Embodiment
As shown in Figure 1, the present invention includes casing, above-mentioned casing comprise chamber door 1, be positioned at the back up pad 2 of chamber door 1 both sides, with the vertically disposed base plate 3 of back up pad 2.Then at box inside, the i.e. back up pad 2 of both sides and base plate 3 surface attachment sound-absorbing material layer 101, described sound-absorbing material layer 101 is three dimensional network structure system, the length-diameter ratio L/D of its grid is between 20 to 30, and namely the length-diameter ratio of grid can be any one ratio in 20,22,25,28,30.
Set temperature sensor 102 and humidity sensor 103 on base plate 3, the temperature signal that temperature sensor 102 and humidity sensor 103 gather and moisture signal are sent in control system 104 respectively, the signal value received and the threshold value preset are compared by control system 104, if temperature signal value is higher than the threshold value preset, then output action signal is to temperature-reducing humidifier structure 106; If moisture signal value is higher than the threshold value preset, then output action signal is to the wet down mechanism 105 that heats.The above-mentioned wet down mechanism 105 that heats can adopt electrical heating vaporation-type mechanism, and above-mentioned temperature-reducing humidifier structure 106 can adopt the humidifier of average family, and these are technology well known to those of ordinary skill in the art.
In anti theft design, between chamber door 1 of the present invention and the back up pad 2 in left side, embedded hinge is adopted to be connected.Chamber door 1 is provided with key code tapered end 5, has anti-drilling, the major function such as pick-proof, anti-skilled unlocking, can prevent the illegal unlatching of chamber door and self-locking mechanism.Above-mentioned key code tapered end 5 is technology well known to those of ordinary skill in the art.In addition, chamber door 1 can also be provided with observation panel 4, for observing the reading of internal electric energy table.The back up pad 2 of chamber door 1 both sides is equipped with radiator window 6, for the loose hot gas except box house.Box house, electric energy meter 7 is suspended on round bar 10, and electric energy meter 7 is provided with handle, for by electric energy meter 7 push-and-pull up or down, combines the below that patching panel is positioned at electric energy meter 7.
As shown in Figure 3, Figure 4, supported on both sides plate 2 is equipped with cambered way, is provided with left chain wheel 10 in left cambered way 8, be provided with right pulley 11 in right cambered way 9, two, left and right pulley is connected by round bar 12, and round bar 12 and movable top cover 17 weld together.Like this, the motion of round bar 10 is driven by the motion of pulley.The middle part of round bar 10 is fixedly connected with drive link 13, left end and the left connecting link 14 of drive link 13 are hinged, right-hand member and the right connecting link 15 of drive link 13 are hinged, and left connecting link 14 is hinged with the back up pad in left side, right connecting link 15 is hinged with the back up pad on right side, and above-mentioned hinged place is turning joint, is provided with left air spring 16 in addition at the middle part of left connecting link 14, left air spring 14 one end and left connecting link 14 hinged, its other end be hinged on left side back up pad 2 on; Be provided with right air spring 17 in the middle part of right connecting link 15, right air spring 17 one end and right connecting link 15 hinged, its other end is hinged in the back up pad 2 on right side, and left and right air spring is used for alleviating the dynamics of slideway and from the bottom to top stroke from top to bottom.
Principle of work of the present invention is: when needing maintenance electric energy meter 7, the handle upwardly electric energy meter 7 arranged, thus round bar 10 is moved upward.Because round bar 10 is fixedly connected with movable top cover 18, therefore in the process moved upward at round bar 10, movable top cover 18 is also opened thereupon.On the other hand, round bar 10 is also fixedly connected with drive link 13, thus drives drive link 13 to move upward, and makes drive link 13 be lifted to upright position by horizontal level.Thus, the travel path of round bar 10 and drive link 13 is circular arc, so be circular arc slideway at the slideway of back up pad 2 both sides.Simultaneously due to the existence of left and right air spring, certain buffer action is had when pulling round bar 10, effectively prevent the strenuous vibration to electric energy meter and the destruction of bringing, in addition, air spring also can play certain supporting role when round bar 10 moves to ways-end.When round bar 10 moves to ways-end, the electric energy meter 7 hung on round bar 10 is also drawn out ammeter box, and now electric energy meter 7 electric wire below also comes out, and staff can overhaul electric energy meter 7.After maintenance, promote drive link 13 and electric energy meter 7 is pushed back to origin-location.After pushing back origin-location, electric energy meter 7 and combined connection box thereof electric wire is below hidden in ammeter box inside, forms self-locking, is also no longer exposed to outside, thus reaches anti-electricity-theft object when opening chamber door 1.
