Description
Technical Field
The utility model relates to a special well-flushing sampling pump of groundwater environment monitoring well for the well-flushing and the sample work of groundwater monitoring well belong to groundwater environment monitoring well equipment technical field.
Background
With the development of socioeconomic in China, the environmental problem of underground water is increasingly outstanding, and the underground water in partial areas is seriously polluted. Scientific and accurate investigation, evaluation and treatment of contaminated groundwater is becoming increasingly important. At present, the main means of groundwater pollution investigation and water quality monitoring is to take samples in groundwater monitoring wells for testing. When underground water sampling is carried out, the quality and effectiveness of the underground water quality detection result are directly related to the aspects of whether the underground water environment monitoring well is fully washed, the selection of sampling appliances and the like. The developed countries in foreign countries attach great importance to the underground water sampling technology and form large-scale and systematic sampling appliance products; however, the underground water sampling technology, especially the sampling equipment, is relatively late in the beginning of China, and the technology is relatively lagged abroad.
The well washing is a process that a well washing medium is injected by pumping equipment through a shaft or a drill rod in the process of well repairing operation and substances (liquid phase, solid phase and gas phase) in the shaft are carried to the ground so as to change the property of the medium in the shaft to meet the operation requirement, and mainly comprises three continuous operations of slurry changing, well washing and water pumping.
According to market investigation, the sampling devices which are common in China at present are roughly divided into four types: a sampling cylinder type sampler, an inertia type sampler, a gas drive type sampler and a diving and electric pump type sampler. The performances of all appliances are different, low-price pumps such as an inertial sampler, a submersible pump and the like have large caliber flow and low sampling quality, and are difficult to meet the increasingly strict requirements of well washing and sampling; and the air bag pump and the U-shaped tube pump which can meet the requirements need to carry equipment such as a console and the like, and have the problems of complex operation, low efficiency, short service life, high material consumption and the like.
When the underground water environment monitoring well is built, the sediment content is higher, so the requirement on well washing work is more strict, and the well washing is carried out until sand is cleaned, and at least 3-5 times (about 50-500 m) of the water body in the well pipe needs to be cleaned3Groundwater volume). The pump commonly used for well washing in the domestic market at present is a submersible pump, but the pump cannot be used as a well washing and sampling tool due to large diameter or has devices such as a generator, an external power supply and the like, so that the pump is heavy and tedious to use; the manual bailer tube has extremely low efficiency and wastes time and labor when used for water lifting; although there is some gasThe bladder pump, the small-diameter multifunctional centrifugal pump and the like can be used optionally, but have the defects of high price, large daily loss and low flow rate, so that the well washing efficiency is poor, and the sampling cost is high.
At present, a plurality of technical methods for well construction specifications and sampling of underground water environment monitoring wells are issued successively in China, wherein the outer diameter design range of well pipes of the monitoring wells is regulated to be 50-200 mm, and the water level burial depth range in the underground water monitoring wells is 2-100 m in general. Well washing is carried out in time before collecting water samples, and the using amount of the washing underground water is not less than 3-5 times of the well volume (the well washing water amount is about 10-100 m)3). The diameter of the submersible pump is larger than the hole diameter of part of the monitoring wells, so that the application range is limited; the flow rate of a part of air bag pumps is low, the efficiency is low, the price is high, and the cost performance is not high; the efficiency of the manual bailer tube water lifting well washing is extremely low, and a large amount of manpower and material resources are consumed.
In the underground water quality standard GB/T-14848-2017 which is implemented in 5, 1 and 2018 in China, the monitoring indexes are increased from 39 indexes of the original standard to 93 indexes, wherein 47 indexes of organic compounds are increased, and the requirements on underground water sampling instruments and methods are also increased: the sampling flow rate is required to be lower than 0.5L/min while the disturbance to the underground water is reduced as much as possible. When organic sample sampling is carried out, the submersible pump with low price has large flow and large disturbance to underground water, and is not suitable for sampling of organic pollutants such as volatility, semi-volatility and the like; the air bag pump is high in price, the sediment in underground water has large loss to the air bag pump, the cost performance is not high, and the popularity is low; both the submersible pump and the air bag pump need a generator or an external power supply and other devices, and are complex, heavy and not easy to carry, so that the sampling efficiency is low.
The sampling pumps for underground water mainly comprise the following pumps: chinese patent CN207866560U "groundwater sampling device", can prevent through setting up the transition bottle that water in the collecting bottle directly suck the sampling pump backward after full, protect the sampling pump, in first solenoid valve can block the outside air entering transition bottle, avoid the sampling pump evacuation again, the second solenoid valve can avoid humid air to get into the sampling pump, prolongs the life of sampling pump, reduce cost. But are primarily suitable for sampling and are inefficient for flushing. The Chinese patent CN203587386U 'built-in inertial underground water sampling pump' is composed of a sampling tube, a water-passing baffle ring, a ball seal and a base which are arranged in the sampling tube, and solves the problems of large external diameter, poor integrity, well pipe abrasion and the like of the external inertial underground water sampling pump. But needs external power supply and other devices, and is tedious to use, time-consuming and labor-consuming. Chinese patent CN205506471U "a hand-held sampler", through being equipped with the control unit, built-in motor and built-in sampling pump in the main casing internal cavity, can hand-hold the manual sampling, also can place and sample with the ground automatically, automatic shutdown, made things convenient for the on-the-spot sampling work, but the efficiency is low if being used for well-flushing work.
The applicant's utility model patent ZL 201820339278.5 "a special well-flushing sampling pump of novel groundwater environment monitoring well" has solved certain problem, nevertheless has following problem: 1. the automatic water taking and stopping are realized by adopting the water surface sensor, and the idle time still exists after the sampling pump leaves the water surface; 2. the battery bin is unreasonable in structure, the battery and the pump body are sealed and integrated, the battery cannot be replaced, and wiring is complex; 3. the flow of the water pump is not adjustable, and the operability is poor; 4. the diaphragm material of the water pump has influence on water quality and has secondary pollution.
