DETAILED DESCRIPTION

[0029] The drawings are described below Figures 1-5 The present application is further described in detail.

[0030] The embodiment of the present application discloses a multifunctional audio and video integrated conference machine.

[0031] Referring to Figures 1-3 The first temperature sensor 2 is used for monitoring the temperature in the machine body 1, for example, setting the maximum temperature in the machine body 1, if the temperature exceeds the set temperature, the temperature in the machine body 1 needs to be rapidly reduced to prevent the damage of the components in the machine body 1, the blowing mechanism 3 comprises a fan, and the shell of the machine body 1 is further provided with corresponding heat dissipation holes for reducing the temperature in the machine body 1, of course, the first temperature sensor 2 can be connected with a buzzer or a display lamp through a PLC controller in the embodiment, as long as the effect of prompting the staff is achieved.

[0032] The machine body 1 is further provided with a heat dissipation device for cooperating with the blowing structure to accelerate the temperature reduction in the machine body 1, the heat dissipation device comprises a water cooling mechanism for reducing the temperature through water circulation and a refrigeration mechanism for refrigeration; the water cooling mechanism comprises a first pipe 4, a second temperature sensor 5 arranged in the first pipe 4 and a circulating assembly for realizing the water circulation in the first pipe 4, the first pipe 4 is located in the direction of the wind blown by the fan, the first pipe 4 is arranged in the machine body 1 and vertically arranged, the first pipe 4 is located in front of the fan, when the temperature in the machine body 1 exceeds the set temperature, the circulating water needs to be circulated into the first pipe 4 through the circulating assembly, since the circulating water is at room temperature, the temperature in the machine body 1 can be rapidly reduced under the action of the fan, since the environment problem of the integrated machine, the water in the circulating assembly is also limited, after the water circulation and the heat exchange between the water in the first pipe 4 and the machine body 1, the temperature of the water in the circulating assembly is gradually increased, the second temperature sensor 5 measures the temperature of the water in the first pipe 4, if the temperature of the water in the circulating assembly cannot rapidly reduce the temperature in the machine body 1, the refrigeration mechanism needs to work.

[0033] Referring to Figures 1-3The refrigerating mechanism comprises a second pipe 6, a third pipe 7, a first electromagnetic valve 8, a third temperature sensor 9, a pushing assembly for pushing water in the second pipe 6 and an adjusting assembly for rapidly reducing the temperature of water in the second pipe 6, the third pipe 7 is arranged as a bent pipe, two ends of the third pipe 7 are connected with the second pipe 6 and the tail end of the first pipe 4 respectively, the first electromagnetic valve 8 is arranged at the connecting position of the second pipe 6 and the third pipe 7, thus the first pipe 4, the second pipe 6 and the third pipe 7 form a U-shaped structure, and the second pipe 6 and the first pipe 4 are arranged in a vertical direction along the blowing direction of the fan, and the first pipe 4 is located closer to the fan, thus the first pipe 4 can also cool the air blown out from the first pipe 4 under the action of the second pipe 6 even if the temperature of the first pipe 4 is higher than that of the second pipe 6, and then the air with a lower temperature can be blown into the machine body 1, greatly accelerating the cooling speed of the machine body 1.

[0034] The circulating assembly comprises a water tank 10 arranged in an external environment, a circulating water pump 11 arranged in the water tank 10, a main pipe 12, a first water pipe 13, a second water pipe 14, three circulating electromagnetic valves 15 and a backwater pipe 16, the water tank 10 is externally connected, and the water in the water tank 10 does not need to be much due to the existence of the adjusting assembly, an output end of the circulating water pump 11 is connected with the main pipe 12, the first water pipe 13 and the second water pipe 14 are respectively connected with two ends of the main pipe 12, the three circulating electromagnetic valves 15 are respectively arranged on the first water pipe 13, the second water pipe 14 and the backwater pipe 16, the backwater pipe 16 is connected with the bottom end of the third pipe 7, and the other end of the backwater pipe 16 is connected with the water tank 10, the water tank 10 is located lower than the bottom end of the first water pipe 13, the side wall of the second pipe 6 is provided with a mounting hole, and the third temperature sensor 9 is arranged in the mounting hole; when it is needed to only open the first pipe 4, the circulating electromagnetic valve 15 on the first pipe 4 is opened and the first electromagnetic valve 8 is closed, so as to prevent circulating water from entering into the second pipe 6, at this time, water circulates in the first pipe 4, realizing the water cooling effect, and when it is needed to open the ice cooling effect in the second pipe 6, the circulating electromagnetic valve 15 on the first pipe 4 is closed and the first electromagnetic valve 8 is closed, water in the water tank 10 is pumped into the second pipe 6 by the circulating water pump 11, refrigeration is carried out by the adjusting assembly, and when the refrigeration is completed, the first electromagnetic valve 8 and the circulating electromagnetic valve 15 on the backwater pipe 16 are still opened, at this time, water in the second pipe 6 flows into the third pipe 7 and then flows into the water tank 10, completing the water circulation work.

[0035] Reference Figures 1-4The adjusting assembly comprises a storage tank 17 detachably arranged on the machine body 1, a cover 18, a receiving pipe 19, an adjusting electromagnetic valve 20 arranged at the bottom of the receiving pipe 19, an opening part for opening the cover 18, a connecting part for connecting the receiving pipe 19 with the second pipe 6, and a monitoring part for monitoring the height of the material in the receiving pipe 19. The storage tank 17 is sealed and contains ammonium nitrate particles. Ammonium nitrate is a commonly used chemical refrigerant. When dissolved in water, it absorbs a large amount of heat, thereby reducing the temperature of the solution. Therefore, the first pipe 4 and the second pipe 6 are both made of a material with good heat conduction performance, so as to facilitate the heat transfer between the sodium nitrate and the air after the temperature of the sodium nitrate is reduced. The opening of the storage tank 17 is sealed by the cover 18. The receiving pipe 19 is fixed in the machine body 1 and connected with the top end of the second pipe 6 through the connecting part. The machine body 1 is provided with an insertion opening 21 at the top. The tank opening of the storage tank 17 is adapted to the insertion opening 21. The insertion opening 21 is arranged at the top. Therefore, the ammonium nitrate can be sealed and carried during daily use. When the cooling needs to be started, the tank opening of the storage tank 17 is inserted into the insertion opening 21. At this time, the installation of the storage tank 17 is completed, and the tank body of the storage tank 17 is located outside the machine body 1.

[0036] The opening part comprises a protrusion 22, an electromagnet 23, and an opening rod 24. The protrusion 22 is fixedly connected to the side wall of the cover 18. The tank opening of the storage tank 17 is provided with a sliding groove 25. The sliding groove 25 is along the length direction of the tank opening of the storage tank 17. Both ends of the sliding groove 25 are open. An arc-shaped groove 26 is arranged on the side wall of the sliding groove 25. The protrusion 22 is slidably adapted to the arc-shaped groove 26. The protrusion 22 is rotated from the sliding groove 25 into the arc-shaped groove 26. A rubber strip 27 is detachably arranged in the position close to the tank opening of the storage tank 17. The opening rod 24 is fixedly arranged at the opening of the receiving pipe 19. The electromagnet 23 is fixedly arranged at the end of the opening pipe. The cover 18 is provided with an opening 28. The opening 28 is adapted to the cross section of the opening rod 24 and is also rectangular. The electromagnet 23 is adsorbed to the cover 18. Since both ends of the sliding groove 25 are through, when the protrusion 22 is rotated into the arc-shaped groove 26, the cover 18 is clamped with the tank opening of the storage tank 17. However, in order to prevent the ammonium nitrate particles from leaking out of the sliding groove 25, the rubber strip 27 is inserted into the position of the sliding groove 25 close to the tank opening of the storage tank 17. After the rubber strip 27 is inserted into the sliding groove 25, it is deformed by being extruded, thereby sealing the sliding groove 25.

[0037] When the tank mouth of the storage tank 17 is inserted into the opening of the insertion port 21, the opening rod 24 is inserted into the opening 28, the electromagnet 23 is powered on, the electromagnet 23 adsorbs the cover 18 to prevent the cover 18 from falling during the movement towards the storage tank 17. Since the cross section of the opening rod 24 and the opening 28 is square, the rotation of the storage tank 17 can be controlled at this time, the relative movement between the storage tank 17 and the cover 18 occurs, the lug 22 rotates from the arc-shaped groove 26 to the sliding groove 25, at this time, the storage tank 17 is continuously inserted into the insertion port 21, the opening rod 24 drives the cover 18 to move towards the storage tank 17, since the ammonium nitrate particles in the storage tank 17 are not full, there is enough space for the opening rod 24 to move, when the cover 18 moves into the tank body of the storage tank 17, at this time, the ammonium nitrate particles fall from the storage tank 17 towards the receiving pipe 19, and the receiving work is completed.

[0038] Referring to Figures 1-4 , the connecting part includes a connecting box 29, a partition 30 movably arranged in the connecting box 29, and a winding group for winding the partition 30. The connecting box 29 is used to connect the receiving pipe 19 and the top end of the second pipe 6. The position where the second water pipe 14 is connected with the second pipe 6 is below the connecting box 29. The partition 30 is used to separate the water in the second pipe 6 from the ammonium nitrate particles in the receiving pipe 19. The area of the partition 30 is greater than the cross-sectional area of the connecting box 29. In this embodiment, the partition 30 is used to separate the water from the ammonium nitrate particles to prevent the water from splashing out and contaminating the ammonium nitrate particles in the receiving pipe 19. Therefore, the partition 30 needs to be made of a material with good water resistance to ensure the isolation of water. The winding group includes two winding ropes 31, two winding rollers 32 and two winding motors 33. The two ends of the partition 30 are fixedly connected with the two winding ropes 31 respectively. The other ends of the two winding ropes 31 are fixedly connected with the peripheral walls of the two winding rollers 32 respectively. The two pairs of vertical inner walls of the connecting box are provided with winding cavities, and the winding cavities are provided with through holes. The winding rollers 32 are rotationally arranged in the winding cavities, and the winding motors 33 are installed in the winding cavities to control the rotation of the winding rollers 32.

[0039] In the initial state, the partition 30 separates the receiving pipe 19 from the second pipe 6, that is, the partition 30 is located in the connecting box 29, and the area of the partition 30 is greater than the area in the connecting box, so that the water is completely isolated. When it is needed to add ammonium nitrate particles into the second pipe 6, the winding motors 33 are controlled to start rotating the winding rollers 32. Under the action of the same frequency and same direction rotation of the two winding motors 33, the winding ropes 31 are pulled out of the winding cavities, that is, there are only winding ropes 31 in the connecting box 29, so the winding ropes 31 will not affect the normal falling of the ammonium nitrate particles. The ammonium nitrate particles fall into the second pipe 6, thereby realizing the refrigeration effect and greatly accelerating the cooling efficiency in the machine body 1.

[0040] Since the second temperature sensor 5 measures the temperature of the water in the first pipe 4, and the third temperature sensor 9 measures the temperature of the water in the second pipe 6, the temperature of the water in the first pipe 4 is initially room temperature water, and after heat exchange with the body 1, the temperature is much higher than that in the second pipe 6, and the temperature in the second pipe 6 is rapidly reduced after the ammonium nitrate particles react with water, and the temperature is much lower than that in the body 1. With the fan blowing the body 1, the air flow in the body 1 is strengthened and the heat exchange is enhanced. At this time, the temperature in the second pipe 6 also gradually approaches the temperature in the body 1, but it is still lower than the temperature in the first pipe 4. Therefore, at this time, the water in the first pipe 4 can be returned to the water tank 10 through the third pipe 7 and the return pipe 16, and the first electromagnetic valve 8 is kept closed to avoid affecting the water in the second pipe 6. When the water in the first pipe 4 is exhausted, the water in the second pipe 6 can be pushed into the first pipe 4 by the push assembly, maximizing the use of ammonium nitrate cooling water.

[0041] Referring to Figures 1-5 , the push assembly includes a push plate 43, a shielding plate 44, a shielding box 45, a shielding motor 46, and a push piece 47 for realizing the reciprocating motion of the push plate. The push plate is slidably connected to the second pipe 6. The push plate 43 is provided with a push port. The shielding plate 44 is rotatably arranged on the push plate. The shielding box 45 is fixed on the push plate 43. The shielding motor 46 is installed in the shielding box 45 and its output end is fixedly connected with one end of the shielding plate 44. The shielding plate 44 is rotated to a position blocking the push port. When the push plate 43 needs to move downward, the push port needs to be in a blocking position. When the push plate 43 moves upward, the push port can be opened. The push piece 47 is an electric push rod in this embodiment. When the water in the second pipe 6 needs to be pushed towards the first pipe 4, the first electromagnetic valve 8 is opened and the circulating electromagnetic valve 15 on the first water pipe 13 is closed, and the shielding motor 46 rotates the shielding plate 44 until the push port is blocked. At this time, the push piece 47 moves the push plate downward until it moves to the position of the first electromagnetic valve 8, i.e. the water in the second pipe 6 has been pushed into the third pipe 7 and the second pipe 6. The water in the second pipe 6 can still continue to cool. At this time, the first electromagnetic valve 8 needs to be closed, the push port needs to be opened, the push plate 43 needs to be pulled upward to the initial position, the circulating electromagnetic valve 15 on the second water pipe 14 needs to be opened, the water in the water tank 10 needs to be pumped into the second pipe 6, the adjusting electromagnetic valve 20 at the bottom of the auxiliary pipe needs to be opened, and the winding rope 31 needs to be controlled to be located in the connecting box 29. The ammonium nitrate particles fall into the second pipe 6. At this time, the temperature of the water in the second pipe 6 is rapidly reduced, so the old ice water in the first pipe 4 and the new ice water in the second pipe 6 continue to cool the body 1, improving the utilization efficiency and accelerating the cooling of the body 1.

[0042] The monitoring part comprises an infrared emitter 34, an infrared receiver 35, a control group for synchronizing the infrared emitter 34 with the material height in the receiving pipe 19, the infrared emitter 34 is fixed in the machine body 1 and faces the lowest end of the receiving pipe 19, the infrared receiver 35 is slidingly arranged on the outer wall of the receiving pipe 19, when the infrared receiver 35 moves to receive the signal of the infrared emitter 34, it proves that the ammonium nitrate in the receiving pipe 19 has been consumed, similarly, the infrared receiver 35 can also be controlled by the PLC controller to be connected with a buzzer or a display lamp for warning the staff; the control group comprises a control disc 36, two magnet blocks 37 and a partition plate 38, the weight of the control disc 36 is greater than that of the infrared receiver 35, the two magnet blocks 37 are fixedly connected with the control disc 36 and the infrared receiver 35 respectively, the receiving pipe 19 is provided with a suction port on the side wall, the partition plate 38 is fixed in the suction port, the two magnet blocks 37 are located on the two sides of the partition plate 38 and are attracted to each other, the area of the control disc 36 is smaller than the inner diameter of the receiving pipe 19, in the embodiment, the control disc 36 is located above the ammonium nitrate particles and is always in a horizontal state, the weight of the control disc 36 is greater than that of the infrared receiver 35, mainly to ensure that the control disc 36 can drive the external infrared receiver 35 to move together, so as to ensure that the position of the infrared receiver 35 is the position of the ammonium nitrate particles, and the partition plate 38 mainly reduces the thickness and adopts a material with the smallest influence on the attraction between the two magnet blocks 37 in the embodiment, so that the two magnet blocks 37 are in the adhered state together during the whole process.

[0043] The receiving pipe 19 is also provided with a traction group for pulling the control disc 36, the traction group comprises a traction box 39, a traction rope 40, a traction roller 41 and a traction motor 42, the traction box 39 is fixed at the top end of the side wall of the receiving pipe 19, the traction box 39 is provided with a traction hole at the bottom end, the traction rope 40 is fixedly connected with the control disc 36 through the traction hole, the other end of the traction rope 40 is fixedly connected with the traction roller 41, and the traction motor 42 is installed in the traction box 39 and is used for controlling the rotation of the traction roller 41; when the ammonium nitrate particles in the receiving pipe 19 are consumed, the control disc 36 needs to be pulled to the initial position, the traction motor 42 is controlled to drive the traction roller 41 to rotate, the traction roller 41 pulls and winds the traction rope 40 upwards, and the control disc 36 is pulled to the top of the traction box 39, so as to facilitate the subsequent feeding in the receiving pipe 19, and during the monitoring of the position of the ammonium nitrate particles in the receiving pipe 19 by the control disc 36, the traction rope 40 is always in a relaxed state, so as not to affect the position of the control disc 36.

[0044] The implementation principle of the multifunctional audio and video integrated conference machine is as follows: when only the first pipe 4 needs to be opened, the circulating electromagnetic valve 15 on the first pipe 4 is opened and the first electromagnetic valve 8 is closed, so that the circulating water does not enter the second pipe 6, at this time, the water circulates in the first pipe 4, realizing the water cooling effect, and when the ice cooling effect in the second pipe 6 needs to be opened, the circulating electromagnetic valve 15 on the first pipe 4 and the first electromagnetic valve 8 are closed, the water in the water tank 10 is pumped into the second pipe 6 by the circulating water pump 11, and the refrigeration is adjusted by the adjusting assembly, when the refrigeration is completed, the first electromagnetic valve 8 and the circulating electromagnetic valve 15 on the backwater pipe 16 are still opened, at this time, the water flows into the third pipe 7 from the second pipe 6 and then flows into the water tank 10, completing the water circulation work.

[0045] When the tank opening of the storage tank 17 is inserted into the opening of the insertion opening 21, the opening rod 24 is inserted into the opening 28, the electromagnet 23 is powered on, the electromagnet 23 adsorbs the cover 18, so that the cover 18 does not fall during the movement towards the storage tank 17, since the cross section of the opening rod 24 and the opening 28 is square, at this time, the rotation of the storage tank 17 can be controlled, the relative movement between the storage tank 17 and the cover 18 occurs, the convex block 22 rotates from the arc-shaped groove 26 to the sliding groove 25, at this time, the storage tank 17 is continuously inserted into the insertion opening 21, the cover 18 moves towards the storage tank 17 together with the opening rod 24, since the ammonium nitrate particles in the storage tank 17 are not full, there is enough space for the movement of the opening rod 24, when the cover 18 moves into the tank body of the storage tank 17, at this time, the ammonium nitrate particles fall from the storage tank 17 towards the receiving pipe 19, completing the receiving work; since the second temperature sensor 5 measures the temperature of the water in the first pipe 4 and the third temperature sensor 9 measures the temperature of the water in the second pipe 6, the water temperature in the first pipe 4 is room temperature water at the beginning, since the heat exchange with the machine body 1, the temperature is much higher than that in the second pipe 6, and the temperature in the second pipe 6 is rapidly lowered after the reaction of the ammonium nitrate particles and water, which is much lower than the temperature in the machine body 1, with the blowing of the fan on the machine body 1, the air flow and heat exchange in the machine body 1 are enhanced, at this time, the temperature in the second pipe 6 also gradually approaches the temperature in the machine body 1, but it is still lower than the temperature in the first pipe 4, so at this time, the water in the first pipe 4 can be returned to the water tank 10 through the third pipe 7 and the backwater pipe 16, and the first electromagnetic valve 8 is kept closed to avoid affecting the water in the second pipe 6, when the water in the first pipe 4 is finished, the water in the second pipe 6 can be pushed into the first pipe 4 by the pushing assembly, maximizing the use of the ammonium nitrate refrigeration water.
