Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, in particular to a fire pump control cabinet. Background Art

[0002] The fire pump is one of the core equipment in the fire protection system. Its main function is to provide sufficient water pressure and water volume when a fire occurs to ensure the effective operation of the fire extinguishing system. The fire pump control cabinet is a device used to manage and control the fire pump. It uses a series of electrical and electronic components to operate and monitor the fire pump. The fire pump control cabinet is divided into a fire hydrant control cabinet, an automatic sprinkler control cabinet, and a fire pressure regulating pump control cabinet. The fire pump control cabinet and the fire pump complement each other to ensure the efficient operation of the fire protection system.

[0003] After searching, a Chinese patent with patent announcement number CN218851148U is found, which is a fire pump control cabinet, including a cabinet body, one side of the cabinet body is open, and a cabinet door is hinged at the open position of the cabinet body by a latch, and a matching support plate is slidably installed on the side of the cabinet body away from the cabinet door, and two symmetrical support frames are fixedly installed on the side of the support plate close to the cabinet body, and the support frames are slidably fitted with the inner wall of the cabinet body, and multiple groups of cross bars of the two support frames are fixedly installed with multiple support bars distributed in an array, and a U-shaped frame is fixedly installed on the side wall of the support plate, and the left and right sides of the U-shaped frame are respectively fixedly fitted with adjacent support frames, and a hollow box for placing lime bags is fixedly installed between the left and right sides of the cabinet body.

[0004] Although the above patent can isolate and place the fire pump control components, the above patent still has the following problems in actual application:

[0005] 1. Lack of flexibility: The height of the multiple support bars distributed in an array for carrying electrical and electronic components in the control cabinet is fixed and cannot be adjusted freely, resulting in low space utilization for electrical and electronic components of different sizes. Smaller or lower components will waste a lot of space, while larger or higher components may be difficult to place reasonably due to lack of extra space.

[0006] 2. Poor heat dissipation effect: The heat dissipation method of the above patent is mainly to draw air from the bottom of the cabinet into the cabinet through a fan, and exhaust hot air through the shutters on the top. It is difficult to ensure that the cold air is evenly distributed to the placement space where each electrical and electronic component is located, and the heat dissipation effect is insufficient and poor because the heat is only dissipated by blowing air.

The lifting deck 7 is used to carry electrical and electronic components, and the left and right sides of the lifting deck 7 are rotatably connected with swing members 91 through a rotating shaft, and the swing member 91 is composed of a hollow round rod and a square, and the square is connected to the middle of the bottom of the hollow round rod, and the hollow round rod is connected to the rotating shaft of the lifting deck 7, and the swing member 91 Two blocks 9 are symmetrically connected to the bottom of the hollow round rod, and the shape of the block 9 is L-shaped. The guide rail 8 is spaced along its height extension direction with slots 81 matching the blocks 9. The side of the slot 81 is designed as an inclined surface, and the side of the block 9 facing the slot 81 on the same side is designed as an inclined surface. A driving component is provided on the lifting deck 7, and the driving component is used to drive the block 9 to insert into the slot 81 to lock the lifting deck 7, and to drive the block 9 to move out of the slot 81 to release the lock of the lifting deck 7. The driving component includes a shaft turntable 11 rotatably connected to the middle of the front side of the lifting deck 7, and the left and right blocks 9 on the front side are both hinged with connecting rods 10, and the connecting rods 10 are hinged to the turntable of the shaft turntable 11. At the eccentric position at the bottom, a positioning spring 12 is connected between the block of the swing member 91 and the lifting deck 7, an air-cooled radiator 3 is installed on the top of the control cabinet 1, and four air inlet ducts 4 for blowing air into it are installed at intervals on the rear side of the control cabinet 1 along its height extension direction, and the air-cooled radiator 3 is connected to the air inlet duct 4 through an air delivery pipe 31, and an air outlet window 5 located below the lowermost air inlet duct 4 is installed on the rear side of the control cabinet 1. Two front and rear resistance heating wires 6 are installed at intervals in the air-cooled radiator 3, and a water-cooled unit for water-cooling and heat dissipation is provided on the lifting deck 7, and the water-cooled unit includes a cooling circulation box 13, a liquid inlet pipe 14, a reflux pipe 15, a connecting pipe 16 and a cooling pipe 18, and the lifting deck 7 is provided with a water-cooled unit for water-cooling and heat dissipation. The water-cooled unit includes a cooling circulation box 13, a liquid inlet pipe 14, a reflux pipe 15, a connecting pipe 16 and a cooling pipe 18. An installation groove is provided on the deck 7, in which an S-shaped cooling pipe 18 is installed. The two upper and lower adjacent cooling pipes 18 are connected by a retractable connecting pipe 16, and the connecting pipe 16 is located on the rear side of the lifting deck 7. A cooling circulation box 13 is installed at the bottom of the inner side of the control cabinet 1. The cooling circulation box 13 is connected to the lowermost cooling pipe 18 through a retractable liquid inlet pipe 14, and the cooling circulation box 13 is connected to the uppermost cooling pipe 18 through a retractable return pipe 15. Heat absorbing grid plates 17 are installed at intervals on the lifting deck 7 along its length extension direction, and the S-shaped cooling pipe 18 passes through the heat absorbing grid plate 17. The heat absorbing grid plate 17 is made of copper, and the copper heat absorbing grid plate 17 has a good heat absorption effect.

[0028] Before placing the electrical and electronic components on the lifting deck 7, the height of the lifting deck 7 is adjusted according to the size of the electrical and electronic components. If the lifting deck 7 is to be raised, the lifting deck 7 is directly moved upward, thereby driving the block 9 to move upward. When the block 9 moves upward, the inclined surface on the side of the slot 81 pushes the inclined surface on the side of the block 9, so that the block 9 is rotated out of the slot 81. Since the block 9 moves upward and is separated from the plane at the bottom of the slot 81, the block 9 can be smoothly rotated out of the slot 81. The rotation of the block 9 drives the shaft turntable 11 to rotate through the connecting rod 10. When the block 9 rotates out of the slot 81, it drives the swing member 91 to rotate, compressing the positioning spring 12. When the block 9 moves up to align with the last slot 81, the swing member 91 is pushed to reverse and reset under the reset action of the positioning spring 12, thereby driving the block 9 to reverse and insert into the slot 81, and then locking the lifting deck 7. In this way, the lifting deck 7 can be directly moved up to raise the lifting deck 7, which is convenient and quick to operate. The block 9 reverses and pulls the shaft turntable 11 to reverse through the connecting rod 10. If the lifting deck 7 is to be lowered, the lifting deck 7 is first slightly moved up to drive the block 9 to move up and separate from the plane at the bottom of the slot 81, and then the shaft turntable 11 is rotated. The shaft turntable 11 rotates and pulls the left and right blocks 9 on the front side out of the slot 81 through the connecting rod 10. The front block 9 rotates and drives the rear block 9 out of the slot 81 through the swing member 91, releasing the lock on the lifting deck 7, and the positioning spring 12 is compressed accordingly. Then, the lifting deck 7 is moved downward, the shaft turntable 11 is released, and the swinging member 91 is pushed to reverse and reset under the reset action of the positioning spring 12, thereby driving the clamping block 9 to reverse and insert into the clamping slot 81 to lock the lifting deck 7. In this way, the device realizes flexible adjustment of the placement space by adopting the lifting deck 7 whose height can be freely adjusted to adapt to electrical and electronic components of different sizes, and can reasonably place electrical and electronic components of various sizes, thereby improving space utilization.

[0029] The air-cooled radiator 3 is controlled to work, and the external cold air can be input into the air delivery pipe 31. Through the four air inlet ducts 4 arranged at intervals from top to bottom, the cold air can be evenly dispersed to the placement spaces where the electrical and electronic components are located, so that the electrical and electronic components in each placement space can be evenly cooled, thereby improving the heat dissipation effect. The hot air in the control cabinet 1 is discharged from the air outlet window 5. In a humid environment, such as rainy days or the return of the south wind, the humidity in the air is high, and the control resistance heating wire 6 is controlled to work to heat and dehumidify the air, thereby reducing the relative humidity and preventing the electrical and electronic components from being corroded or otherwise damaged due to excessive humidity. The heat absorbing grid plate 17 can absorb the heat on the lifting deck 7 and the electrical and electronic components, further improving the heat dissipation effect. By controlling the operation of the cooling circulation box 13, the coolant can be injected into the cooling tube 18 at the bottom through the liquid inlet pipe 14, and the liquid inlet pipe 14 is transported to the remaining cooling tubes 18 through the connecting pipe 16. The coolant in the uppermost cooling tube 18 is transported back to the cooling circulation box 13 for cooling through the return pipe 15, so that the coolant circulates in the cooling tube 18, thereby realizing water cooling of the lifting deck 7 and the heat absorbing grid plate 17, taking away the heat on the lifting deck 7 and the heat absorbing grid plate 17, and further improving the heat dissipation effect. In this way, the device can not only uniformly air cool the lifting deck 7 and the electrical and electronic components thereon, but also uniformly water cool the lifting deck 7 and the electrical and electronic components thereon, and the heat dissipation effect is good.

[0030] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
