In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figures 1 to 4As shown, this embodiment provides an electrical equipment protection device, which not only isolates the electrical equipment 100 from the surrounding environment, but also facilitates the staff to replace and repair the electrical equipment 100, thereby improving the practicality of the electrical equipment protection device.

[0042] See also Figure 1 and Figure 4 The electrical equipment protection device includes a shell 2, a cover 1, a packing seal 7 and a locking mechanism. The shell 2 and the cover 1 are rotatably connected. The cover 1 has a first state locked with the shell 2 and a second state unlocked with the shell 2. In the first state, the shell 2 and the cover 1 are surrounded to form a sealed installation space, and the electrical equipment 100 can be installed in the installation space; in the second state, the cover 1 can rotate relative to the shell 2 and form an opening 3 between the cover 1 and the shell 2, and the electrical equipment 100 can be placed in the installation space or taken out from the installation space through the opening 3. The shell 2 is provided with a wiring port 21, and the installation space is connected with the wiring port 21; the packing seal 7 is passed through the wiring port 21, and the cable 101 of the electrical equipment 100 can pass through the packing seal 7 in a sealed manner; the locking mechanism is provided on the cover 1 and / or the shell 2. In the first state, the cover 1 is locked with the shell 2 through the locking mechanism.

[0043] The electrical equipment protection device provided in this embodiment has a locking mechanism on the cover 1 and / or the housing 2, and the cover 1 can be locked with the housing 2 through the locking mechanism. At this time, the electrical equipment 100 can be installed in a sealed installation space, and the cable 101 of the electrical equipment 100 can extend through the wiring port 21 and seal with the packing seal 7 penetrating the wiring port 21, and the packing seal 7 ensures the sealing of the installation space. That is, in the first state, the electrical equipment protection device can isolate the electrical equipment 100 from the surrounding humid environment, ensuring the safety of the electrical equipment 100 during operation. When the housing 2 and the cover 1 are unlocked, the cover 1 can form an opening 3 with the housing 2 by rotating, and the staff can take out or put in the electrical equipment 100 through the opening 3, and can also enter the housing 2 through the opening 3 to repair the electrical equipment 100, thereby improving the practicality of the electrical equipment protection device. In addition, the setting of the wiring port 21 enables the cable 101 of the electrical equipment 100 to extend out of the installation space to connect with other equipment, so as to avoid affecting the normal use of the electrical equipment 100.

[0044] In this embodiment, the cover body 1 is made of a transparent material, such as glass. The staff can see the situation in the installation space through the cover body 1 without unlocking the cover body 1 and the shell 2, which makes it easier for the staff to control the working status of the electrical equipment 100.

[0045] Further, see Figure 1The shell 2 is provided with supporting legs 4 on the side away from the cover 1, and the shell 2 is fixed to the cabin wall 200 through the supporting legs 4. Specifically, the cross-sectional shape of the shell 2 is rectangular, and the four corners of the shell 2 on the side away from the cover 1 are provided with supporting legs 4, which are made of steel and welded to the cabin wall 200 to firmly fix the electrical equipment protection device to the cabin wall 200.

[0046] Exemplarily, the cover 1 and the housing 2 are made of insulating and corrosion-resistant materials, such as resin-based composite materials, which can not only prevent the electrical equipment 100 located in the installation space from being affected by the surrounding humid environment, but also ensure the safety of the staff when using it.

[0047] In this embodiment, refer to Figure 1 The electrical device 100 has two cables 101 . The housing 2 is provided with two wiring ports 21 . The two cables 101 pass through the two wiring ports 21 in a one-to-one correspondence.

[0048] In an alternative embodiment, see Figure 1 The locking mechanism includes a first locking assembly 51 and a second locking assembly 52 which can be separated or snapped together. The first locking assembly 51 is arranged on the cover 1, and the second locking assembly 52 is arranged on the shell 2. In the first state, the first locking assembly 51 and the second locking assembly 52 are snapped together to lock the cover 1 and the shell 2; in the second state, the first locking assembly 51 and the second locking assembly 52 are separated to separate the cover 1 and the shell 2. The first locking assembly 51 and the second locking assembly 52 are connected by snapping together, so that the locking and unlocking operations of the cover 1 and the shell 2 are convenient and quick, so that the electrical equipment protection device can be more suitable for scenes with poor working environments such as cabins.

[0049] Specifically, the staff drives the cover body 1 to rotate relative to the shell 2 until the cover body 1 contacts the shell 2 along its circumference. At this time, the first locking component 51 and the second locking component 52 are engaged to put the cover body 1 and the shell 2 in a locked state; when the electrical equipment 100 needs to be replaced or repaired, the first locking component 51 and the second locking component 52 are driven to release the engagement, and the cover body 1 and the shell 2 are unlocked. At this time, the cover body 1 is rotated in a direction away from the shell 2, and an opening 3 will be formed between the cover body 1 and the shell 2 to repair and replace the electrical equipment 100.

[0050] In this embodiment, the first locking assembly 51 includes a first mounting member and a hook, the first mounting member is fixed to the cover body 1, and the hook is rotatably connected to the first mounting member. The second locking assembly 52 includes a second mounting member and an elastic member, the second mounting member is fixed to the shell 2, a slot is provided on the second mounting member, a movable slider is provided in the slot, the elastic member is limited between the slot wall of the slot and the slider, and the slider has a connection position abutting against the hook and a avoidance position avoiding the hook; when the hook rotates, the hook can extend into the slot and push the slider to move toward the avoidance position, and the elastic member is in a compressed energy storage state; after the hook rotates to a preset position, the slider can move to the connection position under the elastic action of the elastic member. When the slider moves to the connection position, the elastic member is still in a deformed state, so that the slider can maintain abutment with the hook under the elastic force of the elastic member, so that the cover body 1 and the shell 2 can be maintained in a locked state; after the hook is disengaged from the slot by rotation, the position of the cover body 1 is no longer constrained, the cover body 1 is separated from the shell 2, and the cover body 1 can rotate relative to the shell 2. Such a configuration makes the locking and separation operations of the cover body 1 and the housing 2 convenient and quick, and when the electrical equipment protection device is accidentally touched, the cover body 1 and the housing 2 will not be easily separated, thereby improving the applicability of the electrical equipment protection device. When the hook claw rotates to a preset position, the hook claw contacts the second mounting member, and the second mounting member restricts the hook claw from continuing to rotate.

[0051] Specifically, after the shell 2 is rotated to contact the shell 2 along its circumference, the hook is rotated in the direction close to the second mounting part, and one end of the hook with a hook can be inserted into the slot and push the slider to move in the direction away from the hook, and the elastic member is deformed and generates elastic force. At this time, the slider is simultaneously subjected to the elastic force in the opposite direction and the thrust force of the hook, and the thrust force is greater than the elastic force, so that the slider can move toward the avoidance position; after the hook is rotated to the preset position, the slider moves to the avoidance position, at which time the hook no longer rotates and no longer applies thrust force to the slider, so that the slider moves in the direction close to the hook under the elastic force of the elastic member and abuts against the hook, completing the locking of the cover 1 and the shell 2. When the cover 1 and the shell 2 need to be unlocked, the staff drives the hook to rotate in the direction away from the second mounting part, and the hook pushes the slider to move toward the avoidance position again, until the hook of the hook is separated from the slider and removed from the slot, and the cover 1 and the shell 2 are unlocked.

[0052] In this embodiment, the hook claw is an L-shaped structure, including a first hook claw section and a second hook claw section that are connected. The end of the first hook claw section away from the second hook claw section is rotatably connected to the first mounting member through an axis, and a bent hook is provided at the end of the second hook claw section away from the first hook claw section. After the hook claw rotates to a preset position, the first hook claw section contacts the surface of the second mounting member, and the second mounting member restricts the hook claw from continuing to rotate in a direction approaching the second mounting member, so that the bent hook of the hook claw no longer continues to push the sliding block.

[0053] Exemplarily, the first mounting member and the second mounting member are both mounting plates or mounting blocks, and the elastic member is a spring.

[0054] In another optional embodiment, the locking mechanism includes an adsorption member, which is arranged on the cover body 1 and / or the shell 2. The cover body 1 is locked with the shell 2 through the adsorption member, so that the locking and separation of the shell 2 and the cover body 1 are more convenient and easier to operate.

[0055] In this embodiment, adsorbents are provided on both the cover body 1 and the shell 2. The adsorbents are magnetic blocks, and the magnetism of the adsorbent provided on the cover body 1 is opposite to the magnetism of the adsorbent provided on the shell 2. When the cover body 1 is rotated until its circumference is in contact with the shell 2, the two adsorbents with opposite magnetism can adsorb each other to lock the cover body 1 and the shell 2.

[0056] In some embodiments, an adsorption member is provided on one of the cover body 1 or the shell 2, and a magnetic block corresponding to the position of the adsorption member is provided on the other. The adsorption member is an electromagnet block that can generate a magnetic field. When the electromagnet block is energized, the electromagnet block generates a magnetic field, and the magnetic block can be magnetically attracted to the electromagnet block to lock the cover body 1 and the shell 2; when the electromagnet block is powered off, the magnetic field of the electromagnet block disappears, and the electromagnet block no longer magnetically attracts the magnetic block, thereby releasing the cover body 1 from the shell 2, and the cover body 1 can be separated from the shell 2.

[0057] Optionally, see Figure 3 The electrical equipment protection device also includes a first connecting plate 61, a rotating shaft (not shown in the figure) and a second connecting plate 62. The first connecting plate 61 is fixedly connected to the cover body 1, and the second connecting plate 62 is fixedly connected to the shell 2. The first connecting plate 61 and the second connecting plate 62 are both rotatably connected to the rotating shaft. When the first connecting plate 61 rotates relative to the second connecting plate 62 through the rotating shaft, the first connecting plate 61 can drive the cover body 1 to rotate relative to the shell 2 fixedly connected to the second connecting plate 62, that is, the cover body 1 and the shell 2 are rotatably connected through the first connecting plate 61, the rotating shaft and the second connecting plate 62.

[0058] Specifically, the first connecting plate 61 is provided with a first rotation groove extending along the axial direction of the rotating shaft, and the second connecting plate 62 is provided with a second rotation groove extending along the axial direction of the rotating shaft. The rotating shaft passes through the first rotation groove and the second rotation groove in sequence, so that the first connecting plate 61 and the second connecting plate 62 can both rotate around the axial direction of the rotating shaft. Furthermore, both ends of the rotating shaft are provided with limit members, and the cross-sectional dimensions of the limit members are larger than the cross-sectional dimensions of the first rotation groove and the second rotation groove, so that the rotating shaft will not be separated from the first rotation groove and the second rotation groove.

[0059] Exemplarily, the cover body 1 and the housing body 2 are rotatably connected via a hinge, the first connecting plate 61 and the second connecting plate 62 are blades of the hinge, and the rotating shaft is the shaft pin of the hinge.

[0060] In this embodiment, the first connecting plate 61 is fixedly connected to the cover body 1 by bolts or screws, and the second connecting plate 62 is fixedly connected to the housing 2 by bolts or screws.

[0061] In some embodiments, along the height direction of the cover body 1 ( Figure 3 in the X direction) or in the width direction ( Figure 3 In the Y direction, multiple first connecting plates 61, multiple rotating shafts and multiple second connecting plates 62 are arranged at intervals. The multiple first connecting plates 61 and the multiple second connecting plates 62 correspond to the multiple rotating shafts one by one, which makes it easier for the cover body 1 to rotate relative to the shell body 2 and ensures the stability of the rotation of the cover body 1.

[0062] Optionally, the packing seal 7 includes a packing sleeve that is inserted into the wiring port, and the packing sleeve is filled with a packing material, and the cable of the electrical device can pass through the packing sleeve and is in close contact with the inner wall of the packing sleeve through the packing material. After the cable 101 passes through the packing sleeve, the packing material filled in the packing sleeve can fill the space between the inner wall of the packing sleeve and the cable 101, so that the packing sleeve and the cable 101 can be in close contact, and there is no gap between the packing sleeve and the cable 101, so that the cable 101 passes through the wiring port 21 in a sealed manner, thereby ensuring the sealing of the installation space and preventing the electrical device 100 from being affected by a humid environment.

[0063] Exemplarily, the filler is made of a flexible, tightly structured and waterproof material, such as rubber, epoxy resin putty, etc. The shape of the filler is not fixed so that it can be filled between the cable 101 and the inner wall of the filler sleeve; the filler has a tight structure and is waterproof, so that water vapor will not pass through the filler into the installation space, thereby ensuring the sealing of the installation space.

[0064] In some embodiments, because different electrical devices 100 have different numbers of cables 101, the housing 2 is provided with a plurality of wiring ports 21. The electrical device 100 can pass the cables 101 through the filler sleeves of the corresponding wiring ports 21 according to the positions of other devices connected thereto, thereby improving the applicability of the electrical device protection device. When the number of wiring ports 21 is greater than the number of cables 101, the filler can block the filler sleeves that are not penetrated with the cables 101 to ensure the sealing of the installation space.

[0065] Optionally, the packing seal 7 further includes a pressing member and a first gasket, an inner step surface is provided on the packing sleeve, the first gasket is movably provided in the packing sleeve along the axial direction of the packing sleeve, the filler is located between the first gasket and the inner step surface, the pressing member is movably provided in the packing sleeve along the axial direction of the packing sleeve, when the pressing member is driven to move, the pressing member can contact with the first gasket and push the first gasket to press the filler against the inner step surface, so that the filler between the first gasket and the inner step surface is kept in a tight state, thereby ensuring the sealing of the installation space. The provision of the first gasket enables the concentrated force generated by the pressing member to be converted into a uniform force acting on the filler, thereby increasing the pressure area of ​​the filler, so that the filler at each position between the first gasket and the inner step surface can be compressed.

[0066] Furthermore, a second gasket is provided in the packing sleeve, and the second gasket is fixed to the inner step surface. When the pressing member is driven to move, the pressing member can contact the first gasket and push the first gasket to press the packing material against the second gasket, and then press it against the inner step surface. The second gasket can effectively support the packing material at the inner step surface to ensure that the packing material can be clamped between the first gasket and the second gasket.

[0067] In this embodiment, the first gasket and the second gasket are both provided with through holes matching the size of the cable 101. The cable 101 entering the installation space passes through the through hole of the second gasket, the filler and the through hole of the first gasket in sequence, and the filler will not overflow from the through hole after being compressed.

[0068] For example, the clamping member is a bolt, an internal thread is provided on the inner wall of the packing sleeve, the rod of the bolt extends into the packing sleeve and matches with the internal thread, and the head of the bolt is located outside the packing sleeve so that the staff can drive the bolt to move. When the bolt is screwed, the rod of the bolt can move along the axial direction of the packing sleeve to push the first gasket.

[0069] Furthermore, an adjusting member is provided at one end of the packing sleeve extending into the installation space, and an outer step surface is also provided on the packing sleeve, and the adjusting member and the outer step surface cooperate to fix the packing sleeve at the wiring port 21. Specifically, the adjusting member is a nut, and the packing sleeve includes a first sleeve section and a second sleeve section connected to each other, and the size of the first sleeve section is larger than the size of the second sleeve section, and an outer step surface and an inner step surface are formed at the connection between the first sleeve section and the second sleeve section, and the first sleeve section is located outside the installation space, and the inner wall of the first sleeve section is provided with a thread, and the pressing member is threadedly matched with the first sleeve section to compress the packing material, and the second sleeve section passes through the wiring port 21 and extends into the installation space, and the outer wall of the second sleeve section is provided with a thread, and the adjusting member is threadedly matched with the second sleeve section to limit the packing sleeve at the wiring port 21.

[0070] In an alternative embodiment, see Figure 1 and Figure 4The electrical equipment protection device also includes a fastener. A first connecting hole 22 is provided on the housing 2. The fastener passes through the first connecting hole 22 and is threadedly connected to the electrical equipment 100 to firmly fix the electrical equipment 100 to the electrical equipment protection device.

[0071] Specifically, see Figure 1 The fastener (not shown in the figure) is provided with an external thread, and the electrical device 100 is provided with a connecting ear plate 102. The connecting ear plate 102 is provided with a first threaded hole 103 that matches the fastener thread. The fastener passes through the first connecting hole 22 and is fastened to the first threaded hole 103 to connect the electrical device 100 to the housing 2.

[0072] Illustratively, the fastener is a bolt or a screw.

[0073] Furthermore, the electrical equipment protection device also includes a sealing ring arranged in the first connecting hole 22, and the first connecting hole 22 is sealed and connected to the fastener through the sealing ring, so that after the electrical equipment 100 is installed on the shell 2, the installation space is still in a sealed state, preventing the electrical equipment 100 from being affected by the surrounding humid air.
