Description

Technical Field

[0001] This invention relates to the technical field of power equipment, and more particularly to a replaceable three-section electric shovel fire extinguishing device inside an electrical cabinet. Background Technology

[0002] In open-pit mining, electric shovels are crucial production equipment. However, the underground coal dust is abundant, and the shovels operate in this harsh environment for extended periods. During coal excavation, a large amount of coal dust is generated inside the electrical cabinet. This dust settles on electronic components and accumulates at the bottom of the cabinet. The complex wiring within the cabinet, with numerous electronic components and many connection points, leads to wear and aging of the wiring over time, potentially causing fires inside the cabinet. Because the shovel operator's cab is on the top floor, a fire inside the cabinet may not be immediately detected. The operator only descends to investigate after a component malfunctions and the shovel system issues a fault code, making it difficult to control the fire promptly. Furthermore, coal dust fires often smolder at the bottom, and without careful inspection, problems go undetected, resulting in further damage to components and cables. Even after a fire breaks out, the operator may immediately disconnect the power to attempt a rescue. However, the capacitor banks inside the cabinet are not properly discharged after power is cut off, leaving residual current. If other personnel attempt a rescue blindly, there is a risk of electric shock.

[0003] Currently, the electrical cabinets in the electrical compartment of electric shovels are not equipped with fire extinguishing devices, so only passive protection measures can be adopted, such as laying fireproof cotton at the bottom, laying fireproof sandbags in the gaps, and using flame-retardant rubber to seal the holes to prevent other parts from catching fire.

Sealing assembly one and sealing assembly two are stably connected, maintaining the seal at the connection. The clamping assembly fixes sealing assembly two and the limiting assembly to the mounting assembly, thus limiting the tank unit, gas storage assembly, and spray assembly. This prevents the tank from shaking when the pressure inside the tank unit increases, thus avoiding shaking at the connection points between the two sets of pipe assemblies and the gas storage assembly and the spray assembly, which would lead to unstable connections and reduced airtightness at the connection points. The detection assembly detects whether a fire has occurred inside the cabinet. If a fire occurs, the gas storage assembly is activated, and gas enters the tank unit, mixes with the fire extinguishing material inside the tank unit, and generates a certain pressure. Subsequently, it is sprayed out through the spray assembly to extinguish the fire. Attached Figure Description

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0035] Example 1, referring to Figure 1-5 This invention provides a first embodiment of a replaceable three-section electric shovel fire extinguishing device for use within an electrical cabinet. The device includes a housing unit 100, a tank unit 200, and a connecting unit 300. The connecting unit 300 stably connects the tank unit 200 to the pipes within the housing unit 100, ensuring stable installation of the tank unit 200 within the housing unit 100. This prevents instability caused by pressure buildup from gas mixing inside the tank unit 200, thus avoiding gas leakage at pipe connections.

[0036] The housing unit 100 includes a housing 101, a battery 102 detachably disposed within the housing 101, a gas storage assembly 103 disposed within the housing 101, a spray assembly 104 disposed within the housing 101, a detection assembly 105 disposed on the gas storage assembly 103 and connected to the housing 101, and an installation assembly 106 disposed within the housing 101. The detection assembly 105 detects whether a fire has occurred inside the housing. If a fire occurs, the gas storage assembly 103 is activated, and gas enters the tank unit 200, mixes with the fire extinguishing material inside the tank unit 200, and generates a certain pressure. The gas is then sprayed out through the spray assembly 104 to extinguish the fire. The housing 101 has an independent battery 102 for power supply, eliminating the need for external wiring and preventing the device from becoming unusable after a power outage.

[0037] The tank unit 200 includes a tank 201, a limiting component 202 disposed on the tank 201 and detachably connected to the mounting assembly 106, and a pipe assembly 203 disposed on the tank 201 and detachably connected to the gas storage assembly 103 and the injection assembly 104. The tank 201 is coated with fire-retardant material. Two sets of pipe assemblies 203 are provided, arranged vertically. The upper set of pipe assemblies 203 is used for air intake and communicates with the gas storage assembly 103, while the lower set is used for air outlet and communicates with the injection assembly 104. The limiting component 202 mounts the tank 201 onto the mounting assembly 106, facilitating adjustment of the overall orientation of the tank unit 200 and ensuring alignment and proper installation of the two sets of pipe assemblies 203 with the gas storage assembly 103 and the injection assembly 104. The limiting component 202 allows for detachable installation of the tank 201, and the installation structure is simple and easy to replace.

[0038] The connecting unit 300 includes a sealing component 301 slidably disposed on the gas storage component 103, a clamping component 302 disposed on the sealing component 301, and a sealing component 303 disposed on the pipeline component 203. The rotation of the sealing component 303 allows the sealing component 301 and the sealing component 303 to engage stably, ensuring a stable and rapid connection between the pipeline component 203, the gas storage component 103, and the injection component 104. This also guarantees airtightness during connection, preventing leakage at the connection point caused by pressure buildup inside the tank 201. Furthermore, the movement of the sealing component 303 drives the clamping component 302 to move, which stably limits the limiting component 202 to the mounting component 106, thus enabling stable installation of the two sets of pipeline components 203, the gas storage component 103, and the injection component 104.

[0039] During use, the tank unit 200 is placed on the mounting assembly 106. Rotating the tank unit 200 aligns the two sets of pipe assemblies 203 with the gas storage assembly 103 and the injection assembly 104. Then, the rotation of sealing assembly one 301 causes sealing assembly two 303 to move, thereby moving the clamping assembly 302. Sealing assembly one 301 and sealing assembly two 303 are stably connected, maintaining a tight seal at the connection. The clamping assembly 302 secures both sealing assembly two 303 and the limiting assembly 202 to the mounting assembly 106, thus ensuring the tank unit 200 and the gas storage assembly 104 are aligned. Both component 103 and spray component 104 are limited to prevent the tank 201 from shaking when the pressure inside the tank unit 200 increases. This would prevent shaking at the connection points between the two sets of pipe components 203 and the gas storage component 103 and spray component 104, resulting in unstable connections and reduced airtightness at the connections. The detection component 105 detects whether a fire has occurred inside the cabinet. If a fire occurs, the gas storage component 103 is activated, and the gas enters the tank unit 200, mixes with the fire extinguishing material inside the tank unit 200, and generates a certain pressure. Subsequently, it is sprayed out through the spray component 104 to extinguish the fire.

[0040] Example 2, refer to Figure 1-5 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the through hole 106g allows the rotating ring plate 106c to rotate synchronously with the tank unit 200, offsetting the first opening 106e and the second opening 106f, making the installation of the tank unit 200 more stable; a limiting hole 106d is provided to facilitate the passage of the clamping assembly 302, stably limiting the sealing assembly 301, the second sealing assembly 303, the gas storage assembly 103, and the injection assembly 104, making the installation of the gas storage assembly 103 and the injection assembly 104 more stable, and also making the installation at the connection point more stable.

[0041] Compared to Embodiment 1, the mounting assembly 106 further includes a mounting plate 106a disposed on the inner wall of the housing 101, a support ring plate 106b disposed on the mounting plate 106a, and a rotating ring plate 106c slidably disposed on the inner circumferential surface of the support ring plate 106b. The rotating ring plate 106c supports the limiting assembly 202. When the tank unit 200 is rotated, the rotating ring plate 106c rotates synchronously, enabling adjustment of the position of the tank unit 200.

[0042] Preferably, the support ring plate 106b is provided with a limiting hole 106d that cooperates with the clamping assembly 302, and the support ring plate 106b is provided with an opening 106e for the pipe assembly 203 to pass through; the rotating ring plate 106c is provided with an opening 106f for the pipe assembly 203 to pass through, and the rotating ring plate 106c is provided with a through hole 106g that cooperates with the limiting assembly 202. The openings 106e and 106f allow the lower pipe assembly 203 to pass through for installation of the tank unit 200. Simultaneously, the through hole 106g allows the rotating ring plate 106c to rotate synchronously with the tank unit 200, offsetting the openings 106e and 106f for more stable installation of the tank unit 200. A limiting hole 106d allows the clamping assembly 302 to pass through, providing stable positioning for the sealing assembly 301, sealing assembly 303, gas storage assembly 103, and injection assembly 104.

[0043] Preferably, the gas storage assembly 103 includes a gas storage tank 103a disposed within the housing 101, a flow pipe 103b disposed on the gas storage tank 103a, a selector valve 103c disposed on the flow pipe 103b, a connecting pipe 103e disposed on the flow pipe 103b, and a selector valve locking mechanism 103d disposed on the flow pipe 103b. The connecting pipe 103e has three sets, capable of connecting to three tank units 200. The three tank units 200 store different fire extinguishing materials and can respond to multiple fires. The detection component 105 detects whether a fire has occurred inside the cabinet and transmits the signal to the solenoid valve 105a. The solenoid valve 105a opens the control selection valve 103c and the control selection valve locking mechanism 103d. The gas in the gas storage tank 103a enters different tank units 200 through the flow pipe 103b and the connecting pipe 103e, mixes with the fire extinguishing material in the tank unit 200, and is then sprayed out by the spray component 104 to extinguish the fire.

[0044] Furthermore, the spray assembly 104 includes an outlet pipe 104a disposed within the housing 101, an inlet pipe 104b disposed on the outlet pipe 104a and detachably connected to the pipe assembly 203, and a rotary nozzle 104c rotatably disposed at the outlet end of the outlet pipe 104a; the rotary nozzle 104c is rotatably disposed on the housing 101, with its outlet end extending out of the housing 101. The extinguishing gas sprayed from the tank unit 200 enters the outlet pipe 104a through the inlet pipe 104b and is sprayed by the rotary nozzle 104c towards the fire location for fire extinguishing. A solenoid valve two is provided at the connection between the outlet pipe 104a and the rotary nozzle 104c, which can control the amount of extinguishing agent sprayed by the rotary nozzle 104c, adjusting it according to the size of the fire to avoid waste of extinguishing agent.

[0045] Furthermore, the detection component 105 includes a solenoid valve 105a mounted on the gas storage tank 103a, a wiring 105b mounted on the solenoid valve 105a, and a detector 105c mounted on the housing 101 and connected to the wiring 105b. The detector 105c includes a temperature detector 105d and a smoke detector 105e. The temperature detector 105d and the smoke detector 105e detect whether a fire has occurred inside the cabinet and transmit the signal to the solenoid valve 105a. The solenoid valve 105a controls the gas storage component 103a, allowing gas to enter different tank units 200, mix with the fire extinguishing material inside the tank unit 200, and then be sprayed out by the spray component 104 to extinguish the fire.

[0046] The remaining structure is the same as that in Example 1.

[0047] Example 3, referring to Figure 1-8 This is the third embodiment of the present invention, which differs from the second embodiment in that: rotating the fixed ring 303c causes the rotating ring 303a to engage with the external threaded ring 203c. The rotating ring 303a moves until the external threaded ring 303b engages with the internal threaded groove 301e. At this time, rotating the rotating ring 303a causes the external threaded ring 303b to drive the sliding sleeve 301a to move, thereby causing the sealing component 301 and the sealing component 303 to approach and press against each other. The sealing component 303 presses against the sealing rubber ring 301d, improving the sealing performance between the sealing component 301 and the connecting pipe 103e, and pressing the sealing ring 303d tightly within the sealing ring groove 301f, thereby further ensuring the sealing performance at the connection. The clamping plate 302b, along with the movement of the sliding sleeve 301a, engages with the limiting hole 106d and the limiting hole 202c, thereby achieving stable positioning of the tank unit 200 and the connecting unit 300.

[0048] Compared to Embodiment 2, the limiting component 202 further includes a fixed ring plate 202a disposed on the tank body 201, and a plurality of locking posts 202b disposed on the bottom surface of the fixed ring plate 202a. By setting the fixed ring plate 202a and the plurality of locking posts 202b, the limiting component 202 and the rotating ring plate 106c can be rotated synchronously.

[0049] The fixed ring plate 202a has a limiting hole 202c on its side. The limiting hole 202c allows the clamping assembly 302 to pass through and stably limit the position of the fixed ring plate 202a.

[0050] Furthermore, the pipeline assembly 203 includes a pipeline 203a disposed on the tank 201, a check valve 203b disposed on the pipeline 203a, and an external threaded ring 203c disposed on the pipeline 203a away from the tank 201. By providing the check valve 203b to prevent gas backflow under pressure, the external threaded ring 203c engages with the sealing assembly 303, enabling the sealing assembly 303 to move on the pipeline 203a.

[0051] Furthermore, the sealing component 301 includes a sliding sleeve 301a slidably disposed on the outer peripheral surface of the gas storage component 103, a sliding column 301b disposed on the outer peripheral surface of the sliding sleeve 301a, a guide block 301c disposed on the gas storage component 103 and slidingly rubbing against the sliding column 301b, and a sealing rubber ring 301d disposed on the inner peripheral surface of the sliding sleeve 301a. The guide block 301c is a U-shaped block, and the sliding column 301b slides and rubs against the inner peripheral surface of the U-shaped block; the movement of the sealing component 303 and the sealing rubber ring 301d mutually compress each other, improving the sealing performance between the sealing component 303 and the sealing component 301, and improving the sealing performance between the connecting pipe 103e and the pipe 203a.

[0052] Preferably, the inner circumferential surface of the sliding sleeve 301a is provided with an internal threaded groove 301e that mates with the sealing component 303, and the end face of the sliding sleeve 301a facing the tank unit 200 is provided with a sealing ring groove 301f. When the sealing component 303 rotates, the internal threaded groove 301e that mates with it drives the sliding sleeve 301a to move, so that the sealing component 303 and the sealing component 301 approach each other and are squeezed together.

[0053] In particular, the clamping assembly 302 includes a connecting plate 302a disposed on the outer peripheral surface of the sliding sleeve 301a, a clamping plate 302b disposed on the connecting plate 302a, and a reinforcing plate 302c disposed on the connecting plate 302a and connected to the clamping plate 302b. The clamping plate 302b engages with the limiting hole 106d and the limiting hole 202c, thereby achieving stable positioning of the tank unit 200 and the connecting unit 300.

[0054] Preferably, the sealing assembly 303 includes a rotating ring 303a rotatably mounted on the pipe assembly 203, an externally threaded ring 303b disposed on the outer circumferential surface of the rotating ring 303a and threadedly engaged with the internally threaded groove 301e, a fixed ring 303c disposed on the outer circumferential surface of the rotating ring 303a, a sealing ring 303d disposed on the fixed ring 303c and engagedly inserted into the sealing ring groove 301f, and a sealing rubber ring 303e disposed on the inner circumferential surface of the rotating ring 303a. The sealing rubber ring 303e is pressed tightly against the externally threaded ring 303c, improving the airtightness of the device. Rotating the fixed ring 303c causes the rotating ring 303a to engage with the external threaded ring 203c. The rotating ring 303a moves until the external threaded ring 303b engages with the internal threaded groove 301e. At this point, rotating the rotating ring 303a causes the external threaded ring 303b to move the sliding sleeve 301a, thereby bringing the sealing component 301 and the sealing component 303 closer together and pressing them together. The sealing component 303 then presses the sealing rubber ring 301d, improving the sealing performance between the sealing component 301 and the connecting pipe 103e, and pressing the sealing ring 303d tightly within the sealing ring groove 301f, thus further ensuring the sealing performance at the connection.

[0055] Among them, the inner circumferential surface of the rotating ring 303a is provided with an internal thread groove 303f that is threaded to the external thread ring 203c.

[0056] The remaining structure is the same as that in Example 2.
