Description

Technical Field

[0001] The invention relates to the technical field of fire pump control cabinets, and in particular to a mechanical emergency starting device of a fire pump control cabinet. Background Art

[0002] Pressure start, remote start and hard pull line start all use relays to start the pump automatically. If the relay and weak current signal fail to start the fire pump automatically, the fire pump should be started directly by the "mechanical emergency start device" set in the fire pump control cabinet. The "mechanical emergency start device" is a device that directly starts the fire pump through a mechanical interlocking device.

[0003] Patent No. CN210778284U is a device for mechanical emergency starting of a fire pump control cabinet. It adopts the design of a mechanical emergency starting device. When the electromagnetic relay fails and the water pump is started through the emergency device, the knob is turned to the right. The knob is turned to the right to drive the upper swivel seat and the lower swivel seat to swing to the left. When the lower swivel seat rotates from the vertical position to the left position, the lower swivel seat is automatically pushed to press on the first conductive ring under the action of the spring, and the water pump circuit is connected. During use, the technicians found that when the mechanical emergency starting device moves from one position state to another motion state, the movement speed is not constant, and there will be movement blockage. A larger starting force is required to overcome this movement blockage, affecting the operation. At the same time, it also causes the contact between the lower swivel seat and the second conductive ring to be an impact contact, which will generate a larger impact force and a larger noise at the moment of contact. This impact force will affect the connection strength between the second terminal and the bottom shell, forming impact damage. After multiple starting operations, the second terminal may be tilted, reducing the service life. Therefore, we propose a mechanical emergency starting device for a fire pump control cabinet.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-8 As shown, a mechanical emergency starting device of a fire pump control cabinet comprises a mounting shell 1, a guide block 2 is fixedly mounted on the upper inner side surface of the mounting shell 1, a transmission mechanism 3 is movably sleeved on the outer side of the guide block 2, the transmission mechanism 3 is horizontally arranged left and right, the lower side of the transmission mechanism 3 is transmission-connected with three balance wheels 4 which are equidistantly distributed from left to right, the right end of the right balance wheel 4 is transmission-connected with a driving device 6, the driving device 6 is movably connected to the inner side surface of the mounting shell 1 through an interlacing connection, the three balance wheels 4 are movably connected to the inner side surface of the mounting shell 1 through an axis, the lower parts of one end of the three balance wheels 4 away from the inner side surface of the mounting shell 1 are commonly transmission-connected with a starting device 5, a wire loading mechanism 7 is arranged below the starting device 5, the wire loading mechanism 7 is fixedly mounted on the inner side surface of the mounting shell 1, and the wire loading mechanism 7 is electrically connected to the starting device 5.

Turn 8 to drive the driving device 6 to rotate. During the rotation of the driving device 6, the balance wheel 4 on the right side is pushed to rotate, driving the transmission rack 33 to slide to the right, causing the slide plate 31 to slide to the right, compressing the reset spring 35, and causing the reset spring 35 to accumulate elastic potential energy (the elastic potential energy accumulated by the reset spring 35 can push the slide plate 31 to slide to the left when it is necessary to disconnect the starting device 5 and the wire loading mechanism 7, so that the balance wheel 4 is reversed and the starting device 5 and the wire loading mechanism 7 are disconnected), and at the same time drive the other two balance wheels 4 to move, so that the three balance wheels 4 make the same movement at the same time, and then drive the starting device 5 to move to the left, so that the starting device 5 is engaged with the wire loading mechanism 7, so that the left and right adjacent No. 1 wire 10 and No. 2 wire 11 are connected. The guide groove 32 is an oblong groove, and the guide block 2 is an oblong block structure, and its length is shorter than the guide groove 32. A surface sliding fit is formed between the guide groove 32 and the guide block 2, so that the slide plate 31 can make a smooth left and right linear motion.

[0032] Furthermore, the wiring mechanism 7 is used to install the No. 1 wire 10 and the No. 2 wire 11, and can cooperate with the starting device 5 to connect the No. 1 wire 10 and the No. 2 wire 11 adjacent to each other on the left and right; the wiring mechanism 7 includes a mounting plate 71 fixedly mounted on the inner side surface of the mounting shell 1, and a No. 1 limiting ring 72 and a No. 2 limiting ring 73 are fixedly mounted on the end of the mounting plate 71 away from the inner side surface of the mounting shell 1, and the No. 1 limiting ring 72 and the No. 2 limiting ring 73 are each provided with three and are alternately arranged on the left and right, and a No. 1 power board 74 and a No. 2 power board 75 are respectively fixedly clamped in the No. 1 limiting ring 72 and the No. 2 limiting ring 73, and a No. 1 power post 741 and a No. 2 power post 751 are respectively fixedly mounted on the No. 1 power board 74 and the No. 2 power board 75.

The No. 1 wire 10 and the No. 2 wire 11 are respectively located below the No. 1 power post 741 and the No. 2 power post 751 , and both extend to the outside of the mounting shell 1 .

[0033] It should be further explained that, in the wiring mechanism 7, except for the No. 1 power connection board 74 and the No. 2 power connection board 75, the No. 1 power connection post 741 and the No. 2 power connection post 751, the remaining structures are made of non-conductive materials or are coated with an insulating layer on the surface, which can play a role in preventing leakage.

[0034] Furthermore, the starting device 5 is used to connect the No. 1 wire 10 and the No. 2 wire 11. When the starting device 5 is in contact with the wire loading mechanism 7, the No. 1 wire 10 and the No. 2 wire 11 are connected. When the starting device 5 is not in contact with the wire loading mechanism 7, the No. 1 wire 10 and the No. 2 wire 11 are not connected. The starting device 5 includes a guide rod 51, which is arranged horizontally from left to right and is fixed on the mounting shell 1 by clamping. A connecting rod 52 is movably sleeved on the guide rod 51. Three slides 55 equidistantly distributed from left to right are fixedly installed on the upper end of the connecting rod 52. Three right-angle frames 53 equidistantly distributed from left to right are fixedly installed on the lower end of the connecting rod 52.

An anti-slip screw 42 is threadedly connected to the connecting column 41, and the anti-slip screw 42 contacts the slide 55. The slide 55 can slide up and down relative to the connecting column 41 and will not detach from the connecting column 41. The No. 1 clamping position 541 and the No. 2 clamping position 542 are respectively matched with the No. 1 power connection post 741 and the No. 2 power connection post 751. The surfaces used for matching on the No. 1 clamping position 541 and the No. 2 clamping position 542 are both arc-shaped surfaces, which can improve the matching stability.

[0035] It should be further explained that, in the starting device 5, the power connecting rod 54, the first clamping position 541 and the second clamping position 542 are made of conductive material in one piece, and the remaining structures are made of non-conductive material or are coated with an insulating layer on the surface to prevent leakage.

[0036] Furthermore, by rotating the driving device 6, the right-side balance wheel 4 can be driven to rotate, so that the transmission mechanism 3, the other two balance wheels 4 and the starting device 5 move; the driving device 6 includes a circular plate 61, and a driving column 68 is fixedly installed on one end of the circular plate 61 close to the inner side surface of the mounting shell 1, and the end of the driving column 68 away from the circular plate 61 movably penetrates the inner side surface of the mounting shell 1 and extends to the outer side of the mounting shell 1, and a limit knob 69 is threadedly connected to the driving column 68, and the limit knob 69 is in contact with the outer side surface of the mounting shell 1.

[0037] It should be further explained that the mechanical emergency starting device also includes a turning handle 8, which is in transmission cooperation with the end of the driving column 68 away from the circular plate 61. After the turning handle 8 is inserted into the driving column 68, the driving column 68 can be rotated by turning the turning handle 8, thereby realizing the rotation of the driving device 6.

[0038] It should be further explained that a limit block 43 is fixedly installed on the lower part of the right end surface of the right balance wheel 4, and the limit block 43 cooperates with the top rod 67; through the above arrangement, when the driving rod 62 rotates, pushing the right balance wheel 4 to rotate, driving the starting device 5 to move to the left, so that the No. 1 clamping position 541 and the No. 2 clamping position 542 are respectively in contact with the No. 1 power post 741 and the No. 2 power post 751, the driving rod 62 can no longer rotate in the original direction.
