Description

Technical Field

[0001] This utility model relates to the field of port equipment and dustproof water supply technology, specifically to a dustproof and splashproof water tank fixed-point water filling device and a port machinery spray water storage system using the same. Background Technology

[0002] When loading and unloading bulk materials, rail-mounted port cranes at bulk cargo terminals generate a large amount of fugitive dust, requiring environmentally friendly spray systems to suppress it. These spray systems draw water from a fixed onboard tank, but the tank's capacity is limited, necessitating continuous replenishment. When the water in the tank is depleted, the crane is moved to a designated water replenishment point on the terminal ground or corridor. The onboard water tank's inlet is aligned with the terminal's water supply pipe inlet, simultaneously triggering a water-filling solenoid valve for automatic water replenishment. To achieve this, the water tank inlet must be directly below the terminal's water supply pipe inlet, meaning the tank cannot be sealed and must be exposed to the elements for precise filling. Because the existing onboard water tanks in these systems are exposed or semi-sealed, airborne dust and spilled materials from the crane can easily enter and contaminate the water source, causing blockages in the tank, pipes, and nozzles. This results in poor spray performance, a high failure rate, and increased maintenance difficulty. Furthermore, there is a certain height difference between the port machinery water storage tank and the water supply pipe above, which makes it impossible to accurately guide the water flow. During the fixed-point water supply process, there is a problem of water splashing, resulting in water waste.

[0003] In addition, the spray water tank on the port machinery has a capacity of eight cubic meters, and when full, it weighs more than eight tons. Its layout often needs to consider the requirements of force balance and no interference between the operation of various mechanisms. At present, the water inlet of the dock is generally on the ground or in the corridor. The water tank of the port machinery needs to be placed directly below the water inlet of the dock water pipe. The spray water tank on the port machinery, which weighs eight tons, needs to be placed in a protruding position close to the ground or the side of the corridor to complete the fixed-point water filling normally. Considering the force balance and the stability of the center of gravity, the steel structure platform at the bottom of the water tank needs to be reinforced. During the fixed-point water filling process of the trolley, the steel structure platform and guardrail of the port machinery itself must not interfere with the ground or corridor water pipe.

[0004] Currently, the water storage tanks on existing ship loaders are limited by installation location. They must be installed directly below the designated water inlet with an exposed opening. The area above the tank is either open or semi-sealed, making it easy for airborne dust and spilled materials from the port machinery to enter and contaminate the water source. This causes blockages in the tank, pipes, and nozzles, affecting the environmental spraying effect of the port machinery, resulting in a high failure rate and increased maintenance difficulty. Furthermore, the existing ship loaders have a height difference between the upper water inlet pipe and the onboard water storage tank, making it impossible to precisely guide the water flow. This leads to water splashing during designated water filling, resulting in water waste. Utility Model Content

[0005] The purpose of this invention is to provide a dustproof and splashproof water tank point-filling device to improve the dustproof sealing capability of port machinery water tanks and reduce the impact of water splashing outwards during point-filling. Another purpose of this invention is to provide a port machinery spray water storage system using the aforementioned dustproof and splashproof water tank point-filling device. This system not only improves the dustproof sealing capability of port machinery water tanks and reduces the amount of water splashing outwards during point-filling, but also avoids the problem of limited installation location for port machinery water tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model proposes a dustproof and splashproof water tank fixed-point water filling device. The water outlet of the water tank fixed-point water filling device is connected to the water inlet of the water tank of the port machinery by a pipe. The water tank fixed-point water filling device is used to cooperate with a water filler to fill water at a fixed point. The water filler moves laterally relative to a reference system. The water tank fixed-point water filling device includes a dustproof and splashproof shield box and an extension water pipe arranged sequentially from high to low.

[0008] The dustproof and splashproof shielding box is used to prevent dust from entering the inlet of the extended water pipe and to prevent water from splashing outwards when the water dispenser adds water. Multiple water-blocking strips are installed on a partially open but partially covered side of the dustproof and splashproof shielding box to block water splashes. The area of ​​this part of the side is not less than half the total area of ​​all sides of the dustproof and splashproof shielding box. When the water dispenser passes laterally across the space between the top and bottom surfaces of the dustproof and splashproof shielding box relative to a reference frame, the corresponding water-blocking strips are opened. When the water dispenser is adding water in this space, each water-blocking strip prevents water splashes from reaching the outside of the dustproof and splashproof shielding box, thus concentrating the water flow from the water dispenser through the outlet of the extended water pipe to the water tank.

[0009] The extended water pipe is used to divert water to be added to the dustproof and splashproof shielding box to the water tank; the outlet of the extended water pipe is the outlet of the water tank's fixed-point water filling device, and the inlet of the extended water pipe is connected to the outlet of the dustproof and splashproof shielding box.

[0010] Furthermore, the top, back, and bottom surfaces of the dustproof and splashproof shielding box are respectively a top plate, a back plate, and a funnel. The outlet of the funnel is the outlet of the dustproof and splashproof shielding box. Multiple water-blocking rubber strips are installed on the virtual left side, virtual right side, and virtual front of the dustproof and splashproof shielding box.

[0011] Furthermore, the dustproof and splashproof shielding box is fixedly installed on the port machinery via a fixed bracket.

[0012] Furthermore, the funnel includes a bottom with a water outlet and a surrounding edge; when the water dispenser does not pass laterally across the space between the top and bottom surfaces of the dustproof and splashproof shielding box, the vertical positions between the top plate of the dustproof and splashproof shielding box and the left side of the surrounding edge, the vertical positions between the top plate of the dustproof and splashproof shielding box and the right side of the surrounding edge, and the vertical positions between the top plate of the dustproof and splashproof shielding box and the front of the surrounding edge are all shielded by multiple liftable water-blocking strips.

[0013] Furthermore, the top of each water-blocking strip is respectively installed on the corresponding edge of the top plate of the dustproof and splashproof shielding box or on the corresponding lower extension edge plate extending downward from the edge of the top plate of the dustproof and splashproof shielding box.

[0014] Furthermore, the inlet of the extended water pipe is positioned so that its top-down structural projection is far from the top-down structural projection of the water tank.

[0015] Furthermore, the structural projection of the dustproof and splashproof shielding box from a top-down view is far from the structural projection of the water tank from a top-down view.

[0016] Furthermore, in the vertical direction, an extension water pipe is installed between the dustproof and splashproof shielding box and the water tank.

[0018] Port machinery used for lateral movement during unloading / loading;

[0022] Furthermore, the port machinery spray water storage system also includes a water pump, the water pump inlet of which is connected to a water storage tank, and the water pump outlet of which is connected to the water dispenser through the water supply pipe.

[0023] The water dispenser is a water pipe elbow with the outlet facing downwards;

[0024] The outlet of the extended water pipe is connected to the inlet of the water tank, and the pipe opening is spliced ​​and sealed.

[0025] The extension pipe extends away from the water tank in a top-view projection direction;

[0026] The virtual line connecting the outlet of the dustproof and splashproof shielding box and the inlet of the water tank in the top-view projection direction forms an angle with the lateral movement direction of the port machinery.

[0027] The extension water pipe is located below a port machinery corridor, and the water tank is located inside the corridor.

[0028] The beneficial effects of this utility model are as follows:

[0041] like Figures 1-3 As shown:

[0042] This embodiment proposes a dustproof and splashproof water tank fixed-point water filling device. The water outlet of the water tank fixed-point water filling device is connected and communicated with the water inlet of the water tank 100 of the port machinery 200. The water tank fixed-point water filling device is used to cooperate with a water filler 3 to perform fixed-point water filling. The water filler 3 moves laterally relative to a reference system. The water tank fixed-point water filling device includes a dustproof and splashproof shield box 2 and an extension water pipe 1 arranged sequentially from high to low and communicated with each other.

[0043] The dustproof and splashproof shielding box 2 is used to prevent dust from entering the inlet of the extension water pipe 1 and to prevent water from splashing outwards when water is added by the water dispenser 3. Multiple water-blocking strips 20 are installed on a partially open but partially covered side of the dustproof and splashproof shielding box 2 to block water splashes. The area of ​​this part of the side is not less than half the total area of ​​all sides of the dustproof and splashproof shielding box 2. When each water-blocking strip 20 is lifted, this part of the side is open. When the water dispenser 3 passes laterally across the space between the top surface 21 and the bottom surface 23 of the dustproof and splashproof shielding box 2 relative to a reference frame, the corresponding water-blocking strip 20 is lifted. When the water dispenser 3 is filling water in this space, each water-blocking strip 20 is used to prevent water splashes in this space from reaching the outside of the dustproof and splashproof shielding box 2, thereby concentrating the water flow from the water dispenser 3 through the outlet of the extension water pipe 1 to reach the water tank 100.

[0044] The extension water pipe 1 is used to guide the water to be added to the dustproof and splashproof shielding box 2 to the water tank 100; the outlet of the extension water pipe 1 is the outlet of the water tank fixed-point water filling device, and the inlet of the extension water pipe 1 is connected to and communicates with the outlet of the dustproof and splashproof shielding box 2.

[0045] Specifically, the dustproof and splashproof shielding box 2 can be in the shape of a cuboid, cube, drum, or cage, and the shape can be designed according to the actual manufacturing process and application scenario requirements.

[0046] Ideally, the top surface 21, the rear surface 22, and the bottom surface 23 of the dustproof and splashproof shielding box 2 are respectively a top plate, a rear plate, and a funnel.

Multiple water-blocking rubber strips 20 are installed on the virtual left side 24, the virtual right side 25, and the virtual front side 26 of the dustproof and splashproof shielding box 2.

[0047] As an optional optimized implementation, the extension water pipe 1 also serves as a support arm for the dustproof and splashproof shielding box 2; the inlet of the extension water pipe 1 is connected to the outlet of the funnel and welded and fixed.

[0048] As another optional optimized implementation, the dustproof and splashproof shielding box 2 is fixedly installed on the port machinery 200 by a fixed bracket.

[0049] Optimally, the funnel includes a funnel bottom with a water outlet and a funnel rim 232; when the water dispenser 3 does not pass laterally across the space between the top surface 21 and the bottom surface 23 of the dustproof and splashproof shielding box 2, the vertical positions between the top plate of the dustproof and splashproof shielding box 2 and the left side of the funnel rim 232, the vertical positions between the top plate of the dustproof and splashproof shielding box 2 and the right side of the funnel rim 232, and the vertical positions between the top plate of the dustproof and splashproof shielding box 2 and the front of the funnel rim 232 are all shielded by multiple liftable water-blocking strips 20.

[0050] Ideally, the top end of each water-blocking strip 20 is installed on the corresponding edge of the top plate of the dustproof and splashproof shielding box 2 or on the corresponding lower extension edge plate 211 extending downward from the edge of the top plate of the dustproof and splashproof shielding box 2.

[0051] Further optimized, the inlet of the extended water pipe 1 is positioned so that its downward structural projection is far from the downward structural projection of the water tank 100.

[0052] Further optimized, the dustproof and splashproof shielding box 2 is positioned so that its downward structural projection is far from that of the water tank 100.

[0053] In a further optimized manner, the dustproof and splashproof shielding box 2 is higher than the water tank 100, and in the height direction, the extended water pipe 1 is arranged between the dustproof and splashproof shielding box 2 and the water tank 100.

[0054] Example 2

[0055] like Figures 1-4 As shown:

[0056] This embodiment also proposes a port machinery spray water storage system, including:

[0057] Port machinery 200 for lateral movement during unloading / loading;

[0058] Water tank 100 installed on port machinery 200;

[0059] As described in any of the technical solutions of Embodiment 1, the water tank fixed-point water filling device is connected to the water tank 100;

[0060] Water dispenser 3; the reference frame of the water dispenser 3 passing laterally through the dustproof and splashproof shield box 2 is the port machinery 200; the water dispenser 3 is connected to and communicates with a water supply pipe 300, and the water supply pipe 300 raises the water dispenser 3 and fixes it in a first fixed position; the space between the top surface 21 and the bottom surface 23 of the dustproof and splashproof shield box 2 is the first space; in a virtual space rectangular coordinate system, the vertical height of the first fixed position is consistent with the vertical height of the first space (i.e., the same or overlapping), the longitudinal position of the first fixed position is consistent with the longitudinal position of the first space (i.e., the same or overlapping), and the lateral direction of the virtual space rectangular coordinate system is the lateral movement direction of the port machinery 200.

[0061] Optimized, the port machinery spray water storage system also includes a water pump 500, the inlet of which is connected to a water storage tank, and the outlet of which is connected to the water supply pipe 300 through the water supply pipe 300.

[0062] The water dispenser 3 is a water pipe elbow with the outlet facing downwards;

[0063] The outlet of the extension water pipe 1 is connected to the inlet of the water tank 100 and the pipe openings are spliced ​​and sealed.

[0064] The extension pipe 1 extends away from the water tank 100 in the top view projection direction;

[0065] The virtual line connecting the virtual center point of the outlet of the dustproof and splashproof shielding box 2 and the virtual center point of the inlet of the water tank 100 in the top-view projection direction forms an angle with the lateral movement direction of the port machinery 200.

[0066] Below the extended water pipe 1 is a corridor 400 for the port machinery 200, and the water tank 100 is located inside the corridor 400.

[0067] Example 3

[0068] Example 3 is a further optimized design of Example 2;

[0069] like Figures 1-4 As shown:

[0070] A dustproof and splashproof water filling device is designed above the water tank of the port machinery (i.e., the water tank 100 of the port machinery 200). When the water tank of the port machinery needs to be replenished, when the trolley of the port machinery 200 moves to the designated water filling position at the dock, the inverted "L"-shaped water pipe on the ground (i.e., the water filler 3 in conjunction with part of the water supply pipe 300) breaks open the soft rubber anti-overflow water curtain (i.e., the water-blocking rubber strip 20) around the water filling funnel (i.e., the dustproof and splashproof shield box 2) and enters the water filling port to fill the water tank on the machine. When the water tank of the port machinery is full, when the trolley of the port machinery 200 leaves to the designated water filling position at the dock, the inverted "L"-shaped water pipe on the ground extends out of the dustproof and splashproof shield box 2, and the soft rubber anti-overflow water curtain around the water filling funnel closes again to seal the water filling funnel and prevent dust and spilled materials from the port machinery 200 from easily entering the water tank and contaminating the water source.

[0071] Specifically, the port machinery 200 is a bulk cargo terminal rail-mounted port machinery used for loading and unloading bulk materials. During operation, the port machinery 200 moves on the ground track or the tail car corridor track via the trolley mechanism's traveling wheels or the tail car's traveling wheels. Its spraying device draws water from the fixed water tank (i.e., water tank 100) on the machine. The water tank has a limited capacity, and water needs to be replenished when the water level is low. When the water in the water tank 100 is used up, the port machinery 200 will move to the position of the water supply pipe 300, and the water inlet of the dustproof and splashproof shield box 2 will be aligned with the water outlet of the water adder 3, and at the same time, the water addition sensing solenoid valve will be triggered to realize automatic water addition.

[0072] Ideally, the port machinery spray water storage system also includes a water inlet switch, which is connected to the port area water supply pipeline. When the water inlet switch is turned on, the terminal's environmentally friendly water can enter the water supply pipeline 300, and the environmentally friendly water is supplied under its own pressure.

[0073] Ideally, the water tank 100 is arranged on the port machinery 200 platform, and the top plate of the top surface 21 of the dustproof and splashproof shielding box 2 is fixed to the port machinery 200 platform by welding.

[0074] Ideally, the water tank 100 is connected to the extension water pipe 1, which serves as a guide pipe. The water tank 100 can be made of 304 stainless steel and has a volume of up to eight cubic meters. Water is injected into the water tank 100 through the extension water pipe 1, and the connection between the extension water pipe 1 and the water tank 100 is sealed.

[0075] Ideally, the top of the dustproof and splashproof shielding box 2 is equipped with a sealed cover and three openings. The top and bottom of the dustproof and splashproof shielding box 2 can be made of 304 stainless steel, and the water filler 3 can enter the dustproof and splashproof shielding box 2 to fill it with water.

[0076] Ideally, each water-blocking rubber strip 20 is installed on the three open surfaces of the dustproof and splashproof shielding box 2, and is made of soft rubber. It is fixed to the dustproof and splashproof shielding box 2 with fixing clamps and fixing screws. During the fixed-point water addition process, the water-blocking rubber strip 20 effectively prevents water from splashing.

[0077] Ideally, the water collection funnel of the dustproof and splashproof shielding box 2 is connected to the water filling funnel cover (i.e., the top plate of the dustproof and splashproof shielding box 2), and the water collection funnel of the dustproof and splashproof shielding box 2 forms an inverted "quadrangular pyramid" structure, which is welded and fixed; specifically, a 100mm diameter circular hole is opened at the bottom of the dustproof and splashproof shielding box 2.

[0078] Ideally, the extension water pipe 1 is connected to the bottom of the water collection funnel of the dustproof and splashproof shielding box 2 and fixed to the bottom of the funnel with a hose clamp. The extension water pipe 1 is a transparent flexible hose with a steel wire head made of PVC material.

[0079] Ideally, the extension water pipe 1 is fixed on the steel frame in an inverted L-shape, with five diagonal braces, all of which are 10# hot-dip galvanized I-beams, and is fixed to the corridor surface of the port machinery 200 with expansion bolts.

[0080] The water supply pipe 300 connected to the water dispenser 3 can be made of PPR material, preferably DN50; and a water pipe is laid between the water storage tank and the water inlet, and fixed every five meters using angle steel and U-shaped clamps.

[0081] Specifically, during the fixed-point water filling process, the water collection funnel of the dustproof and splashproof shield box 2 can effectively collect the water flow and introduce it into the water tank 100 through the extension water pipe 1; the height of the dustproof and splashproof shield box 2 can be adjusted according to the position of the water tank 100 on the port machinery 200, and it is arranged on the port machinery 200 by a fixed bracket; since the water tank 100 on the port machinery 200 cannot be interfered with by surrounding objects, it cannot be installed directly below the fixed-point water filling port, while the installation position of the dustproof and splashproof water tank fixed-point water filling device is flexible and does not need to consider the adjustment of the center of gravity when the water tank is full of water, and the length of the extension water pipe 1 can be flexibly selected according to the actual needs of the position of the water tank 100.

[0082] The dustproof and splashproof water tank fixed-point water filling device of this utility model and the port machinery spray water storage system using it also have the following advantages:

[0083] This utility model features a high degree of automation in water addition, resulting in faster and more efficient water addition. It eliminates the need for dock personnel to assist in operation, saving time, effort, and labor costs.

[0084] This invention solves the problem that water storage tanks for fixed-point water replenishment of port machinery cannot achieve dustproof sealing; it prevents air dust and spilled materials from entering the water tank and contaminating the water source, protects the water tank, pipelines, and nozzles from clogging, reduces the failure rate and maintenance difficulty; it can effectively avoid water waste during fixed-point water replenishment, and has a simple structure and is easy to maintain.

[0085] This utility model can solve the problem of limited installation location of water storage tank on fixed-point water supply machine, and can flexibly choose the installation location, which is not affected by the center of gravity of the water tank and does not interfere with the surrounding platform and guardrail;

[0086] This invention precisely guides the water flow, eliminating water splashing during point-to-point water filling and preventing water waste.

[0087] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
