Description

Technical Field

[0001] The present invention relates to the technical field of sewage sampling equipment, and particularly relates to a remote sampling device for sewage detection. Background Art

[0002] Most of the existing sampling methods for sewage detection implement the sampling operation through a water sampler. During the operation, manual operation of the water sampler is required. However, this sampling method is only applicable to a safe water environment. If sampling operations need to be carried out at different points, manual repeated operation of the water sampler is required, which takes a long time and is prone to certain errors during the operation of the water sampler. At the same time, if the terrain of the water bank is steep, there are certain safety hazards in using the water sampler to implement the sampling operation, and the difficulty of the sewage sampling work also increases, affecting the efficiency of the sampling work. Therefore, the present application provides a remote sampling device for sewage detection to meet the requirements. Summary of the Invention

[0003] In view of the above problems, the present application provides a remote sampling device for sewage detection.

[0004] To achieve the above object, the present application provides the following technical solution: A remote sampling device for sewage detection includes a frame. A positioning platform is provided at the top of the frame. An extension arm capable of transverse movement is provided on the positioning platform. The end of the extension arm extends out of the positioning platform, and a positioning support distributed downward is provided at the end of the extension arm extending out of the positioning platform.

[0005] A traction arm capable of ascending and descending movement is provided on the positioning support. A water sampler capable of ascending and descending synchronously with the traction arm is provided at the bottom end of the traction arm. As the traction arm descends, the water sampler immerses into the sewage from above the sewage.

[0006] A plurality of equally spaced follower rods are provided on the outer side of the water sampler along a circumferential trajectory. The plurality of follower rods can rotate synchronously, and each follower rod has a U-shaped structure. The water sampler is distributed in the relative space between the two symmetric legs of the follower rod. When the plurality of follower rods rotate synchronously, the two symmetric legs of the follower rod can synchronously abut against or move away from both ends of the water sampler.

[0007] Further, the extension arm has a U-shaped structure, and a first linkage rack capable of moving synchronously with the extension arm is provided inside one of the arms of the extension arm. A first electric gear is meshingly connected to the first linkage rack, and the first electric gear is fixedly installed above the positioning platform.

[0008] Two transverse guide rails adapted to the two arms of the extension arm are provided on the surface of the positioning platform. When the first electric gear meshingly moves the first linkage rack, the extension arm moves synchronously along the distribution direction of the transverse guide rails.

[0009] Furthermore, two parallel vertical guide rails are provided on one side of the positioning bracket close to the frame. The traction arm is in a rectangular structure, and the two longer arms of the traction arm are respectively slidably connected to the two vertical guide rails.

[0010] A second linkage rack is provided on one side of the traction arm close to the frame, and a second electric gear is meshedly connected to the second linkage rack. The second electric gear is arranged on the end of the extension arm through a carrier.

[0011] Furthermore, the bottom end of the traction arm is provided with a connecting platform that can rise and fall synchronously with the traction arm. The bottom end of the connecting platform is provided with four positioning rods. The bottom ends of the four positioning rods are connected by a limit bracket. The water sampler is located in the relative space of the four positioning rods, and the water sampler passes through the limit bracket.

[0012] Furthermore, the limit support is provided with a rotatable inner gear ring, and the inner side of the inner gear ring is engaged with a plurality of guide gears equidistantly distributed along a circular trajectory, and a plurality of follower rods are respectively installed on the central axis position of the guide gears. When the inner gear ring engages with the plurality of guide gears and rotates synchronously, the plurality of follower rods rotate synchronously, and the two symmetrical legs of the follower rods can synchronously abut or move away from the two ends of the water sampler.

[0013] Furthermore, the two symmetrical legs of the follower rod are provided with limit columns perpendicular thereto. When the two symmetrical legs of the follower rod synchronously abut against the two ends of the water sampler, the two groups of limit columns symmetrically distributed from top to bottom abut against the side surface of the water sampler.

[0014] Furthermore, a bracket is provided at the bottom end of the position-limiting bracket, the guide gears are rotatably mounted on the bracket, and the follower rods pass through the bracket.

[0015] Furthermore, an outer gear ring which can rotate synchronously with the inner gear ring is fixed to the top of the inner gear ring through a connecting plate, and a driving gear is meshedly connected to the outer side of the outer gear ring, and a control handle which is coaxially distributed with the driving gear is provided on the driving gear.

[0016] Furthermore, a support plate is provided outside the limit support, and the control handle is installed on the support plate.

[0017] In summary, the technical effects and advantages of the present invention are as follows:

[0018] 1. The present invention enables the water sampler to perform water sampling operations at different locations according to sampling requirements. During the sampling process, the movement of the water sampler can be remotely controlled at the shore of the water area. Manual sampling is required throughout the process. It is suitable for working environments where manual sampling operations are difficult to implement. It has the advantage of being able to sample remotely, thereby improving the safety and portability of sewage sample collection.

[0019] 2. The present invention features an adjustable follower rod that limits the position of the water sampler, preventing it from falling during descent to collect water and ascent to transport water samples, thus ensuring safe water collection. When the water collection operation is completed, the follower rod can be adjusted in angle to leave space for the water sampler. This reduces the time required to locate and remove each point outside the water sampler, improving portability during installation and removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Refer to Figure 1 、 Figure 2 A remote sampling device for sewage detection shown. A remote sampling device for sewage detection includes a frame 1. A positioning table 2 is provided at the top of the frame 1. During the actual application process of the remote sampling device for sewage detection, both the frame 1 and the positioning table 2 are arranged on the shore of the water area.

[0031] In order to be able to smoothly perform sampling operations inside the water area, in the present invention, an extensible arm 3 capable of transverse movement is provided on the positioning table 2. The end of the extensible arm 3 extends out of the positioning table 2, and a positioning support 4 distributed downward is provided at the end of the extensible arm 3 extending out of the positioning table 2. A traction arm 5 capable of ascending and descending movement is provided on the positioning support 4. A water sampler 6 capable of ascending and descending synchronously with it is provided at the bottom end of the traction arm 5. As the traction arm 5 descends, the water sampler 6 immerses into the sewage from above the sewage. During the entire sampling process, the movement of the water sampler 6 can be remotely controlled while located on the shore of the water area to perform the sampling operation.

[0032] Furthermore, a plurality of equally spaced follow-up rods 11 are provided along the circumferential trajectory on the outer side of the water sampler 6. The plurality of follow-up rods 11 can rotate synchronously, and each follow-up rod 11 has a U-shaped structure. The water sampler 6 is distributed in the relative space between the two symmetric legs of the follow-up rod 11. When the plurality of follow-up rods 11 rotate synchronously, the two symmetric legs of the follow-up rod 11 can synchronously abut against or move away from both ends of the water sampler 6.

[0033] Before performing the sewage sampling work, the two symmetric legs of the follow-up rod 11 abut against both ends of the water sampler 6 to limit the water sampler 6 and prevent the water sampler 6 from falling during the sampling process. When the sewage sampling work is completed, the two symmetric legs of the follow-up rod 11 synchronously move away from both ends of the water sampler 6, leaving a space where the water sampler 6 can be taken.

[0034] As Figure 3 shown, the extensible arm 3 has a U-shaped structure, and a linkage rack one 31 capable of moving synchronously with it is provided inside one of the arms of the extensible arm 3. An electric gear one 32 is meshed and connected to the linkage rack one 31. The electric gear one 32 is fixedly installed above the positioning table 2.

[0035] Positioning platform 2 is equipped with two transverse guide rails 33, each corresponding to the two arms of extension arm 3. When motorized gear 1 32 engages rack 1 31 and moves, extension arm 3 moves synchronously along the distribution direction of transverse guide rails 33. The movement of extension arm 3 causes positioning support 4 and traction arm 5 to move synchronously with it, allowing water sampler 6 to be moved to a designated location for sampling of sewage at that location.

[0036] Therefore, based on the combined arrangement of the extension arm 3, the positioning support 4, the traction arm 5 and the water sampler 6, the water sampler 6 can perform water sampling operations at different locations according to sampling requirements. During the sampling process, the movement of the water sampler 6 can be remotely controlled at the shore of the water area. Manual sampling is required throughout the process, which is suitable for working environments where manual sampling operations are difficult to implement. It has the advantage of being able to sample remotely, thereby improving the safety and portability of sewage sample collection.

[0037] like Figure 4 As shown, two parallel vertical guide rails 41 are provided on one side of the positioning bracket 4 close to the frame 1 , the traction arm 5 is a rectangular structure, and the two longer arms of the traction arm 5 are slidably connected to the two vertical guide rails 41 respectively.

[0038] On the side of the traction arm 5 near the frame 1, a linkage rack 2 51 is installed. This linkage rack 51 is meshed with a motorized gear 2 34, which is mounted on the end of the extension arm 3 via a carrier. When motorized gear 2 34 rotates, the meshing force between it and linkage rack 2 51 causes the traction arm 5 to rise and fall. When the traction arm 5 descends, the water sampler 6 descends to collect water. When the traction arm 5 ascends, the water sampler 6 ascends accordingly, transporting the collected water sample.

[0039] like Figure 5 As shown, the bottom end of the traction arm 5 is provided with a connecting platform 52 which can rise and fall synchronously with the traction arm 5. The bottom end of the connecting platform 52 is provided with four positioning rods 53. The bottom ends of the four positioning rods 53 are connected by a limit bracket 7. The water sampler 6 is located in the relative space of the four positioning rods 53, and the water sampler 6 passes through the limit bracket 7.

[0040] As the traction arm 5 descends, the four positioning rods 53 are immersed in the sewage. Simultaneously, the water sampler 6 also immerses into the sewage, allowing for sewage sampling. The water sampler 6 in the technical solution of the present invention is a conventional organic glass water sampler. This organic glass water sampler achieves stratified sampling through gravity sinking and an automatic closing mechanism. As the water sampler 6 descends, the bottom water inlet automatically opens, allowing the water sample to enter the barrel. When the water sampler 6 is lifted, the upper and lower covers close due to water pressure, preventing the water sample from mixing.

[0041] like Figure 6 、 Figure 7As shown, the limit bracket 7 is provided with a rotatable inner ring gear 8, the inner side of which is meshed with multiple guide gears 10 distributed evenly along a circumferential trajectory. Multiple follower rods 11 are respectively mounted on the central axis of the guide gears 10. When the inner ring gear 8 rotates, its inner teeth mesh with the multiple guide gears 10 to rotate synchronously and in the same direction, thereby causing the multiple follower rods 11 to rotate synchronously with it. The two symmetrical legs of the follower rods 11 can synchronously abut or move away from the two ends of the water sampler 6.

[0042] When the two symmetrical legs of the follower rod 11 abut the ends of the water sampler 6, the sampler 6 is positioned, preventing it from falling during the process of descending to collect water and ascending to transport the water sample, thus ensuring the safety of the water collection operation. When the water collection operation is completed, the internal gear ring 8 engages the multiple guide gears 10 and rotates in the opposite direction. The force of this rotation causes the two symmetrical legs of the follower rod 11 to synchronously move away from the ends of the water sampler 6, leaving space for the sampler 6 to be removed. The staff can then remove the sampler 6 to perform further operations such as transferring and testing the water sample.

[0043] Example 2: Based on Example 1, Figure 6 As shown, the two symmetrical legs of the follower rod 11 are provided with limit columns 12 perpendicular to them. When the two symmetrical legs of the follower rod 11 synchronously abut against the two ends of the water sampler 6, the two groups of limit columns 12 symmetrically distributed from top to bottom abut against the side surface of the water sampler 6.

[0044] The setting of the limiting column 12 can clamp the water sampler 6 from the side, effectively preventing the water sampler 6 from shaking during the process of descending to collect water and ascending to transport water samples, further improving the stability of the water sampler 6 during the sampling operation, and effectively avoiding the splashing and overflow of water samples, thereby protecting the water samples.

[0045] When the multiple follower rods 11 rotate synchronously and the two symmetrical legs of the follower rod 11 move away from the two ends of the water sampler 6, the limit column 12 also moves away from the side surface of the water sampler 6 synchronously, leaving space for convenient transfer of the water sampler 6.

[0046] like Figure 7 As shown, in order to maintain the stability of the guide gear 10 and the follower rod 11, on the basis of the installation of the inner gear ring 8 and the limit bracket 7, a bracket 71 is also provided at the bottom end of the limit bracket 7. The guide gear 10 is rotatably installed with the bracket 71, and the follower rod 11 passes through the bracket 71.

[0047] like Figure 7As shown, in the present invention, an outer gear ring 9 is fixed to the top of the inner gear ring 8 via a connecting plate, which can rotate synchronously with it. The outer side of the outer gear ring 9 is meshed with a drive gear 91, and a control handle 92 is provided on the drive gear 91, which is coaxially arranged with the drive gear 91. During the installation and removal of the water sampler 6, operating the control handle 92 can control the rotation of the drive gear 91, thereby driving the rotation of the inner gear ring 8.

[0048] As the internal gear ring 8 rotates, it drives the three guide gears 10 to rotate synchronously, thereby achieving the purpose of synchronously controlling the movement of the three follower rods 11. This allows the two symmetrical legs of the follower rods 11 to synchronously abut or move away from the ends of the water sampler 6, facilitating the installation and removal of the water sampler 6. This reduces the time required to locate and remove each point on the outside of the water sampler 6, improving the portability during installation and removal of the water sampler 6.

[0049] like Figure 7 As shown, in order to maintain the stability of the control handle 92 and the driving gear 91 connected thereto, a support plate 72 is provided outside the limit support 7 , and the control handle 92 is mounted on the support plate 72 , and the control handle 92 can be operated from below the support plate 72 .

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
