Description

Technical Field

[0001] The utility model belongs to the technical field of radar level gauges, and in particular relates to a spherical radar level gauge protection device. Background Art

[0002] Radar level meter is a general-purpose radar level meter. It is a measuring instrument based on the time travel principle. Radar waves run at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits a high-frequency pulse that propagates at the speed of light in space. When the pulse encounters the surface of the material, it is reflected back and received by the receiver in the meter, and the distance signal is converted into a level signal. Since radar level meters are often used in industry to measure acidic, alkaline and some corrosive liquids, their working environment is relatively harsh, so a corresponding protection device is urgently needed to protect the radar level meter.

[0003] For example, a Chinese patent with publication number CN205175502U discloses a liquid level gauge protection device, which relates to the field of liquid level monitoring technology; the device comprises two symmetrical angle steels, which are placed opposite to each other with a gap in the middle; the interior of the angle steel is arc-shaped, and an anti-slip device is provided on the arc surface; two connecting plates are provided at the upper and lower ends of the angle steel, and through holes are provided on the connecting plates; screws pass through the corresponding connecting plates of the two angle steels from the through holes, which has a simple structure, is easy to disassemble and assemble, protects the liquid level gauge from damage, brings convenience to production, reduces replacement frequency, saves resources, reduces production costs, saves time and effort, and improves production efficiency.

[0004] This patent has some disadvantages when used, such as: the device in this patent only protects the level meter through symmetrically arranged angle steels, and its protection ability is weak. When it is hit by external force, the level meter may still be damaged. In addition, since the device cannot fully wrap the level meter, the level meter is in an external state, and the level meter is susceptible to corrosion from the external environment, etc., which reduces the service life of the level meter. In view of this, we propose a spherical radar level meter protection device. Utility Model Content

[0045] Embodiment 1:

[0046] See also Figure 1 - Figure 7 As shown, this embodiment provides a spherical radar level gauge protection device, including:

[0047] A liquid level meter body 1, a semicircular chassis 2 is symmetrically arranged at the bottom of the liquid level meter body 1, slots 3 are symmetrically opened on the chassis 2, a fixing component is arranged on one side of the slot 3, a top cover 11 is arranged directly above the liquid level meter body 1, support columns 12 are fixed on the lower surface of the top cover 11 and near the four corners, three side panels 13 and a side panel 2 14 are respectively fixed on the lower surface of the liquid level meter body 1 and located between the two support columns 12, a slot 15 is opened on the inner wall of the side panel 13, and a sliding hole 19 is opened on the side panel 13 and located at the center of the slot 15;

[0048] The fixing assembly includes: a T-shaped slot 4, the T-shaped slot 4 is provided on the inner wall of the slot 3, an insert block 5 is slidably connected in the T-shaped slot 4, a spring 6 is fixed between one end of the insert block 5 away from the slot 3 and the inner wall of the T-shaped slot 4, a fixing hole for accommodating the insert block 5 is provided at the bottom end of the support column 12, and one end of the insert block 5 is plugged into and matched with the fixing hole at the bottom end of the support column 12;

[0049] Three first buffer components, which are respectively located in corresponding slots 15 and are used to perform shock absorption and buffering on the liquid level meter body 1;

[0050] Three second buffer components, the three second buffer components are respectively located in the corresponding sliding holes 19, and are used to dampen the liquid level meter body 1

[0051] Four limiting components are respectively located on the peripheral sides of the four T-shaped slots 4 and are used to constrain the insert block 5 in the pulled-out state.

[0052] During installation, first place the liquid level meter body 1 at the position to be installed, fix the bottom flange of the liquid level meter body 1 to the installation point with bolts, then clamp the two chassis 2 on both sides of the flange at the bottom of the liquid level meter body 1, one on the left and one on the right, then insert the top cover 11, multiple support columns 12, multiple side panels 1 13 and side panels 2 14 downward to completely wrap the liquid level meter body 1. When the four support columns 12 are inserted into the slots 3 on the two chassis 2 below, the operator releases the corresponding limit assembly. At this time, under the elastic action of the spring 1 6, the insert block 5 slides to the side close to the slot 3 until it is inserted into the fixing hole at the bottom of the support column 12. At this time, the four support columns 12 are effectively fixed to the two chassis 2 below. Since the two chassis 2 are fixed to the liquid level meter body 1 The bottom of the device is clamped, so that the two chassis 2 and multiple side panels 1 13, side panels 2 14 and top cover 11 can fully wrap and protect the liquid level meter body 1. When the device is hit, the multiple first and second buffer components located on the side of the liquid level meter body 1 can reduce the impact force on the liquid level meter body 1, thereby protecting the liquid level meter body 1. It is worth adding that the multiple side panels 1 13, side panels 2 14 and top cover 11 in the device can be made of polycarbonate, and the four support columns 12 and the two chassis 2 can be made of stainless steel and aluminum alloy. In addition, a plurality of reserved holes are opened at the position corresponding to the output end of the liquid level meter body 1 on the side panel 2 14 to facilitate the external circuit to enter the inner cavity of the device and electrically connect with the liquid level meter body 1.

[0053] Through the top cover 11, the support column 12, the side panel 1 13, the side panel 2 14 and the bottom plate 2, the liquid level meter body 1 can be fully wrapped and protected, which reduces the direct impact of the harsh external environment on the liquid level meter body 1 and increases the service life of the liquid level meter body 1. In addition, by setting up multiple first buffer components and second buffer components and using two-stage buffer components for buffering, the collision force on the liquid level meter body 1 located inside the device when it is hit by an external force is reduced, which plays a good protective role on the liquid level meter body 1. Secondly, by providing a T-slot 4 and an insert block 5, and using the elasticity of the sliding of the insert block 5 and the spring 1 6, the insert block 5 can quickly fix and disassemble the support column 12, so that the device is easy to install and disassemble, which changes the inconvenience of traditional devices that need to be fixed and installed by a large number of bolts.

[0054] Embodiment 2:

[0055] This embodiment provides a spherical radar level gauge protection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the first buffer component includes:

[0056] Two displacement plates 16 are symmetrically arranged and are both slidably installed in the slot 15. A spring 2 17 is symmetrically arranged between the two displacement plates 16, and the two ends of the spring 2 17 are respectively fixed to the inner side surfaces of the two displacement plates 16. An anti-collision plate 18 is arranged on the outer side of the two displacement plates 16, and the anti-collision plate 18 is rotatably matched with the two displacement plates 16.

[0057] Among them, when the device is impacted, the liquid level meter body 1 located inside will contact the anti-collision plate 18 on the opposite side of the collision force. The anti-collision plate 18 is forced to move toward the side close to the side plate 13 and squeeze the two displacement plates 16. In this process, one side of the two displacement plates 16 slides to both sides in an open state in the slot 15, and the two displacement plates 16 are in an eight-shaped shape in the vertical direction. The two springs 17 are stressed and in a stretched state. At the same time, an inward reaction force is generated, and the side of the two displacement plates 16 located in the slot 15 generates an inward contraction force, thereby reducing the force generated when the anti-collision plate 18 collides with the side plate 13 when it moves outward, and effectively protects the liquid level meter body 1 to avoid a more severe hard collision between the liquid level meter body 1 and the side plate 13 through the anti-collision plate 18.

[0058] By providing the first buffer component, the collision force generated between the anti-collision plate 18 and the side plate 13 when a collision occurs is reduced, and the elasticity of the spring 2 17 is used to offset the outward force generated when the anti-collision plate 18 is subjected to force, so that the collision force on the liquid level meter body 1 and the anti-collision plate 18 is greatly reduced, thereby providing effective buffering protection for the liquid level meter body 1.

[0059] Embodiment 3:

[0060] This embodiment provides a spherical radar level gauge protection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a rubber cushion is fixed to the outer side of the anti-collision plate 18.

[0061] The rubber cushion is provided to reduce the impact force between the liquid level meter body 1 and the anti-collision plate 18 .

[0062] Embodiment 4:

[0063] This embodiment provides a spherical radar level gauge protection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the second buffer component includes:

[0064] Spring three 20, spring three 20 is placed in the sliding hole 19, one end of the spring three 20 is provided with a buffer rod 21 slidably connected to the sliding hole 19, the inner wall of the side plate 13 and close to the sliding hole 19 is fixedly connected with a plug 22, one end of the buffer rod 21 passes through the plug 22 and extends to the inner side surface of the anti-collision plate 18, and a spring four 23 is sleeved on the buffer rod 21 and located on the outer side of the plug 22, and one end of the spring four 23 is fixed to the side wall of the plug 22.

[0065] Among them, when the anti-collision plate 18 squeezes the two displacement plates 16 to move outward, the inner side surface of the anti-collision plate 18 contacts one end of the buffer rod 21, and the buffer rod 21 slides toward the sliding hole 19 until the inner side surface of the anti-collision plate 18 contacts the spring four 23 and generates an extrusion force on the spring four 23. At the same time, under the elasticity of the spring four 23, the spring four 23 generates a reaction force on the anti-collision plate 18 to offset the force when the anti-collision plate 18 is displaced toward the side of the side plate 13. Combined with Example 2, the possibility of the anti-collision plate 18 directly contacting and colliding with the side plate 13 is greatly reduced.

[0066] By setting up a second buffer component in cooperation with the first buffer component, the force generated between the anti-collision plate 18 and the side plate 13 when a collision occurs is further weakened, thereby reducing the stress generated by the collision between the liquid level meter body 1 and the outer side plate 13, providing excellent protection for the liquid level meter body 1.

[0067] Embodiment 5:

[0068] This embodiment provides a spherical radar level gauge protection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the limit assembly includes:

[0069] The limiting groove 7 is arranged on the upper surface of the chassis 2 and close to the T-shaped groove 4. A limiting block 8 is rotatably installed in the limiting groove 7. The limiting block 8 is an integrally formed structure.

[0070] Among them, when the support column 12 needs to be pulled out or inserted from the slot 3, the operator can pull the plug block 5 so that the plug block 5 squeezes the spring 6, and the front end of the plug block 5 shrinks into the T-shaped slot 4. Then the operator rotates the limit block 8 so that the limit block 8 clamps the upper part of the plug block 5. At this time, the plug block 5 cannot be extended into the slot 3 again under the action of the limit block 8, and the support column 12 is effectively restrained. The operator can conveniently disassemble and install the support column 12.

[0071] By setting the limit assembly, great convenience is provided for the operator when installing the support column 12, the time required for installation is reduced, and the installation efficiency is improved.

[0073] This embodiment provides a spherical radar level gauge protection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a sealing ring 10 is installed on the side wall of the bottom flange of the level gauge body 1.

[0074] When the two chassis 2 are closed and clamp the flange at the bottom of the level gauge body 1, the presence of the sealing ring 10 can reduce the gap between the flange at the bottom of the level gauge body 1 and the two chassis 2, ensuring the airtightness of the inner cavity of the device and preventing the external environment from having adverse effects on the level gauge body 1.

[0075] Embodiment 7:

In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features: the inner wall of the chassis 2 is symmetrically provided with arc-shaped protrusions 9, and the side wall of the bottom end flange of the level gauge body 1 is provided with an annular groove that can accommodate multiple arc-shaped protrusions 9 to be embedded.

[0077] The two chassis 2 can perfectly fit with the flange at the bottom of the liquid level meter body 1 .

[0078] By providing an arc-shaped protrusion 9 and opening an annular groove on the flange at the bottom end of the liquid level gauge body 1, the chassis 2 and the liquid level gauge body 1 will not be displaced in the vertical direction when they are fixed. Combined with the four support columns 12 in Example 1, the two chassis 2 and various components on the side of the liquid level gauge body 1 can be stably fixed to the flange at the bottom of the liquid level gauge body 1.

[0079] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
