Description

Technical Field

[0001] This invention relates to the field of glue bucket technology, and specifically to a sealant bucket with leak-proof function. Background Technology

[0002] Plastic drums have advantages such as being unbreakable, rust-free, lightweight, oil-resistant, and corrosion-resistant. They are widely used for the storage and transportation of various liquids. To prevent plastic drums from being broken due to repeated collisions during use, protective frames are often installed on the outside of the drums, which are called ton containers. The ton containers are protected by the protective frames during use, which can effectively protect the plastic drums from collision damage, and at the same time facilitate the orderly arrangement of multiple plastic drums for storage and transportation.

[0003] However, due to environmental factors (such as exposure to sunlight), plastic drums can still crack after a certain period of use or when exposed to sharp objects. When liquid is stored inside, a crack will cause leakage, leading to adverse effects. This is especially problematic when multiple drums are stacked, as timely repairs are difficult. Research indicates that existing leak-proof structures often employ a double-layer design. For example, Chinese utility model patent CN207312324U discloses a self-repairing leak-proof chemical raw material drum. This design uses a double-layer structure with an outer shell and an inner liner, with foam material placed between them. When either the outer shell or the inner liner cracks, the foam material seals the leak. The foam material alters the volume inside the inner liner and the surface area of ​​the outer shell. While this prevents leakage, it hinders the continued use of the drum. Another example is Chinese utility model patent CN116553027A. The patent discloses an emulsion transfer device with an alarm function. It employs a double-layer structure with an inner shell and an outer shell, and a microcapsule repair layer between the inner and outer shells. When the inner shell and / or the outer shell cracks or breaks, the pressure inside the interlayer decreases. Especially at the crack, the inner shell deforms under the pressure of the liquid and comes into contact with the outer shell. With shaking, friction forms between the two shells. The microcapsules, after being sheared and torn by the inner and outer shells, rupture and release their internal repair components, triggering a reactive polymerization reaction at room temperature. This bonding and repairs the shell cracks, providing a damage repair function. The deformation of the inner shell also changes its internal volume. Both of these structures involve placing a detection device within the interlayer and electrically connecting it to a corresponding control device, making the structure relatively complex and costly to replace.

[0004] Therefore, the present invention provides a sealant bucket with leak-proof function to solve the above problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a sealing glue bucket with anti-leakage function to solve the problem that the existing ton containers are affected by the environment (such as exposure to sunlight), and the glue bucket will still break after a certain period of use or when it encounters a sharp object. When liquid is stored inside, the breakage will cause liquid to leak out, which will cause adverse effects. In particular, when multiple ton containers are stacked, it is inconvenient to repair the breakage in time.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A leak-proof sealant bucket includes a bucket body, a protective frame, and a base positioned below the protective frame. The protective frame is equipped with a distance sensor for detecting the water level inside the bucket and a sealing mechanism for sealing the sides of the bucket body. The sealing mechanism includes several sealing components that slide inwards and outwards and are adapted to the sides of the bucket body. It also includes a control device for controlling the movement of the sealing components and electrically connected to the distance sensor via a controller. When a drop in the water level is detected, the control device controls the sealing components to seal the sides of the bucket body. A support plate is provided inside the bucket body, and a lifting rod is slidably connected to the support plate in a vertical direction. The lifting rod has a float plate at its bottom and a lifting plate at its top. A through hole is provided at the top of the bucket body corresponding to the lifting plate. The water level is detected by detecting the height of the lifting plate using the distance sensor.

[0008] Preferably, the barrel body, the protective frame, and the base are separately configured. The protective frame is provided with a positioning component for positioning the barrel body, and the distance sensor is hinged to the protective frame via a damping pivot.

[0009] Preferably, the positioning components are two positioning frames, one upper and one lower, that are fixedly installed inside the protective frame and adapted to the barrel body.

[0010] Preferably, a connector is provided between the four corners of the upper positioning frame and the protective frame, and the bottom of the base is provided with a slot that matches the connector.

[0011] Preferably, an isolation cylinder with a top opening is provided below the through hole at the top of the barrel, and the top of the lifting rod passes through the isolation cylinder and is slidably connected to the isolation cylinder in a sealed manner.

[0012] Preferably, a lead screw is provided between the lifting rod and the lifting plate, the lead screw is fixedly connected to the lifting plate and threadedly connected to the lifting rod.

[0013] The isolation cylinder and the support plate are flexibly provided with sealing connecting sleeves, and in the natural state, the sealing connecting sleeves are in a vertical state. The lifting rod is slidably connected to the isolation cylinder and the support plate through the sealing connecting sleeves. The floating plate is adapted to the inner wall of the barrel and is provided with an anti-collision protective layer on its periphery.

[0014] Preferably, the sealing element is plate-shaped with a sealing layer on the inner side. A first telescopic element is provided between the sealing element and the protective frame in the inward and outward direction, and a second telescopic element is provided between adjacent sealing elements in the head-to-tail direction. The control device is an electric telescopic element installed on the protective frame in the inward and outward direction. The control device is connected to one sealing element. When one sealing element is controlled to move, several sealing elements move synchronously.

[0015] Preferably, the sealing layer uses multiple water-swellable rubbers.

[0016] Preferably, the sealing component is detachably connected to the first telescopic component, the water-swellable rubber is detachably connected to the sealing component, the second telescopic component is rotatably connected to the sealing component, and a fixing component is provided.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. In this invention, a distance sensor monitors the water level inside the tank, and changes in the water level determine whether the tank is leaking. Specifically, when liquid leaks inside the tank, the liquid level drops, causing the float, lifting rod, and lifting plate to descend. The distance sensor detects the descent of the lifting plate, enabling timely detection of a tank rupture. The distance sensor transmits a signal to the control device via the controller, causing the control device to move the sealing mechanism. Several sealing components of the sealing mechanism seal and wrap the sides of the tank, temporarily sealing the ruptured portion and preventing further leakage. After sealing the tank, the position of the sealing mechanism can be observed to quickly determine the tank's condition, facilitating subsequent operations. Furthermore, when repairing the tank later, glass glue or tape can be used for repairs without affecting the overall volume and surface area, allowing the tank to continue to be used and saving costs.

[0019] 2. Because the present invention can automatically seal, it can temporarily seal without human intervention when stacking, arranging, storing or transporting items, making it convenient to use.

[0020] 3. The multiple sealing components in the sealing mechanism of this invention can provide auxiliary protection for the barrel body under normal circumstances, reduce the contact between sharp objects and the barrel body, and reduce the possibility of barrel body breakage.

[0030] The following will refer to the attached reference. Figures 1 to 8 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] Example 1

[0032] A leak-proof sealant container, as shown in the attached image. Figure 1 As shown, it includes a barrel body 3, a protective frame 2, and a base 1 located below the protective frame 2. The protective frame 2 can provide a certain degree of protection for the barrel body 3 itself. This part is existing technology and will not be described in detail here.

[0033] As attached Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8As shown, the protective frame 2 is equipped with a distance sensor 8 for detecting the water level inside the tank 3 and a sealing mechanism for sealing the sides of the tank 3. The sealing mechanism includes several sealing elements 5, which are slidably arranged in the inward and outward directions and adapted to the sides of the tank 3. In this embodiment, the tank 3 is a cuboid with four sides, and four sealing elements 5 are correspondingly arranged. It also includes a control device 4 for controlling the movement of several sealing elements 5 and electrically connected to the distance sensor 8 through a controller (not shown in the figure). When the water level inside the tank 3 is detected to drop, the four sealing elements 5 are controlled to seal the sides of the tank 3. A support plate 13 is provided near the top inside the tank body 3. The support plate 13 is sealed to the inner wall of the tank body 3, that is, the support plate 13 divides the inside of the tank body 3 into two spaces. A lifting rod 16 is sealed and slidably connected to the support plate 13 in the vertical direction. A float 15 is provided at the bottom of the lifting rod 16. The float 15 is made of a material with high buoyancy to ensure that the float 15 always floats on the liquid surface. A lifting plate 18 is provided at the top of the lifting rod 16. A through hole is provided at the top of the tank body 3 corresponding to the lifting plate 18. The position of the distance sensor 8 corresponds to the through hole. The water level is detected by detecting the height of the lifting plate 18 through the distance sensor 8.

[0034] Working principle: When liquid is stored in the tank 3, the float 15 is level with the liquid surface due to buoyancy. The float 15, lifting rod 16 and lifting plate 18 are kept at a certain height. The height of the lifting plate 18 is monitored by the distance sensor 8, which in turn monitors the liquid level in the tank 3. When the liquid level changes, the heights of the float 15, lifting rod 16 and lifting plate 18 change together. The distance sensor 8 can detect this in time and transmit a signal to the control device 4 through the controller, causing the control device 4 to drive the sealing mechanism to move. Several sealing parts 5 of the sealing mechanism seal and wrap the sides of the tank 3.

[0035] In this embodiment, when in use, first control the sealing part 5 of the sealing mechanism away from the barrel 3 so that the side of the barrel 3 is exposed. Then, continuously add liquid into the barrel 3 and observe. If leakage is found in the barrel 3 itself when adding liquid, stop adding liquid, drain the liquid and replace it. If there is no leakage in the barrel 3, after adding liquid, the distance sensor 8 can be activated by the controller to monitor the height of the lifting plate 18.

[0036] This embodiment can promptly seal the broken parts of the barrel 3 to prevent further leakage. After sealing the barrel 3, the status of the barrel 3 can be quickly determined by observing the position of the sealing mechanism. If the barrel 3 is not broken, the device can be stored normally after normal drainage for future use. If the barrel 3 is broken, the device can be stored separately after normal drainage, allowing for quick identification of broken barrels 3 for repair and other subsequent processing. Because this embodiment can automatically seal, temporary sealing can be performed without manual operation during stacking, storage, or transportation, making it convenient to use. The multiple sealing components 5 in the sealing mechanism of this embodiment can provide auxiliary protection for the barrel 3 under normal conditions. Sharp objects will contact the sealing components 5 first, reducing the contact between sharp objects and the barrel 3 and thus reducing the possibility of the barrel 3 breaking.

[0037] Additionally, it should be noted that the liquid surface may slosh during transportation, which could lead to inaccurate monitoring. Therefore, this embodiment is suitable for use when the liquid is stored statically.

[0038] In addition, it should be noted that the sealing component 5 in this embodiment should be made of a material with a certain deformation capacity and a certain acid and alkali resistance. In actual production and use, this ensures that when sealing the barrel 3, it can fit tightly against the not completely smooth side of the barrel 3 and can be used with a variety of liquids.

[0039] Additionally, it should be noted that in this embodiment, when leakage occurs during liquid addition, the leakage begins when the liquid is added to the crack, allowing for timely detection and cessation of liquid addition, thus preventing widespread leakage.

[0040] Example 2

[0041] As attached Figure 1 , Figure 2 As shown, the difference from Embodiment 1 is that in this embodiment, the barrel 3 is separately set from the protective frame 2 and the base 1. That is, the barrel 3 can be placed on the base 1 and can be taken out separately. The protective frame 2 is provided with a positioning component 10 for positioning the barrel 3. Specifically, the positioning component 10 is a set of two positioning frames, upper and lower, that are fixedly set inside the protective frame 2 and adapted to the barrel 3. The upper positioning frame is provided with a connecting piece 6 between the four corners and the protective frame 2, and the lower positioning frame is directly fixed to the base 1. The distance sensor 8 is hinged to the protective frame 2 through a damping pivot and a hinge rod 9.

[0042] Working principle: The barrel 3 placed on the base 1 is positioned by the upper and lower positioning frames. After positioning, the position of the distance sensor 8 can be adjusted by the rotation of the hinge rod 9 and the positioning of the damping shaft, which makes it easy to pick up and put down the barrel 3.

[0043] In this embodiment, during actual use, the barrel 3 is initially separated from the base 1 and the protective frame 2. Liquid is continuously added to the barrel 3 in this state, and the process is observed. If leakage is detected in the barrel 3 during liquid addition, the addition is stopped, the liquid is drained, and the problematic barrel 3 is replaced. If there is no leakage in the barrel 3, after adding liquid, the barrel 3 is placed on the base 1 using the positioning frame. Before and after placement, the position of the distance sensor 8 is adjusted accordingly using the hinge rod 9. Finally, the distance sensor 8 is activated by the controller to monitor the height of the lifting plate 18. Afterwards, the liquid in the barrel 3 is drained, and then the barrel 3 is removed for further processing.

[0044] In this embodiment, if a problem is found in the container 3 itself when adding liquid, the problematic container 3 can be collected and processed separately. The container 3 itself is lightweight and easy to handle.

[0045] In this embodiment, during liquid addition, the barrel 3 is separated from the protective frame 2 and the base 1. If the barrel 3 is cracked, the leaked liquid will not contaminate the protective frame 2 and the base 1. Furthermore, since the barrel 3 is separated from the protective frame 2 and the base 1, the side of the barrel 3 is not obstructed, making it easy to observe. In this embodiment, after leakage occurs and the barrel 3 is sealed, the liquid in the barrel 3 is drained first, and then the barrel 3 is removed. The barrel 3 can be repaired or replaced, and the protective frame 2 and the base 1 can be reused, saving costs.

[0046] Additionally, it should be noted that, since the barrel 3 needs to be separated from the protective frame 2 and the base 1 in this embodiment, the liquid filling and draining of the barrel 3 can share a single liquid passage pipe 14. The liquid passage pipe 14 can be set on the top of the barrel 3 and equipped with a sealing cap 12 to prevent contact with the protective frame 2 when the barrel 3 is taken out or placed. The bottom of the liquid passage pipe passes through the support plate 13. When adding or draining liquid, another pipe can be inserted into the inside of the barrel 3 for adding or draining liquid.

[0047] In addition, it should be noted that a certain fixing device, such as a pin structure, can also be set between the hinge rod 9 and the barrel 3 in this embodiment. After the hinge rod 9 and the barrel 3 are fixed, the hinge rod 9 limits the barrel 3 in the vertical direction, so that the distance sensor 8 and the barrel 3 can maintain a relatively fixed state, ensuring accurate monitoring results.

[0048] Additionally, it should be noted that in this embodiment, the bottom of the base 1 is also provided with a slot that matches the connector 6, as shown in the attached diagram. Figure 8 This makes it easy to stack them one on top of the other.

[0049] Example 3

[0050] As attached Figure 1 , Figure 5As shown, the difference between this embodiment and embodiment two is that in this embodiment, an isolation cylinder 19 with a top opening is provided below the through hole at the top of the barrel 3. The top of the lifting rod 16 passes through the isolation cylinder 19 and is slidably connected to the isolation cylinder 19 in a sealed manner, which isolates the space above the support plate 13 inside the barrel 3 from the outside world, which can play a role in dust prevention and leave a certain space for the distance sensor 8 to rotate into the isolation cylinder 19.

[0051] As attached Figure 1 , Figure 5 , Figure 6 As shown, in this embodiment, a lead screw 20 is provided between the lifting rod 16 and the lifting plate 18. The lead screw 20 is fixedly connected to the lifting plate 18 and threadedly connected to the lifting rod 16. By rotating the lifting plate 18, the lead screw 20 is driven to rotate, which can adjust the distance between the lifting plate 18 and the lifting rod 16. When the liquid stored in the tank 3 is relatively large, the float 15 is higher, and the lead screw 20 can be adjusted to extend a shorter distance, so that the lifting plate 18 is closer to the lifting rod 16. Thus, under normal conditions, the lifting plate 18 can be located inside the isolation cylinder 19. When the liquid stored in the tank 3 is relatively small, the float 15 is lower, and the lead screw 20 can be adjusted to extend a longer distance, so that the lifting plate 18 is relatively far away from the lifting rod 16. Thus, under normal conditions, the lifting plate 18 can be located inside the isolation cylinder 19. This not only provides some protection for the distance sensor 8, but also does not affect the stacking.

[0052] Additionally, it should be noted that in this embodiment, when the lifting plate 18 is monitored by the distance sensor 8, there will be a gap at the top of the isolation cylinder 19. Debris may fall into the isolation cylinder 19, and the distance sensor 8 may detect a decrease in distance. It is only necessary to set the controller so that when the distance is detected to be longer, i.e. when the liquid level is lower, the control device 4 is controlled to move the sealing mechanism. When the distance is detected to be longer, the control device 4 is not controlled to move. Alternatively, a certain sealing mechanism can be set at the isolation cylinder 19 to prevent debris from falling into the isolation cylinder 19.

[0053] Example 4

[0054] As attached Figure 1 , Figure 5 , Figure 6As shown, the difference between this embodiment and Embodiment 3 is that, in this embodiment, a flexible sealing connecting sleeve 17 is provided on the isolation cylinder 19 and the support plate 13. Specifically, the sealing sleeve can be provided with an elastic rubber connecting sleeve around its periphery. In its natural state, the sealing connecting sleeve 17 is vertical, and the lifting rod 16 is slidably connected to the isolation cylinder 19 and the support plate 13 through the sealing connecting sleeve 17, allowing for normal testing. The float 15 is adapted to the inner wall of the barrel 3, that is, the periphery of the float 15 is slightly smaller than the inner wall of the barrel 3. In its natural state, the periphery of the float 15 does not contact the inner wall of the barrel 3. Normal testing is performed, and the float 15 is equipped with an anti-collision protective layer around its perimeter. The anti-collision protective layer can be made of several rubber protrusions. When subjected to a certain external force, the lifting rod 16 can tilt at a certain angle through the elastic rubber sleeve. When tilted, the perimeter of the float 15 contacts the inner wall of the tank 3 through the anti-collision layer. In the tilted state, the inner wall of the tank 3 can be cleaned and descaled. In actual use, the adjusting screw 20 extends a long distance, and the operation can be carried out using the principle of force-saving lever. Alternatively, a detachable operating handle can be set at the lifting plate 18. When cleaning the tank 3, the operating handle can be installed for operation.

[0055] Example 5

[0056] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the difference between this embodiment and embodiment four is that in this embodiment, the sealing member 5 is plate-shaped with a sealing layer on the inner side. A first telescopic member 7 is provided between the sealing member 5 and the protective frame 2 in the inward and outward direction to realize the inward and outward movement of the sealing member 5. A second telescopic member 11 is provided between adjacent sealing members 5 in the head-to-tail direction. In this embodiment, three sets of first telescopic members 7 are provided between the four sealing members 5. The control device 4 is an electric telescopic member set on the protective frame 2 in the inward and outward direction. The control device 4 is connected to one sealing member 5. When one sealing member 5 is controlled to move, several sealing members 5 move synchronously.

[0057] Working principle: The angle between the second telescopic component 11 and the two side sealing components 5 remains unchanged. When one sealing component 5 moves, it drives the other sealing components 5 to move synchronously. It only needs to be controlled by one control device 4, and the structure is simple and convenient.

[0058] As attached Figure 7 As shown, in this embodiment, the sealing layer uses multiple water-swellable rubbers. The water-swellable rubbers can come into contact with the liquid and expand to a certain extent when leaking, thus sealing the leak tightly. Specifically, after sealing and draining the liquid, the leak location of the barrel 3 can be quickly determined according to the expansion position of the water-swellable rubbers, which facilitates the repair of the barrel 3.

[0059] As attached Figure 3 , Figure 4 , Figure 7As shown, in this embodiment, the sealing component 5 is detachably connected to the first telescopic component 7. The water-swellable rubber is detachably connected to the sealing component 5. The second telescopic component 11 is rotatably connected to the sealing component 5 and is provided with a fixing component. The specific structure of the fixing component can be a screw. In actual use, when the sealing component 5 is connected to the first telescopic component 7, the angle of the second telescopic component 11 is fixed by the fixing component to ensure that each sealing component 5 moves synchronously. When the sealing component 5 is separated from the first telescopic component 7, the fixing component can be removed, so that the sealing component 5 can rotate relative to each other and expose the sealing layer. When the stored liquid is a liquid with a certain acidity or alkalinity and an accident occurs, the sealing layer expands and seals, and will also be damaged to a certain extent. Afterwards, the sealing component 5 can be removed and unfolded to find the corresponding position and replace that part to ensure the sealing effect next time.

[0060] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
