[0028] A radioactive level gauge mainly consists of three parts: a radioactive source, a detector, and electronic instruments. The radioactive source is classified into sealed radioactive sources and unsealed radioactive sources according to its sealing status. Level gauges used in industrial production all use sealed radioactive sources. The detectors include ionization chambers, Geiger counters, and scintillation crystal detectors. The electronic instruments consist of pulse amplifiers, compensation circuits, conversion and display units, and power supply sections. Most manufacturers integrate the electronic instruments and detectors into one unit, which is called a detection system.

[0029] While radioactive level gauges offer high precision and reliability in harsh industrial environments, their installation process is relatively cumbersome. Precise measurement and positioning are required during installation to ensure the accurate placement of the radiation source and detector, increasing complexity and time consumption. Furthermore, the use and maintenance of radioactive level gauges require professional personnel, including regular inspection, calibration, and maintenance to ensure stable measurement accuracy and performance. These cumbersome installation and usage steps not only increase manpower and time costs but also limit the flexibility and convenience of radioactive level gauges in certain application scenarios.

[0030] Based on this, the present invention proposes a portable installation device. Please refer to [link / reference]. Figure 1In one embodiment of this utility model, the portable installation device 100 includes a fixed cylinder 1, a movable member 2, a locking structure 3, and an unlocking member 4. The fixed cylinder 1 is used to fix the device to be installed in the installation position. The fixed cylinder 1 has an installation groove 11, and the inner side wall of the installation groove 11 is provided with at least one limiting hole 12. The movable member 2 is used to fix the device to be installed. The movable member 2 is slidably installed in the installation groove 11 along the depth direction of the installation groove 11. The locking structure 3 includes at least one limiting block 31 and a locking member 32. The multiple limiting blocks 31 are slidably installed in the multiple devices to be installed. The limiting hole 31 extends partially into the mounting groove 11 or retracts into each of the limiting holes 12. Along the groove direction close to the mounting groove 11, the end face of the limiting block 31 is inclined away from the movable member 2. The locking member 32 is fixedly installed on the movable member 2 to engage with the limiting block 31 when each of the limiting blocks 31 extends into the mounting groove 11. The unlocking member 4 is slidably installed on the movable member 2 along the depth direction of the mounting groove 11 and is located on the side of the locking member 32 away from the bottom of the mounting groove 11, so as to push each of the locking members 32 to retract into the limiting hole 12.

[0031] The technical solution of this utility model is to detachably install the device to be installed in the installation position by sliding the movable part 2 along the depth direction of the installation groove 11 into the installation groove 11. During installation, the limiting block 31 extends into the installation groove 11 and engages with the locking part 32. During disassembly, the sliding unlocking part 4 pushes the limiting block 31 back into the limiting hole 12 on the inclined end face of the unlocking part 4 to achieve disassembly. This simplifies the installation steps of the device and allows for quick disassembly and installation of the device.

[0032] The limiting block 31 has two states: partially extending into the mounting groove 11 or retracting into the limiting hole 12. During disassembly, it switches to the retracted state, achieved by the shape of its end face and the engagement of the unlocking member 4. During installation, the limiting block 31 switches to the partially extended state into the mounting groove 11, which can be implemented in several ways: In one embodiment, the limiting block 31 is positioned through the limiting hole 12. When installation is required, the movable member 2 is inserted into the mounting groove 11 at a specified depth, and then the limiting block 31 is directly engaged with the locking member 32 by manual pressing.

[0033] In one embodiment of this utility model, the locking structure 3 further includes an elastic element 33 disposed between each of the locking members 32 and the inner wall of the limiting hole 12. The elastic element 33 is in a compressed state, and the limiting block 31 has an initial position where it partially extends into the mounting groove 11. Thus, the state of the limiting block 31 is switched by the elastic element 33. The limiting block 31 has an initial position where it partially extends into the mounting groove 11, and the elastic element 33 is in a compressed state. Therefore, when not installed and when installed, the limiting block 31 is in a state where it partially extends into the mounting groove 11, and it can automatically reset after installation and disassembly.

[0034] It should be noted that the elastic element 33 can be disposed between the locking element 32 and the inner wall of the limiting hole 12 in multiple ways: In one embodiment, the elastic element 33 is sleeved on the limiting block 31, with one end of the elastic element 33 away from the mounting groove 11 fixedly connected to the limiting block 31, and the other end fixedly disposed on the inner wall of the limiting hole 12; In another embodiment, the diameter of the limiting hole 12 is reduced at both ends away from the middle of the limiting hole 12, one side of the elastic element 33 abuts against the stepped surface of the limiting hole 12 facing the movable member 2, the limiting block 31 abuts against the other side of the elastic element 33, and the other side of the limiting block 31 abuts against the stepped surface of the limiting hole 12 away from the movable member 2.

[0035] Furthermore, to prevent the limiting block 31 from coming out of the limiting hole 12 under the action of elastic force, a first stop is provided at the end of the limiting hole 12 away from the movable member 2. The limiting block 31 passes through the first stop and is inserted into the limiting hole 12. A second stop is provided at the end of the limiting block 31 away from the movable member 2. When the limiting block 31 is about to come out of the limiting hole 12 into the mounting groove 11 under the action of elastic force, the first stop and the second stop abut against each other to prevent it from coming out.

[0036] In one embodiment of the present invention, the elastic member 33 is sleeved on the locking member 32, one end of the elastic member 33 away from the mounting groove 11 is fixedly connected to the locking member 32, and the other end is fixedly disposed on the inner wall of the limiting hole 12.

[0037] In one embodiment of this utility model, the locking member 32 is sleeved on the movable member 2, and the outer circumference of the locking member 32 gradually decreases along the direction close to the bottom of the mounting groove 11. Thus, when the movable member 2 is inserted into the mounting groove 11, the outer circumference of the locking member 32 gradually decreases, and the limiting block 31 gradually retracts into the limiting hole 12 under the action of the elastic member 33, so that the locking member 32 and the limiting member are tightly fitted together. When the movable member 2 reaches the predetermined position, the locking member 32 and the limiting block 31 are completely engaged.

[0038] In one embodiment of this utility model, the unlocking member 4 is arranged around the movable member 2, and the outer circumference of the locking member 32 gradually increases in size along the direction close to the bottom of the mounting groove 11. Furthermore, the end faces of the unlocking member 4 and the locking member 32 that are close to each other have the same shape and size. Thus, when the unlocking member 4 moves towards the locking member 32, it pushes the limiting block 31 to gradually retract into the limiting hole 12, causing the locking member 32 and the unlocking member 4 to fit tightly together, achieving the unlocking function. Then, the movable member 2 can be smoothly pulled out of the mounting groove 11, ensuring simple and safe operation.

[0039] In one embodiment of this utility model, the inner sidewall of the mounting groove 11 is provided with a plurality of limiting holes 12, which are evenly arranged at intervals along the circumference of the mounting groove 11. This improves the applicability and flexibility of the mounting groove 11, ensures that the movable part 2 can be stably fixed in different positions, and further enhances the stability and durability of the overall structure.

[0040] Please see Figure 2 and Figure 3 This utility model also proposes a radioactive level gauge, which includes a mounting plate 200, a level gauge body 300, and at least one portable mounting device 100 as described above. The mounting plate 200 is used to fix the gauge in the mounting position. The portable mounting device 100 includes a fixing cylinder 1, a movable part 2, a locking structure 3, and an unlocking part 4. The fixing cylinder 1 is fixedly mounted on the mounting plate 200, and the fixing cylinder 1 has a mounting groove 11. At least one limiting hole 12 is provided on the inner side wall of the mounting groove 11. The movable part 2 is fixedly mounted on the back of the level gauge body 300 so that the level gauge body 300 can be detachably mounted on the mounting plate 200. The movable part 2 is slidably mounted in the mounting groove 11 along the depth direction of the mounting groove 11. The locking structure 3 includes at least one limiting block 31 and a locking member 32. The multiple limiting blocks 31 are slidably installed in the multiple limiting holes 12 to partially extend into the mounting groove 11 or retract into each of the limiting holes 12. Along the groove direction close to the mounting groove 11, the end face of the limiting block 31 is inclined away from the movable member 2. The locking member 32 is fixedly installed on the movable member 2 to engage with the limiting block 31 when each of the limiting blocks 31 extends into the mounting groove 11. The unlocking member 4 is slidably installed on the movable member 2 along the depth direction of the mounting groove 11 and is located on the side of the locking member 32 away from the bottom of the mounting groove 11, so as to push each of the locking members 32 to retract into the limiting hole 12. The specific structure of this portable mounting device 100 refers to the above embodiments. Since the radioactive level gauge adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.

[0041] In one embodiment of this utility model, the emissive level gauge further includes a support block 400, which is mounted on the mounting plate 200, with its end face away from the mounting plate 200 abutting against the back of the level gauge body 300. Thus, the support block 400 effectively distributes the weight of the level gauge body 300, reduces the stress on the mounting groove 11, extends its service life, and ensures that the level gauge body 300 remains horizontal and stable during measurement, thereby improving measurement accuracy.

[0042] In one embodiment of this utility model, a slide rail is provided on the end face of the support block 400 away from the mounting plate 200, and a slider adapted to the slide rail is provided on the back side of the level gauge body 300. Thus, the tight engagement between the slider and the slide rail makes the installation and disassembly of the level gauge body 300 smoother, avoids wear caused by friction, and further improves the reliability and service life of the device.

[0043] In one embodiment of this utility model, the groove opening of the mounting groove 11 is set downwards. When the limiting block 31 extends into the mounting groove 11, the locking member 32 is located above the limiting block 31 and engages with the limiting block 31. Thus, under the action of gravity, the locking member 32 and the limiting block 31 are tightly fitted together to achieve engagement. When disassembly is required, the radioactive level gauge and the movable part 2 are lifted upwards, the unlocking member 4 pushes the locking member 32 back into the limiting hole 12, and then the level gauge body 300 is pulled downwards to easily complete the disassembly, ensuring simple and efficient operation and convenient maintenance.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
