Description

Technical Field

[0001] This utility model relates to the field of underwater cleaning tools, specifically a retractable underwater obstacle removal rake. Background Technology

[0002] Hydrological monitoring systems are suitable for hydrological departments to monitor hydrological parameters of rivers, lakes, reservoirs, canals and groundwater in real time. Due to the presence of garbage and obstacles in the water, in order to reduce the impact of garbage and obstacles on monitoring, staff usually use a cleaning rake on a boat to clean up the garbage and obstacles.

[0003] The existing cleaning rakes have fixed rake lengths. Since the debris and obstacles are at different depths underwater, it takes time to replace the rakes with different lengths when cleaning debris and obstacles at deeper depths. This reduces the range of use of the cleaning rakes and decreases their efficiency in cleaning underwater debris and obstacles.

[0004] According to the announcement number CN220674419U, a leaf-clearing rake includes a connecting rod. A fixed sleeve is fixedly connected to the top of the connecting rod. Rake teeth are fixedly connected to the top of the inner side of the fixed sleeve. A rubber sleeve, a fixed ring, and a first spring are slidably connected sequentially from top to bottom to the outer side of the rake teeth. The rubber sleeve is fixedly connected to the fixed ring, and the first spring contacts the fixed ring and the fixed sleeve. A pull rope is fixedly connected to one side of the bottom end of the fixed ring, and the other end of the pull rope is fixedly connected to a sliding sleeve that slidably connects to the connecting rod. Through the combination of the locking rod, sliding sleeve, first spring, and rubber sleeve, when a large number of leaves adhere to the outer side of the rake teeth during the leaf-clearing process, pulling the locking rod compresses the sliding plate to compress the second spring. Under the restoring force of the first spring, the fixed ring drives the rubber sleeve to push away the leaves attached to the outer side of the rake teeth, thus ensuring the effective leaf-clearing of the device.

[0005] As described above, when cleaning underwater debris and obstacles, the length of the handle of the existing cleaning rake cannot be adjusted. Therefore, when cleaning debris and other obstacles at greater depths, it is necessary to spend time changing cleaning tools of different lengths to carry out the cleaning work. This reduces the scope of use of the cleaning tool and decreases the efficiency of the cleaning tool in cleaning underwater debris and obstacles. Therefore, we need to propose a telescopic underwater obstacle removal rake. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a retractable underwater obstacle removal rake, including a rake head 1 and a connecting rod 2. The rake head 1 is located at the top of the connecting rod 2. The bottom end of the rake head 1 is provided with an adjustment structure 3 for adjusting the angle of the rake head 1. The bottom end of the connecting rod 2 is provided with an adjustment groove 4. The inner cavity of the adjustment groove 4 is provided with a movable rod 5. The bottom end of the movable rod 5 is provided with a hollow tube 6. The inner cavity of the hollow tube 6 is slidably connected to the surface of the movable rod 5. The bottom end of the hollow tube 6 is provided with a moving structure 7 for adjusting the position of the movable rod 5 inside the hollow tube 6. The outer surface of the connecting rod 2 is provided with a positioning frame 8. The surface of the positioning frame 8 is provided with a movable hole 9. The inner cavity of the movable hole 9 is provided with a positioning structure 10 for positioning the position of the movable rod 5.

[0026] During adjustment, pull the movable rod 5 to adjust its position within the adjustment groove 4. Then, the positioning structure 10 positions the movable rod 5 within the adjustment groove 4. Finally, rotate the moving structure 7 at the bottom of the hollow tube 6 to push the movable rod 5 upward, thereby adjusting its position within the hollow tube 6. This allows for adjustment of the rake rod length, shortening the time required to change cleaning tools of different lengths, expanding the application range of the cleaning tools, and improving the cleaning efficiency of the cleaning tools for underwater debris.

[0027] The adjustment structure 3 includes an adjustment frame 31, which is fixedly connected to the top of the rake head 1. The surface of the adjustment frame 31 is provided with adjustment holes 32, and there are three sets of adjustment holes 32. The inner cavity of the adjustment frame 31 is rotatably connected to a connecting seat 33 through a rotating shaft. The top of the connecting seat 33 is fixedly connected to the bottom of the rake head 1. The surface of the connecting seat 33 is provided with a positioning hole 34. The adjustment hole 32 and the positioning hole 34 are bolted together by bolts and nuts. By moving the rake head 1, the angle between the rake head 1 and the adjustment frame 31 is changed through the cooperation between the connecting seat 33 and the rotating shaft, which facilitates the underwater cleaning of underwater obstacles on both sides of the cleaning tool.

[0028] The movable structure 7 includes a rotating seat 71, which is rotatably connected to the bottom end of the hollow tube 6 via a rotating shaft. A screw 72 is fixedly connected to the top end of the rotating seat. A threaded hole 73 is provided at the bottom end of the movable rod 5. The screw 72 is threadedly connected to the inner cavity of the threaded hole 73. Rotating the rotating seat 71 drives the screw 72 to rotate. The screw 72 is threadedly connected to the threaded hole 73, so that when the screw 72 rotates, it can push the movable rod 5 up and down through the threaded hole 73, thereby adjusting the position of the movable rod 5 inside the hollow tube 6.

[0029] A slider 11 is fixedly connected to the bottom end of the movable rod 5. A groove 12 adapted to the slider 11 is opened on the inner side wall of the hollow tube 6. The slider 11 and the inner cavity of the groove 12 are slidably connected. Through the cooperation of the slider 11 and the groove 12, the movable rod 5 is supported around its perimeter, preventing the movable rod 5 from rotating when the screw 72 rotates, thus improving the stability of the movable rod 5 when it moves up and down in the inner cavity of the hollow tube 6.

[0030] The positioning structure 10 includes a fixed rod 101, which slides into the inner cavity of the movable hole 9. A through hole is provided on the outer surface of the connecting rod 2, and a fixed hole 102 is provided on the outer surface of the movable rod 5. The end of the fixed rod 101 away from the movable hole 9 passes through the through hole of the connecting rod 2 and engages with the inner cavity of the fixed hole 102. After adjusting the position of the movable rod 5 in the adjustment groove 4, the fixed rod 101 is pushed through the through hole of the connecting rod 2 and engages with the fixed hole 102, so that the movable rod 5 is positioned in the inner cavity of the adjustment groove 4. Several sets of fixed holes 102 are provided, and the sets of fixed holes 102 are arranged at equal intervals on the outer surface of the movable rod 5. The setting of fixed holes 102 increases the adjustment range between the adjustment groove 4 and the movable rod 5.

[0031] A limiting block 13 is fixedly connected to the outer surface of the fixed rod 101. The limiting block 13 is located between the through hole of the connecting rod 2 and the positioning frame 8. A spring 14 is also sleeved on the outer surface of the fixed rod 101. The spring 14 is located between the limiting block 13 and the positioning frame 8. Through the cooperation of the limiting block 13 and the spring 14, during adjustment, when the finger pinches one end of the fixed rod 101 and pulls it up, the limiting block 13 will squeeze the spring 14. At the same time, the fixed rod 101 moves out of the inner cavity of the fixing hole 102 and releases the movable rod 5. After adjusting the position, the fixed rod 101 is released, and the spring 14 rebounds and pushes the limiting block 13 to reset, so that the other end of the fixed rod 101 is inserted into the inner cavity of the fixing hole 102 again to complete the positioning.

[0032] A rubber sleeve 15 is bonded to the outer surface of the hollow tube 6. The outer surface of the rubber sleeve 15 is provided with anti-slip texture. Several sets of anti-slip texture are provided. The cooperation between the rubber sleeve 15 and the anti-slip texture increases the friction effect between the worker's hand and the hollow tube 6.

[0033] A support rod 16 is fixedly connected to the inner cavity of the adjustment groove 4. A through hole is opened at the top of the movable rod 5. The support rod 16 is inserted into and slides in the inner cavity of the through hole of the movable rod 5. The stability of the movable rod 5 when sliding up and down in the adjustment groove 4 is improved by the cooperation between the support rod 16 and the through hole of the movable rod 5.

[0034] In practical use: When the length needs to be adjusted, pull one end of the fixed rod 101 to lift it, causing the limiting block 13 to compress the spring 14. At the same time, the fixed rod 101 moves out of the inner cavity of the fixed hole 102 to release the movable rod 5. Then adjust the position of the movable rod 5 in the adjusting groove 4. After adjustment, release the fixed rod 101. The spring 14 rebounds and pushes the limiting block 13 back to its original position, so that the other end of the fixed rod 101 is reinserted into the inner cavity of the fixed hole 102 to complete the positioning. Then rotate the rotating seat 71 to drive the screw 72 to rotate. Through the cooperation of the screw 72 and the threaded hole 73, the screw 72 can be rotated. 2. When rotating, the movable rod 5 moves inside the hollow tube 6, allowing the length of the rake rod to be adjusted and extended. The rake head 1 is moved through the cooperation of the connecting seat 33 and the rotating shaft, changing the angle between the rake head 1 and the adjusting frame 31. The connecting seat 33 rotates to the other end of the adjusting frame 31, and then the bolt is inserted into the adjusting hole 32 and the positioning hole 34. The bolt is then tightened with a nut to position the adjusted angle, thereby shortening the time required to change cleaning tools of different lengths, expanding the application range of the cleaning tools, and improving the cleaning efficiency of the cleaning tools for underwater debris.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
