Description

Technical Field

[0001] The invention relates to the technical field of gas meter counting, and in particular to a black-and-white disk steel shell light-reflection integrated counter. Background Art

[0002] At present, the sampling and counting method of intelligent gas meter measurement on the market is realized by light transmitters, light receivers and light reflective surfaces: the light reflective surface is set on the signal output gear, and the light transmitters and light receivers are welded on the sampling printed circuit board as components and fixed on both sides of the signal output gear. The light transmitter alternately delivers light to light reflective surfaces of different colors. The two reflective surfaces have different degrees of absorption and reflection of light, and the light signal intensity received by the light receiver is different. At the same time, the signal is transmitted to the main control unit on the control motherboard. After processing by the main control unit, the number of revolutions of the sampling signal output gear can be determined through logical judgment to realize gas volume measurement, and then output to the remote meter reading system, pre-charge, payment system and other data units.

[0003] In the prior art, the projection positions of the light emitter and the light receiver on the signal output gear need to be on the light reflecting surface to work properly. Since there is a certain distance between the control main board and the signal output gear, and the position of the signal output gear on the counter is relatively fixed, the distance between the light emitter, the light receiver and the light reflecting surface is fixed. Moreover, the size specifications of the control main board vary during production. If the position of the light emitter and the light receiver is larger than the distance of the signal output gear after the initial installation of the control main board, the light receiver may not be able to receive the light signal emitted by the light emitter through the light reflecting surface, thereby causing counting errors in the counter. Therefore, there is room for improvement. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention aims to provide a black-and-white disk steel shell light-reflecting integrated counter. The present invention can accurately adjust the distance between the control main board and the signal output gear during assembly, thereby controlling the relative positions of the light reflector, the light receiver and the light reflecting surface to ensure the counting accuracy of the counter. The specific scheme is as follows:

[0006] The position adjustment mechanism is used to control the movement of the counter frame to achieve the position adjustment of the signal output gear in the front-back and left-right directions relative to the control main board, including a left slider, a left guide rail, a right slider, and a right guide rail. The left slider and the right slider are respectively arranged on both sides of the top wall of the counter frame, and the left guide rail and the right guide rail can be fixedly installed on the inner top wall of the gas meter. The left guide rail and the right guide rail are respectively formed with a left cross groove and a right cross groove, and the left slider and the right slider are respectively limited and slidable in the left cross groove and the right cross groove;

[0007] The light display mechanism includes a horizontal light rack, a horizontal LED light group, a vertical light rack, and a vertical LED light group. The horizontal light rack and the vertical light rack are both arranged on the side wall of the counter rack.

[0008] The electric control mechanism includes a lateral pressure switch group, a vertical pressure switch group, a power supply, and a controller. The power supply is used for power supply. The lateral pressure switch group and the vertical pressure switch group are respectively arranged on two vertically arranged side walls in the left cross slide. The lateral pressure switch group and the vertical pressure switch group are respectively arranged corresponding to the lateral LED light group and the vertical LED light group. The lateral pressure switch group and the vertical pressure switch group each include a plurality of pressure switches arranged evenly at intervals. The distance between two adjacent pressure switches is set as one adjustment displacement. The pressure switch is connected to the input end of the controller, and the output end of the controller is connected to the LED light.

[0009] Furthermore, the connection between the pressure switch and the left guide rail is an elastic connection.

[0010] Furthermore, a mounting groove is provided on the left guide rail corresponding to the pressure switch, and an elastic block which can be deformed under pressure is provided in the mounting groove.

[0011] Furthermore, one end of the horizontal lamp rack is connected to one end of the vertical lamp rack, and a fastening bolt is passed through the connecting portion of the horizontal lamp rack and the vertical lamp rack, and the fastening bolt is threadedly connected to the counter rack.

[0012] Furthermore, numerical display areas are provided on the horizontal lamp rack and the vertical lamp rack corresponding to the lighting direction of the LED lamp.

[0013] Furthermore, the power source is a rechargeable battery, and the electric control mechanism also includes a kinetic energy power generation component, which is transmission-connected to the signal output wheel and electrically connected to the power source.

If the position of the light reflection surface is offset, the staff can apply force to the counter frame, and the left slider and the right slider move on the left guide rail and the right guide rail respectively, driving the entire counter frame to move in the front-back or left-right direction, thereby adjusting the position of the light reflection surface to the optimal position. At the same time, during the movement of the counter frame, the left slider will squeeze the pressure switch in the horizontal pressure switch group or the vertical pressure switch group when it moves. After the pressure switch is subjected to force, it will feedback to the controller, and the controller will control the corresponding horizontal LED light group or the vertical LED light group in the LED lights to light up in sequence. Other staff can intuitively understand the displacement direction and accuracy of the light reflection surface according to the number of LED lights in the horizontal LED light group or the vertical LED light group that are lit. In summary, the present invention can accurately adjust the distance between the control mainboard and the signal output gear during assembly, thereby controlling the relative positions of the light reflector, the light receiver and the light reflecting surface, ensuring the counting accuracy of the counter. In addition, it is convenient for the staff to uniformly debug the counters of the same type with installation errors according to the lighting state of the LED lights of the light display mechanism, thereby improving production efficiency.

[0017] (2) By setting fastening bolts, the horizontal lamp rack and the vertical lamp rack can be quickly and detachably installed on the counter rack at the same time, which is convenient to operate. By setting a numerical display area, the staff can also know the displacement length of the light reflecting surface in the front-back or left-right direction according to the numerical value corresponding to the LED light at the end in the lighting state;

[0018] (3) By setting up a kinetic energy power generation component, the signal output gear will rotate during operation, driving the transmission gear to rotate, and the micro-generator will be driven to work through the speed increase gear to store energy, converting kinetic energy into electrical energy, thereby supplying power to the power supply, making full use of the kinetic potential energy of the counter, and realizing the recycling of the light display mechanism.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0025] Combination Figures 1 to 4 A black and white plate steel shell light reflection integrated counter is provided in a gas meter, generally installed at the upper end of the gas meter, and is used to measure the gas usage of the gas meter. The counter includes a counter frame 1, a character wheel group 2, a signal input gear 3, and a signal output gear 4, which are all necessary structures in the prior art. The character wheel group 2 and the signal input gear 3 are both rotatably mounted on the counter frame 1. The character wheel group 2 includes a first character wheel, the signal input gear 3 is connected to the first character wheel by transmission, and the signal output gear 4 is meshed with the signal input gear 3. The signal output gear 4 is connected to the control main board signal on the gas meter that does not belong to the counter. The signal output gear 4 receives the signal and feeds it back to the control main board for processing, and then outputs it to the external remote meter reading system, pre-charge, payment system and other data units.

[0026] The signal output gear 4 is provided with a light reflecting surface for cooperating with the control mainboard. In this embodiment, the light reflecting surface includes a black reflecting surface 41 and a white reflecting surface 42, which can reflect the irradiated light. The black reflecting surface 41 and the white reflecting surface 42 are symmetrically distributed on the surface of the signal output gear 4 with the diameter of the signal output gear 4 as the symmetry line. Correspondingly, the control mainboard is provided with a light transmitter and a light receiver. When the counter works normally, the light transmitter delivers light to the black reflecting surface 41 and the white reflecting surface 42. Based on the different absorption and reflection degrees of light by the black reflecting surface 41 and the white reflecting surface 42, when the light receiver can receive the reflected light, it will receive different light signal intensities.

[0027] Different from the counter on the existing gas meter, in order to facilitate the adjustment of the relative positions of the light reflector, light receiver and light reflecting surface, and to facilitate the staff to intuitively understand the position adjustment parameters, the counter frame 1 is provided with a position adjustment mechanism, a light display mechanism 9 and an electric control mechanism 11.

[0028] The position adjustment mechanism is used to control the movement of the counter frame 1 to achieve position adjustment of the signal output gear 4 in the front and rear and left and right directions relative to the control main board, including a left slider 5, a left guide rail 6, a right slider 7, and a right guide rail 8. The left slider 5 and the right slider 7 are respectively fixed on both sides of the top wall of the counter frame 1. The left guide rail 6 and the right guide rail 8 can be fixedly installed on the inner top wall of the gas meter. The left guide rail 6 and the right guide rail 8 are respectively formed with a left cross slide groove 61 and a right cross slide groove 81. One end of the two slide grooves in the left and right directions is set as an open end, which is convenient for pushing the left slider 5 and the right slider 7 into the left cross slide groove 61 and the right cross slide groove 81. The other ends are all closed ends to prevent the left slider 5 and the right slider 7 from falling out. The left slider 5 and the right slider 7 are limitedly slid in the left cross groove 61 and the right cross groove 81 respectively. The shape of the groove can be set as a dovetail groove to prevent the left slider 5 and the right slider 7 from falling out of the left cross groove 61 and the right cross groove 81 under the gravity of the counter. When the counter frame 1 is subjected to thrusts in different directions, the left slider 5 and the right slider 7 slide in the left cross groove 61 and the right cross groove 81 in different directions, so that the counter frame 1 is adjusted relative to the gas meter, that is, the light reflection surface is adjusted relative to the control main board.

[0029] Since the position adjustment mechanism is arranged between the top of the counter frame 1 and the gas meter, and the distance between the two is small, it is difficult for the staff to see the specific movement of the position adjustment mechanism. The light display mechanism 9 is used to display the light according to the movement state of the position adjustment mechanism, so that the staff can intuitively understand the situation. In detail, the light display mechanism 9 includes a horizontal light rack 91, a horizontal LED light group 92, a vertical light rack 93, and a vertical LED light group 94. The horizontal light rack 91 and the vertical light rack 93 are both fixed on the side wall of the counter frame 1. Specifically, one end of the horizontal light rack 91 is connected to one end of the vertical light rack 93, and the whole is L-shaped. The connection between the horizontal light rack 91 and the vertical light rack 93 is penetrated by a fastening bolt, and the fastening bolt is threadedly connected to the counter frame 1 for easy quick assembly. The horizontal LED light group 92 includes a plurality of LED lights arranged at intervals on the horizontal light rack 91, and the vertical LED light group 94 includes a plurality of LED lights arranged at intervals on the vertical light rack 93. For easy distinction, different colors are selected for the light-emitting colors of the LED lights in the horizontal LED light group 92 and the vertical LED light group 94. Optimally, a numerical display area 10 is provided on the horizontal light rack 91 and the vertical light rack 93 along the lighting direction of the LED lights. The numerical display area 10 is specifically the Arabic numerals that gradually increase in the left, right, upward and downward directions, with the left slider 5 being the coordinate reference zero point when the left slider 5 is in the center position. The more LED lights are lit in a certain direction, the larger the corresponding Arabic numerals are, which means that the displacement length of the light reflecting surface along a certain direction is longer. By setting the numerical display area 10, the staff can also know the displacement length of the light reflecting surface in the front and back or left and right directions according to the numerical values ​​corresponding to the LED lights at the end that are in the lit state.

[0030] The electric control mechanism 11 is used to supply power to the light display mechanism 9 and trigger the light display mechanism 9 to work, including a horizontal pressure switch group 111, a vertical pressure switch group 112, a power supply 113, and a controller 114. The power supply 113 is used for power supply. The horizontal pressure switch group 111 and the vertical pressure switch group 112 are respectively arranged on two vertically arranged side walls in the left cross chute 61. The horizontal pressure switch group 111 and the vertical pressure switch group 112 are respectively arranged corresponding to the horizontal LED light group 92 and the vertical LED light group 94. The horizontal pressure switch group 111 and the vertical pressure switch group 112 both include a plurality of pressure switches evenly spaced. As can be seen from the figure, the number of pressure switches in the upper, lower, left, right and middle positions is the same, with the center point of the left cross chute 61 as the boundary. The pressure switch is connected to the input end of the controller 114, and the output end of the controller 114 is connected to the LED light. When a pressure switch is squeezed by force, it is fed back to the controller 114, and the controller 114 is convenient for controlling the corresponding LED light to be lit.

[0031] In order to prevent the pressure switch from hindering the sliding of the left slider 5, the connection between the pressure switch and the left guide rail 6 is an elastic connection. A mounting groove is provided on the left guide rail 6 corresponding to the pressure switch. A pressure-deformable elastic block is provided in the mounting groove. The elastic block can be made of rubber. The two ends of the elastic block are respectively connected to the left guide rail 6 and the pressure switch. The end of the pressure switch is slightly exposed outside the mounting groove. When the left slider 5 contacts the pressure switch, the pressure switch is compressed, causing the elastic block to be squeezed, so that the pressure switch will shrink and completely enter the mounting groove.

[0032] The distance between two adjacent pressure switches is set as a single adjustment displacement, which is calculated according to the effective reflection range of the light reflection surface when manufacturing the left guide rail 6, and then the length of the single adjustment displacement is determined.

[0033] After the control mainboard in the counter is installed stably, the light emitter, light reflecting surface and light receiver can be debugged to see whether they work normally according to the initial distance between the control mainboard and the signal output gear 4. If the position of the light reflecting surface is offset, the staff can apply force to the counter frame 1, and the left slider 5 and the right slider 7 move on the left guide rail 6 and the right guide rail 8 respectively, driving the entire counter frame 1 to move in the front-back or left-right direction, thereby adjusting the position of the light reflecting surface to the optimal position. At the same time, during the movement of the counter frame 1, the left slider 5 will squeeze the pressure switch in the horizontal pressure switch group 111 or the vertical pressure switch group 112 during movement. After the pressure switch is subjected to force, it will be fed back to the controller 114. The controller 114 controls the corresponding horizontal LED light group 92 or the vertical LED light group 94 to light up the LED lights in turn. Other staff can intuitively understand the displacement direction and accuracy of the light reflecting surface according to the number of LED lights in the horizontal LED light group 92 or the vertical LED light group 94 that are lit.

[0034] After the lighting display mechanism 9 and the electric control mechanism 11 are assembled in the gas meter, it is inconvenient to disassemble the parts of the gas meter as a sensitive instrument during normal operation. If the power supply 113 is used up, if the staff needs to replace the power supply 113, this operation is troublesome. Therefore, in the present invention, the power supply 113 is set as a rechargeable battery, and the electric control mechanism 11 also includes a kinetic energy power generation component 12, which is connected to the signal output wheel in a transmission manner, and the kinetic energy power generation component 12 is electrically connected to the power supply 113, and the kinetic energy generated when the signal output gear 4 rotates is utilized. The kinetic energy power generation component 12 includes a transmission gear 121, a speed increase gear 122, and a micro generator 123. The transmission gear 121 is coaxially arranged on the signal output gear 4, and the transmission gear 121 is meshed with the speed increase gear 122. The speed increase gear 122 is rotatably installed on the counter frame 1. The micro generator 123 adopts a micro power generation system based on Faraday distance, including existing components such as a stator and a rotor, and is fixedly installed on the counter frame 1, and the input shaft of the micro generator 123 is coaxially connected with the speed increase gear 122. When the counter is working normally, the signal output gear 4 will rotate during operation, driving the transmission gear 121 to rotate, and driving the micro-generator to work to store energy through the speed increase gear 122, converting kinetic energy into electrical energy, thereby powering the power supply 113, so that the lighting display mechanism 9 and the electronic control mechanism 11 can both work in standby mode for a long time, making full use of the kinetic potential energy of the counter and realizing the recycling of the lighting display mechanism 9.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
