Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, specifically relating to a sampling device for sewage discharge into the sea. Background Technology

[0002] To reduce environmental pollution, wastewater needs to be purified before discharge. To ensure the effectiveness of purification, the discharged wastewater also needs to be sampled and tested. Currently, most common sampling and testing methods involve extracting wastewater from the discharge pipe using an extraction device, storing it, and then testing it. However, this method can only perform a single test. As the discharge continues, continuous sampling and testing are often required, which presents an inconvenience in the sampling and testing process. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater discharge sampling device for the sea, which addresses the problems mentioned in the background art.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows: A wastewater discharge sampling device for the sea includes a discharge pipe, a bypass pipe provided on the side of the discharge pipe, and a sampling mechanism connected to the bypass pipe; The sampling mechanism consists of a connecting pipe, a driver, a connecting plate, and several sampling bottles. The connecting pipe is sealed to a bypass pipe via a flange. The driver is located on the side of the connecting pipe. The connecting plate is concentrically connected to the driver and covers the outlet of the connecting pipe. The connecting plate is rotatably sealed to the outlet of the connecting pipe. Several sampling bottles are evenly arranged on the underside of the connecting plate.

[0005] The sewage pipe is equipped with a filter bag that matches the position of the bypass pipe.

[0006] The connecting pipe has a built-in water pump.

[0007] The driver consists of a motor and a top cover. The motor is fixedly connected to the side of the connecting pipe via a bracket. The top cover is rotatably and sealed to the upper end of the connecting plate and is fixedly connected to the connecting pipe. The output shaft of the motor rotates through the top cover and is connected to the connecting plate via a transmission connection.

[0008] The sampling bottle consists of a bottle body and a one-way valve plug, with the one-way valve plug embedded at the liquid inlet of the bottle body.

[0009] This application has at least the following advantages compared to the prior art: This application, through the setup of a driver, connecting plate, and sampling bottle, enables wastewater discharge sampling at different times, without the need for manual replacement of sampling bottles or the installation of multiple sampling devices, thus achieving convenient and rapid sampling and testing.

[0015] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-3 As shown, a wastewater discharge sampling device for the sea includes a discharge pipe 1, a bypass pipe 11 is provided on the side of the discharge pipe 1, and a sampling mechanism is connected to the bypass pipe 11. The sampling mechanism consists of a connecting pipe 2, a driver, a connecting plate 21, and several sampling bottles. The connecting pipe 2 is sealed to the bypass pipe 11 through a flange. The driver is located on the side of the connecting pipe 2. The connecting plate 21 is concentrically connected to the driver and covers the outlet of the connecting pipe 2. The connecting plate 21 is rotatably sealed to the outlet of the connecting pipe 2. Several sampling bottles are evenly arranged on the lower side of the connecting plate 21.

[0017] In the silent state, the drain pipe 1 is used to discharge the purified sewage, while the bypass pipe 11 is used in conjunction with the sampling mechanism to sample the sewage in the drain pipe 1. During sampling, the connecting pipe 2 is opened so that the water in the drain pipe 1 passes through the connecting plate 21 and enters the sampling bottle. The opening of the sampling bottle passes through the connecting plate 21, and the entire sampling bottle and the connecting plate 21 can be connected by any convenient connection method such as threaded sealing or snap-fit, which facilitates the replacement of the sampling bottle later. As sewage discharge proceeds, in order to ensure the effectiveness of purification, it is necessary to sample and inspect the sewage regularly. The driver itself has a timed start-stop function through a clockwork clock or microcontroller, which can intermittently start and stop, thereby driving the connecting plate 21 to rotate and switch the sampling bottle of the corresponding connecting tube 2. This can achieve the effect of changing the sampling container. Compared with manual timed sampling or sampling with a single sampling device, it can reduce manual intervention and improve the convenience of sampling and testing.

[0018] The drain pipe 1 is equipped with a filter bag 3 that matches the position of the bypass pipe 11.

[0019] The filter screen 3 can prevent some impurities from entering the bypass pipe 11 and clogging or affecting the corresponding devices.

[0020] The connecting pipe 2 has a built-in water pump 4.

[0021] The water pump 4 is used to provide the extraction power during sampling. Of course, in some embodiments, the water pump 4 built into the connecting pipe 2 can also be a water valve, so as to achieve the effect of directly inputting the water sample into the sampling bottle.

[0022] The driver consists of a motor 5 and an upper cover 51. The motor 5 is fixedly connected to the side of the connecting pipe 2 via a bracket. The upper cover 51 is rotatably and sealed to the upper end of the connecting plate 21 and is fixedly connected to the connecting pipe 2. The output shaft of the motor 5 rotates through the upper cover 51 and is connected to the connecting plate 21 for transmission.

[0023] The top cover 51 is used to close and protect the sampling bottle opening exposed at the top of the connecting plate 21 to prevent contamination by external impurities.

[0024] The sampling bottle consists of a bottle body 6 and a one-way valve plug 61, with the one-way valve plug 61 embedded at the liquid inlet of the bottle body 6.

[0025] Bottle 6 is used to store samples. One-way valve plug 61 is connected to bottle 6 by plugging and unplugging to facilitate the pouring out of liquid during subsequent testing. One-way valve plug 61 can also have a diaphragm hole. The diaphragm hole corresponds to the opening direction of bottle 6 and is made of rubber diaphragm. The rubber diaphragm has a cross opening in the middle. In the silent state, the rubber diaphragm is kept closed by its own elasticity. When water pressure is applied, water passes through the diaphragm hole and enters bottle 6. The air in bottle 6 is simultaneously output to connecting tube 2. During the removal of bottle 6, due to the presence of atmospheric pressure, the slow movement will not cause the sample liquid in bottle 6 to overflow. Finally, it can be carried by sealing it with the bottle cap.

[0026] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
