Description

Technical Field

[0001] This utility model relates to water quality testing equipment, and more specifically, to a testing auxiliary component for online water quality testing. Background Technology

[0002] With increasing emphasis on environmental protection and water quality monitoring, accurate and timely water quality testing is crucial for safeguarding aquatic ecosystem security and human health. Wastewater testing often involves measuring key indicators such as total phosphorus, total nitrogen, pH, and COD to assess water quality. In water quality testing, some processes are automated, with test tubes transported between stations and then gripped by robotic arms, achieving a degree of automation. However, the robotic arms must ensure accurate positioning of the test tubes during gripping; even slight tilting or misalignment can cause the arms to lose sight of the tubes, leading to misalignment or even detachment.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detection auxiliary component for online water quality detection.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a detection auxiliary component for online water quality detection, including a conveyor belt capable of moving along a preset direction; and several test tube clamping mechanisms, each including a conveyor box, a fixed frame, and a movable frame. The conveyor box is mounted on the conveyor belt, the fixed frame is vertically fixed inside the conveyor box, and the movable frame is vertically oriented and rotatably connected to the conveyor box via a rotating shaft. A pressure block is fixedly mounted on the upper end of the movable frame. A first limiting groove with a vertical orientation is provided on the side of the fixed frame facing the movable frame, and a second limiting groove with a vertical orientation is provided on the side of the pressure block facing the fixed frame. The first limiting groove and the second limiting groove are arranged opposite to each other to accommodate and restrict test tubes.

[0006] In this embodiment, the fixing frame is further configured such that several sets of limiting ribs are fixedly connected to the outer side of the limiting groove, and each set of limiting ribs has two ribs.

[0007] In this embodiment, the lower end of the movable frame is fixedly connected to a bottom support block, the bottom support block protrudes toward the fixed frame, and the bottom support block can press against the bottom of the test tube.

[0008] In this embodiment, the bottom support block is further configured to protrude at an angle toward the fixing frame, and a limiting recess is formed on the upper surface of the bottom support block.

[0009] In this embodiment, the rotating shaft is further configured to be horizontal, and the distance between the rotating shaft and the pressure block is greater than the distance between the rotating shaft and the bottom support block.

[0010] In this embodiment, the movable frame is further configured such that a spring is elastically pressed against the side of the fixed frame facing away from the movable frame, and the pressing position of the spring is located on the lower side of the rotating shaft.

[0011] In this embodiment, one end of the spring is connected to the movable frame, and the other end elastically abuts against the inner wall of the conveyor box.

[0012] In this embodiment, two inclined limiting surfaces are formed within the limiting groove, and the two limiting surfaces form an obtuse angle; the two limiting surfaces are used to jointly press and limit the test tube.

[0013] In this embodiment, two inclined limiting surfaces are formed within the limiting groove, forming an obtuse angle, and the two limiting surfaces are used together to press and limit the test tube.

[0014] In summary, this utility model has the following beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This embodiment discloses a detection auxiliary component for online water quality detection, referring to... Figures 1-4 As shown, it includes a conveyor belt 1, which can move along a preset direction, such as a circulating conveyor or a reciprocating conveyor; several sets of test tube clamping mechanisms are installed on the conveyor belt 1, which can stably clamp the test tubes 3 and maintain the position accuracy of the test tubes 3, thereby facilitating the clamping of the test tubes by the robot arm and facilitating the implementation of automatic detection actions.

[0023] In this embodiment, the test tube clamping mechanism includes a transport box 2, a fixed frame 4, and a movable frame 5. The transport box 2 serves as the support for the entire test tube clamping mechanism. The bottom of the lower side of the transport box 2 is installed on the conveyor belt 1, which can connect the test tube clamping mechanism with the conveyor belt 1, and thus enable the test tube 3 to be moved and transported along with the conveyor belt 1.

[0024] The fixed frame 4 is vertically fixed inside the delivery box 2, and the movable frame 5 is set in the up-down direction. The middle section of the movable frame 5 is rotatably connected to the delivery box 2 through the rotating shaft 51, which is set in a roughly horizontal position. With the support of the rotating shaft 51, the movable frame 5 can tilt and swing, thereby limiting the position of the test tube 3.

[0025] Among them, a vertically oriented limiting groove 41 is provided on the side of the fixed frame 4 facing the movable frame 5. Specifically, two inclined limiting surfaces 411 are formed in the limiting groove 41. The two limiting surfaces 411 form an obtuse angle, approximately 120° laterally, and the two limiting surfaces 411 are used to jointly press and limit the test tube 3.

[0026] A pressure block 52 is fixedly installed at the upper end of the movable frame 5. When the test tube 3 is placed, the outer side of the test tube 3 will simultaneously contact the two limiting surfaces 411 of the limiting groove 41. The pressure block 52 applies pressure to the test tube 3, thereby ensuring that the test tube 3 remains in contact with the two limiting surfaces 411 and is thus kept in a vertical and stable position in the horizontal direction. When the robot arm clamps the test tube, the horizontal position of the test tube 3 will hardly deviate, thus ensuring effective clamping.

[0027] Furthermore, a vertically oriented limiting groove 53 is provided on the side of the pressure block 52 facing the fixing frame 4. The limiting groove 41 and the limiting groove 53 are arranged opposite to each other, and the limiting groove 41 and the limiting groove 53 are roughly symmetrically arranged, which can accommodate and limit the test tube 3 between the two.

[0028] Similarly, two inclined limiting surfaces 531 are formed within the limiting groove 53. The two limiting surfaces 531 form an obtuse angle and are used together to press and limit the test tube 3. Furthermore, when clamping and limiting the test tube 3, the two limiting surfaces 411 and 531 can be distributed in a roughly rhomboid shape, thereby effectively positioning the circular test tube 3 in the middle.

[0029] Furthermore, a bottom support block 54 is fixedly connected to the lower end of the movable frame 5. The bottom support block 54 protrudes towards the fixed frame 4 and tilts towards the fixed frame 4. During the downward placement of the test tube 3, the bottom of the test tube 3 will press against the upper part of the bottom support block 54, and the bottom support block 54 can press and support the bottom of the test tube 3.

[0030] The weight of test tube 3 will exert downward pressure on the bottom support block 54, which will then be converted through the inclined upper surface, thus transforming the downward pressure into the tilting and swaying force of the movable frame 5. The lower side of the movable frame 5 will sway outward, and correspondingly, the upper side of the movable frame 5 will sway towards the test tube 3. The pressure block 52 on the upper side of the movable frame 5 will come closer to the fixed frame 4. The limiting groove 53 of the pressure block 52 and the limiting groove 41 of the fixed frame 4 can position the test tube 3. At the same time, the tilting and swaying force of the upper side of the movable frame 5 will apply pressure to the test tube 3, so that the test tube 3 can abut against the two limiting surfaces 411 of the limiting groove 41, thus accurately positioning the test tube 3 in the horizontal direction.

[0031] Furthermore, a limiting recess 56 is formed on the upper surface of the bottom support block 54. The limiting recess 56 can roughly limit the bottom of the test tube 3 to maintain effective support for the test tube 3.

[0032] When the test tube 3 is not loaded, the lower side of the movable frame 5 needs to be tilted towards the fixed frame 4, while the upper side of the movable frame 5 is tilted away from the fixed frame 4, so as to form a larger opening on the upper side, allowing the test tube 3 to pass smoothly down.

[0033] Furthermore, a spring 55 is elastically pressed against the side of the movable frame 5 facing away from the fixed frame 4. The pressing position of the spring 55 is located below the rotating shaft 51. The elasticity of the spring 55 can effectively position the movable frame 5 in a tilted or swaying state. See the specific reference. Figure 4 As shown. One end of the spring 55 is connected to the movable frame 5, and the other end elastically abuts against the inner wall of the conveyor box 2.

[0034] In addition, the rotating shaft 51 is horizontally positioned, and the distance between the rotating shaft 51 and the pressure block 52 is greater than the distance between the rotating shaft 51 and the bottom support block 54. When the test tube 3 applies a downward force to the bottom support block 54 and the lower end of the movable frame 5, it can form a force-saving lever, thereby effectively assisting in pushing the movable frame 5 and effectively loading and positioning the test tube 3.

[0035] Furthermore, to improve the stability of the test tube 3 clamping, several sets of limiting ribs 42 are fixedly connected to the outside of the fixing frame 4 corresponding to the limiting groove 41. Each set of limiting ribs 42 has two ribs, and both limiting ribs 42 form an arc-shaped structure. The inner circumference of the limiting ribs 42 is slightly larger than the outer circumference of the test tube 3, thereby effectively limiting the stability of the test tube 3. Moreover, two sets of limiting ribs 42 are provided, distributed vertically, which can form two limiting structures in the vertical height direction, thereby effectively limiting the stability of the test tube 3.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
