Desilting device for hydraulic engineering

Abstract

The invention discloses a desilting device for hydraulic engineering. The desilting device comprises support frames, a connecting mechanism and a desilting box. The two support frames are fixedly connected with each other through the connecting mechanism. The desilting box is arranged above the connecting mechanism. A water pumping pipe is arranged on one side of the desilting box, and the other side of the desilting box is provided with a water discharging pipe. Air cylinders are arranged on the side, far away from the desilting box, of the water pumping pipe and the side, far away from the desilting box, of the water discharging pipe. A support plate is arranged below the air cylinders. Support pillars are arranged at the four corners of the support plate, and a stirrer is arranged at the middle position of the support plate. The connection and separation of position limiting holes and position limiting pins can realize the position adjusting function of an outer connecting member and an inner connecting member, namely, the function of free adjustment of the length of the connecting mechanism is realized, so that the desilting operation for hydraulic engineering with a variety ofwidths is adapted, and the applicability is wide.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a dredging device for water conservancy engineering. Background technique [0002] In the process of my country's economic development, water conservancy projects have played an extremely important role. It can not only realize the reasonable allocation of my country's scarce water conservancy resources, but also promote the harmonious development of ecological resources. It also plays an important role in ecological maintenance. However, due to the different climate and environment every year, and with the increase of the service life of water conservancy projects, siltation often occurs at the bottom of reservoirs and lakes. Although it is a natural phenomenon, it has a negative impact on the utilization efficiency of water conservancy projects. Therefore, dredging of water conservancy projects has become very necessary.

[0002] In the process of my country's economic development, water conservancy projects have played an extremely important role. It can not only realize the reasonable allocation of my country's scarce water conservancy resources, but also promote the harmonious development of ecological resources. It also plays an important role in ecological maintenance. However, due to the different climate and environment every year, and with the increase of the service life of water conservancy projects, siltation often occurs at the bottom of reservoirs and lakes. Although it is a natural phenomenon, it has a negative impact on the utilization efficiency of water conservancy projects. Therefore, dredging of water conservancy projects has become very necessary. Although the production technology of existing dredging devices is becoming more and more sophisticated, it is still There are some deficiencies to be improved

[0003] The dredging device for water conservancy projects in the prior art has the following problems: 1. The existing dredging device partly uses a suction pipe, a filter device and a water suction pipe to cooperate with the operation to clean up the silt at the bottom of the water conservancy project. Although the dredging effect is good, but the In order to get a better extraction effect, the pumping pipes often directly contact the bottom, which is easy to destroy the biological communities (including plants, animals, microorganisms and their germplasm resources, etc.) on the bottom surface of the dredging operation area; 2. The current dredging device Most of the silt at the bottom of the river is absorbed by the silt pump, but more water is also absorbed during the adsorption process. The mixing of water and silt makes subsequent silt cleaning more difficult and increases the labor intensity of operators.
