Description
Technical Field
[0001] This utility model relates to the field of water quality sampling technology, and in particular to a water quality sampler for environmental pollution sources. Background Technology
[0002] Environmental pollution source water quality samplers are specialized instruments used to collect water samples from environmental pollution sources. Depending on the application scenario and needs, some samplers can use vacuum suction or piston extraction. These two methods have their own characteristics. Vacuum suction can quickly obtain water samples, but it will have a certain impact on the physical properties of the water samples. Piston extraction can control the sampling volume more precisely, but the operation is relatively complicated.
[0003] A search revealed Chinese Patent Publication No. CN220690570U, which discloses a water quality sampler for environmental pollution sources, comprising a connecting cylinder, a sampling tube, and a driving component. The connecting cylinder has a mounting hole matching the sampling tube, and the sampling tube is detachably installed within the mounting hole. The sampling tube includes an interconnected suction section and a telescopic section. The telescopic section, when compressed, creates a negative pressure, and the suction section collects water samples from the pollution source. The driving component is installed at the end of the connecting cylinder furthest from the sampling tube. The driving component creates a negative pressure environment by compressing the telescopic section. This utility model... By compressing and releasing the telescopic part of the sampling tube through the driving component, the rebound of the sampling tube can be used to quickly draw up water samples from the pollution source, thereby achieving rapid collection of water samples from the pollution source. In addition, the sampling tube can be quickly disassembled, making it convenient to collect water samples from the pollution source. It has the characteristics of simple structure and convenient operation. However, existing environmental pollution source water quality samplers are divided into two types: shallow water sampling and deep water sampling. Since the sampling depth of these two types of sampling devices is fixed, this results in poor versatility of environmental pollution source water quality samplers. When the sampling environment is complex, it is necessary to carry multiple environmental pollution source water quality samplers. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a water quality sampler for environmental pollution sources, aiming to improve the problem that the sampling depth of existing water quality samplers for environmental pollution sources is fixed, resulting in poor versatility, and that multiple samplers are required when the sampling environment is complex.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water quality sampler for environmental pollution sources, comprising a fixed plate, a rocker arm rotatably connected to the lower right side of the fixed plate, a bevel gear one fixedly connected to the left side of the rocker arm, a slide bar fixedly connected to the bottom of the fixed plate, a threaded rod rotatably connected to the middle of the slide bar, a bevel gear two fixedly connected to the top of the threaded rod, the bevel gear two meshing with the bevel gear one, a lifting block threadedly connected to the outer wall of the threaded rod, limit rods slidably connected to the left and right sides of the lifting block, and a water quality sampling mechanism fixedly connected to the front side of the lifting block, the water quality sampling mechanism being used to extract water quality samples.
[0006] The above technical solution involves placing the environmental pollution source water sampler into the water when sampling a certain water area. Then, the rocker arm is turned to drive the rotation of bevel gear one. When bevel gear one rotates, it will drive bevel gear two to rotate synchronously through meshing. When bevel gear two rotates, the threaded rod fixed under it will also rotate together. When the threaded rod rotates, it will control the lifting block to slide up and down in the slide bar through the thread. When the lifting block slides up and down, two limit rods will restrict it to prevent the lifting block from rotating on its own.
[0007] As a further description of the above technical solution:
[0008] The water quality sampling mechanism includes a rotating handle. The outer wall of the rotating handle is rotatably connected to the upper left side of the fixed plate. A take-up reel is fixedly connected to the outer right side of the rotating handle. A lifting rope is fixedly connected to the outside of the take-up reel. A piston rod is fixedly connected to the end of the lifting rope. A sampling tube is slidably connected to the outer wall of the piston rod. Multiple thin plastic sheets are fixedly connected at equal intervals to the bottom inner side of the sampling tube.
[0009] The above technical solution works as follows: when the environmental pollution source water quality sampler reaches the designated sampling position, the handle is rotated. When the handle rotates, it will drive the take-up reel fixed on it to start rotating. When the take-up reel rotates, the lifting rope fixed on it will start to be retracted. As the lifting rope is retracted, the piston rod fixed on its other end will be pulled upward. As the piston rod rises, a negative pressure will be formed in the sampling tube. At this time, as a negative pressure is formed in the sampling tube, multiple thin plastic sheets fixed at the bottom of the sampling tube will be sucked inward and bent. At the same time, water outside the environmental pollution source water quality sampler will also be sucked into the sampling tube.
[0010] As a further description of the above technical solution:
[0011] A rubber sleeve is fixedly connected to the outer wall of the rocker arm, and the outer wall of the rubber sleeve is provided with anti-slip texture.
[0012] Through the above technical solution, the rubber sleeve improves the grip stability of the joystick through its anti-slip texture.
[0013] As a further description of the above technical solution:
[0014] Hooks are installed on the left and right ends of the top rear side of the slide bar, and two screws are threadedly connected at equal intervals to the lower middle part of the two hooks.
[0015] The above technical solution allows the sampler to be easily hung outside the ship for sampling by fixing a hook behind the slider with a screw.
[0016] As a further description of the above technical solution:
[0017] The upper rear side of the slider is threaded with multiple screws at equal intervals, and each screw has a protective pad threaded to its exterior.
[0018] The above technical solution involves fixing the protective pad with screw two, which can prevent the ship and the water sampler from scratching each other.
[0019] As a further description of the above technical solution:
[0020] Multiple anti-slip sleeves are equidistantly installed on the outer wall of the handle, and Velcro is fixedly connected to the front and rear sides of the multiple anti-slip sleeves.
[0021] The above technical solution involves fixing the anti-slip sleeve to the outside of the handle using Velcro to enhance its anti-slip performance.
[0022] As a further description of the above technical solution:
[0023] A fixing ring is fixedly connected to the bottom of the sampling tube, and a filter screen is fixedly connected to the inner side of the fixing ring.
[0024] The above technical solution involves fixing the filter screen with a fixing ring below the sampling tube to filter foreign objects and impurities in the water and prevent clogging.
[0025] As a further description of the above technical solution:
[0026] Multiple protective rings are fixedly connected at equal intervals to the front side of the slide bar, and connecting rods are fixedly connected at equal intervals to the front ends of the multiple protective rings.
[0027] The above technical solution involves: a protective ring to protect the water sampler from impacts, and a connecting rod to ensure the stability between the protective rings.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, rotating the rocker arm drives the threaded rod to rotate through bevel gear one and bevel gear two, thereby controlling the up and down sliding of the lifting block in the slide bar. This achieves the effect of freely adjusting the sampling depth of the environmental pollution source water quality sampler, avoiding the problem of needing multiple environmental pollution source water quality samplers due to the complexity of the sampling water environment.
[0030] 2. In this utility model, rotating the handle drives the take-up reel to retract the lifting rope and pull the piston rod. At this time, a negative pressure is formed inside the sampling tube, which sucks multiple thin plastic sheets inward and bends them. At the same time, water outside the water quality sampler of the environmental pollution source is also sucked into the sampling tube, thereby achieving the effect of fixed-point sampling.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0039] Reference Figure 2 and Figure 3This utility model provides an embodiment of a water quality sampler for environmental pollution sources, comprising a fixed plate 1, a rocker arm 3 rotatably connected to the lower right side of the fixed plate 1, a bevel gear 4 fixedly connected to the left side of the rocker arm 3, the rocker arm 3 being fixed on the fixed plate 1 to drive the bevel gear 4 to rotate, a slide bar 7 fixedly connected to the bottom of the fixed plate 1, a threaded rod 6 rotatably connected to the middle of the slide bar 7, and a bevel gear 5 fixedly connected to the top of the threaded rod 6, the bevel gear 5 meshing with the bevel gear 4. 4. The threaded rod 6 is rotated by the bevel gear 2 5. The outer wall of the threaded rod 6 is threadedly connected to the lifting block 8. The threaded rod 6 drives the lifting block 8 to move up and down. The left and right sides of the lifting block 8 are slidably connected to the limit rod 9. The limit rod 9 prevents the lifting block 8 from rotating. The front side of the lifting block 8 is fixedly connected to the water quality sampling mechanism 2. The water quality sampling mechanism 2 is used to extract water quality samples. The outer wall of the rocker arm 3 is fixedly connected to the rubber sleeve 10. The outer wall of the rubber sleeve 10 is provided with anti-slip texture 11. The rubber sleeve 10 provides anti-slip properties for the rocker arm 3.
[0040] Specifically, when sampling a certain water area, the environmental pollution source water quality sampler is first placed in the water, and then the rocker arm 3 is turned to drive the rotation of the bevel gear 4. When the bevel gear 4 rotates, it will drive the bevel gear 5 to rotate synchronously through meshing. When the bevel gear 5 rotates, the threaded rod 6 fixed under it will also rotate together. When the threaded rod 6 rotates, it will control the lifting block 8 to slide up and down in the slide bar 7 through the thread. When the lifting block 8 slides up and down, the two limit rods 9 will restrict it to prevent the lifting block 8 from rotating on its own. This achieves the effect of freely adjusting the sampling depth of the environmental pollution source water quality sampler. The rubber sleeve 10 significantly improves the anti-slip performance of the rocker arm 3 through the anti-slip texture 11.
[0041] Reference Figure 4 and Figure 5 The water sampling mechanism 2 includes a handle 201. The outer wall of the handle 201 is rotatably connected to the upper left side of the fixed plate 1. A take-up reel 202 is fixedly connected to the outer right side of the handle 201. The handle 201 drives the take-up reel 202 to rotate. A lifting rope 203 is fixedly connected to the outside of the take-up reel 202. A piston rod 204 is fixedly connected to the end of the lifting rope 203. The take-up reel 202 pulls the piston rod 204 upward through the lifting rope 203. A sampling tube 20 is slidably connected to the outer wall of the piston rod 204. 5. Multiple thin plastic sheets 206 are fixedly connected at equal intervals to the bottom inner side of the sampling tube 205. The thin plastic sheets 206 can prevent water from entering the sampling tube 205 in advance. Multiple anti-slip sleeves 16 are installed at equal intervals on the outer wall of the handle 201. Velcro 17 is fixedly connected to the front and rear sides of the multiple anti-slip sleeves 16. The anti-slip sleeves 16 improve the anti-slip performance of the handle 201. A fixing ring 18 is fixedly connected to the bottom of the sampling tube 205. A filter screen 19 is fixedly connected to the inner side of the fixing ring 18. Foreign objects in the water are filtered through the filter screen 19.
[0042] Specifically, when the environmental pollution source water quality sampler reaches the designated sampling position, the handle 201 is rotated. When the handle 201 rotates, it drives the take-up reel 202 fixed on it to start rotating. When the take-up reel 202 rotates, the lifting rope 203 fixed on it will start to be retracted. As the lifting rope 203 is retracted, the piston rod 204 fixed on its other end will be pulled upward. As the piston rod 204 rises, a negative pressure will be formed in the sampling tube 205. At this time, as a negative pressure is formed in the sampling tube 205, multiple thin plastic sheets 206 fixed at the bottom of the sampling tube 205 will be sucked inward and bent. At the same time, water outside the environmental pollution source water quality sampler will also be sucked into the sampling tube 205, thus achieving the effect of fixed-point sampling. The anti-slip sleeve 16 fixed to the outside of the handle 201 by Velcro 17 can provide an anti-slip effect. The filter screen 19 fixed to the bottom of the sampling tube 205 by the fixing ring 18 can filter foreign objects and impurities in the water and prevent the sampling tube 205 from being blocked.
[0043] Reference Figure 1 and Figure 3 Hooks 12 are installed on the top left and right sides of the rear side of the slide bar 7. Two screws 13 are threaded at equal intervals on the lower middle part of the two hooks 12. The environmental pollution source water quality sampler can be fixed to the outside of the boat through the hooks 12. Multiple screws 15 are threaded at equal intervals on the upper middle part of the rear side of the slide bar 7. Protective pads 14 are threaded on the outside of the multiple screws 15. The protective pads 14 can prevent the environmental pollution source water quality sampler from scratching the hull. Multiple protective rings 20 are fixedly connected at equal intervals on the front side of the slide bar 7. Connecting rods 21 are fixedly connected at equal intervals on the front end of the multiple protective rings 20. The protective rings 20 and connecting rods 21 can protect the environmental pollution source water quality sampler from being damaged.
[0044] Specifically, the hook 12, which is fixed to the slide bar 7 by screw 13, facilitates the hanging of the environmental pollution source water quality sampler outside the ship for sampling. The protective pad 14, which is fixed by screw 2 15, can provide protection between the ship and the environmental pollution source water quality sampler to prevent scratches. The protective ring 20 provides protection for the environmental pollution source water quality sampler, while the connecting rod 21 provides stability between the multiple protective rings 20.
[0045] Working principle: When sampling a certain water area, the environmental pollution source water quality sampler is first placed in the water. Then, the rocker arm 3 is turned to drive the rotation of bevel gear 4. When bevel gear 4 rotates, it will drive bevel gear 5 to rotate synchronously through meshing. When bevel gear 5 rotates, the threaded rod 6 fixed below it will also rotate together. When the threaded rod 6 rotates, it will control the lifting block 8 to slide up and down in the slide bar 7 through the thread. When the lifting block 8 slides up and down, the two limit rods 9 will restrict it to prevent the lifting block 8 from rotating on its own. In this way, the sampling depth of the environmental pollution source water quality sampler can be freely adjusted, avoiding the problem of needing multiple environmental pollution source water quality samplers due to the complexity of the sampling water environment.
[0046] When the environmental pollution source water quality sampler reaches the designated sampling location, the handle 201 is rotated. When the handle 201 rotates, it drives the take-up reel 202 fixed on it to start rotating. When the take-up reel 202 rotates, the lifting rope 203 fixed on it will start to be retrieved. As the lifting rope 203 is retrieved, the piston rod 204 fixed on its other end will be pulled upward. As the piston rod 204 rises, a negative pressure will be formed in the sampling tube 205. At this time, as a negative pressure is formed in the sampling tube 205, the multiple thin plastic sheets 206 fixed at the bottom of the sampling tube 205 will be sucked inward and bent. At the same time, water outside the environmental pollution source water quality sampler will also be sucked into the sampling tube 205, thus achieving the effect of fixed-point sampling.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
