The safety mechanism is characterized in that the manhole plate (3) is connected with the cabinet bottom of the outdoor prepackage type transformer station through a hinge (4), the cabinet bottom (1) is hinged to a top rod (5), the inner side of the manhole plate (3) is provided with a groove aperture matching the top rod (5), when the manhole plate (3) is closed, the cabinet bottom (1) is fixedly connected with the manhole plate (3) through a fixing point (2), and when the manhole plate (3) is open, the top rod (5) is inserted into the groove aperture. According to the safety mechanism, the manhole plate is well fixedly connected with the cabinet bottom, even when maintenance is provided under severe weather conditions such as strong wind, the manhole plate cannot be closed by wind, and the safety of the maintenance personnel is guaranteed.
Description
Technical field
The utility model relates to a kind of release mechanism of outdoor preassembled transformer station people inlet hole cover plate, belongs to outdoor preassembled transformer station technical field.
Background technology
Outdoor intelligent preassembled transformer station is a kind of novel power supply corollary equipment.Along with going deep into of China's upgrading urban and rural power grids and construction, need a kind of automation development that meets electrical network intelligent remote image data of design to require, improve the technical support product of power supply reliability, increase city aesthetics, be used for replacing the product of the built on stilts inlet wire of original picture cobweb formula, such design is convenient to approach load center, with this, save electric equipment and cable investment, to realize the technical optimization of electrical power trans mission/distribution system, and there is very strong flexibility and reliability, be applied to the open air intelligence preassembled transformer station of the unified supporting power supply in Residential Areas of Shanghai.Owing to being installed on open air, when installing, overhauling for equipment, personnel's safety has a very high requirement.
People's inlet hole cover plate of existing outdoor preassembled transformer station, the general top that is directly placed on people's inlet hole position of casing, do not carry out extra fixing, when equipment installation, maintainer need to enter people's inlet hole inside, directly people's inlet hole cover plate is removed, this mode people's inlet hole cover plate not being fixed easily causes the loss of people's inlet hole cover plate, and while people's inlet hole cover plate contingency is fallen can pound people, has potential safety hazard.
People's inlet hole cover plate of existing outdoor preassembled transformer station, also have and adopt one end and casing to carry out that hinged mode is fixed, when installation, maintainer need to enter people's inlet hole inside, manually cover plate is pulled open, while overhauling under the inclement weather conditions such as strong wind, people's inlet hole cover plate is easily closed by wind, thereby maintainer's personal safety is threatened.
Summary of the invention
The purpose of this utility model is, a solution is provided, and while making to overhaul under the inclement weather conditions such as strong wind, people's inlet hole cover plate can not closed by wind, thereby can not threaten to maintainer's personal safety.
The utility model is taked following technical scheme:
A release mechanism for outdoor preassembled transformer station people inlet hole cover plate, is connected by hinge 4 at the bottom of the case of described people's inlet hole plate 3 and outdoor preassembled transformer station, and at the bottom of described case, 1 is also hinged with push rod 5, and described people's inlet hole plate 3 inner sides are provided with the slotted eye mating with push rod 5; When people's inlet hole plate 3 is closed, at the bottom of described case, 1 is fixedly connected with by fixing point 2 with people's inlet hole plate 3; When people's inlet hole plate 3 is opened, described push rod 5 inserts described slotted eye.
The feature of the technical program is: by fixing point is set, lock function between realizing at the bottom of people's inlet hole plate and case, simultaneously by the push rod connecing with case bottom hinge is set, when people's inlet hole plate closing, push rod is placed on box house, when people's inlet hole plate is opened, push rod is pivoted, insert in the slotted eye of people's inlet hole plate inner side, withstand people's inlet hole plate, realize the good fixation of people's inlet hole plate.
Further, the diameter of described push rod 5 is 6 to 8 millimeters.
Further, when described push rod 5 inserts described slotted eye, the angle at the bottom of case between horizontal plane and people's inlet hole board plane is 105 °.
The beneficial effects of the utility model are:
1) good fixing between having realized at the bottom of people's inlet hole plate and case.
2) even while overhauling under the inclement weather conditions such as strong wind, people's inlet hole cover plate can not closed by wind yet, thereby can not threaten to maintainer's personal safety.
3) security performance of outdoor preassembled transformer station is promoted greatly.
4) operation that people's inlet hole plate opens and closes is all very convenient, quick, and reliability is high.
Accompanying drawing explanation
Fig. 1 is the vertical view of the release mechanism of the outdoor preassembled transformer station people of the utility model inlet hole plate.
Fig. 2 is the left view of Fig. 1.
Wherein, 1. at the bottom of case, 2. fixing point, 3. people's inlet hole plate, 4. hinge, 5. push rod.
Embodiment
Below in conjunction with specific embodiment, the utility model is further illustrated.
As shown in Figure 1, a kind of release mechanism of Novel outdoor intelligence preassembled transformer station people inlet hole plate, comprise at the bottom of case 1, with hinge 4 and the 1 people's inlet hole cover plate 3 being connected at the bottom of case, at the bottom of people's inlet hole plate 3 and case, 1 homonymy is respectively arranged with fixing point, when people's inlet hole plate is closed, between fixing point, by pin or lockset, be fixedly connected with.
As shown in Figure 2, at the bottom of case, 1 is also hinged with push rod 5, and people's inlet hole plate 3 inner sides are provided with the slotted eye mating with push rod 5;
When keeping in repair or installation personnel need to enter people's inlet hole, first to fixing point release, more upwards pull open people's inlet hole plate with hand, rotate 105 °, push rod is rotated and inserted in the slotted eye of people's inlet hole plate 3 inner sides along hinged place, withstand people's inlet hole plate.
The two ends of push rod 5 are round hook.The diameter of push rod 5 is 6 to 8 millimeters.
Even under the bad weather of strong wind, also can guarantee maintainer's safety like this.
