Description

Technical Field

[0001] This utility model belongs to the field of sewer debris cleaning technology, specifically relating to a portable sewer debris grabber. Background Technology

[0002] In the daily operation of homes, restaurants, and small commercial spaces, sewer blockages caused by the accumulation of debris such as hair, food scraps, and fibrous fibers are extremely common. These blockages not only hinder drainage but also easily breed bacteria and produce odors, seriously affecting the living and usage environment. If not cleaned promptly, they can lead to more serious pipe malfunctions such as corrosion and rupture, increasing repair costs and difficulty. Therefore, manual debris-removing tools are typically used to remove and clean debris from sewers.

[0003] Existing manual debris-grabbing tools are mostly rod-shaped with grippers at the front. The grippers open and close by pressing the handle, which drives a linkage mechanism to grab debris from pipes. However, these manual tools require continuous gripping force to maintain the grippers closed. For elderly people, women, and other users with weaker strength, prolonged use can easily lead to hand fatigue. It is also difficult to ensure the grippers hold the debris firmly, and the debris can easily fall off during the grabbing process. Furthermore, the opening and closing angle and force of the grippers are entirely dependent on manual control, making it difficult to accurately adapt to debris of different sizes and shapes. Especially for debris deep in pipes or in narrow areas, manually adjusting the position and opening of the grippers is extremely difficult, easily resulting in problems such as "not being able to grab" or "not being able to grip firmly". Utility Model Content

[0004] The purpose of this invention is to provide a portable sewer debris grabber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable sewer debris grabber, comprising:

[0006] The handle portion has a waterproof sleeve on one side and a spring sleeve connecting the waterproof sleeve to the handle portion.

[0007] A gripping assembly, located at one end of a waterproof sleeve, is used to grip debris in the sewer. The gripping assembly includes a fixed base and an electric push rod. The fixed base is connected to one end of the waterproof sleeve, and several grippers are hinged to one end of the fixed base. The electric push rod is installed inside the waterproof sleeve via a mounting bracket. The push rod extends and retracts, causing the grippers to open and close around the hinge point. When the push rod extends, it can open the grippers to grab the debris, and when the push rod retracts, it pulls the grippers to close and clamp the debris, thus completing the gripping operation.

[0008] Preferably, the fixed base has several hinge seats connected in a circular pattern, and one end of the gripper is connected to a worm gear, which is hinged to the hinge seat through a pin, providing stable hinge support for the gripper. Through the cooperation of the hinge seat, worm gear and pin, the gripper can rotate smoothly around the hinge point, ensuring the basic stability of the gripper's opening and closing action.

[0009] Preferably, the fixed base has a slot in the middle and a worm gear is slidably connected in the slot and the worm gear meshes with a worm wheel. The push rod of the electric push rod is connected to one end of the worm gear to form a transmission structure. The linear extension and retraction motion of the electric push rod is converted into the rotational opening and closing motion of the gripper through the meshing of the worm gear and the worm wheel, ensuring that the opening and closing angle of the gripper is precise and controllable.

[0010] Preferably, one end of the gripper is connected to a clamping block with several teeth, which enhances the gripping force between the gripper and the debris. The clamping block expands the contact area, and the teeth embed into the surface of the debris, reducing the risk of the debris falling off during the gripping process.

[0011] Preferably, the inner surface of the gripper is connected with several protrusions to adapt to irregularly shaped debris. The protrusions fit the contour of the debris and increase friction, further improving the gripper's clamping effect on different types of debris.

[0012] Preferably, a protective sleeve is fixedly fitted at the connection between the spring sleeve, the waterproof sleeve, and the handle to seal the gap at the connection and prevent sewage and silt from seeping into the equipment and damaging the components.

[0013] Preferably, the gripper has a slot inside to reduce structural weight. This reduces weight while ensuring the gripper's structural strength, making the device easier to operate, store, and carry, thus improving portability.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The electric push rod is the core power source and can automatically complete the opening and closing action of the gripper. Users only need to control the start and stop of the device and the direction of penetration through the handle. There is no need to manually exert force to clamp. This not only avoids hand soreness and fatigue after use, but also eliminates the hidden danger of "insufficient manual force causing the gripper to loosen". It can easily control the gripper to clamp the debris stably.

[0016] (2) The end of the gripper is equipped with a clamping block with teeth evenly distributed on the surface of the clamping block. At the same time, several protrusions are connected to the inner surface of the gripper. When the gripper picks up the debris and closes, the teeth can embed into the surface of the debris (such as hair clumps or fiber fragments), and the protrusions can conform to the contour of irregular debris (such as lumpy food residue), greatly enhancing the friction between the gripper and the debris, and can firmly clamp it, further reducing the risk of falling off.

[0017] (3) The equipment is lightweight and the gripper is further reduced in weight through the hollow groove design. Users can easily hold and operate it with one hand without having to carry it. At the same time, the various parts of the equipment (handle, spring sleeve, waterproof sleeve, gripper) are linearly connected, and the overall size is compact. When storing, it can be directly put into a home storage cabinet, drawer or tool box in a catering establishment without taking up too much space and is more convenient to use.

[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] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] This utility model provides, for example Figure 1-5A portable sewer debris grabber shown includes:

[0027] The handle 1 serves as the operation control center, housing a control module and a power supply module for triggering the action of the power components, enabling precise control of the gripping action. A waterproof sleeve 2 is provided on one side of the handle 1, which is used to seal and protect the internal transmission and power components, isolating them from sewage, silt, and corrosive substances in the sewer, preventing damage to the components and extending the service life of the equipment. A spring sleeve 3 is connected between the waterproof sleeve 2 and the handle 1. The spring sleeve 3 combines flexibility and structural support, and can be flexibly bent according to the direction of the sewer pipe, adapting to different angles, depths, and irregular pipe scenarios. At the same time, it can transmit operating force to adjust the position of the gripping components, solving the problem that traditional straight rod tools cannot penetrate into complex pipes.

[0028] The gripping component, located at one end of the waterproof sleeve 2, has the core function of stably gripping debris of different sizes and shapes in the sewer, such as hair clumps, food scraps, and fiber fragments. The gripping component includes a fixed base 4 and an electric push rod 5. The fixed base 4 is connected to one end of the waterproof sleeve 2, serving as the mounting and support foundation for the gripping component and ensuring coordinated operation of all components. Several grippers 6 are hinged to one end of the fixed base 4. The electric push rod 5 is installed inside the waterproof sleeve 2 via a mounting bracket, serving as a power output source and replacing manual application. The force is transmitted through the extension and retraction of the push rod of the electric push rod 5, converting electrical energy into mechanical force and transmitting it to the gripper 6. This causes several grippers 6 to open and close precisely around the hinge point. Specifically, when the push rod extends, it can cause the gripper 6 to open to an angle suitable for the size of the debris, so as to grab debris deep inside the pipe or in narrow areas; when the push rod retracts, it pulls the gripper 6 to close, forming a stable clamping force to fix the debris, preventing the debris from falling off during the grabbing process, completing an efficient grabbing operation, and solving the problems of traditional manual tools requiring continuous force, insufficient clamping force, and high operation difficulty.

[0029] The fixed base 4 is circumferentially connected with several hinge seats 7. The hinge seats 7 serve as the hinge fulcrum of the gripper 6, providing stable rotational support for the gripper 6. This ensures that multiple grippers 6 open and close synchronously and move with precise trajectories, avoiding problems such as gripper 6 shifting or failing to align with debris due to unstable support. One end of the gripper 6 is connected to a worm gear 8. The worm gear 8 serves as a transmission intermediate, receiving power and converting it into the rotational motion of the gripper 6. The worm gear 8 is hinged to the hinge seats 7 via a pin 15. The pin 15 has high strength and wear-resistant properties, ensuring smooth and uninterrupted rotation of the worm gear 8 and the gripper 6 around the hinge seats 7, reducing component wear and extending the service life of the transmission structure.

[0030] The fixed base 4 has a slot in the middle. The function of the slot is to limit the movement direction of the worm 9, ensuring that the worm 9 slides only in a straight line along the axis of the waterproof sleeve 2, thus preventing the worm 9 from deviating and causing transmission failure. The worm 9 is slidably connected in the slot and meshes with the worm wheel 8. Through the tooth meshing transmission between the worm 9 and the worm wheel 8, the linear motion of the electric push rod 5 can be accurately converted into the circular motion of the worm wheel 8, thereby driving the gripper 6 to open and close evenly. This ensures that the opening and closing angles of each gripper 6 are consistent, adapting to the gripping needs of different sized objects and solving the problem of uneven opening and closing angles and difficulty in adapting to objects in traditional manual tools. The push rod of the electric push rod 5 is connected to one end of the worm 9 to realize the direct transmission of power, ensuring low power loss, rapid transmission response, and improving the timeliness and stability of the gripping action.

[0031] One end of the gripper 6 is connected to a clamping block 10. The clamping block 10 is used to increase the contact area between the gripper 6 and the debris, and to distribute the clamping force to prevent the debris from being damaged or slipping due to excessive local force. At the same time, it can adapt to the gripping of irregularly shaped debris. The clamping block 10 is provided with several teeth 11. The teeth 11 can enhance the friction between the clamping block 10 and the surface of the debris. Especially for smooth and slippery debris such as wet and slippery food residue and plastic fragments, it can effectively prevent the debris from falling off during the gripping process, improve the gripping success rate, and solve the problem of insufficient friction between the gripper and the debris in traditional tools.

[0032] The inner surface of the gripper 6 is connected with several protrusions 12. The protrusions 12 serve as friction-enhancing auxiliary structures, which can further improve the contact friction between the inner surface of the gripper 6 and the debris. At the same time, they can fill the gaps on the surface of the debris, so that the gripper 6 can form a tighter wrapping clamp on irregular debris such as fiber clumps and debris with protrusions, preventing the debris from shifting during the gripping process. This compensates for the shortcomings of the teeth 11 of the clamping block 10 in gripping small and loose debris, and achieves stable gripping of various types of debris.

[0033] A protective sleeve 14 is fixedly fitted at the connection between the spring sleeve 3, the waterproof sleeve 2, and the handle part 1. The protective sleeve 14 has a dual function of sealing and buffering. It can seal the gaps at the connection to prevent sewage and silt from seeping into the equipment through the gaps, protect the wires and connecting parts inside the stainless steel spring sleeve 3, and prevent corrosion or short circuits. At the same time, it can improve the comfort of holding the handle part 1, extend the overall service life of the equipment, and solve the problems of easy wear and leakage at the connection of traditional tools.

[0034] The gripper 6 has a slot 13 inside to reduce the structural weight. The slot 13 achieves a lightweight design of the gripper 6 while ensuring the structural strength of the gripper 6 and ensuring that the clamping force meets the gripping requirements. On the one hand, it can reduce the overall weight of the equipment and reduce the burden on the user's hands. On the other hand, it can improve the portability of the gripper 6, making it convenient to store and carry the equipment. At the same time, it avoids the problem of difficulty in controlling the position when the gripper is too heavy and is inserted into the pipe.

[0035] This portable sewer debris grabber features a three-section structure: the handle 1 serves as the operating center, housing control buttons and a circuit module; the middle spring sleeve 3 connects the handle to the front actuator, providing both flexibility and support; and the front waterproof sleeve 2 protects the internal transmission components. When the user presses the control button on the handle 1, the circuit module sends an electrical signal to the electric push rod 5 inside the waterproof sleeve 2, activating the power output. The control button employs a double interlock design, allowing different buttons to control the extension and retraction of the electric push rod 5, preventing accidental movement conflicts. The end of the electric push rod 5 is directly connected to a worm gear 9, which is constrained by a fixed base. Within the slot of 4, sliding is only possible along the axis of the waterproof sleeve 2. Multiple hinge seats 7 are evenly distributed around the circumference of the fixed seat 4. Each hinge seat 7 is connected to a gripper 6 via a pin 15. The connection between the gripper 6 and the hinge seat 7 is provided with worm gear 8 teeth, and all worm gears 8 are engaged with the worm 9. When the push rod of the electric push rod 5 extends and pushes the worm 9 to slide forward, the helical teeth of the worm 9 will drive the worm gear 8 to rotate around the pin 15, thereby causing the gripper 6 to open outward. Conversely, when the push rod of the electric push rod 5 retracts and pulls the worm 9 to slide backward, the worm gear 8 rotates in the opposite direction, and the gripper 6 closes inward. Through this transmission method, relying on the meshing of the teeth of the worm 9 and the worm gear 8, linear motion is precisely converted into circular motion.

[0036] When the "Open" button on handle 1 is pressed, the electric push rod 5 extends and pushes the worm gear 9 forward. The worm gear 9 drives the worm wheel 8 to rotate forward through the teeth 11, and the gripper 6 opens outward around the hinge seat 7. At this time, the user can adjust the direction of the handle and use the flexibility of the spring sleeve 3 to make the device go deeper into the pipe corner or depth, so that the opened gripper 6 can grab the target debris (such as hair clumps, food residue, etc.). After grabbing the debris, press the "Close" button on handle 1. The electric push rod 5 retracts and pulls the worm gear 9 backward. The worm wheel 8 rotates in the opposite direction and drives the gripper 6 to close, gripping the debris. After grabbing, the user removes the device from the pipe and presses the "Open" button again to release the gripper 6, and the debris can be removed. After the debris is grabbed and removed, the gripper 6, worm wheel 8, and worm gear 9 should be cleaned in time to avoid debris getting tangled in the parts and affecting subsequent work. The Hall sensor built into the electric actuator 5 provides real-time position information, ensuring precise and controllable opening and closing angles of the gripper 6. An independent battery compartment is provided in the handle section 1, housing a high-energy-density small lithium battery (such as an 18650 cell or lithium polymer battery). The battery capacity is set according to the power of the electric actuator 5 (generally 5-15W), meeting the needs of multiple operations per charge. The battery is electrically connected to the electric actuator 5 via a wire passing through the spring sleeve 3. During use, the battery directly provides DC power to the electric actuator 5 through the wire. Simultaneously, the battery is equipped with a charging protection circuit to prevent overcharging, over-discharging, and short circuits, extending its lifespan. When the battery is depleted, it can be recharged via a charger or power bank through the universal interfaces such as USB and Type-C on the surface of the handle section 1, making it suitable for scenarios without a fixed power source, such as homes and outdoors.

[0037] The waterproof sleeve 2 adopts a design that combines a rigid outer layer with a flexible seal. The outer metal tube provides structural support, and the inner wall is fitted with a rubber sealing ring. Through the compression sealing principle, sewage and silt are isolated, protecting the internal electric push rod 5 and transmission components. The spring sleeve 3 is made of multiple layers of tough materials and can bend with the direction of the pipe while maintaining sufficient pushing force, solving the problem that straight rod tools are difficult to penetrate into irregularly shaped pipes.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
