Description

Technical Field

[0001] This utility model relates to the field of petrochemical safety protection technology, specifically to a petrochemical gas detection instrument. Background Technology

[0002] The field of petrochemical safety protection involves ensuring the safety and protective measures during petrochemical production processes. Flammable and explosive gases are generated during petrochemical production. When the concentration of these gases reaches the safety threshold, safety accidents can occur. Therefore, it is necessary to detect flammable and explosive gases using petrochemical detection instruments.

[0003] A search revealed that CN221446036U discloses a petrochemical gas detection instrument, relating to the field of petrochemical safety protection. The instrument includes a detection body, with a connecting terminal on one side of its outer surface and an alarm terminal on the other side. A detection terminal is located at the bottom of the outer surface. A display area is located at the front of the detection body, and a dust-wiping structure is also located at the front. This dust-wiping structure includes a sweeping rod. A fixing block is fixedly installed at the bottom of the connecting terminal on the outer surface of the detection body. The sweeping rod is rotatably mounted at the front of the fixing block. A pattern wheel is fixedly installed at the rear of one end of the sweeping rod. Two large gears are rotatably mounted at the front of the fixing block.

[0004] The aforementioned utility model, by incorporating a dust-wiping structure, prevents the display area from being obstructed by environmental contaminants such as oil and fumes during long-term use, thus ensuring the visibility of flammable gas concentration. However, in actual use, the display area is constantly wiped clean by dry scraping with the bristles at the rear of the sweeping bar. Dry scraping causes the bristles to wear down rapidly due to hard friction, resulting in a rough surface and reduced lifespan. Furthermore, the lack of lubrication between the bristles and the display area surface increases wear and may even lead to scratches, affecting the visibility of flammable gas concentration.

[0005] Therefore, it is of great importance to design a petrochemical gas detection instrument to address the above-mentioned shortcomings. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model designs a petrochemical gas detection instrument. This petrochemical gas detection instrument aims to solve the technical problem that existing petrochemical gas detection instruments use dry scraping to wipe the surface of the display, which increases wear on the display area and may even cause scratches on the display area, affecting the ability to view the concentration of flammable gases.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A petrochemical gas detection instrument includes a detection body, a mounting frame fixedly installed on the top of the detection body, a drive mechanism mounted on the mounting frame, a connecting plate fixedly installed at the bottom of the drive mechanism, a scraper fixedly installed at the bottom of the connecting plate, a water tank fixedly installed at the bottom of the detection body, baffles fixedly installed around the top of the water tank, a miniature water pump fixedly installed on the right side of the water tank, the input end of the miniature water pump being connected to the interior of the water tank, and a spray head fixedly installed at the top front of the detection body, the right end of the spray head being fixedly connected to the output end of the miniature water pump via a connecting pipe.

[0009] As a preferred embodiment of this utility model, the driving mechanism includes a small motor fixedly installed on the top of the back of the mounting bracket.

A connecting plate is fixedly installed at the front end of the rotating shaft.

[0010] As a preferred embodiment of this utility model, the bottom end of the mounting bracket is fixedly connected to the detection body by mounting screws, and a movable through groove is provided inside the mounting bracket at a position corresponding to the transmission arm.

[0011] As a preferred embodiment of this utility model, a rubber scraper is fixedly installed on the back of the scraper, and both the upper and lower ends of the rubber scraper are fixedly connected to the scraper by a first fixing screw.

[0012] As a preferred embodiment of this utility model, a support plate is fixedly installed at the bottom of the detection body and on the outside of the water tank, and the front of the support plate is fixedly connected to the support plate by a second fixing screw.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example:

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A petrochemical gas detection instrument includes a detection body 1, a mounting frame 2 fixedly installed on the top of the detection body 1, a drive mechanism 3 installed on the mounting frame 2, a connecting plate 4 fixedly installed at the bottom of the drive mechanism 3, a scraper 5 fixedly installed at the bottom of the connecting plate 4, a water tank 6 fixedly installed at the bottom of the detection body 1, baffles 7 fixedly installed around the top of the water tank 6, a micro water pump 8 fixedly installed on the right side of the water tank 6, the input end of the micro water pump 8 being connected to the interior of the water tank 6, and a spray head 9 fixedly installed at the top front of the detection body 1, the right end of the spray head 9 being fixedly connected to the output end of the micro water pump 8 via a connecting pipe 10.

[0024] First, the drive mechanism 3 includes a small motor 301 fixedly installed on the top of the back of the mounting frame 2. A reducer 302 is fixedly installed on the drive end of the small motor 301. A rotating block 303 is fixedly installed on the output end of the reducer 302. A transmission arm 304 is rotatably connected to the front of the rotating block 303. A connecting arm 305 is rotatably connected to the bottom end of the transmission arm 304. A rotating shaft 306 is fixedly installed at the bottom end of the connecting arm 305, and the rotating shaft 306 is rotatably connected to the mounting frame 2. A connecting plate 4 is fixedly installed at the front end of the rotating shaft 306. When the small motor 301 is started, its speed is reduced by the reducer 302, and then the rotating block 303 is driven to rotate. Since the bottom end of the connecting arm 305 rotates with the mounting frame 2 through the rotating shaft 306, when the rotating block 303 rotates, the connecting arm 305 is driven to swing back and forth under the transmission of the transmission arm 304, thereby driving the scraper 5 at the front end of the connecting plate 4 to clean the surface of the display area of ​​the detection body 1.

[0025] Furthermore, the bottom end of the mounting bracket 2 is fixedly connected to the detection body 1 by mounting screws 307. A movable through groove 308 is provided inside the mounting bracket 2 at the position corresponding to the transmission arm 304. The mounting bracket 2 is installed and fixed on the detection body 1 by mounting screws 307, thereby facilitating the disassembly and maintenance of the components on the mounting bracket 2. The transmission arm 304 moves inside the movable through groove 308.

[0026] Then, a rubber scraper 501 is fixedly installed on the back of the scraper 5. Both the upper and lower ends of the rubber scraper 501 are fixedly connected to the scraper 5 by the first fixing screw 502. When the scraper 5 is used to clean the surface of the display area of ​​the detection body 1, the rubber scraper 501 is used for cleaning. During this process, water is sprayed out by the water spray head 9 for lubrication and cleaning assistance. This not only improves the cleaning effect of the display area, but also extends the life of the rubber scraper 501 and protects the surface of the display area. Moreover, the rubber scraper 501 can be disassembled and replaced after it is damaged or aged.

[0027] Furthermore, a support plate 601 is fixedly installed at the bottom of the testing body 1 and on the outside of the water tank 6. The front of the support plate 601 is fixedly connected to the support plate 601 by a second fixing screw 602. The water tank 6 is installed at the bottom of the testing body 1 through the support plate 601, which facilitates the disassembly and maintenance of the water tank 6.

[0028] Secondly, a filter screen 603 is fixedly installed at the top inside the water tank 6, and the filter screen 603 is installed at an angle inside the water tank 6. When cleaning the surface of the display area of ​​the detection subject 1, the water inside the water tank 6 is drawn out by the micro water pump 8, and then introduced into the spray head 9 through the connecting pipe 10 and sprayed out. The sprayed water is used for lubrication and cleaning assistance. The cleaned water is restricted and guided by the baffle 7 and returned to the inside of the water tank 6. It is then reused after being filtered by the filter screen 603, thereby ensuring the cleaning effect while saving water.

[0029] Finally, a drain outlet is provided on the left side of the front of the water tank 6, and a cover 604 is threaded onto the outside of the drain outlet. A liquid level window 605 is installed on the right side of the front of the water tank 6. The water level window 605 is used to periodically observe the water volume and water quality in the water tank 6, so as to facilitate timely replenishment and replacement of water. When the internal water flow is insufficient to meet the quality of the cleaning water, the drain outlet is opened to replace the water.

[0030] In this embodiment, the specific implementation scenario is as follows: The small motor 301 is started and its speed is reduced by the reducer 302, which then drives the rotating block 303 to rotate. Since the bottom end of the connecting arm 305 rotates with the mounting bracket 2 through the rotating shaft 306, when the rotating block 303 rotates, it drives the connecting arm 305 to swing back and forth under the transmission of the transmission arm 304, thereby driving the scraper 5 at the front end of the connecting plate 4 to clean the surface of the display area of ​​the detection body 1. The cleaning is carried out by the rubber scraper 501 on the back of the scraper 5. During this process, the water inside the water tank 6 is pumped out by the micro water pump 8. The water is then introduced into the spray head 9 through the connecting pipe 10 and sprayed out. The sprayed water is used for lubrication and cleaning. The cleaned water is restricted and guided by the baffle 7 and then returned to the water tank 6. It is then filtered by the filter screen 603 and reused. The whole operation process is simple and convenient. Compared with existing petrochemical gas detection instruments, this utility model can not only improve the cleaning effect of the display area, but also extend the life of the rubber scraper 501, protect the surface of the display area, and save water while ensuring the cleaning effect.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
