Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an engine heat resistance detection device. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is applicable to power generating devices, and can also refer to the entire machine including the power device. During the engine production process, it is necessary to use a heat resistance testing device to test the heat resistance of the engine.

[0003] As disclosed in Chinese patent: Aircraft engine blade detection device, application number: CN202321737625.7, comprising: a console, a control panel is fixedly connected to the top of the console, and a switch is provided on one side of the control panel. The aircraft engine blade detection device places the aircraft engine blade in a rotating test component and turns on the heat control component to perform a rotation test on the aircraft engine blade to be tested. During the rotation test, the heat control component will heat up the inside of the test box, and continue to rotate for a period of time after reaching the maximum ambient temperature that the aircraft generator can reach. The user can observe and inspect the inside of the test box at any time through the content transmitted to the display screen by the heat-resistant camera, and can more intuitively feel whether the aircraft generator blade is deformed. The observation of the detection effect is more obvious, which improves the accuracy and detection range of the device and further improves the work efficiency of the staff.

[0004] However, in the above technical solution, when using the heat resistance testing device to test the heat resistance of the engine, the engine needs to be heated up, so a higher temperature is usually generated inside the heat resistance testing device. At this time, if the engine needs to be taken out, the inside of the heat resistance testing device needs to be cooled down first, and then the engine can be taken out. However, with the long-term use of the heat resistance testing device, the cooling system inside the heat resistance testing device may suddenly fail, resulting in a large amount of heat remaining inside the heat resistance testing device. At this time, if the staff opens the heat resistance testing device, the heat will be converted into heat and dumped to the outlet, causing harm to the staff. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The main purpose of the utility model is to provide an engine heat resistance detection device, which can effectively solve the background technology. When using the heat resistance detection device to perform heat resistance detection on the engine, the engine needs to be heated up, so a higher temperature is usually generated inside the heat resistance detection device. At this time, if the engine needs to be taken out, the inside of the heat resistance detection device needs to be cooled down first, and then the engine can be taken out. However, with the long-term use of the heat resistance detection device, the cooling system inside the heat resistance detection device may suddenly fail, resulting in a large amount of heat remaining inside the heat resistance detection device. At this time, if the staff opens the heat resistance detection device, the heat will be converted into heat and dumped to the outlet, causing harm to the staff.

[0007] (II) Technical solution

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] An engine heat resistance detection device comprises a base, wherein a heat resistance detection chamber and an inlet and outlet passage are arranged on the base, a hot air protection mechanism is arranged on one side of the inlet and outlet passage, a closed baffle door is arranged on one side of the hot air protection mechanism, a slide groove and a groove are arranged on the inner walls on both sides of the inlet and outlet passage respectively, a first sliding baffle door is arranged in the slide groove, a second sliding baffle door is arranged in the groove, a negative pressure heat absorber is arranged in the base, and a heat dissipation outlet is arranged on one side of the base.

[0010] Preferably, the groove is closed by a second sliding door, and both ends of the negative pressure heat absorber are connected to the groove and the heat dissipation outlet respectively.

[0011] Preferably, the hot air protection mechanism comprises a mechanism base, a through slot is provided on the mechanism base, a rotating baffle is provided in the through slot, a rotating baffle is provided on the rotating baffle, and a rotating column is provided on the rotating column. A torsion spring is provided on the rotating column.

[0012] Preferably, a baffle is provided on the inner wall surface of one side of the through slot, an arc-shaped sealing plate is provided between the baffle and the rotating baffle door, an extrusion sensor is provided on the side of the baffle close to the arc-shaped sealing plate, a rangefinder is provided on the arc-shaped sealing plate, and alarms are provided on the inner walls on both sides of the through slot.

[0013] Preferably, the through groove and the inlet and outlet channels are interconnected.

[0014] Preferably, the baffle is located on a side of the through slot away from the rotating column.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) When the engine needs to be taken out, the utility model opens the closed baffle door and releases the sealing of the inlet and outlet passage by the first sliding baffle door. Then, the heat wave in the heat-resistant test chamber moves toward the rotating baffle door through the inlet and outlet passage. At this time, a part of the heat wave is absorbed by the negative pressure heat absorber, and the remaining heat wave squeezes the rotating baffle door. When the heat wave remaining in the heat-resistant test chamber is too large to cause the rotating baffle door to contact the baffle plate, the baffle plate is used to block the rotating baffle door to prevent the heat wave from breaking through the rotating baffle door and entering the closed baffle door. At the same time, the baffle plate will squeeze the squeezing sensor, and then the alarm will sound an alarm to prevent the staff from accidentally pushing open the rotating baffle door, causing the heat wave to cause harm to the staff, thereby protecting the safety of the staff.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2As shown, an engine heat resistance detection device includes a base 1, on which a heat resistance detection chamber 2 and an inlet and outlet channel 3 are arranged, a hot air protection mechanism 4 is arranged on one side of the inlet and outlet channel 3, a closed baffle 5 is arranged on one side of the hot air protection mechanism 4, a slide groove 6 and a groove 7 are respectively arranged on the inner walls on both sides of the inlet and outlet channel 3, a first sliding baffle 8 is arranged in the slide groove 6, and a second sliding baffle 9 is arranged in the groove 7, a negative pressure heat absorber 10 is arranged in the base 1, and a heat dissipation outlet 11 is arranged on one side of the base 1.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the hot air protection mechanism 4 includes a mechanism base 401, a through slot 402 is provided on the mechanism base 401, a rotating baffle 403 is provided in the through slot 402, a rotating column 404 is provided on the rotating baffle 403, and a torsion spring 405 is provided on the rotating column 404;

[0025] A baffle 406 is provided on the inner wall surface of one side of the through slot 402, an arc-shaped sealing plate 407 is provided between the baffle 406 and the rotating baffle door 403, an extrusion sensor 408 is provided on the side of the baffle 406 close to the arc-shaped sealing plate 407, a rangefinder 409 is provided on the arc-shaped sealing plate 407, and alarms 4010 are provided on the inner walls of both sides of the through slot 402. When it is necessary to open the closed baffle door 5, the first sliding baffle door 8 is first released from the sealing of the inlet and outlet channel 3, and then the heat wave in the heat-resistant testing chamber 2 moves toward the rotating baffle door 403 through the inlet and outlet channel 3. At this time, a part of the heat wave is absorbed by the negative pressure heat absorber 10, and the remaining heat wave squeezes the rotating baffle door 403, so that the rotating baffle door 403 rotates around the rotating column 404, and the torsion spring 405 contracts. The arc-shaped sealing plate 407 is used to seal the rotating baffle door 403 during its rotation to prevent the heat wave from accidentally flowing out. At the same time, the rotation distance of the arc-shaped sealing plate 407 is monitored by the rangefinder 409. As the rotation distance of the arc-shaped sealing plate 407 increases, the absorption strength of the negative pressure heat absorber 10 for the heat wave will gradually increase, saving energy. If the heat wave is too large, when the residual heat wave in the heat-resistant test chamber 2 is too large to make the rotating baffle door 403 contact with the baffle 406, the baffle 406 is used to block the rotating baffle door 403 to prevent the heat wave from breaking through the rotating baffle door 403 and entering the closed baffle door 5. At the same time, the baffle 406 will squeeze the squeezing sensor 408, and then the alarm 4010 will sound an alarm to prevent the staff from accidentally pushing open the rotating baffle door 403, causing the heat wave to cause harm to the staff.

[0026] The working principle of this engine heat resistance testing device:

[0027] When in use, first put the engine into the heat resistance test chamber 2, then start the first sliding baffle door 8, close the closed baffle door 5, and use the first sliding baffle door 8 to close the inlet and outlet channel 3, and then the heat resistance test can be carried out. After the test is completed, release the second sliding baffle door 9 from closing the groove 7, and start the negative pressure heat absorber 10 at the same time, and use the negative pressure heat absorber 10 to dissipate heat inside the heat resistance test chamber 2. When the engine needs to be taken out, open the closed baffle door 5 and release the first sliding baffle door 8 from closing the inlet and outlet channel 3. Then the heat wave in the heat resistance test chamber 2 moves to the rotating baffle door 403 through the inlet and outlet channel 3. At this time, part of the heat wave is absorbed by the negative pressure heat absorber 10, and the remaining heat wave squeezes the rotating baffle door 403, so that the rotating The baffle door 403 rotates around the rotating column 404, and the rotation distance of the arc sealing plate 407 is monitored by the rangefinder 409. As the rotation distance of the arc sealing plate 407 increases, the absorption strength of the negative pressure heat absorber 10 for the heat wave will gradually increase. When the heat wave remaining in the heat resistance test chamber 2 is too large and causes the rotating baffle door 403 to contact the baffle plate 406, the baffle plate 406 is used to block the rotating baffle door 403 to prevent the heat wave from breaking through the rotating baffle door 403 and entering the closed baffle door 5. At the same time, the baffle plate 406 will squeeze the squeezing sensor 408, and then the alarm 4010 will sound an alarm to prevent the staff from accidentally pushing open the rotating baffle door 403, causing the heat wave to cause harm to the staff, thereby protecting the safety of the staff.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
