Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, specifically a cleaning device for water quality sampling tools. Background Technology

[0002] Water quality sampling and testing is a fundamental task in environmental monitoring, water resource management, and pollution control. The cleanliness of sampling tools directly affects the accuracy and reliability of water sample data.

[0003] An existing rapid sampling device for water quality testing, such as the one disclosed in announcement number CN220982769U, relies on manual operation, requiring manual cleaning of the sampling cylinder after sampling. However, this cleaning method has significant shortcomings:

[0004] 1) Sampling cylinders usually have hinged lids, which are difficult to open completely during cleaning, resulting in water or contaminants remaining at the opening and hinge, affecting the accuracy of subsequent sampling results.

[0005] 2) Cleaning often involves static rinsing or manual scrubbing, which is inefficient and incomplete. In addition, operators frequently come into contact with water samples, posing health and safety risks. Utility Model Content

[0006] This invention provides a cleaning device for water sampling tools, thereby solving the problems of low efficiency and incomplete cleaning in existing water sampling and testing technologies.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for water quality sampling tools, comprising a mounting base and a sampling bucket to be cleaned. Mounting brackets are fixedly mounted on both sides of the mounting base. A cleaning box is fixedly positioned at the middle of the upper end of the mounting base, located between the two mounting brackets. A driving mechanism is fixedly mounted on the upper end of each mounting bracket. A fixing mechanism for fixing the sampling bucket to be cleaned in the cleaning box is mounted on the driving mechanism. The fixing mechanism is located above the cleaning box, and the sampling bucket to be cleaned is located above the mounting base.

[0008] Preferably, the driving mechanism includes a circular slide rail fixed at the upper end of the mounting bracket, an arc-shaped through hole on the inner side of the circular slide rail, an external gear ring slidably disposed in the circular slide rail, a mounting base symmetrically fixedly mounted on the inner side of the external gear ring, and an external gear for driving the external gear ring to rotate at the arc-shaped through hole.

[0009] Preferably, an assembly base is fixedly installed on the outer wall of the circular slide rail, and a first drive motor for driving the external gear is fixedly installed on the assembly base. The circular slide rail is provided with an annular groove that slides and connects with the upper and lower ends of the external gear ring.

[0010] Preferably, the fixing mechanism is installed on the mounting base. The fixing mechanism includes a drive gear, a transmission gear, and a hydraulic cylinder. The drive gear and the transmission gear are located on one side of the mounting base and are meshed together. The drive gear, the transmission gear, and the hydraulic cylinder are arranged in a centrally symmetrical manner. A second drive motor for driving the drive gear is fixedly installed on the upper end of the mounting base.

[0011] Preferably, an arc-shaped clamping rod is fixedly installed on the upper end of the drive gear and the transmission gear, the hydraulic cylinder is located on the mounting base on the other side, and an arc-shaped plate for cooperating with the arc-shaped clamping rod is fixedly installed on the top end of the hydraulic cylinder.

[0012] Preferably, the bottom of the cleaning tank is provided with a circular turntable, and a rectangular limiting plate is fixedly installed on the upper end of the circular turntable. The rectangular limiting plate is used to push open the hinge plates on both sides of the opening end of the sampling bucket to be cleaned. The cleaning tank is provided with a circular sliding groove for slidingly connecting the circular turntable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the hinge plates on both sides of the opening end of the sampling bucket to be cleaned are opened by the rectangular limiting plate, so that the opening of the sampling bucket to be cleaned is open and the water flow can directly enter the sampling bucket to be cleaned for thorough rinsing. This helps to solve the problem of difficulty in cleaning the area below the hinge plate in traditional cleaning. At the same time, the design of the circular slide rail and the external toothed ring allows the entire fixing mechanism to drive the sampling bucket to be cleaned to rotate 360 ​​degrees, so that the water flow can wash every inner wall surface when the sampling bucket is rotated, which helps to improve the cleaning efficiency.

[0015] 2. In this utility model, by having operators place and remove the sampling buckets to be cleaned, direct contact with potentially harmful residual water samples is minimized, effectively improving operational safety. Furthermore, by using a hydraulic cylinder to push an arc-shaped plate, which works in conjunction with an arc-shaped clamping rod driven by a drive gear, the sampling buckets to be cleaned are automatically clamped and released. This helps reduce the hassle of manual tightening and fixing, effectively reducing the labor intensity of operators. At the same time, the fixing mechanism uses two centrally symmetrical arc-shaped clamping rods and an arc-shaped plate to work together, applying force evenly from multiple directions. This can firmly hold sampling buckets of different sizes to be cleaned, preventing them from shaking or falling off during high-speed rotation or rinsing, thus ensuring both the cleaning effect and protecting the equipment itself.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-4 As shown, a cleaning device for water sampling tools includes a mounting base 1 and a sampling bucket 6 to be cleaned. Mounting brackets 2 are fixedly installed on both sides of the top of the mounting base 1, and a cleaning tank 3 is fixedly installed at the middle of the top of the mounting base 1. A drive mechanism 4 is fixedly installed on the top of the mounting brackets 2. The drive mechanism 4 includes a circular slide rail 45 fixed at the upper end of the mounting brackets 2. An arc-shaped through hole is opened on the inner side of the circular slide rail 45. An external gear ring 44 is slidably arranged in the circular slide rail 45. Mounting bases 46 are symmetrically fixedly installed on the inner side of the external gear ring 44. An external gear 42 for driving the external gear ring 44 to rotate is provided at the arc-shaped through hole. The circular slide rail 45 has an annular groove structure with an arc-shaped through hole on its inner side wall for the external gear 42 to pass through. The outer wall is fixed to the mounting base 41 by bolts. A first drive motor 43 is fixed on the mounting base 41 by a motor seat. The output shaft of the motor is connected to the external gear 42 by a key to realize the power drive of the external gear 42.

[0025] An external gear ring 44 is nested inside a circular slide rail 45, with its upper and lower ends embedded in the annular groove 47 of the circular slide rail 45. Sliding connection is achieved through ball bearings within the groove, ensuring that the external gear ring 44 can rotate 360 ​​degrees along the annular groove 47. The outer teeth of the external gear ring 44 mesh with the external gear 42, forming a gear transmission pair to transmit power to the first drive motor 43. Two mounting bases 46 are symmetrically welded to the inner side of the external gear ring 44, serving as mounting carriers for the fixing mechanism 5 and ensuring that the fixing mechanism 5 rotates synchronously with the external gear ring 44. An assembly base 41 is fixedly mounted on the outer wall of the circular slide rail 45, and the first drive motor 43 for driving the external gear 42 is fixedly mounted on the assembly base 41. An annular groove 47 is provided inside the circular slide rail 45, which is slidably connected to the upper and lower ends of the external gear ring 44.

[0026] A fixing mechanism 5 is installed on the drive mechanism 4 to fix the sampling bucket 6 to be cleaned to the cleaning box 3. The fixing mechanism 5 is located on the mounting base 46. The fixing mechanism 5 includes a drive gear 51, a transmission gear 52 and a hydraulic cylinder 54. The drive gear 51 and the transmission gear 52 are meshed. An arc-shaped clamping rod 53 is fixedly installed at the top of the drive gear 51 and the transmission gear 52. An arc-shaped plate 55 for cooperating with the arc-shaped clamping rod 53 is fixedly installed at the top of the hydraulic cylinder 54. A circular turntable 57 is rotatably provided at the bottom of the cleaning box 3. A rectangular limiting plate 56 is fixedly installed at the top of the circular turntable 57. The rectangular limiting plate 56 is used to open the hinge plates on both sides of the opening end of the sampling bucket 6 to be cleaned. There are two arc-shaped clamping rods 53. It is preferable to set two symmetrical arc plates 55 to help to clamp and fix the sampling bucket 6 to be cleaned more stably. The arc plate 55 on the other side is fixed at the inner ring position of the outer toothed ring 44.

[0027] The second drive motor is fixed to the top of the mounting base 46 on one side by bolts, with its output shaft facing upward. The output shaft of the second drive motor is connected to the drive gear 51 by a key. The drive gear 51 meshes with the transmission gear 52 to form a symmetrical gear transmission structure. The tops of the drive gear 51 and the transmission gear 52 are fixed by welding an arc-shaped clamp 53 to ensure that the clamp rotates synchronously in opposite directions when the gears rotate.

[0028] On the other side, a hydraulic cylinder 54 is fixed to the mounting base 46 by bolts. The hydraulic cylinder 54 faces to the right, the piston rod faces to the right, and the top of the piston rod is fixed to the arc plate 55 by bolts. The arc plate 55 matches the arc of the arc clamping rod 53, and a rubber pad can be added to the inner side to increase friction. The arc plate 55 on the other side is directly fixed to the inner ring of the outer toothed ring 44 by a bracket, forming a symmetrical clamping structure with the arc plate 55 driven by the hydraulic cylinder 54.

[0029] The drive gear 51, transmission gear 52, and hydraulic cylinder 54 are centrally symmetrically distributed on the mounting base 46 to ensure uniform clamping force on the sampling bucket 6 to be cleaned. It should be noted that the first drive motor 43, the second drive motor, and the hydraulic cylinder 54 are all controlled by a servo controller.

[0030] The cleaning chamber 3 is positioned at the center of the mounting bracket 2, and a circular through hole is provided at the top of the cleaning chamber 3 for placing the sampling bucket 6 to be cleaned. The fixing mechanism 5 is located above the cleaning chamber 3, and the sampling bucket 6 to be cleaned is located above the mounting base 1. The cleaning chamber 3 is provided with a circular groove 58 for sliding connection of the circular turntable 57, and a second drive motor for driving the drive gear 51 is fixedly installed at the top of the mounting base 46.

[0031] It should be noted that the specific models and specifications of the first drive motor 43, the second drive motor, and the hydraulic cylinder 54 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] When it is necessary to clean the sampling container 6, the operator first places the sampling container 6 on the circular turntable 57 inside the water-filled cleaning tank 3. At this time, the hinge plate of the sampling container 6 is usually in the open state under the pressure of the rectangular limiting plate 56, and at the same time, the rectangular limiting plate 56 initially fixes the sampling container 6.

[0034] Subsequently, the hydraulic cylinder 54 is activated, and its output end pushes the arc-shaped plate 55 to the right, applying pressure to the right from the outside of the sampling bucket 6 to be cleaned. The second drive motor is then activated to drive the drive gear 51 to rotate. Since the drive gear 51 meshes with the transmission gear 52, it will synchronously drive the arc-shaped clamping rod 53 at its top to rotate in opposite directions, clamping the sampling bucket 6 from the outside.

[0035] Next, the first drive motor 43 is started and begins to work, driving the external drive gear 42 to rotate. Since the external drive gear 42 meshes with the external gear ring 44 that is slidably set in the circular slide rail 45, the power transmission enables the external gear ring 44 to rotate 360 ​​degrees along the annular groove 47.

[0036] At the same time, the mounting base 46, which is fixedly installed inside the outer toothed ring 44, also rotates, and the fixing mechanism 5 also drives the sampling bucket 6 to be cleaned to rotate inside the cleaning box 3.

[0037] Because the sampling bucket 6 to be cleaned is in a state of rapid 360-degree rotation, every surface of its inner and outer walls can be fully washed by the water flow.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
