Description
Technical field
The utility model relates to the chain detection field of rotary sieve, relates in particular to rotary sieve chain length detection field.
Background technology
Rotary sieve is the important component part in the water circulation system of power house, is used for filtering the impurity of the water that enters water circulation system, guarantees the normal operation of water circulation system.The web plate of rotary sieve is installed between the chain of two parallel motions, at the continuous low-speed running of vertical direction.Chain movement need to turn round during to top and bottom, and can rub this moment in the junction of chain link; Along with the accumulation of friction, chain pitch can be increasing, affects the stable operation of rotary sieve, may cause filter screen to damage when serious, and the river of filtered directly enters the power house water circulation system, and major accident occurs.
At present, the elongated problem of pitch that is caused by the rotary sieve chain wear does not also have effectively preventive means, can only rely on the staff rule of thumb regularly to shut down abrasion condition, the measurement chain total length of detection chain; For guaranteeing the rotary sieve safe operation, sense cycle arranges compactly usually, has so both affected the power station and has runed normally, has also increased staff's labour intensity.
The utility model content
The problem of the normal operation in power station is wasted time and energy, affected to the applicant for the method for above-mentioned existing regular detection chain wear, measurement chain total length; carry out Improvement; a kind of rotary sieve chain length automatic detection device is provided; can detect in real time the total length of the chain of rotary sieve; and when total length surpasses design margin automatic alarm; avoid shutting down and detect the loss that chain brings to the power house, guarantee simultaneously safe operation, the reduction labor strength of rotary sieve.
Technique effect of the present utility model is as follows:
A kind of rotary sieve chain length automatic detection device comprises underwater portion and warning part; Underwater portion comprises the side panel that is fixed in frame and is fixed on U-shaped guide rail on the side panel, and device has the chain of rotary sieve in the described U-shaped guide rail, and a side of U-shaped guide rail has breach; Switch block is articulated on the described side panel, and a side of described switch block is aligned in described breach; The part of reporting to the police comprises the fixed head that is fixed in frame, and travel switch and capable of adjusting support board are installed on the described fixed head from top to bottom; Connecting rod one end is articulated on the described switch block, and the other end is connected with touch panel after passing described back up pad, between described touch panel and the described back up pad stage clip is installed; Rotary sieve turns clockwise, and can oppress described switch block deflection when its chain surpasses design limit, and switch block spurs described connecting rod, and the touch panel of described small end can be stirred described travel switch.
Its further technical scheme is:
Described U-shaped guide rail comprises front gathering sill, lower gathering sill and rear gathering sill successively, gathering sill before described lower gathering sill one end connects, and the other end is positioned at the below of described rear gathering sill, forms breach with rear gathering sill; One side of described switch block is curved, and described arc-shaped side edges is with flange, and described flange is aligned in described breach;
Described connecting rod comprises connecting rod and lower link, and described upper connecting rod and lower link are connected in the sleeve two ends by pin respectively;
Be connected with the adjustment plate on described back up pad and the side that described fixed head engages, offer waist-shaped hole on the described adjustment plate, described back up pad is connected by the bolt in the described waist-shaped hole with described fixed head plate.
The beneficial effects of the utility model are:
Rotary sieve turns clockwise, and switch block is in slack list one side of chain; When the chain total length increased, the chain festival-gathering was swelled in indentation, there, the chain festival-gathering compressing switch block deflection of protuberance, switch block pulling connecting rod; When the total length of chain was increased to certain-length, the chain festival-gathering of protuberance was so that the touch panel of switch block drivening rod upper end is stirred the travel switch on the fixed head, thus automatic alarm.The utility model can be removed the work that regular shutdown detects chain wear from, reduce the power house shutdown loss, alleviate labor strength, can guarantee that again the wear control of rotary sieve chain is in scope of design simultaneously.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Such as Fig. 1 and shown in Figure 5, the utility model comprises underwater portion and warning part.
As shown in Figure 1, underwater portion comprises the side panel 8 that is fixed in frame and is fixed on U-shaped guide rail on the side panel 8, described U-shaped guide rail comprises front gathering sill 1, lower gathering sill 6 and rear gathering sill 16 successively, lower gathering sill 6 is circular arc, the one end is connected in front gathering sill 1, the other end is positioned at the below of described rear gathering sill 16, forms breach 13 with rear gathering sill 16; Device has the chain of rotary sieve in the described U-shaped guide rail, as shown in Figure 2, the pin link plate 5 of adjacent two chain links of described chain and inner plate 7 are articulated in respectively on the bolt 2, and be spacing by latch 3, in the periphery of bolt 2 roller 4 is installed between two inner plates 7, roller 4 slides in described U-shaped guide rail.
Such as Fig. 3 and shown in Figure 1, a side of switch block 11 is arc, and described arc-shaped side edges is with flange 111, and switch block 11 bottoms have the first hinge hole 112, are connected with articulated slab 9 by the first bearing pin 10, and articulated slab 9 is fixed on the side panel 8; It is hinged with connecting rod 14 that the second hinge hole 113 is passed with the second hinge hole 113, the second bearing pins 12 in the top of switch block 11.After being installed on the side panel 8, the flange 111 of switch block 11 is aligned in breach 13, as an ingredient of the capable guide rail of U.
