Description

Technical Field

[0001] This invention relates to the field of rotary cleaning machine technology, and particularly to a large-scale rotary cleaning machine with a suspended truss structure. Background Technology

[0002] Currently, rotary screen cleaners are widely used in various water conservancy projects. They use a rotating rake device to clean the entire screen, solving the problem of dirt clogging the screen and removing impurities from the water, thus ensuring the safe and reliable operation of the unit.

[0003] Chinese invention patent CN110318374A discloses a mobile rotary bar screen cleaner for pump stations, belonging to the technical field of bar screen cleaning equipment during power station or pump station operation. It consists of a chain rake mechanism, a rotating mechanism, a moving mechanism, a hydraulic station, and a counterweight. The moving mechanism is installed on the bar screen bridge, the rotating mechanism is mounted on top of the moving mechanism, the chain rake mechanism is mounted on top of the rotating mechanism, and the hydraulic station and counterweight are mounted on one side of the moving mechanism. This invention has the lateral movement function of a mobile rake-type bar screen cleaner and the rotary cleaning function of a rotary bar screen cleaner, making installation and maintenance convenient. Only one bar screen cleaner is needed for the entire pump station to complete the cleaning work, which not only improves the efficiency of bar screen cleaning but also greatly reduces the cost of the cleaning project, saving engineering costs and maintenance expenses. It solves the problems of slow cleaning speed and low efficiency of existing mobile rake-type bar screen cleaners, the inability of rotary bar screen cleaners to move laterally, and the need for multiple rotary bar screen cleaners to be placed on the bar screen bridge of the entire pump station.

[0004] The above-mentioned device cleans impurities in the water using rake teeth. However, in actual use, when the rake teeth are loaded with a large amount of impurities, it will affect the stability of the rake teeth themselves. In addition, when the rake teeth enter the water surface, they will bring debris on the water surface into the water, which will increase the load on the chain when it rotates. In summary, the above-mentioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a large-scale suspended truss structure rotary cleaning machine to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a large-scale suspended truss structure rotary cleaning machine to solve the problem mentioned in the background art that the existing device cleans impurities in the water by rake teeth. However, in actual use, when the rake teeth are loaded with a lot of impurities, it will have a certain impact on the stability of the rake teeth themselves. In addition, when the rake teeth enter the water surface, they will bring the debris on the water surface into the water, thereby increasing the load on the chain when it rotates.

[0007] Based on the above ideas, the present invention provides the following technical solution: a large suspended truss structure rotary cleaning machine, including two chains arranged opposite to each other and a material trough arranged between the two chains, a support bar fixedly connected to one side of the bottom of the material trough, a plurality of support plates hinged to the bottom end of the material trough, an installation plate fixedly arranged between the two chains, and the material trough slidably arranged on the outside of the installation plate.

A slider is fixedly connected to the side of the material trough near the mounting plate. A guide shaft is provided on the mounting plate. The guide shaft passes through the slider and is slidably connected to it. A pressure block is fixedly sleeved on the outer bottom end of the guide shaft. When the slider moves downward relative to the guide shaft, causing the pressure block to rotate, the pressure block drives the snap-fit ​​assembly to slide outward relative to the support bar through the drive assembly. When the snap-fit ​​assembly moves outward and is misaligned with the corresponding support plate, the support plate can rotate downward relative to the material trough.

[0009] As a further aspect of the present invention: the snap-fit ​​assembly includes a limiting rod that slides with the support bar, and multiple sets of snap-fit ​​blocks are elastically connected to the side of the limiting rod near the support plate. The bottom of each snap-fit ​​block is set as a first inclined surface, and the number of snap-fit ​​blocks in each set is at least two. The distance that the multiple snap-fit ​​blocks in each set extend toward the support plate gradually decreases.

[0010] As a further aspect of the present invention: the driving assembly includes a slide rod, which is fixedly connected to a limiting rod. A sliding sleeve is fixedly connected to the bottom of the material trough. The slide rod passes through the sliding sleeve and slides with it. A limiting spring is sleeved on the outside of the slide rod. The two ends of the limiting spring are fixedly connected to the sliding sleeve and the limiting rod, respectively. A through groove is provided on the mounting plate, and an opening is provided on the side of the through groove near the material trough. The slider passes through the opening and extends into the through groove. A connecting plate is slidably provided at the bottom of the through groove. The end of the slide rod away from the limiting rod extends into the through groove and is fixedly connected to the connecting plate. A floating plate is provided between the pressure block and the connecting plate.

[0011] As a further embodiment of the present invention: a spiral limiting groove is provided on the outer peripheral surface of the guide shaft, a through hole is provided on the slider, the guide shaft passes through the through hole and slides with it, and a limiting block that slides with the limiting groove is fixedly connected to the inner wall of the through hole.

[0012] As a further aspect of the present invention: a partition is fixedly connected inside the through groove, the guide shaft passes through the partition and is rotatably connected to it, a support spring is sleeved on the outside of the guide shaft, and the support spring is disposed between the slider and the partition.

[0013] As a further aspect of the present invention: a plurality of sleeve rods are fixedly connected to the bottom end face of the mounting plate, and the sleeve rods correspond one-to-one with the support plate. A top rod is elastically connected to the end of the sleeve rod away from the mounting plate. Both the sleeve rod and the top rod are set in an arc shape, and the end of the top rod away from the sleeve rod is in contact with the support plate.

[0014] As a further aspect of the present invention, the support plate is provided with uniformly distributed sieve holes.

[0015] As a further aspect of the present invention: a fixing frame is provided on the outer side of the chain, and a mounting groove for accommodating the chain is provided on the side of the fixing frame near the chain, and sprockets are provided at both ends of the fixing frame, and the chain is sleeved between the two sprockets.

[0016] As a further aspect of the present invention: the top and bottom ends of the through groove are fixedly connected to cover plates, and the guide shaft is rotatably disposed between the two cover plates.

[0017] A sliding groove is provided on the top surface of the cover plate at the bottom of the channel. A sleeve is slidably installed in the sliding groove. A fixed rod is elastically connected to the top of the sleeve. The float plate is fixedly connected to the top of the fixed rod. Both sides of the top of the float plate are provided as second inclined surfaces.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This device, through the cooperation of the set drive component and the snap-fit ​​component, ensures that the support plate is in a vertical state during the process of the material trough entering the water, thus avoiding the introduction of garbage into the water. It can also avoid the chain from increasing the additional load when rotating. Furthermore, the support plates at the bottom of the material trough can be distributed according to the degree of garbage accumulation on the water surface. When there is a lot of garbage, the support plates are distributed more sparsely, which avoids the material trough being loaded with a large amount of garbage at one time. This is conducive to the uniform distribution of garbage to each material trough and can protect it. Attached Figure Description

[0035] like Figure 1-3 As shown, a large suspended truss structure rotary cleaning machine includes two chains 7 arranged opposite each other, with a trough 4 for cleaning impurities disposed between the two chains 7. The specific shape of the trough 4 is as follows. Figure 2 As shown, specifically, the feed trough 4 is U-shaped in general. A support bar 35 is fixedly connected to one side of the bottom of the feed trough 4. Multiple support plates 6 are evenly distributed at the bottom of the feed trough 4. Screen holes are evenly opened on the support plates 6 so that impurities can be retained at the bottom of the support plates 6, while water can be discharged through the screen holes.

[0036] Furthermore, an installation plate 8 is fixedly installed between the two chains 7, while the material trough 4 is slidably installed on the outside of the installation plate 8. In actual use, the entire device is placed at the grid of the water inlet. The rotation of the chain 7 can synchronously drive the installation plate 8 and the material trough 4 to rotate. When the material trough 4 on the right side of the chain 7 moves out of the water surface from bottom to top, the material trough 4 can scoop up the debris on the water surface, thereby cleaning the water surface. Afterwards, as the water flows, the debris on the water surface will re-gather in front of the grid. The continuously rotating material trough 4 can continuously clean the dirt on the water surface.

[0037] However, in actual use, when there is a lot of debris in front of the grid, the material trough 4 in front will be loaded with more debris, which makes the loading distribution of multiple material troughs 4 uneven. The material trough 4 loaded with more debris will bear greater pressure, which will easily affect the stability of its own structure. In addition, when the material trough 4 on the left side of the chain 7 enters the water surface, it will bring the debris on the water surface into the water, which will increase the load when the chain 7 rotates. Based on the above problems, the support plate 6 in this solution is hinged to the material trough 4 during installation. Specifically, the end of the support plate 6 near the chain 7 is fixedly connected to the hinge block 22, and multiple bases 23 are fixedly connected to the inner side of the material trough 4. Two adjacent bases 23 form a group and are distributed on both sides of the hinge block 22. The outer side of the hinge block 22 is fixedly connected to the hinge shaft, and the hinge shaft is rotatably connected to the base 23.

[0038] The bottom of the support bar 35 is provided with a snap-fit ​​assembly that cooperates with the support plate 6. A drive assembly is provided on the side of the snap-fit ​​assembly near the mounting plate 8. A slider 26 is fixedly connected to the side of the material trough 4 near the mounting plate 8. A guide shaft 20 is provided on the mounting plate 8. The guide shaft 20 passes through the slider 26 and is slidably connected to it. A pressure block 21 is fixedly sleeved on the outer bottom end of the guide shaft 20. The pressure block 21 is eccentrically set with the guide shaft 20. When the slider 26 moves downward relative to the guide shaft 20, it can drive the guide shaft 20 and the pressure block 21 to rotate. The pressure block 21 drives the drive assembly. The pressure of the component can cause the snap-fit ​​component to slide outward relative to the support bar 35. When the snap-fit ​​component moves outward and is offset from the corresponding support plate 6, the support plate 6 rotates downward relative to the trough 4, making the support plates 6 at the bottom of the trough 4 more sparsely arranged, which avoids the trough 4 from being loaded with too much garbage and helps to protect the trough 4. Furthermore, when the trough 4 is flipped to the left side of the chain 7, the support plate 6 rotates to a vertical position relative to the trough 4, which prevents impurities on the water surface from being brought into the water during the process of the trough 4 entering the water, and can avoid increasing the load on the chain 7 during operation.

[0039] like Figure 2-6As shown in Figures 8-13, the aforementioned snap-fit ​​assembly includes a limiting rod 13 that slides with the support bar 35. The limiting rod 13 is elastically connected to a plurality of snap-fit ​​blocks 14 on the side near the support plate 6. The bottom of each snap-fit ​​block 14 is configured as a first inclined surface 24. Specifically, the number of snap-fit ​​blocks 14 in each group is set to multiple, preferably two. The distance that the multiple snap-fit ​​blocks 14 in each group extend toward the support plate 6 gradually decreases. When the limiting rod 13 drives the snap-fit ​​blocks 14 to move away from the support plate 6, a portion of the support plate 6 will disengage from the snap-fit ​​blocks 14, thereby allowing this portion of the support plate 6 to rotate downward relative to the material trough 4.

[0040] The drive assembly includes a slide rod 11, which is fixedly connected to a limiting rod 13. The slide rod 11 is located on the side of the limiting rod 13 near the support plate 6. A sliding sleeve 10 is fixedly connected to the bottom of the material trough 4, and the slide rod 11 passes through the sliding sleeve 10 and slides with it. A limiting spring 12 is sleeved on the outside of the slide rod 11, and the two ends of the limiting spring 12 are fixedly connected to the sliding sleeve 10 and the limiting rod 13, respectively.

[0041] Furthermore, a through groove is provided on the mounting plate 8, and an opening is provided on the side of the through groove near the material trough 4, so that the slider 26 passes through the opening and extends into the through groove, which is beneficial for the slider 26 to slide relative to the through groove. A connecting plate 18 is slidably provided at the bottom of the through groove, and the end of the slide rod 11 away from the limiting rod 13 extends into the through groove and is fixedly connected to the connecting plate 18. The slide rod 11 passes through the mounting plate 8 and is slidably connected to it. A float plate 19 is provided between the pressure block 21 and the connecting plate 18. When the material trough 4 and the mounting plate 8 move below the water surface, the float plate 19 is buoyed and moves between the pressure block 21 and the connecting plate 18. At this time, the pressure block 21 can squeeze the float plate 19 during rotation, and then the float plate 19 drives the slide rod 11 to move outward.

[0042] In order to drive the guide shaft 20 to rotate, a spiral limiting groove 32 is provided on the outer circumferential surface of the guide shaft 20. Specifically, a through hole is provided on the slider 26 so that the guide shaft 20 passes through the through hole and slides with it. A limiting block 33 that slides with the limiting groove 32 is fixedly connected to the inner wall of the through hole.

[0043] Furthermore, a partition 25 is fixedly connected inside the through groove, the guide shaft 20 passes through the partition 25 and is rotatably connected to it, and a support spring 28 is sleeved on the outside of the guide shaft 20, the support spring 28 being disposed between the slider 26 and the partition 25.

[0044] In addition, in order to position the support plate 6, a plurality of sleeve rods 16 are fixedly connected to the bottom end face of the mounting plate 8. Each sleeve rod 16 corresponds to a support plate 6. A top rod 15 is slidably provided at the end of the sleeve rod 16 away from the mounting plate 8. Both the sleeve rod 16 and the top rod 15 are arc-shaped, and their centers are on the same straight line as the rotation center of the support plate 6. The end of the top rod 15 away from the sleeve rod 16 is in contact with the support plate 6 but not fixed. An arc-shaped spring is provided inside the sleeve rod 16, and the two ends of the arc-shaped spring are fixedly connected to the sleeve rod 16 and the top rod 15 respectively.

[0045] In actual use, the entire device is placed at the water inlet and in front of the grid. If the grid is tilted, the chain 7 in the device is also tilted and parallel to the grid. Rotating the chain 7 then helps to rotate the mounting plate 8 and the trough 4. When the trough 4 enters the water and rotates to the grid, the float 19, under buoyancy, moves between the pressure block 21 and the connecting plate 18. When the trough 4 moves to the garbage accumulation area, the garbage is loaded into the trough 4. At this time, the trough 4 experiences significant pressure as it moves upwards out of the water. This causes the material trough 4 to move downward relative to the mounting plate 8. During this process, the slider 26 overcomes the force of the support spring 28 and moves downward relative to the guide shaft 20, thereby causing the limiting block 33 to slide within the limiting groove 32. Since the limiting groove 32 is spiral-shaped, the limiting block 33 will drive the limiting shaft to rotate as it slides downward along the limiting groove 32, which in turn will drive the pressure block 21 to rotate. Since the pressure block 21 is eccentrically set with the guide shaft 20, the pressure block 21 will squeeze the float 19 and drive the float 19 towards the limiting rod during its rotation. As the float 19 moves in the direction of 13, the limit rod 13 can drive the support bar 35 to move outward relative to the trough 4. Since the distance of the multiple locking blocks 14 in a group extending towards the support plate 6 gradually decreases, when the support bar 35 and the locking blocks 14 on one side move outward, some of the locking blocks 14 will be misaligned with the support plate 6. As a result, the support plate 6 corresponding to this part of the locking blocks 14 is not enough to support the garbage on the water surface as the trough 4 moves upward out of the water. This leads to the support plate 6 being unable to support the garbage on the water surface as the trough 4 moves upward out of the water. As the trough 4 moves out of the water, it rotates downward relative to the feed trough 4, making the support plates 6 at the bottom of the feed trough 4 more sparse. This prevents the feed trough 4 from being loaded with too much garbage at once, which helps protect the feed trough 4. As the feed trough 4 moves, the garbage on the water surface will gradually decrease. At this time, the feed trough 4 will not encounter much resistance during the process of moving out of the water surface, thus keeping the multiple support plates 6 at the bottom of the feed trough 4 stable. This is conducive to the treatment of the remaining garbage on the water surface. For smaller garbage, this structure can clean it up more thoroughly.

[0046] After the installation block is removed from the water surface, the float 19 will not be buoyed. At this time, the float 19 moves downward and is offset from the pressure block 21. When the float 19 loses the limit of the pressure block 21, the limiting rod 13 can drive the float 19 to move away from the support bar 35. During this process, the support bar 35 and the locking block 14 can be reset, so that the locking block 14 re-engages with the support plate 6. The set top rod 15 helps to drive the tilted support plate 6 to rotate back to a horizontal state. During the rotation, the support plate 6 will engage with the locking block 14. The first inclined surface 24 on the 4 contacts and presses the locking block 14 into the support bar 35. When the support plate 6 rotates to a horizontal state, the locking block 14 will pop out and be placed at the bottom of the support plate 6 to limit it. At this point, when the mounting plate 8 is removed from the water surface, the support plate 6 that was originally rotating downwards can be reset to a horizontal state, so that the support plates 6 at the bottom of the trough 4 are arranged tightly, which helps to prevent garbage from leaking out between the two support plates 6. As the chain 7 rotates, the trough 4 will move above the water inlet, and the staff can collect the garbage.

[0047] Afterwards, the trough 4 will move to the left side with the chain 7 and re-enter below the water surface. When the trough 4 moves to the left side of the chain 7, since the trough 4 has rotated 180°, the support plate 6 will rotate downward relative to the trough 4 to a vertical position. In this state, during the process of the trough 4 entering the water, the support plate 6 will not bring the garbage on the water surface into the water with it, thus avoiding additional load on the chain 7 when it rotates. By repeating the above process, the garbage on the water surface can be continuously transported upward.

[0048] In summary, this device, through the cooperation of the drive component and the snap-fit ​​component, ensures that the support plate 6 remains vertical during the process of the material trough 4 entering the water, preventing the garbage from being carried into the water along with it. This also avoids adding extra load to the chain 7 when it rotates. Furthermore, the support plates 6 at the bottom of the material trough 4 can be distributed according to the degree of garbage accumulation on the water surface. When there is a lot of garbage, the support plates 6 are distributed more sparsely, preventing the material trough 4 from being loaded with a large amount of garbage at once. This facilitates the even distribution of garbage to each material trough 4 and protects it.

[0049] like Figure 1-2 As shown in Figures 8-11, a fixing frame 5 is provided on the outer side of the chain 7. The fixing frame 5 is provided with an installation groove on the side close to the chain 7, which is conducive to accommodating the chain 7. Both ends of the fixing frame 5 are provided with sprockets, so that the chain 7 can be fitted between the two sprockets. Of course, both ends of the inside of the fixing frame 5 are provided with notches, which is conducive to the sprockets passing through the notches and cooperating with the chain 7.

[0050] A rotating shaft 3 is fixedly connected between two sprockets on the same side. The rotating shaft 3 passes through the fixed frame 5 and is rotatably connected to it. A bracket 1 is fixedly installed on the top of the fixed frame 5. Specifically, the bracket 1 can adopt a truss structure and be installed above the water inlet. A motor is installed inside the bracket 1. An output shaft is provided at the output end of the motor. The output shaft passes through the bracket 1 and is rotatably connected to it. Pulleys are fixedly sleeved on the outer sides of the rotating shaft 3 and the output shaft. A belt 2 is sleeved between the two pulleys. This structure is conducive to driving the sprockets and chain 7 to rotate. Of course, in actual use, the rotating shaft 3 can also be driven to rotate by gear transmission or chain transmission.

[0051] Both sides of the mounting plate 8 are fixedly provided with connecting shafts 9, and the chain 7 is specifically composed of pins, rollers, sleeves 30 and chain plates. The two connecting shafts 9 on one side of the mounting plate 8 are fixedly connected to the two pins at the outer chain plate. Of course, in actual application, a clamp can be pre-installed on the pins and then the connecting shafts 9 can be fixedly connected to the clamp. Fixing a rigid component between the two chains 7 is a mature technical means in the mechanical field, which will not be elaborated here.

[0052] Cover plates 17 are fixedly connected to the top and bottom of the inside of the channel, and the guide shaft 20 is rotatably set between the two cover plates 17. Multiple through round holes are opened on the cover plates 17, which facilitates the water flow through the round holes into the channel.

[0053] A sliding groove 29 is provided on the top surface of the cover plate 17 located at the bottom of the channel. A sleeve 30 is slidably installed in the sliding groove 29. The cross-section of the sleeve 30 and the sliding groove 29 are both T-shaped to prevent the sleeve 30 from detaching from the sliding groove 29. A fixing rod 31 is slidably installed inside the sleeve 30. The top end of the fixing rod 31 is fixedly connected to the float plate 19. A first spring is installed inside the sleeve 30. The two ends of the first spring are fixedly connected to the sleeve 30 and the fixing rod 31, respectively. The top two sides of the float plate 19 are both set as second inclined surfaces 36 to prevent the float plate 19 from interfering with the pressure block 21 during the upward movement. When the mounting plate 8 is removed from the water surface, the first spring helps to drive the float plate 19 to move downward and offset from the pressure block 21. The two sides of the partition plate 25 and the slider 26 here do not need to contact the inner wall of the channel, so that the water can flow normally in the channel.

[0054] like Figure 7-8 As shown, a groove is provided on one side of the limiting rod 13, and the locking block 14 is slidably disposed in the groove. A second spring is provided in the groove, and the two ends of the second spring are fixedly connected to the locking block 14 and the opposite side of the groove, respectively.

[0055] To ensure a stable fit between the material trough 4 and the mounting base, a guide groove can be provided on one side of the mounting plate 8 during actual use. A protrusion 27 that slides with the guide groove is fixedly connected to the material trough 4. Specifically, a support rod is fixedly installed inside the guide groove. The support rod passes through the protrusion 27 and slides with it. A third spring is sleeved on the outside of the support rod. The third spring is located between the protrusion 27 and the bottom end face of the guide groove.

[0056] like Figure 9 As shown, multiple protruding teeth can be evenly arranged on the outer surface of the support bar 35, which is beneficial for cleaning the gaps in the grid.

[0057] like Figure 14 As shown, in order to allow the limiting rod 13 to slide with the support bar 35, a T-shaped groove is provided at the bottom of the support bar 35, and a fixing block 34 is fixedly provided on the top surface of the limiting rod 13. The cross-section of the fixing block 34 is T-shaped, and the fixing block 34 is slidably disposed in the T-shaped groove.
