Description

Technical Field

[0001] The invention relates to the technical field of moisture-proofing of outdoor terminal boxes, and in particular to a moisture-proofing mechanism and a moisture-proofing treatment method of an outdoor terminal box. Background Art

[0002] The main function of the outdoor terminal box is to transfer the status, secondary current and secondary voltage of the transformer, circuit breaker, disconnector, current transformer and voltage transformer to the measurement and control and protection devices in the protection room. On the other hand, it also provides corresponding power supply for the operation of primary equipment.

[0003] If the outdoor terminal box is placed in a humid environment, it is easy for moisture to invade the outdoor terminal box due to its own poor sealing and other reasons, resulting in moisture accumulation in the outdoor terminal box. When the temperature drops, condensation will occur, causing water droplets to condense on the wires and equipment in the box. Condensed water droplets will cause the insulation of the wires and equipment to decrease, which may eventually cause DC grounding or short circuit, as well as switch mistripping, refusal to trip and other consequences, affecting the normal operation of the equipment. In addition, if the outdoor terminal box is in a humid environment for a long time, it will also cause the metal terminals in the box and the metal parts in the relay to rust, which will lead to increased resistance, relay node blocking and other problems, which may eventually cause the secondary circuit of the current transformer to open, the terminal contact part to heat up, and the relay to fail to operate.

[0004] At present, the moisture-proof method of outdoor terminal boxes is to install heaters inside the box, use the heat generated by the heater when it is working to prevent condensation of moisture in the air, and use the air cold and hot cycle to naturally discharge the moisture out of the box. However, in actual applications, the effect of using heaters on some terminal boxes is not ideal. For example, due to the rolling of the control device, the heater keeps the heating state for a long time, which will cause abnormal heat inside the box, but aggravate the damage of moisture to the wires and equipment.

[0044] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] Figure 1 is a schematic diagram of a moisture-proof mechanism according to an embodiment of the present invention; Figure 2 It is a schematic diagram of a moisture-proof mechanism after installation according to an embodiment of the present invention.

[0047] like Figure 1 and Figure 2As shown, one embodiment of the present invention provides a moisture-proof mechanism for an outdoor terminal box, the outdoor terminal box includes a mechanism box body 300 and a connecting rod 400 that can rotate on the mechanism box body 300, and the moisture-proof mechanism includes:

[0048] The waterproof cover 100 is mounted on the connecting rod 400, and the waterproof cover 100 is fixedly connected to the mechanism box 300;

[0049] The rain cover 200 is externally mounted on the waterproof cover 100 , and the rain cover 200 is fixedly connected to the connecting rod 400 .

[0050] Among them, the moisture-proof mechanism includes a waterproof cover 100 and a rain cover 200. The waterproof cover 100 is fixedly connected to the mechanism box 300, the waterproof cover 100 is outermost on the connecting rod 400, and the waterproof cover 100 and the connecting rod 400 are matched with a gap. The rain cover 200 is fixedly connected to the connecting rod 400, the rain cover 200 is outermost on the waterproof cover 100, and a gap is left between the rain cover 200 and the mechanism box 300. Such a setting, firstly, can prevent moisture, that is, "small water" from entering the mechanism box 300 through the setting of the waterproof cover 200. The waterproof cover 200 is fixedly connected to the mechanism box 300 and cooperates with the gap of the connecting rod 400. While sealing, it will not affect the normal use of the terminal box. Then, in view of the situation that the bottom of the waterproof cover 200 is sealed and the connecting rod 400 is not sealed, a rain cover 200 is set. The rain cover 200 is fixedly connected to the connecting rod 400, and a gap is left between the rain cover 200 and the mechanism box 300 to achieve the effect of sealing the gap between the waterproof cover 200 and the connecting rod 400, which will not affect the normal use of the terminal box. Through the mutual cooperation of the rain cover 200 capping the top and the waterproof cover 100 securing the bottom, a waterproof and moisture-proof protective mechanism of the terminal box is formed, which achieves a good effect of waterproofing and moisture-proofing the terminal box without affecting the normal use of the terminal box.

[0051] Specifically, the connection part between the mechanism box 300 and the connecting rod 400 of the outdoor terminal box is the main part that causes the mechanism box 300 to be damp. By performing moisture-proof and waterproof treatment on this part, the problem of the mechanism box 300 being damp can be effectively reduced. This design effectively addresses this problem through double-layer protection. The first layer of protection is the waterproof cover 100. The method of using the waterproof cover 100 is to bond it to the mechanism box 300 through the bonding surface at the lower end of the waterproof cover 100. The bonding mainly relies on a specific adhesive. After the bonding is completed, glass glue is applied to the bonding part to ensure the tightness of the connection and extend the bonding time, that is, to extend the service life of the waterproof cover 100. Since the waterproof cover 100 is connected to the mechanism box 300 as a whole, in order to ensure the normal use of the connecting rod 400, a certain gap is maintained between the waterproof cover 100 and the connecting rod 400. The gap is usually 0.5mm to 2mm, which will not affect the normal use of the mechanism while sealing. The second layer of protection is the rain cover 200. The top of the rain cover 200 is bonded to the connecting rod 400 by an adhesive. After bonding, glass glue is applied to the bonding point to ensure the tightness of the connection and extend the bonding time, that is, to extend the service life of the rain cover 200. The lower part of the rain cover 200 maintains a certain gap with the mechanism box 300, and the gap is usually 0.5mm to 2mm, so that the gap on the top of the waterproof cover 100 can be sealed. Through the cooperation of the waterproof cover 100 and the rain cover 200, a double-layer progressive waterproof measure is realized, which can effectively protect the operating mechanism of the outdoor terminal box from rainwater entering the operating mechanism box 300, and effectively realize the moisture-proof of the mechanism box 300.

[0052] It should be noted that the internal projection of the waterproof cover 100 is circular, and the external projection can be circular, triangular, quadrilateral, polygonal or irregular. There is no limitation on the specific shape of the waterproof cover 100. Similarly, the rain cover 200 can be any shape without limitation.

[0053] Figure 3 FIG. 1 is a schematic diagram of a waterproof cover according to an embodiment of the present invention.

[0054] In a possible implementation, Figure 3 As shown, the waterproof cover 100 includes: a plurality of inner arc plates 110 connected to each other, the plurality of inner arc plates 110 enclose a first cylinder, the enclosed first cylinder is sleeved on the connecting rod 400, and the plurality of inner arc plates 110 are fixedly connected to the mechanism box 300.

[0055] Among them, the waterproof cover 100 is divided into a plurality of inner arc plates 110 that are interconnected. On the one hand, it avoids direct connection between the waterproof cover 100 and the connecting rod 400, which causes friction to the connecting rod 400 and affects the subsequent work of the connecting rod 400. On the other hand, it can also minimize the gap between the waterproof cover 100 and the connecting rod 400, thereby reducing the probability of moisture entering the mechanism box 300 through the gap. At the same time, it is more convenient for the staff to install, saves installation time, and improves the installation efficiency of the moisture-proof mechanism.

[0056] Figure 4 is a schematic diagram of a first inner arc plate according to an embodiment of the present invention; Figure 5 Schematic diagram of a second inner arc plate according to an embodiment of the present invention.

[0057] In a possible implementation, Figure 4 and Figure 5 As shown, the waterproof cover 100 includes two inner arc plates 110, namely a first inner arc plate 111 and a second inner arc plate 112. The first inner arc plate 111 and the second inner arc plate 112 enclose a first cylinder. First baffles 113 are provided on both ends of the first inner arc plate 111 facing the second inner arc plate 112, and the first baffles 113 cover the second inner arc plate 112.

[0058] Among them, the optional embodiment uses two inner arc plates 110, namely the first inner arc plate 111 and the second inner arc plate 112, reducing the number of inner arc plates 110, which can also reduce the installation time of the staff and improve the installation efficiency of the waterproof cover 100.

[0059] It should be noted that first baffles 113 are provided on both ends of the first inner arc plate 111 facing the second inner arc plate 112, that is, first baffles 113 are provided on both sides of the axial direction of the first inner arc plate 111, and the height of the first baffle 113 matches that of the inner arc plate 110. A plurality of bolt holes are provided on the first baffle 113, and a plurality of bolt holes are provided at the position of the second inner arc plate 112 corresponding to the first baffle 113. Bolts penetrate the two bolt holes to achieve the installation of the first inner arc plate 111 and the second inner arc plate 112. On the one hand, the connection reliability of the first inner arc plate 111 and the second inner arc plate 112 is guaranteed, and on the other hand, the gap of the waterproof cover 100 can be reduced to prevent moisture from entering the mechanism box 300, thereby improving the sealing effect of the waterproof cover 100.

[0060] In a feasible embodiment, the waterproof cover 100 further includes a cover plate 120, including a first cover plate 121 and a second cover plate 122, the first cover plate 121 is disposed at one end of the first inner arc plate 111 away from the mechanism box 300, and the first cover plate 121 extends toward the connecting rod 400;

[0061] The second cover plate 122 is disposed at one end of the second inner arc plate 112 away from the mechanism housing 300 , and extends toward the connecting rod 400 . The second cover plate 122 and the first cover plate 121 form a ring, and the radius of the ring is greater than the rotation radius of the connecting rod 400 .

[0062] Among them, by cooperating with the first cover plate 121 and the first inner arc plate 111, and the second cover plate 122 and the second inner arc plate 112, the gap between the waterproof cover 100 and the connecting rod 400 can be further reduced, and the collision and friction between the inner wall of the waterproof cover 100 and the connecting rod 400 can be avoided, which affects the normal operation of the connecting rod 400. In other words, the setting of the cover plate 120 can increase the gap between the inside of the waterproof cover 100 and the connecting rod 400, avoid the connecting rod 400 from touching the waterproof cover 100 when rotating, and ensure the stability and reliability of the working of the connecting rod 400.

[0063] It should be noted that the first cover plate 121 and the first inner arc plate 111 are integrally formed, and similarly, the second cover plate 122 and the second inner arc plate 112 are integrally formed. To ensure tolerance and strength of use, the wall thickness range of the waterproof cover 100 is: when the waterproof cover 100 is made of stainless steel or galvanized steel, the thickness is 0.8mm to 10mm; when the waterproof cover 100 is made of aluminum alloy, the thickness is 0.6-10mm; when the waterproof cover 100 is made of pure aluminum, the thickness is 10-12mm. If the waterproof cover 100 is too thick, the production cost of the moisture-proof mechanism will be increased. If the waterproof cover 100 is too thin, the service life of the moisture-proof mechanism and a good moisture-proof effect cannot be guaranteed.

[0064] Figure 6 A schematic diagram of a rain cover according to an embodiment of the present invention;

[0065] In a possible implementation, Figure 6 As shown, the rain cover 200 includes: a plurality of first outer arc plates 210 connected to each other, the plurality of first outer arc plates 210 enclose a second cylinder, and the outer cover of the second cylinder is disposed on the waterproof cover 100;

[0066] The shield plate 230 is disposed at one end of the first outer arc plate 210 away from the mechanism housing 300 . The shield plate 230 is a circular ring plate. The shield plate 230 is sleeved on the connecting rod 400 . The shield plate 230 is fixedly connected to the connecting rod 400 .

[0067] Similarly, the rain cover 200 is divided into a plurality of first outer arc plates 210 that are interconnected. On the one hand, this avoids direct connection between the rain cover 200 and the connecting rod 400, which would cause friction to the connecting rod 400 and affect subsequent work of the connecting rod 400. On the other hand, it can also facilitate installation by the staff, save installation time, and improve the installation efficiency of the moisture-proof mechanism.

[0068] It should be noted that, by disposing the shield 230 , the area of ​​the second cylinder can be effectively enlarged, so that the second cylinder can be covered on the first cylinder, that is, the rain cover 200 can be covered on the waterproof cover 100 .

[0069] Optionally, the shield plate 230 can be a completely annular shield plate 230. After the installation of multiple first outer arc plates 210 is completed, the shield plate is directly mounted on the connecting rod 400, and then welded to the installed multiple first outer arc plates 210. The shield plate 230 can also be multiple sub-shields, each of which is integrally formed with a first outer arc plate 210. After the multiple first outer arc plates 210 are installed, the multiple sub-shields are naturally enclosed in a circular shape and mounted on the connecting rod 400. Such a setting can reduce the installation steps, eliminate the need for welding, improve the installation efficiency of the rain cover 200, and reduce the labor intensity of the staff. Finally, after the shield plate 230 and the connecting rod 400 are bonded by an adhesive, glass glue is applied at the bonding point to achieve a good sealing effect. At the same time, it is ensured that there is a certain gap between the rain cover 200 and the structural box 300. When the rain cover 200 rotates with the connecting rod 400, it will not cause friction to the structural box 300, thereby ensuring the strength of the structural box 300.

[0070] In a feasible implementation manner, the rain cover 200 includes:

[0071] A plurality of first outer arc plates 210 connected to each other, the plurality of first outer arc plates 210 enclose a second cylinder, and the outer cover of the second cylinder is fitted on the waterproof cover 100;

[0072] The shield plate 230 is disposed at one end of the first outer arc plate 210 away from the mechanism box 300, and the shield plate 230 is a circular ring plate, and the shield plate 230 is outer-mounted on the connecting rod 400;

[0073] A plurality of second outer arc plates 220 are interconnected, and the plurality of second outer arc plates 220 enclose a third cylinder. The second outer arc plates 220 are located on the side of the shield plate 230 away from the first outer arc plate 210. The third cylinder is externally mounted on the connecting rod 400, and the second outer arc plates 220 are fixedly connected to the connecting rod 400.

[0074] Among them, through the arrangement of the second outer arc plate 220, since the second outer arc plate 220 has a certain height, the connection area between the rain cover 200 and the connecting rod 400 can be increased, and the stability of the connection can be enhanced. At the same time, since a certain gap must be left between the rain cover 200 and the mechanism box 300, a larger connection area can ensure the stability of the connection and the continuous existence of the gap, thereby avoiding the rain cover 200 from causing friction to the mechanism box 300 when the connecting rod 400 rotates, thereby affecting the strength of the mechanism box 300.

[0075] It should be noted that at this time, the number of the second outer arc plates 220 and the number of the sub-shield plates are consistent with the number of the first outer arc plates 210, and the first outer arc plates 210, the sub-shield plates and the second outer arc plates 220 are integrally formed as a support, which improves the strength of the rain cover 200 and ensures the rainproof effect of the rain cover 200.

[0076] Figure 7 is a schematic diagram of a first outer arc plate No. 1 according to an embodiment of the present invention; Figure 8 Schematic diagram of the second first outer arc plate according to an embodiment of the present invention.

[0077] In a possible implementation, Figure 7 and Figure 8 As shown, the rain cover 200 includes two first outer arc plates 210, namely, the first outer arc plate No. 1 211 and the first outer arc plate No. 2 212.

Second baffles 213 are provided on both ends of the first outer arc plate No. 1 211 facing the first outer arc plate No. 2 212, and the second baffles 213 cover the first outer arc plate No. 2 212.

[0078] Optionally, the present embodiment adopts two first outer arc plates 210, namely, first outer arc plate No. 1 211 and first outer arc plate No. 2 212, reducing the number of first outer arc plates 210, thereby reducing the installation time of the staff and improving the installation efficiency of the rain cover 200.

[0079] It should be noted that second baffles 213 are provided on both ends of the first outer arc plate 211 No. 1 facing the first outer arc plate 212, that is, second baffles 213 are provided on both sides of the axial direction of the first outer arc plate 211, and the height of the second baffle 213 matches that of the first outer arc plate 210. A plurality of bolt holes are provided on the second baffle 213, and a plurality of bolt holes are provided at the position of the first outer arc plate 212 No. 2 corresponding to the second baffle 213. Bolts penetrate the two bolt holes to realize the installation of the first outer arc plate 211 No. 1 and the first outer arc plate 212. On the one hand, the connection reliability of the first outer arc plate 211 and the second first outer arc plate 212 is guaranteed, and on the other hand, the gap of the rain cover 200 can be reduced to prevent moisture from entering between the rain cover 200 and the waterproof cover 100, thereby improving the sealing effect of the rain cover 200.

[0080] In a feasible embodiment, the baffle 230 includes a first baffle 231 and a second baffle 232, the first baffle 231 is located at one end of the first outer arc plate 211 away from the mechanism box 300, and the second baffle 232 is located at one end of the second first outer arc plate 212 away from the mechanism box 300, and the first baffle 231 and the second baffle 232 enclose a circular plate;

[0081] The number of the second outer arc plates 220 is the same as the number of the first outer arc plates 210 .

[0082] Among them, the baffle 230 includes a first baffle 231 and a second baffle 232, the first outer arc plate No. 1 211 cooperates with the first baffle 231, and the first outer arc plate No. 212 cooperates with the second baffle 232, which can ensure the interval between the rain cover 200 and the waterproof cover 100, and prevent the rain cover 200 from touching the waterproof cover 100 when the connecting rod 400 rotates, thereby ensuring the stability and reliability of the moisture-proof mechanism.

[0083] In a feasible implementation manner, the number of the first outer arc plates 210 , the shielding plates 230 , and the second outer arc plates 220 is the same, and the first outer arc plates 210 , the shielding plates 230 , and the second outer arc plates 220 are integrally formed.

[0084] Among them, the first outer arc plate 210, the shield plate 230 and the second outer arc plate 220 are integrally formed to increase the strength of the rain cover 200. To ensure tolerance and usage strength, the wall thickness range of the rain cover 200 is: when the material of the rain cover 200 is stainless steel or galvanized steel, the thickness is 0.8mm to 10mm; when the rain cover 200 is made of aluminum alloy, the thickness is 0.6-10mm; when the rain cover 200 is made of pure aluminum, the thickness is 10-12mm. If the rain cover 200 is too thick, the production cost of the moisture-proof mechanism will be increased. If the rain cover 200 is too thin, the service life of the moisture-proof mechanism and the good moisture-proof effect cannot be guaranteed.

[0085] It should be noted that the moisture-proof mechanism is made of metal materials such as stainless steel, aluminum alloy, pure aluminum, galvanized steel, etc., which are not listed one by one. It is sufficient to meet the use strength of the moisture-proof mechanism. A waterproof film can also be set on the outer wall of the waterproof cover 100 to further prevent the alternating hot and cold moisture from entering the mechanism box 300, ensure the moisture-proof effect of the moisture-proof mechanism, and then ensure the reliability and stability of the outdoor terminal box.

[0086] Example 2

[0087] Fig. 9 The figure is a flow chart of the steps of a moisture-proof treatment method according to an embodiment of the present invention.

[0088] like Fig. 9 As shown, an embodiment of the present invention provides a moisture-proof treatment method for an outdoor terminal box, using the moisture-proof mechanism of embodiment 1, the moisture-proof treatment method includes:

[0089] Step 1, setting a waterproof cover, the waterproof cover is fixedly connected to the mechanism box, and the waterproof cover is matched with the gap of the connecting rod;

[0090] Step 2, setting a rain cover, the rain cover is fixedly connected to the connecting rod, the rain cover is placed outside the waterproof cover, and a gap is left between the rain cover and the mechanism box.

[0091] Among them, the connection part between the mechanism box 300 and the connecting rod 400 of the outdoor terminal box is the main part that causes the mechanism box 300 to be damp. By performing moisture-proof and waterproof treatment on this part, the problem of the mechanism box 300 being damp can be effectively reduced. This design effectively addresses this problem through double-layer protection. The first layer of protection is the waterproof cover 100. The method of using the waterproof cover 100 is to bond it to the mechanism box 300 through the bonding surface at the lower end of the waterproof cover 100. The bonding mainly relies on a specific adhesive. After the bonding is completed, glass glue is applied at the bonding point to ensure the tightness of the connection and extend the bonding time, that is, to extend the service life of the waterproof cover 100. Since the waterproof cover 100 is connected to the mechanism box 300 as a whole, in order to ensure the normal use of the connecting rod 400, a certain gap is maintained between the waterproof cover 100 and the connecting rod 400. The gap is usually 0.5mm to 2mm. While sealing, it will not affect the normal use of the mechanism. The second layer of protection is the rain cover 200. The top of the rain cover 200 is bonded to the connecting rod 400 by an adhesive. After bonding, glass glue is applied to the bonding point to ensure the tightness of the connection and extend the bonding time, that is, to extend the service life of the rain cover 200. The lower part of the rain cover 200 maintains a certain gap with the mechanism box 300, and the gap is usually 0.5mm to 2mm, so that the gap on the top of the waterproof cover 100 can be sealed. Through the cooperation of the waterproof cover 100 and the rain cover 200, a double-layer progressive waterproof measure is realized, which can effectively protect the operating mechanism of the outdoor terminal box from rainwater entering the operating mechanism box 300, and effectively realize the moisture-proof of the mechanism box 300.

[0092] It should be noted that, since this method is obtained through the moisture-proof mechanism of Example 1, it also has all the advantages of the above-mentioned moisture-proof mechanism, which will not be repeated.
