[0021] The following is for reference. Figures 1-6 A filter weighing device 10 according to an embodiment of the first aspect of the present invention is described.

[0022] like Figures 1-6 As shown, the filter weighing device 10 according to the first aspect embodiment includes: a mounting bracket 1, a weighing component 2, and a weighing module 3.

[0023] Specifically, the mounting frame 1 has a first zone 101 and a second zone 102. The weighing component 2 is mounted on the mounting frame 1 and is movable between the first zone 101 and the second zone 102. The weighing module 3 is located in the first zone 101 and is used to weigh the weight of the weighing component 2. It is understood that the mounting frame 1 has a first zone 101 and a second zone 102. The first zone 101 is used to arrange the weighing module 3 for weighing. The weighing component 2 is movable between the first zone 101 and the second zone 102. The weighing component 2 is used to support the gas turbine air filter to be tested. When the weighing component 2 is located in the first zone 101, the first channel 201 of the test device 20, the third channel 103 of the filter weighing device 10, and the second channel 301 of the air outlet device 30 are connected in sequence. When the weighing component 2 is located in the second zone 102, the weighing component 2 of the filter weighing device 10 is placed on the weighing module 3, and the weighing module 3 weighs the weighing component 2. In this way, the filter is always fixed on the weighing component 2, avoiding the cumbersome operation, sealing failure, or installation error caused by repeated manual disassembly and assembly in the traditional method.

[0024] According to the present invention, the filter weighing device 10, by means of a movable weighing component 2 disposed between the first zone 101 and the second zone 102, enables the weighing of the filter without disassembly, simplifies the weighing steps, reduces the difficulty of weighing, improves the continuity and consistency of testing, and reduces the error caused by multiple manual assembly. By setting the weighing module 3, the filter can be weighed accurately, ensuring the accuracy of the test results.

[0025] In some embodiments of the present application, the filter weighing device 10 further comprises a first movement assembly 4 and a second movement assembly 5, the first movement assembly 4 is arranged on the mounting frame 1 and connected with the weighing assembly 2 to enable the weighing assembly 2 to move between the first area 101 and the second area 102, and the second movement assembly 5 is arranged on the mounting frame 1 and connected with the weighing assembly 2 to enable the weighing assembly 2 to move in the up-down direction. As shown in Figure 2 It can be understood that the first movement assembly 4 is used to drive the weighing assembly 2 to move between the first area 101 and the second area 102, that is, the first movement assembly 4 can drive the weighing assembly 2 to move from the first area 101 to the second area 102, or to move from the second area 102 to the first area 101, and the second movement assembly 5 is used to drive the weighing assembly 2 to move in the up-down direction, that is, the second movement assembly 5 can enable the weighing assembly 2 to be placed on the weighing module 3 or to be away from the weighing module 3. Therefore, the first movement assembly 4 is arranged to realize the movement of the weighing assembly 2 between the first area 101 and the second area 102, which ensures the connection accuracy and the repeatability of positioning of the channel, and improves the repeatability and reliability of the test results. The second movement assembly 5 is arranged to realize the weighing of the weighing assembly 2 on the weighing module 3, which eliminates the need for manual weighing and reduces the labor intensity.

[0026] In some embodiments of the present application, the weighing assembly 2 comprises a weighing cylinder 21 and a connecting unit 22, the weighing cylinder 21 is detachably connected with the connecting unit 22, and the weighing cylinder 21 is movably connected with the first movement assembly 4 through the connecting unit 22. As shown in Figure 2 and Figure 3 It can be understood that the weighing cylinder 21 is used to place the filter, the connecting unit 22 is used to connect the weighing cylinder 21 and the first movement assembly 4, and the weighing cylinder 21 is detachably connected with the connecting unit 22 to realize accurate weighing of the weighing cylinder 21, that is, when the weighing cylinder 21 is placed on the weighing module 3, the weighing cylinder 21 and the connecting unit 22 are separated from each other, the first movement assembly 4 drives the connecting unit 22 to move away from the weighing cylinder 21, and after the weighing is completed, the weighing cylinder 21 is connected with the connecting unit 22. Therefore, the detachable connection of the weighing cylinder 21 and the connecting unit 22 ensures the weighing accuracy of the weighing cylinder 21, and at the same time, reduces the maintenance cost and difficulty.

[0027] In some embodiments of the present application, the first movement assembly 4 comprises a first motor 41 and a first lead screw 42, the first motor 41 is in transmission connection with the first lead screw 42, the connecting unit 22 comprises a connecting seat 221 and a connecting plate 222, the connecting seat 221 is in transmission connection with the first lead screw 42, the connecting plate 222 is rotatably connected with the connecting seat 221, the weighing cylinder 21 is formed with a connecting groove 211, and the connecting plate 222 extends into the connecting groove 211. As shown in Figures 2-4As shown, it can be understood that by setting the first motor 41 to provide power for the rotation of the first screw rod 42 along the connecting unit 22, the first screw rod 42 is set to convert the rotary motion of the first motor 41 into linear motion, the connecting seat 221 is in transmission connection with the first screw rod 42, so that the first screw rod 42 rotates to make the connecting seat 221 move along the axis direction of the first screw rod 42, the connecting plate 222 and the connecting groove 211 are matched to realize the detachable connection between the connecting unit 22 and the weighing cylinder 21, and the connecting structure of the connecting plate 222 and the connecting groove 211 is simple, the failure rate is low, and maintenance is facilitated.

[0028] In some embodiments of the application, the connecting plate 222 includes two, and a first elastic member 223 is arranged between the two connecting plates 222, and the first elastic member 223 always has a force to make the two connecting plates 222 close to each other. Figure 3 As shown, it can be understood that one end of each connecting plate 222 is hinged to the connecting seat 221, the other end of each connecting plate 222 can pass through the connecting groove 211 of the weighing cylinder 21, the first elastic member 223 is connected between the two connecting plates 222 and always exerts an inward force on the two connecting plates 222, so that even if the connecting plate 222 has a tendency to open outward, the first elastic member 223 can pull it back to maintain the clamping state, thereby improving the connection stability of the connecting unit 22 and the weighing cylinder 21, avoiding loosening and falling off, and reducing the disassembly difficulty of the connecting unit 22 and the weighing cylinder 21.

[0029] In some embodiments of the application, the weighing module 3 includes a weighing seat 31, a scale body 32 and a guide member 33, as shown in Figures 2-4 As shown, the scale body 32 and the guide member 33 are arranged on the weighing seat 31, the scale body 32 is used for weighing the weight of the weighing cylinder 21, and the guide member 33 is used for driving the two connecting plates 222 to move away from each other. It can be understood that the weighing seat is arranged on the mounting frame 1, the scale body 32 is arranged on the weighing seat, the scale body 32 is used for measuring the total weight of the weighing cylinder 21 and the filter arranged on the weighing cylinder 21 in real time and accurately, and the guide member 33 is arranged on the weighing seat 31 and arranged adjacent to the scale body 32. When the weighing cylinder 21 descends and approaches the weighing module 3, the guide member 33 contacts the two connecting plates 222 and drives the two connecting plates 222 to rotate in the direction away from each other, so that the two connecting plates 222 are withdrawn from the connecting groove 211 of the weighing cylinder 21, and the weighing cylinder 21 falls on the scale body 32 to be weighed. Thus, automatic weighing can be realized without manual intervention, and the weighing cylinder 21 can avoid impact caused by sudden release under the guidance of the guide member 33, which protects the scale body 32 and the weighing cylinder 21 and the filter.

[0030] In some possible embodiments, the scale body 32 is electrically connected with a control module, the control module receives data information of the scale body 32 while sending a signal to the scale body 32, and the data information is summarized and sent to a display end of a user.

[0031] In some embodiments of the present application, as shown in Figures 2-4 The guide 33 extends in the up-down direction, and the cross-sectional area of the guide 33 gradually increases in the up-down direction. It can be understood that the guide 33 is vertically installed on the weighing seat 31, the guide 33 is conical, and the cross-sectional area of the guide 33 gradually increases in the up-down direction, so that the connecting plates 222 are uniformly and continuously stressed, and sudden bouncing or jamming is avoided, and mechanical impact and vibration are reduced.

[0032] Specifically, the interiors of the two connecting plates 222 first contact the region with a smaller diameter on the upper part of the guide 33, and as the weighing cylinder 21 continues to descend, the connecting plates 222 slide along the inclined side wall of the guide 33, the guide 33 causes the two connecting plates 222 to move away from each other, and when the weighing cylinder 21 descends to the bottom, the connecting plates 222 are fully expanded and exit from the connecting grooves 211 of the weighing cylinder 21, and the weighing cylinder 21 freely falls on the scale body 32, and precise weighing is achieved; after the weighing is completed, the connecting assembly moves upward, the first elastic member 223 drives the two connecting plates 222 to move close to each other, the connecting plates 222 extend into the connecting grooves 211 of the weighing cylinder 21, and as the connecting assembly moves upward, the first elastic member 223 continuously drives the two connecting plates 222 to move close to each other while the connecting plates 222 slide along the inclined side wall of the guide 33, and the first elastic member 223 causes the two connecting plates 222 to move close to each other.

It can be understood that by arranging the first motor 41 and the first lead screw 42, the motion accuracy is ensured, the repeatability of the first motion assembly 4 is achieved, the first guide rail frame 43 guides the motion of the weighing cylinder 21, and the accurate and stable operation of the weighing cylinder 21 between the first area 101 and the second area 102 is ensured.

[0034] In some embodiments of the present application, as shown in Figure 4As shown, the second motion component 5 includes a second motor 51 and a second lead screw 52. The second lead screw 52 extends in the vertical direction, and the second motor 51 is driven by the second lead screw 52. The first guide rail frame 43 is driven by the second lead screw 52 to allow the weighing cylinder 21 to slide in the vertical direction. It can be understood that by setting the second motor 51 and the second lead screw 52, ​​motion accuracy is ensured, and the repeatability of the second motion component 5 is achieved. The second guide rail frame guides the movement of the weighing cylinder 21, ensuring that the weighing cylinder 21 can run accurately and smoothly in the vertical direction.

[0035] Furthermore, with the cooperation of the first motion component 4 and the second motion component 5, the weighing cylinder 21 can achieve horizontal and vertical movements, both of which are driven by lead screws, ensuring motion accuracy and making the movement of the weighing cylinder 21 repeatable, thereby enhancing the load-bearing capacity and operational stability of the filter weighing device 10.
