Description

Technical Field

[0001] The utility model belongs to the technical field of cooling towers, and in particular relates to a silt-clearing robot for a water collecting pool of a cooling tower in a power plant. Background Art

[0002] Hyperbolic cooling towers are widely used in power plants. A water collection pool is set at the bottom of the hyperbolic cooling tower. The water collection pool is used to collect and store cooling water. It also plays the role of diverting and distributing cooling water, which plays a very important role in the normal operation of the cooling tower. The water collection pool at the bottom of the hyperbolic cooling tower will form a large amount of silt and other debris after a period of use. These sediments are harmful to the normal operation of the cooling tower, so the hyperbolic cooling tower needs to regularly desilt the water collection pool at the bottom. At present, when desilting the water collection pool at the bottom of the hyperbolic cooling tower, you can choose to use a desilting robot to desilt. While improving the desilting efficiency, the desilting robot can also desilt without stopping the machine. When desilting, the desilting robot mainly uses the silt suction pipe fixed on the remote control vehicle body to suck the silt at the bottom of the water collection pool to the outside of the water collection pool for dehydration and drying. When the current dredging robot is performing dredging work in the sump, if the water depth of the sump at the bottom of the hyperbolic cooling tower is deep, the camera on the dredging robot may be submerged or the camera may extend too low above the water surface, causing great inconvenience to the remote control dredging operation and greatly restricting the use of the dredging robot. In addition, there are many columns in the sump at the bottom of the hyperbolic cooling tower, and accurate observation is required at all times when remotely controlling the dredging robot to avoid collision between the dredging robot and the columns. Summary of the invention

[0003] The utility model aims to provide a dredging robot for a cooling tower sump of a power plant, so as to overcome the defect of a low camera height in the dredging robot for dredging cooling towers of power plants in the prior art.
