Description

Technical Field

[0001] The present invention relates to the technical field of pressure gauges, and in particular to a high-precision, low-power pressure gauge. Background Art

[0002] As the application of pressure measurement becomes more and more extensive, the requirements for pressure measuring instruments are also getting higher and higher. At present, elastic and electronic pressure instruments are the most widely used in industrial sites and scientific experiments. However, with the increasing requirements for the degree of measurement automation, electronic pressure gauges have become the mainstream of pressure measurement. Nowadays, the rapid development of informatization has put forward high-precision requirements for electronic pressure gauges. In addition, measuring instruments are now developing towards miniaturization and portability. Dry batteries have become the main power supply method, and the capacity of dry batteries is limited. Therefore, low-power chips are used to reduce battery power supply to achieve high-precision micro-power consumption pressure gauges.

[0003] The internal structure of existing pressure gauges is relatively sophisticated. When they are hit, the pressure gauges themselves do not have strong protective performance, so the impact can easily cause problems such as damage to the pressure gauge structure or loss of accuracy. At the same time, if the impact on the pressure gauge is too strong, the pressure gauge may be damaged, leading to gas or liquid leakage and other problems. This poses a strong safety hazard, and it is necessary to protect the pressure gauge. Summary of the Invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In one embodiment, reference Figures 1-8A high-precision micro-power consumption pressure gauge comprises a test pipe 1 and also comprises: a protective mechanism 2 installed directly above the test pipe 1, wherein the protective mechanism 2 comprises a connecting pipe 21 installed above the test pipe 1, a protective shell 22 fixedly connected to the surface of the connecting pipe 21, a buffer layer 23 fixedly connected to the interior of the protective shell 22, an anti-interference chamber 24 is provided inside the buffer layer 23, and an anti-interference lens 25 is embedded and installed in the connecting pipe 21; a pressure gauge body 3 installed inside the anti-interference chamber 24, the pressure gauge body 3 is connected to the top of the connecting pipe 21; a mounting mechanism 4 arranged between the test pipe 1 and the protective shell 22, the mounting mechanism 4 is used to provide buffering protection for the pressure gauge body 3, and a cleaning mechanism 5 comprises a connecting shell 51 fixed inside the protective shell 22, a driving assembly 52 is arranged inside the connecting shell 51, the driving assembly 52 is connected to one end of the rotating shaft 211, a reciprocating rod 53 is installed at the end of the driving assembly 52, a scraper 54 is installed on the surface of the reciprocating rod 53, and the scraper 54 is in contact with the surface of the anti-interference lens 25.

[0022] By adopting such a solution, under the setting of the protection mechanism 2, the surrounding of the pressure gauge body 3 can be protected, thereby improving the protection effect of the pressure gauge body 3 and further extending the service life of the pressure gauge body 3.

[0023] During specific operation, the protective mechanism 2 is installed above the test pipe 1, and the protective mechanism 2 is used to install the pressure gauge body 3, so as to cover and protect the surface of the pressure gauge body 3. When the protective mechanism 2 is installed, the end of the connecting pipe 21 is installed horizontally with the test pipe 1, and then the pressure gauge body 3 is installed on the top of the connecting pipe 21, so as to monitor the water pressure in the test pipe 1 through the pressure gauge body 3. Under the setting of the protective shell 22 and the buffer layer 23, a semi-enclosed anti-interference chamber 24 can be formed, and then the pressure gauge body 3 can be shielded by the anti-interference chamber 24. With the setting of the protective shell 22, a stronger protective force can be provided for the surface of the pressure gauge body 3 to prevent the impact force from directly exerting pressure on the surface of the pressure gauge body 3 and causing damage. With the setting of the buffer layer 23, electromagnetic interference can be isolated to prevent electromagnetic interference from affecting the use of the pressure gauge body 3. With the setting of the anti-interference chamber 24, a separate environment can be provided for the pressure gauge body 3, so that dust entering will affect the service life of the pressure gauge body 3. The anti-interference lens 25 is embedded and installed inside the connecting pipe 21, which is convenient for the staff to read the pressure gauge body 3, and the anti-interference lens 25 also has an anti-interference effect.

[0024] In one embodiment, reference Figure 2 、 Figure 3 and Figure 4The mounting mechanism 4 includes a threaded barrel 41 arranged between the test pipe 1 and the protective shell 22. Both ends of the threaded barrel 41 are threadedly connected with threaded rods 42. The threaded rod 42 near the top of the threaded barrel 41 is fixedly connected to the bottom of the protective shell 22. The threaded rod 42 near the bottom of the threaded barrel 41 is fixedly connected with an upper clamping plate 43. A lower clamping plate 44 is provided at the bottom of the upper clamping plate 43. The upper clamping plate 43 and the lower clamping plate 44 are both installed on the surface of the test pipe 1. Buffer gaskets 45 are fixedly connected to the inside of the upper clamping plate 43 and the lower clamping plate 44. The number of buffer gaskets 45 is symmetrically arranged in two groups.

[0025] With such a solution, under the setting of the installation mechanism 4, it can be installed on the surface of the test pipe 1, thereby further enhancing the stability effect of the protection mechanism 2. At the same time, it can absorb the vibration generated by the water pressure, preventing the water pressure vibration force from being directly applied to the inside of the pressure gauge body 3 to cause damage to internal parts, thereby further extending the service life of the pressure gauge body 3.

[0026] During specific operation, the two threaded rods 42 can be respectively threaded up and down inside the threaded barrel 41 by setting the threaded barrel 41, and then can be respectively fixed on the surface of the protective shell 22 and the upper clamping plate 43 by setting the threaded rod 42, and then the upper clamping plate 43 is covered on the upper surface of the test pipe 1, and the lower clamping plate 44 is covered on the lower surface of the test pipe 1, and then the upper clamping plate 43 and the lower clamping plate 44 are respectively connected by bolts, so that the upper clamping plate 43 and the lower clamping plate 44 are fixed on the surface of the test pipe 1, so as to ensure the stability of the pressure gauge body 3 inside the protective shell 22, and the upper and lower threaded rods 42 can be displaced synchronously at the same time when the threaded barrel 41 is rotated, so as to control the protection The distance between the shell 22 and the upper clamping plate 43 is increased to increase the height difference between the pressure gauge body 3 and the test pipe 1, so that the staff can read the readings at eye level, and by setting the buffer gasket 45 between the upper clamping plate 43 and the lower clamping plate 44, the buffer gasket 45 can be squeezed on the surface of the test pipe 1. The material of the buffer gasket 45 is plastic, so the friction between the upper clamping plate 43 and the lower clamping plate 44 and the test pipe 1 can be increased to prevent sliding. When the water pressure inside the test pipe 1 vibrates, the buffer gasket 45 can absorb and damp the vibration force, thereby reducing the influence of water pressure on the pressure gauge body 3, thereby extending the service life of the pressure gauge body 3.

[0027] In one embodiment, reference Figure 6 、 Figure 7 and Figure 8The interior of the connecting pipe 21 is rotatably connected to a rotating shaft 211 through a bearing, and a turbine 212 is fixedly connected to the surface of the rotating shaft 211. The turbine 212 is located inside the connecting pipe 21 and fits in place. The interior of the protective shell 22 is fixedly connected to a cleaning mechanism 5, which is fixedly connected to one end of the rotating shaft 211. The cleaning mechanism 5 is used to clean the surface of the anti-interference lens 25. The cleaning mechanism 5 includes a connecting shell 51 fixed to the interior of the protective shell 22. A driving assembly 52 is provided inside the connecting shell 51. The driving assembly 52 is connected to one end of the rotating shaft 211, and a reciprocating rod 53 is installed at the end of the driving assembly 52. A scraper strip 54 is installed on the surface of the reciprocating rod 53, and the scraper strip 54 is in contact with the surface of the anti-interference lens 25. The driving assembly 52 includes a main gear 521 fixed to the end of the rotating shaft 211, and the surface of the main gear 521 is meshed with a secondary gear 522. The secondary gear 522 is rotatably connected to the interior of the connecting shell 51 through a rotating shaft. The surface of the secondary gear 522 is fixedly connected to a linkage rod 523, and the surface of the linkage rod 523 is fixedly connected to a shift rod 524. The surface of the shift rod 524 is fixedly connected to a transmission rod 525. The transmission rod 525 is rotatably connected to the interior of the connecting shell 51 through a bearing, and the end of the transmission rod 525 is fixed to the side wall of the reciprocating rod 53.

[0028] By adopting such a solution, the water pressure inside the test pipe 1 can be used to drive the rotating shaft 211 to rotate the fixed turbine 212. When the turbine 212 drives the rotating shaft 211 to rotate, power output can be provided for the cleaning mechanism 5. Driven by the cleaning mechanism 5, the surface of the anti-interference lens 25 can be reciprocated to clean dust, preventing dust from adhering to the surface of the anti-interference lens 25 and affecting the later readings of the pressure gauge body 3 by the staff.

[0029] During specific operation, when the water pressure inside the test pipe 1 drives the rotation of the turbine 212 inside the rotating shaft 211, the rotating shaft 211 will drive the cleaning mechanism 5, and the driving assembly 52 is protected by the connecting shell 51. When the driving assembly 52 is fixed to the rotating shaft 211, the reciprocating rod 53 fixed to the driving assembly 52 can be driven to swing back and forth. Since the scraper 54 is attached to the surface of the anti-interference lens 25, the reciprocating rod 53 drives the scraper 54 to swing back and forth to clean the dust adhered to the anti-interference lens 25. The whole process does not require manual operation. The change of water pressure is used as the power source to achieve the cleaning of the surface of the anti-interference lens 25, and the pressure gauge body 3 inside the protective shell 22 is further protected, preventing dust from adhering to the anti-interference lens 25 and covering it, causing inconvenience in reading, and also avoiding damage caused by manual cleaning. When the driving component 52 is working, the main gear 521 is fixedly connected to the rotating shaft 211, so that the rotating shaft 211 drives the main gear 521 to rotate. Since the secondary gear 522 is engaged with the surface of the main gear 521, the secondary gear 522 is synchronously driven to rotate. When the secondary gear 522 rotates, the linkage rod 523 on the surface is synchronously rotated, and the linkage rod 523 drives the shift rod 524 to rotate. Since the end of the shift rod 524 is connected to the shell 51 through the rotating shaft, the shift rod 524 will rotate, and the transmission rod 525 is synchronously rotated when the shift rod 524 rotates. Since the reciprocating rod 53 is installed on the surface of the transmission rod 525, the reciprocating rod 53 is synchronously driven to swing back and forth left and right.

[0030] In one embodiment, reference Figure 8 A dovetail groove 55 is provided inside the reciprocating rod 53 , and a dovetail block 56 is fixedly connected to one side of the scraper strip 54 , and the dovetail block 56 slides inside the dovetail groove 55 .

[0031] By adopting such a solution, the reciprocating rod 53 and the scraper 54 can be quickly disassembled through the setting of the dovetail groove 55 and the dovetail block 56, so that the scraper 54 can be replaced when the cleaning effect of the anti-interference lens 25 surface is not good, thereby improving the service life of the equipment.

[0032] During specific operation, when the dovetail groove 55 is opened, the dovetail block 56 can be slid inside the dovetail groove 55. Since the dovetail block 56 is fixed to the side wall of the scraper 54, when the dovetail block 56 is separated from the dovetail groove 55, the reciprocating rod 53 and the scraper 54 can be quickly disassembled, so that the scraper 54 can be replaced when the cleaning effect of the anti-interference lens 25 surface is not good, thereby improving the service life of the equipment.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
