Description

Technical Field

[0001] This utility model relates to the field of explosive water bag technology, and in particular to a water bag for filling explosive charges in blast holes. Background Technology

[0002] Water-filled blasting bags are suitable for various medium- and deep-hole blasting operations. They are used to evenly disperse the explosive charge in the blast hole, increase the blasting time, improve the blasting effect, reduce the pulverized rock ratio, and increase the uniformity of blasted block size. When used for filling the borehole, the dust suppression effect of water reduces blasting dust, which is beneficial to environmental protection at the blasting site.

[0003] However, existing blasting water bags are usually filled with water outside the blast hole and then placed inside. Since the blast hole depth can reach 30 meters and the water bag is disposable and has relatively weak overall strength, in order to prevent the water bag from falling directly into the blast hole and causing it to break upon impact, workers need to use a hook to put the water bag into the blast hole. The steps required to fill the water bag with water and put it into the blast hole are too cumbersome and not conducive to workers filling the water bag with water and putting it into the blast hole. Therefore, this application provides a blast hole blasting water bag to meet the requirements. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a water bag for filling propellant charges in blast holes. By setting an elastic component, after the water bag is placed inside the blast hole and filled with water, the connector can automatically separate from the water pipe connector. After the connector and the water pipe connector are separated, the connector is automatically sealed to prevent the water inside the water bag from being discharged. This allows the water bag to be filled with water inside the blast hole, thus avoiding the step of placing the water bag into the blast hole with a hook. This makes it easier for workers to place the water bag into the blast hole and solves the problem that the existing steps are too cumbersome and not conducive to workers filling the water bag and placing it into the blast hole.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A water bag for filling propellant in a blast hole includes a water bag, a connector fixedly connected to the top of the water bag, and a water pipe connector inserted into the interior of the connector; an elastic component for automatically separating the connector and the water pipe connector and sealing the connector, the elastic component being connected to the water bag and the connector.

[0007] Optionally, the elastic component includes an elastic sheet fixedly connected to the connector, and a weakening groove is formed on one side of the elastic sheet.

[0008] Optionally, the elastic sheet has a square groove inside, and the inner corners of the square groove are rounded.

[0009] Optionally, the elastic sheet has an internal mounting hole, and a connecting wire is fixedly connected inside the mounting hole.

[0010] Optionally, a positioning block is sleeved on the outer wall of the connecting line, and the positioning block is fixedly connected to the top of the water bag.

[0011] Optionally, an arc-shaped component is fixedly connected to the end of the connecting line away from the mounting hole, and the mounting hole is inserted into the interior of the connecting component.

[0012] Optionally, a sealing plate is fixedly connected to the outer wall of the arc-shaped component.

[0013] Optionally, the sealing plate is slidably connected inside the connector.

[0014] Optionally, the connector has a through groove inside.

[0015] Optionally, the sealing plate has a strip groove corresponding to the through groove.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, by setting up an elastic component, after the water bag is filled with water inside the blast hole, the connector can automatically separate from the water pipe connector. After the connector and the water pipe connector are separated, the connector is automatically sealed to prevent the water inside the water bag from being discharged. This allows the water bag to be filled with water inside the blast hole, thus avoiding the step of putting the water bag into the blast hole with a hook. This makes it easier for workers to put the water bag into the blast hole, so as to evenly distribute and block the explosives inside the blast hole and suppress the dust generated by the blast.

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0032] like Figure 1 and Figure 3 As shown, an embodiment of this utility model provides a water bag for filling explosive charges in a blast hole, including a water bag 1. The water bag 1 can be filled with gas or other fillers according to the needs of blasting. A connector 2 is fixedly connected to the top of the water bag 1, and a water pipe connector is inserted into the inside of the connector 2. An elastic component is used to automatically separate the connector 2 and the water pipe connector and seal the connector 2. The elastic component is connected to the water bag 1 and the connector 2. Through the setting of the elastic component, after the water bag 1 is placed into the blast hole and filled with water, the connector 2 can be automatically separated from the water pipe connector, and after the connector 2 and the water pipe connector are separated, the connector 2 is automatically sealed to prevent the water inside the water bag 1 from being discharged.

[0033] like Figures 2 to 5As shown, the elastic component includes an elastic sheet 3 fixedly connected to the connector 2. The end of the elastic sheet 3 is triangular, which facilitates insertion into the annular groove of the water pipe connector to fix the water pipe connector. A weakening groove 4 is provided on one side of the elastic sheet 3. The weakening groove 4 reduces the force required for the elastic sheet 3 to deform. A square groove 5 is provided inside the elastic sheet 3. The square groove 5 reduces the material required for the elastic sheet 3 as a whole, thus reducing production costs. The inner corners of the square groove 5 are rounded. An installation hole 6 is provided inside the elastic sheet 3. A connecting wire 7 is fixedly connected inside the installation hole 6. The connecting wire 7 is fixedly connected inside the installation hole 6 with glue, which improves the connection strength between the connecting wire 7 and the elastic sheet 3. A positioning block 8 is sleeved on the outer wall of the connecting wire 7. The positioning block 8 is fixedly connected to the top of the water bag 1. An arc-shaped component 9 is fixedly connected to the end of the connecting wire 7 away from the installation hole 6. The installation hole 6 is inserted into the interior of the connector 2. A sealing plate 10 is fixedly connected to the outer wall of the arc-shaped component 9. The sealing plate 10 is slidably connected inside the connector 2.

[0034] like Figure 5 As shown, the connector 2 has a through groove 11 inside, and the sealing plate 10 has a strip groove corresponding to the through groove 11. By setting the through groove 11 and the corresponding strip groove on the sealing plate 10, the sealing plate 10 and the through groove 11 can have a large water inlet space when the seal on the connector 2 is opened, and the sealing plate 10 can move a short distance to seal the through groove 11, preventing the elastic sheet 3 from deforming and resetting and failing to pull the sealing plate 10 to completely seal the connector 2.

[0035] The working principle of the technical solution provided by this utility model is as follows:

[0036] When the staff needs to insert the water bag 1 into the borehole, they first insert the water pipe connector into the connector 2. The water pipe connector is then deformed by the triangular arc surface of the elastic plate 3, allowing it to be inserted into the connector 2. Once the water pipe connector is inserted deep enough, the triangular head on the elastic plate 3 aligns with and engages with the annular groove on the water pipe connector, fixing it inside the connector 2. During the insertion process, the water pipe connector pushes the sealing plate 10 against the connector through the arc surface of the arc-shaped component 9. The internal sliding of component 2 causes the through groove 11 inside the connector 2 to coincide with the strip groove on the sealing plate 10. At this time, the seal on the water bag 1 is opened, and the operator can then place the water bag 1 into the borehole through a water pipe. After the operator places the water bag 1 in the appropriate position, the operator can connect an external water source to the water pipe and allow water to be discharged into the water bag 1 through the connector 2, causing the water bag 1 to gradually expand. When the water bag 1 is fully expanded, the folds at the top of the water bag 1 will be flattened, increasing the distance between the positioning block 8 and the connector 2, thereby allowing the positioning block 8 to be pulled through the connecting line 7. The elastic plate 3 and the arc-shaped component 9 are both connected. Because the arc-shaped component 9 is blocked and limited by the water pipe connector, the connecting line 7 can only pull the elastic plate 3 to bend and deform. This stops the elastic plate 3 from being stuck inside the annular groove of the water pipe connector, allowing the water pipe connector to detach from the inside of the connector 2. This achieves the effect of automatically separating the water pipe connector and the connector 2, allowing the water bag 1 to expand inside the borehole. This avoids the step of placing the water bag 1 into the borehole using a hook, preventing excessive friction between the water bag 1 and the inside of the borehole, and making it easier for workers to place the water bag 1 into the borehole for uniform distribution of the explosives inside. To disperse and block the dust generated by the explosion, it is important to note that after the water pipe connector separates from the connector 2, the arc-shaped part 9 loses the limitation of the water pipe connector. This allows the elastically reset elastic plate 3 to pull the arc-shaped part 9 along the inside of the connector 2 through the connecting line 7. In turn, the arc-shaped part 9 pulls the sealing plate 10 along the inside of the connector 2, causing the strip groove on the sealing plate 10 to be misaligned with the through groove 11 inside the connector 2, thus sealing the connector 2 and the water bag 1, preventing the water inside the water bag 1 from leaking out, thereby achieving the effect of automatically sealing the water bag 1.
