Description

TECHNICAL FIELD

[0001] The utility model relates to water quality detection device technical field, specifically point to a water quality monitoring sampling equipment. BACKGROUND

[0002] Water quality detection is a key means to evaluate water resource quality. By detecting water quality, the content and properties of various substances in water can be understood, and whether water is suitable for different purposes such as drinking, irrigation, industrial production can be judged. Accurate water quality detection results are of great significance to human health, ecological environment and economic development.

[0003] In the process of water quality detection, sampling is a crucial step. Only by obtaining representative water samples can the accuracy and reliability of subsequent detection results be ensured. Sampling needs to be carried out at different water areas and different depths to fully understand the water quality. Under normal circumstances, multiple sampling detection needs to be carried out in the same area, and then the average value is taken to improve the precision of the detection results.

[0004] Traditional water quality monitoring sampling equipment often has the problem of only single-depth sampling. This results in the need for repeated sampling in each area during water quality detection, which not only consumes a lot of time and manpower, but also is inefficient. Since sampling cannot be carried out at different depths at the same time, it is difficult to fully and accurately reflect the overall water quality of the water area. In addition, multiple repeated sampling may introduce errors due to changes in environmental conditions, affecting the reliability of the detection results. UTILITY MODEL CONTENT

[0006] The purpose of the utility model patent is to provide a water quality monitoring sampling equipment to solve the problem of traditional water quality monitoring sampling equipment that can only sample at a single depth at a time.

[0007] (II) Technical content

[0008] To solve the above technical problems, the technical scheme of the utility model is as follows: a water quality monitoring sampling equipment, comprising a floating plate, a long strip-shaped through hole is arranged in the center of the floating plate, a multi-stage roller mechanism is fixedly arranged on the upper end face of the floating plate and above the long strip-shaped through hole, the multi-stage roller mechanism comprises two vertical plates fixedly arranged on the upper end face of the floating plate, a rotating shaft is rotatably arranged between the vertical plates, a motor for driving the rotating shaft to rotate is fixedly arranged on the outer side of the vertical plate, a plurality of rollers are fixedly arranged on the rotating shaft, the diameters of the plurality of rollers are different, a rope is wound around each roller, the lower end of the rope is fixedly provided with a sampling bottle, a water inlet is arranged at the bottom of the sampling bottle, a piston plate is slidably arranged in the sampling bottle, a pressure cavity is formed between the upper end of the piston plate and the inner top surface of the sampling bottle, and a gas pump is connected to the upper end of the pressure cavity.

[0009] Further, the air pump is fixed on the upper end surface of the floating plate, and the air outlet of the air pump is communicated with the pressure cavities of the sampling bottles through a plurality of hoses.

[0010] Further, a battery is fixed on the upper end surface of the floating plate to supply power to the motor and the air pump.

[0011] Further, a pull rope is fixed on each of the four corners of the upper end surface of the floating plate.

[0012] Further, the height of the sampling bottle is less than the depth of the long strip-shaped through hole, and the sampling bottle is accommodated in the long strip-shaped through hole in the initial state or the completed state.

[0013] Further, a rubber sealing ring is fixed on the side edge of the piston plate, and the rubber sealing ring is in contact with and slides along the inner wall of the sampling bottle.

[0014] Further, the water inlet is in the form of a circular hole and is arranged at the center of the bottom of the sampling bottle, and a plug is inserted into the water inlet.

[0015] (Three) technical effects

[0016] Compared with the prior art, the utility model has the advantages that a multi-stage winding roller mechanism is arranged, the mechanism is composed of two vertical plates, a rotating shaft, a motor and a plurality of winding rollers with different diameters. A rope is wound around each winding roller, and the lower end of the rope is connected to a sampling bottle. When multi-depth sampling is needed, the motor drives the rotating shaft to rotate. Since the linear speed of the winding rollers with different diameters is the same, and the circumferences are different, the lengths of the ropes wound around the winding rollers are different. The rope wound around the winding roller with a larger diameter is longer, and the sampling bottle connected to the lower end of the rope is immersed in deeper water. The rope wound around the winding roller with a smaller diameter is shorter, and the corresponding sampling bottle is immersed in shallower water. In this way, a plurality of sampling bottles can reach different depths at the same time. When the sampling bottles reach the predetermined depth, the air pump works, the pressure in the pressure cavity of the sampling bottle is changed, the piston plate moves upward, and water at different depths is collected in the sampling bottles at the same time. Thus, the problem that the conventional sampling equipment can only sample at a single depth at a time is solved, and more comprehensive and accurate data for water quality monitoring are provided.

[0026] The present application will be further described in detail below in combination with the drawings.

[0028] In the embodiment, as a preferred technical solution, the air pump 12 is fixedly arranged on the upper end surface of the float plate 1, and the air outlet of the air pump 12 is communicated with the pressure cavity 11 of each sampling bottle 8 through multiple hoses 13. The upper end surface of the float plate 1 is fixedly arranged with a storage battery 14, and the storage battery 14 supplies power to the motor 5 and the air pump 12. The upper end surface of the float plate 1 is fixedly arranged with a pull rope 15 at each corner.

[0029] In the embodiment, as a preferred technical solution, the height of the sampling bottle 8 is less than the depth of the long strip shape through -hole 2, and the sampling bottle 8 is accommodated into the long strip shape through -hole 2 in the initial state or the completed state of sampling. The side edge of the piston plate 10 is fixedly arranged with a rubber sealing ring 16, which is in contact with and slides along the inner wall of the sampling bottle 8. The water inlet 9 is in the form of a circular hole and is arranged at the center of the bottom of the sampling bottle 8, and a plug is inserted into the water inlet 9.

[0030] The working principle of the water quality monitoring sampling equipment is as follows: the equipment mainly uses the multiple stage roll mechanism and the piston type sampling bottle. The motor 5 drives the rotation of the rotation shaft 4, controls the roll 6 with different diameters to lower the rope 7, and makes the sampling bottle 8 connected to the lower end of the rope 7 reach different depths. Then, the air pump 12 changes the pressure of the pressure cavity 11 in the sampling bottle 8, controls the movement of the piston plate 10, and realizes the collection of water samples at different depths.

[0031] The use process of the water quality monitoring sampling equipment is as follows:

[0032] 1. Preparation: Place the equipment above the water area where water quality monitoring is needed to ensure that the float plate 1 floats stably. Check whether each component is working normally, such as the motor 5, the air pump 12, the storage battery 14, etc. Confirm that the water inlet 9 at the bottom of the sampling bottle 8 is in an open state. The air pump 12 inflates the pressure cavity 11 in the sampling bottle 8 through the hose 13, increases the pressure of the pressure cavity 11, and makes the inside of the pressure cavity in a positive pressure state. Under the action of air pressure, the piston plate 10 moves to the bottom of the sampling bottle 8 and blocks the water inlet 9. The air pump 12 keeps the positive pressure state of the pressure cavity.

[0033] 2. Lowering the sampling bottles: start the motor 5, the motor 5 drives the rotating shaft 4 to rotate, and the winding rollers 6 of different diameters start to lower the ropes 7. Because the winding rollers 6 are of different diameters, the lengths of the ropes 7 are also different, so that the sampling bottles 8 connected to the lower ends of the ropes 7 reach different depths. In this process, the lowering of the sampling bottles 8 is observed to ensure that they reach the predetermined depths smoothly. It should be noted that the weight and material of the sampling bottles 8 are sufficient to make them sink.

[0034] 3. Collecting water samples: when the multiple sampling bottles 8 all reach the predetermined different depths, the air pump 12 is started in reverse, the air in the pressure cavity is discharged, at this time, the pressure cavity is in a negative pressure state, the piston plate 10 slowly moves upwards, and water starts to enter the sampling bottles 8 from the water inlets 9 until the sampling bottles 8 are filled with water samples.

[0035] 4. Lifting the sampling bottles: after collecting the water samples, the motor 5 is started again to rotate in reverse, driving the rotating shaft 4 and the winding rollers 6 to recover the ropes 7. Because the sampling bottles are contained in the long strip-shaped through holes 2 and are at the same horizontal height when lowering the ropes, the sampling bottles 8 are recovered at the same time, and the multiple sampling bottles 8 are recovered into the long strip-shaped through holes 2. Because of the sealing effect of the piston plate 10, even if the water inlets 9 are opened, they will not leak out. The principle is the same as that of a syringe. After the water surface is taken out, the water inlets are sealed with plugs.

[0036] 5. Taking out the water samples for detection: when detection is needed, the water inlets 9 at the bottoms of the sampling bottles 8 are opened, and the water samples are taken out for detection. Different depths of water samples can be detected separately, or multiple water samples can be mixed and detected to obtain more comprehensive water quality information.

[0037] The above describes the present application and its embodiments, which are not limited. The embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by this, without departing from the creative purpose of the present application, without creative design, similar structural modes and embodiments of the technical solutions can be obtained, which should belong to the protection scope of the present application.
