Description

Technical Field

[0001] The utility model relates to the field of environmental detection of water quality, and specifically relates to a water quality sampling device for environmental detection. Background Technique

[0002] Environmental detection mainly detects the quality of the environment, among which it is necessary to detect water bodies. Before detection, it is necessary to sample the water bodies, and sampling equipment is required.

[0003] Currently, the sampling equipment mainly uses a sampling bucket for sampling. After sampling with the existing sampling bucket, the water inlet hole is mainly sealed by a sealing plate. In this way, water leakage may occur after sealing, which will reduce the sampling volume of the water body and thus affect the detection result. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a water quality sampling device for environmental detection to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model proposes a water quality sampling device for environmental detection, including a sampling bucket. The bottom end of the sampling bucket is provided with a water inlet hole, and the top end of the sampling bucket is provided with a bucket cover;

[0006] A plugging mechanism is arranged inside the sampling bucket, and the plugging mechanism includes a sealing plate, a sliding rod, a baffle plate and a rubber plug. The bottom of the inner wall of the sampling bucket is fixedly installed with a sliding rod. The outer circle of the sliding rod is inserted and connected with a sealing plate. The bottom of the sealing plate is fixedly installed with a rubber plug that matches the water inlet hole. The rubber plug is used for sealing the water inlet hole, and the top end of the sliding rod is fixedly installed with a baffle plate.

[0007] In one example, a partition plate is fixedly installed on the inner wall of the sampling bucket, and an electric motor is fixedly installed on the top of the partition plate.

[0008] In one example, the output shaft of the electric motor is fixedly installed with a rotating shaft, and the rotating shaft penetrates and extends outside the partition plate.

[0009] In one example, a limiting plate is fixedly installed at the bottom end of the rotating shaft, and the limiting plate is connected to the sealing plate.

[0010] In one example, two fixed shafts are fixedly installed on the outer circle of the sampling bucket, and arc-shaped handles are rotatably connected to the mutually remote ends of the two fixed shafts.

[0011] In one example, a water outlet pipe is fixedly installed at the bottom of the outer circle of the sampling bucket, and a control valve is rotatably connected to the outer circle of the water outlet pipe.

[0012] An environmental detection water quality sampling device proposed by the present utility model can bring the following beneficial effects:

[0013] 1. For the environmental detection water quality sampling device, through the cooperation of structures such as the plugging mechanism, electric motor, rotating shaft and limiting plate, when the limiting plate is separated from the sealing plate, at this time, under the action of water pressure, the rubber plug will be pushed upward, and the sealing plate will move upward along the sliding rod. When the water inlet hole is exposed, water will enter. When the sampling bucket with the baffle is lifted upward, at this time, under the action of the gravity of water, the sealing plate will be pressed downward, and the water inlet hole will be plugged by the rubber plug to avoid leakage after sampling.

[0020] In order to more clearly explain the overall concept of the present utility model, the following is a detailed description by way of example in conjunction with the drawings of the specification.

[0021] As Figures 1 to 4 shown, an embodiment of the present utility model proposes an environmental detection water quality sampling device, including a sampling bucket 1. A water inlet hole 12 is opened at the bottom end of the sampling bucket 1, and a bucket cover 2 is provided at the top end of the sampling bucket 1;

[0022] Inside the sampling bucket 1, there is a plugging mechanism, and the plugging mechanism includes a sealing plate 9, a sliding rod 10, a baffle 11 and a rubber plug 13. At the bottom of the inner wall of the sampling bucket 1, a sliding rod 10 is fixedly installed. The outer circle of the sliding rod 10 is inserted with a sealing plate 9. At the bottom of the sealing plate 9, a rubber plug 13 matching the water inlet hole 12 is fixedly installed. The rubber plug 13 is used to seal the water inlet hole 12. At the top of the sliding rod 10, a baffle 11 is fixedly installed.

[0023] Specifically, a partition plate 5 is fixedly installed on the inner wall of the sampling bucket 1. At the top of the partition plate 5, an electric motor 6 is fixedly installed. The electric motor 6 is fixed by the partition plate 5, and the electric motor 6 drives the rotating shaft 7 to rotate.

[0024] Specifically, the output shaft of the electric motor 6 is fixedly installed with a rotating shaft 7, and the rotating shaft 7 penetrates and extends outside the partition plate 5. By rotating the rotating shaft 7, the limiting plate 8 is driven to rotate, and the sealing plate 9 is pressed tightly to seal the water inlet hole 12.

[0025] Specifically, the bottom end of the rotating shaft 7 is fixedly installed with a limiting plate 8. The limiting plate 8 is connected to the sealing plate 9. The rubber plug 13 is fixed by the sealing plate 9 to seal the water inlet hole 12.

[0026] Specifically, two fixed shafts 3 are fixedly installed on the outer circle of the sampling bucket 1. At the far ends of the two fixed shafts 3 away from each other, arc-shaped handles 4 are rotatably connected. The arc-shaped handles 4 are fixed by the fixed shafts 3, and the arc-shaped handles 4 are convenient for lifting the sampling bucket 1.

[0027] Specifically, a water outlet pipe 14 is fixedly installed at the bottom of the outer circle of the sampling bucket 1. The outer circle of the water outlet pipe 14 is rotatably connected with a control valve 15. The water in the sampling bucket 1 is discharged through the water outlet pipe 14, and the control valve 15 controls the water outlet pipe 14.

[0028] Working principle: Put the sampling bucket 1 into the water area where sampling is required. At this time, start the electric motor 6 to drive the rotating shaft 7 to rotate, and drive the limiting plate 8 to rotate. When the limiting plate 8 is separated from the sealing plate 9, at this time, under the action of water pressure, the rubber plug 13 will be separated from the water inlet hole 12, and the sealing plate 9 will move upward along the sliding rod 10, exposing the water inlet hole 12, so as to achieve the effect of water sampling. After sampling, pull out the sampling bucket 1 through the arc-shaped handle 4. At this time, under the action of the gravity of the water, the sealing plate 9 moves downward, and the rubber plug 13 seals the water inlet hole 12, avoiding the leakage phenomenon after water sampling, and achieving the sampling effect. After sampling, rotate the control valve 15 to sample the water through the water outlet pipe 14, and then detect it.

[0029] Each embodiment in this specification is described in a progressive manner.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and for the relevant parts, reference can be made to the description in the method embodiment.

For those skilled in the art, various modifications and changes can be made to the present invention.
