Description

Technical Field

[0001] This utility model relates to the field of water quality sampler technology, specifically a water quality sampler capable of quantitative sampling. Background Technology

[0002] Currently, staff often need to use water samplers when conducting water quality sampling to facilitate sampling and improve work efficiency. Although existing water samplers can automatically and quantitatively sample water sources, making sampling easier, in actual use, staff often need to sample water sources at different depths. When adjusting the depth of the sampling bottle, the opening of the sampling bottle lacks a sufficiently effective sealing structure, making it easy for water to enter the bottle at the opening, allowing water from depths other than the sampling depth to enter the sampling bottle prematurely. Utility Model Content

[0003] The purpose of this invention is to provide a water quality sampler capable of quantitative sampling, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water quality sampler capable of quantitative sampling, comprising a sampling cylinder, a detachable top cover threadedly connected to the top of the sampling cylinder, a quantitative component provided at the bottom of the sampling cylinder, a depth adjustment rope fixedly connected to the top of the detachable top cover, two depth adjustment ropes provided and symmetrically arranged relative to the detachable top cover, a sealing shell movably provided on the inner wall of the detachable top cover, an electromagnet provided inside the sealing shell, a sliding guide component provided inside the detachable top cover, the sliding guide component guiding the sealing shell, the top of the sealing shell extending into an opening at the top of the detachable top cover, and a sealing ring fixedly installed in the opening, a conductive wire harness connected to the electromagnet, the conductive wire harness extending from the top of the sealing shell, and a ferritic stainless steel ring fixedly installed on the inner wall of the top of the sealing shell.

[0005] Furthermore, a sealing cover is fixedly installed on the top of the detachable top cover. The sealing cover covers the part of the sealing shell through which the conductive wire harness passes. The top of the sealing cover is connected to a sealing wire harness tube, which is sleeved on the conductive wire harness.

[0006] Furthermore, the sliding guide assembly includes a fixing frame and a guide groove. The fixing frame is fixedly installed on the inner wall of the detachable top cover, the guide groove is opened at the bottom of the sealed outer shell, and a guide rod is fixedly installed on the top of the fixing frame. The guide rod is slidably disposed in the guide groove.

[0007] Furthermore, the quantitative component includes a piston, a counterweight, and a mounting base. The piston is slidably disposed inside the sampling cylinder. A threaded rod is rotatably connected to the bottom of the piston via a bearing. The mounting base is fixedly installed at the bottom end of the sampling cylinder and threadedly sleeved on the outer wall of the threaded rod. The counterweight is slidably sleeved on the outer wall of the threaded rod. A rotating connector is fixedly installed at the bottom of the mounting base. The rotating end of the rotating connector is fixedly connected to the top of the counterweight. An integrally formed protrusion is provided on the inner wall of the counterweight. A groove is formed on the outer wall of the threaded rod, and the protrusion is slidably disposed within the groove.

[0008] Furthermore, the rotating connector includes an inner collar and an outer collar, the outer collar being slidably sleeved outside the inner collar, the top of the inner collar being fixedly connected to the bottom of the mounting base, and the bottom of the outer collar being fixedly connected to the top of the counterweight.

[0009] Furthermore, a handle is fixedly fitted on the outer wall of the counterweight, and ventilation channels are provided on the mounting base and the rotating connector.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The water depth of the sampling tube is adjusted by pulling the depth adjustment rope. During the adjustment process, the electromagnet is energized through the conductive wire bundle, making the electromagnet magnetic. The magnetic attraction between the electromagnet and the ferrite stainless steel ring will cause the electromagnet to move upward, which in turn will drive the sealing shell upward, so that the top of the sealing shell is engaged with the inner side of the sealing ring, sealing the top opening of the detachable top cover. This can effectively prevent the top opening of the detachable top cover from not sealing tightly when adjusting the depth of the sampling tube, and thus prevent water from entering the sampling tube at a depth other than the sampling depth in advance.

[0012] 2. The counterweight is designed with protrusions and grooves so that the rotating counterweight can drive the threaded rod to rotate synchronously. The threaded rod can also move up and down relative to the counterweight. When it is necessary to adjust the position of the piston in the sampling cylinder, simply rotate the counterweight to drive the threaded rod to rotate. During the rotation of the threaded rod, it moves up and down under the action of the internal thread of the mounting base, thereby driving the piston to move up and down. This is used to adjust the sampling depth in the sampling cylinder and thus control the amount of sample taken. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-5This utility model provides a technical solution: a water quality sampler capable of quantitative sampling, including a sampling cylinder 1, a detachable top cover 2 threadedly connected to the top of the sampling cylinder 1, a quantitative component 3 provided at the bottom of the sampling cylinder 1, a depth adjustment rope 4 fixedly connected to the top of the detachable top cover 2, two depth adjustment ropes 4 provided and symmetrically arranged with respect to the detachable top cover 2, a sealing shell 5 movably provided on the inner wall of the detachable top cover 2, an electromagnet 6 provided inside the sealing shell 5, a sliding guide component 8 provided inside the detachable top cover 2, the sliding guide component 8 guiding the sealing shell 5, the top of the sealing shell 5 extending into the opening at the top of the detachable top cover 2, and a sealing ring 9 fixedly installed in the opening, a conductive wire harness 7 connected to the electromagnet 6, the conductive wire harness... 7 extends from the top of the sealed outer shell 5. A ferritic stainless steel ring 10 is fixedly installed on the inner wall of the top of the sealed outer shell 5. The water immersion depth of the sampling cylinder 1 is adjusted by pulling the depth adjustment rope 4. During the adjustment process, the electromagnet 6 is energized through the conductive wire harness 7, so that the electromagnet 6 becomes magnetic. Then, the magnetic attraction between the electromagnet 6 and the ferritic stainless steel ring 10 will cause the electromagnet 6 to move upward, thereby driving the sealed outer shell 5 to move upward, so that the top of the sealed outer shell 5 is inserted into the inner side of the sealing ring 9, sealing the top opening of the detachable top cover 2. This can effectively prevent the top opening of the detachable top cover 2 from not sealing tightly when adjusting the depth of the sampling cylinder 1, thereby preventing water from entering the sampling cylinder 1 at a depth other than the sampling depth in advance. A quantitative component 3 is set to adjust the amount of water that can be sampled in the sampling cylinder 1.

[0021] A sealing cover 11 is fixedly installed on the top of the detachable top cover 2. The sealing cover 11 covers the part of the sealing shell 5 through which the conductive wire harness 7 passes. The top of the sealing cover 11 is connected to a sealing wire harness tube 12. The sealing wire harness tube 12 is sleeved on the conductive wire harness 7. The sealing cover 11 and the sealing wire harness tube 12 are used to protect the conductive wire harness 7 and prevent the conductive wire harness 7 from being corroded by water and to prevent water from entering the sealing shell 5 from the part of the sealing shell 5 through which the conductive wire harness 7 passes.

[0022] The sliding guide assembly 8 includes a fixing frame 801 and a guide groove 803. The fixing frame 801 is fixedly installed on the inner wall of the detachable top cover 2. The guide groove 803 is opened at the bottom of the sealing shell 5. A guide rod 802 is fixedly installed on the top of the fixing frame 801. The guide rod 802 is slidably disposed in the guide groove 803. The fixing frame 801 is used to install the guide rod 802. The guide rod 802 inserted into the guide groove 803 guides the sealing shell 5, so that the sealing shell 5 can rotate and slide up and down, but there should be no radial movement, ensuring that the sealing shell 5 can move up and down and be inserted into the top opening of the detachable top cover 2.

[0023] The quantitative component 3 includes a piston 301, a counterweight 303, and a mounting base 304. The piston 301 is slidably disposed inside the sampling cylinder 1. A threaded rod 302 is rotatably connected to the bottom of the piston 301 via a bearing. The mounting base 304 is fixedly installed at the bottom end of the sampling cylinder 1 and is threaded onto the outer wall of the threaded rod 302. The counterweight 303 is slidably disposed on the outer wall of the threaded rod 302. A rotary connector 305 is fixedly installed at the bottom of the mounting base 304. The rotating end of the rotary connector 305 is fixedly connected to the top of the counterweight 303. An integrally formed protrusion 306 is provided on the inner wall of the counterweight 303. The outer wall of 302 has a groove 307, and a protrusion 306 is slidably disposed in the groove 307. The protrusion 306 and the groove 307 are provided so that when the counterweight 303 rotates, it can drive the threaded rod 302 to rotate synchronously. The threaded rod 302 can also move up and down relative to the counterweight 303. When it is necessary to adjust the position of the piston 301 in the sampling cylinder 1, simply rotate the counterweight 303 to drive the threaded rod 302 to rotate. During the rotation of the threaded rod 302, it moves up and down under the action of the thread in the mounting base 304, thereby driving the piston 301 to move up and down, which is used to adjust the sampling depth in the sampling cylinder 1, thereby controlling the amount of sampling.

[0024] The rotating connector 305 includes an inner collar 3051 and an outer collar 3052. The outer collar 3052 is slidably sleeved on the outside of the inner collar 3051. The top of the inner collar 3051 is fixedly connected to the bottom of the mounting base 304, and the bottom of the outer collar 3052 is fixedly connected to the top of the counterweight 303. The counterweight 303 and the mounting base 304 are connected by the relatively rotatable inner collar 3051 and outer collar 3052, ensuring that the mounting base 304 will not be rotated when the counterweight 303 is rotated, and the counterweight 303 will not fall off the mounting base 304.

[0025] A handle 13 is fixedly fitted on the outer wall of the counterweight 303. A ventilation channel 14 is provided on the mounting base 304 and the rotating connector 305. The handle 13 makes it easier to rotate the counterweight 303. The ventilation channel 14 allows the air in the space below the piston 301 to flow freely when the piston 301 slides up and down in the sampling cylinder 1.

[0026] Working principle: In use, depending on the required sampling amount, rotating the handle 13 rotates the counterweight 303, which in turn rotates the threaded rod 302, causing the threaded rod 302 to move up or down, which in turn moves the piston 301 up or down, thus adjusting the water volume that the sampling cylinder 1 can hold. Before vertically immersing the sampling cylinder 1 in the water, the power is turned on to supply power to the electromagnet 6, causing the electromagnet 6 to generate magnetic force. Under the magnetic attraction of the ferrite stainless steel ring 10, the electromagnet 6 moves upward, causing the sealing shell 5 to move upward, so that the top of the sealing shell 5 is engaged with the inner side of the sealing ring 9, sealing the top opening of the detachable top cover 2. Then, the sampling cylinder 1 is vertically immersed in the water, and the position of the sampling cylinder 1 in the water is adjusted by pulling the two depth adjustment ropes 4. After reaching the sampling depth, the power is turned off, causing the electromagnet 6 to lose its magnetism. At this time, under the action of water pressure and the gravity of the sealing shell 5 and the electromagnet 6 itself, the sealing shell 5 moves downward relative to the detachable top cover 2, exposing the top opening of the detachable top cover 2. Water enters the sampling cylinder 1 and the detachable top cover 2 from the top opening of the detachable top cover 2. After a period of time (when the sampling cylinder 1 and the detachable top cover 2 are full of water), the power is turned on to supply power to the electromagnet 6. As described above, the electromagnet 6 drives the sealing shell 5 to move upward. The sealing shell 5 is inserted into the inner side of the sealing ring 9, sealing the top opening of the detachable top cover 2. Pulling up the depth adjustment rope 4 will pull the entire sampler out of the water. During this process, the sealing shell 5 keeps the top opening of the detachable top cover 2 sealed.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
