TECHNICAL FIELD

[0001] The utility model belongs to the technical field of control device, especially related to a switch cabinet control device with detachable dustproof structure. BACKGROUND

[0002] The switch cabinet control device is a kind of equipment used in power system, mainly used to control and operate electrical switch device, such as circuit breaker and disconnecting switch. It usually includes control panel, protection device, indicating instrument and communication interface module, and can realize remote or on-site control of switch device. Through control device, operating personnel can monitor the running state of electrical equipment in real time, and handle fault in time, so as to ensure the safe and stable operation of power system. Although the existing switch cabinet control device has many functions, it still has shortcomings, such as there are many dust impurities in the environment of switch cabinet work, which may enter the control device through the gap on the control panel and cause short circuit or poor contact of internal components. The conventional solution is to install dustproof structure outside the control panel to prevent dust from entering, but this method has the disadvantage that although the dustproof structure can prevent dust from entering the control device, it is fixed on the outside of the control panel, so it is not convenient to disassemble and maintain. Therefore, a new structure is proposed to solve the above problems. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a switch cabinet control device with detachable dustproof structure.

[0006] The mounting frame is provided with a dustproof plate, an operation window is formed in the front of the dustproof plate, a movable plate is arranged on the outer side of the operation window, a group of pull strips are arranged on the left and right sides of the front of the movable plate, a dust strip two is bonded below the operation window, and clamping holes are formed in the left and right sides of the lower side of the front of the dustproof plate.

[0007] As a preferred implementation, the front of the chassis shell inside the mounting frame is provided with a control panel, a dustproof strip one is glued above the control panel, and the thickness of the dustproof strip one is greater than the distance length from the disassembly slot one to the front of the chassis shell.

[0008] As a preferred implementation, the dustproof strip one is made of sponge, the left and right sides of the dustproof strip one are respectively glued with the left and right inner sides of the mounting frame, the width of the disassembly slot one matches the thickness of the dustproof plate, and the thickness of the disassembly slot one is the same as the thickness of the disassembly slot two. Since the sponge has good shrinkage and resilience, it can be tightly pressed against the back of the dustproof plate, preventing dust from entering through the gap between the dustproof plate and the front of the chassis shell.

[0009] As a preferred implementation, the mounting frame is made of stainless steel, the dustproof plate is made of acrylic, the length of the dustproof plate matches the distance length between the two groups of disassembly slot ones, and the length of the dustproof plate matches the length of the disassembly slot two. The disassembly slot one bottom and the disassembly slot two top are connected through, and the acrylic material has good permeability, so it can not only play a dustproof effect, but also ensure permeability, so that the operator can see the information on the control panel and facilitate operation.

[0010] As a preferred implementation, the length and width of the operation window match the length and width of the control panel, a group of fixed shafts are provided on the front side of the operation window, the movable plate is movably connected outside the fixed shaft, the friction between the movable plate and the outside of the fixed shaft is greater than the weight of the movable plate, and the maximum opening angle of the movable plate upward is 120 degrees, which ensures that the movable plate will not hinder the operator's hand when passing through the operation window to operate the control panel.

[0011] As a preferred implementation, the front side of the connecting rod penetrates through the front side inner wall of the telescopic cavity and is fixed with the back of the unlocking button, the back side of the spring is provided with a baffle, and the back side of the connecting rod penetrates through the spring and is fixed with the front of the baffle.

[0012] As a preferred implementation, the radius length of the clamping head matches the radius length of the clamping hole, the distance length between the two groups of clamping heads is equal to the distance length between the two groups of clamping holes, which ensures that the clamping head and the clamping hole can match, so that the two groups of clamping heads can be inserted into the two groups of clamping holes, thereby fixing the dustproof plate inside the disassembly slot two.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting an installation frame, a dustproof plate, and a dustproof strip, the left and right sides of the dustproof plate slide downwards along the two sets of disassembly grooves on the inner side of the installation frame. During the downward sliding process, the back of the dustproof plate is pressed against the front of the dustproof strip. Since the dustproof strip is made of sponge, it can seal the gap between the dustproof plate and the front of the chassis shell, preventing dust from entering through the gap. The bottom of the dustproof plate is inserted downwards into the installation groove three. The dustproof plate is fixed by the interlocking connection of two sets of clips and two sets of clip holes, making installation convenient. By setting an unlocking button, a spring, and a connecting rod, pulling the unlocking button forward will drive the baffle to move forward inside the telescopic cavity through the connecting rod, thereby causing the baffle to move the clips forward from inside the clip holes and disengage, thus releasing the fixed state of the dustproof plate. Therefore, it is convenient to disassemble the dustproof plate. Attached Figure Description

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only some but not all embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the utility model.

[0024] Please refer to Figures 1 to 5 The switch cabinet control device with detachable dustproof structure comprises a cabinet shell 100, a mounting frame 200 and a dustproof plate 300. The mounting frame 200 is provided on the right side of the front of the cabinet shell 100 and is in a concave structure. A dismounting groove one 210 is formed on the left and right sides of the inner side of the mounting frame 200.

[0025] A dismounting groove two 220 is formed on the lower inner side of the mounting frame 200. A group of unlocking knobs 230 are arranged on the left and right sides of the front of the dismounting groove two 220. An extension cavity is formed in the inner side of the mounting frame 200 behind the unlocking knobs 230. A spring 232 is arranged in the extension cavity. A connecting rod 231 is arranged in the spring 232. A clamping head 233 is arranged on the rear side of the connecting rod 231.

[0026] The dustproof plate 300 is arranged on the inner side of the mounting frame 200. An operation window 310 is formed on the front of the dustproof plate 300. A movable plate 320 is arranged on the outer side of the operation window 310. A group of pull strips 321 are arranged on the left and right sides of the front of the movable plate 320. A dustproof strip two 311 is attached below the operation window 310. Clamping holes 330 are formed on the left and right sides of the lower front of the dustproof plate 300.

[0027] A control panel 110 is arranged on the front of the cabinet shell 100 on the inner side of the mounting frame 200. A dustproof strip one 120 is attached above the control panel 110. The thickness of the dustproof strip one 120 is greater than the distance length of the dismounting groove one 210 and the front of the cabinet shell 100.

[0028] The dustproof strip one 120 is made of sponge. The left and right sides of the dustproof strip one 120 are attached to the left and right inner sides of the mounting frame 200. The width of the dismounting groove one 210 matches the thickness of the dustproof plate 300. The thickness of the dismounting groove one 210 is the same as the thickness of the dismounting groove two 220. Since the dustproof strip one 120 is made of sponge and has good contractility and resilience, the dustproof strip one 120 can be tightly pressed against the back of the dustproof plate 300, so that dust cannot enter through the gap between the dustproof plate 300 and the front of the cabinet shell 100.

[0029] The mounting frame 200 is made of stainless steel, and the dustproof plate 300 is made of acrylic material. The length of the dustproof plate 300 matches the distance between the two groups of dismounting grooves one 210, and the length of the dustproof plate 300 matches the length of the dismounting groove two 220. The bottom of the dismounting groove one 210 is connected with the top of the dismounting groove two 220. The acrylic material has good permeability, so it can not only prevent dust but also ensure permeability, so that the operator can see the information on the control panel 110 and facilitate operation.

[0030] The length and width of the operation window 310 match the length and width of the control panel 110. A group of fixed shafts are arranged on the upper front side of the operation window 310. The movable plate 320 is movably connected to the outside of the fixed shaft. The friction between the movable plate 320 and the outside of the fixed shaft is greater than the gravity of the movable plate 320. The maximum opening angle of the movable plate 320 is 120 degrees, which ensures that the movable plate 320 will not hinder the operator's hand when passing through the operation window 310 to operate the control panel 110.

[0031] The front side of the connecting rod 231 penetrates the inner wall of the telescopic cavity and is fixed to the back of the unlocking button 230. The rear side of the spring 232 is provided with a baffle. The rear side of the connecting rod 231 penetrates the spring 232 and is fixed to the front of the baffle.

[0032] The radius of the clamping head 233 matches the radius of the clamping hole 330. The distance between the two groups of clamping heads 233 is equal to the distance between the two groups of clamping holes 330, which ensures that the clamping head 233 and the clamping hole 330 can match, so that the two groups of clamping heads 233 can be inserted into the two groups of clamping holes 330, thereby fixing the dustproof plate 300 in the dismounting groove two 220.

[0033] Embodiment 1: please refer to Figures 1 to 5 In actual use, the mounting frame 200 is pre-installed on the outside of the control panel 110 by sealing glue, so that the mounting frame 200 wraps the left and right sides and the bottom of the control panel 110 on the inside. The dustproof strip one 120 is glued above the control panel 110, and the left and right sides of the dustproof strip one 120 are glued to the left and right sides of the inside of the mounting frame 200. First, pick up the dustproof plate 300, and then align the left and right sides of the dustproof plate 300 with the dismounting grooves one 210 on the left and right sides of the mounting frame 200. Then slide the dustproof plate 300 downward, so that the dustproof plate 300 slides downward along the two groups of dismounting grooves one 210. In this process, the back of the dustproof plate 300 is always in a pressing state with the front of the dustproof strip one 120. After the bottom of the dustproof plate 300 is inserted into the dismounting groove two 220, pull the two groups of unlocking buttons 230 forward, respectively. The clamping head 233 is moved into the telescopic cavity by the connecting rod 231. At this time, the baffle presses the spring 232 to make the spring 232 contract and store energy, so as to prevent the clamping head 233 from hindering the dustproof plate 300 from being inserted into the dismounting groove two 220.

[0034] When the dustproof plate 300 is completely inserted into the dismounting groove two 220, the two sets of unlocking buttons 230 are loosened, the spring 232 rebounds to push the baffle backward, thereby pushing the clamping head 233 into the clamping hole 330, completing the position fixing of the dustproof plate 300. Since the dustproof strip one 120 is made of sponge and has good shrinkability and elasticity, the dustproof plate 300 can be tightly pressed from the back, preventing dust from entering through the gap between the dustproof plate 300 and the front of the cabinet shell 100. The left and right sides of the dustproof plate 300 are respectively slidably embedded and connected with the two sets of dismounting grooves one 210, and the bottom is embedded and connected with the dismounting groove two 220, so that the external dust pollution to the control panel 110 can be effectively prevented. When the dustproof plate 300 needs to be dismounted, only the reverse operation of the above locking steps is needed, and finally the dustproof plate 300 can be conveniently installed and dismounted, and the use is simple and convenient.

[0035] Example 2: see Figure 4 After the dustproof plate 300 is installed, the movable plate 320 can be turned forward by pinching the pull strip 321, the movable plate 320 is turned forward by 120 degrees and fixed on the front side above the operation window 310, the operation window 310 is exposed, and then the control panel 110 can be operated through the operation window 310 (the control panel 110 is prior art, and the model can be selected as needed, which will not be repeated here). At the same time, the control panel 110 can be operated at any time, which is convenient to use. After use, the movable plate 320 is turned back to the original position, at this time the back lower part of the movable plate 320 contacts the dustproof strip two 311 on the front lower part of the operation window 310. Since the movable plate 320 is connected with the fixed shaft in a damping manner, the back lower part of the movable plate 320 contacts the dustproof strip two 311 tightly when the movable plate 320 is stored on the front side of the operation window 310, preventing dust from entering and achieving the dustproof effect.

[0036] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
