Abstract
The utility model relates to a kind of suspension type dirt cleaning machine that can regulate upper-lower position according to water level, its agent structure is common rotary type trash cleaning device, the rear of trash rake is fixing trashrack, described trash rake is suspended to the below of a Hoisting System, Hoisting System is fixed on basis, the both sides of described trash rake arrange and are slidably matched, and this is slidably matched and is limited in a slideway base, and trash rake entirety under the manipulation of Hoisting System can be slided up and down along this slideway.The design's structure is simple, reliable operation, and relative to thick old heavy traditional structure trashrack, greatly can save cost of manufacture, efficiency of simultaneously removing contamination improves greatly, thoroughly solves many power stations in technical background and cannot use the situation of rotary type trash cleaning device.
Description
Technical field
The present invention relates to a kind of rotary type trash cleaning device, be specially the suspension type dirt cleaning machine that can regulate upper-lower position according to water level, be adapted at the use in certain circumstances that water level is comparatively dark and SEA LEVEL VARIATION is larger.
Background technology
In the early days of foundation and even to the nineties in last century, domestic large quantities of power station, particularly some at right angle setting height power station of being greater than more than 15 meters, the interception of its dirt is all simply be designed to trashrack, its degree of depth is general very dark, while dirt is difficult to cleaning, trashrack manufacturing specification is very big, seriously cause the wasting of resources, also have impact on the generating efficiency in power station simultaneously, also leave hidden danger to generating set simultaneously, use rotary type trash cleaning device can improve this situation, but because rotary type trash cleaning device is promoted the use of more late, major part power station generally can not cut off the water and the position of reserved trash rake equipment installation, therefore the technological transformation carrying out rotary type trash cleaning device is difficult to implement.
Summary of the invention
The object of this invention is to provide a kind of trash rake of suspended structure moving up and down, this device responds to water level in real time by level sensor, conveniently carry out moving up and down suspension to remove contamination work in the water layer region that amount of contaminants is larger, thoroughly solve the deficiency that prior art exists.
The technical solution adopted in the present invention is: the suspension type dirt cleaning machine that can regulate upper-lower position according to water level, its agent structure is common rotary type trash cleaning device, the rear of trash rake is fixing trashrack, described trash rake is suspended to the below of a Hoisting System, Hoisting System is fixed on basis, the both sides of described trash rake arrange and are slidably matched, and this is slidably matched and is limited in a slideway base, and trash rake entirety under the manipulation of Hoisting System can be slided up and down along this slideway.
Described slideway base adopts steel plate installed-welded to be ∏ type, and be fixed on concrete foundation canal wall by several anchor rib, described trash rake both sides arrange pulley or slide block.
Level sensor is set in trash rake periphery, water level is set at the control unit of Hoisting System and receives change-over circuit, to control lifting or the whereabouts of trash rake.
Described Hoisting System is an elevator and supporting control element.
Arrange Hoisting System by top, trash rake hydrous water level sensor can respond to water level in real time, moves up and down adjustment according to water level by trash rake along slideway base, realizes trash rake and is in optimal working region all the time, thus reaches best effect of removing contamination.
Structure of the present invention is simple, reliable operation, and relative to thick old heavy traditional structure trashrack, greatly can save cost of manufacture, efficiency of simultaneously removing contamination improves greatly, thoroughly solves many power stations in technical background and cannot use the situation of rotary type trash cleaning device.
Accompanying drawing explanation
Accompanying drawing 1 is the integral installation design sketch of trash rake;
Fig. 2 is the trash rake installation region partial enlarged drawing in Fig. 1;
Fig. 3 is embodiment of the present invention top view;
Fig. 4 is the slideway base partial enlarged drawing in Fig. 3.
Wherein: 1. trashrack, 2. slideway base, 3. trash rake, 4. level sensor, 5. Hoisting System.
Detailed description of the invention
Case study on implementation below with regard to some hydropower station (the wide 6m in diversion hole, high 50m) elaborates by reference to the accompanying drawings:
The suspension type dirt cleaning machine of upper-lower position can be regulated according to water level, its agent structure is common rotary type trash cleaning device, the rear of trash rake is fixing trashrack 1, described trash rake both sides arrange and are slidably matched, this is slidably matched and is limited in a slideway base and slides up and down along this slideway, arrange Hoisting System above trash rake, trash rake top suspension is on the suspension hook of this Hoisting System.
Described slideway base adopts steel plate group to defend as ∏ type, and be fixed on concrete foundation canal wall by several anchor rib, described trash rake both sides arrange pulley or slide block.
Level sensor is set in trash rake periphery, water level is set at the control unit of Hoisting System and receives change-over circuit, to control lifting or the whereabouts of trash rake.
For convenience of description, we suppose that basis end elevation absolute altitude is 0m, and its level of dead water absolute altitude 30m, normal pool level 35m, wet season water storage level 42m, flood level 45m, service bridge is 50m.
Former trashrack design height 41.5m, dirt close quarters is 5m below the water surface to the water surface, therefore slideway base design end elevation 25m, i.e. 5m below level of dead water; Design crest level 43m, i.e. 1m above wet season water storage level.After trash rake is installed, can be moved up and down along slideway base by Hoisting System according to the water level height of level sensor transmission is real-time, achieve the maximizing efficiency of cleaning dirt, trash rake design relative altitude is only seven or eight meters simultaneously, also save manufacturing cost greatly, really accomplish low energy consumption large effect.
