Description

Technical Field

[0001] This utility model relates to the field of fishpond bottom sediment treatment technology, specifically, to a fishpond bottom sediment collection and treatment device. Background Technology

[0002] During fishpond aquaculture, bottom sediment will continuously accumulate. Its components include fish excrement, uneaten feed, microbial remains, and external pollutants. The physicochemical properties of the bottom sediment directly affect the water quality of the fishpond and the living environment of the fish. Therefore, it is necessary to collect and analyze the bottom sediment regularly in order to develop a scientific bottom sediment cleaning and water quality control plan.

[0003] However, existing fishpond sediment collection devices have significant shortcomings: on the one hand, most devices are difficult to adjust the collection depth flexibly, and cannot adapt to the sediment distribution in fishponds of different water depths or in different areas of the same fishpond, which can easily lead to sampling position deviations and affect the representativeness of the sediment samples; on the other hand, the collection mechanism lacks a buffer protection structure, and when it comes into contact with hard sediment or underwater obstacles, it is easy to damage the components due to excessive impact force, and the collected sediment needs to be transferred to a special container for sampling, which is a cumbersome operation process. Therefore, those skilled in the art provide a fishpond sediment collection and processing device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a device for collecting and processing fishpond bottom sediment, thereby solving the problems in the prior art.

[0006] As a preferred embodiment of the above technical solution, the floating and sinking mechanism includes a connecting seat, which is fixedly connected to the center of the upper end of the support plate. A motor seat is fixedly connected to one side of the upper end of the connecting seat, a controller is fixedly connected to the end of the motor seat away from the connecting seat, and an adjusting motor is fixedly connected to the upper end of the motor seat.

[0009] As a preferred embodiment of the above technical solution, the acquisition mechanism includes a movable column, which is threaded to the outside of the lead screw and slidably connected to the outside of the guide shaft. One end of the movable column is hinged to a hinge, and the end of the hinge away from the movable column is fixedly connected to an acquisition frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a floating and sinking mechanism. Using a connecting base as a stable mounting foundation, the controller precisely controls and adjusts the motor. Through the meshing of the driving and driven gears, the motor power is stably transmitted to the lead screw. Combined with the threaded engagement between the lead screw and the movable column, and the limiting effect of the guide shaft on the movable column, the precise adjustment of the lifting position of the collection mechanism is achieved. Simultaneously, the upper and lower limiting plates and bearings ensure both the stability and smoothness of the lead screw rotation and the fixation of the guide shaft. The entire system can flexibly adapt to different fishpond depths and sediment distributions, precisely adjusting the underwater floating and sinking position of the collection mechanism. This provides a stable foundation for the subsequent efficient and accurate sediment collection, effectively solving the problem of traditional sediment collection devices' difficulty in flexibly adjusting the collection depth and adapting to different fishpond environments, thus improving the adaptability and operational accuracy of the device in sediment collection operations.

[0014] Based on the aforementioned beneficial effects, this utility model is equipped with a collection mechanism and a sampling mechanism. The collection mechanism uses a movable column as the transmission core and achieves stable lifting and lowering through a lead screw and guide shaft. The collection slope plate, in conjunction with a damper, buffers the impact of bottom mud, enabling smooth and damage-free collection of bottom mud, avoiding component damage, and ensuring collection efficiency and bottom mud integrity. The sampling mechanism precisely connects to the sampling slot of the collection frame through a feed pipe, and combines a control valve and a pull handle for convenient sample control, enabling rapid sample acquisition and reducing bottom mud waste. The two work together to achieve integrated collection and sampling, improving operational convenience and accuracy. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-5As shown, this utility model provides a technical solution: a fishpond bottom mud collection and treatment device, including a support plate 1 for connecting the upper and lower components, a floating and sinking mechanism 2 for adjusting the floating and sinking position of the collection is provided at the upper end of the support plate 1, a collection mechanism 3 for collecting fishpond bottom mud is provided on one side of the floating and sinking mechanism 2, and the collection mechanism 3 is provided on the lower side of the support plate 1, and sampling mechanisms 4 for sampling the collected fishpond bottom mud are provided on both sides of the collection mechanism 3.

[0023] The underwater depth of the collection mechanism 3 is adjusted by the buoyancy mechanism 2: the controller 23 sends a command to the adjustment motor 24, which drives the drive gear 25 to rotate. The driven gear 26, which meshes with the drive gear 25, rotates accordingly, thereby driving the lead screw 28 fixed to it to rotate. Since the movable column 31 is threadedly connected to the lead screw 28 and is limited by the guide shaft 29, the movable column 31 moves up and down along the guide shaft 29 when the lead screw 28 rotates, thereby driving the collection mechanism 3, which is hinged below, to adjust its buoyancy position. When the collection mechanism 3 reaches the appropriate depth, the collection frame 33 moves closer to the bottom sediment with the device. When the collection slope 37 contacts the bottom sediment, it is subjected to force and rotates around the hinge point. The damper 35 buffers the force to avoid damage, and at the same time, the bottom sediment is smoothly guided into the cavity of the collection frame 33 to complete the collection. After collection, the bottom mud in the collection frame 33 enters the conveying pipes 41 on both sides through the sampling groove 38. The staff opens the control valve 43 and pulls the pull handle 44. The negative pressure is used to make the bottom mud in the conveying pipe 41 enter the control pipe 42. After closing the control valve 43, the pull handle 44 is pulled out to obtain the bottom mud sample.

[0024] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the floating mechanism 2 includes a connecting seat 21, which is fixedly connected to the center of the upper end of the support plate 1. A motor seat 22 is fixedly connected to one side of the upper end of the connecting seat 21. A controller 23 is fixedly connected to the end of the motor seat 22 away from the connecting seat 21. An adjusting motor 24 is fixedly connected to the upper end of the motor seat 22.

[0025] The connecting seat 21 is fixedly connected to the upper center of the support plate 1, and the motor seat 22 is fixed to one side of the upper end of the connecting seat 21. On the one hand, it provides a stable mounting platform for the adjusting motor 24, ensuring that the adjusting motor 24 will not shift or shake during operation; on the other hand, the end of the motor seat 22 away from the connecting seat 21 is connected to the controller 23, so that the controller 23 can maintain a reasonable distance and connection relationship with the adjusting motor 24, which facilitates stable signal transmission. When it is necessary to adjust the floating position of the acquisition mechanism 3, the operator sends a forward or reverse control signal to the adjusting motor 24 by operating the controller 23. After receiving the signal, the adjusting motor 24 starts, and its output end transmits power to the subsequent transmission components, thereby driving the acquisition mechanism 3 to move up and down, and finally completing the floating adjustment of the acquisition position.

[0026] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, the output end of the regulating motor 24 is rotatably connected to the driving gear 25, and the upper end of the connecting seat 21 is rotatably connected to the driven gear 26. The driven gear 26 and the driving gear 25 are meshed together. The center of the inner cavity of the driven gear 26 is rotatably connected to the shaft, and the shaft passes through the inner cavity of the connecting seat 21.

[0027] The regulating motor 24 serves as the power source. Upon receiving a command from the controller 23, its output begins to rotate, driving the drive gear 25, which is connected to it, to rotate synchronously. Since the driven gear 26 is rotatably connected to the upper end of the connecting seat 21 and meshes with the drive gear 25, the rotation of the drive gear 25 transmits power to the driven gear 26 through tooth meshing, causing the driven gear 26 to rotate around its own rotation center. Furthermore, because the shaft rotatably connected to the center of the driven gear 26 passes through the inner cavity of the connecting seat 21, and the lower end of the shaft is fixedly connected to the lead screw 28 used to drive the lifting and lowering of the acquisition mechanism 3, the rotation of the driven gear 26 directly drives the shaft to rotate synchronously. The shaft then transmits the rotational power to the lead screw 28, providing the power basis for the rotation of the lead screw 28. Finally, through the cooperation of the lead screw 28 and the movable column 31, the acquisition mechanism 3 moves up and down, completing the floating and sinking adjustment of the acquisition position.

[0028] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, a limiting upper plate 27 is fixedly connected to the lower side of the inner cavity of the connecting seat 21. A lead screw 28 is rotatably connected to the inner cavity of the limiting upper plate 27, and the lead screw 28 is fixedly connected to the shaft at the inner cavity of the driven gear 26. Guide shafts 29 are fixedly connected to both sides of the inner cavity of the limiting upper plate 27. A limiting lower plate 210 is fixedly connected to the outer side of the bottom end of the guide shaft 29, and a bearing 211 is rotatably connected to the inner cavity of the limiting lower plate 210, and the bearing 211 is rotatably connected to the outer side of the bottom end of the lead screw 28.

[0029] The upper limiting plate 27 is fixed to the lower side of the center of the inner cavity of the connecting seat 21. The center of its inner cavity radially constrains the lead screw 28 through a rotating connection structure. At the same time, the top of the lead screw 28 is fixed to the shaft at the center of the inner cavity of the driven gear 26. When the driven gear 26 is driven to rotate by the driving gear 25, the shaft can directly transmit the rotational power to the lead screw 28, ensuring that the lead screw 28 rotates synchronously with the shaft and avoiding slippage or displacement during power transmission. The guide shafts 29 fixed on both sides of the inner cavity of the upper limiting plate 27 form a sliding fit with the movable column 31 of the acquisition mechanism 3. When the movable column 31 rises and falls with the lead screw 28, the guide shafts 29 can limit the rotational tendency of the movable column 31, making it move smoothly only along the axial direction of the guide shafts 29, ensuring the accuracy of the lifting direction of the acquisition mechanism 3. The lower limiting plate 210, which is fixed to the outer side of the bottom end of the guide shaft 29, works with the upper limiting plate 27 to fix the upper and lower ends of the guide shaft 29, preventing the guide shaft 29 from shaking during device operation. On the other hand, the bearing 211 at the center of the inner cavity of the lower limiting plate 210 is sleeved on the outer side of the bottom end of the lead screw 28. This not only provides radial limiting for the bottom end of the lead screw 28, preventing it from shifting when rotating at high speed, but also converts the sliding friction between the lead screw 28 and the lower limiting plate 210 into rolling friction inside the bearing 211, significantly reducing the rotational resistance of the lead screw 28 and allowing it to rotate more smoothly under the drive of the shaft, thereby ensuring that the movable column 31 drives the acquisition mechanism 3 to rise and fall stably.

[0030] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, the acquisition mechanism 3 includes a movable column 31, which is threaded to the outside of the lead screw 28 and slidably connected to the outside of the guide shaft 29. One end of the movable column 31 is hinged to a hinge 32, and the end of the hinge 32 away from the movable column 31 is fixedly connected to the acquisition frame 33.

[0031] The movable column 31 is threadedly connected to the outside of the lead screw 28 and slidably connected to the outside of the guide shaft 29. When the lead screw 28 in the buoyancy mechanism 2 rotates forward or backward under the drive of the shaft, the movable column 31 cannot rotate synchronously with the lead screw 28 due to the restriction of the guide shafts 29 on both sides. The rotational motion of the lead screw 28 is then converted into linear motion of the movable column 31 along the axial direction of the guide shaft 29 through threaded engagement, realizing the rise or fall of the movable column 31, which in turn drives the hinge 32, which is hinged at one end, to move synchronously. The hinge 32 can flexibly adapt to the small angle adjustment of the collection frame 33 during underwater operations, avoiding rigid damage to components due to underwater environmental fluctuations or bottom sediment resistance. At the same time, the end of the hinge 32 away from the movable column 31 is fixedly connected to the collection frame 33, which can stably transmit the lifting power of the movable column 31 to the collection frame 33, so that the collection frame 33 can accurately adjust the underwater depth together with the movable column 31. When the designated bottom sediment layer is reached, the bottom sediment collection operation can be completed in conjunction with the structure of the collection frame 33 itself.

[0032] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a fixing plate 34 is fixedly connected to one side of the center of the inner cavity of the collection frame 33. Dampers 35 are fixedly connected to both sides of the bottom end of the fixing plate 34. A connecting ring 36 is fixedly connected to the outer side of the bottom end of the damper 35. A collection slope plate 37 is fixedly connected to the bottom end of the connecting ring 36. The end of the collection slope plate 37 near the hinge 32 is hinged to the collection frame 33. Sampling slots 38 are opened on both sides of the inner cavity of the collection frame 33.

[0033] A fixed plate 34, located on one side of the center of the inner cavity of the collection frame 33, provides a stable mounting base for the damper 35, ensuring that the damper 35 will not shift during stress. When the collection frame 33 descends to the bottom of the fishpond with the movable column 31 and contacts the bottom mud, the collection slope plate 37 first contacts the surface of the bottom mud. Since the end of the collection slope plate 37 near the hinge 32 is hinged to the collection frame 33, the upward impact force generated by the bottom mud on the collection slope plate 37 will cause the collection slope plate 37 to rotate around the hinge point. At this time, the dampers 35 on both sides of the bottom end of the fixed plate 34 play a buffering role, absorbing the impact force through their own damping characteristics, preventing the collection slope plate 37 from deforming or being damaged due to excessive instantaneous force, and at the same time allowing the collection slope plate 37 to rotate at a gentle angle, forming an inclined slope surface that facilitates the introduction of bottom mud, guiding the bottom mud to slide smoothly into the inner cavity of the collection frame 33. After the bottom sediment is collected, the sampling slots 38 on both sides of the inner cavity of the collection frame 33 can be precisely connected with the feed pipe 41 of the sampling mechanism 4, providing a channel for extracting samples from the collected bottom sediment.

[0034] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, the sampling mechanism 4 includes a feeding pipe 41, which is fixedly connected to both sides of the collection frame 33. The inner cavity of the feeding pipe 41 has a slot with the same inner diameter as the sampling groove 38. A control pipe 42 is fixedly connected to the end of the feeding pipe 41 away from the collection frame 33. A control valve 43 is fixedly connected to the upper end of the control pipe 42. A pull handle 44 is slidably connected to the inner cavity of the end of the control pipe 42 away from the feeding pipe 41.

[0035] The conveying pipe 41 is fixedly connected to both sides of the collection frame 33 to ensure that its relative position with the collection frame 33 is stable; and the inner cavity groove of the conveying pipe 41 has the same inner diameter as the sampling groove 38 of the collection frame 33, which can achieve precise docking between the two, avoid leakage or residue of bottom mud during the transmission process, and allow the bottom mud collected in the collection frame 33 to smoothly enter the interior of the conveying pipe 41 through the sampling groove 38. The end of the conveying pipe 41 furthest from the collection frame 33 is fixedly connected to the control pipe 42, forming a complete sediment transport path. The control valve 43 at the upper end of the control pipe 42 acts as a flow switch. Before sampling, the control valve 43 is closed to prevent sediment from entering the control pipe 42 prematurely. When sampling is required, the operator opens the control valve 43 to connect the channel between the conveying pipe 41 and the control pipe 42. Then, the pull handle 44 at the end of the control pipe 42 furthest from the conveying pipe 41 is pulled. When the pull handle 44 slides, a negative pressure is created inside the control pipe 42. Under the action of the negative pressure, the sediment in the conveying pipe 41 will quickly enter the control pipe 42 along the transport path. After a sufficient amount of sediment sample has been collected in the control pipe 42, the control valve 43 is closed to block the passage, and then the pull handle 44 is pulled out to obtain a complete sediment sample from the control pipe 42.

[0036] Working Principle: During operation, the support plate 1 serves as the core connection base. The sampling depth is first adjusted via the buoyancy mechanism 2. The controller 23 sends a command to the adjusting motor 24, which drives the drive gear 25 to rotate. The driven gear 26, meshing with the drive gear 25, rotates accordingly, thereby driving the lead screw 28 connected to its inner shaft to rotate synchronously. When the lead screw 28 rotates, the movable column 31, which is threaded to the lead screw 28 and limited by the guide shaft 29, moves up and down along the guide shaft 29, realizing the buoyancy adjustment of the sampling mechanism 3. During this process, the upper limiting plate 27, the lower limiting plate 210, and the bearing 211 ensure the stable rotation of the lead screw 28 and its fixation to the guide shaft 29. When the sampling mechanism 3 reaches the specified depth, the sampling frame 33 contacts the bottom mud. The sampling slope plate 37 rotates around the hinge point under the force of the bottom mud. The damper 35 connected to the fixed plate 34 buffers the impact force, guiding the bottom mud smoothly into the sampling frame 33 to complete the sampling. After collection is completed, the sampling mechanism 4 is activated: the bottom mud in the collection frame 33 enters the conveying pipes 41 on both sides through the sampling groove 38. The staff opens the control valve 43 on the control pipe 42 and pulls the pull handle 44 to generate negative pressure, so that the bottom mud in the conveying pipe 41 enters the control pipe 42. After closing the control valve 43, the pull handle 44 is pulled out to obtain the bottom mud sample, thus realizing the integrated operation of bottom mud collection, depth adjustment and sampling.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
