DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.
[0022] See also Figure 1-3 , this patent provides a technical solution: a combined heat meter for a heat exchange station, including an integrator 1, a temperature sensor 2 and an ultrasonic flowmeter 3, the temperature sensor 2 and the ultrasonic flowmeter 3 are both electrically connected to the integrator 1 through a connecting line 4, and the integrator 1 is electrically connected to an external power supply;
[0023] The integrator 1, temperature sensor 2 and ultrasonic flowmeter 3 used in the device are all prior art, wherein the model of the integrator 1 is MIK-1158R, but is not limited to this model. The temperature of the water supply pipe and the return pipe in the heat exchange station is detected by the temperature sensor 3, and transmitted to the integrator 1 to obtain the temperature difference of the water flow. The flow rate of the water in the pipe can be detected by the ultrasonic flowmeter 3, and the flow rate value is transmitted to the integrator 1, and then the integrator 1 uses a specific calculation formula to calculate the heat obtained by the heat exchange system;
[0024] The formula is heat = water flow × temperature difference × heat capacity;
[0025] The lower wall of the ultrasonic flow meter 3 is provided with a mounting groove 5, a fixing box 6 is installed in the mounting groove 5, and a clearance groove 7 is provided on the upper wall of the fixing box 6. The sound wave generator and the sound wave receiver in the ultrasonic flow meter 3 are inserted into the fixing box 6 through the clearance groove 7;
[0026] A stopper 8 is slidably installed in the inner cavity of the fixed box 6, and a slide groove 9 is provided on the upper wall of the stopper 8. One end of a connecting rod 10 is slidably installed in the slide groove 9. The other end of the connecting rod 10 is installed on the inner wall of the fixed box 6. A spring 11 is sleeved on the outer side of the connecting rod 10. One end of the spring 11 is fitted with the inner wall of the fixed box 6, and the other end of the spring 11 is fitted with the upper wall of the stopper 8. The stopper 8 is fitted with the side walls of the sound wave generator and the sound wave receiver in the ultrasonic flowmeter 3;
[0027] By setting a fixing box 6 and a stopper 8 under the ultrasonic flow meter 3, the ultrasonic flow meter 3 can be closely fitted with the external pipeline when it is tied, thereby avoiding a gap between the ultrasonic flow meter 3 and the pipeline, preventing the ultrasonic flow meter 3 from shaking and affecting the measurement result;
[0028] The spring 11 can provide a downward thrust to the stopper 8, so that it can fit tightly with the side wall of the pipeline, avoiding a gap between the lower wall of the ultrasonic flowmeter 3 and the pipeline;
[0029] In addition, the stopper 8 in this article can slide up and down, so that it can change the curvature of the lower wall, so that the device can be tied to pipes of different sizes, thereby improving applicability;
[0030] The side wall of the fixing box 6 is screwed with a bolt 12, and the bolt 12 can fit with the side wall of the stopper 8;
[0031] By tightening the bolt 12 , the position of the stopper 8 can be fixed.
[0032] Specifically, two temperature sensors 2 and two ultrasonic flow meters 3 are provided, and the two temperature sensors 2 are respectively inserted into the water supply pipe and the water return pipe of the external heat exchange station. The outer sides of the two ultrasonic flow meters 3 are installed with a binding band 13, and the two ultrasonic flow meters 3 are tied to the outside of the water supply pipe of the external heat exchange station through the binding band 13;
[0033] The values detected by the two temperature sensors 2 are transmitted to the integrator 1 and the temperature difference of the water flows in the two pipes is obtained. The two ultrasonic flow meters 3 can detect the water flow rate of the water flows in the pipes and transmit it to the integrator 1.
[0034] Specifically, the strap 13 includes a strap body 131 and a Velcro 132. A through slot 14 is provided on the side wall of the ultrasonic flow meter 3. The strap body 131 is inserted and installed in the through slot 14. Velcro 132 is installed on both sides of the strap body 131. The two Velcro 132 can fit each other.
[0035] The ultrasonic flowmeter 3 in the present device is fixed to the pipe by means of a binding strap body 131 and Velcro 132. Compared with fixing by means of a pipe clamp, fixing by means of the binding strap 13 is more convenient and quicker, and can be quickly disassembled, making it convenient to maintain the ultrasonic flowmeter 3 or add coupling agent.
[0036] Specifically, the connecting rod 10 includes a rod body 101, a limit block 102, a roller frame 103 and a roller 104. One end of the rod body 101 is installed on the inner wall of the fixing box 6, and the other end of the rod body 101 is inserted and installed in the slide groove 9. The limit block 102 is installed on the end of the rod body 101 located in the slide groove 9. The roller frame 103 is installed on both sides of the limit block 102. The roller 104 is rotatably installed on the inner side of the roller frame 103, and the roller 104 is in contact with the inner wall of the slide groove 9.
[0037] By providing the roller frame 103 and the roller 104 , the friction force of the connecting rod 10 when sliding in the sliding groove 9 can be reduced to avoid jamming.
[0038] Specifically, a sealing gasket 15 is fitted on the lower wall of the stopper 8;
[0039] By providing the sealing gasket 15 , it can be ensured that the ultrasonic flowmeter 3 and the pipeline are in a sealed state, thereby preventing the entry of external impurities and preventing the measurement result of the ultrasonic flowmeter 3 from being affected.
[0040] Specifically, a connecting plate 16 is installed on the side wall of the integrator 1 , and screws 17 are inserted and installed into the side wall of the connecting plate 16 . The integrator 1 can be fixed to the external wall by the screws 17 .
[0041] Working principle: When in use, first install the two temperature sensors 2 on the water supply pipe and the return pipe in the heat exchange station respectively, and then fix the two ultrasonic flow meters 3 on the outside of the water supply pipe by the binding straps 13. During the binding process, the block 8 will be pushed into the fixing box 6. At this time, the block 8 fits tightly with the side wall of the pipe, and then tighten the bolts 12 to fix the position of the block 8 to complete the installation of the ultrasonic flow meter 3. The temperature sensor 3 detects the temperature in the water supply pipe and the return pipe in the heat exchange station, and transmits it to the integrator 1 to obtain the temperature difference of the water flow. The ultrasonic flowmeter 3 can detect the flow rate of water in the pipe, and transmit the flow value to the integrator 1. Then the integrator 1 uses a specific calculation formula to calculate the heat obtained by the heat exchange system.
