism (7) after the angle adjustment component (8) and the spraying component (9) have moved back and forth for one cycle, and start the first lead screw travel mechanism (5). The first lead screw travel mechanism (5) drives the adjustment bracket (3), the second lead screw travel mechanism (7), the angle adjustment component (8) and the spraying component (9) to move forward or backward automatically until the spraying component (9) moves to the area near the trash rack body (12) to be processed. After completion, pause the transmission output of the first lead screw travel mechanism (5) and repeat the operation of the second step. After completion, repeat the operation of the third step. By repeating this process, the trash rack body (12) can be fully automated for anti-corrosion spraying. Step 4; Considering that the internal plate structure of the trash rack body (12) is in a vertical state and the spraying effect needs to be further enhanced, after the trash rack body (12) is fully sprayed, the spraying angle of the spraying component (9) is adjusted by the angle adjustment component (8). The specific operation is as follows: The second motor component (84) inside the angle adjustment assembly (8) outputs the transmission gear shaft (83), which then actively engages the transmission gear ring (82) until the gear ring (82) drives the spraying assembly (9) to rotate forward to the specified angle via the composite cylinder frame (81). After completion, the transmission output of the second motor component (84) is paused. Then, following the operation of the first to third steps above, the spraying assembly (9) performs a full automatic spraying of the trash rack body (12) in a relatively tilted state. After completion, the second motor component inside the angle adjustment assembly (8) outputs the transmission gear shaft (83), which then engages the transmission gear ring (82) to the specified angle. The component (84) outputs the transmission gear shaft (83), which then actively engages the transmission gear ring (82) until the gear ring (82) drives the spraying assembly (9) to rotate in the opposite direction to the specified angle through the composite cylinder frame (81). After completion, the transmission output of the second motor component (84) is paused. Then, following the operation of the first to third steps above, the spraying assembly (9) performs a full automatic spraying of the trash rack body (12) in a relatively tilted state. After all the above steps are completed, the trash rack body (12) can be fully and thoroughly sprayed with high quality.
