Description

Technical Field

[0001] This utility model belongs to the field of blasting engineering technology, specifically relating to a static and dynamic expansion force generating device based on gas generated by water electrolysis. Background Technology

[0002] In existing technologies, devices that generate strong expansion forces typically rely on chemical explosives or hydraulic technology. While chemical explosives can generate powerful expansion forces, their use is subject to strict safety and regulatory restrictions and carries high risks. Hydraulic devices, on the other hand, require complex storage and release systems and transmission mechanisms, resulting in reduced expansion forces and making miniaturization difficult.

[0003] To address the aforementioned problems, existing technologies include some miniaturized mechanical devices or expansive chemical materials. However, these mechanical devices typically generate only limited expansion force, failing to meet the demands for high-intensity expansion. Expansive chemical materials, such as quicklime, are complex to operate and pose certain health risks to construction workers and the environment. Therefore, developing a device capable of rapidly, safely, and controllably generating strong expansion force within confined spaces is of significant practical importance. Summary of the Invention

[0004] The purpose of this invention is to provide a static and dynamic expansion force generating device based on the electrolysis of water to generate gas. This device generates static expansion force by producing hydrogen and oxygen through the electrolysis of aqueous solution, and can ignite the gas with an electric spark igniter to generate instantaneous expansion force, thereby achieving a rapid, powerful and controllable expansion effect.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a static and dynamic expansion force generating device based on water electrolysis to generate gas, including a DC power supply and a thin-walled container with one open end. The thin-walled container has a cavity inside, and a container sealing head is provided at the open end of the thin-walled container. The container sealing head and the cavity form a sealed reaction chamber. An electrolyte solution is distributed in the reaction chamber. An electric spark ignition head and positive and negative solid electrodes are also provided in the reaction chamber. When the thin-walled container is placed such that the positive and negative solid electrodes (5) are partially or completely immersed in the electrolyte solution, the electric spark ignition head does not contact the electrolyte solution. Both the positive and negative solid electrodes and the electric spark ignition head are connected to the DC power supply. The thin-walled container is made of elastic material and can expand.

[0006] The thin-walled container is covered with a fast-curing sealant that encapsulates the container. The fast-curing sealant is made of expanding cement material.

[0007] The positive and negative solid-state electrodes and the electric spark ignition head are all connected to a DC power supply via wires.

[0008] When the thin-walled container expands, its maximum volume after expansion is at least twice the original volume.

[0009] The volume of the electrolyte solution accounts for 10% to 95% of the volume of the thin-walled container. The electrolyte in the electrolyte solution is one or more of the following: carbonates, sulfates, acetates, and oxalates that are easily soluble in water. When the solution undergoes an electrolysis reaction, only hydrogen and oxygen are produced.

[0010] The container sealing head is made of plastic.

[0011] The float is made of corrosion-resistant and insulating polymer material. A float floats on the surface of the electrolyte solution, and an electric spark ignition head is fixed to the top of the float. When the float floats on the surface of the electrolyte solution, at least 30% of its volume is always exposed above the liquid surface.

[0012] The positive and negative solid-state electrodes are inert electrodes.

[0013] The electric spark ignition head is made of an oxidation-resistant and corrosion-resistant alloy.

[0014] The voltage of the DC power supply can be adjusted to a low voltage acceptable to the positive and negative solid electrodes and the electric spark ignition head, or a high voltage acceptable to the positive and negative solid electrodes and the electric spark ignition head.

[0015] The DC power supply has an adjustable voltage range of 1V to 100,000V. When performing an electrolytic reaction, the supply voltage is a low voltage acceptable to the positive and negative solid electrodes and the electric spark ignition head, and the surface temperature of the electric spark ignition head does not exceed 500 degrees Celsius. When performing a gas ignition reaction, the supply voltage is a high voltage acceptable to the positive and negative solid electrodes and the electric spark ignition head, and the temperature of the electric spark ignition head can exceed 500 degrees Celsius.

[0016] The beneficial effects of this invention are: controllable expansion force is achieved through voltage regulation, avoiding the use of chemical explosives and effectively reducing safety risks; hydrogen and oxygen generated by water electrolysis are combined with an electric spark ignition head to generate high temperature and high pressure, which can provide strong expansion force; and the operation is simple and easy to control.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0019] Example 1

[0020] like Figure 1 As shown, a static and dynamic expansion force generating device based on water electrolysis to generate gas includes a DC power supply 1 and a thin-walled container 2 with one open end. The thin-walled container 2 is covered with a fast-curing sealant 10. The thin-walled container 2 has an internal cavity 8, in which an electrolyte solution 4 is distributed. When the thin-walled container 2 is placed on a platform such that positive and negative solid-state electrodes 5 are close to the platform, the positive and negative solid-state electrodes 5 are immersed in the electrolyte solution 4. The electrolyte solution 4 does not contact the upper inner wall of the thin-walled container 2. The container is sealed. 3. An electrolyte solution 4 is embedded in the opening of the thin-walled container 2 to prevent the electrolyte solution 4 from flowing out, so that the cavity 8 forms a sealed reaction chamber. The positive and negative solid electrodes 5 are connected to the DC power supply 1 through the wire 9. A float 7 floats on the top of the electrolyte solution 4. The float 7 is not completely submerged in the electrolyte solution 4. An electric spark ignition head 6 is fixed on the top of the float 7. The electric spark ignition head 6 does not contact the electrolyte solution 4 and the inner wall of the thin-walled container 2. The electric spark ignition head 6 is connected to the DC power supply 1 through the wire 9. The thin-walled container 2 is made of elastic material and can expand.

[0021] Preferably, when the thin-walled container 2 expands, the maximum volume after expansion is at least twice the original volume. It is made of an airtight, stretchable, and insulating polymer material. In this embodiment, the thin-walled container 2 is cylindrical with a diameter of 100mm, a length of 1000mm, and a wall thickness of 1mm, and is made of polyester plastic.

[0022] Preferably, the electrolyte aqueous solution 4 is a sodium sulfate solution with a volume of 3L, accounting for 38.2% of the container volume.

[0023] Preferably, the container sealing head 3 needs to have sufficient strength to withstand the pressure inside the container, good sealing performance, and insulation function. In this embodiment, the container sealing head is made of epoxy resin, and the electrolyte solution can undergo electrolysis in the sealed cavity 8.

[0024] Preferably, the float 7 is made of a corrosion-resistant and insulating polymer material, and when the float floats on the surface of the electrolyte solution, at least 30% of its volume is always exposed above the liquid surface.

[0025] Preferably, the positive and negative solid electrodes 5 are inert electrodes that do not react chemically with the electrolyte solution 4. In this embodiment, graphite rods with a diameter of 5 mm and a length of 800 mm are used.

[0026] Preferably, the voltage of the DC power supply 1 is adjustable, with a supply voltage range of 1V to 100,000V. In this embodiment, the supply voltage is 500V when electrolyzing the aqueous solution 4 and 15,000V when igniting the gas. The voltage can be controlled manually, automatically, or remotely.

[0027] Specifically, the method of using this device is as follows: turn on the DC power supply 1 to supply power to the electrode 5 and the electric spark ignition head 6. When the voltage is adjusted to an acceptable low voltage of 500V for the positive and negative solid electrodes 5 and the electric spark ignition head 6, the positive and negative solid electrodes 5 stably electrolyze the aqueous solution 4 to produce hydrogen and oxygen. An expansion force is gradually generated inside the thin-walled container 2, and the surface temperature of the electric spark ignition head 6 does not exceed 500 degrees Celsius. When the DC power supply 1 is adjusted to an acceptable high voltage of 15000V for the positive and negative solid electrodes 5 and the electric spark ignition head 6, the electrolyte solution 4 undergoes electrical breakdown and plasmaization, which can instantly produce a large amount of high-temperature water vapor. The temperature of the electric spark ignition head 6 exceeds 500 degrees Celsius and can ignite the hydrogen and oxygen mixture in the thin-walled container 2.
