Abstract
The utility model relates to a water-sealed cable device which is characterized by comprising a metal wall panel, an indoor water storage pipe, an outdoor water storage pipe and an open type support ring, wherein both sides of the metal wall panel which is welded with the wall panel of a workroom for sealing are respectively fixed with the indoor water storage pipe and the outdoor water storage pipe; both the indoor water storage pipe and the outdoor water storage pipe are in an S-shaped structure, and the tail ends abut against each other and are connected to form a U-shaped structure; and the communicated cavities of the indoor water storage pipe and the outdoor water storage pipe are filled with water to form a water-sealed structure. By using such soft material as water to seal the cable based on the U-shaped pipe principle, the utility model realizes the positive pressure of the workroom, thereby preventing dangerous gas from entering the room and avoiding personnel poisoning and natural gas explosion. When the difference between the indoor pressure and the outdoor pressure is 50Pa and the water surface in the outer pipe is 5mm higher, multiple experiments prove that no air leaks, the seal is reliable and the effect is favorable through the actual observation for a cycle of seven days.
Description
Technical field
The utility model belongs to the cable mounting technique, relates in particular to a kind of mobile anti-explosion safety space in places such as oil field, colliery, flammable and pernicious gas and water seal cable unit that its peripheral cables is passed through of being applied to.
Background technology
In the field drilling process, all has natural gas at any time or toxic gas overflows.For guaranteeing job safety, on-the-spot various detecting instruments all adopt the unified installation of skid instrument shelter.In most cases, these complicated instrument and equipments are not explosion-proof, but adopt whole skid instrument shelter carried out explosion-proof processing.Usually adopt the method for positive-pressure explosion-proof, promptly operating room's internal air pressure is greater than external pressure (at least can not less than 50Pa).Because the used type of cable of instrument is various, thickness does not wait, and passes through the cable part and does not possess sealing, and when indoor and outdoor pressure reduction was 50Pa, the outer tube water surface exceeded 5mm, air leaks can occur, and it is unreliable to cause sealing.The industry is demanded thoroughly solving cable urgently and is passed from the positive-pressure explosion-proof instrument shelter, causes the sealing problem of this cable outlet.
The utility model content
The utility model is in order to overcome deficiency of the prior art; A kind of water seal cable unit is provided; Can satisfy the cable fast and reliable that moves anti-explosion safety space and its ancillary equipment in places such as oil field, colliery, flammable and pernicious gas and pass through, thoroughly solve the problem that the cable part does not possess sealing of passing through.
The utility model is for realizing above-mentioned purpose; Realize through following technical scheme; A kind of water seal cable unit; It is characterized in that: comprise Metal wall, indoor standpipe, outdoor standpipe and open type support ring, affixed indoor standpipe and outdoor standpipe are distinguished in said Metal wall both sides with operating room's wallboard welded seal, and said indoor standpipe and outdoor standpipe shape are S shape; Constitute U-shaped after its tail end butt joint links to each other, indoor standpipe that communicates and outdoor standpipe inner chamber inject water and constitute water-stop.
Said Metal wall both sides are connected with the metal interface sleeve of intercommunication, and the tail end of said indoor standpipe and outdoor standpipe is pegged graft with the metal interface sleeve respectively, and indoor standpipe after the grafting and outdoor standpipe outer surface are provided with fastening larynx hoop.
Said indoor standpipe and outdoor standpipe middle and upper part sidewall are connected with hangers respectively; Said hangers hangs on the open type support ring of indoor standpipe and outdoor standpipe middle and upper part, and two openings of said support ring are pegged graft with the affixed fixedly eye-splice in both sides, Metal wall middle and upper part respectively.
Said indoor standpipe and outdoor standpipe top end opening place are provided with and tighten rope.
Beneficial effect: rely on this soft material of U type pipe principle water to come hermetically-sealed cable, thereby realize the malleation operating room, stop in the hazardous gas inlet chamber, the personnel of preventing poison and gas explosion.Through repeatedly experiment, when indoor and outdoor pressure reduction was 50Pa, the outer tube water surface exceeded 5mm, actual observation 7 days, no air leaks, sealing reliably confirms respond well.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a malleation operating room sketch map.
Among the figure: 1, Metal wall, 2-1, indoor standpipe, 2-2, outdoor standpipe, 3, the open type support ring; 4, fastening larynx hoop, 5, the metal interface sleeve, 6, hangers, 7, cable; 8, fixedly eye-splice, 9, tighten rope, 10, cable inlet, 11, the malleation operating room.
Embodiment
Below in conjunction with preferred embodiment; Details are as follows to the embodiment that provides according to the utility model: see accompanying drawing for details; A kind of water seal cable unit; Comprise Metal wall 1, indoor standpipe 2-1, outdoor standpipe 2-2 and open type support ring 3, affixed indoor standpipe and outdoor standpipe are distinguished in said Metal wall both sides with operating room's wallboard welded seal, and said indoor standpipe and outdoor standpipe shape are S shape; Constitute U-shaped after its tail end butt joint links to each other, indoor standpipe that communicates and outdoor standpipe inner chamber inject water and constitute water-stop.Said Metal wall both sides are connected with the metal interface sleeve 5 of intercommunication, and the tail end of said indoor standpipe and outdoor standpipe is pegged graft with the metal interface sleeve respectively, and indoor standpipe after the grafting and outdoor standpipe outer surface are provided with fastening larynx hoop 4.Said indoor standpipe and outdoor standpipe middle and upper part sidewall are connected with hangers 6 respectively; Said hangers hangs on the open type support ring 3 of indoor standpipe and outdoor standpipe middle and upper part, and two openings of said support ring are pegged graft with the affixed fixedly eye-splice 8 in both sides, Metal wall middle and upper part respectively.Said indoor standpipe and outdoor standpipe top end opening place are provided with and tighten rope 9.
Around the Metal wall with operating room's wallboard welded seal; Standpipe is formed injection water in the U type pipe, at a distance from the retaining air, plays the water-stop effect.Standpipe is a kind of transparent visual flexible pipe, is used for estimating the water surface and the water yield, detects sealing condition; The effect of open type support ring is to make two standpipes upwarp about an angle of 90 degrees, forms the U font.Fastening larynx hoop is a kind of clamp, plays further fixing and sealing function; Standpipe is enclosed within on the metal interface sleeve, and the metal interface sleeve is processed into certain slope and reserves groove, seals with standpipe better.
Execution mode
1, puts into this device cable inlet 10 places of malleation operating room 11, to welding between Metal wall and the operating room;
2, except the open type support ring was not installed earlier, remaining part all installed;
3, straight line is worn cable 7;
4, construction opening formula support ring makes inside and outside standpipe upwarp about an angle of 90 degrees;
5, toward the interior water filling of standpipe;
6, outlet pipe is carried out simple and easy sealing with tightening rope, so far accomplished implementation process.
