Detailed Description
For a further understanding of the invention, its features and advantages, the following examples are set forth in detail:
referring to fig. 1, the automatic sampling and monitoring system based on a marine station Wen Yanjing of the present invention comprises a water sample collecting and monitoring device 1 and a water sample distributing device 2. The water sample collecting and monitoring device 1 is divided into a buoyancy and monitoring assembly in Wen Yanjing and a sampling pump and a filtering assembly outside the warm salt well. The buoyancy and monitoring assembly installed in the warm salt well is lifted along with the lifting of the water level. The water sample distribution device 2 is arranged on the indoor wall of the ocean station and is used for safely conveying collected seawater samples to various water quality analysis instruments through a series of distribution pipelines.
Referring to fig. 2 to 5, it can be seen that: the buoyancy and monitoring assembly of the water sample collecting and monitoring device 1 comprises a plurality of guide rails 1-3 which are sequentially connected from top to bottom and a buoyancy ring frame 1-6 which is lifted along the guide rails 1-3, wherein the buoyancy ring frame 1-6 is provided with a buoyancy ring 1-5 and a plurality of monitoring instruments. Wherein the guide rail 1-3 is used for eliminating the rotation of the buoyancy ring frame 1-6 and the buoyancy ring 1-5 on one hand, and is used as a track for lifting and moving the buoyancy ring frame 1-6 and the buoyancy ring 1-5 on the other hand. Specifically:
the buoyancy ring frame 1-6 is a welding assembly part and comprises a central square tube 1-6-1 positioned in the center, a pallet disc 1-6-3 is fixedly arranged at the middle upper part of the central square tube 1-6-1, and a bottom circular ring 1-6-6 is fixedly arranged at the bottom of the buoyancy ring frame by adopting a plurality of radiating ribs 1-6-7; a plurality of vertical rods 1-6-5 are arranged between the supporting plate disc 1-6-3 and the bottom circular ring 1-6-6, and a middle circular ring 1-6-4 is fixedly arranged in the middle of each vertical rod 1-6-5. The supporting plate disc 1-6-3, the middle circular ring 1-6-4, the bottom circular ring 1-6-6 and the vertical rods 1-6-5 form a protection squirrel cage, and the protection is provided for a plurality of monitoring instruments in the interior. The outer diameter of the protection squirrel cage is smaller than the inner diameter of Wen Yanjing, when the tide level rises and falls, the buoyancy ring frame 1-6 and the accessory parts thereof vertically rise and fall along the axial direction of the salt well under the buoyancy action of the buoyancy ring 1-5, the protection squirrel cage effectively avoids the possible collision between each monitoring instrument and the well wall, and plays a role in protecting the monitoring instrument.
In the embodiment, the monitoring instrument comprises a warm salt sensor, a turbidity sensor, a chlorophyll sensor and a multiparameter water quality instrument which are arranged and fixed on three outer vertical surfaces at the middle and lower parts of a central square tube 1-6-1; a sampling bottom valve is also arranged on the other outer vertical surface of the middle lower part of the central square tube 1-6-1. The temperature salt sensor, the turbidity and chlorophyll sensor and the multi-parameter water quality instrument are used for monitoring various water quality parameters such as the pH value, the dissolved oxygen, the temperature, the salinity, the turbidity, the chlorophyll and the like of the seawater, and the sampling bottom valve can ensure that the seawater in the vertical sampling tube in the well is not emptied, so that the sampling peristaltic pump is beneficial to pumping the seawater. In addition, the filter has a filtering function and is used for filtering out massive particles in a sampled water area.
The buoyancy ring 1-5 is a cylinder with a central square hole, a polyethylene foaming light floating body material is used as a base material, and a polyurea protection layer with a certain thickness is sprayed outside the buoyancy ring. The buoyancy ring 1-5 is fixedly arranged above the supporting plate disc 1-6-3, and a plurality of 4 threaded rods 1-6-2 are welded on the upper surface of the supporting plate disc 1-6-3; the center of the buoyancy ring 1-5 is provided with a center square hole, 4 cable holes and 4 screw holes which are axially communicated are arranged around the center square hole, the upper end of the center square tube 1-6-1 is positioned in the center square hole, each threaded rod 1-6-2 is positioned in each screw hole, and wiring and sampling pipelines of each monitoring instrument are arranged in each cable hole in a penetrating mode.
As shown in the figure, 4 screw holes and 4 cable holes are uniformly distributed around the central square hole, perpendicular to the cross section. The buoyancy ring 1-5 is arranged above the pallet disc 1-6-3 by passing a threaded rod 1-6-2 through a threaded rod hole. Further, the cable holes of the buoyancy rings 1-5 and the adjacent screw holes form an included angle of 45 degrees in the circumferential direction, cables and sampling pipelines of all monitoring instruments pass through the cable holes and then are gathered into a bundle, are wrapped neatly, are wound around the guide rails 1-3 for a plurality of circles and then are discharged Wen Yanjing, and are connected to an electrical control system.
The buoyancy rings 1-5 are orange or yellow, the inner walls of all cable holes are smooth, and chamfers are arranged at the two ends, so that the cable connection of the monitoring instrument can be prevented from being blocked.
When the water level is high, the wound cables can be piled up; at low water levels, the pitch of the coiled cable increases. The tidal range of most sea areas in China is 4-5 meters, the winding turns are 5-6, and the rest cables and sampling pipelines are straightened. The upper guard rail 1-4 is used for collecting the wound pipeline, and avoiding scratch or blockage with the well wall caused by loosening. The upper guardrail 1-4 is a welding assembly and comprises a top circular ring 1-4-1 positioned above and a bottom plate 1-4-3 positioned below, wherein the top circular ring 1-4-1 and the bottom plate 1-4-3 are welded together through 8 connecting vertical rods 1-4-2 distributed circumferentially. A central square hole which can be penetrated by the central square tube 1-6-1 is cut in the center of the bottom plate 1-4-3, and 4 cable holes and 4 screw holes which are positioned at the same positions as the cable holes and the screw holes on the buoyancy ring 1-5 are formed around the central square hole. The buoyancy ring 1-5 is fixed between the bottom plates 1-4-3 of the upper guardrails 1-4 and the pallet discs 1-6-3 of the buoyancy ring frame 1-6 by threaded rods 1-6-2. The outer diameter of the upper guardrail 1-4 is equal to the outer diameters of the buoyancy ring 1-5 and the buoyancy ring frame 1-6, but is smaller than the inner diameter of Wen Yanjing.
The upper surface of the bottom plate 1-4-3 of the upper guardrail 1-4 is provided with two hanging rings 1-4-4, a sling connected to the hanging rings 1-4-4 in a fastening way is connected to a winding device through a fixed pulley 1-2, and when maintenance operation is needed, the sling can be wound and unwound through the winding device, so that the buoyancy and monitoring assembly of the water sample collecting and monitoring device 1 is lifted or put down.
The main body of the guide rail 1-3 is a square pipe 1-3-3 made of thin-wall stainless steel, an upper hinge 1-3-1 is arranged at the upper end of the square pipe 1-3-3, a lower hinge 1-3-5 is arranged at the lower end of the square pipe, and the lower hinge 1-3-5 of each guide rail 1-3 is hinged with the upper hinge 1-3-1 of the guide rail 1-3 below the lower hinge. The upper hinge 1-3-1 of the uppermost first section of guide rail 1-3 is connected to the protection frame of the fixed pulley 1-2 through a pin shaft. The fixed pulley 1-2 is also arranged on the hanging disc 1-1 through a pin shaft, the hanging disc 1-1 is fixed on the roof of the ocean station through an expansion bolt, and the center of the hanging disc 1-1 is coaxial with the center of Wen Yanjing. The tail end of the last guide rail 1-3 positioned at the lowest part is welded with an anti-drop flange perpendicular to the guide rail 1-3, so that the buoyancy ring frame 1-6 penetrating through the guide rail 1-3 is prevented from dropping off from the guide rail 1-3 when the water level is extremely low. The whole guide rail is suspended in Wen Yanjing, and the pin shafts of two adjacent groups of hinges from top to bottom are mutually perpendicular. The purpose is to ensure that the guide rail 1-3 has a certain degree of freedom on any horizontal plane, left and right or front and back, and the flexible guide rail can counteract the impact of sea waves. Furthermore, each guide rail 1-3 is of hollow sealing design, with the aim of reducing weight and providing a certain buoyancy in the water.
The buoyancy ring frame 1-6 penetrating the suspension guide rail 1-3 carries various monitoring instruments and cables thereof, and floats on the water surface by virtue of the buoyancy provided by the buoyancy ring 1-5. Through buoyancy calculation, various monitoring instruments and sampling bottom valves are ensured to be positioned in the surface sea water. Along with the rise and fall of tide level, the water pump moves up and down along the guide rail. The guide rail 1-3 can only slightly swing left and right or back and forth but cannot rotate, so that the possible rotation of the buoyancy ring frame 1-6 due to the impact of the surge and wave in the salt well is effectively avoided, and the damage caused by abnormal winding of various pipelines attached to the buoyancy ring frame 1-6 is avoided. In addition, a certain fit clearance is reserved between the guide rail 1-3 and the central square tube 1-6-1 on the buoyancy ring frame 1-6, so that the buoyancy ring frame 1-6 floating on the water surface cannot incline due to self and external factors, and the vertical lifting movement of the whole buoyancy ring frame 1-6 is smoother.
In the initial installation and the subsequent maintenance process of the system, the guide rail 1-3 is required to be hoisted, in order to facilitate hoisting operation, an upper hoisting circular pipe 1-3-2 and a lower hoisting circular pipe 1-3-4 are arranged on the square pipe 1-3-3 of the guide rail 1-3, and the axes of the upper hoisting circular pipe 1-3-2 and the lower hoisting circular pipe 1-3-4 are vertical and respectively transversely penetrate through the square pipe 1-3-3.
