Description

Technical Field

[0001] The invention relates to the technical field of water quality monitoring, and in particular to a full-automatic submersible long-term water sample collector. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In order to objectively evaluate the water quality of rivers and oceans, in addition to the above monitoring items, it is sometimes necessary to measure the flow rate and flow.

[0003] The existing monitoring method is mainly a method of regular fixed-point sampling by manpower, and certain sampling equipment is used as an auxiliary, such as patent announcement number CN109946120A, named a submersible water sample collector, patent announcement number CN109900518A, named a water quality sampler. In recent years, there are also some automated equipment, such as patent announcement number CN107402143A, named a ship-borne automatic water quality sampler.

[0004] However, these devices all have certain problems. For example, the submersible water sample collector provided by patent announcement number CN109946120A is very easy to roll over in relatively turbulent water. On the one hand, the sampling process is complicated and the instrument is easily damaged; on the other hand, the rolling collector is very easy to pull people into the water, which is dangerous. The ship-borne automatic water quality sampler provided by patent announcement number CN107402143A is located on the water surface, which affects navigation and also brings dangers. According to the applicant's long-term work experience, the maintenance of this patent and similar water equipment requires work on the water, which is easy to fall into the water, bringing danger to the maintenance personnel. Summary of the invention

[0005] The purpose of the present invention is to provide a fully automatic submersible long-term water sample collector, which has the effect of long-term automatic monitoring of water quality underwater.

[0006] The above technical purpose of the present invention is achieved through the following technical scheme: it includes a shell, a detection mechanism coaxial with the shell, a buoyancy device sleeved on the detection mechanism, and an anti-slip device arranged on the shell, the shell is provided with a water inlet at one end and a water outlet at the other end, the water outlet is a closed end, and a sand-proof net is arranged on the water inlet, the detection mechanism is fixed to the shell by a plurality of mounting rings, and a communication module is also arranged in the detection mechanism.

[0007] By adopting the above-mentioned technical scheme, the shell of a fully automatic submersible long-term water sample collector provided by the present application has a special shape, which can ensure that when the water flow has a certain flow rate, the water outlet can be located upstream of the water flow and the water inlet can be located downstream of the water flow, on the one hand to avoid the equipment from rolling, and on the other hand to increase the rationality of detection; the detection results are transmitted to the user in real time through the communication module, and the communication module can be a GSM communication module or a WiFi communication module.

[0008] The present invention is further configured as follows: the surface of the shell is evenly provided with light-emitting sheets, and the light-emitting sheets are fitted to the surface of the shell.

[0009] The present invention is further configured as follows: one or more of a fluorescent film, a reflective film or an LED lamp is arranged inside the light-emitting sheet.

[0010] By adopting the above technical solution, the equipment needs to be repaired after being used for a certain period of time or having a malfunction. However, the equipment is usually at the bottom of the water and difficult to observe directly, so a light-emitting sheet is provided to make the equipment more visible and convenient for recovery. In some special cases, a broken chain is also easy to find.

[0011] The present invention is further configured as follows: the anti-slip device includes a water pipe arranged at the end of the shell, the water pipe is connected to the detection mechanism, a first clamping shell and a second clamping shell are sleeved on the water pipe, an anti-slip line is arranged on the detection mechanism, the first clamping shell is fixedly connected to the shell, and the second clamping shell is at least 0.5m away from the first clamping shell.

[0012] The present invention is further configured as follows: the first clamping shell comprises two clamping flaps connected by a hinge, and a clamping groove is provided on the outer side of the clamping flaps.

[0013] By adopting the above technical solution, the detection mechanism is connected to the anti-slip line, and the anti-slip line is clamped with the water diversion pipe through the clamping shell, so as to prevent the recoil force of the detection mechanism when pumping water from impacting the detection mechanism off the shell, causing danger, and also reducing the number of maintenance and maintenance costs; the clamping groove is convenient for using external accessories such as steel hoops to clamp the clamping petals.

[0014] The present invention is further configured as follows: the detection mechanism includes a spindle housing arranged in the housing, a water pump and a power supply system are arranged in the spindle housing, and the power supply system is one of a battery box or a cable interface.

[0015] By adopting the above technical solution, the water quality can be regularly tested underwater.

[0016] The present invention is further configured as follows: one end of the anti-slip line is arranged on the main shaft housing, and the other end of the anti-slip line is fixed on the water diversion pipe through the first clamping shell and the second clamping shell.

[0017] By adopting the above technical solution, the mechanism in the equipment that is most likely to slip is the main shaft housing. By providing an anti-slip line on the main shaft housing, the risk of the main shaft housing falling off with the water pump can be reduced, and the anti-slip line can be clamped by utilizing the clamping force of clamping the water pipe.

[0018] The present invention is further configured as follows: the mounting ring comprises a threaded ring arranged on the shell and a fixing ring threadedly connected to the threaded ring, at least three fixing feet are evenly distributed circumferentially on the fixing ring, the fixing feet just fit with the spindle shell, and the material of the fixing feet is at least one of iron, stainless steel, copper, and plastic.

[0019] By adopting the above technical solution, river bottom turbulence is difficult to avoid, so three fixed supports are set to prevent the main shaft housing from vibrating and avoid damage to the instrument.

[0020] The present invention is further configured as follows: a positioning module and a communication module are also provided in the power supply system.

[0021] By adopting the above technical solution, the positioning module can select the Beidou positioning module or the GPS positioning module to assist in building the real-time point position. At the same time, it can be used in conjunction with reflective sheets to find equipment. There is no need for high-precision positioning, which can save power consumption.

[0022] The present invention is further configured as follows: the buoyancy device includes a plurality of inflatable structures sleeved between the main shaft housing and the shell, the inflatable structure is one or more of annular, spherical or straight cylindrical, and there is at least one mounting ring between the inflatable structure and the water inlet.

[0023] By adopting the above technical solution, an inflatable structure can be arranged in a plurality of cavities between the mounting ring and the shell, so that the overall buoyancy structure is more reasonable.

[0024] The beneficial effects of the present invention are:

[0025] 1. The solution provided in this application is durable and easy to replace, and is suitable for long-term lurking underwater for water sample collection. It solves the problem that the sampling ship has large surface resistance, high difficulty in fixing, and is easy to be entangled with a large amount of aquatic plants and debris. At the same time, the structure is firm and easy to install.

[0026] 2. The solution provided in this application greatly reduces the difficulty of finding underwater equipment and reduces the risk of equipment loss through the combination of communication modules and reflective sheets.

[0027] 3. Zero maintenance, lower operating costs, and reduce the risks of water operations; increase the effective working time of equipment, improve the continuity of environmental monitoring sampling, reduce monitoring blind spots caused by equipment maintenance, make monitoring data more complete, and provide more scientific and effective data for environmental testing.

[0028] 4. Low loss. The equipment works underwater for a long time, reducing the sunshine time and the time of natural oxidation in the air, thereby extending the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
