Description

Technical Field

[0001] The invention relates to the technical field of water sample collection, in particular to a water quality collection and detection device. Background Art

[0002] Environmental protection requires regular water quality testing. Through water quality testing, we can accurately understand the status of various physical, chemical and biological indicators in the water, thereby evaluating the quality of the water. We can promptly discover water pollution problems and take appropriate control measures to prevent further deterioration of pollution. We can also understand the toxic effects of pollution on aquatic organisms such as fish, shellfish, and algae, and take measures to protect the living environment of aquatic organisms.

[0003] At present, water quality testing includes multiple items, such as water temperature, color, turbidity, smell and taste, solid matter, pH value, hardness, alkalinity, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, total organic carbon, etc. Among them, water temperature, pH value, dissolved oxygen, conductivity, etc. can be tested at the sampling site, and other items need to be brought into the laboratory for testing using experimental equipment.

[0004] In order to bring the sample liquid to be tested back to the laboratory, the staff is required to use the sampling equipment in the sampling area to lift part of the sample liquid and put the part of the sample liquid into the bottle. At present, the commonly used sampling equipment is mostly a sampling cylinder, that is, a cylinder suspended by a rope for extracting deep well liquid. Its specific structure can refer to a Chinese patent with publication number CN109357913A, which discloses a culture seawater sampler, including a base, a cylinder arranged on the base, a cylinder cover and a sealing cap matched with the cylinder, the cylinder cover is provided with a filter hole, the bottom of the base is provided with a counterweight block, the upper part of the cylinder is provided with a handle, the handle is connected with a pulling rope, the lower part of the cylinder is provided with a water outlet, and the outlet of the water outlet is provided with a water outlet cap. The upper part of the inner wall of the cylinder is provided with a limiting convex ring along the circumferential direction, and the gap between the limiting convex rings forms a water inlet.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0032] Example 1

[0033] In order to facilitate sampling personnel to collect liquid from the river water without spending time looking for a carrying ship, the present embodiment provides a new water sample collection device, which can float on the liquid surface and move to the position where water samples need to be collected. At the same time, the water sample of the device is extracted under the action of the device. After the water sample is extracted, the water sample can be returned and put into a bottle and taken back to the laboratory. The specific technical scheme of the device is shown below.

[0034] like Figure 1 , Figure 3As shown, the water sample collection device includes a support frame 1, and floating devices are arranged below and on the side of the support frame 1. The floating devices can support the support frame 1 to float on the liquid surface. A propeller 4 is also arranged on the side of the support frame 1, and the propeller 4 is arranged as a ducted fan propeller. At the same time, a mounting frame 3 is also arranged above the support frame 1, and a battery, a control box 31 and a lifting frame 8 are arranged on the mounting frame 3. The battery is connected to the control box 31, and the control box 31 is connected to the power device of the device, so the movement of the device can be controlled by the control box 31. In addition, the control box 31 can be wirelessly connected to a remote control, so that a staff member can also operate the movement of the device on the shore. The lifting frame 8 can be raised and lowered relative to the mounting frame 3. A sampling barrel 6 is arranged below the mounting frame 3, and the lower end of the sampling barrel 6 can be immersed in the liquid. During the descent of the sampling barrel 6, river water enters the sampling barrel 6, and when the sampling barrel 6 rises, the liquid sample remains in the sampling barrel 6.

[0035] The control box 31 and the wireless connection are both existing technologies and will not be described in detail. Here, the control box 31 is briefly introduced, that is, the control box 31 includes a display screen, control buttons and switches, circuit breakers, contactors, relays, controllers, etc. Therefore, the movement and operation of the device can be completely controlled by the control box 31.

[0036] like Figure 2 , Figure 8 , Fig. 9 As shown, in order to achieve stable floating of the device on the liquid surface, the support frame 1 includes an outer ring plate, an inner ring plate, a first internally threaded tube 11 and a support tube 13. The inner ring plate is connected and installed in the outer ring plate through a connecting plate 12. A plurality of first internally threaded tubes 11 are provided and are evenly distributed on the outside of the outer ring plate. One support tube 13 is provided and is located between the two first internally threaded tubes 11 and is fixedly connected to the outer ring plate. At the same time, the floating device includes a first floating device 2 and a second floating device 5. The first floating device 2 is set as an annular cavity structure. A plurality of clamps 21 are sleeved on the first floating device 2. A connecting plate 22 is fixedly set on the top of the clamp 21. The connecting plate 22 is connected by bolts and is set on the side of the connecting plate 12. Therefore, the first floating device 2 is stably installed below the inner ring plate and the outer ring plate, and it is convenient to disassemble according to needs. The second floating device 5 is set as a spherical cavity structure. The second floating device 5 is distributed on the outside of the support frame 1. The top of the second floating device 5 is fixedly set with a first threaded column 51. The first threaded column 51 is threaded through the first internal threaded tube 11. Therefore, under the cooperation of the first threaded column 51 and the first internal threaded tube 11, the second floating device 5 is stably installed on the outside of the support frame 1, and cooperates with the second floating device 5 to make the device stably float on the liquid surface. In addition, the position of the second floating device 5 relative to the support frame 1 can be adjusted by rotating the first threaded column 51.

[0037] like Figure 1As shown in the figure, in order to adjust the moving direction of the device according to requirements, a shaft body is fixedly arranged on the side of the propeller 4. The shaft body is connected through a bearing and penetrates through the support tube 13. A first motor 41 is arranged on the top of the support tube 13. The output shaft of the first motor 41 is connected to the shaft body, and the first motor 41 is connected to the control box 31. Therefore, under the control of the control box 31, the first motor 41 works to change the orientation of the propeller 4, and thus the moving direction of the device can be adjusted. The number and distribution of the propellers 4 can be determined according to actual requirements.

[0038] As Figure 4 , Figure 5 shown in the figure, in order to realize the lifting of the lifting frame 8, the lifting frame 8 includes a plate body, a limiting rod 82 and a second threaded column 83. The plate body is arranged in a T-shaped structure. The limiting rod 82 and the second threaded column 83 are both arranged above the plate body. The mounting frame 3 is arranged in a U-shaped structure, and a limiting hole 33 and a second internal threaded tube 36 connected through a bearing are arranged on the top. The end of the second internal threaded tube 36 is connected to the output shaft of the second motor 32 through a sprocket and a chain. The second motor 32 is connected to the control box 31. The limiting rod 82 penetrates through the limiting hole 33, and the second threaded column 83 is threadedly penetrated through the second internal threaded tube 36. Therefore, the plate body is stably and movably arranged below the mounting frame 3. In addition, by the operation of the second motor 32, the rotation of the second internal threaded tube 36 can be controlled, forcing the second threaded column 83 to lift and change the position of the plate body.

[0039] As Figure 6 shown in the figure, in order to extract the liquid sample during the lifting of the lifting frame 8, a connecting bolt 63 is penetrated through the side of the top of the sampling cylinder 6, and the sampling cylinder 6 is located below the plate body. The end of the connecting bolt 63 is threadedly inserted into the threaded groove of the plate body. Therefore, the sampling cylinder 6 is stably and detachably arranged below the lifting frame 8 and can move synchronously with the lifting frame 8. In addition, a liquid inlet hole 61 is arranged at the bottom of the sampling cylinder 6, and a closing cover 62 is hinged to the inner bottom. The closing cover 62 can cover the liquid inlet hole 61. During the descent of the sampling cylinder 6, the liquid passes through the liquid inlet hole 61 and enters the sampling cylinder 6. When the sampling cylinder 6 rises, the closing cover 62 blocks the liquid inlet hole 61 under the action of the liquid, and thus the liquid is retained in the sampling cylinder 6.

[0040] As Figure 4 shown in the figure, in order to stably install the battery and the second motor 32, a supporting ring plate 37 and a supporting frame 34 are arranged on the side of the mounting frame 3. A threaded rod is penetrated through the supporting frame 34, and a pressing disc 35 is installed at the end of the threaded rod. The second motor 32 is installed on the supporting ring plate 37 through bolts. The battery is arranged on the supporting frame 34, and the pressing disc 35 presses against the side wall of the battery. Therefore, the battery is stably installed under the action of the pressing disc 35.

[0041] Embodiment 2

[0042] like Figure 5 , Figure 7 As shown, on the basis of Example 1, a detector 7 is further arranged below the mounting frame 3. The detector 7 is located on the side of the sampling tube 6 and includes a connecting rod 73, a mounting plate 71 and a plurality of sensors 72. The mounting plate 71 is vertically mounted below the connecting rod 73. The plurality of sensors 72 are respectively temperature sensors, PH sensors, etc., and are all arranged through the mounting plate 71 to achieve stable installation of the sensors 72. At the same time, the sensors 72 are electrically connected to the control box 31. In addition, a threaded hole 81 is arranged at the end of the plate body, and a thread is arranged at the top of the connecting rod 73, and the thread is inserted into the threaded hole 81. Therefore, under the action of the connecting rod 73, the sensor 72 is stably mounted relative to the lifting frame 8 and can be raised and lowered synchronously with the lifting frame 8. Therefore, when the sampling tube 6 extracts liquid, the sensor 72 can detect temperature, PH, etc.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
