Description

Technical Field

[0001] The invention belongs to the technical field of outdoor power equipment, and in particular relates to a top structure of outdoor equipment. Background Art

[0002] With the parity of photovoltaic power generation, the price of photovoltaic inverters is getting lower and lower, and the market competition is becoming more and more fierce. In the design of inverters, outdoor inverters are increasingly favored by inverter manufacturers and EPC contractors due to their relatively low price cost, relatively small footprint, and increasing power density. With the continuous updating and improvement of dust and waterproof measures of outdoor inverters, they are gradually becoming the main products promoted by photovoltaic inverter manufacturers.

[0003] In the design of outdoor inverters, due to the strict requirements of production and project sites for the transportation of outdoor inverters, both forklift transportation and crane transportation must be met, which requires the design of outdoor inverters to meet the transportation requirements of various occasions. At present, the outdoor inverters of various manufacturers can meet the transportation requirements of forklifts, but some manufacturers do not have designs for hoisting transportation, and some manufacturers have designs, but the structure is relatively complex. At present, there are mainly the following solutions for the transportation of outdoor inverters on the market.

[0004] (1) Considering the waterproof requirements on the top of the outdoor inverter, there is no lifting device on the top, so it can only be transported by forklift;

[0005] (2) While meeting the requirements of forklift transportation, a cap is added to the top of the outdoor inverter, and the lifting parts are placed inside the cap. After the whole is welded, it is connected to the cabinet frame with bolts, which can realize forklift transportation and lifting transportation.

[0006] The above two design solutions have the following problems.

[0007] (1) Considering the waterproof requirements on the top of the outdoor inverter, there is no lifting beam on the top or the lifting position can meet the transportation requirements of forklifts, but it cannot meet the transportation requirements of lifting under various complex conditions in ports and project sites;

[0008] (2) Although adding a top cover on the top of the outdoor inverter can meet the requirements of outdoor inverter hoisting, the added top cover needs to bear the weight of the entire inverter, so the added top cover needs to have sufficient bearing capacity, resulting in the cost of adding an additional hat being relatively high, and the seal between the top cover and the inverter frame must meet the waterproof requirements of the top. Summary of the invention

[0009] In order to overcome the problems existing in the prior art, the present invention provides a top structure of outdoor equipment which is easy to hoist and has good waterproof effect, and can meet the hoisting and waterproof requirements at the same time.

[0010] To achieve the above-mentioned purpose, the top structure of an outdoor equipment described in the present invention includes a hanging piece, a top cover and a lifting eye bolt. The top cover is fixed on the frame of the outdoor equipment. The top cover includes a top cover body. A plurality of waterproof rings are fixed on the top cover body. The upper part of the hanging piece has a threaded hole and a first step surface. The upper part of the hanging piece is inserted into the waterproof ring, and the upper end surface of the hanging piece is lower than the upper end surface of the waterproof ring. The upper end surface of the hanging piece and the upper end surface of the waterproof ring form a step structure. A sealing gasket is arranged on the step structure. The first step surface is connected to the lower end surface of the waterproof ring. A sealing strip is arranged at the connection. The lower part of the hanging piece is fixedly connected to the frame. The bolt part of the lifting eye bolt is threadedly connected to the threaded hole of the hanging piece.

[0011] Furthermore, a body reinforcement rib is fixed to the upper portion of the top cover body.

[0012] Furthermore, thermal insulation cotton is fixed on the top cover body.

[0013] Furthermore, a frame reinforcement rib is fixed to the lower end surface of the top cover body, and the frame reinforcement rib and the frame are fixedly connected by fasteners.

[0014] Furthermore, the frame includes a plurality of vertical beams and a bearing frame fixed on the top of the vertical beams, and the frame is divided into an upper part and a lower part by the inverter top plate.

[0015] Furthermore, the upper part of the vertical beam has a first bending edge and a second bending edge which are perpendicular to each other, and the hanging component is welded to the first bending edge, the second bending edge and the top plate.

[0016] Furthermore, a rainproof edge is arranged on the top cover.

[0017] Furthermore, the hanging part is composed of multiple sections of cylinders with different diameters which are fixedly connected in sequence, a threaded hole is opened on the uppermost cylinder, and a first step surface is provided between the uppermost cylinder and the cylinder connected thereto.

[0018] Furthermore, the eye bolt includes a eye and a bolt portion, the bolt portion is fixed to the lower portion of the eye, the bolt portion includes a head fixed to the eye and a threaded portion having threads, and a second step surface is formed between the head and the threaded portion.

[0019] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0020] The solution described in this patent, while ensuring that the outdoor inverter meets the requirements of hoisting and transportation, proposes an outdoor inverter hoisting part and top cover structure with simple structure, convenient installation, lower cost and better waterproof performance. This hoisting part cooperates with the eyebolt and the top cover. Under the premise of meeting the design strength requirements, the outdoor inverter can meet the requirements of hoisting and transportation while meeting the requirements of forklift transportation, which greatly improves the waterproof performance and cost reduction space of the whole machine. When the bolt part of the eyebolt is connected with the threaded hole of the hoisting part, the sealing gasket is squeezed to make the eyebolt and the hoisting part sealed, and the sealing strip provided at the connection between the first step surface and the waterproof ring ensures the sealing between the frame and the top cover, the waterproof ring and the hoisting part, and has good waterproof performance. And when hoisting, the lifting force is applied to the frame through the eyebolt, so the top cover does not need to bear the gravity of the outdoor equipment, and there is no need to increase its bearing capacity, which makes the top cover structure simpler, more convenient to install, and lower in cost.

[0021] Furthermore, thermal insulation cotton is fixed on the top cover body, and the main function of the thermal insulation cotton is to insulate heat and prevent the outdoor equipment from being overheated due to direct sunlight.

[0022] Furthermore, a frame reinforcement rib is fixed to the lower end surface of the top cover body, and the frame reinforcement rib is fixedly connected to the frame by fasteners. The frame reinforcement ribs around are used to prevent the top cover body from warping.

[0023] Furthermore, the frame includes a plurality of vertical beams and a bearing frame fixed on the top of the vertical beams. The frame is divided into an upper part and a lower part by the inverter top plate. The lower part is used for installing the inverter, and the upper part is used for ventilation and heat dissipation.

[0024] Furthermore, the upper part of the vertical beam has a first bending edge and a second bending edge which are perpendicular to each other, and the hanging component is welded to the first bending edge, the second bending edge and the top plate to enhance the strength of the connection between the hanging component and the frame.

[0025] Furthermore, a rainproof edge is arranged on the top cover to cause backflow of rainwater and prevent water accumulation on the top cover. BRIEF DESCRIPTION OF THE DRAWINGS
