Abstract

A narrow well life net is formed by weaving the rescue rope into rectangular lumpish net pieces which are a littler greater than the human body; the net pieces are connected with a lifting rope; upper net holes on the net pieces can extend into the arm of the human body and lower net holes can extend to the leg of the human body; two corners on the upper end of the net piece are connected with two main lifting ropes respectively while the lower end thereof is connected with a secondary lifting rope; elastic support rods are fixed to the upper and lower end edges of the net piece; a heavy drop is fixed to the secondary lifting rope; when someone falls into the deep well which can only accommodate one person, the rescuer will drop the net pieces in front of the well falling people who only needs to stretch the arms and legs into the net holes, and then the rescuer can rescue the well falling people by pulling the lifting rope up so as to reach the purpose of conveniently and rapidly saving people.

Description

Narrow well life net

Technical field

The utility model relates to a kind of safety apparatus, and specifically a kind of rescue falls into less and deep-well personnel's the instrument again of bore.

Background technology

In the northern area of China, the peasant is for drought resisting, in the farmland or in the field of farmland periphery, take the method for digging well to get water to water crops, this well often bore is little, can only hold about the people, and deep, because this well does not often have perisotomice again, many well heads are covered by weeds, therefore it is of common occurrence Ren Luojing being arranged, and goes to rescue before the TV news back warp often sees the fire fighter, especially rescues the flurried personnel of those grown-ups and childrens and mind, after the rescue rigging goes down, they do not know how to tie group, can not go to help him on same plane because well head is too little again after the rescuer goes into the well, have to be by loud explanation many times, group pricks reluctantly, if group pricks wrong or bundle group is unreal, the danger of falling down is arranged again in the lifting process, waste is sued and laboured the time.

Summary of the invention

Be unfamiliar with the defective of bundle group for those grown-ups and childrens and the flurried personnel of mind in order to overcome down-hole lifesaving rigging, the utility model provides a kind of narrow well life net, this life net need not specialty bundle group technology, as long as arm and leg are stretched in the mesh, aboveground rescuer just can rescue the personnel to fall into well by ropes.

The utility model solves the technical measures that its technical problem takes, with one of lifesaving rope braiding commonly used a little more than with the rectangle net sheet of being wider than human body, net sheet upper end connects two main ropes respectively for two jiaos, the lower end connects a secondary rope, secondary rope bifurcated near the net sheet time is connected on two jiaos of net sheet, fixedly flexible and rubber-like support bar respectively on the sideline of net sheet upper and lower side, its effect is can strut the net sheet when the down-hole falls, main rope is separately fixed at the two jiaos of directionality that can control the net sheet in upper end, the crotch of secondary rope is installed heavily and is weighed down, its effect is to utilize gravity seine sheet submerged at the net sheet during near the water surface, is convenient to the personnel that rescued near the net sheet.Execute when asking the secondary rope of net sheet is being descended, main rope is transferred rapidly last, when being rescued personnel near quilt, again slowly toward transferring to the dead ahead of being rescued personnel, and guide its arm and leg to stretch in the mesh with literal or the method for propagandaing directed to communicate, the sagging promptly nettle of arm, aboveground rescuer suitably mentions main rope, after affirmation is rescued personnel's arm and leg and is stretched in the mesh, with secondary rope around to by the person's of rescuing behind, promote synchronously main rope and secondary rope, just can with the personnel to fall into well fast, safety rescues, thereby reaches falling into the purpose that narrow well personnel conveniently sue and labour fast.

The beneficial effects of the utility model are to provide a kind of handled easily, salvage tool simple in structure for rescue falls into narrow well personnel.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of narrow well life net.

Among the figure, 1, the net sheet, 2, main rope, 3, support bar, 4, pay and carry, 5, heavily weigh down.

The specific embodiment

In Fig. 1, be woven into the rectangle net sheet 1 that is slightly larger than human body with the lifesaving rope, the mesh on top can stretch into arm, the mesh of bottom can stretch into the thigh of human body, connecting rope is distinguished as main rope 2 for two jiaos in upper end at the net sheet, bifurcated connects on two jiaos of the lower ends of net sheet when paying rope 4 near the net sheet, heavily weigh down 5 and be fixed on the crotch of paying rope, support bar 3 usefulness elastomeric materials are made retractable shaft-like, be fixed in the last lower edge of net sheet, purpose is to strut the net sheet, is convenient to the personnel to fall into well arm and leg are stretched in the mesh, and it is to control the direction of net sheet that main rope divides two purpose; Heavily the effect of Zhuiing is an energy drawn net sheet submerged; Support bar can stretch according to the size of well head, opens in well with maximum area.

Claims

1. narrow well life net, be woven into the block net sheet of the rectangle that is slightly larger than human body with the lifesaving rope, it is characterized in that: net sheet top mesh can stretch into the arm of human body, the bottom mesh can stretch into the thigh of human body, the upper end of net sheet connects two main ropes respectively for two jiaos, lower end auxiliary connection rope, the upper and lower side edge of net sheet be fixing rubber-like support bar respectively, fixingly on the secondary rope heavily weighs down.

2. narrow well life net according to claim 1 is characterized in that: secondary rope connects two jiaos of net sheet lower ends respectively near net sheet time-divisions two fork, in the fixing heavily bob of crotch.

3. narrow well life net according to claim 1, it is characterized in that: support bar is made the telescopic joint shape, can stretch according to the well head diameter.

4. according to the described narrow well life net of claim 1-2, it is characterized in that: the outer surface parcel flexible material that heavily weighs down.
