Abstract
Description
Technical Field
[0001] The utility model relates to the field of edge plate anti-corrosion equipment, in particular to an anti-corrosion structure for the edge plate of a storage tank. Background Technique
[0002] The edge plate of a storage tank refers to a structure made of special plates at the edge part of the storage tank, usually referring to the edge part of the bottom of the storage tank; the function of the edge plate of the storage tank is to strengthen the structural strength of the bottom of the storage tank and prevent the bottom of the storage tank from cracking or deforming due to the liquid pressure; at the same time, the edge plate of the storage tank can also play a sealing role to prevent liquid leakage.
[0003] The edge plate will be corroded during long-term use, thus reducing the strength of the edge plate and causing the tank body to leak. In order to prevent the edge plate from being corroded, anti-corrosion is carried out by applying mineral oil on the outside and cooperating with a high-density polyethylene jacket. However, the position where the high-density polyethylene jacket contacts the tank body is in an open state. During long-term use, the external environment is likely to penetrate to the edge plate position through the open position, resulting in the corrosion of the edge plate. Therefore, there is an urgent need for a device to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide an anti-corrosion structure for the edge plate of a storage tank to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-corrosion structure for the edge plate of a storage tank, including a concrete cushion block. A storage tank is arranged at the top end of the concrete cushion block. An edge plate is fixedly arranged at the bottom end of the storage tank. The outside of the concrete cushion block and the storage tank is covered with a high-density polyethylene jacket. A rubber gasket is arranged around the outside between the high-density polyethylene jacket and the storage tank. A rubber gasket is arranged around the outside between the high-density polyethylene jacket and the concrete cushion block. Both the concrete cushion block and the high-density polyethylene jacket are provided with fastening mechanisms for fastening the rubber gaskets. During use, the position between the concrete cushion block and the high-density polyethylene jacket is sealed by the rubber gasket, and at the same time, the position between the high-density polyethylene jacket and the storage tank is sealed by the rubber gasket, so as to prevent the external environment from penetrating through the contact gap position and causing the corrosion problem of the edge plate.
[0006] Preferably, the fastening mechanism includes a fixing plate, a first gear, a second gear, a rotating block, a screw rod, a positioning rod, a moving block and a fastening rope. The fixing plate is fixed at the top of the high-density polyethylene jacket. The first gear and the second gear are movably embedded on one side of the fixing plate. The screw rod is movably embedded between the fixing plates. The rotating block is fixed on one side of the first gear. The moving block is threadedly sleeved on the outer side of the screw rod. The positioning rod is fixed between the fixing plates. One side of the moving block is movably sleeved on the outer side of the positioning rod. The fastening rope is wound around the outer side of the rubber gasket. When the rubber gasket is loose during use, the rotating block is rotated at this time, so that the first gear rotates and drives the second gear to rotate, so that the screw rod rotates, so that the moving block moves along the screw rod, and the moving direction is away from the center position between the fixing plates. In this way, the fastening rope is pulled, so that the fastening rope tightens the rubber gasket, so as to maintain the sealing effect of the rubber gasket during long-term use.
[0007] Preferably, there are two fixing plates, which are symmetrically fixed on both sides of the top of the high-density polyethylene jacket.
[0008] Preferably, there are two screw rods. One side of one screw rod is fixed at the center position of the first gear, and one side of the other screw rod is fixed at the center position of the second gear.
[0009] Preferably, there are two moving blocks on each screw rod, and the screw rod is a positive and negative screw rod.
[0010] Preferably, one side of the fastening rope is wound and fixed on the moving block, and the other side is wound and fixed on the moving block on the same horizontal line. The first gear and the second gear are meshed.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] 1. When the present invention is in use, the position between the concrete cushion block and the high-density polyethylene jacket is sealed by the rubber gasket, and at the same time, the position between the high-density polyethylene jacket and the storage tank is sealed by the rubber gasket, so as to prevent the outside environment from infiltrating through the contact gap position and causing the corrosion problem of the edge plate;
[0013] 2. When the rubber gasket is loose during the use of the present invention, the rotating block is rotated at this time, so that the first gear rotates and drives the second gear to rotate, so that the screw rod rotates, so that the moving block moves along the screw rod, and the moving direction is away from the center position between the fixing plates. In this way, the fastening rope is pulled, so that the fastening rope tightens the rubber gasket, so as to maintain the sealing effect of the rubber gasket during long-term use.
