Abstract

This utility model discloses a pressure control mechanism for a steam generating device, belonging to the field of steam equipment pressure control. The pressure control mechanism includes a housing with through holes on its left and right side walls. A heat dissipation structure is installed on the housing, and protective structures are installed on the left and right side walls of the housing corresponding to the through holes. The heat dissipation structure includes a dual-axis motor installed on the inner cavity end face of the housing and two sets of rotating rods rotatably installed on the inner cavity side walls of the housing. By setting up the heat dissipation structure, the control flow inside the housing is accelerated, quickly removing heat from the circuit components. This avoids the problem in existing pressure control mechanisms where electronic components generate heat during operation, and the heat cannot be dissipated from the machine in time by relying solely on the pressure control mechanism's own heat dissipation holes, leading to overheating and malfunctions of electronic components.

Description

Technical Field

[0001] This utility model relates to the field of steam equipment pressure control technology, specifically a pressure control mechanism for a steam generating device. Background Technology

[0002] A steam generating device is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The pressure control mechanism stabilizes the steam pressure, ensuring the safe operation of the steam generating device. Steam is generated under high temperature and pressure. If the pressure is too high, exceeding the equipment's tolerance limit, it can damage components of the steam generating device, such as causing pipe ruptures or container explosions. The pressure control mechanism monitors the steam pressure in real time and automatically adjusts the heating power or steam output when the pressure reaches the set value, maintaining stable pressure and preventing safety accidents caused by excessive pressure.

[0003] In existing pressure control mechanisms, the electronic components generate heat during operation. Relying solely on the pressure control mechanism's own heat dissipation vents is insufficient to dissipate this heat from the machine in a timely manner, leading to overheating of the electronic components, causing malfunctions, and affecting their service life.

[0004] Therefore, this utility model provides a pressure control mechanism for a steam generating device to solve the above-mentioned problems. Utility Model Content

[0005] This utility model provides a pressure control mechanism for a steam generating device, aiming to solve the problems mentioned in the background art. When the electronic components in the pressure control mechanism are in use, they generate heat during operation. Relying solely on the heat dissipation holes of the pressure control mechanism itself is insufficient to dissipate the heat from the body in a timely manner, which can lead to excessively high temperatures of the electronic components, causing malfunctions and affecting their service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure control mechanism for a steam generating device, comprising a housing, through holes on the left and right side walls of the housing, a heat dissipation structure installed on the housing, and protective structures installed on the left and right side walls of the housing corresponding to the through holes;

[0007] The heat dissipation structure includes a dual-axis motor mounted on the end face of the housing cavity and two sets of rotating rods rotatably mounted on the side walls of the housing cavity. The drive end of the dual-axis motor is equipped with a first bevel gear, and both ends of the rotating rods are equipped with second bevel gears. The heat dissipation structure also includes two sets of vertical plates mounted on the side walls of the housing cavity. Each vertical plate is rotatably mounted with a shaft via bearings. One end of the shaft, located inside a through-hole, is equipped with fan blades, and the other end is equipped with a third bevel gear. By configuring the heat dissipation structure, the two sets of fan blades rotate within the through-holes on both sides. One set of fan blades blows cool air into the housing, while the other set draws hot air out of the housing, accelerating the control airflow inside the housing, quickly removing heat from the circuit components, protecting the circuit components inside the housing, and extending the service life of the pressure control structure.

[0008] Preferably, the left and right sidewalls of the housing are provided with mounting grooves corresponding to the through holes, and the sidewalls of the housing are provided with sliding grooves on the front and rear sides of the mounting grooves. The protective structure includes a filter screen plate disposed inside the mounting groove, and the protective structure also includes a spring installed inside the sliding groove. A sliding plate is installed at the other end of the spring, a T-shaped plate is installed on the sidewall of the sliding plate, and a handle is installed on the sidewall of the T-shaped plate.

[0009] Preferably, the drive end of the dual-axis motor is equipped with a transmission shaft connected to the first bevel gear, the inner cavity end face of the housing is equipped with a support sleeve that is rotatably connected to the transmission shaft, and the inner cavity side wall of the housing is equipped with two sets of fixing sleeves that are rotatably connected to the outer wall of the rotating rod.

[0010] Preferably, the opening position of the through hole on the left side is higher than that of the through hole on the right side, the length of the rotating rod on the left side is less than that of the rotating rod on the right side, the first bevel gear is meshed with the upper second bevel gear, and the third bevel gear is meshed with the lower second bevel gear.

[0011] Preferably, a mounting plate is bolted to the back of the inner cavity of the housing, circuit components are mounted on the front of the mounting plate, and a pressure signal interface is mounted on the bottom of the housing through a connection hole.

[0012] Preferably, the filter screen is provided with slots on both sides corresponding to the T-shaped plate, and the slots are adapted to fit the T-shaped plate.

[0013] Preferably, the sidewall of the housing is provided with a limiting groove corresponding to the T-shaped plate, and the housing is slidably connected to the T-shaped plate through the limiting groove.

[0014] Beneficial effects: By setting up a heat dissipation structure, two sets of fan blades rotate in the through holes on both sides. One set of fan blades blows cold air into the housing, while the other set of fan blades draws hot air out of the housing. This accelerates the control flow inside the housing and quickly removes heat from the circuit components. This avoids the problem in existing pressure control mechanisms where electronic components generate heat during operation, and the heat cannot be dissipated from the machine in time by relying solely on the heat dissipation holes of the pressure control mechanism itself. This can lead to the electronic components overheating and causing malfunctions. This design protects the circuit components inside the housing and extends the service life of the pressure control structure. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] This embodiment provides a pressure control mechanism for a steam generating device, such as... Figure 1-6 As shown, the pressure control mechanism includes a housing 1, through holes 11 are provided on the left and right side walls of the housing 1, a heat dissipation structure 2 is installed on the housing 1, and a protective structure 3 is installed on the left and right side walls of the housing 1 corresponding to the through holes 11.

[0025] The heat dissipation structure 2 includes a dual-axis motor 21 installed on the inner cavity end face of the housing 1 and two sets of rotating rods 23 rotatably installed on the inner cavity side wall of the housing 1. The driving end of the dual-axis motor 21 is provided with a first bevel gear 22, and the upper and lower ends of the rotating rods 23 are both provided with second bevel gears 24. The heat dissipation structure 2 also includes two sets of vertical plates 25 installed on the inner cavity side wall of the housing 1. The vertical plates 25 are rotatably mounted with a rotating shaft 26 through bearings. One end of the rotating shaft 26 located inside the through hole 11 is provided with a fan blade 27 and a third bevel gear 28 provided at the other end of the rotating shaft 26.

[0026] In use, when the pressure control mechanism is working, the dual-axis motor 21 is started to rotate, driving the transmission shafts 211 at both ends to rotate synchronously. The two sets of transmission shafts 211 drive the corresponding first bevel gears 22 to rotate. The first bevel gears 22 drive the upper second bevel gear 24 to rotate. The upper second bevel gear 24 drives the lower second bevel gear 24 to rotate through the rotating rod 23. The lower second bevel gear 24 drives the third bevel gear 28 to rotate. The third bevel gear 28 drives the rotating shaft 26 to rotate on the vertical plate 25. In turn, the two sets of rotating shafts 26 drive the two sets of fan blades 27 through the corresponding through holes. The 11-stage rotating fan has one set of blades 27 blowing cold air into the housing 1 and another set of blades 27 drawing hot air out of the housing 1, accelerating the control flow inside the housing 1 and quickly removing heat from the circuit components 5. This avoids the problem that in existing pressure control mechanisms, the electronic components generate heat during operation, and the heat cannot be dissipated from the machine in time by relying solely on the heat dissipation holes of the pressure control mechanism itself, which could lead to overheating of the electronic components and malfunctions. This protects the circuit components 5 inside the housing 1 and extends the service life of the pressure control structure.

[0027] In this embodiment, the drive end of the dual-axis motor 21 is equipped with a transmission shaft 211 connected to the first bevel gear 22, and the inner cavity end face of the housing 1 is equipped with a support sleeve 212 rotatably connected to the transmission shaft 211. The inner cavity side wall of the housing 1 is equipped with two sets of fixing sleeves 231 rotatably connected to the outer wall of the rotating rod 23. The opening position of the left through hole 11 is higher than that of the right through hole 11, the length of the left rotating rod 23 is less than that of the right rotating rod 23, the first bevel gear 22 is meshed with the upper second bevel gear 24, and the third bevel gear 28 is meshed with the lower second bevel gear 24.

[0028] Among them, through the setting of support sleeve 212 and fixed sleeve 231, support sleeve 212 can play a stable installation function for transmission shaft 211, ensuring that the first bevel gear 22 and the upper second bevel gear 24 are stably connected together; the two sets of fixed sleeves 231 ensure that the rotating rod 23 is rotatably installed on the side wall of housing 1, so that the rotating rod 23 plays an important transmission role in heat dissipation structure 2.

[0029] In this embodiment, a mounting plate 4 is bolted to the back of the inner cavity of the housing 1, a circuit element 5 is mounted on the front of the mounting plate 4, and a pressure signal interface 6 is mounted on the bottom of the housing 1 through a connection hole.

[0030] Example 2

[0031] Unlike Embodiment 1, the left and right sidewalls of the housing 1 are provided with mounting grooves 12 corresponding to the through holes 11, and the sidewalls of the housing 1 are provided with sliding grooves 13 on the front and rear sides of the mounting grooves 12. The protective structure 3 includes a filter screen plate 31 disposed inside the mounting groove 12. The protective structure 3 also includes a spring 32 disposed inside the sliding groove 13. The other end of the spring 32 is provided with a sliding plate 33. The sidewall of the sliding plate 33 is provided with a T-shaped plate 34. The sidewall of the T-shaped plate 34 is provided with a handle 35.

[0032] During use, due to the opening of the two sets of through holes 11 and the cooperation of the two sets of fan blades 27 to dissipate heat from the inside of the housing 1, dust in the outside air will enter the inside of the housing 1 through the through holes 11 and adhere to the circuit components 5, which may corrode the circuit components 5 or cause short circuits in the circuit components 5. By installing a filter screen plate 31 in the mounting groove 12 on the outside of the through holes 11, the dust entering the housing 1 through the through holes 11 can be filtered and blocked outside the housing 1, thereby ensuring the cleanliness of the air in the housing 1 and protecting the circuit components 5.

[0033] The system includes a slot 311, spring 32, slide plate 33, T-shaped plate 34, and handle 35. When the filter screen 31 becomes clogged after prolonged use, the two sets of handles 35 are driven to move away synchronously. The handles 35 drive the T-shaped plate 34 to move, and the T-shaped plate 34, along with the slide plate 33, compresses the spring 32, thereby causing the T-shaped plate 34 to move out of the slot 311. The filter screen 31 can then be removed for cleaning and replacement. After cleaning or replacement, the filter screen 31 is driven into the mounting slot 12, aligning the slot 311 with the T-shaped plate 34. Then, the handle 35 is released, and under the restoring force of the spring 32, the slide plate 33 pushes the T-shaped plate 34 back into the slot 311 in the limiting groove 14, locking the filter screen 31. This facilitates cleaning, maintenance, or replacement of the filter screen 31, resulting in better dust filtration.

[0034] In this embodiment, slots 311 are provided on both sides of the filter plate 31 and corresponding to the T-shaped plate 34, and the slots 311 and the T-shaped plate 34 are adapted to each other; a limiting groove 14 is provided on the side wall of the housing 1 and corresponding to the T-shaped plate 34, and the housing 1 is slidably connected to the T-shaped plate 34 through the limiting groove 14.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
