Description
Technical Field
The invention relates to the technical field of a flowmeter bracket, in particular to a split type inspection well flowmeter bracket and a using method thereof.
Background
With the continuous development of city process, more and more people live and work in cities, so the management requirements for cities are higher and higher, and for the most basic domestic sewage treatment, millions of tons of domestic sewage are treated in one city every day. The sewage pipe network in China has the obvious characteristics that the sewage pipe network has well chambers, the shapes of the well chambers are different, and the sizes of the well chambers, the sizes of the well mouths of inspection wells and the sizes of sewage pipes are different. This results in the wellhead of the manhole not reaching the interior of the sewage inlet pipe. The effect of flowmeter support is under the unable inspection shaft bottom of going down, the unable sewage inlet tube's of getting into the condition, puts into the assigned position with the flowmeter probe to guarantee that the flowmeter is firm not have the vibration, can take out the equipment of clearance flowmeter probe again when needing. The sewage flow is difficult to measure accurately, and taking the currently used Doppler ultrasonic flow meter as an example, the flow meter probe is often wound and blocked by floaters, dirt, garbage, silt and the like in the sewage, so that the measurement is inaccurate, and the flow meter probe needs to be cleaned regularly and irregularly.
The flowmeter bracket is particularly important as a support frame for supporting a flowmeter probe, and the flowmeter brackets used in the current market are basically all integrated and permanently fixed brackets, so that the flowmeter bracket is very heavy and is very difficult to disassemble. Because the probe is arranged in a sewage inlet pipeline with a plurality of meters or even more than ten meters underground, a large amount of toxic, harmful, inflammable and explosive gases such as hydrogen sulfide, methane, carbon monoxide and the like can be gathered in the inspection well. Therefore, before cleaning the probe each time, a special vehicle is required to be used for hauling ventilation equipment, the inspection well is ventilated for a long time in advance, the concentration of harmful gas is monitored in real time, only after the concentration of the gas is within a safety range, a person can be dispatched to go into the well to disassemble the bolt, the flowmeter support is taken out, and the ventilation of the inspection well is kept all the time during the going into the well. Has great potential safety hazard and is complex to use and install.
The personnel of going into the well will be in charge of and tie the safety belt, simultaneously, still need another one to two people to tighten the safety rope on well head ground to prevent under water and spill over the toxic gas suddenly, or when taking place other unexpected accidents, can in time pull up the personnel in the well. However, since the human body cannot bear too much impact force, the speed of pulling the safety rope cannot be too high, so that the well-lifting time of personnel is too long, and gas such as hydrogen sulfide can be deadly in a short time in a small amount, so that the safety of personnel going into the well cannot be ensured even if safety belts are arranged.
To put it back, even if no safety accident occurs, in an inspection well with the depth of about 10 meters and the diameter of less than 0.7 meter, the underground operation space is very limited and cannot be developed. And the underground is provided with a back plate, a bracket, a hand staircase, tools and the like, which are easy to damage operating personnel.
At present, in the traditional support used in the market, the whole support is filled with water and then reaches more than one hundred jin, and two or three persons are required to work cooperatively at the same time, so that the whole support can be lifted out reluctantly. The traditional integrated support is generally 5-10 meters in length, the wellhead is narrow, the inclinable angle of the support is small, the support is basically straight up and down when taken out, the arm is long, the moment is large, and the lifting is very laborious. And the bracket with the length of about 10 meters is straight up and down, so that the bracket is easy to touch nearby high-voltage wires, buildings, vehicles and pedestrians. Therefore, at least five to six professionals are needed for cleaning the probe each time, the personnel cost is high, and the working intensity of the workers is increased.
When the traditional flowmeter support is used, if the water level in the inspection well is deep and exceeds the water level depth when the support is installed, the fixing bolts of the support are submerged by water, and when the bolts are unscrewed and the whole support is lifted, a professional with a diver certificate is required to perform water launching operation. Meanwhile, ventilation is required before and during operation in a well, the problem of electrification of ventilation equipment needs to be solved on site, a generator is equipped, or a power supply needs to be found nearby, the power supply needs to be negotiated with a power supply property unit for use, professional certified electrician wiring operation is required, and the requirement on the professional level of workers is high.
When the traditional support is used, if the probe needs to be cleaned, the bolt needs to be disassembled in the well first, and the probe and the whole support are taken out. After cleaning, the probe and the bracket are put back into the inspection well, and then the inspection well is put down to tighten the bolt. If the liquid level is high, it is necessary to prove that the diver is going to work in the well or only fix a single bolt above the liquid level, but then the support fixation is not firm and the vibration is large, resulting in inaccurate measurement. Moreover, each time of cleaning the probe takes several hours to half a day, the cost of cleaning once is very high, and the total cost of personnel and equipment is about two thousand to three thousand yuan. In order to ensure the accuracy of flow measurement, cleaning is basically carried out once in about two months, and according to the calculation, the cleaning cost of each probe is very high each year.
In conclusion, a novel sewage inspection well flowmeter support is urgently needed from the viewpoints of safety, working labor intensity, personnel occupation cost, professional certified personnel use, and probe cleaning time consumption, or from the viewpoint of cleaning cost and expense. The novel inspection well head does not need manual well descending operation, even the whole flow meter support does not need to be taken out, the flow meter probe can be easily cleaned on the ground of the inspection well mouth, and the problems that the potential safety hazard is large, the labor intensity is large, the number of occupied people is large, professional licensees need to be equipped, the cleaning time is long, and the cleaning cost is high when the flow meter probe is cleaned are thoroughly solved.
