[detailed description of the invention]
For the ease of understanding the present invention, below with reference to relevant drawings, the present invention is described more fully.Preferred embodiment of the present invention is given in accompanying drawing.But the present invention can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present invention more comprehensively thorough.
It should be noted that, when element is called as " being fixed on " another element, directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may there is centering elements simultaneously.Term as used herein " vertical ", " level ", "left", "right" and similar statement are just for illustrative purposes.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present invention understand usually.The object of term used in the description of the invention herein just in order to describe specific embodiment, is not intended to be restriction the present invention.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Refer to Fig. 1 to Fig. 3, the overturning-preventing warning device 101 of one embodiment of the present invention, comprise overturning-preventing gauge tap 100 and warning light 200.Overturning-preventing gauge tap 100 is for controlling warning light 200.Overturning-preventing gauge tap 100 comprises Angle ambiguity case 110, upper conducting ring 120, lower conducting ring 130 and conducting sphere 140.
Angle ambiguity case 110 is for controlling angle of inclination.Angle ambiguity case 110 comprises upper casing 111 and lower casing 113, and upper casing 111 has a upper shed (figure does not mark), and lower casing 113 has a under shed (figure does not mark).Upper shed is corresponding with under shed to be connected, and jointly forms an accommodating cavity 115 to make upper casing 111 and lower casing 113.Lower casing 113 comprises the sloped sidewall 113a of a ring-type, and sloped sidewall 113a surrounds under shed.
The inwall of upper casing 111d is located at by upper conducting ring 120, and arranges near upper shed.Upper conducting ring 120 is circulus, and around upper shed one week.Upper conducting ring 120 is provided with the upper external conductive electrode 121 for being electrically connected with wire.Specifically in the illustrated embodiment in which, upper casing 111 is taper shape, pyramid or elliptic conic shape, and upper conducting ring 120 corresponds to the circulus of circle, polygon or oval ring.Conducting sphere 140 can roll in upper casing 111, and can be rolled between upper conducting ring 120 and lower conducting ring 130 along sloped sidewall 113a, is conducted by upper conducting ring 120 with lower conducting ring 130.The inwall angle of inclination of upper casing 111 and the inwall angle of inclination of lower casing 113 similar and different.
In other embodiments, upper casing 111 is truncated cone-shaped, prismatic table shape or elliptical table shape, and the diapire size of upper casing 111 is less than upper shed size.Upper conducting ring 120 corresponds to the circulus of circle, polygon or oval ring.Conducting sphere 140 can roll in upper casing 111, and can be rolled between upper conducting ring 120 and lower conducting ring 130 along sloped sidewall 113a, is conducted by upper conducting ring 120 with lower conducting ring 130.The madial wall angle of inclination of upper casing 111 and the madial wall angle of inclination of lower casing 113 similar and different.
When the inwall angle of inclination of upper casing 111 is different with the inwall angle of inclination of lower casing 113, overturning-preventing gauge tap 100 is made to have two different maximum tilt angles, so that be directed to different angle of inclination requirements, optionally upper casing 111 or lower casing 113 are installed as the bottom of Angle ambiguity case 110, thus make overturning-preventing gauge tap 100 scope of application wider.
When the inwall angle of inclination of upper casing 111 is identical with the inwall angle of inclination of lower casing 113, upper casing 111 and lower casing 113 all can be installed as the bottom of Angle ambiguity case 110, thus can not do over again because of setup error.Further, when wall friction is comparatively serious in one of them for upper casing 111 and lower casing 113, oppositely can installs and exchange another and use, thus extending the service life of overturning-preventing gauge tap 100.

In other embodiments, lower casing 113 is truncated cone-shaped, prismatic table shape or elliptical table shape, and the diapire size of lower casing 113 is less than under shed size, and lower conducting ring 130 corresponds to the circulus of circle, polygon or oval ring.Because lower casing 113 has the bottom of a planar shaped, conducting sphere 140 can be rolled a period of time in the bottom of lower casing 113 rolling before sloped sidewall 113a, thus there is certain buffer time, avoid overturning-preventing gauge tap 100 to start warning light 200 when being subject to unexpected, of short duration external impacts.
Further, lower external conductive electrode 131 is for being vertical at second cylinder in the outside of lower conducting ring 130, and lower casing 113 is provided with the second installing hole passed for the second cylinder.
Conducting sphere 140 is housed in accommodating cavity 115.Conducting sphere 140 can roll in lower casing 113, and can be rolled between upper conducting ring 120 and lower conducting ring 130 along sloped sidewall 113a, is conducted by upper conducting ring 120 with lower conducting ring 130.Wherein, the angle of sloped sidewall 113a and horizontal plane is maximum tilt angle, and when the angle that overturning-preventing gauge tap 100 tilts exceedes maximum tilt angle, conducting sphere 140 is rolled between conducting ring 120 and lower conducting ring 130.
Specifically in the illustrated embodiment in which, conducting sphere 140 is metal ball, and is spheroidal.Certainly, in other embodiments, conducting sphere 140 also can be other materials, such as, conducting sphere 140 can be plastic sphere, and the surface of this plastic sphere is coated with one deck conductive layer, because the material of plastics is lighter, be convenient to conducting sphere 140 roll, thus improve the sensitivity of overturning-preventing gauge tap 100.In addition, in other embodiments, conducting sphere 140 can be the shape such as elliposoidal, regular polygon spheroid.
Further, overturning-preventing gauge tap 100 also comprises shell 150, shell 150 comprises the drain pan 153 that top shell 151 removably connects with top shell 151, top shell 151 and drain pan 153 all have an opening, upper casing 111 is positioned at top shell 151, and be fixedly connected with top shell 151, lower casing 113 is positioned at drain pan 153, and is fixedly connected with drain pan 153.When the open butt joint of the opening of top shell 151 and drain pan 153, upper casing 111 and lower casing 113 are spliced into Angle ambiguity case 110.
Specifically in the illustrated embodiment in which, the open outer side of top shell 151 is provided with multiple spaced first mounting lug 151a, the open outer side of drain pan 153 is provided with multiple interval and arranges and multiple second mounting lug 153a corresponding with multiple first mounting lug 151a respectively, first mounting lug 151a and the second mounting lug 153a all offers a through hole passed for threaded fasteners, threaded fasteners passes the through hole of the first mounting lug 151a through hole and the second mounting lug 153a, top shell 151 and drain pan 153 to be removably connected.
Warning light 200 is for sounding the alarm and alarm light.One of them of warning light 200 and lower external conductive electrode 131 and upper external conductive electrode 121 is electrically connected, the another one of lower external conductive electrode 131 and upper external conductive electrode 121 is electrically connected with external power source 300, so that overturning-preventing gauge tap 100 and warning light 200 and external power source 300 are formed series circuit.Wherein, when the angle that overturning-preventing gauge tap 100 tilts exceedes maximum tilt angle, warning light 200 lights and sounds the alarm.
