Description

TECHNICAL FIELD

[0001] The utility model relates to a ventilation equipment, especially an iron tower manufacturing workshop ventilation equipment. BACKGROUND

[0002] In the industrial production workshop, the ventilation equipment as the important facility of guaranteeing the safe operation environment, generally adopts the structure form such as wall-mounted fan, ceiling type ventilation fan and mobile industrial fan. This kind of equipment mainly realizes the basic ventilation function through mechanical switch or simple gear adjustment, and the conventional application scene includes welding fume discharge, spraying waste gas collection, high-temperature area heat dissipation and dust centralized treatment operation environment. When the traditional ventilation system operates, the operator needs to manually open and close the equipment according to the visual environmental condition, adjusts the three-grade wind speed through the knob or adjusts the air outlet angle by means of the universal joint, wherein the centralized ventilation pipeline system adopts the centrifugal fan to pump the polluted air to the purification device for treatment, and the local ventilation relies on the axial flow fan for directional air supply. In the continuous production process, the worker needs to regularly patrol the equipment operating state, and manually intervenes and adjusts according to the workshop temperature and humidity meter, dust concentration visual inspection and other simple means.

[0003] However, the existing ventilation equipment generally has the defect of insufficient intelligence. The fixed speed operation mode is difficult to cope with the dynamic change of the pollution source distribution in the workshop, and no sensor is configured to detect the specific area pollution concentration exceeding the standard, so that the ventilation equipment receives the signal and automatically increases the fan speed of the corresponding area, resulting in the hysteresis of emergency response. At the same time, the mechanical type wind direction adjusting mechanism needs to be manually operated frequently, cannot automatically adjust the air supply angle according to the change of environmental parameters, and is easy to cause the coexistence of ventilation blind area and air flow redundant area. This passive ventilation mode not only increases the manual monitoring cost, but also causes energy waste due to continuous full-power operation, especially in the multi-process alternating operation scene, the fixed wind speed may cause secondary pollution of clean area air. In addition, the control mode lacking of data linkage is difficult to realize the optimization of the overall ventilation efficiency of the workshop, and affects the effect of occupational health protection. UTILITY MODEL CONTENTS

[0004] In view of the defects of the prior art, the utility model provides an iron tower manufacturing workshop ventilation equipment which can better ventilate the interior of the workshop.

[0005] To achieve the above purpose, the utility model technical scheme is as follows: an iron tower manufacturing workshop ventilation equipment, comprising a shell and a fan arranged in the shell, further comprising a control system for controlling the fan and a temperature sensor for transmitting signals to the control system, the temperature sensor is arranged on the shell and is used to confirm where the temperature is higher in the up, down, left and right directions of the shell to the control system, and the fan turns to the place where the temperature is higher under the control of the control system.

[0006] The utility model discloses beneficial effect is: through the linkage of temperature sensor and control system, realized the directional air supply of fan to high temperature area, effectively promoted the heat dissipation efficiency. Temperature sensor passes through the temperature comparison of multipoint position, can dynamic identification workshop in different direction heat source distribution, makes the fan can real -time adjustment air supply direction, avoids the local heat dissipation blind area of traditional fixed type air supply. As a preferred mode, can adopt multiple group distributed temperature sensor array arrangement in different direction of shell, through signal processing module to multiple temperature signal difference comparison, control system according to the maximum temperature difference value drive fan rotates to specified angle, to form accurate directional airflow control. The structure scheme realizes the initiative perception and response of temperature gradient, makes the equipment have the ability of self -adaptation environmental change.

[0007] Further, it further includes a rotating assembly for driving the temperature sensor to rotate, the rotating assembly includes a rotating motor, a rotating disc arranged at the front end of the rotating motor and driven by the rotating motor, and a transmission rod for transmission, one end of the transmission rod is fixed with the temperature sensor, and the other end is hinged to the eccentric position of the rotating disc; The shell is provided with a limiting groove for converting the rotation of the transmission rod and the rotating disc on one side into the circumferential swinging of the end of the transmission rod fixed with the temperature sensor.

[0008] Through the cooperation of the eccentric transmission structure and the limiting groove, the reciprocating swinging scanning function of the temperature sensor is realized. The eccentric hinge of the transmission rod converts the rotary motion into arc swinging, and the guiding action of the limiting groove makes the sensor can periodically scan and detect the surrounding environment along the set track. As a preferred mode, the limiting groove can be designed as an arc-shaped slide with a specific curvature, a layer of low-friction coefficient material is arranged on the inner wall of the limiting groove, a rolling bearing is installed at the end of the transmission rod to contact the slide, which not only ensures smooth movement but also reduces mechanical wear. The structure makes the sensor can cover a certain fan-shaped detection area, significantly improves the spatial resolution of temperature sampling.

[0009] Further, the limiting groove is gradually tapered from the hinging place of the transmission rod and the rotating disc to the hole diameter where the transmission rod is fixed with the temperature sensor, and a gap is formed between the limiting groove and the movement path of the transmission rod, and an elastic limiting piece is arranged on the inner periphery wall of the limiting groove on the side where the transmission rod is fixed with the temperature sensor.

[0010] The tapered limiting groove design combined with the elastic limiting piece effectively solves the vibration impact problem in the swinging process of the transmission rod. The tapered structure forms a progressive motion damping through spatial constraint, and cooperates with the deformation buffer of the elastic material to gradually absorb mechanical impact energy. As a preferred mode, the elastic limiting piece can adopt a multi-layer silicon rubber gasket structure, and a hemispherical protrusion is arranged at the end to contact the transmission rod, which can ensure the necessary constraint force while allowing small displacement compensation. The structure can accurately limit the swinging amplitude of the transmission rod, and can also avoid the fatigue damage of components caused by rigid impact, prolonging the service life of the equipment.

[0011] Further, the swing assembly for driving the fan to adjust the wind direction is further included, the swing assembly includes a swing motor controlled by the control system, a vertical shaft driven by the swing motor to rotate, and an eccentric shaft with an axis intersecting with the axis of the vertical shaft to form an inclination angle, and the fan is fixed on the eccentric shaft.

[0012] The three-dimensional adjustment capability of the fan blowing angle is realized through the double-shaft linkage mechanism. The vertical shaft provides the basic rotation freedom, and the space included angle formed by the eccentric shaft enables the fan to produce the pitch angle change. As a preferred mode, the universal joint is adopted between the eccentric shaft and the vertical shaft, and the angle encoder is arranged at the connection position, so that the closed-loop control is realized through the feedback of the actual deflection angle of the fan. The structure enables the fan to not only rotate horizontally, but also adjust the pitch angle according to the heat source distribution, so as to form the three-dimensional blowing mode, and is particularly suitable for the workshop environment with multiple heat sources.

[0013] Further, the moving assembly for driving the fan to move forward and backward in the shell is further included, the moving assembly includes a fixed table, the swing assembly is arranged on the fixed table, moving blocks are arranged on both sides of the fixed table, a threaded rod driven by a moving motor is transmissionally matched with the center of each moving block, and a sliding groove is arranged in the shell and used for sliding movement of the moving blocks.

[0014] The double-threaded rod synchronous driving structure realizes the accurate linear displacement control of the fan group. The cooperation between the moving blocks and the sliding groove guarantees the straightness of the movement track, and avoids the yawing error generated by the traditional single-shaft driving. As a preferred mode, the reverse thread design is adopted for the threaded rods on both sides, and the same-shaft double-output motor is matched to realize the bidirectional synchronous movement, and the linear guide rail and the ball sliding block assembly are arranged in the sliding groove, so as to ensure the smooth movement in the moving process. The structure enables the fan to be finely adjusted in position within a certain range, and in combination with the wind speed adjustment function, forms the multi-dimensional ventilation parameter combination control, and significantly improves the adaptability under complex working conditions.
