Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, and particularly relates to a multi-layer water quality separation sampling structure for environmental detection. Background Art

[0002] Water environment monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. The method for monitoring water body pollution is usually to sample water layers at different depths of the water body and conduct various tests and comparisons to timely understand the changes in the water body system and obtain various data;

[0003] In the prior art, when evaluating the water quality of a region, it is necessary to sample the water quality of the region. However, the existing sampling devices cannot be adjusted in depth. At the same time, during extraction, the collection bottle needs to be frequently collected, which easily affects the collection progress. Therefore, the detection speed is reduced and the labor intensity of the operator is increased. For this reason, a multi-layer water quality separation sampling structure for environmental detection is proposed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a multi-layer water quality separation sampling structure for environmental detection, which can solve the problems in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: A multi-layer water quality separation sampling structure for environmental detection, including a vehicle body in a "C" shape. A self-locking universal wheel is arranged at the lower end of the vehicle body. A telescopic plate is slidably connected to the vehicle body. An installation groove is opened on the telescopic plate. A winch is rotatably connected inside the installation groove. One side of the telescopic plate is fixedly connected with a servo motor. The output end of the servo motor is fixedly connected with the winch. A suspension rope is wound around the winch. One end of the suspension rope far from the winch is fixedly connected with a counterweight. A water sampling ball is slidably connected to the suspension rope. An adjusting mechanism is arranged on the water sampling ball. A water outlet pipe is fixedly connected to the water sampling ball. An automatic control valve is fixedly connected to the water sampling ball. A sealing cover is arranged on the water outlet pipe.

[0006] Preferably, the adjusting mechanism includes a connecting block in a square frame shape. The connecting block is fixedly connected to the water sampling ball. The suspension rope passes through the connecting block. Two inserting rods are slidably connected to the side of the connecting block far from the water sampling ball. Two fixing cones are respectively slidably connected to both sides of the connecting block. Two built-in holes are opened on the inner wall of the connecting block. The fixing cones are respectively slidably connected inside the built-in holes. A fixing hole is opened on the fixing cone. The inserting rod is movably connected inside the fixing hole. A spring is movably sleeved on the inserting rod. Both ends of the spring are respectively fixedly connected to the surface of the inserting rod and the connecting block. The end of the fixing cone close to the inserting rod is conical. The end of the inserting rod close to the fixing cone is arc-shaped.

[0007] Preferably, the interior of the water collection ball is a hollow structure and has a hollow tube, both ends of the hollow tube pass through the water collection ball, the lifting rope is located inside the hollow tube, the interior of the vehicle body is fixedly connected with a telescopic rod, and the output end of the telescopic rod is fixedly connected to the telescopic plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] (1) The multi-layer water quality separation sampling structure for environmental testing can move the position of the water sampling ball on the hanging rope and the spacing between multiple water sampling balls according to needs when it is necessary to collect water at different depths. At this time, when the water sampling ball moves to the specified position, it pushes the fixed cone, and the fixed cone penetrates the hanging rope and is inserted into the interior of the built-in hole. Since one end of the insertion rod is arc-shaped, the conical end of the fixed cone applies pressure to the insertion rod, and the insertion rod moves upward, thereby causing the spring to be stressed. When the fixed hole moves to the position where the insertion rod is located, the spring drives the insertion rod to reset, so that the insertion rod is inserted into the interior of the fixed hole, thereby completing the fixation of the fixed cone. At this time, under the restriction of the fixed cone, the position of the water sampling ball is fixed, thereby completing the adjustment of the water sampling ball, so that the device can collect water at different depths at the same time.

[0010] (2) The multi-layer water quality separation sampling structure for environmental testing and the setting of the counterweight block ensure that the water sampling ball can enter water of different depths, thereby completing the water sampling of different water layers and avoiding the floating phenomenon of the water sampling ball, thereby ensuring the normal collection of the water body.

Detailed implementation manners

[0019] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0020] Please refer to Figure 1-6 , the present invention provides a technical solution: a multi-layer water quality separation sampling structure for environmental detection, including a vehicle body 1 in a "C" shape. A self-locking universal wheel 2 is provided at the lower end of the vehicle body 1. A telescopic plate 3 is slidably connected to the vehicle body 1. An installation groove 5 is formed on the telescopic plate 3. A winch 6 is rotatably connected inside the installation groove 5. A servo motor 4 is fixedly connected to one side of the telescopic plate 3. The output end of the servo motor 4 is fixedly connected to the winch 6. A lifting rope 7 is wound around the winch 6. One end of the lifting rope 7 away from the winch 6 is fixedly connected to a counterweight 9. A water sampling ball 8 is slidably connected to the lifting rope 7. An adjusting mechanism is provided on the water sampling ball 8;

[0021] The lifting rope 7 is a nylon rope or a hemp rope formed by multi-strand winding.

[0022] By slidably connecting the telescopic plate 3 to the vehicle body 1, the telescopic plate 3 can slide, so that the winch 6 and the lifting rope 7 can be perpendicular above the water surface, which is convenient for collecting water quality at different positions;

[0023] At the same time, through the provided self-locking universal wheel 2, the vehicle body 1 is more convenient and faster to move during the movement process, reducing the labor intensity of the operator during the pushing process. And when the servo motor 4 is started, the lifting rope 7 can be gradually loosened and wound on the winch 6, so that the water sampling ball 8 enters the water body and is pulled out from the water body, thus completing the collection of the water body.

[0024] The setting of the counterweight 9 ensures that the water sampling ball 8 can enter the water at different depths, thus completing the collection of the water bodies in different water layers, avoiding the floating phenomenon of the water sampling ball 8, and ensuring the normal collection of the water body.

[0025] Furthermore, a telescopic rod 10 is fixedly connected inside the vehicle body 1. The output end of the telescopic rod 10 is fixedly connected to the telescopic plate 3;

[0026] The telescopic rod 10 includes but is not limited to general components with telescopic functions such as a hydraulic telescopic rod and an electric telescopic rod, or a telescopic component with the same function well known to those skilled in the art.

[0027] When the telescopic plate 3 needs to be extended or retracted, the extension and retraction of the telescopic plate 3 can be completed by simply starting the telescopic rod 10 .

[0028] Further, the adjustment mechanism includes a U-shaped connection block 13, the connection block 13 is fixedly connected to the water collection ball 8, the suspension rope 7 passes through the connection block 13, and the connection block 13 is slidably connected to two insertion rods 15 on the side away from the water collection ball 8, and the insertion rod 15 is movably sleeved with a spring 16, and the two ends of the spring 16 are respectively fixedly connected to the surface of the insertion rod 15 and the connection block 13, and the two sides of the connection block 13 are respectively slidably connected with a fixed cone 14, and the inner wall of the connection block 13 is provided with two built-in holes 18, and the fixed cone 14 is respectively slidably connected to the inside of the built-in holes 18, and the fixed cone 14 is provided with a fixed hole 17, and the insertion rod 15 is movably connected to the inside of the fixed hole 17;

[0029] Among them, the end of the fixed cone 14 close to the insertion rod 15 is conical, and the end of the insertion rod 15 close to the fixed cone 14 is arc-shaped;

[0030] When it is necessary to collect water at different depths, the position of the water collecting ball 8 on the hanging rope 7 and the spacing between multiple water collecting balls 8 can be moved according to needs. At this time, when the water collecting ball 8 moves to the specified position, the fixed cone 14 is pushed. The fixed cone 14 penetrates the hanging rope 7 and is inserted into the interior of the built-in hole 18. Since one end of the insertion rod 15 is arc-shaped, the conical end of the fixed cone 14 applies pressure to the insertion rod 15, and the insertion rod 15 moves upward, so that the spring 16 is subjected to force. When the fixing hole 17 moves to the position of the insertion rod 15, the spring 16 drives the insertion rod 15 to reset, so that the insertion rod 15 is inserted into the interior of the fixing hole 17, thereby completing the fixation of the fixed cone 14. At this time, under the restriction of the fixed cone 14, the position of the water collecting ball 8 is fixed, thereby completing the adjustment of the water collecting ball 8, so that the device can collect water at different depths at the same time.

[0031] The interior of the water collecting ball 8 is a hollow structure and has a hollow tube, the hollow tube runs through the water collecting ball 8, and the hanging rope 7 is located inside the hollow tube;

[0032] By providing the hollow tube, the water collecting ball 8 is always in a sealed state, and it is ensured that it can slide normally on the suspension rope 7.

[0033] Furthermore, a water outlet pipe 12 is fixedly connected to the water collection ball 8 , an automatic control valve 11 is fixedly connected to the water collection ball 8 , and a sealing cover is provided on the water outlet pipe 12 .

[0034] Among them, the automatic control valve 11 is a pressure valve, that is, when the water collection ball 8 is inside the water body, the corresponding pressure can be set for the automatic control valve 11 according to the different depths of the water layer it collects. Therefore, when the water collection ball 8 enters the water level to the specified pressure, the automatic control valve 11 is automatically opened by the water pressure, thereby allowing the water to enter the interior of the water collection ball 8, thereby completing the collection of the water body.

[0035] Among them, a plurality of water collection balls 8 can be provided according to actual needs, and the specific number is not particularly limited here.

[0036] Working principle: When it is necessary to collect water at different depths, the position of the water collecting ball 8 on the hanging rope 7 and the spacing between multiple water collecting balls 8 can be moved according to needs. At this time, when the water collecting ball 8 moves to the specified position, it pushes the fixed cone 14, and the fixed cone 14 penetrates the hanging rope 7 and is inserted into the interior of the built-in hole 18. Since one end of the insertion rod 15 is arc-shaped, the conical end of the fixed cone 14 applies pressure to the insertion rod 15, and then the insertion rod 15 moves upward, so that the spring 16 is subjected to force. When the fixing hole 17 moves to the position of the insertion rod 15, the spring 16 drives the insertion rod 15 to reset, so that the insertion rod 15 is inserted into the interior of the fixing hole 17, thereby completing the fixation of the fixed cone 14. At this time, under the restriction of the fixed cone 14, the position of the water collecting ball 8 is fixed, thereby completing the adjustment of the water collecting ball 8, so that the device can collect water at different depths at the same time.

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
