[0031] In the present embodiment, when it is necessary to collect the beverage in the storage tank, the sampling device body 1 can be vertically placed in the storage tank first, and then the sampling device body 1 can be driven to sink in the storage tank by the counterweight 113. After the sampling device body 1 sinks to a suitable position, the motor 111 can be turned on through the power supply system of the motor 111, so that when the motor 111 rotates forward, the rack 108 is driven to move through the gear 112, so that the rack 108 drives the slider 110 to slide downward in the slide groove 109 during the movement, thereby causing the rack 108 to move downward, and while the rack 108 slides downward, it drives the bottle cap 106 and the sealing ring 105 to descend synchronously through the connecting column 107, so that the bottle cap 106 is separated from the feeding pipe 101 to be opened, thereby allowing the beverage to pass through the feeding pipe 101. 1 enters the interior of the sampling bottle 102, and the reverse running motor 111 drives the bottle cap 106 and the sealing ring 105 to rise and close with the feeding pipe 101. After taking out the sampling device body 1, the sampling device body 1 is placed horizontally to the right, and the one-way valve 104 is opened to make the beverage sample in the sampling bottle 102 flow out of the material pipeline 103 to the interior of the sampling device body 1 for sampling. Through the sampling device body 1, when the device is put into the storage tank to sample the beverage, the device can store beverages of different depths through the arrangement of three sampling bottles 102, which greatly saves the cumbersomeness of the staff's operation and improves the staff's labor efficiency. Through the arrangement of the sealing ring 105, the closing degree of the bottle cap 106 and the feeding pipe 101 can be increased, and the sealing performance of the device can be increased.

[0032] Embodiment 2, as Figure 1-4 As shown, a connecting rope 2 is fixedly installed at the top center of the sampling device body 1, a capstan 201 is movably embedded in the inner surface of the connecting rope 2, a rotating shaft 202 is movably embedded in the inner center of the capstan 201, a crank 203 is fixedly installed on the right side of the rotating shaft 202, support columns 204 are movably sleeved on both sides of the outer surface of the rotating shaft 202, and a connecting plate 205 is fixedly installed on the bottom of the two support columns 204.

[0033] In this embodiment, the staff can first fix the connecting plate 205 on the top of the storage tank, and then turn the crank handle 203 forward to drive the winch 201 to rotate through the rotating shaft 202 embedded in the support column 204, and pay out the connecting rope 2 sleeved on its outer surface, thereby driving the sampling device body 1 to descend, and then through the counterweight block 113, through its own gravity, drive the sampling device body 1 to sink vertically in the storage tank for sampling, and through the cooperation of the linkage structure such as the connecting rope 2 and the rotating shaft 202, the device can be applied to storage tanks of different depths, which greatly increases the applicability of the device.

[0034] Working principle: When it is necessary to collect beverages in a storage tank, the sampling device body 1 can be placed vertically in the storage tank first, and then the sampling device body 1 can be driven to sink in the storage tank by the counterweight 113. When the sampling device body 1 sinks to a suitable position, the motor 111 can be turned on through the power supply system of the motor 111, so that when the motor 111 rotates forward, the gear 112 drives the rack 108 to move, so that the rack 108 drives the slider 110 to slide downward in the slide groove 109, thereby making the rack 108 move downward, so that the rack 111 can be turned on. 08 slides downward through the connecting column 107, driving the bottle cap 106 and the sealing ring 105 to descend synchronously, so that the bottle cap 106 is separated from the feeding pipe 101 to open the cover, and then the beverage enters the sampling bottle 102 through the feeding pipe 101. When the motor 111 is reversed, it drives the bottle cap 106 and the sealing ring 105 to rise and close with the feeding pipe 101. After taking out the sampling device body 1, the sampling device body 1 is placed horizontally to the right, and the one-way valve 104 is opened, so that the beverage sample in the sampling bottle 102 flows out of the material pipe 103 to transport the sampling device body. The sampling device body 1 is used to sample the beverage inside the storage tank. When the device is put into the storage tank to sample the beverage, the three sampling bottles 102 and other settings enable the device to store beverages of different depths, which greatly saves the cumbersome operation of the staff and improves the labor efficiency of the staff. The sealing ring 105 is set to increase the degree of closure between the bottle cap 106 and the feed pipe 101, thereby increasing the sealing performance of the device. When in use, the staff can first fix the connecting plate 205 to the top of the storage tank, and then turn the crank 203 forward to The rotating shaft 202 embedded in the support column 204 drives the winch 201 to rotate, pays out the connecting rope 2 sleeved on its outer surface, and then drives the sampling device body 1 to descend, and then drives the sampling device body 1 to sink vertically in the storage tank through the counterweight block 113 and its own gravity to perform sampling, and through the cooperation of the connecting rope 2 and the rotating shaft 202 and other linkage structures, the device can be applied to storage tanks of different depths, which greatly increases the applicability of the device (it should be noted that the model of the motor 111 is 1LE0003, and the power is 5.5KW).
