Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and more specifically, to a modular, assembled irrigation channel gate. Background Technology

[0002] In farmland irrigation canal systems, gates are the core facilities for controlling water distribution and regulating water levels. Existing irrigation canal gates typically only have a single function of blocking and controlling water flow. Their structure is mostly an integral fixed gate plate, raised and lowered by manual or electric screw drive. However, the water in irrigation canals often carries floating and suspended waste such as crop residues, weeds, plastic film, and domestic garbage. If these impurities directly enter downstream irrigation branches, they will not only clog end-point irrigation equipment such as sprinklers and drip irrigation tapes, but also degrade irrigation water quality and affect normal crop growth.

[0003] Even those traditional irrigation canal gates that integrate filtration structures are mostly fixed filters or grids. Their filtration position, interception height, and interception angle are not adjustable, limiting them to intercepting waste only at pre-set water levels or fixed depths. However, in actual operation, irrigation canals experience periodic fluctuations in water levels based on the irrigation district's water demand. During the flood season, large amounts of floating debris accumulate on the surface, while during the dry season or canal maintenance periods, sediment is exposed on the canal bed. Fixed filtration structures cannot adaptively adjust to changes in water level and the shifting of waste distribution areas, resulting in widespread filtration blind spots, frequent blockages, and the need for frequent manual cleaning, severely impacting the normal operating efficiency of the irrigation system.

[0004] Furthermore, the filtration and water control functions of existing irrigation canal gates are often independent, lacking coordinated design. When filtration is required, additional filtration devices must be activated or installed, making the operation cumbersome; when only water control is needed, the filtration components cannot quickly switch to a non-operating state, instead becoming a carrier of water flow resistance and impurity adhesion. At the same time, traditional gates are mostly monolithic structures, making it difficult to flexibly assemble and expand them according to canal width, flow rate, and purification requirements once installed, resulting in poor versatility and adaptability. Therefore, we propose a modular, assembled irrigation canal gate. Summary of the Invention

[0005] The purpose of this invention is to provide a modular, assembled irrigation channel gate to solve the technical problems of traditional irrigation gates having fixed filters that cannot adapt to the purification needs of multiple scenarios and are difficult to flexibly assemble.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a modular assembled irrigation river gate, including a gate support, slide rails arranged on the inner walls of both sides of the gate support, a purification mechanism and an interception component arranged inside the gate support, and a sealing component arranged inside the slide rails. The purification mechanism includes a first gate, a second gate, a third gate, and a filter frame that are slidably and sealingly adapted between the slide rails. The first gate, the second gate, the third gate, and the filter frame are arranged in a stepped manner from front to back. The first gate, the second gate, and the third gate are all provided with hinged plate-shaped sealing structures inside. The first gate, the second gate, and the third gate form a segmented sliding gate. The hinged plate-shaped sealing structure enables the segmented sliding gate to either allow flow or seal. The segmented sliding gate and filter frame can move up and down independently. When cleaning suspended waste on the surface of the irrigation canal, the gates in the segmented sliding gate move upward, forming a step with the minimum height of the ladder with the filter frame, and are connected to the filter frame, which can filter the waste on the surface of the irrigation canal. When cleaning waste in the canal bed, the gates in the segmented sliding gate move downward, forming a step with the maximum height of the ladder with the filter frame, and are connected to the filter frame, which can filter the waste in the canal bed.

[0007] This invention achieves significant purification and operational advantages through a combination design of stepped, segmented sliding gates and filter frames, along with the flow-through or sealing switching function of a hinged plate-shaped sealing structure. It allows for the independent up-and-down movement of the segmented sliding gates, creating a stepped, interconnected structure in the irrigation channel that adapts to the water surface or channel bed, precisely filtering waste from different areas and solving the problem of traditional irrigation gates' inability to simultaneously handle waste from both the water surface and the channel bed. Furthermore, the segmented design and independent movement allow for flexible adaptation to different waste distribution scenarios. Combined with the interception function of the filter frame, this significantly improves the targeting and efficiency of waste purification in irrigation channels. Simultaneously, the sealing structure ensures the stability of gate operation, making the overall design suitable for the complex channel purification needs of irrigation areas.

[0008] Preferably, the purification mechanism further includes several guide rods, all of which are symmetrically connected to the upper surfaces of the first gate, the second gate, the third gate, and the filter frame. The top of the gate support is symmetrically equipped with a hydraulic drive system, and the hydraulic drive system is adapted to the guide rod transmission.

[0009] Preferably, the bottom inner walls of the first gate, the second gate, and the third gate are all hinged with a first baffle, and a second baffle is hinged to one end of each first baffle. The second baffle on the first gate is hinged to the bottom of the second gate, the second baffle on the second gate is hinged to the bottom of the third gate, and the second baffle on the third gate is hinged to the filter frame. A plurality of the first baffles and the second baffles are sealed and adapted to the inside of the first gate, the second gate, and the third gate. By applying force to the second baffle, the second baffle and the first baffle are axially rotated and folded, allowing the segmented sliding gate to flow. By applying force to the second baffle, the second baffle and the first baffle are axially rotated in a straight line, causing the segmented sliding gate to block the water flow.

[0010] Preferably, the interception assembly includes several limiting rods, which are symmetrically connected to the inner walls on both sides of the first gate, the second gate, the third gate, and the filter frame.

[0011] Preferably, a blocking plate is axially rotatable between each pair of the limiting rods, and a waist-shaped frame is symmetrically slidably sleeved between each pair of vertically opposite blocking plates. A first tension spring is symmetrically fixedly connected to the inner walls on both sides of each waist-shaped frame.

[0012] Preferably, each of the waist-shaped frames has two slidably connected blocks inside, and the blocks are fixedly connected to the first tension spring, and the blocks are rotatably sleeved on the surface of the insert rod on the end plate.

[0013] Preferably, each of the waist-shaped frames is fixedly connected to one side with a guide rod, and the guide rod is in movable contact with the first baffle and the second baffle respectively. In this invention, the interception component, through the cooperation of the blocking plate, the waist-shaped frame and the first tension spring, automatically opens the flow space with the water flow when the gate is opened, ensuring that waste enters the filter frame with the water flow; after the gate is stopped, the tension spring drives the blocking plate to reset and close, preventing the intercepted waste from flowing back; the filter frame can be raised and lowered independently, and waste can be easily removed when it is removed from the water surface. Combined with the anti-backflow design of the concave blocking plate, the risk of secondary pollution from garbage is greatly reduced; compared with the traditional filter structure, its closed-loop process of interception, collection and removal is more efficient, reducing the frequency and difficulty of manual cleaning.

[0014] Preferably, the sealing assembly includes a plurality of through holes, which are arranged in a linear array on the inner walls of both sides of the slide rail. Each slide rail is slidably connected to an insert block, and each pair of insert blocks makes sealing contact.

[0015] Preferably, each of the slide rails has several spring pieces fixedly connected in a linear array on one side, and the spring pieces are in movable contact with the end of the insert block.

[0016] Preferably, pulleys are arranged on both sides of the first, second, and third gates and the filter frame, and the pulleys are in active contact with the insert blocks. In this invention, the sealing component automatically cleans residual waste in the slide rail when the gate slides through the linkage of the insert blocks, spring pieces and gate pulleys in the slide rail, avoiding the accumulation of impurities that cause jamming. The sliding seal fit between the gate and the slide rail and the sealing design of the baffle effectively prevent water from leaking through the gaps and ensure the gate control accuracy. At the same time, the hydraulic drive system can independently control the movement of each gate to adapt to the sealing requirements under different flow rates. These structures solve the problem that channel garbage can easily cause gate jamming and sealing failure, and improve the long-term stable operation capability of the device in complex water areas.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves significant purification and operational advantages through a combination design of stepped, segmented sliding gates and filter frames, along with the flow-through or sealing switching function of a hinged plate-shaped sealing structure. Specifically, by controlling the independent up-and-down movement of the segmented sliding gates, a stepped, interconnected structure is formed in the irrigation channel bed to precisely filter waste from different areas, solving the problem of traditional irrigation gates' inability to handle both surface and bed waste. Furthermore, the segmented design and independent movement allow for flexible adaptation to different waste distribution scenarios. Combined with the interception function of the filter frame, this significantly improves the targeting and efficiency of waste purification in irrigation channels. Simultaneously, the sealing structure ensures the stability of gate operation, making the overall design suitable for the complex channel purification needs of irrigation areas.

[0018] 2. This invention achieves precise purification of waste in different areas of irrigation channels through a combination design of stepped gates and filter frames. For suspended garbage on the surface of irrigation channels, the gates can be controlled to form a stepped flow structure, allowing the water flow to carry the garbage through the filter frame for interception. For waste in the channel bed, the direction of the gate steps can be adjusted to guide the flowing waste in the channel bed into the filtration range. At the same time, the height of the filter frame can be adjusted according to the channel water level, adapting to scenarios such as low-flow gate release. This layered purification design solves the problem that traditional irrigation gates cannot simultaneously handle garbage on the water surface and in the channel bed, improving the purification adaptability to different aquatic environments.

[0019] 3. In this invention, the interception component, through the cooperation of the blocking plate, the waist-shaped frame, and the first tension spring, automatically opens the flow space with the water flow in the irrigation channel when the gate is opened, ensuring that waste enters the filter frame with the water flow; after the gate is stopped, the tension spring drives the blocking plate to reset and close, preventing the intercepted waste from flowing back; the filter frame can be raised and lowered independently, and waste can be easily removed when it is removed from the water surface. Combined with the anti-backflow design of the concave blocking plate, the risk of secondary pollution from garbage is greatly reduced; compared with the traditional filter structure, its closed-loop process of interception, collection, and removal is more efficient, reducing the frequency and difficulty of manual cleaning.

[0020] 4. In this invention, the sealing component automatically cleans residual waste in the slide rail when the gate slides through the linkage of the insert block, spring piece and gate pulley in the slide rail, avoiding the accumulation of impurities that cause jamming; the sliding seal fit between the gate and the slide rail and the sealing design of the baffle effectively prevent water from seeping through the gap in the irrigation channel and ensure the accuracy of gate control; at the same time, the hydraulic drive system can independently control the movement of each gate to adapt to the sealing requirements under different flow rates; these structures solve the problem that garbage in the irrigation channel can easily cause gate jamming and sealing failure, and improve the long-term stable operation capability of the device in complex water areas.

[0023] like Figures 1-5 , Figure 8-9 and Figure 12-14 As shown, the present invention relates to a modular assembled irrigation river gate, comprising a gate support 1, slide rails 11 arranged on the inner walls of both sides of the gate support 1, a purification mechanism 2 and an interception assembly 3 arranged inside the gate support 1, and a sealing assembly 4 arranged inside the slide rails 11.

[0024] It is worth noting that the gate support 1 adopts a modular assembly frame structure, and its width can be divided and combined according to the actual size of the irrigation channel. Multiple support units can be horizontally spliced ​​through standardized flange connection interfaces to adapt to the installation needs of irrigation channels with different spans.

[0025] The purification mechanism 2 includes a first gate 21, which is slidably and sealed between two slide rails 11. A second gate 22 is slidably and sealed between the two slide rails 11, and a third gate 23 is slidably and sealed between the two slide rails 11. A filter frame 24 is slidably and sealed between the two slide rails 11. The first gate 21, second gate 22, third gate 23, and filter frame 24 are arranged in a stepped manner from front to back. The first gate 21, second gate 22, and third gate 23 form a segmented sliding valve. This segmented sliding valve, as an independent functional module unit, can be selected and equipped with one or more sets according to the purification needs of the irrigation channel, realizing a flexible configuration from single-stage purification to multi-stage series purification. The first gate 21, second gate 22, third gate 23, and the upper surface of the filter frame 24 are all symmetrically and fixedly connected. A guide rod 25 is attached to the top of the gate bracket 1, and a hydraulic drive system 26 is symmetrically arranged on the top. The hydraulic drive system 26 is adapted to the guide rod 25. The hydraulic drive system 26 also adopts a modular design, and each drive unit can independently control the corresponding gate module without interfering with each other. The bottom inner walls of the first gate 21, the second gate 22 and the third gate 23 are all hinged with a first baffle 27. One end of each first baffle 27 is hinged with a second baffle 28. The second baffle 28 on the first gate 21 is hinged to the bottom of the second gate 22. The second baffle 28 on the second gate 22 is hinged to the bottom of the third gate 23. The second baffle 28 on the third gate 23 is hinged to the filter frame 24. Several first baffles 27 and second baffles 28 are sealed and adapted to the inside of the first gate 21, the second gate 22 and the third gate 23.

[0026] It is worth noting that the hydraulic drive system 26 is a conventional technology and will not be described in detail here. It moves the guide rod 25 up or down via gas and can be independently controlled, so that the first gate 21, the second gate 22, the third gate 23 and the filter frame 24 can move independently. The independent lifting characteristics of each gate module allow them to maintain their own degree of freedom of movement after assembly and do not restrict each other.

[0027] Specifically, the hydraulic drive system 26 drives the first gate 21, the second gate 22, the third gate 23, and the filter frame 24 to move up and down. When purifying the suspended debris on the surface of the irrigation canal and when it is necessary to release the gates, the first gate 21, the second gate 22, and the third gate 23 all move upwards, causing them to form a stepped shape with the filter frame 24, with the step height at its minimum. This allows the segmented sliding valves to connect with the filter frame 24, and the irrigation canal water flows through the stepped flow path and through the filter frame 24, filtering out the suspended debris on its surface. The canal bed is then purified. When waste is discharged, the second gate 22, the third gate 23, and the filter frame 24 all move downwards, making them connected to the first gate 21 in a stepped manner, and the maximum height of the stepped section is reached, which can purify the waste flowing on the channel bed. When the first gate 21, the second gate 22, the third gate 23, and the filter frame 24 are in a stepped manner and the stepped section is at its highest, the first gate 21, the second gate 22, the third gate 23, and the filter frame 24 do not flow, which can block the flow of water in the irrigation channel. At the same time, the filter frame 24 can be adjusted according to the height of the water surface in the irrigation channel.

[0028] In modular assembly applications, depending on the actual width of the irrigation canal and the required purification level, one or more purification mechanisms 2 can be installed side by side in the gate bracket 1. Each module is quickly connected and sealed through the standard interface of the slide rail 11, ensuring the stability of the overall structure after assembly and the coordination of the actions between each module. When a section of the irrigation canal does not require purification function, the gate module at the corresponding position can be replaced with a sealing plate module of the same size, realizing the on-demand selection of functions.

[0029] This invention achieves precise purification of waste in different areas of irrigation channels through the combined design of a stepped gate and a filter frame 24. For suspended garbage on the surface of the irrigation channel, the gate can be controlled to form a stepped flow structure, allowing the water flow to carry the garbage and intercept it through the filter frame 24. For waste in the channel bed, the direction of the gate steps can be adjusted to guide the flowing waste in the channel bed into the filtration range. At the same time, the height of the filter frame 24 can be adjusted according to the channel water level, adapting to scenarios such as small-flow gate release. This layered purification design solves the problem that traditional irrigation gates cannot simultaneously handle garbage on the water surface and in the channel bed, improving the purification adaptability to different irrigation water environments.

[0030] like Figures 6-7As shown, the interception component 3 includes several limiting rods 31. The limiting rods 31 are symmetrically connected to the inner walls of the first gate 21, the second gate 22, the third gate 23 and the filter frame 24 on both sides. After assembly, the interception components 3 on each gate module form a continuous interception working surface. The blocking plates 32 and waist-shaped frames 33 between adjacent modules are connected through standard interfaces to ensure a seamless transition of the interception effect. A blocking plate 32 rotates axially between each pair of limiting rods 31. A waist-shaped frame 33 is symmetrically slidably sleeved between each pair of vertically opposite blocking plates 32. A first tension spring 34 is symmetrically connected to the inner walls on both sides of each waist-shaped frame 33. Two abutments 35 are slidably connected inside each waist-shaped frame 33, and the abutments 35 are fixedly connected to the first tension spring 34. The abutments 35 are also rotatably sleeved on the insert rod surface on the blocking plate 32. A guide rod 331 is fixedly connected to one side of each waist-shaped frame 33, and the guide rod 331 is in movable contact with the first baffle 27 and the second baffle 28 respectively.

[0031] It is worth noting that the surface of the limiting rod 31 has an arc-shaped block that can limit the rotation angle of the blocking plate 32, which is used to adjust the flow space between the two blocking plates 32.

[0032] Specifically, during the gate release process, the water flow in the irrigation channel causes the two relatively blocking plates 32 to rotate axially and flow out of the flow space. The channel water and waste flow through the flow space and separate at the filter frame 24, filtering the waste inside the filter frame 24. When the gate release is stopped, the filter frame 24 moves upward and can remove the waste from the filter frame 24. When the filter frame 24 is lifted off the water surface, the first tension spring 34 rotates the two relatively blocking plates 32 axially to prevent the waste from being moved out of the filter frame 24.

[0033] In this invention, the interception component 3, through the cooperation of the blocking plate 32, the waist-shaped frame 33, and the first tension spring 34, automatically opens the flow space with the water flow in the irrigation channel when the gate is opened, ensuring that waste enters the filter frame 24 with the water flow; after the gate is stopped, the tension spring drives the blocking plate 32 to reset and close, preventing the intercepted waste from flowing back; the filter frame 24 can be raised and lowered independently, and waste can be easily removed when it is removed from the water surface. Combined with the anti-backflow design of the concave blocking plate 32, the risk of secondary pollution from garbage is greatly reduced; compared with the traditional filter structure, its closed-loop process of interception, collection, and removal is more efficient, reducing the frequency and difficulty of manual cleaning.

[0034] like Figure 11As shown, the sealing assembly 4 includes several through holes 41, which are arranged in a linear array on the inner walls of both sides of the slide rail 11. Each slide rail 11 has a sliding block 42 inside, and each pair of opposite blocks 42 are in sealing contact. Each slide rail 11 has several spring pieces 43 fixedly connected in a linear array on one side, and the spring pieces 43 are in movable contact with the ends of the blocks 42. The first gate 21, the second gate 22, the third gate 23 and the filter frame 24 are all equipped with pulleys 44 on both sides, and the pulleys 44 are in movable contact with the blocks 42. The sealing assembly 4 is also continuously arranged at the joints of each assembly module to ensure the consistency of the water tightness at the assembly joints and the self-cleaning function inside the slide rail.

[0035] Specifically, when the first gate 21, the second gate 22, the third gate 23 and the filter frame 24 slide on the slide rail 11, the arrangement of several slidable inserts 42 can prevent waste from remaining in the inactive area of ​​the slide rail 11 and avoid blockages such as movement jamming.

[0036] In this invention, the sealing component 4, through the linkage between the insert block 42 and the spring piece 43 in the slide rail 11 and the gate pulley 44, automatically cleans residual waste in the slide rail 11 when the gate slides, avoiding the accumulation of impurities that cause jamming; the sliding seal adaptation between the gate and the slide rail 11 and the sealing design of the baffle effectively prevent water from leaking through the gaps, ensuring the gate control accuracy; at the same time, the hydraulic drive system 26 can independently control the movement of each gate to adapt to the sealing requirements under different flow rates; these structures solve the problem that garbage in irrigation channels can easily cause gate jamming and sealing failure, and improve the long-term stable operation capability of the device in complex water areas.

[0037] Working principle: This embodiment provides a modular assembly irrigation canal gate. During installation, firstly, based on the width of the irrigation canal and the purification requirements, determine the number of modules of the required purification mechanism 2. Then, horizontally splice the corresponding number of gate support units 1 through flange interfaces. Finally, install each gate module (first gate 21, second gate 22, third gate 23) and filter frame 24 into the corresponding slide rails 11 to complete the overall assembly. When in use, first observe the condition of waste on the water surface or canal bed of the irrigation canal, and then adjust the gate.

[0038] Cleaning of waste in the canal bed, such as Figure 13As shown, the hydraulic drive system 26 first drives the guide rod 25, causing the second gate 22, the third gate 23, and the filter frame 24 to move downwards along the slide rail 11. At this time, the pulley 44 can push the two opposing inserts 42 to move in opposite directions. After adjustment, the two opposing inserts 42 in contact can prevent waste from entering the slide rail 11, avoiding motion interference and affecting the normal operation of the device. The second baffle 28 applies force through the adjacent valve, and applies force through the guide rod 331 to the gap between the second baffle 28 and the first baffle 27, causing the first... The second baffle 28 rotates and folds axially with the first baffle 27, and several second baffles 28 rotate axially with the second gate 22, the third gate 23, and the filter frame 24, causing the first gate 21, the second gate 22, the third gate 23, and the filter frame 24 to form a stepped structure with the largest step height. The water flow causes the blocking plate 32 to rotate axially, which increases the gap between the two blocking plates 32. The channel water flows in from this space and flows through the filter frame 24. Waste is blocked inside the filter frame 24, and the concave blocking plate 32 can prevent the waste from flowing back. Cleaning and purification of waste on the surface of irrigation canals, such as... Figure 12 and Figure 14 As shown: First, the hydraulic drive system 26 drives the guide rod 25, causing the first gate 21, the second gate 22, and the third gate 23 to move upward along the slide rail 11. The pulley 44 pushes the insert block 42 to move. Then, the spring piece 43 closes, which can prevent waste from entering the slide rail 11 and affecting the operation of the valve. At the same time, the second baffle 28 applies force through the adjacent valve, and the guide rod 331 applies force to the gap between the second baffle 28 and the first baffle 27, causing the second baffle 28 and the first baffle 27 to rotate axially and fold. Furthermore, several second baffles 28 rotate axially with the first gate 21, the second gate 22, and the third gate 23, causing the first gate 21, the second gate 22, the third gate 23, and the filter frame 24 to form a stepped structure with the minimum height of the ladder. At this time, the filter frame 24 is located at the water surface. Through the flow of water, it drives the block plate 32 to rotate axially, causing the gap between the two block plates 32 to increase. The channel water flows in from this space and flows through the filter frame 24. Waste is blocked inside the filter frame 24, and the concave block plate 32 can prevent the waste from flowing back.

[0039] Purification valve adjustment, such as Figure 12 As shown: When adjusting the position of the filter frame 24, the height of the filter frame 24 is first adjusted by the hydraulic drive system 26. At this time, the filter frame 24 applies a force to the second baffle 28 on the third gate 23, causing the second baffle 28 and the first baffle 27 to rotate axially and fold, so that the filter frame 24 is connected to the third gate 23, so that its flow space corresponds to the water surface position. This is suitable for small flow gate release and irrigation canal water purification treatment.

[0040] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
