Description

Technical Field

[0001] The utility model relates to the technical field of pressure detectors, in particular to a water hammer prevention pressure detector. Background Art

[0002] An intelligent pressure acquisition terminal, or pressure detector, is a commonly used pressure detector in industrial practice. It is widely used in various industrial automation environments, water conservancy and hydropower projects, transportation and construction equipment, production automation systems, aerospace technology, shipbuilding technology, and pipelines. In the water conservancy and hydropower sector, intelligent water pressure detectors typically use single-crystal silicon sensors as their core. Their operating principle is that the pressure of the measured water directly or indirectly acts on the sensor's diaphragm, causing a micro-displacement proportional to the water pressure, which in turn changes the sensor's resistance. This change is detected by electronic circuitry and converted into a standard measurement signal corresponding to the pressure, achieving precise water pressure measurement.

[0003] However, when monitoring water pressure, there may be unstable factors in the water environment that affect the measurement of pressure values, such as water hammer, which will cause fluctuations in the water and hit the sensor diaphragm, resulting in inaccurate water pressure measurement.

[0004] Therefore, the utility model provides a water hammer pressure detector to solve the above problems. Utility Model Content

[0005] The utility model provides a water hammer-proof pressure detector. A counteracting protective cover is movably installed on a bent sensing antenna. When the detector monitors water pressure in an environment with water hammer, buffer components movably installed on the surrounding walls of the counteracting protective cover can be used to reduce shock and counteract the water hammer effect, thereby avoiding the water hammer effect from directly impacting the bent sensing antenna, ensuring the stability and effectiveness of water pressure monitoring, improving the accuracy of water pressure measurement, and solving the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, the present invention provides a water hammer pressure detector, comprising: a meter body 1, provided with a display dial 2 for displaying pressure values; a nut assembly 3 at one end of the meter body 1 to facilitate threaded installation 8 of the detector; and a flexural sensing antenna 4 at the other end. When sensing water pressure, the flexural sensing antenna 4 deforms, allowing the internal sensor to detect the corresponding pressure value, thereby achieving a pressure measurement function. A compensating cover 5 is movably mounted on the flexural sensing antenna 4. When the detector monitors water pressure in an environment subject to water hammer, buffer assemblies movably mounted on the surrounding walls of the compensating cover 5 can reduce shock and offset the water hammer effect, ensuring the stability and effectiveness of water pressure monitoring.

[0024] The details are as follows: first, the offsetting cover 5 is set to a cylindrical structure, and the offsetting cover 5 is nested and installed on the bending sensing antenna 4 to ensure that the bending sensing antenna 4 can be fully surrounded, so that the water flow can only be buffered from the side and top of the offsetting cover 5, and then stably enter the interior to monitor the bending sensing antenna 4 to ensure stability.

[0025] like Figure 2 、 Figure 3 As shown, a positioning seat 6 is provided above the meter body 1, and a connecting post 7 is provided at one end of the offset protective cover 5. Threads 8 are provided on the outer wall of the connecting post 7 and the positioning seat 6. The connecting post 7 is movably mounted on the positioning seat 6 via the threads 8. In stable water environments, measurements can be taken without installing the offset protective cover 5. In harsh water environments, the offset protective cover 5 can be rotated and installed on the positioning seat 6 before pressure measurement. At the same time, the installation method of the threaded connection 8 helps to ensure sealing stability.

[0026] like Figure 3 As shown, the buffer assembly includes a plurality of first side buffer plates 9 symmetrically arranged on the side walls of the offsetting protective cover 5, and a second top buffer plate 10 arranged on the top wall of the offsetting protective cover 5. The first side buffer plates 9 and the second top buffer plates 10 are elastically mounted on the offsetting protective cover 5. By performing side and top buffering on the water hammer, an all-round stabilization effect on the water hammer is achieved. At the same time, when the water hammer hits the first side buffer plate 9 or the second top buffer plate 10, the reaction force of the spring 14 will cause a recoil on the water hammer effect, thereby achieving a buffering effect of part of the impact force generated in the initial stage, which is conducive to improving stability. Subsequent water ripples enter the two-stage buffer flow channels respectively to dissipate energy and stabilize the flow, thereby achieving a stable water flow effect and improving the monitoring stability and effectiveness of the bending sensing antenna 4.

[0027] Among them, the buffering in the initial stage is achieved by the elastic rods 13 set at both ends of the two second-stage side buffer flow channels 12. The two elastic rods 13 are connected to the inner wall of the offset cover 5 through springs 14. When the water hammer initially impacts, the entire first side buffer plate 9 will be elastically deformed to offset the impact force. This stage can greatly buffer the water hammer, and with the reset action of the spring 14, the water hammer effect will be greatly reduced.

[0028] Similarly, the water hammer effect generated on the top of the offset cover 5 is also offset in the same way, by providing elastic rods 13 at both ends of the two second-stage top buffer flow channels 16, and the two elastic rods 13 are connected to the inner top wall of the offset cover 5 through springs 14.

[0029] In the second stage, a large number of water ripples will be generated after the water hammer offsets the impact energy. At this time, a first-level side buffer flow channel 11 is provided inside the first side buffer plate 9, and multiple second-level side buffer flow channels 12 are provided at one end of the first side buffer plate 9 for graded buffering. The water ripples enter the first-level side buffer flow channel 11 and the second-level side buffer flow channel 12 respectively to achieve sufficient energy dissipation and flow stabilization effects.

[0030] Similarly, the water ripples generated on the top of the protective cover 5 are offset in the same way, by setting a first-level top buffer channel 15 inside the second top buffer plate 10, and a plurality of second-level top buffer channels 16 are set at one end of the second top buffer plate 10 for graded buffering.

[0031] Further, such as Figure 3 As shown, a plurality of first-stage side buffer baffles 17 are provided in the first-stage side buffer channel 11, and the plurality of first-stage side buffer baffles 17 are arranged in an "S"-shaped structure. When a large number of water ripples enter the first-stage side buffer baffles 17, due to the close arrangement of the "S"-shaped structure, the shape impact of the water ripples will be greatly and comprehensively buffered. The water ripples will be reflected when passing through each first-stage side buffer baffle 17 of the "S"-shaped structure. The reflections are continuously accumulated and superimposed, and continuously offset each other, thereby achieving a buffering effect; and a plurality of second-stage side buffer baffles 18 are provided in the second-stage side buffer channel 12, and the plurality of second-stage side buffer baffles 18 are arranged in a "V"-shaped structure, so as to buffer the remaining small water ripples or micro water ripples, and finally the water flow entering the inside of the offsetting cover 5 is a calm water flow.

[0032] Similarly, a plurality of first-stage top buffer baffles 19 are provided in the second-stage top buffer channel 16, and the plurality of first-stage top buffer baffles 19 are arranged in an "S"-shaped structure. When a large number of water ripples enter the first-stage side buffer baffle 17, due to the close arrangement of the "S"-shaped structure, the shape impact of the water ripples will be greatly and comprehensively buffered. The water ripples will be reflected after passing through each first-stage side buffer baffle 17 of the "S"-shaped structure. The reflections are continuously accumulated and superimposed, and continuously offset each other, thereby achieving a buffering effect; a plurality of second-stage top buffer baffles 20 are provided in the second-stage top buffer channel 16, and the plurality of second-stage top buffer baffles 20 are arranged in a "V"-shaped structure, so as to buffer the remaining small water ripples or micro water ripples, and finally make the water flow entering the inside of the offsetting protective cover 5 a calm water flow.

[0033] In summary, the utility model provides a water hammer-proof pressure detector, in which a counteracting protective cover 5 is movably installed on the bent sensing antenna 4. When the detector monitors water pressure in an environment with water hammer, the buffer components movably installed on the four walls of the counteracting protective cover 5 can be used to reduce shock and offset the water hammer effect, thereby avoiding the water hammer effect from directly hitting the bent sensing antenna 4, ensuring the stability and effectiveness of water pressure monitoring, and improving the accuracy of water pressure measurement.
