Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to an online total nitrogen monitoring device in water quality environment monitoring using a spectrometer method. Background Art

[0002] In water quality environmental monitoring, the determination of total nitrogen is an important link; currently, the commonly used total nitrogen detection methods mainly include ultraviolet spectrophotometry and gas phase molecular absorption spectroscopy. Ultraviolet spectrophotometry is usually used for water quality monitoring of rivers, lakes, etc., and the total nitrogen concentration in the water sample is determined by measuring the absorbance.

[0003] The reference patent name is: An online automatic monitoring device with a water quality total nitrogen analyzer (patent authorization announcement number: CN212031445U, patent announcement date: 2020-11-27). When in use, it floats on the river through a polyurea float. The total nitrogen analyzer is powered by solar panels and its built-in sampling water pump draws river water through a sampling tube and sends it to the total nitrogen analyzer for water quality analysis. The water quality analysis data is transmitted to the remote network server by the embedded industrial computer system of the total nitrogen analyzer through CDMA, GPRS or 4G network, and then the monitoring data is received by the monitoring terminal connected to the remote network server for real-time monitoring; when the online automatic monitoring device is pulled out of the water and needs to be moved to other rivers for use or to a maintenance center for maintenance, the adjustment frame pulls out the insertion tube, the wheel frame is adjusted to be perpendicular to the adjustment frame, and the entire online automatic monitoring device is turned over so that the universal casters are on the ground, and the adjustment frame and the wheel frame constitute a cart structure, which can be easily moved by pulling the handle.

When the overall device in the above scheme is moved, the device needs to be flipped over first. At this time, the internal related detection and networking structure and the solar panel structure are difficult to ensure their position stability after long-term use, and it is difficult to avoid bumps during the movement. If the internal components are damaged during the movement, it will affect the subsequent use of the device. For this reason, the utility model provides an online monitoring device for total nitrogen in water quality environment monitoring using a spectrometer method. Utility Model Content

A slidable folding frame 42 is set inside the support frame 41, and a blocking block 44 is used to enable the moving wheel 43 to rotate when the folding frame 42 slides, so that the moving wheel 43 is prompted to expose the floating plate 2 after the folding frame 42 moves outward, and the moving wheel 43 will shrink after the folding frame 42 moves into the support frame 41, so that the moving wheel 43 and the folding frame 42 that assist in the movement can be achieved on the basis of the overall structure of the floating plate 2 remaining unchanged, thereby ensuring that the basic components will not be reversed during movement.

[0030] Embodiment 2

[0031] The main difference from the first embodiment is:

[0032] The total nitrogen online monitoring device in the water quality environment monitoring by spectrometer method, the fixed component 5 includes a fixed rod 51 and an operating rod 52 that slide inside the folding frame 42, a fixed groove 53 is provided inside the support frame 41, a fixed spring 54 is fixedly connected between the fixed rods 51, a fixed belt 55 is fixedly connected to the surface of the fixed rod 51, a fixed ring 56 is provided for internal rotation of the folding frame 42, the surface of the operating rod 52 is slidably connected to the inside of the fixed ring 56, a spring is fixedly connected between the operating rod 52 and the folding frame 42, the driving component 6 includes a driving groove 61 provided on the surface of the blocking block 44, a driving tooth 62 is fixedly connected inside the driving groove 61, the driving tooth 62 is unevenly fixed inside the driving groove 61, a driving column 63 is fixedly connected inside the moving wheel 43, one end of the driving column 63 is fixedly connected to a driving gear 64, and the surface of the driving gear 64 is aligned with the surface of the driving tooth 62 The surface of the driving column 63 is connected to the internal rotation of the floating plate 2, and the sealing assembly 7 includes a sealing block 71 that slides with the inside of the shielding block 44. The surfaces of the shielding block 44 and the floating plate 2 are provided with sealing grooves 72. The sealing grooves 72 have two shapes. The grooves on the surface of the shielding block 44 are arc-shaped, and the grooves on the surface of the floating plate 2 are rectangular grooves. Sliding sealing blocks 71 are set through grooves of different shapes on the bottom surfaces of the floating plate 2 and the shielding block 44, so that the sealing block 71 can be controlled to slide in a straight line under the action of the rotation of the shielding block 44, and then it can slide to the position of the moving wheel 43 after the moving wheel 43 is folded to form a shielding there. Then, when the entire device is suspended on the water surface, it can effectively isolate the moving wheel 43 from water, avoid rusting and other wear of the moving wheel 43, and ensure the effective use time of the device. The sliding limit between the folding frame 42 and the supporting frame 41 can be achieved by simple pressing, which is easy to operate.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] During operation, when it is necessary to move the floating plate 2, first press the operating rod 52. The pressing of the operating rod 52 can drive the fixing ring 56 to rotate, and then the fixing ring 56 drives the fixing belt 55 to wrap around to shrink the fixing belt 55, so that the fixing rod 51 is brought closer, and then the surface of the fixing rod 51 is separated from the inner surface of the fixing groove 53, and the folding frame 42 is pulled. The sliding of the folding frame 42 can drive the transfer groove 46 to slide, and then the blocking block 44 is rotated through the transfer column 45. The rotation of the blocking block 44 drives the moving wheel 43 to rotate by driving the teeth 62 and the driving gear 64, and the sealing block 71 can be driven to slide toward the center position during the rotation of the blocking block 44. At this time, the moving wheel 43 will be perpendicular to the floating plate 2. When the folding frame 42 moves to the appropriate position, release the operating rod 52. The operating rod 52 will return to its position under the action of the spring. At this time, the folding frame 42 can be pulled, and the entire device can be moved by moving the wheel 43 and pulling the folding frame 42.
