Description

Technical Field

[0001] This utility model belongs to the field of drilling electrical equipment, specifically, it relates to a gas transmission protection device for drilling electrical equipment. Background Technology

[0002] As drilling equipment operates, the frequency of various malfunctions increases. Due to the complex working environment at drilling sites, the valve island in the electrical equipment is located in the control box and is used to control functions such as drilling rig drum clutch, rotary table inertial brake, pneumatic on / off switch, automatic feed clutch, anti-collision protection, power failure protection, and other fault protection.

Paragraph 0025 of its specification discloses: a gas generator, a compressor, a dehumidifier, a gas storage tank, a dryer, a gas guide valve, a connector, an inlet pipe, an outlet pipe, a valve island control box, and a valve island. The gas generator is connected to the compressor, the compressor is connected to the gas storage tank via the dehumidifier, the gas storage tank is connected to the dryer, the dryer is connected to the valve island control box via the connector, and the inlet pipe in the valve island control box is connected to the outlet pipe via the valve island. The valve island control box is equipped with a pressure switch and a horn. A drain port is located at the bottom of the gas storage tank.

[0004] However, in actual use, it is necessary to exhaust the air inside the valve island control box through the exhaust pipe. Since one end of the exhaust pipe does not have a cleaning structure, impurities will adhere to the inner wall of the exhaust pipe. If the impurities on the inner wall of the exhaust pipe are not cleaned in time, it will affect the efficiency of the exhaust pipe in exhausting the air inside the valve island control box.

[0005] To address these shortcomings, a gas supply protection device for drilling electrical equipment is proposed. Utility Model Content

[0033] Working principle:

[0034] First, the first annular plate 104 is threaded onto the outer wall of the air outlet pipe 101. Then, the sliding disc 113 is slid downwards. The sliding disc 113 drives the first scraper 116 and the second scraper 117 to slide into the interior of the air outlet pipe 101 via the second L-shaped rod 115. Then, the first L-shaped rod 108 is rotated. The first L-shaped rod 108 drives the second L-shaped rod 115 to rotate via the sliding disc 113. One end of the second L-shaped rod 115 drives the first scraper 116 and the second scraper 117 to rotate inside the air outlet pipe 101. The impurities attached to the inner wall of the air outlet pipe 101 are cleaned through the outer walls of the first scraper 116 and the second scraper 117, reducing the problem of impurities attached to the inner wall of the air outlet pipe 101.

[0035] The second L-shaped rod 115 is provided so that the second L-shaped rod 115 drives the first scraper 116 and the second scraper 117 to slide inside under the action of the sliding plate 113.

One end of the brush is fitted with the inner side wall of the air outlet pipe 101. A plug connector 102 is fixedly fitted on one side of the control box 100.

[0037] In this embodiment, when in use, firstly rotate the nut 118. The nut 118 moves around the first L-shaped rod 108 through the second external thread. The nut 118 drives the guide block 111 to slide inside the guide groove 109 through the sliding disc 113 and stretch the spring 112. The sliding disc 113 drives the first scraper 116 and the second scraper 117 to slide into the air outlet pipe 101 through the second L-shaped rod 115. Then rotate the first L-shaped rod 108. The first L-shaped rod 108 drives the first scraper 116 and the second scraper 117 to rotate inside the air outlet pipe 101 through the second L-shaped rod 115. The first scraper 116 and the second scraper 117 clean the impurities attached to the inner wall of the air outlet pipe 101 through one side of the first scraper 116 and the second scraper 117.

[0038] The guide groove 109 is provided so that the guide block 111 slides inside the guide groove 109 under the action of the sliding disk 113, and the guide groove 109 guides the sliding direction of the guide block 111, reducing the problem of tilting of the guide block 111 during sliding and improving the stability of the guide block 111 during sliding.
