Description

Technical Field

[0001] The utility model relates to the technical field of blasting construction, in particular to a water-sealed blasting water bag. Background Art

[0002] Blasting water bags generally refer to water cannon mud bags used in blasting operations. They are substitutes for the earlier traditional latex bubble mud and yellow mud. They have the advantages of good dust prevention, prevention of electric sparks, hygiene and safety, and easy use. They are made by injecting water into a cylindrical polyethylene plastic bag and sealing the mouth. Its length is generally around 250 to 300 mm, and its diameter is slightly smaller than the diameter of the blasthole. The blasting water bag can seal the mouth and, secondly, the water cannon mud explodes at the same time during the explosion, and the water forms mist and is distributed in the air, which can reduce dust, cool down and absorb toxic and harmful gases.

[0003] When the existing blasting water bag is used, it is not easy to fill water into the water bag because the water inlet of the water bag is made of soft plastic. In addition, after the water bag is filled with water, the water inlet is tied with a rope, which can easily cause the water in the water bag to spill out when used. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0027] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0030] Combined with Figure 1-5When the bag is filled with water, the pressure in the water bag body 1 will be greater than the external pressure, so that the sealing plate 4 will be firmly pressed against the water inlet to prevent water from overflowing.

[0031] As a preferred solution of the utility model, the elastic structure includes a fixed block 5, which is fixedly connected to the hard mounting seat 3, and a limited groove is provided on the fixed block 5; a rotating shaft 6, which is fixedly connected to the sealing plate 4; the rotating shaft 6 is rotatably connected to the limited groove of the fixed block 5, and the elastic structure also includes a torsion spring 7, which is sleeved on the rotating shaft 6, one end of the torsion spring 7 is fixedly connected to the fixed block 5, and the other end is fixedly connected to the rotating shaft 6 or the sealing plate 4. When the water bag body 1 is filled with water, the water pressure can be used to conveniently drive the sealing plate 4 to rotate in a counterclockwise arc, and the sealing plate 4 drives the torsion spring 7 to deform when rotating.

[0032] As a preferred solution of the utility model, in order to ensure the sealing effect of the sealing plate 4 on the water inlet, the number of the fixed block 5 and the number of the rotating shaft 6 are both two, and the two rotating shafts 6 are sleeved with a torsion spring 7.

[0033] As a preferred embodiment of the present invention, a wear-resistant layer is provided on the outer surface of the water bag body 1. The material of the existing water bag is relatively thin. When the water bag is filled into the blast hole, it is easy for the protruding stones to scratch the water bag, causing the water in the water bag to flow out, thus causing failure in use. The provision of the wear-resistant layer in this embodiment increases the wear-resistant properties of the water bag body 1. Therefore, after the water bag body 1 is filled with water and placed in the blast hole, the outer surface of the water bag body 1 will not be worn and broken by the protruding stones in the blast hole, thereby causing the water in the water bag body 1 to flow out before blasting, thereby effectively increasing the protection of the water bag body 1 to the internal water.

[0034] As a preferred embodiment of the present invention, the wear-resistant layer includes a polyetheretherketone layer 8 and a polyurethane layer 9. The polyetheretherketone layer 8 is arranged on the outer surface of the water bag body 1, and the polyurethane layer 9 is arranged on the outer surface of the polyetheretherketone layer 8. The thickness of the polyetheretherketone layer 8 and the polyurethane layer 9 are both 1-2 mm.

[0035] As a preferred embodiment of the present invention, a lead 10 and a lead mounting hole 11 are provided on the water bag body 1. The lead 10 is fixed in the lead mounting hole 11 by glue, and the inner wall of the lead mounting hole 11 is provided with a high temperature resistant layer. The high temperature generated by the existing water-sealed blasting water bag when the lead burns will cause the water bag to rupture, and the water inside will directly extinguish the lead, causing the blasting to stop. In this embodiment, the high temperature resistant layer can be provided to prevent the high temperature generated by the lead 10 from burning the water bag body 1 when the lead 10 burns, thereby causing the water in the water bag body 1 to flow out and wet the burning lead, causing the blasting to fail.

[0036] As a preferred embodiment of the utility model, the high temperature resistant layer includes a polyimide layer 12 and an ice silk fiber layer 13. The polyimide layer 12 is arranged on the inner wall of the lead mounting hole 11, and the ice silk fiber layer 13 is arranged on the inner wall of the polyimide layer 12. The thickness of the polyimide layer 12 and the ice silk fiber layer 13 is 1.2-1.8 mm.

[0037] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
