Description

Technical Field

[0001] This invention relates to the field of dust suppression devices, and more particularly to an indoor dust suppression device for oil extraction areas. Background Technology

[0002] In oil drilling and production, various specialized equipment, such as drilling rigs, pumps, and pipelines, are required. This equipment is typically installed and maintained indoors or in designated operating rooms to ensure safe and efficient operation. To maintain a good working environment, dust suppression measures are often necessary in indoor areas. Current technologies often employ water atomization to adsorb and settle dust and debris. However, in practice, a single spray angle may prevent effective dust suppression in many areas, reducing the applicability of the device and resulting in poor dust suppression performance.

[0003] Those skilled in the art have conducted research and improvements, such as the dust suppression device for oil extraction areas proposed in application number CN202323114830.0. This technical solution uses an electric push rod to adjust the angle between the housing and the water spray pipe, and the action of the rotating rod on the connecting block improves the flexibility of the device. However, this technical solution has a limited dust suppression range during use, and the external water supply pipe prevents the housing from rotating 360 degrees, which could easily lead to pipe entanglement and limit the dust suppression effect. Therefore, we propose an indoor dust suppression device for oil extraction areas. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention has a reasonable structural design. It uses a winding wheel to wind up the traction rope, which can deflect the rectangular frame to a horizontal state. After the bidirectional reciprocating screw rotates, the dust-suppressing seat moves back and forth laterally, which can improve the dust suppression coverage. During the lateral movement, the horizontal toothed groove meshes with the spur gear to rotate the vertical support rod, which in turn makes the internal components of the transmission cavity work together. The hollow tube can drive the dust-suppressing disc to rotate. At the same time, the central shaft reciprocates and pushes the hexagonal plate. The vertical rack meshes with the spur gear ring, which makes the L-shaped tube deflect in the bearing seat, which can adjust the working position of the atomizing nozzle, improve the dust suppression range, and further improve the dust suppression effect.

[0018] 2. In this invention, the water supply hose is connected to an external water supply device, and the water level in the water tank is monitored in real time by a liquid level sensor. When the water level is lower than the lower limit of the set range, the solenoid valve can be opened to replenish water. The water flows through the diversion pipe-corrugated pipe-connector pipe-hollow pipe-spray pipe-L-shaped pipe route into the atomizing nozzle. It will not interfere with the lateral movement of the dust suppression seat or the rotation of the hollow pipe and L-shaped pipe. The structure is reasonably designed to ensure that the dust suppression work is carried out effectively.

[0019] 3. The working state of the convex frame and the locking parts in this invention is adjustable. When the device moves as a whole, the convex frame is located at the lower end of the first vertical groove and the second vertical groove, and the moving wheel can move in contact with the ground. When the device performs dust suppression work, the reverse crank handle is reversed to make the moving wheel leave the ground. The driven gear meshes with the locking parts on both sides, and the horizontal part of the L-shaped rod can be inserted into the positioning hole to lock it, preventing the top seat from sliding down due to gravity and ensuring the stability of the equipment during operation.

[0020] In summary, the present invention has a reasonable structural design, which ensures the effective dust suppression work and improves the stability of the device during operation. The atomizing nozzle deflects around the horizontal part of the L-shaped rod while rotating with the dust suppression disc, which can effectively increase the working range of atomized dust suppression and further improve the dust suppression effect.

[0048] A bidirectional reciprocating lead screw 91 is rotatably connected to the front side of the inner wall of the rectangular frame 9. A drive motor 92 is connected to the right end of the bidirectional reciprocating lead screw 91. A square rod 93 is connected to the rear side of the inner wall of the rectangular frame 9.

[0054] A vertical support rod 1121 is rotatably connected to the rear part of the inner cavity of the transmission chamber 112. A bevel gear 1122, a spur gear 1123, and a pulley 1124 are connected to the outer wall of the vertical support rod 1121. The spur gear 1123 meshes with the transverse tooth groove 94. A transmission belt 1125 is sleeved between the outer walls of the pulley 1124 and the pulley 2 1148. A side bracket 1126 is connected to the top wall of the transmission chamber 112. A transverse support rod 1127 is rotatably connected in the side bracket 1126. A bevel gear 2 1128 is connected to the left end of the transverse support rod 1127. The bevel gear 2 1128 meshes with the bevel gear 1122. A cam 1129 is connected to the right end of the transverse support rod 1127. The lower end of the cam 1129 abuts against an upper pressure block 1120.

[0055] The lower part of the hollow tube 114 is provided with multiple stroke grooves 1131. A lower pressure block 1132 is slidably connected in the stroke grooves 1131. A central shaft 1133 is connected to the bottom center of the lower pressure block 1132. A hexagonal plate 1134 is connected to the bottom of the central shaft 1133.

A pressure ring 1136 abuts against the top of the lower pressure block 1132. A synchronizing rod 1137 is connected between the outer wall of the lower pressure block 1132 and the upper pressure block 1120. A compression spring 1138 is sleeved on the upper part of the synchronizing rod 1137. A tension spring 1139 is connected between the hexagonal plate 1134 and the dust collection disc 1141.

[0056] The specific method of this embodiment is as follows:

[0057] In this embodiment, the hollow tube 114 is separated by a partition 1146, so that water flows into the hollow tube 114 and is introduced into six spray pipes 1147, and then sent out by the atomizing nozzle 1144 at the vertical end of the L-shaped tube 1143.

[0058] The bevel gear 1122 meshes with the bevel gear 1128, causing the transverse support rod 1127 to drive the cam 1129 to rotate. The cam 1129 can periodically press the upper pressure block 1120. The compression spring 1138 and the tension spring 1139 provide elastic reset. The synchronous rod 1137 can drive the lower pressure block 1132 to reciprocate up and down. When the pressure ring 1136 presses down on the lower pressure block 1132, the lower pressure block 1132 moves along the stroke groove 1131. The central shaft 1133 can drive the hexagonal plate 1134 to move. The vertical rack 1135 meshes with the spur gear ring 1145, causing the L-shaped tube 1143 to deflect in the bearing seat 1142, which can adjust the working position of the atomizing nozzle 1144.

[0059] The transmission structure causes the hollow tube 114 to rotate while the central shaft 1133 reciprocates, which enables the atomizing nozzle 1144 to deflect along with the dust collection disc 1141, thereby increasing the dust collection range and further improving the dust collection effect.

[0067] When the equipment is in operation, the reverse crank 1410 causes the moving wheel 1406 to lift off the ground. At this time, the driven shaft 1421 rotates with the bevel gear 1424, which in turn causes the driven gear 1425 to mesh with the spur racks 1464 on both sides of the transmission. The horizontal part of the L-shaped rod 1465 can extend into the positioning hole 36 along the guide port 1402. Through the synchronous pulley 1422 and the synchronous belt 1423, the components in the two accommodating cavities 1401 operate simultaneously, thereby locking the position of the positioning sleeve 35 and the linkage frame 34, preventing the top seat 6 from sliding down due to gravity, and ensuring the stability of the equipment during operation.
