Description

Technical Field

[0001] This utility model relates to the field of oil and gas storage and transportation heating, and in particular to an electric heating device for oil and gas storage with protective functions. Background Technology

[0002] With social development, oil and gas resources are becoming increasingly important in the energy sector. The use of oil pipelines in the oil and gas storage and transportation process is extremely critical. In cold regions or when the viscosity of oil and gas is high, the flow of oil and gas in the pipeline will be greatly reduced, and even condensation and blockage may occur, which will seriously affect the normal transportation of oil and gas. In order to ensure that oil and gas can flow smoothly, it is necessary to heat the pipeline to reduce the viscosity of oil and gas and maintain its good transportation condition.

[0003] However, existing heating methods mostly use open flame combustion, which not only poses safety hazards such as fire and explosion, but also easily causes uneven heat distribution, leading to local overheating and damage to oil pipelines. At the same time, open flame heating is inefficient and wastes a lot of energy, failing to meet the needs of safe and efficient oil and gas storage and transportation. Utility Model Content

[0004] In view of this, the present invention provides an electric heating device for oil and gas storage with protective function. The main technical problem to be solved is to address the problems of large safety hazards, uneven heat distribution, low heating efficiency and energy waste in existing open flame heating of oil and gas storage pipelines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electric heating device for oil and gas storage with protective function, comprising a support base, a support block fixedly installed on the top of the support base, a support frame fixedly connected inside the support block, two symmetrically distributed semi-circular clamping blocks movably installed on the top of the support block, a transport pipe installed between the two semi-circular clamping blocks, a drive assembly installed between the support frame and the semi-circular clamping blocks, and a heating assembly installed between the support base and the semi-circular clamping blocks;

[0006] The support base has a water storage cavity inside;

[0007] The heating assembly includes a water pump, a water supply pipe, a first sealing cover, an input hose, a heating tube, a second sealing cover, an output hose, and a heating wire. The water pump is fixedly installed inside the water storage chamber. The water supply pipe is fixedly installed at the output end of the water pump and passes through the top of the support base. The first sealing cover is fixedly connected to the right side of the outer wall of the semi-circular clamping block. An input hose is fixedly installed between the water supply pipe and the two first sealing covers. Multiple heating tubes are movably installed on the inner wall of the semi-circular clamping block. The heating tubes communicate with the inner cavity of the first sealing cover. The second sealing cover is fixedly connected to the left side of the outer wall of the semi-circular clamping block. An output hose is fixedly connected to the outer wall of the second sealing cover. The output ends of the two output hoses are fixedly connected to the top of the support base and communicate with the support base.

[0008] Multiple heating wires are fixedly installed on the inner wall of the water storage cavity.

[0009] By adopting the above technical solution, the heat-conducting liquid in the water storage chamber is heated by an electric heating wire, and then the heat-conducting liquid is transported to the heating pipe by a water pump to heat the transport pipe, thus achieving safe and uniform heating, avoiding the safety hazards caused by open flames, and improving heating efficiency.

[0010] As a further description of the above technical solution: the inner wall of the semi-circular clamping block is provided with an installation groove, and multiple through holes are provided on the left and right sides of the installation groove. The heating tube is fixedly installed inside the installation groove, and both ends of the heating tube are connected to the through holes.

[0011] By adopting the above technical solution, the mounting groove provides a fixed installation position for the heating tube, and the through hole enables the heat transfer fluid to flow between the heating tube and the sealing cover, so that the heating tube can better heat the transport tube from all directions.

[0012] As a further description of the above technical solution: the top of the support block is fixedly connected to a support shaft, and the bottom of each of the two semi-circular clamping blocks is fixedly connected to multiple ear plates. The two sets of ear plates are staggered and movably installed on the outer wall of the support shaft.

[0013] By adopting the above technical solution, the cooperation between the support shaft and the ear plate provides rotational support for the semi-circular clamping block, enabling the semi-circular clamping block to rotate flexibly around the support shaft, which facilitates the clamping and releasing operation of the transport tube.

[0014] As a further description of the above technical solution: the drive assembly includes a bidirectional lead screw, a moving block, a connecting rod, and a roller. The bidirectional lead screw is movably installed inside the support frame, and two moving blocks are slidably installed inside the support frame. The moving blocks have screw holes corresponding to the bidirectional lead screw inside. The connecting rod is fixedly connected to the outer wall of the semi-circular clamping block. A roller is movably installed at the end of the connecting rod away from the semi-circular clamping block. A lifting groove is opened inside the moving block, and the roller is movably installed inside the lifting groove.

[0015] By adopting the above technical solution, when the bidirectional lead screw rotates, it can drive two moving blocks to move synchronously. Then, through the connecting rod and roller, the linear motion of the moving blocks is converted into the circular motion of the semi-circular clamping block, thereby realizing the clamping or releasing action of the semi-circular clamping block on the transport pipe.

[0016] As a further description of the above technical solution: the drive assembly also includes a first spring, an upper push plate, a second spring, and a lower push plate. The bottom of the inner wall of the lifting groove is fixedly connected to the first spring, the top of the first spring is fixedly installed with the upper push plate, the top of the inner wall of the lifting groove is fixedly installed with the second spring, the bottom of the second spring is fixedly installed with the lower push plate, and the roller is located between the upper push plate and the lower push plate.

[0017] By adopting the above technical solution, spring one and spring two, together with the upper push plate and the lower push plate, provide elastic support for the roller, play a buffering and resetting role during the opening and closing of the semi-circular clamping block, and ensure that the semi-circular clamping block can stably clamp the transport pipe.

[0018] As a further description of the above technical solution: both ends of the bidirectional lead screw penetrate the outer wall of the support frame, and both ends of the bidirectional lead screw are provided with cross grooves.

[0019] By adopting the above technical solution, the cross-shaped groove facilitates the use of a Phillips screwdriver to rotate the bidirectional lead screw, thereby enabling the operation of the drive component.

[0020] As a further description of the above technical solution: the outer wall of the support base is fixedly connected with a water injection hole, the water injection hole is connected to the water storage cavity, and a plug is fixedly installed inside the water injection hole.

[0021] By adopting the above technical solution, the water injection hole facilitates the addition of heat-conducting fluid into the water storage cavity, and the plug can prevent the heat-conducting fluid from leaking.

[0022] By employing the above technical solution, the electric heating device for oil and gas storage with protective function of this utility model has at least the following beneficial effects:

[0023] 1. Compared with existing technologies, this protective oil and gas storage electric heating device uses heating components to heat the heat transfer fluid in the storage chamber with heating wires. A water pump pumps the heat transfer fluid to the heating pipe, which surrounds the transport pipe to heat it. The heated heat transfer fluid then flows back to the storage chamber for recycling. This avoids contact with open flames and eliminates safety hazards such as fire and explosion. At the same time, the circulation of the heat transfer fluid ensures that the transport pipe is heated evenly, protecting it from damage caused by localized overheating. It also improves energy utilization efficiency and reduces energy consumption.

[0024] 2. Compared with the existing technology, this protective oil and gas storage electric heating device, through the setting of a drive component, the bidirectional screw rotates to drive the moving block to move. The moving block, through the cooperation of spring and roller, makes the semi-circular clamping block rotate around the support shaft, realizing the clamping and loosening of the transport pipe. It can quickly and stably fix the two semi-circular clamping blocks to the outer wall of the transport pipe, which facilitates the installation and disassembly of the device and improves work efficiency.

[0034] Reference Figure 1-7 This utility model provides an electric heating device for oil and gas storage with protective function, comprising: a support base 1, a support block 2 fixedly installed on the top of the support base 1, a support frame 3 fixedly connected inside the support block 2, the support frame 3 being fixedly connected to the support block 2, two symmetrically distributed semi-circular clamping blocks 4 movably installed on the top of the support block 2, the two semi-circular clamping blocks 4 being symmetrically installed and movable, facilitating the clamping and releasing operation of the transport pipe 5, the transport pipe 5 being installed between the two semi-circular clamping blocks 4, the transport pipe 5 being used to transport oil and gas, the semi-circular clamping blocks 4 being able to fix and heat it, a drive assembly 6 being installed between the support frame 3 and the semi-circular clamping blocks 4, the drive assembly 6 being used to drive the opening and closing action of the semi-circular clamping blocks 4, realizing the clamping and releasing of the transport pipe 5, and a heating assembly 7 being installed between the support base 1 and the semi-circular clamping blocks 4, the heating assembly 7 providing a heating function for the transport pipe 5, ensuring that the oil and gas maintain good fluidity during transportation.

[0035] The support base 1 has a water storage chamber 101 inside. The water storage chamber 101 is used to store heat transfer fluid and is an important component of the heating assembly 7 to achieve circulating heating, providing a medium for the subsequent heating process.

[0036] Heating assembly 7 includes a water pump 701, a water supply pipe 702, a first sealing cover 703, an input hose 704, a heating element 705, a second sealing cover 706, an output hose 707, and a heating wire 709. The water pump 701 is fixedly installed inside the water storage chamber 101. The function of the water pump 701 is to extract the heat transfer fluid from the water storage chamber 101 and transport it to subsequent pipes, providing power for the circulation of the heat transfer fluid. The output end of the water pump 701 is fixedly installed with the water supply pipe 702, which connects the water pump 701 and the input hose 704, serving as a channel for transmitting the heat transfer fluid, allowing the heat transfer fluid to flow smoothly from the water pump 701. The water storage chamber 101 delivers water to the heating pipe 705 on the semi-circular clamping block 4. The water supply pipe 702 passes through the top of the support base 1. This through-through design ensures the connection between the water supply pipe 702 and the water storage chamber 101 inside the support base 1 and the external semi-circular clamping block 4, realizing the transmission path of the heat transfer fluid. A sealing cover 703 is fixedly connected to the right side of the outer wall of the semi-circular clamping block 4. The sealing cover 703 is used to connect the input hose 704 and the heating pipe 705, playing a role in sealing and guiding the flow, preventing the heat transfer fluid from leaking, and at the same time smoothly introducing the heat transfer fluid into the heating pipe 705. The water supply pipe 702 and the two sealing covers 703 An input hose 704 is fixedly installed between the two. The input hose 704 has a certain degree of flexibility, which can accommodate the opening and closing of the semi-circular clamping block 4 while ensuring the delivery of heat transfer fluid, thus ensuring the stability of the connection. Multiple heating tubes 705 are movably installed on the inner wall of the semi-circular clamping block 4. The multiple heating tubes 705 surround the outer wall of the transport pipe 5, which can provide all-round and uniform heating to the transport pipe 5, ensuring the heating effect of oil and gas. The heating tubes 705 are connected to the inner cavity of the sealing cover 703, so that the heat transfer fluid in the sealing cover 703 can flow smoothly into the heating tubes 705 to realize the heating function. The semi-circular clamping block 4... A sealing cover 706 is fixedly connected to the left side of the outer wall. The sealing cover 706 is connected to the heating tube 705 and the output hose 707. It is used to collect the heated heat transfer fluid in the heating tube 705 and transport it to the output hose 707. The outer wall of the sealing cover 706 is fixedly connected to the output hose 707. The output hose 707 transports the heat transfer fluid in the sealing cover 706 back to the water storage chamber 101 of the support base 1, forming a circulation loop for the heat transfer fluid. The output ends of the two output hoses 707 are fixedly connected to the top of the support base 1 and communicate with the support base 1 to ensure that the heat transfer fluid can flow back to the water storage chamber 101 smoothly.

[0037] Multiple heating wires 709 are fixedly installed on the inner wall of the water storage cavity 101. The multiple heating wires 709 are distributed on the inner wall of the water storage cavity 101, which can evenly heat the heat-conducting liquid in the water storage cavity 101 and provide a heat source for the entire heating process.

[0038] The inner wall of the semicircular clamping block 4 is provided with an installation groove 401, which provides installation space for the heating tube 705, allowing the heating tube 705 to be stably installed on the inner wall of the semicircular clamping block 4, ensuring the relative position between the heating tube 705 and the transport tube 5, thereby achieving a stable heating effect. Multiple through holes 402 are provided on the left and right sides of the installation groove 401. The through holes 402 serve as channels for the heat transfer fluid to enter and exit the heating tube 705, allowing the heat transfer fluid to flow between the first sealing cover 703, the heating tube 705, and the second sealing cover 706, thereby heating the transport tube 5. The heating tube 705 is fixedly installed inside the installation groove 401, ensuring the fixed position of the heating tube 705 on the semicircular clamping block 4, and ensuring the stability and reliability of the heating process. Both ends of the heating tube 705 are connected to the through holes 402, enabling the heat transfer fluid to flow within the heating tube 705, allowing the heating tube 705 to effectively transfer heat to the transport tube 5.

[0039] A support shaft 201 is fixedly connected to the top of the support block 2. The support shaft 201 provides a support point for the rotation of the semi-circular clamping block 4, ensuring that the semi-circular clamping block 4 can rotate flexibly around it. Multiple ear plates 403 are fixedly connected to the bottom of both semi-circular clamping blocks 4. The ear plates 403 are used to connect with the support shaft 201. Through the cooperation between the ear plates 403 and the support shaft 201, the semi-circular clamping block 4 can be movably installed on the top of the support block 2. The two sets of ear plates 403 are staggered and movably installed on the outer wall of the support shaft 201. The staggered design ensures that the two semi-circular clamping blocks 4 do not interfere with each other during rotation, ensuring the smoothness of the opening and closing action of the semi-circular clamping blocks 4.

[0040] Drive assembly 6 includes a bidirectional lead screw 601, a moving block 602, a connecting rod 603, and a roller 604. The bidirectional lead screw 601 is movably mounted inside the support frame 3 and can rotate within the support frame 3. Its rotation drives the moving block 602 to move. Two moving blocks 602 are slidably mounted inside the support frame 3 and can slide along a certain direction within the support frame 3. These two moving blocks 602 cooperate with the bidirectional lead screw 601 to convert the rotation of the bidirectional lead screw 601 into linear motion. The moving blocks 602 have threaded holes corresponding to the threads of the bidirectional lead screw 601, allowing the moving blocks 602 to move left and right when the bidirectional lead screw 601 rotates. A connecting rod 603 is fixedly connected to the outer wall of the circular clamping block 4. The connecting rod 603 is used to connect the semi-circular clamping block 4 and the roller 604, and transmits the linear motion of the moving block 602 to the semi-circular clamping block 4 to realize the rotation of the semi-circular clamping block 4. The roller 604 is movably installed at the end of the connecting rod 603 away from the semi-circular clamping block 4. The roller 604 can roll and rise and fall in the lifting groove of the moving block 602. With the help of spring 1 605 and spring 2 607, the semi-circular clamping block 4 can be opened and closed smoothly. The moving block 602 has a lifting groove inside, which provides the roller 604 with a space for movement, so that the roller 604 can rise and fall when the moving block 602 moves, thereby driving the semi-circular clamping block 4 to rotate around the support shaft 201.

[0041] The drive assembly 6 also includes a first spring 605, an upper push plate 606, a second spring 607, and a lower push plate 608. The first spring 605 is fixedly connected to the bottom of the inner wall of the lifting groove. The first spring 605 is compressed when the semi-circular clamping block 4 releases the transport pipe 5, and provides an upward thrust when clamping the transport pipe 5, assisting the semi-circular clamping block 4 in clamping the transport pipe 5. The upper push plate 606 is fixedly installed on the top of the first spring 605. The upper push plate 606 contacts the roller 604, transmitting the elastic force of the first spring 605 to the roller 604, pushing the semi-circular clamping block 4 to rotate upwards. The second spring 607 is fixedly installed on the top of the inner wall of the lifting groove. When the semicircular clamping block 4 clamps the transport tube 5, it is in a compressed state. When the transport tube 5 is released, it provides a downward pushing force to assist the semicircular clamping block 4 in releasing the transport tube 5. The bottom of the second spring 607 is fixedly installed with a push plate 608. The push plate 608 contacts the roller 604 and transmits the elastic force of the second spring 607 to the roller 604, pushing the semicircular clamping block 4 to rotate downward. The roller 604 is located between the upper push plate 606 and the lower push plate 608. Under the action of the first spring 605 and the second spring 607, the roller 604 moves up and down in the lifting groove, driving the semicircular clamping block 4 to rotate around the support shaft 201, thereby realizing the clamping and releasing of the transport tube 5.

[0042] Both ends of the bidirectional lead screw 601 penetrate the outer wall of the support frame 3, making it easy to rotate the bidirectional lead screw 601 using tools to control the drive component 6. Both ends of the bidirectional lead screw 601 are provided with cross grooves 609, which can be used with corresponding Phillips screwdrivers to facilitate the operator to rotate the bidirectional lead screw 601 and control the opening and closing of the semi-circular clamping block 4.

[0043] A water injection hole 708 is fixedly connected to the outer wall of the support base 1. The water injection hole 708 provides a channel for adding heat transfer fluid to the water storage chamber 101, which facilitates the replenishment and replacement of heat transfer fluid during the use of the equipment. The water injection hole 708 is connected to the water storage chamber 101 to ensure that the heat transfer fluid can flow smoothly into the water storage chamber 101. A plug is fixedly installed inside the water injection hole 708 to prevent the heat transfer fluid in the water storage chamber 101 from leaking, thus ensuring the normal operation of the heating component 7 and the safety of the equipment.

[0044] Working principle: When in use, first insert a Phillips screwdriver into the Phillips grooves 609 at both ends of the double-acting screw 601, and rotate the double-acting screw 601 clockwise. Since the threads at both ends of the double-acting screw 601 turn in opposite directions, during the rotation, the two moving blocks 602 that are threaded with the double-acting screw 601 will slide in opposite directions within the support frame 3, that is, move outwards simultaneously. At this time, the semi-circular clamping block 4 is movably installed in the lifting groove of the moving block 602 through the connecting rod 603 and the roller 604. As the moving block 602 moves outwards, the second spring 607 is in the extended state, and its downward thrust pushes the roller 604 to move downwards. At the same time, in conjunction with the outward movement of the moving block 602, the two semi-circular clamping blocks 4 make a circular motion around the support shaft 201, thereby realizing the opening of the two semi-circular clamping blocks 4. At this time, the second spring 607 is in the fully released state, and the first spring 605 is compressed.

[0045] Next, the transport tube 5 is placed between the two opened semi-circular clamping blocks 4. Then, the bidirectional lead screw 601 is rotated counterclockwise, causing the moving block 602 to move inward. At this time, the compressed spring 605 generates an upward thrust, pushing the roller 604 to move upward, causing the two semi-circular clamping blocks 4 to rotate in the opposite direction around the support shaft 201, so that the semi-circular clamping blocks 4 are merged, thereby firmly clamping the transport tube 5. At the same time, the second spring 607 is compressed.

[0046] After the transport pipe 5 is installed and fixed, the power is turned on, and multiple heating wires 709 on the inner wall of the water storage chamber 101 start to work, uniformly heating the heat transfer fluid in the water storage chamber 101. When the heat transfer fluid reaches a suitable temperature, the water pump 701 is started. The water pump 701 draws out the heated heat transfer fluid and delivers it to the input hose 704 through the water delivery pipe 702. The input hose 704, with its flexibility, ensures the delivery of the heat transfer fluid while adapting to the installation state of the semi-circular clamping block 4, and stably delivers the heat transfer fluid to the sealing cover 703 on the right side of the outer wall of the semi-circular clamping block 4. The sealing cover 703 plays a sealing and guiding role, allowing the heat transfer fluid to flow smoothly into multiple heating pipes 705 through the through holes 402 on both sides of the mounting groove 401 on the inner wall of the semi-circular clamping block 4. The multiple heating pipes 705 surrounding the outer wall of the transport pipe 5 transfer the heat of the heat transfer fluid to the transport pipe 5, heating the oil and gas in the pipe in an all-round and uniform manner to maintain good oil and gas flow.

[0047] After heat transfer is completed, the heat transfer fluid flows through the through hole 402 at the other end of the heating pipe 705 into the sealing cover 706 on the left side of the outer wall of the semi-circular clamping block 4, and then flows back to the water storage cavity 101 of the support base 1 through the output hose 707, forming a circulating heating circuit for the heat transfer fluid, and continuously providing a stable heating effect for the transport pipe 5.
