Description

Technical Field

[0001] This utility model relates to the field of data acquisition technology, specifically to an automated device for acquiring temperature and pressure data in industrial control. Background Technology

[0002] Industrial circulating water systems are widely used in various fields, such as manufacturing and energy industries. In most industrial processes, circulating water systems play a crucial role in cooling equipment, cooling materials, or serving as a transport medium. An industrial circulating water system mainly consists of cooling towers, circulating water pumps, circulating water tanks, and various instrument valves. Cooling tower fans and circulating water pumps are the largest electricity consumers in industrial circulating water systems, accounting for over 95% of the total energy consumption.

[0003] The invention patent currently published under the number CN117215255B discloses an automated energy-saving and consumption-reducing operation control system for an industrial circulating water system, comprising: a data acquisition module for acquiring operating data of the industrial circulating water system at a preset frequency; a data processing module for preprocessing the operating data acquired at any given time to obtain preprocessed operating data corresponding to that acquisition time; and an optimization algorithm module for obtaining operating control parameters of a first device based on the preprocessed operating data corresponding to that acquisition time, the optimal water supply temperature range, and the optimal water supply pressure range of the circulating water. The parameter output module is used to convert the operating control parameters of the first device into different data types to obtain the converted operating control parameters. The control signal sending module is used to convert the converted operating control parameters into corresponding control signals and send the control signals to the corresponding first device in the industrial circulating water system. This addresses the problem that existing control methods for automatically reducing energy consumption in industrial circulating water systems only focus on energy saving and optimization of the circulating water pumps, neglecting the energy-saving control of the cooling tower fans. This fails to fully realize the energy-saving potential of the entire circulating water system and still falls short of true optimized control.

[0004] In the existing automated energy-saving and consumption-reducing operation control system of industrial circulating water system, the temperature sensor is fixed on the inner wall of the detection cylinder and can only monitor the temperature of the coolant at a fixed depth. However, there is a certain temperature difference in the coolant at different depths, which leads to a large error in the water temperature monitoring. In order to solve the above problems, this application proposes an automated device for temperature and pressure data acquisition in industrial control. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes an automated device for industrial control of temperature and pressure data acquisition. The upper temperature sensor moves up and down with the water surface height, continuously detecting the water surface temperature. At the same time, the inflation / deflation solenoid valve can automatically control the air pump to inflate and deflate the lower float, causing the lower temperature sensor to float and sink in the water under the guidance of the lifting guide column. This allows the lower temperature sensor to monitor the water temperature at different depths, thereby improving the accuracy of water temperature acquisition and solving the problems mentioned in the background art.

[0010] The lower sliding sleeve sidewall ring is provided with a lower temperature sensor, and the lower surface of the lower sliding sleeve is equipped with a lower floating plate for providing buoyancy.

[0019] 1. This utility model utilizes an upper floating plate to increase buoyancy on an upper sliding sleeve, allowing the upper sliding sleeve to float on the water surface and move up and down with the water level. An upper temperature sensor is inserted into the water, enabling the detection of the water surface temperature via the upper temperature sensor. Simultaneously, an air pump is connected to a lower floating plate via a connecting pipe and a spiral telescopic pipe. An air inflation / deflation solenoid valve automatically controls the air pump to inflate or deflate the lower floating plate. The buoyancy of the lower floating plate increases after inflation and decreases after deflation, allowing the lower temperature sensor to float and sink in the water under the guidance of the lifting guide column. This enables the monitoring of water temperature at different depths via the lower temperature sensor, thereby improving the accuracy of water temperature acquisition.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figure 1-4 As shown, the present invention proposes an automated device for industrial control temperature and pressure data acquisition, including a top fixed base 1, wherein a lifting guide column 2 is fixed at the center of the lower surface of the top fixed base 1.

[0029] The lifting guide column 2 is slidably provided with an upper sliding sleeve 3 and a lower sliding sleeve 5. The lower sliding sleeve 5 is located below the upper sliding sleeve 3. The upper temperature sensor 7 is provided around the side wall of the upper sliding sleeve 3. The upper floating plate 4 for providing buoyancy is installed on the lower surface of the upper sliding sleeve 3.

[0030] The lower sliding sleeve 5 is provided with a lower temperature sensor 8 on its side wall ring, and a lower floating plate 6 for providing buoyancy is installed on the lower surface of the lower sliding sleeve 5.

[0031] An air pump 11 is installed on the upper surface of the top fixed seat 1. The exhaust end of the air pump 11 is connected to a connecting pipe 13. The end of the connecting pipe 13 penetrates the cavity wall of the top fixed seat 1. The end of the connecting pipe 13 is connected to a spiral telescopic pipe 14. The end of the spiral telescopic pipe 14 is connected to the lower floating plate 6. An inflation / deflation solenoid valve 12 is installed on the connecting pipe 13. The inflation / deflation solenoid valve 12 is used for inflation / deflation control of the lower floating plate 6.

[0032] It should be noted that the lifting guide column 2 is inserted into the cooling circulation tank. The top and bottom of the lifting guide column 2 are fixed by the top fixing seat 1 and the bottom fixing seat 16, respectively. The upper floating plate 4 increases the buoyancy of the upper sliding sleeve 3, which allows the upper sliding sleeve 3 to float on the water surface and move up and down with the water level. The upper temperature sensor 7 is inserted into the water and the water surface temperature can be detected through the upper temperature sensor 7. At the same time, the air pump 11 is connected to the lower floating plate 6 through the connecting pipe 13 and the spiral telescopic pipe 14. The inflation and deflation solenoid valve 12 can automatically control the air pump 11 to inflate and deflate the lower floating plate 6. The buoyancy of the lower floating plate 6 increases after inflation and decreases after deflation. This allows the lower temperature sensor 8 to sink and float in the water under the guidance of the lifting guide column 2, so as to monitor the water temperature at different depths through the lower temperature sensor 8 and improve the accuracy of water temperature acquisition.

[0033] In this embodiment, as Figure 2 and Figure 3As shown, the upper sliding sleeve 3 and the lower sliding sleeve 5 are both surrounded by retractable telescopic connecting brackets 9, and each end of the telescopic connecting bracket 9 is equipped with a mounting base 10. The upper temperature sensor 7 and the lower temperature sensor 8 are respectively mounted on the lower surface of the mounting base 10.

[0034] It should be noted that the upper temperature sensor 7 and the lower temperature sensor 8 can be installed at the end of the telescopic connecting bracket 9 via the mounting base 10, thereby allowing the distance between the upper temperature sensors 7 and the lower temperature sensors 8 to be adjusted to adapt the detection range to the usage requirements.

[0035] In this embodiment, as Figure 4 As shown, a bottom fixing seat 16 is fixedly connected to the bottom of the lifting guide column 2, and the bottom fixing seat 16 is used to fix the bottom of the lifting guide column 2.

[0036] It should be noted that the bottom fixing seat 16 is used to fix the bottom of the lifting guide column 2.

[0037] In this embodiment, as Figure 4 As shown, the lifting guide column 2 is provided with a limiting plate 15, which is used to limit the lower floating plate 6.

[0038] It should be noted that the limiting plate 15 is used to limit the lower floating plate 6, to prevent the lower temperature sensor 8 from colliding with the bottom of the cooling circulation tank, and to improve the protection of the lower temperature sensor 8.

[0039] The working principle and usage process of this utility model are as follows: The lifting guide column 2 is inserted into the cooling circulation tank. The top and bottom of the lifting guide column 2 are fixed by the top fixing seat 1 and the bottom fixing seat 16, respectively. The upper floating plate 4 increases the buoyancy of the upper sliding sleeve 3, allowing the upper sliding sleeve 3 to float on the water surface and move up and down with the water level. The upper temperature sensor 7 is inserted in the water, and the water surface temperature can be detected through the upper temperature sensor 7. At the same time, the air pump 11 is connected to the lower floating plate 6 through the connecting pipe 13 and the spiral telescopic pipe 14. The air filling and emptying solenoid valve 12 can automatically control the air supply. Pump 11 inflates and deflates the lower float 6. The buoyancy of the lower float 6 increases after inflation and decreases after deflation, allowing the lower temperature sensor 8 to float and sink in the water under the guidance of the lifting guide column 2. This enables the lower temperature sensor 8 to monitor the water temperature at different depths, thereby improving the accuracy of water temperature acquisition. The upper temperature sensor 7 and the lower temperature sensor 8 are connected to the upper sliding sleeve 3 and the lower sliding sleeve 5 respectively through the telescopic connecting bracket 9, allowing the distance between the upper temperature sensor 7 and the lower temperature sensor 8 to be adjusted to adapt the detection range to the usage requirements.
