The present invention relates to a multi-stage plug for creating air chambers in blast holes used in underground mining, tunneling, civil engineering, and demolition. The invention comprises two or more interconnectable modules, each incorporating conical plugs selected from finned helix plugs, plugs with wavy folds, and plugs with zigzag folds. The modules are joined by rigid spacer bars or tubes that allow for progressive adjustment of the air chamber length according to the blast design. The plugs are made of resilient plastic material that elastically reduces its diameter during insertion into the blast hole and subsequently creates a harpoon-like locking mechanism against the inner wall of the hole. This mechanism simultaneously forms the air chamber and retains the explosive within the blast hole, particularly in vertical or oblique overhead blast holes.

The present application comprises a water-tight cavity structure, which contains a water-tight cavity, and is connected with a fish hook or a harpoon through a first fishing line at one end and connected with a second fishing line at the other end. When a fish pulls the fish hook, the water-tight cavity structure is pulled to increase the volume of the water-tight cavity, thus increasing the buoyancy of the water-tight cavity structure, which helps human to pull up the fish.

The fishing gun device comprises a gun-shaped body, a fish hook, a fishing line, a trigger mechanism, a float mechanism, a sliding mechanism, a safety mechanism, a launching mechanism and a winding mechanism; the gun-shaped body has a containing cavity, the containing cavity is provided with a trajectory for guiding the float mechanism and the launching mechanism to move along a preset path; the fish hook is movably arranged in the float mechanism and connected with the winding mechanism through the fishing line; the sliding mechanism is slidably arranged on the gun-shaped body and is clamped with the launching mechanism to keep the launching mechanism in an energy storage state; the winding mechanism is used for winding and releasing the fishing line; the trigger mechanism is arranged below the winding mechanism and is clamped with the launching mechanism, triggers the winding mechanism to release the fishing line and simultaneously releases the locking of the launching mechanism, and then drives the float mechanism to be launched along the trajectory; the safety mechanism is used for preventing the launching mechanism from being misfired. The fish hook is automatically launched, the operation is simple and convenient, the safety is improved, and the fishing fun is enhanced.

The invention relates to a set of elements for mounting a photovoltaic panel by manually positioning a harpoon clamp, where the elements are intended to interact in order to mount the photovoltaic panel onto another pre-existing structure. The element group consists of a longitudinal profile on which the photovoltaic panel is arranged, a fixing clamp for fixing the longitudinal profile to a supporting structure of the longitudinal profile, and a harpoon-shaped clamp.

This invention discloses a foundation settlement detection device, including an information exchange mechanism. The information exchange mechanism includes a harpoon-shaped component, with a mounting rod fixedly connected to its top. A settlement monitoring mechanism is mounted on the top of the mounting rod, and the settlement monitoring mechanism includes an insulating panel fixedly connected to the top of the mounting rod. An information exchange block is fixedly connected to the insulating panel. A calibration mechanism enables real-time detection of foundation settlement. An adaptation mechanism transmits the detected information from the calibration mechanism to the settlement monitoring mechanism. The settlement monitoring mechanism converts the detected information into an electrical signal, which is then transmitted to a receiving terminal via the information exchange mechanism. This achieves the function of detecting foundation settlement, resulting in more accurate detection results and improving the practicality of the foundation settlement detection device.

Decorative profile comprises base, vertically oriented groove for inserting harpoon and stretch ceiling fabric, recess for installing light source, structural projections for mounting light diffuser, and light diffuser. Upper C-shaped groove is located at one end of base.
