[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] During actual use, it was found that the existing waterproof structure has some significant defects. First, the baffle 5 needs to be pasted on the tank foundation. This process is not only time-consuming and labor-intensive, but also requires extremely high construction precision. Any deviation in the pasting position may lead to inconsistent quality of subsequent asphalt paving, affecting the overall waterproof effect. In addition, the pasted baffle 5 is easy to fall off during long-term use, which will weaken the integrity of the waterproof layer and increase maintenance costs and workload. In order to solve the above problems, the following structure is specially invented.

[0024] like Figures 1-9 The waterproof structure of a storage tank and foundation shown in the figure includes a storage tank body 1 and a foundation platform 2. Before the foundation platform 2 is cast, an L-shaped round steel 3 is embedded. The top of the L-shaped round steel 3 is fixedly connected to a circular steel plate 4, and the top of the circular steel plate 4 is flush with the top of the foundation platform 2. The bottom of the storage tank body 1 is fixedly connected to the top of the foundation platform 2, and the edge plate of the bottom of the storage tank body 1 is fixed to the top of the circular steel plate 4 by welding. The outer side of the base platform 2 is provided with a plurality of baffles 5, and a pair of fixing blocks 6 is arranged at the top end of the circular steel plate 4 relative to the position beside the baffle 5. A side hole 7 is formed in the side wall of the fixing block 6, and a plug frame 8 is fixedly connected to the side wall of the fixing block 6. A plurality of plug holes 9 are formed in the side wall of the baffle 5 relative to the position beside the plug frame 8, and the plug frame 8 is inserted into the plug hole 9. A plug rod 10 is inserted into the plug frame 8, and a limiting mechanism is arranged on the fixing block 6 for limiting the position of the plug rod 10. When the base platform 2 is poured, the L-shaped circular steel 3 and the circular steel plate 4 need to be pre-buried in the concrete first, and then after the base platform 2 is solidified, the storage tank body 1 can be constructed, the storage tank body 1 is fixed on the base platform 2, then the edge plate at the bottom of the storage tank body 1 is welded on the circular steel plate 4, and then the baffle 5 can be covered on the outer side of the base platform 2 in sequence, and the position is limited by the limiting mechanism on the fixing block 6. After the position of the baffle 5 is locked and fixed, asphalt can be poured between the baffle 5 and the outer wall of the storage tank body 1, and finally a waterproof film is covered on the asphalt and the baffle 5 to complete the waterproof treatment.

[0025] The side wall of the plug rod 10 is fixedly connected with an extrusion plate 11, and the side wall of the plug frame 8 is provided with an extrusion groove 12 relative to the position beside the extrusion plate 11. After the plug rod 10 is locked, the extrusion plate 11 is tightly attached to the outer wall of the baffle 5. The limiting mechanism comprises a limiting block 13, a lower groove 14 is formed at the bottom end of the side hole 7, a sliding block 15 is slidably connected to the inner side of the lower groove 14, the limiting block 13 is fixedly connected to the top end of the sliding block 15, and the limiting block 13 is arranged obliquely relative to the side of the plug frame 8. An upper spring 16 is fixedly connected between the bottom end of the lower groove 14 and the bottom end of the sliding block 15, and a plurality of limiting grooves 17 are equidistantly formed at the bottom end of the plug rod 10, and the limiting grooves 17 are arranged obliquely relative to the side of the plug frame 8. A lower frame 18 is fixedly connected to the inner side of the baffle 5 relative to the position of the plug frame 8, and the lower frame 18 is in communication with the plug frame 8. A sliding frame 19 is slidably connected to the inner side of the lower frame 18, and a middle plate 20 is fixedly connected to the inner side of the lower frame 18 relative to the inner side of the sliding frame 19. The top end of the sliding frame 19 is arranged as a smooth arc surface, the bottom end of the side wall of the plug rod 10 is arranged obliquely, and the inner side of the baffle 5 is fixedly connected with a limiting ring 22 relative to the position above the base platform 2 (it should be noted that the side wall of the baffle 5 and the bottom end of the limiting ring 22 are both pasted with sealing pads, and the sealing performance between the baffle 5 and the base platform 2 after locking is ensured by the arrangement of the sealing pads, and the waterproof effect of the device is further improved). A lower spring 21 is fixedly connected between the top end of the middle plate 20 and the inner top end of the sliding frame 19, and the sliding frame 19 is pushed to the retracted state when the plug rod 10 is not inserted, which avoids affecting the normal insertion of the baffle 5 on the plug frame 8. The sliding frame 19 is arranged above the limiting ring 22, the baffle 5 is made of elastic iron material, and the baffle 5 can be deformed arbitrarily according to the shape of the base platform 2. In the process of installing the baffle 5, first pass one of the insertion holes 9 of the baffle 5 through the insertion frame 8, then bend the baffle 5 to deform, so that the insertion hole 9 on the other side of the baffle 5 passes through the other insertion frame 8, and then the insertion rod 10 is inserted into the insertion frame 8. In this process, the insertion rod 10 first passes above the sliding frame 19, and then the inclined surface at the side end of the insertion rod 10 extrudes the arc surface at the top end of the sliding frame 19, so that the sliding frame 19 slides downward in the lower frame 18 and compresses the upper spring 21. Then the arc surface at the top end of the sliding frame 19 moves away from the inclined surface of the insertion rod 10, and the bottom end of the insertion rod 10 moves to the sliding frame 19, so that the bottom end of the sliding frame 19 is extruded on the limiting ring 22, and then the limiting ring 22 is tightly extruded on the base platform 2. Then the insertion rod 10 continues to be inserted, and the end of the insertion rod 10 moves to the side of the limiting block 13, and then the inclined surface at the side end of the insertion rod 10 extrudes the inclined surface of the limiting block 13, so that the limiting block 13 slides downward, and at the same time drives the sliding block 15 to slide downward in the lower groove 14 and compresses the upper spring 16. Then when part of the limiting groove 17 moves above the limiting block 13, the extrusion on the limiting block 13 is released, and then the sliding block 15 and the limiting block 13 are pushed upward under the elastic force of the upper spring 16, and then the limiting block 13 is inserted into the corresponding limiting groove 17. With the continuous insertion of the insertion rod 10, the inclined surface of the limiting groove 17 extrudes the inclined surface of the limiting block 13, so that the limiting block 13 slides downward, and at the same time drives the sliding block 15 to move downward, until the other limiting groove 17 moves above the limiting block 13. Under the elastic force of the upper spring 16, the insertion is pushed, and so on, until the extrusion plate 11 passes through the extrusion groove 12, and the baffle 5 is tightly extruded on the side wall of the lower frame 18, so as to realize the rapid fixation of the baffle 5.

[0026] In order to further ensure the plugging effect of the middle part of the baffle 5 after being locked, the top middle part of the limiting ring 22 is provided with a positioning groove 25, and the outer wall of the circular steel plate 4 is fixedly connected with a supporting rod 23 relative to the middle part of the baffle 5. The top end of the supporting rod 23 is fixedly connected with a positioning rod 24. After the baffle 5 is covered outside the base platform 2 and one of the insertion holes 9 passes through the insertion frame 8, the positioning groove 25 on the limiting ring 22 needs to pass through the positioning rod 24 to limit the middle part of the baffle 5, so as to avoid the deformation of the baffle 5 and the limiting ring 22 and the phenomenon of hollowing in the middle.

[0027] In summary, through the design of the above structure, the baffle 5 can be quickly locked and fixed outside the base platform 2, providing shielding and sealing effect for subsequent asphalt pouring. At the same time of locking, the limiting ring 22 inside the baffle 5 can be tightly extruded on the base platform 2, further improving the sealing effect of the baffle 5, and after subsequent asphalt pouring, the limiting ring 22 can be pressed, improving the stability of the baffle 5.

[0028] On the basis of the above embodiment, it is found that during the pouring process of the base platform 2, size deviation problems are inevitable, and then due to the fixed locking distance between the fixed block 6 and the baffle 5, if deviation occurs, it will affect the normal locking and fixing of the position of the baffle 5. In order to solve the above problems, the above structure is further improved.

[0029] A plurality of rectangular grooves 35 are equidistantly arranged at the top end of the circular steel plate 4 relative to the position below the fixed block 6, the bottom end of the fixed block 6 is fixedly connected with a rectangular block 26 matched with the rectangular groove 35, the bottom end of the side hole 7 is provided with a bottom groove 27, and the bottom groove 27 penetrates the bottom end of the rectangular block 26, the outer wall of the rectangular block 26 is provided with a limiting block 28 connected with the outer wall through horizontal sliding, the top end of the side close to the limiting block 28 is inclined, the inside of the bottom groove 27 is provided with a cross 29 connected with the inside of the bottom groove 27 through longitudinal sliding, and the bottom end of the cross 29 is inclined, the top end of the cross 29 is inclined, and the inside of the rectangular groove 35 is provided with a limiting groove 30 matched with the limiting block 28 at both ends; The inclined surface at both sides of the bottom end of the cross 29 is matched with the inclined surface of the limiting block 28, the side plate 31 is fixedly connected with the both sides of the bottom groove 27, the reset spring 32 is fixedly connected between the top end of the side plate 31 and the bottom end of the cross 29, the top end of the limiting block 28 is fixedly connected with the top plate 33, and the limiting spring 34 is fixedly connected between the side wall of the top plate 33 and the side wall of the bottom groove 27; When the insertion hole 9 on the baffle 5 penetrates the insertion frame 8, if the inside of the extrusion groove 12 is not aligned with the outer wall of the baffle 5, it means that the extrusion plate 11 cannot tightly extrude the baffle 5 on the side wall of the lower frame 18, and the phenomenon of upward inclination will occur. At this time, the rectangular block 26 on the fixed block 6 needs to be pulled out from the rectangular groove 35, the rectangular block 26 on the fixed block 6 is inserted into the corresponding rectangular groove 35 according to the position of the extrusion groove 12, and then the insertion rod 10 is inserted to repeat the above operation to lock the position of the baffle 5. When the insertion rod 10 is inserted into the side hole 7, the inclined surface at the side end of the insertion rod 10 will extrude the inclined surface at the top end of the cross 29, and then since the cross 29 can only slide up and down, under the extrusion of the inclined surface of the insertion rod 10, the cross 29 will be pushed to move downward, and the reset spring 32 will be compressed. At this time, the inclined surface at the bottom end of the cross 29 will extrude the inclined surface at one side of the limiting block 28 close to the both sides, and then since the limiting block 28 can only slide horizontally, under the extrusion of the inclined surface of the cross 29, the limiting block 28 will be pushed to slide to the both sides to extend the rectangular block 26, and then the limiting block 28 will be inserted into the corresponding limiting groove 30, and the side plate 31 will be moved and the limiting spring 34 will be compressed, so as to lock the position of the rectangular block 26 in the rectangular groove 35, and then the position of the fixed block 6 is limited (it should be noted that since the fixed block 6 is inserted into the rectangular groove 35 through the rectangular block 26, when the insertion rod 10 is inserted and locked, it will not be affected. This step is only to limit the upward pulling of the fixed block 6); It should be noted that the deviation appearing at this place is within the normal deviation value of the construction of the base platform 2, and will not affect the size of all the baffle plates 5 combined on the outside of the base platform 2, and it should be noted that when installing the baffle plate 5 at the position where the deviation occurs, a plate longer than the length of the other baffle plates 5 can be used, and then by cutting, the gap at the position where the deviation occurs can be filled, so that there will be no gap between the baffle plates 5, which will affect the sealing effect of the asphalt, and the adjustment of the fixing block 6 is only to lock the baffle plate 5 on the outside of the base platform 2, to ensure the shielding effect during subsequent asphalt pouring.

[0030] In summary, through the design of the above structure, the position of the fixing block 6 can be flexibly adjusted according to the distance between the base platform 2 and the circular steel plate 4, and the position of the fixing block 6 can be locked at the same time as the baffle plate 5 is locked, which improves the flexibility of the device and meets the use of different sites.

[0031] The above shows and describes the basic principles, main features and advantages of the present application.

[0032] Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
