Description

Technical Field

[0001] The invention relates to the technical field of water conservancy equipment, and in particular to a power distribution cabinet used for water conservancy equipment. Background Art

[0002] The power distribution cabinet integrates the electrical components used for power distribution. The function of the power distribution cabinet is to distribute and control the electrical equipment. When the circuit is overloaded, short-circuited or leaking, the power distribution cabinet can also provide power-off protection. Since there are many components inside the power distribution cabinet, the heat generated by the electrical components will be dissipated into the inside of the power distribution cabinet, causing the temperature to rise. Even due to the short circuit of the line, it may cause the components to spontaneously combust. Therefore, fire fighting is a very important part in the use of the power distribution cabinet.

[0003] For example, a Chinese utility model patent with authorization announcement number CN205377071U discloses a new type of distribution cabinet including a distribution cabinet body and a distribution cabinet door. A warning device is installed at the center of the top of the distribution cabinet body, and a warning light and a buzzer are installed on the top of the warning device; two groups of heat dissipation holes are symmetrically distributed on the upper part of both sides of the distribution cabinet body; wire inlets and wire outlets are evenly distributed along the length direction in the center of the bottom of the distribution cabinet body; the distribution cabinet door is installed on the front of the distribution cabinet body, and the bottom of the distribution cabinet door is on the same horizontal plane as the bottom of the distribution cabinet body; glass windows and temperature-sensitive color-changing windows are evenly distributed in the extension direction of the upper front of the distribution cabinet body; an electronic lock and a door handle are installed on the front of the distribution cabinet door; the electronic lock is installed at the edge of the front of the distribution cabinet door, and the door handle is installed above the position of the electronic lock; a lighting device is installed at the top center of the inside of the distribution cabinet body.

[0004] In view of the above-mentioned related technologies, the inventor believes that when a fire occurs inside the distribution cabinet, the open flame will burn the components and lines inside the distribution cabinet, and the generated smoke will be released to the outside through the heat dissipation holes of the new distribution cabinet, causing the entire distribution room to be filled with smoke generated by the fire. On the one hand, it will affect the line of sight of the firefighters and slow down their work progress; on the other hand, the generated smoke has certain hazards and affects the health of the staff. Summary of the invention

[0005] In order to improve the problem that smoke generated by a fire may be released to the outside through the heat dissipation holes of a distribution cabinet, the present application provides a distribution cabinet for water conservancy equipment.

[0006] The present application provides a power distribution cabinet for water conservancy equipment, which adopts the following technical solution:

[0008] By adopting the above technical solution, when a fire occurs inside the power distribution cabinet body, the driving mechanism pushes the driving inclined block to slide vertically downward, and the driving inclined block drives the control cover plate to move vertically downward. At this time, the cover plate slot of the control cover plate and the heat dissipation slot of the power distribution cabinet body are misaligned with each other, that is, the control cover plate seals the heat dissipation slot of the power distribution cabinet body, thereby achieving a closed state inside the power distribution cabinet body. While outside air cannot enter the power distribution cabinet body to assist combustion, the smoke generated by the fire inside the power distribution cabinet body cannot be released to the outside, which improves the problem that the smoke generated by the fire will be released to the outside through the heat dissipation holes of the power distribution cabinet.

At the same time, the electromagnet stops energizing, and the electromagnet no longer attracts the magnetic circular plate. The driving rod moves in a direction away from the electromagnet through the resilience of the deformed compression spring, and the driving rod drives the pressing ball to move in a direction away from the electromagnet.

[0020] By adopting the above technical solution, when the fire extinguishing compound is sprayed into the interior of the distribution cabinet body, the air pressure inside the distribution cabinet body increases, and the pressing mechanism drives the piston cylinder to move vertically upward until the interior of the exhaust pipe is connected with the interior of the distribution cabinet body, and the mixed gas inside the distribution cabinet body flows into the purification terminal through the exhaust pipe for gas purification.

[0043] The implementation principle of a power distribution cabinet for water conservancy equipment in an embodiment of the present application is as follows: when the components and lines inside the power distribution cabinet body 11 are suddenly short-circuited, a fire is likely to occur inside the power distribution cabinet body 11, thereby burning the components and lines. When a fire occurs inside the power distribution cabinet body 11, the smoke sensor 69 senses the smoke caused by the fire inside the power distribution cabinet body 11, and the smoke sensor 69 will promptly control the components and lines inside the power distribution cabinet body 11 to stop being powered on, thereby minimizing the risk of explosion caused by secondary power-on of the components and lines. At the same time, the electromagnet 33 stops being powered on, and the electromagnet 33 no longer attracts the magnetic circular plate 38. The driving rod 37 moves in a direction away from the electromagnet 33 through the resilience of the deformed compression spring 40, and the driving rod 37 drives the pressing ball 42 to move in a direction away from the electromagnet 33. The pressing ball 42 pushes the driving inclined block 29 to slide vertically downward, and the driving inclined block 29 drives the control cover plate 26 to move vertically downward. At this time, the cover plate slot 31 of the control cover plate 26 and the heat dissipation slot 13 of the power distribution cabinet body 11 are mutually misaligned, that is, the control cover plate 26 seals the heat dissipation slot 13 of the power distribution cabinet body 11, thereby realizing that the inside of the power distribution cabinet body 11 is in a closed state. While the outside air cannot enter the inside of the power distribution cabinet body 11 to support combustion, the smoke generated by the fire inside the power distribution cabinet body 11 cannot be released to the outside.

[0044] At the same time, the driving round rod 37 drives the spiral rod 61 to move in the direction away from the electromagnet 33, and the spiral rod 61 drives the spiral sleeve 64 to rotate through the spiral pattern 66, and the spiral sleeve 64 drives the rotating round rod 57 to rotate through the cooperation of the bevel gear 1 59 and the bevel gear 2 67. The rotating round rod 57 drives the steel strand 53 to wrap around the rotating round rod 57 through the limiting pulley 58, and the steel strand 53 drives the dustproof straight rod 45 to slide along the length direction of the guide straight rod 50 through the pressing straight rod 49 until the pipe through hole 44 on the surface of the fire pipe 43 is exposed. At this time, the fire extinguishing terminal is started, and the fire extinguishing compound inside the fire extinguishing terminal is sprayed out through the pipe through hole 44 of the fire pipe 43 to extinguish the fire. When the fire extinguishing compound is sprayed into the distribution cabinet body 11, the air pressure inside the distribution cabinet body 11 increases, and the mixed gas inside the distribution cabinet body 11 will fill the pressure relief airbag 21. The pressure relief airbag 21 drives the piston cylinder 16 to move vertically upward through the connecting straight rod 23 until the exhaust pipe 18 is connected to the inside of the distribution cabinet body 11. The mixed gas inside the distribution cabinet body 11 flows into the purification terminal through the exhaust pipe 18 for gas purification.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
