Description

Technical Field

[0001] This utility model relates to the field of water sample testing technology, specifically a sampling and testing device for water supply and drainage. Background Technology

[0002] Drinking water quality is primarily considered in terms of its impact on human health. In addition to physical and chemical indicators, its water quality standards also include microbiological indicators. For industrial water, the consideration is whether it affects product quality or is likely to damage containers and pipes. In urban water supply and drainage projects, the water source needs to be screened in the early stages of the supply system. Water quality testing of the water source is a very important step, and the most important part of water quality testing is the sampling and testing of the water source.

[0003] While existing water sampling and testing equipment is equipped with high-precision sensors, enabling rapid detection of multiple parameters such as pH, turbidity, and heavy metals, providing accurate and reliable data; supports automated sampling and real-time analysis; and features a portable design for outdoor operation; and possesses data storage and wireless transmission capabilities, adapting to various scenarios and facilitating efficient water quality management, existing equipment is inconvenient for sampling water sources at different depths, requiring multiple samplings. This process is time-consuming and labor-intensive, reducing operational efficiency and increasing operating costs. Therefore, we provide a water supply and drainage sampling and testing device to address these issues. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a sampling and testing device for water supply and drainage. Through the cooperation of components such as the frame, sampling box, water inlet, underwater telescopic hydraulic cylinder, and sealing plate, it solves the problem that existing water source sampling and testing devices are not convenient for sampling water sources at different depths, requiring multiple samplings, which is time-consuming, labor-intensive, slows down operation efficiency, and increases operating costs.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling and testing device for water supply and drainage, comprising a traction mechanism, wherein the traction mechanism is provided with a sampling mechanism, wherein the sampling mechanism comprises a frame and an underwater telescopic hydraulic cylinder, wherein a counterweight is installed on the lower surface of the frame, and a set of equidistantly arranged sampling boxes are fixedly connected to the inner sidewall of the frame, wherein a water inlet hole is provided on the upper surface of the set of sampling boxes;

[0008] The output end of the underwater telescopic hydraulic cylinder is fixedly connected to a connecting frame. Two sets of symmetrical positioning plates are fixedly connected to the outer surface of the connecting frame. Two sets of equidistant connecting rods are fixedly connected to the connecting frame. Sealing plates are fixedly connected to the sides of the two sets of connecting rods that are close to each other. The lower surface of the sealing plate supports and seals the water inlet hole.

[0009] Furthermore, the underwater telescopic hydraulic cylinder is fixedly installed on the inner top wall of the frame, and the outer surfaces of the two sets of positioning plates are slidably connected to the inner sidewall of the frame.

[0010] Furthermore, the traction mechanism includes a float plate, the upper surface of which has a rope hole, and two mutually symmetrical support plates are fixedly connected to the upper surface of the float plate.

[0011] Furthermore, a winding drum is rotatably connected to one side of the two support plates that are close to each other, and a distance measuring rope is wound around the outer surface of the winding drum.

[0012] Furthermore, the end of the ranging rope away from the winding drum passes through the rope hole, and the end of the ranging rope away from the winding drum is fixedly connected to the upper surface of the float.

[0013] Furthermore, the right side of the right support plate of both sets of support plates has through holes, and a servo motor is fixedly installed on the right side of the right support plate of both sets of support plates.

[0014] Furthermore, the rotating shaft of the servo motor is fixedly connected to a rotating column, the left end of which passes through a through hole and is fixedly connected to the right end of the winding drum.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this sampling and testing equipment for water supply and drainage has the following advantages:

[0017] I. This water supply and drainage sampling and testing equipment, by controlling the retraction of an underwater telescopic hydraulic cylinder, drives the connecting frame to rise, simultaneously causing two sets of symmetrical positioning plates to slide upward inside the frame, and simultaneously causing multiple sets of symmetrical connecting rods to move upward, and multiple sealing plates to move upward, thereby releasing the seal of the water inlet. This allows for simultaneous sampling of water sources at different depths, achieving the purpose of this device to simultaneously sample water sources at different depths. It solves the problem that existing water source sampling and testing equipment is inconvenient to sample water sources at different depths, requiring multiple samplings, which is time-consuming, labor-intensive, slows down operation efficiency, and increases operating costs.

[0018] II. This water supply and drainage sampling and testing equipment controls the servo motor shaft to rotate counterclockwise, which in turn drives the rotating column to rotate in the same direction as the servo motor shaft. Simultaneously, it drives the winding drum to rotate in the same direction as the rotating column, thereby releasing the measuring rope wound around the outside of the winding drum. This allows the sampling mechanism to move downwards in the water, and the descent depth of the sampling mechanism can be observed through the scale on the measuring rope. This achieves the purpose of convenient and accurate placement of the sampling device, and solves the problem of insufficient sampling depth of the sampling device, resulting in insufficient accuracy of water source sampling and errors in the sampling and testing results.

[0025] 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.

[0026] The servo motor 107 and the underwater telescopic hydraulic cylinder 205 in this utility model are common electrical and hydraulic equipment in the prior art. This application will not elaborate on their models or internal structures.

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a sampling and testing device for water supply and drainage, including a traction mechanism 1, a sampling mechanism 2 provided on the traction mechanism 1, the sampling mechanism 2 including a frame 201 and an underwater telescopic hydraulic cylinder 205, a counterweight 202 installed on the lower surface of the frame 201, a set of equidistantly arranged sampling boxes 203 fixedly connected to the inner side wall of the frame 201, and a water inlet hole 204 opened on the upper surface of each set of sampling boxes 203, the output end of the underwater telescopic hydraulic cylinder 205 being fixedly connected to... A connecting frame 206 is connected, and two sets of symmetrical positioning plates 207 are fixedly connected to the outer surface of the connecting frame 206. Two sets of equidistant connecting rods 208 are fixedly connected to the connecting frame 206. Sealing plates 209 are fixedly connected to the side of the two sets of connecting rods 208 that are close to each other. The lower surface of the sealing plate 209 supports and seals the water inlet hole 204. The underwater telescopic hydraulic cylinder 205 is fixedly installed on the inner top wall of the frame 201. The outer surfaces of the two sets of positioning plates 207 are slidably connected to the inner side wall of the frame 201.

[0028] The spacing between a group of equally spaced sampling boxes 203 is determined according to actual needs. A sealing ring is provided at the contact point between the sealing plate 209 and the sampling box 203. The weight of the counterweight 202 is determined according to actual needs.

[0029] By controlling the underwater telescopic hydraulic cylinder 205 to retract, the connecting frame 206 is raised, which in turn causes two sets of symmetrical positioning plates 207 to slide upward inside the frame 201. Simultaneously, multiple sets of symmetrical connecting rods 208 are moved upward, and multiple sealing plates 209 are moved upward, thereby releasing the seal of the water inlet 204. This allows for simultaneous sampling of water sources at different depths, achieving the goal of simultaneous sampling of water sources at different depths. This solves the problem that existing water sampling and testing equipment is inconvenient for sampling water sources at different depths, requiring multiple samplings, which is time-consuming, labor-intensive, slows down operation, and increases operating costs.

[0030] The traction mechanism 1 includes a float 101. A rope hole 102 is provided on the upper surface of the float 101. Two mutually symmetrical support plates 103 are fixedly connected to the upper surface of the float 101. A winding drum 104 is rotatably connected to one side of the two support plates 103 that is close to each other. A distance measuring rope 105 is wound on the outer surface of the winding drum 104. The end of the distance measuring rope 105 away from the winding drum 104 passes through the rope hole 102. The end of the distance measuring rope 105 away from the winding drum 104 is fixedly connected to the upper surface of the float 101. A through hole 106 is provided on the right side of the right support plate 103 of the two sets of support plates 103. A servo motor 107 is fixedly installed on the right side of the right support plate 103 of the two sets of support plates 103. A rotating column 108 is fixedly connected to the rotating shaft of the servo motor 107. The left end of the rotating column 108 passes through the through hole 106 and is fixedly connected to the right end of the winding drum 104.

[0031] The measuring rope 105 here is a common tool in the prior art, and its structure and model will not be described in detail here. The end of the measuring rope 105 away from the winding drum 104 is fixedly connected to the center of the upper surface of the frame 201. The buoyancy of the float 101 here can meet the needs of this equipment.

[0032] By controlling the servo motor 107 to rotate counterclockwise, the rotating column 108 is driven to rotate in the same direction as the servo motor 107. At the same time, the winding drum 104 is driven to rotate in the same direction as the rotating column 108. This allows the measuring rope 105 wound around the outside of the winding drum 104 to be released, causing the sampling mechanism 2 to move downward in the water. The descent depth of the sampling mechanism 2 can be observed through the scale on the measuring rope 105. This achieves the purpose of convenient and accurate arrangement of the sampling device, and solves the problem of insufficient sampling depth of the sampling device, resulting in insufficient accuracy of water source sampling and errors in the sampling and testing results.

[0033] Working principle: In use, the float 101 is first placed on the designated water surface. Then, the shaft of the servo motor 107 is controlled to rotate counterclockwise, which in turn drives the rotating column 108 to rotate in the same direction as the shaft of the servo motor 107. At the same time, the winding drum 104 rotates in the same direction as the rotating column 108, thereby releasing the measuring rope 105 wound on the outside of the winding drum 104. This allows the sampling mechanism 2 to move downward in the water, and the descent depth of the sampling mechanism 2 can be observed through the scale on the measuring rope 105, thus achieving the purpose of convenient and accurate placement of the sampling device. By controlling the underwater telescopic hydraulic cylinder 205 to retract, the connecting frame 206 is driven to rise, which in turn drives two sets of mutually symmetrical positioning plates 207 to slide upward inside the frame 201. Simultaneously, multiple sets of mutually symmetrical connecting rods 208 are driven to move upward, and multiple sealing plates 209 are driven to move upward, thereby releasing the seal of the water inlet 204. This allows for simultaneous sampling of water sources at different depths, achieving the purpose of simultaneous sampling of water sources at different depths.
