Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a precast concrete energy storage compartment. Background Technology

[0002] With the rapid development of the new energy industry, energy storage systems, as key supporting facilities, are being used more and more widely. To adapt to various outdoor environments, energy storage equipment is usually integrated and installed in prefabricated cabins. Among them, a type of prefabricated concrete energy storage cabin has become an important solution due to its advantages such as robust structure, good fire resistance, and long service life.

[0003] Conventional precast concrete energy storage pods mainly consist of the pod body and access doors for personnel entry and exit as well as equipment installation. Because these pods need to be deployed outdoors for extended periods, they inevitably have to withstand harsh natural environments such as wind, rain, and sandstorms. The energy storage equipment inside the pod, such as battery packs and converters, are high-precision electronic and electrical devices, requiring extremely high levels of cleanliness and dryness in their operating environment.

[0004] However, existing precast concrete energy storage pods have significant weaknesses in structural protection, particularly in the sealing design of the entrance and exit doors. Currently, most precast pods use only simple rubber sealing strips for their entrance and exit doors, achieving a passive seal through the pressure generated when the door is closed. This sealing method can provide some protection in the early stages of use.

[0005] However, with prolonged use, simple rubber sealing strips age and deform due to repeated opening and closing, exposure to sun and rain, resulting in decreased elasticity and significantly reduced sealing performance. During heavy rain or strong winds, rainwater can easily seep into the compartment through the aging door gaps under wind pressure, directly threatening the safety of internal equipment. In severe cases, this can lead to short circuits, damage, and major safety accidents and economic losses. This passive and simplistic sealing structure lacks long-term reliability and cannot meet the stringent environmental requirements of energy storage devices.

[0006] Therefore, this utility model proposes a precast concrete energy storage compartment to address the shortcomings of existing technologies. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a precast concrete energy storage cabin, which aims to improve the existing technology of precast concrete energy storage cabins. These cabins have a single door and entrance sealing structure with low long-term reliability, are prone to rainwater seepage into the cabin under severe weather conditions, and have a roof drainage system that is easily blocked by debris and relies on manual cleaning, which poses a risk of leakage.

[0008] To achieve the above objectives, this utility model provides a precast concrete energy storage chamber, comprising: a chamber body and an access door; it also includes a threshold, a sealing assembly, and a cleaning assembly, wherein the access door is hinged to the chamber body, the threshold is fixed to the inner side wall of the chamber body, and the access door is rotatably disposed within the threshold.

[0009] The sealing assembly includes a first fixing strip, a rubber plate, a connecting block, a sliding rod, a second fixing strip, a return element, a fixing rod, and a step strip. The first fixing strip and the second fixing strip are both fixed to the outside of the door and exit. The connecting block is slidably connected to the second fixing strip. One end of the sliding rod is connected to the connecting block, and the other end is connected to the rubber plate. The step strip is located between the two door and exit doors. The return element and the fixing rod are both connected to the step strip.

[0010] Preferably, the top of the box is provided with a flow channel and a water guide is provided, the water guide being connected to the flow channel.

[0011] Preferably, the cleaning assembly includes a sliding block, an L-shaped strip, a rotating shaft, a fixed block, a telescopic component, and a scraper; wherein, the fixed block is installed on the top of the housing; the telescopic component is connected to the fixed block; the L-shaped strip is connected to the output end of the telescopic component; the sliding block is rotatably connected to the L-shaped strip via the rotating shaft; and the scraper is connected to the sliding block.

[0012] Preferably, the step bar includes a first step portion and a second step portion, the first step portion and the second step portion rotating between the two access doors respectively, and when the access doors are closed, the first step portion and the second step portion overlap each other.

[0013] Preferably, the first fixing strip has a groove, and the connecting block is slidably fitted into the groove.

[0014] Preferably, the lower end of the scraper is disposed in the guide groove, and the sliding block slides along the extension direction of the guide groove.

[0015] Preferably, the movement of the telescopic member drives the L-shaped strip to move, and the L-shaped strip causes the scraper to descend into the guide groove via the rotating shaft.

[0016] Preferably, the housing is also provided with a heat dissipation door, a heat dissipation window, and an air intake.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting a sealing component consisting of stepped strips, connecting blocks, sliding rods, and rubber plates, when the door is closed, the overlapping of the stepped strips forms a tortuous sealing path, and the connecting blocks drive the sliding rods and rubber plates to actively press the door gaps. This solves the problems of poor sealing of existing prefabricated cabin door gaps, poor waterproof and windproof performance, and easy damage to internal equipment due to moisture. It achieves a multi-seal effect, significantly improves the waterproof and windproof level of the cabin, and ensures the safe and stable operation of the equipment inside the cabin.

[0019] 2. This utility model solves the problems of easy clogging, poor drainage, and water leakage in existing prefabricated cabin top drainage channels by setting a cleaning component consisting of telescopic parts, L-shaped strips, sliding blocks, and scrapers on the top of the cabin. The telescopic parts drive the scrapers to slide in the guide channel, pushing the silt to the water inlet for discharge. It also solves the problems of easy clogging, poor drainage, and water leakage in existing prefabricated cabin top drainage channels, as well as the inconvenience of manual cleaning and maintenance. It achieves the effect of automatic silt removal, ensures the long-term efficient operation of the drainage structure, reduces the risk of dampness in the cabin and pipeline corrosion, and reduces operation and maintenance costs.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 6 This utility model provides a precast concrete energy storage cabin, which aims to solve the problems of insufficient sealing performance of the cabin door in the existing technology, which easily leads to moisture in the internal equipment, and easy blockage of the drainage channel on the top of the cabin, which increases the difficulty of maintenance and the risk of leakage.

[0030] A precast concrete energy storage chamber includes a box body 1 and an entrance / exit door 7 hinged to the box body 1 by heavy-duty load-bearing hinges. In order to meet the heat dissipation requirements of the internal equipment, the box body 1 is also provided with a heat dissipation door 2 with rainproof louvers and embedded metal insect-proof net, a heat dissipation window 5 and an air inlet 4.

[0031] It also includes a heavy-duty steel threshold 9 or a threshold 9 cast integrally with the housing, as well as a sealing assembly 8 and a cleaning assembly 3. The threshold 9 is fixed to the inner wall of the housing 1 and provides a stable rotational support and a basic sealing surface for the door / exit 7. The door / exit 7 is rotatably set inside the threshold 9.

[0032] The sealing assembly 8 includes a first fixing strip 801, a rubber plate 802, a connecting block 803, a sliding rod 804, a second fixing strip 805, a return member 806, a fixing rod 807, and a step strip 808. The step strip 808 is located between the two door openings 7 and forms a tortuous physical barrier through its overlapping structure. To ensure its stability and function, the return member 806 is used to assist the step strip 808 in precise alignment when the door is closed, while the fixing rod 807 is connected to the step strip 808 to enhance its structural strength.

[0033] The first fixing strip 801 and the second fixing strip 805 are fixed to the outside of the door 7 by welding or bolting. The connecting block 803 is slidably connected to the second fixing strip 805, which serves as a guide rail. When the operator pushes the connecting block 803 to lock it, the connecting block 803 presses the weather-resistant rubber plate 802 at the other end against the door seam through the rigid sliding rod 804, forming a highly airtight elastic seal.

[0034] The top of the box 1 is provided with a guide channel, which is preferably U-shaped or V-shaped and extends along the length of the top of the box 1 to collect rainwater. A water guide 6 is provided at one end or the lowest point of the guide channel. The water guide 6 is a hollow pipe or a sloping baffle structure that connects to the guide channel and is used to discharge the rainwater and debris collected in the guide channel to the outside of the box 1.

[0035] The cleaning component 3 is located on the top of the housing 1. The cleaning component 3 includes a sliding block 301, an L-shaped strip 302, a rotating shaft 303, a fixing block 304, a telescopic component 305, and a scraper 306.

[0036] The fixing block 304 is a metal mounting bracket that is securely installed on the top of the housing 1 by welding or bolting. The fixing block 304 is located near one end of the guide channel.

[0037] The fixed end of the telescopic member 305 is connected to the fixed block 304, and the moving end of the telescopic member 305 is connected to the L-shaped strip 302. The telescopic member 305 is used to provide power for reciprocating motion.

[0038] L-shaped bar 302 is a rigid bending connecting rod. One end of L-shaped bar 302 is hinged or fixedly connected to the moving end of telescopic member 305, and the other end of L-shaped bar 302 is rotatably connected to sliding block 301 through rotating shaft 303.

[0039] The sliding block 301 is a sliding platform. The bottom of the sliding block 301 is slidably fitted on a guide rail set on the top of the housing 1 and parallel to the guide groove, or the side roller of the sliding block 301 is rolled on the side wall of the guide groove. The sliding block 301 slides back and forth along the extension direction of the guide groove.

[0040] The rotating shaft 303 is a pin or bearing structure. The rotating shaft 303 passes through the other end of the L-shaped strip 302 and the connecting hole of the sliding block 301, so that the L-shaped strip 302 and the sliding block 301 can rotate relative to each other.

[0041] The scraper 306 is a hard rubber plate. The upper end of the scraper 306 is fixedly connected to the bottom of the sliding block 301, and the lower end of the scraper 306 is set in the guide groove. The shape and size of the scraper 306 are adapted to the cross-sectional profile of the guide groove. The lower edge of the scraper 306 is preferably provided with an elastic rubber strip to better fit the inner wall of the guide groove.

[0042] To further improve the structural sealing performance of the door gap, the step strip 808 includes a first step and a second step. Both the first and second steps are L-shaped strip structures. The first and second steps rotate around the side edges of the two door / exit doors 7. When the door / exit door 7 is closed, the vertical surface of the first step and the vertical surface of the second step fit together, while the horizontal surface of the first step covers the horizontal surface of the second step, forming a tortuous and complex sealing path that effectively blocks wind and rain. The return element 806 is preferably a torsion spring. The return element 806 is connected between the step strip 808 and the door sill 9 and is used to assist the step strip 808 in automatically resetting when the door / exit door 7 is opened. The fixing rod 807 is a limiting rod or a reinforcing rod. The fixing rod 807 is connected to the step strip 808 and is used to increase the structural strength and stability of the step strip 808.

[0043] The first fixing strip 801 is a C-shaped channel steel structure or a metal strip with a T-shaped groove. The first fixing strip 801 has a sliding groove. The connecting block 803 is preferably a slider with a handle or knob. The back of the connecting block 803 is provided with a T-shaped block or dovetail block that matches the sliding groove. The connecting block 803 slides in the sliding groove, which makes it easy for the operator to push the connecting block 803 to slide along the sliding groove. The sliding rod 804 is a rigid metal connecting rod. The rubber plate 802 is an elastic sealing strip with a rectangular cross section. The rubber plate 802 is fixedly installed at the end of the sliding rod 804 away from the connecting block 803. When the connecting block 803 slides into place, the sliding rod 804 pushes the rubber plate 802 to press against the gap between the door 7 and the door frame of the box 1 to achieve active pressing and sealing.

[0044] The lower end of the scraper 306 is always positioned inside the guide channel. The sliding block 301 slides along the extension direction of the guide channel. The sliding block 301 is guided to perform linear reciprocating motion by the guide rail set on the top of the housing 1, ensuring that the scraper 306 can stably cover the entire length range of the guide channel.

[0045] The extension of the telescopic component 305 drives the L-shaped bar 302 to move. The L-shaped bar 302 rotates around its fulcrum near the telescopic component 305. The other end of the L-shaped bar 302 drives the sliding block 301 and the scraper 306 to move forward as a whole through the rotating shaft 303. At the same time, the rotation of the L-shaped bar 302 causes the scraper 306 to descend to the cleaning position in the guide channel. The retraction of the telescopic component 305 pulls the L-shaped bar 302 to move in the opposite direction. The L-shaped bar 302 uses the linkage mechanism principle through the rotating shaft 303 to make the scraper 306 flip upward and lift it off the bottom of the guide channel, so that the scraper 306 can quickly and without resistance reset during the return stroke.

[0046] The enclosure 1 is also provided with a heat dissipation door 2 and a heat dissipation window 5. The heat dissipation door 2 is preferably a louvered structure with an openable door leaf, which is set on the side wall of the enclosure 1 to facilitate personnel to inspect and maintain the internal equipment. The heat dissipation window 5 is preferably a fixed louvered structure, which is set on the rear wall of the enclosure 1 or the side wall opposite to the heat dissipation door 2. The enclosure 1 is also provided with an air inlet 4, which is preferably set on the lower part of the side wall of the enclosure 1. The air inlet 4 and the heat dissipation window 5 are staggered at different heights to form a natural convection ventilation path where cold air enters from the bottom and hot air exits from the top. The openings of the heat dissipation door 2, the heat dissipation window 5 and the air inlet 4 are all provided with dustproof nets and waterproof louvers to prevent rainwater, sand and dust and insects from entering the interior of the enclosure 1.

[0047] Working principle: First, a door 7 is provided on one side of the housing 1. Opening the door 7 allows the equipment to be placed inside the housing 1. At the same time, a heat dissipation door 2 is provided on one side of the housing 1 for viewing the equipment. On the opposite side of the heat dissipation door 2, an air intake duct 4 is provided for air intake. A heat dissipation window 5 is provided at the rear of the housing 1. A water channel is provided on the top of the housing 1 for guiding the flow of water, which is discharged through a water guide 6. Then, a sealing component 8 is provided on the outside of the door 7 for sealing to prevent internal equipment failure. A cleaning component 3 is provided on the top of the housing 1 for cleaning the water channel.

[0048] When sealing the equipment, the outer side of the door 7 first rotates into the sill 9. A baffle is set on one side of the sill 9 for wind protection. The outer side of the door 7 is fixed with a first fixing strip 801 and a second fixing strip 805 respectively. Then, closing the door 7 causes the two step strips 808 to overlap. Due to the special nature of the step strips 808, the closing of the door 7 can achieve better sealing. At the same time, a return piece 806 and a fixing rod 807 are set at the connection between the step strips 808 and the door 7. During the closing process of the step strips 808, the return piece 806 is used to return to the center. Finally, the connecting block 803 on one side of the second fixing strip 805 is moved, which causes the sliding rod 804 and the rubber plate 802 to move to the first fixing strip 801. The connecting block 803 enters the groove of the first fixing strip 801, and the sliding rod 804 fits tightly against the door gap between the door 7 to complete the seal. This effectively improves the waterproof and windproof performance and ensures the stable and safe operation of the equipment inside the cabin.

[0049] During top cleaning, the scraper 306 inside the sliding block 301 is initially in a retracted state before activation. The telescopic component 305 is fixed to one side of the tank 1 via the fixing block 304. Then, the sliding block 301 extends and retracts, causing the L-shaped strip 302 to move. The L-shaped strip 302 is connected to the sliding block 301 via the pivot 303. The scraper 306 moves, causing the sliding block 301 to move. During this process, the scraper 306 moves downward, and the sliding block 301 moves, causing the scraper 306 to move in the guide channel of the tank 1, pushing the sludge to the water inlet 6. The sludge then slides off the water inlet 6, completing the cleaning. Finally, the accumulated debris in the trench is removed in a timely manner, ensuring the long-term efficient operation of the drainage structure, extending the life of the top drainage system, and reducing the risk of dampness and pipeline corrosion inside the tank.
