Below in conjunction with accompanying drawing, the utility model is illustrated.
The structural representation of Fig. 1 under to be the utility model be in the lock state for the first alarming device 10 of the device of alarm manhole well lid dislocation;
Fig. 2 is that the utility model is for the structural representation of the second alarming device 20 of the device of alarm manhole well lid dislocation;
In figure, the corresponding relation of Reference numeral and each device element is: 1 well lid; 2 boreholes wall; 3 spring struts; 4 steel discs; 5 spring strut fixtures; 6 springs; 7 first warning balls; 10 first alarming devices; 11 rubber bands; 12 second warning balls; 13 containers; 14 apertures; 20 second alarming devices; Wherein Reference numeral 3-7 refers to the utility model for the building block of the first alarming device 10 of the device of alarm manhole well lid dislocation; 11-14 is that the utility model is for the building block of the second alarming device 20 of the device of alarm manhole well lid dislocation.
The specific embodiment
As shown in Figure 1, for the device of alarm manhole well lid dislocation, it comprises the first alarming device 10 and the second alarming device 20.Wherein the first alarming device 10 comprises spring strut 3, steel disc 4, spring strut fixture 5, spring 6 and the first warning ball 7, wherein, spring 6 is arranged in spring strut 3, and its bottom is fixed on the bottom of spring strut 3, its top is fixed on the bottom of this first warning ball 7, the sidepiece of this spring strut 3 is provided with spring strut fixture 5, for this spring strut 3 being fixed to the borehole wall 2 of well head; And this first warning ball 7 is provided with horizontal through hole, the top of spring strut 3 is provided with lock hole; When pressing the first warning ball 7 holddown springs 6 and make through hole on the first warning ball 7 and lock hole on spring strut 3 aligns, steel disc can be locked in spring strut 3 the first warning ball 7 through lock hole and through hole; Then, cover well lid 1, the other end of steel disc 4 is outside well lid 1; At outer this other end by steel disc 4 of well lid 1, be pulled outwardly, when by after steel disc 4 pull-off spring cylinders 3, the locking of the first warning ball 7 will be unlocked.Spring in this spring strut 12 makes the first warning ball 7 upwards arrive the bottom surface of well lid 1 in top thereupon popping up a small part, thereby makes this first warning ball 7 releases.Now, this alarming device is standby, if having dislocation generation, the first warning ball 7 will be effectively ejectedly and and play warning function.
The second alarming device 20 comprises the container 13 of many rubber bands 11, a plurality of the second warning ball 12 and accommodating the plurality of the second warning ball 12, wherein, one end of every rubber band 11 is fixed on this container 13, the other end is fixed on one second warning ball 12, and the density of this second warning ball 12 is less than the density of water.
Wherein, because rainwater often can drain to container 13 from well lid or the borehole wall; for the accelerated ageing of avoiding rubber band 11 to be often immersed in water and to cause; and being provided with in bottom and/or the bottom of described container 13 aperture 14 that a plurality of permission rainwater flow out, the diameter of the plurality of aperture is less than the diameter of this second warning ball 12 so that the second warning ball can not spill from the aperture 14 of container 13.
Described the second warning ball 12 preferably adopts plastic material to make.More preferably, this second warning ball 1 external surface coating reflectorized material and/or fluorescent material are to strengthen pedestrian's recognition effect.The shape of described container 13 can be set to square tube or circular or other any shape of being convenient to processing.
Rubber band 11 preferably position be high-tension rubber band, preferably can meet to be pulled away from well head 1m and to grow and can not rupture.This is because pedestrian or vehicle can not advanced conventionally in darker water.
Wherein, described spring strut fixture 5 can be any common fixed structure, and the simplest form of structure is fixed screw.
The diameter of spring strut 3 does not need too large, with 5-10cm, is advisable, and be too greatly difficult for to eject, and too little being difficult for discovered by pedestrian or vehicle; And when the diameter of spring strut is too large, can descend well operations to produce dirt impact normally on workman.
The top of the first warning ball 7 is spherical, can effectively reduce like this side-friction between the first warning ball and well lid 1, effectively prevent the first warning ball 7 along the direction of well lid 1 translation eject rather than to directly over ejection.
Steel disc 4 is equivalent to a kind of locking part, and the length of steel disc 4 will guarantee after well lid 1 is covered, and stays sufficient length so that steel disc is extracted out and realized release outside well lid 1.Because the regular maintenance of well need to, steel disc 4 may need often to rub with through hole and lock hole aperture, therefore the location optimization in these two holes adopts high-abrasive material to make, for example the through hole place of spring strut and spring strut is all made of metal, and the through hole place of the first warning ball and the first warning ball all has wear-resistant plastic to make.
For the first warning ball 7, its height that ejects ground is at least and is greater than 8cm, is preferably greater than 20cm, is further preferably greater than 30cm.On the first warning ball 7, can be coated with fluorescent material and/or reflectorized material is set, with noticeable.For example, preferred mode can be that this first warning ball 7 is spheroidal, on its ball surface, reflective tape and fluorescent belt is set off and on.The top of the first warning ball 7 should adopt smooth material or coating hard smooth material to make, and when preventing that well lid from moving horizontally, larger frictional force is warned first after ejection the translation direction of the deflection well lid of ball.Meanwhile, it is large to float be also favourable that the buoyancy of the first warning ball 7 in water can be tried one's best.For guaranteeing enough large buoyancy, further can improve and can be: the diameter setting of the through hole of the first warning ball is less, and adopt as far as possible hollow structure in the first warning ball 7.
The first alarming device and the second alarming device are preferably fixed together, and are more conducive to like this integrated of this device for alarm manhole well lid dislocation, the common installation of being also more convenient for.For example, the second alarming device 20 also can be set to tubular, this second alarming device of tubular and the spring strut of the first alarming device are welded together side by side.Like this, only fix the first alarming device, also realized the fixing of the second alarming device simultaneously.
Those skilled in the art can determine the number of the utility model device that every mouthful of well is installed according to actual needs, for the well lid that is provided with rotation fixed axis for one end, because its dislocation mode generally only shows as well lid opened with certain angle rather than well lid translation, therefore this type well lid generally only needs a device of the present utility model, it should be arranged on the offside well head wall of this rotation fixed axis conventionally.For common without fixed structure well lid for, no matter this well lid is square or circular, generally need to more than 4 devices of the present utility model, the so effectively dislocation of alarm manhole well lid be evenly set along well lid marginal position.
Although the example utilizing preferred embodiment has below only been described,, the given specific embodiment of the utility model is that Spirit Essence of the present utility model is described, rather than limits for the scope that it is asked for protection.In the situation that do not depart from spirit of the present utility model and the protection domain being limited by appended claim; those skilled in the art can carry out various distortion and improvement to the utility model, and these distortion and improvement also should be subject to the protection of the utility model patent.
