Description

Technical Field

[0001] This application belongs to the technical field of rain testing for charging cabinets, and specifically relates to a rain testing machine for charging cabinets. Background Technology

[0002] With strong government support for new energy, the number of new energy vehicles is increasing, leading to the emergence of charging cabinets. Charging cabinets offer advantages such as high charging power and the ability to charge multiple new energy vehicles simultaneously. Since charging cabinets are typically installed outdoors, rain tests are necessary during the manufacturing process to ensure their safety.

[0003] Currently, when conducting rain tests on charging cabinets, workers typically hold a showerhead and aim it at the cabinet to spray water onto its exterior. However, due to the cabinet's height, a blind spot exists at the top, affecting the accuracy of the test results, increasing labor costs, and reducing efficiency. Utility Model Content

[0004] This application provides a rain test machine for charging cabinets to improve the accuracy of rain test results and reduce the labor cost of conducting rain tests.

[0005] The technical solution adopted in this application is as follows:

[0006] A rain test chamber for charging cabinets, comprising:

[0007] A support frame, the support frame having an internal accommodating space for placing a charging cabinet;

[0008] A rotating arm having a top spray mounting area and a side spray mounting area located below the top spray mounting area;

[0009] A spray assembly, comprising a plurality of spray heads, some of which are installed in the top spray mounting area and the remaining spray heads are installed in the side spray mounting area;

[0010] A drive assembly is provided to drive the rotating arm to rotate, so that the rotating arm drives a plurality of spray heads to rotate circumferentially around the charging cabinet placed in the accommodating space.

[0011] By adopting the above technical solution, when conducting a rain test on the charging cabinet using the rain test machine described in this application, the charging cabinet is placed in the accommodating space, and then an external water supply device is connected to multiple spray heads. This allows the external water supply device to deliver water to the spray heads, so that the water is sprayed onto the charging cabinet through the spray heads. Since some spray heads are installed in the top spray mounting area and the remaining spray heads are installed in the side spray mounting area, and the side spray mounting area is located below the top spray mounting area, the spray heads installed in the top spray mounting area spray water onto the top of the charging cabinet, and the spray heads installed in the side spray mounting area spray water onto the sides of the charging cabinet. The system performs rain spraying, and after the drive assembly is activated, it drives the rotating arm to rotate, causing multiple spray heads to rotate around the charging cabinet placed in the accommodating space. This enables multi-angle rain testing of the charging cabinet, thereby improving the accuracy of the test results. Furthermore, no personnel are required to participate in the rain testing, reducing labor costs and labor intensity. The multiple spray heads can also rotate circumferentially around the charging cabinet, significantly improving the efficiency of the rain testing.

[0012] Optionally, the rotating arm includes a crossbeam and a vertical beam extending downward from the crossbeam, the crossbeam forming the top spray mounting area and the vertical beam forming the side spray mounting area.

[0013] By adopting the above technical solution, since the crossbeam forms the top spray installation area and the vertical beam forms the side spray installation area, the spray head installed in the top spray installation area sprays water from top to bottom, thereby reducing the demand for water pressure and thus reducing the power requirements of the external water supply equipment; in addition, the height of the spray head installed in the top spray installation area is raised, so that the rain test machine in this application can be applied to various models of charging cabinets, thereby increasing the flexibility of the rain test machine.

[0014] Optionally, the top of the support frame has a support plate, the drive assembly includes a rotating seat rotatably connected to the support plate and a drive member for driving the rotating seat to rotate, and the crossbeam is connected to the rotating seat.

[0015] By adopting the above technical solution, when conducting a rain test on the charging cabinet, the drive unit is activated, which drives the rotating seat, causing the rotating seat to rotate relative to the support plate. Simultaneously, since the crossbeam is connected to the rotating seat, the rotation of the rotating seat drives the rotating arm to rotate, thereby achieving circumferential water spraying on the charging cabinet. Furthermore, because the crossbeam is connected to the rotating seat, the installation position of the rotating arm is located at the top, which can avoid the charging cabinet that will be placed in the placement space, thereby reducing the difficulty of placing the charging cabinet in the placement space and further improving the efficiency of conducting a rain test on the charging cabinet.

[0016] Optionally, the rotating seat includes a rotating ring rotatably connected to the support plate and a connecting sleeve sleeved outside the crossbeam. The crossbeam can move relative to the connecting sleeve along its own length so that the distance between the vertical beam and the connecting sleeve can be adjusted.

[0017] By adopting the above technical solution, since the crossbeam can move relative to the rotating sleeve along its own length, the position of the vertical beam can be adjusted according to the model of the charging cabinet to keep the vertical beam and the charging cabinet at a more suitable distance. This avoids wasting water resources due to the distance between the sprinkler head on the vertical beam and the charging cabinet, thereby achieving the effect of saving water resources. Furthermore, it reduces the requirements for the placement of the charging cabinet, thereby further improving the efficiency of rain testing on the charging cabinet.

[0018] Optionally, the connecting sleeve is provided with a locking member, which is movable relative to the connecting sleeve, so that the locking member has a locking position that abuts against or passes through the crossbeam and an unlocking position that is separated from the crossbeam.

[0019] By adopting the above technical solution, when adjusting the distance between the vertical beam and the connecting sleeve, the locking component is operated first, and then the locking component moves from the locked position to the unlocked position to separate the locking component from the crossbeam. Then, the vertical beam is pulled or pushed, so that the vertical beam drives the crossbeam to move, and the crossbeam and the connecting sleeve move relative to each other to adjust the distance between the vertical beam and the connecting sleeve. After the position of the vertical beam is adjusted, the locking component is operated to move from the unlocked position to the locked position. The locking component is pressed against or inserted into the crossbeam to lock the crossbeam. This avoids the situation where the rotating arm slides relative to the connecting sleeve under the action of centrifugal force when the connecting sleeve drives the rotating arm to rotate, thereby increasing the stability of the rotating arm and improving the safety of the rain test machine.

[0020] Optionally, the connecting sleeve is rotatably connected to a roller, at least a portion of which extends into the interior of the connecting sleeve to abut against the outer circumferential surface of the crossbeam.

[0021] By adopting the above technical solution, since at least a portion of the rolling wheel extends into the interior of the connecting sleeve and abuts against the outer circumferential surface of the crossbeam, the crossbeam contacts the inner wall of the connecting sleeve through the rolling wheel. This allows the rolling wheel to roll relative to the crossbeam when the rotating arm is adjusted, thereby reducing the friction between the crossbeam and the connecting sleeve. This facilitates the adjustment of the rotating arm and also reduces the force required to be applied to the vertical beam when adjusting the rotating arm, thus greatly reducing the workload of the workers.

[0022] Optionally, the rain test machine further includes a water supply pipe, which is located on the rotating arm and connected to a plurality of spray heads. The support plate is provided with a rotary joint connected to the water supply pipe, and the rotary joint is coaxially arranged with the rotating ring.

[0023] By adopting the above technical solution, the number of pipes is reduced due to the connection between the water supply pipe and multiple spray heads, thereby reducing the production cost of the rain test machine. At the same time, it also facilitates the connection between the spray heads and external water supply equipment. Furthermore, the connection between the rotary joint and the water supply pipe avoids the water supply pipe from getting tangled when the rotating arm rotates, thus ensuring the service life of the water supply pipe and the spray volume of the spray heads, thereby ensuring the test effect on the charging cabinet.

[0024] Optionally, the support plate is provided with a mounting sleeve, and the side of the mounting sleeve is provided with a mounting notch, through which the rotary joint is mounted to the mounting sleeve.

[0025] By adopting the above technical solution, the installation difficulty of the rotary joint is reduced because it is installed on the mounting sleeve through the mounting notch. At the same time, the mounting sleeve is placed on the mounting plate, which enables the mounting sleeve to support the rotary joint, thereby increasing the stability of the rotary joint and further avoiding the occurrence of water supply pipe entanglement.

[0026] Optionally, the connecting sleeve has connecting pieces that are fixedly connected to the rotating ring extending upward on both opposite sides, and the water supply pipe is located between the two connecting pieces.

[0027] By adopting the above technical solution, since the water supply pipe is located between the two connecting plates, on the one hand, the connecting plates can protect the water supply pipe to ensure its service life, and on the other hand, the water supply pipe can pass through the rotating ring to further avoid the water supply pipe from getting tangled.

[0028] Optionally, the rotating arm is provided with a fixed base, the fixed base including a fixed block, a pressing block and fasteners connecting the pressing block and the fixed block, each spray head including a spray pipe and a nozzle, the spray pipe being located between the fixed block and the pressing block to press and fix the spray pipe.

[0029] By adopting the above technical solution, the spray pipe is fixed by the compression of the fixing block and the squeezing block, which allows the spray direction of the nozzle to be adjusted so that more water can be sprayed onto the charging cabinet. When adjusting the spray direction of the nozzle, the fastener is operated so that the squeezing block and the fixing block release the compression of the spray pipe. Then the spray pipe is rotated so that the spray pipe drives the nozzle to rotate, thereby adjusting the spray angle of the nozzle.

[0030] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0031] 1. The rain test machine of this application includes a support frame, a rotating arm, a spray assembly, and a drive assembly. The support frame has an internal space for accommodating a charging cabinet. The rotating arm has a top spray mounting area and a side spray mounting area located below the top spray mounting area. The spray assembly includes multiple spray heads, some of which are installed in the top spray mounting area and the remaining spray heads are installed in the side spray mounting area. The drive assembly is used to drive the rotating arm to rotate, so that the rotating arm drives the multiple spray heads to rotate around the charging cabinet placed in the accommodating space. This allows the charging cabinet to be rain tested without the need for personnel intervention, thereby reducing the input cost of personnel and lowering the labor cost of rain testing the charging cabinet. Furthermore, the multiple spray heads can rotate around the charging cabinet, which greatly improves the efficiency of rain testing the charging cabinet.

[0032] 2. The rotating arm in this application includes a crossbeam and a vertical beam extending downward from the crossbeam. The crossbeam forms a top spray mounting area, and the vertical beam forms a side spray mounting area. This allows the spray heads installed in the top spray mounting area to spray from top to bottom, reducing the water pressure requirement and thus reducing the power requirement for external water supply equipment. Furthermore, by raising the height of the spray heads installed in the top spray mounting area, the rain test machine in this application can be applied to various models of charging cabinets, thereby increasing the flexibility of the rain test machine.

[0033] 3. The support frame in this application has a support plate at the top. The drive assembly includes a rotating seat rotatably connected to the support plate and a drive component for driving the rotating seat to rotate. A crossbeam is connected to the rotating seat. When the charging cabinet is subjected to a rain test, the drive component is activated, and the drive component drives the rotating seat, thereby causing the rotating seat to rotate relative to the support plate. At the same time, since the crossbeam is connected to the rotating seat, the rotating seat rotates, causing the rotating arm to rotate, so as to spray water around the charging cabinet in the circumference. Furthermore, since the crossbeam is connected to the rotating seat, the installation position of the rotating arm is located at the top, so as to avoid the charging cabinet that will be placed in the placement space, thereby reducing the difficulty of placing the charging cabinet in the placement space and further improving the efficiency of the rain test on the charging cabinet.

[0049] Reference Figures 1 to 7 A rain test machine for charging cabinets is disclosed, which includes a support frame 1, a rotating arm 2, a spray assembly, and a drive assembly 4. The support frame 1 has an internal accommodating space for placing the charging cabinet. The rotating arm 2 has a top spray mounting area and a side spray mounting area located below the top spray mounting area. The spray assembly includes multiple spray heads 3, some of which are installed in the top spray mounting area and the remaining spray heads 3 are installed in the side spray mounting area. The drive assembly 4 is used to drive the rotating arm 2 to rotate, so that the rotating arm 2 drives the multiple spray heads 3 to rotate around the charging cabinet placed in the accommodating space.

[0050] When conducting a rain test on the charging cabinet using the rain test machine described in this application, the charging cabinet is placed in the accommodating space, and then an external water supply device is connected to multiple spray heads 3 so that the external water supply device can deliver water to the spray heads 3, and the water is sprayed onto the charging cabinet through the spray heads 3. Since some spray heads 3 are installed in the top spray mounting area and the remaining spray heads 3 are installed in the side spray mounting area, and the side spray mounting area is located below the top spray mounting area, the spray heads 3 installed in the top spray mounting area spray water onto the top of the charging cabinet, and the spray heads 3 installed in the side spray mounting area spray water onto the sides of the charging cabinet. After the drive component 4 is started, the drive component 4 can drive the rotating arm 2 to rotate, so that the rotating arm 2 drives multiple spray heads 3 to rotate around the charging cabinet placed in the accommodating space, thereby realizing a multi-angle rain test on the charging cabinet, and thus improving the accuracy of the test results when conducting a rain test on the charging cabinet.

[0051] Meanwhile, no staff are required to participate in the rain test of the charging cabinet, thereby reducing the input cost of staff and the labor cost of the rain test of the charging cabinet. In addition, multiple spray heads 3 can rotate around the circumference of the charging cabinet, which greatly improves the efficiency of the rain test of the charging cabinet.

[0052] This application does not specifically limit the structure of the support frame 1; preferably, refer to... Figure 1 , Figure 2 and Figure 3 The support frame 1 includes a top frame 11 and columns 12 fixedly connected to the corners of the top frame 11. The columns 12 are located at the bottom of the top frame 11 so that the columns 12 support the top frame 11, thereby increasing the stability of the support frame 1.

[0053] Furthermore, refer to Figure 3 Each column 12 is equipped with an adjustable support leg 121 at its bottom. The adjustable support leg 121 is fixedly connected to the corresponding column 12 by bolt pairs. When the rain test machine is installed on an uneven ground, the relative position of the adjustable support leg 121 and the column 12 can be adjusted to keep the top frame 11 level.

[0054] In other embodiments, the support frame 1 may also be a C-shaped gantry frame.

[0055] This application does not specifically limit the structure of the rotating arm 2; preferably, refer to... Figure 3 , Figure 4 and Figure 5The rotating arm 2 includes a crossbeam 21 and a vertical beam 22 extending downward from the crossbeam 21. The crossbeam 21 forms a top spray mounting area, and the vertical beam 22 forms a side spray mounting area. This allows the spray head 3 installed in the top spray mounting area to spray from top to bottom, thereby reducing the water pressure requirement and thus reducing the power requirement of the external water supply equipment. Furthermore, by raising the height of the spray head 3 installed in the top spray mounting area, the rain test machine of this application can be applied to various models of charging cabinets, thereby increasing the flexibility of the rain test machine.

[0056] Furthermore, a reinforcing plate is provided between the horizontal beam 21 and the vertical beam 22. One end of the reinforcing plate is fixedly connected to the horizontal beam 21, and the other end of the reinforcing plate is fixedly connected to the vertical beam 22 to increase the connection stability between the horizontal beam 21 and the vertical beam 22.

[0057] Furthermore, refer to Figure 2 and Figure 3 The support frame 1 has a support plate 111 on its top. The drive assembly 4 includes a rotating seat 41 rotatably connected to the support plate 111 and a drive member 42 for driving the rotating seat 41 to rotate. The crossbeam 21 is connected to the rotating seat 41.

[0058] Specifically, during the rain test of the charging cabinet, the drive unit 42 is activated, which drives the rotating seat 41, causing the rotating seat 41 to rotate relative to the support plate 111. Simultaneously, since the crossbeam 21 is connected to the rotating seat 41, the rotation of the rotating seat 41 drives the rotating arm 2 to rotate, thereby spraying water around the charging cabinet in the circumference. Furthermore, since the crossbeam 21 is connected to the rotating seat 41, the installation position of the rotating arm 2 is located at the top, which can avoid the charging cabinet that will be placed in the placement space, thereby reducing the difficulty of placing the charging cabinet in the placement space and further improving the efficiency of the rain test of the charging cabinet.

[0059] Furthermore, refer to Figure 4 , Figure 5 and Figure 6 The rotating seat 41 includes a rotating ring 411 rotatably connected to the support plate 111 and a connecting sleeve 412 sleeved on the outside of the crossbeam 21. The crossbeam 21 can move relative to the connecting sleeve 412 along its own length so that the distance between the vertical beam 22 and the connecting sleeve 412 can be adjusted.

[0060] Since the crossbeam 21 can move relative to the rotating sleeve along its own length, the position of the vertical beam 22 can be adjusted according to the model of the charging cabinet, so that the vertical beam 22 and the charging cabinet are kept at a more suitable distance, so as to avoid the waste of water resources due to the distance between the spray head 3 on the vertical beam 22 and the charging cabinet. This achieves the effect of saving water resources and reduces the requirements for the placement of the charging cabinet, thereby further improving the efficiency of rain testing on the charging cabinet.

[0061] This application does not specifically limit the rotational connection method between the rotating ring 411 and the support plate 111. The support plate 111 can be provided with a central hole through which the rotating ring 411 passes, and the top of the rotating ring 411 is provided with an edge that can cooperate with the stop of the support plate 111. The edge is located at the top of the support plate 111 so that the edge cooperates with the stop of the support plate 111 to support the rotating ring 411, thereby realizing the rotational connection between the rotating ring 411 and the support plate 111. Of course, the rotating ring 411 can also be rotated to connect with the support plate 111 in other ways.

[0062] This application does not specifically limit the structure of the drive component 42. Preferably, the drive component 42 is a servo motor, and the output shaft of the servo motor is provided with a gear. The outer peripheral surface of the rotating ring 411 has teeth that can mesh with the gear, so that the output shaft of the servo motor drives the rotating ring 411 to rotate through the gear, thereby driving the rotation of the rotating arm 2. In other embodiments, the drive component 42 can also be a pneumatic motor or a hydraulic transmission structure.

[0063] Furthermore, the connecting sleeve 412 is provided with a locking member, which can move relative to the connecting sleeve 412 so that the locking member has a locking position that abuts against or passes through the crossbeam 21 and an unlocking position that is separated from the crossbeam 21.

[0064] When adjusting the distance between the vertical beam 22 and the connecting sleeve 412, first operate the locking member, then move the locking member from the locked position to the unlocked position to separate the locking member from the cross beam 21. Then pull or push the vertical beam 22, so that the vertical beam 22 drives the cross beam 21 to move. The cross beam 21 and the connecting sleeve 412 move relative to each other to adjust the distance between the vertical beam 22 and the connecting sleeve 412. After the position of the vertical beam 22 is adjusted, operate the locking member to move the locking member from the unlocked position to the locked position. The locking member is pressed against or inserted into the cross beam 21 to lock the cross beam 21. This avoids the situation where the rotating arm 2 slides relative to the connecting sleeve 412 under the action of centrifugal force when the connecting sleeve 412 drives the rotating arm 2 to rotate, thereby increasing the stability of the rotating arm 2 and improving the safety of the rain test machine.

[0065] This application does not specifically limit the structure of the locking member. Preferably, the locking member is a locking bolt threaded to the connecting sleeve 412, and the end of the locking bolt away from the bolt head can extend into the interior of the connecting sleeve 412 and abut against the outer circumferential surface of the crossbeam 21 to achieve stepless adjustment of the rotating arm 2, allowing the rotating arm 2 to stop at any position. In other embodiments, the locking member can also be a locking rod passing through the connecting sleeve 412, and the crossbeam 21 is provided with multiple holes for the locking rod to pass through, so that the locking rod can extend into the crossbeam 21 to lock the crossbeam 21.

[0066] Furthermore, refer to Figure 5 and Figure 6 The connecting sleeve 412 is rotatably connected to a rolling wheel 413. At least a portion of the rolling wheel 413 extends into the interior of the connecting sleeve 412 to abut against the outer circumferential surface of the crossbeam 21. This allows the crossbeam 21 to contact the inner wall of the connecting sleeve 412 via the rolling wheel 413. When adjusting the rotating arm 2, the rolling wheel 413 can roll relative to the crossbeam 21, thereby reducing the friction between the crossbeam 21 and the connecting sleeve 412. This facilitates the adjustment of the rotating arm 2 and also reduces the force required to be applied to the vertical beam 22 when adjusting the rotating arm 2, thus greatly reducing the workload of the workers.

[0067] Preferably, at least two sets of rollers 413 are provided. One set of rollers 413 is located at one end of the connecting sleeve 412, and the other set of rollers 413 is located at the other end of the connecting sleeve 412. Each set of rollers 413 includes multiple rollers 413, which are arranged sequentially along the circumference of the crossbeam 21 to ensure the balance of the crossbeam 21, avoid jamming between the crossbeam 21 and the connecting sleeve 412, and further ensure the effect of facilitating the adjustment of the rotating arm 2.

[0068] Furthermore, refer to Figure 5 , Figure 6 and Figure 7 The rain test machine also includes a water supply pipe 5, which is located on the rotating arm 2 and connected to multiple spray heads 3. The support plate 111 is provided with a rotary joint 51 connected to the water supply pipe 5, and the rotary joint 51 is coaxially arranged with the rotating ring 411.

[0069] Because the water supply pipe 5 is connected to multiple spray heads 3, the number of pipes is reduced, thereby lowering the production cost of the rain test machine. At the same time, it also facilitates the connection of the spray heads 3 to external water supply equipment. Furthermore, the rotary joint 51 is connected to the water supply pipe 5, thereby preventing the water supply pipe 5 from getting tangled when the rotating arm 2 rotates, ensuring the service life of the water supply pipe 5 and the spray volume of the spray heads 3, thus ensuring the test effect on the charging cabinet.

[0070] Preferably, the interior of the crossbeam 21 and the vertical beam 22 is hollow, and the water supply pipe 5 passes through the interior of the crossbeam 21 and the vertical beam 22. The crossbeam 21 and the vertical beam 22 have connecting ports 211 at the positions where the spray head 3 is located, so that the pipeline connecting the water supply pipe 5 and the spray head 3 can pass through the connecting ports 211 to ensure the connection between the water supply pipe 5 and the spray head 3. At the same time, the crossbeam 21 and the vertical beam 22 can protect the water supply pipe 5 to extend the service life of the water supply pipe 5.

[0071] Furthermore, refer to Figure 2 , Figure 3 and Figure 7 The support plate 111 is provided with an installation sleeve 112. The side of the installation sleeve 112 is provided with an installation notch. The rotary joint 51 is installed on the installation sleeve 112 through the installation notch, thereby reducing the difficulty of installing the rotary joint 51. At the same time, the installation sleeve 112 is located on the mounting plate, so that the installation sleeve 112 can support the rotary joint 51, thereby increasing the stability of the rotary joint 51 and further preventing the water supply pipe 5 from getting tangled.

[0072] Preferably, the mounting sleeve 112 is located on the top of the support plate 111, which on the one hand allows the mounting sleeve 112 to avoid the connecting sleeve 412, and on the other hand raises the position of the rotary joint 51 so that the rotary joint 51 avoids the connecting sleeve 412.

[0073] Furthermore, refer to Figure 5 and Figure 6 The connecting sleeve 412 has connecting pieces 414 that are fixedly connected to the rotating ring 411 on both sides extending upward. The water supply pipe 5 is located between the two connecting pieces 414. On the one hand, the connecting pieces 414 can protect the water supply pipe 5 to ensure the service life of the water supply pipe 5. On the other hand, the water supply pipe 5 can pass through the rotating ring 411 to further prevent the water supply pipe 5 from getting tangled.

[0074] In other embodiments, the rotating arm 2 may only include the vertical beam 22, and the drive assembly 4 includes an annular track on the top of the support frame 1 and a trolley that travels on the annular track. The vertical beam 22 is connected to the trolley to enable the rotating arm 2 to rotate circumferentially around the charging cabinet placed in the accommodating space.

[0075] In a preferred embodiment, refer to Figure 4 and Figure 5 Each spray head 3 includes a spray pipe 31 and a nozzle 32. The rotating arm 2 is provided with a fixed base, which includes a fixed block 23, a pressing block 24 and fasteners connecting the pressing block 24 and the fixed block 23. Each spray head 3 includes a spray pipe 31 and a nozzle 32. The spray pipe 31 is located between the fixed block 23 and the pressing block 24 to press and fix the spray pipe 31.

[0076] Since the spray pipe 31 is fixed by the compression of the fixing block 23 and the squeezing block 24, the spray direction of the nozzle 32 can be adjusted so that more water is sprayed onto the charging cabinet, thereby saving water and reducing the cost of rain testing on the charging cabinet. When adjusting the spray direction of the nozzle 32, the fasteners are operated to release the squeezing block 24 and the fixing block 23 from the spray pipe 31. Then the spray pipe 31 is rotated so that the spray pipe 31 drives the nozzle 32 to rotate, thereby adjusting the spray angle of the nozzle 32.

[0077] This application does not specify the structure of the fastener, which can be bolts, screws, or other structures.
