Description

Technical Field

[0001] This utility model relates to the field of aviation and electrical hub technology, and more specifically, to a filter device for preventing debris from clogging the water inlet of an aviation and electrical hub. Background Technology

[0002] As important water conservancy facilities, navigation and hydropower hubs play a crucial role in power generation and navigation, and the smooth operation of their intakes is essential for the stability of the entire hub. However, existing navigation and hydropower hub intakes have many shortcomings in terms of debris handling.

[0003] Currently, most naval aviation and electrical hubs lack effective filtration mechanisms to prevent debris blockage at their inlets. Larger debris such as tree branches, plastic bags, and aquatic plants can easily enter the inlets, causing blockages in the internal equipment. This not only reduces the operational efficiency of the naval aviation and electrical hub but can also lead to equipment malfunctions, increasing maintenance costs and downtime.

[0004] Furthermore, existing devices lack specific functions to handle intercepted debris. Large amounts of debris accumulate near the water inlet, making them difficult to process and transport, not only taking up space but also further impacting water intake efficiency. Prolonged accumulation of debris can also lead to water quality deterioration and negatively affect the surrounding ecosystem.

[0005] In contrast, the filtration device for preventing debris blockage at the inlet of an aviation and electrical hub, based on this invention, effectively solves the problems existing in the prior art and ensures the stable operation of the aviation and electrical hub by employing a filter belt with a grid to accurately intercept debris, a debris crushing box for crushing, and an inclined conveying pipe combined with spiral blades for efficient transport. Therefore, we have made improvements and proposed a filtration device for preventing debris blockage at the inlet of an aviation and electrical hub. Utility Model Content

[0006] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: a filtration device for preventing debris blockage at the inlet of an aviation and electrical hub, comprising a main frame, on both sides of the main frame being respectively installed with side rails for the inlet of the aviation and electrical hub, and an anti-debris blockage filter belt is provided between the two side rails, the anti-debris blockage filter belt being inclined at a 45-degree angle, and a drive gear and a driven gear being respectively connected to the two ends of the anti-debris blockage filter belt, wherein a servo motor is connected to one side of the drive gear.

[0007] As a preferred technical solution of this utility model, the water inlet is provided on the inner plate of the side railing of the water inlet of the navigation and power hub.

[0008] As a preferred technical solution of this utility model, mounting plates are fixed on both sides of the anti-debris clogging filter belt, and the servo motor is mounted on the mounting plate. A filter belt grid is provided on the outer surface of the anti-debris clogging filter belt.

[0009] As a preferred technical solution of this utility model, the front end of the main frame is provided with the anti-clogging filter belt, and the rear end is equipped with a debris crushing box, with a debris crushing rotating shaft passing through the inside of the debris crushing box.

[0010] As a preferred technical solution of this utility model, the outer shaft of the debris crushing rotating shaft is inlaid with crushing blades, and the tail end is connected to a rotating motor, which is mounted on the outer plate of the debris crushing box.

[0011] As a preferred technical solution of this utility model, the bottom of the debris crushing box is connected to a debris crushing and conveying funnel, and a debris crushing and conveying pipe is embedded in the inlet of the debris crushing and conveying funnel.

[0012] As a preferred technical solution of this utility model, the debris crushing and conveying pipe is inclined upward at a 45-degree angle, and the inside of the pipe is a debris conveying and rotating shaft, and the outer shaft of the debris conveying and rotating shaft is provided with debris conveying and rotating spiral blades.

[0013] As a preferred technical solution of this utility model, a rotary servo motor is fixed below the debris crushing and conveying pipe, and a transmission belt connects the debris conveying rotary shaft and the rotary servo motor.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention, through the filter belt grid on the outer surface of the filter belt to prevent debris from clogging, can accurately intercept various types of larger impurities in the water. Its 45-degree inclined structure, combined with the circulating filter belt, not only increases the contact area and time between the water flow and the filter belt, but also improves the filtration efficiency.

[0015] This invention provides preliminary filtration of the incoming water, intercepting most of the impurities outside the naval power hub, thus significantly improving the water quality entering the hub. This helps reduce wear and corrosion on the internal equipment of the naval power hub, extending its service life, and also improves the power generation efficiency and operational stability of the naval power hub.

[0016] This utility model device is equipped with a debris crushing box, and the internal debris crushing rotating shaft and crushing blades can crush the intercepted debris. Crushing larger debris into smaller particles facilitates subsequent transportation and processing, reducing the difficulty and cost of debris handling; on the other hand, the reduced volume of crushed debris reduces storage space occupation and makes it easier to carry out environmentally friendly treatment.

[0017] This invention employs a debris crushing and conveying pipe inclined upwards at a 45-degree angle, and utilizes a debris conveying rotating shaft and debris conveying rotating spiral blades to smoothly convey the crushed debris to a designated location. This conveying method is highly efficient and stable, preventing the accumulation of debris within the device and ensuring its continuous and normal operation.

[0018] The main frame, the side panel of the naval power hub inlet, the filter belt, and the debris shredder are all tightly and rationally connected, resulting in a stable overall structure. The inclined filter belt and conveying pipe structure conform to the movement patterns of debris and facilitates installation and layout, enhancing the device's adaptability and reliability in complex environments. All components, such as the servo motor, rotary motor, and shredder blades, are easily accessible, facilitating routine inspection, maintenance, and replacement. The mounting plates on both sides of the filter belt facilitate the installation and maintenance of the servo motor; the rotary motor mounted on the outer plate of the debris shredder also facilitates motor inspection and maintenance, reducing maintenance costs and difficulty.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1: A filtration device for preventing debris blockage at the inlet of an aviation and electrical hub includes a main frame 1. Side railings 2 for the inlet of the aviation and electrical hub are installed on both sides of the main frame 1. A filter belt 3 for preventing debris blockage is provided between the two side railings 2. The filter belt 3 is inclined at a 45-degree angle. A drive gear 4 and a driven gear 5 are connected to the two ends of the filter belt 3, respectively. A servo motor 6 is connected to one side of the drive gear 4.

[0030] The water inlet 7 is provided on the inner plate of the side railing 2 of the navigation and power hub. Mounting plates 8 are fixed to both sides of the anti-clogging filter belt 3, and the servo motor 6 is mounted on the mounting plates 8. A filter belt grid 9 is provided on the outer surface of the anti-clogging filter belt 3. The front end of the main frame 1 is provided with the anti-clogging filter belt 3, and the rear end is equipped with a debris crushing box 10, with a debris crushing rotating shaft 11 passing through its interior.

[0031] Crushing blades 12 are embedded on the outer shaft of the debris crushing rotating shaft 11, and the tail end is connected to a rotary motor 13, which is mounted on the outer plate of the debris crushing box 10. The bottom of the debris crushing box 10 is connected to a debris crushing conveying funnel 14, and a debris crushing conveying pipe 15 is embedded in the opening of the debris crushing conveying funnel 14.

[0032] The debris crushing and conveying pipe 15 is inclined upward at a 45-degree angle, and the debris conveying and rotating shaft 16 runs through the inside of the pipe. The outer shaft of the debris conveying and rotating shaft 16 is equipped with debris conveying and rotating spiral blades 17.

[0033] A rotary servo motor 18 is fixed below the debris crushing and conveying pipe 15, and a transmission belt 19 connects the debris conveying rotary shaft 16 and the rotary servo motor 18.

[0034] Working principle of the anti-clogging filter device at the inlet of the navigation and power hub: Filtration stage: Water flow introduction: When the navigation and power hub is running, water flows into the device from the inlet 7 on the inner plate of the side railing 2 of the navigation and power hub inlet. The inlet acts as the inlet channel for the water flow, guiding the water flow towards the anti-clogging filter belt 3.

[0035] Filter belt operation: Start the servo motor 6, which drives the drive gear 4 to rotate. Since the drive gear 4 and the driven gear 5 are connected through the anti-clogging filter belt 3, the rotation of the drive gear will drive the anti-clogging filter belt 3 to rotate cyclically. The anti-clogging filter belt 3 is set at a 45-degree angle, which facilitates the movement of debris in a specific direction under the action of gravity.

[0036] Debris filtration: When water flows through the anti-debris filter belt 3, the filter belt grid 9 on the outer surface of the filter belt will intercept debris in the water. Larger debris such as branches and plastic bags will be blocked on the surface of the filter belt by the filter belt grid 9, while the water can pass through the filter belt grid smoothly and continue to flow into the avionics hub, thus achieving preliminary filtration of the incoming water and preventing debris from entering the avionics hub and causing blockage.

[0037] Debris handling stage: Debris conveying: As the anti-clogging filter belt 3 circulates, the debris intercepted on the surface of the filter belt is conveyed to the debris shredder 10 at the end of the device. The inclined filter belt structure and the direction of operation ensure that the debris can smoothly enter the debris shredder.

[0038] Debris crushing: Start the rotary motor 13, which drives the debris crushing rotating shaft 11 to rotate. The crushing blades 12 embedded on the outer shaft of the debris crushing rotating shaft rotate at high speed. When debris enters the debris crushing box 10, the crushing blades 12 will cut and crush the debris, breaking larger debris into smaller particles for subsequent conveying and processing.

[0039] The pulverized debris is transported to the designated location: It falls into the pulverized debris conveying funnel 14 connected to the bottom of the debris pulverizing box 10, and then enters the debris pulverizing conveying pipe 15. The rotary servo motor 18 is started, driving the debris conveying rotary shaft 16 to rotate via the transmission belt 19. The debris conveying rotary spiral blades 17, mounted on the outer shaft of the rotary shaft, rotate along with the shaft. Because the debris pulverizing conveying pipe 15 is inclined upwards at a 45-degree angle, the rotating debris conveying rotary spiral blades 17 transport the pulverized debris upwards along the pipe, ultimately delivering the debris to the designated processing location, completing the entire process of preventing debris blockage and processing.

[0040] By using a filter belt to intercept debris, then using a crushing device to crush the debris, and finally using a screw conveyor to transport the crushed debris out, the system effectively prevents the water intake of the navigation and power hub from being blocked by debris, thus ensuring the normal operation of the navigation and power hub.

[0041] Operating process of the anti-clogging filter device at the inlet of the navigation and power hub: Preliminary preparation: Check the secure connections of all components, including the installation of the main frame 1 to the side panel 2 of the navigation and power hub inlet, the connection of the drive gear 4 and driven gear 5 to the anti-clogging filter belt 3, and the connection of the servo motor 6 to the drive gear 4, ensuring there are no loose or detached parts. Check the power cord connections of the servo motor 6, rotary motor 13, and spiral servo motor 18 to ensure they are correct and can start normally. Check the sharpness of the shredding blades 12 and the condition of the spiral blades 17 for damage or deformation.

[0042] Start-up phase: The servo motor 6 is turned on, and the servo motor 6 starts running and drives the drive gear 4 to rotate. Since the drive gear 4 and the driven gear 5 are connected by the anti-clogging filter belt 3, the rotation of the drive gear 4 will drive the anti-clogging filter belt 3 to start circulating. Its inclined structure makes the filter belt rotate continuously in a predetermined direction.

[0043] Turn on the rotary motor 13, which drives the debris crushing rotary shaft 11 to start rotating. The crushing blades 12 embedded on the outer shaft of the debris crushing rotary shaft 11 then rotate at high speed, preparing for subsequent debris crushing. Turn on the spiral servo motor 18, which drives the debris conveying spiral rotating shaft 16 to rotate via the transmission belt 19. The debris conveying spiral rotating blades 17 on the outer shaft of the debris conveying spiral rotating shaft 16 start rotating, preparing for the conveying of debris.

[0044] Operational Phase: Water Intake and Filtration: Water flows into the device from the inlet 7 on the inner plate of the side panel 2 of the navigation and power hub. When the water flows through the anti-clogging filter belt 3, the filter belt grille 9 on the outer surface of the filter belt acts as an interceptor, blocking larger debris such as branches, plastic bottles, and aquatic plants on the surface of the filter belt, while the water passes smoothly through the filter belt grille 9 and continues to flow into the navigation and power hub. As the anti-clogging filter belt 3 continues to operate, the intercepted debris will move towards the rear end of the device along with the filter belt.

[0045] Debris crushing: When debris moves to the end of the device along the anti-clogging filter belt 3, it falls into the debris crushing box 10. The high-speed rotating crushing blades 12 cut and crush the debris entering the debris crushing box 10, breaking larger debris into smaller particles for subsequent conveying and processing.

[0046] Debris conveying: The crushed debris falls from the bottom of the debris crushing box 10 into the debris crushing conveying funnel 14, and then enters the debris crushing conveying pipe 15. Inside the debris crushing conveying pipe 15, the rotating debris conveying spiral blades 17 continuously convey the crushed debris along the pipe which is inclined upward at a 45-degree angle, and finally convey the debris to the designated processing position.

[0047] Monitoring and maintenance phase: During the operation of the device, a dedicated person shall conduct regular inspections of the device, observe the operation of the anti-debris clogging filter belt 3, and check for problems such as debris entanglement or jamming; observe the operating status of the motor and check for overheating, abnormal noise, etc.

[0048] Regularly clean the filter belt grid 9 to remove residual debris, preventing excessive accumulation that could affect filtration efficiency and the normal operation of the filter belt. Regularly check the wear of the shredder blades 12; replace them promptly if severely worn. Check the debris conveying spiral blades 17 for blockages or damage; address any issues immediately. Shutdown Phase: When the avionics hub stops water intake or requires maintenance, first turn off the spiral servo motor 18 to stop the rotation of the debris conveying spiral shaft 16, thus halting the debris conveying process. Turn off the rotary motor 13 to stop the rotation of the debris shredder shaft 11, ending the shredding operation. Turn off the servo motor 6 to stop the filter belt 3 from clogging. Clean any remaining debris from inside the device and perform a comprehensive inspection and maintenance to prepare for the next operation.

[0049] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
