Description

Technical Field

[0001] This utility model relates to the technical field of air volume detection equipment, and in particular to an elevator car ventilation detection device. Background Technology

[0002] Elevator car ventilation inspection is a professional inspection of the operation status of the ventilation system inside the elevator car to ensure that it can effectively achieve air circulation. The inspection includes whether the ventilation device is operating normally, whether the air volume and air velocity meet the standards, whether the air duct is unobstructed, and whether there are any blockages or air leaks. It is an important part of the safe operation and maintenance of elevators, especially in densely populated or enclosed environments.

[0003] When testing ventilation devices with an anemometer, the airflow speed can be directly measured. Since the core of ventilation effect depends on air volume, the air volume can be calculated by multiplying the wind speed by parameters such as the area of ​​the ventilation opening. However, when using a handheld anemometer, the air volume at different locations cannot be measured due to the height of the car, which can lead to incomplete data. For example, the ventilation situation at the top or high places of the car may not be recorded, and problems of insufficient ventilation in certain areas may be missed. As a result, the results are not comprehensive and cannot accurately reflect the ventilation status of the entire car. It may also cause actual ventilation dead zones to be overlooked, affecting the judgment of whether the ventilation system meets the standards. Utility Model Content

[0004] The purpose of this invention is to provide an elevator car ventilation detection device that can flexibly adjust the probe height, solve the problem of limited height for manual detection, improve detection efficiency and accuracy, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An elevator car ventilation detection device includes a base and a hot-wire anemometer body. Multiple supports are movably connected to the bottom of the base, and a fixed rod is fixedly connected to the top of the base. A first telescopic rod is inserted through the fixed rod, and a second telescopic rod is inserted through the first telescopic rod. An adjusting frame is movably connected to the outside of the fixed rod. The adjusting frame includes a side rod, and multiple first clamping blocks are fixedly connected to one side of the side rod. Multiple clamping rings are fixedly connected to the side of the side rod opposite to the first clamping blocks. Probes are fixedly connected between the clamping rings. The probes are electrically connected to the hot-wire anemometer body via connecting wires. Second clamping blocks are fixedly connected to one side of each of the first clamping blocks, and a contact block is movably connected to the side of each second clamping block opposite to the first clamping block.

[0007] As a further preferred embodiment of this utility model, a press-type locking block is movably connected to one end of the first telescopic rod, and a press-type locking block is also movably connected to one end of the second telescopic rod. After one end of the first telescopic rod is inserted into the fixed rod, it can be limited by locking the press-type locking block into the corresponding slot in the fixed rod. Similarly, after one end of the second telescopic rod is inserted into the first telescopic rod, the press-type locking block at one end is also locked into the corresponding slot in the first telescopic rod, thereby achieving the limitation of the first telescopic rod and the second telescopic rod after stretching.

[0008] As a further preferred embodiment of this utility model, the outer sides of the fixed rod, the first telescopic rod, and the second telescopic rod are respectively sprayed with positioning marks. Multiple positioning marks are set on the outer sides of the fixed rod, the first telescopic rod, and the second telescopic rod, and each positioning mark corresponds to a different height mark, thereby facilitating personnel to pull the adjustment frame to adjust the detection height of the probe.

[0009] As a further preferred embodiment of this utility model, a pull rope is fixedly connected to the bottom of the side rod, which facilitates the gradual movement of the entire side rod from the second telescopic rod to the first telescopic rod and the fixed rod.

[0010] As a further preferred embodiment of this utility model, a connecting rod is fixedly connected between the two second clamping blocks, and an installation groove is provided at the middle position of one side of the second clamping block.

[0011] As a further preferred embodiment of this utility model, the contact block has multiple countersunk holes, and a limiting bolt is inserted into each countersunk hole. One end of the limiting bolt is threaded into the inner side of the mounting groove, and the contact block is inserted into the mounting groove through the limiting bolt. A compression spring is also fitted on the outside of the contact block. One side of the compression spring abuts against the inner side of the mounting groove, and the other side of the compression spring abuts against one side of the contact block. When the two sets of first clamping blocks and second clamping blocks are inserted into the fixed rod or the first telescopic rod and the second telescopic rod, the contact block can adaptively adjust its position by means of the force of the compression spring and abut against the outside of the fixed rod or the first telescopic rod and the second telescopic rod. This allows the side rod to slide and be limited in real time on fixed rods, first telescopic rods and second telescopic rods of different diameters by means of the two sets of first clamping blocks, second clamping blocks and contact blocks. This allows for quick adjustment of the detection height of the probe in conjunction with the positioning mark.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the probe height can be flexibly adjusted by using the telescopic structure of the fixed rod, the first telescopic rod, and the second telescopic rod, along with an adjustment frame. This solves the problem of difficulty in manually detecting ventilation at high places such as the top of the car, thus obtaining more comprehensive data. The contact block and compression spring work together to achieve stable positioning of the entire adjustment frame on the fixed rod, the first telescopic rod, and the second telescopic rod with different diameters, providing a more comprehensive reflection of the car's ventilation status and avoiding missing ventilation dead zones.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, the present invention provides an elevator car ventilation detection device, including a base 1 and a hot-wire anemometer body 20. Multiple brackets 2 are movably connected to the bottom of the base 1, and a fixed rod 3 is fixedly connected to the top of the base 1. A first telescopic rod 4 is inserted through the fixed rod 3, and a second telescopic rod 5 is inserted through the first telescopic rod 4. An adjustment frame 6 is movably connected to the outside of the fixed rod 3. The adjustment frame 6 includes a side rod 7. Multiple first clamping blocks 8 are fixedly connected to one side of the side rod 7. Multiple clamping clamps 9 are fixedly connected to the side of the side rod 7 opposite to the first clamping blocks 8. Probes 12 are fixedly connected between the multiple clamping clamps 9. The probes 12 are electrically connected to the hot-wire anemometer body 20 through connecting wires. Second clamping blocks 10 are fixedly connected to one side of each of the first clamping blocks 8. A contact block 11 is movably connected to the side of the second clamping block 10 opposite to the side of the first clamping block 8.

[0021] like Figure 1 As shown, a press-type locking block 13 is movably connected to one end of the first telescopic rod 4, and a press-type locking block 13 is also movably connected to one end of the second telescopic rod 5. After one end of the first telescopic rod 4 is inserted into the fixed rod 3, it can be locked into the corresponding slot in the fixed rod 3 by the press-type locking block 13 to achieve a limit. Similarly, after one end of the second telescopic rod 5 is inserted into the first telescopic rod 4, the press-type locking block 13 at one end is also locked into the corresponding slot in the first telescopic rod 4, thereby achieving the limit of the first telescopic rod 4 and the second telescopic rod 5 after stretching. The fixed rod 3, the first telescopic rod 4, and the second telescopic rod 5 are respectively sprayed with positioning marks 14. Multiple positioning marks 14 are set on the outside of the fixed rod 3, the first telescopic rod 4, and the second telescopic rod 5. Each positioning mark 14 corresponds to a different height mark, so as to facilitate the personnel to pull the adjustment frame 6 to adjust the detection height of the probe 12.

[0022] like Figures 2-4 As shown, a pull rope is fixedly connected to the bottom of the side rod 7, which facilitates the gradual movement of the entire side rod 7 from the second telescopic rod 5 towards the first telescopic rod 4 and the fixed rod 3. A connecting rod 15 is fixedly connected between the two second clamping blocks 10. An installation groove 16 is opened in the middle of one side of the second clamping block 10. Multiple countersunk holes 17 are opened in the abutment block 11. Limiting bolts 18 are inserted into the countersunk holes 17. One end of the limiting bolt 18 is threaded to the inside of the installation groove 16, and the abutment block 11 is inserted into the installation groove 16 through the limiting bolt 18. A compression spring 19 is also fitted on the outside of the abutment block 11. One side of the compression spring 19 abuts against... Inside the mounting groove 16, the other side of the compression spring 19 abuts against one side of the abutment block 11. When the two sets of first clamping blocks 8 and second clamping blocks 10 are inserted and connected to the fixed rod 3 or the first telescopic rod 4 and the second telescopic rod 5, the abutment block 11 can adaptively adjust its position by means of the force of the compression spring 19 and abut against the outside of the fixed rod 3 or the first telescopic rod 4 and the second telescopic rod 5. This allows the side rod 7 to slide and be limited in real time on the fixed rod 3, the first telescopic rod 4 and the second telescopic rod 5 of different diameters by means of the two sets of first clamping blocks 8, second clamping blocks 10 and abutment blocks 11. This allows the detection height of the probe 12 to be quickly adjusted in conjunction with the positioning mark 14.

[0023] It should be noted that this utility model is an elevator car ventilation detection device. In use, the base 1 is first placed in a suitable position inside the elevator car through the bracket 2. According to the detection requirements, the first telescopic rod 4 and the second telescopic rod 5 are stretched. The length of the overall structure is fixed by the pressing block 13 being inserted into the corresponding slot. Then, the side rod 7 is connected to the uppermost position of the second telescopic rod 5 through two sets of first clamping blocks 8, second clamping blocks 10 and abutting blocks 11. The air volume and wind speed of the ventilation device can be detected from top to bottom at a fixed distance. Then, with the help of the pull rope at the bottom of the side rod 7, the adjusting frame 6 is moved to a suitable height. That is, the first clamping block 8 and the second clamping block 10 cooperate, so that the abutting block 11 abuts against the fixed rod 3, the first telescopic rod 4 or the second telescopic rod 5 under the action of the compression spring 19, realizing the stable limit of the adjusting frame 6. At the same time, the height can be quickly determined by referring to the positioning mark 14. Simultaneously, the probe 12 starts to work and transmits the detected wind speed data to the hot wire anemometer body 20 through the connecting line. The staff can read the data.
