Description

Technical Field

[0001] This application relates to the field of wall operation technology, and in particular to a wastewater recycling device and a wall operation system for wall operation systems. Background Technology

[0002] With the rapid development of the wind power industry, the number of wind turbine towers, a key supporting structure for wind turbine generators, is increasing daily. These towers are constantly exposed to the natural environment, making their surfaces highly susceptible to the accumulation of salt spray, oil, dust, insect remains, and other pollutants. This dirt not only affects the tower's appearance but also accelerates surface corrosion, shortens its lifespan, and negatively impacts the overall image and maintenance costs of the wind farm. Therefore, regular cleaning of the wind turbine tower surfaces has become an indispensable part of wind farm maintenance.

[0003] Currently, wind turbine tower cleaning primarily employs aerial work platforms or wall-climbing robots equipped with high-pressure water jets or scrubbing mechanisms. In these cleaning operations, the wall-climbing system moves along the wall surface, spraying cleaning fluid (usually water or an aqueous solution of detergent) to impact and wash away dirt, generating large amounts of wastewater mixed with pollutants. If this wastewater is allowed to flow freely, splash, or even be discharged uncontrolled, it will not only pollute the environment but also wet the electrical equipment at the base of the tower, posing significant safety hazards and endangering the safety of on-site workers.

[0004] Existing technologies have attempted to address this issue, such as laying a seepage-proof cloth at the bottom of the tower for simple collection, or using absorbent sponges for adsorption. However, these methods have significant drawbacks: the seepage-proof cloth has low collection efficiency; and methods like sponge adsorption have limited capacity, requiring frequent replacement or cleaning, which cannot meet the needs of continuous, high-flow-rate operations and severely restricts the efficiency of cleaning operations.

[0005] Therefore, how to improve the efficiency of wastewater collection and how to improve the efficiency of wall cleaning systems are urgent technical problems that need to be solved. Utility Model Content

[0006] This application provides a wastewater recycling device for a wall-mounted operation system to solve one or more of the aforementioned technical problems in the prior art.

[0007] According to one aspect of this application, a wastewater recovery device for a wall-mounted work system is disclosed, comprising:

[0008] A flow guiding component is arranged on one side of the working wall surface. The flow guiding component has a flow guiding channel. The side of the flow guiding channel close to the working wall surface is in contact with the working wall surface. The projection of the flow guiding channel on the working wall surface intersects with the direction of sewage flow. The flow guiding channel has an outlet end.

[0009] The support mechanism has one end fixed to the support base surface and the other end connected to the side of the guide channel away from the working wall surface.

[0010] In some embodiments of this application, the support mechanism includes a fixed base, a connecting rod, and a fixing clamp. The fixed base is fixed to the support base surface, the fixing clamp is connected to the side of the guide channel away from the working wall surface, and the connecting rod is located between the fixed base and the fixing clamp, with both ends of the connecting rod connected to the fixed base and the fixing clamp respectively.

[0011] The guide channel is inclined from top to bottom along the direction of sewage flow.

[0012] In some embodiments of this application, the supporting base is a working wall surface, the working wall surface is the wall surface of a wind turbine tower, the fixing seat is a magnetic seat, the magnetic seat is used to adhere to the working wall surface, and the connecting rod and the fixing clamp are connected by a hook (221); and / or,

[0013] The fixing clamp is a clamp-type clamp, a screw clamp, or a spring clamp.

[0014] In some embodiments of this application, the flow guiding component is arranged spirally upward along the axial direction of the wind turbine tower on the outer or inner wall surface of the wind turbine tower.

[0015] In some embodiments of this application, the number of spiral turns of the flow guiding component is at least one.

[0016] In some embodiments of this application, the material of the flow guiding component is a flexible waterproof sheet.

[0017] In some embodiments of this application, the flexible waterproof sheet is a waterproof cloth, the side of the waterproof cloth near the working wall is attached to the working wall, the side of the waterproof cloth away from the working wall is connected to the support mechanism, and a guide groove is formed between the side of the waterproof cloth away from the working wall and the side of the waterproof cloth near the working wall.

[0018] The waterproof fabric is attached to the working wall surface by means of adhesive bonding or magnetic attraction on the side closest to the working wall surface;

[0019] Furthermore, when the waterproof cloth is bonded to the working wall surface by adhesive, the waterproof cloth and the working wall surface are bonded together by waterproof tape, and one part of the waterproof tape is bonded to the working wall surface and the other part is bonded to the waterproof cloth to seal the gap between the waterproof cloth and the working wall surface.

[0020] In some embodiments of this application, the outlet end of the guide channel has a tapering structure, which is used to divert sewage in the guide channel to the outside; and / or,

[0021] The number of the support mechanisms is multiple, and the multiple support mechanisms are spaced apart along the extension direction of the guide channel.

[0022] In some embodiments of this application, the angle between the projection of the guide channel on the working wall and the direction of sewage flow ranges from 20 degrees to 70 degrees.

[0023] According to another aspect of this application, a wall-mounted work system is also disclosed, the wall-mounted work system including a wastewater recovery device for a wall-mounted work system as described in any of the above embodiments.

[0024] The wastewater recovery device for a wall-mounted operation system according to the above embodiments of this application includes a flow guiding component and a support mechanism. The flow guiding component has a flow guiding channel, and the projection of the flow guiding channel on the working wall intersects with the direction of wastewater flow. This structure allows the wastewater flowing along the working wall to be collected by the flow guiding channel, thereby preventing the wastewater from spreading or splashing everywhere. Furthermore, one end of the support mechanism is fixed to a stable support base, and the other end supports the flow guiding channel, forming a stable triangular or cantilever beam support mechanism. This structure ensures that the entire wastewater recovery device remains stable when subjected to water flow impact and its own weight, and will not easily shift or tip over, ensuring the continuity and reliability of the wastewater collection process. At the same time, the design of the support mechanism allows it to adapt to working walls with different curvatures, thereby improving the applicability of the wastewater recovery device.

[0025] The wastewater recovery device for wall-mounted work systems in this application features a modular design, allowing for quick installation and disassembly. It is ideal for temporary wall-mounted work scenarios (such as high-altitude curtain wall cleaning, building exterior wall repair, ship rust removal, wind turbine tower cleaning, etc.), improving work efficiency. Furthermore, the wastewater recovery device in this application promptly recovers wastewater, keeping the working wall and the ground below dry, thus enhancing the safety of high-altitude or edge-prone work.

[0026] Furthermore, the wastewater recovery device for wall-mounted operation systems in this application uses a waterproof fabric as a flow guiding component, and the waterproof fabric is bonded to the working wall surface with waterproof tape. The flexible waterproof fabric can adapt to the curvature changes of the curved surface and adaptively fit uneven areas, eliminating wastewater leakage points caused by the mismatch between the flow guiding component and the curved surface shape. Moreover, the waterproof fabric and the working wall surface are bonded together with waterproof tape, forming a complete and uninterrupted sealing ring between the waterproof tape, the wall surface, and the waterproof fabric. This continuous sealing ring provides good protection against leakage of flowing wastewater, thereby improving wastewater collection efficiency.

[0045] The wastewater recycling device provided in this application can be applied to flat or curved surfaces, and is particularly suitable for walls that are vertical, inclined, or difficult to access. Specifically, it can be applied to the surfaces of equipment such as ship hulls, oil tanks, water tanks, bridges, towers, wind turbine towers and blades, as well as the surfaces of large industrial equipment (such as boilers, reactors, etc.). It is especially adaptable to complex, asymmetric curved surfaces.

[0046] Figure 1 This is a schematic diagram of the structure of a wastewater recycling device for a wall-mounted operation system according to an embodiment of this application, as shown below. Figure 1 As shown, the wastewater recovery device for the wall-mounted operation system includes at least a flow guiding component 100 and a support mechanism 200.

[0047] A flow guiding component 100 is arranged on one side of the working wall surface 300. The flow guiding component 100 has a flow guiding groove 110. The side of the flow guiding groove 110 close to the working wall surface 300 is in contact with the working wall surface 300. The projection of the flow guiding groove 110 on the working wall surface 300 intersects with the direction of sewage flow. The flow guiding groove 110 has an outlet end. One end of the support mechanism 200 is fixed to the support base, and the other end is connected to the side of the flow guiding groove 110 away from the working wall surface 300.

[0048] In this embodiment, the flow guiding component 100 is provided with a flow guiding groove 110, and the side of the flow guiding groove 110 close to the working wall surface 300 is in contact with the working wall surface 300, while the side of the flow guiding groove 110 away from the working wall surface 300 is connected to the support mechanism 200. The flow guiding groove 110 intersects with the sewage flow direction on the working wall surface 300. The flow guiding groove 110 of the sewage recycling device acts as a "gate" or "scraper" on the sewage flow path, directly and forcibly intercepting the flowing sewage and guiding it into the groove, thereby improving the sewage collection efficiency.

[0049] Furthermore, wastewater on the working wall 300 is confined to the diversion channel 110, preventing splashing and improving the working environment. Wastewater within the diversion channel 110 is guided along a predetermined direction through the outlet to a designated collection point or drain, facilitating effective wastewater collection. Additionally, by adjusting the width and depth of the diversion channel 110, different wastewater flow rates can be accommodated, making this wastewater recovery device suitable for various working scenarios.

[0050] For example, the diversion channel 110 is inclined from top to bottom along the direction of sewage flow. In this example, by setting the diversion channel 110 as an inclined structure from top to bottom, the sewage and solid particles carried in the diversion channel 110 will receive an acceleration along the channel direction, significantly increasing the flow velocity and generating a strong scouring force, making it difficult for solids to settle, thereby greatly reducing the possibility of blockage inside the diversion channel 110. Furthermore, the inclined diversion channel 110 has enhanced drainage capacity, which can more quickly drain the intercepted sewage, reducing the risk of sewage overflowing from the channel opening due to insufficient drainage, thereby indirectly improving the reliability and efficiency of collection.

[0051] Furthermore, the angle between the projection of the guide channel 110 onto the working wall surface 300 and the direction of sewage flow ranges from 20 degrees to 70 degrees. In this embodiment, setting the inclination angle of the guide channel 110 relative to the direction of sewage flow between 20 and 70 degrees not only allows the sewage to maintain a good flow velocity and flow pattern but also balances the scouring force and drainage efficiency of the sewage. Optionally, the angle between the projection of the guide channel 110 onto the working wall surface 300 and the direction of sewage flow can be 45 degrees. In this case, the guide channel 110, based on the flow of sewage, can not only effectively utilize gravity to achieve self-cleaning but also experiences lower wear from solid particles in the sewage and has higher sewage collection efficiency.

[0052] In some embodiments of this application, the support mechanism 200 includes a fixed base 210, a connecting rod 220, and a fixing clamp 230. The fixed base 210 is fixed to the support base surface, and the fixing clamp 230 is connected to the side of the guide channel 110 away from the working wall surface 300. The connecting rod 220 is located between the fixed base 210 and the fixing clamp 230, and both ends of the connecting rod 220 are respectively connected to the fixed base 210 and the fixing clamp 230.

[0053] Understandably, the supporting base surface of this application can be the working wall surface 300, the ground, or other supporting surfaces of fixed bases, etc. Correspondingly, the fixed base 210 can be connected to the supporting base surface by means of adhesive, magnetic attraction, screw fixing, etc. The shape of the fixed base 210 is not specifically limited, and it serves to fix to the working base surface so that the guide channel 110 has better stability under the support of the supporting mechanism 200.

[0054] The fixing clip 230 serves as the connection between the support mechanism 200 and the flow guiding component 100. It not only facilitates disassembly and installation but also further ensures the stability of the connection between the support mechanism 200 and the flow guiding component 100, thereby ensuring the sewage collection effect.

[0055] For example, Figure 2 for Figure 1 A partial enlarged view of part A of the wastewater recovery device shown, as follows: Figure 2 As shown, the fixed base 210, connecting rod 220 and fixing clamp 230 of the support mechanism 200 can all be set above the flow guiding component 100. At this time, the fixed base 210 is specifically fixedly connected to the working wall surface 300, the end of the connecting rod 220 close to the working wall surface 300 is fixedly connected to the fixed base 210, the end of the connecting rod 220 away from the working wall surface 300 is connected to the fixing clamp 230, and the fixing clamp 230 is clamped and connected to the side of the flow guiding component 100 away from the working wall surface 300.

[0056] Understandably, the above Figure 2The support mechanism 200 shown above the flow guide component 100 is merely an example; in other embodiments, the support mechanism 200 may also be located below the flow guide component 100. Furthermore, besides consisting of the fixed base 210, connecting rod 220, and fixing clamp 230, the support mechanism 200 may also be composed of other types of components. For example, the support mechanism 200 may include a support frame, specifically a triangular support structure, located below the flow guide component. One end of the support frame is connected to the support base surface, while the other end is connected to the flow guide component 100. That is, the support frame supports the flow guide component 100 on the support base surface. The support frame may also be further provided with fixing parts or clamping parts for maintaining the posture of the flow guide component 100. In some embodiments of this application, the supporting base is the working wall surface 300, the working wall surface 300 is the wall surface of the wind turbine tower, the fixing seat 210 is a magnetic seat, the magnetic seat is used to adhere to the working wall surface 300, and the connecting rod 220 is connected to the fixing clamp 230 by a hook 221.

[0057] In this embodiment, the support base is defined as the working wall surface 300, which can support the flow guiding component 100 without the need for the ground or other mechanisms, thus further improving the ease of installation of the support mechanism 200.

[0058] For example, refer to Figure 7 The end of the connecting rod 220 near the fixing clamp 230 may have a hook 221, and the fixing clamp 230 has a hanging ring. The connecting rod 220 and the fixing clamp 230 can then be connected via the hook and hanging ring. Figure 1 , Figure 3 and Figure 4 As shown, the wind turbine tower wall is a curved surface. One side of the guide channel 110 is in contact with the wind turbine tower wall, while the other side of the guide channel 110 is held by the fixing clamp 230 of the support mechanism 200. In this embodiment, the fixing seat 210 is specifically a magnetic seat. The support mechanism 200 achieves adsorption with the working wall surface 300 through the magnetic seat, enabling rapid and non-damaging connection and separation between the support mechanism 200 and the working wall surface 300, thus allowing for rapid installation and disassembly of the support mechanism 200.

[0059] When the fixed base 210 and the fixed clamp 230 are connected by a hook and ring, and the support mechanism 200 is located above the guide channel 110, in order to further improve the stability of the guide component, the connecting rod 220 of the support mechanism 200 can be further configured such that the cantilever length extending from the fixed base 210 is greater than the width of the guide channel 110. This limitation prevents the side of the waterproof cloth away from the working wall from sagging under the influence of sewage gravity when the guide component is made of waterproof cloth, thereby ensuring the continuity and reliability of the sewage collection process. It is understandable that when the guide component is made of a material with a certain degree of hardness (such as PVC), the guide component itself has a certain strength and will not sag, so the length of the connecting rod 220 can be shortened accordingly.

[0060] In the above embodiment, the connecting rod 220 and the fixing clamp 230 are connected by a non-rigid connection, which can accommodate minor installation errors and allow a certain displacement between the fixing seat 210 and the fixing clamp 230.

[0061] Specifically, the fixing clamp 230 may include a clamp body and an adjusting screw. The clamp body has a U-shaped plate structure and a threaded hole. The screw is located inside the threaded hole, with its two ends located inside the U-shaped groove of the U-shaped plate structure and outside the clamp body, respectively. The object being clamped is located inside the U-shaped groove, specifically between the end of the screw and the side wall of the U-shaped plate structure. The clamping force can be adjusted by rotating the screw. Furthermore, the adjusting screw can also be used to clamp guide components 100 of different thicknesses. Additionally, the end of the screw near the connecting rod 220 has a hook ring, allowing the connecting rod 220 and the fixing clamp 230 to be connected via the hook ring.

[0062] Understandably, the connection between the connecting rod 220 and the fixing clamp 230 via the hook 221 is only one option. In addition, the connecting rod 220 and the fixing clamp 230 can also be connected in other ways, such as bonding or threaded connection. If a threaded connection is used, both the fixing block and the fixing clamp 230 can be provided with threaded holes, and both ends of the connecting rod 220 are provided with external threads that mate with the threaded holes. In this case, the two ends of the connecting rod 220 can be threaded to the fixing block and the fixing clamp 230 respectively.

[0063] Furthermore, the fixing clip 230 can be a clamp clip, a screw clip, or a spring clip. The function of the fixing clip 230 is to hold the flow guiding component 100 so that the flow guiding component 100 remains stable under the support of the support mechanism 200. Therefore, the type of fixing clip 230 is not specifically limited.

[0064] When the working wall 300 is a cylindrical working wall such as a wind turbine tower, the flow guiding component 100 is arranged spirally upward along the axial direction of the wind turbine tower on the outer or inner wall surface of the wind turbine tower. Specifically, when the working wall 300 is the outer wall surface of the wind turbine tower, the flow guiding component 100 is arranged on the outer wall surface of the wind turbine tower, and when the working wall 300 is the inner wall surface of the wind turbine tower, the flow guiding component 100 is arranged on the inner wall surface of the wind turbine tower.

[0065] refer to Figure 3 The guide component 100, located on the outer wall of the wind turbine tower, spirals upwards, and the guide channel 110 on the guide component 100 also spirals upwards. When cleaning the wind turbine tower, the wastewater flowing downwards along the tower wall is collected in the guide channel 110 of the guide component 100, and gradually discharged from the outlet end along the guide channel 110, thus facilitating efficient wastewater collection. In this embodiment, the outlet end can specifically be the lowest point of the guide channel 110, where the wastewater in the guide channel 110 is further discharged from its bottom outlet end into a wastewater tank or other collection device.

[0066] The spiral-shaped guide channel 110 significantly extends the path of sewage from the inflow point of the guide component 100 to the bottom outlet. Due to the inclination of the spiral guide channel 110 itself, the sewage flows smoothly downwards within the channel under gravity, preventing splashing when high-speed water impacts the sewage outlet. Furthermore, the spiral-shaped guide component 100 can be stably fixed to the working wall 300 with relatively few support mechanisms 200, simplifying installation, reducing costs, and providing better overall rigidity and stability.

[0067] Furthermore, the flow guiding component 100 has at least one spiral turn. This single-turn or more spiral structure forms a closed collection ring around the working wall 300, ensuring that any wastewater flowing down the wind turbine tower wall will eventually be intercepted by the spiral flow guiding channel 110, thus achieving 360° all-round collection of wastewater from the wind turbine tower wall without any dead angles.

[0068] In some embodiments of this application, the guide component 100 is made of a flexible waterproof sheet. In this embodiment, the guide component 100 is made of a flexible waterproof sheet with a certain degree of flexibility, which allows the guide component 100 to adapt to wall surfaces with varying diameters from top to bottom. On the curved working wall surface 300, the flexible guide component 100 can fit well with the working wall surface 300, thereby ensuring a better sewage collection effect.

[0069] In some embodiments of this application, the flexible waterproof sheet is a waterproof cloth, the side of the waterproof cloth near the working wall 300 is attached to the working wall 300, the side of the waterproof cloth away from the working wall 300 is connected to the support mechanism 200, and a guide groove 110 is formed between the side of the waterproof cloth away from the working wall 300 and the side near the working wall 300.

[0070] For example, the shape of the waterproof fabric can be rectangular. When the rectangular waterproof fabric is folded into a U-shape, the U-shaped groove of the U-shaped waterproof fabric is the specific flow channel 110. To ensure that the U-shaped groove has good flow guiding effect and stability, then... Figure 6 As shown, one sidewall of the U-shaped waterproof fabric is fully fitted to the working wall surface 300, while the other sidewall of the U-shaped waterproof fabric is fixedly connected to the fixing clip 230 of the support mechanism 200. It is understood that the use of waterproof fabric as the flow guiding component 100 in this embodiment is merely an example; in other embodiments, the flow guiding component 100 may also use other flexible waterproof sheets besides waterproof fabric.

[0071] Furthermore, the side of the waterproof fabric near the working wall surface 300 is adhered to the working wall surface 300 by adhesive or magnetic attraction. When the waterproof fabric is adhered to the working wall surface by adhesive, the waterproof fabric and the working wall surface are bonded together by waterproof tape, with one part of the waterproof tape adhering to the working wall surface and the other part adhering to the waterproof fabric to seal the gap between the waterproof fabric and the working wall surface. For example, the waterproof tape can be a transparent PET tape.

[0072] In the above embodiments, the waterproof cloth is connected to the working wall surface by transparent tape, with one part of the transparent tape adhering to the working wall surface and the other part adhering to the waterproof cloth, so that the transparent tape forms a continuous sealing ring. This not only seals the gap between the waterproof cloth and the working wall surface, but also, when these flexible waterproof tapes are pasted on slightly undulating or slightly rough curved surfaces, the tapes can deform and fill these uneven areas, thereby ensuring the adhesion between the waterproof cloth and working wall surfaces with different curvatures, and thus ensuring the sealing between the waterproof cloth and the uneven curved working wall surfaces, thereby improving the sewage collection efficiency.

[0073] In other embodiments, the waterproof cloth and the working wall surface 300 can also be bonded using adhesive materials other than sealing tape. When the waterproof cloth and the working wall surface 300 are attached by magnetic attraction, the magnet can be sewn or glued to the waterproof cloth first. At the work site, one side of the waterproof cloth is first attracted to the working wall surface 300 by the magnet on the waterproof cloth, and then the magnetic seat of the support mechanism 200 is attracted to the working wall surface 300. The fixing clip 230 of the support mechanism 200 is clamped and fixed to the other side of the waterproof cloth, thereby forming a guide groove 110 between the side of the waterproof cloth that is attached to the working wall surface 300 and the side that is clamped by the fixing clip 230.

[0074] In addition, the sheet-like waterproof material used can be a material that can maintain a specific posture, such as PVC waterproof membrane. Furthermore, when the fixing clamp 230 clamps the side of the flow guide 100 away from the working wall surface 300, in order to prevent the clamped side of the flow guide 100 from sagging, the length of the connecting rod 220 can be set to be greater than or equal to the width of the flow guide groove 110.

[0075] In some embodiments of this application, the outlet end of the guide channel 110 has a constriction structure 111, which is used to guide the sewage in the guide channel 110 to the outside. The constriction structure 111 reduces the cross-sectional area of ​​the outlet end, increases the outlet velocity of the water flow, and prevents the sewage from spreading to both sides due to inertia near the outlet end.

[0076] For example, the shape of the closing structure 111 can be rectangular, trapezoidal, etc., such as... Figure 6 As shown, when the shape of the constriction structure 111 is rectangular, the cross-sectional area of ​​the constriction structure 111 can be half of the cross-sectional area of ​​the guide channel 110.

[0077] In some embodiments, there are multiple support mechanisms 200, which are spaced apart along the extension direction of the guide channel 110. The extension direction of the guide channel 110 may specifically be the direction perpendicular to its cross-section. For example, if the guide channel 110 is a spirally rising guide channel 110, then the extension direction of the guide channel 110 is specifically a spirally rising direction.

[0078] When the flow guiding component 100 is made of a flexible waterproof sheet (such as PVC board) capable of maintaining its posture, the spiral-shaped flow guiding component 100 can ensure stability by relying solely on its own enveloping ability and bonding or magnetic attraction with one side to the working wall surface 300. Therefore, the number of support mechanisms 200 can be reduced accordingly, for example, support mechanisms 200 can be provided only at both ends of the flow guiding component 100. For flow guiding components 100 made of materials such as waterproof fabric, since they cannot maintain their posture on their own, multiple support mechanisms 200 can be used to improve the stability of the flow guiding component 100. (Reference) Figure 3 At this time, there are multiple support mechanisms 200, and there is a gap between two adjacent support mechanisms 200.

[0079] According to another aspect of this application, a wall-mounted work system is also disclosed, the wall-mounted work system including a wastewater recovery device for a wall-mounted work system as described in any of the above embodiments.

[0080] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
