Description

Technical Field

[0001] The utility model relates to the field of gas monitoring, in particular to a gas multi-dimensional data collector with the function of detecting cabinet doors or manhole covers. Background Art

[0002] At present, data collectors are mostly installed in gas pressure regulating cabinets or pressure regulating wells. The data collectors are used to monitor the relevant working conditions in the pressure regulating cabinets or pressure regulating wells in real time. When an abnormality occurs, the sensor components of the data collector send the detected data to the control unit. The control unit processes the received information and then transmits it to the communication module, which reports it to the server through the communication module. Staff can remotely access the server to know the working status of the pressure regulating cabinet or pressure regulating well. For example, the utility model patent with the authorization announcement number CN216143572U discloses a data collector installed in a pressure regulating box.

[0003] However, the current data collectors do not have the function of detecting the cabinet doors of pressure regulating cabinets or the manhole covers of pressure regulating wells. If the cabinet doors of pressure regulating cabinets or the manhole covers of pressure regulating wells are abnormally opened or not closed, the equipment in the pressure regulating cabinets or pressure regulating wells will be exposed, posing risks such as leakage, short circuit and safety hazards. It is not easy to immediately detect that the cabinet door of the pressure regulating cabinet or the manhole cover of the pressure regulating well is opened. It can only be discovered when the inspection personnel conduct inspections, which is very unfavorable for the safety management of the pressure regulating cabinet or pressure regulating well. Summary of the Utility Model

[0004] The utility model aims to provide a gas multi-dimensional data collector with the function of detecting cabinet doors or manhole covers to solve the problem that the opening and closing states of the current cabinet doors or manhole covers cannot be detected.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A gas multi-dimensional data collector with the function of detecting cabinet doors or manhole covers, including a housing. Inside the housing, there is a control unit and a communication module. The communication module is electrically connected to the control unit. The communication module includes an antenna located on the housing. A displacement switch electrically connected to the control unit is provided on the outer side of the housing.

[0006] The principle and advantages of this solution are as follows: The gas multi-dimensional data collector in this application is used to monitor the working environment, relevant working parameters, and data in the pressure regulating cabinet or pressure regulating well. Since the data collector in the prior art also has a control unit and a communication module, the control unit and communication module of the gas multi-dimensional data collector in this application are of the prior art. The improvement of the data collector in this application lies in the installation of a displacement switch on the data collector. A displacement switch is a sensor device used to detect the displacement of an object. The data collector in this application is installed in the pressure regulating cabinet or pressure regulating well to detect whether the cabinet door or manhole cover is closed. When the cabinet door of the pressure regulating cabinet or the manhole cover of the pressure regulating well is not closed, the displacement switch detects that the cabinet door or manhole cover is not closed, and the displacement switch transmits this information to the control unit. The information is then transmitted to the network server through the communication module. The staff can remotely access the server through a computer, so as to be able to timely know that the cabinet door or manhole cover is not closed, and the staff can reach the site in time to close the cabinet door or manhole cover.

[0007] Preferably, as an improvement, the displacement switch is a sliding displacement switch. The sliding displacement switch has a simple structure. When the cabinet door or manhole cover is closed, the cabinet door or manhole cover squeezes the sliding displacement switch, and the sliding displacement switch detects that the cabinet door or manhole cover is closed. When the cabinet door or manhole cover is opened, the cabinet door or manhole cover no longer squeezes the sliding displacement switch, and the sliding displacement switch detects that the cabinet door or manhole cover is opened.

[0008] Preferably, as an improvement, the displacement switch is provided with a plurality of first fixing holes, and the housing is provided with second fixing holes. The first fixing holes and the second fixing holes are connected by fixing members. Thus, by connecting the fixing members to the first fixing holes and the second fixing holes, the displacement switch is fixedly installed on the housing.

[0009] Preferably, as an improvement, the fixing member is a screw or a bolt.

[0010] Preferably, as an improvement, the second fixing holes have two rows, each row of the second fixing holes has a plurality of them, the two rows of second fixing holes are arranged in parallel, and the plurality of second fixing holes in each row are arranged in sequence.

[0011] If the installation position of the displacement switch on the housing is fixed and cannot be adjusted, when the data collector is installed in different pressure regulating cabinets or wells, due to the different sizes of different pressure regulating cabinets or wells, or there is a certain error in the installation position when the installer installs the data collector in the pressure regulating cabinet or well, it is impossible to ensure that the installation positions of the data collectors in each pressure regulating cabinet or well are exactly the same. Then, due to the inaccurate installation position of the data collector, the displacement switch may not be able to normally abut against the closed cabinet door or manhole cover for detection. In addition, if displacement switches of different sizes are installed on the data collector, due to the different volumes of the displacement switches, if the installation position of the displacement switch cannot be adjusted, it may also cause the displacement switch to not be able to normally abut against the closed cabinet door or manhole cover for detection.

[0012] Therefore, there are multiple second fixing holes in this application. By connecting the first fixing holes on the displacement switch to different second fixing holes, the installation position of the displacement switch on the housing in the arrangement direction of the second fixing holes can be made non-fixed. The displacement switch can be installed at different positions on the housing according to the actual situation, so that the displacement switch can normally abut against the closed cabinet door or manhole cover.

[0013] Preferably, as an improvement, the row spacing between two rows of second fixing holes is adjustable.

[0014] If displacement switches of different sizes are installed on the data collector (for example, different batches and different sizes of displacement switches are installed on different data collectors when the data collectors leave the factory, or if the displacement switch is damaged during later use, displacement switches of different sizes may be installed for replacement), then due to the different sizes of the displacement switches, the distance between the two first fixing holes on the displacement switch is different, and the row spacing between two rows of second fixing holes is adjustable, so as to be adapted to displacement switches with different first fixing hole spacings, and displacement switches of different sizes can be installed on the data collector.

[0015] Preferably, as an improvement, a sliding piece is slidably connected to the housing, and one row of second fixing holes is located on the sliding piece. At this time, by laterally sliding this sliding piece, the distance between the two rows of second fixing holes can be adjusted;

[0016] Or, two sliding pieces are slidably connected to the housing, and two rows of second fixing holes are respectively located on the two sliding pieces. At this time, by sliding the two sliding pieces, the distance between the two rows of second fixing holes can also be adjusted.

[0017] Preferably, as an improvement, a sliding cavity is provided on the housing, the sliding piece is located in the sliding cavity, the width of the sliding cavity is greater than the width of the sliding piece, and an insertion opening communicating with the sliding cavity is provided on the housing, and the insertion opening is detachably connected with a plugging cover.

[0018] Therefore, the width of the sliding cavity is greater than the width of the sliding piece, so that the sliding piece can slide horizontally in the sliding cavity, thus realizing the sliding of the sliding piece. The insertion port is used as the entrance for the sliding piece to insert into the sliding cavity. After the sliding piece is inserted into the sliding cavity, the sealing cover is placed at the insertion port to seal the insertion port, so that the sliding piece will not fall out from the insertion port.

[0019] Preferably, as an improvement, the housing is provided with a Bluetooth module and a positioning module, and both the Bluetooth module and the positioning module are electrically connected to the control unit.

[0020] The setting of the Bluetooth module enables this multi-dimensional data collector to have the function of Bluetooth connection. In this way, for the on-site inspection staff, the staff can use a handheld terminal to connect to this gas multi-dimensional data collector through Bluetooth connection. The gas multi-dimensional data collector transmits data and other information to the handheld terminal through Bluetooth transmission, and the handheld terminal displays the data collected by the gas multi-dimensional data collector, so as to facilitate viewing the equipment operation logs and operation parameters in the pressure regulating cabinet or pressure regulating well.

[0021] The positioning module is used to locate the position of this gas multi-dimensional data collector. In this way, when the gas multi-dimensional data collector detects abnormal operation of the equipment in the pressure regulating well or pressure regulating cabinet, while uploading the abnormal data to the server, it can also upload the geographical location, so as to facilitate remote personnel to know the location of the pressure regulating well or pressure regulating cabinet.

[0022] Preferably, as an improvement, the housing is provided with a laser methane sensor and a pressure sensor probe, and both the laser methane sensor and the pressure sensor probe are electrically connected to the control unit.

[0023] The laser methane sensor is used to detect the methane concentration in the enclosed space in the pressure regulating cabinet or pressure regulating well, so as to detect whether there is gas leakage in the pressure regulating cabinet or pressure regulating well.

[0024] The pressure sensor probe is used to connect to the gas pipeline in the pressure regulating cabinet or pressure regulating well, so as to detect the gas pressure of the gas pipeline in the pressure regulating cabinet or pressure regulating well. Description of the Drawings

[0028] The following is a further detailed description through specific embodiments:

[0029] The reference numerals in the attached drawings of the specification include: screw 1, housing 2, antenna 9, displacement switch 13, abutting end 20, connecting rod 21, second fixing hole 22, first fixing hole 23, sliding piece 24, through hole 25, sliding cavity 26, plugging cover 27, pressure sensor probe 15, water level switch 14.

[0030] Embodiment 1

[0031] Basically as shown in the attached Figure 1 drawing: The gas multi-dimensional data collector with the function of detecting cabinet doors or manhole covers includes a housing 2. The housing 2 in this embodiment is composed of an upper cover, a lower cover and a main housing. The upper cover and the lower cover are respectively located on both sides of the main housing, and the upper cover, the lower cover and the main housing are fixedly connected by screws 1.

[0032] Inside the housing 2 of this embodiment, there is a chamber. Inside the housing 2, there are a battery, a control unit and a communication module for supplying power to the whole instrument. The communication module is electrically connected to the control unit. The communication module includes an antenna 9 located on the housing 2. The control unit in this embodiment can specifically adopt a single-chip microcomputer, and the models of the single-chip microcomputer are such as Arduino Uno, STM32F103, STM32F407, ATmega2560, etc. Its function is to receive the original signals detected by the sensor devices (such as the displacement switch 13) and convert the signals into a suitable format that can be transmitted, so that the communication module can transmit to the server in a suitable signal format. The communication module in this embodiment is a DTU (Data Transfer Unit), and its function is to transmit data to a remote server or cloud platform through a mobile network (such as GSM, GPRS, LTE). The setting of the antenna 9 is used to receive and send wireless signals and enhance the receiving and sending intensity of the signals. The control unit, the communication module in this embodiment, and the control unit receive the signals of the sensor devices, convert them into a suitable format that can be transmitted, so that the communication module can transmit to the server in a suitable signal format, all of which belong to the prior art and will not be elaborated here.

[0033] The housing 2 of this embodiment is provided with a positioning module, and the positioning module is electrically connected to the control unit. The positioning module has a GPS positioning function, which is mainly realized through a GPS chip. The positioning module transmits the positioning information to the control unit, and the control unit then transmits the position of the pressure regulating well or the pressure regulating cabinet to the network server through the communication module.

[0034] The main improvement point in this embodiment is that: a displacement switch 13 electrically connected to the control unit is provided on the outer side of the housing 2. The displacement switch 13 is used to detect the cabinet door of the pressure regulating cabinet or the manhole cover of the pressure regulating well to check whether the cabinet door or the manhole cover is closed. There are various types of displacement switches 13, such as rotary displacement switches and sliding displacement switches. The displacement switch 13 in this embodiment is a sliding displacement switch 13. The sliding displacement switch is a prior art. It has normally open and normally closed contacts inside. It mainly relies on the external moving part (the cabinet door or the manhole cover in this embodiment) to collide with the connecting rod 21 of the displacement switch 13 to move linearly, thereby driving the contacts inside the displacement switch 13 to act, making the closed contacts break or the open contacts close, so as to generate corresponding signals. The end of the connecting rod 21 in this embodiment is a butting end 20 for butting against the closed cabinet door or manhole cover. In other embodiments, when a rotary displacement switch is selected, the external moving part (the cabinet door or the manhole cover in this embodiment) collides with the connecting rod 21 of the displacement switch 13 to rotate around the hinge rotation point, thereby driving the contacts inside the displacement switch 13 to act, making the closed contacts break or the open contacts close, so as to generate corresponding signals.

[0035] In this embodiment, the fixing method of the displacement switch 13 and the housing 2 is as follows: Refer to Figure 2 As shown, a plurality of first fixing holes 23 are provided on the outer shell of the displacement switch 13. The number of the first fixing holes 23 in this embodiment is four. Second fixing holes 22 are provided on the housing 2, and the number of the second fixing holes 22 is also four. The displacement switch 13 is installed on the housing 2. The first fixing holes 23 and the second fixing holes 22 are opposite to each other. The first fixing holes 23 and the second fixing holes 22 are connected with fixing parts, and the fixing parts are screws or bolts.

[0036] The multi-dimensional data collector of this embodiment is installed (for example, by screws or bolts) in a voltage regulating cabinet or a voltage regulating well, so that the cabinet door of the voltage regulating cabinet or the well cover of the voltage regulating well is opposite to the abutting end 20 of the connecting rod 21. When the cabinet door or the well cover is closed, the cabinet door or the well cover abuts against the abutting end 20, and the abutting end 20 is squeezed by the cabinet door or the well cover, and the connecting rod 21 slides on the displacement switch 13, and the contacts inside the displacement switch 13 are in a closed or open state. When the cabinet door or manhole cover is not closed, or the cabinet door or manhole cover is open, the cabinet door or manhole cover no longer abuts against the abutting end 20, and the abutting end 20 is no longer squeezed by the cabinet door or manhole cover. The connecting rod 21 recovers its deformation under the action of the spring inside the displacement switch 13. At this time, the contact inside the displacement switch 13 is in a disconnected state (if the displacement switch 13 is squeezed, the contact of the displacement switch 13 is closed, and when the displacement switch 13 is not squeezed, the contact is disconnected) or closed state (if the displacement switch 13 is squeezed, the contact of the displacement switch 13 is in a disconnected state, and when the displacement switch 13 is not squeezed, the contact is closed), thereby realizing the detection of the cabinet door or manhole cover opening state. The displacement switch 13 transmits the detected information to the control unit, and the information is then transmitted to the network server through the communication module. The staff can remotely access the server through the computer, so that they can know in time that the cabinet door or manhole cover is not closed, and the staff can arrive at the site in time to close the cabinet door or manhole cover.

[0037] In addition, in other embodiments, in order to improve the function of the gas multi-dimensional data collector, a Bluetooth module is provided on the housing 2, and the Bluetooth module is electrically connected to the control unit. The provision of the Bluetooth module enables the gas multi-dimensional data collector to have the function of Bluetooth data transmission. In this way, for on-site inspection staff, the staff can use a handheld terminal (such as a mobile phone) to connect to the gas multi-dimensional data collector through a Bluetooth connection. The gas multi-dimensional data collector transmits the collected data and other information to the handheld terminal through Bluetooth transmission. The handheld terminal displays the data collected by the gas multi-dimensional data collector, thereby facilitating the viewing of the equipment operation log and operation parameters in the pressure regulating cabinet or pressure regulating well.

[0038] In addition, in other embodiments, in order to improve the function of the gas multi-dimensional data collector, a laser methane sensor and a pressure sensor probe 15 are provided on the housing 2, and the laser methane sensor and the pressure sensor probe 15 are electrically connected to the control unit. Thus, the laser methane sensor detects the methane concentration in the pressure regulating cabinet or the pressure regulating well, and transmits the information to the control unit after the detection, and the control unit transmits the information to the communication module, and the communication module uploads the information to the server. The pressure sensor probe 15 detects the pipeline gas pressure in the pressure regulating cabinet or the pressure regulating well, and transmits the information to the control unit after the detection, and the control unit transmits the information to the communication module, and the communication module uploads the information to the server.

[0039] In addition, in other embodiments, in order to improve the functions of the present gas multi-dimensional data collector, a water level switch 14 is provided on the housing 2 (as shown in combination with Figure 3 ), and the water level switch 14 is electrically connected to the control unit. Thus, the water level switch 14 detects the accumulated water level in the pressure regulating cabinet or the pressure regulating well, transmits the detected result to the control unit after detection, the control unit transmits the information to the communication module, and the communication module uploads the information to the server.

[0040] Embodiment 2

[0041] As shown in combination with Figure 2 , the number of the second fixing holes 22 in Embodiment 1 is four, which are respectively used for connecting two first fixing holes 23. In this embodiment, the second fixing holes 22 have two rows, and each row has a plurality of second fixing holes 22, and the plurality of second fixing holes 22 in each row are arranged in sequence. The two rows of second fixing holes 22 are arranged in parallel.

[0042] Thus, the displacement switch 13 is placed on the housing 2, the first fixing holes 23 and the second fixing holes 22 are opposite to each other, and are fixed by fixing members, so that the displacement switch 13 is fixed on the housing 2. By moving the displacement switch 13 in the arrangement direction of the second fixing holes 22, the first fixing holes 23 are opposite to the second fixing holes 22 at different positions, so that the fixed installation position of the displacement switch 13 can be changed.

[0043] In this way, through this embodiment, the installation position of the displacement switch 13 is not fixed in the arrangement direction of the second fixing holes 22. If the installation position of the displacement switch 13 on the housing 2 is fixed and cannot be adjusted, when the data collector is installed in different pressure regulating cabinets or pressure regulating wells, due to the different sizes of different pressure regulating cabinets or pressure regulating wells, or there are certain errors in the installation position when the installer installs the data collector in the pressure regulating cabinet or pressure regulating well, it is impossible to ensure that the installation positions of the data collectors in each pressure regulating cabinet or pressure regulating well are exactly the same, which may cause the displacement switch 13 to be unable to normally abut against the closed cabinet door or manhole cover for detection. In this embodiment, after the gas multi-dimensional data collector is installed in the pressure regulating cabinet or pressure regulating well, if the abutting end 20 of the displacement switch 13 is far from the cabinet door or manhole cover, the displacement switch 13 can be moved in the direction close to the antenna 9 and fixedly installed to shorten the distance between the abutting end 20 of the displacement switch 13 and the cabinet door (or manhole cover), so that the abutting end 20 of the displacement switch 13 can abut against the closed cabinet door or manhole cover; if the abutting end 20 of the displacement switch 13 is close to the cabinet door or manhole cover, and the cabinet door or manhole cover abuts against the abutting end 20 of the displacement switch 13 before it is completely closed, at this time the cabinet door or manhole cover cannot be normally closed, then the displacement switch 13 can be moved in the direction away from the antenna 9 and fixedly installed to increase the distance between the abutting end 20 of the displacement switch 13 and the cabinet door (or manhole cover), so that the cabinet door or manhole cover can abut against the abutting end 20 only when it is normally closed, and the abutting end 20 of the displacement switch 13 can normally abut against the closed cabinet door or manhole cover.

[0044] In addition, if displacement switches 13 of different sizes are installed on the data collector at the time of factory shipment, or during the later use process, when the displacement switch 13 is damaged and needs to be replaced, displacement switches 13 of different sizes may be replaced. At this time, the displacement switch 13 can be fixed at the corresponding second fixing holes 22, and the installation position of the displacement switch 13 can change according to the displacement switches 13 of different sizes, so as to ensure that the displacement switch 13 normally abuts against the closed cabinet door or manhole cover for detection.

[0045] Embodiment 3

[0046] Combined with Figure 3 As shown, the row spacing between the two rows of the second fixing holes 22 in this embodiment is adjustable.

[0047] Specifically, the second fixing hole 22 in the second row on the left side is provided on the side surface of the housing 2, and the horizontal position of the second fixing hole 22 on the right side is adjustable. The specific adjustment method is as follows: A sliding cavity 26 for accommodating the sliding piece 24 is provided on the side surface of the housing 2, and an insertion opening communicating with the sliding cavity 26 is provided at the bottom of the housing 2. A plurality of second fixing holes 22 are provided on the sliding piece 24. The sliding piece 24 is inserted into the sliding cavity 26 from the insertion opening. The sliding piece 24 is located in the sliding cavity 26. The width of the sliding cavity 26 is greater than the width of the sliding piece 24 (specifically, in this embodiment, the width of the sliding cavity 26 is 3 - 5 cm, and the width of the sliding piece 24 is 1 cm), and the sliding piece 24 can slide left and right in the sliding cavity 26. The insertion opening is detachably connected with (such as a cover or snap connection) a plugging cover 27, and the plugging cover 27 plugs the insertion opening. The two ends of the sliding piece 24 respectively abut against the top end of the sliding cavity 26 and the plugging cover 27. A through hole 25 communicating with the sliding cavity 26 is provided on the side surface of the housing 2. The length of the through hole 25 is less than the length of the sliding cavity 26, and the width of the through hole 25 is equal to the width of the sliding cavity 26. At the same time, the through hole 25 communicates with the inside of the housing 2, so that the end portion of the sliding piece 24 is located in the sliding cavity 26, and the second fixing holes 22 on the sliding piece 24 can be exposed from the through hole 25.

[0048] Thus, by horizontally sliding the sliding piece 24, the distance between the two rows of second fixing holes 22 can be adjusted.

[0049] In this way, if displacement switches 13 of different models and sizes are installed on the data collector (for example, different displacement switches 13 of different models and sizes are installed on different data collectors when they leave the factory, or if the displacement switch 13 is damaged during later use, displacement switches 13 of different models and sizes may be installed for replacement), then due to the different model volumes of the displacement switches 13, the distance between the two first fixing holes 23 on the displacement switch 13 is different. When the distance between the two first fixing holes 23 on the displacement switch 13 is larger, slide the sliding piece 24 to the right to increase the distance between the two rows of second fixing holes 22, so that the first fixing holes 23 on the displacement switch 13 and the second fixing holes 22 can be aligned and fixed. When the distance between the two first fixing holes 23 on the displacement switch 13 is smaller, slide the sliding piece 24 to the left to decrease the distance between the two rows of second fixing holes 22, so that the second fixing holes 22 can adapt to the distance between the two first fixing holes 23, and the first fixing holes 23 and the second fixing holes 22 can be fixed by fixing members.

[0050] In summary, the row spacing between the two rows of second fixing holes 22 is adjustable, so as to adapt to the displacement switches 13 with different spacings of the first fixing holes 23, and displacement switches 13 of different models and sizes can be installed on the data collector.

[0051] The above method is to set a sliding piece 24 to realize the adjustment of the row spacing between the two rows of second fixing holes 22. Of course, in other embodiments, two sliding pieces 24 can also be set. The two sliding pieces 24 are respectively located in two different sliding cavities 26 and slide horizontally in the two different sliding cavities 26. The two rows of second fixing holes 22 are respectively located on the two sliding pieces 24. At this time, sliding the two sliding pieces 24 can also realize the adjustment of the distance between the two rows of second fixing holes 22.

[0052] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
