Description

Technical Field

[0001] This utility model relates to the technical field of glass bicolor level gauges, specifically a multifunctional glass bicolor level gauge. Background Technology

[0002] The level of a liquid medium in a container is called the liquid level, and the instrument used to measure the liquid level is called a level gauge. A level gauge is a type of level instrument. Types of level gauges include tuning fork vibrating type, magnetic levitation type, pressure type, ultrasonic type, sonar wave type, magnetic float type, and radar type. Bicolor level gauges are a product of social development and are widely used in petroleum, chemical, and other fields, particularly in medium and low-pressure boilers and storage containers.

[0003] Reference patent (Publication No.: CN212058964U; Publication Date: 2020-12-01) discloses a corrosion-resistant dual-color level gauge, including a dual-color level gauge body. A first fixing block is fixedly connected to one end of the dual-color level gauge body. A first movable ring is rotatably connected to the outer wall of the first fixing block away from the dual-color level gauge body. A first connecting pipe is fixedly connected inside the first movable ring. A groove is formed inside the first fixing block, and the first connecting pipe passes through the groove. By setting a spring inside the sliding groove, the addition of the spring allows the locking rod to return to its original position. The addition of the first movable ring increases the stability of the first connecting pipe and the first fixing block. The addition of the sliding plate allows the spring's squeezing force to drive the locking rod to move, enabling the user to more intuitively observe the dual-color level gauge body. The addition of multiple locking grooves allows for fine adjustment of the orientation of the dual-color level gauge body.

[0004] Based on the fact that traditional level gauges mentioned in the above patents often face challenges from various external factors during long-term use, the level gauges usually do not have a protective outer shell, making them prone to direct collisions with the outer wall of the level gauge, which may lead to damage to the level gauge or measurement errors, thereby affecting the normal operation of the production process and the safe operation of the equipment. In addition, in complex or harsh working environments, single-layer glass level gauges are easily affected by external collisions, thus affecting their performance. Therefore, this utility model provides a multifunctional glass dual-color level gauge. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional glass dual-color level gauge, which solves the problem that traditional level gauges often face challenges from various external factors during long-term use. Typically, level gauges do not have a protective outer shell, making them susceptible to direct impacts with the outer wall of the level gauge, which may lead to damage or measurement errors, thereby affecting the normal operation of the production process and the safe operation of the equipment. In addition, in complex or harsh working environments, single-layer glass level gauges are easily affected by external impacts, thus affecting their performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional glass bicolor level gauge, comprising a bicolor level gauge body, wherein a protective mechanism for the level gauge is provided on the bicolor level gauge body, the protective mechanism comprising:

[0007] The shielding assembly includes a lower valve seat fixed to the lower end of the body of the dual-color level gauge, a support frame connected to the front end face of the lower valve seat via a push assembly, a pair of fixing plates fixed to the upper end face of the lower valve seat, a support shaft rotatably connected inside the fixing plates, and a second protective shell fixed to the outer wall of the support shaft.

[0008] The explosion-proof component includes a rubber pad fixed to the inner wall of the dual-color level gauge body, and an inner layer of glass is fixed to the inner wall of the rubber pad.

[0009] Preferably, the push assembly includes a fixing block fixed to the front end face of the lower valve seat, an electric push rod fixed to the upper end face of the fixing block, a support frame located at the telescopic end of the electric push rod, and the support frame being fixedly connected to the telescopic end of the electric push rod.

[0010] Preferably, the support frame has a U-shaped structure, toothed blocks are fixed on both side walls of the support frame, and a transmission gear is fixed on the outer wall of the support shaft, with the transmission gear meshing with the toothed blocks.

[0011] Preferably, a positioning bolt is fixed to the inner wall of the second protective housing, and a third protective housing is provided on the side of the upper end face of the lower valve seat that is symmetrical about the second protective housing. The side wall of the third protective housing is provided with a positioning groove that is connected to the positioning bolt.

[0012] Preferably, an upper valve seat is fixed to the upper end of the dual-color level gauge body, and a first protective shell is fixed to the front end face of the lower valve seat.

[0013] Preferably, the rubber pad has a U-shaped structure, and the two ends of the inner glass layer are embedded in the inner wall of the rubber pad.

[0014] Beneficial effects

[0015] This invention provides a multifunctional glass dual-color level gauge. Compared with the prior art, it has the following advantages:

[0016] Firstly, the support frame of this utility model is raised and lowered by an electric push rod. Then, the toothed blocks on both sides of the support frame drive the support shaft to rotate on the fixed plate, which in turn drives the second and third protective shells to open and close, thereby protecting the surface of the level gauge and effectively preventing damage or measurement errors caused by accidental collisions due to external factors during the operation of the level gauge, thus improving the overall safety of the level gauge.

[0017] Secondly, the outer wall of the dual-color level gauge in this utility model is made of glass. The inner glass layer is embedded at both ends in the inner wall of the rubber pad and connected to the level gauge. This increases the tightness of the connection between the glass and the level gauge body. Furthermore, the elastic buffering effect of the rubber further reduces the impact of external factors on the glass, preventing the glass from breaking or being damaged. This ensures that the level gauge has a double-layer glass structure, which has higher strength and stability than single-layer glass. It can better resist external pressure, impact and vibration, thereby extending the service life of the level gauge and preventing direct leakage of the medium when the glass breaks, thus playing a certain safety protection role.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a multifunctional glass bicolor level gauge, including a bicolor level gauge body 1, on which a protective mechanism for the level gauge is provided, the protective mechanism including:

[0025] The shielding assembly includes a lower valve seat 201 fixed at the lower end of the dual-color level gauge body 1, a support frame 302 connected by a push assembly on the front end face of the lower valve seat 201, a pair of fixing plates 4 fixed at the upper end face of the lower valve seat 201, a support shaft 401 rotatably connected inside the fixing plate 4, and a second protective shell 5 fixed on the outer wall of the support shaft 401.

[0026] The explosion-proof component includes a rubber pad 6 fixed to the inner wall of the dual-color level gauge body 1, and an inner glass layer 601 fixed to the inner wall of the rubber pad 6.

[0027] In a preferred embodiment, the push assembly includes a fixing block 3 fixed to the front end face of the lower valve seat 201, an electric push rod 301 fixed to the upper end face of the fixing block 3, a support frame 302 located at the telescopic end of the electric push rod 301, the support frame 302 being fixedly connected to the telescopic end of the electric push rod 301, the support frame 302 having a U-shaped structure, toothed blocks 303 fixed to both side walls of the support frame 302, and a transmission gear 402 fixed to the outer wall of the support shaft 401, the transmission gear 402 being meshed with the toothed blocks 303. The support frame 302 is raised and lowered by the electric push rod 301, and then the toothed blocks 303 on both sides of the support frame 302 are driven to ensure that the support shaft 401 rotates on the fixing plate 4, thereby driving the second protective shell 5 and the third protective shell 501 to open and close, thus protecting the surface of the level gauge and effectively preventing damage or measurement errors caused by accidental collisions due to external factors during the operation of the level gauge, thereby improving the overall safety of the level gauge.

[0028] In a preferred embodiment, a positioning bolt 503 is fixed to the inner wall of the second protective housing 5, and a third protective housing 501 is provided on the side of the upper end face of the lower valve seat 201 that is symmetrical about the second protective housing 5. The side wall of the third protective housing 501 is provided with a positioning groove 502 that corresponds to and is connected to the positioning bolt 503. When the second protective housing 5 is opened and closed, the positioning groove 502 on the second protective housing 5 and the third protective housing 501 are closed to ensure the stability of the protective housing when it is closed.

[0029] In a preferred embodiment, the upper end of the dual-color level gauge body 1 is fixed with an upper valve seat 2, which is usually connected to the detection equipment, including containers and storage tanks, by means of flange or threaded connection. The front end face of the lower valve seat 201 is fixed with a first protective shell 202, which is used to protect the exposed tooth block 303 and transmission gear 402.

[0030] In a preferred embodiment, the rubber pad 6 has a U-shaped structure, with the inner glass layer 601 embedded at both ends in the inner wall of the rubber pad 6.

Furthermore, the elastic buffering effect of the rubber further reduces the impact of external factors on the glass, preventing the glass from breaking or being damaged. This ensures that the level gauge has a double-layer glass structure, which has higher strength and stability than a single-layer glass structure. It can better resist external pressure, impact, and vibration, thereby extending the service life of the level gauge and preventing direct leakage of the medium when the glass breaks, thus providing a certain degree of safety protection.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the support frame 302 is raised and lowered by the electric push rod 301. Then, the toothed blocks 303 on both sides of the support frame 302 drive the support shaft 401 to rotate on the fixed plate 4, thereby opening and closing the second protective shell 5 and the third protective shell 501. This protects the surface of the level gauge and effectively prevents damage or measurement errors caused by accidental collisions due to external factors during the operation of the level gauge. When the second protective shell 5 is opened and closed, the positioning groove 502 on the second protective shell 5 and the third protective shell 501 are closed to ensure the stability of the protective shell when it is closed.

[0033] The outer wall of the dual-color level gauge body 1 is made of glass. The inner glass 601 is embedded at both ends in the inner wall of the rubber pad 6 and connected to the level gauge. This increases the tightness of the connection between the glass and the level gauge body. The elastic buffering effect of the rubber further reduces the impact of external factors on the glass and prevents the glass from breaking or being damaged.
