[0002] In the operation process of the diesel engine, it is very important to accurately and timely acquire the exhaust temperature, which helps to understand the working state of the diesel engine in time and ensure its safe and stable operation. Whether in large diesel engine groups in industrial production or in diesel-powered vehicles in the field of transportation, exhaust temperature data are the key basis for judging the combustion efficiency of the diesel engine, fault warning and performance optimization.

[0003] For the current exhaust temperature acquisition device, the temperature acquisition device of the existing circuit breaker disclosed in patent No. CN107091982B realizes that the sensor is installed in the current transformer and contact-mounted with the busbar through the mounting mode of directly connecting the contact sheet with the busbar, which not only ensures the simplicity and stability of the sensor installation, but also realizes that the contact sheet of the sheet structure can be completely in contact with the surface of the busbar and tightly connected, and the sensor is connected with the controller through the signal line, the signal line and the lead-out line of the electromagnetic assembly are arranged in parallel and are led to the outside of the current transformer at the same time.

[0004] However, under the influence of high-frequency and continuous vibration generated by the operation of the diesel engine, the corrugated rings on the surface of the corrugated hose for line protection and connection are prone to frequent contact and collision, and under the long-term mechanical action, the contact parts of the corrugated rings will gradually wear, deform and even break. Once the corrugated hose is damaged, the internal line will lose protection and be easily eroded and mechanically damaged by the external environment, resulting in interruption or distortion of the exhaust temperature signal transmission.

[0005] Therefore, the present application provides a diesel engine multi-path exhaust temperature acquisition device. SUMMARY

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments.

[0027] Embodiment one:

[0028] Referring to Figures 1-3 A diesel engine multi-path exhaust temperature collector, comprising a diesel engine body 1, a support plate 2 is installed on the diesel engine body 1, a collector interface 3 is installed on the diesel engine body 1, a collector body 4 is installed on the collector interface 3, a pressing part is arranged on the collector interface 3, the pressing part is composed of a pressing piece and a rotating assembly, the pressing piece is used for pressing the collector body 4 and the collector interface 3, and the rotating assembly is used for driving the pressing piece to act.

[0029] The rotating component is installed on the collector body 4 through the collector interface 3. When the rotating component moves, it drives the drive component to operate and simultaneously drives the clamping component to work. When the rotating component drives the clamping component, it can make the clamping component apply pressure to the collector body 4 in four directions along the collector interface 3, and fill the gap between the collector body 4 and the collector interface 3 through this pressure.

[0030] In this embodiment, as Figures 2-3 As shown, the clamping part in this embodiment can be implemented by designing the following structure:

[0031] The rotating assembly comprises a fixed plate 311, an L-shaped rod 31, a rack 32, a rotating rod 33, a gear 34, and a slot 38. The fixed plate 311 is fixedly installed on the side wall of the collector interface 3, and four fixed plates 311 are provided. The interior of the fixed plate 311 is hollow. The L-shaped rod 31 is provided on the side wall of the collector body 4, and four L-shaped rods 31 are provided. The rack 32 is fixedly connected to the bottom end of the L-shaped rod 31. The rotating rod 33 is rotatably connected to the inner wall of the fixed plate 311. The gear 34 is fixedly connected to the rotating rod 33. The gear 34 and the rack 32 mesh with each other. The slot 38 is opened on the top surface of each fixed plate 311. The L-shaped rod 31 and the rack 32 are inserted into the inner wall of the slot 38.

[0032] The clamping components include connecting rods 35, pressure plates 36, and through slots 37. The connecting rods 35 are symmetrically fixedly connected to the rotating rods 33. The pressure plates 36 are fixedly connected to the ends of the two connecting rods 35 away from the rotating rods 33. Each pressure plate 36 has a slot at its front end. After the four pressure plates 36 are flipped over, the slots can be covered to form a sealing plate, preventing dust from entering the inside of the collector interface 3. The through slots 37 are symmetrically opened on the side wall of the fixed plate 311 to provide a position for the rotation of the connecting rods 35.

[0033] In this embodiment, when the collector body 4 is installed, its surrounding L-shaped rods 31 and bottom rack 32 are simultaneously inserted into the four fixing plates 311 through the slots 38. During the movement of the L-shaped rods 31, the rack 32 will contact and mesh with the gear 34. The gear 34 is subjected to force and rotates, driving the rotating rod 33 to rotate. The externally symmetrically fixed connecting rod 35 then flips over from the through slot 37 as the rotating rod 33 rotates. After the collector body 4 is installed and enters the collector interface 3, the connecting rod 35 and the four pressure plates 36 flip to the top surface of the collector interface 3, thereby blocking the connection between the collector interface 3 and the collector body 4. At the same time, the pressure plates 36 will also pressurize the collector body 4 to prevent the collector body 4 from becoming loose when the diesel engine body 1 is working.

[0034] Example 2:

[0035] Reference Figure 2 , Figure 4 ,Figure 5 The collector body 4 is provided with a corrugated hose 5, the corrugated hose 5 is provided with an air cushion 65, the inside of the corrugated hose 5 is provided with a reverse pushing and inflating part, the reverse pushing and inflating part is composed of a reverse pushing piece and an inflating piece, the reverse pushing piece is used for applying pressure between the corrugated rings on the corrugated hose 5 in the reverse direction, the reverse pushing piece and the inflating piece are linked through the vibration generated by the diesel engine body 1, the reverse pushing piece drives the inflating piece to work synchronously when moving reciprocatingly in the inside of the corrugated hose 5, the reverse pushing piece applies reverse pushing force to the corrugated rings on the corrugated hose 5 synchronously when moving reciprocatingly in the inside of the corrugated hose 5, which can promote the adjacent corrugated rings to move away from each other.

[0036] In the embodiment, the reverse pushing and inflating part can be designed as follows:

[0037] The reverse pushing piece is composed of a supporting block 51, a hollow ring 52, a first spring 53, a convex rod 54, a connecting rod 591, a placing block 55, a sliding groove 56, a rotating shaft 57, a rotating rod 58, a convex block 59, a cross rod 510, a resisting block 511 and a second spring 512, the supporting block 51 is symmetrically arranged in the inside of the corrugated hose 5 and fixedly connected with each corrugated ring, the hollow ring 52 is fixedly arranged on the opposite side of the two supporting blocks 51, the strength of each corrugated ring is increased through the hollow ring 52, the two ends of the first spring 53 are arranged on the opposite sides of the two hollow rings 52 respectively, forming an elastic connection structure between the two hollow rings 52, when the supporting block 51 is displaced by external force, the first spring 53 is contracted, and when the supporting block 51 is subjected to reverse external force, the supporting block 51 is driven to return to the initial position, effectively increasing the power and speed of the hollow ring 52 returning to the original position, and the first spring 53 is used to drive the inflating piece to return to the original position synchronously.

[0038] The convex rod 54 is fixedly connected to the side wall of the supporting block 51, the placing block 55 is arranged on the inner wall of the corrugated hose 5, the inside of the placing block 55 is hollow, the sliding groove 56 is arranged at the bottom end of the placing block 55, the rotating shaft 57 is rotatably connected to the inside of the placing block 55, the rotating rod 58 is fixedly connected to the rotating shaft 57, the rotating rod 58 is arranged in the sliding groove 56 and slides in the sliding groove 56, the convex block 59 is fixedly connected to the bottom end of the rotating rod 58, the connecting rod 591 is hingedly connected to the top end of the rotating rod 58, the cross rod 510 is hingedly connected to the end of the connecting rod 591 away from the rotating rod 58, the rotating rod 58 is rotated to drive the cross rod 510 to move reciprocatingly in the placing block 55 through the connecting rod 591, the placing block 55 is provided with a moving groove in which the cross rod 510 slides, the moving track of the cross rod 510 is limited, the cross rod 510 is prevented from deviating or shaking in the movement process, and the cross rod 510 is ensured to move stably along the preset direction.

[0039] The resisting block 511 is fixedly connected to the end of the cross rod 510 away from the connecting rod 591, one end of the second spring 512 is fixedly connected to the side wall of the rotating rod 58, and the other end of the second spring 512 is fixedly connected to the inner wall of the placing block 55.

[0040] In the embodiment, when the diesel engine body 1 works, the high-frequency vibration causes the corrugated hose 5 to contract. In the process of contraction, the inner support block 51 drives the hollow ring 52 to move forward, the side wall of the hollow ring 52 drives the convex rod 54 to move forward, and the convex rod 54 is in contact with the convex block 59 at the front end. The convex block 59 is forced to move with the convex rod 54, and the rotating rod 58 is rotated on the rotating shaft 57, and the second spring 512 is stretched, and the cross plate and the block 511 are pushed forward by the connecting rod 591. When the block 511 is in contact with the support block 51, the support block 51 is pressed by a reverse thrust, so as to drive the support block 51 to move in the opposite direction, and the corrugated ring on the corrugated hose 5 also moves in the opposite direction, thereby reducing the direct impact force between the corrugated rings and avoiding exceeding the bearing range of the corrugated rings.

[0041] Embodiment three:

[0042] Referring to Figure 6 The inflator is used to inflate the air cushion 65. The inflator is driven by the reverse thrust member to inflate the air cushion 65 synchronously, so that the air cushion 65 is inflated, thereby reducing the contact between the corrugated rings.

[0043] In the embodiment, the inflator can be realized by the following specific structure:

[0044] The inflator is composed of a mounting plate 6, a sliding rod 61, a rubber plug 611, an air inlet pipe 62, an air outlet pipe 63, and a shunt pipe 64. The mounting plate 6 is arranged on the inner wall of the corrugated hose 5, and the mounting plate 6 is hollow inside. One end of the sliding rod 61 is slidably connected to the inner wall of the mounting plate 6, and the other end of the sliding rod 61 is fixedly connected to the side wall of the support block 51. The rubber plug 611 is arranged at the top end of the sliding rod 61 and slides in the inner wall of the mounting plate 6. The air inlet pipe 62 is arranged at the front end of the mounting plate 6, the air outlet pipe 63 is arranged at the end of the mounting plate 6, and the shunt pipe 64 is arranged on the air outlet pipe 63. The air inlet pipe 62 and the air outlet pipe 63 are each provided with a one-way valve. The one-way valve in the air inlet pipe 62 only allows fluid to flow from the inlet end to the inner end, and prevents reverse flow. The one-way valve in the air outlet pipe 63 only allows gas to flow from the mounting plate 6 to the outlet end of the air outlet pipe 63, and also prevents reverse flow. The air outlet pipe 63 communicates with the air cushion 65.

[0045] In the present embodiment, when the reverse pushing piece repeatedly moves, the sliding rod 61 on the side wall of the supporting block 51 moves in the mounting plate 6, and the rubber plug 611 on the top thereof moves in the mounting plate 6 simultaneously under the driving of the sliding rod 61. When the sliding rod 61 moves to the air outlet pipe 63, the rubber pad pushes the air in the mounting plate 6 into the air outlet pipe 63, at this time, the one-way valve of the air outlet pipe 63 opens, the gas flows into the air outlet pipe 63, and then enters the air cushion 65 through the shunt pipe 64, inflates the air cushion 65, and makes the corrugated ring surface slightly convex, so that each corrugated ring contacts to reduce the impact force and contact area;

[0046] When the supporting block 51 is reset under the action of the reverse pushing piece and the second spring 512, the sliding rod 61 on the side wall thereof moves to the air inlet pipe 62, at this time, the one-way valve of the air inlet pipe 62 opens, and the one-way valve in the air outlet pipe 63 closes, with the movement of the sliding rod 61, the rubber pad absorbs the air outside into the mounting plate 6 through the air inlet pipe 62, and in this process, the one-way valve in the air inlet pipe 62 opens synchronously to ensure that the air can enter smoothly.

[0047] With the vibration of the diesel engine body 1 driving the continuous operation of the reverse pushing air charging part, the impact force and contact area of the corrugated ring contact on the corrugated hose 5 are reduced, the service life of the corrugated hose 5 is increased, and the damage of the corrugated hose 5 affecting the use of the collector body 4 is avoided.

[0048] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
