Description
Technical Field
The invention relates to the technical field of flowmeter supports, in particular to a split inspection well flowmeter support and a use method thereof.
Background
With the continuous development of urban progress, more and more people live and work in the cities, so that the management requirements on the cities are higher, and in terms of the most basic domestic sewage treatment, one city is required to treat millions of tons of domestic sewage every day, and the information such as sewage flow, liquid level, flow rate and the like at all places is required to be monitored and counted on line in real time according to the development of the cities and the requirements of informationized construction. A Chinese sewage pipe network is characterized in that well chambers exist, the shapes of the well chambers are different, and the sizes of the well chambers, the sizes of the overhaul wellhead and the sizes of the sewage pipes are different. This results in no direct access to the interior of the sewage intake conduit from the manhole wellhead. The effect of flowmeter support is under the condition that can't descend the inspection shaft bottom, can't get into sewage inlet tube, puts into the assigned position with the flowmeter probe to guarantee that the flowmeter is firm and has not vibrated, can take out the equipment of clearance flowmeter probe when needing again. The accurate measurement difficulty of sewage flow is great, takes the Doppler ultrasonic flowmeter which uses more at present as an example, and the flowmeter probe can be often blocked by winding of floaters, dirt, garbage, sediment and the like in sewage, so that the measurement is inaccurate, and the flowmeter probe needs to be cleaned periodically and irregularly.
The flowmeter bracket is particularly important as a support frame for supporting the flowmeter probe, and the flowmeter bracket used in the market at present is basically an integrated and permanently fixed bracket, which is quite heavy and difficult to disassemble. Because the probe is arranged in a sewage inlet pipeline of several meters or even more than ten meters under the ground, a large amount of toxic and harmful flammable and explosive gases such as hydrogen sulfide, methane, carbon monoxide and the like can be accumulated in the inspection well. Therefore, before cleaning the probe, special vehicle pulling ventilation equipment is needed to be used, long-time ventilation is carried out on the inspection well in advance, the concentration of harmful gas is monitored in real time, only after the concentration of the gas is within a safety range, people can be dispatched to go into the well to detach the bolts, the flowmeter bracket is taken out, and ventilation on the inspection well is kept all the time during the well descending. There are great potential safety hazards and the use and installation are complicated.
The personnel in the well need to tie up the safety belt, and simultaneously, another one to two people need to tightly pull the safety rope on the ground of the well mouth so as to prevent toxic gas from suddenly overflowing under water or to timely pull up the personnel in the well when other unexpected accidents occur. However, the human body cannot bear too large impact force, so that the speed of pulling the safety rope cannot be too high, the personnel lift the well too long, and the gas such as hydrogen sulfide can be deadly in a small amount of short time, so that the safety of the personnel descending the well cannot be ensured even if the safety belt exists.
In the next step, even if no safety accident occurs, the underground operation space is very limited and cannot be performed in the inspection well with the depth of about 10 meters and the diameter of less than 0.7 meter. The underground is provided with a backboard, a bracket, an escalator, a tool and the like, which are easy to hurt operators.
At present, the traditional bracket used in the market has the weight of more than one hundred jin after the whole bracket is filled with water, and two to three people are required to work cooperatively at the same time to barely pull out the whole bracket. The length of the integrated support is generally 5-10 m, the wellhead is very narrow, the inclination angle of the support is very small, the support is basically straight upwards and downwards when taken out, and the arm length, the moment and the lifting are very laborious. And the support with the length of about 10 meters is directly upwards and downwards, so that the support is easy to touch nearby high-voltage lines, buildings, vehicles and pedestrians. Thus, at least five to six professionals are needed for cleaning the probe every time, the personnel cost is high, and the working intensity of the staff is increased.
When the traditional flowmeter bracket is used, if the water level in the inspection well is deeper and exceeds the water level depth when the bracket is installed, if the water submerges the fixing bolts of the bracket, the water can be discharged only by a professional with a diver's certificate when the bolts are screwed and disassembled and the whole bracket is lifted. Meanwhile, ventilation is needed all the time before and during the well descending operation, the electrifying problem of ventilation equipment is needed to be solved on site, a generator is either provided, or a power supply is needed to be found nearby, the ventilation equipment is used in negotiation with a power property unit, professional certification electrician wiring operation is needed, and the professional level requirement on staff is high.
When the traditional support is used, if the probe needs to be cleaned, the bolts are required to be disassembled in the pit, and the probe and the whole support are taken out. After the cleaning is finished, the probe and the bracket are put back into the inspection well, and the bolts are screwed down again. If the liquid level is high, the diver needs to be supported to go into the well, or only individual bolts above the liquid level are fixed, but the support is not fixed firmly, and the vibration is large, so that measurement is inaccurate. Moreover, each time the probe is cleaned, the cleaning cost is very high, and the total cost of personnel and equipment is about two thousands to three thousands of yuan. To ensure accuracy of flow measurement, the probe is cleaned once in about two months, and therefore, each probe is cleaned only at a very high cost each year.
In summary, from the viewpoints of safety, working labor intensity, personnel occupation cost, professional witness using, and time consumption for cleaning the probe, and from the viewpoint of cleaning cost, a novel sewage inspection well flowmeter bracket is urgently needed. The utility model has the advantages of it need not artifical operation of going into the well, need not even take out the flowmeter support is whole, just can easily clear up the flowmeter probe on inspection shaft mouth ground, thoroughly solve the potential safety hazard when flowmeter probe is clear up big, intensity of labour is big, the occupation number is many, need to be equipped with professional support staff, clear up the long time of consumption, clear up the high difficult problem of expense.
