Description

Technical Field

[0001] This utility model relates to the technical field of samplers, and specifically relates to a water quality sampler. Background Art

[0002] A water quality sampler is a professional device used to collect water samples from different water sources such as rivers, lakes, reservoirs, oceans, groundwater, industrial wastewater discharge outlets, and municipal sewage treatment plants. It is crucial for fields such as environmental monitoring, water resource management, public health, industrial production, and scientific research.

[0003] However, when we actually use it, the water quality sampler is used to sample the water in the lake and then send it to the laboratory for testing. Most of the samplers used for sampling are set up with measuring cups and suspension ropes, which can sink into the water for sampling. In order to better understand the water quality of the lake, it is necessary to sample different water layers to obtain accurate usage data. For this reason, it is necessary to use the measuring cup for sampling multiple times. However, the existing sampling requires multiple samplings, which is rather troublesome and leads to low detection efficiency. Therefore, we propose a water quality sampler. Summary of the Utility Model

[0004] One technical problem to be solved by this application is: how to design a water quality sampler that can quickly sample multiple water layers.

[0005] To solve the above technical problem, an embodiment of this application provides a water quality sampler, including a housing, a sealing housing arranged on the housing, a suspension rope arranged on the housing, and a plurality of water inlet holes opened on the side surface of the housing. It further includes:

[0006] A water storage cavity, which is arranged inside the housing, has a plurality of them, and is connected to the outside through the water inlet holes;

[0007] A wedge block, which is movably arranged inside the housing;

[0008] An inclined block, which is movably arranged inside the housing, and its inclined surface is movably arranged on the inclined surface of the wedge block;

[0010] A pushing component, which is arranged inside the water storage cavity and is used to drive the pushing component to move through the inclined block. The pushing component drives the piston plate arranged at the end face to pull the gas inside the water storage cavity, thereby sucking water through the water inlet holes.

[0011] In some embodiments, the pushing component includes a curved tube movably disposed inside the piston plate. A push rod is disposed on the side surface of the inclined block.

[0012] In some embodiments, a movable rod is disposed on the end surface of the piston plate. A first piston disk is disposed on the end surface of the movable rod away from the piston plate. The outer surface of the first piston disk is movably disposed inside the curved tube. A sealed space is provided between the second piston disk and the first piston disk inside the curved tube.

[0013] In some embodiments, a fixing ring is sleeved on the outer surface of the push rod. The top of the fixing ring is disposed on the inner wall of the water storage cavity. The end surface of the curved tube is disposed on the end surface of the fixing ring. A spring is sleeved on the outer surface of the push rod. Two ends of the spring are respectively disposed on the end surface of the fixing ring and the outer surface of the push rod. A one-way water flow component for blocking the self-entry of water flow into the water storage cavity is disposed inside the water inlet hole.

[0014] In some embodiments, the one-way water flow component includes a filter plate disposed on the inner wall of the water inlet hole. A water blocking disk is movably disposed on the end surface of the inner wall of the water storage cavity. A tension spring is provided between the filter plate and the water blocking disk.

[0015] In some embodiments, the driving component includes smooth rods disposed at both ends of the inner wall of the housing. The outer surface of the smooth rod is movably disposed inside the wedge block. A threaded rod is threadedly connected inside the wedge block. The bottom end of the threaded rod is movably disposed on the bottom of the inner wall of the housing. The top end of the threaded rod penetrates through the inner wall of the housing and extends into the inside of the sealed housing. A motor is disposed on the inner wall of the sealed housing. The output end of the motor is disposed on the top end of the threaded rod.

[0016] In some embodiments, a support component is disposed on the end surface of the movable rod for enabling the movable rod to support the piston plate to move inside the water storage cavity. The support component includes a moving plate disposed on the end surface of the movable rod. A plurality of L-shaped plates are disposed on the outer surface of the moving plate.

[0017] This utility model has at least the following beneficial effects:

[0018] 1. When the wedge block arranged inside the upper shell rises, it can act on the inclined block below, causing the inclined block to drive the pushing component to move. The pushing component can drive the piston plate to move inside the water storage cavity. Since the gas inside the water storage cavity has a fixed volume, it can drive the one-way water flow component to move, enabling water to be inhaled into the water storage cavity through the water inlet hole. The wedge block acts on multiple inclined blocks in sequence, increasing the working efficiency for water sampling at different water layers.

[0019] 2. When the movable rod pushes the piston plate, the arranged support component can push the piston plate through the support component, avoiding the situation where the movable rod only acts on one point of the piston plate and causing it to get stuck inside the water storage cavity. Therefore, the failure rate during use can be reduced. Description of the Drawings

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility. Obviously, the described embodiments are only a part of the embodiments of the present utility, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility without creative efforts shall fall within the protection scope of the present utility.

[0030] Embodiment 1

[0031] Please refer to Figure 1-7 , the present utility provides a technical solution:

[0032] A water quality sampler includes a housing 1, a sealing housing 2 provided on the housing 1, a suspension rope 3 provided on the housing 1, and a plurality of water inlet holes 4 opened on the side surface of the housing 1, and further includes:

[0033] A water storage cavity 7 is provided inside the housing 1, there are a plurality of them, and they are communicated with the outside through the water inlet holes 4;

[0034] A wedge block 5 is movably provided inside the housing 1;

[0035] An inclined block 6 is movably provided inside the housing 1, and its inclined surface is movably provided on the inclined surface of the wedge block 5. There is only one wedge block 5, and there are a plurality of inclined blocks 6, and they correspond to a plurality of water storage cavities 7 and water inlet holes 4;

[0036] A piston plate 11 is movably provided on the inner wall of the water storage cavity 7 for squeezing the air inside the water storage cavity 7;

[0037] A pushing assembly 8 is provided inside the water storage cavity 7, and is used to drive the pushing assembly 8 to move through the inclined block 6. The pushing assembly 8 drives the piston plate 11 provided on the end face to pull the gas inside the water storage cavity 7, so as to suck water through the water inlet hole 4.

[0038] The pushing assembly 8 includes a curved tube 81 movably provided inside the piston plate 11. A push rod 85 is provided on the side surface of the inclined block 6. A second piston disc 86 is provided on the end face of the push rod 85 away from the inclined block 6. The outer surface of the second piston disc 86 is movably provided on the inner wall of the curved tube 81. When the inclined block 6 moves, it can drive the push rod 85 to move. Therefore, the push rod 85 can drive the second piston disc 86 provided on the end face to move inside the curved tube 81, and push the gas inside the curved tube 81 to flow.

[0039] The end face of the piston plate 11 is provided with a movable rod 83. The end face of the movable rod 83 away from the piston plate 11 is provided with a first piston disc 82. The outer surface of the first piston disc 82 is movably arranged inside the curved pipe 81. Then, a sealed space is arranged between the second piston disc 86 and the first piston disc 82 inside the curved pipe 81, forming a sealed space that can make the displacement distances of the push rod 85 and the movable rod 83 the same.

[0040] A fixed ring 84 is sleeved on the outer surface of the push rod 85. The top of the fixed ring 84 is arranged on the inner wall of the water storage cavity 7. The end face of the curved pipe 81 is arranged on the end face of the fixed ring 84. A spring 87 is sleeved on the outer surface of the push rod 85. The two ends of the spring 87 are respectively arranged on the end face of the fixed ring 84 and the outer surface of the push rod 85. A one-way water flow component 9 for blocking the self-entry of water flow into the water storage cavity 7 is arranged inside the water inlet hole 4. The arranged spring 87 can reset the push rod 85 after the water inhalation is completed.

[0041] The one-way water flow component 9 includes a filter plate 91 arranged on the inner wall of the water inlet hole 4. A water blocking disc 93 is movably arranged on the end face of the inner wall of the water storage cavity 7. A tension spring 92 is arranged between the filter plate 91 and the water blocking disc 93. A driving component 10 for driving the wedge block 5 to drive a plurality of inclined blocks 6 to move is arranged on the wedge block 5. The arranged water blocking disc 93 can unidirectionally block the water flow. The arranged tension spring 92 can play a limiting role for it. The tension spring 92 can be replaced according to a water layer with a higher depth to prevent the water from entering the water storage cavity 7 in advance due to excessive water pressure.

[0042] The driving component 10 includes optical rods 103 arranged at both ends of the inner wall of the housing 1. The outer surfaces of the optical rods 103 are movably arranged inside the wedge block 5. A threaded rod 102 is threadedly connected inside the wedge block 5. The bottom end of the threaded rod 102 is movably arranged at the bottom of the inner wall of the housing 1. The top end of the threaded rod 102 penetrates through the inner wall of the housing 1 and extends into the sealed housing 2. A motor 101 is arranged on the inner wall of the sealed housing 2. The output end of the motor 101 is arranged at the top end of the threaded rod 102. By rotating the threaded rod 102, the wedge block 5 can be driven to lift inside the housing 1, and the arrangement of the optical rods 103 plays a guiding role for the wedge block 5.

[0043] When using this device, first, the housing 1 needs to be lowered to the water layer where sampling is required through the lifting rope 3. After reaching the water layer, the motor 101 can be remotely controlled to start. The output end of the motor 101 drives the threaded rod 102 to rotate. The threaded rod 102 drives the wedge block 5 connected to its outer surface to move. The wedge block 5 slides and rises on the outer surface of the optical rod 103. The inclined surface of the wedge block 5 contacts the inclined surface of the inclined block 6, thereby driving the inclined block 6 to move. The inclined block 6 drives the push rod 85 arranged on its side to move. The push rod 85 drives the second piston disc 86 arranged on its end face to move inside the curved tube 81, and at the same time squeezes the spring 87. Therefore, the second piston disc 86 squeezes the gas inside the curved tube 81, so that the gas inside the curved tube 81 pushes the first piston disc 82 movably arranged inside the curved tube 81 to move. The first piston disc 82 drives the movable rod 83 arranged on its end face to move. The movable rod 83 drives the piston plate 11 arranged on its end face to slide inside the water storage cavity 7. Since the volume of the gas inside the water storage cavity 7 is fixed, the water blocking disc 93 is driven to move, and the tension spring 92 arranged on the end face of the water blocking disc 93 is deformed. The water arranged inside the water inlet hole 4 will enter the water storage cavity 7. When the wedge block 5 moves away from the inclined block 6, the spring 87 drives the movable rod 83 to reset. Therefore, the piston plate 11 can be driven to reset. The piston plate 11 squeezes the water inside the water storage cavity 7. At the same time, the tension spring 92 drives the water blocking disc 93 to reset, preventing the water that has entered the water storage cavity 7 from flowing out. Therefore, multiple inclined blocks 6 can be successively pushed for multiple samplings.

[0044] Embodiment 2

[0045] Please refer to Figure 8 , this utility model provides a technical solution:

[0046] Different from Embodiment 1, a support assembly 12 is arranged on the end face of the movable rod 83 for enabling the movable rod 83 to support the piston plate 11 to move inside the water storage cavity 7. The support assembly 12 includes a movable plate 121 arranged on the end face of the movable rod 83. A plurality of L-shaped plates 122 are arranged on the outer surface of the movable plate 121. Fixed discs 123 are arranged on the end faces of the plurality of L-shaped plates 122. The end faces of the plurality of fixed discs 123 are all arranged on the side of the piston plate 11.

[0047] When the gas inside the curved tube 81 is pushed by the push rod 85, the movable rod 83 can be driven to move. The end face of the movable rod 83 will first act on the movable plate 121. The force is dispersed to the plurality of L-shaped plates 122 through the movable plate 121, and finally transmitted to the fixed discs 123 through the plurality of L-shaped plates 122, so that the force can be evenly distributed on the end face of the piston plate 11.
