[0035] Many specific details are described in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation disclosed below.

[0036] In the description of the present invention, it should be understood that the descriptions involving orientation, such as up, down, front, back, left, right, etc., the orientation or positional relationship indicated are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positioning protection mechanism or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] In the description of the present invention, reference terms such as "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present invention.

[0039] In order to fill the oil tank with barrier explosion-proof materials, in line with the principle of safety first, combined with the standards and specifications of relevant companies and relevant departments, the barrier explosion-proof technical transformation project for confined spaces, the requirement that personnel do not enter the tank to implement mechanical filling, according to the characteristics and features of the oil tank structure and barrier explosion-proof materials, considering that the barrier explosion-proof materials are round, their specific gravity is slightly higher than that of water, and they are easy to squeeze into the leak after being squeezed. For example, if the normal oil tank is stacked at a height of 2.2 meters to 3 meters, the single extrusion pressure per square meter on the side is not more than 15 kilograms, but after the water injection type oil is filled, the extrusion pressure will be greatly reduced. In summary, in order to ensure that the original operating procedures and functions are not changed after the installation of the barrier explosion-proof materials, the positioning protection mechanism of the utility model is specially designed.

[0040] See also Figure 1 As shown, the embodiment of the utility model discloses a positioning protection mechanism for filling barrier explosion-proof materials, comprising:

[0041] A shaft frame, wherein a continuous vertical space is formed in the shaft frame;

[0042] The filter screen or filter plate 1 is fixedly connected to the outer periphery of the shaft frame.

[0043] The positioning and protection mechanism disclosed in this embodiment can be stably arranged at the lower part of the manhole of the oil tank, and define a space in the oil tank to prevent the barrier explosion-proof material from entering, thereby avoiding the barrier explosion-proof material from affecting the normal use of the oil tank. At the same time, it can also support and position the material pipe used for transportation during the filling process of the barrier explosion-proof material.

[0044] In a specific embodiment, the positioning and protection mechanism is arranged at the lower part of the manhole 9 in the oil tank 10, and is used to position the material pipe for conveying the barrier and explosion-proof material during the process of filling the barrier and explosion-proof material into the oil tank 10, and is also used to prevent the barrier and explosion-proof material in the oil tank from entering the internal space of the positioning and protection mechanism after filling. Therefore, the gap between the filter screen or filter plate and the manhole and the bottom of the oil tank is smaller than the diameter of the barrier and explosion-proof material.

[0045] In some embodiments, the shaft framework comprises:

[0046] Longitudinal support members 2, at least two of which are used to longitudinally support and fix the positioning protection mechanism;

[0047] The transverse support members 3 are multiple in number, and each of the transverse support members is horizontally connected to the longitudinal support member.

[0048] Optionally, the longitudinal support and the transverse support are made of metal materials resistant to oxidation and corrosion. In order to achieve stable support and avoid the movement of the positioning protection mechanism in the oil tank, the material of the oil tank is considered to keep their oxidation points consistent. At the same time, due to the oxidation and corrosion of oil products, Q235.3×3 hot-dip galvanized flat iron can be used as the manufacturing material of the longitudinal support and the transverse support.

[0049] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the height of the longitudinal support member 2 is smaller than the inner diameter of the oil tank 10, and the difference between the two is 300-600 mm, and can be 500 mm. The cross-sections of the longitudinal support member and the transverse support member are square or circular, and the side length of the square or the diameter of the circle ranges from 20 mm to 50 mm. The shaft frame is cylindrical, and the diameter of the shaft frame is smaller than the diameter of the manhole. The height of the filter screen or filter plate is greater than the height of the shaft frame, the top of the filter screen or filter plate is engaged with the bottom of the manhole, and the bottom of the filter screen or filter plate is engaged with the bottom of the oil tank.

[0050] In a specific embodiment, the longitudinal and transverse support members are manufactured according to the measured inner diameter of the oil tank and the size of the manhole.

[0051] See also Figure 3 As shown, in an optional embodiment, the height of the longitudinal support member 2 is approximately the inner diameter of the oil tank minus 500mm, and the main support connected to the transverse support member 3 is the longitudinal support member 2, which is the height of the oil tank minus 500mm. Optionally, the oil tank with a height lower than 2.2m is connected with 4 transverse support members 3, and the oil tank with a height higher than 2.2m is connected with 5 transverse support members 3. One transverse support member 3 is connected to each end of the longitudinal support member 2, and the other transverse support members 3 are connected to the middle of the longitudinal support member. When connecting, pay attention to connecting the longitudinal support member 3 to the inner side of the circular ring formed by the transverse support members. Preferably, the connecting ends of the circular ring are arranged on the same vertical line.

[0052] See also Figure 4As shown, the diameter of the ring formed by the transverse support member is 20mm smaller than the inner diameter of the manhole, and the cutting length is the inner diameter of the manhole minus 20mm multiplied by the pi plus 10mm, which is the actual length. The first connecting hole that is rounded at 10mm at both ends is used to form a ring. When the overall diameter of the positioning protection mechanism is not greater than 500mm, four second connecting holes can be set to connect the four longitudinal support members.

[0053] In some embodiments, the connection between the longitudinal support member 2 and the transverse support member 3 and between the shaft frame and the filter screen or filter plate 1 is any one of the following: welding, threaded connection or riveting.

[0054] Specifically, considering the special environment and safety of the construction of gas stations or oil depots, it is not suitable to weld at the processing site, so a soft connection method can be used, such as drilling holes and then riveting or threading. Of course, if prefabrication is possible, welding can also be used for processing.

[0055] In some embodiments, the filter plate 1 is an aluminum punching plate, the diameter of the punching holes on the filter plate 1 is smaller than the diameter of the barrier explosion-proof material, and the thickness of the filter plate 1 ranges from 0.5 to 3 mm.

[0056] Optionally, taking into account the extrusion force exerted on the filter screen or filter plate 1 in the oil tank, it is convenient to remove the positioning protection mechanism from the oil tank later. The friction force formed by the mesh surface of the filter screen and the surface structure of the explosion-proof material is greater, so an aluminum punching plate with a thickness of more than 0.7 is preferred.

[0057] In a specific embodiment, in combination Figure 5 As shown, in order to fit the bottom of the filter plate to the bottom of the oil tank, firstly, the aluminum punching plate with a width of 100mm is designed and cut. One end is riveted to the longitudinal support, and it is wrapped tightly along the column of the shaft frame and fixed with aluminum rivets. When riveting, the aluminum punching plate is 500mm higher than the shaft frame, and the other end is 100mm higher. An arc is opened at the bottom of the shaft frame according to the diameter of the oil tank to ensure that the shaft goes down to the bottom of the oil tank and the oil tank arc is consistent. In the arc shearing method, the 100mm extra when cutting the material is left with 50mm at both ends of the material, and the remaining width is divided into 4 equal parts. A circle is drawn on the center line of the first and third equal parts according to the radius of the oil tank. The arc width ends at the equal division line, and the second and fourth equal parts are connected with an arc.

[0058] In some embodiments, in combination Figure 1 As shown, a filter screen 4 is further provided at the bottom of the filter screen or filter plate 1. The filter screen 4 is used to prevent solid matter at the bottom of the oil tank from entering the internal space of the positioning protection mechanism.

[0059] In some embodiments, see Figure 6As shown, an opening 8 is provided on the upper portion of the filter screen or filter plate 1, and the opening is used for a material pipe for conveying the barrier explosion-proof material to pass through.

[0060] In some embodiments, the number of the openings 8 is two, which are symmetrically arranged on the positioning protection mechanism, and the openings 8 are formed by cutting out parts of the filter screen or filter plate 1, combined with Figure 6 As shown, the bottom of the cut portion is connected to the filter screen or filter plate 1.

[0061] Optionally, the opening 8 is a square opening or a circular opening, and the side length of the square opening or the diameter of the circular opening is greater than the diameter of the material pipe for conveying the barrier and explosion-proof material.

[0062] In a specific embodiment, two openings of 200×200 mm are opened from the lowest point of the bottom of the filter plate 4 (i.e., the lowest point of the inner diameter of the oil tank) upwards near the manhole. When opening, the upper, left and right parts of the opening position are cut open, and the bottom side cannot be cut open. These two openings are prefabricated openings for placing the material pipe when the explosion-proof material is filled on the left and right. After the explosion-proof material is filled, the cut filter plate is pushed inwards, and another filter plate is inserted at the upper end to ensure that the explosion-proof material does not fall out.

[0063] In this embodiment, there is no gap between the positioning protection mechanism and the manhole, or the gap cannot pass through the explosion-proof material, and the positioning protection mechanism cannot shake in the manhole, so the positioning protection mechanism is stabilized to ensure that the positioning protection mechanism will not deviate.

[0064] Another aspect of the embodiment of the present utility model provides an oil tank 10, in which a positioning protection mechanism according to any one of the above-mentioned embodiments is arranged.

[0065] It should be noted that although the utility model is disclosed as above in the form of a preferred embodiment, it is not intended to limit the utility model. Any technical personnel in this field may make possible changes and modifications without departing from the spirit and scope of the utility model. Therefore, the scope of protection of the utility model shall be based on the scope defined by the claims of the utility model.
