Abstract
Description
Technical Field
[0001] The present application relates to the technical field of blasthole drainage, and in particular to a blasthole drainage device. Background Art
[0002] In open-pit mine blasting, waterproof explosives (such as emulsion explosives, water gel explosives, and heavy ammonium oil explosives) are generally used for blastholes containing water. After the waterproof explosives are loaded into the bottom of the hole, the water at the bottom of the hole is squeezed up by the waterproof explosives, and the water remains in the filling section. When filling the blastholes, drill cuttings around the blastholes are generally used. When the drill cuttings are shoveled in from the hole mouth, the water is not squeezed out, but mixed with the water in the hole into a slurry. This will significantly reduce the filling quality and cause blasting holes, which not only poses a safety hazard, but also affects the blasting effect. Therefore, in the related art, when blasting water-containing blastholes, aggregates with suitable particle sizes are generally used for filling, which will cause the problem of increased blasting costs. Utility Model Content
[0003] The purpose of the present application is to provide a blasthole drainage device, which is used to improve the problem in the related art that when waterproof explosives are used in water-containing blastholes, aggregates need to be used to fill the blastholes, thereby increasing the blasting cost.
[0004] In order to achieve the above objectives, this application provides the following technical solutions:
[0005] A blasthole drainage device is provided, which includes a water collector and a switch structure located at one end of the water collector. The switch structure includes a plugging gasket, a connecting rod and a blocking member, wherein the plugging gasket is connected to the blocking member through the connecting rod; the water collector has a receiving cavity and an opening, the plugging gasket is located in the receiving cavity, and the blocking member is located outside the receiving cavity; the distance between the blocking member and the plugging gasket is greater than the depth of the opening, and the blocking member is configured to have a gap with the opening when attached to the water collector.
[0006] In some embodiments, the blocking gasket includes a first gasket and a second gasket, the first gasket is fixed to one end of the connecting rod, and the second gasket is sleeved on the connecting rod; the edge of the positive projection of the first gasket on the second gasket is located inside the second gasket.
[0007] In some embodiments, the first gasket is made of metal material, and the second gasket is made of rubber material.
[0008] In some embodiments, the connecting rod has an external thread, and the blocking member is provided with a threaded hole matched with the external thread.
[0009] In some embodiments, the blocking member is a bar-shaped blocking member.
[0010] In some embodiments, the water collector includes a first collecting tube, one end of which has a vent, and the switch structure is located at an end of the first collecting tube away from the vent.
[0011] In some embodiments, the water collector further includes a second collecting tube and a diameter reducing portion, the second collecting tube and the first collecting tube are connected to both ends of the diameter reducing portion, and the aperture of the second collecting tube is smaller than that of the first collecting tube.
[0012] In some embodiments, the reducing portion is detachably connected to the first collecting tube.
[0013] In some embodiments, the reducing portion is threadably connected to the first collecting tube.
[0014] In some embodiments, at least one of the first collecting tube and the second collecting tube is made of PVC material.
[0015] Beneficial effects:
[0016] The blasthole drainage device provided by the present application can be directly placed in the blasthole during use, and the switch structure is always placed below the blasthole drainage device. Due to the water pressure of the accumulated water in the blasthole (or, due to the resistance of the bottom of the blasthole when the blocking member contacts the bottom of the blasthole), the switch structure will move upward; when it moves to a certain distance, the blocking member is attached to the water collector, and at this time, the blocking member is restricted by the opening and cannot continue to move upward, and the blocking gasket and the connecting rod are also restricted and cannot continue to move. In this case, the accumulated water in the blasthole enters the accommodating chamber of the water collector through the gap between the opening and the blocking member, so that the water collector can collect the accumulated water in the blasthole. After the accumulated water in the blasthole is collected, the blasthole drainage device is lifted upward. At this time, due to the water pressure and gravity in the accommodating chamber, the switch structure will move downward as a whole, and when the blocking gasket is attached to the water collector, the blocking gasket can block the opening to prevent the accumulated water in the water collector from spilling from the opening. When it is necessary to discharge the water collected in the water collector, the blasthole drainage device is placed on the ground. At this time, the blocking member contacts the ground and moves upward, so that the sealing gasket can be separated from the opening, and the water in the accommodating cavity can be smoothly discharged from the opening, thereby realizing the discharge of the water in the water collector, which is convenient for subsequent use.
[0017] In addition, the blasthole drainage device has a simple overall structure and is easy to manufacture, which can effectively reduce the manufacturing and use costs. At the same time, the blasthole drainage device also has a good function of collecting accumulated water, which is beneficial to subsequent blasting operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1As shown, when blasting a blasthole 8 containing accumulated water, waterproof explosives 9 are generally used for blasting. After the waterproof explosives are loaded into the bottom of the hole, the water at the bottom of the hole is squeezed up by the waterproof explosives, and the water remains in the filling section. In the related art, the accumulated water in the blasthole is difficult to be effectively discharged, so aggregates with suitable particle sizes are usually used for filling, but this often results in the problem of increased blasting costs.
[0035] Based on this, some embodiments of the present application provide a blasthole drainage device, please refer to Figure 1-6 , the device includes a water collector and a switch structure located at one end of the water collector. The water collector is used to collect the accumulated water in the water collector and take it out, so as to discharge the accumulated water in the blasthole. The switch structure includes a blocking gasket, a connecting rod 4 and a blocking member 7. The blocking gasket is connected to the blocking member 7 through the connecting rod 4. The water collector has a accommodating cavity and an opening; the blocking gasket is located in the accommodating cavity, and the blocking member 7 is located outside the accommodating cavity. The distance between the blocking member 7 and the blocking gasket (i.e., the distance between the top surface of the blocking member 7 and the bottom surface of the blocking gasket) is greater than the depth of the opening (i.e., the thickness of the water collector at the opening position), so that when either the blocking member 7 or the blocking gasket is attached to the water collector, there is a distance between the other and the opening in the vertical direction.
[0036] The size of the blocking member 7 is larger than the size of the opening, so that when the blocking member 7 is attached to the water collector, it can limit the switch structure from continuing to move in the direction of the accommodating cavity of the water collector; the size of the blocking gasket is larger than the size of the opening, so that when the blocking gasket is attached to the water collector, it can limit the switch structure from continuing to move in the direction away from the accommodating cavity of the water collector. In addition, the blocking gasket is configured to block the opening, so that when the blocking gasket is attached to the water collector, the blocking gasket can block the opening to prevent the accumulated water in the water collector from spilling from the opening.
[0037] The blocking member 7 is configured such that, when attached to the water collector, there is a gap between the blocking member and the opening, so that the water in the blast hole can smoothly pass through the gap into the accommodating cavity of the water collector, thereby facilitating the water collector to collect the water in the blast hole.
[0038] In the specific use of the above-mentioned blasthole drainage device, first put it into the blasthole, and make the switch structure always under the blasthole drainage device, due to the water pressure of the accumulated water in the blasthole (Alternatively, when the blocking member 7 contacts the bottom of the blasthole, due to the resistance of the bottom of the blasthole, the switch structure (blocking member 7, connecting rod 4 and blocking gasket) will move upward (i.e., toward the accommodating cavity of the water collector); when it moves to a certain distance, the blocking member 7 is attached to the water collector, and at this time, the blocking member 7 is restricted by the opening and cannot continue to move upward, and the blocking gasket and connecting rod 4 are also restricted and cannot continue to move. Figure 4 As shown in the figure, the accumulated water in the blasthole enters the receiving chamber of the water collector through the gap between the opening and the blocking member 7. The direction indicated by the arrow in the figure is the direction in which the accumulated water flows into the receiving chamber, so that the water collector can collect the accumulated water in the blasthole. After the accumulated water in the blasthole is collected, the blasthole drainage device is lifted upward. At this time, due to the water pressure and gravity in the receiving chamber, the switch structure as a whole moves downward. When the blocking gasket is attached to the water collector, as shown in the figure, Figure 5 As shown, the blocking gasket can block the opening to prevent the accumulated water in the water collector from spilling out of the opening. When the accumulated water collected in the water collector needs to be discharged, the blasthole drainage device is placed on the ground. At this time, the blocking member contacts the ground and moves upward, so that the blocking gasket can be separated from the opening, and the accumulated water in the accommodating cavity is discharged from the opening. Figure 6 As shown, the accumulated water in the water collector can be discharged, which is beneficial for subsequent use.
[0039] The blasthole drainage device has a simple overall structure, is easy to manufacture, and can effectively reduce the manufacturing and use costs. At the same time, the blasthole drainage device also has a good function of collecting accumulated water, which is beneficial to subsequent blasting operations.
[0040] In some embodiments, the blocking gasket includes a first gasket 5 and a second gasket 6, wherein the first gasket 5 is fixed to one end of the connecting rod 4, and the second gasket 6 is sleeved on the connecting rod 4, and the second gasket 6 can slide along the length direction of the connecting rod 4. The edge of the orthographic projection of the first gasket 5 on the second gasket 6 is located inside the second gasket 6, that is, when the first gasket 5 is attached to the second gasket 6, the edge of the first gasket 5 is in contact with the upper surface of the second gasket 6, and in this case, there is no gap between the first gasket 5 and the second gasket 6. In this way, the sealing performance of the blocking gasket as a whole can be well guaranteed, and the problem of poor overall use effect caused by gaps inside the blocking gasket can be avoided.
[0041] It is worth noting that when the first gasket 5 is fixed to one end of the connecting rod 4, there is no opening or gap between the first gasket 5 and the connecting rod 4, thereby ensuring that when the first gasket 5 is attached to the second gasket 6, the first gasket 5 and the second gasket 6 can effectively seal the opening to prevent accumulated water from leaking from the gap between the sealing gasket and the opening.
[0042] In some embodiments, the first gasket 5 included in the blocking gasket can also be movably arranged at one end of the connecting rod 4. In this case, a blocking block is provided at one end of the connecting rod 4 to limit the range of movement of the first gasket 5. In this case, when the first gasket 5 is attached to the blocking block, there is no gap between the two, so as to ensure the sealing between the blocking gasket and the blocking block, thereby avoiding the problem of poor overall use effect caused by poor sealing between the blocking gasket and the connecting rod 4.
[0043] In some embodiments, the first gasket 5 is made of metal material, which can make the first gasket 5 have a certain degree of rigidity and prolong its service life. Of course, the first gasket 5 can also be other rigid hard materials to prevent it from easily moving through the opening to the outside of the water collector.
[0044] The second gasket 6 is made of rubber material, which can better ensure that the second gasket 6 has good sealing performance, so as to prevent a small amount of accumulated water from leaking out after the plugging gasket blocks the opening, thereby affecting the overall drainage effect. Of course, the second gasket 6 can also be made of other materials with certain sealing performance, as long as it can prevent the accumulated water from leaking out through the gap between the second gasket and the accumulated water collector when the second gasket 6 is attached to the opening position.
[0045] In some examples, such as Figure 2 As shown, the first gasket 5 and the second gasket 6 are both columnar structures (for example, both are cylindrical), which is conducive to the manufacture of the above-mentioned gaskets and can also well ensure the overall stability. In addition, the horizontal cross-sectional shape of the opening can be circular, and the diameter of the opening is smaller than the diameter of the second gasket 6, so that the second gasket 6 can be well sealed when attached to the water collector.
[0046] In some examples, the diameter of the first gasket 5 is larger than the diameter of the opening, which helps to ensure that the first gasket 5 is always located in the water collector, thereby preventing the first gasket 5 and the second gasket 6 from falling off the water collector through the opening when the second gasket 6 is too soft.
[0047] In some examples, the diameter of the first gasket 5 is smaller than the diameter of the second gasket 6 , which can avoid the waste of materials and increase in device manufacturing costs due to the first gasket 5 having an excessively large diameter.
[0048] In some embodiments, the connecting rod 4 has an external thread, and a threaded hole matching the external thread is provided on the blocking member 7. In this way, the blocking member 7 is rotatably connected to the connecting rod 4, and by rotating the blocking member 7, the distance between the blocking member 7 and the blocking gasket can be adjusted, thereby controlling the flow of accumulated water entering the water collector (or being discharged from the water collector) and the minimum depth of water entering the accommodating chamber, thereby controlling the overall working progress.
[0049] In some embodiments, the blocking member 7 is a strip-shaped blocking member, so that the blocking member 7 has a smaller cross-section, thereby making the gap between the blocking member 7 and the opening larger, thereby improving the efficiency of accumulated water entering the water collector and the efficiency of accumulated water being discharged from the water collector.
[0050] Exemplarily, the blocking member 7 may be cylindrical or prismatic, and the threaded hole is provided through the blocking member 7 in a radial direction, so as to ensure a larger gap between the blocking member 7 and the opening.
[0051] In some embodiments, the blocking member 7 may also be in other shapes, as long as its horizontal size is larger than the diameter of the opening, and a gap is left when the blocking member 7 is attached to the opening for water to enter the accommodating cavity. This application does not impose any restrictions on this.
[0052] In some embodiments, Figure 1 As shown, the water collector includes a first collecting tube 3, one end of which has a vent, and the switch structure is located at the end of the first collecting tube 3 away from the vent. In this way, the vent can be used to keep the air pressure of the accommodating cavity of the water collector consistent with the external atmospheric pressure, so that the accumulated water in the blasthole can more easily enter the accommodating cavity through the switch structure, thereby improving the efficiency of the accumulated water entering the water collector.
[0053] In some embodiments, the water collector further includes a second collecting tube 1 and a reducing part 2. The second collecting tube 1 and the first collecting tube 3 are connected at both ends of the reducing part 2. The aperture of the second collecting tube 1 is smaller than that of the first collecting tube 3. By adjusting the size of the water collector through the reducing part 2, the first collecting tube 3 can be more adapted to the inner diameter of the blasthole, so that the first collecting tube 3 can occupy a larger space in the blasthole, forcing more water in the blasthole to enter the accommodating cavity. In addition, the size of the second collecting tube 1 is relatively small, which is conducive to saving materials, reducing the volume of the water collector, and facilitating its transportation; it is also conducive to the staff to grab the water collector, which is conducive to subsequent drainage operations.
[0054] In some embodiments, the reducing portion 2 is detachably connected to the first collecting tube 3, so that the first collecting tube 3 can be replaced through the reducing portion 2, thereby facilitating the selection of the first collecting tube 3 that adapts to the inner diameter of the blasthole for use, thereby achieving a better blasthole drainage effect.
[0055] Exemplarily, the reducing portion 2 is threadedly connected to the first collecting tube 3, so that the first collecting tube 3 can be quickly replaced. In addition, the threaded connection method is conducive to ensuring the connection stability between the reducing portion 2 and the first collecting tube 3, and on the other hand, it can also ensure good sealing between the reducing portion 2 and the first collecting tube 3 to prevent water from leaking from the connection between the two.
[0056] In some examples, the diameter reducing portion 2 and the second collecting tube 1 may be integrally formed to ensure connection stability and sealing performance between the two.
[0057] In some embodiments, the first collecting tube 3 and / or the second collecting tube 1 are made of PVC material. This can make them lighter in weight, making it easier for workers to pick up and carry them. In addition, the collecting tubes made of PVC material are low in cost and can carry heavier accumulated water, so they have lower overall cost and better drainage effect. Of course, the first collecting tube 3 and the second collecting tube 1 can also be made of other lightweight hard materials, which is not limited in this application.
[0058] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
