Description

Technical Field

[0001] The present application relates to the field of switchgear, and in particular to an earthquake-resistant and condensation-proof box-type switchgear. Background Art

[0002] Box-type switchgear refers to power supply and distribution facilities used to receive and distribute electricity, which are called switch stations in high-voltage power grids. Box-type switchgear usually includes a box for installing electrical components and a door hinged to the box.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: box-type switchgear is usually installed outdoors, and when the ground vibrates, it is easy to affect the normal operation of the electrical components in the box-type switchgear, so there is room for improvement. Summary of the invention

[0004] In order to reduce the impact of ground vibration on electrical components in a box-type switchgear, the present application provides a shock-resistant and condensation-proof box-type switchgear.

[0005] A seismic and anti-condensation box-type switchgear comprises a box body and a box door hinged to the box body, a base is arranged at the lower end of the box body, a mounting plate is arranged at the upper end surface of the base, the box body is arranged on the upper end surface of the mounting plate, a connecting column is arranged on the side of the mounting plate facing the base, a connecting groove is arranged on the base for the connecting column to be inserted and slided, and a plurality of shock-absorbing parts are arranged at intervals along the circumferential direction between the mounting plate and the base.

[0006] By adopting the above technical solution, when the ground vibrates, the vibration is transmitted to the base, and the shock-absorbing component can reduce the vibration transmitted to the mounting plate, thereby reducing the vibration of the box, and further reducing the impact of the vibration on the electrical components in the box; in addition, the connecting column can provide a support for the mounting plate, and try to prevent the mounting plate from tipping over, thereby ensuring that the box on the mounting plate can operate normally.

[0007] Optionally, the shock-absorbing component includes a fixing rod, a limiting rod and a shock-absorbing spring, the fixing rod is arranged on the upper end surface of the base in the vertical direction, the limiting rod is arranged on the side of the mounting plate facing the base in the vertical direction, and the end of the fixing rod away from the base is provided with a shock-absorbing groove for the limiting rod to be inserted and slide along its own length direction, and the shock-absorbing spring is arranged between the limiting rod and the bottom wall of the shock-absorbing groove.

[0008] By adopting the above technical solution, when the ground vibrates, the base starts to vibrate, the limit rod slides up and down in the shock absorbing groove, and the shock absorbing spring can buffer part of the vibration, thereby reducing the vibration of the box.

[0009] Optionally, the circumferential outer wall of the limit rod is provided with a plurality of support bars at intervals around the axial direction of the limit rod, and the circumferential inner wall of the shock-absorbing groove is provided with a plurality of support grooves for the support bars to be inserted and slide in parallel along the length direction of the fixed rod.

[0010] By adopting the above technical solution, when the ground vibrates, the limit rod slides up and down in the shock-absorbing groove. When the vibration is more severe, the support bar on the limit rod will conflict with the inner wall of the support groove and limit the limit rod from moving further downward, thereby minimizing the limit rod from crushing the shock-absorbing spring.

[0011] Optionally, an elastic shock-absorbing pad is provided at one end of the support bar facing the base.

[0012] By adopting the above technical solution, the shock-absorbing pad can buffer a portion of the impact force between the support bar and the inner wall of the support groove, thereby extending the service life of the support bar.

[0013] Optionally, a plurality of rotation grooves are provided on the circumferential inner side wall of the connecting groove at intervals around the axial center line direction of the connecting column, and rolling wheels are rotatably provided in all the rotation grooves, and each of the rolling wheels contacts the outer side wall of the connecting column.

[0014] By adopting the above technical solution, the rolling wheel in the rotating groove can reduce the friction between the connecting column and the inner wall of the rotating groove, thereby facilitating the connecting column to slide up and down.

[0015] Optionally, a heater is provided inside the box to increase the temperature inside the box.

[0016] By adopting the above technical solution, the heater can blow out warm air, thereby increasing the temperature inside the box and the air circulation speed, thereby reducing the occurrence of condensation in the box.

[0017] Optionally, a accommodating cavity is provided in the base, the connecting groove is connected to the accommodating cavity, one end of the connecting column away from the mounting plate extends into the accommodating cavity and is provided with a fixing plate, and a side of the fixing plate away from the connecting column is provided with an elastic shock-absorbing block.

[0018] By adopting the above technical solution, when the box shakes, the connecting column slides up and down, and the shock-absorbing block on the fixed plate contacts the inner wall of the lower end of the accommodating cavity, the shock-absorbing block deforms to buffer part of the impact force, thereby further reducing the shaking of the box.

[0019] Optionally, a connecting ring is provided on the circumferential outer wall of the base, a water inlet groove is circumferentially provided on the upper end face of the connecting ring, a plurality of water inlet holes are provided on the inner wall of the water inlet groove, all of the water inlet holes are connected to the accommodating cavity, and a control button for controlling the start and stop of the heater is provided on the side of the fixing plate away from the shock-absorbing block.

[0020] By adopting the above technical solution, when it rains, rainwater enters the water inlet groove and flows into the accommodating cavity through the water inlet hole. When water enters the accommodating cavity, the shock-absorbing block floats with the water level, thereby causing the fixed plate to rise. The control button on the fixed plate contacts the upper inner wall of the accommodating cavity, thereby starting the heater, reducing the humidity in the box and reducing condensation.

[0021] Optionally, a limiting ring is circumferentially arranged on the upper end surface of the connecting ring, an end of the limiting ring away from the connecting ring is a flared end, and a plurality of precipitation grooves are evenly arranged on the inner side wall of the limiting ring.

[0022] By adopting the above technical solution, the limit ring increases the speed of collecting rainwater, so that the water level in the accommodating chamber can rise quickly, thereby increasing the starting speed of the heater; when rainwater flows down along the inner wall of the limit ring, some impurities will sink into the sedimentation tank, thereby reducing the impurities entering the accommodating chamber.

[0023] Optionally, a support ring with deformation capability is provided on a side of the fixing plate facing away from the shock absorbing block, and the support ring surrounds the outside of the control button.

[0024] By adopting the above technical solution, when the fixing plate rises, when the control button is pressed against the inner wall of the upper end of the accommodating chamber and the heater is started, the support ring will then contact the inner wall of the upper end of the accommodating chamber, thereby providing space for the control button and avoiding damage to the control button as much as possible; in addition, the support ring can reduce the impact force of the fixing plate on the inner wall of the accommodating chamber, thereby further reducing the vibration of the box.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the ground vibrates, the vibration is transmitted to the base. The shock absorber can reduce the vibration transmitted to the mounting plate, thereby reducing the vibration of the box, and further reducing the impact of the vibration on the electrical components in the box; in addition, the connecting column can provide support for the mounting plate to avoid the mounting plate from tipping over, thereby ensuring that the box on the mounting plate can operate normally.

[0027] 2. When the ground vibrates, the limit rod slides up and down in the shock absorbing groove. When the vibration is more severe, the support strip on the limit rod will conflict with the inner wall of the support groove and restrict the limit rod from moving further downward, thereby minimizing the limit rod from crushing the shock absorbing spring.

[0028] 3. When it rains, rainwater enters the water inlet groove and flows into the accommodating chamber through the water inlet hole. When water enters the accommodating chamber, the shock-absorbing block floats with the water level, thereby causing the fixed plate to rise. The control button on the fixed plate contacts the upper inner wall of the accommodating chamber, thereby starting the heater, reducing the humidity in the box and reducing condensation.

[0029] 4. The limit ring increases the speed of collecting rainwater, so that the water level in the containing chamber can rise quickly, thereby increasing the starting speed of the heater; when rainwater flows down along the inner wall of the limit ring, some impurities will sink into the sedimentation tank, thereby reducing the impurities entering the containing chamber.

[0030] 5. When the fixing plate rises, when the control button is pressed against the inner wall of the upper end of the accommodating chamber and the heater is started, the support ring will then come into contact with the inner wall of the upper end of the accommodating chamber, thereby providing space for the control button and avoiding damage to the control button as much as possible; in addition, the support ring can reduce the impact force of the fixing plate on the inner wall of the accommodating chamber, thereby further reducing the vibration of the box.

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The present application embodiment discloses a seismic and condensation-proof box-type switchgear. Figure 1 and Figure 2, including a box body 1 and a door 2 hinged to the box body 1, a heater for increasing the internal temperature of the box body 1 is installed in the box body 1. A rectangular base 3 is installed at the lower end of the box body 1, a rectangular mounting plate 4 is arranged on the upper end surface of the base 3, the mounting plate 4 is arranged horizontally, the box body 1 is fixedly mounted on the upper end surface of the mounting plate 4, and eight shock absorbing members 6 are arranged at intervals along the circumferential direction between the mounting plate 4 and the base 3. When the ground vibrates, the shock absorbing member 6 can reduce the vibration of the box body 1.

[0040] Reference Figure 2 and Figure 3 The shock absorbing member 6 includes a fixing rod 61, a limiting rod 62 and a shock absorbing spring 63. The fixing rod 61 is fixedly connected to the upper end surface of the base 3 in the vertical direction. The limiting rod 62 is fixedly connected to the side of the mounting plate 4 facing the base 3 in the vertical direction. The end of the fixing rod 61 away from the base 3 is provided with a shock absorbing groove 611 for the limiting rod 62 to insert and slide along its length direction. The shock absorbing spring 63 is fixedly connected between the limiting rod 62 and the bottom wall of the shock absorbing groove 611. When the ground vibrates, the base 3 starts to vibrate, the limiting rod 62 slides up and down in the shock absorbing groove 611, and the shock absorbing spring 63 can buffer part of the vibration.

[0041] Reference Figure 2 and Figure 3 The circumferential outer wall of the limit rod 62 is fixedly connected with four support bars 621 at intervals around the axis direction of the limit rod 62, and the circumferential inner wall of the shock absorbing groove 611 is penetrated in parallel along the length direction of the fixed rod 61 and is provided with four support grooves 612 for the support bars 621 to be inserted and slide. A shock absorbing pad 622 made of silicone material is fixedly connected to one end of the support bar 621 facing the base 3. When the ground vibrates, the limit rod 62 slides up and down in the shock absorbing groove 611. When the vibration is more severe, the support bar 621 on the limit rod 62 will conflict with the inner wall of the support groove 612 and limit the limit rod 62 from continuing to move downward, thereby preventing the limit rod 62 from crushing the shock absorbing spring 63 as much as possible.

[0042] Reference Figure 4 and Figure 5 A connecting column 5 with a rectangular cross section is vertically fixedly connected to the middle of the side of the mounting plate 4 facing the base 3, and a connecting groove 31 with a rectangular cross section is provided on the base 3 for the connecting column 5 to be inserted and slide. Rotation grooves 32 are provided on the inner side walls around the connecting groove 31, and rolling wheels 7 are rotatably connected in all the rotating grooves 32, and each rolling wheel 7 is in contact with the outer side wall of the connecting column 5. The connecting column 5 can provide a support for the mounting plate 4 to prevent the mounting plate 4 from tipping over as much as possible; the rolling wheel 7 in the rotating groove 32 can reduce the friction between the connecting column 5 and the inner wall of the rotating groove 32, thereby facilitating the connecting column 5 to slide up and down.

[0043] Reference Figure 1 and Figure 4 The base 3 is provided with a receiving cavity 33, and the connecting groove 31 is connected with the receiving cavity 33. The end of the connecting column 5 away from the mounting plate 4 extends into the receiving cavity 33 and is vertically fixedly connected with a rectangular fixing plate 8. The side of the fixing plate 8 away from the connecting column 5 is fixedly connected with a shock absorbing block 81. The shock absorbing block 81 is made of TPE foam material, so the shock absorbing block 81 has good elasticity and can float in water. When the shock absorbing block 81 on the fixing plate 8 contacts the inner wall of the lower end of the receiving cavity 33, the shock absorbing block 81 is deformed to buffer part of the impact force, thereby further reducing the shaking of the box body 1.

[0044] Reference Figure 4 and Figure 5 A control button 82 for controlling the opening and closing of the heater is installed on one side of the fixing plate 8 away from the shock absorbing block 81. A support ring 83 made of silicone material is fixedly connected to one side of the fixing plate 8 away from the shock absorbing block 81, and the support ring 83 surrounds the outside of the control button 82.

[0045] Reference Figure 1 , Figure 4 and Figure 5 The circumferential outer wall of the base 3 is fixedly connected with a connecting ring 9, and a water inlet groove 91 is opened in the upper end face of the connecting ring 9 along the circumferential direction, and a plurality of water inlet holes 92 are opened in the inner side wall of the water inlet groove 91, and all water inlet holes 92 are connected with the accommodating chamber 33. A limiting ring 93 is inserted in the upper end face of the connecting ring 9 along the circumferential direction, and the end of the limiting ring 93 away from the connecting ring 9 is a flared end, and a plurality of sedimentation grooves 931 are evenly opened in the inner side wall of the limiting ring 93. After the limiting ring 93 is inserted on the connecting ring 9, the rotation of the box door 2 can be limited, thereby preventing the box door 2 from being accidentally opened. The limiting ring 93 can increase the collection speed of rainwater, so that the water level in the accommodating chamber 33 can rise rapidly. When the water level in the accommodating chamber 33 rises, the shock-absorbing block 81 drives the fixing plate 8 to float up, and the control button 82 first presses against the inner wall of the upper end of the accommodating chamber 33 and starts the heater, and then the support ring 83 contacts the inner wall of the upper end of the accommodating chamber 33, thereby providing space for the control button 82 and avoiding damage to the control button 82 as much as possible; in addition, the support ring 83 can reduce the impact force of the fixing plate 8 on the inner wall of the accommodating chamber 33, thereby further reducing the vibration of the box body 1.

[0046] The implementation principle of the earthquake-resistant and condensation-proof box-type switchgear of the embodiment of the present application is as follows: when the ground vibrates, the base 3 starts to vibrate, the limit rod 62 slides up and down in the shock-absorbing groove 611, and the shock-absorbing spring 63 can buffer part of the vibration, thereby reducing the vibration of the box body 1;

[0047] When it rains outside, rainwater enters the accommodating chamber 33 through the water inlet hole 92. When the fixing plate 8 rises, the control button 82 is pressed against the inner wall of the upper end of the accommodating chamber 33 and the heater is started, thereby increasing the temperature inside the box 1 and enhancing the air circulation inside the box 1, reducing the entry of water vapor into the box 1.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
