Description

Technical Field

[0001] This utility model relates to the field of garage CO concentration monitoring technology, specifically to a garage CO concentration monitoring device with a protective structure. Background Technology

[0002] With the rapid development of urban transportation and the construction industry, the popularity of enclosed / semi-enclosed parking spaces such as underground garages and multi-level parking garages has increased significantly. While solving the "parking difficulty" problem, these spaces, due to their strong sealing and low air circulation efficiency, have become high-risk scenarios for carbon monoxide (CO) accumulation. CO, the main gaseous byproduct of incomplete combustion in car engines, is colorless, odorless, and highly toxic. When inhaled, it quickly combines with hemoglobin to form carboxyhemoglobin, hindering oxygen transport and causing dizziness, nausea, coma, and even death. Furthermore, its hazards have a "hidden outbreak" characteristic—when the concentration reaches 120 mg / m³... 3 At approximately 25 ppm, it poses a health threat to humans; concentrations exceeding 120 mg / m³ are also considered high. 3 At concentrations of approximately 100 ppm, CO can cause severe poisoning in a short period of time. Therefore, real-time and accurate monitoring of CO concentration in garages is a core element in ensuring the safety of personnel.

[0003] Existing garage CO concentration monitoring equipment can meet basic monitoring needs, but in practical applications, due to the special nature of the garage environment, there is a risk of external impurities entering the interior. The equipment generally suffers from problems such as insufficient protection capabilities leading to performance degradation and frequent failures. Therefore, we provide a garage CO concentration monitoring equipment with a protective structure. Utility Model Content

[0004] The purpose of this invention is to provide a garage CO concentration monitoring device with a protective structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A garage CO concentration monitoring device with a protective structure includes a monitoring device body, which includes a device shell. A protective cover is provided on the front side of the device shell. The protective structure composed of the protective cover and a dustproof net can specifically resist the damage of various impurities in the complex environment of the garage, reduce the damage of impurities to the key internal components of the monitoring device, and ensure that the device can collect CO concentration data normally without hindrance. On the basis of strengthening the protective effect of the device, it effectively improves the operational stability and service life of the monitoring device.

[0006] The device housing has locking grooves on both front sides, and locking holes are provided inside the locking grooves.

[0007] Both ends of the protective cover are provided with through slots, and dustproof nets are fixedly installed on the inner walls of both sets of through slots. The dustproof nets can effectively intercept dust particles, fallen leaves, solid impurities in vehicle exhaust, etc. in the air, and prevent impurities from adhering to the surface of the CO sensor inside the equipment or entering the circuit module, thereby preventing sensor sensitivity loss, short circuit and other faults, and ensuring long-term stable operation of the equipment in the complex environment of the garage.

[0008] A further improvement of this utility model is that: a frame is fixedly installed on all four sides of the protective cover, and the other end of the frame extends on the outer surface of the front side of the equipment housing.

[0009] A further improvement of this utility model is that a connecting cylinder is fixedly installed in the middle of the protective cover, and a working cavity is opened inside the prime number connecting cylinder.

[0010] A further improvement of this utility model is that a knob is provided on the outer surface of the left side of the connecting cylinder shell, and a bidirectional threaded rod is fixedly installed on the inner side of the knob. With the cooperation of the knob and the bidirectional threaded rod, the operator can easily complete the assembly of the protective cover and the equipment shell. Rotating the knob can drive the bidirectional threaded rod to rotate, thereby achieving quick assembly and disassembly.

[0011] A further improvement of this utility model is that the other end of the bidirectional threaded rod extends inside the working cavity and is rotatably mounted on the right inner wall of the working cavity. The bidirectional threaded rod is located in the working cavity inside the connecting cylinder, and is not affected by the outside world during operation. Similarly, objects from the outside world will not enter the working cavity, thus ensuring stable operation.

[0012] A further improvement of this utility model is that: the inner opening of the working cavity is provided with clamping blocks at both ends, and locking blocks are fixedly installed on the inner sides of both sets of clamping blocks. The clamping blocks and locking blocks are respectively connected to the interior of the matching engagement groove and locking hole. The clamping blocks and locking blocks are respectively inserted into the interior of the engagement groove and locking hole to form multi-directional limiting, effectively preventing the protective cover from loosening or falling off. Disassembly can be performed by operating the knob in reverse without the need for complicated tools. This not only ensures the stability of the protective cover during the operation of the equipment, but also facilitates the maintenance, repair or replacement of the dust screen of the internal components of the equipment in the later stage, improving the flexibility and convenience of equipment use.

[0013] A further improvement of this utility model is that: a brake block is fixedly installed at one end of each of the two sets of clamping blocks, and through holes are opened inside the two sets of brake blocks. The two sets of through holes are threaded onto the outer surfaces of both ends of the bidirectional threaded rod.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a garage CO concentration monitoring device with a protective structure. By setting up a protective cover and dustproof net to construct a graded protection system, it can ensure that the air in the garage carrying CO gas can smoothly enter the monitoring area, while effectively intercepting dust particles, fallen leaves, solid impurities in vehicle exhaust, etc. in the air. This prevents impurities from adhering to the surface of the CO sensor inside the device or entering the circuit module, thereby preventing malfunctions such as decreased sensor sensitivity and short circuits. It ensures that the device can operate stably for a long time in the complex environment of the garage, maintain the accuracy of CO concentration monitoring, and provide reliable data support for the life safety of people in the garage.

[0015] 2. This utility model provides a garage CO concentration monitoring device with a protective structure. Through the combination of a knob, a bidirectional threaded rod, a clamping block, and a locking block, the operator can easily assemble the protective cover and the equipment shell. Turning the knob drives the bidirectional threaded rod to rotate, causing the brake block to push the clamping block into the engagement groove, while the locking block engages with the locking hole, forming multi-directional limiting, effectively preventing the protective cover from loosening or falling off. Disassembly can be performed by simply reversing the knob, without the need for complicated tools. This ensures the stability of the protective cover during equipment operation and facilitates the maintenance, repair, or replacement of the dust screen for the internal components of the equipment, improving the flexibility and convenience of equipment use.

[0018] 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.

[0019] Example 1 like Figure 1-5 As shown, this utility model provides a garage CO concentration monitoring device with a protective structure, including a monitoring device body 1, the monitoring device body 1 including a device shell 2, a protective cover 3 provided on the front side of the device shell 2, through grooves are provided at both the upper and lower ends of the protective cover 3, dustproof nets 4 are fixedly installed on the inner walls of the two sets of through grooves, and a frame 31 is fixedly installed on all four sides of the protective cover 3, with the other end of the frame 31 extending on the outer surface of the front side of the device shell 2.

[0020] Furthermore, the protective cover 3 and the dustproof net 4 together form a graded protection system, which ensures that CO gas can smoothly enter the monitoring area. The air in the garage carrying CO gas must first pass through the channels at the top and bottom of the protective cover 3. The dustproof net 4 on the inner wall of the channel can intercept dust particles, fallen leaves, solid impurities in vehicle exhaust, etc., in the air, preventing impurities from adhering to the surface of the CO sensor inside the equipment or entering the circuit module, thus avoiding malfunctions such as decreased sensor sensitivity and short circuits.

[0021] Example 2 like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, engaging grooves 21 are provided at the front ends of both sides of the equipment housing 2, and locking holes 22 are provided inside the engaging grooves 21. A connecting cylinder 32 is fixedly installed in the middle of the protective cover 3. A working cavity 33 is provided inside the connecting cylinder 32. A knob 34 is provided on the outer surface of the left side of the connecting cylinder 32. A bidirectional threaded rod 35 is fixedly installed on the inner side of the knob 34. The other end of the bidirectional threaded rod 35 extends into the working cavity 33. The internal and rotatable components are mounted on the right inner wall of the working cavity 33. The inner opening of the working cavity 33 is provided at both ends with clamping blocks 36. Locking blocks 37 are fixedly installed on the inner side of both sets of clamping blocks 36. The clamping blocks 36 and locking blocks 37 are respectively connected to the interior of the matching engagement groove 21 and locking hole 22. Braking blocks 38 are fixedly installed at one end of both sets of clamping blocks 36. Through holes 39 are opened inside both sets of braking blocks 38. Both sets of through holes 39 are threaded onto the outer surfaces of both ends of the bidirectional threaded rod 35.

[0022] Furthermore, the protective cover 3 is aligned with the front end of the equipment housing 2, so that the frame 31 around the protective cover 3 fits against the outer surface of the front end of the equipment housing 2. Then, the knob 34 on the left side of the connecting cylinder 32 is rotated. The knob 34 drives the bidirectional threaded rod 35 fixed thereto to rotate synchronously in the working chamber 33. Since the two sets of brake blocks 38 are threadedly connected to the two ends of the bidirectional threaded rod 35 through the internal through holes 39, and the threads at the two ends of the bidirectional threaded rod 35 rotate in opposite directions, under the action of thread transmission, the two sets of brake blocks 38 will move closer to each other along the axial direction of the bidirectional threaded rod 35, thereby pushing the clamping block fixed thereto. When the brake block 38 moves towards the equipment housing 2, it causes the clamping block 36 to fully embed into the engagement grooves 21 on both sides of the equipment housing 2. At the same time, the locking block 37 on the inner side of the clamping block 36 will simultaneously engage into the locking hole 22 inside the engagement groove 21 to form a lock. The cooperation between the clamping block 36 and the engagement groove 21 restricts the displacement of the protective cover 3 in the front-back direction of the equipment. The cooperation between the locking block 37 and the locking hole 22 restricts the shaking of the protective cover 3 in the left-right and up-down directions of the equipment. Finally, the protective cover 3 and the equipment housing 2 are stably assembled. If the protective cover 3 becomes loose or falls off, it can also be quickly disassembled and reassembled.

[0023] The working principle of this garage CO concentration monitoring device with a protective structure will be explained in detail below.

[0024] like Figure 1-5As shown, during use, the operator aligns the protective cover 3 with the front end of the equipment housing 2, ensuring that the edges 31 of the protective cover 3 fit against the outer surface of the front end of the equipment housing 2. Then, the operator rotates the knob 34 on the left side of the connecting cylinder 32. The knob 34 drives the fixed bidirectional threaded rod 35 to rotate synchronously within the working chamber 33. Since the two sets of brake blocks 38 are threadedly connected to both ends of the bidirectional threaded rod 35 through internal through holes 39, and the threads at both ends of the bidirectional threaded rod 35 rotate in opposite directions, under the action of the threaded transmission, the two sets of brake blocks 38 will move relatively closer along the axial direction of the bidirectional threaded rod 35, thereby pushing the fixed clamping block 36 towards the equipment housing 2. When the brake blocks 38 move, causing the clamping block 36 to fully embed into the engaging grooves 21 on both sides of the equipment housing 2, the locking block 37 on the inner side of the clamping block 36 will simultaneously engage inside the engaging grooves 21. In the locking hole 22, a lock is formed. The cooperation between the clamping block 36 and the engaging groove 21 restricts the displacement of the protective cover 3 in the front-to-back direction of the equipment. The cooperation between the locking block 37 and the locking hole 22 restricts the shaking of the protective cover 3 in the left-to-right and up-to-down directions of the equipment. Finally, the protective cover 3 and the equipment shell 2 are stably assembled. If the protective cover 3 becomes loose or falls off, it can also be quickly disassembled and reassembled. When the equipment is running, the protective cover 3 and the dustproof net 4 together form a graded protection system, while ensuring that CO gas can smoothly enter the monitoring area. The air in the garage carrying CO gas must first pass through the through grooves at the top and bottom of the protective cover 3. The dustproof net 4 on the inner wall of the through groove can intercept dust particles, fallen leaves, solid impurities in vehicle exhaust, etc. in the air, preventing impurities from adhering to the surface of the CO sensor inside the equipment or entering the circuit module, avoiding faults such as decreased sensor sensitivity and short circuit.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
