Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical storage tanks, in particular to a fire water spray cooling device for a petrochemical storage tank. Background Art

[0002] An oil storage tank is a container for storing oil products. It is the main facility of an oil depot and the oil source interface of an oil pipeline in pipeline transportation. Metal oil tanks are widely used due to their low cost, low leakage, convenient construction and easy maintenance. At present, the method for cooling oil storage tanks is generally to use fire water to spray on the surface of the oil storage tank to achieve the purpose of cooling. Therefore, an existing petrochemical storage tank fire water spray cooling device has been continuously innovated and developed. Therefore, it can be seen that the current petrochemical storage tank fire water spray cooling device basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN220513307U discloses: "The technical field of fire water spray cooling device for petrochemical storage tanks, and discloses a fire water spray cooling device for petrochemical storage tanks, including a device body; and a connecting assembly arranged on the device body; by pulling the lifting of the partition plate connected to both sides of the protective cover, the water sprayed on the petrochemical storage tank is prevented from splashing, and a fixed block is fixedly connected to the front and rear ends of the upper end of the partition plate to prevent the partition plate slidably connected to the inner wall of the limit sliding opening opened in the device body from sliding out; a fixed frame is fixedly connected to the top of the device body, and a compression sleeve is provided on the outer wall of the sliding rod slidably connected to the inner wall of the limit hole opened in the fixed frame. The connecting spring of the compressed connecting spring pushes the push block connected on the inner side to move inward, and the moving push block drives the fixedly connected sliding rod to slide into the inner wall of the limiting hole opened in the partition plate, so as to limit the connected partition plate, which is convenient for effectively avoiding a large amount of spraying water splashing when the petrochemical storage tank is sprayed with fire water for cooling. By setting the lifting and lowering of the partition plate connected to both sides of the protective cover with traction, the water sprayed on the petrochemical storage tank can be avoided from splashing. Fixed blocks are fixedly connected to the front and rear ends of the upper end of the partition plate to prevent the partition plate connected to the inner wall of the limiting sliding port opened in the device body from sliding out, which is convenient for effectively avoiding a large amount of spraying water splashing when the petrochemical storage tank is sprayed with fire water for cooling.

[0004] However, when the connecting assembly is used to spray the storage tank, the storage tank needs to be lifted and placed inside the connecting assembly. Since the storage tank is heavy, it is troublesome to lift it. When the storage tank is placed in the connecting assembly, only the upper and lower ends of the storage tank can be exposed to the outside, resulting in the oil extraction valve being blocked by the connecting assembly and difficult to open. The storage tank can only be lifted down again. The process of cooling and extracting the oil requires repeatedly lifting the storage tank, which consumes too much physical energy of the staff. In addition, there is a risk of the storage tank accidentally rupturing during the process of lifting the storage tank multiple times. Therefore, a petrochemical storage tank fire water spray cooling device is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a fire water spray cooling device for a petrochemical storage tank, so as to solve the problem in the above background technology that the oil extraction valve is blocked by the connecting assembly and is difficult to open, and the storage tank can only be lifted down again.

[0015] 1. Through the use of the curtain, after the petrochemical storage tank is placed on the base, the position of the curtain can be pushed so that the curtain covers the storage tank, so as to facilitate spraying and cooling the storage tank. When the storage tank needs to be used, there is no need to lift it down. Push the curtain in the opposite direction to pile the curtains together. At this time, the area covered by the storage tank is smaller, which makes it easier to use. This device does not need to lift the storage tank repeatedly, and the storage tank can be used on the base, which shortens the operating steps of the staff and reduces the risk of the storage tank being touched and broken, thereby protecting the storage tank.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , 2 and Figure 4 , an embodiment provided by the utility model:

[0025] A fire water spray cooling device for a petrochemical storage tank comprises a base 1, a delivery pipe 2 is fixedly connected to the front of the base 1, a water pump 3 is installed at the bottom end of the delivery pipe 2, and a water spray box 4 is fixedly connected to the top end of the delivery pipe 2;

[0026] The shielding device includes a fixed rod 5, which is fixedly connected to the inner wall of the front side of the base 1, the top of the fixed rod 5 is fixedly connected to a top cover 6, the inner wall of the top cover 6 is slidably connected to a first pulley 7, the middle of the first pulley 7 is rotatably connected to a first connecting block 8, the bottom of the first connecting block 8 is fixedly connected to a connecting rod 9, the bottom end of the connecting rod 9 is fixedly connected to a second connecting block 10, the left and right sides of the second connecting block 10 are rotatably connected to second pulleys 11, and the surface of the second pulley 11 is slidably connected to the inner wall of the base 1, the top of the water spray box 4 is fixedly connected to a connecting shaft 12, and the top of the connecting shaft 12 is fixedly connected to the bottom of the top cover 6, the surface of the connecting shaft 12 is rotatably connected to a connecting rod 13, and the front end of the connecting rod 13 is fixedly connected to the top of the connecting rod 9, and the surfaces of the fixed rod 5 and the connecting rod 9 are both fixedly connected to a curtain 14.

[0027] When covering the petrochemical storage tank with the curtain 14, the petrochemical storage tank is lifted to the top of the base 1, and water is poured into the inner wall of the base 1, and then the connecting rod 9 is pushed, so that the connecting rod 9 drives the first connecting block 8 and the first pulley 7 at the top to slide on the inner wall of the top cover 6, and the connecting rod 9 drives the second connecting block 10 and the second pulley 11 at the bottom to slide on the inner wall of the base 1, and the connecting rod 9 drives the connecting rod 13 to rotate on the surface of the connecting shaft 12, so that the connecting rod 9 drives the curtain 14 to move and cover the surface of the petrochemical storage tank. At this time, the water pump 3 is powered on, so that the water pump 3 draws the water in the base 1 into the water pump 3 and pours it into the delivery pipe 2, so that the water enters the water spray box 4 through the delivery pipe 2 and is sprayed from the nozzle, and the water is sprayed on the surface of the petrochemical storage tank. The curtain 14 intercepts the splashing water to reduce the waste of water splashing. After the petrochemical storage tank is cooled, the connecting rod 9 is pushed in the opposite direction, so that the curtain 14 is concentrated and accumulated. At this time, the petrochemical storage tank is exposed to the outside again, so that it is convenient to use the petrochemical storage tank.

[0028] See also Figure 1 , 3 and Figure 5 , an embodiment provided by the utility model:

[0029] A plurality of support rods 15 are fixedly connected to the top of the base 1 , and a bottom plate 16 is fixedly connected to the inner wall of the top of the base 1 , and the bottom plate 16 is hollow.

[0030] When water resources are recycled through the bottom plate 16, the water is sprayed on the petrochemical storage tank and flows to the bottom plate 16. The water flows back into the base 1 through the bottom plate 16 to facilitate the water pump 3 to pump out the water again and spray it again.

[0031] Furthermore, a drain pipe 17 is fixedly connected to the front of the base 1, a rotating rod 18 is rotatably connected to the top of the inner wall of the drain pipe 17, a ball valve 19 is fixedly connected to the bottom end of the rotating rod 18, and the bottom end of the ball valve 19 is rotatably connected to the inner wall of the drain pipe 17, and a rotating disk 20 is fixedly connected to the top end of the rotating rod 18.

[0032] When draining the water in the base 1 through the drain pipe 17, the rotating disk 20 is rotated, so that the rotating disk 20 drives the rotating rod 18 at the bottom to rotate, and the rotating rod 18 drives the ball valve 19 at the bottom to rotate, so that the ball valve 19 opens, so that the dirty water can be discharged through the drain pipe 17 to facilitate the filling of clean water.

[0033] Furthermore, a connecting pipe 21 is fixedly connected to the left side of the base 1 , and a connecting ring 22 is rotatably connected to the surface of the connecting pipe 21 .

[0034] When connecting the external water pipe through the connecting ring 22, the external water pipe is placed on the connecting ring 22, and then the connecting ring 22 is rotated so that the water pipe is threadedly connected to the inner wall of the connecting ring 22, so that the water in the external water pipe can flow into the base 1 through the connecting pipe 21.

[0035] Working principle: thread the external water pipe to the connecting ring 22, then pour the fire water into the base 1, then place the petrochemical storage tank on the top of the bottom plate 16 on the base 1, and then push the connecting rod 9 to make the curtain 14 slide on the top of the base 1, so that the curtain 14 slides and covers the surface of the delivery pipe 2 and the support rod 15, and covers the petrochemical storage tank, and then the water pump 3 is powered on, so that the water pump 3 draws water in the base 1 and sprays it from the nozzle of the water spray box 4, so that the water is sprayed on the top of the petrochemical storage tank, and the water flows through the surface of the petrochemical storage tank to the top of the bottom plate 16. At this time, the curtain 14 intercepts the splashing water to prevent the water from splashing and wasting. The water flows down to the base 1 through the water flow holes between the bottom plate 16, so that the water can be sprayed again through the water pump 3. When the water is used too much and becomes dirty, the rotating disk 20 can be turned to open the ball valve 19, so that the water is discharged from the drain pipe 17.
