Description

Technical Field

[0001] This utility model relates to the field of standard oil sample technology, and more specifically, to a sealing device that can preserve standard oil samples for a long period of time. Background Technology

[0002] Standard oil, also known as "oil equivalent," is a unified unit of measurement for various energy sources based on its calorific value. Standard oil must be protected from light and heat and kept sealed during storage. Most existing standard oil storage tanks are opened and closed by rotating the sealing cap on top of the tank. However, during use, the threads on the inner wall of the sealing cap are prone to stripping after a long period of use, resulting in a poor seal. In addition, most existing storage tanks are equipped with an oil outlet pipe with a valve on the tank body. Standard oil samples are taken by opening the valve, but this method makes it difficult to control the amount of oil taken and easily leads to waste. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a sealing device for long-term preservation of standard oil samples, including an oil drum 10, multiple support legs 20 disposed outside the oil drum 10, and an oil inlet 50 disposed on the top of the oil drum 10. The oil drum 10 is provided with a sealing rod 30 and a housing 40. One end of the sealing rod 30 is provided with a sealing gasket 3001, and a fixing rod 3003 is disposed inside the sealing rod 30. A movable ring 3015 is disposed outside the fixing rod 3003, and multiple hinge rods 3004 are disposed outside the movable ring 3015. A limit block 3005 is disposed at the other end of the hinge rod 3004. Multiple limit grooves 3014 are opened on the oil drum 10, and all the multiple limit grooves 3014 are connected to the oil inlet 50.

[0030] The oil drum 10 has a double-layer design, with an insulation cavity formed between the inner and outer layers, which can provide insulation and is conducive to the long-term preservation of standard oil samples. The oil drum 10 is made of opaque material, and there are at least three support legs 20 to facilitate stable support of the oil drum 10.

[0031] Meanwhile, a support spring 3006 is provided on the outside of the fixing rod 3003, a push plate 3007 is provided on the outside of the fixing rod 3003, a plurality of connecting rods 3008 are provided on the top of the push plate 3007, a top plate 3009 is provided on the other end of the plurality of connecting rods 3008, and a threaded groove 3013 is provided on the top of the fixing rod 3003, and a lead screw 3011 is provided inside the threaded groove 3013.

[0032] In addition, the two ends of the hinge rod 3004 are rotatably connected to the movable ring 3015 and the limiting block 3005, respectively. The number of limiting grooves 3014 and limiting blocks 3005 are equal. The limiting blocks 3005 are inserted into the limiting grooves 3014 and are fitted with them with clearance. The insertion of the limiting blocks 3005 into the limiting grooves 3014 can fix the sealing rod 30. The sealing rod 30 seals the oil inlet 50, preventing air from entering the oil tank 10 and effectively improving the storage time of the standard oil sample.

[0033] In addition, the two ends of the support spring 3006 abut against the movable ring 3015 and the push plate 3007 respectively. The push plate 3007 is designed in a ring shape. By pressing down the top plate 3009, the push plate 3007 can push the movable ring 3015 downward to squeeze the support spring 3006 and give it elastic potential energy.

[0034] It should be noted that the top plate 3009 has a threaded hole 3010 on its top, and the top of the lead screw 3011 is provided with a handle 3012 to facilitate the rotation of the lead screw 3011. The sealing rod 30 has multiple fixing holes 3002 on its outside. When the movable ring 3015 does not apply pressure to the support spring 3006, the elastic potential energy of the support spring 3006 acts in the opposite direction on the movable ring 3015 and causes the movable ring 3015 to move upward. During this process, the limiting block 3005 is pulled out from the limiting groove 3014 and moves into the fixing hole 3002.

[0035] Understandably, the lead screw 3011 is threadedly connected to both the threaded hole 3010 and the threaded groove 3013. Rotating the lead screw 3011 into the threaded groove 3013 fixes the position of the movable ring 3015. The sealing gasket 3001 is made of rubber, which facilitates pressing the sealing gasket 3001 to the bottom of the oil inlet 50 to achieve a sealing effect, thereby improving the sealing performance of the standard oil sample during storage. The number of fixing holes 3002 is the same as the number of limiting blocks 3005.

[0036] It should be added that the movable ring 3015 can only move upward a limited distance. When the movable ring 3015 moves to the top, the limit block 3005 just moves completely into the fixed hole 3002.

[0037] Please see Figure 1 and Figure 6-8 The housing 40 is equipped with a controller 4002 inside and an operation panel 4003 outside. The operation panel 4003 can accurately measure the amount of oil to avoid waste. The oil tank 10 is equipped with an oil outlet pipe 4004, and a pump head 4005 is installed at one end of the oil outlet pipe 4004. The pump head 4005 is of model VP-12-FA3-DH or VP-12-FA3-D.

[0038] It should be emphasized that the bottom of the housing 40 is provided with a placement hole 4001, and the other end of the oil outlet pipe 4004 is fixed with an oil outlet head 4006. A placement groove 4007 is provided on one side of the housing 40. The oil outlet pipe 4004 is designed as a flexible hose. The placement groove 4007 is connected to the placement hole 4001. The width of the placement groove 4007 is smaller than the diameter of the oil outlet head 4006. The oil outlet head 4006 can be placed upside down into the placement hole 4001 to prevent residual oil in the oil outlet pipe 4004 from dripping onto the ground. At the same time, the housing 40 can also protect the oil outlet head 4006 from dust.

[0039] Specifically, the working principle of this sealing device that can preserve standard oil samples for a long time is as follows:

[0040] In use, a standard oil sample can be poured into the oil container 10 through the oil inlet 50 for storage. Then, the sealing rod 30 is inserted into the inside of the oil inlet 50. At this time, the sealing gasket 3001 is pressed to the bottom of the oil inlet 50, achieving a sealing effect. Next, the top plate 3009 is pressed downward, which causes the push plate 3007 to push the movable ring 3015 downward to press the support spring 3006 and give it elastic potential energy. At the same time, the hinge rod 3004 pushes the limiting block 3005 to insert into the limiting groove 3014. Then, rotate the lead screw 3011 downwards into the thread groove 3013 to complete the sealing process of the oil inlet 50. Even after long-term use of the standard oil sample, the sealing effect will not be compromised. When the standard oil sample needs to be taken, first move the oil outlet 4006 upwards, then flatten the oil outlet pipe 4004, take the oil outlet pipe 4004 out from the placement groove 4007, and input the number of milliliters of the standard oil sample to be taken through the operation panel 4003. Finally, the controller 4002 controls the pump head 4005 to take the oil.
