Description

Technical Field

[0001] This utility model relates to rainproof devices, and more particularly to rainproof devices for outdoor refrigeration units. Background Technology

[0002] In the industrial and commercial sectors, outdoor refrigeration units are widely used in various settings, such as cold storage facilities, supermarkets, and factories. These units are typically installed outdoors, on rooftops, or in other open-air locations to ensure good ventilation and heat dissipation. However, due to their long-term exposure to the natural environment, these refrigeration units are inevitably affected by weather conditions, especially rainy weather.

[0003] Existing refrigeration unit casings typically employ leakage-proof designs and utilize corrosion-resistant materials to enhance weather resistance. However, these measures do not completely eliminate the potential hazards of rainwater to refrigeration units. During prolonged rainy weather, water can easily enter the unit's joints and exhaust vents, causing internal components to become damp or accumulate water, leading to a series of problems such as electrical short circuits, mechanical failures, and reduced efficiency. Furthermore, the unit casing, constantly exposed to rainwater, is prone to rust and corrosion, further shortening the equipment's lifespan. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a rainproof device for outdoor refrigeration units.

[0005] The technical solution is as follows: A rainproof device for an outdoor refrigeration unit includes a mounting shell, a front support, and a drive motor. An automatic roller blind is installed at the upper end of the mounting shell. Two first folding arms are hinged to the front end of the mounting shell via a vertical shaft. A second folding arm is hinged to the front end of each of the two first folding arms. A slider is hinged to the front end of each of the two second folding arms. The two sliders are slidably connected to the front support. The free end of the curtain of the automatic roller blind is fixed to the upper end of the front support. When the first and second folding arms are open, the curtain unfolds; when the first and second folding arms are folded, the curtain retracts. The drive motor is driven by the vertical shaft.

[0006] Furthermore, when the curtain of the automatic roller blind is unfolded, it is arranged in an inclined manner with the front lower and the back higher, and the upper surface of the curtain is formed with guide strips running in the front and back direction, so that rainwater is collected at the front end of the curtain along the guide strips.

[0007] Furthermore, the front end of the front support is provided with a water collection trough with an open top, and a drain outlet is opened on the side of the water collection trough.

[0008] Furthermore, a flexible drainage component is provided at the lower end of the drain outlet.

[0009] Furthermore, the drainage component is a thin strip of cloth or a thin rope.

[0010] Furthermore, the top of the front support is provided with a groove with an upper opening. A drainage hole is provided on one side of the groove, which is connected to a water collection tank. An elongated hole is provided on the other side of the groove, which passes through the groove and connects to the outside. A rainwater detection unit and a sealing block are provided in the groove. The sealing block is slidably engaged with the groove to seal and open the drainage hole. An outward protrusion is formed on one side of the sealing block, which passes through the elongated hole and is slidably connected to it. A guide post is provided along the length direction in the elongated hole, and a spring is sleeved on the guide post. The outward protrusion is located on the running path of one of the sliders. When the curtain retracts, the slider drives the sealing block to seal the drainage hole. When the curtain opens, the spring drives the sealing block to open the drainage hole.

[0011] The beneficial effects of this invention are as follows: The rainproof device of this invention adopts a drive motor and an automatic roller shutter system, which can open and close according to external weather conditions. The drive motor is connected via a vertical shaft transmission, precisely controlling the opening and folding of the first and second folding arms. During rainfall, the drive motor starts, the first and second folding arms open, allowing the curtain to unfold and cover the refrigeration unit, effectively blocking rainwater. After the rain stops, the drive motor reverses, the folding arms fold, the curtain retracts, and the refrigeration unit resumes its normal heat dissipation function. This device not only improves protection efficiency but also reduces manual intervention and enhances the intelligence level of the equipment.

[0012] In addition, the inclined arrangement of the curtain with a lower front and a higher back allows rainwater to flow effectively along the guide strips to the front of the curtain, preventing rainwater from stagnating on the curtain and facilitating subsequent drainage treatment, thereby reducing the risk of curtain deformation or damage caused by water accumulation.

[0013] In addition, the water collection tank effectively collects rainwater flowing down from the curtain fabric, preventing rainwater from falling directly around the refrigeration unit and reducing the risk of the equipment getting damp. The drain outlet ensures that rainwater in the collection tank can be discharged in a timely manner.

[0014] In addition, the flexible drainage component makes the drainage process more flexible and adaptable to different drainage needs. This component can effectively guide rainwater to designated drainage areas, preventing rainwater from accumulating around the equipment and reducing the potential risk of water damage.

[0015] In addition, intelligent drainage management is achieved through the rainwater detection unit. When rainwater enters the groove, the water level rises, triggering the rainwater detection unit. At this time, the rainwater detection unit detects the rain and, through signal transmission, controls the drive motor to open the curtain to block the rain. Simultaneously, during the opening process, the slider moves, causing the sealing block to automatically open the drainage hole, ensuring that the rainwater can be discharged smoothly. After the weather clears up, if the rainwater detection unit no longer detects rainwater in the groove, it will control the drive motor again to retract the curtain. Through the above structural design, not only is the automation level of the rainproof device improved, but its adaptability to environmental changes is also enhanced. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Figure 1-3The rainproof device for the outdoor refrigeration unit shown includes a mounting shell 1, a front support 2, and a drive motor 7. An automatic roller blind 3 is installed on the upper end of the mounting shell 1. The front end of the mounting shell 1 is hinged to two first folding arms 4 via a vertical shaft. In this embodiment, the two first folding arms 4 are symmetrically arranged. The front ends of the two first folding arms 4 are respectively hinged to second folding arms 5, and the front ends of the two second folding arms 5 are respectively hinged to sliders 6. The two sliders 6 are slidably connected to the front support 2. In this embodiment, the front support 2 is provided with transverse sliding grooves adapted to the two sliders 6. The free end of the curtain 31 of the automatic roller blind 3 is fixed to the upper end of the front support 2 by rivets. When the first folding arms 4 and the second folding arms 5 are opened, the curtain 31 is in the unfolded state, which can protect the refrigeration unit a from rain, effectively preventing rainwater from entering the joints and heat exhaust holes of the refrigeration unit a, avoiding moisture and water accumulation in the internal components, and improving the stability and reliability of the unit operation. When the first folding arm 4 and the second folding arm 5 are folded, the curtain 31 is in a retracted state; the drive motor 7 is connected to the vertical shaft transmission, and the drive motor 7 drives the opening and folding of the first folding arm 4 and the second folding arm 5 through the vertical shaft.

[0024] refer to Figure 4 In one specific embodiment, the vertical axis includes two sets of first shafts 71 and second shafts 72 that extend vertically through the bottom of the mounting housing 1. Taking one set as an example, the rear end of one of the first folding arms 4 is fixedly connected to the second shaft 72 by a key. The drive motor 7 is connected to the first shaft 71 for transmission. A gear 73 is provided at the lower end of the first shaft 71 and the second shaft 72 respectively. The two gears 73 mesh, and the drive motor 7 drives the second shaft 72 to rotate through the meshing of the gears 73. The second shaft 72 then drives the first folding arm to move. During the opening process of the first folding arm 4 and the second folding arm 5, they rotate around the hinge point between the second shaft 72 and the second folding arm 5 and the slider 6, respectively. When the connection point moves outward, the included angle between the two folding arms increases. When they fold, they move in opposite directions, which can cause the areas of the two folding arms to overlap. To further reduce the volume after folding, a receiving compartment is provided on the front side of the mounting housing 1 to accommodate the first folding arm 4 and the second folding arm 5 in the folded state.

[0025] In a preferred embodiment, the curtain 31 of the automatic roller blind 3 is arranged in an inclined manner with the front lower and the back higher when it is unfolded. A guide strip 32 with a front-to-back direction is formed on the upper surface of the curtain 31, and rainwater is collected along the guide strip 32 to the front end of the curtain 31.

[0026] Furthermore, a water collection trough 21 with an open top is provided at the front end of the front support 2, and a drain outlet 22 is opened on the side of the water collection trough 21. Rainwater flows into the water collection trough 21 along the front end of the curtain 31 and then is discharged through the drain outlet 22. This concentrates the drainage point, reducing raindrop splashing and preventing dampness and adhesion around the refrigeration unit. As a further preferred embodiment, a flexible drainage component 8 is provided at the lower end of the drain outlet 22. The flexible drainage component 8 makes the drainage process more flexible and effectively guides rainwater to the designated drainage area. In particular, the drainage component 8 is made of thin cloth strips or thin ropes. The use of this material is not only lightweight but also easy to install and replace, further improving the maintenance convenience and economy of the rainproof device.

[0027] Furthermore, this device is also designed with an automatic opening and closing mechanism, which selects whether to activate the rain-proof function based on whether it is raining or the rain has stopped. Figure 5 As shown, it specifically includes:

[0028] The front support 2 has a groove 23 with an opening at the top. A drainage hole 24 is located on one side of the groove 23, communicating with a water collection tank 21. An elongated hole 25 is located on the other side of the groove 23, penetrating the groove 23 and communicating with the outside. The length of the elongated hole 25 is parallel to the movement direction of the slider 6. A rainwater detection unit 9 and a sealing block 10 are installed inside the groove 23. The sealing block 10 slides within the groove 23, allowing it to block and open the drainage hole 24. A protruding portion 11 is formed on one side of the sealing block 10, penetrating and slidingly connecting with the elongated hole 25. A guide post 12 is installed along the length of the elongated hole 25, and a spring 13 is fitted onto the guide post 12. One end of the spring 13 abuts against... The side of the protruding part 11 of the sealing block 10 abuts against the side of the elongated hole 25. When there is no external force, the spring 13 acts on the protruding part 11 of the sealing block 10, causing the sealing block 10 to misalign with the drain hole 24, thereby opening the drain hole 24 for drainage. The protruding part 11 is located on the running path of one of the adjacent sliders 6. When the curtain 31 retracts, the first folding arm 4 and the second folding arm 5 drive the slider 6 to move forward towards the end of the support 2. When the slider 6 touches the protruding part 11, it drives the sealing block 10 to block the drain outlet 22. If it rains at this time, rainwater will accumulate in the groove 23. The rainwater detection unit 9 will then detect the rain and send a rain-shielding signal to activate the curtain 31. The rainwater detection unit 9 integrates a rain sensor module, a humidity sensor module, and a signal transmission module, which can detect the amount of rainwater and humidity in the groove 23 in real time.

[0029] When rain protection is needed, the curtain 31 opens. At this time, the slider 6 no longer acts on the blocking block 10, and the blocking block 10 moves in the opposite direction under the action of the spring 13, causing the drain hole 24 to open. Water in the groove 23 is discharged into the water collection tank 21. Due to continuous rainfall, the water in the water collection tank 21 may not drain in time, causing rainwater to backflow from the water collection tank 21 into the groove 23. Therefore, during rainfall, the rain detection unit 9 can continuously detect rainfall signals. When the rainfall stops, the water in the groove 23 is drained, and the rain detection unit 9 does not detect rainwater for a period of time. It will then send a stop-rain signal, causing the curtain 31 to retract.

[0030] It is particularly important to note that the control unit of this device uses a PLC controller. The PLC controller is electrically or wirelessly connected to the drive motor 7 and the rainwater detection unit 9. The PLC controller integrates a control module, a receiving module, a calculation module, and a transmitting module. The receiving module receives the signals sent by the rainwater detection unit 9, analyzes them through the calculation module, and finally sends instructions to the drive motor 7 through the transmitting module to control the forward and reverse rotation and start and stop of the drive motor 7. The PLC controller is a mature existing technology and will not be described in detail here.

[0031] Additionally, it should be noted that the optimal installation height for this rainproof device should meet the following condition: more than 1.5 meters above the refrigeration unit.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
