Description

Technical Field

[0001] This utility model relates to the technical field of instrument heat dissipation auxiliary devices, and in particular to a heat protection device for industrial automatic regulating instruments. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to instrument heat dissipation auxiliary devices is also constantly improving. Industrial automatic control instrument heat protection devices are auxiliary devices used in the use of industrial automatic control instruments to dissipate heat inside the instruments, so as to enable them to perform better subsequent safe operation. They have been widely used in the field of instrument heat dissipation.

[0003] The patent document with publication number "CN210535365U" discloses a heat protection device for an industrial automatic regulating instrument; it includes a base plate and an instrument body. The front side of the instrument body is equipped with a display screen, control keys and a speaker. An air inlet pipe is sealed and connected to the upper left side of the instrument body, and an exhaust port is connected to the right side of the instrument body. A blower is connected to the air inlet pipe.

[0004] Although the aforementioned patent documents have solved the problems of poor heat dissipation due to weak heat exchange through gas flow within the instrument body, the following drawbacks still exist: when the brush scrapes off the blockages on the filter screen by directly pushing the push plate, the lighter blockages tend to adhere directly to the inner wall of the U-shaped tube. As the blockages increase, the wall of the U-shaped tube becomes thicker, which is not conducive to subsequent air flow and also hinders the use of heat protection devices in industrial automatic regulating instruments. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the prior art: when the brush scrapes off the blockages on the filter screen by directly pushing the push plate, the lighter blockages tend to adhere directly to the inner wall of the U-shaped tube. As the amount of blockages increases, the wall of the U-shaped tube becomes thicker, which is not conducive to the subsequent airflow and also to the use of the heat protection device for industrial automatic regulating instruments. Therefore, this invention proposes a heat protection device for industrial automatic regulating instruments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An industrial automatic regulating instrument heat protection device includes an instrument body, a cooling box and a U-shaped tube. A fixed tube is fixedly connected to the U-shaped tube, and a filter screen is fixedly connected inside the fixed tube. Openings are provided on both sides of the inner wall of the fixed tube. A sealing shell and a sealing plate are slidably installed in the two openings respectively. The sealing shell is connected to the sealing plate through a fixed rod. An inclined scraper is fixedly connected inside the sealing shell.

[0008] A bracket is fixedly connected to the fixed tube. A sliding groove is provided on the bracket. A moving component is provided on the bracket. The moving component includes a sliding rod that is slidably installed on the bracket. The sliding rod is connected to the sealing plate through a pull rope. A first spring is fixedly provided on one side of the sealing plate.

[0009] Preferably, a plurality of guide plates are fixedly connected to the bracket, and each guide plate has a through hole for the pull rope to pass through, and one of the guide plates is fixedly connected to the first spring.

[0010] Preferably, the sealed shell has a receiving cavity inside, the scraper is fixedly connected to the inner wall of the receiving cavity, and the upper inner wall of the receiving cavity has a feed inlet.

[0011] Preferably, a cover plate is connected to one side of the sealing shell by two screws, and a rubber ring is fixedly connected to the cover plate.

[0012] Preferably, a Y-shaped rod is slidably connected to the bracket, and both the sliding rod and the sealing shell are provided with slots for connecting the Y-shaped rod.

[0013] Preferably, a second spring is sleeved on the Y-shaped rod, one end of the second spring is fixedly connected to the Y-shaped rod, and the other end of the second spring is fixedly connected to the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Pulling the sliding rod causes it to slide relative to the bracket. Under the transmission action of the inelastic rope, the sealing plate moves simultaneously. Under the transmission action of the fixed rod, the sealing shell moves simultaneously. As the scraper moves close to the lower surface of the filter screen, it can scrape away the blockages accumulated on the surface of the filter screen. Under the action of gravity, the blockages will fall through the feed port into the collection chamber for collection. This effectively prevents the blockages from falling directly onto the inner wall of the U-shaped tube, thus preventing the tube wall from thickening. This is beneficial for subsequent air circulation and also for the use of heat protection devices in industrial automatic regulating instruments. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 An industrial automatic regulating instrument heat protection device includes an instrument body 1, a cooling box, and a U-shaped tube 2. A fixing tube 3 is fixedly connected to the U-shaped tube 2, and the fixing tube 3 communicates with the U-shaped tube 2. A filter screen 16 is fixedly connected inside the fixing tube 3. Openings are provided on both sides of the inner wall of the fixing tube 3. A sealing shell 9 and a sealing plate 11 are slidably installed in the two openings, respectively. The sealing shell 9 is connected to the sealing plate 11 through a fixing rod 10. An inclined scraper 15 is fixedly connected inside the sealing shell 9. A bracket 4 is fixedly connected to the fixing tube 3. A sliding groove 17 is provided on the bracket 4. A moving component is provided on the bracket 4. The moving component includes a sliding rod 5 slidably installed on the bracket 4. The sliding rod 5 is connected to the sealing plate 11 through a pull rope 14. A first spring 12 is fixedly provided on one side of the sealing plate 11.

[0024] Multiple guide plates 13 are fixedly connected to the bracket 4. Each guide plate 13 has a through hole for the pull rope 14 to pass through. One guide plate 13 is fixedly connected to the first spring 12. A storage cavity is opened inside the sealing shell 9. The scraper 15 is fixedly connected to the inner wall of the storage cavity. A feed port is opened on the upper inner wall of the storage cavity. The multiple guide plates 13 guide the pull rope 14 and limit the movement trajectory of the pull rope 14. When the scraper 15 moves close to the lower surface of the filter screen 16, it can scrape off the blockages accumulated on the surface of the filter screen 16. Under the action of gravity, the blockages will fall through the feed port into the storage cavity for collection. The sealing plate 11 and the sealing shell 9 have good sealing performance when connected to the fixed tube 3, which can effectively prevent air from seeping out from the connection gap.

[0025] A cover plate 8 is connected to one side of the sealing shell 9 by two screws. A rubber ring is fixedly connected to the cover plate 8. The rubber ring on one side of the cover plate 8 is in close contact with the surface of the sealing shell 9, which can effectively improve the sealing performance when the cover plate 8 and the sealing shell 9 are connected. By passing one end of each screw through the cover plate 8 and threading it to the sealing shell 9, the cover plate 8 and the sealing shell 9 can be firmly connected together, and the sealing performance after connection is good, which can effectively prevent air leakage.

[0026] A Y-shaped rod 6 is slidably connected to the bracket 4. The slide rod 5 and the sealing shell 9 are all provided with slots for connecting the Y-shaped rod 6. A second spring 7 is sleeved on the Y-shaped rod 6. One end of the second spring 7 is fixedly connected to the Y-shaped rod 6, and the other end of the second spring 7 is fixedly connected to the bracket 4. When the two ends of the Y-shaped rod 6 are engaged with the slots on the sealing shell 9 and the slide rod 5 respectively under the elastic force of the second spring 7, it can effectively prevent the slide rod 5 from sliding relative to the bracket 4, and also prevent the sealing shell 9 from sliding relative to the fixed tube 3.

[0027] In this invention, during use, pulling the sliding rod 5 causes it to slide relative to the bracket 4. Since the two ends of the inelastic pull rope 14 are fixedly connected to the sealing plate 11 and the sliding rod 5 respectively, the sealing plate 11 moves simultaneously under the transmission action of the inelastic pull rope 14. The sealing plate 11 has a T-shaped cross-section and is slidably connected to the sliding groove 17, allowing it to slide along the groove 17. Since the two ends of the fixing rod 10 are fixedly connected to the sealing plate 11 and the sealing shell 9 respectively, the sealing shell... 9. Simultaneously, the first spring 12 deforms. In the initial state, the upper end of the scraper 15 is in close contact with the edge of the lower surface of the filter screen 16. As the scraper 15 moves close to the lower surface of the filter screen 16, it can scrape off the blockages accumulated on the surface of the filter screen 16. Under the action of gravity, the blockages will fall through the feed port into the collection chamber for collection. This can effectively prevent the blockages from falling directly onto the inner wall of the U-shaped tube 2, thereby preventing the tube wall of the U-shaped tube 2 from thickening. This is beneficial for the subsequent air circulation and also for the use of the heat protection device of the industrial automatic regulating instrument.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
