Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to a sewage sampling detection device. Background Art

[0002] Sewage usually refers to the discharged water from life and production that is polluted to a certain extent. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants in sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. Today, environmental protection is the focus of public attention. The prevention and control of water pollution and water reuse are one of the concerns. When preventing and controlling water pollution, it is necessary to detect sewage, which requires the use of a sewage sampling and detection device to sample and detect sewage. After searching, the relevant technology (Announcement No. CN213121239U) discloses a sewage sampling and detection device, which has the effect of convenient sampling and can improve the sampling efficiency. However, during the sampling process, it is impossible to effectively filter the larger impurities in the sewage. This leads to the fact that when sampling in some sewage with more impurities and debris, it is easy to transport too many impurities and debris to the water collection tank, which not only easily causes the accumulation of impurities in the water collection tank, making it difficult to clean the water collection tank, but also easily causes pipeline blockage. Therefore, it is necessary to propose a sewage sampling and detection device. Utility Model Content

[0020] Please combine Figures 1 to 3The sewage sampling and detection device of this embodiment includes: a portable box 1 with a water collecting box 6 and a sewage detector 7 arranged inside, the portable box 1 is composed of a box shell and a box door rotatably mounted on the box shell, a handle is arranged on the top of the box shell, one side of the water collecting box 6 is a concave structure, and the remaining space is used to install a motor 11, a water suction pump 2 connected to the water collecting box 6 is arranged in the portable box 1, a connecting pipe 3 connected to the water suction pump 2 is arranged in the portable box 1, an air pump 9 is arranged on the connecting pipe 3, an extension pipe 5 is arranged at one end of the connecting pipe 3, and a winding wheel 4 for winding up the extension pipe 5 is arranged on the portable box 1;

[0021] The bobbin 13 is fixedly mounted at the end of the extension tube 5. A filter cover 16 is provided at the end of the bobbin 13. The filter cover 16 is hemispherical, which makes it less likely for impurities to adhere to it, so as to filter impurities in the sewage. A propeller 15 is provided in the bobbin 13 for driving the filter cover 16 to rotate.

[0022] A first valve 8 is installed on the connecting pipe 3 , and a second valve 10 is installed at the bottom of the water collecting tank 6 .

[0023] Through the above technical solution, the first valve 8 is used to control the connection between the connecting pipe 3 and the water suction pump 2. When the filter cover 16 needs to be aerated, the end connected to the water suction pump 2 needs to be closed to ensure normal aeration.

[0024] A motor 11 for driving the winding wheel 4 is arranged in the portable case 1. The output shaft of the motor 11 extends outside the portable case 1 and is equipped with a circular gear. The winding wheel 4 is provided with a gear ring meshing with the circular gear.

[0025] Through the above technical solution, the winding wheel 4 can be driven to rotate, thereby realizing the winding and unwinding of the extension tube 5.

[0026] The extension tube 5 consists of two parts: a soft tube and a hard tube, wherein the hard tube is L-shaped, passes through the winding wheel 4 and is fixedly connected to the winding wheel 4, the hard tube extends into the portable box 1 and is rotatably connected to the portable box 1, and one end of the hard tube is rotatably connected to one end of the connecting tube 3, so that the winding wheel 4 can rotate with the hard tube as the axis.

[0027] Through the above technical solution, it is ensured that the sewage can flow normally in the extension pipe 5, and at the same time, the winding wheel 4 can normally wind up the extension pipe 5.

[0028] A placement cylinder for storing the bobbin 13 is installed on one side of the portable box 1, and a circular hole for the filter cover 16 to pass through is provided at the bottom of the placement cylinder.

[0029] Through the above technical solution, when the extension tube 5 is rolled up, the bobbin 13 can be contained and limited, and the circular hole can avoid damage to the filter cover 16.

[0030] A shaft 14 fixedly connected to a propeller 15 and a filter cover 16 is rotatably mounted in the barrel 13 .

[0031] Through the above technical solution, the shaft 14 serves as a support for the propeller 15 and the filter cover 16, and also allows the propeller 15 to drive the filter cover 16 to rotate when driven by the water flow.

[0032] The implementation principle of a sewage sampling and detection device in the embodiment of the present application is:

[0033] The first step: when sampling, start the motor 11, and drive the winding wheel 4 to rotate through the motor 11, so as to realize the unwinding of the extension tube 5, and then put the extension tube 5 together with the bobbin 13 into the sewage;

[0034] Step 2: Start the water suction pump 2, and the sewage infiltrates the filter cover 16 through the barrel 13, the extension pipe 5 and the connecting pipe 3 to enter the water collecting box 6, so as to complete the sampling of sewage and prevent impurities from entering the water collecting box 6. It can also prevent impurities from entering the pipeline and causing pipeline blockage. When testing is required, open the second valve 10 to receive the sewage in the water collecting box 6 and then test it through the sewage detector 7;

[0035] The third step: when the sewage passes through the barrel 13, it will drive the propeller 15 to rotate, and the propeller 15 will drive the filter cover 16 to rotate through the shaft 14, so that the filter cover 16 can prevent the attachment of debris when filtering larger impurities in the sewage, so as to avoid excessive attachment of debris to the filter cover 16 to affect sampling. When impurities are attached to the filter cover 16 and are difficult to remove, close the first valve 8 and start the air pump 9, so as to reversely aerate the sewage, thereby solving the problem of filter cover 16 blockage.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
