Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring devices, in particular to a monitoring device for ammonia nitrogen and sub-salt in water. Background Art

[0002] Water is an important medium for the circulation of various elements in the natural environment. Pollutants generated by human production and life are usually discharged into the natural environment in the form of aqueous solutions, which changes the chemical composition and water quality of water in the natural environment, thereby affecting water for industrial and agricultural production and human life. At the current stage, the pollution of surface water in my country is still quite serious. Ammonia nitrogen is widely present in surface water and groundwater. Ammonia nitrogen (NH3-N) exists in water bodies in the form of free ammonia (NH3) or ammonium salts (NH4+). Ammonia nitrogen is an important factor in eutrophication in water bodies. When the ammonia nitrogen content in water is high, the water body is black and accompanied by a foul odor, which is poisonous to aquatic plants and even causes the death of aquatic organisms such as fish and shrimp. In addition, ammonia nitrogen can be decomposed into nitrite under the action of microorganisms. When the nitrite content in water exceeds the standard, drinking this water will cause nitrite to combine with protein in the human body to form a strong carcinogen-nitrosamine. Long-term drinking of water with excessive ammonia nitrogen is also extremely harmful to the body. Therefore, the ammonia nitrogen content is an important indicator for evaluating the quality of the water environment.

[0003] With regard to the existing related technologies, the inventors believe that the following defects exist: when sampling water quality, water pumps are mostly used to extract water for sampling, so that sand, debris or other solid debris may exist in the extracted water, which in turn causes the solid debris in the water to affect the water quality detection.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example 1: Please refer to Figure 1 - Figure 4 The present embodiment is a monitoring device for ammonia nitrogen and nitrite in water quality, comprising a detection device body 1, a collection chamber 2 is processed inside the detection device body 1, a separation channel 3 is processed on one side of the collection chamber 2, a detection chamber 4 is processed on the bottom of the separation channel 3, a discharge channel 5 is processed on the bottom of the collection chamber 2, a baffle 6 is hingedly connected to one side of the collection chamber 2, the discharge channel 5 is hingedly connected to the bottom of the collection chamber 2, a fixing plate 8 is fixedly connected to the inner wall of the top of the separation channel 3, a hydraulic rod 9 is fixedly connected to one side of the fixing plate 8, and one end of the hydraulic rod 9 is hingedly connected to the inner side of the baffle 6;

[0023] The water in the detection area is pumped into the collection chamber 2 through a water pump, so that the water quality to be detected is precipitated in the collection chamber 2. After the precipitation is completed, the hydraulic rod 9 is started, and the hydraulic rod 9 will drive the bottom of the baffle 6 to move, so that the top of the baffle 6 rotates upward around the top inner wall of the separation channel 3, and the separation channel 3 is opened, so that the collection chamber 2 is connected with the separation channel 3, so that the water in the collection chamber 2 passes through the separation channel 3 to reach the detection chamber 4. The water quality will be tested in the detection chamber 4, and will be discharged through the drain port at the bottom of the detection chamber 4 after the test is completed;

[0024] Secondly, since the connection between the separation channel 3 and the collection chamber 2 is higher than the bottom of the collection chamber 2, the sand and debris in the water can be deposited at the bottom of the collection chamber 2 and located on the top of the flap 7, so that when the baffle 6 is opened, the middle and upper layers of water in the collection chamber 2 enter the separation channel 3, preventing the sand, debris and other impurities at the bottom of the collection chamber 2 from entering the detection chamber 4 through the separation channel 3;

[0025] Further, a placement groove 10 is processed on the inner wall of one side of the collection chamber 2, and a gear 16 is rotatably connected inside the placement groove 10, and a first rack 18 is meshingly connected to the bottom of the gear 16, and a first slide bar 12 is fixedly connected to one end of the first rack 18, and the first slide bar 12 is located on the outside of the baffle 6, and a second rack 20 is meshingly connected to one side of the gear 16, and a second slide bar 14 is fixedly connected to the bottom of the second rack 20, and the second slide bar 14 is located on the top of the flap 7;

[0026] When the baffle 6 is opened, the water in the collection chamber 2 passes through the separation channel 3 to reach the inside of the detection chamber 4, and the hydraulic rod 9 will continue to push the bottom of the baffle 6 to rotate upward. When the baffle 6 rotates upward, it will push the first slide bar 12 to move, and the movement of the first slide bar 12 will drive the first rack 18 to move, and the movement of the first rack 18 will drive the gear 16 to rotate, and the rotation of the gear 16 will drive the second rack 20 to move downward, and the downward movement of the second rack 20 will drive the second slide bar 14 to move downward;

[0029] Furthermore, a first slide groove 11 is processed on the inner wall of one side of the collection chamber 2, and a first slide rod 12 is movably connected inside the first slide groove 11.

[0031] Furthermore, the placement groove 10 is fixedly connected to the inside of the first fixing groove 17, and the first rack 18 is movably connected to the inside of the first fixing groove 17. By providing the first fixing groove 17, the first rack 18 will move along the inside of the first fixing groove 17, so that the first fixing groove 17 limits the first rack 18, so that the first rack 18 remains in a stable state when moving;

[0032] Furthermore, the interior of the placement groove 10 is fixedly connected to a second fixed groove 19, and the second rack 20 is movably connected to the interior of the second fixed groove 19. By providing the second fixed groove 19, the second rack 20 will move along the interior of the second fixed groove 19, so that the second fixed groove 19 limits the second rack 20, so that the second rack 20 remains in a stable state when it moves.

[0033] Working principle: by pumping water into the collection chamber 2 for internal sedimentation, and then starting the hydraulic rod 9, the hydraulic rod 9 will drive the top of the baffle 6 to rotate upward, open the separation channel 3, and connect the collection chamber 2 with the separation channel 3, so that the water inside the collection chamber 2 passes through the separation channel 3 to the inside of the detection chamber 4, so that the water quality will be detected inside the detection chamber 4, and the hydraulic rod 9 will continue to push the bottom of the baffle 6 to rotate upward, the baffle 6 will push the first slide bar 12 to move, the first slide bar 12 will drive the first rack 18 to move, the first rack 18 will drive the gear 16 to rotate, the gear 16 will drive the second rack 20 to move downward, the downward movement of the second rack 20 will drive the second slide bar 14 to move downward, so that the second slide bar 14 pushes one end of the flap 7 to rotate, and then opens the excretion channel 5, so that the water with impurities such as sand, gravel, and debris at the bottom of the collection chamber 2 is discharged, which is convenient for collecting and sampling inside the collection chamber 2 again.
