UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the shortcomings in prior art and provides a turbine flowmeter measurement detection device.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme: a turbine flowmeter measurement and detection device, including U base, the U base top is fixed with water measurement pipe, the U base top is opened with base arc groove, the fixed ring spare is fixed in the base arc groove inner wall, the fixed ring spare circumference surface is opened with the spin fixed groove, the spin fixed groove inner wall is rotatably connected with the driven screw piece, the driven screw piece one end is fixed with the driving bevel gear, the spin fixed groove one end circumference array is opened with the end moment track, the end moment track inner wall is slidably connected with the clamping tooth piece, the spin fixed groove inner wall is rotatably connected with the fastening spin disc, the fastening spin disc top is fixed with the intercept moment vortex piece, the intercept moment vortex piece surface is engaged with the driven rack, the driven rack top is fixed with the clamping tooth piece, the fastening spin disc bottom is opened with the bottom ring tooth groove, the bottom ring tooth groove surface is engaged with the driving bevel gear tooth groove.

[0006] Preferably, the bottom of the U base is fixed with a bottom ladder, the bottom of the bottom ladder is provided with a bottom buffer groove, the inner wall of the bottom buffer groove is fixed with a buffer pad, and the inner wall of the bottom buffer groove is slidably connected with a side friction element, and the top of the side friction element is fixed with a buffer pad. In the prior art, when the turbine flowmeter is detected on the workbench, vibration will inevitably occur due to various operations and mechanical movements. These vibrations will be transmitted to the bottom of the equipment, causing continuous collisions between the turbine flowmeter and the ground. This continuous collision not only produces a large amount of noise, which interferes with the working environment, but also adversely affects the turbine flowmeter itself and its connection with the water pipe. In particular, the reaction force generated by the collision weakens the fixing effect of the turbine flowmeter and the water pipe connection. With the passage of time, this loosening leads to water leakage at the connection, thereby affecting the measurement accuracy of the turbine flowmeter. Water leakage not only causes waste of water resources, but also affects the reading of the turbine flowmeter due to changes in fluid pressure, so that the measurement data is no longer accurate and reliable. In view of such problems, the utility model adopts the mode of installing a buffer pad to solve the problem. When the equipment vibrates, the vibration is first transmitted to the U base. The stability of the U base, as the starting point of the entire damping system, is crucial to the subsequent damping effect. The vibration is transmitted from the U base to the bottom ladder. The bottom ladder is a key component that connects the U base and the buffer pad and is responsible for further transmitting the vibration downward. Under the action of the bottom ladder, the buffer pads in the bottom buffer groove begin to play a role. These buffer pads are designed in an interlocking manner, that is, the upper and lower buffer pads are not directly opposite each other, but have a certain offset. This design has its unique features. When the bottom ladder moves downward due to vibration, the upper and lower buffer pads will produce a large amount of friction on the side. This friction plays a key role in effectively preventing the movement caused by vibration. Specifically, when the bottom ladder moves downward, the friction between the buffer pads will hinder this movement, converting part of the vibration energy into internal energy. At the same time, the buffer pads will deform when they are pressed. This deformation will convert part of the energy into elastic potential energy. Due to the internal friction characteristics of the rubber material, this part of the elastic potential energy will be further converted into internal energy during the release process. When the buffer pads begin to release the elastic potential energy, the friction between them again plays a role in preventing the rapid release of the elastic potential energy, converting it into internal energy. This process is a gradual energy reduction process. Through the coordinated action of each part, the purpose of reducing the impact of vibration is achieved, improving user experience and prolonging the service life of the equipment.

[0007] Preferably, the bottom ladder is provided with a limiting vertical groove on the side of the shock-absorbing groove, and the inner wall of the limiting vertical groove is slidably connected with a limiting position column, and one end of the limiting position column is fixed with the side of the side friction member; in the prior art, when the up-down movement distance caused by vibration is large, the strong vibration will cause intense and rapid pressure on the shock-absorbing pad, and since the shock-absorbing pad is made of elastic materials such as rubber, it will deform or even break when subjected to excessive pressure, which not only reduces the shock-absorbing effect of the shock-absorbing pad, but also affects the stability and service life of the entire device; specifically, when the vibration amplitude increases, the up-down movement distance of the bottom ladder will also increase, which will cause the shock-absorbing pad to be subjected to a large extrusion force in a short time, causing changes in its internal structure; if the extrusion force exceeds the bearing range of the shock-absorbing pad, cracks or breaks will occur on its surface or inside, which will further weaken the shock-absorbing performance of the shock-absorbing pad, making it unable to effectively absorb and disperse vibration energy; with the passage of time, the damage will gradually accumulate and intensify, eventually leading to the complete failure of the shock-absorbing pad, which not only affects the normal operation of the device, but also requires replacement of the new shock-absorbing pad, increasing the maintenance and use costs of the device; more seriously, if the shock-absorbing pad breaks at a critical position, it will cause the device to malfunction or safety accident, causing loss of personnel and property; in view of such problems, the utility model adopts the installation of the limiting position column to solve the problem, realizes the coordination between the limiting position column and the limiting vertical groove, limits the movement distance of the side friction member, and thus prevents the shock-absorbing pad from being damaged due to excessive pressure, achieving the effect of improving the service life of the device.

[0008] Preferably, one end of the limiting position column is fixed with a right-angle ladder fixture, and the bottom of the right-angle ladder fixture is fixed with the top of the side friction member, achieving the effect of improving the service life of the device by increasing the fixing effect of the limiting position column through the right-angle ladder fixture.

[0009] Preferably, the inner wall top and the inner wall bottom of the limiting vertical groove are both fixed with a buffer end pad, achieving the effect of improving the service life of the device by reducing the collision between the limiting position column and the limiting vertical groove.

[0010] Preferably, the bottom of the side friction member is fixed with a noise-reducing ladder pad, and the bottom of the noise-reducing ladder pad is provided with an anti-skid groove, achieving the effect of improving user experience by reducing the collision between the device and the ground.

[0011] Preferably, the bottom ladder is provided with a carrying groove on both sides, and a connecting edge table piece is fixed between the plurality of fixed ring pieces, achieving the effect of improving the service life of the device by facilitating transportation of the staff and preventing position deviation caused by shaking of the plurality of fixed ring pieces during transportation.

[0012] Beneficial effects:

[0013] 1. In existing technologies, turbine flow meters, as precision fluid measuring instruments, are crucial for ensuring accuracy and reliability in fields such as industrial process control, energy management, and environmental monitoring. Therefore, turbine flow meters must undergo rigorous metrological testing before use or after a period of use to ensure the accuracy of their readings. However, due to the existence of various models of turbine flow meters on the market, each with different diameters of their mechanical components connecting to water pipes, maintenance work faces certain challenges. If corresponding metrological testing equipment is purchased for each different model of turbine flow meter, the maintenance costs will increase significantly over time. This includes not only the direct cost of purchasing the equipment but also indirect costs such as storage, calibration, operation, and maintenance. Furthermore, different models of turbine flow meters require different testing standards and methods, demanding that maintenance personnel possess broader knowledge and skills, thus increasing labor costs. To address these issues, this utility model employs a method of installing clamping gears to solve... This solution enables operators to measure and test turbine flow meters by installing a water metering pipe of appropriate diameter on the top of the U-shaped base, then passing the turbine flow meter through the center of the fixed ring. Using a power screwdriver or similar tool, the driven screw is inserted and rotated. The rotation of the driven screw in the fixed groove causes the driving bevel gear to mesh with the bottom ring tooth groove of the fastening disc. This causes the rotating torque vortex of the fastening disc to move the driven rack, causing the clamping teeth to converge towards the center of the fixed ring, applying even pressure to the turbine flow meter and clamping it in place. The operator then fixes both ends of the turbine flow meter to the water metering pipe. Due to the shape and characteristics of the clamping teeth, pressure is applied evenly to the center, making it compatible with most turbine flow meter shapes and diameters on the market. It can effectively accommodate turbine flow meters with triangular, circular, and polygonal cross-sections. Furthermore, operators can adjust the driven screw by rotating it to accommodate turbine flow meters of different diameters, thus greatly increasing the applicability of the metering and testing equipment, reducing production costs, and achieving the effect of improving the equipment's applicability.

[0014] 2. In existing technologies, when a turbine flow meter is tested on a workbench, vibrations are inevitably generated due to various operations and mechanical movements. These vibrations are transmitted to the bottom of the equipment, causing continuous collisions between the turbine flow meter and the ground. This continuous collision not only generates significant noise and interferes with the working environment, but also adversely affects the turbine flow meter itself and its connection with the water pipe. In particular, the reaction force generated by the collision weakens the fixing effect at the connection between the turbine flow meter and the water pipe. Over time, this loosening leads to water leakage at the connection, which in turn affects the metering accuracy of the turbine flow meter. Water leakage not only wastes water resources, but also affects the reading of the turbine flow meter due to changes in fluid pressure, thus making the metering data inaccurate and unreliable. To address this problem, this utility model uses the installation of shock-absorbing elliptical pads. When the equipment vibrates, the vibration is first transmitted to the U-shaped base. The stability of the U-shaped base, as the starting point of the entire vibration damping system, is crucial for the subsequent vibration damping effect. The vibration is then transmitted from the U-shaped base to the bottom stepped platform, which is a key component connecting the U-shaped base and the shock-absorbing elliptical pads. It is responsible for further transmitting the vibration downwards. Under the action of the bottom stepped platform, the shock-absorbing elliptical pads in the bottom rectangular buffer groove begin to function. These shock-absorbing elliptical pads are designed to be fixed in a staggered manner, meaning that the upper and lower layers of shock-absorbing elliptical pads are not directly opposite each other, but are offset to a certain extent. This design has its unique advantages. When the bottom stepped platform moves downward due to vibration, the upper and lower layers of shock-absorbing elliptical pads will generate significant friction on the sides. This friction plays a crucial role, effectively preventing the movement caused by vibration. Specifically, when the bottom stepped platform moves downward, the friction between the shock-absorbing elliptical pads will hinder this movement, converting some of the vibration energy into internal energy. At the same time, the shock-absorbing elliptical pads will deform when compressed. This deformation will convert some of the energy into elastic potential energy. Due to the internal friction characteristics of rubber material, this elastic potential energy will be further converted into internal energy during the release process. When the shock-absorbing elliptical pads begin to release elastic potential energy, the friction between them will play a role again, preventing the rapid release of elastic potential energy and converting it into internal energy. This process is a gradual reduction of energy. Through the synergistic effect of various parts, the ultimate goal of reducing the impact of vibration is achieved, thereby improving the user experience and extending the service life of the equipment.

[0015] 3、In the prior art, when the up-and-down movement distance caused by vibration is large, the strong vibration will cause intense and rapid pressure on the shock-absorbing ellipsoidal pad. Since the shock-absorbing ellipsoidal pad is made of elastic materials such as rubber, it will deform or even break when bearing excessive pressure. Such breakage not only reduces the shock-absorbing effect of the shock-absorbing ellipsoidal pad, but also affects the stability and service life of the entire device. Specifically, when the vibration amplitude increases, the up-and-down movement distance of the bottom ladder platform will also increase, which will cause the shock-absorbing ellipsoidal pad to be subjected to a great extrusion force in a short time, causing changes in its internal structure. If the extrusion force exceeds the bearing range of the shock-absorbing ellipsoidal pad, cracks or breaks will occur on its surface or inside. These damages will further weaken the shock-absorbing performance of the shock-absorbing ellipsoidal pad, making it unable to effectively absorb and disperse vibration energy. With the passage of time, such damage will gradually accumulate and intensify, eventually leading to the complete failure of the shock-absorbing ellipsoidal pad. This not only affects the normal operation of the device, but also requires replacement of a new shock-absorbing ellipsoidal pad, increasing the maintenance and use costs of the device. More seriously, if the shock-absorbing ellipsoidal pad breaks at a critical position, it will cause the device to malfunction or safety accidents, causing loss of personnel and property. To solve such problems, the utility model adopts the installation of a limiting position column, which limits the movement distance of the side friction element through the coordination between the limiting position column and the limiting vertical groove, thereby preventing the shock-absorbing ellipsoidal pad from being damaged due to excessive pressure, and achieving the effect of improving the service life of the device.

[0024] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] The specific embodiments of the utility model are described below in combination with the drawings. Specific embodiments:

[0027] Reference Figures 1-6The utility model provides a kind of turbine flowmeter metering detection device, including U base 1, U base 1 top is fixed with water metering pipe 101, U base 1 top is set with base cam groove 2, the inner wall of base cam groove 2 is fixed with fixed ring piece 201, the circumferential surface of fixed ring piece 201 is set with spin slot 202, spin slot 202 inner wall is rotatably connected with driven screw piece 2010, driven screw piece 2010 one end is fixed with driving bevel gear 209, spin slot 202 one end circumferential array is set with end square track 203, end square track 203 inner wall is slidably connected with clamping tooth piece 207, spin slot 202 inner wall is rotatably connected with fastening spin disc 204, fastening spin disc 204 top is fixed with intercept square vortex piece 205, intercept square vortex piece 205 surface is engaged with driven rack 206, driven rack 206 top is fixed with clamping tooth piece 207, fastening spin disc 204 bottom is set with bottom ring tooth groove 208, and the surface of bottom ring tooth groove 208 is engaged with the tooth groove of driving bevel gear 209.The bottom of the U base 1 is fixed with a bottom ladder 3, and the bottom of the bottom ladder 3 is provided with a bottom damping groove 301, and the inner wall of the bottom damping groove 301 is fixed with a damping pad 303, and the inner wall of the bottom damping groove 301 is slidably connected with a side friction member 302, and the top of the side friction member 302 is fixed with a damping pad 303. When the turbine flowmeter is detected on the workbench, due to various operations and mechanical movements, vibration will inevitably occur, which will be transmitted to the bottom of the equipment, causing continuous collision between the turbine flowmeter and the ground. This continuous collision not only produces a lot of noise, which interferes with the working environment, but also has an adverse effect on the turbine flowmeter itself and its connection with the water pipe. In particular, the reaction force generated by the collision will weaken the fixing effect of the turbine flowmeter and the water pipe connection, and with the passage of time, this loosening will cause leakage at the connection, thereby affecting the measurement accuracy of the turbine flowmeter. The leakage not only causes waste of water resources, but also affects the reading of the turbine flowmeter due to the change of fluid pressure, so that the measurement data is no longer accurate and reliable. The installation of damping pad 303 solves the problem, and when the equipment vibrates, the vibration is first transmitted to the U base 1, which is the starting point of the entire damping system. Its stability is crucial to the subsequent damping effect. The vibration is transmitted from the U base 1 to the bottom ladder 3, which is the key component connecting the U base 1 and the damping pad 303, and it is responsible for further transmitting the vibration downward. Under the action of the bottom ladder 3, the damping pad 303 in the bottom damping groove 301 begins to play a role. These damping pads 303 are designed to be fixed in a staggered manner, that is, the upper and lower damping pads 303 are not directly opposite, but have a certain displacement. Such design has its unique features. When the bottom ladder 3 moves downward due to vibration, the upper and lower damping pads 303 will produce a lot of friction on the side. This friction plays a key role in effectively preventing the movement caused by vibration. Specifically, when the bottom ladder 3 moves downward, the friction between the damping pads 303 will hinder this movement, converting part of the vibration energy into internal energy. At the same time, the damping pad 303 will deform when it is pressed, and this deformation will convert part of the energy into elastic potential energy. Due to the internal friction characteristics of the rubber material, this part of the elastic potential energy will be further converted into internal energy during the release process. When the damping pad 303 begins to release the elastic potential energy, the friction between them plays a role again, converting the elastic potential energy into internal energy. This process is a gradual energy reduction process. Through the cooperation of each part, the purpose of reducing the impact of vibration is achieved, and the user experience and equipment service life are improved.

[0028] The bottom of the limiting vertical groove 304 is provided with a limiting vertical groove 304, and the inner wall of the limiting vertical groove 304 is slidably connected with a limiting position column 305. One end of the limiting position column 305 is fixed with the side of the side friction member 302. When the up-down moving distance caused by vibration is large, the strong vibration will cause severe and rapid pressure on the shock-absorbing elliptical pad 303. Since the shock-absorbing elliptical pad 303 is made of elastic materials such as rubber, it will deform or even break when subjected to excessive pressure. This breakage not only reduces the shock-absorbing effect of the shock-absorbing elliptical pad 303, but also affects the stability and service life of the entire device. Specifically, when the vibration amplitude increases, the up-down moving distance of the bottom ladder 3 will also increase, which will cause the shock-absorbing elliptical pad 303 to be subjected to a large extrusion force in a short time, causing changes in its internal structure. If the extrusion force exceeds the bearing range of the shock-absorbing elliptical pad 303, cracks or fractures will occur on its surface or inside. These damages will further weaken the shock-absorbing performance of the shock-absorbing elliptical pad 303, making it unable to effectively absorb and disperse vibration energy. With the passage of time, these damages will gradually accumulate and intensify, eventually leading to the complete failure of the shock-absorbing elliptical pad 303. This not only affects the normal operation of the device, but also requires replacement of the new shock-absorbing elliptical pad 303, increasing the maintenance and use cost of the device. More seriously, if the shock-absorbing elliptical pad 303 breaks at a critical position, it will cause the device to malfunction or safety accident, causing loss of personnel and property. By installing the limiting position column 305, the movement distance of the side friction member 302 is limited through the coordination between the limiting position column 305 and the limiting vertical groove 304, thereby preventing the shock-absorbing elliptical pad 303 from being damaged due to excessive pressure, and improving the service life of the device. One end of the limiting position column 305 is fixed with a right-angle ladder fixture 307, and the bottom of the right-angle ladder fixture 307 is fixed with the top of the side friction member 302. The right-angle ladder fixture 307 increases the fixing effect of the limiting position column 305, thereby improving the service life of the device. The inner wall top and bottom of the limiting vertical groove 304 are fixed with a buffer end pad 306, which reduces the collision between the limiting position column 305 and the limiting vertical groove 304, thereby improving the service life of the device. The bottom of the side friction member 302 is fixed with a noise-reducing ladder pad 308, and the bottom of the noise-reducing ladder pad 308 is provided with an anti-skid groove, which reduces the collision between the device and the ground, thereby improving the user experience. The two sides of the bottom ladder 3 are provided with carrying grooves 401, and a plurality of fixed ring members 201 are fixed with a connecting edge table member 4, which facilitates transportation of the staff and prevents position deviation caused by shaking of the plurality of fixed ring members 201 during transportation, thereby improving the service life of the device.

[0029] The utility model discloses a working principle: when the staff needs to measure and detect turbine flowmeter, install the water measuring pipe 101 of suitable diameter on the top of U base 1, then make the turbine flowmeter pass through the center of solid ring piece 201, then use electric screwdriver and the like to insert passive screw piece 2010 and rotate, and the rotation of passive screw piece 2010 in the rotation groove 202 makes the driving bevel gear 209 mesh with the bottom ring tooth groove 208 at the bottom of fastening rotary disc 204 when rotating, makes fastening rotary disc 204 rotate torque vortex piece 205 and drive rack 206, makes clamping tooth piece 207 gather to the center of solid ring piece 201, and the even pressure to turbine flowmeter is clamped, and the turbine flowmeter is fixed under pressure, then the staff fixes the both ends of turbine flowmeter with water measuring pipe 101, because of the morphological characteristics of clamping tooth piece 207, can even the pressure to the center, so that it can adapt to the shape and diameter of most turbine flowmeters on the market, can better adapt to the shape of turbine flowmeter of triangular, circular and polygonal section, and the staff can adjust passive screw piece 2010 by rotating to adapt to turbine flowmeters of different diameters, thereby greatly increasing the application range of the measuring and detecting equipment.
