DETAILED DESCRIPTION

[0024] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] With reference to Figures 1-3 An embodiment provided by the present application is a water conservancy irrigation variable frequency control device, which comprises a control cabinet body 1 and a moisture-proof assembly. The control cabinet body 1 is usually made of a solid and durable metal material, such as stainless steel or cold-rolled steel plate, has good protection performance, can effectively protect the internal electrical elements from the influence of the external environment, and is fixedly connected with a fixed plate 2 inside. The fixed plate 2 plays a role in supporting and fixing other components, is generally processed from a metal plate with appropriate thickness, ensures that it has sufficient strength and stability, and is fixedly connected with four L-shaped plates 3 on the outside. The L-shaped plates 3 can be made of the same material as the fixed plate 2, and their shape design can provide stable support and limiting for the mounting plate 6. The outside of the fixed plate 2 is provided with a mounting plate 6, which is usually a plate made of insulating material, such as a phenolic resin plate or a glass fiber reinforced plastic plate, and is used for mounting various electrical elements. The outside of the fixed plate 2 is provided with a dismounting assembly, which is used for quickly separating the mounting plate 6 from the fixed plate 2. The dismounting assembly comprises four springs 4, which are arranged inside the fixed plate 2. The springs 4 are usually metal springs with a certain elastic coefficient, which can provide stable elastic force during compression and expansion. One end of the spring 4 is fixedly connected with a movable plate 5, which can be made of plastic or metal material. The sliding of the movable plate 5 in the limiting groove 8 can drive the movement of the clamping block 9. The outside of the movable plate 5 is fixedly connected with the clamping block 9, which is generally made of metal material and has a shape and size design that can tightly fit with the mounting plate 6 to fix the mounting plate 6. The inside of the mounting plate 6 is provided with four mounting holes 7, which are matched in size and shape with the L-shaped plates 3, so that the mounting plate 6 can be installed on the L-shaped plates 3 through the mounting holes 7. The inside of the fixed plate 2 is provided with four limiting grooves 8, which provide a track for the movement of the movable plate 5 to ensure the stability of its movement. The outside of the L-shaped plate 3 is slidably connected with the inside of the mounting hole 7, the outside of the movable plate 5 is slidably connected with the inside of the limiting groove 8, the other end of the spring 4 is fixedly connected with the inside of the limiting groove 8, and the outside of the clamping block 9 is tightly fitted with the outside of the mounting plate 6.

[0026] Specifically, when various types of electrical components installed on the surface of the mounting plate 6 fail due to long-term operation, external environmental interference or other factors, and need to be repaired, we can follow the following steps. First, the clamping block 9 can be pushed. The clamping block 9 is a key component that closely fits the outside of the mounting plate 6 and is fixed to the outside of the movable plate 5. When an external force is applied to push the clamping block 9, the clamping block 9 will move the movable plate 5 upwards. The movable plate 5 slides in the limiting groove 8 inside the fixed plate 2. This sliding method ensures that the movable plate 5 maintains a stable trajectory during movement and does not deviate or shift. The movement of the movable plate 5 is achieved by overcoming the elastic force of the spring 4, which is fixed at one end to the movable plate 5 and at the other end to the inside of the limiting groove 8. It has a certain elastic coefficient and can provide corresponding elastic feedback when compressed or stretched. Then, after pushing the clamping block 9 to move the movable plate 5 upwards to the appropriate position, the mounting plate 6 can be moved outside the control cabinet body 1. At this time, the mounting plate 6 will slide along the outside of the L-shaped plate 3. Because the outside of the L-shaped plate 3 is in a sliding connection with the inside of the mounting hole 7 inside the mounting plate 6, this connection method ensures the stability of the mounting plate 6 in the normal installation state and allows it to slide relative to the mounting hole 7 when it needs to be removed. Then, after lifting the mounting plate 6 and moving it a certain height, continue to move it outside the control cabinet body 1. The reason for this horizontal and then vertical movement is that the inside space of the mounting hole 7 can allow the L-shaped plate 3 and the clamping block 9 to pass smoothly after such operation. In this way, the mounting plate 6 and the various types of electrical components on its surface can be completely removed and moved out of the control cabinet body 1. The advantage of this is that after removing the electrical components, maintenance personnel have more spacious operating space. Compared to repairing faulty electrical components directly inside the control cabinet body 1, this method avoids the inconvenience of operating in a narrow space, such as tools not being able to be used, vision being blocked, and other issues. Therefore, it is more convenient.

[0027] Referring to Figures 3-5The moisture-proof assembly comprises a drawer 15 arranged at the inner side of the control cabinet cabinet body 1, the drawer 15 is usually made of plastic or metal material and has certain strength and durability, the inner side of the control cabinet cabinet body 1 is provided with a receiving groove 10, the size and shape of the receiving groove 10 are matched with the drawer 15, so that the drawer 15 can smoothly slide in the receiving groove 10, the outer side of the drawer 15 is in sliding connection with the inner side of the receiving groove 10, the inner side of the drawer 15 is placed with a plurality of moisture absorbents 18, the moisture absorbents 18 can be selected from silica gel desiccant or activated carbon and other materials with good moisture absorption performance, which can effectively absorb the moisture in the control cabinet cabinet body 1, the outer side of the drawer 15 is fixedly connected with a handle 17, the handle 17 is generally made of plastic or metal material, which is convenient for the user to pull the drawer 15, two clamping grooves 16 are arranged at the outer sides of the drawer 15, the size and shape of the clamping grooves 16 are matched with the clamping balls 13, which are used to fix the drawer 15, two cavities 11 are arranged in the control cabinet cabinet body 1, the cavities 11 provide installation space for the spring two 12 and the clamping ball 13, two spring two 12 are arranged in the control cabinet cabinet body 1, the spring two 12 is usually made of metal spring and has certain elasticity and durability, one end of the spring two 12 is fixedly connected with the inner side of the cavity 11, the other end of the spring two 12 is fixedly connected with the clamping ball 13, the clamping ball 13 is generally made of metal material and can be clamped into the clamping groove 16 under the elastic force of the spring two 12 to fix the drawer 15, the outer side of the clamping ball 13 is in abutment with the inner side of the clamping groove 16, the inner wall of the cavity 11 is provided with a through hole 14, the size and shape of the through hole 14 are designed to allow the clamping ball 13 to smoothly pass through and be clamped into the clamping groove 16 under the pushing of the spring two 12.

[0028] Specifically, when the inside of the control cabinet body 1 needs to be treated for moisture-proof, the handle 17 can be pulled. The handle 17 is a component fixedly connected to the outside of the drawer 15, generally designed in a shape convenient for a human hand to hold, and has a certain strength, facilitating the user to exert force. By pulling the handle 17, the drawer 15 can be smoothly pulled out from the inside of the storage groove 10 formed on the inside of the control cabinet body 1. The size of the storage groove 10 is matched with the drawer 15, which can ensure smooth sliding and accurate position of the drawer 15 during pulling out and pushing in. After pulling out the drawer 15, a plurality of moisture-proof agents 18 can be placed inside the drawer 15. The moisture-proof agents 18 can be selected from materials with good moisture absorption performance, such as silica gel desiccant and activated carbon. These materials can effectively absorb moisture in the surrounding environment, thereby achieving the purpose of moisture-proof. Then, the drawer 15 is pushed into the inside of the storage groove 10. During this process, since the control cabinet body 1 is internally provided with two springs 12, one end of the spring 12 is fixedly connected to the inside of the cavity 11 formed in the control cabinet body 1, and the other end is fixedly connected to the clamping bead 13. When the drawer 15 is pushed into the inside of the storage groove 10, the clamping bead 13 will pass through the through hole 14 formed in the inner wall of the cavity 11 and be accurately clamped into the clamping groove 16 formed on the two sides of the drawer 15. In this way, the position of the drawer 15 can be stabilized, ensuring that the drawer 15 will not be displaced during normal use due to slight external vibrations or other factors. The moisture-proof agents 18 placed in the inside of the drawer 15 can continuously absorb the moisture in the inside of the control cabinet body 1, thereby effectively playing a moisture-proof role and protecting the electrical components in the inside of the control cabinet body 1 from moisture erosion, prolonging the service life thereof.

[0029] Working principle: when the electrical components on the surface of the mounting plate 6 need to be repaired, the clamping block 9 is pushed to drive the movable plate 5 to move upwards, and then the mounting plate 6 is moved to the outside of the control cabinet body 1. After lifting the mounting plate 6 to move upwards and then continuing to move to the outside of the control cabinet body 1, the inside of the mounting hole 7 is just large enough for the L-shaped plate 3 and the clamping block 9 to pass through. In this way, the mounting plate 6 together with the electrical components on the surface thereof can be removed from the inside of the control cabinet body 1, and then the electrical components can be repaired, which can have a more spacious operating space and is more convenient than directly repairing in the inside of the control cabinet body 1.

[0030] In addition, the handle 17 can be pulled to pull the drawer 15 out of the inside of the storage groove 10, a plurality of moisture-proof agents 18 are placed in the inside of the drawer 15, and then the drawer 15 is pushed into the inside of the storage groove 10. The clamping bead 13 is pushed by the spring 12 to pass through the through hole 14 and be clamped into the clamping groove 16, so that the position of the drawer 15 can be stabilized. The moisture-proof agents 18 in the inside of the drawer 15 can absorb the moisture in the inside of the control cabinet body 1, thereby playing a moisture-proof role.

[0031] It should be pointed out finally that the above only for the preferred embodiments of the present application and is not intended to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of some of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included within the scope of the present application.
