Abstract
The invention relates to a theftproof protection cap for a fuel tank truck manhole cover, and belongs to the technical field of special vehicles. The protection cap comprises a base which is fixed at the periphery of a manhole to form a surrounding stop and an upper cover which is covered on the base, wherein at least one hinge hole is formed in one side of the base, and a locking bolt is hinged to the other side of the base; a hinge pin hole is formed in the part of the upper cover, which corresponds to the hinge hole; a locking gap is formed in the part of the upper cover, which corresponds to the locking bolt; a hollow hinge pin is fixed in the hinge pin hole, and forms a hinge pair together with the hinge hole; plugs are fixedly inserted at two ends of the hinge pin; mounting stages which are deflected from the axis of the hinge pin and positioned on the same plane are arranged on the inner sides of the two plugs; and a circuit board with a motion sensor is fixed on each mounting stage, and is digitally communicated with an external monitoring device. According to the theftproof protection cap, the sensor is ingeniously arranged in a pin shaft, so that the theftproof protection cap has a simple and rational structure, is convenient to mount, is stable and reliable, and is difficult to attack and damage; furthermore, the protection cap is arranged on the conventional fuel tank truck, and all the functions of the conventional facilities on the truck are retained, so that the theftproof protection cap is practical and feasible.
Description
Technical field
The present invention relates to a kind of theft-prevention structure of truck tanker, especially a kind of truck tanker manhole cover anti-theft protection cover belongs to the special-use vehicle technical field.
Background technology
Manhole cover is one of the key role that can emit on the truck tanker jar interior oil plant.Unless the destruction vehicle structure, opening the manhole cover oil pumping is the common method of emitting jar interior oil plant.For antitheft, take the lead sealing safety method usually.Facts have proved that this antitheft behave actual effect is unsatisfactory.
Retrieval is found, application number is the anti-theft security detecting device that the Chinese patent application of CN201020100734.4 discloses a kind of fuel tank, the clip that comprises the preparation of metal or corrosion-resistant steel, clip is connected and composed by two semi-rings, one coupling end of two semi-rings is provided with hinge, second coupling end of two semi-rings is to open closed keyed end, contact switch or proximity transducer are installed in position in keyed end or two semi-ring closures, the clip fixed oil tank lid that two semi-rings constitute, the oil filling port cervical fixation of the bottom of clip and fuel tank is opened the closed-lock end lock is housed.The sensor and connection mode thereof in fact do not possess anti-theft capability, and are not suitable for the manhole cover of truck tanker.
Summary of the invention
The technical problem to be solved in the present invention is: the shortcoming at above-mentioned prior art exists proposes a kind of can laying the foundation and safe failure-free truck tanker manhole cover anti-theft protection cover for real time monitoring.
In order to solve above technical matters, guard against theft oil tank car manhole cover of the present invention comprises being fixed on and forms the base of enclosing around the manhole and cover loam cake on base; One side of described base has at least one place pan, and opposite side is hinged with lock bolt; Described loam cake has the hinge pin hole corresponding to the pan place, and corresponding lock bolt place has locking notch; Fix the hollow hinge pin that forms hinges with pan in the described hinge pin hole, fixedly plug is inserted at the two ends of described hinge pin respectively, the inboard of described two plugs has the hinge pin of departing from axis and is in conplane installation step, described installation step is fixed with and contains the motion sensor circuit card of (acceleration pick-up is used for monitoring angle speed and displacement), and described circuit card is connected with the communication of exterior monitoring device.
Like this, when needs are opened the manhole cover of truck tanker, must open protective case earlier; and when opening protective case, certainly will order about the bearing pin rotation, thereby make motion sensor send signal to outside monitor unit; make the supervision personnel know that manhole cover is unlocked, take corresponding anti-theft measure in case of necessity.In addition, the data of preservation can be consulted, as evidence.
Because the present invention is arranged in the bearing pin sensor is ingenious, therefore not only simple and reasonable, easy for installation, and also safe reliable, be difficult to be attacked and destroy.And protective case can be attached on original truck tanker, and the repertoire of existing facility is all kept on the car, and is therefore practical.

The specific embodiment
Embodiment one
The guard against theft oil tank car manhole cover of present embodiment such as Fig. 1 comprise base 1 and loam cake 2 to shown in Figure 5.Base 1 has the through hole 1-1 that matches with manhole as shown in Figure 1, and the upper overturning 1-2 that is centered around the border.One side of base 1 has the two pan 1-3 of place, and two socket 1-4 of opposite side are hinged with the lock bolt (not shown) respectively.During installation, base is fixed on the manhole place of truck tanker, and flange 1-2 forms the enclosing of manhole.
Be used to cover on base 1 loam cake 2 as shown in Figure 2, its shape and base 1 match, the border has the following flange 2-1 relative with base upper overturning 1-2.Loam cake 2 has a pair of hinge pin hole 2-2 corresponding to each pan place, and corresponding lock bolt place has locking notch 2-3.After the assembling, snap in coaxial pan between every couple of hinge pin hole 2-2
1-3, insert hollow hinge pin 3 in the hole.This hinge pin and hinge pin hole 2-2 close fit interfix, with pan
1-3Running-fit forms hinges, and therefore as shown in Figure 3, Figure 4, loam cake 2 can rotate and close, opens relative to base 1 around the hinge pin axle.When loam cake 2 was closed, the following flange 2-1 of its border and the upper overturning 1-2 of base 1 were involutory.
The concrete structure of hollow hinge pin 3 as shown in Figure 5, fixedly plug 3-6 is inserted at two ends respectively, the inboard of two plug 3-6 has the hinge pin of departing from axis and is in conplane installation step, be fixed with the circuit card 3-3 that contains acceleration pick-up by screw 3-5 on the installation step, one of plug 3-6 has line outlet 3-2, circuit card 3-3 be connected with the digital communication of exterior monitoring device by the CAN bus conductor that passes line outlet 3-2.Cavity in the hollow bearing pin 3 is filled sealing 3-4, makes circuit card non-dismountable.
Because hinge inner core sensor installation, and sensor waters with epoxy resin with the hinge fuse and is enclosed in, and therefore it can't be separated.And the method for adopt removing hinge is opened manhole cover, must mobile hinge or as the bearing pin of inner core, certainly will cause the change of acceleration due to gravity, and angle measurement data is sent corresponding alerting signal thereupon changing.And as long as to be the CAN bus carry out sensor and outside data communication communicating interrupt, no matter be short circuit, open circuit and all interrupt communication immediately, all will be sent alerting signal, and therefore almost any method all can not be reported to the police in shielding.
Present embodiment is attached to the manhole place of truck tanker, does not influence the original function of manhole cover.Adopt after the present embodiment, can realize real time monitoring, in time know the operational circumstances of manhole cover manhole cover on the truck tanker.It is simple in structure, practical, and sensor is installed hidden, firm, and communication is reliable.
In addition to the implementation, the present invention can also have other embodiments.For example, have the wireless transmission device that sensor signal is sent on the circuit card, thereby be connected with the wireless telecommunications of exterior monitoring device, when loam cake 2 was closed for another example, the following flange 2-1 of its border also can be chimeric with the upper overturning 1-2 of base 1.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
