When the floating body rises, it will pull the extension rod downward through the pulling rope of the rope and pulley assembly, causing the V-shaped flipping cleaning frame to flip upward, lift the debris, and separate the debris along the V-shaped flipping cleaning frame to the outside of the water channel, automatically cleaning the floating debris.

Description

Technical Field

[0001] The present invention relates to the technical field of canal debris cleaning, and particularly to an adaptive cleaning device for floating debris in canals. Background Art

[0002] When there is relatively abundant water resources on the land surface, a large number of canals are built to divert the water in rivers for farmland irrigation. When irrigating farmland, it is necessary to use the canals dug on the ground to conduct a certain diversion of the water flow and introduce the water flow into the farmland. Canals are artificially dug waterways, which are divided into main canals and branch canals. Generally, main canals and branch canals are built with stone or cement. The built canals are generally laid outdoors, and the diverted water usually contains certain debris, such as weeds, tree trunks, and fallen leaves, etc. These debris enter the farmland along with the water flow, affecting the growth of crops. At the same time, when there is a large amount of debris, long-term accumulation will cause the canal flow to become smaller or even blocked, reducing the smoothness of the canal and affecting the normal use of the canal. Therefore, it is necessary to clean the debris in the water. When using manual tools to clean the debris in the canal, it is not only time-consuming and laborious with low efficiency, but also the cleaning effect is poor. When using existing cleaning equipment to clean the debris in the canal, the cleaning effect is poor and it is inconvenient to use, and there are still certain defects. For example, the Chinese patent publication document with the publication number "CN113957864A" discloses a debris cleaning device in an irrigation canal for water conservancy projects. The debris cleaning device in the irrigation canal for water conservancy projects includes: two brackets, and a first filter screen for blocking debris in the canal is fixedly connected between the brackets; a cleaning component, the cleaning component is fixedly connected between the two brackets, and the cleaning component is used for cleaning the floating objects on the upper layer in the canal; the lifting component is arranged in the brackets, and the lifting component is used to adjust the cleaning component to move up and down along with the water level line. In the present invention, the driving motor is turned on to drive the reciprocating screw rod to rotate, so that the moving block can make a reciprocating movement when the reciprocating screw rod rotates. Therefore, the cleaning rod fixedly connected to the connecting rod through the mounting plate also makes a reciprocating movement in the water, pushing the floating objects in the water to both sides of the canal to achieve the cleaning effect. Although the debris can be cleaned, it relies on the screw rod to control the descent of the cleaning rod and the motor to control the reciprocating movement of the cleaning rod. A power mechanism must be set up to achieve the cleaning of the debris. At the same time, the debris pushed by the cleaning rod each time is limited, and the cleaning is not thorough. The cleaning component needs to make multiple reciprocating movements to push the debris blocking the impurities into the collection cylinder. The cleaning component is always in an operating state, and its service life will be reduced after long-term operation. Moreover, this device only pushes the debris into the collection cylinder, and still requires manual removal of the debris in the collection cylinder, increasing the cleaning cost. The treatment effect on the debris is poor, and it cannot achieve adaptive cleaning of the debris, and there are certain defects. Therefore, it is necessary to develop a self-cleaning device for floating debris in canals. Summary of the Invention

[0003] In view of the above-mentioned defects and problems, the present invention provides a floating debris cleaning device for a water channel, the purpose of which is to pull the floating debris through a debris net. When the debris net blocks a lot of debris and causes the channel to be blocked, causing the water level to rise, it will simultaneously drive the floating body, and the floating body always maintains the same water level line as the water surface in the water channel. When the floating body rises, the pulley of the rope pulley assembly will pull the extension rod downward, causing the V-shaped flip cleaning frame to flip upward, lift up the debris, and separate the debris along the V-shaped flip cleaning frame to the outside of the water channel, so as to automatically clean the floating debris.

[0004] The solution adopted by the present invention to solve its technical problems is: a floating debris cleaning device for a water channel, including a debris blocking net arranged in the water channel, and also including a V-shaped flip cleaning frame, a float assembly and a pulley assembly, and a hinged seat and a matching seat are respectively provided on both sides of the water channel, and the V-shaped flip cleaning frame is arranged on the front side of the debris blocking net, and the V-shaped flip cleaning frame includes a left plate and a right plate hinged in a V shape, the free end of the right plate is hinged in the hinged seat, and an extension rod is fixed, and the free end of the left plate is slidably sleeved in the matching seat; the float assembly includes a vertical cavity arranged on the side of the water channel, the vertical cavity is connected with the water channel through a through hole, a float is provided in the vertical cavity, and the float is fixedly connected to the extension rod through the pulley assembly.

[0005] Furthermore, an articulated shaft is provided in the articulated seat, and the articulated shaft is rotatably sleeved in the articulated seat through a swivel sleeve, the free end of the right plate is fixedly connected to the articulated shaft, and the extension rod is fixed on the articulated shaft in the same direction as the right plate; a rotating shaft is rotatably sleeved in the mating seat, and a flat hole corresponding to the left plate is opened through the rotating shaft, and the left plate is slidably sleeved in the flat hole.

[0006] Furthermore, the pulley assembly includes a pulley frame 1 arranged at the bottom of the vertical cavity, and a pulley frame 2 and a pulley frame 3 are arranged on the side of the channel. The bottom of the floating body is fixedly connected to a pull rope, and the pull rope is sequentially mounted on the pulley frame 1, the pulley frame 2 and the pulley frame 3, and is fixedly connected to the extension rod. When the floating body rises, the extension rod will be pulled downward by the pull rope, so that the V-shaped flip cleaning frame will flip upward.

[0007] Furthermore, a movable cover plate is provided on the top of the vertical cavity.

[0008] Furthermore, it also includes an energy storage elastic mechanism arranged between the rope wheel assembly and the right plate.

[0009] Furthermore, an anti-fixing switching mechanism is also provided on the V-shaped flip cleaning frame.

[0010] The beneficial effects of the present invention are as follows: the present invention has a unique structure and an ingenious design. A debris net is arranged in the water channel, and a V-shaped flip cleaning frame is arranged in front of the debris net. The right plate of the V-shaped flip cleaning frame is hinged to the side of the water channel through a hinge seat, and the left plate of the V-shaped flip cleaning frame is sleeved on the other side of the water channel through a matching seat. The floating body in the vertical cavity is connected to the extension rod of the right plate through a rope pulley assembly. When the debris net blocks more debris and causes the channel to be blocked, the floating body will be driven synchronously when the water level rises. The floating body is always kept at the same water level line with the water surface in the water channel. Using buoyancy as the power, when the floating body rises, it drives the pull rope to move upward, and simultaneously pulls the extension rod downward through the pulley assembly, so that the hinge shaft rotates in the hinge seat, controlling the right plate to flip upward. When the right plate flips upward, it drives the left plate to flip together. The left plate cooperates with the flipping of the right plate through the rotating shaft, so that the overall V-shaped flip cleaning frame flips upward. When the V-shaped flip cleaning frame flips online, it will directly lift up the floating objects intercepted by the debris net, and separate the debris along the V-shaped flip cleaning frame to the outside of the canal, thereby realizing automatic cleaning of floating debris.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1: When using manual handheld tools to clean the debris in the canal, it is not only time-consuming and labor-intensive, but also inefficient and has a poor cleaning effect. When using existing cleaning equipment to clean the debris in the canal, a power mechanism must be set up to achieve the cleaning of the debris. At the same time, the amount of debris pushed by the cleaning rod each time is limited, and the cleaning is not thorough. The cleaning component needs to reciprocate multiple times, and the cleaning component is always in operation. After long-term operation, its service life will be reduced, and the debris processing effect is poor, and adaptive debris cleaning cannot be achieved.

[0020] In view of the above problems, this embodiment provides a device for cleaning floating debris in a water channel, such as Figure 1-3 As shown, a debris-blocking net 2 is fixedly installed in the water channel 1, and a V-shaped flip cleaning frame 3 is provided on the front side of the debris-blocking net 2. The V-shaped flip cleaning frame 3 includes a left plate 31 and a right plate 32 hinged in a V shape. A hinge seat 4 and a matching seat 5 corresponding to the left plate 31 and the right plate 32 are fixedly installed on both sides of the water channel 1 respectively. A hinge shaft 41 is provided in the hinge seat 4, and the hinge shaft 41 is rotatably mounted in the hinge seat 4 through a rotating sleeve 83. The free end of the right plate 32 is fixedly connected to the hinge shaft 41, and an extension rod 33 is provided at the free end of the right plate 32 in the same direction. The extension rod 33 is fixed on the hinge shaft 41 in the same direction as the right plate 32, and the right plate 32 can rotate around the hinge shaft 41.

[0021] A rotating shaft 51 is rotatably mounted in the matching seat 5. A flat hole corresponding to the left plate 31 is penetrated through the rotating shaft 51. The left plate 31 is slidably mounted in the flat hole of the rotating shaft 51. The left plate 31 can move with the right plate 32 through the rotating shaft 51, and can also slide in the flat hole of the rotating shaft 51.

[0022] A vertical cavity 62 is vertically opened on the right side of the canal, and a movable cover can be set on the top of the vertical cavity 62. The vertical cavity 62 is connected with the canal 1 through a through hole. The water in the canal 1 enters the vertical cavity 62, and a float 61 is set in the vertical cavity 62. Since the canal 1 is connected with the vertical cavity 62, the float 61 will always maintain the same horizontal plane with the water level in the canal 1. When the water level in the canal 1 changes, the float 61 will move synchronously with the water level. At the same time, considering the buoyancy of the float, the vertical cavity can be set to a rectangle, and the float is also set to a rectangle to increase the contact area between the float and the water surface and increase the buoyancy of the float.

[0023] The sheave assembly 7 includes a sheave frame 71 arranged at the bottom of the vertical cavity. The sheave frame 71 is located below the middle of the floating body 61. A sheave frame 2 72 and a sheave frame 3 73 are arranged on the right side of the vertical cavity. The bottoms of the sheave frames 2 72 and 73 are fixed to the side of the canal 1. Sheave frames 1 71, 72 and 73 are all equipped with sheaves. A pull rope 74 is fixedly connected to the bottom of the floating body 61. The pull rope 74 is mounted in the sheave frame 1 71 and led out and mounted in the sheave frame 3 73. The pull rope mounted in the sheave frame 73 is led out and mounted in the sheave frame 2 72. The pull rope in the sheave frame 2 72 is fixedly connected to the extension rod 33. When the floating body 61 rises, the right plate 32 can be pulled downward by the pull rope 74.

[0024] The floating debris is pulled by the debris intercepting net 2. When the debris intercepting net 2 intercepts a lot of debris and causes the channel to be blocked, causing the water level to rise, the floating body 61 will be driven synchronously. At the same time, the floating body 61 is always kept at the same water level line as the water surface in the water channel 1. The buoyancy of the floating body 61 is used as the power. When the floating body 61 rises, it drives the pull rope 74 to move upward, and simultaneously pulls the extension rod 33 downward through the pull rope 74 of the rope pulley assembly 7, so that the hinge shaft 41 rotates in the hinge seat 4, controls the right plate 32 to flip upward, and the right plate 32 is turned upward. When flipping upward, the left plate 31 is driven to flip together. The left plate 31 cooperates with the flipping of the right plate 32 through the rotating shaft 51, so that the whole V-shaped flip cleaning frame 3 flips upward. When the V-shaped flip cleaning frame 3 flips online, it will directly lift up the floating objects intercepted by the interception net 1, and separate the debris along the V-shaped flip cleaning frame 3 to the outside of the canal 1, so as to realize automatic cleaning of the floating debris. After the debris is cleaned out, it will no longer cause blockage to the canal. The water level drops, the float drops accordingly, and the V-shaped flip cleaning frame 3 is reset to its initial state.

[0025] Preferably, the V-shaped flip cleaning frame lifts up the floating objects and separates and cleans them out when flipping upwards. However, considering that some floating objects may not be separated and cleaned out by the V-shaped flip cleaning frame and remain on the V-shaped flip cleaning frame, an energy storage elastic mechanism 8 is provided. Figure 1 and Figure 5 As shown, the pull rope 74 is connected to the extension rod 33 through the tension spring 81.

[0026] A jack is formed through the rotating sleeve 83, and a guide sleeve 86 is fixed to the outside of the jack. A clamping hole 84 corresponding to the jack is formed in the hinge shaft 41. A spring seat 88 is fixed to the outer end of the guide sleeve 86. An elastic pin 85 is slidably sleeved in the guide sleeve 86. The outer end of the elastic pin 85 is constrained in the spring seat 88 by a baffle. A compression spring 87 is arranged between the outer end of the elastic pin 85 and the spring seat 88. One end of the compression spring 87 is fixed to the spring seat 88, and the other end is fixed to the baffle at the outer end of the elastic pin 85. An auxiliary rope 82 in a slack state is arranged between the pull rope 74 and the spring seat 88. One end of the auxiliary rope 82 enters the spring seat 88 and is fixedly connected to the baffle at the outer end of the elastic pin 85, and the other end is fixedly connected to the pull rope 81. The elastic pin 85 can be pressed inward by the compression spring 87 and is constrained in the clamping hole 84 through the jack, locking the hinge shaft 41 in the hinge seat 4.

[0027] In the initial state, the elastic pin 85 can be pressed inward by the compression spring 87 and enter the clamping hole 84 to lock the hinge shaft 41 in the hinge seat 4. When the floating body 61 moves upward, driving the pull rope 74 to move upward, and simultaneously pulling the extension rod 33 downward through the pull rope 74 of the rope pulley assembly, since the hinge shaft 41 is locked by the elastic pin 85, the pulling force will be directly applied to the tension spring 81. The tension spring 81 is pulled and unfolded to store energy. During the process of the tension spring 81 being gradually stretched, the pull rope 74 will also pull the auxiliary rope 82, making the originally slack auxiliary rope 82 gradually tightened. When the auxiliary rope 82 is pulled and tightened to a certain extent, it will directly pull the elastic pin 85 out of the clamping hole 84 of the hinge shaft 41, causing the elastic pin 85 to disengage from the clamping hole 84. The elastic pin 85 moves into the guide sleeve 86 and no longer restricts the clamping hole 84. The tension spring 81 releases the stored pulling force, and the hinge shaft 41 rotates directly in the rotating sleeve 83. The clamping hole 84 of the hinge shaft 41 is misaligned with the jack, and the inner end of the elastic pin 85 will fit against the outer peripheral side wall of the hinge shaft 41. The right plate 32 will be directly bounced upward, and then the overall V-shaped flipping cleaning frame 3 will be bounced upward, releasing the stored energy and realizing an upward flipping and bouncing motion process. While pushing the intercepted floating objects upward, a elastic force is applied to bounce the floating debris that may remain on the V-shaped flipping cleaning frame and clean it out of the water channel along the V-shaped flipping cleaning frame;

[0028] After the sundries are cleared out and no longer block the water channel, causing the water level to drop. When the floating body 61 moves downward accordingly, the floating body 61 no longer applies a pulling force to the extension rod through the pull rope. The hinge shaft rotates in the rotating sleeve. Since the compression spring applies an inward pressing force to the elastic pin, when the clamping hole of the hinge shaft is aligned with the jack, the elastic pin will directly enter the clamping hole to restrict the hinge shaft.

[0029] Preferably, when cleaning the sundries that may be retained on the V-shaped flipping cleaning rack by the energy storage and bouncing method of the V-shaped flipping cleaning rack, there may still be some sundries that are not cleaned and remain on the V-shaped flipping cleaning rack. Therefore, an anti-fixed switching mechanism 9 is additionally provided. As Figure 6 shown, a counterweight 95 is fixed on the left plate 31. The right plate 32 is divided into two hinged sections by a pin shaft 94. An auxiliary rod 91 is fixed on the side of the right plate 32. The auxiliary rod 91 is divided into two sections. Stopping platforms 93 are respectively fixed at the front and rear ends of the auxiliary rod 91. A C-shaped sliding sleeve 92 is slidably sleeved on the auxiliary rod 91. The stopping platform at the front end of the auxiliary rod 91 is located on the front side of the pin shaft 94. An anti-rotation baffle 96 is provided at the hinge joint of the left plate and the right plate to prevent the front section of the right plate 32 from over-flipping.

[0030] In the initial state, the C-shaped sliding sleeve 92 is limited to the position of the pin shaft 94 by the stopping platform 93 under its own weight. The C-shaped sliding sleeve 92 can restrain the front and rear sections of the right plate 32. When the V-shaped flipping cleaning rack flips upward, the C-shaped sliding sleeve will slide backward under its own weight and no longer restrain the front and rear sections of the right plate 32. Under the action of the counterweight 95, the front section of the right plate follows the left plate to rotate in cooperation, and the front section of the right plate is constrained on the left plate through the anti-rotation baffle 96 to prevent the front section of the right plate from flipping downward, realizing the length switching of the left plate and the right plate, changing the jacking position of the V-shaped flipping cleaning rack, and further jacking up some of the sundries remaining on the V-shaped flipping cleaning rack, so that they are separated and cleaned along the V-shaped flipping cleaning rack to the outside of the water channel.

[0031] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
