[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 , the embodiments of the present utility model include:

[0026] A contaminated site driving and protection device for an automated sampler comprises a frame mechanism, a support mechanism, and a position sensor for detecting pipeline height and width. The position sensor is disposed on the frame mechanism, and the support mechanism is movably connected to the bottom of the frame mechanism to cooperate with the frame mechanism to cover a pipeline in the contaminated site and adjust the position and angle of the frame body in real time, so that the automated sampler can be driven from the frame mechanism. This not only prevents the automated sampler from being interfered with by pipelines in the site, thus facilitating driving and improving work efficiency, but also prevents the sampler from directly contacting and pressing the pipeline, thereby protecting the pipeline.

[0027] More preferably, the position sensor may be an infrared sensor, a laser sensor or a CCD.

[0028] Further preferably, the driving and protection device also includes a controller, which is connected to the frame mechanism, the supporting mechanism and the position sensor respectively to control the movement of telescoping, lifting and translation.

[0029] Further preferably, the bottom of the frame mechanism is provided with more than or equal to 4 groups of support mechanisms, each group of support mechanisms can independently control the movement, or two groups of support mechanisms in relative positions can maintain synchronous movement, which can be adjusted and set according to the size specifications of the frame body.

[0030] Further preferably, a guide limit seat 3 is fixedly or movably provided on the top surface of the frame body to facilitate the upward and downward movement of the sampler.

[0031] The frame mechanism 1 includes a first frame 11 , a second frame 12 , an extended protrusion 13 , a retracted recess 14 , a telescopic connecting frame 15 , a telescopic guide 16 , and a telescopic driving device 17 .

[0032] The first frame is provided with a plurality of retracted recesses at intervals, and one or both sides of the second frame are provided with a plurality of extended protrusions at intervals. The retracted recesses correspond to the extended protrusions one by one and are movably connected to facilitate the extension and retraction of the frame mechanism.

[0033] The telescopic connecting frame is arranged on the bottom surface of the extended protrusion, and the telescopic guide part is arranged on the bottom surface of the first frame. The telescopic connecting frame is movably connected to the telescopic guide part to perform telescopic guidance and make the frame evenly stressed, thereby maintaining the synchronous movement of the entire frame and preventing deformation. The telescopic driving device is respectively connected to the first frame and the second frame to drive the first frame and the second frame to telescopic movement according to the diameter of the pipeline.

[0034] When the frame mechanism extends outward, the first frame and the second frame move away from and extend outward, increasing the length of the frame mechanism. The gap between the first frame and the second frame is supplemented by the extended protrusion to improve the flatness and load-bearing capacity of the frame mechanism, making it easier for the automated sampler to move on the frame mechanism and preventing the sampler from sinking and getting stuck in the frame mechanism or the frame mechanism from being deformed and damaged.

[0035] When the frame mechanism retracts inward, the first frame and the second frame approach each other. At this time, the extended protrusion is inserted into the retracted recess, which can effectively shorten the length of the frame mechanism, minimize its own volume, and expand its scope of application.

[0036] Further preferably, one or both sides of the first frame are provided with retracted recesses.

[0037] Further preferably, the second frame and the extended protrusion are an integrated structure.

[0038] Further preferably, the telescopic drive device can adopt a cylinder, a motor screw module, a linear module, etc.

[0039] For example, when using a pneumatic cylinder, the cylinder can be mounted on the bottom surface of the first frame, with its output end connected to the second frame or the telescopic connecting frame to drive the frame to extend and retract. When using a motor screw module, the ends of the screw in the screw are connected to the bearing seats on the first and second frames respectively, and the nut on the screw is connected to the telescopic connecting frame.

[0040] Further preferably, an arc-shaped plug-in guide surface is provided on the outer end of the extended protrusion, and an plug-in guide inclined surface is provided at the opening on the outer side of the retracted recess, so as to facilitate the smoothness and accuracy of the movement and connection of the extended protrusion and the retracted recess, and prevent the problem of inaccurate alignment or jamming during the retraction process.

[0041] Further preferably, the opening of the retracted recess and the side wall of the outer end of the extended protrusion are provided with mutually cooperating limit blocks to prevent the extended protrusion from escaping from the retracted recess, thereby improving the stability of the device.

[0042] The supporting mechanism includes a translation plate 20 , a translation guide portion 21 , a translation drive device 25 , a lifting plate 22 , a lifting drive device 27 , a leg mounting frame 23 , and a supporting leg 24 .

[0043] The supporting legs can be rotatably set on the leg mounting frame, the leg mounting frame is set on the translation plate, the translation guide part and the translation drive device are set on the bottom surface of the lifting plate, the top of the translation plate is movably connected to the translation guide part, and the translation drive device drives the supporting legs to move back and forth through the translation plate to adjust the position and spacing of the supporting legs. The supporting legs can clamp the side walls of the pipeline, which can improve the stability of the driving and protection device, and can also protect the pipeline more effectively. The lifting drive device is set on the bottom surface of the frame mechanism, and its output end is connected to the lifting plate to drive the lifting plate and the components thereon to perform lifting movements as a whole, thereby adjusting the height of the frame mechanism according to the height of the pipeline.

[0044] Further preferably, a rotation drive device 26 is provided on the leg mounting frame, whose output shaft is connected to the support leg to drive the support leg to rotate, thereby realizing horizontal folding or vertical unfolding of the support leg. Among them, the rotation drive device can adopt a rotating motor, a motor gear module and other devices.

[0045] Further preferably, the lifting drive device can be extended and installed within the guide limit seat, specifically using a lifting cylinder, a motor-paper-wheel rack module, a linear module, or other devices. When using a lifting cylinder, the lifting cylinder is installed in the installation slot of the lifting plate, with its output end connected to the leg mounting bracket with its downward facing end. The lifting cylinder and the lifting plate are rotatably connected.

[0046] Further preferably, the translation drive device can adopt a translation cylinder, a motor screw module, a linear module, etc.

[0047] Further preferably, the supporting leg is rotatably connected to the leg mounting frame via a rotating shaft, and a limit block for limiting the rotation angle of the supporting leg is provided on the leg mounting frame.

[0048] Further preferably, the supporting legs are L-shaped to increase the supporting force and improve stability.

[0049] The working principle includes:

[0050] When in use, the mechanism can be placed next to an obstacle such as a pipeline. The position sensor senses or detects the height and width of the pipeline. The controller first starts the rotation drive device based on the detection information. The rotation drive device rotates the support legs to a vertical state to support the frame mechanism, and then the lifting drive device is started to lift the frame mechanism to a height exceeding the pipeline; the telescopic drive device is started to drive the frame mechanism to extend. At this time, the support legs on the frame that are extended to the top of the pipeline are folded to avoid it until these support legs move to the other side of the pipeline and then rotate open; the translation drive device is started and drives multiple groups of support mechanisms close to the pipeline to move inward to clamp the pipeline. The outer support mechanisms can choose not to move or to perform adaptive translation according to the preset maximum spacing threshold between the support mechanisms until the entire device is covered on the pipeline or obstacle;

[0051] Alternatively, when in use, the device is directly placed on an obstacle, and the position sensor senses or detects the height and width of the pipeline. The controller first activates the telescopic drive device to adjust the length of the frame mechanism based on the detection information, and then the lifting drive device and the rotation drive device are activated to open the support legs and adjust their heights to support the frame mechanism. Then the translation drive device is activated and drives the multiple groups of support mechanisms close to the pipeline to move inward to clamp the pipeline. The outer support mechanisms can choose not to move or to perform adaptive translation according to the preset maximum spacing threshold between the support mechanisms until the entire device is covered on the pipeline or obstacle;

[0052] When the position sensor detects that the automated sampler moves to the side of this device, the support mechanism close to the sampler side will drop first, so that the frame mechanism forms a slope, which is convenient for the sampler to move onto the frame mechanism; when the sampler moves to the middle of the frame mechanism, the support mechanism that was originally dropped rises, and the support mechanism on the other side drops, which is convenient for the sampler to come down.

[0053] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
