Description

Technical Field

[0001] The present application relates to the technical field of water source detection, and in particular to a water source flow rate testing and heating capacity evaluation device. Background Art

[0002] After the geothermal well drilling project is completed, measuring the geothermal water flow rate through pumping tests and evaluating its heating capacity are important tasks in geothermal heating projects. The triangular weir is an intuitive, stable and reliable flow measurement tool, which is widely used in water conservancy projects for flow monitoring. In previous work, the monitoring of water flow is often distinguished from the monitoring of temperature, and is usually carried out by manual recording. The geothermal well pumping test lasts for a long time, generally about 72 hours, so manual recording often has the characteristics of low recording efficiency and high error rate. Therefore, there is an urgent need for a device that can intelligently measure water flow and evaluate the heating capacity of water sources.

[0003] Triangular weirs are usually used for flow monitoring. They have the characteristics of stable operation, visual measurement process, and high accuracy. They are widely used in monitoring fixed-point flow in ditches in water conservancy projects. By using the working principle of the triangular weir and organically combining it with temperature transmitters, liquid level meters, and information collectors, it can effectively make up for the shortcomings of manual recording, record data efficiently and accurately, and on this basis form a device that can evaluate the heating capacity of water sources.

[0036] See also Figure 1 The water source flow rate testing and heating capacity evaluation device of the embodiment of the present application includes: a water tank 100, a triangular weir 110, a temperature sensor 200 and an information collector 400. The water tank 100 is a hollow structure with an opening at the top, one end of which is a water inlet end and the other end is a measuring end. The water inlet end of the water tank 100 is suitable for connecting to a water inlet pipe. The triangular weir 110 is arranged at the measuring end of the water tank 100, and a flow rate scale is preset on the outside of the triangular weir 110. The preset flow rate scale is arranged at intervals along the hypotenuse of the triangular weir 110. The temperature sensor 200 is arranged inside the water tank 100. The information collector 400 is arranged outside the water tank 100 and is connected to the temperature sensor 200. The water flow temperature inside the water tank 100 is measured.

[0037] In this embodiment, the principle of measuring flow by the triangular weir 110 is combined with the water tank 100 to form a movable, standardized water flow measurement tool. The flow can be read through the scale lines, and can also be automatically monitored and read by a data acquisition instrument. Automatic temperature monitoring is added, and flow monitoring and temperature monitoring are organically combined to form a tool for evaluating the heating capacity of a water source. Specifically, the water tank 100 of the present application is used to collect water flow in the pipe to be measured, and then flow out from the triangular weir 110 on the other side. When the water volume inside the water tank 100 reaches the 0 scale, the flow rate entering the water tank 100 from the pipe to be measured is the same as the flow rate flowing out of the water tank 100 from the triangular weir 110. The triangular weir 110 is preset with flow scales along the two oblique sides, and the water flow rate inside the pipe to be measured can be intuitively observed and obtained. It can measure the water flow rate of small rivers and pipes, and can be used multiple times in different environments. A temperature sensor 200 is arranged inside the water tank 100, and the temperature sensor 200 is connected to an information collector 400, so that the water tank 100 can detect the temperature of the water flow, providing the ability to evaluate water source heating.

[0038] In a specific embodiment, the water source flow rate testing and heating capacity evaluation device further includes: a liquid level meter 300, which is disposed inside the water tank 100 to monitor the height of the water flow liquid level inside the water tank 100.

[0039] In a specific embodiment, the water tank 100 is a cubic structure, and the water inlet end and the measuring end of the water tank 100 are respectively located at the two ends of the length direction of the water tank 100. The water inlet end and the measuring end of the water tank 100 are arranged along the flow direction of the water flow, so that the water flow enters the inside of the water tank 100 from the water inlet end of the water tank 100, and then flows out from the measuring end of the water tank 100. Since the water inlet end and the measuring end of the water tank 100 are respectively located at the two sides of the length direction of the water tank 100, the length of the water tank 100 is the same as the flow direction of the water flow inside the water tank 100. Therefore, the water inlet end and the measuring end of the water tank 100 located at the two ends of the longer distance can flow out from the triangular weir 110 at the measuring end after the water inside the water tank 100 is horizontally calm, so as to avoid the collected water churning inside the water tank 100 and flowing out of the triangular weir 110, thereby causing inaccurate measurement of the water flow. The height of the water tank 100 is 2-3 times the height of the triangular weir 110, and can store a large amount of water, so that when the water flows to the position of the triangular weir 110, the water plane can be kept horizontal.

[0040] In a specific embodiment, the information collector 400 includes: a housing, a data collection module, a calculation unit module and a display screen. The data collection module is arranged inside the housing, connected to the temperature sensor 200, and used to receive data from the temperature sensor 200. The calculation unit module is arranged inside the housing, connected to the data collection module, and used to process the information collected by the data collection module from the temperature sensor 200. The display screen is embedded outside the housing, and the display screen is connected to the data collection module to display the water flow temperature inside the water tank 100. In the data collector, after processing the collected water flow liquid level and temperature, it can be calculated that when the water flow temperature drops to a certain temperature (such as 8°C), the heat exchanged from the water flow can be obtained, and then the heat that can be provided to the heating user after cascade utilization or single use of heat pump lifting can be calculated.

[0041] In this embodiment, the liquid level meter 300 is connected to the information collector 400 to monitor the liquid level of the water flow. The liquid level of the water flow through the triangular weir 110 can be obtained through the liquid level height, and the water flow rate can be calculated through relevant fluid mechanics theories.

[0042] The information collector 400 is connected to the temperature sensor 200 and the liquid level meter 300 respectively through a shielded cable 410 .

[0043] In a specific embodiment, the water flow measurement device further includes: a level 500, which is used to ensure that the water flow and the horizontal plane inside the water tank 100 can maintain a horizontal state. The level 500 includes: a length level 500 and a width level 500. The length level 500 is set at the water inlet end of the water tank 100, and the width level 500 is set on one side of the length direction of the water tank 100. In this way, the horizontality of the water tank 100 in the length direction and the width direction can be corrected by the two levels 500 to ensure that the water surface inside the water tank 100 is parallel to the horizontal plane. Before measuring the water flow, since the water tank 100 is a cubic structure, the position of the water tank 100 is adjusted in conjunction with the two levels 500 so that the plane of the water flowing into the water tank 100 through the water inlet end of the water tank 100 is parallel to the horizontal plane, thereby ensuring that the water flow measured by the triangular weir 110 can be accurate.

[0044] In a specific embodiment, the water flow measurement device further includes: a lifting ring 120, which is arranged on the top of the water tank 100 and can be used to move the water tank 100 for use in multiple different environments. Specifically, there are multiple lifting rings, which are arranged at intervals along the length direction of the water tank 100, so that it is convenient to use multiple slings to hang on the lifting ring 120 on the top of the water tank 100 to move the water tank 100. In order to stably place the water tank 100 at the measurement position, multiple lifting rings 120 are symmetrically arranged along the length direction of the water tank 100, so that the force conditions of each lifting ring 120 set on the top of the water tank 100 are the same, so that the water tank 100 can be stably placed on the ground.

[0045] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
