Description
Technical field
The utility model relates to a kind of electric stormproof louvre, belongs to the manufacturing technology field of ventilation equipment.
Background technology
Electric stormproof louvre is the rainproof ventilation facility that is applied to large-size thermal power plant, nuclear power plant and industrial premises, existing electric stormproof louvre mainly by fixing rainproof blade, can regulate rainproof valve block, framework, with drainage channels body side frame, slip nylon sleeve, nylon turning cylinder, electric operator etc. constitute up and down.But rotation because employing nylon turning cylinder and nylon sleeve slide, the equipment of adding operates in the many especially thermal power plant steam turbine building of coal ash, after operation a period of time, the slip rotating part will rotate ineffective because of entering of coal ash, then can't rotate because of blocking, can't reach effect rainproof and that regulate; It is smooth simple to regulate rainproof valve structure design, can only play simple closing function, lacks the rainproof function of secondary.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively improve the electric stormproof louvre of water-resistant performance.
The utility model is an electric stormproof louvre, comprise the housing that constitutes by up and down framework and body side frame, place the fixing rainproof blade of housing inside and the rainproof valve block of regulating of band turning cylinder, place the electric operator of outer frame bottom, the side that it is characterized in that body side frame is provided with respectively the link gearing that links to each other with turning cylinder one end with electric operator, is provided with totally-enclosed stainless steel ball bearing between turning cylinder and the body side frame.
The described two ends of regulating rainproof valve block can be 90 ° of corner bevelling hook structures, make it to have the rainproof function of secondary.
Described fixing rainproof blade also can be provided with the stainless steel protection network outward.
The utility model compared with prior art has following outstanding advantage and good effect:
1, stormproof louvre opens and closes and rotates flexibly.Totally-enclosed stainless steel ball bearing is set between turning cylinder and body side frame, make dust can't enter the housing inside that constitutes by up and down framework and body side frame, stainless steel can guarantee non-corroding again, can overcome prior art and adopt the nylon material fatal shortcoming of aging distortion with age, thereby ensure the long-term flexible running of equipment.
2, have the rainproof function of secondary, rainproof effect is better.The two ends that can regulate rainproof valve block are 90 ° of corner bevelling hook structures, when tilting to install with angle with the fixing rainproof blade in first road, when making not the wind and rain that is blocked by the fixing rainproof blade in first road get to second road can to regulate on the rainproof valve block, rainwater will be blocked by the valve block of 90 ° of corner bevelling hook structures and drain into the open air once more, has played better rainproof effect; The regulating rainproof valve block and can make and close tightlyer of 90 ° of corner bevelling hook structures simultaneously, inleakage is littler.
3, effectively protection.Air intake surface at fixing rainproof blade is provided with the stainless steel protection network, can effectively prevent in the foreign matter inlet chambers such as worm, bird.
Description of drawings
Fig. 1 is an overall schematic of the present utility model;
Fig. 2 is an A-A face structure cutaway view shown in Figure 1;
Fig. 3 is that B shown in Figure 1 is to structural representation;
Fig. 4 is a structure enlarged diagram of regulating rainproof valve block described in the utility model.
The specific embodiment
The utility model is mainly by the housing that is made of up and down framework 1 and body side frame 2, place the fixing rainproof blade 3 of housing inside and the rainproof valve block 4 of regulating of band turning cylinder 10, place the electric operator 7 of outer frame bottom, the link gearing 6 that places body side frame 2 sides to link to each other with turning cylinder 10 1 ends with electric operator 7 respectively, place the totally-enclosed stainless steel ball bearing 5 between turning cylinder 10 and the body side frame 2, place stainless steel protection network 8 formations such as grade outside the fixing rainproof blade 3.The two ends that can regulate rainproof valve block 4 are 90 ° of corner bevelling hook structures 9.
During use, the utility model is installed in the middle of the skin, connects power supply, can regulate rainproof valve block 4 by electric operator 7 and be adjusted to optimal ventilation and rainproof angle, be generally 45 °-60 °, to guarantee normal draught area.When storm comes interim, will be after rainwater is got on the fixing rainproof blade 3 in band gutter, first road along gutter flow to the body side frame with drainage channels 2 that is connected with two ends, rhone by body side frame is drained rainwater smoothly, and the rainproof valve block 4 of regulating in second road is 90 ° of corner bevelling hook structure designs because of what adopt, when tilting to install, the rainproof valve block of regulating of 90 degree corner bevelling designs just has the rainproof function of secondary, the wind and rain that is blocked by the rainproof blade in first road will not be blocked and discharge the open air once more.Stainless steel protection network 8 can effectively prevent in the foreign matter inlet chambers such as worm, bird.
The utility model is through actual motion, have rainproof effective, rotate flexibly, service life The advantages such as long, easy to maintenance and intelligent automatic control, can be widely used in the thermal power plant, Nuclear power plant, and the rainproof and air inlet system of other industrial premises heating and ventilation project.
