[0031] The circumferential surface of the shell 101 is provided with a plurality of exhaust ports 110, which are aligned with the auxiliary cooling fins 112. The outer surface of the shell 101 is also fixedly installed with a top cover 105 through a support plate 106, so as to form an air inlet gap between the shell 101 and the top cover 105. The top cover 105 is fixedly installed with a cooling motor 108, and the output shaft of the cooling motor 108 is fixedly matched with a cooling fan blade 109. The axial position of the shell 101 is also provided with an air inlet 107, which is coaxially aligned with the cooling fan blade 109. The bottom end of the shell 101 is fixedly installed with a liquid leakage tank 103, and the axial position of the liquid leakage tank 103 is fixedly installed with a water inlet pipe 104. The contact position of the water inlet pipe 104 and the liquid leakage tank 103 is provided with a drain groove. A retaining shielding ring 116 is fixedly installed on the inner wall of the water inlet pipe 104. A retaining guide rod support 119 is fixedly installed on the inner side of the retaining shielding ring 116. A retaining guide rod 120 is slidingly installed at the axial position of the retaining guide rod support 119.

[0032] The shell 101, the drain pipe 128 and the rectangular transparent detection channel 129 in the figure are not in actual proportion length, but in shortened proportion length for the convenience of description. In use, the ultraviolet light emitting unit 121 is started, and the light emitted by the ultraviolet light emitting unit 121 (for example, ultraviolet light with a wavelength of 254 nm; or the ultraviolet light emitting unit 121 is composed of multiple ultraviolet light sources with different wavelengths, each light source corresponds to a focusing lens 124, and a light shield is arranged between each light source and the focusing lens 124 to prevent mutual interference, so that multiple ultraviolet lights with different wavelengths can be obtained; some substances can absorb light of a specific color; examples: organic matter likes to absorb ultraviolet light with a wavelength of 254 nm; nitrate is sensitive to 220 nm; used to increase the detection range) can irradiate through the focusing lens 124, the focusing lens 124 focuses the light onto the collimating lens 126, the collimating lens 126 collimates the light into a parallel light beam, and then irradiates along the axial direction of the shell 101 to the inner side mirror 132, the inner side mirror 132 reflects the light to the outer side mirror 133, and then the outer side mirror 133 reflects the light to the image sensor 115, which is received by the image sensor 115. The image sensor 115 is used to detect the change of light.

[0033] The cap 102 is separated from the shell 101, and then the water inlet pipe 104 is inserted into the saline water to be detected. The axial flux motor 136 is started, and the output shaft of the axial flux motor 136 drives the driving main shaft 147 to rotate, and the driving main shaft 147 drives the centrifugal drainage impeller 146 and the water suction impeller 145 to rotate. The water suction impeller 145 draws the inside of the water suction pipe 144 and the water inlet pipe 104 into negative pressure, so that the saline water enters. At this time, the saline water pushes away the sealing retention plate 118 (the sealing retention plate 118 is separated from the shielding retention ring 116, so that a gap is formed between the two, for the saline water to flow through, which needs to overcome the elastic force of the retention spring 117, so that the retention spring 117 is compressed; for the saline water to stay in the rectangular transparent detection channel 129 when not working, and to be discharged by re-starting or sucking clean water) under the action of pressure difference, and is sucked into the inside of the water suction pipe 144. The saline water sucked into the water suction pipe 144 also enters the space between the second sealing cover plate 143 and the first sealing cover plate 135, and is then driven to rotate by the rotating centrifugal drainage impeller 146, so that the rotating saline water is subjected to centrifugal force to flow into the bottom annular cavity 130, and then flows into the top annular cavity 127 along the rectangular transparent detection channel 129 under the push of pressure, and then flows out from the bottom annular cavity 130 below along the drainage pipe 128, that is, flows into the leakage bucket 103, and then flows out from the drainage groove of the leakage bucket 103. At this time, the rectangular transparent detection channel 129 is filled with saline water, which will shield the ultraviolet light beam emitted by the ultraviolet light emitting unit 121 (the shielding state of the light beam is detected by the image sensor 115), specifically: absorption (darkening): some substances will absorb light of a certain color. Example: organic matter likes to absorb 254nm ultraviolet light; nitrate is sensitive to 220nm. Refraction (light bending degree): the more salt in water, the higher the refractive index, and the light bending angle at the interface will change. Example: the displacement amount of the light beam, and the shape and area of the light beam projected on the image sensor 115 (the projection shape is different when vertically irradiated and when the light is bent), are observed by the image sensor 115, and the critical angle position is calculated to calculate the salinity.

[0034] Under the action of gravity, the stressed floating plate 131 falls in the position in contact with the buoyancy paddle 134, or the lowest position, at this time the intermittent starting electromagnet 150, the electromagnet 150 energized state will generate magnetic force, electromagnet 150 will attract the adjusting turntable 137 and electromagnet 150 contact (adjusting turntable 137 in the adjusting turntable mounting sleeve 138 on the assembly mode, allows the adjusting turntable 137 in the adjusting turntable mounting sleeve 138 along the axial displacement, namely the installation of virtual position), the adjusting turntable 137 is attracted by the electromagnet 150 limit, resulting in the adjusting turntable 137 can not rotate (the beginning of the adjusting turntable 137 in the adjusting turntable mounting sleeve 138 free rotation, gear ring 139 rotation will drive the revolution and rotation of planetary gear 140, because the buoyancy paddle 134 and the center gear 141 are the load end, especially when the buoyancy paddle 134 and the stressed floating plate 131 are in contact state, the friction between the buoyancy paddle 134 and the stressed floating plate 131 further increases the load (can not overcome the load, resulting in the revolution of planetary gear 140), which will cause the gear ring 139 to drive the planetary gear 140 and the adjusting turntable 137 to revolve, but not directly drive the center gear 141 and the buoyancy paddle 134 to rotate), then all the power will be transmitted from the driving main shaft 147 to the gear ring 139, the gear ring 139 to the rotation of the planetary gear 140, the planetary gear 140 to the center gear 141, the center gear 141 through the floating transmission shaft 142 to the buoyancy paddle 134, the rotation of the buoyancy paddle 134 will drive the air to the stressed floating plate 131, causing the stressed floating plate 131 to float upwards, that is, the pressure below the stressed floating plate 131 is greater than that above, so that the stressed floating plate 131 moves along the drain pipe 128 to the ultraviolet light emitting unit 121 direction, this process will cause the inside mirror 132 and the outside mirror 133 to move linearly outside the rectangular transparent detection channel 129, because the electromagnet 150 is intermittently started, so the inside mirror 132 and the outside mirror 133 outside the rectangular transparent detection channel 129 are reciprocating linear motion, used to change the position of the ultraviolet light beam irradiated on the rectangular transparent detection channel 129, that is, change the detection position.Therefore, by reducing the magnetic force generated by electromagnet 150, the sliding friction between adjusting turntable 137 and electromagnet 150 is reduced, which will cause adjusting turntable 137 and planetary gear 140 to still revolve, at this time the rotation speed of center gear 141, floating transmission shaft 142 and buoyancy paddle 134 will be reduced, because part of the power is released from the friction between adjusting turntable 137 and electromagnet 150, at this time the thrust of buoyancy paddle 134 on force-bearing float 131 will be reduced, causing the movement speed of force-bearing float 131 on drainage pipeline 128 to be reduced, so by controlling the magnetic force of electromagnet 150 when it is started, the speed of force-bearing float 131 moving on drainage pipeline 128 towards ultraviolet light emitting unit 121 can be controlled, and the movement of force-bearing float 131 on drainage pipeline 128 towards bottom annular cavity 130 is ignored (limit switches are arranged on top annular cavity 127 and bottom annular cavity 130 to contact force-bearing float 131, for monitoring the position of force-bearing float 131, so that image sensor 115 only records the data of the movement of force-bearing float 131 towards ultraviolet light emitting unit 121, that is, the moment when force-bearing float 131 is separated from the limit switch on bottom annular cavity 130 to the moment when it contacts the limit switch on top annular cavity 127). In this way, the relative position (detection position) of inner reflector 132 and outer reflector 133 on rectangular transparent detection channel 129 can be controlled, because the saline water in rectangular transparent detection channel 129 is in a flowing state, when the flow rate is close to the same as the movement speed of force-bearing float 131, inner reflector 132 and outer reflector 133, the water quality of the saline water at a certain position is detected, otherwise when the flow rate is different from the movement speed of force-bearing float 131, inner reflector 132 and outer reflector 133, the water quality of the saline water at multiple positions is detected, the above are random, which is caused by the cooperation mode of force-bearing float 131 and buoyancy paddle 134 (instability of air flow) and the randomness of the magnetic force of electromagnet 150. To improve the randomness of saline water quality detection.

[0035] The ultraviolet light emitting unit 121 and the image sensor 115 generate heat during operation, which is transferred to the inner evaporation cavity 149 and the outer evaporation cavity 113, and then absorbed by the electronic fluorination liquid inside the inner evaporation cavity 149 and the outer evaporation cavity 113. The electronic fluorination liquid absorbing heat evaporates and then moves to the inside of the inner heat sink 114 and the outer heat sink 111. The heat dissipation motor 108 is started, and the heat dissipation motor 108 drives the heat dissipation fan blade 109 to rotate. The heat dissipation fan blade 109 drives the external air to move to the center of the inner heat sink 114, the auxiliary heat sink 112, and the outer heat sink 111 surrounded by the support plate 106 and the air inlet 107, and then flows from the center to the outside, thereby cooling the inner heat sink 114 and the outer heat sink 111. In turn, the gaseous electronic fluorination liquid condenses and falls into the corresponding inner evaporation cavity 149 and outer evaporation cavity 113 again to absorb heat. Cooling the ultraviolet light emitting unit 121 ensures the working efficiency of the ultraviolet light emitting unit 121, and cooling the image sensor 115 can reduce the thermal noise generated by the image sensor 115 during long-term operation, thereby improving the sensitivity and accuracy of detecting light.
