DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application will be further described below in combination with specific embodiments.
[0023] Embodiment one: please refer to Figures 1-5 The specific embodiments of the application are as follows: The structure includes main body 1, flow meter 2, instrument 3, the top of the main body 1 is provided with flow meter 2, and the instrument 3 is connected to the front end face of the flow meter 2.
[0024] The main body 1 includes a connecting pipe 11, an installation pipe 12, a measuring device 13, and a fixing ring 14. The top end face of the connecting pipe 11 is provided with the installation pipe 12, which is connected to the bottom end face of the flow meter 2. The measuring device 13 is fixedly installed on the inner end face of the installation pipe 12. There are two fixing rings 14, which are respectively fixedly connected to the left and right end faces of the installation pipe 12. The inner width of the installation pipe 12 gradually decreases from the outside to the inside. The end face of the fixing ring 14 is provided with a threaded hole, which is beneficial for measuring the flow rate of water flowing through the connecting pipe 11 and improving the accuracy of the pump station flow rate measurement.
[0025] The mounting pipe 12 includes a fixing seat 121, a pipe body 122, a locking block 123, and a threaded frame 124. The fixing seat 121 is welded to the top end face of the connecting pipe 11. The top end face of the pipe body 122 is connected to the flow meter 2, and the bottom end face of the pipe body 122 is connected to the end face of the measuring device 13. The locking block 123 is fixedly connected to the side end face of the pipe body 122. The threaded frame 124 is threaded to the end face of the fixing seat 121, and the inner end face of the threaded frame 124 engages with the locking block 123. The width of the locking block 123 is greater than the inner width of the fixing seat 121, which helps the pipe body 122 to drive the end face of the measuring device 13 to fit tightly against the inner end face of the connecting pipe 11 for fixation.
[0026] The fixed base 121 includes a fixed ring a1, a threaded block a2, and a buffer block a3. The fixed ring a1 is welded to the top end face of the connecting pipe 11. The threaded block a2 is disposed on the outer end face of the fixed ring a1. The buffer block a3 is installed on the inner end face of the fixed ring a1. The buffer block a3 is made of rubber and is circular, which helps to reduce the vibration amplitude of the pipe body 122 and avoid affecting the measurement of water flow by the measuring device 13.
[0027] The buffer block a3 includes a support base a31, a support ring a32, and a support pad a33. The support base a31 is fixedly connected to the inner bottom end of the fixed ring a1. There are seven support rings a32, which are arranged vertically on the end face of the support base a31. The support pad a33 is disposed between two support rings a32. The width of the support pad a33 gradually increases from the upper and lower ends to the middle position, and the inner side of the support pad a33 is hollow, which helps to buffer the measuring device 13 and reduce the vibration experienced by the measuring device 13.
[0028] Based on the above embodiments, the specific working principle is as follows: A fixing ring 14 is bolted to the pipeline of the pump station. A measuring device 13 is installed inside the connecting pipe 11 to measure the flow rate of the water flowing through the connecting pipe 11, thereby measuring the flow rate of the pump station. Then, a threaded frame 124 is rotated towards the lower end of the fixing seat 121, causing the end face of the fixing seat 121 to press the clamping block 123 downwards. This causes the pipe body 122 to tightly press the end face of the measuring device 13 against the inner end face of the connecting pipe 11 for fixation. Finally, the threaded frame 124 presses against the end face of the clamping block 123, allowing the end face of the clamping block 123 to... The support a31 fits snugly against the end face of the buffer block a3. When the buffer block a3 is subjected to vibration, it can be squeezed and deformed, reducing the vibration amplitude of the tube body 122 and avoiding affecting the measurement of water flow by the measuring device 13. Finally, the support a31 supports the end face of the clamping block 123, so that when the measuring device 13 is vibrated, the tube body 122 can drive the clamping block 123 to squeeze the end face of the support ring a32, causing the support ring a32 to squeeze the end face of the support pad a33 and deform, thus buffering the measuring device 13, reducing the vibration of the measuring device 13, and improving the accuracy of the measuring device 13 in measuring flow.
[0029] Example 2: Please refer to Figures 6-7 The specific embodiments of the present invention are as follows: The measuring device 13 includes a protective frame s1, a flow sensor s2, and a shock-absorbing device s3. The end face of the protective frame s1 is connected to the end face of the pipe body 122. The flow sensor s2 is disposed on the inner end face of the protective frame s1. The shock-absorbing device s3 is nested on the outer end face of the protective frame s1. The shock-absorbing device s3 is made of rubber and is annular, which helps to cushion the flow sensor s2 when it is subjected to vibration by squeezing the shock-absorbing device s3 to cause deformation and reduce the vibration amplitude of the flow sensor s2.
[0030] The shock absorption device s3 includes a shock absorption block s31, a buffer groove s32, and a friction groove s33. The shock absorption block s31 is nested on the outer end face of the protective frame s1. There are two or more buffer grooves s32, which are arranged on the inner end face of the shock absorption block s31. There are eight or more friction grooves s33, which are arranged on the inner and outer ends of the shock absorption block s31. The buffer groove s32 is elliptical, and the end face of the friction groove s33 is semi-circular, which helps the shock absorption block s31 to deform into the friction groove s33, thereby increasing the shock absorption effect on the flow sensor s2.
[0031] Based on the above embodiments, the specific working principle is as follows: A protective frame s1 is used to prevent slippage on the end face of the flow sensor s2, avoiding water ingress into the connection lines of the flow sensor s2. A shock-absorbing device s3 is then used to cover the end face of the protective frame s1, allowing the flow sensor s2 to be compressed and deformed when subjected to vibration, thus reducing the vibration amplitude and enabling the flow sensor s2 to accurately measure the flow rate of the pumping station. A shock-absorbing block s31 is also used to protect the flow sensor s2. When the flow sensor s2 is subjected to vibration, the shock-absorbing block s31 is compressed and deformed towards the end face of the buffer groove s32, reducing the vibration intensity. Furthermore, the friction groove s33 allows the shock-absorbing block s31 to fit tightly against the end face of the protective frame s1 and also allows the shock-absorbing block s31 to deform into the friction groove s33, increasing the shock absorption effect on the flow sensor s2 and enabling the flow sensor s2 to accurately measure the water flow rate of the pumping station.
[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0033] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
