Description

A cable level gauge fixing device Technical Field

[0001] This utility model relates to the field of fixing device technology, and more specifically, to a cable level gauge fixing device. Background Technology

[0002] A liquid level gauge fixing device is an auxiliary structure or component used for installing, positioning, and fixing a liquid level measuring instrument. Its core function is to securely connect the liquid level gauge to the container being measured, ensuring that the liquid level gauge maintains the correct measuring position and attitude under various operating conditions, while withstanding environmental loads, ensuring the accuracy of liquid level measurement and the safety of equipment operation. However, when existing liquid level gauges measure the liquid level inside a stirred tank, the probe of the liquid level gauge cannot be effectively fixed due to the rotation of the stirrer, resulting in errors in the measurement data.

[0003] A search revealed that publication number CN220960232U discloses a cable fixing device for a guided wave radar level gauge, comprising a floating roof tank. A level gauge is fixedly installed at the upper end of the floating roof tank, and a waveguide is fixedly installed at the lower end of the level gauge. A sliding sleeve is fitted onto the waveguide, and a float plate is fixed to the sliding sleeve. A reflector is fixed at the lower end of the floating roof tank, and a cable is installed at the lower end of the level gauge. A limiting plate is fixed to the inner circumference of the waveguide, and a limiting hole is provided on the limiting plate. One end of the cable passes through the limiting hole and extends to the lower end of the limiting plate. Through the limiting plate and a counterweight, the cable is ensured to remain centered on the waveguide, preventing the cable from colliding with the waveguide when it tilts. This avoids inaccurate measurements caused by the cable swinging and colliding with the waveguide during use, thus improving the measurement accuracy of the level gauge. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] When existing cable level gauge fixing devices fix the level gauge to a device with an internal drive mechanism, such as the stirring mechanism inside a mixing tank, although the cable of the level gauge can withstand the impact force generated by the stirring mechanism when it rotates, the probe fixing part cannot withstand the liquid impact driven by the stirring mechanism. Moreover, when the stirring mechanism is running, the resistance exerted by the internal liquid on the stirring blades will cause the entire mixing tank to vibrate. This vibration will not only loosen the connection between the fixing device and the mixing tank, but also cause the internal components of the level gauge to shift and collide, thus making it unable to operate normally.

[0005] Therefore, a cable level gauge fixing device is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cable level gauge fixing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cable level gauge fixing device, comprising a clamping component, a fixing mechanism and a guiding component, wherein a guiding component is installed on the upper part of the inner wall of the fixing mechanism, and a clamping component is placed on the upper part of the guiding component.

[0008] Preferably, the fixing mechanism includes a shock-absorbing component, a housing component, and a support component, wherein the shock-absorbing component is installed on the inner wall side of the housing component, and the support component is installed on the side of the housing component.

[0009] Preferably, the clamping assembly includes a clamping half-ring, a sealing sponge strip, and a connecting assembly, wherein the sealing sponge strip is installed on the side of the clamping half-ring, and the connecting assembly is installed on the side of the clamping half-ring away from the sealing sponge strip.

[0010] Preferably, the connecting assembly includes an adjusting nut, a fixing screw, and an anti-slip washer, wherein the adjusting nut is mounted on the outer diameter surface of the fixing screw, and the anti-slip washer is placed on the side of the adjusting nut.

[0011] Preferably, the guide assembly includes a guide bearing, a rotating shaft, and a limiting plate, wherein the rotating shaft is mounted on the side of the guide bearing, and the limiting plate is mounted on the outer diameter surface of the rotating shaft.

[0012] Preferably, the shock-absorbing component includes a damper, a spring, and a mounting post, wherein the spring is placed on the outer diameter surface of the damper, and the mounting post is mounted on the side of the spring.

[0013] Preferably, the housing assembly includes a baffle plate, a guide post, and a housing, with the housing mounted above the baffle plate and the guide post mounted below the housing.

[0014] Preferably, the bracket assembly includes a connecting block, a shock-absorbing pad, and a mounting block, wherein the shock-absorbing pad is mounted on the side of the connecting block, and the mounting block is mounted on the side of the connecting block away from the shock-absorbing pad.

[0015] Preferably, a dial indicator is placed below the mounting block, and a fixing rod is placed on the outer diameter surface of the dial indicator, and a fixing pin is installed on the side of the fixing rod.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with the prior art, this cable level gauge fixing device absorbs the vibration generated by the mixing tank during use through the shock-absorbing component, thereby protecting the level gauge. When the internal mechanism of the mixing tank is running, the vibration is transmitted to the inside of the fixing device through the outer shell component. The spring will respond quickly to the impact force first and buffer some of the energy through deformation. Then the damper starts to play its role, gradually dissipating the energy stored in the spring deformation process and the energy generated by subsequent vibration. Thus, the impact of the vibration generated by the mixing tank during operation on the level gauge is controlled within the range that does not damage the internal components of the level gauge.

[0018] 2. Compared with the prior art, this cable level gauge fixing device fixes the gauge hammer to the fixing rod, and the fixing rod is fixed in the tank by a horizontal fixing method. This fixing method reduces the lateral pressure on the fixing rod when the stirring mechanism stirs the liquid, so that the gauge hammer can be firmly fixed in the stirring tank. When the stirring tank stirs the liquid, the liquid will also impact the lower side of the fixing device. The guide plate, through its external arc design, disperses the impact of the liquid on the outer shell assembly, preventing the repeated impact of the liquid on the outer shell assembly during long-term use of the stirring tank, thus preventing the fixing device and the storage tank installation parts from loosening.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiments

[0025] As shown in Figures 1 to 4, a cable level gauge fixing device includes a clamping assembly 1, a fixing mechanism 2, and a guide assembly 3. The guide assembly 3 is installed on the upper part of the inner wall of the fixing mechanism 2, and the clamping assembly 1 is placed on top of the guide assembly 3.

[0026] Specifically: When a worker needs to fix a cable level gauge to a liquid mixing tank to detect the liquid level inside, the fixing mechanism 2 of the fixing device needs to be divided into two parts by a snap-fit. The cable level gauge is placed in the clamping assembly 1, and then clamped in the middle of the fixing mechanism 2 using the clamping assembly 1. The cable of the cable level gauge is placed in the placement chamber below the clamping assembly 1. Then, the end of the cable not connected to the level gauge is passed through the guide assembly 3 through the small hole on the placement chamber, and wrapped around the guide assembly 3 once. This prevents the mechanism driving the level gauge cable from blocking the cable outlet hole below the fixing mechanism 2 when the cable is being driven to measure the liquid level in the mixing tank. This prevents the cable from exiting normally from the outlet hole, thus affecting the measurement of the liquid level in the mixing tank. Example

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, as shown in Figures 1 to 4. For details, please refer to the following description:

[0028] In a preferred embodiment, the fixing mechanism 2 includes a shock-absorbing component 4, a housing component 5, and a bracket component 6. The shock-absorbing component 4 is bolted to the inner side of the housing component 5, and the bracket component 6 is bolted to the side of the housing component 5. When the worker needs to install and fix the level gauge into the fixing device, the housing component 5 needs to be divided into two parts by a snap fastener. Then, the level gauge is fixed in the housing component 5 by the clamping component 1, and the display screen of the level gauge protrudes from the top of the housing component 5. At this time, the worker needs to reconnect the housing component 5 by the snap fastener and connect the fixing mechanism 2 and the level gauge together to the top of the mixing tank by the bracket component 6. The shock-absorbing component 4 can absorb the vibration generated when the internal mechanism of the mixing tank is running, preventing the vibration from affecting the measurement data of the level gauge.

[0029] In a preferred embodiment, the clamping assembly 1 includes a clamping half-ring 7, a sealing sponge strip 8, and a connecting assembly 9. The sealing sponge strip 8 is bonded to the side of the clamping half-ring 7, and the connecting assembly 9 is installed on the side of the clamping half-ring 7 away from the sealing sponge strip 8. When a worker needs to use the clamping assembly 1 to fix the level gauge, he needs to place the level gauge between the two clamping half-rings 7, and then twist the connecting assembly 9 to shorten the distance between the two clamping half-rings 7, thereby clamping the level gauge. When the clamping half-ring 7 clamps the level gauge, the sealing sponge strip 8 bonded inside it will deform to fill the gap between the clamping half-ring 7 and the level gauge.

[0030] In a preferred embodiment, the connecting assembly 9 includes an adjusting nut 10, a fixing screw 11, and an anti-slip washer 12. The adjusting nut 10 is mounted on the outer diameter surface of the fixing screw 11, and the anti-slip washer 12 is placed on the side of the adjusting nut 10. When the worker needs to clamp the level gauge using the clamping assembly 1, he / she first passes the fixing screw through the two clamping half-rings 7, and then passes the anti-slip washer 12 through the fixing screw 11 and places it on the outer diameter surface. At this time, the worker needs to install the adjusting nut 10 onto the fixing screw 11 and tighten the adjusting nut 10 of the connecting assembly 9 with a wrench to shorten the distance between the clamping half-rings 7, so that the clamping assembly 1 can clamp the level gauge.

[0031] In a preferred embodiment, the guide assembly 3 includes a guide bearing 13, a rotating shaft 14, and a limiting plate 15. The rotating shaft 14 is mounted on the side of the guide bearing 13, and the limiting plate 15 is mounted on the outer diameter surface of the rotating shaft 14. When the worker places the cable of the level gauge into the placement chamber, the part of the cable not connected to the level gauge needs to be passed through the cable outlet hole below the placement chamber. Then, the cable is wrapped around the area of ​​the rotating shaft 14 limited by the limiting plate 15, and then the cable is allowed to come out from the cable outlet hole below the housing assembly 5. Since the rotating shaft 14 is connected to the housing assembly 5 through the guide bearing 13, when the cable needs to extend outward, the rotating shaft 14 and the cable will also rotate, thereby playing a role in organizing the cable and preventing the cable from blocking the cable outlet hole of the housing assembly 5.

[0032] In a preferred embodiment, the shock-absorbing component 4 includes a damper 16, a spring 17, and a mounting post 18. The spring 17 is placed on the outer diameter surface of the damper 16, and the mounting post 18 is mounted on the side of the spring 17. When the internal mechanism of the mixing tank is running, the vibration is transmitted to the inside of the fixing device through the outer shell component 5. The spring 17 will first respond quickly to the impact force and buffer some of the energy through deformation. Then the damper 16 will start to play its role, gradually dissipating the energy stored in the deformation of the spring 17 and the energy generated by subsequent vibration. The mounting post 18 connects the shock-absorbing component 4 and the clamping component 1. The damper 16 is of model M4-M12. It provides a stable resistance torque during rotation through a viscous damping mechanism, consumes vibration energy, and suppresses rapid rotation or impact, thereby realizing the vibration reduction and stable control of precision equipment.

[0033] In a preferred embodiment, the outer casing assembly 5 includes a baffle plate 19, a guide post 20, and a housing 21. The housing 21 is mounted above the baffle plate 19, and the guide post 20 is mounted on the inner wall of the housing 21. When the operator starts the mechanism inside the mixing tank, the liquid inside the mixing tank will shake from side to side due to vibration and impact the outer casing assembly 5 of the fixing device. The baffle plate 19 disperses the impact of the liquid on the outer casing assembly 5 through its external arc design. The housing 21 can provide protection for the fixing device, and the guide post 20 can provide an outlet to the outside for the cable placed inside the fixing device.

[0034] In a preferred embodiment, the support assembly 6 includes a connecting block 22, a shock-absorbing pad 23, and a mounting block 24. The shock-absorbing pad 23 is mounted on the side of the connecting block 22, and the mounting block 24 is mounted on the side of the connecting block 22 away from the shock-absorbing pad 23. When the worker needs to fix the support assembly 6 above the mixing tank, he needs to use bolts to connect the support assembly 6 to the upper end of the mixing tank, and the connecting block 22 connects the mounting block 24 and the shock-absorbing pad 23.

[0035] In a preferred embodiment, a dial indicator 25 is placed below the mounting block 24, and a fixing rod 26 is placed on the outer diameter surface of the dial indicator 25. A fixing pin 27 is installed on the side of the fixing rod 26. The worker needs to fix the dial indicator 25 to the fixing rod 26 by the fixing pin 27 and fix the fixing rod 26 to the bottom of the mixing tank.

[0036] The working process of this utility model is as follows: First, when a worker needs to fix the cable level gauge to the liquid mixing tank to detect the liquid level inside, the outer shell assembly 5 needs to be divided into two parts by a buckle. Then, the level gauge is fixed in the outer shell assembly 5 by the clamping assembly 1. When the worker needs to use the clamping assembly 1 to fix the level gauge, the level gauge needs to be placed between the two clamping half-rings 7. Then, the worker needs to first pass the fixing bolt of the connecting assembly 9 through the two clamping half-rings 7, and then pass the anti-slip pad 12 through the fixing screw 11 and place it on the outer diameter gauge. At this point, the worker needs to install the adjusting nut 10 onto the fixing screw 11 and tighten the adjusting nut 10 of the connecting assembly 9 with a wrench to shorten the distance between the clamping half rings 7 and clamp the level gauge. When the clamping half ring 7 clamps the level gauge, the sealing sponge strip 8 bonded inside it will deform to fill the gap between the clamping half ring 7 and the level gauge. After the level gauge is fixed using the clamping assembly 1, the display screen of the level gauge needs to be exposed from the top of the housing assembly 5, and then the cable of the cable level gauge is placed into the clamping assembly. The cable is placed in the storage compartment below component 1, and one end of the cable connected to the level gauge is passed through the guide assembly 3 through the small hole on the storage compartment. Then, the cable is wrapped around the area of ​​the rotating shaft 14, which is limited by the limiting plate 15, and then the cable comes out from the cable outlet hole below the housing assembly 5. Since the rotating shaft 14 is connected to the housing of the housing assembly 5 through the guide bearing 13, when the cable needs to be extended due to insufficient distance, the rotating shaft 14 will rotate with the cable, thereby tidying up the cable and preventing the cable from blocking the cable outlet hole of the guide post 20. After the level gauge is installed on the fixing device... The fixing device needs to be fixed to the top of the mixing tank. The worker uses bolts to connect the bracket assembly 6 to the upper end of the mixing tank and uses sealing gaskets to seal the fixing point. The connecting block 22 connects the mounting block 24 and the anti-vibration pad 23. When the cable measures the liquid level in the mixing tank, the cable is placed in the fixing device in a wrong way, which blocks the cable outlet hole of the fixing device below the fixing mechanism 2, preventing the cable from coming out of the outlet hole normally. This affects the measurement of the liquid level in the mixing tank by the level gauge.

[0037] When the internal mechanism of the mixing tank is running, the vibration is transmitted to the inside of the fixing device through the outer shell assembly 5. The spring 17 will respond quickly to the impact force and buffer some of the energy through deformation. Then the damper 16 will start to play its role, gradually dissipating the energy stored in the deformation of the spring 17 and the energy generated by subsequent vibration. The mounting column 18 connects the shock-absorbing assembly 4 and the clamping assembly 1. When the mixing tank is stirring the liquid, the liquid will impact the lower side of the fixing device. The guide plate 19 disperses the impact of the liquid on the outer shell assembly 5 through its external arc design. In order to fix the gauge hammer 25 in the mixing tank and prevent damage to the gauge hammer 25 when the mixing tank is stirring the liquid, so that it can operate normally, the worker needs to fix the gauge hammer 25 to the fixing rod 26 with the fixing pin 27 and fix the fixing rod 26 to the bottom of the mixing tank. The above is the working principle of this cable level gauge fixing device.
