DETAILED DESCRIPTION

[0032] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be practiced in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed below.

[0034] In practical 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 prone to falling off during long-term use, which will weaken the integrity of the waterproof layer and increase maintenance costs and workload. To solve the above problems, the following structure was invented.

[0035] like Figures 1-9 The waterproof structure of a storage tank and foundation shown includes a storage tank body 1 and a foundation platform 2. Before the foundation platform 2 is poured, an L-shaped round steel bar 3 is pre-embedded. A circular steel plate 4 is fixedly connected to the top of the L-shaped round steel bar 3, 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.

[0036] Several baffles 5 are provided on the outer side of the base platform 2. A pair of fixing blocks 6 are provided at the top of the circular steel plate 4 relative to the position next to the baffles 5. Side holes 7 are opened on the side wall of the fixing blocks 6. Insertion frames 8 are fixedly connected to the side wall of the fixing blocks 6. Insertion holes 9 are opened on the side wall of several baffles 5 relative to the position next to the insertion frames 8. The insertion frames 8 are inserted into the inside of the insertion holes 9. Insertion rods 10 are inserted into the insertion frames 8. The fixing blocks 6 are provided with a limiting mechanism for limiting the position of the insertion rods 10.

[0037] When pouring the foundation platform 2, the L-shaped round steel 3 and the circular steel plate 4 need to be pre-embedded in the concrete. After the foundation platform 2 solidifies, the storage tank body 1 can be constructed. The storage tank body 1 is fixed on the foundation platform 2. Then, the edge plate at the bottom of the storage tank body 1 is welded to the circular steel plate 4. Then, the baffle 5 can be placed on the outside of the foundation platform 2 in sequence, and the position is limited by the limiting mechanism on the fixing block 6.

[0038] After the baffle 5 is locked and fixed, asphalt can be poured between the baffle 5 and the outer wall of the storage tank 1. Finally, a waterproof membrane is covered on the asphalt and the baffle 5 to complete the waterproofing treatment.

[0039] A pressing plate 11 is fixedly connected to the side wall of the insertion rod 10. A pressing groove 12 is opened on the side wall of the insertion frame 8 relative to the pressing plate 11. After the insertion rod 10 is locked, the pressing plate 11 is tightly attached to the outer wall of the baffle 5.

[0040] The limiting mechanism comprises a limiting block 13, the bottom end of the side hole 7 is provided with a lower groove 14, 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 obliquely arranged close to one side of the insertion 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; a plurality of limiting grooves 17 are equidistantly formed in the bottom end of the insertion rod 10, and the limiting grooves 17 are obliquely arranged close to one side of the insertion frame 8;

[0041] A lower frame 18 is fixedly connected to the inner side of the position of the bottom end of the insertion frame 8 relative to the baffle 5, and the lower frame 18 is in communication with the inside of the insertion frame 8; a sliding frame 19 is slidably connected to the inner side of the lower frame 18; a middle plate 20 is fixedly connected to the inner side of the position of the sliding frame 19 relative to the inner side of the lower frame 18; the top end of the sliding frame 19 is arranged as a smooth arc surface; the bottom end of the side wall of the insertion rod 10 is obliquely arranged; a limiting ring 22 is fixedly connected to the position above the baffle 5 relative to 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, thereby further improving the waterproof effect of the device);

[0042] 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 arrangement of the lower spring 21 facilitates the sliding frame 19 to be in a retracted state when the insertion rod 10 is not inserted, thereby avoiding affecting the normal insertion of the baffle 5 on the insertion 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 according to the shape of the base platform 2;

[0043] During the installation of the baffle 5, first, one of the insertion holes 9 of the baffle 5 passes through the insertion frame 8, then the baffle 5 is bent to deform, so that the other insertion hole 9 of the baffle 5 passes through the other insertion frame 8, and then the insertion rod 10 can be inserted into the insertion frame 8; in this process, the insertion of the insertion rod 10 will first pass above the sliding frame 19, and then the inclined surface of the side end of the insertion rod 10 will extrude the arc surface at the top end of the sliding frame 19, so that the sliding frame 19 will slide downward in the lower frame 18 and compress the lower spring 21; then the arc surface at the top end of the sliding frame 19 will move away from the inclined surface of the insertion rod 10, the bottom end of the insertion rod 10 will move to the sliding frame 19, thereby driving the bottom end of the sliding frame 19 to extrude the limiting ring 22, and then the limiting ring 22 will be tightly extruded on the base platform 2;

[0044] Then the plug 10 continues to insert, the end of the plug 10 will move to the limit block 13 side, and then through the inclined surface of the side end of the plug 10 extruding the inclined surface of the limit block 13, the limit block 13 slides down, at the same time, the sliding block 15 slides down in the lower groove 14, and the upper spring 16 is compressed, then when the limit groove 17 moves above the limit block 13, the extrusion of the limit block 13 is released, and then the sliding block 15 and the limit block 13 are pushed up by the elastic force of the upper spring 16, and then the limit block 13 is inserted into the corresponding limit groove 17, and with the continuous insertion of the plug 10, the inclined surface of the limit groove 17 extrudes the inclined surface of the limit block 13, and the limit block 13 slides down, at the same time, the sliding block 15 moves down until another limit groove 17 moves above the limit block 13, and the insertion is pushed by the elastic force of the upper spring 16, 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 quick fixing of the baffle 5.

[0045] In order to further ensure the plugging effect of the middle part of the baffle 5 after locking, the top middle part of the limit ring 22 is provided with a positioning groove 25, and the outer wall of the circular ring steel plate 4 is fixedly connected with a support rod 23 at the middle part of the baffle 5.

[0046] After the baffle 5 covers the outer side of the base platform 2 and one of the insertion holes 9 passes through the insertion frame 8, the positioning groove 25 on the limit ring 22 needs to pass through the positioning rod 24 to limit the middle part of the baffle 5, so that the baffle 5 and the limit ring 22 can be prevented from deforming and appearing hollow in the middle.

[0047] In summary, through the design of the above structure, the baffle 5 can be quickly locked and fixed on the outer side of the base platform 2, providing shielding and sealing effect for subsequent asphalt pouring, and at the same time of locking, the limit ring 22 on the inner side of 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 limit ring 22 can be pressed, improving the stability of the baffle 5.

[0048] On the basis of the above embodiment, it is found that during the pouring process of the base platform 2, size deviation problem is inevitable, and then due to the fixed locking distance between the fixed block 6 and the baffle 5, if deviation occurs, the normal locking and fixing of the baffle 5 position will be affected, in order to solve the above problem, the above structure is further improved.

[0049] A plurality of rectangular grooves 35 are equidistantly arranged on the top end of the circular steel plate 4 relative to the position below the fixing block 6, the bottom end of the fixing 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 penetrating through the bottom end of the rectangular block 26, the outer wall of the rectangular block 26 is penetrated by a limiting block 28 connected in a transverse sliding mode, the top end of the side close to the limiting block 28 is arranged in an inclined mode, the inside of the bottom groove 27 is longitudinally connected with a cross 29, the bottom end of the cross 29 is arranged in an inclined mode, the top end of the cross 29 is arranged in an inclined mode, and the inside of the rectangular groove 35 is provided with a limiting groove 30 matched with the limiting block 28 at both ends;

[0050] The inclined surface of the bottom end of the cross 29 is matched with the inclined surface of the limiting block 28, the both sides of the bottom groove 27 are fixedly connected with a side plate 31, the top end of the side plate 31 and the bottom end of the cross 29 are fixedly connected with a return spring 32, the top end of the limiting block 28 is fixedly connected with a top plate 33, and the side wall of the top plate 33 and the side wall of the bottom groove 27 are fixedly connected with a limiting spring 34;

[0051] When the insertion hole 9 on the baffle 5 penetrates through the insertion frame 8, the inside of the extrusion groove 12 is not aligned with the outer wall of the baffle 5, which 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 fixing block 6 is pulled out from the rectangular groove 35, the rectangular block 26 on the fixing 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 of the side end of the insertion rod 10 will extrude the inclined surface of the top end of the cross 29, and thus the cross 29 can only move up and down, so under the extrusion of the inclined surface of the insertion rod 10, the cross 29 will be pushed to move downward, and the return spring 32 will be compressed, at this time, the inclined surface of the bottom end of the cross 29 will extrude the inclined surface of the side close to the limiting block 28, and thus the limiting block 28 can only slide horizontally, so 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 is inserted into the corresponding limiting groove 30, at the same time, 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 thus the position of the fixing block 6 is limited (it should be noted that since the fixing block 6 is inserted into the rectangular groove 35 through the rectangular block 26, it will not be affected when the insertion rod 10 is inserted and locked, this step is only to limit the upward pulling of the fixing block 6);

[0052] 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.

[0053] 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.

[0054] The above shows and describes the basic principles, main features and advantages of the present application.

[0055] 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.
