Description

Technical Field

[0001] The present invention relates to the technical field of temperature detection, and particularly to a temperature transmitter for oil fields with an efficient heat dissipation function. Background Art

[0002] When crude oil is transported in a pipeline, the crude oil needs to be maintained at a temperature above 50 degrees Celsius to avoid a large amount of paraffin precipitation in the crude oil. Operators install a detection pipeline and a temperature transmitter to monitor the temperature of the crude oil in the transportation pipeline.

[0003] The existing heat dissipation method of the temperature transmitter is single. Affected by the high temperature of the crude oil, the internal temperature of the temperature transmitter rises rapidly, resulting in damage to the components inside the temperature transmitter. At the same time, a small amount of paraffin precipitated due to temperature changes in the crude oil, as well as impurities such as gum, coagulated oil, and sand in the crude oil, will adhere to the outer surface of the temperature transmitter, affecting the heat transfer to the temperature sensor, making the temperature measurement of the crude oil in the detection pipeline by this device inaccurate, resulting in the inability of the operator to make timely adjustments. At the same time, the part of this device extending into the detection pipeline is affected by the pressure change of the crude oil in the detection pipeline, causing the device to shake and resulting in damage to this device, making it impossible to detect the temperature of the crude oil in the detection pipeline.

[0004] Therefore, we provide a temperature transmitter for oil fields with an efficient heat dissipation function, which has a hybrid heat dissipation method, a self-cleaning function, and can avoid equipment shaking. Summary of the Invention

The lower end of the rotating sleeve 406 is fixedly connected to the third bevel gear 5. The first fixing column 501 is fixedly connected inside the lower part of the first protective shell 105. The fourth bevel gear 502 is rotatably arranged at the rear of the first fixing column 501. The fourth bevel gear 502 meshes with the third bevel gear 5. The rotating ring 503 is rotatably arranged at the lower end of the first protective shell 105. The upper end of the rotating ring 503 is fixedly connected to the fifth bevel gear 504. The fifth bevel gear 504 meshes with the fourth bevel gear 502. The lower part of the rotating ring 503 is provided with the second protective shell 505. The rotating ring 503 rotates on the second protective shell 505. The outer surface of the second protective shell 505 is smooth. The upper and lower ends of the rotating ring 503 are fixedly connected with the first rubber ring 506. The lower end of the first fixing column 501 is fixedly connected with two second fixing columns 507. The third fixing column 508 is fixedly connected inside the upper part of the second protective shell 505. The third fixing column 508 is fixedly connected to the lower ends of the two second fixing columns 507. The first fixing column 501, the two second fixing columns 507 and the third fixing column 508 form a fixing frame for fixing the first protective shell 105 and the second protective shell 505, so that the rotating ring 503 rotates smoothly between the first protective shell 105 and the second protective shell 505. Four scrapers 509 are evenly fixedly connected to the side wall of the rotating ring 503. The lower ends of the four scrapers 509 are fixedly connected with the fixing ring 510. The fixing ring 510 is sleeved on the second protective shell 505 and is rotatably arranged therewith. The scrapers 509 rotate to clean the surface of the second protective shell 505, improving the measurement accuracy of the temperature sensor 107 for the temperature of the crude oil in the detection pipeline 1.

[0040] As Figure 11 and Figure 12As shown in the figure, the fixing mechanism includes a sliding housing 6, a second fixing block 601, a spring 602, a second rubber ring 603, a third rubber ring 604 and a first sealing ring 607. A sliding housing 6 is slidably arranged at the lower part of the second protective housing 505. A plurality of small grooves are formed on the lower surface of the sliding housing 6 to increase the friction between the sliding housing 6 and the detection pipeline 1. A second fixing block 601 is fixedly connected inside the lower part of the second protective housing 505. A spring 602 is fixedly connected between the second fixing block 601 and the sliding housing 6. A second rubber ring 603 is fixedly connected to the lower end of the sliding housing 6. A third rubber ring 604 is fixedly connected to the upper end of the sliding housing 6. The first rubber ring 506, the second rubber ring 603 and the third rubber ring 604 are all made of nitrile rubber, and the upper surfaces of the first rubber ring 506, the second rubber ring 603 and the third rubber ring 604 are all arranged as inclined surfaces facing the lower side outward, so as to make the first rubber ring 506, the second rubber ring 603 and the third rubber ring 604 be in close contact with adjacent parts respectively. A first annular groove 605 is formed on the inner side wall of the upper part of the sliding housing 6. A plurality of through holes 606 are formed on the upper part of the sliding housing 6. The inner ends of the through holes 606 communicate with the first annular groove 605. A first sealing ring 607 is arranged in the first annular groove 605. The crude oil enters the first annular groove 605 through the through holes 606 and extrudes the first sealing ring 607, so that the first sealing ring 607 is in closer contact with the second protective housing 505, increasing the sealing performance between the first sealing ring 607 and the second protective housing 505. The first sealing ring 607 is made of silicone rubber to extend the service life of the first sealing ring 607.

[0041] The power cord connected to the wire outlet 108 supplies power to the electric rotating shaft 201, causing the electric rotating shaft 201 to rotate clockwise. The clockwise rotation of the electric rotating shaft 201 drives the exhaust fan 202 to rotate clockwise, enabling cold air to enter the housing 101 through the first conical hole 203. Subsequently, the cold air mixes with the hot air inside the housing 101 and is discharged from the special-shaped hole 204, completing the heat dissipation of the temperature transmitter module 103. The first conical hole 203 is inclined at the lower part of the housing 101 and the special-shaped hole 204, so that in rainy weather, rainwater is prevented from directly entering the device and damaging the temperature transmitter module 103. At the same time, the upper-small-lower-large setting of the first conical hole 203 reduces the entry of water vapor in the air into the device and damages the temperature transmitter module 103. The bent setting of the special-shaped hole 204 enables the condensed water droplets on the surface of the special-shaped hole 204 when water vapor in the air condenses to fall on the lower surface of the special-shaped hole 204 and be discharged from the device through the vertical hole 205, preventing the condensed water droplets from dripping into the device.

[0042] While the electric rotating shaft 201 rotates clockwise, it drives the first straight gear 301 to rotate clockwise. The clockwise rotation of the first straight gear 301 drives the sliding rod 303 to move up and down reciprocally through the rotating rod 302. When the sliding rod 303 moves downward and drives the L-shaped rod 304 and the parts thereon to move downward, under the action of the coolant in the liquid storage tank 3, the conical sealing block 308 will move upward, so that the conical sealing block 308 contacts and seals the hole of the push plate 305. Subsequently, the L-shaped rod 304 continues to move downward to push the coolant in the liquid storage tank 3, so that the coolant flows through the cooling pipe 309. Through the winding arrangement of the cooling pipe 309, and since the cooling pipe 309 is made of brass, it speeds up the heat absorption and cooling of the temperature transmitter module 103 by the coolant. Subsequently, the coolant flows back to the liquid storage tank 3 through the heat dissipation pipe 310. Because the heat dissipation pipe 310 is made of brass, and the middle part of the heat dissipation pipe 310 is provided with multiple pipes connected, and a number of brass sheets are provided on the outer side wall, it enables the coolant to dissipate heat quickly when flowing in the heat dissipation pipe 310.

[0043] When the sliding rod 303 moves upward and drives the L-shaped rod 304 and the parts thereon to move upward, under the action of the coolant in the liquid storage tank 3, the conical sealing block 308 will move downward, so that the conical sealing block 308 is separated from the hole of the push plate 305. As the L-shaped rod 304 moves upward, the coolant in the liquid storage tank 3 will flow downward through the hole of the push plate 305, and then continue to work reciprocally according to the above operations, so that the coolant in the liquid storage tank 3 circulates and rotates to complete the continuous cooling of the temperature transmitter module 103.

[0044] The part of this device placed in the detection pipeline 1 contacts the crude oil therein. The temperature of the crude oil is transmitted upward through the first protective shell 105. When the temperature of the crude oil in the detection pipeline 1 is transmitted upward, it is absorbed by the first heat dissipation block 409, preventing the temperature of the crude oil from being transmitted to the inside of the outer shell 101 through the first protective shell 105 and causing damage to the temperature transmitter module 103 due to high temperature. The heat absorbed by the first heat dissipation block 409 is transmitted to the second heat dissipation block 410 to dissipate the transmitted temperature. While the first straight gear 301 rotates clockwise, it will drive the second straight gear 403 to rotate counterclockwise. The second straight gear drives the first bevel gear 404 to rotate counterclockwise through the rotating shaft 402. The counterclockwise rotation of the first bevel gear 404 drives the second bevel gear 407 to rotate clockwise. The second bevel gear 407 drives the cooling fan 408 to rotate clockwise through the rotating sleeve 406, so that the cooling fan 408 blows on the second heat dissipation block 410. The outside cold air enters the first protective shell 105 through the arc-shaped hole 411 and mixes with the hot air, and then the mixed air is discharged through the second conical hole 412 and the horizontal hole 413. At this time, the mixed air also takes away part of the heat on the second heat dissipation block 410, increasing the heat dissipation effect of the second heat dissipation block 410 and preventing the temperature of the crude oil from being transmitted to the inside of the outer shell 101 through the first protective shell 105.

[0045] While the rotating sleeve 406 rotates clockwise, it will drive the third bevel gear 5 to rotate clockwise. The third bevel gear 5 drives the fifth bevel gear 504 to rotate counterclockwise through the fourth bevel gear 502. The fifth bevel gear 504 drives the rotating ring 503, the first rubber ring 506, the scraper 509 and the fixing ring 510 to rotate counterclockwise. Among them, the counterclockwise rotation of the scraper 509 scrapes the outer surface of the second protective shell 505 to prevent impurities such as paraffin, gum, congealed oil, and sand in the crude oil from adhering to the outer surface of the second protective shell 505, which affects the measurement of the crude oil temperature by the temperature sensor 107. When disassembling this equipment, first disconnect the power cord connected to the wire bundling port 108, then close the valve at the left end of the detection pipeline 1, and finally loosen and remove this equipment from the detection pipeline 1.

[0046] When installing this equipment, as the operator inserts this equipment into the detection pipeline 1, the bottom surface of the sliding shell 6 will contact the inner wall of the detection pipeline 1. Then the operator continues to press this equipment. At this time, the sliding shell 6 and the parts on it will remain stationary, and the second protective shell 505 will continue to move downward to compress the spring 602. Subsequently, the operator fixes this equipment. After fixing, open the valve to fill the detection pipeline 1 with crude oil. At this time, under the pressure of the crude oil, the crude oil will squeeze the first sealing ring 607 through the through hole 606, increasing the sealing performance between the first sealing ring 607 and the second protective shell 505. The first sealing ring 607 is made of silicone rubber, and silicone rubber is heat-resistant, so that the first sealing ring 607 still maintains a good sealing effect under the action of high-temperature crude oil in the detection pipeline 1. At the same time, the crude oil squeezes the second rubber ring 603 and the third rubber ring 604. The second rubber ring 603 is squeezed by the crude oil, which will make the sliding shell 6 in close contact with the inner wall of the detection pipeline 1, preventing this equipment from being impacted by the pressure fluctuation of the crude oil in the detection pipeline 1 and causing this equipment to shake, which affects the sealing performance of this equipment. The third rubber ring 604 is under the action of the crude oil pressure, making the third rubber ring 604 contact the second protective shell 505 more tightly.

[0047] Embodiment 3

[0048] On the basis of Embodiment 2, as Figure 2 and Figure 13As shown in the figure, a sealing mechanism is further included. The sealing mechanism is provided at the lower part of the fixed disk 106, and includes a frustum-shaped positioning block 7, a fixed slider 702, a sliding ring 703, a second sealing ring 708 and a conveying pipe 709. The lower surface of the fixed disk 106 is fixedly connected with the frustum-shaped positioning block 7. An irregular-shaped sliding groove 701 is formed in the frustum-shaped positioning block 7. The left and right parts of the sliding groove are respectively provided with fixed sliders 702. The two fixed sliders 702 are symmetrically arranged. The outer end faces of the two fixed sliders 702 are rough to increase the friction between the fixed slider 702 and the detection pipeline 1. The lower part of the sliding groove is provided with a sliding ring 703. The lower surface of the fixed disk 106 is provided with a second annular groove 705 and a third annular groove 707. The third annular groove 707 is located on the outer ring of the second annular groove 705. Several first diversion holes 704 are formed in the upper part of the frustum-shaped positioning block 7. The first diversion holes 704 communicate the irregular-shaped sliding groove 701 and the second annular groove 705. Several second diversion holes 706 are formed in the fixed disk 106. The second diversion holes 706 communicate the second annular groove 705 and the third annular groove 707. A second sealing ring 708 is installed in the third annular groove 707. The lower surface of the second sealing ring 708 is arc-shaped. The upper surface of the fixed disk 106 is fixedly connected with two symmetrically arranged conveying pipes 709. The lower ends of the two conveying pipes 709 are both communicated with the second annular groove 705. A valve is provided on each conveying pipe 709. The sealing mechanism is used to improve the sealing performance between the fixed disk 106 and the detection pipeline 1 and firmly fix the device on the detection pipeline 1.

[0049] When bolt-fixing this device, the operator inserts this device into the detection pipeline 1. Under the action of the lower surface of the frustum positioning block 7, this device is vertically inserted into the detection pipeline 1. Subsequently, the operator presses down the fixing plate 106 and fixes the fixing plate 106 and the detection pipeline 1 with bolts. After the fixing is completed, the operator opens the valves on the two conveying pipes 709 and connects a hose to the upper end of the left conveying pipe 709. A water pump is provided at the end of the hose. The operator turns on the water pump to inject hydraulic oil into the second annular groove 705. After injecting a part, the water pump is turned off and left standing for a period of time. The hydraulic oil in the second annular groove 705 flows into the special-shaped sliding groove 701 through the first diversion hole 704. Subsequently, hydraulic oil is intermittently injected into the fixing plate 106. As the hydraulic oil is injected, the hydraulic oil in the second annular groove 705 will flow into the third annular groove 707 through the second diversion hole 706. Finally, the hydraulic oil flows out from the right conveying pipe 709. Then the operator turns off the water pump and the valves on the conveying pipe 709. When the detection pipeline 1 is filled with crude oil, under the action of the pressure of the crude oil, the crude oil will push the sliding ring 703 upward. The sliding ring 703 moves upward to compress the hydraulic oil in the special-shaped sliding groove 701, causing the fixed slider 702 to move outward, increasing the friction between the fixed slider 702 and the detection pipeline 1, making this device fixed more firmly. At the same time, the pressure in the special-shaped sliding groove 701 increases and will, through the first diversion hole 704, the second annular groove 705 and the second diversion hole 706, cause the pressure in the third annular groove 707 to increase, causing the hydraulic oil to squeeze the second sealing ring 708 downward. The second sealing ring 708 is deformed by the extrusion, increasing the contact area between the second sealing ring 708 and the detection pipeline 1, improving the sealing effect between this device and the detection pipeline 1. When disassembling this device, first close the valve on the right part of the detection pipeline 1. Then the operator connects the upper ends of the two conveying pipes 709 with a hose and opens the valves on the two conveying pipes 709. Under the action of the pressure of the crude oil in the detection pipeline 1, the sliding ring 703 moves upward to press out the hydraulic oil in the frustum positioning block 7 and the fixing plate 106, causing the fixed slider 702 to release the extrusion of the detection pipeline 1. Subsequently, the operator loosens the bolts between the fixing plate 106 and the detection pipeline 1 and removes this device. Then the operator turns this device upside down to let all the hydraulic oil in the fixing plate 106 and the frustum positioning block 7 flow out, and then closes the valves on the two conveying pipes 709.
