Abstract

A burglarproof well head equipment comprises a base and a well cover, and is technically characterized in that the base comprises a cylinder made by a cast iron; a skirt rim extending outwards is arranged on a bottom side of the cylinder; a boss extending inwards is arranged on the bottom side of the cylinder; an annular groove is arranged on an upper end surface of the boss. A damping rubber washer is arranged in the annular groove; the well cover comprises the cylinder with an opening on an upper end and a bottom surface on a lower end; a bitumen, a pebble or a concrete is poured in the cylinder; and a plurality of drain pipes are prepared in the cylinder; the lower ends of a plurality of drain pipes are connected with the bottom surface of the cylinder fixedly; a plurality of water outlet holes corresponding to the lower end ports of the drain pipes are arranged on the bottom surface of the cylinder. An external diameter of the cylinder of the well cover is suitable to an internal diameter of the cylinder of the base. The well cover can be arranged into the cylinder of the base and laid on the washer arranged on the boss on the bottom side of the base; a top surface of the well cover is just arranged on an upper end port of the cylinder of the base. The utility model is difficult to lose and has the good buffering and damping effects; thereby a large impact is not produced between the well cover and the base so as to play a role in rolling-proof.

Description

The Pithead preventing thieves device

(1) technical field

The utility model relates to a kind of wellhead assembly, is meant pedestal and well lid that land drainage uses especially.

(2) background technology

Smooth, clean and tidy, unimpeded road is one of important symbol of modern city, also is the important behave of national economy high speed development.Since the reform and opening-up, though our urban construction has obtained developing by leaps and bounds of attracting people's attention, it is traditional by castiron well lid and pedestal that the wellhead assembly on the road remains.There are many problems in this wellhead assembly, first cost height, easily loses, and uses that easily rust is dead for a long time, have to smash well lid in order to open well lid sometimes; It two is easily to cause the injures and deaths serious accident, because well lid is to be made by cast iron, adding does not have anti-theft device, is easy to be stolen by stealer sell, and makes the well head place become a cavity, and pedestrian and vehicle are easy to fall down; It three is that shock resistance is poor, is subjected to after the intense impact easily broken; It four is that vehicle was pressed easily to produce and beated and noise, even can be subjected to displacement or overturn, thus the time malignant event generation that jeopardizes vehicle and pedestrains safety arranged.

(3) summary of the invention

In order to solve the problem that above-mentioned prior art exists, it is strong to the invention provides a kind of wide accommodation, resistance to compression and shock resistance, long service life, low cost of manufacture, convenient, the difficult Pithead preventing thieves device of losing of being stolen of replacing.

The technical scheme that adopts is:

The Pithead preventing thieves device comprises pedestal and well lid, and its technical essential is: pedestal comprises one by castiron cylinder, and the bottom of cylinder has outwards extended the shirt rim, has inwardly extended boss, and the upper surface of boss is provided with annular groove.Be equiped with rubber washer in the ring groove, well lid comprises that a upper end open, lower end have the cylinder of bottom surface, be cast with pitch, stone or concrete in the cylinder, and give and be provided with many gutters, fixedly connected with the bottom surface of cylinder in many gutter lower ends, and be structure as a whole, offer a plurality of on the bottom surface of cylinder and the corresponding weep hole of lower port gutter.The barrel bore size of the outside diameter of cylinder of well lid and pedestal adapts.Well lid can be inserted in the cylinder of pedestal, and sits and crouch on the packing ring that is provided with on the base bottom boss, and the end face of well lid is positioned at the upper port place of pedestal cylinder just.

A plurality of weep holes on the above-mentioned well lid cylinder bottom surface are expand gradually from top to bottom tubaeform.

The intrinsic a plurality of reinforcing ribs of fixedlying connected of the outer wall ring of said base cylinder with the shirt rim of pedestal cylinder bottom.

Antitheft principle

Because the Pithead preventing thieves device adopts seam deep-well lid technology down, if will open well lid, must make well lid keep horizontal vertical upwards could open well lid, if well lid is tilted, not on the position of horizontal vertical, well lid will block, and is difficult to open well lid.Because the thickness of well lid and weight increase.Open well lid to the lawless person and caused certain difficulty.Destroy or the theft well lid if the lawless person adopts, owing to be provided with rubber washer between well lid and the pedestal, external force is had the effect of buffering and vibration damping, can reduce the rupture factor of well lid.In addition, because the increase of well lid thickness, make the hole base lengthening of leaking hole on the well lid, collude the bottom that can't enter well lid with long iron, well lid can't be opened, have only colluding for a short time of employing and leaking hole equal diameters, could collude iron and extend into the bottom, shaft bottom, but the lower end of leaking hole is three times a tubaeform delivery port of leaking hole diameter, little iron is colluded skid off well lid automatically after stressed, has played anti-effect of colluding.

Well lid of the present utility model is owing to be to adopt pitch or cement concrete to make, rather than adopts single cast iron to make, thereby is difficult for losing, and can play antitheft effect indirectly, and then can avoid well lid to lose and serious accident takes place.Moreover, because the thickness of well lid increases, not only can play antitheft effect, also avoided simultaneously turning in the spreading because of motor vehicle, cause well lid to damage or displacement, guaranteed the polarization of well lid.In addition, because the polarization of well lid of the present utility model is equipped with rubber washer between well lid of the present utility model and the pedestal, thereby can plays good buffering, damping effect, make between well lid and the pedestal and can not produce big impact, thereby played the anti-effect that rolls.

Fig. 1 is the structural representation of a kind of embodiment of the utility model.Fig. 2 is the vertical view of Fig. 1.

(5) specific embodiment

The Pithead preventing thieves device comprises pedestal 1 and well lid 2, and its technical essential is: pedestal 1 comprises one by castiron cylinder 3, and the bottom of cylinder 3 has outwards extended shirt rim 4, has inwardly extended boss 5, and the upper surface of boss 5 is provided with annular groove 6.Be equiped with rubber washer 7 in the ring groove 6, well lid 2 comprises that a upper end open, lower end have the cylinder 8 of bottom surface, be cast with the pitch identical 9 in the cylinder 8 with ground surface material, and vertically give and be provided with many and be spaced conglobate gutter 10, the reflective font 11 of build-in adularescent on the pitch 9 of well lid 2 end faces.Fixedlying connected with the bottom surface of cylinder 8 in the lower end of many gutters 10, and is structure as a whole, and offers on the bottom surface of cylinder 8 and the corresponding a plurality of weep holes 12 of the lower port of a plurality of gutters 10.Weep hole 12 is expand gradually from top to bottom tubaeform.The cylinder 3 internal diameter sizes of cylinder 8 external diameters of well lid 2 and pedestal adapt.Well lid 2 can be inserted in the cylinder 3 of pedestal 1, and sits and crouch on the rubber washer 7 that is provided with on the pedestal 1 bottom boss 5.

In order to increase the intensity of pedestal 1, the intrinsic a plurality of reinforcing ribs 13 of fixedlying connected of ring on the outer wall of cylinder 3 with the shirt rim 4 of cylinder 3 bottoms.
