Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0024] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0025] Reference Figures 1 to 4 As shown, a small multi-channel water sample collector includes a bracket 1, and the bracket 1 is fixed with a plurality of sampling devices 2. The sampling devices 2 include a driving member 21, a sampling tube 22 and a piston rod 23. One end of the piston rod 23 is embedded in and sealed with the sampling tube 22, and the other end of the piston rod 23 is controlled by the driving member 21 to move up and down. The bracket 1 is also fixed with a sealing barrel 11, and a battery and a controller electrically connected to the driving member 21 are fixed inside the sealing barrel 11. When the driving member 21 controls the piston rod 23 to move upward, the external water sample will be drawn into the sampling tube 22 for storage. When the driving member 21 controls the piston rod 23 to move downward, the external water sample will be discharged from the sampling tube 22, so as to facilitate the collection and cleaning of the water sample.

[0026] Water samples are collected through the piston rod 23 and the sampling tube 22 to ensure that the collected water samples will not leak due to changes in external pressure caused by changes in the water level depth.

[0027] Specifically, the sampling devices 2 are arranged in a circular array on the periphery of the bracket 1 along the central axis thereof, and a plurality of sampling devices 2 are arranged in series. When one of the sampling devices 2 fails, the remaining sampling devices can still work normally.

[0028] The bracket 1 includes an upper plate 12 and a lower plate 13, and the sealed barrel 11 is connected to the upper plate 12 and the lower plate 13, thereby ensuring the overall structural strength of the bracket 1.

When one of the sampling devices 2 is damaged, it can be disassembled and replaced separately.

[0030] The driving member 21 includes a motor 211, two spaced screw rods 212 and a lifting plate 213. The output end of the motor 211 is fixedly connected to a driving gear 2111, the screw rod 212 is fixedly connected to a driven gear 2121 meshing with the driving gear 2111, and the two ends of the screw rod 212 are respectively sleeved with bearings 214, and are rotatably connected to the upper support frame 3 and the lower support frame 4 through the two bearings 214, and the piston rod 23 is fixedly connected to the lifting plate 213. Through the cooperation of the two screw rods 212 and the lifting plate 213, the piston rod 23 can be driven to move up and down in a balanced and stable manner, which can prevent the piston rod 23 from being subjected to force on one side and the other end from seriously interfering with the sampling tube 22.

[0031] The lower support frame 4 includes a guide ring 41 and a limit ring 42. The sampling tube 22 passes through the guide ring 41 and is embedded in the limit ring 42. The sampling tube 22 can be positioned and fixed by the guide ring 41 and the limit ring 42 to prevent the sampling device 2 from falling off when water flow or fish schools hit the small multi-channel water sample collector of the utility model.

[0032] The lower support frame 4 further includes a first connection portion 43 connecting the guide ring 41 and the limit ring 42, a second connection portion 44 arranged perpendicular to the first connection portion 43, and a lower groove 45 is formed in the second connection portion 44, and the lower plate 13 is embedded in the lower groove 45. A reinforcing rib 46 is fixedly connected between the first connection portion 43 and the second connection portion 44.

Similarly, the upper support frame 3 includes a bolt 47 and a nut 48, and the bolt 47 passes through the upper slot 31 and the upper plate 12 and is locked and connected with the nut 48, thereby realizing a detachable connection between the sampling device 2 and the bracket 1.

[0035] As another embodiment, the driving member 21 is an electric cylinder, which is fixedly connected to the piston rod 23 via the electric cylinder, and the lifting and lowering of the piston rod 23 is controlled by the lifting and lowering of the output end of the electric cylinder.

[0036] The sampling device 2 is attached with a serial number label, and the controller controls the sampling device 2 to start sampling in sequence according to the sequence of the serial number label. The sampling device 2 is sampled in sequence by the serial number label, for example, sampling device 1 is used for sampling at a depth of 500 meters, and sampling device 2 is used for sampling at a depth of 1000 meters, to ensure that the water samples collected at different water depths correspond to the serial number labels of the sampling device 2 and will not be confused.

[0037] It also includes a water depth sensor, which is electrically connected to the controller. The small multi-channel water sample collector of the utility model is placed on an underwater walking device, wherein the underwater walking device can be an underwater walking robot or a submarine, etc. The small multi-channel water sample collector is driven by the underwater walking device to move underwater. During the underwater movement, the water depth sensor detects the depth and then feeds the signal back to the controller. Then, the controller controls the driving member 21 to work and start sampling according to the above depth detection signal when the small multi-channel water sample collector is at the set sampling depth.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
