Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering gate with a filtration function. Background Technology

[0002] Water conservancy is the lifeblood of agriculture. Rural farmland irrigation water conservancy projects, as important infrastructure to ensure national food security, are directly related to farmland irrigation efficiency and crop yield. Among them, water gates are the core control components of the irrigation system, playing a key role in regulating water flow, distributing water volume, and blocking or releasing water flow. According to statistics, the irrigated area of ​​farmland in my country has reached 1.09 billion mu, of which a very high proportion of farmland is covered by small rural irrigation canal systems. The water gates in these canal systems are mostly small and simple structures, widely distributed in the fields, adapted to the water flow characteristics and installation conditions of rural irrigation canals. The normal operation of these gates is an important guarantee for achieving precision irrigation, reducing water waste, and alleviating the pressure of drought and flood on farmland. Their performance directly affects the water conveyance efficiency of the irrigation system, which in turn affects the stability of rural agricultural production and farmers' economic income. They are also a support for promoting the construction of high-standard farmland and assisting important water conservancy facilities.

[0003] However, in practice, we have found that the sluice gates used in rural irrigation canals generally suffer from insufficient floating debris handling capacity, making it difficult to meet actual irrigation needs. Existing gates are mostly equipped with simple steel bar grids or wire mesh as basic debris-blocking structures, which can only initially intercept large floating debris and cannot further process common floating debris such as straw, aquatic plants, dead branches and leaves, and plastic bags. These floating debris accumulate in front of the gate, easily clogging the debris-blocking structure and the gaps between the gate and the sluice gate, resulting in a reduced water flow cross-section, decreased irrigation efficiency, and even jamming of the gate, affecting its normal opening and closing. At the same time, the existing treatment methods mainly rely on manual cleaning, which is not only labor-intensive and inefficient, but also lacks professional maintenance personnel in rural areas. During the busy farming season, no one is available to take care of the cleaning work, resulting in long-term accumulation of floating debris. Therefore, we propose a sluice gate with a debris-filtering function for water conservancy projects. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to effectively address the issues of reduced flow cross-section, sluggish opening and closing, and high frequency and low efficiency of manual cleaning caused by the accumulation of floating debris such as straw, aquatic plants, dead branches and leaves, and plastic bags in small rural irrigation canals.

[0012] In some embodiments, the water filtration assembly includes a storage member disposed on the side of the gate body near the release plate, which stores the debris collected by the collecting rake, and a squeezing member disposed on the side of the gate body near the release plate, which squeezes out the water from the collected debris.

[0013] In some embodiments, the storage component includes a storage frame disposed between the two adjustment frames. The storage frame has multiple drainage holes at its bottom. Positioning plates are provided on both sides of the storage frame. The two positioning plates are respectively attached to the side of the two adjustment frames away from the gate bracket.

[0015] This invention has at least the following beneficial effects: 1. The interceptor plate combined with the collection rake is not only efficient in cleaning debris but also prevents clogging. The inclined interceptor plate with the flow channel can intercept floating debris without affecting the water flow. The scraping collection of the collection rake can prevent debris from accumulating and ensure the normal operation of the gate. At the same time, it has strong adaptability to working conditions. The adjustment component can flexibly adjust the tilt angle of the interceptor plate to adapt to different water flow depths, flow velocities and debris distribution scenarios. Moreover, the structure is stable, the installation and modification are convenient, and the frequency of manual inspection and dredging is significantly reduced.

[0016] 2. Achieve energy-saving self-driving and automatic circulation collection. The impeller assembly uses water flow power to provide collection power, eliminating the need for an external power source. This saves energy, is environmentally friendly, and reduces operation and maintenance costs. The transmission components drive the collection rake to reciprocate longitudinally, while the detachment components assist in the automatic detachment of debris, enabling periodic automatic collection of debris. This significantly reduces the frequency of manual cleaning and improves operation and maintenance efficiency.

[0017] 3. The water filtration and volume reduction effect is outstanding. The water filtration component drains water through the collection frame and squeezes water out of the impurities through the extrusion component, so that the water in the impurities flows back, reducing the volume of the impurities, avoiding secondary pollution, and facilitating subsequent cleaning. In addition, the equipment integrates water control, impurity filtration, automatic collection, and dehydration into one integrated function, without occupying additional water conservancy space, and is suitable for rural water conservancy scenarios.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figure 1-12 The present invention provides a technical solution: a gate for water conservancy projects with a filtering function, comprising a gate support 1 and a gate body 2, and further comprising: The interceptor plate 3 is installed on one side of the gate body 2 and located at the water outlet to intercept floating debris in the water. The collecting rake 4 is set below the interceptor plate 3 and works in conjunction with the interceptor plate 3 to collect floating debris trapped by the interceptor plate 3; Adjusting component 5 is set on one side of gate bracket 1 and located at water outlet. It is used to adjust the tilt angle of interceptor plate 3, thereby adjusting the angle between interceptor plate 3 and water flow direction to be suitable for intercepting debris of different depths in water flow. The collection component 6 is located on the side of the interceptor plate 3 away from the gate body 2. The collection component 6 drives the collection rake 4 to move longitudinally back and forth, thereby driving the collection rake 4 to scrape and collect floating debris on one side of the interceptor plate 3. The water filtration assembly 7 is installed above the interceptor plate 3. The water filtration assembly 7 is used to dehydrate and initially separate the debris collected by the collecting rake 4, so that the water in the debris is separated from the debris and re-enters the water flow.

[0022] Multiple flow channels 31 for water flow are equidistantly provided on the interceptor plate 3, and the interceptor plate 3 is inclined, with its top forming an upward angle with the surface of the interceptor plate 3. The multiple flow channels 31 are used in conjunction with the collection rake 4. The multiple flow channels 31 can cooperate with the longitudinal scraping action of the collection rake 4 to lift the debris on the surface of the interceptor plate 3 upward through the edge of the opening of the flow channel 31, thereby causing the debris to detach from contact with the interceptor plate 3.

[0023] The adjusting component 5 includes two adjusting brackets 51 disposed on the side of the gate bracket 1 near the intercepting plate 3. Each adjusting bracket 51 has multiple adjusting holes 52 equidistantly spaced, and adjusting grooves 53 are provided on both sides of each adjusting bracket 51. Two auxiliary plates 54 are disposed on the side of each adjusting bracket 51 away from the gate bracket 1. Of the four auxiliary plates 54, the two upper auxiliary plates 54 have a first rotating plate 55 rotatably mounted on their ends away from the two adjusting brackets 51 via a rotating shaft, while the two lower auxiliary plates 54 have a first rotating plate 55 rotatably mounted on their ends away from the two adjusting brackets 51. A second rotating plate 56 is rotatably provided via a rotating shaft. The ends of the two first rotating plates 55 away from the gate body 2 are rotatably connected to the adjacent second rotating plate 56 via a rotating shaft. The two ends of the intercepting plate 3 are respectively located on the opposite sides of the two second rotating plates 56. The four auxiliary plates 54 are each provided with two adjusting wheels 57 rotatably provided via a rotating shaft on the side near the two adjusting frames 51. The eight adjusting wheels 57 are respectively used in conjunction with the four corresponding adjusting slots 53. The four auxiliary plates 54 are also in contact with the two adjacent adjusting frames 51 on the side near the two adjusting frames 51. Each of the four auxiliary plates 54 has a locking block 58 on the side away from the interceptor plate 3. A locking rod 59 is slidably installed within each of the four locking blocks 58, and each locking rod 59 passes through the corresponding auxiliary plate 54 and cooperates with the adjacent adjustment hole 52. An adjustment handle 510 is installed at the opposite end of each of the four locking rods 59. A locking spring 511 is installed on the outside of each of the four locking rods 59, and the other end of each locking spring 511 is respectively installed within the corresponding locking block 58. When the operator completes the filtration of the water flow and needs to close the gate body 2, the storage frame 111 can be removed first in the above manner, and then pulled... Move the two uppermost adjustment handles 510 so that the adjustment handles 510 drive the locking rods 59 to disengage from the corresponding adjustment holes 52. Then push the corresponding auxiliary plates 54 upward so that the two uppermost auxiliary plates 54 and the adjustment wheel 57 slide upward along the adjustment frame 51 and the adjustment groove 53 until the two uppermost auxiliary plates 54 disengage from the top of the adjustment frame 51. Then, following the above method, pull the two lower adjustment handles 510 in sequence so that the remaining locking rods 59 disengage from the corresponding adjustment holes 52 and all auxiliary plates 54 slide upward along the adjustment frame 51 and the adjustment groove 53 in sequence and disengage. If it is necessary to adjust the tilt angle of the interceptor plate 3 so that it can intercept debris at different depths of the water flow, the two lowest adjustment handles 510 can be pulled simultaneously. This will cause the two lowest adjustment handles 510 to drive the corresponding locking rods 59 to disengage from the adjustment holes 52. Then, the two lowest auxiliary plates 54 are pulled downwards. At this time, the two first rotating plates 55 and the second rotating plate 56 rotate through their respective pivots at opposite ends, thereby changing the tilt angle of the two second rotating plates 56. Since the interceptor plate 3 is located on the opposite side of the two second rotating plates 56, the tilt angle of the interceptor plate 3 changes synchronously when the angle of the two second rotating plates 56 changes. When the staff confirms that the interceptor plate 3 has reached the preset tilt angle, the adjustment handles 510 are released. The locking rods 59 are automatically inserted into the corresponding adjustment holes 52 under the action of the locking springs 511, thereby achieving precise adjustment and reliable locking of the tilt angle of the interceptor plate 3.

[0024] The collection component 6 includes a drive unit 8 disposed on one side of the two adjustment frames 51. The drive unit 8, in conjunction with the water flow, generates the power required for the movement of the collection rake 4. A transmission unit 9 is disposed on the side of the collection rake 4 away from the gate body 2. The transmission unit 9 transmits the power required for the collection rake 4 and drives the collection rake 4 to reciprocate longitudinally. A release unit 10 is disposed above the collection rake 4. The release unit 10 drives the debris collected on the collection rake 4 to detach from the collection rake 4, thereby driving the collection rake 4 to perform longitudinal reciprocating motion again, so as to complete the periodic collection and transportation of debris.

[0025] The driving component 8 includes driving brackets 81 respectively disposed at the bottom of the two lower auxiliary plates 54 among the four auxiliary plates 54. The ends of the two driving brackets 81 near the two adjusting frames 51 are respectively attached to the two adjusting frames 51. A horizontal plate 82 is disposed on the opposite side of the two driving brackets 81. A vertical plate 83 is disposed in the middle section of the horizontal plate 82. A bearing 84 is disposed at the bottom end of the vertical plate 83. A driving shaft 85 is disposed at the center of the bearing 84 and is rotatably disposed at the bottom end of the vertical plate 83 through the bearing 84. A driving impeller assembly 86 is disposed at the end of the driving shaft 85 near the interceptor plate 3. When the driving impeller assembly 86 is impacted by the water flow and rotates, the driving impeller assembly 86 will drive the driving shaft at its center. The drive shaft 85 rotates together with the transmission plate 91 on its outer side, thereby causing the drive shaft 85 to rotate together with the transmission plate 91 on its outer side. The bearing 84 set on the outer side of the drive shaft 85 can effectively reduce the frictional resistance between the drive shaft 85 and the vertical plate 83, ensuring the smoothness of the rotational movement of the drive shaft 85 and the transmission efficiency. The drive bracket 81, together with the horizontal plate 82, can ensure the structural stability and vertical positioning of the vertical plate 83, thereby ensuring the smoothness of the rotational movement of the drive shaft 85 and the transmission efficiency. Its function is to use the water flow impact to drive the impeller assembly 86 to generate rotational power, and transmit this power to the transmission component 9 via the drive shaft 85, thereby providing a continuous and stable mechanical driving force for the longitudinal reciprocating motion of the collecting rake 4.

[0026] Transmission component 9 includes a transmission plate 91 disposed at the end of the drive shaft 85 away from the drive impeller assembly 86. A connecting plate 92 is rotatably disposed at the bottom end of the transmission plate 91 via a rotating shaft. A transmission shaft 93 is rotatably disposed at the top end of the connecting plate 92. A rectangular groove 94 is formed on the vertical plate 83. A rectangular plate 95 is slidably disposed in the rectangular groove 94. A clamping piece 96 is disposed at one end of the rectangular plate 95 near the transmission shaft 93, and a control plate 97 is disposed at the other end. One end of the transmission shaft 93 is disposed on the clamping piece 96. A bolt 98 is disposed at the top end of the control plate 97, and a mounting plate is disposed at the top end of the control plate 97. Mounting plate 99 and control plate 97 are connected by bolts 98. The collecting rake 4 is located at the end of mounting plate 99 furthest from control plate 97. Clamping plates 96 and control plate 97 are respectively attached to the sides of upright plate 83. When transmission plate 91 rotates under the drive of drive shaft 85, its other end will also rotate around drive shaft 85. At this time, the rotating transmission plate 91 will push the connecting plate 92 rotatably connected to its end, causing the end of connecting plate 92 furthest from transmission plate 91 to move up and down. When connecting plate 92 is pushed by the transmission plate 91... During operation, the top of the rectangular plate 95 is pushed by the rotating shaft to drive the clamping plate 96, causing the clamping plate 96 to slide the rectangular plate 95 within the rectangular groove 94. This, in turn, causes the rectangular plate 95 to slide longitudinally back and forth along the rectangular groove 94. The clamping plate 96 and the control plate 97 firmly hold the rectangular plate 95 within the rectangular groove 94, maintaining axial stability during its longitudinal reciprocating motion and preventing displacement or jamming. As the rectangular plate 95 slides longitudinally back and forth along the rectangular groove 94, the control plate 97 at one end moves along with it. The control plate 97 is secured by bolts. 98 drives the mounting plate 99 to slide longitudinally back and forth along the rectangular groove 94 following the rectangular plate 95, thereby causing the mounting plate 99 to drive the collecting rake 4 to slide longitudinally back and forth. The bolt 98 set between the mounting plate 99 and the control plate 97 can facilitate the disassembly of the collecting rake 4 when it needs to be repaired or replaced, thereby realizing the quick disassembly and on-site maintenance of the collecting rake 4. Its function is to convert the rotational power of the drive impeller assembly 86 into the longitudinal reciprocating motion of the collecting rake 4 following the rectangular groove 94, thereby realizing the periodic scraping and conveying of debris on the surface of the intercepting plate 3 by the collecting rake 4.

[0027] The detachment component 10 includes a detachment bracket 101 disposed on the side of the two drive brackets 81 near the gate body 2. A detachment shaft 102 is rotatably disposed on the two detachment brackets 101. A detachment plate 103 is disposed on the outer side of the detachment shaft 102. Multiple detachment grooves 104 are equally spaced on the detachment plate 103. The collecting rake 4 is used in cooperation with the detachment plate 103 through the multiple detachment grooves 104. A torsion spring 105 is disposed at both ends of the detachment shaft 102. The other ends of the two torsion springs 105 are respectively disposed in the adjacent detachment brackets 101. A limit plate 106 is disposed at both ends of the detachment plate 103. The opposite ends of the two limit plates 106 are respectively attached to the top of the adjacent detachment brackets 101. The end of the detachment plate 103 away from the gate body 2 is inclined upward. As the collecting rake 4 reciprocates up and down, it passes over the intercepting plate 3 from bottom to top and through multiple flow grooves 31 on the intercepting plate 3. This allows the collecting rake 4 to scrape away debris adhering to the surface of the intercepting plate 3. Then, as the collecting rake 4 continues to rise, it carries debris through the release plate 103. Because the collecting rake 4 is carrying debris, it cannot pass through the multiple release grooves 104 on the release plate 103 to reach the top of the release plate 103. Consequently, the collecting rake 4, carrying debris, lifts the release plate 103, causing it to rotate on the release support 101 via the release shaft 102. At this time, the torsion springs 105 at both ends of the release shaft 102 begin to store and compress until the debris is collected. The collecting rake 4 rises to the highest point of the release plate 103, causing it to disengage from the release plate 103. At this point, the torsion spring 105 releases its elastic potential energy, driving the release plate 103 to quickly reset and press down. The limiting plates 106 on both sides of the release plate 103 then strike the top of the corresponding release brackets 101, thereby limiting the reset angle of the release plate 103 and preventing it from becoming too large and thus unable to continue working with the collecting rake 4. After the release plate 103 resets, the rectangular plate 95 also reaches the top of the rectangular groove 94, thus preventing it from rising further. The collecting rake 4 carrying debris also cannot move upwards. At this point, the transmission plate 91 continues to rotate, while the rectangular plate 95 moves downwards along the rectangular groove 94. The movement of the rake causes the collecting rake 4 to move downwards. As the collecting rake 4 passes the release plate 103, it slowly passes through the release groove 104 and reaches below the release plate 103. The debris on the collecting rake 4 is intercepted by the release plate 103. The purpose of this is to use the collecting rake 4 to carry the debris and transport it above the release plate 103, causing the release plate 103 to rotate. This allows the debris on the release plate 103 to slide along its inclined surface into the collection frame 111. As the collecting rake 4 descends past the release plate 103, the multiple release grooves 104 on the release plate 103 separate the debris from the collecting rake 4 during its descent.This achieves the dual purpose of collecting and separating debris: on the one hand, the inclined surface of the release plate 103 enables the directional sliding and conveying of debris to the collection frame 111; on the other hand, the gap between the release groove 104 and the collection rake 4 ensures reliable separation of debris from the collection rake 4 during its descent.

[0028] The water filtration assembly 7 includes a storage component 11 disposed on the side of the gate body 2 near the release plate 103, which stores the debris collected by the collection rake 4. A squeezing component 12 is disposed on the side of the gate body 2 near the release plate 103, which squeezes out the water from the collected debris.

[0029] The storage component 11 includes a storage frame 111 disposed between two adjusting brackets 51. The storage frame 111 has multiple drainage holes 112 at its bottom. Positioning plates 113 are provided on both sides of the storage frame 111. The two positioning plates 113 are respectively attached to the side of the two adjusting brackets 51 away from the gate support 1. Two positioning wheels 114 are rotatably mounted on the end of each positioning plate 113 near the two adjusting brackets 51 via a rotating shaft. Each of the four positioning wheels 114 engages with a corresponding adjusting groove 53. Fixing blocks 115 are provided on the opposite sides of the two positioning plates 113. Two fixing rods 116 are slidably installed inside the 15. Each fixing rod 116 passes through an adjacent positioning plate 113 and engages with a corresponding adjusting hole 52. A fixing handle 117 is provided at the opposite ends of each fixing rod 116. A fixing spring 118 is provided on the outer side of each fixing rod 116, with the other end of each fixing spring 118 located within a corresponding fixing block 115. As the squeezing plate 122 squeezes the debris, the moisture in the debris gradually separates and is discharged through the drain hole 112, thereby reducing the moisture content of the debris. This step not only expands the area of ​​the debris... The storage space effectively compresses the volume of debris, reduces the subsequent cleaning load, and improves overall operational efficiency. When the storage box 111 is full of debris, the staff can pull the two fixed handles 117, causing the fixed handles 117 to drive the corresponding fixed rods 116 away from the adjustment hole 52. Then, the storage box 111 is pulled, causing it to slide along the adjustment frame 51 and adjustment groove 53 via the positioning plate 113 and positioning wheel 114 until the storage box 111 is completely detached from the adjustment frame 51. The debris in the storage box 111 is then emptied into the designated cleaning area. The entire process of filtering, collecting, dehydrating, and transferring impurities is closed-loop. If it is necessary to continue collecting impurities from the water, the empty collection frame 111 can be pushed back into the adjustment frame 51 along the adjustment groove 53 until the collection frame 111 reaches the preset position. Then, the fixing spring 118 will push the fixing rod 116 into the corresponding adjustment hole 52, thereby realizing the automatic locking and positioning of the collection frame 111. Its function is to ensure the positioning stability of the collection frame 111 on the adjustment frame 51 and the reliability of repeated loading and unloading, improve the cleaning efficiency and operational safety, and reduce the frequency of manual intervention and operational complexity.

[0030] The extrusion member 12 includes multiple extrusion rods 121 that are slidably and equidistantly arranged on the top of the storage frame 111. Extrusion plates 122 are provided at the bottom ends of the multiple extrusion rods 121. Extrusion springs 123 are provided on the outer sides of each of the multiple extrusion rods 121, with the two ends of each spring respectively located on the top of the extrusion plate 122 and on the storage frame 111. Synchronizing rods 124 are provided at the top ends of the multiple extrusion rods 121. Two triangular plates 125 are slidably arranged on the top of the storage frame 111, and these two triangular plates 125 cooperate with the synchronizing rods 124. The two triangular plates 125 are located on the side closest to the gate body 2. Each of the two triangular plates 125 is equipped with a snap plate 126, which is used in conjunction with the storage frame 111. Each of the two triangular plates 125 has a trigger plate 127 at its end away from the snap plates 126, and both trigger plates 127 are used in conjunction with a release plate 103. During the rotation of the release plate 103, its top end contacts the trigger plate 127. At this time, the trigger plate 127 is pressed by the release plate 103, thus pushing the trigger plate 127. Subsequently, the trigger plate 127 pushes the corresponding triangular plate 125, causing the triangular plate 125 to slide on the top of the storage frame 111. As plate 125 continues to slide, its inclined surface at the top will lift the synchronizing rod 124, which in turn will drive multiple pressing rods 121 to move upwards synchronously. At this time, pressing plate 122 will also move upwards along with synchronizing rod 124, and pressing spring 123 will be compressed synchronously, providing a reverse reset driving force for the elastic potential energy storage of pressing spring 123. When the detachment plate 103 resets under the action of torsion spring 105, the debris on the detachment plate 103 will slide into the storage frame 111, and the elastic potential energy stored in pressing spring 123 will be released, thereby pushing the pressing plate. 122 moves rapidly downwards, applying pressure to the debris that has fallen into the storage box 111. Triangle plate 125 slides backwards as compression spring 123 returns to its original position, and synchronizing rod 124 descends accordingly. Buckle plate 126 at one end of triangle plate 125 restricts the return position of triangle plate 125, preventing triangle plate 125 from over-resetting and losing contact with synchronizing rod 124. Its function is to perform reciprocating mechanical compression on the debris in storage box 111 through compression plate 122, so as to efficiently extract and discharge moisture, thereby reducing the moisture content of debris and reducing the subsequent transfer volume.

[0031] In use, when the operator needs to open the gate body 2 for farmland irrigation, the water flow passes through the gate body 2 and then through the drive impeller assembly 86, impacting it and causing it to rotate. It should be noted that the drive impeller assembly 86 is existing technology and will not be elaborated upon here. When the drive impeller assembly 86 is impacted and rotates by the water flow, it drives the drive shaft 85 at its axis to rotate as well. This causes the drive shaft 85 to drive the transmission plate 91 on its outer side to rotate as well. The bearing 84 located on the outer side of the drive shaft 85 effectively reduces the frictional resistance between the drive shaft 85 and the vertical plate 83, ensuring the smoothness and transmission efficiency of the drive shaft 85's rotation. The drive bracket 81 works in conjunction with the horizontal plate 8... 2. This ensures the structural stability and vertical positioning of the upright plate 83, thereby ensuring the smoothness and transmission efficiency of the rotational movement of the drive shaft 85. When the transmission plate 91 rotates under the drive of the drive shaft 85, its other end will also rotate around the drive shaft 85. At this time, the rotating transmission plate 91 will push the connecting plate 92 connected to its end, causing the end of the connecting plate 92 away from the transmission plate 91 to move up and down. When the connecting plate 92 moves under the thrust of the transmission plate 91, its top end will push the clamping plate 96 through the rotating shaft, causing the clamping plate 96 to drive the rectangular plate 95 to slide in the rectangular groove 94, thereby causing the rectangular plate 95 to slide back and forth longitudinally along the rectangular groove 94. The clamping plate 96 and the control plate 97 can firmly clamp the rectangular plate 95 in the rectangular groove 94. Within the groove 94, the rectangular plate 95 maintains axial stability as it slides longitudinally back and forth within the rectangular groove 94, preventing offset or jamming. When the rectangular plate 95 slides longitudinally back and forth along the rectangular groove 94, the control plate 97 at one end moves along with the rectangular plate 95. The control plate 97, via bolt 98, drives the mounting plate 99 to slide longitudinally back and forth along the rectangular groove 94 along with the rectangular plate 95. This causes the mounting plate 99 to drive the collecting rake 4 to slide longitudinally back and forth. The bolt 98, located between the mounting plate 99 and the control plate 97, facilitates disassembly by workers when the collecting rake 4 needs maintenance or replacement, enabling quick disassembly and on-site maintenance of the collecting rake 4. During the up-and-down reciprocating motion of the collecting rake 4, the collecting rake 4 passes through the intercepting plate 3 from bottom to top. Multiple flow channels 31 on the plate allow the collecting rake 4 to collect debris adhering to the surface of the intercepting plate 3. As the collecting rake 4 continues to rise, it carries debris through the release plate 103. Because the collecting rake 4 carries debris, it cannot pass through the multiple release channels 104 on the release plate 103 to reach the top of the release plate 103. Consequently, the collecting rake 4, carrying debris, lifts the release plate 103, causing it to rotate on the release support 101 via the release shaft 102. At this point, the torsion springs 105 at both ends of the release shaft 102 begin to compress and store energy until the collecting rake 4 rises to the highest point of the release plate 103, causing it to detach from the release plate 103. Then, the torsion springs 105 release their elastic potential energy.The drive release plate 103 quickly resets and presses down, while the limiting plates 106 on both sides of the release plate 103 strike the top of the corresponding release bracket 101, thereby limiting the reset angle of the release plate 103. This prevents the release plate 103 from resetting too far, which would prevent it from continuing to cooperate with the collecting rake 4. After the release plate 103 resets, the rectangular plate 95 also reaches the top of the rectangular groove 94, thus preventing it from rising further. The collecting rake 4 carrying debris also cannot continue to move upward. At this time, the transmission plate 91 continues to rotate. The rectangular plate 95 moves downward along the rectangular groove 94, causing the collecting rake 4 to move downward as well. When the collecting rake 4 passes the release plate 103, it slowly passes through the release groove 104 and reaches below the release plate 103. The debris on the collecting rake 4 is intercepted by the release plate 103. The collecting rake 4 then continues downward until it rises again carrying the debris from the intercepting plate 3. When the collecting rake 4 rises again and lifts the release plate 103, causing it to rotate, the debris that was previously intercepted by the release plate 103 is removed. 03. Debris intercepted and retained will slide into the storage box 111 as the release plate 103 rotates. This prevents debris from remaining on the surface of the release plate 103 for an extended period, avoiding debris accumulation that could obstruct the release plate 103's reset or interfere with its movement. Simultaneously, the rotation of the release plate 103 ensures that all debris enters the storage box 111, achieving centralized temporary storage and subsequent removal of debris. The upward tilt of the top of the interceptor plate 3 allows debris to remain on its surface when carried and intercepted by the water flow, thus preventing debris from being trapped. After accumulating on its surface, due to excessive accumulation or strong water flow impact, debris in the water flow may overflow the top of the interceptor plate 3, causing it to escape. The upward tilt angle of the top of the release plate 103 prevents the debris from slipping after being intercepted by the release plate 103 during the downward movement of the collecting rake 4 and its passage through multiple release troughs 104. This prevents excessive accumulation of debris from causing it to slip and ensures the stability of the release plate 103 in separating debris from the collecting rake 4. During the rotation of the release plate 103, its top end contacts the trigger plate 127. At this time, the trigger plate 127 is squeezed by the release plate 103, thereby pushing the trigger plate 127. Subsequently, the trigger plate 127 pushes the corresponding triangular plate 125, causing the triangular plate 125 to slide on the top of the storage frame 111. As the triangular plate 125 continues to slide, its top slope will lift the synchronizing rod 124, and the synchronizing rod 124 will drive multiple pressing rods 121 to move upward synchronously. At this time, the pressing plate 122 will also move upward along with the synchronizing rod 124, and the pressing spring 123 will be compressed synchronously. To provide a reverse reset driving force for the elastic potential energy storage of the compression spring 123, after the release plate 103 is reset under the action of the torsion spring 105, the debris on the release plate 103 will slide into the storage frame 111, and the elastic potential energy stored in the compression spring 123 will be released, thereby pushing the compression plate 122 to move downward quickly, applying a squeezing force to the debris that has fallen into the storage frame 111. The triangular plate 125 will slide backward as the compression spring 123 resets, and the synchronizing rod 124 will descend accordingly. The buckle plate 126 set at one end of the triangular plate 125 will restrict the reset position of the triangular plate 125. To prevent the triangular plate 125 from over-resetting and disengaging from the synchronous rod 124, the squeezing plate 122 compresses the debris, causing the moisture in the debris to gradually separate and be discharged through the drain hole 112, thereby reducing the moisture content of the debris. This step not only expands the storage space for debris and effectively compresses the volume of debris, but also reduces the subsequent cleaning load and improves the overall operating efficiency. When the storage box 111 is full of debris, the operator can pull the two fixed handles 117 to cause the fixed handles 117 to drive the corresponding fixed rods 116 to disengage from the adjustment hole 52, and then pull the storage box 111 to make the storage box... 111 slides along the adjusting frame 51 and adjusting groove 53 via the positioning plate 113 and positioning wheel 114 until the storage frame 111 is completely detached from the adjusting frame 51. Then, the debris in the storage frame 111 is poured into the designated cleaning area, completing the closed loop of a single filtering, collection, dehydration and transfer process. If it is necessary to continue collecting debris in the water, the empty storage frame 111 can be pushed back into the adjusting frame 51 along the adjusting groove 53 until the storage frame 111 reaches the preset position. Then, the fixing spring 118 will push the fixing rod 116 into the corresponding adjusting hole 52, thereby realizing the automatic locking and positioning of the storage frame 111. After the staff has completed the filtration of the water flow and needs to close the gate body 2, the storage frame 111 can be removed first in the manner described above. Then, the two uppermost adjustment handles 510 are pulled so that the adjustment handles 510 drive the locking rods 59 to disengage from the corresponding adjustment holes 52. Then, the corresponding auxiliary plates 54 are pushed upward so that the two uppermost auxiliary plates 54 and the adjustment wheel 57 slide upward along the adjustment frame 51 and the adjustment groove 53 until the two uppermost auxiliary plates 54 disengage from the top of the adjustment frame 51. Then, in the same manner described above, the two lower adjustment handles 510 are pulled in sequence so that the remaining locking rods 59 disengage from the corresponding adjustment holes 52, and all the auxiliary plates 54 slide upward along the adjustment frame 51 and the adjustment groove 53 in sequence and disengage. If it is necessary to adjust the tilt angle of the interceptor plate 3 so that it can intercept debris at different depths of the water flow, the two bottom adjustment handles 510 can be pulled at the same time. This will cause the two bottom adjustment handles 510 to drive the corresponding locking rods 59 to disengage from the adjustment holes 52. Then, the two bottom auxiliary plates 54 are pulled downward. At this time, the two first rotating plates 55 and the second rotating plate 56 rotate through their respective shafts at opposite ends, thereby changing the tilt angle of the two second rotating plates 56. Since the interceptor plate 3 is located on the opposite side of the two second rotating plates 56, the tilt angle of the interceptor plate 3 changes synchronously when the angle of the two second rotating plates 56 changes. When the staff confirms that the interceptor plate 3 has reached the preset tilt angle, the adjustment handles 510 are released. The locking rods 59 are automatically inserted into the corresponding adjustment holes 52 under the action of the locking springs 511, thereby achieving precise adjustment and reliable locking of the tilt angle of the interceptor plate 3. It should be noted that, regardless of the tilt angle of the interceptor plate 3, the water level must not exceed the upward angle at the top of the interceptor plate 3; otherwise, the water will overflow and damage the debris trapping function of the interceptor plate 3.
