DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, the utility model provides a rapid sampling device for laboratory sewage treatment, including a sampling tube 1, a long rod 2 is fixedly connected to the top of the sampling tube 1, a groove 3 is opened on the right side of the surface of the sampling tube 1, and the number of the grooves 3 is three. A water inlet mechanism 4 is arranged inside the sampling tube 1, and a sampling mechanism 5 is arranged on the left side of the sampling tube 1.

[0022] refer to Figure 3 The water inlet mechanism 4 includes a round block 41, which is movably connected to the inner side of the groove 3. A spring 42 is fixedly connected to the left side of the round block 41, a fixing frame 43 is fixedly connected to the side of the spring 42 away from the round block 41, and a side of the fixing frame 43 close to the round block 41 is fixedly connected to the groove 3.

[0023] As a technical optimization scheme of the utility model, by setting up the water inlet mechanism 4, when sampling sewage, the sampling tube 1 is placed in the sewage, and the sewage squeezes the round block 41, the round block 41 moves into the inside of the tube, and the sewage groove 3 enters the interior of the sampling tube 1, and then the sampling tube 1 is lifted upward by the long rod 2. When the sampling tube 1 is lifted, the spring 42 rebounds and drives the round block 41 to block the groove 3 so that the sewage will not flow out, thereby improving the efficiency of sewage sampling.

[0024] refer to Figure 4 The sampling mechanism 5 includes a flow tube 51, which is connected to the surface of the sampling tube 1. There are three flow tubes 51, and the three flow tubes 51 are equidistantly distributed. A flow tube 52 is provided inside the flow tube 51. A circular plate 53 is fixedly connected to the side of the flow tube 52 away from the flow tube 1 51. The front and rear sides of the circular plate 53 are fixedly connected to handles 54. A spring 2 55 is fixedly connected to the side of the handle 54 close to the sampling tube 1. A small sampling bottle 56 is threadedly connected to the bottom of the flow tube 52.

[0025] As a technical optimization scheme of the utility model, by setting up the sampling mechanism 5, when sampling, the handle 54 can be pushed to move to one side of the sampling tube 1. The movement of the handle 54 drives the flow tube 2 52 to move to one side of the flow tube 1 51. The flow tube 1 51 and the flow tube 2 52 are combined so that the sewage flows into the small sampling bottle 56 through the internal opening for collection. The spring 2 55 rebounds and drives the flow tube 2 52 to move outward so that the opening is misplaced and the sewage no longer flows out. The sewage sample is taken out by loosening the small sampling bottle 56, thereby improving the effect of sewage sampling.

[0026] refer to Figure 1 The top of the circular plate 53 is movably connected to a baffle 6 , and the right side of the baffle 6 is fixedly connected to the surface of the sampling tube 1 .

[0027] As a technical optimization solution of the utility model, by setting a baffle 6, the circular plate 53 driven by the spring 2 55 when it rebounds can be limited, avoiding excessive elastic force during rebound that causes the flow tube 2 52 and the flow tube 1 51 to fall off, thereby improving the service life of the flow tube 2 52.

[0028] refer to Figure 1 A counterweight block 7 is fixedly connected to the bottom of the sampling tube 1 , and the counterweight block 7 is located at the bottom of the small sampling bottle 56 .

[0029] As a technical optimization solution of the utility model, by providing the counterweight block 7, when the sampling tube 1 is placed in sewage, it can prevent deviation and error in sewage sampling, thereby improving the use effect of the sampling tube 1.

[0030] refer to Figure 1A scale rod 8 is fixedly connected to the front side of the sampling tube 1 , and the scale rod 8 is located on the top of the counterweight block 7 .

[0031] As a technical optimization solution of the utility model, by setting a scale rod 8, it can be used in conjunction with the observation window 9. When sewage sampling does not require too many samples, it can be observed through the scale rod 8. When the sewage inflow reaches the requirement, the sampling tube 1 is lifted, thereby improving the use efficiency of the sampling tube 1.

[0032] refer to Figure 1 An observation window 9 is provided on the top of the sampling tube 1 , and the observation window 9 is located on the right side of the long rod 2 .

[0033] As a technical optimization solution of the utility model, by setting an observation window 9, it can be used in conjunction with the scale rod 8, and the sampling amount of sewage inside the sampling tube 1 can be observed through the observation window 9, thereby improving the use effect of the scale rod 8.

[0034] The working principle and use process of the utility model are as follows: when using, the sewage is sampled by placing the sampling tube 1 in the sewage, and the sewage squeezes the round block 41, and the round block 41 moves toward the inside of the sampling tube 1, and the sewage enters the inside of the sampling tube 1 along the groove 3. When the sampling tube 1 is filled with sewage, the sampling tube 1 is lifted up by the long rod 2. When the sampling tube 1 is lifted, the spring 1 42 rebounds and drives the round block 41 to move toward one side of the groove 3, and the groove 3 is blocked by the round block 41, so that the sewage does not flow out. When sampling, the handle 54 is pushed to move toward one side of the sampling tube 1, and the movement of the handle 54 drives the flow tube 2 52 to move toward one side of the flow tube 1 51. When the circulation tube 1 51 and the circulation tube 2 52 are combined, they are connected. Through the internal opening, the sewage flows along the circulation tube 2 52 through the circulation tube 1 51 into the small sampling bottle 56 for collection. The spring 2 55 rebounds and drives the circulation tube 2 52 to move outward to dislocate the opening. The sewage inside the sampling tube 1 no longer flows out. The small sampling bottle 56 is then removed by rotation to take out the sewage sample. This has the advantage of convenient sampling and solves the problem of sampling and analyzing the upper, middle and bottom layers of the sewage through three groups of small sampling bottles 56 when sampling the sewage. There is no need for the inspectors to perform multiple samplings, which reduces the sampling time of the inspectors and improves the inspection efficiency of the inspectors.

[0035] To sum up: the rapid sampling device for laboratory sewage treatment, through the coordinated use of the sampling tube 1, the long rod 2, the groove 3, the water inlet mechanism 4 and the sampling mechanism 5, solves the problem that when sampling sewage, sampling is carried out through three sample storage spaces. Because the partitions of the three sample storage spaces will cause the samples obtained during sampling to be the same, it is impossible to perform upper, middle and lower stratified detection of water samples, and the test personnel need to take multiple samples to measure the average value, which increases the sampling time of the test personnel and reduces the test efficiency of the test personnel.
