Abstract
Description
Technical Field
[0001] This utility model relates to the field of receiver technology, and in particular to a combined mounting mechanism for a receiver. Background Technology
[0002] A receiver is a device used to receive and process signals. Its main function is to select the desired signal from a large number of signals and convert it into a usable form. It is widely used in many fields such as communication, broadcasting, radar, and navigation. In order to ensure that the receiver can be installed stably and flexibly in a specific location, a combined mounting mechanism is usually used to reliably fix the receiver. It may also have the function of adjusting the position and angle of the receiver to optimize the signal reception effect.
[0003] According to the search, the Chinese patent "A GNSS Receiver Installation Mechanism" authorized announcement number "CN218032357U" uses an L-shaped support rod, a connecting rod, a U-shaped clamping body, a spring, and a positioning body to clamp and install the GNSS receiver on the side of the base plate. The L-shaped support rod creates a gap between the receiver and the base plate, and an exhaust device is installed in the gap to dissipate heat and enhance the heat dissipation effect.
[0004] In the aforementioned application, because the U-shaped card connector contacts the side of the receiver, the heat on the side of the receiver is difficult to dissipate, thus affecting the heat dissipation effect on the side of the receiver.
[0005] Therefore, a combined mounting mechanism for receivers is proposed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a combined mounting mechanism for a receiver to solve the above-mentioned problems, thereby improving the problem that the heat from the side of the receiver is difficult to dissipate due to the contact of the U-shaped connector with the side of the receiver, which in turn affects the heat dissipation effect on the side of the receiver.
[0007] This utility model achieves the above-mentioned objective through the following technical solution: a combined mounting mechanism for a receiver, comprising: a mounting base, the top of which is rotatably connected to a support, and a fan disposed inside the support; and a mounting mechanism, comprising two abutments slidably connected to the inner wall of the support, two first springs fixedly connected to the ends of the abutments, the other ends of the first springs fixedly connected to the inner wall of the support, and limit frames slidably connected to both sides of the inner wall of the support. The first springs push the abutments to move and abut against the ends of the receiver's legs, thereby locking the receiver. The limit frames slide into the support, limiting the abutments and ensuring that the ends of the abutments stably abut against the ends of the receiver's legs, avoiding clamping the receiver from both sides. The fan, in conjunction with the mechanism, ensures effective heat dissipation for the receiver.
[0008] Preferably, the inner wall of the support is fitted with two filters, and the ends of the filters are fixedly connected to guide rods, the surfaces of which are engaged with the inner wall of the support. The filters protect the top and bottom of the support, preventing impurities from entering the fan surface through the open top and bottom of the support, thereby ensuring the fan's effective heat dissipation for the receiver.
[0009] Preferably, the inner wall of the support is slidably connected with two positioning blocks, the surfaces of which are engaged with the inner wall of the guide rod.
[0010] Preferably, a second spring is fixedly connected to one side of the positioning block, and the other end of the second spring is fixedly connected to the inner wall of the support. The elastic force of the second spring pushes the positioning block to engage with the guide rod, thereby locking both filters onto the support simultaneously, ensuring the protective effect of the filters on the fan.
[0011] Preferably, a connecting rope is fixedly connected to one side of the positioning block, and the other end of the connecting rope passes through and extends out of the inner wall of the support.
[0012] Preferably, a pull block is fixedly connected to the top end of the connecting rope. The pull block and the connecting rope work together to move the positioning block away from the guide rod, thereby releasing the lock on the filter screen and facilitating its disassembly and cleaning.
[0013] Preferably, the bottom of the support is fixedly connected to two limiting rods, and the inner wall of the limiting frame is slidably connected to the surface of the limiting rods.
[0014] The beneficial effects of this utility model are:
[0015] 1. The first spring pushes the abutment to move and abut against the end of the receiver's legs, thereby locking the receiver. The limit bracket slides into the support to limit the abutment, thus ensuring that the end of the abutment is stably abutting against the end of the receiver's legs. Compared with the existing method of clamping the receiver on both sides to install it on the mounting mechanism, this method avoids clamping the receiver on both sides by locking the end of the receiver's legs. With the help of the fan, the heat dissipation effect of the receiver is ensured.
[0016] 2. The top and bottom of the support are protected by a filter screen to prevent impurities from entering the fan surface through the open top and bottom of the support, thereby ensuring the fan's heat dissipation effect on the receiver. Attached Figure Description

[0022] 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 protection scope of the present utility model.
[0023] In practical implementation: such as Figure 1-4 As shown, a combined mounting mechanism for a receiver includes: a mounting base 1, with a support 2 rotatably connected to the top of the mounting base 1, and a fan 3 disposed inside the support 2; and a mounting mechanism 4, which includes two abutments 41 slidably connected to the inner wall of the support 2, two first springs 42 fixedly connected to the ends of the abutments 41, the other ends of the first springs 42 fixedly connected to the inner wall of the support 2, and limit frames 43 slidably connected to both sides of the inner wall of the support 2. The limit frames 43 are rubber components, and the motor on the fan 3 is mounted inside the support 2 by bolts.
[0024] When it is necessary to measure the land planning terrain, pull the two sets of support frames 41 away from each other, place the GNSS receiver's legs at the corresponding positions on the top of the support 2, loosen the support frames 41, and the elastic force of the first spring 42 pushes the support frames 41 to move and abut against the end of the receiver's legs. At this time, push the limiting frame 43 to slide into the support 2, so that the end of the limiting frame 43 abuts against the end of the support frame 41, thereby making the GNSS receiver stably installed on the support 2.
[0025] Mounting bracket 1 is installed on the tripod using bolts or other means, and the tripod is placed on the measurement point. The GNSS receiver is then positioned on the measurement point, centered, and leveled. After initialization, the receiver is powered on and initialized. Once initialization is complete, satellite signal acquisition begins, and information such as the coordinates, elevation, and measurement time of the measurement point is recorded. To improve measurement accuracy, each measurement point typically requires observation for a certain period of time. Generally, static measurements require observation for more than 30 minutes, and dynamic measurements also require sufficient observation time. After acquisition, the data in the GNSS receiver is transferred to the computer. Data transfer can be performed via data cable, Bluetooth, Wi-Fi, etc. The raw data transferred to the computer is preprocessed, including data format conversion, gross error removal, and cycle slip repair. The purpose of preprocessing is to improve data quality and provide a reliable data foundation for subsequent adjustment calculations and terrain modeling. Professional measurement adjustment software is used to perform adjustment calculations on the preprocessed data to determine the precise coordinates and elevation of the measurement points. Adjustment calculations can eliminate the influence of measurement errors and improve the accuracy and reliability of the measurement results.
[0026] Based on the coordinates and elevations of the measurement points obtained from the adjustment calculations, a topographic map is drawn using professional drawing software. The topographic map can intuitively reflect the topography of the measurement area, including information such as topographic relief, slope, and aspect. Using the three-dimensional coordinate data of the measurement points, a three-dimensional model of the terrain is generated. The three-dimensional terrain model can more intuitively display the true shape of the terrain, providing richer information for terrain analysis, engineering design, etc. A detailed measurement report is written, including the purpose of the measurement, measurement methods, measurement results, accuracy analysis, etc. The measurement report is one of the important results of topographic surveying work, and it can provide a reference for subsequent engineering construction, land planning, etc.
[0027] like Figure 4 As shown, two filter screens 44 are snapped onto the inner wall of the support 2. A guide rod 45 is fixedly connected to the end of each filter screen 44. The surface of the guide rod 45 is snapped onto the inner wall of the support 2. Two positioning blocks 46 are slidably connected to the inner wall of the support 2. The surface of the positioning blocks 46 is snapped onto the inner wall of the guide rod 45. A second spring 47 is fixedly connected to one side of each positioning block 46. The other end of the second spring 47 is fixedly connected to the inner wall of the support 2. A connecting rope 48 is fixedly connected to one side of each positioning block 46. The other end of the connecting rope 48 passes through and extends out of the inner wall of the support 2. A pull block 49 is fixedly connected to the top of the connecting rope 48. Both the first spring 42 and the second spring 47 are alloy spring steel components.
[0028] When the GNSS receiver is in operation, manually turn on fan 3. Fan 3 will rotate to draw in outside air, filter it through filter 44, and then blow it onto the surface of the receiver to dissipate heat from the receiver.
[0029] When the filter screen 44 needs to be cleaned, pull the two limit brackets 43 away from the support 2, pull the two abutment brackets 41 so that the ends of the abutment brackets 41 are away from the ends of the GNSS receiver's legs, pull the GNSS receiver so that the GNSS receiver is away from the support 2, pull the pull block 49, and pull the two positioning blocks 46 away from each other through the connecting rope 48. At this time, pull the filter screen 44 so that the filter screen 44 is away from the support 2, and clean the disassembled filter screen 44.
[0030] After cleaning, attach the two filters 44 into the support 2 respectively, loosen the pull block 49, and the elastic force of the second spring 47 pushes the positioning block 46 into the guide rod 45, so that the filter 44 is locked in the support 2.
[0031] like Figure 4 As shown, two limiting rods 410 are fixedly connected to the bottom of the support 2, and the inner wall of the limiting frame 43 is slidably connected to the surface of the limiting rods 410.
[0032] In use, the two sets of abutment frames 41 are pulled apart to move the GNSS receiver legs to the corresponding positions on the top of the support 2. The abutment frames 41 are then loosened, and the elastic force of the first spring 42 pushes the abutment frames 41 to move and abut against the end of the receiver legs. At this time, the limiting frame 43 is pushed so that it slides into the support 2, and the end of the limiting frame 43 abuts against the end of the abutment frame 41, thereby making the GNSS receiver stably installed on the support 2. When the GNSS receiver is working, the fan 3 is manually turned on. The fan 3 rotates and draws in outside air, which is filtered through the filter screen 44 and blown onto the surface of the receiver to dissipate heat from the receiver during operation.
[0033] It should be noted that the mounting base 1, support 2 and fan 3 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the fan 3 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
