Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology, specifically to a dustproof device for the electric tank opening of a sprinkler truck. Background Technology
[0002] Water trucks play a crucial role in urban environmental maintenance and road cleaning. They effectively suppress road dust and maintain a clean and moist urban environment by spraying water mist or streams. However, during operation, the tanks of water trucks need to be replenished with water regularly or as needed to ensure continuous operation.
[0003] Traditional water replenishment methods often require manually opening the water inlet cap and connecting the water pipe. This process is not only time-consuming and labor-intensive, but improper operation can also lead to water waste and environmental pollution.
[0004] In the existing technology, a method has been developed to address the opening and closing problem of the water inlet cap, which can enable the water inlet cap to open and close automatically through an external drive structure, without the need for manual opening of the water inlet cap.
[0005] While the aforementioned device can automatically open and close the water inlet cap, its drive structure includes a worm gear meshing mechanism for transmission. This transmission structure is directly exposed to the external environment. Since water trucks frequently operate in complex and changing outdoor environments, such as dusty construction sites and muddy roads, dust, debris, and other pollutants easily accumulate in the grooves of the worm or worm gear. If these pollutants affect the meshing effect of the worm and worm gear, it will lead to a decrease in transmission efficiency, or even cause the transmission structure to jam, thus affecting the normal opening and closing of the water inlet cap. Utility Model Content
[0006] In view of this, the present invention provides a dustproof device for the electric tank opening of a sprinkler truck. The present invention can protect the transmission structure, thereby preventing dust and debris from affecting the transmission effect of the transmission structure.
[0007] To solve the above-mentioned technical problems, this utility model provides a dustproof device for the electric tank opening of a sprinkler truck, including a tank opening body and a drive mechanism disposed on the side of the tank opening body. The drive mechanism can indirectly drive the opening and closing of the water supply cover. The drive mechanism includes a drive chamber and a transmission chamber disposed between the drive chamber and the tank opening body. The transmission chamber includes a rotatable worm gear. The outer surface of the worm gear is fixedly connected to the water supply cover of the tank opening body. The rotation of the worm gear can drive the water supply cover to rotate. Movable rods extend from both ends of the worm gear. The movable rods can rotate with the worm gear. Multiple dustproof plates are rotatably disposed between two movable rods. The dustproof plates have an arc-shaped structure. Every two adjacent dustproof plates are connected to each other. The multiple dustproof plates are arranged in a semi-circular shape. The two outermost dustproof plates are respectively connected to the drive chamber and the top of the water supply cover. At the same time, during the opening and closing of the water supply cover, they expand or fold synchronously with the rotation of the worm gear to form a dynamic sealing barrier.
[0008] Each dust cover has a first extension plate on the outer surface of the end near the drive compartment, and a second extension plate on the inner surface of the end near the water inlet cover. The first extension plate and the second extension plate form an overlapping limiting structure. The first extension plate and the second extension plate can make the adjacent dust cover rotate when the dust cover rotates, preventing the adjacent dust cover from falling off.
[0009] The first extension plate and / or the second extension plate are arc-shaped strip structures, and the cross-sections between the first extension plate and the second extension plate and the connected dustproof plate are both L-shaped structures.
[0010] Each dustproof plate has movable rings at both ends. The movable rings are coaxially arranged with the movable rod, and the movable rings are sleeved on the movable rod to achieve a rotatable connection.
[0011] The movable rod is detachably fixed to the worm gear, making it easy to disassemble.
[0012] The end of the movable rod is fixed to the end of the worm gear by a threaded connection, which allows for quick disassembly of the movable rod.
[0013] The end of the movable rod away from the worm gear is equipped with a force-applying structure, which facilitates the application of force to the movable rod, thereby making it easier to rotate.
[0014] The force-applying structure is a slot at the end of the movable rod.
[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0016] 1. Effective Dust Protection: Multiple dustproof plates are arranged in a semi-circle around the worm gear, and they expand or fold synchronously with the rotation of the worm gear during the opening and closing of the water inlet cover, forming a dynamic sealing barrier. This design effectively prevents dust, debris, and other contaminants from the external environment from entering the transmission chamber, avoiding transmission efficiency reduction or jamming caused by contamination of the worm gear and other transmission structures. This ensures the normal opening and closing of the water inlet cover and the continuous operation capability of the sprinkler truck.
[0017] 2. Stable and reliable structure: The dustproof plates are connected to each other by an overlapping limiting structure formed by the first extension plate and the second extension plate. This design not only enhances the connection strength between the dustproof plates and prevents them from detaching during rotation, but also allows the dustproof plates to unfold and fold smoothly, ensuring the stability and reliability of the dustproof device.
[0018] 3. Easy maintenance and replacement: The movable rod is detachably fixed to the worm gear via a threaded connection. This design allows for convenient and quick disassembly of the movable rod and dust cover when maintenance or replacement of the dust cover is required, reducing maintenance and time costs. Simultaneously, the end of the movable rod furthest from the worm gear has a force-applying structure (such as a slotted groove), facilitating force application by the operator and further simplifying the maintenance process.
[0019] 4. High adaptability: The dustproof plate adopts an arc-shaped structure and is rotatably connected to the movable rod via a movable ring. This design allows the dustproof device to adapt to rotation at different angles and directions, ensuring the continuity of dustproof effect during the opening and closing of the water supply cover. Furthermore, the overall structure of the dustproof device is compact and reasonable, not occupying excessive space, and is suitable for various models of sprinkler trucks.
[0020] 5. Improved Operational Efficiency: This invention effectively solves the problem of contamination in the transmission structure, avoiding delays or malfunctions in the opening and closing of the water supply cap due to decreased transmission efficiency, thereby improving the operational efficiency of the water truck. Simultaneously, the use of the dustproof device reduces downtime caused by transmission structure maintenance, further enhancing overall work efficiency. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0030] A dustproof device for the electric tank opening of a water sprinkler truck, such as Figure 1 , 3 As shown: It includes a tank opening body 100 and a drive mechanism 200 disposed on the side of the tank opening body 100. The drive mechanism 200 includes a drive chamber 201 and a transmission chamber 202 disposed between the drive chamber 201 and the tank opening body 100. The transmission chamber 202 includes a rotatably disposed worm wheel 203 and a rotatably disposed worm. The teeth of the worm wheel 203 mesh with the teeth of the worm. The worm is indirectly connected to the drive chamber 201. When the drive chamber 201 is working, it can drive the worm to rotate in the transmission chamber 202. The rotation of the worm can drive the worm wheel 203 to rotate. The side wall of the water inlet cap 101 of the tank opening body 100 is fixedly connected to the outer side wall of the worm wheel 203. The rotation of the worm wheel 203 can drive the water inlet cap 101 to open and close.
[0031] Furthermore, movable rods 300 extend from both ends of the worm gear 203, such as... Figure 2As shown: The movable rod 300 is coaxially arranged with the worm gear 203. The rotation of the worm gear 203 can drive the movable rod 300 to rotate. Multiple dustproof plates 301 are also rotatably arranged between the two movable rods 300. The dustproof plates 301 have an arc-shaped structure, and each pair of adjacent dustproof plates 301 overlap each other. The upper surfaces of the drive chamber 201 and the water supply cover 101 are located on the same horizontal line. The multiple dustproof plates 301 are in a semi-circular structure. The edges of the two outermost dustproof plates 301 are connected to the top of the drive chamber 201 and the top of the water supply cover 101, respectively. In this way, the water supply cover 101 opens or closes synchronously with the rotation of the worm gear 203 during the opening and closing process, forming a dynamic sealing barrier on the top of the drive chamber 202.
[0032] Specifically, multiple protective panels have the same shape but different sizes, such as Figure 2 , 4 As shown: Dustproof plates 301 are arranged from smallest to largest from the inside out, and each dustproof plate 301 has a first extension plate 302 on its outer surface near the drive compartment 201, and a second extension plate 303 on its inner surface near the water supply cover 101. The largest protective plate connects to the top of the drive compartment 201, and the smallest protective plate connects to the top of the water supply cover 101. The first extension plate 302 and the second extension plate 303 form an overlapping limiting structure, thereby preventing adjacent dustproof plates 301 from falling off. When the working part of 201 indirectly drives the worm gear 203 to rotate, the worm gear 203 can synchronously drive the water supply cover 101 to open. During the opening process of the water supply cover 101, it can drive the smallest protective plate to rotate towards the drive chamber 201. During the rotation of the smallest protective plate, the second extension plate 303 on its inner surface can abut against the first extension plate 302 on the outer surface of the adjacent protective plate, thereby causing the adjacent protective plate to also rotate towards the drive chamber 201. That is, the semi-circular barrier formed by multiple protective plates gradually collapses as the worm gear 203 rotates.
[0033] Specifically, during the closing process of the water inlet cap 101, the smallest protective plate can be rotated toward the tank opening 100. In this way, the first extension plate 302 on the outer surface of the smallest protective plate can push the second extension plate 303 on the adjacent protective plate to rotate toward the tank opening 100. Multiple protective plates can be gradually reset, that is, the semi-circular barrier formed by multiple protective plates gradually unfolds as the worm gear 203 rotates.
[0034] Furthermore, the first extension plate 302 and the second extension plate 303 are arc-shaped strip structures, such as... Figure 4As shown: the arc-shaped strip structure of the extension plate can fully transmit force, and the cross-sections of the first extension plate 302 and the second extension plate 303 and the connected dustproof plate 301 are all L-shaped. In this way, when the first extension plate 302 and the second extension plate 303 on the adjacent dustproof plate 301 can be attached together, the protective structure composed of multiple protective plates becomes more stable.
[0035] Furthermore, each dustproof plate 301 has movable rings 304 at both ends, such as... Figure 2 As shown: The movable ring 304 can be sleeved on the movable rod 300. The movable ring 304 and the movable rod 300 are coaxially arranged and can rotate on the movable rod 300. The two movable rings 304 can provide rotational support for the protective plate. The end of the movable rod 300 is fixed to the end of the worm gear 203 by threaded connection. That is, the movable rod 300 can be quickly disassembled and assembled by the threaded structure, so that the protective plate can be quickly replaced. At the same time, the movable rod 300 can also be connected to the end of the worm gear 203 by snap-fit connection.
[0036] Furthermore, the end of the movable rod 300 also has a force-applying structure, such as... Figure 2 As shown: In this embodiment, the force-applying structure is set as a slot 305 structure, which makes it easy to rotate the movable rod 300 to remove it from the worm gear 203. At the same time, the force-applying structure can also be set as other structures that make it easy to rotate the movable rod 300.
[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
