Description

Technical Field

[0001] This utility model relates to the technical field of nuclear power plant interceptor cleaning equipment, and more specifically, to an interceptor cleaning operation platform. Background Technology

[0002] The water intake system of a nuclear power plant is crucial for ensuring the cooling needs of the units. To prevent marine organisms, silt, and other contaminants from entering the intake pipes and causing blockages, equipment wear, or reduced heat exchange efficiency, domestic nuclear power plants generally use interception nets at the intake points. However, these nets are prone to blockage by marine organisms, silt, and other deposits over long-term operation. If the blockage exceeds a certain threshold, it can lead to insufficient water intake flow, affecting unit cooling and even causing unplanned shutdowns. Therefore, regular cleaning or replacement is necessary.

[0003] Currently, domestic nuclear power plants mainly carry out the cleaning and replacement of interceptor nets using traditional methods: workers dispatch cleaning vessels to the work area, equipping them with winches, cranes, and other equipment to lift the nets to the surface for washing; simultaneously, divers use handheld high-pressure washing equipment to clean the underwater portion of the nets. While this method meets basic operational and maintenance needs, it has significant shortcomings.

[0004] First, the operation is inefficient. Because the interception net is a flexible structure, it easily wrinkles and stacks when rolled out of the water, making it difficult to unfold effectively. Cleaning must be done section by section, and the net's posture needs to be adjusted after each section is cleaned. Furthermore, the surface and underwater cleaning must be carried out in stages, resulting in gaps in the process and overall low efficiency. Second, the operation is risky. Underwater cleaning relies on manual operation by divers. When divers operate with high-pressure flushing equipment, they face complex water currents and low visibility, significantly increasing safety risks. Third, the operation is physically demanding. Current methods require a large amount of manual labor for equipment operation and flushing, and the low efficiency leads to long operation times and high labor intensity. Utility Model Content

[0005] The purpose of this utility model is to provide a platform for replacing and cleaning interceptor nets, so as to solve the technical problems of low cleaning efficiency, high operation risk and high operation intensity of existing interceptor net cleaning devices.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Firstly, a platform for replacing and cleaning a netting interceptor is provided, comprising:

[0008] Work platform;

[0009] The water-based cleaning mechanism includes a first gantry connected to the work platform and a first flushing device mounted on the first gantry. The first gantry is located on the water and is used to open the water-based portion of the interception net. The first flushing device is used to flush the water-based portion of the interception net.

[0010] The underwater cleaning mechanism includes a second gantry connected to the working platform and a second flushing device disposed on the second gantry. The second gantry is located underwater and is used to open the underwater portion of the interception net. The second flushing device is used to flush the underwater portion of the interception net. A traction device is disposed on the working platform and is used to sequentially traction the interception net onto the second gantry and the first gantry or to release the interception net from the second gantry and the first gantry into the underwater environment.

[0011] By using the second gantry and the first gantry to open the underwater and above-water sections of the interception net respectively, the problem of the net bag being unable to unfold due to its folds and stacking in traditional cleaning is solved. This eliminates the need for segment-by-segment flushing operations, significantly improving cleaning efficiency. Underwater cleaning is completed by the second flushing device, eliminating the need for divers to operate the equipment manually and completely eliminating the safety risks of diving operations. The entire cleaning and replacement process is carried out through the mechanized coordinated operation of the traction device, gantry, and flushing device, reducing manual operation steps and lowering the labor intensity of operators.

The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0045] like Figures 1 to 3 As shown in the figure, an embodiment of this utility model provides a barrier net replacement and cleaning operation platform, comprising:

[0046] Work platform 1;

[0047] The water cleaning mechanism 2 includes a first gantry 22 connected to the work platform 1 and a first flushing device 23 disposed on the first gantry 22. The first gantry 22 is located on the water and is used to open the water portion of the interception net 10. The first flushing device 23 is used to flush the water portion of the interception net 10.

[0048] The underwater cleaning mechanism 3 includes a second gantry 31 connected to the working platform 1 and a second flushing device 32 disposed on the second gantry 31. The second gantry 31 is located underwater and is used to open the underwater part of the interception net 10. The second flushing device 32 is used to flush the underwater part of the interception net 10.

[0049] The towing device 21 is located on the working platform 1. The towing device 21 is used to tow the interception net 10 to the second gantry 31 and the first gantry 22 in sequence or to release the interception net 10 from the second gantry 31 and the first gantry 22 into the water.

[0050] Specifically, the structure of the interception net 10 replacement cleaning operation platform is based on the working platform 1 as the basic load-bearing component, integrating three major functional modules: the water surface cleaning mechanism 2, the underwater cleaning mechanism 3, and the traction device 21. The water surface cleaning mechanism 2 includes a first gantry 22 connected to the working platform 1 and located in the water area, and a first flushing device 23 mounted on the first gantry 22. The underwater cleaning mechanism 3 consists of a second gantry 31 connected to the working platform 1 and located underwater, and a second flushing device 32 mounted on the second gantry 31. The components form a coordinated overall system.

[0051] like Figure 4 and Figure 5As shown, the interceptor net replacement and cleaning operation platform provided in this embodiment: When carrying out the cleaning operation of the interceptor net 10, the traction device 21 provides power to gradually pull the interceptor net 10 to be cleaned from underwater to the second gantry 31 underwater. At this time, the second gantry 31 expands the underwater part of the interceptor net 10 to keep the net in a stretched state for easy rinsing. Simultaneously, the second rinsing device 32 is activated to rinse the underwater part of the expanded interceptor net 10. The high-pressure water jet generated by the second rinsing device 32 creates a micro-explosion phenomenon underwater, which can significantly improve the impact force of underwater rinsing and effectively remove stubborn deposits on the interceptor net 10. With the continuous traction of the traction device 21, The interception net 10 is further pulled to the position of the first gantry 22 on the water. The first gantry 22 then opens up the water-surface part of the interception net 10. The first flushing device 23 is simultaneously activated to flush the water-surface part of the interception net 10 again, realizing the continuous connection between underwater and water-surface cleaning and repeated cleaning operations, ensuring and improving cleaning quality and efficiency. When the cleaning operation of the interception net 10 is completed and it needs to be replaced, the traction device 21 operates in reverse, gradually releasing the cleaned interception net 10 from the second gantry 31 and the first gantry 22 into the water. During the release process, the second gantry 31 first assists in opening and positioning the water-surface part of the interception net 10 to ensure that the interception net 10 is accurately installed in place.

[0052] Based on this, the underwater and above-water portions of the interception net 10 are opened by the second gantry 31 and the first gantry 22 respectively, solving the problem of the net bag being unable to unfold due to its folds and stacking in traditional cleaning. This eliminates the need for segmented flushing operations, significantly improving cleaning efficiency and effectiveness. Underwater cleaning is completed by the second flushing device 32, eliminating the need for divers to operate the equipment manually and completely eliminating the safety risks of diving operations. The entire cleaning and replacement process is carried out through the mechanized coordinated operation of the traction device 21, the gantry, and the flushing device, reducing manual operation steps and lowering the labor intensity of operators. At the same time, it realizes integrated online operation of cleaning and replacement, effectively improving operational efficiency while reducing the frequency of net replacement, and ensuring the safety and economy of the operation and maintenance of the nuclear power plant's water intake system.

[0053] Preferably, the pressures of the high-pressure water jets generated by the first flushing device 23 and the second flushing device 32 are different. Based on this, by setting the first flushing device 23 and the second flushing device 32 with different flushing pressures, the intercepting net 10 is flushed sequentially under different flushing pressures, thereby achieving graded high-pressure flushing of the intercepting net 10, which can meet the cleaning needs of different deposits and further improve the cleaning quality.

[0054] Specifically, the surface cleaning mechanism 2 and the underwater cleaning mechanism 3 can be configured with one, two, three, etc., as needed, and this application embodiment does not impose any restrictions on this.

[0055] Please refer to it again. Figures 1 to 3In one embodiment, the first gantry 22 includes a first support rod 221, a second support rod 222 connected to the first support rod 221, and a first gantry drive structure 223 for driving the first support rod 221 to rotate about an axis. The first support rod 221 is axially connected to the working platform 1. The first gantry drive structure 223 connects the working platform 1 and the first support rod 221 and drives the first support rod 221 to rotate about an axis, making the pitch angle of the first support rod 221 adjustable. The second support rod 222 is arranged parallel to the working surface of the working platform 1 and is used to support the above-water portion of the interception net 10. Specifically, the first support rod 221 rotates about an axis parallel to the working platform 1 to ensure the range of continuous adjustment of the pitch angle of the first support rod 221 in the vertical plane.

[0056] Specifically, the first gantry 22 structure of the interception net replacement and cleaning operation platform includes a first support rod 221, a second support rod 222, and a first gantry drive structure 223. The first support rod 221 is rotatably supported by the working platform 1 through a shaft connection. The second support rod 222 is fixedly connected to the first support rod 221 and maintains a spatial posture parallel to the working surface of the working platform 1. The first gantry drive structure 223 is installed on the working platform 1 and connected to the first support rod 221. It provides torque output through hydraulic drive or mechanical transmission to drive the first support rod 221 to rotate relative to the working platform 1.

[0057] Based on this, when the interception net 10 is transported to the water operation area by the traction device 21, the first gantry drive structure 223 drives the first support rod 221 to rotate around the axis, thereby realizing continuous adjustment of the pitch angle of the first support rod 221 in the vertical plane (the adjustment range can cover the optimal support angle required for the unfolding of the interception net 10), so that the second support rod 222 can adjust its support posture in real time according to the changes in net tension and water flow impact, ensuring that the water part of the interception net 10 remains stretched and flat during the cleaning process, providing an unobstructed working base for the first flushing device 23.

[0058] The adjustable pitch angle design of the first support rod 221 solves the problem that traditional fixed gantry frames cannot adapt to different specifications of intercepting nets 10 or the changes in net posture under complex water flow conditions, thus improving the net deployment rate. Combined with the first flushing device 23, it can achieve a one-time comprehensive cleaning, significantly shortening the cleaning cycle. The mechanized adjustment of the first gantry drive structure 223 replaces manual adjustment, reducing operational errors and labor intensity caused by manual intervention. The design of the second support rod 222, which is parallel to the working surface, enhances the stability of the net support, avoids flushing blind spots caused by net shaking during the cleaning process, significantly improves the cleaning quality, and extends the service life of the intercepting net 10, reducing the frequency of replacement.

[0059] The first support rod 221 can be provided in one or two ways to be respectively connected to the opposite ends of the second support rod 222, or multiple rods can be provided at intervals along the extension direction of the second support rod 222. This application embodiment does not impose specific restrictions on this.

[0060] In one embodiment, the first gantry 22 further includes a third support rod 226 and a fourth support rod 224. The two ends of the fourth support rod 224 are connected to the first support rod 221 and the third support rod 226, respectively, and the fourth support rod 224 is angled to the first support rod 221. The third support rod 226 is parallel to and spaced apart from the second support rod 222. The second support rod 222 and the third support rod 226 together support the above-water portion of the interception net 10. The angle between the fourth support rod 224 and the first support rod 221 can be set as needed, such as 30°, 60°, or 90°. The number and position of the fourth support rods 224 can be set as needed, and this embodiment does not impose specific limitations on this.

[0061] Specifically, in this embodiment of the interception net replacement and cleaning operation platform, the structure of the first gantry 22 is further optimized based on the original first gantry 22. Specifically, the first gantry 22 adds a fourth support rod 224 fixedly connected to the first support rod 221, and a third support rod 226 connected to the end of the fourth support rod 224 away from the first support rod 221. The third support rod 226 and the second support rod 222 are arranged in a parallel spatial layout with intervals and staggered positions. The first support rod 221 is still rotatably connected to the working platform 1 through a shaft connection. The two ends of the first gantry drive structure 223 are respectively connected to the working platform 1 and the first support rod 221 to provide rotational driving force. The second support rod 222 and the third support rod 226 are both parallel to the working surface of the working platform 1. Together, they constitute the support structure of the water part of the interception net 10. The interval arrangement forms a stable support interval to adapt to interception nets 10 with different width specifications.

[0062] Based on this, when the traction device 21 pulls the interception net 10 to be cleaned to the water operation area, the first gantry drive structure 223 drives the first support rod 221 to rotate around the connecting shaft with the working platform 1 according to the deployment requirements of the interception net 10. This drives the second support rod 222 connected to it and the third support rod 226 indirectly connected to it to adjust their positions synchronously. This allows the two parallel and spaced support rods to accurately fit the water part of the interception net 10 and provide synchronous support from different lateral positions of the net. This effectively reduces the risk of the interception net 10 sagging, wrinkling, or shifting due to its own flexibility, water flow impact, or cleaning impact force. It ensures that the water part of the interception net 10 remains fully extended and flat throughout the cleaning process, providing an unobstructed and blind-spot-free cleaning operation base for the first flushing device 23 (located on the first gantry 22). At the same time, during the cleaning process, the spaced support structure of the double support rods can balance the flushing reaction force on the net, further maintaining the stability of the net's posture.

[0063] By adopting the above technical solution, compared with the support method of a single second support rod 222, the dual-point collaborative support structure formed by the parallel and spaced second support rods 222 and the third support rod 226 significantly improves the support stability and adaptability of the water-based part of the interception net 10. It can effectively suppress the swaying amplitude of the net during the cleaning process, improve the flatness of the net unfolding to a higher level, and effectively reduce the risk of rinsing blind spots caused by local sagging of the net due to a single support. This allows the first rinsing device 23 to complete the full coverage and no dead angle rinsing of the water-based part of the net in one go, further shortening the single cleaning time and improving cleaning efficiency. At the same time, the spaced support of the dual support rods can evenly distribute the tension and rinsing impact force on the net to the two support points, avoiding problems such as local wear and tear of the net caused by concentrated force at a single support point, extending the service life of the interception net 10, and indirectly reducing the frequency of net replacement.

[0064] Specifically, in one embodiment, the second support rod 222 is connected to the end of the first support rod 221 away from the work platform 1, and the fourth support rod 224 is connected to the middle of the first support rod 221, so as to ensure that the third support rod 226 and the second support rod 222 maintain a parallel spatial arrangement with intervals and misalignment.

[0065] In one embodiment, the first flushing device 23 includes a first cleaning pipe 231 connected to a high-pressure water supply system. The first cleaning pipe 231 is connected to a first support rod 221 and is arranged parallel to and spaced apart from a second support rod 222. A plurality of first flushing nozzles 232 are spaced apart along the length of the first cleaning pipe 231. The first flushing nozzles 232 are used to flush the interceptor net 10 from above downwards. It is understood that the length direction of the first cleaning pipe 231 is parallel to the second support rod 222.

[0066] Preferably, the interceptor net replacement and cleaning operation platform includes a high-pressure water supply system, which is located on the operation platform 1. In this way, the interceptor net replacement and cleaning operation platform has more integrated functions and can meet the needs of being used independently for operation.

[0067] Specifically, the first flushing device 23 of the interception net replacement and cleaning operation platform has a structure with the first cleaning pipe 231 as the core execution component. The first cleaning pipe 231 and the second support rod 222 are set at intervals (the interval distance is adapted to the thickness of the interception net 10 and the flushing pressure requirements), and the length direction of the first cleaning pipe 231 matches the length direction of the second support rod 222. Multiple first flushing nozzles 232 are arranged sequentially along the length direction of the first cleaning pipe 231. The spray direction of each first flushing nozzle 232 is set to point from the top of the interception net 10 downwards. At the same time, the first cleaning pipe 231 is connected to the high-pressure water supply system on the operation platform 1 through a pipeline to form a complete flushing fluid passage. The first flushing device 23 is indirectly assembled with the operation platform 1 by relying on the second support rod 222 of the first gantry 22 to ensure that the position corresponds precisely to the water support area of ​​the interception net 10.

[0068] Specifically, the first cleaning pipe 231 is indirectly connected to the first support rod 221 via the sixth support rod 227. The sixth support rod 227 and the first support rod 221 are set at an angle, which can be set as needed to 30°, 60°, 90°, etc. Preferably, the first cleaning pipe 231 and the first support rod 221 are respectively connected to opposite ends of the sixth support rod 227. This helps to ensure that the first cleaning pipe 231, the first flushing nozzle 232, and the second support rod 222 are kept at a distance (the distance is adapted to the thickness of the interception net 10 and the flushing pressure requirements).

[0069] Based on this, when the traction device 21 pulls the interception net 10 to the second support rod 222, and the second support rod 222 opens up the water surface part of the interception net 10 and keeps it flat, the first cleaning pipe 231 is positioned at a preset rinsing position above the interception net 10 because it is spaced apart from the second support rod 222. At this time, the high-pressure water supply system delivers high-pressure water to the first cleaning pipe 231. The water flows through multiple first rinsing nozzles 232 arranged sequentially along the length of the pipe and is sprayed synchronously downwards onto the surface of the water surface part of the interception net 10. Since the multiple first rinsing nozzles 232 are spaced apart along the length of the pipe, their spray range can completely cover the transverse area of ​​the water surface part of the interception net 10 supported by the second support rod 222. Moreover, the downward spray direction allows the rinsing force to directly act on the marine organisms, mud, and other debris attached to the surface of the net. At the same time, gravity helps the debris to detach from the net and fall with the water flow, avoiding debris residue.

[0070] By adopting the above technical solution, firstly, the continuous arrangement of multiple first flushing nozzles 232 along the length of the first cleaning pipe 231 achieves full lateral coverage flushing of the above-water portion of the interception net 10, effectively solving the problem of local blind spots in traditional manual flushing or single-nozzle flushing. It eliminates the need for segmental adjustments to the flushing position, and, combined with the flat net surface supported by the second support rod 222, a single flush can complete the comprehensive cleaning of the above-water portion of the net, significantly improving cleaning efficiency. Secondly, the downward-facing spray angle design of the first flushing nozzles 232 allows the flushing force and gravity to work synergistically, enhancing the removal effect on stubborn attachments (such as hardened marine organisms). Compared to horizontal or upward flushing, the debris removal rate is significantly improved. The first cleaning pipe body 231 and the second support rod body 222 are spaced apart, which not only avoids interference between the flushing device and the support structure, but also ensures that the flushing nozzle and the surface of the net are kept at the optimal flushing distance (avoiding damage to the net if the distance is too close or reduction of flushing force if the distance is too far). This balances the cleaning effect and the service life of the interception net 10. At the same time, the mechanized high-pressure flushing replaces manual hand flushing operation, further reducing the labor intensity of the operators. Moreover, the flushing process does not require manual intervention, which is in line with the automation and safety design goals of the overall operation platform. This indirectly reduces the problem of incomplete cleaning caused by improper manual operation and helps to reduce the replacement frequency of the interception net 10.

[0071] In one embodiment, the first gantry 22 further includes a rotating rod 225 rotatably connected to the end of the fourth support rod 224 away from the first support rod 221, and the rotating rod 225 is capable of rotating about a rotation axis parallel to the length direction of the third support rod 226.

[0072] The first flushing device 23 includes a second flushing pipe 233 and a third flushing pipe 234, both connected to a high-pressure water supply system. The second flushing pipe 233 is connected to the end of the fourth support rod 224 away from the first support rod 221 and located beside the third support rod 226. The third flushing pipe 234 is connected to the end of the rotating rod 225 away from the fourth support rod 224. The second flushing pipe 233, the third flushing pipe 234, and the third support rod 226 are arranged parallel to each other and spaced apart. The second flushing pipe 233 has a plurality of second flushing nozzles 235 spaced along its length. The second flushing nozzles 235 are used to flush the intercepting net 10 from below upwards. The third flushing pipe 234 has a plurality of third flushing nozzles 236 spaced along its length. The third flushing nozzles 236 are used to flush the intercepting net 10 from above downwards. The rotating rod 225 can rotate around the axis manually or electrically to drive the third cleaning tube 234 to rotate around the axis, thereby adjusting the cleaning angle of the third cleaning tube 234.

[0073] Specifically, the first gantry 22 of the replacement cleaning operation platform of the interception net has been further optimized in terms of structural composition. In addition to the existing first support rod 221, third support rod 226, fourth support rod 224, and first gantry drive structure 223, a new rotating rod 225 has been added. The rotating rod 225 is rotatably assembled with the fourth support rod 224 through a shaft connection or other means, and the axis of rotation of the rotating rod 225 is parallel to the length direction of the third support rod 226. At the same time, the second cleaning pipe 233 in the first flushing device 23 is connected to... The fourth support rod 224 is fixedly connected (maintaining a fixed downward rinsing posture), while the third cleaning tube 234 is fixedly connected to the rotating rod 225. The rotating rod 225 is equipped with a manual adjustment knob (such as a worm gear adjustment mechanism) or an electric drive component (such as a servo motor), which can rotate around the axis through manual operation or automatic control, thereby driving the third cleaning tube 234 to rotate around the axis synchronously, so that the rinsing angle of the third cleaning tube 234 (the angle between it and the surface of the interceptor net 10) can be flexibly adjusted within a preset range (such as 30°-90°).

[0074] By adopting the above technical solution, when the interception net 10 is pulled to the third support rod 226 and opened by it, the third support rod 226 (in conjunction with the second support rod 222) opens the above-water portion of the interception net 10 and keeps it in a flat state. At the same time, the second cleaning pipe 233 and the third cleaning pipe 234 synchronously receive the high-pressure water flow delivered by the high-pressure water supply system. The second flushing nozzle 235 installed on the second cleaning pipe 233 sprays water upwards, stably flushing the lower surface of the interception net 10 from below. The water jets upwards against the mud, sand, marine organisms, and other debris attached to the lower surface. The third flushing nozzle 236 on the third cleaning pipe 234 sprays water downwards, creating a downward impact on the deposits on the upper surface of the intercepting net 10. The bidirectional water flow creates a counter-current effect inside the net, which can directly peel off the deposits on both sides of the net and also wash away the fine impurities in the pores of the net through the water flow. At the same time, the peeled debris is removed from the net by the bidirectional water flow, preventing secondary accumulation on the surface of the net.

[0075] If it is necessary to adjust the rinsing effect according to the state of attachments in different areas of the upper surface of the interception net 10 (such as stubborn marine organisms at the edges and fine silt in the middle), the adjustment knob can be turned manually or the electric drive component can be started to make the rotating rod 225 rotate around the connecting shaft with the fourth support rod 224, thereby driving the third rinsing nozzle 236 on the third cleaning pipe 234 to change the spray angle. For areas with stubborn attachments, the angle of the third cleaning pipe 234 can be adjusted to a smaller angle with the surface of the net (such as 30°-45°) to enhance the peeling effect by using the tangential impact force of the high-pressure water flow. For flat areas of the net or small impurities, the angle can be adjusted to a larger angle (such as 60°-90°) to achieve large-area coverage rinsing. If there are slight wrinkles in the net, the angle of the third cleaning pipe 234 can also be adjusted to make the water flow accurately rinse the blind spots in the wrinkles, ensuring that no area is missed during rinsing.

[0076] Thus, firstly, the bidirectional flushing structure effectively solves the problem that traditional single-direction flushing is difficult to cover both sides and pores of the net body, improving the cleaning coverage of the above-water part of the interceptor net 10. In particular, for stubborn impurities such as fine mud and attached algae in the pores of the net body, the penetrating flushing effect of bidirectional water flow is significantly improved compared with single-direction flushing, the impurity removal rate is increased, and the cleaning quality is greatly improved. At the same time, the bidirectional flushing water flow design reduces the impact stress on the net body caused by single-direction flushing, effectively reducing the risk of fiber stretching and deformation or mesh enlargement caused by long-term action of single-direction high-pressure water flow, effectively protecting the structural integrity of the interceptor net 10, extending the service life of the net body, and indirectly reducing the frequency of net replacement.

[0077] Secondly, the nozzles evenly arranged along the length of the pipe ensure that the water flow is evenly distributed on the surface of the net, with no blind spots. Combined with the flat net surface supported by the third support rod 226, a complete cleaning can be completed without adjusting the rinsing position, further shortening the cleaning time and improving work efficiency. At the same time, this mechanized bidirectional rinsing structure completely replaces the manual operation of turning the net over for cleaning, avoiding the safety risks and labor intensity caused by manual intervention. It perfectly matches the automated operation requirements of the work platform and ensures the safety and efficiency of the overall operation process.

[0078] Thirdly, the adjustable angle design of the third cleaning pipe 234 solves the problem that traditional fixed-angle flushing devices cannot adapt to different types of deposits and local conditions of the net, making the flushing method more targeted and improving the removal rate of stubborn deposits. It also avoids the problems of over-flushing (damaging the net) or under-flushing (leaving impurities) in some areas due to fixed-angle flushing, balancing cleaning effectiveness and net protection. Furthermore, the configuration of both manual and electric adjustment modes meets the need for quick manual adjustment in emergency situations and adapts to the overall automated operation process of the work platform. When linked with the platform control system, it can automatically adjust the flushing angle based on the degree of net contamination detected by sensors, further reducing manual intervention and labor intensity. In addition, angle adjustment is achieved only by rotating the rod 225 and the drive assembly, resulting in a simple structure and low maintenance costs. While improving cleaning flexibility, it does not significantly increase equipment complexity, ensuring the economy and reliability of the work platform.

[0079] Fourthly, the fourth support rod 224 not only provides a stable assembly base for the rotating rod 225 and the second cleaning pipe 233, but also strengthens the overall structural rigidity of the first gantry 22, effectively reducing the risk of gantry deformation caused by water flow reaction force during the rinsing process, and improving the operational stability and service life of the equipment.

[0080] In one embodiment, the second gantry 31 includes: a telescopic support rod 312, one end of which is rotatably connected to the work platform 1, and the length of the telescopic support rod 312 is adjustable;

[0081] The fifth support rod 313 is connected to the end of the telescopic support rod 312 away from the working platform 1. The fifth support rod 313 is used to support the underwater part of the interception net 10.

[0082] The second gantry drive structure 314 is connected to the telescopic support rod 312 and is used to drive the telescopic support rod 312 to rotate relative to the working platform 1, so that the pitch angle of the telescopic support rod 312 is adjustable, thereby driving the fifth support rod 313 to move closer to or further away from the working platform 1.

[0083] Specifically, the second gantry 31 of the interception net replacement and cleaning operation platform has a core support component of telescopic support rod 312. One end of the telescopic support rod 312 is axially connected to the working platform 1, and the other end is fixedly connected to the fifth support rod 313. At the same time, a second gantry drive structure 314 (which can be a hydraulic cylinder, electric push rod, or gear transmission assembly) is configured to drive the telescopic support rod 312 to rotate. The telescopic support rod 312 adopts a multi-section nested structure (such as inner and outer tubes with a locking mechanism). The length extension and retraction are achieved through hydraulic drive or mechanical adjustment, thereby driving the fifth support rod 313 connected to it to move closer to or away from the working platform 1. The length direction of the fifth support rod 313 is consistent with the unfolding direction of the underwater part of the interception net 10. The surface of the fifth support rod 313 can be provided with anti-slip protrusions or a flexible buffer layer to enhance the fit with the net. The overall structure forms an underwater support system with adjustable pitch angle and support length.

[0084] Based on this, when the traction device 21 pulls the underwater part of the interception net 10 to the work area, the second gantry drive structure 314 first causes the telescopic support rod 312 to rotate relative to the working platform 1, adjusting the pitch angle of the fifth support rod 313 to adapt to the underwater water flow direction and the net's traction posture, ensuring that the fifth support rod 313 can accurately contact the interception net 10; then, according to the width specifications of the interception net 10, the fifth support rod 313 is pushed or pulled closer to or further away from the working platform 1 by the length adjustment function of the telescopic support rod 312, until the fifth support rod 313 fully expands the underwater part of the interception net 10, keeping the net in a flat and relaxed state; during the cleaning process, the pitch angle can be finely adjusted in real time by the second gantry drive structure 314 according to the changes in the net's posture caused by the water flow impact, and the support length can be finely adjusted by the telescopic support rod 312 to maintain the stability of the net and provide a continuous and stable rinsing base for the second flushing device 32.

[0085] In one embodiment, the second flushing device 32 includes a fourth cleaning pipe 321 connected to a high-pressure water supply system. The fourth cleaning pipe 321 is connected to the end of the telescopic support rod 312 away from the working platform 1 and is arranged parallel to and spaced apart from the fifth support rod 313. The fourth cleaning pipe 321 is provided with a plurality of fourth flushing nozzles 322 spaced apart along its length. The fourth flushing nozzles 322 are used to flush the intercepting net 10 from below upwards.

[0086] Specifically, the second flushing device 32 of the interception net replacement and cleaning operation platform has a core actuating component: a fourth cleaning pipe 321. It is spaced apart from the fifth support rod 313 in the second gantry 31, which supports the underwater portion of the interception net 10 (the spacing matches the thickness of the underwater portion of the interception net 10 and the high-pressure flushing requirements, avoiding interference between the pipe and the net or support rod during flushing). The length direction of the fourth cleaning pipe 321 is aligned with the length direction of the fifth support rod 313 to accommodate the lateral range of the underwater portion of the interception net 10 extended by the fifth support rod 313. Along the length of the fourth cleaning pipe 321 itself... Multiple fourth flushing nozzles 322 are evenly arranged in sequence. The spray direction of each fourth flushing nozzle 322 is set to point upwards from below the interception net 10 towards the net body. At the same time, the fourth cleaning pipe 321 is connected to the high-pressure water supply system on the working platform 1 through a corrosion-resistant high-pressure pipeline, forming a complete underwater high-pressure flushing fluid passage. The fourth cleaning pipe 321 is indirectly fixed to the telescopic support rod 312 or the fifth support rod 313 of the second gantry 31 through a bracket structure, ensuring that its position always accurately corresponds to the underwater area of ​​the interception net 10 supported by the fifth support rod 313, and its position is adjusted synchronously with the extension or pitch of the fifth support rod 313.

[0087] Based on this: when the second gantry 31 adjusts the length of the telescopic support rod 312 and the pitch angle of the second gantry drive structure 314, causing the fifth support rod 313 to open the underwater part of the interception net 10 and maintain a flat and stable state, the high-pressure water supply system delivers a high-pressure water flow with a preset pressure to the fourth cleaning pipe 321. The water flow passes through multiple fourth flushing nozzles 322 evenly distributed along the length of the pipe, and is synchronously sprayed from bottom to top onto the lower surface of the underwater part of the interception net 10; at this time, the high-pressure water flow... The upward impact force directly peels off marine organisms (such as shellfish and algae), silt, and fine impurities in the pores attached to the lower surface of the net. At the same time, the peeled impurities are removed from the net by the combined action of the water flow thrust and their own weight, and drift away from the working area with the underwater water flow, avoiding secondary accumulation of impurities on the surface or in the pores of the net. Furthermore, since the fourth flushing nozzle 322 is evenly arranged along the entire length of the pipe, its spray range can completely cover the underwater part of the interception net 10 supported by the fifth support rod 313, achieving thorough flushing.

[0088] In one embodiment, the second flushing device 32 further includes a photographic structure mounted on the fifth support rod 313, which is used to acquire images of the underwater portion of the interception net 10. Therefore, by mounting a photographic structure on the fifth support rod 313 to acquire images of the underwater portion of the interception net 10 in real time, it is convenient to promptly check the cleaning status of the underwater portion of the interception net 10.

[0089] like Figure 6As shown, in one embodiment, pulleys 20 are coaxially arranged on the second support rod 222, the third support rod 226, and the fifth support rod 313. The pulleys 20 can rotate around their own axes, so that the intercepting net 10 experiences rolling friction when moving on the second support rod 222, the third support rod 226, and the fifth support rod 313, thereby reducing the resistance experienced by the intercepting net 10, improving the traction efficiency of the intercepting net 10, and reducing the possibility of damaging the intercepting net 10.

[0090] In one embodiment, guide plates 30 are provided on the second support rod 222, the third support rod 226 and the fifth support rod 313.

[0091] Specifically, the guide plates 30 on the second support rod 222 and the third support rod 226 above water are made of weather-resistant metal or high-strength engineering plastic. The guide plates 30 on the fifth support rod 313 underwater have additional corrosion-resistant properties. All guide plates 30 are convex or inclined (the convex surface faces the traction direction of the interception net 10, and the inclination angle matches the traction path of the net). They are connected to the corresponding support rod by bolt fixing or sealing welding (underwater) and are arranged at intervals along the length of each support rod (the spacing is adapted to the mesh size of the interception net 10 to avoid jamming the net wires). The edges of the guide plates 30 are all provided with rounded corner transition structures to prevent scratching the net.

[0092] Based on this, when the traction device 21 pulls the interception net 10, the underwater part first contacts the guide plate 30 of the fifth support rod 313. The arc-shaped convex surface guides the net to slide smoothly along the preset path to the support surface of the fifth support rod 313, avoiding the net from getting stuck or tangled with the ends or corners of the rod. As the traction advances, the above-water part of the net contacts the guide plates 30 of the second and third support rods 226. The guide plates 30 further guide the net to unfold and precisely fit the support surface of the support rod, assisting the support rod to open the net to a flat state. During the cleaning process, the guide plates 30 can prevent the net from shifting laterally due to the impact of water flow or the reaction force of rinsing, maintaining the relative position stability between the net and the rinsing device (first and second rinsing devices 32). At the same time, the arc-shaped / inclined structure guides the debris being rinsed (the debris above water slides along the guide plate 30 to the water surface, and the underwater debris drifts away along the convex surface with the water flow), preventing it from accumulating between the support rod and the net.

[0093] In one embodiment, the first gantry 22 defines a first flushing zone and a second flushing zone located below the first flushing zone. The first flushing zone corresponds to a first flushing device 23, and the second flushing zone corresponds to a second flushing device 32. The flushing water pressure of the first flushing zone and the second flushing zone is 16 MPa to 25 MPa, and the flow rate is 350 liters / minute to 700 liters / minute.

[0094] In one embodiment, the cleaning pipes of the first cleaning pipe 231, the second cleaning pipe 233, the third cleaning pipe 234 and the fourth cleaning pipe 321 are all divided into two water outlet side areas and a water outlet middle area located between the two water outlet side areas. The water outlet side areas and the water outlet middle area are controlled to flow water independently by remote control valves.

[0095] like Figure 7 As shown, in one embodiment, the working platform 1 includes a first plate 11 and a second plate 12 connected to the first plate 11, and the first plate 11 and the second plate 12 are detachably connected.

[0096] Specifically, the working platform 1 of the interception net replacement and cleaning operation platform adopts a split design in terms of structure, specifically including two core modules: a first piece 11 and a second piece 12. The joint between the first piece 11 and the second piece 12 is equipped with a suitable detachable connection structure (such as a flange connection assembly, a high-strength bolt group with a positioning pin, or a quick-locking buckle structure), and a sealing strip (for waterproofing requirements in water operations) or a buffer gasket (to reduce structural collision damage during assembly) is added to the joint surface to ensure the sealing and stability of the overall structure after assembly; Meanwhile, the first piece 11... The first piece 11 and the second piece 12 are modularly partitioned according to the operational function requirements. For example, the first piece 11 can be pre-set with the installation interface and load-bearing structure for the traction device 21, the first gantry 22 and other components of the water cleaning mechanism 2. The second piece 12 is pre-set with the installation interface and waterproof structure for the second gantry 31, the high-pressure water supply system auxiliary components and other components of the underwater cleaning mechanism 3. The size and weight of the two pieces are adapted to the load-bearing and transportation restrictions of conventional transportation tools (such as trucks and ships). Moreover, the volume of a single piece after being split is convenient for passing through narrow passages or hoisting spaces around the water intake of a nuclear power plant.

[0097] In one embodiment, the working platform 1 is provided with guide rollers 13, and there is a gap between the guide rollers 13 and the surface of the working platform 1 for the interception net 10 to pass through.

[0098] Specifically, since the interception net 10 requires a large traction force, a guide roller 13 is specially set on the working platform 1. The guide roller 13 is arranged horizontally so that the interception net 10 can pass under the guide roller 13 and spread out on the working platform 1 after passing over the gantry.

[0099] The work platform 1 is equipped with a grating, and the interception net 10 rests on the grating, keeping the interception net 10 suspended on the work platform 1. This allows workers to use handheld high-pressure water guns to precisely rinse away any remaining marine organisms on the interception net 10, ensuring that all remaining marine organisms are thoroughly cleaned. The handheld high-pressure washer reaches a pressure of 250 kg as the third stage of rinsing.

[0100] In one embodiment, the working platform 1 is provided with two traction devices 21. The two traction devices 21 are symmetrically arranged based on the center line of the interception net 10. The two traction devices 21 apply a traction force in a figure-eight direction to the interception net 10, thereby being able to pull the interception net 10 with an outward traction force, which helps to deploy the interception net 10.

[0101] Specifically, in order to ensure that the interception net 10 can be fully deployed during the rinsing process, two traction devices 21 (e.g., winches) are used to pull outwards at an angle with a figure-eight traction force. This arrangement helps the interception net 10 to be deployed more easily when passing through the guide rollers 13.

[0102] In one embodiment, the working platform 1 is provided with an inclined deck 14, which is inclined toward the water surface and is used to support the interception net 10.

[0103] Specifically, the working platform 1 is designed with an inclined deck 14 with a folded slope, which facilitates the rapid discharge of high-pressure flushing water and prevents water accumulation from affecting the flushing effect. It also makes it easier for the interception net 10 to approach the water surface during loading and unloading, improving operational convenience.

[0104] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
