Description

Technical Field

[0001] The utility model discloses a ceramic runoff sampling and diversion device, which belongs to the technical field of diversion devices and is applied to the fields of soil and water conservation monitoring, water quality and environmental monitoring, etc. Background Art

[0002] Water quality sampling is an important part of environmental monitoring, water resources management and scientific research. By analyzing water samples, we can evaluate the degree of water pollution, ecological health and whether it meets relevant water quality standards. Traditional sampling devices can usually only collect one sample at a time, and cannot collect multiple samples at the same time, multi-parameter analysis or multi-point sampling. During the sampling process, water samples are easily contaminated by the external environment (such as air, containers, operators), affecting the accuracy of the analysis results.

[0003] The existing Chinese utility model patent CN216746980U (announcement date: 2022.6.14) discloses a water quality detection sampling and diversion device, including a limit cover, a base and a limit tube, the bottom of the limit cover is threadedly connected to the limit tube, and the bottom of the limit tube is threadedly connected to the base; the top of the limit cover is provided with a connecting port, the outer surface of the connecting port is threadedly connected to the limit sleeve, and the top of the limit sleeve is provided with multiple water outlet pipe assemblies; the top of the limit cover is provided with a connecting seat, and the connecting seat is located on the outside of the connecting port, the top of the connecting seat is threadedly connected to a support tube, the top of the support tube is plugged with a support rod, and the top of the support rod is connected to a support clamp. However, the device still has some shortcomings. During use, water is taken in from the water inlet at the bottom, and then the water is transported to the multi-outlet water outlet pipe assembly through the pressure pump assembly. On the one hand, the collected water samples need to be transported twice to reach the multi-outlet water outlet pipe assembly, which easily causes the risk of secondary contamination of the collected water samples. On the other hand, when the water is transported to the multi-outlet water outlet pipe assembly, the water samples flow out at the same time and excessive overflow makes it difficult to collect the water samples, and it is also impossible to control the individual water outlets for directional and precise diversion of the water samples. Summary of the invention

[0004] In order to solve the technical problems such as secondary pollution caused by the diversion process of water quality after sampling and the inability to divert and accurately direct the water, the utility model proposes a ceramic runoff sampling and diversion device.

[0005] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0006] Ceramic runoff sampling and diversion device, such as Figure 1As shown, it includes a base 1 and an upper cover 2, wherein the base 1 is a cylinder with an opening at one end, and the opening end is placed upward, and the upper cover 2 is a cylinder with an opening at one end, and the opening is placed downward, and the inner diameter of the base is the same as the inner diameter of the upper cover; the open end of the upper cover 2 is covered on the base 1 and fixed together by bolts, and a water inlet 3 is provided at the upper end of the upper cover 2; Figure 2~Figure 3 As shown, a plurality of circular water outlets 4 are provided on the side wall of the base 1, and a water retaining plate 5 is provided below the circular water outlets 4 and on the inner wall of the base 1; a stepping motor 6 is provided inside the base 1 and at the center of the cylinder, and a transmission shaft 7 connected to the stepping motor 6 is located directly above the stepping motor 6, as shown in FIG. Figure 4 As shown, a circular turntable 8 is provided on the transmission shaft 7, the bottom surface of the circular turntable 8 is located above the water baffle 5, and a fan-shaped groove 9 is provided on the upper surface of the circular turntable 8. The radius of the fan-shaped groove 9 is smaller than the radius of the circular water outlet 4, and the thickness of the circular turntable 8 is the same as the diameter of the circular water outlet 4.

[0007] The beneficial effects of the utility model are as follows: the utility model proposes a ceramic runoff sampling and diversion device, the material of the diversion device is ceramic, which makes the diversion device have high hardness, strong wear resistance and strong oxidation resistance, and makes the diversion device more stable during use; the base and the cover are used to divert water samples and water samples obtained by runoff sampling, so that the diversion device is smaller in size, more flexible in operation, and easier to assemble; in the utility model, a stepper motor is provided inside the base, and cooperates with the transmission shaft and the circular turntable, and a fan-shaped groove is provided on the upper surface of the circular turntable, wherein the stepper motor is electrically connected to an external controller, and according to the demand for diversion, the controller controls the stepper motor to drive the transmission shaft and the circular turntable to rotate synchronously, so that the fan-shaped groove can be accurately docked with the circular water outlet on the base, and when one circular water outlet has collected the water sample, the stepper motor is controlled to drive the transmission shaft and the circular turntable to rotate simultaneously, so that the fan-shaped groove is aligned with the other circular water outlet, so that the water sample input from the water inlet can pass through the circular turntable The fan-shaped grooves on the disk are output to specific circular water outlets in turn, so that water samples can be accurately and directionally diverted, thereby improving the work efficiency of water sample diversion, and there are multiple circular water outlets, which can simultaneously meet the water sample diversion and collection needs of different water sample detection projects, thereby improving the accuracy of water sample detection; and compared with the prior art, the collected water samples are directly diverted, avoiding the problem of secondary pollution caused by the use of a pressure pump; in addition, the thickness of the circular turntable is the same as the diameter of the circular water outlet. When one of the circular water outlets is positioned and diverted by the fan-shaped grooves, the other circular water outlets can be blocked by the circular turntable, so that no water samples can flow out of the other circular water outlets, thereby avoiding the situation where water samples flow out at the same time and it is difficult to collect the water samples, so that the diversion device can accurately control the directional diversion of water samples; the circular turntable is located above the water baffle, and the circular turntable is close to but not close to the water baffle, so that the water baffle can prevent the water sample from dripping into the base during the transmission to the circular water outlet, thereby avoiding the waste of collected water samples.
