Description

Technical Field

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

[0002] Wastewater sampling is an important part of the wastewater treatment process to ensure that the wastewater treatment effect and effluent quality meet relevant standards, protect the environment and public health. Its main purpose is to monitor and evaluate the quality of wastewater. Through sampling, the nature and composition of wastewater can be determined, and the concentration and quality of pollutants can be analyzed to evaluate the treatment effect.

[0003] However, in the existing technology, the existing sewage collection cup is equipped with a telescopic rod. After the telescopic rod is manually extended so that the testing personnel can send the sewage collection cup to a distant water area to collect sewage samples, it is usually not convenient to manually retract the telescopic rod after the sewage collection cup is sent to a distant water area to collect sewage samples. Since the sewage collection cup is far away from the person, it is not convenient to stably send the sewage collection cup at a distance back to the shore. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: typically, after manually extending the telescopic rod and holding its end to send the sewage collection cup to a distant water location to collect sewage samples, it is inconvenient to manually retract the telescopic rod. Since the sewage collection cup is far from the person, it is not convenient to stably send the sewage collection cup, which is located at a distance, back to the shore.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sewage treatment sampling device, comprising a sewage collection cup, mounting frames rotatably connected to both sides of the sewage collection cup, and a movable rod fixed to one end of the mounting frame, a hollow storage rod movably inserted into the outer surface of the movable rod, a disc clamp fixedly connected to one end of the movable rod, the disc clamp movably connected in the hollow storage rod and engaging with the front and rear ends of its hollow cavity, a connecting block fixed to one end of the hollow storage rod, a handle fixed to one side of the connecting block, a pull line fixed to one side surface of the disc clamp, the pull line penetrating and connecting to the end of the hollow storage rod, a take-up shaft rotatably connected to one side surface of the connecting block, the take-up shaft being fixedly connected to one end of the pull line, and a rotating handle fixedly connected to one side edge surface of the take-up shaft.

[0006] In a preferred embodiment, scale lines are provided on both sides of the sewage collection cup, and the sewage collection cup is made of transparent material.

[0007] In a preferred embodiment, a first steering shaft is rotatably connected to the hollow cavity surface of the hollow storage rod near its end position. A bracket is fixedly connected to one edge of the connecting block, and a second steering shaft is rotatably connected to the bracket.

[0008] In a preferred embodiment, sliders are fixedly connected to both the upper and lower ends of the disc holder, and the sliders are slidably connected to the hollow storage rod.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] In this invention, after the wastewater collection cup has collected wastewater samples from a distant water source, the winding shaft is rotated by hand by cranking the rotating handle. As the winding shaft rotates, the pulling line gradually winds up on it, causing the pulling line to pull on the disc clamp and the movable rod. This causes the movable rod to gradually move and retract into the hollow storage rod, moving the wastewater collection cup from a distant water source to a closer water source, making it easy to stably return it to the shore.

[0017] 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.

[0018] Example 1

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a sampling device for sewage treatment, including a sewage collection cup 1. Mounting frames 3 are rotatably connected to both sides of the sewage collection cup 1, and a movable rod 4 is fixed to one end of the mounting frame 3. With the help of the mounting frame 3, the sewage collection cup 1 can be easily rotated and mounted to one end of the movable rod 4, allowing the sewage collection cup 1 to tilt and pour out the sewage sample. A hollow receiving rod 5 is movably inserted into the outer surface of the movable rod 4. A disc retainer 6 is fixedly connected to one end of the movable rod 4, and the disc retainer 6 is movably connected to the hollow receiving rod 5 and engages with the front and rear ends of its hollow cavity. When the movable rod 4 is fully retracted or fully extended outward in the hollow receiving rod 5, the disc retainer 6 engages with the hollow receiving rod 5, improving the stability of the movable rod 4 after extension and retraction. One end of the hollow storage rod 5 is fixed with a connecting block 7, and a handle 8 is fixed on one side of the connecting block 7. The handle 8 makes it easy to hold the hollow storage rod 5 at the end. A pull line 9 is fixed on one side surface of the disc clip 6, and the pull line 9 passes through and connects to the end of the hollow storage rod 5. A take-up shaft 10 is rotatably mounted on one side surface of the connecting block 7, and the take-up shaft 10 is fixedly connected to one end of the pull line 9. A rotating handle 11 is fixedly connected to one side edge surface of the take-up shaft 10. By shaking the rotating handle 11 by hand, the take-up shaft 10 is rotated. When the take-up shaft 10 rotates, it causes the pull line 9 to gradually wind up on it, thereby causing the pull line 9 to pull the disc clip 6 and the movable rod 4, causing the movable rod 4 to gradually move and retract into the interior of the hollow storage rod 5, and moving the sewage collection cup 1 from the far water to the near water, so that it can be stably sent back to the shore.

[0020] Example 2

[0021] like Figure 1-4As shown, scale lines 2 are provided on both sides of the sewage collection cup 1, and the sewage collection cup 1 is made of transparent material. The scale lines 2 make it easy to know the specific volume of sewage sample collected in the sewage collection cup 1. A first steering shaft 12 is rotatably connected to the hollow cavity surface of the hollow storage rod 5 near its end. A bracket is fixedly connected to one edge of the connecting block 7, and a second steering shaft 13 is rotatably connected to the bracket. With the help of the first steering shaft 12 and the second steering shaft 13, the pulling line 9 is turned at a right angle, allowing it to be pulled... During the winding and pulling process of the rotating take-up shaft 10, the friction generated by its contact with the through hole at the end of the hollow storage rod 5 and the edge of the connecting block 7 is reduced, thereby reducing the damage to the pulling line 9 caused by friction and improving the service life of the pulling line 9. The upper and lower ends of the disc clamp 6 are fixedly connected to the sliders 14, and the sliders 14 are slidably connected to the hollow storage rod 5. With the help of the sliders 14, the moving rod 4 and the disc clamp 6 are effectively prevented from rotating relative to the hollow storage rod 5, so that the disc clamp 6 can be smoothly engaged with the hollow storage rod 5.

[0022] Working principle:

[0023] like Figure 1-4 As shown, in use, when the movable rod 4 is extended outwards towards the hollow storage rod 5, the user holds the handle 8 and, from the shore, uses the movable rod 4 and the hollow storage rod 5 to deliver the sewage collection cup 1 to the distant water area, scooping the sewage from that area into the sewage collection cup 1, thus completing the sample collection of the sewage from the distant water area. When it is necessary to return the sewage collection cup 1 to the shore, the user manually cranks the rotating handle 11 to rotate the take-up shaft 10. The rotating take-up shaft 10 winds up and pulls the pull line 9. When the pull line 9 is being pulled, it will drive the rotation of the first steering shaft 12 and the second steering shaft 13, reducing the distance between the pull line 9 and the hollow storage rod 5. The sliding friction at the through hole at the end of the receiving rod 5 and the edge of the connecting block 7, along with the pulling line 9 being pulled, will also cause the disc clamp 6, the slider 14 and the movable rod 4 to move, so that the disc clamp 6 is released from the front end of the hollow cavity of the hollow receiving rod 5, and the movable rod 4 gradually moves and retracts into the interior of the hollow receiving rod 5. When the movable rod 4 is completely retracted into the interior of the hollow receiving rod 5, the disc clamp 6 is engaged with the rear end of the hollow cavity of the hollow receiving rod 5, and the winding shaft 10 stops rotating as it winds up the pulling line 9. At this time, due to the retraction of the movable rod 4, the sewage collection cup 1 is moved from the far water to the near water, making it convenient to stably send the sewage collection cup 1 back to the shore.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
