Description

Technical Field

[0001] This application relates to the field of salt field equipment, and in particular to an intelligent polymer protective device for smart salt fields. Background Technology

[0002] In salt field production, especially in the protection of crystallization ponds, effectively preventing brine leakage and resisting external environmental interference (especially rainwater) is crucial. Current technologies generally employ the laying of entire sheets of high-molecular polymer membranes (such as HDPE and PVC) or their integration with concrete structures to protect the pond base and sidewalls. While these materials and technologies possess a certain degree of impermeability, long-term exposure to the harsh environment unique to salt fields (strong ultraviolet radiation, high-concentration brine chemical corrosion, frequent wet-dry cycles, temperature changes, and potential mechanical stress) presents a common and serious core problem—accelerated material aging and failure. This manifests primarily as: loss of surface gloss, significantly increased brittleness, a sharp decline in tensile strength and elongation, and weakened puncture and tear resistance, ultimately leading to cracks, holes, or even large-scale brittle fracture in the protective layer, resulting in the loss of its protective function. This performance degradation caused by aging not only necessitates periodic and costly replacement of the entire protective structure but also causes production interruptions and brine losses during replacement downtime. Even more challenging is the fact that existing protective structures are completely static and passive in the event of sudden rainfall. They are unable to sense the arrival of rain, nor do they have any proactive mechanism to quickly isolate and protect the area (especially the crystallization pool). Rainwater can easily enter the pool and dilute the high-concentration brine, which can hinder the salt crystallization process or reduce the quality of the finished salt, resulting in direct economic losses.

[0003] The key reasons why protective structures are particularly prone to aging and failure, and lack the ability to withstand rainwater, can be summarized in two main points: First, existing protective layers are mostly integrated fixed structures or single-sheet membrane materials. Once areas exposed to the harshest environments and aging fastest (such as areas subjected to prolonged direct sunlight and brine level fluctuations) fail, repairs or even large-scale replacement of the entire material are often necessary, resulting in high costs, low efficiency, and poor targeting. Second, current protective design concepts focus on static isolation; the materials themselves lack the ability to sense environmental changes (such as rainfall), and the entire system lacks an active protective actuator capable of rapid deployment and localized coverage of critical areas (such as crystallization pools) under specific environmental threats (rainfall). The low maintainability of the material system and the lack of intelligent response jointly limit the effectiveness and lifespan of salt field protection.

[0004] Therefore, the core objective of developing a new type of intelligent protection device for smart salt fields is to solve the aforementioned problem of material aging and achieve intelligent protection against rainwater intrusion. Utility Model Content

[0005] The purpose of this application is to overcome at least one deficiency of the existing technology and to provide an intelligent polymer protective device for smart salt fields.

[0006] To achieve the above objectives, this application discloses an intelligent polymer protective device for smart salt fields. The protective device is composed of side-block components and active rain-shielding components working together. The four side-block components are connected end to end to form a closed rectangular enclosure structure, which defines the crystallization area of ​​the salt field and abuts against the pond embankment.

[0007] The side barrier assembly includes a main support frame made of fiberglass. A transparent protective glass layer is fixed to one side surface of the main support frame facing the inside of the barrier structure. The protective glass layer is reliably connected to the main support frame by a continuous adhesive layer or spaced mechanical fasteners. A parallel, spaced interlayer cavity is provided between the main support frame and the transparent protective glass layer. Several independent, replaceable insert plates are inserted into the interlayer cavity. As the first protective layer that is in direct contact with the environment, the insert plate functions to block ultraviolet radiation and brine erosion to slow down the aging process of the main support frame. When a single insert plate shows significant discoloration or physical deterioration, it can be replaced individually without disassembling the entire structure.

[0008] The active rain shelter assembly consists of a fixed base, an electrically movable support, and a foldable protective tarpaulin connecting the two. The fixed base is fixedly installed at one end of the enclosure structure. The bottom of the electrically movable support is equipped with a drive wheel set. A linear guide rail is laid along the length of the top of the main support frame in the enclosure structure to guide the movement of the movable support. Multiple intermediate linkage supports are hinged between the fixed base and the movable support. Each linkage support is connected end to end through a linkage folding mechanism. The protective tarpaulin is fixed to the top of the linkage support. When the drive wheel set moves along the linear guide rail, the linkage support unfolds synchronously and drives the protective tarpaulin to extend into an arched shelter surface.

[0009] The top of the electrically operated mobile support is integrated with a rainfall detection unit, and temperature and humidity sensing modules are respectively installed at the four corners of the enclosure structure. When the rainfall detection unit detects that the precipitation reaches a preset threshold, it triggers the electrically operated mobile support to move along a linear guide rail. During the movement, the intermediate linkage support extends, causing the protective tarpaulin to fully unfold above the enclosure structure, forming a continuous arched shielding surface covering the crystallization area, thereby preventing rainwater from mixing with the brine and causing a decrease in concentration. After the shielding operation is completed, the mobile support moves in the opposite direction, causing the protective tarpaulin to fold back to its original position.

[0010] Furthermore, guide ribs are provided on both sides of the insert plate, and continuous insertion grooves are provided at corresponding positions on the inner side of the main support frame. After the insert plate is pushed longitudinally into the interlayer cavity along the groove, its top is locked by an elastic limiting buckle.

[0011] Furthermore, the top center of the insert plate has an embedded lifting groove. When replacement is needed, force is applied to the lifting groove to release the elastic limiting buckle constraint, and the old insert plate can be completely pulled out along the sliding groove.

[0012] Compared with existing technologies, this device achieves optimized protection through the following technical effects: the modular insert plate design reduces the maintenance cost of the main frame while improving the efficiency of local replacement; the integrated sensing system monitors environmental parameters in real time and triggers responses; the arched deployment mechanism ensures the reliability of shielding operations and water accumulation prevention performance; and the overall configuration maintains the continuity of salt field production and ensures brine quality.

[0021] The following is an embodiment of an intelligent polymer protective device for smart salt fields, which aims to achieve multi-level environmental protection for the crystallization area of ​​salt fields through structural integration and intelligent control.

[0022] See attached document Figures 1 to 3 The overall structure of the device consists of a barrier structure formed by four side barrier components 1 connected end to end around the edge of the salt field embankment, and a set of active rain-shielding components 2 set on top of the barrier structure, forming a composite intelligent protection system covering the salt field crystallization pond area.

[0023] In the specific structure, each side shield assembly 1 includes an integrally formed main support frame 101. This main support frame 101 is preferably made of fiberglass reinforced plastic (FRP) material, possessing good corrosion resistance and mechanical strength, and its cross-sectional structure is a triangular frame shape. A transparent protective glass layer 102 is fixedly installed on the side surface of the main support frame 101 facing the interior of the salt field. The protective glass layer 102 is fixed to the support frame by a continuously arranged high-strength adhesive layer or by bolted fasteners arranged along the edge. Preferably, bolted fasteners are used for connection and fit.

[0024] A pre-set, parallel-spaced interlayer cavity 103 is provided between the main support frame 101 and the protective glass layer 102. Several replaceable insert plates 104 are arranged within this cavity 103 along the insertion direction. Preferably, the insert plates 104 are made of a dark polymer material with an anti-UV coating to absorb and block strong ultraviolet radiation, while also providing physical isolation from corrosive droplets generated by brine splashing. Each insert plate 104 has guide ribs on both sides for insertion guidance; correspondingly, a continuous sliding groove is provided on the inner wall of the main support frame 101 along the insertion direction, allowing the insert plate 104 to slide into the cavity 103. After insertion, the top of the insert plate 104 is locked by an elastic limiting buckle 105 located on the upper edge of the main support frame 101 to prevent displacement under wind load or vibration conditions. To facilitate later maintenance and replacement, the top center of the insert plate 104 is provided with an integrated lifting groove. The operator can apply force to this groove to release the elastic limiting buckle 105 and then pull out the failed insert plate 104 along the sliding groove for quick replacement. The above structural design ensures that when the insert plate is damaged due to environmental aging, discoloration, or surface damage, it can be replaced piece by piece without disassembling the whole plate, effectively reducing maintenance costs.

[0025] An active rain-shielding component 2 installed at the top of the enclosure structure automatically deploys to provide shelter when rain is detected, preventing precipitation from diluting the brine concentration in the crystallization area. This active rain-shielding component 2 includes a fixed base 201 installed at one end of the enclosure structure, an electrically movable support 202 that can move along a guide rail, and a foldable arched protective tarpaulin 203 linked between the two. The electrically movable support 202 integrates a motor drive system to provide power for deployment and retraction. Specifically, the bottom of the electrically movable support 202 is equipped with a drive wheel set, which can travel along a linear guide rail along the length of the upper surface of the enclosure structure. The guide rail is made of corrosion-resistant stainless steel and is fixedly connected to the main support frame 101 in the enclosure structure using an embedded installation method.

[0026] The top of the electric mobile support 202 is equipped with multiple intermediate linkage supports 204 that are hinged sequentially. These linkage supports 204 are connected by a linkage folding mechanism to simultaneously flatten or fold. When the electric mobile support 202 moves forward on the guide rail, the linkage supports 204 unfold in tandem, causing the protective tarpaulin 203 fixed above it to unfold segment by segment, forming an arched shelter. Preferably, the protective tarpaulin 203 is made of highly elastic fluorinated fiber material, possessing excellent weather resistance and water-resistant capabilities. The arched structure design effectively guides rainwater to drain along the side edges, preventing the formation of puddles.

[0027] In terms of automatic control, the top of the electric mobile support 202 integrates a rainfall detection unit, and temperature and humidity sensing modules are respectively installed at the top corners of the four side shield components 1. These sensors are connected to an external control system or controller to form a real-time environmental monitoring network. When the rainfall sensor detects that the instantaneous or cumulative rainfall exceeds a preset threshold, the system or controller issues a start command, and the electric mobile support 202 unfolds the linkage support 204 along the guide rail, while simultaneously unfolding the protective tarpaulin 203, forming a continuous shielding structure covering the salt field to prevent rainwater from mixing into the salt pond. After the rainfall ends, the control system triggers a reverse action, driving the mobile support back to its original position, while the linkage support folds and drives the tarpaulin back to its initial state, achieving automatic closure. Details such as sensor parameter settings, signal acquisition, and data judgment logic are well known to those skilled in the art and will not be elaborated here.

[0028] In practical applications, when salt fields are under high temperatures and intense sunlight during the crystallization stage, and when occasional rainfall is frequent, the deployment of the aforementioned protective devices can continuously ensure stable lighting conditions in the crystallization pool area, prevent impurities from entering, and improve salt purity and production efficiency. Compared to the traditional method of relying on manual tarpaulin covering, the device described in this invention can significantly reduce manpower input, improve response speed, and, due to its local maintenance capability, significantly reduce long-term operation and maintenance costs, greatly improving system reliability. This structure can also be extended to other outdoor industrial production scenarios requiring environmental protection, such as sun-dried ponds and open chemical reaction tanks, demonstrating good adaptability and promotional value.

[0029] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims. This disclosure is defined by the appended claims, and equivalents of those claims are also included.
