Description

Technical Field

[0001] The invention relates to the technical field of river cleaning, and in particular to a cleaning device for the surface of a water conservancy river. Background Art

[0002] In the city's water conservancy rivers, there are inevitably a lot of floating garbage such as plastic bags, plastic bottles and plastic paper. This kind of garbage not only affects the quality of the river water, but also causes great harm to the surrounding ecology, causing harm to the life of the organisms in the water conservancy river after swallowing. When there is floating garbage on the surface of the water conservancy river, a cleaning device is needed to clean the floating garbage. During the movement of the ship, the garbage is gathered through the filter frame unfolded at the bow, and the gathered garbage is transported to the hull by the conveyor belt, thereby completing the treatment of the garbage in the water conservancy river.

[0003] At present, the cleaning device on the surface of the river cannot classify the size of the garbage during actual operation. When the filtering gap of the filtering equipment is small, although it can intercept most of the small and large garbage, the filtering equipment is prone to garbage blockage and needs to be cleaned frequently. Secondly, the blocked filtering equipment will increase the resistance of the hull, reduce the running speed of the hull, and affect the cleaning efficiency of the garbage on the river surface. When the filtering gap of the filtering equipment is large, although the probability of blockage will be reduced, small garbage cannot be cleaned, which will affect the cleaning effect of the device. Summary of the invention

[0004] The present invention provides a cleaning device for the surface of a water conservancy river channel, which is capable of filtering and processing small-volume impurities flowing out of a filter frame.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the cleaning device for the surface of a water conservancy river, the conveyor belt assembly and the filter frame installed on the conveying frame can be used on the water conservancy river through the hull, so as to facilitate the treatment of garbage floating on the surface of the water conservancy river. The filter frame can be rotated on the conveying frame to adjust the working deflection angle through the cooperation of the plug-in block, the connecting shaft and the rotating block. The filter gap formed by a plurality of equidistantly distributed filter rails fixed on the filter frame can filter large-volume impurities, and the phenomenon of garbage blockage can be avoided. The rotation amplitude of the filter frame on the conveying frame can be controlled through the cooperation of the first articulated block, the second articulated block and the servo hydraulic cylinder. It is convenient to filter and gather the garbage on the surface of the water conservancy river. The gathered garbage can be transported by the conveyor belt assembly during the movement of the hull, so as to facilitate the removal of garbage on the water surface. The transported garbage can be stored in the garbage storage bin for unified treatment. The installation rod fixed at the tail of the hull can be convenient for the installation of the trawl net, so that the hull can filter and treat small impurities flowing out of the filter frame during the movement. The size of the garbage can be distinguished during the garbage treatment process, which is convenient for the classification and treatment of garbage of different volumes, and can greatly reduce the risk of blockage of the device, thereby improving the efficiency of garbage cleaning on the surface of the water conservancy river.

[0018] 2. The cleaning device for the surface of a water conservancy river channel can drive the L-shaped plate to move vertically through the screw rod assembly installed in the first cavity, so as to realize the purpose of synchronous movement of the first interference rod and the first wedge-shaped block sliding in the rectangular block, so as to cause the first wedge-shaped block to interfere with the first interference block during the vertical movement, and can drive a plurality of cleaning rods installed on the cleaning seat to move vertically and slowly in the filter frame. The cleaning rod can dredge the garbage blocked between the filter railings during the movement, so as to improve the garbage gathering efficiency. When the third wedge-shaped block fixed on the first interference block interferes with the second interference block fixed on the filter frame, the purpose of shifting the position of the cleaning seat can be realized, so as to cause a plurality of cleaning rods to move in the gap of the filter railing, so as to realize the purpose of falling off part of the garbage on the cleaning rod, and facilitate the garbage entangled on the cleaning rod to clean itself, so as to reduce the influence of the resistance when the hull moves. When the wedge block collides with the second interference rod on the conveying frame, the purpose of pushing the knife holder to drive multiple cutters to move on the filter frame can be achieved, and the remaining garbage on the cleaning rod can be cut, so that the cut garbage can fall off the cleaning rod, thereby improving the garbage cleaning effect on the cleaning rod and further reducing the resistance influence when the hull moves. Through the cooperation of the interference plate and the inclined groove on the interference plate, the first interference rod is conveniently moved vertically to a certain height. After the cleaning rod completes the garbage cutting, the first interference rod can move into the inclined groove under the action of elastic force, prompting the first wedge block to release the resistance to the first interference block, so that the cleaning seat is affected by the elastic force of the fourth spring and moves downward quickly. Since the cleaning seat rises slowly and descends quickly, a speed difference can be formed, prompting the cleaning rod to automatically separate from debris, greatly reducing the resistance influence when the hull moves, thereby improving the cleaning efficiency of garbage on the surface of the water conservancy river.

[0019] 3. The cleaning device for the surface of a water conservancy river channel is convenient for slidingly connecting a plurality of observation rods through a plurality of hollow columns fixed on a cleaning seat. The two abutting cylinders rotatably connected at the ends of the cleaning rods can be engaged with the V-shaped blocks at the lower ends of the observation rods, so that the observation rods are convenient for position deflection when entangled with garbage, which can drive the abutting cylinders to conflict with the V-shaped blocks, and can cause the observation rods to telescope and move in the corresponding hollow columns, so that it is convenient to observe which cleaning rod is entangled with garbage. When it cannot be cleaned off, it can be cleaned manually, so that the device can operate normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1-Figure 9A cleaning device for the surface of a water conservancy river comprises a hull 2 ​​and a conveying frame 1 rotatably connected to the hull 2, a conveying belt assembly for conveying garbage is installed on the conveying frame 1, a garbage placement bin 3 is arranged on the hull 2, plug-in blocks 4 are fixed on both sides of the conveying frame 1, the plug-in block 4 is rotatably connected to a rotating block 6 through a connecting shaft 5, a filter frame 7 is fixed on the rotating block 6, and a plurality of equidistantly distributed filter rails 8 are fixed on the filter frame 7;

[0033] A first hinge block 9 is fixed on the filter frame 7 , a second hinge block 10 is fixed on the conveying frame 1 , a servo hydraulic cylinder 11 is hinged between the second hinge block 10 and the first hinge block 9 , and a mounting rod 12 for mounting a trawl net is fixed at the tail of the hull 2 ​​.

[0034] As an optional solution of the cleaning device for the surface of a water conservancy river channel of the present invention, the conveyor belt assembly includes two mounting frames 101, the two mounting frames 101 are fixed on the conveying frame 1, and a plurality of rotating rollers 102 are rotatably connected in the mounting frames 101 through bearings, and conveyor belts 103 are arranged in the two mounting frames 101, and both sides of the conveyor belts 103 are mounted on the plurality of rotating rollers 102.

[0035] As an optional solution of the cleaning device for the surface of a water conservancy river channel of the present invention, a plurality of equidistantly distributed V-shaped material retaining strips 14 are fixed on the surface of the conveyor belt 103, and a plurality of equidistantly distributed water filtering holes 15 are opened on the surface of the conveyor belt 103.

[0036] When cleaning the garbage on the surface of the water conservancy river channel, the hull 2 ​​drives the conveying frame 1 to move, and in the process of moving, the telescopic shaft of the servo hydraulic cylinder 11 hinged between the second hinge block 10 and the first hinge block 9 is contracted, and the two filter frames 7 are extended through the cooperation of the plug-in block 4, the connecting shaft 5 and the rotating block 6. As the hull 2 ​​continues to move on the water surface, the garbage is continuously gathered in the two filter frames 7, and the filter gap formed by a number of equidistantly distributed filter rails 8 fixed on the filter frames 7 can filter large-volume impurities, and then the servo hydraulic cylinder 11 is used to control the rotation amplitude of the two filter frames 7 on the conveying frame 1, so that the garbage on the surface of the water conservancy river channel can be gathered onto the conveyor belt 103 when the hull 2 ​​moves. During the movement of the hull 2, a number of filter rails 8 in the two installation frames 101 are used to control the rotation amplitude of the two filter frames 7 on the conveying frame 1. The rotating rollers 102 drive the conveyor belt 103 to run, and the garbage gathered on the water surface can be scooped up through the multiple V-shaped blocking strips 14 fixed on the conveyor belt 103. The water attached to the garbage can be filtered and separated during the transportation of the conveyor belt 103 through the multiple equidistantly distributed water filtering holes 15 on the surface of the conveyor belt 103, thereby reducing the moisture in the garbage storage bin 3 and increasing the garbage storage capacity. The installation rod 12 fixed at the tail of the hull 2 ​​can facilitate the installation of the trawl net, so that the hull 2 ​​can filter and process small-volume impurities flowing out of the filter frame 7 during the movement. The size of the garbage can be distinguished during the garbage treatment process, which is convenient for classifying and processing garbage of different volumes, and can greatly reduce the risk of the device being blocked, thereby improving the efficiency of garbage cleaning on the surface of the water conservancy river.

[0037] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 9 A first cavity 16 is provided on the filter frame 7, and a resistance plate 17 and a screw assembly are respectively arranged in the first cavity 16. The resistance plate 17 is fixedly connected to the filter frame 7 through a mounting column 18, and an inclined groove 22 is provided on the resistance plate 17. The screw assembly is installed on the filter frame 7, and an L-shaped plate 19 is installed on the screw assembly. A first resistance rod 20 is slidably connected to the L-shaped plate 19, and the first resistance rod 20 is elastically connected to the L-shaped plate 19 through a second spring 21. One end of the first resistance rod 20 is in resistance to the resistance plate 17, and the other side of the first resistance rod 20 is slidably connected to the filter frame 7.

[0038] A rectangular block 23 is fixed to the end of the first abutting rod 20 , a first wedge block 24 is slidably connected inside the rectangular block 23 , and the rectangular block 23 is elastically connected to the first wedge block 24 via a third spring 26 .

[0039] A cleaning seat 25 is provided on the filter frame 7, and the cleaning seat 25 is elastically connected to the filter frame 7 through a fourth spring 28, and a plurality of equidistantly distributed cleaning rods 251 are rotatably connected to the cleaning seat 25, and the cleaning rods 251 are elastically connected to the cleaning seat 25 through a torsion spring 252, and a first resistance block 27 is fixed on the cleaning seat 25, and the first resistance block 27 is opposite to the first wedge block 24, and a guide plate 37 is fixed on the cleaning seat 25, and the guide plate 37 is attached to the surface of the filter railing 8.

[0040] A second abutment block 35 is fixed on the filter frame 7 , and a third wedge block 36 is fixed on the first abutment block 27 . The third wedge block 36 is opposite to the second abutment block 35 .

[0041] A second cavity 29 is opened on the filter frame 7, and a knife holder 30 is arranged in the second cavity 29. The knife holder 30 is elastically connected to the filter frame 7 through a first spring 31. A plurality of equidistantly distributed cutters 32 are fixed below the knife holder 30, and a second wedge block 33 is fixed above the knife holder 30. A second resistance rod 34 is fixed on the conveying frame 1.

[0042] The screw assembly includes a screw 71, both ends of which are rotatably connected to the filter frame 7 through bearings, and a moving block 72 is threadedly connected to the screw 71, an L-shaped plate 19 is fixed to the moving block 72, a guide bar 73 is fixed to the filter frame 7, the moving block 72 is slidably connected to the guide bar 73, a servo motor 74 is fixed to the filter frame 7, and the motor shaft of the servo motor 74 is transmission-connected to one end of the screw 71 through a coupling.

[0043] As the filter frame 7 collects garbage, the garbage will be entangled on the filter railing 8. The garbage entangled on the filter railing 8 will make it more difficult for the filter frame 7 to rotate. Secondly, it will increase the resistance of the hull 2 ​​during movement, affecting the speed of the hull 2 ​​and the efficiency of garbage disposal. Therefore, during the garbage disposal process, it is necessary to remove the garbage entangled on the filter railing 8. Figure 4-Figure 8, the servo motor 74 installed on the filter frame 7 drives the screw rod 71 to rotate, so that the screw rod 71 drives the moving block 72 to move vertically and horizontally on the guide bar 73. At the same time, the first contact rod 20 slidably connected to the L-shaped plate 19 fixed on the moving block 72 is subjected to the elastic force of the second spring 21, so that one end of the first contact rod 20 contacts the contact plate 17, and the rectangular block 23 fixed at the other end of the first contact rod 20 is under the elastic force of the third spring 26, so that the first wedge block 24 moves toward one end of the rectangular block 23, so that it is located below the first contact block 27. When the moving block 72 moves vertically, the first wedge block 24 contacts the bottom of the first contact block 27, thereby driving the several cleaning rods 251 on the cleaning seat 25 to move vertically slowly in the filter frame 7. At the same time, the fourth spring 28 accumulates force. During the movement of the several cleaning rods 251, the garbage blocked between the filter rails 8 can be dredged and the garbage can be moved to the top of the filter rails 8.

[0044] At this time, the third wedge block 36 fixed on the first conflicting block 27 conflicts with the second conflicting block 35 fixed on the filter frame 7, so that the cleaning seat 25 and the plurality of cleaning rods 251 installed on the cleaning seat 25 move, prompting the cleaning rod 251 to shrink in the gap of the filter railing 8, so as to achieve the purpose of falling off some garbage on the cleaning rod 251, facilitating the cleaning of the cleaning rod 251, reducing the amount of garbage on the cleaning rod 251, and reducing the resistance effect on the movement of the hull 2. At the same time, when the filter frame 7 deflects the garbage gathering, it can prompt the second conflicting rod 34 on the conveying frame 1 to conflict with the second wedge block 33 on the knife holder 30, so that the second wedge block 33 moves downward, facilitating the extension of multiple cutters 32 from the second cavity 29 of the filter frame 7, which can The remaining entangled garbage on the vertically moving cleaning rod 251 is cut and processed. When the first resistance rod 20 moves vertically into the inclined groove 22 opened on the resistance plate 17, the second spring 21 releases the elastic force to drive the first resistance rod 20 to resist the inner side of the inclined groove 22, causing the horizontal position of the first wedge block 24 to change, thereby releasing the resistance to the first resistance block 27. The fourth spring 28 releases the elastic force to drive the cleaning seat 25 to move downward quickly. Since the cleaning seat 25 rises slowly and descends quickly, a speed difference can be formed, which causes the cleaning rod 251 to automatically separate from the debris, greatly reducing the resistance effect of the hull 2 ​​when moving, thereby improving the cleaning efficiency of the garbage on the surface of the water conservancy river channel, and facilitating the transportation of the cut and separated garbage to the garbage storage bin 3 through the conveyor belt 103 for storage.

[0045] The guide plate 37 fixed on the cleaning seat 25 can limit the moving position of the cleaning seat 25, thereby improving the stability of the vertical and horizontal movements of the cleaning seat 25 and reducing movement deviation.

[0046] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 9 A plurality of hollow columns 38 are fixed on the cleaning seat 25, an observation rod 39 is slidably connected inside the hollow column 38, a V-shaped block 40 is connected to the lower end of the observation rod 39, and the end of the cleaning rod 251 is rotatably connected to two abutting cylinders 13.

[0047] If the cleaning rod 251 is entangled with garbage that is difficult to clean, the garbage entangled at the filter railing 8 cannot be cleaned normally, and the filter frame 7 is blocked, which will reduce the efficiency of the device in treating garbage on the water conservancy river surface. Manual cleaning is required. Since the cleaning rod 251 is mainly underwater when working, it is impossible to observe which cleaning rod 251 is entangled with garbage with the naked eye. It is necessary to set a corresponding observation rod 39 on one side of the cleaning rod 251 to observe the entanglement of the cleaning rod with garbage. Figure 5-Figure 9 The two abutting cylinders 13 rotatably connected at the end of the cleaning rod 251 can be engaged with the V-shaped block 40 at the lower end of the observation rod 39. When the observation rod 39 is entangled with garbage, the observation rod 39 will be deflected in the horizontal direction. The torsion spring 252 accumulates force, which can drive the abutting cylinder 13 to come into conflict with one side surface of the V-shaped block 40, and can prompt the observation rod 39 to rise and move in the corresponding hollow column 38. By checking the position height of the observation rod 39, it is convenient to observe which cleaning rod 251 is entangled. If it cannot be cleaned off, it can be cleaned manually to facilitate the normal operation of the device.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
