[0045] Specific implementation mode two: combination figure 1 and Figure 10 Describe this embodiment, a kind of sludge crushing and excavating mechanism used for hydropower station tail water dredging in this embodiment includes a sliding knife bar 55, a knife bar seat 56 and a telescopic device 57, and the knife bar seat 56 is connected by a knife bar seat connecting pin 58 Rotation is installed on the central disc 53, the inner end of the sliding knife bar 55 is installed in the knife bar seat 56, and the outer end of the sliding knife bar 55 is equipped with a stirring knife 59, and one end of the telescopic device 57 is connected by the connecting pin 3 On the outer wall of the knife bar seat 56, the other end of the telescopic device 57 is connected with the pin seat 572 through the telescopic device connection pin 571, and the pin seat 572 is fixedly installed on the inner mounting plate 52; the telescopic device 57 includes an outer telescopic sleeve 573 and the inner...

specific Embodiment approach 3

[0046] Specific implementation mode three: combination figure 1 and Figure 10 Describe this embodiment mode, a kind of sludge crushing and excavating mechanism used for hydropower station tail water dredging in this embodiment mode, the sliding pin 576 is installed on the edge of the outer telescopic sleeve 573, and the nut is connected to the sliding pin 576. A groove is opened on the outer wall of the inner telescopic sleeve 574 along its generatrix, and the end of the sliding pin 576 passes through the outer telescopic sleeve 573 to slide in the groove. In this way, the sliding pin 576 drives the outer telescopic sleeve 573 to slide in the groove of the inner telescopic sleeve 574 , reducing the rotational movement between the outer telescopic sleeve 573 and the inner telescopic sleeve 574 and increasing the service life of the telescopic device 57 .

Abstract

The invention discloses a silt breaking and excavating mechanism for hydropower station tail water desilting, and belongs to the technical field of water conservancy and hydropower devices. The problem of hydropower station tail water silt accumulation is to be solved. The silt breaking and excavating mechanism comprises a sliding cutter bar, a cutter bar seat and a telescopic device. The cutter bar seat is rotatably installed on a central disc through a cutter bar seat connection pin. The inner end of the sliding cutter bar is installed in the cutter bar seat. The outer end of the sliding cutter bar is provided with a stirring cutter. One end of the telescopic device is connected to the outer wall of the cutter bar seat though a connection pin. The other end of the telescopic device is connected with a pin seat through a telescopic device connection pin. The pin seat is fixedly installed on an inner installation plate. The telescopic device comprises an outer telescopic sleeve and aninner telescopic sleeve. The outer telescopic sleeve is slidably installed on the outer side of the inner telescopic sleeve in a sleeving mode. Telescopic springs are installed in the telescopic device. The two ends of each telescopic spring are connected to the outer telescopic sleeve and the inner telescopic sleeve correspondingly. According to the silt breaking and excavating mechanism for hydropower station tail water desilting, deposited sediments underwater can be stirred and suspended.

Description

technical field [0001] The invention relates to a sludge crushing and excavating mechanism used for tail water dredging of a hydropower station, and belongs to the technical field of water conservancy and hydropower equipment. Background technique [0002] After the completion of the hydropower station, the downstream channel of the dam area has experienced many times of flood discharge, washing and digging damage, and the influence of various hydraulic structures and terrain will cause a large amount of siltation in the tailrace channel and the downstream channel, thereby increasing the power generation capacity. The tailwater level affects the output of the unit. In view of these situations, strengthening the management of the tail water dredging project is of great significance for controlling the tail water level of power generation and improving the efficiency of power generation. [0003] The implementation of the excavation project for the tail water of the hydropowe...
