For example, some samplers are complicated and inconvenient to operate when adjusting the sampling depth, resulting in low sampling efficiency. Utility Model Content

[0004] To address the problem of complex and inconvenient operation when adjusting the sampling depth of water samplers, which leads to low sampling efficiency, this application provides a convenient water sampler.

[0005] The portable water sampler provided in this application adopts the following technical solution:

[0006] A portable water sampler includes a support frame, a base, a conduit, a weight-bearing base, and a water pressure sensor. The base is rotatably mounted on the support frame. One end of the conduit extends into the base, and the other end of the conduit and the water pressure sensor are both fixed to the base through the weight-bearing base. The base includes a housing, a first cover, a control circuit board, a water pump, and a second cover. Openings are formed on opposite sides of the housing, and the first and second covers are detachably mounted to the two openings of the housing, respectively. The water pumps are all installed in the inner cavity of the housing. The conduit section includes a sheath tube, a water pipe, and a wire. The sheath tube is a flexible tube with through holes on the outer wall at both ends. The water pipe and the wire are both inserted into the sheath tube. The two ends of the wire pass through the adjacent through holes, and the upper and lower ends of the wire are electrically connected to the control circuit board and the water pressure sensor, respectively. The two ends of the water pipe pass through the two ends of the sheath tube, and the upper end of the water pipe is connected to the water pump input end. The sheath tube is coiled around the outside of the base, and the lower end of the sheath tube and the weight-adding seat both extend to the bottom of the support frame.

[0007] Furthermore, the portable water sampler also includes an auxiliary tube placement section installed on a support frame. The sheath tube passes through the auxiliary tube placement section, and the auxiliary tube placement section adjusts the extension and retraction state of the sheath tube on the base. The auxiliary tube placement section includes a connecting frame, a main tube placement wheel, and a secondary tube placement wheel. The connecting frame is fixedly connected to the support frame. The main tube placement wheel and the secondary tube placement wheel are rotatably connected to the inside of the connecting frame. The sheath tube passes through the gap between the main tube placement wheel and the secondary tube placement wheel, and the outer wall of the sheath tube contacts the outer walls of the main tube placement wheel and the secondary tube placement wheel, respectively. The connecting frame is located below the base, and a notch is formed at the top of the connecting frame. The bottom of the base can movably pass through the notch.

[0008] Furthermore, positioning and mounting rings are formed on both opposite sides of the inner wall of the housing. The first cover and the second cover are respectively fixed to the two positioning and mounting rings by bolts. Two protective retaining rings are also formed on the outer wall of the housing. There is a gap between the two protective retaining rings, and the sheath is coiled on the outer wall of the housing and located between the two protective retaining rings.

Detailed Implementation

[0018] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This application discloses a portable water sampler. (Refer to...) Figure 1 and Figure 2 The portable water sampler may include a support frame 10, a base 20, a guide tube 30, a weight-bearing base 40, a water pressure sensor, and an auxiliary tube placement section 50. The base 20 is rotatably mounted on the support frame 10. One end of the guide tube 30 extends into the base 20, while the other end of the guide tube 30 and the water pressure sensor pass through and are fixed to the weight-bearing base 40. The guide tube 30 is coiled around the base 20. The auxiliary tube placement section 50 is mounted on the support frame 10 and is used to adjust the overall extension and retraction of the guide tube 30 on the base 20, allowing the lower end of the guide tube 30 and the weight-bearing base 40 to penetrate deep into the water body to be sampled.

[0020] In this embodiment, the support frame 10 can be made into the required shape by cutting and welding profiles or steel plates, and is used to support and install corresponding components.

[0021] See Figure 3The base portion 20 includes a housing 21, a first cover 22, a control circuit board 23, a water pump 24, a second cover 25, and a handle 26. Openings are formed on opposite sides of the housing 21, and positioning rings 211 are formed on opposite sides of the inner wall of the housing 21. The first cover 22 and the second cover 25 are respectively bolted to the two positioning rings 211, so that the two openings of the housing 21 are respectively covered by the detachable first cover 22 and the second cover 25. Two protective retaining rings 212 are also formed on the outer wall of the housing 21, with a gap between them. The sheath 31 in the guide tube portion 30 is coiled around the outer wall of the housing 21 and positioned between the two protective retaining rings 212, allowing the two protective retaining rings 212 to limit the winding and unwinding of the guide tube portion 30. Both the control circuit board 23 and the water pump 24 are housed within the inner cavity of the housing 21. The first cover 22 has several mounting posts 221 on its side facing the housing 21. The control circuit board 23 and the water pump 24 are connected to these mounting posts 221 using bolts, ensuring both are installed within the inner cavity of the housing 21. The second cover 25 is equipped with a display screen 251 and a button 252. Both are electrically connected to the control circuit board 23. The display screen 251 shows the preset depth position and the actual depth position. The button 252 is used to adjust the preset depth and activate the water pump 24 in conjunction with the control circuit board 23. The control circuit board 23 can be equipped with a microcontroller as a controller. There are no particular limitations on the controller; other existing control technologies can also be used, which will not be elaborated upon here. A drain pipe 253 is also inserted into the second cover 25. One end of the drain pipe 253 is connected to the output end of the water pump 24, and the other end of the drain pipe 253 extends to the outside of the second cover 25, so that the extracted water sample can be discharged through the drain pipe 253. A handle 26 is installed on the protective retaining ring 212, so that the device can be moved by lifting the handle 26 when it needs to be moved.

[0022] See Figure 4The conduit section 30 includes a sheath tube 31, a water pipe, and a wire 32. The sheath tube 31 is a flexible tube with through holes on the outer wall at both ends, and both the water pipe and the wire 32 pass through the sheath tube 31. The two ends of the wire 32 pass through adjacent through holes, and the upper and lower ends of the wire 32 are electrically connected to the control circuit board 23 and the water pressure sensor, respectively. This allows the water pressure sensor to feed back the water pressure signal collected after it is immersed in water to the control circuit board 23, and the depth position can be calculated based on the water pressure. The two ends of the water pipe pass through the two ends of the sheath tube 31, and the upper end of the water pipe is connected to the input end of the water pump 24, while the lower end of the water pipe is used to extract water samples. The sheath tube 31 is coiled around the outside of the base part 20, and the lower end of the sheath tube 31 and the weight-adding seat 40 both extend to the bottom of the support frame 10. This allows the base part 20 to rotate the sheath tube 31, so that the lower end of the sheath tube 31 and the weight-adding seat 40 can be submerged in the water or moved upward out of the water source.

[0023] In this embodiment, the weight-adding seat 40 can be made of metal to increase the load on the conduit section 30, thereby making it easier for the lower end of the conduit section 30 to penetrate deeper into the water source.

[0024] In this embodiment, the water pressure sensor typically consists of a sensing element and a conversion element. Its working principle is that the pressure of the water being measured acts directly on the diaphragm of the sensor, causing a micro-displacement of the diaphragm proportional to the water pressure, thereby changing the sensor's resistance value. This change is detected by electronic circuitry and converted into a standard measurement signal corresponding to the pressure. Water pressure sensors are commonly used components in existing technology and will not be described in detail here.

[0025] See Figure 5 The auxiliary pipe-laying unit 50 includes a connecting frame 51, a main pipe-laying wheel 52, and a secondary pipe-laying wheel 53. The connecting frame 51 is fixedly connected to the support frame 10, and a notch 511 is formed at the top of the connecting frame 51. The bottom of the base part 20 can movably pass through the notch 511 to avoid interference. The main pipe-laying wheel 52 and the secondary pipe-laying wheel 53 are both rotatably connected to the inside of the connecting frame 51. The sheath tube 31 passes through the gap between the main pipe-laying wheel 52 and the secondary pipe-laying wheel 53, and the outer wall of the sheath tube 31 contacts the outer walls of the main pipe-laying wheel 52 and the secondary pipe-laying wheel 53, respectively, so that the sheath tube 31 can be moved by the friction force of the rotation of the main pipe-laying wheel 52 and the secondary pipe-laying wheel 53. In addition, the main pipe-laying wheel 52 can also be driven to rotate by a motor, so that the auxiliary pipe-laying unit 50 can automatically drive the lower end of the sheath tube 31 into the water.

[0026] When using this portable water sampler, the desired sampling depth can be preset using button 252. Then, the lower end of the guide tube 30, the weight base 40, and the water pressure sensor are lowered into the water source using the auxiliary tube placement section 50. The user can observe the display screen 251. Once the actual depth matches the preset depth, the water pump 24 can be activated, and the water sample can be extracted using the water pipe.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
