Description

Technical Field

[0001] The utility model relates to the field of rapping insulating shafts, in particular to a rapping insulating shaft structure. Background Art

[0002] Electrostatic precipitator is a common dust removal method in the field of industrial production. By allowing dust-laden gas to enter an electric field, the dust particles become negatively charged. Therefore, the dust particles are attracted and gathered by the positively charged anode, thereby achieving the purpose of dust removal.

[0003] The high-frequency electrostatic precipitator equipment in coastal power plants is very susceptible to water entering the insulation box due to typhoons. Rainwater passes through the insulating shaft and causes breakdown and short circuit, causing the high-frequency unit to trip and become unable to be repaired during operation, posing a major safety hazard and ultra-low emission environmental protection pressure.

[0004] The main reason for the above phenomenon is that the existing high-frequency insulation shafts of the electrostatic precipitator in the power plant are all straight. When rainwater or water vapor enters the insulation box and flows from the top to the insulation shaft, it will cause creepage breakdown, and then cause a short circuit failure of the high-frequency electrostatic precipitator equipment.

[0016] 1. By providing a second umbrella-shaped shielding part and a first umbrella-shaped shielding part at the outer end of the insulating shaft body, after the top of the insulating shaft body is stained with rainwater, if the rainwater flows downward along the insulating shaft body, the second umbrella-shaped shielding part and the first umbrella-shaped shielding part will successively block the rainwater, thereby preventing the rainwater from flowing further downward and causing creeping breakdown and short circuit;

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-5 As shown, the utility model provides a rapping insulating shaft structure, including an insulating shaft body 1, a first umbrella-shaped shielding portion 3 and a plurality of protrusions 2 are fixedly provided at the outer end of the insulating shaft body 1, a detachable sleeve 4 is sleeved at the outer end of the insulating shaft body 1, a second umbrella-shaped shielding portion 5 is fixedly provided at the outer end of the sleeve 4, and the protrusion 2 and the first umbrella-shaped shielding portion 3 are both located at the bottom of the second umbrella-shaped shielding portion 5;

[0028] A enclosure 6 is fixedly provided at the outer end of the second umbrella-shaped shielding portion 5, and a plurality of conduits 11 are fixedly provided at the bottom end of the second umbrella-shaped shielding portion 5. The top ends of the conduits 11 penetrate the second umbrella-shaped shielding portion 5. The top ends of the first umbrella-shaped shielding portion 3 and the second umbrella-shaped shielding portion 5 are both slopes. Water falling on the top ends of the first umbrella-shaped shielding portion 3 and the second umbrella-shaped shielding portion 5 will flow to the outsides of the two under the action of the slopes. The protrusions 2 are distributed both at the top and the bottom of the first umbrella-shaped shielding portion 3.

[0029] The structure is connected to the electrode of the electrostatic precipitator, and the electrode is vibrated by hitting the insulating shaft body 1, and the vibrating electrode can clean the dust attached to its surface. By providing the second umbrella-shaped shielding part 5 and the first umbrella-shaped shielding part 3 at the outer end of the insulating shaft body 1, after the top of the insulating shaft body 1 is contaminated with rainwater, if the rainwater flows downward along the insulating shaft body 1, the second umbrella-shaped shielding part 5 and the first umbrella-shaped shielding part 3 will successively block the rainwater to prevent the rainwater from flowing further downward and causing creepage breakdown and short circuit. At the same time, a plurality of protrusions 2 are fixedly provided at the outer end of the insulating shaft body 1, and the protrusions 2 can increase the creepage distance of the insulating shaft body 1, which can effectively prevent dust from adhering and gathering, thereby further preventing short circuit accidents.

[0030] A panel 6 is fixedly provided at the outer end of the second umbrella-shaped shielding portion 5. When rain falls on the top of the second umbrella-shaped shielding portion 5, the panel 6 can prevent water from dripping, so that water flows downward through the conduit 11 and is discharged, thereby preventing the insulating shaft body 1 from being affected by water dripping, thereby improving the waterproof effect of the second umbrella-shaped shielding portion 5.

[0031] When the water flowing down along the insulating shaft body 1 is small, as shown in FIG. Figure 1-3 As shown, a drainage protrusion 7 is fixedly provided at the outer end of the insulating shaft body 1, and the drainage protrusion 7 is located at the top of the sleeve 4. A first drainage channel 12 is opened at the outer end of the sleeve 4, and a second drainage channel 13 communicating with the first drainage channel 12 is opened at the top of the second umbrella-shaped shielding portion 5;

[0032] The second drainage channel 13 can guide the water flow to one of the conduits 11, and the drainage protrusion 7 can guide the water flow to the top of the first drainage channel 12, so that the water flow can be converged to facilitate unified drainage.

[0033] When the water flows downward along the insulating shaft body 1 to the drainage protrusion 7, it is blocked by the drainage protrusion 7 and cannot flow downward in a straight line, but can only flow downward in a spiral along the top of the drainage protrusion 7. Under the action of the drainage protrusion 7, the water in all directions of the outer end of the insulating shaft body 1 is concentrated, and reaches the first drainage channel 12 under the guidance of the drainage protrusion 7. Then the first drainage channel 12 guides the water to the second drainage channel 13, and finally is discharged through one of the conduits 11. In this way, a small amount of water is gathered and then discharged in a concentrated manner, avoiding the dispersion of the water flow and the expansion of its impact range.

[0034] In order to reduce the impact of vibration on the insulating shaft body 1, Figure 1 , 4 As shown, a protective component 8 is provided at the top of the insulating shaft body 1, and the protective component 8 includes a protective platform 801 sleeved on the top of the insulating shaft body 1, and a first spring 802 is fixed at the bottom of the protective platform 801. The first spring 802 is arranged at the outer end of the insulating shaft body 1, and the protective platform 801 can be disassembled and replaced.

[0035] The outer end of the insulating shaft body 1 is sleeved with a fixing ring 803, and the top end of the fixing ring 803 is fixedly connected to the bottom end of the first spring 802;

[0036] A threaded ring 804 is fixedly disposed at the bottom end of the fixing ring 803 . The threaded ring 804 is threadedly sleeved on the outer end of the insulating shaft body 1 . The threaded ring 804 can be moved up and down on the outer end of the insulating shaft body 1 by rotating the threaded ring 804 .

[0037] The protective platform 801 is sleeved on the top of the insulating shaft body 1, and the outer end of the insulating shaft body 1 is connected to the threaded ring 804 through threads. Then, the threaded ring 804 is rotated to make the threaded ring 804 move downward along the outer end of the insulating shaft body 1. The threaded ring 804 drives the fixing ring 803 and makes the first spring 802 elongated. The elastic force of the first spring 802 pulls the protective platform 801 downward, so that the protective platform 801 is fixed on the top of the insulating shaft body 1. During vibration, the protective platform 801 is vibrated instead of the insulating shaft body 1. After damage, the protective platform 801 can be disassembled and replaced, thereby improving the service life of the insulating shaft body 1.

[0038] In order to judge the wear condition of the protection platform 801, Figure 4 , 5As shown, a prompt component 9 is provided on the top of the protective platform 801. Two microholes 10 are opened on the top of the protective platform 801. The position of the microhole 10 is close to the edge of the protective platform 801. The prompt component 9 includes a spring 902 arranged on the top of the protective platform 801. The two ends of the spring 902 extend to the inside of the two microholes 10 respectively and are fixed with a reference line 901. The reference line 901 is fixed on the inner wall of the microhole 10, and the spring 902 is in a stretched state.

[0039] Connect the two ends of the spring 902 to the reference line 901 inside the microhole 10, and use the elastic force of the reference line 901 to tighten and straighten the spring 902. In the initial state, the reference line 901 is only attached to the top of the protective platform 801, and the position of the microhole 10 is close to the edge of the protective platform 801. Therefore, the position of the microhole 10 is less affected by the vibration and has less wear. The center position of the top of the protective platform 801 has greater wear. When there is a large gap between the middle part of the spring 902 and the protective platform 801, it means that the top of the protective platform 801 is severely worn and needs to be replaced in time.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
