Description
Technical field
The utility model relates to a kind of improvement of fast-opening blind safety interlock structure.
Background technique
When fast-opening blind has pressure at its internal tank, do not allow to open, in case open, security incident occurs easily.Existing fast-opening blind, the staff can't determine whether its inside has pressure; And safety interlock is not set; The staff can be normally with its unlatching; This has just brought potential safety hazard.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of simple in structure, with pressure alarm indication, the fast-opening blind safety interlock that can't open when there is pressure inside.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises shell flange, the opening of shell flange is provided with the blind plate skull, one side of blind plate skull is provided with vent hole, be provided with L shaped safe clamp between blind plate skull and shell flange, it is characterized in that: safe clamp corresponds to vent hole and is provided with through hole; One interlock passes through hole and is tightly connected with vent hole; Described interlock comprises the housing that is communicated with vent hole, is provided with inside in housing and has the slideway of piston seal block, is provided with Returnning spring on the piston seal block, and the side of housing is provided with driving hole corresponding to the end of slideway.
, as a kind of preferred version of the present utility model, be provided with range sensor corresponding to the piston seal block on described housing; Range sensor is connected with the explosion-proof control box with tutorial light.
Further, described explosion-proof control box is connected with solar power supply apparatus.
When in container, pressure being arranged, the piston seal block slides into the position of driving hole along slideway under the effect of pressure, dead the driving hole gear, range sensor detects the output signal of piston seal block simultaneously, and teletransmission, to control box, has pressure to exist in the container of tutorial light caution simultaneously, due to piston seal block gear solid wrench hole, interlock is in the lock state, and can't open fast-opening blind, has guaranteed safety.When in container during without pressure, the piston seal block is got back to original state under the effect of Returnning spring, and driving hole exposes, become through hole, while sensor testing signal, teletransmission is to control box, tutorial light sends the with no pressure indication, and can back out interlock with special spanner and open fast-opening blind this moment.
The beneficial effects of the utility model: 1, the utility model is simple in structure, and production and processing is convenient.
2, the piston seal block in the utility model housing is when having pressure, and the piston seal block moves to the slideway end, and driving hole is blocked, and spanner can't stretch in driving hole, so fast-opening blind can't be opened; When there is no pressure in fast-opening blind, the piston seal block leaves driving hole, fast-opening blind could be opened, and is safe and reliable.
3, the utility model is monitored the position of piston seal block constantly by sensor, thereby determines, in fast-opening blind, whether pressure is arranged; Show by tutorial light, be convenient to the staff and constantly grasp the interior situation of fast-opening blind, further improve safety reliability.
4, the utility model is connected by solar power supply apparatus, reaches the purpose of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is the interlock unlatching.
In accompanying drawing, 1 is that blind plate skull, 2 is that vent hole, 3 is that interlock, 4 is that driving hole, 5 is that range sensor, 6 is that piston seal block, 7 is that housing, 8 is that safe clamp, 9 is that shell flange, 10 is that explosion-proof control box, 11 is that power switch, 12 is that tutorial light, 13 is solar power supply apparatus.
Embodiment
The utility model comprises shell flange 9, the opening of shell flange 9 is provided with blind plate skull 1, one side of blind plate skull 1 is provided with vent hole 2, is provided with L shaped safe clamp 8 between blind plate skull 1 and shell flange 9, and safe clamp 8 corresponds to vent hole 2 and is provided with through hole; One interlock 3 passes through hole and is tightly connected with vent hole 2; Described interlock 3 comprises the housing 7 that is communicated with vent hole 2, is provided with inside in housing 7 and has the slideway of piston seal block 6, is provided with Returnning spring on piston seal block 6, and the side of housing 7 is provided with driving hole 4 corresponding to the end of slideway.
, as a kind of preferred version of the present utility model, be provided with range sensor 5 corresponding to piston seal block 6 on described housing 7; Range sensor 5 is connected with the explosion-proof control box 10 with tutorial light 12.
Further, described explosion-proof control box 10 is connected with solar power supply apparatus 13.
Also be provided with power switch 11 on described explosion-proof control box 10.While not using for a long time, power switch 11 can be closed.
Below in conjunction with description of drawings using process of the present utility model: when fast-opening blind is closed, first blind plate skull 1 is closed to the predetermined position of closing, then safe clamp 8 is installed, make the through hole of safe clamp 8 corresponding with the vent hole 2 of blind plate skull 1; The housing of interlock 37 is passed the through hole of safe clamp 8, the special spanner that will match with driving hole 4 inserts in driving hole 4, and rotation interlocking device 3 connects interlock 3 with vent hole 2.Can first carry out sealing in interlock 3 and vent hole 2 joints.Then got final product booste operation.
When there was pressure fast-opening blind inside, pressure was pushed to piston seal block 6 end of housing 7 inner slides, and piston seal block 6 blocks driving hole 4; Simultaneously, range sensor 5 is sensed the position of piston seal block 6, and signal is passed to explosion-proof control box 10, and the tutorial light 12 of explosion-proof control box 10 shows that there is pressure in fast-opening blind inside; At this moment, interlock 3 is in the lock state, and interlock 3 can't unload, and the assurance fast-opening blind can't be opened when pressure is arranged.
When fast-opening blind is opened, when device interior pressure discharges fully, the piston seal block 6 of interlock 3 reclaims, driving hole 4 is open mode, simultaneously, the tutorial light 12 of control box shows pressure-less state, and could unload interlock 3 this moment by driving hole 4, then take off safe clamp 8, open finally fast-opening blind.
Above content is the further description of the utility model being done in conjunction with concrete preferred implementation; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
