Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and more specifically to the field of waste collection device technology suitable for confined spaces. It is applicable to scenarios where waste collection is difficult to achieve in confined spaces using other convenient methods. Background Technology

[0002] In actual production, there are many cable trenches, sewer channels, and small channels formed for other reasons. These channels are usually covered with heavy covers, and after many years of service, the covers may have become well integrated with the surrounding environment. In this case, cleaning the dirt in the narrow space usually requires a lot of manpower and resources, especially for loose dirt, and there are no tools of suitable size in the narrow space.

[0003] Patent publication number CN104044091A, entitled "A Magnetic Clamping Device," discloses the following: It includes a pair of hinged clamp handles and clamp heads; both clamp heads are disc-shaped, with threaded heads fixed vertically to the outer circular surface of each clamp head. Each threaded head is equipped with a rotatable, retractable magnetic head, which is disc-shaped. Magnetic blocks are evenly distributed in a ring within each magnetic head, with the magnetic surfaces of the magnetic blocks parallel to the clamping plane of the clamp head. The opposite magnetic surfaces of the magnetic blocks within the two corresponding magnetic heads face each other. This device is mainly used for clamping sheet-like objects. During clamping, the clamping force is constant due to magnetic force. Furthermore, by adjusting the distance between the two magnetic heads, the clamping force can be easily adjusted, minimizing the risk of damaging the object.

[0004] Patent publication number CN116572169A, entitled "A Clamping Device," discloses the following: It includes a clamping body comprising a sector-shaped portion and a clamping portion. The sector-shaped portion has toothed surfaces. The clamping body includes a first clamping body and a second clamping body, with the middle portions of the first and second clamping bodies connected by a pin. The clamping portions of the first and second clamping bodies clamp together. It also includes a drive assembly comprising a connecting shaft, on which a first gear and a second gear, arranged sequentially from top to bottom, are fixedly sleeved. The first gear meshes with the toothed surfaces of the first clamping body, and the second gear meshes with the toothed surfaces of the second clamping body. This solution synchronously drives the first and second clamping bodies to clamp or release workpieces via the first and second gears, resulting in high clamping force and high clamping accuracy.

[0005] None of the above patents are applicable to use in confined spaces. Therefore, this utility model patent provides a waste collection device that is still applicable in confined spaces. Utility Model Content

[0006] The purpose of this utility model is to provide a waste collection device suitable for confined spaces in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This utility model provides a waste collection device suitable for confined spaces, including a pliers assembly and a waste bag that cooperates with the pliers assembly;

[0009] The waste bag includes a collection bag body with an opening at one end and two traction straps on both sides of the opening of the collection bag body.

[0010] The pliers assembly includes a first clamping unit and a second clamping unit. The first clamping unit and the second clamping unit are connected by a hinge mechanism to form an X-shaped clamping member. The first clamping unit and the second clamping unit are respectively provided with a dirt strip groove that allows the corresponding traction belt to pass through.

[0011] Specifically, during operation, pliers that can open at a certain angle are used to place the waste collection bag into a confined space. After the waste is collected, it is removed using the pliers for processing. The waste-carrying groove is used to hold the traction straps at both ends of the collection bag body, thereby controlling the tightness of the collection bag body. Since the traction straps run from inside the pliers and the opening angle of the pliers is adjustable, this solution is suitable for confined spaces, such as under-grid channels, narrow trenches, and other locations where it is difficult to clean the waste.

[0012] In one embodiment, the two support columns of the X-shaped clamping member located at the rear end of the hinge mechanism are respectively connected to inwardly bent clamp handles. Each clamp handle is provided with a receiving hole inside. One end of each receiving hole is connected to the corresponding dirt strip groove, and the other end is connected to the cross section at the end of the clamp handle.

[0013] In one embodiment, each pliers handle is fitted with an adjustable pull rod through a receiving hole, and each pliers handle has a plurality of locking threaded holes that communicate with the receiving hole evenly distributed along its length. The adjustable pull rod is fixed inside the pliers handle by a locking screw passing through the locking threaded hole.

[0014] Specifically, depending on the length of the receiving hole, you can choose to rotate it out or insert it to adjust the length of the adjusting rod, thereby adjusting the length of the entire clamp handle.

[0015] During operation, the pliers, which can open at a certain angle, are used to place the waste collection bag into a small space. After the waste is collected, it is removed using the pliers for processing. The length of the pliers is adjustable, making it easy to collect waste from grooves or channels of different depths.

[0016] In one embodiment, the axis of the locking threaded hole is orthogonal to the axis of the receiving hole.

[0017] In one embodiment, the ends of the two support columns of the X-shaped clamp located at the front end of the hinge mechanism are each provided with a plier tip with an acute angle.

[0018] In one embodiment, the opening of the collection bag body is provided with a bag mouth tightening device that can tighten the opening. The bag mouth tightening device is an annular cavity provided at the opening of the collection bag body. The annular cavity has outlets on opposite sides. Each traction belt is provided in the annular cavity and its two ends leave from the corresponding outlets and are wound into a single rope and enter the corresponding waste belt trough.

[0019] Specifically, the waste collection bag should have a tightening device and, when inserted into confined spaces, allow for adjustment of the bag's tightness from outside the space to improve waste collection. The waste bag should be replaceable to ensure the overall system's sustainable use.

[0020] In one embodiment, an opening control component is provided between the inner sides of the two support columns of the X-shaped clamp located at the rear end of the hinge mechanism.

[0021] In one embodiment, the opening control component includes a secondary bending plate, with telescopic springs at both ends of the secondary bending plate, and each telescopic spring is connected to two support columns of an X-shaped clamping member located at the rear end of the hinge mechanism.

[0022] In one embodiment, the included angle of the secondary bending plate is 90°-120°.

[0023] A method of using a waste collection device suitable for confined spaces includes the following steps:

[0024] Step 1: Place a waste bag of appropriate size on the pliers assembly, and adjust the length of the pliers according to the depth of the groove or channel. Place the pliers and waste bag into the groove or channel.

[0025] Step 2: Open the clamp assembly, adjust the position of the waste, and use other tools or the lower end of the waste bag as a sieve. Depending on the width of the channel or ditch, adjust the opening of the clamp by extending and retracting the ropes at both ends of the waste bag and coordinating them to put the waste into the waste collection bag. Then close the clamp assembly.

[0026] Step 3: Remove the pliers assembly and waste bag, empty the waste, and decide whether to replace the bag based on its condition.

[0027] The beneficial effects of this utility model are as follows:

[0028] 1. This utility model has a reasonable design. It uses pliers that can open at a certain angle to put the waste collection bag into a narrow space, and then uses the pliers to remove the waste for processing after collection. The waste belt groove is used to place the traction belts at both ends of the collection bag body, thereby controlling the tightness of the collection bag body. Since the traction belts run from inside the pliers and the opening angle of the pliers is adjustable, this solution is suitable for narrow spaces, such as under the grid, narrow trenches, and other locations where it is difficult to clean the waste.

[0029] 2. The waste collection bag should have a tightening device, allowing for adjustment of the bag's tightness from outside when inserted into confined spaces, thus improving waste collection. The waste bag should be replaceable to ensure the sustainable use of the entire system. Attached Figure Description
