Description

A sampling robot for environmental monitoring Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling robot for environmental testing. Background Technology

[0002] Environmental sampling is a fundamental step in environmental protection and governance. With the acceleration of industrialization and urbanization, environmental pollution problems are becoming increasingly complex and diverse, making it imperative to accurately grasp the state of environmental quality. Traditional manual sampling methods suffer from low efficiency, poor accuracy, and environmental limitations. To facilitate sampling and improve sampling efficiency, sampling personnel are usually equipped with robotic arms to extend the sampling range. Currently, existing robotic arms have a fixed length that cannot be adjusted, and the opening angle of the grippers at the front of the robotic arm cannot be adjusted either, resulting in many constraints during sampling. Based on this, this utility model is proposed. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An environmental sampling robot includes a handle for gripping, and further includes: a multi-section telescopic rod fixedly connected to the bottom of the handle, a transmission clamping rod rotatably connected to the bottom of the telescopic rod, and a clamping rod rotatably connected to the transmission clamping rod; a first sliding block slidably connected to the transmission clamping rod, a first connecting rod rotatably connected to the first sliding block, and the other end of the first connecting rod rotatably connected to the clamping rod; when the first sliding block slides, the angle between the clamping rod and the transmission clamping rod changes.

[0006] Preferably, a sliding rod is slidably connected to the bottom of the telescopic rod, a lifting link is fixedly connected to the sliding rod, a second link is rotatably connected to the lifting link, and the other end of the second link is rotatably connected to the transmission clamp rod.

[0007] Furthermore, a second compression spring is connected between the sliding rod and the telescopic rod, and a thread is fixedly connected to the telescopic rod. When the thread pulls the sliding rod upward, the transmission clamping rod rotates to clamp it.

[0008] Furthermore, a plurality of limiting rods are fixedly connected inside the handle, a turntable is rotatably connected to the handle, a rocker arm is fixedly connected to the turntable, the thread passes through the limiting rods and is fixedly connected to the turntable, and a clamping slider is slidably connected to the handle.

[0009] Furthermore, a ratchet gear is fixedly connected to the turntable, a limiting toothed plate is slidably connected to the handle, and a first compression spring is connected between the limiting toothed plate and the handle.

[0010] Furthermore, a through hole is provided on the limiting tooth plate, and a sliding inclined block is slidably connected to the handle, the sliding inclined block being slidably connected within the through hole.

[0011] Preferably, an adjusting bolt is rotatably connected to the transmission clamp rod, and the adjusting bolt is connected to the first sliding block by threads.

[0012] Preferably, the telescopic rod is threadedly connected with a locking bolt.

[0013] Compared with the prior art, this utility model provides a sampling robot for environmental monitoring, which has the following beneficial effects:

[0014] 1. The sampling robot for environmental monitoring is equipped with a telescopic rod, and a wire and a second compression spring are fixedly connected to the sliding rod. The two ends of the first connecting rod are rotatably connected to the first sliding block and the clamping rod, respectively.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technology.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: Referring to Figures 1-6, a sampling robot for environmental monitoring includes a handle 1 for gripping, and further includes: a multi-section telescopic rod 2 fixedly connected to the bottom of the handle 1; a transmission clamping rod 3 rotatably connected to the bottom of the telescopic rod 2; a clamping rod 31 rotatably connected to the transmission clamping rod 3; a first sliding block 33 slidably connected to the transmission clamping rod 3; a first connecting rod 34 rotatably connected to the first sliding block 33; the other end of the first connecting rod 34 rotatably connected to the clamping rod 31; when the first sliding block 33 slides, the angle between the clamping rod 31 and the transmission clamping rod 3 changes; a sliding rod 5 slidably connected to the bottom of the telescopic rod 2; a lifting connecting rod 52 fixedly connected to the sliding rod 5; a second connecting rod 53 rotatably connected to the lifting connecting rod 52; the other end of the second connecting rod 53 rotatably connected to the transmission clamping rod 3.

[0027] In this utility model, by setting a handle 1 and a telescopic rod 2, the length of the mechanical claw can be changed. The mechanical claw is divided into two parts: a transmission clamping rod 3 and a clamping rod 31. The transmission clamping rod 3 can drive the clamping rod 31 to clamp the sample by rotating. The clamping rod 31 can change the opening size by rotating, so as to adjust according to the size of the sample.

[0028] By setting a sliding rod 5 at the bottom of the telescopic rod 2, the sliding rod 5 drives the lifting link 52 to slide up and down. During the up and down movement, the lifting link 52 drives the second link 53 to rotate and pulls the transmission clamping rod 3 to rotate, thereby realizing the mechanical claw to grip the sample.

[0029] A first sliding block 33 is slidably connected to the transmission clamping rod 3. The two ends of the first connecting rod 34 are rotatably connected to the first sliding block 33 and the clamping rod 31, respectively. This allows the first sliding block 33 to rotate when it slides on the transmission clamping rod 3, which in turn causes the clamping rod 31 to rotate, thereby adjusting the size of the opening of the clamping rod 31.

[0030] Example 2: Referring to Figures 1-6, it is basically the same as Example 1, but with a further improvement: a second compression spring 51 is connected between the sliding rod 5 and the telescopic rod 2. A thread 6 is fixedly connected to the telescopic rod 2. When the thread 6 pulls the sliding rod 5 upward, the transmission clamping rod 3 rotates to clamp it. Multiple limiting rods 12 are fixedly connected inside the handle 1. A turntable 4 is rotatably connected to the handle 1. A rocker arm 41 is fixedly connected to the turntable 4. The thread 6 passes through the limiting rods 12 and is fixedly connected to the turntable 4. A clamping slide is slidably connected to the handle 1. Block 11, a ratchet gear 42 is fixedly connected to the turntable 4, a limiting toothed plate 43 is slidably connected to the handle 1, a first compression spring 44 is connected between the limiting toothed plate 43 and the handle 1, a through hole 431 is opened on the limiting toothed plate 43, a sliding inclined block 45 is slidably connected to the handle 1, the sliding inclined block 45 is slidably connected in the through hole 431, an adjusting bolt 32 is rotatably connected to the transmission clamping rod 3, the adjusting bolt 32 is connected to the first sliding block 33 by threads, and a locking bolt 21 is connected to the telescopic rod 2 by threads.

[0031] In this utility model, a wire 6 is fixedly connected to the sliding rod 5. By pulling the wire 6, the sliding rod 5 can be moved upward, thereby controlling the transmission clamping rod 3 to move closer to the center and clamp. A second compression spring 51 is connected between the bottom of the sliding rod 5 and the telescopic rod 2. Without external interference, the second compression spring 51 will pull the sliding rod 5 downward, thereby making the transmission clamping rod 3 in an open state.

[0032] The wire 6 is fixedly connected to the turntable 4. The turntable 4 can retract and extend the wire 6 by rotating. When the telescopic rod 2 extends or retracts, the wire 6 can always be kept taut by rotating the turntable 4. The wire 6 passes horizontally between the limit rods 12. When the user pushes the clamping slider 11 down, it will drive the taut wire 6 to pull the sliding rod 5 up, thereby realizing remote control of the mechanical claw's clamping.

[0033] A ratchet 42 is fixedly connected to the turntable 4. A first compression spring 44 is connected between the limiting tooth plate 43 and the handle 1. Under the action of the first compression spring 44, the limiting tooth plate 43 will always be in contact with the ratchet 42, so that the ratchet 42 and the turntable 4 can only rotate in one direction. The direction of the unidirectional rotation of the turntable 4 is to tighten the thread 6, so that the user can easily adjust the thread 6 to keep it in a taut state. When it is necessary to release the locking state of the limiting tooth plate 43, the sliding inclined block 45 can be slid. The sliding inclined block 45 pushes the limiting tooth plate 43 upward through the inclined surface, so that the limiting tooth plate 43 is disengaged from the ratchet 42.

[0034] The adjusting bolt 32 is rotatably connected to the transmission clamping rod 3. By rotating the adjusting bolt 32, the movement of the first sliding block 33 can be controlled, thereby controlling the angle between the clamping rod 31 and the transmission clamping rod 3.

[0035] By rotating the locking bolt 21 to apply pressure to the telescopic rod 2, the telescopic rod 2 can be fixed.

[0036] When using the device, the user first rotates the adjusting bolt 32 to adjust the opening angle of the clamping rod 31, then stretches the telescopic rod 2 to a suitable angle and rotates the locking bolt 21 to fix the telescopic rod 2. By rotating the rocker arm 41 to adjust the wire 6 to a taut state, the mechanical claw can be extended to the object to be clamped, and the clamping slider 11 can be pushed to complete the clamping.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
