Description

Technical Field

[0001] The utility model relates to the technical field of high - and medium - frequency lightning shunt for floating - roof storage tanks, and specifically relates to a high - and medium - frequency lightning shunt for floating - roof storage tanks. Background Technique

[0002] The external floating roof of a storage tank is usually used in an open - top cylindrical steel storage tank for storing volatile petroleum products such as crude oil, gasoline or kerosene; a floating - roof storage tank refers to an upright cylindrical storage tank with a floating roof cover. It is also called an "external floating - roof storage tank". The roof of the storage tank floats on the liquid surface and rises and falls with the liquid level. The floating - roof structure includes single - deck, double - deck and shallow - deck types, etc.; the floating roof plays a protective role for the uppermost liquid surface of the oil, and can avoid the evaporation of the oil. In order to ensure that the floating roof can move up and down with the oil, there is usually a gap between the floating roof and the inner wall of the oil storage tank.

[0003] However, during the use of the floating roof, some static electricity will be generated, and there is also a risk of lightning strike. The lightning shunt is a connection structure between the floating roof and the inner wall of the oil storage tank to facilitate the discharge of the static electricity of the floating roof. In the application process of some existing lightning shunt structures, problems such as the deformation of the pressing piece of the shunt not in contact, and the micro - deformation of the storage tank wall and the floating disk not in contact may occur, resulting in unstable electrical connection.

[0004] In view of the above problems, the present utility model is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a high - and medium - frequency lightning shunt for floating - roof storage tanks to solve the problems mentioned in the background technique.

[0006] To solve the above - mentioned technical problems, the present utility model provides the following technical solutions.

[0007] The present utility model provides a high - and medium - frequency lightning shunt for floating - roof storage tanks, including a bottom plate, a strip plate and a spring. Through holes penetrating the bottom plate are arranged at four corner positions on the upper surface of the bottom plate;

[0008] Two rotating seats are symmetrically arranged on the upper surface of the bottom plate. The lower end of the strip plate is rotatably installed between the two rotating seats, and a roller is arranged at the upper end of the strip plate;

[0009] A central groove is arranged at the central position on the upper surface of the bottom plate. One end of the central groove is located below the strip plate. A plurality of strip rods are arranged on two opposite inner walls at the end of the central groove far from the strip plate. A plurality of hanging blocks are arranged on the lower surface of the lower end of the strip plate, and a hanging hole penetrating the hanging block is arranged at the center of the hanging block;

[0010] One end of the spring is provided with a first hook, and the other end is provided with a second hook. The spring is located in the central groove. The first hook is hung on the strip bar, and the second hook is hung in the hanging hole.

[0011] Preferably, the central grooves are evenly distributed at equal intervals along the length direction of the bottom plate. There are three strip bars, and the three strip bars are evenly distributed at equal intervals along the length direction of the central groove. The three strip bars are all parallel to each other.

[0012] Preferably, the lower surface of the lower end of the strip plate is semicircular. There are three hanging blocks, and the three hanging blocks are evenly distributed at equal intervals along the semicircular path of the lower surface of the strip plate.

[0013] Preferably, the width of the lower half of the strip plate is greater than the width of the upper half. A wheel groove is provided at the upper end of the strip plate, and the roller is installed in the wheel groove through a rotating shaft.

[0014] Preferably, the strip plate inclines towards the side of the bottom plate away from the spring.

[0015] Preferably, the central axis of the strip plate is aligned with the axis in the length direction of the bottom plate, and the central axis of the strip plate is aligned with the axis in the length direction of the central groove.

[0016] Preferably, the two sides of the spring are abutted against two opposite inner walls of the central groove.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] Four bottom plates are installed in a surrounding shape on the upper surface of the floating roof. By passing bolts through the through holes and then screwing them into the floating roof, the installation can be achieved. The second hook of the spring has a pulling force on the hanging block, so that the strip plate can be rotated to an inclined position;

[0019] For the inclined strip plate, the roller at the front end just fits against the inner wall of the storage tank. The roller can rotate. When the floating roof floats above the liquid level in the storage tank, the roller can roll up and down along with the inner wall of the storage tank; the roller, the strip plate, the rotating seat and the bottom plate are all made of conductive materials, and the static electricity generated by the floating roof can be quickly transmitted to the storage tank through the bottom plate, the rotating seat, the strip plate and the roller, and then transmitted to the ground surface;

[0020] Under the pulling action of the spring, the strip plate and the roller incline towards the storage tank. When the roller always abuts against the inner wall of the storage tank, even if the floating roof has displacements in the left-right, front-back directions, the roller can always abut against the inner wall of the storage tank, and the conductivity between the floating roof and the storage tank is always kept good, making the floating roof storage tank safer during use.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0027] As Figures 1-3 shown, a high-frequency and medium-frequency lightning shunt for a floating roof storage tank includes a bottom plate 1, a strip board 13 and a spring 2. Through holes 11 penetrating the bottom plate 1 are provided at the four corner positions on the upper surface of the bottom plate 1. Bolts pass through the through holes 11 and are then screwed into the upper surface of the floating roof 3, so that the entire device can be fixed on the upper surface of the floating roof 3;

[0028] Two rotating bases 12 are also symmetrically provided on the upper surface of the bottom plate 1. The lower end of the strip board 13 is rotatably installed between the two rotating bases 12, and a roller 14 is provided at the upper end of the strip board 13, and the roller 14 can rotate;

[0029] A central groove 15 is provided at the central position on the upper surface of the bottom plate 1. One end of the central groove 15 is located below the strip board 13. A plurality of strip rods 16 are provided on the two opposite inner walls at the end of the central groove 15 away from the strip board 13. A plurality of hanging blocks 17 are provided on the lower surface of the lower end of the strip board 13, and a hanging hole 18 penetrating the hanging block 17 is provided at the center of the hanging block 17;

[0030] One end of the spring 2 is provided with a first hook 21, and the other end is provided with a second hook 22. The spring 2 is located in the central groove 15. The first hook 21 is hung on the strip rod 16, and the second hook 22 is hung in the hanging hole 18. That is, the spring 2 has a certain pulling force on the hanging block 17, so that the strip board 13 can be pulled to rotate the strip board 13.

[0031] The central grooves 15 are evenly distributed at equal intervals along the length direction of the bottom plate 1. There are three strip rods 16, and the three strip rods 16 are evenly distributed at equal intervals along the length direction of the central groove 15. The three strip rods 16 are all parallel to each other. The first hook 21 can be hung on the strip rods 16 at different positions, so that the pulling force on the lower end of the strip board 13 can be adjusted.

[0032] The lower surface of the lower end of the strip board 13 is semicircular. There are three hanging blocks 17, and the three hanging blocks 17 are evenly distributed at equal intervals along the semicircular path of the lower surface of the strip board 13. The second hook 22 can be hung in the hanging blocks 17 at different positions to adjust the pulling force on the lower end of the strip board 13; this can make the roller 14 always lean against the inner wall of the storage tank 4.

[0033] The width of the lower half of the strip board 13 is greater than the width of the upper half. A wheel groove is provided at the upper end of the strip board 13, and the roller 14 is installed in the wheel groove through a rotating shaft.

[0034] The strip board 13 is inclined towards the side of the bottom plate 1 away from the spring 2.

[0035] The central axis of the strip board 13 is aligned with the axis in the length direction of the bottom plate 1, and the central axis of the strip board 13 is aligned with the axis in the length direction of the central groove 15. That is, the spring 2 is located below the central axis of the strip board 13, so that the pulling force of the spring 2 on the strip board 13 is relatively uniform.

[0036] Both sides of the spring 2 are against the two opposite inner walls of the central groove 15, and the spring 2 cannot move left and right, so the spring 2 is relatively stable during operation.

[0037] In summary: The four bottom plates 1 are installed on the upper surface of the floating roof 3 in a surrounding shape. Pass the bolts through the through holes 11 and then screw them into the floating roof 3 to complete the installation. The second hook 22 of the spring 2 has a pulling force on the hanging block 18, so that the strip board 13 can be rotated to an inclined position;

[0038] For the inclined strip board 13, the roller 14 at the front end just fits against the inner side wall of the storage tank 4, and the roller 13 can rotate. When the floating roof 3 floats above the liquid level in the storage tank 4, the roller 13 can roll up and down along with the inner side wall of the storage tank 4; The roller 14, the strip board 13, the swivel base 12 and the bottom plate 1 are all made of conductive materials. The static electricity generated by the floating roof 3 can be quickly transmitted to the storage tank 4 through the bottom plate 11, the swivel base 12, the strip board 13 and the roller 14, and then transmitted to the ground surface;

[0039] Under the pulling action of the spring 2, the strip board 13 and the roller 14 incline towards the storage tank 4. When the roller 14 always abuts against the inner wall of the storage tank 4, even if the floating roof 3 has displacements in the left-right, front-back directions, the roller 14 can always abut against the inner wall of the storage tank 4, and the conductivity between the floating roof 3 and the storage tank 4 is always kept good, making the floating roof 3 and the storage tank 4 safer during use.
