Description

Technical Field

[0001] The present invention relates to the technical field of dynamometers, and particularly to a low-temperature operation device for a dynamometer using wind and solar energy in oil fields. Background Art

[0002] In oil field exploitation operations, a dynamometer mainly consists of multiple highly sensitive sensors and a wireless transmission module, such as sensors for load, torque, temperature, etc. Such sensors and the wireless transmission module have relatively high requirements for temperature. Excessive / high or low ambient temperature will affect the detection accuracy of the sensors and the information transmission efficiency. Most dynamometers are installed in outdoor environments, and there will also be temperature changes during the process of converting light energy into electrical energy and wind energy (mechanical energy) into internal energy (electrical energy);

[0003] It should also be noted that: the temperature difference between day and night in the oil field exploitation environment is relatively large. Both low-temperature environments and high-temperature environments will directly affect the operation process of the internal sensing structure of the dynamometer. For example, in low-temperature environments, problems such as increased signal attenuation, decreased reliability of communication protocols, and deviation of sensor measurement accuracy will occur. In high-temperature environments, problems such as increased signal attenuation, shortened transmission distance, and decreased stability will also occur, resulting in deviations in the detected data. For this, the present application proposes a solution. Summary of the Invention

[0005] The purpose of the present invention can be achieved through the following technical solutions: A low-temperature operation device for a dynamometer using wind and solar energy in oil fields, including a body and a sensing unit arranged inside the body. A combined wind and water temperature control component corresponding to the sensing unit is arranged inside the body. The combined wind and water temperature control component includes a water storage cover, a heat collection block, and a cooling fan;

[0006] The heat collection block is located in the middle section of the water storage cover. The inside of the water storage cover is divided into a heat exchange water storage tank by the heat collection block. A directional partition block is slidably installed along the length direction of the water storage cover in the heat exchange water storage tank. An enclosing arc tube corresponding to the sensing unit is installed at the external position of the water storage cover. Both ends of the enclosing arc tube are communicated with the inside of the heat exchange water storage tank. Vertical air ducts are installed on the upper and lower sides of the heat collection block. One of the air ducts is installed in the action position of the cooling fan.

[0007] Further set as: an external motion structure corresponding to the water storage cover is installed at the external position of the machine body, and the output shaft of the external motion structure penetrates through the machine body, the water storage cover and is fixedly connected to the central point position on one side of the directional partition block.

[0008] Further set as: the internal of the heat exchange water storage bin is subdivided into a first-order temperature bin and a second-order temperature bin by the directional partition block. The installation position of the first-order temperature bin is close to the installation position of the heat collection block, and both ends of the surrounding arc tube respectively correspond to the first-order temperature bin and the second-order temperature bin.

[0009] Further set as: a heating module is installed at the central point position of the outer wall on one side of the directional partition block corresponding to the first-order temperature bin.

[0010] Further set as: limited-direction cones are symmetrically arranged along the width direction of the water storage cover on the directional partition block, and a convection channel corresponding to the limited-direction cones is opened inside the directional partition block, and a connecting spring is arranged in the convection channel.

[0011] Further set as: one end position of the limited-direction cone is set as a frustum structure, and the setting direction of the frustum structure in the limited-direction cone is arranged in a staggered manner along the width direction of the water storage cover.

[0013] Further set as: the guide fins are wavy in the vertical direction, and the distances between the guide fins are equal.

[0014] The present invention has the following beneficial effects:

[0015] 1. Taking the use environment of the dynamometer in oilfield exploitation as an example, first, during the day in the operation process of wind and light energy, because the application environment temperature of the dynamometer is relatively high, the water-air combined temperature control component specifically conducts the heat dissipation process. And in the low-temperature environment at night, the application environment temperature of the dynamometer is relatively low, and for this, the water-air combined temperature control component conducts the heating process. Both the heat dissipation process and the heating process are based on the water medium in the water storage cover. For example: taking away the high heat inside the machine body through the heat exchange method, or transferring the heat in the water medium to the inside of the machine body. The overall structure specifically improves the setting method of the surrounding arc tube in the water-air combined temperature control component based on the dynamometer structure, so that the surrounding arc tube is always located outside each sensing unit for sufficient heat exchange;

[0016] 2. Supplementary description is made for the water storage cover. Specifically, based on the directional partition block, its interior is first divided into a first-order temperature chamber and a second-order temperature chamber by the directional partition block. The mixed flow process of the water-medium medium inside the water storage cover is realized through the directional sliding process of the directional partition block. During this process, the flow mode of the water-medium medium in the surrounding arc tube will also be changed. Specifically, a mixed heat process is formed in a mixed flow mode, so as to change the heat exchange process in cooperation with the air duct, the heat collection block and the heating module. Its main purpose is to maintain the stability of the temperature environment during the operation of each sensing unit, thereby reducing the degree of operation deviation in the sensing unit.

Specific implementation mode

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0026] Embodiment 1: For the application environment of the dynamometer used in oilfield exploitation operations, on the one hand, it is affected by the external environmental temperature, and on the other hand, it will also be directly affected by the temperature change in the energy supply structure (wind and solar energy), which directly affects the operation process of the sensing structure inside the dynamometer, resulting in obvious deviations in the detection data. For this reason, the present invention proposes the following technical solutions:

[0027] Refer to Figures 1 to 6 , a wind-solar energy low-temperature operation device for a dynamometer used in oilfields in this embodiment, includes a body 1 and a sensing unit arranged inside the body 1. A water-air combined temperature control component corresponding to the sensing unit is arranged inside the body 1. The water-air combined temperature control component includes a water storage cover 6, a heat collecting block 7 and a cooling fan 3;

[0028] The heat collecting block 7 is located in the middle section of the water storage cover 6. The inside of the water storage cover 6 is divided into a heat exchange water storage tank by the heat collecting block 7. A directional partition block 10 is slidably installed along the length direction of the water storage cover 6 in the heat exchange water storage tank. A surrounding arc tube 5 corresponding to the sensing unit is installed at the external position of the water storage cover 6. Both ends of the surrounding arc tube 5 are communicated with the inside of the heat exchange water storage tank. Vertical air ducts 4 are installed on the upper and lower sides of the heat collecting block 7. One of the air ducts 4 is installed in the action position of the cooling fan 3.

[0029] Basic principle: A brief description of the dynamometer used in oilfield exploitation operations is as follows: Its essence is based on multiple sensing units inside the body 1. After the overall dynamometer is installed in the corresponding mining equipment, the sensing units are used to obtain the working parameters of various equipment in real time. This part will not be elaborated here;

[0030] It should be noted that: Since most oilfield exploitation environments are in high-temperature environments such as deserts, and from the perspective of energy conservation, methods such as solar power generation and wind power generation are used to provide electrical energy for the dynamometer. However, the sensing unit is also in a high-temperature environment, which affects the operating efficiency of the sensing unit. On the contrary, the temperature difference between day and night is extremely large. At night, the sensing unit inside the dynamometer is in a low-temperature environment, which will also affect the operating efficiency in the sensing unit. Therefore, the present invention mainly optimizes the structure of the dynamometer in a low-temperature environment. The essence of the combined wind-water temperature control component in the present invention is to utilize the heat exchange principle for the heat exchange process. During the day when the temperature is relatively high, the water storage cover 6 mainly stores a water medium, and heat exchange is carried out between the water medium and the high-temperature environment inside the body 1 to achieve the purpose of cooling; on the contrary, when the temperature is relatively low at night, the heating module 8 heats the water medium, and the heated water medium conducts heat exchange with each sensing unit.

[0031] Embodiment 2: Supplementary description of the overall heat exchange process for the water storage cover:

[0032] An external motion structure 2 corresponding to the water storage cover 6 is installed at the external position of the body 1. The output shaft of the external motion structure 2 penetrates the body 1 and the water storage cover 6 and is fixedly connected to the center point position on one side of the directional partition block 10. The internal part of the heat exchange water storage is subdivided into a first-order temperature chamber and a second-order temperature chamber by the directional partition block 10. The installation position of the first-order temperature chamber is close to the installation position of the heat collection block 7. Both ends of the surrounding arc tube 5 correspond to the first-order temperature chamber and the second-order temperature chamber respectively. A heating module 8 is installed at the center point position of the outer wall of the directional partition block 10 corresponding to the first-order temperature chamber.

[0033] Scheme description: Combined with Figure 3 and Figure 4 for description. Since the structural specifications of the dynamometer are not completely unified, the surrounding arc tube 5 in the combined wind-water temperature control component needs to be structurally restricted according to the installation position of the sensing unit in the dynamometer. It should be noted that: The structural characteristics of the surrounding arc tube 5 change according to the structural contour and installation position of the sensing unit, but it is also necessary to ensure that both ends of the surrounding arc tube 5 are communicated with the inside of the heat exchange water storage. Therefore, the following explanations are made according to the two processes of heat dissipation and temperature rise:

[0034] Heat dissipation process: mainly for the day when the temperature is relatively high. In this process, the heating module 8 does not operate, and only the water medium is used for heat exchange during the heat exchange process, transferring the heat inside the body 1 to the water medium to play a cooling role;

[0035] Temperature rise process: mainly for the night when the temperature is relatively low. In this process, the heating module 8 continuously raises the temperature of the water medium, and then continuously conducts heat exchange with the sensing unit using the heated water medium, transferring the heat in the heated water medium to the sensing unit.

[0036] However, it should be noted again in combination with the above content that in the overall heat exchange process, the following also exists:

[0037] S1: Whether in the heat dissipation process or the heating process, the external motion structure 2 therein will be in a continuous motion process. The essence of the external motion structure 2 is an electric push rod structure, which is used to drive the directional partition block 10 to perform reciprocating linear displacement in the heat exchange water tank, and its purpose is to drive the water medium in the heat exchange water tank to continuously flow through the surrounding arc tube 5;

[0038] S2: Supplementary description based on the technical content in S1: First of all, the directional partition block 10 is not directly used as the piston structure in the heat exchange water tank, but a limiting cone block 9 is further added. Figure 5 Taking the directional partition block 10 located on the left side of the heat collection block 7 as an example, when it moves to the left, one of the limiting cone blocks 9 is completely blocked by the positive pressure from the water medium to block the corresponding convection channel, but the other limiting cone block 9 is opened by the negative pressure from the water medium to open the convection channel at this position. Thus, it can be directly understood that the water medium in the heat exchange water tank performs circular flow in the heat exchange water tank. Taking the top view direction of the heat exchange water tank as an example, when the directional partition block 10 moves to the left, the water medium can flow in the clockwise direction. However, in this process, the first-order temperature chamber and the second-order temperature chamber will also perform a small amount of flow in the surrounding arc tube 5.

[0039] Embodiment 3: Based on Embodiment 2, a supplementary description of the mixing heat process is as follows:

[0040] The directional partition block 10 is symmetrically provided with limiting cone blocks 9 along the width direction of the water storage cover 6, and the directional partition block 10 is internally provided with convection channels corresponding to the limiting cone blocks 9. A connecting spring 11 is arranged in the convection channels. One end position of the limiting cone block 9 is set as a frustum structure, and the setting direction of the frustum structure in the limiting cone block 9 is arranged in a staggered manner along the width direction of the water storage cover 6. The heat dissipation fan 3 is installed at an external position of the machine body 1, the air duct 4 is connected to the inside of the heat collection block 7, and a plurality of guide fins 12 are installed inside the heat collection block 7 along the width direction of the water storage cover 6. The guide fins 12 are wavy in the vertical direction, and the distances between the guide fins 12 are equal.

[0041] Scheme description: The following supplementary description is made in combination with S1 and S2 in Embodiment 2:

[0042] S3: During the heat dissipation process, the heat generated by the sensing unit can directly exchange heat with the water-based medium in the surrounding arc tube 5, which will cause the temperature of the water-based medium inside the surrounding arc tube 5 to continuously rise. During this process, the heat dissipation fan 3 can also be started. The purpose is to continuously generate a guiding air flow towards the external environment through the air duct 4, which can also drive the heat inside the body 1. When the directional partition block 10 is in a relatively static state, due to the temperature difference between the water-based medium in the surrounding arc tube 5 and the heat exchange water tank, an autonomous heat mixing process will occur. However, when the directional partition block 10 actively moves back and forth, the heat mixing process will be accelerated, so that the temperature of the water-based medium in the surrounding arc tube 5 is always lower than the temperature dissipated by the sensing unit;

[0043] S4: Based on the content of S3 and with reference to Figure 7 For illustration, the two air ducts 4 are arranged vertically in the heat collection block 7, and the formed guiding air flow will also directly act on the guiding fins 12 inside the heat collection block 7. The heat collection block 7 is always in contact with the water-based medium in the heat exchange water tank, so that the heat in the water-based medium in the heat exchange water tank can also be taken away. Further, the structural shape of the guiding fins 12 is limited to be wavy, mainly for extending the heat exchange process between the guiding air flow and the water-based medium in the heat exchange water tank;

[0044] S5: The key lies in the night environment with a relatively low temperature. During this process, the heat dissipation fan 3 is not started. Specifically, the heating module 8 is used to heat the water-based medium in the first-order temperature bin. However, during this process, when it is necessary to accelerate the cycle of the linear movement of the directional partition block 10, a simple explanation of the limiting cone block 9 is as follows: The convection channels corresponding to the limiting cone block 9 only serve as the flow channels for the water-based medium in the first-order temperature bin and the second-order temperature bin. However, by limiting the difference between the outer diameter of the limiting cone block 9 and the inner diameter of the convection channel, the flow rate of the water-based medium in the heat exchange water tank can be changed. The first purpose is to ensure the heat exchange and mixing process of the water-based medium in the first-order temperature bin and the second-order temperature bin. The second purpose is that when the directional partition block 10 moves to the left, the heated water-based medium in the first-order temperature bin will also flow clockwise in the surrounding arc tube 5, so as to output heat to the sensing unit with the heated water-based medium. The heat exchange water-based medium will also return to the second-order temperature bin. By changing the flow rate of the water-based medium during the flow process through the limiting cone block 9, it is ensured that the heated water-based medium fully accesses the surrounding arc tube 5 for heat exchange. However, it is also ensured that part of the heated water-based medium enters the second-order temperature bin to mix the water-based medium in the second-order temperature bin to maintain the water-based medium inside at a certain temperature value, avoiding the heat exchange water-based medium in the surrounding arc tube 5 directly entering the second-order temperature bin and affecting the heating process of the water-based medium in the first-order temperature bin, and ensuring the relative stability of the temperature of the water-based medium in the first-order temperature bin, the surrounding arc tube, and the second-order temperature bin during the overall flow and heat mixing process, and providing a relatively balanced temperature environment for the sensing unit.

[0045] In summary: The application scenario of the dynamometer used in oilfield exploitation operations is described, and a temperature control method is proposed specifically for the internal sensing unit. First, the combined method of air and water is used to reduce the ambient temperature inside the machine body. The purpose is to reduce the high temperature impact on the sensing unit during the operation of wind and light energy. Conversely, in the low temperature environment at night, based on the combined air and water structure, the heating action of the heating module is still coordinated to provide heat energy to multiple sensing units to maintain the operating state. The key technology of the present invention lies in: the mixed flow and mixed heat process of the water medium in the water storage cover realized by the directional partition block, or further changing the heat exchange process in cooperation with the air duct, heat collection block, and heating module. The purpose is to maintain the sensing stability of the dynamometer through the heat exchange process in high temperature / low temperature environments.
