Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to an energy storage cabinet and an energy storage system. Background Art

[0002] Energy storage cabinets are usually placed outdoors. When the environment is harsh or a flood occurs, it is very easy for water to enter the energy storage cabinet or submerge the energy storage cabinet. If it is not handled in time, it will cause an electrical short circuit inside the energy storage cabinet, thereby causing a safety accident. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides an energy storage cabinet and an energy storage system, which can promptly detect when water enters the energy storage cabinet, thereby improving the safety of the energy storage cabinet.

[0004] In order to solve the above technical problems, in a first aspect, the utility model provides an energy storage cabinet, which includes:

[0005] Cabinet;

[0006] A non-contact water immersion sensor, wherein the detection head of the non-contact water immersion sensor faces the bottom of the cabinet;

[0007] A load-bearing bracket and a clamping bracket, wherein the load-bearing bracket is fixed in the cabinet, and the non-contact water immersion sensor is arranged on the load-bearing bracket and between the clamping bracket;

[0008] A fastening assembly, wherein the fastening assembly is used to connect the clamping bracket to the supporting bracket, so that the clamping bracket and the supporting bracket clamp the non-contact water immersion sensor.

[0009] Since the detection head of the non-contact water immersion sensor emits light toward the bottom of the cabinet, the non-contact water immersion sensor can detect whether water has entered the bottom of the cabinet. Since the bearing bracket is fixed in the cabinet, the non-contact water immersion sensor is arranged between the bearing bracket and the clamping bracket, and the fastening component is used to connect the clamping bracket to the bearing bracket. On the one hand, the non-contact water immersion sensor can be fixed in the cabinet by the bearing bracket and the clamping bracket, thereby avoiding the non-contact water immersion sensor from moving or rotating when the cabinet moves, and ensuring the effect of fixing the non-contact water immersion sensor relative to the cabinet. On the other hand, when installing the non-contact water immersion sensor, the non-contact water immersion sensor is first located between the bearing bracket and the clamping bracket, and then the clamping bracket is connected to the bearing bracket by the fastening component. In this way, the distance between the bearing bracket and the clamping bracket can be appropriately adjusted according to the specifications of the non-contact water immersion sensor, thereby facilitating the fixed installation of the non-contact water immersion sensor and being suitable for the fixation of non-contact water immersion sensors of various specifications.

[0010] In addition, compared with the solution of using a water immersion detection rope to detect whether water has entered the bottom of the cabinet, fixing the non-contact water immersion sensor in the cabinet by means of a load-bearing bracket and a clamping bracket can ensure the cleanliness of the cabinet.

[0011] In some possible embodiments, the supporting bracket is provided with a first embracing portion and a plurality of first connecting portions, and the plurality of first connecting portions are respectively located at two opposite sides of the first embracing portion;

[0012] The clamping bracket is provided with a second clamping portion and a plurality of second connecting portions, the plurality of second connecting portions are respectively located at opposite sides of the second clamping portion, and the plurality of second connecting portions correspond to the plurality of first connecting portions one by one, and the portion of the non-contact water immersion sensor is located between the first clamping portion and the second clamping portion;

[0013] The fastening assembly includes a plurality of fasteners, each of which connects one of the second connecting parts and the corresponding first connecting part, so that the first clamping part and the second clamping part clamp the non-contact water immersion sensor.

[0014] Since multiple first connecting parts are respectively located on the opposite sides of the first clamping part, and multiple second connecting parts are respectively located on the opposite sides of the second clamping part, part of the non-contact water immersion sensor is located between the first clamping part and the second clamping part, and each fastener connects a second connecting part and a corresponding first connecting part, it is possible to fasten the non-contact water immersion sensor on the opposite sides, thereby improving the effect of fastening the non-contact water immersion sensor.

[0015] In addition, by providing multiple first connection parts, multiple second connection parts and multiple fasteners, and the multiple first connection parts correspond one-to-one with the multiple second connection parts and the multiple fasteners, multiple fastening points can be provided to ensure the fastening effect of the non-contact water immersion sensor.

[0016] In some possible embodiments, the shape of the clamping surface of the first clamping portion matches the outer contour of the non-contact water immersion sensor; and / or,

[0017] The shape of the clamping surface of the second clamping portion matches the outer contour of the non-contact water immersion sensor.

[0018] Therefore, by matching the shape of the clamping surface of the first clamping part with the outer contour of the non-contact water immersion sensor, the contact area between the first clamping part and the non-contact water immersion sensor can be increased. Similarly, by matching the shape of the clamping surface of the second clamping part with the outer contour of the non-contact water immersion sensor, the contact area between the second clamping part and the non-contact water immersion sensor can be increased, thereby improving the fixing effect of the supporting bracket and the clamping bracket on the non-contact water immersion sensor.

[0019] In some possible embodiments, the energy storage cabinet further includes a control module;

[0020] The non-contact water immersion sensor includes a conical detection head and a cylindrical body connected to each other, the conical detection head is located in the installation space formed by the supporting bracket and the clamping bracket, the cylindrical body is located between the first clamping part and the second clamping part, and a feedback component communicatively connected to the conical detection head is arranged in the cylindrical body, and the feedback component is communicatively connected to the control module.

[0021] Since the conical detection head is located in the installation space formed by the bearing bracket and the clamping bracket, and the cylindrical body is located between the first clamping part and the second clamping part, on the one hand, since the outer diameters of the cylindrical body are the same, the design of the first clamping part and the second clamping part is simplified, and at the same time, the connection stability between the first clamping part and the second clamping part and the cylindrical body is guaranteed; on the other hand, since the conical detection head is located in the installation space formed by the bearing bracket and the clamping bracket, a larger part of the structure of the non-contact water immersion sensor is located in the installation space, thereby further improving the stability of the non-contact water immersion sensor fixed in the cabinet.

[0022] In some possible embodiments, a first connecting through hole is provided on the first connecting portion, and a second connecting through hole is provided on the second connecting portion;

[0023] The fastener includes a bolt and a nut matched with the bolt, the bolt includes a bolt head and a screw rod connected to each other, the screw rod is passed through the first connecting through hole and the corresponding second connecting through hole, and the nut is tightened on a section of the screw rod away from the bolt head.

[0024] Since bolts and nuts can be purchased directly and are relatively low in cost, fastening the first connecting part and the second connecting part with bolts and nuts can, on the one hand, reduce the cost of fixing the non-contact water immersion sensor, and on the other hand, simplify the structure of fastening the first connecting part and the second connecting part.

[0025] In some possible embodiments, when the first embracing portion and the second embracing portion embracing the non-contact water immersion sensor, a gap is provided between the first connecting portion and the corresponding second connecting portion.

[0026] Since there is a gap between the first connection part and the corresponding second connection part when the first clamping part and the second clamping part clamp the non-contact water immersion sensor, on the one hand, when the fastener fastens the first clamping part and the second clamping part, the first clamping part and the second clamping part can clamp the non-contact water immersion sensor, and on the other hand, the first clamping part and the second clamping part can clamp non-contact water immersion sensors of different specifications, thereby improving the applicability of the bearing bracket and the clamping bracket for fixing the bearing bracket and the clamping bracket.

[0027] In some possible embodiments, the fastening assembly is connected to the top of the load-bearing bracket and the top of the holding bracket;

[0028] The energy storage cabinet also includes a connecting piece, which is connected to the side wall of the load-bearing bracket and the side wall of the clamping bracket.

[0029] Since the fastening assembly is connected to the top of the load-bearing bracket and the top of the clamping bracket, in order to improve the stability of the clamping bracket relative to the load-bearing bracket, the connecting piece is connected to the side wall of the load-bearing bracket and the side wall of the clamping bracket.

[0030] In some possible embodiments, a waist-shaped hole is provided on the side wall of the clamping bracket, and the length direction of the waist-shaped hole is parallel to the clamping direction of the clamping bracket and the load-bearing bracket;

[0031] A connecting hole is arranged on the side wall of the bearing bracket, and one end of the connecting member passes through the waist-shaped hole and is connected to the connecting hole.

[0032] Therefore, by providing waist-shaped holes on the side walls of the clamping bracket, the installation accuracy of the clamping bracket on the carrying bracket can be reduced when the clamping bracket is connected to the carrying bracket.

[0033] In some possible embodiments, the supporting bracket has a first side wall and a second side wall opposite to each other, the connecting hole is located on the first side wall, and a clamping groove is provided on the second side wall;

[0034] A clamping protrusion is arranged on the top of the clamping bracket, and the clamping protrusion cooperates with the clamping groove.

[0035] Since the connecting hole is located on the first side wall, when the connecting piece passes through the waist-shaped hole and is connected to the connecting hole, the first side wall of the supporting bracket can be fixedly connected to the clamping bracket. In addition, since a snap-in groove is provided on the second side wall and a snap-in protrusion is provided on the top of the clamping bracket, the snap-in protrusion cooperates with the snap-in groove, so the second side wall of the supporting bracket is fixedly connected to the clamping bracket, thereby further improving the stability of the clamping bracket and the supporting bracket in clamping the non-contact water immersion sensor.

[0036] In some possible embodiments, a mounting portion is further provided on the second side wall, and the mounting portion is used to be connected to the inner side wall of the cabinet.

[0037] Since the mounting portion is connected to the inner wall of the cabinet, the supporting bracket can be fixed on the inner wall of the cabinet, and the structure is simple and easy to install.

[0038] In some possible embodiments, the light-transmitting hole is formed on the bottom wall of the supporting bracket, and the light-emitting surface of the non-contact water immersion sensor faces the light-transmitting hole.

[0039] Since the light emitting surface of the non-contact water immersion sensor is opposite to the light transmission hole, the outgoing light of the non-contact water immersion sensor can be emitted to the bottom of the cabinet through the light transmission hole, and the reflected light can pass through the light transmission hole. If there is no water ingress into the bottom of the cabinet, the reflected light can be received by the non-contact water immersion sensor. Otherwise, the reflected light cannot be received, thereby obtaining the detection result of whether water has entered the bottom of the cabinet.

[0040] In some possible embodiments, the distance between the light emitting surface of the non-contact water immersion sensor and the bottom of the cabinet is d, and 2 mm≤d≤4 mm.

[0041] If the distance between the light emitting surface of the non-contact water immersion sensor and the bottom of the cabinet is less than 2 mm, then when water enters the bottom of the cabinet, the non-contact water immersion sensor is very easy to be soaked by the water, thereby affecting the service life of the non-contact water immersion sensor. If the distance between the light emitting surface of the non-contact water immersion sensor and the bottom of the cabinet is greater than 4 mm, then the distance between the bottom of the cabinet and the detection head of the non-contact water immersion sensor is too large, thereby affecting the detection accuracy of the non-contact water immersion sensor. Therefore, when the distance between the light emitting surface of the non-contact water immersion sensor and the bottom of the cabinet is between 2 mm and 4 mm, both the service life and the detection accuracy of the non-contact water immersion sensor can be guaranteed.

[0042] In a second aspect, the utility model further provides an energy storage system, comprising the energy storage cabinet described in any one of the first aspects.

[0043] Since the energy storage system includes the energy storage cabinet of the first aspect, the stability of the operation of the energy storage system is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0068] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0069] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0070] The present application is described in detail below through specific embodiments:

[0071] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides an energy storage cabinet 100, which includes a cabinet body 110, a non-contact water immersion sensor 120, a supporting bracket 130, a clamping bracket 140 and a fastening assembly 150. The detection head of the non-contact water immersion sensor 120 faces the bottom of the cabinet body 110; the supporting bracket 130 is fixed in the cabinet body 110, and the non-contact water immersion sensor 120 is arranged on the supporting bracket 130 and between the clamping bracket 140; the fastening assembly 150 is used to connect the clamping bracket 140 to the supporting bracket 130, so that the clamping bracket 140 and the supporting bracket 130 clamp the non-contact water immersion sensor 120.

[0072] The supporting bracket 130 and the holding bracket 140 include but are not limited to a frame structure, a box structure, etc. The bottom of the cabinet 110 refers to a position located at the bottom in the height direction of the cabinet 110, wherein the height direction of the cabinet 110 refers to Figure 1 The bottom of the cabinet is the direction indicated by the arrow Z. Figure 1 The position indicated by the arrow in A1.

[0073] The above-mentioned non-contact water immersion sensor 120 can detect whether water has entered the bottom of the cabinet 110. The detection principle is to use the refractive index and reflectivity of the emitted light in different media for detection. Specifically, if the bottom wall of the cabinet 110 is not filled with water, the emitted light of the detection head of the non-contact water immersion sensor 120 is reflected by the bottom of the cabinet 110 and can be received by the detection head. Because the reflectivity and refractive index of water are different from those of the bottom of the cabinet 110, if water enters the bottom wall of the cabinet 110, the emitted light of the detection head of the non-contact water immersion sensor 120 will not be received by the detection head after reflection.

[0074] Since the detection head of the non-contact water immersion sensor 120 is facing the bottom of the cabinet 110, the non-contact water immersion sensor 120 can detect whether water has entered the bottom of the cabinet 110. Since the supporting bracket 130 is fixed in the cabinet 110, the non-contact water immersion sensor 120 is arranged on the supporting bracket 130 and between the clamping bracket 140, and the fastening component 150 is used to connect the clamping bracket 140 to the supporting bracket 130. On the one hand, the non-contact water immersion sensor 120 can be fixed in the cabinet 110 by the supporting bracket 130 and the clamping bracket 140, thereby avoiding the non-contact water immersion sensor 120 from moving when the cabinet 110 moves. On the other hand, when installing the non-contact water immersion sensor 120, the non-contact water immersion sensor 120 is first located between the supporting bracket 130 and the clamping bracket 140, and then the fastening assembly 150 connects the clamping bracket 140 to the supporting bracket 130. In this way, the distance between the supporting bracket 130 and the clamping bracket 140 can be appropriately adjusted according to the specifications of the non-contact water immersion sensor 120, thereby facilitating the fixed installation of the non-contact water immersion sensor 120 and being suitable for the fixation of non-contact water immersion sensors 120 of various specifications.

[0075] In addition, compared with the solution of using a water immersion detection rope to detect whether water has entered the bottom of the cabinet 110, fixing the non-contact water immersion sensor 120 in the cabinet 110 by the supporting bracket 130 and the clamping bracket 140 can ensure the cleanliness of the cabinet 110.

[0076] In some possible embodiments, see Figure 3 and Figure 4The supporting bracket 130 is provided with a first clamping portion 131 and a plurality of first connecting portions 132, and the plurality of first connecting portions 132 are respectively located on two opposite sides of the first clamping portion 131; the clamping bracket 140 is provided with a second clamping portion 141 and a plurality of second connecting portions 142, and the plurality of second connecting portions 142 are respectively located on two opposite sides of the second clamping portion 141, and the plurality of second connecting portions 142 correspond one-to-one to the plurality of first connecting portions 132, and a portion of the non-contact water immersion sensor 120 is located between the first clamping portion 131 and the second clamping portion 141; the fastening assembly 150 includes a plurality of fasteners 151, and the plurality of fasteners 151 correspond one-to-one to the plurality of first connecting portions 132, and each fastener 151 connects a second connecting portion 142 and a corresponding first connecting portion 132, so that the first clamping portion 131 and the second clamping portion 141 clamp the non-contact water immersion sensor 120.

[0077] Since the plurality of first connection parts 132 are respectively located on the opposite sides of the first clamping part 131, and the plurality of second connection parts 142 are respectively located on the opposite sides of the second clamping part 141, part of the non-contact water immersion sensor 120 is located between the first clamping part 131 and the second clamping part 141, and each fastener 151 connects a second connection part 142 and a corresponding first connection part 132, the non-contact water immersion sensor 120 can be fastened on the opposite sides, thereby improving the effect of fastening the non-contact water immersion sensor 120.

[0078] In addition, by providing multiple first connection parts 132, multiple second connection parts 142 and multiple fasteners 151, and the multiple first connection parts 132 correspond one-to-one with the multiple second connection parts 142 and the multiple fasteners 151 respectively, multiple fastening points can be provided to ensure the fastening effect of the non-contact water immersion sensor 120.

[0079] In addition, the above-mentioned multiple refers to a number of two or more.

[0080] For example, the first connection part 132 and the second connection part 142 each include two, the two first connection parts 132 are respectively located on the opposite sides of the first clamping part 131, and the two second connection parts 142 are respectively located on the opposite sides of the second clamping part 141, and the fastening assembly 150 includes two fasteners 151, one of the two fasteners 151 connects a first connection part 132 and the corresponding second connection part 142, and the other connects the remaining first connection part 132 and the corresponding second connection part 142.

[0081] In some possible embodiments, see Figure 3 and Figure 4, the shape of the clamping surface of the first clamping portion 131 matches the outer contour of the non-contact water immersion sensor 120 ; and / or, the shape of the clamping surface of the second clamping portion 141 matches the outer contour of the non-contact water immersion sensor 120 .

[0082] The embracing surfaces of the first embracing portion 131 and the second embracing portion 141 both refer to the surfaces in contact with the non-contact water immersion sensor 120 .

[0083] In addition, the shape of the above-mentioned clamping surface matches the outer contour of the non-contact water immersion sensor 120. It should be understood that if the outer contour of the non-contact water immersion sensor 120 is cylindrical, then the corresponding clamping surface is an arc surface. If the outer contour of the non-contact water immersion sensor 120 is a quadrangular prism, then the corresponding clamping surface is a plane or two planes that are connected and perpendicular to each other.

[0084] Therefore, by matching the shape of the clamping surface of the first clamping portion 131 with the outer contour of the non-contact water immersion sensor 120, the contact area between the first clamping portion 131 and the non-contact water immersion sensor 120 can be increased. Similarly, by matching the shape of the clamping surface of the second clamping portion 141 with the outer contour of the non-contact water immersion sensor 120, the contact area between the second clamping portion 141 and the non-contact water immersion sensor 120 can be increased, thereby improving the fixing effect of the supporting bracket 130 and the clamping bracket 140 on the non-contact water immersion sensor 120.

[0085] In some possible embodiments, see Figure 3 and Figure 4 The energy storage cabinet 100 also includes a control module; the non-contact water immersion sensor 120 includes a conical detection head 121 and a cylindrical body 122 that are connected to each other, the conical detection head 121 is located in the installation space formed by the supporting bracket 130 and the clamping bracket 140, the cylindrical body 122 is located between the first clamping part 131 and the second clamping part 141, and a feedback component that is communicatively connected to the conical detection head 121 is arranged in the cylindrical body 122, and the feedback component is communicatively connected to the control module.

[0086] A battery is disposed in the energy storage cabinet 100 , and the non-contact water immersion sensor 120 is electrically connected to the battery.

[0087] The feedback component is communicatively connected to the control module. It should be understood that the feedback component and the control module are communicatively connected via a signal line, or the feedback component and the control module are communicatively connected via a wireless signal.

[0088] Specifically, when the non-contact water immersion sensor 120 detects whether water has entered the bottom of the cabinet 110, it first emits light to the bottom of the cabinet 110 through the conical detection head 121. If water has entered the bottom of the cabinet 110, the reflected light cannot be received. In this case, the feedback component transmits the signal that the reflected light has not been received to the control module to control an alarm such as a warning light or an alarm to be activated to indicate that water has entered the bottom of the cabinet 110. Otherwise, the alarm will not be activated.

[0089] The feedback component may be a reflection signal receiver, a signal processor, etc.

[0090] In addition, since the conical detection head 121 is located in the installation space formed by the supporting bracket 130 and the clamping bracket 140, and the cylindrical body 122 is located between the first clamping portion 131 and the second clamping portion 141, on the one hand, since the outer diameters of the cylindrical body 122 are the same, the design of the first clamping portion 131 and the second clamping portion 141 is simplified, and at the same time, the connection stability between the first clamping portion 131 and the second clamping portion 141 and the cylindrical body 122 is guaranteed. On the other hand, since the conical detection head 121 is located in the installation space formed by the supporting bracket 130 and the clamping bracket 140, the larger part of the structure of the non-contact water immersion sensor 120 is located in the installation space, thereby further improving the stability of the non-contact water immersion sensor 120 fixed in the cabinet 110.

[0091] In some possible embodiments, see Figure 5 , Figure 6 and Figure 7 A first connecting through hole 1321 is provided on the first connecting portion 132, and a second connecting through hole 1421 is provided on the second connecting portion 142; the fastener 151 includes a bolt 1511 and a nut 1512 matched with the bolt 1511, the bolt 1511 includes a bolt head 15111 and a screw rod 15112 connected to each other, the screw rod 15112 is passed through the first connecting through hole 1321 and the corresponding second connecting through hole 1421, and the nut 1512 is tightened on a section of the screw rod 15112 away from the bolt head 15111.

[0092] Since the bolts 1511 and the nuts 1512 can be purchased directly and are relatively low in cost, fastening the first connecting portion 132 and the second connecting portion 142 by the bolts 1511 and the nuts 1512 can, on the one hand, reduce the cost of fixing the non-contact water immersion sensor 120, and on the other hand, can also simplify the structure for fastening the first connecting portion 132 and the second connecting portion 142.

[0093] Of course, in some other embodiments, the first connection portion 132 and the corresponding second connection portion 142 may be connected in other ways, such as welding, clamping, etc.

[0094] In some possible embodiments, see Figure 7 When the first embracing portion 131 and the second embracing portion 141 embracing the non-contact water immersion sensor 120 , a gap exists between the first connecting portion 132 and the corresponding second connecting portion 142 .

[0095] Since there is a gap between the first connection part 132 and the corresponding second connection part 142 when the first clamping part 131 and the second clamping part 141 clamp the non-contact water immersion sensor 120, on the one hand, when the fastener 151 fastens the first clamping part 131 and the second clamping part 141, the first clamping part 131 and the second clamping part 141 can clamp the non-contact water immersion sensor 120, and on the other hand, the first clamping part 131 and the second clamping part 141 can clamp the non-contact water immersion sensors 120 of different specifications, thereby improving the applicability of the supporting bracket 130 and the clamping bracket 140 for fixing the supporting bracket 130 and the clamping bracket 140.

[0096] In some possible embodiments, see Figure 7 and Figure 8 The fastening assembly 150 is connected to the top of the load-bearing bracket 130 and the top of the clamping bracket 140 ; ​​the energy storage cabinet 100 also includes a connecting member 160 , which is connected to the side wall of the load-bearing bracket 130 and the side wall of the clamping bracket 140 .

[0097] The connecting member 160 may be a screw, a limiting column or the like.

[0098] Since the fastening assembly 150 is connected to the top of the supporting bracket 130 and the top of the clamping bracket 140 , in order to improve the stability of the clamping bracket 140 relative to the supporting bracket 130 , the connecting member 160 is connected to the side wall of the supporting bracket 130 and the side wall of the clamping bracket 140 .

[0099] In some possible embodiments, see Figure 8 A waist-shaped hole 143 is provided on the side wall of the clamping bracket 140, and the length direction of the waist-shaped hole 143 is parallel to the clamping direction of the clamping bracket 140 and the supporting bracket 130; a connecting hole 133 is provided on the side wall of the supporting bracket 130, and one end of the connecting piece 160 passes through the waist-shaped hole 143 and is connected to the connecting hole 133.

[0100] The clamping direction of the clamping bracket 140 and the supporting bracket 130 is Figure 8 The direction indicated by the X arrow.

[0101] Specifically, when the connecting member 160 is a screw, the connecting hole 133 is a threaded hole, and the connecting member 160 passes through the waist-shaped hole 143 and is threadedly connected to the connecting hole 133; when the connecting member 160 is a limiting rod, the connecting hole 133 is a smooth hole, and the connecting member 160 passes through the waist-shaped hole 143 and is interference fit with the connecting hole 133.

[0102] Therefore, by providing the waist-shaped hole 143 on the side wall of the clamping bracket 140 , when the clamping bracket 140 is connected to the supporting bracket 130 , the installation accuracy of the clamping bracket 140 on the supporting bracket 130 can be reduced.

[0103] In some possible embodiments, see Figure 8 The supporting bracket 130 has a first side wall 134 and a second side wall 135 opposite to each other, the connecting hole 133 is located on the first side wall 134, and a snap-in groove 1351 is provided on the second side wall 135; a snap-in protrusion 144 is provided on the top of the clamping bracket 140, and the snap-in protrusion 144 cooperates with the snap-in groove 1351.

[0104] Since the connecting hole 133 is located on the first side wall 134, when the connecting piece 160 passes through the waist-shaped hole 143 and is connected to the connecting hole 133, the first side wall 134 of the supporting bracket 130 can be fixedly connected to the clamping bracket 140. In addition, since a snap-in groove 1351 is provided on the second side wall 135 and a snap-in protrusion 144 is provided on the top of the clamping bracket 140, the snap-in protrusion 144 cooperates with the snap-in groove 1351, so the second side wall 135 of the supporting bracket 130 is fixedly connected to the clamping bracket 140, thereby further improving the stability of the clamping bracket 140 and the supporting bracket 130 in clamping the non-contact water immersion sensor 120.

[0105] In some possible embodiments, see Figure 8 The second side wall 135 is also provided with a mounting portion 136 , and the mounting portion 136 is used to be connected to the inner wall of the cabinet 110 .

[0106] Specifically, a mounting portion 136 such as a mounting hole or a mounting hook is provided on the second side wall 135 , and the mounting portion 136 is mounted on the inner wall of the cabinet 110 by using screws or connecting protrusions.

[0107] Since the mounting portion 136 is connected to the inner wall of the cabinet 110 , the supporting bracket 130 can be fixed on the inner wall of the cabinet 110 , and the structure is simple and easy to install.

[0108] In some possible embodiments, see Fig. 9 , there is a light-transmitting hole 137 on the bottom wall of the supporting bracket 130 , and the light-emitting surface of the non-contact water immersion sensor 120 faces the light-transmitting hole 137 .

[0109] Since the light-emitting surface of the non-contact water immersion sensor 120 is opposite to the light-transmitting hole 137, the outgoing light of the non-contact water immersion sensor 120 can be emitted to the bottom of the cabinet 110 through the light-transmitting hole 137, and the reflected light can pass through the light-transmitting hole 137. If there is no water ingress at the bottom of the cabinet 110, the reflected light can be received by the non-contact water immersion sensor 120. Otherwise, the reflected light cannot be received, thereby obtaining a detection result of whether water has entered the bottom of the cabinet 110.

[0110] In some possible embodiments, see Fig.10 The distance between the light emitting surface of the non-contact water immersion sensor 120 and the bottom of the cabinet 110 is d, 2mm≤d≤4mm.

[0111] The light emitting surface is Fig.10 The position indicated by arrow A2 is the bottom of the cabinet 110. Fig.10 The position indicated by the arrow in A1.

[0112] If the distance between the light-emitting surface of the non-contact water immersion sensor 120 and the bottom of the cabinet 110 is less than 2 mm, then when water enters the bottom of the cabinet 110, the non-contact water immersion sensor 120 is very easy to be soaked by the water, thereby affecting the service life of the non-contact water immersion sensor 120; if the distance between the light-emitting surface of the non-contact water immersion sensor 120 and the bottom of the cabinet 110 is greater than 4 mm, then the distance between the bottom of the cabinet 110 and the detection head of the non-contact water immersion sensor 120 is too large, thereby affecting the detection accuracy of the non-contact water immersion sensor 120; therefore, when the distance between the light-emitting surface of the non-contact water immersion sensor 120 and the bottom of the cabinet 110 is between 2 mm and 4 mm, both the service life and the detection accuracy of the non-contact water immersion sensor 120 can be guaranteed.

When the power grid is powered off or there is a power outage, the energy storage cabinet 100 supplies power to the household appliances and street lights.

[0115] In addition, the electric energy conversion device 210 can convert at least one of solar energy, light energy, wind energy, thermal energy, tidal energy, biomass energy and mechanical energy into electric energy.
