Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of liquid level gauge equipment, in particular to a liquid level gauge with a protective structure. Background Art
[0002] Liquid level gauges are widely used in a variety of industries, including but not limited to chemical, petroleum, food processing, water treatment, power generation, papermaking, metallurgy, shipbuilding, and boilers. In these fields, liquid level gauges are used to ensure the stability and safety of production processes. By monitoring liquid level changes in real time, they can promptly adjust the liquid supply or issue alarms to prevent accidents caused by excessively high or low liquid levels.
[0003] At present, the existing liquid level gauges with protective structures on the market have the following shortcomings during use: only a protective shell is provided to protect the liquid level gauge, and the protective shell is directly connected to the liquid level gauge body. When the protective shell is hit, the impact force generated will be directly transmitted to the internal components of the liquid level gauge, causing them to loosen, dislocate or even be damaged, and the liquid level gauge is not effectively protected. In order to monitor the position of the liquid in real time, the existing liquid level gauges with protective structures will add a piece of glass to the protective shell for personnel to observe. However, in actual use, the glass is easy to break when it is hit, and a large amount of fragments will be generated after the glass is broken. These fragments may splash into the surrounding environment, causing harm to personnel, posing a major safety hazard. At the same time, damage to the glass of the liquid level gauge will also cause the liquid level gauge to be unable to be used normally, and then the real-time monitoring of the liquid level changes cannot be timely understood, which can easily cause serious economic losses to the enterprise. In view of this, we propose a liquid level gauge with a protective structure. Utility Model Content
[0004] The purpose of the present utility model is to provide a liquid level gauge with a protective structure to solve the problems raised in the above background technology.
[0005] In view of this, the present invention provides a liquid level gauge with a protective structure, comprising a liquid level gauge body, and further comprising:
[0006] Protective shell 1, wherein protective shell 2 is disposed within said protective shell 1, and the level gauge body is fixedly mounted within said protective shell 2, with both ends of said level gauge body respectively penetrating the top and bottom of said protective shell 2 and both penetrating the rear side of said protective shell 1 and extending to the outside;
[0007] Two limit frames (1), each of which is fixedly mounted on one side of the inner wall of the protective shell (1), and each of which is slidably mounted with a slider (1), one side of which is fixedly mounted with a damper (1) fixed to one side of the protective shell (2), and a spring (1) sleeved on the damper (1);
[0008] Two second limit frames, both of which are fixedly mounted on the other side of the inner wall of the first protective shell, and each of which is slidably mounted with a second slider, one side of which is fixedly mounted with a second damper fixed to the other side of the second protective shell, and a second spring sleeved on the second damper;
[0009] Two limit frames (3), both of which are fixedly mounted on the rear side of the inner wall of the protective shell (1), and each of which has a slider (3) slidably mounted therein, a damper (3) fixed to the rear side of the protective shell (2) being fixedly mounted on one side of the slider (3), and a spring (3) being sleeved on the damper (3);
[0010] Two slide grooves are symmetrically opened in the protective shell one and located on the front side of the protective shell two, and a baffle is slidably installed between the two slide grooves.
[0011] In the above technical solution, further comprising:
[0012] Two fixing rings, the two fixing rings are fixedly mounted on both ends of the liquid level gauge body, the two fixing rings are respectively located above and below the second protective shell, and the two fixing rings are both located in the inner cavity of the first protective shell;
[0013] Two round covers, each of which is slidably mounted on both ends of the liquid level gauge body and is located at the rear side of the protective shell 1. A circular ring is fixedly mounted at the rear side of the protective shell 1 and located inside the round cover. The round cover and the fixed ring are fixed by a plurality of elastic ropes;
[0014] A glass sheet is fixedly mounted on the front side of the second protective shell.
[0015] In this technical solution, during use, when the liquid level gauge body is hit from the front, the protective shell 1 will drive the circular ring to move toward the rear side of the protective shell 1, and the circular ring will then squeeze the circular cover, causing the circular cover to slide on the liquid level gauge body. At the same time, the circular cover will stretch the elastic cord, causing the elastic cord to extend and generate a large elastic force. Subsequently, the elastic cord and the spring 3 will contract. At the same time, under the tension of the elastic cord and the spring 3, one end of the elastic cord will pull the circular cover to move and squeeze the circular ring, causing the circular ring to squeeze the protective shell 1 and restore its original position. At the same time, under the tension of the elastic cord itself, the circular cover will be pulled to always be in close contact with the circular ring, ensuring that no dust will enter the protective shell 1 from between the circular cover and the circular ring.
[0016] When one side or the other side of the level gauge body is hit, the protective shell will drive the ring to slide inside the round cover.
[0017] In the above technical solution, further, both ends of the elastic rope are tightly adhered to the fixing ring and the round cover respectively.
[0018] In this technical solution, the stability of the fixing ring and the round cover structure is ensured.
[0019] In the above technical solution, further, the circular ring is slidably connected to the circular cover, and the cross section of the circular ring is an L-shaped structure.
[0020] In this technical solution, when one side or the other side of the liquid level meter body is impacted, the protective shell will drive the ring to slide normally in the round cover, ensuring that when the ring slides normally in the normal round cover, dust will not easily enter the inner cavity of the protective shell through the ring and the round cover.
[0021] In the above technical solution, further, the inner cavities of the protective shell 1 and the protective shell 2 are both rectangular structures, and the number of the elastic ropes is at least two.
[0022] In this technical solution, it is ensured that the elastic rope has sufficient tension to drive the round cover to squeeze the round ring, so that the round cover is always in close contact with the round ring.
[0023] In the above technical solution, further, the two ends of the spring one are tightly welded to the slider one and the protective shell two, the two ends of the spring two are tightly welded to the slider two and the protective shell two, and the two ends of the spring three are tightly welded to the slider three and the protective shell two.
[0024] In this technical solution, the structural stability of the slider 1 and the protective shell 2 is ensured, the structural stability of the slider 2 and the protective shell 2 is ensured, and the structural stability of the slider 3 and the protective shell 2 is ensured.
[0025] In the above technical solution, further, the surface of the baffle is provided with anti-slip grooves.
[0026] In this technical solution, when sliding the baffle to the right by hand, the friction between the hand and the baffle is increased to ensure that the baffle can be slid with light force.
[0027] The beneficial effects of the utility model are:
[0028] The liquid level gauge with a protective structure cooperates with protective shell 1, protective shell 2, glass sheet, limit frame 1, slider 1, spring 1, damper 1, limit frame 2, slider 2, spring 2, damper 2, limit frame 3, slider 3, damper 3, spring 3 and baffle. When the liquid level gauge is hit, the impact force generated can be effectively buffered, thereby effectively protecting the liquid level gauge body and will not cause damage to the internal components of the liquid level gauge. When it is necessary to observe the liquid level gauge body, the baffle can be slid to the right by hand to observe the liquid level gauge body through the glass sheet. The baffle can protect the glass sheet, and in actual use, it can prevent the glass sheet from breaking when hit, thereby preventing harm to personnel. At the same time, it ensures that the liquid level gauge body can monitor the liquid level changes in real time even if it is hit, so that personnel can understand the changes in time and prevent serious economic losses to the enterprise.

[0045] Example 1:
[0046] See also Figure 1-9 As shown in the figure, this embodiment provides a liquid level gauge with a protective structure, including:
[0047] Protective shell 1 2, protective shell 2 3 is provided inside protective shell 1 2, and the liquid level gauge body 1 is fixedly installed in protective shell 2 3, with both ends of the liquid level gauge body 1 respectively passing through the top and bottom of protective shell 2 3 and both passing through the rear side of protective shell 1 2 and extending to the outside;
[0048] Two limit frames 5, both fixedly mounted on one side of the inner wall of the protective shell 2, and each having a slider 6 slidably mounted therein, one side of the slider 6 being fixedly mounted with a damper 8 fixed to one side of the protective shell 3, and a spring 7 being sleeved on the damper 8;
[0049] Two limit frames 2 9, both of which are fixedly mounted on the other side of the inner wall of the protective shell 1 2, and a slider 2 10 is slidably mounted in each of the limit frames 2 9, a damper 2 12 fixed to the other side of the protective shell 2 3 is fixedly mounted on one side of the slider 2 10, and a spring 2 11 is sleeved on the damper 2 12;
[0050] Two limit frames 3 13, both of which are fixedly mounted on the rear side of the inner wall of the protective shell 1 2, and each of which has a slider 3 14 slidably mounted therein. A damper 3 15 fixed to the rear side of the protective shell 2 3 is fixedly mounted on one side of the slider 3 14, and a spring 3 16 is sleeved on the damper 3 15;
[0051] Two slide grooves 22 are symmetrically opened in the protective shell 1 2 and located at the front side of the protective shell 2 3 , and a baffle 21 is slidably installed between the two slide grooves 22 .
[0052] Among them, during use, when the liquid level gauge body 1 is hit from the front, the impactor will directly hit the baffle 21, and the baffle 21 will apply the impact force to the protective shell 2. At the same time, the protective shell 2 will drive the slider 3 14 to move to the rear side of the protective shell 2 through the limit frame 3 13, and then the slider 3 14 will pull the damper 3 15 and one end of the spring 3 16 to move to the rear side of the protective shell 2 until the damper 3 15 and the spring 3 16 are stretched to their longest length. The protective shell 2 stops moving, and the spring 3 16 generates a large pulling force during the extension process. At the same time, the protective shell 2 will drive the limit frame 1 5 and the limit frame 2 9 They slide on slider 1 6 and slider 2 10 respectively. At the same time, the cooperation between damper 3 15 and spring 3 16 provides sufficient cushioning for protective shell 1 2 on the liquid level gauge body 1 to reduce shock, ensuring that the liquid level gauge body 1 is not subjected to the impact force and ensuring the integrity of the liquid level gauge body 1. At the same time, the two ends of spring 3 16 pull slider 3 14 and protective shell 2 3 closer to each other, and slider 3 14 and protective shell 2 3 squeeze damper 3 15 to shrink. At the same time, slider 3 14 also drives protective shell 1 2 to return to its original position. At the same time, protective shell 1 2 is reset on limit frame 2 9 and limit frame 1 5 respectively through slider 2 10 and slider 1 6.
[0053] When one side of the liquid level gauge body 1 is hit, the impactor will directly hit the protective shell 2. Subsequently, the impacted protective shell 2 will directly drive the slider 6 to squeeze the damper 8 and one end of the spring 7 to move toward the other side of the protective shell 2, until the damper 8 and the spring 7 are compressed to their shortest length and the protective shell 2 stops moving. The spring 7 generates a large elastic force during the compression process. At the same time, the protective shell 2 will drive the limit frame 29 to move toward the other side of the protective shell 2, and the limit frame 29 will drive the slider 210 to move toward the other side of the protective shell 2. The slider 210 then pulls the damper 212 and one end of the spring 211 to move toward the other side of the protective shell 2, until the damper 212 and the spring 211 are stretched to their longest length and the protective shell 2 Stop moving, and the spring 2 11 generates a large pulling force during the stretching process. At the same time, the protective shell 1 2 will also drive the limit frame 3 13 to slide on the slider 3 14. Subsequently, the elastic force generated by the spring 1 7 cooperates with the compressed damper 1 8 and the tension generated by the spring 2 11 and the stretched damper 2 12 to buffer and reduce shock, ensuring that the liquid level gauge body 1 will not be subjected to the impact force, ensuring the integrity of the liquid level gauge body 1. After the impact, under the tension of the spring 2 11, the two ends of the spring 2 11 respectively pull the slider 2 10 and the protective shell 2 3 closer to each other, and the slider 2 10 and the protective shell 2 3 will squeeze the damper 2 12 to shrink. At the same time, the slider 2 10 will also drive the protective shell 1 2 to return to its original position. At this time, the protective shell 1 2 drives the limit frame 3 13 to reset on the slider 3 14;
[0054] When the other side of the liquid level gauge body 1 is hit, the impactor will directly hit the protective shell 2, and then the impacted protective shell 2 will directly drive the slider 2 10 to squeeze the damper 2 12 and one end of the spring 2 11 to move toward one side of the protective shell 2, until the damper 2 12 and the spring 2 11 are compressed to their shortest length and the protective shell 2 stops moving, and the spring 2 11 generates a large elastic force during the compression process. At the same time, the protective shell 2 will drive the limit frame 15 to move toward one side of the protective shell 2, and the limit frame 15 will drive the slider 16 to move toward one side of the protective shell 2, and then the slider 6 will pull the damper 18 and one end of the spring 17 to move toward one side of the protective shell 2, until the damper 18 and the spring 17 are stretched to their longest length and the protective shell 2 stops. The movement is stopped, and the spring 17 generates a large pulling force during the stretching process. At the same time, the protective shell 12 also drives the limit frame 3 13 to slide on the slider 3 14. Subsequently, the elastic force generated by the spring 2 11 cooperates with the compressed damper 2 12 and the tension generated by the spring 17 and the stretched damper 8 to buffer and reduce shock, ensuring that the liquid level gauge body 1 will not be subjected to the impact force, ensuring the integrity of the liquid level gauge body 1. After the impact, under the tension of the spring 17, the two ends of the spring 17 respectively pull the slider 1 6 and the protective shell 2 3 closer to each other, and the slider 1 6 and the protective shell 2 3 will squeeze the damper 18 to shrink. At the same time, the slider 6 will also drive the protective shell 2 to return to its original position through the limit frame 5. At this time, the protective shell 2 drives the limit frame 3 13 to reset on the slider 3 14.
[0055] When it is necessary to observe the liquid level gauge body 1, the baffle 21 can be slid to the right by hand to observe the liquid level gauge body 1 to prevent harm to personnel. At the same time, it ensures that the liquid level gauge body 1 can monitor the liquid level changes in real time even if it is hit, so that personnel can understand the changes in time and prevent serious economic losses to the company.

[0061] Among them, during use, when the liquid level gauge body 1 is hit from the front, the protective shell 2 will drive the ring 17 to move to the rear side of the protective shell 2, and the ring 17 will squeeze the round cover 18, so that the round cover 18 slides on the liquid level gauge body 1. At the same time, the round cover 18 stretches the elastic rope 19, so that the elastic rope 19 stretches and generates a large elastic force. Subsequently, the elastic rope 19 and the spring three 16 will shrink. At the same time, under the tension of the elastic rope 19 and the spring three 16, one end of the elastic rope 19 pulls the round cover 18 to move and squeeze the ring 17, and makes the ring 17 squeeze the protective shell 2 to restore to its original position. At the same time, under the tension of the elastic rope 19 itself, the round cover 18 will be pulled to always be in close contact with the ring 17, ensuring that no dust will enter the protective shell 2 from between the round cover 18 and the ring 17;

[0076] Example 7:
[0077] This embodiment provides a liquid level gauge with a protective structure. In addition to the technical solutions of the above embodiments, it also has the following technical features: the surface of the baffle 21 is provided with anti-slip grooves.
[0078] When sliding the baffle 21 to the right with the hand, the friction between the hand and the baffle 21 is increased to ensure that the baffle 21 can be slid with a slight force.
[0079] Working principle: During use, when the level gauge body 1 is hit from the front, the impactor will directly hit the baffle 21, and the baffle 21 will apply the impact force to the protective shell 2. At the same time, the protective shell 2 will drive the slider 3 14 to move to the rear side of the protective shell 2 through the limit frame 3 13, and then the slider 3 14 will pull the damper 3 15 and one end of the spring 3 16 to move to the rear side of the protective shell 2 until the damper 3 15 and the spring 3 16 are stretched to their longest length. 2 stops moving, and the spring three 16 generates a large pulling force during the extension process. At the same time, the protective shell one 2 drives the limit frame one 5 and the limit frame two 9 to slide on the slider one 6 and the slider two 10 respectively. At the same time, the protective shell one 2 also drives the ring 17 to move to the rear side of the protective shell one 2, and then the ring 17 squeezes the round cover 18, so that the round cover 18 slides on the liquid level meter body 1. At the same time, the round cover 18 stretches the elastic rope 19, so that the elastic rope 19 stretches and generates a large elastic force. Subsequently, the elastic rope 19 The spring 3 16 will shrink, and the cooperation of the damper 3 15 and the spring 3 16 makes the protective shell 1 2 get enough buffering on the liquid level gauge body 1 to reduce shock, ensuring that the liquid level gauge body 1 will not be subjected to the impact force, ensuring the integrity of the liquid level gauge body 1. At the same time, under the pulling force of the elastic rope 19 and the spring 3 16, one end of the elastic rope 19 pulls the round cover 18 to move and squeeze the ring 17, and makes the ring 17 squeeze the protective shell 1 2 to restore to its original position, and the two ends of the spring 3 16 pull the slider 3 1 4 and protective shell 2 3 approach each other, and slider 3 14 and protective shell 2 3 squeeze damper 3 15 to shrink. At the same time, slider 3 14 also drives protective shell 1 2 to return to its original position. At the same time, under the tension of elastic rope 19, round cover 18 is pulled to always keep close contact with ring 17, ensuring that no dust enters protective shell 1 2 from between round cover 18 and ring 17. At this time, protective shell 1 2 is reset on limit frame 2 9 and limit frame 1 5 respectively through slider 2 10 and slider 1 6;
[0080] When one side of the liquid level gauge body 1 is hit, the impactor will directly hit the protective shell 2, and then the hit protective shell 2 will directly drive the slider 6 to squeeze the damper 8 and one end of the spring 7 to move toward the other side of the protective shell 2, until the damper 8 and the spring 7 are compressed to their shortest length and the protective shell 2 stops moving, and the spring 7 generates a large elastic force during the compression process. At the same time, the protective shell 2 will drive the limit frame 29 to move toward the other side of the protective shell 2, and the limit frame 29 will drive the slider 210 to move toward the other side of the protective shell 2, and then the slider 210 will pull the damper 212 and one end of the spring 211 to move toward the other side of the protective shell 2, until the damper 212 and the spring 211 are stretched to their longest length and the protective shell 2 stops moving, and the spring 211 is at During the stretching process, a large pulling force is generated. At the same time, the protective shell 12 will also drive the limit frame 3 13 to slide on the slider 3 14. At the same time, the protective shell 12 will also drive the ring 17 to slide in the round cover 18. Subsequently, the elastic force generated by the spring 17 cooperates with the compressed damper 18 and the tension generated by the spring 2 11 and the stretched damper 2 12 to buffer and reduce shock, ensuring that the liquid level gauge body 1 will not be subjected to the impact force and ensuring the integrity of the liquid level gauge body 1. After the impact, under the tension of the spring 2 11, the two ends of the spring 2 11 respectively pull the slider 2 10 and the protective shell 2 3 closer to each other, and the slider 2 10 and the protective shell 2 3 will squeeze the damper 2 12 to shrink. At the same time, the slider 2 10 will also drive the protective shell 1 2 to return to its original position. At this time, the protective shell 1 2 drives the limit frame 3 13 to reset on the slider 3 14;
[0081] When the other side of the liquid level gauge body 1 is hit, the impactor will directly hit the protective shell 2, and then the impacted protective shell 2 will directly drive the slider 2 10 to squeeze the damper 2 12 and one end of the spring 2 11 to move toward one side of the protective shell 2, until the damper 2 12 and the spring 2 11 are compressed to their shortest length, and the protective shell 2 stops moving, and the spring 2 11 generates a large elastic force during the compression process. At the same time, the protective shell 2 will drive the limit frame 15 to move toward one side of the protective shell 2, and the limit frame 15 will drive the slider 16 to move toward one side of the protective shell 2, and then the slider 6 will pull the damper 18 and one end of the spring 17 to move toward one side of the protective shell 2, until the damper 18 and the spring 17 are stretched to their longest length, and the protective shell 2 stops moving, and the spring 7 is stretched. During the impact, a large pulling force is generated. At the same time, the protective shell 12 also drives the limit frame 3 13 to slide on the slider 3 14. At the same time, the protective shell 12 also drives the ring 17 to slide in the round cover 18. Subsequently, the elastic force generated by the spring 2 11 cooperates with the compressed damper 2 12 and the tension generated by the spring 17 and the stretched damper 8 to buffer and reduce shock, ensuring that the liquid level gauge body 1 will not be subjected to the impact force and ensuring the integrity of the liquid level gauge body 1. After the impact, under the tension of the spring 17, the two ends of the spring 17 respectively pull the slider 1 6 and the protective shell 2 3 closer to each other, and the slider 1 6 and the protective shell 2 3 will squeeze the damper 18 to shrink. At the same time, the slider 6 will also drive the protective shell 2 to return to its original position through the limit frame 5. At this time, the protective shell 2 drives the limit frame 3 13 to reset on the slider 3 14.
[0082] When it is necessary to observe the liquid level gauge body 1, slide the baffle 21 to the right by hand to observe the liquid level gauge body 1 through the glass sheet 4. The baffle 21 can protect the glass sheet 4 and prevent the glass sheet 4 from breaking when it is hit in actual use, thereby preventing harm to personnel. At the same time, it ensures that the liquid level gauge body 1 can monitor the liquid level changes in real time even if it is hit, so that personnel can understand the changes in time and prevent serious economic losses to the company.
