Description

Technical Field

[0001] The present invention relates to the technical field of linear heaters, and in particular to an intelligent linear heater. Background Art

[0002] In the application scenarios of linear heaters, the installation stability, operation reliability and fault warning capabilities of the equipment have always been the focus of industry attention. Traditional linear heaters lack effective installation stability and operation monitoring mechanisms. When loose installation and operation failures (large vibrations) occur, timely monitoring and warnings cannot be achieved, resulting in the failure to detect and eliminate potential faults in a timely manner, increasing the risk of equipment operation. Even if some linear heaters are equipped with basic monitoring functions, their technical limitations are still prominent: on the one hand, the equipment is highly dependent on external power supply. When encountering emergencies such as power grid failures and temporary power outages, built-in alarms and other safety modules will fail simultaneously, and cannot meet the needs of all-weather safety protection. On the other hand, existing monitoring functions generally require manual activation. The traditional design lacks an intelligent linkage mechanism to prevent forgotten operations. After completing the installation and commissioning of the equipment, the staff often forget to turn on the monitoring function due to process omissions or operational inertia, which has defects and deficiencies. Summary of the Invention

[0005] Furthermore, a warning groove is provided on the right side of the top surface of the installation status monitoring shell, and a plug-in groove is provided on the right side of the bottom end of the inner end of the warning groove, and the plug-in groove is a U-shaped groove structure; a left-side conductive block is embedded in the axial center of the semicircular structure on the left side of the inner end of the plug-in groove; a right-side conductive block is embedded in the axial center of the semicircular structure on the right side of the inner end of the plug-in groove.

[0006] Furthermore, a nylon drawstring is fitted inside the socket, with both ends of the nylon drawstring extending from the top open end of the socket and located inside the warning socket. A button battery is also fitted inside the socket, with the positive and negative ends of the button battery contacting the left conductive block and the right conductive block respectively, and the button battery is in contact with the nylon drawstring.

[0007] Furthermore, a group of buzzers is fixedly installed on the left side of the bottom surface of the inner end of the warning groove; one pin of the buzzer is connected to the annular conductive sheet through a wire; and the other pin of the buzzer is connected to the left conductive block through a wire.

[0008] Furthermore, the right conductive block is connected to the annular conductive insert through a wire; when the iron conductive ball contacts the annular conductive insert and the annular conductive sheet, the buzzer is in a power-on state.

[0009] Furthermore, a closing plate is provided above the installation status monitoring shell, and a plug-in hole penetrating through the bottom end surface is provided on the top surface of the closing plate adjacent to the four edge angles, and a fixing bolt is inserted into the four plug-in holes; four threaded blind holes are provided on the top surface of the installation status monitoring shell; when the fixing bolts are threadedly fixed and installed in the threaded blind holes, the bottom end surface of the closing plate contacts the top surface of the installation status monitoring shell, and at this time the monitoring slot and the warning slot are both covered and closed by the closing plate.

[0010] Furthermore, a spring receiving groove with a circular groove structure is provided on the top surface of the closing plate relative to the axial center of the monitoring groove, and a pressure hole with a circular hole is provided on the axial center of the inner bottom surface of the spring receiving groove, and the pressure hole passes through the bottom end surface of the closing plate; a pressure column is inserted into the pressure hole.

[0011] Furthermore, a limiting pressure plate with a circular plate structure is fixedly installed at the axial center of the top surface of the pressure column. The limiting pressure plate is slidably plugged into the spring receiving groove, and the bottom end surface of the limiting pressure plate is fixedly connected to the bottom surface of the inner end of the spring receiving groove through a reset spring; when the reset spring is in the natural state, the top end surface of the limiting pressure plate is higher than the top end surface of the closing plate, and at this time, the bottom end surface of the pressure column is higher than the iron conductive ball.

[0012] Furthermore, a pressure plate is rotatably installed on the left edge of the top end surface of the closing plate, and a baffle is fixedly installed on the right edge of the bottom end surface of the pressure plate; when the bottom end surface of the pressure plate contacts the top end surface of the closing plate, the baffle corresponds to the position of a ventilation port of the linear heater, and at this time, the bottom end surface of the pressure plate presses against the limiting pressure plate, and the bottom end surface of the pressing column presses against the top of the iron conductive ball.

[0013] The present invention provides an intelligent linear heater, which has the following beneficial effects:

[0014] The present invention adopts a double mechanical clamping design. During the installation of the linear heater, the bottom end surface of the pressure plate maintains close contact with the top surface of the closing plate. The upper and lower coordinated clamping structures are formed by the pressure column and the magnet block to firmly limit the iron conductive ball in the monitoring slot. This design utilizes the dual effects of mechanical pressure and magnetic adsorption to effectively suppress the rolling displacement of the iron conductive ball during the installation operation, thereby avoiding false alarm triggering due to accidental touch from the root, and significantly improving the stability and reliability of the installation process.

[0015] The present invention is based on a mandatory operation mechanism of the ventilation port linkage to achieve physical constraint-type anti-forgetting. Since the pressure plate and the ventilation port of the linear heater form a positional correspondence, when the equipment is installed, the staff must rotate and unfold the pressure plate along the closing plate to remove the baffle from blocking the ventilation port to avoid affecting the subsequent operation of the linear heater. This structural design that must be unfolded forces the operator to complete the key steps through mechanical linkage to avoid missing the pressure plate unfolding operation due to human negligence, which not only ensures the normal operation of the equipment ventilation and heat dissipation, but also establishes mandatory constraints on operational norms from a structural level.

[0016] After the pressure plate of the present invention is unfolded, the compressed return spring rebounds quickly, pushing the limit pressure plate to drive the pressure column to move upward along the pressure hole, thereby releasing the mechanical lock on the iron conductive ball. At this time, the temporary storage groove of the magnet block forms a double limit through the curved surface fitting design and the strong magnetic attraction force, which can effectively offset the slight vibration during normal operation of the equipment, ensuring that the iron conductive ball remains stable in a non-fault state. When the equipment fails and the vibration amplitude suddenly increases or the installation becomes loose and causes position displacement, the iron conductive ball breaks through the constraints of the magnetic force and the storage groove under the action of inertia or gravity, rolls along the monitoring groove until it contacts the annular conductive insert and the annular conductive sheet at the same time, instantly connecting the internal circuit of the installation status monitoring shell, and triggering the buzzer to emit a high-decibel warning sound. This intelligent mechanism realizes dynamic monitoring of abnormal vibration and installation displacement of the equipment, ensuring timely early warning of potential fault hazards.

[0017] The present invention adopts button batteries as independent power supply components, completely getting rid of dependence on external power sources. Even in sudden situations such as power outages, it can still continue to provide stable power to the alarm circuit, ensuring the all-weather reliability of the warning function and meeting the stringent requirements of safety protection scenarios. In addition, the present invention is easy to maintain. By simply removing the fixing bolts in the threaded blind hole, the closing plate and the monitoring shell can be quickly separated, completely exposing the monitoring slot and the warning slot, making it convenient for staff to reset the iron conductive ball to the temporary storage slot; when replacing the button battery, only the nylon draw strap needs to be pulled to remove the battery from the socket without damage, greatly reducing the technical threshold and time cost of maintenance operations.

[0033] Example: Please refer to Figures 1 to 9 :

[0034] The present invention proposes an intelligent linear heater, comprising: a linear heater 1. As a widely used heating equipment, the core technical principle of the linear heater 1 is to generate heat through a linear heating element and realize space heating by air convection or radiation. In view of the fact that its technical solution has been generally mastered by those skilled in the art, it will not be repeated here. The top surface of the chassis of the linear heater 1 is provided with an installation status monitoring shell 2. The top surface of the installation status monitoring shell 2 is provided with an installation groove 201 relative to the four edge angles.

[0035] Among them, a closing plate 3 is provided above the installation status monitoring shell 2, and a plug hole 305 is provided on the top surface of the closing plate 3 adjacent to the four edge angles, and a fixing bolt 301 is inserted in the four plug holes 305; four threaded blind holes 209 are provided on the top surface of the installation status monitoring shell 2; when the fixing bolts 301 are threadedly fixed and installed with the threaded blind holes 209, the bottom surface of the closing plate 3 contacts the top surface of the installation status monitoring shell 2. At this time, the monitoring groove 203 and the warning groove 2010 are both covered and closed by the closing plate 3; a spring receiving groove 308 with a circular groove structure is provided on the top surface of the closing plate 3 relative to the axial center of the monitoring groove 203, and a pressing hole 309 with a circular hole is provided on the axial center of the bottom surface of the inner end of the spring receiving groove 308, and the pressing hole 309 passes through the bottom surface of the closing plate 3; a pressing column 30 is inserted inside the pressing hole 309 6. A limiting pressure plate 304 with a circular plate structure is fixedly installed on the axial center of the top surface of the pressure column 306. The limiting pressure plate 304 is slidably plugged into the spring receiving groove 308. The bottom end surface of the limiting pressure plate 304 is fixedly connected to the bottom surface of the inner end of the spring receiving groove 308 through a return spring 307. In the natural state of the return spring 307, the top surface of the limiting pressure plate 304 is higher than the top surface of the closing plate 3, and at this time the bottom end surface of the pressure column 306 is higher than the iron conductive Ball 208; a pressure plate 302 is rotatably installed on the left edge of the top end surface of the closing plate 3, and a baffle 303 is fixedly installed on the right edge of the bottom end surface of the pressure plate 302; when the bottom end surface of the pressure plate 302 contacts the top end surface of the closing plate 3, the baffle 303 corresponds to the position of a ventilation port of the linear heater 1, and at this time, the bottom end surface of the pressure plate 302 presses against the limiting pressure plate 304, and the bottom end surface of the pressing column 306 presses against the top of the iron conductive ball 208.

[0036] The working principle of this embodiment is as follows:

[0037] During the installation of the linear heater 1, the bottom surface of the pressing plate 302 is always in contact with the top surface of the closing plate 3, so that the pressing column 306 and the magnet block 206 can jointly limit and clamp the iron conductive ball 208 to prevent it from rolling in the monitoring slot 203, thereby avoiding false alarms;

[0038] When the bottom surface of the pressing plate 302 contacts the top surface of the closing plate 3, the baffle 303 corresponds to the position of a ventilation port of the linear heater 1. Therefore, after the linear heater 1 is installed, in order to prevent the linear heater 1 from affecting its subsequent operation, the staff will rotate and unfold the pressing plate 302 along the closing plate 3 so that the baffle 303 no longer blocks the ventilation port of the linear heater 1. This structural setting implements a mandatory operation for the staff to avoid forgetting to rotate and unfold the pressing plate 302 after the linear heater 1 is installed.

[0039] When the pressure plate 302 is rotated and expanded, the return spring 307 in the compressed state quickly returns to its original position and rebounds without the pressure of the pressure plate 302, pushing the limit pressure plate 304 upward, thereby simultaneously driving the pressure column 306 to move upward along the pressure hole 309, so that the pressure column 306 no longer presses the iron conductive ball 208, thereby releasing the position lock of the iron conductive ball 208;

[0040] Because the iron conductive ball 208 is placed in the temporary storage groove 207 of the magnet block 206, the temporary storage groove 207 and the iron conductive ball 208 are fitted together and the magnet block 206 magnetically attracts the iron conductive ball 208, so that the iron conductive ball 208 is double-positioned and limited in position, so that the slight vibration generated during the normal operation of the linear heater 1 will not cause the iron conductive ball 208 to escape from the temporary storage groove 207; when the linear heater 1 fails and the vibration is greatly aggravated or the linear heater 1 is loosely installed, causing the linear heater 1 to fall and deviate in position, at this time When the iron conductive ball 208 vibrates greatly or the linear heater 1 is tilted, it will break through the constraints of the magnetic force and the temporary storage groove 207 due to the inertial force or gravity, and the iron conductive ball 208 will break away from the temporary storage groove 207 and roll along the monitoring groove 203. When the iron conductive ball 208 rolls along the monitoring groove 203 until it contacts the annular conductive insert 204 and the annular conductive sheet 205 at the same time, the internal circuit of the installation status monitoring housing 2 is connected, and the buzzer 2011 is in the power-on state, which will emit a high-decibel buzzer, thereby providing a warning to the user and prompting timely maintenance.

[0041] Furthermore, the present invention does not require an external power supply. It uses a button battery 2013 as a power supply component and is not affected by factors such as power outages. This ensures that when the linear heater 1 fails or is loosely installed, it can stably serve as a warning, achieving intelligence and meeting the application requirements of safety protection.

[0042] When it is necessary to reset the iron conductive ball 208 or replace the button battery 2013, the fixing bolt 301 can be removed along the threaded blind hole 209 by a tool, so that the closing plate 3 can be separated from the installation status monitoring shell 2 to expose the monitoring slot 203 and the warning slot 2010 that are blocked by it, so that the staff can replace the iron conductive ball 208 in the temporary storage slot 207 of the magnet block 206 to reset the position of the iron conductive ball 208. When replacing the button battery 2013, the staff can grasp the ends of the nylon drawstring 2012 and pull it upwards, thereby synchronously driving the button battery 2013 to be pulled out of the plug-in slot 2016 through the nylon drawstring 2012 to facilitate the replacement of the new button battery 2013.
