Description

Technical Field

[0001] This application relates to the field of testing oil storage tank equipment, and in particular to a testing device for a foam generator in an oil storage tank. Background Technology

[0002] As a key component of the fire safety system for oil storage tanks, foam generators can mix foam liquid with water to generate foam when a fire occurs. The foam is then sprayed onto the oil surface through pipelines to suppress and extinguish the fire by isolating it from the air, effectively protecting the safety of the oil storage tank and the oil products, and reducing disaster losses.

[0003] Reference Figure 1 and Figure 2 The foam generator 900 of the oil storage tank 800 is typically installed on the side wall of the oil storage tank 800 at a relatively high position, usually below the top platform 810 of the oil storage tank. The foam generator 900 of the oil storage tank 800 includes a generator body 910 and a cover plate 920. The generator body 910 has an opening at the top, and the cover plate 920 is detachably connected to the top of the generator body 910 by bolts. The cover plate 920 is used to seal the top opening of the generator, and a lifting ring 921 is connected to the top of the cover plate 920. A support ring 930 is connected inside the generator body 910. A glass plate 940 is located on the top of the support ring 930, and a pressure ring 950 is located on the top of the glass plate 940. The pressure ring 950 is detachably connected to the support ring 930 by bolts, and connecting rings 951 are connected to both ends of the pressure ring 950 radially.

[0004] Regarding the aforementioned technologies, when inspecting a foam generator, workers need to descend from the top of the oil storage tank to a designated position via a lifting platform to inspect the foam generator. This process is costly and poses safety hazards. Utility Model Content

[0005] To reduce maintenance costs and operational safety risks, this application provides a detection device for foam generators in oil storage tanks.

[0006] The detection device for foam generators in oil storage tanks provided in this application adopts the following technical solution:

[0007] A detection device for a foam generator in an oil storage tank includes a main rod, a sleeve connected to the main rod, a top cover retrieval component, a glass retrieval assembly, and a camera. The sleeve is located at one end of the main rod and is used to connect to a bolt head. The main rod rotates, causing the sleeve to rotate the bolt. The camera is used to photograph the inner wall of the generator body. The top cover retrieval component is used to move the cover plate, and the glass retrieval assembly is used to move the glass plate.

[0008] By adopting the above technical solution, during use, the operator holds the main rod, connects the sleeve to the bolt head on the cover plate, rotates the main rod, causing the sleeve to rotate and thus remove the bolt from the cover plate. After the bolt is removed, the cover plate is moved by the cover plate moving component, opening the top opening of the generator body. Then, the glass plate is removed from the generator body by the glass removal component, making it easier for the imaging component to enter the generator body and observe the situation inside the generator body. The main rod extends the operating length, reducing the need for operation with a lifting platform, thereby reducing inspection costs and safety risks.

[0009] Optionally, the top cover removal component is a hook, which is used to hook the lifting ring.

[0010] By adopting the above technical solution, when in use, the hook is engaged with the lifting ring on the top of the cover plate, and the operator pulls the main rod to move the cover plate, thereby opening the top opening of the generator body, improving the convenience and safety of disassembling and assembling the cover plate.

[0011] Optionally, one end of the main rod is connected to an installation cylinder, and one end of the hook is inserted into the installation cylinder.

[0012] By adopting the above technical solution, the hook is inserted into the mounting cylinder during use, thereby stably connecting to the periphery of the main rod. When the hook is not needed, it can be removed, reducing the overall size of the device. If the hook is damaged, it can be replaced individually without replacing the entire device, thereby reducing maintenance costs and improving the flexibility of the device.

[0013] Optionally, the mounting cylinder is hinged to the main rod, which is connected to a locking element for locking the hook to the main rod.

[0014] By adopting the above technical solution, when disassembling the bolt, the hook can be rotated to fold, thereby reducing the interference caused by the hook during operation. When using the hook, the locking device locks the hook to the main rod, improving the stability of the hook and the main rod during use.

[0015] Optionally, the glass picking assembly includes a suction cup and a pressure ring moving component, wherein the suction cup is used to pick up the glass plate and the pressure ring moving component is used to move the pressure ring.

[0016] By adopting the above technical solution, during use, the bolts on the pressure ring are removed by the sleeve, and the pressure ring moving part drives the pressure ring to move, which facilitates the removal of the glass plate. The glass plate is picked up by the suction cup and moved, which minimizes the risk of the glass plate falling and getting damaged, and improves the stability of the disassembly and assembly of the internal components of the generator body.

[0017] Optionally, the pressure ring moving component includes a rotating rod and a support rod, with two rotating rods and two support rods. Each support rod is connected to one end of the rotating rod. The support rod is used to hook the connecting ring. The two rotating rods are hinged to each other. The rotating rod rotates and drives the support rod to pass through or disengage from the connecting ring.

[0018] By adopting the above technical solution, during use, the bolts on the pressure ring are removed using a sleeve. The operator takes the rotating rod and moves it so that the support rod is close to the pressure ring. The two rotating rods are rotated to drive the support rod through the connecting ring. After the support rod passes through the connecting ring, the rotating rod is moved, and the rotating rod drives the support rod to move. The pressure ring follows the support rod to move, thereby moving the pressure ring away from the generator body. Rotating the rotating rod moves the support rod away from the connecting ring, causing the pressure ring to detach from the support rod, thus facilitating the disassembly and assembly of the pressure ring.

[0019] Optionally, a first spring is provided between the rotating rods. The first spring is used to drive the rotating rod to rotate and drive the support rod to disengage from the connecting ring.

[0020] By adopting the above technical solution, when in use, rotating the rotating rod causes the end of the rotating rod away from the support rod to move closer to each other, causing the first spring to deform, thereby driving the support rod to move and pass through the connecting ring. When the rotating rod is released, the first spring returns to its shape and drives the rotating rod to rotate, thereby driving the support rod away from the connecting ring, thus making it easier to remove the pressure ring from the support rod.

[0021] Optionally, the sleeve is connected to the main rod via a universal joint, with one end of the universal joint connected to the main rod and the other end connected to the sleeve.

[0022] By adopting the above technical solution, the universal joint can flexibly adjust the angle of the sleeve during use, so that the sleeve can be adapted to bolts installed at different positions on the foam generator. This avoids the situation where the sleeve cannot connect to the bolt head due to angular deviation between the bolt and the sleeve, thus improving the adaptability of the device.

[0023] Optionally, the sleeve includes a first sleeve and a second sleeve, one end of the first sleeve is connected to a universal joint, the other end of the first sleeve is threadedly connected to the second sleeve, and the end of the second sleeve away from the first sleeve is used to connect to the bolt head.

[0024] By adopting the above technical solution, the second cylinder is prone to wear after long-term use, and the second cylinder is threadedly connected to the first cylinder, which facilitates the replacement of the second cylinder.

[0025] Optionally, a handle is attached to one end of the main rod.

[0026] By adopting the above technical solution, when in use, the operator holds the handle to operate the main rod. The handle provides a stable force point, which facilitates the rotation of the main rod to disassemble or assemble bolts or lift parts, thereby reducing hand fatigue and improving the stability and convenience of operation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. In use, the operator holds the main rod, connects the sleeve to the bolt head on the cover plate, rotates the main rod, drives the sleeve to rotate, and thus rotates the bolt head, thereby removing the bolt from the cover plate. After the bolt is removed, the cover plate is moved by the cover plate moving component, which opens the top opening of the generator body. Then, the glass plate is removed from the generator body by the glass removal component, which makes it easier for the imaging component to enter the generator body and observe the situation inside the generator body. The main rod extends the operating length, reducing the need for high-altitude operations with the help of a lifting platform, thereby reducing the detection cost and safety risks.

[0029] 2. When in use, the hook is attached to the lifting ring on the top of the cover plate. The operator pulls the main rod to move the cover plate, which opens the top opening of the generator body, improving the convenience and safety of the cover plate disassembly and assembly.

[0030] 3. In use, remove the bolts on the pressure ring using the sleeve. The operator takes the rotating rod and moves it so that the support rod is close to the pressure ring. Rotate both rotating rods to drive the support rod through the connecting ring. After the support rod passes through the connecting ring, move the rotating rod. The rotating rod drives the support rod to move, and the pressure ring follows the support rod to move away from the generator body. Rotate the rotating rod to move the support rod away from the connecting ring, so that the pressure ring is detached from the support rod, which facilitates the disassembly and assembly of the pressure ring.

The hook 700 is detachably connected to the mounting cylinder 130, which facilitates the storage of the hook 700 and reduces the space occupied by the device.

[0043] Reference Figure 3The glass handling assembly 300 includes a suction cup 310 and a movable pressure ring 950. The movable pressure ring 950 includes two rotating rods 321 and two support rods 322, with the two rotating rods 321 hinged together. Each support rod 322 is connected to the end of each rotating rod 321 near the glass plate 940, with its length aligned radially with the glass plate 940, and connected to the side of the rotating rod 321 away from the other rotating rod 321. A first spring 323 is provided between the rotating rods 321, with both ends connected to the two rotating rods 321, and the first spring 323 is used to drive the rotating rods 321 to rotate and to drive the two support rods 322 closer together. The suction cup 310 is used to pick up the glass plate 940. The suction cup 310 is connected to the mounting rod 311, and the mounting rod 311 is connected to the extension rod 312. The mounting rod 311 is detachably connected to the extension rod 312 via a clamp 313, which is also connected to the extension rod 312 and fitted onto the mounting rod 311. After removing the bolt from the pressure ring 950 using the sleeve 200, the rotating rod 321 is rotated so that the support rod 322 passes through the connecting ring 951, thereby facilitating the removal of the pressure ring 950 from the generator body 910. Then, the suction cup 310 picks up the glass, thereby facilitating the removal of the glass plate 940 from the generator body 910.

[0044] Reference Figure 3 The camera assembly 400 includes a lens 410, a connecting cable 420, and a mobile phone 430.

The lens 410 is located at one end of the main pole 100 with a plug 110, and the mobile phone 430 is located at the end of the main pole 100 near the mounting slot 120. The connecting cable 420 is detachably connected to the main pole 100 via several ring clamps 440.

[0045] The implementation principle of the detection device for a foam generator in an oil storage tank according to an embodiment of this application is as follows: In use, the sleeve 200 is extended by the main rod 100 and brought close to the top bolt head of the cover plate 920, so that the bolt head is embedded in the connecting groove 221. The main rod 100 is rotated by the ratchet wrench 600, thereby driving the sleeve 200 to rotate the bolt, and thus removing the bolt from the cover plate 920. After the bolt is removed, the connecting rod 720 is inserted into the mounting cylinder 130 and rotated, so that the connecting rod 720 is engaged with the buckle 140, thereby completing the installation of the hook 700. Moving the main rod 100 drives the hook 700 to move, so that the hook 700 is close to the lifting ring 921 and hooks the lifting ring 921, thereby facilitating the operator to move the cover plate 920 away from the generator body 910.

[0046] After removing the bolts on the pressure ring 950 using the sleeve 200, move the rotating rod 321 so that the support rod 322 approaches the pressure ring 950. Rotate the rotating rod 321 so that the end of the rotating rod 321 away from the support rod 322 moves closer to each other, thereby causing the support rod 322 to pass through the connecting ring 951. Move the rotating rod 321 and move the support rod 322 and the pressure ring 950 away from the generator body 910. Move the extension rod 312 to move the suction cup 310 closer to the glass plate 940. The suction cup 310 adheres to the glass plate 940. Moving the extension rod 312 in this way moves the suction cup 310 and the glass plate 940 away from the generator body 910. After the glass plate 940 is removed from the generator, the connecting wire 420 is installed on the main rod 100 through the ring clamp 440. The main rod 100 is then moved to drive the lens 410 deeper into the generator body 910, so that the operator can observe and photograph the situation inside the generator body 910. The main rod 100 extends the operating length, reducing the need for operation with a lifting platform, thereby reducing detection costs and safety risks.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
