Description

Technical Field

[0001] This invention relates to the field of hole tracking technology, specifically a fire sprinkler hole tracking system. Background Technology

[0002] In the field of building fire protection engineering construction, the core procedures for fire sprinkler pipe opening, point location tracking, and pipe distance measurement are the core procedures for sprinkler system installation. The accuracy of point location, the quality of opening, and the accuracy of distance measurement directly determine the flatness of sprinkler head installation, the sprinkler coverage effect, and the overall quality of fire protection construction acceptance.

[0003] Currently, most fire sprinkler system construction sites in China still use traditional methods such as plumb line calibration, manual measurement with tape measures, and simple positioning tools. This process requires repeated measurement, calibration, and adjustment, resulting in cumbersome procedures, low efficiency, and a high dependence on the experience of construction personnel, making it prone to human error. Common problems include sprinkler hole eccentricity, point misalignment, and improper pipe length matching. These issues not only affect the aesthetics of the ceiling decoration but also lead to insufficient water coverage of the sprinkler system, creating fire safety hazards. Therefore, this invention proposes a fire sprinkler hole tracking system. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a fire sprinkler hole tracking system, which solves the problems of inconvenient operation and inaccurate positioning of existing hole tracking systems.

[0005] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: a fire sprinkler hole tracking system, comprising a metal clamping housing, a ball joint type laser positioning assembly, a laser positioning housing, a knurled locking knob, and a power supply assembly; The bottom of the metal clamping housing is detachably threaded with a flange, and wrench flanges are symmetrically arranged on both sides of the bottom of the flange. The wrench flanges integrate the dual functions of disassembly and assembly, force application, and hole opening and hooking. The laser positioning housing includes a constraint front head, a sealed rear head, and a switch; the bottom of the ball joint laser positioning assembly is rotatably embedded inside the constraint front head, and a central hole is opened at the center of the bottom of the flange, and the laser emitting end of the ball joint laser positioning assembly is correspondingly embedded in the central hole; The knurled locking knob passes through the laser emitting end of the ball joint laser positioning assembly and is threadedly connected to the constraint front end. The power supply component is detachably embedded inside the laser positioning housing; the ball joint laser positioning component, the laser positioning housing, and the knurled locking knob are integrally sealed and embedded inside the metal clamping housing via a flange. The system adopts a fully enclosed structure, with electronic components and power supply components all internally arranged, providing overall waterproof and dustproof sealed protection.

[0006] Preferably, the top of the metal clamping housing is provided with a threaded adapter, which is a pipe diameter adaptable structure that can match various specifications of spray pipes to achieve adaptable and fixed installation of the equipment.

[0007] Preferably, the constraint front end forms a radial limiting constraint on the ball-head universal joint laser positioning component, and the laser emitting end of the ball-head universal joint laser positioning component can achieve a small-angle adaptive deflection to compensate for and correct the concentricity deviation of the laser emission, thereby ensuring the positioning accuracy of the hole tracking.

[0008] Preferably, when the knurled locking knob is tightened, it can compress and lock the ball joint type laser positioning component, so that after the laser angle and position are corrected, the laser positioning structure can be fixedly positioned without offset.

[0009] Preferably, the sealed rear end head is threadedly embedded in the bottom of the laser positioning housing, the bottom of the power supply component is in close contact with the upper surface of the sealed rear end head, and the power switch is movably embedded in the center of the sealed rear end head, thus realizing a sealed button installation structure.

[0010] Preferably, the power supply component is a built-in lithium battery pack, which has a long battery life and can meet the continuous operation conditions of the construction site for a whole day with a single charge.

[0011] Preferably, this system has a two-way operation function. When the equipment is installed upright, the fire sprinkler hole positioning operation can be completed by laser projection. When the equipment is used upside down, the wrench flange can be hooked to the edge of the wall opening, and the length measurement operation of the suspended sprinkler pipe can be completed in conjunction with the upward-projected laser.

[0012] Preferably, the fully enclosed packaging structure enables the equipment to be waterproof and dustproof, making it suitable for complex construction sites with high humidity and dust levels, and supporting continuous operation throughout the entire construction process.

[0013] In summary, the technical effects and advantages of this invention are as follows: In this invention, a laser positioning housing is detachably assembled inside a metal clamping housing. A ball-head universal joint laser positioning component is assembled at the front end of the laser positioning housing by constraining the rotation of the front end head. Relying on the deflectable structure of the ball-head universal joint, the ball-head universal joint laser positioning component can achieve small-angle adaptive deflection, effectively compensating for and correcting the concentricity deviation of the laser emission, improving the problems of laser offset and inaccurate tracking in traditional equipment, significantly improving the positioning accuracy of fire sprinkler hole openings, effectively reducing the probability of rework caused by construction misalignment and hole eccentricity, and significantly improving the construction qualification rate and work efficiency.

[0014] Meanwhile, the metal clamping housing features a threaded structure at the rear end, allowing for compatibility with adapters and various spray pipe specifications on construction sites, significantly improving the equipment's versatility and adaptability to different scenarios. The laser positioning housing houses a removable, electrically embedded power supply component, which is sealed within the housing via a sealed rear end. This built-in power supply structure greatly enhances the equipment's endurance, enabling continuous 24-hour construction on a single charge, reducing the frequency of equipment start-ups, shutdowns, and charging, and effectively ensuring construction continuity.

[0015] In addition, the present invention adopts a layered nested fully enclosed protective structure, in which a metal clamping shell encloses the laser positioning shell, and the laser positioning shell encloses the power supply components. Combined with the overall sealed encapsulation design, the device has excellent waterproof and dustproof performance, which can perfectly adapt to the complex and harsh working conditions of construction sites with dampness and dust, effectively avoid equipment failure and laser positioning deviation caused by environmental factors, and significantly improve the operational stability and service life of the device.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] refer to Figures 1-5 The fire sprinkler opening tracking system shown below has the following specific embodiment: Example 1 This embodiment includes the specific assembly and implementation structure for adapting equipment to multiple pipe diameters, with the core function of quickly connecting and fixing spray pipes of different specifications, as detailed below: The main load-bearing structure of this system is a metal clamping housing 1. The metal clamping housing 1 adopts a fixed-diameter integrated structure, which has high overall structural strength and low deformation probability, ensuring the overall stability of the equipment after installation. The top of the metal clamping housing 1 is integrally provided with a threaded adapter joint. This threaded adapter joint serves as the core adapting structure and can be matched with various specifications of spray pipes through threaded connection.

[0019] During assembly and use, the metal clamping housing 1 serves as the outer load-bearing base, with the laser positioning housing 4 detachably nested inside, resulting in a compact and stable overall assembly structure. Compared to traditional integrated pipe diameter limiting structures, this embodiment utilizes a combination structure of a threaded adapter and the metal clamping housing 1, eliminating the limitation of single-diameter compatibility. The threaded connection method allows for convenient assembly and disassembly, precise alignment, and eliminates the need to replace the main equipment. Different sprinkler pipes can be fixedly installed simply by matching the corresponding adapter accessories. This structure, relying on the rigid support of the metal clamping housing 1 and the detachable adaptability of the threaded adapter, significantly improves the equipment's versatility, enabling it to adapt to the laying and positioning of fire sprinkler pipes of various sizes commonly found on construction sites.

[0020] Example 2 This embodiment includes a two-way functional implementation structure for the wrench flange, realizing the dual functions of equipment disassembly and assembly force application and hole opening and suspension, as detailed below: The bottom of the metal clamping housing 1 of the equipment is detachably connected to a flange 2 by a thread. The flange 2 serves as a bottom sealing and functional load-bearing component. The left and right sides of its bottom are symmetrically integrally formed with wrench flanges 201. The two wrench flanges 201 are symmetrically arranged and the force is balanced, supporting two construction conditions.

[0021] In the forward assembly condition of the equipment, the flange 2 is sealed and assembled at the bottom of the metal clamping housing 1. The construction personnel can directly hold the wrench flange 201 as the force fulcrum to tighten, disassemble, and fix the flange 2 and the whole equipment, replacing the traditional auxiliary wrench tool and simplifying the equipment installation and disassembly process.

[0022] When performing distance measurement on suspended pipelines, the entire device can be inverted, and the wrench flange 201 at the bottom of flange 2 can be engaged with the edge of the opening in the wall or ceiling. The symmetrically arranged wrench flanges 201 form a stable hanging support structure, allowing the device to be securely suspended at the opening position without manual hand-holding. This structure, relying on the load-bearing foundation of flange 2, achieves a dual function for the wrench flange 201, combining the functions of applying force during equipment assembly and inverted suspension positioning. It effectively adapts to the dual construction needs of spray nozzle opening location and suspended pipeline distance measurement, resulting in a higher degree of functional integration.

[0023] Example 3 This embodiment includes a deviation compensation and locking positioning structure for the ball joint type laser positioning assembly to achieve precise laser tracking, as detailed below: A constraint front end head 401 is fixedly installed at the front end of the laser positioning housing 4 of the equipment. The bottom of the ball-head universal joint laser positioning assembly 3 is rotatably embedded in the internal cavity of the constraint front end head 401. Through the cavity limiting effect of the constraint front end head 401, radial and axial constraints are formed on the ball-head universal joint laser positioning assembly 3, limiting it to only small-angle adaptive deflection and restricting large swings to ensure the stability of the positioning reference. At the same time, the knurled locking knob 5 passes through the laser emitting end of the ball-head universal joint laser positioning assembly 3, and the tail of the knurled locking knob 5 forms a threaded assembly structure with the constraint front end head 401.

[0024] Before positioning, the deflection angle of the ball-head universal joint laser positioning component 3 can be finely adjusted. Its small deflection characteristic can be used to compensate for the laser emission concentricity deviation caused by equipment assembly errors and mechanical tolerances, correct the laser offset problem, and ensure the precise alignment of the laser projection reference.

[0025] After the laser angle and position are corrected, the knurled locking knob 5 is turned to axially press the ball-head universal joint laser positioning component 3, achieving complete locking and fixation of the component. After locking, the ball-head universal joint laser positioning component 3 has no offset or shaking, and the laser emission angle remains stable. By constraining the front end 401 and the knurled locking knob 5 through a combined limiting and locking structure, an adjustable and lockable precise positioning effect is achieved.

[0026] Example 4 This embodiment includes a specific implementation structure for the equipment to be fully sealed, waterproof, dustproof, and with long battery life, adaptable to complex construction site conditions, as detailed below: The laser positioning housing 4 has a removable cavity for housing power supply component 6. The bottom of the laser positioning housing 4 is threaded with a sealing rear end head 402. The upper end face of the sealing rear end head 402 is tightly attached to the bottom of the power supply component 6, forming an axial compression and sealing fixation of the power supply component 6. At the same time, the center of the sealing rear end head 402 is movably fitted with a switch 403, which achieves bottom sealing while ensuring normal operation of the button.

[0027] This equipment adopts a layered nested sealed structure. The outer side is wrapped and fixed by the metal clamping shell 1, and the inner side is completely wrapped by the laser positioning shell 4, which in turn completely encloses the power supply component 6 and internal circuit components. With the flange 2 and the sealing rear end head 402 providing all-round sealing, the equipment forms a fully sealed encapsulated structure with excellent waterproof and dustproof performance. It can effectively resist the corrosion of moisture and dust at the construction site and avoid equipment failure and laser positioning deviation.

[0028] Meanwhile, the built-in power supply component 6 can stably power the equipment, and the battery capacity is adapted to the construction needs. After a single power-on charge, it can meet the continuous operation of the construction site for a whole day without the need for frequent start-stop charging, which greatly reduces the frequency of operation and ensures the continuous and efficient progress of fire sprinkler hole opening and distance measurement procedures, perfectly adapting to various complex and harsh construction environments.

[0029] Working principle of this invention: This invention is a fire sprinkler pipe opening and positioning system. The system relies on a nested sealing structure and a ball joint adjustable laser positioning structure, combined with a detachable built-in power supply, to achieve the overall functions of precise opening and positioning of fire sprinkler pipes, distance measurement of suspended pipe length, multi-diameter adaptation, and stable operation under complex working conditions.

[0030] When the equipment is working, it first matches the corresponding specification of the spray pipe through the threaded adapter at the top of the metal clamp housing 1. The overall assembly and fixation of the equipment is quickly completed by using the thread. It can adapt to the installation needs of various pipe diameters on the construction site, and is easy to assemble and highly versatile.

[0031] During the equipment positioning operation, the front end of the laser positioning housing 4 constrains the front end head 401 to limit the ball joint laser positioning component 3, so that the laser positioning component can only slightly adapt to the angle deflection. The staff can fine-tune the laser angle according to the on-site benchmark deviation to compensate for the laser emission concentricity error caused by mechanical assembly in real time. After the correction is completed, the knurled locking knob 5 is tightened to form a compression lock on the ball joint laser positioning component 3, so that the laser emission angle remains constant and without deviation, ensuring the accuracy of spray hole tracking and effectively reducing the problems of construction eccentricity, misalignment and rework.

[0032] This equipment operates on a two-way principle. In the forward installation state, the laser is projected vertically downward to complete the pipe opening and positioning operation. In the inverted state, the wrench flanges 201 symmetrically set on both sides of the flange 2 are used to hang the equipment at the opening, so as to suspend and fix the equipment in the air. In conjunction with the upward projection of the laser, the suspended spray pipe distance measurement operation is completed, realizing the dual process of finding the point and measuring the distance in one integrated manner.

[0033] Meanwhile, the equipment adopts a layered, fully enclosed protective structure, forming an integral sealed cavity with a metal clamping housing 1, a laser positioning housing 4, a sealed rear end head 402, and a flange 2. This completely isolates the power supply component 6 and internal circuitry, providing excellent waterproof and dustproof capabilities, making it suitable for complex environments with high humidity and dust levels on construction sites. The built-in power supply component 6 enables stable power supply over extended periods, with a single charge sufficient for continuous operation throughout the day, effectively improving the overall efficiency and stability of fire sprinkler systems.

[0034] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
