Submersible dredging vehicle

Abstract

A submersible dredging vehicle relates to an underwater dredging technology. The submersible dredging vehicle is provided with a vehicle body, wherein a submersible sewage pump is arranged on the vehicle body, a drain pipe is arranged on a liquid outlet of the submersible sewage pump, four spiral propeller type driving wheels are arranged on the two sides of the vehicle body, spiral directions of the adjacent two driving wheels are opposite, a water retaining cover plate is arranged on the vehicle body, the vehicle body is provided with four driving motors connected with the four driving wheels and is further provided with a water storehouse and a draining pump, the draining pump is provided with a check pump, the water storehouse is provided with a water inlet pipe and a gas identification rod, an electric valve is arranged on the water inlet pipe, and the electric valve, the submersible sewage pump and the four driving motors are connected with a controller. The submersible dredging vehicle can move forwards and backwards, carry out translation, turn around by taking any one driving wheel as a circle center and by taking the center of the vehicle body as the circle center, move and the like through the turning matching of the four driving wheels. The submersible dredging vehicle disclosed by the invention has the advantages of high locomotive maneuverability, simplicity and convenience in position change, easy handling, no dead corner during working, more thorough cleaning, high dredging efficiency and strong subsidence and sliding capabilities.

Description

technical field [0001] The invention relates to underwater dredging technology, in particular to a submersible dredging vehicle used for cleaning the dirt in ponds, pools or sediment pools. Background technique [0002] We know that after a period of use of ponds and pools, there will be a lot of dirt that needs to be cleaned up, especially the sewage pools and sediment pools of various enterprises and factories. After a certain period of use, they need to be cleaned up in time. The existing cleaning methods are usually the following two: one is to manually or mechanically remove the underwater dirt after draining the water in the pool. This method has a large workload, time-consuming and laborious, and wastes water resources and high cost. Another method is to use an underwater desilting machine for cleaning. The structure of the desilting machine is: a dual-power electric vehicle, which is driven by a chain transmission, and one end of the vehicle body is equipped with a ...

Problems solved by technology

The existing cleaning methods are usually the following two: one is to manually or mechanically remove the underwater dirt after draining the water in the pool. This method has a large workload, time-consuming and labor-intensive waste of water resources and high cost

Another method is to use an underwater desilting machine for cleaning. The structure of the desilting machine is: a dual-power electric vehicle, which is driven by a chain transmission, and a submersible sewage pump is installed at one end of the vehicle body. It is equipped with a sewage pipe; this kind of underwater dredging vehicle has the following disadvantages: 1. The vehicle body can only turn when cleaning the sewage at the bottom and cannot move in translation, leaving dead corners that cannot be cleaned, especially when working in a square pool. , poor maneuverability

2. The adhesion of the locomotive cannot be adjusted, the anti-sinking ability is poor, and it is easy to slip

3. It cannot be suspended on the water surface and in the water for cleaning operations

4. A single water pump is fixed in the middle, the dredging cannot reach the side, and the work efficiency is low

5. The size of the whole machine is large, and the remaining dead angle is large
