[0002] A differential pressure gauge is an instrument used to measure pressure differences.

[0032] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0033] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0034] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0035] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0036] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0037] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0038] As can be seen from the records of the background technology, the differential pressure gauge can determine the height of the liquid through the pressure difference of the liquid, and the control center of the differential pressure gauge can display information such as the liquid level height and the pressure difference, so that the user can better understand the pressure conditions in the liquid storage tank.

[0039] Since the control center of the differential pressure gauge has the function of displaying information such as liquid level height and pressure difference, the differential pressure gauge includes multiple functional components. These functional components usually need to be assembled. After the functional components are equipped, protective devices can be set to better protect the functional components of the differential pressure gauge.

[0040] In the related art, a mechanical instrument is usually used to display the pressure in the liquid storage tank. This method is not only inconvenient for users to view the specific pressure in the liquid storage tank, but also easy for users to misread the pressure.

[0041] That is, the differential pressure gauge disclosed in the present invention can display pressure information in a numerical manner, which not only allows users to better view the specific pressure, but also is not easy to misread. However, this method requires the cooperation of multiple functional components, so it is necessary to design a corresponding protection device for the differential pressure gauge control center to carry the differential pressure gauge control center and protect the various functional components of the differential pressure gauge control center.

[0042] Please refer to Figure 1-5 , Figure 1 shows a partial schematic diagram of the interior of a housing for protecting a differential pressure gauge control center according to the present disclosure, Figure 2 A schematic diagram showing the position of the side enclosure frame and the fixing device of the housing for protecting the differential pressure gauge control center according to the present disclosure is shown. Figure 3 A schematic diagram showing a fixing plate of a fixing differential pressure gauge control center according to the present disclosure is shown. Figure 4 A schematic diagram of a cover plate for protecting a housing of a differential pressure gauge control center disclosed in the present invention is shown. Figure 5 It can be understood as a side view of the housing used to protect the differential pressure gauge control center of the present disclosure. Figure 1-5 It can be seen that the differential pressure gauge control center may include a battery 110, detection components and a control chip. The battery 110 may be used to provide power for the detection components and the control chip. The housing 10 used in the differential pressure gauge control center may include:

[0043] A fixing plate 120, a side enclosure frame 130 and a cover plate 140 adapted to the side enclosure frame 130;

[0044] The fixing plate 120, the side enclosure frame 130 and the cover plate 140 are combined to form a accommodating cavity, in which a fixing device 150 is arranged, and the detection components are arranged inside the fixing device 150. The fixing device 150 is provided with a plurality of through holes, wherein the plurality of through holes at least include: an air intake hole for air intake, and a circuit hole for transmitting the detection signal to the control core.

[0045] It should be understood that the fixing device 150 can be detachably connected to the side enclosure 130 or the fixing plate 120, that is, how to stably arrange the fixing device 150 in the accommodating cavity can be determined according to actual conditions. For example, the fixing device 150 can be connected to the side enclosure 130 by bolt connection.

[0046] The storage battery 110 may be disposed outside the fixing device 150 , and the control chip is also disposed outside the fixing device 150 ; and the control chip and the storage battery 110 are also disposed inside the accommodation cavity.

[0047] That is, in the present disclosure, two protection spaces can be formed, one protection space (the first protection space) is a accommodating cavity formed by the fixing plate, the side surrounding frame and the cover plate, and the other protection space is a protection space (the second protection space) inside the fixing device; the battery and the control chip are arranged between the first protection space and the second protection space, and the detection components are arranged inside the second protection space.

[0048] It should be understood that the housing is provided with through holes that match the multiple through holes opened by the fixing device, so that it is convenient for air intake and pressure relief ( Figure 2 The large round opening 201 in the figure can be understood as an air inlet, and Figure 2 The small round opening 202 in the middle can be understood as a pressure relief hole. Figure 1 The circular opening 203 in the figure can be understood as a through hole for threading).

[0049] The cover plate 140 may be provided with at least two openings, which may include a first opening 141 and a second opening 142. The first opening 141 may be used to set a display screen, which may be used to display the detection information of the differential pressure gauge and / or the status information of the differential pressure gauge. The second opening 142 may be used to set function keys of the differential pressure gauge, wherein the control chip may be used to generate status information.

[0050] It should be understood that the cover plate 140 is provided with at least two openings, so that information display and adjustment operations can be performed on the same surface, which is convenient for user operation and observation.

[0051] As an example, since a fixing device 150 is provided, and the detection components are provided inside the fixing device 150, and the battery 110 is provided outside the fixing device 150, the detection components are separated from the battery 110, thereby preventing the heat generated by the battery 110 during use from causing detection errors of the detection components, and preventing the heat generated by the battery 110 during use from affecting the service life of the detection components.

[0052] At the same time, since the volume of the detection components is usually much smaller than that of the battery 110, this method can also reduce the volume of the fixing device 150. Moreover, arranging the battery 110 outside the fixing device can also make the battery 110 dissipate heat better, thereby avoiding excessive heat of the battery 110.

[0053] As an example, the fixing device 150 is detachably arranged in the accommodating cavity, the side enclosure frame 130 and the cover plate 140 can be detachably connected, and the fixing plate 120 and the side enclosure frame 130 can also be detachably connected, so that the shell can be assembled on site at the actual application site, so that the shell can be easily transported. Of course, the fixing device 150 is detachably arranged in the accommodating cavity, and the functional components can be arranged in the fixing device 150. In this way, during transportation, the fixing device 150 can be removed from the accommodating cavity, and the fixing device 150 can be used to perform separate protection operations on the detection components, thereby avoiding damage to the detection components as much as possible.

[0054] Furthermore, since the fixing device 150 is detachably connected to the accommodating cavity, the side enclosure frame 130 and the cover plate 140 can also be detachably connected, so that it is convenient to inspect and replace the detection components disposed in the fixing device 150 .

[0055] Furthermore, since the battery 110 is arranged in the accommodating cavity and the battery 110 is arranged outside the fixing device 150, and the replacement frequency of the battery 110 is usually higher than the replacement frequency of the detection components, such a setting method can not only protect the battery 110, but also facilitate the replacement of the battery 110.

[0056] In the present disclosure, by setting the detection component in a fixing device, which is also set in a shell, the detection component is doubly protected, which not only protects the detection component from being affected by the external environment, but also reduces the impact of battery heating on the detection component, thereby making the working environment of the detection component better, and thus achieving better and more accurate liquid pressure detection.

[0057] It should be understood that the detection information of the differential pressure gauge may at least include the pressure information of the liquid tank to be tested, and the status information of the differential pressure gauge may at least include basic information such as time and date. By displaying the detection information and / or status information of the differential pressure gauge, the differential pressure gauge is made more intelligent, so that the user can more conveniently understand the detection status and status of the differential pressure gauge.

[0058] Furthermore, the cover plate of the shell of the present invention is also provided with at least two openings, and the at least two openings include a first opening and a second opening. The first opening is used to set a display screen, and the display screen is used to display the detection information of the above-mentioned differential pressure gauge and / or the status information of the above-mentioned differential pressure gauge. In this way, the shell of the present invention can be suitable for differential pressure gauges with a higher level of intelligence.

[0059] In order to facilitate understanding of the functional devices provided by the first opening and the second opening, please continue to refer to Figure 5 , Figure 5 It can be understood as a schematic diagram of the upper cover plate provided by the possible implementation mode of the present disclosure, from Figure 5 It can be seen that the first opening 141 can be provided with a display screen so that the differential pressure gauge control center can display detection information, and the second opening 142 can be provided with function keys to adjust the display content.

[0060] Further, by Figure 2 It can be seen that the differential pressure gauge control center can also include an alarm device 210 and a transmission antenna 220, so that the functions of the differential pressure gauge control center can be more complete. For example, the alarm device 210 can be used to alarm when an abnormality is detected, and the abnormal information can be transmitted through the transmission antenna 220.

[0061] In some implementations, the fixing plate, the side surround frame, and the cover plate may all be made of high-strength materials such as metal or alloy, which can improve the durability of the entire housing.

[0062] In some embodiments, it can be combined with Figure 1 and Figure 2 The air intake hole for air intake and the pressure relief hole for installing the pressure relief valve can be opened on the first frame 131 of the side surround frame 130, and the multiple through holes opened by the fixing device 150 can correspond to the through holes on the first frame 131. In this way, the space occupied by the fixing device 150 can be saved to a certain extent.

[0063] In some embodiments, the control chip may be disposed on the back of the cover.

[0064] As an example, the control chip is arranged on the back of the cover plate, so that the connection lines between the display screen and the buttons and the control chip can be shortened, thereby avoiding connection failures caused by the connection line process, and at the same time, it can also save the connection lines required in the manufacturing process.

[0065] For ease of understanding, you can combine Figure 6 To explain, Figure 6 It can be understood as an exemplary schematic diagram of a cover plate for protecting the housing of a differential pressure gauge control center. Figure 6The recess indicated by the number 143 in the figure can be understood as the setting position of the control chip.

[0066] In some embodiments, the back plate of the cover plate may be provided with a snap-fit ​​piece, and the control chip may be fixed to the back of the cover plate through the snap-fit ​​piece.

[0067] That is, the method of fixing the control chip on the back of the cover plate by snapping can facilitate the disassembly of the control chip, so that the control chip can be better inspected and repaired.

[0068] It should be understood that placing the control chip on the back of the cover plate can also prevent the control chip from being squeezed, thereby extending the service life of the control chip. The specific number and specific fastening method of the fastening parts can be limited according to actual conditions.

[0069] In some embodiments, the control chip may also be disposed on the first surface of the fixing device.

[0070] As an example, the first surface of the fixing device and the upper cover plate may be relatively parallel, so that the connection lines between the control chip and the display screen and the buttons can be shorter.

[0071] In some embodiments, the battery is disposed on the second side of the fixture; and the first side of the fixture is adjacent to the second side of the fixture.

[0072] As an example, the battery is arranged on the second side of the fixing device, which can further save the space required for the housing and also better achieve stable fixation of the battery.

[0073] In some embodiments, a plurality of through holes are provided on the first surface and the third surface of the fixing device, the third surface abuts against the first surface of the containing frame, a through hole is provided on the first surface of the containing frame, the through holes provided on the first surface of the containing frame are adapted to the through holes provided on the first surface of the fixing device, and the first surface of the fixing device is adjacent to the third surface of the fixing device.

[0074] As an example, it can also be understood that the second surface and the third surface of the fixing device are opposite to each other. In this way, the volume required for installing the storage battery and the fixing device can be saved, thereby making the overall volume of the housing smaller.

[0075] To facilitate understanding of the various aspects of the fixture, you can combine Figure 7 To explain, Figure 7 It can be understood as a schematic diagram of the fixing device provided by the exemplary embodiment of the present invention, Figure 7 It can be seen that the surface indicated by number 151 can be understood as the first surface, the surface indicated by number 152 can be understood as the second surface, and the surface indicated by number 153 can be understood as the third surface.

[0076] In some embodiments, the housing further comprises a power supply protection sleeve, and the power supply protection sleeve is used to protect the battery;

[0077] The power supply protection cover is in the shape of a rectangular body, and the rectangular body is connected to the back plate of the containing frame through bolts, and the rectangular body includes at least two heat dissipation through holes.

[0078] As an example, the material of the rectangular body can be a material with strong heat dissipation capability and certain strength, such as metal, alloy, plastic, etc.

[0079] As an example, providing a power supply protection cover for the battery can better protect the battery, so that the battery can be prevented from being damaged during transportation.

[0080] In some embodiments, the control chip may also be fixed on the first surface of the power protection cover.

[0081] As an example, the control chip is fixed on the first side of the power protection cover. In this way, the connection lines between the control chip and the display screen and the buttons can be shorter. At the same time, since the size of the power protection cover is usually large, it is also convenient to fix the control chip on the first side of the power protection cover.

[0082] For ease of understanding, you can combine Figure 8 To explain, Figure 8 It can be understood as a front view of the power supply protective cover provided by the exemplary embodiment. Figure 8 It can be seen that the power protection cover 801 may include a heat dissipation through hole 801, and the area indicated by the number 802 can be understood as the setting position of the control chip.

[0083] It should be understood that heat dissipation holes may also be provided on other surfaces of the power supply protection cover to achieve better heat dissipation.

[0084] In some embodiments, the shell further includes at least three fixing bolts, and any one of the fixing bolts connects the back plate, the side surround frame and the cover plate.

[0085] As an example, by providing fixing bolts, the fixing plate, the side surrounding frame and the cover plate can be integrally connected, so that the shell formed by the back plate, the side surrounding frame and the cover plate can be more stable.

[0086] As an example, through holes are provided on the edges of the fixing plate, the side surrounding frame and the cover plate, and bolts can be used through the through holes to integrally connect the fixing plate, the side surrounding frame and the cover plate.

[0087] It should be understood that the specific location of the through hole can be limited according to actual conditions, and the actual location of the through hole is not limited here.

[0088] In some embodiments, the present disclosure further provides a differential pressure gauge, which includes the above-mentioned shell, battery, detection element and control chip, and the shell is used to set the above-mentioned battery, the above-mentioned detection element and the above-mentioned control chip.
