Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology for ground parking lots, specifically a fire-fighting device for public ground parking lots. Background Technology

[0002] Above-ground parking lots are structures built on the ground for parking motor vehicles of various sizes. They mainly consist of parking spaces, passageways, ramps or mechanical lifts, entrances and exits, and shunting areas. Currently, above-ground parking lots typically only have fire hydrants or fire extinguishers installed. In the event of a vehicle fire, operators often do not have enough time to activate the fire hydrants or extinguishers, causing the fire to spread rapidly. Since vehicles are usually parked side-by-side in parking lots, a fire in one vehicle can ignite adjacent vehicles, eventually leading to the complete destruction of all vehicles in the parking lot. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a fire extinguishing device for public parking lots on the ground, solving the problem that existing ground parking lots lack a fire extinguishing device for timely extinguishing of burning vehicles.

[0004] To achieve the above objectives, the present invention provides a fire extinguishing device for a public parking lot, comprising a water supply pipe for installation in an external parking lot and connected to an external water supply device. Several drain pipes are arranged along the length of the water supply pipe. A housing is provided on the water supply pipe corresponding to each drain pipe position. The housing has an inlet hole for communication with the drain pipe. Water outlets are provided at both ends of the housing for communication with the inlet hole. The housing is equipped with a detection element for detecting and classifying the temperature and heat concentration location of the fire zone of an external burning vehicle. A driving element is provided on the housing corresponding to each of the two water outlet positions to drive the water outlets to swing so that their outlets are aligned with the heat concentration location. Each water outlet has an adjusting element for changing the spray angle and an opening / closing element for blocking or unblocking the water outlet. A control module is provided in the housing.

[0005] The advantages of adopting the above technical solution are as follows: The control module can control the opening / closing components, the driving components, and the detection components. Specifically, the control module periodically or in real-time activates the detection components to detect the temperature of vehicles in parking spaces. When the temperature at a certain point on the vehicle is too high, reaching the ignition temperature standard or exceeding a specified value, the detection components transmit a signal to the control module. The control module then activates the opening / closing components and the driving components. The driving components cause the water nozzles to swing, aligning their output holes with the concentrated heat location. The opening / closing components are designed to block or clear the water nozzles, allowing high-pressure water to be sprayed to the designated location for targeted fire suppression, thereby improving fire suppression efficiency and accuracy. The driving components allow the water nozzles to swing, enabling fire suppression of the entire vehicle or specific areas. Simultaneously, the swinging of the water nozzles while spraying water allows for circulating high-pressure water to the front and rear of the vehicle, increasing the fire suppression range. Furthermore, the control module in this technology can be centrally connected to external systems for centralized fire suppression. The system establishes a communication connection with the fire protection system or intelligent control platform to improve data transmission efficiency and data comparison and resolution efficiency. Simultaneously, when firefighting is required, the control module can communicate with an external centralized fire protection system or intelligent control platform to adjust the water output pressure of external fire water supply equipment, thereby enabling the water supply pipe to output high-pressure water. In the above technology, the water supply pipe can be installed on the parking lot wall or supported by columns, with the pipe installed on top of the support column, placing the water outlet at a high position in the parking space, thus improving firefighting efficiency. Furthermore, the above technology can reduce the number of drainage pipes and housings according to actual production needs, allowing one housing and its related structures to be aligned with multiple parking spaces, achieving firefighting coverage for multiple parking spaces, increasing the firefighting range, and reducing costs. Adjustable and driving components are used to adjust the spray angle and range of the water outlet, enabling one water outlet to cover multiple parking spaces, thereby increasing the firefighting range.

[0006] The invention further includes the following features: two swing grooves are provided at both ends of the housing corresponding to the two water outlet positions. Each swing groove is formed by a bottom groove on the bottom wall of the housing and a side groove on the outer wall of the housing, connected together. The radial cross-section of the swing groove is fan-shaped. A mating shaft is provided on both sides of the water outlet, rotatably mounted on the inner wall of the swing groove. A transition hole is provided at each of the two water outlet positions on the housing. The beginning of each water outlet is an output end for passing through the swing groove and aligning with external vehicles. A connecting hose is provided at the end of each water outlet for threaded connection with the end of the transition hole. The beginning of the transition hole is connected to the water inlet. A water outlet is provided along the length of the water outlet, with one end connected to the connecting hose and the other end extending to the output end face of the water outlet to form a water outlet. A first motor is provided in the swing groove, with a first gear plate at the output end of the first motor. A second gear plate is provided on the mating shaft, meshing with the first and second gear plates. The first motor is the driving component and is communicatively connected to the control module.

[0007] The advantages of adopting the above technical solution are as follows: When it is necessary to adjust the swing direction and amplitude of the water nozzle, the first motor starts and drives the first gear plate to rotate. The rotation of the first gear plate drives the second gear plate to rotate, which in turn drives the mating shaft to rotate. At this time, the mating shaft drives the water nozzle to swing in a fan shape in the swing groove, so that the water nozzle can quickly aim at the fire source and spray water. The above-mentioned technical setting improves the swing efficiency of the water nozzle and the efficiency of the water outlet aiming at the external fire source, thereby achieving efficient fire extinguishing. In the above-mentioned technology, the first motor is started and stopped by the control module. When the detection device detects a fire or excessively high temperature in a certain part of the vehicle, the control module can quickly control the swing of the water nozzle to aim at the fire source and spray high-pressure water to extinguish the fire. This improves fire extinguishing efficiency and enables targeted and centralized fire extinguishing, enhancing fire extinguishing accuracy. In the aforementioned technology, the swing groove is formed by connecting a bottom groove on the bottom wall of the casing and a side groove on the outer wall of the casing. The radial cross-section of the swing groove is fan-shaped, allowing the water outlet nozzle to swing within it. The fan-shaped arrangement of the two swing grooves increases the swing range and amplitude of the water outlet nozzle, thereby increasing the spray range and thus improving fire extinguishing efficiency and coverage. The connecting hose ensures that the water outlet and transition hole remain connected during the swing of the water outlet nozzle, ensuring proper water flow guidance and output. The first motor in the aforementioned technology is existing technology; therefore, its structure and function will not be described in detail.

[0008] The present invention further comprises: a third toothed disc is provided on both sides of the first toothed disc, and a fourth toothed disc is provided on both sides of the second toothed disc; the two third toothed discs and the two fourth toothed discs correspond one-to-one and are meshed; the diameter of the third toothed disc is larger than the diameter of the first toothed disc, and the diameter of the fourth toothed disc is smaller than the diameter of the second toothed disc.

[0009] The advantages of adopting the above technical solution are: the two third toothed discs and the two fourth toothed discs are one-to-one and meshed, which increases the force of the first motor driving the water outlet to swing, thereby improving the swing efficiency of the water outlet. In the above technology, the diameter of the third toothed disc is set to be larger than the diameter of the first toothed disc and the diameter of the fourth toothed disc is set to be smaller than the diameter of the second toothed disc, so as to realize the limiting of the second toothed disc by the combination of the two third toothed discs, thereby improving the connection strength between the first toothed disc and the second toothed disc, and avoiding the axial movement of the second toothed disc causing the first toothed disc and the second toothed disc to separate and cause meshing failure.

[0010] The present invention further comprises: a rotating shaft rotatably mounted on the inner peripheral wall of the outlet; the adjusting component includes an adjusting plate mounted on the rotating shaft and a second motor mounted on the outer wall of the outlet; a through hole communicating with the outlet and allowing the output end of the second motor to pass through; the output end of the second motor being connected to the rotating shaft; a sealing ring being fitted on the output end of the second motor; the outer peripheral wall of the sealing ring abutting against the inner peripheral wall of the through hole; and the second motor being communicatively connected to the control module.

[0011] The advantages of adopting the above technical solution are: when it is necessary to adjust the water spray direction of the nozzle, the control module controls the second motor to start, causing the output end of the second motor to drive the rotating shaft to rotate a certain distance along its axis. At this time, the adjusting plate swings in the water outlet, making the adjusting plate inclined relative to the radial section of the water outlet. At this time, the top of the adjusting plate partially abuts against the inner peripheral wall of the water outlet, so that when the water flows to the water outlet, it can be guided by the adjusting plate to change the direction of the water flow, thereby increasing the direction of the water flow sprayed from the nozzle, thereby increasing the fire extinguishing range, thereby improving the fire extinguishing efficiency and fire extinguishing accuracy of the sprayed water flow to the fire source; the above technology The adjustment plate can be changed according to the shape of the water outlet. That is, when the radial cross-section of the water outlet is square, the adjustment plate is rectangular, and when the radial cross-section of the water outlet is circular, the adjustment plate can be arc-shaped, thereby improving the compatibility between the two. The sealing ring in the above technology improves the sealing performance at the perforation, thereby preventing water from overflowing. At the same time, a sealed bearing can be fitted between the sealing ring and the output end of the second motor according to the rotation requirements of the rotating shaft and the frequency of use, thereby improving the smoothness of the rotation of the output end of the second motor in the perforation. The second motor in the above technology is a small motor and is existing technology, so its structure and function will not be described in detail.

[0012] The present invention further includes a setting where the swing direction of the adjusting plate is different from the swing direction of the water outlet.

[0013] The advantage of adopting the above technical solution is that the swing direction of the adjusting plate is different from that of the water outlet. That is, when the water outlet swings in a fan shape towards the front and rear ends of the housing, the adjusting plate will not swing in a fan shape towards the front and rear ends of the housing. Instead, the adjusting plate will swing in a fan shape from left to right. This increases the direction of the water flow from the water outlet, thereby increasing the fire extinguishing range and improving the fire extinguishing efficiency and accuracy of the sprayed water flow on the fire source.

[0014] The present invention further includes: an electric valve for sealing or clearing the transition holes is provided at each of the two transition hole positions in the housing, the electric valve being the opening and closing element, and the electric valve being communicatively connected to the control module.

[0015] The advantages of adopting the above technical solution are: the control module controls the opening and closing of the electric valve in the above technology, thereby realizing the spraying and closing of the water outlet, thereby improving the fire extinguishing rate. At the same time, the efficient response of the electric valve reduces the fire extinguishing time, ensuring that the vehicle can be quickly extinguished when it first catches fire. The electric valve in the above technology is existing technology, so its structure and function will not be described in detail.

[0016] The present invention further includes the following configuration: the detection component includes several infrared temperature sensors disposed at the bottom of the housing, the output ends of the infrared temperature sensors are all detection ends for aligning with external vehicles, and the infrared temperature sensors are all configured to communicate with the control module.

[0017] The advantages of adopting the above technical solution are: In this technology, the overall temperature of the vehicle is detected using an infrared temperature sensor. The activation and deactivation of the infrared temperature sensor can be controlled by a control module, thereby achieving timed activation or real-time detection. In this technology, the detection end of each infrared temperature sensor is pointed towards the outside vehicle, meaning each infrared temperature sensor detection end is set towards the ground of the parking space. Because the infrared temperature sensor is located above the parking space, the tilt angle of the infrared temperature sensor detection end relative to the bottom of the housing can be adjusted during installation to ensure that the infrared temperature sensor can illuminate the vehicle. The arrangement of multiple infrared temperature sensors allows each sensor to detect the vehicle temperature. Furthermore, the infrared temperature sensors can be installed separately according to detection requirements; that is, the infrared rays emitted by the detection ends of some infrared temperature sensors can cover and encompass the front half of the parking space, while those of other infrared temperature sensors... The infrared rays emitted by the detection end can cover and encompass the rear half of the parking space, thus achieving overall temperature detection of the vehicle. In the above technology, after several infrared temperature sensors detect the temperature, they convert the temperature data into signals and send them to the control module. The control module then sends the signals to an external intelligent control platform, which compares the temperature data with normal temperature data. If an error is found, a signal is sent to the control module, which then controls the opening and closing components and the drive components, so that the water nozzle is aimed at the hottest fire source for extinguishing. If the distance between the infrared temperature sensor and the parking space is too high, the infrared temperature sensor can be replaced with a long-range infrared temperature detector. If the accuracy of the infrared temperature sensor is affected by the special ground surface of the parking lot, an infrared imaging sensor can be used instead during installation and production, increasing costs to improve detection accuracy and detection range. The infrared temperature sensor in the above technology is existing technology, so its structure and function will not be described in detail.

[0018] The present invention further comprises: a plurality of the infrared temperature sensors arranged along the length of the housing at the bottom of the housing.

[0019] The advantages of adopting the above technical solution are: In this technology, several infrared temperature sensors are arranged along the length of the housing at the bottom, allowing them to be aligned with the vehicle. This combination of sensors enables comprehensive vehicle detection, improving the detection range and accuracy. It ensures that each infrared temperature sensor can detect a portion of the vehicle, thus achieving overall vehicle detection. Furthermore, the infrared temperature sensors can be digitally arranged according to their arrangement order, from one end of the housing to the other. The arrangement of numbers 1 to n facilitates the control module in controlling the swing amplitude of the water outlet. For example, when the temperature data fed back by infrared temperature sensor No. 8 is too high, the control module can control the water outlet near infrared temperature sensor No. 8 to swing quickly to the side of infrared temperature sensor No. 8, thereby achieving high-precision fire extinguishing of the water flow from the water outlet to the fire source. To achieve the above technical objective, several infrared temperature sensors can be arranged in pairs along the length of the shell on both sides of the two water outlets. At the same time, the detection ends of the two infrared temperature sensors in each group are staggered. This technical setting enables the water outlet to swing with high precision and high efficiency. Attached Figure Description
