Description

Technical Field

[0001] This invention relates to the field of garbage trucks, and in particular to a sewage leakage prevention device for the rear door of a garbage truck. Background Technology

[0002] In existing technologies, the problem of sewage leakage caused by poor sealing of the rear door of garbage trucks has attracted widespread attention. CN209834658U discloses a sewage anti-drip device for a compression garbage truck, which adopts a detachable collection box and a water pump pumping structure. The collection box can be quickly disassembled and assembled through a sliding rod sleeve mechanism, and the sewage is pumped back into the garbage truck using a water pump. Although this solution solves the problem of convenient installation of the collection box, it relies on electromechanical components for sewage transfer, which has high energy consumption and mechanical failure risk. CN201626665U adopts a combination structure of sealing strips and multi-stage guide plates, which guides leaked sewage to the chassis sewage tank through a sewage transition plate. However, the sealing strips are prone to aging and failure after long-term use, and the guide plate structure may obstruct material discharge during garbage dumping. CN214454008U is further improved with a dual-channel design, where a collection trough fixed to the rear door works in conjunction with the flow channel of the vehicle's wastewater tank. While this reduces wastewater splashing during transport, the rigid connection of the channels restricts the opening and closing of the rear door, affecting the smoothness of unloading operations. These existing technologies either rely on easily damaged seals or employ complex power systems that increase maintenance costs, making it difficult to simultaneously meet the dual requirements of leak-proof transport and convenient unloading. Summary of the Invention

[0003] This invention relates to a garbage truck leak-proof device and method. Existing garbage truck rear door sealing structures suffer from the problem of easily aging and damaging seals, leading to sewage leakage. Fixed sewage collection devices can obstruct operation during garbage dumping, while sewage transfer solutions relying on electromechanical components suffer from high energy consumption and complex maintenance. There is an urgent need for a solution that can effectively prevent sewage leakage during transportation without affecting garbage dumping operations, and can be installed on garbage trucks of various brands, specifications, and models without altering the original structure.

[0004] This invention provides a garbage truck anti-leakage device, including a garbage truck body and a garbage truck rear door. The device further includes an anti-sewage dripping channel, a hinge component, a rope hook, a rope hook lug, and a fastener. The anti-sewage dripping channel is movably connected to the garbage truck rear door. The rope hook is fixed to the garbage truck rear door. The rope hook lug and the hinge component are respectively fixed to the anti-sewage dripping channel. One end of the fastener is fixed to the garbage truck body, and the other end is fixed to the anti-sewage dripping channel for securing the channel.

[0005] Furthermore, the inner wall of the anti-drip trough is provided with an anti-corrosion layer. The inner wall is sprayed with an anti-corrosion coating such as epoxy resin asphalt paint or liquid rubber, and key sealing areas use ball-head soft foam rubber sealing strips or double-lip silicone sealing strips. This solution offers high cost-effectiveness and can meet the needs of most daily waste collection and transportation.

[0006] Furthermore, the bottom of the anti-sewage dripping tank is equipped with a drain valve, which can discharge the collected sewage.

[0007] Furthermore, the anti-sewage drip trough is movably connected to the rear door of the garbage truck via a freely rotatable hinge component, which is a hinge.

[0008] Furthermore, the fastener includes a buckle plate and a locking buckle. The buckle plate is installed on the side of the anti-sewage dripping trough, and the locking buckle is installed on the lower side of the rear of the garbage truck body. They are connected to each other and can be adjusted according to different distances and sizes to fix the anti-sewage dripping trough.

[0009] Furthermore, the locking buckle is a mechanical buckle that can be quickly engaged and disengaged.

[0010] Furthermore, the rope hook is fixed to the rear door of the garbage truck by welding or bolting.

[0011] Furthermore, the rope hook lugs and lugs are fixed to the anti-sewage dripping trough by welding or bolting.

[0012] A method for preventing garbage truck leaks includes the following steps: During transport, the anti-sewage drip trough is connected and fixed to the ear plate with locking buckles, so that it is in the position to receive sewage; In the unloading state, first open the drain valve to discharge the sewage in the anti-sewage drip trough, then loosen the locking buckle, rotate the anti-sewage drip trough through the hinge and hook the rope hook ear plate with the rope hook so that the anti-sewage drip trough is suspended on the rear door of the garbage truck.

[0013] When unloading, the anti-sewage drip chute opens along with the rear door of the garbage truck, without affecting the garbage dumping operation.

[0014] Furthermore, regularly inspect and maintain the anti-sewage drip tray and its connecting parts, and perform sealing repairs when corrosion and leakage occur in the anti-sewage drip tray.

[0015] This invention utilizes a drainage trough design to effectively collect leaked wastewater during transport, preventing road contamination. During unloading, a hinged rotation and rope hook suspension mechanism allow the trough to open synchronously with the garbage truck's rear door, ensuring unobstructed dumping. Specifically: 1) The trough's tilt angle design allows for natural wastewater collection; tests show it can collect over 98% of leaked liquid at a 5° tilt angle; 2) The linkage mechanism between the hinges and rope hooks automatically adjusts the trough's position during unloading, reducing operation time by 60% compared to traditional fixed structures; 3) The stainless steel construction combined with the drain valve design demonstrates a service life more than three times that of ordinary sealing strips, as shown in corrosion tests. This device requires no additional power source, achieving a balance between leak prevention and convenient unloading through a purely mechanical structure. Attached Figure Description

[0017] Figure 2 This is a magnified view of a section where the anti-sewage dripping trough is suspended.

[0018] Figure 3 This is a side view of the garbage truck in the unloading state. Detailed Implementation

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the garbage truck body 1 adopts a standard garbage truck body structure, and the garbage truck rear door 2 is installed on the garbage truck body 1 through a conventional connection method. The sewage drip-proof trough 5 is made of 304 stainless steel, and its length is equal to the width of the garbage truck rear door, with a depth of 20cm. The bottom of the trough is inclined at a 5° angle to facilitate sewage collection. The sewage drip-proof trough 5 is connected to the lower part of the garbage truck rear door 2 by two hinges 4. The hinges 4 are heavy-duty stainless steel hinges, and each hinge 4 is fixed to the sewage drip-proof trough 5 and the garbage truck rear door 2 by eight M8 stainless steel bolts respectively.

[0020] The rope hook 3 is made of 12mm diameter Q235 round steel and is fixed to the middle of the outer side of the garbage truck's rear door 2 with four M10 bolts. The rope hook lugs 8 and 6 are both made of 5mm thick Q235 steel plates and are welded to the two ends of the anti-sewage drip trough 5, respectively. The locking buckle 9 is a stainless steel quick-release buckle; its fixed end is welded to the garbage truck's rear door 2, and its movable end can be quickly connected to the holes on the lug 6. The drain valve 7 is a DN25 stainless steel ball valve, installed at the lowest point of the anti-sewage drip trough 5.

[0021] Figure 1In the transport state shown, the operator flips the anti-sewage drip trough 5 upwards to a horizontal position, allowing the movable end of the locking buckle 9 to insert into the hole of the ear plate 6 and lock it in place. At this time, the anti-sewage drip trough 5 forms a sealed joint with the rear door 2 of the garbage truck, and the sewage leaking during the garbage truck's transport flows into the anti-sewage drip trough 5 for temporary storage along the rear door. Actual measurements show that this structure can withstand more than 98% of leaked liquid.

[0022] Figure 2 , Figure 3 In the unloading state shown, the operator first opens the drain valve 7 to empty the sewage in the tank, and then unlocks the locking buckle 9. Holding the edge of the anti-sewage drip trough 5, the operator applies downward force, rotating it approximately 120° around the hinge 4 to a vertical position. At this point, the rope hook lug 8 is directly below the rope hook 3. After hooking the rope hook 3 onto the rope hook lug 8, the anti-sewage drip trough 5 is suspended and fixed in this position. When the garbage truck body 1 is lifted, the anti-sewage drip trough 5 opens outwards simultaneously with the rear door 2 of the garbage truck, completely clearing the garbage dumping path. The entire conversion process takes an average of 45 seconds, improving operational efficiency by 60% compared to the traditional fixed structure.

[0023] As an alternative implementation, the anti-drip trough 5 can be made of aluminum alloy, with its thickness increased to 3mm to improve structural strength. The hinge 4 can be replaced with a heavy-duty hinge with a limiting function, limiting the maximum opening angle to 135° to prevent excessive rotation. The connection between the rope hook 3 and the rope hook lug 8 can be changed to a pin-type quick-connect structure, with a through hole in the rope hook lug 8 and a spring pin at the end of the rope hook 3 for quick locking.

[0024] During maintenance, the hinge 4 should be checked weekly for smooth rotation; the locking buckle 9 and drain valve 7 should be lubricated monthly; and the sediment inside the anti-drip groove 5 should be cleaned quarterly. Corrosion tests show that this device has a service life of more than 5 years under normal operating conditions, which is 3 times the life of traditional sealing strips. All connecting bolts must be fitted with lock nuts, and their tightness must be checked monthly.
