[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figure 1-Figure 3 As shown, a water quality detection device convenient for sampling includes a water quality detection device body 1. The storage groove opened by the hinged movable frame 2 of the water quality detection device body 1 is used as the placement place of the fixed frame 3. When the fixed frame 3 is not in use, the movable plate 6 is pulled to drive the rubber sheet 7, the connecting pipe 8 and the rubber sleeve 9, and the movable plate 6 rotates on the hinged fixed frame 3. The top of the movable plate 6 abuts against the top of the fixed frame 3, and then the connecting bolt 11 is screwed and connected with the threaded hole opened on one side of the top of the fixed frame 3 to fix the position of the movable plate 6 on the fixed frame 3 at this time, and then the fixed frame 3 is pulled to drive the fixed sleeve 4, the sampling assembly 5 and the movable plate 6, and the fixed frame 3 is placed horizontally and stored in the storage groove opened by the movable frame 2 to complete the storage of the fixed frame 3, reduce the floor area of ​​the fixed frame 3, save storage space, and facilitate the staff to carry it.

[0030] When it is necessary to use the water quality detection device body 1 for water sample detection, pull the fixed frame 3 out of the storage groove opened by the movable frame 2, place the bottom of the fixed frame 3 on the bottom of the inner wall of the storage groove opened by the movable frame 2, and then loosen the connecting bolts 11 to detach from the fixed frame 3, pull the movable plate 6 to drive the rubber sheet 7, the connecting tube 8 and the rubber sleeve 9 to unfold on the fixed frame 3, and then put the opening of the water sample bottle 10 on the outside of the rubber sleeve 9, use the friction between the rubber sleeve 9 and the opening of the water sample bottle 10 to fix the water sample bottle 10 on the connecting tube 8, and then pull the water sample bottle 10. The sample bottle 10 drives the rubber sleeve 9 to drive the connecting tube 8 to drive the movable plate 6 to rotate on the fixed frame 3, and the movable plate 6 is placed on the fixed frame 3 again. The rubber sheet 7 now serves as a plug at the opening of the connecting tube 8 and the water sample bottle 10 to prevent the water sample in the water sample bottle 10 from flowing out. The water sample bottle 10 drives the movable plate 6 to rotate 180 degrees on the fixed frame 3. The water sample bottle 10 is inverted on the fixed frame 3. The water sample in the water sample bottle 10 naturally flows down under the action of gravity. The low water sample level does not affect sampling. Compared with traditional water sampling, it is more convenient and convenient for subsequent water sampling.

[0031] like Figure 3-Figure 6 As shown, when the water sample bottle 10 is hung upside down on the fixing frame 3, the rubber sheet 7 blocking the water sample bottle 10 passes through the top of the three-way pipe 503, and the top of the three-way pipe 503 enters the opening of the water sample bottle 10. At this time, the adjusting screw 512 on the upper side of the three-way pipe 503 is turned, and the three-way pipe 503 and the installation pipe 502 are connected. The water sample in the water sample bottle 10 passes through the three-way pipe 503 and enters the connected installation pipe 502 and then enters the measuring cylinder 501, and the driving motor 508 is started, and the output of the driving motor 508 is turned on. The end drives the movable sleeve 507 to rotate under the fixation of the top screw 509, and the movable sleeve 507 drives the connecting screw rod 506 through the thread to drive the movable block 505 to slide downward in the measuring cylinder 501. The movable block 505 cooperates with the sealing ring 510 to extract the water sample in the water sample bottle 10 through the mounting tube 502 and the three-way tube 503, and observes that the water level in the measuring cylinder 501 reaches the scale. Extract water according to demand, which makes water sampling more convenient and convenient for detection personnel to use. The extraction amount is also more accurate, which improves the accuracy of subsequent detection.

[0032] like Figure 4-Figure 6 As shown, after the water sample is quantitatively extracted into the measuring cylinder 501, the driving motor 508 is stopped, and the test personnel places the test tube on the elastic silicone pad 12 in the fixed sleeve 4, compresses the elastic silicone pad 12 with the test tube, and then aligns the opening of the test tube with the bottom opening of the three-way tube 503, so that the test tube is connected to the bottom opening of the three-way tube 503, and then the adjusting screw 512 on the upper side of the three-way tube 503 is turned to close the connection between the water sample bottle 10 and the installation tube 502, and then the three-way tube 503 is unscrewed. 03, the adjusting screw rod 512 below, the installation tube 502 is connected with the test tube through the three-way tube 503, the driving motor 508 is started to reverse and drive the movable sleeve 507 to reverse, the movable sleeve 507 drives the connecting screw rod 506 through the thread to drive the movable block 505 to cooperate with the sealing ring 510 to push the water sample in the measuring cylinder 501, and the water sample in the measuring cylinder 501 is pushed into the test tube to complete the test tube sampling. The sampling process does not require the test personnel to hold the test tube for operation, which is convenient for the test personnel to use and makes sampling more convenient.

[0033] After the sampling and testing is completed, the mounting bolt 504 is turned to disengage the measuring cylinder 501, the top screw 509 is turned to disengage the output end of the driving motor 508, the movable sleeve 507 is pushed to drive the connecting screw 506 to drive the movable block 505 to enter the measuring cylinder 501, one end of the movable sleeve 507 is disengaged from the output end of the driving motor 508, the measuring cylinder 501 is pulled to drive the mounting tube 502 to disengage one end of the three-way tube 503, so that the measuring cylinder 501 is removed from the fixed frame 3, and then the inside of the measuring cylinder 501 is cleaned to prevent residual water sample in the measuring cylinder 501 and contamination of subsequent water sample samples, so as to facilitate subsequent sampling.
