Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a floating garbage salvaging device for sewage treatment. Background Art

[0002] With the development of industrialization and urbanization, water pollution is becoming increasingly serious. Floating garbage in sewage not only affects water quality, but may also clog pipes, damage treatment equipment, and even aggravate eutrophication of water bodies. In order to improve sewage treatment efficiency, various types of floating garbage salvage devices are widely used. Their core goal is to efficiently collect floating objects, reduce maintenance costs, and improve water purification effects.

[0003] For example, a floating trash can in "CN106697679A" includes a trash can body, a water inlet is provided at the top of the trash can body, a water pump is provided at the bottom of the trash can body, the water inlet is immersed in the water surface, and a positioning device for maintaining the water level line of the trash can body is provided on the trash can body. It can be seen from the above scheme that a water inlet is provided at the top of the trash can body, the water inlet is immersed in the water surface, the water inlet is flush with the water surface or lower than the water surface, the water pump continuously draws water into the trash can body from the water inlet of the trash can body, the garbage is left in the trash can body, and the water is discharged from the trash can body by the water pump. The positioning device can timely adjust the height of the water level line of the trash can body when the water level changes, maintain the height difference between the water inlet and the water surface, facilitate the collection of garbage, and prevent the trash can body from floating away with the water flow.

[0004] In the prior art, a floating garbage can is often used to salvage floating garbage. Its working principle is to use a water pump to generate negative pressure in the bucket to form a water flow, so as to suck the floating garbage on the water surface into the filter in the bucket. The water is discharged after filtering, and the garbage is left in the filter. As shown in the above patent, this method is simple and efficient to clean floating garbage. However, when there is a lot of garbage in the filter, the staff needs to manually take it out and dump it and then reinstall it. If the staff fails to clean the garbage in the bucket in time, the garbage will overflow from the bucket. If the device can remove the garbage by itself, it can greatly reduce the labor of the staff to frequently dump the garbage, and there is no need to worry about overflow caused by too much garbage. Therefore, there is an urgent need for a floating garbage salvaging device for sewage treatment that can automatically remove garbage. Summary of the invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem in the prior art that floating garbage salvaging equipment cannot remove garbage by itself.

An arc-shaped support is symmetrically provided in the feeding chamber, and the outer wall of the arc-shaped support is rotatably connected to the corresponding partition. The outer wall of the arc-shaped support is assembled and connected to the partition through a first spring. In the initial state, the arc-shaped support is pulled by the first spring to expand toward one side of the partition. When the limiting cylinder falls into the arc-shaped support, the arc-shaped support is pressed to close under the action of gravity, and the limiting cylinder is wrapped inside, thereby achieving a limiting effect on the limiting cylinder, so that the limiting cylinder and the feed port are in the same straight line.

[0011] Furthermore, positioning seats are respectively provided below and on both sides of one end of the limiting cylinder, the fixed block and the movable block are respectively engaged in the positioning seats on one side and below and have the same engaging structure, the movable block is provided with an insert block on the side facing the positioning seat, the inner side of the positioning seat is provided with an engaging mechanism engaged with the insert block, and a counterweight bar is provided on the inner side of the limiting cylinder at the movable block, and the counterweight bar is provided to facilitate the movable block to be at the bottom when loading.

[0012] Furthermore, the clamping mechanism includes a second spring, a sliding seat and a limiting ball, and the positioning seat is assembled and connected to the sliding seat at one end away from the opening through a second spring, and the sliding seat is slidably arranged in the positioning seat, and the inner walls of the sliding seat and the positioning seat are both trapezoidal, and the side walls of the sliding seat are provided with a circular groove, and side grooves are provided on both sides of the insert block, and the limiting ball is located between the side groove, the circular groove and the inner wall of the positioning seat, and a first magnetic block is provided on the inner side of the end face of the first slide rail, and the moving card block and the slide seat are both magnetic structures, and the moving card block and the slide seat are magnetically repelled, and the moving card block and the first magnetic block are magnetically attracted. When the moving card block moves to the first magnetic block position, the first magnetic block repels the slide seat and moves the slide seat in a direction away from the moving card block, so that the limiting ball has more space to move, until the limiting ball is squeezed out of the side groove, and the moving card block can be separated from the slide seat and adsorbed on the first slide rail under the suction force of the first magnetic block.

[0013] Furthermore, an inner rail is connected to the side walls of the water trash can body below the first slide rail and the second slide rail, a waterproof motor is slidably arranged in the inner rail, a main gear is arranged at the output end of the waterproof motor through a second cylinder, a mounting groove is arranged at the center of the moving block, a gear sleeve rotatably arranged in the mounting groove and meshing with the main gear is arranged, a side gear is rotatably arranged on one side of the moving block, a rack meshing with the side gear is arranged on one side of the first slide rail, the side gear and the main gear are linked by a belt, when the moving block or the fixed block moves to the corresponding first slide rail or the slot, the second cylinder is extended to extend the main gear into the gear sleeve, the waterproof motor is driven to drive the main gear to rotate, and then the side gear is driven to rotate, the side gear is meshed with the rack, and the moving block can be moved in the first slide rail.

[0014] Furthermore, a limiting groove is provided on the side of the movable block away from the side gear, and a ring is provided at one end of the limiting groove for slidingly sleeved with a soft rope. A push bar is provided in the limiting groove through a third cylinder. The limiting groove is arranged on the side of the first slide rail close to the center of the circle, and a U-shaped groove is provided on the side of the first slide rail close to the center of the circle. When the movable block moves in the first slide rail, the third cylinder drives the extendable push bar to push the soft rope in the limiting groove into the U-shaped groove, and the setting of the U-shaped groove acts like a hook to mount the soft rope, thereby ensuring the stability of the soft rope.

[0015] Furthermore, the first slide rail is connected to the end faces of the second slide rail and the two slots by longitudinal rails, and upper support plates are respectively provided below the feeding end of the first slide rail and below a slot above it. A fourth cylinder is provided in the annular frame, and the output end of the fourth cylinder is assembled and connected to the upper support plate. When the movable card block moves to the end face of the first slide rail, the fourth cylinder is driven to contract, driving the upper support plate to contract to the inside of the annular frame to separate it from the first slide rail and the slot. At this time, the first slide rail is connected to the longitudinal rail, and the slot is connected to the corresponding longitudinal rail, and the movable card block and the fixed card block fall into the second slide rail and the slot below.

[0016] Furthermore, a lower support plate is provided below the end surface of the second slide rail and below the lower slot, respectively. The lower support plate is driven by a fifth cylinder. The upper support plate has the same structure as the lower support plate. When the garbage net needs to be separated from the cylinder body, the fifth cylinder can be retracted so that the movable block and the fixed block are completely separated from the second slide rail and the slot until they fall off.

[0017] Furthermore, the tensioning mechanism includes a first motor, a rotating shaft and an arc-shaped hook. The rotating shaft is rotatably arranged on the inner side of the annular frame at the lower slot, and the arc-shaped hook is arranged at the center position of the rotating shaft. The rotating shaft is driven to rotate by the first motor, and both ends of the soft rope are assembled and connected with the fixed card block. The pull rope is exposed between the two ends of the soft rope, and the arc-shaped hook is located at the position where the pull rope is exposed. By driving the first motor, the rotating shaft is driven to rotate and the pull rope is hooked out by the arc-shaped hook. Continuous rotation can continuously pull out the pull rope until the garbage net port is tightened, thereby disengaging the movable card block and the fixed card block from the second slide rail and the slot, and the packaged garbage net falls into the collection frame for collection.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention stores a large number of garbage nets in the annular frame. When replacement is needed, the garbage net full of garbage is moved down a certain distance to the second slide rail, and the limiting cylinder with the garbage net is introduced from the annular frame into the water garbage can body. During the introduction process, the garbage net can be unfolded by the cooperation of the movable card block and the fixed card block, and the garbage net below can be sealed and dropped by the tightening mechanism, which effectively saves the labor of the staff for frequent dumping of garbage and avoids the situation of garbage overflow caused by forgetting to dump.

[0020] 2. The present invention moves the garbage net filled with garbage downward without sealing it, and then unfolds a new garbage net. In this process, new garbage will be generated, such as the limiting cylinder separated from the garbage net, which can directly fall into the garbage net for collection, thereby avoiding the omission of garbage.

[0021] 3. The counterweight bar provided in the present invention facilitates the moving block to be at the bottom during loading.

[0022] 4. The present invention provides a collection frame below the main body of the floating garbage can, so that the sealed garbage net can be dropped into the collection frame, which is convenient for staff to collect the garbage in a centralized manner. BRIEF DESCRIPTION OF THE DRAWINGS

The output end of the feeding conveyor belt 4 is located at the upper end of the other partition 5. The outer wall of the feeding conveyor belt 4 is provided with a limit support 11. The feeding operation of the garbage net 7 can be realized by driving the feeding conveyor belt 4.

[0045] like Figure 1-Figure 14As shown, a first cylinder 121 is provided on the inner wall of the annular frame 2, and the output end of the first cylinder 121 is assembled and connected with the push plate 912. An arc-shaped support 122 is symmetrically provided in the feeding chamber. The outer wall of the arc-shaped support 122 is rotatably connected with the corresponding partition 5.

A counterweight bar 133 is provided on the inner side of the limiting cylinder 6 at the movable block 812. The counterweight bar 133 is arranged to facilitate the movable block 812 to be at the bottom when loading.

[0047] like Figure 1-Figure 14 As shown, the locking mechanism includes a second spring 141, a slide seat 142 and a limiting ball 143. The end of the positioning seat 131 away from the opening is assembled and connected with the slide seat 142 through the second spring 141. The slide seat 142 is slidably set in the positioning seat 131. The inner walls of the slide seat 142 and the positioning seat 131 are both trapezoidal. A circular groove 144 is opened on the side wall of the slide seat 142, and side grooves 145 are opened on both sides of the insert block 132. The limiting ball 143 is located between the side groove 145, the circular groove 144 and the inner wall of the positioning seat 131. A first magnetic block 146 is provided on the inner side of the end face of the first slide rail 101 to move the clamping block. 812 and the slide 142 are both magnetic structures. The movable block 812 and the slide 142 are magnetically repelled, and the movable block 812 and the first magnetic block 146 are magnetically attracted. When the movable block 812 moves to the position of the first magnetic block 146, the first magnetic block 146 repels the slide 142 and moves the slide 142 away from the movable block 812, so that the limiting ball 143 has more space to move, until the limiting ball 143 is squeezed out of the side groove 145, the movable block 812 can be separated from the slide 142 under the suction force of the first magnetic block 146 and adsorbed to the first slide rail 101.

[0048] like Figure 1-Figure 14As shown, the side walls of the floating garbage can body 1 below the first slide rail 101 and the second slide rail 102 are connected to each other with an inner rail 151, a waterproof motor 152 is slidably arranged in the inner rail 151, and a main gear 154 is arranged at the output end of the waterproof motor 152 through a second cylinder 153. A mounting groove 155 is arranged at the center of the mobile block 812, and a gear sleeve 156 is rotatably arranged in the mounting groove 155 and meshed with the main gear 154. A side gear 157 is rotatably arranged on one side of the mobile block 812, and a side gear 157 is rotatably arranged on one side of the first slide rail 101 and meshed with the side gear 154. 7 is meshed with the rack 158, and the side gear 157 is linked with the main gear 154 through a belt. When the movable block 812 or the fixed block 811 moves to the corresponding first slide rail 101 or the slot 103, the second cylinder 153 is extended to extend the main gear 154 into the gear sleeve 156, and the waterproof motor 152 is driven to drive the main gear 154 to rotate, thereby driving the side gear 157 to rotate, and the side gear 157 is meshed with the rack 158, so that the movable block 812 can be moved in the first slide rail 101.

[0049] like Figure 1-Figure 14 As shown, a limiting groove 161 is provided on the side of the movable block 812 away from the side gear 157, and a ring 162 is provided at one end of the limiting groove 161 for slidingly sleeved with a soft rope 813, and a push bar 163 is provided in the limiting groove 161 through a third cylinder 164, and the limiting groove 161 is arranged on the side of the first slide rail 101 close to the center of the circle, and a U-shaped groove 165 is provided on the side of the first slide rail 101 close to the center of the circle. When the movable block 812 moves in the first slide rail 101, the third cylinder 164 drives the extendable push bar 163 to push the soft rope 813 in the limiting groove 161 into the U-shaped groove 165, and the setting of the U-shaped groove 165 is similar to the function of a hook to mount the soft rope 813, thereby ensuring the stability of the soft rope 813.

[0050] like Figure 1-Figure 14 As shown, the first slide rail 101 and the second slide rail 102 end faces and the two slots 103 are connected by longitudinal rails 171, and upper support plates 172 are respectively provided below the feeding end of the first slide rail 101 and below the upper slot 103. A fourth cylinder 173 is provided in the annular frame 2, and the output end of the fourth cylinder 173 is assembled and connected with the upper support plate 172. When the movable block 812 moves to the end face of the first slide rail 101, the fourth cylinder 173 is driven to contract, driving the upper support plate 172 to contract to the inside of the annular frame 2 to separate it from the first slide rail 101 and the slot 103. At this time, the first slide rail 101 is connected with the longitudinal rail 171, and the slot 103 is connected with the corresponding longitudinal rail 171, and the movable block 812 and the fixed block 811 fall into the second slide rail 102 and the slot 103 below.

[0051] like Figure 1-Figure 14As shown, a lower support plate 175 is provided below the end surface of the second slide rail 102 and below a slot 103, respectively. The lower support plate 175 is driven by the fifth cylinder 174. The upper support plate 172 has the same structure as the lower support plate 175. When the garbage net 7 needs to be separated from the cylinder body, the fifth cylinder 174 can be retracted to allow the movable block 812 and the fixed block 811 to be completely separated from the second slide rail 102 and the slot 103 until they fall off.

[0052] like Figure 1-Figure 14 As shown, the tensioning mechanism includes a first motor 181, a rotating shaft 182 and an arc-shaped hook 183. The rotating shaft 182 is rotatably arranged on the inner side of the annular frame 2 at the lower card slot 103. The arc-shaped hook 183 is arranged at the center position of the rotating shaft 182. The rotating shaft 182 is driven to rotate by the first motor 181. The two ends of the soft rope 813 are assembled and connected with the fixed card block 811. The pull rope 814 is exposed and arranged between the two ends of the soft rope 813. The arc-shaped hook 183 is located at the position where the pull rope 814 is exposed to the outside. By driving the first motor 181, the rotating shaft 182 is driven to rotate, and the pull rope 814 is hooked out by the arc-shaped hook 183. Continuous rotation can continuously pull out the pull rope 814 until the port of the garbage net 7 is tightened, thereby disengaging the movable card block 812 and the fixed card block 811 from the second slide rail 102 and the card slot 103, and the packaged garbage net 7 falls into the collection frame 3 for collection.

[0053] Working principle: When performing floating object salvage operations, the floating garbage can body 1 is placed on the sewage, and a negative pressure is generated in the can using a built-in water pump to form a water flow, so that the floating garbage on the water surface is sucked into the filter in the can. The water is discharged after filtering, and the garbage is left in the filter. When there is a lot of garbage collected in the garbage net 7, it can be replaced. Specifically, the garbage net 7 located on the first slide rail 101 is first moved to the second slide rail 102 below, and the mobile card block 812 is first driven to pull the soft rope 813 to disengage from the first slide rail 101. The mobile card block 812 is located at the other end of the first slide rail 101. At this time, the fixed card block 811 and the mobile card block 812 are moved to a card slot 10 below through the longitudinal rail 171. 3 and the second slide rail 102, and then drive the moving block 812 to unfold the garbage net 7. At this time, the garbage net 7 is still in the unfolded state, and then the new garbage net 7 is loaded, and the loading conveyor belt 4 is driven to convey a limiting cylinder 6 into the loading chamber. Under the action of the counterweight bar 133, the position where the counterweight bar 133 is provided is at the bottom of the limiting cylinder 6. At this time, the moving block 812 is at the bottom, and the fixed block 811 is at the side. The first cylinder 121 is driven to drive the push plate 912 to move, and the limiting cylinder 6 is pushed and pushed out toward the feeding port 911, until the moving block 812 and the fixed block 811 are respectively at the positions of the first slide rail 101 and the card slot 103. Due to their internal magnetic attraction, The movable card block 812 and the fixed card block 811 can be respectively moved out from the side wall of the limiting cylinder 6 and adsorbed and engaged in the first slide rail 101 and the card slot 103. The movable card block 812 and the fixed card block 811 after being moved out are completely separated from the limiting cylinder 6, and the push plate 912 continues to push to completely push the limiting cylinder 6 out of the feed port 911 and drop it into an unfolded garbage net 7 below. At this time, the movable card block 812 moves in the first slide rail 101. During the movement, the movable card block 812 is sleeved on the outside of the soft rope 813, and the soft rope 813 is pulled to slide in the first slide rail 101. When moving, the soft rope 813 is squeezed toward the inside of the first slide rail 101, and the soft rope 813 is inserted to achieve positioning. The card block 812 continues to move until it moves to the other end of the first slide rail 101. At this time, the garbage net 7 is fully unfolded, and the garbage net 7 below can be dropped off. When dropping off, the mobile card block 812 on the second slide rail 102 is first moved to the other end. During the movement, the soft rope 813 can be separated from the second slide rail 102 at the place where the mobile card block 812 passes, and the tensioning mechanism is driven to tighten the pull rope 814 to seal the garbage net 7. Finally, the mobile card block 812 and the fixed card block 811 can be detached from the second slide rail 102 and the lower card slot 103 respectively. The detached garbage net 7 falls into the collection frame 3 directly below under the action of gravity, which is convenient for the staff to concentrate on salvaging.
