Abstract
The invention discloses a remote automatic locking and unlocking device of a reservoir strobe, comprising a strobe vertical shaft, a strobe body, a locking block and a strobe control system, wherein the strobe control system is used for controlling the strobe; the locking block is also provided with an electric hydraulic mechanism; the locking block and the electric hydraulic mechanism are arranged at both edges of the strobe body; and the strobe control system can control the electric hydraulic mechanism to be put to and retreated from the locking block. The strobe control system controlling the strobe can not only remotely control the lifting of the strobe, but also modify the strobe control system when the remote automatic locking and unlocking device is installed and also remotely control the locking block, thereby removing the limit that a worker is necessary to move for locking in-place without needing the worker to reach a field for the operation of the strobe; and in addition, the remote automatic locking and unlocking device has the advantages of small equipment volume, simple distribution, simple transmission mode, low investment cost and convenient maintenance and is suitable for the condition of insufficient field equipment distribution space.
Description
Technical field
The invention belongs to the Hydraulic and Hydro-Power Engineering technical field, particularly a kind of reservoir strobe remote automatic locking and tripper.
Background technology
The reservoir strobe in domestic each power station all possesses the ability or the potential ability of remote operation at present, and lead to power grid accident, all take manually to drop into the mode of clamping block with gate lock usually because of wire rope or lifting appliance fault cause the gate accident to fall for avoiding when the unit operation.But when increasing safety factor, also caused reservoir or power station emergency occurring need be with closing gate the time, but can not remote operation, personnel must reach the spot and cancel locking, need the regular hour and reach the spot, the loss that can cause the accident easily again this moment enlarges.At present general sluice control system all can be realized the distant place opening and closing operation of gate, and terrain LCU control module inserts control room, a distant place, power station with optical fiber.Though gate itself has possessed the function of remote operation, throw and to move back the restriction that must move by artificial terrain owing to be subjected to the gate lock piece, cause at every turn operation to gate still to need personnel to arrive terrain and carry out.When unit and equipment meet the crisis situation and need fall the closing gate water source immediately, will can't a distant place withdraw from and causality loss is enlarged because of clamping block, cause extra economic loss.
Summary of the invention
The invention provides a kind of automatic throwing and move back the reservoir strobe remote automatic locking and the tripper of gate lock piece.
A kind of reservoir strobe remote automatic locking and tripper, comprise gate vertical shaft, gate body, clamping block and the sluice control system that is used for regulating gate, also be provided with electric hydaulic mechanism on the described clamping block, described clamping block and electric hydaulic mechanism are arranged on gate body both sides, and described sluice control system can be controlled the throwing of electric hydaulic mechanism and move back described clamping block.
The sluice control system of regulating gate of the present invention not only can Long-distance Control to the lifting of gate, and be set the while of the present invention, revise sluice control system, also can carry out Long-distance Control to clamping block, this has just removed the restriction that must be moved locking by artificial terrain, does not need the staff to reach the spot to the operation of gate and operates.When unit and equipment meet the crisis situation and need fall the closing gate water source immediately; directly by sluice control system instruction electric hydaulic mechanism; electric hydaulic mechanism can throw and move back clamping block afterwards, has avoided causality loss expansion, causes extra economic loss.This apparatus features is that equipment volume is little, layout is succinct, is fit to the situation of site plant arrangement space deficiency; The kind of drive is simple, and investment cost is low, is convenient to safeguard.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1 is the structural representation of reservoir strobe remote automatic locking of the present invention and tripper.
The specific embodiment
As shown in Figure 1, a kind of reservoir strobe remote automatic locking and tripper, comprise gate vertical shaft 1, gate body 2, clamping block 3 and the sluice control system that is used for regulating gate, also be provided with electric hydaulic mechanism 4 on the described clamping block 3, described clamping block 3 is arranged on gate body 2 both sides with electric hydaulic mechanism 4, and described sluice control system can be controlled 4 throwings of electric hydaulic mechanism and move back described clamping block 3.
In the gate shaft both sides two small-sized electric hydraulic mechanisms 4 are installed, as the power set of gate lock piece.The clamping block along continuous straight runs moves inside and outside both sides, owing to do not carry any load during the clamping block motion, sliding distance is about 260mm, so lays steel sheet under the schematic design metal locking slide block and can meet the demands to alleviate frictional resistance.
In the gate opening process, consider highly to move smoothly for the clamping block of h (20cm), gate should promote the distance of L=h * (1+50%) more, reserving enough spaces to clamping block puts in place and certain time limit is set in program and wait for and drop into returning of signal, therefore, gate should more than the precalculated position and promotes 30cm.And fall within on the clamping block for the weight of guaranteeing gate after the clamping block input rather than bear by wire rope, program is provided with the clamping stroke of 2cm, and the 12cm that promptly falls again fully loosens wire rope.
When gate need be closed, gate upwards promoted earlier the 12cm piece that goes out of lock, to be locked withdraw from and signal returned after, program continues the whereabouts gate to fastening position.
Program is the input of clamping block and withdraws from the longest time limit of setting, if be t the actuation time that actual test clamping block is thrown, pushed away
01 and t
02, then the longest wait t=t actuation time
0+ t
0* 0.8.When PLC when t does not receive the action return information of clamping block in the time, the concurrent alarm signal that is out of order of program shut-down operation notifies the operator on duty in time to check.
Owing to the former clamping block in gate both sides is thrown the mode of moving back for manually pushing and pulling out, its operation needs on-the-spot many people's cooperations to finish, and gate hoisting depth and gate enter the clamping stroke cooperation of latched position and estimate judgement by the Field Force entirely.Therefore, though gate itself has possessed the function that opens and closes automatically,, still need to withdraw from the PLC automatic mode and go forward side by side and just can finish into operate in manual mode because clamping block is thrown the requirement of push operation.
Because the gate lock piece only drops into when the gate opening position, therefore to design when gate rises and should be reserved with enough spaces that clamping block can drop into, after to be locked automatic the input, gate falls within and is in latched position on the clamping block.
When gate need be closed, earlier gate is mentioned the certain altitude piece that goes out of lock, to be locked drop to fastening position downwards after withdrawing from again.Significantly shorten reservoir strobe and close preceding locking post-set time, improve the safety factor of Hydropower Unit hydraulic facilities.
