Description

Technical Field

[0001] This utility model relates to the field of water environment detection technology, and in particular to a water pollution detection sampler. Background Technology

[0002] Water sources are the general geographical term for the origin and form of water. Water sources are the source of life, an important intermediary for the transmission of matter, information, and energy, and an irreplaceable resource for the survival of organisms on the Earth's surface. Water sources mainly exist in areas such as oceans, rivers, lakes, glaciers, and snow-capped mountains. They are renewed through atmospheric movement and other forms. Water sources are a precious resource that humans cannot do without in their production and daily life activities. Water is the source of life and an indispensable material basis for human survival. Therefore, water is closely related to our daily lives. Since water is so important in our lives, we have the need to prevent the pollution and waste of water sources from the source.

[0003] Current water quality samplers often struggle to monitor multiple water sources. Traditional samplers can only take samples from one location, resulting in inaccurate and incorrect results. Therefore, improving and refining these methods is a pressing technical issue that needs to be addressed. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] Please refer to Figures 1 to 7 This utility model provides a technical solution:

[0030] A water pollution detection sampler, comprising

[0031] The negative pressure unit 10 includes an upper housing 11, which is disposed on the top of the sampler. A negative pressure pump (existing technology, not shown in the figure) is fixedly connected inside the upper housing 11 to provide negative pressure energy to the sampler, and a mounting frame 16 is fixedly connected to the bottom of the upper housing 11.

[0032] There are multiple sampling bottles 30, which are vertically mounted on the mounting frame 16. Each bottle includes a bottle body 33, with a bottle cap 31 screwed to the upper end of the bottle body 33. An air outlet 32 ​​and a water inlet 34 are fixedly connected to the left and right sides of the bottle body 33, respectively. Plugs are provided on the air outlet 32 ​​and the water inlet 34. The air outlet 32 ​​is connected to the air inlet of the negative pressure pump through the negative pressure pipe 50, and the water inlet 34 is connected to the sampling tube 40.

[0033] The bottom housing 20 is engaged at the bottom of the upper housing 11 to protect the sampling bottle 30 and prevent it from being damaged by collision during use.

[0034] In the above process, the air in the bottle 33 is extracted by a negative pressure pump, creating a negative pressure inside the bottle 33. Wastewater is then drawn into the bottle 33 through the sampling tube 40, thereby achieving wastewater sampling. After sampling, the air outlet 32 ​​and the water inlet 34 are blocked by a plug. By using multiple sampling bottles 30, wastewater sampling can be achieved from different water areas, solving the problem that the wastewater sampler can only collect wastewater from one water area.

[0035] In this plan, such as Figure 3 As shown: The mounting frame 16 has multiple mounting slots 17 corresponding to the sampling bottle 30. The mounting frame 16 is connected to the sampling bottle 30 through the mounting slots 17, which makes it easy to take the sampling bottle 30 out.

[0036] In this plan, such as Figure 3 As shown: The negative pressure tube 50 includes a second hose 51. One end of the second hose 51 is fixedly connected to the air inlet of the negative pressure pump, and the other end of the second hose 51 is fixedly connected to a second connector 52. The second connector 52 is spirally connected to the air outlet 32. Thus, the second hose 51 can be connected to different bottles 33 through the provided second connector 52.

[0037] In this plan, such as Figure 3 As shown: A control button 12 is provided on the upper housing 12. The control button 12 is electrically connected to the negative pressure pump and is used to manually control the switch of the negative pressure pump.

[0038] In this plan, such as Figure 3 As shown: The bottom of the upper housing 12 is fixedly connected with a reinforcing block 14 corresponding to the clearance groove 22. When the outer shell 21 is engaged with the upper housing 12, the reinforcing block 14 is installed at the top of the clearance groove 22 to strengthen the outer shell 21 and prevent the outer shell 21 from colliding during use, causing deformation of the upper end of the outer shell 21.

[0039] In this plan, such as Figure 4 As shown: The bottom housing 20 includes an outer shell 21. Both sides of the outer shell 21 are provided with clearance grooves 22 to allow passage of the air outlet 32 ​​and the water inlet 34. Elastic locking blocks 23 are symmetrically fixedly connected to the upper end of the outer shell 21. A locking block 15 corresponding to the elastic locking block 23 is fixedly connected to the bottom of the upper housing 11. Figure 3 In the middle, the elastic locking block 23 engages with the locking block 15, thus facilitating the connection between the upper housing 11 and the outer housing 21 and protecting the sampling bottle 30.

[0040] In this plan, such as Figure 5As shown: the sampling tube 40 includes a hose 42, one end of which is fixedly connected to a connector 41. The hose 42 is connected to the inlet head 34 through the connector 41, and the other end of the hose 42 is fixedly connected to a filter head 44 to prevent impurities in the sewage from entering the sampling bottle 30 and affecting the accuracy of subsequent testing. A float ball 43 is fixedly connected to the outer surface of the hose 42 to ensure the sinking distance of the hose 42 inlet and ensure the consistency of testing.

[0041] In this plan, such as Figure 7 As shown: A water level sensor 35 is fixedly connected inside the bottle body 31. The water level sensor 35 is preferably a wireless water level sensor. The water level sensor 35 is electrically connected to the negative pressure pump through a controller. When the water level reaches a certain height, the negative pressure pump stops working. The water level sensor 35 is located below the air outlet 32 ​​and the water inlet 34 to prevent water from flowing out when the connector 1 41 and connector 2 52 are removed.

[0042] Working principle: When wastewater sampling is required, connect the negative pressure tube 50 and sampling tube 40 to one of the sampling bottles 30, start the negative pressure pump, which will draw air out of the sampling bottle 30 through the negative pressure tube 50, thereby creating a negative pressure environment inside the bottle. This negative pressure environment drives the wastewater into the sampling bottle 30. At the same time, the filter head 44 is immersed in the wastewater to effectively prevent impurities from entering and ensure the purity of the sample. As the negative pressure continues to act, the wastewater enters the sampling bottle 30 through the sampling tube 40 and the inlet head 34 until it reaches the preset water level. At this time, the water level sensor 35 will detect the water level change and automatically shut off the negative pressure pump through the controller to prevent the water sample from overflowing. After one collection is completed, connect the negative pressure tube 50 and sampling tube 40 to the next sampling bottle 30 to perform a second sampling. Sampling can be performed on water bodies in different locations, which is convenient and practical. After sampling, remove the outer shell 21, take out the entire sampling bottle 30, remove the bottle cap 31, pour the wastewater sample into the test tube, and the test can be performed. This provides technical support for water quality monitoring and environmental protection.

[0043] It should be noted that the upper housing 11 should be provided with a vent hole for ventilation when the negative pressure pump is working. This is an existing technology and will not be described in detail here.
