Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, specifically an integrated explosion-proof mechanical temperature controller. Background Technology

[0002] A temperature controller is an automatic control device that maintains a stable target temperature by monitoring the temperature, comparing it with a preset value, and driving an actuator. It is widely used in home appliances, industrial production, laboratory equipment, and other scenarios.

[0003] The prior art CN221670173U discloses an integrated explosion-proof temperature controller, including a mounting plate, an explosion-proof temperature controller body, and a temperature measuring unit located at the bottom of the explosion-proof temperature controller body for detecting temperature. The explosion-proof temperature controller body has heat dissipation windows on both the upper and lower sides inside, and heat dissipation fans are provided at the heat dissipation windows for heat dissipation. The front end of the explosion-proof temperature controller body is connected to the front cover through a fixing mechanism. The fixing mechanism includes fixing rods located at the four corners of the front cover for inserting into fixing slots. The vertical part of the C-shaped fixing plate is inserted into the inside of the fixing rod. The center of the C-shaped fixing plate has a screw rod that is threadedly connected to the explosion-proof temperature controller body. The front cover and the explosion-proof temperature controller body are fixed by the screw rod and the C-shaped fixing plate.

[0004] However, the following shortcomings still exist in actual use: the front cover is fixed by screw two, which requires the corresponding tools for disassembly and assembly, making the operation cumbersome. In humid or corrosive environments, screw two is prone to rust and jamming, further increasing the difficulty of disassembly. The device dissipates heat through heat dissipation windows and cooling fans, which can meet the normal heat dissipation needs. However, when the temperature inside the thermostat rises sharply or even catches fire due to short circuits, component aging or other faults, the heat dissipation windows become a channel for the spread of flames and high-temperature gases, making it impossible to suppress the internal fire and easily causing the fire to spread, posing a serious safety hazard.

[0005] Based on this, an integrated explosion-proof mechanical temperature controller is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide an integrated explosion-proof mechanical temperature controller to solve the problems in the background art.

The rotating box contains a bevel gear one, which is driven by a motor. The motor is fixedly connected to the rotating box. The bevel gear one meshes with multiple bevel gears two, which are fixedly connected to a rotating shaft. The rotating shaft is rotatably connected to the rotating box. One end of the rotating shaft extends out of the rotating box and is rotatably connected to the inner wall of the heat dissipation hole. The outer end of the rotating shaft is provided with sealing blades.

[0012] In one alternative embodiment: the fire extinguishing component includes a pressure bottle located in a mounting box on the side of the explosion-proof housing.

[0016] In one alternative: the sealing cap is provided with a sealing ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model, through the setting of a fixing mechanism, uses a pressing block linked to a traction rope to simultaneously pull four locking blocks out of the slot, quickly completing the disassembly of the sealing cover; during installation, only the sealing cover needs to be fastened, and the spring automatically pushes the locking blocks to reset and lock, requiring no auxiliary tools, thus improving operational efficiency; when the temperature is abnormal, the sealing component at the heat dissipation hole is driven by a motor to rotate and close the sealing blade, blocking the heat dissipation hole, preventing the leakage of flames and high-temperature gases, and avoiding the spread of fire; when the internal temperature of the fire extinguishing component exceeds a preset threshold, inert gas is injected into the explosion-proof housing for explosion-proof treatment.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-7 As shown, an integrated explosion-proof mechanical temperature controller includes an explosion-proof housing 100, a temperature controller body 200 housed within the housing 100, a temperature probe 201 for detecting temperature at the bottom of the body 200 extending out of the housing 100, a sealing cover 101 connected to the front end of the housing 100 via a fixing mechanism, heat dissipation holes 102 on the upper and lower sides of the housing 100, cooling fans 103 at the holes 102, and sealing components at the holes 102. The side is equipped with a fire extinguishing component. The thermostat body 200 is connected to external equipment. The temperature is detected by the temperature probe 201. The thermostat body 200 controls the operation of the equipment. Under normal working conditions, the heat dissipation hole 102 is open, and the cooling fan 103 dissipates heat from the inside of the explosion-proof housing 100. When the temperature inside the thermostat rises sharply or even catches fire due to faults such as short circuit or component aging, the sealing component seals the heat dissipation hole 102. The fire extinguishing component prevents the fire from spreading inside the explosion-proof housing 100. The fixing mechanism facilitates the installation and removal of the sealing cover, improving operating efficiency.

[0029] In this embodiment, as Figure 2 and Figure 3As shown, the fixing mechanism includes four movable slots 301, which are disposed on the explosion-proof housing 100. Sliding blocks 302 are connected to the four movable slots 301. The sealing cover 101 has slots 303 that cooperate with the slots 302. Springs 304 are disposed in each movable slot 301, with both ends of the springs 304 connected to the slots 302 and the movable slots 301 respectively. A through hole 305 is provided between two movable slots 301, and a traction rope 306 is disposed in the through hole 305. Both ends of the traction rope 306 are connected to two slots 302 respectively. A pressing groove 307 is provided in the middle of the through hole 305, in which a sliding... The connecting pressing block 308 is used, and the traction rope 306 passes through the pressing block 308. When the sealing cover 101 is closed on the front end of the explosion-proof housing 100, the locking block 302 can be locked into the corresponding locking groove 303 to fix the sealing cover 101 to the explosion-proof housing 100. At this time, the traction rope 306 is in a taut state. When it is necessary to remove the sealing cover 101, the pressing block 308 is pressed, and the pressing block 308 generates a downward pulling force on the traction rope 306. The traction rope 306 pulls the locking blocks 302 at both ends to slide away from the locking groove 303 and compresses the spring 304, so that the locking blocks 302 are disengaged from the locking groove 303, thereby realizing the quick removal of the sealing cover 101 without the need for any tools, which is convenient to operate.

[0030] In one embodiment, such as Figure 5 , Figure 6 and Figure 7 As shown, the sealing component includes a rotating box 401, which is fixedly connected to the heat dissipation hole 102 via a fixing bracket. A bevel gear 402 is disposed within the rotating box 401 and is driven by a motor 403, which is fixedly connected to the rotating box 401. The bevel gear 402 meshes with multiple bevel gears 404, which are fixedly connected to a rotating shaft 405. The rotating shaft 405 is rotatably connected to the rotating box 401. One end of the rotating shaft 405 extends out of the rotating box 401 and is rotatably connected to the inner wall of the heat dissipation hole 102. The outer end of the rotating shaft 405 is provided with sealing blades 406. When the temperature inside the thermostat rises sharply or even catches fire due to faults such as short circuit or component aging, the motor 403 is started. The motor 403 drives the first bevel gear 402 to rotate, the first bevel gear 402 drives the second bevel gear 404 to rotate, the second bevel gear 404 drives the rotating shaft 405, and the rotating shaft 405 drives the sealing blades 406 to rotate. Multiple sealing blades 406 seal the heat dissipation hole 102.

[0031] In one embodiment, such as Figure 4As shown, the fire extinguishing component includes a pressure cylinder 501, which is located in a mounting box 502 on the side of the explosion-proof housing 100. A solenoid valve 503 is provided at the outlet of the pressure cylinder 501, connected to a gas outlet pipe 504 that extends into the explosion-proof housing 100. A one-way valve 505 is provided on the explosion-proof housing 100. The solenoid valve 503 is electrically connected to a controller 506, which is electrically connected to a thermometer 507. The thermometer 507 is fixedly connected to the explosion-proof housing 100. When the thermometer 507 detects that the internal temperature exceeds a preset threshold, the controller 506 controls the solenoid valve 503 to open, releasing the high-pressure inert gas in the pressure cylinder 501 for explosion-proof treatment.

[0032] In one embodiment, such as Figure 4 As shown, a drying frame 601 is provided on the side of the explosion-proof housing 100 near the one-way valve 505. The drying frame 601 is connected to the heat dissipation hole 102. A desiccant is provided in the drying frame 601. The drying frame 601 is provided with a vent hole 602. The desiccant can absorb moisture in the air, prevent humid air from entering the interior of the explosion-proof housing 100, and prevent the internal electronic components from being damaged by moisture.

[0033] In one embodiment, such as Figure 4 As shown, the outer end of the temperature probe 201 is fitted with a waterproof sleeve 700, which can effectively prevent water or other liquids from seeping into the interior of the temperature probe 201, avoid damage to the temperature probe 201 due to water ingress, and ensure the normal operation of the temperature detection function. It is especially suitable for humid environments or environments that may come into contact with liquids.

[0034] In one embodiment, such as Figure 2 As shown, the four movable slots 301 are evenly distributed on the explosion-proof housing 100.

[0035] In one embodiment, such as Figure 5 As shown, the sealing cover 101 is provided with a sealing ring 800. The sealing ring 800 is squeezed between the two to fill the gap, which not only enhances the sealing performance of the device and prevents dust, moisture and other impurities from entering the explosion-proof housing 100, but also further improves the explosion-proof effect of the device.

[0036] The above embodiment discloses an integrated explosion-proof mechanical temperature controller, wherein the temperature controller body 200 is connected to external equipment, and the temperature is detected by the temperature probe 201. The temperature controller body 200 controls the operation of the equipment. Under normal working conditions, the heat dissipation hole 102 is open, and the cooling fan 103 dissipates heat from the inside of the explosion-proof housing 100. When the temperature inside the temperature controller rises sharply or even catches fire due to faults such as short circuit or component aging, the motor 403 is started. The motor 403 drives the first bevel gear 402 to rotate, the first bevel gear 402 drives the second bevel gear 404 to rotate, the second bevel gear 404 drives the rotating shaft 405, and the rotating shaft 405 drives the sealing blades 406 to rotate. The multiple sealing blades 406 seal the heat dissipation hole 102. The controller 506 controls the solenoid valve 503 to open, releasing the high-pressure inert gas in the pressure bottle 501 for explosion-proof treatment. When the sealing cap 101 is closed on the front end of the explosion-proof housing 100, the locking block 302 can be locked into the corresponding slot 303 to fix the sealing cap 101 to the explosion-proof housing 100. At this time, the traction rope 306 is in a taut state. When it is necessary to remove the sealing cap 101, press the pressing block 308. The pressing block 308 generates a downward pulling force on the traction rope 306. The traction rope 306 pulls the locking blocks 302 at both ends to slide away from the slot 303 and compresses the spring 304, causing the locking blocks 302 to disengage from the slot 303, thereby realizing the quick removal of the sealing cap 101 without the need for any tools, making the operation convenient.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
