Description

Technical Field

[0001] The present application relates to the technical field of pressure sensors, and in particular to a pressure sensor bracket. Background Art

[0002] At present, the inlet and outlet pressures of water pumps are tested by transmitting signals through pressure sensors. Pressure sensors are devices or apparatuses that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules.

[0003] When the pressure sensor is measuring pressure, it is screwed directly onto the pressure measuring tube. Each time a water pump with a different caliber is measured, the sensor must be disassembled and then reinstalled on the pressure measuring tube. Existing sensors are disassembled and installed many times during use, which can easily damage the sensor connection thread part. Frequent disassembly can easily damage the pressure sensor thread part or even cause it to be scrapped, resulting in the device being unable to be used normally. Damage to the components will lead to a large consumption of accessories, increasing the maintenance cost of the sensor.

[0004] In existing use, the pressure measuring tube of the sensor is usually installed at the inlet and outlet of the water pump. Since the sensor is located close to the inlet and outlet of the water pump, large pressure fluctuations can easily cause unstable test data of the sensor and cause data errors, thereby affecting the test effect.

[0048] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application and how the technical solutions in the present application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0049] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0050] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0051] When the pressure sensor is measuring pressure, it is screwed directly onto the pressure measuring tube. Each time a water pump of a different diameter is measured, the sensor must be disassembled and then reinstalled on the pressure measuring tube.

[0052] Existing sensors are disassembled and installed many times during use, which can cause the sensor connection thread part to be easily damaged. Frequent disassembly can easily cause the pressure sensor thread part to be damaged or even scrapped, causing the device to be unable to be used normally. Damage to components will lead to a large consumption of accessories, increasing the maintenance cost of the sensor.

[0053] In existing use, the pressure measuring tube of the sensor is usually installed at the inlet and outlet of the water pump. Since the sensor is located close to the inlet and outlet of the water pump, large pressure fluctuations can easily cause unstable test data of the sensor and cause data errors, thereby affecting the test effect.

[0054] Therefore, the embodiment of the present application provides a pressure sensor bracket, which is fixed on the base by setting a connecting component and a supporting component, wherein the connecting component includes: an inlet conduit and an outlet conduit, which are used to connect the pressure measuring tube; the supporting component includes: a first supporting device and a second supporting device, the first supporting device is provided with a first supporting member for fixing and supporting a pressure sensor for measuring the inlet pressure, and the second supporting device is provided with at least two supporting members for fixing and supporting at least two pressure sensors of different pressure levels for measuring the outlet pressure; when in use, the inlet end and the outlet end of the pressure measuring tube are connected to the inlet conduit and the outlet conduit respectively, and the inlet pressure and the outlet pressure are measured by the pressure sensor fixed on the bracket, wherein, when measuring the outlet pressure, the corresponding stop valve is opened according to the required pressure level, and other stop valves are closed, so that the corresponding pressure sensor continues to measure. Installing the sensor on a specific bracket avoids the problem of test data errors caused by unstable pressure, while reducing the disassembly of the sensor, reducing the probability of scrapping the sensor and saving work costs.

[0055] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the present application provides a pressure sensor bracket, including a base 100, a connecting assembly 200 and a supporting assembly 300, wherein one end of the connecting assembly 200 is fixedly connected to the base 100; the connecting assembly 200 includes: an inlet conduit 210 and an outlet conduit 220; the supporting assembly 300 includes: a first supporting device 310, a second supporting device 320 and a sealing plate 330, wherein the bottom end of the first supporting device 310 is movably connected to the top end of the inlet conduit 210, and the bottom end of the second supporting device 320 is movably connected to the top end of the outlet conduit 220, and the supporting assembly 300 is used to support a pressure sensor, and the pressure sensor is used to measure the water inlet pressure of the inlet conduit 210 or the water outlet pressure of the outlet conduit 220; the side ends of the first supporting device 310 and the second supporting device 320 are fixedly connected to the two sides of the sealing plate 330 respectively.

[0057] In the embodiment of the present application, the base 100 is kept level with the ground to ensure the stability of the entire bracket during use. The connecting component 200 is fixedly connected to the base 100. The connecting component 200 can be fixed to the base 100 by welding, threaded connection or other methods. The connecting part thereof needs to be fixed to the base 100 to ensure the stability of the entire system. The specific connection method is not limited here.

[0058] Among them, the lengths of the water inlet conduit 210 and the water outlet conduit 220 can be the same length, which are used to guide the flow medium in the pressure measuring tube to flow in and out, respectively, and introduce the flow medium into the support assembly 300, so that the pressure sensor fixed on the support assembly 300 can calibrate the pressure of the flow medium.

[0059] Specifically, the first supporting device 310 and the second supporting device 320 are used to support and fix the inlet pressure sensor and the outlet pressure sensor, respectively, to ensure that the sensors can accurately measure the pressure of the flowing medium introduced into the water inlet conduit 210 and the water outlet conduit 220. The first supporting device 310 and the second supporting device 320 are movably connected to the top of the corresponding water inlet conduit 210 and the water outlet conduit 220, for example, the connection adjustment can be achieved through some adjustment mechanism, such as thread, buckle, etc., to adapt to sensors of different sizes or installation angles, and the movably connected device can facilitate the subsequent maintenance or replacement of sensors during operation.

[0060] It should be noted that the sealing plate 330 fixes the two supporting devices together to form an integral structure, and at the same time isolates the flow of the first supporting device 310 and the second supporting device 320, so that the water inlet and water outlet are separated. Therefore, the first supporting device 310 is a supporting device for the water inlet pressure sensor for measuring the water inlet pressure. Similarly, the second supporting device 320 is a supporting device for the water outlet pressure sensor for measuring the water outlet pressure. The two are in a separated state and measured independently.

[0061] When in use, the support assembly 300 is movably connected to the connection assembly 200, and the water inlet and outlet ends of the pressure measuring tube are connected to the water inlet conduit 210 and the water outlet conduit 220 through the connecting pipes, wherein the connecting pipes can be rubber hoses, plastic water pipes, etc., and the present application does not limit the connection method of the connecting pipes and the connection assembly. The support assembly 300 is respectively provided with an inlet pressure sensor and an outlet pressure sensor, and the inlet pressure sensor is used to measure the inlet pressure of the introduced flow medium in the water inlet conduit 210, and the outlet pressure sensor is used to measure the outlet pressure of the introduced flow medium in the water outlet conduit 220, so as to complete the inlet and outlet pressure measurement of the pressure measuring tube. By fixing the pressure sensor on the bracket for pressure calibration, the problem of test data error caused by unstable pressure can be effectively avoided, and the number of times the sensor is disassembled can be reduced, thereby reducing the probability of scrapping the sensor and saving work costs.

[0062] like Figure 1 , Figure 2 and Figure 4 As shown, in a possible implementation, a pressure sensor bracket also includes: two air valves 400, which are respectively arranged on the first supporting device 310 and the second supporting device 320, and are used to discharge residual gas in the medium flow channel during the pressure measurement process; the first supporting device 310 includes: a first connecting member 311, a first conduit 312 and a first supporting member 313; the water inlet conduit 210, the first conduit 312 and the corresponding air valve 400 are connected through the first connecting member 311; the first supporting member 313 is arranged on the first conduit 312, and is used to fix and support the corresponding pressure sensor.

[0063] The two gas valves 400 are respectively arranged on the first supporting device 310 and the second supporting device 320 to independently control the opening and closing of a single gas valve. The two gas valves 400 are respectively used to discharge the residual gas in the pipeline between the water inlet conduit 210 and the first supporting device 310 or the water outlet conduit 220 and the second supporting device 320.

[0064] Specifically, during the pressure measurement process, since the residual gas will affect the stability of the flowing medium and the accuracy of the pressure measurement, the gas valve 400 is used to discharge the residual gas in the medium flow channel. By discharging the gas in time, the reliability of the measurement result can be ensured. The gas valve 400 can be controlled manually or automatically so as to be quickly opened and closed when needed. The specific control method and the gas valve form are not limited here.

[0065] It can be understood that the first connector 311 is used to connect the water inlet conduit 210, the first conduit 312 and the corresponding air valve 400. The first connector 311 can be, for example, a T-shaped three-way pipe or other multi-head pipes that can be fixedly connected, and can also include multiple interfaces and seals to ensure the continuity of the medium flow and prevent leakage, as well as the tight connection and sealing between the components. The first connector 311 is connected to the water inlet conduit 210 to guide the medium into the first conduit 312 through a multi-head guide. The first support member 313 is arranged on the first conduit 312 to fix and support the corresponding inlet pressure sensor. The support member can ensure that the sensor can be stably installed in the specified position and withstand various forces that may be generated during the measurement process.

[0066] During use, the first conduit 312 guides the flowing medium to flow to the pressure sensor through the first support member 313, so that the pressure sensor performs pressure calibration on the flowing medium. Through the air valve 400, the residual gas is discharged before the pressure measurement, which improves the accuracy and reliability of the measurement and reduces the measurement error caused by residual gas or other factors. It should be noted that the air valve and the support member can be independently operated components, which can be flexibly configured or adjusted according to different application scenarios and requirements, so that the components are easy to disassemble and install, and easy to maintain and replace.

[0067] like Figure 1 , Figure 2 and Figure 4 As shown, in a possible implementation, the second supporting device 320 includes: a second connecting member 321, a second conduit 322 and at least two second supporting members 323; the water outlet conduit 220, the second conduit 322 and the corresponding air valve 400 are connected via the second connecting member 321; the at least two second supporting members 323 are arranged on the second conduit 322 according to a preset rule, and are used to fix and support the corresponding pressure sensors, wherein the pressure sensors corresponding to different second supporting members 323 are used to measure pressures of different pressure levels.

[0068] In the embodiment of the present application, the second supporting device 320 includes a second connecting member 321, a second conduit 322 and at least two second supporting members 323, wherein the second connecting member 321 can be, for example, a T-shaped three-way pipe or other multi-head pipes that can be fixedly connected. The second connecting member 321 is used to tightly connect the water outlet conduit 220, the second conduit 322 and the corresponding air valve 400, which can include multiple interfaces and seals to ensure the continuity of the medium flow and prevent leakage. At least two second supporting members 323 are arranged on the second conduit 322 according to a preset rule to fix and support the pressure sensor.

[0069] Specifically, at least two second support members 323 are arranged on the second conduit 322 according to preset rules and can be in a horizontal position of the conduit. For example, they can be set based on various factors such as pressure distribution, measurement requirements, space limitations, etc., so that multiple pressure sensors with different pressure levels can be installed as needed. Each support member can ensure that the sensor can stably and accurately measure the required pressure value.

[0070] When in use, the second support member 323 is used to fix and support the pressure sensor so that it can maintain a stable measurement position, thereby reducing measurement errors caused by movement or vibration of the sensor.

[0071] In other embodiments, at least two second support members 323 can support multiple pressure sensors at the same time, and can monitor different pressure levels of different pressure measuring tubes, thereby improving the flexibility and comprehensiveness of the measurement.

[0072] like Figure 1 and Figure 2 As shown, in a possible implementation, both the first support member 313 and the second support member 323 are provided with a stop valve 340 , and the stop valve 340 is used to control the operating state of the corresponding pressure sensor.

[0073] In this embodiment, the stop valve 340 is used to control the operating state of the corresponding pressure sensor. By opening or closing the stop valve, the medium can be allowed or prevented from flowing through the sensor, thereby realizing the start or stop of the sensor measurement activity. At the same time, when the sensor needs to be maintained, repaired or replaced, the closing of the stop valve can ensure that the medium will not continue to flow through the sensor, providing convenience and safety for maintenance work. It should be noted that the stop valve is usually designed to be fully open or fully closed, but in some cases, the medium flow through the sensor can also be controlled by fine-tuning the opening of the stop valve to achieve further adjustment of the measurement accuracy.

[0074] Specifically, the stop valve 340 is installed on the first support member 313 and the second support member 323, close to the pressure sensor, which can ensure that the medium can be effectively controlled before or after flowing through the sensor, and is also easy to operate and maintain. When selecting and installing the stop valve, a seal with high sealing performance can be selected to ensure that the medium can be completely prevented from leaking in the closed state. In terms of operation, the stop valve can be controlled by, for example, an easily identifiable handle, switch or button, so that the operation and maintenance personnel can complete the switching action.

[0075] It should be noted that the second support member 323 is connected to outlet pressure sensors of different pressure levels. When measuring the outlet pressure, the corresponding stop valve can be opened according to the required pressure level, and other stop valves can be closed to achieve accurate measurement of the outlet pressure.

[0076] During use, by controlling the opening and closing of the stop valve, the flow state of the medium can be controlled, and the measurement error caused by unstable medium flow can be reduced, thereby improving the measurement accuracy and reliability. At the same time, the pressure sensor bracket has higher flexibility. When it is necessary to adjust the measurement range, replace the sensor or perform other maintenance work, the system can be quickly adjusted by operating the stop valve.

[0077] like Figure 1 and Figure 2 As shown, in a possible implementation, a pressure sensor bracket also includes: a first control component 500 and a second control component 600; the first control component 500 is arranged between the water inlet conduit 210 and the first supporting device 310, and is used to control the opening or closing of the medium flow channel between the water inlet conduit 210 and the first supporting device 310; the second control component 600 is arranged between the water outlet conduit 220 and the second supporting device 320, and is used to control the opening or closing of the medium flow channel between the water outlet conduit 220 and the second supporting device 320.

[0078] In this embodiment, the first control assembly 500 is used to control the opening or closing of the medium flow channel between the water inlet conduit 210 and the first support device 310. The first control assembly 500 can control when the medium is allowed to flow from the water inlet conduit 210 and contact the pressure sensor on the first support device 310.

[0079] The first control component 500 may be, for example, a stop valve, a ball valve, etc. The control component may be opened and closed by manual operation, electric control, or pneumatic control, and the present application does not impose any restrictions on this.

[0080] The second control assembly 600 is similar to the first control assembly 500. The second control assembly 600 is disposed between the water outlet conduit 220 and the second support device 320, and is used to control the opening or closing of the medium flow channel between the water outlet conduit 220 and the second support device 320. Similar to the first control assembly 500, the second control assembly 600 may also be a valve or other device capable of controlling the flow of the medium, and the specific control device and control method are not limited in this application.

[0081] During use, different support assemblies 300 can be replaced according to actual needs through the active connection between the first control assembly 500 and the second control assembly 600, so that the pressure sensor bracket is more flexible and expandable in function, which is convenient for subsequent maintenance or replacement of sensors, and more control assemblies and sensors can be added as needed to adapt to different application scenarios and measurement requirements.

[0082] like Figure 1 and Figure 3 As shown, in a possible implementation, a water inlet 230 is provided on the water inlet conduit 210, and a water outlet 240 is provided on the water outlet conduit 220; the water inlet 230 and the water outlet 240 are both provided with an interface 250, and the water inlet 230 and the water outlet 240 are used to be threadedly connected to the two ends of the pressure measuring tube through the corresponding interface 250, so that a medium flow channel is formed among the water inlet conduit 210, the water outlet conduit 220, the first supporting device 310, the second supporting device 320 and the pressure measuring tube.

[0083] The two interfaces 250 are external threaded joints so that the pressure measuring tube can be threadedly connected to the connecting assembly 200 .

[0084] The water inlet 230 is provided on the water inlet conduit 210 and is the entrance for the medium to enter the system, and the water outlet 240 is provided on the water outlet conduit 220 and is the interface corresponding to the outlet of the medium flowing out of the pressure measuring tube. The size and specification of the water inlet 230 and the water outlet 240 can be determined according to the system requirements and the medium characteristics. For example, if the medium is high-pressure water, the size of these two ports needs to be larger to ensure sufficient flow, and the material of the water inlet conduit 210 and the water outlet conduit 220 needs to be able to withstand high pressure.

[0085] Exemplarily, the interface 250 can be a threaded joint or a threaded connector. The interface 250 is arranged on the water inlet 230 and the water outlet 240, and is used for threaded connection with the two ends of the pressure measuring tube, so that a sealed and stable medium flow channel can be formed between the water inlet conduit 210, the water outlet conduit 220, the pressure measuring tube and the support device 300.

[0086] It can be understood that the threaded connection can provide better sealing performance and prevent medium leakage. When the pressure measuring tube needs to be maintained or replaced, the interface 250 and the pressure measuring tube can be easily disassembled. By tightening the interface 250 with appropriate torque, it can be ensured that the connection between the pressure measuring tube and the catheter is firm and reliable, avoiding loosening or falling off during the flow of the medium.

[0087] like Figure 1 and Figure 3 As shown, in a possible implementation, the base 100 includes: a bottom plate 110 and a movable device 120; the bottom ends of the water inlet conduit 210 and the water outlet conduit 220 are fixedly connected to the upper surface of the bottom plate 110, and the movable device 120 is provided on the lower surface of the bottom plate 110, and the movable device 120 is used to drive the bottom plate 110 to drive the pressure sensor bracket to move.

[0088] In the embodiment of the present application, the bottom plate 110 is a stable platform for fixing the bottom ends of the water inlet conduit 210 and the water outlet conduit 220 and supporting the entire pressure sensor bracket. The water inlet conduit 210 and the water outlet conduit 220 can be firmly mounted on the upper surface of the bottom plate 110 by welding, bolting, etc., to ensure that their positions are stable and will not move due to medium flow or other external factors.

[0089] Specifically, the movable device 120 is installed on the lower surface of the base plate 110. Its main function is to drive the base plate 110 and the entire pressure sensor bracket to move. The movable device 120 can be, for example, a mechanical structure such as a slide rail, a roller, a hinge, a rotating shaft, or a driving element such as an electric motor, a hydraulic cylinder, or a pneumatic cylinder. The form of movement can be, for example, translation, rotation, or tilt, etc., depending on the design and application requirements of the movable device. This application does not limit the type and form of the movable device. Through the movable device 120, the position and posture of the bracket can be easily adjusted to adapt to different measurement scenarios and working environments.

[0090] During use, the flexibility of the bracket is increased by the movable device 120, and the base plate 110 is fixed to ensure that the bracket remains stable and reliable when it is moved or adjusted. When it is necessary to clean, repair or replace parts on the bracket, the bracket can be easily moved to a suitable position for operation through the movable device.

[0091] like Figure 3 As shown, in a possible implementation, the first support member 313 and the at least two second support members 323 are both internal threaded joints, so that the pressure sensor is threadedly connected to the first support member 313 or the at least two second support members 323.

[0092] It can be understood that the internal threaded connector is threadedly connected to the external thread on the corresponding pressure sensor. By rotating the pressure sensor, it can be firmly fixed to the corresponding support, thereby ensuring the stability and accuracy of the sensor during the measurement process. Compared with other fixing methods such as welding or gluing, threaded connection is easier to install and disassemble. When replacing or maintaining the pressure sensor, it can be operated more conveniently without disassembling the entire bracket. And due to the standardization and versatility of threaded connection, pressure sensors of different specifications and models can be easily matched and connected with the corresponding support, so that the bracket system can adapt to different measurement requirements and sensor configurations.

[0093] like Figure 1 As shown, in a possible implementation, a pressure sensor bracket also includes: a reinforcing rod 700; the reinforcing rod 700 is arranged perpendicular to the water inlet conduit 210 and the water outlet conduit 220, and the two ends of the reinforcing rod 700 are respectively fixedly connected to the water inlet conduit 210 and the water outlet conduit 220, for fixing the water inlet conduit 210 and the water outlet conduit 220.

[0094] In this embodiment, the reinforcing rod 700 is perpendicular to the water inlet conduit 210 and the water outlet conduit 220, which helps to convert the horizontal forces between the conduits, such as fluid pressure, vibration, etc., into compressive force or tensile force borne by the reinforcing rod 700, thereby dispersing and reducing stress concentration on the conduit itself and other parts of the bracket, thereby improving the stability of the system.

[0095] It should be noted that the two ends of the reinforcing rod 700 are fixedly connected to the water inlet conduit 210 and the water outlet conduit 220 respectively, which can transmit and disperse the force from the water inlet conduit 210 and the water outlet conduit 220, making it a stable supporting structure and preventing the conduit from being displaced or deformed due to factors such as fluid flow, temperature changes or external vibrations.

[0096] It can be understood that the vertical setting of the reinforcing rod 700 and the fixed connection at both ends improve the rigidity of the stent system, maintain the stability of its shape and size, thereby ensuring the accuracy of the pressure sensor measurement, and reducing stress concentration in the catheter and its connection, thereby extending the service life of the catheter and the stent.

[0097] In summary, the embodiment of the present application provides a pressure sensor bracket, including a base 100, a connecting assembly 200 and a supporting assembly 300, one end of the connecting assembly 200 is fixedly connected to the base 100; the connecting assembly includes: an inlet conduit 210 and an outlet conduit 220; the supporting assembly includes: a first supporting device 310, a second supporting device 320 and a sealing plate 330, the bottom end of the first supporting device 310 is movably connected to the top end of the water inlet conduit 210, the bottom end of the second supporting device 320 is movably connected to the top end of the water outlet conduit 220, the supporting assembly 300 is used to support the pressure sensor, and the pressure sensor is used to measure the water inlet pressure of the water inlet conduit 210 or the water outlet pressure of the water outlet conduit 220; the side ends of the first supporting device 310 and the second supporting device 320 are respectively fixedly connected to the two sides of the sealing plate 330. When in use, the pressure sensor is fixed on the corresponding connecting piece to perform pressure calibration, which can effectively avoid the problem of test data errors caused by unstable pressure, reduce the number of times the sensor is disassembled, and thus reduce the probability of sensor scrapping, save work costs, and solve the problem in the prior art that multiple disassembly and installation make the sensor connection threaded part easily damaged, causing sensor damage, and test data errors caused by unstable pressure.
