Description

Technical Field

[0001] The utility model relates to the technical field of safety devices, in particular to a safety device for a sulfuric acid storage tank. Background Art

[0002] Sulfuric acid storage tanks are tanks used to store sulfuric acid in the chemical and other industries. Currently, most sulfuric acid storage tanks in the domestic market or enterprises are made of fiberglass. Sulfuric acid is an active binary inorganic strong acid that can react with many metals. High concentrations of sulfur have strong water absorption and can be used as a dehydrating agent to carbonize carbohydrate-containing substances such as wood, paper, cotton and linen fabrics, and biological skins and flesh. When mixed with water, it also releases a large amount of heat energy. It is highly corrosive and oxidizing. However, during the transportation of existing sulfuric acid storage tanks, there is no good device to fix and protect the tank itself, making it easy for the tank to collide with the vehicle body during the transportation of the transport vehicle, resulting in the tank being easily damaged and causing sulfuric acid to overflow.

[0003] Chinese utility model CN220299328U is a safety device for a sulfuric acid storage tank. A fixed structure for the sulfuric acid storage tank is designed. The principle is to place the sulfuric acid storage tank on a base plate, then restrict the curved plate with a pressure rod, and finally drive the curved pressure block to fit tightly against the sulfuric acid storage tank by rotating the screw. After all the curved pressure plates are adjusted, the sulfuric acid storage tank can be restricted to reduce the possibility of movement and shaking.

[0004] However, the existing device needs to adjust each threaded rod when in use, which is cumbersome and time-consuming, affecting work efficiency. Therefore, a safety device with a faster limiting mode is designed to address the above-mentioned problems. Utility Model Content

[0032] Sulfuric acid storage tanks are tanks used to store sulfuric acid in the chemical and other industries. Currently, most sulfuric acid storage tanks in the domestic market or enterprises are made of fiberglass. Sulfuric acid is an active binary inorganic strong acid that can react with many metals. High concentrations of sulfur have strong water absorption and can be used as a dehydrating agent to carbonize carbohydrate-containing substances such as wood, paper, cotton and linen fabrics, and biological skins and flesh. When mixed with water, it also releases a large amount of heat energy. It is highly corrosive and oxidizing. However, during the transportation of existing sulfuric acid storage tanks, there is no good device to fix and protect the tank itself, making it easy for the tank to collide with the vehicle body during the transportation of the transport vehicle, resulting in the tank being easily damaged and causing sulfuric acid to overflow.

[0033] In the prior art, the sulfuric acid tank is placed on a base plate, a compression rod restrains the curved plate, and a screw is rotated to drive the curved pressure block into contact with the sulfuric acid tank. Once all the curved pressure plates are properly adjusted, the sulfuric acid tank is restrained, minimizing movement and shaking. However, the existing system requires adjusting each threaded rod, which is a cumbersome process and significantly delays work efficiency.

[0034] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a safety device for a sulfuric acid storage tank. When the sulfuric acid storage tank needs to be transported, the base 11 needs to be fixedly installed on a transport vehicle, and then the curved plate 12 is rotated to expose the inner side of the base 11. The sulfuric acid storage tank is placed on the base 11, and then the curved plate 12 is rotated to close it. It is only necessary to use the limiting component 13 to process one end of the curved plate 12 to limit it, slide the L-shaped plate 133 so that the slider 132 slides inside the chute 131, and slide the L-shaped plate 133 to the top of one end of the curved plate 12 to limit it. Then the double-headed motor 25 is connected to the external power supply to drive the threaded rod 26 to rotate. When the threaded rod 26 rotates, it will drive the two shells 23 closer. Because the inner side wall of the shell 23 is inclined, the inner side wall of the shell 23 will squeeze the connecting rod 21 during the movement so that the connecting rod 21 is inserted into the interior of the curved plate 12, thereby pushing the pressure plate 22 to limit the sulfuric acid storage tank and reduce the possibility of movement. At the same time, when the sulfuric acid storage tank is placed, the vertical rod 33 whose inner side wall is in contact with the sulfuric acid storage tank will be squeezed and retracted into the interior of the trough body 31, while the vertical rod 33 at both ends of the sulfuric acid storage tank that is not in contact with the sulfuric acid storage tank will be pushed out from the interior of the trough body 31 by the spring 32, which can limit the sulfuric acid storage tank from sliding on the inside of the base 11.

[0035] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0036] Combine Figures 1-4 , an embodiment of the present application provides a safety device for a sulfuric acid storage tank, comprising: a base 11 with a curved plate 12 rotatably provided on the top thereof, and the base 11 is used to place the sulfuric acid storage tank; a limiting component 13 is provided on one side of the base 11, for limiting the curved plate 12; a clamping component 2 is provided on the curved plate 12, and the clamping component 2 comprises: one end of a connecting rod 21 passes through the curved plate 12; a pressing plate 22 is provided at the bottom of the connecting rod 21; a shell 23 is provided on the outside of the curved plate 12; both ends of a horizontal plate 24 are connected to the curved plate 12; a double-headed motor 25 is provided at the top of the horizontal plate 24; a threaded rod 26 is provided on the output shafts at both ends of the double-headed motor 25, and one end passes through the shell 23 and is threadedly connected to the shell 23.

[0037] Specifically, the base 11 is installed and fixed on a transport vehicle and is used to place the sulfuric acid storage tank and transport the sulfuric acid storage tank.

[0038] During use, when the sulfuric acid storage tank needs to be transported, the base 11 needs to be fixedly installed on the transport vehicle, and then the curved plate 12 needs to be rotated to expose the inner side of the base 11, the sulfuric acid storage tank needs to be placed on the base 11, and then the curved plate 12 needs to be rotated to close it. It is only necessary to use the limiting component 13 to process one end of the curved plate 12 to limit it, and then connect the double-headed motor 25 to the external power supply to drive the threaded rod 26 to rotate. When the threaded rod 26 rotates, it will drive the two shells 23 closer. Because the inner side wall of the shell 23 is designed to be inclined, the inner side wall of the shell 23 will squeeze the connecting rod 21 during the movement so that the connecting rod 21 is inserted into the inside of the curved plate 12, thereby pushing the pressure plate 22 to limit the sulfuric acid storage tank and reduce the possibility of movement.

[0039] In some embodiments, the pressing assembly 2 further includes: one end of a limiting rod 27 passes through the shell 23 and is connected to the arc plate 12 .

[0040] The setting of the limiting rod 27 can ensure the stable movement of the housing 23 during use.

[0041] In some embodiments, the pressing assembly 2 further includes: a stopper 28 provided at one end of the threaded rod 26 and the limiting rod 27 .

[0042] During use, the threaded rod 26 can be prevented from being separated from the housing 23, and the limiting rod 27 can be prevented from being separated from the housing 23.

[0043] In some embodiments, the pressing assembly 2 further includes: a ball 29 disposed on the top of the connecting rod 21 .

[0044] During use, the arrangement of the ball 29 can reduce scratches when contacting the inner wall of the shell 23, thereby avoiding damage to the inner wall of the shell 23.

[0045] In some embodiments, the pressing assembly 2 further includes: a rubber strip 291 disposed at the bottom of the pressing plate 22 .

[0046] During use, the provision of the rubber strip 291 can increase the frictional force when in contact with the sulfuric acid storage tank, thereby making it difficult for the sulfuric acid storage tank to move on the base 11.

[0047] In some embodiments, the limiting component 13 includes: a slide groove 131 opened on one side of the base 11; a slider 132 slidably set inside the slide groove 131; an L-shaped plate 133 is set on one side of the base 11 and connected to the slider 132, and the top end can overlap with one end of the arc plate 12.

[0048] When in use, the L-shaped plate 133 can be slid to allow the slider 132 to slide inside the sliding groove 131, and the L-shaped plate 133 can be slid and overlapped to the top of one end of the arc-shaped plate 12 to restrict it.

[0049] In some embodiments, the limiting assembly 13 further includes a rubber bump 134 disposed on the L-shaped plate 133 .

[0050] During use, the rubber protrusion 134 can prevent the L-shaped plate 133 from being easily separated from one end of the arc-shaped plate 12 after the L-shaped plate 133 is overlapped with one end of the arc-shaped plate 12 , thereby ensuring the stability of the arc-shaped plate 12 .

[0051] In some embodiments, a telescopic assembly 3 is provided on the inner wall of the base 11, and the telescopic assembly 3 includes: a groove body 31 opened on the inner wall of the base 11; a spring 32 is provided inside the groove body 31; and the bottom end of the vertical rod 33 is inserted into the interior of the groove body 31 and connected to the spring 32.

[0052] During use, when placing the sulfuric acid storage tank, the vertical rod 33 whose inner side wall of the base 11 contacts the sulfuric acid storage tank will be squeezed and retracted into the interior of the trough body 31, while the vertical rod 33 at both ends of the sulfuric acid storage tank that does not contact the sulfuric acid storage tank will be pushed out from the interior of the trough body 31 by the spring 32, which can limit the sulfuric acid storage tank from sliding on the inside of the base 11.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.
