Description

Technical Field

[0001] This application relates to the field of control equipment technology, specifically to a central control box. Background Technology

[0002] A control box is a device with control functions. It includes electronic components such as a processor. The control box receives instructions, processes them, and then sends out control signals to control external devices (such as motors, valves, lights, machines, etc.) to perform corresponding operations.

[0003] The control box consists of a housing and a power cord. The power cord passes through the housing and is electrically connected to the power module inside the housing. There are gaps at the connection between the power cord and the housing. If dust or moisture enters the control box through these gaps, it will increase the risk of malfunctions or even short circuits in the internal electronic components.

[0004] Currently, sealant is commonly used to seal the gaps between the power cord and the enclosure. However, sealant is susceptible to aging and failure due to environmental factors. When sealant fails, the old sealant must be cleaned up before refilling the gaps. But if residual sealant is not thoroughly cleaned from the enclosure and / or power cord, the particles and oxide layer of the old sealant will directly affect the bonding strength and sealing effect of the new sealant. Furthermore, once the sealant has cured, it adheres to the power cord and enclosure, making it difficult to clean completely and increasing maintenance time and costs.

[0005] How to seal the gap between the power cord and the enclosure, and reduce the time cost of subsequent sealing repairs, is an urgent problem to be solved. Utility Model Content

[0020] In one possible implementation, a cover plate is detachably provided on the housing, the cover plate being used to close the opening of the housing;

[0021] The inner wall of the opening is provided with a support platform for supporting the cover plate, and the support platform is arranged circumferentially along the inner wall of the opening; a sealing ring is provided on the support surface of the support platform, and the sealing ring is used to seal the gap between the support platform and the cover plate.

[0022] In one possible implementation, the outer end face of the cover plate is provided with legs and supports, wherein there are two supports arranged symmetrically;

[0023] The bottom surface of the outrigger and the bottom surface of the support are located on the same plane;

[0024] The cover plate is provided with a cavity, and a waterproof and breathable valve is installed in the cavity.

[0025] In one possible implementation, the support includes a main body and connecting arms, with two connecting arms positioned on either side of the main body; wherein the connecting arms are fixedly connected to the outer end face of the cover plate, and the main body is spaced apart from the outer end face of the cover plate;

[0054] Example

[0055] See Figure 1 and Figure 2 In this embodiment, a central control box is proposed, including a housing 100, a sealing joint 200, and a power cord 300.

[0056] like Figure 3 As shown, the housing 100 is provided with a mounting hole 110, and the sealing joint 200 is sealed and inserted into the mounting hole 110.

[0057] The sealing joint 200 can be made of an elastic material, such as rubber or silicone.

[0058] like Figures 4-6 As shown, the sealing joint 200 includes a first sealing part 210 and a second sealing part 220, wherein a cylindrical connecting part 230 is provided between the first sealing part 210 and the second sealing part 220. After the sealing joint 200 is assembled with the mounting hole 110, the first sealing part 210 and the second sealing part 220 are tightly fitted to the outer surface and inner surface of the housing 100, respectively, and the outer wall of the connecting part 230 is tightly fitted to the inner wall of the mounting hole 110, thereby achieving the sealing of the mounting hole 110 by the sealing joint 200.

[0059] The sealing connector 200 includes a wire hole 240, into which the power cord 300 can be detachably inserted.

[0060] A sealing element 241 is provided inside the wire hole 240. The sealing element 241 is sleeved on the power cord 300 and makes sealing contact with the power cord 300. The sealing element 241 includes a sealing ring, which can be fitted into the mounting groove inside the wire hole 240.

[0061] Since the power cord 300 can be detachably inserted into the wire hole 240 of the sealing connector 200, when the sealing connector 200 or the seal 241 inside the sealing connector 200 ages and fails, the user can easily separate the sealing connector 200 from the power cord 300 to replace the sealing connector 200 or the seal 241, thereby effectively reducing the time cost of maintenance.

[0062] When the central control box is in use (e.g., during the process of moving the central control box, plugging and unplugging the power cord 300, winding the power cord 300, etc.), the power cord 300 may be subjected to tension due to its own weight or external force. If the power cord 300 is displaced relative to the sealing joint 200 due to the tension, it may affect the sealing performance between the power cord 300 and the sealing joint 200.

[0063] like Figure 7 and Figure 8 As shown, a wire clamp 120 is provided inside the housing 100. The wire clamp 120 is used to clamp the power cord 300 to secure the portion of the power cord 300 located inside the housing 100. Only a portion of the power cord 300 inside the housing 100 is shown.

[0064] When the power cord 300 is under tension, the clamp 120 keeps the power cord 300 and the sealing joint 200 relatively fixed, preventing gaps from forming due to loose connection and effectively improving the reliability of the seal between the power cord 300 and the sealing joint 200. Furthermore, since the portion of the power cord 300 inside the housing 100 is fixed by the clamp 120, it will not move when under tension. This ensures the stability of the connection between the power cord 300 and the electronic components inside the housing 100, preventing loosening or disconnection of the connection.

[0065] like Figure 9 and Figure 10 As shown, the wire clamp 120 includes a clamp body 130.

[0066] The clamp 130 is provided with a U-shaped wire groove 131. The wire groove 131 includes an open end 132 and a closed end 133 arranged opposite to each other. The inner wall of the closed end 133 is provided with an abutment protrusion 134, which is used to abut against the outer surface of the power cord 300, thereby increasing the clamping force on the power cord 300.

[0067] The clamp 130 includes a first presser foot 135 and a second presser foot 136, which are respectively located on both sides of the open end 132.

[0068] Furthermore, the wire clamp 120 also includes a base 140, which includes a closing portion 141, a first end portion 142, and a second end portion 143, with the first end portion 142 and the second end portion 143 respectively located at both ends of the closing portion 141. The closing portion 141, the first end portion 142, and the second end portion 143 are an integral structure. Figure 9 The dotted lines in the text do not exist in the actual product; they are only used to distinguish the closed part 141, the first end 142, and the second end 143.

[0069] The closure portion 141 is used to close the opening end 132 and abuts against the outer surface of the power cord 300. The first end 142 is used to abut against the first pressure foot 135, and the second end 143 is used to abut against the second pressure foot 136.

[0070] In this embodiment, the power cord 300 is clamped by the wire clamp 120 through the combined action of the abutment protrusion 134 and the closure portion 141. Testing showed that when the power cord 300 is subjected to a pulling force of at least 10 kg, the power cord 300 remains relatively fixed to the wire clamp 120.

[0071] like Figure 3 and Figure 8 As shown, a first support frame 151 and a second support frame 152 are provided inside the housing 100. The first support frame 151 is used to support the first end 142, and the second support frame 152 is used to support the second end 143.

[0072] The first end 142 is located between the first pressure foot 135 and the first support frame 151, wherein the first pressure foot 135, the first end 142, and the first support frame 151 are fixedly connected by screws. The second end 143 is located between the second pressure foot 136 and the second support frame 152, wherein the second pressure foot 136, the second end 143, and the second support frame 152 are fixedly connected by screws. This achieves relative fixation between the wire clamp 120 and the housing 100, and also ensures that the power cord 300 is clamped by the wire clamp 120.

[0073] like Figure 2 As shown, a cover plate 160 is detachably provided at the bottom of the housing 100, and the cover plate 160 is used to close the opening of the housing 100.

[0074] like Figure 12 As shown, the inner wall of the opening is provided with a support platform 170 for supporting the cover plate 160, and the support platform 170 is arranged circumferentially along the inner wall of the opening. A sealing ring is provided on the support surface of the support platform 170, and the sealing ring is used to seal the gap between the support platform 170 and the cover plate 160.

[0075] The sealing ring is placed on the support surface beforehand, and then the cover plate 160 is placed on the opening. The cover plate 160 is fixed to the housing 100 by means of screws or other methods. The sealing ring is pressed between the support platform 170 and the cover plate 160, thereby achieving a sealing effect.

[0076] like Figure 2 As shown, the outer end face of the cover plate 160 is provided with a support leg 161 and a support 162, wherein there are two supports 162 arranged symmetrically.

[0077] The bottom surfaces of the outrigger 161 and the support 162 are on the same plane. Thus, when the cover plate 160 is placed on a horizontal surface, the bottom surfaces of both the outrigger 161 and the support 162 can contact the surface, thereby ensuring the stability of the central control box when it is placed.

[0078] A recess is provided on the cover plate 160, and a waterproof and breathable valve 163 is installed inside the recess.

[0079] The waterproof and breathable valve 163 prevents water or external contaminants from entering the enclosure, ensuring the safe and stable operation of the central control box. In addition, the waterproof and breathable valve 163 also serves to provide internal and external ventilation and heat dissipation, and to balance internal and external pressure. The specific structure of the waterproof and breathable valve 163 can be referenced from existing designs and will not be elaborated upon here.

[0080] like Figure 2 As shown, the support 162 includes a main body 1621 and connecting arms 1622. There are two connecting arms 1622, which are located on both sides of the main body 1621. The connecting arms 1622 are fixedly connected to the outer end face of the cover plate 160, and the main body 1621 is spaced apart from the outer end face of the cover plate 160. The main body 1621 is provided with a hanging hole 1623, so that it can be hooked with hooks or other structures to realize the suspension of the central control box.

[0081] like Figure 6 As shown, a contact member 242 is provided inside the wire hole 240, which is used to abut against the outer surface of the power cord 300. The contact member 242 and the sealing connector 200 are an integral structure.

[0082] When the power cord 300 is inserted into the wire hole 240, the abutment 242 can abut against the outer surface of the power cord 300, thereby positioning and fixing the power cord 300. When the power cord 300 is subjected to tension, the friction between the abutment 242 and the power cord 300 can prevent the power cord 300 from moving relative to the sealing joint 200, thereby improving the stability of the connection between the power cord 300 and the sealing joint 200 and avoiding the sealing performance being affected by the loosening of the power cord 300 and the sealing joint 200.

[0083] There are two abutment parts 242 and two seal parts 241, which reduces manufacturing costs while ensuring sealing reliability. Each abutment part 242 is located between two seal parts 241, which facilitates the installation and removal of the seal parts 241.

[0084] The abutment 242 includes a plurality of protrusions 2421 arranged in a ring array. Each protrusion 2421 includes an arc-shaped abutment surface, wherein the abutment surface is used to abut and fit against the outer wall surface of the power cord 300.

[0085] like Figure 3 and Figure 11 As shown, a mounting plate 181 and a main control circuit board 182 are provided inside the housing 100. The mounting plate 181 and the main control circuit board 182 are spaced apart. This arrangement can ensure the heat dissipation of the electronic components inside the housing 100.

[0086] Reference Figure 12 A column 184 of corresponding height is set at a corresponding position inside the housing 100, thereby realizing the installation and positioning of the mounting plate 181 and the main control circuit board 182. The mounting plate 181 and the main control circuit board 182 are fixed to the column 184 of corresponding height by means of screw connection, so as to realize the spacing between the mounting plate 181 and the main control circuit board 182.

[0087] A switch converter 183 is disposed on the side of the mounting plate 181 opposite to the main control circuit board 182, thereby further increasing the distance between the switch converter 183 and the main control circuit board 182 and improving the heat dissipation effect. The power supply line 300 is electrically connected to the switch converter 183.

[0088] In some embodiments, the central control box can be used to control the pool wave generator. Specifically, the housing 100 is provided with multiple electrical connectors, all of which are electrically connected to the main control circuit board 182. The multiple electrical connectors can be connected to water level sensors, water pumps, temperature sensors, turbidity sensors, etc., respectively through corresponding signal lines.
