[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a detachable overflow-proof and odor-proof mobile toilet waste storage box, including an outer protective shell 1. The outer protective shell 1 is made of corrosion-resistant high-strength transparent plastic, and its surface is provided with anti-slip texture to improve the stability of handling. The waste storage box body 2 is embedded in the center of the upper inner side of the outer protective shell 1. The waste storage box body 2 is made of corrosion-resistant high-density polyethylene. The outer protective shell 1 plays a role in external protection of the waste storage box body 2, which can prevent the waste storage box body 2 from being physically damaged by external collisions, scratches and other physical damage. At the same time, it can isolate the influence of the external environment on the inside of the waste storage box to a certain extent, and avoid adverse effects on the state of the waste inside the waste storage box body 2 due to temperature changes.

[0028] A sewage discharge pipe 3 is connected and installed on the outer side wall of the sewage storage tank body 2 near the lower end. The sewage discharge pipe 3 is used to discharge the sewage stored in the sewage storage tank body 2. It can be connected to a sewage truck or other sewage discharge equipment to achieve centralized treatment of sewage. An inlet pipe 4 is connected and installed at the upper center of the sewage storage tank body 2. The interfaces of the inlet pipe 4 and the sewage discharge pipe 3 are both sealed with fluororubber rings to ensure their sealing performance. The fluororubber rings are replaced regularly. The inlet pipe 4 serves as the entry channel for sewage during the use of the mobile toilet, guiding the sewage in the mobile toilet into the sewage storage tank body 2. A connecting flange 5 is fixedly installed at the upper end of the inlet pipe 4. The connecting flange 5 facilitates a quick and secure connection between the inlet pipe 4 and the sewage discharge pipe of the mobile toilet. A tight sealing connection can be achieved through bolts and other connecting parts to prevent sewage leakage and odor emission, thus enabling the odor-proof function of the sewage storage tank body 2.

[0029] A special-shaped mounting base 6 is fixedly installed at the center of one end of the inner side of the outer protective shell 1. The special-shaped mounting base 6 provides the installation base for subsequent components such as the nut sleeve connector 7. Its special shape design is to better adapt to the installation and function of the nut sleeve connector 7. The nut sleeve connector 7 is embedded and fixedly installed at the center of one end of the special-shaped mounting base 6. The nut sleeve connector 7 cooperates with the rotating shaft 9 to drive the locking anchor clamp 8, so as to fix or remove the sludge storage tank body 2. The rotating shaft 9 is rotatably installed at the center of the inner side of the nut sleeve connector 7.

[0030] The rotating shaft 9 can rotate within the nut sleeve 7. Its rotational motion can drive the locking anchor clamp 8, which is threadedly engaged with it, to move axially. The outer wall of the rotating shaft 9 is threadedly fitted with the locking anchor clamp 8, which is made of flexible stainless steel. At the same time, a rubber pad is added to the inner side of the locking anchor clamp 8 to prevent surface scratches when the sludge tank body 2 is firmly fixed. The locking anchor clamp 8, through its threaded engagement with the rotating shaft 9, can lock or loosen the sludge tank body 2 when the rotating shaft 9 rotates, thereby realizing the detachable function of the sludge tank body 2.

[0031] An anti-overflow control valve 13 is installed at the flange connection of the middle section of the outer wall of the inlet connecting pipe 4. The anti-overflow control valve 13 is a float-type automatic valve. The anti-overflow control valve 13 is used to control the opening and closing of the inlet connecting pipe 4 and the flow rate. When the sludge in the sludge storage tank body 2 is close to full, the anti-overflow control valve 13 can be closed to prevent the sludge from overflowing into the portable toilet, thus playing the role of preventing overflow. A drain control valve 14 is installed at the flange connection of the middle section of the outer wall of the drain connecting pipe 3. The drain control valve 14 is a pneumatic butterfly valve. The valve body material is the same as that of the drain connecting pipe 3. The drain control valve 14 can control the opening and closing of the drain connecting pipe 3. When it is necessary to drain the sludge, the drain control valve 14 is opened to allow the sludge to be discharged smoothly. When it is not necessary to drain the sludge, the drain control valve 14 is closed to prevent the emission of odor and the leakage of sludge.

[0032] A movable bearing is rotatably mounted at the center of one side of both ends of the inner side of the outer protective shell 1. The movable bearing is a deep groove ball bearing filled with lithium-based grease. The movable bearing reduces the friction when the rotating shaft 9 rotates, making the rotation of the rotating shaft 9 smoother and ensuring the rotational accuracy of the rotating shaft 9. The rotating shaft 9 is rotatably mounted on the inner wall of the movable bearing, realizing the stable rotation of the rotating shaft 9 within the outer protective shell 1. A rotating handle 15 is fixedly mounted on one side of one end of the outer protective shell 1. The rotating handle 15 provides a force point for the operator, allowing the operator to rotate the rotating shaft 9 by rotating the handle 15, thereby realizing the operation of the locking anchor clamp 8 and completing the disassembly and installation process of the sludge storage tank body 2. The rotating handle 15 is fixedly mounted on one end of the rotating shaft 9, and the surface of the rotating handle 15 is covered with an anti-slip rubber layer. The connection between the rotating shaft 9 and the rotating handle 15 is a keyway fit. The rotating handle 15 is directly mounted on the rotating shaft 9, which can more directly transmit the rotational force of the operator, improving the convenience and efficiency of operation.

[0033] Example 2

[0034] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a circular groove is provided at the center of the upper end of the irregular mounting base 6 to facilitate the installation of the nut sleeve tube 7. The circular groove is adapted to the shape of the nut sleeve tube 7, and a rubber buffer pad is provided on the inner wall of the circular groove to reduce vibration and wear. This ensures that the nut sleeve tube 7 is accurately and stably positioned after installation, and avoids shaking or displacement during use. A hinge ring 10 is fixedly installed on the outer wall of the nut sleeve tube 7 near the upper end of the irregular mounting base 6. The hinge ring 10 provides a hinge mounting point for the locking anchor clamp 8, so that the locking anchor clamp 8 can move with the hinge ring 10 as the fulcrum, thereby realizing the locking and unlocking action of the sludge storage tank body 2. A movable locking anchor clamp 8 is fixedly installed on one side of the inner wall of the hinge ring 10. The locking anchor clamp 8 is installed on the hinge ring 10 by hinge, and can flexibly open and close.

[0035] The upper center of the nut sleeve 7 is provided with an arc-shaped groove to facilitate the movement of the locking anchor clamp 8. This arc-shaped groove provides space for the movement of the locking anchor clamp 8, ensuring that the locking anchor clamp 8 is not obstructed during opening and closing. At the same time, it provides a certain limiting effect on the locking anchor clamp 8 in the locked state. An anchor screw block 11 is fixedly installed on the outer wall of the rotating shaft 9. The anchor screw block 11 increases the meshing area and friction between the rotating shaft 9 and the locking anchor clamp 8, making the transmission between the two more stable and reliable, and effectively preventing slippage during use.

[0036] The outer wall of the anchoring screw block 11 is threadedly fitted with a locking anchor clamp 8. Through the threaded engagement, when the rotating shaft 9 rotates, the movement distance and position of the locking anchor clamp 8 can be precisely controlled. The inner side of the locking anchor clamp 8 is provided with equally spaced irregular threaded holes 12 to facilitate the engagement of the anchoring screw block 11. The anchoring screw block 11 has a trapezoidal thread structure to enhance its anti-loosening performance. The irregular threaded holes 12 are adapted to the shape of the anchoring screw block 11, further ensuring a tight fit between the two and improving the stability and reliability of locking and disassembly operations.

[0037] The remaining structure is the same as that in Example 1.

[0038] The workflow of this utility model is as follows:

[0039] First, when the portable toilet is in use, the operator rotates the handle 15 to rotate the rotating shaft 9. When the rotating shaft 9 rotates, the locking anchor clamp 8, which is threaded onto it, moves axially, so that the sludge tank body 2 conforms to the size of the locking anchor clamp 8 for installation inside the outer protective shell 1. Its inlet connection pipe 4 is fixedly connected to the sewage pipe of the portable toilet through the connecting flange 5, ensuring that sewage can smoothly enter the sludge tank. At the same time, the sewage connection pipe 3 controls the discharge of sewage through the sewage control valve 14 connected by the flange. The overflow control valve 13 is installed on the inlet connection pipe 4. Under normal circumstances, the overflow control valve 13 is in the open state, and sewage can smoothly enter the sludge tank body 2. As the sewage in the sludge tank body 2 gradually increases, when the sewage is close to full, the float ball of the overflow control valve 13 will actuate due to the rise in liquid level, closing the valve to prevent sewage from overflowing the portable toilet, thus playing an overflow prevention role.

[0040] Secondly, by rotating the handle 15, the rotating shaft 9 is driven to rotate. The anchoring screw block 11 on the rotating shaft 9 engages with the irregular screw hole 12 on the inner side of the locking anchor clamp 8, which drives the locking anchor clamp 8 to move axially. The locking anchor clamp 8 is gradually tightened or loosened by the support of the hinged snap ring 10, so as to adapt to the sludge storage tank body 2 of different diameters and shapes, ensuring that it is firmly fixed and without loosening.

[0041] Finally, when it is necessary to disassemble the sludge storage tank, rotate the handle 15 in the opposite direction to loosen the locking anchor clamp 8, and the sludge storage tank body 2 can be taken out from the outer protective shell 1. Throughout the process, the movable bearing and nut sleeve pipe 7 ensure the smooth rotation of the rotating shaft 9, while the flexible material and rubber pad of the locking anchor clamp 8 prevent scratches on the surface of the sludge storage tank. This allows the equipment to not only firmly fix the sludge storage tank body 2 of different diameters, but also to clamp and fix the sludge storage tank body 2 of different regular shapes, thus improving the applicability of the equipment. During the entire operation of the equipment, the various components work closely together to achieve the functions of detachable, overflow-proof, and odor-proof sludge storage tank.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
