Description
Technical Field
The invention belongs to a dirt cleaning device for cleaning dirt on a trash rack by a water inlet of a hydraulic turbine of a hydropower station or a water inlet of a pump station, and also belongs to a dirt cleaning device matched with a dirt cleaner or other mechanical equipment.
Background
The water inlet of the hydraulic turbine of the hydropower station is generally provided with the trash rack, in order to ensure smooth water flow of the trash rack, the trash attached to the trash rack bottom and the trash rack surface in front of the trash rack needs to be removed, so that the trash rack is prevented from being blocked by the trash rack, head loss is avoided, the safety of the trash rack is endangered in serious cases, and the trash removal by using the trash removal grab bucket is a common method. Generally, the larger the inserting force of the teeth of the trash removal grab bucket into the dirt is, the better the trash removal effect is. In the prior art, for loose dirt attached to the surface, bottom and surface of the trash rack, the dirt removing grab bucket can insert the dirt by means of the bucket tooth insertion force generated by self weight to grab the loose dirt, but for the dirt fixed in front of the trash rack, the bottom and surface of the trash rack, the dirt removing grab bucket is difficult to grab, because the fixed dirt is accumulated under the impact force of the flowing water flow or for a long time at the bottom to form firm fixed dirt, the fixed dirt is difficult to insert by the small bucket tooth insertion force of the dirt removing grab bucket, so the fixed dirt cannot be grabbed, and the fixed dirt causes large head loss to influence the power generation capacity, and the safe operation of the trash rack is seriously influenced along with the increase of the fixed dirt. The common method for solving the problem in the prior art is to increase the weight of the trash-cleaning grab bucket so as to increase the insertion force of the teeth of the trash-cleaning grab bucket. However, after the weight of the trash-cleaning grab bucket is increased, the lifting force of the trash-cleaning machine needs to be correspondingly increased, and meanwhile, the weight of the trash-cleaning machine is greatly increased, so that the investment of the engineering is also greatly increased.

Detailed Description
Fig. 1 is a front view and a side view of a prior art trash-cleaning grab, which mainly comprises a grab frame 1, a rotary rake driving system 2, a guiding device 3, a rotary rake 4 and grab teeth 5. The rotary rake claw driving system 2 mainly comprises a hydraulic pump station, a hydraulic oil cylinder and a hydraulic pipeline. When the trash removal grab bucket descends along the trash rack surface to clean trash rack dirt, the grab bucket teeth 5 can be inserted into the dirt in front of the trash rack, then the rotary rake claws 4 are closed under the driving of the rotary rake claw driving system, and the dirt in front of the trash rack can be grabbed. However, when the dirt in front of the trash rack is solidified, the shovel teeth 5 of the grab bucket are difficult to insert into the dirt in front of the trash rack, and the closed rotary rake 4 cannot grab the dirt in front of the trash rack. And the consolidated dirt which is pushed against the lower part of the bucket tooth 5 seriously hinders the trash removal grab bucket to continue to descend along the trash rack for trash removal, so that the trash removal grab bucket cannot carry out trash removal work.
Fig. 2 is a schematic structural view of an embodiment of the trash cleaning grab bucket capable of breaking consolidated dirt on the trash rack. The trash cleaning grab bucket mainly comprises a grab bucket frame 1, a rotary rake claw driving system 2, a guide device 3, a rotary rake claw 4, a grab bucket tooth 5, a pickaxe 6 and a pickaxe driving mechanism 7. Wherein the pickaxe drill driving mechanism 7 is a hydraulic impactor, and the impact pickaxe drill 6 does reciprocating impact vibration motion. In the scheme, the pickaxe drill rod 6 is not only a pickaxe drill rod for impact crushing, but also a bucket tooth of the grab bucket, and is an integrated scheme of the bucket tooth and the pickaxe drill rod. This grab bucket of decontaminating when carrying out the operation of decontaminating, when trash rack consolidation filth top is in the grab bucket lower part, can carry out reciprocal impact vibration motion through the 7 drive pickaxe borer 6 of pickaxe borer actuating mechanism of dress on the rotary harrow frame, to top the consolidation filth of grab bucket lower part carry out breakage and loose, make the grab bucket of decontaminating can snatch these consolidation filths. Fig. 3 is a schematic view of a pick structure according to the first embodiment, in which 7 is a pick driving mechanism, and 6 is a pick. As can be seen from the figure, the pick 6 is a cylindrical structure with a conical head.
Fig. 4 is a schematic structural diagram of a second embodiment of the trash cleaning grab bucket capable of breaking consolidated dirt on the trash rack. The trash cleaning grab bucket mainly comprises a grab bucket frame 1, a rotary rake claw driving system 2, a guide device 3, a rotary rake claw 4, a grab bucket tooth 5, a pickaxe 6 and a pickaxe driving mechanism 7. Wherein the pickaxe driving mechanism 7 is a waterproof electric impactor, and the impact pickaxe 6 does reciprocating impact vibration motion. In the scheme, a pickaxe drill 6 and a pickaxe drill driving mechanism 7 are connected with a rake frame of the rotary rake grab 4 through a support, and the scheme is a split scheme of bucket teeth and pickaxe drill. This grab bucket of decontaminating when carrying out the operation of decontaminating, when trash rack consolidation filth top is in the grab bucket lower part, can carry out reciprocal impact vibration motion through the 7 drive pickaxe borer 6 of pickaxe borer actuating mechanism of dress on the rotary harrow frame, to top the consolidation filth of grab bucket lower part carry out breakage and loose, make the grab bucket of decontaminating can snatch these consolidation filths. Fig. 5 is a schematic view of a pick structure according to the first embodiment, in which 7 is a pick driving mechanism, and 6 is a pick. As can be seen from the figure, the pick 6 is of a flat steel structure with a flat head.
The invention utilizes the pick drill rod which moves back and forth to crush and loosen the consolidated dirt which is consolidated at the front and the bottom of the trash rack and attached to the surface of the trash rack, so that the self weight of the grab bucket is not increased to increase the insertion force of bucket teeth to grab the consolidated dirt. Therefore, the invention has wide practical application.
