Description

Water-soluble release pipe clamp

Technical Field

The invention belongs to the technical field of components of water quality sampling equipment, and relates to a water-soluble release pipe clamp.

Background

With the rapid development of economic society of China, the problem of environmental pollution is more and more prominent, water pollution is one of outstanding pollution problems, the prevention and the protection of water resources are more and more concerned and emphasized by the nation and even the whole society, how to efficiently obtain water quality information is the premise of effectively preventing, treating and solving water pollution, and water quality sampling is the key link for obtaining water quality information. Utilize unmanned aerial vehicle to carry out the water sampling, for traditional artifical sampling and automatic sampling's mode, not only have efficient, with low costs, greatly reduced intensity of labour, the more secure outstanding advantage of staff personal safety, nevertheless to unmanned aerial vehicle use the most outstanding problem promptly alleviate whole fuselage weight and then increase unmanned aerial vehicle's duration.

Disclosure of Invention

In order to overcome the problem that the pump-free water sample collecting device is not provided with a water sample collecting switch, and simultaneously, the purpose of reducing the whole load of the unmanned aerial vehicle as much as possible and further increasing the cruising ability of the unmanned aerial vehicle is achieved, the invention provides the water-soluble release pipe clamp, which utilizes the good water-soluble release pipe clamp with elastic performance and is assisted by the lock pin capable of easily triggering the return clamp, so that the problems can be effectively solved;

in order to achieve the purpose, the technical scheme adopted by the invention is as follows: the utility model provides a water-soluble release pipe strap, lockpin including pipe strap main part and water-soluble material are made, this pipe strap main part includes first press leg and second press leg, the one end of first press leg and the one end elastic connection of second press leg, the other end of first press leg is provided with two second jack catchs side by side, there is the space between two second jack catchs, the other end rigid coupling of second press leg has first jack catch, first jack catch and second jack catch are jagged ring, the opening direction of first jack catch is opposite with the opening direction of second jack catch.

The pipe clamp main body in the water-soluble release pipe clamp is made of metal or nonmetal materials with excellent elastic property, and has good resilience; the lockpin is made of a material with excellent water-solubility performance, and can be quickly dissolved after meeting water, so that the pipe clamp main body can be quickly opened in water, the follow-up work can be quickly unfolded (such as in a pump-free water sample collection device, a sampling bottle can be quickly triggered to start the water sample collection), and the working timeliness is improved. The water-soluble pipe clamp is flexible and convenient, and simultaneously greatly optimizes the complexity of products, and reduces the weight and the production cost of the products.

In the figure: 1. the locking device comprises a locking pin, 2, a first clamping leg, 3, a second clamping leg, 4, a first clamping jaw and 5, a second clamping jaw.

Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in fig. 1, the water-soluble release pipe clamp of the invention comprises a pipe clamp main body and a lock pin 1, wherein the pipe clamp main body comprises a first clamping leg 2 and a second clamping leg 3, one end of the first clamping leg 2 is elastically connected with one end of the second clamping leg 3, two second clamping jaws 5 are arranged at the other end of the first clamping leg 2 side by side, a gap is arranged between the two second clamping jaws 5, a first clamping jaw 4 is fixedly connected at the other end of the second clamping leg 3, the first clamping jaw 4 and the second clamping jaw 5 are both rings with notches, and the opening direction of the first clamping jaw 4 is opposite to that of the second clamping jaw 5.

The first and

second legs

2, 3, which are resiliently connected, form a resilient member.

The pipe clamp main body is made of metal or nonmetal materials with excellent elastic performance, such as elastic plastic and the like.

The lock pin 1 is made of water-soluble materials, has certain hardness and can bear the resilience force of the pipe clamp main body, so that the lock pin 1 can be effectively prevented from being broken by the resilience pressure of the pipe clamp main body before work begins.

When the water-soluble release pipe clamp is used: placing a hose to be clamped between a first clamping leg 2 and a second clamping leg 3, applying opposite pressures on the first clamping leg 2 and the second clamping leg 3, wherein under the action of the pressures, as shown in fig. 2, the free end of the first clamping leg 2 and the free end of the second clamping leg 3 move oppositely and elastically contract until a first clamping jaw 4 enters a gap between two second clamping jaws 5, and the three clamping jaws enclose an annular space, as shown in fig. 3; at this time, the lock pin 1 is inserted into the annular space, and the pipe clamp body is in a resilient state by using the rigidity and hardness of the lock pin 1 itself, as shown in fig. 4. When the clamped hose is placed into water, the water-soluble release pipe clamp is immersed into the water, the lock pin 1 can dissolve in the water, and along with the gradual dissolution of the lock pin 1, the free end of the first clamping leg 2 and the free end of the second clamping leg 3 gradually move in opposite directions under the action of elasticity until the first clamping leg 2 and the second clamping leg 3 are completely opened, and water can enter through the hose.
