Description

Technical Field

[0001] The invention belongs to the technical field of monitoring and alarm equipment, and in particular is a monitoring and alarm device for a heating and heat exchange station. Background Art

[0002] The monitoring and alarm equipment of the heating heat exchange station is a comprehensive system that integrates multiple sensors and alarm mechanisms. It is designed to monitor the operating status of the heat exchange station in real time and issue an alarm in time when an abnormality occurs to ensure the safe and efficient operation of the heat exchange station.

[0003] However, the existing monitoring and alarm devices of heating and heat exchange stations still have drawbacks in actual use: the shell of the monitoring alarm is generally provided with a plurality of slots for heat dissipation and amplifying the alarm sound, but inside the heating and heat exchange station, the monitoring and alarm device installed on the pipeline for detecting flow leakage problems will be blocked by external dust on the shell of the alarm during long-term use, thereby significantly affecting the subsequent heat dissipation and the alarm sound. The blocked shell can only rely on manual removal of the monitoring and alarm device or opening the monitoring and alarm device for cleaning, which is time-consuming and labor-intensive, and therefore needs to be improved. Summary of the invention

[0004] In order to solve the problem of the monitoring and alarm device installed on the pipeline for detecting flow leakage proposed in the above background technology, during long-term use, the external dust will block the slots on the alarm shell, and then significantly affect the subsequent heat dissipation and alarm sound. The blocked shell can only rely on manual removal of the monitoring and alarm device or opening the monitoring and alarm device for cleaning, which is time-consuming and labor-intensive. The present invention provides a monitoring and alarm device for a heating and heat exchange station. By setting a first air groove and a bellows and other structures, an embedded and movable design is used on the monitoring and alarm device shell to improve the cleaning efficiency of the slots on the shell; by setting a rack and a spring sheet and other structures, the cleaning efficiency is improved through the reciprocating swinging movement of the movable plate based on the wind blowing; by setting a locking component, a movable component and a moving component and other structures, the original slot is fixedly installed on the shell, and it is changed into a swingable design, and the operation can be completed by a slight manual pull.

[0005] To achieve the above object, the present invention provides the following technical solution: a monitoring and alarm device for a heating heat exchange station, comprising a monitoring and alarm housing and a cover plate, and also comprising:

[0006] A movable component, wherein the movable component is arranged inside the cover plate;

[0007] An extrusion assembly, wherein the extrusion assembly is installed on both sides of the inner cavity of the cover plate, and a moving assembly is installed on the side away from the moving assembly;

[0008] The movable assembly includes a movable plate and a rotating shaft, wherein the movable plate is connected to the cover plate bearing via the rotating shaft, a first air groove is provided inside the movable plate, and a spur gear is installed on the outer wall of the rotating shaft at one end inside the cover plate;

[0009] The extrusion assembly includes a resistance assembly, which is arranged inside the cover plate. The resistance assembly includes a resistance plate, which is slidably connected to the inside of the cover plate. A rack meshing with a spur gear is installed on one side of the upper end of the resistance plate. The bottom end of the resistance plate resists with a locking assembly. A bellows is fixedly connected to one side of the resistance plate. The top of the bellows is fixedly connected to the cover plate, and the top of the bellows is connected to the inside of the first air groove through the second air groove.

[0010] Preferably, outer walls at both ends of the rotating shaft are sleeved with spring sheets, and the rotating shaft is elastically connected to the cover plate via the spring sheets.

[0011] Preferably, a plurality of holes are provided inside the movable plate, and the top of each of the holes is connected to the first air groove.

[0012] Preferably, arc grooves are provided in contact areas between the two sides of the movable plate and the second air groove, and the two sides of the arc groove are respectively connected to the first air groove and the second air groove.

[0013] Preferably, the moving assembly comprises a mounting block, one end of which passes through the cover plate and is fixedly connected to the abutment plate, and the tops of the two mounting blocks are connected as one by a pull rod;

[0014] The cover plate is provided with a slide groove for allowing the mounting block to move vertically, and the top and bottom surfaces of the mounting block are both installed with folding plates for closing the slide groove. The folding plates will ensure that the slide groove for moving the mounting block will not be hollowed out, thereby ensuring the sealing of the interior of the cover plate, and preventing external dust from entering the interior of the cover plate, so that the dust will not hinder the subsequent movement of the internal structure of the cover plate.

[0015] Preferably, a flexible spring is sleeved on the outer wall of the bellows, and the top and bottom ends of the flexible spring are respectively fixed to the cover plate and the back plate. The back plate compresses the bellows upward, allowing the gas inside the bellows to enter the second air groove. At the same time, the flexible spring will be compressed by the upward lifting of the back plate. Conversely, the flexible spring releases its elastic force, causing the back plate to move downward and expand the bellows again.

[0016] Preferably, the backing plate is composed of two parts. The upper part of the backing plate is in an inverted "L" shape, and the lower part of the backing plate is in a "丄" shape. The "L" shape design of the upper part of the backing plate can better support the corrugated pipe. During the upward movement of the backing plate, the gas inside the corrugated pipe can be stably compressed. The "丄" shape design of the lower part of the backing plate can, when the backing plate moves downward, make the two sides of its bottom end squeeze the locking component, thereby causing the locking component to move, and locking the movable plate through the locking component, so that the movable plate will not swing under normal conditions, ensuring the overall stability of the movable plate.

[0017] Preferably, multiple sets of racks are provided. The multiple sets of racks are intermittently installed on the backing plate. When the backing plate moves upward, a section of the rack will mesh with the spur gear through a section of the rack, and the spur gear will drive the rotating shaft to rotate. The rotating shaft will drive the overall turning of the movable plate. As the backing plate moves upward, when the interval area between two sections of the rack corresponds to the spur gear, the interval area is smooth at this time and cannot mesh with the spur gear. The spur gear and the rotating shaft will be elastically reset by the spring piece and turn in the opposite direction. Through the continuous upward movement of the backing plate, the intermittent distribution of multiple racks, and the cooperation of the spring piece, the movable plate will have a reciprocating slight swing.

[0018] Preferably, the locking component includes a baffle plate. The baffle plate is movably connected to the cover plate, and the baffle plate is elastically connected to the inner cavity of the cover plate through a spring telescopic cylinder.

[0019] Preferably, an inclined angle is provided at the contact end of the baffle plate and the backing plate. One end of the baffle plate away from the backing plate is located outside the movable plate. When the backing plate moves downward, it will contact the inclined angle area of the baffle plate through its bottom end, causing the baffle plate to move to the side away from the backing plate and block the outside of the movable plate. The spring telescopic cylinder is in a compressed state. On the contrary, when the backing plate moves upward, the contact with the baffle plate is released, and the compressed spring telescopic cylinder will release elastic force to make the baffle plate move to the side away from the movable plate, so that the movable plate can perform a turning activity.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Through the cooperation of structures such as the first air groove and the corrugated pipe, the present invention improves the cleaning efficiency of the slots on the housing of the monitoring and alarm device through an embedded and movable design on the housing of the monitoring and alarm device. Pulling up the pull rod makes the backing plate move upward to compress the gas inside the corrugated pipe, so that the gas enters the first air groove through the second air groove and the arc groove. Since each hole communicates with the first air groove, the dust and impurities inside the holes on the movable plate can be fully cleaned, and there is no need to disassemble the housing, which saves time and effort.

[0022] The present invention improves the cleaning efficiency by arranging structures such as racks and spring sheets, and then based on the blowing of wind, the reciprocating swinging movement of the movable plate is used. Multiple racks are intermittently meshed with the spur gears, and through the elastic limitation of the spring sheet, the rotating shaft drives the movable plate to swing back and forth on the cover plate, thereby improving the cleaning efficiency of dust and impurities.

[0023] The present invention arranges the coordination of structures such as a locking component, a movable component and a moving component, and changes the original slot hole fixed installation form on the shell into a swingable design. The operation can be completed by just a slight manual pull. The operation can be started by just pulling up the pull rod. When the operation is ended, the elasticity of the flexible spring causes the abutment plate to contact the baffle plate so that the baffle plate blocks the two sides of the movable plate again, thereby greatly improving the applicability and convenience.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 8 As shown, the present invention provides a monitoring and alarm device for a heating heat exchange station, comprising a monitoring and alarm housing 1 and a cover plate 2, and also comprising:

[0035] The movable component 3 is arranged inside the cover plate 2;

[0036] Extrusion components 5, which are installed on both sides of the inner cavity of the cover plate 2, and a moving component 4 is installed on the side away from the moving component 3;

[0037] The movable assembly 3 includes a movable plate 31 and a rotating shaft 34. The movable plate 31 is connected to the cover plate 2 through the rotating shaft 34. A first air groove 32 is provided inside the movable plate 31. A spur gear 35 is installed on the outer wall of the rotating shaft 34 at one end inside the cover plate 2.

[0038] The extrusion assembly 5 includes a resistance assembly 54, which is arranged inside the cover plate 2. The resistance assembly 54 includes a resistance plate 541, which is slidably connected to the inside of the cover plate 2. A rack 542 meshing with the spur gear 35 is installed on one side of the upper end of the resistance plate 541, and the bottom end of the resistance plate 541 resists with a locking assembly 6. A bellows 51 is fixedly connected to one side of the resistance plate 541, and the top of the bellows 51 is fixedly connected to the cover plate 2. The top of the bellows 51 is connected to the inside of the first air groove 32 through the second air groove 52.

[0039] like Figure 2 and Figure 4 As shown, the outer walls of both ends of the rotating shaft 34 are sleeved with spring sheets 36 , and the rotating shaft 34 is elastically connected to the cover plate 2 through the spring sheets 36 .

[0040] like Figure 3 As shown, a plurality of holes are formed inside the movable plate 31 , and the top of each hole is connected to the first air groove 32 .

[0041] The above scheme is adopted: when the monitoring alarm is triggered inside the monitoring alarm shell 1, the sound will be emitted outward through the holes on the movable plate 31. At the same time, the holes are also convenient for heat dissipation of the internal components of the monitoring alarm shell 1. The holes are connected to the first air groove 32, so that the gas inside the first air groove 32 can blow the dust inside each hole, thereby improving the cleanliness of the holes inside the movable plate 31.

[0042] As Figure 2 and Figure 3 shown, arc grooves 33 are provided in the contact areas on both sides of the movable plate 31 and the second air groove 52. Both sides of the arc groove 33 are respectively communicated with the first air groove 32 and the second air groove 52.

[0043] Adopting the above solution: When the corrugated pipe 51 is compressed to make the gas inside it enter the second air groove 52, the gas inside the second air groove 52 will flow into the first air groove 32. Whether the movable plate 31 is swinging or not, the gas inside the second air groove 52 will enter the first air groove 32 through the arc groove 33, and the holes on the movable plate 31 will be blown by the wind through the first air groove 32.

[0044] As Figure 2 and Figure 5 shown, the moving component 4 includes a mounting block 42. One end of the mounting block 42 penetrates through the cover plate 2 and is fixedly connected to the abutting plate 541. The tops of the two mounting blocks 42 are connected into one body by a pull rod 41;

[0045] A sliding groove for the vertical movement of the mounting block 42 is provided on the cover plate 2, and folding plates 43 for closing the sliding groove are installed on the top and bottom surfaces of the mounting block 42.

[0046] Adopting the above solution: Pull up the pull rod 41 to drive the two mounting blocks 42 to move upward synchronously. When the mounting blocks 42 move upward, they will synchronously drive the abutting plate 541 to move upward inside the cover plate 2. At the same time, the folding plates 43 will ensure that the sliding groove for the movement of the mounting blocks 42 will not be hollowed out, thereby ensuring the sealing of the inside of the cover plate 2 and preventing external dust from entering the inside of the cover plate 2, so as to prevent the dust from hindering the movement of the subsequent internal structure of the cover plate 2.

[0047] As Figure 3 , Figure 5 and Figure 8 shown, a flexible spring 53 is sleeved on the outer wall of the corrugated pipe 51, and the top and bottom ends of the flexible spring 53 are respectively fixedly connected to the cover plate 2 and the abutting plate 541.

[0048] Adopting the above solution: The abutting plate 541 moves upward to compress the corrugated pipe 51, making the gas inside the corrugated pipe 51 enter the second air groove 52. At the same time, the flexible spring 53 will be compressed by the upward movement of the abutting plate 541. Conversely, the flexible spring 53 releases elastic force, causing the abutting plate 541 to move downward and making the corrugated pipe 51 expand again.

[0049] As Figure 5 shown, the abutting plate 541 is composed of two parts. The upper part of the abutting plate 541 is in an inverted "L" shape, and the lower part of the abutting plate 541 is in a "丄" shape.

[0050] Adopting the above solution: The "L"-shaped design of the upper end part of the bottom plate 541 can better support the corrugated pipe 51. During the upward movement of the bottom plate 541, the gas inside the corrugated pipe 51 can be stably compressed. The "丄"-shaped design of the lower end of the bottom plate 541 can, when the bottom plate 541 moves downward, cause both sides of its bottom end to squeeze the locking assembly 6, thereby causing the locking assembly 6 to move, and locking the movable plate 31 through the locking assembly 6, so that the movable plate 31 will not swing under normal conditions, ensuring the overall stability of the movable plate 31.

[0051] As Figure 5 and Figure 8 shown, multiple sets of rack bars 542 are provided, and the multiple sets of rack bars 542 are installed on the bottom plate 541 in an intermittent manner.

[0052] Adopting the above solution: When the bottom plate 541 moves upward, it will cause a section of the rack bar 542 to mesh with the spur gear 35 through a section of the rack bar 542, and cause the spur gear 35 to drive the rotating shaft 34 to rotate. Through the rotating shaft 34, the entire movable plate 31 is driven to flip. As the bottom plate 541 moves upward, when the interval area between two sections of the rack bar 542 corresponds to the spur gear 35, at this time, the interval area is smooth and cannot mesh with the spur gear 35. The spur gear 35 and the rotating shaft 34 will be elastically reset by the spring piece 36 and flip in the opposite direction. Through the continuous upward movement of the bottom plate 541, the intermittent distribution of multiple rack bars 542, and the cooperation of the spring piece 36, the movable plate 31 will have a reciprocating slight swing.

[0053] As Figure 5 , Figure 6 and Figure 8 shown, the locking assembly 6 includes a baffle 61, the baffle 61 is movably connected to the cover plate 2, and the baffle 61 is elastically connected to the inner cavity of the cover plate 2 through a spring telescopic cylinder 62.

[0054] As Figure 5 and Figure 6 shown, the contact end of the baffle 61 and the bottom plate 541 is provided with an oblique angle, and the end of the baffle 61 away from the bottom plate 541 is located outside the movable plate 31.

[0055] Adopting the above solution: When the bottom plate 541 moves downward, it will pass through the oblique angle area of the baffle 61 at its bottom end, causing the baffle 61 to move to the side away from the bottom plate 541 and block the outside of the movable plate 31. The spring telescopic cylinder 62 is in a compressed state. On the contrary, when the bottom plate 541 moves upward, the contact with the baffle 61 is released, and the compressed spring telescopic cylinder 62 will release elastic force to make the baffle 61 move to the side away from the movable plate 31, so that the movable plate 31 can perform a flipping movement.

[0056] The working principle and usage process of the present invention:

[0057] First, pull up the pull rod 41, so that it drives the abutment plate 541 to move upward inside the cover plate 2 through the mounting block 42. When the abutment plate 541 moves upward, the bottom end first releases the resistance to the baffle plate 61, and the spring telescopic cylinder 62 releases the elastic force of the baffle plate 61, so that the baffle plate 61 moves away from the movable plate 31, that is, the obstruction to the movable plate 31 is released;

[0058] Then, as the plate 541 continues to move upward, the bellows 51 is compressed, so that the gas inside the bellows 51 passes through the second gas groove 52 and the arc groove 33 and enters the first gas groove 32, so that the wind force blows away the dust and impurities in the holes on the movable plate 31;

[0059] Finally, as the push plate 541 moves upward, it will mesh with the spur gear 35 together with the rack 542, so that the spur gear 35 drives the movable plate 31 to rotate on the cover plate 2 through the rotating shaft 34. Due to the design of multiple racks 542 and the elastic restriction of the spring sheet 36, as the push plate 541 moves upward, the movable plate 31 rotates back and forth inside the cover plate 2. The holes on the movable plate 31 are cleaned through the reciprocating rotation of the movable plate 31 itself and the wind blowing of the first air groove 32. Conversely, the upward pull of the pull rod 41 is released, and the flexible spring 53 provides a downward pulling force to the push plate 541, so that the bottom end of the push plate 541 contacts the oblique area of ​​the baffle 61 again, so that the baffle 61 blocks both sides of the movable plate 31, so as to ensure that the subsequent monitoring and alarm device in the heating and heat exchange station can operate normally and will not be affected. At the same time, only a slight manual pull is required, and there is no need to open and disassemble the device.

[0060] It should be additionally explained that the plurality of racks 542 intermittently mesh with the spur gear 35 upward, which only causes the movable plate 31 to swing back and forth slightly.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
