Description

Technical Field

[0001] The present invention relates to the field of soot blowers, and in particular to a protection device for the power cable of a soot blower. Background Art

[0002] With the continuous improvement of industrial automation, the operating efficiency and flexibility of soot blowers have become important indicators for the stable operation of power plant boilers. During the soot blowing process, the layout and management of cables and wires are particularly important. Traditionally, many power plant soot blowers require personnel to go to the work site to ensure the stable operation of the equipment. However, the flexible cable moves with the soot blower motor due to the direct tensile stress, and long-term exposure to the tensile stress will damage the insulation layer of the flexible cable. For example, the insulation layer of the flexible cable will be deformed and cracked after long-term pulling, resulting in a decrease in the insulation performance of the flexible cable. At the same time, the flexible cable is easily broken after long-term exposure to the tensile stress, leading to faults such as short circuits in the flexible cable, affecting the normal operation of the soot blower.

[0022] Embodiment 1

[0023] Referring to Figure 1 , this embodiment provides a protection device for the power cable of a soot blower, including a main body part 1, which includes a bracket 11 and a main body 12 of the soot blower carriage; a protection part 2, which includes a protection member 21 and an anti-rollover member 22 provided in the bracket 11; a traction part 3, which includes a support member 31 provided on the soot blower carriage, and a traction member 32 is provided on the support member 31; wherein, a power cable main body 121 is jointly provided in the protection member 21 and on the main body 12 of the soot blower carriage. The support member 31 drives the traction member 32 to move along with the main body 12 of the soot blower carriage. The movement of the traction member 32 can drive the protection member 21 to extend or contract. The protection member 21 protects the power cable main body 121 through telescopic movement, avoiding the tensile stress generated when the main body 12 of the soot blower carriage moves acting on the power cable main body 121.

[0024] Specifically, the power cable main body 121 is a highly flexible cable. When the main body 12 of the soot blower carriage moves, it will drive the support member 31 to move. The traction member 32 moves along with the support member 31. The protection member 21 will extend or contract under the tensile stress of the traction member 32. The tensile stress generated by the movement of the main body 12 of the soot blower carriage pulling the traction part 3 mainly acts on the protection member 21 and will not act on the power cable main body 121, thereby avoiding damage to the power cable main body 121 caused by tensile stress, effectively maintaining the stability and safety of the power cable main body 121, extending the service life of the power cable main body 121, and avoiding affecting the normal operation of the soot blower.

[0025] Embodiment 2

[0026] Referring to Figure 1 - Figure 2 , the difference between this embodiment and the first embodiment is that the protection member 21 includes a drag chain track 211 provided in the bracket 11, and a drag chain main body 212 is provided in the drag chain track 211;

[0027] Specifically, the drag chain track 211 is a customized track cleverly designed according to the spatial layout of the sootblower beam bracket 11, allowing the drag chain body 212 to freely exert its characteristics of free telescopic movement forward and backward. In order to keep the drag chain body 212 balanced during operation, the weight of the power cable body 121 must be evenly distributed. All power cable bodies 121 must be securely fixed at one end of the drag chain body 212. This ensures that the power cable body 121 can be safely moved to the other end together with other devices, namely the sootblower sports car. The drag chain body 212 is placed vertically in the drag chain track 211 as shown in the figure. The drag chain body 212 is made of recyclable, low-pollution environmentally friendly materials, and a 40mm gap is left above the drag chain body 212.

[0028] The support member 31 includes a support base 311 provided on the sootblower carriage, and two support plates 312 are provided on the support base 311; the traction member 32 includes a traction plate 321 provided on the support base 311, and a connecting plate 322 is provided on the traction plate 321 and the drag chain body 212;

[0029] Specifically, the support seat 311 is fixedly installed on the sootblower sports car by bolts, the support seat 311 is arranged in an "H" shape, the support plate 312 is fixedly connected to the support seat 311, the two support plates 312 are symmetrically arranged, the traction plate 321 is located between the two support plates 312, the traction plate 321 is in contact with the support seat 311, the support seat 311 arranged in an "H" shape can play the role of supporting the support seat 311, the traction plate 321 is fixedly connected to the support plate 312 by bolts, the connecting plate 322 is fixedly connected to the traction plate 321 by bolts, the connecting plate 322 is arranged in an "L" shape, and the connecting plate 322 is fixedly installed with one end of the drag chain body 212 by bolts;

[0030] When in use, in conjunction with Example 1, the support seat 311 will drive the support plate 312 and the traction plate 321 to move as the sootblower sports car body 12 drives the sootblower sports car body 12, and the connecting plate 322 moves with the traction plate 321. The tensile stress of the connecting plate 322 at one end of the drag chain body 212 will be extended or shortened as the connecting plate 322 is extended. At this time, the tensile stress generated by the movement of the sootblower sports car body 12 pulling the traction part 3 mainly acts on the drag chain body 212, and will not act on the power cable body 121, thereby avoiding damage to the power cable body 121 by the tensile stress, effectively maintaining the stability and safety of the power cable body 121, extending the service life of the power cable body 121, and avoiding affecting the normal operation of the sootblower;

[0031] Example 3

[0032] Reference Figure 2 - Figure 4 This embodiment is different from the second embodiment in that it further includes a monitoring member 4 provided on the bracket 11, the monitoring member 4 includes a fixing plate 41 provided on the bracket 11, and a deviation sensor 42 is provided on the fixing plate 41;

[0033] Specifically, the fixing plate 41 is fixedly connected to the bracket 11. The deviation sensor 42 is fixedly installed on the fixing plate 41 through a U-shaped bolt. The distance between the deviation sensor 42 and the drag chain body 212 is 20 mm. The deviation sensor 42 adopts an NPN-type photoelectric switch. In conjunction with Embodiment 2, when the drag chain body 212 is stretched or shortened under tensile stress, if the upper-layer drag chain body 212 deviates from the actually customized track, such as moving outward for more than a certain time, the deviation sensor 42 will act in time. If the action time exceeds 10 seconds (filtering out the passing of the intelligent soot blower trolley body 12), the DCS will intelligently judge that the signal exists and meets the time interval. At this time, it will issue a true deviation, and through the DCS system, a light word board and a picture alarm group will be generated to prompt the soot blower operation and maintenance personnel to check. The operator can timely track the situation and can take the soot blower out of operation for maintenance;

[0034] The monitoring member 4 further includes a temperature measuring thermal resistor 43 disposed in the drag chain body 212;

[0035] Specifically, when the motor power cable main body 121 on the soot blower trolley body 12 is exposed to high temperatures such as strong furnace flame high temperature and steam leakage from the sealing packing, the performance of the power cable main body 121 will decline. By using the temperature measuring thermal resistor 43 in the drag chain body 212, the heat source and adverse factors near the soot blower trolley body 12 can be well monitored. The operation and maintenance personnel can well monitor the working state of the power cable main body 121 through remote data and take means such as early intervention;

[0036] Embodiment 4

[0037] Refer to Figure 2 This embodiment is different from the second embodiment in that the anti-rollover member 22 includes an anti-rollover plate 221 disposed in the bracket 11; the anti-rollover plate 221 is welded to the bracket 11;

[0038] Specifically, the anti-rollover plate 221 is fixed to the bracket 11 by welding, which can effectively restrict the drag chain body 212 and prevent the drag chain body 212 from rolling over;

[0039] During use, when the tensile stress at one end of the drag chain body 212 is too large, under the action of the anti-rollover plate 221, the lower-layer drag chain body 212 is restricted to prevent the drag chain body 212 from rolling over;

[0040] Embodiment 5

[0041] Refer to Figure 3This embodiment differs from the fourth embodiment in that the anti-rollover member 22 includes an anti-rollover plate 221 disposed in the bracket 11, the bracket 11 is provided with a first limiting block 111 and a second limiting block 112, the anti-rollover plate 221 is provided with a fixing block 113, and the fixing block 113 is fixedly connected to the fixing plate 41 by bolts;

[0042] Specifically, the first limiting block 111 and the second limiting block 112 are fixedly connected to the bracket 11, and the first limiting block 111 and the second limiting block 112 are symmetrically arranged. There are two first limiting blocks 111 and two second limiting blocks 112, and the two first limiting blocks 111 and the two second limiting blocks 112 are symmetrically arranged. The anti-rollover plate 221 is placed between the first limiting plate and the second limiting plate. There are two fixing blocks 113, and the two fixing blocks 113 are symmetrically arranged. The two fixing blocks 113 are fixedly connected to the anti-rollover plate 221, and the fixing blocks 113 are detachably connected to the fixing plate 41 by bolts.

[0043] When in use, the anti-rollover plate 221 is placed between the first limiting block 111 and the second limiting block 112, and then the fixing block 113 is fixedly connected to the fixing plate 41 by bolts. When it is necessary to observe the lower drag chain body 212, it is only necessary to disengage the bolts from the fixing block 113 and move the anti-rollover plate 221 upwards to disengage the anti-rollover plate 221 from the first limiting block 111 and the second limiting block 112 to remove the anti-rollover plate 221. The anti-rollover plate 221 can be disassembled according to actual conditions, thereby improving practicality.

[0044] Example 6

[0045] Reference Figure 2 - Figure 3 , this embodiment is different from the second embodiment in that the protective member 21 further includes a support block 213 provided on the connecting plate 322 , and a protective pad 214 is provided on the support block 213 ;

[0046] Specifically, two support blocks 213 are provided, and both support blocks 213 are fixedly connected to the connecting plate 322 , and the protective pad 214 is fixedly connected to the support blocks 213 , and the protective pad 214 is arranged in a “C” shape;

[0047] When in use, in conjunction with Example 1, the power cable body 121 is placed on the protective pad 214, and the support block 213 can support the power cable body 121 to prevent the power cable body 121 from contacting the anti-rollover plate 221, thereby preventing the power cable body 121 from rubbing against the anti-rollover plate 221. Through the cooperation of the support block 213 and the protective pad 214, an auxiliary support and protection function is played.

[0048] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
