Description

Technical Field

[0001] This application relates to the technical field of sports venue facilities, and in particular to the spray mechanism of a spray-type sports stadium track water testing device. Background Technology

[0002] The purpose of water testing on stadium running tracks is to check the drainage performance of the track surface, ensuring that water does not accumulate on the track during rainy weather, thus affecting the safety and performance of athletes. Water testing can reveal whether there are low-lying areas or problems with poor drainage. Currently, water testing of stadium running tracks is usually conducted using manual spraying or fixed sprinklers.

[0003] However, these methods have significant drawbacks. First, manual spraying, due to variations in operator skill, is prone to uneven spraying, making it difficult to ensure that every square meter of the track receives adequate water. Second, fixed sprinkler heads cannot adjust the spray height, making it impossible to conduct adaptability tests on tracks at different heights, affecting the comprehensiveness and accuracy of the tests. Finally, traditional sprinkler equipment is generally inefficient, not only time-consuming and labor-intensive but also requiring frequent maintenance after long-term use, increasing maintenance costs.

[0006] By adopting the above technical solution, the device is moved to the runway area to be sprayed by the moving wheels, and the flow rate of the spray liquid is adjusted by the control valve to control the spray liquid to be sprayed evenly from the nozzle. The spray pattern can be adjusted by adjusting the angle of the nozzle according to the adjustment component to simulate the shape of the runway, ensuring that the spray liquid can evenly and completely cover the entire runway area.

[0007] As a preferred embodiment, the conveying pipe passes through the storage tank and is located inside the storage tank. A quick-connect fitting is provided at the connection between the conveying pipe and the connecting pipe. The conveying pipe is a rigid pipe and is made of a rigid material.

[0008] By adopting the above technical solution, not only is durability enhanced, but the stability and sealing of the pipeline are also ensured, facilitating the introduction of the spray liquid from the storage tank into the connecting pipe. Quick-connect couplings are installed at the junction of the delivery pipeline and the connecting pipe, making the connection between the two more convenient and faster, eliminating the need for frequent disassembly and installation. The nozzles deliver the spray liquid to the work site through the connecting pipe, achieving efficient spraying operations.

[0009] As a preferred embodiment, the end of the connecting pipe that is away from the delivery pipe is configured as a telescopic pipe, and a constant pressure valve is provided at the connection point between the connecting pipe and the nozzle.

[0010] By adopting the above technical solution, the telescopic pipe is installed at the end of the connecting pipe away from the delivery pipe, allowing the connecting pipe to extend and retract with the movement of the adjusting component, thereby adapting to the length changes of the adjusting component during movement. Simultaneously, a constant pressure valve is installed at the connection between the connecting pipe and the nozzle, maintaining stable water pressure within the connecting pipe and ensuring that the spray liquid is evenly sprayed through the nozzle at a constant pressure.

[0011] As a preferred embodiment, the adjustment assembly includes a fixed frame connected to the front end face of the frame, a transverse slider slidably connected to the fixed frame, a racetrack-shaped slide rail disposed on the front end face of the transverse slider, a rack fixedly disposed at the middle position of the front end face of the transverse slider, a gear meshing with the rack and connected to the connecting shaft, a guide slider fixedly disposed on the inner side of the gear and adapted to the racetrack-shaped slide rail, a vertical slider disposed on the end of the connecting shaft away from the gear, a support frame fixedly disposed on the front end face of the fixed frame, a vertical slide groove disposed on the inner side of the support frame and adapted to the vertical slider, and a push-pull cylinder fixedly disposed on one side of the fixed frame and connected to the transverse slider.

[0012] As a preferred embodiment, a sealed bearing is provided at the connection between the connecting shaft and the vertical slider, and one end of the connecting shaft passes through the support frame and is fixedly connected to the nozzle.

[0014] As a preferred embodiment, the telescopic shaft of the push-pull cylinder is fixedly connected to one side of the transverse slider, and the outer periphery of the transverse slider is tangent to the inner wall of the fixed frame.

[0015] By adopting the above technical solution, the telescopic shaft of the push-pull cylinder is responsible for pushing the horizontal slider to move in the horizontal direction. It is fixedly connected to one side of the horizontal slider, so that the extension and retraction of the telescopic shaft can drive the horizontal slider to reciprocate along the inner wall of the fixed frame.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] Please refer to the details. Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a spray mechanism for a spray-type gymnasium track water testing device. The device includes a frame 1, casters 10 positioned at the four corners of the lower end face of the frame 1, a storage tank 2 fixedly mounted on one end of the upper end face of the frame 1, an inlet pipe 21 connected to the storage tank 2, a delivery pipe 31 connected to one side of the upper end face of the storage tank 2, a connecting pipe 32 connected to the other end of the delivery pipe 31, a control valve 311 mounted on the delivery pipe 31, a nozzle 321 mounted on the other end of the connecting pipe 32, a connecting shaft 521 connected to the inner side of the nozzle 321, and an adjustment assembly for adjusting the connecting shaft 521. The inlet pipe 21 is externally connected to a municipal water supply system. In this invention, during use, the device is moved to the runway area to be sprayed using the casters 10. The flow rate of the spray liquid is adjusted by the control valve 311, controlling the spray liquid to be sprayed evenly from the nozzle 321. The spray pattern can be adjusted according to the angle of the nozzle 321 by the adjustment assembly to simulate the shape of the runway, ensuring that the spray liquid can evenly and comprehensively cover the entire runway area.

[0023] Please refer to the details. Figure 1 and Figure 2The delivery pipe 31 runs through the storage tank 2 and is located within the inner cavity of the storage tank 2. A quick-connect coupling is provided at the connection point between the delivery pipe 31 and the connecting pipe 32. The delivery pipe 31 is made of rigid material, which not only enhances durability but also ensures the stability and sealing of the pipe, facilitating the introduction of the spray liquid from the storage tank 2 into the connecting pipe 32. The quick-connect coupling is installed at the connection point between the delivery pipe 31 and the connecting pipe 32, making the connection between the two more convenient and quick, eliminating the need for frequent disassembly and installation. The nozzle 321 delivers the spray liquid to the work site through the connecting pipe 32, achieving efficient spraying operations.

[0024] Please refer to the details. Figure 1 and Figure 2 The end of the connecting pipe 32 furthest from the delivery pipe 31 is configured as a telescopic pipe, and a constant pressure valve is installed at the connection point between the connecting pipe 32 and the nozzle 321. The telescopic pipe at the end of the connecting pipe 32 furthest from the delivery pipe 31 allows the connecting pipe 32 to extend and retract with the movement of the adjusting component, thus adapting to changes in the length of the adjusting component during movement. Simultaneously, the constant pressure valve at the connection point maintains stable water pressure within the connecting pipe 32, ensuring that the spraying liquid is uniformly sprayed through the nozzle 321 at a constant pressure. In summary, the combined effect of the telescopic pipe and the constant pressure valve not only ensures the flexible movement of the connecting pipe 32 to adapt to the movement of the adjusting component but also maintains a stable supply and uniform spraying of the spraying liquid, enabling the entire system to maintain efficient and uniform spraying operations even when the position of the adjusting component changes.

[0025] Please refer to the details. Figure 2 , Figure 3 and Figure 4The adjustment assembly includes a fixed frame 41 fixedly mounted on the front end face of the frame 1 and connected to it; a transverse slider 42 slidably connected to the fixed frame 41; a racetrack-shaped slide 421 mounted on the front end face of the transverse slider 42; a rack 51 fixedly mounted at the middle position of the front end face of the transverse slider 42; a gear 52 meshing with the rack 51 and connected to the connecting shaft 521; a guide slider 522 fixedly mounted inside the gear 52 and adapted to the racetrack-shaped slide 421; and a guide slider 522 mounted on the connecting shaft 521 away from the gear 52. The system includes a vertical slider 5211, a support frame 6 fixedly mounted on the front end of the fixed frame 41, a vertical slide groove 61 adapted to the vertical slider 5211 and mounted on the inner side of the support frame 6, and a push-pull cylinder 7 fixedly mounted on one side of the fixed frame 41 and connected to the horizontal slider 42. A sealed bearing is provided at the connection between the connecting shaft 521 and the vertical slider 5211, and one end of the connecting shaft 521 passes through the support frame 6 and is fixedly connected to the nozzle 321. The support frame 6 is provided with a sliding hole adapted to the connecting shaft 521. The fixed frame 41 is fixed on the frame 1, providing a stable foundation for the entire system. The push-pull cylinder 7 serves as the driving force source, pushing the transverse slider 42 to achieve precise horizontal displacement. The transverse slider 42 moves horizontally on the fixed frame 41, and its front end racetrack-shaped slide 421 guides it to move along a specific trajectory. The rack 51 fixed in the middle of the front end face of the transverse slider 42 meshes with the gear 52, transmitting force and driving the gear 52 to rotate. The gear 52 not only drives the connecting shaft 521 to rotate, but also slides in the guide slider 522 installed on its inner side and adapted to the racetrack-shaped slide 421, achieving horizontal positioning. The connecting shaft 521 is connected to the vertical slider 5211 fixed at its other end. The vertical slider 5211 moves in the vertical groove 61 inside the support frame 6, maintaining rotation while adjusting its vertical position. The support frame 6 is fixed on the front end face of the fixed frame 41, and the inner vertical groove 61 is adapted to the vertical slider 5211. The working principle is as follows: When the push-pull cylinder 7 is working, it pushes the horizontal slider 42 to move horizontally in the inner cavity of the fixed frame 41, thereby driving the rack 51 fixed on it to move synchronously; the rack 51 meshes with the gear 52, causing the gear 52 to rotate, and through the sliding of the guide slider 522 on it in the racetrack-shaped slide 421 and the movement of the vertical slider 5211 in the vertical slide groove 61, it ensures that the connecting shaft 521 can perform precise horizontal and vertical compound motion on the racetrack-shaped slide, thereby driving the nozzle 321 connected to the connecting shaft 521 to reciprocate according to the preset trajectory, so as to achieve uniform distribution of water spray.

[0026] Please refer to the details. Figure 1 and Figure 2The telescopic shaft of the push-pull cylinder 7 is fixedly connected to one side of the transverse slider 42, and the outer periphery of the transverse slider 42 is tangential to the inner wall of the fixed frame 41. The telescopic shaft of the push-pull cylinder 7 is responsible for pushing the transverse slider 42 to move in the horizontal direction. By being fixedly connected to one side of the transverse slider 42, the extension and retraction of the telescopic shaft can drive the transverse slider 42 to reciprocate along the inner wall of the fixed frame 41.

[0027] Please refer to the details. Figure 3 and Figure 4 The vertical slide 61 is set along the height of the support frame 6 and is connected to the sliding hole. When the nozzle 321 needs to perform a racetrack-like reciprocating motion, the connecting shaft 521 moves up and down in the sliding hole. At the same time, under the guidance of the vertical slide 61, the vertical slider 5211 is also driven to slide up and down along a fixed vertical path. This achieves precise guidance of the nozzle 321 and reciprocating motion in the horizontal direction.

[0028] The implementation principle of the spray mechanism of the spray-type gymnasium track water testing device in this application embodiment is as follows: In use, the device is moved to the track area to be sprayed by the moving wheel 10. The flow rate of the spray liquid is adjusted by the control valve 311 to control the spray liquid to be sprayed evenly from the nozzle 321. When the push-pull cylinder 7 is working, it pushes the horizontal slider 42 to move horizontally in the inner cavity of the fixed frame 41, thereby driving the rack 51 fixed on it to move synchronously. The rack 51 meshes with the gear 52, causing the gear 52 to rotate. Through the sliding of the guide slider 522 on it in the track-shaped slide 421 and the movement of the vertical slider 5211 in the vertical slide groove 61, it is ensured that the connecting shaft 521 can perform precise horizontal and vertical compound motion on the track-shaped slide, thereby driving the nozzle 321 connected to the connecting shaft 521 to reciprocate according to the preset trajectory to achieve uniform distribution of water spray.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
