Description

Technical Field

[0001] The utility model mainly relates to the technical field of liquid sampling, and in particular to a liquid sampling metering and detecting device. Background Art

[0002] In the sampling, testing and judging operations of natural water bodies, since the measurement and testing requires sampling in water bodies at different depths, and fixed-point sampling operations need to be carried out in different areas of the sampling waters, it is generally necessary to manually drive the boat into the sampling point to carry out sampling operations. Due to the waterway restrictions of natural waters, there are some waters that are not accessible to ships normally, which makes it inconvenient to manually drive boats to sample natural waters.

[0003] The inventor proposed a liquid sampling, metering and detection device, which, by setting up a small remote-controlled hull, prevents the waves caused by a large hull entering the sampling waters from affecting the sampling results of shallow waters. At the same time, a stratified sampling device is mounted on the small remote-controlled hull to perform stratified sampling operations in natural water bodies. Utility Model Content

[0039] See attached Figure 1-4 The utility model provides a liquid sampling metering and detection device, comprising the following structure:

[0040] The connecting pipe 1 has an extension frame 11 fixedly disposed on the outer side of the connecting pipe 1 , and an underwater propeller 12 fixedly disposed on the bottom of the extension frame 11 .

[0041] The mounting seat 4 has a plurality of three-section telescopic guide rails 5 fixedly disposed in the middle thereof, a mounting frame 6 fixedly disposed on the top of the outer guide rail of the telescopic guide rail, and a sliding seat 7 slidably connected to the middle of the inner guide rail of the three-section telescopic guide rail 5.

[0042] The frame 8 has a plurality of sampling barrels 9 fixedly disposed on the left side of the frame 8 from top to bottom.

[0043] In this embodiment, Figure 1 and Figure 2 As shown, a first buoyancy reserve ring 2 and a second buoyancy reserve ring 3 are respectively fixed to the top and the bottom of the connecting pipe 1 , and the connecting pipe 1 is symmetrically arranged about the middle of the first buoyancy reserve ring 2 .

[0044] The first buoyancy reserve ring 2 and the second buoyancy reserve ring 3 serve as the buoyancy reserve structure of the device, completing the floating setting of the device on the water surface, cooperating with the underwater propeller 12 installed on the extension frame 11 to move in the water, so as to facilitate the movement of the device between various sampling points.

[0045] In this embodiment, Figure 1 and Figure 2 As shown, the bottom of the mounting seat 4 is clamped with the middle of the first buoyancy reserve ring 2, a balancing pipe 41 is fixedly provided in the middle of the mounting seat 4, the bottom of the balancing pipe 41 extends to the bottom of the second buoyancy reserve ring 3, and a counterweight block 42 is fixedly provided at the bottom of the balancing pipe 41.

[0046] Through the design of the trim tube 41 and the counterweight 42, wherein the counterweight 42 extends from the bottom of the trim tube 41 to the bottom of the second buoyancy reserve ring 3, the floating stability of the device on the water surface is improved.

[0047] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a driving motor 61 is fixedly provided on the top front side of the mounting frame 6, a shaft rod 62 is fixedly provided on the rear output end of the driving motor 61, the front and rear ends of the shaft rod 62 are movably connected to the top front and rear sides of the mounting frame 6 respectively, a wire roller 63 is fixedly provided in the middle part of the shaft rod 62, and a cable 64 is wound around the outer side of the wire roller 63.

[0048] The driving motor 61 cooperates with the shaft 62 to drive the wire roller 63 to rotate, completing the retraction and release of the cable 64. During the retraction and release process, the cable 64 moves the shaft 62 to complete the release and recovery of the slide 7 on the three-section telescopic guide rail 5.

[0049] In this embodiment, Figure 3 and Figure 4 As shown, the left side of the slide 7 is fixedly connected to the top right side of the frame 8 , a lifting ring 71 is fixedly provided on the top of the slide 7 , and the outer side of the lifting ring 71 is fixedly connected to one end of the cable 64 .

[0050] The slide 7 cooperates with the lifting ring 71 and is lifted and lowered under the drive of the cable 64. The slide 7 and the frame 8 slide outside the three-section telescopic guide rail 5. At this time, the three-section telescopic guide rail 5 extends toward the underwater under the drive of the slide 7, thereby improving the lifting stability of the frame 8 and completing the sampling operation of the sampling barrel 9 on the frame 8 extending into different depth sampling layers underwater.

At this time, the water pressure sensor 93 cooperates with the control box 92 to complete the closing of the solenoid valve 91 to prevent water samples from non-sampling layers from mixing into the sampling bucket 9.

[0053] Since the equipment needs to be extended underwater for sampling operations, when customizing the equipment, the control box 92 and other related circuits need to be waterproofed.

[0054] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
