Description

Technical Field

[0001] This utility model relates to the technical field of oil tank cleaning equipment, specifically to a mud recovery mechanism for an oil tank cleaning robot. Background Technology

[0002] Tank cleaning robots are automated devices specifically designed for cleaning operations in enclosed spaces such as oil storage tanks. They are typically equipped with high-pressure water jets, rotating brushes, or scraper systems. Through remote control or autonomous navigation, they enter the interior of the tank to efficiently remove residual crude oil, sludge, and sediment from the tank walls. The sludge recovery mechanism is a key component of the cleaning robot, primarily used to collect and process the sludge mixture generated during cleaning. During operation, this mechanism extracts the sludge from the bottom of the tank through pipes, separates the oil and water, and compresses solid residues for subsequent environmental treatment or resource recycling. This achieves closed-loop management of the cleaning process and reduces environmental pollution.

[0003] Chinese Patent CN217121156U discloses an oil stain cleaning robot for cleaning sludge. The robot includes a cleaning and recovery device and a walking device connected together. The walking device drives the cleaning and recovery device to move. The cleaning and recovery device includes a frame, a sludge-pushing mechanism, and a suction pipe. The frame is connected to the walking device. The sludge-pushing mechanism includes a first driving device connected to the frame and two sludge-pushing plates movably connected to the frame. The first driving device drives the two sludge-pushing plates away from each other to remove the sludge, and also drives them closer together to push the sludge to accumulate between them. The suction pipe is connected to the frame and has a suction inlet located between the two sludge-pushing plates, and the suction pipe is used to transport the sludge. This application mainly addresses the technical problem of existing cleaning robots achieving low cleanliness levels inside oil tanks.

[0004] The mud recovery mechanism of the oil tank cleaning robot described above and under existing technology usually relies on a sludge scraper to scrape the oil sludge, and a auger to push the oil sludge to the mud pump port. The mud pump then discharges the mud to the drain pipe and out through the drain hose. The connection between the drain pipe and the drain hose at one end of the mud pump is usually fixed by clamps and bolts. During the cleaning process of the oil tank cleaning robot, the clamps and bolts are prone to vibration and loosening, which can cause the drain hose connection to loosen and break off, affecting mud recovery.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides the following two technical solutions:

[0021] Example 1: A mud recovery mechanism for an oil tank cleaning robot includes a drain pipe 1, a locking connection assembly fixedly connected to the middle of the drain pipe 1, a rigid connection pipe 3 inserted into one side of the drain pipe 1, a drain hose 4 fixedly connected to one side of the rigid connection pipe 3, and a second connection block 5 fixedly connected to the other side of the rigid connection pipe 3. An arc-shaped locking pin 6 is uniformly fixedly connected to one side of the second connection block 5 and is connected to the locking connection assembly. A protruding ring 7 is provided on one side of the drain pipe 1, and an elastic rubber sealing ring 8 is fixedly inserted into the protruding ring 7. A sealing groove 9 is provided on the inner wall of the rigid connection pipe 3, and the elastic rubber sealing ring 8 is inserted into the sealing groove 9. The arc-shaped locking pin 6 has a locking hole 10 in the middle; the locking connection assembly includes a first connecting block 201, which is fixedly connected to the drain pipe 1. An arc-shaped slot 202 is uniformly arranged on one side of the first connecting block 201, and an arc-shaped locking pin 6 is inserted into the arc-shaped slot 202. An arc-shaped sliding groove 203 is uniformly arranged on one side of the first connecting block 201, and an arc-shaped insert 204 is slidably inserted into the arc-shaped sliding groove 203. The center of the arc-shaped insert 204 is inserted through the locking hole 10. A lever 205 is fixedly connected to one side of the arc-shaped insert 204, and an auxiliary insertion hole 206 is provided on the other side of the arc-shaped insert 204.

[0022] In use, one side of the sewage pipe 1 is connected to the sludge pump, and the other side is connected to a rigid connecting pipe 3. A sewage hose 4 is fixedly connected to one side of the rigid connecting pipe 3. A first connecting block 201 on the locking connection assembly is fixedly connected to one side of the sewage pipe 1, and a second connecting block 5 is fixedly connected to one side of the rigid connecting pipe 3. Multiple sets of arc-shaped locking pins 6 are evenly fixedly connected to one side of the second connecting block 5. The connection between the arc-shaped locking pins 6 and the locking connection assembly achieves a secure and quick connection between the sewage pipe 1 and the sewage hose 4. A protruding ring 7 is provided on one side of the sewage pipe 1. An elastic rubber sealing ring 8 is fixedly inserted into one side of the protruding ring 7 using glue. When the rigid connecting pipe 3 is inserted into the sewage pipe 1, the elastic ring 8... The elastic rubber sealing ring 8 is precisely inserted into the sealing groove 9 inside the rigid connecting pipe 3, and the shape of the sealing groove 9 is consistent with that of the elastic rubber sealing ring 8, ensuring the sealing of the connection. When the drain pipe 1 is connected to the drain hose 4, the arc-shaped locking pin 6 is first aligned with the arc-shaped slot 202 on one side of the first connecting block 201. When it is inserted into place, the locking hole 10 in the middle of the arc-shaped locking pin 6 corresponds to the arc-shaped sliding grooves 203 on both sides of the arc-shaped slot 202. The lever 205 is then moved to drive the arc-shaped insert 204 to slide in the arc-shaped sliding groove 203 and penetrate into the locking hole 10, thereby locking the arc-shaped locking pin 6 in the arc-shaped slot 202 and achieving a firm connection between the drain pipe 1 and the drain hose 4.

[0023] Example 2: Based on Example 1, the first connecting block 201 is provided with an auxiliary pin groove 207 evenly arranged in a ring on one side. An auxiliary locking pin 208 is inserted into the auxiliary pin groove 207. One side of the auxiliary locking pin 208 is inserted into the auxiliary insertion hole 206. A pull cap 209 is fixedly connected to the other side of the auxiliary locking pin 208. A spring 210 is fixedly connected to one side of the pull cap 209. One side of the spring 210 is fixedly connected to the auxiliary pin groove 207.

[0024] In use, before moving the lever 205, first pull the cap 209 to cause the auxiliary locking pin 208 in the auxiliary pin groove 207 to disengage from one side of the arc-shaped slide groove 203. When the arc-shaped insert 204 is inserted into place, the auxiliary insertion hole 206 on one side of the arc-shaped insert 204 corresponds exactly to the auxiliary pin groove 207. When the cap 209 is released, under the restoring contraction action of the spring 210, the auxiliary locking pin 208 is squeezed into the auxiliary insertion hole 206, so that the lever 205 will not cause the arc-shaped insert 204 to disengage from the locking hole 10 due to accidental contact, further enhancing the reliability and firmness of the connection between the sewage pipe 1 and the sewage hose 4.
