Description

technical field [0001] The invention relates to a hydrological survey equipment, in particular to an all-electric hydrological survey vehicle. Background technique [0002] With the rapid development of hydrology, hydrological survey technology is playing an increasingly important role in hydrological survey work, and has become one of the important symbols of the transformation from traditional hydrology to modern hydrology. [0003] The continuous development of hydrological survey vehicle technology has promoted the progress of hydrological survey work. Since the 1970s when the combination of hydrological survey and station teams started piloting in my country, hydrological survey vehicles have gradually been popularized and applied in hydrological survey work. The key technology of hydrological survey vehicles - the power take-off method of hydrological winches has experienced a long period of development. The course of development and evolution. [0004] 1. The mode o...

AI Technical Summary

Problems solved by technology

At the same time, problems such as excessively long hydraulic pipelines, hydraulic oil leakage, and high failure rates have always plagued this power take-off mode

However, this power take-off mode has the following problems: (1) The oil pipeline is too long, the energy loss is large, and the hydraulic oil temperature rises due to long-term flow measurement; (2) The mechanical equipment at the front of the car is densely packed, and the space is relatively narrow. The power take-off oil pump has certain technical difficulties; (3), there are many high and low pressure oil pipelines, and the structure of the hydraulic workstation is complex, which may easily cause leakage of the hydraulic system; (4), installation, disassembly, and maintenance are inconvenient

[0009] At present, several hydrological survey (bridge survey) vehicles produced in China are facing the same technical bottleneck: 1. Because the hydrological winch adopts hydraulic drive mode, the problem of hydraulic oil leakage is difficult to solve; There are many parts in the system, the system has high requirements for cleanliness and sealing, and the failure rate is high; 3. The hydraulic transmission efficiency is low and the power loss is large; 4. The hydraulic system has a large self-weight, resulting in too much self-weight of the winch; 5. The safety and reliability of the hoist Problems; 6. Due to many hydraulic oil pipes and oil tanks, the hydrological winch is not easy to disassemble and install; 7. Due to the complicated mechanical structure, it is difficult to attach manual operation devices
