Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, and in particular to a composite water quality multi-parameter online automatic monitoring instrument. Background Art

[0002] In recent years, composite water quality multi-parameter online automatic monitoring instruments have made remarkable progress in technology and application. Modern composite water quality monitoring instruments can simultaneously monitor multiple water quality parameters, such as pH, conductivity, dissolved oxygen, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, temperature, etc. Some more advanced equipment can also monitor biological indicators, such as chlorophyll, blue-green algae, etc. As the accuracy and stability of sensors continue to improve, they can provide more accurate and reliable measurement results. For example, optical sensors can achieve high-sensitivity detection of complex parameters such as COD and TOC.

[0003] Some composite water quality multi-parameter online automatic monitoring instruments in the prior art usually have the defect that the dustproof net is exposed to the outside for a long time, which is easy to accumulate dust, mud and other particulates. These substances may enter the interior of the device and adhere to the surface of the sensor, resulting in a decrease in sensor sensitivity. They may also be mixed into the water sample, thereby affecting the reliability of the analysis results. Although some monitors already have the ability to protect the filter net, excessive protection may cause poor air circulation inside the device in a high temperature environment, causing the device to overheat and affecting its stability and lifespan; and the monitors are usually deployed around the water environment. When the monitor is installed at a low position and the wind is strong, waves on the water surface may splash onto the device or even directly enter the device. Although some monitors are connected to a drain pipe at the bottom to discharge the accumulated water, the risk of waves entering the device is also increased. Summary of the invention

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1 Reference Figure 1~Figure 3 , which is the first embodiment of the present invention, provides a composite water quality multi-parameter online automatic monitoring device, the device comprising: Monitor body 100; It should be noted that the monitor body 100 adopts the GL460J A cabinet model with a width of 500mm, a depth of 470m, and a height of 1575mm.

[0030] The protection mechanism 200 includes a dustproof component 201 that can prevent external dust from entering the interior of the monitor body 100, a transmission component 202 that can move linearly according to the temperature change of the monitor body 100, a heat dissipation component 203 that prevents overheating of the monitor body 100 through the power of the transmission component 202, a drainage component 204 that can drain the accumulated water inside the monitor body 100, and a sealing component 205 that can automatically seal the drainage port after the accumulated water is drained.

[0031] It should be noted that the dustproof component 201 is used to prevent dust from passing through the heat dissipation port inside the monitor body 100 and adhering to the sensor surface, thereby reducing the sensitivity of the sensor; the transmission component 202 can drive the heat dissipation component 203 to open when the temperature inside the monitor body 100 rises, thereby removing the obstruction of the dustproof component 201 and the heat dissipation port; after the temperature drops, the heat dissipation component 203 is driven to close to protect the dustproof component 201 without the need for additional power source and manual intervention; the drainage component 204 is used to quickly drain the accumulated water when water enters the monitor body 100; the sealing component 205 can quickly close the drainage component 204 after the drainage component 204 has drained the accumulated water, so as to prevent waves from entering the monitor body 100 through the drainage component 204.

[0032] Specifically, the dustproof component 201 includes a dustproof net 201a fixedly installed on the outer surface of the monitor body 100, a plurality of support shafts 201b fixedly installed on the outer surface of the monitor body 100 through bearings, a baffle 201c fixedly sleeved on the outer surface of the support shaft 201b and used in conjunction with the dustproof net 201a, and a top cover 201d fixedly connected to the top of the monitor body 100 and used in conjunction with the baffle 201c.

[0033] It should be further explained that, when the baffles 201c are closed, they can form a closed cylindrical shape with the top cover 201d, and shield the dustproof net 201a to prevent the dustproof net 201a from being exposed.

[0034] Furthermore, the dustproof net 201a is located at the heat dissipation port of the monitor body 100, the support shafts 201b are distributed in a circular array on the outside of the dustproof net 201a, and the top cover 201d is located directly above the baffle 201c.

[0035] Among them, the transmission assembly 202 includes a heat-conducting sleeve 202a fixedly installed on the outer surface of the monitoring instrument body 100, a heat expansion block 202b arranged in the inner cavity of the heat-conducting sleeve 202a, a sliding block 202c in sliding contact with the inner wall of the heat expansion block 202b, a connecting rod 202d fixedly connected to the outer surface of the sliding block 202c, a driving block 202e fixedly connected to the outer end surface of the connecting rod 202d, and a spring 202f sleeved on the outer surface of the sliding block 202c and used in conjunction with the sliding block 202c.

[0036] It should be explained that the heat-conducting sleeve 202a is made of boron nitride with a thermal rate of up to 200-400 W / m·K, which can effectively transfer the internal temperature of the monitor body 100 to the thermal expansion block 202b. The thermal expansion block 202b is made of a nickel-titanium alloy material that can rapidly expand and increase in volume when heated, and automatically recover after heat dissipation. After being heated, the thermal expansion block 202b can expand and squeeze the sliding block 202c, so that the sliding block 202c drives the connecting rod 202d and the driving block 202e to move in a straight line, and applies a pressure to the spring 202f.

[0037] Preferably, the outer surface of the sliding block 202c is in sliding contact with the inner surface of the heat-conducting sleeve 202a, and the outer end surface of the spring 202f is fixedly connected to the outer surface of the sliding block 202c.

[0038] It should be noted that the heat dissipation assembly 203 includes a transmission column 203a that is in sliding contact with the inner wall of the driving block 202e, a connecting block 203b fixedly installed on the outer end surface of the transmission column 203a, a turntable 203c fixedly connected to the outer surface of the connecting block 203b, a plurality of fixed columns 203d fixedly installed on the outer surface of the turntable 203c, a transmission block 203e that is slidably sleeved on the outer surface of the fixed column 203d and used in conjunction with the support shaft 201b, and a circular guide rail 203f fixedly connected to the outer surface of the monitoring instrument body 100 and used in conjunction with the turntable 203c.

[0039] Furthermore, the inner surface of the transmission block 203e is fixedly connected to the outer surface of the support shaft 201b, and the turntable 203c is rotatably sleeved on the outer surface of the circular guide rail 203f.

[0040] It needs to be explained that when the driving block 202e moves in a straight line, it can squeeze the transmission column 203a, and the circular guide rail 203f limits the turntable 203c and the connecting block 203b, so that the transmission column 203a is squeezed by the driving block 202e, driving the connecting block 203b and the turntable 203c to rotate, and then the turntable 203c drives several fixed columns 203d to rotate synchronously, so that the fixed column 203d squeezes the transmission block 203e, and the transmission block 203e drives the support shaft 201b and the baffle 201c to rotate, so as to achieve the effect of driving the baffle 201c to open when the internal temperature of the monitor body 100 rises, so as to prevent the internal overheating of the monitor body 100.

[0041] When in use, the monitor body 100 is turned on to monitor the water quality in real time. When the internal temperature of the monitor body 100 rises, the internal temperature of the monitor body 100 is transmitted to the heat expansion block 202b through the heat conductive sleeve 202a, so that the heat expansion block 202b expands rapidly and increases in volume, and squeezes the sliding block 202c, so that the sliding block 202c drives the connecting rod 202d and the driving block 202e to move linearly, and applies a pressure to the spring 202f, so that the driving block 202e squeezes the transmission column 203a, and the rotating disk 203a is pressed by the circular guide rail 203f. 03c and the limit of the connecting block 203b, the transmission column 203a is squeezed by the driving block 202e, driving the connecting block 203b and the rotating disk 203c to rotate, and then the rotating disk 203c drives the plurality of fixed columns 203d to rotate synchronously, so that the plurality of fixed columns 203d squeeze the plurality of transmission blocks 203e at the same time, so that the transmission block 203e drives the support shaft 201b and the baffle 201c to rotate at the same time, so as to achieve the effect of driving the baffle 201c to open when the temperature inside the monitor body 100 rises, thereby preventing the monitor body 100 from overheating; After the internal temperature of the monitor body 100 drops, the heat expansion block 202b dissipates heat and automatically recovers, the spring 202f loses pressure, and the sliding block 202c is reset by the reaction force of the spring 202f, so that the sliding block 202c drives the connecting rod 202d and the driving block 202e to move in a straight line in the opposite direction, and then the driving block 202e cooperates with the transmission column 203a to drive the connecting block 203b, the turntable 203c and the plurality of fixed columns 203d to rotate in the opposite direction, and the plurality of fixed columns 203d cooperate with the plurality of transmission blocks 203e to drive the support shaft 201b and the baffle 201c to rotate in the opposite direction, so as to achieve the effect that when the internal temperature of the monitor body 100 drops, the baffle 201c is driven to close to prevent the dustproof net 201a from being exposed to the outside for a long time, causing dust to enter the inside of the monitor body 100 through the heat dissipation port.

[0042] In summary, the dustproof component (201) can effectively prevent external dust from entering the interior of the monitor body (100). The transmission component (202) and the heat dissipation component (203) cooperate to drive the baffle 201c to open when the temperature inside the monitor body 100 rises, thereby preventing the monitor body 100 from overheating. When the temperature inside the monitor body 100 drops, the baffle 201c is driven to close, thereby preventing the dustproof net 201a from being exposed to the outside for a long time, thereby preventing dust from entering the monitor body 100 through the heat dissipation port. This can prevent damage to electronic components or performance degradation due to overheating, while reducing the amount of dust, mud, and other particles from entering the device through the heat dissipation port.

[0043] Example 2 Reference Figure 4~Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: this embodiment provides a drainage component 204 that can drain the accumulated water inside the monitoring instrument body 100, and a sealing component 205 that can automatically seal the drainage port after the accumulated water is drained.

[0044] Furthermore, the drainage assembly 204 includes a guide tube 204a connected to the bottom of the monitoring instrument body 100, a water storage box 204b connected to the other end of the guide tube 204a, and an L-shaped drainage pipe 204c fixedly connected to the inner surface of the water storage box 204b.

[0045] When water enters the monitoring instrument body 100 , the accumulated water can enter the water storage box 204b through the guide pipe 204a and then be discharged through the L-shaped drainage pipe 204c.

[0046] Furthermore, the sealing assembly 205 includes a float 205a arranged in the inner cavity of the water storage box 204b, a driving rod 205b fixedly connected to the outer surface of the float 205a, a transmission rod 205c hinged to the outer surface of the driving rod 205b, a driven rod 205d hinged to the other end of the transmission rod 205c, and a blocking block 205e hinged to the outer surface of the driven rod 205d and used in conjunction with the L-shaped drain pipe 204c.

[0047] What should be explained further is that when the water level inside the water storage box 204b rises, it can drive the float 205a to rise synchronously, so that the float 205a drives the driving rod 205b to move, and then through the cooperation of the driving rod 205b and the transmission rod 205c, drives the driven rod 205d to move, so that the driven rod 205d drives the blocking block 205e to rise, so that the blocking block 205e releases the blockage of the L-shaped drain pipe 204c, so that the accumulated water can be discharged smoothly.

[0048] Specifically, the outer end face of the driving rod 205b is hinged to the outer surface of the L-shaped drain pipe 204c, the outer end face of the driven rod 205d is hinged to the outer surface of the side of the L-shaped drain pipe 204c away from the driving rod 205b, and the blocking block 205e is located in the inner cavity of the L-shaped drain pipe 204c.

[0049] When in use, when water enters the monitor body 100, the accumulated water enters the water storage box 204b through the guide tube 204a. When the water level inside the water storage box 204b rises, the accumulated water drives the float 205a to rise synchronously, so that the float 205a drives the driving rod 205b to move, and then the driving rod 205b cooperates with the transmission rod 205c to drive the driven rod 205d to move, so that the driven rod 205d drives the blocking block 205e to rise, so that the blocking block 205e releases the blockage of the L-shaped drain pipe 204c, so that the accumulated water can be discharged smoothly. After the accumulated water inside the water storage box 204b is drained: the float 205a loses its buoyancy and descends due to gravity, and the float 205a drives the driving rod 205b to move in the opposite direction, and then the driving rod 205b cooperates with the transmission rod 205c to drive the driven rod 205d to move in the opposite direction, so that the driven rod 205d drives the blocking block 205e to descend, so that the blocking block 205e blocks the outlet of the L-shaped drain pipe 204c, so as to achieve the effect of automatically blocking the drain outlet after the accumulated water inside the monitoring instrument body 100 is drained.

[0050] In summary, through the cooperation between the components in the drainage component 204 and the sealing component 205, the drainage outlet can be automatically sealed after the accumulated water inside the monitoring instrument body 100 is discharged, thereby effectively preventing secondary water ingress due to wave splashing, ensuring that the equipment remains dry in high humidity or water environments, so as to reduce the risk of corrosion and short circuit of electrical components inside the equipment.
