Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, specifically a heat dissipation type fall protection alarm device. Background Technology

[0002] Forklifts are commonly used industrial vehicles for handling, loading, unloading, and stacking goods. Safety is increasingly important in forklift operations, especially when fully loaded, as there is a risk of the forks accidentally falling or dropping. Currently, alarm devices are primarily installed on the fork carriage. These devices utilize a controller, position sensors to monitor the forklift mast's descent acceleration, and changes in the height and position of the forks. When the acceleration or position sensor detects an anomaly, the controller immediately triggers a high-decibel alarm, accompanied by flashing lights, to alert the operator and surrounding personnel to take safety precautions.

[0003] Existing alarm devices integrate all components into a closed enclosure. Due to their compact internal structure and lack of ventilation openings, air circulation is poor. Since alarm devices generate heat during operation, especially in high-temperature environments or during prolonged continuous operation, heat accumulation can cause the internal temperature to rise. Excessive temperatures not only affect the performance and lifespan of electronic components but may also trigger false alarms or device malfunctions, thereby reducing the reliability and safety of the alarm device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat-dissipating fall protection alarm device that can improve its heat dissipation efficiency, significantly enhance the device's reliability and safety, and also prevent dust and moisture.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat-dissipating fall-prevention alarm device includes a housing, a second ventilation opening on the top of the housing, and a third ventilation opening on the side wall of the housing; it also includes a heat dissipation assembly, which includes a suction fan and a radiator installed inside the housing, the suction fan being arranged opposite to the second ventilation opening, and the radiator being arranged opposite to the third ventilation opening.

[0007] In a further embodiment, a horizontal plate is installed inside the housing to divide its internal space into an upper cavity and a lower cavity; the suction fan is located in the upper cavity, and a partition plate is vertically installed in the middle of the lower cavity to divide the lower cavity into left and right halves; one end of the radiator extends into a third ventilation opening.

[0008] In a further embodiment, the radiator includes a heat dissipation fin assembly and an annular partition plate built into the middle of the heat dissipation fin assembly, with an exhaust fan installed in the inner cavity of the annular partition plate.

[0009] In a further embodiment, ventilation holes are provided on the side wall of the annular partition plate.

[0010] In a further embodiment, a protective assembly is installed on the top of the enclosure. The protective assembly includes a fixing plate fixed to the enclosure, and a first ventilation opening communicating with the second ventilation opening is opened in the middle of the fixing plate. A moisture-proof and dust-proof plate is installed in the middle of the first ventilation opening.

[0011] In a further embodiment, the moisture-proof and dust-proof board is detachably connected to the fixed plate via a connector; the connector includes a base plate fixed to the fixed plate, an mounting cylinder is mounted on the base plate, a groove is provided on the outer side wall of the mounting cylinder, and a movable plate is provided laterally inside the mounting cylinder, with both ends of the movable plate extending outward and passing through the groove, allowing it to move along the length of the groove; an elastic element is connected to the upper end face of the movable plate, and an insertion rod that inserts into the moisture-proof and dust-proof board is fixed to the lower end face.

[0012] In a further embodiment, the moisture-proof and dust-proof plate includes a mounting ring and a silicone drying plate and a filter screen installed inside the mounting ring and overlapping each other; a slot is provided on the outer wall of the mounting ring; one end of the connector is connected to the slot on the mounting ring.

[0013] A further embodiment also includes a sensor, which is mounted inside the housing via a substrate and has its detection end extending to the outside of the housing; the sensor includes an acceleration sensor and a position sensor.

[0014] In a further embodiment, an installation plate or magnetic suction plate is installed on the outer wall of the housing for installation.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The fall alarm device of this application has a heat dissipation component installed inside the enclosure, thereby realizing the flow of hot and cold air between the inside and outside and achieving heat dissipation. Specifically, the suction fan accelerates the introduction of cold air from the outside into the enclosure, accelerating the airflow inside the enclosure, and then the heat dissipates the hot air inside through the radiator.

[0017] In addition, installing exhaust fan blades in the heat dissipation fin assembly can accelerate airflow and disperse it to improve heat dissipation efficiency.

[0018] 2. This application installs a protective component at the air inlet (i.e., the second ventilation opening) of the enclosure, wherein the moisture-proof and dust-proof plate can protect the external cold air from dust and moisture, thereby protecting the performance of the electronic components inside the enclosure.

[0019] 3. This application divides the internal space of the enclosure into two independent air ducts by setting up horizontal plates and partition plates, so as to avoid the convection of cold and hot air and the recirculation of hot air. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This embodiment of a heat dissipation type fall protection alarm device includes a housing 1, the top of which has a second ventilation opening 101 and the side wall of which has a third ventilation opening 102; it also includes a heat dissipation component 6, which includes a suction fan 601 and a radiator installed inside the housing, the suction fan being disposed opposite to the second ventilation opening 101 and the radiator being disposed opposite to the third ventilation opening 102.

[0029] Specifically, a third ventilation opening 102 is provided on each of the opposite side walls of the enclosure, and two radiators are also provided. The exhaust fan 601 introduces cool air from outside into the enclosure through the second ventilation opening 101, while the radiators exhaust the heat inside the enclosure to the outside through the third ventilation opening 102, thus forming an air circulation and greatly reducing the temperature inside the enclosure.

[0030] like Figure 2 As shown, a horizontal plate 7 is installed inside the housing 1, dividing its internal space into an upper chamber and a lower chamber. The sensor and the suction fan are located in the upper chamber, and several ventilation holes are opened on the horizontal plate 7 to connect the air inside the upper and lower chambers. A partition plate 8 is vertically installed in the middle of the lower chamber, dividing the lower chamber into left and right halves. A heat sink is installed in each of the left and right halves, and one end of the heat sink extends into the third ventilation port 102 on the same side to exhaust the heat inside the housing to the outside of the housing.

[0031] Furthermore, by setting up the horizontal plate 7 and the partition plate, the space inside the box 1 can be divided into two independent air ducts to avoid the convection of cold and hot air and the recirculation of hot air.

[0032] like Figure 3 As shown, the radiator includes a heat dissipation fin assembly 602 and an annular partition plate 603 built into the middle of the heat dissipation fin assembly 602. An exhaust fan 604 is installed in the inner cavity of the annular partition plate 603. Ventilation holes are provided on the side wall of the annular partition plate 602 for air circulation. The exhaust fan 604 can accelerate the airflow and air velocity, and at the same time, make the airflow more evenly distributed on the heat dissipation fin assembly, improve the heat dissipation efficiency, and then exhaust it to the outside of the casing through the third vent 102.

[0033] The intake fan and exhaust fan in this application are both existing products, both being small structures installed on the side wall of the enclosure and connected to an external power outlet for power supply. The intake fan is mainly used to draw in cool air from outside the enclosure, while the exhaust fan is used to expel hot air from inside the enclosure for cooling, thus achieving the functions of ventilation and heat dissipation.

[0034] like Figure 4 As shown, a protective assembly 9 is installed on the top of the housing 1. The protective assembly 9 includes a fixing plate 901 fixed to the housing. A first ventilation opening 902, communicating with the second ventilation opening 101, is opened in the middle of the fixing plate 901. A moisture-proof and dust-proof plate 903 is installed in the middle of the first ventilation opening 902. Under the action of the suction fan, external cold air is accelerated and introduced through the first ventilation opening 902. After being filtered and dried by the moisture-proof and dust-proof plate 903, it enters the interior of the housing 1 through the second ventilation opening 101. The moisture-proof and dust-proof plate 903 can prevent dust and moisture from entering the external cold air, avoiding any impact on components such as sensors.

[0035] In this embodiment, the moisture-proof and dust-proof board 903 is detachably connected to the fixing plate 901 via a connector 904, thereby facilitating the cleaning or replacement of the moisture-proof and dust-proof board 903; the structure of the connector 904 is as follows: Figure 5 As shown, it includes a base plate 9045 fixedly connected to a fixed plate 901. An mounting cylinder 9041 is mounted on the base plate 9045. A sliding groove is formed on the outer wall of the mounting cylinder 9041. A movable plate 9042 is transversely arranged inside the mounting cylinder 9041. Both ends of the movable plate 9042 extend outwards and pass through the sliding groove, allowing it to move along the length of the sliding groove. An elastic element 9043 is connected to the upper end face of the movable plate 9042, and an insertion rod 9044, which is inserted into a moisture-proof and dust-proof plate 903, is fixed to the lower end face. In this embodiment, the elastic element is preferably a spring, with one end connected to the movable plate 9042 and the other end connected to the top of the mounting cylinder 9041. The movement of the movable plate 9042 can cause the spring to extend or shorten.

[0036] During installation, align the slot of the mounting ring 9033 on the moisture-proof and dust-proof plate 903 with the position of the connector. Then, adjust the position of the insert rod 9044 on the connector 904 so that its outer end engages with the slot. Due to the spring force, the two are connected. When removing the moisture-proof and dust-proof plate 903, manually move the moving plate 9042 along the mounting cylinder 9041 towards the elastic member 9043 to compress the spring, causing the insert rod 9044 to retract and separate from the mounting ring 9033, thereby removing the moisture-proof and dust-proof plate 903 for cleaning, repair, or replacement.

[0037] like Figure 6 As shown, the moisture-proof and dust-proof plate 903 includes a mounting ring 9033 and a silica gel drying plate 9031 and a filter screen 9032 installed inside the mounting ring 9033 and overlapping each other; the outer wall of the mounting ring 9033 has a slot; one end of the connector 904 is connected to the slot on the mounting ring 9033. The silica gel drying plate 9031 is an existing product, which achieves efficient moisture absorption through its porous structure and chemical stability, and is widely used in industrial, food, and electronics fields. After external cold air is filtered to remove particulate matter or dust by the filter screen 9032, it is then dehumidified by the silica gel drying plate 9031, so that the cold air that finally enters the chamber is dry and clean, protecting the performance and safety of electronic components such as sensors.

[0038] In this embodiment, the device also includes sensors. These sensors are mounted inside the housing 1 via a base plate 2, with their detection ends extending to the outside of the housing. Specifically, mounting holes are provided on the side wall of the housing's front, and the sensor's detection end protrudes through these holes for detection. The sensors include an acceleration sensor 3 and a position sensor 4. An alarm, such as a buzzer alarm, is also mounted on the base plate 2. The acceleration sensor 3 monitors changes in the acceleration of the forklift mast, and the position sensor 4 monitors changes in the height and position of the forks. When either the acceleration sensor 3 or the position sensor 4 detects an abnormality, it sends a signal to the controller, which immediately triggers the buzzer alarm, emitting a high-decibel alarm sound and flashing lights to alert the operator and surrounding personnel to safety.

[0039] The controller, sensors, and alarms are all existing components in existing alarm devices. This application only improves the structure of the enclosure and does not involve improvements to electronic components or connection methods. Specifically, the signal output terminals of the accelerometer 3 and the position sensor 4 are electrically connected to the buzzer alarm through the controller.

[0040] To facilitate the installation of this device on a forklift or other components, a mounting plate 5 or a magnetic suction plate is installed on the outer side wall of the housing 1.

[0041] The device described in this application can be installed in any location or place requiring monitoring. For example, the device can be mounted on the top of a forklift frame using a mounting plate 5 and bolts. When installed in other locations where it is inconvenient to drill threaded holes, it can be installed using a magnetic suction plate, thereby enhancing its versatility.
