Description

Technical Field

[0001] This utility model relates to the field of wireless temperature measurement technology, specifically an intelligent wireless temperature measurement device. Background Technology

[0002] Existing electrical cabinets are prone to dust accumulation during use, which can affect their internal electrical and heat dissipation performance. As dust accumulates, the heat dissipation performance inside the cabinet decreases. When the cabinet is overloaded and the temperature rises, its inherent heat dissipation performance is insufficient to meet the sudden increase in temperature. Combined with the reduced heat dissipation performance due to dust accumulation, this can easily lead to overheating and damage inside the electrical cabinet.

[0003] Therefore, this utility model provides an intelligent wireless temperature measurement device to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the inside of the electrical cabinet is prone to overheating and damage due to a sudden increase in temperature.

[0005] This utility model provides the following technical solution: an intelligent wireless temperature measurement device, including a housing, a temperature measurement component and a graded heat dissipation component. An air inlet and an air outlet are respectively opened on the opposite sides of the housing. A graded heat dissipation component is fixedly installed near the air inlet. An exhaust fan blade is fixedly installed at the air outlet. Temperature measurement components are fixedly installed at intervals on the air outlet side facing the air inlet.

[0006] The temperature measuring component includes a partition, a crossbar, and a temperature measuring body. The partition is fixedly installed at intervals from the air outlet to the air inlet. The partition has a ventilation opening. The crossbar is installed at a height inside the ventilation opening. The temperature measuring body is fixedly installed on the crossbar.

[0007] The graded heat dissipation assembly includes a drive motor, a crank-connecting rod assembly, a slider, a conductor, a mounting bracket, and an intake fan. The drive motor is fixedly installed at the lower side of the housing, and the crank-connecting rod assembly is fixedly installed at the end of the drive motor. The housing has a sliding groove on the side of the air inlet, and a slider is slidably installed in the sliding groove. The other end of the crank-connecting rod assembly is hinged to the slider. Conductors are fixedly installed on the opposite sides of the slider and the sliding groove. Mounting brackets are fixedly installed at intervals on the side of the air inlet facing the air outlet, and an intake fan is fixedly installed on the side of the mounting bracket away from the air inlet.

[0008] The crank-connecting rod assembly includes a wheel body and a connecting rod. The output shaft of the drive motor is fixedly mounted with the wheel body. The connecting rod is hinged to the eccentric part of the wheel body surface. An extension block is fixedly mounted on the surface of the sliding body. The other end of the connecting rod is hinged to the extension block.

[0009] The conductor includes a first conductor and a second conductor. The first conductor is fixedly installed on the surface of the sliding body, and the second conductor is fixedly installed on the surface of the sliding groove near the first conductor.

[0010] The air inlet includes an upper air inlet and a lower air inlet. The air intake fan is arranged in two sets vertically corresponding to the upper air inlet and the lower air inlet. The first conductor and the second conductor are arranged in two sets vertically corresponding to the upper air inlet and the lower air inlet.

[0011] A brush is fixedly installed on the side of the sliding body near the air inlet.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention keeps the electrical cabinet closed when not in use, preventing external air from entering and affecting its electrical performance. When the electrical cabinet is in use, the lower air inlet is opened and the lower air intake fan is activated, allowing external cold air to cool the internal components of the electrical cabinet before being expelled through the temperature sensing component. The temperature sensing component can comprehensively detect the air expelled from the electrical cabinet and use the overall temperature of the expelled air to detect the overall temperature inside the electrical cabinet. Based on the overall temperature inside the electrical cabinet, the two sets of air inlets and air intake fan are activated, enabling temperature-graded cooling. This prevents dust from entering while ensuring a stable temperature inside the electrical cabinet and preventing overheating. Furthermore, the mesh structure mounting bracket, in conjunction with the air inlet, provides multiple filtrations, further preventing external dust from entering. Attached Figure Description

[0028] In view of the technical problem that existing electrical cabinets are prone to overheating and damage due to sudden temperature rise, this disclosure provides an intelligent wireless temperature measurement device, including a housing 1, a temperature measurement component 2, and a graded heat dissipation component 3. The housing 1 has an air inlet 11 and an air outlet 12 on opposite sides. The graded heat dissipation component 3 is fixedly installed near the air inlet 11. An exhaust fan blade is fixedly installed at the air outlet 12. The temperature measurement component 2 is fixedly installed at intervals on the air outlet 12 facing the air inlet 11.

[0029] The temperature measuring component 2 includes a partition 21, a crossbar 22, and a temperature measuring body 23. The partition 21 is fixedly installed at intervals from the air outlet 12 to the air inlet 11. A ventilation opening 211 is opened in the partition 21. A crossbar 22 is installed at a height in the ventilation opening 211. The temperature measuring body 23 is fixedly installed on the crossbar 22.

[0030] It should be noted that both the air inlet 11 and the air outlet 12 are fixed with filters by bolts to prevent external dust from entering.

[0031] It should be noted that the temperature measuring body 23 can be any device or structure in the prior art that can detect temperature. The device or structure for detecting temperature is a very mature technology in the prior art, and will not be elaborated on here.

[0032] It should be noted that when air enters the electrical cabinet for heat exchange, if there is localized overheating inside the electrical cabinet, the overall temperature of the air after heat exchange will increase.

[0033] During use, air enters through the air inlet 11 of the enclosure 1 via the graded heat dissipation assembly 3. The air then undergoes heat exchange and cooling through the internal components of the electrical cabinet. The cooled air then flows towards the temperature measuring assembly 2, enters through the vent 211, and comes into contact with the temperature measuring element 23. The temperature of the cooled air is measured by the temperature measuring element 23, and the overall temperature inside the electrical cabinet is determined based on this overall temperature. Finally, the cooled air is discharged through the air outlet 12 of the enclosure 1 after passing through the vent 211 and the temperature measuring element 23.

[0034] The graded heat dissipation assembly 3 includes a drive motor 31, a crank-connecting rod assembly 32, a slider 33, a conductor 34, a mounting bracket 35, and an intake fan 36. The drive motor 31 is fixedly installed at the lower side of the air outlet 12. The crank-connecting rod assembly 32 is fixedly installed at the end of the drive motor 31. The air outlet 1 has a groove 13 on the side of the air inlet 11. The slider 33 is slidably installed in the groove 13. The other end of the crank-connecting rod assembly 32 is hinged to the slider 33. The conductor 34 is fixedly installed on the opposite side of the slider 33 and the groove 13. The mounting bracket 35 is fixedly installed at intervals on the side of the air inlet 11 toward the air outlet 12. The intake fan 36 is fixedly installed on the side of the mounting bracket 35 away from the air inlet 11.

[0035] The crank-connecting rod assembly 32 includes a wheel body 321 and a connecting rod 322. The output shaft of the drive motor 31 is fixedly mounted with the wheel body 321. The connecting rod 322 is hinged to the eccentric part of the surface of the wheel body 321. The surface of the sliding body 33 is fixedly mounted with an extension block 331. The other end of the connecting rod 322 is hinged to the extension block 331.

[0036] The conductor 34 includes a first conductor 341 and a second conductor 342. The first conductor 341 is fixedly installed on the surface of the sliding body 33, and the second conductor 342 is fixedly installed on the surface of the sliding groove 13 near the first conductor 341.

[0037] It should be noted that the drive motor 31 in this embodiment is a stepper motor or a servo motor, thereby enabling precise control of the rotation angle and reverse reset. Furthermore, in addition to reverse reset, the drive motor 31 in this embodiment can also be reset by setting a rotation angle to maintain unidirectional rotation.

[0038] When the electrical cabinet is in use, the drive motor 31 starts and drives the wheel 321 to rotate, thereby causing the end of the connecting rod 322 to swing and push the sliding body 33 upward. This causes the sliding body 33 to move upward in the slide groove 13, opening the air inlet 11 of the cabinet 1. During the upward movement of the sliding body 33, the first conductor 341 on the surface of the sliding body 33 will contact the second conductor 342 in the slide groove 13, thereby starting the air intake fan 36 to work. Then, the air intake fan 36 inputs external cold air into the electrical cabinet for heat exchange and cooling.

[0039] It should be noted that when the electrical cabinet is not in operation under normal conditions, the sliding body 33 closes the air inlet 11 on the surface of the cabinet 1, thereby reducing dust entry when not in use. This helps maintain the cleanliness of the electrical cabinet and prevents excessive dust accumulation from reducing the electrical performance of the internal components. It should also be noted that in this embodiment, when not in use, the air outlet can be shielded by any existing structure, such as a cover or dustproof cloth, thereby reducing dust entry and further maintaining the cleanliness of the electrical cabinet.

[0040] It should be noted that the mounting bracket 35 in this embodiment adopts a mesh plate, which can accommodate air circulation and cooling while working with the filter at the air inlet 11 to achieve secondary filtration, further preventing external dust from entering.

[0041] The air inlet 11 includes an upper air inlet 111 and a lower air inlet 112. The air intake fan 36 is arranged in two sets vertically corresponding to the upper air inlet 111 and the lower air inlet 112. The first conductor 341 and the second conductor 342 are arranged in two sets vertically corresponding to the upper air inlet 111 and the lower air inlet 112.

[0042] When the electrical cabinet is in use, the drive motor 31 starts and drives the wheel 321 to rotate 90°. This causes the end of the connecting rod 322 to swing and push the sliding body 33 upward, thereby causing the sliding body 33 to move upward in the slide groove 13 and open the lower air inlet 112 of the cabinet 1. During the upward movement of the sliding body 33, the first conductor 341 on the upper surface of the sliding body 33 will contact the second conductor 342 on the lower side of the slide groove 13, thereby activating the intake fan 36 located on the lower side corresponding to the lower air inlet 112. This allows external cold air to be introduced into the electrical cabinet for heat exchange and cooling through the lower air inlet 112 and the lower intake fan 36.

[0043] When external cold air exchanges heat with the electrical cabinet through the lower air inlet 112 and the lower air intake fan 36 and enters the ventilation port 211 to come into contact with the temperature measuring body 23, when the temperature measuring body 23 detects that the overall temperature in the electrical cabinet is too high, it restarts the drive motor 31 and drives the wheel 321 to rotate 90° again. This causes the end of the connecting rod 322 to swing through the wheel 321 and push the sliding body 33 to move upward again, so that the sliding body 33 moves upward in the slide groove 13 and opens the upper air inlet 111 of the box 1. During the upward movement of the sliding body 33, the first conductor 341 on the upper surface of the sliding body 33 disengages from the second conductor 342 on the lower side of the slide groove 13 and comes into contact with the second conductor 342 on the upper side of the slide groove 13. Then, the first conductor 341 on the lower surface of the sliding body 33 comes into contact with the second conductor 342 on the lower side of the slide groove 13 and is energized, thereby simultaneously activating the upper and lower sets of air intake fan blades 36. This enhances the heat exchange and cooling effect on the electrical cabinet by simultaneously opening the upper air intake 111 and the lower air intake 112 in conjunction with the activated two sets of air intake fan blades 36. This helps to adjust the cooling effect according to the working temperature inside the electrical cabinet while preventing dust from entering. It also helps to prevent the internal temperature of the electrical cabinet from becoming too high and maintain the stable working temperature of the electrical cabinet while reducing dust entry.

[0044] It should be noted that the temperature measuring body 23 can control the drive motor 31 to start rotating 90° according to the microcontroller and the written program code in the prior art. Controlling the rotation angle of the drive motor 31 according to the temperature is a very mature technology in the prior art, and the principle and structure will not be described in detail here.

[0045] A brush 37 is fixedly installed on the side of the sliding body 33 near the air inlet 11. During the movement of the sliding body 33, the brush 37 can also clean the filter screen at the air inlet 11, thereby preventing the filter screen at the air inlet 11 from becoming clogged and helping to ensure the efficiency of heat dissipation and ventilation.

[0046] The working process of this embodiment of the disclosure:

[0047] When the electrical cabinet is not in operation, the sliding body 33 closes the air inlet 11 on the surface of the cabinet 1, thereby preventing dust from entering when not in use. This helps to keep the electrical cabinet clean and prevents dust accumulation from reducing the electrical performance of the internal components of the electrical cabinet.

[0048] When the electrical cabinet is in use, the drive motor 31 starts and drives the wheel 321 to rotate 90°. This causes the end of the connecting rod 322 to swing and push the sliding body 33 upward, thereby causing the sliding body 33 to move upward in the slide groove 13 and open the lower air inlet 112 of the cabinet 1. During the upward movement of the sliding body 33, the first conductor 341 on the upper surface of the sliding body 33 will contact the second conductor 342 on the lower side of the slide groove 13, thereby activating the intake fan 36 located on the lower side corresponding to the lower air inlet 112. This allows external cold air to be introduced into the electrical cabinet for heat exchange and cooling through the lower air inlet 112 and the lower intake fan 36.

[0049] When external cold air exchanges heat with the electrical cabinet through the lower air inlet 112 and the lower air intake fan 36 and enters the ventilation port 211 to come into contact with the temperature measuring body 23, when the temperature measuring body 23 detects that the overall temperature in the electrical cabinet is too high, it restarts the drive motor 31 and drives the wheel 321 to rotate 90° again. This causes the end of the connecting rod 322 to swing through the wheel 321 and push the sliding body 33 to move upward again, so that the sliding body 33 moves upward in the slide groove 13 and opens the upper air inlet 111 of the box 1. During the upward movement of the sliding body 33, the first conductor 341 on the upper surface of the sliding body 33 disengages from the second conductor 342 on the lower side of the slide groove 13 and comes into contact with the second conductor 342 on the upper side of the slide groove 13. Then, the first conductor 341 on the lower surface of the sliding body 33 comes into contact with the second conductor 342 on the lower side of the slide groove 13 and is energized, thereby simultaneously activating the upper and lower sets of air intake fan blades 36. This enhances the heat exchange and cooling effect on the electrical cabinet by simultaneously opening the upper air intake 111 and the lower air intake 112 in conjunction with the activated two sets of air intake fan blades 36. This helps to adjust the cooling effect according to the working temperature inside the electrical cabinet while preventing dust from entering. It also helps to prevent the internal temperature of the electrical cabinet from becoming too high and maintain the stable working temperature of the electrical cabinet while reducing dust entry.
