Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a sensor protection device. Background Technology

[0002] Stress sensors for coal sheds are key devices for monitoring deformation in steel grid structures. They are typically installed at various points on the steel structure and protected by enclosures to prevent damage from the external environment. However, existing enclosure installation methods, such as bolt fixing, snap-fit ​​structures, welding, or adhesive bonding, all have significant drawbacks. For example, bolt fixing and snap-fit ​​fixing require tools, involve cumbersome installation steps, and frequent disassembly can lead to thread wear or snap-fit ​​breakage. Welding is complex and may damage the steel structure, while also posing safety hazards for hot work at heights. Adhesive bonding is prone to failure due to adhesive aging and makes subsequent maintenance difficult. Furthermore, existing enclosures have poor versatility and are difficult to adapt to various sensor models and mounting rod specifications. Therefore, there is an urgent need to develop a new sensor protection device that is easy to install, highly versatile, and easy to maintain. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sensor protection device that solves the problems of inconvenient installation, low versatility and safety hazards of existing sensor protection devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sensor protection device for covering a rod on which a sensor is mounted includes a cover and two sets of fixing devices. The cover includes a cover body and at least two locking blocks. The locking blocks are fixedly connected to the upper and lower ends of the cover body, and when the cover body covers the rod, it forms an inner cavity with the rod to accommodate the sensor.

[0006] The fixing device is a strip-shaped structure with a width adapted to the locking block. The fixing device surrounds and fits the rod body and is locked in a closed state, so that the cover has a fixed state fixed to the rod body.

[0007] The locking block, which is fixedly connected to the upper end of the cover body, includes a locking block body and a blocking part. The locking block body and the blocking part are fixedly connected. When in the fixed state, the blocking part is used to prevent the cover body from displacing relative to the fixing device.

[0008] Furthermore, the lower surface of the blocking part is fixedly connected to the upper surface of the card block body. The blocking part has a blocking surface. When in the fixed state, the blocking surface contacts the upper surface of the fixing device to prevent the cover body from moving downward.

[0009] Furthermore, the blocking part is provided with a dovetail groove through which the fixing device passes, and the fixing strap is movably connected to the dovetail groove.

[0010] Furthermore, the contact surface between the cover body and the rod body is an arc surface.

[0011] Furthermore, the housing body is provided with a through hole for the sensor wiring to pass through, and the through hole is located on the lower surface of the housing body.

[0012] Furthermore, the fixing device is a steel cable tie.

[0013] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0014] This utility model provides a sensor protection device, including a cover and two sets of fixing devices. The cover includes a cover body and a locking block. The locking block is fixedly connected to the upper and lower ends of the cover body. When the cover body covers the rod on which the sensor is installed, it forms an inner cavity that can accommodate the sensor. The fixing device is strip-shaped and adapted to the width of the locking block. Then, the fixing device cooperates with the locking block and surrounds and fits the rod body and locks it into a closed state, so that the cover has a fixed state fixed to the rod body. At this time, the inner cavity corresponds to the position of the sensor. The cover effectively isolates the sensor from the threats and damage that the external environment may cause to the sensor, providing a physical barrier for the internal sensor. Furthermore, the locking block fixedly connected to the upper end of the cover body includes a locking block body and a blocking part. When in the fixed state, the blocking part can prevent the cover body from shifting relative to the fixing device under its own weight or the action of outdoor vibration and impact. This device secures the casing using only two sets of fixing devices and locking blocks. Whether for initial installation or subsequent disassembly and maintenance, the operation is simple and tool-free, improving work efficiency. Furthermore, it avoids physical damage such as drilling to fix the casing, causing no damage to the device itself or the rod, achieving completely non-destructive installation. This not only protects the integrity of the rod but also allows the sensor protection device to be reused after disassembly. In addition, the mechanical locking mechanism eliminates the need for welding or other open-flame operations during installation, avoiding safety hazards caused by high temperatures and sparks, making the entire installation process safer and more reliable.

[0028] As attached Figure 1 To be continued Figure 3 As shown, a sensor protection device is used to cover a rod 3 on which a sensor is installed. It includes a cover 1 and two sets of fixing devices 2. The cover 1 includes a cover body 11 and at least two locking blocks 12. The locking blocks 12 are fixedly connected to the upper and lower ends of the cover body 11. When the cover body 11 covers the rod 3, it forms an inner cavity 111 that can accommodate the sensor. The inner cavity 111 corresponds to the position of the sensor when the cover 1 is installed. The fixing devices 2 are strip-shaped structures with a width adapted to the locking blocks 12. The two sets of fixing devices 2 are respectively engaged with the locking blocks 12 on both sides of the cover body 11. After the fixing devices 2 are locked and fitted around the rod 3, they are in a closed state. At this time, the cover 1 is fixed to the rod 3 under the action of the fixing devices 2, ensuring that it will not loosen or fall off under vibration or other external forces. The cover 1 effectively isolates the sensor from potential damage caused by the external environment, providing a physical barrier for the internal sensor. Furthermore, the locking block 12, which is fixedly connected to the upper end of the housing body 11, includes a locking block body 121 and a blocking part 122. The locking block body 121 and the blocking part 122 are fixedly connected. When in a fixed state, the blocking part 122 is used to prevent the housing body 11 from displacing relative to the fixing device 2. It can constrain the housing body 11 in the vertical direction, enhance the connection stability of the sensor protection device, and prevent the housing body 11 from loosening and falling off from the fixing device 2 under its own weight or outdoor vibration and impact.

[0029] Specifically, the fixing device 2 can be a cable tie, clamp, nylon rope or steel wire rope with a locking mechanism, etc., which can be selected and adjusted by those skilled in the art according to the actual application, product requirements and installation requirements. Preferably, the fixing device 2 has a redundant length design, which can be locked at different positions to accommodate rods 3 of different diameters, thereby improving the versatility of the sensor protection device. Furthermore, the shape of the housing body 11 can be a cuboid, cube, cylinder, etc. with an inner cavity 111, and is not limited here. In addition, the locking method of the fixing device 2 can be a buckle, bolt and nut fastening, etc., so that the fixing device 2 is connected to the locking block 12 and locked around and attached to the rod 3 to prevent the connection from loosening due to external forces and other factors, and to ensure the overall stability of the sensor protection device. Furthermore, the blocking part 122 can be a block structure that is fixedly connected at an angle to the upper side of the card block body 121, or it can be a dovetail groove through which the fixing device 2 passes, or the blocking part 122 can be a magnetic structure when the fixing device 2 is a steel structure or other magnetically attractable material, etc., all of which can achieve the limiting function of the cover body 11.

[0030] This utility model's sensor protection device first places the cover 1 over the sensor, then uses two sets of fixing devices 2 to engage and lock with the locking blocks 12, securing the cover 1 to the rod 3. This provides good stability and simplifies operation for both initial installation and subsequent disassembly and maintenance, requiring no tools and improving work efficiency. Furthermore, it avoids physical damage such as drilling to fix the cover 1, causing no damage to the sensor protection device itself or the rod 3, achieving completely non-destructive installation. This not only protects the integrity of the rod 3 but also allows the sensor protection device to be reused after disassembly. Additionally, the mechanical locking mechanism of the cover 1 eliminates the need for welding or other open-flame operations, preventing safety hazards caused by high temperatures and sparks, making the entire installation process safer and more reliable. This expands the applicability of the sensor protection device, allowing it to be used in more complex environments. Furthermore, the blocking part 122, when in a fixed state, prevents the cover body 11 from shifting relative to the fixing device 2 under its own weight or outdoor vibration and impact, further enhancing the installation stability of the sensor protection device.

[0031] In some embodiments of this utility model, as shown in the appendix Figure 2 and attached Figure 3As shown, the lower surface of the blocking part 122 is fixedly connected to the upper surface of the block body 121, and the blocking part 122 is at an angle to the block body 121, preferably a right angle. The blocking part 122 has a blocking surface 1221. When it is in a fixed state, the blocking surface 1221 contacts the upper surface of the fixing device 2. When the cover body 11 has a downward tendency, the contact surface between the blocking part 122 and the fixing device 2 generates a force that prevents the cover body 11 from moving, directly blocking the fixing device 2 to play a limiting role, thereby preventing the cover body 11 from displacing relative to the rod 3.

[0032] In some embodiments of this utility model, as shown in the appendix Figure 4 and attached Figure 5 As shown, the blocking part 122 is provided with a dovetail groove 1222 through which the fixing device 2 passes, and the fixing device 2 is movably connected to the dovetail groove 1222. Specifically, when the fixing device 2 passes through the dovetail groove 1222, the inclined sides of the dovetail groove 1222 can restrict the vertical displacement of the fixing device 2, thus allowing it to move only within the defined groove track of the dovetail groove 1222. That is, when the cover 1 is subjected to its own weight or outdoor vibration and impact, the dovetail groove 1222 will lock the fixing device 2, and the inner wall of the dovetail groove 1222 will generate a blocking force on the fixing device 2, thereby preventing the cover 1 from moving downward relative to the rod 3. Through the above-mentioned limiting effect, the stability of the cover 1 after fixing is effectively improved. Furthermore, the dovetail groove 1222 can also guide the installation position of the fixing device 2. When installing the sensor protection device, the user can first install the fixing device 2 in the dovetail groove 1222 at the upper end of the cover body 11 for movable connection, and then fix the fixing device 2 and the cover 1 to the sensor on the rod 3. Lock the fixing device 2 on the upper side of the cover 1 for preliminary positioning, and then use another set of fixing devices 2 in conjunction with the locking block 12 at the lower end of the cover body 11 to achieve complete locking of the cover 1. In this way, during installation, the user can hold the cover 1 with one hand and operate the fixing device 2 at the same time with the other hand. Only one person can complete the installation of the sensor protection device, reducing the manpower requirements for the installation of the sensor protection device and improving the installation efficiency.

[0033] In some embodiments of this utility model, as shown in the appendix Figure 1 As shown, since most of the rods 3 are cylindrical, the contact surface 112 between the cover body 11 and the rod 3 is an arc surface to match the surface shape of the rod 3, thereby enhancing the contact effect between the sensor protection device and the rod 3, avoiding gaps, and achieving a tight fit. This effectively blocks external dust, rainwater, impurities, etc. from entering, better protecting the sensor on the rod 3, and improving protection performance and reliability.

[0034] In some embodiments of this utility model, as shown in the appendix Figure 1As shown, the housing body 11 is provided with a through hole 113 for the sensor wiring to pass through, so as to ensure the normal transmission of sensor signals or power supply. The through hole 113 is located on the lower surface of the housing body 11, so that dust, rainwater, impurities and other external things are less likely to enter the housing 1 from the top or side and come into contact with the sensor, reducing the risk of sensor damage and extending its service life.

[0035] In some embodiments of this utility model, the fixing device 2 is a steel cable tie, which can be flexibly adjusted and tightened according to the thickness of the rod 3. It can adapt to different specifications of rod 3 and protection requirements, and has high flexibility. In addition, the steel cable tie has high strength and toughness, and can provide strong corrosion resistance while providing effective fastening force. In harsh environments such as outdoors, it can resist the erosion of rainwater or chemicals for a long time, extend the service life of the fixing device 2, and thus ensure the reliability of the entire sensor protection device.

[0036] In some embodiments of this utility model, in order to prevent the cover 1 from shifting in the horizontal direction, the contact portion between the fixing device 2 and the locking block 12 is provided with an anti-slip part to increase friction. The anti-slip part may be an anti-slip texture or a rubber layer on the upper surface of the fixing device 2, etc., and is not limited thereto.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
