A well clean-out device

Abstract

This utility model discloses a well cleaning operation device, characterized by comprising a support frame and a reel mounted on the support frame. The outer circumference of the reel is connected to one end of a hook structure. An anti-reverse structure, maintaining contact with the reel, is also installed on the support frame. The anti-reverse structure includes an adjusting component mounted on the support frame and a limiting component mounted on the reel. This utility model has a simple structure. By rotating the reel, the hook structure can be easily raised and lowered, thus completing the lowering and raising of the bucket. Compared with traditional methods, the operation process is simpler, the workload is significantly reduced, and the efficiency of the cleaning operation is improved. Furthermore, the anti-reverse structure design ensures that even if the operator releases the crank handle and the bucket attempts to rotate the reel in the opposite direction due to gravity, the cooperation structure of the limiting component and the adjusting component restricts the limiting component to only one rotation, effectively preventing the bucket from accidentally falling and greatly improving operational safety.

Description

Technical Field

[0001] This utility model relates to the technical field of well cleaning devices, specifically a well cleaning operation device. Background Technology

[0002] During the maintenance of municipal drainage systems, manholes, sewage wells, and other wells often accumulate large amounts of silt, stones, plastic bags, rags, and other debris due to long-term operation, seriously affecting the smooth flow and overall function of the drainage system. To ensure the normal operation of the pipe network, regularly cleaning the sediment and obstructions in the wells has become an important part of municipal maintenance work.

[0003] Currently, the dredging of municipal manholes mostly relies on manual labor combined with simple tools or sludge grab trucks. However, traditional methods have many limitations. On the one hand, sludge grab trucks are large and difficult to maneuver due to narrow streets and limited working space. Therefore, personnel need to enter the manhole for cleaning. In municipal manhole dredging operations, tools such as buckets are usually used to lift the sludge from the manhole to the ground. However, during the lifting process, there is a risk that the worker's hand may accidentally slip off the handle, causing the bucket to fall rapidly due to gravity, which could pose a serious safety threat to the workers inside the manhole. To address this, a manhole cleaning device is proposed. Utility Model Content

[0006] As a further embodiment of this utility model: a traction cylinder is sleeved on the outer circumferential surface of the reel.

[0007] As a further embodiment of this utility model: the hook structure includes a hook body and a nylon rope connected to the hook body, wherein the end of the nylon rope away from the hook body is connected to the outer peripheral surface of the traction cylinder.

[0008] As a further embodiment of this utility model: a crank handle is provided at one end of the scroll, and a friction sleeve is provided on the outer circumferential surface of the crank handle.

[0009] As a further embodiment of this utility model: the limiting member includes an annular disk sleeved on the outer circumferential surface of the scroll, and a limiting annular groove is formed on the outer circumferential surface of the annular disk, the depth of the limiting annular groove gradually decreasing from deep to shallow along the rotation direction of the scroll.

[0010] As a further embodiment of this utility model: the adjusting member includes a hollow rod, an elastic element is installed inside the hollow rod, and a telescopic rod is movably installed at the end of the hollow rod and fixedly connected to the elastic element, and the end of the telescopic rod away from the hollow rod is in contact with the limiting member.

[0011] As a further embodiment of this utility model: a vertical wall for limiting the telescopic rod is formed between one side of the limiting annular groove and the outer wall of the annular disk.

[0012] As a further embodiment of this utility model, the elastic element is a return spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This application allows for easy raising and lowering of the hook structure by rotating the reel, thus completing the lowering and raising of the bucket. Compared with traditional methods, the operation process is simpler, the workload is significantly reduced, and the efficiency of the cleaning operation is improved. In addition, the anti-reverse structure design ensures that even if the operator releases the crank and the bucket attempts to rotate the reel in the opposite direction due to gravity, the cooperation structure of the limiting and adjusting parts can limit the limiting part to only rotate one revolution, thereby effectively preventing the bucket from falling accidentally and greatly improving the safety of operation. When it is necessary to lower the bucket into the well, simply retract the adjusting part so that it is no longer in contact with the rotating part of the limiting part, and the reel can rotate freely, which is convenient for operation.

[0019] 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.

[0020] Please see Figure 1-3 In this embodiment of the utility model, a well cleaning operation device includes a support 1 and a reel 2 disposed on the support 1. The outer peripheral surface of the reel 2 is connected to one end of the hook structure 4. The support 1 is also equipped with an anti-reverse structure that keeps in contact with the reel 2. The anti-reverse structure includes an adjusting member 6 installed on the support 1 and a limiting member 5 installed on the reel 2.

[0021] Specifically, a crank handle 7 is fixedly connected to one end of the reel 2. A friction sleeve is provided on the outer circumference of the crank handle 7. This friction sleeve increases the resistance between the hand and the crank handle 7, making it easier for the worker to rotate the reel 2 using the crank handle 7. A traction cylinder 3 is fitted onto the outer circumference of the reel 2, and the traction cylinder 3 is larger than the outer diameter of the reel 2. This way, when both the reel 2 and the traction cylinder 3 rotate once, the lifting or lowering amplitude of the hook structure 4 wound on the traction cylinder 3 increases, thereby reducing the number of rotations required by the worker to turn the crank handle 7. The hook structure 4 includes a hook body 4-1 and a nylon rope 4-2 connected to the hook body 4-1. The hook body 4-1 can be used to lift devices for storing miscellaneous items in the well, such as buckets or boxes. The end of the nylon rope 4-2 furthest from the hook body 4-1 is connected to the traction cylinder 3. The outer surfaces are connected. By rotating the traction cylinder 3 in both directions, the nylon rope 4-2 can be wound around or unwound from the traction cylinder 3, thereby controlling the lifting and lowering of the hook body 4-1. In addition, when it is necessary to lower the bucket into the well, the position of the adjusting component 6 can be adjusted so that it does not contact the limiting component 5, thus enabling the free rotation of the reel 2 and ensuring that the bucket enters the well. When the bucket is full of debris, the crank handle 7 is turned to rotate the traction cylinder 3, so that the nylon rope 4-2 is wound around the traction cylinder 3, thereby transferring the debris in the well to the outside. This design ensures that even if the operator releases the crank handle 7 and the bucket attempts to drive the reel 2 to rotate in the opposite direction due to gravity, the adjusting component 6 can limit the limiting component 5 to rotate only one revolution at most, thereby preventing the bucket from falling accidentally and improving the safety of operation.

[0022] Please see Figure 2In one embodiment, preferably, the limiting member 5 includes an annular disk 5-1 sleeved on the outer circumferential surface of the scroll 2. A limiting annular groove 5-2 is formed on the outer circumferential surface of the annular disk 5-1, and the depth of the limiting annular groove 5-2 gradually decreases from deep to shallow along the rotation direction of the scroll 2. The adjusting member 6 includes a hollow rod 6-1, with an elastic member 6-3 installed inside the hollow rod 6-1. A telescopic rod 6-2, fixedly connected to the elastic member 6-3, is movably installed at the end of the hollow rod 6-1. The end of the telescopic rod 6-2 away from the hollow rod 6-1 remains in contact with the limiting member 5. A vertical wall for limiting the telescopic rod 6-2 is formed between one side of the limiting annular groove 5-2 and the outer wall of the annular disk 5-1. The elastic member 6-3 is a return spring. Further, the annular disk 5-1 is fixedly sleeved on the outer circumference of the scroll 2. On the surface, it can rotate synchronously with the scroll 2; when one end of the telescopic rod 6-2 is not squeezed by external force, the elastic element 6-3 will push the telescopic rod 6-2 back to its original length. At this time, its end can extend into the deepest position of the limiting ring groove 5-2 and contact the vertical wall of the limiting ring groove, thereby restricting the annular disk 5-1 (i.e., the scroll 2) from rotating in the opposite direction; at the same time, under the action of the elastic element 6-3, the end of the telescopic rod 6-2 can always maintain contact with the annular disk 5-1; since the elastic element has a certain elasticity, it will not affect the normal rotation of the scroll 2 while preventing reverse rotation. Through the cooperation of the telescopic rod 6-2 and the limiting ring groove 5-1 and the action of the elastic element 6-3, it can ensure the normal unidirectional rotation of the scroll 2 and effectively prevent it from rotating in the opposite direction.
