Description

Technical Field

[0001] The present invention relates to the technical field of oxygen content detectors, and particularly to an oxygen content detector. Background Art

[0002] A boiler is a device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium water or other fluids to a certain parameter. When the boiler burns, oxygen is required. In order to monitor the oxygen content in the boiler, an oxygen content detector is needed.

[0003] When existing oxygen content detectors are in use, a controller is required. The oxygen content detector and the controller are connected by a data cable. Usually, technicians will plug the oxygen content detector into the installation hole on the side wall of the boiler, and then use bolts to fix the controller to the outer wall of the boiler.

[0004] When installing the controller, since technicians need to install multiple bolts with tools, the assembly process of the controller is relatively cumbersome, which is not conducive to technicians for maintenance. Summary of the Invention

[0005] In view of this, the present invention provides an oxygen content detector to solve the problem that the assembly process is relatively cumbersome when installing the controller on the boiler.

[0006] In a first aspect, the present invention provides an oxygen content detector, which includes:

[0007] A detection instrument for detecting the oxygen content;

[0008] A controller communicatively connected to the detection instrument; a fixing mechanism is provided on the outer shell of the controller; a clamping block is movably provided on the fixing mechanism. Under an external force, the clamping block has a first position protruding from the fixing mechanism and a second position received in the fixing mechanism;

[0009] A fixing frame adapted to be provided on the outer wall of the boiler; an installation area for fixing the controller is provided on the fixing frame, and a groove is provided in the installation area;

[0010] After the controller is placed in the installation area, the clamping block is aligned with the groove; and when the clamping block is in the first position, the clamping block is embedded in the groove to fix the controller to the fixing frame; when the clamping block is in the second position, the clamping block disengages from the groove to separate the controller from the fixing frame.

[0011] Beneficial effects: In this embodiment, a fixing frame is pre - installed on the outer wall of the boiler, and a fixing mechanism adapted to be installed in cooperation with the fixing frame is provided on the controller. During actual use, the fixing mechanism can be directly installed on the fixing frame. When the clamping block protrudes, the fixing is completed. Compared with traditional bolt fixing, 90% of the installation time is saved, and there is no need to install multiple bolts with tools. At the same time, during disassembly, only the position of the clamping block needs to be directly toggled, so that the controller can be separated from the fixing frame. It can be seen from this that through the cooperation of the fixing frame and the fixing mechanism in this embodiment, the assembly process of the controller can be simplified, facilitating maintenance by technicians.

[0012] In an alternative embodiment, the fixing mechanism includes:

[0013] A fixing block, provided on the outer shell of the controller; a receiving groove is formed on the fixing block;

[0014] A first reset member, provided in the receiving groove; one end of the first reset member is connected to the bottom of the receiving groove, and the other end of the first reset member is connected to the clamping block;

[0015] Under the action of an external force, the clamping block overcomes the elastic force of the first reset member, protrudes out of the receiving groove and protrudes from the fixing block, and after the external force disappears, under the elastic force of the first reset member, the clamping block moves back into the receiving groove.

[0016] Beneficial effects: In this embodiment, by using the first reset member, when technicians actually disassemble, they only need to remove the external force fixing the clamping block, and the clamping block will automatically reset under the elastic force of the first reset member. Thus, there is no need to manually reset the clamping block, which can further reduce the assembly operations of technicians and improve their work efficiency.

[0017] In an alternative embodiment, the fixing mechanism further includes:

[0018] A through - hole, formed on the side wall of the fixing block and communicating with the receiving groove;

[0019] A driving assembly, provided on the outer shell of the controller; the driving end of the driving assembly passes through the through - hole and abuts against the clamping block;

[0020] The driving end has a first state in which it pushes the clamping block out of the receiving groove during movement, and a second state in which it separates from the clamping block. After the driving end separates from the clamping block, the clamping block moves back into the receiving groove under the elastic force of the first reset member.

[0021] In an alternative embodiment, a contact portion is provided on one side of the clamping block close to the driving end, and the contact portion is provided with a first inclined surface that slopes upward; a second inclined surface that slopes downward is provided at one end of the driving end close to the contact portion; when the clamping block abuts against the driving end, the first inclined surface fits with the second inclined surface;

[0022] When the driving end moves close to the clamping block, the first inclined surface and the second inclined surface are used to push the clamping block out of the receiving groove.

[0023] In an alternative embodiment, the driving assembly includes:

[0024] An operating portion, movably provided on the housing of the controller;

[0025] A connecting rod, one end of the connecting rod is connected to the operating portion, and the other end of the connecting rod is provided with the contact portion;

[0026] Under the action of an external force, the operating portion drives the connecting rod to move close to the clamping block or away from the clamping block.

[0027] In an alternative embodiment, the driving assembly further includes:

[0028] A base, provided on the housing of the controller;

[0029] A sliding groove, opened on the base; the extending direction of the sliding groove matches the movement stroke of the operating portion; a slider is provided at the bottom of the operating portion, and the slider is adapted to be embedded in the sliding groove for sliding.

[0030] In an alternative embodiment, the driving assembly further includes:

[0031] A spring member, provided in the sliding groove; one end of the spring member is connected to the sliding groove, and the other end of the spring member is connected to the operating portion;

[0032] Under the action of an external force, the operating portion drives the connecting rod to move close to the clamping block, and the spring member is stretched; after the external force disappears, under the elastic force of the spring member, the operating portion drives the connecting rod to move away from the clamping block.

[0033] In an alternative embodiment, the oxygen content detector further includes:

[0034] A wire clamping board, movably connected to the housing of the controller; the wire clamping board is provided with wire passing holes, and the wire passing holes correspond to the wiring holes on the controller one by one;

[0035] A wire clamp assembly, provided on the wire clamping board and corresponding to the wire passing holes;

[0036] When the wire passes through the wire passing hole, the wire clamp assembly is adapted to fix the wire.

[0037] Beneficial effects: Since there is currently no device on the controller for fixing the wire, the wire and the wiring hole are often loosened during use, resulting in the controller being unable to normally receive the data transmitted by the oxygen content sensor. In this embodiment, by using the wire clamping plate and the wire clamp assembly, after the wire passes through the wire passing hole on the wire clamping plate, the wire clamp assembly can directly fix the wire, thereby preventing the wire from loosening from the wiring hole and improving the overall stability of the device during operation.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0071] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can also be the communication inside two components. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0072] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0073] A boiler is a device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium water or other fluids to a certain parameter. Oxygen is required when the boiler is burning. In order to monitor the oxygen content in the boiler, an oxygen content detector is needed. When the existing oxygen detectors are in use, a controller 2 is required. The oxygen detector is connected to the controller 2 through a data cable. Usually, technicians will insert the oxygen detector into the installation hole on the side wall of the boiler, and then use bolts to fix the controller 2 to the outer wall of the boiler. Since technicians need to install multiple bolts through tools when installing the controller 2, the assembly process of the controller 2 is relatively cumbersome, which is not conducive to technicians for maintenance.

[0074] In view of this, the present invention provides an oxygen detector to solve the problem that the assembly process is relatively cumbersome when installing the controller 2 on the boiler.

[0075] The following will be combined with Figures 1 to 8 , to describe the embodiments of the present invention.

[0076] According to an embodiment of the present invention, on the one hand, an oxygen detector is provided. The oxygen detector includes a detection instrument 1, a controller 2, and a fixing bracket.

[0077] Specifically, in this embodiment, the detection instrument 1 is used to detect the oxygen content. The detection instrument 1 may include a metal tube sleeve 11, an intake pipe 12, and a detection head 13. The intake pipe 12 is installed at the bottom of the metal tube sleeve 11, the detection head 13 is installed at the end of the intake pipe 12, and the signal output end of the detection head 13 is connected to the controller 2 through a wire.

[0078] In this embodiment, a display panel 22 is installed on one side of the controller 2, and a wiring hole 21 is opened on the back of the controller 2. The controller 2 is communicatively connected to the detection instrument 1. For the communication connection method, the above-mentioned wire communication can be adopted, or wireless communication can be adopted. Of course, this embodiment is only an example of the communication method between the controller 2 and the detection instrument 1, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effect can be achieved.

[0079] Further, in this embodiment, a fixing mechanism 3 is provided on the outer shell 23 of the controller 2. A clamping block 31 is movably provided on the fixing mechanism 3. Under the action of an external force, the clamping block 31 has a first position protruding from the fixing mechanism 3 and a second position received in the fixing mechanism 3. For the form of the external force acting on the clamping block 31, it can be manually operated by a technician, or a driving motor can be used to drive the clamping block 31 to move. Of course, this embodiment is only an example of the form of the external force acting on the clamping block 31, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effect can be achieved.

[0080] Further, in this embodiment, the fixing frame is adapted to be provided on the outer wall of the boiler. An installation area for fixing the controller 2 is provided on the fixing frame, and a groove is opened in the installation area. For the fixing frame, it can be pre-installed on the outer wall of the boiler by a technician, or it can be integrally formed with the outer wall of the boiler.

[0081] During actual operation, after the controller 2 is placed in the installation area, first move the clamping block 31 to the second position, and then align the clamping block 31 with the groove. Then move the clamping block 31 to the first position, so that the clamping block 31 can be embedded into the groove, and further the controller 2 is fixed to the fixing frame. Similarly, when disassembling, first move the clamping block 31 from the first position to the second position, and at this time the clamping block 31 can be disengaged from the groove, so as to separate the controller 2 from the fixing frame.

[0082] With such a setting, in this embodiment, a fixing frame is pre-set on the outer wall of the boiler, and a fixing mechanism 3 adapted to be installed in cooperation with the fixing frame is provided on the controller 2. During actual use, the fixing mechanism 3 can be directly installed on the fixing frame. When the clamping block 31 protrudes, the fixing is completed, saving 90% of the installation time compared with the traditional bolt fixing, and there is no need to install multiple bolts through tools. At the same time, when disassembling, it only needs to directly move the position of the clamping block 31, so that the controller 2 can be separated from the fixing frame. It can be seen from this that through the cooperation of the fixing frame and the fixing mechanism 3 in this embodiment, the assembly process of the controller 2 can be simplified, which is convenient for technicians to maintain.

[0083] Further, in an alternative embodiment, the fixing mechanism 3 includes a fixing block 32 and a first reset member 34. Specifically, the fixing block 32 is disposed on the outer shell 23 of the controller 2, and a receiving groove 33 is formed in the fixing block 32. The first reset member 34 is disposed in the receiving groove 33, and one end of the first reset member 34 is connected to the bottom of the receiving groove 33, and the other end of the first reset member 34 is connected to the clamping block 31. In this embodiment, the first reset member 34 can be a reset spring or other objects that achieve the reset function.

[0084] During actual installation, under the action of an external force, such as a technician manually operating the clamping block 31, the clamping block 31 overcomes the elastic force of the first reset member 34, extends out of the receiving groove 33 and protrudes from the fixing block 32. At this time, a small component is used to clamp the clamping block 31. When disassembling the controller 2, the technician can manually remove the small component. Then, after the external force that the small component clamps the clamping block 31 disappears, under the elastic force of the first reset member 34, the clamping block 31 moves back into the receiving groove 33.

[0085] Of course, this embodiment is only an example of the way to fix the clamping block 31, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation. For example, gluing or other fixing methods can also be used as long as the same technical effect can be achieved.

[0086] With such a setting, in this embodiment, by using the first reset member 34, when the technician actually disassembles, only the external force fixing the clamping block 31 needs to be removed, and the clamping block 31 will automatically reset under the elastic force of the first reset member 34. Furthermore, there is no need to manually reset the clamping block 31, which can further reduce the assembly operation of the technician and improve the work efficiency of the technician.

[0087] Further, in an alternative embodiment, the fixing mechanism 3 further includes a through hole 35 and a driving assembly 36.

[0088] Specifically, in this embodiment, the through hole 35 is formed in the side wall of the fixing block 32 and communicates with the receiving groove 33. The driving assembly 36 is disposed on the outer shell 23 of the controller 2, and the driving end 361 of the driving assembly 36 passes through the through hole 35 and abuts against the clamping block 31.

[0089] During the actual working process, the driving end 361 has a first state of ejecting the clamping block 31 out of the receiving groove 33 and a second state of separating from the clamping block 31 during movement. After the driving end 361 separates from the clamping block 31, the clamping block 31 moves back into the receiving groove 33 under the elastic force of the first reset member 34.

[0090] That is to say, during installation, after the driving end 361 of the driving component 36 passes through the through hole 35, it directly drives the clamping block 31 to move, so that the clamping block 31 can be stably embedded into the groove of the fixing frame. During disassembly, the driving end 361 of the driving component 36 is separated from the clamping block 31, and the clamping block 31 can move back into the receiving groove 33 under the elastic force of the first resetting member 34.

[0091] Further, in an optional embodiment, a contact portion 311 is provided on one side of the clamping block 31 close to the driving end 361, and the contact portion 311 is provided with a first inclined surface that slopes upward. A second inclined surface that slopes downward is provided at one end of the driving end 361 close to the contact portion 311. When the clamping block 31 abuts against the driving end 361, the first inclined surface fits with the second inclined surface.

[0092] When the driving end 361 moves close to the clamping block 31, a relative displacement is generated between the driving end 361 and the clamping block 31. Under the action of the first inclined surface and the second inclined surface, the closer the driving end 361 moves to the clamping block 31, the longer the length of the clamping block 31 protruding from the receiving groove 33. In this way, the first inclined surface and the second inclined surface can be used to eject the clamping block 31 out of the receiving groove 33.

[0093] Further, in an optional embodiment, the driving component 36 includes an operating portion 362 and a connecting rod 363.

[0094] Specifically, in the embodiment of the present invention, the operating portion 362 is movably provided on the housing 23 of the controller 2. One end of the connecting rod 363 is connected to the operating portion 362, and the other end of the connecting rod 363 is provided with the contact portion 311.

[0095] During actual use, under the action of an external force, for example, it can be manually operated by a technician, or a power motor can be used to drive the operating portion 362 to move. In this way, the operating portion 362 can drive the connecting rod 363 to move close to the clamping block 31 or away from the clamping block 31.

[0096] Further, in an optional embodiment, the driving component 36 further includes a base 364 and a sliding groove 365.

[0097] Specifically, in this embodiment, the base 364 is provided on the housing 23 of the controller 2. The sliding groove 365 is opened on the base 364. The extending direction of the sliding groove 365 matches the movement stroke of the operating portion 362. A slider 367 is provided at the bottom of the operating portion 362, and the slider 367 is adapted to be embedded in the sliding groove 365 for sliding.

[0098] Further, in an alternative embodiment, the driving component 36 further includes a spring member 366 disposed in the sliding groove 365. One end of the spring member 366 is connected to the sliding groove 365, and the other end of the spring member 366 is connected to the operating portion 362.

[0099] Under the action of an external force, the operating portion 362 drives the connecting rod 363 to move closer to the latch 31, and the spring member 366 is stretched. At this time, the spring member 366 accumulates elastic force. After the external force disappears, under the elastic force of the spring member 366, the operating portion 362 drives the connecting rod 363 to move away from the latch 31.

[0100] Further, in an alternative embodiment, the oxygen detector further includes a wire clamping plate 4 and a wire clip assembly 5.

[0101] Specifically, in this embodiment, the wire clamping plate 4 is movably connected to the housing 23 of the controller 2. The wire clamping plate 4 is provided with wire passing holes, which correspond to the wiring holes 21 on the controller 2 one by one. The wire clip assembly 5 is disposed on the wire clamping plate 4 and is correspondingly arranged with the wire passing holes. When the wire passes through the wire passing holes, the wire clip assembly 5 is adapted to fix the wire. When the wire is to be disconnected, it is necessary to operate the wire clip assembly 5 correspondingly to release the wire, so as to complete the disassembly.

[0102] With such a setting, since there is currently no device for fixing the wire on the controller 2, the wire is often disconnected from the wiring hole 21 during use, resulting in the controller 2 being unable to normally receive the data transmitted by the oxygen content sensor. However, in this embodiment, by using the wire clamping plate 4 and the wire clip assembly 5, after the wire passes through the wire passing holes on the wire clamping plate 4, the wire clip assembly 5 can directly fix the wire, thereby preventing the wire from being disconnected from the wiring hole 21 and improving the overall stability of the device during operation.

[0103] Further, in an alternative embodiment, the wire clip assembly 5 includes a first wire clip and a second wire clip.

[0104] Specifically, in this embodiment, the first wire clip is movably disposed on the wire clamping plate 4, and the second wire clip is movably disposed on the wire clamping plate 4. The second wire clip is correspondingly arranged with the first wire clip.

[0105] Under the action of an external force, which can be manually operated by a technician or automatically operated by a power motor, the first wire clip and the second wire clip move closer to each other to fix the wire and move away from each other to make the wire movable.

[0106] Of course, this embodiment is only an example to illustrate the external force method, but it is not limited to this. Those skilled in the art can make changes according to actual conditions as long as the same technical effect can be achieved.

[0107] Furthermore, in an optional embodiment, the wire clamp assembly 5 further includes a second reset member 53 , and the second reset member 53 is disposed simultaneously between the first wire clamp and the wire clamping plate 4 and between the second wire clamp and the wire clamping plate 4 .

[0108] Under the action of external force, the first wire clamp and the second wire clamp move away from each other to make the wire move, and the second reset member 53 is compressed. In this case, the technician can insert the wire into the wire hole. After the wire is installed, the external force can be removed. After the external force disappears, under the elastic force of the second reset member 53, the first wire clamp and the second wire clamp are driven to move closer to each other to fix the wire.

[0109] Therefore, in this embodiment, the elastic force of the second restoring member 53 acts on the first wire clamp and the second wire clamp, so that the first wire clamp and the second wire clamp clamp the wire, thereby fixing the wire.

[0110] Furthermore, in an optional embodiment, the first wire clamp and the second wire clamp are provided with an arc-shaped clamping plate 51 on a side close to the wire, and the arc-shaped clamping plate 51 is in contact with the wire.

[0111] Specifically, a connecting rod 52 may be further provided on the arc-shaped clamping plate 51 , and the bottom of the connecting rod 52 cooperates with the second resetting member 53 , thereby realizing the reciprocating motion of the first wire clamp and the second wire clamp.

[0112] Furthermore, in an optional implementation, the oxygen detector also includes a mounting seat 6 and a card slot 7 .

[0113] Specifically, the mounting seat 6 is arranged on the housing 23 of the controller 2, and the mounting seat 6 is provided with a mounting groove 61 and an elastic buckle 62, and the mounting groove 61 is suitable for the docking piece 41 of the clamping plate 4 to be embedded. The elastic buckle 62 can be composed of a clamping spring 621, a moving rod 622, and a toggle rod 623. The spring is arranged in the mounting seat 6, one end of the moving rod 622 is connected to the spring, and the other end of the moving rod 622 is suitable for extending from and into the mounting groove 61, and the toggle rod 623 is connected to the moving rod 622. In actual use, the technician can manually operate the toggle rod 623, thereby driving the moving rod 622 to extend in and out of the mounting groove 61, thereby realizing the switching between locking and unlocking.

[0114] Further, the card slot 7 is provided at the end of the wire clamping board 4. After the docking member 41 of the wire clamping board 4 is inserted into the installation slot 61, the card slot 7 is correspondingly arranged with the elastic buckle 62. Moreover, after the docking member 41 of the wire clamping board 4 is inserted into the installation slot 61, during the operation of technicians, the moving rod 622 extends into the installation slot 61, so that the elastic buckle 62 has a first state of opening the installation slot 61, and a second state of resetting or inserting into the card slot 7 after the external force disappears.
