Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of municipal facility cleaning tools, specifically a municipal storm drain debris cleaning rake. Background Technology
[0002] In the urban infrastructure maintenance system, municipal storm drains play a crucial role in collecting and discharging rainwater. Their normal operation directly affects the smooth functioning of the urban drainage system and the prevention and control of urban flooding risks. However, with changes in the urban environment, storm drains often accumulate various debris such as fallen leaves, plastic bags, and silt. This debris not only obstructs water flow and reduces drainage efficiency but can also cause blockages, exacerbating urban flooding during heavy rains and seriously affecting the normal lives of urban residents and the safety of urban infrastructure.
[0003] Currently, the cleaning of debris from municipal storm drains largely relies on traditional tools, such as ordinary iron rakes. These tools have several limitations. Firstly, their fixed length makes them unsuitable for cleaning storm drains of varying depths. Workers often have to bend over to clean deeper drains, resulting in low efficiency and safety hazards. Secondly, the fixed angle of traditional iron rakes makes it difficult to effectively clean debris from the sides or corners of storm drains, creating blind spots and incomplete cleaning. Furthermore, existing tools lack ease of operation and structural stability, failing to meet the practical needs for efficient, convenient, and safe cleaning of municipal storm drains. Utility Model Content
[0004] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a municipal stormwater well debris cleaning rake to solve the problems of existing cleaning tools having non-adjustable length, non-adjustable rake body angle, and inconvenient operation.
[0005] The objective of this utility model can be achieved through the following technical solutions: A municipal storm drain debris cleaning rake includes: a main unit comprising a telescopic rod and a rake body disposed at the end of the telescopic rod, the telescopic rod comprising a fixed rod and an extension sleeve rod, the extension sleeve rod being sleeved on the end of the fixed rod, and a limit component being disposed between the extension sleeve rod and the fixed rod; and a steering unit disposed between the telescopic rod and the rake body, the steering unit being used to adjust and fix the angle between the rake body and the telescopic rod.
[0006] More preferably, the limiting component includes a fixed sleeve and a bracket. The fixed sleeve is disposed inside the extension sleeve rod, and the fixed sleeve and the extension sleeve rod are fixedly connected by the bracket. One end of the fixed sleeve extends into the interior of the fixed rod and is symmetrically fixedly connected to an elastic rod. A locking block is fixedly connected to the end of the elastic rod. The interior of the fixed rod is provided with a locking groove that conforms to the shape of the locking block. The locking block can be locked into the locking groove to achieve limiting.
[0007] More preferably, the limiting component further includes a trigger rod located inside the fixed sleeve. One end of the trigger rod is fixedly connected to a trigger block, the diameter of which is larger than the diameter of the trigger rod. The end of the trigger block adjacent to the trigger rod has a beveled transition area.
[0008] More preferably, one end of the trigger rod passes through the extension sleeve and extends to the outside of the extension sleeve. A button is fixedly connected to the end of the trigger rod. A return spring is sleeved on the outer surface of the trigger rod. The two ends of the return spring abut against the end of the extension sleeve and the button, respectively. When the button is pressed, the trigger block moves away from the elastic rod, causing the locking block to disengage from the slot and releasing the limiting state. The return spring is used to drive the button and the trigger rod to reset.
[0009] More preferably, the steering unit includes a connecting cylinder fixedly mounted on the rake body and a connecting disc fixedly mounted on the end of the fixed rod. A rotating shaft is fixedly connected to the side of the connecting disc near the connecting cylinder. One end of the rotating shaft extends into the interior of the connecting cylinder and is fixedly connected to a limit ring. A retaining ring is fixedly connected to the end of the connecting cylinder near the connecting disc.
[0010] More preferably, the rotating shaft passes through the retaining ring, and a limiting spring is sleeved on the rotating shaft, with both ends of the limiting spring abutting against the limiting ring and the retaining ring, respectively.
[0011] Both the connecting disc and the connecting cylinder have interlocking anti-slip textures at their closest points.
[0012] More preferably, an unlocking rod is slidably passed through the end of the connecting cylinder away from the connecting disc, one end of the unlocking rod abuts against the rotating shaft, and auxiliary latches are symmetrically arranged on the connecting cylinder.
[0013] The beneficial effects of this utility model are: 1. By setting up a telescopic rod and a limiting component, the operator can easily adjust the length of the cleaning rake according to the depth of the rainwater well, avoiding the limitations of the fixed length of traditional tools, reducing the risk of bending over to operate, and improving work efficiency. 2. The present invention allows the rake body to flexibly adjust its angle through the setting of the steering unit, which facilitates the cleaning of debris on the side walls and corners of the rainwater well, reduces cleaning dead corners, and improves the cleaning effect; 3. This utility model ensures the stability of the telescopic rod and rake body during use by using the locking block and locking groove in the limiting component, as well as the anti-slip texture and limiting spring design in the steering unit, thus avoiding the problems of accidental contraction or angle deviation.

[0019] like Figure 1-5 As shown, a municipal storm drain debris cleaning rake includes a main body unit 100 and a steering unit 200. The main body unit 100 is used to realize the basic length adjustment and raking functions of the cleaning rake, and the steering unit 200 is used to adjust the angle between the rake body 102 and the telescopic rod 101 to adapt to the cleaning needs of debris in different locations.
[0020] The main unit 100 includes a telescopic rod 101 and a rake body 102 disposed at the end of the telescopic rod 101. The telescopic rod 101 includes a fixed rod 101a and an extension sleeve 101b, the extension sleeve 101b being sleeved on the end of the fixed rod 101a, and a limit assembly 103 being disposed between the extension sleeve 101b and the fixed rod 101a.
[0021] Furthermore, the limiting component 103 includes a fixing sleeve 103a, a bracket 103b, a retaining sleeve 103a, an elastic rod 103d, a locking block 103e, a locking groove 103f, a trigger rod 103g, a trigger block 103h, a button 103i, and a reset spring 103j.
[0022] Furthermore, a fixing sleeve 103a is disposed inside the extension rod 101b, and the fixing sleeve 103a and the extension rod 101b are fixedly connected by a bracket 103b. One end of the fixing sleeve 103a extends into the interior of the fixing rod 101a and is symmetrically fixedly connected to an elastic rod 103d. A locking block 103e is fixedly connected to the end of the elastic rod 103d. The interior of the fixing rod 101a is provided with a locking groove 103f that conforms to the shape of the locking block 103e. The locking block 103e can be locked into the locking groove 103f to achieve limiting. This structure allows the extension rod 101b and the fixing rod 101a to be fixed in a suitable position, ensuring the stability of the telescopic rod during use and facilitating the cleaning of rainwater wells of different depths.
[0023] Furthermore, the trigger rod 103g is located inside the fixed sleeve 103a. One end of the trigger rod 103g is fixedly connected to a trigger block 103h. The diameter of the trigger block 103h is larger than the diameter of the trigger rod 103g. The trigger block 103h has a beveled transition area adjacent to the end of the trigger rod 103g. One end of the trigger rod 103g passes through the extension sleeve 101b and extends to the outside of the extension sleeve 101b. A button 103i is fixedly connected to the end of the trigger rod 103g. A return spring 103j is sleeved on the outer surface of the trigger rod 103g. The two ends of the return spring 103j abut against the end of the extension sleeve 101b and the button 103i, respectively. When the button 103i is pressed, the trigger block 103h moves away from the elastic rod 103d, causing the locking block 103e to disengage from the locking groove 103f, releasing the limiting state. The return spring 103j is used to drive the button 103i and the trigger rod 103g to reset. This design allows operators to easily adjust the length of the telescopic rod, improving operational convenience.
[0024] Steering unit 200 The steering unit 200 is disposed between the telescopic rod 101 and the rake body 102, and is used to adjust and fix the angle between the rake body 102 and the telescopic rod 101.
[0025] Steering unit 200 structure: Steering unit 200 includes a connecting cylinder 201 fixedly installed on rake body 102 and a connecting disc 202 fixedly installed on the end of fixed rod 101a. A rotating shaft 203 is fixedly connected to the side of connecting disc 202 near connecting cylinder 201. One end of rotating shaft 203 extends into the interior of connecting cylinder 201 and is fixedly connected to a limit ring 204. A retaining ring 205 is fixedly connected to the end of connecting cylinder 201 near connecting disc 202.
[0026] Angle Adjustment and Fixing: The rotating shaft 203 passes through the retaining ring 205, and a limiting spring 206 is sleeved on the rotating shaft 203. The two ends of the limiting spring 206 abut against the limiting ring 204 and the retaining ring 205 respectively, keeping the connecting disc 202 and the connecting cylinder 201 pressed together. The end faces of the connecting disc 202 and the connecting cylinder 201 that are close to each other are provided with mutually cooperating anti-slip textures 207. This structure allows the rake body 102 to adjust its angle within a certain range, and after adjustment, the angle is fixed by the anti-slip textures 207 and the limiting spring 206, facilitating the cleaning of debris from different locations in the rainwater well.
[0027] Furthermore, the unlocking and auxiliary structure includes an unlocking rod 208 that slides through the end of the connecting cylinder 201 away from the connecting plate 202. One end of the unlocking rod 208 abuts against the rotating shaft 203, which is used to push the rotating shaft 203 to move axially to compress the limiting spring 206. Two auxiliary latches 209 are symmetrically arranged on the connecting cylinder 201 along the axis of the unlocking rod 208, facilitating the operator to operate the unlocking rod 208 and adjust the angle.
[0028] Working principle: Based on the approximate depth of the rainwater well and the distribution of debris, the operator makes a preliminary judgment as to whether it is necessary to adjust the length of the telescopic rod and the angle of the rake body 102.
[0029] When the length of the telescopic rod needs to be adjusted, the operator presses button 103i. Button 103i moves trigger rod 103g and trigger block 103h towards fixed rod 101a. The inclined transition area of trigger block 103h contacts elastic rod 103d, causing elastic rod 103d to retract inward, thereby causing locking block 103e to disengage from slot 103f. At this time, the limit between extension sleeve 101b and fixed rod 101a is released. The operator can stretch or retract extension sleeve 101b to a suitable length according to the depth of the rainwater well, and then release button 103i. Under the action of return spring 103j, button 103i and trigger rod 103g reset, elastic rod 103d returns to its original state, and locking block 103e re-engages into the corresponding slot 103f, thus fixing extension sleeve 101b to fixed rod 101a.
[0030] When the angle of the rake body 102 needs to be adjusted, the operator holds the auxiliary lever 209 and simultaneously pushes the unlocking lever 208 towards the connecting cylinder 201. The unlocking lever 208 pushes the rotating shaft 203 axially, compressing the limit spring 206, reducing the clamping force between the connecting disc 202 and the connecting cylinder 201, and causing the anti-slip texture 207 to separate. At this time, the operator can rotate the rake body 102 to a suitable angle and then release the unlocking lever 208. Under the action of the limit spring 206, the connecting disc 202 and the connecting cylinder 201 are pressed together again, and the anti-slip texture 207 cooperates to fix the angle of the rake body 102.
