Description

Technical Field

[0001] This utility model belongs to the field of building cable trench cleaning technology, specifically relating to a concrete slag cleaning device for cable trenches in sewage treatment construction projects. Background Technology

[0002] After concrete pouring, concrete debris accumulates in the cable trenches of wastewater treatment plants. This debris may contain sharp stones or hardened lumps. If not cleaned properly, it can scratch or abrade the cable insulation during cable laying, affecting its proper alignment and bending radius, and even puncture the cable sheath, leading to leakage or short circuit risks. Furthermore, the debris covering the cable surface hinders heat dissipation, causing localized overheating, accelerating cable aging, and potentially leading to insulation failure or fire. The current solution is to use a blower to remove the concrete debris after the cable trench has been poured.

[0003] However, existing blowers mostly rely on high-pressure airflow (such as air compressor drive) to clean debris, but they are not very effective for stubborn concrete debris. Especially when the debris is tightly adhered to the side wall of the cable trench, the airflow is difficult to completely remove it, and secondary treatment is required for stubborn residue. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a concrete slag cleaning device for cable trenches in sewage treatment construction projects, so as to solve the problems mentioned in the prior art.

[0005] The technical solution adopted by this utility model is a concrete slag cleaning device for cable trenches in sewage treatment construction projects, comprising: A lithium-ion battery hair dryer, comprising a lithium-ion battery pack and a hair dryer, both of which are fixed with a shoulder strap and connected by a cable. The hair dryer comprises a hair dryer body and a blower tube, the blower tube being fixedly connected to the air outlet of the hair dryer body. The crushing assembly includes a first support plate, a second support plate, threaded holes, a support tube, a cylinder, a piston rod, a carbide tip, and an air pipe. One end of the first and second support plates is fixedly connected to the side of the blower body. Threaded holes are respectively opened on the first and second support plates. One end of the support tube is spirally connected to the threaded hole of the second support plate. The cylinder seat is fixedly connected to the other end of the support tube. The cylinder is a double-acting cylinder. The carbide tip is fixedly connected to the piston rod end of the cylinder. There are two air pipes. One end is fixedly connected to the cylinder, and the other end passes through the threaded hole of the first support plate and is connected to the miniature air pump inside the blower body.

[0006] Furthermore, when the crushing component is in use, the other end of the support tube away from the cylinder is spirally connected to the threaded hole of the second support plate; when not in use, the other end of the support tube away from the cylinder is spirally connected to the threaded hole of the first support plate.

[0007] Furthermore, the hair dryer also includes a handle, which is fixedly connected to the upper end of the hair dryer body, and a control button for starting the hair dryer is fixedly connected to the upper end of the handle.

[0008] Furthermore, it also includes a support assembly, which includes a first connecting ring, a connecting rod, and a second connecting ring. The first connecting ring is sleeved on the blower tube, one end of the connecting rod is fixedly connected to the side of the first connecting ring, and the second connecting ring is fixedly connected to the other end of the connecting rod.

[0009] Furthermore, the first connecting ring is fastened to the blower pipe by a locking rod, and the inner diameter of the second connecting ring is slightly larger than the outer diameter of the support pipe.

[0010] Compared with the prior art, the beneficial effect of this utility model is that, through the set crushing component, when encountering stubborn concrete debris in the cable trough, the support tube is rotated, and one end of it is rotated through the threaded hole of the first support plate, pushing the support tube, and then turning one end of the support tube into the threaded hole of the second support plate. At this time, the cylinder, piston rod and hard alloy tip extend out of the front end of the blow pipe. Pressing the start button on the handle starts the cylinder, and the air pump provides air pressure to the cylinder through the air pipe, driving the piston rod to move back and forth, thereby driving the hard alloy tip to move and impact the stubborn concrete debris. This setting can clean stubborn concrete debris, avoid secondary labor, and facilitate the cleaning of stubborn residue. Attached Figure Description

[0013] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0014] Example 1: As Figure 1-3 As shown, a concrete slag cleaning device for cable trenches in sewage treatment construction projects includes a lithium-ion blower and a crushing component. The lithium-ion blower includes a lithium-ion battery pack 10 and a blower. Both the lithium-ion battery pack 10 and the blower are fixed with a shoulder strap and are connected by a cable. The blower includes a blower body 11 and a blower pipe 13, with the blower pipe 13 fixedly connected to the air outlet of the blower body 11. The blower also includes a handle 12, which is fixedly connected to the upper end of the blower body 11, and a control button for starting the blower is fixedly connected to the upper end of the handle 12. The blower body 11 is internally equipped with a compressed air tank, a micro air pump, and a filter and protection structure. The lithium-ion battery pack 10 provides power to the blower and the crushing component. The blower body 11 is used to output high-pressure airflow. The handle 12 facilitates holding the blower body 11, and the blower pipe 13 is used for airflow guidance.

[0015] The crushing assembly includes a first support plate 20, a second support plate 21, a threaded hole 22, a support tube 23, a cylinder 24, a piston rod 25, a carbide tip 26, and an air pipe 27. One end of the first support plate 20 and the second support plate 21 are fixedly connected to the side of the blower body 11. The threaded holes 22 are respectively opened on the first support plate 20 and the second support plate 21. One end of the support tube 23 is spirally connected to the threaded hole 22 of the second support plate 21. The cylinder 24 is fixedly connected to the other end of the support tube 23. The cylinder 24 is a double-acting cylinder. The carbide tip 26 is fixedly connected to the end of the piston rod 25 of the cylinder 24. One end of the air pipe 27 is fixedly connected to the cylinder 24, and the other end passes through the threaded hole 22 of the first support plate 20 and is connected to the micro air pump inside the blower body 11. The air inlet of the micro air pump is connected to the outside through a pipe. The thrust generated when the rodless chamber of a double-acting cylinder is inlet is greater than that generated when the rod chamber is inlet (the force pushing the piston rod out is greater than the force pulling it back), which needs to be considered in the pneumatic circuit design. The two air pipes of the double-acting cylinder are connected to a two-position three-way valve for control. When one side is inlet, the other side is connected to the outside via the two-position three-way valve; when the other side is inlet, that side is connected to the outside. This enables the reciprocating motion of the piston rod and impacts the bonded concrete.

[0016] When the crushing assembly is in use, the other end of the support tube 23 away from the cylinder 24 is spirally connected to the threaded hole 22 of the second support plate 21. When not in use, the other end of the support tube 23 away from the cylinder 24 is spirally connected to the threaded hole 22 of the first support plate 20. Two tracheas 27 are used, which pass through the threaded holes 22 of the first support plate 20 and the second support plate 21 in sequence, and through the support tube 23. The first support plate 20 and the second support plate 21 provide support, the threaded hole 22 provides fixing, the support tube 23 provides support and protection, the double-acting cylinder 24 provides reciprocating power, the piston rod 25 is used to reciprocate to transmit power, the carbide tip 26 is used to crush stubborn concrete slag, and the start button of the crushing component is integrated on the control button on the handle 12.

[0017] Working principle: When encountering stubborn concrete debris in the cable trough, rotate the support tube 23, turning one end of it through the threaded hole 22 of the first support plate 20, pushing the support tube 23, and then turning one end of the support tube 23 into the threaded hole 22 of the second support plate 21. At this time, the cylinder 24, piston rod 25 and hard alloy tip 26 extend out of the front end of the blower pipe 13. Press the start button on the handle 12 to start the cylinder 24. The air pump provides air pressure to the cylinder 24 through the air pipe 27, driving the piston rod 25 to move back and forth, thereby driving the hard alloy tip 26 to move and impact the stubborn concrete debris.

[0018] This step can remove stubborn concrete debris, avoiding the need for secondary labor.

[0019] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes: The support assembly includes a first connecting ring 30, a connecting rod 31, and a second connecting ring 32. The first connecting ring 30 is sleeved on the blower tube 13, one end of the connecting rod 31 is fixedly connected to the side of the first connecting ring 30, and the second connecting ring 32 is fixedly connected to the other end of the connecting rod 31. The first connecting ring 30 is fastened to the blower pipe 13 by a locking rod, and the inner diameter of the second connecting ring 32 is slightly larger than the outer diameter of the support pipe 23. The first connecting ring 30 and the connecting rod 31 serve a connecting function, while the second connecting ring 32 serves a supporting function.

[0020] Working principle: Place the second connecting ring 32 onto the support tube 23, and then place the first connecting ring 30 onto the blower tube 13. Tighten the locking rod on the first connecting ring 30 to secure the first connecting ring 30 to the blower tube 13. In use, turn one end of the support tube 23 out of the threaded hole 22 of the first support plate 20, push the support tube 23 to move along the second connecting ring 32, screw one end of the support tube 23 into the threaded hole 22 of the second support plate 21, and press the control button on the handle 12 to start the crushing assembly.

[0021] This step can improve the stability of the crushing components during use.
