Description

Technical Field

[0001] This invention relates to the field of oil pumping unit protection, and more particularly to a belt protection device for tower-type oil pumping units. Background Technology

[0002] A tower pumping unit, also known as a tower pumping unit, is a device used to extract crude oil or other liquids from an oil well. It typically consists of a vertical steel tower and a rod system suspended from the top. Tower pumping units usually use a belt drive system to transmit power and motion. Common belt protection measures for tower pumping units include protective covers, sealing covers, and safety shields. However, how to provide appropriate protection for the pumping unit belt in response to belt wear and environmental factors remains a problem that technicians urgently need to solve.

[0003] Chinese Patent Publication No. CN201048315Y discloses a protective cover for a pumping unit motor, comprising: a motor cover body approximately triangular in shape, covering the lower half of the motor belt's movement trajectory; a bracket connected to the lower end of the motor cover body, which is connected to the pumping unit base via the bracket; and a digital management and early warning device for pumping unit belt tension, comprising: a pumping unit base, a data cable, a motor intelligent control cabinet, an early warning sensor, a stop sensor, a sensor mounting bracket, a push rod, a pressure wheel, a pumping unit belt, a bracket, a sensing block, and a spring. This device, through a pumping unit belt tension displacement measuring device, quantitatively manages the tension of the pumping unit belt during transmission, integrating pumping unit belt management into a central control room digital management platform. While the above technical solutions disclose protective covers for environmental factors and management and early warning devices for adjusting belt tension based on usage, they suffer from the following problem: the protective devices cannot be adjusted according to actual usage, resulting in poor belt protection. Summary of the Invention

[0004] To address this issue, the present invention provides a tower-type pumping unit belt protection device to overcome the problems in the prior art where belt protection is poorly targeted and cannot be adjusted according to the actual performance of the belt and the degree of influence of environmental factors, resulting in poor protection effect of the protection device.

[0005] To achieve the above objectives, the present invention provides a belt protection device for a tower-type pumping unit, comprising:

[0006] The belt protection unit, which is connected to the target pumping unit, includes a protective shielding module for shielding the belt and a ventilation module for controlling the amount of air blown onto the belt.

[0007] The data acquisition unit is connected to the target pumping unit and the belt protection unit to acquire demand analysis information, which includes the displacement distance of the pumping unit counterweight, the movement length of the drive wheel, the belt image, the belt vibration frequency, the ambient wind speed, the ambient temperature, the ambient humidity, and the ambient wind direction.

[0008] A data analysis unit, which is connected to the belt protection unit and the data acquisition unit respectively, is used to determine the data analysis mode based on the belt stability within a single monitoring cycle.

[0009] The first control and adjustment unit is connected to the belt protection unit, the data acquisition unit and the data analysis unit respectively. It is used to determine the magnitude of the tension adjustment coefficient according to the belt wear parameters and to determine the corresponding tension adjustment coefficient when adjusting the belt tension according to the maximum deviation difference. When the belt tension adjustment is completed, the belt tension adjustment is tested according to the belt control response degree to see if the belt tension adjustment is qualified.

[0010] The second control and adjustment unit is connected to the belt protection unit, the data acquisition unit, and the data analysis unit, respectively. It is used to determine the working mode of the belt protection unit according to the current environmental reference value. When the environmental reference value is in the second environmental reference value state, it determines whether the ventilation module is turned on according to the environmental wind direction, determines the number of ventilation modules to be turned on according to the environmental temperature, and determines the opening amplitude of the ventilation module according to the belt vibration frequency.

[0011] Furthermore, the data analysis unit periodically determines the data analysis mode based on the belt stability within a single monitoring cycle;

[0012] If the belt stability is within the first preset stability reference range, the data analysis unit determines to adopt the first data analysis mode.

[0013] If the belt stability is within the second preset stability reference range, the data analysis unit determines to adopt the second data analysis mode.

[0014] The data analysis unit has a monitoring cycle, the duration of which is T, where T > 0.

[0015] Furthermore, the formula for calculating the belt stability K is as follows:

[0016]

[0017] Where i = 1, 2, 3, ..., n, n > 0, n is the number of strokes of the tower-type pumping unit in a single monitoring cycle, Li is the belt travel distance length corresponding to the i-th stroke, and L0 is the preset belt travel distance length.

[0018] Furthermore, the first control and adjustment unit detects belt wear parameters under the first control and adjustment conditions and determines the tension adjustment coefficient based on the belt wear parameters;

[0019] The tension adjustment coefficient is negatively correlated with the belt wear parameters;

[0020] The first control adjustment condition is that the belt stability is within the second preset stability reference range.

[0021] Furthermore, under the second control and adjustment conditions, the first control and adjustment unit extracts the maximum belt deviation distance and calculates the difference between the maximum belt deviation distance and the allowable belt deviation distance, which is recorded as the maximum deviation difference. The first control and adjustment unit determines the tension adjustment coefficient corresponding to the belt tension adjustment based on the maximum deviation difference.

[0022] If the maximum deviation difference is within the first deviation distance range, the first control adjustment unit determines to use the first tension adjustment coefficient to adjust the belt tension.

[0023] If the maximum deviation difference is within the second deviation distance range, the first control adjustment unit determines to use the second tension adjustment coefficient to adjust the belt tension.

[0024] If the maximum deviation difference is within the third deviation distance range, the first control adjustment unit determines to use the third tension adjustment coefficient to adjust the belt tension.

[0025] The second control adjustment condition is that the tension adjustment coefficient has been determined.

[0026] Furthermore, the first control adjustment unit detects the belt control responsiveness under the third control adjustment condition. If the belt control responsiveness is less than the preset responsiveness, the first control adjustment unit determines to replace the belt and transmits the determination information to the user.

[0027] If the belt control responsiveness is greater than or equal to the belt responsiveness, the first control adjustment unit determines that the belt tension adjustment is qualified.

[0028] The third control adjustment condition is that the belt tension adjustment is completed.

[0029] Furthermore, the second control and adjustment unit determines the operating mode of the belt protection unit based on the current environmental reference value under the first environmental analysis conditions;

[0030] If the environmental reference value is in the first environmental reference value state, the second control adjustment unit determines to shut down the protective shielding module and the ventilation component.

[0031] If the environmental reference value is in the second environmental reference value state, the second control and adjustment unit determines the protective shielding module to be closed based on the ambient temperature and the ventilation module to be switched on or off based on the ambient wind direction.

[0032] If the ambient humidity is at the third preset ambient humidity, the second control and adjustment unit determines that the protective shielding modules are all in the open state.

[0033] Wherein, the first environmental reference state is that the environmental humidity is greater than the preset environmental humidity and / or the environmental wind speed is greater than the preset environmental wind speed; the second environmental reference state is that the environmental humidity is less than or equal to the preset environmental humidity, the environmental wind speed is less than or equal to the preset environmental wind speed, and the environmental temperature is greater than the preset environmental temperature; the third environmental reference state is that the environmental humidity is less than or equal to the preset environmental humidity, the environmental wind speed is less than or equal to the preset environmental wind speed, and the environmental temperature is less than or equal to the preset environmental temperature; and the first environmental analysis condition is that the belt stability is within the second preset stability reference range.

[0034] Furthermore, the second control and adjustment unit determines whether the ventilation module should be turned on based on the ambient wind direction under the second environmental analysis conditions.

[0035] If the ambient wind direction is in the first preset ambient wind direction state, the second control and adjustment unit determines to turn on the ventilation module;

[0036] If the ambient wind direction is in the second preset ambient wind direction state, the second control and adjustment unit determines to turn off the ventilation module;

[0037] The second environmental analysis condition is the second environmental reference quantity state.

[0038] Furthermore, under the third environmental analysis conditions, the second control and adjustment unit determines the number of ventilation modules to be turned on based on the ambient temperature;

[0039] The number of ventilation modules that are turned on is positively correlated with the ambient temperature;

[0040] The third environmental analysis state is when the environmental wind direction is in the first preset environmental wind direction state.

[0041] Furthermore, under the fourth environmental analysis conditions, the second control and adjustment unit determines the opening amplitude of the ventilation module based on the belt vibration frequency;

[0042] The opening amplitude of the ventilation module is negatively correlated with the vibration frequency of the belt;

[0043] The fourth environmental analysis condition is that the number of ventilation modules to be turned on has been determined.

[0044] Compared with the prior art, the beneficial effects of the present invention are as follows: the data analysis unit in the technical solution of the present invention determines the data analysis mode based on the belt stability within a single monitoring cycle, making the working mode of the present invention more in line with the actual working scenario and avoiding the efficiency reduction caused by troubleshooting one fault at a time. Furthermore, in the present invention, the first control adjustment unit determines the magnitude of the tension adjustment coefficient based on the belt wear parameters and determines the corresponding tension adjustment coefficient when adjusting the belt tension based on the maximum deviation difference, making the adjustment of the belt tension more targeted and the adjustment effect better. At the same time, the second control adjustment unit determines the working mode of the belt protection unit based on the current environmental reference value, avoiding the negative impact of excessive environmental humidity and wind speed on belt movement. In addition, the setting of the ventilation module strives to eliminate the inability of existing belt protection devices to effectively achieve both protection and cooling effects simultaneously, further improving the belt protection effect of the present invention, thereby improving the belt utilization efficiency.

[0061] Several ventilation modules 7 are mounted on the side surfaces 8 of the first windproof component 4 and the second windproof component 5 via electronic hinges, and are used to change the amount of wind blowing onto the belt 3 inside the protective shielding module by changing the on / off state of the ventilation modules.

[0062] Please continue reading. Figure 1 As shown, the data analysis unit periodically determines the data analysis mode based on the belt stability within a single monitoring cycle;

[0063] If the belt stability is within the first preset stability reference range, the data analysis unit determines to adopt the first data analysis mode.

[0064] If the belt stability is within the second preset stability reference range, the data analysis unit determines to adopt the second data analysis mode.

[0065] If the belt stability is within the third preset stability reference range, the data analysis unit determines that the belt working condition is qualified.

[0066] The data analysis unit has a monitoring cycle with a duration of T, where T > 0. Specifically, the preset stability reference range is defined by the following steps: the user extracts the belt stability values ​​from historical work records that meet the user's requirements for the pumping unit's operating status; the sum of these belt stability values ​​is recorded, and the average stability value is calculated. Values ​​within the third preset stability reference range are all less than 40% of the average stability value; values ​​within the second preset stability reference range are all greater than or equal to 40% of the average stability value but less than 80% of the average stability value; and values ​​within the first preset stability reference range are all greater than or equal to 80% of the average stability value. The determination of whether the operating status meets the user's requirements is a conventional technical method. A method for determining whether the operating status meets the user's requirements is provided by detecting the pumping volume within each monitoring cycle. If the difference between the pumping volumes of each monitoring cycle meets the user's requirements, then the operating status meets the user's requirements.

[0067] Specifically, the formula for calculating the belt stability K is as follows:

[0068]

[0069] Where i = 1, 2, 3, ..., n, n > 0, n is the number of strokes of the tower-type pumping unit in a single monitoring cycle, Li is the belt travel distance length corresponding to the i-th stroke, and L0 is the preset belt travel distance length.

[0070] Specifically, the first control adjustment unit detects belt wear parameters under the first control adjustment condition and determines the tension adjustment coefficient based on the belt wear parameters;

[0071] The tension adjustment coefficient is negatively correlated with the belt wear parameters;

[0072] The first control adjustment condition is that the belt stability is within the second preset stability reference range.

[0073] Specifically, the formula for calculating the belt wear parameter P is P = T × H, where T is the belt usage time, H is the reduction in belt thickness, and the reduction in belt thickness is the difference between the original belt thickness and the current belt thickness. Belt thickness can be acquired through an image detection device. When the pumping unit belt slips due to wear, the belt's travel distance is usually shorter than under normal operating conditions. This is because, under slippage, the belt cannot effectively transmit power, resulting in partial or complete power loss. Slippage also reduces friction between the belt and the drive pulley, causing the belt to slide or slide incompletely, thus resulting in a shorter belt travel distance compared to normal operating conditions and affecting oil output. The monitoring cycle length can be set by the user according to the actual application scenario, but it should be ensured that the duration of a single monitoring cycle is greater than the duration of a single stroke of the tower-type pumping unit. The belt travel distance is the displacement distance of the tower-type pumping unit's counterweight, and the preset belt travel distance is the travel length of the drive pulley.

[0074] Specifically, under the second control and adjustment conditions, the first control and adjustment unit extracts the maximum belt deviation distance and calculates the difference between the maximum belt deviation distance and the allowable belt deviation distance, which is recorded as the maximum deviation difference. The first control and adjustment unit determines the tension adjustment coefficient corresponding to the belt tension adjustment based on the maximum deviation difference.

[0075] If the maximum deviation difference is within the first deviation distance range, the first control adjustment unit determines to use the first tension adjustment coefficient to adjust the belt tension.

[0076] If the maximum deviation difference is within the second deviation distance range, the first control adjustment unit determines to use the second tension adjustment coefficient to adjust the belt tension.

[0077] If the maximum deviation difference is within the third deviation distance range, the first control adjustment unit determines to use the third tension adjustment coefficient to adjust the belt tension.

[0078] The second control adjustment condition is that the tension adjustment coefficient has been determined.

[0079] Specifically, the maximum deviation value is the difference between the maximum belt travel distance detected in a single monitoring cycle and the minimum belt travel distance. The deviation distance range is determined by the user extracting the maximum deviation difference corresponding to each instance in the historical work records where the oil output of the pumping unit did not meet the user's requirements, calculating the sum of all maximum deviation differences and averaging them. Values ​​within the first deviation distance range are all less than 30% of this average value, values ​​within the second deviation distance range are all greater than or equal to 30% of this average value and less than 60% of this average value, and values ​​within the third deviation distance range are all greater than or equal to 60% of this average value. The first control adjustment unit has a first tension adjustment coefficient α1, a second tension adjustment coefficient α2, and a third tension adjustment coefficient α3, where 1 < α1 < α2 < α3. The values ​​of α1, α2, and α3 can be determined by the user according to the actual application scenario, but it should be ensured that the adjusted belt tension is less than the corresponding maximum allowable tension of the belt. The maximum allowable tension is the maximum tension that the belt can withstand.

[0080] Specifically, the first control adjustment unit detects the belt control responsiveness under the third control adjustment condition. If the belt control responsiveness is less than the preset responsiveness, the first control adjustment unit determines to replace the belt and transmits the determination information to the user.

[0081] If the belt control responsiveness is greater than or equal to the belt responsiveness, the first control adjustment unit determines that the belt tension adjustment is qualified.

[0082] The third control adjustment condition is that the belt tension adjustment is completed.

[0083] Specifically, the belt tension is adjusted by adjusting the tensioning wheel, which is easy for those skilled in the art to understand and will not be elaborated here. The belt control responsiveness is the difference in stability obtained by subtracting the belt stability in a single monitoring cycle after the belt tension is adjusted from the belt stability before the belt tension is adjusted. The preset responsiveness value is the difference between the belt stability before the belt tension is adjusted and the maximum value of the third preset stability reference range.

[0084] Specifically, the second control and adjustment unit determines the working mode of the belt protection unit based on the current environmental reference value under the first environmental analysis conditions;

[0085] If the environmental reference value is in the first environmental reference value state, the second control adjustment unit determines to shut down the protective shielding module and the ventilation component.

[0086] If the environmental reference value is in the second environmental reference value state, the second control and adjustment unit determines the protective shielding module to be closed based on the ambient temperature and the ventilation module to be switched on or off based on the ambient wind direction.

[0087] If the ambient humidity is at the third preset ambient humidity, the second control and adjustment unit determines that the protective shielding modules are all in the open state.

[0088] Wherein, the first environmental reference state is that the environmental humidity is greater than the preset environmental humidity and / or the environmental wind speed is greater than the preset environmental wind speed; the second environmental reference state is that the environmental humidity is less than or equal to the preset environmental humidity, the environmental wind speed is less than or equal to the preset environmental wind speed, and the environmental temperature is greater than the preset environmental temperature; the third environmental reference state is that the environmental humidity is less than or equal to the preset environmental humidity, the environmental wind speed is less than or equal to the preset environmental wind speed, and the environmental temperature is less than or equal to the preset environmental temperature; and the first environmental analysis condition is that the belt stability is within the second preset stability reference range.

[0089] Specifically, high humidity increases the belt's coefficient of friction, making it more viscous and potentially causing a water film or slippery substance to accumulate on its surface. This can lead to belt slippage or slippage during transmission, reducing transmission efficiency and affecting the pump's output. Excessive wind speed can cause belt vibration, and high temperatures negatively impact belt performance and lifespan. High temperatures soften, age, and deteriorate the belt's rubber material, causing it to lose elasticity and tensile strength. High temperatures also cause lubricant to evaporate, increasing friction and wear, and reducing transmission efficiency. The system provides a method for determining preset environmental humidity, wind speed, and temperature values ​​based on the specific application scenario. Users can extract the maximum environmental humidity, wind speed, and temperature from historical work records that meet their requirements for the pump's operating conditions, and these values ​​are recorded as the preset environmental humidity, wind speed, and temperature, respectively.

[0090] Specifically, the second control and adjustment unit determines whether to turn on the ventilation module based on the ambient wind direction under the second environmental analysis conditions.

[0091] If the ambient wind direction is in the first preset ambient wind direction state, the second control and adjustment unit determines to turn on the ventilation module;

[0092] If the ambient wind direction is in the second preset ambient wind direction state, the second control and adjustment unit determines to turn off the ventilation module;

[0093] The second environmental analysis condition is the second environmental reference quantity state.

[0094] Wherein, the first preset environmental wind direction state is when the angle between the current direction and the air intake direction of the ventilation module is less than or equal to 120° and greater than or equal to 80°, and the second preset environmental wind direction state is when the angle between the current direction and the air intake direction of the ventilation module is greater than 120° or less than 80°.

[0095] Specifically, the second control and adjustment unit determines the number of ventilation modules to be turned on based on the ambient temperature under the third environmental analysis conditions;

[0096] The number of ventilation modules that are turned on is positively correlated with the ambient temperature;

[0097] The third environmental analysis state is when the environmental wind direction is in the first preset environmental wind direction state.

[0098] Specifically, the second control and adjustment unit determines the opening amplitude of the ventilation module based on the belt vibration frequency under the fourth environmental analysis conditions;

[0099] The opening amplitude of the ventilation module is negatively correlated with the vibration frequency of the belt;

[0100] The belt vibration frequency can be detected using a grating vibration sensor. The grating vibration sensor is connected to the transmission wheel, and the vibration frequency of the transmission wheel is recorded as the belt vibration frequency. The fourth environmental analysis condition is that the number of ventilation modules to be turned on is determined, and the opening amplitude of the ventilation module is the minimum angle between the ventilation module and the plane of the first ventilation component it is installed on when it is turned on.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
