Description

Technical Field

[0001] The utility model relates to the technical field of underwater static blasting, in particular to an installation device for underwater static breaking agent. Background Art

[0002] In the process of dredging waterways and constructing port terminals, it is often necessary to use underwater blasting to break and remove underwater rocks. The energy generated by blasting in this process damages the nearby rock masses and the structures of the structures, reducing the stability of the structures. Usually, the construction party will set up shock-absorbing holes and bubble curtains around the structures and other measures to protect the structures, but such protective measures will greatly increase the workload and are not economical. At this time, if static blasting is used, the above problems can be well solved. When using a static breaking agent on land, the static breaking agent used in static blasting needs to be first mixed with water into a solvent and then poured into the blasting hole. However, when underwater, the static breaking agent cannot be directly poured in, and the water environment will also dilute the breaking agent, resulting in a decline in the effect of the static breaking agent.

[0003] Therefore, it is necessary to design an installation device for underwater static breaking agent to overcome the above problems. Content of the Utility Model

[0004] In order to avoid the above problems, an installation device for underwater static breaking agent is provided, which has a simple structure, is convenient to operate, can quickly place the medicine bag in the designated position, is safe and stable, flexible and practical, can be reused, and has a low cost.

[0032] As Figures 1 to 4 shown, an underwater static fracturing agent installation device provided in this embodiment includes: a cylinder body 1, a medicine bag 2, a cover 3 and a release device 4. Among them, the medicine bag 2 is used to fill the static fracturing agent and is placed inside the cylinder body 1. The cover 3 is detachably installed at the upper end of the cylinder body 1. A lifting ring 21 is provided at the top of the medicine bag 2, and the lifting ring 21 is connected to the release device 4, and the release device 4 is installed on the cover 3. By controlling the release device 4, it is thus possible to control whether the medicine bag 2 is suspended on the release device 4 through the lifting ring 21.

[0033] At the same time, the release device 4 includes a body 41, a bolt 42 and a driving component. The body 41 is fixed on the cover 3. One end of the bolt 42 is movably installed on the body 41 along its length direction. The other end of the bolt 42 passes through the lifting ring 21, and the driving component is drivingly connected to one end of the bolt 42 and drives it to move on the body 41. In this embodiment, the driving component includes a motor 43 and a gear 44. The motor 43 is arranged on the body 41, the gear 44 is coaxially installed on the output shaft of the motor 43, and a plurality of teeth 45 meshing with the gear 44 are arranged on one end of the bolt 42.

[0034] For structural stability, the main body 41 and the cover 3 are integrally formed, and a slot for inserting the other end of the bolt 42 is provided on the main body 41. After the lifting ring 21 is hung on the bolt 42, the other end of the bolt 42 is driven to insert into the slot, and the lifting ring 21 will not fall off the bolt 42, ensuring the safe and stable suspension of the medicine bag 2. Start the motor 43, the gear 44 rotates, and the bolt 42 moves telescopically under the drive of the gear 44. When the other end of the bolt 42 disengages from the slot, or the bolt 42 moves inwards and retracts into the main body 41, it is convenient for the lifting ring 21 to disengage or hang on the bolt 42. After the lifting ring 21 is hung on the bolt 42, the bolt 42 is moved outwards and inserted into the slot, and the lifting ring 21 hung on the bolt 42 will not fall off, ensuring that the medicine bag 2 is stably hung on the bolt 42, facilitating the operator to conveniently place the medicine bag 2 together with the cylinder body 1 into the designated position. During the actual control operation process, the motor 43 is controlled and connected by a controller, and the motor 43 is adjusted and controlled by adjusting the controller, thereby controlling the suspension and dropping of the medicine bag 2, which is simple, convenient, flexible and practical.

[0035] To facilitate the placement and dropping of the medicine bag 2, the cylinder body 1 is a cylindrical structure with openings at both the upper and lower ends, made of stainless steel material, which allows the medicine bag 2 to pass freely through the upper and lower ends and can also protect the medicine bag 2. At the same time, the medicine bag 2 is made of plastic material, and an injection port 22 for injecting static blasting agent is provided on the medicine bag 2.

[0036] A tether ring 5 is provided on the cover 3 or the releaser 4 to facilitate placing the entire device into the designated position. At the same time, a hollow is provided on the cover 3 to facilitate the passage of water flow and gas, ensuring that the medicine bag 2 can be quickly and stably placed in the designated place.

[0037] During the actual use process, the construction worker can first place the medicine bag 2 into the cylinder body 1, then pour static blasting agent into the medicine bag 2 from the injection port 22, and then block the injection port 22; control the motor 43 through the controller to retract the bolt 42 into the main body 41, and then place the lifting ring 21 at the position where the bolt 42 passes through; then control the motor 43 to extend the bolt 42 through the lifting ring 21 until it inserts into the slot; next, cover the cover 3 on the cylinder body 1. Finally, the construction worker ties a thin rope to the tether ring 5 and places the entire device into the underwater blasting hole through the sleeve of the drill and blast boat; the device will sink to the bottom of the hole under its own weight. At this time, the construction worker on the water surface can control the motor 43 to retract the bolt 42 through the controller to release the medicine bag 2. After the medicine bag 2 is released, the construction worker can lift the device up again through the thin rope to achieve the reuse of the device. After the medicine bag 2 sinks to the bottom and the device is recovered, the construction worker fills the upper part of the blasting hole with gravel from the sleeve to reduce the contact between the medicine bag 2 and the water body; the static blasting agent inside the medicine bag 2 expands under chemical action, continues to expand after bursting the medicine bag 2 until it contacts the hole wall, and acts on the hole wall with the expansion force generated by the chemical action, thereby achieving the purpose of cracking the rock mass.

[0038] The device has a simple structure, convenient operation, can quickly place the medicine bag 2 in the designated position, is safe and stable, flexible and practical, reusable, and has low cost.

[0039] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention 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 recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
