To give a more specific example of an effective use, it is installed to collect and record information such as snow cover and changes in snow quality in areas where it is difficult to access mountain traffic, and to remotely monitor snow cover. In order to measure unit snowfall amounts and record the process of changes in snow quality due to accumulation, in other words the classification of snow layers, etc., it is linked with a remote-controlled automatic recorder to monitor and record snow conditions and snow quality. It can also be effectively used as a device.

Apart from these, it can also be used as a snow detection device for interlocking with a falling snow mountain motion control device for avalanche prevention, and a snow detection device for interlocking with a general residential roof snow removal device.

When a predetermined amount of snowfall is reached, the snowfall detection device sends a signal, which activates the linked automatic snowfall control device.
In order to prevent avalanches, it can be used in a wide variety of industries and in a wide range of applications, such as eliminating a small amount of snow that has been set in advance, and can also be effectively used as a snow detection device. This invention relates to a weight/bulk automatic measurement/detection/recording/weighing device.

To explain this embodiment with reference to the drawings, in order to measure, detect, record, etc. the footrest of the loaded object, an upper plate 1 that moves up and down and a lower plate 2 that is fixed are connected. The spring (A) 3, which supports the vertical movement of the upper plate 1, and the spring (
b) 4.41 or a pneumatic cylinder etc. is provided, and a repellent plate pusher 5 whose height can be freely adjusted is located at one end of the center of the upper plate;
Similarly, at one end of the center part of the lower plate, there are a spring seat 661 for the spring plate, a spring 7 for the spring plate, a base 8 for the spring plate, and a spring plate 10.10'.
Support both left and right ends of the board with spring plate supports 11°111.

When using spring R) 3.31 and spring (B) 4.4' for vertical movement, in order to fix this spring 6.3', use the upper plate to fix the spring 6.31 in contact with the upper plate. Spring seat (
B) Same as 12.121, upper plate spring seat (B) 13, 13
Attach the upper plate tilting magnet (A) 14.141 to the lower end of each upper plate spring seat ← eye 3.131, and attach the spring (A) 3.3' in contact with the lower plate 2. and spring (b) 4
．． In order to fix 41, lower plate spring seat @)15.15'
Similarly, there is a lower plate spring seat (b) 16.161, and the upper plate tilting magnet ←) 17.171 is similarly attached to each of the upper ends of the lower plate spring seat ←) 16.16'.

Furthermore, a switch mounting plate 18 and a switch 19 whose position can be adjusted freely are attached to the upper plate 1, and a sliding switch 19 is attached to the lower plate 2 to perform operations for signal transmission and recording. and install the switch sliding plate 20.

In addition, photoelectric switches 21 and 211 for measuring the bulk are attached to the lower plate 2 or another position, and a spring is used to move the upper plate 1 up and down with these elements. Depending on the purpose, parts such as repellent plates and magnets can be increased or decreased to adapt to the purpose.

As an example of implementation, in order to prevent the occurrence of avalanches in areas with heavy snowfall in mountainous areas, we can artificially generate avalanches, and reduce weight and bulk when used in conjunction with automatic falling snow control equipment and in conjunction with the amount of snow removal equipment on roofs of ordinary houses. To explain the automatic quantity measurement, detection, recording and measuring device in detail, the falling snow mountain movement control device or general residential roof snow removal device (hereinafter referred to as the snow removal device) and the automatic weight and bulk amount measurement, detection and recording metering device (hereinafter referred to as the detection device) are under the same conditions. Since the snow removal device and the detection device are installed at the bottom, the amount of snowfall on the surface of the snow removal device and the amount of snowfall on the top plate 1 of the detection device remain the same even if the amount of snowfall changes over time. The snow removing device is linked to the detection device, which performs double measurement detection, comparing the amount of snow with the weight itself and further comparing it with the set volume using a photoelectric switch, etc. The detection device always detects a predetermined amount of snow, and the snow removal device operates and stops according to the command, and the snow removal device automatically repeats the accumulation of snow on the surface of the snow removal device to perform snow removal work, so it is safe and easy to use. It is extremely efficient and can improve the snow removal effect with a small amount of energy.

The operation of this detection device is such that the pressure of springs or air pressure supporting the upper plate 1 is adjusted in advance according to the specific gravity and bulk of the snow to be removed, and when snow begins to fall on the upper plate 1. Due to its weight, the upper plate 1 starts to descend while compressing the pressure inside the pneumatic cylinder by the springs (A) 6.6' and the springs (B) 4.41i, and is attached to the upper plate 1.

The switch mounting plate 18 and the switch 19 are attached to the lower plate 2 as the upper plate 1 is lowered, and are installed on the upper part of the switch sliding plate 20 while sliding on the switch sliding plate 20. The first signal is transmitted through a first signal transmitting protrusion or contact whose height is adjustable, and transmits the first signal to a system-controlled program discriminator (not shown). This first
According to the signal command, a signal is sent to the pressure supply machine, etc., and the pressure supply machine, etc. responds to this and starts injecting pressure into the snow removal device.As snow continues to fall and snow accumulates on the top plate 1, the top plate 1 Continuing to descend, the switch 19 moves down without sliding on the switch sliding plate 20, and is provided at the bottom of the switch sliding plate 20.
Protrusion or contact 7 for second signal transmission with adjustable height
At the same time as the first signal passes through the
A second signal is sent to the station to record the predetermined snowfall i and the elapse of time, and this signal stops the operation of the 9 pressure feeder, etc., and also causes the ejector installed in the pressure supply circuit to stop the operation. ,
The pressure inside the snow removal equipment inn is rapidly discharged, and the snow removal equipment in the first stage is set to receive the snow removed and sliding down like the snow removal equipment installed in the upper part.

Spring (a) 6.31 and spring (b) for vertical movement
4. A repellent plate attached to one end of the center part of the upper plate 1 as a configuration for repeatedly detecting a predetermined snowfall amount using a+4 and repeatedly and interlockingly removing snow on the surface of the snow removal device at a predetermined snowfall amount. Similarly to the pusher 5 and the upper plate tilting magnet (a) 14, 141, which is also attached to one end of the center part of the lower plate 2 (
B) 17.171 is the standard configuration, and the operation with this configuration is that as the upper plate 1 descends due to snow accumulation, the center part of the splash plate pusher 5 attached to the upper plate 1 is moved. ,
The repelling plate pusher 5 presses down the repelling plate layer spring 7 while compressing it downward.

As the snow buildup progresses on the upper plate 1, the repellent plate pusher 5 compresses the repellent plate layer spring 7 further downward. For this reason, the repellent plate 10.101
The left and right ends of the upper plate 1 are tilted at one end of the upper plate 1 with the upper limit set at the time when a predetermined snowfall amount, that is, the amount of snow to be removed, is reached. to slide off the snow on the surface.

The main mechanical elements of this operation are the repelling plate pusher 5, the repelling plate layer spring 7, and the repelling plate 10. It is adjusted so that the time it takes to pass through the contact point is usually the same time.

Separately, as an auxiliary means to ensure this tilting operation, the top plate tilting magnet (A) 14.141 and (B) 17.171 are provided with the repelling plate 10.10'. The inclination of the upper plate 1 progresses as the upper plate approaches the lower limit of the inclination, and the magnet for upper plate inclination (A) 14. Same as 141 ←) 17
, 171 are attracted and ensure the tilting operation of the upper plate 1.

When the accumulated snow on the surface of the upper plate 1 is automatically slid off by these operations, the load on the upper plate 1, which has been adjusted to the predetermined amount of snow to be removed, and the springs 3 that were supporting this weight of snow are reduced. .3
', the upper plate 1 causes the switch 19 to slide past the protrusions or contacts on the lower and upper parts of the switch sliding plate 20, and sends respective return confirmation signals in the second and first order. At the same time, the time required for the downward movement of the upper plate 1, which is repeated six times, and its frequency are also recorded.

In addition, in order to check and record these operations more reliably, attach the upper plate tilting magnet (a) 14.1 a+ as necessary.
(b) A separate switch may be attached to the side of 17, 171, etc.

Photoelectric switches 21, 211, etc. are used to detect snowfall based on bulk, but the main purpose in this case is for double confirmation measurement detection with detection based on weight; It is sometimes used in combination to more reliably detect snowfall and to record changes in snow quality, such as changes in specific gravity. Switches such as the photoelectric switches 21 and 21' for detecting the amount of snow are installed on the lower plate 2 or at another location, and in order to detect a predetermined amount of snow, the heights of the light emitting part and the light receiving part are set in advance. - B [There is snow between the light emitting part and the light receiving part of the photoelectric switch 21, which is adjusted to a constant height, and the snow When the amount of snow reaches a predetermined height that should be commanded, the light emission and light reception become conductive or the light is blocked, thereby causing the photoelectric switches 21, 2
11 sends a signal to activate the pressure supply machine, and the pressure supply machine starts injecting pressure into the snow removal device.

When the snowfall progresses further and reaches the predetermined second snowfall that should be commanded,
The light emission and light reception are conducted or interrupted, and a signal is sent out in the same way as the detection at the time of the first snowfall amount, and at the same time, the operation of the pressure feeder, etc. is stopped, and at the same time, the ejector installed in the circuit is used to release the snow removal equipment. Release pressure rapidly.

As for the activation and stop signals for the pressure feeder, etc., the signal sent first is usually the signal sent by weight detection or the signal sent by bulk detection, and this causes the pressure feeder to etc., but the changes in each case, such as weight vs. detection time required for this, and volume vs. detection time required for this, are all determined by the signals sent from each. be identified and recorded.

In addition, the amount of snow to be removed can be adjusted using the spring (a) that supports the upper plate 1.
The length and compression force of 6.3' and (b) 4.4' can be changed, and the upper and lower spring seats (a) 12, 12' and (b) 13.
131 and (a) 15.151 and (b) 16.161
Alternatively, the length of each of the repelling plates 10, i o'
By appropriately combining or changing the lengths of both ends, the amount of snow removed can be finely and easily adjusted.

Furthermore, in order to accumulate snowfall and record changes in the amount of snowfall and specific gravity from one set time to another, the normal repelling plate mechanism and magnet for tilting the top plate (14° 141) and (b)
17. Remove all 171 and remove the springs (A) 6.31 (B) 4.41, the upper plate spring seats (A) 12, j2' and (B) 15.131, and the lower plate spring seats (I). ) Same as 15.151 (b) 16.161 with switch mounting plate 18 switch 19 switch sliding board - plate 2o is left in use, changes in snowfall amount per unit time from scheduled time to scheduled time, Changes in specific gravity, etc. can be identified and recorded using pattern recognition, program discrimination equipment, etc., and in order to record long-term snowfall conditions, snowfall can be accumulated as it is, and the amount of snowfall per unit time and the amount of snow Changes in snow quality, such as changes in the falling time of the top plate due to differences in the specific gravity and density of snowfall during the accumulation process, and changes in weight and bulk due to photoelectric switches and other switches are detected, and each change over time is detected. have them identified and recorded in a cross-sectional diagram.

Even when using a pneumatic cylinder etc. in place of springs (A) 3.31 and (B) 4.41, the above-mentioned repelling plate mechanism and upper plate tilting magnets (A) and (B), Each spring seat on the upper plate and the lower plate is normally unnecessary υ, and if necessary, switches can be mounted on the upper plate 1 and lower plate 2 using the plate 18 switch 1.
9 Attach the switch sliding plate 20.

When the upper plate 1 descends due to the weight of snow, the pressure in each cylinder is compressed, and the first signal and second signal accompany the lowering of the upper plate 1, and the second signal and first signal accompany the return operation of the snow removal amount. The function of starting or stopping the pressure feeder etc. by sending the signal is exactly the same, but when the upper plate 1 sends the second signal, the system control that receives this sends a signal to the valve in the pneumatic circuit,
The pressure in the cylinder such as air pressure corresponding to spring (B) 4.41 is rapidly reduced, and the repelling plate and upper plate tilting magnet (A) 14.14' and (1:+) 17.171 are attracted. Similar to the operation, one end of the upper plate 1 is kept tilted for a preset time to cause the accumulated snow on the surface of the upper plate 1 to slide off.

When the upper plate 1 receives the next return signal, the pressure in the cylinder such as air pressure corresponding to the spring (b) 4.4' is increased and returns to the horizontal position, and while returning to the old position, the second and first A signal is sent in this order to confirm the return to the old position, and at the same time record the elapsed time and frequency of the vertical movement.

Measurement and detection of accumulated snowfall amount and snow quality from a fixed time to a fixed time is performed and recorded in the same manner as a spring mechanism.

The above is an example of a snow removal device that is used as a measurement, detection, recording, and measurement interlocking device. Snow removal can be performed using this detector as a reference point, and can be controlled automatically and remotely, while also using low energy to remove snow. It functions effectively to achieve the purpose of When installed in an avalanche-prone area and used for a specific purpose, it fully demonstrates its characteristics.

As mentioned above, it not only measures weight using springs, air pressure, etc., but also detects bulk at the same time using photoelectric switches, etc. 1. It has a double confirmation function, and it can be continuously repeated using simple parts such as magnets and repellent plates. Since it is configured so that it can be measured and detected, it is possible to easily replace each part or increase or decrease the number of parts depending on the purpose, so you can freely select combinations depending on the purpose and object to be measured, detected, and measured. However, by combining these methods, it is possible to repeatedly carry out weighing multiple times and at the same time to discriminate the objects being measured, and depending on the purpose, it is also possible to collect the necessary information by accumulating it for υ unit time or even for a very long time. It has an unprecedented feature of being able to measure irregularly shaped items and detect their contents, and is even more efficient when attached to an automatic measuring and recording device on a conveyor line for mass processing. It is something that can be used for work.
