Then, the winch 112 is unwound by the cooperation of the controller 107 and the battery 110. Then, the hook 115 drives one end of the steel wire rope to pass through the square hole inside the side of the box 101 and the semicircular hole composed of the half ring 105 and the U-shaped frame 104 in sequence. Then, the hook 115 and the safety buckle 117 are connected together.

[0042] In this embodiment, when the box body 101 needs to be stably fixed on the water area shore, the water sample collecting device is first moved to the water area shore where water collection is needed, then each iron bar 5 is rotated to a vertical angle with the corresponding shaft 4 as the rotation axis, when the four iron bars 5 are all rotated to be vertical, each iron bar 5 is fixed by the cooperation of the corresponding shaft 4, the corresponding two rubber rings 6 and the corresponding mounting block 3, then the four iron bars 5 are all inserted into the soil of the water area shore, so as to improve the stability of the water sample collecting device placed on the water area shore.

[0043] The effect and working principle of the whole mechanism are as follows: when water sample collection is needed, the water sample collection device is first moved to the water area shore where water collection is needed, then each iron bar 5 is rotated to a vertical angle around the corresponding rotating shaft 4, when the four iron bars 5 are all rotated to be vertical, each iron bar 5 is fixed under the cooperation of the corresponding rotating shaft 4, the corresponding two rubber rings 6 and the corresponding mounting block 3, then the four iron bars 5 are all inserted into the soil of the water area shore, so that the stability of the water sample collection device placed on the water area shore is improved, when the water sample collection device is stably placed on the water area shore, the box door 102 is first removed from the box body 101, then the sinking frame 111 and the components mounted on the sinking frame 111 are moved out of the inside of the box body 101, then the winch 112 is controlled to pay out the steel wire rope under the cooperation of the controller 107 and the storage battery 110, then one end of the steel wire rope is sequentially threaded through the square hole on one side of the box body 101 and the semicircular hole composed of the half ring 105 and the U-shaped frame 104 under the cooperation of the hook 115, then the hook 115 and the safety buckle 117 are connected together, when the safety buckle 117 and the hook 115 are connected, the two hand screws 116 are first loosened, then the length of the U-shaped frame 104 protruding from the two square tubes 118 is adjusted, then the two hand screws 116 are tightened to fix the moved U-shaped frame 104, then the sinking frame 111 and the components mounted on the sinking frame 111 are lowered into the water under the cooperation of the controller 107, the hook 115, the safety buckle 117, the fixed U-shaped frame 104, the half ring 105 and the winch 112, when the sinking frame 111 is lowered to a suitable position in the water, the winch 112 is paused to pay out the steel wire rope under the control of the controller 107, then the two electric valves 114 on one of the sampling bottles 113 are opened, then water in the water enters the corresponding sampling bottle 113, when the two electric valves 114 are opened for a period of time, the two electric valves 114 are directly closed under the control of the controller 107, then the above operation steps are repeated to lower the sinking frame 111 by a distance, then the two electric valves 114 on another sampling bottle 113 are opened under the control of the controller 107, then water in the water enters the corresponding sampling bottle 113, when the two electric valves 114 are opened for a period of time, the two electric valves 114 are directly closed under the control of the controller 107, then the sinking frame 111 and the components mounted on the sinking frame 111 are pulled out of the water under the cooperation of the controller 107, the winch 112, the hook 115, the fixed U-shaped frame 104, the half ring 105 and the safety buckle 117, then the hook 115 and the safety buckle 117 are separated, then the two electric valves 114 on the corresponding sampling bottle 113 are opened under the control of the controller 107, so that water samples of the required depth of the water area are obtained, when the steel wire rope paid out by the winch 112 is broken during the lowering of the sinking frame 111 in the water,At this point, the controller 107 simultaneously activates both electric fixing rods 204, causing the two moving ends of each electric fixing rod 204 to move away from their corresponding connecting parts 207. When both moving ends of the two electric fixing rods 204 have moved away from their corresponding connecting parts 207, the four springs 213 (e.g., Figure 7 As shown, when the two housings 208 are tightly fixed together on opposite sides, all four springs 213 are in a stretched state. With the cooperation of the four sliding grooves 212 and the four sliders 214, the two housings 208 move horizontally in opposite directions. At this time, the two oppositely moving housings 208, in cooperation with the anti-slip pads 205, the corresponding mounting brackets 203, the corresponding grooved blocks 217, and the corresponding set of rotating rods 206, cause the corresponding connecting parts 207 to rotate. Simultaneously, the two oppositely moving housings 208 also drive the sealing rings 211 connected to them to move. When the two housings 208 separate in the water, the automatic inflation ring 215 automatically and quickly inflates, forming an inflatable object similar to a lifebuoy. The inflatable object then rapidly emerges from the water. The inflatable object that emerges will, with the cooperation of the connecting rope 216 and the perforated block 209, allow the sinking frame 111 and the components installed on it to float to the surface of the water, thus preventing the loss of the water sample collection equipment. When the wire rope unwinding by the winch 112 does not break, the two electric fixing rods 204, auxiliary block 201, two mounting slots 202, two mounting brackets 203, two anti-slip pads 205, two grooved blocks 217, two sets of rotating rods 206, and two connecting parts 207 can ensure that the two contacting surfaces of the two housings 208 and the two contacting surfaces of the two sealing rings 211 are tightly pressed together, thus preventing water from entering between the two housings 208 when the housings 208 come into contact with water, thereby preventing the automatic inflation ring 215 from starting.

[0044] Among them, the automatic inflatable ring 215 is similar to the water rescue ring (automatic inflatable life ring) on ​​the market.

[0045] Among them, the battery 110, the motor on the winch 112, each electric valve 114 and each electric fixing rod 204 are electrically connected to the controller 107.

[0046] Among them, the controller 107 (PLC controller), the battery 110, the winch 112, the electric valve 114, the electric fixing rod 204 and the automatic air inflator 215 are all existing technologies, and their models can be selected according to the actual situation. They will not be explained in detail here.

[0047] Although the present application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be replaced by equivalent features, by those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
