Description

Technical Field

[0001] This application belongs to the technical field of blasting demolition, and particularly relates to a water pumping device applicable to blasting holes. Background Art

[0002] In open-pit mine blasting operations, water accumulation in the blast holes due to rainfall and complex geological conditions is a common problem. The presence of water accumulation will seriously affect the blasting effect, so the water in the holes must be completely drained before charging. Currently, the mainstream method for draining water accumulation is to use an air compressor connected to an air duct for water blowing operations, and this method shows the advantages of high efficiency and speed in most blasting areas with a large amount of water accumulation.

[0003] However, in the actual operation process, we have also found some limitations of the existing technologies. Especially in those blasting areas with only a few waterlogged blast holes, using an air compressor for water blowing operations is particularly time-consuming and laborious, and it is lacking in terms of economy and environmental protection. In addition, due to the progress of construction, in some blasting areas, the holes were not charged and blasted in time after drilling, resulting in the inability of mechanical equipment to enter the later construction roads. In this case, the conditions for using machinery for water blowing are completely lost, and only charging and blasting can be directly carried out in the waterlogged blast holes, which will undoubtedly greatly reduce the blasting effect.

[0004] In summary, the existing technologies have certain limitations in dealing with water accumulation in open-pit mine blasting holes, especially in dealing with a small number of waterlogged blast holes and blasting areas where machinery cannot enter. Therefore, there is an urgent need for a more efficient, economical and environmentally friendly method for draining water accumulation to overcome the defects of the existing technologies and improve the overall effect of blasting operations.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0034] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0035] To illustrate the technical solutions described in this application, the following will be described through specific embodiments.

[0036] Please refer to Figures 1 to 8 As shown, the embodiment of this application provides a water pumping device applicable to blasting holes, which shows significant beneficial effects in aspects such as simplifying the structure, improving the drainage efficiency, reducing the use cost, and enhancing the overall effect of blasting operations.

[0037] Specifically, the water pumping device applicable to blasting holes provided by the embodiment of this application includes: a pipe body 2, a handle 1 provided at the top of the pipe body 2, and a gravity self-closing plug structure 3 provided at the bottom of the pipe body 2.

[0038] The gravity self-closing plug structure 3 is used to float relative to the bottom of the pipe body 2 when immersed in accumulated water to open the water inlet 22 at the bottom of the pipe body 2. The gravity self-closing plug structure 3 is also used to sink relative to the bottom of the pipe body 2 when being lifted to close the water inlet 22.

[0039] The working principle of the above-mentioned water pumping device applicable to blasting holes is as follows:

[0040] When the device is lowered into the accumulated water, the gravity self-closing plug structure 3 is pushed upward under the action of the water pressure difference, and water flows into the interior of the pipe body 2 from the bottom water inlet 22. When the device is lifted upward, the gravity self-closing plug structure 3 sinks under its own gravity to close the bottom water inlet 22, and the water cannot flow out and is stored inside the pipe body 2. When the device is taken out of the blasting hole and drainage is required, the water can be directly poured out from the opening at the top of the pipe body 2.

[0041] In some embodiments, when the device is taken out of the blasting hole and drainage is required, the device can also be leaned against the ground obliquely to make the gravity self-closing plug structure 3 push upward, and then drainage can be achieved. Specifically, a bottom disc bracket 23 is provided at the bottom of the pipe body 2, and a central through hole 21 and a water inlet 22 are provided on the bottom disc bracket 23. The gravity self-closing plug structure 3 includes a central column 33 for passing through the central through hole 21, a soft pad 32 provided at the top of the central column 33, a top disc 31 provided on the soft pad 32, and a bottom round bolt 34 provided at the bottom of the central column 33. Among them, the water inlet 22 is also used as the drainage port for the accumulated water inside the pipe body 2.

[0042] In some embodiments, the top disc 31, the middle column 33, and the bottom round bolt 34 are all metal parts. When the device is lifted upward, the gravity self-closing structure 3 sinks under its own gravity to close the bottom water inlet 22.

[0043] In some embodiments, the soft pad 32 is a rubber soft pad 32, which plays a role in water seal and airtightness.

[0044] In some embodiments, the bottom round bolt 34 and the middle column 33 are connected by threads, which can be easily disassembled and installed.

[0045] It should be noted that a pumping device applicable to blasting blast holes provided by the embodiments of the present application is particularly applicable to the following situations: (1) after the blast holes are drilled, the number of water holes is small, and it is uneconomical to use mechanical water blowing; (2) the terrain conditions are complex, and the machinery cannot enter the blast area to handle the water holes.

[0046] Therefore, the above-mentioned pumping device applicable to blasting blast holes has a simple and light structure, can quickly and effectively drain the accumulated water in the blast holes, each component can be quickly disassembled and assembled, and when a certain component is damaged, it can be replaced separately without replacing the entire device, effectively solving the limitations in the prior art, and thus improving the overall effect of open-pit mine blasting operations.

[0047] The above-described embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
