Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring and sampling technology, and specifically relates to a groundwater sampling device for environmental monitoring. Background Technology

[0002] Ecological and environmental monitoring is the process of intermittently or continuously observing, measuring, and analyzing the changes and environmental impacts of one or more environmental elements or indicators, according to a pre-designed time and space and using comparable environmental information and data collection methods, for a specific purpose. Environmental monitoring is the foundation of environmental protection work and the basis for environmental legislation, environmental planning, and environmental decision-making. Environmental monitoring is one of the important means of environmental management.

[0003] The purpose of water quality monitoring is to examine environmental quality, study whether the water quality is suitable or usable, examine the pollution or degree of pollution of water, and check the efficiency of water treatment processes.

[0004] Currently, groundwater sampling equipment mainly uses one-time fixed-depth sampling. Sampling at different depths requires repeated sampling operations. If the liquid in the previous sampling container is not cleaned properly, it will interfere with the sample taken in the next sampling to some extent.

[0005] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, they have been modified and improved. In the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created to provide a groundwater sampling device for environmental monitoring to solve the above-mentioned problems. Utility Model Content

[0006] This invention proposes a groundwater sampling device for environmental monitoring, which solves the problems in the prior art.

[0007] The technical solution of this utility model is implemented as follows: a groundwater sampling device for environmental monitoring includes: a controller body, an outer shell is provided at the bottom of the controller body, a rope winding mechanism is provided inside the outer shell, a cable is wound on the rope winding mechanism, and a sampling box is provided at the end of the cable.

[0008] In a preferred embodiment of a groundwater sampling device for environmental monitoring, a first side ear is provided on the outer wall of the controller body, and a fastening bolt is provided on the first side ear. A second side ear is provided on the outer wall of the outer casing, and the first side ear is fixedly engaged with the second side ear by the fastening bolt.

[0009] In a preferred embodiment of a groundwater sampling device for environmental monitoring, the top of the outer casing is provided with a slot, and a sealing ring is fitted inside the slot.

[0010] Using the above solution, the sealing ring achieves a tight seal between the outer casing and the controller body, preventing the intrusion of dust, moisture, and other contaminants.

[0011] In a preferred embodiment of a groundwater sampling device for environmental monitoring, a chamber is provided inside the outer casing, and a rope winding mechanism is fitted inside the chamber. The rope winding mechanism includes two support frames, and a winding frame body is fitted between the two support frames. A rope winding roller is provided in the middle of the winding frame body. The rope winding roller extends through the support frames to both ends, and a drive motor is fitted at one end of the rope winding roller. The cable is wound around the rope winding roller.

[0012] Using the above scheme, the drive motor serves as the power source, and through transmission, it enables the rotation of the take-up and take-down frame, thereby realizing the take-up and take-down of the cable and achieving subsequent sampling.

[0013] In a preferred embodiment of a groundwater sampling device for environmental monitoring, a float is slidably fitted on the cable, and the float is positioned between the outer casing and the sampling box.

[0014] In a preferred embodiment of a groundwater sampling device for environmental monitoring, an iron ring is provided inside the float.

[0015] In a preferred embodiment of a groundwater sampling device for environmental monitoring, the sampling box is provided with multiple independent liquid storage chambers, each of which is equipped with a solenoid valve, which is fixed to the bottom of the sampling box.

[0016] Using the above scheme, multiple independent storage chambers can store samples. When the solenoid valve is turned on, groundwater will enter the independent storage chamber, thereby achieving the purpose of sampling. Similarly, the groundwater can be discharged by turning on the solenoid valve.

[0017] In a preferred embodiment of a groundwater sampling device for environmental monitoring, one end of the cable is electrically connected to the controller body, and the other end is electrically connected to the solenoid valve.

[0018] In a preferred embodiment of a groundwater sampling device for environmental monitoring, the cable is equipped with multiple inductive proximity sensors, with each inductive proximity sensor spaced 5m apart from the next adjacent inductive proximity sensor.

[0019] Using the above scheme, the inductive proximity sensor can be combined with the iron ring inside the float to achieve fixed-depth sampling, in which the float rises due to buoyancy during the descent of the cable.

[0020] An inductive proximity sensor consists of four main parts: a ferrite core with a coil, an oscillator, a Schmitt trigger, and an output amplifier. The oscillator generates a symmetrical oscillating magnetic field. When the iron ring enters the oscillating magnetic field, the inductive properties of the metal change the characteristics of the magnetic field, thus alerting the inductive proximity sensor to the presence of metal. At this time, the electrical signal output by the inductive proximity sensor will determine that the sampling box is at a certain accurate position. The float can achieve constant depth adjustment according to different inductive proximity sensors.

[0021] After adopting the above technical solution, the beneficial effects of this utility model are: this equipment can realize groundwater sampling, especially multiple fixed-depth sampling, so as to achieve better sampling results.

[0022] The drive motor rotates the launching frame via transmission, thus lowering the cable. When the float comes into contact with groundwater, it rises due to buoyancy. When the iron ring in the float enters the oscillating magnetic field generated by the inductive proximity sensor, it changes the characteristics of the magnetic field, thus alerting the inductive proximity sensor to the presence of metal. At this time, the electrical signal output by the inductive proximity sensor determines that the sampling box is in a precise position. Then, the control solenoid valve is turned on, and groundwater enters the independent storage chamber, thereby achieving the purpose of sampling.

[0023] Multiple inductive proximity sensors are installed inside the cable, and depth adjustment can be achieved when the float corresponds to different inductive proximity sensors. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] like Figure 1-3 As shown, a groundwater sampling device for environmental monitoring includes: a controller body 1, an outer shell 2 is provided at the bottom of the controller body 1, a rope winding mechanism 4 is provided inside the outer shell 2, a cable 45 is wound on the rope winding mechanism 4, and a sampling box 6 is provided at the end of the cable 45.

[0034] The controller body 1 has a first side ear 11 on its outer wall and a fastening bolt on the first side ear 11. The outer wall of the outer casing 2 has a second side ear 21. The first side ear 11 is fixedly engaged with the second side ear 21 by the fastening bolt.

[0035] The outer casing 2 has a slot 22 on its top, and a sealing ring 3 is fitted inside the slot 22.

[0036] Furthermore, the sealing ring 3 achieves a seal between the outer casing 2 and the controller body 1, preventing the intrusion of dust, moisture, etc.

[0037] like Figure 4 As shown, a chamber 23 is provided inside the outer casing 2. The rope winding and unwinding mechanism 4 is fitted inside the chamber 23. The rope winding and unwinding mechanism 4 includes two support frames 41. A winding and unwinding frame body 42 is fitted between the two support frames 41. A rope winding roller 43 is provided in the middle of the winding and unwinding frame body 42. The rope winding roller 43 extends through the support frame 41 to both ends. A drive motor 44 is fitted at one end of the rope winding roller 43. The cable 45 is wound on the rope winding roller 43.

[0038] like Figure 5-6As shown, a float 5 is slidably fitted on the cable 45, and the float 5 is located between the outer casing 2 and the sampling box 6.

[0039] Among them, the float 5 is equipped with an iron ring 51.

[0040] The sampling box 6 is equipped with multiple independent liquid storage chambers 61, and each independent liquid storage chamber 61 is equipped with a solenoid valve 62, which is fixed to the bottom of the sampling box 6.

[0041] One end of the cable 45 is electrically connected to the controller body 1, and the other end is electrically connected to the solenoid valve 62.

[0042] The cable 45 contains multiple inductive proximity sensors 451, with each inductive proximity sensor 451 spaced 5m apart from the next adjacent inductive proximity sensor 451.

[0043] Furthermore, multiple independent storage chambers 61 can all store samples. When the solenoid valve 62 is turned on, groundwater will enter the independent storage chamber 61 to achieve the purpose of sampling. Similarly, the groundwater sample can also be exported by turning on the solenoid valve 62.

[0044] Furthermore, the inductive proximity sensor 451 can cooperate with the iron ring 51 inside the float 5 to achieve fixed-depth sampling, wherein the float 5 rises due to buoyancy during the descent of the cable 45.

[0045] The inductive proximity sensor 451 consists of four main parts: a ferrite core with a coil, an oscillator, a Schmitt trigger, and an output amplifier. The oscillator generates a symmetrical oscillating magnetic field. When the iron ring 51 enters the oscillating magnetic field, the inductive characteristics of the metal will change the characteristics of the magnetic field, thereby alerting the inductive proximity sensor 451 to the presence of metal. At this time, the electrical signal output by the inductive proximity sensor 451 will determine that the sampling box 6 is in a certain accurate position. The float 5 can achieve constant depth adjustment by corresponding to different inductive proximity sensors 451.

[0046] The working principle is as follows: the drive motor 44 drives the rotation of the launch frame 42 through transmission, thereby lowering the cable 45. When the float 5 comes into contact with the groundwater, it will rise due to buoyancy. When the iron ring in the float 5 enters the oscillating magnetic field generated by the inductive proximity sensor 451, it will change the characteristics of the magnetic field, thereby alerting the inductive proximity sensor 451 to the presence of metal. At this time, the electrical signal output by the inductive proximity sensor 451 will determine that the sampling box 6 is in a certain accurate position. Then, the control solenoid valve 62 is turned on, and the groundwater will enter the independent storage chamber, thereby achieving the purpose of sampling.
