Description

Technical Field

[0001] The utility model relates to the technical field of open-pit mine blasting, in particular to a water intake device for an open-pit mine blasting water hole. Background Art

[0002] The blasting technology measures usually used in open-pit mines for bench mining are medium-deep hole blasting, which can fundamentally improve the safety hazards such as floating stone rolling and flying stone impact after blasting in open-pit mines, and is a strong technical support for ensuring the safety of open-pit mines. The open-pit mine slope adopts controlled blasting technology measures, through the pre-splitting blasting method, and reasonably selects relevant parameters to achieve the stability of slope blasting safety.

[0003] Currently in open-pit mine blasting construction, after the charging of some water holes is completed, the water level overflows to the hole mouth. If the water in the hole is not taken out, it will lead to problems such as long filling time and poor filling quality, affecting the blasting construction efficiency and blasting construction effect.

[0004] The existing water extraction is mainly done by manually extracting water with a bucket or by hanging a water pump into the hole to pump water. However, manual bucket water extraction is affected by the bucket structure. When taking water, the bucket will float on the liquid surface. Moreover, due to the limitation of the diameter of the blasthole, it is not convenient to swing the bucket left and right to achieve the purpose of water intake. Pumping water with a water pump is limited by the diameter of the water pump, resulting in the inability to extract water from small-diameter blastholes, and the flexibility of use is poor.

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] At the same time, in the description of this specification, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0028] The existing methods of extracting water from blastholes are mainly to use manual buckets or to lift water into the holes through water pumps. However, manual bucket water extraction is affected by the structure of the bucket. When extracting water, the bucket will float on the liquid surface. In addition, due to the limitation of the diameter of the blasthole, it is not convenient to swing the bucket left and right to achieve the purpose of water intake. Pumping water with a water pump is limited by the diameter of the pump, resulting in the inability to extract water from small-diameter blastholes, and poor flexibility in use.

[0029] Therefore, the design concept of the present application is to restructure the water bucket so that it no longer floats on the liquid surface and affects water intake. The manufacturing cost of the water bucket is very low, and water buckets of different diameters can be manufactured for different blasthole diameters, making it highly flexible to use.

[0030] like Figure 1-2As shown, the present application provides a water intake device for blasting water holes in open-pit mines, comprising a hollow cylindrical water intake bucket 1 with upper and lower openings, the water intake bucket 1 being movably connected with a water intake rod 2, the bottom of the water intake rod 2 extending out of the lower port of the water intake bucket 1 is connected with a barrel plug 3, the bottom of the barrel plug 3 is provided with a counterweight block 4, the upper part of the water intake rod 2 is provided with a limit rod 5, and the top of the water intake rod 5 is connected with a pull rope 6.

[0031] The barrel plug 3 is detachably connected to the lower port of the water-drawing bucket 1; when in use, the barrel plug 3 and the lower port of the water-drawing bucket 1 are separated and closed according to actual conditions.

[0032] The barrel plug 3 adopts a truncated cone structure; the design of the truncated cone structure is more conducive to plugging the lower port of the water bucket 1.

[0033] The barrel plug 3, the counterweight block 4 and the water-taking rod 2 are respectively threadedly connected; the three are detachably threadedly connected, which is more conducive to replacing water-taking barrels of different diameters and adapting to blastholes of different diameters.

[0034] The length of the limiting rod 5 is greater than the diameter of the upper port of the water collecting bucket 1; the limiting rod 5 is designed not only to limit the water collecting rod 2 from sinking all the time, but also to not block the upper port of the water collecting bucket 1 to avoid hindering the outflow of gas.

[0035] A limiting mechanism is arranged in the water-drawing bucket 1, and the limiting mechanism comprises a bracket 7, a limiting hole is arranged on the bracket 7, and the water-drawing rod 2 is slidably connected to the limiting hole; wherein, two limiting mechanisms are arranged alternately at upper and lower positions.

[0036] The water-drawing bucket 1 is in the shape of an elongated cylinder, and therefore, the water-drawing rod 2 may deviate when sinking and rising, resulting in the bucket plug 3 not being plugged smoothly. Therefore, the present application sets a limit mechanism to limit the moving route of the water-drawing rod 2 to avoid deviation.

[0037] The use of this application, such as Figure 2 As shown, when taking water, the counterweight 4 sinks, bringing the water-taking rod 2 down with it, the barrel plug 3 separates from the lower port of the water-taking bucket 1, the water in the blast hole enters the water-taking bucket 1, and the air in the water-taking bucket 1 is discharged from the upper port of the water-taking bucket 1. When the pull rope 6 is pulled, the water-taking rod 2 rises, bringing the barrel plug 3 up with it and connecting with the lower port of the water-taking bucket 1, and the lower port of the water-taking bucket 1 is closed. When the water is pulled to the ground, the lower port of the water-taking bucket 1 is placed on the ground water storage bucket, the water-taking rod 2 is pressed, the barrel plug 3 separates from the lower port of the water-taking bucket 1, and the water in the water-taking bucket 1 flows to the ground water storage bucket, and the above steps are repeated until the water in the blast hole is cleaned up.

[0038] Although the present invention has been described in detail with reference to the accompanying drawings and in combination with preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, ordinary technicians in the field can make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions should all be within the scope of the present invention. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should all be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
