[0030] As shown in Figures 1 to 6 A water conservancy project water inlet trash rack device with self-cleaning function, characterized in that it comprises a trash rack 1, a trash collecting cage 2 and a cleaning device 3. The trash rack 1 is fixedly arranged at the water inlet flow channel of the water conservancy facility, and a plurality of horizontally arranged bars 11 are fixedly arranged on the trash rack 1, the bars 11 are uniformly distributed in the vertical direction, and a strip-shaped water passing hole 12 is formed between adjacent two bars 11; the trash collecting cage 2 is located on one side of the trash rack 1, and the trash collecting cage 2 and the trash rack 1 jointly intercept sundries in the water inlet flow channel, and a trash collecting opening 21 is formed on one side of the trash collecting cage 2; the cleaning device 3 is located at the front end of the trash rack 1, and the cleaning device 3 comprises a supporting track 31, a cleaning scraper 32 and a driving motor 33, the supporting track 31 is arranged between the water inlet flow channels, and the extension direction of the supporting track 31 is consistent with the extension direction of the bars 11, the cleaning scraper 32 abuts against the bars 11, and the end portion of the cleaning scraper 32 protrudes a cleaning tooth 321 which penetrates into the strip-shaped water passing hole 12, the cleaning scraper 32 is slidingly connected to the supporting track 31, and the driving motor 33 is installed to the supporting track 31, and the driving motor 33 can drive the scraper to move along the extension direction of the supporting track 31, so as to realize automatic cleaning of the surface of the trash rack 1.

[0031] In an embodiment, the design of the trash screen 1 allows water to flow through the strip-shaped water holes 12 while intercepting larger debris. The design of the debris collection cage 2 further collects the debris intercepted by the trash screen 1 and concentrates the collection and processing through the debris collection port 21. The design of the cleaning device 3 moves the cleaning scraper 32 along the support rail 31 by driving the motor 33, and the cleaning teeth 321 on the cleaning scraper 32 effectively remove the debris attached to the screen bars 11, thereby maintaining the water passing capacity of the trash screen 1.

[0032] In an embodiment, the driving motor 33 periodically drives the cleaning scraper 32 to reciprocate along the support rail 31, so that the debris attached to the surface of the trash screen 1 is pushed into the debris collection cage 2, achieving the cleaning and collection of debris in front of the trash screen 1. This technical solution integrates the trash screen 1, the debris collection cage 2 and the cleaning device 3, realizes the self-cleaning function of the trash screen 1 at the water inlet, and solves the problem of reduced water passing capacity caused by debris attachment in traditional trash screens 1. Compared with the prior art, the device reduces the frequency and difficulty of manual cleaning, improves the operation efficiency and reliability of water conservancy facilities. Through the automatic cleaning process, the device can continuously operate without stopping, thereby reducing the impact on the normal scheduling of water conservancy projects and the utilization of water resources.

[0033] Preferably, the support rail 31 is provided with a running groove 311, and the bottom of the driving motor 33 is provided with a driving wheel 331 installed in the running groove 311. The driving motor 33 can reciprocate along the running groove 311 through the driving wheel 331, so that the driving motor 33 drives the cleaning scraper 32 to move along the extension direction of the running groove 311.

[0034] Specifically, the running groove 311 is a groove structure formed on the support rail 31, and its extension direction is consistent with that of the support rail 31. The driving wheel 331 is installed at the bottom of the driving motor 33, and the shape and size of the driving wheel 331 are matched with those of the running groove 311, so that the driving wheel 331 can move smoothly in the running groove 311. The driving motor 33 drives the cleaning scraper 32 to reciprocate along the extension direction of the support rail 31 through the movement of the driving wheel 331 in the running groove 311. This design makes the movement of the cleaning scraper 32 more stable and enables accurate control of the position and movement speed of the cleaning scraper 32.

[0035] As a preferred embodiment, the running groove 311 can adopt a straight line type groove, and the driving wheel 331 is a roller structure matched with the running groove 311. The driving motor 33 drives the cleaning scraper 32 to reciprocate linearly along the support rail 31 through the rolling of the driving wheel 331. In addition, the bottom of the running groove 311 can be provided with anti-skid patterns or increased friction to prevent the driving wheel 331 from slipping during movement and ensure the movement of the cleaning scraper 32 more stable.

[0036] Therefore, the technical scheme of the present application sets the traveling groove 311 and the driving wheel 331, so that the driving motor 33 can drive the cleaning scraper 32 to move back and forth along the support rail 31 accurately. This design not only improves the operation stability of the cleaning device 3, but also effectively reduces the vibration and deviation of the cleaning scraper 32 during movement, thereby improving the cleaning effect of the trash screen 1. Compared with the prior art, the technical scheme of the present application solves the problem of vibration and deviation of the cleaning device 3 during movement by optimizing the driving structure, and further improves the self-cleaning efficiency of the trash screen 1.

[0037] Preferably, the cleaning device 3 further comprises a limiting rail 34, which is parallel to the support rail 31, and the cleaning scraper 32 is installed between the limiting rail 34 and the support rail 31, and the limiting rail 34 can limit the moving direction of the cleaning scraper 32.

[0038] In an embodiment, the limiting rail 34 is provided to further ensure the stability of the cleaning scraper 32 during movement, avoiding deviation or shaking during cleaning. The parallel arrangement of the limiting rail 34 and the support rail 31 enables the cleaning scraper 32 to slide smoothly between them, thereby ensuring that the cleaning teeth 321 can accurately penetrate the strip-shaped water hole 12 and effectively remove the debris attached to the grid bars 11. The limiting rail 34 can be fixed on the side wall of the water inlet channel by bolts or welding, to ensure that its relative position with the support rail 31 is fixed and unchanged. In addition, the surface of the limiting rail 34 can be coated with wear-resistant material to prolong its service life.

[0039] By introducing the limiting rail 34, the moving direction of the cleaning scraper 32 is effectively limited, avoiding the problem of poor cleaning effect caused by deviation of the cleaning scraper 32. The use of the limiting rail 34 and the support rail 31 further improves the stability and reliability of the cleaning device 3, ensuring that the cleaning scraper 32 can always be in close contact with the grid bars 11, thereby improving the cleaning efficiency. Compared with the prior art, this technical scheme not only reduces the frequency of manual cleaning, but also avoids the risk of equipment damage caused by unstable cleaning device 3, significantly improving the self-cleaning effect of the trash screen 1.

[0040] Preferably, the support rail 31 is provided with a detector 35 near one side of the trash screen 1, and the detection direction of the detector 35 points to the front end of the trash screen 1. The detector 35 is in data connection with the driving motor 33, realizing rapid cleaning of the intercepted debris.

[0041] In an embodiment, the detector 35 can be an optical sensor or an ultrasonic sensor for detecting whether there is debris accumulation at the front end of the trash screen 1. The detector 35 communicates with the drive motor 33 through a data connection, and when debris accumulation is detected, the drive motor 33 can be started to drive the cleaning blade 32 to move along the support rail 31 for cleaning operation. The installation position of the detector 35 can be adjusted to ensure that it can accurately detect the debris condition at the front end of the trash screen 1. In addition, the detector 35 can be provided in multiple numbers and uniformly distributed along the extension direction of the support rail 31 to improve the comprehensiveness and accuracy of detection.

[0042] Specifically, the working principle of the detector 35 is to judge whether there is debris at the front end of the trash screen 1 by transmitting and receiving signals. For example, the optical sensor judges whether there is an object blocking by transmitting a light beam and receiving reflected light, while the ultrasonic sensor judges the distance and existence of the object by transmitting ultrasonic waves and receiving echoes. The data connection between the detector 35 and the drive motor 33 can be realized by wired or wireless means to ensure real-time transmission and response of signals.

[0043] As a preferred embodiment, the detector 35 can be provided with automatic sensitivity adjustment to adapt to changes in different water quality and debris types. In addition, the detector 35 can also be equipped with an alarm function to issue an alarm signal when debris accumulation exceeds a certain threshold, reminding the operator to handle it.

[0044] The technical solution of the present application realizes automatic detection and cleaning of debris at the front end of the trash screen 1 by installing the detector 35 and connecting it with the drive motor 33. Compared with the prior art, this scheme can effectively reduce the frequency and cost of manual cleaning, and improve the operation efficiency and stability of water conservancy facilities. The use of the detector 35 makes the cleaning operation more intelligent and automated, avoiding the problem of increased water flow resistance and equipment damage caused by debris accumulation.

[0045] Preferably, the detector 35 is provided in multiple numbers and uniformly distributed along the extension direction of the support rail 31 to realize real-time monitoring of intercepted debris.

[0046] Preferably, the plane where the pollution collection port 21 is located is consistent with the plane where the trash screen 1 is located, so as to facilitate the cleaning blade 32 to push the debris into the pollution collection cage 2 and realize the cleaning and collection of intercepted debris.

[0047] Preferably, a plurality of water filtering holes 22 are provided around the pollution collection cage 2.

[0048] In an embodiment, the water filtering holes 22 can be evenly distributed around the trash cage 2 to ensure uniform water flow and prevent local blockage. In addition, the material of the water filtering holes 22 can be selected from corrosion-resistant and high-strength materials such as stainless steel or special alloys to enhance the durability and service life of the trash cage 2.

[0049] Through the above design, the technical scheme of the present application can effectively solve the problem of increased water flow resistance caused by impurity accumulation in the existing technology. Specifically, the water filtering holes 22 around the trash cage 2 not only intercept and collect impurities in the water, but also maintain smooth water flow, reducing the impact on the operation of water conservancy facilities. Compared with the prior art, the technical scheme of the present application has higher filtering efficiency and lower maintenance cost, which can significantly improve the practicality and reliability of the trash cage 1 at the inlet of the water conservancy project.

[0050] Preferably, on both sides of the trash cage 2, the side walls of the trash cage 1 and the side walls of the water inlet channel are provided with insertion slots 13, and the two sides of the trash cage 2 are provided with insertion plates 23 inserted into the insertion slots 13, facilitating the installation or replacement of the trash cage 2.

[0051] In an embodiment, the design of the insertion slot 13 allows the trash cage 2 to be stably connected to the side walls of the trash cage 1 and the water inlet channel through the insertion plate 23. The shape and size of the insertion slot 13 can be adjusted according to actual needs to ensure that the insertion plate 23 can be smoothly inserted and maintained stable. The material of the insertion plate 23 can be selected from corrosion-resistant and high-strength materials such as stainless steel or engineering plastics to enhance its service life and reliability. In addition, the insertion slot 13 and the insertion plate 23 can adopt various forms of cooperation, for example, the insertion slot 13 is provided with a guide groove, and the insertion plate 23 is provided with a protrusion matched with the guide groove, so as to realize precise positioning and fixation during insertion.

[0052] As a preferred embodiment, the connection mode of the insertion slot 13 and the insertion plate 23 can also adopt a detachable design, which facilitates the replacement or maintenance of the trash cage 2 when needed. For example, the insertion slot 13 can be provided with a spring buckle or a bolt fixing device, and the insertion plate 23 is provided with a corresponding buckle slot or bolt hole, so that the installation and disassembly of the trash cage 2 can be realized through simple operation.

[0053] Therefore, the technical scheme of the present application realizes the stable connection of the trash cage 2 with the trash cage 1 and the water inlet channel through the design of the insertion slot 13 and the insertion plate 23, avoiding the displacement or falling of the trash cage 2 due to water flow impact or other external forces during use. At the same time, the detachable design of the insertion slot 13 and the insertion plate 23 further improves the maintenance convenience of the equipment, reducing the maintenance cost and time. Compared with the prior art, this scheme not only improves the overall stability and reliability of the trash cage 1 device, but also simplifies the installation and maintenance process of the trash cage 2, which has high practical value.

[0054] Preferably, the surface of the cleaning blade 32 is coated with a Teflon coating. The non-stick property of Teflon makes it difficult for dirt such as oil stains and water stains to adhere to the surface of the blade, preventing the accumulation of dirt on the blade, thereby more effectively removing dirt from the surface being cleaned, improving the efficiency of a single cleaning. For some dirt with strong viscosity, such as oil stains and gum stains, it can also be easily handled. The low friction coefficient of the Teflon coating can make the cleaning blade 32 generate less friction when in contact with the surface being cleaned, effectively reducing the scratching and wear of the surface of the object being cleaned, achieving surface protection of the trash rack 1 and improving the service life of the trash rack 1.

[0055] Preferably, the trash rack 1 is also provided with a water level detector 35 to detect the water level at the inlet.

[0056] In an embodiment, the combination of the water level detector 35 and the trash rack 1 can effectively solve the problem of abnormal water level caused by the blockage of the trash rack 1 in the prior art. When the water level detector 35 detects an abnormal water level, it can trigger the automatic start of the cleaning device 3 or send an alarm to the operator to clean the trash on the trash rack 1 in time. This design not only improves the automation level of the trash rack 1, but also reduces the frequency of manual intervention, thereby reducing maintenance costs and time costs.

[0057] As a preferred embodiment, the water level detector 35 can be linked with the control system of the cleaning device 3. When the water level detector 35 detects an abnormal water level, the control system can automatically start the driving motor 33 to drive the cleaning blade 32 to move along the support rail 31, thereby cleaning the trash rack 1. In addition, the data of the water level detector 35 can also be integrated with other monitoring systems of the water conservancy facility to realize intelligent management of the entire water conservancy project.

[0058] Thus, the technical scheme of the present application realizes real-time monitoring and automatic cleaning of the water level of the trash rack 1 by introducing the water level detector 35, effectively solving the problem of abnormal water level caused by the blockage of the trash rack 1 in the prior art. Compared with the prior art, this scheme not only improves the automation level of the trash rack 1, but also reduces the frequency of manual cleaning, thereby improving the operation efficiency and reliability of the water conservancy facility.

[0059] When the above-mentioned water conservancy project water inlet trash rack device with self-cleaning function is adopted, the water conservancy project water inlet trash rack device with self-cleaning function provided by the application comprises a trash rack 1, a trash collecting cage 2 and a cleaning device 3, the automatic cleaning function of the cleaning device 3 reduces manual operation and improves safety; real-time monitoring is realized through the detector 35, and precise control is realized through the driving motor 33; the trash collecting cage 2 effectively collects sundries, solves the problems of time and labor consumption, safety hazards, lack of real-time monitoring and automatic control and improper sundry treatment in the prior art, and has the advantages of automatic cleaning, reduced manual operation, improved safety, real-time monitoring, precise control and effective collection of sundries.

[0060] The above merely illustrates the embodiments of the application and is not intended to limit the application. The application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the scope of the claims of the application.
