Technical Field

The invention belongs to the technical field of manufacturing of water cutting rescue protective devices, and particularly relates to a waterproof cutting flexible guard plate.

Background

In the water cutting emergency rescue operation, the situation that people, important property or dangerous goods are behind a cut object and cannot be cut is frequently encountered, because the cutting jet flow still has high energy within a certain distance from the nozzle, particularly when a thick plate is cut, in order to ensure that the cut-off obstacle is cut, the water jet flow moving slowly stays for more time at the cut-off position which is cut through, and meanwhile, due to the characteristic of water cutting, the cut-off prevention plate partition plate can only be made thick when the water cutting is required to be prevented from being cut through at present. If the device is used for on-site rescue, due to the limitation of space, a protective partition plate is difficult to be additionally arranged between the cut object and the protected object. This problem also affects the popularity of water cutting rescue techniques.

Boron carbide materials are very cost effective from the standpoint of hardness and manufacturing cost. A high hardness material is desirable as a protective sheet against cutting. The production method of the boron carbide material mostly adopts a sintering and infiltration method, and boron carbide particles in the material obtained by the existing preparation method can hardly be formed.

Disclosure of Invention

The invention provides a waterproof cutting flexible guard plate, which designs the component units of the guard plate into a mutual clamping connection, and when the guard plate is impacted by particles with high kinetic energy, the particles can not directly pass through the guard plate. And the anti-cutting sheets can rotate at an angle, so that the protection plate formed by the anti-cutting sheets clamped with each other has flexibility of being bent at a certain angle. The cutting tool has the advantages that the cutting tool is wearable, and can be conveniently placed between a cut object and a protected object under the condition of a complex space, so that cutting is realized, and the object which does not need to be cut is protected from being damaged. Even if a small amount of water mixed with an abrasive penetrates through the gaps between the cut-off preventing pieces, as shown in fig. 5, since the water mixed with an abrasive penetrates through the cut-off preventing pieces with the outer walls thereof being blocked, the energy of the movement thereof is lost, and the water mixed with an abrasive penetrating through the shielding plate is not destructive any more.

Fig. 4 and 5 show water mixed with abrasive material 01 and water cut-proof flexible guard board 02.
