Description

Technical Field

[0001] This utility model relates to the field of rain measurement radar engineering technology, and in particular to a rain measurement radar transportation shock absorption mechanism and device. Background Technology

[0002] The dual-polarized phased array water conservancy rainfall radar is a high-performance water conservancy monitoring device based on X-band dual-polarized active phased array technology. It is mainly deployed in rivers, lakes, reservoirs, and other water conservancy projects to achieve refined rainfall monitoring and real-time alarms and warnings for disastrous rainstorms. This radar features a high refresh rate, high spatial resolution, and wide-area detection capability, effectively supporting the operational needs of water conservancy departments in disaster prevention and mitigation.

[0003] As a product of the integration of various high-end technologies such as modern phased array radar technology, very large-scale integrated circuits, all-solid-state transceiver components, high-speed computing, and high-speed optoelectronic communication, this radar is a high-precision electromechanical device. During transportation to the user's site, the equipment is susceptible to complex external excitations such as continuous bumps caused by uneven road surfaces and high-frequency vibrations caused by speed bumps. Currently, conventional transportation solutions typically use a single secondary rubber component as vibration damping material, which has limited vibration damping effect and is prone to aging and detachment. If large-amplitude vibrations are encountered during transportation, the energy without effective buffering will be directly transferred to the radar body, potentially causing abnormal internal hardware connections, affecting antenna array accuracy and system stability, and in extreme cases, even preventing the equipment from starting normally. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a vibration damping mechanism for transporting rain-measuring radar, which can effectively isolate vibrations and impacts during transportation, protect the precision components inside the radar and the accuracy of the antenna array, and ensure that the equipment can be put into stable operation upon arrival at the site.

[0005] This utility model also proposes a rain-measuring radar transportation shock absorption device.

[0006] According to a first aspect of the present invention, a rain-measuring radar transport shock absorption mechanism includes: a base having shock-absorbing grooves and shock-absorbing holes extending in a vertical direction, and a support surface provided on the top of the base; a first shock-absorbing unit extending in a vertical direction and embedded in the shock-absorbing groove, the top of the first shock-absorbing unit protruding from the support surface, the first shock-absorbing unit being configured to absorb high-frequency vibrations and small-amplitude shaking; a second shock-absorbing unit extending in a vertical direction and embedded in the shock-absorbing hole, the top of the second shock-absorbing unit protruding from the support surface, the second shock-absorbing unit being configured to absorb low-frequency vibrations and larger impacts; a bearing panel covering the support surface, the top of the first shock-absorbing unit and the second shock-absorbing unit, the bearing panel being configured to directly bear the radar load; and a locking assembly disposed on the base, the locking assembly being connected to the bearing panel, the locking assembly being configured to lock the bearing panel onto the base.

[0007] The system offers at least the following advantages: The base serves as the main support for the entire mechanism, with a support surface on its top. The base has damping grooves and holes extending vertically. A first damping unit is embedded in the damping groove, its top protruding from the support surface of the base, allowing it to preferentially contact and undergo elastic deformation under load. A second damping unit is also embedded in the damping hole, its top protruding from the support surface of the base. The second and first damping units work together to form a dual-redundant damping system. A load-bearing panel covers the base, the first damping unit, and the second damping unit, directly bearing the load of the radar equipment and transmitting the vibrations and impacts to the damping system below for cushioning. A locking assembly is located on the base and is configured to quickly lock the load-bearing panel to the base, preventing horizontal movement or detachment during transport, while also allowing for quick unlocking when unloading is required. This invention reliably locks the bearing panel onto a graded redundant vibration damping system composed of a first damping unit and a second damping unit using a locking assembly. The first damping unit handles high-frequency, small-amplitude vibrations, while the second damping unit absorbs low-frequency, large-amplitude impacts. The two work together to reduce the vibration energy transmitted to the radar body, thereby achieving effective attenuation of broadband vibration energy and providing effective vibration buffering and impact protection for the high-precision rain measuring radar.

[0022] Reference Figures 1 to 7This utility model discloses a shock absorption mechanism for transporting rain measuring radar, including a base 1, a first shock absorption unit 2, a second shock absorption unit 3, a bearing panel 4, and a locking assembly 5. The base 1 has a shock absorption groove 11 and a shock absorption hole 12 extending in the vertical direction, and a support surface 13 is provided on the top of the base 1. The first shock absorption unit 2 is embedded in the shock absorption groove 11 extending in the vertical direction, and the top of the first shock absorption unit 2 protrudes from the support surface 13. The first shock absorption unit 2 is configured to absorb high-frequency vibration and small-amplitude shaking. The second damping unit 3 is embedded in the damping hole 12 extending vertically. The top of the second damping unit 3 protrudes from the support surface 13. The second damping unit 3 is configured to absorb low-frequency vibrations and large impacts. The bearing panel 4 is covered on the support surface 13, the top of the first damping unit 2 and the second damping unit 3. The bearing panel 4 is configured to directly bear the radar load. The locking assembly 5 is disposed on the base 1 and connected to the bearing panel 4. The locking assembly 5 is configured to lock the bearing panel 4 onto the base 1.

[0023] Reference Figures 1 to 3 The base 1 serves as the main support for the entire mechanism, with a support surface 13 on its top. The base 1 has damping grooves 11 and damping holes 12 extending vertically. A first damping unit 2 is embedded in the damping groove 11, extending vertically, with its top protruding from the support surface 13 of the base 1, allowing it to preferentially contact and undergo elastic deformation under load. A second damping unit 3 is also embedded in the damping hole 12, extending vertically, with its top protruding from the support surface 13. The second damping unit 3 and the first damping unit 2 together form a dual-redundant damping system. A load-bearing panel 4 covers the top of the base 1, the first damping unit 2, and the second damping unit 3, directly bearing the load of the radar equipment and transmitting the vibrations and impacts to the damping system below for buffering. The locking assembly 5 is disposed on the base 1 and is configured to quickly lock the carrier panel 4 onto the base 1 to prevent it from moving horizontally or detaching during transportation, while also enabling quick unlocking when unloading is required.

[0024] This invention reliably locks the bearing panel 4 onto a graded redundant vibration damping system composed of a first damping unit 2 and a second damping unit 3 using a locking component 5. The first damping unit 2 handles high-frequency small-amplitude vibrations, while the second damping unit 3 absorbs low-frequency large-amplitude impacts. The two work together to reduce the vibration energy transmitted to the radar body, thereby achieving effective attenuation of broadband vibration energy and providing effective vibration buffering and impact protection for the high-precision rain measuring radar.

[0025] In some specific embodiments of this utility model, the top of the second damping unit 3 is not higher than the top of the first damping unit 2. For example... Figure 3As shown, the height difference between the first damping unit 2 and the second damping unit 3 realizes the sequential triggering mechanism of two-stage damping. Specifically, the first damping unit 2 responds to and filters high-frequency vibrations first. When the impact load exceeds the design threshold of the first damping unit 2, the second damping unit 3 immediately intervenes to deal with the large impact. The two work together and jointly form an efficient energy attenuation path.

[0026] In some specific embodiments of this utility model, the first damping unit 2 and the second damping unit 3 are arranged symmetrically. This arrangement ensures that when the damping system is subjected to complex loads, the first damping unit 2 and the second damping unit 3 can work together and in a balanced manner, thereby effectively improving the stability of the entire damping system.

[0027] like Figure 6 As shown, the base 1 has a hollow structure inside, with five damping grooves 11 and twelve damping holes 12. It should be noted that, as... Figure 3 As shown, the damping groove 11 has a closed bottom, while the damping hole 12 is a through hole penetrating the base 1 vertically. Specifically, the five damping grooves 11 include a central damping groove 112 located in the center of the base 1, and four peripheral damping grooves 113 evenly distributed around the central damping groove 112. A damping hole 12 is provided between any adjacent peripheral damping groove 113 and the central damping groove 112. Simultaneously, eight damping holes 12 are evenly arranged around the circumference within the annular region between the inner wall of the base 1 and the four peripheral damping grooves 113. The first damping unit 2 is embedded in the damping groove 11, and the second damping unit 3 is embedded in the damping hole 12, forming an overall distribution pattern with multi-axis symmetry.

[0028] It should be noted that the quantity, shape, and arrangement of the aforementioned damping grooves 11 and damping holes 12 are merely exemplary embodiments and are not intended to limit the scope of protection of this utility model. In other embodiments of this utility model, the specific quantity of damping grooves 11 and damping holes 12 can be increased or decreased according to actual load-bearing and vibration reduction requirements, and their arrangement can also adopt an array or other topological configurations that conform to mechanical distribution. Any structural modifications that utilize the graded redundancy vibration reduction principle disclosed in this utility model should be considered to fall within the scope of protection of this utility model.

[0029] In some specific embodiments of this utility model, the bottom end of the second shock-absorbing unit 3 is provided with an anti-slip part 31, which is configured to enhance the friction between the base 1 and the ground. For example... Figure 4 As shown, the anti-slip part 31 is a cylindrical protrusion structure arrayed on the bottom surface of the second shock-absorbing unit 3. Of course, the anti-slip part 31 can also be a corrugated protrusion or a functional layer made of a high-friction coefficient material, which is configured to effectively enhance the adhesion between the base 1 and the ground and prevent slippage during loading, unloading or transportation on slopes.

[0030] In some specific embodiments of this utility model, the first damping unit 2 includes a first rubber component 21, and the bottom of the damping groove 11 is provided with a protrusion 111 extending in the vertical direction, and the first rubber component 21 is sleeved on the protrusion 111.

[0031] like Figure 3 and Figure 5 As shown, in a preferred embodiment of this utility model, the first damping unit 2 includes a first rubber component 21, which is an elliptical hollow thin-walled high-damping structure with a wavy outer contour along the vertical direction. Correspondingly, the bottom of the damping groove 11 is provided with a protruding post 111 extending in the vertical direction. The first rubber component 21 is sleeved on the protruding post 111, and its bottom is attached to the base 1. Therefore, whether in the hoisting process or in the static placement state, it can be completely covered and fixed in the annular cylindrical cavity, thereby achieving precise positioning of the rubber pad and preventing the first rubber component 21 from shifting or falling off during vibration.

[0032] Furthermore, when the load is applied to the bearing panel 4, the first rubber component 21 preferentially bears the pressure and generates extrusion deformation. Its wave-shaped thin-walled structure simulates the mechanical characteristics of a spring, enabling it to achieve periodic large-amplitude reciprocating deformation under the support of the structural skeleton formed by the base 1. Thus, as the first-level vibration damping unit, it efficiently absorbs high-frequency vibration and small-amplitude shaking.

[0033] It should be noted that the first rubber component 21 is only one specific implementation of the first shock-absorbing unit 2 and is not a limitation on the scope of protection of this utility model. In other embodiments of this utility model, the first shock-absorbing unit 2 may also be a helical spring, a disc spring, a polyurethane elastomer, or other components with similar elastic recovery functions, which will not be further elaborated here.

[0034] In some specific embodiments of this utility model, the second damping unit 3 includes a second rubber component 32. The side of the second rubber component 32 is provided with an inwardly recessed groove 321. The wall of the damping hole 12 is provided with a boss 15 that matches the groove 321. The groove 321 and the boss 15 engage to limit the second rubber component 32 within the damping hole 12.

[0035] like Figure 4 and Figure 5As shown, the second damping unit 3 includes multiple second rubber parts 32, each of which is an independently molded rubber block, embedded in damping holes 12 at different positions within the base 1. Specifically, in the damping holes 12 located within the annular region between the inner wall of the base 1 and the four peripheral damping grooves 113, the end of the rubber block that connects to the side wall of the base 1 has an inwardly recessed groove 321. Two grooves 321 are arranged parallel to each other in the vertical direction and extend horizontally. Correspondingly, a boss 15 adapted to the groove 321 is formed on the wall of the damping hole 12. During installation, the rubber block is inserted into the damping hole 12 from top to bottom. The elastic deformation of the rubber material itself causes the groove 321 to engage with the boss 15 on the hole wall, thereby reliably fixing the rubber block within the damping hole 12. Similarly, the rubber block installed in the damping hole 12 between the outer damping groove 113 and the central damping groove 112 also has a horizontally extending groove 321, which is fixed by engaging with the boss 15 on the corresponding damping hole 12 wall. Thus, the interlocking structure of the groove 321 and the boss 15 provides stable installation positioning and anti-fall-off protection for the second damping unit 3, ensuring that it always maintains the preset position and damping function under vibration environment.

[0036] It should be noted that in other embodiments of this utility model, other mechanical fixing methods such as bonding, interference fit, screw fastening or modular buckle can also be used. Any similar structural design that can stably install the second rubber part 32 in the shock-absorbing hole 12 and prevent it from falling off should be considered to fall within the protection scope of the claims of this utility model.

[0037] In some specific embodiments of this utility model, the locking assembly 5 includes: a screw bolt 51, threadedly connected to the base 1; a compression spring 52, sleeved on the screw bolt 51; a limiting steel sleeve 53, sleeved on the screw bolt 51 and pressed against the lower end of the compression spring 52; and a rotating lever 54, fixedly connected to the limiting steel sleeve 53. When the screw bolt 51 is tightened, the compression spring 52 drives the limiting steel sleeve 53 to press the rotating lever 54 against the top of the bearing panel 4. When the screw bolt 51 is loosened, the rotating lever 54 is allowed to rotate to separate from the bearing panel 4.

[0038] like Figure 1 and Figure 7As shown, the base 1 has threaded holes along its vertical direction on its side wall. The screw 51 passes through these threaded holes to achieve a threaded connection with the base 1. A compression spring 52 and a limiting steel sleeve 53 are sequentially fitted onto the screw 51 from top to bottom. One end of the compression spring 52 abuts against the head of the screw 51, and the other end acts on the limiting steel sleeve 53. The lower end of the limiting steel sleeve 53 is fixedly connected to the rotating handle 54, forming a synchronously rotating linkage component. When the screw 51 is tightened, its axial displacement compresses the compression spring 52, which in turn presses the limiting steel sleeve 53 and the rotating handle 54 tightly onto the base 1, locking them in a locked state. When the screw 51 is loosened, the preload of the compression spring 52 is released, allowing the limiting steel sleeve 53 and the rotating handle 54 to rotate or displace relative to the base 1 under external force, thus unlocking them. Based on the above structure, during installation, the bearing panel 4 is placed on the support surface 13 of the base 1. The screw 51 is loosened to allow the rotating handle 54 to move freely, which is then rotated above the bearing panel 4. The screw 51 is then tightened, and the continuous downward pressure generated by the compression spring 52 presses the rotating handle 54 firmly against the surface of the bearing panel 4, thus reliably locking the bearing panel 4. During disassembly, simply loosen the screw 51 to release the clamping force, and rotate the rotating handle 54 away from the area above the bearing panel 4 to release the constraint on the bearing panel 4, achieving rapid separation. The locking assembly 5 of this invention enables rapid assembly and disassembly of the bearing panel 4, ensuring the stability and reliability of the bearing panel 4 in a vibration environment while locked, thereby improving the convenience and safety of the equipment during field transportation and hoisting operations.

[0039] In some specific embodiments of this utility model, the side wall of the base 1 extends upward to form a barrier 14, and the barrier 14 and the support surface 13 enclose each other to form a limiting groove whose shape is adapted to the bearing panel 4. The barrier 14 is configured to restrict the horizontal movement of the bearing panel 4.

[0040] like Figure 1 and Figure 2 As shown, the four corners of the sidewall of the base 1 extend upward to form L-shaped barriers 14. These barriers 14, together with the support surface 13 of the base 1, form a limiting groove that matches the shape of the bearing panel 4. When the bearing panel 4 is placed on the support surface 13, the L-shaped barriers 14 at the four corners can clamp and limit it from different directions, effectively restricting the movement of the bearing panel 4 in all directions in the horizontal plane.

[0041] Furthermore, a lateral groove is naturally formed in the gap area between two adjacent L-shaped barriers 14. The groove is configured to provide accommodating space for the locking assembly 5, allowing it to be compactly embedded within the contour of the base 1. In particular, the rotary lever 54 can rotate and be completely retracted into the groove in the unlocked state, thereby achieving complete avoidance of the support panel 4 and ensuring its smooth placement and removal. This embedded design ensures that the locking assembly 5 does not occupy external space when not in operation, and also avoids interference that may be caused by external protrusions during transportation or hoisting, thereby improving operational safety and convenience.

[0042] Reference Figure 8 This utility model also discloses a rain measuring radar transport shock absorption device, including a transport base frame 6 and a rain measuring radar transport shock absorption mechanism, wherein the transport base frame 6 is connected to the bearing panel 4, and the transport base frame 6 is configured to mount the entire radar unit.

[0043] Specifically, the transport base frame 6 serves as the main load-bearing structure of the radar unit, and its bottom is fixedly connected to the load-bearing panel 4. The transport base frame 6 adopts a rigid frame structure and has an installation interface that matches the base of the radar unit, providing stable support and reliable fixation for the radar equipment. The transport base frame 6 adopts a conventional load-bearing frame structure in the field, and its specific design and connection method are existing mature technologies, which will not be described in detail here.

[0044] The following reference Figures 1 to 8 The structure shown further illustrates the transport shock absorption device for this rain-measuring radar.

[0045] like Figure 8 As shown, the transport base 6 adopts a rigid frame structure, with a buffer 62 on its top that directly contacts the radar equipment. The transport base 6 has four legs, each connected to a rain-measuring radar transport shock absorption mechanism. Specifically, as... Figure 1 and Figure 2 As shown, the foot is fixedly connected to the bearing panel 4, the bearing panel 4 is placed on the support surface 13, and is locked to the base 1 by four locking structures provided on the side wall of the base 1.

[0046] like Figure 8 As shown, the transport base 6 adopts a rigid frame structure, with a buffer 62 on its top. This buffer 62 directly contacts the bottom surface of the radar equipment, providing stable support while preventing damage to the radar casing from rigid contact. The bottom of the transport base 6 has four legs 61, each connected to a rain-measuring radar transport shock absorption mechanism. Combined with... Figure 1 and Figure 2As shown, the support leg 61 is fixedly installed on the support panel 4. Specifically, during installation, the support panel 4 with the support leg 61 is placed on the support surface 13 of the base 1, so that the outline of the support panel 4 matches the limiting groove formed by the L-shaped enclosure 14 on the base 1, achieving initial positioning. Subsequently, the support panel 4 is locked by the locking components 5 provided on the four sides of the base 1, that is, the rotating handle 54 is rotated to the top of the support panel 4, and the compression spring 52 is compressed by tightening the screw bolt 51, so that the rotating handle 54 generates continuous downward pressure, thereby firmly pressing the support panel 4 onto the base 1, completing the assembly of the entire device. During vibration damping, the first damping unit 2 and the second damping unit 3 work together based on the principle of dual-level redundancy. Specifically, when high-frequency, small-amplitude vibrations occur during transportation, the first damping unit 2, embedded in the damping groove 11, takes priority in functioning. Its wave-shaped thin-walled structure absorbs and disperses vibration energy through elastic deformation. When encountering low-frequency, large-amplitude impacts, the second damping unit 3, embedded in the damping hole 12, further intervenes, providing additional buffer stroke and energy dissipation through the coordinated deformation of multiple independent rubber blocks. The technical solution of this utility model provides effective contact protection for radar equipment during transportation through the combination of a rigid frame and a buffer component 62. The four-point connected damping mechanism layout, combined with a graded vibration damping system, evenly distributes the radar load and effectively isolates various vibration impacts, ultimately providing a complete transportation protection solution for high-precision rain measuring radar.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
